  • There have been high demands for urban underground structures. However, they should be rapidly constructed while maintaining the functions of adjacent structures and road systems especially in urban areas. In this respect, trenchless excavation methods are considered to very effective in minimizing ground displacements during excavation works. A variety of field conditions such as economic, technical and environmental aspects should be taken into consideration when an optimum trechless excavation method is to be chosen in a given condition. Therefore, this study aims to carry out a fundamental study to select an optimum trenchless excavation method by the decision making technique. Especially, AHP (Analytic Hierarchy Process) which is a kind of a multiple attribute decision making process is adopted to consider the opinions of experts and to derive reliable decision criteria. As a result, the weights of key factors and the most effective trenchless methods for different ground conditions were proposed in this study.

  • 블루베리는 진달래 과(Ericaceae) 산앵도나무 속(Vaccinium)의 낙엽성 또는 상록성의 저수고성 또는 반교목성의 과수로, 뉴욕 타임즈가 선정한 세계 10대 장수식품의 하나로 알려져 있다. 우리나라에는 전부터 정금나무, 월귤나무, 모새나무, 산앵도나무 등이 자생하고 있으나, 경제적인 가치가 있는 종은 Vaccinium Cyanococcus로 북미지역에서 육성된 품종들이 들어와 재배되고 있다. 처음 도입된 해는 1965년경으로 지금도 40년 이상 된 나무들이 있고, 상업적으로 재배되기 시작한 것은 2000년이고 공식적인 연구는 2004년 국립원예특작과학원에서 시작되었다. 한국블루베리협회 소식지에 주기적으로 기록되기 시작한 재배면적은, 2007년 112ha, 2008년 217ha, 2009년 313ha, 2010년 534ha이었다가 2011년 1,082ha로 크게 증가하였다. 시도별 재배면적은, 전북이 254ha로 가장 많았고, 충남 186ha, 전남 169ha, 경북 157ha, 충북 118ha, 경기 90ha, 경남 58ha, 강원 47ha, 제주 4ha 순이었다. 특히 2010년부터 2011년까지 한 해 동안 블루베리 재배면적이 크게 증가한 것은 각종 언론매체에서 블루베리 기능성에 대한 홍보와 소비자의 인식 증가와 더불어 새로운 소득 작물로 농가 수요가 확대되었기 때문이다. 이는 블루베리 묘목의 수입이 2009년 327천주에서 2010년 702천주로 크게 증가한 것으로도 알 수 있다. 아울러, 국내로 수입되는 냉동과, 건조과의 수입량도 큰 폭으로 증가하였다. 냉동 블루베리 수입량은 2009년 812톤에서 2010년 4,700톤으로 대폭 증가하였는데, 주요 수입 국가는 미국(3,931톤), 캐나다(557톤), 프랑스(70톤), 태국(18톤), 중국(16톤) 등으로 주스 등 가공품 시장의 수요 증가에 따른 것이다. 건조 블루베리의 수입도 2009년 14톤에서 2010년 54톤으로 증가하였다. 2011년 국내산 블루베리 가격은 생과 1kg에 40,000~50,000원선이었으나 35,000원에 판매하는 농장도 있었고, 냉동과를 62,000원도 판매하는 농장도 있었다. 미국 오레곤 주에서 생산한 블루베리 생과가 금년 7월부터 91톤에서 227톤 정도 수입될 것으로 예상된다. 블루베리의 국내 생산량이 많아지고 수입까지 되면, 농업인들은 더욱 품질 좋은 과실을 생산하도록 노력해야 하고, 잼, 식초, 와인 등의 가공식품 외에 과자, 케익, 머핀 등 베이커리용으로 많이 소비되도록 하며, 지역의 다른 상품들과 연계하여 찾아가고 싶은 관광 개발 등으로 소비 촉진을 위해 고심해야 할 것이다.

  • In this paper, the channel preprocessor with an area-efficient architecture is proposed for the MIMO symbol detector which can support four transmit and receive antennas. The proposed channel preprocessor can shrink the channel dimension to reduce the hardware complexity of the MIMO symbol detector. Also, the proposed channel preprocessor is implemented with very low complexity by using QR decomposition (QRD) and log-number system (LNS). By applying QRD and LNS to the nulling matrix calculation block, the numbers of matrix-multiplications and matrix-divisions are decreased and thus the complexity of the proposed channel preprocessor is significantly reduced. The proposed channel preprocessor was designed in a hardware description language (HDL) and synthesized to gate-level circuits using 0.13um CMOS standard cell library. With the proposed channel preprocessor, the number of logic gates for channel preprocessor is reduced by 20.2% compared with the conventional architecture.

  • The HPcN (Hybrid & high Performance Convergence Network) in research networks means environment which can provide both computing resource such as supercomputer, cluster and network resource to application researchers in the field of medical, bio, aerospace and e-science. The most representative research network in Korea, KREONET has been developing following technologies through the HERO (Hybrid Networking project for research oriented infrastructure) from 200S. First, we have constructed and deployed a control plane technology which can provide a connection oriented network dynamically. Second, the integrated resource management system technology has been developing for reservation and allocation of both computing and network resources, whenever users want to utilize them. In this paper, a testbed network is presented, which is possible to reserve and allocate network resource using the integrated resource management system. We reserve network resource through GNSI (Grid Network Service Interface) messages between GRS (Global Resource Scheduler) and NRM (Network Resource Manager) and allocate network resource through GUNI (Grid User Network Interface) messages between the NRM (network resource manager) and routers, based on reservation information provided from a user on the web portal. It is confirmed that GUNI interface messages are delivered from the NRM to each router at the starting of reservation time and traffic is transmitted through LSP allocated by the NRM.

  • To explain the relationship between plant size and seed production, change of sexual organs, relationship between each organs of Convallaria keiskei population, which is located in Gwiyeo-2-ri, Namjong-myeon, Gwangju-si, Gyeonggi-do these were studied from April to August 2002. This study was carried out two ways. One way was to set up the permanent quadrat to explain the change of sexual organs. The other was to carry the collected sample to the laboratory and analysis it to explain the relationship between each organs and energy division of seed production. In the Convallaria keiskei population, the average number of leaf which blooming shoot in the permanent quadrat was 2 and I could find the late leaf size was larger. It was found that, per shoot, the average number of flower was 7.9, fruit was 5.4 and seed was 16.1. Each properties in the sexual organ, underground part size and leaf size, had correlation of 1% or within 5%. The flowering time of the Convallaria keiskei was from April 26 to May 11. Therefore, it can be estimated that the blooming period was $8{\sim}9$ days in just one flower. Among that flowers bloom at the beginning May, 80% fruit at the end of May, and 68% fruit at the end of August. The dry weight of seed had more correlation dry weight of underground part than leaf area.

  • In this paper, we investigated the shadow area of radio programs which are currently being broadcast via FM 102.5 MHz in Jeollabuk-do consisting of 6 cities and 8-guns. The field strength data of FM 102.5 MHz was used with criterion of shadow area. As a result, the field strength of the eastern mountainous area in Jeollabuk-do was very low. We also measured, compared and analyzed the field strength of 102.5 MHz(TBN-Jeonju), 100.7 MHz(KBS) and 99.1 MHz (MBC) in Jeollabuk-do. Based on the field strength data, we tried to find what correlation exists and how much influence is between difference of antenna output power and solution of shadow area. In result, enhancement of antenna output power is not solution in terms of reducing the shadow Area of 102.5 MHz(TBN-Jeonju). In addition, we measured, compared and analyzed the field strength of 102.5 MHz(TBN-Jeonju) and 106.9 MHz(EBS). In fact, the relay stations with 104.1 MHz, 104.9 MHz, 105.3 MHz and 107.5 MHz of EBS FM has a number of FM relay stations in the eastern mountainous area of Jeollabuk-do. As a result, we confirmed that EBS almost did not have shadow area in the eastern mountainous area of Jeollabuk-do based on the field strength data. As in the case of EBS and KBS, we suggest installing TBN-Jeonju FM relay station with the best solution to reducing the shadow area to extend the audible range of TBN-Jeonju.

  • Taxonomic studies on morphological, principal component analysis (PCA), palynological, RAPD and PCR-RELP analysis were conducted to intraspecific relationships of Rubus oldhami. Three types of Rubus oldhami based on the flower characters such as petal length and number were used in this study. Among the 14 morphological characters, perianth length, calyx lobe length, apical leaflet shape and leaflet length were used to distinguish for each type. The pollen characters such as shape, aperture number, surface sculpture were showed very similar among three types. Eight primers out of 20 arbitrary primers were screened for three types, and were revealed 33 ($60\%$) polymorphic bands. The phonogram by RAPD data showed incongruent with morphological analysis. Even though ten restriction endonucleases produced 20 restriction sites, polymorphic bands were not observed. Based on the results, three types of Rubus oldhami divided well by morphological characters, but pollen and DNA data were not supported. Therefore, type 1 and 2 which different from type 3 by flower characters considered as a temporary hybrid or ecotype because of their similar habitats.

  • This study targeted 4,572 middle-aged women to examine the relationship between nutritional status and dietary inflammatory index according to blood glucose level using data from the Korean National Health and Nutrition Examination Survey (KNHANES). Data were analyzed using complex survey chi-square, General Linear Model and logisitc regression in SPSS Win 25.0 program. Women with high blood glucose (normal blood sugar→diabetes) had high rates of obesity and blood TG/HDL-cholesterol ratio. On the other hand, the Mean Adequacy Ratio (10 nutrients) and the intake of anti-inflammatory foods: beans, seeds, mushrooms, and fruits, were lower in the diabetic category. When we analysed the association between blood glucose and the Dietary Inflammatory Index, the risk of pre-diabetes and diabetes was significantly higher in the most pro-inflammatory diet category (Q5) compared to the most anti-inflammatory diet category (Q1). These findings suggest that nutritional education emphasizing the intake of various foods should be effectively conducted effectively in order to improve blood glucose among middle-aged women.
