Single PPM Quality Innovation activity made a great contribution to strengthening the quality competitiveness and the international competitiveness for the domestic small and medium enterprises. But it doesn"t work to companies that deal with the partic

목적 : 척수손상 환자를 대상으로 시각피이드백을 이용한 휠체어 추진이 척수손상 환자의 균형 특성에 미치는 영향을 알아보고자 하였다. 연구방법 : 척수 완전 손상 환자 38명을 대상으로 휠체어 추진 시뮬레이션 장치와 휠체어를 추진하지 않는 경우와 추진하는 경우 시각피이드백 이용유무에 따른 둔부와 대퇴부의 압력분포와 압력중심이동 변화를 측정하기 위해 좌석시트 압력분포 측정도구인 FSA를 사용하였다. 이들 실험도구들을 이용하여 얻은 결과는 다음과 같다. 결과 : 1) 시각피이드백 이용 없이 휠체어를 추진하지 않는 경우와 추진하는 경우에 압력중심의 흔들림이 유의한 차이가 있었다(p<.05). 2) 휠체어 추진 시 시각피이드백을 이용하지 않은 경우보다 시각피이드백을 이용한 경우에 척수손상 레벨에 상관없이 압력중심의 흔들림이 모두 감소되었다. 시각피이드백 이용 유무에 따라 흉수상부 손상, 흉수하부 손상, 요수 손상 환자에 있어서는 유의한 차이를 보였다(p<.05). 3) 경수 손상 환자의 부위별 좌석시트 압력분포 평균을 보았을 때, 휠체어 추진 시 둔부전방 > 둔부후방 > 대퇴부 후방 > 대퇴부 전방 순으로 압력이 분포되었으며, 휠체어를 추진하면서 시각피이드백을 이용한 경우의 부위별 압력 증가비율을 계산한 결과, 둔부전방과 대퇴부 부위로 더 많은 압력증가가 생겼다. 4) 흉수상부 손상 환자의 부위별 좌석시트 압력분포 평균을 보았을 때 휠체어 추진 시 둔부전방 > 대퇴부 후방 > 둔부후방 > 대퇴부 전방 순으로 압력이 분포되었으며, 휠체어를 추진하면서 시각피이드백을 이용한 경우의 부위별 압력 증가비율을 계산한 결과 둔부전방과 대퇴부 부위로 더 많은 압력증가가 생겼다. 5) 흉수하부 손상 환자의 부위별 좌석시트 압력분포 평균을 보았을 때 휠체어 추진 시 둔부전방 > 대퇴부 후방 > 둔부후방 > 대퇴부 전방 순으로 압력이 분포되었으며, 휠체어를 추진하면서 시각피이드백을 이용한 경우의 부위별 압력 증가비율을 계산한 결과 대퇴부 부위로 더 많은 압력증가가 생겼다. 6) 요수 손상 환자의 부위별 좌석시트 압력분포 평균을 보았을 때 휠체어 추진 시 둔부전방 > 둔부 후방 > 대퇴부 후방 > 대퇴부 전방 순으로 압력이 분포되었으며, 휠체어를 추진하면서 시각피이드백을 이용한 경우의 부위별 압력 증가비율을 계산한 결과 둔부후방으로의 압력 증가비율이 가장 많이 증가하고, 다음으로 대퇴부 전방, 그리고 대퇴부 후방 순이었다. 결론 : 시각피이드백을 이용한 휠체어 추진 시 척수손상 레벨에 상관없이 압력중심의 흔들림이 모두 감소하였다. 또한, 전방 또는 전후방으로의 압력분포 변화를 통해 균형의 향상을 가져올 수 있는 움직임이 더 증가하는 경향이 있었다. 이를 통해 시각피이드백을 이용한 휠체어 추진이 척수손상 환자의 균형능력 향상에 도움을 줄 수 있음을 보여주었다.

As many other countries, We have ‘presentence investigation system’ in Korean criminal justice system. But, in comparison with other country’s system like America or England, our system is imperfect. That is to say, our presentence investigation system is legally applied only to juvenile criminals. In addition, though Korean probation and parole office have the power of presentence investigation, this power is not effectively used. So, legally, adult criminals have been sentenced in a court without presentence investigation process. And consequently, their mental disorder, home background, social environment, the cause of crime and so on are not precisely considered in a court. So, such sentencing have some problems that is unscientific, regimental, and none effective to criminal’s treatment and rehabilitation. Fortunately, Presidential Committee on Judicial Reform has made a law about presentence investigation, but this law also have many problems. That is to say, this law rules the subject of presentence investigation dualistically - court official and probation officer. Such system is not discovered in any other country, and this may cause chaos of presentence investigation process and may result in the squandering of national budget. So, this article indicate the importance of complete presentence investigation system and that we should made a law of presentence investigation system more systematically and unitarily.

ILM(incremental launching method) 교량공법은 품질확보에 효과적인 프리스트레스트 콘크리트 교량공법으로 인정받고 있다. 이 공법에 의해 시공되는 교량의 상부단면은 시공 중에 지간의 중앙부와 지점부에 일시적이나마 모두 위치하게 된다. 따라서 단면들은 자중에 의해 발생되는 최대 정 모멘트와 최대 부 모멘트, 그리고 최대 전단력을 모두 경험하게 되는 구조적 특성을 가지고 있다. 한편, 압출하는 동안 발생하는 높은 일시적 응력을 최소화하기 위해 일반적으로 압출추진코가 이용되고 있다. 그리고 상부단면에 발생하는 이 일시적인 응력의 크기는 압출추진코의 특성에 따라 달라진다. 본 연구에서는 압출 중 상부단면에 발생하는 단면력의 크기를 쉽고, 빠르게 검토할 수 있는 해석식을 유도하였다. 개발된 해석식에서 고려할 수 있는 매개변수로는 압출추진코와 상부단면과의 지간 길이비와 중량비 그리고 강성비를 택하였다 특히, 개발된 해석식에서는 변단면인 압출추진코의 단면형상과 다이아플램을 고려할 수 있다. 또한, 설계변수들에 대한 민감도 해석을 통하여 압출추진코와 상부단면의 상호작용에 미치는 매개변수들의 영향을 분석하였다.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. Recently

Even though, the recent management innovation techniques: The 'Six-Sigma' and the 'BSC (Balanced Score Card)' are introduced to many different companies and are used very effectively. Based on the company's substantial and unique characteristics, the quality and the strategies on management are showing the reliability limits in applications in the company. Therefore, the Integrated Management System is presenting a model for stable application of the activity in the Six-Sigma based on the theoretical notions of the BSC.

Service and administration departments in several companies adopt a program called Six Sigma, in order to make fundamental changes in Korea and abroad. This paper is concerned with a six sigma DMAIC road map for service and white-color management process. This road map consists of 13 steps which considers the employee's majors and characteristics of the business process, For commercial quality, the proposed road map were actually applied and successfully fulfilled to H company.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier"s quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. Recently 1,053 companies is received Single PPM Quality Certification from government. This quality program is to realized the anticipated results not only quality level"s increasing, but also company"s confidence, competitiveness. We were able to obtain participations of 75 questionnaire, and derived statistics by means of SPSS/PC version 10.0. In this study, we find the bottleneck factor for promotion and upgrade S-PPM, and suggest a way out of difficulties.

Pressure ulcers are serious complications of tissue damage that can develop in patients with diminished pain sensation and diminished mobility. Pressure ulcers can result in irreversible tissue damage caused by ischemia resulting from external loading. There are many intrinsic and extrinsic contributors to the problem, including interface tissue pressure, shear, temperature, moisture, hygiene, nutrition, tissue tolerance, sensory and motor dysfunction, disease and infection, posture, and body support systems. The purposes of this study were to investigate the relationship between buttock interface pressure and seating position, wheelchair propulsion speed. Seated-interface pressure was measured using the Force Sensing Array pressure mapping system. Twenty subjects propelled wheelchair handrim on a motor-driven treadmill at different velocities (40, 60, 80 m/min) and seating position used recline (, , ) with a wheelchair simulator. Interface pressure consists of average (mean of the pressure sensor values) and maximum pressure (highest individual sensor value). The results of this study were as follows; No significant correlation in maximum/average pressure was found between a static position and a 40 m/min wheelchair propulsion (p>.05). However, a significant increase in maximum/average pressure were identified between conditions of a static position and 60 m/min, and 80 m/min wheelchair propulsion (p<.05). No significant correlation in maximum pressure were found between a recline (neutral position) and a , , or recline of the wheelchair back (p>.05). No significant difference in average pressure was found between conditions of a recline and both a and recline of wheelchair back. However, a significant reduction in average pressure was identified between conditions of a and recline of wheelchair back (p<.05). This study has shown some interesting results that reclining the seat by reduced average interface pressure, including the reduction or prevention in edema. And interface pressure was greater during dynamic wheelchair propulsion compared with static seating. Therefore, the optimal seating position and seating system ought to provide postural control and pressure relief. We need an education on optimal seating position and a suitable propulsion speeds for wheelchair users.

This thesis investigates the feasibility and advantages of establishing a more efficient distribution system utilizing new technologies such as the internet and radio frequency identification (RFID). Introducing and promoting the diffusion of commodity traceability (the ability to trace the distribution route of products and materials) is necessary in order to make distribution and logistics more efficient, to clarify the safety of foods and daily necessities, to prevent theft and to monitor the dealing of stolen or imitation goods. This thesis focuses especially on a commodity (products) traceability system to enhance transparency for consumers. The expected effects of RFID can be summarized as follows. - Substantial improvement in logistics efficiency. - Higher consumer safety, quality management, and security for foods, drugs, and goods (clothes, books, electric appliances, automobiles, etc.) through improved traceability.
