Higher efficiency and effectiveness of Research & Development phases can be attained using advanced statistical methodologies. In this work statistical methodologies are combined with a deterministic approach to engineering design. In order to show the potentiality of such integration, a simple but effective example is presented. It concerns the problem of optimising the performances of a paper helicopter. The design of this simple device is not new in quality engineering literature and has been mainly used for educational purposes. Taking full advantage of fundamental engineering knowledge, an aerodynamic model is originally formulated in order to describe the flight of the helicopter. Screening experiments were necessary to get first estimates of model parameters. Subsequently, deterministic evaluations based on this model were necessary to set up further experimental phases needed to search (or a better design. Thanks to this integration of statistical and deterministic phases, a significant performance improvement is obtained. Moreover, the engineering knowledge かms out to be developed since an explanation of the “why” of better performances, although approximate, is achieved. The final design solution is robust in a broader sense, being both validated by experimental evidence and closely examined by engineering knowledge.

The ultimate goal of the present study is to establish the acoustical performance standards of classroom for the elderly who are incomplete hearing people. As a pilot survey, the present study was conducted to investigate the listening environment and the actual condition of speech perception performance of education facilities for elderly, Acoustic performances of two education facilities for elderly in Cheongju were measured and questionnaire survey was done to elderly people. Also, speech intelligibility tests were undertaken by Consonant Vowel Consonant (CVC) and Phonetically Balanced Words (PBW) methods. The questionnaire survey showed that the elderly were satisfied with the listening environment of the educational facilities in general. Also, it was found that acoustical performances satisfy with the acoustic criteria of general classrooms in Korea. However, the results of the speech intelligibility test showed that the scores of elderly were significantly lower than twenties with normal hearing. It was also revealed that the scores are reduced as the age increases. Thus, it was concluded that the acoustical performance standards of educational facilities for the normal hearing were not suitable for educational facilities for the elderly.

Recently, all of the world are facing with a serious environmental crisis of global warming due to excessive energy consumptions. The Korean Government, taking over 97% of dependence on foreign energy, has made various efforts on reducing energy and greenhouse gas emission under the motto of "Low-Carbon Green Growth". Since the building sector takes 24% of domestic energy consumption, many design standards and regulations on saving energy in new buildings have been established. However, applications of energy saving designs and techniques on the remodeling process at deteriorated buildings including educational ones have been lack. Under a situation where the number of deteriorated schools accounts for up to 50%, this paper evaluated the performances of factors for reducing energy at deteriorated middle school buildings through an energy simulation tool on a standard school model. As a result, among factors of insulation, window's SHGC, southern louver, indoor setup temperature, and system efficiency, all other factors except window's SHGC and southern louver proved contribute to reduce energy at deteriorated middle school buildings, compared with the baseline energy consumption.

The purpose of this research is to make a basic study of a small theater planned to be built on the university campus for the exclusive use of performing arts. For this, the documents and records of small theaters in Seoul was first reviewed. And then, some selected theaters among small theaters opened since 2000 was examined and analyzed by their blueprints, design maps and actual measurement on the spot. Since 1990s, the increase in per capital income, the advancement of culture and arts, and the accompanying increase in demand have prompted universities to open performing arts courses. Going beyond the concept of a multipurpose auditorium a space devoted to professional performances has been increasingly needed by many universities. Small theaters that have been the subjects of study have become extinct or changed for other uses due to the rapid changes in the performing environment. This research examined theaters that have opened since 2000 and analyzed the data on their stages and seats. This study is intended for providing preliminary data for building of a small theater on the university campus.

Peer assessment in educational setting, refers to activities in which students provide grades or comments on other students' accomplishments such as writing, presentation, or performances. In case of writing, peer assessment can allow instructors to give out more writing assignments, which were often avoided because of the burden of grading. Moreover, grading other students' writing can enhance learning by having students participate in the assessment process. This review will introduce major peer assessment systems and results from empirical studies on peer assessment, examine obstacles to its more wide-spread use, and discuss topics for further research. We hope this paper will facilitate further studies and use of peer assessment in actual educational settings, and eventually lead to many changes in assessment and teaching in Korea.
