The objective of this study was to perform a systematic review of the literature for application of intranasal sodium citrate in the patients with olfactory dysfunction to help determine the sodium citrate treatments for this condition. Two authors independently searched the data base (Medline, Scopus, and the Cochrane database) for relevant studies from inception to January 2018. Included studies were randomized controlled studies published in English comparing topical sodium citrate application (treatment group) with saline (control group) in patients who had olfactory dysfunction. Outcomes of interest included the change of olfactory identification and threshold during 2 hours post-treatment. Three studies were enrolled in the meta-analysis. Compared with control group, treatment group did not increase posttreatment score of olfactory identification [standardized mean difference (SMD)=-0.03; 95% confidence interval (CI)=-0.29-0.24; I²=0%] and olfactory threshold (SMD=0.18; 95% CI=-0.09-0.45; I²=0%) significantly. In the degree of pre-post improvement of two outcomes, although treatment group statistically showed the significant improvement in olfactory threshold (SMD=0.30; 95% CI=0.05-0.55; I²=17%), the clinical significance of this outcome was meaningless. Similarly, there was no significant difference in olfactory identification between two groups (SMD=0.17; 95% CI=-0.11-0.45; I²=22%). Unlike the recent favorable results, our summated results presented the uselessness for the local application of sodium citrate in improving patient's olfactory function. However, we also had some limitation such as small sample size and inconsistent application methods. Therefore, larger trials and standardized methodology are needed to reach more stronger and exact results.

The reason why Small enterprise cooperatives are important in the history of cooperatives is that they provide the basis for the development of cooperatives. Small enterprise cooperatives are composed of five or more members of small business owners and has received financial support from the government through the evaluation of the business plan from 2013. In 2018, however, Small enterprise cooperatives must be evaluated for five years of performance. In this study, we surveyed Small enterprise cooperatives members in 2015 to identify motivating factors that affect the sustainability and cooperation of Small enterprise cooperatives. On conclusion, intrinsic motivation has been found to be an independent variable affecting the sustainability and collaboration of Small enterprise cooperatives.

Objectives: This study aimed to elucidate the effectiveness of long-term psychosocial intervention in reducing the disabling period of patients with major psychiatric disorders by their rehospitalization rate. Methods: Of the 210 patients with major psychiatric disorders received psychosocial interventions in a Mental Health and Welfare Center, 192 patients (147 with schizophrenia spectrum disorders, 45 with mood disorders) who received interventions more than 6 months were selected. Review of case management records was conducted to obtain information. Results: The number and length of hospitalization and the hospital days per year significantly decreased after psychosocial intervention. Additional analysis of 102 patients followed up for more than 5 years suggested that the effectiveness of the intervention persisted for a sufficient period. However, no significant difference was observed in the number of rehospitalization in 45 patients with mood disorders, though the length of hospitalization significantly decreased. In addition, the hospital days per year of 21 patients with mood disorder followed up for more than 5 years also showed no significant decrease. Conclusion: Long-term psychosocial intervention had a significant effect on reducing the number and length of hospitalization for patients with major psychiatric disorder and the effectiveness maintained for more than 5 years.

The Economic Gab-Jil, where the stronger are forcing the weaker to sacrifice, is not only a serious social problem, but also it exhausts the vitality of the national economy. Especially, the issue of 'cost reduction (CR) of delivery price' in automobile industry, and the issue of 'tolls' and 'retaliating' in the franchise business are becoming more controversial. This paper suggests some measures to rectify the problems by an analysis using a game-theoretic model. One of the ways to change the 'bad equilibrium', where economic Gab-Jil is prevalent, to the 'good equiblium' is to strengthen the bargaining power of the weak by legal and institutional measures. It is also a more market-friendly system that is self-enforcing, where the regulation is automatically enforced by the incentives of the participants, without relying solely on the enforcement power of regulatory or supervisory bodies

This study investigates the effect of the organizational preparedness for corporate entrepreneurship(OPCE) on innovative behavior, with a focus on the mediating role of resilience. Building on literature regarding the OPCE and resilience, hypotheses are developed and tested using data collected from 217 middle managers in South Korean small and medium-sized enterprises. Results show that the OPCE has both direct and indirect effects on the consequence. Resilience is also found to be positively associated with innovative behavior. It also find that resilience mediates the relationship between OPCE and innovative behavior. These findings suggest that the perception of middle managers on OPCE contributes to developing their resilience, which in turn encourages them to act entrepreneurially. Theoretical and practical implications, limitations and suggestions for future studies are presented.

The malignant peripheral nerve sheath tumor is an extremely rare soft tissue sarcoma. It is a highly malignant sarcoma, which is locally invasive, frequently leading to multiple recurrences and eventual metastatic spread. The peak incidence of disease is known to occur sporadically between the age of 20s and 50s, and is usually associated with the neurofibromatosis type I. In human body, the trunk and extremities are the most commonly involved sites, with only 8-14% of all lesions appearing in the head and neck region. We present a case of malignant peripheral nerve sheath tumor involving the right parapharynx in a 48-year-old patient who complained of headaches in the right parietal area and of dysphagia that aggravated over a month. After surgery, tumor was finally diagnosed as malignant peripheral nerve sheath tumor by histopathologic examinations. The authors report a case of malignant peripheral nerve sheath tumor in the right parapharynx with a review of the literature.

Copyright law has functioned to certify the authorship and artistic identity of an artist as well as to remunerate the artist's labor in monetary terms. However, the legal stability of copyright law may be questioned and even challenged because it shares the ground with unfixed notions of the concept of art. This study is an attempt to find theoretical argument where such instability of copyright law stems from, by looking into the theories of Aesthetics and history of arts. The first argument builds up on the ambiguity of discriminating between the Aesthetic concept of expression and idea. The second argument illuminates how new conventions of creating art work and emerging ideals of making art prevents to accommodate copyright law in the fields of art. New art forms such as conceptual art and place specific art are such examples. Increasing role of public arts projects also questions the conventional adoptions of copyright law. Arts management is closely related with this phenomena since their job is to administer the complex situation of introducing artists to the knowledge of copyright law.

The purpose of this study is examining the status of Education Welfare Priority Support Project and providing constructive strategies for future direction. In order to collect data, we have used on-line survey, in-depth interview personnels in charge of 17 school districts and open forum with municipal board members of education along with related literature review. As results, since 2003, the effectiveness of the Education Welfare Priority Support Project has been proved and the areas have been expanded. Furthermore, institutional stability has been confirmed along with the supports of enforcement ordinance of the Elementary and Secondary Education Acts and Ministry of Education Ordinances. However, since the management authority of the project has transferred to 17 provincial offices of education, it shows the tendency of that the overall programs were not fully activated and gradually stagnated. According to these issues, we proposed various implemental policy suggestions though the revision of Article 28 of elementary and secondary education-related law.

This study focuses on the evaluation on the satisfaction of school education system based on perception levels of students corresponding to school locations. Twenty eight variables concerning with school education system were selected based on literature review and six factors such as reliability, sympathy, student supporting system, teachers' ability, principal physical environments, secondary physical environments were extracted by factor analysis. Satisfaction evaluation was performed by SERVPERP model based on perception level, and differences among respondents as well as school locations were analyzed by t-test and ANOVA. The results said there is no difference on teachers' ability factors. Especially, perception levels of students in rural area were lower than those in urban area except teachers' ability and secondary physical environments factors. Most respondents dissatisfy the school education system and they have no intention to recommend their school facilities (hardware) as well as educational programs (software) to other students in different schools.
