Purpose: This study was designed to assess the degree of psychological well-being, perceived health status, and health promoting behavior of clinical nurses, and to identify correlations between variables. Methods: Participants were 194 nurses working at S hospital, Seoul and data were analyzed using descriptive statistics, ANOVA, Duncan's test, Pearson correlation coefficient, and multiple regressions. Results: Mean scores were 3.45 (5 point scale) for psychological well-being, 2.82(4 point scale) for perceived health status, and 2.30(4 point scale) for health promoting behavior. Psychological well-being correlated positively with perceived health status (r=.34, p<.001). Perceived health status showed a positive correlation with health promoting behavior (r=.30, p<.001). There was a positive correlation between psychological well-being and health promoting behavior (r=.52, p<.001). Personal growth(t=2.85, p=.005), purpose in life (t=2.30, p=.023) among subscales of psychological well-being, and perceived health status (t=2.13, p=.034) had a significant influence on health promoting behavior. These combinations explained 32.1% of health promoting behavior (F=12.58, p<.001). Conclusion: The results of this study suggest strategies to improve health promoting behavior by enhancing psychological well-being of nurses. Furthermore, a study to identify the effects of developed and applied psychological well-being promotion program should be conducted.

As the life expectancy of human beings gets longer and our society changes into highly competitive arena, the implementation of online adult learning is growing, and therefore the learners in self-regulated scaffolding learning environments is becoming an important topic. This study is to investigate the main effects of scaffolding and self-regulation and the interaction effect on discussion participation and comprehension in online learning environments. To do this, ninety-nine adults taking online learning courses with the open university in Korea were investigated. Adult learners were divided into one of the four groups (no scaffolding, conceptual, strategic, and conceptual and strategic scaffoldings). Regarding self-regulation, learners were divided into two groups (low and high self-regulated) based on the mean score of subjective report of self-regulated learning. The results are as follows : First, 'strategic scaffolding' is more effective than 'conceptual scaffolding' in discussion participation (F=2.772, p < .05) and comprehension test (F=7.156, p < .05). Second, high self-regulated learners more actively participate than low self-regulated learners in discussion (F=6.230, p < .05), and achieve higher scores (F=4.863, p < .05). Third, there is no interaction effect between scaffolding strategies and the level of self-regulation. The theoretical and practical implications of these findings are discussed.

Purpose Phenylketonuria is an inborn error of metabolism, which is inherited as an autosomal recessive trait. PKU is resulting from deficiency of phenylalanine hydroxylase. PAH gene spans about 90 kb on chromosome 12q and comprises 13 exons. In order to define the genetic basis of PKU and the frequencies and distribution of PAH mutations in the Korean population, we analyzed PAH gene in independent 80 patients with PKU. Methods All 13 exons including exon-intron boundaries and 2 kb of 5' upstream region of the PAH gene were analyzed by PCR-direct sequencing methods. Results PAH gene analysis revealed 39 different mutations including 10 novel mutations. The novel mutations consisted of 9 missense mutations (P69S, G103S, N207D, T278S, P281A, L293M, G332V, S391I and A447P) and a novel splice site variant (IVS10-3C>G). R243Q, IVS4-1G>A, and E6-96A>G were the most relevant mutations and they accounted in the whole for 38% of the mutant alleles identified in this study. We also observed that. $BH_4$ responsibility was. associated with genotype of R241C, R53H and R408Q. Conc1ustion Our present study with 80 participants extends the previous results to more comprehensive understanding of PAH allele distribution and frequency in Koreans. Although Korean mutation profile of PAH is similar to those of the nearest oriental populations (Japanese, Chinese, and Taiwanese), several different characteristic features are revealed. The characterization of the genotype-phenotype relationship was also performed. Our data would be very useful information for diagnosis, genetic counseling and planning of dietary and therapeutic strategies in Korean PAH patients.

BACKGROUND/OBJECTIVES: Skipping breakfast is prevalent in young adult women. This study examined the psychosocial factors and eating behaviors according to the breakfast frequency among female university students. SUBJECTS/METHODS: The subjects were female university students in Seoul, South Korea. A survey was done, and the data from 291 students were analyzed. The subjects were categorized into a high breakfast group (HBG) and low breakfast group (LBG). Analysis of covariance and multiple linear regression were mainly used in data analysis. RESULTS: The subjects had breakfast 3.6 days/week on average. The HBG (47.4%) and the LBG (52.6%) differed significantly in breakfast status, including place, people eating together, breakfast menu, and breakfast preparers (P < 0.001). The HBG agreed more strongly with the advantages of breakfast than the LBG (P < 0.001). The disadvantages/barriers of breakfast were stronger in the LBG (P < 0.001). The HBG felt more confidence in having breakfast (P < 0.001) and confidence in general eating behaviors (P < 0.05). The two groups also differed in the subjective norms from parents/professionals (P < 0.001) and siblings/friends (P < 0.01). The HBG showed desirable eating behaviors more frequently (P < 0.001) and undesirable eating behaviors less frequently (P < 0.001). Multiple regression showed that the following were significantly related to the breakfast frequency, explaining 57.3% of the variance: self-efficacy regarding having breakfast (P < 0.001), perceived barriers of breakfast (no appetite/habit/indigestion, P < 0.001), desirable and undesirable eating behaviors (P < 0.01), subjective norms from parents/professionals (P < 0.05), and perceived barriers due to lack of time/preparation difficulties (P < 0.05). CONCLUSIONS: Psychosocial factors and eating behaviors were significantly related to the breakfast frequency. Nutrition education might include strategies to increase self-efficacy for breakfast, modify the beliefs, particularly the disadvantages/barriers of breakfast, adopt desirable eating behaviors, and elicit support from significant others.

Purpose: This study aims to identify differences in breast self-examination (BSE) performance and influencing factors between woman-groups under and over 45 years old. Methods: The subjects were 152 women aged from 35 to 65, who were recruited through convenient sampling in a metropolitan city. They were divided into two groups: under and over 45 years old. The data were collected using self-reporting questionnaires and analyzed by $x^2$ test, t-test, Pearson's correlation coefficient, and stepwise multiple regression. Results: Experience of BSE education ($x^2$=4.68, p=.030), BSE performance ($x^2$=20.12, p<.001), confidence (t=-2.97, p=.003), and self-efficacy (t=-2.44, p=.016) were significantly higher in the group over 45 years (the older group) than the one under 45 years (the younger group). Self-efficacy (${\beta}$=.346, p=.004) and susceptibility (${\beta}$=.238, p=.002) were 17.6% of the variance in the younger group's BSE performance. On the other hand, significantly influencing factors on the older group's BSE performance were self-efficacy (${\beta}$=.500, p<.001) and BSE education (${\beta}$=.217, p<.001), which accounted for 25% of the variance in the BSE performance. Conclusion: We conclude that differentiated strategies of considering age should be established in nursing intervention to detect breast cancer early.

Purpose: Infertile women experience various physical, psychological, and relational problems that affect their infertility-related quality of life (QoL). This study investigated infertile women's infertility-related QoL with the goal of identifying how it is influenced by fatigue, depression, and marital intimacy. Methods: A sample of 140 infertile women was surveyed in a cross-sectional study. Data were collected from February to April 2018 using self-report structured questionnaires at three infertility clinics located in Jeonju, Korea. Data were analyzed using the independent t-test, analysis of variance, Pearson correlation coefficients, and stepwise multiple regression analysis in SPSS for Windows version 25.0. The subjects agreed to complete a face-to-face interview, including administration of the Fatigue Severity Scale, Depression Anxiety Stress Scale-21, Marital Intimacy Scale, and the Fertility Quality of Life tool. Results: The mean age of the participants was 35.6±4.3 years. Infertility-related QoL was negatively correlated with fatigue (r=-.42, p<.001) and depression (r=-.56, p<.001), and positively correlated with marital intimacy (r=.30, p<.001). Multiple regression analysis showed that depression (β=-0.44, p<.001), fatigue (β=-0.27, p<.001), and husband's attitude (β=-0.19, p=.007) had significant effects on the QoL of infertile women, accounting for 40.5% of the variance in infertility-related QoL. Conclusion: The study provides insights into how infertile women's infertility-related QoL was influenced by depression, fatigue, and their husbands' attitudes regarding infertility treatment. To improve infertile women's infertility-related QoL, healthcare providers should consider developing strategies to decrease depression and fatigue in infertile women and to address their husbands' attitudes.
