본 연구는 그룹홈 거주 중고령 발달장애인의 생활만족도에 영향을 미치는 요인을 분석하고 있다. 이를 위해 서울시 그룹홈 종사자들의 대리응답조사와 발달장애인 당사자 대상으로 한 심층면접조사를 병행하였으며, 최종적으로 387명의 자료가 확보되었다. 분석결과에 따르면, 청년기 발달장애인들의 생활만족도는 직원 직무수행 수준이 높을수록, 지역사회활동 수준이 높을수록 높게 나타났다. 이에 비해 중고령 발달장애인들의 생활만족도는 활동피로감 수준이 낮을수록, 이용자 선택 수준이 높을수록, 직원 직무수행 수준이 높을수록, 사회활동 참여수준이 높을수록 높게 나타났다. 그룹홈의 직원직무수행은 청년기와 중고령기에 공통적으로 유의하지만, 활동피로감, 이용자 선택, 사회활동 참여 등은 중고령기에만 유의한 것으로 정리된다. 이상의 결과는 그룹홈 중고령 발달장애인의 생활만족도 증진을 위해서는 다른 연령층에 대비되는 이들의 차별적 욕구를 고려한 특화 건강지원, 사회활동지원, 서비스 공급노력이 요구된다는 점을 보여준다. 이는 그룹홈 발달장애인 당사자의 견해에 기초한 생활만족도를 증진하려는 노력과 그 맥을 같이한다. 본 연구는 향후 조기노화의 위험이 높은 다운증후군장애인, 뇌성마비 및 지적 중복장애인 등을 대상으로 이들의 차별적 욕구와 현황을 살피려는 연구로 확장되기를 제언한다.

Organizational culture has been, by and large, regarded as one of the most significant factors to manage organizations. Especially the understanding of empowerment is pivotal, leading to explain organizational cultures. For hospital workers whose services are closely related to quality and performance of their hospitals, empowerment is now called upon more than ever before. This study is intended to investigate the relationship between organizational culture types and hospital workers' empowerment levels. The data were collected from 589 hospital workers at one university hospital and two general hospitals using the self reported questionnaire from Jan.9 to Jan.20 in 2004. The findings were as follows: 1. Empowerment levels were significantly different among the four organizational culture types. Developmental culture group showed the highest empowerment score(3.74), and next were group culture(3.64), rational culture(3.62), and hierarchial culture(3.46). 2. There was a significantly positive correlation between group culture and empowerment(r=.298, p<.000), between developmental culture and empowerment(r=.295, p<.000). But there was not a significantly correlation between hierarchial culture, and between rational culture. 3. According to the multiple regression analysis, self-esteem(${\beta}$=.417, p<.001), position (${\beta}$=-.190, p<.001), self-control(${\beta}$=.185, p<.001), and age(${\beta}$=.169, p<.01) were significant among general properties for organizational empowerment. As for organizational cultures, developmental culture(${\beta}$=.165, p<.001), group culture(${\beta}$=.099, p<.01), and rational culture (${\beta}$=.063, p<.05) were significant other than hierarchial culture. In conclusion, it is necessary to promote group culture and developmental culture to enhance hospital worker's empowerment level, and this article elucidates that understanding the organizational culture embedded in each organization is important for efficient management of organization.

The aim of this study is to investigate the effects of ambient thermal environments on the development of swallowtail butterflies (Sericinus montela Gray). Developmental durations and survival rates of S. montela were examined at two crucial developmental stages, embryonic and larval development, at varying temperatures ranging from $15^{\circ}C$ to $35^{\circ}C$. As expected, our results indicated that increasing temperatures decreased the developmental duration and survival rate of the eggs. However, the larvae and pupae showed maximum survival rates at $20.0^{\circ}C$ and $25.0^{\circ}C$, and the represented durations were similar to those of the eggs. Larval development was stage-specific, revealing that the fourth and fifth instars at the later stages were more susceptible to temperature variation. When considering both parameters, the optimal development of S. montela occurred within the temperature range of $20.0-25.0^{\circ}C$. The lower threshold for the complete development of S. montela from eggs to eclosion of adults was calculated at $10.6^{\circ}C$ by linear regression analysis. The estimated value is similar to that of other endemic insects distributed in temperate climate zones, which indicates that S. montela belongs to a small group of swallowtails adjusted to low ambient temperatures. From the results, we predict that the full development of S. montela could be achieved within the temperature range of $17.5-30.0^{\circ}C$. Embryonic development ceased at both test temperature extremes, and no further larval development proceeded after the third instar at $35.0^{\circ}C$. These results suggest that embryogenesis can be significantly influenced by slight variations in the ambient thermal environment that fall below the optimal range.

포도 '캠벨얼리'의 발아기 예측을 위해 자발 휴면 타파 이후 발아일까지의 발육 속도(DVR) 계산식을 도출하였다. 항온 실험에서 계산한 DVR은 온도에 대하여 지수 함수식 또는 선형 함수식 모형으로 증가하는 경향이며 DVR 기울기는 0.0019 내외였다. 포도 DVR 계산식은 대기 온도에 대하여 $DVR=0.0249+0.0020e^{0.1654x}$ 또는 DVR = 0.0019x + 0.0187이었으며, DVR 계산식에 일 평균 기온을 대입하여 계산한 예측 발아일의 실측 발아일에 대한 적합도 검정 RMSE 값이 4일 이하로 작았다. 또한 DVR 계산식에 시간별 온도 자료를 대입한 경우에는 일 평균 기온 자료를 사용한 경우보다 오차 값이 작았으며 이때 RMSE 값은 3일 이하였다. 이는 본 연구에서 계산한 DVR 계산식이 포도 발아기 예측에 유용한 예측 값을 제공할 수 있다는 것을 의미한다.

Golden hamsters reproduce in a limited time of a year. Their sexual activities are active in summer but inactive in winter during which day length does not exceed night time and environmental conditions are severe to them. The reproductive activities are determined by the length of light in a day (photoperiod). Melatonin is synthesized and secreted only at night time from the pineal gland. Duration of elevated melatonin is longer in winter than summer, resulting in gonadal regression. The present study aimed at the influences of continuous melatonin treatments impinging on the gonadal function in male golden hamsters. Animals received empty or melatonin-filled capsules for 10 weeks. They were divided into long photoperiod (LP) and short photoperiod (SP). All the animals maintained in LP (either empty or melatonin-filled capsules) showed large testes, implying that melatonin had no effects on testicular functions. Animals housed in SP displayed completely regressed testes. But animals kept in SP and implanted with melatonin capsules exhibited blockage of full regression by SP. These results suggest that constant release of melatonin prohibits the regressing influence of SP.

Purpose: The purpose of this study is to explore the validity of the application of the Denver II developmental screening test to Korean children. This screening test. which was developed and standardized in United States. was designed to screen for developmental delay in Korea. and to compare the levels of development of Korean children with the development of children from the U.S. Method: Quota sampling. NP To facilitate field sampling. the age range used from 0 to 6 years old. was split into 10 different age groups. Sample size was estimated according to residence. 1.054 children were recruited from Seoul's metropolitan. urban and rural areas. NP To fill the quota established. the Recruitment and testing of children was done at public health centers, pediatric outpatient clinics of general hospitals and a child care center. The 25, 50, 75 and 90 percentiles were identified by using logistic regression analysis and were calculated as norms. The items in which the ages of both 50 and 90 percent passing differed more than 20 percent by the calculation was identified for comparison. NP Result: There were significant differences found in 45 items between Korean children and the children from the City of Denver as it relates to age differences. 90% of the sample passed items among 125 items from 4 sectors, e.g., personal- social. fine motor adaptive, language, and gross motor sectors. Korean children were found to be advanced in 9 items, whereas there were significant differences found in 38 items in our comparison of the two countries for age differences when 50% of sample pass items. Korean children were found to be advanced in 16 items. NP Conclusion: The result showed that there was a discrepancy in the developmental norms. It could be explained by the differences in the developmental environment. including child rearing patterns and ethnicity. Therefore, a restandardization of the Denver Screening Test is necessary as it relates to its application on Korean children. This restandardization is necessary in order to avoid both under and over-referrals of children with developmental abnormality. The modification of items in the language sector is especially suggested.

This study was performed to investigate the temperature-dependent development, longevity and oviposition of an indigenous larval parasitoid, Meteorus pulchricornis, on tobacco cutworm, Spodoptera litura. M. pulchricornis were reared at nine constant temperatures between 15 and $35^{\circ}C$. The developmental times of each three developmental stage decreased from 38.7 to 16.3 d between 15 and $30^{\circ}C$. However, M. pulchricornis showed longer developmental time at $32.5^{\circ}C$ (9.5, 7.7 and 17.2 days for each three developmental stage) than at $30^{\circ}C$ (8.9, 7.3 and 16.3 days for each three developmental stage). Immature M. pulchricornis could not develop any more at $35^{\circ}C$. The lower developmental threshold estimated by linear regression equation for the egg to cocoon, cocoon to adult emergence and egg to adult emergence were 5.1, 4.6 and $4.5^{\circ}C$. The thermal constant for each of the three stages were 217.2, 176.2 and 403.8 degree-days, respectively. When no food or 50% honey solution as a food source is provided for M. pulchricornis, the parasitoid survived for 8.3 and 55.9 days at $25^{\circ}C$, respectively. M. pulchricornis females laid 5.2 eggs daily and total of 131.6 eggs at $25^{\circ}C$ until it died. Peak age-specific fecundity was observed on $14^{th}$ day (9.6 cocoons) after parasitoid emergence and gradually decreased thereafter.
