The late 20th century saw the industrial period end only to transform into the digital era where people have begun to pay attention to craft because it a field that respects emotion as the essential value, an alternative to overcome the side effect that people have created. Today a new world - where the virtual and the real co-exist through artificial intelligence (AI) - has suddenly approached us and the future of craft is faced with a new situation as it needs to present a new creative solution as a tool that is necessary for human way of life - a tool that has been a necessity throughout history and the evolution of life. As a result for a continued development, craft attempts to establish a new paradigm through current trends represented by our modern society, which is the emergence of creative development through convergence. This study presents creative experiments attempted through the convergence of craft with other heterogeneous tendencies connected to the field. The objective of the study is to enable makers to acquire a more creative way of thinking at the same time as inspiring them and suggesting new creative possibilities in order to develop their work through creative convergence. In Chapter 2, the study investigates on the current status of craft in general, and compares it with what is taking place in Korea; in Chapter 3 the significance of convergence in craft and the process of creating is addressed through case studies. Lastly in Chapter 4, with the basis on analytical case studies, the attribute and the potential of convergence in the field of craft is observed. By analyzing different phenomena presented through attempts to converge in contemporary craft, it has been possible to view the future of the 21st century craft through assessments on what is active and what is as yet hidden potential.

The construction craft workers have been getting older and have become drained, in spite of the vital factor that it directly affects productivity and quality as a final producer. This situation in the construction industry is ultimately due to evasion of performances by young craft workers. Therefore, the aim of this study is to propose the certification and level system of construction craft workers and to extract young craft workers from the market for construction craft workers so as to supply and demand high quality of craft workers. First of all, the present status and problems of the domestic construction craft workers are considered in this study. Furthermore, the appropriate way to establish its certification and level system is suggested from the Interview with experts, as well as references of German and Australian case. The revitalization of certification and level system provided in this study is expected to ensure that the craft workers are not simple laborers, but are required the professional knowledge and skill. Besides, it will lead to strengthen specificity and to break from aging, by taking young and qualified craft workers into the construction industry. Also, it will promote an employment stability by connecting the social security system.

This study was performed to investigate the effect of light quality on evapotranspiration and graft-taking characteristics of watermelon grafted seedlings using blue, red and far-red light-emitting diodes (LED). At initial stage of graft-taking, blue light increased the evapotranspiration rate (EVTR) of grafted seedlings as compared to effects of red and far-red on EVTR of grafted seedlings. Grafted seedlings graft-taken under red and blue LED showed the high graft-taking of 100% and 96%, respectively. However, grafted seedlings graft-taken under far-red LED showed the graft-taking of 80% and survival of 60% with low seedlings quality after hardening. The stem of grafted seedlings graft-taken under red light was elongated but blue light suppressed the stem elongation. The leaf area of grafted seedlings graft-taken under red light was increased. It is concluded that the effect of light quality using LED on graft-taking of watermelon grafted seedlings was significantly recognized. Considering the duration of quality of grafted seedlings graft-taken under artificial lighting, LED could be used as an effective lighting sources to validate the continuance of seedling quality.

In this study, lateral vibration analysis has been conducted on a propulsion and lift shafting system for an air cushion vehicle using ANSYS code. The shafting system is totally flexible multi-elements system including air propeller, aluminum alloy of lift fan and thin walled shaft with flexible coupling. The analysis included the lateral natural frequencies, mode shapes and harmonic analysis of the shafting system taking into account three-dimensional models for propulsion and lifting shaft system. In case of ACV the yawing and pitching rate of craft will be quite high. During yawing and pitching of craft significant gyroscopic moment will be applied to the shafting and will generate high amplitude of lateral vibration. So, such a shafting system has very intricate lateral vibrating characteristics and natural frequencies of shafting must be avoided in the range of operating revolution. The control of lateral vibration is included in this study.

Taking a look at art history around the world reveals the presence of ceramics in a wide range of areas. There have been many changes and developments over the years, but especially notable is the fact that in the course of history, the craft of ceramics has become an aesthetic art form rather than serving the original purpose of providing daily object of necessity. The Art Nouveau movement had peat influence in the development of ceramics before and after 19$^{th}$ century, and its inherent style continues to be copied and produced to modem day. The Art Nouveau style can today be seen particularly in contemporary tableware designs reflecting its graceful motifs that are now richly presenting themselves on table settings. This study looks at the possibilites of Art Nouveau in ceramics, namely by combining both traditional formativ qualities and contemporary visual inspirations to seek new expressions of beauty. In order to document records and analyze formative developments of Art Nouveau, representative pieces have been chronologically presented to cover the period from 1895 to the present.
