본 연구는 미국 오레곤주의 水産業 特徵을 개괄적으로 살펴본 것이다. 먼저, 오레곤의 상업적 수산업을 역사적으로 살펴보면 2가지 주요한 契機가 있음을 알 수 있다. 첫째는 自給自足 次元에서의 연어생산을 수출품으로 변화시킨 연어통조림 생산기술의 발전이고, 둘째는 현대식 트롤어업이 도입된 점이다. 오레곤에서 주로 사용되는 어구·어법은 트롤, 채낚기, 연승, 통발, 형망 등이며, 생산어종은 연어, 게, 새우, 참치, 대구 등이다. 1995년 오레곤은 약 2억4

Foodborne diseases are serious problems throughout the world, because new pathogens have emerged. Nowadays many students eat school lunch provided by school lunch program. They are threatened by pathogens transmitted by foods. Many school children became victims of foodborne diseases. Most foodborne outbreaks were caused by mishandling foods at food service establishments. Temperature control is the most critical point of keeping the foods safe. In order to prevent foodborne diseases in schools, the managers in charge of school lunch program and officials in charge of food safety of local health department try to make sure that foods are out of danger zone of temperature. Prevention of cross contamination, and sanitization of raw foods and utensils are also emphasized by school lunch program managers and health officials.

The purpose of this study was to investigate the factors of food adaptation and the changes of food habit on Koreans residing in America. The subject was 89 Koreans residing in Knoxville, TN. The survey was undertaken from October to December of 1995. Demographic characteristics, food behavior, composite adaptation score(CAS), composition of Korean and American foods in 1 day, and frequence and preference changes of foods was determined. The results were summarized as fellows : The mean CAS for all subjects was 17.6 with individual scores ranging from 9 to 23. The CAS were significantly different in residing age, American friends, English speaking ability, eat with Koreans, American food experience before, American food experience now, breakfast type in weekday, breakfast type in weekday, and self-food habits change at p<0.05. No significant differences in CAS could be attributed to sex, marital status, children, and job. Food consumption patterns for breakfast was Korean style 58%, American style 39.3%. For lunch both style was almost same, and for supper Korean style was 78.2%. The intake of food most frequent was rice, and then Kimchee. The preference of Korean foods was increased, though the frequence was decreased. The preference and frequence of American foods were increased respectively.

This study was undertaken to determine factors associated with infant feeding practices among highly educated Korean mothers living in Texas, USA and local populations. In both groups, infant's birth order, maternal age, prenatal education, husband's attitude, mother's attitude and infant's taking a bottle to bed were not associated with infant's feeding patterns significantly. However, there was a significant difference in initiating time for introduction of supplementary foods between Koreans and Americans. Thus Korean mothers introduced supplementary foods earlier than American counterparts. Furthermore the infant's feeding method among all participants affected the time for introducing supplementary foods significantly. Though attitude of Korean mothers toward breastfeeding was slightly more positive than that of American mothers, the prevalence of exclusive breastfeeding in Koreans was much lower than that in Americans. It might be suggested that effective nutrition education program for Korean subjects should be developed to practice breastfeeding from positive attitude and knowledge. It might be also suggested that participation of prenatal nutrition education involving fathers should be encouraged for promotion of rates of initiation and duration of exclusive breastfeeding of mothers.

미국흰불나방(Hyphantria cunea Drury) 번데기의 휴면 종료에 미치는 탈피호르몬 20-hydroxyecdysone (20-HE)의 처리효과와 또한 호르몬처리로 유기된 휴면 후 성충발육 모습을 정상적인 성충발육과 비교하기 위하여 본실험을 수행하였으며, 그 결과 다음고 같다. 광주기 16L.8D와 에서 여러가지 다른 기간동안 저장했던 휴면번데기에 20-HE를 처리했을 때 가장 높은 휴면 종료율은 가장 오랫동안 처리된 군에서 나타났고 45일 동안 저장했던 휴면번데기에서 가장 낮은 종료율을 보였다. 우화에 필요한 기간은 저온()처리가간에 반비례하였고, 또한 저온처리기간이 길어질 수록 20-HE에 대한 민감도는 높아졌다. 번데기 휴면기간은 그들이 16L.8D 광조건에 처리되었건 혹은 지속적이 암조건에 저장되었건 간에 거의 같았고, 또한 저온처리없이도 성공적으로 성충이 출현하였다. 정상적으로 무화(휴면없이)하는 번데기의 산소소모율은 전형적인 U자 모양을 보였지만 20-HE에 처리된 휴면 번데기의 산소흡수량은 천천히 증가하다가 처리 후 14일에 급격히 증가하였다. 번데기 휴면은 성충조직을 형성하기 이전에 들어갔으며, 정상적으로 발육하는 번데기나 또는 20-HE에 처리되어 발육하기 시작하는 휴면 번데기 모두에서 성충조직 형성시기와 대사율이 증가하기 시작하는 시기는 일치하였다. 탈피호르몬처리로 발육을 시작한 휴면 번데기의 혈림프와 지방체에서 분리된 단백질종류는 모두 정상적으로 발육하는 번데기의 조직에서와 같았다.
