This study utilized the data from 2017, 2019 Korean National Health and Nutrition Survey to analyze the factors influencing depression and suicidal ideation among single-person households. For the analysis, demographic and economic variables as well as health status/behavior variables were considered. Activity restriction (OR: 4.753, p-value: <.0001) and smoking status (OR: 2.013, p-value: 0.044) were significantly associated with depression, and in terms of suicidal ideation, household income (OR: 3.526, p-value: 0.043), subjective health status (OR: 2.945, p-value: 0.007), activity restriction (OR: 2.263, p-value: 0.003) and smoking status (OR: 2.000, p-value: 0.023) showed significant association. In this regard, single-person households are likely to experience psychological angst, and further experience mental problems due to socio-economic and physical crisis. Therefore, it is necessary to establish a social network system in the community to detect those in need and provide appropriate interventions to prevent harmful outcomes.

In this study, a complex sample logistic regression analysis was performed to identify the factors affecting the activity restriction of 2,701 normal elderly and chronically ill elderly aged 65 and over using raw data from the 8th period of the National Health and Nutrition Examination Survey. It was found that the elderly with chronic disease felt more restricted in their activities than the normal elderly. Activity limiting factors in stroke and hypertension patients are subjective health status, economic level, stress perception, and moderate-intensity work and leisure. The factors limiting activity in patients with heart disease were subjective health status and economic level, and factors limiting activity in patients with joint disease were subjective health status and high-intensity work and leisure. Activity limiting factors for lung disease patients are education level, high intensity work and leisure, and endocrine system activity limiting factors include subjective health status, stress perception, high intensity work and leisure, and activity limiting factors for cancer patients. is subjective health status, stress perception, moderate-intensity work and high-intensity leisure. Rehabilitation programs and policy support are needed for the continuous participation of the elderly with chronic diseases.

The purpose of this study was to investigate the effect of dietary restriction(DG), aerobic exercise(EG), dietary restriction with aerobic exercise(DEG) on weight, improvement of obesity, blood lipid profiles and metabolic risk factors of obese female college students. Experiments was conducted 5 times a week for 8 weeks. DG spent 300kcal/day, and EG used 300kcal/day to run, DEG each consumed 150kcal/day limits. As s result, in case of body composition, weight(p<.011) and BMI(p<.008) were decreased in DG group, and weight(p<.044, p<.017), body fat(p<.047, p<.018), BMI(p<.03, p<.008), body fat%(p<.036, p<.015) and WHR(p<.049, p<.027) were decreased in EG and DEG groups. In case of blood lipid profiles's change, there are some differences on TC(p<.006), TG(p<.047) according to the time. In DG:HDL-C(p<.028), in EG:TG(p<.038), in DEG:TC(p<.014), LDL-C(p<.007) have decreased. In case of metabolic risk factor's change, there are some differences on FBG(p<.001), insulin(p<.004), HOMA-IR(p<.001), leptin(p<.000), adiponectin(p<.038), resistin(p<.010) according to time. In DG:HOMA-IR(p<.035) and leptin(p<.007), EG:FBG(p<.043) and leptin(p<.003), DEG:FBG(p<.014), insulin(p<.005), HOMA-IR(p<.005), leptin(p<.016), and resistin(p<.040) have decreased. In conclusion, combined treatment of eating restriction with aerobic exercise was the most effective way to improvement of weight, blood lipid profiles and metabolic risk factors in obese female college students rather than respectively alone treatment.

This study was performed to investigate the relationships between obese index and major risk factors of cardiovascular disease in CVD patients. Anthropometry, food intake patterns, blood pressure, serum lipids and hematological values were analyzed in 550 patients from June, 1991 to August, 1992. The results are as follows: Total food intakes, especially total vegetable food and alcohol intakes were significantly related with obese index, so that the heavier patients tended to consume more carbohydrate and less fat. The blood pressure were observed to have positive correlation with obese index in man but not in women. However, both in men and women, blood levels of TG, TC, and VLDL tended to be related to obese index positively, while HDL and HDL-C were shown to be oppositive. So, it seems that as the degree of obesity is higher the blood pressure and blood lipids patterns worse. Therefore, these results suggest that obesity is one of the major risk factors of CVD, and for prevention & treatment of the disease, controlling body weight by nutritionally adequate diet along with alcohol restriction is necessary.

Lately Construction industry tends to prefer remodeling of existing building rather then new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. Specially in case of Apartment houses, since vagueness on ownership and management authority on common part exists. So in this study we are to present the procedure of analyzing apartment house remodeling method through user request by approaching to several considerable factors in user request side.

The generator for gas turbine power generation consists of the rotor which generates magnetic field, the winding coil which is the path for the field current and the wedge and retaining ring which prevents the radial movement of the coil. Relatively severe deformation was observed at the coil end section during the inspection of the generator for peaking-load operation, and the thermal-electricity and the centrifugal force were evaluated by the simple modeling of the windings to find the cause. But the simulation stress was not sufficient to induce the coil plastic deformation. The analysis result seems to be applicable to the base-load generators which runs continuously without shut down up to a year, but there had been more deformation than simulated for the generator which is started up and shut down frequently. The cause of the coil deformation was the restriction of the expansion and shrinkage. The restriction occurs when the winding coil shrinks, and the stress overwhelms the yield stress and cause the plastic deformation. The deformation is accumulated during the start-ups and shut-downs and the thermal growth occurs. The factors which induce the coil restriction during the expansion and shrinkage should be reduced to prevent the unallowable deformation. The resolutions are cutting off the field current earlier during the generator shut-down, modifying the coil end section to remove the stress concentration and making the insulation plate inserted between the coil end section and the retaining ring have the constant thickness.

This study aimed to investigate the association between asthma and emotions, such as depression, stress, and health awareness. We observed the effects of blood indices on asthma in Korean adults. Data from 5852 adults were taken from the 2017 Seventh Korea National Health and Nutrition Examination Survey and analyzed using a multivariate logistic regression model. The probability of asthma occurrence in over 65 years old was higher than in 19-44 years old (OR = 1.48), and asthma occurrence was high in subjects with low educational (OR = 1.89) and income (OR = 2.07) levels. With regard to marital status, singleness and divorce and dye were found to have increased the probability of asthma occurrence by 1.62- and 2.30-folds, respectively. The restriction of activities was another factor that increased with asthma occurrence (OR = 2.39). In terms of emotions, general health awareness was significantly 3.45 times increased the probability of asthma occurrence at their health bad awareness. Furthermore, depression (OR = 1.782) was shown to have increased asthma occurrence. The blood index of C-CRP 1.12 times increased the probability of asthma occurrence. The factors that influenced asthma occurrence were age, education, income, marital status, the restriction of activities, general health awareness, depression, and C-CRP. Emotional factors and blood indices are potential risk factors for the development of asthma in Korean adults. By understanding the increased risks of asthma occurrence with general characteristics and emotional factors and blood indices, the management and prevention of asthma should include the management of emotional factors.

The classification of risk factors and the identification of risk acceptance criteria are core works to assess risk levels with high enough confidential level in the field of marine traffic environment. In the previous study work, the twenty kinds of risk factors and its assessment criteria for the domestic marine traffic environment were proposed. In this paper, with these previous studying results, the relative importance of the risk factors were analyzed by questionnaire survey of marine traffic experts using the analytic hierarchy process. The analysis results showed that the relative importance of the visibility restriction is the highest among the twenty kinds of risk factors, and the relative importance of the traffic condition is the highest among the five kinds of risk categories. As results from analysis, it is expected that the approaching method on the relative importance is to be one of basic techniques for the development of risk assessment models in the domestic marine traffic environment.

Environment Conversion Factors, which are stipulated in System Reliability Toolkit, have a lot of advantages once applied in a reliability data handbook such as NPRD-95, during the process of reliability prediction. However, the factors have a restriction in their applications because they don't deal with a few environments, e.g., Missile Launch (ML). In this study, environment factors of various components from MIL-HDBK-217F were analyzed to address this problem. Statistical computations showed that converting from Airborne Rotary Wing (ARW) to Missile Launch (ML) was the most coherent by comparing coefficient of determination. In addition, conversion factors from System Reliability Toolkit and those from the statistical calculations were evaluated in terms of their similarities.

Mothers play a major role in children's consumer socialization but little is known about differences in mother's consumer socialization tendencies and the antecedents causing the differences. This study addresses two research questions: First, what are the underlying dimensions of mother's consumer socialization? Second, what are the antecedent variables causing differences in mother's consumer socialization tendencies; can parental style, consumption-related attitudes (attitude toward marketplace and ads., attitude toward consumerism and consumption-oriented attitude) be used as a conceptual basis for hypothesizing these differences? The findings of this research were as follows: 1. Factor analysis suggested five underlying dimensions of mother's consumer socialization of children; Mother-child communication about consumption, Mediation of media, Reaction to purchase requests, Restriction of allowances and Restriction of consumption. 2. The differences in the mother's consumer socialization tendencies among different parental groups matched the differences in child-rearing behaviour suggested by Developmental Psychology and this provided support for expected relationships between general-consumer socialization tendencies, as measured by mothers' behaviour. 3. Differences were found on all factors according to mothers consumption-related attitude. This provided support for the expectation that mothers' consumption related attitudes are important antecedent variables causing differences in consumer socialization tendencies. Some implications and directions for future research were discussed.
