This study was carried out to evaluate the status of the groundwater quality for paddy fields irrigation in Korea. Water samples were collected at 130 sites throughout the country. Samples were collected at three seasons-April, July and October-in 2000. According to our survey, the groundwater was found to be suitable for irrigation purpose. Average EC was shown 0.286 dS/m. Nitrate-nitrogen and Cl^(-) concentration was 5.6 ㎎/L, 32.95 ㎎/L which satisfied the Korean Standards for Irrigation Water. Nitrate-nitrogen concentration in each province was shown as following orders: Jeju (11.17 ㎎/L) > Chungnam (8.16 ㎎/L) > Gyeongbuk (6.64 ㎎/L) > Gyounggi (5.91 ㎎/L) > Chungnam (4.95 ㎎/L) > Gyeongnam (3.91 mgk) > Jeonbuk (3.50 ㎎/L) > Jeonnam (3.27 ㎎/L) > Gangwon (2.91 ㎎/L). The concentration by sampling seasons were October (6.62 ㎎/L) > July (5.88 mg&) > April (4.78㎎/L). As the soil of Jeju Province is usually derived from volcanic ash soils mainly used for upland drops, it may influence the nitrate-nitrogen concentration of groundwater. The amount of rainfall also influence the water quality. But the COD_(Cr), were shown April (3.17㎎/L) > July (2.91 ㎎/L) > October (2.40 ㎎/L), it is highly related in the basal dose of organic matter fertilizers. This study demonstrated that groundwater quality was suitable for irrigation, but continuous monitoring is recommended for agricultural policy and developing OECD agricultural environment indicators.

Purpose: The gastrointestinal (GI) tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), which is increasing in incidence, but there is no established optimal treatment modality. Thus, this study was investigated the clinicohistologic feature, the therapeutic modalities, and the prognosis for GI-NHL, as well as the factors affecting it. Methods: We retrospectively analyzed 45 patients who had been diagnosed as having GI-NHL and had been followed up from July 1994 to February 2005 at Soonchunhyang University Hospital. The patients were divided into groups according to the site of origin and to various other features, and the survivals of the various groups were compared. The modified Ann Arbor system and WHO classification were adopted for staging and histopathologic classification, respectively. Results: GI-NHL of the stomach, small bowel, ileocecal region, and colon occurred in 28 patients (62.2%), 5 patients (11.1%), 3 patients (6.7%), and 8 patients (17.8%), respectively, In one patient, the entire gastrointestinal tract was diffusely involved. The median age of patients was b5 years (25~78 years), and male-to-female ratio was 1:1.1. Fourteen patients were in stage Ⅰ, 24 in stage Ⅱ, 4 in stage Ⅲ, and 3 in stage Ⅳ. Surgical resection was performed in 19 patients, and combination chemotherapy was performed in 43 patients. Surgical resection only was performed in 4 patients, Chemotherapy only was performed in 26 patients. The expected overall 5 year survival of 45 patients was 39.6%, and there was a significant survival difference between the stages, but between sites of origin (p=0.842). The most important factors influencing the survival was the stage and other factors were not significant. Conclusion: The stomach was the most common site of GI-NHL. Most GI-NHL were localized Stage was the most important prognostic factor. However, Prospective randomized studies are needed to approve the therapeutic modality.

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.

In ethanol and pyridine, the molar extinction coefficents of nickel( II ) complexes of A, B, and C except D increase with the variation of time. From the result it is known that ethanol and pyridine may interact with the complexes, and then they may also remove a proton of the ammonium group of the ligand to form the five coordinate complexes of nickel( II )- ammonium dithiocarbamates. It is suggested that the rate-determining step is a process of deprotonation of the ammonium group in nickel( II )-ammonium dithiocarbamates complexes.

본 연구는 넙치에 대한 수온 변동 자극의 영향을 생체 방어적인 측면에서 검토하고자 하였다. 수온 변동 자극은 매일 18℃에서 25℃까지 상승과 하강을 반복하는 방법을 사용하였으며 그 기간은 30일간 지속하였다. 실험어는 온도변화를 주기 시작한 후 28일째까지 무작위로 채포하여 말초혈액 중의 백혈구 수, 전혈의 식작용능, 활성산소, 환원능, chemiluminescence(CL) response 및 lysozyme용균능과 같은 각종 비특이적 생체방어와 관련한 실험을 수행하였다. 수온 변동 자극을 주기 시작한 후 1일째부터 시작하여 1주일 이내에 약 18%의 넙치가 폐사하였으며 이후에는 대조구와 유사하였다. 또한, 수온 변동 자극을 준 실험구의 호중구 수는 2주째에 유의적인 증가를 보였으며, 림프구 수는 2일과 3일째에 감소하였으나 1주째부터 대조구와 유사한 수준으로 회복되었다. 실험구에서는 식작용 결과 식균율과 식균지수에서 이물질 투여 후의 반응이 늦게 나타났다. 식세포의 활성을 조사한 NBT reduction 실험에서는 실험 기간 동안 대조구와 유사한 경향ㅇ르 나타내었다. 또한, CL response의 경우, 실험구는 온도 변동 자극초기에 대조구에 비하여 유의적으로 낮았다. 그리고, 식세포가 분비하는 용균성 효소인 점액 내 lysozyme의 활성은 실험 기간 동안 실험구에서 낮게 나타나는 경향을 보였다. 이러한 여러 가지 비특이적 생체 방어 반응의 저하 현상은 수온 변동 자극 초기에 나타났으며, 1주일 정도 지속하면 그 환경에 적응하는 것을 알 수 있었다. 그리고 이러한 현상은 이들이 초기 폐사 발생과 어떤 상관 관계에 있는 것으로 생각되었다. This study was performed to know the effects of stress nduced by the daily fluctuation of water temperature fro 18? to 25? up and down for 30 days on the defence mechanism of olive flounde,r Paralichthys olivaceus. To make clear the temperature stress on the defense mechanism of the tested fish, several factors of immune response such as counting of leucocyte appearance in periopheral blood, phagocytic activity in whole blood cells, nitroblue tetrazolium(NBT) reduction, chemiluminescence(CL) response, and lysozyme activity were investigated at 28 days after giving the change of water temperature. The fish was controlled under the none feeding condition during experimental period. Mortality of the tested fish was rapidly increased up to 22% within the first one week of the experimental period without any additional stress factors. The number of neutrophil of peripheral blood in the tested group was significantly higher than the control group at the 2nd week, but the number of lymphocyte was significantly lower than the control group at the 1st and 3rd day of the experimental period, respectively. In the NBT reduction test, the activity of macrophage in the control group fish was the highest on the 7th day while that in the tested group was on the 3rd day. Also, the phagocytosis of tested group against formalin killed cells was retarded compared with the control CL response of the tested group was significantly lower from 2nd to 5th day of the experimental period than the contro. The lysozyme activity of tested group was remained higher during the experimental period than the contro. Even through the tested fish showed different results in some non-specific factors of immune responses between tested and control group fish, olive flounder seems highly adaptable in repeated water temperature change in condition after one week under the given temperature fluctuation range

This study was intended to examine whether the existing player assessment formulas by the sports game factors sufficiently explained/assessed a quality of games for a high reliability between the calculation-relevant parties in calculating a part of sports game results which impacted the sports player assessment, and to investigate why a difference between the sports game results and an evaluative result of player'ss actual value occurred, This analysis assumed that there was a contradiction in the player assessment for the sports game results, Searching how the players assessment has been done so for and what advantages and disadvantages of assessment are, could be a basis for structuring the assessment model. The model for the study analyzed the Power Ranking Formula per position expressed by Sports Cosun (records×(40/total playing time), Rank ER Index of NBA (ER=A-B/total number of athlete play), assessment formula of KBL's player contribution (assessed score of sports game results =extra score per item - deduction per item), NSP/SP formula of Harder, the contribution formula of Sports Chosun (contribution =points +rebound +assist +steal+ block +defense +minutes]-[error =number of failed shootings]), and ATR formula evaluating the point guard (ATR=assist (error), First, 'Sports Chosun' has the meaning of players comparison per position, but cannot do the relative comparison between positions and doesn't provide an exact mathematical information, Second, ER has a similar computing method to the formula of 'Sports Chosun' except that its mathematical information is more concrete. It is not reasonable method to evaluate all players at the same time, Third, KBL's formula accepted a diversity of assessment methods compared with other formulas, There are factors of addition/deduction even in some section, It attempted to carry out the player assessment such as granting the same weight in a concrete way, However, variables which are absolutely necessary for the assessment of underground results and extension of addition/ deduction need to be generated. Also, an objectivity of weight for a removal of voluntary grant is required, Forth, ATR formula evaluates the part of player's ability, but nobody can know whether the results are influenced by any role, Compared with other formulas, this formula is very improper, Fifth the formula of 'Sports Seoul! is almost consistent to the formula that deducts the weight in KBL formula, It is very similar to the KBL formula except an easy calculation of the formula, Consequently, a careful consideration is required, Sixth the formula of Harder seems to have the save context of flow as the formula of KBL and 'Sports Seoul'.

This study identifies the vertical functional differentiation of commercial facilities in apartment complexes of new towns in the microscopic landuse level. The data used in the study are originally from the previous study by Kim and Song (2000). It is properly cleaned up for the analysis in the study. This study constructs two hypotheses. They are ; 1) vertical functional differentiation of landuse in commercial facilities would exist, 2) vertical functional differentiation of lease rate in commercial facilities would exist. This paper suggests conclusions about type of industry ; 1) which is influenced of accessibility, and more influenced of lease rate, 2) which is only influenced of lease rate, 3) which is only influenced of accessibility. Consideration of horizontal location characteristics and external characteristics incoperated with vertical location characteristics would provide more reliable results and identify inherent relationships between them. It remains for future research.
