Based on the results of preceding researches that the uncertainty perceived by the private security guards about their roles exerts direct effects on the business performance of the security industry, it needs to preferentially examine the degree of authority that the private security guards have. The suitability of the psychological empowerment criteria for measuring this for private security guards, however, has not yet been established up to the present, so it can be said that the validity of the information has not yet been established. Accordingly, as the psychological empowerment criteria of private security guards, this research examined the suitability of items, reliability of items, the level of difficulty of items, and the item goodness of fit from the viewpoint of the appropriateness of category of responses, and it is summarized as follows. First, in the self-determinism factor of the psychological empowerment criteria, Item 11 was found to be an unsuitable item, so it is proper that Item 11 should be deleted when examining the psychological empowerment of private security guards from now on. Second, the item reliability of the psychological empowerment criteria was high, so the consistency of the results is shown even if the data are collected from the other private security guards. Third, they feel that it is hard to respond to Item 12 while they perceive that Item 1 is the easiest, and the level of items of the psychological empowerment criteria is evenly distributed. Fourth, it was established that the 5-point categories of the psychological empowerment criteria were suitable to the private security guards.

The purpose of this study is to investigate the factors that influence the intention to continuously use the RPA program used in the financial industry for those working in the financial industry. In particular, the purpose of this study is to understand the will to accept and the perception of acceptance conflict by considering the characteristics of individuals in the relationship between work and information technology. As a result of the study, it can be confirmed that the RPA system based on intelligent process automation including artificial intelligence should be further strengthened in the transformation of a digitalized enterprise rather than the RPA based on simple task automation that is currently most used. In general, the phenomenon of cognitive dissonance was prominent for the adoption of new technology, but the phenomenon of cognitive dissonance did not appear for the continued use of RPA in the financial industry. Able to know. In the future in the financial industry, it is thought that the change in the labor organization will be accelerated as the suitability of repetitive tasks and technologies is increased.

A survey was conducted to study perception and attitudes of health workers towards health center's activities and organization of health services, from August 15 to September 30, 1994. The study population was 310 health workers engaged in seven urban health centers in Taegu City area. A questionnaire method was used to collect data and response rate was 81.3 percent or 252 respondents. The following are summaries of findings: Profiles of study population: Health workers were predominantly female(62.3%); had college education(60.3%); and held medical and nursing positions(39.6%), technicians(30.6%) and public health/administrative positions(29.8%). Perceptions on health center's resources: Slightly more than a half(51.1%) of respondents expressed that physical facilities of the centers are inadequate; equipments needed are short(39.0%); human resource is inadequate(44.8%); and health budget allocated is insufficient(38.5%) to support the performance of health center's activities. Decentralization and health services: The majority revealed that the decentralization of government system would affect the future activities of health centers(51.9%) which may have to change. However, only one quarter of respondents(25.4%) seemed to view the decentralization positively as they expect that it would help perform health activities more effectively. The majority of the respondents(78.6%) insisted that the function and organization of the urban health centers should be changed. Target workload and job satisfaction: A large proportion (43.3%) of respondents felt that present target setting systems for various health activities are unrealistic in terms of community needs and health center's situation while only 11.1 percent responded it positively; the majority(57.5%) revealed that they need further training in professional fields to perform their job more effectively; more than one third(35.7%) expressed that they enjoy their professional autonomy in their job performance; and a considerable proportion (39.3%) said they are satisfied with their present work. Regarding the personnel management, more worker(47.3%) perceived it negatively than positive(11.5%) as most of workers seemed to think the personnel management practiced at the health centers is not fair or justly done. Health services rendered: Among health services rendered, health workers perceived the following services are most successfully delivered; they are, in order of importance, Tb control, curative services, and maternal and child health care. Such areas as health education, oral health, environmental sanitation, and integrated health services are needed to be strengthening. Regarding the community attitudes towards health workers, 41.3 percent of respondents think they are trusted by the community they serve. New areas of concern identified which must be included in future activities of health centers are, in order of priority, health care of elderly population, home health care, rehabilitation services, and such chronic diseases control programs as diabetes, hypertension, school health and mental health care. In conclusion, the study revealed that health workers seemed to have more negative perceptions and attitudes than positive ones towards organization and management of health services and activities performed by the urban health centers where they are engaged. More specifically, the majority of health workers studied revealed to have the following areas of health center's organization and management inadequate or insufficient to support effective performance of their health activities: Namely, physical facilities and equipments required are inadequate; human and financial resources are insufficient; personnel management is unsatisfactory; setting of service target system is unrealistic in terms of the community needs. However, respondents displayed a number of positive perceptions, particularly to those areas as further training needs and implementation of decentralization of government system which will bring more autonomy of local government as they perceived these change would bring the necessary changes to future activities of the health center. They also displayed positive perceptions in their job autonomy and have job satisfactions.

본 연구는 OLS 및 변수선택법에 의해 통계학적 모형의 매개변수를 산정하여 모형의 적용성을 입증하고 하천 주요지점에 대한 홍수위 예측을 통해 홍수예보 및 예측 업무에 기여코자하는데 연구목적이 있다. 다중선형회귀모형을 구성하기 위한 독립변수는 예보지점의 수위/유출량 자료와 상류지점의 수위/유출량 자료, 그리고 유역의 선행 평균강우량 등의 자료를 독립변수로 하여 통계학적 홍수예측을 위한 다중선형 회귀모형을 각각 구성하여 적합성 여부를 판단하였다. 매개변수 산정은 OLS(Ordinary least square root method)와 변수선택(Stepwise)방법에 의해 산정하였으며, 중랑천 유역의 2002년부터 2005년까지의 수문사상 16개를 선정하여 모형에 적용한 결과 두 매개변수 산정방법 모두 30분에서 90분 예측은 상대적으로 정확한 결과를 나타내었으며, OLS 및 변수선택법에 의한 매개변수 산정결과 변수선택법에 의한 방법이 OLS 방법보다는 상관성이나 효율지수면에서 조금 더 정확한 값을 나타내고 있으나 독립변수의 일관성을 감안한다면 변수선택법보다는 OLS방법에 의한 매개변수 산정이 타당할 것으로 사료된다. 기존의 홍수예보 업무에 활용되고 있는 수문학적 홍수예측 모형인 저류함수법의 여러 매개변수 조정에 의한 홍수위 예측 방법보다는 비교적 간단한 통계적 방법에 의한 홍수위 예측 방법으로 홍수예보의 선행시간 확보가 필수적인 중랑천과 같이 유역면적이 작은 중소하천에서의 홍수예보 업무에 효과적으로 이용 가능할 것으로 사료된다.

Business Process Management (BPM) System is a software system to support an efficient execution, control and management of business processes. The system automates complex business processes and manages them effectively to raise productivity. Traditional commercial systems mainly focus on automating processes and do not have methods for enhancing process performances and task performer's efficiency. Therefore, there is room for enhancement of task performers' productivities and efficiency of business processes. In this paper, we propose a new method of executing business processes more efficiently in that a whole process is scheduled considering the degree of participants' workload. The method allows managing the largest constraints among constituent resources of the process. This method is based on the DBR (Drum-Buffer-Rope) in TOC (Theory of Constraints) concepts. We first consider the differences between business process models and DBR application models, and then develop the modified drum, buffer and rope. This leads us to develop BP-DBR (Business Process-DBR) that can control the proper size of task performers' work list and arrival rate of process instances. Use of BP-DBR improves the efficiency of the whole process as well as participants' working condition. We then carry out a set of simulation experiments and compare the effectiveness of our approach with that of the scheduling techniques used in existing systems.

The information generated from large and complex construction projects transfer and evolve in long-term business cycle. Therefore, while there is any problem, such as delay, the cause of the problem might relate to the previous business process rather than where it arises. However, for complex project players and business relationships, it is unsuitable to search an information flow using traditional retrieval methods. This research addresses a relationship-based information search system to analyze the information flow in large-scale and complex construction projects. First, we identified the components of the information retrieval system customizing for a large-scale complex construction projects, and then developed the inference algorithm which define the relationship between business processes. For the validation, we applied the system on a business information system of urban regeneration projects and suggested some application using information flow retrieval system for project players and project managers. Using the system, players are easy to prepare for their work process and managers can define the causal flow of the problem.

최근 기업에서는 사무생산성을 향상시키기 위하여 조직의 특성에 맞는 사무자동화 기기를 도입하여 운영하고 있다. 조직에 따라 OA추진 방식이 다양하므로 OA 추진현황을 분석하여 성공적으로 OA를 추진할 수 있는 방안을 제시할 수 있다면 의미가 있다고 하겠다. 본 연구에서는 현재 우리나라의 OA현황을 조사분석하여 기업이 OA를 추진하는데 가장 적합한 추진방향을 제시하는 것을 목적으로 한다. 따라서 개략적인 OA추진운영 현황을 파악한 후 추진특성별 운영방식과 추진운영별 도입성과를 확인하여 OA도입성과를 극대화하는 추진방향을 제시하고자 한다. 연구조사를 위해 OA 추진 업체와 OA 관련 종사자를 대상으로 우편 설문조사를 실시하여 자료를 수집하였다. 연구결과는 대기업의 경우 OA가 일정수준에까지 도달하였으며, 대부분 장단기계획을 수립한 후에 OA를 추진하고 있으나 투자비용 제한, 개발인력 부족, OA기기에 대한 저항감과 같은 문제점을 안고 있는 실정이므로 이러한 문제점을 해결할 수 있는 방안을 마련하여 OA를 활성화하는 것이 바람직하다. OA실무자는 단순반복업무를 담당하고 있어 업무처리와 관리방식 개선과 같은 근본적인 업무를 거의 하지 못하고 있다. OA도입성과를 극대화하여 성공적으로 OA를 추진운영하기 위해서는 장기계획을 수립하여 추진하고 실무자의 의견을 반영하여 중대형 컴퓨터와 연계활용해야 하는 것으로 나타났다.

최근에는 기업에서 처리되는 업무 형태가 그 절차도 더욱 많아지고 절차 간 흐름도 복잡해지고 있다. 여러 기업들이 관여되는, 이른바 대규모화되어 가고 있다. 워크플로우 시스템은 업무를 이루고 있는 단위 업무 처리에 적합하도록 객체 단위로 설계되어 있다. 적용 분야와 경우에 따라서는 이러한 생성되어 수행중인 객체들이 수만에서 수백만개가 여러 기업에 분산되어 존재하기도 한다. 따라서 기존의 단일서버-클라이언트 형태의 관리 도구로는 이러한 대규모 시스템을 지원하기에는 서버구조가 매우 비효율적이고, 서비스에도 많은 문제점을 안고 있다. 본 논문에서는 기업의 관리 모듈을 규모에 따라 워크플로우 엔진에 의존적으로 분산된 형태로 데이터와 기능들을 분산 배치시키고 메인 관리기에서 통합하여 관리함으로써 운용 서버의 부하를 줄이고, 가용성을 높일 수 있는 방안들을 추출하여 설계하고 구현하였다.
