In this study, the characteristics of digital anthropometric methods were determined with case studies. These methods were broadly classified into two categories: non-wearable and wearable. Then, these categories were further classified into four types: 3D Scanning, mobile app, smart clothing, and smart tool Among the non-wearable types, the "3D scanning" technique was based on the use of 3D hardware equipment. With this technique, the body shape was measured and the internal body information was obtained. Therefore, it is used in fields of healthcare and fitness. Among the wearable types, "Smart clothing" involves a special clothing that measures human body and a smartphone application. Both the components are linked to a fashion platform, which is based on the measured sizes that help shoppers. The "Smart tool" has the characteristic of measuring only with smart tools and smartphone applications; it does not involve the measurement of images. The common advantage of digital anthropometric methods are as follows: they reduce the time and cost of measurement by enabling self-measurement. Moreover, simple measurements are used to determine the size of anthropometry. Thereafter, it accumulates this data to track the continuous changes in size. From an industrial point of view, digital anthropometric technology should be used to increase sales. The on-demand market can be expanded as global consumers would throng the Korean fashion market. For the consumer, an avatar should be created to fit the user's size. This would provide a fun experience to the user.

Purpose - This study aims to conceptualize the construct of social media (SM) fatigue. Design/methodology/approach - A qualitative approach is employed to understand how SM users currently perceive (or interpret) the goals of SM usage and to conceptualize SM fatigue and its dimensions. We collected data through in-depth interviews of three SM users and group discussions among eighty SM users. Findings - we draw a definition of SM fatigue from a resource view that excessive SM use might lead to SM fatigue by depleting the internal resources of SM users. Further, through the analysis of the qualitative data from interviews and group discussions, we find the multi-dimensional nature of SM fatigue and identify five dimensions of SM fatigue-fatigue from the social obligation to interact with people, the importance of self-appearance, the quality of information, the quantity of information, and undesirable events-and common sources of fatigue in each dimension. Research implications or Originality - The conceptualization of SM fatigue elaborated in this study could enable scientific exploration of the role of SM fatigue in users' attitudes or behavior formation and change. On a practical front, this study would be valuable to companies by facilitating systematic investigations of their customers' fatigue through the lens of the SM fatigue dimensions.

Purpose - With the rapid development of information technology, the digital economy has become an important grip of the new development pattern, and the digital transformation of enterprises is a major trend. As SMEs are the mainstay of the economy and employment, it is important to study the digital transformation of SMEs to promote the development of the digital economy. Research design, data, and methodology - Based on a resource-based view, this report analyses the current situation and issues of digital transformation of SMEs from the perspective of digital orientation as well as the breadth and depth of technological capabilities of enterprises, using data from a survey of 200 manufacturing enterprises in China. Result - The results show that SMEs generally have a digital transformation mindset, but a weak digital foundation. In order to execute a digital strategy, companies need digital transformation capabilities. These behavioral capabilities are guided by the strategic direction of the business, and companies with strong capabilities are always trying to tap into the full digital potential. Conclusion - In order to effectively promote the digital transformation of SMEs, we suggest that SMEs pay attention to digital capability building, make good use of digital platforms and network resources, and lay a solid foundation for digital transformation; meanwhile, we suggest that government departments play a guiding and supporting role to build a cross-industry and cross-sector digital synergy system to help promote the development of SMEs' digital transformation. This paper presents some suggestions from both the internal and external environment of the enterprise, with the expectation of contributing to the digital transformation practices of SMEs.

21세기는 소비자의 내외재적 경험을 중시하는 경험경제(Experience Economy)의 시대라고 할 수 있으며 그 핵심은 새로운 관점에서 소비자의 욕구를 이해하는 것이다. 그간 전문가 중심적 관점의 디자인 개발은 제품의 사용성이나 조형성 개선에 주력하였으나 이제는 이에 더하여 사용자의 경험 전반에 무게를 두는 진전된 개념을 적용하도록 요구한다. 이를 위해 소비자의 가치체계에 대한 연구를 디자인의 중심적 지식기반으로 활용할 필요가 있으며 가장 핵심적인 내용의 하나가 경험 시스템에 대한 체계적 접근이다. 이런 배경에 따라 본 연구는 첫째, 제품디자인에 있어 '경험(experience)'의 개념을 소비자의 삶의 중요한 측면으로 새롭게 정의하고 두 번째, 경험디자인의 개념을 구체적으로 정의하며, 마지막으로 그 디자인 실무를 위한 적용체계 모형을 제시하고자 한다. 연구의 전개는 경험론(Empiricism)과 존 듀이(John Dewey)의 이론을 기반으로 경험개념을 밝혔고, 경험의 의미와 유형을 디자인 관점에서 재해석하였다. 이 과정에서 경험을 유발하는 구성인자를 도출하여 이를 디자인의 전개 체계와 적용 모형으로 설정하여 디자인에 활용 가능한 방법론이 되게 하였다. 제시된 적용 모형의 내용은 인간과 환경이 상호관계(interaction)하는 방식에 대해 디자인이 사용자에게 서로 다른 경험 유형과 요소를 제공함으로써 독특한 경험대상을 체득하게 하며 동시에 다양한 경험을 창출할 수 있는 모습을 보여준다. 경험디자인은 이와 같은 모형을 바탕으로 새롭게 창출될 수 있는 경험을 사용자 목표에 맞게 계획하고 설계하여 디자인에 적용함으로써 최적의 제품 경험을 사용자에게 제공하는 것이라 할 수 있다.

This Study starts from a recognition that the architecture is based on the process demanded by substantial needs as well as pure theoretical logic system. So this study aims at proposing another point of view differentiating process and principle of architecture from pure theoretical logic system in the creative process of the Governor's Palace by analyzing drawings in chronological order. Even though the Governor's Palace had not been built because of discord between authorities of India and Le Corbusier, it is undoubtedly one of the best proposals which contains very concepts and ideas of later Le Corbusier's architectural intentions. In the first design stage, overall conception of the building was carried out in the sketches and drawings till Jan, 1954 and in the second stage, the elaboration of the project was pursued till Mar. 1995. The scheme tends to begin too large and general in character, becoming tighter and more complex under pressure from the client and adjustments required by the design process itself. For example, scale reduction, division and development of internal circulation system and applying his early 'Five Points'. So new solutions are searched by oscillating between compromise modifications and radically different solutions in contracting the first ideas. From all these, it is concluded that the early doctrine (Five Points) are adjusted and extended towards another stage by the use of restricted pilotis, the concept of fenetre en longueur transformed into a sub stricture of facade, sustained concept of le plan libre, les toits jardins extended towards concept of the urban area. And these formal intentions of the Governor's Place has been carried through other contemporary projects like Mill Owner's Association in 1954 and Villa Shodan in 1952.

This study have goal with conceptual design for Offshore Structures of high pressure control valve for localization. Ball valve for development accomplished with flow analysis based on provision of ANSI B16.34, ANSI B16.10, ANSI B16.25 In order to localize the Offshore Structures high pressure control valve. Numerical simulation using CFD (Computational Fluid Dynamic) in order to predict a mass flow rate and a flow coefficient form flow dynamic point of view. The working fluid assumed the glycerin (C3H8O3). The valve inlet and outlet setup a pressure boundary condition. The outlet pressure was fixed by atmospheric pressure and calculated until increasing 1bar to 10bar. CFD analysis used STAR-CCM+ which is commercial code and Governing equations were calculated by moving mesh which is rotated 90 degrees when ball valve operated opening and closing in 1 degree interval. The result shows change of mass flow rate according to opening and closing angle of valve, Flow decrease observed open valve that equal percentage flow paten which is general inclination of ball valve. Relation with flow and flow coefficient can not be proportional according to inlet pressure when compare with mass flow rate. Because flow coefficient have influence in flow and pressure difference. Namely, flow can be change even if it has same Cv value. The structural analysis used ANSYS which is a commercial code. Stress analysis result of internal pressure in valve showed lower than yield strength. This is expect to need more detail design and verification for stem and seat structure.

In order to analyze the hydrogen distribution during a severe accident in the APR1400 containment, GASFLOW II was used. For the APR1400 NPP, a hydrogen mitigation system is considered from the design stage, but a fully time-dependent, three-dimensional analysis has not been performed yet. In this study GASFLOW code II is used for the three-dimensional analysis. The first step to analysis involving hydrogen behavior in a full containment with the GASLOW code is to generate a realistic geometry model, which includes nodalization and modeling of the internal structures such as walls, ceilings and equipment. Geometry modeling of the APR1400 is conducted using GUI program by overlapping the containment cut drawings in a graphical file format on the mesh view. The total number of mesh cells generated is 49,476. And the calculated free volume of the APR1400 containment by GASFLOW is almost the same as the value from the GOTHIC modeling. A hypothetical SB-LOCA scenario beyond design base accident was selected to analyze the hydrogen behavior with the hydrogen mitigation system. The source of hydrogen and steam for the GASFLOW II analysis is obtained from a MAAP calculation. Combustion pressure and temperature load possibilities within the compartments used in the GOTHIC analysis are studied based on the Sigma-Lambda criteria. Finally the effectiveness of HMS installed in the APR1400 containment is evaluated from the point of severe accident management
