This study developed teaching-learning materials for 10 class periods that applies design thinking process for the units of 'sustainable consumption' of home economic subject, and examined the learning experience of students in the class. After the classes, reflection journals and in-depth interviews from 276 male and female students in ten classes were analyzed. The main results are as follows: The five steps of the design thinking process of the Stanford University d-School were applied to develop teaching-learning materials for the 'Sustainable Consumption Practice Book Creation Project'. Students' positive learning experience was evidenced through sustainable consumption classes that applied design thinking. The students were able to reflect through the experience of sympathizing with the real problem, and experienced an improvement in problem-solving ability through the process of idea construction and prototyping. Students expressed difficulties in reaching consensus among the members, and in devising ideas and implementing prototypes. Based on the learning experience of students this study, it is suggested that home economic teachers further develop and implement classes of various topics to which design thinking process is applied. A future study may need to verify the effectiveness of home economic classes to which design thinking is applied.

본 연구를 통하여 대형할인점 이용자, 재래시장 이용자, 그리고 수퍼마켓 이용자들의 각 쇼핑장소를 중심으로 한 거주지역 공간적 분포 및 쇼핑패턴의 차이를 비교한 결과. 이 세종류의 쇼핑장소 이용자들간의 각 쇼핑장소들 중심으로 한 거주지역 분포의 공간적 패턴 및 쇼핑통행 패턴은 상당한 차이를 나타내고 있다. 또한 대형할인점을 이용자를 제외한 재래시장 이용자와 슈퍼마켓 이용자들을 대상으로 그들이 이용하기를 원하는 대형할인점의 이용을 제한하는 주요 요인을 분석한 결과 통행거리, 운전면허 미소지, 자가용 승용차 미보유 등 대형할인점으로의 접근을 위한 과정에서 발생하는 제약 요인들이 가장 큰 비중을 차지하고 있는 것으로 나타난다. 이러한 점들을 볼 때, 재래시장 및 수퍼마켓이 주민들의 일상적인 쇼핑장소의 역할을 할 때와는 달리 대형할인점의 등장은 이곳으로의 주민들의 접근능력의 차이에 따라 주민들간 일상적 소비장소의 차별화가 진행될 수 있음을 시사한다. 특히 최근 대형할인점의 입지가 가속화되고 이에 따라 재래시장 및 수퍼마켓의 기능이 쇠퇴하고 있음을 고려할 때, 신체적 그리고 사회경제적 특성의 차이에 따라 대형할인점으로의 접근에 제한을 받는 주민들의 일상적 소비공간은 더욱 위축되고 고립될 가능성이 있다.

In this paper, we evaluate the power consumption of IEEE802.15.4e TSCH which uses the specific link scheduling scheme proposed in reference[1]. And we also compares it with the power consumption of conventional single channel IEEE802.15.4. The power consumption of IEEE802.15.4e TSCH is smaller than the conventional one under the any conditions of traffic. The reasons can be explained as the followings. Firstly, TSCH does not have backoff time because of using the collision free link scheduling. Secondly, there is the timing difference of MAC offset parameter between TSCH and conventional IEEE802.15.4 Lastly, the devices in TSCH mode sleep during the time slots which are not assigned to itself.

오늘날 환경문제는 범지구적이며 인류의 생존 자체를 위협할 만큼 심각하다. 산업화가 환경문제 발생의 근원적 원인이다. 하지만 자연관, 자연에 대한 지식 증가, 기술개발, 경제성장과 불평등 등도 환경문제 발생의 중요한 원인들이다. 인구는 사회가 성립하는 데 필요한 요소이지만 환경문제 발생의 한 원인이 되기도 한다. 그 이유는 인구가 지탱되는 데 필요한 의식주는 전적으로 자연자원에 의존하고 있는데 인구의 크기는 자연이 감당할 수 있는 용량을 초과했기 때문이다. 이러한 관점은 인구와 환경의 관계에서 인구를 하나의 집합체로 보고 양적으로 접근한다. 그러나 환경문제 발생원으로서는 인구는 질적 차원에서도 접근할 필요가 있다. 즉 집합체로서의 인구를 구성하는 개별 행위자들이 일상생활에서 얼마나 친환경적 행동을 하는 가라는 점도 파악돼야 한다. 왜냐하면 절대 인구수가 같더라도 전체로서의 인구를 구성하는 개별 행위자들의 자연관, 생활양식 등에 따라 자연에 전개하는 행동이 다르고 결국 자연에 가해지는 영향(impact)이 다르기 때문이다. 집합체로서의 인구가 환경문제 발생원인으로 의히마는 바는, 자연자원의 공급량을 훨씬 초과해 추출한다는 점과 자연이 흡수 처리할 수 있는 능력 이상으로 생산${\cdot}$유통${\cdot}$소비과정에서 과도하게 폐기물을 발생시킨다는 점이다. 반면 개별 행위자로서의 인구가 환경문제 발생원인으로 의미하는 바는 풍요성과 편리성을 극대화시키고 일상생활에서 친환경적이지 않은 행동을 무분별하게 한다는 점이다. 이런 맥락에서 이 연구는 환경문제의 본질을 먼저 논의했고 환경문제 발생 메커니즘에 인구가 어떤 방식으로 적용하는 지를 두 가지 차원 - 집합체로서의 인구와 개별 행위자로서의 인구 - 에서 논의하였다.

Consumer capitalism is transforming real geographical knowledge into imaginary one through commodity fetishism. As a result, students' ability to think themselves and commodity relationally become weak. Thus, the students cannot recognize the positional meanings of themselves in the global networks of food and ethically perceive environmental issues that generate due to the interrelation between the students and the commodity networks. In these problematic consciousness and situations, this research examine relation of commodity consumption and ethics through hamburger connection and insists that geographical education helps the students acquire insight into the relationship between food and themselves through relational thinking.

Recent advances in sensor network technology have open up challenges for its effective routing. Routing protocol receives most of the attention because routing protocols might differ depending on the application and network architecture. In the rapidly changing environment and dynamic nature of network formation efficient routing and energy consumption are very crucial. Sensor networks differ from the traditional networks in terms of energy consumption. Thus, data-centric technologies should be used to perform routing to yield an energy-efficient dissemination. By exploiting the advantages of both ant colony optimization techniques in network routing and the ability of data centric muting to organize data for delivery, our approach will cover features for building an efficient autonomous sensor network.

At this point in time when the percentage of foreign consumers as well as domestic consumers are being increased in domestic open market users due to the recent interest and promotion on the open market, the purposes of this study are as follows. First, the relationship between open market brand personality, satisfaction and brand loyalty will be clarified targeting all Korean consumers and Chinese consumers using domestic open market. Second, whether there is difference in the effect of domestic open market brand personality on customer satisfaction and brand loyalty between Korean consumers and Chinese consumers will be compared. The results are as follows. First, as a result of testing the study hypothesis targeting the open market users, in other words targeting all Korean consumers and Chinese consumers, only the ability among brand personality dimensions did not have positive effect on the satisfaction toward open market. Other than that, it could be confirmed that the reliability, sincerity and familiarity, etc are important influence factors in forming satisfaction toward open market. Next, as a result of testing whether there is difference in the effect of domestic open market brand personality on customer satisfaction and brand loyalty between Korean consumers and Chinese consumers, it was shown as having difference. In other words, the Korean consumers were shown as not having positive significant effect in the relationship between the ability among brand personality and satisfaction toward open market while all other brand personality dimensions were shown as having positive effect on the satisfaction toward open market. It could be found that if the satisfaction toward open market is high, the brand loyalty toward open market also gets high.

Empathy is the ability to feel, understand, and respond to the emotions of others from the standpoint of others. Recently, 'sympathy' has emerged as an important issue not only in emotional empathy in relation to individuals but also in 'social empathy', which sees sympathy as a basic principle for maintaining society. This study focuses on the issue of empathy as a new driving force for modern society and focused on 'urban scene' as a spatial application for cultural empathy in the city. Urban scenes approach the city as a space of consumption, classify it according to its inherent attributes, and analyze its characteristics. This study approaches the existing urban scene theory in terms of empathy. In addition, as a way to consume city images reflected on contents, a concrete example of 'contents tourism'is examined, and a 'contents scene' is proposed as a new urban scene and its meaning and possibility are presented.

In the past, purchasing limited products was nothing more than purchasing expensive luxury goods. However, the current 'Limited product purchase' is not just pay to ability, but the information to purchase the product are important factors. Therefore, this study aims to find out 1) the motivation to purchase limited edition products and 2) the effect of the motivation on the consumer's experience(price, intention to purchase). As a result, five major purchase motives(Conformity, Interest, Scarcity, Finance technology, Desire to concede) were found. Among them 'Interest' had a positive effect on the product purchase price, and 'Conformity' had a negative effect on the product price. Next, 'Interest' and 'Scarcity' had a positively significant effect on intention to purchase. Through this study, we were able to reveal in depth the actual purchase motives of consumers who are currently emerging as the main age group of the new consumption culture, and expect these purchase motives to be actively used in the new market such as resell markets.

The objective of this study was to compare and analyze the acceptability and consumption attitude for soy foods between Korean and Canadian university students as young consumers. This survey was carried out by questionnaire and the subjects were n=516 in Korea and n=502 in Canada. Opinions for soy foods in terms of general knowledge were that soy foods are healthy (86.5% in Korean and 53.4% in Canadian) or neutral (11.6% in Korean and 42.8% in Canadian), dairy foods can be substituted by soy foods (51.9% in Korean and 41.8% in Canadian), and soy foods are not only for vegetarians and milk allergy Patients but also for ordinary People (94.2% in Korean and 87.6% in Canadian). In main sources of information about soy foods, the rate by commercials on TV, radio or magazine was the highest (58.0%) for Korean students and the rate by family or friend was the highest(35.7%) for Canadian students. In consumption attitude, all of Korean students have purchased soy foods but only 55.4% of Canadian students have purchased soy foods, and soymilk was remarkably recognized and consumed then soy beverage and margarine in order. 76.4% of Korean students and 65.1% of Canadian students think soy foods are general and popular and can purchase easily, otherwise, in terms of price, soy foods were expensively recognized as 'more expensive than dairy foods' was 59.1% (Korean) and 54.7% (Canadian), and 'similar to dairy foods' was 36.8% (Korean) and 39.9% (Canadian). Major reasons for the rare consumption were 'I am not interested in soy foods' in Korean students (27.3%) and 'I prefer dairy foods to soy foods' in Canadian students (51.7%). However, consumption of soy foods in both countries are very positive and it will be increased.
