The regional characteristics of summer precipitation in Korea are analyzed with the data observed in 66 stations from 1973 to 1997, using the cluster analysis method. In the phenomena of summer precipitation, the rain-rich regions lie in the south coast region, the northern part of Kyonggi Province, and Yongdong region. The monthly precipitation is mostly influenced by Changma fronts and cyclons in June, Changma fronts in July, typhoons in August, and all of typhoons, Changma, and cyclons in September. The increasing and decreasing trends of the monthly precipitation are equally divided with regard to both regional groups and monthly distribution in the cluster analysis. Especially such trends are considerably clear in the rain-rich regions. The increasing tendency is predominant in the northern part of Kyonggi Province and Yongdong region, while the decreasing trend and the periodicity are noted in the south coast region and Cheju Island. The variation of the monthly precipitation is shown to be great in the rain-rich regions, while it is not much associated with the rain-scare regions. Also, the variation is the greatest in September, while the least variation is shown in July.

This study was carried out to compare on the time of occurrence of 6 major rice insect pests [Lissorhoptrus oryzophilus Kusche, Oulema oryzae Kuwayama, Sogatella furcifera (Horvath), Nilaparvata lugens Stal., Cnaphalocrocis medinalis (Guenee), Mythimna separata Walker] in northern part of the Korean peninsula. Using growing degree days of the insects, we evaluated the number of occurrence generations and the time of occurrence. Over-wintering insects such as L. oryzophilus and O. oryzae showed different occurrence periods in northern regions. The occurrence period of the first generation adults was later in northeast regions than in Korean middle regions and more later both in northern alpines and in northern parts of east sea. In addition, the first adults of S. furcifera, N. lugens, C. medinalis, and M. separata occurred between June and early August. However, from late August to September, these insects showed the different occurrence periods in northern regions. Especially, the second adults of N. lugens were not occurred and the second to third generation adults of S. furcifera, C. medinalis, and M. separata showed similar occurrence properties. Based on these properties, the occurrence of major rice insect pests will be less in northeast regions, northern regions of east sea, northern inlands, and northern alpines of the Korean peninsula. However, comparing with their occurrences in northern regions of Gyenonggi and Gangwon provinces, the rice insect pests may show similar occurrence pattern in mid-korean mountains except for pyunggang and yangduk regions as well as in the southern and northern regions of Suyang-san.

This paper investigated and analyzed the status of students for jobs in textile industry for proposing the basic data for more effective labor supply to textile industry in northern region of Gyeonggi-do. The survey was conducted with 55 students in the middle aged class living in northern region of Gyeonggi-do who participated in the field practice education program related to industry business from April to June, 2013. The analysis results are described as below. For the satisfaction on the curriculum, 45.5% of the subjects showed the highest satisfaction on the education program. 65.5% desired the full-time employment in the textile business after the education. 78.2% of the subjects agreed that the education program for helping employment and recruitment in textile industry was the essential project in the current reality when there is a serious lack of field workers. Significant number of subjects answered that the education program should be implemented through the academy and business cooperation between the relevant departments in colleges and textile business. Although the subjects in this paper were very limited, the survey results would be important data to prepare the approach for improving the supply and demand of labor in textile business in the future as well as the starting point for a project to create new jobs for middle-aged women in the Northern region of Gyeonggi-do.

The purpose of this study is to derive spatial area(preventive zone) where the movement of livestock vehicles occurs frequently. For this purpose, this study used 6 periods facility entrance data provided by KAHIS. This data was converted into vehicle movement data between livestock facilities and aggregated into administrative district units. The R-mode factor analysis was performed on the constructed OD data, and the region extracted by the same factor was judged as one region. The results of the analysis are summarized as follows. First, the factor analysis of 6 periods data showed 16 ~ 18 factors, and the derived factors explained 63 ~ 68% of the total variance. Second, based on the factors that were derived, Jeonam coastal area, Jeonnam area, Jeonbuk area, Chungnam coastal area, Gyeongnam area, northern Gyeongbuk area, Yeongnam costal area were found to be stable, with little change over time. On the other hand, Chungbuk area, Gangwon area, Seoul metropolitan area are relatively volatile areas. Third, 13 areas were derived by combining data from six periods.

This study was to establish the floristic composition of northern region in Gyeonggi-Province area($126^{\circ}45^{\prime}-127^{\circ}37^{\prime}E$, $37^{\circ}31^{\prime}-38^{\circ}17^{\prime}N$). This work was investigated from April, 1988 to October, 2004. The flora of vascular plants of northern region in Gyeonggi-Province were consisted of total 2,030 taxa; 145 families, 656 genera, 1,611 species, 7 subspecies, 320 varieties, 1 subvarieties and 91 formae. Among them, Korean endemic species were composed of 46 families, 85 genera, 84 species, 35 varieties, 1 subvarieties, and 18 formae, total 138 taxa. The rare and endangered plants based on floral region indicated by Ministry of Environment were 416 taxa; V rank species 18 taxa, IV rank species 79 taxa, III rank species 111 taxa, II rank species 80 taxa, I rank species 128 taxa. Also the naturalized plants were 114 species, correspond to 39.7% of among total 287 species appeared in South Korea. the result of PCA, Gwangju mountain chain at northern region of Gyeonggi-Province has rich and diverse vascular plants, and there are many Korean endemic, rare and endangered plants. therefore Gwangju mountain chain must be the core axis in for conserving the plant biodiversity and richness.

제5차 전력수급기본계획상 2014~2016년을 전후하여 경기북부지역 5.2GW, 충남서해안 6.9GW 등 발전설비의 특정지역 집중건설이 예정되어 있고, 해당 발전출력의 원활한 전송을 위해 계통보강이 이루어져야 한다. 발전설비 및 송전설비의 보강집중에 따라 계통 고장전류 증가가 불파기한 실정이다. 특히, 우리나라 부하의 약 40%가 집중되어 있고 지역의 넓이에 비해 송전망의 밀집도가 매우 높은 수도권의 경우, 고장전류가 해당 변전소의 차단기 정격차단용량을 초과하는 문제로 인해 계통을 분리하여 운전되고 있는 개소가 전국 계통분리개소의 50%를 넘는다. 본 고에서는 향후 국내 전력계통의 고장전류 증가추이를 전망하고, BTB-HVDC의 적용 등 고장전류저감방안에 대해 논 하고자 한다.

The purpose of this study is to analyze the influence of the working-environment and job-satisfaction on the turnover intention of infant-care teachers. For this study, a survey was conducted on 200 infant-care teachers, who work in facilities of Northern Gyeonggi-do. The main results of this study are as follows: First, the turnover intention of infant-care teachers has no statistically significant differences by socio-demographic factors. Second, turnover intentions relate negatively to working-environment and job-satisfaction. More job-autonomy reduces the turnover intention and more job-conflict and job-burden increases the turnover intention. Third, the working-environment and job-satisfaction have influences on the turnover intention of infant-care teachers in the regression model. In conclusion, we need to improve the working-environment and to enhance job-satisfaction in order to reduce the turnover rate of infant-care teachers.
