The purpose of this dissertation is to analyze the factors which university students feel as stress in their daily life and the correlation between these and their eating habits. The subject are students enrolled at 'H' university in Asan. There are 801 students who response for this research. We surveyed and analyzed the correlation between the life stress and eating habit of university students. It is analyzed that the objects suffered stress most by 'schooling' and 'job complication.' Surveying the general eating habit of university students, it is found that they do not eat meal regularly, i.e., 'average meals (40.9%)' and 'irregular meal(35.2%).' No significant difference was observed in the regularity of meals between sexes. When it comes to overeating or voracity, male students answered 'sometimes(77.6%)' or 'often(22.5%)', but female students answered 'sometimes(66.2%)' or 'often(28.2%)', which means that female students are more frequent in overeating or voracity. The frequency of eating snack is more than once a day 60.1% in female students and 47.3% in male students, which shows that the rate of female students is much higher than that of male students. Surveying the correlation between stress that male and female university students suffer and the regular meal, we found that both of them tend to eat meal irregularly if they are stressed. Comparing the stress for its factor, male students eat meal irregularly if they are stressed by 'schooling' and female students eat meal irregularly if they are stressed by 'figure.' Checking the correlation between stress and time spent for meal, it is found that while male students eat meal in a hurry when they are stressed by 'job affair', female students do so when they are stressed by 'home economy. Analyzing the correlation between frequency of snack and stress, both male and female tend to eat snack more frequently when they are stressed more. In general, males like the oily food more than male, but when students get stresses, females want to eat oily food than male. Analyzing the correlation between stress and preferential menu, males like green vegetables, sea food in the life get less stresses than others Females like a menu of meat get higher stress than others.

This study was to investigate purchase of women for commercial kimchi. Survey was carried out by questionnaire method that is target on 322 female over 20 age in Seoul area. The results of the study was that the way they get kimchi of women answered that they make it by themselves(63.3%). The reason of purchasing is they do not have enough time to make it at their home(43.8%) and its good taste(56.8%) result in their purchase. In the degree of preference about package material, prefer polyethylene(39.6%). Also respondents prefer purchasing poggi kimchi(63.4%) among other different types of kimchi. The promotion facts of purchasing commercial kimchi shows a high score in cold chain system package and specific kimchi development.

If you examine the Industrial Disaster Analysis Content that occurs every year in the small and medium enterprise, industrial disaster occurs because of manager's lack of safety and worker's unprepared safety education. Therefore effective safety education systems are needed to offer adequate knowledge and technology to the workers. On this research, to give an effective education way to decrease industrial disaster we administered to the workers who are in charge of 300 workplace in Incheon area to search actual condition of industrial disaster and to disclose a link between industrial disaster and industrial safety education. We put in effect on frequency study and examined x2 using SPSSWIN 10.0. On the research, the results shows that the industrial safety education and training are in effect regularly and the satisfaction are low. But the manager's satisfactions are high through safety education. So it shows that we need to find a way to put in effect safety education to satisfy the workers.

환경오염에 대한 관심이 높아지고 새롭게 고조됨에 따라, 에너지 관련해서도 대체에너지 이용에 관한 연구가 부각되고 있다. 신 재생에너지라고 불리는 대체에너지는 무공해, 무한정의 다양한 자연에너지의 특성과 이용기술을 활용하여 화석연료를 사용하는 기존에너지를 대체하는 에너지이다. 이러한 대체에너지 중 풍력 및 태양에너지는 그 자원이 무한정이며 환경에 미치는 영향이 거의 없이 이용할 수 있다. 두 발전시스템은 상호 보완적으로 연계된 발전시스템으로 통상적으로 조합되어 운용되어진다. 본 논문에서는 일정기간의 풍속, 풍향, 계절 등의 기상 조건의 변화에 따른 데이터를 분석하여 목포해안지역에서 경제적이고 효율적인 복합발전시스템의 적용가능성을 제안해 보고자 한다.

This study was carried out to determine occurrence and damage of golden apple snail, Pomacea canaliculata on water seeding area in Jeonnam province. The density of golden apple snail maintained high until October 2003, but quickly decreased from November. They overwintered only in a portion of the water canals but could not find in dried paddy field. They reproduced from May and June in the canal water and paddy field, respectively. Feeding time of golden apple snail on rice seedlings was 235.2 seconds, feeding length of that was 8.4 ㎝. When golden apple snail fed rice seedlings, the stem remain only 2.5 ㎝ from areal part which could not recover. The more density of golden apple snail, the faster feeding rate. Density and number of eggs laid of golden apple snail after overwintering was higher on bank around of paddy field than on middle of that. The percent of shell size after over wintering was higher in small (below 25 ㎜) than big (over 36 ㎜). But in case of Boseong area, the size was reverse because the soil has soft mud. The survival rate of overwintering golden apple snail was lower than that of breeding. They did not move when the temperature changed rapidly, but the temperature increased they start to move. They dead almost below -3℃. The damage of rice by golden apple snail in the direct water seeding was 20%. In machine transplanting, rice damaged only fore-end of leaf and recovered subsequently. When golden apple snail release in direct water seeding field, the percent of damage was 5.6% in immediately release plot. The later release, the lower damage.

From the surveys of 2005 and 2006 in Korea, Trissolcus nigripedius was found in four locations, i.e., Andong, Miryang, Namhae, and Suwon, and one of the major egg parasitoids of Dolycoris baccarum. T nigripedius was also found to parasitize two other soybean bugs, Riptortus clavatus and Piezodorus hybneri, from the field collection in 2005. Host acceptance behaviors of T. nigripedius consisting of drumming, oviposition, and marking were observed and compared on five species of soybean bugs. T. nigripedius showed the complete host acceptance behaviors on the eggs of D. baccarum, P. hybneri, and Halyomorpha halys. But T. nigripedius emerged only from the eggs of D. baccarum (96%) and P. hybneri (75%) after 24 hours of exposure. T. nigripedius did not mark on the eggs of R. clavatus and Nezara antennata during the observation of behavior, hence no egg deposition was made. However, T. nigripedius parasitized 20% and killed 30% of the eggs of R. clavatus when 24 hours were given for parasitization. T. nigripedius would be a potential biological control agent of D. baccarum and P. hybneri with ability of giving additional mortality on R. clavatus in soybean field.

본 연구는 광릉 지역의 활엽수 천연림과 도로 주변에서 서식지 구조와 조류군집의 특성을 파악하기 위해 2005년 10월부터 2006년 8월 사이의 기간 동안 수행되었다. 활엽수 천연림과 도로 지역의 서식지 환경은 매우 큰 차이가 있는 것으로 나타났다. 활엽수 천연림은 대경목의 비율이 높고 상층 임관이 잘 발달해 있는 반면, 도로에서는 소경목이 대부분을 차지하였으며, 상층임관의 발달이 적은 반면 하층식생의 피도가 높았다. 계절별 조사 결과 활엽수 천연림에서는 모두 37종의 조류가 관찰되었으며, 도로에서는 20종이 기록되었다. 4계절에 있어서도 활엽수 천연림 이 도로보다 관찰 종수, 개체수 및 종다양도에 있어서 모두 높은 것으로 나타났다. 또한 길드 구조에 있어서도 활엽수 천연림 지역에서는 수관층 및 수동(나무구멍)에서 먹이와 둥지를 얻는 조류들이 많이 관찰되었으며, 도로에서는 관목이나 지면을 이용하는 조류가 많이 기록되었다. 두 지 역은 인접해 있음에도 불구하고 조류 군집의 특성에 있어서 큰 차이를 보였다. 이러한 차이는 두 지 역 간 서식환경의 차이와 깊은 연관이 있는 것으로 판단된다.

In order to validate the meteorological and odor dispersion modeling methods, the measured meteorological parameters such as wind speed and direction and odor intensities were compared with those calculated from the models. The CALMET and CALPUFF models which were recommended by USEPA were used to predict the meteorological variable and odor concentrations. The average time of odor concentration was 10 mins. to consider instantaneous response nature of the odors. The results showed that model predictions were in good agreement with the measurements. It is expected that the modeling method presented in this paper will be useful to assess the impact of odors from industrial complex to near-by residential areas.

The aim of this study was to investigate the legally-designated malodorous compounds at the plant boundary areas of 5 plants expected to emit high odor intensities, as well as! complaint area at the Yeosu petrochemical industrial complex in Korea. The sampling was carried out during spring and summer of 2003 and 2006. The concentrations of ammonia, sulfur compounds (hydrogen sulfide, methyl mercaptan, and dimethyl sulfide) and aldehydes (acetaldehyde and propionaldehyde) emitted during 2006 were higher than those emitted during 2003, and the concentrations emitted during summer were higher than those emitted during spring at the plant boundary areas. It was thought that the concentrations of odorants in the complaint area had been directly influenced by the concentrations of odorants in the plant boundary areas as they showed similar patterns of concentration variations. While the concentration of TMA during 2006 was lower than during 2003 at the all sampling sites, the concentration of styrene during 2006 was higher than during 2003 at the all sampling sites. The sites showed high concentrationsof odorous compounds at the plant boundary area of the related chemical and petrochemical refinery plants.
