In order to make best use of NC machine tools with minimal labor costs, they need to be in operation 24 hours a day without being attended by human operators except for setup and tool changes. Thus, unattended machining is becoming a dream of every modern machine shop. However, without a proper mechanism for real-time monitoring of the machining processes, unattended machine could lead to a disaster. Investigated in this paper are ways to using PC camera as a real-time monitoring system for unattended NC milling operations. This study defined five machining states READY, NORMAL MACHINING, ABNORMAL MACHINING, COLLISION and END-OF-MACHINING and modeled them with DEVS (discrete event system) formalism. An image change detection algorithm has been developed to detect the table movements and a flame and smoke detection algorithm to detect unstable cutting process. Spindle on/off and cutting status could be successfully detected from the sound signals. Initial experimentation shows that the PC camera could be used as a reliable monitoring system for unattended NC machining.

실시간 시스템에서는 계산 결과의 논리적 정확성과 결과가 산출되는 시간의 정확성을 요구한다. 이러한 요구사항을 지원하기 위해 UCI Dream Lab에서 제안한 적시 서비스 능력을 보장하는 실시간 객체인 TMO 객체를 토대로 자동 코드 생성기의 설계를 제시한다. 기존의 모델 기반 개발방법론은 시스템을 추상화하고 그 모델을 상세화 과정을 거쳐 구현에 필요한 정보를 갖게 되고, 이를 바탕으로 자동으로 코드를 생성 할 수 있게 된다. 기존의 도구들은 표준 UML을 사용하고, 표준 UML은 시간 제약 조건을 기술하는 방법을 제공하지 않기 때문에 이에 따라 개발된 실시간 시스템 코드 자동 생성기는 완전한 코드를 생성하지 못한다. 본 논문에서는 실시간 시스템 개발에 모델 기반 개발방법론을 적용하기 위해 TMO객체를 이용하여 기존 UML 모델의 구조 모델과 행위 모델에 실시간 특성을 추가해 확장하고 확장된 모델을 토대로 자동 코드 생성기의 설계를 제안한다.

A circular bark with a 30 cm width was artificially removed from the trunk of a 250-year-old zelkova tree (Zelkova serrata) heavily damaged by artificial girdling in Sunchang, Jeonbuk Province in March of 2005. The debarked area was cleaned approximately 10 days after artificial girdling and bark margins with 2 cm width above and below the girdled portion were cut off to promote wound callus formation. Nine pieces of fresh bark (width 8 cm, length 35 cm, thickness 0.5 cm) were then prepared from branches of neighbor zelkova trees broken by heavy snowfalls and pasted onto the girdled portion of the tree, after which a Vaseline dressing was applied to water-proof the area and rubber bars were used to hold the implants to the trunk. Two pieces of the implanted fresh barks were successfully grafted onto the girdled area and the damaged tree has been vigorously growing over 13 years. To our knowledge, this is the first case of successful bark implantation to cure a 250-year-old zelkova tree heavily damaged by artificial girdling. This bark implantation technique will be utilized for the conversation and management of heavily damaged big and old trees in the future.

Modern society has become an aging society, and the National Statistics Office(NSO) expects that Korea will be also an aging society by 2019, that is, people over the age of 65 will account for 14 percent from the total population. In addition, the increase of labor flexibility is also one of the dramatic features in modern society. However, this social shift have unpredictable results, that is, the advent and increase of grandparent and grandchildren family. Modern medical technology has given Koreans longer expectancies, and structural and economic changes in society have brought early retirement. One of the main reasons that grandparent and grandchildren family increase is below an average of two children per family. There are various services available such as Health support center, Dream start center, Youth support center, Community child center, and Community welfare center. Besides, schools operates various programs for grandparent and grandchildren family with social workers and school counselors. But, most of all, what is necessary is a change of perspective on them. Basically, we need to develop a clear perspective on grandparent and grandchildren family as a not dismantling family type but alternative family type with creating a separate program or service

The successful mass media drama, 'The 1st Shop of Coffee Prince', has received lots of supports from the audience by showing them a vivid life and also enabling them to dream a real fantasy. One among the most powerful strategies that made this drama stay successful is the marketing value of the drama space fully maximized when doing the production. This study, introducing a unique representation of 2-D cell matrix with x-y plots of drama space set along the time stream following the scenario, first proposes a quantitative way of uncovering the hidden relation between drama space and scenario using nonlinear matrix filtering method and, secondly, suggests possible service designs mainly constrained by economical standpoints of the stakeholder in producing the drama. The methodology may invoke a plausible contradiction with art instincts that have hardly been supposed to be affected by financial debate, which, nevertheless, must sometimes be allowed under the circumstance of pursuing optimality in programming and producing the drama that must survive in the world of competitive market of service business.

Surrealism, appeared in the beginning of the 20th century and affected almost all art fields, is one of the most representative art trends. Surrealism, not restricted from any rules and traditions but tried to produce a new appreciations in the world of dream and unconsciousness, also has affected fashion. In this paper, I have tried to find out how the surrealism has been expressed in the modern fashion, especially in Thierry Mugller's design. Thierry Mugler is one of the most famous designers who have expressed surrealism in their fashion designs. I have classified his designs and researched them by the application into the human body and the nature, by the metaphor and transformation of things, and by the metamorphosis of location and an optical illusion. It was based on Depaysement which is one of the ways in surrealistic expressions. The result of the study is followings; First, surrealism made fashion design possible to creat unlimitedly and sublimated it anew modern beauty by attempting the varieties of the fashion, not restricted from any rules and traditions. Second, surrealism made the general public to complete anew recognition and valuation about fashion by expressing the external character and the internal meaning on the clothes. Third, surrealism made people to recognize, which clothes is not simply wearing thing but also one of the art expression forms.

The contemporary South Korean landscape is characterised by a massive display of modern apartment buildings. They are omnipresent in their monotonous manifestation and represent the dream of the Korean population. Serial mass housing is a typology that has had a great diffusion all over the world, but how has modern housing developed in South Korea? To this end, what are the resulting local adaptations?. This paper retraces these key evolutional aspects. Methodologically, it draws on a scholarly literature review as well as on-site photographic surveys, developed in connection with an educational program at the Korea Tech University. The result is the analysis of both the urban and architectural transformation from the early modernisation period to the present condition of contemporary housing. A historical background introduces Korean traditional urban houses, to be used as a context to describe the contemporary modern city that has developed since the 1960s. The main emphasis is then placed on the urbanisation process that fully matured during the 1980s together with a focus on the mass housing typology as the main pivot in the urban transformation. Finally, the paper will draw a parallel between modern Western theories and Korean applications.

Some innovative researchers have had a dream of self-thinking intelligent computer. Alphago, at last, showed its possibility. With it, most computer engineers including even students can learn easily how to do it. As the interest to the deep learning has been growing, people's expectation is also naturally growing. In this research, we tried to enhance the game ability of a 7-poker system by applying machine learning techniques. In addition, we also tried to apply emotion analysis of a player to trace ones emotional changes. Methods and outcomes are to be explained in this paper.

Perhaps nothing more vividly illustrates the many different ways in which traditions can be interpreted than a study of the life of Confucius in modern times. In China and Korea, Confucian values and culture are dismissed and scorned during some periods and held up as facilitators of cultural prosperity in others. This changing perception of and attitude toward the Confucian tradition in modern society embodies the long life of the Confucian tradition and its continually evolving trajectory, as well as its versatility within shifting sociopolitical milieux spanning distance and time. In this paper, I investigate the (re)emergence of Confucius in modern Korea and China with a comparative and critical gaze. I demonstrate how different modern interpretations of Confucius, both negative and positive, in these two countries bring new life to the Confucian tradition within their own complex social realities. By focusing on the recent revival of Confucius in China-Anti-tradition of Korean dramas, the Restoration of Confucian Culture in China and Korean Wave, the modernity of China in Confucius are examined, and finally, in terms of the means of realization of the Chinese dream-I illuminate how the image of Confucius serves the (re-)invention of contemporary China, with her pervasive desire to romanticize and materialize China's past as well as her future.
