Fowl cholera(FC), which has been classified as reportable animal disease in Korea, occurred in the backyard farm located in Chungju, Chungbuk province. The farm was not ordinary domestic poultry farm but backyard farm with main cultivation of fruits. The farmer reported unusual mortality of chickens which were grazed in his own fruit farm without any poultry house. There was a lots of opportunities to contact with wild animals including wild birds freely. Clinical signs observed in the chickens were torticolis, mucous excretion from mouth and greenish diarrhea. On the necropsy we found multifocal necrosis on the surface of liver, hemorrhages in the epicardium and ovary and mucopurulent exudates in the joint. The causative agents was isolated from the liver of chickens collected from the farms and identified as Pasteurella multocida using biochemical tests of bacteria. Also, the isolated bacteria were inoculated into specific pathogen free chickens to evaluate the pathogenicity. High mortality and similar pathological lesions compared to those of chickens died in the farm were observed. We report the first case of fowl cholera of the chickens in Korea and further studies are needed to evaluate the serotype, genotype and pathogenicity of isolated Pasteurella multocida.

With the steady growth in the scale of the domestic traditional liquor industry, the interest in makgeolli has also been increasing. As the demand for makgeolli increases, interest in manufacturing differentiated makgeolli by adding additional raw materials such as fruits is increasing. In this study, makgeolli with low storage persimmon juice was manufactured, and the sweet taste of persimmon was imparted without adding sweeteners. Unsweetened, high-quality persimmon makgeolli with an alcohol content of 15% or more was manufactured and its quality characteristics were analyzed. Yeast was selected after producing fermented yeast by treating domestic isolated yeast and commercial yeast. Upon producing fermented yeast, persimmon makgeolli was manufactured by varying the amount of persimmon juice added to the fermented yeast. As a result of analyzing the quality characteristics of persimmon makgeolli, the pH was 4.02-4.25, the total acid (citric acid, %) was 0.30-0.43, the amino acidity (glycine, %) range was 0.05-0.15, and the alcohol content (%) was 15.64-18.48.(p<0.05). Reducing sugar (%) was 1.82-12.68 and total sugar (%) was 1.41-10.42, exhibiting a tendency to increase as the amount of reducing sugar and total sugar and the amount of juice added increased (p<0.05). Considering the sensory characteristics, a sample with 50% persimmon juice added showed a significantly higher residual sugar content, and the residual sugar content had a positive effect on the sensory characteristics. Therefore, 50% persimmon juice was added when making persimmon makgeolli. It is suitable for high-quality, non-sweetened persimmon makgeolli that preserves the taste of persimmon, which suits the consumers'taste.

This paper studies a series of capital market promotion policies Korea pursued over a 30-year period during its development era (1960s - 1980s). The purpose of this paper is twofold. The first purpose is to understand the policy approaches Korea took, and the second is to extract lessons that can benefit policymakers in the developing world, where capital market promotion is an important policy goal. There are two key features of Korea's capital market promotion policies. First, the government was actively involved, sometimes indirectly by giving tax incentives to encourage IPOs. However, in other times, it was directly involved by giving IPO orders and threatening those that did not comply. No stock exchange in a developed country has ever experienced such government involvement. Combined with rapid economic growth, this interventionist approached allowed the Korean stock market to experience phenomenal growth over a short period of time. Second, the capital market promotion policies had multiple objectives. One was to mobilize domestic capital for economic development. Another was to lower firms' debt-to-equity ratios. Most interestingly, however, the Korean government wanted to popularize stock ownership, thereby allowing ordinary Koreans to share in the fruits of economic growth.

The ESS is composed of Battery Package, PCS(Power Conditioning System) Package, BCU(BESS Control Unit). In Jeju smart grid test-bed, we have developed a business model by ESS power system, renewable energy, transportation, such as customers, and have demonstrated above things. We have analyzed the EMS(Energy Management System) model of KPX where manages supply and demand of domestic electrical power system. We modified and launched EMS for microgrid but the cost was expensive and the system was large size. For releasing this system from industry as a whole, it is imperative to develop PMS(Power Management System) for microgrid. However, the cost of EMS for microgrid is expensive, some systems because it is a large development of the all of the first fruits in urgent PMS(Power Management System) for microgrid to be used in industry in general. Therefore, in this paper, we propose the ESS model considering the power systems characteristics and extensibility in korea. and also we propose the PMS to manage the ESS systems.

There is a significant demand to make various dissolved gases in water. However, the conventional aeration method shows low gas mass transfer rate and gas utilization efficiency. In this study, a novel rotating wheel entraining gas method was developed for making high dissolved $O_2$ and $O_3$ in water. It produced higher concentration and higher transfer rate of dissolved $O_2$ and $O_3$ than conventional bubble aeration method, especially almost 100% of gas transfer efficiency was achieved for $O_3$ in enclosed reactor. For application of rotating wheel entraining gas method, aerobic bio-reactor and membrane bio-reactor (MBR) were successfully used for treatment of domestic and pharmaceutical wastewater, respectively; and vacuum ultraviolet $(VUV)/UV+O_3/O_2$ reactors were well used for sterilization in air/water, removal of dust particles and toxic gases in air, and degradation of pesticide residue and sterilization on fruits and vegetables.

The research results on the superconducting magnet for whole body MRI are presented. The magnet consists of main coil with 6 solenoid coils, shielding coil with 2 solenoid coils and 6 sets of cryogenic shim coil. The ferromagnetic shim assembly is installed on the inside wall of the room temperature bore for shimming inhomogeneous field components generated due to manufacturing tolerances, installation misalignments and external ferromagnetic materials near the magnet. Also, the magnet is enclosed with the horizontal type cryostat with 80cm room temperature bore to keep the magnet under the operating temperature. The magnetic field distributions within the imaging volume were measured by the NMR field mapping system. Through the test, the central field of magnet was 1.5 Tesla and the field homogeneity of 9.3 ppm has been obtained on 40cm DSV(the diameter of spherical volume) and using this magnet, comparatively good images for human body, fruits and water phantoms have been achieved.
