Knowledge regarding lipid catabolism has been of great interest in the field of animal sciences. In the livestock industry, excess fat accretion in meat is costly to the producer and undesirable to the consumer. However, intramuscular fat (marbling) is desirable to enhance carcass and product quality. The manipulation of lipid content to meet the goals of animal production requires an understanding of the detailed mechanisms of lipid catabolism to help meticulously design nutritional, pharmacological, and physiological approaches to regulate fat accretion. The concept of a basic system of lipases and their co-regulators has been identified. The major lipases cleave triacylglycerol (TAG) stored in lipid droplets in a sequential manner. In adipose tissue, adipose triglyceride lipase (ATGL) performs the first and rate-limiting step of TAG breakdown through hydrolysis at the sn-1 position of TAG to release a non-esterified fatty acid (NEFA) and diacylglycerol (DAG). Subsequently, cleavage of DAG occurs via the rate-limiting enzyme hormone-sensitive lipase (HSL) for DAG catabolism, which is followed by monoglyceride lipase (MGL) for monoacylglycerol (MAG) hydrolysis. Recent identification of the co-activator (Comparative Gene Identification-58) and inhibitor [G(0)/G(1) Switch Gene 2] of ATGL have helped elucidate this important initial step of TAG breakdown, while also generating more questions. Additionally, the roles of these lipolysis-related enzymes in muscle, liver and skin tissue have also been found to be of great importance for the investigation of systemic lipolytic regulation.

Objectives Childhood trauma increases substantial risks for later developing not only mental health issues including psychotic illnesses such as schizophrenia but also physical illness. In this study, possible associations of childhood trauma with metabolic syndrome and physical heath indices were tested among outpatients with schizophrenia. Methods A final sample of 46 adult outpatients with schizophrenia was recruited from an outpatient psychiatric unit of Hanyang University Guri Hospital. Participants completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), laboratory tests and physical measurement including Body Mass Index (BMI) and Waist to hip ratio (WHR). The Clinical Global Impression (CGI) scale and the Global Assessment of Functioning scale (GAF) were also administered. Results We did not find significant correlations between total scores of childhood trauma and any of these variables, but physical neglect was negatively associated with BMI (r = -0.329, p = 0.026) and waist circumference (r = -0.304, p = 0.040). Conclusions In this preliminary study, we noted that subtypes of childhood trauma could contribute to physical health status separately. Clinicians need to consider the possibility that childhood trauma may affect physical health as well as psychological aspect of schizophrenic illness.

An electronic micropayment system, one of electronic payment systems, is suitable especially when a small amount of money is to be paid frequently in order to purchase on-line goods (i.e. database search, software distribution, electronic news service, etc). In addition, since the amount of payment is small, possible damages caused by system failures are lower than other payment system. In this paper, a micropayment protocol in electronic commerce environments on the Internet is proposed, based on the PayWord system. And a micropayment electronic commerce system which executes the protocol proposed is implemented. Unlike the PayWord system, however, the micropayment protocol proposed in this paper is designed in such a way that a merchant does not need to request a payment at the end of every business day since a customer cannot purchase goods beyond length of hash chains, which is specified on a certificate. In addition, the system is able to check the validity as well as the duplicate spending of hash chains. The electronic micropayment system with the proposed protocol is consists of Customers, Merchants, and Brokers. Customers are implemented on Windows NT 4.0 using VC++. Merchants are implemented on Solaris 2.5.1 and gcc 2.8.0 using Netscape Web Server and CGI Methods. HP UX 10.20 is used for Brokers.

We implement the PBSM (Protocol-Based Security Module) system which guarantees the secure data transmission under web circumstances. There are two modules to implement for the PBSM architecture. One is Web Server Security Module (WSSM) which is working on a web server, the other is the Winsock Client Security Module (WSCSM) which is working on a client. The WSCSM security module decrypts the encrypted HTML document that is received from the security web server The decrypted HTML document is displayed on the screen of a client. The WSSM module contains the encryption part for HTML file and the decryption part for CGI (Common Gateway Interface). We also implement the proposed idea at the web system.

In this paper, we present a new method for the monitoring of Electric Control Unit's(ECU) self-diagnostic and the sensor signals of vehicle through Web. In order to measure the ECU's self-diagnostic and sensor signals, the interfaced circuit is designed to communicate ECU and terminal according to the ISO, SAE regulation of communication protocol standard. Microprocessor 80C196KC is used for communicating ECU's self-diagnostic signals and the results are sent to the Embedded Linux System(ELS) through RF module. ELS is developed by SA1110, RF module, Embedded Linux. All commands related in ECU communication are executed through Web. The CGI program composed in web server is executed by user and will return sensor signals from ECU Software on Embedded Linux system is developed to monitor the ECU's sensor signals using the arm compiler tool chain in which RS232 port is programmed by half duplex method. The possibility for remote measurement of ECU sensor signal through Web is verified through the developed systems and algorithms.

Genotyping Tool for Viral SEQuences (GTVseq) provides scientists with the genotype information on the viral genome sequences including HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2, poliovirus, enterovirus, flavivirus, Hantavirus, and rotavirus. GTVseq produces alternative and additive genotype information for the query viral sequences based on two different, but related, scoring methods. The genotype information produced is reported in a graphical manner for the reference genotype matches and each graphical output is linked to the detailed sequence alignments between the query and the matched reference sequences. GTVseq also reports the potential 'repeats' and/or 'recombination' sequence region in a separated window. GTVseq does not replace completely other well-known genotyping tools such as NCBI's virus sequence genotyping tool (http://www.ncbi. nlm.nih.gov/projects/genotyping/formpage.cgi), but provides additional information useful in the confirmation or for further investigation of the genotype(s) for the newly isolated viral sequences.

ASP는 동적인 대화형 웹 서버 응용 프로그램을 작성하고 실행하기 위해 사용할 수 있는 '서버 측 스크립트' 환경이다. ASP를 사용하면 HTML 페이지와 스크립트 명령 및 ActiveX 구성요소를 조합하여 대화형 웹 페이지나 강력한 웹 기반의 응용 프로그램을 만들 수 있다. 사용자가 HTML에 익숙한 사람이라면 ASP 스크립트가 동적인 페이지의 작성을 위한 좋은 방법임을 알 수 있을 것이다. 또한 HTML 파일 작성에 필요한 자바 스크립트나 비쥬얼 베이직 스크립트는 물론이고 그 외 HTML 파일의 내용을 요구에 맞게 배치하기 위해 사용하는 CSS1의 기본적인 내용 정도는 알고 있어야 한다고 본다. 뿐만 아니라 CGI 프로그래밍과 웹 서버와 클라이언트의 상호 작용 관계, 그리고 웹 서버 관리하는 방법 등의 내용을 완벽하게 갖추고 있다고는 생각하지는 않는다. 하지만 앞으로 진행해 나가면서 직접 설명을 하지는 않겠지만 이와 같은 기술들이 모두 사용이 될 것이고, ASP는 다른 웹 애플리케이션 언어보다 쉽고, 웹에서의 많은 응용과, 무한한 가능성을 내포하고 있다는 것을 말하고 싶다. 그러므로 ASP에 접근하는 방법에 있어서 운영하는 방법을 연구하였다.

Most of existing expert systems developed for Web use CGI-based techniques and this frequently makes them suffer from the overburden of commercial Web servers, which deal with large-scale services. However, since HTML-based inference technique represents expert's knowledge by hyperlinks among HTML documents, the hypertext function of the Web can perform the inference efficiently in terms of time and space without the help of additional inference engines. In spite of such benefits, when the expert's knowledge is relatively large and/or complicated, the HTML-based inference technique has usually become to have a hard time of dealing with a lot of HTML documents because generation and management tasks of the numerous HTML documents would cause big trouble to the knowledge engineer. To resolve this problem, we developed an automatic generation and management tool for Web-based inference sites, called WeBIS. With this tool, a knowledge engineer can input and edit expert's knowledge using Expert's Diagram on the GUI(Graphical User Interface) environment and automatically generate hyper-linked HTML documents for Web-based inference from the Expert's Diagram.
