        In order to reduce seismic responses of a structure, additional dampers and vibration control devices are generally considered. Usually, control performance of additional devices are investigated for optimal design without variation of characteristics of a structure. In this study, multi-objective integrated optimization of structure-smart control device is conducted and possibility of reduction of structural resources of a building structure with smart top-story isolation system has been investigated. To this end, 20-story example building structure was selected and an MR damper and low damping elastomeric bearings were used to compose a smart base isolation system. Artificial earthquakes generated based on design spectrum of low-to-moderate seismicity regions are used for structural analyses. Based on numerical simulation results, it has been shown that a smart top-story isolation system can effectively reduce both structural responses and isolation story drifts of the building structure in low-to-moderate seismicity regions. The integrated optimal design method proposed in this study can provide various optimal designs that presents good control performance by appropriately reducing the amount of structural material and damping device.

        The shortwave aerosol direct radiative forcing (SWARF) was analyzed using the Clouds and Earth’s Radiant Energy System (CERES) data in the East Asian region from 2001 to 2010. In the Yellow Sea and the Korean Peninsula, located in the leeward side of China, significantly negative high SWARF at the top of atmosphere (TOA) occurs due to the long-range transport of anthropogenic (e.g. sulphate) and natural aerosols (e.g. mineral dust) from the East Asian continent. Conversely, eastern China has much higher levels of SWARF at the surface (SFC) due to anthropogenically emitted aerosol than in the Yellow Sea and the Korean Peninsula. Since the radiative forcing of aerosols in the atmosphere are different in type, aerosol types were classified into sea salt+sulphate, smoke, sulphate and dust by using satellite data. The analysis on the SWARF by the classified aerosol types indicated that sulphate occupies a predominant portion of the atmosphere in the Yellow Sea and the Korean Peninsula in the summer. In particular, the annual averages of the summer TOA SWARF increased in the Yellow Sea and the Korean Peninsula from 2001 to 2010.

        This study was conducted to investigate the correlations between the PM10 concentration trend and meteorological elements in the Gimhae region and analyze the transportation routes of air pollutants through back-trajectory analysis. Among the air quality measuring stations in the Gimhae regions, the PM10 concentration of the Sambangdong station was higher than that of the Dongsangdong station. Also, an examination of the relationships between PM10 concentration and meteorological elements showed that the greater the number of yellow dust occurrence days was and the lower the temperature and precipitation were, the higher the PM10 concentration appeared. Furthermore, a cluster analysis through the HYSPLIT model showed that there were 4 clusters of trajectories that flowed into the Gimhae region and most of them originated in China. The meteorological characteristics of the four clusters were analyzed and they were similar to those of the air masses that influence South Korea. These analyses found that meteorological conditions affect the PM10 concentration.

        In this study, eight episode days of high-concentration PM10 occurrences in the Gimhae region between 2006 and 2011 were analyzed. Most of them appeared in winter and the highest concentration was observed around 12 LST. Furthermore, the wind direction, wind velocity, and temperature elements were compared with observed values to verify the WRF numerical simulation results used in this study, and they simulated well in accordance with the trend of the observed values. The wind was generally weak in the high-concentration episode days that were chosen through surface weather chart and the numerical simulation results for wind field, and the air pollutants were congested due to the effects of the resulting local winds, thereby causing a high concentration of air pollutants. Furthermore, the HYSPLIT model was performed with the WRF numerical simulation results as input data. As a result, they originated from China and flowed into Gimhae in all eight days, and the lowest concentration appeared on the days when recirculation occurred.

        The purpose of this research is to distinguish the quantitative determination of phytochemicals in various agricultural products and to optimize an HPLC method for the determination of lycopene, lutein, α-carotene, β-carotene, and cryptoxanthin. Among the different conditions studied, the most suitable ones for our samples were the extraction with hexane/acetone/ethanol (50:25:25, v/v/v), dissolution of the dry extract in tetrahydrofuran/acetonitrile/methanol (15:30:55, v/v/v), injection on a C18 column with methanol/acetonitrile (90:10, v/v) + triethylamine 9 μM as mobile phase, and λdetection=475 nm. The mean percent recovery for the HPLC method were 120.7±4.1% (lycopene), 89.2±3.5% (lutein), 91.2±2.9% (α-carotene), 99.1±4.4% (β-carotene), and 100.0±5.3% (cryptoxanthin). The contents of lutein in the agricultural products were spinach, kiwi, tomato, blueberry, melon, respectively. However, the lycopene contents were the highest in the Black tomato (56.66±7.48 mg/kg) and Jangseong tomato (50.28±5.42 mg/kg). The concentration of β-carotene in all of the agricultural products ranged from 0.07 mg/kg to 65.03 mg/kg. The quercetin content of the agricultural products increased in the order of blueberry (986.57∼1,054.06 mg/100 g), kiwi (44.96∼55.09 mg/100 g), hallabong (31.92∼35.60 mg/100 g), and tomato (26.38∼34.94 mg/100 g). The highest kaempferol content was found in the blueberry (47.79∼76.15 mg/100 g) with results in all of the tested samples varying between 6.54∼48.11 mg/100 g. The total polyphenol contents of the various agricultural products increased in the blueberry (213.60∼229.96 mg/100 g), spinach (112.50∼141.67 mg/100 g) and kiwi (46.49∼70.44 mg/100 g). The total flavonoid content was the highest in both blueberry and spinach. Vitamin C content was detected in kiwi > hallabong > tomato > blueberry, respectively. The total anthocyanin contents (TAC) was detected in the Damyang blueberry and the imported blueberry.

        We analyzed the surface changes in each forest type based on multi-temporal satellite imagery and climate data analysis on the mountainous regions of Gangwon-do as the case study. As a result of forest type classification using satellite imagery, the area of coniferous forests was decreased, but the area of deciduous forests and the mixed forests were increased. The annual mean temperature in the study area generally risen, and the rise in the annual mean temperature in Wonju particularly displayed a notable rise in 1992. Temperature change in the seasons resulted in a greater rise rate in winter and autumn, compared to other seasons. Such annual mean temperature rise affected the change in forest type distribution, thus directly and indirectly affecting the decrease in the surface area of coniferous forests, and also greatly affecting the expansion of distribution and the growth of mixed forests and deciduous forests. The surface change analysis of each forest type using the post-classification comparison method showed considerable change from coniferous forests to deciduous forests and mixed forests, as a result of the change in forest type based on the increased annual mean temperature after 1990. Furthermore, the change in deciduous forests significantly occurred in mixed forest regions. With these results, future forest type data are expected to be used as the main index of climate change vulnerability assessment, and more accurate quantitative results are expected to be deduced with the assessment of other climatic elements and relationships with different forest types.

        최근 들어 안정된 수자원 확보를 위해 하천수를 강변의 충적층을 통과시켜 취수하는 강변 여과수 개발이 각광을 받고 있다. 지표수 및 지하수와 반응하는 주변 충적층 퇴적물에 존재하는 철은 강변 여과 후 양수정을 통해 얻어지는 지하수의 수질을 결정하는 데 매우 중요한 요소이다. 본 연구에서는 퇴적물-지하수-지표수의 상호 작용에 의한 철 화학종의 존재 변화를 알아보기 위해 창원시 대산면 낙동강변의 강변여과 부지에서 채취한 대수층 퇴적물 내에 존재하는 철 함유량을 퇴적물 심도 및 입자 크기에 따라 다양한 화학적 철 추출법을 통해 비교하였다. 실험 결과는 전체적으로 지표로부터 20 m 부근까지는 2가철 및 총 철 함량이 전체적으로 감소하다 20 m 깊이 이하에서는 증가하는 경향을 나타내었다. 이러한 결과는 육안으로 관찰되는 퇴적물 색깔이 지시하는 산화/환원 환경 특성과도 일치하였다. 한편, 퇴적물의 모래 부분보다 미사/점토 부분에서 추출법에 따라 2~10배의 철이 추출되었다. 그리고, 다양한 추출법 중 DCB 용액에 의해 가장 많은 철이 추출되었다. 이와 같은 다양한 철 분석법으로 추출되는 철 함량 특성은 퇴적물 내에서 철의 용해 및 침전을 결정짓는 심도에 따른 산화/환원 조건의 좋은 지시자로 활용될 수 있을 것으로 판단된다.

        The aim of the research was to analyze programs, outcomes, promotion process, and operation methods of neighbourhood making to provide basic information for progressive improvement directions in the future. Buk-gu in Gwanju city, samdeok-dong in Daegu city and dongpirang in Tongyeong city were selected for a comparative analysis. The main bodies of neighbourhood making for promoting a local amenity were analysed for this research. The results indicated that a voluntary and continuous participation of residents was expected in the case of neighbourhood making led by the residents. However, a steady budget support from the outside was necessary for the continuous management and improvement of neighbourhood organization. For this, a voluntary agreement was required through the consultative group and committee formation. The member of civil organization has a limitation in the ability to develop and maintain continuos activities in the case of neighbourhood making led by a civil organization. This research found that operation methods including the constant checking, the search for new ideas through assessment of the resident's participation, local festivals for a community formation and real satisfactions of residents' desires were needed in the neighbourhood making led by a civil organization. A participation rate in neighbourhood making was low in the case of neighbourhood making led by administrative bodies. This result indicated that the long-term strategics for space renewal and community revitalization were important. Various easy ways of residents' participation to reflect their interests and operation systems were also needed. Finally, current local issues, active residents' participation and residents' opinions would be included in the process of neighbour making in the future.
