This study is intended to present effective career guidance and direction by identifying the various factors involved in the career preparation behavior for the improvement of the employment rate of culinary and foodservice management major field students. This study was established on the hypothesis of a structural relationship that career decision-making self-efficacy develops career maturity and career preparation behavior on the basis of social cognitive career theory, which was verified through empirical analysis. Out of 450 survey responses from by Culinary and Foodservice Management Major Students, a total of 302 questionnaires were used for the final analysis due to missing values and biased responses(response rate: 83.6%). Collected data were identified using SPSS 16.0 and AMOS 5.0. A higher-order factor model was employed (High-order model) before a confirmatory factor analysis, and this study examined its reliability and validity analysis for hypothesis testing. Career decision-making self-efficacy had positive effects on career maturity(t=6.86, p<0.001) and career preparation behavior(t=3.83, p<0.001), and career maturity had positive effects on career preparation behavior (t=2.79, p<0.01). As a result, all hypotheses were accepted. These results confirmed that strengthening students' faith in themselves with competencies is core competencies with career-related issue can be the driving force that can enable students to develop into mature professionals. Therefore, this study suggests an awareness of the importance of career decision-making self efficacy and proposes a need for a systematic and integrated career counseling program that can improve it.

Under the hypothesis that the form of road network could affect crime occurrence, this study demonstrates to prove them using Space Syntax with real crime data. We calculated integration, control, connection index by means of Space Syntax and analyzed the relationship between the three indexes and the number of crime occurrence on the each road. Next, in order to generalize the analysis results we adopted Multi-Agent Model and simulated several scenarios on the computer virtual space. The results revealed that integration index has the strongest relationship with crime occurrence both in the case of real study area and virtual space simulations. Though this study has several limitations on the extent of virtual space and realistic computer programming of agents' behavior, the results are meaningful to verify the relationship between the form of read network and crime occurrence. Moreover the simulation platform that this study developed has promising possibilities to find realistic solutions on the effective police deployment or facility layout to improve smart safe city development.

This study examined whether the efforts of department store for recovering services may be perceived fairly from the standpoint of customers upon any occurrence of service failure, whether such perceived justice contributes to higher customer satisfaction and trust, and whether such customer satisfaction and trust have positive influence on store loyalty of customers, respectively. For this sake, this study investigated relevant literatures, set up some hypotheses to solve main questionable considerations and made a corresponding empirical analysis. For empirical analysis, a questionnaire survey was applied to total 204 customers who experienced in service recovery around domestic major department stores in the last one(1) year. With regard to empirical analysis to verify some hypotheses hereof, this study verified the reliability and validity of each questionnaire item by means of statistical programs like SPSS 10,0 and AMOS 4.0, followed by verifying hypotheses through SEM(structural equation modeling) analysis. These results indicate that positive efforts of department stores for service recovery upon their service failure may bring customer satisfaction and trust in department store, which result in boosting up store loyalty of customers. In this empirical study, it was notably demonstrated that despite any occurrence of service failure, the corresponding efforts of department stores to improve the level of justice perceived by customers in course of service recovery, had positive effects on better customer satisfaction, trust and store loyalty, and these effects induced customer's continuous repurchase, positive WOM(word of mouth) and recommendation about the use of appropriate department store, which may contribute to better its competitive edge.

Considering the network externality and spill-over effects, this paper constructs the theoretical model for analyzing the financial policies focusing on the credit guarantee system for Creative Economy, which has been set as the new policy paradigm for the Korean Economy. The analytical results show that it is as much as important to improve the efficiency of the financial markets and construct the infrastructure for reducing the information asymmetry problem which would be more serious in the creative finance. Although it is important to fill the gap due to the market failure it is also crucial to construct the appropriate financial schemes for the various stages of the innovative firms growth. Without these, the impacts of current public funding policies may crowd out the amount of private market funds for the innovative firms or reduce the possibility of commercialization of new technologies in these firms. Based on the evaluation of current related public policies from the perspectives of creative finance, we imply that the current financial policies appear to be quantity oriented not the quality based. Although the policy goals would be appropriately set for vitalizing the Creative Economy in Korea, they appear to be still unsuccessful to address the information asymmetry issue which is the major concern in vitalizing the creative economy. Thus we emphasize the market friendly policies, risk-sharing between the various market participants, revitalizing the relationship banking and efficient management of credit guarantee system in Korea based on the analytical model as well as the evaluation of related policies regarding the creative economy.

This study analyzes the effectiveness of government supported R&D program for SMEs by measuring TFP improvements. We estimate TFP for Korean companies from 2011 to 2018 using Levinsohn and Petrin (2003) method which reduces endogenous problem. Then government R&D beneficiary companies were extracted from the NTIS and linked to TFP estimates. The empirical results are as follows. First, as a result of estimating production function, the contribution of TFP to value-added is more important than in the past. Second, the TFP gap between large firms and SMEs continues to wide and there is no sign of easing.(from 3.72 times in 2011 to 5.23 times in 2018). Third, SMEs beneficiaries show higher TFP level than non-beneficiaries. However their TFP was on the decline until government support. After government supported R&D program, it reverses upward. Fourth, although one-year TFP improvement of beneficiaries is bigger than non-beneficiaries, it is smaller than the control group through PSME. Because SMEs participating in government R&D programs had showed downward trend of TFP until R&D program, it is necessary to examine whether there is a fundamental discordance between the demand of SMEs for R&D program and governments policy goal. More sophisticated program design will be required to escape the recognition that government R&D programs for SMEs are just charity.

The study suggested plans to solve the problems of unsold apartments that lead to social and economic issues in our society, analyzed the characteristic factors related to the unsold apartment residents, investigated the preference factors, and finally determined the influence structure between the characteristic factors of residents and the mitigation factor of unsold apartment, for the repurchase intention. From previous studies, this study determined the characteristic factors based on the physical, environmental, social and economic characteristics to make up the characteristic factors for the unsold apartment residents. Then, through a Focus Group Interview (FGI) among the members of a real estate specialist group, it summarized the suitable factors for analysis and analyzed the influence structure between all factors through Partial Least Squares Structural Equation Modeling (PLS-SEM). The study results show that the mitigation factors are the most profound cause of the decision-making for unsold apartment residents, followed by economic factors and residential factors. In addition, the residential satisfaction for the unsold apartment residents has a positive relation with the repurchase intention.

A scaled version of a roller rig is developed to demonstrate the dynamic characteristics of a railway vehicle for academic purposes. This rig is designed based on Jaschinski's similarity law. It is scaled to 1/10 of actual size and allows 9-DOF motion to examine the up and down vibration of a train set. The test rig consists of three sub-hardware components: (i) a driving roller mechanism with a three-phase AC motor and an inverter, (ii) a bogie structure with first and second suspensions, and (iii) the vehicle body. The motor of the rig is capable of 3,600rpm, allowing the test to simulate a vehicle up to a maximum speed of 400Km/hr. Because bearings and joints are properly connected to the sub-structures, various motion analyses, such as a lateral, pitching, and yawing motion, are allowed. The slip motion between the rail and the wheel set is also monitored by several sensors mounted in the rig. After the construction of the hardware, an experiment is conducted to obtain the natural frequencies of the dynamic behavior of the specimen. First, the test rig is run and data are collected from six sets of accelerometers. Then, a numerical analysis of the model based on the ADAMS program is derived. Finally, the measurement data of the first three fundamental frequencies are compared to the analytical result and the validation of the test rig is conducted. The results show that the developed roller rig provides good accuracy in simulating the dynamic behavior of the vehicle motion. Although the roller rig designed in this paper is intended for academia, it can easily be implemented as part of a dynamic experiment of a bogie and a vehicle body for a high-speed train as part of the research efforts in this area.

The finite element method (FEM), a powerful numerical modeling tool for solving various engineering problems, is frequently applied to three-dimensional (3-D) modeling thanks to its capability of discretizing and simulating the shape of model with finite number of elements. Considering the accuracy of the solution and computing time in modeling of engineering problems, it is preferable to construct physical continuity and simplify mesh system. Although there exist systematic mesh generation systems for arbitrary shaped model, it is hard to model a simple cylinder in terms of 3-D coordinate system especially in the vicinity of the central axis. In this study I adopt cylindrical coordinate system for modeling the 3-D model space and define the origin of the coordinates with mathematically clear coordinate transformation. Since we can simulate the whole space with hexahedral elements, the cylindrical coordinate system is effective in handling the 3-D model structure. The 3-D do resistivity modeling scheme developed in this study provides basie principle for borehole-to-surface resistivity survey, which can be a useful tool for the application to environmental problem.

This study is to explore how TV drama describes divorce process by the reason of extramarital relationship in the drama. To explore this subject, 30 drama synopses delineating extramarital relationship were analyzed. The results revealed that most of the couples had difficulties in emotional relationship and communication. The couples relationship was described traditionally patriarchal: husbands showed their authorities and wives showed dependency on their husbands. The partners of extramarital relationship were the lovers before current marriage. The patterns of extramarital relationship included 'intention to look for vitality despite satisfying current marriage' for the husbands and 'intention to avoid dissatisfied current marriage temporally' or 'to maintain marriage despite dissatisfaction' for the wives. For those who married 6 years and longer, more extramarital relationship was accepted as a terminator of the marriage. And in many cases, the divorce dose not mean to maintain the relationship with extramarital partner but to collapse of trust in partner. The results imply that the social work needs to be more sensitive to middle-class couples' communication and relationship problems. This will lead to the development of the social work intervention program for the couples.

Startup teams should be prompt to seize an business opportunity and handle various business problems with which they has not been faced before. This research examines and compares the hypotheses about the processes of communication media usage, knowledge sharing and team agility by the level of task conflict. In order for detailed investigation, each of antecedent was divided into sub-dimensions: communication media usage into synchronous and asynchronous media usage, and knowledge sharing into speed and quantity of knowledge sharing. Team agility, the dependent variable, was proposed as an important success factor of startup teams. The research model describes that the communication media usage affects knowledge sharing and consequently team agility. The differences of media usage and relationships among variables were proposed as the level of task conflict in teams. 230 data points were collected from startup teams under 5 years and statistically processed to test research model and hypotheses. From the total sample analysis, the results indicate that the knowledge sharing speed is positively associated with the quantity, and the knowledge sharing speed and quantity have positive associations with team agility. Both synchronous and asynchronous communication media usage also has significant positive associations with knowledge sharing speed. On the other hand, media usage did not show significant direct association with knowledge sharing quantity. From the group comparisons of task conflict, it was found that the higher task conflict, the higher in media usage, knowledge sharing speed and quantity, and team agility. The process of media usage, knowledge sharing, and team agility were found to be different between the high and low task conflict. From these results, the authors discussed and proposed some implications for startup team leaders.
