  • The leisure boat industry has the potential to become a high-value-added industry in the future. Recently, a study on Korean high-speed leisure boats for fishing was conducted. This study suggests a product configuration model-based shipbuilding cost estimation method for determining the type of leisure boat suitable for mass production, as part of a research for productivity improvement. The suggested estimation method based on the analysis of the leisure boat process and generic YWBS can calculate quantitative and concrete data. By using this method, the cost of building the catamaran-type design ship can be reduced by 17 times, compared to that of the monohull-type mother ship. This implies that the final design of the Korean high-speed leisure boat for fishing will have a competitive price at the actual production stage.

  • To develop a sailing yacht successfully, systematic engineering information is required including technologies from various companies and know-how about sailing yacht. The engineering information about sailing yacht has a complex and extensive structure. Therefore, a robust and high-level of management system is needed to manage the information. In this paper, we design and propose Generic-YWBS (Generic-Yacht Work Breakdown Structure), a work breakdown structure for sailing yachts. The Generic-YWBS is aimed at constructing sailing yachts and contains contents about product- and process-oriented information of sailing yachts. In addition, the Generic-YWBS plays an important role in managing the engineering information as a basic schema of database and system architecture. The Generic-YWBS is derived from fundamental WBS design processes and various rules about sailing yachts, for example, ISAF (International Sailing Federation) equipment rule and IRC rating rule, and a generic structure concept is applied for flexibility. The Generic-YWBS is applicable for various purposes. We designed a detailed code system in order to apply the Generic-YWBS to contents management system. The series of activities are realized through a web-based RIA(Rich Internet Application) program. This program manages the YWBS structure in an XML schema, and the Generic-YWBS management application offers a customizing function to be adapted in the field.

  • Objective : The purpose of this study is to establish the domain for assessment of feeding disorder with cerebral palsy. In addition, it is to develop item on feeding assessment for feeding disorder on children with cerebral palsy Methods : Factors to be included in the assessment of feeding disorders in children with cerebral palsy based on the ICF classification criteria constituted the assessment domain through literature review. Results : Assessment items of feeding disorders in children with cerebral palsy were categorized into 6 domains. These were systematized through expert advice, and through the first and second Delphi surveys, nine middle categories, 32 sub-categories, and 76 items were confirmed. Conclusions : The results of this study are useful for occupational therapists who want to check the current feeding function and activity level during therapeutic interventions for children with cerebral palsy who have feeding disorders.

  • 오늘날 특정 유역에서의 수문현상 및 수문순환에 대한 분석을 위한 연구가 활발히 진행되고 있다. 이를 위해서는 수문자료의 관측은 반드시 수반되어야 하며, 관측자료의 품질관리 및 원시자료의 관리 등이 요구되고 있는 실정이다. 관측된 수문자료의 품질관리라 함은 자료의 신뢰도 분석과 자료의 보완의 두 과정을 포함한다. 여기서, 신뢰도 분석이라 함은 자료 속에 포함된 불확실성을 판별하는 작업을 의미하며, 자료의 불확실성은 위에서 언급된 자료의 불충분 및 불안정을 제외한 부정확, 불일관성에서 비롯된다. 자료의 보완이라 함은 자료의 신뢰도 분석을 통하여 자료 속에 포함된 불확실한 성분들을 찾아내고, 이를 제거한 후 완전한 자료로 대체하고, 자료가 결측된 경우 공백을 연결함으로써 자료의 완전성을 유지하거나 또는 불충분한 자료를 확장하는 일련의 보완작업이라고 정의한다. 자료의 품질을 결정하는 주요 인자는 크게 관측소 관리의 하드웨어적인 측면과 자료 분석의 소프트웨어적인 측면이 있다. 하드웨어적인 측면에서의 수문자료 품질관리를 위해서 본 과제에서는 현장에 설치된 수위계, 강우량계의 센서 등에 대한 장비를 점검하고, 현장실측을 통해 지속적으로 측정값을 보정해주는 역할을 수행하고 있으며, 소프트웨어적인 측면에서 수문자료의 품질관리를 위해서는 수문자료의 수집 단계부터 시작하여 데이터베이스 저장, 필터링, 통계분석, 웹 및 C/S(Client Server)를 통한 배포 등의 일련의 자료 처리 과정을 수행할 수 있는 수문자료관리 프로그램을 웹 시스템과 C/S로 분류하여 정의내릴 수 있다. 본 연구에서는 수문자료의 관리자 입장에서의 보다 효율적이고 체계적으로 자료를 관리하고 분석하기 위한 방안으로 수문자료관리시스템(Hydrologic Data Aquisition and Management System, HDAMS)을 개발하였다. 이 시스템은 안양천 유역에서 시범 적용하고 있으며, 범용성을 전제로 개발되었다. 또한 수문자료 관리 프로그램의 DB 구조 및 DB 자료를 활용한 다양한 분석기능은 갖도록 설계하였으며 계획된 데이터베이스 구조를 바탕으로 계측기 인터페이스와 사용자 인터페이스, 데이터베이스 간의 연동이 원활히 이루어지도록 개발하고자 한다.

  • Due to the changes in market place, new business types(e.g. e-business} have been rapidly emerged and increased. However, those new business types have not much been emerged in port and logistics related industries, and adoption rate of e-business in this area is very low, compared to other industries. Thus, to promote e-business in this area, many policies have been studied. However, most of previous studies have not been based on industrial structure, and results of these studies have mostly been case by case. Further, there have been no research based on the related theories. As a result, despite many of research and project for shipping and port related e-business, prominent achievements in this area have never to be presented. For these reasons, it am be stated that, first of all, basic studies related to new business types in shipping and port are needed, and then, various policies based on results of those basic studies should be discussed. The aim of this study is to classify business types existed (or expected) in a port related industry, ship bunkering. This taxonomy was based on theories related to business layer(BL) and value chain(VC), and these BL and VC combination enabled to acquire all possible business types.
