최근 유비쿼터스가 최대의 화두로 떠오르고 있다. 새로운 지식 정보와 경쟁력 강화를 위한 유비쿼터스 컴퓨팅 혁명은 기술 활용 체제라는 새로운 패러다임 전환과 이에 따른 대대적 변화를 예고하고 있다. 또한, u-러닝 기반여건과 학습 장애상황들을 극복하기 위해서는 기술 공학적으로 상당히 접근되어 있는 시스템과 생활 지도 측면의 검사가 반드시 필요하다. 본 논문에서는 OSGi(Open Service Gateway Initiative)에 기반을 둔 USB (Universal Serial Bus) 단말기 시스템을 이용하여 초등학교에서 증가 추세이며 반드시 해결해야 할 주의력 결핍 및 과잉장애(Attention Deficit Hyperactivity Disorder, 이하 ADHD)에 대한 간편검사를 구현하였다. OSGi 기반 USB 단말기 시스템은 다수의 USB 단말기들과 OSGi를 탑재한 서버가 고속의 USB 버스를 이용하여 네트워크를 구축한 다양한 유비쿼터스 시스템으로 정보의 보호, 네트워크의 안전성, 비용 절감 및 유지 보수가 용이함, 주의 집중력 향상 등의 장점이 있고, ADHD는 조기 진단과 치료가 절실하기 때문에 본 논문에서 다루게 되었다. OSGi 기반 USB 단말기 시스템을 활용한 ADHD 간편검사를 통하여 지필 검사의 단점을 보완하고 컴퓨터를 이용한 검사의 문제점을 해결할 수 있었으며, 학생 지도에 도움을 줄 수 있는 시스템 적용을 확인하였다. 본 논문 결과에 비추어 학교에서 공식적으로 실시하는 인성검사나 지능검사와 일반 시험문제 풀이 그리고 수준별 학습용 시스템, 맞춤형 설문 조사 프로그램, 장애인을 위한 학습 시스템, 다수가 같이 하는 게임시스템으로도 사용이 가능하다. Recently, the ubiquitous is handled by maximum topic. New knowledge information and ubiquitous computing evolution have promoted new paradigm transfer and grand change. Also, need technology as powerful engineering approached fairly system and educational guidance side examination necessarily to overcome u-Learning base situation and studying obstacle situations. This treatise embodied handiness examination about attention shortage and excess obstacle (Attention Deficit Hyperactivity Disorder, low ADHD) who must solve so as to be square and level being increase trend in primary school using USB (Universal Serial Bus) terminal system that allow fetters to OSGi (Open Service Gateway Initiative). That OSGi base USB terminal system is easy preservation of information, safety of network, cost-cutting and maintenance by various ubiquitous system that server that load many USB terminals and OSGi uses an USB bus of high speed and construct network, there is advantage of concentration elevation and so on of week and ADHD handled in this treatise because early diagnosis and treatment are serious. The confirmed system application that can supplement paper and pens examination's shortcoming and could solve examination's problem which use computer, and help in student guidance through ADHD simpleexamination who utilize OSGi base USB terminal system. Is available by game system that system for human nature examination or intelligence test and general exam explaining and level studying, order style question investigation program, studying system for disabled person, majority that enforce in public in school this study finding does together.

도어락 스위치(Door-lock switch)는 드럼세탁기, 식기 세척기 등 회전이나 열이 발생되어 작동 할 때 임의로 열지 못하도록 하는 가전제품에 쓰이는 도어 안전잠금장치로 드럼세탁기에서는 없어서는 안 되는 중요한 부품 중의 하나이다. 드럼 세탁기 도어는 소비자가 사용 할 때 느낌을 가지는 부분으로 항상 안전성과 동시에 감성이 뒤따르는 부품이기도 하다. 본 논문은 드럼세탁기의 도어에 감성과 관련된 요소들을 조사하였으며, 도어락 스위치의 기구적인 구조들을 파악한 뒤 드럼세탁기에 장착하였을 때 열림력, 닫힘력을 측정할 수 있는 지그와 소프트웨어를 제작하고 측정한 힘의 그래프를 분석하여 사용자에 의해 평가한 후, 드럼세탁기 도어락 스위치의 구조에 따른 감성에 차이점 을 찾아보고 시스템의 사용을 검증하였다. The door-lock switch is one of the most important part in the front-load washer. As an safety system, it keeps the door locked while the front-load washer or the dish washer is working and generating heat and spin. The door of front-load washer needs the emotionality as well as the safety because the consumers always get feels when using it. In this paper, We study about emotional factors in the door of front-load washer and analyze the difference of emotionality as the structure of the door-lock switch changed. For this, we analyze the force graph by using the software and the jig which can measure the force while the door is opened or closed.

This study was conducted as part of the purpose of realizing the fuelization and quality improvement using spent mushroom substrate through a torrefaction pretreatment. Conditions of torrefaction pretreatment were performed at temperatures of 250, 350, and 450°C and reaction times of 600, 1,200, and 1,800s, respectively. In order to confirm the fuel characteristics were conducted to proximate analysis and higher heating value. As the experimental materials, to determine the tendency of spent mushroom substrate according to the cultivation period of Letinula edodes, the products discarded after harvesting 2, 4, 6 and 8 cycles were used. As a result, higher heating value and content of fixed carbon has been increased and contents of moisture content and ash has been decreased the more torrefaction pretreatment for temperature and time increased. Furthermore, the results of calculating the energy yield through the higher heating value and the mass yield, it found that most suitable for molded charcoal of the manufacturing a conditions of 1,200-1,800s of 350°C in this study.

N/A Background/Aims: Parenteral exposure, such as transfusion, drug abuse, needle stick injury, tatooing, hemodialysis and transplantation, is well documented as the major route of transmission. But about half of hepatitis C virus(HCV) carriers have no previous history of parenteral infection. Therefore, other possible routes of the spread should be evaluated. The possibility of intrafomilial transmission of HCV was considered to be low as compared to that of hepatitis B virus(HBV), but recent publications from Japan and Europe elicit the interest in intrafamilial transrmission, especially in spousal transmission. The aim of this study is to investigate the possibility of spousal transmission of HCV. Methods: We analyzed clinical features, serum transaminase and anti-HCV in 56 spouses who got married to anti-HCV positive patients. The mean age in index cases was 44.7 years, 45.6 in male and 43.2 in female and that of spouses was 42.4 yenrs, 45.7 in male and 40.7 in female. The mean duration of marriage was 20,0 years, distributed from 1 to 50. Index cases included 8 asymptomatic carriers, 44 chronic hepatitis, 3 liver cirrhosis and 1 hepatoma. Four of those had previous history of blood transfusion. Results: Among 56 spouses, anti-HCV was detected in 9 cases representing 16.1%. Four of those were clinically asymptomatic carriers and remaining 5 had chronic hepatitis. The mean age in index cases of anti-HCV positive spouses was 56 years old and was older than that of anti-HCV negative spouses 42.6(P<0.01). The mean duration of marriage in index cases of anti-HCV positive spouses was 30,9 years and was longer than that of anti-HCV negative spouses 18.0(P<0.05). Conclusions: This study revealed higher prevalence of anti-HCV in spouses who got married to anti-HCV positive carriers compared to that of general population. As the duration of marriage was getting longer, the frequency of anti-HCV in spouses increased(P<0.01). These results suggest that the spouses of anti-HCV positive carriers could be a high risk group for HCV transmission. (Korean J Gastroenterol 1997; 29:207 - 213)

GPC를 이용한 규칙기반 자기동조 PID제어기에 관한 연구

이창구(Chang-Goo Lee),김성중(Sung-Joong Kim) 대한전자공학회 1992 대한전자공학회 학술대회 Vol.1992 No.10

In this paper, we present a solution to the PID tuning problem by optimizing a GPC(General Predictive Control) criterion. The PID structure is ensured by constraning the parameters to a feasible set defined by the discrete-time Euler approximation of the ideal continuous-time PID controller. The algorithm is extended by incorporating heuristic rules for selection of the significant design parameters. The algorithm has been successfully tested and some results are presented.
