  • 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.

  • Serious games are selected by users according to the original goals such as education, treatment, training and so on. Therefore, those type of games are evaluated inside and outside the game about whether the goals are archived or not. Among quality test elements of serious game, assessment is about whether, in games, ability to verify goal achievement is included or not. In this paper, we examined the achievement-assessing function of serious game through several cases. Furthermore, to utilize for developing serious games for English learning, we designed a level system which achievement-assessing function is applied to. In this level system, we used 'competition and reward' as the core elements of game, and designed the system through simulation of which grades are level-designed along the user's English proficiency level based on notice of MEST(Ministry of Education, Science and Technology). This paper is expected to be useful reference for designing English learning game containing achievement assessing function.

  • For assessment of U-Eco City technologies, more concrete definition of those technologies are required. However, almost researches defined technologies as conceptually and even cannot include all of them. In this sense, the purpose of this study is to deduct assessing items for specifying applying priority of U-Eco City technologies. We performed the research by 3 steps. Firstly, we deduct assessing items of the technologies by researching their advance process. After then, we compensate the defect of those items through documentary research and made a periodic table about core technologies that can be useful for deducting long-term items. The assessing items what are deducted as a result of this study can be applied to the selection of technology, and will be useful to construct more objective and systematized U-Eco City. Furthermore, if assessment frame about technologies and services is developed from this research, it gives to us probability that standardized process of U-Eco City construction can be established.

  • 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.

  • The purpose of this study is to investigate expertise of mathematic teachers in development of designing assessment items, derived from development of assessing tools, which is a part of assessing competence of mathematic teachers. Analysis was made upon the difference between Pre-service and In-service teachers in terms of self-perception on assessment items. The assessing references of self-perception on developing in designing assessment items consist of followings: one's Beliefs and Self-Rating in designing assessment items. This investigation on self-perception was carried out by both pre-service teachers who are currently enrolled students in college and in-service teachers who are currently incumbent in secondary schools. This analysis based on 310 teachers' answers on self-perception of designing assessment items, both in- and preservice.

  • 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.
