현재 첨단기기를 활용한 많은 지능형 자동차 연구개발이 급속히 발전하고 있는 추세이다. 사전 기술은 운전자의 운전미숙 때문에 생긴 돌발 상황을 대처할 수 있는 기능을 갖춘 첨단 자동차 안전장치의 용도제한과 고비용으로 대중화 되지 못했다. 그러므로 안전장치의 개발은 미숙한 운전자들의 안전 운전을 위해 사각지대 감지 장치가 필요하다. 사각지대에 관련된 연구 동향으로써는 사각지대 거울에서부터 사각지대 충돌회피시스템 등 여러 가지의 특허들도 연구된 상태이다. 본 논문에서는 초음파센서와 서보모터 및 기타 LED장치를 사용하여 새로운 기술적 메커니즘을 제안했다. 사각지대를 감지하기 위한 초음파 센서의 적절한 위치를 설계하였고, 회로도를 설계하여 모형으로 사각지대 감지장치를 구성하였다. 성능을 검증하기 위한 실험에서는 이동하는 물체와 동일선상에서의 물체를 감지하는 두 가지 방법으로 사각지대 감지테스트를 완료 하였다.

연구는 다의어의 문맥통합과정에서 관찰되는 숙련독자와 미숙련독자간의 개인차가 숙련독자의 문맥의존적인 처리특성에서 비롯되는지를 살펴보고자 하였다. 숙련독자의 문맥의존적인 처리특성을 좀 더 직접적으로 검토하기 위해 검사단어 강제선택과제를 고안하여 일련의 실험을 수행하였다. 편중문맥을 사용한 실험 1에서 숙련독자는 다의어의 주도적 의미가 부적절 검사단어로 사용된 실험조건과 무관단어가 부적절 검사단어로 사용된 통제조건간의 선택반응시간에 차이가 없었다. 한편 적절검사단어 선택을 방해하도록 구성된 갈등문맥이 사용된 실험 2에서 숙련독자는 미숙련독자보다 선택반응 시간이 느려서, 숙련독자가 적절검사단어 선택과정에서 더욱 큰 간섭을 경험했음을 보여주었다. 전체적으로 실험의 결과들은 숙련독자의 다의어 처리 특성이 문맥의존적이라고 가정할 때 잘 설명될 수 있는 것으로 보여진다.

Purpose: The existing web sites for premature babies are operated by non professionals and thus do not provide any medical or professional information necessary for rearing premature babies. The purpose is to construct a new website with lots of medical and professional tips for premature babies. Methods: First, topics of discussions are collected from the bulletin boards of three websites, operated by non professionals, for premature babies. And new website for premature babies is constructed based on the identified topics and also based on professional consultation with six professors. Results: The newly constructed website provides professional tips for the above topics as well as introduction of it's object, general medical information and baby rearing information and the bulletin board for parents of premature babies. Conclusion: By providing professional tips for mothers of premature babies, the new website is expected to provide detailed, accurate and professional information on issues most parents of premature babies concern.

Purpose: This study was meta-analysis study that it was to analyze the effect of sensory stimulation on preterm infants. Method: The sample of this study is 18 researches of selected by criteria. The conclusion of study was that sensory stimulation of preterm infants is effective. Result: Most large effect size was Katz(1991)'s study(d=1.96), small effect size was Caine(1991), s(d=0.37). Especially multimodal sensory stimulation(d=1.2) was more effective than unimodal sensory stimulation(0.53). Also behavioral variable of preterm infans was most sensitivity indicator. Conclusion: According to the result, the study on sensory stimulation should be research according to the gestational age and birth weight of preterm infants. In addition, the feasible sensory intervention should be develop.

Purpose: The purpose of this study was to examine the effects of Kangaroo Care (KC) on physiological marker of preterm infant in neonatal intensive care unit (NICU). Methods: The research design was a nonequivalent control group pretest-posttest. Data were collected from July 1, 2007 to February 29, 2008. The participants were 26 people of experimental group and 27 people of control group. KC was applied three times per day, for a total ten times of 4 days to the experimental group. Results: There was significant difference between experimental and control groups on the skin temperature on of preterm infants. The skin temperature in the intervention group was significantly higher than in the control group. Conclusion: Kangaroo care can be applied as a supportive nursing intervention to preterm infant at neonatal intensive care unit.

Purpose: This study was conducted to assess the knowledge and performance of developmentally supportive positioning for premature infants (DSPP) among neonatal intensive care unit (NICU) nurses. Methods: The participants in this study were 131 nurses working in the NICU at five university hospitals in Daejeon and the city of Cheong-ju. The collected data were analyzed with descriptive statistics, the t-test, analysis of variance, and Pearson correlation coefficients using SPSS for Windows version 22.0. Results: NICU nurses' average DSPP knowledge score was 24.7 out of 33.0, and their average DSPP performance score was 3.2 out of 4.0. A statistically significant positive correlation was observed between knowledge and performance of DSPP (r=.32, p<.001). Conclusion: To improve the level of NICU nurses' knowledge and performance of DSPP, educational programs should be developed and their effectiveness should be verified.

Deletion of the short arm of chromosome 6 is relatively rare, with the characteristic features of craniofacial malformations, hypotonia, and defects of the heart and kidney, with hydrocephalus and eye abnormalities. Here author reports a premature girl with bilateral anophthalmia, bilateral hydrocephalus and marked hypotonia, whose chromosome analysis revealed a 46, XX, del(6)(p23) chromosome constitution.

The brassinosteroid-like active principles from immature seeds of Zea mays were purified and identified as castasterone, teasterone, 28-norcastasterone and 6-deoxocastasterone by GC-MS analysis. Our work is probably the first report that showed the presence of brassinosteroids in Zea mays seeds.

본 논문에서는 영어 회화 교육을 위한 예제 기반 대화 시스템에 대해 논한다. 기존의 획일적인 멀티미디어 영어 학습에서 벗어나 자연어 처리 및 대화 기술을 이용하여 지능적인 일대일 영어 회화 교육 제공을 목적으로 한다. 본 시스템은 미숙한 학습자 발화를 이해할 수 있으므로 불완전한 언어 구사 능력으로도 대화를 참여할 수 있는 체험형 학습을 제공한다. 이를 통해 학습자에게 영어를 배우려는 흥미로운 동기를 부여한다. 또한 학습자의 표현력 향상을 위한 교육적인 도움 기능을 갖추고 있다. 이를 위해 우리는 학습자의 미숙한 표현을 이해하는 통계 기반의 언어 이해 모듈, 도메인 확장성이 뛰어난 예제 기반 대화 관리 모듈, 교육 및 평가 기능을 개발하였다.

Purpose:　The purpose of this study is to identify how regular stimulation affects apnea of a premature infant. Method: This study was used a within-subjects design with repeated measure using GEE (General Estimating Equation) and had been conducted from July 1, 2003 to March 12, 2004. The subjects consisted of 11 apneic premature infants who had showed apnea more than twice for 12 hours. A regularly vibrating test lung was provided to the subjects to find how regular stimulation affects apnea. Result: From the result of regular stimulation for apneic premature infants, both the lowest SaO2 and the lowest heart rate at experimental period were found to be increased significantly. However, the decreased frequency of the apnea cases was not statistically effective. Conclusion: These findings indicate that regular stimulation for apneic premature infants could be effective on increasing both SaO2 and heart rate. Therefore, we suggest regular stimulation to be used clinically to heal apnea of premature infants.
