본 논문에서는 개체명 인식과 언어 모델의 다중 학습을 이용한 한국어 개체명 인식 방법을 제안한다. 다중 학습은 1 개의 모델에서 2 개 이상의 작업을 동시에 분석하여 성능 향상을 기대할 수 있는 방법이지만, 이를 적용하기 위해서 말뭉치에 각 작업에 해당하는 태그가 부착되어야 하는 문제가 있다. 본 논문에서는 추가적인 태그 부착 없이 정보를 획득할 수 있는 언어 모델을 개체명 인식 작업과 결합하여 성능 향상을 이루고자 한다. 또한 단순한 형태소 입력의 한계를 극복하기 위해 입력 표상을 자소 및 형태소 품사의 임베딩으로 확장하였다. 기계 학습 방법은 순차적 레이블링에서 높은 성능을 제공하는 Bi-directional LSTM CRF 모델을 사용하였고, 실험 결과 언어 모델이 개체명 인식의 오류를 효과적으로 개선함을 확인하였다.

This study attempted to understand the characteristics of pedagogic activities performed by pre-service elementary school teachers. To this end, it applied Algodoo simulations to analyze the actions of students and obtain educational implications for optical learning. The study's participants comprised 79 first-year students enrolled in a teacher training college. Their activities could be classified as representation reproductions, verification experiments, and inquiry experiments. Students who performed representation reproduction exercises replicated renowned and authoritative exemplars, apprehending and demonstrating their principal features through simulations. Students performing verification experiments attempted to validate previously learned optical concepts by reviewing the relevant theoretical contexts. Such students primarily conducted simple experiments. Students accomplishing inquiry experiments used simulations to explore phenomena they did not know. Some of them even investigated optical phenomena beyond the domain of general physics. The above results confirmed that free optical experiments performed using Algodoo can effectively denote starting points for learners to engage in activities at varying levels. Additionally, students require assistance from instructors in addressing queries about the application of the principles and models related to optics. This study suggests ways in which instructors should help students at each level of activity. Additionally, the paper presents examples of varying levels of inquiry-related activities available on Algodoo. It also discusses the advantages and disadvantages of performing inquiry-based activities on Algodoo and suggests ways of enhancing the learning achieved through this platform.

This paper portrays software reuse as analogical mapping and rule development.In order to explore the impacts of inconsistent representationS on the cognitive process of software resuse,it manipulates the intermal representations of source and target problems and their program solutions.The experimental design for this study has two factors:1)the degree of structural consistency between the source problem and the target problem,and2) the degree of structural consistency between the source problem and the source solution.A full-scale protocol analysis reveals that these two factors influence the cognitive process of mapping between source and target,the process of developing rules,and the interrelation between analogical mapping and rule development.The paper concludes by discussing the implications of these results for software reuse.

This study is a research synthesis analyzing how field geology education is conducted in domestic and foreign countries in the recent 20 years and how it reflects the characteristics of authentic geologic inquiry. For these purposes, we first drew five elements of inquiry in field geology (observation, representation, abductive reasoning, spatial thinking, and diachronic thinking) considering the field geologists' actual research method as well as its pedagogical significance in science education. We developed analysis criteria for field geology education. The 53 cases were analyzed based on each element of inquiry in field geology and its sub-elements, and also the tendency of overall elements. As a result, observation and representation were included in most cases, but there appeared less frequency in order of abductive reasoning, spatial thinking, and diachronic thinking. For observation, the ratio of purposive observation and autonomous observation is high. For representation, both visualizing and linguistic type of representation and free-form representation appear frequently. For abductive reasoning, the step of generating hypothesis is often included and the hypothesis tends to be about the geological formatting process. For spatial thinking, type of self-location and perception of the spatial configuration of the structure appear at a high rate. For diachronic thinking, type of stratigraphic sequence is the most frequent. The proportions of the cases including three or more elements of inquiry in field geology consist 87% of the total. We suggested implications for improving geological fieldwork as authentic science inquiry in the future.

Leo Kanner (1943)의 자폐증에 관한 획기적 논문발표 50주년을 맞아, 자폐증의 개념변천, 분류, 의학, 원인설 및 자폐증의 본질을 문헌고찰을 통해 살펴 보았다. 초기에 자폐증을 정신병의 아형으로 보다가 1980년 (DMS-III)을 기점으로 전반적 발달장애로의 개념 변천이 일어났다 원인설도, 초기의 심리${\cdot}$환경설은 지지 받지 못하고 1960년대에는 신경${\cdot}$생물학적 이상이 자폐병리의 기저를 이룸이 분명해 졌고 1970년대에는 지각과 운동, 감각과 인지 통합의 결함, 심각한 언어, 인지의 장해가 일차적인 결함으로 생각 되었다 최근 1980년 후반기 부터 상징적${\cdot}$표상적 인지의 결함, 타인의 감정과 생각의 이해 결함, 사회적${\cdot}$정감적 표현의 결함등 사회${\cdot}$정서발달의 이상이 자폐의 근본적 결함이라는 비교 관찰 연구가 많이 보고되어, 자폐증의 근본적이고 일차적인 결함이 정감적 접촉의 선천적 장애라는 Kanner의 놀라운 임상적 통찰을 증명해 주고 있다. 저자는 이상의 광범위한 문헌 고찰을 통해 자폐장애를 일차성 애착장애로 개념화하고 앞으로 치료, 교육의 방향도 일차적으로 사회${\cdot}$정서발달에 촛점을 두어야 하며, 특히 어머니와의 애착증진 치료가 필요함을 제안하고 있다.

Many contemporary architectural avant gardes tend to use painting as a medium to create architecture which goes beyond the rationalized spatial conception of modem architecture represented by perspectivism. They produce non perspective drawings to represent spatial Ideas, and expand it through poetic imagination to create an unexpected architectural form and space. This paper attempts to analyze the historical origin and background of dominance of drawing in the production of architecture. It was with the invention of perspective that architectural representation became important tool for architectural production. Thereafter, drawing was considered prior to actual building and architecture was considered a three dimensional realization of two dimensional drawing. Modernist avant gardes such as Cubism shattered the rationalized pictorial space of perspective and found a new pictorial space. They tried to extend it to three dimensional space through parallel projection largely based on the Hildebrand's theory of pure visibility. However, due to the ambiguity of the position of the viewing subject, their attempts could not succeed in creating a new architecture. The new architectural avant garde of the 70's rediscovered the early 20th century avant gardes in their attempt to create a new architecture which can register the fragmented spatial condition of contemporary society, and used painting as a medium to create architecture. Their difference from the early avant gardes was that they used poetic imagination rather than parallel projection in the process of projecting three dimensional space and form from the painting. However, their architecture cannot escape the scopic field of perspectivism in that they rely on the picture plane and the distance between object and viewing subject. Therefore, I conclude that in order to create architecture which goes beyond the rationalized space of modern architecture, it is necessary to resort to other tradition of modern architecture than visual one.

As standardized test and current perfomance assessment have some problems in the aspects of contextuality, authenticity and intelligence faimess, the aim of this study is to propose an 'intelligence-fair and authentic assessment(IFAA)as an appropriate altemative and to make sure of the probability of its application. In geographical education, an idealistic assessment can be realized when the tasks bear authenticity, multiple intelligence of students are accepted and the objective are confirming with general purpose. IFAA model consists of 5 elements. They are the selecting for strategic ideas, the developing a real-life task, the constructive instructing with teacher, the offering opportunity of multiple representation and the allotting of marks for each items, IFAA model proposed in this study is worth considering in educational validity and realistic adaptability.

The purpose of this study was to analyze the process of scientists' science knowledge generation by employing four creative scientists as participants. Raw protocols were collected by an intensive interview method and then analyzed by a psychological modelling procedure. The present study showed that the process of knowledge generation divided into the processes of inductive, abductive, and deductive thinking. Furthermore, the inductive process in simple and operative observation was involved in the processes of generating a question, conjecture/prediction, designing an operational method, operation, and simple observation. Also, the abductive process had two components; question generation, and hypothesis generation which consisted of analyzing questions, searching explicans, and constructing hypothesis. Finally, the deductive process involved inventing abstract test methods, inventing abstract criteria, inventing concrete test methods, inventing concrete criteria, collecting results, and evaluating hypotheses and stating conclusions.
