  • Using driving simulation, this study investigated the effects of driver's trust in the adaptive cruise control (ACC) system and road density on driver's workload and situation awareness. The drivers were allocated into one of four experimental conditions manipulated by ACC system trust level (trust-increased vs. trust-decreased) and road congestion (high vs. low). The workload and situational awareness of the participants were measured as dependent variables. The results showed followings. First, trust-decreased group for the ACC system had significantly lower trust scores for the system in all of the measurement items, including reducing the driving load and securing safe driving due to the use of this system, than the trust-increased group. Second, the trust-decreased group showed a slower reaction time in the secondary tasks and higher subjective workload than trust-increased group. Third, in contrast, the situational awareness for the driving situation was significantly higher in the trust-decreased group than trust-increased group. The results of this study showed that the driver's trust in the ACC system can affect the various information processing performed while driving. Also, these results suggest that trust in the user's system should be considered as an important variable in the design of an automated driving assistance system.

  • Recently, in Korea, financial institutions such as banks are most severely affected by the universalization of the Internet and smartphones. On the other hand, the use of online systems by financial institutions keeps increasing; the convenience of online services has a significant influence on the attraction and the retention of financial customers; consumer needs are also diversely expressed. This paper deduces from the precedent researches a mechanism that online financial system enhances the trust of customers -the medium of the online system and other customers- and its perceived easiness affects its perceived effectiveness and then all these internal variables induce satisfaction. Plus, this paper aims at verification of the hypothesis in terms of an extended technology acceptance model, based on the hypothesis that word of mouth and repurchase are significantly linked to this mechanism. Through this study, the researchers tried to check how the online service quality and emotional factors of financial institutions affect the users in accordance with the trend of changes in the service usage method of financial institutions, and confirmed that the hypothesis was not rejected.

  • This study was carried out as a preliminary study to analyze the effect of parenting attitudes on the career decision-making types of middle school students. We analyzed the mediating effect of self-efficacy to develop a program that can be implemented jointly at home and at school to help middle school students who are facing the Free Semester System in 2016 to form an ideal career decision-making type. To that end, a survey was conducted with 345 students attending a middle school located in Northern Seoul, and the 335 valid questionnaires were analyzed using SPSS v22. In the sociodemographic analysis, there was no difference in parenting attitudes between groups in terms of religion and family income. The democratic attitude of parents had the greatest impact on the rational career decision-making type, while the permissive attitude had a partial effect. The authoritarian attitude had no effect. Self-efficacy had a mediating effect in only the relationship between democratic parenting attitude and the rational career decision-making type. These findings imply that to help middle school students form a rational career decision-making type, intervention in variables other than self-efficacy is necessary in addition to parent education.

  • This study was carried out for two purposes. One is to analyse the relationship between export performance and the five capabilities of R&D intensive firms (new product development, overseas market information, SNS and communications, brand and marketing). The second purpose is to verify the difference in those capabilities between R&D intensive small companies and mid-sized companies. Based on the OECD's classification of "technology intensity", R&D intensive firms are defined as the firms which are investing more than 5% of their annual sales in R&D activities. This study reveals the significant and positive relationships between the export performance and three capabilities( overseas market information, SNS and communication, brand) except for new product development capabilities and marketing capabilities. Those capabilities increase export performance. On the other hand, this study finds a significant difference in overseas market information capabilities and brand competence between R & D-intensive SMEs and mid sized companies. It is shown that those two capabilities in the mid sized firms are stronger than in the SMEs. These findings have important implications for the growth of R&D intensive SMEs in the global market. First, for higher export performance of R&D intensive firms, three capabilities such as overseas market information, SNS-communication and brand should be strengtened. In particular, SNS-communication capabilities as innovative marketing competences should be developed together with traditional marketing capabilities. Second, the growth of SMEs into Mid-sized firms needs the development of brand competences and overseas market information capabilities.

  • The purpose of this study is to provide the basic data necessary to improve the planning and operations for an effective on-the-job training (OJT) by analyzing educational effects and deciding on a career for employment (DCE) effects of OJT based on the perceptions of employees from the specialized high school (SHS). The survey was performed with 301 employees who are working in the industrial institutions including the OJT, among the nation's specialized technical high school graduates. 240 questionnaires were analyzed. The major results of this study are as following. First, the effects of OJT are as following. The OJT have educational effects such as the improvement of job ability and adaptability to workplace, refinement of working life, and career guidance. However, the OJT almost don't have educational effects for contents in relation to the majors in SHS. The OJT had basic DCE effects on graduates, and consistently have had them since they graduated from SHS. Second, the difference of OJT effects by employees' background variables is as following. By the gender, the OJT have more educational effects and DCE effects on male than female. By the types of career decision before taking part in the OJT, the OJT has more educational effects and DCE effects on employees with a high degree of career decision. By the working life satisfaction, the higher working life satisfaction, the higher OJT effects. Therefore, the OJT should be operated to make students feel satisfied with the OJT in order to correspond with the purpose of specialized high school - cultivating talent in specific areas.

  • The purpose of this study was to examine the influence of the SOC strategies of college students taking courses related to lifelong educator on their attitude toward the elderly and successful aging in an effort to provide information on how to teach students to take a favorable attitude toward the elderly and acquire knowledge on the right aging. The major findings of the study were as follows: The male students made more use of an arbitrary selection strategy than the female students, and a loss-based selection strategy was more prevailing among the female students. There were no differences in attitude toward the elderly and awareness of successful aging according to gender and the presence or absence of religion. Aging attitude was under the statistically significant positive influence of a compensation strategy, and a loss-based selection strategy had a statistically significant positive impact on awareness of successful aging. Given the findings of the study, a wide variety of programs and contents that are related to lifelong educator and can be of use for college students who make a preparation for successful aging should be developed and provided in consideration of the variables that affect attitude toward the elderly and successful aging.

  • This is a correlational study to investigate the degree of expectation regarding aging, depression and health promotion lifestyle and to identify the factors influencing health promotion lifestyle among health checkup examinee. The subjects of the study were 143 health checkup examinee who visited the M medical center located in G Metropolitan city. Data were collected from July 5 to 21, 2016 using the structured questionnaire of self-report form. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation, and hierarchical regression. As a result, health promoting lifestyle were correlated with expectation regarding aging positively, and with depression negatively. The factors influencing the health promotion lifestyle were education level, perceived health status, time to move to health care facilities, expectation regarding aging, and depression. With controlled general characteristics, the level of health promotion lifestyle was better explained by the addition of the independent variables of expectation regarding aging, and depression, and the explanatory power of the final model was calculated as 27.0%. Therefore, in order to improve health-promoting lifestyle, it is necessary to consider cognitive factors (knowledge, expectation regarding aging) and psychological factor (depression) besides physical approach.

  • As a basic research to investigate geographical variations of diseases, this study analyzes and compares spatial patterns of 24 different diseases in South Korea using prevalence rate data provided by Community Health Survey in 2012. Descriptive statistical analysis, global Moran’s I computation, and disease mapping were conducted to examine spatial associations and patterns of each disease. After the unique spatial patterns and distinctive spatial associations of each disease were observed, we concluded that 12 diseases displayed statistically significant spatial autocorrelation while the other 12 showed no spatial associations. This study suggests that diseases are caused by different risk factors and possess different etiological mechanisms. Furthermore, the study may lay foundation for future studies of geographical variations of disease prevalence in South Korea.

  • This study analyzed whether differences in individual characteristics and parental attachment affect the career maturity of middle school students in grades 1-3 in Asan, South Korea. Individual characteristics included gender, grade, grades, parental education, and economic level, while parental attachment included mutual trust, alienation, and communication. Career maturity included determinism, objectivity, readiness, independence, and assurance. Results showed there were significant differences in gender, grades, and economic level. Only gender differences affected attachment to mothers, with female students exhibiting stronger effects than male students. Grades that both the father and the mother showed differences. The economic level differed only in father's attachment. The effects of parental attachment on career maturity were found to be higher in career maturity with lower father's alienation and higher mother's mutual trust. Career maturity did not affect the assurance variable. Mother's communication affected determinism and mutual trust affected objectivity. Father's mutual trust and mother's communication affected readiness, and father's alienation showed a negative relationship. Mother's mutual trust positively affected independence. These results may be a valuable reference for understanding the behavioral psychology of adolescents and their parents. However, there is a limit to the generalizability of this study.
