Considering the human visual masking property, a modified relationship between the activity function and the visibility threshold is developed. This leads to a novel objective appraisal method for blocking effects in a lossy subimage coding by virtue of the human visual sensitivity. The appraisal criterion is examined using a series of reconstructed images that are DCT-coded at various bit rates. Experimental results show that the presented blocking effect measure well agrees with the subjective ranking.

Superhero films have formed a new genre convention encompassing all the generations. Figures derived from image contents are solid figures produced by means of professional figuration skills. Possession of figures has a symbolic meaning as a medium connecting the imaginary world and real one. From this perspective, figures hold an important position as a character product derived due to market expansion of the content industry. In this context, the study, which analyzed how appraisal of outward visual elements in superhero action figures might affect consumer's purchase intention, aimed to identify their purchase patterns. For this, the study established colors, types of physical body, facial figures and motions as independent variables for appraisal of outward visual elements, and purchase intention as a dependent variable and then conducted a multiple regression analysis. As a result of the analysis, the study found that colors, types of physical body and facial figures had a positive influence on purchase intention, while motions had no significant influence.

Photography has been used as a typical tool of recording image since its invention in the nineteenth century. Photographs provide valuable visual information about all parts of society, and a systematic management must be preceded to use these information. The management and preservation system of photographs should reflect the characteristics of photographic medium. It is necessary for many archives to perform appraisal first to collect and manage enormous photographs. Appraisal is the process of determining meaning and value of records, and the reasonable criteria should be needed to carry it out. The purpose of this study is to suggest appraisal criteria for photographic records based on the archival appraisal theories and the characteristics of photography. This study draws on traditional appraisal theories and some literatures for archival management of photographs. This study is organized as follows. The first section examines the concept and values of photographic records and the distinctiveness of appraising photographs. The second section analyzes the existing appraisal criteria for individual records. The third section designs appraisal classes of photographic records and proposes the criteria for each classes.

Most of the agricultural structures are in shortage of feasible facility management because these structures are small in size and spacially distributed in rural area. Inspection tools based on visual inspections are generally used for agricultural structures in most of the countries, including Korea. It is necessary to survey data of the irrigation structures to maintain records, and to develop the interface program by constructing database of inspection data. This study was conducted to develop a system for safe appraisal and repair works on agricultural irrigation structures. Repair and rehabilitation method can be chosen from an optimum viewpoint if the information between the method and life-cycle management cost of agricultural structures is constructed in the database. In this study, the system assisting onsite field investigation and determining the typical rehabilitation method of typical agricultural structural problems such as fractures and cracks of members was developed.

Because of increasing numbers of cars many highways are being constructed lively, and the noise of passing cars has influenced surrounding areas. In consideration of this, some alternatives and researches for soundproof facilities are proceeding, but aesthetic approach hasn't been considered. Therefore, this research is focused on soundproof effects for each types, effectual simulation methods, visual assessment and estimation between the landscape before simulation and the landscape after. Soundproof facilities are divided largely by the soundproof barrier, the soundproof mounding, the soundproof grove. The soundproof grove has three main function. First, leaves and branches absorbs sound vibrations. Second, leaves absorbs sound, and branches obstruct sounds. Third, by means of sounds of shaking leaves, forest can offset noises. This research was proceeded by means of classification of soundproof grove types and investigation of visual simulation methods. We made visual simulation for each types, and estimated the landscape for each types.

Mobile (smartphone) search engine marketing is increasingly important. Accordingly, the development of visual apparel search technology to obtain easier and faster access to visual information in the apparel field is urgently needed. This study helps establish a proper classifying system for an apparel search after an analysis of search techniques for apparel search applications and existing domestic and overseas apparel sites. An annotation technique is developed in accordance with visual attributes and apparel categories based on collected data obtained by web crawling and apparel images collecting. The categorical composition of apparel is divided into wearing, image and style. The web evaluation site traces the correlations of the apparel category and apparel factors as dependent upon visual attributes. An appraisal team of 10 individuals evaluated 2860 pieces of merchandise images. Data analysis consisted of correlations between apparel, sleeve length and apparel category (based on an average analysis), and correlation between fastener and apparel category (based on an average analysis). The study results can be considered as an epoch-making mobile apparel search system that can contribute to enhancing consumer convenience since it enables an effective search of type, price, distributor, and apparel image by a mobile photographing of the wearing state.

In the Orient, most references are made on the visual perception of the eye having the blue iris, even in the case where the reference should be made on the perception by the eye having the dark iris. In order to clarify the difference in the visual perceptions of a monochromatic light, an objective boundary wavelength between hues incident on the dark eyes was obtained and the correlation between the valuesalready reported as having been obtained with the blue eyes was examined. A significant difference was found in the subjective boundary wavelengths of hues depending on the difference in the visual sensitivity distribution on the dark and blue eyes.

Discomfort glare is an important factor influencing appraisal for lighting environment. Unified Glare Rating (UGR) which has been proposed by CIE is one of the formula for evaluating discomfort glare. Position index is an important factor in the UGR formula. Position index was proposed by Guth in 1949. It has been used until present limiting upper visual field. Lower visual field has different sensation of brightness in comparing with upper visual field. Therefore, it is necessary to propose position index about lower visual field. The objective of this study is to investigate the brightness sensation in upper and lower visual field. First, the visual field was measured on the self-made Glare Tester. Second, luminance of the Borderline between Comfort and Discomfort (BCD) was measured on the glare Tester. Circular sources of brightness were located at various angular distances from the line of vision along five meridians, $0^{\circ}$, $45{\circ}$, $90{\circ}$, $-45{\circ}$, $-90{\circ}$. The size of the glare source is 0.0011sr. The luminance of the surrounding field, which extended over the entire visual field, was maintained $34ccd/m^2$. Ten subjects aged from 25 to 29 were participated in the experiment. The results show that the luminance of BCD on the line of vision is $4337cd/m^2$ and the glare sensation of the lower visual field is more sensitive than the upper visual field.
