  • 우리나라 최대의 항만인 부산항의 정박지로 북항에는 집단정박지 1개와 포인트 정박지 5개가 다대포항 입구에는 포인트 정박지 1개가 그리고 남외항에는 5개의 대기정박지가 지정되어 있다. 남외항 정박지는 정박선의 크기별로 5개의 정박지로 나뉘어 있는데 특히 N-5 정박지는 2009년에 국내 최초로 항계 밖에 지정되어 운영되고 있다. 최근 남외항 정박지는 기상 악화 시 주묘(走錨) 등으로 인한 접촉 충돌 등의 해양사고 위험 요인이 상존하고, 해운산업의 경기침체와 경영악화에 따라 장기계선 또는 감수보존 등의 선박들이 조종 불능상태로 방치되는 등 선박안전에 취약한 실정이다. 이 연구에서는 남외항 정박지의 이용현황을 분석하여 정박지 운영의 문제점을 식별하고 개선방안을 제안하고 한다.

  • The purpose of this study is to analyze the teaching-learning effect of using self-regulated learning strategy on experimental classes for the 'kinetics' unit of 10th grade science textbook. Six classes were chosen and classified into two groups: the first group, the control group, was taught with the regular laboratory activity and the other group, the experimental group, was taught with the teaching-learning method using self-regulated learning program. After the laboratory activity for the unit using self-regulated learning program, the mean values of the scientific inquiry, scientific attitudes, and performance assessment of the experimental group were larger than those of the control group. There were significant differences between the two groups in the post-test. With the results of the post-test for the experimental group, the self-regulated learning program has significant relationships on scientific inquiry, scientific attitudes, and scientific achievements.

  • The purpose of this article is to explore French 'minima sociaux', focusing its scheme, benefit determination rule and its level appreciation. First, on the its structure domain, French 'minima sociaux' presents the plural system in which there is eight categorical benefits and one general benefit. Il is the representation of the intention to guarantee minimum income for the dead zone people out of the social insurance application and also a historical product in different period, by different logic of benefits implementation. Second, comparing nine benefits based on the benefit determination rule, level of benefits for the poor without work ability is higher than one for the poor with work ability. Il represents one polarized perception toward for the poor according to have or not its work ability. Third, comparing level of 'minima sociaux' with relative poverty line, the level of the most 'minima sociaux' is placed under the poverty line. Nevertheless, it must not forget that 'minima sociaux' plays its role as the fundamental alternative for poverty alleviation, but not the only alternative. Fourth and finally, comparing with minimum income guarantee(SMIC in french), level of RMI benefit is estimated merely on the 50% of SMIC. We can consider that it is the result of the interaction of the complex factors, as the limited role of the state toward the minimum income guarantee for the RMI beneficiary and the intervention the logic of status instead of the logic of need, etc..

  • Through rail transit has many merits as a safe, environmental harmonic and scheduled transit, there are many problems to construct railroads because of the public resentment. However, there is no reasonable way to settle the conflict properly and it causes enormous social and economic losses. This paper suggests a methodology to evaluate public complaint using the AHP technique, which is generally used as the methodology to evaluate public complaint using the AHP technique, which is generally used as the Multi-Criteria Decision Making (MCDM). However, the result from the AHP has some defects to control conflicts because the interests related to railroad projects are so complex that it is hard to make people persuaded easily. Therefore, this paper suggests 'the improvement ranking method', 'the sensitive analysis', and 'the assessment of independence relationship' which can aid the basic AHP to be robust. And the AHP. modified by fuzzy method, is also suggested to apply this methodology to example rail paths in Korea.

  • Crew fatigue has been recognized as a major cause of maritime accidents. Systematic study on crew fatigue has a direct impact on the human factor, but the various measures being taken to prevent human error account for most of the causes of marine accidents situation are still insufficient. In this study, 128 people who have a variety of career and job types boarded the T/S Hanbada were analyzed the changes of fatigue during the 87-days a Maritime Silk Road Sailing Expedition. Crew fatigue was measured by period of time onboard classified as mental, physiological and physical changes through survey responses and individual interviews of nurses. Also, it was identified the fatigue factor through quantitative statistical analysis. As a result of repeated measures analysis of variance for the changes of fatigue in position and gender criteria in accordance with boarded period, the position-specific analysis was that Professor Rating group has appeared to feel more mental and physical fatigue than the student population. Also, the results of fatigability about the sex-specific analysis have been found that women feel more physical fatigue than men.

  • The aim of this study is to empirically explore the operational spillover effect among companies within chaebol groups, prominent corporate conglomerates in South Korea. Chaebols are known for their horizontal and vertical integration, fostering close collaboration among their constituent companies from a supply chain standpoint. Existing literature highlights the sharing of tangible and intangible resources within chaebol structures, leading to increased efficiency by minimizing transaction costs through resource sharing. This research investigates whether operational management performance within chaebol structures can be transmitted through cooperative resource utilization. To achieve this objective, we categorize leading companies and affiliate companies within chaebols and examine whether the operational management performance of leading companies significantly influences that of affiliate companies. Data on conglomerates, as defined by the Korea Fair Trade Commission, were collected, along with information on companies within these groups. Subsequently, the company with the highest revenue within each group was identified as the leading company, while the remaining companies were designated as affiliate companies. Our analysis reveals a significant positive relationship between the performance of inventory and facility resource management of leading companies and that of affiliate companies. This study sheds light on the transfer of operational management performance within conglomerates from a managerial perspective, underscoring the importance of reinforcing cooperation systems within the chaebol group. Furthermore, this research contributes to the academic discourse by delineating conglomerates from an operational management perspective and empirically demonstrating the transfer effect of operational management performance.

  • The purpose of this study was to investigate preschoolers' entry behaviors into a play group and the responses of the play group in relation to the structural characteristics of the group in a natural situation. The entry behaviors of 43 preschoolers and the responses of the play group were time-sampled. In addition the structural characteristics, including size and sex composition of the play group, and existence of a friend in the group, were checked. The following results were obtained. (1) The subjects used frequently participating behavior and wandering behavior among their entry behaviors. The wandering behavior increased and the participating behavior decreased as the size of the play group increased. Also, the subjects used wandering behaviors in the mixed group more than in the same-sex group or opposite-sex group. There was no difference in the entry behaviors according to the existence of a friend in the group. (2) The play group ignored 56% of the entry behaviors, and accepted 38% of them. The positive response of the group increased with decreasing size of the play group, whereas the entry bids were increasingly ignored as the size of the group increased. The mixed group ignored the entry bids more than the same-sex or opposite-sex group did. Also, in the presence of a friend in the group, the play group responded more positively than the group with no friend did.

  • This study investigate the impacts of Chinese consumers' cultural dispositions on the WOM behaviors in SNS. Specifically, cultural dispositions in the individual-level, collectivism and uncertainty avoidance, were examined as potential predictors of eWOM behaviors in SNSs. Hypotheses are tested with a sample of 164 university students in Shanghai, China. The results of the structural equation analysis reveal that chinese consumers' collectivism in the individual-level positively affects the opinion seeking behavior. And chinese consumers' uncertainty avoidance in the individual-level positively affects the opinion seeking behavior and negatively affects the opinion giving behavior. Lastly, the opinion giving behavior positively affects the pass along behavior. Theoretical and managerial implications for Internet marketers in China were presented and discussed.
