글로벌화라는 세계적인 흐름 속에 각국의 도시들은 각 도시의 인지도와 이미지를 제고시키기 위해 도시경관의 정체성을 확립하고자 노력을 기울이고 있으며 이러한 흐름 속에 서울도 도시경관의 정체성을 확보하기 위한 다양한 연구가 진행되고 있다. 그러나 일부 도시경관의 문제점 파악과 그 개선방향에 대한 연구가 주류를 이루고 있어 현재 구축된 도시경관 자체의 정체성을 확보하는 연구는 아직 미진한 실정이다. 이에 본 연구에서는 인터넷 설문조사를 수행하여 인지도 및 인식 차이를 기반으로 도시경관을 분석하고 이를 시각화하는 분석틀을 제안한다. 본 분석틀의 가장 핵심이 되는 도시경관에 대한 인식 및 인지도 차이 분석은 설문조사의 응답에서 추출한 정답률과 명답률에 의해 이루어지며 시각화는 이들의 상관관계를 통해 도출되는 정확률을 도식화하는 방법으로 수행된다.

This study surveyed 171 police officers working in Jeollabuk-do to investigate their first aid knowledge and the need for education. The results showed that the correct answer rate for first aid knowledge among police officers was 75.61 points out of a possible 100 points. Additionally, 98.8% of respondents indicated a need for first aid training, expressing a preference for 2-hour sessions integrated with their work education. There was a statistically significant difference in the correct answer rate for first aid knowledge based on education level and experience in emergency situations, but no significant difference in the need for education was observed across respondents. The significance of this research lies in its provision of foundational data for first aid education among police officers, which can be instrumental in developing training programs and policies aimed at enhancing their first aid capabilities. Specifically, the study contributes to improving the effectiveness of police officers' responses in emergency situations by offering concrete suggestions on the content, method, and duration of first aid training. These findings underscore the necessity and importance of providing comprehensive and effective first aid training not only to police officers but to all first responders, emphasizing that such training is crucial for ensuring public safety.

Objectives: This study was conducted by clinical dentistry hygienists to develop knowledge measurement tools and evaluate knowledge necessary to cope with emergencies related to systemic diseases occurring in dentistry. Methods: Basic questions were developed on the six most frequently occurring diseases in the dental office: diabetes, syncope, respiratory disease, coronary artery disease, cerebrovascular disease, and epilepsy. Fifty-eight preliminary questions were composed in a survey format through expert validation. The survey was then conducted on 290 dental hygienists to verify the composition validity and reliability. Factor and reliability analyses were performed using the SPSS 23.0 program, and the correct answer rate for each question was calculated. Results: 49 items of a total of 13 factors were adopted as the final items for signs, symptoms, prevention and treatment of five diseases. The question with the highest percentage of correct answers for each question was "Slowly set up the unit chair when raising the patient"(97.9%) during the prevention of unconsciousness and question with the lowest correct answer rate was "soft substances such as cloth should be put in the mouth to prevent trauma while the seizure persists" (16.6%). Conclusions: A total of 49 questions have been developed as tools to measure the knowledge of dental hygienists' first aid related to systemic diseases and it is expected that related curriculum can be operated or evaluated by using them.

본 연구는 평면 도형의 도형 분류하기 과제를 제시할 때 길이와 각의 표기 여부가 도형의 개념 이해에 어떤 영향을 주는지 알아보는데 목적이 있다. 이를 위해, 초등학교 4학년 학생 33명을 대상으로 분류하기 과제 해결 과정을 Eye-tracker를 통해 녹화하고 정답률과 Gaze Duration을 중심으로 분석하였다. 그 결과, 이등변삼각형과 정삼각형의 분류하기에서는 길이를 제시하였을 때 정답률이 증가하고 Gaze Duration은 감소하였다. 예각삼각형과 둔각삼각형 과제에서도 직각을 표기했을 때 정답률이 증가하고 Gaze Duration이 감소하였다. 이러한 결과로 볼 때, 평면도형을 분류하는 과제를 제시할 때는 길이와 각을 표기하여 학생들이 어림하여 도형을 분류하기 보다는 도형의 개념 이해를 바탕으로 분류하는 것을 측정하는 데 초점을 두어야 할 것이다.

본 논문에서는 경제시계열 데이타중에 하나인 환율데이타(Yen/Dollar)의 장기기억성과 정답율을 조사했다. 통상 단기 기억성을 가진 대표적 모델 AR 모델로 부터 생성되는 시계열에는 두종류의 프랙탈차원이 존재하는 경우가 많다. 두차원으로 분리되는 샘플 간격을 $k^{crossover}$라고 한다면, 통계모델에서K < $k^{crossover}$일때의 프랙탈차원을 $D_1$, K > $k^{crossover}$일때의 프랙차원을 $D_2$라고 한다면 $ D_1이면서 $D_2\cong2$ 인 관계를 가진다. 그러나 일본경제평균등 실제의 시계열에서는 이것에 반대되는 결과가 나타났다. 그 한 예로써 환율데이타에서는 $D_1>D_2$라는 관계를 가진다는 것을 알았다. 이것은 데이타 사이의 시간 간격이 멀어지는데 오히려 상관은 강해지는 현상을 나타내는 것이다. 환율 시계열을 뉴럴네트워크를 이용해서 예측한 결과, 예측오차로부터 얻어진 지수(指數) $\beta$와 D가 프랙탈성질을 가진 비선형 모델로 부터 구한 관계식 $\beta$=2-2D을 정확히 만족 시키는 것을 확인했다. 그리고 프랙탈차원의 차이가 정답율에서도 나타남을 확인했다.

In spite of school science learning, the students' conceptions have not been changed easily. Therefore, to make students overcome their non scientific conceptions has been an important issue in science education. The purpose of this study was to identify the conceptions of students and teachers on the motion of the earth and the moon. The instrument was developed for estimating students' understandings of the concepts related to the motion of the earth and the moon. The validity of the instrument was examined by the specialists in Science Educator and Astronomer. At the same time, the two field trials had been executed, and the items were modified. Also, it consists of 12 items including 9 two-tier multiple choice items and 3 multiple choice items. The population of this study consists of 250 eighth-, 299 tenth-, 292 eleventh-grade students, 134 science teachers in secondary school. SPSS/PC+ was adopted for the statistical analysis. The type of misconceptions possessed students were as follows: 1) At 12:00 noon, the sun is directly overhead. 2) First quarter moon is a half of overall surface of the moon. 3) Air don't rotate with the earth surface because it keeps apart from the earth surface. 4) Summer is warmer than winter, because the earth is nearer from the sun in summer. 5) Whenever season is changed, the direction of rotation axis of the earth is changed. 6) The moon is the brightest at the position of new moon, because the distance between the moon and the sun is the shortest and the moon is received strongest sunlight. 7) The moon is not seen at the position of real full moon, because it is covered with shadow of the earth. 8) When the moon is not seen in the earth, sunlight is not reached at the moon. The major findings were as follows : 1) The middle school students had more misconceptions than those of high school students. And female students had more misconceptions than those of male ones. 2) The rate of correct answer and the type of conception in the tenth grade students were very similar with eleventh grade students. 3) The higher cognitive level, the better development of scientific conception and the less misconception. Also, the correlation coefficient between scientific conception score and GALT score was 0.57. 4) The students in scientific part had higher the rate of correct answer than those of students in human part and the former had less misconception than the latter. 5) The rate of correct answer about model and figure items was lower than descriptive ones, because they did not understand about figures itselves. These types of misconceptions will be used for science instruction and studies of other conceptions need.

Learning procedure in the neural network is updating of weights between neurons. Unadequate initial learning coefficient causes excessive iterations of learning process or incorrect learning results and degrades learning efficiency. In this paper, adaptive learning algorithm is proposed to increase the efficient in the learning algorithms of Kohonens Self-Organization Neural networks. The algorithm updates the weights adaptively when learning procedure runs. To prove the efficiency the algorithm is experimented to clustering of the random weight. The result shows improved learning rate about 42~55% ; less iteration counts with correct answer.
