Purpose - The Korean child welfare services may have different feelings between providers and users. Few studies on the child welfare service quality have been conducted and research on the coorientation model of child welfare services are nonexistent. We compared the perceptions of Korean child welfare service providers and users in this study. It will have many applications in the service quality fields by applying a coorientation model. Research design, data, and methodology - In order to enhance user satisfaction with child welfare services, around 200 samples were carried out both in Busan and Kyungsangnamdo randomly. Seven point Likert scale was used in the questionnaire. Two measurements were made to evaluate the different positions on the part of child welfare service providers and users to assess their mutual orientation. Paired t-test verification was conducted for congruency analysis, and the verification of agreement and accuracy was analyzed by independent t-tests. Results - We empirically examined the differences between the providers and the users stance. The results are as follows. We have verified the statistical significance of the difference in perception between providers and users. We also confirmed a degree of agreement, a degree of congruency, a degree of accuracy and a degree of meta agreement in the study. In the Korean child welfare service quality, the coorientation model of process quality appeared in the form of semi-dissensus, the coorientation model of results quality were shown in the form of ignorances and the coorientation model of physical environment quality were investigated in the form of semi-dissensus. Conclusion - The study concluded that users need to understand more about the providers in order to enhance the coorientation model in process quality and physical environmental quality, and the providers need to persuade the users clearly about the positive factors. To enhance the coorientation model of the result quality, it can be misunderstood by guessing that the other party will positively evaluate it. Therefore, users believe that they need to talk more clearly to the provider about the results of the korean child welfare service quality to reduce misunderstandings and to understand each other about the resulting quality.

This study examines how the patent results of the University Academic-Industrial Cooperation influence technology transfer. Statistical analysis was performed by using 2013 panel data from the Ministry of Education and Science Technology(MEST) National Research Foundation of Korea(NRF) and the results are as follows. The results show that the patent result factors that have a positive effect on the total number of technology transfers are domestic patent application numbers, foreign patent application numbers, future technology(6T) patent application numbers, science technology patent application numbers. The factors that have a positive effect on increasing royalty are the total number of technology transfers. Domestic patent application numbers, future technology(6T) patent application numbers and science technology patent application numbers have a positive effect on patent results. The results implicate that more research and development is needed for more patents to be applied, that the main focus should be on future technology(6T) and science technology fields, and that effort should be directed at planning negotiation strategies for the term of the contract. However, this study is the need to research, including primary research is so patent performance may be limited in having only been considered in future studies of human and material resources and operating system factors that may be presented to the essential elements of the Industry-Academic Cooperation Foundation this raises.

There have been many studies on subject tests for 3D contents using 3D glasses, but there is a limited research for 3D contents using autostereoscopic display. In this study, we investigated to assess usability of electroencephalogram (EEG) as an objective evaluation for 3D contents with different quality using autosteroscopic display, especially for lenticular lens type. The image with optimal quality and the image with distorted quality were separately generated for autostereosopic display with lenticular lens type and displayed sequentially through lenticular lens for 26 subjects. EEG signals of 8 channels from 26 subjects exposed to those images were detected and correlation between EEG signal and the quality of 3D images were statistically evaluated to check differences between optimal and distorted 3D contents. What we found was that there was no statistical significance for a wave vibration, however b wave vibration shows statistically significant between optimal and distorted 3D contents. b wave vibration observed for the distorted 3D image was stronger than that for the optimal 3D image. This results suggest that subjects viewing the distorted 3D contents through lenticular lens experience more discomfort or fatigue than those for the optimum 3D contents, which resulting in the greater b wave activity for those watching the distorted 3D contents. In conclusion, these results confirm that electroencephalogram (EEG) analysis can be used as a tool for objective evaluation of 3D contents using autosteroscopic display with lenticular lens type.

Gabapentin, 1-(aminomethyl) cyclohexaneacetic acid, is a amino acid derivative, and is clinically effective in the treatment of neuropathic pain and partial seizures of epilepsy as a complementary therapy. The purpose of the present study was to evaluate the bioequivalence of two gabapentin tablets, $Neurontin^{R}$ tablet 800 mg (Pfizer Pharmaceuticals Co., Ltd.) and Gabapenin tablet 800 mg (Hanmi Pharm. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The release of gabapentin from the two gabapentin formulations in vitro was tested using KP VIII Apparatus II method with 0.06 M HCI dissolution media. Twenty six healthy male subjects, $23.85{\pm}2.24$ years in age and $69.40{\pm}11.11$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ crossover study was employed. After a single tablet containing 800 mg as gabapentin was orally administered, blood samples were taken at predetermined time intervals and the concentrations of gabapentin in serum were determined using HPLC with fluorescence detector. The dissolution profiles of two formulations were similar in the tested dissolution media. The pharmacokinetic parameters such as $AUC_{t}$, $C_{max}$ and $T_{max}$ were calculated, and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_{t}$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, $Neurontin^{R}$, were 1.28%, 0.63% and 0.62% for $AUC_{t}$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 (e.g., $log0.9097{\sim}log1.1598$ and $log0.8919{\sim}log1.1262$ for $AUC_{t}$ and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Gabapenin tablet 800 mg was bioequivalent to $Neurontin^{R}$ tablet 800 mg.

This study analyzed the causal relationship among factors that influence the purchase intensions for individual pensions which have a growing importance as a financial means after retirement. For this purpose, structural equation modeling based on the survey data (N = 928) was conducted to analyze psychological factors and financial factors comprehensively. According to empirical results of the structural equation, in the case of non-subscribers of individual pensions, potential longevity and coping efficacy influenced the purchase intensions for individual pensions fully mediated by fear and worry about longevity. Trust in insurers and risk tolerance directly influenced the purchase intensions for individual pensions. These show that trust in insurers is the most important factor in purchase intensions for individual pensions. Also, only trust in insurers give a direct impact on individual pensions in the case of individual pension subscribers. Longevity-related emotional side is expected to help in marketing activities that target potential customers signing individual pensions. In addition, trust in insurers has the greatest impact on new and additional subscriptions that represent critical efforts to improve trust in insurers.

This study was conducted to investigate the dietary behavior and health-related lifestyles of high school students according to the living area in Chonbuk province, Self administered questionnaires were collected from 489 students. Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows: The average weight and height of male students in urban and rural area were 173.52cm, 65.26kg; 172.89cm, 64.02kg. The female students were 161.18cm, 52.48kg: 160.96cm, 52.82kg. The breakfast skipping ratio of students urban area were higher than the students in rural area, About 85% of students responded to have a lunch at school foodservice canteens. About 30% of students responded to have a dinner irregularly, which mainly caused by the reasons 'irregularity of life style' and 'weight control'. The ratio of snacks intake of the students were high, but female students eaten more fruits, cookies and coffee than male students. More than 50% of the students responded that one of the important influencing factor for health was 'a good eating habits'. About 44% of students in urban area and 40% of in rural area responded to take exercise one or three times a week. Students in urban area(37.3%) have more experiences of taking nutrient supplements than those in rural area(15.8%). TV/Radio (48.7%), clinic/apothec(19.0%), and family(16.0%) were essential sources of pertinent information about nutrition. The dietary behavior and health related lifestyle between the students in urban and rural area were very similar, but the female students showed more bad dietary behaviors in comparison with the male students. Therefore, they should have a gender oriented nutritional education program to correct their dietary behaviors and health-related lifestyle for health.

This study analyzed the effects of TLO's organization size, expertise, and economic compensation on technology transfer performance using the panel data of Government-Funded Research Institutes in 2013-2016. First, the size of TLO personnel and budget have a positive effect on the technology transfer performance. However, in the case of TLO manpower, the statistical significance of the effect on the number of technology transfers was only 90%, and it did not affect royalty. Second, TLO expertise has a strong impact on technology transfer performance. It shows that the number of professional license holders, such as patent attorney or a technology valuer, has a statistically significant effect on the increase of the technology transfer number and the royalty under the 99% confidence level. However, unlike expected, the size of the Ph.D. did not seem to have any effect on technology transfer performance. Finally, the economic compensation for TLO does not affect both the number of technology transfers and the royalty. It does not seem to work as an appropriate incentive system, because the absolute size of the compensation is too small. The results of the above analysis suggest that it is important to secure expertise in order for the TLO organization to play a substantial role, and it is necessary to improve the economic compensation system to attract TLOs to technology transfer.

This study explores the factors affecting emotional support between aging parents and adult children living in separate households. With a social exchange perspective on intergenerational family relationship as theoretical framework, the effects of aging parents\` demographic characteristics, potential reward resources. and need for care were tested by analyzing data collected from 2.535 persons aged 65 and over in 9,355 sample households of \`National Survey of Living Status and Welfare Needs of the Elders-1998\`. The statistical analysis of 2,205 aging parents with adult children living in seperate households reveals that the aging parents who have potential reward resources are provided more emotional support by their children than the aging parents without resources are. Findings also show that the elders who live in same households with their own children, and need help from other people with instrumental activities of daily living obtain less emotional support from their children living in separate households. The empirical findings of this study support the social exchange perspectives on family ties between aging parents and adult children living in separate households. but only 8.9 per cents of variance in degree of emotional support is explained by the variables included in the model.

This study examined the effect of parental socioeconomic position on the association between birth outcomes and infant mortality in early and late 2000's. Linked Birth and Infant Death data sets from 2001 to 2003 (T1) and from 2006 to 2008 (T2), provided by the Korea National Statistical Office, were used for analysis. Birth outcomes were categorized into four groups: normal term, small-for-gestational age (SGA), large-for-gestational age (LGA) and intrauterine growth retardation (IUGR). Infant death was defined as the death of a live-born child under one year of age; indicators of parental socioeconomic position were limited to parental education and occupation. The results showed that T2 infant mortality hazard ratios of SGA and IUGR have increased compared to T1. Particularly, preterm and low birth weight babies with shorter gestational age and lighter birth weight than T1 have elevated in T2, possibly indicating that population quality might be continuously aggravated. Moreover, the effect of maternal age on infant mortality has disappeared, rather that of parents' socioeconomic position has increased during the periods, which entailed growing disparities in infant mortality by their social class. Further studies should be therefore done to estimate the effect of parental socioeconomic position on the relationship between birth outcomes and infant mortality in the near future.

The NRCS-CN method is generally used to estimate effective rainfalls in a basin. However, since the curve number which plays a critical role in the NRCS-CN method was originally developed for US watersheds, it is limited to be directly applied to other basins outside the United States. Therefore various modifications have been suggested to revise the NRCS-CN for specific watershed condition. This study introduced the weighted average method and the slope-based CN to estimate effective rainfalls available for Korean watersheds and compared with the observed direct runoff. The overall results achieved from this study indicated that the adjusted slope-based CN considerably increases effective rainfalls in general and makes the duration of effective storm longer. Based on the statistical error analysis performed for various modifications of NRCS-CN, the weighted average method with the adjusted slope-based CN has highest precision with the observed direct runoff. In addition, after analyzing the relation between the initial loss estimated from rainfall-runoff observations and the potential maximum retention from GIS-based data, it turns out that the assumption of linear relationship between the initial loss and the potential maximum retention is not available for Korean watersheds.
