The important goal of mathematics education is to help students develop the ability to solve problems rationally and to think mathematically. In this case study it is concluded that the active and positive participation on the part of students could be achieved in the small group cooperative learning rather than the teacher-centered classroom activity. As such desirable attitude of the student largely depends on the teacher's will, his continuous interest and effort are urgently demanded. We hope that this study will contribute to the development of the teaching-learning methods of mathematics.

N/A This study was conducted to examine rice growth duration by analyzing agricultural climatic conditions at different latitudes in unified Korea. The climatic conditions of nine sites from Wunggi (latitude 42N) to Jeju (latitude 31N) were examined in this study. The rice growth duration of various cropping patterns was determined by analyzing consecutive days when effective daily mean air temperature was suitable for rice growth from the first seeding date to the last maturing date. The rice growth duration in Wunggi located in North Korea was available 138 days for machine transplanting, 115 days for direct seeding on dry paddy cultivation, and 97 days for direct seeding on a flooded surface with cultivation after seeding. On the other hand, the rice growth duration in Kwangju (latitude 35N) located in South Korea was 195 days for machine transplanting, 180 days for direct seeding on dry paddy cultivation, and 170 days for direct seeding on a flooded surface cultivation after seeding.

남북한을 하나로 묶는 벼 재배 농업기후지대를 구분하기 위하여, 남한에서 구분하여 활용하고 있는 방법을 바탕으로 북한의 24개 지역에 대한 평년기후 자료(1976-1985)를 분석 평가하였다. 벼농사에서 중요하게 취급하는 생육시기별 기후요소인 4월에서 6월까지 강수량, 8월의 평균기온, 7월부터 9월까지 평균기온 등과 작물기간을 분석하여 북한의 벼농사에 대한 농업기후지대를 구분하였다. 가. 북한의 벼 재배 농업기후지대는 Ⅰ개마고원지대, Ⅱ 백두동서산간지대, Ⅲ 함경동해안북부지대, Ⅳ 북부내륙중간지대, Ⅴ 함경동해안남부지대, Ⅵ 북부 평야지대, Ⅶ 북부서해안지대 등 7개 지대로 구분되었으며, 남한과 연결되는 1 태백고냉지대와 2 태백준고냉지대를 포함하면 9개 지대였다. 나. 북한의 4∼6월 강수량은 152∼366 ㎜ 범위로서 남한의 한발(가뭄) 우려지대인 영남분지지대 (11지대), 동해안북부지대(17지대) 동해안중부지대 (18지대) 보다 적었다. 다. 벼의 냉해 위험 판단 온도인 8월 평균기온 23℃ 이하, 7∼9월 평균기온 22℃ 이하로 경과되는 지대는 Ⅰ개마고원지대, Ⅱ 백두동서산간지대, Ⅲ 함경 동해안북부지대, Ⅳ 북부내륙중간지대, Ⅴ 함경동해안남부지대 등 5개 지대였다. 라. 북한에서 작물기간이 150∼160 일로 중생종 벼재배가 가능한 지대는 북부서해안지대 (Ⅶ지대) 뿐이며, 8월 평균기온 20℃ 이하로 벼 재배가 불가능한 지대는 개마고원지대 (Ⅰ지대)와 백두동서산간지대 (Ⅱ지대)이며, 나머지는 극조생종 또는 조생종 재배지대로 판단된다. 마. 쌀의 기후생산력지수가 0.90∼0.96인 지대는 함경동해안남부지대 (Ⅴ지대), 북부평야지대 (Ⅵ지대), 북부서해안지대 (Ⅶ지대) 등이며, 개마고원지대 (Ⅰ지대)와 백두동서산간지대 (Ⅱ지대)는 0.57∼0.75로서 벼 재배가 불가능한 지대로 판단된다. To unify an agroclimatic zone for rice production of South and North Korea, the normal climate data(1973-1986) from 24 sites in North Korean area were evaluated based on the method of agroclimatic zoning in South Korea. Amount of rainfall from April to June, monthly mean air temperature in August, daily mean air temperature from July to September, and crop period were major climatic elements to divide agroclimatic zones. The divided seven North Korean agroclimatic zones for rice production wereⅠ. Gaema Plateau, Ⅱ. Paektu Eastern & Western Mountainous, Ⅲ. Hamgyong North Eastern Coastal, Ⅳ. North Inland Intermediate Mountainous, Ⅴ. Hamgyong South Eastern Coastal, Ⅵ. Northern Plain, and Ⅶ. North Western Coastal. Also there included two zones, 1. Taebaek Alpine Zone and 2. Taebaek Semi-Alpine Zone that were continuous from the South Korean zone. The amount of rainfall from April to June in North Korean areas ranged from 152 ㎜ to 266 ㎜ that were less than those in the drought zones of South Korean areas. The hazardous daily mean temperature to cool weather injury of rice plant, below 23℃ in August or below 22℃ from July to September appeared in five zones except, Ⅵ. Northern Plain and Ⅶ. North Western Coastal in North Korea. The possible zones to cultivate intermediate maturing rice in North Korea that, needs 150-160 days of crop period was only Ⅶ. North Western Coastal Zone. Extreme early or early maturing rices were possibly grown in the four zones, Ⅲ. Hamgyong North Eastern Coastal, Ⅳ. North Inland Intermediate Mountainous, Ⅴ. Hamgyong South Eastern Coastal, and Ⅵ. Northern Plain, but any rices in I. Gaema Plateau and Ⅱ. Paektu Eastern & Western Mountainous. The rice productivity index showed 0.90-0.96 in three zones, Ⅴ. Hamgyong South Eastern Coastal, Ⅵ. Northern Plain, and Ⅶ. North Western Coastal.

Background/Aims: To date, an effective salvage chemotherapy regimen for the treatment of refractory or relapsing non-Hodgkin`s lymphoma (NHL) has not been discovered. This study was conducted to evaluate the efficacy and safety of gemcitabine, etoposide, cisplatin, and dexamethasone in relapsed or refractory NHL patients. Methods: All patients had histologically proven relapsed or refractory NHL. Treatments consisted of gemcitabine 700 mg/m2 by continuous i.v. on days 1 and 8; etoposide 40 mg/m2 by i.v. on days 1-4; cisplatin 60 mg/m2 by i.v. on day 1; or dexamethasone 40 mg by i.v. on days 1-4 (GEPD) every 21 days. The primary end point was the patient response rate following two cycles of treatment. After two cycles, stem cells were harvested using mobilizing regimens (ESHAP or GEPD plus filgrastim), and this was followed by autologous stem cell transplantation or four additional cycles of GEPD. Results: Between January 2005 and January 2006, 20 patients (13 males and 7 females) were enrolled in the study. The median age was 53 (range 16-75) years. The most common histology was diffuse large B-cell lymphoma (n=10). The median follow-up duration was 5.2 (range 1.0-16.0) months. After two cycles, the overall response rate was 50.0% (10/20), including two complete responses and eight partial responses. The doselimiting toxicity was myelosuppression. Grade IV neutropenia and thrombocytopenia occurred in 13 (65.0%) and 6 patients (30.0%), respectively. The median number of CD34-positive cells collected was 6.0 (range, 2.8-11.6)×10(6)/kg. Of the 17 patients<66 years of age, 4 (23.5%) proceeded to autologous stem cell transplantation. Conclusions: GEPD chemotherapy in patients with refractory or relapsed NHL was effective as a salvage therapy and helpful for stem cell harvest followed by autologous transplantation.

Background : Methicillin-resistant Staphylococcus aureus (MRSA) is the major pathogen of nosocomial infections. There are many reports that MRSA nasal cariers play a major role in the transmission of MRSA. We studied to assess the nasal carriage rates, therapeutic effects of nasal carriers and control of MRSA outbreak in a tertiary, acute and educational hospital. Methods : From 1990 to 1997, eight MRSA epidemics were detected and investigated for outbreak control. We surveyed the MRSA colonization of anterior nares and hands of health care workers (HCW). MRSA was identified by staphylococcal broth, mannitol-salt-agar, Muller-Hinton-oxacillin agar. To identify the permanent carriers in the HCWs, the nasal swab was done weekly for 3 weeks. Two percent povidone iodine ointment or 2% mupirocin ointment was applied topically to treat the permanent MRSA nasal carriers. Results : Of eight MRSA outbreaks, five epidemics occured in the intensive care unit, all of them occurred in surgical departments and five of them occurred in winter seasons. For eight MRSA outbreaks, 351 HCWs were surveyed. The rates of transient carriers was 10.8% (38/351) and the rates of that were 9.0% (10/111) in medical doctors (MD), 12.5% (24/192) in registered nurses (RN) and 11.4% (4/35) in aid nurses (P=0.470). The rate of permanent carrier in doctors was 1.8%, and that in RNs was 3.7% (P=0.490). After topical therapy with 2% povidone iodine ointment or 2% mupirocin ointment for permanent carriers, MRSA was not identified for 2 months follow up. Conclusion : In MRSA epidemics, the rate of the transient carrier rate of MRSA in HCWs was 10.8% and the rate of the permanent carrier was 2.6%. The difference of carrier rates in HCWs was not significant statistically. The therapy for the permanent nasal carriers in HCWs with two percent povidone iodine ointment or 2% mupirocin ointment was very effective. And MRSA outbreaks were ended and controlled for 6months follow up. (Korean J Infect Dis 33: 194∼201, 2001)

In this paper we investigate (n+1)($n{\geq}3$)-dimensional contact CR-submanifolds M of (n-1) contact CR-dimension in a complete simply connected Sasakian space form of constant ${\phi}$-holomorphic sectional curvature $c{\neq}-3$ which satisfy the condition h(FX, Y)+h(X, FY) = 0 for any vector fields X, Y tangent to M, where h and F denote the second fundamental form and a skew-symmetric endomorphism (defined by (2.3)) acting on tangent space of M, respectively.
