  • Given the specific mean shift outlier model, the standard approaches to obtaining test statistics for outliers are discussed. Accuracy of outlier tests is investigated using subset curvatures. These subset curvatures appear to be reliable indicators of the adequacy of the linearization based test. Also, we consider obtaining graphical summaries of uncertainty in estimating parameters through confidence curves. The results are applied to the problem of assessing the accuracy of outlier tests.

  • Several statistical procedures for assessment of bioequivalence of variabilities between two drug formulations in bioequivalence trials are reviewed and modified methods for assessing total variability are suggested. The problem of the current US FDA aggregate criterion for population bioequivalence and the necessity of disaggregate criterion are discussed with an illustrated example.

  • 기능성게임은 교육, 치료, 훈련 등과 같은 본연의 목표에 따라 이용자들에게 선택된다. 따라서 해당 게임은 게임 내 외부에서 목표의 성취 여부를 평가받게 된다. 기능성게임의 품질요소 가운데 평가성은 목표 성취여부를 파악하는 기능이 게임 내에 포함되어 있는가에 관한 것이다. 본 논문은 몇 가지 사례를 통하여 기능성게임의 성취도 평가 기능을 살펴보고, 나아가 영어 학습을 위한 기능성 게임을 개발할 때 활용할 수 있는 성취도 평가 기능을 레벨 시스템에 적용하여 설계하였다. 이 레벨시스템은 경쟁과 보상이라는 게임의 핵심 요소를 이용하였고 교육부 고시에 근거하여 이용자의 영어 수준에 따라 등급이 결정되도록 시뮬레이션을 거쳐 설계한 것이다. 본 논문은 성취도 평가기능을 포함한 영어게임 설계에 유용하게 참조될 것이다.

  • 국내의 여러 지자체와 신도시에서는 U-Eco City를 구축 계획 중에 있으며 정보통신 기술의 발달에 힘입어 다양한 서비스와 기술이 적용되고 있다. 그러나 U-Eco City 사업이 활발히 추진되는데 반하여 기술적용의 객관성 검증을 위한 연구는 매우 드문 실정이다. 본 논문에서는 U-Eco City에 적용되는 기술의 결정을 위한 기술평가를 목적으로, U-Eco City의 분야별 기술을 검토하고 분야별 기술의 평가항목을 도출하고자 하였다. 이를 위하여 분야별 기술의 진화과정과 기존의 U-Eco City 기술분류체계를 살펴보고, 개별 기술의 미래적 방향성을 탐지함으로써 장기적 활용이 가능한 U-Eco City 기술평가항목을 제시하였다. 연구 결과 U-Eco City 기술은 정보 수집기술(센서, 상황인지, 영상인지, 위치인식 기술), 정보 가공기술(임베디드 S/W 기술), 정보 활용 기술(네트워크 기술) 등 총 6개 분야로 제시되었으며, 이들 기술의 분야별 평가항목을 도출하였다.

  • Objectives : The prevalence of Allergic Rhinitis (AR) has increased during the last decade. However, a lot of decisions on the assessment and treatment of AR are made depending on the personal experiences and choices of physicians. To suggest preferable approaches and to minimize the variations according to physicians, guidelines for assessing anterior nasal cavity using nasal endoscopy on AR is needed. Methods : The Korean Oriental Medical Ophthalmology, Otolaryngology and Dermatology Society and the Korean Oriental Preventive Medical Society has set out to develop the guidelines for the assessing anterior nasal cavity using nasal endoscopy on AR. Results & Conclusions : This is the first Korean guideline for the assessment of AR and should be revised and supplemented in the future as new evidence becomes available.

  • Background: Airborne radioactive particulate in many important nuclear facilities (particularly nuclear power plants) will have a strong impact on the relative public dose if they are released into the corresponding environment traversing the stack or vents. The radiation protection researchers have regarded the relative environment assessing and estimation of public doses. And the model of assessing impact of discharges radioactive substance to the environment have been recommended by many international organizations (e.g. IAEA) with the nuclear energy safety and radiation protection. Materials and Methods: This paper introduced the generic models that were suggested by International Atomic Energy Agency (IAEA), for use in assessing the impact of discharges of radioactive substances to the environment (e.g. IAEA Safety Report Series No.19). Results and Discussion: The writers of this paper, based on the recommend methods, assessed the discharge limits in some airborne radioactive substances discharging standards. The reasons that IAEA method are introduced are mainly the following considerations: IAEA is one of international organizations with some authorities in the nuclear energy safety and radiation protection; and, more important, the recommend modes are operational methods rather than the methods having little operations such as that have used by some researchers. Conclusion: It is wish that the introduced methods in this paper can be referenced in draft or revise of the standards related to discharges of radioactive substances to the environment.

  • A wetland is an ecosystem which is the most useful and highly-energetic transition area. This study has been carried out to develop the wetland function assessment methods and apply on the natural wetlands (Mul-young-ari wetland in Jeju-island and Bangdong wetland in Taejon Metropolitan city) using RAM (Rapid Assessment Method). The RAM is useful method for assessing the wetland functions in terms of general functions acquired by once or twice onsite surveying. Eight functions of 2-12 variables each are analyzed for assessing the wetland functions. The results are as follows : 1) The conservation values of two wetlands are "High". 2) In Mul-young-ari wetland, such functions as groundwater discharge, floral diversity and wildlife habitat, shoreline/stream bank protection are relatively high, but some functions such as flood/storm water storage, aesthetics and recreation are "Moderate" - "High". 3) In Bangdong wetland, such functions as floral diversity and wildlife habitat, groundwater discharge, flood/storm water storage, aesthetics and recreation are high, and another functions are "Moderate" - "High". The taxonomy of this study stems from assessing functions of inland wetlands using indices of RAM. So It is needed that consequent studies are to be performed with verifying the variables and indices.

  • Objectives : The aim of this review was to summarize and assess researches reporting thermal properties of moxibustion. Methods and Materials : We searched one electronic database(PubMed) and two journals(The Journal of Korean Medicine and The Journal of Korean Acupuncture & Moxibustion Society) and for the articles published until Nov. 2012. The articles reporting thermal characteristic of moxibustion were selected and reviewed. 31 articles were included and assessed in this review. The type of moxibustion, the material beneath moxbustion, main outcome and the amount of information were reviewed. The amount of information was defined as 1 for one main outcome reported in each article. Results : Direct moxibustion were used in 15 articles and indirect moxibustion were used in 19 articles. 11 researches used anti-heating plate for the material beneath moxibustion, one article used steel ring, agar with anti-heating plate, six articles used skin and another six articles used heater. Two articles used animals and another two articles used metals. The mean value of the amount of information was $4.41{\pm}2.94$(SD). Conclusions : Research articles assessing properties of moxibustion have been consistently published since 1993, and employed various methodologies. The amount of information has been associated with four section analysis and is currently decreasing. Research assessing properties of moxibustion with clinical effectiveness is needed.
