This study was conducted to identify the factors influencing toothbrushing behaviors of elementary school students by adding the variable of 'self-efficacy' to the behavioral model based on the theory of planned behavior. To collect the data for an analysis, the self-administered questionnaire was distributed to 443 students in 4th to 6th grades of elementary school placed in Inchon Metropolitan City. The statistical package of PASW 18.0 was employed for the analysis. Results of the analysis revealed that the toothbrushing intention was explained by the subjective norm (${\beta}=0.343$), the self-efficacy (${\beta}=0.171$), the perceived behavioral control (${\beta}=0.163$), and the attitude toward the tooth-brushing behavior (${\beta}=0.135$). The toothbrushing behavior was explained by the toothbrushing intention (${\beta}=0.355$) and the self-efficacy (${\beta}=0.113$). The synthesis of such results suggested that both parents and teachers in school who would be influential to students should guide elementary school students to be habituated to the right toothbrushing. Also it was estimated that the students should understand the importance of toothbrushing through proper oral health education, and they should also become confident in spontaneous toothbrushing by providing them with an environment that could help them practicing the toothbrushing easily.

Nursing process is an essential part for nursing practice. Nursing faculty members must focus on the clinical application for students and try to identify the possible problems that students might face in the fields. The purpose of this study is to examine the actual condition of nursing process education in curricula and to investigate the response of students in clinical experience of nursing process. From 462 students in the 6 associate programs(ADN) and the 6 baccalaureate programs (BSN) data was collected by questionnaire. The results were as followed. 1. Seven programs (58.3%) opened the nursing process in mainly sophomore (BSN) or freshman(ADN). If not opened, the nursing process was taught at the major subjects(espcially fundamental nursing or adult nursing). 2. All Students responded they we supposed to use nursing process in preparing the case report. The majority(94.6%) used NANDA lists for nursing diagnosis and 55.7% of subjects consulted the Korean terms by KNA when translating. The tutors for nursing process in clinical settings were the professor in charge of the subject (68.6) or clinical instructors (48.1%) , assistants(34%). 3. The problems in clinical application that students experienced consisted of 17 items and the mean was 2.27. The biggest problem was 'the lack of the model for RN of applying the nursing process in clinical settings'(2.97). Next the big problem was 'the lack of the competency for implementing the established nursing plans'(2.69). All items were significantly different according to the level of educational programs(ADN or BSN). ADN students had more problems in applying the each step of nursing process and BSN students perceived the NANDA as a guidance of nursing diagnosis and the inconsistency of advices from several instructors or practicum to be mere problematic. 4. The mean of merits after application of nursing process was relatively fair (2.82). The best merit was 'they can identify nursing problems more exactly'(3.07). The second high merit was 'they can study the rational of nursing action' (3.03). BSN than ADN and the subjects of second year than of one year in clinical experience perceived the use of nursing process to be better. Based on this results we need to enforce the application of nursing diagnosis in the class. The use of sample cases can be the efficient method. Students can identify the possible health problems for patient from the cases in imaginary world and discuss them each other. Also we can use the discussion session after practice every other day or as needed. All this is on the good interaction between tutor and student. We must consider to have enough time for student to seize the essence of the nursing process.

There is recent recognition that the approach toward family members is crucial for understanding problems in multi-cultural families by emerging from typical approach focused on migrant women. While researches have reported serious conflicts and adaptation problems from cultural difference between parent-in-law and foreign daughter-in-law, cultural stress of parent-in-law has not been systematically examined. The purpose of this study was to develop and validate a scale to measure acculturation stress of parent-in-law who have a foreign daughter-in-law. The sample consisted of 266 parents-in-law from three provinces of South Korea. Initially, 16 items were generated based on the existing scale of acculturation stress and they are tested by item-analysis through the descriptive and correlational analysis. An exploratory factor analysis was conducted to investigate the factor structure of the scale and a confirmatory factor analysis was used to validate the scale. By item-analysis, five items were deleted from initial scale items because of redundancy. Findings from an exploratory factor analysis provided the evidence that the scale consists of three factors which are the perception of prejudice and discrimination, conflicts from different cultural value, and daily discomfort. Cronbach's ${\alpha}$ for the scale is 0.86. Multiple fit indices from confirmatory factor analysis indicated that the hypothesized three-factor model for acculturation stress achieved a good fit with the data. Results showed the evidence for the reliability and validity of the scale for acculturation stress of the parent-in-law who have foreign daughter-in-law. The scale would have potential effects for assessing psychological stress for parent-in-law in research and clinical practice. Further implications and limitation of the study and suggestions for future studies were discussed.

Background: More than half of cases for advanced non-small-cell lung cancer (NSCLC) occur in elderly patients with a median age at diagnosis of 70 years. The aim of our study was to examine the clinical features and prognostic factors contributing to mortality in elderly patients with advanced NSCLC. Methods: Following a retrospective review of clinical data, 122 patients aged 70 years and over with a histopathological diagnosis of locally advanced (stage IIIB, n=32) and metastatic (stage IV, n=90) NSCLC between 2005 and 2011 were enrolled. Results: The median age was 76 years (interquartile range, [IQR], 72-80 years), and 85 (70%) patients were male. Fifty-seven (46%) patients had never smoked, and 17 (19%) were in a malnourished state with a body mass index (BMI) of <$18.5kg/m^2$. The initial treatments included chemotherapy (40%) and radiotherapy (7%), but 57% of the patients received supportive care only. The 1-year survival rate was 32%, and the 3-year survival rate was 4%, with a median survival duration of 6.2 months (IQR, 2.5-15.3 months). Male gender (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.3-3.9; p=0.005), low BMI (HR, 2.3; 95% CI, 1.3-3.9; p=0.004), and supportive care only (HR, 1.9; 95% CI, 1.2-2.9; p=0.007) were independent predictors of shorter survival based on a Cox proportional hazards model. Conclusion: Elderly patients with advanced NSCLC had a poor prognosis, particularly male patients, those with a low BMI, and those who received supportive care only.

The purpose of the present study is first to refine the mathematical material models for moisture and temperature distributions in early-age concrete and then to incorporate those models into finite element procedure. The three dimensional finite element program developed in the present study can determine the degree of hydration, temperature and moisture distribution in hardening concrete. It is assumed that temperature and humidity fields are fully uncoupled and only the degree of hydration is coupled with two state variables. Mathematical formulation of degree of hydration Is based on the combination of three rate functions of reaction. The effect of moisture condition as well as temperature on the rate of reaction is considered in the degree of hydration model. In moisture transfer, diffusion coefficient is strongly dependent on the moisture content in pore system. Many existing models describe this phenomenon according to the composition of mixture, especially water to cement ratio, but do not consider the age dependency. Microstructure is changing with the hydration and thus transport coefficients at early ages are significantly higher because the pore structure in the cement matrix is more open. The moisture capacity and sink are derived from age-dependent desorption isotherm. Prediction of a moisture sink due to the hydration process, i.e. self-desiccation, is related to autogenous shrinkage, which may cause early-age cracking in high strength and high performance concrete. The realistic models and finite element program developed in this study provide fairly good results on the temperature and moisture distribution for early-age concrete and correlate very well with actual test data.

This study investigated the perception of beauty-agriculture convergence industry for businesses in senary industries in Jeju Special Self-governing Province. Currently this area is in the stage right before the suggestion of a convergence-based win-win industrial development model. The ultimate goal is to provide basic data to beauty-agriculture convergence industries. Agricultural products are used as main ingredients in the cosmetics industry and recently, farmers have been focusing on certain areas of the beauty industry, such as the internal production of beauty products and the attraction of customers. According to a comparative analysis on the beauty-agriculture convergence industry between employees and non-employees, a statistically significant difference was found in the following: Possibility of creating high profits, personal interest in the beauty industry and the possibility of utilizing natural resources. In terms of the reasons for beauty-agriculture convergence industry development potential such as added value, leading industry, product competitiveness, aesthetic lifestyle and market size, as well, a significant difference was found. In the perception of the necessity of government supports such as financing, facilities, technology, education and PR marketing, no significant difference was observed. Since creative and diverse contents are needed for beauty-agriculture convergence, high-quality technical support and continuous education are essential. Therefore, diverse government supports including funds and facilities are needed.

Objectives : The purpose of this study is analyzing the current research methodology of pharmacopucture for the treatment of animal cancer models. Methods : Four electronic databases were searched for animal studies published from January 2000 to September 2014 onward using these search terms "cancer, anticancer, pharmacopuncture, beevenom". Selected articles were described about animal cancer models. The methods used to induce cancer and the outcome measures used to assess the effects of pharmacopuncture on animal cancer models were analyzed. Results : 37 articles were included. For producing animal cancer models BALB/C mice(n=22) and C57BL/6 mice(n=17) were selected. And intravenous injection of B16-F10 melanoma cells into tail vein(n=14) or intraperitoneal injection of sarcoma-180 cells(n=14) were frequently used to induce cancer. Various pharmacopunctures were injected into acupoints $CV_{12}(n=19)$, $ST_{36}(n=8)$, $BL_{18}(n=8)$ or peritoneal cavity(n=6), tumor site(n=2), tail vein(n=2). Outcome measures were categorized into anti-cancer, anti-metastasis, general condition, cytotoxicity, immune response, toxicity. Median Survival Time(MST) and increase of life span(ILS)(n=26) was frequently used for evaluating anti-cancer effects. And pulmonary colonization assay(n=13) was frequently used for evaluating anti-metastasis effects Conclusions : Based on these data, further research would be needed to ascertain the effectiveness of pharmacopuncture for treating cancer and broaden the range of clinical applications.

This study was done to describe health promoting lifestyle and determine affecting factors in elderly based on the Heath Promotion Model by Pender. Cognitive-perceptual factors that were included in this study were self-efficacy and hardiness. Modifying factors were demographic characteristics (sex, age, partner, previous illness, education level. income and religion). The specific purpose of this study was to examine the relationships of self-efficacy, hardiness and the demographic chasteristics to health promoting lifestyle and to determine causal factors affecting the elderly. The subjects were a volunteer sample of 98 elderly in one city in? The instruments for this study were Health Promoting Lifestyle Profile(47items, 4scale), Health Related Hardiness Scale(22i1ems, 6scale), general Self-Efficacy Scale(13i1ems, 5scale). Frequency, percentage, t-test, ANOVA, Pearson's correlation coefficient and Stepwise Multiple regression technique with SAS program were used to analyse the data. The Results of the study are as follows : 1) The average item score for the health promoting lifestyle was 2.63, the highest score on the subscales was interpersonal support (M=3.3), followed by self-actulization(M=2.9), nutrition(M=2.8), stress management(M=2.7), health responsibility(M=2.1) with the lowest bring exercise(M=2.0) 2) A significant difference between education level, income, religion and health promoting lifestyle were found. 3) All of the subscales on health promoting lifestyle were positively related to total hardiness (r=0.330, p<0.001). The hardiness subscale of control was positively related to self-actulization(r=0.276, p<0.01), and commitment was positively related to self-actualization(r=0.315, p<0.001), exercise /nutrition(r=0.245, p<0.01), interpersonal support(r=0.278, p<0.01), stress management(r=0.250, p<0.01). Challenge was positively related to self-actualization(r=0.315, p<0.001), exercise /nutrition(r=0.245, p<0.01). There was no significant correlation between self-efficacy and all of the subscales of health promoting lifestyle. Self-efficacy showed a significant correlation only with control(r=0.469, p<0.001), comittment(r=0.507, p<0.001), challenge (r=0.489, p< 0.001). 4) Comittment, self-efficacy and income explained 25.01% of the variance for the total health promoting lifestyle. The results of this study show that commitment, self efficacy and income predicted the health promoting lifestyle of the elderly. So health promoting programs that increase commitement and self-efficacy should be developed to promote a healthy lifestyle of the elderly, especially those who have low income.

Nowadays various information devices using electronic technology has been released. And these digital devices will be continuously developed to make a satisfaction of customer's needs. So digital device will support network service using communication technology, so users will use the internet service anywhere, anytime. Also the networked device which is used in ubiquitous computing environment should be evaluated by new evaluation framework. Therefore previous usability evaluation framework need to reflect the characteristics of ubiquitous computing. However most of pervious research about ubiquitous computing was about conceptual issues like rules and characteristics of ubiquitous computing, so the research of usability testing and evaluation method for ubiquitous computing is rarely conducted. This research's purpose is developing the evaluation framework for ubiquitous computing device and usability model for ubiquitous computing. To develop the evaluation framework, we collect the evaluation indexes which have need used in GUI evaluation And we extract evaluation indexes for ubiquitous computing based on literature review.

The purpose of this study was to investigate the influence of the factors such as self-esteem, social supports, socio-economic status of parents, degree of disability in child, stress coping, religion, and sports.exercise on the qualities of lives in mothers with disabled children. Data were collect from 45 institutions(schools from kindergarten to senior-high, special education institutes, and social welfare institutions) by self-report questionnaire, and the subjects of the study were 386 mothers in Seoul whose children were attending the schools or institutions. Findings according to socio-demographic variables are as follows: 1. Mothers with disabled children in this study thought their quality of life as average degree. 2. The younger the mothers and children, the higher the quality of life was. 3. The higher the educational level and monthly income, the higher the quality of life was. 4. There was no statistically significant difference between the existence and nonexistence of spouse, and between the existence and nonexistence of religion as well. Findings analyzed by multiple regression are as follows: 1. Among 7 independent variables 'self-esteem'(${\beta}$=.49, p<.001), 'social supports'(${\beta}$=.15, p<.01), and 'socio-economic status'(${\beta}$=.11, p<.05) were found to be statistically significant in quality of life in mothers, while the rests were found not significant. 2. 'Self-esteem' was found to be the most influencing variable, meaning that the psychological factor such as self-esteem is more important than environmental factors in qualities of lives in mothers. 3. The total amount of explanation of the model was Adjusted R square=.301, so that it can be said about 30% can be explained among total variance of the qualities of lives in mothers with disabled children. Conclusions and recommendations based on the results above are: First, it is strongly recommended to conduct programs promoting self-esteem in mothers with disabled children, and to include 'self-esteem' hereafter in the studies related to qualities of lives in mothers with disabled children. Second, comprehensive and practical countermeasures should to be formulated to back up expenses for education and medical care, purchasing relative tools and equipments, plus helping to find jobs.
