각 국은 국제무역 및 물류에 있어서 항만의 역할과 가치의 중요성에 주목하면서 자국 항만의 경쟁력을 강화시키기 위한 정책과 전략을 추진하고 있다. 본 연구의 목적은 전 세계 컨테이너물동량의 대부분을 차지하고 있는 3개 지역, 즉 동아시아, 유럽, 북미지역의 주요 컨테이너항만의 효율성을 비교하고 효율성에 영향을 미치는 요소들을 분석하여 제시하는데 있다. 효율성을 비교분석하기 위해 45개 항만을 대상으로 5개의 투입요소와 2개의 산출요소를 가지고 DEA 모형을 이용하였다. 또한 처리물량, 총 효율성, 기술적 효율성, 규모의 효율성 각각에 영향을 미치는 요소를 분석하기 위해 회귀분석을 실시하였다. 분석결과 동아시아 항만이 유럽과 북미의 항만보다 규모가 작음에도 불구하고 더 많은 성과를 내고 있으며 기술적으로나 규모면에서 상대적으로 더 효율적으로 나타났다. 본 연구의 분석이 지역별 항만의 특징과 효율성을 이해하는데 도움이 되고, 각 지역의 항만의 이용과 발전방향의 설정에 참조가 되기를 기대한다.

Objectives : The purpose of this study is to establish the regular scaling checkup service and to improve oral health care on the basis of knowledge, attitude, and belief by Dental Prophylaxis Practice Lab in A university. Methods : Subjects were 324 patients who visited Dental Prophylaxis Practice Lab in A university for the preventive removal of tartar from April to June 8, 2012. Data were analyzed using SPSS version 18.0 through the frequency analysis, chi-test, and logistics regression analysis. Results : In relation to scaling experience by age, 65.3% had experienced scaling checkup and those between 20 to 29 (34.7%) did not receive the scaling therapy. Smokers tended to have received more scaling experience than nonsmokers. Second, the number of untreated dental caries and missing teeth due to dental caries were important because the variables of oral health condition affected the scaling experience. Conclusions : It is necessary to increase the scaling experience and regular dental checkup by providing the education to improve dental clinics visit based on the knowledge and belief towards the scaling.

Purpose - It seems common sense that corporate social responsibility (CSR) is a key driver of business sustainability. Nevertheless, there has been little research on the performance of socially responsible activities, including economic and environmentally responsibility activities, in internationally diversified firms. Design/methodology - The purpose of this study was to evaluate the effects of CSR activities on management performance. For this evaluation, an empirical analysis was conducted with total of 2,520 cases, selected from companies listed on the Korea Composite Stock Price Index market for six years from 2013 to 2018. As proxies for management performance, financial data such as a total asset net profit ratio and a total asset operating ratio were used. A multivariate regression analysis was conducted to test hypotheses. Findings - The results of this analysis indicated that firms in the CSR outstanding group were ranked significantly higher than other groups in management performance. In addition, CSR activities of internationally diversified firms positively influenced the total asset net profit ratio and total asset operating ratio. Originality/value - The results suggest that the CSR activities of these firms can play a significant role in enhancing management performance in the economic status of Korea, where the degree of export dependency is high.

본 연구에서는 1999년부터 2014년까지 통계청에서 조사한 생활시간조사 자료를 활용하여 조사연도별로 평일 통행시간예산에 영향을 미치는 요인을 분석하여 이를 비교하고자 하였다. 먼저 인구 및 인구 및 사회경제지표, 비가정 활동시간 등을 비가정 활동시간 등을 고려한 통행시간에 관한 다중회귀모형을 구축하여 영향력을 분석하였다. 모형추정 결과, 가구특성, 개인특성, 비가정 활동시간 변수들이 통행시간에 유의하게 영향을 미치는 것으로 분석되었으며, 연도별로 영향력에 차이가 있음을 확인하였다. 또한, 통행시간과 비가정 활동시간간의 상관성을 고려하여 SUR모형을 구축하였으며, 독립변수들이 미치는 영향력을 시계열적으로 비교·분석하였다. 전반적으로 인구 및 사회경제지표가 통행시간은 물론 비가정 활동시간들에 지속적으로 영향을 미치고 있는 것으로 나타났다.

우리나라 도시근로자의 가계소득과 외식비는 함께 증가하고 있으나, 시간이 경과와 더불어 가계소득에 비해 외식비 증가율이 크게 둔화되고 있을 뿐만 아니라 가계소득에서 외식비가 차지하는 비율도 감소하고 있다. 이러한 외식비 지출패턴의 변화는 소득계층에 따라서도 달라 외식비가 가계소득에서 차지하는 비중은 2005년 이후 감소하나 10분위의 외식비 비중이 가장 낮고 1분위의 비중이 가장 높다는 것과, 외식비 비중의 표준편차도 소득계층이 높을수록 작고 소득계층이 낮을수록 크다는 것을 보인다. 외식비모형에 회귀분석을 적용하여 소득계수가 모두 유의하며 소득분위가 높을수록 계수의 크기가 작다는 것과 외환위기는 1분위와 10분위를 제외하고 음의 부호로 유의하다는 것을 밝힌다. 1분위와 2분위에서는 계절에 따른 외식비 변화가 없으며, 소득계층이 높을수록 계절에 따른 외식이 분명해진다는 것도 제시한다. 시간이 흐름에 따른 외식비 패턴의 변화를 살펴보기 위하여 전향적 이동회귀를 실시하여 단순 추정에 따른 것보다 훨씬 빠른 속도로 외식비의 소득탄력성 감소가 이루어지고 있다는 것을 밝힌다. 외식비를 분산분해하여 소득수준이 낮은 계층에서는 소득이 중요한 변수이나 소득수준이 높은 계층에서는 소득 이외의 요인들이 외식비에 많은 영향을 미친다는 것을 보인다.

Recently, local governments that provide mobile-based public delivery app services have been increasing a lot. The purpose of this study is to analyze whether the restaurant self-employed's public delivery app selection attributes and public institutions' perception of support, which are under economic pressure due to the high delivery fee burden of private delivery apps, affect the intention to use public delivery app services. In this study, the degree of perception of each factor was measured using the Likert 5-point scale, and it was verified through statistical analysis using SPSS. The effect of the selection attribute of public delivery apps and the perception of self-employed people in the restaurant industry on the intention to use the service was empirically analyzed, and the hypothesis was verified using regression analysis. As a result of this study, it was confirmed that convenience, economy, and public interest had a significant effect among the factors of public app selection attributes, and educational support had a significant effect on public institution support.

Background: This study aimed to explore the associations of social-demographic, health-behavioral, and woman-specific factors with the non-screening status of the cervical cancer screening test in Korean adult women. Methods: This study was a cross-sectional analysis of 9,698 Korean adult women aged 20 years or more who participated in the Korea National Health and Nutrition Examination Surveys V (2010-2012). Rao-Scott chi-square tests and survey logistic regression analyses were employed respectively to analyze the difference in the non-screening status of the cervical cancer screening test by each characteristic and to explore the factors related to the non-screening status. Results: The rate of the non-screening status of the cervical cancer screening test was 53.5% over the previous 2 years. In the survey logistics regression analysis, age, marital status, educational levels, income levels, residential area, occupation, private health insurance, smoking, alcohol, obesity, menstrual status, pregnancy experience, and hormone replacement therapy were significantly associated with the non-screening status of the cervical cancer screening test. Conclusion: On the basis of the results of this study, some social-demographic, health-behavioral, and woman-specific characteristics of Korean adult women seem to affect the non-screening status of the cervical cancer screening test. Therefore, appropriate health policies need to be designed, implemented, monitored, and evaluated to reduce the non-screening status of the cervical cancer screening test of them.

The study examines the impact of organizational rewards, procedure justice, and perceived supervisor support on perceived organizational support, and examine the impact of perceived organizational support on affective commitment to the organization in the logistic enterprises as well. Quantitative research is applied to measure relationships by regression analysis with SPSS. The research data was collected by convenient method from 180 employees who work in different departments in the logistics industry. The study results in the model 1 found that organizational rewards, procedure justice, and perceived supervisor support have a positive relationship to the perceived organizational support. The study results in the model 2 also found that perceived organizational support has strong impact on the affective commitment to the organization. The study results contribute to both management theory and management practice. For the management theory aspect, the authors suggest that perceived organizational support should be considered the key antecedent of affective commitment about which researchers should pay more attention as a concept. Based on the research results, the authors also recommend for the management practice that managers should pay attention to the implementation of rewards, procedure justice, and supervisor support to increase the perceived organizational support and affective commitment in the logistic enterprises.

전자무역 해외시장조사, 계약, 신용조사, 거래알선, 결제, 보험, 운송 등 무역거래 전반의 프로세스를 통합하여 구매효율성을 높이고, 시간단축 등을 통해 전자무역 업무의 효율성 및 생산성을 높일 수 있는 장점을 가지고 있다. 본 연구는 전자무역업무의 몰입 요인인 무역업체 종업원이 해외시장조사업무의 몰입, 상역업무의 몰입, e-LC업무의 몰임, 통관업무의 몰입, e-B/L 및 Logistics업무의 몰입, 결제 및 e-Nego업무의 몰입 등을 개발하여, 전자무역업무의 성과에 미치는 영향을 분석하고 있다. 분석결과, "해외시장 조사업무의 몰입", "e-LC업무의 몰입", "통관업무의 몰입"과 "e-B/L 및 Logistic 업무의 몰입" 그리고 "결제 및 e-Nego업무의 몰입"의 요인들은 전자무역 성과에 유의한 영향을 미치고 있다. 반면 "상역업무의 몰입"은 전자무역 성과에 유의한 영향을 미치고 있지 않다는 분석 결과가 나왔다. 본 연구에서 나타난 바와 같이 전자무역은 무역업체에게 유효한 효과가 있기 때문에 글로벌 전자무역과 시스템 개발에 노력해야 하며, 각 관련부처간의 시스템 연계의 통일화를 기해야 할 것이다.
