Generation and physico-chemical characteristics of municipal solid wastes are very important for sanitary management. However, that has not been investigated so far especially in chunchon. And so, we tried to examine many things in detail. It was resulted that density was $90{\sim}94kg/m^3$ in school and office zone and $290{\sim}298kg/m^3$ in apartment and market place. The compositional weight fraction was food, 40~54%, paper, 14~18%, vinyl and prastic, 14~20% in house zone and market place and paper, 42~70% in school and office zone. Moisture was estimated to be 54~57% in independent house zone, apartment and market place and 11~23% in school and office zone. And three composition was water content, 44.1%, incineration particle, 11.2%, volatile parts, 44.7% in respectively. That is because of seasonal effects and regional chracteristics. In the results of chemical composition and caloric value analysis, carbon(C) was 80% in vinyl and plastic and oxygen(O) was 54.4% in paper.

This study attempts to present a new interpretation of the Jeju province Waga, authorized as Jeju province Folklore, in the context of lifestyles of residents distinctive in the Jungji, Chatbang, and Gopang system. Study results uncovered that (1) only one Jungji, a traditional house kitchen, exists in one house boundary, in the form of detached building in the 4 units of Gaok (K-2 Gaok, K-3 Gaok, C-1 Gaok, and C-2 Gaok) (2) Chatbang had multifaced-functions; as a place for diet for mistress and children, a place for preparing meals for a mister who diet in the room, and as an auxiliary meal-preparation facility in time of domestic celebration day. (3) Gopang was mostly a place for grain storage, and K-3 Gaok has one unit, K-1 Gaok, C-1 Gaok, and C-2 Gaok had 2 units, and K-2 Gaok and H Gaok had 3 untis of Gopang. (4) Jungji and Chatbang were correlated for meal preparation and diet while activity-line of flow was divided each other. (5) Jungji and Gopang were located at the opposite edges of of each house, revealing no consideration of indoor activities. (6) The ratios of space of Jungji, Chatbang and Gopang out of the whole house space were, average 23% in the case of Jungji located in the inner house, and average 37% in the case of Jingji located in the detached building, average 14% larger in the case of detached Jungji system.

The multi-phase flow analysis in a solid rocket motor is very important when performing the performance of a motor, and prediction of nozzle ablation. However, only in consideration of regular power, it has analyzed as power which a metal particle receives from a flow until now. We conduct analysis and an experiment about the virtual mass clause which will influence at the place where acceleration is big. We aim at the improvement in accuracy of multi-phase flow analysis from the result.

A city is an ordinary space and a place of living that is directly related to our lives. An ordinary space is the total products of culture and the target of cultural representation. An aging residential area of a city reflects the ordinary lives of ordinary people along with its unique history; therefore, this place should not be seen only from an economic and political perspective. The Wausan area is a place that best maintains the characteristics and scenery of an aging urban residential area within Gwangju metropolitan city. Through research into this area, it is possible to discover the meaning and true value of an aging urban residential area such as the close relationship between ordinary culture and placeness, the creation factors and process of placeness of an aging urban residential area, and the authenticity of a particular place. This area is a modern residential area of today's ordinary people, created on a topography of hills and hilly areas along with a historical value of 400 years. It is based on the Gyeongyangyeok of the Joseon period. This place may be described as a space where the dailiness of ordinary people is alive based on its alleys and the unique scenery formed by its alleys and vegetable gardens. The authenticity deduced from such placeness is that an aging urban residential area is a place where communicative and considerate human life and a cultural diversity of an atypical nature are alive, a place where an environment and humans coexist in harmony, and a place where the communal dailiness of residents still exists.

This study intended to examine the differences through comparative analysis of the illustrations and contents in the 3rd-6th grade elementary science textbooks of Korea and Finland. The analysis of the types and illustrations in the Korean and Finnish textbooks revealed that the textbooks of both counties provide many photographs and illustrations, so as to deliver data mainly in the form of realistic illustration. In Korean textbooks, photographs were mainly used to guide the students into experiments and to train the students in analyzing and interpreting data. In contrast, the Finnish textbooks place more emphasis on pictures and photographs to enhance their interests and curiosity and understand. The Korean textbooks should place more emphasis on the pictures in order to encourage elementary school students to interest and understand. As a result the addition of more diverse forms of illustrations and the re-organization of illustrations according to the topic should be considered in future Korean textbooks.

Recently, the application of BIM has been continuously expanded according to various government policies, and the application performance is being analyzed in BIM projects such as roads and railways. In line with this trend, the government is making additional efforts to introduce full-scale design BIM. The BIM design in the public sector is directly related to the estimated price. However, looking at the current status of BIM introduction, there is no support system in place for calculating the estimated price. Therefore, this study intends to analyze the priority activity that is easy to develop BIM unit price among the construction standard unit Price of construction work. In this study, in order to derive the BIM-based priority activity, BIM application statements and application guidelines were analyzed. As a result of the analysis, cast-in-place concrete construction (civil engineering) and reinforced concrete construction (architecture) were deduced as suitable construction activities for the preferential application of BIM. Since the results presented in this study are a rough analysis, it is judged that additional detailed analysis is necessary for the future.

12 typical laminated composite reinforced concrete (RC) walls with different concrete ages and 3 cast-in-place RC walls subjected to low frequency cyclic load were carried out in this study. The failure mode, force-deformation response and energy dissipation capacity of these specimens were investigated. Differences of structural behaviours between composite RC walls and common cast-in-place RC walls were emphasized in the analysis. The compatibility of the composite specimens with different concrete ages was discussed based on the experiment. Test results indicated that the differences between the lateral bearing capacity and the displacement ductility of the composite walls and the common walls were not so obvious. Some of the composite specimen even has higher bearing capacity under the experiment loading situation. Besides, the two parts of the laminated composite specimens demonstrates incompatibility at the later loading sequence on failure mode and strain response when it is in tension. Finally, this laminated composite shear walls are suggested to be applied in rapid reconstruction structures which is not very high.

This study aims to introduce and assess CNN Deep Learning methods to analyze visual landscape images on social media with embedded user perceptions and experiences. This study analyzed visual landscape images by focusing on a healing place. For the study, seven adjectives related to healing were selected through text mining and consideration of previous studies. Subsequently, 50 evaluators were recruited to build a Deep Learning image. Evaluators were asked to collect three images most suitable for 'healing', 'healing landscape', and 'healing place' on portal sites. The collected images were refined and a data augmentation process was applied to build a CNN model. After that, 15,097 images of 'healing' and 'healing landscape' on portal sites were collected and classified to analyze the visual landscape of a healing place. As a result of the study, 'quiet' was the highest in the category except 'other' and 'indoor' with 2,093 (22%), followed by 'open', 'joyful', 'comfortable', 'clean', 'natural', and 'beautiful'. It was found through research that CNN Deep Learning is an analysis method that can derive results from visual landscape image analysis. It also suggested that it is one way to supplement the existing visual landscape analysis method, and suggests in-depth and diverse visual landscape analysis in the future by establishing a landscape image learning dataset.

Recently, many regional governments and national organizations have propelled public art projects as a part of city regeneration project for improvement of living environment and cultural welfare of neglected regions. It is necessary to think of meaning of the public art project in a context of city regeneration, not only in public art discourse. This paper starts from the question if recent public art projects performed in city of Busan during last 5 year was successful in terms of place marketing. This paper tried to revoke to consider public art project in terms of place marketing because it should be utilized ultimately to activate regional economy for the habitants. First, we reviewed theoretical background regarding definition of public art and place marketing, intended effects of public art project, and place marketing strategy. we elicited an analytical framework and analyzed representative 6 cases of recent public art projects performed in city of Busan in terms of requirements of public art project and viability of place marketing. Discussion of the analysis result suggested implications for the future public art project to direct.
