저휘도 환경에서 태블릿 PC를 이용한 장시간 독서시 문자대비가 가독성과 피로감에 미치는 영향

This study examines the effect of luminance contrast ratio of character on readability and visual fatigue during an hour-long reading session while using a tablet PC in ambient environments having low luminance limited to 25 cd/㎡. Experiments were conducted with four patterns of the tablet’s luminance contrast ratio of characters, namely 1:2.5, 1:4.5, 1:6.5, and 1:8.5, in low ambient luminance of 9 cd/㎡ and 25 cd/㎡. The obtained results show that the characters can be easily read at the luminance contrast ratio of character of 1:8.5 under surface luminance of 25 cd/㎡. Visual fatigue was evaluated through a subjective survey of symptoms. Physical, psychological, and visual fatigue were observed at a surface luminance of 9 cd/㎡, whereas solely visual fatigue was felt at a surface luminance of 25 cd/㎡. By assessing the physical fatigue using the value, it has been found that smaller the luminance contrast ratio of character, greater is the CFF variation rate. Furthermore, readability is poor and visual fatigue can be observed when the surface luminance is lower than the ambient luminance. However, readability can be improved by increasing the luminance contrast ratio of character to a value of 1:8.5. Thus, in low luminance environments, luminance contrast ratio of characters can affect readability and fatigue. Consider providing the full form of “CFF” so that the acronym can be used unambiguously throughout the manuscript.

현대 사회의 급속한 인구 고령화로 인해 우리나라 인구의 사망 및 질병의 구조가 만성질환 위주로 변화하고 있다. 만성질환은 고혈압, 당뇨 등 지속적인 관리와 꾸준한 생활습관 개선이 필요한 질환으로, 보건소 중심의 만성질환관리사업을 추진하여 교육 위주의 서비스를 제공하였으나, 이는 일부 파악된 환자에 국한되어 서비스가 전체적으로 확산되지 못하였고 의료기관에서의 진료와 보건소의 교육이 연결되지 못하여 효과적인 만성질환자의 건강관리가 어려운 실정이다. 따라서 본 연구는 만성질환자의 지속적인 관리를 위하여 1차 의료기관의 서비스를 통해 지역사회 건강서비스와 연계된 수요자 중심의 자기주도형 만성질환 건강관리 서비스모델 개발을 목표로 하였다. 서비스디자인 더블다이아몬드 프로세스를 기반으로 지역사회 중심의 의료서비스 경험을 측정하기 위하여 데스크리서치 및 관찰‧인터뷰를 기반으로 한 현실적인 조사 방법을 통해 서비스 수요자‧공급자의 이용패턴 및 잠재적 니즈를 파악하고, 의료서비스디자인을 위한 서비스의 맥락(Contextual)을 분석하여 만성질환 건강관리 서비스 모델을 개발하였다. 이는 지역사회와 연계된 일차의료 중심의 만성질환 건강관리 서비스모델로, 동네 의원과 연결하는 건강센터를 구축하여 교육과 진료를 연계하여 하나의 확장된 서비스를 제공하고, 지속적으로 만성질환자의 꾸준한 관리를 기대할 수 있다. Due to the rapid population aging of modern society, the structure of death and disease in Korea is changing to chronic diseases. Chronic disease is a disease that requires continuous management such as hypertension and diabetes and improvement of lifestyle habits. It has provided education-oriented services by promoting the chronic disease management project centered on public health center. However, this is limited to a limited number of patients, And the health care of patients with chronic diseases is difficult because of the lack of connection between the medical care at the medical institution and the education at the health center. Therefore, this study aimed to develop consumer - centered self - directed chronic disease health care service model linked with community health service through the service of a general practitioner for continuous management of chronic disease patients. This study is to identify the usage pattern and potential needs of service consumers and suppliers to measure community-based health care service experience, by desk research, realistic research methods based on observation and interview, based on the Service Design Double Diamond process. And a chronic health care service model was developed by analyzing the context for service design. This is a primary health care centered healthcare service model linked to the local community. It will provide an expanded service by linking education and medical care, through a health center that connects with local clinic and constantly managing chronic patients.

본 연구는 골목 주거지의 쓰레기 무단 투기지역의 발생을 방지하고 주민들의 쓰레기 배출과정의 편의 및 청결한 주거환경을 제공하기 위하여 서비스디자인을 통한 거점수거대를 제안하는 것을 목표로 하였다. 골목 주거지의 환경 조사를 위해 단독주택, 다세대 주택이 밀집되어 있는 광진구를 대상으로 하여 현장조사를 진행하였고, 국내외 거점수거체계 및 사례 조사를 위한 문헌조사를 시행하였다. 이를 기반으로 서비스디자인의 방법론을 활용하여 주민들의 쓰레기 배출 행태를 파악하고 무단투기에 대한 행동 및 심리분석을 통해 원인을 파악하여 골목 주거환경에 적합한 거점수거대를 통해 사람들의 행동개선을 유도하도록 하였다. 쓰레기를 배출하는 과정에서 발생할수 있는 다양한 터치포인트를 통해 사용자의 편익과 쓰레기 처리의 효율성을 향상시키도록 하였고, 이를 통해 주민들의 생활에 긍정적인 영향을 미칠수 있도록 거점수거대를 활용한 서비스체계를 구축하였다. This study is to find problems about trash collecting system which is occurred between village streets. Since the rapid growth of industrial, the problems of the dropping of trash which is illegal is endemic in recent city. So, we studied to solve the problems from a viewpoint of public service design, suggested the system to throw in a spot to use the litter bin to prevent throwing away trashes illegality, to provide convenience when people separate and send out the recyclable waste and clean living environment. We performed field research in Gwangjin-gu, formed residential area of detached house and multiplex housing, to research living environment between city streets and literature research about internal and external case study about the system to throw in a spot to use the litter bin. Based on the research which was found in service design method, we understood people’s behavior to send out one``s garbages and the cause of behavior to throw away trashes illegality and suggested a design prototyped litter bin. We expected town people to solve the problems of trashes and to improve living public environment between city streets.

Recently, new building and remodeling of the library is going on the increase. The quality of air in libraries has been deteriorated due to frequent uses of chemical substances for construction material and furniture and poor vantilation. It is really important to keep fresh air quality in the children's library, because it is fully developed children's strong immune systems. There are a few studies about the air quality of libraries for adults, which are not mention children's library. The purpose of this study is to analyze the correlations between the indoor air quality and the construction conditions of the children's library. The contents include measured density of pollutants of CO, CO₂, HCHO, TVOC according to constructive conditions like environmental features, architectural materials for interior design and furnituring, and analyzed correlations between them. The subjects of the study are 7 public children's libraries in Incheon.
