Purpose: Regional public hospitals have implemented functional reinforcement projects, and the facilities to accommodate them have increased in size. Nevertheless users in hospital are concerned about space shortage and area imbalances. Therefore I will trace the factors and trends that influence the size, and derive the relationship between these and the uses' critical opinion. Methods: Among the indicators for determining the size of medical facilities, the number of beds and total floor area are the essential indicators that directly affect the composition of space and allocation of area inside the medical facility. The purpose of this study is to investigate the change and the factors of change on the these two indicators in regional public hospitals and analyze the trend of changes. Results: In accordance with support undertaking, regional public hospitals have been increased the number of chronic-based beds and expanded additional facilities such as O.P.D specialized centers, emergency centers and funeral homes for reflecting the needs of the regions and times. However, as a result of analyzing the area, regional public hospitals are growing in size mainly on the ward and O.P.D is only expanded the scope of functional reinforcement division but total area level of O.P.D is lower than the recent level. In addition, the levels of D&T, Supply, mechanical/electrical equipment area related to medical support and control environment quality are very low. This is because the functional reinforcement projects have been done without concerning diagnose the whole facility. Implications: If functional reinforcement projects are conducted, to cope with problems of space shortage and imbalance of area, it is judged that an architectural planning that comprehensively analyzes existing facilities and related departments should be included.

Purpose: The planning of medical facilities involves formulating a comprehensive medical basic plan, translating it into spatial dimensions through a space program. Feasibility assessment often relies on empirical methods like floor area per bed. However, with the shift towards specialized medical concepts, proportional scaling to bed numbers is challenging. This study proposes scale planning improvements during the feasibility assessment stage for comprehensive hospitals, analyzing cases using area determination factors and standard areas based on medical resources. Methods: The Korean Development Institute's Public Investment Management Center (KDI) identified issues in the scale determination of medical facilities in the Preliminary Feasibility Study Guidelines and investigated alternative approaches for determining the scale of a case that passed the preliminary feasibility study in 2019. The study assessed the feasibility of applying individual factors to determine not only the number of beds but also the scale at the sector and department levels. Additionally, a statistical analysis was conducted to examine the correlation between the total number of beds and various area determination factors. Results: Results suggest a strong correlation between total beds and major equipment needs, but in hospitals with <500 beds, this correlation weakens. Ward section scale is better calculated per ward type, not just total beds. Outpatient department scale depends on specialists, influencing treatment room numbers. Medical personnel play a crucial role in determining the scale of sections like rehabilitation therapy rooms, operating rooms, dialysis rooms, and overall facility scale.

To clarify the relationship between the medical supply(medical persons and goods) and the use of bed, the author has made comparison among OECD 24 countries. Per Capita Bed-days can be divided into Average Length of Stay and Admission Rate, and these three variables were regressed upon both In-patient Care Beds of all medical institutions including acute somatic, psychiatric, special, nursing homes and other long-term care and Share of Total Health Employment in Total Employment. The result of regression analysis shows a statistically significant positive relationship between In-patient Care Beds and Average Length of Stay, and negative relationship between Share of Total Health Employment and Admission Rate. In addition to Ordinary Least Square(OLS) estimation, amended Bounded Influence Estimation(BIE) was also made to adjust the influence of outliers. Japan shows a very large number of In-patient Care Beds and a very low Share of Total Health Employment, and this medical situation is judged to have close relation to her long Average Length of Stay and low Admission Rate.

This study is to grasp a trend of profitability classified by characteristics of hospitals and to analyze related factors. Subjects are 145 hospitals which have gotten the standardization audit by Korean Hospital Association during 1998-200l. Profitability was measured in the aspect of operation profit rate with operating margin to gross revenue as proxy variables. Independent variables were classified by general factors (ownership, number of beds, period of establishment, competition), financial factors (liabilities to total assets, current ratio, fixed ratio, total asset turnover, inventories turnover), and factors related to patient treatment (average length of stay, bed occupancy rate, new outpatient ratio, admission ratio of outpatients, number of patients per specialist, personnel costs per adjusted inpatient, administrative costs per adjusted inpatient). Hierarchical multiple regression analysis model was used in this study. As a result of hierarchical multiple regression analyzation of operating margin to gross revenue, adjustive $R^2$ of general factors was relatively more powerful. The factors had significant effect on operating margin to gross revenue were ownership(+), number of beds(+), competition(+), current ratio(+), fixed ratio(+), total asset turnover(+), personnel costs per adjusted inpatient(-).

Fish community structure between eelgrass beds and an adjacent unvegetated area was investigated. Fishes were collected monthly from two eelgrass beds (Gamak and Yeoja Bays) and one adjacent unvegetated area in the southern sea of Korea between February 2006 and February 2007. The number of species for the Gamak and Yeoja Bays were 33, 28, respectively, while 28 species were identified from the unvegetated area. Leiognathus nuchalis was dominant in both Gamak and Yeoja Bays, while Engraulis japonicus was dominant in the unvegetated area. Cluster analysis conducted on total number of individuals for each species produced 3 groups; group A (appeared only in winter regardless of eelgrass), group B (appeared in eelgrass beds during all seasons except winter) and group C (appeared in the unvegetated area during all seasons except winter). The most important differentiating species between eelgrass beds and the unvegetated area were Lateolabrax japonicus, L. nuchalis, Takifugu niphobles and Pholis nebulosa. Based on the results of this study we can assume that eelgrass beds function as a nursery ground for young fishes from spring to fall, but not in winter.

The purpose of this study was to analyze a trend of profitability classified by characteristics of hospitals and to analyze related factors. The data for this study were derived from survey material conducted by the Korean Hospital Association on 33 hospitals in Korea between 1993 and 2002. Profitability was measured in the aspect of investment profit rate and operation profit rate with net profit to total assets, normal profit to total assets and operating margin to gross revenue as dependent variables. Independent variables were classified by general factors (ownership, number of beds, period of establishment, region), financial factors (total asset turnover, liabilities to total assets, current ratio, fixed ratio, inventories turnover, personnel costs per operation profit, material costs per operation profits), composition of manpower and facilities(personnel and area per beds), productivity index(the number of daily patients per medical doctor, the number of daily patients per nurse), the score of quality assurance activities. First, Concerning the specialists per beds or area per beds and profitability of hospitals there was not statistically significant. Second, Those hospitals having the most daily patients per nurse had significantly higher profitability than the others, but the number of daily patients per medical doctor had little effect on the profitability. Thirds, Those hospitals having a higher proportion total asset turnover tended to show significantly higher profitability compared to other hospitals, but the liabilities to total assets and liquidity ratio had a little difference to the profitability. Those hospitals having a higher proportion personnel costs per operation profit and material costs per operation profits tended to show significantly lower hospital profitability compared to other hospitals. Fourth, In regression analysis, hospital profitability had negative relationship with personnel costs per operation profit or material costs per operation profits. While it had positive relationship with total asset turnover, the number of daily patients per nurse. In conclusion, private hospitals had higher profitability than that of public hospitals. Though factors related to profitability of hospital were different according to ownership, it is important for securing appropriate profitability by operating appropriate number of nurse, raising total asset turnover, and reducing personnel costs, material costs per operation profits. This study can be used as a baseline data for planning of hospital management. But the study may be limited in that the results cannot be generalized due to its small sample size. However, this longitudinal observation of 33 hospitals over ten year period has significant merit alone.

After medical insurance came into effect in Korea, health care system has undergone tremendous changes. Changing patterns of newly established clinics is one of them. To investigate changes and trends, a total of 10,184 clinics which were newly established from 1981 to 1990 were analysed. Data were obtained from the file of contracting medical facilities of the Federation of Medical Insurance Societies. The proportion of newly establishied clinics has increased gradually, so that they amount to 13% of the total medical facilities in Korea. Meanwhile, the number of newly established medium-size hospitals and general hospitals have decreased. The number of newly established clinics per 100,000 populations has increased in the all areas, but the rate of increase has decreased in the cities except in 6 major cities in 1990. The rate of increase in newly established clinics surpasses that of population increase. This study has identified the trend of young physicians' early driving into their solo medical practice than before. This indicates chance of the medical specialty training nowadays toughen due to the limited openings in residency programs. However, the sex ratio of physicians at newly established clinics has not changed. The decreasing tendency to open medical practice without beds and the increasing size of clinics are found in this study(The size has been measured in terms of medical manpower, of beds, and of medical equipment in this study). Two thirds of general practitioners have opened their clinics without beds, although such trend has been less in the case of specialists. All three indicators show increasing size, especially in the case of rural clinics. However, among them, the number of medical equipments has increased most significantly from 8.9 items in 1981 to 12.9 in 1990.

On the basis of monthly samples, we investigated the seasonal variation and feeding habits of amphipods inhabiting Zostera marina beds in Gwangyang Bay. Dominant species $(>1\%$ of the total number of amphipods) consist of 5 gammarids (Gammaropsis japonicus, Jassa slatteryi, Pontogenia rostrata, Atylus collingi and Ceinina japonica) and 1 caprellid (Caprella tsugarensis). Mean densities of amphipods varied from the highest of $63,148\;ind.\;m^{-2}$ in-May to the lowest of $1,247\;ind.\;m^{-2}$ in September. G. japonicus and J. slatteryi dominated in summer whereas C. japonica in autumn and winter. C. japonica was found to be a carnivorous feeder consuming mainly harpacticoid copepods and unidentified crustaceans, whereas G. japonicus, J. slatteryi, and C. tsugarensis consumed both phytoplankton and detritus. Seasonal densities of amphipods were significantly related with the shoot standing crop of the eelgrass and its epiphyte. Also densities of amphipods displayed significant difference in related with the shoot density of the eelgrass among sampling stations. These results suggest that the biological interactions between the eelgrass and amphipods as well as between the carnivorous and the herbivorous amphipods may be important in the seasonal variation of amphipods inhabiting Z. marine beds.

This study aims at providing necessary informations for management decision-making to the hospital manager, such as ratios of fixed and variable cost to total operating expense, and variable cost ratio to operating revenues, and determinant factors affecting cost behavior. A study model and related hypotheses were established, data were collected from 41 private university hospitals for the 6years from 1998 to 2003, and regression analyses were performed to test the hypotheses. The results of the analyses and conclusions are as follows; First, labor cost and administration cost within the same number of beds have not only fixed quality of the cost, but variable quality of that. Also, the ratio of the variable costs to operating revenue of the metropolitan was estimated 76.9% and that of other area hospitals was 80.1%. Second, the major factors affecting the increase rate of the operating expense were the increase rates of the number of inpatients, the number of employee, and the number of hospital operating bed. This result implies that maintaining a optimal hospital bed size and efficient operation of the beds are important strategic factors of hospital management.
