In the midst of growing demand for rural life of urban dwellers, this study tried to investigate the difference in behavior and recognition about urban rural exchange between Korea and Japan. For this, this study utilized 2,000 total samples of the survey conducted by MLIT in Japan, because Japan has experienced a low birth rate and aging population earlier and actively promoting urban rural exchange program than South Korea. The result of the analysis is as follows. First, the needs for rural life of urban dwellers are similar both in Japan and South Korea. However, Japanese prioritize future efforts to current efforts. Second, urban dwellers' activities in rural areas were classified into three categories; field trips and hands-on activities, cruise and circulating activities, and leisure activities. Third, similarly three types of visit or intercourse of urban dwellers into rural areas were classified; repeatedly visit the same place as 'iterative type', visit a new place as 'new pioneer type', and not yet determined as 'undefined type'. Variables such as age of household, income, number of inmate, and number of children were analyzed linked to these three types of visit or intercourse in a Discriminant analysis. As a result, only 'age of household', however, turned out to be the crucial factor which influence decisively distinguishing characteristics of these three types of visit into rural areas.

The purpose of this study is to examine cinematic representations of places in the Korean War films on the event of 1950 'Incheon Landing', focusing on the place representations. 'Incheon Landing' of September 1950 provided a turning point for the Korean War, and the event can be interpreted totally different from the South Korean and the North Korean perspectives. Two films on the same event of the 'Incheon Landing' - a South Korean film, "Incheon Landing Operation"(1965), and a North Korea film, "Wolmido"(1982)- were selected as major sources of analysis and comparison. each director has different intentions. One film was taken from the landing army's viewpoint, whereas the other film was taken from the defender's viewpoint. As a result, one film emphasized the battle as a spectacle of glorious victory from the landing army's viewpoint, while the other film glorified those soldiers killed in the battle as heroes from the defender's viewpoint.

In this paper, the real state of using terms 'product', 'place value', 'nine-nine', and 'numeral' incorrectly or inconsistently in the area in Korean elementary school 1-2 grade math textbooks/workbooks are analyzed. Based on this analysis, the following four conclusions are presented. First, 'Product' should be defined in the ${\ll}$Math 3${\gg}$ textbook like 'sum' and 'difference'. Multiplication is introduced in the ${\ll}$Math 3${\gg}$ textbook/workbook, however, the result of that calculation is not referred to 'product'. Second, there is a need to reconsider the using the term 'place value' in 2nd elementary mathematics. In the ${\ll}$Math 3${\gg}$ and the ${\ll}$Math 4${\gg}$ textbooks/workbooks are not using the term 'place value' clearly. Third, the word 'addition nine-nine table' and 'subtraction nine-nine table' should not be used in the ${\ll}$Math 2${\gg}$ and the ${\ll}$Math 4${\gg}$ textbooks. Using the term 'multiplication nine-nine' and 'multiplication nine-nine table' in elementary school mathematics textbooks/workbooks instead of using the term 'nine-nine' and 'nine-nine table' respectively would be the possible cause of these inaccurate derivatives. Fourth, in 1st and 2nd elementary mathematics 'numeral' and 'number' should be used discriminately. There is a need to reconsider the using the term 'number' uniformly if possible.

Technology for electric lighting has been evolving from Incandescent Lamp(IL) through Fluorescent Lamp(FL) and currently to Solid State Lighting(SSL) such as LED for more than 130 years of time. However, it took more than 100 years until the transition from IL to FL across overall society. That is because the transition is the Socio-Technical Transition(STT) which involves various social elements. This study investigated and analyzed the theories regarding STT, and applied the Multi-Level Perspective(MLP) theory to the case of electric lighting. A qualitative contents analysis was used with secondary data as research method, and the analyzed result was visualized based on the frame of MLP theory. The STT of electric lighting from IL to FL took place as the order of Technical Niche, Socio-Technical Regime and Landscape. Specifically, in Technical Niche level: Establishing Market Niche, Price-Performance Improvement, Learning Process and Support of Powerful Group took place. In Socio-Technical Regime level: Changes in Social Network, Changes in Technology and Changes in Rules. In Landscape level: Macro-Political Development, Socio-Economic Trends and Macro-Economic Trends took place in consecutive order.

Ground-source (Geothermal) heat pump (GSHP) systems can achieve a higher coefficient of performance than conventional air-source heat pump (ASHP) systems. However, GSHP systems are not widespread in Japan because of their expensive boring costs. The authors have developed a GSHP system that employs the cast-in-place concrete pile foundations of a building as heat exchangers in order to reduce the initial boring cost. In this system, eight U-tubes are arranged around the surface of a cast-in-place concrete pile foundation. The heat exchange capability of this system, subterranean temperature changes and heat pump performance were investigated in a foil-scale experiment. As a result, the average values for heat rejection were 186${\sim}$201 W/m (for pile, 25 W/m per Pair of tubes) while cooling. The average COP of this system was 4.6 while cooling; rendering this system more effective in energy saving terms than the typical ASHP systems. The initial cost of construction per unit for heat extraction and rejection is ${\yen}$72/W for this system, whereas it is f300/W for existing standard borehole systems.

Namhansanseong fortress (南漢山城) is not Eupchi (邑治) created for ages but the new settlement of public and military administration as Baedo (陪都) to defend capital territory. Namhansanseong has Jinsan (鎭山) that is named Cheongnyangsan (淸凉山) and its government office building was located in the main place, also a periodic five-day market was being held in the center of fortress. This study is find out the transition and its historical background of government office building on Namhansanseong by the relocation of Eupchi in the 17th century. The conclusion of analysis can be summarized as follows; The main change of government office in the late Choson dynasty is to move Yi-a, administrative complex (貳衙) around Yeonmugwan (演武館). Since 1795, the 19th year of King Jeongjo (正祖), this was fixed by the end of the Choson dynasty on the unification of Magistrate which is also Defense Commander. In the second place, the military office on Jungyeong (中營) that is Junggun's (中軍) place of work was abolished by the reform of Junggun system. Thirdly, transition of the end of the Choson dynasty is the abolition of Sueoyeong (守禦營) and the realignment of government offices. Namely, the administrative agency was moved to Haenggung (行宮) after the collapse of unification in 1895. Also former military offices was changed to police administration on Gwangju-bu (廣州府), Gwangju county level unit.

The trend of abstract expressions has become one of the fundamental causes of the problems relating to a sense of place in modern architecture. This trend began in earnest after the era of modernism, caused by the effect of modern dualism. Before analyzing the problems of the modern trend of abstract expressions and sense of place, a fundamental review of the establishment of human environments is necessary. In this context, this study deals with the principles of the establishment of an environment based on the logic of projection between human beings and milieu, through the concept of mediance by Augustin Berque, and based on this, causes of adverse effects on the establishment of environments in modernism were verified. In addition, the last section covers the conceptual supplements required in order for the concept of mediance to become practical, overcoming its limitation of being simply theoretical. Through this analysis on the concept of mediance, it is realized that a genuine sense of place can be achieved only when architecture moves beyond the individual dimension as a simply physical object, and instead plays a role as a socially sustainable community, embracing the people and unique objects therein.

This study attempts to provide implications for developing more efficient and effective community-based support system with AIP perspective for the elderly in Korea. The main purpose of this study is to analyze Japan's community-based integrated care system that respond to the concept of aging in place (AIP) and its cases. In Japan, they have offered Community-Based Service since 2005, and the advanced system which include integrated support categories and consolidated community/local resources will started in 2015 by The revision of Long-term Care Insurance policy, 2012. The result of policy analysis and case studies are as follows: 1) The suggestion for ideal support system model promoted a relationship of multiple agents include private sectors even resident and senior and specified responsibility sharing, 2) the system proposed Not only health and medical care support, living care and residence are also addressed as a comprehensive support. and 3) the amount of available community resource is different by each local government, but the effort to get the understanding of community residents and to connect with a potential community resource is also essential aspect to set effective community-based support system.

If see CISG's passing of risk and altered regulations first, when sales contract accompanies transport of goods and seller does not have duty to deliver goods at particular place, when deliver to the first carter to send to purchaser according to sales contract risk passes to purchaser, and when there is duty that seller must deliver goods to carter at specification place, when goods are delivered to carter at same place, risk does not pass to purchaser. Second, risk about transporting goods passes to purchaser at signing a contract. But, when there is special assessment, risk passes to purchaser when goods are delivered to carter who publish document that embody contract of carriage. Nevertheless, it is loss if seller did not notify this truth to occasion purchaser who could knew loss or damage of goods or know justly at sales contract conclusion defamation danger seller of be burdensome. Third, seller has responsibility about damage or loss as long as hide in own artificiality or forbearance after risk passes to purchaser. Regulation about risk in Incoterms 2010 was separated into 11 condition, and move time of risk differs in angle condition. It is appeared that the substance handles relatively comprehensively because compare in Incoterms 2010 although it is because it becomes if it examines regulation about deliver and passing of risk of goods setting in CISG relatively concise. Also, segments that can become posibility of analysis controversy exist.

The use of hybrid FRP-concrete structures with a dual purpose of both permanent formwork and reinforcement, has been considered in some studies recently. For the FRP plank and the concrete to act as a composite structural member a satisfactory bond at the interface between the smooth surface of the pultruded plank and the cast-in-place concrete must be developed. Sand was bonded to the pultruded FRP plank using a commercially available epoxy system. In applying general analysis techniques to evaluate the performance of composite structures with FRP stay-in-place forming, it is essential that characteristics of the bond stress-slip relation be identified. In this study I would like to propose a simplified bilinear bond stress-slip model for FRP composite structures.
