  • Recently, Korea has established a plan for the supply of hydrogen vehicles and is promoting the expansion of the supply. Risk factors for hydrogen vehicles are hydrogen leakage, jet fire, and explosion. Therefore Safety measures are necessary for this hazard. In addition, risks in semi-closed spaces such as tunnels, underground roads, and underground parking lots should be analyzed. In this study, an explosion experiment was conducted on a hydrogen tank used in a hydrogen vehicle to analyze the risk of a hydrogen vehicle explosion accident that may occur in a semi-closed space. As results, the effect on the structure and the human body was analyzed using the overpressure and impulse values for each distance generated during the explosion.

  • Nowadays Korean governments use Information Technology to improve the quality of life for a people. One of these tries is building the Food Tracing System based on Information Technology. Koreans have big concern about food that is good for health. The Food Tracing System means that the system can follows, traces, and records every steps of production and delivery of food and its ingredient. And this process should be identified and grouped by using tags, marks, and other methods. For example, producer of ingredient, processing steps of food, delivered place could be traced. In addition to food, medical herbs need consumer's trust in production and delivery. To trace and prosecute contaminated medical herbs, medical herbs also need this kind of Tracing System based on Information Technology. This study shows current medical herbs tracing ways and RFID(Radio Frequency IDentification) technology trend. As preceding study for future RFID based medical herbs tracing system, this study suggests the building plan and scenario of the Medical Herbs Tracing System. The determination of the main body for sticking RFID Tags is very important to design for RFID Traceability System. In this study, the starting point of information to medical herbs is an inspection agency. The Medical Herbs to product domestically or import moved to an inspection agency. An inspection agency bond the RFID Tags to packing of the Medical Herbs after examining the a basic its component. At the same time inspector give the information of production or importation to the Tags. This Tags are moved for logistical process to end point, the Korean medicine agency. The customer confirmed the traceability and certification information of the Medical Herbs. For success tracing of medical herbs, institutional support and close cooperation between related organizations is necessary besides good system design.

  • In the middle of the 8th century, we met the new high-rise building, the 7th storied wooden pagodas in 'Kokubunji' in Japan. I tried to analyze and study this building to show how the wooden pagoda had changed itself because of appearance of new style. The conculusions are as follows; 1. The construction of the foundation was mainly composed namely 'Panchuk'. It was proceeded by two ways. One is the earthen-digging, laying foundations named 'Gulkwangpachuk' and the other is simply laying foundation named 'Jisangpanchuk'. In that period, due to the progress of the technique, we assumed that the main stream is 'Jisangpanchuk'. 2. The elevation of base was mostly the single foundation from archaeological study. The material was stone. The middle case of pagoda had the base of tile-roofed. We knew the just one pagoda had the base of brick, but that was not main stream. 3. The new device had appeared in the central base stone. It was the stone point. But in that period the existing method, a hole style and the new style was used in the central base stone. This fact is showed that the central government was not hold the reigon(it names 'Kook') in the respect of the technique. 4. The plan scale is classified of 3 group. As a result, the first body is larger, the main-unit and the sub-unit is a equal unit. But smaller, the length of main-unit is longer than the one of sub-unit. And the very small pagoda was build in that period.

  • Objectives: This study aims to evaluate the effectiveness of a lifestyle intervention on the improvement of obesity, health behaviors and behavioral determinants among Korean adults. Methods: Obese adults aged 30 to 59 years (n=76) were randomly assigned to the intervention group (IG) or the comparison group (CG). The IG received a 3-month multi-component lifestyle intervention, while the CG received minimal information on obesity. The program consisted of health counseling, health education booklet and health diary. Health examination and self-administered survey were conducted before and after the intervention to determine the effectiveness of the program. Results: After the intervention. health indices of the IG were significantly improved in weight(p=.003), waist circumference(p=.011), % body fat(p=.021), and total abdominal fat area(p=.041). The reduction of waist circumstance among IG participants was better than that of those in the CG(p=.017). The IG demonstrated significant improvements in dietary behaviors(p=.013), periodic measurement of waist circumstance(p=.005), pros of weight control(p<.001) and awareness of one's current biomarkers(p=.038) better than the CG did. The proportion of normalized participants in waist circumference was 21.1% in the IG and 8.7% in the CG(p=.017). Conclusions: Lifestyle intervention program can improve the obese status and health behaviors in adults.

  • The farmers' nutritional condition can not be compared with other citizens according to the Korean National Health & Nutrition Examination Survey, and based on other literature reviews. These farmers have either less access to educational materials or have no idea and do not understand the importance of nutritional education. The purpose of this study is to develop an appropriate reading material on nutrition to educate the farmers. To do this, the first step was to gather sufficient available materials for the review of related literature. Second, a survey was conducted to assess the needs of farmers and extension workers for educational materials on nutrition. The results showed that the farmers preferred the following topics: Menu Planning or Menu for Health' (62.1%), Dietary Assessment (49.7%), Dietary Guideline for Farmers (35.7%), and Cooking Method and Recipe (32.6%). They also preferred the booklet type (62.7%). These materials basically contained literature review, lesson plan, and needs assessment. The booklets contained in detail: 1) Dietary assessment - nutritional assessment, and assessment of meal 2) Dietary guidelines for farmers - reduce salt intakes, eat calcium-rich foods, ideal body weight, reduce alcohol-drinking and smoking, tips on eating soybean, eat meat and fish, tips on eating fruits, eat shellfish and seaweeds, and tips on eating dietary fibers, and 3) Plan a meal - menu planning and sample menu by farming patterns. Finally, the text of the final material was improved by the graphic designer using Quark Express 3.3, Photoshop 6.0, Illustrator 10.0, and Painter 8.0. The booklet has 46 pages and divided into three chapters. This contains simple and affordable recipes and provides some helpful tips for dietary and changing lifestyles. This booklet is made available for farmers and other groups interested in nutrition education.

  • Purpose: Currently, using perforator artery flaps especially anterolateral thigh flaps are widely used for reconstruction of extremities, head and neck. Obtaining a precise anatomical picture prior to operation will translate to a more accurate, efficient and safe procedure. Authors used 3D-image work up via 64-slice MDCT to make a more precise preoperative plan. Methods: A total of 10 patients underwent soft tissue reconstruction with anterolateral thigh flap from December 2006 to December 2007. The 64-Channel MDCT (LightSpeed VCT, GE, USA) was used and 3D images were reconstructed. Findings from MDCT were applied to the preoperative planning and confirmed with intraoperative findings. Results: The average number of perforator arteries from lateral circumflex femoral artery was 2. The average lengths of vascular pedicle from the origin of lateral circumflex femoral artery to the first and second perforator artery were 11.0 cm and 20.0 cm, respectively. The average diameter of the pedicle artery was 2.2 mm. The locations of the perforator arteries were mapped and localized on the body surface based on the MDCT result. These were confirmed through direct visualization intraoperatively. Conclusion: MDCT has an advantage of obtaining accurate images of the general anatomy and even fine structures like perforator arteries. By using this state-of-the-art diagnostic imaging technique, it is now possible to make an operative plan safely and easily.
