The purpose of this study was to help the athletic students of the boys' and girls' high schools improve their competence by examining closely into the difference of the stress patterns according to their sex, grade, event, career. To achieve the goal of this study. We analyzed the statistics of 340 athletic students of 13 athletic sports events. On the basis of collected data. We used one-way ANOVA and T-test to verify the difference in the sports stress according to sex, grade, event, career of the athletes at the high schools. First, the result of T-test concerning stress of the high school athletes on the basis of sex, showed that there were meaningful differences statistically in the burden of failures, the worry about going on to university (p<.001), the concern about a wound, and the others(p<.05). Second, the result of one-way ANOA conceerning stress of the high school athletes on the basis of school grade, showed that there were meaningful differences in the conflict among people(p<.001), the burden of punishment, the burden of economy, and the others(p<.05). Third, the result of T-test concerning stress of the high school athletes on the basis of sports events, showed that there were meaningful differences statistically in the burden of studying(p<.05). Fourth, the result of one-way ANOVA concerning stress of the high school athletes on the basis of sports career, showed that there were meaningful differences statistically in the concern about a wound(p<.05).

The Suwon Campus of Kyunghee University was decided to rebuild a university gate to make new image of the university for a new millenium. The purpose of this study is to design a university gate not only for a gate but also for a commemorative environmental model which presents a spirit and idea of the Kyunghee University. The entire design of the gate has a renaissance style, the design of it's center has a triumphal arch form which cars can go through, and the design of it's side has a corridor form which pedestrians can walk. The gate is designed to present the spirit for human and world peace which Kyunghee University intends.

During 2012 to 2014, a survey for the presence of viral diseases in yam plants was carried out in a field of the Institute for Bioresources Research in Gyeongsangbuk-do, Korea. A total of 88 leaf samples were collected and tested by reverse transcription polymerase chain reaction using specific primer sets. Eighty-one samples were positive for Broad bean wilt virus 2 (BBWV2), Chinese yam necrotic mosaic virus (ChYNMV), Cucumber mosaic virus (CMV), Japanese yam mosaic virus (JYMV), and Yam mild mosaic virus (YMMV), whereas Yam mosaic virus (YMV) was not detected. Additionally, seven samples were negative for all viruses. Several samples exhibited mixed (double and triple) infections. Three viruses (CMV, JYMV, and YMMV) were detected for the first time in yam plants in Korea. A BLAST search showed that three viruses shared nucleotide identities with CMV-Ca (98%), JYMV-O2 (91%), and YMMV-TG_NH_1 (86%). Thus, our findings confirmed that yam plants cultivated in Korea were infected with multiple viruses with three of these viruses reported for the first time in Korea.

Objective: The aim of this study is to investigate the various causes of male infertility using multiple approaches. Methods: Nine-hundred-twenty infertile male patients were analyzed at their first visit with one physician between January 1 and December 31, 2009. All patients were subjected to physical examination and semen analysis and azoospermic patients underwent hormonal testing, chromosomal tests, and testicular biopsy. Semen analysis was based on the definition of the World Health Organization. Results: Among the 920 patients, 555 patients (60.3%) had semen results within the normal range, 269 patients (29.2%) within the abnormal range, and 96 (10.5%) were diagnosed with azoospermia. Varicoceles were diagnosed in 84 of the 555 normal-range patients (15.1%) and in 113 of the 269 abnormal-range patients (42.0%). Of the 96 patients with azoospermia, 24 patients (25%) were diagnosed with obstructive azoospermia, 68 patients (71%) with non-obstructive azoospermia, and 4 patients (4%) with retrograde ejaculation. Conclusion: Various causes of male infertility have been reported and diverse treatment methods can be adopted for each cause. In this regard, research must be conducted on a larger number of patients to accurately assess the various causes of infertility in Korean patients and to investigate various infertility treatment methods.

<P>Herein, an electrically switchable cholesteric liquid crystal (LC) shutter from visible to infrared light was prepared using a dual frequency LC (DFLC). The fabricated device is semitransparent to visible and IR light in the planar state and opaque in the focal conic state. Both visible and IR lights are transmitted in the homeotropic state. Interestingly, switching among these states is possible by just varying the voltage and frequency. In addition, it is possible to switch between the planar (homeotropic) and homeotropic (planar) states without going to the focal conic state. The proposed device can even regulate the ambient temperature by controlling the sunlight without losing transparency. Thus, the device is expected to have potential applications as smart windows of automobiles and buildings to control the interior temperature and save energy.</P>
