The purpose of this study is to propose a method of developing an improved Hanok. To achieve this, an investigation was carried out on the factors of the main floor plan in the improved Hanok development and an interview was conducted with residents who live in the improved Hanok development. The conclusions obtained through this study are as follows: First, The shape of 一 was marked at the highest in the Korean traditional plan types such as 一, ㄱ and 田. It is considered that this reduces the cost of construction by simplifying the structure of the roof. Second, the size was consisted of $5{\times}3$ Kan, the Korean traditional module that determines the number of columns and expresses the position of the inner wall. However, the Kan measure ments for the bathroom and multi-purpose room differed. Third, 57.6% of the 2 bedroom units were investigated. However, 60% of the residents preferred 3 bedroom units. Fourth, the results of the relationship between the living room and the kitchen showed that the residents preferred L+DK type to LDK type by 54.2% and 45.8% respectively. Fifth, the residents preferred a bathroom constructed next to the bedroom because they considered that the improved Hanok development would be used as an Inn during holiday periods. Moreover, they desired a plan where the bathroom could be directly entered from the outside. Sixth, the design for the improved Hanok development should have a suitable multipurpose-room because 72.5% of the residents have extended their house to accommodate such a room. Seventh, 61% of the improved Hanok units had an entrance space, which does not exist in Korean traditional houses. For this reason, the Korean traditional floor (: the Maru) was avoided due to its inconvenience.

The purpose of this study was to divide into a few groups of Bibimbabs with distinctive menu patterns and accompaniments from 484 Bibimbab menus of 360 elementary school foodservices around Busan city and Gyeongnam province. The menus were collected from the internet(http://www.kdclub.com) and the home page of elementary schools from December, 2004 to September, 2005. Moreover, Bibimbabs with high frequency were analyzed by seasons and regions to give informations for menu planing and developing in elementary school foodservices. The serving frequency of Bibimbabs was significantly different among seasons, highest in summer and lowest in winter. Kongnamulbibimbab and Bomnamulbibimbab were highest in frequency in rural areas meanwhile, Sanchaebibimbab, and Chamchibibimbab were frequently served in Busan. The basic structure of Bibimbab meal based on main dish, soup, kimchi and one or two accompaniments consisted of 'side dish', 'fruit & beverage', or 'starchy food & dessert'. Thus, most of the Bibimbab meals were composed of 4${\sim}$5 dishes. Five groups of Bibimbabs were suggested by the menu patterns and kinds of soups. Soups, fruit & beverage, and kimchi were included in the menu patterns of nearly all groups of Bibimbab. However, side dishes and strachy foods & desserts were included of excluded according to the groups of Bibimbabs. Some kinds of soups and side dishes were different among the groups of Bibimbab. These results suggest that the cost, avaliable labor and seasonal constraints contributed mainly to the numbers and kinds of accompainments in the Bibimbab meals. However, taste and sensory balance were also considered in the Bibimbab menus in the School Lunch Program.

Final construction project cost is significantly determined by construction rate. The Industrialized Building System (IBS) was promoted to enhance the importance of prefabrication technology rather than conventional methods in construction. Ensuring the stability of a building constructed by using IBS is a challenging issue. Accordingly, the connections in a prefabricated building have a basic, natural, and essential role in providing the best continuity among the members of the building. Deficiencies of conventional precast connections were observed when precast buildings experience a large induced load, such as earthquakes and other disasters. Thus, researchers aim to determine the behavior of precast concrete structure with a specific type of connection. To clarify this problem, this study investigates the capacity behavior of precast concrete panel connections for industrial buildings with a new type of precast wall-to-wall connection (i.e., U-shaped steel channel connection). This capacity behavior is compared with the capacity behavior of precast concrete panel connections for industrial buildings that used a common approach (i.e., loop connection), which is subjected to monotonic loading as in-plane and out-of-plane loading by developing a finite element model. The principal stress distribution, deformation of concrete panels and welded wire mesh (BRC) reinforcements, plastic strain trend in the concrete panels and connections, and crack propagations are investigated for the aforementioned connection. Pushover analysis revealed that loop connections have significant defects in terms of strength for in-plane and out-of-plane loads at three translational degrees of freedom compared with the U-shaped steel channel connection.

This study aims to investigate the impact of wide use of digital technology, in particular, the Internet, on innovation process and corporate strategy in electronics industry. The introduction of digital technology has changed innovation process, business model and organizational structure of the electronics companies. With the introduction of digital technology, the entire value chain of electronics industry from procurement, sales, and marketing to R&D and manufacturing has been restructured. E-commerce has been a major agenda for e-business. Recently, collaboration among electronics companies through e-marketplace has emerged as an important issue. A web-based e-commerce standard, so called RosettaNet, has been developed for facilitating e-transactions of electronics firms. The development of digital technology has dramatically increased the processing speed and sophisticated the virtual reality technology. As simulation becomes easier and more effective, the uncertainty and risk involved in R&D has decreased significantly. Another positive impact is closer cooperation between R&D and manufacturing functions. Taking advantage of automated and flexible production technology, has a new type of firm, so called, EMS (Electronics Manufacturing Services) emerged, whose strategic focus is on manufacturing only. The EMS can be seen as a kind of innovative organization, that is, a modular organization for production function. Digital technology has made convergence of computer and communication possible at early years but right now the convergence has been accelerated in extensive areas of communication, broadcasting, information appliances, software, contents, and services. Firms' effort for an innovative product and service has been intensified and the competition for a new standard product and service has become severe in electronics industry. Business activities are always realized in a specific organizational context. Accordingly building up innovation-friendly organization has emerged as a critical concern. Due to the striking decrease of transaction cost, a network type of organization has proliferated, and a business function turns into a modular organization. As a whole, digital technology has pushed electronics firms into developing their own business model, which takes consideration of standardization of business platform and their core competency.

Business analytics is a management tool for achieving significant business performance improvements. Many organizations fail to or only partially achieve their business objectives and goals from business analytics. Business analytics adoption is a multi-stage complex activity consisting of evaluation, adoption, and assimilation stages. Several research papers have been published in the field of business analytics, but the research on multi-stage BA adoption is fewer in number. This study contributes to the scant literature on the multi-stage adoption model by identifying the critical themes for evaluation, adoption, and assimilation stages of business analytics. This study uses the thematic content analysis of peer-reviewed published academic papers as a research technique to explore the key themes of business analytics adoption. This study links the critical themes with the popular theoretical foundations: Resource-Based View (RBV), Dynamic Capabilities, Diffusion of Innovations, and Technology-Organizational-Environmental (TOE) framework. The study identifies twelve major factors categorized into three key themes: organizational characteristics, innovation characteristics, and environmental characteristics. The main organizational factors are top management support, organization data environment, centralized analytics structure, perceived cost, employee skills, and data-based decision making culture. The major innovation characteristics are perceived benefits, complexity, and compatibility, and information technology assets. The environmental factors influencing BA adoption stages are competition and industry pressure. A conceptual framework for the multi-stage BA adoption model is proposed in this study. The findings of this study can assist the practicing managers in developing a stage-wise operational strategy for business analytics adoption. Future research can also attempt to validate the conceptual model proposed in this study.

Unit testing is one of the test levels, which tests an individual unit or a group of related units. Recently, in Agile Development or Safety-critical System Development, the unit testing plays an important role for the qualities. According to the definition of unit testing, it is supposed to be done by the developers of units. That is because test models for the unit testing refers to the structure of units, and others but its original developers hardly can understand the structures. However, in practice, unit testing is often asked to be done without the original developers. For example, it is when faults are revealed in customer sites and the development team does not exit any more. In this case, instead of original developers, other developers or test engineers take a product and test it. The unit testing done by a non-developer, who is not the original developer, would cause some difficulties or cause more cost. In this paper, we tests an open source, JTopas, as a non-developer, with building test models, implementing test codes, and executing test cases. To fit this experiment to practical testing situations, we designed it based on the practices of unit testing, which were surveyed through SPIN(Software Process Improvement Network). This paper analyzes which part of unit testing done by non-developers needs more effort compared to the unit testing done by original developers. And it concludes that Agile Development contributes on reducing the extra effort caused by non-developers, since it implements test codes first before developing source code. That means all the units have already included their own tests code when they are released.
