Recently the development of China has attracted all over the world, many scholars of different areas are interested in Chinese Culture and Chinese Market. After sixties of last century development of the economic of the South Korea closer to modernization, but there are many problems, one of them is the urban living style boasts of the features of concentration. Because of this phenomenon the lack of housing space become more serious. It also come to be a social problems. Therefore narrow residential area become inevitability. At the same time, effective utilization of housing space become a demand. Especially for those families with limited living space, it's meaningful for them. Between the China and the South Korea. Chinese have the same situation too, the different is kitchen space of chinese is closed. It means they have to cook in limited space. With increased supplies and more small appliances, an inevitable requirement is opening out the kitchen space, but unreasonable furnishings and living space reduces the efficiency of the kitchen, which has led to the discontent of users. From this, base on the investigation and analysis of diet&living space of most chinese apartment, and through differences kinds and places of storage items. With them I would combine the food culture and feature of storage space of China to solve problems of the efficiency of the kitchen.

Various policies and studies regarding use of PBSS (Public Bike Sharing System) and Programs (PBSP) have been conducted worldwide as the number systems or programs has increased. Although various phenomena and demands have been generated by the use of PBSS in everyday life, the majority of research and the policies in South Korea have been implemented focused on commuting life. The purpose of this study aimed to understand various PBSS demands using PBSS usage data in 2018 in the Yeouido districts through classifying usage patterns and analyzing features. The rental stations were classified into three types based on weekday/weekend usage rates. The usage of Yeouido's PBSS accounted for 4.3% of the total usage in Seoul Metropolitan City, while the number of PBSS rental stations accounted for 2% of all rental stations in the Seoul urban areas. Rental stations with a higher weekday utilization rates showed high utilization rates in all four seasons and were mainly distributed in work and residential areas. Other stations showed a concentrated usage pattern in spring (April-May) and autumn (September-October) seasons, and their locations were close to the entrance of nearby parks. Besides, renting and returning were often concentrated at certain rental stations for high weekend utilization as compared to the pattern of high weekday usage. Therefore, PBSS management and programs should be operated to reflect various usage demands rather than uniform PBSS operations. The result of this study is meaningful to provide basic data for effective PBSS operation by monitoring the demand for PBSS usage in spatio-temporal terms.

This study used three types of temporary shelters, tents, and prefabricated houses provided by the Chinese government for victims after the Wenchuan earthquake in 2008 as case study objects. Through literature review, 12 evaluation items were selected from the social, economic, and environmental elements of the sustainability of residential space design to analyze and evaluate three types of temporary shelters, and derive their respective characteristics and problems. The analysis results show that the temporary centralized settlements and tents had problems such as imperfect infrastructure, poor sanitation, narrow living space, no personal space, and inconvenience in life. Prefabricated houses had problems such as high construction costs, non-environmentally friendly building materials, occupation of arable land, low recycling rate of materials, and environmental pollution by waste. The common problem of the three types of shelters was that the government took the lead in the construction and distribution of shelters, and the disaster victims passively accept government support. Therefore, disaster victims were not actively involved in the construction and management of temporary communities. Secondly, the designs of all three types of temporary shelters did not fully consider the psychological needs of the victims, especially the need for safe and hygienic personal space. Finally, this research proposes improvement plans for the problems in the sustainable design of three temporary shelters and the construction and management of temporary communities.

This study analyzed the observation characteristics with the subject of observation data through defining the change of the observation degree as attention /conscious observation /visual understanding. Furthermore, by obtaining the formular with which to estimate the subjects' observation amount, this study suggests a potential method for easier analysis of observation characteristics. The conclusions from the study are as the followings. First, the observation frequency was being generated with wide deviation among subjects while there was a flow-on characteristics depending on the degree of observation. These characteristics enabled the study to obtain the formular with which to estimate the observation amount. Second, the study could establish the area frequency by grade from the entire observation data. The area I was at most 4% for the area frequency but accounted for 18.2% of the entire effective observation time, and the area II 16% and 38.7% respectively. Accordingly, only considering the observation area distribution of the area I or the areas I and II shows which position of the space the subjects were observing. Third, with the subject of the relatively higher observation time at at the subject's observation characteristics, as the observation phase was getting higher, the observation time decreased more. Forth, by obtaining the formular to estimate the observation amount for observation data according to the change of observation degree, the study could find the estimating observation characteristics of additional subjects. The formular shortens the analysis time and facilitates the analysis process.

최근 건설기술의 발전과 함께 강재 케이블을 이용하는 시설물의 시공이 점점 증가하는 추세이다. 특히 현수교, 사장교와 같은 초장대 교량에 사용되는 케이블은 주거더 및 상판에 의한 하중의 대부분을 지지하는 핵심부재이다. 하지만 이러한 케이블 부재는 부식, 파단 등으로 인한 단면손실이 발생할 수 있고, 이로 인한 손상부의 응력집중으로 인해 시설물 전체의 붕괴로 이어질 수 있는 위험성을 가진다. 따라서 조기에 단면손실을 찾아 사고를 미연에 방지할 수 있는 강재 케이블 비파괴 검사 기술기반의 건전성 모니터링이 필수적이다. 이러한 효율적인 건전성 모니터링을 위해 스마트 센서를 활용한 연구가 활발히 이루어지고 있는데, 그중 대표적인 스마트 센서중 하나인 마그네틱 센서는 높은 신뢰도와 어디에나 적용 가능한 재현성 때문에 구조물 건전성 평가에 적용하기 유용한 기술로 그 적용범위가 선박, 항공등으로 점점 넓어지고 있는 추세이다. 마그네틱 센서는 그 적용대상에 따라 다양한 마그네틱 특성을 활용할 수 있는데, 최근에는 투자율 계측을 통해 케이블의 장력 측정이 가능한 Elasto-Magnetic 센서(E/M 센서)가 개발되었고 그 활용성에 대한 연구가 이뤄지고 있다. 이에 본 연구에서는 E/M 센서를 이용한 강재 케이블 모니터링 기술을 제안하고자 한다. E/M 센서는 본래 케이블의 장력측정을 위해 개발되었지만 본 연구에서는 강재 케이블 부재의 단면손실 검색을 위해 적용하였다. 제안된 기술의 실험적 검증을 위해 E/M 센서를 이용하여 4가지의 다른 직경을 가지는 강봉시편을 E/M 센서헤드의 1차 코일을 통해 자화시키고, 각각의 직경에서 출력전압을 2차 코일을 이용하여 계측하였다. 그 결과 강봉의 직경이 감소함에 따라 출력 전압이 감소함을 보였다. 반복실험을 통해 해상도 및 선형성이 확보되는 최적의 입력전압과 출력전압의 워킹포인트를 선정하였고, 선정된 조건에서 강봉시편을 일정 간격으로 스캔한 결과 단면감소에 따른 선형적인 출력전압 감소와 동시에 단면 변화 지점에서는 추세선에서 크게 벗어난 출력전압 계측값을 나타내었다. 본 실험을 통해 제안된 E/M 센서를 이용한 강재 케이블 모니터링 기술의 유용성 및 적용가능성을 확인할 수 있었다.

With the introduction of smart phones, the augmented reality became popular and is increasingly drawing attention. The augmented reality in the mobile devices is becoming an individual area to study. Many applications of the augmented reality have been studied, but there are just a few studies on its combination with artificial intelligence in games. In this study, an artificial intelligence algorithm was proposed, which dynamically converts the state of the 3D agent in the augmented reality environment using the 3-Axis acceleration sensor in the smart phone. To control the state of the agent to which the artificial intelligence is applied, users used to directly enter the data or use markers to detect them. The critical values, which were determined via test, were given to the acceleration sensor to ensure accurate state conversion. In this paper, makerless tracking technology was used to implement the augmented reality, and the state of the agent was dynamically converted using the 3-Axis acceleration seonsor.
