Due to the high increment in usage and built-in advanced technology of smartphones, human activity recognition relying on smartphone sensor data has become a focused research area. In order to reduce noise of collected data, most of previous studies assume that smartphones are fixed at certain positions. This strategy is impractical for real life applications. To overcome this issue, we here investigate a framework that allows detecting the status of a traveller as idle or moving regardless the position and the direction of smartphones. The application of our work is to estimate the total energy consumption of a traveller during a trip. A number of experiments have been carried out to show the effectiveness of our framework when travellers are not only walking but also using primitive vehicles like motorbikes.

Globally, cancer research has been considered one of the most important field of biomedical researches. Recently, in Korea, there are increasing concerns about cancer research and the development of national cancer control programme. For the efficient investment in cancer research at the national level, strategic approach is needed based on the nationwide information about current status of research. However even the basic data on cancer research have not been systematically collected, and are not available when necessary. The aim of this study is to assess current status of cancer research. For this purpose, this study applied two round Delphi method in which fifteen experts in cancer research fields participated. They rated each items on the initial list at the first round, and modified their responses at the second round. Panels responded that pathogenesis of cancer, research & development of cancer drug, and oncogene, etc. are the most urgent and important research Holds. They assessed national level of cancer research as being 49.6% of the world highest level. Coefficient of variation tended to be lowered with the iteration. Predictive stability was evaluated to be lower in items of urgency than in items of importance and research level. Although this study shares the same limitations in the selection of the experts with many other Delphi studies, it provides a primary data that would be required to plan the national strategy of the cancer research.

It is time for environmental educators to think about corporations and it is also time for corporations to consider about the environment and EE(environmental education). However there is very little research that discusses the importance of corporation's involvement in EE. Therefore, the purpose of this paper is to review the research of corporate environmental education. The main aim of this paper is to disclose the research trend, result of corporate EE. To do this, environmental education journals and books, published in Korea and oversea, are reviewed. However, there is very little research and are a few articles focused on corporate EE, which mainly conducted in Japan. Furthermore, these articles usually introduce the status and cases of corporate EE. As a results this article analysed that the main themes of the researches of corporate EE are the possibility of corporate EE, the status of corporate EE, the collaboration between school and corporation, the effect of corporate EE, and the limits and challenges of corporate EE. Also some important results of these themes are introduced and discussed for the application in Korea.

Rapid development of information and communication technology is leading the digital transformation (hereinafter, DT) of various industries. At this point in rapid online transition, fashion manufacturers operating offline-oriented businesses have become highly interested in DT and artificial intelligence (hereinafter AI), which leads DT. The purpose of this study is to examine the development status and application case of AI-based digital technology developed for the fashion industry, and to examine the DT stage and AI application status of domestic fashion manufacturers. Hence, in-depth interviews were conducted with five domestic IT companies developing AI technology for the fashion industry and six domestic fashion manufacturers applying AI technology. After analyzing interviews, study results were as follows: The seven major AI technologies leading the DT of the fashion industry were fashion image recognition, trend analysis, prediction & visualization, automated fashion design generation, demand forecast & optimizing inventory, optimizing logistics, curation, and ad-tech. It was found that domestic fashion manufacturers were striving for innovative changes through DT although the DT stage varied from company to company. This study is of academic significance as it organized technologies specialized in fashion business by analyzing AI-based digitization element technologies that lead DT in the fashion industry. It is also expected to serve as basic study when DT and AI technology development are applied to the fashion field so that traditional domestic fashion manufacturers showing low growth can rise again.

Somatic cell nuclear transfer (SCNT) for miniature pig has been developed for xenotransplantation and many other biomedical experiments. However, the efficiency of SCNT is still very low due to many factors. To optimize the surrogate mother condition for improvement of cloned miniature pigs efficiency, we investigated the effect of the status of surrogate mother on pregnancy, farrowed rate in SCNT pigs. After SCNT with mesenchymal stem cells as donor cells, the SCNT embryos were surgically transferred into the oviduct of surrogated pigs. To compare the effects of status of surrogate pigs on pregnancy, surrogate pigs were prepared by artificial abortion at day 20~29 (Group 1), 30~39 (Group 2), and 40~45 (Group 3) of gestation. After SCNT embryos transfer in three different status of surrogate pigs, Group 2 (56.3%) and 3 (55.6%) had significantly ($p$ <0.05) higher the pregnancy rate than group 1 (0%) at day 30 of gestation. The status of ovulation in surrogate pig also was investigated. Post-ovulation status (54.8%) had higher proportion than pre-ovulation status (38.7%) and ovulation status (6.5%). We obtained 19 cloned miniature piglets from seven surrogate gilts and five piglets are living healthy but fourteen piglets died soon after birth or stillbirth. The weights of piglets greatly differ from 254 to 1,296 g. Microsatellite analysis showed that cloned piglets were genetically different from the surrogate mother and cloned piglets were genetically equal to the donor cell. In conclusion, the present result indicates that artificially abortion method can improve the efficiency of pregnancy after SCNT in pigs. This study will provide available method for the further study and application in the field of xenotransplantation.
