The purpose of the present study was to determine the mediating effect of social support on the relationship between the work-family conflict and depression of dual-income parents. The subjects were 214 dual-income parents aged 20 years and the data collected online in April 2021 were analyzed using the SPSS/WIN 24.0 statistical program. This study conducted three stages of hierarchical regression analysis to confirm the mediating effect, which showed that work-family conflict had statistically significant effect on social support (β=-.188, p<.01), which was the mediating variable, and depression (β=.539, p<.001), which was the dependent variable. In the third stage, the study confirmed that social support had a partially mediating effect on the relationship between work-family conflict and depression, which was statistically significant in the Sobel test result as well (z=2.468, p=.013). In conclusion, the study confirms the need to establish strategies and arrange social support to solve the emotional problems of dual-income parents.

The purpose of this study was to find a way to improve the stability and quality of urinalysis by checking the changes in the measurement values of representative clinical chemistry test items according to the repeated freezing and thawing before the urine test and the thawing process. All subjects were 10 healthy males, and the freeze and thaw stability test was performed using their urine samples. In the case of micro-albumin and amylase, there was no statistical significance at 37℃ with time, but at 42℃ and 60℃, there was a statistically significant change in the results with time. There were statistically significant changes in BUN, creatinine, uric acid, and glucose. As a result of long-term stability, after 7 days, glucose mutation increased and amylase decreased at 60℃. In the case of glucose and amylase, there was a statistically significant change in the results over time. To obtain accurate test results, accurate standardization of urinalysis including appropriate collection, storage, and storage methods of urine samples is required and systematic study of conditions for securing stability for each biomaterial is required.

The average age of CEOs of the small and medium-sized enterprises(SMEs) in Korea is 58.8, and discussions are actively underway regarding the support towards the succession companies. Government authorities are also operating a system to support the succession companies, and recently global support is also being demanded. In order to have justification over the support for succession companies, the fact that it greatly contributes to the revitalization of the national economy and the regional economy must be acknowledged in advance. This study analyzed the degree of corporate succession revitalization of the national and regional economy through statistical and empirical analysis. With the purpose to secure the reliability of the analysis, the study has referred to the database of the "Integrated Management System for Small Business Recruitment Project" and the Korea Enterprise Data (KED), which can be the most differentiated aspect compared to the existing research of the past. According to the analysis, it shows that the old companies' performance is significantly higher than the general companies in terms of sales, number of employees, assets, and operating profits⋯etc. The management performance of the old companies (which lasted over 30 years) more than doubles the performance of the start-ups (with less than 10 years of experience) in sales, triples the number of employees, doubles the assets, and more than doubles the operating profit. Thus, it is seen that the contribution to the overall economy is significant. Additionally, as a result of the empirical analysis of the relationship between the regional old companies and the regional economic revitalization, the non-metropolitan area shows better performance than the metropolitan area in terms of the number of employees, assets, borrowings, and rent, which entails policy implications of the polarization between the metropolitan and non-metropolitan areas. In other words, it is found that old companies make a significant contribution to revitalizing the local economy, suggesting that further policies regarding corporate succession are required to support the old companies in the future.

This study is a study on 11-story apartments that increase the event of fires in old apartments where building-related laws and regulations are not retroactively applied. As a result of analyzing the risk of installing fire doors in Improvement Scenario 2-4, assuming that fire doors are installed as basic scenario 1 in the existing situation where fire doors are not installed at the entrance of direct stairs. In basic scenario 1, the visible distance to the entrance of the direct staircase due to the spread of smoke was 260 seconds. Improvement scenarios 3 to 4 with fire doors installed open 300 seconds after the fire was recognized, and when the fire doors were installed at the entrance of the direct stairs, the visibility to the entrance of the statistics team was less than 600 seconds. In this case, the visibility was 600 seconds at the time of installation of the fire door, and scenarios 3 to 4 increased 56.6% compared to scenario 1, lowering the risk of evacuation by more than 50%. In order to eliminate the risk of non-installation of direct statistical groups that increase the risk of smoke spread, building-related laws such as the Fire Fighting Act shall be retroactively applied when installing a direct stairway entrance or balcony folding evacuation system. The improvement caused by the installation of fire doors has numerically proven the necessity of fire doors during evacuation, and the importance of maintaining fire doors can be grasped.

The research method established the hypothesis of the study under the foundation of prior research and developed the survey. The subjects of the study were distributed, retrieved, and analyzed the survey of 163 rice farmers in Buyeo-gun, Chungcheongnam-do. The empirical analysis results show that: First, hypothesis 1 of the brand awareness and image that "rice brand assets will be a positive relationship to trust" were statistically adopted. In particular, statistical t values showed a difference in consumer confidence over recognition>images. Second, hypothesis 2 of the trust of agricultural rice brands will be a positive influence on attachment and loyalty' statistically supported. In this regard, brand trust was higher in loyalty than attachment. Third, the attachment of agricultural products to rice brands will be a positive influence on loyalty,' was statistically supported. The strategic implications of this study are as follows. First, consumers should be given clues of trust(ex, GAP of Natioanl Approval Licesing, Fam Tour) as they distrust the perceived quality of the rice in the market. Second, the effect of the origin of rice is questionable, so the spread of the production power system should prevent the mixing of rice varieties, that is the spread of the production history systems.

The purpose of this study is to identify the factors influencing the user's continuous usage intention of computer games. A research model was developed which shows that the independent variables of value, expectation confirmation, perceived enjoyment affect user satisfaction and continuous usage intention. To test the six hypotheses, survey data were collected from 104 respondents, and hypotheses tests as well as a confirmatory factor analysis were conducted using a partial least square analysis tool. The statistical analysis result showed that expectation confirmation had a significant positive effect on satisfaction, and satisfaction also had a strong positive effect on the game user's continuous usage intention. Perceived enjoyment showed a highly strong positive effect on satisfaction. In addition, satisfaction was found to have full mediation effects in the relationship between expectation confirmation and continuous usage intention, and perceived enjoyment and continuous usage intention respectively. This result provides an important implication that continuous usage intention occurs through user satisfaction, and also indicates the contribution of this study for the game industry. Another contribution of this study is to introduce critical independent variables from the marketing and information technology domains in order to explain continuous usage intention of computer games.
