산지재해는 1차적으로 산지사면에서 산사태가 발생되어 2차적으로 계류를 따라 토석류로 이동 및 확산되면서 산지 하부지역의 시설지와 주거지에 피해를 발생시킨다. 따라서 본 연구는 전라북도 지역의 토석류 발생지 79개소를 조사 대상으로 현장조사를 통한 발생 길이에 영향을 미치는 인자를 구명하고, 수량화이론(I)을 이용하여 발생 길이에 대한 각 인자의 기여도 분석을 통해 예방적인 측면에서 전라북도 지역 내 토석류 발생 위험지역에 대한 예측기준을 작성하였다. 토석류의 발생 길이에 영향을 미치는 인자는 모암(화성암), 횡단사면(복합사면), 입목 흉고직경(6cm 이하), 표고(501m 이상), 발생위치(산록) 등이었다. 각 인자의 범위를 추정한 결과, 모암(0.5633)이 가장 높게 나타나 전라북도 지역의 토석류 발생 위험도에 큰 영향을 미치는 것으로 추정되었으며, 다음으로는 횡단사면(0.4565), 사면위치(0.3568), 흉고직경(0.3274), 표고(0.3052)순으로 나타났다. 전라북도 지역 산지에서 토석류 발생 위험도 판정식을 기준으로 5개 인자의 카테고리별 점수를 계산한 추정치 범위는 0점에서 2.0092점 사이에 분포하였다. 중앙값인 1.0046점을 기준으로 토석류 위험도 예측을 위한 등급을 분류한 결과 Ⅰ등급은 1.5070 이상, Ⅱ등급 1.0047 ∼ 1.5069, Ⅲ등급 0.5023 ∼ 1.0046, IV등급 0.5022 이하로 나타났고, Ⅰ등급과 Ⅱ등급에서 토석류 발생비율이 76%로서 비교적 높은 적중률을 보였다. 따라서 본 판정표는 전라북도의 산지에서 지역의 위험 비탈면에 있어서 토석류 발생 위험도 판정에 유용하게 활용할 수 있을 것으로 판단된다.

PURPOSES: The purpose of this study is to develop an epidemic model considering interregional trips. METHODS : We developed the SIR-T model, which is an epidemic model of infectious diseases based on a metapopulation model considering the interactions between population groups. This model can consider the characteristics of the modes. A simulation was performed using this model to analyze the progress of the Middle East Respiratory Syndrome (MERS) in Korea, in 2015. RESULTS: The simulation results show that the spread of infectious diseases through passenger cars was the fastest and had the largest spread range. In the case of public transportation systems such as intercity buses, public railways, and high-speed railways, infectious diseases spread primarily at major terminal facilities and traffic facilities. CONCLUSIONS: The epidemic model of infectious diseases considering the interregional trips proposed in this study can be used as the base data for prevention strategy planning. However, a significant limitation is the lack of discussion on simulation parameter settings in this study, and further discussions are required in future studies.

본 연구는 2011년과 2013년 중소기업기술통계 조사에 응답한 4,000개 기업 중 본사가 부산에 소재한 중소기업(5인 이상 300인 미만) 481개사를 대상으로 기업의 혁신전략에 따른 민간 연구개발 투자에 미치는 영향요인을 살펴보았다. 기업의 혁신전략과 관련해서는 R&D 포트폴리오, 연구개발조직 및 인력, 조직의 혁신전략 방향 설정자로서의 CEO 역할을 독립변수로 제시하였다. 또한, 산업을 제조업 기술수준별 4개 그룹과 지식서비스업 등 총 5개로 구분하고, 종속변수 민간 연구개발 투자비에 대한 영향을 선형 회귀 분석하였다. 이에 따른 분석 결과는 기업의 혁신전략 중 복합적인 R&D포트폴리오, 체계적인 연구조직 보유, 연구인력 증가는 모두 민간 연구개발비 투자에 정(+)의 영향을 미친다. 이를 산업별로 구분 하여 분석하여도 연구개발 조직과 연구인력 보유가 유의미한 영향요인으로 나타났다. 위의 결과를 살펴볼 때, 지역 중소기업의 민간 연구개발투자를 활성화하기 위해서는 다양한 R&D 포트폴리오를 갖추고 체계적인 연구개발 조직과 충분한 연구인력을 확보한 기업을 중심으로 R&D 투자가 확대할 수 있도록 산업별 특성을 고려한 정책 지원이 필요하다고 할 수 있다.

PURPOSES: This paper develops a new stochastic approach to analyze the pavement-vehicle interaction model with a certain roughness and elasticity for the pavement foundation, thereby accommodating the deflection of the pavement, and to identify the road subsidence zone represented with a sudden changes in the elasticity of the foundation. METHODS: In the proposed model, a quarter-car model was combined with a filtered white noise model of road roughness and a two-layer foundation (Euler-Bernoulli beam for the top surface and Winkler foundation to represent the sub-structure soil). An augmented state-space model for the subsystems was formulated. Then, because the input is White noise and the system is represented as a single system, the Lyapunov equation governing the covariance of the system’s response was solved to obtain a structurally weak zone index (WZI). RESULTS: The results showed that the WZI from the pavement-vehicle interaction model is sensitive enough to identify road subsidence. In particular, the WZI rapidly changed with a small change in foundation elasticity, indicating that the model has the potential to detect road subsidence in the early stage. CONCLUSIONS: Beacause of the simplicity of the calculation, the proposed approach has potential applications in managing road conditions while a vehicle travels along the road and detecting road subsidence using a device with an on-board computational capability, such as a smart phone.

PURPOSES: This study aimed to develop a proactive anti-icing system for driving zones at risk during winter. METHODS: An electric low power potable anti-icing system, operated with a battery and solar cell, was designed and fabricated. Potassium acetate was used as the anti-icing chemical. The developed anti-icing system was tested in the laboratory in advance to confirm its function. Potassium acetate was also tested both in the laboratory and outdoor (exposed to the sun) conditions. The anti-icing system was set up on the road for field testing. RESULTS: The 195 m spread distance of the anti-icing system was verified in the field test. CONCLUSIONS: The anti-icing system developed for safe driving on the road will be cost-effective and economical during installation and maintenance compared with currently used snow melting systems on vulnerable driving zones.

The purpose of this study was to determine changes in neighborhoods due to the development of residential districts around Jangchungdan(獎忠壇) altar in Seoul from the 1920s to the 1930s. In the Joseon Dynasty, this area was a protected and sacred area to honor the spirit. The reputation of the area, however, turned into the place to play and take a rest and neighborhoods around Jangchungdan altar were developed as high-grade residential districts with the impression of suburbs during the Japanese colonial period. Residential districts were formed with the destruction of the Hanyang City Wall and the privatization of nation-owned forest, which were physical and symbolic boundaries of Seoul in the Joseon Dynasty.

This study aimed to develop unique, local “food tourism” products by finding specialized items that combine tourist attractions, such as folklore or hot springs. Traditional ingredients were analyzed with ancient texts for the methods of research. A brand image was made possible utilizing hot spring lore and other regional stories. The tofu products were produced using local specialty beans. Products, such as tofu residue cake and willow bean tea, were made with the tofu residue. After the products were completed, the sensory test began at the local tourist attraction. Asan City’s food tourism product willow tofu was made with beans that were given as compensation for building the Onyang temporary palace according to the Annals of the Joseon Dynasty and the willow tree that appears in Sunshin Lee’s anecdotes. After the preference test between normal tofu and willow-extract tofu was conducted to measure the product potential of willow tofu, among the sample extracts, 0.04% of the willow extract showed a significant preference. The hot spring tofu-residue cake was baked using tofu residue and vegetable olive oil to substitute for animal oil, such as butter, or margarine. After the sensory test targeting the adults was conducted, both products displayed significant product potential with average scores above 5.0. Willow tree bark, which hasantioxidation and anti-inflammatory effects without a bitter taste or strong smell, was proven to bean appropriate ingredient for leached tea. The nutty flavor of leached tea was enhanced by roasted green kernel black beans and willow tree bark. The sensory test showed that the leached tea and tofu received a high preference rating on both color and flavor.

This study aimed to analyze the profitability and economic feasibility of hairtail trolling line gear that was developed for the last 3 years (2015-2017). The new fishing gear technology development was accomplished to solve the current problem of fishermen shortage in hairtail targeting fisheries in Jeju region. Results indicated that the profitability of developed hairtail trolling line fishery was estimated to be 36.1 % which would be higher than that of other hairtail targeting fisheries in Jeju region. In addition, as an economic feasibility, the net present value and the internal rate of return of a 20-year cash inflow and outflow were evaluated to be 400.2 million won and 66.9 %, respectively. However, sensitivity analyses of main variables showed that the profitability and economic feasibility would be vulnerable to catch amount and market condition changes.

This study examined the current state of the representative support projects for each government that have been promoted to foster local industries. We have identified the changes and focus areas of the supporting industries in the biotechnology and medical industry sectors selected by each region. As a result, we found that most of the support for the bio and medical industry is concentrated in the industrial biotechnology field. We found that continued investment by governments and local governments had an impact on the growth of the biomedical industry In addition, an analysis of the results for 15 years (2002~ 2006) on sales and net profit (net loss) showed that productivity and growth were affected.

PURPOSES: The goal of this study is the development of roundabout accident models for urban and non-urban areas. METHODS: This study performed a comparative analysis of the regional factors affecting accidents. Traffic accident data were collected for the period 2010~2014 from the TAAS data set of the Road Traffic Authority. To develop the roundabout accident models, the Poisson and negative binomial regression models were used. A total of 25 explanatory variables such as geometry, and traffic volume were used. RESULTS : The key findings are as follows: First, it was found that the null hypotheses that the number of accidents is the same should be rejected. Second, three Poisson regression accident models, which are statistically significant (p2 of 0.154 and 0.385) were developed. Third, it was noted that although the common variable of the three models (models Ⅰ~Ⅲ) is the number of entry lanes, the specific variables are entry lane width, roundabout sign, number of circulatory roadways, splitter island, number of exit lanes, exit lane width, number of approach roads, and truck apron. CONCLUSIONS: The results of this study can provide suggestive countermeasures for decreasing the number of roundabout accidents.

The purpose of this study is to review and establish the three concepts of upcycling, zero-waste fashion design, and regional sustainability through a review of domestic and international case studies. Furthermore, it will provide the theoretical basis for using upcycling as a regional sustainability practice to create zero-waste fashion design. To conduct an empirical study, we systematized the stages of the survey on waste resources in Changsin-dong, the sourcing and utilization of waste resources, the design-planning stage, and the co-production with pattern and sewing masters as a suggested practice for regional sustainability. Through this study, we propose the possibility of regional sustainability by developing and sharing the method of zero-waste fashion design. The conclusion of the study as follows: First, upcycling fashion designs can be extended to a regional sustainability practice by taking the characteristics of social design into account. Second, by providing a design development process and methodology suitable for regional sustainability application, it is helpful to revitalize regional upcycling fashion brands and communities by providing data for upcycled fashion branding. Third, as part of the revitalization project for the Changshin and Soongin areas that started in 2014, using the region’s economic, cultural, and environmental characteristics to make and sell high-value, upcycled fashion products will contribute to social and economic achievements and aid in solving regional problems.
