The purpose of this study is to analyze the visions of visual landscape planning and to suggest improvements for it. This study overviews currents methods of making the vision of visual landscape planning by group interview with hands-on workers. Thirty-two cases of visual landscape planning are reviewed to analyze the forms and contents of vision of visual landscape planning. The purpose of urban vision and city slogans are fairly similar to the vision of visual landscape planning; therefore, this study reviews and compares them. According to this study, we conducted writing direction and policy implications. The results of this study are as follows. The vision of visual landscape planning is written by consulting the landscape resources survey and visions of upper plans. These writing methods are able to enhance the consistency of each chapter in visual landscape planning, and the consistency between visual landscape planning and upper plans. Thus, it is desirable to revise landscape planning guidelines with this method. The current vision of visual landscape planning is written in the form of a city slogan. But the vision of visual landscape planning is not a means of publicity and transformational use. So, the form of the vision needs to be revised. This study analyzed the correlation among the vision of visual landscape planning, urban vision, and city slogan. There is a closer correspondence between the vision of visual landscape planning and urban vision than city slogan. This result means that it is beneficial to write the vision of visual landscape planning in consideration of the upper plan. Henceforward, for maintaining and enhancing consistency detailed contents in landscape planning guidelines are needed.

현재 국내 논벼 수요량 산정방법은 수정 Penman방식에 의한 증발산량을 계산하여 구하고 있다. 증발산량 산정은 여러 가지 방식에 의해 산정될 수 있으나, 유엔의 식량농업기구 (FAO, Food and Agriculture Organization of the United Nations)에서는 작물 수요량 산정에 수정 Penman 공식을 사용할 경우 증발산량이 과다산정 되는 점을 지적하여, 건조 및 습윤 기후에서 비교적 정확하고 일정한 경향을 나타내는 Penman-Monteith(P-M)공식을 사용하도록 추천하였다. 이에 따라 국내 기상청 및 농촌진흥청에서도 증발산량 산정에 P-M공식을 적용하기 시작했으며, 이와 더불어 농촌진흥청에서는 P-M 추정법에 따른 벼를 포함한 주요 작물의 생육단계별 작물계수(Kc)를 제안하였다. 따라서 본 연구에서는 논용수 공급지구 8곳을 선정하여 대상지구별로 기존의 수정 Penman 방식과 P-M 방식을 적용한 경우의 증발산량 차이와 이에 따른 논벼 수요량 변화를 분석해 보았다. 그 결과, 수정 Penman 공식을 적용한 경우에 비해 P-M공식을 적용한 경우 증발산량이 모두 감소하는 경향을 나타내었다. 증발산량 산정방법 변화에 따른 대상지구별로 증발산량 결과값의 변화는 모두 비슷하게 나타났다. P-M방식을 적용했을 경우 잠재증발산량은 11.1%~14.9%(평균 12%)로 감소하였으며, 작물계수를 적용한 실제증발산량의 경우에도 3.8~5.1%(평균 4.6%) 감소하는 경향을 보였다. 이에 따른 논벼 수요량의 변화도 실제증발산량의 변화와 비슷한 감소 경향을 보였다. 다음으로 P-M방식을 채택한 경우의 논벼 수요량의 생육시기별 변화를 조사해 본 결과, 이앙기 수요량은 2.1%~6.3% (평균 4.4%)로 증가하다가, 본답기에는 수요량이 5.1%~11.3%(평균 8.4%)로 감소하였다. 전반적인 증발산량은 본답기 수요량 감소분이 이앙기 수요량 증가분보다 더 크기 때문에 감소경향을 나타낸 것으로 파악되었다. 또한 이앙기 수요량과 본답기 수요량의 증감의 경향이 다르게 나타난 것은 증발산량 산정방식의 변화에 따른 생육시기별 작물계수의 차이로 인한 변화로 파악되었다. 논벼 수요량은 농업용수 공급계획 수립의 주요기준이 되는 인자이므로, P-M방식 적용에 따른 논벼 수요량의 산정결과에 대해 보다 면밀한 검토가 필요할 것으로 사료된다.

Change of Zoning Regulations in district unit plans calls for improving development benefits through upzoning rather than harmonious worldwide development. The purpose of this study is to examine the floor area ratio incentive system according to un-zoning in district units plan, and to suggest criteria to secure publicness. In order to derive methods to secure district unit plan publicness in Busan Metropolitan City, the ratio of securing public facilities through upzoning was examined. A comparative analysis of land price rate in the entire city versus the use district suggests that it is possible to secure 10 to 15% of public facilities. In this study, 10% of the project site was applied to secure public facilities, and it produced upgraded publicness.

최근(2014~2017년) 강수량은 평년대비 71% 수준으로 2017년에는 누적된 강우부족으로 극심한 가뭄피해가 발생하였다. 용인시 또한 최근의 3년(2014~2017년)의 경우 연속으로 100년 빈도에 해당하는 가뭄이 발생하는 등 심각한 가뭄이 발생 되었으며, 하절기를 제외한 기간의 경우 평년에 가까운 강수가 발생하나, 하절기에는 강수가 매우 작아 심각한 가뭄이 발생하는 경향으로 조사되었다. 용인시가 관리하는 소규모 농경지는 대형농업용 수원공이 없어 작은 가뭄에도 쉽게 피해가 발생되고, 저수지, 취입보, 양수장 등 수원공이 설치되어 있으나 내한능력 부족 및 영농방식 변화 등으로 상습적으로 가뭄 피해를 입고 있다. 또한, 관리 농경지 및 농업 수리시설물에 대한 현황조사 미비로 상세한 이력 관리가 되어 있지 않아 시설물의 유지관리 및 중장기 계획 수립이 어려운 실정으로 수리시설물에 대한 이력조사가 요구되며, 전체 용수 수요량의 60% 이상에 해당하는 농업용수의 체계적인 조사를 실시하여 항구적 가뭄극복을 하기 위한 가뭄분석을 하였다. 본 연구에서는 농경지에 대하여 관개계획 기준치를 보통 10년 빈도의 가뭄에 극복이 가능하도록 설정하므로, 계획빈도의 가뭄에 안정적으로 농경지에 농업용수가 공급될 수 있도록 기설 수리시설물의 공급능력을 검토하여 확인하였다. 용인시 전역에 대하여 우선 기초자료로 기상 및 수문조사와 농촌용수관련인자를 조사하였으며, 상위 관련계획 조사로 농업·가뭄·수자원 관련계획을 조사하였다. 기존 저수지 농업용수 공급능력은 유역의 유입량은 DIROM모형을 사용하여 산정하고 관개구역의 필요수량은 Penman방법으로 증발산량을 산정하였다. DIROM 모형과 Penman방법으로 산정된 자료를 참고하여 기존 수원공 시설의 물수지 분석을하여 과정에 HOMWRS(수리시설모의조작시스템) 모형을 적용하여 농경지 필요용수량과 공급 가능량, 지하수 취수량의 능력검토를 하였으며, 가뭄 계획빈도 10년 조건에서 농업용수 공급능력을 검토한 결과 수리적으로 안전한 농경지는 전체 농경지 대비 64.18%로 확인되며, 향후 강우 전망 RCP6.0 시나리오에서 2021년~2040년에 5.1%정도 감소하는 것으로 전망된 것을 감안하면 향후 용인시 지역은 가뭄이 보다 심화될 것으로 판단되므로 시급히 구조적 대책이 가능한 여건의 지역에 한하여 수원공 시설을 확보하여 가뭄에 반드시 대비하여야 할 것으로 판단된다.

When we face an unexpected challenge, should we stick to the original plan and persevere through the series of challenges? Or shall we pivot and transform our original plan into something new by taking into account the newly acquired information? This perennial question of perseverance versus pivot as two competing problem-solving strategies has puzzled our every day lives. In this study, based on the large-scale, nation-wide survey on entrepreneurship, I found that individual entrepreneurial orientation, which consists of innovativeness, risk-taking, and proactiveness, promotes an individual's tendency to choose new problems to solve. Perseverance strategy was found to positively moderates the relationship between innovativeness and the tendency to choose new problems to solve, whereas the relationship between risk-taking and the tendency to choose new problems to solve was found to be negatively moderated by perseverance strategy. Pivot strategy, on the other hand, was found to be positively moderates the relationship between proactiveness and the tendency to choose new problems to solve. These findings contributes to the stream of individual entrepreneurial orientation research by empirically testing two competing problem-solving strategies of perseverance and pivot to show their interaction effects with entrepreneurial orientation. Also the findings of this study expand the potential outcome of entrepreneurial orientation by adding an individual's tendency to choose new problems to solve rather than what he or she has already experienced before.

The purpose of this study is to quantitatively and effectively evaluate the factors affecting flood damage by watershed. National Water Resource Plan(MOCT, 2001) has been developed Potential Flood Damage(PFD) which indicates flood vulnerability. But, it is only a simple grouping and it does not provide guidelines for flood control planning based on detailed evaluation of sub-components. In this study, we used PFD in the Han River basin according to the method applied in the National Water Resource Plan (existing method) and improvement based on actual flood hazard area and data. As an application method, after analyzing by yearly change(2009~2014), we compared and analyzed the tendency of the sub - components that constitute the potential and risk rather than the current grouping. As the result, it was possible to accurately evaluate the existing and improved methods, and it was possible to derive the vulnerability rankings, but the existing methods have different results from the actual watershed tendency. Therefore, the PFD of the improvement method that correctly reflects past history and watershed characteristics is more appropriate for the evaluation of flood vulnerability in the watershed. In addition, it is reasonable to establish a flood control plan referring to this and prevent flood damage in advance.

Images of Seong-Nam appears different according to diverse conditions. This study was intended to analyze the differences of cognition by personal characteristics such as age, gender, location, and period when an individual evaluates an urban image. This research focused on the interpretation of the visualized results from Multidimensional Scaling (MDS) and Individual Difference Scaling (INDSCAL) with two questionnaires. This study can be summarized as follows: 1. Namhan Sansung was ranked as the first symbolic property by citizens in Seong-Nam. Next was Yuldong Park, followed by Bundang Central Park, Seohyun Station including Samsung Plaza, and, finally, Moran Market. This trend also similarly appeared in the selection of preferred places. 2. There were no statistical differences in trends of choice of symbolic landmarks and preferred places according to age, gender, and period; however, there were meaningful differences according to location. 3. The total image of Seong-Nam was positioned to be separated from images of other districts and landmarks on the image spatial plot by MDS; however, images of the old and new district were plotted close to symbolic landmarks where located around each district. 4. INDSCAL illustrated that men weighted the historical meaning while women weighted preference and city size when evaluating an urban image. On the other hand, there was no difference in cognitive trends according to age, location, and period. Until now, an individual difference in the cognition and evaluation of an urban image was a socially accepted notion. However, this study verified the difference according to personal characteristics and developed a practical tool to analyze an individual cognition trend about a city image.

The river master plan was established every 10 years in Korea. The basin characteristics of 62 small and medium size rivers of which master plans were recently established during the past three years in Gyeonggi-do were investigated, and design rainfalls and design floods in the past and the latest were compared and analyzed. It was predicted that basin data and flood estimating method changed design flood. The quantitative amount of design floods were analyzed for 6 basins like Gungunchen etc. As the results, the increasing factors of design flood were the application of critical duration time, temporal time of rainfall and the increase of CN value. The decreasing factors of design flood were the application of Huff's rainfall distribution instead of Mononobe one and the ARF. The application of critical duration time increased flood about 60% whereas the application of Huff's rainfall distribution method estimated less flood than Mononobe about 62%. Considering critical duration time and changing rainfall distribution were the most important factors of increasing or decreasing design flood. However, trends of flood variation were differently analyzed by factors in 6 basins because characteristics of topography, weather, hydrology and hydraulic were different, now that correlations were not found between factors and flood variation. Flood variation is evaluated by complex effects of factors so new flood recalculated by reasonable methods should be considered as design flood.

The development and reduction scheme under implementation plan of TMDLs were performed in the Jinwi watershed including 8 cities (Gunpo, Yongin, Suwon, Anseong, Osan, Uiwang, Pyeongtaek and Hwaseong) since 2012. Progress of the annual development schemes was faster than the reduction schemes in most of the cities during the planning period. Main load reduction methods included establishment and enlargement of sewage treatment plants, resources of livestock excretions, and introduction of best management practices of non-point source pollution. Especially, reduction load using recycling and composting of livestock excretions comprised 34.1% of all reduction load. It is necessary to implement methodical development and reduction scheme for making of successful performance of TMDLs and water quality improvement in the Jinwi watershed.
