  • The aim of this article was to review various methods used to evaluate the accuracy of digital dental models. When evaluating the accuracy of digital models, the errors can be reduced by educating examiners and using artificial landmarks. The accuracy evaluation methods of digital dental models are divided into linear measurement, 2-dimensional cross-sectional analysis, and 3-dimensional best fit measurement. As the technology of scanners develops, many studies have been conducted to compare the accuracy of digital impression and conventional impression. According to improvement of scan technologies and development of 3-dimensional model analysis software, the ability to evaluate the accuracy of digital models is becoming more efficient. In this article, we describe the methods for evaluating the accuracy of a digital model and investigate effective accuracy analysis methods for each situation.

  • Recently, the property damage has been increasing due to climate change in South Korea. While the general public has become more aware of the environmental issues, but the environmental education system has not been able to meet up with the demands of the public. The purpose of this study is to suggest preliminary data which is needed for developing a environmental textbook. A survey was conducted to meet the following requirements. Respondent's level of interest in problems or situations concerning the following eight themes: fundamental science, health and medicine, aerospace engineering, life science, electrical electronics, telecommunication, mineral and energy resources, environment. The data was collected from 139 students in Seoul and Gyeonggi province. The results showed that health and medicine issues interest students the most (49.6%), followed by environment (46.8%). We asked the respondents who were very interested in each question for their reasons, and they answered that environmental issue is related to the improvement of their life quality (53.8%) than their curiosity (38.5%). Students were very interested in the other issues because of just curiosity. Most students (90.6%) said seasonal change was not same each year. 18.0% of respondents replied that they and their friends had experienced climate change. The majority of students (94.2%) thought that they will experience natural disaster blamed on climate change during their life. In other words, climate change is already the day-to-day events of their lives. The majority of their opinions, more then three than ten students(30.9%) said the South Korean government should conduct an energy saving campaign to climate change problems followed by expanding new renewable energy (24.5%), conducting adaptation policies of climate change(22.3 %), introducing of a system as like $CO_2$ emissions trading(20.9%) and so on. There are more Stu- dents (69.1%) who know of new renewable energy than students who don't know it; however, respondents who know the meaning very well were just 18.7% showing that most students dimly know the meaning of new renewable energy.

  • The purpose of this study is to analyze an experience of field practice perceived by vocational teachers. Data for analysis were collected from 689 vocational teachers who participated in the training at the Center for in-service teacher education in the School of Agriculture and Life Sciences, Seoul National University and at the Center for in-service teacher education of Chungnam National University. After screening, 685 responses were used in the analysis. As a result, it turned out that only 112 vocational teachers(16.5%) participated in the field practice for more than 4 weeks when they were in pre-service education. However, vocational teachers seemed to perceive that experience of field practice was generally required in pre-service education(average 4.07). In-depth questionnaire was conducted on 143 respondents who replied that they participated in field practice program for more than 4 weeks and those who participated in the program for less than 4 weeks but completed the paperwork. Most of vocational teachers who participated in field practice were placed in small and medium sized enterprises, stayed at home or relatives' home and commuted by the bus or subway. In this research, 34.8% of the vocational teachers who participated in field practice received financial compensation and 80.3% of the teachers got credit recognition. The perception of satisfaction on field practice program was found to be moderate(average 3.51).

  • This study was conducted to investigate the variables affecting the quality of life according to the degree of obesity of male and female college students. The research data used the data of the 8th year (2019) of the National Health and Nutrition Survey. Among the survey data, 287 students enrolled in college were enrolled. As a result of the study, the body mass index according to sex was 23.71kg/m2 for male students, 21.31kg/m2 for female students, and male students were overweight, and female students showed normal weight. The quality of life score according to gender was 0.97 points for male students and 0.98 points for female students, indicating a high quality of life score for female students. In the results of a regression analysis conducted to investigate the effect of obesity on the quality of life of college students, boys had normal weight (β=0.053, p=0.003), overweight (β=0.041, p=0.030) and obese weight compared to underweight. The quality of life was significantly higher in (β=0.046, p=0.012). However, there was no significant relevance in female students. In the future, it is considered that the education program for obese body type and the education program for underweight should be combined with the university's health-related education program.

  • Calcium-dependent protein kinases (CDPKs) are known to be involved in regulating plant responses to abiotic stresses such as salinity, cold temperature and dehydration,. Although CDPKs constitute a large multigene family consisting of 31 genes in rice, only a few rice CDPKs' functions have been identified. Therefore, in order to elucidate the functions of OsCPK11 in rice, this study was intended to focus on the expression pattern analysis of OsCPK11 in wild type and ND0001 oscpk11 mutant plants under these abiotic stresses. For the salt, cold and drought stress treatment, seedlings were exposed to 200 mM NaCl, 4℃ and 20% PEG 6,000, respectively. RT-PCR and quantitative real-time PCR were performed to determine the expression patterns of OsCPK11 in wild type and ND0001 mutant plants. RT-PCR results showed that OsCPK11 transcripts in the wild type and heterozygous mutant were detected, but not in the homozygous mutant. Real-time PCR results showed that relative expression of OsCPK11 of wild type plants was increased and reached to the highest level at 24 hr, at 6 hr and at 24 hr under salt, cold and drought stress conditions, respectively. Relative expression of OsCPK11 of ND0001 homozygous plant was significantly reduced compared to that of wild type. These results suggested that oscpk11 homozygous mutant knocks out OsCPK11 and OsCPK11 might be involved in salt, cold and drought stress signaling by regulating its gene expression.
