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 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.

이 연구는 젊은 연령집단의 선별적 이동 및 세대에 걸쳐 진행되는 단계적 이동이 농촌과 도시의 출산력 변화와 지역의 인구성장에 파급되는 과정을 시계열적으로 분석하는 것이 목적이며, 전라북도 14개 시군이 사례지역이다. 분석에 활용된 자료는 1970 1990 2010년 20-34세 연령집단의 지역 간 인구이동 O-D 행렬과 같은 기간의 20-34세 연령집단과 가임 여성인구 분포 및 출생 사망의 동태자료이다. 분석 결과, 첫째 각 시점의 젊은 연령집단은 큰 규모로 출생지에서 이출하는 선별적 이동을 했다. 둘째 세대별로는 앞선 세대는 과거 전라북도 농촌에서 도시로, 뒤따르는 세대는 현재 전라북도 도시들에서 수도권으로 이동하는 단계적 이동이 존재했다. 셋째 젊은 연령집단의 선별적 이출은 출산 가임인구 축소, 저출산과 고령화 그리고 자연적 인구감소라는 과정을 수반되는데, 단계적 이동에 따라 과거 농촌에서 이러한 과정이 진행되었고, 현재는 전라북도 도시지역에서도 진행되고 있다. 실제로 전라북도 대부분 군 지역은 1980년대 후반부터 연간 사망자수가 출생아수를 상회하는 자연적 인구감소가 나타났고, 2000년대 초반에는 도시 지역에서도 이 같은 현상이 확인된다. 따라서 단계적 이동은 비수도권 중소도시 인구성장을 결정짓는 주요한 원인이며, 결과적으로 정주계층을 따라 단계적 과소화로 이어지고 있다.

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.
