The purpose of this study is to examine the factors that influence the risk perception of reality on social media. Specifically, we analyzed how exposure to risk issues through media and bridging/bonding social capital influence social and personal risk perception. Here, we categorized risk issues into infectious diseases, sex crimes, and radioactive contamination. Findings are as follows. The effect that the type of media and social capital have on risk perception vary depending on the risk issues. Regarding issues of disease and radiation, bridging social capital had a positive effect on social risk perception whereas bonding social capital had a negative effect on personal risk perception. In the case of sex crimes, bonding social capital affected both social and personal risk perception negatively, and an interaction effect between exposures and social capital could be found. The significance of this study is that it considers both media variables from previous studies and social capital variables essential to social media studies and combines the two in order to study the factors that influence risk perception.

2007 년 3 월 3.5 세대인 HSDPA 의 전국 서비스가 시작되면서 HSDPA 휴대전화는 영상통화를 중심으로 한 다양한 기능으로 소비자를 유혹하고 있지만 설문조사에 의하면 HSDPA 에 대해 소비자들은 과반수 이상이 필요성을 못 느끼고 있고 3 세대에서 2 세대로의 '역(逆) 번호이동'도 꾸준히 늘고 있는 것으로 나타났다. 이는 소비자들이 HSDPA 휴대전화라는 신기술에 대해 기술 수용과 혁신 저항을 동시에 하고 있는 것으로 판단된다. 따라서 기술 수용과 혁신 저항의 관점에서 연구를 진행하였다. 연구결과는 유용성, 편이성, 혁신제품의 특징, 더 좋은 제품 기대가 태도에 영향을 미치는 것으로 나타났고 자기효능, 복잡성, 지각된 위험, 기존 제품에 태도는 태도에 영향을 미치지 않는 것으로 나타났다.

Gimpo International Airport is only available for alternate airport for code F aircraft and it is difficult to operate larger aircraft capable of transporting more passengers than B747-400. This study has conducted to review the compatibility based on risk assessment to introduce the B747-8 operation procedures, excluding the A380 for practical reasons. Risk factors for main gear deviation when driving on curved sections of the taxiway was identified. The risk was analyzed as "high" level. As a risk reduction measure, the proceduralization of specific taxiing method "judgemental oversteer" was reviewed, and the result of the risk re-evaluation was lowered to a "low" level. As a result, the B747-8 was analyzed to be compatible. Additionally, It is suggested that review of pavement strength, de/anti-icing facilities, and passenger boarding bridge is necessary for actual operations.

High-rise buildings construction project have various risk factors. Major risk factors are negative results such as time delay and increase of costs. Therefore, this study was analyzed risk factors in construction stages of high-rise buildings using by PROMETHEE technique. For this, this research were identified risk factors through experts Focus Group Interview(FGI). And, PROMETHEE was used to setup evaluation standard for analysis of high-rise building construction risks. Next, the standard of evaluation index calculation was composed by using the definition level in PDRI. Preference function and evaluation index were identified through questionnaires. Through these processes, this study has calculated the importance of high-rise building construction risks using by PROMETHEE technique. As a result, high degree risk factors were as following. These are 'Operation plan of material lifting', 'Outrigger & Belt Truss Construction', 'Foundation work plan of high-rise building' and 'Considering a Structure concept of high-rise building'.

This paper focuses to identify and analyze the influence of the perceived risk and innovation adoption of the new products in the bio-industry. After a comprehensive literature review, we identified factors, such as perceived risks, perceived benefits, trust, fear of the unknown, innate innovativeness, and domain-specific innovativeness. An empirical result points that perceived benefits and domain-specific innovativeness have positive effect to the consumer's purchase intention, while trust and fear of the unknown don't have significant effect.

우리나라는 지구온난화에 따른 기후변화에 의해 홍수피해가 점점 늘어나고 있는 실정이다. 이에 따라 홍수피해를 최소화 하는 주민대피체계를 제시하고 있지만 각각의 지자체의 특성을 반영하지 못하고 있다. 이재민 수용소의 인원이 부족하거나, 대피로 경로가 안전하지 못하여 2차 피해가 일어날 수 있는 가능성을 가지고 있는 곳들이 존재하고 있다. 이러한 상황에서 재해가 발생한다면 2차 피해가 발생할 가능성을 가지고 있기 때문에 이재민 수용소의 추가 지정과 대피로 경로를 새로 지정한다면, 재해 발생 시에 피해를 줄이고 보다 신속하고 안전한 대피가 이루어 질 것을 기대할 수 있다. 본 연구에서는 의령군이 현재 지정하고 있는 이재민 수용소 및 대피로를 평가하여 이재민 수용소를 재선정하였다. 의령군은 위험지역에 대해서 32개의 이재민 수용소를 지정하여 운영하고 있었으며, 그 규모는 7,165명을 수용할 수 있는 것으로 조사되었다. 하지만 이 중 봉수면과 의령읍은 이재민 수용시설의 규모가 대상지역의 대피 인원보다 작게 조사되어 이재민 수용소의 증원이 필요한 것으로 나타났으며, 가례천의 대피로는 하천을 wlsk가야 하는 경로로 지정되어 있어 2차 피해의 우려가 있는 것으로 나타났다. 이와 같이 수용인원이 부족한 이재민 수용소에 대해서는 증원을 통하여 문제를 해결하였고, 이재민 수용소의 위치는 피재자의 평균보행속도를 고려하여 15분 동안에 남녀가 이동할 수 있는 보행거리인 1,125m 이내에 위치하는 이재민 수용소를 채택하였다(유완, 도시의 재해대피소 적정 위치선정 2005). 이재민 수용소의 적절한 위치 선정을 통하여 지정한다면 재해발생시 피해를 최소화 할 수 있으며, 신속하고 안전한 대피를 할 수 있을 것으로 판단된다.

2011년 후쿠시마 원자력발전소 사고 이후, 발전원의 위험사고비용 및 환경피해비용에 대한 관심이 대두되고 있다. 전력은 생산과정 뿐만 아니라 발전소 건설, 발전소 운영, 송 배전을 통한 전력 공급, 폐기물처리 등의 각 과정에서 다양한 환경비용을 야기하고 있다. 따라서 발전원의 환경영향을 수용자적 입장에서의 평가할 필요가 있다. 본 연구에서는 컨조인트 분석법의 일종인 선택실험법을 적용하여 발전에 따른 환경영향 속성들에 대해 평가한 후, 발전원별로 상이한 속성 값에 속 성별 추정치를 반영하여 발전원별 환경비용을 수용자적 입장에서 추정하였다. 발전원부문이 환경에 미치는 영향에 대한 속성을 온실가스 배출, 건강피해, 지역피해, 온배수 배출로 선정하였고, 제시금액은 비교 대상 발전원들의 전력거래 단가 및 가구당 지출하는 월평균 전기요금수준을 기준으로하여 35,000원에서 75,000원까지의 총 다섯 가지 속성수준으로 구분하였다. 다항로짓모형을 적용하여 발전원별 각 환경영향에 대한 속성별 한계지불의사액 추정하고, 발전원간의 환경비용을 산정하였다. kWh 당 수력발전(0원/kWh) 대비 타 발전원의 추가 환경비용은 26원/kWh­832원/Wh로 환경적 영향 측면에서 국민수용성이 가장 높게 나타났다.

The purpose of this study is to analyze the acceptance about new seed of Chinese cabbage and to analyze the factors affecting continuous use. Research model was derived based on the Technology Acceptance Model(TAM), the analysis was performed using Partial Least Squares(PLS). The factors significantly affecting the use of new seed of Chinese cabbage are innovativeness and seed promotion in antecedent variables and perceived usefulness in parameter variables, which have strong positive relationship among them. Therefore, efforts such as development and diffusion of high quality seed and securing a market for Chinese cabbage of new seed are necessary for improving perceived usefulness. Since these efforts including seed promotion can enhance the farmers' acceptance of new seed and reduce the risk that farmers would face in introducing new seed, these can also be very helpful in enhancing the farmers' innovativeness.

Consumers' enhanced intention to adopt the Mydata service or their voluntary provision of personal information is a very essential element in the stable growth of the Mydata industry along with the creation of corporate values. The growing leakage of customer information according to the rising value of data can have negative impacts on the use of Mydata service and shrink quality custom service needs based on the personal information provided by financial consumers. This study set out to identify security risks that financial consumers could recognize and security factors that could supplement them and investigate the effects of these security factors on consumers' intention to adopt the Mydata service, thus providing useful implications for increasing the acceptance of financial consumers and finding a strategy to expand safe utilization. The findings raise a need to guarantee the stability and transparency of information provided by customers as information subjects, and they should be essential requirements for the Mydata service. The security factors applied to guarantee them should include convenience in terms of financial service.

The purpose of this study was to identify factors that affect the characteristics and intentions of the elderly to use digital wealth management services. The subjects of this study were 312 elderly people over 50 years old. Based on the Value-based Adoption Model(VAM), the research model added price value, social influence, and perceived risk as research variables. As a result of empirical analysis, it was found that usefulness, enjoyment, price value, and social influence all had a significant positive (+) effect on perceived value. It was found that technicality had a significant negative (-) effect. On the other hand, no significant effect relationship was tested on perceived risk. The perceived value had a significant positive (+) effect on the intention to use. This study was meaningful in the academic research that it applied a research model that reflected the characteristics of the elderly who were not treated as mainstream in the technology acceptance model for digital wealth management services. In addition, it provided practical implications for providers' marketing strategies and government/public institution policy establishment to increase the use of digital wealth management services for the elderly.
