Purpose: This study was conducted to investigate the prognostic factors of postpsychotic depressive symptoms in patients with schizophrenia. Materials and Methods: Eighty patients were selected based on the diagnostic criteria from the DSM-IV, PANSS and ESRS. For all patients information was collected on demographic and clinical characteristics. The subjective depressive symptoms and the objective depressive symptoms, as well as patients insight regarding psychosis were evaluated. The subjective depressive symptoms were evaluated by BDI and ZDS; the objective depressive symptoms were evaluated by HDRS and CDSS, and patient insight into the psychosis was evaluated by KISP. Results: The comparisons using demographic and clinical characteristics showed that HDRS and CDSS had significant difference with regard to gender and suicide attempts; the BDI was associated with difference in education level and age of onset. The patients with scores above cuff-off score for each scale were 20(25.0%) for the BDI, 16(20.0%) for the ZDS, 18(22.5%) for the CDSS and 6(7.5%) for the HDRS. The results of the stepwise multiple regression analysis showed that the scores for the KISP, education levels, gender and suicide attempts were the main prognostic factors in patients with the psychotic depressive disorder of schizophrenia. Conclusion: The main prognostic factors in psychotic depressive disorder of schizophrenia included: insight into psychosis, suicidal attempts. Insight into the psychosis was the most reliable prognostic factor but this characteristic had a negative relationship to the with depressive symptoms.

This study was carried out to provide basal information on factors effected the decline of Pinus thunbergii by analysisof, the content of chlorophyll, and acid deposition through stepwise regression analysis. pH in throughfall at industrial area was 4.65 in the spring and 4.72 in the fall. On the contrary, pH at rural area was measured 5.32 in the spring and 5.34 in the fall. EC of rain fall at industrial area was $262.30{\mu}s$, However, there was $47.72{\mu}s$ at control area. Of anions, the concentration of ${NO_3}^-$ was $52.13mg/{\ell}$ at industrial area and $37.85mg/{\ell}$ at area. The concentration of ${SO_4}^{2-}$ was $57.89mg/{\ell}$ at industrial area and $36.21mg/{\ell}$ at area. Of the concentration of leaf chlorophyll in Pinus thunbergii, chlorophyll a was 0.2378 but control area was 0.4378. Also the content of chlorphyll b was 0.2097 and control area was 0.2345. The degree of decline of Pinus thunbergii forest was 2.97 at industrial area and 1.20 at area. We carried out a correlation analysis between the degree of decline and the concentration of ions, $SO_2$, and $NO_2$ in Pinus thunbergii forest. As a result, there was a negative correlation (r=-0.8672) between rain acids, and a positive correlation between $SO_2$ concentrations (r=0.8924) and between $NO_2$ concentrations (r=0.8428) in air. The correlations among acid depositions at level of 1% were pH (r=-0.8672), ${NO_3}^-$(r=0.6996), ${SO_4}^{2-}$(r=0.8497), $SO_2$ (r=0.8924), and $NO_2$ (r=0.8428).

A self-sufficiency service has worked as a typical workfare policy combined with public assistance in Korea since 2000. Despite of its long history, three core pillars in administrating the self-sufficiency service, policy, research, and practice, have respectively understood the meaning of self-sufficiency in terms of their own interests. As a result, the self-sufficiency service has recently faced with its own identity issues by showing failures to its environmental changes. The current situation makes it necessary to reconceptualize the definition of self-sufficiency by exploring its in-depth understanding perceived by service providers. Specifically, we analyzed practical reflections on 35 service providers' experiences which were collected via focus group interviews for two hours. The study findings presented that service providers had two antithetical approaches towards self-sufficiency. While a dominant approach to self-sufficiency has been concentrated on improving clients' economic outcomes such as employment, job retention, the escape from welfare trap, and increasing earnings and assets, the other approach has been extended to empower clients and achieve their well-being and quality of life. Yet, these contrary perspectives have led to suffer from their role confusions and identity crisis between the work-ready process and the employment-oriented outcomes. Specifically, they described self-sufficiency in terms of psychological, social, and integrated aspects. The psychological aspect included a process of developing inner strengths, intensifying job motivation, and coping with barriers of employment. The social aspect meant a path toward social integration through recovering human relationships. The integrated aspect covered more comprehensive support for their recovery of daily life and autonomy to make a decision for their own life. In conclusion, the study findings suggest that self-sufficiency should be more extensively considered as a stepwise process towards work-ready preparations beyond ultimate economic outcomes. Such an extended concept of self-sufficiency could contribute to restructuring the whole practice of self-sufficiency including organizational and program changes in the fields.

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:The aim of this study is to investigate any differences between non-medical and medical college students for : 1) a level and the nature of perceived stress, 2) a level of life satisfaction, and 3) the related factors affecting to life satisfaction. Methods:We measured self-reported questionnaires of stress, satisfaction with life, health behavior including happiness, alcohol use, nicotine dependency and depressive symptoms in 1,714(863 non-medical and 851 medical) college students. Results:Non-medical college students had significantly higher total stress scores than medical college students(${\chi}^2$=7.66, p<.001). In non-medical college students, employment problem score was significantly higher than medical college students(t=4.07, p<.001). In medical college students, the scores of academic achievement (t=-3.81, p<.001), change of social life(t=-2.03, p<.05), death(t=-2.05, p<.05) or sickness(t=-2.60, p<.05) of friends were significantly higher than non-medical college students. And non-medical college students showed significantly lower life satisfaction scores than medical college students(${\chi}^2$=-19.05, p<.001). We also found that life satisfaction were significantly related to happiness in non-medical college students(${\beta}$=.410, $R^2$=.325, p<.001) and depressive symptoms in medical college students(${\beta}$=-.435, $R^2$=.326, p<.001) by stepwise multiple regression analysis. Conclusions:In this study, a level and the nature of perceived stress, a level of life satisfaction, and the related factors affecting to life satisfaction showed definitely differences between non-medical and medical college students. We suggest with our findings that specified mental health promotion program need for the college student's mental health management.

Purpose: The Dietary Reference Intakes for Koreans (KDRIs) suggest that the goal for the intake of sodium should be less than 2,000 mg, which is thought to be infeasible to achieve when eating the typical Korean diet. This study aimed to obtain the new intake goals for sodium with improved feasibility to achieve, and also to design optimized food intake patterns for Korean adults by performing linear programming. Methods: The data from a one day 24-hour dietary recall of the 2010 ~ 2014 Korea National Health and Nutrition Survey were used to quantify food items that Korean adults usually consumed. These food items were categorized into seven groups and 24 subgroups. The mean intakes and intake distributions of the food groups and the food subgroups were calculated for eight age (19 ~ 29, 30 ~ 49, 50 ~ 64, and over 65 years old) and gender (male and female) groups. A linear programming model was constructed to minimize the difference between the optimized intakes and the mean intakes of the food subgroups while meeting KDRIs for energy and 13 nutrients, and not exceeding the typical quantities of each of the food subgroups consumed by the respective age and gender groups. As an initial solution of the linear programming, the optimized intake of seasonings, including salt, was calculated as 0 g for all the age and gender groups when the sodium constraint was inserted not to exceed 2,000 mg. Therefore, the sodium constraint was progressively increased by 100 mg until the optimized intake of seasoning was obtained as the values closest to the $25^{th}$ percentile of the intake distribution of seasonings for the respective age and gender groups. Results: The optimized food intake patterns were mathematically obtained by performing linear programming when the sodium constraint values were 3,600 mg, 4,500 mg, 4,200 mg, 3,400 mg, 2,800 mg, 3,100 mg, 3,100 mg, and 2,500 mg for the eight age and gender groups. Conclusion: The optimized food intake patterns for Korean adults were designed by performing linear programming after increasing the sodium constraint values from 2,000 mg to 2500 ~ 4,500 mg according to the age and gender groups. The resulting patterns suggest that current diets should be modified to increase the intake of vegetables for all the groups, milk/dairy products for the female groups, and fruits for the female groups except for the females aged 50 ~ 64 years.

'Arirang folk song in the Democratic People's Republic of Korea' was inscribed to the Representative List of the Intangible Cultural Heritage of Humanity in 2014 and 'Tradition of kimchi-making in the Democratic People's Republic of Korea' followed in 2015. It is presumed that North Korea was influenced by the Republic of Korea inscribing 'Arirang, lyrical folk song in the Republic of Korea' to the list in 2012 as well as 'Kimjang, making and sharing kimchi in the Republic of Korea' in 2013. These cases show the necessity (or possibility) of cultural exchanges between the two Koreas through UNESCO ICH lists. The purpose of this article is to explore the possibility of inter-Korean cultural integration. Therefore, I would like to review UNESCO's ICH policy and examine the ways of cooperation and joint nominations to the Representative List of Intangible Cultural Heritage of Humanity between the two Koreas. First, I reviewed the amendments to the laws and regulations of the two Koreas and how the two countries applied the UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage. Although the cultural exchange is a non-political field, given the situation between South and North Korea, it is influenced by politics. Therefore, we devised a stepwise development plan, divided into four phases: infrastructure development, cooperation and promotion, diversification, and policymaking and alternative development. First a target group will be needed. In this regard, joint nominations to the Representative List of the UNESCO Intangible Cultural Heritage of Humanity will be suitable for cooperation. Both countries have already started separate nominations on shared ICH elements to the UNESCO lists. Therefore, I have selected a few elements as examples that can be considered for joint nominations. The selected items are makgeolli (traditional liquor), jang (traditional soybean sauce), gayangju (homebrewed liquor), gudeul (Korean floor heating system), and jasu (traditional embroidery). Cooperation should start with sharing information on ICH elements. A pilot project for joint nomination can be implemented and then a mid-term plan can be established for future implementation. When shared ICH elements are inscribed on UNESCO ICH lists, various activities can be considered as follow-ups, such as institution visits, performances, exhibitions, and joint monitoring of the intangible cultural heritage. Mutual cooperation of the two Koreas' intangible cultural heritage will be a unique example between the divided countries, so its value will be recognized as a symbol of cultural cooperation. In addition, it will be a foundation for cultural integration of the two Koreas, and it will show the value of their unique ICH to the world. At the same time, it will become a good example for joint nominations to the Representative List recommended by UNESCO.

In this paper, the researcher investigated the standpoint of Lee EonJeok(李彦迪), also known as HoeJae(晦齋), with regard to interpretation of Daxue("大學"), through Daxuezhangjubuyi("大學章句補遺") and XuDaxuehuowen("續大學或問"). It is true that HoeJae accommodates a fairly large portion of interpretations made by Zhuzi, however, he strived to pass over Zhuzi's Daxuezhangju by attempting a new interpretation on the Gewuzhizhi(格物致知). The greatest reason that HoeJae couldn't admit Zhuzi's view was derived from the differences in interpretation of Gewuzhizhi. The differences between Zhuzi and HoeJae concerned with Gewuzhizhi is that, while Zhuzi perceived the objects thereof from the perspective of Li(理) of things(事物), HoeJae considered the root and branch, the beginning and end of the physical world(萬物) and also all events(萬事) as the subjects of Gewuzhizhi. Meanwhile, having the chapter, dubbed, 'Weyoubenmo'(物有本末), and the chapter, 'ZhiZhi'(知止) also as expositions of Gewuzhizhi, HoeJae was able to avoid such critiques as that he complemented or added new topics to the sutra. In addition, he could have clarified the stepwise elucidations of Sangangling(三綱領) and Batiaomu(八條目) edited and compiled by Zhuzi(朱子). And the issues in the chapter of Tingsong(聽訟) lies on the extended line of theory of Gewuzhizhi. In the end, it suggests that the differences between Zhuzi and HoeJae are arisen from the discrepancies of interpretation on Gewuzhizhi. HoeJae proposed his ideology concerned with Zhizhizhuyi(至治主義) through his book, XuDaxuehuowen, and he stressed that Ren(仁) must be foundation in order to Pingtianxia(平天下). Furthermore, HoeJae emphasized that Ren which is the founding virtue in order for Pingtianxia must be begun with such very basic behavioral practices, known as, Xiao(孝), Ti(弟), and Ci(慈), and that such desirable states would be accomplished through relationships with others, not merely through self-endeavors or by self-ego.

Since the early 2000s, Korea has continued to increase the proportion of the elderly population due to low fertility and increased life expectancy. As a result, Korea has now entered the aging society. Because of this demographic change, proportion of active elderly have increased, and many academics, such as sociology, economics, and psychology, have conducted various studies on the active elderly. This study focused on active elderly based on the activity theory of old age and the positive effect of small community participation activity on the elderly. The purpose of this study is to examine whether active elderly' participation in everyday activities, small community participation of the elderly affect citizen participation actively in society as a citizen, and in the process, mediates the effect of small community cohesion and the moderating effect of small community selfishness. This study performed a stepwise regression analysis and a hierarchical regression analysis of 700 elderly people who are participated actively in various small communities. As a result, the partial mediating effect of small community cohesion was shown in the relationship between participation in everyday activities and citizen participation, and the moderating effect of small community selfishness was also shown. These findings suggest that government and interested parties need to develop and implement policies for the small community participation of elderly citizens in consideration of their small community activities, small community cohesion and small community egoism.

This study was conducted to evaluate the manufacturing process of non-sintered cement for the safe containment of radioactive waste using low level or ultra-low level radioactive waste soil generated from nuclear-decommissioning facilities, clay minerals, and blast furnace slag (BFS) as an industrial by-product recycling and to characterize the products using mineralogical and morphological analyses. A stepwise approach was used: (1) measuring properties of source materials (reactants), such as waste soil, clay minerals, and BFS, (2) manufacturing the non-sintered cement for the containment of radioactive waste using source materials and deducing the optimal mixing ratio of solidifying and adjusting agents, and (3) conducting mineralogical and morphological analyses of products from the hydration reactions of manufactured non-sintered cement solidifier (NSCS) containing waste concrete generated from nuclear-decommissioning facilities. The analytical results of NSCS using waste soil and clay minerals confirmed none of the hydration products, but calcium silicate (CSH) and ettringite were examined as hydration products in the case of using BFS. The compressive strength of NSCS manufactured with the optimum mixing ratio and using waste soil and clay minerals was 3 MPa after the 28-day curing period, and it was not satisfied with the acceptance criteria (3.44 MPa) for being brought in disposal sites. However, the compressive strength of NSCS using BFS was estimated to be satisfied with the acceptance criteria, despite manufacturing conditions, and it was maximized to 27 MPa at the optimal mixing ratio. The results indicate that the most relevant NSCS for the safe containment of radioactive waste can be manufactured using BFS as solidifying agent and using waste soil and clay minerals as adsorbents for radioactive nuclides.
