Malware authors spread malware variants in order to evade detection. It's hard to detect malware variants using static analysis. Therefore dynamic analysis based on API call information is necessary. In this paper, we proposed a malware family recommendation method to assist malware analysts in classifying malware variants. Our proposed method extract API call information of malware families by dynamic analysis. Then the multiple sequence alignment technique was applied to the extracted API call information. A signature of each family was extracted from the alignment results. By the similarity of the extracted signatures, our proposed method recommends three family candidates for unknown malware. We also measured the accuracy of our proposed method in an experiment using real malware samples.

유사한 제품 패밀리들에 대한 생산성 향상과 재사용성을 향상시키기 위해 Product Line Engineering에 대한 관심이 높아지고 있다. PLE를 이용한 소프트웨어 개발이 기존 방법들보다 생산성과 재사용성을 향상시키기 위해서는 제품 패밀리에 대한 도메인 분석을 통한 핵심 자산을 효율적으로 구축해 놓아야 한다. 현재 SI업체에서 많이 이용하고 있는 프레임웍처럼 PLE의 핵심 자산들을 만들기 위해서는 제품 패밀리 내의 제품들의 특징을 공통성과 가변성으로 분리하고 이들 특성들 간의 관계성을 추출하는 작업이 선행되어야 한다. 본 논문에서는 도메인 전문가 또는 제품 패밀리 분석가들이 제품 패밀리 특징들을 추출하고 모델링하기 위한 방법을 제안하고자 한다.

본 연구는 패밀리 레스토랑 맥락에서 패밀리 레스토랑 내 환경에 대한 젊은 남녀의 지각 차이를 검증하고자 하였다. 성별 주제에 대한 연구는 소비자 행동 연구에서 기본적인 조절 변수로 널리 사용되고 있으며, 패밀리 레스토랑 업게 에서도 점포환경의 마케팅 믹스 전략으로서 가장 일반적으로 사용되고 있다. 자료는 세 개의 패밀리 레스토랑을 방문한 382명의 고객들로부터 수집하였으며, SPSS LISREL 통계프로그램을 사용하였고 가설검증을 위하여 신뢰도분석과 확인요인분석을 실시하였다. 그 결과는 다음과 같다. 첫째, 남성이 여성보다 식음료 요인에 대하여 더욱 민감한 것으로 나타났다. 둘째, 이벤트 요인들은 여성보다는 남성이 레스토랑 내 환경을 판단하는데 유용한 기초를 제공하였다. 셋째, 디자인 요인들이 여성보다 남성에서 성별차이를 설명하는데 중요한 역할을 하였다. 요약하면, 본 연구의 결과는 레스토랑 내 환경믹스 전략들은 성별에 따라서 달라져야 한다는 것을 보여주고 있다. 최근 젊은 남성들의 기호는 전통적 패러다임에서 변화하고 있으며, 심미적으로 스타일적이며, 감성적 지향적 문화를 추구한다. 따라서 이러한 결과들은 식음료산업 트랜드에 중요한 방안을 제공해준다. 연구의 마지막 부분에, 이론적 기여도, 관리적 시사점, 연구의 한계점, 그리고 향후 연구방향이 제시되었다.

In this study, the factors of customers' selection attributes on family restaurants, brand images, and the effect on revisit intention were analyzed. Specifically, the effects of brand, store, and price, which are sub-factors of family restaurants, on customers' revisit intention, store/service value, brand value, food effect, and revisit intention were examined. Among the brand image and four family restaurant selection attributes derived from this study, the most significant selection attributes were the cleanliness and hygiene of family restaurant stores and the menu and quality of family restaurant stores. Therefore, it can be said that family restaurants are price attributes and store/service attributes that have the most influence among the selection attributes. Through this, we intend to provide basic data necessary to find development plans through strategic plans for family restaurant management in the future.

Today, a web site is used as a strategic method to fulfill a company's objectives. In particular, a web site provides a service for customers to find satisfaction in visiting family restaurants, and it recently has helped to attract the interest of a variety of customers. Currently, companies that manage family restaurants operate their Web sites as strategic tools and use them to perform public relations and marketing of their restaurants. This effort influences management and helps to improve the business and profitability of family restaurants. The research model of this study is an expansion of the Technology Acceptance Model (TAM) and examines whether ease of use and usefulness of family restaurant web sites influence the relationship of intention to use, actual use, and recommendation to use by gender. The results of this research would suggest that web sites are useful in establishing a marketing strategy for companies that operate family restaurants.

The recent drastic increase of imported foreign restaurants provided the importance of service quality and the customer satisfaction is considered as the most important factors for the business activity. In order to identify the important factors for the customer satisfaction of the family restaurant in Korea, we attempt to test the validity of host call service as a significant variable in the family restaurant using Fishbein behaviour model. Based on literature review, the empirical study was conducted using the questionnaires for customers of the family restaurant in Seoul. Descriptive statistics, t-test, F-test and regression analysis were made of the gathered questionnaires using SPSS programs. The results shows that four hypotheses established in this study were significant. Therefore, host call service in the family restaurant should be introduced to increase the customer satisfaction. In conclusion, it proved that host call service in the family were the important factors that could satisfy the customers and the family restaurants will have to make a great effort to develop the differentiated service so as to enhance their competitiveness.

A method to find the nearly optimal PSNR values for compression was tried to remotely sensed images. There is no rule to find the best wavelet pairs for image processing. The expected wavelet pairs following the suggested algorithm showed the optimal result for various kinds of images. Firstly, the PSNR variations with three wavelet families were analyzed. In many cases the longer wavelet filter shows the higher PSNR value, but the rate is getting less in orthogonal wavelet families. Wavelets with moderate filter length are suggested at the point of computational cost. For biorthogonal families it was hard to predict from the length of filters. Multiresolution wavelet analysis was used up to level 3 with three kinds of wavelet families. Biorthogonal wavelet family showed irregular pattern to get the maximum PSNR values, while orthogonal wavelet families showed regular pattern. In orthogonal wavelet families the nearly optimal wavelet pair can be predicted from the level 1.

The purpose of this study was to understand the influence of corporate association in family restaurants upon the customer's service valuation and company evaluation and to empirically analyze whether the service valuation plays a mediating role between the corporate association and the company evaluation. Self-administered questionnaires were completed by 301 customers and the data were analysed by frequency, factor analysis, reliability analysis, correlation analysis and multiple regression analysis. The primary results are as follows. Multiple regression analysis, to verify the hypothesis, showed that corporate association(corporate competence association $\beta$=0.636; corporate social responsibility association $\beta$=0.091) in family restaurants had positively significant influence upon service valuation, and service valuation($\beta$=0.567) had positively significant influence on company evaluation. As a result of analyzing the mediating effects, the direct effects(corporate competence association $\beta$=0.166; corporate social responsibility association $\beta$=0.123) of the corporate association in family restaurants upon customer's corporate evaluation were indicated to be smaller than the total effects(corporate competence association $\beta$=0.430; corporate social responsibility association $\beta$=0.161). Accordingly, the partial mediating effect was surveyed to exist that has influence upon company evaluation through service evaluation without explaining 100% directly in evaluation on corporate association.

The purpose of this study is to suggest positioning strategy according to franchising family restaurant brands. Discriminant Analysis was utilized to suggest methodological framework that seeks to find their relative positions in the family restaurant brands. As a result, the results show that five factors (employee service, physical environment, marketing, accessibility, and food quality) were extracted from Exploratory Factor Analysis that contains twenty three questions related to service quality of family restaurant. Second, Discriminant Analysis revealed that three factors out of five including employee service, physical environment, and accessibility showed the highest discriminant power. Based on the three factors, positioning maps were made and the location of four brands were identified. Third, service quality, satisfaction, and willingness had a significant influence on revisit intention.
