The underachieved students who don't reach normal step come to lose their interests in mathematics. Also the increasing loss of pre-study cause learning barrier. In order to help the underachieved to increase self-study ability and supplement basic ability for normal class, this study has presented them with step-type assignment materials and helped them to team more actively. So I have examined the effects of achievement, interests, and attitude. I have also tried this study for step-type leveled curriculum of high school beginning in the year of 2002. The conclusions can be got as follows. 1.So as to minimize the loss of pre-study and increase loaming ability caused by personal difference, when developed not graded step-type assignment materials have been applied to the underachieved, meaningful differences have been shown in achievement owing to their improved solving ability. 2.The materials have helped them to team deficient pals voluntarily. They also have been efficient in increasing attitude. However, little meaningful differences have been shown in their interests of mathematics. On the bases of problems and conclusions shown in the proceedings of this study for the underachieved in mathematics, the following suggestion can be got out. 1.After considering the leveling and systematics of mathematics, the contents for the step learning should be reconstructed. Also both the class strategy fitting to cognitive structure and type of the underachieved, and proper opportunity of not-graded assignment study should also be presented. 2.Organizing assignment class should be classified from lower to higher conception gradually. Furthermore abstract and conceptional class should be avoided. Instead the basic law and principle of simple numbers and formula, and generalizing process should be introduced. So problem difficulty should be lowered so that students can study voluntarily. 3.With these things of introducing many lower intuitions and examples, checking their performance, reinforcing, rewarding, and consulting activities, we must teach students so that they have affirmative attitude and confidence in mathematics.

수행평가방법 중 서술형 평가를 적용한 학습이 학력신장에 미치는 영향 : 고등학교 공통수학을 중심으로

노영순,류춘식 한국학교수학회 2001 韓國學校數學會論文集 Vol.4 No.1

This research is about how the adapted learning of descriptive assessment problems influence on the extension of the ability of the students. As a result, adapted learning of descriptive assessment problems totally led to positive effect, and according to the analyses of behavioral objectives divided into knowledge, comprehension and problem solving, they had more effect on the ability of students' problem solving. Learning attitude of the students were changed into self-centered learning attitude and interest on the subject of mathematics were highly increased since the research had started. If we adapt this research to the learning of mathematics after we develop various problems that can develop creativity, I'm sure that it will be a effective way for both extension of the ability and problem solving ability of the students.

본 연구의 목적은 중등학교 수학과 학습에서 교육정보화를 실현하기 위한 수학교사들의 정보화기기 활용 실태에 대하여 조사하고 이에 따른 학습 효과에 대하여 현장 수학 교사들이 생각하고 있는 의식을 조사 분석하고 그에 대한 문제점을 찾고 그 개선방안을 제시하는 것이다. The purpose of this paper is to investigate (in order to realize the educational information) the actual condition of application of information machineries for learning of mathematics by mathematics teachers in a secondary school. And we find out the point at issue about application of this machineries and presents reform measures after we research and analyze school mathematics teachers' consciousness for learning effect based on this investigation.

본 눈문에서는 fuzzy difunctional relation 동치조건들을 소개하였고 이를 이용하여 fuzzy difunctional relation과 관련된 일부 결과를 제시하였으며 또한 반군에서의 퍼지합동관계를 α-cut로 특성화 하였다. In this paper, we shall introduce equivalent conditions of the fuzzy difunctional relation, give some results in connection with fuzzy difunctional relations and characterize the fuzzy congruence relation on a semigroup in terms of its α-cut. Also, closed relationship between fuzzy difunctional relations and fuzzy congruence relations will be revealed.

Rhabdomyosarcoma, which is a very rare and highly malignant disease in urologic field, has three categories-pleomorphic, alveolar, embryonal, and may arise from any part of the body that contains embryonal mesenchyme, whether striated muscle tissue is present or not. The common site in the genitourinary tract are prostate, bladder, and vagina. Herein we experienced a rhabdomyosarcoma of the pelvic cavity and reviewed literature briefly.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.

목적 : 양성 갑상선 결절 환자에서의 PEI의 치료효과 및 부작용을 알아보고자 하였다. 방법 : 양성 갑상선 결절 환자 88명을 대상으로 초음파 소견에 따라 낭종성 결절, 복합성 결절, 고형성 결절 등 세 그룹으로 분류후 전체 및 각각에 대한 PEI의 치료효과 및 부작용을 조사하였다. 결과 : 양성 갑상선 결절 환자 88명을 PEI로 치료후 결절의 크기가 50%이상 감소한 경우는 전체 환자중 77.2%이었고 각 결절별로 살펴보면 고형성 결절에서 52.6%, 복합성 결절에서 72.4%, 낭종성 결절은 92.5%이었다. 부작용은 동통, 결절내 출혈, 감염, 결절의 누출등이 있었으나 대부분 무증상이었다. 결론 : PEI는 양성 갑상선 결절 환자증 적응증을 잘 살펴 고려해 볼 수 있는 치료법이라 생각되며 특히 낭종성 결절 환자에서 주사기에 의한 흡인후에 재발한 경우 일차적인 치료로 PEI를 고려해 볼 수 있겠다. Ultrasonography(US)-guided percutaneous ethanol injection (PEI) has been performed for the treatment of autonomous functioning thyroid nodules, thyroid cysts, & cold thyroid nodules. The author studied the efficacy of PEI in the treatment of benign cold thyroid nodules both solid and cystic (complex & pure). Eighty-eight euthyroid outpatients (age:44.2±13.9years, 75 women and 13 men) with benign cold thyroid nodules or simple thyroid cysts (69 with a single nodule and 19 with a prominent nodule within multinodular goiter) were includied in this study. After PEI, each subtype of thyroid nodules was divided into three groups in according to volume reduction complete response (90% or more of volume reduction), partial response (50% or more of reducton but below 90%), and failure (below 50% or increase in size) group. Overall response rates of PEI for benign thyroid nodules were complete 45(51.1%), partial 23(26.1%), failure 20(22.7%). In 20 cold solid nodules, complete response was observed in 6(30.0%), partial response in 5(25.0%), and failure in 9(45.0%). In 28 complex cysts, complete response was observed in 8(28.6%), partial response in 12 (42.9%), and failure in 8(28.6%). In 40 pure cysts, complete response was observed in 31(77.5%), partial response in 6 (15.0%), and failure in 3 (7.5%). Side effects comprised pain 8 (9.2%), intranodular bleeding 13 (14.6%), extracapsular leakage 1(1.1%), infection 1 (1.1%), increased size l(1.1%), and none 64(72.7%). PEI may prove a safe & effective tool for the therapy of cold thyroid nodules in selected cases and may be the treatment of choice of recurrent thyroid cysts. However, further investigation involving a larger number of patients and a longer follow-up is needed.
