강다연 ( Dayeon Kang ),전영서 ( Youngseo Jeon ) 한국국제경제학회 2015 국제경제연구 Vol.21 No.3

This study shows the economic effects of Korea and Japan FTA through the panel gravity model and DD (Difference in Difference), DDD (Difference in Difference in Difference) estimator. The data structure is estimated for exports and imports using an annual panel data set covering 128 countries for 1990~2013. According to the results of the analysis, firstly, the result shows Korea and Japan trade similar to the basic gravity model. It means GDP and GDP per capital have positive relationship with trade volumes but distance has negatively significant impact on it. Secondly, in order to control the specificity of Korean and Japanese, we need exchange rate variable which has a positively significant impact on Japan trade while Korea trade has negatively significant impact on it. It shows the ratio of import is higher than export in the Japan’s total trade volumes but Korea trade has the opposite effects. Thirdly, as a result of the DD estimator, there is a promotion effects on the trade when we compare the FTA conclusion to preparing the FTA with Korea and Japan. Especially, the DDD estimator result reflects Korea FTA effect is more effective than Japan FTA.

최근 발생한 고객정보유출사고는 조직의 정보보안 강화에 대한 관심과 전담조직의 중요성을 고조시키고 있다. 이에 따라 기업들은 정보보안 강화를 위해 정보보안정책을 마련하고 있으며, 조직구성원들로 하여금 보안정책을 준수하도록 권고하고 있다. 해운항만 조직에서도 정보보안을 위해 정보보안정책을 체계화시키고 조직구성원들의 정보보안능력과 정보보안행동을 평가할 필요성이 있다. 본 연구의 목적은 해운항만조직 구성원들을 대상으로 정보보안정책 준수 정도가 정보보안능력과 정보보안행동에 미치는 영향을 분석하는데 있다. 분석결과, 먼저 해운항만조직 구성원의 정보보안정책 준수에 영향을 미치는 요인으로 정보보안규범과 정보보안교육을 확인할 수 있었고, 정보보안처벌은 정보보안정책 준수에 유의한 영향을 미치지 않는 것으로 분석되었다. 해운항만조직 구성원의 정보보안정책 준수정도는 정보보안능력과 정보보안행동에 유의한 영향을 미치는 결과를 확인할 수 있었다. Recent accidents of customer information leakage increase the necessity of information security for organization and the importance of information security team for it. To strengthen information security, organizations make information security policy and ask the members to comply with it. In this regard, maritime organization also needs to structure information security policy and examine its ability and behavior. The purpose of this study is to analyze the effects of compliance with information security policy on the ability and behavior of workers in shipping and port organization. The results of investigation show that information security education and norm affect compliance with information security of the workers. On the contrary, the punishment of information security is insignificant. It is shown that the degree of compliance with information security significantly affects its ability and behavior of the workers in shipping and port organization.

강다연(Dayeon Kang),장활식(Hwalsik Chang),김종기(Jongki Kim) 한국콘텐츠학회 2009 한국콘텐츠학회논문지 Vol.9 No.4

많은 기업들이 ERP시스템 도입하여 사용함에 따라 ERP의 성과에 대한 관심이 증가하고 있으며, 객관적인 성과 측정의 필요성을 느끼고 있다. 본 연구는 국내 기업의 ERP 도입으로 인한 성과를 정성적인 성과와 정량적인 성과 간의 상관관계를 분석하고자 한다. 즉, 본 연구는 ERP시스템 도입성과 측정을 위해 경영정보시스템 분야에서 주로 사용하고 있는 시스템 만족도 등과 같은 사용자에 의해 인지된 성과와 회계학에서 주로 사용되고 있는 ERP관련 정량적 성과 변수들 간의 관련성을 실증 분석하여, 두 변수 집단간의 관련성을 검토하고자 한다. ERP의 정성적 성과를 분석하기 위해 시스템 품질, 정보품질, 업무의 만족도, 업무개선 정도 등의 변수를 사용하였으며, 정량적 성과를 분석하기 위해 재고자산회전율, 매출액 대비 재고자산, 매출액 대비 종업원 수, 매출액 대비 인건비, 총자산 순이익률 변수를 사용하였다. 실증분석 결과는 다음과 같이 요약될 수 있다. 첫째, ERP 도입의 측면의 정성적인 성과 변수간의 상관관계는 통계적으로 유의하게 분석된 것이다. 둘째 정량적인 성과 변수간의 상관관계는 ERP 도입 전ㆍ후의 평균의 값을 통하여 ERP 도입의 성과를 분석한 결과 통계적으로 유의한 상관관계를 나타내고 있었다. 끝으로 정성적인 성과와 정량적인 성과의 상관관계는 통계적으로 유의하지 않은 상관관계로 분석되었다. As many companies have adopted and used ERP systems, concerns about ERP performance also have increased. The purpose of this research is to examine the relationships between qualitative variables and quantitative variables measuring ERP performances. Qualitative research, widely used in MIS research, typically examines perceived usefulness of ERP, such as information quality, system quality, system satisfaction. Quantitative research, often done in accounting research, usually examines ERP performance based on financial statements. An empirical study led to the following conclusions: 1) There were significant correlations among the qualitative variables measuring perceived usefulness of ERP; 2) Significant correlations were also observed among the quantitative variables based on financial statements; 3) However, no significant correlations was found between the qualitative variables and quantitative variables measuring ERP performance.

Objectives : Virus infection through the respiratory tract causes various inflammatory diseases such as pneumonia, cystic fibrosis, and obstructive pulmonary disease, causing enormous social damage. Therefore, it is very important to develop a treatment and prevention of infectious diseases. In this study, we investigated the effect of water extracts of Liriope muscar i (WELM), known to improve lung function, on the inflammatory response of lung carcinoma cell line A549 cells induced by the viral double stranded RNA mimetic Polyinosinic:polycytidylic acid (Poly I:C). Methods : The cell viability by WELM treatment was analyzed using MTS assay in A549 cells. After inducing an inflammatory response to WELM-treated A549 cells with Poly I:C, the degree of apoptosis was confirmed through bright field microscopy. Interferon beta (IFN-β) mRNA expression level in A549 cells was analyzed by quantitative reverse transcription PCR (qRT-PCR). Results : WELM treatment has no significant effect on cell viability of A549 cells. We confirmed that pre-treatment of WELM effectively reduces the Poly I:C-induced apoptotic cell death in A549 cells. In addition, it was confirmed that the mRNA expression level of IFN-β, a pro-inflammatory cytokine increased by Poly I:C treatment, was significantly suppressed by WELM treatment in A549 cells. Conclusions : These results provide the evidence that WELM is effective at inhibiting inflammation on respiratory viral infections and suggest that Liriope muscari might be a valuable natural substance in the prevention and treatment of infectious diseases.

Purpose: to investigate learners’ perceptions of non-literary texts in CSAT, the factors and demands for perceived difficulty, and to seek directions to improve non-literary texts. Methods: achieve the study’s goal, two interviews with four high school students and one dropout in Busan and Gyeongnam were conducted to examine the learners’ experiences, evaluations, and demands regarding nonliterary texts. Results: Learners’ perceptions of non-literary texts were as follows: ① Emotional responses when reading non-literary texts were positive (relief, interest, and stability), negative (fear, instability, skepticism, and rejection), and non-responsive (adaptive). ② Factors that hinder reading non-literary texts include the length of texts, unfamiliar vocabulary, test situations, lack of background knowledge, abundance of information, and personal interest. Non-literary texts are evaluated as either positive or negative, based on their difficulty and whether their reading ability has improved . Learning activities desired by learners were divided into cases aimed at improving reading ability and cases aimed at the CSAT. Conclusion: To discuss ways to improve nonliterary texts, learners’ negative emotional reactions to nonliterary texts must first be resolved. Second, the complexity of non-literary texts must be regulated. Third, the materials and contents of non-literary texts must be reviewed.

This study investigates the validity and reliability of the mental toughness scale(MTS) for middle school students. The subjects were 593 middle school students in Seoul, Korea. The MTS, which was originally developed by Clough et al.(2002) for athletes, was revised to be suitable for middle school students and were applied to them. The MTS scale was verified and refined through exploratory and confirmatory factor analyses. As a result, the MTS scale consisted of five factors(i.e., challenge, commitment, confidence in ability, active emotion control, and passive emotion control) with 33 items. Convergent validity was supported through correlations among educational stress, depression, life satisfaction, self-esteem, and optimism. Implications of this study were discussed in terms of educational settings.

In this study, we analyzed the changes in the species composition of fishes inhabiting the tidal flat off the Ganghwa Island by collecting fish assemblages monthly from November 2014 to October 2015 with a fence net and compared with a study performed about 15 years ago in 1998~1999. A total of 25 species, 970 individuals, and 65,507.7 g of fish were collected in this study, of which 68% were dermersal fish and 32% were pelagic fish. Among the collected fish, the dermersal fish, Synechogobius hasta, ranked highest in both number of individuals (31.6%) and biomass (34.1%), while the pelagic fish, Chelon haematocheilus, ranked the second highest in both number of individuals (16.1%) and biomass (29.6%). Comparing the results of the present study (2014~2015) to those of the 1998~1999 study, which was conducted approximately 15 years earlier, two fewer species were present, abundance and biomass declined significantly, and the composition, ranking, and species dominance of the dominant species were different. Furthermore, cluster analysis and nonmetric multidimensional scaling (nMDS) analyses of the 2014~2015 and 1998~1999 collections revealed a relatively low level of similarity (54%) between the two studies. These results suggest that the species composition of the tidal flat off the Ganghwa Island in 2014~2015 has changed significantly compared to 1998~1999, about 15 years ago, which may be related to global-scale environmental changes such as water temperature changes and anthropogenic environmental changes such as various coastal development in nearby seas.
