Portable microcontroller based measurement unit is demonstrated using digital-to-analog convertor module, analog-to-digital convertor module and additional preamplifier circuit with low-budget but excellent performances. Using the designed measurement unit, the measurement of current below 1 nA with applying voltage up to 5 V is successfully carried out. With the WiFi module in microcontroller, measured data is transferred to the user's computer. To evaluate the performance of the measurement unit, the transfer curve of a commercial N-type field effect transistor was measured with the measurement unit and the results is well consistent with that measured using commercial characterization system.

In this paper, in order to impart the aging condition of the parts, by configuring the cycle of temperature from low temperature was performed by applying the aging conditions for vehicle cockpit module. The reason for the selected modules of the cockpit vehicle parts, because the joint occurrence typical components of the room component is a first module and ceiling cockpit module. After setting the excitation profile using the BSR exciter only that this is for the module degradation after the initial and grasp the change in the dynamic characteristics of the modules based on the before and after deterioration may be made in the module, grasp the noise generating position I measured the noise and proximity. Was also visualized on the position of the joint is generated using a sound camera to objective results occurring where the joint is selected through subjective evaluation.

본 연구에서는 지수의 역으로 정의되는 로그를 학습한 학생들을 대상으로 로그 개념과 성질에 대한 오류를 조사하고, 학생들 스스로 오류를 교정할 수 있도록 역사 발생적 수학 학습 지도 원리에 따른 교수-학습 모듈(module)을 개발하여 수행평가로 적용하고 그 교수학적 효과를 분석하였다. 교수-학습 모듈은 로그에 대한 수학적 분석, 역사발생적 과정에 대한 분석, 학생들의 오류에 대한 심리학적 분석을 바탕으로 로그의 정의와 기본 성질 단원을 중심으로 개발하였다. 교수-학습 모듈의 교수학적 효과는 로그의 뜻과 성질에 대한 사전 사후 지필 평가 결과의 정답률과 오류 발생률을 비교 분석하였다. 구체적으로 유의수준 .05에서 단일표본에 대한 t-검정 결과, 교수-학습 모듈을 적용한 수행평가가 짧은 시간동안 이루어졌음에도 효과가 있는 것으로 나타났다. 그리고 로그의 뜻과 성질 단원에서 나타난 5가지 오류 유형인 '기호나 용어, 개념에 대한 이해 부족으로 인한 오류(E1)', '정리나 성질에 대한 불완전한 이해로 인한 오류(E2)'와 '선행 지식의 부족으로 인한 오류(E3)', '계산 실수로 인한 오류(E4)', '풀이 과정의 중단으로 인한 오류(E5)' 중 교수-학습 모듈을 적용한 결과, E2와 E1 오류가 크게 개선되었다.

This study was to develop the flood analysis module (FAM) for implementation of a web-based real-time agricultural flood management system. The FAM was developed to apply for an individual watershed, including agricultural reservoir. This module calculates the flood inflow hydrograph to the reservoir using effective rainfall by NRCS-CN method and unit hydrograph calculated by Clark, SCS, and Nakayasu synthetic unit hydrograph methods, and then perform the reservoir routing by modified Puls method. It was programmed to consider the automatic reservoir operation method (AutoROM) based on flood control water level of reservoir. For a $15.7km^2$ Gyeryong watershed including $472{\times}10^4m^3$ agricultural reservoir, rainfall loss, rainfall excess, peak inflow, total inflow, maximum discharge, and maximum water level for each duration time were compared between the FAM and HEC-HMS (applied SCS and Clark unit hydrograph methods). The FAM results showed entirely consistent for all components with simulated results by HEC-HMS. It means that the applied methods to the FAM were implemented properly.

현대의 물류는 파렛트를 활용한 일관운송체계로 변화하고 있다. 더불어 포장용기의 적재율과 타 수송수단과의 정합성을 높이려는 노력도 병행되고 있다. 이와 같은 일련의 추세는 물류의 효율화를 통한 물류비 절감이라는 명제에 기반을 둔다. 파렛트를 이용한 일관수송에서 기본이 되는 것은 포장의 단위이다. 개별 포장의 크기와 형태가 포장용기의 적재율을 최대화시키도록 하는 것이 관건이기 때문이다. 또한 포장용기는 이차적으로 수송수단의 적재함이나 보관시설 등 연관된 물류활용에 영향을 미치기 때문에 포장의 단위가 미치는 파급의 범위는 넓다. 본 연구의 목적은 포장모듈 표준화 사업의 효과를 평가하는 척도(MOE)를 선정하고 이를 반영한 평가모형을 개발하는데 있다. 선행연구의 사례와 타 학문분야의 계량화 방법 등을 토대로 포장모듈의 표준화가 물류산업에 미치는 영향을 파악하고 이를 계량화하는 방안을 제시한다. 연구의 방법론적 측면에서 볼 때 물류활동 부문별로 나타나는 포장모듈 표준화의 효과를 어떠한 방법으로 계량화하고 가중치를 두어 하나의 대표값으로 추출하느냐가 관건이 된다.

The base station (BS) in the CDMA Mobile System (CMS) connects calls through the radio interface and is designed to provide mobile subscribers with high quality service in spite of mobile subscribers motions. The BS consists of multiple base station transceiver subsystems (BTSs), a base station controller (BSC) and a base station manager (BSM). This paper is concerned with the BSC and the BSM. The BSC is located between the BTSs and the mobile switching center (MSC) connected with the public network, and to mobile subscribers via the BTSs. The BSM provides operator-interfaces per the BS and takes responsibility of operation and maintenance (OAM) of the BS. Design of the BSC is based on two module types: functional module and unit module. The functional module is used to support new services easily and the unit module to increase the system capacity economically. Both modular types are easily achieved by inserting the corresponding modules to the system. Particularly, in order to efficiently support the soft handover which is one of CDMA superior advantages, the BSC adopts a large high-speed Packet switch connecting up to 512 BTSs, and thus mobile subscribers can be provided with soft handover in high probability. The BSM is based on a commercial workstation to support OAM functions efficiently and guarantee high reliability of the functions. The BSM uses graphical user interface (GUI) for efficient OAM functions of the BS.

Purpose: This study aims to establish detailed spatial planning by identifying the needs for a seclusion module for emergency psychiatric patients. Methods: The necessity of medical space with seclusion function was analyzed from spatial, medical, and social perspectives. The needs for a space capable of performing three medical functions: protection, isolation, and treatment, was analyzed. Among various types of mobile medical facilities, seclusion space was considered suitable for utilizing modular construction methods, as it is the most rational method that can satisfy the environmental level of fixed healthcare facilities' space. Therefore, seclusion modules based on modular construction were planned, consisting of two protective units for stabilizing patients with psychiatric illness, one for treatment unit that can accommodate both internal and external treatment, and another one for an infectious disease isolation unit equipped with negative pressure equipment. Implications: This study analyzed the necessary medical functions of the interior space of the mobile stabilization module based on the spatial analysis of existing medical facilities, and proposed alternative spatial configurations according to treatment, seclusion, isolation functions.

JTAG 기반 SoC의 디버깅 성능향상을 위한 온 칩 디버깅 유닛(On-chip debugging unit)을 제안하였다. 제안된 디버깅 유닛은 JTAG 모듈, 코어브레이커로 구성된다. JTAG 모듈은 기존의 IEEE 1149.1 표준을 변형하여 효율적으로 설계하였다. SoC 시스템의 집적도가 높아질수록 1회의 디버깅 사이클을 실행하기 위한 반복적인 TAP 명령의 인가가 예상된다. 제안된 디버깅 유닛이 TAP 명령 인가과정의 불필요한 클럭 소모를 최소화하였다. 성능분석 결과 기존의 방식과 비교하여 14% 정도의 디버깅 성능의 증가를 보였고 TAP 컨트롤러 회로의 게이트 수는 50% 정도 감소하였다.

A new design technique of fabricating 40 GHz up-converter modules for digital microwave radios has been developed. The design of the up-converter module is based on unit circuit blocks, which are to be characterized using a special test fixture. The complete module design may be as simple as a cascade layout of these unit circuit blocks. Also, the 40 GHz up-converter module employs a new microstrip-to-waveguide transition and a tapped edge-coupled filter, which are less sensitive to fabrication tolerances.
