This study has attempted to show general characteristics of health centre directors who have served the post of directorship during the last 40 years. Of 3,000 such health centre directors, information on about 2,500 directors was collected. While average length of service for health center directors has increased, that of vacancy period has decreased. Rural areas have a shorter average length of service than the urban area. Rural areas have twice longer length of vacancy period per health center. Kangwon-do has the longest average length of vacancy period since 1980(2.79 months/year), and Daejeon has the shortest length of vacancy period(0.21 months/year). Chung-buk has no physician directors. The civil servant's rank for the directorship has promoted from the fifth level to the fourth level since 1990. A comparison between the physician director & non-physician director was made as follows : first, the proportion of physician directors had maintained rather high before 1980 s; 62.5% in 1963, 78.3% in 1970, 70.4% in 1980. It decreased to 44.1% in 1990 and 47.6% in 1997. Instead, non-physician directors has abruptly increased since 1980s (12.4% in 1980, 55.4% in 1990 and 50.8% in 1997). Second, physician directors mainly locate in the urban area(58.0% in 1997), but non-physician directors mainly in the rural area(67.2% in 1997). Third, since 1980, the average length of service for physician directors and for non-physician directors has become similar. Fourth, the mean age of physician directors is 45.1 years, and that of non-physician directors 55.7 years. The latter is 10 years older than the former.

We consider a k-out-of-n system with repair under T-policy. Life time of each component is exponentially distributed with parameter $\lambda$. Server is called to the system after the elapse of T time units since his departure after completion of repair of all failed units in the previous cycle or until accumulation of n-k failed units, whichever occurs first. Service time is assumed to be exponential with rate ${\mu}$. T is also exponentially distributed with parameter ${\alpha}$. System state probabilities in finite time and long run are derived for (i) cold (ii) warm (iii) hot systems. Several characteristics of these systems are obtained. A control problem is also investigated and numerical illustrations are provided. It is proved that the expected profit to the system is concave in ${\alpha}$ and hence global maximum exists.

Recently, an SSD with hybrid buffer memories is actively researching to reduce the overall latency in server computing systems. However, existing hybrid buffer policies caused many swapping operations in pages because it did not consider the overall latency such as read/write operations of flash chips in the SSD. This paper proposes the clock with hybrid buffer memories (CLOCK-HBM) for a new hybrid buffer policy in the SSD with server computing systems. The CLOCK-HBM constructs new policies based on unique characteristics in both DRAM buffer and NVMs buffer for reducing the number of swapping operations in the SSD. In experimental results, the CLOCK-HBM reduced the number of swapping operations in the SSD by 43.5% on average, compared with LRU, CLOCK, and CLOCK-DNV.

This purposes of this study is to develope policies on the facilities for the elderly care in Korea. Methodology of this study adopts comparative analysis on the facilities for the elderly care in 6 countries which have experienced various problems on the elderly. These 6 countries are Japan, Sweden, America, Australian, England and Germany. Major issues for comparative analysis are the standard of care facilities, residence condition, finance of facilities establishment and expense, operating system, management, and the law and administrative structure about the facilities for the elderly care. The elderly people need various kinds of welfare services such as medical care facilities, nursing home facilities, home care facilities etc.. Thus the public policies for the aging population nations are compose of income maintenance program, health and medical care services and social welfare services. The policies of facilities for elderly care are very important since these policies include the characteristics of income maintenance, me\ulcorner미 care program and welfare program. This study willsupply basic data for the development of facilities for the elderly care in Korea, especially conceming the system and institutional device of the facilities.

Objectives: The purpose of this study was to provide policy directions for air pollution reduction by analyzing the variation in the characteristics of air contaminants around the Gyeonggi Province area. Methods: The data used in the study was obtained from air quality monitoring stations operated by the Gyeonggi Provincial Government. The target area was the air quality management area of the Gyeonggi Province region. Results: The concentration of $PM_{10}$ (particles measuring $10{\mu}m$ or less) in 2009 was $60{\mu}g/m^3$, which has been reduced by about 2.7% per year after improvement countermeasures were emplaced. The air pollution control policy was especially more effective for coarse particulate matter (CPM, $PM_{10-2.5}$). The improvement of $NO_2$ pollution was generally very low, especially in cities which had considerable automobile traffic. The concentration of $SO_2$ pollution was rapidly improved in industrial areas, but did not show any difference for multiple and general cities. The predicted concentration of $PM_{10}$ for 2014 based on the trend over 2001-2009 was $53.4{\mu}g/m^3$, which fails to meet the target concentration of $40{\mu}g/m^3$. The predicted concentration of $NO_2$ shows a very low probability of achieving the target concentration of 22 ppb, and thus the current improvement of air quality has proven unsatisfactory. Conclusion: Air pollution control policy should be enforced according to regional pollution characteristics in order to obtain maximum effectiveness in improvement.

Background: Suicide is one of important health problems in Korea. Previous studies showed factors associated with suicide in individual levels. However, suicide was influenced by society that individuals belong to, so it was required to analyze suicide in local levels. The purpose of this study was to analyze the regional disparities of suicide mortality by gender and the association between local characteristics and suicide mortality. Methods: This study included 229 city county district administrative districts in Korea. Age- and sex-standardized suicide mortality and age-standardized suicide mortality (male/female) were used as dependent variables. City county district types, socio-demographics (number of divorces per 1,000 population, number of marriages per 1,000 population, and single households), financial variable (financial independence), welfare variable (welfare budget), and health behavior/status (perceived health status scores and EuroQol-5 dimension [EQ-5D]) were used to represent the local characteristics. We used hot-spot analysis to identify the spatial patterns of suicide mortality and negative binomial regression analysis to examine factors affecting suicide mortality. Results: There were differences in distribution of suicide mortality and hot-spot regions of suicide mortality by gender. Negative binomial regression analysis provided that city county district types (city), number of divorces per 1,000 population, financial independence, and EQ-5D had significant influences on the age- and sex-standardized suicide mortality per 100,000. Factor influencing suicide mortality was the number of divorces per 1,000 population in both male and female. Conclusion: Study results provided evidences that suicide mortality among regions was differed by gender. Health policy makers will need to consider gender and local characteristics when making policies for suicides.
