  • This study was presented the small action by the budge sonance function. An estimation of budge sonance function was acquired displacements across all condition with a variation of small action. The budge sonance function was to be indicated to express the flow rate of body motion. Their function was suggested an issue of the action condition by budge sonance. This system was proposed a combination of the body motion and small action. The acquired sonance signal was to render the small action of body motion with budge sonance function. The analysis of budge function was generally realized a variation from displacements on the fast body motion. Budge sonance signal of action that vision condition was acquired to a variation of the $Vi-{\beta}_{AVG}$ with $(-4.954){\pm}(-5.42)$ units, that vestibular condition was acquired to a variation for the $Ve-{\beta}_{AVG}$ with $(-2.288){\pm}0.212$ units, that somatosensory condition was acquired to a variation for the $So-{\beta}_{AVG}$ with $(-0.47){\pm}0.511$ units, that CNS condition was acquired to a variation for the $C-{\beta}_{AVG}$ with $(-0.171){\pm}(-0.012)$ units. Budge sonance function was proposed the small action from axial action on body control. We know a body motion response from axial action was not only variation of budge sonance, but also body motion of fast body motion.

  • This study was compared the variation system of body posture condition for stability by the posture. We used a model of bio parameter on the basis of the move state in the standing posture. We compared the sway movement derived from average of the physical sensing condition. Vision condition of variation average (Vi-${\sigma}_{AVG-AVG}$) was verified slightly greater at $13.746{\pm}4.05$ unit. Vestibular condition of variation average (Ve-${\sigma}_{AVG-AVG}$) was verified slightly larger at $7.829{\pm}1.071$ unit. Somatosensory condition of variation average (So-${\sigma}_{AVG-AVG}$) was verified slightly smaller at $2.592{\pm}0.538$ unit. CNS condition of variation average (C-${\sigma}_{AVG-AVG}$) was verified slightly larger at $0.46{\pm}0.105$ unit. The valuation system will be to deduce the model of body management with falling and stroke and all that sort of things. There will be to infer a data algorithm and the evaluation of processing system.

  • To compare body signal, was designed the F-B function system on the body movement for the comfortable state. To detect subject of the normal state, was decided on the base of physical signal in the body movement. There are to detect the condition of Vision, Vestibular, Somatosensory and CNS. Vision condition was verified a variation of greater average (Vi-${\Phi}_{AVG-AVG}$) was presented slightly greater at $17.424{\pm}9.65$ unit. Vestibular condition was identified a variation of slightly greater average (Ve-${\Phi}_{AVG-AVG}$) was presented at $9.068{\pm}1.478$ unit. Somatosensory condition was checked a variation of smaller average (So-${\Phi}_{AVG-AVG}$) was presented slightly smaller at $2.79{\pm}0.419$ unit. CNS condition was confirmed a variation of diminutive smaller average (C-${\Phi}_{AVG-AVG}$) was presented slightly larger at $0.557{\pm}0.153$ unit. As the model depends on the F-B function system of body movement, average values of these perturbation were computed F-B function comparison data. These systems will be to infer a data algorithm and a data signal processing system for the evaluation of the stability.

  • 뇌-컴퓨터 인터페이스(BCI: Brain Computer Interface)는 뇌파를 활용하여 뇌의 활동이 컴퓨터에 직접 입력되어, 마우스나 키보드 같은 입력장치가 없이도 컴퓨터와 커뮤니케이션을 할 수 있는 장치를 말한다. 뇌파 인터페이스 관련 하드웨어제작기술이 발전함에 따라 고가이면서 대형이었던 뇌파측정장비가 최근에는 소형화되고 저렴한 가격대로 출시되면서 앞으로 다양한 멀티미디어 분야에서 응용이 될 것으로 예상된다. 본 논문은 BCI의 다양한 연구 가운데 일반인들이 가장 먼저 접할 수 있는 응용영역인 게임에 대하여 BCI가 어떻게 적용되고 있는지 현재까지의 국내외 기술수준과 동향을 파악하고자 한다. 다음으로 BCI를 사용한 게임의 문제점을 살펴보고 향후 국내 BCI 연구 및 개발방향을 제시하고자 한다.

  • Recently, the demand to acquire and improve durability performance has steadily risen in rubber components design. In design process of a rubber component, an analytical prediction is the most effective way to improve fatigue life. Existing methods of analytical estimation have mainly used an equation for fatigue life obtained from fatigue test data. However, such formula is rarely used due to costs and time required for fatigue testing, as well as randomness of rubber materials. In this paper, we describe fatigue life estimation of rubber component using only the results from a relatively simple tearing test. We estimated fatigue life of the Janggu type fatigue specimen and the automotive motor mount, and evaluated reliability of the proposed method by comparing the estimated values with actual test results.

  • In this study there was the analysis of government incentives and resident support of public crematoriums, typically identified in Korea as a locally unwanted land use (LULUs), in the metropolitan area. The study looked at what government programs would be potential incentives for allowing the crematoriums to exist in metropolitan communities. Such programs were diverse, with projects focused on: enhancing resident welfare, increasing resident income, funeral facilities and management consignment, community oriented programs, education, funding, and others. Among them, it was found that residents were most in support of programs for enhancing resident welfare and increasing income among residents. In order to resolve the complexities of community support for LULUs and government incentives to shift public perception of cremation, three main policies are proposed. First, it would be necessary to compliment additional project support policies which provide medical services, resident prefered projects, and improvement of substandard housing. Second, it would be important to establish ordinances concretely identifying residential support projects based on community needs assessment. Lastly, it would be of the government's best interest to build policies for resident supported projects that reflect local conditions and the residents' demands for allowing non-preferred facilities to be built, and then to analyze the economic feasibility of these demands.

  • This study analyzed the digital divide of Korean senior citizens through the preference for smart media. Targeting two media out of mobile internet and mobile social media, the media dependency ratio and the trend of people in their 20s-60s were verified. Regarding the dependency ratio of young people(20s) and senior citizens(60s), in case of mobile internet, people in their 60s were average 8.6% while people in their 20s were average 38.9%, so that the ratio of senior citizens was lower by 30.3%. In case of social media, people in their 60s were average 1%, which was 7.1% lower than people in their 20s(8.1%). And this divide was the digital divide shown in the informatization process through the trend of internet use of senior citizens in their 60s or up. Thus, as the policy measures for solving the digital divide of senior citizens, it would be required to continuously develop the digital cultural programs for senior citizens, to expansively perform the government subsidiary policies like additionally providing the essential information to senior citizens, and also to expand the smart-based infrastructure for senior citizens' participation in economic activities.

  • This study found the digital divide of Korean elderly persons on the basis of the 2013-2017 survey data of the perception of media information adopters. The studied media were traditional ones, such as newspaper and TV. The media dependence of those in their 20s to 60s was compared and analyzed. As a result, regarding their dependence on newspaper, elderly persons in their 60s had 20.7% on average, 13.6% higher than the percentage (7.1%) of young persons. Regarding their dependence on TV, those in their 60s had 97.6% and those in their 20s had 63.7%, so that there was a wide gap of 33.9% on average. The smartphone penetration rate of those in their 60s was 61.3%(2015-2017) on average, which tended to rise. The elderly's dependence on traditional media featured Digital Divide which is found in the informatization process. Accordingly, in order to solve their digital divide, it is required to expand education in line with their knowledge level through remote online centers, develop inclusive ICT for convenience, and change philosophical policy paradigm in the dimension of quality of life.

  • 반려인 들이 늘어나고 반려동물 시장이 크게 증가하고 있으나, 반려동물의 장례 관련 연구는 미비하다. 반려동물 장례의 성장가능성을 타진하고자 반려동물 장례에 대한 인식을 설문을 통하여 조사하였다. 조사 결과 긍정적 인식에 영향을 미치는 요인으로 반려동물 유무, 연령, 종교, 결혼 유무 등이 있었다. 인식조사 결과에서 반려동물 장례에 대한 인식은 긍정적이었으나, 현재 이를 수용할 반려동물 장례에 대한 준비는 미흡하다. 본 연구를 통해 국내 반려동물 장례의 증가가 예상됨에 따라 반려동물의 장례와 사체처리를 동물보호법 상으로 통합하고, 반려동물 장례관련 대책마련과 체계화된 반려동물 전문 장례인력 육성에 힘써야 할 것이다.
