As the competition becomes more severe, the importance of brand confidence is coming to the front mainly because there has been a tendency of the customer for choosing a product or service in conjunction with the confidence. The concept of brand personality has formed as a result of various efforts for establishing a differentiated and confident brand image. The brand personality is regarded a useful mean for meeting objectives of a corporation for establishing a distinctive brand identity as well as customers for expressing their self-image. In line with the growing importance of the brand personality, researchers have attempted to measure it by various methods. However, most of researches were based on verbal and quantitative methods which take a long period of time and lots of efforts to analyze their results. Such methods also have limitations for visualizing the results. In this vein, this study aims to develop a new visible brand personality measurement system by utilizing the purpose-designed avatar. Major findings of the study are as follows: Firstly, the avatar can be an effective mean for visualizing the brand personality. As the avatar can visualize the personalities of human-beings through facial expressions, clothing, attitudes and movements, a specially designed avatar can express the brand personality. Secondly, types of the brand personality can be segregated into distinctive seven classes and such classes are used as guidelines for developing specially designed brand personality avatars. Thirdly, the purpose-designed brand personality avatar can be an effective mean for measuring the brand personality as a result of various tests for the validity. In condusion, avatar can be a more powerful tool than language for measuring the brand personality.

DNA 컴퓨팅은 분자 수준(molecular level)에서 연산을 수행한다. 따라서 일반적인 실리콘 기반의 컴퓨터에서와는 달리, 순차적인 연산 제어를 보장하기 어렵다는 특징이 있다. 그러나 DNA 컴퓨팅은 화학반응에 기초한 연산이기 때문에, 실험자가 의도한 연산을 많은 수의 분자에 동시에 적용할 수 있으므로 실리콘 기반의 컴퓨터와는 비교할 수 없는 병렬 연산을 구현할 수 있다. 병렬 연산을 구현하고자 할 때, 일반적으로 연산에 사용하는 모든 DNA 분자들을 대상으로 연산을 구현할 수도 있다. 그러나 전체가 아닌 일부의 분자들을 상대로 연산을 수행하는 것 역시 가능하며 이 때 자연스러운 방법으로 사용할 수 있는 방법이 배깅(Bagging)이나 부스팅(Boosting)과 같은 앙상블(ensemble) 계열의 학습 방법이다. 일반적인 부스팅과 달리 가중치를 부여하는 것이 아니라 특정 학습자(learner)를 나타내는 분자들을 증폭한다면 가중치를 분자의 양으로 표현하는 것이 가능하므로 분자 수준에서 앙상블 계열의 학습을 구현하는 것이 가능하다. 본 논문에서는 앙상블 계열의 학습 방법 중 특히 부스팅의 효과를 DNA 컴퓨팅에 응용하고자 할 때, 어떤 방법이 가능하며, 표현 과정에서 고려해야 할 사항은 어떠한 것들이 있는지 고려하고자 한다. 본 논문에서는 규모를 사전에 한정할 수 없는 진화 가능한 그래프 구조(evolutionary graph structure)를 학습할 수 있는 방법을 찾아보고자 한다. 진화 가능한 그래프 구조는 기존의 DNA 컴퓨팅 방법으로는 학습할 수 없는 문제이다. 그러나 조합 가능한 수를 사전에 정의할 수 없기 때문에 분자의 수에 상관없이 동일한 연산 시간에 문제를 해결할 수 있는 DNA 컴퓨팅의 장정을 가장 잘 발휘할 수 있는 문제이기도 하다.개별 태스크의 특성에 따른 성능 조절과 태스크의 변화에 따른 빠른 반응을 자랑으로 한다. 본 논문에선 TIB 알고리즘을 리눅스 커널에 구현하여 성능을 평가하였고 그 결과 리눅스에서 사용되는 기존 인터벌 기반의 알고리즘들에 비해 좋은 전력 절감 효과를 얻을 수 있었다.과는 한식 외식업체들이 고객들의 재구매 의도를 높이기 위해서는 한식 외식업체의 서비스요인, 식음료요인, 이벤트 요인 등을 강화함으로써 전반적인 종사원 서비스 품질과 식음료품질을 높이는 전략을 취해야 한다는 것을 시사해주고 있다. 본 연구는 대구 경북소재 한식 외식업체만을 대상으로 하여 연구를 실시하여 연구의 일반화와 한식 외식업체를 이용하는 이용 고객들이 한식 외식업체를 재방문하는 재구매 의도가 발생하는데 있어 발생하는 과정을 설명하는 종단적 연구를 실시하지 못한 한계점을 가지고 있다.아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자인 기술개발 및 디자인 교육지원의 강화를 통하여 각각 디자인 경쟁력$\righta

최근에 정보 고속도로 사업계획과 관련하여 세계 여러나라들이 실시하거나 실시 예정인 VOD 시험서비스에 많은 관심이 일고 있다. VOD서비스와 같은 대화형 TV 서비스(I-TV, Interactive-TV Service)는 컴퓨터, 통신 가전업체 그리고 영화 제작사등이 함께 참여하고 있다. 본 기고에서는 차세대 통합 멀티미디어 사업이라는 대화형 TV서비스의 개요와 요소기술, 그리고 서비스의 동향 및 전망을 알아보기로 한다. 1. 대화형 TV 서비스(Interactive TV Service)의 개요 현재까지 대부분의 TV 시청자들은 방송국으로부터 송신되는 공중파나 CATV서비스를 통해 프로그램 서비스를 받아보는 방송(broadcasting)방식 형태의 서비스를 이용해 왔다. 그러나 이러한 일방적인 수신방식은 최근 미국의 클린턴 행정부가 미국의 차세대 기반 통신망 구축 정책(정보 고속도로 사업; Information Super High-way)의 일환으로, CATV 사업자뿐만 아니라 지역 전화회사까지도 참여하고 있는 VOD(Video On Demand) 시험서비스가 시행됨에 따라서 미국은 물론, 우리나라를 비롯한 여러나라에서 대화형식의 TV서비스를 시행하려는 움직임이 일어나고 있다. 이러한 움직임은 지난 ‘92년 7월 16일 미 연방통신위원회(FCC. Federal Communication Committee)가 그동안 전화회사에 대해 CATV 시업진출을 금지하였던 정책을 바꿔서, CATV에 대항한 경쟁도입과 기반 정보통신망 정비를 목표로 하여 비디오 다이얼톤(VDT(주), Video Dial Tone)이라는 이름하에 공중통신 사업자에게도 영상신호를 전송을 인가함에 따라 시작되었다. VOD서비스와 같은 대화형 TV서비스는 가입자가 원하는 서비스를 시간에 관계없이 댁내의 통신회선(일반전화망, 케이블망, 광화이버망, 위성망)을 통해서 요구 즉시 실시간에 서비스를 받아볼 수 있는 멀키미디어의 통합서비스 방식이다. 도한 이 서비스는 음성통신과 방송의 통합형 서비스로서, 방송국, 전화회사 혹은 서비스 제공업자(ISP ; Information Service Provider)에 의해 제공된 디지탈 영상 및 일반 데이터 등을 압축하여 서버에 저장한 후, 소비자의 요청이 있을 경우에 통신회선을 통해 즉시 서비스 해준다. 이와 같은 대화형 TV 서비스의 구성요소로는 다양한 영상정보 및 데이타를 보유하고 있는 정보제공자, 전화선이나 CATV 또는 위성방송과 연결해 주는 지역별 비디오 서버 및 교환장치, 통신회선을 통해 전송된 서비스를 영상정보로 만들어주고 또한 가입자의 요구를 즉시 정보제공자에게 알려줄 수 있는 가정용 단말기 (STB. Set Top Box)로 이루어진다. 여기서, 비디오 서버는 다양한 대화형 TV 서비스를 제공해 주는 중계자로서, 영화, 홈쇼핑, 홈뱅킹, 대화형 교육, 비디오 게임 등을 가정에서도 가능하게 해 줄 뿐 아니라, 가입자를 관리하는 기능을 가지고 있어서 가입자 정보는 물론, 각종 서비스 사용료, 개인 통계자료 분석 등도 집계할 수 있는 기능을 가지고 있다.(그림1) 본 기고에서는 이러한 대화형 TV서비스 중에 대표적 응용서비스인 VOD 서비스에 사용되는 기술요소와 각국에서 진행되고 있는 VOD 서비스 동향 및 전망에 대해 알아보고자 한다. (주) VDT(Video Dial Tone) : FCC가 ‘92년 7월 16일에 인가한 지역 전화회사에 의한 가정용 영상 전송서비스 및 CATV에 대항한 경쟁도입과 Infrastructure의 정비를 목표로 하여 결정한 내용은 다음과 같다. 지역 전화회사에 대하여 (1) 공중통신사업자에 대하여 서비스 제공자에 대한 영상신호의 전송을 인가(기본서비스), (2) Video Gateway 서비스, 비디오 기기 제공, 서비스 제공사업자에 대한 과금, 요금징수 대행을 인가(고도서비스), (3) 프로그램 제공자에 대하여 자본출자율을 5%로 높이는 외에 (종래는 1%) 업무 관계의 확대(합병회사 설립 및 consultant 계약 등)를 인가. (4) Rural 지역(영업지역의회의 지방)에 대한 직접 프로그램 제공의 특별인가(주민이 1만세데 미만의 지방 공공 단체만 가능, 영업지역내에서는 제한없음), (5) 지방공공 사업체에 의한 영업면허의 불요(지역 전화회사가 직접 사용자에 서비스를 제공하지 않기 때문에 CATV 서비스로는 보지 않기 때문). (6)의 회로의 권고(케이블 정책법으로 결정되어 있는 통신사업자와 CATV회사 자본의 상호보유 금지의 해제) 등이다.

Since the year 2000, the growth rate of domestic manufacturing has declined and the sales and employment have decreased. Major developed countries have established a variety of strategies to strengthen their manufacturing competitiveness, and promote manufacturing innovation through the convergence of technology and ICT. The key to manufacturing innovation is to reduce the time and cost for developing new products using modeling and simulation (M&S) technology in the product design stage. M&S industries, which belong to the top sector of the industry value chain, have a huge ripple effect across other industries. On the other hand, the competitiveness of the domestic M&S industry is weak compared to developed countries and even the definition and classification of domestic M&S companies have not been made. In this paper, by analyzing the Korea Standard Industry Classification (KSIC), five fine industry classifications included in M&S service companies were derived. In addition, the 307 M&S service companies were derived in accordance with the selection procedure of 3 steps from the 11,822 related companies. To analyze the capabilities of domestic M&S service companies, the current status of the selected M&S service companies was investigated. Considering the Korean economy's high dependence on the manufacturing industry, strengthening the competitiveness of manufacturing industry is required by enhancing the capacities and building an ecosystem in domestic M&S services for future sustainable economic growth.

Global courier companies have been devoting to get more customers and profits with different service because of the worse profits from price competition. So, the effort of improving satisfaction of customers through improving courier service qualities is more important than any other time. However, the previous way to measure courier service has limitation that costs lots of time and money from off-line survey. This limitation could be overcome with less effort and costs if utilizing on-line social big data analysis and it is so helpful to improve competitiveness of courier companies. Therefore, I have collected comments from domestic and international courier companies from big data on social network service, analyzed the satisfaction of customers by R and verified the result by comparing with American Customer Satisfaction Index (ACSI) and Korea National Customer Index (NCSI) in this research. I found out the result depicts clear correlation between SNS analysis and customer satisfaction. This study can be the foundation to predict customer satisfaction easily by utilizing real time SNS information.

There are considerable amount of man power and time spent for analysis and selection of various materials due to the inadequate application system and rapid searching process of material related information in each stage of building production process. Also, due to the insufficiency in recycling system of important information created for each process, they are hoarded at each task stage and project completion. As a result, because of the repetition of the similar/identical tasks on each process, it is the major reason for impeding the efficient employment of manpower of the company and decreasing competition of the company. Moreover, in selecting finish material in the project field, there are many difficulties due to the lack of technical information such as product characteristics and field applications. The construction quality also affects the profit and loss of the product which calls for a need to develop continued information management system that the finish material related examples could be shared in real time. The objective of this study is to propose a building finish material information which the real time research and application is possible to raise the productivity. TO do this, the current material information task status analysis and questionnaire research should be conducted to understand the demand of system development and reflect the result onto the system for easy access and application. Therefore, the building finish material information system for enhancement of productivity of construction task proposed in this study is expected to be utilized in enhancement of construction quality, maximization of company profit, and strengthening of company competition.

This study was conducted to investigate the adsorption-desorption characteristics of herbicide paraquat on clay minerals, humic materials, and soils under the laboratory conditions. Adsorption time of paraquat on clay minerals was faster than organic materials and soils. Adsorption amount on montmorillonite, 2:1 expanding-lattice clay mineral, was largest among the adsorbents tested. The adsorption capacity of paraquat was approximately 21 % of cation exchange capacity in soils, 45.1 % in kaolinite, and 80.6% in montmorillonite. Humic materials, humic acid and fulvic acid isolated from soil II, adsorbed larger amount of paraquat than kaolinite and soils. Distribution of tightly bound type of paraquat was larger in clay mineral and soils but loosely bound type was larger in humic acid and fulvic acid. In oxidized soil, the adsorption amount of paraquat was decreased to 85.1-95.5% of original soils. Distribution of unbound and loosely bound type of paraquat was decreased in oxidized soil but tightly bound type was increased. The competition cations decreased paraquat adsorption on humic materials and soils but not affected on montmorillonite. No difference was observed as the kinds of cations. In cation-saturated adsorbents, the adsorption amount was decreased largely in humic materials and soils but decreased a little in montmorillonite. The tightly bound type of paraquat in all adsorbents was not desorbed by pH variation, sonication, and cation application but loosely bound type was desorbed. However, the desorption amount was different as a kinds of adsorbents and desorption methods.
