The National Museum of Korea has striven for the stable preservation environment for its collection as it reopened in October 2005. The temperature and humidity, harmful gases in the collection storage space and the galleries were regularly measured to confirm whether the environment was stable for the collection; the material that could directly influence the collection such as showcases were tested in advance to select stable material. In addition, to prevent biological damage, whole collection was fumigated; insect monitoring traps have been regularly established to check the status of the collection storage space.

We propose a new method that specifies objective image quality factors by evaluating an image quality measurement model using random images. In other words, No-Reference variables are used to evaluate the quality of an original image without using any reference for comparison. 1000 portrait images were collected from a web gallery with votes constituting over 30 recommendation values. The bottom-up data collecting process was used to calculate the following image quality factors: total range, average, standard deviation, normalized distribution, z-score, preference percentage. A final grade is awarded out of 100 points, and this method ranks and grades the final estimated image quality preference in terms of total image quality factors. The results of the proposed image quality evaluation model consist of the specific dynamic range, skin tone R, G, B, L, A, B, and RSC contrast. We can present the total for the expected preference points as the average of the objective image qualities. Our proposed image quality evaluation model can measure the preferences for an actual image using a statistical analysis. The results indicate that this is a practical image quality measurement model that can extract a subject's preferred image quality.

앱 인벤터는 GUI 환경에서 블록 편집기를 사용하여 앱을 개발한다. 따라서 누구나 쉽게 앱 프로그래밍을 시작할 수 있다는 장점이 있다. 또한, 앱 인벤터의 공식 사이트의 gallery 공간에 공개된 수많은 공개 앱 소스(aia 파일)를 쉽게 구할 수 있기 때문에 다른 사람이 만든 앱의 소스를 그대로 가져다가 이미지만 바꿔서 자신이 만든 것처럼 앱을 공개할 수도 있다. 그러나 직접 블록 단위로 비교해보지 않고서는 표절이나 도용 여부를 판단하는 것은 쉽지 않다. 따라서 본 논문에서는 앱 인벤터로 개발한 앱들의 유사도를 자동으로 계산해주는 도구를 개발하였다. 원본 프로그램과 도용된 프로그램은 유사도가 높게 계산될 것임을 예상할 수 있기 때문에 유사도 계산 프로그램은 코드 도용을 확인하는 목적으로 활용될 수 있다. 본 논문에서 구현한 도구의 평가를 위해서 다양한 실험을 수행하였고, 실제로 유사도가 높았던 앱들이 서로 공통된 블록을 다수 포함하고 있음을 밝혀내었다. 이러한 실험결과를 바탕으로 우리가 개발한 도구가 앱 인벤터로 개발한 앱에 대해서 소스 표절이나 코드 도용을 탐지하는 목적으로 활용될 수 있을 것으로 기대한다.

The form and function of modern museum present more a variety of aspects in need of transition of the mature civil society and culture than the past. Considering that an art museum is the space where a multitude of unspecified visitors inspect simultaneously, exhibitions and adequate construction make visitors lead to successively visual contact. Consequently a goal of this study is to analyze that there is correlation between exhibit space and exhibitions and to suggest an alternative plan at exhibition through relationship among exhibitions, exhibit space and spectators' behavior. Two Art galleries (one is a large-sized gallery and the other is a small-sized one) located in Pyung-Chang dong were selected to analyze the correlation and suggest the better display for the exhibition. The finding of the study is following. The exhibit space which spectators recognize is assumed diverse forms by an unique characteristics of exhibits and space and an arrangement of exhibitions and the path of flow of spectator who walking ahead have an huge effect on a spectators' behavior. In other words, spectators' watching patterns are affected by display of exhibitions and the path of flow. That is to say, the spectators' behavior and the concentration to watch exhibitions is decided by the exhibit form in the museum, and the quality of watching experience is depended on the spectators' relevant knowledge prior to exhibitions.

This paper provides suggestions for analyzing Cultural Objects Name Authority(CONA) developed by the Getty Trust and applying CONA to Functional Requirements for Subject Authority Data(FRSAD). CONA is linked with the other Getty controlled vocabularies such as AAT, ULAN, and TGN, and can be linked with the library controlled vocabularies, such as LCSH. However, CONA has differences with library models since CONA is based on the art museum or art gallery. Therefore, we need to consider it when we link CONA to library standard models. The results discussed in this study have implications for analyzing CONA which provides access for cultural objects and applying it to the FRSAD, the subject authority model in library fields.

Deformation of caisson occurred during the backfilling behind the caisson and some caisson moved toward seaside. A series of site investigation were conducted to figure out various circumstances at site and also used to analyze the cause of deformation. The soil condition of backfilling is also investigated because dredged material was used as a backfill material. The friction angle of backfill is supposed to be lower than the estimated one which was used in design stage. To determine the cause of friction shortage, back analysis for sliding safety were carried out with considering the soil condition of backfilling. A remedial plan, re-rising and relocating a caisson with backfilling good earth after treatment of caisson rubble mound to achieve the safety for sliding was proposed as a best solution based on the back analysis results. Reform concrete structure including service gallery and crane rail was also considered with the remedial work to improve the cape line of caisson.

Healthcare design is always challenged to come up with the rapid changes in healthcare system and industry as well as complicated planning requirements. This thesis aims to grab good instructions from Louis I Kahn who designed more than 15 healthcare projects during his entire life, from the winning project of the student competition in 1920 to Ayub hospital in Dhaka, Bangladesh after his death. His many hospital projects are deeply related to his famous projects such as Yale Art gallery, Philips Exeter Library, and Sher-E-Bangla Nagar national capital of assembly hall. But, it is not easy to find the researches about his hospital projects among many books and theses about him. Thus, this thesis investigates them and their contextual and historical relationships in order to find the way to apply his knowledge and philosophy about healthcare design to the modern hospital projects. We expect that it will promote more following researches for his healthcare projects.

The purpose of this study was to serve as a basis for the creation of new design. For attaining the purpose, an investigation was made into the actual condition or problems of domestic and foreign fashion design, and fashion design information was acquired from the Internet. Then, taking the acquired information as the basic data for merchandising, an attempt was made to work out an outline by using the Corel-Trace program, a widely-used computer software, and to modify it by using the Corel-Draw program. The findings of this study were as below: 1) The informations provided by domestic home-pages were largely made up of fashion news and articles on the trend of fashion, but included few of picture report. Almost all of them weren't developed into a database by item or detail. The foreign fashion design web-site were numerous in number, providing diverse information. They offered not only moving images or picture report on fashion show, leading models, photo gallery or fashion trend, but up-dated data everyday. 2) A way to create a design to meet a designer's target is recommended in this study. At first, the fashion information acquired through computer network would be handled by the Corel-Trace program. After Bitmap image would be converted into Vector image, that would be modified by the Corel-Draw program to create a design to suit a designer's target.

This paper presents the device of recognizing image of the studded paving blocks, transmitting, the information by vibration to a visually handicapped person. Usually the blind uses the walking stick to recognize the studded paving block. This research uses a PCA (Principal Component Analysis) based image processing approach for recognizing the paving blocks. We classify the studded paving blocks into 5 classes, that is, vertical line block, right-declined line block, left-declined line block, dotted block and flat block. The 8 images for each of 5 classes are captured for each block by 112*120 pixels, then the eigenvectors are obtained in magnitude order of eigenvectors by using principal component analysis. The principal components for images can be calculated using projection of transformation matrix composed of eigenvectors. The classification has been executed using Euclidean's distance, so the block having minimum distance with a image is chosen as matched one. The result of classification is transmitted to the blind by electric vibration signals with different magnitudes and frequencies.

Dicyanate-clay nanocomposite has been prepared by a melt in-situ polymerization method for different modifiers and cation exchange capacity (CEC) values in order to study dispersion and mechanical property. Various dicyanate nanocomposites were prepared by using different MMT systems containing different intercalants which led to different initial gallery heights and packing density. Depending on compatibility between dicyanate and clays, the degree of dispersion varied. Dispersion of clay plates in dicyanate resin depended mainly on CEC and aliphatic chain length of modifier. The lower CEC and shorter aliphatic chain length of modifier gave the exfoliation structure. It was also found that the reactivity of intercalant with dicyanate resin was one of the key factors facilitating the intercalation/exfoliation process of dicyanate/MMT nanocomposites. Shear modulus of reaction-induced dicyanate nanocomposite was significantly increased.
