Purpose: To develop efficient PL response system, SMEs should decide which component of PL response system is important and implemented with priority under limited resources. To accomplish this goal, we propose strategic priority components of PL response system for SME manufacturer. Methods: We categorize the components of PL response system based on prior research results - System, Organization, Training, Technology, Cost, and Awareness. AHP (Analytic Hierarchy Process) is applied to extract important components of PL response system, which is used in assigning the priority of component. To analyze effects of each components, performance sensitivity analysis is applied. Results: The survey analysis results show Technology is the most important components. Organization and Cost component are follows. As the importance of Technology is changed, we can find Organization, Cost is second and third important components. Conclusion: Our research shows Technology which is related to make a safe product with systematic process, is a basic enabler of PL response system. Also, building a PL team and securing a budget for PL activity should be carry out with limited resources.

This study analyzed the buying patterns of American and Korean female college students in terms of criteria for clothing selection； store preferences； criteria for store selection； fashion information sources； expressions of customer dissatisfaction； purchasing frequency and motivations for purchasing clothes. The study was implemented through self-administered questionnaires which were back translated for validity. The samples consisted of 730 female college students majoring in the fields related to clothing and textiles： 310 U.S. and 412 Korean students. Likert scales were used for most measures with 1＝never or very unimportant and 5＝always or very important. Data were analyzed by factor analysis, analysis of covariance, Duncans multiple comparison, and t-test. Results are as follows： 1) Design factor was the most important criteria in clothing selection with no differences between country groups. There were, however, significant differences for psychological exhibition factors, practical and economic factors. 2) Both groups preferred specialty and department stores, with department stores more popular in Korea. 3) Merchandise was the most important store selection criterion and fashion magazines and self-experience were rated as the most important information sources for the both groups. 4) Korean group expressed their dissatisfaction with and observable problem with a product before purchase more often than U.S. group, but the U.S. group was more vocal about color loss or shrinkage after care procedures. 5) Some clear differences between the two countries emerged. Marketers targeting American consumers should pay more attention to practicality and service； to Korean consumers more symbolic meaning of products.

Identifying disease genes from human genome is a critical task in biomedical research. Important biological features to distinguish the disease genes from the non-disease genes have been mainly selected based on traditional feature selection approaches. However, the traditional feature selection approaches unnecessarily consider many unimportant biological features. As a result, although some of the existing classification techniques have been applied to disease gene identification, the prediction performance was not satisfactory. A small set of the most important biological features can enhance the accuracy of disease gene identification, as well as provide potentially useful knowledge for biologists or clinicians, who can further investigate the selected biological features as well as the potential disease genes. In this paper, we propose a new stepwise random forests (SRF) approach for biological feature selection and disease gene identification. The SRF approach consists of two stages. In the first stage, only important biological features are iteratively selected in a forward selection manner based on one-dimensional random forest regression, where the updated residual vector is considered as the current response vector. We can then determine a small set of important biological features. In the second stage, random forests classification with regard to the selected biological features is applied to identify disease genes. Our extensive experiments show that the proposed SRF approach outperforms the existing feature selection and classification techniques in terms of biological feature selection and disease gene identification.

오늘날 시스템 사용에 있어 가장 큰 문제 중의 하나는 사용자의 요구를 잘 반영하지 못하는 데에 있다. 이러한 사용자의 요구를 반영하기 위해 기존의 많은 연구들은 기기나 서비스 자체에 초점을 두어 중요한 사용 품질요인을 규명하여 왔다. 그러나 모바일 컴퓨팅 서비스는 언제 어디서나 사용이 가능하기 때문에 사용 품질요인이 기존의 정보 시스템과는 다르게 나타나게 된다. 이러한 상황에도 불구하고 기존 연구들은 사용 환경을 고려하여 중요한 사용 품질요인을 도출하기 보다는 기기나 서비스 자체에 초점을 두어 연구를 진행하였다. 본 연구에서는 모바일 컴퓨팅 서비스를 대상으로 모바일 컴퓨팅 서비스 특성에 맞는 중요한 사용 품질요인을 도출하고자 하였다. 이를 위해 대표적인 모바일 컴퓨팅 서비스로 모바일 데이터 서비스를 선정하고 모바일 데이터 서비스 사용자를 대상으로 맥락 집중 인터뷰를 실시하였다. 인터뷰 실시 후 분석 결과, 모바일 컴퓨팅 서비스는 기존 정보 시스템에서 중요하게 나타났던 사용 품질요인과 다르게 나타났다.

One of the historical origins of the modern science education was investigated in this paper. From the view point of the pansophistic educational philosophy which emphasized "man should teach completely all things to all mankind(Omnes, Omnia, omnino)", J.A.Comenius proposed in his book "Didactica magna"(1658) that 'physica' should be learned as one of the most important school subjects. He suggested the completion of human being as a wholeness of the universe could be achieved through the physics teaching. His ideas of science education was, however, directed not to the 'rational konwledge' about the natural world, but to the 'divine wisdom'. His main thoughts and influences on science education can be summarized as follows: 1) The human being as a God's image should know the divinely created nature, because the invisible God's existence can be sensorially recognized in the nature. 2) Physics or science should be regarded as more important objects than verbal learning in general school education. 3) The cognitive union between the words('representative' or 'das Dargestellte') and things('presentative' or 'das Dargebotene') can be achieved through the objects lesson ('Anschauungsunterricht') 4) The realistic and sensor-cognitive learning theory of the object lesson is yet very important especially in the science education of elementary school, even though the inquiry learning process has became more important in the last years. 5) The religious aspect of his idea could not satisfy the social needs of industrialization and the development of professonal technics in the 18 to 19th century.

This paper presents a study on the Palazzo Firenze of B. Ammannati, designed between 1550~572. He was active in Rome and Firenze in the middle of 16th Century. His most important project, such as Palazzo Pitti, is located in Firenze. But there are some projects that are important as well as Palazzo Pitti in Rome, such as villa Giulia and Palazzo Firenze. Usually, in the history of Western Architecture, the period in which Ammannati was active is denominated as late-Renaissance or Mannerism. In this period there was very important progress in field of artistic theory. There were active many great Masters such as Michelangelo, Vignola and Giulio Romano. But, over the all, the most important characteristic of this period was a transition period between Renaissance and Baroque. This paper try to reveal such characteristics reflected in architectural projects designed in this period, focusing on, over the all, B. Ammannati and his Palazzo Firenze project.
