  • Diverging channel from gas burner exit to the inlet section of Heat Recovery Steam Generator (HRSG) has been re-designed for 1 MW system. To improve the uniformity in velocity and temperature distribution of existing design(Case A and B) of 300 kW HRSG system, two additional test geometries have been chosen for the numerical simulation. At first, gas burner exit section has been centered to the inlet section of boiler(Case C) and uniformity has been improved considerably. Secondly, the diverging channel length can be further reduced for compact geometry with new guide vane design (Case D and E). Proposed design shows overall improvement in uniformity in velocity and temperature distribution compared to existing one.

  • The marketing system of non-timber forest products has been criticized as it mainly depends upon private local dealers, having too many steps between producers and consumers, we believe, which makes it less efficient. Meanwhile, there were only a few empirical studies of how they are delivered to consumers. In order to devise and implement targeted forest policies efficiently, it is quite necessary to understand the distribution channel of them. We analyzed the distribution channel of chestnut, bitter persimmon, oak mushroom, and wild greens by data analysis, field and phone survey, and then drew an implication for improving the marketing system. First of all, the number of middle step has to be reduced and the direct transaction has to be expended. In addition, we need to have more active involvement of Forest cooperative in production sites, adding values by processing, and the upgrade of current marketing centers of non-timber forest products, which have been launched since 2004 by Korea Forest Service.

  • 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.

Especially, we study on the relative importance of each CS variables by distribution channel. Nowadays, most of manufacturing companies are proceeding the product servitization, which is combined service contents with product characteristics in the field of manufacturing industries. Methods: We surveyed humidifier purchaser about the some of CS variables and analyzed it using SPSS 21.0 and AMOS 21.0 as a statistical analysis tool. We use the frequency analysis, confirmatory factor analysis, multi-regression analysis and structural equation modeling analysis for our empirical study. Results: As the result of study, we find that Service Quality(SQ) influence Customer Satisfaction(CS) and CS influence Customer Loyalty(CL). Also, we verify that CS works mediate interaction on the effects between SQ and CL. And there are the significant relative effect of SQ to Customer Satisfaction in some of distribution channel. Conclusion: Finally, we make certain that the market size of the Humidifier goods industry will be increased rapidly. And the distribution channe l is more important to medium and small-sized enterprise. So, we have to pay attention to the study on the distribution channel of the Humidifier goods industry.

  • 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.

  • 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.
