This paper presents development results of integrated operating program and its simulator for an inshore test miner. The inshore test miner drives on the seabed and collects manganese nodules. For operating the test miner, integrated operating program (IOP) is needed for remote control and monitor of the miner in real-time. However, it is hard to develop the practical IOP for the test miner system, because the system is big, expensive, and unique. So a simulator was developed as a test substitute in order to save time and to reduce cost. Using test results of the simulator, the IOP of the test miner was developed. The developed IOP consists of remote program, host program, monitoring program and database program. The operating program was developed using PXI and Labview of NI. The experimental results are presented to show the applicability of the developed program.

This study was designed to develop a website for providing nutrition information and education for college women and young women. The website focuses on two topics ; general nutrition and desirable weight control. This program is located at http : // www.ezydiet.co.kr. This program is composed of 5 major sections. The first two sections were designed to provide information ; one for general nutrition, and the other for providing information regarding weight control. The first section includes information regarding young adult women's diet, nutrition standards, such as the RDA or Korean Food Pyramid, drinking and smoking. The second section coveres information regarding desirable control, foods with high or low calories, eating disorders and popularly used dieting methods. The third section is for simple nutrition assessment, consisting of assessment of ideal body weight and obesity, energy requirements, and eating habits. The fourth section was designed to introduce and help users to apply behavioral modification techniques, such as monitoring, goal setting, stimulus control and reinforcement. The final section was designed for meal planning, by introducing a food exchange list and menu examples for one week. The characteristics of this web-based program are as follows ; 1) provide nutrition information systematically, 2) involve sections for the participation of the user, 3) include food pictures to help understanding of nutrition information, 4) include management modules for some sections to revise or update the information. One-hundred and ten female university students participated in the evaluation of this website. The evaluation results were favorable. About 90% of subjects rated that this program covers major topics 'well ' or 'very well', and that it was 'easy'to 'very easy'to understand the contents on website. Two-thirds of subjects rated quite positively on questions regarding attractiveness, overall quality and technical quality of website. In addition, about three-fourths of subjects answered that this website was helpful in increasing nutrition knowledge and in applying nutrition information into daily life. These results suggested the possibility of using a website as a means of providing nutrition information and education for young adult women.

Development of Real-Time Quality Evaluation of Friction Welding by Acousitc Emission : Report 1 ABSTRACT : According as the friction welding has been increasingly applied in manufacturing various machine components because of its significant economic and technical advantages, one of the important concerns is the reliable quality monitoring method for a good weld quality with both joint strength and toughness in the process of its production. However no reliable nondestructive test method is available at present to determine the weld quality particularly in process of production. So this paper presents an experimental examination and quantitative analysis for the real-time evaluation of friction weld quality by acoustic emission, as a new approach which attempts finally to develop an on-line quality monitoring system design for friction welds using AE techniques. As one of the important results, it was confirmed, through this study, that AE techniques can be reliably applied to evaluating the friction weld qualify with 100% joint strength, as the cumulative AE counts occurring during welding period were quantitatively correlated with reliability at 95% confidence level to the joint strength of welds. Real-Time Evaluation of Automatic Production Quality Control for Friction Welding Machine : Report 2 Abstract : Both in-process quality control and high reliability of the weld is one of the major concerns in applying friction welding to the economical and qualified mass-production. No reliable nondestructive monitoring method is available at present to determine the real-time evaluation of automatic production quality control for friction welding machine. This paper, so that, presents the experimental examinations and statistical quantitative analysis of the correlation between the initial cumulative counts of acoustic emission(AE) occurring during plastic deformation period of the welding and the tensile strength of the welded joints as well as the various welding variables, as a new approach which attempts finally to develop an on-line (or real-time) quality monitoring system and a program for the process of real-time friction welding quality evaluation by initial AE cumulative counts. As one of the important results, it was well confirmed that the initial AE cumulative counts were quantitatively and cubically correlated with reliability of 95% confidence level to the joint strength of the welds, bar-to-bar (SCM4 to SUM31, SCM4 to SUM24L) and that an AE technique using initial AE counts can be reliably applied to real-time strength evaluation of the welded joints, and that such a program of the system was well developed resulting in practical possibility of real-time quality control more than 100% joint efficiency showing good weld with no micro-structural defects.

The purpose of this study is to examine to control of glucose level and the occurrence of chronic complications of diabetes by compliance groups with health care regimen The subjects were consisted of 300 out patients with type 2 diabetes mellitus from beginning of March through the end of April in 2001, who visited at the endocrinology department at Kangnam St. Mary's Hospital of Catholic University in Seoul. The patient's compliance level with health care regimen was assessed at questionnaire. However, the blood glucose level and the occurrence of chronic complications of diabetes were assessed at medical record review. The data were analyzed by SAS program for chi square test and t-test. The results were as follows. 1. Significant differences were found among the factors such as duration of diabetes, the number of participation of diabetes educational program, job, smoking, self monitoring of blood glucose and the methods of diabetes therapy between high and low compliance groups. High compliance group patients had a diabetes longer than low compliance group patients. High compliance group patients more frequently attended the educational program and checked themselves monitoring blood glucose than low compliance group patients. Also, they did not work recently, smoked less and got more insulin injection therapy compared to low compliance group patients. 2. No significant differences were found among the result of fasting blood glucose. 2-hour postprandial blood glucose, and $HbA_{l}c}$ between high and low compliance groups. 3. The occurrence rate of macrovascular complications of chronic complications of diabetes were lower, however, the occurrence rate of microvascular complications were higher in high compliance group than in low compliance group with health care regimen.

TPLMS programs in four large rivers have been developed to improve the water quality from possible pollutants originated from watershed areas. The success of TPLMS program is depended on nonpoint source control. Currently, the pollutant loading from nonpoint pollution sources is gradually increasing as developing the nearby watershed. However, there are not enough data concerning on nonpoint pollution in Korea because of lacking of monitoring activities. It is the main reason of uncertainty. Therefore, this manuscript will summarize the EMCs in various landuses based on monitoring program. Also the EMC in each paved area will be compared and discussed to find the differences. When the EMC is compared by average monitored sample concentrations, the EMC values are 2-4 times higher than sample concentrations. It means the monitoring program is very important in the field of nonpoint pollution. The pollutant loadings from bridge landuse is higher than loadings from parking lot and highway because of more traffic activities.

Our country has a convoluted coastline and the marine weather fluctuates locally, so it needs effective AtoN operation for the safe navigation of vessels and fishing boats sailing the coast. Especially, large beacon must ensure the safety of the vessels and always lit at night. If large beacons installed in the lighthouse are not lit, vessels can not assure their location. Thus the accidents is likely to occur, which can cause great economic damage. In this paper, we developed a monitoring system of large beacon to monitor and control the status of information. This system was designed for a special purpose of taking precautions against possible accidents on the sea.
