Now, our urban space is composed of all kinds of sculptures that lost its individual charm in trend flows and street furniture standardized by the integrated design of standardized franchises and similar architectures per each region and autonomous districts. This study was to introduce the concept called the 'community furniture' in the urban environment that there is no an identity of the regional culture and a sense of place because of the mostly similar street environment. The purpose of this study is to propose the concept called the 'community furniture' referred to as public facilities that imply specific identities of some regions that have became the community art expanded into necessary facilities of urban composition as bus shelter's universal convenience and functionality have been preferentially handled and its regional identities are reflected. For doing this, this study fulfilled application alternatives of community furniture design's basic principles after examining the storytelling process of local cultural heritages and analyzing domestic and foreign cases of bus shelters. Results of this study are as follows. First, convergent synergy effects in information and culture and art sectors could be expected as bus shelters visually deliver storytelling factors that imply locally related images. Second, space and place's characteristics and sustainable design concepts embody local characteristics. They can suggest directions for vitalizing urban environment designs by being in harmony with surrounding environments. Third, it is expected that realizing distinctive places is possible as bus shelters with local communities' aesthetic consciousness and regionality are composed of new street spaces.

The gate of university can be the first impression of the University itself and most important advertising structure which is more than just a structure that people pass by. It can also be the medium that connects the outside with the inside of the campus. Therefore, many universities are willing to have a unique and symbolic gate of their own. Recently, university representatives have become interested in arranging external areas of the campus. At this respect, studying and researching university gates and surroundings facilities must be realized. We visited 104 different universities gates to research and survey people about what they think of the internal and external individuality of each gate. According to these researches we established a full data base of 24 types of classifications, 5 characteristic forms of each shapes, 8 forms of the symbolic characteristics of university gates and 10 surroundings facilities of the university gates.

The research purpose of this study, together with the study of Frank Stella's work and his expansion of the formative arts field, is to rediscover "Amabel" and to present a fresh perspective in evaluating and assessing environmental art objects. The results of this study can be summarized as follows. 1. The study investigated the effect how Frank Stella's work affected American modem art trends. 2. The study helped to re-evaluate Stella's work by examining its expansion into the plastic arts. 3. The study analysed the plastic works of Prank Stella and his effect on plastic arts within the modem art trend of America. In conclusion, Frank Stella played a leading role in today's American art style and had a potent influence on the trends of America's modem U. In recent years, his work has had an impacted on the design of parks and art galleries. America's industrial society is led by the growth of economic power and the development of science and technology. In America's architecture and landscape architecture, such new forms as minimalism functionalism, cubism and abstract expressionism, which have been influenced by art movements, emerged in California and the east coast. Influences of Stella such as these are the remedy for a vested stubborn concept of architecture and landscape architecture by introducing a sense of pictorial space in these fields. In landscape architecture, the introduction of art trends appears in several ways. Mainly the trend of Minimalist Art, influenced by Modernism, can be seen in much Landscape Architecture. Frank Stella contributed to the development of such minimalist art.

BACKGROUND: Dithiocarbamte fungicides have been used in crop cultivation for diseases protection and treatment. And cultivated agricultrual products were used as feedstuff, and residual pesticides are likely to be absorbed and transferred to livestock. But the maximum residue limits (MRLs) were not established for dithiocarbate fungicides in livestock products, and thus an analysis method was developed and validated for dithiocarbamate fungicides to establish MRLs. METHODS AND RESULTS: Samples were prepared using CS₂ trap method and detected with UV/VIS spectrophotometer. Calibration line (0.1 ~ 10 ㎍/mL) was linear with r² > 0.99. For validation, the recovery tests were carried out at three fortification levels (MLOQ, 10 MLOQ and 50 MLOQ) from livestock samples (egg, milk, beef, pork, and chicken). The results for mancozeb, propineb, and thiram ranged between 76.8 to 109.6%, 79.4 to 108.8%, and 80.2 to 107.8%, respectively and % RSD (relative standard deviation) values were below 9.5%. Furthermore, inter-laboratory analysis was performed to validate the method. CONCLUSION: All values were corresponded with the criteria ranges requested by both the CODEX (CAC/GL 40-1993, 2003) and MFDS guidelines (2016). This might be used as an official analytical method for determination of dithiocarbamate fungicides at established MRLs and monitoring.

3D printing technology of construction field can be divided into structural materials, interior and exterior finishing materials, and is mainly done by extruding and adapting. Particularly when it is applied as an exterior materials, it is mainly applied to an unstructured exterior materials and high accuracy is required. The exterior materials can be used as a cement composite materials, it is suitable also for a additive type manufacturing, and the role of a redispersible polymer powder is important. But, high temperatures, redispersible polymer cement base material beget dehydration and micro crack of cement matrix. In this research, we developed a EVA, EVCL redispersible polymer cement base material applicable as a 3D printing exterior materials, confirmed density and strength characteristics for application as an exterior materials, a flame retardancy test for improving the fire resistance of buildings and confirmed its possibility. From the test result, developed EVCL redispersible polymer cement mortar showed good stability in high temperatures. These high temperature stability is caused by the ethylene-vinyl chloride binding. Thus, this result indicates that it is possible to fire resistant 3D printing interior and exterior finishing materials.

Imidacloprid is a neonicotinoid insecticide widely used for insect control in a variety of crops. The evaluation of imidacloprid total residues in animal feeds derived from crop by-products is required to ensure the safety of livestock products. We performed simultaneous LC/MS/MS analyses of imidacloprid and its metabolites in five different livestock products including beef, pork, chicken, milk and egg from domestic markets. The methods for sample preparation and instrumental analysis were established by modifying QuEChERS method to meet the Codex guidelines. The methods generated 0.0035 mg/kg of the limit of determination (LOD), 0.01 mg/kg of the limit of quantitation (LOQ) and standard calibration linearity with >0.983 of the coefficients of determination (R²). The methods exhibited the recovery values of imidacloprid and its metabolites ranging from 65.66 to 119.27% without any interference between matrices. Imidacloprid total residues in the livestock products were found as values lower than the LOQ and maximum residue limits (MRLs). This study suggests that the methods are successfully applicable for the safety evaluation of imidacloprid total residues in livestock products from domestic markets.

As major public owner agencies in Korea have improved the application level of BIM, many design and construction companies are paying more attention to ways to improve actual work productivity in the BIM execution process. In this study, we introduce a method to automate the placement of BIM libraries, a recurring task in the BIM-based design process that serves as a prime example of BIM design automation methodologies. In particular, we classify the target surfaces for placement of BIM libraries into straight lines, curves, vertical planes, and surfaces. For each target surface, we implement a BIM library automatic placement model in Dynamo, considering the spacing and alignment according to the distance between the centers of two objects and the linear length. The results of case studies confirm that the proposed method can be employed according to various placement environments and conditions with the working time shortened. The study proposes that various objects and structures that need to be placed according to the terrain characteristics can be placed accurately, and work productivity can be significantly improved through the automation of placement.

Large sized buildings have proliferated in the modern world in order to solve problems caused by the growth of cities, and this trend has lead to diversity in style and utilization of interiors. In particular, wayfinding within the shopping mall for a customer is a common problem, so if customers do not have to face these navigational problems and could find the way more easily, then shopping mall or the store can expect much better profits. Therefore, directional sign system that can provide accurate and speedy information for customers with diversified ages, gender and knowledge is necessary. Firstly, the definition and element of all directional sign are analyzed through the existing literature survey. The elements are based on the practical elements and six categories such as type, pictogram, color, layout, form, and location were considered. Secondly, directional signs in large underground shopping mall was considered, and the speciality of the underground shopping mall was investigated, and finally top three underground shopping malls was analyzed. Thirdly, through the questionnaire, an objective appraisal of directional signs and problems was developed, and following possible improvement was suggested. This study has its own limitations since it is only applicable to the specific locations, however, directional designs will be useful in other types of buildings as well. Through the continuous studies of the users' psychology, these kinds of studies will be related to the environmental characteristics of various places.

It is important to inherit and develop the unique cultural characteristics of each country and region in the trend of globalization. The traditional lighting fixtures in China are the main artifacts that can be used to extract the cultural aesthetics and practicality of the people, and are a major relic of the people's cultural sensitivities and practicalities. The purpose of this study is to understand the background of the time and the meaning of national culture through the lighting equipment of the most revived Tang Dynasty in Chinese history. The purpose of this paper is to examine the development trend of lighting equipment in the Tang Dynasty through the recognition of the social background, religious thought, cultural characteristics, and characteristics of lighting fixtures in the Tang Dynasty. In this paper, we analyzed seven factors (function, molding, fuel, usage space, usage method, religious thought, and living environment) of the Tang dynasty lighting fixtures through multiple factor analysis method. In addition, the Tang Dynasty period lighting fixtures had four trends: "popularization of lighting, universal simplification of molding, diversification of use, and spread of Buddhist influence." This tendency has a meaning to provide a new motive for modern lighting design in the context of cultural uniqueness and perspectives.
