Recent reports on biotransformation of monoterpene alchols, aldehydes, acetates and epoxides are summerized. The studies have focused on stereospecific reaction of the functional groups of exogenous foreign substrates by foreign plant cells and micro-organisms. An another important aspect of research is the development of the immobilization technique for cells or related enzymes.

An Operating Experience Report(OER) has written about events and accidents happened at a Nuclear Power Plant(NPP). The purpose of publishing the OER is to prevent the similar event or accident repeatedly by spreading the experience of a single plant to other plants personnel. In this paper, it is analyses that the foreign NPPs' OERs on JIT published by the International Nuclear Agency(WANO, INPO, COG, BE). The analysis introduced in this paper is performed along with the various factors such as type of work, root-cause, and equipment. The root-cause analysis about the OERs shows that the Human-error is the major factor in foreign NPPs, but on the other hand equipment problem is the main part of the Domestic NPPs. The ratio of the foreign NPP's OERs on JIT according to the type of work was applied to KHNP-JIT developed nowadays for the first time in KOREA.

Each year, it seems inevitable that major accidents will occur on construction sites. Industrial accidents, sometimes involving foreign laborers, have been constantly increasing. Construction laborers have higher hazard rates and higher work intensity than other industries, which means that they experience more job stress, as a result of the subcontracting structure. Therefore, this study performed an influence factor analysis on job stress and its relevance to industrial accidents involving Korean and foreign construction laborers, and proposed its effectiveness with the job stress and construction accident management measures based on the results of those. A questionnaire to measure job stress was performed targeting Korean and foreign laborers, and the results were analyzed. The results of this study can be utilized as important reference materials in efforts to reduce the job stress of foreign laborers on construction sites, and can be expected to contribute to preventing construction accidents related to job stress in the future.

African swine fever (ASF) is one of the most complex infectious swine diseases and the greatest concern to the pig industry owing to its high mortality and no effective vaccines available to prevent the disease. Since the first outbreak of ASF in pig farms, ASF has been identified in 14 pig farms in four cities/counties in South Korea. The outbreak was resolved in a short period because of the immediate control measures and cooperative efforts. This paper reviews the ASF outbreak and the experience of successfully stopping ASF in pig farms in South Korea through active responses to prevent the spread of ASF. In addition, suitable changes to build a sustainable pig production system and collaborative efforts to overcome the dangerous animal disease, such as ASF, are discussed.

We have successfully used the low-pressure BioWare gene gun, developed for gene transfer in animal cells, for plant tissues. The BioWare device is easy to manipulate. Just 50 psi helium pressure was sufficient to transfer foreign genes into the aleurone layer and embryo of maize without causing tissue damage in the impact area. As shown by expression signals from invasive histochemical ${\beta}-glucuronidase$ (GUS) activity, the foreign reporter gene expressed well in bombarded tissues. This successful GUS-transient expression extends the application of this low-pressure gene gun from animal cells to plant tissues.

본 연구는 다수성 홍화 육종에 필요한 유전자원의 특성을 평가하여 교배모본으로 활용코자 원산지를 포함한 홍화 재배중심지에서 수집한 39개 계통을 대상으로 주요 농업형질의 재배적 특성을 비교하고 각 형질간의 상관 및 경로계수 등을 분석하였는 바 그 결과는 다음과 같다. 수집한 유전자원의 개화소요일수는 $83{\sim}100$일로 국내종 보다 만생인 계통이 많았다. 경장은 $75{\sim}165$\;cm$의 범위를 보여국내종 보다 국외 수집종이 대부분 장경이었고, 줄기 직경은 국외 수집종들이 국내종 보다 대부분 굵었다. 엽의 수와 면적은 국내종이 국외 수집종에 비해 많았고 큰 편이었다. 총분지수는 국외 수집종이 국내종보다 많았으며, 특히 3차 분지수의 범위는 $0{\sim}25$개로 큰 변이를 보였고 국내종의 경우는 3차 분지가 없었다. 화두수는 다분지 계통인 국외 수집종에서 많았다. 수량은 생육이 우수한 특성을 가진 중앙아시아와 미국에서 수집된 계통이 가장 높은 것으로 나타났다. 개화소요일수, 줄기직경, 분지수 및 화두수가 수량과 정의 상관관계를 보였다. 화두수와 총분지수의 직접효과가 높았으며 줄기직경, 엽수 및 2차분지수는 간접효과가 각각 컸다.

This research was studied to inverstigate the effect of plant mixtures and tackifibers on the vegetation of slope sites. 5 type plant mixtures(tree type, forest type, native herbaceous plant type, foreign herbaceous plant type, and cool-season turfgrass type) and 3 different tackifibers (Guar tackifibers, Polyarchrylamide tackifibers and Cellulose methyl starch) were treated with 3 replications on the experimented slope. The germination and coverage rate were high on native and foreign herbaceous plants and low on cool-season turfgrass, forest and tree types. We could notice that herbaceous plant types were effective on the vegetation of slope in the short term. Because tree or forest type vegetations similar to natural plant habitat, however, were preferable on slope vegetation in the long term, tree species of high germination rate should be selected in this experiment for tree or forest type slope vegetations. Tackifiber treatments increased the germination rate during the early treatment stage. However, the effect of tackifiber treatment on germination rate was decreased on the elapse of time. Guar tackifiber treatment was most effective on the vegetation of slope. As far as soil erosion control was concerned, all tackifiber treatments were effective compared to control.

To develop effective emission abatement strategies for eighteen coal-fired power plants located throughout Korea, power plant emission data and TAPM (The Air Pollution Model) were used to quantify the impact of emission reductions on primary $PM_{10}$ concentrations. TAPM was validated for two separate time periods: a high $PM_{10}$ concentration period from April 7 to 12, 2016, and a low $PM_{10}$ concentration period from June 1 to June 6 2016. The validated model was then used to analyze the impacts of five applicable power plant shut-down scenarios. The results showed that shut-down of four power plants located within the Seoul metropolitan area (SMA) would result in up to 18.9% reduction in maximum $PM_{10}$ concentrations, depending on synoptic conditions. A scenario for the shutdown of a single low stack height with highest-emission power plant located nearest to Seoul showed a small impact on averaged $PM_{10}$ concentrations (~1%) and 4.4% ($0.54{\mu}g/m^3$) decrease in maximum concentration. The scenario for four shutdowns for power plants aged more than 30 years within SMA also showed a highest improvement of 6.4% ($0.26{\mu}g/m^3$ in April) in averaged $PM_{10}$ concentrations, and of 18.9% ($2.33{\mu}g/m^3$ in June) in maximum concentration, showing almost linear relationship in and around SMA. Reducing gaseous air pollutant emissions was also found to be significant in controlling high $PM_{10}$ concentrations, indicating the effectiveness of coreduction of power plant emissions together with diesel vehicle emissions in the SMA. In addition, this study is implying that secondary production process generating $PM_{10}$ pollution may be a significant process throughout most regions in Korea, and therefore concurrent abatement of both gas and particle emissions will result in more pronounced improvements in air quality over the urban cities in South Korea.
