Ⅰ. I made this research by the following purposes and necessities. A. Necessity of Research 1. Elementary school teachers show some resistant responses to the curriculum based on the modernized curriculum in elementary school mathematics. 2. The resistant responses in general are as follows; (a) Insufficiencics in understanding of new contents of the curriculum. (b) Inadequacies for the physical and mental development of children. (c) Lacks of systematization in elementary mathematics resulted from the merely scattered enumerations. (d) Inadequacies of considerations for mathematic thinking. 3. It is urgent and quite natural that we should revise the above stated responses and improve the curriculum for the normal development in mathematics by finding out the good materials and the effective application of them. B. Objective of Research According to the above necesity of research, this research does not deal with the evaluation materials simply for the achievement measure, but deals with the closely related evaluation materials in 1. what to teach-a problem in the curriculum, and 2. how to teach-a problem of teaching method. Consequently this is intended to maximized the results of mathematics education by 1. developing the mathematic thinking and 2. finding out the method fit for the physical and mental growth 3. setting up the systematic relations between the earlier, middle and latter grades at the elementary school. Ⅱ. The outline of the research which was performed is as follows A. Collecting and Studying the evaluation materials already developed.(home and abroad) B. Surveying and analysing the resistant responses both in the curriculum and in actual teaching. C. Preliminary survey of children(surroundings, I. Q test etc.) D. Making the evaluation materials. 1. I limit the scope of research infield of set. 2. Framing guidance objectives of the set domain through all the grades of primary school childre. 3. Scheduling dichotomous taxonomy of educational objectives according to the above guidance objectives. 4. Making up evaluation items on the basies of the above taxonomy. 5. The examination of achievements according to the above evaluation data (application to the fouth grade and the sixth grade)

The wireless broadband (WiBro) system supports high quality internet data services with medium user's mobility. Towards this end, the system uses orthogonal frequency division multiple access (OFDMA) technology and the same frequency in every cell. To provide high-speed seamless services, handover functionality is needed. In this paper a handover algorithm for the WiBro system is proposed. Two kinds of OFDM channels are considered in the algorithm : diversity channel and safety channel. The handover algorithm is composed of intra-cell handover and inter cell handover using safety channels. In particular, the safety channel is used for the mobile users when the received signal quality is degraded. Performance analysis results show that the quality of service can be significantly improved by reducing the interference effect among OFDM channels.

This research was performed to optimize the anaerobic pretreatment of slurry type swine wastewater for the subsequent nitrogen and phophorus removal. Step-wise increases in Organic Loading Rate(OLR) and decreases in Hydraulic Retention Time(HRT) were utilized in Upflow Anaerobic Fixed Bed(AFB) reactor at mesophilic temperature(35℃). The maximum methane prodution rates of 1.16 v/v-d was observed at an HRT of 12 hours. TCOD removal efficiency of 75% at an HRT of 2 days and 41% at an HRT of 12 hours were obtained respectively. It is likely that the influent COD concentration of 3,000 mg/L for the subsequent biological nutrient removal system could be supplied from the anaerobic pretreatments operated at an HRT of 12 hours(OLR 12g CODL-day). During AFB operation alkalinity showed 800- 1,500mg/L as CaCO_(3) at all HRTs. It could play an important role for compensating pH drop caused by nitrification. The COD/TKN ratio of 6-14 at all HRTs, COD/TP ratio of 30-50 at an HRT of 1 day and proper buffering capacity and pH of the effluent from the anaerobic fixed bed could be adequate substrate condition in the following nitrogen and phosphorus removal. In conclusion, when AFB was operated at an HRT less than 1 day, the system could be optimized to reach an efficient anaerobic pretreatment for swine wastewater and the subsequent biological nutrient removal.

A 3 month-old male dog with clinical signs of anorexia, soft stool, ocular and nasal discharge, cough and respiratory distress was submitted to the Cheju National University for diagnosis. At necropsy, tan to purple-red sublobar to lobar consolidations were presented in apical and cardiac lobe of lung. Histopathologically, severe diffuse bronchointerstitial pneumonia with necrotic bronchiolitis was noted in the lung. The demyelinating encephalitis and astrocytosis were presented in cerebellum and cerebrum. Numerous round, ovoid or cluster of tachyzoites were also identified in alveolar lumen, alveolar wall and cytoplasm of macrophages in the lung. The orgasnisms were demonstrated as Toxoplasma (T) gondii by immunohistochemistry. Intranuclear or intracytoplasmic eosinophilic inclusion bodies were seen in the glial cells of the cerebellum. Canine distemper virus (CDV) specific antigens were demonstrated in the cerebellum by the immunohistochemistry. In our knowledge, this is believed to be the first confirmed report of co-infection of CDV and T gondii in dog in Korea.

The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.
