This paper aims at investigating the developments and challenges of Northwest Pacific Action Plan (NOWPAP), a regional cooperation mechanism to protect marine environment in Northeast Asia. As one of 16 UNEP's Regional Seas Program, NOWPAP has evolved since its inception in 1994. Based on the belief that a cooperative institution may work more efficiently to address common regional concerns on marine environment, China, Japan, Russia and South Korea have developed NOWPAP under the UNEP's leadership. NOWPAP now has its own independent secretariat, and 4 regional activity centers while expanding its partnership with other institutions. However, NOWPAP must address several challenges that it now faces for better achievement of its goals. They include consideration of unique geopolitical situation in this region, participation of North Korea, incorporation of sustainable development concept in its activities, reconsideration of equal opportunity principle for more efficient cooperation, and securing sufficient financial resources.

The purpose of this studies was analyzed moisture content, rheology and sensual test of jujube jungkwa by addition of water, sugar, fructose at processing of jujube jungkwa for development the optimization for processing of jujube jungkwa. The changes of moisture contents at process condition of jujube jungkwa were increased by increasing of sugar and water quantity. And moisture contents of jujube jungkwa were increased by high fructose quantity and low sugar quantity, but were decreased by high sugar and fructose quantity. The 'b' values of jujube jungkwa at low sugar quantity were decreased by the increasing of water quantity, but increased at high sugar quantity. The cohesiveness of jujube jungkwa at 0.03 kg of fructose were high by the increasing of sugar quantity, but those at 0.065 kg of fructose were high by the decreasing of sugar quantity. And those at 0.050 kg of fructose were similar without the quantity of sugar. The sweet taste of jujube jungkwa were increased by the increasing of water and fructose quantity. The characteristics of jungkwa at conditions of processing for the best quality of jujube jungkwa were 18-20% of moisture content, 2.0-3.0 of 'b' values, 3.0-3.2 of color scores, and 3.3-3.4 of sweet taste scores. The conditions of processing for the best quality of jujube jungkwa were determined to 0.95-1.04 L of water, 0.052-0.060 kg of fructose at 0.95 kg of sugar.

Latent fingerprint left on the adhesive sides of tapes can be easily found at a crime scene. Small Particle Reagents(SPR) based on iron oxide($Fe_3O_4$) is a technique for the detection of a latent fingerprint adhesive surface. In this study, found out that the causes affecting the quality of the fingerprints developed when used SPR based on iron oxide. To a suspension of 0.5g of iron oxide in 100ml of distilled water, 0.5ml or more surfactant were added can be developed latent fingerprints of good quality. In addition, using surfactants HLB(hydrophile-lipophile balance) value of 11~18 showed good contrast to the background and latent fingerprint.

The furfural, generated by decomposition of insulating paper, the amount of metal in insulating oil, and tano(electrical properties of insulating oil)have been studied for the insulating oil in pole transformer with accelarated thermal aging test. It has been found that tan $\delta$ is affected by adding components of the transformer. The examination of amount of metal, which exhibits catalytic behavior to oxidation of insulating oil, suggested that the amounts of copper increase with degradation time. A comparison between tano and copper amount suggested that the amounts of copper for attention are above 0.2[pp]). Finally, the examination of amount of furfural revealed that the amounts of furfural increase with degradation time. As a consequence, these results could be used for diagnosis of pole transformer.former.

Bob Hale recently proposed a theory of real numbers based on abstraction principles. In his theory, real numbers are regarded as ratios of quantities and the criteria of identities of ratios of quantities are given by an Eudoxan ratio principle. The reason why Hale defines real numbers as ratios of quantities is that he wants to satisfy Frege's requirement that arithmetical concepts should be defined to be adequate for their universal applicability. In this paper I show why Hale's explanation of applications of real numbers fails to satisfy Frege's requirement, and I propose an alternative explanation. At first I show that there are some gaps between his explanation of the concept of quantity and his stipulation of domains of quantities, and that those gaps give rise to some difficulties in his explanation of applications of real numbers. Secondly I introduce a new ratio principle which can be applied to any kinds of quantities, and I argue that it allows us an adequate explanation of the reason why real numbers as ratios of quantities can be universally applicable. Finally I enquire into some procedures of the measurement of quantities, and I propose some principles which we should presuppose in order to successfully apply real numbers to the measurement of quantities.

작물보호제를 보는 세간의 이목을 보노라면 대개는 내용이 퍽 독단적이고 감정적이며 과장된 표현이 적지 않음을 알 수 있다. 그럼에도 이런 평가를 접하는 대중들은 이것이 진실이라고 믿는 사람도 있을 것이다. 그것은 곧 세론(世論)을 이루게 되어 종국에는 작보제의 진실인 양 왜곡의 길을 걷는다. 비록 우리나라의 예는 아니지만, 이 같은 세간의 잘못된 지적과 평가에 대해 바로잡는 내용이 있어 인용해 본다. 올바른 인식을 갖는 호기가 되길 바란다.

최근에 cobalt-phosphate는 물을 분해하는 전기화학적 촉매로서 활발한 연구가 진행되고 있다. 우리는 간단히 염기의 양을 조절함으로서 cobalt-phosphate의 형태를 제어하였다. 염기의 양이 증가함에 따라 두께가 10 nm 이하의 얇고 입자 작은 판 모양에서 점점 두껍고 큰 판의 모양으로 변해감을 확인 할 수 있었다. 이들을 sodium-borohydride를 이용한 수소 발생실험의 촉매로 사용하였을 때 두께가 10 nm 이하의 입자가 작은 판 모양에서 높은 촉매 활성을 확인 할 수 있었다.

문서 분류나 여과 문제에서 양의 학습 데이터의 부족은 성능 저하의 주요 원인이 된다. 이런 경우 여러 학습 알고리즘이 문제의 특성을 제대로 파악하지 못한다. 본 논문에서는 부스팅 기법을 도입하여 이 문제를 접근해 보았다. 부스팅 기법은 약한 능력을 보유한 학습 알고리즘을 부스팅 과정을 통해 궁극적으로 강력한 성능을 얻을 수 있게 해준다. 간단한 선형 퍼셉트론에 부스팅 기법을 도입하여 문서 여과에 적용하였다. 제안된 알고리즘을 Reuters-21578 문서 집합에 적용한 결과, 재현률 측면에서 다층 신경망보다 우수한 성능을 보였고 특히 양의 학습 데이터가 부족한 문제의 경우 탁월한 결과를 얻을 수 있었다.

전남대학교는 사회적 요구, 수요자 중심의 교육과 연구 체계로의 변화, 사회 필요의 인력 양성을 위하여 통합을 통해 지역 사회 요구에 부응하는 강력한 하나의 국립대를 구현하였다. 통합으로 인한 구조 변화의 유도는 지역 혁신의 핵심 중추로서 기여도가 증대될 것이며, 거버넌스의 통합에 따라 대학 운용 비용을 줄여 재정 효율화를 기할 수 있다. 또한 양 캠퍼스 간 자원의 공동 활용, 단과대학 및 학부(과)의 통폐합을 통해 인적.물적 자원의 증대를 기할 수 있게 되었다. 반면 통합에 대한 부정적 영향에 대한 해결은 양 대학의 적극적인 배려뿐만 아니라 정부의 일관성 있는 정책 실현과 정책 추진을 위한 법제화가 필요하며, 무엇보다도 충분한 재정의 절대적 지원이 필요하다고 본다.
