본 연구는 지방지역에서 주간선도로 및 보조 간선도로의 기능을 수행하도록 규정된 일반국도의 수행기능을 통계적 방법으로 유형화하고, 각 유형별 교통특성 규명에 의한 일반국도의 적정 설계기준을 제안하였다. 전국의 도로망에서 일반국도가 수행하는 기능은 크게 3가지로 유형화할 수 있음을 통계적 방법으로 검증하였으며, 각 유형별 도로 구간의 교통특성 조사 결과, 당초 간선도로로 건설된 일반국도가 그 역할을 충분하게 수행하지 못하는 것으로 판단할 수 있었다. 이러한 문제점의 개선 대안으로 일반국도가 간선도로로서의 역할을 수행할 수 있도록 기능별 설계기준의 차별화와, 목표통행속도 개념을 반영한 부속시설 정비 기준을 제안하였다.

In response to the development of IT technology in the 21st century and the advancement of the public human rights consciousness, it has become necessary to continuously evolve the office environments to support the changes of organizational structure and work methods of the police investigation departments. As a facility standard, continuous researches on standardized design space models and guidelines of the police investigation departments are needed. In respond to the organizational changes for the convenience of the working police investigators and the protection of the human rights of the visiting public, the environmental improvement projects for the office of the investigation department of the police stations are going on since 2014. In this study, analyzation and verification of the 3 cases of pilot projects for the improvement of police investigation departments would be done, based on the policy research project in 2014: 'the standard design direction of police officers for the protection of human rights and benefit of police investigation process.' The purpose of this study is, first of all, the actual situation survey for presenting the standard design space model and guidelines of investigation department of the police department. Secondly, the validation of the spatial model adequacy for for the past 3 years' case study of the police investigation department's environmental improvements by the application of standardized design space models and guidelines.

Modem technology depends on the reliability of extremely high technology equipments. In the production of semiconductor wafer, optical and electron microscopes, ion-beam, laser device must maintain their alignments within a sub-micrometer. This equipment requires a vibration free environment to provide its proper function. Especially, lithography and inspection devices, which have sub-nanometer class high accuracy and resolution, have come to necessity for producing more improved giga and tera class semiconductor wafers. This high technology equipments require very strict environmental vibration standard, vibration criteria, in proportion to the accuracy of the manufacturing, inspecting devices. The vibration criteria of high sensitive equipment should be represented in the form of 'exactness' and 'accuracy', because this is used as basic data for the design of building structure and structural dynamics of equipment. This paper deals with the properties of time and frequency domain in order to obtain more improved vibration criteria for high sensitive equipment.

The article presents a concept of designing a Multiplexer circuit which acts as a "Selector" and that becomes capable to select different speed created at different TTL Gate configurations; Standard TTL(Normal Speed), High Speed TTL(High Speed), Schottky TTL(Super High Speed) and further connect the selected Gate speed to the CAR shape created using C-Programming at Computer Graphics and finally CAR shape display at different speed to the color TV. The Multiplexer supporting efficient and more reliable selection criteria using "Logical based selection criteria" and further the output from multiplexer is provided to CAR shape created using c-programming and finally CAR shape is display to color TV system. Basic purposes and assumptions regarding the design and development of this system as well as a description of its operation have been presented.

This study provides standardized scientific criteria for education materials on nutrition and diet that could be used in schools, workplaces, and health and medical facilities. The study was conducted from April 2011 to October 2011. Literature reviews, institutional visits, and telephone interviews were conducted for the first draft of the accreditation criteria. Expert meeting and advisory councils were conducted in order to obtain feedback after development of the first draft of accreditation criteria. In order to verify the validity and reliability of the first draft on certification criteria, a survey was sent out to 143 professionals, including professors, researchers, health and medical experts, teachers, nutrition teachers, dietitians, and clinical nutritionists. After several modifications, the final accreditation criteria were established for 1) printed materials (authority, credibility, objectivity, organization, editing, real-life usability, activities and participation, and public interest), 2) web-sites (authority, credibility, objectivity, design, real-life usability, accessibility, currency, and public interest) and 3) materials with activities (credibility, organization, design, convenience of utilizing, safety, and public interest). Out of several criteria, contents (authority, credibility. and objectivity) and publicity (public interest) areas are mandatory requirements. For the accreditation, books for learning and materials with activities are required to meet more than six evaluation components, and the other materials are required to meet more than five evaluation components, including the required area. Accreditation criteria developed in this study could be used as a standard for development or selection of good education materials for nutrition and dietary life.

This work presents an optimality criteria method applicable io the design of plane frames with I-shape sections. All kinds of constraints are treated properly to ensure the mathematical rigour of the method as ever. Among the various properties of a section, the cross-sectional area is chosen as the design variable associated with the member. Then other properties, moment of inertia and depth, are determined from the cross-sectional area using relationships established in advance from the sectional data for AISC standard W shapes. The optimality criteria established in this work is perfect in mathematical terms provided that the relationships between properties of a section are correct. A redesign algorithm is derived relying heavily on the Newton-Raphson method to solve the system of nonlinear constraint equations. A worked example is also Presented.

This paper presents, the design of a latch mechanism for wafer containers in a standard mechanical interface environment. For an integrated circuits fabrication factory, the standard mechanical interfaced wafer container is an effective tool to prevent wafers from particle contamination during wafer storage, transporting or transferring. The latch mechanism inside the container door is used to latch and further seal the wafer container for safety and air quality. Kinematic characteristics of the mechanism are established by analyzing the required functions of the mechanisms. Based on these characteristics, a methodology for enumerating feasible latch mechanisms is developed. New mechanisms with one degree-of-freedom and up to five links are generated. An optimum design is also identified with respect to the criteria pertinent to the application. The computer-aided simulation is also built to verify the design.

일상생활 용품에서 최근 지능형 서비스 로봇에 이르기까지 인간의 특성을 직간접적으로 제품 디자인에 활용한 사례를 주변에서 쉽게 찾을 수 있다. 특히 로봇 디자인의 경우는 의인화가 모든 디자인의 출발점이 되기 때문에 외형 디자인뿐만 아니라 사용자와의 인터랙션 디자인에 있어서도 의인화 기법의 활용이 필수적이다. 이러한 의인화 기법의 효과적인 활용을 위해 디자이너가 제품이 의인화된 정도를 측정하고 이를 바탕으로 의인화 기법의 활용도를 평가해야할 필요성이 생겨났다. 본 연구는 지능형 로봇의 디자인을 중심으로 한 의인화 기법 적용 사례 분석 및 의인화 정도를 측정하는 실험을 근거로 하여 의인화 기법의 활용 평가 기준을 수립하는 데 목표를 두었다. 이미지 카드를 활용한 로봇 외형의 의인화 정도 및 표정변화를 통한 로봇 인터랙션의 의인화 정도를 평가하는 실험을 통해서 의인화 기법의 활용도는 '형태의 의인화', '인터랙션의 의인화', '형태와 인터랙션의 의인화 조화 정도' 에 의해 평가할 수 있다는 결과를 얻었다. 본 평가 기준을 로봇 디자인 과정의 하나의 평가 방법으로 활용하면 로봇에 대한 사용자 호감도 증가 및 사용법이 복잡한 로봇 제품을 쉽고 직관적이게 접하게 만드는 효과를 기대할 수 있을 것이다.

본 연구에서는 미국 NFPA 204 기준에 의해 설계된 수직 배연구에 대하여 배연구의 위치, 외기 온도, 풍속 및 화재크기가 자연배연 성능에 미치는 영향과 화재특성을 CFAST 프로그램을 사용하여 수치 해석적으로 조사하였다. 배연구는 외벽의 최고 상부에 위치한 경우와 외기온도가 낮은 경우 및 풍속이 작은 경우 배연성능기준을 만족하였다. 또 화재크기가 클수록 배출량은 증가하나 연기층 높이는 낮아져 배연성능기준을 만족하지 못하였다. 직접 외기와 통하는 수직 자연배연구의 설계시 해당지역의 최고 온도와 최대 풍속을 고려하고, 설계화재를 정확히 결정하여 배연성능기준이 만족되도록 주의가 요망된다.
