GMO를 취급(dealings)형태에 따라서 면제(exemption), 위험이 매우적은 취급(notifiable low risk dealing), 면허(licensing), 등록(register)의 4가지로 분류하여 감독함 4. GM식품의 안전성 심사는 호ㆍ뉴식품청(Australia New Zealand Food Authority, ANZFA)에서 관장하며 호주식품 강령 기준 18(Standard A18 of the Australian Food Standards Code)이 근거 법임 5. ANZFA에서는 제초제 저항성 콩, 옥수수, 면화, 감자, 카놀라 등 6작물 12종의 GM작물에 대하여 식품안정성 확인을 완료함 6. 호주에서는 2001년 12월 7일부터 유전자변형식품의 의무 표시제를 시행하고 있으며 비의도적 혼입 허용치는 1%로 설정함 As Australia's new national gene technology regulatory system began on 21 June 2001, the Office of the Gene Technology Regulator (OGTR) was newly established to regulate GMO related research and GM products throughout the nation. "Gene Technology Act 2000" is the statutory basis the new regulatory system. The OGTR is within the Commonwealth Department of Health and Aged Care, responsible for overseeing the gene technology research and development including the GMO field trials across Australia. For the regulation of genetically modified food, the Australia New Zealand Food Authority(ANZFA) is responsible for developing and reviewing national food standards. All foods available for sale in Australia and New Zealand must comply with the relevant national food standards. ANZFA also responsible for carrying out safety assessments of GM foods on behalf of the Commonwealth, State and Territory Governments of Australia and the Government of New Zealand. The ANZFA's safety assessment process for GM foods is based on concepts and principles that have been developed through international organizations such as the World Health Organization(WHO) and the Food and Agriculture Organization(FAO) and the Organization for Economic Co-operation and Development(OECD). Mandatory labelling of GM foods containing either introduced DNA or protein in the final food came into effect on 7 December, 2001.

채성산 대전대학교 기초과학연구소 2000 自然科學 Vol.11 No.2

본 연구는 p-차원 자료의 구조를 파악하고, 관련이 있는 변수들을 의미있는 변수들의 집합인 q-차원(q≤p)으로 축소 시 주성분인자분석방법을 적용하였다. 인자분석의 적용 결과로 생성되는 자료에 대하여 판별분석과 군집분석을 동시적으로 실시한 후, 군집분석으로 형성된 선행군집자료에 판별분석을 적용하여 적정분류율을 계산하였다. 이때, 의미있게 축소된 자료에 대한 판별분석의 적용 시 군집방법의 활용성에 대하여 살펴보았다. Principal factor analysis is applied to reduce p-dlmensions into q-dlmensions (q≤p). Any partition of a collection of data points with p and q variables generated by the application of eight hierarchical clustering methods was re-classified by dlscriminant analysis. Then correct classification ratios are obtained for the application of dlscriminant analysis through each clustering method and the direct application of discriminant analysis. By comparing the correct classification ratios, the applicability of cluster analysis and discriminant analysis was considered.

In order to compare and analyze major techniques employed by the college judo competitors of Korea who participated in the 43rd National Male and Female Judo Championships by Weight Class, the players in the light, middle and heavy weight classes were classified into 3 categories: (1) those who are taller than opponents(by +4 cm or more); (2) as tall as opponents(-3 +3 cm); and (3) smaller than opponents(by -4 cm or less). Scoring points and used techniques were examined from videotapes and matching records, which resulted in the following conclusions: 1. In case of light weight players who are taller than opponents, foot(34.73%) was used most frequently and effectively, followed significantly by hand(28.54%), pressing(15.35%), waist(15.31%) and pull-down(4.25%) sacrifice throw techniques(l.66%) in order(p<0.001). Those who are as tall as opponents used foot techniques(34.88%) more effectively than hand although hand techniques(38.38%) were employed more frequently. For those who are smaller than opponents, hand techniques(35.03%) were used most frequently and effectively, followed significantly by foot(32.57%), waist(8.39%), pressing(16.12%) and pull-down sacrifice throw techniques(7.8%) sequence(p<.001). 2. In case of middle weight players who are taller than or as tall as opponents, foot(30.72%) was used most frequently and effectively, followed significantly by hand(35.42%), pressing(21,32%), waist(8.15%), pull-down sacrifice throw(0.42%) and cross lock(l.06%) in order(p<0.00l). However, for those who are smaller than opponents, hand techniques were used more frequently and effectively than pressing, waist and cross lock techniques(p<.00l). 3. In case of heavy weight players who are taller than opponents, foot(40.95%) was used most frequently but hand techniques(24.76%), pressing(20.63%), waist(12.38%), pull-down sacrifice throw and cross lock were used frequently in order (p<.001). Whereas, for those who are as tall as or smaller than opponents, such techniques as hand(30.57%), foot(28.43%), pressing(24.73%), waist(l0.52%), pull-down sacrifice throw(1.85%), cross lock(l.66%) and shoulder throw (0.24%) were used frequently in order(p<.001) but foot(31.92%), hand(28.46%), pressing(24.62%) and waist techniques(13.08%) and cross lock (1.92%) in sequence appeared to be favorable for scoring(p<.001). From the conclusions as above, it became evident that most players, regardless weight class, preferred hand techniques in a series of shoulder throw and back throw, too. In case, however, opponents are taller than players, foot techniques were employed preferably and pressing was also favored out of cross strangle techniques, while pull-down sacrifice throw, waist, pressing and cross lock techniques were drastically less used compared to other shoulder throw techniques. Based on the findings of this study, it seems advisable to improve judo techniques more qualitatively and to train outstanding players more quantitatively by helping promote competition ability of players, learn better effective defending actions, research and develop new techniques and train repeatedly and periodically to use them more effectively and appropriately.

본 연구는 p-변량 자료의 구조를 파악하고, 관련이 있는 변수들을 p보다 적은q-차원(p≥q)으로 축소하였을 경우, 자료에 존재하는 군집수의 예측에 어떤 영향이 있는지 비교 분석하였다. q-차원으로 축소시, 주성분인자분석을 사용하였다. Cluster analysis is a primitive technique in which no assumptions are made concerning the data structure. A method predicting the number of cluster by using dimensional reduction is suggested with Rand's(1971) C? k=1,2 …, n-1, statistic. The principal factor analysis is used to reduce original p-variables into new q-variables(p≥q). simulation is conducted to compare the suggested method.

Perinatal asphyxia is one of the most important factors contributing to neonatal morbidity and mortality. However, no clear-cut parameters exist which enable an early identification of neonates who are at risk to develop brain damage. We measured creatine kinase(CK), CK isoenzyme, AST, ALT, LDH in full term asphyxiated(n=35) and healthy(n=39) newborns at 6-10 hours after birth to establish the values of these enzymes in the retrospective diagnosis of asphyxia and if serum levels of these enzymes correlated with the abnormalities of neurosonography or auditory evoked potential. The asphyxiated newborns had significantly increased serum activities of CK-BB(93.5±160.8 IU/L) and CK-BB%(11.1±12.4%) compare to controls(39.2±37.2 IU/L, 3.9±3.4%). However, there were no significant differences in the enzyme activities between normal and abnormal groups of neurosonography or auditory evoked potential. It is concluded that elevated CK-BB and CK-BB% are reliable indicator of the neonatal asphyxia. But the predictive value of specific enzymes for the development of neurologic disorders is not clear. Prospective long-term follow up studies are necessary to evaluate the predictive value of enzyme activities for the neurologic outcome.

Purpose: To introduce novel findings of polypoidal choroidal vasculopathy (PCV) via optical coherence tomographyangiography (OCTA)Methods: This study is a retrospective chart review of 16 patients (16 eyes) with PCV. OCTA (Avanti RTVue XR)findings were evaluated and selected for analysis after agreement by two retina specialists . Results: Twenty one polyps in 16 eyes (16 patients) with PCV were included in this study. The mean patientage was 67 years (13 men and three women). The shape of polypoidal lesions on OCTA at initial were halo(five polyps), rosette (seven polyps), and vascular network (nine polyps). Eight months after anti-vascular endothelialgrowth factor treatment, in a total of four eyes, seven polyps could be followed up completely, thetwo halo type polypoidal lesions changed to rosette and vascular network type. The lesions of three rosetteand two vascular network type lesions did not change in shape. In addition, the size of the polypoidal lesions(one among two halo types, two among three rosette types, and two among two vascular network types) decreased,but one halo type did not change and one rosette type increased in size on OCTA. Conclusions: En-face OCTA enabled us to categorize novel types of PCV with polypoidal lesions.

Purpose: To determine the diurnal variation in choroidal thickness and choriocapillaris flow measured by optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) Methods: This study was a prospective study of 15 normal, young volunteers (30 eyes) who underwent OCT and OCTA examination 5 times a day at 2-hour intervals. Choroidal and choriocapillaris thicknesses were measured with the enhanced depth imaging mode of OCT. The area of flow was measured in 1-, 3-, and 6-mm-diameter areas centered at the fovea and analyzed with the split-spectrum amplitude- decorrelation angiography algorithm of OCTA. Choroidal and choriocapillaris thicknesses and flows were analyzed independently by two vitreoretinal specialists. Results: Choroidal thickness showed a significant diurnal variation. The maximum thickness was 311.31 μm at 9 a.m., and the minimum thickness was 266.75 μm at 5 p.m. (p < 0.001). In contrast, the mean choriocapillaris thickness was 15.14 μm, and remained relatively constant without a significant diurnal variation (p = 0.694). The mean choriocapillaris flow area was 0.45 mm2 (p = 0.238) in a 1 mm area, 4.22 mm2 (p = 0.230) in a 3-mm diameter area, and 16.94 mm2 (p = 0.062) in a 6-mm diameter area. No diurnal variation was observed. Conclusions: Despite significant diurnal variation in choroidal thickness, choriocapillaris thickness and flow remained relatively constant over time.
