Location-based advertising or application has been one of the drivers of third-generation mobile operators' marketing efforts in the past few years. As a result, many studies on location-based marketing or advertising have been proposed for recent several years. However, these approaches have two common shortcomings. First. most of them just suggested the theoretical architectures, which were too abstract to apply it to the real-world cases. Second, many of these approaches only consider service provider (seller) rather than customers (buyers). Thus, the prior approaches fit to the automated sales or advertising rather than the implementation of CRM. To mitigate these limitations, this study presents a novel advertisement recommendation model for mobile users. We call our model MAR-CF (Mobile Advertisement Recommender using Collaborative Filtering). Our proposed model is based on traditional CF algorithm, but we adopt the multi-dimensional personalization model to conventional CF for enabling location-based advertising for mobile users. Thus, MAR-CF is designed to make recommendation results for mobile users by considering location, time, and needs type. To validate the usefulness of our recommendation model. we collect the real-world data for mobile advertisements, and perform an empirical validation. Experimental results show that MAR-CF generates more accurate prediction results than other comparative models.

서울,충북지역의 주부 590명을 대상으로 시판김치의 사용실태를 설문 조사한 결과는 다음과 같다. 시판김치의 구매는 30대에서 많았고 고졸의 경우에 많았다. 직업 유무, 월수입, 주거 및 가족형태는 시판 김치 이용과 유의적인 차이를 보이지 않았지만 연령과 교육수준에 따라서는 유의적인 차이(P<0.05)연령이 낮을수록, 교육수준은 높을수록 시판김치를 이용하는 것으로 나타났다. 시판김치의 선호도는 배추김치가 73.2%로 높게 나타났고, 시판김치 구매 장소는 주로 대형 수퍼마켓을 이용하였으며, 1회 구매분량은 3포기를 구맹하는 경우가 가장 많았다. 구매 이유는 편리하기 때문과 가사와 자녀로 시간이 부족하여 구매하는 경우가 많았다. 또한 어떻게 담그는지 몰라서 구매하는 경우도 있었다. 제품 선택 동기는 주로 구맹 경험에 의해서 시판결치를 구입하였다. 광고를 보고 구매하는 경우도 있었고 재료나 점원의 권유에 의해서 구매하는 경우도 있었다. 응답자들이 가장 맣이 지적한시판 김치으 개선점은 가격이었다. 가격이 비싸다고 생각하는 경구가 많았다. 그밖에 위생명, 맛의 다양성, 분량과 용기의 개선도 필요하다고 생각하는 경우가 있었다. 향후 시판김치 구매 여부에 대해서는 73.2%가 긍정적으로 응답하여 앞으로도 시판김치를 구매할것으로 나타났다. 이상의 결과를 보면 상품화 된 김치의 이용은 젊은 세대뿐만 아니라 교육수준의 향상에 의해 주부들의 라이프 스타일이 식생화에도 반영되기 때문에 계속증가할 것으로예측된다. 그러므로 본 연구의 결과를 토대로 하여 가격면, 위생면, 맛의 다양성, 분량과 용기 등에 있어서도 한 단꼐 개선된 고품질 김치의 생산이 요구된다고 볼 수 있다.

Consumption pattern of Ramyon (fried instant noodle) by middle school students at age of 13 ∼15 years in Kangwon-do area was surveyed by questionaire. About 67% among 866 students consumed Ramyon more than once per week. On the whole, common Ramyon was frequently consumed as a kind of substitues for supper sand between meals at home because of its convenience. The advertisement had strong effect on the selection of ramtron. Consumers considered that taste of soup is important quality factor of Ramyon In terms of the texture of cooked noodle, the most desirable was chewy and hard texture. The most undesirable was swollen and mushy texture. The most desriable and undesirable taste of soup was respectively spicy and greasy taste. At present, no significant difference in consumption pattern betsween sex were observed in most cases.

Consumption pattern of Ramyon (fried instant noodle) by elementary school pupils at age of 10∼13 years in Kangwon-do area was surveyed by questionaire. About 64% among 675 pupils consumed Ramyon more than once or twice per week. On the whole, common Ramyon was frequently consumed as a kind of substitutes for normal meal at home because of its convenience. The advertisement had strong effect on the selection of Ramyon. Especially, gummy texture of noodle and hot taste of soup are playing as a vital role in choosing Ramyon. At present, no significant differences in consumption pattern between sex were observed in most cases.

To adapt to the constant change in the foodservice industry, dietary life is not only evolving variously and complicatedly, but eating-out styles are also changing fast. In this reality, this study is intended to examine the effects of marketing mix strategies on perceived value and loyalty in Korean restaurants. To achieve this, a survey was carried out to total 300 customers of Korean restaurants in Seoul from June 11 to June 30, 2013. The results were as follows. First, service experience, price and store image in Korean restaurants had a positive effect on the perceived value. Second, price, advertisement and store image in Korean restaurants had a positive effect on the loyalty. Third, the perceived value had a significant positive effect on the loyalty. As stated above, service experience, price and store image, and price, advertisement and store image in Korean restaurants had an effect on the perceived value and the loyalty, respectively. Also, the perceived value had an effect on the loyalty. Consequently, these factors are very useful as marketing mix strategies in Korean restaurants.

The applications of augmented reality technology is increasing in the several field by IT convergence and we find augmented reality application easily in the smart device application area. And then, to attempt to use augmented reality technology in advantage, exhibitions and performances was activated. However, it less than other fields of augmented reality technology expertise yet. Among them services to Use in fusion with monitoring are lacking. In this paper, we proposed the augmented reality monitoring technology based on smart device. It is able to incorporate QR-code which is already building for the purpose of advertising promotional materials with augmented reality technology in many areas. Therefore, it is able to utilize unattended building or automation equipment facilities using QR-code and environmental monitoring sensor in the industry.

This study examined the effect of store fit perceived by consumers for improved signboards on visit intention to store, and the mediating effect of informativeness, entertainment, and irritation. The survey was conducted from November 7 to November 18, 2022 with 150 undergraduate and graduate students who had experience visiting areas where signboard improvement projects were implemented. The collected data were analyzed using SPSS 26.0 and PROCESS Macro 4.2. The results showed that store fit had a positive effect on visit intention to store by mediating informativeness and entertainment. This results suggest that practitioners of local governments and government agencies and store owners should consider store fit of signboards as important when participating in signboard improvement projects.

This study aims to investigate language society cultural aspects in a community, examining and comparing linguistic errors of English signboards (ES) at home and abroad. The data comprised the ES in 5 cities, Korea and in Paris, France. The findings showed that the errors of the ES in Korea reached to 39.2%, whereas those in Paris contained 24.7%. In Korea, ES and errors were the most in Myeong-dong area. In Paris, the most ES were in the area of Eiffel Tower, but the most linguistic errors appeared at the 3, 4 districts of Marais. Those errors belonged to most in the business of drink, food, and clothes in turn in Korea, while this was the case in the field of clothes, food, and culture in Paris. The frequent errors were classified into semantic, morphologic, and syntactic aspects in turn. The regulations on signboards of foreign languages existed but were not abided by in the both countries. Thus, more practical and reasonable devices and policies are required to establish a more harmonious atmosphere of the ES.

최근 사용자의 멀티미디어에 대한 요구의 증가가 VOD (Video-on-Demand) 서비스를 발전시키게 되었다. VOD는 엔터테인먼트나 원격 교육, 광고 및 정보 등 많은 분야에서 사용되고 있다. 이러한 VOD 서비스는 많은 디스크 I/O와 네트워크 I/O를 요구하며 기존 웹 서버 시스템과 비교했을 때 오랜 시간동안 서비스를 해야 하는 특징을 가지고 있다. 또한 VOD 서비스는 많은 네트워크와 디스크의 대역폭을 요구하며, 서비스의 QoS에 민감해서 사용자 응답시간이 길어지면 사용자 요청의 취소율이 높아지게 된다. 따라서 불만족스러운 서비스의 증가로 네트워크 부하만 증가하게 된다. 이러한 기존 웹 서버 환경과는 다른 부하의 패턴이 있는 VOD 서비스 환경에서는 부하를 균형적으로 분배하여 서비스의 QoS를 높이는 것이 매우 중요하다. 본 논문에서는 분산 VOD 시스템 환경에서 부하를 효율적으로 분산하기 위해 계층형 분산 VOD 시스템 모델과 사용자 요청 패턴의 히스토리와 유전 알고리즘을 기반으로 한 스케줄러를 제안한다. 본 논문에서 제안한 계층형 분산 VOD 시스템 모델은 서버들을 지역적으로 분산하고 제어 서버를 지역마다 설치하여 지역에 있는 VOD 서버들을 관리하도록 구성한다. 사용자 요청을 지역 서버군 내에서 분산시키기 위해서 히스토리를 기반으로 한 유전 알고리즘을 사용한다. 이러한 히스토리 정보를 기반으로 유전 알고리즘의 적합도 함수에 적용하여 VOD 시스템을 위한 유전 알고리즘과 유전 연산을 구현한다. 본 논문에서 제안한 부하 분산 알고리즘은 VOD 서비스 환경에서 사용자 요구에 대한 부하를 보다 정확하게 예측하여 부하를 분산할 수 있다. 본 논문에서 제안한 계층형 분산 VOD 시스템의 부하 분산 알고리즘의 성능을 테스트하기 위해 OPNET 기반 시뮬레이터를 구현한다. 라운드로빈(round-robin) 방식과 랜덤(random) 방식과의 비교 실험을 통해 본 논문에서 제안한 부하 분산 알고리즘의 성능을 평가한다. 비교 실험을 통해 본 논문에서 제안한 알고리즘이 보다 안정적인 QoS를 제공하는 것을 보여준다.
