The purpose of this study is to investigate the effect of government support policy for traditional markets. The measurement analysis method used in this study is the multiple regression model. This study intends to perform a questionnaire survey on traditional market consumers to measure their satisfaction levels and verify the effect of traditional market support policy for empirical analysis. The product satisfaction, facility satisfaction, brand perception satisfaction and the crowdedness satisfaction etc., were statistically significant among the psychological factors. It was shown that as the consumers have higher product satisfaction in traditional markets. government policy will be needed which focuses not only on the direction of policy support or improvement of the physical environment, but also the securing of convenient flows of movement of consumers within a shopping environment.

Purpose: This study was performed in order to determine the changes over time in preventable and potentially preventable traumatic death rates, and to assess the factors that affected the deaths of trauma patients which occurred in Korean pre-hospital and hospital settings. Methods: All trauma deaths occurring either in the emergency department (ED) or after admission at twenty Korean hospitals between August 2009 and July 2010 were retrospectively analyzed. The deaths were initially reviewed by a team of multidisciplinary specialists and classified into nonpreventable,potentially preventable, and preventable deaths. Only preventable and potentially preventable deaths were the subject of our analysis. Structured data extraction included patient demographics, vital signs, injury severity, probability of survival, preventability of mortality,reported errors in the evaluation and management of the patient, and classification of error types (system, judgment,knowledge). Results: During the study period, 446 trauma victims died in the ED or within 7 days after admission. The mean age was 52 years, 74.1% were men and the mean time from injury to death was 35.6 hours. The most common cause of death was head injury (44.7%) followed by hemorrhage (30.8%) and multi-organ failure (8.0%). The rates of preventable/potentially preventable deaths were 35.2% overall and 29.8% when limited to patients surviving to admission. Of all death classifications, 31.2% were potentially preventable and 4.0% were preventable. Errors leading to preventable death occurred in the emergency department (51.2%), pre-hospital setting (30.3%) and during inter-hospital transfer (60.8%). Most errors were related to clinical management (48.4%) and structural problems in the emergency medical system (36.5%). Conclusion: The preventable death rates for Korean trauma victims were higher than those found in other developed countries, possibly due to poorly established emergency medical systems for trauma victims in pre-hospital and hospital settings. A system wide approach based on the emergency medical system and well-developed in-hospital trauma teams should be adopted in order to improve the quality of care of trauma victims in Korea.

The purpose of this study is to examine the effect of organizational justice as a antecedent variable of SMEs' dynamic capabilities, and to analyze the mediating effect of dynamic capabilities between organizational justice and management performance. For this study, 337 questionnaires were used, and SPSS 26 for basic analysis and Smart PLS 3.0 for testfying the hypotheses were used as analysis methods. The results show that distributive justice and procedural justice had a positive (+) effect on dynamic capabilities, and that interaction process does not have significant positive (+) effect statistically. In addition, it was found that dynamic capabilities played a mediating role in the relationship between distribution justice and procedural justice on management performance, but dynamic capabilities did not play a mediating role in the relationship between interactional justice and management performance. As an academic implication, the impact on management performance was approached in an integrated way by discovering and proving organizational justice as an antecedent factor for dynamic capabilities. In practice, SMEs will enhance organizational justice as well as secure dynamic capabilities, and it will be necessary to prepare various programs to create a fair organizational culture in terms of personnel management.

Contribution spending is one of the major corporate social responsibility activities and a decision making that is heavily influenced by management discretion. Thus, identifying what factors play an important role in contribution decision-making may provide a clue about its purpose. Extending to previous studies that peer firms critically affect various decisions such as investment and finance, this study investigates whether peer effects exist in terms of contribution spending. Specifically, we examine whether the contributions of the most reputable companies are related to those of peer firms belonging to the same industry (3-digit KSIC), and analyze the effect of peer firms’ contributions on corporate value. The most reputable companies are defined as All Star 30 firms selected annually by Korea Management Association Consulting, KMAC), consistent with prior studies. Empirical results using 9,242 firm-years from 2012 to 2017 show that contributions are the largest in the most reputable companies, followed by peers and non-peers and that donations of the most reputable companies have a significantly positive association with those of peer firms. This indicates that the contribution spending of the most reputable companies is an important factor in donation decision-making of peers, suggesting the existence of peer effects in terms of donation. We also analyze the impact of contributions on corporate value for the most reputable companies, peers, and non-peers subsample, respectively, and find that the first two groups have no significant results while donations of non-peers are positively related to firm value, corroborating the above peer effects. This study extends the literature by adding peer effects in terms of donation. Our results suggest that investors should pay attention to peer firms which mimic donation behavior of the most reputable companies because contributions of peers are not related to their firm value. The findings also indicate that regulatory authorities need to closely monitor corporate social responsibility activities considering the influence of leading firms, such as the most reputable companies, on their peers. 기부금 지출은 대표적인 기업의 사회적 책임활동으로 경영자의 재량에 영향을 많이 받는 의사결정 사항이므로 기부금 지출 유도 요인을 살펴보는 것은 기부금 지출 목적이나 그 효과를 파악하는 데 중요한 실마리를 제공할 수 있을 것이다. 본 연구는 기업의 투자, 재무 등 여러 의사결정에 동료기업의 영향이 중요하게 작용한다는 선행연구를 바탕으로, 기업의 기부금 지출 의사결정에 있어서도 동료효과가 존재하는지를 살펴보았다. 구체적으로, 명성이 높은 기업의 기부금 지출과 동종산업에 속한 동료기업들의 기부금 지출 간에 관련성이 있는지를 검토하고, 이들 동료기업의 기부금 지출이 궁극적으로 기업가치에는 어떤 영향을 미치는 지를 분석하였다. 2012년부터 2017년까지 9,242 상장기업-연도를 대상으로 분석한 결과, 기부금 지출액(매출액 대비)은 명성 높은 기업이 가장 많고, 동료기업, 비동료기업 순의 크기를 보였으며, 명성 높은 기업의 기부금과 동료기업의 기부금 간에는 유의한 양(+)의 관련성이 나타났다. 다음으로, 기부금 지출이 기업가치에 미치는 영향을 살펴본 분석에서는 비동료기업의 기부금 지출은 기업가치에 긍정적인 영향을 미치는 것으로 나타났으나, 동료기업의 기부금 지출은 기업가치에 유의한 영향을 미치지 못하는 것으로 나타났다. 이는 기부금 측면에서 동료효과가 존재함을 실증하는 결과임과 동시에 동료효과에 기인한 기부금 지출은 기업가치 제고에 직결되지 않을 수 있음을 시사하는 결과이다. 본 연구는 사회적으로 명성이 높은 기업들의 사회공헌활동이 동료기업의 활동에도 영향을 미치는 동료효과를 실증함으로써 선행연구를 확장하는 한편 기업들의 사회공헌활동을 독려하는 유관기관의 정책수립이나 모니터링 역할에 유용한 시사점을 제기하고 있다. 다만 명성이 높은 기업이나 이를 모방한 동료기업의 기부금 지출이 기업가치 증가로 연결되지 않을 수 있는 결과는 이들 기업의 경영자 및 투자자들에게 각별한 주의를 환기시키고 있다.

Purpose: We report our experience with laparoscopic radical prostatectomy (LRP) and investigate the learning curves for various outcome variables for LRP. Materials and Methods: From January 2005 to March 2008, 47 patients with prostate cancer with a clinical stage ≤T3a underwent LRP by a single surgeon. We retrospectively reviewed the medical records of the patients regarding to the surgical, oncological, and functional outcomes. Results: The median follow-up for the entire group was 38 months (18-49). In surgical outcomes, the operative time was decreased to less than 300 minutes after 5 cases and the estimated blood loss was stabilized after 30 cases. The positive surgical margin rate was decreased within the first 30 cases, but not significantly so. For functional outcomes, the urinary continence rates at 1 month, 3 months, 6 months, and 1 year postoperatively were 17.0%, 53.2%, 72.3%, and 80.9%, respectively. Neurovascular bundle saving was performed in 11 cases (23.4%). In cases of neurovascular bundle saving, the potency rates at 3 months, 6 months, and 1 year postoperatively were 27.3%, 27.3%, and 54.5%, respectively. Analysis of the learning curve for functional outcome revealed no statistical differences in the continence rate or potency rate with time. Conclusions: In the present study, the learning curve for operative time was overcome within the first 5 cases, and estimated blood loss took 30 cases to reach a plateau. The longest learning curve was for functional outcomes such as continence and potency, which did not stabilize until 47 cases.
