Fishing efficiency of conventional bamboo traps and other traps for eel Conger myriaster, was investigated. The results are as follows: ). The best fishing efficiency was observed when the trap is inclined to the sea bottom with 20 ~ 30 degrees. 2. Plastic traps were better compared with bamboo traps in rigidity and fishing efficiency. 3. Using clips in attaching branch line to main line, the operating time was saved somewhat considerably.

Quantitative analysis of harmful Hg in edible bean sprouts was carried out by the Atomic Absorption Spectrophotometer (Perkin-Elmer Model 403). The samples studied as shown in Table 2. are edible bean sprouts (36) which wet·e collected from Gwangju area. It was investigated that the Mercury (Hg) content of edible bean sprouts was from 0.0098 ppm to 0.533 ppm (average 0.240). Mercury contaminated edible bean sprouts studied, was about 50 percentage of total samples.

It revealed that there were much differences to the extent of stress they have experienced during the delivery room practice between the nursing students(who experienced delivery room practice at an early stage) in C.Junior College of Nursing and nursing students(who experienced delivery room practice at a latter stage) in J. Junior College of Nursing(p＜.000). 3. In ten items of the stress that was confronted by nursing practice, they had much differences to the extent of stress perception for the students during the period of delivery room practice between each college(p＜.05). 4. In the four parts of the clinical practice except for adult nursing practice, they had much differences to the extent of stress according to whether they have their practical experience.

The research question of this study is, first, does the JUMP-UP program affect the reinforcement of the learning motivation of junior college students? Second, does the JUMP-UP program affect the self-learning efficacy of junior college students? As a result of examining the effectiveness by conducting a survey before and after participating in the JUMP-UP program, the JUMP-UP program showed statistically significant changes in all items of participating learners' learning motivation and self-learning efficacy. Through this, it can be seen that an intensive support program such as the JUMP-UP program is valuable as a support program suitable for improving the learning motivation and self-learning efficacy of vocational college students suffering from low academic performance.

The purpose of this study Is to prove the propriety of prolongation in educational term of department of food and nutrition at junior college in Korea in order to Improve the quality of dietitian by giving substantial education. The prolongation of educational term from two to three years is necessary to cultivate a more excellent dietitian because of the following three reasons. First, the freshmen in junior colleges are poor in basic scholastic ability which is needed for the study of nutrition science. Second, many new subjects which will support the new rollers of dietitian, in accordance with social changes, should be supplemented In curriculum. Third, the subject of spot-practice for dietitian should be established as a regular course in curriculum.
