제 4차 산업혁명 시대에 필요한 핵심 역량 중의 하나로 디지털 역량에 대한 관심과 그 중요성이 점점 커지고 있다. 디지털 역량은 디지털 사회에서 주어진 문제를 해결하기 위해 다른 사람과의 협업과 소통을 통해 디지털 기술을 활용하여 필요한 정보를 탐색하고 분석하여 결과물을 생산하는 능력을 의미한다. 디지털 역량은 기술의 발전으로 인해 새롭게 요구되는 지식과 능력들이 요구되는데 최근에는 컴퓨팅 사고력을 포함시키려는 시도들이 있다. 본 연구에서는 제 4차 산업혁명의 시대에 요구되는 디지털 역량으로 어떤 요소들이 포함되어야 하는지 고찰하고자 한다. 이를 위해 국내외 디지털 리터러시에 관한 관련연구 분석을 통해 중요하게 고려되고 있는 요소들을 체계적으로 분류하고 이를 기반으로 하여 국내 현실에 맞는 디지털 역량 모델을 제안한다. 디지털 역량 모델을 설계하기 위해 먼저, 디지털 역량의 조작적 정의와 함께 세부 요소들을 정의한 후, 전문가들의 의견을 통해 수정 보완하였다.

이 연구는 최근 빈번하게 언급되고 있는 제4차 산업혁명 관련 요소 기술들의 고용영향에 대한 논의를 정리하고 탐색적 연구를 수행하고자 하였다. 이를 위해, 먼저 2015년 9월 세계경제포럼(WEF)의 Global Agenda Council에서의 ICT 분야 경영진과 전문가를 대상으로 시행한 실현 가능성에 대한 설문조사 내용을 분석하고 확장하였다. 이를 바탕으로 국내 조직 종사자나 전문가를 대상으로 요소 기술들의 실현가능성뿐만 아니라 고용 영향에 대한 실증조사를 수행하였다. 실현가능성에대한 23개 항목별로 2025년에 실현가능한가에 대해 응답자들(n=169)은 전반적으로 긍정적으로 반응하였다. 또한 고용 영향 정도에 대해서는, 23개 항목별로 고용을 줄일 것이라는 항목이 많았지만 일부 요소기술 항목들은 고용을 늘릴 것으로 예상되었다. 향후 제4차 산업혁명의 고용영향에 대한 실증연구의 단초를 제공한다는 점에서 연구의 의의를 찾을 수 있다.

In the 1970s, the term Post - Modernism came into use to lable work of graphic design who broke up the Swiss style that had defined clarity and order. The characteristics of Post - Modernism graphic design include pluralistic and eclectic style. Those innovation of graphic design concerned with our social, political. cultural, and econonic changes. Deconstruction is one of the theory of Post-structualism. Deconstruction refers to the breaking down of metaphysics, rationalism, totality and so on. Deconstructive graphic design destroys traditional harmony even more than Marinetti's claim. Totality in graphic design seems to be ignored. Post - Modernism in architecture appears as historical revivalism and pluralism. The eclectic revivals and eccentric reinventions in graphic design are far too pluralistic and diverse to fit such as a simplistic system of style. Another innovation in graphic design occurs by electronic revolution. The impact of computer upon graphic design is becoming even more pronounced. Most importantly, Post-Modernism can consider the rediscovered freedom in graphic design. Graphic design is undergoing profound changes. But the essence of graphic design as com$$\mu$ication tools will remain unchanged.

In this study, the optimum design process of an indoor package air-conditioner (PAC) was implemented by Taguchi method. The goal of this study is to obtain the best set condition of each control factor composing of an indoor PAC. The number of revolution of a double inlet sirocco fan installed in an indoor PAC was measured by the orthogonal array of $L_{18}(2^3{\times}3^4)$ and analysed by using the-smaller- the-better characteristic among the static characteristic analyses. As a result, the optimum condition of an indoor PAC was found as a set of when the cost of production, assembling and working conditions were considered. Moreover, the number of revolution of a double-inlet sirocco fan used for an optimum condition was reduced about 8.5% more than that of a standard condition for the target flowrate of $18.5m^3/min$.

Significant findings concerning the cause of the gardening revolution of the eighteenth century in England, its landscape style and contribution to a new style are concluded as follows: 1. The English landscape garden is regarded as a great revolution in the history of landscape architecture, and it was in the eighteenth century, in England, that garden and landscape first came together. 2. For at no time in history has there been such general interest in gardens and in the total physical landscape, so much writing and criticism and open debate. 3. Garden design did not become a definite art form in England until the eighteenth century. During the period it can be seen that there were developing three distinct types of garden, that is, the picturesque garden, the 'poetic' garden and 'abstract' garden. 4. Also developing was a new appreciation for natural forms and natural landscape, expressed in painting, poetry and garden design, and the landscape gardeners tried bard to malce country scenery look as though man had not had a hand in it. Eventually these open spaces contributed to a new type of spatial form development of naturalistic landscape style which is today taken for granted as a normal component of the landscape architect's palette.

The aspheric lens has become the most popular optical component used in various optical devices such as digital cameras, pick-up lenses, printers, copiers etc. Using aspheric lenses not only miniaturizes and reduces the weight of products, but also lower prices and higher field angles can be realized. Additionally, plastic lenses are being changed to glass lenses more recently because of low accuracy, low acid-resistance and low thermal-resistance in the plastic lenses. Currently, one fabrication method of glass lenses is using a glass-mold method with a high precision mold core for mass production. In this paper, DOE (Design Of Experiments) and compensation machining were adopted to improve the surface roughness and the form accuracy of the mold core. The DOE has been done in order to discover the optimal grinding conditions which minimize the surface roughness with factors such as work spindle revolution, turbine spindle revolution, federate and cutting depth. And the compensation machining is used to generate high form accuracy of the mold core. From various experiments and analyses, we could obtain the best surface roughness 5 nm in Ra, form accuracy $0.167\;{\mu}m$ in PV.

The structural feasibility of a variety of non-conventional sludge digesters, in the form of thin shells of revolution constructed in concrete, has formed the subject of investigation of a recent programme of research at the University of Cape Town. Such forms are usually known in the literature as "egg-shaped", and the advantages of these over conventional digesters of the wide-cylindrical type are now well-recognised: superior mixing efficiency, less accumulation of deposits at the bottom, easier removal of bottom deposits and surface crust, reduced heat losses, and so forth. With the aim of exploring the structural feasibility of various non-conventional forms for concrete sludge digesters, and making available usable analytical data and practical guidelines for the design of such thin shell structures, a number of theoretical studies have recently been undertaken, and these have covered conical assemblies, spherical assemblies and parabolic ogival configurations. The purpose of the present paper is to bring together the different analytical approaches employed in each of these studies, summarise the main findings in each case, draw comparisons among the various studied configurations with regard to structural efficiency and functional suitability, and make appropriate conclusions and recommendations.

Smart Factory is a part of and a key point of the 4th industrial revolution. It performs optimization from the whole viewpoint, using comprehensive data of the post-process data by utilizing various sensors, controllers, and mobile devices beyond the existing factory automation level. In this paper, we design and implement an IoT platform that can detect the safety factors of the workers, the environmental factors of the factory, and real time monitoring at the control center, among the fields to implement smart factory. To accomplish this, we construct a monitoring device that provides sensor information control, server transmission of sensor information, and visualization of collected information. By using this system, it is possible to maintain the temperature and humidity for the optimum working environment in the factory. and also, By using the beacon, it is possible to measure the working time of the worker and trace the position.
