Adhesive bonding has seen rapid development in recent years, with emphasis to composite patch repairing processes of geometric defects in aeronautical structures. However, its use is still limited given its low resistance to climatic conditions and requirement of specialized labor to avoid fabrication induced defects, such as air bubbles, cracks, and cavities. This work aims to numerically analyze, by the finite element method, the failure behavior of a damaged plate, in the form of a bonding defect, and repaired by an adhesively bonded composite patch. The position and size of the defect were studied. The results of the numerical analysis clearly showed that the position of the defect in the adhesive layer has a large effect on the value of J-Integral. The reduction in the value of J-Integral is also related to the composite stacking sequence which, according to the mechanical properties of the ply, provides better load transfer from the plate to the repair piece through the adhesive. In addition, the increase in the applied load significantly affects the value of the J-Integral at the crack tip in the presence of a bonding defect, even for small dimensions, by reducing the load transfer.

Purpose: Natural products are becoming gradually popular because of their health - related benefits and consumers' environmental awareness. However, research in this field remains limited, the present study attempts to address this research gap by measuring the influencing levels of the antecedents on natural product brand love. Research design, data and methodology: The study employs S-O-R (Stimulus - Organism - Response) framework together with Innovation Resistance Theory and Dual-Factor Theory to propose the research model, in which health and environmental stimuli influence both of facilitators and inhibitors of internal states or organism, and then shape purchase intention and brand love as consumers' responses. The mixed research method is designed with the application of structural equation model (SEM) to analyze 530 consumers collected by convenience sampling. Results: The results revealed that two chosen stimuli, including health awareness and environmental concern were positively related to both facilitators (natural content and regional products) and inhibitors (image barrier and usage barrier) and these four factors were significantly associated to purchase intention and brand love. Furthermore, purchase intention played the mediating role on the relationship between the four organisms and brand love. Conclusions: The originality of this paper is extend S-O-R theory into natural product context with mediating effects in an emerging economy. The findings make theoretical contribution on consumer behavior and managerial implication.

Metal additive manufacturing (AM) has transformed conventional manufacturing processes by offering unprecedented opportunities for design innovation, reduced lead times, and cost-effective production. Aluminum alloy, a material used in metal 3D printing, is a representative lightweight structural material known for its high specific strength and corrosion resistance. Consequently, there is an increasing demand for 3D printed aluminum alloy components across industries, including aerospace, transportation, and consumer goods. To meet this demand, research on alloys and process conditions that satisfy the specific requirement of each industry is necessary. However, 3D printing processes exhibit different behaviors of alloy elements owing to rapid thermal dynamics, making it challenging to predict the microstructure and properties. In this study, we gathered published data on the relationship between alloy composition, processing conditions, and properties. Furthermore, we conducted a sensitivity analysis on the effects of the process variables on the density and hardness of aluminum alloys used in additive manufacturing.

Leuconostoc lactis strain DMLL10 was isolated from kimchi, a fermented vegetable, as a starter candidate through safety and technological assessments. Strain DMLL10 was susceptible to ampicillin, chloramphenicol, clindamycin, erythromycin, gentamicin, kanamycin, streptomycin, and tetracycline. It did not show any hemolytic activity. Regarding its phenotypic results related to its safety properties, genomic analysis revealed that strain DMLL10 did not encode for any toxin genes such as hemolysin found in the same genus. It did not acquire antibiotic resistance genes either. Strain DMLL10 showed protease activity on agar containing NaCl up to 3%. The genome of DMLL10 encoded for protease genes and possessed genes associated with hetero- and homo-lactic fermentative pathways for lactate production. Finally, strain DMLL10 showed antibacterial activity against seven common foodborne pathogens, although bacteriocin genes were not identified from its genome. These results indicates that strain DMLL10 is a novel starter candidate with safety, enzyme activity, and bacteriocin activity. The complete genomic sequence of DMLL10 will contribute to our understanding of the genetic basis of probiotic properties and allow for assessment of the effectiveness of this strain as a starter or probiotic for use in the food industry.

Recently, there is a substantial interest in implementing Business Process Management System(BPMS) among enterprises with the purpose of business process innovation. BPMS redesigns and coordinates business processes in terms of both automated steps and human involvement in order to maximize the value of both involved people and systems. The reason why BPMS is getting attention from top managers is that it has the possibility to optimize the business processes by cycling the process of modeling, execution, monitoring, evaluation, and redesigning work processes. Thus, it has created high expectations about not only productivity improvement but also business process innovation. However. having an innovative nature, which is used for process innovation, BPMS implementation has great potential to stir up employee resistance. The analysis and the discussion about the prevention of the resistance against IS(Information Systems) is important because IS change the way people work and also alter the power structure within the organization, in general. The purpose of this study is to investigate factors that have an impact on the effective adoption of BPMS at the enterprise level. To find out these factors, this study considers two characteristics of BPMS: First. BPMS shares some characteristics with other enterprise-wide IS such as ERP. Second, it has special BPMS-specific characteristics. Due to the lack of previous research on BPMS adoption, interviews were carried out with IT-consultants and CIOs who conducted BPMS projects previously to find out BPMS-specific features that would make BPMS unique when compared to other enterprise-wide IS. As a result, the monitoring function was chosen as the main BPMS-specific factor. Thus, this paper reviewed studies both on enterprise-wide IS adoptions, which applied Technology Acceptance Model (TAM) and secondly on computer based monitoring to find out factors that would influence the employees' perception on the monitoring function of BPMS. Based on the literature review, the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses, out factors that would impact the employees' perception on the monitoring function of BPMS. Based on the literature review the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses. The data analysis results showed that two among three monitoring function related factors - enterprise evaluation system and fairness of the boss - were significant. This implies that employees would worry less about the BPMS implementation as long as they perceive the monitoring results will be used fairly for their performance evaluation. However, employees' high self-efficacy on their job was not a significant factor in their perception of the usefulness of BPMS. This is related to cases that showed employees resisted against the information systems because they automated their works (Markus, 1983). One specific case was an electronic company, where the accounting department workers were requested to redefine their job because their working processes were automated due to BPMS implementation.

본 연구에서는 인천광역시 소하천인 굴포천, 장수천, 승기천, 공촌천의 자연형 하천복원 사업에 따른 환경가치를 추정하기 위하여 컨조인트 분석을 이용하였다. 또한 지불용의액을 추정하여 최소의 비용으로 최대의 행복감을 줄 수 있는 조건을 분석하였다. 분석결과, 지불용의액은 15,000원 정도면 수긍할 수 있는 것으로 나타났다. 하천형태에서는 '자연형', 수변공간에서는 '홍수터+산책로+편의시설'이, 수심에서는 10 cm이상이 가장 수긍할 수 있는 요인으로 나타났다. 그러나 15,000원으로는 모든 조건을 충족할 수 없을 것이다. 소요 비용을 높게 책정하게 될 경우 지역 주민의 조세 저항에 부딪치게 될 확률이 매우 높다. 따라서 속성 수준의 분석결과를 고려하여 5가지의 대안을 도출하였다. 본 연구의결과는 인천시 주민의 설문결과로서, 인천시 자연형 하천사업의 환경가치를 추정하는데 컨조인트 분석을 시도하였다는 점에서 의미 있다. 향후 추정하고자 하는 연구 대상의 특성화된 요인을 반영하고, 하천이 가진 보다 다양한 속성을 다각적 분석을 통하여 정확한 환경가치를 추정한다면, 활용성이 높은 연구가 될 수 있을 것으로 판단한다.

이 연구는 메이커 운동과 관련된 단행본, 정책 보고서, 기사 및 칼럼 등을 비판적 담론 분석의 관점에서 살펴보며 메이커 문화를 둘러싼 담론적 지형과 사회적 실천을 분석한다. 정부 주도의 메이커 운동은 제작 문화를 경제 위기를 극복할 수 있는 '창조 경제'의 원동력으로 의미화하고, 디지털 제조업의 창업을 정책적으로 진흥하고 있다. 서울시의 경우, 정부 주도의 경제주의적 메이커 운동을 비판하면서, 기술을 통해 사회 문제를 해결하고자 하는 '디지털 사회 혁신'으로 메이커 운동을 제도화한다. 문화 예술계에서는 메이커를 장인 노동이나 손노동과 같은 '창조적 장인'으로 간주한다. 또한 지배적인 기술 구조에 대한 대항으로서 '비판적 제작 활동'을 구축하고자 하는 저항의 움직임도 있다. 하지만 지배적 담론이 현실적인 차원에 미치는 권력 효과와, 대항적 담론 투쟁으로 인한 지배 구조의 균열을 섣불리 확신할 수 없다. 현재 진행 중인 메이커 운동은 지배적인 권력 구조와 접합되어 제작 문화를 사회적 경제적 가치로 이끌어 내고자 하는 담론 전략과, 이에 대한 문화적 기술 정치적 가능성을 중시하는 대안적인, 혹은 대항적인 의미화 실천이 경합하는 갈등과 투쟁의 장이다.
