본 논문에서는 ESPI 시스템을 이용하여 복합재료 구조물의 인위, 자연 결함을 검출하였다. 복합재료 구조물에서의 ESPI의 적용성을 알아보기 위해 복합재료 적층판 시험편, 하니컴 구조물 시험편, 접착조인트 시험편을 사용하였다. 결함을 검출하기 위해 시편의 표면변형을 쉽게 발생시킬 수 있는 열하중법을 선택하였다. 실험경과는 ESPI를 이용하여 복합재료 구조물의 결함을 쉽게 검출할 수 있고, 다른 여러 복합재료 구조물의 결함의 검출에도 적용할 수 있음을 확인하였다. In this paper, artificial and real defects(delamination and debond) in composite structures were detected by using ESPI system. There types of specimens, that is, composite laminates, honeycomb structures, and adhesive joints, were used to study the applicability of ESPI to composite structures. To detect defects in specimens, we selected thermal loading method that can easily induce the surface deformation of specimen. Experimental results show that defects in composite structures could be easily detected by ESPI. Moreover, it shows that ESPI could be usefully applied to the detection of defects of defects in various composite structures.

Platelet-Derived Growth Factor가 백서두개관 세포군의 증식 및 교원합성에 미치는 영향

김기수,고성희,백정화,민병무,김관식,정동균 대한구강생물학회 1991 International Journal of Oral Biology Vol.15 No.2

To study the effect of platelet-derived growth factor(PDGF) on the replication and collagen synthesis of rat calvarial cells, five bone cell populations(I-V) were prepared from fetal rat calvaria by sequential enzyme digestion. After primary culture for 6-7 days, each bone cell population was collected and then population Ⅰ and Ⅱ, Ⅳ and Ⅴ were pooled together. And the cells were resuspended at 6-8×10^4 cells/㎝^2 and cultured for 2-3 days. The medium was changed to serum-free medium prior to addition of growth factor. The effect of PDGF on the cell proliferation was measured by the incorporation of [^3H]thymidine into DNA. Protein synthesis was determined by measurement of [^3H]proline incorporation into collagenase-digestible protein(CDP) and noncollagenous protein(NCP) according to the method of Peterkofsky and Die-gelmann(1971). The observed results were as follows. 1. PDGF at 10 ng/㎖ significantly increased the [^3H]thymidine incorporation into DNA in all bone cell populations. 2. PDGF at 30 ng/㎖ significantly increased the synthesis of NCP in population Ⅰ, Ⅱ and Ⅳ, Ⅴ. 3. PDGF had no effect on the synthesis of CDP but percent collagen synthesis was decreased significantly in population Ⅳ, Ⅴ. Taken together, the increase of protein synthesis by PDGF in rat calvarial cells was due to the incraese of NCP synthesis.

比較憲法에 관한 硏究 : 民主主義國家의 憲法과 共産主義國家의 憲法을 中心으로

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.

Response Matrix 에 의한 감마線 Spectrum 및 그 照射線量 解析

金成冠,田載植 대한방사선 방어학회 1986 방사선방어학회지 Vol.11 No.1

3'×3' 원통형 NaI(T1) 검출기와 多重波高分錫器를 사용하여 측정한 0.05~2.0MeV 구간의 γ선 spectrum에서 實spectrum을 구하기 위하여 照射線量率산출에 편리한 response matrix방법을 사용하였다. Response matrix구성에는, 위의 에너지 구간을 0.1MeV의 등간격으로 나눈 20×20 matrix로 한것과 검출기의 분해능이 입사 γ선 에너지의 平方根에 의존한다는 가정하에 0.1(MeV)?구간으로 나누어 14×14matrix로 구성한, 두가지 방법을 사용하였으며 그 逆matrix들은 P-E82/32콤퓨터로 계산하였다. 이 방법으로 얻은 조사선량율은 에너지와 flux가 알려진 γ선場에 대하여 흔히 사용되는 계산방법으로 구한값과 10% 이내에서 일치하고 있으며, 線量測定學的 견지에서는 E? 구간으로 형성된 matrix가 등에너지간격으로 구성된 것보다 현실적인 것으로 판단되었다. A study has been carried out for figuring out real photon spectrum from an observed gamma-ray spectrum by means of response matrix method, which is known ofe of the relatively convenient method for the estimation of exposure rate of a complex gamma ray field in comparison with graphical analysis and least square fitting of the measured spectrum. A 3"×3" cylindrical Nal(T1) scintillation detector in association with multichannel pulse height analyzer and six reference gamma ray sources covering the photon energy range of 0.05 to 2.0 MeV were used. In dividing the energy region for the construction of response matrix, two different approaches were attempted. One is dividing the entire energy region of interest into 20 bins, one of which corresponds to a width of 0.1 MeV to form 20×20 matrix, and another is dividing the 2MeV region into 14 bins to form 14×14 matrix consists of 0.1(MeV)? Intervals assuming the resolution of the detector is dependent on square root of the incident photon energy. Inversion of thus constructed matrices was performed by a computer(P-E8/32) using the program attached to the end of this paper. The resultant exposure rates obtained by this method were in good agreement, within 10% with those calculated by ordinary formula widely used for a gamma-ray field of known energy and flux. It is concluded that the photen flux obtained by the response matrix constructed under the assumption of E? dependence is more realistic than that obtained by the matrix consist of identical energy bins in dosimetrical point of view.

로드셀을 이용한 고속 감자 중량계량법

김상철,임종환,김귀식,김성근,양종훈 제주대학교 공과대학 첨단기술연구소 2001 尖端技術硏究所論文集 Vol.12 No.2

Potatos, together with tangerines, are one of the major agricultural products in Jeju, and the production account for more than 30% of the domestic production. Recently some kinds of sorting machine for potatos are available, but they are not extensively used because their performance is not satisfactory and/or they are very expensive. This paper presents a load based high speed weighting method for sorting the potatos. This method is based on the fact that the linear momentum of a potato is proportional to the mass of it. The usefulness of the method is demonstrated with sets of experiments.

醫藥品의 溶出에 關한 硏究 : Allantoin放出에 대한 軟膏基劑 및 添加劑의 影響 Effects of Ointment's Basics and Additives on the Release of Allantion

金在植,金壽億,徐成勳 慶熙大學校 1984 論文集 Vol.13 No.-

This experiment was conducted to investigate the release pattern of allantion from six kind of ointment bases. Release rate(K) of PEG ointment was 3.68 which was the most value in experimented ointment base, nest order was cold cream (K=1.42). In the case of additives, urea enhanced the release of allantion from six kind of ointment , PVP enhanced the release of allantoin from only Hydrophobic ointment bases. Addition of DMS retarded the release of allantion from six kind of ointments, the more concentration of DMS was increasing, the greater retarding effect became. But, in the case of PVP and urea, the greater concentration of additives became, the more release rate was increasing
