The purpose of this study is to examine the differences in psychological adjustment among university students according to their parents' divorce status and their parents' conflict. Specifically, students who have not-divorced parents were subdivided into two groups: those who have with a high degree of conflict and with a low degree of conflict. The results were as follows. First, the degree of the marital conflict from the divorced parents is higher than the one of the marital conflict from the parents not divorced. Second, the group who has the parents with a high level of marital conflict went through the highest difficulties among 3 groups at all variables without the parent-child relationship. Therefore, this study suggests that marital conflict is more closely related to psychological adjustment of children than parental divorce itself.

Objectives: Cigarette smoking is a modifiable risk factor for cardiovascular disease. Bilirubin is a potent antioxidant and its concentration decreases in smokers. However, studies about the association between cigarette smoking and bilirubin are scarce and most are limited to total bilirubin. Additionally, bilirubin is highly related to hemoglobin. Therefore, this study evaluates the association between bilirubin subtypes and cigarette smoking in healthy Korean men independently of hemoglobin. Methods: This study included 48 040 Korean men aged 30 to 87 years who visited the Korea Medical Institute for routine health examinations from January to December, 2007. The association of smoking with total, direct, and indirect bilirubin was assessed by logistic regression analysis taking into consideration differences in subjects and smoking characteristics. Results: Current smokers had lower bilirubin concentrations than never-smokers and ex-smokers. Smoking amount and duration were inversely significantly associated with total, direct, and indirect bilirubin. In a multivariable adjusted model, compared to never-smokers, the odds ratios (ORs) and 95% confidence intervals (CIs) of current smokers with the highest number of pack-years were 1.7 (1.6 to 1.9) for total, 1.5 (1.4 to 1.6) for direct, and 1.7 (1.6 to 1.9) for indirect bilirubin. After further adjustment for hemoglobin, this association became stronger (OR [95% CI], 2.1 [1.9 to 2.2] for total; 1.9 [1.8 to 2.0] for direct; 2.0 [1.9 to 2.2] for indirect bilirubin). Conclusions: In this study, bilirubin subtypes are inversely associated with smoking status, smoking amount, and smoking duration in healthy Korean men independently of hemoglobin. Further studies are needed to investigate this association in healthy Korean women.

Objectives: The aim of this study was to investigate the effectiveness of a hospital-based smoking cessation intervention for increasing continuous abstinence rate from smoking in patients with cerebral infarction. Methods: One-hundred and two smokers with cerebral infarction who decided to quit smoking were enrolled in the smoking cessation intervention from December 2012 to February 2015. The smokers underwent six consecutive times of individual intervention with nurse specialist on smoking cessation including education on behavioral modification, counseling for withdrawal symptoms, and anti-smoking advice over a 12-month period. Results: Among the total participants, the continuous abstinence rate from smoking changed from 79.4% at 1 month to 60.8% at 12 months after discharge. The continuous abstinence rate from smoking after 12 months was 88.5% in participants who completed the entire program (6 times), while 51.3% in participants who did not complete the entire program (${\leq}5$ times) (P=0.001). After adjustment for general and smoking-related characteristics, complete implementation of hospital-based smoking cessation intervention was significantly associated with continuous abstinence from smoking after 12 months (odds ratio: 5.93; 95% confidence interval: 1.45-24.22). Conclusions: The hospital-based smoking cessation intervention might be effective for smoking cessation in patients with cerebral infarction, especially when the intervention was implemented thoroughly.

The purpose of this study was to identify the reality of the demand for parent education by mothers of adolescents based on their knowledge of raising a child, related to parenting efficacy and parenting stress. Mothers of 207 middle school adolescents completed questionnaires. Instruments included scales on demand for parent education (Lee, 1995 and Byun, 1999), parenting efficacy (Gibaud-Wallston & Wandersman, 1978), and parenting stress (Kim, 2004 Abidin, 1990). Results showed mothers high in knowledge of parenting had higher parenting efficacy and less parenting stress mothers high in maternalanxiety expressed higher demand for parenting understanding and improvement and for their children's academic adjustment; and mothers with higher maternal parenting stress expressed higher demand for parenting education.

Purpose: This study was conducted to investigate the relationship between self-esteem and coping skills among middle school students. Method: The participants were 674 students in three middle schools in GyeongGi-Do. The data were collected from June 10 to 20, 2005. The instruments used were the Rosenberg Self-esteem Scale and the Ways of Coping Checklist. The data were analyzed using the SPSS-Win 12.0 program. Result: Self-esteem showed a significant positive correlation with positive coping skills (r= .162. p= .000). As for the positive coping skills, there was a significant difference by grade (F= 4.69, p= .010), relationship with parent (F=4.036, p= .02), and relationship with siblings (F=3.902, p= .02). As for the negative coping skills, there was a significant difference by grade (F=3.05, p= .04), condition of living with parents (F=3.559, p= .02), economic status (F=3.736, p= .02), relationship with sibling (F=3.408, p= .03), and troubling matters (F=5.422, p= .005). Conclusion: Positive coping skills may be effective for adjustment because they positively related to self-esteem. Self-esteem and coping skills should be considered when an adolescent's mental health enhancement program is designed.

This study examined how school-age children's peer acceptance and friendship experience were related to their psychosocial adjusment. Peer acceptance was examined in terms of sociometric status and social preference, and the friendship experience was examined in terms of the reciprocity of best friendship. The subjects were 275 children in the 4th or 5th grades. It was found that sociometric status and the reciprocity of best friendship were significant predictors of the level of loneliness that children experienced. Interaction between children's social preference score and the reciprocity of best friendship was also a significant predictor of the children's experience of loneliness. That is, the degree to which children are accepted by their peer group predicts the level of loneliness that children experience, but the strength of the prediction depends on whether the children have reciprocal best friends. Is for children's self-esteem in relation with sociometric status and the reciprocity of best friendship, only sociometric status was significant predictor of children's self-esteem. However, interaction between social preference and the reciprocity of best friendship was a significant predictor of children's self-esteem. This finding suggests that the degree to which children are accepted by their peer group predicts the level of children's self-esteem, and the strength of the prediction depends on whether the children have reciprocal best friends.

The purpose of this study was to analyze the differences in the outcome for CABG according to whether hospitals provided heart related surgeries. The 2011 National Inpatient Sample (NIS) and inpatient quality indicator principles from the Healthcare Research and Quality (AHRQ) were used for analysis. Hospitals were divided into three groups according to the surgeries they provided. The length of stay and in-hospital deaths were adjusted for the differences in risks. ANOVA was performed to examine the differences for the risk-adjusted in-hospital mortality rate and risk-adjusted length of stay among the three groups. The analysis results showed that hospitals providing CABG, PTCA, and PHS had lower risk-adjusted in-hospital mortality rates or similar risk-adjusted lengths of stay compared to those of hospitals providing only CABG. However, the three groups did not have statistically significant differences in outcome indicators. Another study will be needed with a larger sample.

It is crucial to prevent low yields in the semiconductor industry. Since many factors affect variation in yield and they are deeply related, preventing low yield is difficult. There have been substantial researches in the field of yield prediction. Many researchers had used the statistical methods. Many studies have shown that artificial neural network (ANN) achieved better performance than traditional statistical methods. However, despite ANN's superior performance some problems such as over-fitting and poor explanatory power arise. In order to overcome these limitations, a relatively new machine learning technique, support vector machine (SVM), is introduced to classify the yield. SVM is simple enough to be analyzed mathematically, and it leads to high performances in practical applications. This study presents a new efficient classification methodology, Stepwise-SVM (SSVM), for detecting high and low yields. SSVM is step-by-step adjustment of parameters to be precisely the classification for actual high and low yield lot. The objective of this paper is to examine the feasibility of SVM and SSVM in the yield classification. The experimental results show that SVM and SSVM provides a promising alternative to yield classification for the field data.

Objectives : Functional Cerebrospinal Therapy (FCST) is a new physiologic therapeutics developed in Korea as a meridian yinyang balance approach. The theory of yinyang balance has been at the core of health enhancement approach of meridian and acupuncture medicine ever since its start. Methods : Introductory overview of FCST is presented in relation with meridian yinynag balance theory. Results : As the temporomandibular joint (TMJ) and related tissues have direct interconnection with brainstem proprioceptive or motor systems and the face is where all the meridians converge, FCST applies a fine adjustment of the posture of TMJ as a treatment tool for neurologic conditions or meridian imbalances. Conclusions : Highly sophisticated diagnostic and therapeutic techniques to adjust various subset aspects of yinyang balance are developed within FCST, which is supposed to be one of major contributions to natural healing.

Background: Potentially avoidable hospitalizations (PAH) contribute to an increased post-discharge mortality. Methods: To investigate the between-hospital variation and the relationship between all predictors and mortality after discharge among older adults with PAH, we studied 15,186 older patients with PAH in 2,200 hospitals included in the National Health Insurance Service-Senior claims database from 2002 to 2013. Multivariable multilevel logistic regression analyses were performed to analyze the variance at between-hospital for mortality after accounting for differences in patient characteristics. Results: The between-hospital variation in mortality that could be attributed to hospital practice variations were 37.6% at 1-week to 13.9% at 12-month post-discharge, after adjustment for individual patient characteristics and hospital-level factors. Hospital-level factors significantly explained mortality at 3 weeks after discharge. Clinics, compared with general hospitals, demonstrated a 2.75 times higher likelihood of deaths at 3-week post-discharge (p<0.001). Compared with private hospitals, public hospitals exhibited 1.61 times higher odds of 3-week mortality (p=0.01). Conclusion: This study demonstrates considerable between-hospital variations in PAH-related mortality that could be attributed to hospital practices. Monitoring of hospitals to identify practice variations would be warranted to improve the survival of older patients with PAH.
