The widespread use of self-service concepts in retailing has resulted in increased attention to the design of retail environments and to stimuli operating at the point of sale. One such merchandising technique, the "bundled presentation", i.e., related products are presented in close proximity to each other, is widely used by retailers but has rarely been investigated by academic consumer researchers. This study presents the results of a field experiment into the effects of presenting products in their usage context. Customers' attitudes towards the same product displayed in different ways are compared with each other. The results show that related products, i.e., products that are used together, should be presented in a coordinated display. Furthermore, the bundled presentation enhanced consumers' attitudes of the product when they saw it first in a bundled presentation and then evaluated it in front of a traditional presentation.

This paper is to review the conclusions of the Athens conference that has so far contributed to the conservation world. It is normally called the conclusions of the Athens conference as the Athens charter. But the conclusions of the Athens are not as same as the Athens Charter regarding the contents. The former had more valuable contents than the latter regarding historic monuments. And the report of the Athens conference including 56 articles and 500 pages with 55 photos was published in 1933 by the International Museums Office. But little attention has been given to the report of the Athens conference. Therefore the point I want to make is to review to the report in order to understand the agenda of the conference and to examine the Anastylosis in Acropolis. In conclusion, these agendas and the articles in the report show us that the conference was sort of milestone with some advanced modern philosophical and technical concepts about conservation and restoration of historic monuments. Also when the term of anastylosis turns to reconstruction in archaeological sites, we are going to face with the problems of authenticity.

Hexafluoropropyleneoxide ($C_3F_6O$, HFPO) is highly expensive and it may be used as a raw material for the synthesis of various fluorine based compounds. Currently, extractive distillation method has gained considerable attention to collect the HFPO from a mixture of HFPO / hexafluoropropylene ($C_3F_6$, HFP). Optimized operating conditions are studied using a theoretical method for the extraction process. Among available solvents for the purification process, the use of 1,1-dichloro-1-fluoroethane exhibits a high purity of HFPO as a top product and minimize the required heat duty. Since the boiling point of the solvent increases as the pressure in the column increases, the enhanced extractive capability of the solvent led to the high purity of HFPO at the high pressure.

Recently, the attention is paid to the problem of thermal crack by hydration heat according to the increase of high strength and mass concrete structures. At this point, various research has been carried out for the control of hydration heat in high strength and mass concrete. As a part of the research, the application of Low Heat Technology (LHT) for the control of thermal crack by hydration heat was investigated in this study. To investigate the application, it was selected LHT which can reduce hydration heat of concrete with effect in series I and II. Also, it was investigated the characteristics of hydration heat generation of low heat concrete using LHT with binder types in seriesIII.

Recently, STI process is getting attention as a necessary technology for making high density of semiconductor by devices isolation method. However, it does have various problems caused by CMP process, such as torn oxide defects, nitride residues on oxide, damages of si active region, contaminations due to post-CMP cleaning, difficulty of accurate end point detection in CMP process, etc. In this work, the various defects induced by CMP process was introduced and the above mentioned Problems of CMP process was examined in detail. Finally, the guideline of future CMP process was presented to reduce the effects of these defects.

Recently, the environmental problem has received considerable attention. so, many lamps have been developing for environmental requirement and energy efficiency. also, at glow discharge lamp researchers try to reduce energy spending that is power saving lamp. this kind requirement agree with strong points of electrodeless fluorescent lamp has received to now lighting sauce. At low pressure as mTorr I.C.P make high density plasma easily, is good to maintain discharge, has high ionization and does not have failing lighting and losing ability of electron radiation by oxidation and volatilization of electrodes, because this tape does not have electrodes. This point of I.C.P can use at electrodeless fluorescent lamp in this study ICP display elements and Ar, Ne, Kr are researched for optical characteristic. each gas is looked into optical characteristic, also mixed gases is experiment for optical characteristic.

Thermoelectric conversion efficiency of thermoelectric elements can be increased by using a structure combining n-type and p-type semiconductors. From the above point of view, attention was directed at ZnO as a candidate n-type semiconductor material and investigations were made. As the result, a dimensionless figure of merit ZT close to 0.28 (1073K) was obtained for specimens produced by the PCS (Pulse Current Sintering) method with addition of specified quantities of $TiO_2$, CoO, and $Al_2O_3$ to ZnO. It was found that the interstitial $TiO_2$ in the ZnO restrains the grain growth and CoO acts onto the bond between grains. The influence of the inclusion of $TiO_2$ and CoO onto the sintering behavior also was investigated.

Recently, LPG has been considered as more environmental friendly fuel than liquid fuels for vehicles. However because LPLi engine has the strong point that not only increases the volumetric efficiency and cold startability, but also decreases unburned hydrocarbon exhaust emission in warm-up condition, much attention has moved to development of the Liquid Phase LPG injection (LPLi) system from the mixer type LPG engine. To reduce exhaust NOx, this study investigated the effect of EGR with LPLi engine and determined optimized EGR feeding position and distribution. In addition, engine stability, performance, and exhaust emission level were evaluated.

This study starts from the question about the possibility of landscape, especially the possibility to give a new vision in the aspect of publicity. Such a concept of landscape architecture made its appearance in the last decade of the 20th century, as the flexible network to include the changes and the specificity of the surroundings, which simultaneously focuses on the temporality-the uncertainty. Moreover landscape architecture can be defined as the architecture in which the interest on human activities lie in the center of the concept. By analyzing concrete examples, the landscape architecture can be defined in 3 aspects : unity of building and nature, void and public space, space of expansion. As a result of the analysis of landscape architects' statements, it can be said that the issues of publicity are always put at the starting point of landscape architecture with its attention to the way to associate an individual with the others.

In this prolonged economic recession, the countries in Northeast Asia play a crucial role in the global market and the relationship between Korea and China gets more attention due to its significant achievement during the past 20 years after the establishment of diplomatic ties in 1992. In this regards, this study presents general overview of Korea-China Car Ferry Route and evaluates the efficiency level of each operating route using DEA model. Incheon-Yingkou, Incheon-Lianyungang, Pyeong Taek-Lianyungang are analyzed as efficent routes, while from the view point of passenger efficiency, 4 routes i.e, Incheon-Dalian, Incheon-Dandong, Pyeong Taek- Weihai, Gunsan-Shidao are also noted as efficient routes. Consequently, other inefficient routes can benchmark these efficient routes by increasing cargo volume and passengers.
