Objective : The purpose of this study is to present the desirable model for the promotion of care coordination between Korean Medicine and Western Medicine and develope the instrument to measure the level of coordination. Moreover, we verified the validity and reliability of the developed Instrument. Method : In this study, We developed the 16 items regarding care coordination in Korean Medicine and Western Medicine by literature review and expert interviews. In addition, we verified the validity and reliability of the instrument as a methodological research. Results : We developed two factors such as 'Inter-professional activities' and 'Organizational support' as the instrument to measure the level of care coordination, and each of seven, eight total of 15 measurement items are listed. Conclusion : Since the legal permission, the level and type of care coordination and the effects of them are needed to be checked. So, the measurement instrument driven by this study has a political signification in healthcare system specially in these times. In addition, by utilizing this instrument, we propose to perform a variety of future studies on the levels of healthcare coordination and related outcomes.

[ $TiO_{2}-solution$ ] was aaded in $SiO_{2}-solution$ by various composition. $SiO_{2}-TiO_{2}$ thin films were obtained by the dip-coating method on the $SiO_{2}$ glass substrates, and then heat-treated at various temperature. Nano-size $TiO_{2}$ particles dispersed $SiO_{2}-TiO_{2}$ films showed absorption peak by quantum size effect at short wavelength region $350{\sim}400nm$, which made them good candidates for non-linear optical materials and photo-catalytic materials. The thickness of $SiO_{2}-TiO_{2}$ films were $300{\sim}430nm$. The contact angle of $SiO_{2}-TiO_{2}$ films for water was $5.3{\sim}47.9^{\circ}$, and therefore it is clear that $SiO_{2}-TiO_{2}$ films have super hydrophilic properties and the self-cleaning effects.

제2형 콜라겐 경구관용 유도 동물모델에서 수지상 세포의 Indoleamine 2,3-dioxygenase 의존성 관절염 항원 특이 T세포 증식반응 제어 연구

박민정,민소연,박경수,조미라,조영규,민준기,윤종현,박성환,김호연 대한면역학회 2005 Immune Network Vol.5 No.4

Background: Immune regulatory dendritic cells (DCs) play an important role in maintaining self-tolerance. Recent evidences demonstrate that DCs expressing indoleamine 2,3-dioxygenase (IDO), which is involved in tryptophan catabolism, play an important role in immunoregulation and tolerance and induce T cell apoptosis. This study was devised to examine the role of IDO in the oral tolerance induction in collagen-induced arthritis (CIA) mouse model. Methods: Beginning 2 weeks before immunization, CII was fed six times to DBA/1 mice and the effect on arthritis was assessed. In tolerized mice, CD11c DCs were isolated and stimulated with CII, IFN-γ, and LPS with or without IDO inhibitor, 1-methyl-DL-tryptophan (1-MT) and IDO expression by CD11c DCs was analyzed using FACS and RT-PCR. The expression of IDO, MHC II, CD80, and CD86 by CD11c DCs were examined using confocal microscopy. Regulatory effect of CD11c DCs on Ag-specific T cell proliferative response to CII was examined by mixed lymphocyte reaction (MLR) with or without 1-MT. Results: The proportion of IDO-expressing CD11c DCs was slightly higher in tolerized mice than in CIA mice and significantly increased after stimulation with CII, IFN-γ, and LPS in an IDO- dependent manner. On confocal microscopic examination, the expression of IDO was higher and those of MHC II and CD86 were lower in CD11c DCs from tolerized mice compared to those from CIA mice. On MLR, CD11c DCs from tolerized mice inhibited T cell proliferative response to CII in an IDO-dependent manner. Conclusion: Enhanced IDO expression by CD11c DCs from tolerized mice may contribute to the regulation of proliferative response of CII-reactive T cells and could be involved in the induction of oral tolerance to CII.

We introduce the empirical model decomposition (EMD) to decompose a time series into a set of components in the time-frequency domain. By using EMD, we also extract cycle and trend components from major Korean macroeconomic indices and forecast the indices with the components combined. In order to evaluate their efficiencies, we investigate volatility, autocorrelation, persistence, Granger causality, nonstationarity, and forecasting performance. They are then compared with those by Hodrick-Prescott filter which is the most commonly used method.

AI 편향(AI Bias) 심화 요인 탄색 기반 완화 방안에 대한 연구

박민정,손영진,채상미 한국경영정보학회 2024 한국경영정보학회 학술대회논문집 Vol.2024 No.05

AI 모델의 편향성은 해당 모델의 예측, 추론 등의 결과가 특정 집단에 대하여 불리하게 작용하거나 특정 상황에 대하여 왜곡된 예측을 하는 현상을 의미한다. 이러한 AI의 편향성은 부정확한 예측에 따른 모델 성능의 저하와 더불어 모델이 일부 집단에 대하여 불공정한 차별적인 결과를 발생시킴에 따라, 최근 들어 AI 윤리와 공정성의 관점에서 AI 모델의 편향성 완화 방안 마련을 위한 연구의 필요성이 제기되고 있다. AI 모델의 편향성을 형성하는 주요 요인에는 학습 데이터 불균형, 알고리즘 편향, 사회, 문화적 환경을 고려하지 못한 사용자 오류 등이 존재한다. 즉, 학습 데이터의 대표성 부족, 라벨링 오류 등의 데이터 편향성 및 학습 데이터에 적합하지 못한 알고리즘 적용에 따라 형성되는 알고리즘의 편향 등이 대표적이다. 이에 본 연구는 AI 모델에 내재된 편향성을 완화할 수 있는 방안을 data preprocessing, data in-processing, data post-processing 의 관점에서 제시하고자 한다.

A survey of total aflatoxin levels was conducted on 158 samples (nuts, fermented foods and their processed products) collected in local markets in Gyeonggi-do and Domestic Internet Site. The total aflatoxins were quantified by the immunoaffinity column clean-up method followed by high performance liquid chromatography (HPLC)-fluorescence detector (FLD). Aflatoxins were found in 45(28.5%) samples including 34 nuts and nut products, 7 soybean pastes, 1 meju, 1 bean product and 2 corn snacks with a range of 0.02 ~ 3.96 μg/kg. These results show that the contamination level of aflatoxin in foods consumed in Korea is low compared with the standard in Korea Food Code(10 μg/kg as aflatoxin B₁). Aflatoxin B₁ content was increased in peanuts and corn snacks during storage but it was decreased in doenjang (soybean paste).

The purpose of this study is to analyze the performance of ABEEK accredited engineering program in D University. Based on engineering students’ perceptions, this study explores how well the students are aware of the accredited engineering program, what change has been made to the courses, to what extent they have been participating in class and interacting with teachers and other students, to what extent they have been actively participating in extra-curricular activities, and to what extent they have achieved program outcomes. The survey was conducted in Fall 2014. The results are as follows: First, the students are well aware of the accredited engineering program; however, they are rarely aware of program outcomes. Second, the students were more satisfied with the major and design courses compared to the MSC and general education courses. Third, the students were more actively participated in the major and design courses compared to the MSC and general education courses. Fourth, the students were passively engaged in extra-curricular activities. Finally, the program outcomes related to soft skills showed low-achievement.

The increasing demand from researchers and policy makers for microdata has also increased related privacy and security concerns. During the past two decades, a large volume of literature on statistical disclosure control (SDC) has been published in international journals. This review paper introduces relatively recent SDC approaches to the communities of Korean statisticians and statistical agencies. In addition to the traditional masking techniques (such as microaggregation and noise addition), we introduce an online analytic system, differential privacy, and synthetic data. For each approach, the application example (with pros and cons, as well as methodology) is highlighted, so that the paper can assist statical agencies that seek a practical SDC approach.
