  • The polycyclic aromatic hydrocarbons(PAHs) content in sewage sludge was determined by gas chromatography linked to ion trap mass spectrometry(GC/ITMS) with five deuterated PAHs as internal standards. The minimum detection limit was from 1.66 to 7.14 pg for individual PAH by GC/ITMS. For determining total PAHs(∑PAH) in sewage sludge 84 samples from 74 waste water treatment plants in whole country were analyzed. The average content of ∑PAH far whole samples was 3,289$\pm$3,098 $\mu\textrm{g}$/kg, and ranged from 142 to maximum 20,102 $\mu\textrm{g}$/kg. According to the number of population of the city, the areas were classified as five regions, ie. big, large, middle, small, and rural area in which the waste water treated plants were grown. The contents of PAHs were 4,689$\pm$5,503, 5,839$\pm$6,401, 3,725$\pm$2,053, 2,237$\pm$2,069, and 2,475$\pm$1,489 $\mu\textrm{g}$/kg, in big, large, middle, small, and rural area, respectively.

  • 1) Lee-Su village is located in a riverside of an upper Tu-men river. Since an upper stream of Tu-men river is narrow and easy to pilot a boat, early in the past, it facilitated the form of the village near to the North Korean. 2) The form of the village is parabolic from the founding period. That is, increasing the number of houses in the time of the Cultural Revilution Campaign, and the Japanese colony, the village has transformed into the bigger size about 72 families from the small town. After the cultural revolution, due to private asset allowed in accordance with the Chinese Reform and Open Policy, the number of families in the town and the population have been decreased. As a result, 28 families live in the village currently. 3) The town which was well-ordered in the Japanese colonial period has been changed to a very disordered and agricultural town, owing to the decrease of the families A road system has been also ruined naturally in accordance with the decline of the number of the families.

  • The study aims to figure out the problems of Daldongnae (hillside shantytown) in Jaman-dong, Jeonju, and to propose the countermeasures for village regeneration. Based on the survey of current conditions in the area and the case study of successful regeneration projects, this study suggests regenerating concepts for the community. The study on the current state analyzes that Jaman-dong is faced with the population decline, especially among the young, the lack of community facilities and infrastructure, and the unfavorable situation in the residential environment. The case study involves three successful Daldongnae regeneration projects: the culture-based regeneration of Cultural Village (in Gamcheon-dong, Busan), the regeneration focused on healthcare and education of Ibagugil (in Choryang-dong, Busan), and the community-led regeneration of Rainbow Village (in Dae-dong, Daejeon). The regenerating concepts for the community are as follows: utilizing the existing local community center as a gathering place for the residents, furnishing a cultural space for a growing number of visitors, adding new parking space, installing convenient facilities in order to provide better pedestrian environment for the disabled and elderly, improving street landscapes, and establishing citizen participation programs.

  • Recently (2019), more than 3,800 schools have been closed in Korea due to the decrease in the number of students. Among them, 1,000 closed schools were used, 400 unused closed schools were sold, and the remaining 2,400 were sold. However, considering the absolute lack of elderly facilities due to the aging population, it seems necessary to recycle these public assets into elderly facilities. The purpose of this study is to explore the cases of remodeling closed schools in Japan and recycling them as elderly facilities, and to find ways to resolve the very serious shortage of elderly facilities while seeking measures to closed schools in Korea. The results of this study are summarized as follows: 1) In the case of Shinagawa in Tokyo, it was easy to change its use because the building was owned by the old district. 2) The existing classroom space was used as it was to create an elderly living space consisting of two or three rooms and one bathroom unit. 3) In case 2, even if the earthquake-resistant structure was reinforced, the overall construction cost was reduced by 30% compared to the new construction.

  • Since forest trees form the basis of forest ecosystem, their prolong subsistence is crucial for various flora and fauna. The foremost challenges to sustain the forest ecosystem comprise of the declining forest tree population accompanied with structural changes due to afforestation and exploitation of forest area, environment changes, pests, pollution, and introgressive hybridization. For ex situ conservation approach, in vitro techniques encompass basic role for conserving tree genetic resources, predominantly where natural propagules like recalcitrant seed might not be appropriate for long-term conservation. The practice includes restricted growth techniques, conventional micropropagation, production and storage of synthetic seeds, and cryopreservation. Even though these practices have been applied chiefly to herbaceous species, but recently, woody species were also focused upon. Key conceptions, challenges and techniques for forest tree seed conservation are discussed briefly in this review with special emphasis on some successful cryopreservation approaches for long-term storage.

  • The purpose of this study was to elucidate the general characteristics, antheropometric values and health-related characteristics of the rural elderly population according to their Sasang constitutions. The participants in this study were 31 in Taeeumin group, 29 in Soyangin group, and 15 in Soeumin group. The present study was performed using self-administration questionnaires, antheropometric and biochemical analysis. There were no significant differences in height, weight, BMI, diastolic blood pressure and alcohol habits between the Sasang constitutions. In the analysis of physical activity, Soyangin had a higher value than the other groups. Compared with the other groups, Soeumin also had considerable resistance to stress($101.1{\pm}26.2$ point). Furthermore, in the analysis of fatigability caused by stress, Soeumin was mostly shown to feel less fatigue than the other groups. On the other hand, Taeeumin appeared to feel more fatigue. In the biochemical analysis of blood, there was no significant difference between Sasang constitutions.

  • Based on a survey of citizens and data analysis on the environmental status of the Miyun Reservoir watershed, China, the environmental awareness of citizens residing in the watershed and the impacting factors are discussed. The contingent valuation method was used to evaluate the willingness of villagers to pay (WTP) for abatement of the rural domestic pollution and to assess the intensity level of the villagers' desire for improving environmental conditions in the Miyun Reservoir watershed. It was found that rural watershed residents had a fundamental cognitive understanding of the pollution status and protection measures of the Miyun Reservoir. However, based on the survey, local residents had only a small interest in their participation to improve the environmental status of the reservoir, despite their general attitude to protect the reservoir being very positive. Gender and family income were closely associated with the overall attitudes of the population. Public media are the most preferable means for conveying knowledge of environmental protection to people living in the watershed. Increasing the educational level, along with income, are the best ways to enhance the desire of the villagers to improve the environmental quality and management.

  • The prevalence of alcoholism among elderly population is reported to be high in rural areas in Korea. Chronic abuse of alcohol can lead to the development of vitamin B deficiency through inadequate intake, altered absorption and metabolism, and increased excretion. The present study was conducted to assess vitamin B1 and B2 status in seventeen alcohol dependent subjects who do not exhibit any clinical neurological symptoms. Vitamin B1 and B2 nutritional states were determined enzymatically by measurement of transketolase and glutathione reductase activities in erythrocytes, respectively. And dietary intakes of nutrients were determined by a 24-hr recall method. The mean percent activation of erythrocyte transketolase was significantly higher in alcoholics than in alcoholics than in control (p<0.05). The proportion of subjects with a low and borderline status of vitamin B1, was significantly higher in alcoholics than in control (p<0.05). The mean percent activation of erythrocyte glutathione reductase was not different between alcoholics and control. And the proportion of subjects with low and borderline status of Vitamin B2, was higher in alcoholics than in control (p<0.1). Vitamin B1 and B2 status were significantly decreased in alcoholics who were smoking cigarettes compared to non-smoking and non-alcoholic subjects(p<0.05). Whether vitamin supplementation improves the vitamin status of alcohol dependent subjects remains to be researched.
