The most widely used nonlinear analog cells are multipliers and dividers. Four-quadrant multipliers have been reported by using variable-transconductance and quarter-square approaches. But they are not reconfigurable to achieve different function such as divider. In this paper, analog four-quadrant multiplier/divider is proposed using operational amplifier and V-Ⅰ converters. The designed multiplier/divider circuits can be reconfigurable in order to perform the different function. The multiplier linear ranges are between -2V and +2V, and nonlinear error is measured 0.87% by SPICE simulation.

고등학교 한국지리의 식생,임업 단원 내용 분석

최영미,공우석 한국지리환경교육학회 2001 한국지리환경교육학회지 Vol.9 No.1

이 연구는 한국지리 교과서 기술 내용의 문제점을 보다 구체적으로 제시하기 위해 식생과 임업소단원을 사례로 분석되었다. 제1차에서 제6차 교육과정까지의 식생·임업 단원 내용 변화를 각 교육과정별 교과서 중 1종씩 택해서 살펴보았고, 삼림대 구분의 변천이나 내용 기술의 문제점을 기존 연구 결과와 비교·검토하여 다음과 같은 사실들을 알 수 있었다. 삼림대를 제5차까지는 아한대림, 온대림, 난대림으로, 제6차에서는 냉대림, 온대림, 난대림으로, 농업 교과서에서는 한대림, 온대림, 난대림으로 구분하여 혼란스럽다. 즉 이러한 구분이 식생구분인지 기후구분인지 분명하지 않으므로 보다 명확한 구분이 필요하다. 대표수종에 있어서도 각 교과서마다 다르고 임업 단원에서도 다르게 제시되어 있다. 또한, 제6차 교육과정 시기의 12종 교과서 모두 삼림대 구분과 농작물 북한계선에 관한 지도자료를 제시하고 있으나 각 교과서마다 구분지표가 다르거나 잘못된 정보의 수록으로 혼란이 야기되었다. 따라서, 교육현장에서의 혼란을 줄이기 위해서는 정확한 식생 정보에 의한 일관된 자료제시가 요구된다. This work aims to understand the problems of content and description in the High Korean Geography Textbooks, with special reference to the chapters of Korean vegetation and forestry. Each textbook from 1st to 6th curriculums has selected to examine the changes in contents of the vegetation and forestry chapters. The results and suggestions obtained are as follow. Vegetation zone had been divided into cool temperate, temperate, and warm temperate forests until 5th curriculum. And then, in 6th curriculum, it was divided into cold, temperate, and warm temperate forests. In agriculture textbooks of the same curriculum period, however, forest has divided into arctic, temperate and warm temperate forests. Twelve geography textbooks in 6th curriculum period still suggest different vegetation zone and geographical ranges of plants with economic value, and often include the wrong information. Concerning the typical tree species of each forest zone, each textbook still suggests different examples. Therefore, confusions on the forest division and species range are still remains. To avoid such confusion in the forest zonations, climate and vegetation zonations need to be differentiated. Overall, materials from accurate vegetation informations need to be provided more consistently to avoid further confusion.

Biometric encryption refers to a process of secure key management. Biometric encryption does not directly provide a mechanism for the encryption/decryption of data, but rather provides a replacement to typical passcode key-protection protocols. Although the process of biometric encryption can be applied to any biometric image, the initial implementation was achieved using fingerprint images.

능동 클램프 ZVS 플라이백 컨버터의 역률개선에 관한 연구

본 논문에서는 single-stage, two-stage 두가지 역률보상(PFC)기법을 기존의 능동 클램프 플라이백 컨버터에 적용하여 역률 개선을 하였다. 삽입된 플라이백 컨버터의 능동클램프회로가 주스위치와 보조스위치의 영전압스위칭(ZVS)을 구현하며, 스위칭 손실을 줄임으로써 고효율을 얻을 수 있고, 높은 주파수에서의 스위칭이 가능하다. 하지만 일반적으로 사용되는 다이오드정류기, 평활용커패시터에 의한 낮은 역률의 문제점이 남아있다. 본 논문에서는 300W급 능동 클램프ZVS플라이백 컨버터를 설계하여 single-stage, two-stage방식을 적용, 입력역률개선을 시뮬레이션과 실험에 의해 입증하고자 한다. This paper analyzed PFC of active clamp ZVS flyback converter by adding two method PFC (Power Factor Correction) circuit - two-stage and single-stage. The addition of active clamp circuit also provide a mechanism for achieving ZVS of both the primary and auxiliary switches. ZVS also limits the turn off di/dt of the output rectifier, reducing rectifier switching loss and switching noise, due to diode reverse recovery. As a results, the proposed converters have characteristics of the reduced switching noise and high efficiency in comparison to conventional flyback converter. The simulation and experimental results show that the proposed converters improve the input PF of 300W ZVS flyback converter by adding single-stage, two-stage PFC circuit.

Objectives : The purpose of this study was to evaluate the reliability of questionnaire according to item arrangement on patient satisfaction questionnaire. Methods : We developed the two types of questionnaire with different item arrangement. In the first type (A), questions were arranged according to medical service dimensions. Questions in the second type (B) were arranged according to medical process. Both questionnaires were composed of six dimensions: physical environments, process, competence, courtesy, information giving, understanding patients. Measurements were performed on a 5-score Likert scale. In an outpatients and inpatient survey, total 777 patients answered the type A (outpatients: 257, inpatients: 128) or Type B (outpatients: 257, inpatients: 135). In order to compare the internal consistency of two types. Cronbach's α were calculated. Multiple regression analysis was also performed to know which type of questionnaire explain more of the overall satisfaction. Results : In outpatient survey, type A questionnaire showed higher internal consistency than B except physical environments dimension. Also in inpatient survey, type A had higer internal consistency than B in four dimensions(process, competence, courtesy, understanding patients). In the results of multiple regression analysis, type A questionnaire (R² =0.53) explained more of the variation in overall satisfaction then B questionnaire (R2=0.43) in outpatient survey. In inpatient survey, type B questionnaire (R²=0.40) explained, more of the variation in overall satisfaction than type A questionnaire (R² =0.33).But the.difference of R was not significant in inpatient survey. Conclusion : The results of this study support that type A questionnaire has higer reliability in assessment of consumer satisfaction than type B.

We numerically investigate stable propagation regimes of 10 ㎓ train of optical solitons with 17.6 ps widths to determine the acceptable variations of periodic amplifier gain(△G), dispersion(△D), and initial chirp(C), as a function of the amplification period LP. We fine that, when LP = 25 km, the acceptable variations are △G = ±4%, △D= ±12%, and C= -0.36 ∼ 0.39. The variations decrease as the amplification period LP increases.

This study was performed to characterize the seasonal fluctuation of water quality and sediment environment from April, 2001 to November, 2001 in Gamak bay. Which was a productive area, but recently its fisheries conditional have been deteriorated because of increasing waste-water from municipal area, industry and autochthonous pollution by farm industry. In the survey of seawater quality, DO and COD concentrations were lowest in bottom layer at summer, but DIN and DIP contents were higher than those in surface layer. Eutrophication indices mean that eutrophication area move from south to north entrance via northern-west inner area with seasonal change from summer to autumn. In the survey of sediment environment, ignition loss(IL), chemical oxygen demand(COD), DIN and Dip were in the range of 3.8~15.7%, 10.3~60.6mg/g-dry, 5.053~1.810mg/ℓ and 0.065~0.324mg/ℓ , respectively. COD in sediment were highest at winter and spring. And, they were higher than sediment standard in the south inner area, which mean heavily polluted conditions with organic constituents.
