In this study, we want to analyze the aspect that required in the classroom for the operation of NCS-based curriculum, the interest of specialized subject teachers on implementable teaching and learning methods. As a result, the overall interest in teaching-learning method of specialized subject teachers was similar to that of non-user patterns among four types of interest patterns. In other words, specialized subject teachers want to know more about teaching-learning method for applying NCS-based curriculum, but we are only aware of the general facts at present, and it seems that there is low interest in actual operation. In addition, there was no statistically significant difference in the degree of interest in the teaching-learning method according to general variables(gender, related training experience, career, and curriculum group) of the specialized subject teachers. The specialized subject teachers are not well aware of the influence of the teaching-learning method according to the introduction of NCS-based curriculum, and to that end, there was little interest in collaboration with colleagues.

The purpose of this study is to conduct an exploratory investigation into Korean psychopathy by synthesizing the results of prior domestic research on the validation of psychopathy assessment tools. Domestic research on the validation of psychopathy scales has been constrained by limited research methodologies, bias toward male subjects, and the application of inappropriate factor structures. Furthermore, although discrepancies between the original scale and the Korean scale were identified regarding the factor structures through in construct validity research, discussion on the concept of Korean psychopathy has been limited. As a result, this study compared 16 domestic papers on the validation of psychopathy assessment tools along with 9 international foreign papers that addressed the factor structure of each original scale. By comparing the derived factor structures, items assigned to each factor, and omitted items from each study, the characteristics of Korean psychopathy were explored. The findings revealed that Korean psychopathy is recognizable from materialism, machiavellianism, and antisocial behavior and impulsivity. This study holds significance in synthesizing the outcomes of current domestic psychopathy validation research and offers a conceptual foundation to help understand Korean psychopathy.

CP(Counterpropagation)알고리즘은 서로 다른 두 개의 신경망이 하나로 결합 된 혼합형 모델로서, 다른 신경망 모델에 비해 비교적 단순하고 빠른 학습 속도를 보인다. 그러나 CP 알고리즘은 다양한 패턴이 입력되면 충분한 경쟁층의 수가 설정되지 않아 학습이 불안정하고, 출력층에서 연결강도를 조정할 때 일반적인 학습률 조정방법으로 불안정한 학습 결과를 보인다. 이러한 문제점을 해결하기 위해 다수의 경쟁층을 설정하여 경쟁층에서 패턴 분류의 정확성을 높이고, 입력 벡터와 승자 뉴런의 대표 벡터간의 차이와 승자 빈도수를 반영하여 학습률을 동적으로 조정하여 경쟁층에서의 학습이 안정적으로 진행되도록 하고, 출력층에서 연결강도를 조정할 때 모멘텀(momentum)학습법을 적용한 개선된 CP 알고리즘이 제안되었다. 본 논문에서는 개선된 CP 알고리즘에서 경쟁층의 수를 효율적으로 설정하기 위해 퍼지 제어 기법을 이용하여 경쟁층의 수를 결정하는 방법을 제안한다. 제안된 방법은 CP 알고리즘에 입력되는 패턴의 정보를 이용하여 퍼지 소속 함수를 설계하고 입력에 대한 소속도를 계산한 후, 퍼지 제어 규칙을 적용하고, Mamdani의 Min_Max 추론 방법으로 추론한다. 퍼지 추론을 통해 최종적으로 얻어진 값을 무게 중심법으로 비퍼지화 하여 최종적으로 개선된 CP 알고리즘의 경쟁층의 수를 결정하는데 적용한다. 제안된 방법의 학습 및 인식 성능을 평가하기 위해, 숫자, 영어 등과 같이 다양한 패턴을 실험에 적용한 결과, 제안된 방법이 경쟁층의 수를 결정하는데 효과적임을 확인할 수 있었다.

Purpose: Hospitals for patients and their guardians can, from the concept of healing, be removed from just gaining profits, but suggest a future-oriented direction for the hospital. Accordingly, there have been studies related to the selection of hospitals, but most were related to preference and satisfaction, and only recently did research from the concept of tradeoffs of factors for selection began to grow rapidly. Methods: From this context, this study evaluates the level of importance for factors of selecting hospitals using the analytical hierarchy process, and identifies the correlation with users, gender, age group, and outpatient features in order to identify the difference of awareness among different groups for selecting hospitals. In the factors for selection 26 factors in six categories were set through studies of preceding research, and after surveying 144 people, the following results were attained. Results: 1) The overall analysis results were found in the order of medical level, medical service, and fame, and low for facilities, which is similar to the cases of preceding studies. 2) For user analysis, it was similar between patients and guardians, but there was a slight difference in awareness among nurses, who are also medical service providers. Nurses showed relatively high level of importance in direct factors such as medical technologies and medical services, while guardians of patients showed higher importance in indirect factors such as facility environments and convenience. 3) Women showed higher assessments of importance levels in environmental factors, while men in physical factors. 4) The older the age group, the lower level importance there was on medical level, while the importance on fame reduced the further the commute to the hospital was.

In this study, we studied characteristics on human tactile perception according to the depth and the pitch of surface roughness. Three experiments were performed for this study. The first experiment was to arrange samples in the order of their roughness. The second experiment was to group samples according to their roughness. And, the third experiment was to subjectively evaluate the level of roughness for each sample using adjective scales. Through these experimental studies, we could verify that the depth and the pitch of surface roughness give a significant effect on tactile perception and the depth gives more significant effect than the pitch. So, the depth of surface roughness must be more importantly considered than the pitch in the tactile user interface design of product.

The purpose of this study was to analyse beginning science teachers' PCK. For the purpose of this study, two beginning science teachers were chosen in public middle school. Qualitative data were collected through classroom observation recording, semi-structured interviews, and other document data. Data were analysed using the constant comparative method. The results indicated that the two beginning science teachers' PCK had little differences; both have insufficient knowledge of science curriculum and assessment, and their PCK had quite differences in the instructional strategies and the orientations toward teaching science. Though they were aware of students' various levels, their common teaching method focused on delivery of science text knowledge for poor understanding about student. In conclusion, the two beginning teachers' PCK were still similar with preservice teachers. To develop beginning teachers' PCK, it needs to change the paradigm of pre-service teachers education program and to expand in-service teachers training and supporting program.

We proposed the device to control a computer with only a head and eye blinks so that disabilities by car accidents can use a computer. Because they have paralysis of their upper extremities such as C4~C5 paraplegics and cerebral palsy, they cannot efficiently access a general keyboard/mouse not using hands and foots. The cursor position was estimated from a gyro-sensor which can measure head movements, and the mouse event such as click/double click from opto-sensors which can detect eye blinks. The sensor was put on the proper goggle in order not to disturb the visual field. The performance of the proposed device was compared to a general optical mouse, and was used both relative and absolute coordinate in cursor positioning control. The recognition rate of click and double-click was 86% of the optical mouse, the speed of cursor movement by the proposed device was not much different from the mouse. The overall accuracy was 80%. Especially, the relative coordinate is more convenience and accuracy than the absolute coordinate, and can reduce the frequency of reset to prevent the accumulative error.

The purpose of this study is to investigate the effectiveness of education for information literacy by measuring information literacy of selected experimental group and controlled group from university students. Information literacy of each group was measured through structured questionnaires before and after taking the instruction course. The result showed there was a significant difference between two groups after the instruction. and the effectiveness of information literacy showed especially high in the area of information ethics and information analysis. It was also revealed that the education for information literacy is not affected by basic environmental factors at all. Also. students taken the course showed strong self-confidence and positive recognition in information literacy and library use, thus proved that education of information literacy is highly effective both in cognitive and attitudinal side for university students as a liberal arts course.
