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.

This study aims to identify unique small group norms and their influence on the process of constructing a scientific model. We developed instructional materials for the construction of a model of blood flow in the heart and conducted research on eighth-grade students from one middle school. We randomly selected 10 small groups, and videotaped and recorded their dialogues and behaviors. The data was categorized according to the types of interaction and then analyzed to investigate the characteristics of group norms and models in one or two representative groups for each type. The results show that the types of interaction, the quality of the group models, and the group norms were different in each group. Even though one teacher guided students through the same task in the inquiry context, each group revealed different patterns of discourse and behavior, which were based on norms of cognitive responsibility, the need for justification, participation, and membership. With the exception of one group, there was little cognitive responsibility and justification for students' opinions. Ultimately, these norms influenced the model construction of small groups. A group that forms norms to encourage the active participation and justify members' opinions with cognitive responsibility was encouraged to do inferential thinking and construct a group model close to the target model. This study has instructional implications for the establishment of a classroom environment that facilitates learning through small group activities.

In this paper, we construct the TMO-based object group model on distributed environment, and analyze and evaluate the executability for distributed real-time service of our object group model by developing the distributed real-time application simulator applying the model. The Time-triggered Message-triggered Object(TMO) is a real-time server object having real-time property itself. The TMO-based object group is defined as a set of objects which logically reconfigured the physically distributed one or more TMOs on network by a given distributed application. For supporting group management of the server objects, the TMO-based object group we suggested provides the functions which register and withdraw the solver objects as a group member to an arbitrary object group, and also provides the functions which insert and delete the access rights of server objects from clients. Also, our model was designed and implemented to support the appropriate object selection and dynamic binding service for a single TMO as well as the duplicated TMOs, and to support the real-time scheduling service for the clients which are requesting the service. Finally, we developed the Defence System against Invading Enemy Planes(DSIEP) simulator as a practical example of distributed real-time application by applying our model, and evaluated the adaptability of distributed service strategies for the group components and the executability of real-time services that the TMO-based object group model provides.
