이 연구의 목적은 뇌성마비 아동에게 앉은 자세에서 현수를 이용하여 체중지지를 해주었을 때 상지기능에 어떠한 영향을 미치는지 알아보는 것이다. 연구대상자는 뇌성마비 아동 5명과 뇌종양 아동 1명이었다. 연구대상자에게 harness를 착용하여 부분적 체중지지를 하기 전과 착용한 상태에서 손 뻗기 동작을 3차원 동작분석기를 이용하여 어깨관절과 손뻗기 동작에 걸린 시간을 측정하였고, Box and Block 검사를 실시하여 체중지지 전과 착용 시 상지 기능을 비교하였다. 자료분석은 윌콕슨 부호순위검정을 사용하였다. 어깨관절의 관절 가동범위와 Box and Block 검사에서는 유의한 차이가 없었으나, 팔뻗기 동작의 수행 시간에는 유의한 차이가 있었다(p<.05). 연구 대상자의 수가 적고, 대상자 마다 연령 및 손상의 정도가 서로 다르기 때문에 연구결과를 일반화하여 해석하기에는 제한점이 있지만, 앉은 자세에서 harness를 이용하여 부분적 체중지지를 적용하였을 때 상지의 기능 향상에 도움을 줄 수 있으리라 생각하며 향후 다수를 대상으로 한 연구가 필요하리라 생각한다.

A wind tunnel test of 29.7% scaled model of NASA Common Research Model with belly model support was performed in small low speed wind tunnel. The static aerodynamic forces and moments of CRM were measured with belly sting support configuration. Pitching moments of belly sting with various fairings were compared and small interference fairing shape was found. The belly sting model support interference and reducing effect of fairing shapes with CFD analysis.

Computational Fluid Dynamics (CFD) was performed under low-speed wind tunnel test conditions using a 29.7% scale model of the NASA common research model. A wind tunnel test was conducted to measure the aerodynamic coefficient of the CRM with Belly sting model support configuration at a low Reynolds number of 0.3×106 and it was compared with the aerodynamic coefficient of CFD analysis. In order to verify the validation of the analysis, a computational analysis under the conditions of the advance research was performed and compared. The interference effect of the Belly sting model support affected not only the fuselage but also the main and tail wings.

The purpose of this research is to identify internal and external factors that affect specialized technical high school students' career decision status. It then uses career decision types to predict the variables which have the impact on emotional aspects of specialized technical high school student who feel comfortable or uncomfortable after career decision in order to help specialized technical high school students choose their career. The subject of this study consist a total of 809 male and female students attending specialized technical high school located in South Korea. Data were analyzed to investigate the types of career decision status of specialized technical high school students using the SPSS 21.0 program. The results obtained through the study were as follows. Types of career decision status of specialized technical high school students were divided into four groups based on career decision status and types of emotional state. Results showed the decision-comfort(51.3%), decision-discomfort(25.6%), indecision- discomfort(15.3%), indecision-comfort(1.3%) in order. Social support were selected as variables affecting the comfort and discomfort of two groups and the determining factor which distinguished four groups. Result of the analysis showed that social support has statistically significant impact on whether it was decision or not and comfort or not. But career decision-making self-efficacy has no big impact on career decision types. Taking all results of this study together, we can see that specialized technical high school students feel comfortable and they decide the career, but still many students feel uncomfortable on their decision after deciding their career. It suggests the need of development and operation of program about emotional status of career decision which can help specialized technical high school students prepare their career comfortably after they decide on the career, and the need of segmented career counseling approach including social support group.

The purpose of this study is to propose safety factors of pile bearing capacity based on the reliability analysis. Each prediction method involves various degrees of uncertainties. To account for these uncertainties in a systematic way, the ratios of the measured bearing capacity from pile load tests to the predicted bearing capacity are represented in the form of a probability density function. The safety factor for each design method is obtained so that the probability of pile foundation failure is less than 10-3. The Bayesian theorem is applied in a way that the distribution using static formulae is assumed to be the A-prior and the distribution using dynamic formulae or wave equation based methods is assumed to be the likelihood, and these two are combined to obtain the posterior which has the reduced uncertainty. The results of this study show that static formulae of the pile bearing capacity using the 5.p.7. N-value as well as dynamic formulae are highly unreliable and have to have the safety factor more than 7.4 : the wave equation analysis using PDA(Pile Driving Analyzer) system the most reliable with the safety factor close to 2.7. The safety factor could be reduced certain amount by adoption the Bayes methodology in pile design.

This research was conducted to investigate the structural relationship social support of college students has with their occupational values, career decision, and quality of life. Subjects of study were art and design college students in Seoul. Social support, occupational values, career decision, and quality of life were measured as criteria. SPSS and AMOS were used to test structural model and the relationship among variables. Results of this study are as follows. First, effects of social support on internal and external occupational values were studied. Second, effects of social support on quality of life-satisfaction and happiness-were studied. Third, effects of occupational values on career decision standards were studied. External occupational values had a statistically significant correlation with career decision, while internal occupational values were found to have no statistically significant effect on career decision. Based on the results, it can be inferred that colleges which need to support the careers and employment of students must support students with informational and instrumental support. Design students must be provided with proper career coaching and environment improvement, as well as development of programs suitable for various talents and aptitudes, so that they can shape appropriate occupational values.

수정된 기체투과법을 이용하여 다공성 지지체의 기공크기를 평가하였다. 본 연구에서의 수정된 기체투과법은 기공 내에서 유체흐름이 Hagen-Poiseiulle 법칙이 성립하는 영역으로 압력을 조절하여 투과유량을 측정하는 방법을 말한다. 수정된 기체투과법의 적합성 여부는 유체의 Reynolds number 및 기체분자의 평균자유행로를 통해 검토하였다. 다공성 지지체의 유량의 시간변화로부터 대표치를 결정하여 기공크기로 환산하였다. 본 방법에 의해 평가된 다공성 지지체의 기공크기는 30$\mu\textrm{m}$~80$\mu\textrm{m}$ 이었으며, 평균치는 50$\mu\textrm{m}$로 평가되었다. 한편 화상해석법과 비교.분석한 결과 수정된 기체투과법을 통해 평가된 기공은 내부채널의 가장 작은 부분을 나타내는 것으로 확인되었다.

This paper presents the finite element analysis results for bearing loads and stress distributions of safety helmets with an extruded structure. Five different analysis models with given same displacement load of 9.4mm have been analyzed for bearing loads and maximum von Mises stress. In these models, model 4 and model 5 are recommended as a maximum bearing load and low maximum stress for given displacement load of 9.4mm.

The purpose of this study was to investigate the actual conditions of successful ageing and the influencing factors focusing on social support from family and friends to improve elderly's quality of life. The 300 respondents, all participants in programs at facilities for the elderly, were interviewed via a questionnaire. The collected data were analyzed using SPSS 23.0. The results are as follows. First, the average score for successful ageing among the participants was above average. Second, the level of successful ageing varied according to income and religion. Third, the common variables affecting active or emotionally successful ageing were support from friends, subjective health conditions, and gender. It is suggested that the community should be informed of the importance of support from family through educational programs, as the elderly still want the support of family despite family's reduced role.
