  • The two main purposes of this paper are to 1) investigate critical components of university information systems for information resources management, 2) develop a comprehensive framework model of university information systems for e-Business Era. Through a literature review and by employing group decision making techniques with managers of K University, critical components for developing university information systems were identified. The critical components of university information systems are 1) academic affaires. 2) general administration. (3) research administration. (4) information services. (5) management support, (6) cyber education. (7) knowledge management, (8) e-library. (9) mobile service. and (10) IT infrastructures. In the second stage. by employing IT experts in K University and other institutes. a comprehensive framework of university information systems for e-Business era was developed. The comprehensive framework shows that major components for university information resources management are (1) information infrastructure. (2) common operating environments. (3) applications/information services. The results of this study expect to help managers. who are in charge of university information systems. plan to develop information systems based on the framework proposed in this paper.

Comparison of two diagnostic methods, allele-specific real-time PCR and 3'-tailed PCR to discriminate between Salmonella enterica serovars Gallinarum and S Pullorum (Salmonella enterica serovars Gallinarum과 S Pullorum의 감별을 위한 2가지 진단법: allele-specific real-time PCR과 3'-tailed PCR의 비교)

  • Salmonella enterica serovars Gallinarum(SG, causative agent of fowl typhoid) and S Pullorum(SP, causative agent of pullorum disease) are very important bacterial pathogens in poultry industry. They share some common antigenic properties though the characteristics of outbreaks are quite different. To discriminate between SG and SP, we developed two rapid diagnostic methods, allele-specific real-time PCR and 3'-tailed PCR over 2 single nucleotide polymorphisms ($237^{th}\;and\;598^{th}$). In both methods, $237^{th}$ allele was found to be a good target for differential diagnosis, while $598^{th}$ allele produced some non-specific reactions.

  • Natural organic matter (NOM) is among the most common pollutant in underground and surface waters. It comprises of humic substances which contains anionic macromolecules such as aliphatic and aromatic compounds of a wide range of molecular weights along with carboxylic, phenolic functional groups. Although the concentration of NOM in potable water usually lies in the range of 1-10 ppm. Conventional treatment technologies are facing challenge in removing NOM effectively. The main issues are concentrated to low efficiency, membrane fouling, and harmful by-product formation. Ion-exchangers can be considered as an efficient and economic pretreatment technology for the removal of NOM. It not only consumes less time for pretreatment but also resist formation of trihalomethanes (THMs), an unwanted harmful by-product. This article provides a comprehensive review of ion exchange processes for the removal of NOM.

  • Molluscs from the Neolithic shell middens (Sugari, Pudjeong, Tongsamdong, Sangnodaedo, Sandeung, Yondaedo, Songdo and Kupyongri) in the southern coast, Korea, consisted of marine, fresh-water and land molluscs. Among these, intertidal species were exploited most abundantly as food resources, indicating a high dependence of intertidal shellfish collection activities. Especially oysters were the most abundant in these sites except Tongsamdong where mussels were predominant, indicating oysters were the most important food resources. Land snails from the sites consisted of woodland and open land species. Woodland species were more abundant than openland species, suggesting that there was a woodland environmint around the sites. Marine and land mollusc species from the sites are common in these rigions today, indicating no large-scale emvironmental changes have occurred since these middens formation period.

  • Gymnopus is a cosmopolitan genus of agaric fungi and consists of ~300 species. In Korea, Gymnopus represents common saprobic mushrooms, and 12 species have been reported in Korea. Several Gymnopus specimens were collected in Korea between 2008 and 2015. To identify them exactly, phylogenetic analysis was performed by means of the internal transcribed spacer region of ribosomal-DNA sequences from the collected Gymnopus specimens. Among them, G. iocephalus, G. polygrammus, and G. subnudus have not been reported in Korea. A phylogenetic tree and images are provided.

  • This physically-based hydrologic model is developed to calculate the soil-moisture balance on paddy fields. This model consists of three modules; the first is the unsaturated module, the second is the rice evapotranspiration module with SPAC(soil-plant-atmospheric-continuum), and the third is the groundwater and open channel flows based upon the interrehtionship module. The model simulates the hydrlogical processes of infiltration, soil water storage, deep perocolation or echarge to the shallow water table, transpiration and evaporation from the soil surface and also the interrelationship of the groundwater and river flow exchange. To verify the applicability of the developed model, it was applied to the Kimjae Plains, located in the center of the Dongjin river basin in Korea, during the most serious drought season of 1994. The result shows that the estimated water net requirement was 757mm and the water deficit was about 5.9% in this area in 1994. This model can easily evaluate the irrigated water quantity and visualize the common crop demands and soil moisture conditions.

  • Shepherd's purse (Capsella bursa-pastoris) is one of the minor but important vegetable in Korea. The present study records 4 fungal diseases of this plant occurring under natural condition for the first time in Korea. They are white rust caused by Albugo candida, downy mildew by Peronospora parasitica, leaf spot by Pseudocercosporella capsellae, and powdery mildew by Erysiphe cichoracearum of these, white rust and downy mildew were most common causing severe damages and should be managed for the development of greenhouse cultivation of this plant.

  • Species and anatomical characteristics of twenty-seven straw shoes (around AD 500s-600s) of Baekje Kingdom, excavated at Gwanbukri and Goongnamji relics of Baeje Kingdom, were examined. The shoe tissues were macerated and examined under microscope. They were identified as Typha spp (cattails), not any of straws such as rice. Cattails, a perennial glass, grow in low and swamp places. Cattails are not known as one of major raw materials for straw shoes. The cattail fibers are not as strong as those of rice straws, common raw materials for ancient shows.

  • This study discussed the international reorganization of fisheries in the East China Sea and the Yellow Sea, for the cases of Korea, China and Japan, through the fishery competition and the division of sea areas and resources. In these sea areas, each country has done mutual operation, which causes the fishery competition and controls fishery development. Besides, Exclusive Economic Zon(EEZ) established in 1996 resulted in the prominent changes of fishery development as well as fishery relationship among each country, demands reorganization of fisheries. New fishery order in these sea areas is controlled by BEZ system. The fishery reorganization according to EEZ is a common issue of each country and it also includes the importance of mutual fishery agreement. Resources of fisheries could be used continuously under reasonable management. Each country should consider the stability and existence of fisheries in the international viewpoint. At this point of time, those should be considered such as adjustment of interests according to the division of sea areas, establishment of resource management system and insurance of fishery management, for the subject of fishery reorganization.
