of hazardous risk factors, risk estimation and determination steps by reflecting the trend of overseas risk assessment. METHODS : In deriving, estimating and determining risk factors, comparing the procedures presented by the ILO with the domestic guidline to find out the differences in procedural. and, According to the domestic manual, after setting the criteria for determining a deterministic perspective, analyze the risk assessment data of a specific domestic company and three overseas risk assessment research data to analyze the differences in methodology domestic and abroad. RESULTS : Within the country, there is a possibility that a deterministic view may be applied to all stages of procedure, and certain corporate data to the risk estimation and determination stage. In the case of overseas, the trend of applying deterministic perspectives to the risk determination stage was confirmed. CONCLUSIONS : Present the need for a standard model for improving deterministic methods in the other two stages, excluding risk determination in the domestic evaluation procedure.

This study aims to make extruded rice snack with high quality in texture and nutrition by adding mealworm. Addition of the mealworm has the merit to fill in high-quality protein and unsaturated fatty acids which are insufficient in rice. Thus, the physicochemical properties were investigated through the process of extrusion cooking. As the extrusion process varied, the die temperatures were set to 120oC and 130oC. Also, the moisture contents were adjusted to 30% and 35%. The specific length, the expansion ratio, and the water absorption index increased as the added content of mealworm became higher. On the contrary, the density, the breaking strength, the apparent elastic modulus, and the water solubility index decreased. As mealworm and moisture content increased, DPPH radical scavenging activity significantly increased but the rancidity decreased. As a result, the addition of mealworm to the extruded rice snack was effective in improving texture, nutrition, and antioxidation.

최근 모바일기기를 중심으로 멀티터치 기술을 적용한 제품들이 각광받고 있다. 게임 분야에서도 멀티터치 기술을 채택한 플랫폼을 위한 게임이 활발히 개발되고 있다. 멀티터치 인터페이스는 기존의 조작과는 다른 방식의 사용자 경 험을 제공한다. 본 논문에서는 멀티터치 인터페이스에 대해 알아보고, 멀티터치 기술을 적용한 게임의 구현을 통해 설 계 방향을 제안한다.

본 연구에서는 학교급에 따른 한국 학생의 인공지능(Artificial Intelligence, AI)에 대한 태도를 차이를 분석하였다. 이러한 연구를 위하여 총 6,324명의 학생을 대상으로 학교급에 따라 AI에 대한 태도를 측정할 수 있는 검사 도구를 적용하였다. 또한, 학교급, 성별, AI 직·간접 경험, AI 교육 경험, AI 관심, 프로그래밍 언어 경험, AI 활용 빈도에 따른 AI에 대한 태도의 차이를 분석하였다. 연구 결과, 학교급과 성별, AI의 직·간접적 경험, AI에 대한 관심, 프로그래밍 언어 경험은 AI에 대한 태도에 영향을 주는 것으로 나타났다. 특히, 학교급이 높으며, 성별이 남성이며, AI의 직, 간접적 경험이 있으며, AI에 대한 관심이 높으며, 블록과 텍스트 기반 프로그래밍 언어를 모두 경험한 학생일수록 AI에 대한 태도가 긍정적인 것으로 나타났다. 반면에 AI 교육 경험과 AI 활용 빈도는 AI에 대한 태도는 유의한 영향을 주지 못하였다. 본 연구 결과는 한국 학생의 AI에 대한 태도에 미치는 요인을 학교급에 따라 분석하였는데 의의가 있다.

This is a comparative study focused on the scenic landscape preferences derived from visitors's perceptions at the Dulle-gil and the uphill trail in Bukhansan National Park. Unlike previous landscape assessment methods, this study contains more direct and on-site analysis with methods of understanding the visitors’ perceptions by using ‘visitor employed photography(VEP)’ which requires each visitor to take preferable scenic landscape with one’s own smart phone camera. The scenic landscape types at two different trails were categorized and then the types favoring most of participants were verified. There are total number of 16 visual landscape types preferred by participants at both the Dulle-gil and the uphill trail in Bukhansan National Park. As in terms of consensus photography(CP) on the Dulle-gil was found to have more diverse elements including both natural and artificial elements compare to the uphill trail. Furthermore, the perceptually excited node(PEN) at the Dulle-gill were found to be more scattered evenly whereas PEN at the uphill trail were concentrated on the entrance and the top of the mountain. It is necessary to consider that the scenic landscape management at the Dulle-gil and the uphill trail require different approaches. Facilities were set based on careful consideration of distinctive geographical features and vegetation in the Dulle-gil. And the management need to be focus on the 'forested area' maintaining natural state in the uphill trail. Futhermore, the result of the CP and PEN in the trails would be helpful to proceed the next step of landscape perception study depending on characteristics of groups.
