The aims of this study are to investigate the differences of the preschoolers' executive function and verbal ability according to their age, and to identify whether the preschoolers' executive function is related to their verbal ability. The participants in this study are 151 children, ages 3-and 5-years old from five child-care centers located in a middle-income region of Seoul. Statistical methods used for the data analysis are the frequencies, means, standard deviations, an independent t-test, and Pearson correlation. The major findings are as follows. First, an age difference is found for children's executive function. The 5-year-olds are more likely to succeed on tasks of executive function than the 3-year-olds. Also, age difference is found for children's verbal ability. The 5-year-olds perform better on tests of verbal ability than the 3-year-olds. Last, the 3-year-olds' and 5-year-olds' executive function is related to their verbal ability. Inhibition and cognitive flexibility are significantly correlated with verbal ability. These results suggest that preschoolers' executive function and verbal ability develop during preschool age. These results also suggest that preschoolers' executive function is related to their verbal ability.

The influences of depression and health anxieth on the elderly's drug use and nutritional status were evaluated by interviews with questionaire from August to October in 1996. One hundred and thirty-one male and 231 female elderly in Chung-buk area were the sample for this study. Men's depression score was 22.3 and 25.2 for women, respectively out of 27. Women showed a significantly higher score for depression and health anxiety than men. Gender, age, marital status, number of family, education, income, medical insurance, and mobility and region significantly affected the health anxiety score. The higher depression score the elderly had, the more frequently they took drugs. Conversely. the higher depression score the elderly had, the less frequently they took nutritional supplements. For women, the higher depression score the elderly had, the more they smoked. More depressed elderly showed a significantly smaller BMI compared to the less depressed ones. A negative correlationship existed between the depression score and the elderly's nutrient intakes, especially energy intake which showed a significant negative correlation. There were no significant differences between health anxiety score and nutrient intakes of men. Women who had a higher health anxiety score consumed more energy significantly. The depression score did not affect the elderly's blood biochemical indices. Women who had a low health anxiety score showed a significantly higher HDL-C level.

Objective: This study aimed to summarize and analyze the usage of and the satisfaction levels with combined treatment including Oriental and Western medicine. Methods: We searched studies on the usage of and the satisfaction levels with combined treatment including Oriental and Western medicine over the past 10 yrs (2001-2011) from 3 Korean databases (National Assembly Library, Research Information Service System, and National Discovery for Science Leaders). The reviewers also conducted a summarizing analysis by sampling the literature according to the type of study, study period, region, study subjects, sample size, type of sampling, research method, data analysis, study instruments, main results, etc. Results: When the main results of six studies on combined treatment usage and satisfaction levels were considered together, the most important decisive factor in determining the usage of combined treatment was the illness of the patient, followed by the patient's occupation, sex, age, education, marital status, religion, treatment cost, and treatment results. In addition, the most important factor that determined satisfaction levels with combined treatment was age, followed by education, religion, income, health status, treatment procedures, staff attitude, and cleanliness. Conclusions: Elderly patients with musculoskeletal, cerebro-vascular, and circulatory system illnesses are more likely to prefer combined treatment over independent Oriental or Western treatment and are more likely to request specialized, adjusted medical care.

Survey reports of election opinions consist of numerous cross-tabulations between socio-demographic variables and political opinions including preferred candidates. Since socio-demographic variables are related each other, duplicate interpretations arise. The aim of this study is twofold: The first is to separate the effects of socio variables such as education, occupation and income from the effects of demographic variables such as region, sex and age. The second is the visualization of multiple cross-tabulations in low-dimensional space by extended doubling technique of correspondence analysis. Survey researchers may get some help from this study to present their survey results more lucidly and visually.

Objectives: This study aims to identify the factors associated with colorectal cancer screening behaviors. Methods: The nation-wide representative samples of 2,928 adults aged ${\geq}50$ years for colorectal cancer screening were derived from the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV). This study investigated socio-demographic, health behavioral and contextual factors associated with colorectal cancer screening using descriptive statistics and multivariate logistic regression analysis. Results: In terms of socio-demographic factors, gender, age, marital status, occupation, monthly income, and resident region were significantly different between screening group and non-screening group. Among health behavioral and contextual factors, regular physical checkup, weight control, physical activity, smoking, drinking and having other cancers were significantly different. From the multivariate logistic regression analysis, marital status, education level, regular physical checkup and weight control were associated with colorectal cancer screening behavior. Conclusions: It is necessary to understand the importance of early detection and cancer screening. Appropriate health education and active promotion about the cancer screening should be developed based on the study findings in order to motivate people to have cancer screening. Also, these findings should be reflected in the health policy.
