The purpose of this study is to analyze the relations of innovation and productivity following the introduction of ICT and the effects in the process of innovative investments activity-innovation-productivity, not only by finding causes and effects. For this purpose we conducted surveys of SMEs classified into 7 categories by type of business. To put it concretely, this study was performed to find out the foactors which allow companies to secure competitiveness by enhancing of innovative measures through ICT, and to further analyze the political implications for the development of small and medium-size business by conducting an empirical analysis of the process, from the determination of innovative investments all the way through to production. Analysis model used CDM model using econometric methods such as multiple regression analysis and multinominal logit analysis to produce results. Also we established and analyzed models of innovation investment determinants, innovation determinants and productivity determinants to analyze specifically the relations between ICT and productivity.

The assignment of exploration on individuals provides challenging work environments, while it generates high levels of complexity. On the other hand, the assignment of exploitation on individuals offers less challenging work environments, while it makes low levels of complexity. Give the characteristics of exploration and exploitation, I argue that the assignments of both exploration and exploitation create the favorable work environments to individuals. Developed hypotheses were tested using a logit regression from a sample of 168 project managers in a R&D center. I found that a manager who experienced exploitation project(s) is positively related to higher performance in exploitation project(s). In addition, a manager who experienced both exploitation and exploration projects are found to be positively associated with higher project performance.

This study aims to identify factors that affect the quality of life of rural residents. Data were collected from 4,000 rural residents living in rural areas. Raw data was procured from the 'Survey on Rural Well-being in 2022 in Rural Development Administration'. The main results of the ordinal logit regression analysis are as follows. First, in the case of non-farm households, female, immigrants, more educated, more healthy are more likely to be highly perceived quality of life. In the case of full-time farm households, more healthy are more likely to be highly perceived quality of life. In the case of part-time farm households, younger, married, more healthy are more likely to be highly perceived quality of life. Second, for all rural housholds(non-farmers, full-time farmers, and part-time farmers), local amenities and safety also had positive impact on perception of quality of life.

This paper investigates the determinants for the controlling power and the concentration of the subcontracting trade between the downstream producer and the upstream supplier using a survey data for the IT industry in Gyeonggi-Do. The estimation results of the ordered logit and least square analyses are as follows. First, a firm. s controlling power across the downstream producer and the upstream supplier in the subcontracting trade would grow bigger when the company is bigger, more manufacture-oriented, and has higher ratio of export in sales. Second, the analysis for the upstream suppliers indicates that the higher dependent ratio of the subcontracting trade in the sales, the lower the concentration ratio of the R&D in the sales. Lastly, the analysis of the downstream producers indicates that the higher the dependent ratio of the subcontracting trade in the sales, the higher the concentration ratio of the R&D in the sales, which is distinctively contrast with the analysis result of the upstream suppliers. The overall estimation results are, hence, unsupporting to the transaction cost theory which predicts the increase of R&D investments in both downstream producer and upstream supplier.

Prior studies concerning the analysis of parents' homeownership on its offspring usually focus on the transmission of tenure between two generations. This study adopted a more comprehensive approach on this topic so the effects of parents' homeownership were analyzed through the economic performance of their sons. Korean labor panel data were used to test hypotheses on intergenerational transmission of parents' homeownership. The period covered years 2000 to 2014, consisting of about 862 samples, while many socioeconomic variables were selected through a filtering process. The results of the three hypotheses showed the following consequences. First, parents' homeownership was a meaningful factor in determining their son's housing tenure. Second, parents who are homeowners tended to have more educated sons. Third, parents' homeownership did not affect their son's annual income. This study showed more extensive effects of homeownership, and government strategy must consider this additional benefit in homeownership policies.

To determine the relationship between hypertension and nutrient intake cross-sectional study were performed in a rural area. Adult resident over 30-year-old age were measured blood pressure and body mass index(BMI), and interviewed about food in-take for the previous 24 hours. 250 men and 297 women participated the survey. Significant correlation was showen in men between mean systolic blood pressure and protein density. Significant correlation with mean diastolic blood pressure was showen on protein density, protein energy(%), calcium density and energy-adjusted protein in men. We analysed risk factor for hypertension adjust the effect of age, BMI, sex and family history by multiple logistic regression. Protein density(odds ratio=3.18), fat density(odds ratio=1.94) and energy-adjusted protein(odds ratio=1.01) intake were positively associated with hypertension but sodium density(odds ratio=0.73) was showen to have inverse relationship.

Wornen's lahor market participation as well as the policy concern for wider utilization of married women, have continuously grown up. However, research efforts on the determinants of women's labor market participation, in the context of the relationship hetween life courses and active entry into lahor market, has been far behind the growing interest in this field. This study has conducted an event histoiry analysis of women's labor market transition utilizing personal occupational history data collected by the Korea Institute for Women's Development in 1991. The analysis is divided into tow parts: First part introduces logit regression to analyze the determinants of women's labor market participation and exit. The second part employs Cox regression to see the variation of transition rate between employment and non-employment. The result shows that there is a wide variation in women's labor market participation according to age, cohort, and family formation. Special note is needed for the significantly negative effect of marriage and child birth on labor market participation. The transition pattern of lower class women with less education fits well to the prediction of neo-classical economics; but the tendency of highly educated women's regression to non-employment reveals the strong influence of the unfavorable labor market structure, which can be better explained by the neo-structuralist perspective. There is a strong trade-off between productive and reproductive labor of women, which can only be corrected by strong policy implementation, such as extended child care facilities, abolition of discriminatory employment practices, and expansion of flexible part-time employment.

The purpose of this study is to empirically analyze the effect of information related to the largest shareholder's change on the likelihood of reporting a loss for firms listed on the Korea Exchange. Specifically, this study conducts a logit regression analysis to examine the firm's loss reporting with frequent changes in the largest shareholder among the largest shareholder change types. So, it controls the impact of a firm's loss reporting, such as the previous year's loss reporting and discretionary accruals. As a result of the analysis, firms whose largest shareholder have changed more than 2 times in the accounting period are found to have higher firm risk in loss reporting than other firms. The results of this analysis confirm that frequent changes in the largest shareholder, which are disclosures of investment risks on the Korea Exchange, may result in investment risk situations such as loss reporting.

Although concerns about the opinion shopping have been continuously raised in the audit market, there has been little research on empirical evidence on the existence of audit opinions. For this reason, this study empirically confirmed whether the opinion shopping exists. At first, we measured thresholds of audit opinion issuing of two groups(changed or not-changed auditors). After that, the difference analysis was conducted to verify whether the thresholds of the audit opinion issuing was significant difference between two groups. As a result of the study, there was no significant difference in the thresholds of audit opinion issuing between two groups. This result can be interpreted that the audit opinion shopping is not a general phenomenon in the external audit market. The contribution of this study is to empirically confirmed that audit opinion shopping does not exist in the external audit market.

The purpose of this study was to investigate the effects of human, social and cultural capital and ecological variables on volunteering among older adults. In this study, three variables of education, income and physical health were examined as human capital factors, two variables of formal and informal interaction as social capital factors, three variables of religion, cultural organization participation and quality of life as cultural capital factors, and three variables of existence of spouse, housing tenure and residence area as ecological factors. In addition, two variables of volunteering participation and continuous volunteering participation intention were considered as dependent variables. For this study, "Senior Job Replacement Project Participants" data collected by the Korea Labor Force Development Institute for the Aged were used and analyzed employing logistic regression analysis technique. This study found that three human capital variables(education, income, physical health) had positive effects on volunteering participation and continuous participation intention among older adults; of the two social capital variables, informal interaction had a positive effect on both volunteering participation and continuous participation intention, whereas formal interaction had a positive effect only on continuous participation intention; three cultural capital variables(religion, cultural organization participation, quality of life) had positive effects on both volunteering participation and continuous participation intention; and of three ecological variables, housing tenure and residence area had positive effects on volunteering participation and continuous participation intention, whereas existence of spouse had no significant effects on dependent variables.
