  • Objectives: This study was performed to identify the level of health literacy and to investigate the relationship between the health literacy and preventive health care use in middle-aged adults in Korea. Methods: A total of 315 adults aged 40 to 64 years living in Seoul participated in the study. Data were collected from December 15-24, 2010 from outpatient hospitals, clinics, workplaces and other locations in the community. Health literacy was measured using the Functional Health Literacy and Self-rated Health Literacy Questionnaires. Preventive health service use was defined as receiving screening (general health checkups, gastric and colorectal cancer, mammogram, and pap smear) and influenza vaccination. Descriptive analysis, t-test, and ANOVA were used. Results: The mean of functional health literacy was 3.87 (score range 0-6) and the self-rated health literacy was 60.08 (score range 16-80). The most difficult items of the self-rated questionnaires were patient educational materials provided by health care providers and medical forms. The most difficult items of functional health literacy were information-based, including nutritional facts and clinical schedules. Association between health literacy and preventive health service use was not found. Conclusions: Further study is necessary with larger samples and with considerations for their education level, age, and preventive health care use.

  • Objectives: The purpose of this study was to evaluate the effects of 12 weeks walking exercise program participation on changes in aging-related hormones concentration in elderly men. Methods: 16 elderly men(above 65 years old) were participated in 12 weeks walking exercise program by group types(exercise group ; n=8 & control group ; n=8), and their aging-related hormones(GH, testosterone and melatonin) levels were assessed before program(0 week) and after program(12 weeks). Regularly walking exercise program(field walking exercise) performed for 12 weeks(3days/week, 60~70min/day, HRR 55~65%). All data were expressed as mean and standard deviation by using SPSS/$PC^+$(ver. 13.0) program, and to evaluate the differences before and after treatment by groups, data were analyzed by paired t-test(a${\leq}$.05) and 2-way ANOVA was performed to examine the differences between groups and within groups by variables. Results and Conclusion: The conclusions obtained from this study were as follows ; In growth hormone. testosterone and melatonin response after 12 weeks exercise was increased significantly in walking exercise group(p<.01; p<.001; p<.001). And in result of 2-way ANOVA analysis for group, exercise, group${\times}$exercise, as compared with the exercise, there is significant difference in all items. Interaction effect of between group and exercise is difference significantly on GH(F=5.915, p<.05), testosterone(F=15.117, p<.01) and melatonin(F=8.131. p<.01) in all groups. We observed a direct relationship(positive improvement) between the regular physical activity and aging-related hormones(growth hormone, testosterone and melatonin concentrations) in elderly men.

  • Objectives: The purpose of this study was to evaluate the female sexual dysfunction of North Korean defector women and to identify related factors. Methods: A total of 110 North Korean defector women who married and lived in South Korean community more than 1 year participated in this study. A self-report questionnaire was used to obtain data. The dependent variable is the Female Sexual Function Index (FSFI). Independent variables were demographic factors (age, education, residential environment, sexual experience(rape), sex knowledge and sex attitude). Data were analyzed using the SPSS for descriptive statistics, t-test, two-way ANOVA, and Multiple Hierarchical Regression. Results: The mean score of sexual function for North Korean defectors was 18.94(SD:5.88). Sexual functioning for North Korean defector women was relatively low, 18.94 in comparison to Rosen's cutoff scores of 26.6. In multiple regression analysis, the sexual function level was significantly higher in elderly, high educational level, stable residential situation, non rape, and conservative sexual attitudes. Conclusions: The results show the status and description of sexual dysfunction in North Korean Women defectors in South Korean community and can be a basic reference for study about sexual dysfunction. However, more study about North Korea Defector Women with sexual dysfunction should be interviewed and evaluated.

  • The Purpose of this study is to determine how Korean and United Sates families manage resourcese. Further, socioeconomic and social psychological determinants of frequency of family resoures management will be investigated for each country. Comparision of results well be made to find similarities and differences between Korea and the U.S. Most studies of family resource management have used urban samples, so this study adds to understanding of another segment of the populations. Family resource management variables, as dependent variables, were measured by asking respondents how often they used a variety of wasys to handle finances and time. Independent variables were : (a) total household income, (b) respondents education, (c) respondents ages, (d) householder size, (e) family adaptability, (f) family cohesion, and (g) interpersonal communications. Data for the Korean sample were collected in rural areas of South Korea during summer 1989, U.S. data were collected in two counties of Illinois. The data used in this study include 473 Korean samples and 301 U.S. families. In both samples, the respondent was the financial manager, the person who usually handled the finances and paid the bills. The data were analyzed by frequencys, t-test, and multiple regression analysis methods. As a results, U.S. respondents tended to engage in family resource management more frequently than Korean respondents. This could be attributed to a longer history of consumer education and financial management education taught in the public schools and through the Cooperative Extension Service in the U.S. Social-psycological variables were significant predictors of frequency of family financial management in both samples. the differences in both samples are that, in Korea, frequency of family financial management increased as household size and educational years increased, however, in the United States, the relationships of these variables were not significant. Some similarities and differences were found in Korea and the U.S. families, and this results represents that interpersonal communications are important determinants, even in different cultures. One hadn, the difference of socio-cultural factors result as the difference of some statisical differences. Findings from this study have important implications for research and education, and can be applicated to study of family resource management in other rural areas.

  • Purpose: This study aimed to investigate the influence of health status and types of health management on depression in middle-aged women. Methods: A convenience sample of 188 participants was recruited from health centers in S city. Using a structured questionnaire, data was collected and analyzed by t-test, ANOVA, Pearson's correlation, and linear regression using SPSS/WIN 23 program. Results: Results of the regression analysis showed that perceived current health status (${\beta}=-0.55$, p<.001), no caregiver (${\beta}=0.47$, p<.001), chronic diseases lasting more than three months (${\beta}=0.36$, p<.001), perceived health status compared to peer group (${\beta}=0.32$, p<.001), walking for health (${\beta}=-0.20$, p=.002), caregiver except family (${\beta}=0.18$, p=.001), and gastrointestinal disease (${\beta}=0.10$, p=.022) influenced depression in middle-aged women. Overall, approximately 69.7% of total variance explained this model (adjusted $R^2=0.678$, F=57.21, p<.001). Conclusion: This study suggests that it is more important to understand the level of perceived health status in middle-aged women. Furthermore, it is necessary to develop programs that include various health management methods and strengthen the health care with the help of families and neighbors in order to manage depression in middle-aged women.

  • The aims of this study were to examine the actual conditions surrounding the purchasing of online game items and Internet cyberspace items by adolescents the propensity of adolescents to consume these items, to determine the difference in the propensity for high and low consumption of these items among adolescents, and to investigate the characteristics of the adolescents who show a high propensity for the consumption of Internet items. The data for this study were collected from 483 adolescent consumers who were middle school and high school students in the city of Bucheon in Gyeonggi Province. The statistical methods used for the data analysis included frequency, percentage, standard deviation, t-test, and one-way ANOVA. The results of the present study can be summarized as follows. The majority(79.5%) of the students surveyed had had the experience of purchasing items. Most students(67.5%) had a rare frequency of buying ($1{\sim}2$ times in a period of 6 months or less). Nearly half (47.9%) of the students spent less than 1000 won per month on the item(s) purchased. Most of the students purchased items with their parents' permission, but 26.6% of the students bought the items without their parents' permission. Most of the characteristics of the items purchased, such as the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, and whether or not they had their parents' permission differed according to gender, grade level, record, and monthly allowance. The level of propensity to consume the items was not high. The propensity of imitation consumption (1.96) was lower than that of impulsive consumption (2.38) and conspicuous consumption (2.45). Most of the buying characteristics, including the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, parents' permission, grade level, and monthly allowance were different between the high and low propensity for consumption groups.

  • Mortar is a masonry product which is matrix of concrete. It consists of binder and fine aggregate and moreover, it is an essential associate in any reinforced structural construction. The strength of mortar is a special concern to the engineer because mortar is responsible to give protection in the outer part of the structure as well as at a brick joint in masonry wall system. The purpose of this research is to investigate the compressive strength and tensile strength of mortar, which are important mechanical properties, by replacing the cement and sand by stone dust. Moreover, to minimize the increasing demand of cement and sand, checking of appropriateness of stone dust as a construction material is necessary to ensure both solid waste minimization and recovery by exchanging stone dust with cement and sand. Stone dust passing by No. 200 sieve, is used as cement replacing material and retained by No. 100 sieve is used for sand replacement. Sand was replaced by stone dust of 15%, 20%, 25%, 30%, 35%, 40%, 45% and 50% by weight of sand while cement was replaced by stone dust of 3%, 5%, and 7% by weight of cement. Test result indicates that, compressive strength of specimen mix with 35% of sand replacing stone dust and 3% of cement replacing stone dust increases 21.33% and 22.76% respectively than the normal mortar specimen at 7 and 28 days while for tensile it increases up to 13.47%. At the end, optimum dose was selected and crack analysis as well as discussion also included.

  • Objective : The subgenual cingulate cortex, a part of default-mode network, has been known to playa key role in the pathophysiology of depression. The previous studies have reported abnormal functional connectivity between the subgenual cingulate cortex and other brain regions in the patients with depression. The goal of this shldy was to explore the resting-state functional connectivity of the subgenual cingulate cortex between the patients with depression and healthy subjects. Methods : Twenty patients with major depression and age- and sex-matched 20 healthy subjects underwent 5-minute resting state fMRI scans. The functional connectivity map in each subject was acquired using seed-based correlation analysis with the seed located in the subgenual cingulate cortex (Talairach coordinates; x=-10, y=5, z=-10). The functional connectivity maps were calculated using AFNI and compared between the patient and healthy subject group via two-sample T-test using 3dttest++ in AFNI package. Results : Functional connectivity was decreased between the subgenual cingulate cortex and both sides of fusiform gyrus in depressed subjects. Connectivity was also decreased between the subgenual cingulate cortex and the left cerebellum in the patient group. There was no correlation between the severity of depression and the degree of functional connectivity between the subgenual cingulate cortex and the regions showing decreased functional connectivity. Conclusion : Decreased resting-state functional connectivity between the subgenual cingulate cortex and both sides of fusiform gyrus, and decreased connectivity between the subgenual cingulate cortex and the left cerebellum found in the patients with major depression in comparison to the healthy subjects might be related to abnormal emotional and cognitive processing of depressed patients.

  • Purpose: The purpose of this study was to determine whether Selection, Optimization and Compensation (SOC) Strategy mediated the relationship between job stress and health promoting behaviors among nurses. Methods: A descriptive causal relationship research design was used. 245 subjects recruited from the five general hospitals, which have over 500 beds in Seoul and Kyunggi-do, participated in the study by completing a survey which included questions about SOC strategy, job stress and health promoting behaviors. t-test, ANOVA, Pearson's correlation coefficient and multiple regression were used to analyze the data. SPSS/WIN 20.0 was used for all analysis. Results: The mean job stress score was 47.89; mean SOC strategy score was .71. 'Spiritual development' was the highest reported health promoting behavior with a mean of 3.57. Job stress was significantly and negatively related to health promoting behaviors. The result showed that all the mediating paths of SOC strategy were significant. The partial mediating model showed high goodness of fit demonstrating that the model was outstanding. Conclusion: SOC strategy mediated the relationship between job stress and health promoting behaviors. Applying better SOC strategies among nurses will increase flexibility in responding to job stress and will also better perform health promoting behaviors.

  • Background: One of the main causes of delay in diagnosis of oral cancer is lack of awareness about aetiology and symptoms among the general population. The aim of this study was to assess the knowledge and practice of patients regarding oral cancer and their attitude towards tobacco cessation. Materials and Methods: This study was carried out in Isfahan-Iran in 2014. A 29-item self-administrated questionnaire was designed and piloted and distributed to patients attending dental clinics. Questions were focused on awareness about oral cancer risk factors, signs and symptoms, places in the mouth which are more susceptible and attitude toward tobacco cessation. Chi-square, T-test, ANOVA and logistic regression tests were used for statistical analysis. Results: A total of 546 valid completed questionnaires were obtained. The mean knowledge score of patients was 4.1(${\pm}2.7$) out of 13. Some 80% of patients did not know about early manifestations of oral cancer. Only 18% knew the most likely sites of oral cancer. Only 43.1% and 65.2% of patients reported alcohol and tobacco consumption as the main risk factors but they had a fair knowledge about other risk factors. There was no significant difference in Knowledge level between patients regarding their sex, educational levels and age. Most patents (90%) expected their dentists to warn them about the harmful effects of smoking and showed willingness to quit if recommended. Conclusions: Knowledge about oral cancer was found to be quite low. It seems necessary to increase the level of public awareness using educational programs with cooperation of dentists in tobacco cessation programs.
