개별화 학습은 단지 하나의 교수 학습 방법으로서의 의미가 아니라는 인식이 보편화되어 교실 수업뿐만 아니라, 성인 교육, 기업 교육 등 다양한 교수 학습 상황에서 관심을 끌어왔다. 한편 효과적인 개별화 학습은 학습자 특성에 대한 정확한 분석 및 측정이 필수적으로 요구되나, 학습자 특성에 대한 개념과 범주가 다양하고 광범위하여 그에 대한 계량적인 기술이 어렵다. 이에 본 연구에서는 학습자 특성을 인지구조와 인지양식으로 제한하였다. 또한 학습자 특성을 연결주의적 관점에서 기술하고 이를 기반으로 하여 학습자 특성의 정량화 기법을 제안하며 그에 대한 타당성을 검증하였다. 본 연구에서의 학습자 인지구조는 기존에 연구된 학습자 인지구조 객체를 간소화하였고 인지양식은 학습자 인지의 지식관성력으로 축소하여 기술하였다. It seems reasonable to assume that the individualized learning means more than simple teaching-learning method, so the instructional method has attracted a fair amount of attention not only in classroom, but also in the field of a adult education, cooperate education, and so on. In order to have an effect on individualized learning, we need to analyze and measure the learner's characteristic. However it is difficult to represent in quantified form because the conception and category of learner's characteristic is various and extensive. Therefore, in this paper, we propose a quantification method of learner's characteristic, which is limited to learner's cognitive structure and style, and is represented in the light of connectionism, verify the validity. The learner's cognitive structure in this paper was represented, which simplified the learner's cognitive structure. Additionally, the cognitive style in this paper was limited to inertia of knowledge for learner's cognition.

This study aimed to grasp trends of the discourse for improving living conditions carried out since 1920's, when the sense for mending the irrationality of conventional living emerged in various magazines. Among the movement, women intellectuals played an important roles to discuss reforming daily life and unhealthy, inconvenient houseworks. This study found the ideological background and direction of this discourse, and estimated its important role for housing improvement, analyzing the contents of articles published in representative womens' magazines of the modern times. In the discourse, they thought that it was most important to make houseworks brief and efficient, and concentrated on building rational environment for houseworks. As reforming kitchen system, heating system (Ondol) should be separated from cooking system to improve hygienic and economical condition of houseworks. Reformed kitchen would be equipped with new installations for effectiveness, lightened by sunlight through windows, and finished floor with cement and drainage for sanitation. Also, they suggested new ways of living, planning modern houses with reformed kitchen system, thinking about moving path and distance of housewives. This discourse would be a foundation to the change of kitchen system up to now.

This study examines the details and characteristics of prizewinning plans of Cho-Sun housing plan competition promoted by Daily Cho-Sun Company during Japanese colonial period. The main features of Cho-Sun housing plan competition were that the competition held with an application of popular newspaper readers and a judging committee was composed of only Korean architects, especially Park, Gil-Ryong as the president of the board of examiners. Cho-Sun housing plan competition put ideological factors for the improvement of living as like advancing to the cultured(modem) life, respecting for family life, respecting for privacy of family members and so on. First of all, the competition suggested the direction of the improvement of dwelling spaces which focused on making harmonious home life. This study found common characteristics of prizewinning plans of Cho-Sun housing plan competition as the result. First, Cho-Sun housing plan competition introduced a centralized house plan as a model of the improvement of small-sized houses. Second, architectural orders of western or Japanese style mingled with ones of korean traditional style in prizewinning plans as entrance hall, western style reception room(parlour), maid's room, bathroom for example. And a manner of seating using chairs was brought into the style of living which would be assumed in the prizewinning plans. Third, traditional way of composing dwelling spaces was maintained, receiving the characteristics of dwelling spaces of japanese style simultaneously, which central corridor was put at the heart of house for improving arrangement of rooms and flow lines. Fourth, lavatory and bathroom were placed inside of the house.

Line Shaped Solid Oxide Fuel Cell (SOFC) with multilayered structure has been fabricated via direct-writing process. The cell is electrolyte of Ni-YSZ cermet anode, YSZ electrolyte and LSM cathode. They were processed into pastes for the direct writing process. Syringe filled with each electrode and electrolyte paste was loaded into the computer-controlled robe-dispensing machine and the paste was dispensed through cylindrical nozzle of 0.21 mm in diameter under the air pressure of 0.1 tow onto a moving plate with 1.22 mm/s. First of all, the anode paste was dispensed on the PSZ porous substrate, and then the electrolyte paste was dispensed. The anode/electrolyte and the PSZ substrate were co-fired at $1350^{\circ}C$ in air atmosphere for 3 h. The cathode layer was similarly dispensed and sintered at $1200^{\circ}C$ for 1 h. All the electrode/electrolyte lines were visually aligned during the direct writing process. The effective reaction area of fabricated SOFC was $0.03 cm^2$, and the thickness of anode, electrolyte and cathode was 20 $\mu$m, 15 $\mu$m, and 10 $\mu$m, respectively. The single line-shaped SOFC fabricated by direct-writing process exhibited OCV of 0.95 V and maximum power density of $0.35W/cm^2$ at $810^{\circ}C$.

한국어 워드넷에서의 개념 유사도를 활용한 선택형 문항 생성 시스템

김용범,김유섭,Kim, Young-Bum,Kim, Yu-Seop 한국정보처리학회 2008 정보처리학회논문지 A Vol.15 No.2

본 논문에서는 난이도를 고려하여 선택형 문항을 자동으로 생성하는 방법을 고안하였으며, 학습자 수준에 적합하도록 동적인 형태로 다양한 문항 제시를 할 수 있는 시스템을 구현하였다. 선택형 문제를 통한 평가에서는 적절한 규모의 문제 은행이 필요하다. 이와 같은 요구를 만족시키기 위해서는 보다 쉽고 빠른 방식으로 다양하고 많은 문제 및 문항을 생성할 수 있는 시스템이 필요한데, 본 논문에서는 문제 및 문항의 생성을 위하여 워드넷이라는 언어 자원을 이용한 자동 생성 방법을 고안하였다. 자동 생성을 위해서는 주어진 문장에서 형태소 분석을 통해 키워드를 추출하고, 각 키워드마다 워드넷의 계층적 특성에 따라 유사한 의미를 가진 후보 단어를 제시한다. 의미 유사 후보 단어를 제시할 때, 기존의 한국어 워드넷의 스키마를 개념간 의미 유사도 행렬을 구할 수 있는 형태의 스키마로 변경한다. 단어의 의미 유사도는 동의어를 의미하는 수준 0에서 거의 유사도가 없다고 볼 수 있는 수준 9까지 다양하게 제시될 수 있으며, 생성될 문항에 어느 정도의 유사도를 가진 어휘를 포함시키느냐에 따라서 출제자의 의도에 따른 난이도의 조정이 가능하다. 후보 어휘들의 의미 유사도 측정을 위해서, 본 논문에서는 두 가지 방법을 사용하여 구현하였다. 첫째는 단순히 두 어휘의 워드넷 상에서의 거리만을 고려한 것이고 둘째는 두 어휘가 포함되어 있는 트리 구조의 크기까지 추가적으로 고려한 것이다. 이러한 방법을 통하여 실제 출제자가 기존에 출제된 문제를 토대로 더 다양한 내용과 난이도를 가진 문제 또는 문항을 더 쉽게 출제할 수 있는 시스템을 개발할 수 있었다. We implemented a system being able to suggest example sentences for multiple choice tests, considering the level of students. To build the system, we designed an automatic method for sentence generation, which made it possible to control the difficulty degree of questions. For the proper evaluation in the multiple choice tests, proper size of question pools is required. To satisfy this requirement, a system which can generate various and numerous questions and their example sentences in a fast way should be used. In this paper, we designed an automatic generation method using a linguistic resource called WordNet. For the automatic generation, firstly, we extracted keywords from the existing sentences with the morphological analysis and candidate terms with similar meaning to the keywords in Korean WordNet space are suggested. When suggesting candidate terms, we transformed the existing Korean WordNet scheme into a new scheme to construct the concept similarity matrix. The similarity degree between concepts can be ranged from 0, representing synonyms relationships, to 9, representing non-connected relationships. By using the degree, we can control the difficulty degree of newly generated questions. We used two methods for evaluating semantic similarity between two concepts. The first one is considering only the distance between two concepts and the second one additionally considers positions of two concepts in the Korean Wordnet space. With these methods, we can build a system which can help the instructors generate new questions and their example sentences with various contents and difficulty degree from existing sentences more easily.

Purpose: The question of surgical versus non-surgical treatment for diabetic foot osteomyelitis remains subject to debate. The aims of this study were to analyse the outcome of conservative treatment (antibiotic treatment and conservative surgery) for diabetic foot osteomyelitis and identify the predictive factors of remission in conservative treatment of diabetic foot osteomyelitis. Materials and Methods: Seventy-seven patients with diabetic foot osteomyelitis who initially received conservative treatment from January 2004 to July 2013 were identified, and their medical records were reviewed. Diabetic foot osteomyelitis was defined by imaging studies or histological evidence. Remission was defined as the absence of any sign of infection at the initial or contiguous site assessed at least 12 months after the end of treatment. The demographic, clinical, and therapeutic factors were analysed. Results: The mean age of the patients was $62.7{\pm}12.2$ years, and 47 patients (61.0%) were male. The median diabetes duration was $15.7{\pm}11.2$ years and mean HbA1c was $8.7%{\pm}2.4%$. Forty-eight patients (62.3%) healed with conservative treatment (antibiotic treatment and conservative surgery). Twenty-five patients (32.5%) underwent amputation. In the multivariate analysis, concomitant peripheral artery disease and inadequate antibiotic therapy were associated with failure of conservative treatment. Conclusion: Antibiotics alone, or with conservative surgery, were successful in treatment of diabetic foot osteomyelitis in 62.3% of the patients. Concomitant peripheral artery disease and inadequate antimicrobial therapy were risk factors for remission in conservatively treated diabetic foot osteomyelitis.

u-러닝(u-learning) 체제의 도입은, 원격교육을 지원하는 다양한 형태의 u-러닝 시스템 및 모형을 요구하며, 이에 따라 네트워크를 이용한 u-러닝 환경의 원격교육시스템에 대한 연구가 지속적으로 진행되어왔다. 하지만, 현재 운영되고 있는 대부분의 원격교육시스템은 교수자와 학습자간의 지속적인 쌍방향 상호작용 유지의 어려움, 시스템 구축을 위한 경제적 부담, 시스템 운영에 투입되는 교수자의 기술적 소양 부족 등 여러 문제점을 안고 있다. 이러한 문제점을 해결하기 위해서는, 교사의 접속 여부와 무관한 지속적인 학습 활동의 유지, 시스템 구축의 경제성 및 사용상의 편리성에 대한 고려가 선행되어야 한다. 이에 본 연구에서는, 이동성과 내재성 등의 u-러닝 개념을 포함하고, 가상 교수자(cyber tutor)의 결합에 의해 실제 교수자의 접속 상태와는 독립적으로 지속적인 교수-학습 과정을 지원하며, 사용자의 기술적, 경제적 부담의 제거가 가능한 지능형 u-러닝시스템을 개발하고, 그 적용 가능성을 검증하였다. A arrival of u-teaming paradigm requires many u-teaming system and model that is varied and support to distance education, Accordingly, the distance education system in u-learning environment has attracted a fair amount of critical attention. However there remain many questions, as yet unresolved, such as it is difficult to maintain interaction between tutor and learner, the construction of system is a great expense to them, a tutor, who manages the system, lacks technologic background, in most current distance education system. To solve these problem, some preliminary observations have to be made first: to keep teaming process in situation that it is unconnected with tutor, to construct the system economically, and to make to be easy-to-use. Therefore, in this paper, we develop the 'Intelligent U-Learning System using Cyber Tutor', which includes the conception of u-learning such as mobility, immanency, supports to keep learning without real tutor by cyber tutor, and removes technological and economical costs, verify the validity.
