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.

Objective : Internal carotid-posterior communicating artery(IC-PC) aneurysms can be clipped easily without any special preparations. Occasionally, however, it is difficult to clip the low-lying IC-PC aneurysms without some kinds of additional procedures. Clinical Material and Methods : We experienced four cases of low-lying IC-PC aneurysms, which the intradural anterior clinoidectomy and/or anterior petroclinoid fold(APF) resection was essential to expose the proximal side of the aneurysmal neck and/or proximal control. One patient harbored two low-lying IC-PC aneurysms bilaterally. The patients were divided into two groups according to the necessity of anterior clinoidectomy : Group I(n=4) that needed an intradural clinoidectomy and/or APF resection and Group II(n=29) that had IC-PC aneurysms, easily clipped without any special preparation. Also, various radiometric parameters were measured through the preoperative angiograms. Results : The incidence of such aneurysms was 12% among a total of thirty-three surgically treated IC-PC aneurysms during lasr 3 years. Among four cases, three cases presented with subarachnoid hemorrhage and all aneurysmal sac projected to postero-inferior direction. In our study, We initially considered the necessity of intraoperative anterior clinoid process(ACP) removal and/or resection of APF in cases of shorter distance less than 5.6mm between the proximal aneurysmal sac and tip of the ACP(p<0.001), and the proximal portion of aneurysmal neck has located below the interclinoid line(p=0.001). Conclusion : Through a careful preoperative evaluation, some radiometric parameters can be used to determine whether the ACP should be removed in clipping of the low-lying IC-PC aneurysms. Unlike to total removal of the ACP, the intradural partial anterior clinolidectomy and/or APF resection, which are more familiar to surgeons, reduce the risks of the premature rupture, operative time, and also contribute a more precise clip placement with proximal control than the extradural clinoidectomy.

Multi-wires와 half-cell을 사용한 모듈은 다수의 얇은 원형 와이어를 리본으로 사용하고 셀 면적을 절반으로 줄여 출력을 높인 결정질 실리콘 태양전지 모듈 기술이다. 이러한 특징으로 인해 multi-wires 기반 half-cell 모듈은 접합 공정 후 접합 특성과 효율 측면에서 기존 모듈 기술과 차이를 보이는 것으로 보고되고 있다. 본 연구에서는 multi-wires 기반의 half-cell 접합 공정 후 초기 접합 특성과 효율에 영향을 끼치는 인자를 찾고자 하였다. 와이어 두께와 솔더 두께 및 플럭스 종류를 조절해 효율과 접착력을 측정하고 접합부 단면을 FE-SEM과 EDX 분석했다. 와이어와 솔더 두께에 따른 접착력과 효율 차이는 적었지만, 플럭스 종류에 따른 차이가 관찰되었다. FE-SEM과 EDX 분석에서 플럭스의 고형분 함량과 솔더 두께에 따라 솔더 조인트와 금속화합물 층 형성의 달라짐이 보였고, 이로 인해 접합 특성과 효율이 영향을 받은 것으로 보인다.

A default server strategy is a very popular scheme for managing location and state information of mobile hosts in cellular networks. But the communication cost increases if the call requests are frequent and the distant between the default server and the client is long. Still more, any connection to a mobile host cannot be established when the default server of the destination mobile host fails. These problems can be solved by replicating default server and by letting nearest replicated default server process the query request which is sent from a client . It is important to allocate replicated default servers efficiently in networks and determine the number of replicated default servers. In this paper, we suggest and evaluate a default server replication strategy to reduce communication costs and to improve service availabilities. Furthermore we propose and evaluate an optimized allocation algorithm and an optimal replication degree for replicating default servers in nn grid networks and binary tree networks. 셀룰라 기반의 이동컴퓨팅 환경에서 이동 호스트의 위치 및 상태관리를 위하여 디폴트 서버(default sever)기법이 널리 사용되나 이동 호스트로의 호 요청이 많은 경우나 호를 요청한 클라이언트가 디폴트서버와 멀리 떨어진 경우 통신 오버헤드가 커지며, 디폴트서버에 결함이 발생할 경우 해당 이동 호스트에 대한 연결이 불가능해 진다. 디폴트 서버를 여러 개로 중복 시키면 위와 같은 문제점을 경감시키고 디폴트 서버와의 통신비용을 줄일 수 있다. 그러나 디폴트 서버를 중복 시킬 경우 전체 통신비용은 이동 호스트의 이동 성향과 질의(query) 요청의 빈도, 중복 디폴트 서버의 할당 위치와 중복 개수에 영향을 받는다. 본 논문에서는 디폴트 서버를 통신 환경에 따라 최적의 위치에 할당 시켰을 때 nn grid네트워크 환경과 이진트리 네트워크 환경에서 각각의 최적 디폴트 서버 중복 개수를 구하는 방법을 제시하였고, 시뮬레이션을 통하여 수학적 방법이 유용함을 보였다.

Background The costal cartilage allows for versatile and stable cartilage supply for rhi-noplasty but disadvantages remain; to minimize these, the 10th costal cartilage was used. We present our experience with the use of the 10th costal cartilage as autologous graft material for rhinoplasty. Methods Sixty-four patients whose 10th costal cartilage had been used for correction of severe caudal nasal deviation, secondary cleft lip nasal deformity, and secondary rhi-noplasty with difficulty using the septal and auricular cartilages were enrolled in this study from November 2008 to December 2012. To evaluate the efficacy and safety of this method in rhinoplasty, donor-site morbidity, scarring, and postoperative results, including availability of graft material and complications, were assessed. Results The mean time for cartilage harvesting was 18 minutes, and the mean length of the harvested cartilage was 2.4 cm. The harvested cartilage was used for columellar struts and tip onlay grafts. The natural curvature of the 10th costal cartilage was used, depending on the purpose of the strut. It could be applied without carving in 38 cases (59%). Although revision was performed in three patients, there were no graft-related complications. Conclusions The 10th costal cartilage can be harvested safely and quickly, and its han-dling procedure is simple. As such, it is a good option as an autologous graft for rhino-plasty.

An easy and efficient method is proposed for a computation of reliability of preprocessing filters in the fire control system when the sensor data are frequently unreliable depending on the operation environment. It computes state transition probability matrix after modeling filter states as a Markov process, and computing false alarm and detection probability of each filter state under the given sensor failure probability. It shows that two important indices such as distributed state probability and error variance can be derived easily for a reliability assessment of the given sensor fusion system.

When paper which was applied as insulation in oil-filled transformer was aged by thermal, its electrical, mechanical and chemical characteristics were changed and deteriorated. Therefore operating temperature was more higher, damage of paper was more quicker. Insulating paper which was generally made with cellulose was degraded, polymer of long length chain was decomposed as a monomer and CO, $CO_2$ gas and/or by-product such as furfural was produced from paper at the same time. In according with detection these gas and furfural by dissolved gas analysis(DGA) and high performance liquid chromatography(HPLC), we have investigated effects of CO, $CO_2$ gas and furfural on insulation of paper. Also we have analyzed for correlation between furfural and CO, $CO_2$ gas using linear regression method that was known as useful, credible statistical analysis.
