The attitudes toward release for adoption of 130 teen-age unwed korean mothers were studied with the use of the donnelly and Voydanoff(1991) scale of attitudes about release for adoption and expectations regarding parenthood. Data were analyzed by t-test. While there were no socio-demographic differences between the 10.7% of mothers who planned on keeping their babies and the 89.3% who planned on release for adoption, the group choosing release for adoption thought they didn't have the ability to rear their babies and they took a negative attitude toward pregnancy compared with the group choosing to keep their babies. The group opting for release for adoption supposed that child rearing will interfere with their education, and they have a negative attitude about child rearing in general.

This study used the person-oriented approach to explore differences in narrative representations of 97 4-, 5- and 6-year old children (30 foster care, 40 biological family, 17 adopted). Using the MacArthur Story Stem Battery (Bretherton et al., 1990), observations were made to obtain children's narrative representations of content themes and performances. Descriptive statistics, ANOV A and hierarchical cluster analyses were performed. The results of this study were that : (1) Biological family children showed more empathy/helping representations. Foster care children and adopted children showed more anxious representations, and foster care children showed more dysregulated aggression. (2) Four clusters of foster care and adopted children and five clusters of family biological children were found.

In case of tissue characterization from ultrasonic echo signal, it is difficult to evaluate an absolute physical quantity because of redundancy in the echo signal. For it, in this paper a possibility of characterization of ultrasonic velocity distribution in multilayered medium using dip points analysis method from the reflected echo spectrum is discussed. To prove the possibility of this method, effect of interference phenomenon, impedance difference, attenuation, and thickness is discussed by computer simulation, and then the results confirm the effectiveness. And results of simple experiment are presented.

This study was undertaken to investigate to know whether spleen and lymph node cells from immunized mice can transfer systemically the delayed-type hypersensitivity(DTH) reaction to Salmonella typhimurium and to characterize the lymphoid cells using glass, nylon wool and rabbit anti-mouse thymocyte serum. Mice, C57BL/6 or ICR, were immunized subcutaneously at 11, 8 and 2 days before adoptive systemic transfer with $100{\mu}g$ of protein antigen from S. typhimurium in complete Freund adjuvant. It was found that DTH reaction to S. typhimurium could be transferred to normal recipient systemically by both spleen and lymph node cells($10^8\;cells$, respectively) from immunized mice. The cells responsible for this transfer of DTH reaction were glass nonadherent T lymphocytes.

The essay examines two contemporary American plays that portray adult Korean American adoptees' return to South Korea: How to Be a Korean Woman (2012) by Sunmee Chomet and Middle Brother (2014) by Eric Sharp. While the existing scholarship on transnational adoption has discussed homecoming as a predominantly female experience of birth mothers and daughters, Chomet and Sharp suggest the differing ways in which the adoptee subjectivity is re-imagined in particularly gendered ways after homecoming. In these plays, adult adoptees' repeated, mundane bodily performances of Korean cultural norms illustrate how notions of femininity and masculinity are inscribed onto the body of adoptee individuals under the patriarchal system. Such performative construction of Korean-ness departs from the earlier theatrical representations of young, adolescent adoptees' homecoming that served as a symbolic rite of passage, a necessary process through which they would gain cultural hybridity and mature into cosmopolitan American-ness.

Purpose : We analyzed clinical features and causal viruses of acute lower respiratory tract infections(LRTIs) in order to improve the management of these infections. Methods : From end of April to early May 2001, amongst 30 children at a local institute for children's adoption and welfare, 13 were admitted to the hospital with the diagnostic impression of acute LRTIs. Nasopharyngeal aspirates were sent in Seoul National University Hospital for viral culture of respiratory syncytial virus(RSV), adenovirus, parainfluenza virus. Results : One or more viral agents were identified in 4 cases(30.7%) : were RSV(15.4%), adenovirus(7.7%), and a mix of these two viruses(7.7%). Initial symptoms were fever(69%), cough(100%), tachypnea(54%), chest retraction(69%), rale(85%) and wheezing(15%). Leukocytosis was noted in 23%, CRP increased more than 10 mg/L in 46%. Chest X-ray abnormalities were 69%. Conclusion : Although viruses were identified in 30.7%, further studies should be made for prevention and treatment of acute viral LRTIs.

In Korea, overseas adoption has been practiced for more than 50 years. Initially, overseas adoption began with the objective to provide permanent homes for Korean war orphans, including mixed-blood children. From 1953 to 2007, about 160,000 Korean children were placed worldwide through overseas adoption and approximately 70,000 children were adopted in Korea. During that period, Korea developed into one of leading industrial countries in the world and the family norms changed dramatically. Since 1989, the Korean government has made diverse efforts to increase domestic adoptions and to support adopted families through the revisions to Korea's Child Welfare Law. However, it is not enough to reduce overseas adoptions rapidly because the Korean government's economic support for adopted families is not adequate and Korean sentiments regarding adoption have not changed. Being an international adoptee is a unique experience, involving dissimilarities of race, ethnicity, and culture. Clearly, it is very important for us to focus on placing Korean children in the best possible environment. Therefore, Korea must make diverse efforts to reduce overseas adoptions and to encourage domestic adoption. First, Korean society has to try to reduce the number of children who need out-of-home care. Second, the Korean government and people should make an effort to increase domestic adoptions, including adoptions of disabled and older children. Finally, the Korean government and adoption agencies have to provide professional pre-adoption and post-adoption services for international adoptees and adoptive parents.

In this study, unwed mothers residing in nine residental facilities were surveyed by questionnaires. Those facilities were selected from national welfare facilities officially registered for single-parent families in 2011. The selected facilities were two places in Seoul, six places in Gyeonggi Province and one place in Chungcheong Province. The surveyed data were analyzed by statistical methods such as frequency, percentage, one way ANOVA, chi-square test and t-test, binary logistic regression using SPSS ver.17.0 program. As a result, their decision of adoption or self-nurture on their child was significantly affected by various factors. Among pregnancy-related factors, pregnancy recognition time was significantly different between two groups. Among personal factors, their age and cognition of parental role were important factors to differentiate two groups. In the analysis related with social resources, the self-nurture group had significantly higher experience and satisfaction on welfare service and lodging & boarding service compared to those of the adoption-choice group.

본 논문은 국가별 추계인구와 미래 9개년 인구관련 설명변수들의 추정값을 통하여 적정인구 모형을 구형하고 한국의 적정인구를 추정하는데 목적이 있다. 후생을 고려한 생산함수 확장모형, 세계 176개국의 표본자료 그리고 다중회귀분석을 이용하여 $2000{\sim}2300$년 한국의 적정인구를 추정하고 그 추세곡선을 나타내는 것이다. 모형의 종속변수는 UN에 의한 세계각국의 추계인구이고, 설명변수는 9개 변수 즉 PPP GDP, 인접지역 경제통합율, 교육수준, 영어구사비율, 국토유효면적, 에너지량, 기온, 수자원량, 무역거리이다. 연구결과는 다음과 같다. $2000{\sim}2300$년 한국의 적정인구는 $4,350{\sim}4,950$만명으로 추정되며, 2000년${\sim}$2050년은 $4,700{\sim}5,010$만명, 2050년${\sim}2100$년은 $4,770{\sim}4,400$만명이 된다. 2125년 최저점 4,350만명을 통과한 후 점진적으로 2300년의 4,870만명으로 접근해 갈 것으로 추정된다. 연구결과의 시사점은 네 가지이다. 첫째 한국의 적정인구가 2125년을 기준으로 이전은 감소 이후는 증가 추세일 것이므로 정책결정시 적정한 목표인구를 설정해야 한다는 점이다. 둘째 현 추세로 진행되면 2050년 이후 적정인구가 추계인구보다 $500{\sim}600$만명 더 많아진다는 점이다. 셋째 2125년 이전의 적정인구는 좁게 $4,770{\sim}4,545$만명으로서, 출산율 향상을 통한 적정인구의 유지 노력이 필요하다는 점이다. 넷째 적정인구 추세의 기복은 출산기피로 인한 인구감소 때문으로 출산지원과 입양 및 이민 유입의 정책에 따라 변화될 수 있다는 점이다.
