This study was conducted to assess to the knowledge and educational needs of pregnant women relating to antepartum, delivery, postpartum periods, and to identify the variables which influenced their knowledge and educational needs. The study subjects were 282 postpartum women who had delivered fullterm normal babies without any complications. Data were collected from women those who were not more than two days after delivery at general hospitals, 3 maternal child health care centers and 4 midwife's offices in Pusan using questionnaire method from Feb. 1. 1991 to Mar. 20. 1991. The results of this study are as follows 1. Relating to the antepartum period, the knowledge about the time when the sex of fetus was fixed was low, and relating to delivery, the knowledge about the method reducing labor pain was low. 2. Relating to the antepartum period, the educational needs about child rearing was high, and relating to delivery, the educational needs about newborn baby were high. Relating to the postpartum period, the educational needs about emergency care of new born baby were high. 3. There were statistically significant differences in total educational needs by educational level(P<.01), duration of marriage (P<.01), and number of pregnancy(P<.05). 4. There were positive correlation between the total knowledge and educational level and negative correlations between the total knowledge and duration of marriage and age.

본 논문에서는 쉽게 즐길 수 있는 미니 게임과 같은 콘텐츠에서 이미지 검색 기술을 이용하여 게임에 적합한 이미지를 찾을 수 있고 또한 게임 난이도를 조절할 수 있는 방법도 보여준다. 본 방법에서는 영상처리 기술에서 내용기반 영상검색 방법 중의 색상과 질감 특징 값들을 추출하는 기술을 이용한다. 본 논문에서는 이를 이용하여 미니게임인 카드 짝 맞추기 게임에서 게임 안에 사용되는 카드 이미지를 자동으로 선택하게 한다. 이때 검색 기준이 되는 이미지(시드 이미지)의 개수를 조절하여 게임의 난이도에 적용 할 수 있는 것을 보여준다. 실험을 통하여 기존의 영상검색을 이용할 경우 게임에서 부적합 할 수 있는 이미지가 검색되는 문제가 나오는데 반하여 본 논문에서는 게임에 활용하기 용이한 이미지를 검색 할 수 있다는 것을 보여준다.

제주도와 완도에서 채집한 총 5종의 자생란의 뿌리에서 미동정 1종을 포함한 총 4종의 균을 순수분리하였으며, 추출한 DNA를 ITS지역을 증폭하여 분자적 동정하였다. 이중 3종이 Tulasnella속이었으며, 1종은 Sebacina vermifera로 일반적인 난균근균이었다. 제주도와 완도에서 모두 채집한 보춘화(Cymbidium goeringii)의 경우 제주도에서 채집한 뿌리에서는 Sebacina vermifera가, 완도에서 채집한 뿌리에서는 Tulasnella calospora가 분리되어 같은 종의난과 식물에서도 서식지에 따라 공생하는 난균근균이 다를 수 있음을 확인하였다.

The purpose of this study was to investigate chronic radiation effects on the basal cell of the rat tongue epithelium according to different irradiation timing. Forty-two female rats were devided into 5 experimental groups according to different irradiation timing and were irradiated single dose of 396cGy by MK cell irradiator using Cs-137. Experimental rats were sacrificed at the 2nd week, 4th week and 6th week after birth. The specimens were examined with light microscope and transmission electron microscope. The following results were obtained. 1. The first changes after irraditation were vacuoles. The vacuoles were chiefly observed in the cytoplasm, perinuclei area, and nuclei. 2. The most severe degenerative changes in the basal cell layer were observed in all experimental groups. ; cellular disarrangement, vacuole formation, widening of intercellular space, enlarged mitochondria & rER, and chromatin clumping were seen. 3. The cellular degenerative changes were most severe at the 4th week after birth in all experimental group, and the basal cell hyperplasia was seen at the 6th week in the most of experimental groups 4. The experimental groups 3 and 4 show more severe and more prolonged cellular degeneration than experimental groups 1 and 2, which were irradiated in pregnancy, and experimental group 5, which was irradiated after tongue maturation.

The leakage of toxic chemicals impact seriously on human being and environment, therefore during their treatment process, a proper management system is necessary to control their toxic effect. This study was designed to suggest the management regulation that supports business managers and facilities management. There are no extra regulation to control emergency accidents and terrors in chemical facilities. Developed countries like USA operate the management standards to control the toxic chemical and facilities according to their toxicity and processes. In order to solve this problem, we have analysed the advanced nations standard methods of security in chemical plants to study the new security management regulation which helps to prevent the chemical accidents. Especially, in USA, CCPS (Center for Chemical Process Safety), SVA (Security Vulnerability Assessment) and RBPSs (Risk-Based Performance Standards) of DHS (Department of Homeland Security) were invest I gated. On the basis of the results, we have suggested the application methods of the security and safety regulation in Korea.

최근 액체크로마토그래피는 의학상이나 천연물질 분리에 많이 사용되고 있다. 특히 혼합물에서 유용성분을 분취하기 위해서는 우선 분석용 크로마토그래피의 조업조건이 결정되어야 한다. 때문에 정확한 수학적 모델링과 시뮬레이션은 크로마토그래피의 발전과 디자인 과정에서 필요한 부분이다. 인하대학교 고 순도분리연구실에서는 크로마토그래피의 최적화를 목적으로 HCI 프로그램을 개발하였다. 이 과정에서 최소한의 실험으로 보다 정확하고 빠른 최적 조업조건을 HCI 프로그램을 이용하여 구할 수 있다. 즉 이론단수를 이용하여 체류인자를 예측하는 세가지 모델식으로부터 용출곡선을 계산할 수 있으며 분리도와 분리시간을 기준으로 최적 이동상의 조건을 계산할 수 있다.

Effects of chrysene on immune functions were studied in female BALB/c mice. When mice were treated po with chrysene for 7 consecutive days, the antibody response was suppressed dose-dependently. Chrysene induced the enzyme activities of CYP LA and 2B time- and dose-dependently. In ex vivo lymphocyte proliferation, chrysene inhibited splenocyte proliferation by LPS and Con A. Moreover, the numbers of $CD4^+IL-2^+$ cells were reduced by chrysene. In conclusion, chrysene-induced immunotoxicity might be mediated, at least in part, via IL-2 production, and caused by mechanisms associated with metabolic activation.

In this study, we examined the effects of self-efficacy and self-esteem on employment anxiety based on existing prior study and verified the moderating effect of academic stress between self-efficacy and employment anxiety, and moderating effect of academic stress between self-esteem and employment anxiety and the analysis result are as follows. The first result shows that self-efficacy and self-esteem negatively affect employment anxiety. Second, academic stress has not played a role of moderating in the relationship between self-efficacy and employment anxiety. As academic stress increases, employment anxiety increases. However, the regression analysis results confirmed that the academic stress can be an independent variable that explains employment anxiety. Finally, academic stress plays a role of moderating in the relationship between self-esteem and employment anxiety. This means that students with relatively high self-esteem are less likely to have employment anxiety than those who do not, and that increasing academic stress increases the employment anxiety of college students.

본 연구에서는 ERG의 하위요인들이 조직애착에 미치는 영향에서 자기효능감의 매개효과를 검증하는데 초점을 두었다. 이를 검증하기 위해 한국 내 기업에 근무하는 종업원을 대상으로 설문조사를 진행하여 실증분석을 진행하였으며, 연구결과 ERG의 하위요인들인 생존욕구, 관계욕구, 성장욕구가 모두 자기효능감에, 자기효능감도 조직애착에 유의한 정(+)의 영향을 미친다는 것이 밝혀졌다. 또한 자기효능감은 ERG 하위요인과 조직애착간의 관계에 있어서 모두 매개 역할을 한다는 것이 밝혀졌다. 이러한 연구결과를 바탕으로 실무적 시사점을 제시함과 동시에 향후의 연구 방향을 제시하였다.
