This study estimates the total health expenditure of ambulatory dental care and explores the factors related to disbursements. The study used two waves of a 2008 Korea Health Panel (KHP) survey, of which each wave is composed of 7866 households and 24,659 persons. The KHP includes missing expanses of reimbursement data of the National Health Insurance (NHI), such as out-of-pocket, drugs, and private health insurance. The study estimates total monthly ambulatory dental expenditure and the sub-special categories of dental care. For influential factors analyses, the study exploits log-linear model with age, gender, education, job, equivalence income, the status of chronic diseases, means-tested benefit recipients, private insurance, and the composite deprivation index as independent variables. The total monthly outpatient health spending is estimated to be 102,468 won per household, and for dental, each household spends 31,115 won per month. Older age, means-test recipients, non-regular workers are more likely to spend less money on dental care, whereas private insurers, high income, and those who live in less deprived areas are more likely to spend more money for dental services. From the study we found that the KHP data are more suitable to estimate the total amount of health care markets, especially when the NHI coverage is low, such as for dental care in Korea.

This study conducts a survey based on 425 Chinese females in their twenties to thirties in order to examine the relevance between the cognitions of appearance effectiveness, ideal appearance seeking behavior and clothing image preference which have effects on their self-identity and interpersonal relations. The results of this study are as follows ; First, from the factor analysis for cognition of appearance effectiveness, and ideal appearance seeking behavior, a total of 4 factors such as psychological benefits, social benefits factors, pursuit of plastic surgery and pursuit of beauty treatment are being were drawn. As a result, there are significant correlations between heights of demographic variables and the cognition of appearance effectiveness, together with the ideal appearance seeking behavior. Respondents with higher heights represent the higher cognitions of appearance effectiveness, while the respondents with lower heights show more pursuits of beauty treatment behavior to reach the ideal image. Second, factor analysis of the clothing images are 4 factors such as classic-trendy, natural-dynamic, casual-formal, and masculine-feminine images. There are significant correlations between the four factors from clothing preference images and four factors from the cognition of appearance effectiveness, and ideal appearance seeking behavior. This suggests that higher social status such as job, income, residential district, and age among the demographic factors has greater effects on the clothing image preference.

As competition has deepened between business institutions, it has been difficult to predict and respond quickly to business environment. Most business firms have started to introduce Enterprise Resource Planning (ERP) in order to improve their business environment. However, it increases the probability of failure to implement the systems without considering the structural characterisitcs of the organizations. The paper studies what influence the characteristic variables of organizational structure and management system have on the performance of the ERP systems of small and medium-sized enterprises. Also, since it is important to compare the level of information system of Korea and China in the midst of the rapid growth of Chinese economy, the paper&nbs p;compares the ERP performance of Chinese and Korean small and medium sized enterprises that implemented ERP system.

Background: Occupational accidents are unplanned events that cause damage. The socio-economic impacts and human costs of accidents are tremendous around the world. Many fatalities happen every year in workplaces such as electricity distribution companies. Some electrical injuries are electrocution, electric shock, and burns. This study was conducted in an electricity distribution company (with rotational 12-hour shift work) in Iran during an 8-year period to survey descriptive factors of injuries. Methods: Variables collected included accident time, age of injured worker, employment type, work experience, injury cause, educational background, and other information about accidents. Results: Results indicated that most of the accidents occurred in summer, and 51.3% were during shift work. Worker negligence (malpractice) was the cause of 75% of deaths. Type of employment had a significant relationship with type of injuries (p < 0.05). Most injuries were electrical burns. Conclusion: High rate of accidents in summer may be due to the warm weather or insufficient professional skills in seasonal workers. Shift workers are at risk of sleep complaints leading to a high rate of work injuries. Acquiring knowledge about safety was related to job experiences. Temporary workers have no chance to work all year like permanent workers, therefore impressive experiences may be less in them. Because the lack of protective equipment and negligence are main causes of accidents, periodical inspections in workshops are necessary.

The purpose of this study is to verify the mediating effect of pay satisfaction on the relation between procedural justice and organizational commitment. A survey was conducted to examine the mediating effect of pay satisfaction on the responses of 529 employees. The study chose sex, age, education, position, job type and career as control variable, and the regression model which treated procedural justice as independent variable and organizational commitment as criterion variables were set. A pay satisfaction was supposed as mediating variable of these relationships. The data analysis was conducted by SAS 9.4ver and LISREL 8.80. The results of this study confirm underneath the followings. First, the relation of procedural justice and organizational commitment are significantly unique. Second, procedural justice are positively related to pay satisfaction. Third, pay satisfaction is significantly positively related to organizational commitment. Fourth, the pay satisfaction is partially mediated on the relationship between procedural justice and organizational commitment. This means that the pay satisfaction mediates the relation of procedural justice and organizational commitment. These results are different from the prior researches which had treated pay satisfaction as mediating variable of procedural justice and organizational commitment. Based on the findings of the study, this study presented managerial implications and suggestions for future studies.

A study was performed to develop as a screening tool the Simple Evaluation Questionnaire for Screening the Over-weight-type Dietary Pattern in 30 to 49 Year Old Adults. We used the data from the 30 to 49 year old subjects who participated in the three surveys - the health behavior survey, the dietary habit survey and the food intake survey - as the National Health and Nutrition Survey 1998. The 3,598 adults were classified into to two body fatness groups of normal (including underweight) and overweight (including obese) on the basis of their relative body weight (RBW) When comparing variables between the two groups, significant differences were found in gender, education, job, employment status, perceived health status, sadness / depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, drinking pattern (yes/no) , amount of alcoholic drinks, frequency of intoxication or drunkeness, amount of alcoholic drinks when drunk, intensity of exercise, frequency of exercise, exercise duration, skipped meals, small meals and drug supplements. In terms of food intake, there were significant differences in the daily food intake in terms of breakfast, dinner, daily kimchi and dairy products. In terms of mealtimes, we found differences in the amount of cooked rice at breakfast, kimchi at lunch, soup / kuk at dinner, fresh vegetables for snacks, fried foods for snacks between breakfast and lunch, and fruits /juices for snacks between lunch and dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis three times, we chose 10 questions for a simple evaluation of dietary patterns for the overweight-type category in order to give one point each. Among them we selected two questions to add one additional point and one question to add two additional points. The average scores of the overweight and normal groups, as shown by the developed questionnaire, were $5.97 \pm 2.36 \pm 7.36 \pm 2.21$, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 67%, 59% and 62%, respectively.

The purpose of this research was to develop a rapid setting cement latex modified concrete (RSLMC) for bridge deck repairing and overlaying. The main experimental variables were latex contents, antifoamer contents and water-cement ratioes. The workability, strength development and permeability were measured as responses. The results showed that latex content increased the slump and reduced the unit water required for same workability. The air contents were measured as 8.0∼9.0％ and 2.0∼3.0％ without antifoamer and with 1.6∼3.2％ of antifoamer, respectively. This resulted in the increment of compressive strength development by 10∼20 ％. The flexural strength of RSLMC increased greatly as the latex content increased, but not in compressive strength. The compressive strength and flexural strength developed enough for opening the overlayed RSLMC to the traffic after 3 hours of RSLMC placement. The permeability of RSLMC was evaluated as negligible due to its very low charge passed. Thus, RSLMC could be used at repairing or overlaying the concrete bridge deck at fast-track job sites.

This study was undertaken to investigate the influence of teamwork skill and decision making competency on nursing work performance. A total of 170 nurses more than one years working experience were recruited from two university hospitals. Data were collected during March, 16 to 25, 2016 using a structured self-report questionnaires. Data were analyzed using the IBM SPSS/WIN 21.0 program. Teamwork skill and decision making competency for nursing work performance showed significant positive correlation. The significant predictors of nursing work performance among nurses were total clinical experience (${\beta}=.23$, p<.001), teamwork skill (${\beta}=.61$, p<.001) and decision making competency (${\beta}=.13$, p=.015). These variables explained 66% of the variance in nursing work performance among nurses. The results indicate that nurses' teamwork skill and decision making competency are factors positively influencing on nursing work performance.
