This study aims to investigate how adolescents' expectation of their future according to their self-esteem and perceived social support from parents, teachers, and peers. The study surveyed 611 adolescents, who live in Jeju. The data was analyzed by t-test, ANOVA, and step-wise Regression analysis. The main results of the study were as follows. First, the adolescents generally had a positive perception of their future. Second, there were significant differences in their perceptions of expectancy for the future according to school grade, leadership experience in school, experience with voluntary activities, educational background of the father, educational background of the mother, level of living, self-esteem, parent support, teacher support, and peer support. The parents with a higher educational background tended to have a professional career, have high expectation for their children, serve as role models for their children, and have a high level of positive perceptions of the future. Finally, the variables which affect the adolescents' expectancy for future were examined hierarchically by a step-wise regression analysis. As a result, in general, level of living, self-esteem, and social support were the most important variables, and self-esteem and parent support have the greatest impact on their perceptions of expectancy for the future.

This paper introduces a video based traffic monitoring system for detecting vehicles and obstacles on the road. To segment moving objects from image sequence, we adopt the background subtraction algorithm based on the local binary patterns (LBP). Recently, LBP based texture analysis techniques are becoming popular tools for various machine vision applications such as face recognition, object classification and so on. In this paper, we adopt an extension of LBP, called the Diagonal LBP (DLBP), to handle the background subtraction problem arise in vision-based autonomous parking systems. It reduces the code length of LBP by half and improves the computation complexity drastically. An edge based shadow removal and blob merging procedure are also applied to the foreground blobs, and a pose estimation technique is utilized for calculating the position and heading angle of the moving object precisely. Experimental results revealed that our system works well for real-time vehicle localization and tracking applications.

Objectives: The purpose of this study was to evaluate the perception of dental hygienists and look for ways to inform the dental hygienist correctly by investigating factors influencing the perception of dentalhygienists. Methods: The final analysis population for this study was composed of 302 adults aged 20 years or older who were living in Seoul or Gyeonggi-do. Statistical analysis of the collected data was conducted using the SPSS WIN 22.0 statistical program. Results: When factors influencing perceptions of dental hygienists were investigated, educational background beyond high school (p<0.05), educational background beyond college (p<0.001), occupation (student, p<0.05), title (dental hygienist, p<0.01), and whether dental hygienists offered comfort during treatment (yes, p<0.001) were found to exert statistically significant influence. In other words, participants with educational background beyond high school and college, student, participants who call the title dental hygienists, and participants who felt comforted by dental hygienists during treatment had better perceptions of dental hygienists. Conclusions: Based upon the results as mentioned above, It will be needed more training to enhance the skills of a dental hygienist patient response. Also participants who felt comforted by dental hygienists during treatment had better perceptions of dental hygienists. This indicates a need to devise ways to better foster the ability of dental hygienists.

Retro fashion is emerging among young people as an approach to discovering a new meaning in Korea's historical culture. Research on Korea's unique retro fashion culture is required because there is no research on retro fashion culture based on Korea's historical background. Therefore, this study examined how retro fashion culture has progressed based on Korea's historical background from a nostalgic perspective. All retro-related newspaper articles from 1950 to 2020 were collected, and content analysis was conducted for each semantic unit. The results revealed that personal nostalgia is based on personal experience and is extending to younger generations. In terms of nostalgia in interpersonal relationships, the younger generation reinterpreted the fashion culture of the older generation after the 2010s. In terms of vicarious nostalgia, a retro culture reminiscent of the 1990s with a background in economic development and consumption culture appeared after 2012. The youth culture and university culture of the 1970s and 1980s were reinterpreted as street fashion. Since the late 2010s, the younger generation has been exhibiting cultural nostalgia, believing that the historical Korean culture is not outdated but has a unique heritage formed during the modernization process. Symbolic nostalgia appeared in Korean fashion culture during modernization.

The concentrations of organic carbon (OC) and elemental carbon (EC) in fine aerosols were determined from the samples collected at the two background sites of Kosan in Cheju Island and Kangwha. Samplings were carried out during the spring and winter of 1996 and the fall and winter of 1997. PM25 particles were collected on the prefired quartz filters for 24 hours and analyzed by the selective thermal oxidation method. The concentrations of OC at the sites were higher than those commonly observed from clean areas around the world, but those of EC at both sites were lower than, or comparable to, other clean areas in the world. Both the OC and EC levels at Kangwha were higher than those at Kosan. According to backward trajectory analysis, most air pollutants collected at the two sites were from China. It was found that the OC and EC concentrations in air masses from southern China were higher than those from northern China.

The mission of SSTF is test of superconducting cables for KSTAR magnets. To make realistic environment for superconductor in SSTF, background magnets are required. Cable-in-conduit conductors (CICC) are widely used for large scale superconducting magnets such as ITER and KSTAR. Main design criteria for conductor of superconducting magnets are stability, operating margin and cable cooling requirement, caused by peak field and the gradient of fields with respect to time, in system. ZERODEE which used energy balance method, is applied for the calculation of stability. To increase conductor performance, three different strands, such as HP-I, HP-II, and HP-III, are tested. The present configuration of CICC is used for main coils of background magnet in SSTF and Central Solenoid coils of KSTAR magnets.
