In this paper, we characterize and analyze the technology elements and their hierarchy for the college graduating students performing capstone design projects in a game software major. When graduating students in a game software major must make a game for graduation, they need to know the pertinent technologies and their hierarchy. Technology analysis for game making would mean for students to recognize how the low level technologies taught in freshman and sophomore periods are linked to the high level technologies taught in junior and senior periods. Also, the analysis would help the professors design the game software major curriculum in detail based on the levels and the hierarchy of the individual technologies.

This study investigates the response of functionally graded (FG) gas pipe under unsteady internal pressure and temperature. The pipe is proposed to be manufactured from FGMs rather than custom carbon steel, to reduce the erosion, corrosion, pressure surge and temperature variation effects caused by conveying of gases. The distribution of material graduations are obeying power and sigmoidal functions varying with the pipe thickness. The sigmoidal distribution is proposed for the 1st time in analysis of FG pipe structure. A Two-dimensional (2D) plane strain problem is proposed to model the pipe cross-section. The Fourier law is applied to describe the heat flux and temperature variation through the pipe thickness. The time variation of internal pressure is described by using exponential-harmonic function. The proposed problem is solved numerically by a two-dimensional (2D) plane strain finite element ABAQUS software. Nine-node isoparametric element is selected. The proposed model is verified with published results. The effects of material graduation, material function, temperature and internal pressures on the response of FG gas pipe are investigated. The coupled temperature and displacement FEM solution is used to find a solution for the stress displacement and temperature fields simultaneously because the thermal and mechanical solutions affected greatly by each other. The obtained results present the applicability of alternative FGM materials rather than classical A106Gr.B steel. According to proposed model and numerical results, the FGM pipe is more effective in natural gas application, especially in eliminating the corrosion, erosion and reduction of stresses.

Purpose: The purpose of this study was to develop extracurricular coaching programs to improve communication skills and leadership for nursing students and evaluate the effects of the programs. Methods: The 8-week extracurricular coaching program was developed based on the Joo, Whitmore and Hong models. A quasi-experimental design was used. The subjects were selected by two full-time nursing professors training students at one university in city G. The subjects were chosen from among the advisees of these two professors. Of the students who participated in this study, 29 were in the experimental group and 27 were in the control group. Data was analyzed through t-test and Mann Whitney U-test. Results: The experimental group showed significantly higher post-test scores in communication skills, communication as a nursing outcome, observation of communication, leadership, and leadership as a nursing outcome than those of the control group. However, the experimental group did not reveal significantly higher post-test scores in the number of leadership activities using a portfolio than those of the control group. Conclusion: This extracurricular coaching program can help cultivate important, basic grounding as well as achieve nursing student learning outcomes upon graduation.

The purpose of this study was to explore college students' expectations on post-college housing and sources of finance to afford housing costs; and perception of housing cost burden. Between May 28, 2012, and June 17, 2012, a questionnaire survey was conducted to undergraduate students in university-A located in non-capital region and 465 useable responses were collected. Major findings are as follows: (1) About 60% of respondents expected to live apart from their parents or relatives within two years from college graduation; (2) Majority of respondents who expected to live apart from their parents or relatives expected to rent housing units and compact non-traditional housing types such as studio units; (3) Major source of finance the respondents expected to afford post-college housing costs was financial supports from their parents and families; (4) Housing cost burden were perceived to have influence even on job decision and respondents with lower parents' income perceived housing cost burden more influential; and (5) In spite of respondents' low financial independence to afford post-college housing costs, finding housing units in areas with relatively lower housing costs seemed not to be an important consideration when choosing post-college housing.

The basic understanding of gas diffusion and technology to predict the diffusion phenomena are needed to prepare against a disaster of leakage of natural gas and to design better consistent and reliable gas supply system in enclosure. The experimental results of British Gas Technology Co. are used in present study as a reference of theoretical study using CFD. The present results of 2D CFD analysis for mass flow rate of nozzle release show good agreement with experimental results within 2.6 % error. 3D CFD analysis for the characteristics of natural gas diffusion in enclosure with various ventilation patterns also gives reasonable agreement with experimental results.

This study aims at seeking the effective career guidance and operational plan. We collected data from questionaries to 305 students of vocational school, and 135 students on vocational course for the recognition of and request for vocational home economics curriculum. Collected data were analysed by frequency, percentage, and X(sup)2, and SPSS/PC(sup)+ program are used for the statistical analysis. 1. The main considerations of students in their decision of course were the accessibility of getting a job, or a higher education aptitude, interest, and so on. They made their own decision in choosing their course, relatively were satisfied with their choices. As for the course after graduation they hoped to come by a job related to their major in order to have3 an opportunity for further education, and teachers stood up for the large extent to which their students are satisfied with vocational training by answering that there would be higher possibility of using their major. 2 The results of the investigation into the desirable home economics vocational training in future showed that students of vocational schools desired for the scientific teaching and learning method. Students on vocational curse requested that the educational system should be supported. And new curricula were those for gerontology. interior design, and cookery and bakery.

Purpose: This study was done to examine factors affecting quality of life among community-dwelling elderly women who live in rural areas. Methods: The design of this research was cross-sectional descriptive study. The participants were 92 community-dwelling women aged 65 or older. Data were collected from November 1 to 15, 2013. ADL (Kart's Index), GDS-SF (Geriatric Depression Scale Short Form) and GQOL (Geriatric Quality of Life Scale) were used to measure variables. Data were collected using self-administered questionnaires and analyzed using descriptive statistics, Spearman's coefficient and stepwise multiple regression. Results: The participants' mean age was 77.5, and 85.9% had elementary school graduation or less education, and for 64.1%, their economic status was low. Spearman's rho coefficient analysis found that QOL was significantly associated with depression (r=-.72, p<.001), perceived health (r=.58, p<.001), regular exercise (r=.47, p<.001), education level (r=.29, p=.005), and ADL (r=-.21, p=.043). Multiple regression analysis showed that 65.9% of their QOL was explained by depression (${\beta}=-.72$), perceived health (${\beta}=.24$), ADL (${\beta}=-.16$), exercise (${\beta}=.22$) and number of diseases (${\beta}=.19$). Conclusion: These results indicate that older women who live rural areas need support for ADL, and prevention of depression to improve their quality of life.

In this study, improvements of university education are suggested so that university graduates can work in plant engineering industry without major retraining which is required in plant engineering companies. Before disposition of manpower to the plant engineering site, new recruits are retrained by the company for about 2~3 years, since university education is not sufficient and appropriate to handle plant engineering tasks. It is urgent to integrate into university education practical plant engineering that can be used effectively after graduation. In case of S2 University located in Seoul, it is enough to supplement interdisciplinary program to plant engineering subjects if proper texts are developed. To replace plant engineering education offered by the company with the university education, following measures should be taken. First, basic plant engineering should be taught for 15 hours. Second, education on design and drawings should be reinforced.
