As one of the key competencies required in the era of the Fourth Industrial Revolution, interest and importance of digital competency is the growing. Digital competency means the ability to search and analyze necessary information using digital technology through collaboration and communication with other people to solve problems given in digital society and to produce the result. In this study, we will consider what factors should be included in the digital competence required in the era of the Fourth Industrial Revolution. To do this, we systematically classify factors that are considered to be important through analysis of relevant research on domestic and foreign digital literacy, and propose a digital competence model suitable for domestic reality based on this classification. In order to design a digital competence model, we first define the operational factors of the digital competence and then define and refine it by experts.

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.

This study aims to look at the application methods of landscape architecture in response to the 4th Industrial Revolution. The results of the analysis of trends in the 4th Industrial Revolution and the subsequent search for application methods to the field of landscape architecture are as follows. First, the 4th Industrial Revolution means innovative change based on digital technology and seeks to create value based on intelligent information technology, and continuous growth is being made through innovation. This requires expertise to collect large amounts of information and creatively rework it, and a strategy to flexibly cope with changes in the times. Second, the status of technological use in response to the 4th Industrial Revolution in the field of landscape architecture is generalizing the establishment of precise analysis results such as survey technology and global mapping using drones, three-dimensional design simulation, and VR. In the field of traditional landscape architecture, efforts are made to obtain accurate fact-finding data on landscape site components. Third, the application methods in the field of landscape science according to the 4th Industrial Revolution in the future are required to supply precision technology and supply programs in the technology sector, and to provide a shared platform. In addition, a systemically standardized process will need to be established for this. In addition, educational efforts should be continued to professional manpower training and provide economic support for the development of technologies.

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.
