This longitudinal study examined picture book reading practices with very young children and its influence on early intellectual development. The home picture book reading activities of 322 infants and their mothers were assessed by questionnaire every 6 months from 18 months till 42 months of age. Infants' IQ was measured with Korean-Wechsler Preschool and Primary Scale of Intelligence(Park et al., 1996) at 42 months. Results showed that monthly book expense (r=.28, p<.01) and infants' asking for reading (r=.14, p<.05) at 18 months were positively correlated with IQ at 42 months. Reading time between 24 and 42 months correlated positively with IQ(r=.17~.34, p<.01). These results reveal the importance of early book environment and actual reading time in the intellectual development of very young children.

Purpose: The purpose of this study was to identify the relationship of pain, fatigue, and illness duration in elderly women with osteoarthritis. Methods: The subjects of the study were one hundred and thirty five elderly women (age over 65years) who have an osteoarthritis. Data were gathered from September 2002 to June 2005 using a questionnaire. Data were analyzed with the SPSS Win 11.0 using descriptive statistics, t-test, ANOVA and Pearson's correlation coefficient. Results: Pain in the elderly women with osteoarthritis correlated with fatigue (r= .447, p= .00). Pain showed a significantly positive correlation to illness duration (r= .197, p= .02). Fatigue showed a significantly positive correlation to illness duration (r= .213, p= .01). Conclusion: It is suggested that we need to develop the pain and fatigue control program considering illness duration should be provided for elderly women with osteoarthritis.

Cracks on the surface of latex-modified concrete using ready mix concrete (R-LMC) are attributable to its sensitivity to air temperature, relative humidity and wind velocity. Insufficient curing under the windy condition causes plastic shrinkage cracks. The cracked areas should be replaced to prevent development of larger cracks. This paper investigated how the vibration resulted from crushing concrete for replacement of the partial cracked area affects bond strength of R-LMC at early age. To analyze bond strength of R-LMC, the commercial Finite Element (FE) program, ABAQUS Standard/Implicit version 6.12 was used, and bond strength was tested by ASTM C1583-04. The real vibration was applied to this FE model using an acceleration measurement equipment.

Purpose: This study aimed to identify the factors influencing positive subjective health awareness of middle school-age multicultural adolescents in Korea. Methods: This study used data from the fourth to sixth waves of the Multicultural Adolescents Panel Study conducted by the National Youth Policy Institute. In this study, a panel logit model analysis was performed using the Eviews 8.0 program (p<.050). Results: Socioeconomic status (r=.02, t=2.13, p=.033), body satisfaction (r=.71, t=1.97, p=.048), and depression (r=-.74, t=2.35, p=.018) influenced positive subjective health awareness in multicultural adolescents. When multicultural characteristics were entered into a statistical model with environmental and personal characteristics, multicultural characteristics did not have a significant influence on positive subjective health awareness. Conclusion: Environmental, personal, and multicultural characteristics were related to positive subjective health awareness in multicultural adolescents; thus, an integrated approach considering those variables is recommended. Nursing interventions and educational programs are needed to improve the psychological status of multicultural adolescents and reduce prejudice about them. In addition, nurses need to be sensitive to multicultural characteristics and the developmental characteristics of multicultural adolescents.

Sister chromatid exchanges(SCE) in peripheral lymphocytes is recently used as a biomarker for increased cytogenetic damage in smokers. The purpose of the investigation was to determine if there were any relationships between dietary factors and their DNA damage as measured by SCE test in a group of 62 male cigarette smokers and 36 non-smokers. As expected, smokers as compared with non-smokers had high SCE levels (10.59$\pm$0.21 versus 9.23$\pm$0.17 SCE/lymphocytes ; p<0.05). No significant relationships were observed between SCEs and age in smokers and non-smokers. In smokers, SCEs were negatively correlated with egg frequency score(r=-0.336) and total food frequency scores(r=-0.283). In non-smokers, SCEs were positively correlated with white vegetable frequency score(r=0.333) and instant food frequency score(r=0.382). There was a positive association between SCEs and the history of coffee intake of smokers(r=0.318). SCE frequency was not influenced by any other dietary factors considered ; dietary diversity and quality scores, alcohol consumption, use of processed foods and intake of burned food. No significant relationships were found between SCEs and serum cholesterol or other hematological parameters of the subjects. These results indicate that increased egg frequency score, total food frequency score which reflects dietary quality, and decreased coffee intake may reduce cancer risk by preventing smoking-induced DNA damage as reflected by sister chromatid exchanges in human lymphocytes.

The purpose of this paper is to present an optimization scheme that aims at minimizing the expected cost per unittime. This study considers a linear connected-(r, s)-ouI-of-(m, n):f lattice system whose components are orderedlike the elements of a linear (m, n)-matrix. We assume that all components are in the state 1 (operating) or 0(failed) and identical and s-independent. The system fails whenever at least one connected (r, s)-submatrix offailed components occurs. To find the optimal threshold of maintenance intervention, we use a simulatedannealing(SA) algorithm for the cost optimization procedure. The expected cost per unit time is obtained byMonte Carlo simulation. We also has made sensitivity analysis to the different cost parameters. In this study,utility maintenance model is constructed so that minimize the expense under full equipment policy throughcomparison for the full equipment policy and preventive maintenance policy. The full equipment cycle and unitcost rate are acquired by simulated annealing algorithm. The SA algorithm is appeared to converge fast inmulti-component system that is suitable to optimization decision problem.

This paper empirically examines various personal characteristics and preferences of HRM (Human Resorce Mamagement) systems using data from 968 R&D professionals in 9 private R&D organizations. It identifies different patterns of reward and career development needs associated with 4 types of R&D professionals, who are categorized by personal characteristics: personality and attitude. A productive leader type shows active personal traits (which encompass high scores of need for achievement, risk-taking propensity, tolerance for ambiguity, and self-efficacy) and positive attitudes (which include high scores of job satisfaction, organizational commitment, and low scores of turnover intention), while a cynical bystander type exhibits passive personal traits and negative attitudes toward a job. A passive adapter, who has passive personal characteristics but positive attitudes, and a frustrated champion, who is active in personality but negative in current job attitude, lie in between them. The results reveal that: 1) These four different types of R&D professionals show differences in their education, age and tenure level, and technical performance. 2) They have different career orientations and problem solving styles. 3) They also exhibit different preferences in performance appraisal criteria and rater, and reward structures. Based on these findings, this study suggests a contingent type of human resource management in terms of selection and staffing of R&D professionals, performance appraisal, incentive systems, and career development plans.

Purpose: This study aimed to examine factors affecting suicidal ideation among female late adolescents from a Korean rural province. Methods: A descriptive cross-sectional design involving self-reported questionnaires was used. The data were collected from female adolescents aged 18 to 22 years, from high schools, universities, churches, and local community centers. The sample consisted of 197 female late adolescents from three rural areas in Korea. The Center for Epidemiological Studies-Depression Scale and the Suicidal Ideation Scale were used to measure depression and suicidal ideation, respectively. Results: Suicidal ideation was correlated with having a specific suicide plan (r=.65, p<.001), depression (r=.39, p<.001), subjective well-being (r=-.46, p<.001), ever experienced violence (r=.15, p=.029), and age (r=-.21, p=.003). Factors affecting suicidal ideation among rural female adolescents were having a specific suicide plan (β=.56, p<.001), subjective well-being (β=-.23, p=.001), and suicide of a close person (β=.12, p=.035). These factors explained 48.0% of the variance in suicidal ideation (F=37.62, p<.001). Conclusion: This study demonstrated that affective factors and personal experiences regarding suicide were critical indicators for suicidal ideation among female late adolescents. These factors should be managed and tailored nursing interventions should be offered to prevent suicide and to enhance the psychiatric health status of female late adolescents.

Purpose: This study was done to identify the relationship of perceived health status, leisure satisfaction, loneliness and life satisfaction and to identify predictors of life satisfaction for elders. Method: The research design for this study was a descriptive survey design using a convenience sample. Data collection was done using self-report questionnaires with 297 elders from 6 community health practitioner posts. Data were analyzed using ANOVA, t-test, Pearson correlation coefficients and hierarchical multiple regression with the SPSS Win 18.0 Program. Results: Life satisfaction had significant negative correlations with age (r=-.31, p<.001) and loneliness (r=-.73, p<.001), and positive correlations with monthly spending money (r=.44, p<.001), health status (r=.63, p<.001), and leisure satisfaction (r=.62, p<.001). The explained variance for life satisfaction was 72%. Variables of monthly spending money, health status, leisure satisfaction, and loneliness significantly predicted the degree on life satisfaction of these elders. Conclusion: Findings of this study provide a comprehensive understanding of life satisfaction and related factors for elders in Korea. However, further studies with a larger random sample and more detailed research design are necessary.
