Purpose: This study was designed to determine the correlation between faster response time and functional activities of brain regions during cognitive time management. Methods: Twelve healthy subjects participated in this experiment. Subjects performed the serial reaction time task (SRTT), which was designed by the Superlab program, during fMRI scanning. When the 'asterisk' appeared in the 4 partition spaces on the monitor, the subject had to press the correct response button as soon as possible. Results: fMRI results showed activation of the left primary sensorimotor cortex, both premotor areas, the supplementary motor area, posterior parietal cortex and cerebellum. There were significant correlations, from moderate to strong, between faster reaction time and BOLD signal intensity in activated areas. Conclusion: These results suggest that motor skill learning to be needed cognitive time management is associated with greater activation of large scale sensorimotor networks.

최근 집중호우로 인한 산사태, 구미 불산 누출사고 등 국민의 인명과 재산에 막대한 손실을 입히는 중대재난이 계속 발생하고 있지만, 이에 대한 대처가 불충분하여 재난으로부터 안전한 사회에 대한 국민의 요구가 한층 증대되고 있다. 본 논문은 재난관리 전문가 양성을 통한 방재교육역량 강화를 위해 방재부문의 교육 컨텐츠 체계 정립의 핵심기반을 마련함을 목적으로 한다. 이를 위해 우선 수요예측에 의한 교육과정 및 교육과목을 설계하였으며 이를 기초로 하여 재난 현장대비 및 대응 중심의 교육과목을 설계하였다.

Aging of the fire organizations, typical disaster response agencies also will be in serious problems with aging society. It is expected that the ratio of more than fifties will reach 31~40% after 10~15 years in Seoul fire organization. This Aging of firefighters can bring about a serious problem in disaster and safety management, since firefighters require robust fitness and healthy bodies in disaster situations. In this study, after the analysis of aging status and trend of firefighters in Seoul, I have an empirical analysis about the impact this aging has on organization effectiveness and QA. As a result, the increase of the elderly reduced organization effectiveness and QA. In addition, in the group consisting of less than 50, it is expected to increase the organization's effectiveness and QA activities through field activity to improve the professional skills with age, but could not be confirmed. In the group consisting of more than fifties, it was found that aging had a significant negative impact on organizational effectiveness and QA activities as factors, including physical deterioration by aging.

In this paper, we first introduce a general architecture of an energy management system in a home area network based on a smart grid. Then, we propose an efficient scheduling method for home power usage. The home gateway (HG) receives the demand response (DR) information indicating the real-time electricity price, which is transferred to an energy management controller (EMC). Referring to the DR, the EMC achieves an optimal power scheduling scheme, which is delivered to each electric appliance by the HG. Accordingly, all appliances in the home operate automatically in the most cost-effective way possible. In our research, to avoid the high peak-to-average ratio (PAR) of power, we combine the real-time pricing model with the inclining block rate model. By adopting this combined pricing model, our proposed power scheduling method effectively reduces both the electricity cost and the PAR, ultimately strengthening the stability of the entire electricity system.

The purpose of this study was to categorize customers types in accordance with current shop masters' perception of difficult customers and to identify their responding techniques and know-hows in dealing with those customers in detail, a qualitative study is carried out by conducting thorough interviews with the shop masters. The interview contained questions on occupational hold-ups of shop masters, types of hard-to-handle customers, techniques in handling difficult customers, their know-hows in customer managements and what they perceived as the qualities of a shop master. T The results were as follows: 1) Customers who are perceived as difficult by shop masters are categorized into six types, making unreasonable demands, pointing out product defects, disregarding salespersons, making no purchase after testing products, having no personality and having no response. 2) Responding techniques for difficult customers were categorized into three types, 'active response', 'standby' and 'polite refusal'. 3)The result from the question on know-hows of shop masters in customer management can be divided into 4 groups, providing special treatment or information, building one-to-one relationship with the customer, suggesting garments in accordance with the customer's taste and providing friendly customer service. 4) For the question on perceived qualities as a shop master, individual quality, customer management capacity, work experience and occupational knowledge were answered.

촉진 활동과 관련된 보상 프로그램의 효과는 단기적 성과에 집중되거나 일시적인 재구매를 유도하는 한계를 지니고 있다. 이에 본 연구는 불만족 보상 연구의 확장을 위해 보상방식이 소비자의 반응회복에 미치는 영향에 있어 보상시기와 보상강도의 상호작용 효과를 중심으로 검증하였다. 본 연구의 목적은 첫째, 보상방식인 경제적, 비경제적 그리고 결합보상이 소비자의 인지적 반응회복과 감정적 반응회복에 미치는 영향의 차이를 검증하는 데에 있다. 둘째, 보상방식에 따른 소비자의 반응회복 효과에 있어 보상시기와 보상강도의 조절적 역할을 확인하는 데에 있다. 연구의 설계를 위해 3X2X2의 피험자 간 완전 요인설계를 이용하였다. 주요 연구 결과 첫째, 보상방식에 따라 소비자의 반응회복에 미치는 영향의 차이가 있었다. 둘째, 보상방식이 소비자의 반응회복에 미치는 영향은 보상시기에 따라 차이가 있었다. 셋째, 보상방식이 소비자의 반응회복에 미치는 영향은 보상강도에 따라 차이가 있었으며, 소비자 반응 회복정도는 결합보상에서 영향력이 가장 큰 것을 확인하였다. 본 연구는 일반적인 보상 프로그램에서 다루어지는 보상 시기를 소비자들의 불만족 상황에 새롭게 적용시키는 것에 의의를 두고 있으며, 본 연구를 통해 선행 연구들의 실증분석 결과를 지지하고 그 역할을 여러 각도에서 확장시키고자 하였다.

재난은 점차 복합, 대형화되고 있다. 이러한 재난 발생 시에는 기관 간 상호협업을 통해 신속하게 대응해야한다. 하지만 우리나라는 재난 대응 시 각 분야(기관)별로 지휘체계를 분리해서 운영하고 있어 통합적인 재난대응에 한계가 있다. 따라서 본 연구에서는 재난유형 및 규모에 관계없이 적용 가능한 '한국형 재난현장 통합대응 표준체계'를 개발하였다. 다수기관들이 공통적으로 사용 가능한 표준편제, 표준행동요령(SOP), 표준용어를 개발하였으며, 표준체계를 실현하기 위한 법/제도적 뒷받침의 필요성을 제시하였다. 통합대응 표준체계의 활용을 통해 재난현장의 일원화된 지휘/통제, 기관들의 대응 업무 명확화, 원활한 의사소통이 가능해지며, 재난대응 및 수습을 신속하게 진행할 수 있을 것으로 기대된다.

This paper presents an incentive system to reduce response time from a supplier. The incentive system is expressed as a contract between an assembler and a supplier who have a long-term relationship. We produce the optimal payment scheme and expected total cost, when the assembler is farsighted. We show that the farsighted assembler obtains higher effort level from the supplier than the myopic assembler. We also show that the expected total cost of the farsighted assembler is smaller in the long run, although it is initially higher than that of the myopic assembler.

Although numerous distributed database design models and solution algorithms have been developed, very few have been validated. Validation is critical to the successful application of such models to distributed database design. In this paper, we develop a simulation system for distributed database design. We then analyze and validate an average response time model using simulation. The simulation results demonstrate that the average response time model is reasonably accurate.

When a question in a sample survey is sensitive or highly personal, respondents may prefer not to give truthful answers. To eliminate the resulting evasive answer bias Warner suggested a randomized response model. In this paper, a modification of Warner's method is presented and compared with Warner's method. The relation between this modified method and an unrelated question method is also discussed.
