  • Recently with the rapid development of data communication products and service industry, the system on behalf of users for multimedia services such as VoD(Video on Demand), Teleshopping are at the height of development, However, if the new style products and services do not conform to the international standard, the products will come to lose the competitive power in the market. Therefore, it is essential to have conformance testing considered the properties of related protocol for the interoperability of the products and services. As a systematic and efficient conformance testing method of new products in respect of the main protocol of DAVIC(Digital Audio Visual Council) standard, this paper presents the protocol test methodology and architecture ; a single protocol stack an the related protocol stacks testing.

  • Purpose: The study attempted to find family perception differences between abused children and normal children by Kinetic Family Drawing. Method: The subjects of the study consisted of two groups, 143 abused who were in the upper 25th percentile, and 150 normal who were in the lower 25th percentile. Collected Kinetic Family Drawings were divided into five dimensions such as actions, human figure characteristics, dynamics, styles and symbols, and they was analyzed with SPSS/WIN 10.0. Results: In the perception about their family in action dimension, their family in figure characteristics dimension, their family in dynamics dimensions, and their family in symbols dimension, there is a sharp contrast between the two groups. Conclusion: Putting these results together, abused children feel lower self-esteem and feel more sense of alienation in their family than normal children do. In addition, abused children perceive their parents as negative and aggressive people.

  • The old house at No'eun-ri, located in Hongseong-gun Hongbuk-myeon of the Chungcheong Nam-do province, really seems like the old house of late Seong Sam-mun who died in 1456. The original structure of the house seems to have been symmetrical, in terms of its left and right sides, and the females' chamber(Anchae) as well as the guest quarters(Haeng'rang-chae) would have featured a Matbae(맞배) fashion. The flank chamber and corridor would have displayed a multi-storied shape, and people would have been able to traverse the inside of the house all the way to the second story of the residence. We can see such shapes and dispositions from other 'ㅁ'-shaped houses - found in Chungnam and Gyeongbuk regions - which are now considered as distinct characteristics of certain residences constructed before the war with the Japanese in the 1590s, confirmed from extant vestiges and historical records of that time period. It can be concluded that the old house at No'eun-ri does harbor the traits and elements that resembled the upper class residences of the Joseon dynasty's early half period.

  • Silicon carbide ceramics are used for oxidation resistive coating films due to their excellent properties like high strength, good oxidation resistance, and good abrasion resistance, but they have poor formability and are prepared by vapor process which is complicated, costly, and sometimes hazardous. In this study, preparation of silicon carbide coating film by liquid process using polymer precursor was attempted. Coating film was prepared by dip coating on substrate followed by heat treatment in argon at $1200^{\circ}C$. By changing the dipping speed, the thickness was controlled. The effects of plasticizer, binder, or fiber addition on suppression of crack generation in the polymer and ceramic films were examined. It was found that fiber additives was effective for suppressing crack generation.

  • In order to obtain a good result in Arthroscopic ACL Reconstruction by immediate postoperative physical therapy, sufficient analgesia was needed. This study analyzes the analgesic effect of the intra-articular injection with ketorolac, Morphine together with bupivacaine in 80 male patients who had Arthroscopic ACL Reconstruction. On completion of the surgery under spinal anesthesia, the knee was injected with 30ml of 0.25% bupivacaine. Each of the study group received ketorolac and/or morphine, either through parenteral or intra-articular. Total amount of the drug used by Patient Controlled Analgesia(PCA) and Visual Analgesia Scale(VAS) for pain were measured and analyzed. The group which received intra-articular ketorolac or Morphine had a better analgesic effect than other group which received none. The group which received both did not do better in analgesic effect. Intra-articular infusion with either ketorolac or Morphine improved postoperative analgesia in Arthroscopic ACL Reconstruction surgery. However, combined injection did not offer more advantage.

  • To deliver new products to market in a due time, companies often develop their products with numerous partners distributed around the world. Internet technologies can provide a cheap and efficient basis of collaborative product development among distributed partners. This paper provides a framework and its product database model that can support consistent product data during collaborative product development. This framework consists of four components for representing consistent product structure: the product configuration, assembly structure, multiple representations and engineering changes. A product database model realizing the framework is designed and implemented as a system that supports collaborative works in the areas of product design and technical publication. The system enables participating designers and technical publishers to complete their tasks with shared and consistent product data. It also manages the propagation of engineering changes among different representations for individual participants. The Web technologies introduced in this system enable participants to easily access and operate shared product data in a standardized and distributed computing environment.

  • Internet technology opens up another domain for building future CAD/CAM environment. The environment will be global, network-centric, and spatially distributed. In this paper, we present a new approach to network-centric virtual prototyping (NetVP) in a distributed design environment. The presented approach combines the current virtual assembly modeling and analysis technique with distributed computing and communication technology fur supporting virtual prototyping activities over the network. This paper focuses on interoperability, shape representation, and geometric processing for distributed virtual prototyping. STEP standard and CORBA-based interfaces allow the bi-directional communication between the CAD model and virtual prototyping model, which makes it possible to solve the problems of interoperability, heterogeneity of platforms, and data sharing. STEP AP203 and AP214 are utilized as a means of transferring and sharing product models. In addition, Attributed Abstracted B-rep (AAB) is introduced as 3D shape abstraction for transparent and efficient transmission of 3D models and for the maintenance of naming consistency between CAD models and virtual prototyping models over the network.

  • There is a problem to be solved for improvement of durability and safety supervision. When you do the waterproofing and anticorrosive work of main concrete from the design stage, the material and method of construction need to be correctly applied to appropriate circumstance conditions. Epoxy have mostly been used for concrete water tank structure. Lately, lots of subjects on adaption of polyurea resin waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with another waterproofs in this study. Performance evaluation items include the adherence performance, the imprint of seal performance, temperature dependence performance, promotion weatherizing ability, inner chemical performance, drinking water eruptive performance. Through the experiment analysis, we found that the polyurea resin waterproofing membrane is dominantly superior to other waterproofs. According to this study, we suggest the polyurea resin waterproofing membrane as a new waterproofing material for concrete structure.

  • An antibacterial component was isolated from the roots of evening primrose(Oenothera odorata Jacquin). The component was purified by repeated preparative TLC of the chloroform-extract with solvent system of toluene(7):ethyl acetate(4):formic acid(O.8). NMR spectrum indicated that it is a steroid compound containing radical(-C=C-C=0) and aromatic structures. Its antibacterial activity against strains of the genus Streptococcus was relatively high, the MIC value was 50 acccording to the Hoechst Manual-345, as compared with the other genera such as Staphylococcus and Escherichia.
