Urban parks present keys to understand the background histories of urban planning formed in modern period. This paper is for discussing the urbanization and transition of park planning in Seoul: 京城, especially focusing on the small sized parks. City parks had already drawn attentions by Kyoungseong citizens from the beginning of 1920s, mainly indicated with rest or recreation functions. In small sized parks so called neighborhood playgrounds, functions for children’s health and education had been added on it. It was in 1930 that the practical ideas of urban park planning were suggested through ‘Kyoungseong City Planning’, prepared based on the investigation report of 7 pre-existing parks in Kyoungseong prefecture such as Namsan Park in 1927. Proposals in Kyongseong City Park Planning in 1930 laid a base to found later park planning, in the respect that it tried to place park sites applied from the results of calculating the open space areas with the whole planning areas and populations, even though it is hard to be considered the plan had covered comprehensive ways of functions and uses properly. Park planning got newly arranged a turning point with the promulgation of Kyoungseong Street Planning in 1936. Final plan was announced in March, 1940 completed with Street Planning and Land Readjustment Project promoted by Kyoungseong prefecture. It would be firstly cited as the most apparent differences compared to 1930’s park planning that numbers of isolated neighborhood playgrounds-small sized parks got created by the Land Readjustment Project. The number of total parks became increased to over 3 times as before from it and the way of classifying park types simple to follow the sizes not much to considerate the functions. Types of 140 parks including 38 areas prepared for parks in 1930 were rearranged as three types of grand parks, neighborhood parks and neighborhood playgrounds: large, medium and small sized. Neighborhood playgrounds in Seoul actualized just before Korea was liberated from Japanese governor, which had their main functions shifted from ‘education for children’ to ‘urban sanitation’. When they became finally showed their details through Kyoungseong Street Plan, the functions of ‘evacuation or air defense’ were put priorities on the same as other park types. The ideas of ‘vacant sites’ for emergency continued its transition to ‘public sites’ after the liberation and the Korean War. However, prepared open spaces were substituted for housings or education facilities according with their first necessities after the war. The park sites that had left their roles for civil affairs have transfigured to recreational facilities for residents, and have restored to civil parks occasionally.

본 연구에서는 개인 맞춤형 감성인식이 가능한 실시간 개인화 프로세스를 개발하였다. 설계된 개인화 프로세스는 실시간 생체신호 중립밴드 알고리즘과 사용자의 주관적인 감성응답을 실시간으로 입력받아 개인 감성 룰 베이스를 업데이트하는 과정을 포함한다. 실시간 감성인식을 위해 PPG(Photoplethysmography), GSR(Galvanic skin reflex), SKT(Skin Temperature)를 자율신경계 신호를 측정하고 사용하였다. 개인화 프로세스를 적용한 감성인식과 적용하지 않은 감성인식의 일치도 평가는 대학생 10명(남 5명, 여 5명, 22.1세± 2.2세)의 피실험자를 대상으로 실시하였다. 45장의 이미지를 무작위로 제시하였으며, 5회 반복 측정하였다. 개인화 프로세스를 적용시켰을 때 약 71.67%의 일치도를 보였으며, 적용시키지 않았을 때보다 약 5배 이상 높은 일치도의 차이를 보였다. 본 연구에서는 개인화 프로세스가 실시간 개인 맞춤 감성인식에 매우 유용함을 보였다. 추후 개인화프로세스는 다양한 감성 애플리케이션이나 서비스에서 감성인식 만족도를 높일 수 있을 것으로 판단된다. We designed a novel individualization process for improving personal emotion recognitions in real time. The designed individualization process was performed by a neutralization algorithm of physiological signals, a subjective emotion reflection of a user updated by personal emotion rules in real time. The physiological signals such as PPG(Photoplethysmography), GSR(Galvanic skin reflex), and SKT(Skin temperature) were measured and analyzed to estimate an emotion states of users. Regulating the emotion status using by emotion rules was performed by reflecting subjective evaluations. The agreement of emotion recognition between of individualization and non-individualization method was estimated by 10 undergraduates (5 females, mean age: 22.1 ± 2.2) of Sangmyung University. During the emotion recognition test, 45 images were randomly presented to each participant five times. In results, the proposed individualization process showed the agreement of 71.67 % which was five times higher than when the process was not applied. Therefore, in this study, we demonstrated that the individualization process was significantly useful for customizing emotion recognitions of personal users in real time. The individualization process will be able to improve satisfactions in various emotion related applications and services in the nearer future.

곽경덕,안상민,백승일,정찬종,노재수,Kwak, Kyoung-Duck,Ahn, Sang-Min,Baek, Seung-Il,Jung, Chan-Jong,Roh, Jae-Su 대한관절경학회 2006 대한관절경학회지 Vol.10 No.2

목적: 관절경적 후내측 도달법을 이용한 밸브기전의 교정을 통한 슬와 낭종의 절삭 절제술의 임상적 결과와 그 유용성을 보고 하고자 한다. 대상 및 방법: 2004년 4월부터 2005년 6월까지 변형된 관절경적 방법으로 슬와 낭종을 치료하였던 15례를 대상으로 하였다. 평균추시 기간은 15개월(범위: $12{\sim}28$) 이었다. Rauschning과 Lindgren의 평가 기준을 근거로 예후를 판정하였으며, 수술에 소요된 시간과, 슬관절의 통증이 없어지고 완전한 운동범위를 얻는데 걸린 기간을 측정하였다. 수술 후 12개월에 초음파를 시행하여 재발 여부를 관찰하였다. 결과: 기능평가는 Rauschning 과 Lindgren의 기준으로 최종 추시시 전례에서 Grade 0 또는 Grade 1 이었다. 수술 시간은 평균 45분(범위 $35{\sim}70$) 이었다. 전례에서 수술 후 5일 이내에 통증 없는 슬관절 운동범위의 완전한 회복을 얻을 수 있었으며, 1년 이상의 최종 추시에서도 운동범위는 모두 정상이었다. 재발한 예는 없었고, 통증과 보행 장애도 없었다. 결론: 후내측 도달법을 이용한 관절경술은 낭 주름의 밸브기전을 쉽게 교정할 수 있고, 슬와 낭종의 절삭술을 효과적으로 시행할 수 있는 대치방법으로 사료된다. Purpose: We evaluated the effectiveness of arthroscopic shaving cystectomy by using posteromedial portal for popliteal cyst with the correction of valvular mechanism. Materials and Methods: We had treated 15 cases of popliteal cyst with arthroscopic shaving cystectomy by using posteromedial portal from April 2004 to June 2005. The mean duration of follow up was 15 months (range: $12{\sim}28$). Functional results were based on the Rauschning and Lindgren criteria. We estimated operative time, time for regaining pain-free full range of motion and checked sonography for recurrence of the cyst at 12 months after the surgery. Results: The functional results by Rauschning and Lindgren criteria were rated Grade 0 or Grade 1 in all cases at last follow up. The average operation time was 45 minutes (range: $35{\sim}70$). All cases regained pain-free full range of motion within five days after surgery and range of motion was also normal at last follow up. There were no recurrence and no walking disturbance in all cases. Conclusion: Arthroscopic shaving cystectomy by using posteromedial portal is one of the effective alternative method of the treatment for popliteal cyst and it is also useful to correct the valvular mechanism.

3D TV 시청으로 유발된 시각피로가 자율신경계 기능에 미치는 영향

박상인 ( Sang In Park ),황민철 ( Min Cheol Whang ),김종화 ( Jong Wha Kim ),문성철 ( Sung Chul Mun ),안상민 ( Sang Min Ahn ) 한국감성과학회 2011 감성과학 Vol.14 No.4

최근 3D TV 보급과 확산에 따른 시각 피로문제가 대두되면서 시각 기능과 인지적 관점에서의 연구가 활발하다. 그러나 3D 시각피로가 자율신경계 기능에 미치는 영향에 대한 연구는 미비하다. 따라서 본 연구에서는 3D TV 시청으로 유발되는 3D 시각피로가 자율신경계 기능에 미치는 영향과 이 영향이 교감 및 부교감 신경계와 심혈관계 반응에 미치는 영향을 확인하고자 한다. 피험자는 20 대 남녀 대학생 15 명(남 6 명, 여 9 명, 평균나이 22.53 세 ± 2.55 세)을 대상으로 하였다. 피험자는 편안한 의자에 앉아 3D TV를 1시간 시청하였다. 3D TV 시청 전과 후의 1분간 맥파(PPG, Photo-PlethysmoGram)를 측정하였고 주관설문을 실시하였다. 측정된 신호에서 SDNN (standard deviation of RR intervals), RMS-SD(root mean square successive difference), HF/LF ratio, Ln(LF), Ln(HF)를 추출하여 교감 및 부교감 신경계, 그리고 심혈관계 반응을 확인 하였다. 연구 결과 HF/LF ratio, Ln(LF), Ln(HF)는 시청 후에 유의하게 감소하였고, SDNN, RMS-SD는 통계적 유의차를 확인할 수 없었다. 이 결과는 3D 시각피로가 자율신경계 기능에 영향을 미치고 이로 인해 교감신경계가 항진되는 반응이 나타나며, 심박 변화율이 감소하는 결과를 초래할 가능성을 확인 하였다. As technology in 3D industry has rapidly advanced, a lot of studies primarily focusing on visual function and cognition have become vigorous. However, studies on effect of 3D visual fatigue on autonomic nervous system have not less been conducted. Thus, this study was to identify and determine the effect that might have a negative influence on sympathetic nervous system, parasympathetic nervous system, and cardiovascular system. Fifteen undergraduates (female: 9, mean age: 22.53±2.55) participated and were sat on a comfortable chair, viewing a 3D content during about 1 hour. Cardiac responses like SDNN(standard deviation of RR intervals), RMS-SD(root mean squared successive difference), and HF/LF ratios extracted from the measured PPG(Photo-PlethysmoGram) before viewing 3D were compared to those after viewing 3D. The results showed that after subjects watched the 3D, responses in sympathetic nervous system and parasympathetic nervous system were activated and deactivated, respectively relative to those before watching the 3D. The results showed that HF/LF ratio, Ln(LF), and Ln(HF) after viewing 3D were significantly reduced relative to those before viewing 3D. No significant effects were observed in SDNN and RMS-SD. Results obtained in this study showed that visual fatigue induced by watching 3D adversely influenced autonomic nervous system, and thereby reduced heart rate variability causing sympathetic nervous acceleration.

기존의 졸음 평가 방법은 운전자 센서를 착용해야하는 부담감이나 운전 환경에 따른 제약이 존재함으로 새로운 졸음 평가 방법이 필요한 실정이다. 따라서 본 연구는 진동이미지 기술을 사용하여 EEG 변수와의 상관 분석을 통해 새로운 측정 방법에 가능성을 확인하고자 한다. 본 연구는 6명의 피험자를 대상으로 졸음을 유발하여 EEG 신호와 영상 데이터를 측정하였다. 측정된 EEG 데이터는 스펙트럼 분석을 통해 알파(Alpa), 베타(Beta), 세타(Theta), 델타(Delta)의 변수를 추출하였고 영상 데이터는 진동이미지기술을 통해 미동의 진동과 주파수를 의미하는 9개의 변수를 추출하였다. 추출된 EEG와 진동이미지 데이터의 각 변수는 상관 분석을 통해 비교하였다. 분석 결과 EEG와 영상 변수 간의 높은 상관관계를 나타내는 변수가 확인 되었다. 본 연구의 상관 분석 결과를 통해 추출된 진동이미지의 유효 변수는 기존의 졸음 평가 방법의 한계점을 보완 할 수 있는 새로운 졸음 평가 방법으로 활용 할 수 있을 것으로 예상된다. Previous Drowsiness evaluation methods used driver-dependant sensor, where it burdened dirvers to wear sensors and also distracted or limited drivers to drive freely. Due to this limitation and driver-unfriendly method, new drowsiness evaluation method was required. Therefore, this research was evaluating new method by using vibration image technology with EEG parameters and correlations. Six subjects were forcefully induced with drowsiness, and EEG signals and image data of each subject was measured by using new method. Measured EEG signal was anaylsed by FFT (Fast Fourier Transform) analysis to extract Alpha, Beta, Theta, and Delta parameters. Also, measured image data was extracted by using "vibration image technology" to achieve nine parameters such as A1, and etc. Obtained parameters were compared using correlation analysis. Result of this comparison showed that there was significant relationship between measured parameters and drowsiness. Conclusively, this new method will improve and compensate the limitation of existing method of measuring drowsiness.
