We characterized the resistances such as to waterlogging, Phytophythora and viruses in hybrids between Italian and Korean mother lines and screened them for complex resistances and agronomic traits to select elite multi-resistant lines for hybrid breeding. Resistance to waterlogging was selectable due to diversity of the resistance. Phytophythora resistance introduced from Italian lines could also be combined with resistance to other diseases and restoration abilities from cytoplasmic male sterility that has been maintained in Korean varieties.

This study is plan to show what kinds of problems we have and how we can overcome problems about occupational safety and health education and training system in Korea, Some features which advanced countries had were found and characterized as follows; First, advanced countries realized the importance of safety and health education on the role of preventing accident and they had varieties of training and education programs on the industrial safety and health for employer and worker. Second, there were many safety and health education programs and grants which especially focused to the small businesses. Third, they had also several programs to induce employer and worker's concerning about the safety and health education voluntarily, In conclusion, we introduced some inducing models, and proposed to revise contents of the education programs and to increase participation of other parties in safety and health education market so that could vitalize our safety and health education and training.

This study aimed to obtain fundamental data for demonstrating biodiversity of vegetation of East Asian alder (Alnus japonica) Forest Wetland of Heonilleung Royal Tombs. A total of 166 vascular plants (159 species, three subspecies, three varieties, and one cultivar) belonging to 132 genera and 59 families were found, accounting for 8.3% of 1,996 vascular plant species found in Seoul. Therophyte was the most common life-form of plants in Heonilleung Wetland. As for rare plant species, one Least Concern (LC) species was found. There were 15 floristic regional indicator species in the research area. Three of them belonged to floristic grades III and IV. This indicates that their habitats are discontinuous and isolated to some degree. Nineteen invasive alien plant species were found, most of which were introduced from North America after the year 1964 with a spread rate of V (widespread, WS).

Binder harvesters introduced to Korea were originally designed to be used for Japonica varieties which are highly resistant to shattering. In order to improve the performance of the binder to Indica varieties which are easily shattered and have shorter stem, mechanical modifications of the binder are inevitable. Shattering losses of the binder can be classified into two major parts; one incurred before and one after binding operations. The latter has been evaluated as great as the former. Previous studies indicated that the high discharge losses resulted from a great impact force of the discharge arm on the rice bundle during the discharge process. This study was intended to theoretically analyze the discharge mechanism of four-bar linkage. For this purpose, two commercially available binder harvesters having a four-bar linkage as a discharge mechanism were analyzed. Using the results from the motion analysis and the other structural constraints of the machines, they were modified and experimentally compared with the machines without modification to see whether any decrease in grain losses was obtained. The results obtained in this study are summarized as follows: 1. The path, velocity and acceleration of discharge arm were computer analyzed by vector analysis. Using results of the analysis and intrinsic constraints of the binder, discharge mechanism was modified to reduce the impact force on bundle by discharge arm in the range where the discharge performance was not deteriorated. This modification of the discharge mechanism could be done with an aid of four-bar linkage synthesis technique. As a result, average velocity and acceleration of the discharge arm during the discharge process were reduced respectively by 19 percent and 33 percent for binder A, and 17 percent and 35 percent for binder B. 2. Through the modification of the discharge mechanism, discharge losses of binder A were reduced by 42-56 percent for Milyang 23, Poongsan and Hangang chal, and discharge losses of binder B were reduced by 13-20 percent for Milyang 23 and Poongsan. 3. Discharge losses were decreased as the bundle size became larger and the size effect on the decrease rate appeared more significant in the binders with modifications than in those without modifications.

Varieties of literatures were reviewed in regard to the fundamental concept of day hospital, historical trends, the recipient of its care, facilities and personnel, therapeutic programmes and the follow-up care plans. Through the research the advantages of day hospital were highlighted in order to provide the reference for those who consider planning such health care institution. Since the introduction of the concept of day hospital and its implementation in 1930, many psychiatric patients world over are treated and cared. Patients with specific health problems ; alcoholism, acute or serious psychiatric disease, tendencies of humidor suicidal attempts, and with serious physical problems were excluded from the general recipient. Day hospital were annexed to the psychiatric hospitals in most in instances ; facilities, personnel, except nursing personnel, were shared. All therapeutic care were planned in daley, weekly programmes, and were focussed on socialization. The follow-up care were provided for those participating post- therapy club activities which were planned and introduced ahead. Many advantages of day-hospital care in contrast to the traditional hospitalization care were found: 1. The abrupt discontinuity of his family and other social role is prevented. 2. Therapeutic progress is faster. 3. Lessened economic burden to the family. 4. Behavioral regression is lessened and the lessened fear of hospitalization. 5. Less injury to the patients, self- respect, through lessened anxiety of hospitalization. 6. Incidents of secondary crisis believed to be existing in long term cases are decreased. 7. Therapeutic care implemented in freer atmosphere, better Patient-personnel relationships are created. 8. Varieties of group activities are Induced which enable faster recovery. 9. Patients could engage himself with social activities including getting job on part-time basis. 10. Rehabilitation of patient could be implemented.

1. "Kresek" 유발균주(K균주)는 품종에 따라서 발현에 차이가 있었으며 지상부 또는 지하부에 접종하여도 "Kresek"을 유발시킬 수 있었으나 대조균주(N균주)는 전연 유발되지 않았다. 2. 엽백의 도관직경은 밀양 23이 유신이나 통일보다 현저히 작았으며 이들간에 고도의 통계적인 유의차가 인정되었다. 3. 밀양 23의 즙액에서 K균주들은 N균주들보다 세균의 증식이 왕성하였으며 통일에서는 균주들간에 증식의 차이가 없었다. 4. 밀양 23의 즙액친서는 K균주의 Dead phase가 정종 9일째부터 N균주는 4일째부터 시작되었으며 통일에서는 모두 3일째부터 시작되었다. 5. 밀양 23즙액의 경우 pH 3.0-4.0 범위에서 다량의 침전물이 형성되었으나 동일의 증액에서는 극히 소량의 침전물을 관찰할 수가 있었다.

The purpose of this study is to provide basic data for the establishment of the management plan of Seoullo 7017 after analyzing the characteristics of immigration plants in addition to those introduced plants. The taxa number of plants appeared as 276 taxa including 82 families, 161 genera, 246 species, 1 subspecies, 22 varieties and 7 forms. Among them, immigration plants appeared 79 classification groups, including 32 families, 65 genera, 77 species and 2 varieties. Invasive alien plants appeared as 22 classification groups in 79 classification groups of immigration plants. The ratio of America origin plants, second period(1932~1960) in introduction time and the wide diffusion species is high. In June, the growth and occurrence time of the immigration plants was the highest by monthly the characteristics of the growth of the immigration plants, the immigration plants appeared mostly. In case of dormancy form among life-form, the therophytes(th), in the propagation form-radicoid form, the R₅(monophyte), in the propagation form-disseminule form, the gravity D₄(having no special modification for dissemination), and in the growth form, the erect form(e) was high. The various immigration plants appeared in green areas covered by Zoysia japonica and low Hedera helix densities. This study is the first flora study since Seoullo 7017 was opened in 2017. And so continuous flora monitoring is required for Seoullo 7017.

본 시험은 풋콩 채종기술의 기초자료를 얻고자 미카와시마, 화엄풋콩 및 석량풋콩의 3품종을 1992년 고냉지인 강원도 평창지역에서 생산된 종자와 일본 북해도에서 생산되어 1993년 춘계에 도입된 종자를, 1993년 4월 20일 수원 작물시험장에 채종하여 생육, 병해 및 수량들을 비교 검토한 바 그 주요 결과를 요약하면 다음과 같다. 1. 포장 출현율은 품종간에 차이가 있었고, 채종지간에는 국내고냉지 평창산 종자가 일본산 종자들보다 7% 정도 높았다. 2. 콩 생육경과중에 발생한 미이라병균에 의한 꼬투리 감염, 탄저병, 모자이크바이러스 및 노균병은 채종지간에 차이가 없었다. 3. 채종지간에 풋콩의 생육, 수량구성요소 및 수량성 차이가 없었다. 4. 이상의 결과로서 국내 고냉지에서 풋콩종자를 생산하면 일본산 도입종자에 비하여 출현율이 높고 생육과 수량면에서 저하되지 않는 양질종자의 생산이 가능하다.
