  • Objective: The purpose of this study is to determine the optimal time of transportation of floor-feed and scatter-feed broilers. Methods: Eighty healthy Arbor Acres (AA) broilers (21-day-old, 624.4 g, male, standard error = 6.65) were selected and randomly divided into two experimental groups (floor-feed and scatter-feed), then fed for three weeks. The experiment comprised a 2×4 factorial design with 2 feed patterns (floor-feed and scatter-feed) and 4 transport periods (2, 3, 4, and 5 h), and 4 replicates of 5 broilers (54-day-old, 2243 g, standard error = 46.65) was used to compare weight loss, meat quality and behavior index of different groups. Results: It appeared that drip loss, meat color and resting behavior of experimental broilers changed as length of transportation (p<0.05), however, weight loss and pH were not significantly transformed (p>0.05). Compared with floor-feed group, broilers in scatter-feed group had lower pH at 24 hours (3 h) and different behavioral indicators (p<0.05). Especially indicators after 3 h transportation, there were obvious differences between the two feeding modes in the behavior reaction of stress events before slaughter with different transport duration (p<0.05). The fluctuation of data on resting behavior with scatter-feed was significantly higher than that of floor-feed broilers. There was no interaction between transport time and different feeding methods for index tested of our experiment (p>0.05). Conclusion: Comprehensive analysis showed that the maximum transport duration of floor-feed and scatter-feed broilers should not exceed 3 h, and scatter-feed broilers were more likely prone to fear.

  • Recently, increasing attention has been paid to the welfare of farm animals, which have been evaluated using behavioral and physiological measures. However, so far, the measures have almost always been used to estimate poor welfare. In this review, firstly we focus on how oxytocin (OT) relates to positive social behavior, pleasure, and stress tolerance, and second on which management factors stimulate OT release. OT induces maternal and affiliative behaviors and has an anti-stress effect. Further, OT is produced during enjoyable events, and has positive feedback on its own release as well. Therefore, to some extent, the relationship of OT to positive normal behavior was mutually beneficial-heightened OT concentration owing to comfortable rearing conditions induces positive social behavior, which in turn may increase OT concentration. Hence, studies on animal welfare should pay more attention to increasing comfort and the stress tolerance, rather than only focusing on when stress occurs in farm animals.

  • The Korean Hanhyup broiler has commercialized native meat-type chicken. This study aimed to determine the effects of two types of litter material-sawdust and rice husk, and gender on the Korean Hanhyup broiler. Chicks (n=416) were randomly assigned in a $2{\times}2$ factorial design by type of litter material and gender. The behavior of chicken's was monitored continuously for 12 hours during the $1^{st}$ through $8^{th}$ week of age. The time spent on standing, sitting, and walking and the frequency of drinking, feeding, preening, dust bathing, flapping, and aggressive pecking, and pecking of chicken's behavior were recorded. The behavior of chickens during the starter (1 to 4 weeks) and finisher period (5 to 8 weeks) was compared to observe the changes upon maturity. Our results indicate that litter material type and gender have no effect on the behavior of chickens. However, aggressive pecking and pecking caused increment in the rice husk as compared to sawdust (P<0.05). Sawdust as litter material for bedding was found to be better than rice husk with respect to Korean Hanhyup broiler behavior.

  • This paper presents some of the results from an experimental research project on the behavior of extended end-plate connections subjected to moment conducted at the Structural Laboratory of Jordan University of Science and Technology. Since the connection behavior affects the structural frame response, it must be included in the global analysis and design. In this study, the behavior of six full-scale stiffened and unstiffened cantilever connections of HEA- and IPE-sections has been investigated. Eight high strength bolts were used to connect the extended end-plate to the column flange in each case. Strain gauges were installed inside each of the top six bolts in order to obtain experimentally the actual tension force induced within each bolt. Then the connection behavior is characterized by the tension force in the bolt, extended end-plate behavior, moment-rotation relation, and beam and column strains. Some or all of these characteristics are used by many Standards; therefore, it is essential to predict the global behavior of column-beam connections by their geometrical and mechanical properties. The experimental test results are compared with two theoretical (equal distribution and linear distribution) approaches in order to assess the capabilities and accuracy of the theoretical models. A simple model of the joint is established and the essential parameters to predict its strength and deformational behavior are determined. The equal distribution method reasonably determined the tension forces in the upper two bolts while the linear distribution method underestimated them. The deformation behavior of the tested connections was characterized by separation of the column-flange from the extended end-plate almost down to the level of the upper two bolts of the lower group and below this level the two parts remained in full contact. The neutral axis of the deformed joint is reasonably assumed to pass very close to the line joining the upper two bolts of the lower group. Smooth monotonic moment-rotation relations for the all tested frames were observed.

  • Purpose: This study was conducted to explore sexual attitude, sexual behavior and the related factors in chinese-Korean university students. Method: A self-administered questionnaire with cross-sectional design was used. Participants were 271 Chinese undergraduate students in one university in Jilin, China. Correlation coefficiency and t-test were used to find the relationships and to compare sexual attitude and sexual behavior and related factors. Result: Although sexual attitude of participants was moderate, they were more likely to be engaged in sexual behavior. The strong relationship between sexual attitude and sexual behavior suggested that those who have a permissive sexual attitude were more likely to have engaged in sexual behavior. The participants who responded that their parents have a less permissive attitude about sexual activity were less likely to be engaged in sexual behavior. There were significant relationships between sexual behavior and other variables, such as dating, experience of sexual activity, smoking and grades. Conclusion: Students who have a higher score of sexual attitude and had an experience of sexual activity were more likely to be at higher risk of being sexually.

  • The purpose of this research is to determine the influence of affectionate child-rearing behavior on children's self esteem. The sample group was composed of 200 forth and sixth grade elementary school students. The statistics used for this data were frequency, percentile, averages, standard deviation, Cronbach's alpha, t-test, Pearson's correlation, and stepwise multiple regression analysis. The major findings of the research were as follows: First, the scores of affectionate child-rearing behavior(3.60), global self-worth(3.58), social acceptance(3.46) and behavior conduct(3.28) were higher than the mean scores. On the contrary the scores of cognitive ability(2.95), physical ability(2.94) and physical appearance(2.85) were lower than the mean scores. Second, there were significant differences in cognitive ability based on gender(p<.01) and global self-worth based on grade(p<.05). Third, the influence of affectionate child-rearing behavior on children's self esteem was found to be significant due to the sub-areas of self-esteem. Affectionate child-rearing behavior affects all sub-areas of self-esteem. Affectionate child-rearing behavior affects cognitive ability(p<.001), physical ability(p<.01), physical appearance(p<.01), social acceptance(p<.001), behavior conduct(p<.01) and global self-worth(p<.001). In addition, gender(p<.01) affects cognitive ability and grade(p<.05) affects global self-worth.

  • The research aims to evaluate college students' financial behavior and provide empirical insight into factors that may influence their financial behavior by investigating whether financial socialization, financial experience, and financial literacy are meaningful for students' financial behavior. The surveys data was conducted with 595 college students from all over Indonesia then analyzed using Structural Equation Model (SEM). The results demonstrate that financial socialization positively influences financial literacy and financial behavior. On the other hand, financial experience has a negative influence on financial literacy, yet a positive one on financial behavior. Furthermore, the result also shows financial socialization are the key determinant of financial literacy and financial literacy is vital and plays an essential role for financial behavior and it may derive from financial socialization and financial literacy. It indicates that the influence of social agents can benefit students in improving their financial literacy and behavior. However, experience also can influence their financial behaviors. The lack of experience of college students leads to inadequate financial knowledge and raises their risk of financial decisions. Students with sufficient financial knowledge and exhibiting good financial behavior can make wise decisions in financial planning and management, thus may prevent financial issues in the future.

  • The purpose of this study is to assess the associations among person-environment fit, organizational citizenship behavior, organizational commitment and turnover intent in the foodservice industry. The study was administered to 306 Korean employees. The results indicated a positive relationship between person-environment fit, employees' organizational citizenship behavior and organizational commitment. However, person-environment fit did not have a significant, direct impact on their turnover intent. Thus, this study found an indirect influence via organizational citizenship behavior and organizational commitment. In addition, organizational citizenship behavior and organizational commitment were negatively associated with employees' intention to leave the organization. Limitations and future research directions are also discussed.
