Objectives : The purpose of this study was to investigate the characteristics of psychosocial factors related to functional dyspepsia(FD) and their effects on quality of life(QOL) in firefighters. Methods : This study examined data collected from 1,217 firefighters. We measured psychological symptoms by Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) and World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF). Chi-square test, independent t-test, Pearson's correlation test, logistic regression analysis, and hierarchical regression analysis were used as statistical analysis methods. Results : For the group with FD, the male participants showed significantly higher frequency(p=0.006) compared to the female participants. The group with FD had higher scores for depressive symptoms(p<.001), anxiety (p<.001), and occupational stress(p<.001), and did lower scores for self-esteem(p=.008), quality of life(p<.001) than those without FD. The FD risk was higher in the following KOSS subcategories: job demand(OR 1.94, 95% CI : 1.29-2.93), lack of reward(OR 2.47, 95% CI : 1.61-3.81), and occupational climate(OR 1.51, 95% CI : 1.01-2.24). In the hierarchical regression analysis, QOL was best predicted by depressive symptoms, self-esteem, and occupational stress. Three predictive variables above accounts for 42.0% variance explained of total variance. Conclusions : The psychosocial factors showed significant effects on FD, and predictive variables for QOL were identified based on regression analysis. The results suggest that the psychiatric approach should be accompanied with medical approach in future FD assessment.

Objectives : The Center for Epidemiologic Studies Depression scale-Revised is a recently revised scale which has been reported as a valid tool for the assessment of depressive symptoms. It encompasses cardinal symptoms of depression described in the Diagnostic and Statistical Manual of Mental disorders, fourth edition. In this study, we assessed the reliability, validity and psychometric properties of the Korean version of the CESD-R(K-CESD-R). Methods : Forty-eight patients diagnosed as major depressive disorder, dysthymia, depressive disorder NOS according to the DSM-IV criteria using Mini International Neuropsychiatric Interview and 48 healthy controls were enrolled in this study. They were assessed with K-CESD-R, K-MADRS, PHQ-9, KQIDS-SR, STAI to check cross-validation. Statistical analyses were performed using calculation of Cronbach's alpha, Pearson correlation coefficient, Principal Component Analysis, ROC curve and optimal cut-off value. Results : The Cronbach's alpha of K-CESD-R was 0.98. The total score of K-CESD-R revealed significantly high correlations with those of K-MADRS, PHQ-9, KQIDS-SR(r=0.910, 0.966 and 0.920, p<0.001, respectively). Factor analysis showed two factors account for 76.29% of total variance. We suggested the optimal cut-off value of K-CESD-R as 13 according to analysis of the ROC curve which value sensitivity and specificity both equally. Conclusions : These Results showed that the K-CESD-R could be a reliable and valid scale to assess depressive symptoms. The K-CESD-R is expected as a useful and effective tool for screening and measuring depressive symptoms not only in outpatient clinic but also epidemiologic studies.

Objectives:To determine the influence of parental behaviors on the onset and severity of eating disorders, this study compared aspects of perceived parental styles, according to eating disorder subtypes and age at onset in Korean women with eating disorders. Methods:One hundred and sixty-seven patients with eating disorders[Anorexia Nervosa (AN), N=49; Bulimia Nervosa(BN), N=118] were recruited for this study. Perceived parent behaviors were assessed with Parental Behavior Inventory(PBI) self-rating scale. The study subjects also completed the Eating Disorder Inventory -2 (EDI-2) to assess the severity of eating disorder symptoms. Results:In anorexia nervosa, early onset group(<16 years) reported low paternal affection and high paternal rational expression, low maternal interference than group with age at onset over 16 years. The severity of eating disorder symptoms was negatively associated with mother affection and rational expression in two subtypes of eating disorder(AN and BN). On stepwise regression analysis, paternal affection and maternal over-protection were associated with age of onset only in AN group and maternal affection was associated with the severity of symptoms in both groups of eating disorder. Conclusions:Considering the role of family function and perceived parental styles could help improve the management of eating disorders. These results emphasize the importance of fathers' role in the eating disorder on the age of onset, a relatively unexplored area of eating disorder research. Also, we investigated the importance of mothers' affection on the severity of symptoms.

Objectives:Within the normal reproductive cycles of women, dramatic fluctuations of sexual hormones occur in the premenstrual and menopausal periods. In both periods, women are vulnerable to mood disturbances and show several somatic complaints. Based on these common clinical profiles and physiological changes, a relationship between vasomotor symptoms and the premenstrual syndrome has been suggested. However, attempts to establish such a link have yielded inconclusive results. The purpose of this study was to investigate the association between histories of premenstrual syndrome and menopausal vasomotor symptoms within different menopausal stages. Methods:This cross-sectional study recruited Korean women aged 45-64 years who were perimenopausal and postmenopausal from 16 branch offices of the Korean Association of Health Promotion. All subjects completed self-report questionnaires that asked about a history of premenstrual syndromes, vasomotor symptoms, and several other variables. Results:A total of 1054 participants(361 perimenopausal women and 693 postmenopausal women) completed the study. Severity of premenstrual symptoms significantly correlated with postmenopausal vasomotor symptoms, only in late perimenopausal(r=0.213, p=0.010) and early postmenopausal women(r=0.246, p<0.001). After adjusting for several factors related to vasomotor symptoms, a history of premenstrual syndrome was a significant predictor of moderate to very severe vasomotor symptoms in late perimenopausal(OR=5.197, p=0.005) and early postmenopausal women(OR=3.017, p=0.010). Conclusions:This study suggests that a history of premenstrual syndrome/premenstrual dysphoric disorder is differentially associated with vasomotor symptoms in the menopausal stage. Prospective studies with larger population are needed to confirm these findings

Objectives:The purpose of this study was to evaluate reliability and validity of the Korean version of the Postconcussional Syndrome Questionnaire(KPCSQ) which was originally developed in 1992 by Lees-Haley. Methods:Patients with traumatic brain injury were recruited from April 2009 to December 2011 from the Korean University Ansan Hospital. We selected patients that met the ICD-10 diagnostic criteria of postconcussional syndrome and organic mental disorder including organic mood disorder, organic emotionally labile disorder, organic anxiety disorder and organic personality disorder. The KPCSQ, Trait and State Anxiety Inventory(STAI-I, II), and Center for Epidemiologic Studies Depression Scale(CESD) were administered to all subjects. Factor analysis of the items were performed and test-retest correlation were evaluated. Internal consistency of the KPCSQ and its subscales was assessed with Cronbach's alpha. External validity of the KPCSQ were examined by correlation coefficient with the STAI-I, II, and CESD. Results:The Cronbach's alpha coefficient of the total PCSQ was 0.956. The test-retest reliability coefficient was 0.845. The PCSQ showed significant correlation with STAI-I, II and CESD. The factor analysis of the PCSQ yielded 4 factors model. Factor 1 represented 'affective and cognitive symptoms', factor 2 represented 'somatic symptoms', factor 3 represented 'infrequent symptoms' and factor 4 represented 'exaggeration or inattentive response'. There was no significant difference between the PCS group and the organic mental disorder group in the score on each measure. The scores on KPCSQ and its subscales in the subjects that had scored 5 or more in 'exaggeration or inattentive response' are significantly higher than those in the subjects had scored 4 in 'exaggeration or inattentive response'. Conclusions:This study suggests that the Korean version of PCSQ is a valid and reliable tool for assessing psychiatric symptomatology of patients with traumatic brain injury. Further investigations with greater numbers of subjects are necessary to assess the clinical usefulness of the KPCSQ.

The present study was conducted to investigate the effects on growth performance, nutrient digestibility, and gut health of broiler chickens when a dietary supplementation of multienzymes was added to diets, containing different energy levels. A total of 480 broiler chickens of similar body weight (Ross 308, 1-day-old) were randomly subjected to four treatments. The dietary treatments included a corn-soybean meal-based diet supplemented with: multienzyme (amylase+protease+ mannanase+xylanase+phytase), 0.05% enzyme, and different energy levels (3010 and 3060 kcal/kg). The experimental diets were fed to the chicks in a mash form for 35 days in two phases (1-21 d, phase I; and 22-35 d, phase II). During the overall period, chicks fed with diets supplemented with multienzymes had a better weight gain (p<0.05) and feed conversion ratio (FCR) than those fed with diets without enzymes. There was no difference in the growth rate and FCR among the chicks fed with diets supplemented with enzymes, even though the dietary energy levels were different. The apparent fecal and ileal digestibility of dry matter, gross, crude protein, calcium, and phosphorus were significantly enhanced (p<0.05). The population of cecal and ileal Lactobacillus spp. was significantly increased (p<0.05), and Clostridium spp. and coliforms were significantly decreased (p<0.05) in diets supplemented with enzymes. Villus height and villus height to crypt depth ratio in the small intestine was also significantly enhanced (p<0.05) in diets supplemented with enzymes. In conclusion, multienzyme supplementation had positive effects on the weight gain of broilers, FCR, digestibility of nutrients, and on the growth of intestinal microbiota.

The 10th constitution established in 1987 serves as the theoretical foundation of democracy in South Korea in the 21st century. Respect for human rights, resistance to injustice, and equality consciousness inherent in this constitution do not conflict with the content of Confucian philosophy. This means that the spirit of the constitution of South Korea in the 21st century was formed under the influence of the idea of democracy and Confucian philosophy. However, the 10th constitution attaches importance to the idea of the 'Basic free and democratic order', which was accepted in the Yushin constitution and inherited by the military forces. The Yushin constitution was affected by liberalism that prioritizes freedom over equality rather than supporting the compatibility between freedom and equality. Therefore, policies to expand the interests of the bourgeoisie rather than public welfare or the interests of the public have been implemented frequently. In particular, during the Lee Myeong-bak and Park Geun-hye regimes, many unequal phenomena were mass-produced. Confucian philosophy in the 21st century critically sees this unequal society. Confucian philosophy thinks that a sense of relative deprivation plays a role of alienating humans and emphasizes the importance of equal relationships. In addition, this constitution emphasizes the rule of law. However, the rule of law attaches importance to positive laws when the spirit of the constitution that contains natural law is applied to reality through systems. This rejects autonomous judgments and choices while inducing reliance on heteronomy. These heteronomous laws as such are accompanied by forcibleness. The positive laws as such can degrade humans into passive beings that indiscriminately adapt themselves to frames already set instead of active beings that think freely and creatively. Confucian philosophy regards and criticizes the rule of law as a system that makes humans into a means. Confucian philosophy regards humans as moral beings instead of tools. Confucian philosophy seeks to build a healthy society through morality accomplished through conscious realization of the principles of life. Confucian philosophy regards humans as originally free beings. Therefore, human beings are autonomous beings, not heteronomous beings. According to Confucian philosophy, humans beings that can realize the morality contained in their inner side by themselves to responsibly carry out their own judgments and choices. Therefore, Confucian philosophy, which considers human beings as beings to be trusted instead of beings to be distrusted, attaches importance to the realization of human decency through edification rather than by punishment through the law. This means that human values cannot be kept by the heteronomy termed positive laws but the identity of humans can be maintained by voluntary choices and judgments. As such, the comment of Confucian philosophy on the problems of liberal democracy and positive laws contained in the 10th constitution can be helpful in essentially solving the contradictions of modern South Korean society.

Kant's doctrine of virtue shows how an actor should behave morally in an individual situation with moral law defines the limits of human action. There is latitude for action in the course of formulating the maxims of action by an actor. And moral judgement, as Aristotle's Pronesis, is very important in the latitude for action. In the doctrine of virtue, Kant suggests two kinds of duty of virtue: one's own perfeciton as an obligatory end, and the happiness to others as an obligatory end-and raises the question of casuistics for each. However, this was the practice and training for the human moral life by application of the moral law. In particular, Kant saw that ethics does not give laws for action, but only give laws for the maxims of action, and further intended to realize the practice in a proper way of seeking truth through casuistical questions. Thus, Kant points out that the casuistic is related only to ethics in a fragmentary way and is added to ethics only as a comment on the system. According to Kant, virtue and judgment are inevitable to apply categorical imperative in the empirical and realistic world. In other words, virtue and judgment are necessary to enable people who are likely to act in accordance to inclination to live a moral life in accordance with the command of reason. Thus Kant saw that in order to take wide duty into narrow ones, human beings must not only have to cultivate virtues as a strong power of will, but also to exercise judgment. In addition, the distinction between duty of law(narrow obligation) and duty of virtue(wide obligation) is dependent on whether there is a latitude for action in the application of both duties. So the role of virtue and training of judgement is very important in the latitude for action that occurs in the process of formalizing actor's maxims. In detail, as the duty is wider, so man's obligation to action is more imperfect, but the closer to narrow duty(Law) he brings the maxim of observing this duty(in his attitude of will), so much the more perfect is his virtuous action. Thus, it was an effort to show how Kant's best moral principles, that is categorical imperative could be applied to the real world at the time of criticism. Of course, even if it is difficult to assess Kant's efforts as successful, criticizing Kant's ethics as 'formal', 'abstract', or 'monologous' is not persuasive because of critics did not understand his ethics as a whole.

Lab scale experiments were conducted in order to assess the applicability of $CaCO_{3}$-alginate beads as neutralizer for the high cell density cultivation and prepare the direct vat inoculation cultures of isolated sourdough lactic acid bacteria. With increasing the amount of bead and decreasing the diameter of bead in acidic solution, the neutralizing effect of $CaCO_{3}$-alginate bead became higher. In batch process with $CaCO_{3}$-alginate beads, Lactobacillus amylovorus DU-21 isolated from sourdough showed the highest viable cell counts and optical density in MRS broth. The values of viable cell counts and optical density were 9.996 log CFU/mL and 3.97, respectively. Experiments on the conditions which increase viability during lyophilization were carried out and the following results were obtained; 15% glycerol revealed the high cryoprotective effect on the concentrated cultures during lyophilization among the two cryoprotective agents. Consequently, $CaCO_{3}$-alginate beads and 15% glycerol were found to be useful not only to cultivate Lactobacillus amylovorus DU-21 but also to preserve strain.

The purpose of this study is to seek ways of utilizing TLBMC by understanding business model of social ventures that are accompanied by social and environmental as well as economic missions. In order to achieve this, business models from economic, environmental and social perspectives will be analyzed, and we seek to enhance sustainability of social venture entrepreneurs. As the analysis tool, TLBMC(Triple Layered Business Model Canvas) expands upon the business model canvas that is widely utilized and recognizes economical terms. The TLBMC is proposed by Joyce, A., & Paquin, R. L.(2016) to help achieve a holistic view with horizontal and vertical associations. The study tries to overcome limitations of previous studies and observe a variety of economic, environmental, and social perspectives that social ventures should have with the TLBMC. As a result, it has the following implications; Firstly, creating separate social, environmental and economic business model canvas helps a business to have a holistic approach. Secondly, it was found that social venture characteristics of environmental and social perspectives were applied in practice. Lastly, we have established experience data on social venture business model. This study focuses on the opinions, the meanings and the subjective views of the participants. As a result, conclusions are drawn by the researchers ' assertions and has limitations as a research on case studies. However, this study will help people who are preparing or studying social ventures to have economic, environmental, and social perspectives. Also, redefinition of the direction and value of entrepreneurs operating social ventures, such as vision and mission, will help clarify the roles and responsibility of organizations. As a fundamental step for future empirical studies, this study could be the base for social venture business model studies.
