본 연구는 전라북도 남원시의 맞춤형 조림지도인 적지적수도를 제작하기 위해 수행하였다. 이를 위해 남원시에 분포하는 주요 수종별 지위지수 추정식을 개발하고, 수종별로 적지에 적합한 입지조건을 반영한 생육범위를 고려하여 각 수종의 적지분포를 공간적으로 평가하였다. 남원시에 분포하는 주요 8개 수종별 지위지수 추정식은 각각 4-5개의 환경인자 조합이 관여하는 것으로 분석되었으며, 전체 27개의 환경인자 중에서 15개가 수종별 지위지수 추정에 사용되었다. 특히 사면위치($X_7$)와 경사형태($X_8$), B층 건습도($X_{11}$), 연최저 기온($X_{15}$), 온량지수($X_{16}$) 비생장기간 5개월 동안의 총강수량($X_{23}$), 월평균 상대습도($X_{24}$), 그리고 생장기간 초기 3개월 동안의 월평균 상대습도($X_{25}$)가 수종별 지위지수 추정식에 많이 포함되는 것으로 판명되었다. 이상과 같은 방법으로 남원시의 적지적수도를 제작한 후, 적합성 검증을 위해 현지 확인 조사를 수행하였다. 현지 확인 결과 본 연구에서 제작한 적지적수도는 사용 가능한 자료의 한계에도 불구하고 수종별 적지분포를 비교적 무난하게 표현하고 있는 것으로 평가되었다. 하지만 부적지로 평가된 일부 지역의 경우 수정 및 보완이 필요한 것으로 나타났다.

Purpose: By analyzing what kind of organizational reaction is shown by employees to corporate social responsibility (CSR), I want to propose a plan to maximize achievement(organizational commitment and productive behavior) within corporation. Methods: Regression analysis is used to analyze relationship between CSR awareness and achievement within corporation. Then structural equation model is used to check control effect of corporate member's participation in CSR. Results: It is proved that employee's CSR awareness has positive relationship with organizational commitment and productive behavior. It is shown that when employees have participated in CSR programs directly, effectiveness of relationship was especially higher for Organizational Citizenship Behavior (OCB) and innovative behavior. Conclusion: In order to increase organizational commitment and productive behavior of employees, corporation's social responsibility management, in other words ethical management must be used so their motivation can be increased and so they can directly participate in CSR programs which will increase effectiveness of organization.

This Paper examines theoretical terrains and design strategies of landscape urbanism which is an emerging hybrid field at the intersection of architecture, landscape architecture, and urbanism. Landscape urbanism offers alternative approaches for theory, education, and practice in contemporary landscape architecture. It views the emergent urban complex sites-post-industrial sites, landfill, brownfield, urban void, etc., not as a weakness, but as a strength. Landscape urbanism poses an understanding of landscape as an element of urban infrastructure. In this sense, the landscape is seen in the context of contemporary urban development and public works. As a complex amalgam, landscape urbanism is more than a design style it is an ethos, an attitude, a way of thinking and acting. We can chart the main characteristics of landscape urbanism such as horizontality and surface, infrastructure, process, technique, and ecology. Multilayered examples of landscape urbanism can be seen in several experimental practices such as worts of Rem Koolhaas, MVRDV, Adriaan Geuze/West 8, James Comer, etc. It is possible to summarize the productive strategies for landscape urbanism as follows : thickening, folding, new materials, nonprogrammed use, impermanence, and movement.

As buildings becoming higher and more enormous the portion of steel works has been increased, which makes the schedule planning and management more significant. However, in actual construction sites, management is more based on a manager's construction experience than productivity data accumulated in previous projects. Moreover, most of the existing studies also featured a theoretical approach rather than an analysis of data straightforwardly collected in sites. In this study, a steel-erection site was visited to collect productivity data. The study found that there were significant disparities between aboveground work productivity and underground work. However, the productivities of 'first node on ground' and 'second node on ground' were estimated similar. The productivity data collected and factors affecting the productivity will help managers to plan and control their similar steel-erection works. This study will also be beneficial for those performing related studies.

This study was conducted to estimate site productivity of Quercus acutissima and Quercus mongolica by four forest climatic zones. We used site environmental variables (28 geographical and pedological factors) and site index as a site productivity indicator from nation-wide 23,315 stands. Based on multiple regression analysis between site index and major environmental variables, the best-fit multivaliate models were made by each species and forest climatic zone. Most of site index prediction models by species were regressed with seven to eight factors, including altitude, relief, soil depth, and soil moisture etc. For those models, three evaluation statistics such as mean difference, standard deviation of difference, and standard error of difference were applied to the test data set for the validation of the results. According to the evaluation statistics, it was found that the models by climatic zones and species fitted well to the test data set with relatively low bias and variation. Also having above middle of site index range, total area of productive sites for the two Quercus spp. estimated by those models would be about 6% of total forest area. Northern temperate forest zone and central temperate forest zone had more productive area than southern temperate forest zone and warm temperate forest zone. As a result, it was concluded that the regressive prediction with site environmental variables by climatic zones and species had enough estimation capability of forest site productivity.

The aim of this paper is to propose the preservation of buffaloes not only as productive livestock, but also as a part of the biodiversity of wetlands and especially of the Greek wetlands. The water buffalo used to be an integral part of the biodiversity of many Greek wetland ecosystems, enriched their landscape, and provided invaluable services and products to the rural people and to the economy in general. Its total population before the 1950s was over 100,000 animals. Presently, it is found only in four wetland sites in Macedonia and Thrace and in the estuaries of Rivers Gallikos and Axios, with a total population of a few hundred animals. These wetlands are Ramsar Sites. Even this small population is threatened with immediate extinction because of the rapidly changing rural socio-economic conditions and the expansion of cultivated fields into wet meadows. Farmers and consumers are rapidly losing contact with this mammal and its products. This species possesses minimum requirements for treatment and is characterized by the ability of utilizing roughage of variable nutritional value. These factors are promising to render buffalo breeding a valuable branch of the Greek livestock sector, which can also contribute to the maintenance of the wetlands.

In today's construction industry, buildings have been more complicated and higher, the demands of steel works have been increasingly concerned, which makes the schedule planning and management more significant. However, in actual construction sites, management is more based on a manager's construction experience than productivity data accumulated in previous projects. Moreover, most of the existing studies also featured a theoretical approach rather than an analysis of data straightforwardly collected in sites. In this study, a steel-erection site was visited to collect productivity data. The study found that there were significant disparities between aboveground work productivity and underground work; one tower crane operated work and two tower crane operated; and work productivity conducted in clear weather condition, cloud and rainy. However, the productivities of 'first node on ground' and 'second node on ground' were estimated similar. The productivity data collected and factors affecting the productivity will help managers to plan and control their similar steel-erection works. This study will also be beneficial for those performing related studies.

The word \"permaculture\" is a contraction of \"permanent agriculture\" or \"permanent culture\". Permaculture principles are designed to support (or ensure) the survival of humanity, the earth and all on it, and, to improve our standard of living, Permaculture can be defined as : a design system for creating sustainable human environments that can be (relatively) easily constructed and maintained. The principles of permaculture designs are relative location every element (such as house , rice paddy, road, esc) is placed in relation to each other such that each assists the other : each element performs multiple functions ; each function is supported by many elements : energy efficient planning ; using biological resources rather than fossil fuels : energy cycling on site (both fuel and human energy) : Using and accelerating natural plant succession to establish favourable sites and soils ; poly-culture and diversity of beneficial species for a productive, interactive system ; use of edge and natural patterns for best effect. These principles can be used for any permaculture design, in any climate, and at any scale. There has been very little scientific examination of Permaculture, and as such, it must be viewed as a design philosophy.viewed as a design philosophy.

Endobronchial metastases from extrathoracic primary malignancies are uncommon. Breast, renal, and colonic carcinomas are primary sites most likely to give rise to endobronchial metastases. A number of other tumours have been reported as being complicated by endobronchial metastasis, including ovarian, thyroid, uterine, adrenal, testicular and prostatic carcinomas. The incidence of endobronchial metastasis has been estimated at 2% in patients who died of metastatic disease. Lung parenchymal metastases are common manifestations in patients with rectal cancer, however spread to the major airway is extremely rare. We herein report a case of endobronchial metastasis from rectal adenocarcinoma. A 69-year-old male patient who had been previously treated with surgical resection with rectal cancer presented with a 8-month history of gradually increasing dyspnea and non-productive cough. Clinical and radiological investigations revealed endobronchial metastasis involving, and penetrating, the lower carina and the left main bronchus. We confirmed endobronchial metastasis from the rectal carcinoma by bronchoscopic biopsy.
