Background Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life. Methods A prospective review of all upper-arm transradial amputation amputees who used 3D-printed myoelectric interface prostheses (Mark V) between January 2016 and August 2017 was conducted. The functional outcomes of prosthesis usage over a 3-month follow-up period were measured using a validated method (Orthotics Prosthetics User Survey-Upper Extremity Functional Status [OPUS-UEFS]). In addition, the correlation between the length of the amputated radius and changes in OPUS-UEFS scores was analyzed. Results Ten patients were included in the study. After use of the 3D-printed myoelectric single electromyography channel prosthesis for 3 months, the average OPUS-UEFS score significantly increased from 45.50 to 60.10. The Spearman correlation coefficient (r) of the correlation between radius length and OPUS-UEFS at the 3rd month of prosthetic use was 0.815. Conclusions This low-cost 3D-printed myoelectric-interface prosthetic hand with a single reliable myoelectrical signal shows the potential to positively impact amputees' quality of life through daily usage. The emergence of a low-cost 3D-printed myoelectric prosthesis could lead to new market trends, with such a device gaining popularity via reduced production costs and increased market demand.

Innovation of genomics technology has recently been extended to Direct To Consumer Genetic Test (DTC-GT) which consumers purchase without requesting the service on medical institutes. In 2016, Korea has introduced the DTC-GT but the market size is small comparing to global market. This study analyzes consumers' purchase intentions and purposes and their influential factors based on 2018 consumer survey. According to the results of binominal and multinominal logistic regression, knowledge after purchase, attitude on medical care benefit, health status are statistically significant on purchase intentions. Purchase purposes are different on age group and related on medical care rather than health care. These results imply that DTC-GT is needed to improve consumer satisfaction, re-purchase and effective care service. This paper is expected to contribute on strategic directions for the new DTC-GT product development.

The "Internet of things" (IoT) is becoming an increasingly growing topic of conversation, it is a new emergent technology that can be present in almost every field and application. It's a concept that not only has the potential to impact how people live but also how people work. Broadband Internet and Mobile Internet are becoming more widely available, the cost of the service is decreasing, more devices are being created with Wi-Fi capabilities and sensors built into them, technology costs are going down, and smartphone penetration is growing so fast. All of these facts are creating the best environment for the IoT applications. In a country like Ecuador, is important to have a previous analysis about the feasibility of the implementation of this new technology in order to know what are the challenges the country has to face, and also to not stay behind as the other countries in the region are advancing. Currently, this kind of analysis does not exist. The Internet of Things is an innovation where business and technology models in Ecuador are relatively unexplored. The current infrastructure deployed in Ecuador and the available devices in the market are the central facts to initiate with the research, which is a starting point to show if Ecuador is ready to this technology, and if is not ready what is missing. This study shows the current telecommunications status in Ecuador, and its strengths and weaknesses to start the deployment of Internet of Things. Besides, it also will show the most likely applications that can be easily adopted for the Ecuadorian market with its respective availability, affordability, and adaptability.

The aim of this study is to improve the "empty house problem" in Korea. The direction of improvement of systems in Korea was considered and compared with empty house systems in the United Kingdom, France, Germany, the United States, and Japan. Korea's system is based on comprehensive regulations centered on the demolition of empty houses. To actively solve the problem of unoccupied houses, detailed guidelines are needed, which must consider the current status and surrounding environment of empty houses. There should be institutional grounds for local governments to actively intervene in the issue of empty houses, and there should be a system that enables tax and cost support for the reuse of such houses. An information sharing system is also needed for sharing empty house information among local governments. To utilize empty houses as resources for the housing market, it is necessary to establish a consultative system consisting of residents, urban and architectural experts, and private businesses.

In this paper, we explore market and environmental factors which affecting organization's priority claim application which is more powerful and prompt strategic method to protect technology from competitors under uncertain and volatile environments. This study empirically examines why organizations strategically choose the priority claim application which is more strong tactics to protect technology as the source of sustainable competitive advantage. We suggest that market and environmental factors, such as exogenous shock, volatility, and uncertainty, may also affect strategic decision that organization take patent application with claiming priority. The results of our analysis of priority claim application in the Korean high-tech electronics industry from 1994 to 2008 showed that these three strategic factors affected the technology protection decision and organization's status also moderate theses effects, as predicted in our hypotheses.
