The failure of rock slopes were influenced by weathering, which causes change in the shear strength. The weathering is also directly related to slaking and swelling characteristics. In the paper, the core of diameter 10㎝ was obtained by digging on rock slope of Kong-ju in Korea and the EDX (Energy Dispersive X-ray spectrometer) analysis was carried out to verified element of chief rock-forming minerals. Uniaxial compression tests, slaking tests, and point load test are performed to study engineering characteristics of conglomerate and red shale. As a results of slaking test, slaking index of conglomerate indicate range of 85.11-99.58 and shale indicate 58.37-99.23.Therefore, it is recognized that the resistance of shale to weathering decreases in shallow depth and it greatly influences the strength of rock. The result of uniaxial compression test and point load test show that the strength of sedimentary such as conglomerate and red shale has an influence on both weathering and saturation.

韓國産 夜行性 맵시벌科(벌目: 벌亞目)의 分類學的 硏究

이종욱,정종철,김기범,김정한,배지득,남상호 대전대학교 기초과학연구소 2002 自然科學 Vol.13 No.2

영남대 생물학과에 소장되어 있는 표본과 2001년 4월~2002년 6월 사이에 채집한 표본을 대상으로 하여 한국산 야행성 맵시벌의 분류학적 연구와 출현 현황 및 숙주 관계의 분석을 실시하였다. 분류학적 연구 결과 Gauld(1970)가 영국산 야행성 맵시벌을 대상으로 한 연구에서 기록한 Mesochorinae아과, Tryphonin-ae아과, Ctenoplematinae아과, Ophioninae아과의 4아과외에 Metopinae (Metopius속)를 추가하여 한국산 야행성 맵시벌류는 총 5아과 13속을 기록하였다. 또한 한국산 야행성 맵시벌의 출현 현황을 분석한 결과 야행성으로 잘 알려진 Mesochorinae아과의 Mesochorus속, Tryphoninae아과의 Netelia속과 Ophioninae아과가 전체 야행성 맵시벌 증 95%를 차지하였다. 속별 출현현황을 살펴보면 Netelia속이 393개체가 출현하여 가장 많은 수를 나타내었으며 Ophi-on속, Mesochorus속, Enicopilus속도 전체 출현 분류군 중 높은 비중을 차지하였다. 월별 현황을 살펴보면 전반적으로 4월에서 11월 사이에 걸쳐 나타나는데, Op-hioninae아과는 5월과 7월에, Tryphoninae아과는 6월에 집중적인 출현 빈도를 보였다. 숙주의 분류군에 따른 야행성 맵시벌의 기생 양상을 살펴보면 대부분이 나비목을 대상 숙주로 하고 있으며 Mesochorinae아과와 Ctenopelmatinae아과는 벌목에도 많은 종이 기생하는 것으로 나타났다. 특히 Mesochorinae아과의 Cidaphus속은 위생 해충으로 분류되는 기생파리과(Tachinidae)에도 기생하는 것으로 나타나 위생 해충을 구제할 수 있는 천적 분류군으로 연구될 수 있는 가능성을 보였다. 숙주의 식성에 따라 살펴보면 부식성의 먹이를 섭식하는 부식성(saprophagus) 숙주, 곤충의 유충을 섭식하는 식충성(entomophagus)인 숙주가 소수 출현하였고 기생생활(parasite)을 하는 숙주도 다수 출현하였으나 대부분의 야행성 맵시벌의 기생 대상 숙주는 주로 식물을 해하는 식식성 곤충(phytophagus)으로 나타났다. Nocturnal Ichneumonidae, which was called yellow-brown ichneumonoid, included several subfamilies adapted for nocturnal activity. Taxonomic study of nocturnal ichneumonoid has been investigated by Gauld(1975) but examination of Korean nocturnal ichneumonoid has not been provided until now. This present study: the taxonomic revision, Appearance state and Host-parasite relation analysis of nocturnal ichneumonoid, were examined using Korean peninsula specimens. As the result. approximately 13 genera referable to 5 subfamilies appeared regularly in light trap. Genus MetopiudSubfamily Illetopinae) were newly recorded in nocturnal ichneumonoid. Tryphoninae and Ophioninae, which were dominant in appearance taxa! occupied 96% of total numbers of individuals, and majority of them were taken from May to November. Nocturnal ichneumonoid are parasitoids of part of immature holometabolous insects(Coleoptera, Diptera, Hymenoptera, Lepidoptera). Lepidoptera is the most common hosts of nocturnal group except Mesochorinae and Ctenopelmatine. In large number of Mesochorinae are koinobiont hyperparasitoids of ectoparasitic or endoparasitic BraconiddHymenoptera), and, less frequently, of Tachinidae(Diptera1. Also, Ctenopelmatinae are koinobiont endoparasitoids of Symphyta and, rarely, Lepidoptera. Majority of nocturnal ichneumonoid hosts are phytophagous, feeding plant taxa, and many host of Mesochorinae taxa are parastoids, and a few host are saprophagus or entomophagus.

EIA-709.1 Control Network Protocol is the basic protocol of LonWorks systems that is emerging as a fieldbus device. In this paper, the protocol is implemented by using VHDL with FPGA and C program on an Intel 8051 processor. The protocol from the physical layer to the network layer of EIA-709.1 is implemented in a hardware leval. So it decreases the load of the CPU for implementing the protocol. We verify the commercial feasibility of the hardware through the communication test with Neuron Chip, based on EIA-709.1 protocol, which is used in industrial fields. The developed protocol based on FPGA becomes one of IP and we are able to implement SOC for the terminal device in the distributed control systems. Also, the result can be applicable to various industrial field because it is implemented by VHDL.

국내에서 채집한 진드기의 라임병 및 ehrlichiosis원인체 보균 상태를 조사하기 위하여 총 516마리 (Ixodes spp. 22마리, Haemaphysalis spp. 494마리)의 ixodid 진드기를 봄과 가을에 걸쳐 강원도 고산지대 일원에서 채집하였다. 수집한 진드기에서 DNA를 추출 ·정제한 후 추출한 DNA를 template로 이용하여 , Borrelia burgdorferi sensu lato 및 Ehrlichia spp.에 특이하게 반응하도록 제작한 primer를 이용한 중합효소연쇄반응 (polymerase chain reaction, PCR)을 실시하였으며, 이 결과를 oligonucleotide probe를 사용한 southern blotting을 통하여 다시 확인하였다. 총 516마리의 진드기중 B.garinii sensu lato DNA 양성 인 진드기는 68(13.2%)마리 (B. burgdorferi sensu stricto,2; B. afzelii,1; B. garinii,33; B.tanukii,8; B.turdae, 4)로 나타났으며 이 중 37 (7.2%)마리의 진드기 는 southern blot analysis에서도 양성으로 확인되었다. 또한 101 (19.2%)마리의 진드기가 Ehrlichia spp.에 대한 PCR에서 양성 이었으나, 이들 중 25 (4.8%)마리 만이 southern blot analysis에서 양성으로 확인되었다. 그러나 사람의 병인체로 추정 되는 human granulocytic ehrlichiosis (HGE) agent DNA를 보균한 진드기는 확인되지 않았다. 한편 라임병균과 ehrlichiosis원인체를 동시에 보균한 것으로 밝혀진 진드기가 3마리에서 (0.6%)확인되어,국내에서도 진드기 교상시 이들 두 가지 열성질환이 동시에 감염될 가능성이 있는 것으로 사료됨으로 진드기 매개성 열성질환에 대한 적절한 진단법 등을 보다 체계적으로 연구하여야 할 것으로 판단된다. To investigate the distribution of Borrelia Burgdorferi and human granulocytic ehrlichiosis(HGE) agent in ticks, adult ixodid ticks of Ixodes spp. and Haemaphysalis spp. were collected from the high mountain areas of Kangwon Province. Using DNAs extracted and purified in the collected ticks, polymerase chain reaction (PCR) was performed to amplify the specific nucleotide sequences of both agents. Of the 516 ticks, a total of 68 (13.2%) ticks was positive for Borrelia burgdorferi sensu lato with PCR analysis (2 for B. burgdorferi sensu stricto; 1 for B. afzelii; 33 for B. garinii; 8 for B.tanukii; 4 for B. turdae). However a little more than half of PCR-positive ticks (37/68) was found to be positive in the southern blot analysis with Bl6S oligonucleotide probe. One hundred and one (19.2%) ticks were positive for Ehrlichia spp. in PCR, and a quarter of them (25/101) was positive in southern blot with E16S oligonucleotide probe. But none of them was found to be the DNA of HGE agent. And 0.6% (3/516) ticks were positive for both of B. burgdorferi sensu lato and Ehrlichia spp. These findings might implicate the possibility of the outbreak of lyme borreliosis and ehrlichiosis in Korea, and more extensive studies may be need for the diagnosis of multiple tick-borne diseases.

The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

마우스에서 전기자극 스트레스의 면역조절 효과

김정범,박종욱,배재훈 대한생물치료정신의학회 1996 생물치료정신의학 Vol.2 No.2

전기자극 스트레스가 마우스의 면역계에 미치는 영향을 조사하기 위해 체액성과 세포성 면역반응을 조사하고, 이 면역반응 결과에 대한 면역조절 기전을 이해하기 위해 전기자극 스트레스가 사이토카인의 유전자 발현에 미치는 영향을 조사하였다. 생체내 면역반응을 평가하기 위하여 흰쥐 적혈구에 대한 특이항체생성반응은 스트레스군에서 대조군보다 항체생성반응이 감소하였다. DNFB에 대한 접촉성 과민반응 실험에서 T24는 스트레스군과 대조군 간에 차이가 없었으나 T48는 T24에 비해 스트레스군에서 증가를 보였다. Phytohemagglutinin으로 자극된 비장 단핵구의 증식에 미치는 영향을 알아보기 위해 ³H-thymidine incorporation 검사를 실시한 결과 스트레스군에서 대조군보다 세포증식반응이 증가되었다. 전기자극 스트레스에 의한 면역조절 기전을 이해하기 위하여 사이토카인의 유전자 발현을 조사한 결과 스트레스군에서 대조군에 비해 IL-2, IL-6의 유전자 발현이 억제되고 IL-1, IL-12,GM-CSF,MIF등의 유전자 발현에는 대조군과 차이가 없음을 보였다. 이상의 결과를 볼 때 전기자극 스트레스에 의해 체액성 면역반응이 저하된 현상은 면역반응 활성화와 항체 생성에 중요한 IL-2및 IL-6 유전자 발현의 억제와 연관이 있을 것으로 생각되며, 스트레스군에서 IL-2 유전자 발현의 억제에도 불구하고 mitogen에 의한 세포증식반응이 증가한 현상을 해명하기 위해서는 보다 다양한 실험조건의 적용이 필요하며 더 나아가 스트레스에 의한 동물의 행동반응 또는 신경내분비계에서 나타날 수 있는 변화들과의 연관성에 대한 계속적인 연구가 필요할 것으로 생각된다. To explore the molecular mechanisms by which electric footshock has immunomodulatory effects, the effects of electric footshock, on the humoral and cell-mediated immune responses of ICR mice and then the gene expression of cytokines in splenocytes, including interleukin-1(IL-1), IL-2, IL-6, IL-12, the migration inhibitory factor(MIF), and the granulocyte macrophage-colony stimulating factor(GM-CSF), were investigated. Mice were subjected to electric footshock for 3 days(two sessions a day, 11 footshocks a 31-min session). The humoral response was measured using ICR mice immunized with rat RBC. The cell-mediated immune response was evaluated by contact. hypersensitivity to 2,4-dinitrofluorobenzene(DNFB) and by phytohemagglutin(PHA)-stimulated splenocytes proliferation assay. In the stressed group, electric footshock suppressed significantly the anti-rat RBC antibody(P<0.05), but enhanced significantly T48 relative to T24 in contact hypersensitivity(P<0.01) and T-cell proliferation response(P<0.05) by PHA stimulation relative to the control group. The gene expression of IL-2 and IL-6 were suppressed significantly in PHA-stimulated splenocytes, but that of IL-1, IL-12, GM-CSF and MIF were not. In conclusion, suppressed IL-6 gene expression seems to account for suppressed humoral immune response. In spite of enhanced cell-mediated immune response, the result is that IL-2 gene expression was suppressed, which suggests the two putative mechanisms. Firstly, while in the stressed group production of IL-2 occurs rapidly and thereafter declines abruptly, in the control group that of IL-2 occurs slowly and thereafter declines gradually. Secondly, there may be certain detouring circuits extending the signal conduction system by IL-2 except the usual signal conduction system.

To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.
