As a form of media diversified and changed by the development of technology, fashion advertisements have brought a new change in representation of the body. With this transition, the characteristics of the body, which is in an inseparable relationship with fashion, have been dramatically changed in fashion advertisements. In hugely extended media flow, fashion advertisements suggest concepts of the body that are completely different from the past and became the focus in advertisements. Moreover, the body in fashion advertisements involve the symbolisms of social and cultural backgrounds followed by their commercialization. This study analyzes the characteristics of the body in fashion advertisements drawing on the innovative concepts of the body in contemporary society which is essentially different from the past ones; these characteristics are examined as postmodern features. The features are categorized as follows; hyperreal body, virtual body, fragmentization of the body through neologism, reconsideration of naked body, and decentralized body. The postmodern characteristics of the body have changed the boundary, broken traditional concepts and thoughts, and proposed new trends by creating revolutions though diversified media. Rapidly changing media is considered to be further accelerated; this transition highlights the postmodern characteristics of the body in fashion advertisements in more innovative methods.

After the publication of the competitive advantage of nations by Porter in 1990, the competitiveness of regional concentrations of industries has been often explained by the cluster concept. There are many definitions of clusters, but they mainly boil down to a geographically proximate group of interconnected companies and associated institutions in a particular field, linked by commonalities and complementarities. The shipbuilding industry in Korea can for sure be regarded as a competitive industry, as the spectacular rise of its world market share from 2% in the early 1970s to the current 38% impressively testifies, but can it be considered a cluster? Based on an analytical framework consisting of a typology of clusters and a context-sensitive evolutionary approach, the paper will show that over the last thirty years Korea's shipbuilding developed from a mere number of isolated, large shipyards (cathedrals in the desert) established by large conglomerates (chaebol) in close collaboration with the central government into an innovative cluster. The cluster is on the one hand characterised by a strongly developed supply industry and specialised universities and research institutes, but on the other hand by a weak, yet increasing role for local and regional institutions The specific and context-dependent characteristics of this innovative cluster are more important explanations for its competitiveness than the financial interventions by the central government, which are repeatedly put forward by European policy-makers in their trade war with Korea.

The pressure drop of a moisture separator in a steam generator is the important design parameter to ensure the successful performance of a nuclear power plant. The moisture separators have a wide range of operating conditions based on the arrangement of them. The prediction of the pressure drop in a moisture separator is challenging due to the complexity of the multi-dimensional two-phase vortex flow. In this study, the moisture separator test facility using the air/water two-phase flow was used to predict the pressure drop of a moisture separator in a Korean OPR-1000 reactor. The prototypical steam/water two-phase flow conditions in a steam generator were simulated as air/water two-phase flow conditions by preserving the centrifugal force and vapor quality. A series of experiments were carried out to investigate the effect of hydraulic characteristics such as the quality and liquid mass flux on the two-phase pressure drop. A new prediction model based on the scaling law was suggested and validated experimentally using the full and half scale of separators. The suggested prediction model showed good agreement with the steam/water experimental results, and it can be extended to predict the steam/water two-phase pressure drop for moisture separators.

Purpose The purpose of this research is to investigate the effect of social capitals on organizational knowledge sharing characteristics and individual innovation activities in community of practice (CoP) of manufacturing company. Design/methodology/approach For this purpose, we divide social capitals as three dimensions, i.e. structural, relational, and cognitive dimension. Structural dimension also consists of closure and Brokerage. Relational social capital is defined as trust about colleagues, superior authorities, and organization. Then, cognitive social capital is defined as a shared understanding among individuals, such as a shared language and codes within CoP. Knowledge Sharing is defined as quantity and quality of shared knowledge. We also defines the cause and effect relationships among social capitals, organizational knowledge sharing characteristics, and individual innovation activities in CoP of manufacturing company as follows. The social capitals will have positive effects on quality of shared knowledge. Then the quality of shared knowledge will have positive effects on the individual innovation activities. This paper tested the validity of these hypothesized casual effects and the sub-hypothesized causal relationships. For the purpose, we used the Partial Least Squares (PLS) for analyzing the causal relationships. Findings Our empirical results show that social capitals of CoP mostly have effects on organizational knowledge sharing characteristics (quantity and quality of shared knowledge) and knowledge sharing activities also have effects on individual innovative activities in the workplace. In this study, these result have a significant implication that a private company will be able to gain organizational innovative performance much better by strengthening CoP supporting activities.

This study introduces the Reliability-Based Design Optimization (RBDO) to enhance the kinematic and compliance (K & C) characteristics of automotive suspension system. In previous studies, the deterministic optimization has been performed to enhance the K & C characteristics. Unfortunately, uncertainties in the real world have not been considered in the deterministic optimization. In the design of suspension system, design variables with the uncertainties, such as the bushing stiffness, have a great influence on the variation of the suspension performances. There is a need to quantify these uncertainties and to apply the RBDO to obtain the design, satisfying the target reliability level. In this research, design variables including uncertainties are dealt as random variables and reliability of the suspension performances, which are related the K & C characteristics, are quantified and the RBDO is performed. The RBD-optimum is compared with the deterministic optimum to verify the enhancement in reliability. Thus, the reliability of the suspension performances is estimated and the RBD-optimum, satisfying the target reliability level, is determined.

본 연구는 기업규모와 전유성 등의 기술전략이 기업 혁신활동을 결정짓는 데 대한 영향을 실증적으로 분석해보았다. 한국기술혁신조사(KIS)의 2016년 2,003개 제조업체의 자료로 로짓회귀모형과 영과잉음이항회귀를 활용하였다. R&D 지출과 특허출원이 혁신활동의 성과를 나타내는 변수로서 이용되었다. 설명변수로서는 기업의 특성을 나타내는 기업 나이, 기술수준별 산업구분, R&D 종사자수, 벤처기업여부, 수출여부, 그리고 산업 전유 특성을 타나내는 네트워크, 전유방법, Spillover를 설정하였다. 우선, 실증적인 분석결과는 전반적으로 기업의 규모에 따라 혁신활동 결정요인이 다르게 나타남을 보여주고 있다. 더욱이 혁신활동을 결정짓는 데에, 중소기업은 대기업보다 산업의 특성에 의해 유의미하게 영향을 받았다. 규모가 작은 신생기업, 벤처기업, 혹은 수도권 소재기업일 때 혁신활동에 긍정적인 것으로 나타났다. 반면, 전략적 전유는 소기업 R&D 지출과 중기업의 특허출원 성과에 부정적인 영향을 미치고 있다. 다른 기업 또는 산업 간의 네트워크는 대기업을 제외한 기업들에서 혁신활동을 결정짓는 중요한 결정요인으로 나타나고 있다. 기업간의 기술적 상호작용은 기술 spillover과 혁신활동의 가능성을 높일 수 있으나, 이 성과는 기업 규모와 산업 특성에 따라 다르게 나타날 수 있음을 보여준다.
