본 연구는 고체가연물의 초기 점화 및 화재성장과정에서의 발열량을 대형화재발열량계(large scale fire calorimeter)를 이용하여 정량적으로 측정하고 화재발생 초기에 화재성장특성 파악하고자 한다. 실험에 적용된 고체가연물 화재는 단일/이중 목재화재, 폴리프로필렌 소재의 쿠션화재, 목재 및 폴리프로필렌 소재의 카페트 화재이며 화재발달 단계에서의 화재성장특성을 시간 제곱 화재성장 시나리오와 비교분석하고 고체 기본가연물의 화재성장과정을 이해한다. 구획조건이 화재발열량에 미치는 영향을 파악하기 위하여 자유연소상태와 ISO-9705 화재실 내부에서 화재실험이 수행되었으며 화재성장특성과 최대발열량등을 비교하였다. 본 연구는 설계화재와 화재시나리오를 설정하는데 있어서 고체가연물의 발열량 데이터 및 화재성장에 대한 정보를 제공하고 공간조건에 따른 발열량 측정데이터의 신뢰성 분석을 위한 기초연구로 활용될 수 있다.

넙치양식의 급속한 발달과 더불어 넙치용 배합사료가 개발되어 이미 상품으로 생산·판매되고 있으나, 현장에서는 초기사료를 제외하고 여전히 생사료 위주의 사료공급이 주를 이루고 있다. 또한, 생사료의 사용으로 사료비가 양식전체 경영비의 50∼70%를 차지하고 있으며(Bai, 1996), 성장 위주의 과잉 공급에 의한 수질오염과 양식어류의 생리적 불균형으로 각종 질병의 발생 및 어체의 질적 저하 등으로 양식생산성이 저하되는 결과를 초래하고 있다. (중략)

The objective of this study was to examine maturation, fertilization and developmental rate of the in vitro-grown mouse oocytes, and to compare these results with those of oocytes grown and matured in vivo. The preantral follicles isolated from 12-day-old mice were cultured on Transwell-COL membrane inserts. After in vitro growth and maturation, 72.5 % of oocytes grown in vitro produced polar body which can be comparable to in vivo growth (70.5 %). However, the mean oocyte diameter of the in vitro group (69.6$\pm$2.1$\mu$m) was smaller than that of the in vivo group (73.3$\pm$3.0$\mu$m). The fertilization rate was significantly lower (p<0.05) in the in vitro group (76.5%) than in the in vivo group (90.2%), however, there was no difference in the percentage of monospermic and polyspermic oocytes between two groups. The capacities of in vitro grown ova to cleave and develop to blastocyst were (57.8 and 14.4%, respectively) significantly lower (p<0.001) than those of the in vivo counterpart (84.4 and 56.6%, respectively). Moreover, the mean number of cells per blastocyst was significantly lower (p<0.05) in the in vitro group (39.0$\pm$10.8) than in the in vivo group (60.5$\pm$12.5). Live young were produced from transferred 2-cell embryos derived from in vitro-grown and matured oocytes. In conclusion, the results show that in vitro-grown oocytes did not achieve the developmental capacity of in vitro-grown oocytes.

The present paper is a histological study of neurosecretory cells in the brain and the thoracic ganglion with the gonadal development in Palaemon serrifer. The reproductive cycle includes the successive stages of the growing period (February-March), the mature period(April-May), the ripe and spent periods(June-August) and the degenerative and resting periods(September-January). The neurosecretory cells are grouped into four types based on Matsumoto(1958) : A-,A'-, B- and E-cells. A- and A'-cells are $80-90{\mu}m,\;B-cell\;is\;30-40{\mu}m$ and E-cell is $10-15{\mu}m$. A- and B-cells are the positive to CHP and AF, while B-cell is the positive only to AF. The secretory grannules of a A-cell are transported to the axon, and at the same time they are discharged through the peripheral membrane. Of the four neurosecretory cells, A- and I-cells show the difference of secretory activity according to the gonad developmental process. In the female, A-cells show secretory activity for the ripe and spent periods, while I-cells show for the mature, ripe and spent periods. In the male, A-cells show secretory activity for the mature, ripe and spent periods, while I-cells show for the growing, mature, ripe and spent periods.

Purpose: Nurse educators can use film effectively to promote nursing students' motivation and indirect experiences. The purpose of this study was to develop a teaching-learning design using films based on Kolb's experiential learning model for understanding of child growth and development, and to evaluate students' satisfaction with cinenurducation according to learning type and content. Methods: Participants were seventy-four first year nursing students in the spring semester of 2013 at a private university located in Busan. In each class, participants watched film, participated in peer-to-group discussion and an educator's lecture, and wrote a composition based on Kolb's four learning stages. After class, participants filled out a questionnaire developed by the researchers. Results: Results showed a high satisfaction with cinenurducation regardless of learning type and content concerning child growth and development. Advantages of cinenurducation included it being "fun and interesting," "helpful to understand the characteristics of children," and "develop critical thinking through discussions." Disadvantages included "length of time needed," and "burdensome." Conclusion: Films are advantageous in that they provide indirect experience for nursing students. Selection of appropriate films and evaluation of learning goal achievements are important to maximize the effectiveness of cinenurducation.

This study presents "The Subject List for Developmental Bibliotherapy", for the purpose of offering selfdevelopment information to university students to assist them in identifying problems, and solving them while strengthening their egos. Theories relating to developmental psychology of young adult, results of analysing of student survey and successful examples of bibliotherapy subject lists from other universities have been applied for classifying of subject of this study. The four classes, are physical/mental development, social/emotional development, cognitive development and career development, have been classified into sub-classes and divisions in this study. With fixed career goals based on documents of developmental bibliotherapy, students can manage a more effective university education as early as their freshman year.
