  • 초등학교 학교급식 조리사를 대상으로 초등학생들에게 적합한 품목별 식재료의 크기에 대한 설문조사를 실시한 결과, 응답자의 대부분이 일반 성인식으로 제공되는 크기보다 3/4(0.75배) 또는 2/4 정도 작게 제공하는 것이 적당하다고 응답하였다. 식재료 규격을 설정하고 실제로 현장에 적용하는 실험은 사진자료를 이용한 조사, 실제섭취량 조사 등 2가지 방법으로 초등학교에 6개교에서 학령별로 실시하였으며 전체적으로 크기에 따라 학생들의 실제 섭취량과 선호도가 달라지는 것으로 나타났다. 이들 결과에 따라 식단별 식재료 규격을 3종류로 구분하고 크기가 표시된 흰색 아크릴판(가로${\times}$세로, $290{\times}210\;mm$)을 이용하여 식단별 연령별로 적합한 식재료크기를 설정하였으며 실제크기와 대조하여 사진자료로 작성하였다. 이들 자료를 다시 식단별로 분류하여 식재료 품목별 커팅 크기와 코드를 설정하였으며 설정된 식재료는 품목별로 나물 12종, 야채 15종, 김치 9종, 젓갈 2종, 튀김 8종, 육류 5종, 어류 19종, 건어물 5종로 최종결과는 책자로 제작이 가능하도록 편집전문가를 통한 수정작업으로 완성시켰다.

  • PURPOSE. To improve the clinical effects of complete denture use and simplify its clinical application, a digital complete denture restoration workflow (Functional Suitable Digital Complete Denture System, FSD) was proposed and preliminary clinical evaluation was done. MATERIALS AND METHODS. Forty edentulous patients were enrolled, of which half were treated by a prosthodontic chief physician, and the others were treated by a postgraduate student. Based on the primary impression and jaw relation obtained at the first visit, diagnostic denture was designed and printed to create a definitive impression, jaw relation, and esthetic confirmation at the second visit. A redesigned complete denture was printed as a mold to fabricate final denture that was delivered at the third visit. To evaluate accuracy of impression made by diagnostic denture, the final denture was used as a tray to make impression, and 3D comparison was used to analyze their difference. To evaluate the clinical effect of FSD, visual analogue scores (VAS) were determined by both dentists and patients. RESULTS. Two visits were reduced before denture delivery. The RMS values of 3D comparison between the impression made via diagnostic dentures and the final dentures were 0.165 ± 0.033 mm in the upper jaw and 0.139 ± 0.031 mm in the lower jaw. VAS ratings were between 8.5 and 9.6 in the chief physician group, while 7.7 and 9.5 in the student group; there was no statistical difference between the two groups. CONCLUSION. FSD can simplify the complete denture restoration process and reduce the number of visits. The accuracy of impressions made by diagnostic dentures was acceptable in clinic. The VASs of both dentists and patients were satisfied.

  • In this study, the contents of elementary school science textbooks related to 'heat and temperature' are analyzed and alternative conceptions ofi"heat and temperature" among students enrolled in grades 4, 5 and 6 are investigated. 259 students were selected from a elementary school located in urban area. The relationships between students' alternative conceptions and the content of elementary science textbooks are also examined. Students' conceptions are analyzed from their answers to a paper-and-pencil test. The typical alternative conception of "heat and temperature" held by students was follows. They think that "heat" is a material and "temperature" is value of heat amount. They can't distinguish between "heat" and "temperature". Their explanation of "heat and temperature" is focused on hot or cool sensation and other observable characteristics of a material. A textbook analysis indicated that contents on "heat and temperature" were organized without the viewpoint of particle motion theory. This may be one of the causes of students' alternative conceptions.

  • The purpose of this study was to understand the preferences of the uniform design for the preschool student's parents. 97 parents became subjects for the research and questionaries were analysed by distribution of frequency and percentage using SPSS V. 18.0. The results of this study could be summarized as followings. First, most of the parents preferred to wearing preschool uniform and expected further improvement in function, material and design. Second, the preferred form was semi formal style consisting of shirt, knit vest, knit cardigan, and coat. Third, the preferred colors were the mixing together bright colors and quiet colors in vivid and pastel tone. Fourth, functional materials to comfort in children's physical activities and to serve convenience in cleaning were preferred. In Conclusion, the preferred design characteristics were combined function to enhance comfort and convenience in children's physical activities with esthetics to present loveliness and modesty as preschool students.

  • Colleges of technology in Japan are characterized by specialized education starting from the first grades aged fifteen, making it particularly important to provide motivation for specialized subjects. The most difficult thing for teachers in the technical college is giving the motivation to a professional education to the lower grades who don't know the technology and engineering. Teachers tried to use and make a suitable example or an education material for their lecture. The generation gap with students makes it difficult for teachers to use examples of objects that students are actually familiar with in their daily life. To compensate for the generation gap with students, we asserted that education for lower grades should adopt the perspectives of students in higher grades. The relative closeness in age of lower and higher grades helps reduce the generation gap with students, which is advantageous in that teachers can share the perspectives of students.

  • 본 연구는 고등학교 수학 문제의 난이도 예측에 있어 객관적인 방법이 아닌 주관적인 방법으로 예측할 수 있는 변인을 찾아보며 동시에 문제를 푸는 학생 개개인이 느끼는 어려움이 어떤 변인에 의해 주로 결정되는가를 살펴봄으로써 개별 문항에 대한 정답자의 비율을 살펴보는 정량적인 방법으로 분석되는 난이도를 문제를 푸는 학생 개인이 느끼는 난이도의 측면에서 분석해보고자 하였다. 고등학교 3학년 학생 6명을 2명 또는 3명의 팀으로 편성하여 3월에서 5월까지 3개월간 총 11회에 걸쳐 문제풀이 과정을 관찰하고 반구조화된 면담을 통해 학생 개개인이 느끼는 곤란함이 어떤 요인에 의한 것인가를 분석하여, 문항의 난이도는 내용 제재의 생소성, 행동영역, 문형, 문제의 복잡도 등의 요인에 의해 결정됨을 알 수 있었다.

  • This study is intended to propose the new design course on Contemporary folk Hanbok by researching their preference to Contemporary folk Hanbok. To do so, the definition of styles, preference in details and fitness for the occasion to wear Contemporary folk Hanbok were evaluated and analyzed. The collected materials were investigated in quality and content. As for the data, five Contemporary folk Hanbok brands, in the city were selected and twenty styles from catalog were extracted. The subjected of study were 219 university students living in Seoul and Kwang-ju, Mok-po. they answered the questionnaires, the results of study were following: 1) In style of Contemporary folk Hanbok, there were positive support on longer Jeogori than traditional one and a seamless one-piece skirt at the length of ankle. But they had the negative thought of various spapes shapes related to the styles of Contemporary folk Hanbok. 2) In a view point of coloring on women's Contemporary folk Hanbok, the student supported the saturation more than special preference to similarity or contrast harmony. Students liked the harmony of achromatic colors or same colors up and down which are not traditional 3) In men's Contemporary folk Hanbok, students were for the harmony of same colors in up and down, preferring wool/polyester to cotton or silk100% (traditional materials) in materials 4) It indicates that what students thought generally of the occasional appropriateness of Contemporary folk Hanbok didn't match with the choice of proper occasion on preferred style. The western clothes have difference in design, material, color and manners of co-ordination related to ordinary cloths and out wear, but Contemporary folk Hanbok don't have these difference. Therefore, it is needed to develop the expensive designs discriminated between ordinary clothes and out wear in design, material, color and co-ordination corresponding to the every day life style.
