본 논문은 다관절 붐의 선단이 구조물과 충돌할 때 발생하는 각 붐의 동응력에 대해서 논하고자 한다. CATIA를 이용하여 3D 모델을 작성하고, ADAMS와 ANSYS를 이용하여 메쉬작업을 수행 후 응력데이터를 포함한 다관절 붐의 MNF를 만든다. 이 두가지 모델을 가지고 ADAMS에서 FFT해석을 수행하여 각각 모델의 타당성을 알아본다. ADAMS에서 타당성이 검증된 모델을 이용하여 붐 선단의 충돌해석에 따른 동특성 해석을 수행한다. ADAMS Durability를 이용하여 다관절 붐과 구조물의 충돌시 각 붐에 응력이 크게 발생하는 지점을 알아보고자 한다.

인터넷의 발전과 정보기술의 도입으로 음반회사의 비즈니스 환경은 급속도로 변화하였다. 소비자의 역할은 단순히 콘텐츠를 소비하는 것을 넘어, 적극적으로 콘텐츠 창출에도 기여하는 공동의 창조자 (co-creator) 역할로 확장되었다. 본 연구에서는 기존의 연구가 밝히지 않았던 음반회사와 소비자의 관계변화에 초점을 맞추어, 소비자들이 어떻게 가치창출에 영향을 주고 음반회사는 어떻게 대응하는지를 분석하였고, 본 연구의 결과는 이론적인 공헌과 함께 실무적으로도 의미 있는 인사이트를 도출하고 있다.

This paper or article is about bamboo products from Damyang that have been degenerated by the threat of Chinese low-cost products. Comparing the products from Damyang and China, we could point out four problems and come up with solutions. Firstly, we need strong and specific storytelling based on historical facts and various research to boost the bamboo industry. In order to introduce interesting storytelling to the public, it is also necessary to train some good-quality workers. The public would be more familiar with the bamboo products from Damyang than Chinese products. Secondly, technologies used for bamboo products from Damyang are extremely behind the times. Skill shortages for bamboo products caused to create unattractive products to the public for approximately 30 years. Thus, we need to acquire advanced technologies from abroad as well as to develop our own. Thirdly, Even though attractive bamboo products would be produced with advanced technologies, workers in bamboo industry lack knowledge of distribution channels and marketing strategy so that there is no way to introduce their products effectively to the consumers. Therefore, government agencies or marketers should educate workers to help running their business successfully. Finally, bamboo products have been fashion and living items for some specific consumers for the last years. However, we need to create variously new types of bamboo products through the collaboration with a wide range of artists to be widely appealing. In conclusion, it is important to be aware of the problems and solutions above. The 17th Bamboo Expo in Damyang will be a great opportunity to introduce Korean bamboo products in worldwide and develop the bamboo industry.

A study of the comparison of customers' satisfaction and loyalty at McDonald's two types of outlets is presented. The objective of this study is to test correlation among selection attributes, customer satisfaction and loyalty of customers patronizing two types of Mcdonald's restaurants - stand alone and co-branded, as Mcdonald's is known to be actively participating in co-branding with discount stores such as E-Mart. In order to measure customer loyalty, benchmark scores from customers showing extreme satisfaction are compared to the mean scores of total sample customers at each outlet. Meeting or exceeding benchmarking scores does not automatically bring in and create loyal customers but in doing so will certainly help build up strong customer relationship which will create additional loyalty. Marketers should be well aware that statistically significant difference do exist between these two groups of customers and should take into consideration these findings in opening up new outlets or renovating existing outlets.

When listening the various speech synthesis systems developed and being used in our country, we find that though the quality of these systems has improved, they lack naturalness. Moreover, since the voice color of these systems are limited to only one recorded speech DB, it is necessary to record another speech DB to create different voice colors. 'Voice Color' is an abstract concept that characterizes voice personality. So speech synthesis systems need a voice color control function to create various voices. The aim of this study is to examine several factors of voice color control rules for the text-to-speech system which makes natural and various voice types for the sounding of synthetic speech. In order to find such rules from natural speech, glottal source parameters and frequency characteristics of the vocal tract for several voice colors have been studied. In this paper voice colors were catalogued as: deep, sonorous, thick, soft, harsh, high tone, shrill, and weak. For the voice source model, the LF-model was used and for the frequency characteristics of vocal tract, the formant frequencies, bandwidths, and amplitudes were used. These acoustic parameters were tested through multiple regression analysis to achieve the general relation between these parameters and voice colors.

개념 계층은 지식을 그룹화하여 다단계로 표현하며, 이는 자료의 분류, 저장 및 검색을 효율적으로 지원해 준다. 일반적으로 도메인 전문가의 수작업을 통해 개념 계층이 생성되었으며, 이는 생성과 유지에 많은 비용이 소요되면서도 일관성 유지가 어려운 단점이 있다. 본 논문은 미리 정의된 상위어 관계를 이용하여 문자형 자료의 개념 계층을 자동으로 생성하는 방법에 대한 연구이다. 개념 계층의 자동 생성을 위해서는, 다중 의미로 사용되는 단어에서 적절한 의미를 찾아 내어 모호성을 제거해야 하며, 외부 정보를 이용하여 모호성이 제거된 단어를 그룹화하고 계층을 생성하는 작업이 필요하다. 우리는 워드넷 (WordNet)의 다중 의미에 대한 설명 및 상위어 관계를 이용하여 모호성을 제거하고 개념 계층을 생성하는 방법을 제안 한다.

In chemistry, the study of sonochemistry is concerned with understanding the effect of sonic waves and wave properties on chemical systems. In the area of chemical kinetics, it has been observed that ultrasound can greatly enhance chemical reactivity in a number of systems by as much as a million-fold. Nano-technology is a super microscopic technology in which structures of 100 nanometers or smaller can be investigated. This technology has been used to develop $TiO_2$ materials and $TiO_2$ devices of that size. Thus far, electrochemistry methods and photochemistry methods have generally been used to create $TiO_2$ nano-size particles. However, these methods are complicated and create pollutants as a by-product. In the present study, nano-scale silver particles (5 nm) were prepared in a sonochemistry method. Sonochemistry deals with mechanical energy that is provided by the collapse of cavitation bubbles that form in solutions during exposure to ultrasound. $TiO_2$ powders 25 nm in size doped with Ag were formed using an ultrasonic sound technique. The experimental results showed the high possibility of removing pollution through the action of a photocatalyst. This powder synthesis technique can be considered as an environmentally friendly powder-forming processing owing to its energy saving characteristics.

Recent advances in the media have no special change is the development of the 3D stereoscopic image, which started in the movie is coming over now to the broadcast. Confusing variety having, in the production of 3D images that are waiting for the standardized production. 3D images of them being used in broadcast subtitles, first because there is no standardized production systems, making it look is dedicated to the time and effort. This research necessary to create 3D images of these subtitles, titles, text-based objects, such as Rig imaging using a standardized way to synthesize the most stable is proposed. First, with captions or titles, and the readability and understanding of the uniqueness to the human eye to create an environment that is kind of crowd. Because of this, excessive camera Ferrell Rex (gap) created a branch bunch of snow, work should not hurt readability. 100 adult men and women throughout the experiment.

This research aims to evaluate the current state of technology of enterprises in Vietnam in comparison with several countries in the AEC economic community, thereby to propose several recommendations to Vietnamese enterprises in order able to promote technology innovation activities, create competitiveness with enterprises in the region. Qualitative research methods are used through statistics and comparative descriptions from data collected from various sources: WEF, World Bank, CIEM, General Statistic Office. The study results show that Vietnamese enterprises still have many limitations in technology, originated from their small business scale (capital and labor), the current research capacity is still low, the funding for this activity is not high and the accessibility of the capital is still difficult. According to the Global Competitiveness Index, Vietnam's science and technology indexes are low compared to other AEC-developed countries including the availability of the latest technology; the acquisition of technology at the enterprise level; the capacity of improvement; quality of scientific research organizations..., which shall be a major barrier for Vietnamese enterprises to have to overcome to be able to create the competitiveness when entering the global market. From then on, the authors proposed solutions for two subjects, enterprises and government, to help Vietnamese enterprises to overcome this barrier.
