The purpose of this study was to determine the relationship between gymnasium selection and training adherence of security martial arts trainees. To this aim, this study selected 8 gymnasiums in Gyounggi and Incheon province and sampled 220 people above the fourth grade in elementary school. Out of these, 14 cases were dropped due to insufficient answers or incomplete answers, and 206 qualified cases were finally adopted for this study. Data were analyzed using exploratory factor analysis, reliability analysis and frequency analysis, MANOVA, correlation analysis and multiple regression analysis with SPSS 18.0. The results of this study were as follows. First, there were significant differences in gymnasium selection factors(instructor background, training program, public relations) depending upon the trainee's sex. Second, there were significant differences in gymnasium selection factors(training program, main others, public relations) depending upon the trainee's school grade. Third, there were no significant differences in training adherence factors depending upon the trainee's sex and school grade. Fourth, there were positive correlations between instructor background, training program and public relations-factors among gymnasium selection and management program, external and social relations-factors among training adherence. Fifth, the partial sub-factors of gymnasium selection have influenced training adherence. Consequently, security martial arts managers and instructors need to establish marketing strategies suitable for sex and school grade to recruit new security martial arts trainees. It may be considered that security martial arts instructors should construct the differentiated management system for trainees and the specialized training program for lasting training of new or existing security martial arts trainees.

The aim of this study was to investigate whether fourier transform infrared (FT-IR) spectroscopy can be applied to simultaneous determination of fatty acids contents in different soybean cultivars. Total 153 lines of soybean (Glycine max Merrill) were examined by FT-IR spectroscopy. Quantification of fatty acids from the soybean lines was confirmed by quantitative gas chromatography (GC) analysis. The quantitative spectral variation among different soybean lines was observed in the amide bond region ($1,700{\sim}1,500cm^{-1}$), phosphodiester groups ($1,500{\sim}1,300cm^{-1}$) and sugar region ($1,200{\sim}1,000cm^{-1}$) of FT-IR spectra. The quantitative prediction modeling of 5 individual fatty acids contents (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid) from soybean lines were established using partial least square regression algorithm from FT-IR spectra. In cross validation, there were high correlations ($R^2{\geq}0.97$) between predicted content of 5 individual fatty acids by PLS regression modeling from FT-IR spectra and measured content by GC. In external validation, palmitic acid ($R^2=0.8002$), oleic acid ($R^2=0.8909$) and linoleic acid ($R^2=0.815$) were predicted with good accuracy, while prediction for stearic acid ($R^2=0.4598$), linolenic acid ($R^2=0.6868$) had relatively lower accuracy. These results clearly show that FT-IR spectra combined with multivariate analysis can be used to accurately predict fatty acids contents in soybean lines. Therefore, we suggest that the PLS prediction system for fatty acid contents using FT-IR analysis could be applied as a rapid and high throughput screening tool for the breeding for modified Fatty acid composition in soybean and contribute to accelerating the conventional breeding.

This study was carried out to explore the accuracy of Near Infrared Reflectance Spectroscopy (NIRS) fer the prediction of digestibility and energy value of corn silages. The spectral data were regressed against a range of digestibility and energy parameters using modified partial least squares(MPLS) multivariate analysis in conjunction with first and second order derivatization, with scatter correction procedure(SNV-Detrend) to reduce the effect of extraneous noise. Calibration models for NIRS measurements gave multivariate correlation coefficients of determination$(R^2)$ and standard errors of cross validation of 0.92(SECV 1.73), 0.91(SECV 1.13) and 0.93(SECV 1.74) for in vitro dry matter digestibility(IVDMD), in vitro true digestibility(IVTD), and cellulase dry matter digestibility(CDMD), respectively. The standard error of prediction(SEP) and the multiple correlation coefficient of validation$(R^2v)$ on the validation set(n=39) was used in comparing the prediction accuracy. The SEP value was 0.30(TDN), 0.01(NEL), and 0.01(ME). The relative ability of NIRS to predict digestibility and energy value was very good for CDMD, total digestible nutrients(TDN), net energy fer lactation(NEL) and metabolizable energy(ME). This paper shows the potential of NIRS to predict the digestibility and energy value of con silage as a routine method in feeding programmes and for giving advice to farmers.

The aim of this study was to determine the mediating effects in the relationships among nursing organizational culture, workplace bullying, and job stress of nurses. For the descriptive correlational study design, data were collected using a structured questionnaire from nurses at university hospitals (N=130). Statistical analysis was performed on the collected data using SPSS 22.0 statistics program. The mean scores of nurses for nursing organizational culture, workplace bullying, and job stress were 2.99±0.74, 1.85±0.65, and 2.50±0.35, respectively. Nursing organizational culture of nurses had a negative correlation with both workplace bullying (r=-0.45, p=0.001) and job stress (r=-0.61, p=0.001), whereas workplace bullying showed a positive correlation with job stress (r=0.42, p=0.001). Sobel test was conducted to verify the mediating effects, and nursing organizational culture was statistically significant as a partial mediating effect of 0.13 (sobel'z=-2.287, p<0.05) on the effect of workplace bullying of nurses on job stress. These results indicate that nursing organizational cultures need to be established to reduce workplace bullying. It is important to create a nursing work environment that can reduce job stress, a better understanding of the nursing organization cultures related to nursing tasks is crucial, and it is necessary to develop an institutional education strategy for prevention education in hospital organizations.

Understanding the relation between basic science and applied science is important for students in understanding the importance of learning science, the relationship between scientific knowledge and human life, and for enhancing their science motivation. In this study, we evaluated the statistical validity of this hypothetical model and explored the effect of gender and students' preferred courses (e.g., humanities, science, and art) on four dependent variables. We also evaluated the differences of students' understanding across scientific domains and students' understanding concerning basic and applied scientific knowledge. Three hundred and twenty five 10th grade students participated in this survey research. Statistically, we employed bivariate correlation, partial correlation, path analysis, two-way ANOVA, and repeated measures ANOVA. Our findings illustrated that our hypothetical model was statistically valid. In addition, the significant interaction effects of gender and students' preferred courses on each dependent variable were shown. Students have different levels of understanding of the convergence of basic and applied science, the relation between scientific knowledge and human life, and the importance of learning science across scientific domains (e.g., physics, chemistry, earth science and biology).

Objectives : This study was done to evaluate the effect of stopping drinking, using alcoholic liver disease questionnaire, Diagnosis System of Oriental Medicine (DSOM) and Health Related Quality of Life (HRQOL). Methods : 49 men who satisfied the requirement participated in this trial. They stopped drinking for 6 weeks. They were analyzed using DSOM, alcoholic liver disease questionnaire and SF-36. The data were classified by age (<47,$\geq$48) and alcoholic intake per day (<100g,$\geq$100g). For HRQOL, the SF-36v2 Health Survey was used and Quality Metric Health Outcomes Scoring Software 2.0 (QualityMetric, Lincoln, RI, USA) was applied for the analysis. Results : The alcoholic liver disease questionnaire had a partial correlation with DSOM. Generally stopping drinking decreased Heat (熱). Especially in the group drinking over 100g per day, the correlation was high. In the group over 48 years old, spleen (脾) was improved comparatively. In the group with low HRQOL (PCS<31.43, MCS<23.33) deficiency (虛) was improved. Conclusions : We found that stopping drinking can improve pathogenic factors of alcoholic liver disease and the alcoholic liver disease questionnaire be a useful diagnostic method on alcoholic liver disease by comparison with DSOM.

The intent of this study was to focus attention on the relationship between curtain fabrics and consumer perceptions towards curtains and draperies. This study consisted of the laboratory test for thermal transmittance of selected fabrics and the exploratory survey for consumer perceptions towards curtains and draperies. The objectives of the laboratory test were to measure fabric's thermal transmittance, thickness, and count which affect to the effect in heat controlling. Selected 23 fabrics were tested at Korean Yarn and Fabrics Testing Inspection Institute. The objectives of the exploratory survey were to determine sociodemographic factors; the stage of family life cycle, the economics status, and homemaker's level of education, and physical factors; the type of houses, the direction of windows, and the type of windows, affect consumer perceptions toward curtains and draperies. Questionaires were administered to 489 homemakers selected by a stratified propotional sampling plan, in Seoul in October, 1981. Data from responses were analyzed by T-test(Analysis of Varience) and Partial Correlation. The major findings are as follows; 1. The results of the laboratory test 1) The fabrics used for draperies had higher effect in heat controlling than the fabrics used for glass curtains. 2) It did not show much differences among the fibers in heat controlling. The thicker fibers, however, had the higher effect in heat controlling among same fibers. 3) The fabrics which had high level of effect I heat controlling were corduroy, flax, rayon, nylon, acetate, thick polyester, and thick polyacrylic. The fabrics which had midium level of affect in heat controlling were velveteen, velvet, and thin polyester. The fabrics which had low level of effect in heat controlling were cotton, silk, and thin polyarcylic. 4) The draperies with lining showed 2∼5 times more effective in heat controlling than the draperies without lining. 2. The results of the exploratory survey Consumer perceptions towards curtains and draperies consisted of functional, financial, and aesthetic perception. 1) Factor affecting functional perception towards curtains and draperies was the stage of family life cycle. Families in the contracting stage considered function of curtains and draperies significantly better than those in others stages. 2) Factors affecting financial perception towards curtains and draperies were the economic status, homemaker's level of education, the direction of windows, and the type of windows. However the correlation between the factors and financial perception was too low to explain the significance of tendency. 3) There was not any factors affecting aesthetic perception towards curtains and draperies.
