  • Background: The determination of the amount of radionuclides and internal dose for the worker who may have intake of radionuclides results in a variation due to uncertainty of measurement data and ingestion information. As a result of this, it is possible that for the same internal exposure scenario assessors could make considerably different estimation of internal dose. In order to reduce this difference, internal exposure scenarios for nuclear facilities were developed, and intercomparison were made to determine the harmonization of dose assessment results among the assessors. Materials and Methods: Seven cases on internal exposures incidents that have occurred or may occur were prepared by referring to the intercomparison excercise scenario that NRC and IAEA have carried out. Based on this, 16 nuclear facilities concerned with internal exposure in Korea were asked to evaluate the scenarios. Each result was statistically determined according to the harmonization discrimination criteria developed by IDEAS/IAEA. Results and Discussion: The results were evaluated as having no outliers in all 7 cases. However, the distribution of the results was spread by various causes. They can be divided into two wide categories. The first one is the distribution of the results according to the assumption of the intake factors and the evaluation factors. The second one is distribution due to misapplication of calculation method and factors related to internal exposure. Conclusion: In order to satisfy the harmonization criteria and accuracy of the internal exposure dose evaluation, it is necessary that exact guidelines should be set on low dose, and various intercomparison cases also be needed including high dose exposure as well as the specialized education. The aim of the blind test is to make harmonization evaluation, but it will also contribute to securing the expertise and high quality of dose evaluation data through the discussion among the participants.

  • Objectives : There are lots of reports that cardiovascular disease, including hypertension, cerebro-vascular accident, and coronary heart disease, is related to atherosclerotic changes. Increased serum levels of lipids could play a role in these changes. This study aimed to investigate the relationship between PWV and risk factors of cardiovascular disease, including serum lipid values. Methods : This study included 261 subjects ($49.32{\pm}11.79$ years, 112 male) who underwent PWV and serum lipid evaluation. We investigated the correlation between serum lipid values, blood pressure, body mass index (EMI) and PWV. Pearson's correlation and partial correlation analysis were applied to examine the relationship between PWV and risk factors of cardiovascular disease. Results : Serum triglyceride, total cholesterol, systolic blood pressure, and diastolic blood pressure were significantly correlated with PWV. Partial correlation coefficient adjusted by age yielded significant correlation between serum triglyceride, systolic blood pressure, diastolic blood pressure and PWV. Conclusion : In this study, it seems that there are significant relationships between PWV, triglyceride and blood pressure. We could suggest that PWV might have some relationships with Dam-eum and blood stasis in oriental theory.

  • The effects of environmental factors on adolescent’s socialization were examined according to the gender. Data were drawn from 1,412 adolescents. A hypothesized model was tested for male and female students separately by the links among housing, family conflicts, parent-adolescent relationship, family stress, peer relations, mass media, school atmosphere, consumption, consumer socialization, and adolescent’s socialization. There was no difference between male and female students in the predictability of the effects of environmental factors on internal and external socialization. For male students, the internal socialization was directly related to mass media, consumer socialization, peer relations, family stress, mother-adolescent relations, and school atmosphere. The external socialization was directly related to mass media, school atmosphere, consumer socialization, father-adolescent relations, housing, and mother-adolescent relations. For female students, the internal socialization was directly related to mass media, peer relations, father-adolescent relations, and consumer socialization. The external socialization was directly related to mass media, followed by consumer socialization, mother-adolescent relations, school atmosphere, housing, and peer relations. The findings are consistent with a growing body of literature showing that the environmental factors are related to male & female adolescent’s socialization.

  • Background: Measurement of peak expiratory flow rate (PEFR) in a follow-up examination for a chronic airway disease is useful because it has the advantages of being a simple measurement and can be repeated during examination. The aim of this study was to examine the annual decrease of PEFR in asthma and chronic obstructive pulmonary disease (COPD) patients and to confirm the factors which influence this decrease. Methods: From May, 2003 to September, 2010, the annual decrease of PEFR was obtained from asthma and COPD patients attending an outpatient pulmonary clinic. PEFR was measured using a Mini-Wright peak flow meter (Clement Clarke International Ltd. UK), and we conducted an analysis of factors that influence the change of PEFR and its average values. Results: The results showed an annual decrease of $1.70{\pm}12.86$ L/min the asthmatic patients and an annual decrease of $10.3{\pm}7.32$ L/min in the COPD patients. Age and $FEV_1$ were the predictive factors influencing change in asthma, and $FEV_1$ and smoking were the predictive factors influencing change in COPD. Conclusion: We confirmed the annual decreasing PEFR in patients with chronic airway disease and identified factors that work in conjunction with $FEV_1$ to influence the change.

  • The purpose of this study was to investigate how internal marketing affects self-efficacy and hospital image in university hospital nurses. In addition, it was to identify which factors of internal marketing is the most important factor perceived by the nurses. The sample consisted of 228 nurses working in one university hospital located in Changwon city of Gyeongnam province. The measurements included internal communication (5 items), empowerment (5 items), reward (3 items), education and training (5 items), working environment (3 items), leadership (5 items), self-efficacy (5 items), and hospital image (8 items) based on a review of related previous studies. Survey data were analyzed employing SPSS version 20.0 and AMOS version 20.0. The nurses rated internal communication (0.887) of the internal marketing sub-factors the most important, while they evaluated working environment (0.802) the lowest. The internal marketing perceived by nurses has a positive effect on self-efficacy (0.476) and hospital image (0.674). Nurses' self-efficacy also had a positive effect on hospital image (0.226). The findings reveal that the managers should build a positive climate of internal marketing activities in order to enhance nurses' self-efficacy and hospital image.

  • In recent years, the domestic construction business is continuously stagnated caused by housing depression, global financial crisis etc. To overcome these difficulties, the construction companies should reinforce the internal marketing like the service business. However, it is not easy to conduct active internal marketing reinforcement since the companies do not directly receive customers under special situation like construction. Therefore, it is necessary to resolve the urgent issue by selecting order of priority among internal marketing factors. To address this issue, the objective of this study is to analyze the internal marking factors by using Analytic Hierarchy Process. As a result, the first and second factor represents the internal communication and working condition and environment respectively. The findings of this study will contribute to apply the internal marketing into construction industry.

  • This study utilized longitudinal data from the 2013 year (Secondary Middle School) to 2017 year (Secondary High School) of the Seoul Education Termination Study. Using the latent growth model and the piecewise growth model, we investigated the changes in mathematics academic achievement, internal factors(self-concept, self-control, self-assessment of life satisfaction), and external factors(school climate, guardians) as students' grades increased, and examined whether internal factors and external factors influence the changes in mathematics academic achievement. We examined whether internal and external factors influence the change in academic achievement. As a result of analysis, it was found that mathematics academic achievement remained unchanged from the first grade of middle school to the second grade of middle school, and steadily increased from the second grade of middle school to the first grade of high school, and then decreased slightly in the second grade of high school. The internal and external factors had little change. It has been found that self-concept, self-control as internal factors, and school climate as external factors influence changes in mathematics academic achievement.
