실시간 Social Distance 추적에 의한 감성 상호작용 인식 기술 개발
이현우,우진철,조아영,조영호,황민철,Lee, Hyunwoo,Woo, Jincheol,Cho, Ayoung,Jo, Youngho,Whang, Mincheol 한국감성과학회 2017 감성과학 Vol.20 No.3
This study developed a method which recognizes emotional interactions from the social distance by a beacon wearable device. The recognized interaction was evaluated by comparing with the cardiovascular synchrony from photoplethysmogram (PPG). The interaction was recognized when social distance was maintained for a certain period of time. The cardiovascular synchrony was estimated by correlation anaysis between beat per minute (BPM) from PPG. The maintenance time was determined by Mann-Whitney U test between the cardiovascular synchrony of interaction and non-interaction groups. Fifteen groups (2 persons per a group) participated in the experiment and they were asked to wear the beacon and PPG wearable devices in daily life. Experimental results showed that the interaction groups had more higher cardiovascular synchrony than non-interaction groups and the significant interaction time was determined to be 11 seconds (p=.045). Consequently, the real-time measurement and evaluation of the social network in real space was expected to be improved.

We treat problems of estimating reliability R(t) = P[Y(t) > X(t)] in the time dependent strength-stress model in which a unit of stress X(t) is subjected to environmental strength Y(t) at time t. In this paper we introduce a special model of R(t) with fixed strength and unaccumulated stress case, and propose a Mann-Whitney-Wilcoxon type estimator of R(t).

All across our nation, people live, work, and learn in indoor environments and especially, many people spend more time than ever before inside of cars. Recent years have been increasing attention focused on the air contamination inside auto-cabin. The sources of air contamination inside auto-cabin are roughly divided into internal sources(ex. chemical compounds from interior material) and external sources(ex. tail-pipe emission etc.). The Purpose of this research is to examine the status of worldwide auto-cabin air quality study, and to give the information when research is intended to develop methods to mitigate indoor air problem from auto-cabin.

PC(polycarbonate)/PBT(polybutyleneterephthalate) mixture is usually used for housing-reflector material of automotive fog lamp. This material has high HDT(Head Deflection Temperature) and is capable of being aluminum metalized for high reflectivity. However, PC/PBT mixture is more expensive than PP(polypropylene) which is used for automotive head lamp housing. Although PP is cheaper than PC/PBT mixture, PP is not used for light reflector because of its non-polarity. Polarity of material is essential to be aluminum metalized. In this study, PET based new material for housing-reflector material of fog lamp housing, which has polarity and high HDT, is developed to reduce its cost as well as improve its quality..

광 버스트 스위칭(OBS) 기술은 광 회선 스위칭에서 발생하는 자원의 비효율적인 사용을 개선시키며, 광 패킷 스위칭에서 해결해야 할 과제인 광 버퍼링의 요구사항을 최소화한다. GSMP는 제어기와 레이블 스위치 사이에서 연결, 구성, 성능, 장애관리 및 동기화 기능을 제공하는 개방형 인터페이스이다. 개방형 인터페이스는 광 전달망과 제어평면의 기술을 독립적으로 진화되게 하며 스위치의 구현을 단순화시키지만, GSMP 프로토콜의 실행 오버헤드로 인하여 연결설정을 증가시키는 단점이 있다. 본 논문에서는 OBS의 제어를 위한 GSMP 개방형 인터페이스의 사용 방안과 연결설정의 지연을 개선시키기 위한 병렬형 연결설정 메커니즘을 제안한다. OBS 신호 프로토콜과 GSMP 인터페이스의 구현을 통하여 병렬형 제어 메커니즘의 실현성을 확인하며, 기존 스위치-대-스위치 제어와 GSMP 기반 병렬형 연결제어의 연결설정 지연을 측정한다.
