This paper presents a methodology to nominate and select improvement projects that are perceived as adding value to customers (both internal and external). The structure of the methodology can be explained in three "stages." First, the methodology suggests a new way of categorizing improvement opportunities, i.e. reactive-proactive, to "upgrade" the little Q-big Q categorisation. Then, it develops a roadmap that links performance indicators and improvement projects for both reactive and proactive improvements. Finally, it suggests an algorithm to select the improvement project, where the assessment of to what extent the nominated improvement projects add value to customers relies on the comparison between Overall Perceived Benefits (OPB) and Overall Perceived Efforts (OPE). The improvement project perceived as having the largest impact on adding value to customers receives the highest priority.

VE, rather than just cost reduction tool, have established as a value enhancement tool of the construction industry. Value improvement types of VE proposal can show the effect of VE activities, also acts as an important element in which the owner adopts a proposal and confirms the results of the VE activities. However, problems in the process of quantification for VE proposal and ambiguous standards in classification of value improvement types is need to be supplemented. Accordingly, This study suggests the plan for establishing of numerical range criteria for classification of value improvement types of VE proposal. Implementing this plan will be able to improve the reliability and availability for VE activities.

Digital images or videos are used in modern digital devices. The resolution of HDTV in digital broadcasting system is higher than that of previous analog systems. Also, mobile phone with 3G can provide images as well as video streaming services in realtime. In these circumstances, the visual quality of images has become an important factor. We can make image clear by transient improvement process that reduces transient in edges. In this paper, we present an transient improvement algorithm. The proposed algorithm improves edges by making smooth edge to steep edge. Before performing transient improvement algorithm, edge detection algorithm should be operated. Laplacian operator is used in edge detection, and the absolute value of it is used to calculate gain value. Then, local maximum and minimum values are computed to discriminate current pixel value to raise up or pull down. Compensating value that gain value multiplies with the difference between maximum (or minimum) value and current pixel value adds (or subtracts) to current pixel value. That is, improved signal is generated by making the narrow transient of edge. The advantage of proposed algorithm is that it doesn't produce shooting problem like overshoot or undershoot.

This study aims at investigating the effects of internal control effectiveness on business survival of food businesses in Thailand through the mediators of productivity improvement and value creation. In this study, 155 food businesses in Thailand are the samples of the study. The results show that internal control effectiveness has a significant influence on productivity improvement and business survival. Productivity improvement critically affects value creation and business survival while value creation is an important determinant of business survival. However, internal control effectiveness has no relationship with value creation. Also, productivity improvement explicitly mediates the internal control effectiveness-business survival relationships. In summary, internal control effectiveness can enhance firms' sustainable competitive advantage, superior performance and long-term survival. Firms need to focus on internal control effectiveness through investing their assets and resources and utilizing their abilities, competencies and capabilities in order to continuously develop and improve their appropriate concepts and characteristics in an organization. Better internal control effectiveness definitely leads to more long-term survival. To generalize the research results, future research needs to collect data from other businesses and industries. Increased response rate of the study is important for future research to verify and confirm the research results.

This research performed strength improvement analysis after evaluating strength characteristics by estimated temperatures to evaluate the real time strength performance of 50 to 80 MPa high performance concrete equipped with heat resistance, and the results are as follows. The lesser W/B and the lesser target slump flow value difference, compression strength was shown to increase, and the more curing temperature becomes, the strength increased accordingly. According to the correlation review result of strength improvement analysis by estimated temperature change performed using logistic analysis model, the compression strength value predicted with logistic curve expression and the compression strength value measured in experiment were shown to have similar correlation, and the strength improvement analysis value by logistic model was shown to be estimated good when W/B is high.

철근공사는 거푸집공사와 더불어 건축물의 구조적 안정성과 내구성 및 공기에 가장 큰 영향을 미치고 있는 공사이다. 그러나 국내 철근 콘크리트 공사는 철근현장가공조립을 주로 하고있어 낮은 생산성을 갖고 있는 실정이다. 따라서 본 논문은 생산성 향상을 위해 철근현장가공조립 프로세스를 부가가치 생산성향상을 위한 낭비요소를 분석하였다. 낭비요소 분석은 비가치창출 작업으로 인해 발생하는 요소로 철근현장가공조립의 가치분석을 통해 부가가치를 극대화 하고자 하였다. 그 결과 가치창출작업들이 비가치창출 작업보다 월등히 적다는 것으로 분석되었다. 특히, 본 논문에서 낭비는 불필요한 작업 단계와 인력, 장비, 자재, 시간 등에서 낭비되고 있었다. 또한 흐름생산이 되지 않고, 과잉생산을 하고 있는 것으로 조사되었으며, 가치의 변화가 필요한 것으로 분석되었다. 본 논문에서는 부가가치 생산성 향상을 위해 프로세스 상에 내재되어 있는 낭비요소를 분석하여 부가가치를 창출하는 가치창출 작업을 최대화하고, 비 가치창출작업을 최소화하는데 목적이 있다.

Background: This study investigates improvements in non-value-added nursing activities in clinical work, in order to improve the efficiency and quality of nursing activities. Methods: The study was performed as a quality improvement project at a tertiary general hospital. The nursing activities that needed improvements were categories into admission care, discharge care, supply management, diagnostic work-up related activities, and others. The nursing time and frequency of non-value-added activities were compared across nine nursing units before and after implementation of the quality improvement program. Post-implementation patient and nurse satisfaction were subsequently analyzed. Result: Post-implementation, the time spent on non-value-added nursing activities was reduced and patients and nurses were satisfied with the improvements. Discussion: Reducing non-value-added activities in nursing can increase the work efficiency and ensure time for patient care, thus improving the quality of nursing care. For further study, accurate surveys on nursing activities based on nursing time are required.

This study intended to enhance the quality of life of rural adolescents through survey 185 young people in YeonChun County, in the course of measuring the level of life of adolescents and finding several variables related with the level and drawing some applications for enhancement. As a result of this study we had some findings 1) the most young people were belonging to the second (vital feeling value) level and third (mental value) level 2) Sex, religion, tendency oriented to other person were three related variables with the level. The more the people having other-oriented tendency the higher the level of value. Female, Christian is higher in the level. 3) Many adolescents showed little hearty satisfaction concering their own life 4) The level of act in their real life were corresponded with the level of value 5) Characteristics of high value-level adolescents against low value-level ones were that they had high level of value-recognition, less family member. The hit ratio was 83.7 percent. On the basis of this study the following suggestions for the improvement of quality of life for youth in the rural area in the future. First, we should make a great effort in value education in order to clearly get the goal of the true life. The quality improvement such as the education of mental life and religion for the young people by developing programs to continously improve the value of life. Second, the necessity of behavior guiding other oriented tendency should be emphasized. We should connect adolescents with value recognition through more interest in actions. And third, it is necessary to make a professional effort for the improvement of level of value, that is, an in depth study of the theoretical systemization.
