The purpose of this study was to investigate the relationship of perception of error, deliberate practice, and perceived performance of University Taekwondo Athletes. To this end, 321 Taekwondo athletes (male 207, female 114) participated in this study. Collected data were analyzed by descriptive statistics, correlation, and multiple regression using SPSS 22.0 version. The results revealed as follow. First, learning from error, error risk taking, and thinking about error had a positive effect on deliberate practice. Second, learning from error and thinking about error had a positive effect on performance satisfaction while error risk taking and thinking about error had a positive effect on will to win. Third, deliberate practice had a positive effect on performance satisfaction and will to win. In conclusion, athletes’ perception of error is key component to enhance deliberate practice and perceived performance. Furthermore, deliberate practice was also identified as a variable that improves perceived performance.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

밀양 204호는 작물과학원 영남농업연구소 생명공학연구팀이 직파적응 제초제저항성 벼 품종을 육성할 목적으로 '98년 bar 유전자를 동진벼에 아그로박테리움법으로 형질 전환하여 제초제저항성 벼를 양성하였다. '98/'99년 동계에 단간 내도복 양질인 주남벼를 인공교배하여 약배양 등 육종프로그램에 적용하여 우량계통을 선발하고 밀양 204호로 계통명을 부여하였다. GM 벼와 Non-GM 벼의 농업적 특성을 UPOV 및 국립종자관리소의 품종등록 기준에 따른 농업적특성 중 차이가 있었던 것은 엽색도, 지엽의 형태, 간장, 수당립수 등 이었다. This study was conducted to investigated the major characteristics of genetically modified rice of 'Milyang 204' originated from Dongjinbyeo compared to a non-transgenic rice varieties Dongjinbyeo and Jun-ambyeo. Basta resistant transgenic rice lines carrying bar gene produced by the Yeongnam Agricultural Research Institute were evaluated for their agronomic characters. The transgenic Japonica rice of 'Milyang 204' showed inferior phenotypic traits compared to a non-transgenic rice variety Dongjinbyeo and Junambyeo. On the basis of UPOV (Union Internationale Pour la Protaection des Obtentions Vegetables) and NSMO(National Seed Management Office) the transgenic 'Milyang 204' showed difference in some traits out of some agronomic traits, such as leaf color, angle of flag leaf, number of spikelets, culm length, white core and white belly compared to the non-transgenic varieties rice.

Dependence of the intermixing of InGaAs/InGaAsP quantum well on capping layers
Won Jun Choi,Deok Ha Woo,Hee Taek Yi,Jung Il Lee 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.3
The dependence of impurity-free vacancy disordering (IFVD) of InGaAs/InGaAsP quantum well (QW) structure with various semiconductor capping layers over the QW structure on the characteristics of the dielectric capping layer was studied by using SiO2 and SiNx lm as capping layers. Thermal treatment of samples has shown that the amount of blue-shift depends not only on the dielectric capping material but also on the semiconductor capping material over the QW structure. It has been shown that a SiNx dielectric capping layer induces larger blue-shift of bandgap than a SiO2 capping layer for any semiconductor capping layer. For the semiconductor capping layer, it has been shown that an InP capping layer induced the largest blue-shift of bandgap and an InGaAs capping layer induced the smallest blue-shift of bandgap. The combination of dielectric-semiconductor capping condition has been proposed in order to obtain the largest dierential bandgap shift spatially.
