A noncoherent, broadband, intense pulsed light source has been used for the symptoms of photoaging skin as a nonablative method. The purpose of this study is to investigate the efficacy and tolerability of intense pulsed light in solar lentigines and ephelides on the face. An open study was performed in patients with solar lentigines and ephelides who received three to five treatments of intense pulsed light. Forty-eight percent of patients had more than 50% improvement and 20% had more than 75% improvement. In the group of solar lentigines, 40% of patients showed more than 50% improvement and 16% did more than 75% improvement. Patients with solar 1entigines＋ephelides and ephelides responded remarkably with 75% and 71 % of patients having more than 50% improvement, respectively. Intense pulsed light was well tolerated and may be a new modality for the therapy of solar lentigines and ephelides.

With introduction of amended educational curriculum in 2007, optimizing project of educational environment to accomplish its purposes and goals includes expanding educational facilities and supplying eco-friendly school facilities. However, while the focus of optimizing project of educational environment is quality improvement of educational facilities, aging of these facilities built at th times of quantitative expansion and its management become serious problems. Higher concerns on studies and jobs on management of building caused by serious aging of facilities, management cost of building becomes a very crucial issue. Therefore, this study aims to analyze environment improvement budget of school facilities through building and using data warehouse, by investigating and analyzing the current status of environment improvement budget of school facilities and its cost through questionnaire and interview surveys on officers who are in charge of environment improvement budget of school facilities in educational administrations. This study thus analyzed environment improving budget of school facilities by using data warehouse technology collecting related data to the topic and setting levels by region, school class, establishment year, school facility types and others.

본 연구는 안전성, 노후도, 경제성 등 시설 여건을 종합적으로 고려하여 개선이 필요한 중장기적인 사업물량 및 사업예산 규모를 추정할 수 있도록 하기 위해 국가수준의 시설개선 기준(수선주기)을 설정하여 체계적인 시설개선계획 수립을 통한 적정수준의 교육환경 확보에 기여할 수 있도록 하는 것을 주목적으로 한다. 적정 수선주기는 기본적으로 최근 2년간 교육청에서 실제 집행한 교육환경개선사업의 실적자료를 분석하여 직전 보수년도와 사업시행연도를 근거로 수선주기 기초자료를 산출하였다. 이를 근거로 17개 시도교육청 실무자를 대상으로 델파이 조사를 실시하여 시도교육청의 의견을 수렴하였으며 최종 적정 수선주기는 관련규정과 실적자료, 델파이조사 결과를 종합적으로 검토하여 설정하였다.

Continuous quality improvement is now the focus of research and application in quality engineering. To achieve continuous improvement, it's necessary to integrate quality tools and to plan, design and control the whole process of creating quality. Based on the extensive literature review and the philosophy of concurrent quality engineering, the paper analyzes the relationships among major quality tools such as QFD, FMEA, DOE and SPC and presents a basic model and structure for the integration of quality tools.

The purpose of this paper is to propose an appropriate evaluation scheme for improvement activities, based on a simple model comprising cash inflow by sales as well as variable and fixed cost expenditures. The paper distinguishes capacity surplus and capacity shortage situations, and examines economic benefits gained by yield increase improvement and capacity increase. The paper then proposes a basic rule of thumb for economic evaluation of improvement activities. The logic is simple but useful in practice, being conducive towards improvement activities under current economic conditions with uncertainties.

The goal of this study is to present efficient measures to improve the quality of medical education through using a developed and applied continuous quality improvement (CQI) model suitable for medical education. To achieve this purpose, we developed a theoretical CQI model through a review of the literature according to the design-based research method. Through repetitive productive cyclical processes and professional reviews, we finally deduced an appropriate CQI model for medical education. The most important results of this study are as follows: First, the CQI model for medical education is defined as a quality management system with a cyclical course of planning, implementation, evaluation, and improvement of medical education. Second, the CQI model for medical education is composed of quality management activities of educational design, work, and evaluation. In addition, each activity has the implementation strategies of planning, doing, checking, and improving based on the PDCA model (Plan-Do-Check-Act model). Third, the CQI model for medical school education is composed of committees related to medical education doing improvement activities, as well as planning, implementing and evaluating it with CQI. As a result, we can improve teaching by using the CQI model for medical education. It is more meaningful because this gives us organized and practical measures of quality management and improvement in medical education as well as in the educational process.

In this study, the status of existing school facilities improvement project is done individually, based on the systematic integration of the improvement project was to evaluate the feasibility. Furthermore, it was based on looking for ways to effectively pursue. Training School Facilities Improvement Program to be competitive, the country continued to be pursued systematically and very large scale as a whole must be a great national project. So much to promote efficient business environment, quality of education for children with detractors of the national budget to ensure efficient and most importantly in terms of economic investment that can be.

Purpose: The pharyngeal flap is one of the popular surgical method to treat the problem of velopharyngeal dysfunction. This study evaluated speech outcomes of patients who underwent superiorly based pharyngeal flap surgery based on timing of surgery. Methods: A restrospective review of 50 patients who underwent pharyngeal flap surgery for velopharyngeal insufficiency between September 1996 and January 2008 was undertaken. Thirty patients with an available preoprative and postoperative speech assessments with at least 6 months of follow-up were included in this study. We checked out the significance of speech improvement after surgery analysing preoperative and postoperative scoring of speech assessment. We also investigated the direct relationship between the age at surgery and the degree of speech improvement, and the improvement score in different age groups. Results: The mean score of preoperative speech was $52.6{\pm}7.4points$ and postoperative speech was $58.6{\pm}6.5points$, which presented significant postoperative speech improvement with an average of 5.9 points(p<0.01). There was a significant inverse relationship between the age at operation and speech improvement degree(p<0.01, r = -0.54). Comparing the age groups, the age group of 4 to 5 years presented statistically significant speech improvement(p<0.01). Conclusion: we propose that all patients indicated should take pharyngeal flap irrespective of age. In this study, the younger the age at surgery, the higher degree of speech improvement, for which we suggest that surgical approach should be undertaken as early as possible, especially younger than age 5 years.
