This study analyzed the effect of career preparation behavior of female college graduates on their job satisfaction. The results of this study are as follows: First, the relationship between job satisfaction and career preparation behavior and a regression analysis of job satisfaction were all examined. This study used the original data from the Korea Employment Information Service for '2012 College Graduates' Occupation Route Survey'. The subjects of this study were 1,569 women in the science and engineering fields (649 engineering graduates, and 920 science graduates). The data was analyzed by frequency analysis, independent sample t tests, correlation analysis, and hierarchical multiple regression analysis using SPSS WIN 19.0. As a result, women with 4 years of college have higher job stability and job satisfaction than college students, but the reasons for major selection, university type, college location, and department. The results of this study are as follows. First, the effect of the variables on career satisfaction and job satisfaction was not statistically significant. This suggests that the type of college does not have a significant effect on job satisfaction if the university systematically prepares people for a career and the university suits a person's aptitude.

In previous Cost-of-Illness (COI) studies, the economic impact of lost leisure time of patients has been mostly underexplored. Furthermore, few studies have focused on chronic or severe diseases, thereby inadequately addressing the segment of self-care patients who do not fall into the categories of inpatients or outpatients. In the present study, we used a comprehensive approach to calculate the annual cost of leisure loss, incorporating factors such as employment status, self-care options, and total period of leisure activity disruption. This required analyzing data from various sources, including health and labor statistics, and applying methods to accurately assess the leisure time lost due to food poisoning. The findings showed that the annual cost of leisure loss for South Korean patients with food poisoning is significant, amounting to approximately 784.5 billion KRW (702.8 million USD, USD/KRW : 1128.34). This study revealed that overlooking self-care patients and not accounting for the affected time in addition to treatment time and employment status significantly underestimated these costs. This study highlights the importance of considering a wider range of factors, including self-care, employment status, as well as the entire affected period, in assessing the societal impact of diseases such as food poisoning. These findings provide valuable insights for policymakers and healthcare professionals to understand the broader economic implications of illness and allocate healthcare resources more effectively.

The purpose of this study was to provide basic data to help individuals with disabilities in single-person households maintain a happy life by analyzing how interpersonal skills necessary for community adaptation and self-esteem, which are personal factors, affect life satisfaction. The self-esteem mediation effect was verified with SPSS Process Macro 4.3 using data on 828 single-person households sourced from the seventh wave of the Disability Employment Panel Survey(2022) conducted by the Employment Development Institute of the Korea Disability Employment Service. To examine the effects of interpersonal skills and self-esteem on life satisfaction, a multiple regression analysis was conducted. While it was found that higher self-esteem was associated with higher life satisfaction, interpersonal skills did not have a significant effect on this association. The path from interpersonal skills to life satisfaction via self-esteem was deemed statistically significant, suggesting that self-esteem mediates the relationship between interpersonal skills and life satisfaction. This study emphasizes the importance of interpersonal relationships for the life satisfaction of individuals with disabilities in single-person households in a modern society in which the problem of social isolation experienced by individuals in single-person households is emerging. Furthermore, it provides a direction for these individuals to become the main actors of their own lives.

This paper used individual establishment level data to estimate the effects of government support for the research and development of 'small and medium enterprises'(SMEs). We analyzed, on the establishment level, the degree of technical advancement, strength of private R&D incentives, and the effect on employment levels of firms which participated in the 2010 government R&D support project. The results of this study are as follows. First, the size and frequency of government investment in the R&D of SMEs were both positively correlated with the amount of patent registrations. Furthermore, we found that the amount of patent registrations were positively correlated with the size of the establishments, but the average level of technological advancement for the firms running the research was lower than the average level of technological advancement for the firms merely participating in the project. Second, the government's R&D policy was found to be complementary to private R&D incentives, and a 1% increase in government R&D investment resulted in an inelastic increase (0.193~0.245%) of the firms' post-program R&D spending. Third, we found that R&D support from the government contributed to an increase of employment by the participating firms. Additionally, we found that the impact of R&D support on job creation varied for the firm size and technological characteristics. Therefore, it is important for governments to take into consideration each type of small business, when setting R&D policies.

High-density SiC-AIN solid solutions were fabricated from powder mixtures of $\beta$-SiC and AIN by hot-pressing in the 1870 to $2030^{\circ}C$ temperature range. The reaction of AIN and $\beta$-SiC (3C) powder transformed to the 2 H (wurzite) structure appeared to depend on the temperature and SiC/A1N ratio and seeds present. The crystalline phases consisted of a SiC-rich solid-solution phase and an A1N-rich solid-solution phase. At $2030^{\circ}C$ for 1 h, for a composition of 50 % AIN/50 % SiC with a seeding of $\alpha$-SiC, the complete solid solution could be obtained and the microstructures are equiaxed with a relatively homogeneous grain size of 2 H phases. The variation of the seeding of $\alpha$-SiC in SIC-A1N solid solutions could be attributed to the transformation behaviour and differences in size and shape of the grains, as well as to other factors, such as grain size distributions, compositional inhomogeneity, and structural defects.

The number of patients with immune- mediated dermatitis such as contact dermatitis is increasing year by year. Allergic contact dermatitis is a complex phenomenon that involves resident epidermal cells, fibroblasts, and endothelial cells, as well as invading leukocytes that interact with each other under the control of a network of cytokines and lipid mediators. It is a cell-mediated immune reaction, which occurs after susceptible individuals are exposed to sensitizing chemicals, and characteristic eczematous reaction is seen at the point of contact with an allergen. In this study, we investigated the allergy prevention effects of quercetin on mast cell-mediated allergic inflammation in BALB/c mice. BALB/c mice were sensitized with 40 ${\mu}l$ of 1.5% picryl choloride (PCL) to the left and right ear each. Total serum IgE levels and histamine levels were measured by the sandwich ELISA method using mouse IgE, histamine measuring kit. For histopathological examination, paraffin sections were stained with hematoxylin and eosin(HE) or toluidine blue(TB). Ear swelling responses were much weaker in the high-dose group (100 mg/kg) than the control group (0 mg/kg). The number of mast cells showed a significant decrease in the high-dose group (100 mg/kg) compared to the control group (0 mg/kg). Degranulation of mast cells was also confirmed by Toluidine Blue (TB) staining method. Both total serum IgE and histamine levels were significantly decreased in the high-dose group (100 mg/kg) compared to other groups. These findings suggest a certain relationship between the elevation of IgE, histamine levels and the degranulation of mast cells. These results show that the pharmacological actions of quercetin indicate its potential activity for prevention of allergic inflammatory diseases through the down-regulation of mast cell activation.

To investigate the effects of the addition of Nb and Sn on the recrystallization of Zr- Sn-Nb alloys, both Vickers micro-hardness test and TEP measurement were carried out on cold-worked specimens annealed at various temperatures from $300^{\circ}C$ to 75$0^{\circ}C$. The microstructures of heat treated specimens were analyzed by optical microscope, SEM, and TEM. The study of microhardness and microstructures showed that both recrystallization process and grain growth were retarded as the activation energy was increased by the addition of Nb and Sn. Especially, the addition of Sn was more effective on retarding recrystallization. Precipitates were formed more easily when Nb was added because the solubility of Nb into Zr is lower than that of Sn. However, the recrystallization process was affected more by Sn than Nb because the strain field formed by substitutional Sn repressed the dislocation movement. TEP was increased due to the decrease of electron scattering as recovery and recrystallization were proceeded and saturated when the recrystallization completed. However, when precipitates formed, TEP was increased because the decrease of solute concentration near the precipitates caused the decrease of electron scattering.

Due to the management innovation policy that was introduced to governmentsupported research institutes (GSRI) in 1998, their employment structure has been continuously changing, with the most notable increase of the number of non-standard researchers and the diversification of employment contracts. This paper examines changes in the employment structure of GSRI over the last 20 years in relation to the introduction and operation of the PBS (project base system), which is a main factor that fundamentally changed the employment structure of research institutes. This paper purposes to analyze the current status of non-standard workers in the science and technology research area through interviewing standard and non-standard researchers. Under the PBS as a principle of organizing their research project, the project-managers cannot help but exploit non-standard researchers to process research within a tight budget. This structure of organizing research projects reinforces the increase of the number of non-standard researchers and diversification of non-standard employment relations. In addition, the wage and working conditions of non-standard workers are getting aggravated in this structure. Considering the characteristics of research institutes, precarious status of non-standard researchers will have negative effects on the development of science and technology.
