The purpose of this study is to inquire original design and character of dancheong in Yeongnamnu Pavilion which features unusual portraits of twisting dragons and four heavenly creatures. Its artistic value and originality can be found in the portraits of four heavenly creatures which are painted on the interior seonjayeon(fan shape rafter) and in the unique design of crossbeam meoricho(flower decorations on each side of pillars). Yeongnamnu’s crossbeam meoricho is janggu-meoricho type(meoricho with hourglass figure) with full-shape lotus and half-shape flower decorations. And it can be said that, dragon portrait painted on the border of lotus and flower decorations in green and yellow is a very unique style of dancheong, for the reason that it has scarcely been used before and ever since. The portrait of four heavenly creatures painted on each corner of seonjayeon is also found to be unique in design, for the reason that the design has rarely been used throughout history, with only two exceptions in mural tombs of Goguryeo and folding screen in Injeongjeon Hall of Changdeokgung Palace . With its unique and authentic feature along with its rarity in number, the portrait of four heavenly creatures painted on Yeongnamnu can be considered as quite symbolic and important.

Recently, application content which is applied by gamification elements has been enhanced. However, gamification elements has not been strongly applied in the life-logging application. Because, this application is not focused on fun, but on the visualization of the data and the records of the user's external or internal information. Therefore, the purpose of this paper is to establish the gamification elements for 'life-logging' service. To do this, the gamification elements were extracted and classified by surveys, exploratory factor analysis and confirmatory factor analysis. As a result, the gamification elements for life-logging applications are formed by three factors; ‘Acting’, ‘Achievement’, and ‘Social’. As the established gamification elements are effectively applied to life-logging applications, it is expected to be a basis for helping to provide enjoyable behavior and usability beyond the common function of user record.

There were lots of changes of the wooden structure in the middle of Joseon Dynasty. It was the time of replacement from Jusimpo (simple bracket system) to Ikgong (wing-like bracket system) and each bracket had shown mutual variation as well as itself. The aspects of change were discovered that the decorative elements of Ikgong and Dapo (multi-bracket system) had accepted from each other. It was clearly shown that not only the Ungung (carved cloud-shape) and Chotgaji (shape of the acuminate leaf) of Ikgong had affected to Dapo, but also Gaang (pseudo-pointing cantilever) of Dapo had affected to Ikgong. It was mostly found in the Buddhist architecture because there was the conservatization of ruling hierarchy as well as the active growth of Buddhist society.

The mobile device users have been increasing significantly because of the development of social network system. Mobile educational serious games are occupying a large portion of the serious game market but there is a lack of the quality evaluation elements for providing useful quality evaluation information about educational serious game to user or developer. This study conducted prioritizing the quality elements of mobile educational serious game contents. Then, these elements are decomposed into sub-elements and resulted into a hierarchical model with three levels. To evaluate the priorities among elements, AHP(Analytic Hierarchy Process) is adopted. Additionally, if the evaluation element of this study would be applied into other game contents, it can provide the fundamental information for quality improvement of total mobile educational serious game contents.

This study aims to survey current chicken industry and the status of technology based on the KAFACI project on the promotion of good management for increased productivity of market oriented small scale chicken producers in Nigeria. The agricultural sector has been identified as a virile sector with varieties of opportunities for the much sought diversification of revenue base and employment generation in Nigeria despite the dominance of smallholder farmers. The chicken enterprise has being a component of the livestock industry showing increasing importance. Growing entrepreneurships for sustainable growth of the industry requires investigating the prevailing environment in market-oriented chicken production in Southwest Nigeria. This study investigated the production practices, constraints of market oriented smallholder chicken farmers. Data were generated through farm survey of 240 farmers selected by multi-stage sampling techniques from 5 out of 6 states in the Southwest. Data were analyzed using descriptive statistics. The study shows a population of famers dominated by male 76.7% and average year of education of 13.88years. Foundation stock of birds are prominently sourced from commercial hatcheries (75.8%) and reared under intensive management system (87.8%). Majority of the farmers (46.7%) are into rearing of layers, broilers and cockerels with an average stock size of 449, 157 and 158 birds respectively. Birds are fed twice daily (74.8%) on compounded ration by 95.4% of the farmers. Major production constraints are high feed cost (32.1%), shortage of capital (30.0%) and poor access to market (25.4%). However, 96.7% of the farmers considered the enterprise profitable.

In this study, refined finite element (FE) analyses intended to evaluate the capacity of the existing water purification plant structures against seismic force are conducted with an aim to predict possibility generating tension crack and compression crushing. The FE models for three types of main plant structures were constructed to take ground condition, boundary condition, and water interaction into consideration for advanced simulation. The nonlinear dynamic analyses were performed by using ground motion data which have been used for seismic design. Both compression crushing and tention crack, which are distributed over concrete plant structures during peak ground acceleration (PGA), are investigated by analyzing failure possibility controlled with the strain limits. After observing FE analysis results, it is possible to predict tenstion cracking which can be found at some parts of the main structure.

This study mainly evaluate the aseismic performance of the existing intake tower structure, which is one of the national important infra structures, on the basis of the refined finite element (FE) analysis results. The realistic evaluation for structural damage was conducted by using the nonlinear material model that takes tension and compression strength of deteriorate concrete into consideration during FE modeling. In addition, not only tension crack but also compression crushing was analyzed by utilizing field contour functions provided in the program during nonlinear dynamic analyses when peak ground acceleration (PGA) occurred. After observing FE analysis results, it can be shown that the damage of the intake tower is the most likely to occur at the water level and the base support.

PURPOSES : Road subsidence occurs owing to road cavities, which cause many social and environmental problems, especially in cities. Recently, road cavities were detected by various ground radars and repair works were carried out against the detected cavities. The condition assessments related to the road cavities are necessary to understand the potential risk of the cavities. Therefore, in this study, a numerical study was performed to assess the various conditions of road cavities. METHODS : The numerical method adopted in this study is the discrete element approach, and it is suitable for analyzing the condition because it can consider the movement of the soil particles in the surrounded cavity areas. In addition, the triaxial test was modeled and performed under various cavity conditions inside the specimens. RESULTS: The conditions of different cavity locations and shapes were analyzed to identify the effect of cavity state. Three general cases of particle size distributions were formulated to identify the effect of surrounding ground conditions. As a result, the degree of decrement and volumetric strain were varied depending on the locations and shapes of the cavity. Only minor changes were observed when the particle size distributions were altered. CONCLUSIONS: The strength reduction was higher when the cavity formed was larger and located in the upper zone. Similar to the cavity shape, strength reduction and volume deformation are more influenced by the width than the length of the cavities. There is an influence from ground conditions such as the particle size distribution, especially on the wide cavity.

Communication using SNS(Social Network Service) with others has become the trend through quantified-self - users’ explicit and implicit data are measured, recorded and automatically stored- as life-logging application industry has been grown. As the life-logging application is focused on recording and sharing the data, regular and simple interactive functions are used rather than dynamic and tense features. The game elements are used popularly in the mobile applications. Also, funware factors have begun to be applied in life-logging application. This paper intends to analyze for 20 life-logging applications with sorting collection, point, feedback, exchanges, customization in funware factors. The result of this analysis is that ‘Point’ factor is far better than others, and ‘Exchanges’ and ‘Customization’ factor common in the funware. Specially, the data report in the ‘Point’ factor shows the result visually by analyzing the data based on characteristics of life-logging application. However, if Exchanges and Customization factor are used in application development and design, the value of life-logging concept is more increased. Therefore, attempts which is not a simple function as users’records but enjoyable actions are expected in design of life-logging application that is consistently rising.

The purposes of this study were to investigate the emotional consumption propensity and the preferences for sensibility factors of fabrics(color tone, pattern and texture image), and to analyse the differences according to demographic variables and relationships between emotional consumption propensity and preferences for sensibility factors of fabrics, focusing on male and female consumers in 20's, 30's and 40's. The emotional consumption propensity were classified into symbolic consumption propensity, individual consumption propensity, aesthetic consumption propensity and hedonic consumption propensity. The subjects attached great importance in the order of aesthetic consumption propensity, individual consumption propensity and symbolic consumption propensity. Those factors of emotional consumption propensity showed partially significant difference according to demographic variables. Female consumers preferred various color tones than men did, and preference for light color tone showed significant differences according to gender and occupation of consumers. The preferences for floral pattern showed significant difference according to gender, age, education, occupation and marital status of consumers. The factors of the texture images for the fabrics showed partially significant difference according to demographic variables except education of consumers. There were almost significant relationships between emotional consumption propensity and the preferences for sensibility factors for fabrics.
