Depending on the degree of access to information, social inequalities, especially economic inequalities, can increase. The information gap can lead to an income disparity, leading to an economic disparity. Recently, as we have evolved into a smart environment, our society is in a more complex situation in the digital divide. In the smart environment, unlike the wired Internet based environment based on the existing PC, various media services that are not tied to the transmission means are emerging and the information gap in the smart environment is causing even more serious problems. The purpose of this study is to analyze the correlation between the informatization level and income of the Korean people based on the information gap index and the results of surveys conducted on the general public in Korea. If there is a difference in the level of income depending on the level of access, utilization, and utilization of information by the Korean people, a new approach or change is needed in the policy or strategy for resolving the digital divide of the Korean government.In particular, it should be accompanied by the consideration and concern for the information alienated group and efforts for the continuous support for the solution of the digital divide. The results show that the correlation between the informatization level of the Korean people and the household income is statistically significant (+). In addition, the correlation coefficient trend is positive, suggesting that the government needs various informatization policies to increase the informatization level of the general public in Korea.

A study for service quality is actively done but that for the quality level of the provided service recognized by the service provider for the same service, and for the difference in quality level of service use recognized by the service user is not relatively widely done. Thus, this study analyzed difference between the quality level of the provided service recognized by the service provider and the quality level of service use recognized by the service user, around administrative service as one of cores of the university service, and examined how difference between both service qualities have effect on business the business satisfaction level of the service provider. We measured the service level provided by the individual in charge of the administrative service of the A-university and examined the service quality in business by use of questionnaires. As the result, it was appeared that the quality level of the provided service recognized by the service provider for the same service quality was higher than the quality level of service use recognized by the service user. In addition, it was found that the quality level of the provided service recognized by the service provider had a significant effect on the service provider's business satisfaction level but the quality level of service use recognized by the service user had not effect on the business satisfaction level of the provider.

PURPOSE. In this study, we aimed to evaluate the amount of marginal gap with two different substructure materials using identical margin preparations. MATERIALS AND METHODS. Twenty stainless steel models with a chamfer were prepared with a CNC device. Marginal gap measurements of the galvano copings on these stainless steel models and Co-Cr copings obtained by a laser-sintering method were made with a stereomicroscope device before and after the cementation process and surface properties were evaluated by scanning electron microscopy (SEM). A dependent t-test was used to compare the mean of the two groups for normally distributed data, and two-way variance analysis was used for more than two data sets. Pearson's correlation analysis was also performed to assess relationships between variables. RESULTS. According to the results obtained, the marginal gap in the galvano copings before cementation was measured as, on average, $24.47{\pm}5.82{\mu}m$ before and $35.11{\pm}6.52{\mu}m$ after cementation; in the laser-sintered Co-Cr structure, it was, on average, $60.45{\pm}8.87{\mu}m$ before and $69.33{\pm}9.03{\mu}m$ after cementation. A highly significant difference (P<.001) was found in marginal gap measurements of galvano copings and a significant difference (P<.05) was found in marginal gap measurements of the laser-sintered Co-Cr copings. According to the SEM examination, surface properties of laser sintered Co-Cr copings showed rougher structure than galvano copings. The galvano copings showed a very smooth surface. CONCLUSION. Marginal gaps values of both groups before and after cementation were within the clinically acceptable level. The smallest marginal gaps occurred with the use of galvano copings.

Objectives: The objective of this study is to evaluate the correlates of depression and perception gap of adolescents' Health-Related Quality of Life (HRQOL) between Parents and Children. Methods: Research targets are all students and their parents who are enrolled in from 1st~3rd grade of middle school to $1^{st}$ grade of high school which was selected intentionally. The survey was conducted from May $16^{th}$ to June $9^{th}$ in 2014 by research staffs equipped with structured questionnaire. $PedsQL^{TM}4.0$ Generic Core Scales and Korean form of the Kovacs' Children's Depression Inventory were the main tool for measuring the HRQOL and depression. Data of 985 respondents, both of parents and children, was used for analysis of this study. Results: In terms of gender difference of depression, 5.8% of adolescents, 3.2% of male and 8.5% of female (p<0.001), are shown depression symptom. Depression rate of the low level students of academic achievement was 11.0% which is the lowest rate to compare to 4.3% of middle level and 2.6% of high level students (p<0.001). The case that parents overestimated their children's overall HRQOL is 3.699 times more likely to have depression symptom than the case which is in concurrence between parents and children. Especially the overestimation in social, emotional, and academic area of HRQOL promote depression 3.918 times, 3.371 times, and 2.258 times more than the agreement occurred of each areas. In contrast underestimation in physical area of HRQOL reduce depression 0.266 times less than the agreement occurred of the area. Conclusion: The perception gap of adolescents' HRQOL between parents and children is the most influential factor to adolescents' depression among all variables which was evaluated in this study.

Background: The aim of this study was to examine the resource allocation among the organs and the leaf morphology of Polygonatum humile. The data were collected from June 2014 to May 2015 in a natural P. humile stand of a temperate forest gap. Results: The dry weight of new rhizome ($R_0$) sharply decreased to the time of new shoot sprouting in next year and was constant for 2 ~ 3 years. However, dry weight of root on $R_0$ increased to the end of growth season and, thereafter, decreased slowly along the time elapsed. The correlation coefficients between the rhizome and the leaf sizes were 0.5 for the last year's rhizome ($R_1$) and 0.6 for $R_0$ and were significant at 0.1% level for $R_0$. The increase of one leaf a plant led to increase of the total leaf area, total leaf weight, and stem length. Moreover, the organ sizes' differences between two plants of the one leaf difference were almost significant at 1% level. In 11-leaf plant, the leaf length/width ratio and specific lea area increased to the second, relative leaf area to the fourth and relative leaf dry weight to the fifth, and thereafter, decreased to the last leaf. The differences in the values of these four parameters between two leaves on a stem were almost significant at 5% level. Conclusion: P. humile examined showed the close relationships between the last year's rhizome or this year's one and the shoot system (leaf and stem) sizes. The leaf number a shoot greatly influenced specific leaf area. P. humile's leaf might showed diverse morphology with leaf rank on a stem in a forest gap environment.

It is very important to understand and interpret the meaning of the sigma level correctly through the Six Sigma project. Especially, the confusion over the relation between sigma level from the short-term point of view and defective proportion or DPMO from the long-term point of view may make a big gap between expected results of the Six Sigma project and real results in the field. The one-tail approximation is commonly used to calculate the sigma level both in most literatures introducing Six Sigma and actual cases of the Six Sigma project. Since the one-tail approximation undervalues the sigma level of the fields such as business and service of which the sigma level is generally low, however. there can be misleading results of the explanation of the sigma level and inappropriate project evaluation. This paper describes the relation between sigma level and defective proportion in detail and clears the difference between the one-tail and two-tail approximation.

This study was intended to confirm the perception of the users for the public libraries specialized service through the difference in library service quality according to the availability of specialized services by utilizing 'LibQUAL+' that is a service quality assessment tool. As a results, there is difference in the minimum and perceived levels between libraries that provide assessment result specialized services for service levels and those that did not. And there was no difference in the expected level. The degree of service showed generally higher user perception in the Adequacy Gap and Superiority Gap than libraries that do not offer specialized services. Therefore, the users of public libraries recognize that libraries that offer specialized services are better served than libraries that do not.

More manufacturing companies tend to outsource their logistics functions to logistics service providers to ensure their own competitiveness than before. This paper investigates the differences between customer perceptions and expectations on three key logistics outsourcing decisions. For testing logistics service qualities, a research model which employs a SERVQUAL model was developed and a survey targeting manufacturing companies has been conducted. The average difference of logistics service level between customer perceptions and expectations was derived as 8% from a result of gap analyses. The findings here reveal the level of service quality of Korean logistics service providers as well as suggest core capabilities for them in order for gaining a competitive edge on the competitors and improving their performances.

The high-level radioactive waste (HLW) produced from nuclear power plants is disposed in a rock-mass at a depth of hundreds meters below the ground level. Since HLW is very dangerous to human being, it must be disposed of safely by the engineered barrier system (EBS). The EBS consists of a disposal canister, backfill material, buffer material, and so on. When the components of EBS are installed, gaps inevitably exist not only between the rock-mass and buffer material but also between the canister and buffer material. The gap can reduce water-retarding capacity and heat release efficiency of the buffer material, so it is necessary to investigate properties of gap-filling materials and to analyze gap spacing effect. Furthermore, there has been few researches considering domestic disposal system compared to overseas researches. In this reason, this research derived the peak temperature of the bentonite buffer material considering domestic disposal system based on the numerical analysis. The gap between the canister and buffer material had a minor effect on the peak temperature of the bentonite buffer material, but there was 40% difference of the peak temperature of the bentonite buffer material because of the gap existence between the buffer material and rock mass.

As the importance of strengthening the competency of managers who are in charge of cash collection and disbursement, and preparing for financial statements becomes more visible, this study examined the competency of middle-level managers of accounting department in general hospitals in Korea. Based on the literature, competency was measured by seven components: achievement and action, service, influence, management, cognition, individual effectiveness, and change management. Survey questionnaires included the respondents' perceived importance and performance of each of the seven components of competency. A total of 84 managers from 29 general hospitals responded to the survey between October 2015 and November 2015. Descriptive statistics, mean comparison (t-tests and ANOVAs), and multiple linear regression were conducted. The results of this study are as follows. Overall perceived importance of the competency was 4.16, while the performance was 3.87, and thus, the difference was 0.29. Among the seven components of the competency, cognition and change management had higher scores in terms of difference between the importance and performance. The regression analyses found that female managers had higher perceived importance and performance of competencies in achievement and action, and influence compared to male counterparts. In addition, participants in this study responded that main reasons for the gap between the perceived importance and performance are low compensation, lack of support, lack of knowledge, insufficient technical experience, excessive workload, and regulations. The results of this study can be used when designing capacity building training opportunities for the hospital accounting department. Also, the managers may evaluate themselves and look at the areas where they can narrow the gap between the perceived importance and performance of the competency that is required for today's leading managers.
