Surveying perception of majors to students of Department of dental technology 433(48.3%) and Department of dental hygiene 463(51.7%), and their sex rates 272 (30.4%) for males and 624 (69.6%) for females, 896 examines in total, have let us to know the level of student's perception of their majors and now able to adjust the level of major's lectures and maximize the ability to study has brought these conclusions. 1. Although the hometowns of students had similar rates between large and small cities disregarding their departments, the type of highschool had differences for the academic highschool graduators were the most. Also, CSAT was the highest than other specialized types when entering. 2. Self selection considering employment percentage was the highest for the student's choice of selecting department of dental hygiene and dental technology. 3. For the satisfaction of school and education systems, "satisfied" and "normal" were as high as 74% in both department of dental hygiene and dental technology for school satisfaction, and 75%, 74% for satisfaction of environment from the two departments. 4. As for the satisfaction of department and environment, department of dental hygiene and dental technology both answered "satisfied" and "normal" the most, but in satisfaction of companions, they have shown relatively high satisfaction by answering "very satisfied" and "satisfied". 5. Difficulties of majors relating to the perception of learning, department of dental technology and dental hygiene both answered too much to memorize and hard to understand. 6. Department of dental technology's try for majors relating to the level of perception of learning have shown that they have high understandings in proportion to how much they try but for department of dental hygiene has shown not much differences. 7. Department of dental hygiene had higher stress than department of dental technology in studying majors and there were both some differences statistically.

This study analyses customer data from a US online lending platform to empirically document the discriminatory treatment that low- and middle-income borrowers face in financial markets. Researchers are using financial data from nearly 2.93 million loans between 2007~2020 of the Lending Club on the open-source Kaggle platform. We find that thin-filers borrowers, especially those with lower credit scores, receive loans at higher interest rates. This discriminatory treatment undermines financial inclusion and has the potential to increase social inequality. The significance of this research is that it sheds substantial light on the problem of inequality in financial markets and, based on the findings, suggests concrete measures to ensure equitable access to finance for all customers and enhance sustainable financial inclusion. In doing so, we propose a shift towards enhancing the social responsibility of institutions.

Objectives: Blood mercury levels among adults living in certain areas of the Gyeongsang Provinces have been shown to be very high (Kunwee County $29.6{\mu}g/L$, Yeongcheon-city $26.7{\mu}g/L$). The purpose of this project was to determine mercury exposure levels in schoolchildren and factors related with their mercury levels in high mercury exposure areas identifyed by the 2007 Korea National Environmental Health Survey. Methods: From June to September 2010, 1,097 students from grades 3 to 6 at 19 elementary schools participated in this study, including 294 students from 10 elementary schools in Kunwee County, 529 students from Yeongcheon City, 122 students from two elementary schools in Pohang City, North Gyeongsang Province, and 152 students from two elementary schools in Ulsan Metropolitan City. Biological samples from schoolchildren, including whole blood, urine and hair, were collected to measure total mercury at the time of a health check up. Information about children was collected by questionnaire. Total mercury concentrations in blood were measured using the Direct Mercury Analyzer 80 with the gold-amalgam collection method. Results: The mean mercury levels were $2.70{\mu}g/L$ in 1,091 blood samples, $2.25{\mu}g/g-creat.$ in 820 urine samples and $1.03{\mu}g/g$ in 1,064 hair samples. Blood mercury levels in the schoolchildren was slightly higher than the result of $2.4{\mu}g/L$ from a 2006 survey of elementary school children on exposure and health effects of mercury by the National Institute of Environmental Research. However, 0.3% and 4.5% of participants exceeded the reference level of blood mercury by CHBMII ($15{\mu}g/L$) and the US EPA ($5.8{\mu}g/L$), respectively. The reference level of urine by CHBMII ($20{\mu}g/L$) was exceeded by 0.4% of participants. As factors, residence period in the study areas, residence type, father's education level and income all showed significant associations with mercury level in the biological samples. The number of dental amalgam sides showed an association with urine mercury. Fish intake preference and fish intake frequency were important factors in mercury levels. In particular, intake of shark meat and recent intake of shark meat were associated with higher mercury levels. In this regard, participation in the performance of an ancestral rite showed a relation with higher mercury levels. Conclusion: The intake of shark meat was very important factor to high mercury exposure level. It is recommended to monitor and manage students with high mercury exposures who exceeded CHBM II and EPA guidelines, and include blood mercury testing in the Children's Health check up for this province.

The purposes of this study were to explore food-related lifestyle segments for commercialization of ready-to-eat Korean foods, to identify their demographic characteristics, and to evaluate perceptions and preferences related to Korean foods. The subjects consisted of 266 Koreans and 212 non-Koreans in Seoul, Gyeonggi, and Daejeon, Korea including in Grapevine of the US. Koreans' scores for food-related lifestyle of taste seeking and convenience seeking were significantly higher than those of non-Koreans. Through cluster analysis, four segments for Koreans were identified: health-oriented group, diet-oriented group, rationality-oriented group, and price-sensitive group. The clusters for non-Koreans were classified into four segments: taste-oriented group, rationality-oriented group, diet-oriented group, and convenience-oriented group. Significant differences were detected among the four segments in terms of demographic characteristics. There were significant differences in perceptions and preferences related to Korean foods by food-related lifestyle segments of non-Koreans. Japchae, Bibimbap, and Naengmyeon were selected as the most likely to purchase ready-to-eat food items for Korean clusters, whereas Bulgoggi and Bibimbap were selected for non-Korean clusters. This study shows that food companies wanting to promote commercialization of Korean foods should consider characteristics of each segment of food-related lifestyle.

The Purposes of this study were to understand the types of appellations used by nurses and doctors for patients in a hospital and to analyze satisfaction and reason about appellation for patient. This would enable us to provide basic data on culturally suitable appellations for admitted patients. 454 patients at K University hospital in Seoul were subjects for this study. Subjects were interviewed individually using a questionnair and frequency $X^2-test$. Results are as follows. 1. The most frequently used type of appellations in hospitals was '-ssi ; -sir' used by 88.1% of the nurses and 83.9% of the doctors. About 3 quaters of the medical staff used '-ssi' while none used job position. 2. 93.2% of the patients were satisfied with the appellations used by nurses and 93.0% of the patients were satisfied with the appellations used by the doctors 43.7% didn't think appellations were important and 44.3% thought it natural to use the appellation. The most satisfactory form of appellation used by nurses was '-ssi' to 93.3% of patients. All were satisfied with '-nim ; -sir', '-teacher' and there was no statistically significance. On the other hand, the level of satisfaction and the appellation used by doctors showed a relationship($X^2=19.72$, p=.000). Every patient was satisfied with '-nim' and '-teacher' but 19.9% were dissatisfied with the others of appellations. 3. Most patients preferred to be called '-ssi' by nurses(77.3%) and doctors(78.7%) respectively. The dominant reason being accuracy(45.8%), naturalness(33.9%) for nurses and 43.8% and 45.4% respectively for doctors. 4. The relationship between the type of appellations requested of nurses and general characteristics showed that age($X^2=83.91%$ p=.000), level of education($X^2=33.35$ p=.000), and occupation($X^2=38.22$ p=.033) were related to the type of appellation. The type of appellation requested of doctors was related to the age($X^2=72.56$ p=.000), level of education($X^2=30.01$ p=.000), and occupation($X^2$=42.90 p=.010). Generally, '-ssi' was requested of doctors and nurses, but lower age group or higher age group(over 61), those in elementary schools or elementary school graduates snd students preferred being called by their first names or grandfather, grandmother. From the results above, we can see that the most general type of appellation used for patients by the medical staff is '-ssi' and most patients were satisfied with the appellation but, the reason being that such appellations were accepted without concern. This shows that most are not adequately satisfied with the appellation. Only a small number of people use '-nim' and '-teacher' but is the preferred and frequently used types of appellation. Therfore, a continuous research of appellations used for patients with patients using '-nim' and an investigation with nurses' opinions of appellations for patients as the subject are required.

Trigonometry allows us to recognize the usefulness of mathematics through connection with real life and other disciplines, and lays the foundation for the concept of higher mathematics through connection with trigonometric functions. Since international comparisons on the trigonometry area of textbooks can give implications to trigonometry teaching and learning in Korea, this study attempted to compare trigonometry in textbooks in Korea, Australia and Finland. In this study, through the horizontal and vertical analysis presented by Charalambous et al.(2010), the objectives of the curriculum, content system, achievement standards, learning timing of trigonometry content, learning paths, and context of problems were analyzed. The order of learning in which the three countries expanded size of angle was similar, and there was a difference in the introduction of trigonometric functions and the continuity of grades dealing with trigonometry. In the learning path of textbooks on the definition method of trigonometric ratios, the unit circle method was developed from the triangle method to the trigonometric function. However, in Korea, after the explanation using the quadrant in middle school, the general angle and trigonometric functions were studied without expanding the angle. As a result of analyzing the context of the problem, the proportion of problems without context was the highest in all three countries, and the rate of camouflage context problem was twice as high in Korea as in Australia or Finland. Through this, the author suggest to include the unit circle method in the learning path in Korea, to present a problem that can emphasize the real-life context, to utilize technological tools, and to reconsider the ways and areas of the curriculum that deal with trigonometry.

Objectives : This study was conducted to examine the relationships of the several socioeconomic position indicators with the mortality risk in a representative longitudinal study of South Korea. Methods : The 1998 National Health and Nutrition Examination Survey was conducted on a cross-sectional probability sample of South Korean households, and it contained unique 13-digit personal identification numbers that were linked to the data on mortality from the National Statistical Office of Korea. Of 5,607 males and females, 264 died between 1999 and 2003. Cox's regression was used to estimate the relative risks (RR) and their 95% confidence intervals (CI) of mortality. Results: Socioeconomic differences in mortality were observed after adjustments were made for gender and age. Compared with those people having college or higher education, those people without any formal education had a greater mortality risk (RR=2.21, 95% CI=1.12-4.40). The mortality risk among manual workers was significantly greater than that for the non-manual workers (RR=2.73, 95% CI=1.47-5.06). A non-standard employment status was also associated with an increase in mortality: temporary or daily workers had a greater mortality risk than did the full-time workers (RR=3.01, 95% CI=1.50-6.03). The mortality risk for the low occupational class was 3.06 times greater than that of the high and middle occupational classes (95% CI=1.75-5.36). In addition, graded mortality differences according to equivalized monthly household income were found. A reduction of monthly household income by 500 thousand Korean Won (about 400 US dollars) was related with a 20% excess risk of mortality. Self-reported poor living standards were also associated with an increased risk of mortality. Those without health insurance had a 3.63 times greater risk of mortality than the insured (95% CI=1.61-8.19). Conclusions: This study showed the socioeconomic differentials in mortality in a national longitudinal study of South Korea. The existence of socioeconomic mortality inequalities requires increased social discussion on social policies in Korean society. Furthermore, the mechanisms for the socioeconomic inequalities of mortality need to be explored in future studies.

This study examines garden activity and garden plant preferences for development of the garden activity program using community garden aimed for communication and integration for multicultural age. As a result, for members of multicultural society had high portion of floral arrangement and crafts, growing plants in both indoors and outdoors garden for their garden activities, and using plants for cooking, growing plants in both indoors and outdoors garden was of higher portion for native korean. In the garden plant preferences, members of multicultural society liked ornamental plants the best, due to the environmental correspondence between the plant's place of origin and their home country, while native koreans tend to prefer vegetables, reflecting the recent interest in pro-environment crops and rise in demand of urban farming, veranda gardening and weekend farming. In this study, the garden activity program for communication and integration categorized the value of garden activity into three categories; the value of respect for life, the value of consideration through caring, the value of plant ethics, based on the above preference results. The value of respect for life can be achieved by understanding the meaning of life, experiencing the will to live, and understanding the characteristics of plants and me. The value of consideration of caring comes from waiting and nurturing for living things that are different from me and adapting to the environment as a living The value of plant ethics can give us the insights for human relationships, by understanding and experiencing the natural ecosystem and plant co-existing in it. The eight-session garden activity program also went through validity verification process by experts on gardening and multiculture, and the effectiveness of the program was proved.
