Purpose - As the global product network expands through both internationalization and diversification of the multimodal transportation system, corporate strategies have shifted to emphasize the importance of a high value-added international logistics system. To guide policies and strategies to attract relevant industries, this study aims to analyze the location competitiveness of regional logistics distribution center to serve Northeast Asia. Design/methodology - Multi-criteria techniques are considered to offer a promising framework for evaluating decision-making factors. This paper employed an analytic hierarchy process to analyze the hierarchal structure of determinants for selecting the location of a regional logistics distribution center. Adopting both qualitative and quantitative evaluations, this study suggest political implications for a regional logistics distribution center development, such as the direction of political support, service differentiation and infrastructure development. Findings - This study developed a location competitiveness evaluation model, based on the case study of the major port-cities in Northeast Asia. Evaluation model incorporates five factors underpinning 17 components extracted using factor analysis. The results revealed that the logistics factor is the most significant factor for evaluating the competitiveness of a regional logistics distribution center. The remaining factors were market, costs, and services environment. Comparing qualitative and quantitative evaluations, results provide useful insights for a regional logistics distribution center development in Northeast Asia. Originality/value - This study revealed differences between qualitative and quantitative evaluations. The finding implies that prior works on evaluation models of competitiveness has not successfully measured the gap between quantitative data and expert' evaluations. To overcome this limitation, this paper considered both actual data such as actual distance, cost, the number of companies located, and expert opinions.

Background: The presence of the lumbopelvic-hip neuromuscular chain is essential for dynamic spinal stabilization; its therapeutic effects on dynamic movements of the distal extremity segment and underpinning motor mechanism remain unknown and warrant further study on participants with low back pain (LBP). Objects: We aim to compare the effects of the broken chain exercise (BCE) and connected chain exercise (CCE) on electromyography (EMG) amplitude and onset time in participants with and without LBP. Methods: Randomized controlled clinical trial. A convenience sample of 40 nonathletic participants (mean age: 24.78 ± 1.70) with and without LBP participated in this study. All participants underwent CCE for 30 minutes, 30-minute daily. We measured EMG amplitude and onset times on bilateral erector spinae (ES), gluteus maximus (GM), hamstring (HAM), transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) during the prone hip extension (PHE) test before and after the BCE and CCE. We used multivariate analysis of variance (MANOVA) to analyze the amplitude and onset time difference between exercises (BCE and CCE) and Pearson's correlations to determine any synergistic relationship among the HAM, GM, bilateral TrA/IO, and ES muscles. The statistical analyses were used at p < 0.05. Results: MANOVA showed that CCE was more decreased on EMG amplitude in HAM and bilateral ES, while increased GM and contralateral TrA/IO than BCE (p < 0.05). MANOVA EMG onset time data analyses revealed that the main effect of the conditions was significant for all HAM, GM, and bilateral ES muscles, whereas the main effect for the group was significant only for GM and contralateral ES in healthy and LBP groups. Pearson's correlation coefficient was computed to assess the relationship between BCE and CCE on dependent variables. In most of the muscles, there was a strong, positive correlation between the two variables, and there was a significant relationship (p < 0.001). Conclusion: CCE produced more effective and coordinated core stabilization and motor control mechanism in the lumbopelvic-hip muscles in participants with and without LBP during PHE than BCE.

The purpose of this research is to investigate the effect of customer-contact employees support on service recovery efforts. Service companies should try to prevent the service failure situation from occurring, but it is realistic that the service failure occurs due to the characteristics of the service. Service recovery efforts of service providers are important because effective responses to service failures can enhance customer satisfaction despite service failures. Social support for customer-contact employees needs to improve service recovery efforts. Specifically, this study focuses on the mediation roles of job burnout and customer orientation in relationship between social support for customer-contact employees and service recovery efforts. Social exchange theory was used as the theoretical underpinning of the research model. Based on reciprocity principle, this paper suppose that support for customer-contact employees and service recovery effort are a kind of social exchange relationship. Social supports for customer-contact employees are categorized into internal and external organization. Internal organization is POS(perceived organizational support) and external organization is customer support. The research model was tested with the data gathered from the flight attendants whose emotional labor intensity was relatively high and the service failure frequently occurred. As a result of analysis, social supports for customer-contact employees classified into organizational support, supervisor support, and customer support are found to have differential impacts on job burnout and customer orientation. It has been found that job burnout of service providers is negatively affecting service recovery efforts. On the other hand, customer orientation of service providers has a positive influence on service recovery efforts. Based on the results of the analysis, we provide practical implications for effective service recovery efforts in service failure situations, and suggest the theoretical implications to explain the process of service recovery effort. Finally, limitations of the study and directions for future research are suggested.

Purpose: The purpose of this study was to investigate the influence of eHealth literacy, reproductive health knowledge, and self-esteem on early adult women's health-promoting behaviors (HPB). This study was based on Pender's health promotion model as a theoretical underpinning. Methods: Early adult women aged 18 to 35 years (n=165) were recruited by posting advertisements on social network sites for a student club and a faith-based community in Ansan, Korea. Willing individuals were invited to participate in the online survey from June 1 to June 30, 2022. Standardized instruments were used to measure HPB, eHealth literacy, reproductive health knowledge, and self-esteem. General characteristics included income level, perceived subjective health, and internet usage time. The collected data were analyzed using the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression. Results: The mean age of the respondents was 21.97±3.87 years. The total HPB score was 120.69, corresponding to a moderate level; and the total scores for eHealth literacy (30.24), knowledge of reproductive health (23.04), and self-esteem (35.62) were higher than the midpoint. The model explained 53.3% of variance in HPB, and self-esteem (β=.48, p<.001) was the most influential factor. Other influential factors were, in descending order, higher economic level, higher subjective health status, greater eHealth literacy, and less internet use time (<2 hours/day). Conclusion: In order to promote the health of early adult women, counseling or programs that positively improve self-esteem appear promising, and eHealth literacy should be considered as a way to promote HPB using information technology.

조직 학습은 벤처기업이 성공적인 혁신 창출에 필요한 지식 기반을 구축하는데 필수적이다. 하지만 이러한 벤처기업의 조직 학습이 성과 향상에 어떤 기제로 영향을 미치는지에 관해서는 더 많은 연구가 필요한 상황이다. 이에 본 연구는 벤처기업의 학습-성과 기제에 기업가적 지향성이 어떻게 작용하는지 살펴보았으며, 본 연구가 벤처기업 맥락의 연구라는 점을 고려해 두 유형의 혁신 성과 지표를 활용하였다: 기술경쟁력, 사업 성과. 본 연구는 총 218개 국내 벤처기업을 대상으로 수집한 자료를 분석하였으며, 그 결과 획득적 학습과 실험적 학습의 조직 학습을 강조하는 기업일수록 높은 수준의 기업가적 지향성을 나타냄을 확인하였다. 이는 벤처기업이 조직 학습을 많이 수행할수록 지식기반 자산을 보다 생산적으로 활용하는 기업가적 지향성이 높다는 것을 의미한다. 또한 본 연구는 기업가적 지향성이 벤처기업의 조직 학습과 혁신 성과를 완전 매개함을 확인하였다. 본 연구는 상대적으로 작은 규모와 짧은 업력으로 인해 한계에 직면하는 벤처기업이 지식을 습득하고 활용하기 위한 조직 학습을 통해 혁신 성과를 향상시킬 수 있음을 보였다는 점에서 기존 연구 및 실무에 기여한다.

Purpose: This descriptive study was designed to explore the clinical nurse's ethical value regarding human life. Method: Data were collected from September to October, 2002. Study subjects were 527 clinical nurses working in General Hospital as tertiary located in Seoul. Ethical value was measured with questionnaire developed by researchers and consisted on items regarding ethical value on human life. Result: Among the items, most nurses highly agree with the item, "When a patient requests his/her health care provider to keep his/her personal secret, the health care provider is obliged to do so." and "When a patient asks for information on his/her medicinal and dietary contents, his/her wish must be granted." Most clinical nurses mainly agree with the item. "Health care providers must always be honest to the patient and/or his/her family". However, most nurses disagree with the item, "When a patient is on the verge of death after an accident, it is justifiable to soothe his/her family by saying 'he/she is OK' instead of telling them the truth, in order to avoid a sudden shock befalling on them". Most clinical nurses mainly disagree with the items, "When a patient is on the verge of death after an accident, it is justiable to soothe his/her family by saying 'he/she is OK' instead of telling them the truth, in order to avoid a sudden shock befalling on them" and "It is justiable that various new ways of treatment should be applied to patient at his/her terminal stage to prolong his/her life, even for the purpose of research". There were significant differences in some items of ethical value according by clinical nurse's age and professional experience, current position, religion, education, marital status, continued education on ethics, and the experience of holing on life saving treatment. Conclusion: It is intensifying the notion of ethical underpinning for human rights, truthfulness is essential to a trust relationship under what circumstances. Also most clinical nurses agree with that It is essential to trust in the nurse-patient relationship, patients have the right to know and it is the ethical thing to do as health care provider.
