In the cases of the major cities, high poverty rate of the elderly, immature pension policies, and insufficient market conditions, policies and services for the employment of the elderly decrease the desire for the job participation. It is time to prevent the problems of the elderly, and induce the reachable seniors to participate in social activities. This research provides the location-based, customized job-search service for the elderly in order to actively support the participation in the economic activities of the elderly. The goal of SSJS(Smart Senior Job Search) is to provide the individual elderly with the customized position. It prints the appropriate positions near user location based on the residential area, job classification, and the physical condition, and provides the mash-up of the selectable job range in the unit distance based on the map. This customized service, which enables the seniors to select the type of the jobs based on their physical, mental and life conditions of the seniors, supports the participation in economic activities of the elderly people, and contribute to the expansion of the social job positions for the elderly and the equalization of the local development.

Shipyard design and equipments layout problem, which are directly linked with the productivity of ship production, is an important issue serving as reference data of production plan for later massive production of ships. So far in many cases, design of a shipyard has been relying on the experienced engineers in shipbuilding, resulting in sporadic and poorly organized processes. And thus, economic losses as well as trials and errors in that accord have been pointed out as inevitable problems. This paper extracts a checklist of major elements to fine tune the shipbuilding yard designing process and the input/output data based on the simulation based shipbuilding yard layout designing framework and methodology proposed in existing researches, and executed initial architecture to develop software that integrates all the relevant processes and designing tools. In this course, both user request and design data by the steps are arranged and organized in the proposed layout design template form. In addition, simulation is done based on the parent shipbuilding process planning and scheduling data of the ship product, shipbuilding process and work stage facilities that constitute shipbuilding yard, and design items are verified and optimized with the layout and equipment list showing optimal process planning and scheduling effects. All the contents of this paper are based on simulation based shipbuilding yard layout designing methodology, and initial architecture processes are based on object oriented development methodology and system engineering methods.

Due to the increasing interest in wellness aroused by the aging population and the pursuing feature of active old age, Korean elderly set importance on long life with their healthy condition. Following the change in the paradigm of the medical delivery system from hospital-oriented, treatment-oriented to personal-centered and self-care, Service design application of Smart Healthcare for the elderly became valuable. Smart Healthcare is a healthcare service provided through the fusion of ICT technologies including mobile/wearable devices, IoT, big data, and information technology, and it is utilized to prevent diseases managing abundant health information and living habits. As a methodology for delivering such Smart Healthcare to the elderly, Service design can be adopted. Therefore, this study would like to present the perquisites of Smart Healthcare design for the elderly through analyzing the results from in-depth interview methods between the elderly and medical staff. As a result of this study, guidelines for Service design application of health vulnerability management for the elderly utilizing smart phones were presented. Therefore, this study presented four prerequisites composed of 'high level of supplementation and ethical decision making', 'improvement of inequality in accessibility and experience', 'resolving problems in policy implementation' and 'user-friendliness' for the Smart Healthcare service design for the elderly. Overall, Service design is expected to play an innovative role in improving the quality of life for the elderly through the process of collecting and delivering information on Smart Healthcare centered on the experience of the elderly.

본 연구에서는 축과 베어링으로 구성된 공작기계 주축 설계를 위한 1차원 유한요소 해석을 자동화하기 위한 툴을 개발하였습니다. 객체지향 프로그래밍을 기반으로 하기 때문에, CAD 시스템의 객체를 사용할 수 있습니다. 스핀들 시스템을 정의하기 위한 축의 단면과 베어링 강성과 같은 최소한의 데이터를 입력할 필요가 있으며, 그 데이터를 기반으로 형상 모델을 먼저 만들고, 그리고, 1차원 빔과 스프링 요소로 구성된 유한요소 모델로 변환합니다. 본 툴을 위해서 개발된 사용자 인터페이스는 사용자가 툴과 상호교류할 수 있도록 도와줍니다. 본 툴은 다수의 설계 변경과 그 후에 수행되는 유한요소해석 과정을 자동화함으로써 최소한의 시간과 노력으로 공작기계 주축 시스템의 근사 최적 설계를 발견할 수 있도록 해줍니다.

다양한 응용 분야의 데이터베이스 설계시에 시스템 사용자와 설계자 간의 이해를 증진시키고 올바른 모델링을 위해 개체-관계 모델이 많이 사용되고 있다. 그렇지만 효과적인 구현을 위해 이 개체-관계 모델로 표현된 데이터베이스는 데이터 조작과 표현이 효율적인 객체지향 데이터베이스 모델로 변환되어야 한다. 이를 위해 개체-관계 모델의 모든 개념을 객체지향 모델의 개념으로 의미의 손실없이 변환시키는 방법이 연구되어야 한다. 이 논문은 일반화 상속과 집단화 상속의 개념을 도입하여 개체-관계 모델의 기능을 확장시켰고, 개체-관계 모델의 각 성분을 객체지향 데이터베이스 모델의 성분으로 변환시키는 규칙을 제시하고자 한다. 이 변환 규칙에서 역할에 따른 변환 기법을 제시하고, 이 제시된 변환 규칙을 이용하여 개체-관계 모델에서 객체지향 모델의 스키마로 의미의 손실 없이 변환됨을 예로써 보인다. 제안된 변환 기법은 데이터베이스 설계의 논리적 모델 설계에 활용될 수 있다.

웹 서비스 조합 분야는 단일 서비스를 재사용하여 가치 있는 서비스를 생성하기 위해 등장했으며, 최근에는 차세대 웹 서비스인 시멘틱 웹을 구현하기 위해 IOPE를 기반으로 단순 검색 및 조합 대신에 규칙이나 AI를 통한 검색 및 조합 방법이 제안되고 있다. 또한 보다 효율적인 모듈화를 위해 기존의 객체지향 프로그래밍 방식보다는 관점지향 프로그래밍 방식이 도입되고 있다. 본 논문에서는 시멘틱 웹을 위해 관점지향 프로그래밍(Aspect-Oriented Programming, AOP) 및 리플렉션(Reflection)을 적용한 동적 웹 서비스 조합 및 실행 기법을 설계한다. 제안하는 기법은 웹 서비스의 메타 데이터를 동적으로 획득하기 위해 리플렉션 기법을 사용하고 아울러 동적으로 웹 서비스를 조합하기 위해 AOP 기반 접근방식을 통해 바이트 코드를 생성한다. 또한 리플렉션을 이용한 동적 프록시 객체를 통해 조합된 웹 서비스를 실행하는 방식을 제안한다. 제안하는 기법의 성능 평가를 위해 비즈니스 로직 계층과 사용자 뷰 계층 측면에서 조합된 웹 서비스를 검색하는 것에 대한 실험을 수행한다.

The proliferation of many interactive Topic Detection and Tracking (iTDT) systems has motivated researchers to design systems that can track and detect news better. iTDT focuses on user interaction, user evaluation, and user interfaces. Recently, increasing effort has been devoted to user interfaces to improve TDT systems by investigating not just the user interaction aspect but also user and task oriented evaluation. This study investigates the combination of the bag of words and named entities approaches implemented in the iTDT interface, called Interactive Event Tracking (iEvent), including what TDT tasks these approaches facilitate. iEvent is composed of three components, which are Cluster View (CV), Document View (DV), and Term View (TV). User experiments have been carried out amongst journalists to compare three settings of iEvent: Setup 1 and Setup 2 (baseline setups), and Setup 3 (experimental setup). Setup 1 used bag of words and Setup 2 used named entities, while Setup 3 used a combination of bag of words and named entities. Journalists were asked to perform TDT tasks: Tracking and Detection. Findings revealed that the combination of bag of words and named entities approaches generally facilitated the journalists to perform well in the TDT tasks. This study has confirmed that the combination approach in iTDT is useful and enhanced the effectiveness of users' performance in performing the TDT tasks. It gives suggestions on the features with their approaches which facilitated the journalists in performing the TDT tasks.

This paper reports on the development of the analysis program of the valve train system, IV-TAP. It is essential to verify the stability of the design and to improve the performance of the system. In order to do that effi챠ently, it is required that integrated and interactive simulation analysis program. IV-TAP is developed in the base of the object-oriented, capsulation, modulization, OLE(objected linking and embedding) and variational design theory. So it contain the expandability and flexibility of the structure. In additon to that, it is programed to make the convenient user interface by using the visualization programming. It can support the modification of the valve element as well as the development of the valve system in the beginning. It is expected to reduce the money and effort for design the valve train system.
