오용성,차재경,곽준혁 한국목재공학회 2002 목재공학 Vol.30 No.4

현재 폐목재의 발생량은 국내의 연간 목재사용량의 40% 정도의 수준으로 국내의 목재자급율을 고려해볼 때, 목재패널산업에서의 이런 폐목재의 재활용은 많이 장려되어야 한다. 본 연구는 폐목재로부터 얻어진 파티클과 실험실에서 합성한 요소수지를 폐목재파티클의 전건무게에 대해 6% 첨가하여 열압온도 162℃와 열압시간 5분에서 파티클보드를 제조하고 ASTM D 1037 방법에 의해 파티클보드의 성능을 평가하였다. 파티클보드의 성능을 평가한 결과는 KS F 3104 파티클보드 8.0형의 최소요구를 만족시키는 것이다. 이런 파티클보드의 성능평가 결과는 폐목재가 파티클보드의 원료로 적합하다는 것을 보여준다. The generation of wastewood is currently about 40% level of the amount of domestic wood use. When the rate of wood self-supply is considered, the recycling of wastewood in wood panel products industry should be encouraged. This study was evaluated the performance of particleboard (PB) made from wastewood. PBs were manufactured with the synthesized urea-formaldehyde resin at 5 minutes hot-press time, and at 162℃ press temperature with 6 percent resin solids level on an ovendry wastewood particle weight basis. The PBs were tested by the procedure of ASTM D 1037. Test results exceeded the minimum strength requirement according to KS F 3104 Particleboard type 8.0. The PB's performance showed that wastewood is suitable raw material for PB.

Although the role of surgical management of metastatic disease from primary carcinoma of the coln and recutm is still controversial, resection of hepatic metastasis improves survival rate of patients with primary colorectal carcinoma treated locally. The lung is the most common site of extra-abdominal metastasis following resection of a prymary colorectal tumor and not amenable to curative therapy. It is possible to resect the pulmonary metastasis in selected patients following resection of colorectal cancers, but the 5-year survival rates are ranged from 9% to 57%. Authors report a case of resection of pulmonary metastasis occured 3 years after resection of primary colon carcinoma.

중국 아편전쟁박물관의 전시콘텐츠와 역할

오일환,김준혁 인문콘텐츠학회 2015 인문콘텐츠 Vol.0 No.38

본 논문은 중국의 아편전쟁 관련 박물관과 기념관을 중심으로 전쟁의 기억을 재현하는 전시콘텐츠와 특징을 고찰하고 기념활동, 지역순회 전시 및 교육프로그램 등 다양한 교육콘텐츠로 재구성하여 활성화하는 역할에 대하여 연구하였다. 중국은 개혁개방 이 후 급격한 경제적 변화로 관리가 소홀하였던 문화유산에 대하여 전통보존과 중화민족의 역사적 정통성을 계승하기 위한 대규모의 기념관과 박물관을 건립하였고 전통보존과 중화민족의 역사적 정통성을 계승하기 위하여 청소년뿐 아니라 일반인 대상의 사회교육 활동을 더욱 강화해 나아가고 있다. 그리고 근현대사의 혁명유적지와 야외 문화유산을 대대적으로 복원 정비하면서 전국 중점문물 보호단위의 애국주의 교육기지로 지정하고 있다. 아편전쟁박물관이 자리하고 있는 광동성은 영남문화의 발상지이며 주강지역의 경제권의 중심지로서 홍콩과 마카오의 반환으로 서구 식민지의 잔재를 청산하고 중국몽을 이루기 위한 시진핑의 일대일로정책에서 21세기 해상실크로드의 핵심지역이다. 이러한 과거의 역사적 사실을 기억의 표현으로 전시하는 아편전쟁박물관은 서양 제국의 부도덕한 아편무역과 불평등한 조약 그리고 치욕적인 침탈의 집단기억을 극복하고 중화민족의 부흥과 애국주의를 함양하기 위한 기념물과 전시시설의 재현공간이다. 또한 전시기념물의 다양한 전시콘텐츠를 교육활동과 교육프로그램의 교육콘텐츠로 재구성하여 아편의 폐해방지 교육을 비롯하여 전쟁의 기억과 근대의 역사인식을 애국주의 공간과 관광자원으로 활용하고 있다. This study investigated exhibition contents and characteristics focusing on the museum and memorial relating to the Opium Wars in China and examined diverse memorial activities, exhibitions and educational activities. China has built large-scale memorial and museum to preserve cultural heritage which has been poorly managed under rapid economic changes after the reform and opening and keep the historical legitimacy of Chinese people. To preserve tradition and inherit its historical legitimacy, China has also strengthened social education against the general public as well as adolescents. For this, the revolution site and outdoor cultural heritage from the modern and contemporary history of China have been comprehensively restored and designated as the base for patriotic education. Guangdong Province where the Opium War Museum is situated is the cradle of southern culture and economic center of the Pearl River region. In fact, it is a key region for the 21st Century Maritime Silk Road in the ‘One Belt, One Road’ initiative launched by President Xi Jinping, which was aimed to banish the vestiges of Western colonial rule and build ‘Chinese Dream’ after the return of Hong Kong and Macau to Chinese sovereignty. The Opium War Museum is a space where the memorials and exhibition facilities aimed to overcome the collective memories of the Western Empire’s immoral opium trade, unequal treaty and shameful invasion, restore the glory of Chinese people and raise patriotism are reproduced. The diverse activities and exhibition contents of the museum are used to give education on the prevention of the evil influence of opium, and the war memory and historical awareness are used as tourism resources.

오용성,곽준혁 한국목재공학회 2003 목재공학 Vol.31 No.1

증량제로서 카제인과 콩을 첨가한 요소수지 접착제와 소나무 간벌재 파티클로 실험실 파티클보드를 제조하였다. 소나무 간벌재 파티클로 제조된 파티클보드를 성능 평가한 결과 소나무 간벌재는 파티클보드의 원료로서 적합하다. 증량된 요소수지로 접착된 파티클보드는 증량제의 첨가량이 증가함에 따라 기계적인 성능은 감소하는 경향이었다. 그러나 요소수지 접착제의 고형분량에 대해 카제인은 15%까지 콩은 20%까지 첨가하여 파티클보드 제조에 사용할 수 있다. Particleboards (PBs) were made from pinus densiflora thinning particle with urea-formaldehyde (UF) resin added casein and soybean as extender. The performance test results of the PB made showed that Pinus densiflora thinning log was suitable raw material for PB. As the extender addition in the UF resin was increased, the mechanical performance of the PB, bonded with the extended UF resin, were significantly decreased. However, casein and soybean can be used up to 15% and 20% of the UF resin solids resectively.

곽준혁,오용성 한국목재공학회 2004 목재공학 Vol.32 No.1

은수원사시나무 파티클과 저밀도 폴리에틸렌을 50:50, 60:40, 70:30의 3종류 혼합비율로 열압온도 145℃와 열압시간 5분에서 목질플라스틱패널을 제조하였다. 본 연구에서 목질플라스틱패널을 제조하는데 왁스와 접착제 등 어떤 첨가제도 사용하지 않았다. 제조한 목질플라스틱패널의 밀도, 박리강도, 휨탄성계수, 휨파괴계수, 두께팽창률 및 물흡수율에 대한 성질을 측정하여 패널의 성능을 평가하였다. 성능평가한 data를 SAS programing package에 의해 통계분석한 결과에 의하면 목질플라스틱패널의 박리강도, 휨파괴계수 등의 성질은 목재/폴리에틸렌 혼합비율이 50:50으로 제조된 패널이 다른 혼합비율인 60:40과 70:30으로 제조된 패널보다 5% 수준에서 높게 나타났다. 목질플라스틱패널의 치수안정화를 기준으로 볼 때, 목재/폴리에틸렌 최적의 혼합 비율이 60:40이라는 결과를 보여줬다. Wood/polyethylene panels were manufactured from Populus alba × glandulosa particles and low density polyethylene particles at three mixing rates, 50:50, 60:40, and 70:30. A total of 15 wood/polyethylene panels was made at 145 C and 5 minutes hot-press time. Wood/polyethylene panels were tested for internal bond, bending, and dimensional stabilities such as thickness swell and water absorption. Panel performance data were analyzed using the SAS programing package. The test results of the wood/polyethylene panels showed that as the polyethylene mixing rates were increased, the panel property values increased Based on panels' dimensional stabilities, the optimum wood/polyethylene mixing ratio appeared to be 60:40.

This paper aims to make clear the fundamental differences between the constitutions of two political systems, constitutional democracy and communism. (1) Fundamental Human Rights The recognition and the protection of fundamental liberties are the essences of the political system of constitutional democacy. The reality of individual liberties is the only reliable criterion that differentiates the two political systems, since the institutional apparatus of both government, assemblies, elections, parties, bureaucracies have become stereotyped to the point of identity. Recognition or nonrecognition of fundemental guaranties are closely related to the ideological telos of either system. In the constitutional democracy they crystallize the supreme values of human self-realization and dignity. In the communist states they are denied legitimacy not only because they may function as foci of opposition against monolithic power but also because they could obstruct the ideology of economic planning under collectivism. The idelolgical foundation and functional purpose of classical fundamentalism underwent a fa -reaching transformation in the Marxian society. The Russian Revolution preaches and practices the primacy of the collectivity over the individual. Instesd of being "inalienable" interpreted as obligations of the state toward the laboring masses. The attitude of Marxism in the U.S.S.R. and the so-called "People's Democracies" toward fundamental liberties is altogether different. All constitutions in the Soviet orbit contain elaborate statements on fundamental rights of the citizens, characteristically coupled with provisions concerning their duties toword the state and the community. Civil liberties in the classical sense, which the constitution of communist states merely summarizes, are overshadowed by the new social and economic rights. The guaranty of the civil rights proper is hedged in by the rubber clause that they are guaranteed " in conformity with the interests of the working class" and "in order to strenghthen the socialist system". Especially political rights of the suffrage are converted into compulsory mass participation in the political process directed by the party hierarchy. And its single party (communist party)was the straight negation of all political liberty. (2) Patterns of Governament In the modern democratic-constitutional state the essence of the power process consists in the attempt to establish an equilibrium between the various competitive plural forces within in state society, with due regard to the free unfolding of the human personality. In communist state, social control and political power are monopolized by a single power holder, subordinating the individual to the ideological requirements of the group domination the state. The basic difference between the two political systema conists in whether, in the various stages of the governmental process, political power, is distributed among and shared by several independent power holders or whether political power is concentrated in and monoploized by a single power holder, be it an individual person, and assembly, or a party. Assembly government system revived in the Stalin constitution of 1936 in the U.S.S.R. from where it spread, after the Second World War, to all satellite states, as well as East Germany, Red China, North Korea. No communist state fails to conform to this standard pattern. Assembly government, by its own biological laws. easily transforms itself into a regime in which a single power holder exercises the monopoly of political power. This may well be the intrinsic reason for the communist preference. By necessity the communist state is a plice state. Another indispensable instrument of social control is the single party. The governmental techniques of a communist regime are necessarily authoritarian. But the regime does much more than exclude the power addressees from their legitimate share in the formation of the will of the state. It attempts to mold the private life, the soul, the spirit and the mores of the citizens to a dominant ideology that the various instrumentalities of the power process force on the non-conformists.
