Recently, public safety services have attracted significant attention for their ability to protect people from crimes. Rapid detection of dangerous situations (that is, abnormal situations where someone may be harmed or killed) is required in public safety services to reduce the time required to respond to such situations. This study proposes a novel danger detection technology based on multimodal data, which includes data from multiple sensors (for example, accelerometer, gyroscope, heart rate, air pressure, and global positioning system sensors), and multilog data, which includes contextual logs of humans and places (for example, contextual logs of human activities and crime-ridden districts) over time. To recognize human activity (for example, walk, sit, and punch), the proposed technology uses multimodal data analysis with an attitude heading reference system and long short-term memory. The proposed technology also includes multilog data analysis for detecting whether recognized activities of humans are dangerous. The proposed danger detection technology will benefit public safety services by improving danger detection capabilities.

As the sustaindble development becomes the main goal of the global world in the 21st century, it is important that technological innovations should be realized ecologically sound based on co-evolutionalry approach. From this perspective, the trans-disciplinary research method is gaining importance in the evaluation process of public funded R&D, especially in the environmental technology. In our evaluation research on the R&D projects of the $CO_2$reduction and sequestration technology in Korea, we attempt to apply a trans-disciplinary integrated method on the concept of the eco-innovation, the technology push and the market pull. Also, we try to develop the trans-disciplinary indicators of the environmental technology evaluation. This research confirms the necessity of trans-disciplinary research among the three academic perspectives, engineering, social sciences and public policy.

본 연구는 우리나라에서 공공부문으로부터 기술이전을 받은 중소기업에 대한 사업화 성과와 이에 대한 영향에 관한 연구이다. 2014년 기술이전사업화조사분석자료집에 따르면 공공부문에서 기술이전을 받은 기술 중 약30%만이 활용되고 있고 나머지 70%는 미활용되거나 방치상태이다. 상대적으로 대학 및 출연연 등 공공기관의 기술사업화 지원 역량 또한 발전이 더딘 상황이다. 이에 따라 공공부문 기술사업화를 통해 중소기업의 발전을 추동하고, 혁신 성과를 확산하기 위해서는 지속적이고 체계적인 정책적인 지원이 필요한 상황이다. 본 논문에서는 공공부문 기술이전 이후 중소기업의 활용 및 사업화 등에 관한 전주기적 분석을 통해 사업화 성공과 실패 요인을 조사하였다. 최근 3년간 진행된 중소기업기술통계조사를 기반으로 하여 기술사업화 성공기업을 도출하고, 기술사업화의 활용형태에 따라 성과에 어떤 영향을 미치는지 분석을 하였다. 통계 분석 결과, 공공기술을 기반으로 한 사업화 성공 중소기업은 기술개발 성공건수 및 지식재산 등록건수가 많아질수록 사업화 성공률에 긍정적인 영향을 미쳤다. 또한 불필요하게 많은 기술개발, 계획 단계에서 긴 리드 타임 등의 경우 사업화 실패가능성이 높다는 것을 확인했다. 이러한 분석결과는 최근 양적인 차원에서 지원되는 중소기업의 기술개발 시도가 모두 긍정적인 효과를 발휘하기 어렵다는 정책 함의를 도출 할 수 있다. 또한 이를 위해 효율성 및 성공 가능성이 높은 기술사업화에 대한 선택적 지원이 필요하다는 것을 정책 함의로 도출할 수 있다.

Background: The possibility that electromagnetic fields (EMF) exposure may increase male breast cancer risk has been discussed for a long time. However, arguments have been presented that studies limited by poor quality could have led to statistically significant results by chance or bias. Moreover, data fo the last 10 years have not been systematically summarized. Methods and Results: To confirm any possible association, a meta-analysis was performed by a systematic search strategy. Totals of 7 case-control and 11 cohort studies was identified and pooled ORs with 95% CIs were used as the principal outcome measures. Data from these studies were extracted with a standard meta-analysis procedure and grouped in relation to study design, cut-off point, exposure assessment method, adjustment and exposure model. A statistical significant increased risk of male breast cancer with EMF exposure was defined (pooled ORs = 1.32, 95% CI = 1.14-1.52, P < 0.001), and subgroup analyses also showed similar results. Conclusions: This meta-analysis suggests that EMF exposure may be associated with the increase risk of male breast cancer despite the arguments raised.

The liver fluke Opisthorchis viverrini is a serious health problem in Thailand. Infection is associated with cholangiocarcinoma (CCA), endemic among human populations in northeast and north Thailand where raw fish containing fluke metacercariae are frequently consumed. Recently, Thailand public health authorities have been organized to reduce morbidity and mortality particularly in the northeast through O. viverrini and CCA screening projects. Health modification is one of activities included in this campaign, but systemic guidelines of modifying and developing health behavior among liver fluke and CCA prevention in communities towards health belief and social support theory are still various and unclear. Here we review the guidelines for modifying and developing health behavior among populations in rural communities to strengthen understanding regarding perceived susceptibility, severity, benefits, and barriers to liver fluke and CCA prevention. This model may be useful for public health officers and related organizations to further health behavior change in endemic areas.

Cancer is a menace fast gaining momentum in Nigeria and other developing countries. It is an expensive disease requiring a major financial and human resources for prevention, diagnosis and treatment. With no national policy on cancer control in the conntry, incidence (111.7/100,000 population) and mortality (86.6/100,000) rates in Nigeria are spiraling beyond control. This literature search study was primarily aimed at providing recommendations on cost-effective strategies for development interventions to promote self-management for cancer survivors in Nigeria with a goal to improve quality of life and overall survival.

Authors carried out the research on the actual condition of intensifying screens in a certain hospital and obtained the results as follows: 1. High speed intensifying screens were 63.9% and medium typed screen had 36.1%. 2. Half the number of using screens(51.5%) were not clear in a period of used time. 3. 47.4% of same typed screens showed a remarkable difference(two times) in sensitivity.

The development technology is not brought out the change of life style but space. According to the development technology, it is comes to an age of Ubiquitous computing that make the possible intelligent space. Space in public library, too, is necessarily changed according to introduce Ubiquitous technology. This change of space give a benefits to user in public library. Therefore finding solutions for user-centered space in public library is the purpose of this study as making it intelligently and sufficiently.

For evaluating the radiological safety of dismantled concrete, the process of disposal and recycling of the radioactive concrete generated during the dismantling of Kori Unit 1 is analyzed. Four scenarios are derived based on the analysis of the concrete recycling and disposal process, and the potential exposure to the workers and public during this process are calculated. VISIPLAN and RESRAD code are used for evaluating the dosages received by the workers and public in the following four scenarios: concrete inspection, transport of concrete by the truck driver, driving on a recycled concrete road, and public living near the landfilled concrete waste. Two worker exposure scenarios in the processing of concrete and two public exposure scenarios in recycling and disposal are considered; in all the scenarios, the exposure dose does not exceed the annual dose limit for each representative.
