Answer
1. Instrument
The bassoon is one of the most unique and amusing looking instruments because of its long and thin shape. It may be played multiple ways, either being held horizontally or vertically, but there is no difference in sound or technique. It is a two-part instrument and is made of heavy wood. It’s probably the heaviest of all woodwind instruments. The bassoon is played with a double reed, so it is similar to the oboe but much more difficult to control. The double reed refers to two reeds tied together to form the instrument. This is supposedly a reference to a time when the bassoon was crafted from a single piece of wood and the player had to use their own double reed to make music. It has a wide range of sound and is used to play many different kinds of styles of music. Due to its complexity and difficulty, it has a very low chance of being played by a non-professional or a beginner musician. The instrument’s cost is average for an instrument, but it is still very expensive due to the maintenance of replacing and ordering reeds or any other replacement parts.
1.1. Key features of the instrument
The marimba is played with wooden, rubber, or yarn-wrapped mallets. The performer strikes the wooden keys, creating a bright, metallic sound that fades quickly. Other keyboard instruments (piano, celesta, harpsichord) share some similarities with the marimba, but none of these instruments’ mechanisms and materials produces the characteristically warm and percussive attack and sustain of the marimba. Keyboard percussion instruments are now more isolated in this category of sound generation. This idea is important to understand because it links the marimba to other keyboard percussion instruments, providing a future basis for marimba concerti and ensemble pieces. The marimba would not evolve into the exciting solo and ensemble instrument that it now is had its design and sound production not kept it largely isolated from the family of keyboard instruments.
1.2. Historical significance of the instrument
The historical significance of the harpsichord is mainly due to it being the main keyboard instrument in the Baroque period. It has been said that the sound of the harpsichord is the sound of the Baroque era. It evolved over a period of 150 years in response to changes in musical style and to the musical needs of composers. By the end of the Renaissance, the harpsichord had attained the shape in which it was to persist for about 200 years. Both France and Italy have played a large role in the history of the harpsichord. It is widely accepted that in the 15th century, the harpsichord had spread to many countries in Europe. Reaching a peak during the 17th century, especially in France, the harpsichord developed in terms of visual design, mechanical action, and sound quality. In France, two schools of construction exist: the Ruckers school and the Blanchet school. The Ruckers school produced intricate instruments featuring paintings or intricate inlay materials. However, such instruments may not play well from a musical perspective. Despite this intricacy, many Ruckers harpsichords were later converted into the plainer Blanchet design, demonstrating a musical emphasis during the later part of this period. In Italy, the harpsichord underwent mainly mechanical improvements. The most significant of the Italian builders were the Grimaldis, who developed an action which made it quick to play in contrast with the heavier sound of the French instrument. The harpsichord did not develop with the same success in England and Germany, both countries preferring the Clavichord and the Virginals. The harpsichord eventually became outdated in the late 18th century, being succeeded by the piano, although it has had a modern revival with interest in historically informed performance.
1.3. Notable performers of the instrument
Notable performers of the piano: It is far too difficult to encapsulate all of the world’s most famous pianists within one small list, given the monumental influence of the instrument. Many of the greatest composers themselves were pianists, so we have excluded them based on principal instrument to the composer’s title, i.e. F. Liszt would not be included as a pianist. We are left with no shortage of names no less. The Russian School of pianists has long been heralded as one of the most influential in history. From the incomparable audiences in artistry such as Sofronitsky and Richter, to the legendary teaching lineage from Goldenweiser to Neuhaus and Zak, pianists of Russian pedigree have wielded formidable prominence for close to a century. It is difficult to speak of great pianists without venerating Claudio Arrau, whose concert career spanned over eighty years. His recording of Beethoven’s ‘Hammerklavier’ sonata is still considered one of the most distinguished ever captured. Other notable pianists relevant to particular aspects of Beethoven interpretation include D’Albert, notable for his role in the Austro-German tradition and Schnabel whose recordings are seen as essential in appreciating the composer.

1. Introduction
In order for American businesses to be successful in a global economy, they must have a productive workforce. What happens when this workforce is suffering from a debilitating illness, such as mental illness? Is a productive workforce able to suffer from such an illness? This is a question that I often ask myself, and one that I will explore in this essay. In exploring this question, I will be drawing on evidence from an academic study done in New Zealand, in which sleep and mental health among a workforce were correlated (Clarke et al., 2006). The importance that this essay has is evident in the following quote: “Studies have demonstrated that the indirect costs associated with diminished productivity of symptomatic employees, absence from work, and reduced work efficiency on the job exceed the direct medical costs and represent a significant portion of the overall cost of depressive illness to employers” (Lerner et al., 1999).
1.1. Importance of Workplace Mental Health
A clearly communicated role within the organisation. Employees who do not know what is expected of them can become stressed and anxious. Providing employees with clear direction and identity can reduce these feelings, and can be achieved through effective management and regular discussion and review of employee roles.
A positive work environment that values and supports employees. This can involve identifying and utilising employee skills, providing ongoing development and training, and giving employees a level of autonomy in their role. Doing so can increase employee satisfaction and pride, which in turn enhances mental well-being.
Employers can create an organisational culture that enhances the well-being of its employees in a number of ways, many of which have a positive impact on the mental health of employees. The Centre for Workplace Mental Health (2017) identified the following protective factors that can reduce the risk of mental health problems occurring in employees.
Good mental health is fundamental for functioning well in everyday life, and is as important in the workplace as it is in our personal lives. As a result, the way in which a person’s mental health is handled by their manager and the culture of their workplace has a direct impact on that person’s productivity, morale, and well-being. One of the best ways to understand the importance of mental health in the workplace is to look at what employers can do to support the well-being of their employees.
1.2. Prevalence of Employee Depression
Mental health problems are one of the main causes of overall disease burden worldwide. Depression is cited as the third leading contributor to the global burden of diseases. A recent study of 24,000 employees in Europe found the average reported prevalence of depression to be 17.2% (range 2.8-28.4%). Depression has also been shown to have a higher prevalence among part-time workers compared to full-time employees. In another European study, depression was found to account for 50% of all absences from work and 37% of all work incapacity. The WHO has estimated that by the year 2020, depression will be the second leading cause of disability throughout the world. These figures and trends clearly indicate that depression is a highly prevalent disorder which will have an increasing impact on organizations throughout the world. Depression is a major cause of presenteeism (being at work, but not fully functioning) and employee turnover, which are both very costly for employers. It has been estimated that the economic burden of depression is 1% of the EU’s GDP, which equates to 200 billion euros. The impact of the recent COVID-19 pandemic is likely to further increase the prevalence of depression in the workplace. The pandemic has been associated with a large volume of job losses, financial strain, social isolation, and health anxiety due to increased risk and exposure to the virus. Recent data from the UK has shown that the prevalence of depression has doubled from 10% to 20% before and after the pandemic. Given the large impact and stigma of the mental health effects of COVID-19, it is likely these rates of depression will be further increased as the pandemic progresses.

Questions
Barriers to Effective Care Coordination:
Identify and explain at least 3 major barriers that can hinder effective care coordination for chronic conditions.
Examples:
Fragmented healthcare systems with limited communication channels between providers.
Lack of patient engagement and understanding of their care plan.
Socioeconomic disparities impacting access to healthcare resources and technology.
Propose solutions to overcome these barriers and create a more coordinated care system.

Answer
1. Fragmented healthcare systems
Effective coordination requires good communication between those involved, so limited communication channels between providers can act as a major barrier to coordination. Communication can be limited in a number of ways, the most simple being the inability to contact a specific individual. This was a common issue witnessed by the author while on a GP attachment. Secretaries often did not take messages from other healthcare providers or would take a message and not pass it on. Email contacts between providers are rarely available, and faxing is now outdated. Phone calls between providers are, of course, a good way of communication. However, without a direct line to the individual, the call is often lost. The use of voicemail is not an effective form of communication.
1.1 Limited Communication Channels
Healthcare systems have areas of specialization divided amongst different providers. This can lead to a patient receiving care from multiple providers within the same health issue, resulting in duplication of tests, uneven care provided, and varied outcomes. Patients with complex needs and chronic diseases often require treatment from multiple providers and specialties. Coordination of care for these patients is often inadequate due to the division of specialization among providers (James, 2003). Effective coordination is an essential component of good healthcare delivery and can be defined as the deliberate organization of patient care activities between two or more participants involved in a patient’s care to ensure that it is safe, efficient, and cost-effective. Coordination can be complex, involving tasks from different individuals across varying facilities and specialties (Gittell et al., 2000).
Introduction to Fragmented Health Care Systems
1.1 Limited communication channels
Providers in hospitals do not receive timely information about the discharge of their patients from the hospital or consultations with specialists. The quality and completeness of clinical information available at the time of a consultation was also identified as a problem, as well as difficulties in obtaining further information from hospital doctors. Changes in patients’ medications were often unclear and undocumented. General practitioners reported that they often had to admit patients to hospital because they could not obtain the medical or paramedical support necessary to sustain them at home or in a residential care facility. In some cases, hospital doctors would not accept patient referrals. These access block problems were perceived by general practitioners to be due in part to public and/or private hospital specialists having waiting lists of their own private patients, and being less inclined to treat public patients. Failure to provide follow-up treatment advice to referring doctors was described as a disincentive to further referrals. In mental health services, the lack of a booking system for patient appointments often complicated the task of arranging specific follow-up treatments. Most of New Zealand’s new health initiatives involve some level of care coordination from primary and community care. Examples include early discharge schemes, health of the older person and disability services programs, needs assessment and long-term care following the closure of hospital beds and the shift of a wider range of medical and surgical treatments from secondary to primary care. At present the potential gains of these initiatives are often not fully realized because they are not underpinned by improved communication and coordination with secondary care services. In some cases primary care doctors have been forwarded discharge and treatment change information for their patients months after the event, and because there is often no guarantee that hospital services will re-accept referred patients, primary care teams may give up on attempts to obtain further services that their patients still require. A lack of clear communication and understanding between the providers of secondary and primary care has also meant that some of the changes to service delivery described in the Introduction have occurred in a way that is ad hoc and unplanned.
1.2 Lack of information sharing
Virtual care coordination (e-health) has become more and more common, and is the use of IT services to plan and manage patient care. Most advances are in web-based, patient-to-provider cases, as they are easy to schedule, document, and revise. These cases have maximum coordination, but think about a patient who needs to see a specialist or get a procedure done. The patient instance again has much coordination with a defined specialist and a procedure time, but these cases are not easily transferable between different sectors of the health care system. He currently still has to fax or email procedure details, with possible drug specifications to his private practice proceduralist, which is basically less than a handoff, so this information could get lost or missed in potential coordination to a follow-up case.
The main issue with destroying the concept of an effective care coordination is that although there are several different forms of care coordination, most cannot be accurately displayed or compared to the traditional method of physician to patient, and the vegetative and emergency cases. Most of this essay is based around the transfer of information from one health care system to the next, and across the broad spectrum of managing the case. Care coordination has shifted to a multidisciplinary team effort over the past decade. The concept of care coordination is taking health care out of the passive mode and the linear patient to provider model, to design patient cases with an emphasis on preventing medical mistakes and anticipating potential setbacks.
1.3 Inadequate coordination between providers
Changes are needed to ensure the right type of coordinated mental health care is provided. For this to happen, mental health specialists must define in common terms what successful coordination will look like. It is too easy to say that coordination is occurring when a patient is seen by various providers in the same agency. Measures of coordination often involve event monitoring and evaluation of treatment effectiveness on the part of the patient and involved providers. Successfully coordinated care will result in a greater effectiveness of simpler treatments in the primary care setting and less need for referral to severe psychiatric medication management. With better measures of successful coordination, it will be possible to reward managed care organizations and provider groups that are coordinating mental health services and more effectively treating mental health patients.
Inadequate coordination between healthcare providers can adversely affect patient care. A healthcare provider may recommend different medications or a treatment course that interferes with treatment priority or diagnosis from another provider. Recommendations for, but no direct referrals to, psychological evaluation or therapy can be interpreted as stigmatizing patients and result in less motivation to follow a treatment course. Patient non-adherence is common in this chaotic healthcare system scenario, as patients often feel confused about proper treatment and may not believe therapy treatment will be effective. Then healthcare providers may misinterpret non-adherence as resistance rather than a problem with access and coordination, resulting in further exacerbating mental health problems. This lack of coordination for mental health treatment is in stark contrast to the care coordination in primary care and general medical settings.

Identify a case study of a patient with this chronic condition.
Analyze the strengths and weaknesses of the patient’s current care coordination plan.

Answer
1. Introduction
At present, there is an increasing number of people with chronic diseases. The evidence for this claim is in the 133 million Americans, or almost 1 in 2 adults, living with a chronic condition, and this figure is predicted to increase by more than 30% between 2000 and 2020 to 157 million with 81 million having multiple conditions. Projections suggest that chronic diseases will account for three-fourths of the total health care costs in 2023 – more than $4 trillion (Saint T, et al 2000). Chronic diseases are health problems that require ongoing management over a period of years or decades. They include, among others, arthritis, asthma, cancer, COPD, cystic fibrosis, diabetes, cardiovascular disease, and any form of mental retardation. A recent survey identified a total of 139 million Americans living with these diseases. These chronic conditions impact the lives of the people affected in many different ways. In 2000, the Surgeon General’s report on health and behavior revealed that 22% of people living with chronic diseases had limitations in daily activities compared to 3% of those without a chronic condition. People living with chronic condition are also at risk of dying prematurely. It has been shown that 90% of Americans’ annual deaths are caused by chronic diseases and 77% of employer costs are due to productivity losses in employees with chronic conditions. Healthcare providers have also been alerted to pay special attention to their patients living with a chronic condition. In 1998, the National Health Interview Survey (NHIS) reported that 70% of visits to a doctor’s office involved treatments for people with one or more chronic condition. With a large population affected by chronic diseases, care coordination is fundamental in assisting individuals to manage their conditions and improve their overall quality of life. Care coordination is a process that encompasses a wide array of functions and services that help patients with chronic conditions manage their health. Coordination involves organizing patient care and involves information sharing and communication between all participants concerned with a patient’s health to achieve safer and more effective care. Primary care physicians and patients play central roles in care coordination. Information from The Commonwealth Fund analysis in the Tri-Annual National Survey 2007 reported that patients with chronic conditions receive better care from primary care physicians versus specialists. Primary care physicians also report that chronic care management is one of the most challenging aspects of their job. This indicates that care coordination efforts need to improve in linking the efforts of generalists and specialists for patients living with chronic conditions. Improved care coordination ensures that the patient’s needs and preferences for managing their chronic condition are met and that healthcare decisions are agreed upon and followed by the patient. Coordination also supports the self-management of patients to become more involved with their care and in turn achieve clinical and personal goals they have set to improve their overall health. With these points in mind, this paper is centered on the case analysis of a patient named Clarence, living with diabetes, and the coordination efforts between healthcare providers to improve his health outcome.
1.1. Background of the Chronic Condition
Chronic diseases can be difficult to manage. They often need a lot of health services to manage their condition. This is what we call coordination of care. Coordination of care is a fragmented and an ad hoc enterprise with little standardization from patient to patient. Good, clear communication is key to effective care coordination. This is often lacking between primary care physicians and specialists, as well as between these providers and the ancillary services that play such a large role in managing chronic disease, such as pharmacies and laboratories. The way care is often managed and coordinated across the primary and specialty care settings, hospitals, home health agencies, and nursing homes provides an array of dangerous pitfalls for the patients and is an inefficient and expensive way to manage chronic disease. The case for this patient is all too common. This elderly patient has several chronic medical problems: congestive heart failure, hypertension, diabetes, and chronic kidney disease. The plethora of medical issues alone can create its own fragmented care and care coordination impaired by the individual concerns of each specialty involved in this patient’s care. As we detailed the patient’s experience throughout the hospitalization and elegant discussion of the pros and pitfalls of each stage of this patient’s care, it became clear that the systems currently in place provide many obstacles to effective care coordination. Good communication between providers with regard to the patient’s wishes and prior discussions about the care plan is an essential early stage in caring for a patient with chronic disease. Often the patients are not always clear to the physician about their own wishes, and many patients with multiple specialty involvement may have conflicting plans on how to address various issues in their health. This is an instance in which medical decision making becomes complex and difficult. Often a decision on paper A cannot be effectively communicated to provider B. Occurrences like this can lead to the patient’s avoidance of hospitalization for re-admission for an episode of heart failure symptoms.
1.2. Importance of Care Coordination
Care coordination is important to avoid gaps, overlappings, and delays in delivering the care that we need. Coordination may avoid, for example, conflicting treatments among our specialists or duplicate tests. Information is passed on about our needs and the activities of all the people involved in our care. With good information and a clear plan, the activities of the different people involved in our care are more structured and productive. Any changes in our health or the way we are managing our health problem are monitored, and the care plan is revised as necessary. In contrast, without effective care coordination, it is left to us to tell different health professionals what other health professionals are doing for us. We and our family members are forced to understand and keep track of the care that we are receiving and to recognize when it is not going well. Oftentimes, healthcare providers are not even informed about certain treatments or tests that the other providers have ordered. Good care coordination can prevent such burdens on patients and communication errors among providers. Information about changes in the patient’s health can fall through the cracks, with the result that no one takes responsibility for revising the care plan. A chronic care patient’s best choice among treatment strategies may not be considered because different providers are acting independently and no single professional takes responsibility for synthesizing the opinions of the various specialists involved.

Question

Answer
1. Introduction
The question is emerging about why detection and prevention of APTs was so low in 2013. The low detection is happening because target industries lack the capability to detect APT activities. APT attackers have high skill to cover up their activities and delete traces, making it hard to detect. Another reason is that the capabilities of traditional security measures such as anti-virus, intrusion detection and prevention, and firewall are not enough to detect and prevent APT. The existing security measures are only capable of detecting known attacks and malware, whereas APT attackers are using new malware and attack methods to compromise the target efficiency. Known malware and attack methods are actually still of minor use. This is what happened to Coca-Cola. Even though they have an information security program and traditional security measures, these are not enough to prevent their information from APT attacks. In 2009, Coca-Cola detected an APT attack plot on their networks. The attacks involved a group of hackers who were using advanced malware and remote system administration tools to gain unauthorized access to Coca-Cola’s network and affect the company’s operations. These APT attackers were trying to build persistence to stay within Coca-Cola’s network and steal sensitive information for a long time. But unfortunately, from 2009 to 2012, Coca-Cola lost its sensitive files to APT attackers. The results of forensic investigation on data stored in Coca-Cola’s breached systems have found that the malware had already deleted traces and the attackers had cleaned the remote administration tools. This investigation was conducted after Coca-Cola received reports of its sensitive files being copied by malware to unknown locations. In this case, migration of data from a well-known location, the unusual deleted file evidence, and support from reports can be indications of APT attacks.
1.1 Definition of Advanced Persistent Threat
Although the term “advanced persistent threat” has been popular since the early 2000s, it actually dates back to 2006. It is widely believed that the origin of the term APT comes from the United States Air Force. It is thought that they were the first people to use the term to describe a specific type of cyber threat. This belief is strengthened by a quote from a Lt. Col. Greg Rattray in 2009 stated, “The Airforce, by 2006, had identified the complete process of an advanced threat.” This quote shows that by that year they had a complete understanding of the processes and life-cycle of APT.
APT should not be confused with the term AET (Advanced Evasion Technique) which was proposed by network security firm Stonesoft. AET refers to means and methods that penetrate and exploit IT network vulnerabilities, while effectively evading network security systems, appliances, and controls. The AET attacks are the delivery and exploitation phase in the Cyber Kill Chain SM, the APT is the overarching structure and framework for the entire cyber kill chain.
An advanced persistent threat (APT) is a wide-ranging, sophisticated, sustained, and targeted attack against a specific group of people with the aim of achieving a specific agenda. An APT attack includes a number of different steps and a lot of different techniques often spanning a long period of time (such as several months or years). Anti-forensics methods, such as attempts to delete or alter log files, and false data injection, can also be and are often used in APT attacks, increasing the difficulty and complexity of detecting the attack and attribution.
1.2 Overview of Chinese Army Unit 61398
Chinese Army Unit 61398 is a cyber-warfare information operations unit of the People’s Liberation Army (PLA) of China. Though there is no public information about this unit’s numerical designator, it is commonly referred to by the identifier “61398”. Analysts have confirmed that APT activity surrounding Operation Shady RAT is being conducted using the resources of 61398, and APT attacks are traced back to infrastructure around Shanghai. It is unknown how many people work for 61398, but the number is suspected to be quite large and most likely staffed by a variety of military and civilian personnel. This is deduced from the sheer number of English-speaking APT operators observed online in Operation Shady RAT data who may or may not be native English speakers and the wide range of network intrusions into all sectors from this particular threat group.
