Traditional quality control for manufacturing or service sector is not suitable for the quality control of a project as the project is one-time task constrained by time, cost, and quality. To meet the internal and external customers' requirements, quality costs approach to the project will be effective. Hence, we propose PONC (price of nonconformance) estimation procedure and a mathematical model, which are focused on activity-based prevention in the execution step and warranty step of EPLC (extended project life cycle). This procedure and model will help project manager develop preventive action plan for project quality costs minimization from nonconformance risk activities and PONC estimates information.

Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Results showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivor's health and quality of life.

The purpose of this study is to reveal the similarity and difference by comparing the quality of life between senior citizen group and disabled people group. For this purpose, I surveyed the questionnaire composed of sociological variable of population, social support, society activity participation, activity of daily living, self-efficacy, and quality of life to 113 senior citizens and 107 disabled people and analyzed the actual proof relationship of cause and effect in between variables. I executed the analysis of structural equation model by using SPSS 14.0 and AMOS 7.0 for the analysis of data. As the result of the study, firstly, the variables highly co-related with the quality of life to both senior citizen group and disabled people group were self-efficacy and society activity participation, and the variables highly co-related with self-efficacy were the quality of life and society activity participation. Secondly, the variables which show the meaningful difference between senior citizen group and disabled people group were society activity participation and activity of daily living. Thirdly, in the senior citizen group, social support, society activity participation, and activity of daily living have meaningful effect on self-efficacy, and all variables have meaningful effect on the quality of life. However, in the disabled people group, social support did not have meaningful effect on self-efficacy, and the social support and self-efficacy did not have meaningful effect on the quality of life. Based upon these study results I discussed the meaning and implications of the study, and suggested the successive study tasks.

Purpose - We investigate whether a firm's engagement in socially responsible activity affects the quality of financial reporting within the retail industry of Korean market. Recent studies argue that more socially responsible firms tend to show a better quality of financial reporting. Research design, data, and methodology - We use a variety of proxy variables related to the use of discretionary accruals and real activity manipulation to measure the quality of financial reporting. The total of environmental, social and governance score is used to represent the degree of socially responsible activity in the retail industry. We use regression models to examine whether more socially responsible firms show a higher quality of financial reporting. The sample of publicly traded Korea retail firms is analyzed from 2011 to 2016. Results - Our analysis finds supporting evidence for limited earning management via the use of discretionary accruals. We find, however, no significant relationship between the degree of social responsibility and the quality of financial reporting within chaebol affiliates unlike non-chaebol affiliates. Conclusions - Our results weakly support a better quality of financial reporting for more socially responsible firms. The results highlight the importance of firm characteristics in deciding the effect of socially responsible activity on corporate policies.

The purpose of this study was to assess gender differences in the quantity and quality of leisure time. It uses time diary for a nationally representative sample of Koreans(10 years old over) collected in 2004 by KNSO. This time use surveys provide information about a primary activity and a secondary activity (that is simultaneous activity accompanying the primary activity). The results was that married women experience less of leisure time and more contaminated leisure time by a secondary activity(especially household labor) than married men. This research presents that men and women have different quantity and quality of leisure time, and gender discrepancies persist in the experience of leisure time.

This study was conducted to analyze the relationship between sleep quality, stress response, physical activity and sleep hygiene in shift work nurses and identify factors influencing sleep quality. The participants were 168 shift nurses from university hospitals and general hospitals located in C city, Gyeongnam. Data were collected from March 25 to 31, 2016. The study instrument use to the Pittsburgh Sleep Quality Index, Stress Response Inventory, Korean version of the International Physical Activity Questionnaire Short Form and Sleep Hygiene Scale. Date were analyzed by frequency, t-test, ANOVA, Pearson's correlation and hierarchical multiple regression using SPSS/win18.0. The sleep quality index was 7.35 (range 0-21), stress response was 2.20 (range 1-5), physical activity was 3986MET-min/week, and sleep hygiene was 2.73 (range 1-6 points). There were significant differences in sleep quality according to shift work experience, health status and circadian rhythm type. Factors influencing sleep quality included shift work experience, sleep hygiene, stress response and physical activity, which together explained 40% of the total variance of sleep quality. Therefore, it is recommended that sleep hygiene education be implemented as a strategy to reduce stress response, and that shift work nurses engage in a moderate level of physical activity to improve their sleep quality.

Purpose: The purpose of this study was to identify the effect of the physical activity promotion program on physical function and quality of life in the elderly. Method: The research was designed with one single pre-post group. The study group of 295 elderlies were selected through the convenience sampling form in a senior citizen's center in Ulsan city. The subjects received the physical activity promotion program for 60 min three times a week for 3 months. To evaluation the effects of the physical activity promotion program, body mass index (BMI), physiological index, physical function (muscle endurance, agility, balance) and quality of life were measured at before and after the program. The data was analyzed through SPSS 10.0 program for descriptive statistics and paired t-test. Result: After performing the physical action promotion program for 3 months, the results were follows. 1) There were significantly increased in BMI (t=4.36, p=.000). 2) There were significantly decreased in diastolic pressure (t=.68, p=.009). 3) There were significantly improved in muscle endurance (t=6.50, p=.000), agility (t=4.74, p=.000) and Rt. leg balance (t=4.15, p=.000). 4) There were significantly improved in quality of life (t=7.28, p=.000). Conclusion: These findings showed that the physical activity promotion program was effective in improving physical function and quality of life in the elderly. Therefore, the physical activity promotion program could be applied as an effective nursing intervention program for the elderly to promote their health.

The purpose of this study was to investigate the convergence factors affecting of physical activity level on hemodialysis patients' depression, health-related quality of life and sleep disorders. The participants were 193 hemodialysis patients undergoing hemodialysis in five hospitals in two cities. Data were analyzed by technical statistics, correlation and hierarchical regression. The results showed that depression and physical activity were negatively correlated (r = -.259, p <.01), and physical and mental health related quality of life and physical activity correlated positively (R = .273, p <.01, r = .186, p <.01), respectively. Hierarchical regression analysis showed that the higher the quality of life related to physical health, the higher the level of physical activity of hemodialysis patients (${\beta}=.22$, p <.01). Therefore, it is required to develop an intervention program to improve health-related quality of life by improving the physical activity of hemodialysis patients.

Purpose of this study is to empirically consider relation between QM activity factor and management result. For this, following 6 major variables of QM activity were established as independent variable; CEO's leadership, communication, process control, standardization, full participation and education/training while satisfaction of members and improvement of quality were established as dependent variable. And, a model was set up and hypothesis verification was conducted on the basis of data collected through questionnaires. The results are summarized as follows; First, QM factors which influenced satisfaction of members in management result were CEO's leadership, communication, process control, full participation and education/training but 'standardization' factor was not statistically significant. Second, QM factors which influenced improvement of quality in management result were CEO's leadership, communication, standardization, full participation and education/training but 'process control' factor was not statistically significant. Third, among main factors of QM activity, the factor which preferentially influenced satisfaction of members was 'full participation' factor while the factor which preferentially influenced improvement of quality was 'standardization' factor. According to such results, it is required to seek a statistical method regarding QM activity with focus on the factor of 'full participation' and 'standardization' among other things for the purpose of satisfaction of members as well as improvement of quality. It is believed that implication of this study can be useful information to realize management result considering main factors of QM activity and that it also can be basic reference data to seek a statistical method for satisfaction of members and improvement of quality by grasping core factors having influence over QM activity.

This study intends to provide basic data to confirm the convergence effects of economic activity on the quality of life and oral health of middle-aged Korean women. Data from the 2019 National Health and Nutrition Examination Survey were used, and complex sample logistic regression analysis and linear regression analysis were performed to confirm the effect of economic activity on health-related quality of life (Korean Health-related Quality of Life Instrument with 8 Items; HINT-8) and oral health-related factors. As a result, in the case of controlling for demographic characteristics and economic activity, there was a significant effect in 4 items (energy, work, memory, sleep) out of HINT-8. When the oral health status was adjusted, there was a significant effect only in 2 items (working and memory) of HINT-8 (p<.05). Therefore, although economic activity of middle-aged Korean women has a positive effect on quality of life, it is considered to be valuable in that oral health status can reduce the influencing factors.
