In modern society, there is a growing perception that a memorial space is a space that forms the relationship between the living with the dead as a medium. The term has also been changed from a term referring to a burial site or cremation site to the term "chumo space" with the added meaning of a resting place for those who visit it. The memorial hall gradually extended the space of the living and the dead according to the flow of society. Past times are passed and by creating the present through memory, we can sustain them through extramarital affairs. It examines the transformation of the solemn memorial space, the center of the dead from the past, into an open memorial space centered on the living. Divide and analyze by the concept of decartes in classical physics and Einstein's time and space in modern physics, and present the direction of memorial space applied with each characteristic accordingly, suggesting a memorial space for people to feel closer. Through this study, we hope that the memorial space applied with the characteristics of space and time will be recognized as a place for reminiscing and remembrance of the past, reducing the psychological and emotional distance of people from the space that is perceived as a hate facility. 현대사회에서는 추모공간이 죽은 자를 매개체로 하는 산 자들 간의 관계를 형성하는 공간이라는 인식이 늘고 있다. 용어 또한 시체를 매장하거나 화장하는 장소를 지칭하는 말에서 그곳을 찾는 사람들의 휴식공간이라는 의미가 더 추가되어진 ‘추모공간’이라는 용어로 변화되어왔다. 추모공간은 사회의 흐름에 따라 점차적으로 산 자와 죽은 자의 공간이 조금씩 연장되며, 과거의 시간은 흘러가고 기억을 통해서 현재를 창조함으로써 추모를 통해 지속적으로 유지할 수 있다. 사회의 변화에 의해 과거의 죽은 자 중심인 엄숙한 추모공간이 산 자 중심의 개방적인 추모공간으로 변화한 것을 고찰하고 고전 물리학에서의 데카르트와 현대물리학에서의 아인슈타인 시공간 개념으로 나누어 분석하고, 그에 따른 각각의 특성을 적용한 추모공간의 방향성을 제시함으로써 사람들이 더욱 가깝게 느낄 수 있는 추모공간을 제안하고자 한다. 본 연구를 통하여 시공간의 특성을 적용한 추모공간이 혐오시설로 인식되고 있는 공간에서 사람들 심리적, 정서적인 거리감을 줄여주며 과거를 회상하고 추모하는 공간으로 인식되기를 기대한다.

IoT 환경의 단말 인증 시스템

강동연,전지수,한성화 한국정보통신학회 2023 한국정보통신학회논문지 Vol.27 No.1

IoT is being used in a lot of industry domain such as smart home, smart ocean, smart energy, and smart farm, as well as legacy information services. For a server, an IoT device using the same protocol is a trusted object. Therefore, a malicious attacker can use an unauthorized IoT device to access IoT-based information services and access unauthorized important information, and then modify or extract it to the outside. In this study, to improve these problems, we propose an IoT device authentication system used in IoT-based information service. The IoT device authentication system proposed in this study applies identifier-based authentication such as MAC address. If the IoT device authentication function proposed in this study is used, only the authenticated IoT device can access the server. Since this study applies a method of terminating the session of an unauthorized IoT device, additional research on the access deny method, which is a more secure authentication method, is needed. IoT는 전통적인 정보 서비스뿐만 아니라 다양한 분야에서 활용되고 있다. 특히 스마트 홈, 스마트 해양, 스마트 에너지나 스마트 팜 등 많은 융합 IT 분야에서 IoT 기술을 활용하고 있다. IoT 기반 정보 서비스의 서버에 대하여, 지정된 프로토콜을 사용하는 IoT 단말은 신뢰된 객체이다. 그래서 악의적 공격자는 인가되지 않은 IoT device를 사용하여 IoT 기반 정보 서비스 접근, 인가되지 않은 중요 정보에 접근 후 이를 변조하거나 외부에 유출할 수 있다. 본 연구에서는 이러한 문제점을 개선하기 위하여 IoT 기반 정보 서비스에서 사용하는 IoT 단말 인증 시스템을 제안한다. 본 연구에서 제안하는 IoT 단말 인증 시스템은 MAC address 등의 식별자 기반 인증을 적용한다. 본 연구에서 제안하는 IoT 단말 인증 기능을 사용하면, 인증된 IoT 단말만 서버에 접근할 수 있다. 본 연구는 비인가 IoT 단말의 세션을 종료하는 방식을 적용하므로, 보다 안전한 단말 인증 방식인 접근 차단에 대한 추가연구가 필요하다.

Purpose: The purpose of this study was to examine correlations among UPDRS, respiratory function, and senior fitness and to investigate the effects of restrictive respiratory function on these factors in Parkinson's disease patients. Methods: Subjects (n=25, Hoehn & Yahr (H&Y) stage: 2-3, $69.3{\pm}5.9$ yrs) from D Hospital Parkinson's Disease Center at Busan metropolitan area in the Republic of Korea volunteered for this study. They performed the pulmonary function test, UPDRS, and the senior fitness test. SPSS 18.0 was used for analysis of data, and the collected data were analyzed using Pearson's correlation coefficient (n=25). In addition, Independent t-test was used for determination of differences between two groups (between the normal pulmonary function group (n=10) and the restrictive pulmonary function group (n=10)). Results: Forced vital capacity (FVC (L)) showed significant negative correlation (r=-0.44, p<0.05) with H&Y stage in Parkinson's disease patients, and chair stand showed significant negative correlations (r=0.41, 0.43, 0.42, p<0.05) with FVC (L), FVC (%), and FEV1 (L). FVC (%) showed significant positive correlations (r=0.44, r=0.44, p<0.05) with right and left back scratch. In addition, the restrictive respiratory function group showed significantly lower FVC (%) (p<0.01) and was significantly slower (p<0.05) in the 8-foot up-and-go test than the normal respiratory function group. Conclusion: In conclusion, these results suggest that restrictive respiratory function in PD was related to H&Y stage. In addition, agility of PD patients was lower in the restrictive respiratory function group than in the normal function group.

Purpose: The purpose of this case study was to investigate three poor fibrinolytic responders with chronic ischemic stroke to acute exercise intensity and time. Methods: Three ischemic stroke patients (male) from the stroke center located at Busan metropolitan area in Republic of Korea volunteered at this study. They performed two single session exercises that were a VO2peak test and a single bout treadmill walking (70-75%HRpeak, 30 min, 50min). Fasting blood samples for determination of tissue Plasminogen Activator (tPA) and Plasminogen Activator Inhibitor-1 (PAI-1) were obtained before, immediately after, 30min after acute exercise. SPSS 12.0 was used for analyzing of data and computing mean and standard deviation, and change rate was conducted between times. Results: In fibrinolytic activity according to the intensity and time of acute exercise, tPA change increased steadily during the recovery stage after the VO2peak in the cases, but PAI-1 activity showed different patterns among the cases. In a single bout treadmill walking (70-75%HRpeak, 30 min, 50min), tPA change increased between 30min and 50min. Conclusion: In conclusion, these results suggest that the exercise prescription for poor fibrinolytic responder with three male chronic ischemic stroke patients without motor disability recommend at 70-75%HRpeak, over 30min.

강동연,손태윤,주예일,최응호,정병조,Kang, Dong-Yeon,Son, Tae-Yoon,Joo, Yea-Il,Choi, Eung-Ho,Jung, Byung-Jo 대한의용생체공학회 2010 의공학회지 Vol.31 No.2

Intense pulsed light(IPL) is a photo-therapeutic medical device using xenon lamps with optical characteristics of incoherence, defocusing, and polychromatic. IPL has been recognized as a representative medical therapeutic device with growth of domestic skin care market. However, there is no standard regulation manual and guideline to evaluate the safety and performance of IPL. International Electrotechnical Commission(IEC) is being statued "Technical Report IEC TR 60825-16" which is a guidelines for the safe use of intense light source equipment on humans and animals. In this study, a standard Korea Food & Drug Administration (KFDA) regulation for the safety and performance of IPL was suggested by developing minimal evaluation methods for optical parameters of IPL such as output energy density, pulse mode, spot size, wavelength and uniformity of output light. We expect that this study may be a step to statue a standard regulation manual and guideline for IPLs used in domestic.
