This paper tried to apply psychosocial factors in industrial safety research. Since Zohar's(1980) publication of safety climate in the field of safety research, this approach have been done by many researchers. Here, this paper reviewed the relationship between safety climate factors(safety rule, prevention, superior attitude, social support) and safety compliance, and the moderating effects of work condition, required skill and age. Based on the responses from 233 employees in Kangwon province industry, hierarchical regressional analysis showed that all safety climate factors(safety rule, prevention, superior attitude, social support) have positive relationship with safety compliance. Safety rule appeared to be more positively related with safety compliance, while work condition is more favorable and worker is older. But social support appeared to be more positively with safety compliance, while work condition is more unfavorable, and also prevention appeared to be more positively with safety compliance, while worker is more younger.

The objective of this study is to identify the individual characteristics and the elements of social capital hence a suitable design of social capital reinforcement can be proposed to promote a sustainable community-based mangrove management. The research conducted in three villages that were selected based on mangrove ecological differences in Lampung Province, Indonesia. Qualitative data was collected through field observation and in-depth interviews with key informants. The results showed that the population in the three villages dominated on productive ages, worked as farmers, and less educated (only a half of the population had fulfilled the basic education standard of Indonesia). The study results also indicated that the social capital in the communities showed minimum condition of interpersonal attachment and cooperation. This condition was derived from the attitude of the people who only took personal benefit without concerning to others' welfare. Many programs conducted by government to ensure the conservation of mangroves were project-oriented with minor participation of community. The minor participation might also contributed to the minimum of social capital in the community. To improve social capital, the communities should strengthen mutual trust based on mutual benefit to increase members' participation in mangrove activity.

Objectives: This study aimed to provide the high-quality clinical practice environment education to students by researching the social support, major satisfaction, and interpersonal ability of dental hygiene students, analyzing factors having influence on the clinical practice satisfaction, and then increasing the satisfaction with clinical practice. Methods: 312 students who have completed clinical practice among dental hygiene major of three colleges in Gyeonggi province were collected by convenience sampling from April 18th to April 27th 2016. Using SPSS 20.0, descriptive analysis, t-test, ANOVA, correlation analysis, and regression analysis were conducted. Results: The clinical practice satisfaction was correlated with interpersonal ability(r=0.383, p<.001), social support(r=0.239, p<0.01), subjective health condition(r=0.226, p<0.01), and major satisfaction(r=0.287, p<0.01). When interpersonal ability and social support were high, subjective health condition was good, and major satisfaction was high, the clinical practice satisfaction was also high. Conclusions: Based on the results, it would be necessary to develop operational reinforcing social support and interpersonal ability of dental hygiene students, and also to make efforts to increase the clinical practice satisfaction of dental hygiene students by establishing measures to increase their major satisfaction.

Some part of the route in KEPCO 765kV transmission line being constructed passes through a high mountain area which is 800m above the sea level (Taebaek, Sabuk area in Gangwon province). This area is the top part of Taebaek mountains corresponding to the backbone of korean peninsula and has lots of snow during the winter season because the winter seasonal wind gone up along the mountainside of Taebaek Mts. meets open air of the East sea. KEPCO has experienced 63 faults of T/L between 1968 and 1993 in this area, which is a very serious problem. Especially 154kV Hwang-Ji T/L fault in 1990, 2 was a unprecedented case which needs to be analyzed carefully to take proper measures. After reviewing ice and snow loading conditions and analyzing the fault of Hwang-Ji T/L, we're going to determine the revisement of ice and snow loading condition in this area to increase reliability of 765kV transmission line.

In this paper, we prove that if a metric measure space satisfies the volume doubling condition and the Hardy type inequality with the same exponent n ($n{\geq}3$), then it has exactly the n-dimensional volume growth. Besides, three interesting applications of this fact have also been given. The first one is that we prove that complete noncompact smooth metric measure space with non-negative weighted Ricci curvature on which the Hardy type inequality holds with the best constant are isometric to the Euclidean space with the same dimension. The second one is that we show that if a complete n-dimensional Finsler manifold of nonnegative n-Ricci curvature satisfies the Hardy type inequality with the best constant, then its flag curvature is identically zero. The last one is an interesting rigidity result, that is, we prove that if a complete n-dimensional Berwald space of non-negative n-Ricci curvature satisfies the Hardy type inequality with the best constant, then it is isometric to the Minkowski space of dimension n.

본 연구는 최근 세종시 조성으로 도시성격과 환경이 급변하고 있는 연기군 지역의 폐교를 대상으로 지역의 특성을 고려한 폐교의 활용을 모색하고 대안을 제시하고자 하였다. 이에 연기군 지역 폐교의 활용실태와 입지요인에 따른 시설의 물리적 요소 분석, 관리자 면담조사를 통하여 세종시 조성에 따른 환경 변화에 대응하는 폐교활용의 대안을 제시하였다. 첫째, 기존 농어촌지역의 폐교와 달리 연기지역의 폐교는 세종시가 인접해 있는 도시적 특성을 갖고 있다. 이에 따라 세종시 인근의 폐교는 세종시 교육시설과 연계한 교육연수원, 문화체험시설 등 교육프로그램과 연계한 시설활용이 바람직하다. 둘째, 세종시에서 상대적으로 접근성이 낮은 연기지역 폐교는 마을 단위의 공동체를 중심으로 활용해야 하며, 세종시 입주민과 함께 활용할 수 있는 요소를 고려해야 한다. 노인정, 마을회관, 공동창고, 보건지소 등 편의 및 커뮤니티 시설을 주된 용도로 활용하며 아울러 세종시 입주민의 이용이 가능하도록 주말농장, 농촌체험시설 등의 활용이 가능할 것으로 판단된다. 이는 도시와 농촌의 요구를 모두 수용할 수 있는 대안으로 주민의 직접참여를 유도하여 관리 부실을 방지하고 농촌과 도시의 교류가 가능한 대안으로 폐교활용의 새로운 가능성을 보여준다.

본 연구는 전라남도 장성지역의 한국잔디 재배지의 발생 잡초를 확인하기 위하여 2014년 9월(1차 조사)과 2016년 5월(2차 조사)에 전남 장성군 삼서면 일대에서 한국잔디 재배포장을 밭 토양과 논 토양으로 구분하여 발생잡초 분포조사를 수행하였다. 잡초분포 조사결과 밭 토양에서는 27과 66종(일년생 49종, 다년생 17종)으로 일년생잡초 74.2%, 다년생잡초 25.8%의 발생을 확인하였다. 과별로 보면 국화과(Compositae)가 19.7%로 가장 많이 발생하였고, 그 다음으로 벼과(Gramineae) 13.6%, 콩과(Leguminosae) 10.6% 순이었다. 논 토양에서는 22과 69종(일년생 53종, 다년생 16종)으로 일년생잡초 76.8%, 다년생잡초 23.2% 비율의 발생을 확인하였다. 과별로 보면 국화과(Compositae)가 18.8%로 가장 많이 발생하였고, 그 다음으로 벼과(Gramineae) 14.5%, 사초과(Cyperaceae) 7.2% 순이었다. 밭 토양의 1차 조사에서는 벼과의 바랭이(8.49), 2차 조사에서는 괭이밥과의 괭이밥(7.26)이 가장 우점하였고, 논 토양의 1차 조사에서 국화과의 개망초(9.52), 2차 조사에서는 닭의장풀과의 닭의장풀(5.08)과 벼과의 뚝새풀(5.08)이 가장 우점하는 잡초종으로 확인되었다. 잡초발생 현황을 조사시기와 토양조건을 구분하여 비교한 결과 논 잡초와 밭 잡초가 혼생하는 것으로 확인되었다. 조사시기 또는 토양조건에 상관없이 공통적으로 발생하는 초종의 비율이 49.2%로 비교적 높게 나타났다. 따라서 한국잔디 재배지에서 제초제를 이용한 효율적인 방제효과를 위해서는 재배토양에 상관없이 논 잡초와 밭 잡초를 모두 잘 방제할 수 있는 약제를 선택해야 할 것으로 판단되었다.

It is very important to investigate the sanitary chemical conditions of farmwaters used for cattle breeding in the dairy farms. For this purpose we examined pH, KMnO4 consumption, total hardness, chloride, sulfate, NH3-N, NO3-N, fluoride, lead, iron, manganese, cadmium, copper, zinc and chrome in the farmwaters sampled 2 times(spring and summer)in Choongcheongnam and Kangwon Province. The pH of farmwaters in Choongcheongnam and Kangwon Province was 6.49$\pm$0.09, 6.70$\pm$0.06, total hardness 90.21$\pm$7.07, 64.53$\pm$6.38 mg/ι, consumption of KMnO4 4.13$\pm$0.62, 4.34$\pm$0.26mg/ι, NO3-N 6.51$\pm$0.55, 3.61$\pm$0.58 mg/ι, chloride ion 20.51$\pm$1.99, 5.41$\pm$1.36 mg/ι and sulfate ion 6.61$\pm$1.02, 7.28$\pm$1.30 mg/ι, respectively. But NH3-N was scarcely detected. Fluoride, iron, lead, cadmium, zinc, manganese and chrome were not detected from the tested farmwaters. There was high significance between each other in total hardness, NO3-N, chloride ion and sulfate ion. There was regional and seasonal significance in only NO3-N but only regional significance in total hardness and chloride ion.
