Objectives: The present study aimed to provide the fundamental data for guiding establishment of measures among the rural elderly population with physical disabilities. The specific goals of this report are to reveal the prevalence of their disabilities, its tendency according to their increasing age, and to assess the background explanations. Methods: The self-administered questionnaires have been performed 432 persons of rural residents age 40 and greater in Kumsan-Gun and Chongyang-Gun, Chungchongnamdo Province. The questionnaire items included presence or not. of disabilities. specific causes for disabilities, anthropometric measures, and amount of physical activities. Results: The proportion of disabilities was higher in women than men, and the functional degree of their limbs decreased with the increasing age. The proportion of disabling extremities was higher in the lower extremities than in the upper ones. Joint diseases were the most prevalent causes for disabilities of extremities. Concerning the degree of depression, 41.2% of study subjects were normal, 47.5% had mild depression, 6.3% moderate, and 5.1% severe depression, with no statistical difference based on age and sex. The worse are the functional degree of both extremities, the greater the degree of depression the subjects had. The odds ratio for presence of disabilities of extremities was 2.6 times higher in women than in men for sex and for age, 50's were 3.5 times, 60's 4.3 times, 70's 4.9 times than 40's, respectively, with increasing tendency with increasing age. The odds ratio for depression was 1.2 times greater in subjects with disabilities than in normal population with no statistical difference. Conclusions: More efforts are needed to establish elderly specific measures for providing proper public health services centering on maintenance of physical functioning among elderly population.

Objectives: This study was conducted to identify factors that affect medical service performance in rural health sub-centers and to develop a method to improve health sub-center performance that takes advantage of these insights. Methods: This study included 1,242 South Korean health sub-centers that had been in operation at least since December 31, 2009 as units of analysis. After adjusting for population differences between areas, the performance of medical service among health sub-centers was analyzed according to medical services performed per person. We performed t-tests, ANOVA, Scheffe's tests and multiple regression analyses. Results: The following were significant variables affecting the medical service performance of rural health sub-centers: number of hospitals and clinics, presence of community health practitioner posts, distance from health sub-centers to main public health centers, distance from health sub-centers to the nearest emergency medical facilities, and proportion of the local population aged 65 and over. In contrast, the proportion of the local population between ages 0-4 and the placement of public health doctors that had already completed their internship were not significant variables. Conclusions: The medical service performance of health sub-centers located in rural areas is significantly affected by local population and health care environment characteristics, and therefore, it is imperative to develop strategies to provide differentiated service based on these factors.

Drought index can be used to implement an early warning system for drought and to operate a drought monitoring service. In this study, an approach was examined to determine agricultural drought index (ADI) at high spatial resolution, e.g., 270 m. The value of ADI was calculated based on soil water balance between supply and demand of water. Water supply is calculated by the cumulative effective precipitation with the application of the weight to the precipitation from two months ago. Water demand is derived from the actual evapotranspiration, which was calculated applying a crop coefficient to the reference evapotranspiration. The amount of surface runoff on a given soil type was also used to calculate soil residual moisture. Presence of drought was determined based on the probability distribution in the given area. In order to assess the reliability of this index, the amount of residual moisture, which represents severity of drought, was compared with measurements of soil moisture at three experimental between July 2012 and December 2013. As a result, the ADI had greater correlation with measured soil moisture compared with the standardized precipitation index, which suggested that the ADI would be useful for drought warning services.

For people with disabilities, getting a job makes it possible to advocate their own human rights, to improve their self-esteem and self-efficacy, to narrow economic, psychological and social divide between them and those without disabilities and ultimately to attain social integration. According to recent statistical data, there was an increase in the weight of people with disabilities, but their economic activities were on the wane, and it's required to explore what curbs the employment of people with disabilities to find feasible solutions. The purpose of this study was to examine influential factors for the economic activities of people with disabilities. The subjects in this study were the selected people with disabilities in the metropolitan area, on whom a survey was conducted to make an empirical analysis. The findings of the study were as follows: The people with disabilities engaged in less economic activities when they were basic livelihood security recipients, when they were older, and when they were female. And those who underwent job training and who were certified technicians were more likely to participate in economic activities. Therefore differentiated policy setting is required to boost the economic activities of people with disabilities after their general characteristics, characteristics as human resources and characteristics related to vocational training are carefully analyzed. As for general characteristics, whether they are basic livelihood security recipients or not should be considered to assess the degree of their poverty, and their gender, age and presence or absence of spouses should all be taken into account. In terms of vocational training, their certificates and job training experience should be investigated.

The purpose of present study is to identify the regional tourism resources using Webometric network analysis. The study focuses on Suseong area in Daegu metropolitan city. Various kinds of web-based data, for example, hit counts, online news, and public comments, were used to discover hot places and people's responses. The research question is, 'First, what is the optimum level of the search engine for suseong? Second, what is the online appearance of tourist resources in suseong? Which region is the center of tourism with high levels of emergence? Third, what are the main contents of news articles and comments related to the Suseong pond?'. The results show that the search engine optimization level in Suseong is lower than that in other areas in Daegu. In other words, tourism information and contents regarding Suseong are not highly visible on cyber space. Importantly, Suseong pond had the highest online presence. A close analysis of both online news and users' comments on Suseong pond, however, revealed the biggest concern as calling for improving public accessibility to tourism infrastructure. The findings are expected to contribute to policy development and service operation related to tourism resources in Suseong.

The globalization of services is closely related to other economic problems facing the world today. These are: 1) the globalization of economic activities, 2) the servicization of economic activities. The world economy is now move interconnected than at any time in its history. Investment decisions, production processes, labor market regulations and even environmental legislation made by one country or company affect other economies, other companies and the lives of individuals. In fact, it is nearly impossible to think of a country that is not connected to the world economy in some form or another and it is no exaggeration to state that globalization is already an unassailable fact. The fabric of our economy and the way we do business are changing. This change is the transformation from a marketplace on goods to one focused on services. That is to say, we live and work in a service-centered, service-sensitive economy. As a result of the globalization an servicization of economic activities, services require the globalization, and services are increasing their international trade, foreign investment, agreements, alliances, mergers and collaboration networks. It is quite obvious that services are affected by globalization ; but raising the question by how much leads us to the paradox of service globalization, services represent 70% of the most advances economies but only account for less than 25% of international trade and almost half of direct investment; mergers and takeovers. These figures create a paradox that can be explained by two reasons. First; the natural(the service relationship) and artificial difficulties(barriers to trade) faced by the service sector that inhibits globalization. Second, the non-inclusion in official statistics of the share of internationalized goods that are due to services, for example intra-firm trade or the service value incorporated into exported goods. If these were taken into account the service trade figures would be extremely different. The first explanation can be subdivided into a number of elements. The OECD identifies six reasons:services cannot be stored; client-supplies interaction requires local presence; most service firms are SEMs; products are highly differentiated; cultural differences are especially important in this field; and, finally, trade barriers and restrictions on local operations exist. However, despite all of this, globalization produces clear advantages to suppliers. Therefore, the objective of this study is to explore the main forms of service globalization and differences between that of goods, and is to identify distinctive aspects of service globalization within the framework of the global economy.

There have been large concerns about survivability defined as the capability of a system to perform a mission-critical role, in a timely manner, in the presence of attacks, failures. In particular, One of the most important core technologies required for the design of the ITS(Intrusion Tolerance System) that performs continuously minimal essential services even when the computer system is partially compromised because of intrusions is the survivability one of In included the dependability analysis of a reliability and availability etc. quantitative dependability analysis of the In. In this Paper, we applied self-healing mechanism utilizing two factors of self-healing mechanism (fault model and system response), the core technology of autonomic computing to secure the protection power of the ITS and consisted of a state transition diagram of the ITS composed of a primary server and a backup server. We also defined the survivability, availability, and downtime cost of the ITS, and then performed studies on simulation experiments and two cases of vulnerability attack. Simulation results show that intrusion tolerance capability at the initial state is more important than coping capability at the attack state in terms of the dependability enhancement.

Under the Korean mental health circumstances where familistic culture is predominant and social resources are limited, siblings are an important presence that effect chronically mentally ill people's lives. Despite this fact, our society in some aspect overlooks their importance. Therefore, this study is focused on the role of siblings as caregivers of chronically mentally ill adults and is conducted to understand the relevant process and types of how siblings fulfill the role of caregivers. In order to achieve this goal, data was collected from nine study participants through individual interviews and focus group interviews and its contents were analyzed according to Grounded Theory. The results revealed that the siblings' experiences as caregivers of chronically mentally ill people were mainly categorized as 'carrying painful memory, responsibility, and concern about the obscure future of the mentally ill sibling and finding a caring role different from those of parents.' Moreover three types of sibling caregivers were recognized: 'reality-adapting, obligation fulfilling' type, 'sacrificial self-responsibility fulfilling' type, and 'growing guardianship creator' type. This research aimed to vividly deliver the voices of research participants and proposed social support and permanent planning services based on the experiences and desires unique to siblings.
