The awareness of education service is undergoing a transition from demand side to supply side. This study 1) develops an evaluation model of education service composed of three core factors(curriculum content, professor activities, job search activity) and additional factors(public welfare, education environment, campus life), 2) verifies a model using the structural equation model, 3) calculates the satisfaction measurement index of education service, and 4) proposes the results of IPA for evaluating the satisfaction measurement of education service. The results show significant notions that core factors(curriculum content, professor activities, job search activities) and additional factors(public welfare, education environment, campus life) determine students satisfaction, and that student satisfaction effects the recommend purpose significantly. Especially, student satisfaction influenced curriculum content, job search activity, campus life, public welfare, professor activities, education environment in order. This study provides improved strategic implications based on the calculated results of component satisfaction measurement index, and the results of IPA.

Background: Human skin undergoes distinct changes throughout the aging process, based on both intrinsic and extrinsic factors. In a process called photoaging, UVB irradiation leads to upregulation of matrix metalloproteinase-1, which then causes collagen degradation and premature aging. Mixtures of medicinal plants have traditionally been used as drugs in oriental medicine. Based on the previously reported antioxidant properties of Panax ginseng Meyer and Crataegus pinnatifida, we hypothesized that the mixture of P. ginseng Meyer and C. pinnatifida (GC) would have protective effects against skin aging. Methods: Anti-aging activity was examined both in human dermal fibroblasts under UVB irradiation by using Western blot analysis and in healthy human skin by examining noninvasive measurements. Results: In vitro studies showed that GC improved procollagen type I expression and diminished matrix metalloproteinase-1 secretion. Based on noninvasive measurements, skin roughness values, including total roughness (R1), maximum roughness (R2), smoothness depth and average roughness (R3), and global photodamage scores were improved by GC application. Moreover, GC ameliorated the high values of smoothness depth (R4), which means that GC reduced loss of skin moisture. Conclusion: These results suggest that GC can prevent aging by inhibiting wrinkle formation and increasing moisture in the human skin.

Objective: The present study was conducted to evaluate the effects of dietary supplementation with Bifidobacterium animalis, Agave fructans, and symbiotic of both encapsulated on growth performance, feed efficiency, blood parameters, and immune status in broiler chickens, and to compare these with diets including antibiotic growth promoters and without additives. Methods: A comparative experimental study was carried out with 135 male Ross 308 broiler chickens. Each trial was divided into 5 equal groups. Control group (CON) received a standard diet without growth promoter; GPA, a standard diet with colistin sulfate and zinc bacitracin (0.25 g/kg of feed); PRE, a standard diet with 1% Agave fructans; PRO, a standard diet with Bifidobacterium animalis (11.14±0.70 log CFU/g); SYM, a standard diet with B. animalis and Agave fructans. Results: A significant decrease in food consumption was found for the GPA, PRE, and SYM, compared to the CON group. The results show a better feed conversion index in PRE and GPA with respect to the CON group with the highest conversion index. Interestingly, the weight of the gastrointestinal tract shows a statistically significant difference between GPA and PRE groups. Moreover, the length of the gastrointestinal tract of the GPA group was less than the PRE group. In the total leukocyte count, there was a statistically significant increase in the GPA group compared to the CON, PRE, and PRO groups, and the heterophiles-lymphocytes index was lower in PRO. Regarding the cytokines, interleukin 10 (IL-10) decreased in PRO compared to CON and PRE, while IL-1β increased in the SYM group. Conclusion: Alternative treatments were shown to achieve similar productive results as growth-promoting antibiotics and showed improvement over diet without additives; however, they have immunomodulatory properties and improved the development of the gastrointestinal tract compared to the treatment of growth-promoting antibiotics.

This study attempted to survey nursing students' motives for choosing nursing as their major, and to examine how such motives affect their satisfaction with their major, campus-life satisfaction, and self-directed learning ability. This study was conducted as a descriptive survey. Data were collected using a self-report questionnaire during the period from the 1st to 15th of April, 2015, and the questionnaires from 195 nursing students were used in the analysis using Fisher's exact test, t-test, one way ANOVA, Mann Whitney test, and ANCOVA. Only 41.5% of the nursing students chose nursing as their major because of their aptitude and interest. The motive for the selection of the major was found to have a significant effect on their satisfaction with the major (p<.001), campus-life satisfaction (p=.008), and self-directed learning ability (p=.001). Middle and high school students should be provided with various types of information on nursing, so that they can have the opportunity to choose nursing based on their aptitude and interest before entering university. Once they start university, nursing students' adjustment to campus-life and learning ability should be enhanced through various extracurricular activity programs in order to stimulate their interest in the major.

The student group division is benefit for universities to do the student management based on the group profile. With the widespread use of student smart cards on campus, especially where students living in campus residence halls, students' daily activities on campus are recorded with information such as smart card swiping time and location. Therefore, it is feasible to depict the students with the daily activity data and accordingly group students based on objective measuring from their campus behavior with some regular student attributions collected in the management system. However, it is challenge in feature representation due to diverse forms of the student data. To effectively and comprehensively represent students' behaviors for further student group division, we proposed to adopt activity data from student smart cards and student attributes as input data with taking account of activity and attribution relationship types from different perspective. Specially, we propose a novel student group division method based on a multi-view student attribute heterogeneous information network (MSA-HIN). The network nodes in our proposed MSA-HIN represent students with their multi-dimensional attribute information. Meanwhile, the edges are constructed to characterize student different relationships, such as co-major, co-occurrence, and co-borrowing books. Based on the MSA-HIN, embedded representations of students are learned and a deep graph cluster algorithm is applied to divide students into groups. Comparative experiments have been done on a real-life campus dataset collected from a university. The experimental results demonstrate that our method can effectively reveal the variability of student attributes and relationships and accordingly achieves the best clustering results for group division.

Purpose: There has been a need to integrating the self-help program for arthritis with the TaiChi for arthritis patient. The purpose of this study was to develop and to examine the effect of the Self-help and Tai Chi for arthritis (SHTCA) program for arthritis. Method: This study was designed non equivalent control group pre-post test, quasi-experimental design. A total 40 participants were recruited in W-city, 29 participants(14-experimental group and 15-control group) completed post test. The experimental group participated in the SHTCA once a week for 8 weeks. SHTCA program was consisted of understanding of the arthritis, contracting of the promise, exercise for muscle strength and joint flexibility and 8 movements of Tai Chi exercise. Coloring plus program to cellular phone was used to encourage the exercise and participation by the KT-SHUT twice a week. Measures used to examine the effect of the SHTCA were EQ-5D standardized five dimensions(mobility, self-care, usual activities, pain & discomfort, and anxiety & depression), and health perception, joint flexibility, grasping power, and balance. Collected data was analyzed by SPSS WIN 14.0. Results: The experimental group had significantly increased the EQ-mobility(p=.033), health perception(p=.000), right shoulder flexibility(p=.007), and left shoulder flexibility(p=.002) compared to the control group. In addition, pain was decreased(p=.052) and right grip was increased(p=.052) after 8 weeks program in the experimental group. Conclusion: This SHTCA using coloring plus program was found partially effective and satisfactory. We recommended further research on the effect of this SHTCA effects.

The purpose of this study is to measure the relation of employment stress and self-esteem in some health college students and to consider a proper means for the solution. The population of the research is some randomly chosen health college students located in Seoul City during the period from May 10 to June 11 2010, and the sample of 295 students were recruited as the analysis object group. The data on general characteristics and employment stress were collected by a questionnaire survey. The collected data were analyzed with the SPSS WIN 12.0 program. The following shows the results of this study. 1. Employment stress was low in high group of satisfaction in campus life. It was statistically significant(p<0.001). 2. Mean scores of total self-esteem in study population were 3.1 and positive self-esteem level(3.76) were higher than negative ones (2.44)(p<0.001). 3. The relation between employment stress and selfesteem(r=0.132) revealed significant correlation. 4. In regression analysis, home economy, competence for a schoolwork, satisfaction in campus life, self-esteem(p<0.001) were proved as significant factors that is related to the employment stress. In other words, It is significant statistically that the lower home economy, competence for a schoolwork, satisfaction in campus life, self-esteem, the higher employment stress level. I suggest with the result of the study that for coping effectively employment stress of health college students, we will need to open an educational development considering self-esteem and an exclusive employment counsel window for better administrationwelfare service in campus, to expand industry-academic cooperation in community. Because of students are independent responsibility of employment, active effort must take precedence in order for the solution of problem by themselves. Also, we will need to create better academic environment and show more concern, consideration, love in family.

In recent years, human is experiencing an 'untact' era that has not been existed before. A remarkable features of an untact era is a limited or no interaction with other people and things in a daily life. In order to overcome this special situation, diverse state-of-the-art technologies like ICT technology are being used to give the effect of face-to-face and contact. In particular, Virtual Reality technology allows users to actively interact with virtual environments, objects, and other people, thereby providing effects that are as similar as possible to experience in real life. School freshmen are also experiencing various inconveniences because they are not experiencing the environment or academic management of newly admitted schools in the untact era. This research is a study and implementation of 'Virtual School Life Experience Content' which provides new students to tour campus, to utilize the school buildings facilities, to experience of academic schedules including course registration, and to participate in school events in an environment that is as close as possible to the real campus. Freshmen will be able to easily adapt to a new school through the implemented VR content.
