  • It is well-known that the scenic visibility achieved in our naked eyes is related with the quality of aerosol condition which is composed of primary and secondary air pollutants. In recent, the IMPROVE organization in U.S.A. has developed two algorithms to estimate the visible length depending on the elements of air pollutant. Using these algorithms, we are to represent the condition of aerosol quality with the well-known scenic images of the observing area so that any one that have no sufficient chemical knowledge may feel and understand the level of air pollution in visuality.

  • Health information technology (HIT) is one of the most familiar tools to healthcare providers. It is used in routine practice to reduce cost, to improve clinical performance, and to improve patient safety. Patient safety is the driving force of recent expansion of HIT industry. But there are many evidences that it can be harmful to patient safety. Role of HIT and HIT-related error became big issues because more and more healthcare providers and healthcare organizations are willing to adopt it. Adoption rate of HIT in Korea is higher than that of United States. But researches of HIT regarding patient safety are rare. In this article, types of HIT, their mechanisms of improving patient safety and HIT-related errors were reviewed. Status of HIT in terms of patient safety in Korea was also reviewed. Knowledge of how HIT can improve patient safety, its' limitation, and how to make it safer is crucial to whom have to use it to improve patient safety. Impact of HIT on patient safety must be evaluated actively in Korea. HIT which was proven to improve patient safety must be widely adopted. Government must prepare a strategic plan to improve HIT quality, support hospitals financially and institutionally to introduce qualified HIT, and develop HIT infrastructures and standard designed for patient safety.

  • In these days, an individual is evaluated by his or her credit. So, it is very critical for an individual to know his or her credit rating and then to try to improve the credit rating. But, there are few services to analyze credit status for an individual and inform the person of the credit. In fact, it could be impossible to let a person know how to improve his or her credit rating. Against this backdrop, we research on a credit management model to analyze credit status of an individual rapidly and propose individual-customized method to improve the credit rating. We set up the model and design it in detail. This servie would certainly make it convenient for an individual to retrieve credit rating and improve it.

  • Purpose: This study was conducted in order to understand the correlation between professionalism, job satisfaction, and job performance of physical therapists Methods: Subjects included 148 physiotherapists. We conducted a questionnaire survey on professionalism, job satisfaction, and business performance. We then performed a correlation analysis. Results: The highest 'compliance of professional organization' in professionalism, the lowest 'vocation awareness of the profession'. In job satisfaction, the highest satisfaction was reported for 'supervisor', and the lowest satisfaction for 'duty'. Professionalism and job satisfaction/job satisfaction and job performance showed a clear positive correlation, and professionalism and job performance showed a weak positive correlation. Conclusion: The results of this study indicate that, in order to improve the job performance of the physical therapist, it is necessary to improve professionalism and job satisfaction. Physical therapists should improve their professionalism in order to improve job performance. In addition, research to improve job satisfaction and job performance of the physical therapist should be continued.

  • A P2P technology in distributed environments is very useful in the respect that persons to have resources efficiently share the resources. A P2P system is caused as follows : resource search, resource transmission, resource transmission again and then excessively occurred network traffic. To improve performance about this a lot of studies is proceeding. One of this various study's directions to improve performance is recently come to a field to improve usability as such person. At this point this study is proposed P2P group search algorithm to improve usability.

  • Spur Gear parts for automobile actuators using existing former forging technology were produced in a total of three processes on a former forging machine. However, in order to improve cost increase due to frequent mold breakage, Spur Gear parts were designed and manufactured in the cold forging process after forming the preform through former forging. In other words, in the existing former forging mold, product seating defects occurred due to horizontal movement, resulting in many product defects and mold damage, so there was an urgent need to improve mold life and product defects. In order to improve this, we tried to improve the mold life by improving the existing 3 former forging processes to a former forging process and 2 cold forging processes. Therefore, We developed Spur Gear parts for automobile actuators were developed by applying precision cold forging technology through a former forging process and 2 cold forging processes to improve mold life.

  • Objective: This study investigated the problems that could be faced with when engineers try to improve the affective quality using the DMAIC model. Background: Affective quality is considered one of the most influential factors for the competitive power of consumer products and many engineers make effort to improve the affective quality. Since the Six Sigma process is effective and wide-used method for quality improvement, it can also be used to improve the affective quality. However six sigma tools cannot be directly used for affective quality because of the subjective and qualitative characteristics of the human affection. Method: Investigate the goals, processes and key factors of DMAIC model and find the difficulties to use six sigma tools for the affective quality. Results: Most of the problems arise from measuring and quantifying the human affective response level and understanding the relationship between the human affective factors. Conclusion: Both the protocol for measuring human affection and the monitoring system to find the affective response change for the product or service are required. Application: The results of this study could be helpful for the engineers not specialized in ergonomics to improve the affective quality in systematic approach.

  • The purpose of this experimental study is to improve the workability and durability in high sulphated cement concrete with fly-ash. As a results, we can make high strength concrete by using only high sulphated cement but try to improve the workability and degree of strength by adding 10% fly-ash but the effect beyond my expectation to improve the workability and degree of strength does not show, and the improvable effect except the drying shrinkage of durability dose not show, either. So we must give attention to using fly-ash.

  • The Newton-Raphson method has now gained widespread popularity in Load-flow calculationes. In this paper programming is developed with aims to improve the convergence characteristics, speed and memory requirements in the above method. The method of Load-flow calculations is performed by employing the MW-O/MVAR-V decoupling principle. To reduce the memory requirements and improve the speed of calculation the programming of the Optimally Ordered Triangular Factorization method is developed. Besides this, other measures are taken to reduce memory requirements and computing time and to improve reliability. KECO'S 48 Bus system was tested and the method suggested in this paper was proved to be faster than any other methods.
