This study was performed to analyze systematically and validate empirically the influence of korean medicine service quality on satisfaction factors and revisiting intention. The candidates were patients visiting the one korean medicine hospital in Gyeongnam. We took a direct survey collected during 15 days May 1 to 15, 2016. For the survey I distributed a total of 250 questionnaire and used the final 230 of them in verifying this research model except unreliable data. The collected data were used statistics program SPSS WIN 22.0 and the research model were examined by AMOS 18.0. The main research results are follows. First, the most influencing factors on consumer satisfaction were public image factors and then human factors. and then effectiveness factors. Second, the most influencing factors on reuse intention were public image factors and then physical factors. Third, human and effectiveness factors of service quality factors in korean medicine hospital did not effect on revisiting intention directly but, effected on revisiting intention through mediation role of the customer satisfaction. Forth, satisfaction on the significant effect on reuse intention. so satisfaction has proved to be a important factor for reuse intention. The results of this study are expected to contribute to management efficiency and developmental improvement on korean medicine hospital policy and management efficiency and be used as a basis for leading to national health promotion through the development of korean medicine service.

The development of LBS(location-based services) due to the widespread mobile environment highlights the importance of POI(point of interest) information. The accurate and up-to-date POI has to be ensured to reflect the information of rapidly changing places. For the efficient construction of POI, here we propose the novel construction system for t he place information. This system is based on crowd-sourcing in which a great number of users participate. In addition, we utilize the graph data model to build the new concept of the place information covering the wide areas extending from the specific point. Moreover, the implementation of the new system applying the graph data model and crowd-sourcing is realized in this paper. That is, this study suggests the whole new concept of the place information and shows the clustering and the renewal of the place information through crowd-sourcing.

Objectives : This study was performed to analyze the effective components of essential oil obtained from Yongdamsagantang, which has been efficacious against leukorrhea in gynecologic diseases. Methods : I obtained the essential oils of Yongdamsagan-tang by hydrodistillation extraction method and supercritical fluid extraction(SFE) method, and then I analyzed those by GC/MS(Gas Chromatography/Mass Spectrum). Results : 1. The optimum SFE(Supercritical Fluid Extraction) condition was obtained in the following experiment conditions: pressure 200atm, temperature $45^{\circ}C$, duration of extraction 25minutes. 2. With GC(Gas Chromatography) and GC/MS(Gas Chromato- graphy/Mass Spectrum) analysis, I identified 37 compounds in the Yongdamsagan-tang's essential oil obtained through the SFE method. The main compounds were as follows : 3-Methyl-but-2-enoic acid,2,2-dimethyl-8-oxo-3,4-dihydro-2H,8H -pyrano[3,2-g]chromen-3-yl ester(49.81%), (Z)-6-Pentadecen-1 -ol(3.19%), (-)-Spathulenol(2.40%). 3. I identified 4 compounds in the Yongdamsagan-tang's essential oil obtained through the hydrodistillation method. The main compounds were as follows : 3-Methyl-but-2-enoic acid, 2,2-dimethyl-8-oxo-3,4-dihydro-2H,8H-pyrano [3,2-g]chromen-3-yl ester(2.61%). 4. 3-Methy I-but-2-enoic acid, 2,2-dimethyl-8-oxo-3,4-dihydro-2H,8H-pyrano[3,2-g] chromen-3-yl ester, all were identified in both the SFE method and the hydrodistillation method, but the others were not identified in common. 5. I also conducted an additional test in order to examine the essential oil's antimicrobial action against bacteria. Both MIC(Minimum Inhibitory Concentrations) and MBC(Minimum Bactericidal Concentrations) were $0.125mg/m{\ell}$ against N. meningitidis, however MIC and MBC were $1.0mg/m{\ell}$ in antimicrobial action against 12 different genera of bacteria.

Objectives : The purpose of this study is to investigate the effects of Chowiseungcheng-tang extracts on the preadipocytes proliferation in 3T3-L1 cell line, lipolysis of adipocytes in rat's epididymal adipocytes and localized fat accumulation of porcine by extraction methods(alcohol and water). Methods : Diminish preadipocytes proliferation and promote lipolysis of adipocytes do primary role to reduce obesity. So, we used 3T3-L1 mouse embryo fibroblasts(preadipocytes) and rat epididymal adipocytes from Sprague-Dawley rats to investigate the effects of Chowiseungcheng-tang extracts on the preadipocytes proliferation, lipolysis of adipocytes. They were treated with 0.01, 0.1, $1.0mg/m{\ell}$ Chowiseungcheng-tang alcohol and water extracts. And for the purpose of investigating the effects of Chowiseungcheng-tang alcohol and water extracts on the localized fat accumulation, we injected 0.1, 1.0, $10.0mg/m{\ell}$ Chowiseungcheng-tang extracts to porcine fat tissues and observed histological changes of them. Results : Following results were obtained from the preadipocytes proliferation and lipolysis of adipocytes and histological investigation of fat tissues. 1. Chowiseungcheng-tang extracts suppressed preadipocytes proliferation on the high dosage(especially $1.0mg/m{\ell}$), and especially alcohol extracts had better effects. 2. The alcohol extracts of Chowiseungcheng-tang decreased the activity of glycerol-3-phosphate dehydrogenase (GPDH) on the concentrations of 0.1, $1.0mg/m{\ell}$. Alcohol extracts had better effects than water extracts. 3. Chowiseungcheng-tang extracts increased lipolysis of adipocytes on the concentrations of 0.1, $1.0mg/m{\ell}$, and especially on the concentration of $1.0mg/m{\ell}$ alcohol extract of Chowiseungcheng-tang had better effect. 4. The water extract of Chowiseungcheng-tang had significant activity to the destruction of porcine fat cell membranes only on the concentration of $10.0mg/m{\ell}$, but alcohol extracts of Chowiseungcheng-tang had it on all concentrations. Conclusions : The alcohol extracts of Chowiseungcheng-tang had much better effects on the preadipoeytes proliferaton, lipolysis of adipocytes and localized fat accumulation than water extracts.

In order to obtain high accuracy with an convolutional neural network(CNN), it is necessary to set the optimal hyperparameters. However, the exact value of the hyperparameter that can make high performance is not known, and the optimal hyperparameter value is different based on the type of the dataset, therefore, it is necessary to find it through various experiments. In addition, since the range of hyperparameter values is wide and the number of combinations is large, it is necessary to find the optimal values of the hyperparameters after the experimental design in order to save time and computational costs. In this paper, we suggest an algorithm that use the design of experiments and grid search algorithm to determine the optimal hyperparameters for a classification problem. This algorithm determines the optima values of the hyperparameters that yields high performance using the factorial design of experiments. It is shown that the amount of computational time can be efficiently reduced and the accuracy can be improved by performing a grid search after reducing the search range of each hyperparameter through the experimental design. Moreover, Based on the experimental results, it was shown that the learning rate is the only hyperparameter that has the greatest effect on the performance of the model.

Liver is an important target of the toxicity of drugs, xenobiotics and oxidative stress. Acetaminophen pverdose causes acute liver injury in both humans and animals. This study was performed to observe the effect of sachunwhan and its component groups on recovery of hepatoxicity in acetaminophen treated rats. The experimental group was divided into 4 groups: sachungwhan(SC), samultang group(SC-1: 當歸, 川芎), chungyul group(SC-2: 龍膽草, 大黃, 梔子), and haepyo group(SC-3:羌活, 防風). Under the same condition Normal group was fed basal diet and water; Control group was injected acetaminophen and fed basal diet for 2 weeks; Experimental groups were injected acetaminophen and fed each extracts for 2 weeks respectively. The results were obtained as follows: 1. In the study on antioxidative defense system in vivo, SC reduced the amount of lipid peroxide in both serum and liver and showed activity on antioxidative enzymes such as catalase, glutathion. Other groups had effect only on glutathion. 2. In the study on hepatotoxicity(GOT, GPT, ${\gamma}$-GTP, ALP, LDH, Bilirubin), SC had a significant effect on recovery of hepatoxicity in acetaminophen treated rats. Other groups had no effect except SC-1 having effect on ${\gamma}$-GTP. As results shown, only Sachungwhan(SC) has significant effects on recovery of hepatoxicity and antioxidative defense system in vivo. These results suggest that Sachungwhan(SC) made antioxidative defense system active and it seemed to be very important to its effect on recovery of hepatoxicity. In the other hand, Component groups had no effect on recoverv of hepatoxicity and antioxidative defense system in vivo. This was thought that component drugs' cooperative synergy effect would be important to Sachungwhan(SC)'s effects mentioned in this paper.

This research examines the effect of globalization of Korean economy on small and medium-sized entrepreneurial firms. When Korea underwent the Asian economic crisis in 1997, it reconstructed Korean venture industry and had helped fuel venture firms' rapid growth. Therefore, this study shows the changed structure of Korean economy and the change of venture ecosystem due to the Asian financial crisis. In spite of a favorable turn of the industrial structure toward venture firms, their globalization level is reported still being low. In this study, we also examine how the Korean economy's globalization affects to the venture environments, focusing on the degree of Korea venture's globalization and role of venture capital. This study indicates that the globalization of Korean economy has played a positive role in the growth of the venture firms. However, with the growth of venture firms, small and medium venture companies have received relatively little focuses in Korean economy because the government policy of economic development has been oriented to large companies for several decades.

영상의 군집 속에서 특정 영상을 분류하기 위해서는 주로 목표 영상과 배경의 명암 차이를 구하는데 만약 특정 영상의 윤곽선이 흐리고 선명도가 낮다면 이를 분류하기가 쉽지 않다. 하지만 이러한 영상을 분류하기 위한 연구들이 많지 않으며, 지금까지 발표된 방법들을 적용하더라도 제대로 구분하지 못한다는 어려움이 있다. 본 논문에서는 각 3차원 필름 영상들의 히스토그램을 구한 후, 히스토그램의 최고 빈도를 기준으로 특정 빈도에서의 폭을 구하여 윤곽선이 흐린 불량패턴의 영상을 분류하는 방법을 제안한다. 실험을 통하여 정품 패턴과 불량 패턴 영상의 히스토그램 분포의 차이가 뚜렷하다는 것을 확인할 수 있었으며, 이러한 히스토그램의 특성을 반영한 제안 알고리즘을 통하여 모든 영상들을 정확하게 분류할 수 있다는 것을 보였다. 제안한 알고리즘의 성능을 평가하기 위하여 이진화, 히스토그램, 가장자리 검출을 이용한 각각의 유사도 검정들과 퓨샷 러닝의 분석 결과를 비교분석 하였으며, 실험을 통하여 제안한 알고리즘은 앞선 네 가지 방법들보다 복잡한 계산 없이 높은 성능을 낼 수 있다는 것을 검증하였다.

이형구와 포스트휴먼의 조건, 시선의 모빌리티

이재은(Lee, Jae-eun) 가천대학교 아시아문화연구소 2022 아시아문화연구 Vol.60 No.-

본 논문에서는 이형구 작업을 토대로 포스트휴먼 조건에서 시선의 모빌리티의 역할을 고찰했다. 이형구는 한국 포스트휴먼 미술의 선구자다. 시선의 모빌리티는 그의 작품을 관통하는 주요한 방법론 가운데 하나다. 이형구의 작업에서 말하는 시선의 모빌리티란 (인간) 주체의 시선의 방향이 우연을 따라 대상에서 일어나는 정동에 의지한다는 것을 의미한다. 물질의 정동을 따라가는 과정에서 그는 인간의 의지가 지배하는 특별한 원인과 결과 간의 관계를 벗어나 단지 상황적 지식이 일어나고 사라지는 ‘생동하는 물질’에 도달할 수 있었다. 결국에 시선의 모빌리티는 동물, 식물, 유기체, 기후 시스템, 기술 혹은 에코 시스템처럼 비인간을 배제해 온 인간 중심 사회에 반하는 운동을 이끌어 낸다. 요컨대 이형구의 작업은 인간 활동 중심으로 구축된 시스템을 넘어서 인간과 비인간의 대칭적 관계에 도달하기 위해서 정동을 따른 시선의 모빌리티의 필요성을 말해준다. 본 논문은 이형구의 작업에 나타난 시선의 모빌리티가 어떻게 인간과 비인간의 공존을 모색하는 과정에 관계하는 포스트휴먼의 조건으로 작동하는지를 논할 수 있는 기회를 제공했다는 점에서 의미가 있다. This paper examined, based on the work of Hyunggu Lee, the role of the mobility of gaze in the posthuman condition. Hyungkoo Lee is a pioneer of posthuman art in Korea. The mobility of gaze is one of the main methodologies running through his body of work. The mobility of gaze in Hyungkoo Lees work implies that the direction of the (human) subjects gaze depends on the affect that occurs in the object by chance. In the process of following the affect of matter, he was able to get out of the specific, dichotomous relationship between cause and effect, which is dominated by human reason and will, and arrive at ‘vibrant matter’ where only situational knowledge arises and disappears. Ultimately, the mobility of gaze leads to a movement against human-centered societies that have excluded non-humans, such as animals, plants, organisms, climate systems, technologies or eco-systems. In short, Hyungkoo Lees work demonstrates the necessity of the mobility of gaze that is true to affect in order to reach a symmetrical relationship between humans and non-humans beyond the conventional systems built around human activities. This paper is significant in that it has provided an opportunity to discuss how the mobility of gaze in Hyungkoo Lees work works as a condition for posthuman pertaining to the process of seeking the coexistence of humans and non-humans.
