Fashion stress is a pertinent aspect of modern consumer culture that has been underexplored in academic research. This study developed a conceptual framework of fashion stress and a multidimensional scale to measure consumers' fashion stress. The qualitative study included literature reviews on consumption stress, shopping stress, and consumer behavior, as well as focus group interviews to gain insight into various dimensions of fashion stress. NVivo 12.0 was used to analyze the qualitative data and identify core categories following the grounded theory methodology. The quantitative study involved a preliminary and a primary surveys to verify the validity and reliability of the fashion stress scale. A total of 220 questionnaires were used for data analysis. The results show that fashion stress consists of eight factors: care, shopping, fit, brand, financial, closet, style, and disposal. Choice difficulty plays a significant role in all factors of fashion stress. Moreover, shopping stress had a negative impact on impulse buying, while other factors such as fit, brand, closet, and disposal stress had a positive impact on impulse buying. Thus, fashion stress is a potential antecedent of impulsive consumer behavior. The results also confirm the validity and reliability of the scale. The fashion stress scale developed in this study offers researchers a valuable tool for assessing and understanding consumer experiences.

The goals of the paper are to understand the impact damage behavior and identify the effect of surface protective materials on impact resistance in filament wound composite pressure vessels. For these, a series of low velocity impact tests was performed on specimens cutting from the full scale pressure vessel by the instrumented impact testing machine. The specimens are classified into two types, which are with and without surface protective material. The visualization for impact damage by two different impactors is made by metallurgical microscope. Based on the impact force history and damage, the impact resistance parameters were employed,rod its validity in identifying the damage resistance of filament wound composite pressure vessel was reviewed. As the results, the impact resistance of the filament wound composites and its dependency on the surface protective material were evaluated quantitatively

오늘날 작업능률 및 운용효율의 향상을 위해 장비의 대형화 추세가 진행되고 있으나 이와 더불어 사고 발생 시에는 많은 인명 피해와 함께 크나큰 경제적인 손실을 초래하게 되어 대형장비의 안전성 문제에 대하여 많은 연구가 진행되고 있다. 대형구조물의 안전성 감시를 위해 외부의 부하에 따른 구조물의 변형은 스트레인게이지로, 순간적인 충격에 의한 진동은 가속도 센서를 이용한다. 본 연구에서는 고분자 압전 필름센서인 PVDF(PolyVinyliDene Fluoride)를 이용하여 구조물의 변형에 대한 측정뿐만 아니라 충격에 대해서도 민감하게 반응하여 하나의 센서로 부하와 충격을 모두 검출하여 산업적 효율성과 실효성 향상을 도모하였다. 개발된 센서는 스트레인 게이지의 출력값에 대해 14% 이내의 오차를 나타내고 가속도 센서와는 충격에 대해 동일한 패턴의 충격신호를 나타내었다.

본 연구는 뇌졸중 환자에게 지역사회 보행 훈련과 트레드밀 보행 훈련이 보행 능력과 뇌졸중 영향 척도에 어떠한 영향을 미치는지 알아보기 위하여 실시하였다. 본 연구에는 총 22명의 뇌졸중 환자가 참여하였으며, 대상자들은 무작위 추출법으로 지역사회 보행 훈련군 11명과 트레드밀 보행 훈련군 11명으로 각각 배정되었다. 모든 대상자들은 전통적 물리치료를 6주 동안 주 5회, 하루 30분씩 시행하였으며, 지역사회 보행 훈련과 트레드밀 보행 훈련을 하루에 30분씩 각각 추가적으로 실시하였다. 연구 결과 지역사회 보행 훈련군이 트레드밀 보행 훈련군에 비해 보행 속도와 분속수, 뇌졸중 영향 척도에서 유의한 차이를 보였다(p<.05). 이것은 지역사회 보행 훈련이 트레드밀 보행 훈련에 비해 뇌졸중 환자의 보행 능력과 뇌졸중 영향 척도에 유익한 영향을 준 것이라고 할 수 있다. 따라서 지역사회 보행 훈련은 뇌졸중 환자에게 실행 가능하며 적합한 훈련이 될 수 있을 것이라고 생각된다.

이 연구의 목적은 Stroke Impact Scale 3.0(SIS 3.0)의 신뢰도와 타당도를 조사하는 것이었다. 연구에서 SIS 3.0은 125명의 뇌졸중 환자를 대상으로 측정하였다(평균 = 62.7, 표준 편차 = 9.43). SIS 3.0 하위 영역들 간에 상관 분석을 통해 구성타당도를 확인하였고, MBI(Modified Barthel Index)와 K-MMSE(Mini-Mental State Examination-Korean)간의 상관을 분석하여 수렴타당도를 조사하였다. 각 항목의 특성은 고전적 문항 이론을 바탕으로 내적 합치도와 문항 변별도를 분석하였다. 이 연구를 통해 SIS 3.0의 구성타당도와 수렴타당도가 확인되었다. 감정 영역에 포함된 i 항목은 문항 변별도가 낮았지만 이 항목을 제외하고는 모두 변별도가 높았다. 하위 영역의 문항내적합치도는 0.858~0.941로 나타났다. 이 연구는 지역사회에 거주하는 뇌졸중 환자를 대상으로 임상 현장에서 SIS 3.0 사용을 위한 신뢰도와 타당도를 확인하였다는데 그 의의가 있다.

This paper aims to evaluate the structural dynamic responses and damage/failure of the nuclear fuel reprocessing plant under the free drop impact of spent fuel cask (SFC) and fuel assembly (FA) during the on-site transportation. At the present Part I of this paper, the large-scale SFC model free drop test and the corresponding numerical simulations are performed. Firstly, a composite target which is composed of the protective structure, i.e., a thin RC plate (representing the inverted U-shaped slab in the loading shaft) and/or an autoclaved aerated concrete (AAC) blocks sacrificial layer, as well as a thick RC plate (representing the bottom slab in the loading shaft) is designed and fabricated. Then, based on the large dropping tower, the free drop test of large-scale SFC model with the mass of 3 t is carried out from the height of 7 m-11 m. It indicates that the bottom slab in the loading shaft could not resist the free drop impact of SFC. The composite protective structure can effectively reduce the damage and vibrations of the bottom slab, and the inverted U-shaped slab could relieve the damage of the AAC blocks layer dramatically. Furthermore, based on the finite element (FE) program LS-DYNA, the corresponding refined numerical simulations are performed. By comparing the experimental and numerical damage and vibration accelerations of the composite structures, the present adopted numerical algorithms, constitutive models and parameters are validated, which will be applied in the further assessment of drop impact effects of full-scale SFC and FA on prototype nuclear fuel reprocessing plant in the next Part II of this paper.

Jeju Special Self-Governing Province has implemented a self-governing environmental impact assessment system (Jeju-EIAS) in recognition of its autonomy. In this study, the institutional features of Jeju-EIAS were examined by analyzing the development projects whose consultation under Jeju-EIAS were completed from 1994 to 2019. The consultation procedure of Jeju-EIAS, such as the actual operation of Review Committee for Environmental Impact Assessment (EIA), the consent of the provincial council, and the regular follow-up activities for the implementation of EIA consultations, has been implemented differently from those of other metropolitan cities and provinces. Under Jeju-EIAS, types of development projects subject to consultation on EIA also take into account local conditions, and include the construction of aquarium basin and building. In addition, provisions concerning the scale of development projects is strengthened above the Korean Environmental Impact Assessment Act (EIA Act).

An auditory experiment was conducted to establish annoyance criteria for floor impact noise in apartment buildings. Heavyweight floor impact sounds were recorded using an impact ball; the impact sound pressure level (SPL) together with the temporal decay rate (DR), which is quantified by the dB drop per second, was analyzed. For the experiment, A-weighted exposure levels of the heavy-weight floor impact sounds ranging 34~73 dB were evaluated at 3 dB intervals. Participants used a 7-point verbal scale to evaluate the level of annoyance from floor impact noise. The results show that the annoyance increases with increasing impact SPL and decreasing DR. Consequently, a classification and an acceptable level of floor impact sounds were proposed.

This paper assessed environmental impacts of marine sand mining on coastal areas and Exclusive Economic Zones (EEZs) of Korea, and diagnosed problems of the related assessment statements for suggesting key assessment items (scoping) and system improvement. To mitigate conflicts and environmental impacts caused by large-scale, concentrated sand mining, we suggest it is critical to promote sustainable and eco-friendly utilization of marine resources while listening opinions from various stakeholders and analyzing alternative plans. Especially, it should be mandatory as a scoping item to provide verifiable data on the amount of sand, potential and accumulative impacts by mining, and key assessment items (e.g. erosion and sedimentation by submarine topography, benthic change, spreading of suspended solids, water pollution, grain-size change, and impact on fisheries resources). We also suggest that postassessment and monitoring should be improved to enable tracking of environmental impacts caused by sand mining through seasonal monitoring together with intermittent short-term surveys. In addition, effective measures to mitigate the impacts is also essential. As repeated sand mining at large-scale can damage marine ecosystems by long-term accumulated impacts, we suggest that assessment systems and regulatory policies should be developed and established, especially for ensuring reliability of assessment and review on selected major sandmining projects.
