Social Media transformed the mass media based information traffic, and it has become a key resource for finding value in enterprises and public institutions. Particularly, in regards to disaster management, the necessity for public participation policy development through the use of social media is emphasized. National Disaster Management Research Institute developed the Social Big Board, which is a system that monitors social Big Data in real time for purposes of implementing social media disaster management. Social Big Board collects a daily average of 36 million tweets in Korean in real time and automatically filters disaster safety related tweets. The filtered tweets are then automatically categorized into 71 disaster safety types. This real time tweet monitoring system provides various information and insights based on the tweets, such as disaster issues, tweet frequency by region, original tweets, etc. The purpose of using this system is to take advantage of the potential benefits of social media in relations to disaster management. It is a first step towards disaster management that communicates with the people that allows us to hear the voice of the people concerning disaster issues and also understand their emotions at the same time. In this paper, Korean language text mining based Social Big Board will be briefly introduced, and disaster issue detection model, which is key algorithms, will be described. Disaster issues are divided into two categories: potential issues, which refers to abnormal signs prior to disaster events, and occurrence issues, which is a notification of disaster events. The detection models of these two categories are defined and the performance of the models are compared and evaluated.

To evaluate the relationship between the growth hormone 1 (GH1) T1663A polymorphism, recreational physical activity and body mass index (BMI) with reference to breast cancer, we conducted a case-control study with 669 cases of breast cancer and 682 population-based controls in Jiangsu Province, China. A structured questionnaire was used to elicit detailed information. All subjects completed an in-person interview. GH1 genotypes were identified using PCR-RFLP methods. Odds ratios (ORs) were estimated with an unconditional logistic model. The distribution of GH1 genotypes was not significantly different between controls and cases ($x^2$=2.576, P=0.276). Results of stratified analysis by the participation status of the recreational physical activity showed that the persons with GH1 A allele were at a decreased risk of breast cancer (adjusted-OR=0.66; 95% CI, 0.50-0.87) only among inactive individuals. Stratified analysis by BMI showed that the genotype A/A was associated with a decreased risk of breast cancer only among individuals of the BMI <25 (adjusted-OR=0.80; 95% CI, 0.66-0.98). The findings of this study suggest that recreational physical activity and BMI may modify any association between the GH1 T1663A polymorphism and breast cancer risk.

Facing the 21th century, the cultural era, a lot of people show much more concern on cultural products than before. These cultural products can be regarded as our national countenance because they might contain the national tradition and spirit. So, it is quite obvious that the image of a product will be directly related to the national image. The current problems of developing cultural products in Korea are underdeveloped product design and technique, and widespread of poor quality products. Fist of all, it needs to develop competitive designs by reflecting cultural aspects in each product, based on the specialized research and information on our culture. And it is important to invest in developing materials and skills for mass production and the improvement that can excel the past. Also, there are needs to reform the sales structure to connect producers and consumers directly, not through the wholesalers who cause the price rising. Finally, museums as well as government should cope with this cultural competitive era actively by giving the continuous cultural education and inducing the participation from citizens.

Purpose: This study aimed to examine the effect of spouses participating in health coaching on stage of the change, health behaviors, and physiological indicators among male office workers with cardiocerebrovascular disease (CVD) risk factors and compare the findings with trainers who provided health coaching only to workers. Methods: A quasi-experimental pretest-posttest design was used. Convenience sampling was used to recruit participants from a manufacturing research and development company in the city of Gyeonggi province. The health coaching program for the experimental group (n=26) included individual counseling sessions according to workers' stage of change, and provision of customized health information materials on CVD prevention to workers and their spouses for 12 weeks through mobile phone and email. Results: After 12 weeks of intervention, the total score for health behavior, and scores on the sub-areas of exercise and health checkups significantly improved in the experimental group, but there were no significant differences in the scores of stage of the change and physical indicators. The results of a paired t-test showed a significant decrease in the body mass index, abdominal circumference, systolic blood pressure, diastolic blood pressure, total cholesterol and triglyceride values, and a significant increase in the high-density lipoprotein cholesterol value in the experimental group after the intervention. Conclusion: To improve the health of male workers with CVD risk factors in the workplace, sharing health information with their spouses has proven to be more effective than health coaching for only workers. Therefore, it is important to develop strategies to encourage spousal participation when planning workplace health education for changing health-related behaviors.

Deciding on an optimal sensor placement (OSP) is a common problem encountered in many engineering applications and is also a critical issue in the construction and implementation of an effective structural health monitoring (SHM) system. The present study focuses with techniques for selecting optimal sensor locations in a sensor network designed to monitor the health condition of Dalian World Trade Building which is the tallest in the northeast of China. Since the number of degree-of-freedom (DOF) of the building structure is too large, multi-modes should be selected to describe the dynamic behavior of a structural system with sufficient accuracy to allow its health state to be determined effectively. However, it's difficult to accurately distinguish the translational and rotational modes for the flexible structures with closely spaced modes by the modal participation mass ratios. In this paper, a new method of the OSP that computing the mode shape matrix in the weak axis of structure by the simplified multi-DOF system was presented based on the equivalent rigidity parameter identification method. The initial sensor assignment was obtained by the QR-factorization of the structural mode shape matrix. Taking the maximum off-diagonal element of the modal assurance criterion (MAC) matrix as a target function, one more sensor was added each time until the maximum off-diagonal element of the MAC reaches the threshold. Considering the economic factors, the final plan of sensor placement was determined. The numerical example demonstrated the feasibility and effectiveness of the proposed scheme.

Climate change is tough global issue with human being to tackle in cooperative manners, because climate change affects globally and has long-term detrimental impacts. To get a clue to this intricate problem, vertical governance (global, regional, national, and local) with horizontal governance should be well orchestrated. In this research, we analyzed about 24,000 articles in Korean daily newspapers from 1990 to 2018 to find out vertical and horizontal governance characters of Korean climate change. The result showed that Korean government followed the global issues but lacks relations with neighbor countries. and found a little actions in local government. In horizontal governance aspect, Korean government approached the climate change as a tool for economic development and lead the issues without communication with other two player which are market and civil society. We proposed to use market mechanism to facilitate the participation and Climate Change Framework Act to setup the mechanism for cooperation.

With its technical development, digital printing is being universally introduced to the mass production of clothing factories. At the same time, many fashion platforms have been made for customers' participation using digital printing, and a tool is provided in platforms for customers to make designs. However, there is no sufficient solution in the production stage for automatically converting a customer's design into a file before printing other than designating a square area for the pattern designed by the customer. That is, if 30 different designs come in from customers for one shirt, designers have to do the work of reproducing the design on the clothing pattern in the same location and in the same angle, and this work requires a great deal of manpower. Therefore, it is necessary to develop a technology which can let the customer make the design and, at the same time, reflect it in the clothing pattern. This is defined in relation to the existing clothing pattern with digital printing. This study yields a clothing pattern for digital printing which reflects a customer's design in real time by matching the diagram area where a customer designs on a given clothing model and the area where a standard pattern reflects the customer's actual design information. Designers can substitute the complex mapping operation of programmers with a simple area-matching operation. As there is no limit to clothing designs, the variousfashion design creations of designers and the diverse customizing demands of customers can be satisfied at low cost with high efficiency. This is not restricted to T-shirts or eco-bags but can be applied to all woven wear, including men's, women's, and children's clothing, except knitwear.
