노년기의 활동 가운데 성(性)생활은 매우 중요한 활동임에도 불구하고 지금껏 우리 사회의 유교적 가치관과 노인에 대한 선입견으로 무시되어 온 것이 사실이다. 노골적인 성행위의 노출, 몇 번의 등급보류로 화제가 되었다가 결국 18세 이상 관람가로 결정된 "죽어도 좋아"라는 영화도 노인의 성에 대한 일반인들의 시각을 단적으로 보여주는 예이다. 이런 이유로 노인의 성은 은밀한 곳에서 노골적으로 표면화되어 노인들의 어린이 성추행이나 성범죄, 공원 내 불법매춘 등이 자주 매스컴에 오르내리고 있으며, 노년기의 성을 인정하지 않는 사회문화 분위기로 인해 현실적으로 고통 받는 노인들이 증가하고, 이는 노년의 만족스런 삶의 질 저하에 중요한 요인으로 작용하고 있다. 이와 같은 상황 속에서 만화콘텐츠는 노년기 성교육을 위한 가장 적절한 교구로 활용될 수 있다. 만화콘텐츠의 오락적 기능과 장르적 특성은 대상 노인들에게 성에 대한 이해를 보다 자발적이고, 쉽게 전달할 수 있으며 간접체험에 따른 동기 유발과 효과적인 활동을 위한 교구로서 기능할 수 있다.

Reproductive cycle with the gonadal phases, first sexual maturity, artificial spawning amount by the size and spawning interval of the hard clam, Meretrix lusoria were investigated by histological observations and morphometric data by artificial spawning induction. Meretrix lusoria is dioecious and oviparous. The reproductive cycle of this species can be classified into five successive stages: early active stage (January to March), late active stage (February to May), ripe stage (April to August), partially spawned stage (June to September), and spent/inactive stage (September to February). The spawning period was from June to September, and the main spawning occurred between July and August when the seawater temperature exceeds over $20^{\circ}C$. Percentage of first sexual maturity of female and male clams ranging from 40.0 to 45.0 mm in shell length was over 50%, and all clams over 50.0 mm in shell length sexually matured. Female and male clams ranging from 40.0 to 45.0 mm in shell length are considered to be two years old. Therefore, we assume that the hard clams of both sexes begin reproduction from two years of age. The mean number of the spawned eggs increased with the increase of size (shell length) classes. In case of artificial spawning induction, the number of spawned eggs from the clams of a sized class was gradually decreased with the increase of the number of the spawning frequencies (the first, second, and third spawnings). In the experiments of artificial spawning induction during the spawning season, the interval of each spawning was estimated to be 15-18 days (average 17 days).

Reproductive behaviors have evolved through severe inter-sexual competition. We have recently described a behavior in post-mated female Drosophila melanogaster that controls ejaculate retention and sperm storage, and is a possible mechanism by which females who have mated with several partners can choose which sperm that is stored and used for fertilization. This behavior can also regulate exposure of the female to harmful effects of male SFP that are present in the ejaculate. Our study identified the neural pathway functioning in the female brain that regulates this behavior. [BMB Reports 2015; 48(5): 241-242]

Objectives: Literature has shown the relationship between the use of harmful media and sexual behaviors among adolescents. Laws and regulations of violent and sexual mass media are getting stricter, but young children reported that they were still accessible to these harmful materials. It might be due to the development of new techniques in media delivery and new trends of game addict among Korean adolescents. Since there were very few studies on recent harmful media available to young children, the authors explore the usability of harmful media and identify related factors that can predict adolescent sexual attitudes and activities. Methods: This study was conducted secondary analysis using the internal data that were drawn from National Youth Committee's survey of adolescent harmful environment in 2007. The self-reported questionnaires were administered to 13,721 adolescents who were randomly selected based on strata of geography, school, and gender. Results: Adolescents accessed mostly to NC-19(No Children under 19) TV programs(35.8%) and AO(Adult Only) games(35.5%). Most of them reported that they did not have difficulty in the contact of these harmful media. The factors that can predict adolescent sexual intercourse are male adolescents, attending high school, not being satisfied with family life and school, contact with phone-advertising of sex, AO games and other online games, viewing adult videos, or reading adult books. Conclusions: When sex education is designed, an instructor considers not only students' demographic characteristics but also the strategies to deter the use of harmful media especially for game materials.

Purpose: The purpose of this study was to identify factors influencing depression in breast cancer patients. Method: A descriptive correlational study design was used. A convenience sample of 155 subjects was recruited from the outpatient for breast cancer patients at one hospital in Gyeonggi, South Korea. Body image was measured with the category of "Body image" from the EORTC QLQ-BR23(European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Breast cancer version) and sexual function was measured with category of "sexual function" from it. Depression was measured with Korean version of Beck Depression Inventory(BDI). Results: The mean score of body image was relatively low(M = 54.44, SD = 30.92), of sexual function was low (M = 24.82, SD = 22.50), and of depression was relatively low(M =14.90, SD = 8.00). Depression had a significant relationship with body image(r = -.363, p = <.001), however, there was no significant relationship between depression and sexual function(r = -.137, p = .103). In the regression analysis, depression was found to be influenced significantly by monthly income and body image, these variables explained 28.8% of the variance in depression(F = 4.662. p = <.001). Conclusion: It suggests that nurses need to take into consideration body image and economic status in management depression in breast cancer survivors.

A dolescence can be defined as the period between pubescence and physical maturity, and the passage through adolescence(age of 12-19) forms a critical period. Major developmental tasks of adolescence are construction of an emancipated identity, realistic ambitions, and reasonable ideals, and the further development of sexual and social identities. In early adolescence one struggles to adjust psychologically to the spurt in growth and tensions filled with sexual and aggressive impulses. There are reshuffling of peer groups due to differing rates of maturation, early adolescence crushes, sublimation of sexuality, and the resurgence of oedipal feelings. One reaches so-called period of formal operations in cognitive development. In mid-adolescence one struggles to overcome family attachments and controls, and it is a time marked by revolt and conformity. One has to overcome sexual repression while caught in reactivation of oedipal attachment. Peer groups gains in importance, and the peer group changes into a youth group that carries the youth culture. Late adolescence is a period of achieving an ego identity and capacities for intimacy. One has to prevent premature closure : Identity foreclosure limits both opportunity and the ability to guide one's own life. Gradually adolescent begins to have a loss self-centered and narcissistic orientation to one's sexual and affectional needs, and becomes involved in love relationship.

Spermatogenesis, the reproductive cycle, and the size at first sexual maturity in male Mactra chinensis were investigated by cytological and histological observations. The spermatozoon exhibits a primitive type morphology and is similar to those of other bivalves in that it contains a short midpiece with four mitochondria surrounding the centrioles. The morphologies of the sperm nucleus type and the acrosome shape of this species are cylindrical and modified cap-like, respectively. The spermatozoon is approximately $40-45\;{\mu}m$ in length including the sperm nucleus (about $1.46\;{\mu}m$), acrosome (about $1.20\;{\mu}m$) and tail flagellum. The axoneme of the sperm tail flagellum consists of nine pairs of microtubules at the periphery and a pair at the center. The axoneme of the sperm tail shows a 9+2 structure. The spawning period of this species lasts from June to September, and the main spawning occurs in July and August, when the seawater temperature is greater than $20^{\circ}C$. The percentage of individual male clams at first sexual maturity was 56.5% for those whose shell lengths were 35.1-40.0 mm, and 100% for over 45.1 mm. Accordingly, harvesting clams <35.1 mm in shell length could potentially cause a drastic reduction in recruitment, and a measure indicating a prohibitory fishing size should be taken for adequate fisheries management.
