The purpose of this study was to evaluate the suitability of a high-strength polyester fabric as a material for air leisure sports, by comparing its physical properties with those of commercially available nylon fabric. In addition, the weatherability during the winter season outdoor exposure test was compared, for evaluation in an actual operating environment, and the degradation behavior after outdoor exposure was examined. The tensile strength, elongation, and tear strength of the polyester fabric having a ripstop structure were found to be sufficient to substitute nylon fabric, which has been used for air leisure sports. Furthermore, the weather resistance test by outdoor exposure indicated that the polyester has excellent weatherability, compared with that of nylon. Compared with that in outdoor weathering, the accelerated weathering of nylon and polyester fabrics leads to a more rapid decrease in the elongation and tensile strength. SEM, spectrophotometry, FT-IR, XRD, and TG analyses showed that the polyester was less degraded than the nylon fabric.

보험소비자의 권리 및 책임의식과 보험구매 의사결정 행동

장연주(Younju Jang),최현자(Hyuncha Choe),한지형(Jihyung Han) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.9

본 연구에서는 보험소비자의 권리의식과 책임의식의 수준이 어떠한지 살펴보고, 권리 및 책임의식 수준에 따라 소비자를 유형화하여 유형별 의사결정 행동에 어떠한 차이가 있는지를 실증적으로 분석하였다. 이를 위해 생명보험협회의 ‘생명보험업의 민원발생유형 분석 및 소비자보호 강화방안’의 총 1,225명 데이터 를 활용하여 확인적요인분석, 신뢰도분석, 대응표본 t-test, 교차분석 및 분산분석을 시행하였다. 연구결과 보험소비자의 책임의식은 권리의식과 비교했을 때 비교적 낮은 수준이었고, 권리의식에 상응하는 책임의식이 갖추어진 소비자집단이 더욱 합리적이고 주체적인 의사결정을 내리고 있음을 확인할 수 있었다. 이러한 결과를 바탕으로 보험소비자의 바람직하고 주체적인 의사결정을 위해서는 권리의식에 상응하는 책임의식을 강조하는 소비자교육이 필요함을 확인하였다. 본 연구는 소비자문제를 해결할 수 있는 보험소비자의 권리 및 책임의식의 제고를 위한 콘텐츠개발의 기초자료를 제공한다는 점에서 의의가 있다. 특히 금융소비자의 권리의식과 책임의식에 관한 연구가 다각도로 이루어지지 않은 상황에서, 권리의식만큼이나 책임의식이 중요하다는 것을 학술적으로 밝혔다는 점에서 더욱 의의가 있다고 할 수 있다. The purpose of this study is to analyze the level of consumers’ right and responsibilities consciousness, and to analyze the difference of decision - making behaviors according to type of consumers’ rights and responsibility consciousness level. The data collection subjects were those who had made the decision to purchase insurance directly within the last three years. A total of 1,225 data were used for the final analysis in this study. As a result, the consumers sense of responsibility was lower than that of the rights consciousness, and the consumer group with the responsibility consciousness corresponding to the right consciousness was making more rational and subjective decisions. Based on these results, it is confirmed that consumer education that emphasizes responsibility consciousness corresponding to right consciousness is necessary for desirable and subjective decision making of insurance consumers. This study is meaningful in that it provides basic data for contents development to raise the awareness of rights and responsibilities of insurance consumers who can solve consumer problems.

보험소비자의 의사결정과정에 관한 탐색적 연구: 근거이론적 접근

장연주 ( Younju Jang ),최현자 ( Hyuncha Choe ) 한국소비자학회 2013 소비자학연구 Vol.24 No.4

The objectives of this research are: 1. to comprehensively understand consumer’s decision-making experience from contextual perspective; 2. to identify different types of decision-making process that occur within different contexts; 3. to determine how those factors function. The ultimate objective of this research is to materialize the theoretical basis of decision-making process of the insurance consumers. To fulfill the above objectives, this study adopted the methodology of grounded theory of qualitative research. The following is the research outcome. First, the decision-making process adopted by the insurance consumers was to select and implement strategies that can help them overcome the obstacles in making purchasing decision under their respective circumstances. They were faced with challenges due to the special characteristics of insurance products and the level of difficulties largely depended on the market environment of insurance industry as well as the level of information shared. Under these circumstances, factors such as consumer confidence, level of involvement, amount of usable resources either deteriorated or alleviated the level of difficulties. Also, the strategies adopted by the consumers to deal with the difficulties were diverse. These experiences shared by the insurance consumers led to efforts to make optimal decisions and this created a relationship between insurance representative and consumers, post-purchase satisfaction or dissatisfaction, post-purchase behavior, and expectation for government support and overall improvement in the industry. Second, the coping strategies adopted by the insurance consumers fall under two categories. First is utilizing different channels to find information and make purchase, such as using consumer-direct information resources, face-to-face and non-face-to-face sales channels. Second is adopting strategies to lessen the cognitive burden by delaying the decision-making and deciding to spare less effort. What this implies is that strategies differ depending on the balance between desire to make the right decision and desire to minimize the cognitive burden. Third, common experience among the surveyed insurance consumers was the challenge of making the purchasing decision. To overcome this, they usually obtained and processed the necessary information. Fourth, the level of difficulties can either increase or decrease based on the characteristics of the insurance product as well as the consumer perception of insurance market environment. Fifth, intervening factors such as consumer confidence, level of involvement, and usable resources either deteriorate or lessen the difficulties, and determined the result of consumers’ decision-making process. This research has the following significance. First, the fragmentary research on consumers’ decision-making process can be applied to insurance consumers to provide theoretical basis which will enhance the systematic and comprehensive understanding of those consumers. Second, under the current circumstances in which no such research has been completed in regards to decision-making process of the insurance consumers, exploratory research can be utilized to shine a light on new finding which reflects special characteristics of insurance products.

장연주 ( Younju Jang ),최현자 ( Hyuncha Choe ) 한국소비자학회 2015 소비자학연구 Vol.26 No.5

The objectives of this research are: 1. to identify different types of decision-making process that occur within different contexts; 2. to determine how those factors function. To fulfill the above objectives, participants were categorized based on their decision-making strategies and revealed the difference in strategies and categorical characteristics through analysis of actual proof. The following is the research outcome. First, the type of insurance consumers was categorized into four different types depending on what strategy they adopt: non-face-to-face sales channels, face-to-face sales channels, face-to-face sales channels and consumer-direct information resources and the ones that use multi-channels. Depending on to which type they belong, the consumers showed different characteristics in decision-making as well as socio-demographic difference. Second, it was observed that strategies adopted by the consumers determined what sort of burden was eased. Third, the effect of specific strategy in easing the consumer burden varied widely depending on the type. Fourth, intervening factors such as consumer confidence, level of involvement, and usable resources either deteriorate or lessen the difficulties, and determined the result of consumers’ decision-making process. The effect of intervening factors varied widely depending on the type. This research has the following significance. Categorizing the consumers by what strategies they adopt when making decision can provide ground to create different approach that reflects both practical insights and policy perspectives.
