sndA 유전자(AN3911) 하위에 위치하고 있는 GAL4형 전사인자를 암호화하는 유전자(AN3912)에 대해 분석하였다. 이 전사인자는 Zn(II)2Cys6 binuclear cluster DNA-binding domain 과 전사활성부위를 모두 가지고 있는 전형적 진균 특이 전사인자로서 해당 유전자는 gtfA (gal4 type transcription factor)라 명명되었다. 이 유전자의 ORF는 762개의 아미노산으로 구성되어 있고 3개의 intron이 그 안에 존재하였다. gtfA 유전자의 결실돌연변이는 무성포자생성이 감소하고 대신 유성생식기관이 증가하는 형질을 보여주었다. 과다발현균주는 높은 포도당 농도가 주어지면 유성생식이 늦어지는 형질을 나타내었다. gtfA 유전자는 영양생장 후반부와 유성분화 초기단계에서 높은 발현량을 보이고 전생활사를 통해 비교적 일정하게 발현되었다. gtfA의 전사는 일부 유성(NsdD, VeA) 및 무성(FluG, FadA, SfaD) 분화 조절자들에 의해 크게 영향을 받지 않았다. 반면 GtfA는 nsdC 유전자의 발현을 억제하는 것으로 나타났다. 종합하여 볼 때, GtfA는 분화 결정시기에 nsdC의 발현을 억제함으로써 유성분화보다는 무성분화로 유도되도록 조절 할 것으로 추정된다.

우리나라에 분포하는 멧토끼 (Lepus coreanus)의 성판별을 위한 분자 표지자를 개발하기 위하여, X, Y 염색체간 상동인 ZFX와 ZFY 유전자들의 성별 이형성에 초점을 맞추어 본 연구를 수행하였다. ZFX와 ZFY 유전자의 인트론 7 영역은 멧토끼의 암수가 구분되는 증폭 양상을 나타내었다. 인트론 7의 길이는 각각 ZFX에서 538, ZFY에서 233-bp로 확인되었다. 특히, ZFX의 인트론 7에서는 RNA-매개성 전위인자 중 한 종이며 토끼의 유전체에서 빈번하게 관찰되는 CSINE2와 유사한 반복서열이 발견되었다. 반면, 반복서열은 ZFY의 인트론 7에서는 관찰되지 않았다. ZFX와 ZFY 유전자의 인트론 7에서 확인된 길이의 차이에 근거하여 중합효소연쇄반응 기법을 이용한 유전자 성판별을 수행하였다. 시험에 이용된 모든 DNA시료들은 ZFX에서 증폭된 공통의 밴드를 가지고 있었다. 이에 반해, 멧토끼 수컷 DNA들은 각각 ZFX와 ZFY에서 증폭된 두 개의 구분되는 밴드들을 나타내었다. ZFX-ZFY 유전자·성판별 결과는 표현형 성별 정보뿐만 아니라 수컷-특이적인 SRY 유전자의 증폭양상과도 일치한 결과와도 정확히 일치하였다. 이상의 결과들은 멧토끼에서 ZFX와 ZFY의 인트론 7 영역간의 성별 이형성은 유전자 성판별을 위한 유용한 유전자 표지자가 될 것으로 사료된다.

본 연구는 근로자의 신체적, 정신적 피해의 요인을 파악하며 기초자료를 제공하고자 시작되었다. 제5차 근로환경조사 원시자료를 이용한 분석연구이며, 연구는 50,205명을 대상으로 근로자들의 성별, 언어폭력, 모욕, 성희롱, 성적관심, 왕따 괴롭힘이 근로환경 만족도에 미치는 영향을 분석하였다. 대상자의 성희롱 가해자는 직장동료(83.6%)가 대부분을 차지하였으며 왕따 괴롭힘과 성적 관심에 의한 피해는 남성보다 여성이 더 많이 경험한 것으로 확인되었다. 모욕과 언어폭력은 근로환경 만족도를 저하시키는 요인으로 확인되었다. 본 연구를 토대로 근로자의 영향요인을 고려한 프로그램으로 근로자의 근로환경 만족도 향상뿐 만 아니라 생산성과 Work-life balance의 향상을 기대해본다.

Gonadal development, reproductive cycle, gonad index, meat weight rate, and first sexual maturity of the top shell, Omphalius rusticus were Investigated monthly by histological observations. Specimens were collected from the west coast of Korea during the period from January to December in 1999. O. rusticus is dioecious and oviparous. The gonad is widely situated on the surface of the digestive g1and located in the posterior spiral meat part in the shell. The ovary and the testis were composed of a number of oogenic follicles and several spermatogenic follicles, respectively. Ripe oocytes were approximately 120-130 $\mu$m in diameter. The meat weight rate peaked in June (27.7%), and then rapidly decreased in September (19.5%). Monthly changes in the gonad index in both sexes reached the maximum in June, and then sharply decreased in September. Percentages of first sexual maturity of female and male snails ranging from 9.0 to 9.9 mm in shell heights were 58.3% and 54.5%, respectively, and 100% in those over 11.0 mm in both sexes participated in reproduction. Reproductive cycle of this species can be categorized into five successive stages: in females, early active (October to April), late active (December to June), ripe (April to September), spawning (July to September) and recovery (September to January): in males, early active (November to March), late active (December to June), ripe (April to September), spawning (July to September) and recovery (September to December). Gonadal development, gametogenesis, reproductive cycle, and spawning were closely related to the seawater temperature.

Purpose: This study was designed to identify nurses' perceptions and educational intentions regarding natural childbirth control (NCC) methods. Method: The participants were 313 nurses working at three general hospitals in Seoul. They were asked to complete a questionnaire composed of scales measuring knowledge and perceptions childbirth control methods, awareness of bodily changes in ovulation phase, perceptions of fetal life, which were developed by the author. Also, Chang's (2002) Sexual Autonomy Inventory was utilized. The data were analyzed by the SAS program. Results : Methods of condom and rhythm were considered to be more useful for childbirth control than other methods. Only 34-54% of them knew exactly about the NCC methods using menstrual cycle, body temperature, and mucus. The mean scores of sexual autonomy and awareness of bodily changes in ovulation phase were 3.8 and 3.4 out of 5, in respect. Educational intention was different statistically by the age, marital status, future intention to use NCC methods, and perception of educational need for NCC methods. Conclusion : Nurses' perceptions and educational intentions regarding NCC were low, especially in nurses who were married. It is recommended to encourage nurses to learn NCC methods for clients education.

Gonadal development, gametogenesis, reproductive cycle, and first sexual maturity of Reishia clavigera were investigated monthly from July 1998 to June 1999 through cytological and histological observations. R. clavigera had separate sexes, and was an internal fertilizer. The ma1e penis was located near the two tentacles. The ovary and testis were composed of a great number of oogenic lobules and spermatogenic tubules, respectively. The size of ripe oocyte ranged from 130 to 140 ${\mu}$m in diameter. The peripheral cytoplasm of the germinal vesicle of the ripe oocyte in many cases were surrounded by smaller yolk granules, while the eccentric cytoplasm was occupied with larger ones. The reproductive cycle of R. clavigera could be classified into five successive stages: early active, late active, ripe, spawning, and recovery. Spawning of females occurred from early July to August when the seawater reached above 24.8$^{\circ}C$. Spawning of males occurred from early June to August in the water above 22.8$^{\circ}C$. Minimum size for sexual maturity of both sexes was above 10.0 mm in shell height. Each egg capsule was a cylinder or spindle in shape, 4-6 mm in length and 1-2 mm in width. Colors of newly spawned egg capsules showed yellowish white or pale yellow, while those with veliger larvae showed pale black, and released larvae or dead egg capsules showed black violet. The fecundity in an egg capsule ranged from 70 to 91 eggs (mean＝80.28 eggs).

The purpose of this study is to understand the subjective experiences of institutionalized, unmarried teenage mothers. Through structured in-depth interviews, we have explored their feelings and values about pregnancies, sexual behaviors, contraception, babies, adoption, babies' fathers, and their own families. Ten unmarried teenage mothers, who residing in welfare facilities located in Seoul, Kyonggi, and Kangwon, were interviewed. It turned out that the teenage mothers we interviewed had given little to no thought about pregnancy and contraception at the time conception. They contradicted themselves on a number of points. Since most of the fathers denied their responsibilities, the mothers were angry with the babies's fathers. At the same time, they felt humiliated about having to inform the babies' fathers about their pregnancy. They felt simultaneously sorry and resentful toward their own parents. They cared about their babies, yet they regretted not having had an abortion. Listening to what these mothers say will help the professionals and researchers to explicate certain preconceptions and prejudice about them, and to improve policies and services for them.

Purpose: Sexuality is a fundamental element of human life and is closely related to mental health. This study was conducted to understand domestic research trends on gender, mental health, and psychological well-being through an integrated review. Methods: Through four domestic databases, 15 papers were finally selected using the search terms 'sex', 'mental health', and 'psychological well-being'. Results: Fifteen papers have been published since 2000 and 10 documents have been published since 2010. A majority of the studies were basic research and reviews, and these included four qualitative studies. Depending on the subject, we classified five articles into three themes by the developmental stages (youth, married women, and the elderly), eight sexual minority studies, and two other studies (right to sexual self-determination, and dating for people with disabilities). Conclusion: A more open social concern and approach to sex, the most basic human need, is warranted. The field of nursing practice requires more attention.
