본 연구에서는 현재 전복 사고가 자주 발생하는 Model A와 Model B의 중형 세단 차량들의 사이드 도어들을 구조 해석으로 서로 비교한다. 구조해석 결과, 두 모델 모두 전복 사고나 충격 시 하중이 작용되는 부분에서 최대 변형이 일어났고 2개의 모델 중 Model A가 Model B와 비교하면 충격력을 더 견딜 수 있다. 또한 도어의 모서리 부분에서 최대 응력이 일어났고 Model B가 Model A보다 2.5 배 더 응력이 커진다. 충돌 사고가 일어날 시, 2개의 모델 중 그 최대 응력이 작은 Model A가 Model B와 비교하면 더 큰 충격력을 견딜 수 있다. Model B가 Model A보다 더 큰 변형량을 갖는 것으로 보아 측면 충돌 사고에서는 Model A보다 위험할 것으로 사료된다. 차종별 차량 옆문의 충돌해석을 적용함으로서 본 논문에서의 연구 결과는 미적인 설계를 적용할 수 있는 융합 연구자료로서 유리하다고 여겨진다.

미국 위스컨신주 도어 지역의 지하수내에서 납성분이 시기적, 장소적으로 불규칙하게 산출되었다. 본 연구에서, 지하수의 납성분의 오염도를 나타내주는 지시자들(검출빈도, 납성분의 평균, 최고 검출농도)과 지하수의 납 오염에 관계가 있을 가능성이 있는 7개의 독립변수들과의 상관계수가 계산되었다. 이 관계의 통계적 중요성은 t-test에 의하여 90%의 신뢰도에서 이루어졌으며, 이 지역에 산재하는 농약(lead-arsenate)의 처리장소가 지하수내 납성분의 요염 원인임을 통계학적으로 입증하였다. 납성분으 산출농도가 높았던 5개의 가정우물로부터 총 112개의 지하수시료가 채취분석되었다. 납성분은 $0.45{\;}\mu\textrm{m}$의 공극 크기를 지닌 여과지에 걸러진 미립자에서 검출되었으며, 여과액에서는 검출되지 않았다. 이러한 결과는 납성분이 이 지역의 지하수내에서 미립자이 상태로 존재함을 지시한다. 따라서, 이 지역에서 납성분의 불규칙한 산출은 미립자상의 납이 수평과 수직으로 발달된 파쇄대와 같은 유동경로를 따라 이동하면서 나타나는 현상으로 고려된다.

This study examines the comfort of outdoorwear by electrocardiogram (ECG) and electroencephalogram (EEG) analyses. An experiment that consisted of rest (30 min), exercise (30 min), and recovery (20 min) periods was administered in a climate chamber with 10 healthy male participants. Two kinds of outdoorwear made of 100% cotton fabrics ('Control') and specially engineered fabrics having the feature of quick sweat absorbency and high speed drying fabric ('Functional') are evaluated in the experiment. ECG and EEG signals were obtained during the rest and recovery periods for the two outdoorwear conditions. The ECG analysis identified a smaller decrement of high frequency (HF) power for the 'Functional' when compared with the 'Control' during the recovery period. Next, the EEG analysis showed that the relative band powers of slow $\alpha$ and mid $\alpha$ increased for the 'Functional' while they decreased for the 'Control' and that the ratio of $\alpha$ power to high $\beta$ power was higher for the 'Functional'. The evaluation results indicate that the participants could remain relaxed more with less stress while wearing the functional outdoorwear that demonstrated the positive effects on autonomic nervous system (ANS) activities. The present study is significant in regard that use of ECG and EEG for the assessment of wear comfort is the first in the field of clothing and textile.

This study analyzed the effects of consumption value of outdoor female consumers on relationship quality and long-term relationship orientation as well as differences in consumption value, relationship quality and long-term relationship orientation by demographic characteristics. A survey was conducted from May 15-22, 2016; subsequently, 336 responses were used in the analysis. Statistical analysis methods consisted of frequency analysis, factor analysis, reliability analysis, t-test, ANOVA, and regression analysis. The results indicate that the consumption value of outdoor female consumers was composed of functional value, emotional value, epistemic value, situational value, and social value. Relationship quality was composed of satisfaction, commitment, and trust. Consumption value (functional value, emotional value, epistemic value, situational value, and social value) of outdoor female consumers positively affected satisfaction. Emotional value, epistemic value and situational value positively affected commitment; in addition, functional value and emotional value positively affected trust. Satisfaction, commitment, and trust about outdoor brand also positively affected the long-term relationship orientation; in addition, consumption value positively affected long-term relationship orientation. There were significant differences in the consumption value and relationship quality by age and marital status. The study results provide useful information for the marketing strategies of outdoor brands that consider female consumers.

This research aimed to identify the characteristics of outdoor apparel market for new seniors. To achieve this goal, influence of new seniors' lifestyle and apparel purchase criteria of design preferences of outdoor apparel products were investigated. An online-survey was conducted targeting fifties who have bought outdoor apparel within one year. The collected data were carried out for factor analysis, independent sample T-test, and regression analysis by using SPSS 22.0. Results showed that new seniors' lifestyles were composed of appearance-orientation, well-being diet, well-being exercise, self-development, and challenge-orientation. Purchase criteria of outdoor apparels were factored out as practical, aesthetic, and social. Appearance -orientation and self-development affect aesthetic and social factors. Well-being diet influences all factors of purchase criteria. Challenge -orientation has effect only on social factor. Women favored round-and V-neckline more than men did as well as preferred half and 3/4 long for sleeve. Customers who value practical purchase criteria preferred half-sleeve, zipper, and button-closure designs. In contrast, customers who have aesthetic purchase criteria like round/V-neckline and cap sleeve. Social factor affected high neckline and vivid-tone color preference significantly. As outdoor design for new senior it is critical to introduce differentiation of outdoor brand with various designs combining functionalities of outdoor activities and style looking young and dandy, which is highlighted as trendy and casual, over current outdoor apparels' unified design.

The purposes of this study were to segment outdoor wear market based on consumer knowledge and consumer demand for function/design development, and to examine the differences of demographic characteristics and purchase behavior among the segmented markets. Data were collected using a questionnaire survey. Respondents were adults aged over 20 and who have experiences of purchasing outdoor wear. The survey was made up of the questions on consumer knowledge to outdoor wear, consumer demand for product development, purchase behavior, and demographic characteristics. Frequency analysis, descriptive analysis and chi-squared test were used to conduct the data analysis on 454 questionnaires. The results of this study were as follows. It showed that the consumer knowledge was a little high and the consumer demands for function/design development were high. Six segmented markets based on consumer knowledge and consumer demand for function development were significantly different in terms of gender, income, purchase frequency and total item holdings. Also, six segmented markets based on consumer knowledge and consumer demand for design development were significantly different in terms of age, income, purchase frequency, purchase objective, purchase place and total item holdings. Compared to the segmented markets based on the consumer demands for product development, the gender was the key of the marketing strategies for the segmented markets by the consumer demand for function development while the age was the one in the markets by the consumer demand for design development. After considering all the results, the characteristics of the segmented markets were made out and the marketing strategies were established.

This study analyzed the effects of consumers'sense of community regarding outdoor brands on behavioral commitment, purchasing satisfaction, and repurchasing intention and analyzed the effects of behavioral commitment and purchasing satisfaction on repurchasing intention. Additionally, this study analyzed the differences in sense of community, behavioral commitment, purchasing satisfaction, and repurchasing intention according to the types of outdoor consumers'consumption values. A survey was conducted from July 20th to 30th, 2015, and 527 responses were used for the analysis. The results of this study are as follows. First, consumers'sense of community regarding outdoor brands was classified into mutual influences, sufficiency necessity, emotional connectedness, and sense of belonging. Second, outdoor consumers'sense of community had positive impacts on behavioral commitment, purchasing satisfaction and repurchasing intention. Third, outdoor consumers'behavioral commitment and purchasing satisfaction had positive impacts on repurchasing intention. Fourth, there were differences in the outdoor consumers'sense of community, behavioral commitment, purchasing satisfaction, and repurchasing intention according to the types of consumption values. Therefore, outdoor brands can strengthen the relationship with customers considering values and behavior, suggesting the need for a strategy that promotes consumers'sense of community with sustainable management activities that save the environment and local community.
