In the 21st Century, our society is facing decrease of general population and beginning of aging society due to low birth rate, and such issues are increasing the elderly population. Especially in Korea, the elderly population exceeded 7% of the total population in 2000, making its way to the aging society and the elderly population will increase up to 14% by 2019, becoming the true aging society. Unlike other countries, aging in Korea is happening very fast and this requires the society's preparation and plans to deal with the problem. This study was started with the problem that the welfare centers for elderly people in Gwangju do not have the space plan adequate for the regional characteristics and users' demands. Therefore, this study performed an investigation and analysis on service programs, management, and space formation of S welfare centers for elderly people in Gwangju. This study produced a figure after interviews with social welfare workers and surveys. And then this study investigated size and formation of space for the service programs in each welfare center This study showed the current status of welfare centers for elderly people and difference in size and formation of space related to the service programs of the region. Therefore, this study was done to provide the basic data for the space formation of new welfare centers.

The purpose of this paper is to estimate the effect of population change on waste emission in the case of Busan City. The results are as follows : First, population and waste emission in Busan City Show decreasing pattern since 1995. According to increase or decrease of population and waste emission, The 16 Gus in Busan City are categorited into 5 types. Comparing the difference of population and waste emission between 1995 and 2003, we find out a similar trend by 16 Gus in Busan City. Second, the waste emission shows the positive relation with the number of population and the land by use. But there exists multicollinearity between population and the land by use, and the population is considered the main factor of waste emission. Third, the population causes 92% or more of the waste emission in Busan City, and future researches are required for the additional causes of waste generation.

The battlefield environment of the Korean peninsula is rapidly changing due to the advancement of the weapon system brought by the political situation of adjacent countries and the 4th industrial revolution. The reduction of population also caused a sharp drop in the recruitment of military personnel, making it unavoidable to reform the military structure. This meaningful study is timely with recent news reports on the shortage of recruitment by 10,000 persons in the last five years. Universities are also seeing a decrease in the number of new students due to the reduced school-age population, and affiliated universities are responding to this issue with great seriousness. With a reduction in manpower, requirement-handling military units need to step up their efforts to secure competent noncommissioned officers while affiliated universities must also train capable noncommissioned officers. As a solution to the matter at hand, this study aims to suggest a method that may vitalize both the navy and the navy-affiliated universities based on the results of literature research.

The purpose of this study was to predict the future urban activities effectively and rationally. For the purpose, a simulation model, based on SD, was built by integrating economic activities, land use and traffic of a city and by dividing Daegu Metropolitan City into seven districts and one county. To identify the effect of the development of a new city in the Dalsung County area, the future population and traffic volume of the city were predicted, using the model. The results are summarized as follows. The future population according to the development of a new city in the Dalsung County area was predicted, and the effects before and after the development twenty years later were compared. The future population of the Dalsung County was found to have slightly increased, whereas that of the adjoining Dalsuh Metropolitan District was found to has slightly decreased. For the other districts, there were no changes of the future population. It was found, therefore, that the development of a new city would have no effect on other districts. Then, the traffic volume according to the development of a new city in the Dalsung County area was also predicted. It was found that in the initial stage the traffic volume would increase with the increase in population of Dalsung County. It was predicted that particularly,. the traffic volume for the purpose of business would greatly increase. The traffic volume of Dalsuh Metropolitan District showed a slight decrease, whereas for the other districts, there were no changes of the traffic volume.

The purpose of this study is to analyze the influence of the selective migration of young age group and the stage migration which has proceeded through generations, on the transition of fertility and the population growth in the rural and urban in the case of Jeollabuk-do. For this, we use O-D matrix of 20-34 age group, the distribution of that group and women of child bearing age, and vital statistics in 1970-2010. The major findings of this study are as follows. First, the outflows from their birth place are common and dominant features of 20-34 age group in each time. Second, there is the stage migration which preceding generation moved from the rural areas to the cities in Jeollabuk-do and following generation has moved from the cities to Seoul metropolitan area. Third the selective outflow migration of young age group has leaded to reduction of the childbearing population, declining birthrate, aging and natural population decline. Due to the stage migration, these depopulation processes occurred in rural area in the past, and currently it expands to the cities with about 15 years time gap. In fact, there have been the natural population decrease which annual number of deaths exceed that of births from the late 1980s in the most rural areas and in the early 2000s, such a phenomenon has been confirmed also in urban areas. Therefore, this study concludes that the stage migration through generations is one of the crucial factor to the population growth in local cities and also brings out the step-wise population decrease in settlement hierarchies.

The yeast population on 14 species of seaweeds and in water estimated by cultural mothods over a 5-month period in south-west in Korea, Nine species of yeasts, comprising unidentified one, and one of yeast-like fungi were identified. Fifty phycase were attributed to the difference of cultural method between the present work and earlier repoeters and, to some exent, the higher number of Rhodotorula glutinis which had a prior adaptation to the release of inhibitory polyphenolic materials. Although, to what extent, all division of algae showed a similar variation in yeast population, correlated with month, the rapid decrease of yeast population in August seems to be the cause of exposure of heat irradiation in this month. The cultural estimate of per se fltration without double filter and one of unidentified species are discussed.

According to the provisions of the United Nations, the proportion was 65 years of age or older population is 7% more than in the total population aged society. Due to the rapid decrease fertility and medical technologies and the improvement of living standards, the average life expectancy has emerged as an aging society. In the case of our country, and in 2011 the proportion of the population aged 65 and over 11.4%, the future is even faster aging rate is expected to launch in 2026, the super aged society. The days went by relying on caring for personal piety. Nursing crime is often due to the patriarchal family culture and afford. To care for patients with severe human or plant in the home, not to assume that society. Expanding the scope of long-term care insurance service person and the family burden reduced through measures to apply for health insurance, nursing care can prevent crime.

The purpose of this study was to evaluate the clinical efficacy of a standardized special ethanol extract from Gynostemma pentaphyllum as a management for anxiety and stress of normal population. This is a two-arm, parallelgroup, randomized, double blind clinical trial comparing Gynostemma pentaphyllum extract 200 mg bid (GP-EX, n=48) or placebo bid (n=54). The main outcome measures were the decrease in anxiety sensitivity index (ASI), the State version (S-STAI) of the Stait-Trait Anxiety Inventory (STAI) and the Trait version (T-STAT) of the STAI from baseline over a 6 weeks treatment period. In more anxious group (S-STAI50 or ASI19), the anxiety in group with GP-EX was decreased significantly than one in normal population with placebo [S-STAI50: T-STAI = from $57.7{\pm}6.5$ ($mean{\pm}S.D.$) to $46.8{\pm}11.2$ in normal population with GP-EX, p=0.002 vs. from $54.1{\pm}9.9$ to $49.0{\pm}9.6$ in normal population with placebo, p>0.05; ASI19: T-STAI = from $47.2{\pm}12.0$ to $42.4{\pm}11.1$ in normal population with GP-EX, p=0.022 vs. from $48.7{\pm}11.5$ to $46.0{\pm}10.4$ in normal population with placebo, p>0.05]. The most frequently reported adverse reactions considered possibly related to treatment were mild gastrointestinal events. GP-EX is more effective than placebo and is well tolerated as a therapy for anxiety and stress of normal population.

Dispersal of Xanthomonas axonopodis pv. citri, causing citrus bacterial canker disease on Unshiu orange was investigated at previously infested plots at Seogwipo in Jeju island of Korea. The bacterial pathogen overwintered in lesions started to multiply at tate May, and disease firstly observed one month after detection of phage from lesions. The disease gradually increased, however, it dispersed non-directionally to nearby plants from inoculum sources. Diseased plants were aggregated to form a cluster throughout the experiment. Population dynamics of phage on symtomless leaf surface and the disease severity were compared in the nursery, Increase of phage population on symptomless leaf surface preceded one month to that of the disease severity Population of phage increased constantly from late July to October, however, the disease severity decreased from late August to late October. It was assumed that the decrease of disease severity might be due to disease-induced defoliation.

The research was performed to compare to the biofilm characteristics and phenol removal efficiency in RBCs(Rotating Biological Contactor) using Rhodococcus sp. EL-GT(single population) and activated sludge(mixed population) as inoculum. Both reactors showed similar tendency on variations of dry weight, thickness and dry density of biofilm. However, the growth of biofilm thickness in 3 and 4 stage of single population reactor has sustained longer than that of the mixed population reactor. Unlike the mixed population reactor, the dry density of biofilm in the single population reactor had a difference between 1, 2 stage and 3, 4 stage. The single population reactor was stably operated without the decrease of phenol removal efficiency in the range of pH 6 ~ 9 and 15mM phenol was completely degraded in these pH ranges. But in case of the mixed population reactor, the phenol degradability was dramatically decreased at over 5mM phenol concentration because of the overgrowth and detachment of its biofilm.
