Purpose: The purpose of this study was to draw practical implications applicable to the field by analyzing a double-mediator model of social participation and depression in relation to the utilization of Information Communication Technology (ICT) and cognitive function. Methods: The data from the Fifth Living Profiles of Older People Survey in Korea was used, and the sample included 3,925 people, 75 years of age or older. Descriptive statistics, correlation analysis, and the PROCESS macro test were used for verification of the double mediator model. Results: The results were as follows: First, ICT utilization was rated at an average of 1.4 out of 10, social participation at an average of 1.1 out of 7, depression at an average of 3.72 out of 15, and cognitive function at an average of 22.42 out of 30. Second, ICT utilization has a significant effect on cognitive function. Third, the mediating effects of social participation between ICT utilization and cognitive function were significant. Fourth, the mediating effects of depression between ICT utilization and cognitive function were not significant. Fifth, the serial double mediator effects leading to ICT utilization, social participation, depression, and cognitive function were significant. Conclusion: The study discussed the implications of maintaining and protecting cognitive function in the vulnerable elderly through the utilization of ICT.

Purpose: This study examined the effects of case management (CM) for Medicaid on healthcare utilization considering the Medicaid system. Methods: Data were extracted from survey data on "Healthcare utilization and health status of Medicaid beneficiaries" conducted in 2007 and 2008 by the Ministry for Health, Welfare and Family Affairs. This study was designed to compare the effects on healthcare utilization between the CM group and the non-CM group. The subjects were 535 Type I Medicaid beneficiaries who utilized healthcare more than 365 days during 2006. Results: The outpatient days and medication days of the CM group decreased significantly more than those of the non-CM group with the copayment system. There were no significant differences of healthcare utilization between the CM group and the non-CM group with the designated doctor system. Conclusion: CM worked effectively on Medicaid beneficiaries' outpatient healthcare utilization with the copayment system. However, its effects on hospitalization, which is a major cause increasing the total expense, were not observed. Therefore, future studies are needed to develop strategies to reduce hospitalization and Medicaid beneficiaries outpatient healthcare utilization with the designated doctor system.

This study was conducted to examine the effects of dietary cellulose levels on growth, nitrogen utilization, the retention time of diets in the digestive tract, and caecal microflora of 2-month-old Single Comb White Leghorn male chickens fed 3 purified diets that contained 0, 3.5% and 10% cellulose in equal amount of nutrients for 7 days. Body weight gain and nitrogen utilization were significantly higher (p<0.05), while total microflora counts in the caecal contents and retention time of the diet in the digestive tract were significantly lower (p<0.05) in the group fed 3.5% dietary cellulose compared with the group fed 10% dietary cellulose. Body weight gain, nitrogen utilization and retention time of the diet in the digestive tract decreased significantly while the total microflora count in the caecal contents increased significantly in the group fed 10% dietary cellulose compared to the group fed 0% dietary cellulose (p<0.05). Chickens fed 10% dietary cellulose had significantly increased counts of uric acid-degradative bacteria such as Peptococcaceae and Eubacterium, including Peptostreptococcus (p<0.05). The results suggest that cellulose in purified diets is an effective ingredient and the effects on growth, nitrogen utilization, caecal microflora counts and diet retention time in the digestive tract are dependent on the inclusion rate. Positive or negative effects of dietary cellulose are displayed by growth, nitrogen utilization, caecal microflora counts and retention time of the diet in the digestive tract. Positive effects were displayed when the inclusion rate is 3.5% and negative effects were displayed when that is greater than 3.5% of the diet, and the phenomenon is without reference to the age of the chickens.

Accessibility to medical facilities and personnels has been known as one of important determinants of medical care utilization. This study attempted to identify the effects of medical accessibility in terms of geographical distance and occupational opportunity to the medical utilizations. Two-year-experiences of Yonsei University Health Insurance Cooperatives were used as the sources of data. Out patient utilization patterns of 713 members sampled from 4,352 members of Health Insurance Cooperatives were analyzed in order to identify the effects of medical accessibilities. Findings: 1 Average clinic visit rate of Yonsei Health Insurance is 1.66 per person per year. 2. The utilization rates of geographically more accessible group were 33% higher than that of less accessible group. 3. No marked difference in clinic visit rate were observed between medical and non-medical personnel and their family members. 4. Clinic visit rates among occupationally accessible group were slightly higher than those of less accessible. The utilization rate was more sensitively changed by the insurance policy changes in occupationally accessible group.

Knowledge sharing is safe to say that we have already embarked on knowledge-based global economy where knowledge is a decisive factor in global competition for corporations. So in the age of knowledge-based management, it is how we use knowledge that decides success or failure for corporations and the competitiveness of their countries at large as well. We did this research with the help of those who were working in ICT industry including manufacturing, tourism, and others. In this research, we looked into how project participants, organizational characteristic, and relational characteristic affect knowledge sharing and utilization, and what are the factors that have positive effects on corporate success. And all the factors presented in the research are found to have positive effects on the knowledge sharing and utilization. The factors appeared to have positive effects starting with project at first and then on corporate success at large.

The effects of cecectomy on nitrogen utilization and nitrogen excretion were examined in single comb white leghorn (SCWL) cockerels fed a 5% protein diet supplied with urea. The cecectomy tended to increase nitrogen balance and nitrogen utilization and significantly decreased uric acid excretion (p < 0.01). Urea and ammonia excretion tended to be about 60% increased and decreased by cecectomy in SCWL cockerels, respectively, but blood ammonia, urea and uric acid concentrations were not affected. The results are in good agreement with those obtained previously in cecum-ligated chickens. It is concluded that the improvement of nitrogen utilization and decreases in urinary uric acid excretion in cecectomized chickens do not result from the modification of cecal fermentation.

The objective of this study was to investigate the effects of quality grade (QG) on the physicochemical composition and eating quality attributes of pork belly and shoulder butt. Seventy-two growing-finishing crossbred pigs were slaughtered and their carcasses were graded according to the Korean pork carcass grading system. Based on the grading criteria, the carcasses were classified into: QG 1+ (n=23), QG 1 (n=23) and QG 2 (n=26) groups. At 24 h postmortem, belly and shoulder butt cuts were collected from the QG groups and used for analysis of meat quality, flavor compounds and eating quality attributes. Results showed that the variation in fat content among QG was approximately 2% in the both cut types. The QG showed no effects on all the quality traits: cooking loss, pH and color of the belly or shoulder butt (p>0.05). Thirty-five flavor compounds comprising mainly fatty acids oxidation/degradation-derived products (e.g., aldehydes) and only few Maillard reaction-derived products (e.g., sulfur-and nitrogen-containing compounds) were identified. However, the QG showed a minor effect on the flavor profiles in both the belly and shoulder butt. Regarding the sensory quality, no effects of the QG were found on all the eating quality attributes (color, flavor, juiciness, tenderness and acceptability) for both the belly and shoulder butt cuts (p>0.05). Thus, it may be concluded that the current pork carcass grading standards do not reflect the real quality and value of the belly and shoulder butt cuts.

Purpose - In this research, we investigate the relationship between the level of information technology utilization, social capital and knowledge management, organization performance. For information and knowledge management, participants' certain level of information technology utilization is required and connections among participants are necessary for performing and for synergy effects. Research design, data, and methodology - Reflecting on these, we empirically analyze the effects of participant's information technology utilization level and social capital on knowledge management and organization achievement for the case of Incheon International Airport. Questionnaire is distributed to the airport employees and collected 221 samples for analyzing. SPSS and AMOS statistic programs are used for analysis. Factor analysis, Credibility adaptability, path analysis, hypotheses are verified. Results - The study research shows as follow. First, the level of IT utilization does affect social capital but does not affect knowledge management. Second, social capital affects both knowledge management and organization achievement. To investigate more about the relationship between the level of IT utilization and knowledge management, we analyzed the control effects of personal characteristics, and findings are, first, employees with longer time service recognize the importance that the level of IT use and knowledge management affect organization achievement more seriously than employees with shorter time service do. Second, employees with shorter time service and younger employees have relatively lesser social capital and participate in knowledge management passively. Third, higher position employees think that the level of IT utilization affects knowledge management while lower position employees do not. Conclusions - The level of IT utilization affects social capital, and social capital affects knowledge management and organization achievement. These results suggest that the level of IT utilization is very important to both organization and each employee. So providing related training and education opportunities or incentives to induce employees to make efforts for higher level of IT utilization and thus to participate in knowledge management more actively is necessary. The level of IT utilization affects social capital which airport employees lack. The one of study results indicates the importance of social capital and for higher competitiveness of the airport social capital should be increased.

Purpose: The purpose of this study was to investigate the effects of copayments for doctor visits and prescription drugs on health services utilization in the Type I Medicaid beneficiaries in Korea. Method: This study examined data from the 2007 survey on Health Services Use and Health Status of Medicaid Beneficiaries performed by the Ministry for Health Welfare and Family Affairs. To analyze these sample survey data, the SURVEYFREQ, SURVEYMEANS, and SURVEYREG procedures which incorporate the sample design into the analyses were used. Results: Findings of this study indicate that copayments for doctor visits and prescription drugs of Medicaid Type I beneficiaries have cut overall medical costs. However, although results should be interpreted very carefully because of the relatively low $R^2$, copayments have cut more health services utilization of people who need more health services because of their complex diseases and disability. In addition, besides copayment, several factors are affecting differences in health services utilization before and after copayments implementation. Conclusion: These results highlight the need to examine the effects of copayments more thoroughly according to the kinds of disease, the severity of disease, and the level of copayment.
