This study was performed to investigate the negative side effects of video display terminal (VDT) work on the human body and to provide data for preventing VDT syndrome. A questionnaire survey was made to 339 VDT workers at 22 offices in Taegu, Kyungpook and Kyungnam areas from July 1 to August 31, 1994, and 280 of them were finally used for statistical analysis. The VDT syndrome in the present study inclhded five factors, namely as eye-related symptom, psychological symptom, general body symptom, musculoskeletal symptom, and skin-related symptom, and the estimates of Crombach coefficients of the five factors were 0.954, 0.952, 0.953, 0.957, and 0.955, respectively, showing very high reliability. In view of socio-economical characteristics, the symptoms of female were higher than those of male in the order of musculoskeletal symptom, eye-related symptom, skin-related symptom and psychological symptom. The age group of 30 years or less was higher than the older groups in the order of musculoskeletal symptom, eye-related symptom, psychological symptom and skinrelated symptom. The group of lower education level showed higher skin-related symptom. The psychological symptom and skin-related symptom increased as the amount of smoking increased. Higher eye-related symptom was observed in the group without glasses. In the job-related variables, the group of working on programming and data input showed higher eye-related symptom and psychological symptom. The group of working on programming and graphic design showed higher musculoskeletal symptom and skin-related symptom. The skin-related symptom increased as the total time of VDT operation per day increased. The group of working 2-4 hours followed by 15 minutes rest was higher in musculoskeletal symptom and psychological symptom. Higher musculoskeletal symptom was observed from the group working on Friday and Sunday. The group of 1 year or less working showed higher in skin-related symptom. In relation with the VDT type, all symptoms except skin-related symptom were higher in the group using monochrome monitor. As showed above, the questionnaire could be a tool for evaluating VDT syndrome and prevention of the syndrome would be possible by a comprehensive consideration of factors including socio-economic characteristics, job-related variables and VDT type.

자동차 주요 생산국인 우리나라 보행자의 교통사고 사망률은 인구 10만 명 당 5.28명으로서 OECD 평균의 약 2.5배에 달한다. 보행자를 감지하고 운전자에게 경보를 보내주는 시스템이 개발되어 보행자 교통사고를 조금이라도 줄일 수 있다면, 그 자체만으로도 보행자 감지 시스템의 가치는 충분하기 때문에 PDS에 대한 관심이 높아지고 있다. 보행자 교통사고율은 야간에 더 높기 때문에, 야간 보행자 감지 시스템에 주요 자동차 회사들이 관심을 두고 있으나, 그들은 일반적으로 고가의 나이트비젼 또는 복합적 센서를 사용하는 장비를 채택하고 있다. 본 논문에서는 PDS에서 나이트비젼 대신에, 넓은 동적 범위를 갖는 가시 스펙트럼 대역 흑백 카메라 한 대만을 사용하는 야간 보행자 감지 기법을 제안한다. 서로 다른 환경에서 촬영된 야간 동영상들에 대해 실험한 결과, 제안 알고리듬이 에지가 어느 정도 정확하게 검출되는 상황이라면 정확한 보행자 검출 성능을 보였다.

The color gray in the cinema expresses the private or public memory and oblivion in the reminiscence scenes. The aesthetic function and meaning of gray that interacts with other elements in cinematic time and space are expanded in various ways. This study was analyzed the cases in which gray was used as the main visual style by limiting the scope to Korean films. Based on the traditional cultural symbolic meaning of gray, I analyzed how it was applied and transformed in films, and interpreted the cultural-social meaning by the interaction between gray and other elements. In film history starting from monochrome, gray has been used as a visual device suitable for realizing cinematic or imaginary reality. Gray is adopted when dreams or recollections are visualized as imaginary reality, and it is used when dreamy imaginations of daydreaming are demonstrated. Gray, which reproduces the dreamlike reality of imagination, is the concrete and realistic way of expression. First, in Korean films, gray is a flashback visual device that recalls the past, and is an intermediary visual form that materializes the imaginary. In films such as Ode to My Father (2014), DongJu (2015), A Resistance(2019) and The Battle : Roar to Victory (2019), the gray of the past is a visual device for cultural memory that builds the homogeneity and identity of the group. In the era of hyper-visibility, gray in black and white images is intended to be clearly remembered by unfamiliarity rather than blurry oblivion by familiarity. Second, in genre films with disaster materials such as Train To Busan (2016) and Ashfall (2019), the grays of rain, fog, clouds, shadows and smoke highlight other elements, and the gray color causes anxiety and fear. In war films such as TaeGukGi: Brotherhood Of War (2003) and The Front Line (2011), gray shows a more intense brutality than the primary color. In sports films such as 4th Place (2015), Take Off (2009) and Forever The Moment (2007), gray expresses uncertainty and immaturity. Third, gray visualizes the historical memory of A Petal (1996), the oblivion in Oh! My Gran (2020) and Poetry (2010), and the reality of daydreaming Gagman (1988) and Dream (1990). At the boundary between imagination and reality, gray is a visual form of dreams, memories and forgetfulness.
