Selecting, at my option, 44 male children and 33 female children at Kyung-nam Sports Academy kindergarten sports club in Chang-won city. I conducted a survey into correlation between 2 items of physique and 5 items of physical strength. And the results are as follow : 1. On height of physique male children' height show 3.33cm increase as average 101.70cm in March to average 111.03mn in November, whereas female children' height show 4.43cm increase as average 103.70cm in March to average 108.13cm. It means that female's growth is faster than male's one. 2. On weight of physique male children' weight show 1.73kg increase as average 18.68kg in March to average 20.41 in November. Whereas female children' weight show 1.73kg increase as average 17.91kg in March to average 19.64kg in November. 3. On physical strength, male children made an excellent 25m run, sit-ups, standing broad jump, V-form sitting, but female children made an excellent foot balance. 4. On correlation between height and physical strength for male children 25m run(.294) in March and 25m run(.377), sit-ups(.309) in November have a little correlation. For female children, in March 25m run(-.626), foot balance(-.531), standing long jump(.684), V form-sit(-.480) have a distinctive correlation whereas in November 25m run(-.412) and V form-sit (-.313) have a little correlation. 5. On correlation between weight and physical strength for male children 25m run(-.301), sit-ups(.312), V form-sit(.331) in March have a little correlation and foot balance(.306) in November have a little correlation. For female children, 25m run(-.491), foot balance(.434), standing long jump(.472), V form-sit(-.452) in March have a distinctive correlation, also foot balance(-.409), sit-ups(.47), V4 form-sit (-.621) in November have a little correlation.

PURPOSE. A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS. Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, χ2 test was used and significant level (α) was set up as 0.05. RESULTS. Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION. Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.
청각장애학교에서 실시한 통합교육이청각장애학생의 건청학생에 대한 인식에 미치는 효과
이정우,이은숙 한국청각언어장애교육학회 2012 한국청각·언어장애교육연구 Vol.3 No.1
The purpose of this study was to examine an effect of inclusive education fulfilled in deaf school on the perception of students with hearing impairment toward students with hearing. The perception of students with hearing impairment toward students with hearing was negative because of the ignorance kidding of students with hearing before this program. But through this program, students with hearing impairment got the confidence that students with hearing impairment can help students with hearing while teaching sign language to students with hearing. And their interpersonal skills with students with hearing were improved through the inclusive educational program focusing on activities such as ping pong and recreation. 이 연구는 청각장애학교에서 실시한 통합교육이 청각장애학생의 건청학생에 대한 인식에 미치는 효과에 대해 알아보고자 하였다. 이 프로그램에 참여하기 전 청각장애학생들은 건청학생들과 의사소통의 어려움, 무시, 놀림 등으로 건청학생에게 좋지 않은 감정을 갖고 있거나 부정적 인식을 하고 있었다. 그러나 청각장애학교에서 실시한 통합교육을 받으면서 건청학생을 만날 때 자신감을 가지게 되었고, 건청학생들과의 긍정적 상호작용을 통해 건청학생에 대한 인식이 긍정적으로 변화하는 것을 볼 수 있었다. 이 프로그램에 참여하여 수화를 건청학생들에게 가르쳐 보면서 청각장애학생도 건청학생을 도울 수 있다는 자신감을 가지게 되었고, 탁구, 레크리에이션과 같은 활동 중심의 통합교육 프로그램을 통해 건청학생과의 대인관계 능력도 향상시키게 되었다.

To enhance the solubility and stability of lansoprazole (LAN), new proton pump inhibitor, we were prepared various molar ratio of inclusion complex with 2-hydroxypropyl-(3-cyclodextrin (HPCD) and organic alkali agent, meglumine (MEG). Inclusion complex formation of LAN with HPCD was investigated by Differential Scanning Calorimetry and X-ray diffractometry. The aqueous solubilities of inclusion complexes, and the stabilities of 1:4 and 1:5 inclusion complexes in aqueous solutions containing different concentrations of MEG were examined. The stability of 1:5 LAN-HPCD inclusion complex containing MEG, which was equaled to amount of LAN, was performed in 0.9% NaCl and 5% dextrose solution. The formation of inclusion complex of LAN with HPCD was AL type and the molar ratio of complex was 1:1. The stability constant was 41.557 M^(-1). As molar ratio of LAN to HPCD was increased, solubility of inclusion complex was increased. 1:5 LAN-HPCD inclusion complex was more stable than 1:4 LAN-HPCD inclusion complex. And as contained MEG amount in LAN solution was increased, stability of 1:4 and 1:5 LAN-HPCD inclusion complexes was improved. Also stability of 1:5 LAN-HPCD-MEG inclusion complex in 0.9% NaCl solution and 5% dextrose solution was similar to it in water at room temperature, but it was unstable at 40℃.
한,중,일 협력의 과제와 전망 : 북한 군사력의 평가와 한국의 안보정책 방향
이정우 제주평화연구원 2013 Jpi정책포럼 Vol.130 No.-
한국전쟁 이후 한국사회에서 ``신화``로 이어지고 ``북한의 상대적 군사력 우위``라는 명제는 현재 시점에서도 유의미한 안보적인식을 제공하는가에 대해 비판적 시각이 필요하다. 이른바 남북한의 안보딜레마는 상대의 군사력에 대한 과대인식과 그 의도를 불신하면서 반세기가 넘도록 강화되고 있다. 압도적이라고 할 수는 없지만 현재 한국은 북한에 대해 ``잠재군사력``이나 ``전쟁수행능력``에서 우위를 점하고 있으며, 특히 한미연합방위력의 차원에서 볼 때 그 능력은 훨씬 크다.따라서 한반도 안보의 평화적 미래구상을 위해서는 북한의 군사력에 대한 객관적이고 냉철한 평가를 통해 이에 기반한 적정 수준의 군비증강 계획, 효율적 군사개편과 첨단화 등이 필요하다. 남한이 재래식 군사력에서 ``압도적`` 우위를 점하는 것은 북한을 핵?미사일과 같은 비대칭 무기 개발에 집중하게 하여 오히려 한국의 안보를 위협하는 악순환을 만들 수 있기 때문이다.따라서 남북한 평화 구축을 위한 군비통제의 중요성은 이제 한국의 주도로 제안되고 실천되어야 할 긴급한 과제가 되고 있다.또한 2015년으로 예정된 전시작전통제권 전환 문제 역시 안보문제의 주도적인 측면에서 적극적으로 획득되어야 할 사안이다.

도축장에서 회수한 한우 난소로부터 난자를 회수하기 위한 방법으로 흡입법 후 세절법과 흡입법으로 난자를 회수하여, 난자의 회수율과 채란된 난자를 체외수정 후 발달율과 수정란 이식 후 수태율에 영향을 조사한 결과는 다음과 같다. 1. 난자 회수율은 각 난소당 회수된 난자수는 흡입 후 세절법이 8.2개, 흡입법이 6.5개로서 흡입 후 세절법을 병용하는 것이 난자 회수율에서 유의적으로 많았다. 2. 채란방법에 따른 체외수정란의 분할율은 흡입 후 세절법이 , 흡 This study was undertaken to access the effect of collection methods on the collection efficiency, blastocyst rate and pregnancy rate after IVP embryo transfer. The ovaries of Hanwoo were obtained from an abattoir and kept on 25 to and transported to laboratory within 4 hrs. The oocytes were collected by aspiration of follicles with or without slicing of ovaries after aspiration. The oocytes were matured in vitro (IVM) for 20 to 24 hrs in TCM-199 supplemented with fetal bovine serum at under in air. Following routine IVM/IVF procedure, the oocytes and presumed zygotes were cultured for three day in CRlaa medium with BSA. The cumulus cells at 2 to 8-cell stage of embryos removed then the embryos and were cultured in CRlaa medium containing fetal bovine serum in at . The fresh blastocysts cultured for 7 to 9 days were transferred into recipients. The numbers of oocytes recovered form two different methods, the aspiration and slicing after aspiration, were compared to know what. The number of oocytes per ovary was 8.2 and 6.5 in aspiration combining slicing, and aspiration groups, respectively (p<0.05). The cleavage rate in aspiration method are significantly (p<0.05) high than those in slicing post aspiration , and aspiration . The pregnancy .ate in aspiration method was high than that in slicing method after aspiration . The pregnancy rates of aspiration method and slicing method after aspiration in nullipara was high than that in pluripara . The results obtained that the increased number of oocytes per ovary in slicing method after aspiration could be better than that in aspiration method. Pregnancy rate in aspiration method was slightly higher in than that in slicing method after aspiration.
