동아시아의 관점에서 본 APEC : 평가와 전망 A Appraisal and Prospect

강승구 大邱大學校 社會科學硏究所 1998 社會科學硏究 Vol.4 No.3

다자적 무역시스템이 원활하게 작동하지 않자 세계경제의 지역주의화가 가속화되고 있다. 지역주의는 다자적 무역시스템에서 해결하고 있지 못하는 뉴-이슈를 빠르게 해결할 수 있는 장점을 가지고 있어 다자적 무역시스템을 보조하는 새로운 방식으로 떠 오르고 있다. 한편 동아시아는 지역주의에 속해 있지 않은 유일한 지역이었다. 그러나 최근에 동아시아는 APEC을 이용하여 글로벌리즘을 촉진함과 동시에 동아시아지역만의 지역화의 가능성의 여지도 남겨 놓음으로써 세계무역시스템에 대한 지덕적 힘(Regional Force)으로서의 위치론 공고히 하고 있다. 이러한 세계무역시스템에서 동아시아가 차지하는 위치는 APEC으로 하여금 '개방적 지역주의' 개념을 채택하게 하였다. 즉 현재 APEC은 완전한 규범적 또는 제도적 경제통합체의 성격보다는 다양한 회원국이 각자 자신의 이해관계에 따라서 무역자유화를 추진하고자 하는 정도에 머물러 있고 이러한 성격은 APEC내 소-지역무역협정간의 다양한 원산지 규정에서도 드러나고 있다. APEC이 제시하고 있는 '개방적 지역주의' 개념은 앞으로 전개될 APEC의 발전방향에 따라서 새롭게 정의되겠지만, 단기적으로 APEC내에 존재하는 소-지역무역협정간의 상이한 원산지규정의 조화 등을 통해서 APEC이 추구하는 WTO와의 일치성은 보다 확장될 것으로 보인다.

An experimental study was designed to analyze the surface reduction effect of ultrapulse carbon dioxide laser on the skin of guinea pigs receiving laser resurfacing. Two squares of skin measuring 3x3 ㎠ were designed on each side of the abdomen of guinea pigs(n=10). Five animals received laser resurfacing on their abdomen at energy of 250mJ/5 watt, and five other animals received 500 mJ/5 watt. On each animal, the left side square was treated with one pass of a CO2 laser, and the right side q=square was treated with two passes using a C.P.G. scanner. The size of the resurfacing area was determined by celluloid overlays at 1,2,3,4 and 6 weeks. Immediately following laser resurfacing, the area was decreased to 69%(left side) and 56%(right side) of the designed area in the 250 mJ/5 watt group, and 59% and 40% in the 500mJ/5 watt group. After 6 weeks, the resurfaced area had been reduced to 70% and 56% of the designed area in the 250mJ/5 watt group, and 60% and 40% in the 500mJ/5 watt group. As a result, the effect of surface reduction by CO2 laser resurfacing increased at a higher power and when more passes of the ultrapulse carbon dioxide laser were applied. The laser treated skin continued to maintain its contracted dimensions. These findings suggest that ultrapulse carbon dioxide laser may be an effective treatment method for rhytides. Another experiment was performed on multiple punch-out lesions on guinea pig skin(n=2) with 1,2,3 mm collimated hand pieces for the purpose of determining a new laser treatment method. After 4 weeks, on gross and histological examination, there were no differences in the healing of multiple punch-out lesions and the healing of punch-out lesions was complete without any scarring. These findings suggest that the laser punch-out method can be used for the treatment of acne scars.

독점?과점·독점적 경쟁 구조 그리고 묵시적 담합 협정은 경쟁정책의 주요한 관심대상이다. 그러나 불완전 경쟁시장에서 나타나는 반-경쟁적 경쟁관행은 항상 후생의 감소를 가져오는 것은 아니다. 사실 경쟁정책의 결정은 복잡한 相反關係를 포함하고 있어, 경쟁법을 per-se-rules로 정형화하거나 경쟁정책의 목적은 단순히 '경쟁수준의 극대화'로 설정하는 것은 바람직하지 않다. 한편 경쟁정책의 주요요소는 수평적·수직적 시장제한, 지배적 지위의 남용, 합병통제 등의 법률제정과 관련된다. 국민 경쟁정책과 무역정책은 상호 많은 관련성을 가진다. 규모에 대한 수확불변·수확체증 그리고 다양한 시장구조에 따라서 경쟁정책과 무역정책은 다양한 형태로 상호 작용한다. 한편 경쟁을 강제하는 범 지구적 무역과 생산요소의 자유화가 확대 되었음에도 불구하고 여전히 경쟁정책의 필요성은 존재하고 있다. 국민 경쟁정책의 집행이 미치는 무역상대국에 대한 負의 효과가 국내 에이전트에 가져다주는 正의 효과를 능가하는 경우 범 지구적인 왜곡이 존재한다고 이야기 할 수 있고, 이러한 경우 경쟁정책의 국제적 조화의 유인은 커지게 된다. 국민 경쟁정책 선택에 의한 왜곡적 상황의 가장 분명한 보기는 각국이 近隣窮乏化 경쟁정책 선택을 억제하고자 하는 공통의 이해관계를 가지고 있음에도 근린궁핍화 정책을 선택하게 되는 '罪囚의 딜레마' 상황이다. 이러한 왜곡적 상황에서 국민 경쟁정책에 대한 국제적 조화가 수행할 수 있는 역할은 근린궁핍화 접근 추구의 가능성을 제한하기 위하여 참가국의 경쟁정책 결과에 관련된 비용과 이득을 변화시키는 것이다.

It is very important to apply the reasonable insulation method to refrigerated warehouse since temperature difference between storage and outside is so great. However, insulation method for refrigerated warehouse is not expressly provided in the Korean building code and there are few examinations for evaluation of each insulation method. Thus, this study aims to evaluate the economical efficiency of the refrigerated warehouse envelope with different insulation method(inside and outside insulation), temperature condition(0℃, -6℃ and -15℃) and insulation thickness(100㎜, 150㎜ and 200㎜ / 50㎜ or 250㎜). As results, it is proved to have the best economical efficiency when outside insulation method with thickness of 100㎜(0℃ and -6℃) and 150㎜ urethane(-15℃) is applied.

본 연구에서는 하수 처리장에서 발생되는 상당량의 폐 슬러지를 전처리 없이 중금속 제거에 사용하였다. 본 연구의 목적은 폐 슬러지를 이용하여 중금속을 제거하는 것이다. 온도와 pH, 초기 농도의 영향과 보관 시간에 따른 납 흡착량의 영항을 흡착등온 모델과 흡착속도 모델에 적용시켜 활성슬러지의 납 흡착 특성을 고찰하였다. 납, 카드뮴, 크롬, 니켈 중 슬러지는 납을 가장 많이 제거하였고, pH 4.5~5.5에서 최대의 흡착량을 나타냈으며, 온도가 증가할수록 흡착량은 증가하였고, Langmuir model에 잘 적용되었으며, 초기 최대 흡착속도도 Michaelis-Menten 형태 식으로부터 구하였다. In sewage treatment plant, waste sludge was one of bothering thing to be treated. The objective of this study was to examine the removal of heavy metal by waste sludge. The effect of factors such as temperature, pH, storage time, initial concentration of lead, and initial amount of biomass on adsorption of lead was investigated. And the biosorption model, adsorption isotherm, and initial adsorption rate model were evaluated. Waste sludge was proved to have an excellent ability to remove lead than other heavy metals such as cadmium, chromium, nickel in pure and mixed solution. The optimum pH of biosorption with waste sludge was 4.5~5.5, and the amount of adsorption was increased with increasing temperature. The adsorption isotherm of lead to waste sludge followed to Langmuir model. The initial adsorption rate of lead to waste sludge followed to Michaelis-Menten type kinetic.

Previous studies have been indicating that the various mandibular forms were all related to each other with functional framework, and analyses have been showing that the mandibular changes closely corresponded to, and resulted from, the overall pattern of craniofacial structures. This study was aimed to identify the morphologic characteristics of the adult mandible amongst each classes of malocclusion. Lateral cephalograms of 74 class I (0-3 degrees of ANB), 108 class II (over 3 degrees of ANB) and 90 class III (below ()degree of ANB) malocclusion were employed to digitize and statistically analyze through the angular measurements and tie computation of size ratios. The following results and conclusion were drawn; 1. There computed no typical difference on mandibular form between the scope of the vertical and horizontal composition of classifications. 2. The greatest curvature formed by the corpus and the ramus was found in class III group. 3. The size ratio of the corpus to ramus was the highest in class III, then followed by the class II and class I in order. 4. The class III manifested the most outstanding ratios of longtitude to breadth in the ramus, and latitude to height in the corpus. 5. The class HE got the most prominent symphysis, in contrast that the class II showed the least. 6. The class I revealed the minimum difference of height in anterior and posterior part of the corpus. 7. The flexion in the crust of the mandible set the deepest at supramental area in the class If, on the top of that no significant differences on the posterior border of the ramus and lower border of the corpus among 3. groups. It forced to conclude the class III got the longer corpus and ramus length than any other group and the higher ratio of corpus to ramus in length as well. The class III attributed somewhat to the absolute size of the mandible.

This paper introduces a new zinc coated copper wire electrode with coiled cone shape which has low surface resistance and tolerance to the motion artifact for promontory stimulation electrically auditory brainstem responses (PSEABR). Auditory brainstem responses (ABR) can be used to predict hearing threshold level with a great deal of accuracy particularly for a young child who cannot cooperate mechanically and some hearing impaired who are exaggerating a hearing loss for economic compensation. While severe profound sensorineural hearing losses may not be implemented by auditory potentials, PSEABR is proven as a useful tool even for some sensorineural related hearing impaired. It was shown that PSEABR gives the electrical stimuli to promontory of the cochlear instead of giving acoustic stimuli. For this reason, PSEABR can be used as an alternative for cochlear implantation, and can also be used as an optimal device selection and neural information for MAP. It was found that the role of electrode is very important in PSEABR. Even though this cone-shaped electrode was applied in animal experiments, waveforms are well produced by PSEABR. Thus, it was concluded that cone-shaped electrode turned out to be a useful preoperative audiological evaluation tool in deciding time for cochlear implantation surgery.
