Concrete filled steel tubular (CFST) composite girder is a new type of structures for bridge constructions. The existing design codes cannot be used to predict the thermal stress in the CFST truss girder structures under solar radiation. This study is to develop the temperature gradient curves for predicting thermal stress of the structure based on field and laboratory monitoring data. An in-field testing had been carried out on Ganhaizi Bridge for over two months. Thermal couples were installed at the cross section of the CFST truss girder and the continuous data was collected every 30 minutes. A typical temperature gradient mode was then extracted by comparing temperature distributions at different times. To further verify the temperature gradient mode and investigate the evolution of temperature fields, an outdoor experiment was conducted on a 1:8 scale bridge model, which was installed with both thermal couples and strain gauges. The main factors including solar radiation and ambient temperature on the different positions were studied. Laboratory results were consistent with that from the in-field data and temperature gradient curves were obtained from the in-field and laboratory data. The relationship between the strain difference at top and bottom surfaces of the concrete deck and its corresponding temperature change was also obtained and a method based on curve fitting was proposed to predict the thermal strain under elevated temperature. The thermal stress model for CFST composite girder was derived. By the proposed model, the thermal stress was obtained from the temperature gradient curves. The results using the proposed model were agreed well with that by finite element modelling.

The purpose of this study was to explore the relationship between personality differences and marital conflict. In particular, this study examined what impact, if any, exists between groups married for fewer than five years(Group 1) and those married for five or more years(Group 2). The sample consisted of 368 married couples. Each couple was asked to complete two questionnaires: one for measuring marital conflict and another for assessing husbands' and wives' personalities using the Myers-Briggs Type Indicator(MBTI). The results of this study were as follows: First, between Group 1 and Group 2, marital conflict showed no differences. Second, no marital conflict, caused by the four types of personality, was found in Group 2. However, for Group 1, the marital conflict perceived by wives was influenced by J-P and S-N types of wives, and the marital conflict perceived by husbands was affected by J-P type of husbands and S-N type of wives. Third, for Group 1, the marital conflict perceived by wives was influenced by the difference between S-N types. The marital conflict perceived by husbands was affected by differences between S-N types and between J-P types. No marital conflict, caused by the difference of the four types of personality, was found in Group 2. The results showed that the four types of personality and the differences in personality types between the couples affected marital conflict, depending on the duration of marriage. Therefore, it is important for the newly married couple to comprehend their spouse's personality and to adjust their lifestyles stemming from their personality differences.

Purpose: The study aimed to translate the Couple Satisfaction Index (CSI 32) into Korean, to evaluate the reliability and validity of CSI 32 and short-form (CSI 16, 4) in the Korean context, and to determine a cut-off score for Korean couples. Methods: Korean Versions of the Couple Satisfaction Index (K-CSI) 32 was translated, back-translated, and reviewed by five bilingual experts. Confirmatory factor analysis (CFA) was conducted with data from a sample of 218 couples (N = 436) to test construct validity. Validity and reliability were evaluated. The receiver's operating characteristics curve analysis was used to obtain the cut-off score. Results: The construct validities of K-CSI 32, 16, and 4 were verified using one-factor structures. The results of CFA showed a slightly better fit for K-CSI 16 and 4 than for K-CSI 32. Convergent validity was supported by significant positive correlations of K-CSI with Kansas Marital Satisfaction Scale, Dyadic Adjustment Scale, and Family Relationship Assessment Scale. Moreover, the significant differences in K-CSI between normal and depressive group demonstrated known-group validity. Cut-off scores of 105.5 on K-CSI 32, 50.25 on K-CSI 16, and 13.25 on K-CSI 4 were validated to identify distressed couple relationships. Conclusion: For clinical practice, the reliable and valid K-CSI 32 has the potential to measure changes in couple satisfaction after couple therapy or interventions. Applying K-CSI 32 may facilitate research on couple and family relationships in nursing and contribute to the discussion on the role of couple satisfaction in mental health.

Objective: As the associations of sperm DNA fragmentation with morphology have not been examined in detail, this study aimed to investigate the relationship between abnormalities of morphological details and DNA integrity in human sperm. Methods: In this cross-sectional study, men from infertile couples were enrolled at Hue Center for Reproductive Endocrinology and Infertility, Vietnam. Conventional semen parameters, including morphological details, were analyzed following the World Health Organization 2010 criteria. Sperm DNA fragmentation was evaluated using a sperm chromatin dispersion assay. The relationships and correlations between semen parameters, sperm morphology, and the type of halosperm and the DNA fragmentation index (DFI) were analyzed. Results: Among 130 men in infertile couples, statistically significant differences were not found in the sperm halo type between the normal and abnormal sperm morphology groups. The percentage of round-head spermatozoa was higher in the DFI >15% group (16.98%±12.50%) than in the DFI ≤15% group (13.13% ±8.82%), higher values for amorphous heads were found in the DFI >15% group, and lower values for tapered heads were observed in the DFI ≤15% group; however, these differences were not statistically significant. Small-halo sperm and the DFI were positively correlated with round-head sperm (r=0.243, p=0.005 and r=0.197, p=0.025, respectively). Conclusion: The rate of general sperm morphological abnormalities in semen analysis was not related to sperm DNA integrity. However, round sperm heads were closely associated with sperm DNA fragmentation.

The purpose of this study is to identify individuals' perceptions of extramarital relationships between themselves and their spouses and to reveal relevant factors. The results of analyzing the data obtained by conducting a survey of married people (402 persons) are as follows: First, the perception of spouse's extramarital relationship turned out to be much more negative than the person's perception of his(her) own extramarital relationship, which led to the discovery of a double standard. Second, men are far more receptive to extramarital relationships than women. Third, factors affecting the perception of extramarital relationships are gender(-.161), age(.144), presence of employment(.107), physical attraction(.087), autonomy(.120), emotional alienation(.105), openness(.124), pervasiveness of extra-marital relationship(.303), and satisfaction with sexual life(-.131). Factors affecting the perception of spouses' extramarital relationships are found to be emotional maturity(-.127), prevalence of extramarital relationships around them(.113) and satisfaction with sex life(1.131). Based on the main findings, various types of practical intervention that can be used to deal with extramarital relations are discussed.

This study is about the nationwide research concerning the degree and trends of marital conflict and instability. The research samples are 1,217 married. As the result of the research, the most conflict able issues in Korean couples are on the husband-wife relations, such as habitual differences, sharing in houseworks, conflicts in the role expectation, and the communication problems. In this study, We devide the marital relationships into 4 types (A, B, C, and D) in the view of the satisfaction & instability of marriage. First, the marriage with unsatisfaction and instability (A) was portioned 8.3%, and the satisfactory & stable type (D) was portioned 68.4%. It seems the marital relationships in Korea are relatively stable. However, the portion of type B-unsatisfactory, but stable couples-is 17.1% and the type C-satisfactory, but unstable marriage 6.2%. The result implies that the indication of marital instability should consider not only the divorce rate, but also the quality of marital relationships. In other words, the intervention for the conflict couples yet not divorce is needed. The differences of conflict areas among the relational types is not so much, but the degrees on conflicts are very serious. Especially, in the areas of marital conflict, love issues and personal value system affect the division of relational types of marriage most. It means the interaction factors are the most important variables about maintaining the marital relations with stable and satisfaction.

Purpose: This study aimed to examine the relationship between pre and post operative sexual condition, differences in sexual attitude through post operational periods, and the relationship between sexual attitude and satisfaction. Method: Data was collected with questionares from 119 women registered in the gynecology department of a general hospital in Seoul who had undergone a hysterectomy. Result: There was a significant difference between the condition of pre and post operation coital frequency, sexual satisfaction, and spouse's attitude toward the extraction of the partner's uterus. There was a significant difference between their views of the operation. Twelve months after the operation sexual attitude of sexual aspects changed, but not in physical and psychological aspects. There was a significant difference between sexual attitude and satisfaction on sexual, psychological aspects, but not physical aspects. Conclusion: The findings suggest that a preliminary sexual condition be identified before surgery, scheduling the operation after helping a spouse gain a positive attitude about the hysterectomy, and couples in their 50's and older get counselling. Increased sexual satisfaction will develop with a belief in positive changes of sexual aspects, but a rapid change should not be expected.

Purpose: This study the mediating effects of marital intimacy the relationship between depression and marital satisfaction of infertile women. Methods: 165 infertile women visiting a hospital in Gyeonggi-do and Busan, Korea from January 2016 to April 2016. The data was analyzed the SPSS WIN 22.0 program. Results: Depression, marital satisfaction, and marital intimacy averaged $1.51{\pm}.32$ (range of scale 0~3), $3.50{\pm}.56$ (range of scale 1~5), and $3.74{\pm}.65$ (range of scale 1~5), respectively. Depression had a negative correlation with marital satisfaction (r=-.361, p<.001) and marital intimacy(r=-.183, p<.001). Marital intimacy also had a positive correlation with marital satisfaction (r=.637, p<.001). Marital intimacy partial mediating effects between depression and marital satisfaction (${\beta}=.591$, p<.001). Conclusion: the intimacy of couple can alleviate the causal consequences that lead to a decrease in the marital satisfaction due to depression. Therefore, healthcare providers for infertile women should screen depressed women and help support infertile women from negative values for marriage depression. In addition, it is necessary to include interventions for maintaining and enhancing the intimacy of couples during infertility treatment.
