2015년 기업생멸 행정통계에 따르면, 우리나라의 최근 5년 동안('2010~2014년) 연평균 창업은 77만개, 폐업은 69만개인 것으로 나타났다. 지난 2015년 한해에만 개인사업자로 106만8313명이 창업을 하고 73만9420명이 폐업을 했다. 이는 하루 평균 3000명이 창업을 하고 2000명이 문을 닫는 셈이다. 실패를 경험한 기업인들은 여러 가지 심리적, 경제적 어려움에 직면하게 된다고 연구 보고되고 있다. 이같은 결과는 사업실패를 경험한 기업인들에 대한 케어의 필요성을 보여준다. 지난 2010년부터 정부가 실패기업인들에 대한 재기지원사업에 나서고는 있으나 재창업지원제도의 효과성에 대해서는 보장하기 어려운 상태다. 일각에서는 재창업지원이 양적인면에서는 활성화됐으나 질적으로는 아직 미흡하다고 지적이 나오고 있다. 이같은 상황에 착안하여 본 연구는 사업실패를 경험한 기업인들이 겪게되는 심리적 특성과 재기를 하고자 할 때 방해요소로 작용하는 감정요인에 초점을 맞추고자 한다. 따라서 선행연구를 통해 사업실패를 경험한 기업인들의 감정메카니즘을 규명한 모델(건강신념 모델:Health Belief Model)을 적용한 창업실패관련 개인평가와 사업실패경험(재무적 손실, 비재무적 손실)이 재창업의도에 어떠한 영향을 미치는지 규명하고자 한다. 감정요인인 창업실패관련 개인평가는 지각된 심각성, 지각된 취약성, 지각된 장애로 구성했다. 또 창업실패관련 개인평가와 재창업의도 사이, 사업실패경험과 재창업의도 사이에 재창업지원정책, 창업자기효능감이 각각 조절작용을 하는지 유의미한 관계성을 알아보고자한다. 연구 대상은 정부 재창업지원 프로그램을 진행하고 있는 중소기업진흥공단, 서울산업진흥원, 재도전지원센터등 기관의 재창업지원을 받은 기업인을 대상으로 설문을 실시하여 이들이 재창업지원서비스를 받기 전과 후에 대한 측정을 통해 실증분석을 하려고 한다.이 연구가 설정한 가설이 맞을 경우, 시사점으로는 정부의 재창업지원 프로그램의 효과성에 대한 검증이 될 것이다. 또 창업실패관련 감정메카니즘 규명으로 사업실패 기업인들의 재기를 도울 수 있는 재창업지원정책의 고도화가 가능해 질 것으로 판단된다.

Many visually handicapped people face difficulties with using libraries. Public libraries are thus required to meet the need of visually handicapped people. Public libraries should guarantee the visually handicapped the right to use appropriate services. If so, the visually handicapped can improve their life quality by decreasing information gap and increasing information comprehension or accessibility. This study is designed to analyze how visually handicapped people can use public libraries. Based on the analysis, this study can provide actual suggestions to improve opportunities for the visually handicapped to use libraries. Data are collected from visually handicapped people who are the members of Suseong Public Library, Daegu, Korea. In specific, this study can analyze various characteristics(i.e., information needs, selection and use behavior of information sources, difficulties and gaps to access information, use behavior and service satisfaction of public library) regarding their library use by telephone interviews.

This study was a quasi-experimental study of nonequivalent control group pretest-posttest design to investigate the effect of rhythmic dance movement training on the physical and psychological functions of the elderly. The data were collected from November, 2001 to February, 2002. The subjects for this study were 34 elderly who was over 65 years old and was living in J city. The elderly selected for this study were: free from heart and pulmonary disease and not regular exercise. The rhythmic dance movement training in watching video tape was rhythmic dance movement and education and supportive care. The rhythmic dance movement was 40-60 intensity, 8 weeks' period, three times a week, 60 minutes a day. The data were analysed by $X^2$-test, paired t-test and unpaired t-test and ANCOVA through SAS/PC program. The results of the study were as follows: 1. There was insignificant difference in the gait length experimental and control group. 2. There was significant difference in the gait speed between the two groups. 3. There was significant difference in the dynamic valance between the two groups. 4. There was no significant difference in the depression between the two groups. 5. There was no significant difference in the Quality of life between the two groups. As shown above, the results of the 8 weeks' rhythmic movement program for the elderly produced positive effects on gait speed, dynamic valance. And this program was expected that it was more effective in different intervention period, verified program. Also it was needed follow study.

At present, local limestone mines with large opening employ auxiliary fans for workplace ventilation which have been used in coal mines with much smaller airways. Considering the low static pressure loss in the large-opening mines, high pressure auxiliary fans face serious economical limitations mainly due to their excessive capacity. The optimal fan selected for the ventilation in large-opening working places should supply air quantity enough for maintaining safe environment and keep its operating cost as low as possible. This study focuses on the development of a low pressure auxiliary fan designed to have smaller range of the static head but to have more potential for higher ventilation and energy efficiency. The flow characteristics of high and low pressure auxiliary fans were theoretical as well as experimentally investigated to assess the ventilation efficiency in term of environmental and economical aspects. Moreover, the low pressure fan was tested in two limestone mine sites with small and large cross-sectional areas for evaluating its ventilation efficiency. Results from this study can be applied to improve the economy and efficiency of auxiliary fan for ensuring better air quality and work environment management.

In high speed communication networks, the determination of a transmission rate is critical for the stability of a closed-loop network system with the congestion control scheme. In ATM networks, the available bit rate (ABR) service is based on a feedback mechanism, i.e., the network status is transferred to the ABR source by a resource management (RM) cell. RM cells contain the traffic information of the downstream nodes for the traffic rate control. However, the traffic status of the downstream nodes can not be directly transferred to the source node in the IP based networks. In this paper, a new rate-based congestion control scheme using an exponential weighted moving average algorithm is proposed to build an efficient feedback control law for congestion avoidance in high speed communication networks. The proposed congestion control scheme assures the stability of switch buffers and higher link utilization of the network. Moreover, we note that the proposed congestion scheme can flexibly work along with the increasing number of input sources in the network, which results in an improved scalability.

In geographic routing for wireless sensor networks, sources need the location of sinks destined for delivering their data packets. Most of the existing geographic routing protocols merely assume that the sources can get the locations of sinks by some location service. How source nodes find out the location of sinks is not easy. In this paper, we propose a sink location dissemination scheme in geographic routing for wireless sensor networks. In this scheme, a source node and a sink node send sink location announcement and query messages along two paths respectively by geographic routing. The node located on the crossing point of the two paths informs the source about the sink location. Then the source can send data packet to the sink by geographic routing. How to guarantee that these two paths have at least one crossing point in any irregular profile of sensor network is the challenge of this paper Simulation results show that our protocol is significantly superior to other protocols in terms of energy consumption and control overhead.

The purpose of this study is to analyze the data on the medical personnel education system and license scheme and provide the basic material for an enhanced qualification system. In China, dental education reform has been underway with a view to providing an inclusive basic medical service package to the whole country by 2020. It is also estimated that the number of Korean dental medicine students in China would be fewer. And most of them desire to get a job in China after acquiring the Chinese license, suggesting little prospect of a massive inflow into Korea in the near future. In Japan, students are required to complete a clinical training program for over 1 year after receiving licenses to become an independent practitioner. But they can apply for the Korean preliminary examination without this post-graduation process. For this reason, the quality issue in license effectiveness review has been seriously discussed. It is deemed desirable to limit the Korean accreditation to Japanese graduates from the dental schools certified by the Japanese dental accreditation body.
