This research is focused on developing a methodology for detecting the time of model change in the pocess and on designing a procedure for identifying the change based on neuro-modeling. The proposed detection procedure uses a fixed series of one-step prediction errors, which are obtained from a pre-determined neural network model. The model identification procedure is based on neuro-modeling. Kohonen's Self-Organizing Map (SOM) neural network and Radial Basis Function (RBF) neural network are used for modeling of a dynamic manufacturing process which is considered as a quasi-stationary time series. The proposed SOM and RBF neural networks attempt to decompose a picewise stationary series into a set of stationary segments and predict each sub-series thereby. Three different approaches are compared for model identification: the first approach is based on the feedforward network with the back-propagation error rule; the second one is based on the Bayesian discriminant function for minimizing the average probability of error; and the third one is based on the minimum distance measure for mininuzing the Euclidean distance between the input feature vector and feature vectors of the each sub-models. The proposed approaches are verified throught simulations. The performance of the proposed approaches are efficient and the suggested methods can readily employed for real manufacturing applications.

명품에 대한 사회학적 해석 : An analysis of consumption of luxuries

최항섭 서울대학교 사회과학연구원 2003 한국사회과학 Vol.25 No.1-2

본 연구는 한국사회에서의 과시적 문화를 설명하기 위해서 명품소비를 분석하였다. 명품은 그 교환가치에 있어서나 상징가치에 있어서나 사치스럽고 고급스럽다고 사회의 일반적 인정을 받은 재화를 말한다 이러한 명품은 과거에는 주로 상류층만이 구매하는 것으로 인식되었으나 현재 비상류층 역시 명품구매에 적극적으로 나서고 있다. 명품은 상류층이 비상류층과의 구분을 위해서 사용되는 것이 일반적이지만 비상류층 역시 상류층을 모방하기 위해서 사용하고 있기도 하다 명품이 인기가 있는 이유로는 먼저 상징적 가치가 높은 재화에 대한 소유욕구의 재생산을 들 수 있으며, 비상류층이 명품구매에 뛰어들고 있는 현상은 '일치'의 욕구라고도 볼 수 있는데, 즉 ‘남들처럼’ 소비하는 행위를 말한다 과시의 욕구는 명품구매의 대표적 원인이며, 이외에도 명품자체의 미에 만해서 사는 것도 가능하며, 자신의 가치와 명품의 가치를 일치시키려는 욕구, 손에 닿을 수 없으리라 생각했던 것를 넣었을 때의 성취 감, 고급스러움을 유포하는 한국의 미디어, 베버적 의미의 사회적 폐쇄를 위한 상류층간의 연결망 형성과 유지의 필요성등이 현재 명품의 인기의 원인으로 제시될 수 있다 이러한 명품의 인기에 대해서는 긍정적 인식과 부정적 인식이 공존한다. 긍정적 인식은 좋은 것에 대한 자연스러운 욕구라는 데 기초하며, 부정적 인식은 프로테스탄트적 비판이 주류이다. 또한 비상류층의 명품구매에 대해서는 강한 비판들이 많이 나왔는데, 분수를 모르는 행위라고 비난하였으며 이는 한국사회에서 아직 강한 집단적 동질성이 그 집단의 성원에게 요구되고 있음을 간접적으로 보여준다 This paper concentrates on the consumption of luxuries in South Korea, which is one of the aspects of conspicuous culture in Korean society. We have to note that it is not only the high class but also the middle class, and even the low class who purchase the luxuries. While one buy luxuries to distinguish himself, others buy luxuries to imitate the high class. I also examined that traditional aspect of confarmity in Korean society is one of the key words to explain the explosion of desire for luxuries. People buy luxuries since their neighborhood buy them. Luxuries are often used as an element to link people, expecially high class as they possess symbolic value. There exist positive perspective and negative perspective on purchasing act of luxuries. Although some people regard it as natural and reasonable, others critic it based on protestant ethic. In particular, purchasing act of luxuries by the low class is severely criticized.

동학농민군의 대외 인식 : 대일관·대청관을 중심으로

배항섭 한림대학교 태동고전연구소 2004 泰東古典硏究 Vol.20 No.-

개항 이후 민중의 대일관과 대청관은 개항 이후 전개된 대일, 대청 관계 뿐만 아니라 임진왜란이나 병자호란과 관련하여 전승되어온 기억과도 관련이 있었다. l9세기 후반 대외적 위기의식에 매개되어 임진왜란을 비롯한 역사적 경험과 결합된 대일 적대감을 이미 강하게 가지고 있었다. 이러한 적대감은 개항 이후 일본의 침략 행위가 이어지면서 더욱 강화되었다. 특히 갑신정변 이후에는 일본과 연결된 개화당과 개화에 대한 적대감으로까지 연결되었다. 반면에 반청의식은 상대적으로 약화되었다. 이 점은 동학농민전쟁에서 극명하게 드러났다. 동학농민군은 斥倭·斥洋을 주장하였지만, 청에 대한 반대구호는 제기하지 않았다. 뿐만 아니라 농민군은 청의 침략성적 의도를 의심하지 않았고, 그들을 일본을 물리치는 연합세력으로 이해하였다. 이는 일본의 침략행위와 반일의식의 강화에 따른 반사효과라는 측면이 강하였다, 거란 임오군란 이후 청의 대조선정책과 그에 기반한 정치적 경제적 횡포와 침탈 등으로 미루어 볼 때 농민군의 대외인식이 불구적이었음을 보여준다. 그러나 동학농민전쟁과 청일전쟁의 전개과정에서 조선민중들은 청나라와 일본 군대의 행동양태 등을 통해 청과 일본을 구체적으로 직접적으로 경험할 수 있었다. 이러한 경험을 통해 민중들은 화이론적 세계관의 연장선에 있는 사대주의적 친청의식과 문화적 우월주의에 입각한 대일 적대감의 구각을 탈피해가가기 시작했다. From the beginnings of Korea's opening to the West, Korean people's view of Japan and that of Qing(淸) had been influenced by the relations with these two big powers at that time, and by the inherited memories about Japanese invasion of 1592 and Manchurian invasion of 1636. On the point of later nineteen century, when Korean people felt they were trespassed by neighboring powers, their anxiety soon shifted to hostility to Japanese due to their historical experience of Japanese invasion of 1592. This hostility to Japanese had been intensified by the Japan's continual invasive actions, and the Coup d'e-tat of 1884 by Progressive Party supported by Japan made this feeling firm, and it soon moved to the hostility to the Progressive Party and enlightenment itself. On the other hand, anti-Manchurian feelings were not comparatively hostile. Donghak Peasant Uprising is a good example. Donghak Peasant Army raised its voice up against the Japanese and westerners, but it was not so opposed to Qing. And the more, Peasant Army never suspected Manchurians' invasive intention, and even looked up them as an allied power to restrain Japanese power. Japanese invasive action and much more fixed anti-Japanese feelings had made Peasant Army prefer Manchurian force to Japanese one. But as a matter of fact, Manchurian force was only another threatening factor to Korea, and not less than Japanese one. This misjudgment showed that Peasant Army's understanding of international situation was prejudiced and distorted. But in the process of Donghak Peasant Uprising and Sino-Japanese war(1894), Korean people themselves had gone through hardships caused by two forces' military actions in the flesh. and this experience made Korean people break from the conventional attitudes, toadish pro-Manchurian mentalities based on sino-centralism and deep-rooted anti-Japanese feelings based on cultural chauvinism.

Cu(001) 표면에 성장시킨 Ni 초박막의 구조 연구

閔恒基,李圭燮 弘益大學校 科學技術硏究所 1995 科學技術硏究論文集 Vol.6 No.-

The growth of Ni deposited on Cu(001) surface at room temperature was studied by LEED(Low Energy Electron Diffraction) I/V analyses. For the Ni thin films of thickness from 1 ML(mono layer), the subsurface Ni layer below 1 ML Cu surface layer is found to be the optimum structure. This result is also consistent with the growth mode predicted by the first principles total energy calculation.

Agar-Gel Immunodiffusion Test를 이용한 돼지흉막폐염(Swine Pleuropneumoniae)의 진단에 관한 연구

심항섭,장경수,조용성,전무형 충남대학교 수의과대학 동물의과학연구소 1994 動物醫科學硏究誌 Vol.2 No.-

To establish an effective diagnostic measure for detection of the antibodies against Actinobacillus pleuropneumoniae, that is the primary agent of swine pleuropneumoniae, the methods for micro-agglutination test(MAT) and agar-gel immunodiffusion test(AGID) were improved and standarized and the comparative studies were carried out. The results obtained through the experiments were summarized as follows. 1. The rabbit hyperimmune sera to reference serotypes 1 to 6 were cross-tested with MAT and AGID. The range of antibody titers on MAT was 80 to 1280, showing the cross-reaction in serotypes 3, 4, 5 and 6. In AGID, the range of antigen titers was 8 to 32, and cross-reaction was observed in serotype 5. The optimal concentration of antigen MAT were 1.25㎎/㎖ 2. In AGID, the most promising antigen and the buffer for agar-gel were EDTA-treated antigen and 0.05M tris buffer(pH 7.2), respectively. 3. By the tests for 200 swine sera, it was found that the accumulative frequency of positive reaction for the 6 serotypes were 240 in MAT and 163 in AGID. 4. when compared the results of AGID with those of MAT for 200 swine sera, all sera with MAT titier under 20 were negative in AGID. Of the sera with MAT titer 40 and 80, 24.7% and 93.9% were positive in AGID, respectively. All sera with MAT titer over 160 showed positive in AGID. 5. In conclusion, the established MAT showed high sensitivity but low specificity, whereas AGID revealed low sensitivity but high specificity. The established AGID test was considered very efficient for detection of antibodies and serotyping of swine sera.

The results were summarized as follows: 1. Silkland growth was showed that resecting abdominal 2nd ganglion was more effective than those of abdominal 4th and 6th ganglia. 2. The shape of silkland was appeared as serpentining by resecting ganglia. 3. Spinning quantity was revealed that resecting abdominal 2nd ganglion was less than those of abdominal 4th and 6th ganglia. 4. Silkland growth and spinning quantity were revealed the same tendency in degree of increase. 5. Fibroin Component ratio of brave was seemed that abdominal 6th ganglion was moe effective than abdominal 2nd and 4th ganglia. 6. In the case of resecting ganglia, flimsy cocoon was formed at upper parts of cocoon and half of pupa body was mostly observed staying outside of cocoon in the cocoon shape at lower part of abdominal 4th ganglia. 7. Abdominal 2nd, 4th and 6th ganglia were expected to have a close connection with pupation and changing the pupa coloration. 8. Furction of evacuation was seemed to be controlled by abdominal 6th ganglia.

An Empirical Analysis of Smart Signage and Its Market Delimitation

( Hang Sub Kim ),( Bong Gyou Lee ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.8

This study demonstrates that ease of use, usefulness, and hedonic desires affect the intention to use smart signage, based on market delimitations. Smart signage is at an early phase of adoption and its market can be divided broadly into indoor and outdoor markets. In this study, an empirical study model was established in conjunction with the technology acceptance model (TAM), which was applied to the IT area of a smart signage map and to a hedonic model. Empirical results showed that the key hedonic attributes affecting the intention to use smart signage include information delivery for the indoor environment and emotional and entertainment content for the outdoor environment. In the future, specific guidelines can be presented to boost the usage of smart signage through an empirical study based on the identification of external factors that affect usage intention.

Monocrotophos poisoning in wild mallards(Anas platyrhynchos)

( Hang Sub Shim ),( Hae Sung Kim ),( Jong Tae Woo ),( In Seop Kim ),( Hae Sun Jung ),( Eun Ah Song ),( Jun Jo Bark ) 한국가축위생학회 2007 韓國家畜衛生學會誌 Vol.30 No.4

The toxicity of organophosphate arises from disruption of the nervous system due to the inhibition of cholinesterase enzymes, leading to death. Six dead mallards were found at Ansung where is one of the most popular wintering sites for migratory birds in Korea, and requested for diagnosis to Gyeonggi Veterinary Service on January of 2007. Some examinations including polymerase chain reaction(PCR) could not find any evidence of specific disease condition. However, the contents of gastrointestinal tracts of the birds contained residues of monocrotophos ranged from 31.3ppm to 294.3ppm by gas chromato-graphy and mass spectrometry. It can be supposed that monocroptophos was responsible for the death of mallards by this results,
