해상특수교량은 특수한 환경적 조건뿐 아니라 고주탑의 구조형식, 보호재로 쌓여있는 케이블 등 특 수한 형식을 가지고 있어 일반적인 육안전검으로 안전점검을 할 수 없는 사각지대가 존재한다. 주탑의 외부 손상상태 및 케이블의 손상에 대해서는 정밀안전점검에서도 점검이 되지 않는 경우가 대부분이 므로 이에 대한 대책 마련이 시급하다. 또한 해상특수교량에 대한 전문적인 경험과 기술이 부족한 관 리자도 대상교량의 손상과 이상거동을 직관적으로 확인하고 판단할 수 있는 지원체계가 필요하다. 이 에 본 연구에서는 해상특수교량 고주탑에 대한 손상정보를 파악하기 위하여 드론의 자동비행 기술을 개발하고 이를 이용하여 주탑 외부 균열 손상에 대한 안전점검을 실시하고 이를 분석하였다.

Plastics are widely used in industries in human society and because of their structural stability, degradation is a serious global issue. To estimate the degradation of plastic, 31 edible mushrooms were cultured with the selected plastic films (polyethylene [PE], polystyrene [PS], and poly(ethylene terephthalate) [PET]) for 3 months at 25 °C. Measuring the weight of the films showed that four species of mushrooms, namely Porostereum spadiceum, Ganoderma lucidum, Coprinellus micaceus, and Pleurotus ostreatus, exhibited the highest degrees of plastic degradation. In addition, the mushrooms and fungi that exhibited the most significant plastic degradation were cross-cultured to promote this degradation. As a result, cross-cultivation of G. lucidum and Aspergillus niger showed a weight loss of 2.49% for the PET film. For the PS film, Aspergillus nidulans showed a weight loss of 4.06%. Cross-cultivation of A. nidulans and C. micaceus, which showed a weight loss of 2.95%, was noted as an alternative for PS biodegradation, but is harmful to humans. These bio-degradation effects of edible mushroom will contribute to the development of alternatives for eco-friendly plastic degradation.

본 연구는 애니메이션 <만약...헬라가 텐 링즈를 발견한다면?>을 사례 로 의상 기호의 의미와 의복 문화의 이데올로기가 내러티브에 미치는 영 향을 분석함으로써 기호가 애니메이션 서사에 미치는 지도적 역할을 탐 구하고자 하였다. 연구는 다양한 문화적 환경에서 의상의 색상, 스타일, 소재가 갖는 부가적 의미와 의상 기호가 갖는 이데올로기를 롤랑 바르트 의 기호학을 통해 분석하고, 애니메이션에서 의상 기호의 서사적 역할과 애니메이션의 주제적 아이디어 전달에 대해 연구하였다. 연구 결과에서 는 애니메이션 작가들은 의상 기호를 활용하여 시각적 서사적 도움을 주 고 있으며, 기호의 통합을 통해 작가가 표현하고자 하는 주제적 아이디 어를 설명하고, 관객이 애니메이션 속 플롯의 전개와 등장인물의 감정 변화를 이해하고 느낄 수 있도록 돕고 있다. 이 연구의 결론은 기호학이 애니메이션 서사와 통문화적 기호 사용에 대한 이야기를 전달하는 데 도 움이 되는 아이디어를 제공하고, 더 나은 애니메이션 작품 창작에 학술 적 지원을 제공한다. 그러나 기호를 의상 층면에만 한정함으로써 애니메 이션 전체의 시각적 의미 전달에 대한 지침으로서 많은 한계가 있다.

이 글은 웹소설 <소녀, 홍길동>(2019)에 나타난 남장 서사를 중심으로 고전소설의 남장 서사 주체와 비교를 통해 우리 시대의 주체성에 대해 진단하는 것을 목적으로 한다. 지금까지 로맨스 웹소설 연구에서는 로맨 스 장르의 문제성이나 웹소설의 상업성과 통속성을 폭로하는 것이 대부분이었다. 이 글은 주체성의 측면에 서 바라보았을 때 시대정신과 관련해 변화된 부분이 더 중요하다고 생각했다. 그래서 작품 속 남장 서사를 고전소설의 것과 비교해본 결과, 남장이 로맨스를 조장하는 수단으로 활용되고 있으며 무엇보다 욕망을 은폐시킨 주체의 모습을 발견할 수 있었다. 이런 로맨스 웹소설의 낭만적 사랑은 기존 로맨스 소설의 문법을 일정 부분 따르면서도, 조금 다른 방식으로 로맨스를 형상화한 것이다. 기존 로맨스에서는 완벽한 ‘나’를 찾으려는 욕망이 내재해 있고, 이것은 진정성의 주체를 생산한다. 그러나 <소녀, 홍길동>에는 이러한 시도들이 부재하며, 오로지 상대방의 욕망 안으로 주인공의 욕망이 한정되기에 사랑‘만’을 읊조리는 유아 적이고 자폐적인 주체, 즉 ‘포스트-진정성’의 주체가 생산되었다. ‘포스트-진정성’의 주체는 환상성에 기대 고 있고, 이 환상은 생존을 중시하는 사회와 속물주의에 근원하고 있다. 이에 필자는 웹소설 장르가 환상성 이 아닌 상상력을 기반으로 한 새로운 주체 생산으로 가야할 것을 제안했다. 그것은 유목적 주체로, ‘타자 되기’를 통해 미래에 다가올 시대에 발맞춰 K-서사의 올바른 방향을 설정할 수 있으리라 본다.

글로벌 시대에 영화는 문화와 오락의 매개체일 뿐만 아니라 사회 문화 현상을 반영하는 중요한 방법이기도 하다. 다문화 영화 작품은 전 세계 관객들의 관심을 유도하는 동시에 작품 고유의 문화적 특색도 유지해야 한다. 본 연구는 2022년 픽사 애니메이션 스튜디오가 선보인 <메이의 새 빨간 비밀(Turning Red)>을 연구 대상으로 삼아 3막 서사 구조 분석 방 법을 활용해 해당 영화가 홉스테드(Geert Hofstede) 문화차원 이론(Hofstede Culture Dimension Theory)을 어떻게 구현했는지 살펴보고자 한다. 이 영화는 메이가 동서양 문화가 합쳐진 환경 속에서 어떻게 질풍노도의 청 소년기를 극복하고, 점차 자아를 발견하고 자신의 내면과 화해를 이루는 지 그 과정을 보여준다. <메이의 새빨간 비밀>의 서사 구조는 설정, 대 립, 해결의 세 가지 부분으로 명확하게 구분되어 관객이 영화를 이해하고 몰입하는 데 도움이 된다. 이 영화의 서사 전략은 홉스테드 문화차원 이 론을 교묘하게 활용하고, 캐릭터 간의 상호작용과 플롯 전개를 통해 다문 화 배경 속에서 개인의 성장 과정을 보여주는 것이다. 본 연구는 <메이의 새빨간 비밀>이 어떻게 3막 구조와 홉스테드의 문화차원 이론을 결합해 스토리를 구축하고, 이 이론들을 같이 활용해 관객들의 관심을 끌고 문화 적 공감대를 이끌어냈는지 연구하는 것을 목적으로 한다.

The automotive industry continuously strives to enhance safety for both drivers and passengers through technological advancements. Car side impacts have the potential to significant risks to passengers, So the automotive industry has proposed various technological solutions. As part of these efforts, the development of side impact beams, which are affixed to the inner frame of vehicle side doors to absorb and dissipate collision energy, has been a safety enhancement. Conventional side impact beams are manufactured using hot-rolled steel sheets and have a pipe-like configuration. However, these impact beams are fixed to the vehicle's chassis, which directly transfers the energy generated during a collision to the chassis frame. This paper aims to address this issue by proposing the development and optimization of vehicle door impact beams using a dual-beam structure and fastening method, utilizing shear bolts. Moreover, the focus is on optimizing the cross-sectional shape of the dual-beam impact structure. The evaluation criterion for optimization is based on the second moment of area of the cross-section. To validate these improvements, Static experiments were conducted, comparing the proposed dual-beam structure with the traditional impact beam. This research is expected to serve as a guideline for enhancing vehicle safety through design directions and validation methods.

Background: A decrease in physical activity has been observed due to the global pandemic, resulting in the onset and progression of musculoskeletal disorders as chronic diseases. Objectives: This study aimed to assess the difference in the degree of contraction of the lower limb muscles between the existing vertical vibration method and a new cross-vibration method. Design: Randomized controlled trial. Methods: The exercise program using whole-body vibration equipment was conducted for 12 sessions, 25 min per session, three times per week for 4 weeks. Results: The changes over time showed a significant difference in cross-alternating vibrations (P<.05), except for the lateral gastrocnemius and tibialis anterior, with no significant difference in sonic vertical vibration (P>.05). The interaction between time and group was significant for all muscles (P<.05), except for the biceps femoris, with differences between before the program and at 2 and 4 weeks after the program revealed in the post-hoc analysis. Conclusion: Future studies should further evaluate the use of CAV exercise devices as auxiliary equipment in exercise by assessing different groups and variations in intensity.

Background: Smartphone addiction has emerged as a significant social problem. Numerous studies have indicated the association between smartphone use and discomfort in the musculoskeletal system of the upper extremities. Objects: This cross-sectional survey aimed to compare the characteristics of musculoskeletal pain in the neck, trunk, and upper limbs between individuals with smartphone addiction and those without addiction. Methods: We collected a total of 326 healthy individuals’ data from China and Korea who had owned and used smartphones for more than 5 years between 20–50s through an online questionnaire consisting of 84 questions in four major sections. The first part contained basic information on the participant's personal characteristics and smartphones. The second part contained questions about smartphone use and posture. The third part was the smartphone addiction. The fourth part was to investigate musculoskeletal pain in various upper body parts. Results: Smartphone addiction has a weak negative correlation with age (r = –0.20, p < 0.01) and a weak positive correlation with the hours of smartphone use (r = 0.376, p < 0.01). Frequent musculoskeletal pain symptoms related to smartphone use were observed in the neck, shoulder, lower back, and wrists. The hours of smartphone use was slightly positively associated with the prevalence of musculoskeletal pain in the shoulder (r = 0.162, p < 0.05) and lower back (r = 0.125, p < 0.05). The prevalence of musculoskeletal pain in the neck (χ2 = 3.993, p < 0.05), shoulder (χ2 = 6.465, p < 0.05), and wrist (χ2 = 4.645, p < 0.05) was significantly higher among females than males. Conclusion: The results suggest that smartphone addiction should be recognized as a dual concern encompassing both physical health and psychosocial aspects. Furthermore, healthcare professionals, including physicians and physical therapists, should consider clients' smartphone usage patterns when assessing and treating with musculoskeletal pain.

Background: In terms of physical performance, elastic tape (ET) is known to contribute to injury prevention and performance enhancement. Objects: This study aimed to compare and analyze the effect on lower extremity muscle activity of young adult women with and without ET during squats. Methods: In this study, six healthy, young women were recruited as participants in a university laboratory. Participants were allocated to two groups of three after measuring muscle activity in a pre-test, and the experiment was conducted for a total of two weeks (two sessions). First, 10 half squats were taped once in the first week, and 10 half squats were performed without taping in the second week. The other group did this in reverse and measured muscle activity after the squat was over. Results: As a result of this study, there was no significant difference in the quadriceps with or without ET (Z = –0.11, p > 0.05). Similarly, no significant difference was found in hamstring (Z = –0.31, p > 0.05). Conclusion: No beneficial effect was found on changes in muscle activity following ET application during squats. Further studies require randomized controlled trials that increase the number of participants and the intensity of the intervention, and measure pain, function, and performance rather than muscle properties depending on the biomechanical lifting mechanism.

This paper aims at analyzing, throughout an Italian and American cross-cultural study, one of the phenomena which is booming in the fashion luxury sector: the resale market. It is evident that Covid-19 has boosted a deep transformation, that the world of luxury was already going through: a) the increased relevance acquired by the experiential consumption; b) platforms that offer new forms of digitalized buying experiences; c) request for sustainability.

This study investigates the effect of co-creation on psychological well-being and future co-creation intention on social media. Data were collected from the United Kingdom, Canada and Australia. Although the results suggest that the effects of co-creation on users may differ depending on context, they generally show that co-creation experience has a positive relationship with co-creation behavior, and that risk assessment moderates this relationship. Co-creation experience also has a positive relationship with psychological well-being, and co-creation behavior mediates this relationship. The results also confirm that co-creation behavior has a positive relationship with future co-creation intention, and co-creation behavior mediates the relationship between co-creation experience and future co-creation intention.

With the development of internet and communication technologies, diversification of consumer needs, and intensifying competition, omnichannel is spotlighted among retailers as one of the breakthroughs to survive. Particularly, among scholars and practitioners, cross channel integration (CCI) has been pointed out as a key concept to achieve success in omnichannel, and several successful cases of retailers and strategies implemented under CCI are reported. Nevertheless, due to the wide scope and complexity of CCI, as well as the substantial cost and long-term perspective required for its investment, CCI involves a high level of uncertainty and complicated decision-making. Thus, most retailers are still struggling in achieving the level of CCI that their consumers desire.

In most cultural contexts, consuming ethically is socially desirable and reporting favorable attitudes is relatively cost-free. Thus, consumers have incentives to state favorable attitudes toward ethical products despite barriers to actual purchase. This attitude-behavior gap in ethical consumption presents a global challenge to socially responsible marketing (Carrington et al., 2010, 2014, 2016). Several explanations for this gap have been offered. The current research draws from these explanations and—based on literature in psychometrics and attitude formation—develops a novel measurement tool based on the Affect Misattribution Procedure (AMP; Payne et al., 2005). We aim to capture consumers’ implicit ethical product attitudes which have otherwise evaded marketers (Zollo, 2021). Further, using samples of consumers in both the US and Italy, the current research examines the predictive power of this measure in predicting consequential ethical consumption choices. We conclude with a proposal for additional studies to further validate the procedure in more ecologically valid contexts.

In this conceptual paper, we use the multiple agency theory to explain the governance issues in cross-sector partnerships. In doing so, we identify five typologies of cross-sector partnerships, each distinct from one another in terms of the governance structure. We also discuss three problems that occur in these relationships, mainly differences in institutional logic, temporal differences, and free-riding and opportunistic behavior, as well as how these problems affect each type of cross-sector partnership. These findings make several significant contributions to the literature and theories. First, this is one of the few studies to use agency theory to examine the governance structures and problems in cross-sector partnerships. Second, our study further contributes to solidifying our understanding of the agency problems arising in cross-sector collaborations. Lastly, our study confirms their presence in other types of cross-sector partnerships as well and we maintain that these problems do not affect each type of cross-sector partnership in the same way, leading us to offer more nuanced implications for researchers and practitioners.

Prejudice refers to ideas, beliefs, feelings, and attitudes that people have about other less familiar groups as a whole or individuals within those groups, based on their perceived group membership (e.g., race, class, gender, and religion. Prejudice has become increasingly of major importance to scientific thinking about relations between groups. However, little is known about how prejudice affects consumer buying behavior, especially regarding shopping activities that involve crossing between suppliers.

As one of the biggest service-oriented industries worldwide, the hotel industry significantly contributes to environmental degradation in several ways. Service marketers, consumers, and policy makers are increasingly aware of the damage that excessive natural resources depletion in the guise of water and energy consumption and CO2 emissions by hotels might bring about to the planet. As a result of the growing global concern about climate change, there has been an increase in consumer demand for environmentally-responsible hospitality options. One such option is green hotels, which are environmentally-conscious hospitality properties that are gaining popularity worldwide at a rapid pace. Consumers who prioritize eco-friendliness are willing to pay a premium for green hotels. However, unlike tangible products, services such as hotel experiences are subjective, emotional, and therefore, difficult to evaluate before actual usage. One of the prominent ways in which consumers assess green hotels’ credibility is through user generated content in the form of reviews.
