한국에서 말라리아는 1993년에 다시 등장했으며, 이후 증감을 반복하며 공간적 변화를 거듭하여 왔다. 지리 공간의 인문·자연·지리적 요인들은 복잡하게 상호작용하여 매개 모기의 생태와 말라리아 발생에 영향을 미친다. 본 연구는 말라리아의 발생 양상을 이해하고 이를 조절하는 데 기여하고자 그 공간적 패턴을 분석하였다. 본 연구는 Getis-Ord의 Gi* 와 평균 중심점을 이용하여 2001년부터 2014년 사이 말라리아 발생의 공간적 분포를 탐색적으로 분석하여, 그 시공간적 변화를 파악하였다. 또한 일반화 포아송 회귀모형을 이용하여 2001년, 2014년 말라리아에 영향을 미치는 인문·환경 요인을 비교·분석하고, 군사분계선으로부터의 거리 변수를 이용하여 그 공간적 자기상관을 설명하고자 하였다. 그 결과, 소 두수, 표준공시지가, 성비, 아파트 비율, 군사분계선 거리, 기후 요소, 논 비율이 말라리아 발생에 영향을 미치는 유의한 변수로 확인되었다.

The purpose of this research was to identify how students used social media during their experience with study abroad programs that focus on social and environmental sustainability. Key research questions included: Did students and program faculty directors perceive social media as beneficial or challenging to program goal? How did social media contribute to the overall learning process? How can this knowledge inform the design and implementation of future study abroad experiences? Surveys were conducted with students participating in three study abroad programs in three countries with varying levels of internet access. We found that most students used social media as a familiar support system to help acclimate to a foreign land, through the formation of cohesive peer groups and establishment of communication channels with family and friends. However, both students and program directors acknowledged the challenges of social media dependency. We conclude that judicious use of social media, when coupled with conscious immersion into the local environment and culture can enhance study abroad programs; and offer suggestions for future program planning.

Much of the data used in the analysis of environmental ecological data is being obtained over time. If the number of time points is small, the data will not be given enough information, so repeated measurements or multiple survey points data should be used to perform a comprehensive analysis. The method used for that case is longitudinal data analysis or mixed model analysis. However, if the amount of information is sufficient due to the large number of time points, repetitive data are not needed and these data are analyzed using time series analysis technique. In particular, with a large number of data points in the current situation, when we want to predict how each variable affects each other, or what trends will be expected in the future, we should analyze the data using time series analysis techniques. In this study, we introduce univariate time series analysis, intervention time series model, transfer function model, and multivariate time series model and review research papers studied in Korea. We also introduce an error correction model, which can be used to analyze environmental ecological data.

한국에서 결핵은 소위 후진국 병으로 인식되어 사라진 질병으로 여겨진다. 그러나 한국은 OECD 가입국 중 결핵 발병률 및 사망률이 가장 높은 국가로 결핵은 여전히 사회적 문제이다. 특히 결핵은 사회적 질병으로서 다양한 사회 ․환경적 요인들이 작용하여 나타나는 질병이기에 이에 대한 연구가 필요하다. 하지만 한국의 결핵 관련 연구는 생의학적 결정 요인 연구에 집중되어, 이외에 발병에 영향을 미칠 수 있는 사회 ․환경적 결정요인 연구는 매우 부족한 실정이다. 이는 결핵 발병의 생의학적 결정 요인과 사회 ․환경적 결정 요인을 통합적으로 분석하고 있는 최근의 세계적 연구 흐름과도 동떨어져 있다. 따라서 본 연구는 2015년 국내 결핵 발병률의 공간적 차이를 확인하고, 아이겐벡터 공간필터링 모형을 이용하여 공간적 차이에 기반한 결핵 발병의 사회 ․환경적 결정요인을 분석해 보고자 한다.

본 연구는 경남지역 야계사방사업지의 적지적소를 판정하기 위해 사방댐 총 526개소와 계류보전시설 총 230개소의 기시공지 및 시공예정지를 대상으로 입지 및 임상, 수문조건을 분석하였다. 사방댐 시공 지과 계류보전시설은 입지환경인자 중 퇴적암, 표고 201∼400m, 경사 21∼30°, 산사태위험등급 2등급 인 곳에 가장 많이 시공되었고, 임상환경인자인 임상, 경급, 영급, 밀도 중 소경급, Ⅲ영급 임분에서만 시공빈도가 유사하였다. 또한 사방댐의 크기 및 개소수를 결정하는 수문환경인자 중 유역면적의 경우 50ha 이하, 수계밀도 2.1∼4.0km/km2, 종장형 수계, 1시간당 최대강수량 61∼90mm, 1일 최대강수량 201∼300mm인 곳에서 가장 많이 시공되었다. 따라서 사방댐 시공지와 계류보전시설지 간의 입지 및 수문조건이 다소 유사한 것으로 추후 야계사방사업을 실시할 경우 산각붕괴 및 침식 발생위험이 높은 지역에 한해서는 사방댐과 계류보전시설의 병행이 가능한 것으로 판단된다.

The present study focuses on the construct of entrepreneurial alertness, investigating the external antecedents of the construct, responding to the call for more research pledged by Tang, Kacmar, and Busenitz (2012). Namely, we examine how receiving feedback, awards and collaboration offers in relation to an individual’s hobby activity influences the development of entrepreneurial alertness dimensions. Additionally, we make a contribution by testing the effect of these external factors in a non-entrepreneurial context of homebrewing communities, that is individuals producing beer at home as a hobby. In line with other form of craft activities, this context has demonstrated a high potential for business start-up development due to the increasing number of new small brewing businesses in North America run by entrepreneurs that were previously homebrewers (Carroll & Swaminathan, 2000). We test our tenets within the complexity theory, where configurations of antecedents are examined in order to gain deeper understanding of the possible outcome (Woodside, 2014), using 213 completed questionnaires. We apply fuzzy-set qualitative comparative analysis (fsQCA, Ragin 2000; 2008) to achieve a holistic overview of the examined interrelationships (Ordanini, Parasuraman & Rubera, 2015). We find that high feedback is a sufficient condition for high scanning and search, association and connection, as well as evaluation and judgement activities of entrepreneurial alertness. Without feedback, people at the hobby stage engage in their leisure activities solely because they like it. However, receiving feedback in relation to their hobby outcomes provides an opportunity for individuals to develop and experience additional motivations beyond enjoyment, where they understand that the hobby could be commercialized and bring monetary rewards. Moreover, we find that an individual receiving low amount of awards but high amount of collaboration offers may also have high entrepreneurial alertness. Since individuals receive rewards related to the excellent performance in their leisure activity, it may not provide any cue for a potential transformation into a business. However, the more collaboration offers people receive, the more likely they get involved in scanning and search, association and connection, and evaluation and judgement activities of entrepreneurial alertness. Therefore, they are likely to conduct additional search, connect bits of available information and evaluate this business opportunity (Gaglio & Winter, 2009). The findings of this study could help entrepreneurs reflect on their decisions and behaviours during the business start-up planning process, and measure their entrepreneurial alertness and the extent of readiness to engage in business venturing.

The previous social welfare system medical treatment, economy, society, etc, failed to guarantee “quality of life,” in various respects. In such a situation, green areas can be devised as an alternative means of directly improving the quality of life. Furthermore, natural resources and ecosystem services are essential elements of environmental welfare that have the purpose of supporting health and quality of life. However, despite the importance of such green space, it is often unavailable and there is a great disparity in its distribution among different regions in urbanized areas where residents are intensively dispersed. Therefore, the present study suggests a plan for reducing the regional imbalances in the green environment by using distributive equality and visual access as indexes, and Dalseo-gu, Daegu Metropolitan City as the subject; the research results are deemed to be sufficient for carrying out the important role of providing the basic data necessary for establishing future environmental welfare policy. An examination of the analysis results are as follows. First, Gamsam-dong was revealed to need additional green areas; out of the 167 spaces that were regarded as possible for green biotope construction, 48 spaces appeared possible for additional green biotope construction. However, only 10 spaces were assessed as having the potential for actual green biotope construction, excluding the spaces affected by local green environments. Moreover, given a concern with green equality, a final two were deducted as additional green spaces. The present study is significant in that it accomplishes visual accessibility analysis in terms of visual quality, including the effects of aesthetic enjoyment along with distributive equality from green biotopes; the relevant subfactors include green area supply and demand when constructing additional green biotopes to realize a city with improved environmental welfare. However, the present study is limited in terms of failing to consider the green biotope of local administrative districts affecting the target area of the study because it analyzes equality and disconnected green areas for selecting additional green biotope spaces using Dalseo-gu Daegu as its subject.

In the blast work inevitably exists a vacant space between drilling hole wall and explosive. So it cause an blast inefficiency called on a decoupling effect. In this study, For enhancing the detonation efficiency and reducing the environmental problem(vibration, noise, etc.), water is used to fill the vacant space. Water filling has many advantages such as efficiency, low price and workability. In the comparison analysis the field test is carried out. It result on an aspect of the effectiveness and safety. The result measured in the field is as follows; First, the water tube blast reduces the vibration by 16.5% and lessen the noise by 1% comparing to general blast. Secondly, water tube blast makes a separation distance shortened by maximum 15m. Thirdly, in the case that the same quantities of explosive are used, the amount of crushing per hole increased by about 12.8% in water blast method. The quantity of the explosive is reduced by about 11.4% comparing with general blast.

Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots’ psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots’ psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots’ cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots’ psychological effects.

This study was carried out to establish the management plan by surveying and analyzing the environmental and ecological characteristics of Milletia japonica habitat, Mt. Moak, Jeonbuk, Korea.

Global warming has pressured companies to put a greater emphasis on environment management which allows them to reduce environmental impact and costs of their operations. In Korea, the coal-fired power plants take a large account of electricity generation at 31.7% of the total electricity usage in 2014. Thus, environmental impact of coal-fired power plants is significant. This paper illustrated how to compute environmental impact and costs in electricity generation at a coal-fired power plant using MFCA methodology. Compared to the traditional accounting, an advantage of MFCA is to provide information on electricity generation costs and environmental wastes incurring throughout the production process of electricity. Based on MFCA, the coal-fired power plant was able to reduce production cost of electricity by 52.3%, and environmental wastes by 47.7%. As a result, MFCA seemed to be an effective tool in environmental management for power plants.

The world energy crisis and the universal interest in comfort buildings are not only leading the thriving Passive House and Nearly Zero Energy House strategies but also encouraging the development of higher performance HVAC systems and alternative energy sources for occupants and sensible energy consumption. However, household appliances have been used to control the indoor environment such as humidifiers, dehumidifiers and air cleaners are became popular, occupants have come to rely on these appliances heavily and are overusing energy on indoor environment manage easily and quickly. In addition, the intense air tightness of current residential buildings makes possible to reduce harmful outdoor conditions but has made the indoor environment isolated from the outdoors. As well, climate change due to global warming and the urban heat island effect have broken the natural bond between humans and the environment. As high-rise, air tight buildings have become the most common residential building type in South Korea, occupants in high-rise residential buildings inevitably lose the chances to have the natural environment by the change of season to feel the warm sunlights of spring and the dry leafy smell on an autumn breeze. In this sense, regional weather data was analysed to establish comfort residential building strategies that commune with nature and o
