Many small systems, utilizing microprocessors, are now being used in various fields. The need for connecting small system is increasing, which locate within a restricted area such as a single bulding, a small cluster of buldings. Utilizing inexpensive microprocessors, we have studied a structure of the multi-loops network system, intra-loop transmission and inter-loop communication schemes. The multi-loop structure, which consists of a number of loops, has been adopted, therefore some loops can be easily added when the number of nodes increases or the traffic rate becomes higher. Each loop is controlled independently, so that trouble of one loop does not effect the other loops. The control is distributed all over the nodes and there is no centrol loop-controller.

Boundary Condition for Bare Chassis Brackets of the Commercial Vehicle

양승복 한국인터넷방송통신학회 2022 Journal of Advanced Smart Convergence Vol.11 No.1

It is common for commercial vehicles to make the top part according to the use after making the bear chassis, and to connect various devices with the bear chassis. Various brackets used in bear chassis for the development of all automobiles, including commercial vehicles, play a role of connecting the components required for driving and operating the car to the car body. In commercial vehicles, components necessary for operation are installed in the bear chassis; that is, the bear chassis of commercial vehicles is a space where the devices required for driving and operating the vehicle are installed. The devices required for the configuration of the vehicle are drive, brake, exhaust and steering, etc. These devices are basically connected to the body, the front axis, or the rear axis. The part interlinking the apparatuses required for the vehicle drive to the car body or axis is bracket. In this study, we analyzed the boundary conditions to evaluate the stability of the three brackets that connect the components of the car to the front axis of the new type of 30-seater bus in the development process. In order to analyze the boundary conditions, the boundary conditions according to the driving condition of the vehicle were classified. For stress analysis to evaluate the stability of brackets according to the driving state of the vehicle, it is reasonable to give the bracket a boundary condition of harsh conditions.

The purpose of this study is to understand the critical role of customers' perceived service justices in relationship marketing. This paper examined the relationships of service justices with relationship quality and student satisfaction, and investigated the effects of relationship quality and satisfaction on student' voluntary behaviors in a social exchange perspective. Data were collected from 190 collage students at a private university located in Taegu, Korea. The empirical results indicated that distributive justice, procedural justice and interactional justice takes strong effect on student satisfaction.

본 연구는 과거 국내 안경 산업의 현황과 취약점을 분석하여 이를 극복하는 방안으로 무선통신 기반의 자동인식기술인 RFID기술을 적용하여 기존과 차별화된 시스템을 구현한다. 안경유통에 적합한 태그와 태그를 인식하는 리더, 리더에서 획득한 물품의 정보를 수집, 처리하는 미들웨어에 대한 소개를 하고, 이들을 통합하여 하나의 시스템으로 구현하여 실제 안경물품에 대한 인식과 인식된 물품의 정보전달 과정을 한눈에 볼 수 있도록 안경물품 Viewer를 구현하였다. 이러한 시스템을 안경유통에 적용하여 재고관리와 실시간 위치정보 제공을 통하여 업무의 효율성 및 극대화, 유통의 투명성을 보장하여 안경 산업 활성화에 적합한 유통관리 시스템을 구현한다. This research analyzes the weaknesses of domestic spectacle industry and applies RFID, which is a wireless-based automated sensering technology, as an alternative scheme. As a first step to explain RFID and apply it to spectacle industry, it presents the middleware that will process compiled information, sensering items along with suitable tags for them, and through inventory controlling and GPS service, it's goal is to achieve an embodiment of integrated system for spectacle industry by maximizing work efficiency.

D대학을 중심으로 한 학생들의 방사선 인식 조사

This survey was willing to suggest the basic data required for strategic planning to improve the recognition rate on radiation by investigating the difference between the college students who major in radiology and who don't about using radiation. As the results of questionnaire survey on 'knowledge, degree of self-consciousness, danger, convenience and management' targeting 441 students who belonged to D college, 75% of them answered that radiation exists in their daily lives and 54% of them answered they did not know about radiation well. It showed that radiation is dangerous no matter how much the amount is (56%) and it is not dangerous if it is managed well (81%). They answered that they enjoy the convenience of radiation (82%) and the use for medical purpose took the highest percentage among them (58%). It showed that it is important to manage the radiation and should be controlled by the government in institutional way than the individual (64%). The negative answer to the question of 'do you trust the government?' was dominant (75% below average). As the results of this survey, it was recognized that both of them who major in radiology or not were aware of positive aspect of radiation (especially medical technology field) well and the improving the perception of radiation led by the government and definite restriction on its safety should be preceded for safe use. 방사선 이용에 대해 대학생 중 방사선 관련 전공자와 비전공자의 인식차이를 파악하여 방사선 인식률 향상의 전략 구상에 필요한 기초자료를 제공하고자 하였다. D대학에 재학중인 441명의 학생을 대상으로 ‘방사선에 대한 지식·자각정도·위험·편익·관리’와 관계된 설문을 한 결과 일상에서도 방사선이 있다는 인식이 75% 였으며, 54%의 학생은 방사선에 대해 잘 알지 못한다고 답했다. 방사선의 위험 측면에서는 적은 양이든 많은 양이든 위험하다(56%) 그리고 관리를 잘 한다면 위험하지 않다(81%)로 나타났다. 또한, 방사선의 이용으로 편익을 추구하고 있다(82%)고 답했으며 이 중 의학적 이용(58%)이 가장 높았다. 이에 방사선 관리가 중요하며 이 관리의 주체는 개인보다 정부의 제도적 통제가 중요하다(64%)고 나타났다. 정부를 신뢰하는가에 대한 질문에는 부정적인 대답(보통이하 75%)이 지배적이었다. 본 연구의 결과 방사선의 전공이나 비전공자들은 모두 방사선에 대해 긍정적인 면(특히, 의료기술분야)을 잘 알고 있었던 것으로 확인되었으며 보다 안전한 활용을 위해선 정부 주도의 국민 방사선지식의 올바른 인식 개선과 방사선안전에 대한 명확한 규제가 선행되어야 하겠다.

It is common to design the duct branches where to supply the required air flow for individual room in residential apartment house. And TAB process is applied to control the designed air volume with adjusting volume dampers and/or supply diffusers after fully installing the ventilation system. These process has been resulted increasing the initial cost for the residential ventilation system because of man-hour and accessories such as volume control damper or diffuser. However it is difficult to adjust the air volume adequately in small air duct branches in residential ventilation system. The purpose of this study is to figure out the performance of distributor with split guide vane for the residential ventilation system. The results of this study are as follows. (1) Air distributor with guide is excellent in controlling and distributing the air volume for the branches (2) Distributing the supply air volume is more accurate when more than 2m long inlet duct connects between OA inlet and distributor. (3) I could be possible to control more accurate when the supply air volume is increased.

In this paper, Using a Fuzzy theory an On-Line phoneme recognition procedure of Korean characters is studied. The recognition method is performed by reading the pixel coordinates, finding the feature points, recognizing the stroke, recognizing the phoneme in order. In the course of recognizing the stroke, first the feature points of an inputed stroke is characterized by starting point, end point, and bending point. and then, based on 0, 5, 6, 7, 8, 9, and 10 stroke code among the recognized stroke the distance or direction between base stroke and the next input stroke is used for recognizing the phoneme
