The purpose of this study is to analyze the effect of college sport club participants Social Support on the College Adjustment. To accomplish the purpose, 360 participants were sampled by means stratified cluster random sampling method. only 317 questionnaires were statistically processed, while 43 questionnaires were excluded because their respondents failed to complete instrument and judged insincere in filling out questionnaire. To analyze the data collected, statistical techniques, such as Descriptive Staistics, Reliability Analysis, Independent-sample t-test, and one-way ANOVA, multiple regression Analysis were used, and as for difference verification between individual groups in relation to significant results, Duncan’s multiple range was conducted.The study hypothesis was verified through the above research method and procedures and the following results have been drawn out. First, the background variable of the college sport club participants of was proved to affect th degree of their ego-resilience and social support on the college adjustment. Specifically, their period of participation, frequency of participation and expenses made a statistically meaningful. Second, the college sport club participants of social support was proved to affect the college adjustment. Specifically, social adjustment, personal-emotional adjustment and institutional attachment made a statistically meaningful difference.

본 연구에서는 사망 및 투자수익률의 확률론적 방법에 기초한 시나리오를 통해서 개인이 연금 대신 대안투자(자가연금)를 선택하였을 경우에 발생할 수 있는 파산확률과 손실금액을 산출하였고, 파산확률과 손실금액을 고려하여 이를 장수리스크로 정의하였다. 기존의 연구는 파산확률을 고정된 생존확률에 의존하여 산출하였고 부족금액이 발생한 시점의 부족금액을 리스크량으로 정의하였으나, 본 연구는 베르누이 분포를 이용하여 실제 사망의 분포를 산출하여 사용하였으며 각 사망 시점에서 손실금액을 평가하여 이를 리스크량으로 계량화하였다. 기존 연구는 단순히 확률에만 관심 있었다면 본 연구는 실제 확률론적 방법을 적용하였고 사망시점의 리스크량 평가까지 확대한 것에 의의가 있다. 또한 확률론적 방법에 의한 투자P/F별로 최적의 연금개시 연령을 제시하였다. In this study, we calculated the ruin probability that could occur when individuals choose self annuity plans instead of conventional annuity, based on the actual mortality rate and investment return scenarios. We defined this as longevity risk by considering both the ruin probability and the maximum loss amount. Previous research calculated the ruin probability based on fixed survival probabilities and defined the shortfall amount at the point of occurrence as the risk amount. However, in this study, we used the Bernoulli distribution to estimate the distribution of actual ages at death and quantified the loss amount at each death point as a measure of risk. While previous research was solely interested in probabilities, this study applied actual probabilistic methods and expanded the evaluation to include the risk amount at the time of death. Furthermore, we provided the optimal retirement age for each investment portfolio based on the probabilistic approach.

This study was conducted to determine the effects of using mechanically deboned chicken meat (MDCM) and collagenon quality characteristics of semi-dried chicken jerky. In experiment I, semi-dried chicken jerky was prepared with thereplacement of chicken breast with MDCM (0, 10, 20, and 30%). The pH value of the jerky formulated with only chickenbreast was 5.94, while the replacement of chicken breast with MDCM significantly increased the pH (p<0.05). The proteincontent and shear force of the jerkies decreased with increasing amounts of MDCM, whereas the fat, ash content and pro-cessing yield showed the opposite tendency (p<0.05). Replacement with up to 10% MDCM had no adverse effects on thesensory characteristics of the semi-dried chicken jerky. In experiment II, four levels of pork collagen (0, 1, 2, and 3%) wereadded to the semi-dried chicken jerky formulated with 90% chicken breast and 10% MDCM. The addition of collagenincreased the moisture content, but decreased the ash content of the jerkies produced (p<0.05). The processing yield of thejerkies increased with increasing added amounts of collagen (p<0.05). It was found that the jerkies formulated with 0-2%collagen had significantly higher overall acceptance score than those prepared with 3% collagen (p<0.05). In conclusion,MDCM and collagen could be useful ingredients to reduce the production cost and improve the processing yield of semi-dried chicken jerky. The optimal levels of MDCM and collagen which could be added without adverse effects on the sensorycharacteristics were up to 10% and 2%, respectively.

The combined effects of smoking and boiling on the proximate composition, technological quality traits, shear force, and sensory char- acteristics of the Korean traditional boiled loin were studied. Cooking loss, processing loss, and shear force were lower in the smoked/ boiled samples than those in the control (without smoking treatment) (p<0.05). The results showed that the boiled loin samples between the control and treatment did not differ significantly in protein, fat, or ash contents, or pH values (p>0.05). The treated samples had higher score for overall acceptability than the control (p<0.05). Thus, these results show that the Korean traditional boiled loin treated with smoking for 60 min before boiling had improved physicochemical properties and sensory characteristics.

Objectives The purpose of this study is to improve the accessibility of Korean medicine by standardizing managements, improving quality of medical services, and reducing medical costs in ankle sprain by develop clinical pathway (CP). Methods The development of CP in this study is based on clinical practice guideline (CPG) for ankle sprain, and aims to maximize the quality of treatment, such as reducing treatment time and medical costs, and increasing patient satisfaction through standardized pathway. The CP was revised after consultation and review by the advisory committee. The advisory committee is consisted of a stakeholder group applying the CP. Results In previous research studies, there were no Korean medicine CP studies on ankle sprain. Based on CPG for ankle sprain and analysis of medical records, 6 types of time task matrix type CP (for Korean medicine doctors, medical assistant, patients) and 4 types of algorithm type CP (for Korean medicine clinics, Korean medicine hospitals, and cooperative practicing hospitals, public medical centers) were derived as a result. Conclusions Ankle sprain CP is expected to not only increase patient satisfaction and maximize the quality of treatment, but also reduce the financial burden of health insurance by reducing medical costs.
