Background: In situ gamma spectrometry has been used to measure environmental radiation, assumptions are usually made about the depth distribution of the radionuclides of interest in the soil. The main limitation of in situ gamma spectrometry lies in determining the depth distribution of radionuclides. The objective of this study is to develop a method for subsurface characterization by in situ measurement. Materials and Methods: The peak to valley method based on the ratio of counting rate between the photoelectric peak and Compton region was applied to identify the depth distribution. The peak to valley method could be applied to establish the relation between the spectrally derived coefficients (Q) with relaxation mass per unit area (${\beta}$) for various depth distribution in soil. The in situ measurement results were verified by MCNP simulation and calculated correlation equation. In order to compare the depth distributions and contamination levels in decommissioning KRR site, in situ measurement and sampling results were compared. Results and Discussion: The in situ measurement results and MCNP simulation results show a good correlation for laboratory measurement. The simulation relationship between Q and source burial for the source layers have exponential relationship for a variety depth distributions. We applied the peak to valley method to contaminated decommissioning KRR site to determine a depth distribution and initial activity without sampling. The observed results has a good correlation, relative error between in situ measurement with sampling result is around 7% for depth distribution and 4% for initial activity. Conclusion: In this study, the vertical activity distribution and initial activity of $^{137}Cs$ could be identifying directly through in situ measurement. Therefore, the peak to valley method demonstrated good potential for assessment of the residual radioactivity for site remediation in decommissioning and contaminated site.

The purpose of this study was to investigate the relationship between oral health behaviors and periodontal diseases in adult obese people. Using the original data of the second phase of the 6th National Health and Nutrition Survey, the final 4381 adults were extracted. We analyzed frequency and technical statistics and chi - square test and multiple logistic regression analysis using SPSS statistical program to confirm the association between body mass index, number of brushing, drinking, smoking and oral health status and behavior. As a result, the prevalence of periodontal disease decreased as the number of toothbrushing increased, and the prevalence of periodontal disease increased as the body mass index increased. Through this study, obesity, a global health issue, should be more concerned with oral care and develop oral health management programs.

This study aimed to identify the relationship between depression of the elderly and low back pain. Data were obtained from cross-sectional surveys conducted as a part of the Community Health Survey 2008. The final analysis included data from 3,647 of the 3,649 elderly participants (aged over 65 years), as 2 responses were excluded since they were inaccurate. Data were analyzed with SPSS for Windows (ver. 19.0), using a Rao-Scott ${\chi}^2$-test and Logistic regression by applying a proper weighting. The significance threshold was set as p<0.05. Factors related to the depression of the elderly were low back pain, subjective health status, average sleep duration. Further, depression score was 1.38 times higher in elderly adults with low back pain than elderly adults without low back pain. In order to decrease depression of the elderly with low back pain the development of a program to decrease activities of daily living discomfort and management of low back pain will need to be determined. It is considered necessary to conduct further study to follow through the analysis of the various variables by applying them to the elderly with low back pain and depression.

Objectives: Food allergy appears to be increasing in prevalence and can potentially result in significant damaging impact on children's mental and physical health. This study investigated how dietitians/nutrition teachers in Incheon, where a fatal fool allergy incidence occurred, manage food allergy issues in school lunch systems. Methods: A survey with a pre-tested questionnaire was conducted with 358 dietitians/nutrition teachers in Incheon area. The final analytical sample included questionnaire data from 208 study participants (58.1%). Statistical analyses used SPSS ver 19.0. Results: A total of 99.5% respondents reported having received food allergy education. The respondents showed a correction rate of the food allergy test slightly higher than 70%, where nutrition teachers and respondents working in elementary schools had correction rates higher than dietitians and those working in middle schools (p<0.05). All respondents reported regular monitoring to identify students with food allergy and making notification of allergy-prone foods on menu in their school. More nutrition teachers provided "elimination meals" (57.6%) or "replacement meals" (37.0%) than dietitians (43.1%, 19.8%, respectively) (p<0.05). Elimination and replacement meals were provided more in elementary schools than in middle schools (p<0.05). Although counseling students with food allergy on nutrition was done by 64.9% of respondents, the areas of counseling were limited to basics of food allergy and how to use the notification system on menu. To prepare for handling food allergy events effectively, networks with regional clinics or hospitals (34.1%), hotline with parents (87.4%), and keeping an Epi-Pen ready (46.7% elementary school) were established. Only 34.1% of respondents knew how to use Epi-Pens. Conclusions: Dietitians and nutrition teachers in Incheon widely adapted food allergy management methods. It appears that education/training on food allergy for dietitians/nutrition teachers can move on from teaching basics of food allergy to providing applicable food allergy management methods at school system.

Objectives : The purpose of this study was to determine the impact of the sociodemographic and health characteristics on the out-of-pocket health spending of the individuals aged 20 and older in Korea. Methods : We used the data from the 2001 National Public Health and Nutrition Survey. The final sample size was 26,154 persons. Multiple linear regression models were used according to the age groups, that is, one model was used for those people under the age of sixty-five and the other was used for those people aged sixty-five and older. In these analyses, the expenditures were transformed to a logarithmic scale to reduce the skewness of the results. Results : Out-of-pocket health expenditures for those people under the age of 65 averaged 14,800 won per month, whereas expenditures for those people aged 65 and older averaged 27,200 won per month. In the regression analysis, the insurance type, resident area, self-reported health status, acute or chronic condition and bed-disability days were the statistically significant determinants for both age groups. Gender and age were statistically significant determinants only for the non-elderly. Conclusions : The findings from this study show that the mean out-of-pocket health expenditures varied according to the age groups and also several diverse characteristics. Thus, policymakers should consider the out-of-pocket health expenditure differential between the elderly and non-elderly persons. Improvement of the insurance coverage for the economically vulnerable subgroups that were identified in this study should be carefully considered. In addition, it is necessary to assess the impact of out-of-pocket spending on the peoples' health care utilization.

The purpose of this study was to obtain data to improve customer orientation by managing emotional labor in foodservice employees. This study investigated the correlation between emotional labor (surface acting, deep acting), job burnout (emotional exhaustion, cynicism), and job engagement (vigor, dedication, absorption) in high school foodservice employees, and how they affect customer orientation. Our survey was administered to 330 school foodservice employees in the Busan area from June 2 to June 27, 2015. A total of 321 questionnaires were used for final analysis. The mean values for deep acting (p<0.01), cynicism (p<0.01), and dedication (p<0.05) significantly according to the position of the emproyees. The mean customer orientation significantly according to employment status (p<0.01) and meal service time (p<0.01). There was positive correlation (p<0.01) between surface acting, and emotional exhaustion cynicism, but negative correlation (p<0.01) between surface acting and vigor, dedication, absorption, and customer orientation. Deep acting had negative correlation (p<0.01) with emotional exhaustion and cynicism, positive correlation (p<0.05) with vigor, dedication, absorption, and customer orientation. Surface acting had negative influences on emotional exhaustion and cynicism, cynicism had negative influences on vigor, dedication, absorption, and customer orientation. Deep acting had positive influences on absorption and customer orientation, absorption had positive influences on customer orientation. Thus, nutrition teacher(dietitian) should educate foodservice employees the positive effects of deep acting to change their surface acting to deep acting, while actively managing internal customers.

Objectives : The purpose of this study was to examine the awareness-perception factors and oral health promotion behavior of dental hygiene and nonhealth-related students in an effort to find out factors affecting their oral health promotion behavior. Methods : The subjects in this study were students in the three-year-course dental hygiene and students in the two-year-course nonhealth-related department in G college located in the city of Gwangju. After a survey was conducted, the collected data were analyzed and compared. Results : 1. The dental hygiene students were statistically significantly ahead of the nonhealth-related students in perceived oral health knowledge(p<0.001), awareness of the importance of oral health(p<0.001), perceived oral health status(p<0.001) and oral health interest(p<0.001). 2. Concerning the characteristics of oral health promotion behavior, the dental hygiene students were statistically significantly better at toothbrushing(p<0.001) and the use of dental floss(p<0.001) than the nonhealth-related students. 3. Regarding factors affecting oral health promotion behavior, oral health knowledge and oral health interest were identified as the factors that impacted on oral health promotion behavior. Out of the two, oral health interest exercised a greater influence on that. Conclusions : It seems that oral health education could motivate students to be concerned about their oral health, to acquire knowledge on that and eventually to change their oral health behavior and attitude. As for college students, oral health education provides a final chance for them to check their oral health knowledge, attitude and oral health promotion behavior before they start to work as full-fledged adults, and institutional measures should be taken to offer more intensive official oral health education.
