Purpose - The purpose of this study is to specify the relationship between demographic cohesion and firm performance by examining the roles of HR practices, such as job rotation and flexible work arrangement. Design/methodology/approach - This study samples 1,093 firms in Korea and collects their data between 2007 and 2017 from Workplace Panel Survey, a database from Korea Labor Institute. The demographic cohesion is measured using the Herphindal-Hershman index and the firm performance is measured with net incomes. This study employs a fixed-effects model for the estimation of firm performance with respect to demographic cohesion, job rotation, and flexible work arrangement. Findings - There is a positive relationship between demographic cohesion and net incomes. And the relationship is positively moderated by job rotation. However, flexible work arrangement shows a mixed moderation. Research implications or Originality - Differentiated from the studies on demographic diversity, this study shows that demographic cohesion has a mixed impact on firm performance. While demographic cohesion can improve firm performance through trust building, in-group favoritism, and collective identity it entails internal conflicts. However the link between demographic cohesion and firm performance is moderated by job rotation and flexible work arrangement. While there is a positive moderation of job rotation, there is a negative moderation of flexible work arrangement.

This study was conducted to examine the effect of family environment on smoking behavior, smoking knowledge and smoking attitude in primary school students. For the purpose of the study, a questionnaire-based examination was made with 1,476 sixth-grade students in Taegu from November 1st to 30th, 1998. The results of the study are summarized as follows. Out of 22 points for smoking knowledge, the male student group got 12.9 points, and the female student group 13.0 points. For both groups, students with better school achievement showed a significantly higher score (p<0.01). For the female student group, those who had nonsmoking fathers showed a significantly higher score(p<0.05). A perfect score for smoking attitude was 20 points. The male student group received 14.9 points and the female student group 16.3. For both groups, the score appeared to be significantly higher in the students who had better school achievement and no smoking experience. For the female group, the score was higher if they were living with widowed mothers or had nonsmoking parents. The percentage of smoking experience was 22.0% for the male group and 4.7% for the female group. The present smoking percentage of both groups accounted for 0.3% and 0.1%, respectively. The percentage of the male group's smoking experience was significantly higher if school achievement was poor, if the mother has religious, and if her occupation belonged to significantly different category. For the female group, it was significantly higher if a mother's educational background was less than the primary school level, or if a mother smokes. Family adaptability and cohesion were not significant variables for both groups. The score for smoking knowledge according to family cohesion was highest if male and female members were in an enmeshed state. For the female group, the higher the family adaptability, the significantly higher the score for smoking knowledge. The score for smoking attitude according to family cohesion showed a significant difference for both groups. The family adaptability was not a significant variable for both groups. The results of multiple regression analysis, with the scores for smoking knowledge and smoking attitude were used as a dependent variable, revealed that, for both groups, the better the school achievement. For the female group, the higher the family cohesion, the significantly higher the score(p<0.01). For the male group, the score for smoking attitude was significant1y higher if school achievement was better, if students were living with a widowed mother or father, if they had drinking mothers, if family adaptability was low, if family cohesion was high, or if the score for smoking knowledge was high. For the female group, the score for smoking attitude was higher if school achievement was better. Also, if famale student had nonsmoking fathers, if the family adaptability was lower, on the higher the score for smoking knowledge, a smoking attitude scored higher. The results of a multiple logistic analysis, with smoking experience as a dependent variable, revealed that, for the male student group, the worse the school achievement, the higher the score for smoking knowledge, the lower the score for smoking attitude, or the lower the family adaptability, the higher the percentage of smoking experience. For the female student group, the higher the score for smoking knowledge or the lower the score for smoking attitude, the higher the percentage of smoking experience. In conclusion, family environment, including smoking of parents and family functions, had a great effect on smoking knowledge, smoking attitude and smoking experience of students, and it is required to adjust subjects and methods for smoking and nonsmoking education as smoking attitude and smoking behavior greatly differ according to sex.

The purpose of the descriptive correlation study was to examine relations among the hope, the burden and the family function in mothers caring for children with cancer. 145 mothers completed the three questionaires of the study divided into tree sections: a) The Hope Scale, b) The Burden Scale, c) FACES-Ⅲ. The collected data was analysed with t-test, ANOVA, Scheffe test and Pearson correlation coefficients. The results were as follows: 1) The average age of mothers of children with cancer was 35.6 years old and the ages between 30 to 39 were the most abundant. 57.3％ of the mothers had an education level of below high school education and 66.0％ had religion. The average age of the children was 8.6 years old. Ages between 1 to 7 were the most and 60.8％ were diagnosed as leukemia. 2) Regarding the section of degree of burden, mothers of children with cancer marked 2.6 out of 5, and the degree of hope 3.2 out of 4. The result for family function came out to be 3.5 out of 5, an average of family cohesion of 3.9 and family adaptation of 3.1. 3) There were significantly less burden to the mothers who were living together with a spouse compared to the mothers who were not. Also mothers who replied that they preserved good health came out to be exposed to less burden compared to the mothers who did not. In analysing hope according to the general characteristics of mothers of children with cancer, mothers who were employed marked high in the degree of hope compared to unemployed mothers. Furthermore, the degree of family cohesion marked higher with mothers who had higher education of college graduate, mothers with religion and mothers with a monthly family income of over ￦3,000,000, compared to the group of mothers with lower education of high school graduate, non-religious or with a monthly family income of less than ￦1,000,000. 4) Excluding the fact that the group sorted with children diagnosed as leukemia marked a perceivably high score regarding family cohesion, compared to groups with other cancers, the degree of burden, hope and family cohesion did not show any noticeable difference according to characteristics of children with different cancers. 5) In the correlation of the hope, the burden and the family function regarding the mothers of children with cancer, the burden did not have any manifest relationship with hope or family function. However, the degree of hope and family function cohesion had a direct proportional relationship, as family cohesion marked higher when the degree of hope were high.

The mechanical properties of expansive soil are very unstable, highly sensitive to water, and thus easy to cause major engineering accidents. In this paper, the expansive soil foundation pit project of the East Huada Square in the eastern suburb of Chengdu was studied, the moisture content of the expansive soil was considered as an important factor that affecting the mechanics properties of expansive soil and the stability of the non-equal-length double-row piles in the foundation pit support. Three groups of direct shear tests were carried out and the quantitative relationships between the moisture content and shear strength τ, cohesion c, internal friction angle φ were obtained. The effect of cohesion and internal friction angle on the maximum displacement and the maximum bending moment of piles were analyzed by the finite element software MIDAS/GTS (Geotechnical and Tunnel Analysis System). Results show that the higher the moisture content, the smaller the matrix suction, and the smaller the shear strength; the cohesion and the internal friction angle are exponentially related to the moisture content, and both are negatively correlated. The maximum displacement and the maximum bending moment of the non-equal length double-row piles decrease with the increase of the cohesion and the internal friction angle. When the cohesion is greater than 33 kPa or the internal friction angle is greater than 25.5°, the maximum displacement and maximum bending moment of the piles are relatively small, however, once crossing the points (the corresponding moisture content value is 24.4%), the maximum displacement and the maximum bending moment will increase significantly. Therefore, in order to ensure the stability and safety of the foundation pit support structure of the East Huada Square, the moisture content of the expansive soil should not exceed 24.4%.

The purpose of this study is to understand the sliding characteristics of the infilling-joint surface using the new devised shear test apparatus with changeable slope for the original infilling materials and the infilling materials experienced cyclic freezing-thawing processes. Three types of the mother rock classified as the igneous rock, the metamorphic rock and the sedimentary rock and the infilling materials were collected for laboratory test. The cohesion according to the slope change of the rock joint shows large variation within ${\pm}$5 degrees but the internal friction angle shows appears the linear decreasing tendency. It is confirmed that the affecting factor of slope change of rock joint at the behavior of rock mass is larger than that of the infilling thickness. Test results show that the cohesion and the internal friction angle in 100 times of cyclic freezing-thawing processes are decreased about 50 percent compared with original one. A further study using various infillings materials would lead to a better understanding of the failure mechanism of rock mass by slope change of rock joint.
