The purpose of this research is to find out if it is possible to apply the Waldorf School's mathematics education method to Korean alternative schools which are run under the national curriculum. To achieve this, the researcher conducted class on geometry for three weeks with ten 7th graders(four girls and six boys) from Apple Tree Waldorf alternative school in Busan, which has adopted Valdorf education courses. For the first two weeks, the class was about 'fundamental geometrical construction', and then it was evaluated. On the third week, the lesson was on plane figures, followed by a test with 9 plane figure questions that are based on general middle school mathematics curriculum. The result shows that most of the students understood 'fundamental geometrical construction'. When it comes to the test on 'plane figures', seven students got 8 out of 9 right, two students got 6 out of 9 right, and one of them had difficulty solving the questions. According to the results of this research, it is thought that there will be no problem for students to understand mathematical concept even if the Waldorf School's mathematics education method is applied to Korean alternative schools. Also, the Waldorf School's mathematics education method is considered to be a good teaching model for the Korean mathematics curriculum which places emphasis on 'mathematical creativity' in regard to the curriculum and contents.

Coffee, which has spread from Ethiopia to Arabia, Europe and then to Korea, has become the most beloved beverage among today’s Korean people. After liberation, instant coffee was first introduced to Korea through the U.S. military, and coffee became popular in earnest. In the 1970s, Dongsuh Foods led localization of coffee by mass-producing instant and regular coffee, and in the 1990s, coffee shops replaced teahouses. After the 1997 financial crisis, office workers made coffee on their own as companies downsized on secretarial staff, leading to a further growth in instant coffee mix market. In 1999, the first foreign brand Starbucks was introduced to Korea and the culture of takeout espresso coffee took off. As consumers’ preferences of coffee constantly evolve, the demand for high-quality specialty coffee has emerged, individual roasters have grown in order to meet the demand, and a viral marketing through SNS has been used as a growth engine. In 2020, the spread of coronavirus(COVID-19) is affecting the global coffee market. As many offices, coffee shops, and restaurants practice social distancing, out-of-home sales such as coffee shops have decreased, whereas sales for a takeout coffee and home-café products have increased.

Thermal radiation pastes were prepared by dispersing carbon materials as fillers with a content of 1 weight percent in an acrylic resin. The kind of fillers was as follows; 25 μm graphite, 45 μm graphite, 15 μm carbon nanotube(CNT), a 1:1 mixture of 25 μm graphite and 15 μm CNT, and a 1:1 mixture of 45 μm graphite and 15 μm CNT. Thermal emissivity was measured as 0.890 for the samples with graphite only, 0.893 for that with CNT only, and 0.892 for those containing both. After coating prepared pastes on a side of 0.4 mm thick aluminium plate and placing the plate over an opening of a box maintained at 92℃ with the coated side out, the temperatures on the uncoated side of the plates were measured. The samples containing graphite and CNT showed the lowest temperatures. The paste with mixed fillers was coated on the back side of the PCB of an LED module and thermal analysis was carried out using Thermal Transient Tester (T3ster) in a still air box. The thermal resistance of the module with coated PCB was measured as 14.34 K/W whereas that with uncoated PCB was 15.02 K/W. The structure function analysis of T3ster data revealed that the difference between junction and ambient temperatures was 13.8℃ for the coated case and 18.0℃ for the uncoated. From the infrared images of heated LED modules, the hottest-spot temperature of the module with coated PCB was lower than that of the uncoated one for a given period of LED operation.

연구목적: 본 연구의 목적은 특수교사가 인식하고 있는 중도·중복장애학생의 정의를 분석하고 교육지원 요구를 탐색하는 것이다. 연구방법: 전국의 특수교사를 대상으로 지역별, 기관별로 층화추출표집하여 중도·중복장애 교육 전문성이 있는 교사를 대상으로 지도 학생을 기준으로 온라인 질문지에 무기명 응답하였다. 최종 254명의 교사, 557명의 학생에 대한 응답자료가 통계처리 되었다. 연구결과: 응답한 547명의 학생 중 중도장애 167명, 경도 중복장애 99명, 중도·중복장애 291명으로 나타났다. 주요 장애는 지적장애, 지체장애, 자폐성장애로 나타났으며, 중도·중복장애가 경도의 중복장애보다 장애 간 네트워크의 연결이 복합적인 것으로 분석되었다. 중도·중복장애로 인식하는 요인으로는 현재발달수준에서는 대운동기능, 시력, 청력이, 일상생활특성은 식사, 착탈의, 정서·행동특성에서는 우울증 및 조울증으로 나타났다. 중도·중복장애학생의 교육지원 중 필요한 지원에 대하여 특수교사들은 학급당 인원수 감축, 교사의 주당 수업시간 수 감축, 1:1 또는 2:1 집단구성을 통한 개별교육 시간 마련이 필요하다고 조사 되었다. 결론: 본 연구는 실제 현장의 특수교사를 대상으로 중도·중복장애에 대한 인식을 분석하고 필요한 교육지원을 탐색함으로써 향후 법적 근거를 마련하기 위한 기초 자료를 제공하였다.
