This study was conducted to examine the experiences of family relationships that multicultural young adult experience in families and examines how multicultural young adult family relationship affect in transition. In order to explore the experiences of multicultural young adults, 12 young adults who were born in Korea or immigrated were recruited as research participants. A consensus qualitative research method was used to explore multicultural young adults’s family adaptation and communication experiences. The interview was conducted in a semi-structured format for an average of about 60 to 70 minutes. In order to secure the validity of the research results, two experts received opinions on the appropriateness of the broad fields and categories derived from the research. Finally, 5 domains and 18 categories were derived: ‘Various experiences with family members in the growth process of youth born in Korea.' ‘Formation of a new family and experiences within the mid-immigrant youth.', ‘Cultural adaptation and family relationship experience of foreign parents.’, ‘Effect of the family on identity formation and growth of youth with migration background in the transition period.’ ‘Acceptance of bi-culture due to positive experiences in parent and family.’Based on the results of this study, the experiences of youth with migratory backgrounds in their young adults families were described, and the implications of the role of family relationships in identity formation were described. It was suggested that a study on multicultural young adults is necessary. 본 연구는 다문화 가정 청년들이 청년기 가족 안에서 경험하는 가족관계 경험을 탐색하여 다문화 가정 청년들의 가족 관계가 성인 전환기에 있는 청년들에게 어떤 영향을 미치는지 확인하기 위한 목적으로 진행되었다. 다문화 가정 청년들의 경험을 탐색하기 위해 국내출생과 중도입국 다문화 가정 청년 12명을 연구 참가자로 모집하였다. 분석을 위해서 합의적 질적 연구(CQR) 방법을 사용하였으며, 반 구조화된 형식으로 평균적으로 약 60~70분의 인터뷰를 진행하였다. 연구결과 ‘국내출생 청년들의 성장과정에서 가족 구성원과 다양한 경험’, ‘중도입국 청년들의 새로운 가족형성과 그 안에서의경험’, ‘외국인 부모의 문화적응과 가족관계 경험’, ‘다문화 가정 청년들의 이중문화 수용에 가족이 미친 영향’, ‘다문화 가정 청년들의 정체성 형성과 성장에 가족이 미친 영향’의 5개 영역과 18개 범주가 도출되었다. 본 연구의 결과를 바탕으로 다문화 가정 청년들의 청년기 가족 안에서의 경험을 살펴보고 정체성 형성에 가족관계의 역할에 대한시사점을 논하였다.

IEEE 802.16e 시스템은 OFDMA/TDD 방식의 라디오 프레임을 기반으로 실시간 서비스와 비실시간 서비스를 동시에 지원한다. 따라서 시스템의 전체 성능을 최대화 하면서도 실시간 서비스 사용자에게 적절한 정도의 우선권을 부여하여 실시간 서비스 사용자의 지연을 미리 정한 한도 이내로 제한하여야 한다. 본 논문에서는 실시간 서비스 사용자의 채널 상태와 지연 시간, 트래픽 부하에 따라 실시간 서비스 사용자의 지연 임계값을 적응적으로 결정하여 실시간 서비스 사용자의 지연 한도를 보장하면서도 시스템 성능을 극대화하는 자원할당 모듈의 설계 및 구현안을 제시한다. 본 논문에서 제시한 자원할당 시스템의 설계는 IEEE 802.16e 시스템에 장착돼 테스트를 수행하며 이를 통해 OFDMA/TDD 에서의 실시간 및 비실시간 서비스의 적응적 임계값 기반 공통 자원할당 기법의 유용성을 증명한다.

Nowadays, diseases related with breast are increasing rapidly and because of this high quality of resolution images is required to get clear detail specially for early detection and diagnosis. It has a tendency to use digital equipments than analog one in clinic. In this experiment, DR, CR, and Film are used for the resolution applied by AEC. Resolution phantom in DR was 7 LP·mm-1 in both verticality and horizontality. In CR, however, it was 6 LP·mm-1 in both which was lower this standard. The resolution stayed in range of standard in Film but it showed differences between 11~14 LP·mm-1 Overall, the difference of resolution was displayed Film, DR and CR, in order, which means the study is needed for more high quality of digital images.

The purpose of our study was to evaluate the characteristics and the changes of low vision patients over ten years in Korea, and to establish useful data for planning low vision services, active care and rehabilitation. We conducted a retrospective study of 681 low vision patients who visited two low vision clinics in Seoul from 1995 to 2008. Age and sex distribution, cause of low vision, type of prescribed low vision aids, and changes of the characteristics were reviewed. In result, male were more than female. The age group between 11 and 20-yr-old (18.1%) was the largest age group. Optic atrophy (28.3%) was main causes of low vision. However, elderly low vision patients is increasing and macular degeneration is becoming a leading cause of low vision (P<0.05). One thousand five low vision aids (LVAs) were prescribed for 681 patients (1.46±0.62 aids for each patient). Near LVAs were prescribed more than distance LVAs. In most patients, the use of LVAs improved both near and distance visual function. This study is the first survey of a large number of low vision patients over a ten year period in Korea. On the base of this study, the planning of low vision services and more active rehabilitation for low vision patients, especially elderly patients, need in Korea.

Thermal shock is a physical phenomenon that occurs during the exposure to rapidly high temperature and pressure changes or during quenching of a material. The rocket nozzle throat is exposed to combustion gas of high temperature. Therefore, it is important to select suitable materials having the appropriate thermal shock resistance and to evaluate these materials for rocket nozzle design. The material of this study is ATJ graphite, which is the candidate material for rocket nozzle throat. This study presents an experimental method to evaluate the thermal shock resistance and thermal shock fracture toughness of ATJ graphite using laser irradiation. In particular, thermal shock resistance tests are conducted with changes of specimen thickness, with laser source irradiated at the center of the specimen. Temperature distributions on the specimen surface are detected using type K and C thermocouples. SEM (scanning electron microscope) is used to observe the thermal cracks on specimen surface.

Anion exchange groups were introduced into porous hollow fiber membranes by radiation-induced ploymerization. The epoxy group produced in the GMA-grafted hollow fiber membrane was converted into anion-exchange groups by reaction with Diethylamine(DEA). Triethylamine(TEA). Ethanolamine(EtA). Diethanolamine(DEtA). The D-, L-Tryptophan solution was forced to permeate across the hollow fiber DEA, TEA, EtA, DEtA memberan. When measurements of anion-exchange capacity of the DEA, TEA, EtA, DEtA memberan, the DEA membrane having higher adsorption capacity than TEA, EtA, DEtA membrane.

Both immunoelectron microscopy(IEM) and immunogold conjugate immunoelectron microscopy (IGC-IEM) techniques were developed for the detection of porcine epidemic diarrhea virus(PEDV) from the feces. Fecal samples were incubated sequentially with anti-PEDV monoclonal antibody(MoAb) and immunogold conjugated goat anti-mouse IgG+IgM. Then negatively stained, mounted on the formvar carbon-coated copper EM grids and observed by the transmission electron microscope. By the direct electron microscopy(DEM), coronavirus particles were observed from 17 cases of total 33 fecal samples of grower pigs and sows. The virons of coronavirus were moderately pleomorphic but mostly spherical, with a diameter ranged from 90 to 190nm. PED virus particles were identified from 15 cases of 17 DEM positive samples by the IEM and IGC-IEM techniques. Aggregates of PED virus coated with specific antibody were seen in fecal samples incubated with homologous anti-PED virus MoAb but not in control samples incubated with anti-TGE virus MoAb. Following incubation with immunogold-conjugated secondary antibody, the gold granules were usually distributed around and among the virus particles and soluble and viral particle-associated antigen. So, IEM and IGC-IEM techniques were proved a rapid and sensitive methods for detection and identification of PED virus from fecal and intestinal contents.

Neospora caninum에 의한 젖소의 반복유산

김재훈,황의경,손현주,진영화,윤순식,김대용,Kim, Jae-hoon,Hwang, Eui-kyung,Sohn, Hyun-joo,Jean, Young-hwa,Yoon, Soon-seek,Kim, Dae-yong 대한수의학회 1998 大韓獸醫學會誌 Vol.38 No.4

A case of repeated bovine abortion caused by Neospora caninum is described. The 3-year-old Holstein cow, which was seropositive to N caninum antibody by indirect immunofluoresent assay, aborted consecutively within a 10-month period. Two fetuses of 6- or 5-month of gestation were aborted in June 1996 and March 1997, respectively. Histologically, multifocal necrotizing encephalitis, nonsuppurative periportal hepatitis, myocarditis, and myositis were observed in both fetuses. Tachyzoites or tissue cysts detected in the brain, heart and liver were positive to N caninum but negative to Toxoplasma gondii by immunohistochemical method. The results of our study demonstrate that repeated abortion due to N caninum actually occurs in Korea. This is believed to the first report of repeated abortion associated with N caninum in Korea.
