The commercial relationship between South and North Korea is defined under the concept of economic relation and cooperation. To resolve any dispute that can arise from the trade and investment relations between South and North Korea, 'Agreement on the Procedures to Resolve Commercial Arbitration of South-North Korea' came into force in August 2003. Commercial Arbitration Committee of South-North Korea will be organized as the member lists of the committee were exchanged in July 2006 between South and North Korea. This committee must become a central system to settle the trade and investment disputes between South and North Korea. North Korea's Foreign Economic Arbitration Act was enacted to provide the foreign investors with the safe measures in their investments such as dispute resolution. But this Act can not dispute the trade and investment disputes between South and North Korea. The purpose of this paper is to contribute to the activation of arbitration between South and North Korea by studying Commercial Arbitration Committee of South-North Korea introduced by Agreement on the Procedures to Resolve Commercial Arbitration of South-North Korea and Agreement on the Construction and Operation of Commercial Arbitration Committee of South-North Korea and finding the problems and solutions of Commercial Arbitration Committee of South-North Korea.

Poplar(Populus nigra)를 대상으로 組織培養時 callus 生長과 anthocyanin形成에 影響을 미치는 環境條件으로써 最適培地, 糖의 效果, 植物生長調節劑, 糖의 種類 및 日長의 影響을 검토하고자 遂行한 결과는 다음과 같이 요약된다. 1. SH 培地가 callus 및 anthocyanin형성에 효과적이었고 sucrose濃度는 5.5%가 우수하였다. 2. Auxin류의 효과에 있어서는 2,4-D 2.0 ㎎/ℓ에서 callus 및 anthocyanin형성에 가장 효과적 이었다. 3. Cytokinin류에서 BA가 kinetin에 비하여 callus生育을 顯著하게 抑制하였고 kinetin 0.2㎎/ℓ에서 anthocyanin형성이 가장 우수하였다. 4. 糖의 종류로는 fructose가 sucrose나 glucose에 비하여 callus增殖에 월등히 높은 효과를 보였고 anthocyanin形成量에는 큰 차이를 보이지 않았다. 5. 日長의 效果에서 anthocyanin形成은 日長이 길어질수록 促進되었으며 callus형성은 日長에 따른 차이를 보이지 않았다. The experiments were conducted to optimize culture conditions for callus growth and anthocyanin formation by in vitro culture of Populus nigra through tests of basal media, inorganic salts, plant growth regulators, sucrose concentrations, sugar and photoperiods. SH media supplemented with 55 g/l sucrose gave the best results in callus and anthocyanin formation. For the effects of plant growth regulators, anthocyanin formation was promoted by treatment with 2.0 ㎎/l 2,4-D. On the other hand, 0.2 ㎎/l kinetin showed the highest activity for anthocyanin synthesis while BA severely suppressed callus growth. Fructose compared with glucose remarkably promoted callus growth but anthocyanin formation showed no difference with sugar type. Anthocyanin pigment accumulation hastened by increasing photoperiod in culture room while callus growth was not affected with photoperiod.

김대성,최근원,정인식,이승우 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

본 실험은 치커리 'Radicchio'(Cichorium intybus L.)에서 Agrobacterium을 이용한 형질전환에 영향을 주는 요인들을 적정화하기 위하여 실시되었다. 치커리 'Radicchio'의 자엽절편체를 이용한 kanamycin과 cefotaxime 항생제 감응성 검정 결과 20 mg·L^(-1) 이상의 kanamycin 농도가 형질전환 신초의 선발에 적당하고 200 mg·L^(-1)의 cefotaxime 농도가 절편체 생장에 부정적인 영향을 주지 않으며 배지 내 Agrobacteria를 제거하기에 적절함을 나타내었다. Terpene cyclase 유전자가 재조합된 PILTAB 벡터를 갖는 Agrobacterium tumefaciens LBA4404와의 효과적인 공동배양 기간은 3일간으로 결정되었다. IAA 1.0 mg·L^(-1), BAP 1.0 mg·L^(-1), kanamycin 20 mg·L^(-1) 그리고 cefotaxime 200 mg·L^(-1)를 함유한 선발배지에서 형질전환 된 것으로 여겨지는 신초들이 생산되어 발근을 위해 kanamycin 40 mg·L^(-1)와 cefotaxime 200 mg·L^(-1)이 첨가된 1/2MS 발근배지에 옮겨져 87%의 발근율을 보였다. 발근된 형질전환체들을 대상으로 terpene cyclase 유전자특이 primer를 이용한 PCR 분석이 실시되어 재분화 치커리 내로 1.64 kb 크기의 terpene cyclase 유전자의 성공적인 도입을 확인하였다. This experiment was initiated to optimize factors affecting Agrobacterium-mediated transformation in Cichorium intybus L. cv. Radicchio. The results from the antibiotic sensitivity test for kanamycin and cefotaxime using cotyledon explants of chicory 'Radicchio' suggested that the concentration of kanamycin above 20 mg·L^(-1) might be an appropriate level to make a selection on transgenic shoots possible and 200 mg·L^(-1) of cefotaxime also could be a proper concentration to remove Agrobacteria from the media without any negative effect on explants. The efficient duration for co-cultivation of cotyledon explants with Agrobacterium tumefaciens LBA4404 harboring the recombinant binary vector PILTAB carrying 1.64 kb terpene cyclase gene was decided as 3 days. Putative transgenic shoots were produced on the selection media containing 1.0 mg·L^(-1) IAA, 1.0 mg·L^(-1) BAP, 20 mg·L^(-1) kanamycin, and 200 mg·L^(-1) cefotaxime and transferred to 1/2MS media supplemented with 40 mg·L^(-1) kanamycin and 200 mg·L^(-1) cefotaxime for rooting. The rooting ratio was 63% and putative transgenic plants with roots were obtained. Results from PCR analysis with terpene cyclase gene specific primers confirmed a successful insertion of 1.64 kb terpene cyclase gene into the genomic DNA of the regenerated chicory.

포플라 Callus의 배양환경에 따른 Anthocyanin 생합성

방혜진,이승우,최근원,정인식,설일환 경희대학교 생명자원과학연구원 1997 遺傳工學論文集 Vol.9 No.-

Studies were carried out to investigate the effects of various cultural and environmental conditions on callus growth and anthocyanin biosynthesis of the callus derived from the leaf discs of the Populus hybrid (Populus nigra × Populus maximowiczii cv. Yanghwangchul). Even though the largest amount of anthocyanin was obtained from the calli grown in the vessels illuminated with white fluorescent light, no significant differences in callus growth could be obtained among other vessels illuminated with different light qualities, i.e., red, yellow, blue, green and dark. Callus growth and anthocyanin biosynthesis were promoted by long-day conditions (16-hour photoperiod or longer). The calli grown in Schenk & Hildebrandt (SH) medium continuously (SH→SH) showed the best growth whereas the highest amount of anthocyanin biosynthesis was obtained in the calli grown in SH→SH or SH→White media.

This study has its significance in offering useful basic data for improving amateur boxers' athletic performance by examining which influence the amateur boxers' competition anxiety and self-efficacy have upon athletic performance and by closely examining influence between independent variable and dependent variable. The subjects of this study were 160 players who participated in 「The 64th National Championships & 2011 National Representative Contest」, which was opened at Hongcheon gymnasium in Gangwon-do Province in December 2010. Samples were extracted by using Convenience Sampling Method. A survey tool was used questionnaire. In other words, the construction index was formed with competition anxiety, self-efficacy, athletic performance, and research subjects' demographic characteristic factors. Frequency analysis, correlation analysis, multiple regression analysis, and path analysis of using multiple regression analysis were carried out by utilizing SPSS 15.0ver. The following are the results that were elicited in this study on the basis of the results in research method and data analysis as the above. First, the physical anxiety, which is sub-factor of competition anxiety, was indicated to have significant influence. Cognitive anxiety was indicated to have no influence. Second, exercise efficacy, which is sub-factor of self-efficacy, was indicated to have significant influence. Social efficacy was indicated to have no influence. Third, competition anxiety and self-efficacy were indicated to have direct influence upon athletic performance. Synthesizing these findings, the competition anxiety and self-efficacy were directly strengthening athletic performance. These independent variables can be confirmed to be very important variables immanent in amateur boxers' athletic performance.

AN INVESTIGATION INTO RADIATION LEVELS ASSOCIATED WITH DISMANTLING THE KOREA RESEARCH REACTOR

GEUN-SIK CHOI,HEE REYOUNG KIM,MOON HEE HAN 한국원자력학회 2010 Nuclear Engineering and Technology Vol.42 No.4

We confirmed that the dismantling of two research reactors with thermal power of 2MWth and 100kWth, respectively,reveals no significant difference between the radiation levels of the research reactor site and the surrounding environment far away from it, from the radiation level aspect. Radiation dose and radioactivity were measured at monitoring points around the research reactor site of the Korea Atomic Energy Research Institute (KAERI) in Seoul and comparison points 0.5 km to 3.3km from the site. To grasp trends in the radiation levels during dismantling from the end of 2002 to the end of 2007, the gamma radiation dose rate, the accumulated dose, and the radioactivity of the strontium, tritium, and gamma isotopes were statistically treated and estimated. The averages of these items between the two groups, the research reactor site and comparison points,were assessed by applying a T-test with a significance level of 0.05. P-values found by using the T-test were from 0.12 to 0.83where the values were much higher than the significance level. As a result, no difference was observed between the radiation levels at the research reactor site and at the comparison points by this T-test. This study showed that dismantling activity of the Korea Research Reactor of the Seoul site did not expose the public or the environment to harmful levels of radiation.
