Continuous Improvement is a central concept in the quality movement. In almost all descriptions of quality initiatives Continuous Improvement is central. Even in ISO 9000:2000 that has been recognised. In this paper we will discuss the role of continuous Improvement within the quality movement, its relation to knowledge management and, especially, its origin in pragmatic philosophy.

Since 100PPM Quality Certification System has been established by the Industrial Advancement Administration in 1995, 100PPM duality Innovation movement has contributed much to the enhancement of qualify competitiveness of Korea's parts industry. And in 2000, raised to a higher level, Single PPM qualify Certification System has been established by the Small and Medium Business Adminstration. The quality target is below the 10ppm(parts per million) in outgoing qualify and delivered goods plus field claim. Recently 1.818 companies is received Single PPM Quality Certification from Government. Single PPM Quality Innovation movement is perfection movement which is suitable for 21C's social-economical criteria to pursuit of zero defect. The purpose of this study is to suggest the Kano Model based Global Sustainable duality Innovation(GSQI) Index to improve current problems of Single PPM Quality Innovation Movement.

Through spot-investigation and observation of water quality environment of Jinhae Bay, this conducts the sea movement simulation on the current water quality of Jinhae Bay, grasps the flowing characteristics of Jinhae Bay and carries out ocean pollution simulation by using the data collected. Sea movement simulation results are tested by using Ocean Investigation Bureau's data of tide and current, and are also used in the ocean pollution spreading simulation. Water quality spreading simulation is conducted by using the data of sea movement and data of observation and then the results are compared with data of spot investigation. COD condensity is calculated and the water quality characteristics of Jinhae Bay are grasped.

6 sigma movement is the most prominent quality improvement methodology in practice. Measurement plays an important role in helping any organization improve quality. Therefore, the measurement systems analysis is the first step for the quality improvement of manufacturing process in 6 sigma movement. In this study, we investigate the effect of Gage Repeatability and Reproducibility(Gage R&R) in view of defect rate and process capability indices, and provide guidelines for acceptance of gage repeatability and reproducibility(%R&R) for six sigma quality.

Korean QM movement is initiated by Government from 1992 as a new industrial promotion policy instead of past Japanese style TQC movement. There has been much confusions among Korean QM, TQC, and western quality management or TQM. This paper presents the domain and the characteristics of QM to distinguish it from past TQC propulsion.

In this thesis, we suggest questionnaire which is designed to understand of what employees include executive think about 6 sigma management movement and to find important factor for strategic of success 6 sigma management movement of K. Corporation. This thesis is composed of 2 parts, one is questionnaire design and the other is questionnaire analysis. We find important factor for strategic of success 6 sigma management movement of K. Corporation by using correlation and regression analysis, which results very useful and great help for K's Co. In questionnaire analysis, we use by minitab package version 13.2.

The sleep measurement system is important to detect sleep disturbances as early as possible to be diagnosed and treat the diseases quickly. This paper presents design of system to measure the quality of sleep by using nine accelerometer sensors embedded in the pillow to detect the acceleration of limb movement, e.g. head movements. The participants were asked to sleep using a smart pillow for five days. While sleeping, participants are recorded using a camera on a computer. After awakening, participants were asked to fill out a post-sleep questionnaire. Spearman's correlation was performed to test the correlation of gross body movement per minute rate with post-sleep questionnaire questions. Finally, the seven score of sleep quality were tested with gross body movement per minute rate. The result is the higher gross body movement per minute during sleep represented lower sleep quality.

Many architects in the second machine age experiment on the movement in architectural design. They consider a movement as a flow of information and vector as well as the real motion. They express the movement in architectural design as nomad architecture, network city, rhizome, mutual transformation among building, environment and visitors, and form generation as the actualization of the virtual. It is partly the result of the philosophy of Deleuze and Bergson that a movement is just a duration as a difference of quality. It is because Deleuze explains that the realization of the virtual as a becoming is also the kind of movement. This study analyzes the method of expression of movement in architectural design in the second machine age. As a result, the movement in architectural design in the second machine age was expressed in two ways. One method is a territorialized movement that moves in the fixed trajectory and the other is a deterritorialized movement that moves in the random indeterminate trajectory.

Objectives: Restless leg syndrome (RLS) is a common sensorimotor disorder and is frequently associated with periodic limb movement in sleep (PLMS). Also about one third of patient with RLS have periodic limb movement during wakefulness (PLMW). However there is little research on the correlation between PLMW and RLS. We aimed to evaluate difference in sleep characteristics between patients with RLS with PLMW and those without PLMW. Methods: Our study included twenty eight RLS patients. Subjects underwent suggested immobilization test (SIT) prior to one full-night polysomnography study. Patients were classified into two groups according to the presence of PLMW based on SIT-PLMW index. Polysomnographic findings, subjective sleep quality, and hematologic results were analyzed and compared between the two groups. Results: Mean age of patient with frequent PLMW (SIT-PLMW ${\geq}40/hr$) was significantly higher. RLS patients with frequent PLMW were also significantly related to insomnia severity. The PLMS index was higher in patients with PLMW and showed a significant correlation with the PLMW index. Conclusions: PLMW influence sleep quality such as insomnia and is correlated with movement during sleep.

This study is to investigate effects of thermal conditions on sleep. Five female university students participated in the sleep experiment. Three temperature levels (22, 26, and $30^{\circ}C$) were given, and relative humidity was maintained to $50\%$. When as subject arrived in the chamber at 9 o'clock in the evening, questionnaire was given to check physical and psychological conditions. After checking conditions, subjects went to bed till 07 : 30 in the morning. Body movement was checked during sleeping. After sleep in the chamber, questionnaire was given to the subject in order to check sleep quality. Subjects evaluated sleep quality by themselves by answering the time they fall asleep and wake up, frequency of wake during sleep, causes of each waking, and feeling after sleep. Sleep quality was rated with 7-point scale. At $30^{\circ}C$ condition, body movement was significantly higher than of other thermal conditions. The best sleep quality was obtained at the $26^{\circ}C$ condition, while the worst sleep was taken at the $30^{\circ}C$ condition.
