  • In this paper an inter-layer protocol, referred to as a Multi-Network Selector (MNS) is proposed for multiband maritime networks. A MNS is located between the data-link layer and the network layer and performs vertical handover when a ship moves another radio network. In order to provide seamless data transfer to different radio networks, the MNS uses received signal strength (RSS) and ship's location information as decision parameters for vertical handover, which can avoid ping-pong effect and reduces handover latency. In addition, we present related issues in order to implement the MNS for a multiband maritime network.

  • The development of Korean textile industry has continued for the early industrialization. But a change in situation of circumstances, textile industry undergoes hard times. To overcome the barrier, therefore, technical development and design innovation are needed to make high value added product. This paper try to put to practical use of the silk weighting process technique(WPT). First, we investigate the technical trend of WPT to summarize the theory, and examine the feasibility of technical development. Second, the application of Graft process to silk textile is examined to know whether it is possible as an practical use. Next, we present the practical way of WPT using MAA monomer through experiment. The results are as follow. 1) Considering the lack of silk yarn. Graft process is appropriate new technique to make the value added product, and fine quality. 2) Studing textile goods, it need inter-displlinary co-work not only fiber engineering scope because textile goods is closely related with fashion industry. 3) MAA monomer used in this paper is more excellent then other monomer because it has good weighting effect and does not harm to the nature of textile. 4) MAA WPT is good for silk textiles of ladies jacket and neck-tie.

  • This study investigates how cognitive and affective conflict affect performance and social outcomes in the new product situation. We examine the corporate, project, and personal characteristics that determine the level of inter-functional conflict between marketing and R&D. From a survey of Korean high-tech companies, we found : (1) time pressure was positively related to cognitive and affective conflict, (2) joint reward systems, interdepartmental connectedness, and years of education were negatively associated to cognitive conflict, (3) while cognitive conflict was positively related to new product creativity and NPD performance, affective conflict was negatively associated to marketing-R&D integration and perceived effectiveness of the relationship, as well as new product creativity and NPD performance.

  • The history of the Palgongsan Fault comprises the growth-fault, the dormant and the strike-slip phases. Dissecting the Palgongsan Granite, the Palgongsan Strike-slip Fault, which is the product of the final phase, sinistrally offset about 5.5 km as shown in the dislocation of the Hasandong Formation. Faulting, sedimentation and igneous activity were inter-related in the early phases of the Palgongsan Fault. Some other faults such as the Dansan Pond Fault and the Hayang Fault have also been discovered, and their some stratigraphic implications and the ages of faulting are discussed. The anomalous development of the Jindong Formation in the study area and the related stratigraphic problems are discussed. It has been confirmed that the Konchonri Formation deposited over the Chaeyaksan Volcanic Formation in spite of the recent doubts on their such stratigraphic relation. The chronological sequence of the volcanisms of the Kyongsang Basin has been summarized.

  • This study is to explore the development of Korean National Emergency Management System. For the study's purpose, the concept of Emergency, Emergency Management and the existing system and related laws of National Emergency Management have been reviewed. In South Korea, the concept of National Emergency Management contains the variety concept of emergency management; safety management, security management, risk management and disaster management etc. and sometimes using them interchangeably. In addition, there are several laws related to emergency management, making different agencies managing inter-related emergency without nationalized coordination and control tower that results in ineffective management of national emergency. This study attempts to clarify the concept of national emergency and to suggest the necessity of National Integrated Emergency Management System(IEMS). Then, it suggests existing system and related laws's integrate for the development of South Korean National Emergency Management System.

  • The specialized textbook library provides resources for textbook publishers and textbook development professionals as well as others in related fields who are committed to the educational development of our country. The textbook library also supports research and education among the faculty and students. But, when examining the reality of the textbook specialized library, analysis concludes that it faces various problems such as state-supported operating budget shortfalls, weakness of public infrastructure, difficulty in collection of textbook-related data, and lack of inter-linked library systems. Thus, this study determined the development direction of the textbook specialized library through the process of literature analysis, case studies, and reflection of expert opinions. In this study, a long-term policy direction of the building and operating of textbook specialized libraries has been proposed as follows: organizing and operating a textbook specialized library, collecting and creating a list of textbook-related information resources, creating information strategy, and constructing specialized content for the textbook specialized library.

  • This paper describes the development of a web-based interference verification system in the mold design process. Although several commercial CAD systems furnish interference verification functions, those systems are very expensive and inadequate to perform collaborative works over the Internet. In this paper, an efficient and precision hybrid interference verification algorithm for the web-based interference verification system over the distributed environment has been studied. The proposed system uses lightweight CAD files produced from the optimally transformed CAD data through ACIS kernel and InterOp. Collaborators related to the development of a new product are able to verify the interference verification over the Internet without commercial CAD systems. The system reduces production cost, errors and lead-time to the market. Validity of the developed system is confirmed through case studies.

  • Disease incidence (DI), pre-emergence damping-off (PDO), days until the first symptom appeared (DUS), disease progress curve (DPC), and area under disease progress curve (AUDPC) were investigated in vivo after sowing ginseng seeds in each of 37 ginseng-cultivated soils which were sampled from 4 regions in Korea. Non linear fitting parameters, A, B, K and M, were estimated from the Richards' function, one of the disease progress models, by using the DI at each day from the bioassay. Inter- and intra-relationships between disease variables and stand-missing rate (SMR) in fields were investigated by using the simple correlation analysis. Disease variables of the root rot were divided into two groups: variables related to disease incidence, e.g., DI, AUDPC and A parameter, and variables related to disease progress, e.g., B, K and M parameters. DI, AUDPC, and DUS had significant correlations with SMR in ginseng fields, and then it showed that the disease development in vivo corresponded with that in fields. Soil samples could be separated into 3 and 4 groups, respectively, on the basis of the principal component 1 (PC1) and the principal component 2 (PC2), which were derived from the principal component analysis (PCA) of Richards' parameters, A, B, K and M. PC1 accounted for B, K and M parameters, and PC2 accounted for A parameter.
