The HANARO, a multi-purpose research reactor of 30 MWth open-tank-in-pool type, has been under normal operation since its initial criticality in February, 1995. Many experiments should be safely performed to activate the utilization of the HANARO. A flow simulated test facility has been developed for the verification of structural integrity of those experimental facilities prior to loading In the HANARO. This test facility is composed of three major parts; a half-core structure assembly, flow circulation system and support system. The half-core structure assembly is composed of plenum, grid plate, core channel with flow tubes, chimney and dummy pool. The flow channels are to be filled with flow orifices to simulate similar flow characteristics to the HANARO. This paper describes an analysis of the flow distribution of the cote channel and compares with the test results. As results, the analysis showed similar flow characteristics compared with those in the test results.

Marketing channels have been characterized as social systems by the recent channel literatures. Under this assumption, many channel behavioral theories were developed by examining hypothetical relationships among several channel variables. Among them, interrelationship of channel cooperation with other variables has been one of major concerns to channel managers. From this point of view, the objective of this paper is to examine the role of cooperation in the franchise system of garments goods. In order to achieve our goal, data was collected from garment retailers and a simple random sample of 150 dealers was drawn and tested. Major findings through the data analysis are as follows : 1. Higher levels of dependence lead to higher levels of cooperation. 2. Noncoercive sources of power tends to increase intrachannel cooperation. However, the hypothesis that higher levels of coercive sources of power will lead to lower levels of cooperation was not statistically supported. 3. Another hypothesis that higher levels of conflict will lead to lower levels of cooperation was partially supported. 4. Higher levels of cooperation lead to higher levels of cooperation. In this study, data was gathered from the retail side of the franchise channel dyad for garments goods. Therefore, future research are suggested to investigate respondents of both sides(franchiser and franchisee) of the channel dyad.

Characteristics of the flow and heat transfer in a channel of 37 rods are investigated numerically. The flow is taken to be a fully developed incompressible laminar flow and it has an uniform temperature profile at the inlet and flows down through the channel of constant wall temperature. A boundary-fitted coordinate system is used for the complex geometry. Calculation is initiated by calculating the developed flow profile and then proceeds to temperature development. Through the calculation the details of the flow and temperature distribution characteristics are found, and discussion is made on the mechanism of the transport phenomena in the complex geometry in terms of wall shear stress distribution, non-dimensionalized velocity, friction factor, Nusselt number distribution, Reynolds number, and porosity. Also the effects of the eccentricity in rod configuration are analyzed and its importance is emphasized.

RYUTSUKEIRETSUKA(Vertical Marketing System) developed by the Japanese Leading Manufacturers began to turn weak with the presence of the large- scaled retail enterprises since 1980’s. Therefore the alliances between major manufacturers & large distributors that were in the conflict relations for a long time began to progress. In accordance with this change in the distribution channel practice, the stance of the distribution channel theory in Japan had also changed. As the normative researcher group who had been critical to RYUTSUKEIRETSUKA and sympathetic to the task of merchant judged that it would disappear sooner or later, they considered positively the alliances between major manufacturers & large distributors which the latter were in dominant position. On the other hand, even the empirical researchers who supported the affirmative function of RYUTSUKEIRETSUKA changed their standpoint. They recognized the new channel practice, in other words the vertical alliances between the power companies, would be the frontier of research in accordance with the impetus of positivism in terms of the Marketing methodology. Thus, researchers of distribution channel theory in Japan who supported the normative approach become few and even changed to hurry to absorb in the empirical research, while moving the main focus of the research from RYUTSUKEIRETSUKA to the Alliances. In the long run, the distribution channel theory which was regarded as the leading principle of the Japanese Marketing has just made the methodological paradigm shift. The author suggests a critical viewpoint against the current Japan’s academism with the assumption that RYUTSUKEIRETSUKA has negative aspects.

The main purpose of this study is to identify and analyze the antecedent factors of internalization in channel system. Channel members opportunism and transaction atmosphere were identified as two major antecedent factors of internalization and some deteminants of those two factors were also analyzed. By using correlation, regression, and analysis of variance, eight research hypotheses were evaluated and all hypotheses except one were strongly supported and accepted. Some managerial implications were also discussed.

This paper presents the channel analysis considering power distribution network(PDN) system of PCB. For achieve the target PDN system we proposed the useful design approach for acquiring the characteristic target of power distribution network in overall frequency ranges. The proposed method is based on the hierarchical approach related to frequency ranges and the path-based equivalent circuit model to consider the interference of the current paths between the decoupling capacitors and the board through it is a lumped model for fast and easy calculation, experimental results show that the proposed model is almost as precise as the numerical analysis. The analysis of PDN system shows that although the effective inductance of package dominatly affects the power noise and the signal transfer through data channel, the board PDNs also can not be neglected for achieving the accurate channel signaling. Therefore, we must design concurrently the chip, package, and board from the initial spec design of high speed digital system.

Alluvial-plain deposits in the southeastern part of the Eumsung Basin (Cretaceous) are characterized by coarse-grained channel fills encased in purple siltstone beds. It represents distinct channel geometry, infill organization, and variations in facies distribution. The directions of paleocurrent, sedimentary facies changes, and channel-fill geometry can be used to reconstruct a channel network in the alluvial system developed along the southeastern margin of the basin. The channel-fill facies represent downstream changes: 1) down-sizing and well-sorting in clast and martix of channel fills and 2) internal organization of scour fill or gravel lag and overlying cross-stratified, planar-stratified beds. These findings suggest multiple stages of channel-filling processes according to flooding and subsequent stream flows. In the small-scale pull-apart Eumsung Basin (${\sim}7{\times}33km^2$ in area), vertical-stacked alluvial architecture of the coarse-grained channel fills encased in purple siltstone is expected to result from episodic channel shifting under a rapidly subsiding setting.

The ICT(information & communication technology) led to a dramatic change of floral distribution service, a phase of competition between wholesales and retail stores, and distribution channels in floral industry. It was expected that a role of the intermediaries in this industry would have reduced due to the improvement of transaction process by ICT. However, the ICT made to overcome a regional limit of the floral retail distribution service leading to an increase in sales and enlargement of the stores. And even it made possible to bring out another type of intermediaries such as private associations. This case study focuses on what kinds of efforts the floral wholesale distributors have made to enable a distribution process more smoothly between the wholesale distributors and retail stores through the information system, and what the failure factors in adopting the information system have been. This paper is also to examine how the wholesale distributors have changed themselves to gain dominant positions in distribution channels. As a result of the study, it was found that the intermediaries mostly failed in successfully achieving the distribution channel innovation through the information system because of several main reasons. FLOMARKET Inc. tried to innovate a distribution channel to obtain high quality goods through consolidating a wholesale distribution market in that segregated both floral joint market from free markets. after implementing the information system with consideration of the failure factors, FLOMARKET Inc. was able to minimize goods in stock and make a major purchase of various goods. In addition, it made a possible pre-ordering process and an exact calculation of purchasing goods so they could provide their products with market price in real time, which helped for the company to gain credits from their customers. Also, FLOMARKET Inc. established the information system which well suited to its business stage in order to deal with a rapidly changing distribution environment. It's so obvious that the transaction processing system of FLOMARKET Inc. definitely helped to share information among traders more seamlessly and smoothly in realtime, standardize goods, and make a transaction process clearer. Besides, the transaction information helped the wholesale distributors and retail stores to make more strategic decisions in their business because through the system they enabled to gather the marketing intelligence information more easily and convenient. If we understand that the floral distribution market is characterized by the low IT- based industry, it's worth to examine a case study proving that the information system actually increases the productivity of the transaction process in the floral industry.
