  • From June 1987 to December 1994, 372 patients underwent operation for resection of esophageal cancer, and 48 patients with metastasis to distant abdominal lymph nodes were analyzed.. The primary tumors were located predominantly in lower thoracic esophagus(n=29). The location of involved lymph nodes were celiac L/N(n=45), common hepatic L/N(n=4), paraaortic L/N(n=l), and retropancreatic L/N(n=l). Most tumors penetrated the esophageal wall(T3,T4, n=43), metastased to regional L/N(N1, n=41), but a few tumors were limited to the esophageal wall(T1,T2, n=5), metastased to distant abdominal L/N without metastasis to regional L/N(NO, n=7). Resectability rate was 87.5%(42/48), and complete resection was possible in 31 patients(64.6%). The most frequent cause of incomplete resection and unresectability was unresectable T4 lesions(n=8), extranodal invasion(n=7). Overall operative mortality and morbidity was 4.2%, 22.9%, and resection mortality was 4.8%. Adjuvant therapy was given to 27 patients, and postoperative follow-up was possible in all patients(median follow-up, 32 months). The 1 year and 3 year survival for resection group was 54.0%, 18.1%(median, 386 days) including operative deaths. Our results suggest that resection of the esophageal cancer with metastasis to distant abdominal lymph nodes(M1LYN) can be done with acceptable mortality and morbidity, and may playa role in long-term survival in carefully selected patients because prognosis is dismal in unresectable esophageal cancer. We recommend that lymph nodes around celiac axis be dissected thoroughly for exact staging and possible prolongation of survival, and multimodality therapy as necessary because most patients with M1(LYN) esophageal cancer do poorly with only primay surgical treatment.

  • The purpose of this study was to establish the critical limit at CCP (Critical Control Point) of HACCP (Hazard Analysis Critical Control Point) system for instant noodle and it was conducted at P company in Ichen(Gyeonggi-do), Korea. According to the CCP, Fried process were experimented to removal and decrease of microbiological and chemical hazards by measuring of each temperature and times. As a result, the standard plate count and pathogenic microorganism were not detected by fried processing (Temperature : $145{\pm}10^{\circ}C$, Time : $75{\pm}30$ sec). The acid value of chemical hazards produced by fried processing was able to manage, showed lower (0.2) than the legal limit (0.6). Air-borne bacterial examination results detected(3 CFU/mL, 3 CFU/mL) in the Frying Room and Steam Room. Therefore, the CCP-BC of fried process would be a great alternative to prevent and remove hazard analysis, such as general and pathogenic microorganism (E. coli O157:H7, B. cereus, Listeria monocytogenes, Salmonella spp, Sthaph. aureus etc), chemical hazard analysis. In conclusion, it suggested that HACCP plan was necessary for management standard and systematic approach in establishement of critical limit, solving the problem, method of verification, education and records management by fried processing.

  • This study draws the following conclusions about the nature garden culture with crane that is a dynamic landscaping factor introduced into nature garden by analyzing the literatures on cranes written and landscapes painted in Chosun Dynasty. First, crane symbolizes such Buddhist, Taoist and Confucius media as appearance of Buddha, desire for Taoist hermit world and long life, and a solitary's life of proud loneliness. It has been recorded that crane was raised from the Three Nations Era till the Japanese occupation and Confucius scholars in Chosun Dynasty opened shows concerning crane or formed literature groups enjoying poems of it, and often using crane as their denial of going into government service. Second, in order to introduce crane to nature garden, people caught wild crane and made a fence and some kind of pond for their growth. In addition, crane was strictly managed by appointed slaves and they trained crane for dancing and then tended to allow a crane to play on the yard in terms of abstract meaning or got two cranes free in consideration of their ecology. Third, for more appreciation of crane and the expression of some symbolism matching for it, both plum and pine, which mean a solitary's life and long life respectively, were planted in nature garden. And, Confucius scholars in Chosun Dynasty also enjoyed their refined tastes with appreciation, napping, reading and playing the harp, accompanied by crane. As aforementioned, Confucius scholars in Chosun Dynasty did not only draw the meaning symbolized by cranes and write poems about such symbolic meaning, but also positively introduce crane into nature garden as a dynamic landscaping factor, so that they enjoyed synesthetic senses including looks, motions and sounds of cranes for their refined tastes.

  • 한국농어촌공사가 관리하고 있는 농업용저수지는 총 3,377개로 2015년 평균 저수율은 61 %를 기록하였는데, 이는 예년 평균 저수율51 %를 나타내고 있다. 1990년대 후반부터 우리나라에는 기후변화에 따른 온난화 추세를 나타내는 경향을 보이고 있고, 강수량 및 집중호우의 증가추세도 나타나고 있다. 기온과 강수량이 과거와 다른 변화를 보임에 따라 물 공급의 안정성을 확보하기 위해 저수지를 통한 수자원 확보가 이루어지고 있으나, 용수공급능력이 어떻게 변화할 것인지에 대한 정보가 부족한 상태이다. 또한, 논벼의 생육에 있어서 저수지의 적절한 용수공급은 필수적이기 때문에 저수지의 효율적 운영 및 용수이용의 효율적 분석이 필요하다. 최근까지 연구 조사에서 농업용수 이용 효율은 굉장히 낮은 것으로 나타났다. 농업용수 이용 효율의 개선을 위해서는 용수수급 특성을 조사 분석하고, 이에 따른 개선방안을 제시하는 것이 필요하다. 본 연구에서는 가뭄 등 기상 재해에 대응하고 한정된 농촌용수를 합리적으로 관리하기 위해 대상지구에 대한 농업용수 이용 효율성을 분석하고자 한다. 대상지구는 경기도 화성의 버들저수지 관개지구, 중북 진천의 무수저수지 관개지구의 필요수량과 공급수량을 비교하였다. 필요수량은 HOMWRS를 이용하여 산정하였고, 공급수량은 해당지구의 저수지 운영일지, 양수장 가동일지를 바탕으로 산정하였다. 버들저수지 관개지구의 2008년~2015년 필요수량 및 공급량을 분석한 결과, 필요수량 산정량과 실제 공급수량의 비는 최대 230%에서 최소 110%을 나타냈고, 2008년~2010년의 경우 약 220% 이상의 관개수량이 공급된 것으로 조사되었다. 2014년 및 2015년의 경우 전국적인 극심한 가뭄의 영향으로 필요수량 대비 공급량이 90%정도로 낮아졌으나 공급량 부족은 발생하지 않은 것으로 나타났다. 무수저수지 관개지구의 2008년~2015년 필요수량 및 공급량을 분석한 결과, 공급량과 필요수량의 비는 최소 170%에서 최대 250%로 나타났다. 특히, 2013년도에는 약 250%의 관개수량이 공급되어 초과공급량이 가장 많이 발생하였고, 분석기간 대부분의 년도에서 모두 약 200% 이상이 공급된 것으로 나타났다. 본 연구와 비슷한 지역의 2010년~2015년의 연구 결과를 보면, 경기도 이동지구를 대상으로 공급량과 필요수량의 비는 170%를 공급하는 것으로 나타냈으며, 충북 백곡지구는 210%를 공급한 것으로 나타났다. 본 연구 대상지구의 필요수량 대비 공급량은 과거의 연구와 비슷한 공급율을 보였다. 그러므로 앞으로 극심한 가뭄에 대비하기 위한 효율적인 농업용수 관리방안을 수립할 필요가 있는 것으로 판단된다.

  • 이상치는 표본자료에서 크게 어긋나 다른 자료들로부터 떨어져 표시되는 자료로써, 실제로 발생할 확률이 매우 낮은 자료로 정의되고 있다. 설계홍수량을 산정하기 위하여 적용하고 있는 극치계열의 연최대치 강우자료에는 기계오작동 및 엔지니어의 표독오류가 발생하고 있으며, 기후변화에 따른 거대태풍 및 국지적인 집중호우 발생 등으로 인한 극치값 등에서 이상치가 관측되고 있다. 통상 이상치들은 통계분석시 자료 본연의 특성을 왜곡시켜 편향된 결과를 산정할 수 있으므로 빈도해석시 이상치해석 절차를 수행하여 자료의 적정성을 확인하여야 한다. 현재 실무에서는 설계홍수량 산정요령과 하천설계기준 해설 등에서 관련 내용을 기술하고 있지만, 국내 강우자료의 기록연수의 부족으로 인하여 빈도해석시 이상치 해석이 미수행되고 있어 이상치에 따른 자료편의가 발생하면 결과물인 확률강우량이 왜곡되게 산정될 수 있다. 따라서, 본 연구에서는 국내 주요 도시의 강우자료를 이용하여 이상치검정을 수행하였다. 대상지점으로는 서울, 부산, 대전, 대구, 인천, 광주, 울산 등의 비교적 긴 관측년수를 보유하고 있는 광역시를 선정하였으며, 지속기간은 10분, 1~24시간의 25개 강우자료를 적용하였다. 이상치검정 방법으로는 타 방법에 비하여 이상치 검정력이 뛰어난 것으로 알려진 2가지 방법을 채택하였으며, 표본자료의 평균과 표준편차로 표준화된 z값을 이용하여 상 하 한계선를 초과하는 값을 확인하는 z-Score 방법중 향상된 중위수 절대편차(MAD)에 의한 수정 z-Score 방법(Hoaglin, 1993)과 Box-Plot 방법(Tukey, 1969)을 적용하였다. Box-Plot 방법(Tukey, 1969)은 전체 자료를 25%씩 사분위로 구분하는 방법으로 정렬된 자료계열을 중앙값, 박스, 수염(whiskers), 이상치로 구분한다. 정렬된 25~75% 값들을 박스로 포함하여 외곽의 수염값들을 이상치로 분류하며, 특히 사분위수의 도식화로 데이터의 분포를 파악하기 좋으며, 이상치들의 위치와 자료의 비대칭 여부를 쉽게 파악할 수 있다. 본 연구의 수행으로 수정 z-Score 방법의 경우에는 서울과 대구지점에는 이상치가 없으며, 부산지점에는 13개, 대전지점 7개, 인천지점 5개, 광주지점 32개, 울산지점 26개가 나타났다. Box-Plot 방법으로는 서울지점 35개, 부산지점 39개, 대전지점 32개, 대구지점 38개, 인천지점 51개, 광주지점 61개, 울산지점 65개의 이상치가 분석되었다. 연구를 수행한 결과, 수정 z-Score 방법에 비하여 Box-Plot 방법에 의한 이상치가 더 많이 발생하였으며, 각각의 방법으로 지속기간 및 연도별 이상치 발생자료를 확인하였다. 방법별 이상치 발생현황 등을 분석하여 지점별 발생횟수를 분석하였으며, 추후 지점 및 자료의 보완이 수행되면 활용성을 증대시킬 수 있을 것으로 판단된다.

  • Recently crosshole seismic tomography has come to be widely used especially for the civil engineering, because it can provide more detail information than any other surface method, although the resolution of tomogram will be inevitably deteriorated to some extent due to the limited wavefield aperture on the nonuniqueness of traveltime inversion. In addition, our field sites often consist of a high-velocity bed rock overlain by low-velocity rock, sometimes with a contrast of more than 45 percent, and furthermore the bed rock is folded. The first arriving waves can be then the refracted ones that travel along the bed rock surface for some source/receiver distances. Thus, the desirable first arrivals can be easily misread that cause severe distortion of the resulting tomogram, if it is concerned with (straight ray) traveltime inversion procedure. In this case, comparision with synthetic data (forward modeling) is a valuable tool in the interpretation process. Besides, abundant information is contained in the crosshole data. For instance, examination of tube waves can be devoted to detecting discontinuities within the borehole such as breakouts, faults, fractures or shear zones as well as the end of the borehole. Specific frequency characteristics of marine silty mud will help discriminate from other soft rocks. The aim of this paper is to present several strategies to analyze and interpret the crosshole data in order to improve the ability at first to determine the spatial dimensions of interwell anomalies and furthermore to understand the underground structures. To this end, our field data are demonstrated. Possibility of misreading the first arrivals was illustrated. Tube waves were investigated in conjunction with the televiewer images. Use of shot- and receiver gathers was examined to benefit the detectabilities of discontinuities within the borehole.

  • To find out the wood species used in national wood structures in the late Joseon Dynasty, 11 volumes of Yeonggeon-Uigwes were reviewed. It was confirmed that the wood was mainly used for the repair and restoration of palaces, shrines, and fortresses. In the 17th to 20th centuries, the wood species specified in Yeonggeon-Uigwes have revealed either hardwood or softwood. As hardwood species, Juglans mandshurica, Zelkova serrata, Fraxinus rhynchophylla, Betula schmidtii, Paulownia coreana, or Quercus spp. (Quercus aliena; Q, variabilis; Q, dentata; Q, acutissima; Q, mongolica; Q, serrata) were used. As softwood species, Pinus densiflora and Pinus koraiensis were used. Investigation of the wood species is important part because the same species is required as a principle when reparing cultural heritage. In this study, the anatomical images of the wood species were investigated for some samples which were taken from the same species that has been stored in the wood specimen room of the National Institute of Forest Science, instead of the actual wood material used. It was possible to find out the wood species of each member in the wooden cultural heritage buildings by reviewing the Yeonggeon-Uigwes in the late Joseon Dynasty, and the anatomical images of the wood species required for determining the wood species in the repair or restoration of the buildings.

  • Obtaining delivery addresses from calls is one of the most important processes in TV home shopping business. By automating this process, the operational efficiency of TV home shopping can be increased. In this paper, a method of recognizing and validating road name address, which is the address system of South Korea, from speech oriented text is proposed. The speech oriented text has three challenges. The first is that the numbers are represented in the form of pronunciation. The second is that the recorded address has noises that are made from repeated pronunciation of the same address, or unordered address. The third is that the readability of the resulted address. For resolving these problems, the proposed method enhances the existing address databases provided by the Korea Post and Ministry of the Interior and Safety. Various types of pronouncing address are added, and heuristic rules for dividing ambiguous pronunciations are employed. And the processed address is validated by checking the existence in the official address database. Even though, this proposed method is for the STT result of the address pronunciation, this also can be used for any 3rd party services that need to validate road name address. The proposed method works robustly on noises such as positions change or omission of elements.

  • This study examines the types of gods worshiped in the homes of Utsunoya village, the places where they are enshrined, the rituals and food offered to the gods, the decorations during the rituals, and the people's beliefs. Also, by comparing the gods worshiped in houses in remote Utsunoya with those of downtown Shizuoka, the differences and changes in the gods worshiped in the two contemporary spaces were predicted. Today, the gods enshrined in Utsunoya's houses are amatelaseu oomikami (天照大神), ancestor, ebisu, daigoku, kojin, inari, the god of the toilet, the god of land, and the god of water. From December 31st to January 3rd and on January 15th, Obon (July 15th), October when there is a festival at the village shrine, and on Ebisu Day (October 19th and 20th), residents offer drinks and food to the gods. Japanese beliefs at home are polytheistic in nature. They maintain national identity through kamidana and maintain family identity through ancestor worship linked to the Buddhist altar. The Japanese beliefs at home are firmly established in the background of the home, the base of family life. Japanese houses have a strong character as a religious space where they coexist "with the gods," and the residents have a cultural tradition of living with the gods.

  • Stamps are the smallest image symbols that can be read in the period, and they include the history, culture, politics, and figures and events of the issuing country. In particular, the stamps of the past presidents include the contemporary history of Korea, and reexamining and reviewing the meaning of the presidential stamps historically has a meaning that can not be overlooked as a researcher who studies the image of political leaders. In this study, the scope of research from the first republic to the fifth republic, where the publicity of political leaders through the advertisement of stamps and placards was high, was conducted and the leader image formation and change process centering on the former presidents Rhee Seungman, Park Jeong Hee, Chun Doo Hwan, Respectively. For the interpretation of the image of political leaders according to the changes of time, the images were classified by using Osgood's Semantic Differential Scale, and the images were analyzed using Saussure's semiotics. The image continues to move and change, and the conclusion that the image of the political leader of the time is not a simple personal image but a social product reflecting the specific age of the era.
