  • Global energy consumption is rapidly increasing yearly due to drastic industrial advances, requiring the development of new energy storage devices. For this reason, supercapacitors with fast charge-discharge, long life cycle and high power density is getting attention, and have been considered as one of the potential energy storage systems. In this research, we developed a supercapacitor that consists of amorphous manganese oxide($MnO_2$) electrodes deposited onto carbon cloth substrates using the hydrothermal method. The Fe-doped amorphous $MnO_2$ samples were characterized by X-ray diffraction(XRD), Energy Dispersive X-ray spectroscopy(EDX), as well as scanning electron microscopy(SEM). The electrochemical analysis of the prepared samples were performed using cyclic voltammetry and galvanostatic charge-discharge measurements in 1M $Na_2SO_4$ electrolyte. The test results demonstrate that the supercapacitor based on the Fe-doped amorphous $MnO_2$ electrodes has a specific capacitance as high as 163F/g at 1A/g current density, and good cycling stability of 87.34% capacitance retention up to 1000 cycles.

  • The purposes of this study were to develop work-life balance supportive organizational culture scale(WLB supportive organizational culture) and to verify it's validity. We reviewed comprehensive studies about work-life balance and organizational culture as well as scales related to them. We theoretically extracted some important factors of WLB organizational culture from reviews and then made 38 preliminary questions. 773 married workers in their 30s to 50s were responded to a questionnaire consisted of 38 preliminary questions and 9 variables(work-life balance, quality of life, job satisfaction, turnover etc) for criterion related validity verification. As the results of factor analysis such as EFA and CFA, we could confirm five factors including WLB organizational management, WLB supportive supervisors, empathetic communication with coworkers, coworkers' material support to WLB and accessibility to WLB programs. Second, correlation analyses were performed to investigate the validation of this scale. In result, it was revealed that the WLB supportive organizational culture scale was highly correlated with other family supportive organizational culture measures as well as dependent variables such as work-life balance, quality of life, job satisfaction, turnover. We expect this study contribute to improve the quality of studies about work-life balance and organizational culture.

  • Recently SMEs(small and medium enterprises) in Korea have experienced severe labor shortages. In particular, college graduates avoiding SMEs are widely spotted. According to previous studies, the main causes of the evasion by college graduates are the inferior working environment and low wages. Some studies also state that SME workers experience discrimination. However, most studies have focused only on unemployment issues of the young graduates. In this research, the results of follow-up surveys on the employment status and job conditions of recent college graduates was linked as a panel data, and the performance of the graduates was analyzed. Based on the analysis, we found college graduates who are employed SMEs are likely to have their initial career fixed to the SMEs. Second, the job separation records of the young SME workers does not show positive labor market performances such as upward movements or wage increases, and the process itself turned out to be entailed frequent separation. Third, the inferior wage level at SMEs and the fact that this effect is cumulatively amplified has been a key factor for evading SMEs. Thus, it is difficult to say that the early-stage careers in SMEs are constructive in future career development. On the contrary, the early careers at SMEs result in lower labor market outcomes, and frequent job separation.

  • While Korea has actively discussed the fields of comics and animation, with an aim toward public art and publicity for cultural welfare, research on public cultural content for the underprivileged and their regions is in fact lacking. The Korean government has also tried to improve Korea's cultural welfare, but its benefits have failed to be evenly given to the underprivileged. Therefore, we need to take greater interest in the underprivileged and their regions. Korea should work to correct the unbalance among regions in the field of cultural welfare (cultural differences between the capital area and other regions, and between new towns and old), as well as improve the living environments of isolated areas. For this reason, such a public art project should be conducted from two directions. First, the underprivileged living in poor conditions should be allowed to live in clean and cultural environments. And second, public art, comics, and storytelling through animation should be formed with an eye on urban culture. This project aims to focus on improving "the quality of citizens' lives" through creating the unique characteristics and landscape of the city. It will be presented through the use of public art, which presents the elements of the city with charm and vitality. The two directions stated above are our urgent tasks. Public art, comics, and animation storytelling regarding the history, culture, and natural resources of the region will develop with the affection and pride of the citizens, and public art will help create an environment that allows people to discuss their issues. In addition, it will be cultural environments that will allow all citizens to enjoy beautiful streets and events. This project will be an opportunity to realize cultural democracy by pursuing social values such as publicity, communication, equality, and participation.
