In this study, we investigated the effects of mixing on the aggressive behavior of commercially housed pigs. The behavioral patterns of 36 groups of pigs (a total of 360 animals) were observed over 3 consecutive days directly after weaning ($25{\pm}1.2$ days of age), and 25 and 50 days later with the aid of video technology. Fight latency and total duration and frequency of fighting were significantly different among the age groups. The aggressive behaviors decreased in 75-day old pigs if compared to 25- and 50-day old animals. Moreover, dominance index (DI) was higher in 25-day old and lower in 75-day old pigs. A comparison of dominant (DI>0) and submissive (DI<0) pigs showed significant differences (p<0.05) for major aggressive behaviors in all age groups. Dominant pigs were involved in more aggressive interactions, had longer fights, and initiated more fights than submissive pigs. Post-mixing aggressive behavior was altered by previous experience of mixing. Aggressive behavior and DI are suitable methods for analyzing the effects of mixing on commercially housed growing pigs.

Purpose: In this study, behavioral styles of Dominance, Influence, Steadiness, and Conscientiousness (DISC) were examined and differences in job satisfaction and clinical competence among newly hired nurses were explored. Methods: For this explanatory correlational research, 176 newly hired clinical nurses were recruited from three university hospitals and one general hospital located in Seoul and Gyeonggi province. Data were collected in August, 2013 though self-report questionnaires. Results: The distribution of behavioral styles was 11.4%, 42%, 29% and 17.6% for Dominance, Influence, Steadiness, and Conscientiousness respectively. DISC behavioral styles were associated with sub-areas of job satisfaction such as professional position and doctor-nurse relationship. DISC behavioral styles were significantly associated with the total score for clinical competence and sub-areas of data collection, basic nursing skills, critical thinking, education and leadership, and attitudes toward professional development and practical skills. Multiple linear regression analysis showed that DISC behavioral styles predicted clinical competence (Adj. $R^2$=.14, F=9.42, p<.001). Conclusion: A focus on cultivating influential and steady behavioral styles among newly hired nurses can be helpful in improving job satisfaction and clinical competence. There is a need to improve interpersonal relationships through a deeper understanding of each person's behavioral style based on the analysis of DISC behavioral styles.

Purpose: Human factor is one of the major causes of medication errors. The purpose of this study was to identify nurses' perception and experience of medication errors, examine the relationship of Dominance, Influence, Steadiness, Conscientiousness (DISC) behavior patterns and medication errors by nurses. Methods: A descriptive survey design with a convenience sampling was used. Data collection was done using self-report questionnaires answered by 308 nurses from one university hospital and two general hospitals. Results: The most frequent DISC behavioral style of nurses was influence style (41.9%), followed by steadiness style (23.7%), conscientiousness style (20.4%), and dominance style (14.0%). Differences in the perception and experience level of medication errors by nurses' behavioral pattern were not statistically significant. However, nurses with conscientiousness style had the lowest scores for in experience of medication errors and the highest scores for perception of medication errors. Conclusion: The results of this study show that identification of the behavior pattern of nurses and application of this education program can prevent medication errors by nurses in hospitals.

This study identified the effect of changes in the riverbed on the benthic macroinvertebrate communities. The benthic macroinvertebrates collected from the surveyed sites belonged to 119 species, 65 families, 20 orders, and 7 classes in 4 phyla. The number of Ephemeroptera, Plecoptera, and Trichoptera (E.P.T) species was 42, 10, and 8, respectively, in the tributary, confluence, and Nakdong River sites. Lotic species (Hydropsychidae) showed a high density at the tributary sites, whereas lentic species (Chironomidae) showed a high density at the confluence and Nakdong River sites. Community analysis showed that the Dominance Index (DI) was 0.54 in tributary sites, and dominance indices increased closer to the Nakdong River sites. The diversity index (H') was inversely proportional to DI. The ratio of Burrowers species (BU) at the surveyed sites increased closer to the Nakdong River sites. Analysis of common species showed 37 species (34.6%) between the tributary and confluence sites and 66 species (51.5%) between the confluence and Nakdong River sites.

The purpose of this paper is to present a qualitative case study on teaching English as an international language in Korean context. The researcher investigated the implementation process of the new elementary English program from the government to local schools to find out to what extent the symbolic value of English as an international language affect the implementation process of the elementary English program. The research result showed that the elementary teachers shared the different views of the status of English from those of government and the parents, and their differing perception of the role of English constantly affected their implementation efforts. The research findings also revealed that the public's concern of English dominance in Korean educational system resulted in the government's 'comprised curriculum' by lowering the learning goals of the English program. The findings also indicated that the introduction of the elementary English program accelerated English dominance in both teacher and student culture. The question of how to resolve the conflict between acquiring English proficiency and its negative influence on Korean culture remains a complex issue in implementing the new elementary English program.

This experiment was performed to obtain the basic information on heterosis and heterobeltiosis of quantitative characters in the eggplant by crossing of varieties. The heterosis and heterobeltiosis were estimated in Fl generation. The results were as follows, based on the graphical analysis, the characters, plant height, stem diameter, fruit weight, leaf length, leaf width, and fruit number per plant(yield) were assumed to inherit dominance, and fruit length and fruit diameter were found to inherit incomplete dominance. The degree of positive heterosis of plant height, stem diameter, fruit weight, fruit length, fruit diameter, leaf length, leaf width, and fruit diameter, leaf width, leaf length, fruit weight, and stem diameter showed negative heterobeltiosis.

Tests were conducted on two partially pre-stressed concrete solid beams subjected to combined loading of bending, shear and torsion. The beams were designed using the Direct Design Method which is based on the Lower Bound Theorem of the Theory of Plasticity. Both beams were of $300{\times}300mm$ cross-section and 3.8 m length. The two main variables studied were the ratio of the maximum shear stress due to the twisting moment, to the shear stress arising from the shear force, which was varied between 0.69 and 3.04, and the ratio of the maximum twisting moment to the maximum bending moment which was varied between 0.26 and 1.19. The required reinforcement from the Direct Design Method was compared with requirements from the ACI and the BSI codes. It was found that, in the case of bending dominance, the required longitudinal reinforcements from all methods were close to each other while the BSI required much larger transverse reinforcement. In the case of torsion dominance, the BSI method required much larger longitudinal and transverse reinforcement than the both the ACI and the DDM methods. The difference in the transverse reinforcement is more pronounce. Experimental investigation showed good agreement between design and experimental failure loads of the beams designed using the Direct Design Method. Both beams failed within an acceptable range of the design loads and underwent ductile behaviour up to failure. The results indicate that the Direct Design Method can be successfully used to design partially prestressed concrete solid beams which cater for the combined effect of bending, shear and torsion loads.
