This study is aimed at identifying the value of marginal products(VMP) of agricultural labor, capital and land. The resources are the major portion of input costs of agricultural projects. To appraise economic feasibility of agricultural projects, the real value of the resources would be estimated by VMP of the inputs rather than by distorted actual market prices such as rural wages, rent and interest. To convert the market wage rate into shadow wage rate, covertion factor of 0.90 would be appicable based on the study results. To evaluate the right of way and compensation, VMP of land is recommendable to apply in land pricing rather than actural land rent prevailing in rural area which has been underrated on account of labor shortage and difficulty of farming. Discount rate as a opportunity cost of capital should be applied 7-8% considering the VMP of capital and interest rate of foreign loan from IBRD and ADB. For the successful appraisal of the agricultural projects, the recommendation of this study would be applied in the future.

우리나라 부동산의 예측할 수 없는 매매가로 인해 경제가 혼란스러운 최근에 토지정책의 패러다임 전환론과 더불어 토지평가자료의 객관적 적정성에 대한 문제가 심각하게 논의되고 있다. 특히 공시지가자료가 공신력을 인정받지 못함으로서, 토지보상금이나 개발부담금을 산출하는데 필요한 지가가 별도의 방법으로 산정 되는 등 공적지가 산정의 일원화를 목적으로 도입된 공시지가제도가 기본기능을 수행하지 못한다는 비판이 제기되고 있다. 공시지가의 적정성을 위해 가장 중요한 사항은 토지평가 항목이 합리적으로 선정되어야 한다. 또한 인터넷을 통한 정보의 홍수시대에 살고 있는 현대인들에게 신뢰할 수 있는 토지평가자료를 제공해주는 디지털컨텐츠의 개발이 시급한 상황에 있다. 본 연구에서는 통계적 기법을 이용하여 실거래지가와 형평성을 유지하도록 하는 토지평가모형 개발의 방법론을 제안하고 실거래지가에 기초한 토지평가 디지털컨텐츠를 개발하기 위하여 용도지역별로 실거래지가에 영향을 미치는 항목을 기존의 부동산 웹사이트의 자료를 이용하여 분석한다.

SAR (Synthetic Aperture Radar) is an effective tool for monitoring areas damaged by disasters. Full PolSAR (Polarimetric SAR) enhances SAR's capabilities by providing specific scattering mechanisms. Thus, full PolSAR data have been widely used to analyze the situation when disasters occur. To interpret full PolSAR data, model-based decomposition methods are frequently used due to its easy physical interpretation of PolSAR data and computational efficiency. However, these methods present problems. One of the key problems is the overestimation of the volume scattering component. To minimize the volume scattering component, the OA (Orientation Angle) compensation method is widely utilized. This paper shows that the effect of the OA compensation was analyzed over landslide affected areas. In this paper, the OA compensation is applied by using the OA estimated from the maximum relative Hellinger distance. We conducted an experiment using two full polarimetric ALOS/PALSAR (Advanced Land Observing Satellite/Phased Array type L-band Synthetic Aperture Radar)-2 data collected over Mocoa, Colombia which was seriously damaged by the 2017 Mocoa landslide. After OA compensation, the experimental results showed volume scattering power decreased, while the double-bounce and surface scattering power increased. Particularly, significant changes were noted in urban areas. In addition, after OA compensation, the separability of the double-bounce and surface scattering components are improved over the damaged building areas. Furthermore, changes in the OA can discriminate visually between the damaged building areas and undamaged areas. In conclusion, we demonstrated that the effect of OA compensation improved the influence of the double-bounce and surface scattering components, and OA changes can be useful for detecting damaged building areas.

According to the 2012 social blue book released by the Chinese Academy of Social Sciences, China's urban population reached 50% in 2011. With the migration from marriage and new household registration, many urban collective assets have been formed in cities. Due to the unclear property rights and the emptiness of the main body, the distribution of collective assets mostly depends on the village cadres. The central government is preparing relevant laws and regulations to fill this legal gap, while the scheme of restructuring is decided by the villagers' vote, the local government coordinate the land acquisition and management. With the process of urbanization, a large number of second-generation of demolition studied abroad, which has attracted worldwide attention. In addition to the huge amount of compensation, due to the continuous rising of the land price, the value of the collective property and enterprises on the land also keep rising, the management agency of these assets is named village economic cooperative. This paper seeks to analyze the current status and future direction of these wealthy organizations, propose solutions to some existing problems.

Underwater archaeology relies heavily on photography and video image recording during surveillances and excavations like ordinary archaeological studies on land. All underwater images suffer poor image quality and distortions due to poor visibility, low contrast and blur, caused by differences in refractive indices of water and air, properties of selected lenses and shapes of viewports. In the Yellow Sea (between mainland China and the Korean peninsula), the visibility underwater is far less than 1 m, typically in the range of 30 cm to 50 cm, on even a clear day, due to very high turbidity. For photographing 1 m x 1 m grids underwater, a very wide view angle (180°) fisheye lens with an 8 mm focal length is intentionally used despite unwanted severe barrel-shaped image distortion, even with a dome port camera housing. It is very difficult to map wide underwater archaeological excavation sites by combining severely distorted images. Development of practical compensation methods for distorted underwater images acquired through the fisheye lens is strongly desired. In this study, the source of image distortion in underwater photography is investigated. We have identified the source of image distortion as the mismatching, in optical axis and focal points, between dome port housing and fisheye lens. A practical image distortion compensation method, using customized image processing software, was explored and verified using archived underwater excavation images for effectiveness in underwater archaeological applications. To minimize unusable area due to severe distortion after distortion compensation, practical underwater photography guidelines are suggested.

As the land price in the downtown area increases, buildings are becoming bigger, deeper and higher. Consequently, the importance of underground construction has increased. Although construction engineers make every effort to complete underground construction without any problem, construction failures like landslides and the collapse of a retaining wall occur because of the uncertainty of the soil conditions as well as the unexpected risks of excavation work. In order to prevent potential excavation accidents, it is essential to understand the causes and impacts of such accidents. However, there are only a few examples of construction failures, which show the economic impact on accidents during excavation because of the sensibility of the information. This paper presents two cases of excavation accidents, which were investigated by construction insurance company. The compensation for the accidents paid by the insurance company was compared with the estimated costs calculated based on the estimation method for excavation accidents proposed by our previous study. The comparison results showed that the estimate calculated by our method was much less than the actual compensation because the estimate solely focused on the construction costs whereas the compensation included other external factors.

In order to increase system capacity and reduce the transmitting power of the user's equipment, we propose an advanced power control scheme consisting of a modified open-loop power control (OLPC) and closed-loop power control (CLPC) for land mobile satellite communication systems. The improved CLPC scheme, combining delay compensation algorithms and pilot diversity, is mainly applied to the ancillary terrestrial component (ATC). ATC link in urban areas, because it is more suitable to the short round-trip delay (RTD).

본 연구의 목적은 공기업 조직에서 성과주의 인적자원관리가 조직유효성에 미치는 영향을 실증분석을 통해 확인해 보는 것이다. 독립변수로는 '성과중심 채용', '성과중심 평가', '성과중심 보상'으로 하였고, 종속변수는 '직무만족'과 '조직몰입'으로 하였다. 실증분석 결과, 최근 정부와 공공부문에서 적극 도입확산되고 있는 '성과중심(직무능력) 채용'이 '직무만족'과 '조직몰입'에 모두 긍정적인 영향을 주었으나, '성과중심 보상'은 직무만족'과 '조직몰입'에 모두 긍정적 영향을 주지 못했다. 또한 '성과중심 평가'와 '성과중심 보상'은 '조직몰입'에 모두 긍정적인 영향을 주지 못하는 것으로 나타났다. 반면, '성과중심 평가'는 '직무만족'에는 긍정적인 영향을 주었다. 본 연구의 실증분석에서 성과주의 인적자원관리의 조직유효성에 대한 긍정적인 효과는 부분적으로 확인되었다. 이러한 결과는 조사대상 공기업이 처한 특수한 상황에서 기인했을 것으로 판단된다. 해당 공기업은 2009년 통합 이후 성과주의 인적자원관리의 다양한 제도와 시스템 도입을 추진하고 있는 반면, 경영정상화 차원에서 자구노력의 일환으로 임금동결과 반납 등 어려운 시기를 겪어왔기 때문에 이러한 조직적 상황이 정상적인 성과주의 인적자원관리의 효과 검증에 영향을 미쳤을 것으로 판단된다.
