  • During the 2000s there were changes in the educational facility policy having impact on school architecture, such as departmental classroom system by the 7th national curriculum and BTL projects. Especially for secondary school architecture with the new keyword of 'departmental classroom system' unlike elementary school with the well-known keyword of 'open classroom', the emergence of new school architecture was anticipated. For these reasons it is worth while to notice secondary school architecture in the 2000s and this study aims to review the architectural characteristics of middle schools as first step. Cases of 18 schools selected by EDUMAC were analyzed focused on site planning and planning characteristics of each spaces. Through the analysis, the architectural characteristics of middle schools in the 2000s are summarized and comments on some problems are made. In summary, case schools have typical characteristics of Korean school architecture in unit classrooms and block plan for daylight condition. On the other hand, they have more diversity in space organization and facility program. But it leave something to be desired in expressing urban architectural characteristics, traditionality and locality with searching for new school architecture.

  • In order to produce a new antibiotic material against Jurkat T cells using horizontal gene transfer among microbes, co-cultures between soil bacteria AY2000 and the multiple antibiotic producer S. griseus was carried out. It showed that the highest active substance against Jurkat T cells was produced at 48 hr of co-culture time with MTT assay. Moreover, a morphological change of nuclear of Jurkat T cells treated with co-cultured substance was observed in DAPI staining. This result suggests that a new material was produced with co-culture supernatant, and that co-culture between microboes can develop new antibiotic materials.

  • Rahnella aquatilis strain AY2000 produces an anti-yeast substance (AYS), however activity of the AYS has a declining tendency during storage. To investigate what has been decreased activity of the AYS, the AYS was treated with various physicochemical agents in this paper. The activity of AYS was decreased by heat treatment. Thiol reagent such as $\beta$-mercaptoethanol or dithiothreitol was also another factor decreasing the activity of AYS. However, pH, EDTA, and NaCl were not factors decreasing the activity of AYS. Use of methanol to precipitate the AYS was also decreased the activity of AYS. The activity of AYS was not lost after Sepharose S-400 gel filtration. However, the AYS activity was completely lost, when a polysaccharide and a unknown substance (230 nm absorption) among components of the AYS was separated by DEAE-cellulose chromatography. MIC of the AYS against S. cerevisiae was usually determined at $7.8-15.6{\mu}g/ml$.

  • This paper analyzes how Korea's trade intensity with major ASEAN countries changed from 2000 to 2005. For this purpose, we measured the trade intensity index, the trade complementarity index, and the special country bias index between Korea and ASEAN countries by the trade intensity index model developed by Yamazawa (1970). The OECD trade matrix was used as data. We found that Korea's trade intensity with Indonesia increased from 8.91 in 2000 to 10.88 in 2005 due to a considerable increase in Korea's special country bias with Indonesia from 9.58 in 2000 to 10.75 in 2005. Therefore Korea's special country bias with Indonesia should be enhanced further by increasing capital movements and reducing discriminatory tariffs and other import restrictions between Korea and Indonesia. It was also found that trade intensity between Korea and other ASEAN countries (i.e., Malaysia, Philippines, Singapore, and Thailand) shows a similar pattern of the above trade intensity between Korea and Indonesia except the trade complementarity.

  • A total of 79 Salmonella spp. were isolated from Pusan area in 2000. The serotypes of 79 Salmonella isolates were classified as 42 strains of S. typhi(53.1%), 24 strains of S. enteritidis(30.4%), 9 strains of S. montevideo(11.4%), 2 strains of S. typhimurium(2.5%), 1 strain of S. infantis(1.3%) and 1 strain of S. indiana(1.3%) strains(16.5%) of Salmonella sp. were isolated at May July, respectively. The isolates of S. typhi were sensitive to most sntibiotics except streptomycin. All isolates of S. typhi were especially sensitive to tobramycin, gentamicin, colistin, kanamycin, samikacin, sulfamethozazole/ trimethoprim, cefriaxone, ceftazdime, cifrofloxacin, cefoxitin and cefotaxime. Isolates of S. enteritidis wer presented higher resistance than isolates of S. typhi. Twenty-four strains of S. enteritidis were sensitive to kanamycin, amikacin cifrofloxacin, cefoxitin and cefotaxime, however 13 strains(54.2%) of S. enteritidis were resistant to carbenicillin, ampicillin and ticarcillin. Nine strains of S. montevideo were sensitive to most antibiotics except carbenicillin and streptomycin. Each 1 stain of S. indiana and S. infantis was sensitive to most antibiotics used in this study except streptomycin. Three kinds of resistant pattern (CB, SM, TE, AM, TC). In the case of S. enteritidis isolates, 9 kinds resistant pattern were detected. Most frequent resistant pattern of S. enteritidis isolates was CB, AM, TC type(16.7%)

  • 본 논문에서는 cdma2000 1X 및 1XEV HDR의 물리계층 구조와 위의 두 시스템이 TIA/EIA-95 시스템과 비교하여 개선된 점들을 살펴보았다.cdma2000 기술은 무선 인터넷 애플리케이션과 같이 서비스 사업자의 요구에 능동적으로 대처할 수 있는 플랫포옴을 가지고 있으며 그중 하나가 바로 HDR이다. 즉, 기존의 TIA-EIA-95 또는 cdma2000 1X망에 자연스럽게 융화되며, 트래픽이 링크간 비대칭적이고 벌스티한 특성을 가지며 요구되는 지연(delay) 및 QOS가 가변적인 인터넷 패킷 데이터 서비스와 같이 새로운 기능을 추가하는 것이 용이하다. 따라서 cdma2000 1X 와 HDR은 향후 일반화될 IP 서비스를 최적화하는데 있어서도 매우 효율적인 무선접속기술이다.
