In this paper we examined a novel extension of the convergence empirics for the maritime business cycle which considers structure breaks and/or changes. To provide theoretical justification, the convergence hypothesis uses the relaxed assumption to technology shocks. Based on the recent empirical results provided by Kim and Chang (2020), we consider nonlinear dynamics that capture the properties on structural changes in the equilibrium adjustment process. This approach bridges the gap between the theoretical framework and empirical specifications. In particular, we applied the convergence hypothesis to the multiple structure change model for the maritime business cycle. Our application to the maritime data showed support of the convergence hypothesis allowing multiple structure changes during the high volatile period and offers additional insight into the forecasting maritime business cycles.

The purpose of this study was to delve into the features of paradigm in conjunction with changing convergence culture in the 21st century's knowledge-based society, the influence of convergence paradigm on fashion, and changes in convergence culture. After identifying the features of the paradigm of knowledge-based society in association with changing convergence culture, the characteristics of fashion paradigm were examined in con=junction with the characteristics of the paradigm, and the convergence phenomena of modern fashion were investigated to figure out fashion trends. The findings of the study were as follows: According to the features of ubiquitous technology based on the theories of Mark Weiser and other futurologists, the characteristics of changing convergence culture in knowledge-based society could be classified into invisibility, relationship and materialized virtuality. When relevant theories were reviewed, invisibility, relationship and materialized virtuality are identified as the unique features of the paradigm of changing convergence culture in knowledge-based society. But those characteristics aren't separate concepts. Instead, they are being connected and fused together, thanks to universalized digital technology and ubiquitous technology. Changing convergence culture has brought a change to fashion paradigm as well. There is a type of design that lets all the characteristics stand out, and another design fuses just some of them together conceptually or formally. That is, fashion paradigm is marked by a combination of invisibility, relationship and an embodiment of virtual reality to be in line with changes in convergence culture.

Recently, research on flexible sensors for personal health management has been gaining attention. In this study, we fabricated a crack-based flexible sensor in thin film form to measure the pulse on the wrist. We evaluated the characteristics of the sensor based on the curing conditions of the PDMS (Polydimethylsiloxane) film to optimize the sensor's gauge factor. The modulus of PDMS varies depending on the curing conditions. In this case, the modulus of PDMS has a significant influence on crack formation, leading to changes in the sensitivity of the sensor. This study examined the changes in the gauge factor associated with these variations.

현대사회의 다양하고 복잡한 사회적 문제를 해결하기 위해서는 융합적 시각의 문제 분석과 해결책 모색이 필요하다. 이러한 의미에서 융합연구의 중요성이 더욱 강조되고 있으며 효율성과 효과성 제고를 위한 전략적 접근이 요구되고 있다. 본 연구에서는 융합연구개발 활성화 기본계획의 텍스트 분석을 통하여 융합연구 정책의 시기별 특성과 시기별 토픽의 연관성과 변화추이를 확인하고 이를 통해 기본계획이 제시하는 정책적 변화를 이해하고자 하였다. TF-IDF 분석, 토픽 모델링(LDA), 그리고 네트워크(CONCOR) 분석 등 다양한 분석 방법을 활용하여 각 시기별 핵심 토픽을 도출하여 정책 변화 추이를 파악하였다. 분석결과, 시기별 토픽의 군집화와 토픽의 변화를 확인하였고 융합연구 생태계 조성과 당면한 과제 해결을 위한 융합연구의 방향성을 제시하고 있다는 것을 파악할 수 있었다. 본 연구 결과는 향후 거시적 관점에서 융합연구개발 활성화 정책 수립 시에 정책의 변화에 대한 새로운 통찰을 제공함으로써 정부, 기업, 학계, 연구기관 등 다양한 이해관계자들에게 중요한 시사점을 제공할 수 있을 것으로 기대한다.

Recently, to improve the effectiveness of education to learn from textbooks, immersive 3D environments such as virtual reality(VR) has been widely used for education. In this paper, in order to intuitively present education about content scenarios on changes in the human body according to food intake, we consist an immersive virtual reality environment to express the same life-size organs. The participants in our educational system showed higher results in all items compared to the existing textbook-based education such as immersion, understanding, and quality of education program. Also it was found the importance of interactivity to increase the effectiveness of immersive class.

본 논문은 디지털과 IT로 대변되는 현대의 융복합문화속에서 사회 문화적 요인이 반영된 변화를 요구받는 가구디자인의 특징에 관해 연구하고자 한다. 이를 위한 구체적인 방법으로서 기능주의로 대변된 산업혁명 이후의 디자인과 20세기 이후 다원화된 사회의 모습을 담아냈던 멤피스 그룹의 사례를 보려 하며 이를 토대로 융복합적 가치관이 보편화된 현대사회 속에서 변화를 요구받는 가구디자인의 모습을 조명하려 하였다. 이렇듯 미래의 가구디자인을 예측하는데 있어 사회구성원들의 가치관이 수용된 사회문화적 요인은 반드시 주지해야 할 중요한 요인임을 밝히는데 본 논문의 목적이 있으며 현대가구디자인의 주요 요소가 되었음을 인지하여 이를 바탕으로 폭넓고 깊이 있는 디자인 연구가 이루어져야 할 것이다.

The phase transition temperatures of CsCoCl₃·2H₂O crystals are investigated via differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Three endothermic peaks at temperatures of 370 K (=T_C1), 390 K (=T_C2), and 416 K (=T_C3) were observed for phase transitions from CsCoCl₃·2H₂O to CsCoCl₃·1.5H₂O, to CsCoCl₃·H₂O, and then to CsCoCl₃·0.5H₂O, respectively. In addition, the spin-lattice relaxation time T_1ρ in the rotating frame and T₁ in the laboratory frame as well as changes in chemical shifts for ¹H and ¹³³Cs near T_C1 were found to be temperature dependent. Our analyses results indicated that the changes of chemical shifts, T_1ρ, and T₁ are associated with structural phase transitions near temperature T_C1. The changes of chemical shifts, T_1ρ, and T₁ near T_C1 were associated with structural phase transitions, owing to the changes in the symmetry of the structure formed of H₂O and Cs⁺ ions. Consequently, the structural symmetry in CsCoCl₃·2H₂O crystals based on temperature is discussed by the environments of their H and Cs nuclei.

In the Fourth Industrial Revolution era, with its accelerating radical changes and innovation, fashion is rapidly advancing to sustain social changes introduced by technological convergence. In light of this, the study investigates the social and cultural characteristics of technologizing fashion products: creative modifications emerge from technological convergence with fashion products and result in a realm separate from technology. By focusing on the nature of fashion, this study analyzes the technologization of fashion products for added value creation in the fashion system. Based on the findings, it interprets different attitudes toward technologizing that changes fashion products. Accordingly, this study reviews previous literature and qualitatively examines empirical cases based on inductive reasoning. In particular, it analyzes commercialized cases of fashion-technology convergence in fashion products found on online fashion media outlets between January 2007 and May 2021, a central period in intellectual and technological innovation. The characteristics of technologized fashion products are identified as follows: expansion of physical functions and categories, interaction with emotional sensibilities, artistry through combination with technologies, and computer-generated imagery(CGI) fashion as digital goods. Therefore, this study analyzes the characteristics of technologization, focusing on the social and cultural properties of fashion products. The findings provide opportunities to understand the paradigm shift of these products that was catalyzed by technologizing.

This paper investigates the performance consequence of strategic changes when firms move closer to or further away from other firms in the industry. The study suggests a theoretical framework and hypotheses on the effect of strategic convergence and divergence on performance, and tests hypotheses with firm-level longitudinal data on the U.S. food processing industry during the period of 1985-2000. The study shows that strategic divergence is negatively related to performance, and that organizational size and firm-specific uncertainty significantly influence the effect of strategic convergence and divergence on financial performance. Particularly, high uncertainty seems to be conducive to financial performance improvement for organizations undergoing significant strategic changes converging toward other competitors. On the other hand, big organizational size seems to be beneficial for finns implementing strategic changesdiverging from other competitors.
