국내 타운하우스 실내에 표현된 인테리어 디자인 스타일 및 Coordination 특성에 관한 연구
백진영(Baek, Jin-Young),최상헌(Choi, Sang-Hun) 한국실내디자인학회 2009 한국실내디자인학회 학술대회논문집 Vol.11 No.1
Recently, slight change has been detected in the type of house around the housing developmentsite in suburban areas. People have tried to avoid the standardized apartment and put more emphasis on healthy life. Therefore, townhouses which have the advantages of both apartments and single-family homes have drawn great attention. Many people expect that townhouses would solve the problems of apartments and improve the quality of life. As premium houses, townhouses have paid great attention to interior space and structure, using luxurious and stylish finishing materials. This study has attempted to investigate the coordination elements and the trend by style through literature review on interior design coordination of townhouses and find out the trend of coordination style in domestic townhouses through case studies.

본 논문은 열 해석 시뮬레이션과 주조로의 구조 변경을 통한 실리콘 잉곳의 방향성 응고에 대한 연구이다. 열 해석 시뮬레이션에 의한 결과, 용융은 유지 시간이 80분일 때 실리콘이 전체적으로 고르게 용융 온도에 도달하였 고 냉각은 상부 냉각 온도가 1,400℃와 60분 냉각 시 가장 좋은 결과 값을 나타내었다. 제작된 웨이퍼가 기존의 상용 웨이퍼보다 결정립계에서의 에칭이 훨씬 적게 이루어졌다. FTIR 측정결과 산소와 탄소 모두 모두 임계값 이하의 불 순물로 존재함을 확인하였다. NAA 분석 결과 총 18가지 금속 불순물이 검출 되었지만, 농도 분포는 같은 위치에서 위와 아래의 차이는 크게 나지 않고, 어떤 특정한 위치에서 한쪽으로 집중되거나 어떤 경향성 없이 전체의 샘플의 모 든 부분에서 농도가 거의 일정하게 분포를 나타냈다. This paper is the study for the directional solidification of the ingot through the thermal analysis simulation and structural change of casting furnace. With the results of thermal analysis simulation, the silicon as a whole has reached the melting temperature as the retention time 80 min. The best cooling conditions showed at the upper cooling temperature 1,400℃ and cooling time 60min. The fabricated wafers showed the superior etching result at the grain boundary than that of existing commercial wafers. The FTIR measurements of oxygen and carbon impurities were not in the critical value for solar conversion efficiency. The NAA analysis of metal impurities were also detected the total number of 18 different metals, but the concentration distribution showed no significant positional deviations in the same position from the top to the bottom.

Objective : To report the prevalence of lupus anticoagulants and anticardiolipin antibodies in patients with recurrent spontaneous abortion and infertility. Material and Method: Lupus anticoagulants and anticardiolipin antibodies were analyzed by Diluted Russell's Viper Venom Test (DRVVT) and solid phase enzyme immunoassay, respectively. Results : In 200 patients with infertility, there were 6 cases (3%) with positive lupus anticoagulants or anticardiolipin antibodies. Of these, 3 patients (1.5%) showed positive lupus anticoagulants and anticardiolipin antibodies, respectively. In 120 patients with recurrent spontaneous abortion, there were 13 cases (10.8%) of positive lupus anticoagulants or anticardiolipin antibodies. Of these, one patient (1%) showed lupus anticoagulants and 12 patients (10%) showed anticardiolipin antibodies. But in two groups, there was no cases with positive lupus anticoagulants and anticardiolipin antibodies. Conclusion: Lupus anticoagulants and anticardiolipin antibodies are definite cause of recurrent spontaneous abortion. There has been a speculation that they might be associated with infertility and repeated IVF failures. But it was found that the role of lupus anticoagulants and anticardiolipin antibodies in these cases are not clear.

검사의 질 향상과 국제표준화의 상용화 정도관리물질을 이용한 Westgard multi-rules 적용의 유용성은 이미 알려져 있다. 그러나 핵의학 체외검사의 특성상 정도관리물질과 환자검체의 동시 계측으로 인한 측정횟수의 증가에 따라 Westgard multi-rules법을 적용함에 있어 어려움이 있다. 이에 본 연구는 핵의학 체외검사에서 상용화 정도관리물질을 이용한 Westgard multi-rules 적용의 유용성과 보완, 개선을 통해 내부정도관리의 효율성 향상을 조사하였다. 2013년 01월부터 2016년 06월까지 삼성서울병원 핵의학과 체외검사실 통합의료시스템에 기록된 총 282건의 적용된 계통오차 multi-rules (22s, 101s)과 117건의 조치사항 기록을 분석하였다. 조치사항은 multi-rules 중 계통오차의 규칙이 적용 되었을 때 기록하는 원인분석으로 정도관리물질 오류, 실험과정 오류, 검사키트 로트번호 관리 오류, 기타 등 총 4개의 대분류로 구성하였다. Westgard multi-rules 적용을 통해 조치사항을 분석한 결과 정도관리물질 오류가 62건, 실험과정 오류가 24건, 검사키트 로트번호 관리오류가 18건, 기타 13건으로 분류되었다. 정도관리물질 오류를 방지하고자 개선사항으로 기존에 각 검사자마다 사용하던 방식을 담당자 지정 방식으로 변경하여 모든 검사의 하루 소비량을 분주하여 공동사용을 하였고, 나머지 오류를 방지하고자 검사 전후 모든 과정을 표준화 하여 검사실내 어느 검사자가 시행 하더라도 일원화할 수 있게 하였다. 정도관리물질 오류를 개선한 결과 해동 후 2일 이내 신선한 물질을 사용 가능하였고 같은 물질을 사용하는 검사끼리 비교가 가능해져 물질에 의한 오류인지 명확해짐으로 계통오차 발생원인이 정도관리물질 오류로 기록하는 건수가 줄어들었다. 또한 정도관리물질의 로트번호 변경 시 교체시기가 같아 관리가 용이해졌고, 물질 사용량의 감소로 경제적 효과를 얻을 수 있었다. 그리고 검사표준화 적용 후, 계통오차의 규칙인 22s와 101s의 발생건수가 개선 전 보다 월 평균 2건 이상 줄어드는 결과를 보였다. Multi-rules의 적용을 통한 계통오차의 빠른 확인을 위해 정도관리물질의 체계적인 관리와 목표값과 표준편자의 설정 및 관리가 바탕이 되어야하며, 계통오차 발생 시 검사의 원인분석을 통한 조치사항을 기록하는 것이 중요함을 확인하였다. 본 실험의 결과로 Westgard multi-rules 적용 분석을 통해 발생 오류의 기재와 원인을 효율적으로 분석함으로써 핵의학 검사 내부정도관리의 질적 향상과 정확하고 신속한 결과보고에 기여할 것으로 사료된다. Purpose Westgard multi-rules application based on test quality improvement and commercialized international standard has been widely used in quality control. However, it is difficult to applicate the Westgard multi-rules in nuclear medicine in vitro tests due to the larger sample sizes and the simultaneous measurement of quality control material and patient sample. This study investigated the usefulness of Westgard multi-rules application in nuclear medicine in vitro tests. Materials and Methods A total of 282 systematic error multi-rules (22s, 101s) recorded in the samsung medical center computer system from January 2013 to June 2016 along with 117 cases of corrective measure record was analyzed. The Quality control implementation is recorded in Hospital information system were divided into 4 high-level areas including quality control material error, experimental procedural error, Kit lot number management error, and others. To prevent quality control material error, the existing method that each staff used their own method was changed. The staff who in charge of managing the quality control material was designated and daily consumption amount of every test was strictly controlled by one person. To prevent other errors, every test step was standardized so that the entire test procedures are identically implemented. Results The total quality control implementation was 117 cases; As a result, 62 quality control material errors were 62 cases, experimental process errors were 24 cases, Kit lot number control errors were 18 cases, and other errors were 13 cases. The quality control material error was corrected and could be used fresh materials within 2 days after thawing. The cases of systemic error were decreased to causes as quality control material error. The quality control materials were reduced above 10 vials to a monthly average. In addition, these errors of experimental processing and Kit lot number were improved by test standardization. Consequently, the cases of 101s and 22s in systematic error rules decreased at least 2 cases to a monthly average. Conclusion To confirm of systematic error through multi-rules application quickly, it is necessary to base on management of the QC material, target values and standard deviation. Moreover, in the event of a systematic error, it was found important to record measures based on test cause analysis. The experiment results are expected to contribute to internal quality control improvement and prompt and accurate result reporting through error recording and causal analysis based on Westgard multi-rules analysis.

Human senses have been studied widely. Many studied are being actively conducted to analyze correlations between two or more different senses. Among them, research on tactile visuality where a subject can indirectly experience visual sensation through tactile elements is also progressing in various fields. In this study, we analyzed color information by having subjects perceive sandpapers with different roughness through tactile sense, then having them choose a color that is reminiscent of the tactile sensation. Unlike existing tactile-visuality studies allowing the perception of indirect visual sense by using tactile sense, this study shows that it is possible to analyze with quantitative value by representing visual image perceived by tactile sense as a color. This study will contribute to emotional evaluation research that combines two or more of the senses felt by humans, and especially is considered to be useful as basic data when conducting research about tactile visuality or auditory tactile sense.
