Global companies regard the conditions of a location as one of the most crucial factors to assess the competitiveness of ports and the port hinterland, as well as emphasize creation of throughput and the importance of value added logistics in the hinterland under diffusing Supply Chain Management(SCM). This study deals with the evaluation of competitiveness in 7 hinterlands and the establishment of assessment model in hinterland. This study analyzes the importance of factors for the port hinterland competitiveness using AHP method. As a result, logistics factor, accounting for 62.3%, is shown as the relative more important factor, followed by hinterland's economy factors(27.3%) and city/policy factor(10.4%). The result implicates that measures to activate logistics factors with relatively high importance are essentially needed in order to improve the competitiveness of the hinterland of Busan New Port. Especially, it is needed to establish service routes of the port and air networks and to expand infrastructure for support. This study also assesses the competitiveness of hinterlands for the seven domestic and foreign ports based on importance of assessment factors for the hinterland competitiveness using AHP analysis. Busan(3.903) is ranked fourth behind Singapore(4.570), Hong Kong(4.357) and Shanghai(4.042) in assessment.

The purpose of this study was to analyze the monumental expression of Korean War Memorials(KWM) in Korea(KWMK). Through site survey and internet searching, the researcher selected 17 KWMK and analyzed four analysis categories: contents, spatial form, landscape elements, sculptures and architectural elements. The results are as follows: 1. The analysis revealed that main contents of KWMK were to cherish victims of the Korean War, honor military merit, and explain Korean War. 2. Most KWMK built battlefield had the form of symmetry and spatial axis arranged monuments and sculptures for solemnity and heroism. Though the sites were terraced by traditional spatial order, spatial sequence wasn't seen except Yang-gu KWMK and Chumomyeongbi in United Nations Memorial Cemetery in Korea. 3. Stone monument-like towers, tablets, podium, monoliths, cenotaphs, and exhibit halls to explain Korean War and combat history were used as main elements of KWMK and also, war weapons were often displayed the flags of countries taking part in Korean War were raised with Taegeukgi and the United Nations flag. 4. Most sculptures were used as important media to represent the Korean War and assumed realistically the form of heroic combat. But a few architectural memorial built in recent were designed in contemporary style to have spatial sequence and represent Korean War symbolically and narratively. 5. In memorial culture, KWMK were strongly influenced by ideology and patriotism, impacted by conventional value, and designed by some sculptors and designers in a certain circle. Further study will be required to analyze the characteristics of KWMK in the point of design style and diachronic.

Using the dynamic panel model, this study investigates rent determinants for small and medium-sized office buildings in Korea's CBD and Gangnam areas, key business districts. The results reveal that rents for small and medium-sized office buildings in CBD and Gangnam areas are influenced by macroeconomic fluctuations and characteristics of buildings and locations, suggesting a market with both spatial consumer and investment goods attributes. There are several investment implications as follows. First, even if the location in the CBD area is advantageous, the practical limitations in renovating aging small and medium-sized office buildings must be taken into account when investing. Second, parking conditions are a key factor influencing rent prices in CBD areas, so evaluating the parking facilities and improvement potential of small and medium-sized office buildings is essential for investors. Finally, due to the high sensitivity of Gangnam's small and medium-sized office market to macroeconomic trends, it's vital to prioritize monetary policy shifts as a key factor in investment decisions.

The government has been operating residential improvement projects through the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents" as a type of a remedial measure for deteriorated residential areas. However, in recent years, the residential improvement projects have experienced difficulties due to the effects of various factors including the slowdown in economic growth. After observing the depression in a number of projects, various studies have been carried out to investigate the causality and improve the promotion of the residential improvement projects. In the trend of research, this study aims to analyze the effects of land and building characteristics on the improvement projects of Busan Metropolitan City. The dependent variables of the study represent different phases of improvement project as specified in the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents". The independent variables represent land and building characteristics which refer to the criteria used in the designation process of maintenance area according to the act. The empirical analysis uses the ordered logit model. The results from the analysis suggest that geographical condition, factors related to the number of union members, factors related to the parcel price and condition of a location have impact on the promotion of the improvement project. The results of the analysis show that majority of the factors are related to the economic feasibility of the projects. Residential improvement project is a part of urban planning projects that rehabilitates deteriorated residential environment, and it is closely associated with the quality of life of public. Accordingly, we hope that such projects are reasonable and take effective approach to those with urgent needs rather than to focus on profitability. Also, potential administrative and economical loss should be avoided by taking necessary planning measures in advance.

The purpose of this study is to analyze the efficiency of PV according to installation condition in the complex type buildings. For this purpose, annual performance of solar power generation in a certain area was investigated and various methods were conducted including post operation evaluation. In addition, we tried to find out influencing factors that affect the efficiency and sought to identify their relative impact of degree through the data analysis and site visits together. In the middle of this process we can draw up major considerations for the efficient photovoltaic power generation installation. In the mean while, previous studies are making something new related with method for efficiency enhancement and individual influential factors based on experimental environment rather than the empirical data site based. As a result of the study, it was confirmed that even if installed in the same area, the power generation efficiency is 1.5 times as high as the installation condition. Furthermore, statistical analyses were performed on azimuth, tilted angle and shade, which are variables affecting conversion efficiency, and it was statistically confirmed that all variables are meaningful factors that affect the conversion efficiency which is a dependent variable. The most influential factor is the azimuth, followed by the tilted angle and the shade factor. From this result, we expect to be able to provide installation guidelines for the solar power generation equipments on the rooftop zone.

The purpose of this study to analyze the regional competitiveness of the part material industry in Korea. According to the analysis, there was an empirical regional difference in the part material industry in Korea: in the Seoul Metropolitan Area, the industrial scale was found to be relatively small, although many companies were observed to be in the growing stage; in the Chungcheong region, it was estimated that the industrial scale is large, and many companies were found to have already reached the maturation stage with high growth rates; and in Honam and Jeju, Daekyung and Gangwon, and Dongnam, although the scale of the part material industry was found to be large, many companies were observed to be in the declining stage with low growth rates. This study also conducted an analysis based on LQ (Location Quotient) and RLQ (Relative efficiency of Labor Quotient). The analysis showed that industrial policies regarding workforce planning and industrial restructuring should focus on improving the productivity of the entire part material industry. Lastly, this study examined the competitive part material industry for the five regions by analyzing the RCC (Regional Competition Component). The findings of this study will be helpful in exploring ways to support the domestic part material industries in each region.

When the offshore wind power plant is planned to construct, it is important for the wind farm site to figure out the distribution of the weak soil layers that might cause subsidence by the impact of the external moment from the wind plant's load and an oscillating wind load. Coring test is the optimistic method to figure out weak soil layers, but this method have some problem such as condition of the in-situ or economical limitation. In order to make up for the weak points in coring test, the researches using the geostatistics methods is actually done. In this study, setting a fixed coastal area that offshore wind plants construct firstly and Estimation of distribution on the thickness of the weak soil layer through the geostatistic method is conducted. The weak soil layer is sorted by result of the Standard penetration test, geostatistic method is used to ordinary kring and sequential gaussian simulation and compared to both method's result. As a results of study, we found that both methods show similar estimations of deep weak soil layer and we could evaluate quantitatively the uncertainty of the result.

전 세계는 현재 이상기후와 국지적인 돌발호우 및 가뭄으로 많은 어려움을 겪고 있다. 우리나라도 예외가 아니어서 지난 겨울에 많은 폭설로 여러 지역에서 도로단절, 농작물 피해 및 공공 시설물의 파괴 등 날로 기후변화에 따른 피해가 증가하고 있다. 또한 지난 몇 해 전에도 강원도지역 가뭄으로 인한 식수 및 농업용수 부족으로 인근 지역의 식수원 및 농작물 피해를 겪어야만 했다. 이러한 수자원의 변화에 능동적으로 대처할 수 있는 방법은 여러 가지가 있겠으나, 대규모 저수지 및 랩을 신설하는 것이 가장 수자원확보에 용이한 방법이다 그러나, 대규모 저수지 및 댐을 건설할 수 있는 적지의 감소로 수자원확보가 예전보다 수월하지 않다. 이러한 대안으로 기존 수자원시설물의 개량 혹은 재개발로 수자원의 일부인 농업용수를 확보하는 경제적인 방안이 활용되고 있다. 농업용 저수지중 콘크리트 댐으로 구성된 제체 높이를 17.0m에서 3.1m 높여 20.1m로 증고하여, 환경용수를 포함한 유효저수량을 184만 $m^3$을 추가 확보하여 하류 수혜구역 485.9ha에 농업용수 공급 및 갈수기 하류하천의 환경용수를 제공할 수 있도록 계획하였다. 경상북도 남동단에 형산강 지류에 위치한 OO 저수지는 기계천을 중심으로 형산강에 도달하며 동쪽으로는 포항시 신광변, 북쪽으로는 포항시 죽장면과 경계를 이루고 있다. OO 저수지는 기존 저수지 콘크리트 범 상류면 보강 및 내측 덧쌓기, 하류면 보강 및 외측 덧 쌓기, 기존 저수지 하류에 신설탬을 설치하는 안으로 비교하여 결정하였으며, 저수지 제체 입지 여건 등을 종합적으로 비교 검토한 결과 콘크리트 댐 상류면에 보강 및 내측 덧쌓기 안이 가장 시공성에 있어 효율적이며 경제적이므로 선정하여 계획하였다.
