Purpose: The purpose of this study aims to provide a fundamental basis for more efficient human resource management of hospitals through career development and through lowering the rate of turnover of nurses. Method: The target group was 370 nurses who are currently employed at four general hospitals. Three hundred and twenty-nine documents were collected, and the statistical results were generated by the SAS program. Result: The average mean score of organizational commitment, career commitment and turnover intention were: 3.13 points for affective commitment, 3.09 points for continuance commitment and 2.92 points for normative commitment, out of a five point scale. The average mean score of career commitment and turnover intention was 2.89 and 3.28 points. The most influential variable in turnover intention was affective commitment out of organizational commitment. Conclusions: This study verified that organizational commitment and career commitment are key variables that could decrease turnover intentions.

Objectives: The main purpose of this study was to compare influencing factors on depression between male and female students at the high school. Methods: The self-administered questionnaire survey was carried out on a convenience sample of 403 high school students. The data analysis procedure included frequency, ${\chi}^2$ test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression using depression as the dependent variable. Results: There was a significant gender difference in depressive symptoms; the mean depression score of female students was higher than that of male students. Stepwise multiple regression analysis for depression revealed that the most powerful predictors (34%) were powerlessness and self-esteem for male students. On the other hand, the factors such as self-esteem, mother's occupation, and family fucntion were the most significant predictors (50%) for female students. Conclusion: The necessity of an intervention considering gender difference in high school students so as to prevent the occurrence of depression was suggested.

In the study of married couples, there has been a great lack of analysis of the factors affecting the marital satisfaction of spouses until now. In this study, the subjects were couples living in Seoul or Gyeonggi Province. The data collection period was November 20 to December 20, 2009, and data ond 184 couples were collected and used for the analysis. The SPSS 17.0 program was used for the analysis. The main findings of this study are as follows: First, the husbands' marital satisfaction was higher than that of the wives. And the variables of spousal support, alternative comparison level and marital dissolution disability were also found to be statistically significant according to gender. Second, it was confirmed that the self-variables had a greater effect than partner variables on couples' marital satisfaction. Third, the influential factors of the marital satisfaction of husbands and wives depended on the individual resource variables (self-esteem, health of origin of family, parenting efficacy), the couple relationship variables (spousal support, spousal similarity, recovery attempts), and the level of marital alternatives.

본 연구는 고령사회에 접어든 우리나라의 인구구조를 제고 하여, 중장년층의 저소득층들이 느끼는 삶에 대한 인식을 고찰하였다. 분석을 위하여, 보건복지부에서 제공하는 2019년 복지패널자료를 토대로 필요로 하는 변수를 선정하였고, 총 14,918명의 패널표본으로부터 '저소득층'의 '60대-70대' 중에서, 무응답 및 불성실한 표본을 제거하여, 최종 1,684명의 표본을 선정하였다. 특히, 본 연구에서는 종속변수로써, 패널자료에서 측정한 '삶의 사다리'로 정의하였다. 이에, '삶의 사다리'에 미치는 개인적 특성 및 생활만족도의 영향요인을 분석하였다. 분석결과, 종속변수인 「삶의 사다리」 변수에 대한 영향요인으로, 개인적 특성만을 고려하였을 경우에는, 대부분의 개인적 특성이 「삶의 사다리」의 영향요인으로 나타났다. 또한, 경제상태변수에 대한 상호작용 효과를 살펴본 결과, 유의미한 상호작용 효과를 나타내지 않았다. 이는 중년노인들의 삶의 사다리에 미치는 영향요인은 경제상태보다는 건강상태가 유의미한 영향요인임을 반증해주고 있다. 따라서, 노인의 '삶의 사다리'에 대한 인식은 노인 개인적인 여건과 환경보다는 노인의 내적 및 외적인 다양한 '환경요인'이 노인의 삶에 대한 인식에 영향을 미침을 제고 해야 한다. 즉, 그들의 삶에 대한 인식에 긍정적인 대안을 제시할 수 있는 방안이 필요할 것이다.

The development in data collection techniques results in high dimensional data sets, where discrimination is an important and commonly encountered problem that are crucial to resolve when high dimensional data is heterogeneous (non-common variance covariance structure for classes). An example of this is to classify microbial habitat preferences based on codon/bi-codon usage. Habitat preference is important to study for evolutionary genetic relationships and may help industry produce specific enzymes. Most classification procedures assume homogeneity (common variance covariance structure for all classes), which is not guaranteed in most high dimensional data sets. We have introduced regularized elimination in partial least square coupled with QDA (rePLS-QDA) for the parsimonious variable selection and classification of high dimensional heterogeneous data sets based on recently introduced regularized elimination for variable selection in partial least square (rePLS) and heterogeneous classification procedure quadratic discriminant analysis (QDA). A comparison of proposed and existing methods is conducted over the simulated data set; in addition, the proposed procedure is implemented to classify microbial habitat preferences by their codon/bi-codon usage. Five bacterial habitats (Aquatic, Host Associated, Multiple, Specialized and Terrestrial) are modeled. The classification accuracy of each habitat is satisfactory and ranges from 89.1% to 100% on test data. Interesting codon/bi-codons usage, their mutual interactions influential for respective habitat preference are identified. The proposed method also produced results that concurred with known biological characteristics that will help researchers better understand divergence of species.

A coupled algorithm is proposed which first considers the creation of porous structure of the material and then the simulations of response of mechanical components with porous structure to a variable load history. The simulations are carried out by the Prandtl operator approach in the finite element method (FEM) which enables structural simulations of mechanical components subjected to variable thermomechanical loads. Temperature-dependent material properties and multilinear kinematic hardening of the material can be taken into account by this approach. Several simulations are then performed for a tensile-compressive specimen made of a generic porous structure and mechanical properties of Aluminium alloy AlSi9Cu3. Variable mechanical load history has been applied to the specimens under constant temperature conditions. Comparison of the simulation results shows a considerable elastoplastic stress-strain response in the vicinity of pores whilst the surface of the gauge-length of the specimen remains in the elastic region of the material. Moreover, the distribution of the pore sizes seems more influential to the stress-strain field during the loading than their radial position in the gauge-length.

In this work, the effects of fairly influential factors on performance of vacuum system, such as constant pressure and outgassing effect were simulated to propose the optimum design factors. Outgassing effects of selected vacuum materials on the vacuum characteristics were simulated by the $VacSim^{Multi}$ simulation tool. This investigation examined the feasibility of reliably simulating the outgassing characteristics of common vacuum chamber materials (aluminum, copper, stainless steel, nickel plated steel, Viton A). The optimum design factors for vacuum systems were suggested based on the simulation results. And, the effects of throttle valve applications on vacuum characteristics were also simulated to obtain the optimum design model of variable conductance on high vacuum system. Simulated vacuum characteristics of the proposed modelling were agreed with the observed experimental behaviour of real systems. Pressure limit valve and normally on-off control valve were schematized as the modelling of throttle valve for the constant process-pressure. Simulation results were plotted as pump-down curve of chamber and variable conductance of throttle valve. Simulated behaviors showed the applications of throttle valve sustained the process-pressure constantly, stably, and reliably.

This paper is a research on perceived risk of social commerce which has influence on purchase intention. This study uses a 3-dimension concept of perceived risk and then, deals with influencing a purchase intention. In addition, to search other influential variable to purchase intention, this study adds a variable with expected moderating effect. This study proposes several hypothesis and processes an experiment to test and attest these hypothesis. This study attempts to analyze the effect that perceived risk in social commerce has on purchase intention. By the results of data analysis, all dimensions of perceived risk are found to have significant negative effects on purchase intention. In addition, this study proves moderating roles of valence of WOM Information on purchase intention. Additional managerial implications are also discussed.
