The purpose of this study was to survey the citizens for their satisfaction with the outdoor landscape lighting in Gyeongju Historic Areas registered as UNESCO World Cultural Heritage in November 2000 and thereupon, provide for some basic data useful to the design of the outdoor landscape lighting for the cultural properties. As a result of examining the conditions of the outdoor landscape lighting in Wolseong Zone of Anapji, Banwolseong, Dongbu Sajeokji, Cheomseongdae and Gyerim, there were found 391 lighting fixtures of 12 types in Anapji, 138 lightings of 4 types in Banwolseong, 38 lightings of 6 types in Cheomseongdae, 28 lightings of 3 types in Dongbu Sajeokji and 54 lightings of 5 types in Gyerim. As a result of analyzing citizens' satisfaction with the outdoor landscape lighting, it was found that citizens were satisfied more or less with the nightscape image changed by the outdoor landscape lighting; their satisfaction scored 3.836 on average for Anapji on a 5-point Likert type scale, 3.516 for Banwolseong, 3.446 for Dongbu Sajeokji, 3.650 for Cheomseongdae and 3.479 for Gyerim. However, citizens' satisfaction with the originality of the nightscape was generally low: 3.055 for Anapji, 2.914 for Cheomseongdae, 2.877 for Banwolseong, 2.847 for Gyerim and 2.665 for Dongbu Sajeokji. On the other hand, since most of the lighting fixtures were installed as inserted lights or floodlights, the color tones of light source were relatively highly distinctive, but the peripheral spaces around the cultural properties were rather dark, which means that citizens were feeling inconvenient more or less for using the amenities such as bench or waste box. All in all, their satisfaction with the outdoor landscape at the sample zone at night scored 2.981, lower than the normal level.

This study investigated the influential range of landmarks and the relationship between landmarks and cognition factor so as to offer basic data to be used for the effective use and the management of landmarks. In this study, eighteen famous landmark in Seoul were selected and analyzed. The result of this study can be summarized as follows : 1) First, eighteen determining elements of cognition factors were selected via documents survey. Second, general cognition factors of landmarks were analysed using these elements through questionnaires to specialists. As a result of factor analysis, historic cultural factor, scale factor, visual form factor, locational factor and uniqueness factor were revealed. 2) According to revealed cognition factor, eighteen landmarks are categorized into four types using MDS method via questionnaire to resident in Seoul city. These four types of landmarks are: type I that are recognized by historic cultural factor; type II that are recognized by scale factor; type III that are recognized by uniqueness factor; and type IV that are recognized by visual form factor. 3) As the result of regression, the influential range of landmarks were revealed at about a 10km radius(type I : 12km type II : whole area of Seoul city≒15km, typeIII : 8.7km, typeIV : 8.5km). 4) As a result of analysing the correlation between the influential range and the cognition factor through multiple linear regression analysis, the locational factor is the main factor affecting the influential range of landmarks in every type. The uniqueness factor comes next, which affects influential range partially. 5) Except type 1, as a result of analysing the correlation between influential range and the physical heights of landmarks, a quadratic equation is revealed, showing that the influential range of landmarks over 200 meters in height shows a radical change. Landmarks can be used as reinforcement tools of legibility, effective tools for landscape management and for the improvement of a community's image. This study on the influential range of landmarks and main cognition factor can be utilized as a landmark management plan and in urban planning, such as a new town plan.

수학의 여러 분야 가운데 패러독스가 가장 풍부한 분야는 확률 통계 영역이다. 이것은 역사적으로 확률 통계 이론의 전개 과정에서 지난 시기 동안 연구자들이 직관과 상식에 의해 참이라고 믿고 있었지만 그 사이에는 감춰져 있던 다양한 패러독스들이 존재했으며, 이 패러독스들을 수학자들이 밝히고 수학적으로 해결해 나가면서 현재의 형식적 체계에 이르게 되었음을 시사하는 것이다. 학교 수학에서 확률 통계 영역의 교수 학습 자료로 적절하게 활용할 수 있는 역사적 패러독스들은 그 당시 현실적 맥락의 도입에 따른 학생의 흥미와 관심을 불러일으킬 수 있으며, 또한 교실 수업에서 역사 발생적 원리에 따라 패러독스를 제기하고 해결하고자 고민한 수학자들의 수학적 사고를 엿볼 수 있는 타당한 교수 학습 자료이다. 더불어 확률 통계 영역에서 역사적 패러독스를 활용하는 교실 수업은 형식적이고 연역적인 학교 수학을 학생의 발견적 형성적인 측면을 강조하는 수학으로 변화하게 할 수 있다. 이에 본 연구에서는 확률 통계 영역의 형식화 과정에서 발생한 역사적인 패러독스들 중에서 중 고등학교 확률 통계 수업에 활용할 수 있는 패러독스들에 대해서 알아보고, 또한 이 패러독스들을 교실 수업에 활용할 수 있는 구체적인 방안에 대해서 논해보고자 한다.

Kyeongbokgung succeeded in regaining its status as a royal palace after the reconstruction that began in the second year of King Gojong(1865) only to have most of its buildings taken down in the early 20th century. Fortunately, however, there is the Pukkwoldohyong(Map of North Palace), which drew out each of the buildings of Kyeongbokgung and their arrangement in details in 1907 when the royal palace lost its original appearance. And there is another plot plan of the royal palace at the Korea University Museum, which labeled it Kyeongbokgung-Baechido(Planning Map of Kyeongbokgung Palace). The map presents almost the same plan as Pukkwoldohyong in terms of making and expressive methods, being estimated to have been made in 1888 since its building arrangement doesn't show the changes made after 1890. The map also offers more information about the uses of each building than Pukkwoldohyong and matches the excavation results of the relics. Kyeongbokgung-Jeondo(Map of Kyeongbokgung Palace), which is recorded to be made during the reconstruction of the palace in the early years of King Gojong in historical materials, describes the shapes and arrangements of the buildings in a concrete and realistic fashion. The Kyeongbokgung-Baechido seems to be one of the plans made in the process of restoring and repairing buildings that were lost or destroyed in fire. The Kyeongbokgung-Baschido has the following historic values; 1) it provides dues to estimate the early state of the palace after the reconstruction during the reign of King Gojong. In fact the Sujeongjeon and Heungbokjeon show the early state of the reconstruction; 2) it contains data with which to understand the changes to the palace after 1890, around which they added Hamhwadang and Jibokjae; and 3) it offers information about the uses of the palace's buildings from 1885 to 1880 with its descriptions of the building purposes and relationships regarding the life in the palace.

In this study, we applied the long short-term memory (LSTM) model to classify the cryptocurrency price time series. We collected historic cryptocurrency price time series data and preprocessed them in order to make them clean for use as train and target data. After such preprocessing, the price time series data were systematically encoded into the three-dimensional price tensor representing the past price changes of cryptocurrencies. We also presented our LSTM model structure as well as how to use such price tensor as input data of the LSTM model. In particular, a grid search-based k-fold cross-validation technique was applied to find the most suitable LSTM model parameters. Lastly, through the comparison of the f1-score values, our study showed that the LSTM model outperforms the gradient boosting model, a general machine learning model known to have relatively good prediction performance, for the time series classification of the cryptocurrency price trend. With the LSTM model, we got a performance improvement of about 7% compared to using the GB model.

Due to recent growing interest in autonomous software agents and their potential application in areas such as electronic commerce, the autonomous negotiation become more important. Evidence from both theoretical analysis and observations of human interactions suggests that if decision makers have prior information on opponents and furthermore learn the behaviors of other agents from interaction, the overall payoff would increase. We propose a new methodology for a strategy finding process using data mining in autonomous negotiation system ; ANSIA (Autonomous Negotiation System using Intelligent Agent). ANSIA is a strategy based negotiation system. The framework of ANSIA is composed of following component layers : 1) search agent layer, 2) data mining agent layer and 3) negotiation agent layer. In the data mining agent layer, that plays a key role as a system engine, extracts strategy from the historic negotiation is extracted by competitive learning in neural network. In negotiation agent layer, we propose the autonomous negotiation process model that enables to estimate the strategy of opponent and achieve interactive settlement of negotiation. ANISIA is motivated by providing a computational framework for negotiation and by defining a strategy finding model with an autonomous negotiation process.
