Current initial rock stress state is one of the key factors required to evaluate the stability and failure around an excavated opening and its importance increases as the construction depth become deeper and the scale of the rock structure become larger. In this paper, the study was performed to evaluate the characteristics of the regional stress state at Chuncheon-Yanggu mountainous region, the East-North part of Kyeonggi Massif. Forty nine field stress measurements in 9 boreholes were conducted at the depth from 20 m to 290 m by hydraulic fracturing method. The fracturing tracing works were carried out by acoustic televiewer scanning. The study results revealed that the different intial rock stress states presented at different formation rock type and the excessive horizontal stress state with stress ratio(K) close to 3.0 was measured at the depth of 200 m and deeper in the intrusive unite body of the study area. The results from the investigation of excessive horizontal stress and its effect on failure mode showed that there exist several points where the localized excessive horizontal stresses are big enough to potentially induce brittle failures around the future openings greater than 100 m in depth within the granite body of the study area.

지금까지 우리나라에서는 도시하수, 공장폐수 등의 점오염원에 국한하여 중점적으로 수질관리를 실행하여 부분적으로 효과를 얻을 수 있었으나, 하천과 호소의 수질은 크게 향상되지 않고 있다. 이는 급속한 도시화와 산업발달로 토지개발이 가속화되고 대지, 도로, 주차장 등 불투수층 면적이 늘어남에 따라 비점오염원에 의한 하천, 호소의 수질영향도가 커지고 있기 때문이다. 인구증가로 인해 물 사용량 뿐만 아니라 이에 따라 배출되는 오염원의 종류 및 오염부하량 역시 함께 증가하고 있다. 장래의 수질관리 성공여부는 비점오염원의 효율적인 관리여부가 큰 변수로 작용할 것으로 본다. 따라서 공공수역의 수질관리를 위해서는 토지이용과 지역특성을 고려한 비점오염원 부하량의 합리적인 조사, 오염 부하량 절감을 위한 관리기술의 개발, 비점오염원 관리정책의 개발 및 수질모형을 이용한 정확한 수질예측 등이 필요하다. 따라서 본 연구에서는 공간정보를 바탕으로 한 낙동강 유역에서의 비점오염원 정량화 분석을 수행하고자 한다. 우선 대상유역으로 낙본 G유역을 선정하여 이에 대한 조사를 통해 점오염원의 실측자료를 구축하고 이를 HSPF의 입력하여 모의를 수행하여 대상유역에 대한 실측치를 이용해 모형의 보정과 검증을 수행한다. 이러한 과정을 통해 도출된 결과는 대상유역의 총 오염량을 의미한다. 따라서 위의 과정에서 도출된 매개변수를 이용하고, 점오염원을 제거한 뒤 모의를 재수행하여 나온 결과가 대상유역의 비점오염원의 양이라 판단하였다. 모의 결과 대상유역인 낙본 G유역에서 약 39% 정도의 비점오염원 비율을 보였다. 그러나 수질 및 유량 관측치를 지금까지는 국립환경과학원 낙동강물환경연구소 유량측정데이타를 사용하고 있는데 이 자료는 8일 이상 간헐적으로 측정이 수행되고 있다. 따라서 검 보정 대상이 되는 실측치의 자료의 부족과 부정확한 유역이 있음이 한계점으로 작용한다. 그러므로 추후의 신경망 모형이나 기타 실측치 보간에 있어서의 신뢰도를 높이는 기법 개발이나 측정제도의 보편적인 기술의 증대도 앞으로의 모델링에 있어서 중요할 것으로 판단된다. 또한 유역수질모형의 모델링 과정에서 좀 더 신뢰도 높은 측정자료와 그 측정자료를 활용하여 PEST 보정기법을 적용한다면 더욱 정확한 예측이 이루어질 수 있을 것이며, 본 연구에서의 평가방법을 바탕으로 유역수질모델링이 이루어진다면 보다 더 정확성 높은 비점오염원 정량화와 수질 예측이 수행될 수 있을 것이며 더 나아가 오염총량제의 수행에 효과적으로 적용될 것으로 판단된다.

The aim of this paper is to clarify the Aristotle's conception of change(kinesis). Aristotle defines the change as a process which actualize a potentiality. From Aristotle's definition of the change, a number of consequences flow directly about how to conceptualize it. First, the change is fundamentally directional. Second, if we do not know what the change is directed toward, we do not understand what the change is. Third, everything that changes is caused to change by a distinct cause of change, a changer. Fourth, there is a single actualization of cause and subject of the change. All change, for Aristotle, is the change of an enduring subject. And all change occur in the infinite(to apeiron) which is time, space, matter. It would be absurd to equate the whole and the infinite, for that would be to say that the unlimited had a limit. The infinite does not contain, but in so far as it is infinite, is contained. And due at least in part to its potentiality, the infinite is unknowable. Because it lacks a form. The infinite traditionally derived its dignity from being thought of as a whole in which everything is contained. But Aristotle removes the infinite from its position of majesty. Aristotle's this idea was a revolution in philosophical perspective.

In this paper I undertake to define what is mind, as a partial project of the philosophical foundation of the Mind Humanities. To this end I ask myself, where can be found the field, to which the various or whole psychological concepts and discourses generally relate, and then I identify the correct field to be the field of existential activities of human beings as being-in-the-world. When human beings as being-in-the-world live their lives, her life is built up out of the internal biological activities, the worlds of space and time, and actions. While the various scenes of individual life of man produced by a dynamic coordination of those worldly components, the basis of the mechanism of that coordination is explained by a biological model of self-sufficiency system that I developed here. On the basis of this model, I show step by step, how and through which (logical) way organisms configures their living, as it is. With respect to those steps of the life-construction of the organism, or in light of each step corresponding to each configuration, I construct different types of mind, i.e. impulsive mind, manipulative mind, meta-mind, collective consciousness/mind and finally personality, while every mind is further subdivided. Finally, I define mind, in light of its function in human life and with respect to the generalized sense of the whole processes as outlined above, as an organ which weaves (above mentioned) worldly components to Dasein, and sublimates and expands it to a better living.

도시화는 불투수면의 증가를 야기 시켜 물순환 왜곡, 다양한 오염 물질의 유입으로 인한 비점오염물질 유출, 인공 배출열의 증가로 인한 도시열섬효과 등 다양한 문제를 유발한다. 이러한 수리수문학적 및 환경생태학적 문제를 저감하기 위하여 도시지역과 같은 개발 사업에서는 수환경을 가능한 자연 상태로 복원하는 저영향개발(Low Impact Development, LID)기법이 중요한 대안으로 제시되고 있다. LID기법 중 하나인 옥상녹화는 에너지 이용을 최소한으로 한 자연 녹음의 효과적인 이용을 도모하여 환경공생도시 조성과 식물을 매개로한 자연 순환 과정을 도시구조에 도입하여 순환 시스템 재생이 가능 하도록한다. 노지녹화는 두꺼운 자연 토양을 이용하는 반면 옥상녹화는 적재하중의 제약(옥상의 적재하중 조건은 $150{\sim}180kgf/m^2$이다. 비중이 1.6~1.8인 토양을 20cm 객토한 경우, 약 $320kgf/m^2 $이상의 적재하중이 되기에 식재기반의 경량화는 중요한 사안이다.)으로 인해 용적밀도가 작은 인공경량토양 또는 개량토양을 이용하며, 토양 두께도 얇게 설정된다. 또한 토양의 두께는 식물의 크기와 종류 및 토양의 조성에 따라 다르기에 적재하중 조건을 고려한 적절한 토양과 식재 식물의 크기와 종류 결정은 중요하다. 이에 본 연구에서는 옥상녹화식생에 대한 평가와 이에 대한 시험 프로세스가 가능한 실험 장치를 개발하였다. 옥상녹화 효율성 검증실험장비는 1m*1m*0.6m 아크릴 재질의 녹화셀로 경사조절이 가능하도록 설계하여 경사변화에 따른 유출, 침투, 증발산량의 탄성도 모의 평가를 할 수 있다. 또한 4점식 형태의 로드셀을 이용하여 녹화셀에서 발생하는 증발산량을 측정하고 관측된 증발산량은 RS-232c 이상의 통신프로토콜을 사용하여 주기적인 관측치의 송수신이 가능하며 주기적 자료송수신 외에도 옥상 녹화셀의 측면에 하중 표시기를 설치하여 관측이 가능하다. 또한 저면에 바퀴설치를 통하여 이동 실험이 용이하며 현재 부산대학교 양산캠퍼스 한국 GI&LID 실증단지 연구센터 내 옥상녹화 실험장에 옥상녹화 효율성 검증 실험 장비를 설치하여 자연 혹은 인공강우를 통한 유출, 침투, 증발산량의 시험계측을 실시중이다. 이러한 옥상녹화 효율성 검증실험장비는 최대 하중 2,000kg, 측정해상도 0.02kg 이상을 허용하는 로드셀과 녹화셀을 이용하여 하중을 고려한 식생의 종류에 따른 평가가 가능하므로 최적 식재기반 단면구조 개발에 이용될 수 있을 것이다. 또한 토양 함수량 변화 측정으로 옥상녹화에 이용되는 다양한 종류의 식물의 염분에 대한 저항성과 식물의 성장능력을 평가하여 녹화공간에 따른 옥상녹화에 사용할 식생을 결정할 수 있다.

Until now, most of the attention related information and knowledge transmission is on the verbal message provided by educators. But recently, many researchers are emphasizing importance of nonverbal communication behavior in the evaluation of communicator include educators. When nonverbal messages reinforce verbal messages, meaning is conveyed quickly and easily and with increased comprehension. The purpose of this study is to analyze the effect of professor nonverbal communication on students' academic achievement. In this study, nonverbal communication was divided into the three dimensions of kinesis, proxemics, paralanguage, and physical appearance. It was studied to examine the direct or indirect effects of nonverbal communication on attitude toward the professor and academic achievement. Additionally, it examined the moderating effect of academic self-efficacy in the relationship between attitude toward the professor and academic achievement. The data were collected from 214 college students using an online survey. The results showed that the kinesis, proxemics, and physical appearance, except paralanguage, have significantly positive influence on attitude toward the professor. And the moderating effect of academic self-efficacy has also been founded.

It is important to evaluate the fracture network in a rock volume because fractures control the ground conditions and fluid flow characteristics. Therefore, various attempts have been made to quantify fracture networks to better understand ground and flow conditions. The use of fracture density alone (a quantitative parameter based on geometric analysis) does not fully explain the evolution of fracture networks, or quantify the spatial relationship (e.g. connectivity) of fractures in a rock mass. Therefore, the need for fracture network characterization based on topological analysis has recently emerged. In Korea however, the topological analysis of fracture networks within a rock mass has rarely been studied. As such, the definition of the topological analysis of fracture networks and the graph theory related to the topological analysis are briefly summarized in this study. We also introduce an application method for these analyses to fracture characterization. If the topological method is used for the analysis of fracture networks, it can also be adopted to analyze fluid flow characteristics of groundwater, characterize petroleum reservoirs, and analyze the evolution of a fracture network. In addition, topological analysis can be useful for site selection of major facilities such as nuclear waste disposal sites because it can be used to evaluate the stability of the potential sites.

This paper is to verify the effectiveness of 'Hybrid Disaster Management Strategy' that integrates 'RTM(Real-time Monitoring) based On-line' and 'UAV based Off-line' system. For landslide prone area where sensors were installed, the conventional way of risk management so far has entirely relied on RTM data collected from the field through the instrumentation devices. But it's not enough due to the limitation of'Pin-point sensor'which tend to provide with only the localized information where sensors have stayed fixed. It lacks, therefore, the whole picture to be grasped. In this paper, utilizing 'Digital Photogrammetry Software Pix4D', the possibility of inference for the deformation of ungauged area has been reviewed. For this purpose, actual measurement data from RTM were compared with the estimated value from 3D point cloud outcome by UAV, and the consequent results has shown very accurate in terms of RMSE.

The questionnaire survey for Apis cerana beekeepers and professionals on improved native bee hives was carried out and we compared the temperature, relative humidity(RH), and weight changes of 4 improved hives(Chungju, Miryang, Hanam, and Suwon) from May 1, 2019 to January 31, 2020. Beekeepers need vertical feeder, hive stand, entrance block, and separating panel as hive accessory devices. The average temperatures within brood area were kept constantly (31.3~35.1℃) and the low daily variances of temperature (≤1℃) in Chungju hive among tested hives were observed. The daily temperature variances in the separated space and on the top of winter cluster were not different among 4 hives. In correlation between the temperature of brood area and the number of combs, Chungju hive showed the highest correlation(80.4%) and between the temperature on top of winter clusters and outside temperature, 4 hives showed high positive correlation(76.8~87.1%). RH of brood area(45~60%) in all hives were kept relatively low and constant compared to the outside RH(60~85%). The stablest RH on the top of winter cluster was observed in Suwon hives (65~75%) The highest cumulative weight increase among hives and the high positive correlation(65~67%) between the change of cumulative hive weight and combs number of hives were shown in the Miryang and Chungju. Based on these results, A. cerana bees are able to manage constant temperature and RH within hives area for their colony life, which also effected by the types of hive.
