The purpose of the study was to identify the relationship of the logistics activities with the overall performance among the Korean industries, in order to suggest ways of enhancing the level of effectiveness in logistics management. On the basis of current logistics literature and research data, an analysis had been attempted to provide the study with a theoretical framework, followed by an empirical research that analyzed, among the randomly selected companies, the relations between logistics activities and management policy; logistics activities and logistics environment; logistics environment and the usage of computer software; management policy and the usage of computer software; management policy and performance; logistics environment and performance. Analyses of the data suggested that the companies that lay heavy emphasis on logistics effectiveness showed higher performance; management policies of the companies are influenced by their logistics characteristics; the more strongly is a company oriented logistically, the higher effectiveness in logistics activities it maintains; there is a significant relationship between the logistics environment a company is operated in and the company's reliance on logistically oriented information technologies; there is a close relationship between a company's logistics activities and its business outcome.

This study was conducted in order to develop an aptitude test for child care teachers (ATCCT) and to analyze it in terms of both validity and reliability. The main participants in this study consisted of 710 pre-service child care teachers. The results of factor analysis identified 7 factors and 56 items which were selected from 121 items in the original scale. The seven factors were as follows; interpersonal relationship management abilities, receptiveness and responsiveness to children, creativity and personal development, the ability to form close relationships with children, the ability to supervise child safety, the sense of duty, and positive emotions. The four factors were related to social relationship. Criterion-related validity was established by using correlations between the ATCCT and the TSES (Teacher Self-efficacy Scale). The internal consistency was found to be relatively high (Cronbach's ${\alpha}$ = .94) and test-retest reliability was also established (r = .53). In addition, there were differences among pre-service child care teacher groups according to both relative levels of education and courses taught.

We have examined the relationship between the speeds of coronal mass ejections (CMEs) and the GOES X-ray peak fluxes of associated flares. Noting that previous studies were possibly affected by projection effects and random association effects, we have considered two sets of carefully selected CME-flare events: four homologous events and four well-observed limb events. In the respective samples, good correlations are found between the CME speeds and the GOES X-ray peak fluxes of the associated flares. A similarly good correlation is found for all eight events of both samples when the CME speeds of the homologous events are corrected for projection effect. Our results suggest that a close relationship possibly exists between CME kinematics and flaring processes.

Objectives : The purpose of the study is to investigate the relationship between employment stress and oral symptoms in health college students. Methods : A self-reported questionnaire was filled out by 275 health college students in Seoul from October 7 to November 29, 2013. The data were analyzed using SPSS WIN 14.0 program. Results : Female students tended to have higher employment stress oral symptoms than male. The higher the employment stress was, the more oral symptoms were. There was a close relationship between personal trait, environmental stress and oral symptoms. Regression analysis showed that tongue, teeth, gum, temporomandibular joint(TMJ) were influenced by the employment stress. Conclusions : It is important to reduce the environmental stress in the students. The students themselves must try to overcome the agonal condition by diverting stress into positive way of living.

The purpose of this paper is to review relationship between social integration and social capital in the residential redevelopment districts based on the system thinking perspective using causal loop analysis. The results are as follows. First, social exclusion phenomena brings about relative deprivation for rental housing occupants feeling left out and close by area residents. This acts as a motive triggering antisocial activities for the rental housing occupants. Second, rental housing and housing for installment should be mix-developed to improve social exclusion phenomenon issues. Third, increase of creating work program in the relationship between residential redevelopment districts and social capital boosts employments, individual earnings, and local area investments. The conclusion provides some research implications and future research direction.

The Genetic diversity and relationship of native Siri (Bos indicus) cattle populations of Bhutan were evaluated using 20 microsatellite markers. A total of 120 Siri cattle were sampled and were grouped into four populations according to their geographical locations which were named Siri West, Siri South, Siri Central and Siri East cattle. For each, 30 individuals were sampled. In addition, 30 samples each of Indian Jaba (B. indicus), Tibetan Goleng (B. taurus), Nepal Hill cattle (B. indicus), Holstein Friesian (B.taurus) and Mithun (B. frontalis) were typed. The mean number of alleles per loci (MNA) and observed heterozygosity (Ho) were high in the Siri populations ($MNA=7.2{\pm}0.3$ to $8.9{\pm}0.5$ and $Ho=0.67{\pm}0.04$ to $0.73{\pm}0.03$). The smallest coefficient of genetic differentiation and genetic distance ($F_{ST}=0.015$ and $D_A=0.073$) were obtained between Siri West and Siri Central populations. Siri East population is genetically distinct from the other Siri populations being close to the Indian Jaba ($F_{ST}=0.024$ and $D_A=0.084$). A high bootstrap value of 96% supported the close relationship of Siri South, Siri Central and Siri West, while the relationship between Siri East and Jaba was also supported by a high bootstrap value (82%). Data from principal component analysis and individual assignment test were in concordance with the inference from genetic distance and differentiation. In conclusion we identified two separate Siri cattle populations in Bhutan at the genetic level. One population included Siri cattle sampled from the West, Central and South of the country and the other Siri cattle was sampled from the East of the country. We suggest that Siri cattle conservation program in Bhutan should focus on the former population as it has received less genetic influence from other cattle breeds.

Skeletal class III had been classified by the position of the maxilla, the mandible, the maxillary alveolus, the mandibular alveolus and vertical development. This morphologic approach is simple and useful for clinical use, but it is insufficient to permit understanding of the pathophysiology of dysmorphoses. The author hypothesizes that there are different patterns of mutual relation of the skeletal components which have contributed pathologic equilibrium of skeletal class III. The purpose of this study are threefold: 1) to classify skeletal class III in subgroups, which can show the architectural characteristics of the deformity, 2) to analyse the craniofacial architecture of each subgroup on etio-pathogenic basis, and 3) to characterize and visualize the pattern as a prototype. Materials used in this study were lateral cephalograms of 106 skeletal class III adults, which were analysed with modified Delaire's architectural and structural analysis. Linear and angular measurements of the individual subject were obtained and cluster analysis was used for the subgrouping. Data were evaluated for verification of the statistical significances. The following results were obtained. 1. By the modified Delaire's architectural and structural analysis and cluster analysis, skeletal class III adults were classified into 7 clusters and presented as prototypes, which could show the pathophysiology of the skeletal architecture 2. There was significant relationship in measurement variables of each cluster, which could reflect characteristics of the skeletal pattern of growth. 3. The flexure of cranial base had a close relationship to the anterior rotational growth of the maxilla and contributes to understand the etio-pathology of skeletal class III. 4. The proportion of craniospinal area in cranial depth, craniocervical angle and vertical position of point Om had a close relationship to rotational growth of the mandible and direction of condylar growth. They contribute to understand the etio-pathology of skeletal class III. In summary, the cranium and the craniocervical area must be considered in diagnosis and treatment planning of dentofacial deformity. And the occlusal plane can be considered as a representative which shows the mutual relationships of the skeletal components.

Attempts have been made to establish relationship between the response to ACTH challenge in female calves, growth and first lactation performance. A total of 19 Holstein calves weighing 100 kg i. v. were given 0.50 IU of ACTH/kg $BW^{.75}$ (EXACTHIN inj., Richter G., Budapest) at 60 days of age. Serial blood samples were taken at times 0, 0.5, 1, 2, 3, 4 and 5 hours and analyzed for cortisol, glucose insulin and FFA levels. From challenge series the area under the curve from time of administration and the following 5 h were calculated. Negative, and mostly loose relationship between response to ACTH challenge for cortisol, insulin, or FFA and ADWG during growth have been established (p>0.05) with positive one for glucose. Bivariate coefficients of correlation varied within the range from -0.35 to 0.15. Estimations reveal negative correlation between the length of first lactation and cortisol or insulin (r=-0.80, p<0.001 and r=-0.45, p<0.10, resp.) Close association between cortisol or insulin and actual first lactation milk yield was found (r=-0.48, p<0.10; r=-0.64, p<0.01, resp.). Close relationship between the response to ACTH challenge and milk protein yield was present only for insulin (r=-0.59, p<0.05).
