Currently, Korea is achieving cultural, economic, and social growth as a member of the international community along with its social growth. In the 2000s, local communities and local governments made multidimensional efforts with historical and cultural interests. And as part of that, historical museums were built or expanded to increase the quantity in anticipation of citizens' satisfaction and attracting visitors. However, the qualitative effect of the exhibition space is not achieved. Therefore, in this study, the analysis according to the complex system theory on the interrelationship between exhibition planning, space, and spectators was carried out based on the case of domestic historical museums, and future exhibition space planning or movement lines according to the mutual relationship between the exhibition space and the spectators were conducted. The purpose of this study is to conduct research on specific visualization and data derivation regarding spatial density and spatial perception information.

Typography's original meaning was printing by a plate or a printing type. Nowadays, Typography covers graphic design that composes types visually. Typography has an important mean because of two functions-linguistic and image building functions. Typography helps conveying information and making images. As new media appears, audio-visual factors take an important role. Therefore Typography's image building function be more important than linguistic function. This thesis will handle the relationship between typography and game contents. How typography is described through game contents and how typography's meaning are explained in game contents are topics. And typography's functions and factors on On-line game will be discussed.

New product development requires information on customers' emotions such as vision, auditory, olfactory, gustatory, or tactile perceptions. In this study, tactile sense which has not been well studied compared to other senses, was measured and statistically analysed for different surface roughnesses of plastic samples. The emotional responses of 37 pairs of positive and negative adjectives describing tactile senses were collected and analysed through the questionnaire to find the correlation between adjectives and surface roughness. Frequency of the first preference for each adjective on four different roughness is obtained, and used for the statistical studies such as factor analysis, multidimensional scaling, or clustering.

A new image coding technique has been proposed based on the wavelet transform. To achieve lower ceding rates and good qualities in reconstructed images, some of wavelet coefficients were removed by thresholding and quantized in accordance with the sensitivity of the human visual system(HVS). For each block of subimages in wavelet transform domain, block thresholding scheme has been used to remove the unimportant wavelet coefficients according to the frequency characteristic and statistical property of wavelet coefficients. The location information of quantized blocks and removed blocks were encoded using run-length coder which is effective for the exponential distribution. Quantized coefficients were encoded using variable length coder which matches well to their distribution. Simulation results show that the reconstructed images maintain high quality with the low bit rate, below 1.0 bits per pel.

과거의 수질관리는 오염물질의 수질농도에 중심을 맞춰서 이루어져왔다. 하지만 최근 국내에 수질오염총량관리제도가 도입되고 시행되면서 농도 중심의 규제보다 과학적인 접근 방법으로 균형적인 국가개발과 함께 수질보전을 이루는 성과를 나타내고 있다. 따라서 우리나라 물관리 종합대책은 수질관리대책에서 통합유역관리체제로 전환되고 있으며, 새로운 물환경 정책추진 기반 구축과 하천환경변화에 따른 유역 관리방안이 필요한 실정이다. 따라서 본 연구에서는 각각의 유역특성이 명확한 시범 유역으로 황강, 남강, 금호강 유역을 선정하였으며, 수질측정망 자료와 기상관측소 자료를 활용한 요인분석을 통해 수질-기상 항목 간의 공분산과 상관관계 등을 이용하여 변수들 간의 상호관계를 분석하였다. 요인분석 결과를 토대로 문항과 변수들 간의 상관성 및 구조를 파악하여 여러 변수들이 지닌 정보를 적은 수의 요인으로 묶어서 유역별 수질 변동특성을 파악하였다. 요인 분석결과를 토대로 시범유역별 유역특성을 평가하고 상세진단을 통해 향 후 유역별 관리체계의 방향성을 제시하고자 하였다.

This study suggests the need for polar literacy education as an effective conceptual system to explain climate change in terms of science education in line with the common effort of humankind to respond to global environmental changes. To this end, we investigated the status of polar literacy in high school students through quantitative tests and qualitative interviews and discussed the resulting implications. A total of 329 high school sophomore students from two high schools participated in a test consisting of 25 true and false questions developed by referring to the Polar Literacy Principles, while 13 students agreed to be interviewed. The results showed that a somewhat insufficient understanding and conceptual gaps appeared regarding several areas of the Polar Literacy Principles. Knowledge of the geographic features of the polar regions was weak, and little was known about the components and key characteristics of the cryosphere. The lack of understanding of these concepts results in the inability of students to link the operational mechanisms of polar and global climate change sufficiently. While accepting unsatisfactory concepts in the school curriculum without criticism from outside media, students perceived the mechanism of climate change as somewhat monotonous or distorted. Moreover, linguistic information, analogies, and visual observation were used as cognitive strategies to compensate for the ambiguous understanding of polar and climate change. Based on the abovementioned results, we argue that polar literacy education should be introduced as a new knowledge system that can be used to aid a systematic and comprehensive understanding of climate change within the school science curriculum. Additionally, we suggest the following implications: review the consistency of knowledge related to polar literacy in other subjects, provide critical standards for out-of-school media information related to climate change, examine students' misconceptions, and identify improved thinking strategies.

One of the main functions of the 4D system includes visualizing numerical schedule data in construction. The existing 4D tools have an excellent function for simulating building projects that all activities are progressed according to vertical work zone. However, it is not easy to implement all of it in the civil engineering project because the construction activities of highway and railway projects are progressed on the horizontal work zone and the 4D simulation for those projects should include earthwork objects that depend on the natural ground condition. This study suggests a new methodology for improving those limitations of 4D system for the civil engineering project and develops a new system by the suggested methodology. To verify the developed system, this study attempts to simulate 4D object for horizontal elements such as earthwork, paving work and tunneling work. The morphing and multi-texturing techniques developed in the study can be new approaches to simulate 4D object for the earthwork such as cutting and banking whose activities are progressed on the natural ground condition. The research results can be expected as a draft function for improving the application of 4D system in civil engineering projects.
