In this study, we analyzed the phylogenetic characterization of root-knot nematodes (Meloidogyne spp.) in soils from fruits and vegetables greenhouses in Korea. Soil samples were collected from 12 greenhouse fields in which tomato, cucumber, watermelon, and Oriental melon were being cultivated. Meloidogyne spp. were detected in all the soil samples at an average number of $72{\pm}6$ nematodes/300 g of soil to $2,898{\pm}468$ nematodes/300 g of soil. Phylogenetic analysis using polymerase chain reaction-restriction fragment length polymorphism was attempted for the second-stage juveniles (J2) of Meloidogyne spp. collected from the greenhouse soils. Twelve Meloidogyne spp. from the greenhouse soils were classified into two groups by using HinfI digestion of mitochondrial DNA, resulting in 900, 410, 290, and 170 bp fragments (group A) and 900, 700, and 170 bp fragments (group B). Phylogenetic analysis based on mitochondrial DNA sequences (1,483-1,521 bp) showed that nine group A isolates were identified as Meloidogyne incognita (99.73-99.93%) and three group B isolates showed 99.54-99.73% similarity to Meloidogyne arenaria.

In urban planning, road facility is used not only for the transportation purpose but also for the utility line space purpose such as electrical, gas, tele communication, heating, water, sewer, and so on. However, since these utilities are built by many different groups, it becomes very difficult to communicate each other. Delay in one party can cause another party's schedule delay but they don't commuicate often. Also, some delay in utility work can cause frequent pavement cut. And, this will impact on construction cost, schedule delay, low quality, user complain and cost. This study developed spatiotemporal decision model to prevent prequent utility cut for mega project such as new urban development project. In addition, this study developed utility cut management system to manage utility cut schedule under pavement. Finally, developed system was applied to new urban development project and verified there effectiveness.

최근 들어 용수가격 상승과 갈수기 대비 대체용수 확보차원에서 폐수를 처리하여 공업용수를 재이용하는 사례가 증가하고 있다. 국내의 경우 단위 사업장에서 폐수재이용 시설을 설치한 사례는 비교적 많은 편이나, 정상적으로 가동하는 경우는 드문 것으로 조사되고 있다[1]. 이는 초기 시설 투자비를 줄이기 위하여 전처리를 소홀히 한 것이 가장 큰 원인으로 판단된다.(중략)

The purpose of this research is to investigate differences of governmental parts in social supports for unmarried mothers at home and those at facilities and to look at policy alternatives. Despite of the rising number of unmarried child rearing mothers in recent years, the governmental supports are not sufficient enough to aid even the most basic sustenance. The research on the governmental supports shows that unmarried child-rearing mothers at home were more aged, more employed, more educated and had children of more month ages than those at facilities. Single mothers at facilities were getting more governmental supports excluding crisis support and paternity test than those at home who appeared to be experiencing more difficulties. Based on the results from this research work, more realistic governmental policies are proposed to help a stable settlement of unmarried child-rearing mothers.

The purpose of this research is to practically figure out the relationship between Natural Forest service quality on user's satisfaction and demand to revisit. The results are as follows: First, the agent service quality, facility, accessibility, and cost as factors of the Natural Forest service quality. These are all influenced positively for visitor's satisfaction by priority of agent service> accessibility> facility> cost. Second, the agent service quality, facility, accessibility are all influenced positively on visitor's demand on revisit by priority of agent service> accessibility> facility. But the cost doesn't make an influence on revisiting. Third, the visitor's satisfaction made it as an influence on revisiting demand positively. These are the results for the research m service quality, user's satisfaction, facility, accessibility, and cost of the 5 Natural Forest over the Kyung-buk Province. We finally figured out the agent service quality is the most important factor to improve the quality of Natural Forest facility. We are sure about the improvement of the agent service quality which will make it successful.

Objectives: The purpose of this study was to classify frail and non-frail elderly and to investigate health promoting behaviors and perceived health status in the elderly according to the type of residency. Methods: This was a descriptive study. Data collection was performed from June 15th, 2009 to August 2nd, 2009. The subjects were selected at D city in Korea. Data was analyzed by descriptive statistics, $x^2$-test, and ANCOVA test with SPSS/Win 15.0 program. Results: 20.8% of the elderly living at home and 49.2% of those living in institution were frail. Frailty of the elderly living in institution was severer than those living at home. Non-frail elderly according to the type of residency showed higher scores of health promotion behavior and perceived health status than frail elderly. The elderly living at home showed higher scores of health promotion behavior than those living in institution. Conclusions: In the comparison study between the elderly living at home and institution, ratio of frail elderly among the elderly living in institution is high and health promotion behaviors are deficient as well. Frail preventive program for the elderly is needed to develop and apply in consideration of these findings.
