Generating a super-resolution meteological data by using a high-resolution deep neural network can provide precise research and useful real-life services. We propose a new technique of generating improved training data for super-resolution deep neural networks. To generate high-resolution meteorological data with domain specific knowledge, Lambert conformal conic projection and objective analysis were applied based on observation data and ERA5 reanalysis field data of specialized institutions. As a result, temperature and humidity analysis data based on domain specific knowledge showed improved RMSE by up to 42% and 46%, respectively. Next, a super-resolution generative adversarial network (SRGAN) which is one of the aritifial intelligence techniques was used to automate the manual data generation technique using damain specific techniques as described above. Experiments were conducted to generate high-resolution data with 1 km resolution from global model data with 10 km resolution. Finally, the results generated with SRGAN have a higher resoltuion than the global model input data, and showed a similar analysis pattern to the manually generated high-resolution analysis data, but also showed a smooth boundary.

This study is to find the convergence effect of a husband's help on self-efficacy and postpartum depression in mother. Each husband did mother and baby care until postpartum 6th week after completing three sessions of education. The data was collected in the 1st and 6th week postpartum, and analyzed using SPSS 20.0. Husbands's practice rate was 80%. Factors affecting to mothers' self-efficacy were parity, antepartum admission and husband's job, and to their postpartum depression were mothers' education, monthly income and antepartum depression. Prevalence of postpartum depression in the 1st and 6th week were 33.3% and 1.7% each. There were significant differences in increasing self-efficacy and in decreasing postpartum depression(p<.001), and there was a negative correlation between two variables(r=-.62, p=.01). Husbands' help brought convergence effects on increasing mothers' self-efficacy and decreasing postpartum depression(p<.001). This results could be used in developing intervention programs in managing mothers' self-efficacy and postpartum depression after repeated studies with wider range of subjects.

The purpose of this study was to investigate the convergence factors affecting professional identity perceived by the emotional labor of clinical practice and self-esteem in some dental hygiene students. The questionnaire was conducted in 205 dental hygiene students from 3 university in Jeollanam-do area. The data were analyzed using SPSS 12.0. Professional identity correlated positively with self-esteem(r=0.366, p<0.01), negatively with emotional labor of clinical practice(r=-0.213, p<0.01). The convergence factors influencing professional identity were satisfaction level with majors(${\beta}=0.434$), self-esteem(${\beta}=0.236$) and emotional labor of clinical practice(${\beta}=-0.199$). The regression model explained 34.6% of professional identity. Therefore, to enhance professional identity in dental hygiene students, it is required to program development to improve satisfaction level of with majors, self-esteem and management of emotional labor of clinical practice.

This paper tried to analyze cases of one year team-based project of gifted students who spent two year programs in a math-IT integrated class as part of formative evaluation and extracted the factors associated with future enhancement for the program. The researcher as an advisory professor tried to guide the students as minimally as possible considering their levels of IT skills so that they could self-directedly perform the IT-fused project on a team basis. The data collection included documents, annual report, photos, video, artifacts and interview data with the students for the whole team project carried out between February and December, 2015. The overall pattern of the project activities has been stabilized in the middle of the course compared to the initial stages of brainstorming and design work even though the students revealed the differences of their programming skills and preferences toward the project theme. Their project outcomes were qualitatively analyzed according to the 9 steps of R&E model and has shown individual differences according to low, middle and high level. At the end, the analysis suggested several implications for further improvement of the mentorship program.

The Purpose of this study was to convergence factors which affect the subject of basic dental hygienics in some dental hygiene students. The questionnaire was conducted in 450 dental hygiene students who had completed clinical practice. The level of self-confidence of the students was significantly higher if the level of satisfaction with the subject of basic dental hygienics was higher (r=0.365). Also, the level of self-confidence was significantly higher if the satisfaction with the major was higher (r=0.320) and the level of satisfaction with the major was significantly higher if the level of satisfaction with the subject of basic dental hygienics was higher (r=0.314). This study is expected to be used as a basic material for the development of systematic and convergence programs related with basic dental hygiene in connection with clinical practice.

The purpose of this study is to investigate the effects of the convergent mock interview program on college students who are preparing for employment and their effects on program demand, career attitude maturity and job preparation stress. The study subjects were 73 nursing students and pre - 4th grade college students. Data collection was done before and after the application of the program. The collected data were analyzed using the SPSS WIN 23.0 program. The results of the study showed that there was a statistically significant difference between the program demand (t = 7.92, p <.001) and career attitude maturity (t = 3.35, p = .001).but Job stress (t = .98, p = .327) was not found to have any effect Based on these results, we propose to increase the program period and to develop and apply a customized convergence program tailored to the characteristics of the students.
