  • Genetic Algorithms are optimization algorithm that mimics biological evolution to solve optimization problems. Genetic algorithms provide an alternative to traditional optimization techniques by using directed random searches to locate optimal solutions in complex fitness landscapes. Hybrid genetic algorithm that is combined with local search called learning can sustain the balance between exploration and exploitation. The genetic traits that each individual in the population learns through evolution are transferred back to the next generation, and when this learning is combined with genetic algorithm we can expect the improvement of the search speed. This paper proposes a genetic algorithm based Cellular Learning with accelerated learning capability for function optimization. Proposed Cellular Learning strategy is based on periodic and convergent behaviors in cellular automata, and on the theory of transmitting to offspring the knowledge and experience that organisms acquire in their lifetime. We compared the search efficiency of Cellular Learning strategy with those of Lamarckian and Baldwin Effect in hybrid genetic algorithm. We showed that the local improvement by cellular learning could enhance the global performance higher by evaluating their performance through the experiment of various test bed functions and also showed that proposed learning strategy could find out the better global optima than conventional method.

  • 전통 날염방식(Silk Screen)과 디지털날염(Digital Textile Printing)을 비교해보면, 디지털날염은 디자인에서부터 날염까지의 전공정을 완전히 디지털화함으로서 다양하게 디자인할 수 있고 미묘한 색감의 흐름을 표현할 수 있어서 자연스러운 이미지의 표현이 가능하다. 그러나 현재 디지털날염을 피혁이나 직물에 적용하기에는 프린팅속도가 느려서 생산성이 낮고 이미지 내구성(세탁, 승화, 일광, 및 마찰견뢰도)이 낮은 등 많은 단점을 가지고 있다. 또한 신발산업은 현재 중국이나 동남아시아 등 개발도상국의 등장으로 수출의 국제적 경쟁시대에 접어들면서 대량생산이나 획일적인 디자인으로부터 벗어나 고부가가치 상품을 생산해야하는 과제를 안게 되었다. 한편 가죽에 응용가능한 잉크는 크게 수성, 유성, 용제형과 자외선 경화형의 잉크가 있으며 자외선 경화형 잉크는 자외선을 이용하여 기존의 잉크의 단점을 보완한 것이다. 자외선 경화형 잉크는 자외선 램프를 열원으로 하여 이온 또는 라디칼 중합, 광중합을 하며, 에너지 소비가 적어 경제적이며 시스템 가동시 비활성 기체가 필요하지 않다. 또한 자외선 경화형 기술은 상온에서 이용할 수 있으며 잉크의 경우 건조하는 데 걸리는 시간이 필요하지 않다. 또한 시스템을 가동 시키거나 중지 시키는 것이 쉬우며 고속으로 연속적인 일을 처리할 수 있다. 프린터의 크기가 작아 공간 효율이 유리하며 용제나 $CO_2$가 발생하지 않아 친환경적인 기술이라 할 수 있다. 따라서 본 연구에서는 자외선 경화형 시스템을 잉크에 적용하여 피혁 표면에 프린팅한 다음 그 견뢰도를 측정함으로써 그 효과를 알아보았다. 세탁에 의한 Matlab 측정값으로부터 용제형 잉크의 경우는 세탁 전, 후 line width가 큰 차이를 보이나 자외선 경화형 잉크의 경우는 그 차이가 적음으로부터 자외선 경화형 잉크가 용제형에 비해 색상 탈리가 적었음을 말한다. 또한 raggedness값 역시 마찬가지 결과를 보여 안료 색소와 피혁의 접착성이 향상된 것을 알 수 있다. SEM을 이용한 피혁의 표면과 단면 사진을 보면 용제형보다 자외선 경화형 잉크를 사용한 피혁이 좀 더 매끈한 표면을 보이는데 이것은 접착기능을 하는 아크릴레이트에 의해 균일한 날염이 가능하기 때문이라 고 생각된다. 이상의 결과로부터 자외선 경화형 잉크가 세탁, 마찰, 일광 견뢰도가 우수함을 알 수 있었으며 기존의 용제형 잉크를 대체할 수 있는 좋은 재료라고 생각된다.

  • 'Waiting for a Thousand Years & Mingling with World People-Gangneung Danoje Festival 2017 as an Important Intangible Cultural Property' is the festival with the longest history in Korea. In spite of its historical value, however, there are not many academic researches on the value of festival brand equity. Thus, the objective of this study is to empirically analyze the influence relationship between selection attributes of festival storytelling, brand equity, brand attitude, and brand loyalty through the structural equation model. Regarding the spatial scope of thesis material, a survey was conducted focusing on 657 tourists visiting the Gangneung Danoje Festival. In the results of verifying the hypotheses in accordance with the structural equation model, the selection attributes of festival storytelling had effects on the brand equity, and the brand equity had effects on the brand attitude and brand loyalty while the brand attitude had effects on the brand loyalty. Based on such results of this study, the implications could be suggested as follows. First, the local contents culture should be developed together with local experts and residents by finding its local custom. Second, the brand equity that could prioritize the strategy of characteristics should be increased by emphasizing the selection attributes of storytelling. Third, the phased development should be achieved through local residents' open participation by dividing roles of experts and non-experts as festival manpower.

  • Quality of the library service, because it is based on the subjective meaning of the user for a particular service, depending on the individual expectation level, can be divided between satisfaction and dissatisfaction. Therefore, library services that are performed in public libraries also ultimately assessment of library services may influence based on the expected value of the user. This study is a satisfaction survey of library services to the public library of Goyang. Overall satisfaction of Public Library of Goyang in this study are in the following orders: 1) facility, 2) cultural programs and courses, 3) librarian kindness, 4) collections. To understand the specific meaning of each preference, it was analyzed in the followings: 1) the expectation level to the library space, 2) expectation level to librarians, 3) new service the users desire, 4) service the users want, etc. by age and occupation. As the age of the user increases, the demand for traditional library usage increased. In addition, services that utilize the same library external resources and utilization of external lecturer is like finding employment and art courses, expectation level of users such as reading course to utilize library resources was the highest.

  • The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

  • Vocal and instrument apprenticeship in applied music has been accepted without significant changes since the introduction of applied music education to South Korea. Few discussions or suggestions about other types of teaching than 'one-to-one lessons' or 'education of apprentices by assigned specialists' have been made. Since the introduction of applied music education to South Korea late in the 1980s, the CAI(Computer Aided Instruction) courseware development for applied music education has not actively been under way. The area of applied music has also made rapid progress in terms of music producing or music videos using computers. Actually, the improved computer program is not positively applied to applied music education. This study aimed to present learning methods using the improved functions of music production softwares to improve the traditional apprenticeship system in the area of vocal training in applied music. In particular, it used the technique of auto tune-pitch shift developed for interval correction in sound sources. By giving real-time feedbacks concerning intervals or monitors visually after recording, it intended to present a learning method to induce improvement in accuracy of intervals in vocal training. This study is expected to present a method that allows vocal trainers to overcome temporal and spatial limitations in applied music and make their vocal training more efficient.

  • Living spaces are the results of social environment and also the reflection of the viewpoints by their residents toward human culture and society. Therefore, in studying living spaces, the true essence of the spaces could be easily distorted when cultural and symbolic motives and values are disregarded and only their apparent characteristics are looked into. Hence, it's necessary to simultaneously understand both physical dwelling spaces from architecture's view points and social ideas, simultaneously, of people who form and interact with the spaces. Hence, this paper tries to study housing religion which is one of shamanistic religions which, in turn, have been the fundamental element of ancient religions and came into existence on the basis of dwelling spaces. This study presumes that house religion may have been permeated with its creators' ideas about living and those ideas could be one of those factors which plays a role in organizing of dwelling spaces. As such, with these prior analyses, this thesis attempts to understand the meaning of various dwelling spaces via the characteristics and functionalities of various house spirits which are mentioned in a local house religion and also will find out spatial harmony of Korean traditional living spaces by way of corelations among living spaces, people, and personalized house spirits. Almost all traditional Korean houses have assigned a house spirit to their individual dwelling space. This means a traditional house was considered as a scared space in a secular world called human society and the space was actually intended to protect sacredness of dwelling places from earthliness outside. So when the hierarchy of house spirits in housing religion is projected to a Korean traditional house, it can be shown that a dwelling house as a building was personified to a respectable human status. In other words, it can be concluded that each space was synonymous with a dwelling place for each house spirit and was considered a sacred godly place. In a nutshell, not only each space in a Korean traditional house was a physical and functional space, but also it formed a scared spatial place along with the concept of house spirits intending to ward off disasters and enjoy a comfortable life through those religious symbols and meanings. Housing shamanistic religion which has long been existing with residents and their lives is seeped with the viewpoints of the residents toward life, and hence understanding the meanings and organization of Korean traditional housing can reveal commonly practiced principles of spatial organization of the traditional houses. Therefore an analysis of Korean traditional housing on the basis of humanistic social ideas will help learn Korea's traditional houses which need to be understood in various methods.
