창의력과 문제해결능력을 갖춘 인재양성에 대한 사회적 요구가 커지면서 체계적인 문제해결 방법론인트리즈에 대한 교육적 관심이 높아지고 있다. 본 연구에서는 대학수준의 공학과 예술의 융합교육분야에서 트리즈의 활용이 교육의 성과에 어떠한 영향을 미치는지 검증해 보고자 한다. 또한 이와 같은 과정에서 예술대학 학생들이 트리즈를 적용하여 과제를 수행할 때 어려운 점이 무엇인지 분석해 보고자 한다. 본 연구의 목적을 달성하기 위해 트리즈 이론 전반과 신제품개발 과정에 대해 문헌연구를 수행하였고, 교수-학습안을 토대로 실제 수업에 적용하였다. 또한 학생들의 트리즈 교육 전후의 인지도 변화, 과제 수행을 통한 트리즈 교육의 효과 및 애로사항 분석 등을 위해 조사연구를 수행하였다. 연구의 목적을 달성하기 위해 경기도 소재 예술대학 2학년 학생들의 ‘제품인터페이스’ 전공 수업에서 트리즈를 적용하여 신제품개발 절차를 경험하도록 하고 이를 통해 제품개발의 개념 설계 단계까지 수행하였다. 실제수업을 끝까지 이수한 학생들은 18명으로 2인 1조로 과제를 수행하도록 하였다. 학생들은 문제선정, 문제분석, 문제해결을 위한 트리즈 도구 활용 및 최종안 도출 등 트리즈 방법론을 적용하여 과제를 수행하였다. 연구결과 학생들은 트리즈를 적용하여 문제를 체계적으로 해결하는 능력, 문제분석 및 심리적 관성의 배제, 문제해결에 대한 자신감 등을 얻는데 효과가 있었던 것으로 나타났지만, 비공과대학 학생들에게는 개념적으로 낯선 용어와 기술적 지식의 부족으로 수업을 따라가는데 어려움이 있었다. 이와 같은 연구결과로부터 트리즈를 몰랐던 예술대학 학생들도 트리즈의 학습을 통해 아이디어 창출및 해결안 도출 과정에서 유의미하게 전공 분야의 작품 활동에 적용할 수 있다는 가능성과 함께 한 학기라는 한정된 시간 내 학생들이 보다 쉽게 이해할 수 있는 전략 개발의 필요성을 확인할 수 있었다. Educational interests have been focused on the systematic innovation tools, such as TRIZ, as the social needs for students with creativity and ability of problem solving ever increased. The purpose of this study is to present a case study of applying TRIZ into convergence education of art and engineering on university level and evaluate the educational effects. Also difficulties for the students in implementing TRIZ into their projects are investigated. Literature review was performed on the theoretical aspects of TRIZ and the processes of NPD(New Product Development). Instruction plan was developed and used in the course of one semester. The change of recognition level, the effectiveness of TRIZ on teaching and difficulties through projects are investigated. Sophomore students in an art college in Kyeong-Gi province practiced TRIZ in the ‘Product Interface’ course and produced concept designs following the new product development procedures. Eighteen students finished projects making two students teams. Students used the main TRIZ tools for selection, analysis, and finding solution of problems. The results show that students have gained improvement in systematic solution of problems, analysis of problems, eliminating psychological inertia and confidence in finding solutions. But it was shown that some students with non-engineering background had certain difficulties in following course due to unfamiliar terms and lack of knowledge in technology itself. As conclusions from this study, the possibility of applying TRIZ into courses of art college useful in the processes of idea generation and finding solutions was confirmed. At the same time, need of good strategic curriculum development to make students understand and fluently use TRIZ in such a limited semester was identified.

This study analyzed the contents of articles related on family lifes in Kwangju and Chonnam daily newspapers during the last year. In this study, articles were classified by the theme categories, publishing company, season, nature of messages, and academic diagnosis(nature). Through the results of this study we can understand what were major issues and concerns related family life lately, and that they suggested to take in Home Economics as a practical science. According to references on classification of home economics and a caption or content of articles the identified 890 articles were categorized into nine theme categories : family ethics, work and time, consumer, household economy, family(including child), housing, clothing, dietary food, health and hygiene. The results show that the numbers of each theme category were ranked as follows : (1) consumer(164) (2) dietary food(154) (3) family(136) (4) housing (129) (5) health and hygiene(84) (6) household economy(79) (7) clothing(65) (8) work and time(47) (9) family ethics(28) As for the subcategories of each theme category, in family ethics area articles related to ethic, consciousness, attitude, and value were reported the most frequently. In work and time, lost of articles related to leisure and service. In consumer, most of articles related to consumer information about goods & service. In household economy, many articles related to financial(banking) information. In family, child-related articles. In clothing, dress design and aesthetics. In dietary food, food purchase and management. In health and hygiene, articles about causes and symptoms of various disease and medical treatment were treated more frequently. According to publishing companies, Kwangju ilbo took more than Chonnam ilbo, but there was no great differences between the two. Also there was no great difference among frequency of articles by four season, but in winter articles on family lifes were written more frequently and in summer, the least. The numbers of informative articles were more than that of directive articles. In the side of the academic nature of message source, the numbers of non-academic articles were much more than that of academic articles.

The purpose of this study was to collect basic data for the development of oral health education program of parents and to encourage their actual interest and participation in school oral health program. The authors surveyed parents' awareness and behaviors about the oral health of their children. The subjects in this study were 193 parents of elementary school children in Seoul. The collected data were analyzed, the obtained results were as follows: 1. Thirty-five percent of the parents investigated paid a regular visit to a dental clinic. The must common tooth brushing time among them was after dinner, the second was after breakfast, and this was followed by before bedtime and before breakfast. 2. Ninety-four percent of the parents responded that prevention is necessary, 92.2% had a plan to visit a dental clinic to prevent dental caries, and 60.1% experienced receiving pit and fissure sealants. Ninety-seven percent responded that they did check their children's dental caries. 54.9% chocked their children's oral status after tooth brushing. The parents who visit a dental clinic on a regular basis were more likely to check their children's teeth after tooth brushing than those who don't(P<0.05). 3. Eighty eight percent of respondents wanted to keep the fluoride mouth rinse program. 4. It is recommended that an oral health education program be developed for parents to visit dental clinics on a regular basis, to educate as to the right tooth brushing time, and to check out their children's oral status after tooth blushing.

The purpose of this study was to collect basic data for the development of effective oral health education program in elementary school. The subjects in this study were 604 fourth-year, fifth-year and sixth-year students of an elementary school in Seoul. Oral health awareness and behaviors were surveyed and analyzed. The findings of this study were as follows: 1. The most common time for toothbrushing was after dinner(62.0%) and before bedtime(62.3%). By school year, the largest number who brushed their teeth after dinner were fourth and fifth graders while the greatest number who did so after breakfast were sixth graders Seventy-four percent of respondents brushed the teeth twice or more a day. By school year, the fifth-year students brushed their teeth the least while girls outperformed the boys in daily toothbrushing frequency(p<0.05). Regarding the intake of cariogenic food, 62.1% took that kind of food once or more a day. By school year, the fifth graders took the most (p<0.05), and girls took more cariogenic food than the boys(p<0.05). 2. Ninety percent of the respondents had visited a dental clinic. By grade, the sixth-year students had visited a dental clinic more frequently and girls more frequently than boys. Eighty percent of the respondents visited a dental clinic to receive treatment but just 12.3% visited a dental clinic to prevent oral diseases. Concerning the fetor of dental treatment only 14.4% expressed fear. School year made no difference, yet the percentage of girls who experienced fear was higher than that of boys(P<0.05). Regarding preventive treatment, 39.7% experienced pit and fissure sealing and 24.2% experienced the application of fluorides. All the students hadn't much experience in preventive treatment regardless of school year -- gender didn't make a difference. 3. Fourty-six percent of respondents had a preference for the fluoride mouth rinsing program; 38.4% wanted that grogram to continue. As to the reason for preference, 38.2% preferred it because of the prevention of dental caries, 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do(some of the respondents gave two different answers). 4. Despite an increase in the frequency of toothbrushing at the right time, they still took cariogenic food frequently Their visit to a dental clinics also aimed at treatment more than at prevention, and they had very narrow experience of preventive treatment. Furthermore, the fluoride mouth rinsing program failed to draw their interest. Therefore, it is recommended that a successful real health education program should be developed.

Kyeong-Eun Han(Kyeong-Eun Han),Ji Wook Youn(Ji Wook Youn),Jongtae Song(Jongtae Song),Dae-Ub Kim(Dae-Ub Kim),Joon Ki Lee(Joon Ki Lee) 한국전자통신연구원 2022 ETRI Journal Vol.44 No.6

In this paper, we propose novel disaggregated memory module (dMM) architecture and memory access control schemes to solve the collision and contention problems of memory disaggregation, reducing the average memory access time to less than 1 μs. In the schemes, the distributed scheduler in each dMM determines the order of memory read/write access based on delay-sensitive priority requests in the disaggregated memory access frame (dMAF). We used the memory-intensive first (MIF) algorithm and priority-based MIF (p-MIF) algorithm that prioritize delay-sensitive and/or memory-intensive (MI) traffic over CPU-intensive (CI) traffic. We evaluated the performance of the proposed schemes through simulation using OPNET and hardware implementation. Our results showed that when the offered load was below 0.7 and the payload of dMAF was 256 bytes, the average round trip time (RTT) was the lowest, ~0.676 μs. The dMM scheduling algorithms, MIF and p-MIF, achieved delay less than 1 μs for all MI traffic with less than 10% of transmission overhead.
