Land use and social, cultural and environmental safety, which are adapted to natural environment, based on the traditional agricultural society, are on the verge of collapse because our rural community was developing around economy value. Rural landscape has not been certified compared with urban and natural landscape in importance by the standard of functional aspect, economic value and use demand, so cultural, historical, traditional and agricultural landscape native to rural community are not evaluated exactly. The Purpose of the study is a efficient plan and management for a essential rural landscape. Therefore We Make out a landscape diagram for efficient landscape plan and management and Selection of the Rural Landscape Management Area.

This paper describes two traffic shaping methods for VBR(variable bit rate) video bit streams encoded in the MPEG-2 syntax. Difficulties in control of VBR video traffic are lessened by traffic shaping. Burstness of single layer MPEG-2 can be reduced by performing intra-refresh in more than one consecutive frames. In two layer encoding of spatial scalability, burstness can be reduced by setting the temporal locations of GOP starting frame of a layVBR 트래픽을 허용한다는 것이다. 모든 AAL er, differently from the other. Queueing analysis shows that these two methods outperform conventional encoding schemes in terms of temporal and semantic QoS requirements.

The objectives of this study is to explain the perceived respiratory disease of female workers and to identify the affecting factors on their perceived respiratory disease. By the results of this study will be provided for basic data to develop health promotion program and to prevent the respiratory disease among female workers. The size of samples was 1875 female workers under forty years old. The data were collected method to identify the affecting factors on their perceived respiratory disease was used multiple linear regression analysis. The results were as follows; The average score of perceived respiratory disease by Cornell medical Index(CMI) is 1.92±2.16 and prevalence rate of respiratory disease is 3.6%. The results by multiple regression analysis were as follows: The affecting factors on CMI of respiratory disease were smoking, stress, workplace accident, status of indoor air pollution, respiratory disease in family, age, working period of current job(R^(2)=0.111). Respiratory health problem of female workers related to personal health behavior, job stress, indoor air-pollution of working place. Therefore the most effective health education for charge of health behavior(smoking) should be considered and must be provided the opportunity for health promotion program in workplace. Also the affecting factors on health status were working environments(indoor air pollution). Therefore, the most safety for working environments should be considered for the female workers in workplace.

Canine distemper virus(CDV) infection causes a fatal systemic disease in wide range of carnivore species, including domestic dogs. It has been a highly contagious disease of veterinary importance for centurise. Recently many researches show that qualitative RT-PCR for the detection of CDV was sensitive and specific method for the early and safe antemortem diagnosis of distemper by using whole blood regardless of clinical sign and pathological finding. Recently, results were correlated to clinical findings, anti-CDV neutralizing antibody titers, postmortem findings, and demonstration of CDV NP(nucleoprotein) antigen by immunohistochemistry. We have studied a quantitative real-time PCR assay for CDV in order to improve and broaden the clinical usefulness of RT-PCR assay. Total 37 samples including 9 clinically positive and 29 randomly selected ones have investigated. CDV RNA was extracted from whole blood. The isolated RNA was reverse-transcripted into cDNA followed by PCR amplification. The assay based on real-time PCR using SYBR Green I dye as quantitative method with a LightCycler. Calibration curves covered 30-3×10^(8) copies of CDV were created using cloned 240bp CDV cDNA of viral RNA. CDV was detected all in 8 positive samples whereas 8 in 29 randomly collected ones. The detection ranges of clinical CDV specimens were various from 3×10² to 3×10⁴ copies. Comparision of real-time PCR to conventional PCR showed equal sensitivity and specificity. But real-time PCR method has a merit of quantification as well as more rapid results than those of common RT-PCR. CDV can be accurately detected and quantified in the whole blood from the dog infected with CDV. This quantitative technique may improve the clinical utility of RT-PCR for the detection of CDV.

Tumor-infiltrating lymphocytes ('1°ILs) interact most closely with tumor cells and thus are more likely to reflect tumor host interactions accurately. But it is unknown whether such T cells are nonspecific inflammatory cells or a subset of specific host immune responses. In this study, there was no clear correlation between the infiltration of T lymphocytes in stomach cancer and the overexpression of c-ErbB-2 or increasing class I MHC expression on tumor cells. A positive correlation was seen between the presence of TILs in the tumor and tumors with diploidy by flow cytometric DNA analysis. The proliferative responses of Ills stimulated with IL-2, anti-CD3 mAb, or both were examined. When compared to normal mucosal-associated lymphoid tissue lymphocytes, the proliferative response of TILs to high dose IL-2 was minimal. A similarly poor response to anti-CD3 mAb plus IL-2 was also observed. The freshly isolated TILs exhibit reduced ability to proliferate in response to IL-2, anti-CD3 mAb or both. The microenvironment of the tumor suppresses the proliferative capacity of the TILs. The mechanism of this suppression remains unknown. It could be mediated by suppressor cells, by soluble substances within the tumor, or both. To examine this question, supernatants of stomach cancer cells (SNSNU-1) were tested for the presence of immunosuppressive factors. Human peripheral blood T-cells and tumor-draining lymph node lymphocytes (TDLNL) were incubated for 3 days with SNSNU-1 and then assessed for proliferative responses to PMA, anti-CD28 mAb, or both and for the inducibility to express IFN- r or IL-4 mRNA to PMA. Peripheral blood T-cells pretreated with SNSNU-1 were unable to proliferate in response to PMA, anti-CD28 mAb or both. SNSNU-1 also produces inhibitory activities of TDLNL proliferative response to PMA or anti-CD28 mAb and PMA (49%, 52%, respectively). In contrast, culture supernatants obtained from HEp-2, K562 or Daudi showed normal proliferative responsiveness of peripheral blood T-cells and TDLNL by PMA, anti-CD28 mAb or both.

To acquire an industrially useful biocatalyst for the enzymatic synthesis and production of various D-amino acids, 1,300 thermophiles isolated from the soil of Korea were analyzed for D-amino acid aminotransferase (D-AAT) activity. The enzyme activity was found from 110 strains of isolated thermophiles revealing its wide occurrence in thermophiles. Enzyme activity and thermal stability of the D-AAT producers were compared. Finally we have selected four thermophiles as producers of potent biocatalysts for the D-amino acid production; two therrnophiles, Bacillus sp. LK-I and LK-2, having higher specific activity and two thermophiles, B. stearothermophilus KL-01 and Bacillus sp. KLS-0l, having higher thermal stability than the D-AAT producers. Taxonomic and physiological characteristics of the four isolated thermophiles were described herein.
