  • The purpose of this study was; 1) to describe consumer preferences for wood~framed housing; 2) to determine factors which affect the preferences for housing environments in wood-framed housing by demographic, current housing, and wood-framed housing-related characteristics; and 3) to identify differences in preferred wood-framed housing related characteristics by demographic and current housing characteristics. From the visitors to a model wood-framed house in Seoul, Korea, 296 persons willing to live in a wood-framed house were selected as the sample for the study. Data were collected using a self-administered survey and analyzed by frequency distribution, factor analysis, chi-square test, t-test, and one-way analysis of variance procedures. The results of the study Indicated that among seven factors based on 32 housing characteristics, Factor 2 - "floor plan and Interior environment" was the major variable which showed significant difference by selected demographic characteristics. Regarding the differences in wood-framed housing related characteristics by demographic characteristics, age, gender, education, and family life cycle showed group differences. Also, housing type was the major current housing characteristic to provide significant group difference in preferred wood-framed housing characteristics.

  • Purpose: This study investigated the effect of electroacupuncture stimulation on changes in blood biochemistry in spinal cord injury (SCI) rats whose cords were damaged by 6-hydroxydopamine (6-OHDA). Methods: Twenty-one Sprague-Dawley adult male rats were assigned to one of three groups: normal (n=7), control (n=7) and experimental group (n=7). The experimental group received electroacupuncture (Es-160, ITO, Japan) for 15 minutes in the form of low frequency (2 Hz) stimulation to the zusanli point. After treatment, we observed motor behavior recovery using the inclined plane test. We also measured serum and CNS concentrations and activities of enzymes including creatine kinase (CK), alkaline phosphatase (ALP), and Immunoglobulin G (IgG). Statistical analysis was done using one-way analysis of variance (ANOVA). Results: Concentrations of CK, ALP and IgG were lower in the experimental group than in the control group. Functional recovery was evaluated by the maximal angle of the inclined board on which rats could maintain their initial position. This allowed us to monitor progressive locomotor recovery. The maximal angles of the inclined plane test were higher in the experimental group than in the control group (p<0.05). Conclusion: The results of this study showed that electroacupuncture to the zusanli point has a therapeutic effect on functional recovery after SCI.

  • Risks, uncertainties, and associated cost overruns are critical problems for construction projects. Cost contingency is an important funding source for these unforeseen events and is included in the base estimate to help perform financially successful projects. In order to predict more accurate contingency, many empirical models using regression analysis and artificial neural network method have been proposed and showed its viability to minimize prediction errors. However, categorical factors on contingency cannot have been treated and thus considered in these empirical models since those models are able to treat only numerical factors. This paper identified potential factors on contingency in transportation construction projects and evaluated categorical factors using the one-way ANOVA statistical method. Among factors including project work type, delivery method type, contract agreement type, bid award type, letting type, and geographical location, two factors of project work type and contract agreement type were found to be statistically important on allocating cost contingency.

  • Purpose: The purpose of this study was to compare health promoting behavior between working and non-working mothers with infants and toddlers, and to investigate factors affecting the mothers'health promoting behavior. Methods: This descriptive study was conducted through conveniently sampled 403 women who visited the child health clinics at two public health centers. The questionnaire included the Health Promoting Life Style Profile (HPLP) and a visual analogue scale for subjective health status. ANCOVA, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted using SPSS ver. 21. Results: Working mothers' average HPLP score ($2.30{\pm}0.37$) was higher than non-working mother's ($2.15{\pm}0.37$). The score of the physical activity subscale was lowest among the subscales and there was a difference between the two groups. Subjective mental health status was the only predictor of working mothers'health promoting behavior, and it explained 23.2% of variance in health promoting behavior. Subjective mental health status, education, and age were the predictors of non-working mothers' health promoting behavior and they explained 27.2% of variance in health promoting behavior. Conclusion: According to the findings, both working and non-working mothers' health promoting behaviors were low. To promote mothers' health, it is necessary to develop diverse community health promotion programs to support mothers.

  • Prostate cancer is a high-risk with a high incidence and is a disease that occurs only in men. Accurate diagnosis of cancer is necessary as the incidence of cancer patients is increasing. Prostate cancer is also a disease that is difficult to predict progress, so it is necessary to predict in advance through prognosis. Therefore, in this paper, grade classification is attempted based on texture feature extraction. There are two main methods of classification: Uses One-way Analysis of Variance (ANOVA) to determine whether texture features are significant values, compares them with all texture features and then uses only one classification i.e. Benign versus. The second method consisted of more detailed classifications without using ANOVA for better analysis between different grades. Results of both these methods are compared and analyzed through the machine learning models such as Support Vector Machine and K-Nearest Neighbor. The accuracy of Benign versus Grade 4&5 using the second method with the best results was 90.0 percentage.

  • Purpose: The reproductive health of women in early adulthood can affect pregnancy, childbirth, and menopause in later life. Menstrual symptoms not only affect daily life, but are also a reflection of a woman's reproductive health. This study was conducted to explore the factors affecting menstrual symptoms among university students. Methods: The general characteristics, life style, menstrual characteristics, stress, and menstrual symptom of 177 female students were assessed through an online survey at one university. An independent sample t-test, one-way variance analysis, correlation analysis, and multiple regression analysis were performed using the SPSS 22.0 program. Results: The menstrual symptom score was 91.68±32.11 points, and the score of 'mood change' was the highest. Stress (��=.38, p<.001), amount of menstruation (��=.20, p=.001), menarche age (��=-.18, p=.003), health problems (��=.16, p=.010), and age (��=.15, p=.016) were found to have a significant effect on menstrual symptom, and the explanatory power of the regression model was 40%. Conclusion: This study investigated the degree and influencing factors of menstrual symptom using the Korean Menstrual Symptom Scale (KMSS) developed for Korean university students. Among the factors influencing menstrual symptom, stress appeared to play a significant role. Stress management, observation of menstrual characteristics, and general health care are necessary to maintain a woman's reproductive health.
