Neohesperidin dihydrochalcone(NHDC) is an intense sweetener with lingering aftertaste, which limits NHDC to use as a sweetener in food products. This study was conducted to examine the changes of teste quality of NHDC when using $\beta$-cyclodextrin($\beta$-CD) as a taste modifier. A series of $\beta$-CD(0.01%, 0.03%, 0.1%, 0.176%) was added to NHDC solution (100ppm) and the taste quality was evaluated by magnitude estimation. It was found that $\beta$-CD produced a significant effect in the reduction of aftertaste of NHDC(p<0.01) and sweetness as well.(p<0.001). Linear regression(log mean magnitude estimate versus $\beta$-CD concentration) analysis showed that the intensity of sweetness(n=-0.31) decreased more rapidly than that of aftertaste(m=-0.17). This result suggests the possibility that $\beta$-CD may form inclusion complex with NHDC, so that the hydrophobic portion is encapsulated in the cavity of $\beta$-CD and the carbohydrate moiety is oriented to the outside of the cavity. Or it may be that $\beta$-CD competes with the NHDC molecule for binding to the taste receptor, resulting in reduced perceived intensity.

The conservation treatments of 10-storied pagoda in the temple of Kyoungchunsa is progressed favorably to come to the finish since 1995. Most of all, the important conservation treatments are stone crack, exfoliation and partial form modification. This pagoda has been made up a complicated structure constructed using 142 stones. Therefore, the stone crack and exfoliation have been occurred as very varied forms. Especially, the stylobate of the pagoda has 19 substitution stones of 48 stones, which is40% of modern stone substitution. It is supposed that there is serious weathering on the stones. The other stones, which are no substitution stones, have some kinds of weathering and so we carried out inside replenishment and partial outside reconstruction of crack stones using high molecular resin and substitution stone. The stone of each storey has also partial difference, but the condition of serious weathering on the whole. We can detect general degree through treatment of high molecule resin or distribution research of contaminated material on 10-storied pagoda in the temple of Kyoungchunsa. Especially, we are able to analyze general weathering degree and know details weathering of each storey or direction for the difference of replenishment quantity and different pattern of stone crack degree. Also, the distribution research will accomplish very important parts of examining environment effects and use as research data of cultural heritage conservation field.

The rapid growth in communication technology has led to the development of effective ways of sharing ideas and information in the form of speech and images. Understanding this information has become an important research issue and drawn the attention of many researchers. Text in a digital image contains much important information regarding the scene. Detecting and extracting this text is a difficult task and has many challenging issues. The main challenges in extracting text from natural scene images are the variation in the font size, alignment of text, font colors, illumination changes, and reflections in the images. In this paper, we propose a connected component based method to automatically detect the text region in natural images. Since text regions in mages contain mostly repetitions of vertical strokes, we try to find a pattern of closely packed vertical edges. Once the group of edges is found, the neighboring vertical edges are connected to each other. Connected regions whose geometric features lie outside of the valid specifications are considered as outliers and eliminated. The proposed method is more effective than the existing methods for slanted or curved characters. The experimental results are given for the validation of our approach.

A stack must be designed to 1) reduce or eliminate rainfall or snowfall into a industrial exhaust system, 2) minimize a resistance to flow, 3) maximize the vertical dispersion of the contaminated air and 4) minimize maintenance. The weather cone stacks and the elbow-type stacks are very popular in Korea. But they add some resistance to the exhaust system resulting in reduction of air flow rate, but also deflect the noxious contaminants downward in undiluted form. To solve these problems, ACGIH (American Conference of Governmental Industrial Hygienists) suggested the vertical discharge stack with concentric space between the upper stack with larger diameter and the lower stack with smaller diameter. The preliminary test showed that the vertical discharge stacks did not have the good rainfall protection. The reversed cone were newly devised to satisfy the requirements for the good stack. Subsequently, the amount of rain being penetrated through the stacks was measured while the stacks were simultaneously and naturally exposed to rain in the same area outside. Test results indicate that none of the stacks tested completely exclude rain. The efficiency of rainfall protection and the pressure loss coefficient were compared. The temporary conclusion was reached to the point that the reversed cone stack is the best one. Further research is underway.

The exhibition space is a concept that is used to extract only the function of exhibition in an art museum combined with various cultural facilities. It mediates works, audience, and space. Therefore, it is considered that the exhibition space will not only judge the space by the form of the building, but also the true meaning will appear when the exhibition, the space and the environment coexist. His exhibition space has a story from the outside to the inside and the exhibition. In this study, we try to understand the characteristics of his space by analyzing the way of organizing exhibition and exhibition in his exhibition space. As a result of analyzing the cases suggested on this thesis through this point of view, Ando Tadao represented characteristics of his own exhibition space by harmonizing the demand of each exhibition space with his architecture language. His exhibition space provides the experiential space in the harmony of the nature and artificiality as inpouring the nature into the complex traffic line. And, the exhibition is constituted as a result of fully considering the overall situation of the space environment. He tries uniting the space and art by interpreting the work in the space rather than arranging the works. Consequently, It gives visitors the direct space experience through the intentional traffic line and is becoming an exhibition space that can express the exhibition only in that space as constituting it differently in accordance with the character of work.

Arbitration, a form of alternative dispute resolution (ADR), is a technique for the resolution of disputes outside the courts. Parties often seek to resolve disputes through arbitration because of a number of perceived potential advantages over judicial proceedings: Arbitration is generally faster and more inexpensive (cheaper) than litigation in court. The Republic of Korea enacted the "Arbitration Industry Promotion Act" to develop arbitration. This law provides for the establishment and operation of arbitration institutions, training of arbitration experts, and support of arbitration studies and international exchanges. Effective operation of an arbitration institution has an important influence on the development of arbitration. Neutral and good arbitration experts improve the authority of arbitration. The academic study of arbitration theoretically develops the arbitration procedure. In addition, this paper referred to some additional factors that South Korea should have in order to become an attractive place of arbitration. Neutrality and fairness of the court of arbitration are highly important factors in arbitration. Therefore, the arbitration institution should be operated independently and clearly from the government to ensure neutrality and fairness. The parties of arbitration should also be free and able to defend their interests sufficiently in the arbitration proceedings. Lastly, coordination between this law and other laws is necessary.

A electromagnetic waves are used for sensing in insulation diagnosis at electric machine or equipment. When it a method, waves are transformed into the FFT(Fast Fourier Transform); a kind of the process for data transformation. In a general way, a scientist use frequncy band 30[㎒]～l[㎓] to applied field. If we are measured high frequency band, we will need to a high capacity hardware. Also a antenna has a fault on atmospheric phenomena, outside environment and the like. In this paper We proposed new method for detecting electric equipment faulty state using only electric voltage which is generally measured in the electric and electronic field. It is called the Partition-FFT The analytic method is this first divide measured voltage waves into equal parts, second each deal with give effect to the FFT, finally each results deal with a graphic method and gather graphic. We are compare Partition-FFT with discharge form by tracking tester. As the result it demonstrated that the Partition-FFT is applicable.

This study is to analyze the building layout of traditional government office building in Chungchong province with Chungchong-do regional maps and Eupjis(邑誌) being compiled in the late Chosun dynasty. The building layout of government office in Chungchong-do is followed in the wake of the spatial structure, Sam-Jo(三朝, three reign) and Oejeon-Naejeon(外殿-內殿), of Chosun dynasty palace. The planning principle of Sam-Jo at government office, Dongheon(東軒) territory for rule administration corresponds to Chijo(治朝) with a local governor who is the ruler, as for the Naea(內衙) territory which a family of him and he lives in, it is corresponded to Yeonjo(燕朝), and in the job space of Ajeon(衙前), it is corresponded to Oejo(外朝). As for the application of the inside and outside principle of provincial government office, Dongheon is corresponded to Oejeon and Naea to Naejeon. A compositive and an approach axis of government office in Chungchong-do is correspond with Dongheon in the center, and these axes form an central axis and an entry space of government office included Oesammun(外三門) Naesammun(內三門) Dongheon or Naea. Because an essential performance of provincial government office is provincial administration, the layout configuration of government office is a function, which is an expression of an official institution.

Experimental data on the heat transfer characteristics of HCFC-123 and CFC-11 during condensation in horizontal smooth tube are presented. The experimental apparatus consisted of a closed working fluid loop, coolant loop, and measuring system. The major components of the working fluid loop made of a refrigerant pump, boiler, superheater, refrigerant flow meter, receiver and test section. The tube-in-tube type test section was made of smooth tube which were constructed form 9.52 mm outer diameter of smooth copper tube with 50 mm outside diameter of PVC tube duct. The ranges of parameter, such as refrigerant mass velocity, coolant flow rate, and quality were 90-325kg/($m^2$.s), 60-360kg/h, 5-95% respectively. Data were obtained under steady state condition for annular flow. As a result of these, the condensation heat transfer coefficients for HCFC-123 were slightly lower than those of CFC-11 from 8% to 15% inside horizontal smooth tube. Furthermore, a new generalized correlation for the heat transfer coefficients of HCFC-123 and CFC-11 during condensation inside horizontal smooth tube is proposed.
