본 연구는 채소작물에 알맞은 양액재배용 배지를 구하기 위해 수행되었다. 사용된 채소 작물은 샐러리, 엔다이브, 결구상추이었으며 2가지 사용된 배지는 필라이트와 암면(대,소)이었다. 이용된 채소작물들의 생장특성은 필라이트 재배시보다 암면재배시 양호한 것으로 나타났다. 샐러리와 엔다이브는 작은 암면을 사용했을 때가 큰 암면을 사용했을 때보다 생육이 양호했으며 결구상추는 반대로 나타났다. 그러므로 본 실험에서 사용된 채소작물들에 알맞은 양약재배 배지는 필라이트 재배방식보다는 암면인 것으로 추측되며 암면의 크기가 생장에 영향을 끼치는 것으로 생각된다. This study was carried out to decide a optimum medium for three vegetable crops in a soilless culture. The vegetable crops used were celery(APium graveolns L.), endive(Cichorium endivia L), and head lettuce(Lactuca sativa L. var, Capitata) and media used were a perlite and a rockwood with a nutrient film technique(NFT). Growth characteristics of the vegetable crops were investigated in early two stages. The vegetables appeared to grow better in NFT(rockwood) system than in a large rockwood system, while head lettuce showed better growth in a large rockwood system. Therefore, it may be concluded that an optimum best hydroponic system fot the vegetables is a rockwood system, and that the size of rockwood is a significant influence on the growth of the vegetables.

Backgrounds : Many cancer patients, such as Hepatocellular carcinoma(HCC), have a compromised cellular immune system. Several lympocytes subpopulations are involved in immunosurveillance against tumors. We try to evaluate on alteration of peripheral T cell subsets, NK cell and NK cell activity in patients with HCC. Materials and Method : Our study contain 257 patients with chronic liver disease. Of the 257 patients, 147 patients were chronic hepatitis, 44 patients were liver cirrhosis, 66 patients were Hepatocellular carcinoma. We distributed these patients to 3 groups due to cause, chronic hepatitis B (1st group, n=183), chronic hepatitis C (2nd group, n=52), alcoholic liver disease(3rd group, n=22). This study analysis ratio of CD3+, CD4+, CD8+, CD56+ T cell and NK cell activity. Results : The percentage of CD3+ and CD8+ cells were significantly decreased in LC and HCC groups. The activity of NK cells was significantly decreased in HCC than hepatitis group in HBV group. But not different in HCV and alcohol groups. NK cell and NK cell activity were significant decreased in HCC of younger patients (below 40 years) than older patients (above 60 years). Conclusions : Our study showed HCC was altered cellular immune system and decreased activity of NK cells. On the basis of this results, it can be suggested that decreased activity of NK cells according to age may be related to differnce of common age, prognosis and response of immune therapy.

In this paper, we develop a detailed full dynamic model which includes various rough terrains for 6-wheel skid-steering mobile robot based on the real experimental autonomous vehicle called Dog-Horse Robot. We also design a co-simulation for performance comparison of path tracking algorithms. The control architecture in the co-simulation can be divided into two levels. The high level control is the closed-loop control of path tracking to follow a given path, and the low level is concerned about torque control of wheel motion. The simulation using the mechanical data of the Dog-Horse Robot is performed under the Matlab/Simulink environment. We also simulate and evaluate the performance of the model based adaptive controller.
