This paper discusses the role of money in the process of capital accumulation where financial markets are impeded by contract enforcement problems in the context of overlapping generations framework. In particular, in less developed countries (LDCs) creditors may know little about the repayment capability of potential debtors due to incomplete information so that financial instruments other than money may not acceptable to them. In this paper the impediments to the operation of the private finanical markets are explicitly modelled. We argue that creditors cannot observe actual investment decisions made by the potential borrowers, and as a result, loan contracts may not be fully enforceable. Therefore, a laissez-faire regime may fail to provide the economy with the appropriate financial instruments. Under these circumstances, we introduce a government operated discount window (DW) that acts as an open market buyer of private debt. This theoretical structure represents the practice of governments of many LDCs to provide loans (typically at subsidized interest rates) to preferred borrowers either directly or indirectly through the commercial banking system. It is shown that the DW can substantially overcome impediments to trade which are caused by the credit market failure. An appropriate supply of the DW loan enables producers to purchase the resources they cannot obtain through direct transactions in the credit market. This result obtains even if the DW is subject to the same enforcement constraint that is responsible for the market failure. Thus, the DW intervention implies higher investment and output. However, the operation of the DW may cause inflation. Furthermore, the provision of cheap loans through the DW results in a worse income distribution. Therefore, there is room for welfare enhancing schemes that utilize the higher output to develop. We demonstrate that adequate lump sum taxes-cum-transfers along with the operation of the DW can support an allocation that is Pareto superior to the laissez-faire equilibrium allocation.

We evaluate two main rationales of massive policy intervention of Lee Administration in the Korean transportation fuel market: high market share of domestic refineries, perceived by the Administration as the result of high market concentration, and asymmetry in price adjustment, perceived as the result of collusion. Domestic refineries, huge in capacity and located at seaports, maintain international competitiveness in price. Considering market openness offering preferential treatment to importers, they set domestic prices competitively on the basis of MOPS prices. Yet, the price competitiveness of domestic refineries is so high that they are able to sustain high market share. We confirm that the Korean before-tax consumer prices of gasoline and diesel are lower than Japan's and the weighted averages of 27 EU countries by as much as 159KRW and 21KRW per liter in the case of gasoline and 170KRW and 63KRW in the case of diesel. Price asymmetry is caused by diverse economic and managerial reasons and, as FTC (2005) states, price asymmetry does not immediately imply exercise of market power or collusion. We analyzed price asymmetry in Korea, Japan and 14 EU countries, and found asymmetry in Korea and 11 EU countries in the case of gasoline and in Korea and 8 EU countries in the case of diesel.

Prior hardware-centered rural development projects implemented top-down rural community regeneration via the local government in accordance with central government agency policies. To improve this, software-centered projects have been promoted since 2000. With central agency-led rural development projects changing into local government-led ones, rural community regeneration has been built per village. Although rural community regeneration projects appear to have implemented a bottom-up development currently, the top-down development procedures being facilitated by the intervention of administrative institutions have not disappeared. In this regard, the purpose of this research thesis is to effectively perform bottom-up development methods that go one step further from the current process of rural community regeneration. As the research site, this thesis selected Geochang, which has difficulties in being steadily maintained and operated despite the development of various rural community regeneration projects. Subsequently, it determined the current status and substantial analysis of a project of the rural community regeneration in Geochang through 1:1 interviews with civil servants in charge of administration as well as conducted a prior study on rural resident awareness of rural community regeneration through a survey of village head members and in-depth interviews with rural residents. Based on these data, a 10 times-round table conference was held under the participation of pertinent civil servants, professionals and rural residents to select practical strategies for cooperative rural community regeneration in Geochang as five key areas: local food, culture & welfare, rural villages, community development, and urban and rural interchanges. In addition, it is considered that the project of building villages must be implemented by establishing steadfast administrative co-operation systems, strengthening rural residents' participation capacities and supporting professionals' systemic integrated operation and maintenance. By doing so, this research thesis sought to determine practical strategies in the cooperative rural community regeneration in Geochang. It is expected that bottom-up development rural community regeneration will be built and introduced in each rural community in the future.

Objectives: The purpose of this study was to investigate the relations between diabetic dietary compliance and dietary intake, physical activity and prevalence of metabolic syndrome (MS) in type 2 diabetic patients. Methods: Seventy five subjects diagnosed with type 2 diabetes visiting the D hospital in Dongducheon from May 2014 to Dec 2014 were included in this study. The subjects were divided into two groups according to their diabetic dietary compliance score (median 39); low diabetic dietary compliance (LDDC) group (n=44) and high diabetic dietary compliance (HDDC) group (n=31). Survey data collection was carried out by direct interview method. The nutrient intake, food intake and KDDS (Korean's dietary diversity score), DVS (dietary variety score) and GMVDF (grain, meat, vegetable, dairy and fruit) were analyzed using data from the 24-recall method. Metabolic parameters were obtained from the hospital records. Data was analyzed using Chi-square test and general linear model adjusted for sex. Results: The prevalence of MS was 59.7% in the participating diabetic patients. The prevalence of MS of the HDDC (39.3%) was significantly lower than that of the LDDC (72.7%). The distribution of physical activity showed a significant difference between the groups (p=0.006). The intakes of seeds and nuts of the HDDC were significantly lower than those of the LDDC. Fat and vegetable fat intakes and % fat of energy in the HDDC were significantly lower than those in the LDDC. But, carbohydrate (CHO) and potassium intake and %CHO of energy in the HDDC were significantly higher than those in the LDDC. KDDS and GMVDF showed significant differences between groups (p=0.033; p=0.012). Conclusions: Continuous intervention by specialized nutritionists for long-term self-regulation is needed for diabetic patients, and the high compliance to diabetic diet and increasing physical activity may be effective in the prevention of metabolic syndrome.

Journalism and Mass Communication as an academic field is believed more politicized one than pure literature and natural science. With the growth of the media, there follows additional opportunities for media scholars to take a part in politics as well. Few attention was given to understand the status and mechanism of political intervention either as advisers or decision makers though. This study attempts thus to fill this vacuum. For this, first of all, it examines a various types of laws related to media politics. Total number of 164 scholars who participated in 12 councils and commissions were analyzed on the following step. Research shows that there are patterns which favor Seoul National University, U.S. trained Ph. D and geographic preference to the capital. Neither academic excellence nor commitment to public interest appear to have impact on taking those positions. Taking into account media's expansion into politics, it is inevitable for media scholars to take responsibility not only in policy making but in taking leadership. Accordingly, the question of necessity is not who but how as much as manner. The authors hope this study will be a valuable opportunity to establish a kind of ethical standards in media politics.

The purpose of this study was to examine the effects of clinical convergence self-directedness practice learning program on self-directedness and competency in fundamental nursing skills in undergraduate nursing students. The study design was a non-equivalent pre-post quasi-experimental design. The participants were 80 nursing students in D city. The experimental and control groups were randomly assigned with 40 participants in each group. Interventions for the experimental group were visiting clinical practice, video recording and students' self-debriefing of what they did over the 5 days. Self-directedness and competency in fundamental nursing skills were measured 2 times (pre-, and post-intervention) over the 5 days. Independent t-test, Mann-Whitney U test and chi-square test were used for data analyses. There was statistically significant difference for self-directedness(t=12.93, p=.001) and competency in fundamental nursing skills(t=8.34, p=.021). Results indicate that self-debriefing method using video recording is an effective learning way to improve Self-directedness and competency in fundamental nursing skills in nursing students.

This study aimed to seek the way of effectively managing job stress of shift work nurses, to improve nursing performance, the influence of job stress of shift work nurses on nursing performance through convergence research. A total of 244 questionnaires obtained by a survey targeting nurses, who were doing shift work in a university hospital located in B city, in the period from March 2 to 15, 2015 were analyzed using the SPSS 21.0 program. As a result, the mean score of job stress was 3.57 points, and the mean score of nursing performance was 3.69 points. Job stress made a significant positive(+) influence on the sub-dimensions of interpersonal duty. Therefore, efforts should be made to more accurately identify shift work nurses' job stress and efficiently manage the nursing personnel. Moreover, if shift work nurses' job stress is effectively managed by preparing practical job stress management intervention programs for continuous improvement of nursing performance, high quality medical services will be provided through high quality nursing practice.

Group play for sociality is a therapeutic method involving a mixture of various factors, such as targeted activities, perceptions, and physical mobility required in daily life, through group activities to encourage self-expression for the purpose of facilitating sociality. This study was conducted in order to verify its effects by applying it to autistic adolescents who lack communicative ability with others and ultimately to improve their interpersonal relationships and sociality. This study applied a single pre- and post-test experiment design to 8 autistic adolescents with lack of sociality who use a daycare center in Daejeon. The group play for sociality program consisted of two sessions a week for 7 weeks from October to December 2013 for a total of 14 sessions. The sociality of the adolescents before and after the intervention was analyzed by the Wilcoxon signed-rank test. As a result of the study, the total grades of the E-CLAC and social maturity test showed significant changes from $39.88{\pm}6.78$ to $47.00{\pm}4.28$ and $49.96{\pm}28.00$ to $61.36{\pm}21.75$, respectively. In detail, there were significant changes in the sub-items, such as adjustment in group, following guidance, and increasing behavioral frequency. In conclusion, it was shown that the combined effect of the group activities, including group play for sociality and play activities taking into consideration the developmental stage of the participants, led to a significant improvement in the sociality of the autistic adolescents.

This study was conducted to identify factors influencing the weight control behavior of college students. The subjects included college students in the C area, and data were collected through a self reported structured questionnaire from Dec 01 to 20 of 2015. Overall, 289 subjects were analyzed. Analyses consisted of descriptive statistics, t-tests, ANOVA, Pearson's correlation analysis, and stepwise multiple regression analysis. The findings showed a prominent distortion of college students' perceptions of their bodies based on evaluation by others and obesity stress, which had special impacts on their weight control behavior. Weight control behavior, body self-awareness (r=.31, p<0.001), assessment of body by others (r=.30, p<0.001), and obesity stress (r=.43, p<0.001) were closely related to their weight control behavior. Stepwise multiple regression revealed that their weight control behavior was closely influenced by obesity stress (${\beta}=.37$, p<0.001) and assessment of body by others (${\beta}=.15$, p=0.009). These variables accounted for 20% of the weight control behavior (F=37.30, p<0.001). Overall, assessment of body by others and obesity stress were found to be predictors of their weight control behavior. These findings indicate that it is necessary to develop and implement information programs and design appropriate prevention programs that can induce healthy weight control behaviors. Such programs should include health education, as well as intervention programs to identify such predictors and help college students judge and perceive their body shapes objectively so that they control their weight in a proper manner.

The purpose of this study is to investigate the association of total cholesterol levels (TC) and the incidence of hypercholesterolemia in response to changes in BMI. The subjects included a total of 28,249 industrial workers (25,548 male and 2,701 female) aged 30-69 years old who had received regular medical check-ups at least once per year from 2002 to 2012 (over 11 years). Data from this period were categorized into a first term (2002-2005), middle term (2006-2009), and last term (2010-2012). Then, the average TC was stratified by BMI, which was obtained from the initial examination results of each individual. In addition, average changes in TC were analyzed by stratifying with changes in BMI over 10 years (starting in 2002). The annual occurrence rates of hypercholesterolemia stratified by BMI were further assessed in patients with normal ranges of TC. In all three terms, the average TC was significantly elevated in the obese group ($25.0kg/m^2$) compared to the low weight group ($18.5kg/m^2$) and the normal weight group ($18.5-25.0kg/m^2$). Similarly, the group with higher BMI presented elevated rates of hypercholesterolemia compared to the groups with low BMI. In addition, increased BMI over the 10 year period significantly influenced TC. Consequently, it is suggested that evaluation and intervention for obesity control may be needed in order to manage the risk of high serum lipid levels.
