  • This article examines some factors that should be taken into consideration as the number of arbitrators to constitute arbitral tribunal, how to select them and the characteristics of arbitrators by their expert field, and the various problems that may arise in selection of arbitrators. When dispute parties select one arbitrator or a chairman of arbitral tribunal, they should consider the characteristic of case. When legal problem is more important, they should select a lawyer, whereas when trade practice is more important, they should select a businessman. Especially, when they decide to select a businessman as one arbitrator or a chairman of arbitral tribunal, they allow him not to write the reason of award if possible because he is lack of know-how to write it. Also, dispute parties should acquire the information of the main career and character of arbitrator, his experience of arbitration and so on before they select him.

  • There are several studies that relate oxidative damage as possible mechanism for many cancers. Many studies have also shown that anti-oxidants like selenium and vitamin E decrease the risk for prostate cancer. The main objective of the Selenium and Vitamin E Cancer Prevention Trial (SELECT) study was to look for the benefits of selenium and vitamin E supplementation on prostate cancer. The study had a large sample size, stringent experimental conditions, very long duration, standardized laboratories for biochemical analyses and other factors that contribute to high external validity. The SELECT study failed to show any significant risk reduction for prostate cancers ascribable to selenium and vitamin E supplementations. Because of these conflicting results, many researchers argue about the methods used, supplementations administered (selenium and vitamin E) and indicators used for assessing levels of supplementations. We reviewed many epidemiological studies, clinical trials, and pre-clinical studies. With corroborative evidences we justify that SELECT study has a sound methodology and rationale. In lieu of the contrary results of the select study, researchers should focus on the probable mechanisms for these contrary findings and continue their search for newer and effective agents for prevention of prostate cancer.

  • This study examines the role of visual merchandising (VMD) in creating effective interior displays for fashion "select shops"(shops that carry a wide selection of brands) amid the recent changes in consumption trends, with consumer needs becoming increasingly individualized and diversified. Fashion select shop interior displays can be categorized as self-service, showcase, counter, and environmental display spaces. Regarding the VMD elements that contribute to effective interior displays, we reached the following conclusions. First, in self-service displays, in order to heighten sales efficacy, display elements should be presented in such a way as to enable customers to select products with ease by themselves. Second, the mere presence of showcase displays was found to be insufficient; if, however, select shops use showcase displays to arrange products according to the flow of customer traffic, enabling the creation of a gentrified atmosphere for products, this may contribute to a differentiated image of brands, heightening perceived product value. Third, in counter displays, having a harmonious arrangement of display and presentation elements promotes sales by inspiring customer confidence. Fourth, regarding environmental displays, it is important for stores to have attractive interior designs and decorations in order to reproduce settings in which products are actually used, as this can inspire interest in products and promote customers' purchasing intention.

  • It is well known that discard of seminal plasma from the semen and separation of motile sperm should be preceded before insemination for IUI or IVF. Till now, more than ten kinds of semen treatment methods have been developed. Of those, swim-up and Percoll methods have been used widely in ART laboratories as a routine semen treatment methods because of its advantages. However, there are reports that Percoll can make a genetic trouble because of its chemical structure and therefore the necessity has been arisen to substitute Percoll for other equivalent materials. This study was performed to evaluate the effects of three different sperm preparation methods (swim-up, Percoll and Sil-Select) on sperm motility, sperm recovery rate and fertilization rate. Also, the feasibility of using Sil-Select instead of Percoll in ART was evaluated. Each semen samples were divided into three fractions and motile sperm were recovered by swim-up, Percoll and Sil-Select gradient centrifugation methods. Normal and sub-normal criteria of fifteen semen samples and seventeen IVF cycles were included in these study. As results, no significant difference was found in sperm recovery rate in normal semen treated by a Swim-up, Percoll and Sil-Select method ($13.2{\times}10^6,\;17.5{\times}10^6\;and\;17.7{\times}10^6$ respectively). The initial sperm motility was 61.9% and this increased to 87.1%, 92.6% and 89.5% through Swim-up, Percoll and Sil-Select treatment, respectively. Higher motility was observed in Percoll and Sil-Select treated groups (81.5%, 79.2%, respectively) than swim-up group (66.8%) after incubation for 24hrs. In sub-normal group, sperm recovery rates were higher in Sil-Select group $(2.9{\times}10^6)$ than Percoll gradients group $(1.8{\times}10^6)$. In IVF cycles, the outcomes of fertilization using sperm treated by swim-up and Sil-Select group were similar (82.2%, 79.7% respectively). In conclusion, our results indicate that Sil-Select can be used as a substitute material for sperm preparation instead of Percoll.

  • Objectives: The purpose of the study was to investigate the influence of employment preparation behavior on motive to select dental hygiene as their major, and their work value among dental hygiene students. Methods: A self-reported questionnaire was completed by 444 dental hygiene students in South Korea from November 1 to 30, 2016. To analyze the data, the study used independent t-test, one way ANOVA, Pearson's correlation analysis, and regression analysis among others. Results: There were employment preparation behavior (2.9), major selection motive (3.1), and their work value (3.8) in subject. The higher student's grade is, the better prepared he or she for employment (p<0.001). Inner work value (p<0.01) and outer work value (p<0.05) were higher among females than males. Employment preparation behavior had significant positive effect on personal, social motive to select dental hygiene as their major, and their inner work value. Conclusions: Positive motivation to employment preparation behavior leads to major motive to select major, and their work value. It is necessary to consider study of diversified manners that can be fulfilled for employment preparation behavior.

  • In this study, a comparative test operation was conducted through the alternate haul method to examine the selectivity of the four mesh sizes (60 mm, 90 mm, 110 mm, and 130 mm) of the trawl codend. The selectivity was analyzed using the SELECT model considering the fishing efficiency (split parameter) of each fishing gear in the comparative test fishing operation in the trawl and the maximum likelihood method for parameter estimation. A selectivity master curve was estimated for several mesh sizes using the extended-SELECT model. As a result of analyzing the selectivity for silver croaker based on the results of three times hauls for each experimental gear, it was found that the size of the fish caught increased as the size of the mesh size increased. When the selectivity for each mesh size analyzed by the SELECT model considering the split ratio was evaluated based on the size of the AIC value, the estimated split model was superior to the equal split model. Based on the master curve, the 50% selection length value was 2.893, which was estimated to be 136 mm based on the mesh size of 60 mm. In some selectivity models, there was a large deviance between observed and theoretical values due to the non-uniformity of the distribution of fished length classes. As a result, it is considered that appropriate sea trials and selectivity evaluation methods with high reliability should be applied to present trawl fishery resource management methods.

  • Objective: To evaluate silane-coated silica particles (Sil-select) as an alternative to polyvinylpyrrolidone-coated particles (Percoll) for gradient separation of spermatozoa, for use in assisted reproduction. Methods: 20 normal semen based on WHO criteria were included in this study. Recovery of motile and morphologically normal spermatozoa after using two-layer Percoll and Sil-select gradient respectively was recorded. Motility, HOST (hypoosmotic swelling test) and the detection of malondialdehyde for LPO (lipid peroxidation) after 24 h of incubation at $37^{\circ}C$ in a 5% $CO_2$ incubator were compared. Results: Percoll (78.5%) and Sil-select (79.1%) showed a significant increase in the motility compared to ejaculate (60.9%) but no difference between Percoll and Sil-select. Normal sperm morphology significantly increased after Percoll (57.6%) and Sil-select (53.7%) compared to ejaculate (35.8%) but no difference between Percoll and Sil-select. No differences in the recovery of motile spermatozoa and motility, HOST and the production of malondialdehyde after 24 h incubation were found when comparing the use of Percoll and Sil-select. Conclusion: Sil-select seems to be an attractive alternative to Percoll for sperm separation in assisted reproduction.
