Due to the International Maritime Organization's (IMO) environmental regulations on NOx and SOx, LNG-fueled eco-friendly ships are gaining attention worldwide, and various eco-friendly ships are being proposed and demanded for conversion to eco-friendly ships in Korea, as the eco-friendly ship law has recently been enforced. In this study, the initial basic design was performed to convert an existing Marine Gas Oil (MGO) fueled ship into an LNG-DF propulsion ship, targeting medium-sized ship, to select the fuel tank capacity and main dimensions and appropriate fuel ratio between the two fuels. In particular, Sustainable basic design method considering environmental impact were proposed by performing a Life Cycle Assessment (LCA) throughout the design process, and various design options were compared and analyzed to meet different design conditions by applying them.

In this study, we analyzed t he design condition for appropriate design factor at geothermal system design documents. It is intended to provide the proper information of geothermal system design condition when construct new building, designer can use design conditions more efficiently. Therefore, it is possible to plan for domestic geothermal system, through utilization at design element, to provide as a good information that can predict the approximate underground condition. Thus, provided the basic design conditions that can predict the capacity of the geothermal system. It will be the first step to solve the problem.

The purpose of this study is developing basic module of kitchen furniture design by considering the dimensions of work-surfaces, such as the size of worktable and the length of the kitchen furniture based on the physical size of a human scale and the behavior in the kitchen and the size of goods. In conclusion, this study develops a basic module of the kitchen furniture and suggests the new dimension for the kitchen based on the human scale and demand for the kitchen goods thus, it is expected to use it as a basic data for the kitchen space study and kitchen furniture industry.

The purpose of this study was to examine a unique characteristic of the colors of the costumes in Korean basic culture in the aim of seeking Five-elements color found in Korean civilian's costume culture. The scope of Korean basic culture was 32 items specified as an import intangible cultural asset in the side of religion and art for the majority of the Korean people. Within these limits, the colors of the dress, accessories, instruments were extracted by comparing with the naked eye in NCS Color System. The result of this investigation was that Red was yellowish red and high chromatic and deep tone within 4area. Blue was purplish blue and high chromatic and deep tone within 4area, similarly Red. Yellow was pure yellow and high chromatic and bright tone within 3area. Red and Blue in Korean basic culture were more primary color and more high brightness than Korean traditional colors. Religion and art fer Korean civilian revealing the Korean basic culture reflected impending real-life of Korean civilian who intend to overcome their desperate reality at using Five-elements color in their costume.

Recently domestic companies have been needed to securing competitive techniques due to increasing orders of plant industries in the oversea construction market. Although domestic engineering companies have been assessed competitive in the field of detail design, their high value-added basic design have evaluated uncompetitive. To manage efficiently various contents which occurred in works of design steps, the management method must be built. In this study, we have found the contents which required to management through the definition of main works and analysis of characteristics in the step of basic design. Then, we have suggested to Contents Classification System which reflected of work flows and relations among stakeholders. Proposed Contents Classification System will help us when requiring the proper documents, drawings, sheets and other information.

With the recent acceleration of industrial technologies and active research, wearable robot technologies have been applied to various fields. To study the utility of wearable robots, basic research on kinetic mechanisms of the human body, bio-signal analysis, and system control are essential. In this study, we investigated the basic structure of a wearable system and the operating principles of a driving mechanism. The control system and supporting structure, which comprise the driving mechanism, were designed and manufactured. Motion and load analyses were performed simultaneously for the design of the kinematic drive, and the driving mechanism was constructed by analyzing walking motion. The operating conditions of the cylinder were verified by stride via driving experiments. Further, the accuracy and responsiveness of the system were confirmed by comparison with actual motion, and the system safety was validated by applying loads.

In this paper, we describe the basic design of the preventive diagnostic expert system for 765kV substation equipments. This expert system is developed to use expert system development tool and the main subjects considered are 765kV class power transformer and GIS. We basically designed the total structure of expert system and considered database interface methods, inference engine and control, triggering system which compose expert system.

The study is to provide basic data on improving costume's fitting by developing physical integrated Basic Bodice Block's development for body types of adult women, which is based on setting up body-type information per truncus as fundamental of adult women's top product manufacture in being ready for Mass Customization era. Also, after review on the objectivity and accuracy of fitting information by real wear and virtual wear experiment on body types, not only 3D virtual clothing system was used as way of information provider of Clothing product, but also provided as basic data in order to use effectively on portion of clothing passion in responding to trend of Mass customization in advance. The consequence of the study is as followings. After analyzing significance differences per items on real and virtual wear evaluation, bowed type of type 1 had significance differences on waist measurement and hip circumference in back and side, which would be knowing as not integrated with costume, affecting form of human body according to virtual wear system bended on back region. Also, in side evaluation, every types except straight body type of type 3 appeared significant differences. In virtual wear evaluation, costume's expression with side body types were not similar to real wear until now except straight body types. It would be improvement things from 3D virtual wear system in advance.

This paper presents critical steps in building client/server application with UML and Visual Basic, which are derived from the implementation case of a typical order processing system. To begin with, we briefly review the software architecture, the diagrams and the object-oriened building process in the UML. In the inception phase, it is critical to define the project charter, to draw use case diagrams, and to construct a preliminary architecture of the application. In the elaboration phase, it is critical to identify classes to be displayed in the class diagram, to develop user interface prototypes for each use case, to construct sequence diagram for each use case, and finally to design an implementation architecture. Steps to construct implementation architecture are given. In the construction phase, it is critical to design both the database and components. Steps to design these components are described in detail. Additionally the way to create the Internet interface is suggested.

In this paper, the water cooling method among the forced coolant cooling methods is considered to be applied to the 110kW-class IPMSM for railway vehicles. First, basic thermal property analysis of the IPMSM is conducted using the three-dimensional thermal equivalent network method. Then, based on the results of the basic thermal property analysis, some design requirements for the water cooling jacket are deduced and a basic design of the water cooling jacket is carried out. Finally, thermal equivalent circuit of the water cooling jacket is attached to the IPMSM's 3D thermal equivalent network and then, the basic thermal and effectiveness analysis are conducted for the case of applying the water cooling jacket to the IPMSM. In the future, the thermal variation trends inside the IPMSM by the application of the water cooling jacket is expected to be quickly and easily predicted even at the design step of the railway traction motor.
