There are not many studies on job satisfaction among older workers living alone. This study examined the determinants of job satisfaction for older workers living alone, and the job satisfaction was analyzed by the demographic-social factors, the health-psychological factors, and labor factors regarding to sex and ages. Korean Labor and Income Panel Study(KLIPS, 18th) used in this study, and the subjects were 308 older worker living alone and over 55 years old. The determinants of job satisfaction for male respondents were happiness, organizational commitment, and duration of work. Howver, the determinants of job satisfaction for female respondents were age, happiness, organizational commitment, and levels of skill. Income, organizational commitment, employment stability, and duration of work were the determinants for 55-64 years old. Education, organizational commitment, and levels of skill were the determinants for 65-74 years old. Education and happiness were the determinants for 75 years old and over. Age, income, happiness, organizational commitment, employment stability, duration of work, and levels of skill were the determinants of job satisfaction for all respondents. Finally, this study proposed the policy and practical implications for improving of job satisfaction among older workers living alone.

The purpose of this study is to explore the mediating effect of violence justification, including actor-effect and partner-effect, in the process where the offense motive affects dating violence. The subjects of this study were 135 unmarried male and female couples aged 19 and over who were dating for more than 3 months, and each couple was subjected to a self-report scale on motives, justification of violence, and dating violence. Based on these paraphrasing, as a result of analyzing the path model using the Actor-Partner Interdependence Model, Men and women's motivations showed a direct effect on their dating violence, while women's motivations showed a significant partner effect on men's violence. The male's motivation also had a significant impact on his dating violence and partner's abuse of dating violence as a mediator for justification of his violence. On the other hand, the mediating effect of justifying violence in women was not significant. These results show that there is a gender difference between the motives for violence and the paths for justifying violence in the sex violence of men and women. Finally, the implications and limitations of this study, and suggestions for follow-up studies were discussed.

This study is a descriptive survey research to investigate the effect of communication skills of college students on interpersonal satisfaction and subjective happiness. Data were collected using structured questionnaires from 222 students attending two universities located in C and S cities between June 1 and June 10, 2016, and were analyzed using t-test, One-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and hierarchical multiple regression, etc. The results of the study are as follows. The communication skills of the subjects were found to be 2.13 out of 1~5 points, and it was found that there was a significant difference according to grade, perceived home economy level, and leisure activities. Second, communication skills showed a positive correlation with interpersonal satisfaction and subjective happiness. Third, in relation to interpersonal satisfaction, the explanatory power of sex, grade, academic achievement, perceived family economic level and leisure activity was 26.7%, and communication skills further explained 18.4% of interpersonal satisfaction. Fourth, in relation to subjective happiness, the explanatory power of subjective gender, academic achievement, perceived family economic level and leisure activity was 33.0%, and communication skills further explained only 0.3% of subjective happiness. The results of this study suggest that communication-related education can be used as a major intervention strategy in the development of programs to improve interpersonal satisfaction and happiness of college students.

Purpose: Anastomotic leakage (AL) is associated with high morbidity and mortality, high reoperation rates, and increased hospital length of stay. Here we investigated the risk factors for AL after anterior resection for rectal cancer with a double stapling technique. Patients and Methods: Data for 460 patients who underwent primary anterior resection with a double stapling technique for rectal carcinoma at a single institution from 2003 to 2007 were prospectively collected. All patients experienced a total mesorectal excision (TME) operation. Clinical AL was defined as the presence of leakage signs and confirmed by diagnostic work-up according to ICD-9 codes 997.4, 567.22 (abdominopelvic abscess), and 569.81 (fistula of the intestine). Univariate and logistic regression analyses of 20 variables were undertaken to determine risk factors for AL. Survival was analysed using the Cox regression method. Results: AL was noted in 35 (7.6%) of 460 patients with rectal cancer. :Median age of the patients was 65 (50-74) and 161 (35%) were male. The diagnosis of AL was made between the 6th and 12th postoperative day (POD; mean 8th POD). After univariate and multivariate analysis, age (p=0.004), gender (p=0.007), tumor site (p<0.001), preoperative body mass index (EMI) (p<0.001), the reduction of TSGF on 5th POD less than 10U/ml (p=0.044) and the pH value of pelvic dranage less than or equal to 6.978 on 3rd POD (p<0.001) were selected as 6 independent risk factors for AL. It was shown that significant differences in survival of the patients were AL-related (p<0.001), high ASA score related (p=0.036), high-level EMI related (p=0.007) and advanced TNM stage related

This study attempts to review the increasing trend in international marriage of Koreans since 1990 and explore the pattern of socio-demographic characteristics of the married couples. This paper develops a conceptual scheme for changing pattern of nuptiality including an increase in international marriage. As the key forces behind the recent increase in international marriage of Koreans, the effects of rapid decline in fertility, rise in sex ratio at birth, urbanward migration of young women, expansion of gender-equity norms, and globalization are stressed. Micro-data from the marriage registration for the period $1990{\sim}2004$ and the divorce registration for the period $2000{\sim}2004$ are utilized. This study focuses on analyzing age at marriage, previous marital experience, education, occupation, and residence of the married couples. Attention is also focused on demographic characteristics of the divorced couples. Results of analyses reveal that there exists a great deal of diversity in international marriage of Koreans. A notable aspect is the profound differences between Korean men and women in the characteristics of their foreign spouses and themselves as well. Another prominent factor emphasized in the analysis is the nationality of foreign spouse. It is indicated that the stereotype of international marriage facilitated by marriage squeeze can be mainly applied to marriages between Korean men and foreign wives from China, southeast Asian countries and the CIS of the old Soviet Union. On the other hand, direct effects of value transformation and globalization are emphasized in the explanation of marriages between Korean men and foreign wives from more developed countries as well as marriages between Korean women and foreign husbands.

Objectives: Although sleep paralysis (SP) has been known as one of the symptoms of narcolepsy, recently it has become recognized as occurring frequently in the general population. However, the prevalence of SP and its associated factors in patients with major psychiatric disorders remain unknown. This study investigated the prevalence of SP and a variety of associated experiences in those patients. Methods: The subjects were 160 psychiatric patients and 143 age- and sex-matched controls. The Korean version SP questionnaire as well as the Sleep-Wake Schedule, Epworth Sleepiness Scale and Insomnia Severity Index were administered to all the subjects. The patients were referred from Dong-A University Hospital and consisted of 74 diagnosed as schizophrenia (47.7%), 26 as bipolar disorder (16.8%) and 55 as major depression (35.5%). Results: Nearly 42% of the patient group and 39% of the control group had experienced at least one episode of SP in their lifetime, with no significant difference between the groups. However, the patient group had experienced SP more frequently than the control group. Among all subjects, no gender difference in SP incidence was found. The peak age of onset was in the range of 16-25 years for both groups. Over eight tenths of both groups reported hallucinations and over seven tenths of both groups experienced fear accompanying SP. Conclusion: This study shows that there is no difference in the lifetime prevalence of SP between psychiatric patients and the general population, whereas frequency of SP experience is higher in psychiatric patients. Terrifying hallucinations and fearful feelings frequently accompany SP in both groups.

Background: NPAS2 is a product of the circadian clock gene. It acts as a putative tumor suppressor by playing an important role in DNA damage responses, cell cycle control and apoptosis. Chronic lymphocytic leukemia (CLL) appears to be an apoptosis related disorder and alteration in the NPAS2 gene might therefore be directly involved in the etiology of CLL. Here, the Ala394Thr polymorphism (rs2305160:G>A) in the NPAS2 gene was genotyped and melatonin concentrations were measured in a total of seventy-four individuals, including thirty-seven CLL cases and an equal number of age- and sex-matched healthy controls in order to examine the effect of NPAS2 polymorphism and melatonin concentrations on CLL risk in a Pakistani population. Materials and Methods: Genotyping of rs2305160:G>A polymorphism at NPAS2 locus was carried out by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Melatonin concentrations were determined by enzyme linked immunosorbent assay (ELISA). Statistical analysis was performed using Statistical Package for Social Sciences software. Results: Our results demonstrated no association of the variant Thr genotypes (Ala/Thr and Thr/Thr) with risk of CLL. Similarly, no association of rs2305160 with CLL was observed in either females or males after stratification of study population on a gender basis. Moreover, when the subjects with CLL were further stratified into shift-workers and non-shift-workers, no association of rs2305160 with CLL was seen in either case. However, significantly low serum melatonin levels were observed in CLL patients as compared to healthy subjects (p<0.05). Also, lower melatonin levels were seen in shift-workers as compared to non-shift-workers (p<0.05). There was no significant difference (p>0.05) in the melatonin levels across NPAS2 genotypes in all subjects, subjects with CLL who were either shift workers or non-shift-workers. General Linear Model (GLM) univariate analysis revealed no significant association (p>0.05) of the rs2305160 polymorphism of the NPAS2 gene with melatonin levels in any of the groups. Conclusions: While low melatonin levels and shift-work can be considered as one of the risk factors for CLL, the NPAS2 rs2305160 polymorphism does not appear to have any association with risk of CLL in our Pakistani population.
