  • This study contributes to understanding women's labor market behavior by focusing on a particular set of labor force transitions - labor force withdrawal and entry during the period surrounding the first birth of a child. In particular, this study provides a dynamic analyses, using longitudinal data and event history analysis, to conceptualize labor force behaviors in a straightforward way. The main research question addresses which factors increase or decrease the hazard rates of leaving and entering the labor market. This study used piecewise Gompertz model, following the guide of the non-parametric analysis on the hazard rates, which allowed relatively detailed description on the distribution of timing of leave and entry to the labor market as parameters of interest. The results show that preferences and structural variables, as well as economic considerations, are very important factors to explain the labor market behavior of women in the period surrounding childbirth.

  • The highway weaving section is a point where there is a conflict caused by entry and exit vehicles. In order to minimize the impact on the main line, an accumulation line should be installed. The design speed of the collecting part is 50 km/h, but the actual driver does not have proper deceleration according to the design speed. In this study, considering the driving behaviors, the design specification, and the driver 's viewing angle, the appropriate separation distance for safe entry and exit of collecting, connecting, and collecting roads was examined. As a result of the analysis, it is found that a distance of 60m is required from the point where the merging starts. The results of this study are expected to contribute to the improvement of driver safety due to the conflict between entry and exit vehicles when applied to the weaving section where collecting roads are installed.

  • Recently the telemedicine platform firms which have been temporarily permitted since COVID-19 outbreak have increasingly provided online prescription drugs delivery, causing concerns among incumbent providers of medicine, some of whom began to take aggressive actions again them. In this study, using game theoretic market entry - deterrence model, we show that although the incumbent medicine provider can effectively deter entry by the telemedicine platform firms by its preemptive action, accommodation could be a optimal action when telemedicine platform firms already have penetrated the market with their being permitted to do business due to the COVID-19. However, for the incumbent to cooperate for the successful change in the retail market for medicines, policies like placing a ceiling on the maximum number of taking prescriptions by the pharmacists a day in the telemedince platform network, providing favorable exposure of community pharmacists on the telemedicine platform user interface, and allowing community pharmacies to participate as shareholders of the telemedicine platform firms in its initial public opening of capital, are suggested.

  • Recently, following the commercialization and market entry of smart clothes with diverse functions, smart clothes have been changing from technology-centered products to user-centered products. However, the analysis of consumer demand centered on actual commercialized products is lacking. Therefore, this study classified commercialized smart clothes by function and analyzed the demand and requirements of smart clothes according to sports/outdoor clothes consumption behaviors. As a result, consumers were classified according to their sports/outdoor clothes consumption behaviors into an outdoor leading group with high consumption propensity, an outdoor pursuit group with medium consumption propensity, and an outdoor following group with low consumption propensity. Among the commercialized smart clothes, those with a heartbeat measuring function, those with a heating function, and those with a light-emitting function were presented and demand analysis was conducted. According to the results, the outdoor leading group and the outdoor pursuit group had higher levels of awareness, preference, and purchase intentions than the outdoor following group. In addition, the outdoor leading group showed the highest level of purchase price acceptance while the outdoor following group showed the lowest level of purchase price acceptance. However, this study has a limitation that the acceptance for smart clothes were analyzed with consumers who had experience in sports outdoor clothes consumption. Therefore, in future, studies will be conducted with a wide range of consumers.

  • The purpose of this study was to examine the main and interaction effects of day-care experiences and maternal parenting behavior on preschoolers' externalizing and internalizing problem behaviors. A total of 248 preschoolers(112 boys and 136 girls) and their mothers participated in this study. Mothers provided information about their children's day-care experiences(i.e., age of entry, hours per week, days per week, and number of day care centers attended by the preschoolers), their parenting behavior, and their children's problem behavior. Data were analyzed using correlations, multiple and hierarchical regressions, and post-hoc analysis suggested by Aiken and West(1991). First, preschoolers who frequently changed day-care centers showed higher levels of aggression. Second, maternal logical explanation, coercive and neglecting parenting behavior significantly influenced preschoolers' externalizing and internalizing problem behavior. Finally, interactions of day-care experiences and maternal parenting behavior were significant in predicting preschoolers' problem behavior. These findings suggest that day-care experiences need to be considered with other family variables in predicting preschoolers' developmental outcomes.

  • This study explores on the static and dynamic growth patterns of high-tech ventures in Korea. We developed an integrative framework with target market (local vs. global), product/market maturity (existing vs. emerging), and technological capability (follower vs. pioneer). We also identified seven new ventures strategies as follows: i) reactive imitation, ii) proactive localization, iii) import substitution, iv) creative imitation, v) early market-entry, vi) global niche, and vii) global innovation. With five successful Korean new ventures, we found different competitive behaviors and performance among new venture strategic types. This study also observed two different growth patterns: growth through strategic replication and growth through strategic change. It depends on whether they are pursuing similar strategy over time or different strategy within for growth. In addition, we found that creative imitation plays a stepping-stone role in two-step internationalization processes. Although this study is exploratory and needs more empirical studies, it can provide new ventures with meaningful guidelines for growth and internationalization with a dynamic perspective.

  • We developed a new grid-based Monte Carlo code to trace far UV He II line photons that are incident on a thick H I region and subsequently transferred through Rayleigh and Raman scattering with atomic hydrogen. In particular, we consider a neutral region that is moving away from the He II emission source which is either monochromatic or is described by a Gaussian profile. The resultant Raman scattered He II line profiles from a monochromatic source are characterized by a double peaked core part with an extended Raman red tail that is attributed to multiple re-entry events. Complicated behaviors are observed in the case of a Gaussian He II source including the formation of a secondary red peak near the Balmer center dependent on the H I column density. A preliminary application of our results to the CFHT data of the planetary nebula IC 5117 is presented.

  • The Alcoholics Anonymous(AA) program has been known to be effective in many countries in helping alcoholics to stop drinking and to change their attitudes, beliefs, and behaviors. In this study, we examined AA activities among Korean AA members and measured the self-evaluated physical, social, and mental changes following the entry into the AA program. Out of identified 300 AA members who were attending 18 different AA group meetings at the time of the survey, 207 completed the self-administered questionnaire(response rate of 69.0%). T-test and ANOVA were used to compare the scores of physica(4-items), social(4-items), and menta(10-items) changes according to the level of AA activities. The proportion of the respondents who practiced the 11th step (meditation) or the 12th step (take alcoholics to a meeting after carrying messages) on the regular basis was 66.6% and 37.2%, respectively. The average time spent in meditation per week was $4.8{\pm}5.47$ hours. The length of participation in AA meetings has significantly positive impact on the average score of changes in all the 3 health states; physical(p<.01), social(p<.05), and mental states(p<.01). Also, practicing the 11th step was significantly associated with improvement of social(p<.01) and mental(p<.05), while practicing the 12th step improved only mental states(p<.01). Our findings demonstrated that not only the length of participation in AA meetings but also the practice of regular meditation(11th step) and taking alcoholics to an AA meeting after carrying messages(12th step) are very important for AA members, and lead to great positive changes in physical, social, and mental states following entry into the AA program.

  • This study explored the effect of job experience while attending engineering colleges on entry into the labor market. To this end, the relationship between work experience and first job success among the job preparation behaviors of engineering majors and students with other majors was compared. Next, we analyzed the effects of work experience such as internships experienced by engineering students on adjusting to their first job after graduation and maintaining their employment. In particular, by analyzing the relative influence of factors affecting engineering students' entry into the job market, what kind of policy efforts can be made at the university level for the success of engineering students' employment is presented. The results showed that work experience affects the quality of employment of engineering, and it had a positive effect on all engineering students regardless of gender.

  • Unsaturated hydraulic conductivity (HC) is integrated theoretically from soil water retention curves (SWRC) by Mualem capillary model, but the prediction of HC is extremely sensitive to small variation of matric suction near saturation. Near saturation, the Mualem HC based on smooth SWRC decreases abruptly and has problems in the reliability of hydraulic behavior and the stability of numerical solutions. To improve van Genuchten-Mualem (VGM) HC, the van Genuchten SWRC model is modified within range of low matric suction (arbitrary air entry pressure). At an arbitrary air entry pressure, the VG SWRC is linearized in log scale until full saturation. The modified VG SWRC does not affect the fit of actual retention behavior and either the parameters of original VG SWRC fit. Using the modified VG SWRC, the VGM HC is modified to integrate for each interval decomposed by arbitrary air entry pressure. An analytical solution on modified VGM HC is proposed each interval, to protect the rapid change in HC near saturation. For silty soils, VGM models of HC function underestimate the unsaturated permeability characteristics and especially show rapid reduction near saturation. The modified VGM model predicts more accurate HC functions for Korean weathered soils. Furthermore, near saturation, the saturated HC is conserved by the modified VGM model. After 2-D infiltration analysis of an actual slope, the hydraulic behaviors are compared for VGM and the modified models. The prediction by the proposed model conserved the convergence of solutions on various rainfall conditions. However, the solution by VGM model did not converge since the conductivity near saturation reduced abruptly for heavy rainfall condition. Using VGM model, the factor of safety is overestimated in both initial and final stage during heavy rainfall. Stability analysis based on infiltration analysis could simulate the actual slope failure by the proposed model on HC.
