Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

In this study, and analytical method for ride sensitivity analysis of a train with non-linear suspension elements are proposed. Non-linear characteristics of springs and dampers for primary and secondary suspensions of a train are parameterized using polynomial interpolation. Vertical dynamic model of a three-body train running on straight rail with the predetermined roughness expressed in terms of spectral density function is set up and its equations of motion for ride analysis are derived. Using the direct differentiation method, sensitivity equations of the vertical dynamic model with respect to design parameters associated with non-linearity of suspensions are obtained. Based on the sensitivity analysis, improvement of ride is achieved by varying appropriate suspension parameters.

Diverse multimedia services will be deployed at hand on 3G-and-beyond multi-service CDMA systems in order to satisfy different quality of service (QoS) according to traffic types. In order to use appropriate resources efficiently the call admission control (CAC) as a major resource control mechanism needs to be used to take care of efficient utilization of limited resources. In this paper, we propose a QoS-aware CAC (QCAC) that is enabled to provide service fairness and service differentiation in accordance with priority order and that applies the different thresholds in received power considering different QoS requirements such as different bit error rates (BER) when adopting total received power as the ceil load estimation. The proposed QCAC calculates the different thresholds of the different traffic types based on different required BER applies it for admission policy, and can get service fairness and differentiation in terms of call dropping probability as a main performance metric. The QCAC is aware of the QoS requirement per traffic type and allows admission discrimination according to traffic types in order to minimize the probability of QoS violation. Also the CAC needs to consider the resource allocation schemes such as complete sharing (CS), complete partitioning (CP), and priority sharing(PS) in order to provide fairness and service differentiation among traffic types. Among them, PS is closely related with the proposed QCAC having differently calculated threshold per each traffic type according to traffic priority orders.

The objective of this study was to investigate the diagnosis and treatment of Retinal vein occlusion such as syndrome differentiation and herbal medicine by reviewing Chinese traditional medicine`s journals. The journal search was carried out using China National Knowledge Infrastructure and Pubmed from January 2000 to December 2014. Searching key words were the various combination of "Retinal vein occlusion", "traditional chinese medicine", "syndrome differentiation". The final selection of 11 studies were selected and summarized by researchers. The effective rate was significantly higher than control but, methodological quality of the trials was generally low questioning their liability. The syndrome differentiation was classified as hyperactivity of liver yang and blood stasis. The most frequently prescribed herbal medication was Hyulbuchookeotang, Boyanghwanotang and Cheomagudeungum. This finding could be widely utilized in future clinical practice and form the basis for the development of clinical practice guidelines in advance.

Complex diseases, such as stroke and cancer, have two or more genetic influences and are affected by environmental factors, which complicate them. Due to the complex characteristics of these diseases, we must search and study comprehensive literature-based article resources. Some disease-related literature databases have been developed through specialized journal issues or major websites. Most of them, however, are scattered throughout a website, and users encounter difficulties in finding accurate and comprehensive information easily and quickly. We developed StrokeMed, an integrated literature database for stroke and the differentiation of stroke syndrome. The system allows users to explore PubMed search results, categorized by MeSH (Medical Subject Headings), and the differentiation of stroke syndrome in Oriental medicine. StrokeMed collects data from important sites, such as PubMed, Scirus, and Scopus, automatically to maintain higher-quality and updated content. Currently, the system indexes more than 20,000 PubMed abstracts that are related to stroke, stroke etiology, and Oriental medicine. The system provides valuable literature information to the scientific and medical fields in stroke.

Objectives: The objective of this study is to develop the diagnostic tool to distinguish between cold syndrome (CS) and heat syndrome (HS). Methods: A total of 1,753 subjects were divided into three groups, those are CS group, intemediate group, and HS group, by the mean and standard deviation of the cold heat syndrome differentiation score using 7 point scale consisting of 9 items. Demographic characteristics, diseases history, health status, Mibyeong, syndrome differentiation were analyzed. Results: CS is characterized by women, elderly, and low body mass index. CS has a history of thyroid disease, cataract, depression, osteoporosis, and HS has a history of prostatomegaly. CS receives less social psychosocial stress than HS, and the quality of life associated with health status is lower than HS. CS group has the tendency to be tired, painful, sleepless, dyspeptic and anxious. Conclusions: CS is a set of symptoms associated with decreased energy metabolism and decreased metabolic function, and is more likely to be unhealthy than HS.

The nature of the implant surface can directly influence cellular response, ultimately affecting the rate and quality of new bone tissue formation. The aim of this in vitro study was to investigate if human osteoblast-like cells, Saos-2, would respond differently when plated on disks of magnesium titanate and machined titanium. Magnesium titanate disks were prepared using Micro Arc Oxidation(MAO) methods. Control samples were machined commercially pure titanium disks. The cell adhesion, proliferation and differentiation were evaluated by measuring cell number, and alkaline phosphatase(ALPase) activity at 1 day and 6 day after plating on the titanium disks. Measurement of cell number and ALPase activity in Saos-2 cells at 1 day did not demonstrate any difference between machined titanium and magnesium titanate. When compared to machined titanium disks, the number of cells was reduced on the magnesium titanate disks at 6 day, while ALPase activity was more pronounced on the magnesium titanate. Enhanced differentiation of cells grown on magnesium titanate samples was indicated by decreased cell proliferation and increased ALPase activity.

Marbling (intramuscular fat) is the most economically important meat quality trait in Hanwoo (Korean cattle). The endothelial differentiation G-protein coupled receptor 1 (EDG1) gene, involved in blood vessel formation, is located within the genomic region of a quantitative trait locus (QTL) for marbling on bovine chromosome 3. Thus, the EDG1 gene can be considered as a positional and functional candidate gene for meat quality in beef cattle. This study aimed to identify single nucleotide polymorphisms (SNPs) in the EDG1 gene and to evaluate their associations with carcass traits in Hanwoo population. We have sequenced a fragment of 5'-UTR of the EDG1 gene and identified one SNP. Genotyping of the g.166A>G SNP marker was carried out using PCR-RFLP analysis in 309 Hanwoo steers in order to evaluate their association with carcass traits. The g.166A>G SNP marker showed a significant effect on the marbling score. Animals with the GG genotype had higher marbling score compared with AA and AG genotypes (p<0.05). This SNP marker also showed a significant additive effects for the marbling score (p<0.05). These results suggest that the EDG1 gene can be used as a molecular marker for DNA marker-assisted selection in order to increase the levels of the marbling score in Hanwoo.
