토마스 쿤의 패러다임 이론은 수학의 혁명적 과정을 설명하는 데는 충분치 않으며, 학제간 연구에는 더욱 그러하다. 본 논문에서는 현대건축에 나타난 위상기하적인 요소를 고찰하고, 우리나라 전통건축과 서양의 현대건축과의 강한 유사성을 비교할 때 시대정신으로는 설명이 불충분하여 범 패러다임이란 개념으로 설명한다.

요즘 지식과 앎(knowing)에 대한 새로운 인식론적 패러다임으로 떠오르고 있는 구성주의(constructivism)에 접하여 여러 가지 학습 방법들이 제시되고 있으나 체계적이고 획기적인 대안이 나오는 것은 아니다. 구성주의를 주창하는 사람들이 제안하는 교수 학습 방법은 이미 관심 있는 교사들이 실천하고 있는 학습 방법이다. 이런 맥락에서 교실 현장에 밀접한 연구 결과와 많은 학습 방법을 제시한 Richard Skemp의 이론을 구성주의에 비추어 해석하고 그의 수 개념 기초를 위한 여러 놀이 활동을 소개하고자 한다.

Vocabulary learning plays an important role in language learning. This study explored a new paradigm based on social networking site (SNS) supported collaborative learning for vocabulary learning. SNS supported collaborative learning (SSCL) can effectively promote learners' engagement, interest and motivation by providing a more communicative and interactive environment. However, vocabulary learning studies on SSCL mainly focused on the effectiveness and influencing factors, lacking specific instructional strategies. Therefore, this study aims to develop instructional strategies that guide instructors to create an SSCL environment for facilitating vocabulary learning. The final instructional strategies are composed of three stages according to the course process, consisting of 8 general strategies and 21 specific guidelines. The content validity was ensured by four experts in the field of educational technology. The instructional strategies were then applied in an actual classroom with 16 students. The positive responses from the instructor and learners indicated that SSCL can be reasonably incorporated into the current curriculum to provide effective learning opportunities and to promote learners' vocabulary learning.

Objective: Service industry has become the most important industry among various economic activities, as the percentage of service related industry in advanced nations is over 60% of their GDP and the percentage of service industry in South Korea, a traditional manufacturing nation, now takes up over 60% of the entire economy. Background: Such industry paradigm shift has changed consumers from those that simply purchased products into groups of people that evaluate the companies that manufacture products, thereby further intensifying competition among companies and increasing the importance of integrated communication between companies and consumers. However, the excessive existence of sub-identities that have been developed for integrated management of the existing corporate identities, as well as the undifferentiated general management strategies by companies are creating confusion not only for consumers but also for various corporate interest parties. In addition, service identity strategy has become the most important strategy than any other sub-identity strategies in forming corporate identity at the increased importance of corporate service in the era of service industry. However, the current domestic circumstance is that the concept of service identity has not been well established through specific related studies. Method: Accordingly, the existing academic and field studies on the corporate identity(CI), brand identity(BI) and product identity(PI) used for the communication with consumers were reviewed in this study to establish and summarize the concept of service identity(SI) that appeared at the service economization. Results: The purpose is to examine the kind of change that could be brought about by SI for the corporate integrated identity strategy developed through the existing corporate, brand & product image in order to present a new direct in corporate identity strategy according to the industry paradigm shift through a SI centered new corporate identity framework. Conclusion: For preparing the new era of service industry, the corporate integrated identity strategy must be integrate with concept of service identity and which is essential to differential from other companies. Application: The proposed concept and framework of service identity on this paper will help to understand and clearly define why service identity is important factor of the new idea of corporate identities.

In recent, cloud computing paradigm and open source as a huge trend in the Information Communication Technology (ICT) are widely applied, being closely interrelated to each other in the various applications. The integrated services by both technologies is generally regarded as one of a prospective web-based business models impacting the concerned industries. In spite of progressing those technologies, there are a few application cases in the geo-based application domains. The purpose of this study is to develop a cloud-based service system for satellite image processing based on the pure and full open source. On the OpenStack, cloud computing open source, virtual servers for system management by open source stack and image processing functionalities provided by OTB have been built or constructed. In this stage, practical image processing functions for KOMPSAT within this service system are thresholding segmentation, pan-sharpening with multi-resolution image sets, change detection with paired image sets. This is the first case in which a government-supporting space science institution provides cloud-based services for satellite image processing functionalities based on pure open source stack. It is expected that this implemented system can expand with further image processing algorithms using public and open data sets.

In this paper we study the effect of chaos in nonuniform instability with optical fiber based IoT networks. The transient response of optically controlled fiber has also described. Nonlinear optical fiber effects especially fiber scattering in networks has emerged as the essential means active optical devices. The paradigm instability in fiber Internet serves as a test for fundamental study of chaos and its suppression and exploitation in practical application in optical communication. This paper attempts to present a survey and some of our research findings on the nature of chaotic effect on Internet based optical communication. The transient response in optical fiber has been evaluated theoretically by calculating the variation of the scattering function. The lines has used under open ended termination containing optically induced region. The scattered optical waves in a fiber used in optic communications are temporally unstable above certain threshold intensity.

Objective: Recent studies have challenged the traditional paradigm that growth hormone receptor (GHR) displays physiological functions only in the cell membrane. It has been demonstrated that GHR localizes to the cell nucleus and still exhibits important physiological roles. The phenomenon of nuclear localization of growth hormone (GH)-induced GHR has previously been described in vitro. However, until recently, whether GH could induce nuclear localization of GHR in vivo was unclear. Methods: In the present study, we used pig as an animal model, and porcine growth hormone (pGH) or saline was injected into the inferior vena cava. We subsequently observed the localization of porcine growth hormone receptor (pGHR) using multiple techniques, including, immunoprecipitation and Western-blotting, indirect immunofluorescence assay and electronmicroscopy. Results: The results showed that pGH could induce nuclear localization of pGHR. Taken together, the results of the present study provided the first demonstration that pGHR was translocated to cell nuclei under pGH stimulation in vivo. Conclusion: Nuclear localization of pGHR induced by the in vivo pGH treatment suggests new functions and/or novel roles of nuclear pGHR, which deserve further study.

Live Commerce is rapidly emerging as a new paradigm for the digital economy and consumption activities in the post-COVID era. Many prior studies have been conducted on Live Commerce, but studies focusing on the characteristics of sources of Live Commerce are insufficient. This study aimed to investigate the human factors of sources that affect consumers' intention to use Live Commerce. For this purpose, based on an expanded TAM (Technology Acceptance Model) through literature research, variables were set, and a survey was conducted targeting Korean consumers who have experienced purchasing products through Live Commerce. Excluding unreliable data, 201 responses were utilized in the analysis of this study. At first, the measurement tools were checked through validity and reliability verification, and correlation analysis was conducted to identify the relationships between variables. Then, the proposed hypotheses were verified through multiple regression analysis. As a result, firstly, the human factors of sources had a positive effect on PU (Perceived Usefulness). Secondly, the PEOU (perceived ease of use) had a positive effect on both PU and CS (Consumer Satisfaction). Thirdly, PU had a positive effect on CS and ITU (Intention to Use). Finally, CS with Live Commerce had a positive effect on the ITU. Through this study, we try to provide an understanding of consumer behavior in the Live Commerce environment and contribute to enhancing the service provider's ability to offer high-quality Live Commerce content.

Paperless trade is a new trade paradigm that has innovated on traditional trade procedures, which relied on manual work in the past, and applied an IT-based e-document standard. To realize paperless trade in Korea, a lot of efforts have been made. Korea has overcome many difficulties, a lack of awareness, trials and errors, etc. at the initial introduction stage and strived to establish a stable infrastructure through the government's policy support and active cooperation with the trade business communities and related organizations. Now, Korea became a well-known leader in IT industry, especially in the paperless trade infrastructure and strategic policies. The one-stop trading system named 'uTradeHub' is operated by a paperless trade service provider, Korea Trade Network(KTNET). uTradeHub includes trade finance and settlement, customs clearance and export and import logistics, improving trading procedures and reducing related expenses. Private-Public joint efforts from Korean government and private sectors which have respectively fulfilled their role and function with market-oriented practical policies and strategies has lead Korea a world leading country in paperless trade. Moreover, Korea expended its efforts to the global areas. Korea has started to activate multi-national paperless trade alliances such as PAA(Pan-Asia e-Commerce Alliance), ASEAL(Asia Europe Alliance for Paperless Trading) as well as established the bilateral cooperative networks with China and Taiwan. The one-stop trading system, uTradeHub should keep close cooperations between nations since trade itself is implemented in a cross-border ways. In the near future, it is expected uTradeHub can achieve best results in the simplification of procedures and cost savings when an international linkage is completely established with international cooperations.
