This study aims to analyze the effects of service quality offered by automotive Ro-Ro terminal operators on customer satisfaction and loyalty. The results of the research can be used to understand how to enhance the service level in order to manage competitiveness of the terminal operators, finally resulting in global competitiveness of the automobile industry of Korea in both exports and imports. We carried out a survey on two groups: shippers (customers) and providers (related terminal operators and stakeholders). To identify and classify the factors into groups, we conducted Exploratory Factors Analysis (EFA) and Confirmatory Factor Analysis (CFA), which showed construct validity and convergent validity. We also calculated Cronbach's alpha for reliability. Five factor groups were identified: tangibles, reliability, responsiveness, assurance, and empathy. We found that empathy is the most influential factor group among the five groups, and that the other groups too exhibited similar effects. Based on the results of the survey and analyses, we can conclude that empathy is most important in automotive Ro-Ro terminals. In particular, specialties, training, experiences, and loyalty of employees are crucial factors because automotive Ro-Ro terminals significantly rely on work forces, differently from other bulk terminals and container terminals. Flexible working hours and fringe benefits for work forces can increase empathy, finally resulting in productivity and efficiency. Next, well-designed work schedules are followed, based on visibility through logistics and SCM activities in automobile export and import processes with information and communication networks.

This study aims to apply the G-theory for estimation of reliability of evaluation scores between raters on Taekwondo Poomsae rating categories. Selecting a number of game days and raters as multiple error sources, we analyzed the error sources caused by relative magnitude of error variances of interaction between the factors and proceeded with D-study based on the results of G-study for optimal determination of measurement condition. The results showed below. The estimated outcomes of variance component for accuracy among the Taekwondo Poomsae categories with G-theory showed that impact of error was the biggest influence factor in raters conditions and in order of interaction in subjects and between subjects, also impact of variance component estimation error on expression category was the major influence factor in interaction and in order of the between subjects and raters. Finally, the result of generalizability coefficient estimation via D-study showed that measurement condition of optimal level depend on the number of raters was 8 persons of raters on accuracy category, and stable reliability on expression category was gained when the raters were 7 persons.

This study quantified optimism, emotional intelligence, and depression levels, and explored potential key factors affecting the depression level in undergraduate students. We performed a survey targeting undergraduate students in two Universities at D city and S city, between April 8th and 30th of 2016. After receiving informed consent, a total of 166 university students were recruited. They were asked to fill in a self-reported questionnaire about optimism, emotional-intelligence, and depression. The data were analyzed through descriptive statistics, Pearson's correlation coefficient, and multiple regression analysis using IBM SPSS version 22.0. The data analysis results showed that the mean score for optimism was $3.67{\pm}0.51$, $3.66{\pm}0.49$, and $3.69{\pm}0.55$ for overall undergraduate students, undergraduate nursing students, and undergraduate non-nursing students, respectively. Moreover, the mean score of emotional intelligence was $3.56{\pm}0.49$, $3.53{\pm}0.49$, and $3.60{\pm}0.51$, respectively. In addition, the mean score of depression was $8.28{\pm}7.48$, $10.97{\pm}7.65$, and $5.50{\pm}5.54$, respectively. It was revealed that a strong negative correlation exists among optimism, emotional intelligence, and depression. This correlation was stronger for undergraduate nursing students than undergraduate non-nursing students. Optimism and emotional intelligence were key factors influencing depression. The degree of this influence was higher for undergraduate nursing students than undergraduate non-nursing students. In conclusion, a program that empowers optimism and emotional intelligence is necessary to manage depression for undergraduate students.

The digital culture contents is one of the fastest growing industry in Korea and it accounts for 60% of the digital contents industry. This paper attempts to analyze economic impacts of the digital culture contents industry using input-output analysis. This study investigated the production-inducing effect, value-added-inducing effect and employment-inducing effect of the digital culture contents industry based on a demand-driven model. In addition, the study dealt with the supply shortage effect and sectoral price effect of the digital culture contents industry using a supply-driven model and the Leontief price model, including the inter-industry linkage effects of 29 sectors with the digital culture contents industry sector. Some interesting findings were drawn from the study. First, production of 1.0 won in the digital culture contents industry results in production-inducing effect of 2.39542 won, value-added effect of 1.29895 won and employment-inducing effect of 0.39657 persons in other industries. Second, the supply shortage of 1.0 won in the digital culture contents industry prevents other industries from producing 0.56631 won. Third, a 1% increase in the price level of the digital culture contents industry raises the overall price level by 0.06017%. Finally, very high backward linkage effects were found, but forward linkage effects were minimal.

By employing Environmental Input-Output Table 2005, which has 76 intermediate sector and 21 energy sources, this paper analyses the flow of energy demand and $CO_2$ after estimating an induced $CO_2$ emissions from 76 industrial sectors. Index of $CO_2$ intensity($CO_2/GDP$) and other index of $CO_2$ intensity($CO_2/calory$) showed that final demand sector uses more high calory energy source. Intermediate sector used less environmental friendly energy source and emit more $CO_2$ at same calory. Industries those has high induced $CO_2$ emissions are Thermal Power($32.587CO_2-g/Won$), Cement($10.370CO_2-g/Won$), Road Transportation($7.255CO_2-g/Won$), Cokes and Other Coal Products($5.791CO_2-g/Won$), Steam and Hot water supply, Sewage, Sanitary services($4.575CO_2-g/Won$). It is shown that industry such as Iron and Steel which has low $CO_2$ intensity, high backward linkage effect and high forward linkage effect makes high induced $CO_2$ emissions. Environmental load and $CO_2$ emissions in overall economy will decrease when not high $CO_2$ intensity industry but also low $CO_2$ intensity industry makes lower $CO_2$ intensity.

This paper has two objectives. One is to understand status of the distribution industry in Korea and compare it with industrialized countries. The other is an attempt to apply input-output(I-O) analysis to investigate the economic impacts of the distribution industry in the national economy for the year 2008. In the economy as a whole, the distribution industry represented about around 15 per cent employment and accounted for near 8 percent in GDP. The employment portion of the distribution in overall industry is almost same that of US, UK, and Japan, but shared portion in GDP is at least 3 per cent below these countries. Next, a static I-O framework is employed, focusing on two topics in its application. First, the impacts of the product or investment in the distribution industry on the product, value-added, and employment of other sectors are explored by using demand-driven model. Second, the national economic impacts of the distribution industry in Korea are looked into by using open model and inter-industry analysis. It can be summarized that the distribution industry has a high production-inducing effect, more worker and employment-inducing effect, a high forward and a low backward linkage effect. Finally, the implications and limitations of this study are discussed.

This study investigates empirical issues that have received little attention in the previous research in the Korean capital market. It is to find any financial determinants on the capital structure for the firms listed in the KOSDAQ(Korea Securities Dealers Automated Quotation). Another test is performed to find any possible discriminating factors by utilizing a robust methodology, which may distinguish between the firms belonging the 'prime section' and the 'venture section' in terms of their financial aspects. Moreover, the null hypothesis that the changing trend or movement of a firm's capital structure with respect to its industry mean (or median) may be random, is also tested. For the book-value based debt ratios, size(INSIZE), growth(GROWTH), Market to book value of equity(MVBV), volatility(VOLATILITY), market value of equity (MVE) and section dummy (SECTION) showed their statistically significant effects on the book-value based leverage ratios, respectively, while size(INSIZE), growth(GROWTH), market value of equity(MVE), beta(BETA) and section dummy (SECTION) showed their statistically significant effects on the market-value based leverage ratios. This study also found an interesting result that a firm belonging to each corresponding industry has a tendency for reversion toward its mean and median leverage ratios over the five-year tested period.

This research aims to figure the different perceptions on the organization-public relationship between military officials and the locals, and the perception on the support military family welfare. In order to analyse their subject point of view, 217 career soldiers and the 191 local residents surveyed during 3 weeks from 10th February to 28th February, 2014. The results getting from this research were as to follows; First of all, the perception on the military organization-public relationship towards local community is more positive in the military officials(M=5.39) than the locals(M=4.99), but different from the two groups(t=6.93, p<.001). Moreover, there exists statistically significant different in every sub-factors and it means the mutual perception consistency is low. Second, the perception on the support from the locals towards military family welfare of military(M=5.38) is higher(t=6.93, p<.001) than the perception of the locals (M=4.76) and it is statistically significant. Third, the a regression coefficient which indicates the impact on the perception on support military family welfare through the change of organization-public relationship shows statistically significant (${\beta}=.82$(p<.001)). As a result, the perception on the military organization-public relationship of the locals has significant prediction power to the perception on the support military family welfare. And when the perception on the military organization-public relationship of the localsis higher, the perception on the support military family welfare has been changed positively.

The purpose of this study was to explore the impact of lifelong educators' core competencies as a mediating effect on adult learners' ability to function. The subject of this study was aimed at adult learners participating in lifelong education programs at lifelong educational institutions located in Gyeonggi Province. and was finally used for a total of 520 additional analyses. The main findings of this study are as follows: first, regarding the correlation between the core competence of lifelong educators and the life ability of adult learners, core competence has a static association with wisdom. In addition, wisdom has a high static association with life expectancy. Second, the core competence and wisdom of lifelong educators were found to have a significant static impact on adult learners' life abilities, accounting for 66.8%. Specifically, the most significant predictors of life's ability were creative problem solving, consideration for others, and acceptance of change, which were lower factors of wisdom. Third, the impact of a lifetime educator's core competence on adult learners is not significant. It was found that core competence has an indirect influence on life capacity through the mediating effect of wisdom, and that wisdom has directly interfaced the relationship between core competence and life ability. Taken together, these results proved that the core competence and wisdom of a lifelong educator are important variables for adult learner's life abilities. Based on this, the core competence of lifelong educators being taught in the field of lifelong education should be enhanced, and the ability of adult learners to utilize the wisdom that has been developed through the experiences of adult learners, to improve their life skills.
