For the measurement of liquid level in ship's cargo tank, ballast tank, fuel oil tank and fresh water tank, several types of gauge meter are used such as tubular type, magnetic float type, reflex type transparent type and welding pad type. Among them, magnetic float type gauge meter is environmental friendly device because it is free of power source and maintenance. The main obstacle of the device is relatively large error bound. In this paper, finite element method is used to design and analysis of the magnetic float type gauge meter. The operation of reed switch according to the magnetic field has been successfully described and agreed well with experimental measurement. The optimum geometry with combination of permanent magnet and reed switches are designed to achieve 98 % accuracy of fluid level.

A sequence characterized amplified region (SCAR) marker, which was tightly linked with the A1 mating type locus in Phytophthora infestans, was developed. During the random amplified polymorphic DNA-based phylogenic studies of 33 isolates of P infestans collected from year 2002 to 2004, we found an A1 mating type-specific DNA fragment. This 573-bp DNA fragment was generated only in the genomic DNA of the A1 mating types, when OPC-5 primer was used. Based on the specific DNA sequence, we designed the primer sets for generating the A1 mating type-specific 569-bp DNA fragment. When 33 genomic DNAs of P. infestans were subjected to PCR amplification using different primer combinations, the A1 mating type-specific DNA was amplified, when LB-1F and LB-2R primers were used. The specific 569-bp DNA fragment was generated only from all 18 A1 strains, but not from 15 A2 mating type strains. These results corresponded to the mating type discriminating bioassay of 33 isolates of P. infestans. Therefore, the primer combination of LB-1F/LB2R was chosen as a SCAR marker. Overall, this study indicates that the SCAR marker could be developed into a useful tool for mating type determination of P. infestans.

Curve Numbers (CN) for the combination of land use and hydrologic soil group were regionalized at Imha Watershed using Long-term Hydrologic Impact Assessment (L-THIA) coupled with SCE-UA. The L-THIA was calibrated during 1991-2000 and validated during 2001-2007 using monthly observed direct runoff data. The Nash-Sutcliffe (NS) coefficients for calibration and validation were 0.91 and 0.93, respectively, and showed high model efficiency. Based on the criteria of model calibration, both calibration and validation represented 'very good' fit with observe data. The spatial distribution of direct surface runoff by L-THIA represented runoff from Thiessen pologen at Subi and Sukbo rain gage station much higher than other area due to the combination of poor hydrologic condition (hydrologic soil C and D group) and locality heavy rainfall. As a results of hydrologic condition and treatment for land use type based on calibrated CNs, forest is recommended to be hydrologically modelled dived into deciduous, coniferous, and mixed forest due to the hydrological difference. The CNs for forest and upland showed the poor hydrologic condition. The steep slope of forest and alpine agricultural field make high runoff rate which is the poor hydrologic condition because CN method can not consider field slope. L-THIA linded with SCE-UA could generated a regionalized CNs for land use type with minimized time and effort, and maximized model's accuracy.

The cyclic undecapeptide cyclosporin A (CyA), one of the most valuable immunosuppressive drugs, is produced nonribosomally by a multifunctional cyclosporin synthetase enzyme complex by the filamentous fungus Tolypocladium niveum. To increase CyA productivity by wild-type T. niveum (ATCC 34921), random mutagenesis was first performed using an antifungal agar-plug colony assay (APCA) selection approach. This generated a mutant strain producing more than 9-fold greater CyA than the wild-type strain. Additionally, a foreign bacterial gene, Vitreoscilla hemoglobin gene (VHb), was transformed via protoplast regeneration and its transcription was confirmed by RT-PCR in the UV-irradiated mutant cell. This led to an additional 33.5% increase of CyA production. Although most protoplast-regenerated T. niveum transformants tend to lose CyA productivity, the optimized combination of random mutagenesis and protoplast transformation described here should be an efficient strategy to generate a commercially valuable, yet metabolite low-producing, fungal species, such as CyA-producing T. niveum.

The importance of the community centers has been increased throughout the decade. With the interest on the centers, the quality of the architectural design of the centers have been much improved. But the importance of the interior design and color' design of the centers have been ignored. It is quite sure that the quality of the interior design impact on the satisfaction degree of the users. And color is the important element which can control the quality of the interior design economically. This study surveyed the three community centers in Seoul to investigate the status of the color usages. And to consider the user's need, and preference in color design, this study performs the questionnaire about the color image and color pallette preference of the users and interior design professionals. Mainly highly bright and low chromatic YR colors were used, giving rigid and monotonous atmosphere. The most preferred color image were warm, bright and secondly friendly, simple, soft, open. And the preference for pallette were various but we can find the difference of color preference and color combination type according to the user's group. As a result, This study proposes the basic guidelines for color design, such as ideal color Image and color and color combination type and color pallette. This proposals can be applied as a basic guideline for color design of the community centers.

It is not easy to find a good production schedule which can be used in practice. Therefore, production scheduling simulation with a simple dispatching rule or a set of dispatching rules is used. However, a simple dispatching rule may not create a robust schedule, for the same rule is blindly applied to all internal production processes. The presumption is that there might be a specific combination of appropriate rules that can improve the efficiency of a total production system for a certain type of orders. In order to acquire a better set of dispatching rules, simulation is used to examine the performance of various combinations of dispatching rule sets. There are innumerable combination of rule sets. Hence it takes too much computer simulation time to find a robust set of dispatching rule for a specific production system. Therefore, we propose a concept of the knowledge based simulation to circumvent the problem. The knowledge based simulation consists of knowledge bases, an inference engine and a simulator. The knowledge base is made of rule sets that is extracted from both simulation and human intuition obtained by the simulation studies. For a certain type of orders, the proposed system provides several sets of dispatching rules that are expected to generate better results. Then the scheduler tries to find the best by simulating all proposed set of rules with the simulator. The knowledge-based simulator armed with the acquired knowledge has produced improved solutions in terms of time and scheduling performance.

Purpose - This study aims to proposes a conceptual framework to segment multi-national products based on a Chinese consumer's perception of multi-national products, to find the role of consumer ethnocentrism (CET) in country of origin (COO) effects for Chinese, and to figure out how different dimension of CET Effects on purchase intention developed market and home country. Research design, data and methodology - This study selected a 2×2×2 factorial design for the hypothesis test based on the product category × combination of manufactured type × Ethnocentrism level. This study distinguishes products between luxury (Burberry) and non-luxury (Nike) products and choose combination of manufactured type (Spain vs India/ Spain vs China) in order to perform comparative studies. A total of 223 Chinese participated in the experiment. After being exposed to each scenario, participants were asked to respond to questions about brand preference and purchase intention Results - Regarding to luxury made in developed country, it is worth that exposing COO information to low level of ethnocentrism consumers. Regarding to non-luxury product made in emerging country, it makes it worse when COO information to high level of ethnocentrism consumers. Lastly, regarding to non-luxury product, patriotic consumers prefer to purchase product made in home country.

The analysis in this work is about costumes among the rhythmic gymnasts in competition, which is intended to develop designs about rhythmic gymnastics costume and provide the basic material from the results. In its research method and range, the general information on rhythmic gymnastics was reviewed in literature and the case analysis was followed about costumes of world high rankers in competition during 2012~2015 seasons. Research showed the following results. First, leotard took a shape of skirt-added one-piece type, where a combination with long tight sleeve, round neck line, and stand-up collar had a relatively higher percentage in design. With regard to a bottom line of skirt, an amorphous type was most common that highlights rhythmical beauty without any particular form. This design exposed shoulders and waists on both sides, expressing the feminine beauty. Second, in color used mainly, white appeared most frequently. In its combination, more than three were employed. Third, transparent mesh was applied as basic, where lace and chiffon were used. Abstract pattern took the highest portion in pattern. Particularly, crystal bead or gradation coloring was used to maximize the visually splendid image, giving an effect of optical illusion as if neckless clothing, choker, bracelet, or glove were worn. Fourth, it appeared that the costume for each event was changed in every season, when only music was substituted but the same earlier costume was put on for the different event.
