The purpose of this paper is to design and implement a Computer Assisted Personal Interviewing (CAPI) system for Panel Survey of Employment for the Disabled (PSED) using Blaise software developed by Statistics Netherlands which is a powerful and flexible system used for computer-assisted survey processing. CAPI system for PSED is consisted of three parts, which are survey management program, electronic questionnaire program, and postprocessing program. These programs are constructed with modular approach and are integrated into CAPI system. The developed software is highlighted in its reusability which results in the improved efficiency and reduced cost of software maintenance. CAPI system for PSED proved its effectiveness in carrying out the survey by guaranteeing correctness of survey data, improved timeliness of survey, easy reforming the questionnaires, easy control on the interviewers, and rapid data processing in spite of the complexity of PSED.

본 논문에서는 글로벌 표준화 시스템으로의 확장성을 고려하고 자동화 처리 개념을 적용한 한국형 리서치 시스템을 개발한다. 리서치 시스템의 기반이 되어지는 설문조사의 종류에는 전화조사, 온라인조사, 면접조사 등의 조사방법이 있으며 현재 대부분의 프로세스가 수동적 작업화 상태에서 데이터를 수집 검증하여 비효율적인 상태로 운영되어지고 있다. 현재 일부 기업들이 자체 프로그램의 개발을 시도하고 있지만 전문 프로그래머들의 리서치 업무에 대한 업무분석 및 이해 부족과 외부 개발 용역에 대한 고비용성으로 대부분 시스템 구축에 완성도가 낮아 개발시스템 운영에 실패를 하고 있는 실정이다. 부가적으로 개별 기업들이 초기 개발비용을 감수하지 않기 위해 외국산 리서치 솔루션을 구입하면서 높은 제품 비용과 로열티 비용 부담으로 인하여 기업 리서치 시스템 구축을 통한 효율화를 이루지 못하는 실정이다. 본 논문에서는 산학협력 연구개발로 1회의 설문입력 과정으로 개별적인 전화조사, 온라인조사, 면접조사를 동시에 가능하도록 통합하는 자동화 시스템과 일반 사용자까지 쉽고, 빠르게 설문지를 입력하고 진행하여 컴퓨터에 의한 정확한 데이터를 신속하게 고객에게 전달 할 수 있는 서비스 체제를 구축하고 설문조사의 최종 단계인 데이터 분석 및 가공에 필요한 기본적인 분석, 통계 기능 제공과 오피스 프로그램 및 통계 프로그램인 SPSS프로그램과 호환성을 주어 리서치 운영 프로세스의 개선을 목적으로 한국형 자동화 리서치 솔루션을 개발한다.

There are three types of survey research system, telephone surveys, online surveys, interviews and so on. Currently most of the survey data have been verified by hand-collecting state in korea. Semi-automated research systems, some companies are using imported from abroad. This paper is the study on the design and implementation of linked research system for global standardization. The system is optimized through customizing for local conditions, as well as professionals for telephone surveys, online surveys, interviews even a normal user can enter the questionnaire easily and quickly. The result data is passed to the customer quickly and accurately. In particular, this system is based on automatic data input and collected provides best efficient analysis and statistics. Office programs and advanced statistical program SPSS is compatible with the maximum benefits for proposed system. Additionally, to achieve the import substitution effect through localization and to propose a global standard the proposed system is designed and implemented.

This article presents strengths of Computer-Assisted Personal Interviewing(CAPI) in social surveys with complicated questionnaires, from examples of a pilot and the first year surveys of the Korean Longitudinal Study of Ageing(KLoSA). This study focuses on how to improve the quality of data by using CAPI and finds five strengths among others. First of all, CAPI can contribute to reducing response errors by structuring the logic and path of questionnaires, setting a response range, and maintaining response consistency. Second, CAPI enhances convenience of interviewing by allowing customized questions and automatic calculation and scoring. It also allows the 'help' function. Third, its random arrangement of questions prevents response order effect and/or questions order effect. Fourth, CAPI can raise the response rate by reducing item non-responses. Fifth, it makes it easy monitoring interviewing, thus helps supervising interviewers and modifying questionnaires when necessary. These merits of CAPI contribute to reducing possible errors in the process of interviewing, therefore improve the data quality.

As intellectual terror threats increase, we feel the limit in coping with those threats and the things we do are placing traditional X-ray machines & ETD and increasing aviation security staffs. In fact, even if air transportation system is the fast and most efficient transportation methods, it is true that there are many inconveniences to endure due to terror threats. In the name of security, even if we make a lot of efforts and time to screen both good-natured passengers, baggage, cargo and suspicious passengers, it is impossible to screen perfectly and it is not an efficient methods. Therefore, we introduce profiling system that reduce the effort to screen good-natured passengers but focus on screening dangerous passengers and baggages. Profiling system strengthens aviation security, using the concept "Selection & Concentration". Israel started to introduce manual profiling system in aviation security, which is interviewing suspicious passengers and it has been used in crime investigation since 1960. And it has been upgraded and diversified to CAPPS(Computer Assisted Passenger Screening Program) and SPOT(Screening Passenger by Observation). So, this theses is to study on the concept & kind of profiling and profiling methods adopted in airlines. Also it presents the method of introduction of profiling system in Korea and the necessity of making law on it.

Workplace Panel Survey(WPS) is the representative panel survey of workplace in Korea. WPS was newly sampled in 2005 and is to be used for the subsequent biennial survey. The main survey is divided into a questionnaire for human resources(HR) manager, a questionnaire for labor relations manager and a questionnaire for representatives of unions. The population of WPS 2005 included workplaces across the country with 30 or more employees. The WPS 2005 was composed of 1,905 workplaces including 290 workplaces in the public sector. The sample was selected by the stratified random sampling. Weighting process for the survey data was introduced to compensate for differential sampling and non-response rates. Personal interviews were conducted using the Computer Assisted Personal Interviewing(CAPI) system during visits by interviewers, along with survey via mail and e-mail concerning employment and financial issues. The CPAI system introduced for the WPS 2005 can by used for automatical detection for errors and inconsistencies which may occur during the survey process. The CAPI system played an important part in enhancing the reliability of the survey data.
