  • The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.

  • Workaholism refers to a state in which work is the center of self, a state in which other life other than work is deemed worthless, and a state in which one feels that his or her life ends when things get lost. There are concerns that South Korea's work-centered institutions, cultures and long-time labor practices expose workers to workaholism. This study identifies the prevalence of workaholism and its risk factors among workers using a representative sample from Korean Labor and Income Panel Study. The results of empirical analysis of the wide range of workaholism showed that 7.0% of Korean workers were work-addicts. Male, workers working long hours, daily workers, employers, the self-employed were more likely to be work-addicts. Those who think that workload is high beyond regular working hours are more likely to be work-addicts. These results were also confirmed by regression analysis. It suggests that policies to shorten working hours and strengthen job and income stability can reduce the risk of workaholism and balance between work and life.

  • 연료전지는 환경에 친화적인 새로운 에너지기기로서, 업무$\cdot$가정용 전원, 자동차 등의 이동전원, 전자기기용 전원 등 많은 분야에 보급이 기대되고 있다. 그 중에서도 고체고분자 연료전지(이하 ''PEFC''라 함)는, 전해질이 고체로 취급하기 쉽고, 더욱이 동작온도가 실온(室溫)에 가까우며 값이 싸고 소용량화$\cdot$운전유연성이 기대되어, 산$\cdot$$\cdot$연에서 개발이 활발히 추진되고 있다. PEFC 전원의 실용화는, 가정용으로 대표되는 소용랑 코제너레이션 전원으로 먼저 시작될 것으로 생각된다. 구체적으로는, 1kW 출력수준의 코제너레이션 전원 겸 급탕기(給湯器)를 가정에 설치하여 배열(背熱)을 유효 이용함으로써 연료비와 $CO_2$ 배출량을 경감하는 것이다. 여기서는, 이러한 가정용 전원에 대하여 우선 첫째로 전원 운용에 관련된 계산$\cdot$검토를 실시하고 연료비/$CO_2$ 배출량의 삭감효과를 조사했다. 그 결과에 의하면, 예상했던 대로 도입효과가 크게 기대되는 한편, 그 효과는 연료단가와 운전 상황에 따라서도 크게 좌우된다. 어떠한 환경에서도 확실하게 메리트가 있도록 전원의 가일층의 성능향상이 요망된다. 그 외에, 전원의 용량과 부분부하에 대한 검토가 중요하다. 또한, 시스템 시험에서는, 1kW 전원을 시험$\cdot$제작하여 성능시험, 코스트분석을 실시했다. 그 결과 배열회수와 전지/직류교환부의 성능으로 시장도입시의 목표에 가까운 것을 알 수 있었다. 한편 저(低)코스트화에 관해서는, 시스템을 간소하게 하는 기술을 개발중에 있다. 연료전지기술은 앞으로의 사회에 매우 중요하며, 보다 좋은 사회의 실현을 위해 개발에 계속 진력해 나갈 것이다.

  • This paper demonstrates the design and development of asset management systems suitable for the universities full of very various kind of assets. Universities consists of many departments, which have a multiplicity of many experimental. It is very difficult to record and manage assets with hands. In addition, the equipments are moving freely from one lab to another inside the school, which means it is tough to find the location of the assets and so some stuffs that are given lack attention are likely to disappear. So, these things occurring frequently in the university asset management environment should be considered in the design and embodiment of the asset management system. In the proposed system, location recognition of the assets is realized based on a route tracking method, so it is possible to detect the loss of the high priced assets and entrance, export, and lending of them are controlled efficiently. The system is likely to reduce the load of a manager responsible for asset management, because configured to decrease interventions of the manager in overall asset management process. Especially, the proposed system and implementation method will be suitable for small and medium-scale asset management, path tracking, history management.
