Criticism has been raised that the way of teaching weights in the 3rd and 4th graders of elementary school is different between the 2015 revised math curriculum and the 2015 revised science curriculum, causing confusion among elementary school teachers and students. This study tried to confirm the social recognition that should be considered in the process of didactic transformation which means transformation from knowledge to used into knowledge to taught and to compare the variations of didactic transformations differently according to didactic intentions. The research analyzes and synthesizes the root of the meaning of weight, weight in the international standard system of units SI, weight implemented in Korean mathematics curriculum and textbooks, Singaporean mathematics curriculum and textbooks, USA mathematics curriculum and textbooks, and Korean science curriculum and textbooks. Through this analysis, a pedagogical perspective on how to define and teach weight in elementary school as knowledge to be taught was derived.

This study aims to understand the process of valuing contemporary artworks by young and emerging artists via online art platforms. This paper conceptualizes Bourdieu's theory of cultural capital, which theoretically guides us for conducting a case study of Saatchi Art. This article mainly collected data by interviewing seven Korean artists who were selected by our case with the supplement information carried out direct observation and document reviews. By analyzing the gathered data, the key finding of this research is that the selection of artists in Saatchi Art's curatorial program implicitly admits and guarantees the value of their artworks. By doing so, it contributes to building symbolic capital for the selected artists. This article also contends that such construction of the artists' symbolic capital results from the accumulated symbolic capitals of the founder and curator of the online platform. The theoretical contribution of this paper is to expand previous research on valuing artworks in the offline art world into the online one.

The prime cause of yield reduction of sesame is the lodging-induced damage, so a study of analyzing the products of sesame and frequency of a strong wind with the relation was implemented. The regression significance between the maximum velocity of wind during growing period of sesame and products was the highest in the Mokpo, Hampyung, Haenam, and Kohung district of coast but inland districts of Kwangju was non-significant. Estimated degrees of lodging-induced damage by a strong wind was shown as generally 31-41%, but a exceptional degree was observed as high as 80.5% at Mokpo district.

유구한 전통을 배경으로 우리나라는 유네스코 세계기록유산을 세계 4위, 아시아 1위로 등재하여 기록물의 가치를 국제적으로 인정받고 있다. 이제는 세계 기록유산 16건이라는 등재 수량을 넘어, 활용도 증진을 통한 명실상부 질적 차원의 우수 세계 기록유산 보유국가로 성장해야 할 시기를 맞고 있다. 이러한 측면에서 기록유산의보편적 접근과 활용의 증진을 목적으로 하는 국제기록유산센터(ICDH, International Centre for Documentary Heritage)의 2019년 청주시 유치는 시사하는 바가 크다. 또 정부가 세계 기록유산의 다양한 활용 제고를 위한 지자체 협업 사업을 지원하기 시작한 것도 유의할만하다. 그러나 한국 천문학 분야에서는 세계 기록유산이 한 건도 지정되지 않아 우리나라의 우수한 과학적 성취가 담긴 사료들은 알려지지 않고 있으며, 체계적인 관리·보존도 미비한 상태다. 이에 이 연구는 한국 천문학 기록자원의 세계 기록유산 발굴과 등재 및 등재 이후 활용 증진을 위한 아웃리치 서비스의 방법론을 제언하는 데 목적을 가지며 다음 기획론을 제시하고자 한다. 먼저 한국 천문학 기록자원의 세계 기록유산 발굴을 위하여 유네스코의 등재평가기준과 참고할만한 등재과정의 선행사례를 분석한다. 다음으로, 등재 이후 정·관·학 협업의 체계적 관리보존과 공유체계를수립하는 방안을 모색하고자 한다. 이를 위하여 소장처와협업체간 분쟁의 소지가 될 수 있는 저작권 등 위험 요소와 참고할만한 국내외 협업의 선진사례를 분석한다. 마지막으로 한국 천문학계의 요구와 현실에 부합하는 기록학적방법론을 분석하여 한국 천문학 분야 세계 기록유산의 아웃리치서비스 방안을 제언하고자 한다. 이 연구는 천문학 분야에서 망실·훼손될 수 있는 기록 자원을 발굴하는 계기를 세계 기록유산에서 찾아, 천문학계에 새로운 연구의 장(場)을 창출하는 선순환을 도모했다는 점에서 의의가 있다. 그러나 선험적 기획이므로 과정상 발생할 수 있는 변수의 대처 방안과 유의성 분석 등 연구 결과 검증에는 한계가 있다. 향후 한국 천문학과의 협업으로 세계 기록유산과 관련한 사료 발굴과 가치 고증 등 학술적 이론 검증을 이어나가 다양한 학제 간 연구로 심화하길 기대한다.

This study aimed to investigate the social consequences of happiness. For this purpose, we examined the effect of happiness on the formation of adolescents' peer relationship. A total of 241 Korean junior high school students completed a happiness questionnaire consisting of subjective well-being, psychological well-being, self-esteem, and optimism at the beginning of the school year. Four months later, their popularity and social behaviors were measured using self-reports and peer-nomination measures. Happy male students were more likely to become nominated as a preferred friend by their peers at the end of the semester; happy females were evaluated by their peers as being more creative than others. Happy adolescents also viewed themselves as being more sociable, popular, and having more leadership than others. Overall, the findings imply that happiness also have positive social consequences in highly collectivist cultural settings, such as Korea.

This paper attempts to identify that the speeding behavior is the important factor in traffic accident by analysing the background and process of speeding behavior. The structure of hurried behavior is reviewed to explain the relationship between the speeding behavior and hurried behavior. And the process of speeding behavior which becomes his own attitude and behavior in driving by social customs approval is analysed by risk homeostasis theory. The results of attitude survey show that drivers speeding behavior is not changing even though they know that speeding behavior is main factor in traffic accident. The influence structure among hurried behavior, background and process of speeding behavior should be analysed to understand the actual speeding behavior in driving.

In an effort to discover new technologies and to forecast social changes of technologies, a number of technology life-cycle models have been developed and employed. The hype cycle, a graphical tool developed by a consulting firm, Gartner, is one of the most widely used models for the purpose and it is recognised as a practical one. However, more research is needed on theoretical frames, relations and empirical practices of the model. In this study, hype cycle comparisons in Korean and global search websites were performed by means of web-search traffic which is proposed as an empirical measurement of public expectation, analysed in a specific product or country in previous researches. First, search traffic and market share for new cars were compared in Korea and the U.S. with a view to identifying differences between the hype cycles in the two countries about the same product. The results show the similarity between the two countries with the statistical significance. Next, comparative analysis between search traffic and supply rate for several products in Korea was conducted to check out their patterns. According to the analysis, all the products seem to be at the "Peak of inflated expectations" in the hype cycles and they are similar to one another in the hype cycle. This study is of significance in aspects of expanding the scope of hype cycle analysis with web-search traffic because it introduced domestic web-search traffic analysis from Naver to analyse consumers' expectations in Korea by comparison with that from Google in other countries. In addition, this research can help to explain social phenomina more persuasively with search traffic and to give scientific objectivity to the hype cycle model. Furthermore, it can contribute to developing strategies of companies, such as marketing strategy.

The investment in healthcare industry has recently increased not only for global ventures but also for the domestic ventures. However, there has been hardship of founding and investment caused by healthcare startups characteristics that are costly and time consuming. In this study, the applicability of 'Lean Startup' theory to healthcare ventures was explored through the case of a domestic startup which accomplished funding from VC and KOSDAQ after establishing based on its technology in healthcare industry. There have been numerous case studies that applied 'Lean Startup' to IT industry. However, this case study that applied 'Lean Startup' to healthcare industry have some implications as follow: First, it is critical to conduct a hypothesis testing at initial research stage through R&D of 'MVP' (Minimum Viable Product) as the prototype testing is strictly prohibited in healthcare industry. Second, healthcare R&D teams ought to be well organized as startup teams and all researchers should be equipped with entrepreneurship as the licensing process in healthcare industry is time-consuming and costly due to issues like clinical studies. Lastly, management skills as smart and light as 'Lean Startup' are required in order to encourage young engineers' technology startups.
