박주영,이구연,강경태,Park, Ju-Yeong,Lee, Gu-Yeon,Gang, Gyeong-Tae 한국통신학회 2013 정보와 통신 Vol.30 No.10

최근 고령화 사회로 진입함에 따라 건강 상태 상시 모니터링에 대한 관심이 높아졌으며, 이에 편승하여 부정맥을 탐지하는 기법에 대한 연구도 활발히 진행되고 있다. 원격심전도 모니터링을 통해 병원 방문 없이도 진료 및 진단이 가능해 질 것으로 예측된다. 이러한 원격심전도 모니터링은 사이버물리시스템의 대표적인 응용사례에 해당된다. 본 고를 통해 우리는 원격심전도 모니터링 응용 사례를 물리시스템과 사이버시스템의 상호작용 관점에서 살펴보고, 이를 통하여 효율적인 시스템 설계 방안에 대하여 논한다.

We present results of Molecular Dynamics calculations on the behavior of liquid water droplets on hydrophilic and hydrophobic solid surfaces with random roughness according to droplet size. We investigate the effects on wetting characteristics such as contact angle, wetting radius and topography of water droplets. In this paper, random rough surfaces are defined in term of the standard deviation of the roughness height, σ, and autocorrelation length, L. These surfaces are generated by changing the standard deviation of the roughness height, σ, from 1 ? to 3 ?, as fixing the autocorrelation length, L. The water droplet sizes are considered in range from2000 to 5000 molecules. The Lennard-Jones potential energy model is adopted as the interaction model between water droplets and solid surfaces molecules. The contact angles are increased as a standard deviation of the roughness height, σ and a water droplet size are increased.

The intention of human activity recognition systems is to build a system that can automatically understand a range of predefined activities from the sensor signals. The activity recognition system need to be developed in two fields: feature extraction algorithm from sensor data and classifier. In this study, we present the combination of various time domain features and periodic feature to get optimum feature from the sensor signals. An Artificial Neural Net (ANN) with Scaled Conjugate Gradient (SCG) algorithm has been employed to classify different human activities. For the experiments we constructed a database with five activities such as power walking, jogging, running, standing and walking using a multi-sensor module which is structured as a mobile phone form. Further, two static locations such as hand and pocket were used as a sensor module position. The experimental results showed that the average accuracy of human activity recognition system was about 99.4% from five activities.

Objectives The objective of this study is to determine the antimicrobial effect of Daehwanggyeonu-san(Dahwangqianniu-san,DGE) and synergistic effects with antibiotics oxacillin, ampicillin, and gentamicin against Methicillin-Resistant Staphylococcus aureus( MRSA). Methods The antibacterial activity of DGE extract was evaluated againest MRSA strains by using the Disc diffusion method, broth microdilution method(minimal inhibitory concentration; MIC), checkerboard dilution test. The checkerboard dilution test was used to examined synergetic effect of oxacillin, ampicillin, gentamicin, ciprofloxacin with DGE extract. Results DGE showed antimicrobial activity against MRSA with an MIC value of 125∼250 μg/mL. In the checkerboard test, the interation of DGE with all tested antibiotics produced almost synergy or partial synergy against MRSA. Conclusions This study shows that DGE reduced the MICs of several antibiotics tested, and a remarkable antibacterial effect of DGE, with membrane permeability enhancers and ATP synthase inhibitors. This study can be a valuable source for the development of a new drug with low MRSA resistance. (J Korean Med Rehabil 2018;28(2):21-35)

목적 본 연구는 경상도 지역 작업치료사의 노인학대 인식과 목격실태를 조사하고자 한다. 연구방법 본 연구는 경상도 지역에서 근무하는 71명의 작업치료사를 대상으로 설문조사하였다. 수집된 자료는 SPSS18.0 통계프로그램을 사용하여 분석하였다. 모든 통계학적 유의수준은 p=.05로 하였다. 연구결과 작업치료사의 노인학대에 대한 관심은 보통 이하가 72.4%로 높지 않음을 알 수 있었다. 작업치료사는 신체적 학대를 가장 심한 학대로 인식하였고, 정서적 학대를 가장 덜 심한 학대로 인식하였다. 대상자의 91.5%가 노인학대를 목격한 경험이 있다고 응답하였으며, 방임과 재정적학대를 가장 많이 목격하고 있는 것으로 나타났다. 결론 본 연구 결과 작업치료사의 노인학대에 대한 관심과 인식은 미비하다. 앞으로 작업치료사 분야에서도 노인학대에 대한 연구가 활발히 진행되어야 할 것으로 사료된다. Objectives : This purpose of this study is to explore knowledge and conditions of elder ebuse of the occupational therapist in kyoungsangdo. Methods : A survey was provides to 71 occupational therapist in kyoungsangdo. The collected data was analyzed by SPSS 18.0 statistical program. All statistical significance level was to p=.05. Results : The occupational therapist is usually less than the interest elder abuse is not high as 72.4% was seen. Occupational therapists recognized physical abuse as the most severe abuse and emotional abuse as the slightest abuse. 91.5% of subjects witnessed elder abuse, the most frequent abuse was financial abuse and next neglect. Conclusion : Occupational therapist`s interest and awareness of elder abuse is the insufficient. And Actively progressed research on elder abuse should be considered in Occupational therapy.

This thesis is aimed for the comprehension of the impact of consecutive dance sport education on the body-consciousness and body-esteem. The subjects were the 7th and 8th graders of a middle school located in Seoul: 43 in the experiment group and 33 in the controlled group. The instruments used to implement the research are the questionnaire translated by Kang, Myung-ok, which Miller, Murphy and Buss developed for the measurement of body-consciousness and the one which Franzoi and Shieds developed for the measurement of body-esteem. SPSS Windows 10.0 was used for the process of the data of this thesis. Mean, the standard deviation, reliability analysis, frequency analysis, independence samples t-test, paired samples t-test are also implemented. The conclusions are as follows: First, there is some difference between those who major in dancing and those who don`t in terms of the body-consciousness and the body-esteem. The research shows that those major in dancing are higher in average in terms of the whole body-consciousness and the internal body-consciousness, external body-consciousness, body flexibility, body-esteem. All those factors show a distinctive difference. Second, there is a significant difference between the 7th graders and the 8th graders in terms of body-consciousness and body-esteem. The 8th graders are higher in the general physical consciousness and internal body-consciousness, external body-consciousness, body flexibility, sexual attraction, attention to weight, and physical condition. All these factors show a distinctive difference. Third, after the a consecutive 16 week dance sport education the subordinate factors such as internal body-consciousness, external body-consciousness, and body-flexibility as well as the whole body-consciousness show some difference between the two groups. The experiment group shows higher average than the controlled group in the whole body-consciousness and the subordinate factors such as internal body-consciousness, external body-consciousness, and body flexibility. All these variables have distinctive difference. Fourth, after the consecutive 16 week dance sport education the subordinate factors such as sexual attraction, attention to weight, body-condition as wall as the whole body-consciousness show a distinctive between those two groups. The average of the experiment group in the subordinate factors such as sexual attraction, attention to weight, body-condition as well as the whole body-consciousness is much higher than that in the controlled group. All these variables have distinctive difference. The result shows that the consecutive dance sport education influences on body-consciousness and body-esteem significantly and both those who major in dance and the 8th graders show higher average than those who don`t and the 7th graders respectively in terms of the consecutive dance sport education has a great effect on the increase of the female teenagers` self-confidence. The increase of body activity through the dance sport has positive effect on the body-satisfaction.

플라스틱과 무기성 폐기물을 이용한 탄소-철 복합체 및 합성가스 생산

권기훈 ( Gihoon Kwon ),박주영 ( Ju-yeong-park ),송호철 ( Hocheol Song ) 한국폐기물자원순환학회(구 한국폐기물학회) 2021 한국폐기물자원순환학회 춘계학술발표논문집 Vol.2021 No.-

플라스틱은 생산단가가 낮고 활용범위가 넓어 실생활과 산업 전반의 다양한 분야에서 널리 사용되고 있음. 플라스틱 사용량은 매년 증가하고 있으며 2018년에는 3억6천톤에 달하는 플라스틱이 생산됨(Statista report 2020. 특히, 코로나19로 인해 비대면 문화 확산으로 1회용 용기사용이 급증하고 있으며 이로 인해 2020년 상반기 플라스틱 배출량은 전년 대비 18% 증가함. 플라스틱은 생분해성이 낮고 연소 중 염소, 산소와 결합하여 다이옥신과 같은 유독성 물질을 만들기 때문에 매립이나 소각등 기존의 폐기물 처리공정으로 처리하는 데에는 한계가 있음. 지금까지는 주로 중국이나 필리핀으로의 수출을 통해 많은 양의 플라스틱을 처리해 왔으나 2021년 1월 1일부터 바젤협약 개정안(2019년 5월 채택)이 발효되어, 모든 폐플라스틱이 수출입 통제 대상 폐기물로 관리되게 됨. 이로 인해 단지 내 수집된 폐기물을 업자가 수거해가지 않으면서 플라스틱 폐기물에 대한 사회적 문제들이 대두되고 있음. 이러한 이유로 플라스틱을 효율적으로 처리하는 방안에 대한 연구들이 진행되고 있으며 그 중 플라스틱을 고부가가치 물질로 전환하려는 연구들이 주목을 받고 있음. 본 실험에서는 플라스틱의 열분해 공정에 무기성 자원(산업폐기물, 광물 등)을 사용하여 고체탄소의 수율을 높일 수 있는 연구를 수행함. 추가적으로 기존 플라스틱의 열분해 생성물인 합성가스의 수율에 미치는 영향을 조사함. 최종 물질은 탄소-철 복합체로서 다양한 공정에 활용될 수 있을 것으로 보임.
