생활 환경에서의 인공지능 시스템 성능 개선 및 평가를 위한 리빙랩 및 혼동 매트릭스

하지원(Ji-Won Ha),서지석(Ji-Seok Seo),이성수(Seongsoo Lee) 한국전기전자학회 2020 전기전자학회논문지 Vol.24 No.4

최근 들어 IoT와 스마트홈의 발전에 따라 낙상 사고 감지, 화상 위험 감지와 같이 일상 생활에서의 안전 감지 기능이 많이 보급되기 시작했다. 이러한 안전 감지 기능은 대부분 인공지능에 의해 수행된다. 그러나 실험실 환경에서 안전 감지의 정확도만 평가하는 경우에는 실제로 일상 생활 환경에서 체감하게 되는 성능과 꽤 큰 차이를 보이는 경우가 많다. 본 논문에서는 이러한 문제점을 보완하기 위해 사용하는 두 가지 기법인 리빙랩과 혼동 매트리스를 소개한다. 리빙랩은 단순히 일상 생활 환경의 모사를 넘어서 사용자가 직접 기술 개발 및 제품 설계에 참여할 수 있는 통로가 된다. 또한 혼동 매트리스에서 도출되는 다양한 성능 척도는 사용 목적에 적합하게 인공지능 시스템의 성능을 평가하는데 큰 도움을 준다. Recently, the daily life safety detection functionalities such as fall accident detection and burn danger detection are widely disseminated along with the development of IoT and smart home. These safety detection functionalities are mostly performed by artificial intelligence. However, simple accuracy measurement of the safety detection in laboratory environment is often far from practical performance in daily life environment. To mitigate this problem, this paper introduces two techniques, i.e. living lab and confusion matrix. Living lab is more than simple simulation of daily life environment, and it enables users to directly participate technology development and product design. Various performance measures induced from confusion matrix significantly help to evaluate the performance of artificial intelligence system for proper application purposes.

V2O5-WO3/TiO2/SiC 촉매필터의 NO 환원에 SO2와 H2O가 미치는 영향

하지원 ( Ji Won Ha ),최주홍 ( Joo Hong Choi ) 한국화학공학회 2014 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.52 No.5

촉매필터의 NO 환원활성을 조사하기 위하여 SO2와 H2O가 동시 또는 따로 존재하는 조건에서 NO, NH3, air로 구성된 합성가스 분위기에서 그 성능이 측정되었다. 집진성능이 높이 평가된 SiC 세라믹 필터의 기공에 V2O5-WO3/TiO2촉매를 코팅하여 SCR용 촉매필터를 제작하였다. 260 oC 이하의 저온영역에서 반응가스 중에 SO2와 H2O가 각각 또는동시에 존재할 경우에 이들이 존재하지 않을 때와 비교하여 촉매필터의 활성이 두드러지게 감소하였다. 반면에 320 oC이상의 고온에서는 반응가스 중에 SO2가 포함될 경우 촉매필터의 활성이 증가하여 여과속도 2 cm/s에서 500 ppm의NO를 99.8% 이상 질소로 환원시켰다. 특히 반응가스 중에 물이 존재할 때는 380 oC의 고온까지 99% 이상의 NO 전환율이 유지되었다. 이와 같은 물의 영향은 물이 고온에서 NH3 산화반응을 둔화시켜서 N2O 생성으로 가는 반응을 억제시키기 때문으로 해석되었다. SO2와 H2O가 공존하는 반응가스에서 100시간 운전 후에도 촉매필터의 초기 NO 환원활성이 유지되었다. 따라서 촉매필터가 분진과 NOx 가스를 동시에 처리할 수 있는 우수한 산업촉매로써 활용될 수있을 것으로 사료되었다. For investigating NO reduction activity of an catalytic filter, the catalytic performance was measured underthe presence of SO2 and H2O, respectively or simultaneously in the simulation gas composed of NO, NH3, and air. Thecatalytic filter was prepared by coating V2O5-WO3/TiO2 catalyst on the pore surface of SiC filter element of which thesuperior performance for the particulate removal was well known. At the temperature below 260 oC, the catalytic activitieswere enormously decreased under the presence of SO2 and H2O, respectively or simultaneously, compared withthose under the cases of the absence of SO2 and H2O. However, the presence of SO2 promoted the performance of thecatalytic filter above 320 oC with showing the NO conversion better than 99.8% for the NO inlet concentration of 500ppm and at the face velocity of 2 cm/s. In particular, the presence of water showed high NO conversion higher than 99%up to high temperature of 380 oC. This effect of water was explained by the reason that it retarded the ammonia oxidationwhich is the main step into the formation of N2O. The initial NO reduction activity of the catalytic filter maintainedfor the duration of 100 hours in the presence of SO2 and H2O. Therefore, it was concluded that the catalytic filter waspromisingly useful for the industrial NOx reduction catalyst in order to treat the particulate and NO simultaneously.

This study examine primary human resources, which should be obtained by employees in order to satisfy those who use sports centers, and also has an objective of collecting basic data for real life application and execution in the sports centers. The study is based on quantitative approach and aimed to regular customers, who registered and used sports centers more than 6 months so far(October of 2002) as a group and they were classified according to their resident areas(Gwangju, Mokpo), 50 individual on each area and 100 as a total. A survey document with depth was used as a study tool and the results were classified and arranged by researchers. The Study results obtained by executing the procedures above are as follows. Firstly, when seen in the front area, maintenance of neat, clean and comfortable environments seemed to satisfy customers generally and clear communication, prompt response and polite expression increased the satisfaction level of customers where customers were irritated by perfunctory reply, low voice and impatient manner linguistically. In terms of attitude, greeting with right pose and body standing still and remembering characteristics of each customer were the satisfactory factors, on the other hand, inconsistent, unfriendly and careless manner were the unsatisfactory factors. Secondly, in terms of language, polite, courteous, friendly language and honorific expressions between employees were critical factors and customers felt offended when employees communicated impolitely or had no answer for question or when employees communicated each other with no manner. In terms of attitude, customers appreciated when employees greeted them with smile, wore uniform with name tag, wore neat uniform and treated them with respect regardless of their outer appearances. However, customers did not appreciate when employees had bad manner, courteous looks and treated them differently according to their looks. Thirdly, in terms of instructors, customers preferred instructors, who used simple and precise languages with intensive instruction over instructors who used complicated and technical terms, overpowering and commanding language and who talked too fast or provided lengthy explanation. In terms of attitude, customers appreciated instructors who taught them with details and care where they were mostly irritated by the ones who showed them insincere attitude, explained without certain demonstrations, treated them as junior or ignored them according to their ability.

Objectives: This study was designed to examine the effect of Hominis Placenta Pharmacopuncture on the change in behavior, sleep-related hormones, inflammatory cytokines, anti-oxidants, weight, blood, and serum on rats given chronic physical stress. Methods: Wistar rats older than age 10 weeks were used in this experiment. They were divided into six groups. The normal group was not given stress. The control group was given only chronic physical stress and no treatment. The positive control group was given chronic physical stress and treated with zolpidem. Three Hominis Placenta Pharmacopuncture (HPP) groups were given chronic physical stress, then treated with different concentrations of HPP; HPP-0.5× (0.5 times diluted), HPP-1× (undiluted) and HPP-2× (2 times condensed). The changes of values of Nestlet Shredding results, weight, Melatonin, Gamma-aminobutylic Acid (GABA), Tumor Necrosis Factor Alpha (TNF-α), Interleukin-6 (IL-6), Superoxide dismutase (SOD), glutathione peroxidase (GPx), AST, ALT, BUN, Creatinine, and leukocytes were observed during the experiment. Results: The changes in chronic physical stress of the rat model were as follow. The Nestlet Shredding result increased in the control group compared to the normal group (p<0.05), and decreased in the HPP-1× and HPP-2× compared to the control group (p<0.05). The amount of weight gain showed increasing tendency in the HPP-2× compared to the control group since the second week. The GABA increased (p<0.05) and Melatonin also showed certain increasing tendency in the HPP-1× and HPP-2× compared to the control group. The TNF-α and IL-6 increased in the control group compared to the normal group (p<0.01), and decreased in all the HPPs compared to the control group (p<0.05). The SOD level decreased in the control group compared to the normal group (p<0.01), and increased in all the HPPs compared to the control group (p<0.05). GPx, AST, ALT, Bun, Creatinine and leukocytes showed no noticeable difference among all groups. Conclusions: Hominis Placenta Pharmacopuncture was effective in increasing weight, GABA, Melatonin, SOD, and decreasing Nestlet Shredding and inflammatory cytokines, suggesting that it consequently facilitates in relieving physical stress.

There has been a non-profit organization which has been developing Experiential Activity programs for about 50 years. These program can develop self-reliance, a sense of responsibility and leadership for members through direct and a variety of group activities and members can learn how to share group experience with other people, how to lead a group and how to contribute to the group as an individual. The worldwide trends are that experiential activity programs like Outward Bound are active and many of schools in various countries have adopted the program as their regular course. However, so far there have not been a program or institute to organize, facilitate and promote Experiential Activity in Korea even though the youth related social issues are growing bigger so people are beginning to realize the necessity of such a program and institute. In this paper, such necessity of Experiential Activity is examined and the analysis of environment and potential market is performed for Korean style Experiential Activity model development. Wth this initiative, the Korean style Experiential Activity school will be able to provide program attendees and its members with a positive attitude toward life as well as a variety of experiences and self-development opportunities like a leadership program.
