The continuous development of in-vehicle information systems in recent years has dramatically enriched drivers’ driving experience while occupying their cognitive resources to varying degrees, causing driving distraction. Under this complex information system, managing the complexity and priority of information and further improvement in driving safety has become a key issue that needs to be urgently solved by the in-vehicle information system. The new interactive methods incorporating the augmented reality (AR) and head-up display (HUD) technologies into in-vehicle information systems are currently receiving widespread attention. This superimposes various onboard information into an actual driving scene, thereby meeting the needs of complex tasks and improving driving safety. Based on the qualitative research methods of surveys and telephone interviews, this study collects the information needs of the target user groups (i.e., beginners and skilled drivers) and constructs a three-mode information database to provide the basis for a customized AR-HUD interface design.

본 연구는 서울·경기지역 초등학생 학부모를 대상으로 식품첨가물에 대한 인식 및 정보요구도를 조사 및 분석하고, 이를 토대로 식품첨가물의 올바른 정보 제공을 위한 학부모 대상 교육용 스마트폰 앱을 개발하여 시범 적용 및 평가를 수행하였다. 식품첨가물에 대한 인식과 정보요 구도를 서울·경기지역 초등학생 학부모 358명을 대상으로 설문조사한 결과, 학부모들은 가공식품 구입 시 `안전성`(40.5%)에 가장 영향을 미치는 것으로 나타났으며, 식품을 구입할 때 제조일자나 유통기한 외에 제일 먼저 확인하는 사항은 `원산지`(35.4%)로 나타났다. 식품 구입 시식품표시사항을 이해하고 구매하는지에 대해서는 `보통이다`(45.1%)와 부정적 응답(15.7%)이 과반수 이상 나타났다. 식품안전에 가장 위협이 되는 요인으로 `식품첨가물`(42.7%)을 가장 많이 선택하였으며, 식품첨가물 중 `표백제 및 발색제` > `보존료` > `색소` 순으로 건강에 위험하다고 응답하였다. 가공식품 구매 시 식품첨가물이 적게 들 어간 것을 선택 하는지에 대해 긍정적 응답(63.1%)이 높은 반면, 가공식품의 식품첨가물 표시 내용 이해 여부에 대해 `보통이다`(49.2%)와 부정적 응답(21.0%)이 과반수 이상 나타났다. 식품첨가물에 관한 교육 및 홍보 필요성에 대해 88.0%가 긍정적 답변을 하였으며, 식품첨가물에 대해 가장 알고 싶은 정보는 `안전성`(74.3%)으로 나타났다. 설문 결과와 연구진의 브레인스토밍을 통해 1강, `식품첨가물이란?`, 2강, `식품첨가물 안전한가?`, 3강, `식품표시를 읽자`, 4강, `식약처의 안전 관리`, 5강 `애니메이션 즐겨보기`로 구성하여 `식품첨가물 바로 알기` 앱을 개발하였다. 개발된 교육용 앱을 서울·경기지역 초등학생 학부모 27명에게 시범 적용하여 교육 전과 교육 후를 비교한 결과, 식품첨가물의 위해성에 대해 `조금 해롭다`(40.74%)에서 `해롭지 않다`(48.15%)로, 식품첨가물에 대해 `잘 모른다`(44.44%)에서 `약간 알고 있다`(59.26%)로, 식품첨가물이 들어있는 가공식품을 안심하고 섭취해도 되는지에 대해 `잘 모른다`(44.44%)에서 `그렇다`(59.26%)로 식품첨가물의 인식이 개선된 것을 확인할 수 있었다. 본 연구를 통해 개발된 교육용 스마트폰 앱 `식품첨가물 바로알기`는 학부모들에게 식품첨가물에 대한 올바른 이해와 부정적 인식을 개선하는 것으로 나타났으며, 이를 활용함으로써 식품첨가물에 대해 효과적인 정보전달 매체로 기여할 수 있을 것으로 사료된다.

Meteorological factors and air pollutants are associated with respiratory diseases, and appropriate use of weather and air quality information is helpful in the management of patients with such diseases. This study was performed to investigate both the utilization of weather and air quality information by, and the needs of, patients with respiratory diseases. Questionnaires were administered to 112 patients with respiratory diseases, 60.7% of whom were female. The rates of bronchial asthma and chronic obstructive pulmonary disease among patients were 67.0% and 10.7%, respectively. The majority of subjects (90%) responded that prevention was important for respiratory disease management and indicated that they used weather and air quality information either every day or occasionally. However, respondents underestimated the importance of weather and air quality information for disease management and were unaware of some types of weather information. The subjects agreed that respiratory diseases were sensitive to weather and air quality. The most important weather-related factors were diurnal temperature range, minimum temperature, relative humidity, and wind, while those for air quality were particulate matter and Asian dust. Information was gleaned mainly from television programs in patients aged 60 years and older and from smartphone applications for those below 60 years of age. The subjects desired additional information on the management and prevention of respiratory diseases. This study identified problems regarding the utility of weather and air quality information currently available for patients with respiratory diseases, who indicated that they desired disease-related information, including information in the form of action plans, rather than simple health- and air quality-related information. This study highlights the necessity for notification services that can be used to easily obtain information, specifically regarding disease management.

Agricultural information was discussed for suggesting tasks and solutions of knowledge based information system. States of agricultural information systems in rural development administration were described and problems and tasks were summarized in knowledge needs survey of farmers who have to decide many alternatives for farming. Hard to access information are soil state, disease and insect pest. Important information in agriculture are water, soil fertility, soil physical property, and accessibility from main road. In conclusion, knowledge based agricultural information system can be developed based on surveyed needs.
