With the spread of Smart phone, utilization of the Smart phone in the Internet shopping increases more than PC. In this paper, we analyzed whether impulse buying and overconfidence in the Internet shopping activity by consumers would be different between Smart phone and PC channels. We implemented the test of hypothesis with t-test by analyzing the survey data collected from users experienced the Internet shopping with Smart phone or PC. As a result, we discovered that there were differences of impulse buying and overconfidence in the Internet shopping activities between Smart and PC. The Smart phone was higher than PC , analyzing in views of average values for impulse buying and overconfidence in survey data. We discovered that consumers with Smart phone in Internet shopping activities could be make purchase of goods more impulsively than PC. We also found that online shopper with Smart phone could tend to overestimate their own purchase decisions than PC. This means that marketers need to establish the differentiated strategies in marketing for only channel based on Smart phone.

双位相空間이 J.C. Kelly에 依하여 導入된 以來이 空間에 關한 여러 가지 性質들이 硏究되고 있다. 本論文에서는 그 중 双分離性에 關하여, 双正規空間보다 條件이 弱한 双 m-正規空間을 正義하고 이 空間에 關하여 다음 性質을 밝혔다. 双位相空間()가 双 m-正規空間이면, 任意의 正規閉集合 A와 A를 품는 正規閉集合 B에 對 해서, 다음 條件을 만족하는 開集合 V가 存在한다. ; The concept of mildly normal spaces has been introduced by M. K. Singal and Asha Rani Singal in [2]. A topological space X is said to be mildly normal if every pair of disjoit regularly closed sets F1 and F2 of X, there exist disjoit open sets U and V such that F1U and F2V. A bitopological space (X, ) is pairwise normal [1] if for every -closed set A and -closed set B such that AB=, there exist a -open set U and -open set V such that AU, BV and UV=; In this paper we introduce the concept of pairwise mildly normality which is weaker than pairwise normality. Throughout the paper -clA denotes the closure of A for the topology .

The purpose of this study is to improve the aesthetic environment of the idle facilities left untreated through rehabilitation based on the comprehensive analysis process of existing domestic idle facilities and tourist hotels, We want to help the regional revitalization. Currently, there is no architectural form of redevelopment and demolition in the whole country, and the waste building that is abandoned or neglected is increased, and the space of the facility etc. does not meet the demand that is demanded in modern society, The number of idle facilities that are generated due to management failures such as pushing or running the facility is increasing. We aim at revitalizing neighboring area such as sightseeing spot by exploiting such idle facilities and regenerating and planning for accommodation hotel.

논문 및 특허 분석을 통한 3D프린팅 산업 시장 동향 예측 연구
장상목,한성웅,손규현 한국지식재산교육연구학회 2022 지식재산 교육과 연구 Vol.10 No.2
3D프린팅 기술은 4차 산업혁명의 대표적인 제조 기술로 혁신의 핵심이 될 것이라는 예측이 많았다. 3D프린팅은 기존의 금형·사출·주조 방식에 비해 제조 효율성을 높일 수 있을 뿐만 아니라 새로운 제조 경험까지 가능하게 하는 차세대 기술로 주목받고 있으며, 최근 발생한 코로나19 감염병 상황에도 불구하고 산업용 3D프린팅에 대한 수요가 확산되고 있다. 한편, 3D프린팅 시장이 기대보다 활성화되지 못하고 있다는 우려와 향후 시장이 위축될 수 있다는 전망도 있다. 본 연구에서는 국내 3D프린팅과 관련된 현재까지의 연구·지식재산권의 추이와 산업 동향을 기반으로 향후 기대되는 3D프린팅 산업 시장 동향에 대해 연구하였다. 국내 3D프린팅 산업의 동향 예측을 위해 논문-특허-시장 규모 현황을 조사한 결과, 2014년 이후 2019년까지 세 항목 모두 유사한 형태의 지속적인 성장세를 보였으며, 논문 출간은 특허 등록에 선행하여 증가추세를 보였음을 확인하였다. 시장규모는 논문-특허의 증가에 종속되어 증가하지 않고 특허 등록의 증가 추세 이전에 선행적인 증가 추세를 보였다. 3D printing technology is a representative manufacturing technology of the 4th industrial revolution, and there were many predictions that it would become the core of innovation. 3D printing is attracting attention as a next generation technology that not only improves manufacturing efficiency compared to the existing mold, injection, and casting methods, but also enables new manufacturing experiences, and the demand for industrial 3D printing is spreading despite the recent outbreak of COVID-19. On the other hand, there are concerns that the 3D printing market is not as active as expected, and there is a prospect that the market may shrink in the future. In this study, expected market trends in the 3D printing industry have been investigated based on the research and intellectual property rights related to domestic 3D printing. By examining the previous studies on the relationship between paper-patent-market size, from 2014 to 2019, all three items showed a similar type of continuous growth, and it was confirmed that the publication of papers showed an increasing trend prior to patent registration. The market size did not increase depending on the increase in paper-patents, but showed a leading increase trend before the increase in patent registration.

It is the most important subject matter to develop mathematical teaching materials in order to improve the quality of math education and to modernize math education in the middle school, however, we have found that there are few research concerning this matter. In this paper, we first analized the math text books for middle school students including the educational object of mathematics, and we characterized the definitions and kinds of mathematical teaching materials in middle school. With this preliminary investigation, we have established a developmental proposal of mathematical teaching materials in connection with the contents of textbook showing the kind of material and how to make the materials in detail. The proposal contains the educational object for each unit, the name of materials, contents of teaching subject according to the grade of students, and we made a model of teaching plan with the mathematical teaching materials. Being our developmental proposal of mathematical teaching materials used in teaching math in the middle school, we expect some contribution for the improvement of quality in math education. We hope that this research brings the growing of students' interest learning mathematics and the ability of observing, understanding, and thinking in the middle school.
