현재 보험범죄는 해마다 증가하고 있으나 정부차원에서 보험범죄를 적발하거나 방지하기 위한 전문조직은 미비한 실정이다. 이러한 보험범죄로 인한 피해는 인명과 국민경제 측면에서 매우 심각한 실정이다. 보험범죄는 보험회사의 경영수지를 악화시키는 것은 물론이고, 보험금의 부정유출로 인해 보험사의 손해율을 악화시킴으로써 보험사 부실의 원인이 될 수 있다. 이는 결국 보험사의 보험료 인상으로 이어져 결국, 보험가입자의 보험료 인상이라는 문제를 야기시킨다. 이러한 이유로 1996년부터 보험회사들은 보상조직 내에 보험사기를 전문적으로 조사하기 위한 보험범죄특별조사팀(Special Investigation Unit, SIU)을 구성하기 시작하였다. 하지만 현재의 SIU는 보험범죄의 예방을 위한 다양한 업무를 효율적으로 수행하기에는 아직 그 인력과 재원이 부족한 수준이다. 따라서 본 연구는 갈수록 심각한 사회문제로 주목받고 있는 보험범죄를 실제 현장에서 담당하고 있는 SIU 구성원을 대상으로 현재의 근무환경과 보험범죄에 대한 일반적 인식이 그들의 직무만족에 미치는 영향에 대하여 알아보았다. 본 연구는 이러한 현장조사 분석을 바탕으로 현재 SIU 구성원들의 보험범죄 인식 및 근무 환경을 분석하고, 직무만족 향상을 통하여 구축할 수 있는 효과적인 보험범죄 대응 방안을 마련하는 데에 목적이 있다.

Nursing staffing is of major interest in hospital management, however, no practical method has been developed. The present study proposed a mathematical model based on the patient classification system for nursing staffing optimization. A few characteristic parameters possibly determined experimentally and/or empirically were introduced followed by systematic calculation of the required number of nurses. An essential concept of the model is the unit work load defined as the amount of nursing work performed on single patient per unit time, where the work load is defined as the number of nursing staffs multiplied by the working hours. The unit work load was considered to vary with the patient classification level as well as the working time during a day, both of which were represented by corresponding parameter values. The number of patients for each class and the number of working hours were multiplied to the unit work load, and added up to obtain the total required work load. As the next step, the averaged number of hours that a nurse could provide per day was formulated considering the degree of nursing practice experience into 3 levels. Finally, the appropriate number of nursing staffs was calculated as the total work load divided by the average working hours per nurse. The present technique has a great advantage that the number of nursing staffs to fulfill the required work load is systematically calculated once the characteristic parameters are appropriately determined, leading to instant and fast evaluation. A practical PC program was also developed to apply the present model to nursing practice.

정부는 2004년부터 원가산정체계를 실적공사비 중심으로 전환하였다. 이러한 실적공사비는 계약단가를 기준으로 산정되며, 현재 10억원 이상의 공공 건설공사에 적용되고 있다. 그러나 대형공사 위주의 평균단가로 구성되어 있는 실적공사비를 10억원 미만의 소규모 건축공사에 직접적으로 반영하게 됨으로써 소규모 건축공사의 실행금액이 계약금액 이상으로 증가되는 경우가 빈번히 발생하고 있다. 뿐만 아니라, 이에 따른 영업이익의 감소로 기업운영 및 생산성 등에 악영향을 미치는 등과 같은 여러 문제들이 야기되고 있다. 따라서 10억원 미만의 소규모 건축공사에 실적공사비를 적용하기 위해서는 사업의 규모 등을 반영할 수 있는 단가보정 방안이 있어야 한다. 이에 본 연구에서는 실적공사비를 10억원 미만의 소규모 건축공사에 적용하는데 발생할 수 있는 단가적용의 문제를 해결하기 위하여 실적단가를 보정할 수 있는 실적공사비 단가보정 모델을 개발하였다. 이 모델은 소규모 건축공사의 생산성과 적정한 이윤을 책정하는데 도움을 줄 수 있으며, 소규모 건설업체의 경영이 악화되는 것을 방지할 수 있을 것으로 판단된다. 그리고 발주처는 예산편성 시 현실성 있는 공사비를 확보할 수 있을 것으로 기대된다.

Vibrational film has been more employed in ear-phones or small type of speakers along with a wide use of portable multi-media equipments such as MP3 and MP4. However, the current hand work production process of diaphragms is inefficient. In this study, a die-and-mold and a single production forming machine are developed, and they result in a multi-production forming machine. The multi-production forming machine consists primarily of a film feeding unit and an unwinding unit. A vacuum suction device provides the film feeding unit, while the unwinding unit is obtained using an appropriate damper. The advantage of the developed single production forming machine is shown according to a proper voice test.

In current complex nature of management with task-structures, a method to reach the enterprise's informationalization success is not common. To satisfy these various requirement, improving the usability of information technology (IT) is a key factor which defining the level of organizational requirement first. Imposing an IT-solution which has excess service of the organization's previous task-environment, procedure and scope is not effective to SME-level unit, which unit could not have a formal organization structure and task structure. SME level informationalization will be success if each function realizes easier on the task-employee's viewpoint. Achieving this objective, a solution provider or department must reflect their work characteristics of nature which has least level of work performing resistance. It is most useful system for SME level unit, if a provider develops single programs which based on task activities, and each program can configure network-linking.

It is important to identify the exact target optical cable that a worker look for when he executes a cable construction work. Until now, An Optical cable identification work has been done by a manual pulling of an optical cable or by the method of using RF signals. But these methods not only consume much time and labor costs but also have a distance limit of the optical cable to identify. In this paper, we propose a method that uses the phase change signal of the optical interferometer to identify an optical cable. With the proposed method the field worker can have an efficient tool to prevent miscutting the optical cable and can also save operating costs.
