Background and Objective : There are a lot of theories that explained the aging process, and the oxidative stress is one of the important theory that explained the aging process. The aim of this study was to investigate active oxygen and antioxidant capacity of Qi deficiency and Blood deficiency animal models. Material and Methods : Sprague-Dawley rats were divided into three groups: normal group, Qi deficiency group and Blood deficiency group. The Qi deficiency animal model was induced through restriction of food (12g/kg/day) for 20 days. Blood deficiency animal model was induced by bleeding from tail vein(0.4ml/time) 8 times. The normal animal model was kept without any intervention. The oxidative stress was observed by measuring the active oxygen and antioxidant capacity. Results and Conclusion : 1. Active oxygen was significantly increased in the Qi deficiency group and Blood deficiency group. (P=0.061) 2. Antioxidant capacity was increased in the Qi deficiency group and Blood deficiency group. But there is no significant difference. (P=0.113)

A PVA-soft hydrogel, which is a semi-solid form in container, whereas after applying on the skin, it formed a thin layer within a few minutes. In this study, we prepared a novel type PVA-soft hydrogel containing 6-methyluracil as active drug, and the therapeutic value was characterized. To evaluate the therapeutic value of the PVA-soft hydrogel containing drug, various animal models, thermal burn model, incision & excision wound rat model were used. We also measured the wound size and breaking strength to calculate the wound healing extent after single or multiple administration. The wound size of soft hydrogel treated group decreased rapidly than that of control group after multiple dosing in excision wound model. And, the breaking strength of the soft hydrogel treated group was greater than that of control group in incision wound model.

The errors in orthognathic surgery can occur during the preoperative preparations including the model surgery, but till now there's been some lack of reserches about them. So we wanted to verify the accuracies in measurements used in model surgery. We compared the accuracy of measurements by vernier calipers, which has been the main measurement tool for conventional model surgery, and that by height gauge, which is recently claimed to be more accurate, with 3 dimensional coordinate analyzer. We could have following results and have a plan to use them for the invention of new model surgery techniques. 1. The measurement errors in Group 1, which mean the difference between "the measurements by 3-D analyzer"and "the measurements by height gauge", were small enough with the range of $0.1{\sim}0.2mm$ in all planes. 2. The mean error in Group 2, which is the differences between the measurements of 3-D analyzer and those of vernier calipers, was 1.1mm. 3. The measurement errors in Group 2 were variable according to the factors including the differences of individuality and expertness of each measurers. But in case of Group 1, they were small and not variable by the expertness. 4. The measurements were more accurate at the points in anterior teeth than in molar teeth in Group 1 and 2. 5. The errors after model surgery increased remarkably, compared with those before surgery in Group 2. And the situation was different in Group 1 in that errors decreased after surgery. According to these results, it assumed that the measurements with height gauge during the model surgery for orthognathic surgery are accurate enough and can be maintained, regardless of complexity of models, individuality, or expertness of measurers.

The purpose of this study was to identify the differences n preference of advertisement and intention to buy the advertised jeans among the consumer groups which perceived eroticism and attraction of female model in advertising differently. he data were collected using questio-nnaires which contained eleven advertisements of Guess jeans selected form Vogue magazine publ-ished from 1990 to 1996. Female college students (n=270) living in Seoul Korea participated in the study. The data were analyzed by one-way ANOVA. he results of this study were as follows:First there were significant differences in preference of advertisement and intentio to buy the advertised jeans among the consumer groups which had different perceptions of eroticism and attraction of model in the case of eleven advert-isements. Second consumer group which perceived model erotic and attractive highly had the most preference of advertisement and intention to buy the advertised jeans, However consumer group which perceived model low in two aspects had the lowest preference and intention to buy. Third consumer group which perceived model a low erotic but highly attractive women had a higher preference of advertisement and intention to buy the advertised jeans than consumer gorup which perceived model a highly erotic but low attractive women or the former group was similar in prefe-rence and intention to buy to the latter group.

The purpose of this study was to develop the NCS-based cooking practice education method by using the full learning model and to confirm its effect. The study design was a pre-post test of the non-equality control group. The subjects of this study included 28 students in the experimental group and 27 students in the control group. The experimental group participated in the NCS-based cooking practice training using the complete learning model, and the control group received only cooking practice training based on the full learning model. The data were collected during the second semester of 2016 and analyzed by SPSS WIN 23.0. The results of this study were as follows: First, homogeneity test showed that pre - homogeneity such as general characteristics, cooking ability, and knowledge of cooking theory were achieved (p>0.05). Second, the experimental group recognized that its cooking ability was high. With respect to the ability to cook food, the ability to cook, and the ability to prepare food ingredients (p<0.01), personal hygiene management, cooking hygiene management, and cooking safety management abilities were not significant. The mean value the experimental group was high. Third, the final theoretical knowledge score was not significant. The average score in the experimental group (69 points) was 5 points higher than that in the control group (64 points). This was about two times higher than the score of 37 points in the first stage preliminary survey. Finally, the final performance score was significant (p<0.05), and the score in the experimental group (89 points) was 5 points higher than that in the control group (84 points). Therefore, the NCS-based cooking education method is confirmed to be an effective method, especially for improvement of the practical ability, improvement of theoretical knowledge, and achievement of perfect learning standards.

이 연구는 자연스러운 소집단 탐구 맥락에서 형성된 집단의 고유한 규범을 밝혀내고, 소집단 규범이 과학적 모형 구성에 미치는 영향을 알아보는 것을 목적으로 한다. 이를 위해 학생들의 상호작용을 잘 드러낼 수 있는 심장 혈액 흐름의 모형 구성 수업을 개발하였고, 서울 소재 중학교 2학년을 대상으로 수업을 진행하였다. 이 가운데 임의로 10개의 소집단을 추출하여 학생들의 담화와 활동을 녹음하고 비디오 촬영을 하였다. 수집한 자료는 먼저 집단의 상호작용 유형을 분류하였고, 각 유형을 대표적으로 보여주는 5개 집단에서 나타나는 규범과 모형의 특징을 분석하였다. 연구 결과, 집단마다 다양한 상호작용 유형을 보였으며, 소집단에서 구성한 모형의 질과 협력 및 모형 구성을 위한 규범 또한 집단마다 다르게 나타났다. 동일한 교사의 지도를 받는 탐구 맥락에서 학생들이 동일한 과제를 진행한다고 하더라도, 각 집단의 인지적인 책임감, 정당화에 대한 필요성, 협력과 참여, 멤버십에 대한 규범이 바탕이 되어 집단마다 다른 담화와 행동을 보였다. 또한, 한 집단을 제외하고, 모형 구성을 위한 인지적 책임감과 정당화와 같은 규범은 잘 발달하지 않았다. 이러한 규범은 궁극적으로 집단 모형 구성에 영향을 미쳤다. 구성원들의 적극적인 참여를 독려하여 협력을 촉진하고, 인지적 책임감을 가지고 자신의 의견을 정당화하면서 모형 구성을 촉진하는 규범을 형성하고 있는 집단은 구성원들의 추론적 사고를 촉발하였고 보다 목표 모형에 가까운 집단의 공동 모형을 구성하였다. 이 연구 결과는 소집단 활동을 통한 학습을 촉진하는 교실 환경을 구축하고, 이와 관련된 교사 교육 방안을 모색하는데 시사점을 제공한다.

본 논문에서는 분산 환경에서 TMO(Time-triggered Message-triggered Object) 기반의 객체그룹 모델을 구축하고, 본 모델을 적용한 분산 실시간 옹용 시뮬레이터를 개발하여 제공된 객체그룹 모델의 분산 실시간 서비스에 대한 수행성을 분석 및 평가한다. TMO는 실시간 특성을 자체적으로 갖는 실시간 서버객체이다. TMO 객체그룹의 정의는 네트워크상에 물리적으로 분산된 하나 또는 그 이상의 TMO들을 주어진 분산응용에 따라 논리적으로 재구성한 객체들의 집합이다. 이들 서버객채들의 그룹관리를 지원하기 위해, 제안한 TMO 기반의 객체그룹 모델은 임의의 객체그룹에 서버객체를 그를 구성원으로 등록/탈퇴 및 클라이언트로부터 서버객체의 접근권한의 추가/삭제 기능을 제공한다. 또한, 우리 모델은 단일뿐 아니라 중복 TMO들에 대한 적정객체 선정 및 동적바인딩 서비스를 지원하고, 실시간 객체인 TMO로부터 서비스를 요청하는 클라이언트들에 대한 실시간 스케줄링 서비스를 지원하도록 설계 및 구현되었다. 마지막으로, 본 모델을 적용하여 분산 실시간 응용의 한 예인 적기침입방어시스템(Defence System against Invading Enemy Planes, DSIEP) 시뮬레이터를 개발하고, 이로부터 TMO 기반의 객체그룹 모델이 제공할 수 있는 그룹 구성요소들에 대한 분산 서비스 정책들의 적응성과 실시간 서비스의 수행성을 분석하였다.
