The aim of this study is to find out problems between the '7th National Curriculum' and '2007 Revised National Curriculum' that would initially apply from 2009 and then to suggest better ways to improve computer education in Middle schools. A survey was carried out with a questionnaire. Based on the result, a comparison was made and a suggestion has been derived: Firstly, the computer subject should not be treated as a rival to others anymore, rather it should be considered as an essential subjects. Secondly, teachers who take computer subjects as their major should be allocated to middle schools. Thirdly, computer subjects should be taught systematically from elementary and be continued throughout in order to promote the level of the computer science education. Fourthly, the advantages of computer utilisation should be taken into account to layout the computer curriculum that is practicable and learner-centered. Finally, teachers should recognise the main aim of computer education and teach computer subjects to be useful in education. Though the revised version is not perfect the more the curriculums are revised, the better they might be expected to be developed. Consequently, whenever the newly revised computer curriculum emerges, the defects should be identified and addressed in order to achieve the aim of the computer curriculum.

This study examined sewing methods used to reinforce the opening of clothes of the Joseon period. Through the analysis of a total of 117 clothing items of the Joseon period, the following results were obtained. 1. Most costumes of the Joseon period had the opening. The purpose of the opening was to allow one to put on and take off a costume, act comfortably, and turn a costume Inside out. The opening was located on the Side, Conte. Back, fgwi(Side opening of pants), Wristband, Armhole, and Godae(the bark part of the collar). 2. As the opening tended to get easily worn out, it was often reinforced. The 1911owing three methods were used to reinforce the opening of clothing items of the Joseon period: a method to attach a cloth such as Dang, Binding, and Badae; a method using a variety of knots; and a method by sewing stitches such as a sort of cross stitch called Satteugi, Prick stitch, and Loop. 3. The most frequently used reinforcing method was the one that used a knot(34 items), followed by the one by sewing Satteugi(27 items), and the one using Dang(25items). The most frequently detected location of the opening was Side(59 items), followed by Agui(37 items), Wristband(19 items), and Center Back(13 items). 4. The reinforced opening made a costume more endurable and elastic, decorative and neat.

The purpose of this study was to improve EMS-System in Korea through the research in EMS-System of advanced country. The response time is defined as the interval from the time of call receipt to the time of scene arrival. The important factor was to shorten moving distance of ambulance. It should be considered to accomplish this factor that the vehicle must be increased and the convenient location chosen for optimizing of service area. The transport of emergency patients carried out almost by 119 Emergency Medical Service but out of all the employees at 119 EMS only 11.3% have own qualified EMT degree. They should be employed more and more specially at 119 EMS for a superior level of emergency medical care for civilian. In America, EMT can take care of emergency patients following the order from medical Director at the scene of accident. But in Germany, prehospital care was emphasized from the beginning and, in those days, a medical doctor was sent for treatment of emergency patients at the scene, the so-called a Rendezvous system. Hierby this study makes the suggestion to improve the EMS-System, it is effective to use the medical Director system in America and furthermore a Rendezvous system in Germany. The functional integratin and unification of the report system as well as enough personal and equipmental elements saved together invaluable lives.

기업의 경영환경은 급속히 변화하고 있으며 특히, 새로운 경영패러다임으로 가치중심의 경영사고는 급속히 그 중요성을 인정받고 있다. 이러한 경영환경의 변화에 대한 신경영기법의 활용에는 원가/관리회계정보가 기초적 역할을 수행하고 있는데, 과거 지향적인 정보보다는 실시간적이면서 동시에 미래지향적인 정보를 제공해야만 경영의사결정에 도움을 줄 수 있다. 이러한 실시간적 정보와 미래 지향적인 정보의 중요성을 인식하면서 조직을 가치창출 중심적인 방향으로 움직이게 하기 위해서는 조직내 구성원 및 조직의 성과평가가 중요한 문제로 대두될 수 있다. 그러나 과거와 같이 전통적인 성과측정치로 재무적 측정치를 사용하면 조직의 유효성을 증진시키는데 한계가 있을 뿐만 아니라 가치창조를 저해시킬 소지도 있다. 따라서 앞으로 조직을 가치 지향적이 되게 하기 위해서는 조직의 구성원 및 조직단위의 성과를 측정할 때, 재무적인 측정치와 비재무적인 측정치의 균형있는 사용을 강조하는 Balanced Scorecards개념을 도입하는 것이 바람직할 것이다.

It is very insecure to treat a butane can for cooking out of door. The human injury from the accidents of butane cans has been getting increased 1.5 times yearly since 2003. In this context, the Institute of Gas Technology Training in Korea Gas Safety Corporation carries out explosion experiment to make trainees to take all possible measures to ensure safe management of gas in the field by fully recognizing the hazards of gas explosion accidents. This study intends to examine the influence of such explosion experiments on the trainees witnessing nearby. The GEN exposed to the active students participating in the experiment away from 25 meters from the explosion site was 57.94 dB and the GEN to the passive students not participating away from 50 meters was 51.92 dB. According to Weber-Fechner's law for the lower value than 65 dB which is the environmental standard, it is safe from the place 15 meter far from the explosion place. The environmental standard of offices is 50 dB, and it is lower than the environmental standard if the office is 65 meter far from the explosion place.

This paper is proposed new fuzzy controller for high performance of interior permanent magnet synchronous motor (IPMSM) drive New fuzzy controller take out appropriate amounts of accumulated control input according to fuzzy described situations in addition to the incremental control input calculated by conventional direct fuzzy controller. The structures of the proposed controller is motivated by the problems of direct fuzzy controller. The direct controller generally give inevitable overshoot when one tries to reduce rise time of response especially when a system of order higher than one is under consideration. The undesirable characteristics of the direct fuzzy controller are caused by integrating operation of the controller, even though the integrator itself is introduced to overcome steady state error in response. Proposed controller fuzzy clear out integrated quantities according to situation. This paper attempts to provide a thorough comparative insight into the behavior of IPMSM drive with direct and new fuzzy speed controller. The validity of the comparative results is confirmed by simulation results for IPMSM drive system.
