개인 맞춤형 멀티미디어 시대가 도래됨에 따라 점점 더 다양한 방송 콘텐츠를 소비하고자 하는 사용자의 요구는 콘텐츠 사업자로 하여금 콘텐츠의 과잉 공급을 부추길 가능성이 높다. 다양한 매체를 통하여 제공되는 다량의 콘텐츠는 사용자에게 각자의 취향 및 선호도와 관계없이 일방적인 시청만 할 수밖에 없다. 따라서 사용자는 넘쳐나는 콘텐츠 중에서 각자가 원하는 방송 콘텐츠만 선택하여 시간과 장소의 제약 없이 시청이 가능한 개인 맞춤형 방송서비스에 대한 필요성이 요구되고 있다. 상기 필요성을 충족시켜 줄 수 있는 대안 중에 개인 맞춤형 방송 서비스의 제공을 목표로 국제 표준화된 TV-Anytime이 좋은 대안이 될 수 있을 것이다. 본 논문은 국내 DCATV(Digital Cable Television) 환경하에서 사용자가 PDR(Personal Digital Recorder) 단말에 저장된 대 용량의 방송 콘텐츠를 효과적으로 저장 및 검색하기 위하여 방송 콘텐츠에 대한 정보를 기술하고 있는 TV-Anytime 메타데이터의 저작, 송출 및 수신하기 위한 방법과 이를 실제로 구현한 시스템을 제안한다.

Social security is concerned with ensuring all citizens maintain basic needs, community health nursing maintains and promotes health for all community members. Lately, This new area of community health nursing, concern social welfare has increased. The objectives of this study are, first, to analysis the activities of nurses at community social welfare institutes, second, to estimate nursing demand for social welfare areas. The study methods used were as literature review, an analysis of statistical data and case study etc. The analytical framework also included a demand analysis of nursing manpower in community social welfare areas. The major results are as follows; 1. Employees which work at social welfare institutes number 55,464, nursing manpower (including nurse aids) number 1,458 and this is 3% of the total employees. Within nursing manpower, nurses number 780, nurse aids number 670. 2. The rates of nurses among total employees were high in institutes for mental disorders and institutes for the age. 3. The salary level of nurses was lower than average and the rates of retirement showed a roughly middle level in welfare institutes. 4. The satisfaction level of nursing services was high, and it is the trend that nurses substitute for nurse aids which retire at social welfare institutes. 5. Nurse demand that follows legal criteria is 2,221, but only 35% are working. It is therefore insufficient from the minimum of 733 to a maximum 1433. 6. The sufficiency rates by institution were high at institutes for vagrants, aged and the handicapped. In conclusion, the conditions are of nurses which are working in with the social welfare institutes are poor. Also the number of nurses compared rates of demand were in surplus. But, the basic direction of welfare policy is universal-preventive and provision of the family and of community centered service, and nursing service demand in the social welfare institute will increase continuously, we predict. Therefore, we will need a positive plan such as the development of an inservice education program and the construction of an information collection system etc.

컴퓨팅 노드가 가지고 있는 자원을 고갈시켜서 본래 의도한 서비스 제공을 방해하려는 서비스 거부 공격에 대응하기 위해서는 어떠한 경우에도 반드시 유지되어야 하는 필수 서비스를 위한 중요 자원을 식별하고 위급 상황에 적절히 시스템을 적응시키고 재구성하는 방안이 필요하다. 본 논문에서는 이를 위하여 두 단계의 대응 방안을 제시한다. 첫 번째 단계로 한 컴퓨팅 노드 내에서 선택된 필수 서비스에 대해 자원을 동적으로 할당하여 공격이 성공한 후에도 필수 서비스가 유지될 수 있도록 한다. 이 조치에도 불구하고 노드 내에서의 충분한 자원 확보가 불가능해지면 두 번째 단계로 미리 준비된 다른 컴퓨팅 노드에서 사용자에게 투명하게 필수 서비스가 제공될 수 있도록 중복성을 적용하는 방안을 제시한다. 테스트베드를 구축하여 실험을 실시한 결과 기법의 타당성을 입증할 수 있었다. 기존의 다른 방법과 성능 및 비용을 분석하여 비교하였다.

Background: Primary health care (PHC) plays a major role to ensure the basic right and equal distribution of the essential health care services. This study presents comparative analyses of PHC in Korea and Uzbekistan, discusses the existing scenario and the challenges, and provides recommendations. Methods: This study reviewed secondary data from Korea's National Statistical Information Service and the State Committee of the Republic of Uzbekistan on Statistic, regulatory legislation, research reports, and policy papers by research and international institutions. We focus on comparing input and outcome health data, PHC structure, and health expenditure. Results: Overall health status of the population in Korea is better than in Uzbekistan; both countries achieved more than 95% immunization coverage. The reforms implemented in both countries provide initial health care service delivery. However, there are several challenges such as the distribution of the staff between urban and rural areas and interest of the graduates on specialization rather than working in PHC system. Conclusion: PHC plays an important role in the provision of medical services to the population, addressing both health and social problems; it is the best tool for achieving universal coverage for basic health needs of the population. The community health practitioners in Korea and nurses in Uzbekistan plays main role in universal coverage through providing essential health care services. Continuous reform of the PHC system should be directed to strengthen the capacity of the PHC staff in health promotion knowledge and activities as well as to encourage population to improve their own health.

A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows : 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent -coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on telephone interventions were identified : guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggestion, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be understood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for extended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

Cloud computing has been one of the most critical technology in the last few decades. It has been invented for several purposes as an example meeting the user requirements and is to satisfy the needs of the user in simple ways. Since cloud computing has been invented, it had followed the traditional approaches in elasticity, which is the key characteristic of cloud computing. Elasticity is that feature in cloud computing which is seeking to meet the needs of the user's with no interruption at run time. There are traditional approaches to do elasticity which have been conducted for several years and have been done with different modelling of mathematical. Even though mathematical modellings have done a forward step in meeting the user's needs, there is still a lack in the optimisation of elasticity. To optimise the elasticity in the cloud, it could be better to benefit of Machine Learning algorithms to predict upcoming workloads and assign them to the scheduling algorithm which would achieve an excellent provision of the cloud services and would improve the Quality of Service (QoS) and save power consumption. Therefore, this paper aims to investigate the use of machine learning techniques in order to predict the workload of Physical Hosts (PH) on the cloud and their energy consumption. The environment of the cloud will be the school of computing cloud testbed (SoC) which will host the experiments. The experiments will take on real applications with different behaviours, by changing workloads over time. The results of the experiments demonstrate that our machine learning techniques used in scheduling algorithm is able to predict the workload of physical hosts (CPU utilisation) and that would contribute to reducing power consumption by scheduling the upcoming virtual machines to the lowest CPU utilisation in the environment of physical hosts. Additionally, there are a number of tools, which are used and explored in this paper, such as the WEKA tool to train the real data to explore Machine learning algorithms and the Zabbix tool to monitor the power consumption before and after scheduling the virtual machines to physical hosts. Moreover, the methodology of the paper is the agile approach that helps us in achieving our solution and managing our paper effectively.
