The introduction and application of IT(Information Technology) to a company has become to be viewed as a key factor for the business competitiveness and improved productivity. This study presents an approach to evaluation of a company's informatization level, which is especially appropriate for small and medium enterprises. The proposed evaluation method, based on the traditional questionnaire approaches, considers the various characteristics of the company, e.g., types of business, characteristics of customers, and locations of supply chains etc. A web-based system was developed to enable users to obtain the evaluation results from the evaluation method. The system also provides a function to produce valuable strategies for informatization by utilizing the case base which will be cumulated by repetitive evaluation requests. Finally, a real case was analyzed in order to verify the practicality of the evaluation system.

The present study provides a theoretical investigation on pioneering advantage based on reference dependence and loss aversion effect under prospect theory (Kahneman and Tversky, 1979). Behavioral explanations for pioneering advantage are provided from two different perspectives: one based on the prototypicality and the other on the utility uncertainty of the option. A pioneer brand creates the product category and makes a strong impression in customers' mind, and thus becomes the most representative or prototypical option of the category. In addition, the pioneer brand becomes the first option to be experienced by the majority of consumers in the product category, thus has the lowest level of utility uncertainty compared with the late movers. This study integrates the previous accounts for pioneering advantage by showing that consumers have higher preferences for the most prototypical and the least uncertain option based on loss aversion and reference dependence effect. This study suggests that firms should carefully analyze the consumers' loss aversion and perceived uncertainty and prototypicality of their products in order to develop effective market entry strategies.

The shadow enhancer of the short gastrulation (sog) gene directs its sequential expression in the neurogenic ectoderm and the ventral midline of the developing Drosophila embryo. Here, we characterize three unusual features of the shadow enhancer midline activity. First, the minimal regions for the two different enhancer activities exhibit high overlap within the shadow enhancer, meaning that one developmental enhancer possesses dual enhancer activities. Second, the midline enhancer activity relies on five Single-minded (Sim)-binding sites, two of which have not been found in any Sim target enhancers. Finally, two linked Dorsal (Dl)- and Zelda (Zld)-binding sites, critical for the neurogenic ectoderm enhancer activity, are also required for the midline enhancer activity. These results suggest that early activation by Dl and Zld may facilitate late activation via the noncanonical sites occupied by Sim. We discuss a model for Zld as a pioneer factor and speculate its role in midline enhancer activity.

Wharton Esherick (1887-1970) is the pioneer of the Studio Furniture movement which was emerging after the Second World War in the United States. As Esherick began to work on his studio at Paoli, Pennsylvania from 1926, he became enormously influential in the Stuido Furniture movement until his death in 1972. He was connecting the English Arts and Crafts ideal to the post-war craft revival. As the work of William Morris did, in the period of consumerism Esherick's furniture gave a chance to purchase unique furniture to people who wanted a different taste. Not only his furniture is unique and hand-crafted also has sculptural quality which made his followers to see furniture as a different possibilities. His work was influential to the people who followed him after the war such as Arthur Carpenter, Wendell Castle, and Sam Maloof. In the roots of the craft revival, it is hard to underestimate the contribution of Esherick's notion of sculptural furniture.

Recently, the affiliates of the Ministry of Information and Communication have been conducting a performance evaluation study on IT policy projects, based on the performance evaluation model of the U.S. Office of Management and Budgets, with regard to investment in computerization. The performance evaluation model for the policy project could provide the objective information required for the planning, development, and operation of the policy project. However, the performance of the most policy project is likely to be evaluated using the subjective evaluation criteria of evaluators. Therefore, this case study evaluates the relative efficiency using DEA (Data Envelopment Analysis) in order to improve the performance evaluation method of the digital pioneer' project implemented by the Korea IT Industry Promotion Agency. The improvement value of inefficient Decision Making Units (DMUs) was measured by a static efficiency analysis. The measured value will suggest a objective viewpoint of the performance between DMUs to evaluators. In doing so, it will show an appropriate direction for the policy project to be evaluated successfully.

Since Korea disclaimed to open the ports, Korean architecture has met the impetuous transformation. Although there would be various factors of this transformation, the new-coming architecture by missionary seemed to be a significant one, and many researches have been carried out on this theme in diverse viewpoints. However, because these researches have preponderated on the Catholic tradition, it is deficient for clarify the whole history of mission architecture. Therefore, this research has the meaning to enrich the history of Korean modern architecture by making balance. First of all, this paper is focused on the activities of one missionary, Graham Lee. He is a practical missionary at the beginning, his architecture made a critical influence in Korean traditional architecture. Graham Lee was born in Rock Island, Illinois, 1861, and he determined to become a missionary through grown up. He spent his boyhood by working as a plumber for his purpose and studied in a university afterward. Graduating of McComick Theological Seminary, he was nominated as a pioneer of Pyeng Yang Mission Station and set foot in Korea, September of 1892. Since then he started to erect missionary facilities in Pyeng Yang, such as Well House(1898), Pyeng Yang Central Church(1900-1901), Pyeng Yang Academy(1902). These all his works are designed with eclectic style which shows western and Korean traditional style intermingled. This unique characteristic made a profound influence to the Korean mission architecture afterwards. Especially, the L-type plan of Pyeng Yang Central Church, which is first shown by him, is recognized very unique, and this plan type had been spread all over the country. Therefore the L-type plan became the peculiar feature of the early Korean churches. Furthermore, working with Korean carpenters, he taught them new skills of modem buildings. After that, they were expanded out northern part of Korea and took the roles of master builders. According to this expansion, his particular style had got spread and had been settled as a unique eclectic style in Korean modern architecture. In the conclusion, he is evaluated to be a critical pioneer missionary, who left a big influence on the frame work of Korean modern architecture in the transitional times.
