  • Background and Objectives: Adenoid cystic carcinoma (ACC) is a unique tumor characterized by frequent and delayed distant metastasis (DM) with uncommon regional lymph node metastasis. We evaluated the factors affecting DM of ACC and survival after appearance of DM. Materials and Methods: Medical records, radiographs and pathologic slides were reviewed for 94 patients from 1979 through 2001. Results: DM of ACC occurred in 46 patients, and developed more frequently in patients with tumors of the solid histologic subtype than in patients with tubular or cribriform subtypes. DM occurred less frequently in the sinonasal tract, and development of DM was not affected by tumor stage. Disease-specific 5- and 10-year survival rates were 88% and 72% for patients without DM, respectively and 76% and 48% for those with DM(p=0.02). Regarding the site of DM and its impact on outcomes, 30 patients had lung metastasis alone, 5 patients bone metastasis alone and 6 patients developed both lung and bone metastasis. Median survivals after appearance of DM among patients with isolated lung metastases and those with bone metastases with or without lung involvement were 54 and 21 months, respectively (p=0.04). Conclusions: Development of DM in ACC is predicted by solid histologic subtype, and major salivary gland or oral/pharyngeal rather than sinonasal primary site. Those patients with bone involvement with our without lung metastases had worse outcomes than those with pulmonary metastasis only.

  • 중국의 음식문화를 역사적으로 분류하여 올바르게 이해해 보고자 본 연구는 기존의 서적을 중심으로 고찰하여 보았다. 중국을 역사적 시대별로 태고, 중고, 근고, 중세, 근세, 현대로 나누어 살펴본 결과 중국의 식문화는 왕조의 흥망에 따라 많은 변화를 가져 왔으며, 서역의 식재료 유입과 자연의 영향으로 남북으로 주식의 형태가 나눠지게 되고, 테이블과 의자가 유입되어 입식문화가 정착하게 되면서 밥과 국은 개인전용 공기를, 부식은 큰 공용의 식기를 사용하여 제공되는 등 상차림의 변화가 나타났다. 근세(근세)에 들어서는 중국요리가 서방에 전달되기도 하였으며, 제비집과 상어지느러미, 해삼류 등이 고급음식으로 애용되었고, 조리법이 요즘의 요리와 아주 흡사하였다. 젓가락으로 밥과 부식물을 먹고, 숟가락은 국 전용 도구로 받아들이는 등 취식 도구의 사용 또한 현재의 모습을 지니고 있었다. 중국인들의 음식 문화에는 음양오행이라는 우주 만물의 원리가 항상 내재되어 있고, 유교, 불교, 도교의 철학적 사상이 상당히 깊이 내재되어 있음을 알 수 있다. 그래서 중국의 다양한 음식문화의 고찰은 같은 한자와 종교의 영향을 받은 한국, 중국, 일본의 명절음식을 종교와 연관지어 각 국가의 음식문화에 미친 후속 연구로 이어지길 바란다.

This study investigated 889 subjects, and at each corresponding age, who were collected among the trainers at the Civil Defense Training Institute in K-ku, Incheon City. The data collection period lasted from April to July of 2003. I revised and complemented the measurement tool for the Health Improvement Life Style developed by Jung Eun-Kyung. For analysis of the acquired data. I used SPSS11.0 program. The study shows that the Health Improvement Action of a group of middle aged men averaged 2.80, and 0.44 point out of 5. According to the results found during the analysis of the generic characters of differences in behaviors of Health Improvement. It was revealed that there were significant differences in age, regular exercise and health interest, stress management, self-concept as well as degrees of interest in health, and education level. According to monthly income levels, regular exercise and degrees of self-concept degrees were significantly different from each other. According to marital status. balanced diet and regular exercise were related to each other. According to religion, balanced diet, stress management degree, self concept degree, and degrees of interest in health, significant differences were shown. Based on the earlier mentioned results, we should pay attention to act more, rather than merely recognize the development of the health improvement program of our regional community. Also, it is necessary to find out the cause, which lowers men's interest in health.

  • Pollution of chloride ion-reinforced concrete can trigger active corrosion processes that reduce the useful life of structures. Multifunctional materials used as a counter-electrode by electrochemical techniques have been used to rehabilitate contaminated concrete. Cement-based pastes added to carbonaceous material, fibers or dust, have been used as an anode in the non-destructive Electrochemical Chloride Extraction (ECE) technique. We studied the performance of the addition of Carbon Fiber (CF) in a cement-graphite powder base paste used as an anode in ECE of concretes contaminated with chlorides from the preparation of the mixture. The experimental parameters were: 2.3% of free chlorides, 21 days of ECE application, a Carbon Fiber Volume Fraction (CFVF) of 0.1, 0.3, 0.6, 0.9%, a lithium borate alkaline electrolyte, a current density of $4.0A/m^2$ and a cement/graphite ratio of 1.0 for the paste. The efficiency of the ECE in the traditional technique using metal mesh as an anode was 77.6% and for CFVF of 0.9% it was 90.4%, with a tendency to increase to higher percentages of the CFVF in the conductive cement-graphite paste, keeping the pH stable and achieving a homogeneous ECE in the mass of the concrete contaminated with chlorides.

  • Purpose: The use of 18F-2-deoxy-2-fluoro-D-glucose positron emission tomography-computed tomography as a routine preoperative modality is increasing for gastric cancer despite controversy with its usefulness in preoperative staging. In this study we aimed to determine the usefulness of preoperative positron emission tomography-computed tomography scans for staging of gastric cancer. Materials and Methods: We retrospectively analyzed 396 patients' positron emission tomography-computed tomography scans acquired for preoperative staging from January to December 2009. Results: The sensitivity of positron emission tomography-computed tomography for detecting early gastric cancer was 20.7% and it was 74.2% for advanced gastric cancer. The size of the primary tumor was correlated with sensitivity, and there was a positive correlation between T stage and sensitivity. For regional lymph node metastasis, the sensitivity and specificity of the positron emission tomography-computed tomography were 30.7% and 94.7%, respectively. There was no correlation between T stage and maximum standardized uptake value or between tumor markers and maximum standardized uptake value. Fluorodeoxyglucose uptake was detected by positron emission tomography-computed tomography in 24 lesions other than the primary tumors. Among them, nine cases were found to be malignant, including double primary cancers and metastatic cancers. Only two cases were detected purely by positron emission tomography-computed tomography. Conclusions: Positron emission tomography-computed tomography could be useful in detecting metastasis or another primary cancer for preoperative staging in gastric cancer patients, but not for T or N staging. More prospective studies are needed to determine whether positron emission tomography-computed tomography scans should be considered a routine preoperative imaging modality.

  • DMT 시험은 연약지반의 공학적 특성을 파악하기 위한 현장 시험방법으로, 이 방법으로부터 구한 비배수 전단강도는 가장 신뢰성 있고 유용한 매개변수로 알려져 있다. 그러나 국외 다른 지역의 자료를 토대로 기존에 제안된 상관관계식들은 지역적인 특성에 의존한다. DMT 시험 결과는 3가지 중간 지수 - 재료지수, 수평응력지수, dilatometer modulus를 사용하여 해석이 이루어지며 특히 비배수 전단강도는 수평응력지수만을 이용하여 예측하고 있다. 본 논문에서는 먼저 DMT 시험의 국내 연약지반에서의 적용성을 살펴보았으며 DMT로부터 비배수 전단강도를 추정하기 위하여 $p_0, p_1, p_2, {\sigma '}_v$ 그리고 초기 간극수압을 바탕으로 인공신경망 모델을 개발하였다. 인공신경망 모델은 오차 역전파 알고리즘을 적용하였으며 국내 연약지반에서 수행된 DMT 시험 자료를 이용하여 훈련하였다. 인공신경망 모델의 적용성을 판단하기 위하여 훈련에 이용되지 않은 자료로부터 예측된 결과와 기존에 제안된 상관관계식으로부터 얻은 결과를 서로 비교하였다.

  • The purpose of this study is to contribute to the development of the women's fashion field with the goal of creating creative and experimental fashion styles through the categorization of cases of women's fashion design expressed with Maximalism, a type of expression used in modern fashion, as well as analyzing and examining the formativeness of this style. Qualitative research was conducted through a literature review and design case analysis. The scope of this research was from 2011 S/S to 2016 F/W, and the regional scope included the women's collections from Paris, Milano, London and New York. The results acquired are as follows. Initially, exaggeration was expressed through excessively exaggerating the overall silhouette of clothing or exaggeratedly distorting certain parts of the overall silhouette. Secondly, decoration was expressed through the use of the same colors and materials and the addition of excessive details and trimmings to express an exaggerated style of clothing as well as to express a luxurious and handcrafted style of clothing. Thirdly, fusion was expressed through integrating multiple items from different cultures, deconstruction, which destroys the concept of gender and use of clothing, and fashion style that transcends time and space. Fourthly, non-structurality was expressed through differentiating multiple weight feelings applied to the left/right sides of clothing or expressing a structural designs that is asymmetrical to the upper/lower/left/right directions to create a silhouette that displays a creative avant-garde style. As examined above, it was found that the maximalism expressed in fashion after 2011 created new images and expressed maximized emotional orientations through the exaggerated use of multiple silhouettes and decorations or through the integration of colors, patterns, ages and images. Through this process, maximalism is expected to not only provide an infinite possibility to the modern fashion that pursues diversification and multiplication, but also serve as an example that represents diversified post-modernism fashion trends in the future.
