  • 본 연구에서는 국내 콘텐츠 생산 및 유통방식의 급격한 변화에 따른 방송장비 구매 수요처의 절대적인 장비구매 인식을 비교하였으며 이에 수요자가 지각하는 국산 방송장비의 기술 신뢰도, 시스템 안정성 등의 정보의 정도가 장비구매에 미치는 영향을 연구모델을 통해 분석하였다. 방송 장비 수요에 관한, 기존 연구 데이터의 미진함으로 인하여 방송장비 전문가들과의 심층인터뷰와 설문조사를 병행하였다. 분석 결과로 외산장비에 비해 국내 장비의 단품구매와 시스템, Block구매의 경우가 많아 호환 경쟁력이 미흡하고 기술발전이 늦다. 국내 방송장비수요처가 인식하고 있는 국산방송 장비에 대한 선호, 만족도의 향상을 기하기 위한 기술 신뢰도 증진과 핵심 주요장비의 개발이 시급하며 소출력 송신기 안테나, 모니터장비에 국한되어있는 국산 장비의 공급을 확장하기 위한 개발이 시급하고 해외진출과 시장을 확보하기 위한 국내육성 지원도 요구된다.

  • Halitosis, defined as an unpleasant oral odor, is a commonly experienced condition with a variety of etiological factors and may cause a significant social or psychological handicap to those suffering from it, In most cases, halitosis originates within the oral cavity itself and patients with periodontal disease often suffer from oral malodor, The most common cause of this disease is related to microbiota which reside on the tongue and in the periodontal pocket, This study was undertaken to examine the effect of full mouth disinfection including tongue scraping on oral malodor in a group of patients with chronic periodontitis, The relationship between halitosis and oral health status was also investigated, The volatile sulfur compounds (VSC) scores were significantly correlated with Plaque Index, Bleeding Index, pocket depth, and tongue coating score, The organoleptic ratings were significantly associated with Plaque Index, Bleeding Index. and tongue coating score, The VSC scores and organoleptic ratings correlated strongly with each other. Full mouth disinfection resulted in a significant reduction in the VSC scores. organoleptic ratings, and self-perception of malodor up to 12 weeks, This study indicates that in patients with chronic periodontitis. a full mouth disinfection including tongue scraping has a significant effect in the treatment of oral malodor.

  • 본 연구의 목적은 과학 영재들과 학부모, 영재 담당교사들이 창의 인성 교육에 대해 어떤 인식을 가지고 있는지를 알아보고, 이를 바탕으로 과학 영재들을 위한 창의 인성 교육의 방향을 탐색하는 것이다. 이를 위해 대학부설 영재교육원과 교육청 영재교육원에 재학 중인 학생들과 그 학부모, 영재담당 교사들을 대상으로 그룹 또는 개별 심층면담을 실시하였다. 연구결과 연구대상자들은 타인에 대한 배려와 봉사로 함께 어울릴 수 있는 인성, 과학적으로 뛰어난 역량과 사고 능력으로서의 창의성, 추진력과 설득력을 통한 리더십, 그리고 일관성 있는 행동과 실천력으로서의 도덕성을 미래 사회에 필요한 과학영재의 자질이라고 생각하고 있었다. 또한 이들은 영재교육과정 속에서 과학에 대해 마음껏 탐구하고 배우며, 리더로서의 가치관을 형성하고, 친구들과의 협동을 통해 새로운 산출물을 완성해내는 성취감을 얻을 수 있길 바라고 있었다. 이러한 연구결과를 토대로 창의 인성 중심의 과학영재교육은 다양한 과학적 체험과 탐구가 개별적이 아닌 협력적으로 이루어져 완성됨으로써 상호관계 속에서 미래 사회에 요구되는 자질을 키우고 과학영재로서의 성취감을 느낄 수 있게 이루어질 필요가 있음을 제언하였다.

  • Purpose: The purpose of this study was to investigate issues and needs related to child health management as recognized by teachers in day care centers. Methods: Data were collected from 130 teachers from 20 day care centers. Each teacher was interviewed in depth and the data were examined through content analysis. Results: For issues on child health management, the analysis scheme consisted of 10 categories and 36 subcategories. For needs on child health management, the analysis scheme consisted of 10 categories and 37 subcategories. Teachers indicated that tools for physical examination and playgrounds were insufficient and they had difficulty in controlling attendance of infectious children. They also indicated the lack of a linkage between day care centers and hospitals, lack of knowledge of health management, high teacher versus child ratio, and lack of help and budget needed for health care. Conclusion: The results of this study suggest the need to develop a linkage between day care centers and medical institutions. Also there is a need to provide support from health care personnel, health education for teacher, health management manuals for teachers, and financial aid to satisfy the needs for health management in day care center for children.

  • This study aimed to investigate the perception, consumption, and acceptability of convenience mealsin low-income female elderly attending a lunch program at a community well fare center. Using in-depth interviews, qualitative data were collected 11 elderly females ($62.5{\pm}11.2y$) living in Seoul. Participants tried to eat various foods in small-portionsat home, although they ate out what they were offered. Elderly females preferred lunch box-type meals containing a bowl of rice served with toppings, gruel, or Bibimbop due to the growing unavailability of cooking or preparing a meal. Side-dish type convenience mealswere also preferred among elderly females since boiled rice can be easily prepared according to individual preferences. In addition, participants preferred healthy foods. Convenience meal planning and production, appropriate kinds of foods, cooking methods, menus, and packaging should be selected based on the elderly's functional atrophy in chewing, swallowing, digestion, and metabolic diseases. Furthermore, food preferences and comfort foods among the elderlyneed to be identified and characterized. Therefore, more information, including bite size, cutting size, and food texture, should be provided to understand and develop convenience meals for the elderly.

  • The purpose of this study was to investigate the interaction of science PCK between two elementary school teachers by the teacher collaboration within the school. We chose the case that two teachers collaborated spontaneously in the 5th-grade science classes. Even though they had similar teaching experiences, one of them had the science PCK while the other did not. As a result of this study, two teachers began to collaborate to avoid comparisons of science classes between them. They shared the same teaching plan but practiced science teaching individually. During they taught science, they usually collaborated on the instructional sequences, student's activities, and the content of assessments. They had an in-depth collaboration when the teacher who lacked the science PCK asked help to teach problem-centered learning by science inquiry. During the collaboration, their science PCK components, especially the knowledge of instructional strategies for teaching science, shared and it affected the teacher's science practices who lacked the science PCK. However, they did not usually share the knowledge of teaching for their everyday science classes because two teachers had the perception of noninterference about their science classes. This case has the limitation that it is hard to generalize the results but teacher collaboration shows the possibility to develop the elementary school teachers' science professionalism by having peers in the school who can help them in science classes.

  • 최근 국내 건설산업은 성장의 시기를 지나 침체기로 접어들고 있으며 경쟁력 향상을 위해 건설사업관리 특히 공정관리의 중요성이 더욱 부각되고 있다. 이러한 상황에 토목 건설업계는 생존을 위한 다양한 공사관리 방안의 연구 및 현장 적용에 부단한 노력을 하고 있으며 많은 성과를 이루고 있으나 아직도 체계적이며 효율적이고 현장 활용도가 높은 공정관리 기법의 정착은 이루어지지 못하고 있다. 이에 본 연구에서는 공사관리의 핵심인 공정관리의 활용에 대해 설문조사방식으로 현장기술자들의 인식 및 이해의 정도를 파악하며 현장에서 실제 사용하고 있는 공정표의 작성수준과 활용 현황을 파악을 위해 방문 조사하여 현재 국내 공정관리 현주소 및 문제점을 파악하였다. 아울러, 기존문헌 및 연구논문의 고찰, 현장에의 적용성을 바탕으로 현장 활용성이 높은 WBS 분류에서부터 work pacckage 도출과 Activty도출, 공정표 작성 및 관리방안을 제안하였다.

  • The purpose of this study is to find out the practical problems that 6th grade students are facing, how they perceive Practical Arts education and the praxis of Practical Arts education relating to the problems, and whether the content of Practical Arts curriculum is useful for solving practical problems of 6th grade students. The data used in this study are collected from questionnaires and include in-depth interviews in order to make up for the quantitative research. The major findings of this study were summarized as follows. 1. Elementary school students regarded Practical Arts education as the subject matter through which they learn skills of life. They thought it is useful to their present and future life and to nurture environment-friendly attitude. Furthermore, elementary school students perceive that the meaning of practice in Practical Arts education lies not in praxis as practical action, but in just practice as technical action. 2. According to the survey based on their perception and their practical problems, 66.9% of students answered the learning content of Practical Arts education is not useful in solving their problems. And only 33.4% of students answered the learning content of Practical Arts education is useful in solving their problems. Negative view was predominant among elementary school students. And the Practical Arts curriculum does not reflect much of the practical problems that 6th grade students face. Through these results, Practical Arts education turns out to be hardly related with students' life, though it is the subject matter of students' real life.
