Preoperative gastroendoscopic and roentgenologic findings of stomach were evaluated in 231 cases of gastric diseases proven by the surgical intervention and histopathological examination. The results were as follows: 1) In the diagnosis of 175 cases of gastric cancer, correct diagnosis was made by gastroendoscopy in 82.3% and by rcentgenography in 81.6% significantly different statistically. And gastroendoscopy plus roentgenography permitted a correct diagnosis in 90% of the cases. The rate by which both gastroendoscopy and roentgenography for the diagnosis of gastric cander made diagnosis concomitantly was 78.6% in correctly diagnosed group and 8% in incorrectly diagnosed group, summing up the coincidence rate between two methods to 86.6%. 2) In the diagnosis of 31 cases of benign gastric ulcer, correct diagnosis was made by gastroendoscopy in 48.4% and by roentgenography in 67.7%, significantly different statistically. And gastroendoscopy plus roentgenography permitted a correct diagnosis in 74.2%. The rate of identical diagnosis by both gastroendoscopy and roentgenography for the diagnosis of benign gastric ulcer, on the contrary to gastric cancer, was 48.4% in correctly diagnosed group and 22.6% in incorrectly diagnosed group, making the coincidence rate of diagnosis by two methods in 71%. It is claimed at correct diagnosis for the brnign gastric ulcer from the above data that some other diagnositic methods like gastric output study and cytology of gastric juice are needed beyond the conventional gastroendoscopic and radiologic method, as with needs of expertise in both fields.

Enzyme histochemistry of the gastric surface epithelium has been found to be valuable in diagnosing atrophic lesions with intestinal metaplasia of gastric mucosa. And interest in intestinal metaplasia of gastric mucosa as the origin of gastric carcinoma has increased considerably. To identify the type of intestinal metaplasia of stomach in gastric cancer by direct measurement of surcrase activity from gastric mucosa, we conducted this study. We obtained following results; 1) Intestinal metaplasia in atrophic gastritis showed two types, small intestinal type (46.1%) and colonic type (53.9%). Which was judged by direct measurement of sucrease activities from gastric mucosa. 2)In remnant stomach small intestinal type of metaplasia was observed in 55.6%, and 16.6% of gastric mucosa in benign gastric ulcer showed small intestinal type of metaplasia. 3)In gastric cancer, 37% of non-tumor bearing mucosa showed samll intestinal type of metaplasia. Our results suggest that degree of differentiation of intestinal metaplasia has no direct relationship with malignant potential in stomach.

Intestinal lymphangiectasia is a disorder of small intestine, which is associated with dilation of intestinal lymphatics and leakage from ruptured lacteals to intestinal lumen of intestinal lymoh which contains plasma proteins, chylomicrons, and small lymphocytes. Congenital or primary intestinal lymphangiectasia is due to a malformation of lymphatic systems, whereas secondary intestinal lymphangiectasia is preceded by inflammatory or neoplastic disease and is also caused oy decrease in lymph flow from thoracic duct due to elevated pressure in the left subclavian vein, Recently we experienced a 23 year-old female patient with recurrent tetanic attacks and the features of protein-losing enteropathy confirmed by a1-antitrypsin clearance test. And with the aid of blind peroral jejunal biopsy we diagnosed her as having intestinal lymphangiectasia, showing dilated lymphatics in the lamina propria. So, we report the first adult case of intestinal lymphangiectasia confirmed by histologic findings in Korea, without apparent secondary cause.

분산 이기종 컴퓨팅 시스템의 성능은 입력 그래프인 방향성 비순환 그래프(DAG)를 스케줄링 하는 알고리즘의 성능에 따라 좌우된다. 그러나 분산 이기종 컴퓨팅 시스템에서의 태스크 스케줄링은 NP-complete 문제로 휴리스틱 방법으로 접근해야 한다. 태스크 스케줄링 알고리즘은 우선순위 결정 단계와 프로세서 할당 단계로 구성되며, 많은 연구들이 두 단계를 함께 고려하고 있다. 본 논문에서는 태스크 우선순위 결정 단계에 초점을 맞추어 태스크 복제 기반 프로세서 할당 방법에 최적화된 태스크 우선순위 결정 알고리즘인 WPD 알고리즘을 제안한다. 제안하는 WPD 알고리즘의 성능 분석을 위해 태스크 복제 기반프로세서 할당 방법을 사용하는 기존의 태스크 스케줄링 알고리즘인 HMPID, HCPFD, HCT 알고리즘의 프로세서 할당 단계에 본 논문에서 제안하는 WPD 알고리즘을 결합하여 성능을 비교하였다. 그 결과 본 논문에서 제안하는 WPD 알고리즘이 기존태스크 우선순위 결정 방법에 비해 태스크 복제를 더욱 효율적으로 사용하여 HCPFD 알고리즘보다 9.58%, HCT 알고리즘보다 1.31% 성능 향상이 있는 것을 확인하였다. The performance of DHCS depends on the algorithm which schedules input DAG. However, as the task scheduling problem in DHCS is an NP-complete problem, heuristic approach has to be made. Task scheduling algorithm consists of task prioritizing phase and processor allocation phase, and most of studies are considering both phases together. In this paper, we focus on task prioritizing phase and propose a WPD algorithm which is optimized for task duplication based processor allocation method. For an evaluation of the proposed WPD algorithm, we combined WPD algorithm with processor allocation phase of HMPID, HCPFD, HCT algorithms, which are using task duplication based processor allocation method. The results show that WPD algorithm makes a better use of task duplication than conventional task prioritizing methods and provides 9.58% better performance than HCPFD algorithm, 1.31% than HCT algorithm.

Background/Aims: Cytotoxin-associated gene (cagA) and vacuolating cytotoxin (Vac) production have been reported to be major virulence factors of Helicobacter pylori. We evaluated whether cagA genotype and Vac production might be correlated with gastroduodenal diseases in Korea and whether this correlation could be due to difference in proinflammatory cytokine expression and apoptosis of gastric epithelial cells. Methods: The presence of cagA gene and Vac production were examined after H. pylori was isolated from Korean patients. Gastric epithelial cells were infected with cagA+Vac+, cagA+Vac- or cagA-Vac- strains, and then, cytokine gene expression was evaluated using quantitative reverse transcription- polymerase chain reaction. Apoptosis and caspase-3 activation were measured in H. pylori-infected epithelial cells. Results: There was no significant correlation between the presence of those virulence factors in isolated H. pylori strains and peptic ulcer or gastric cancer. Upregulation of the cytokine gene expression, including interleukin (IL)-1α, IL-8, GM-CSF and monocyte-chemoattractant protein 1, as well as apoptosis and caspase-3 activation showed no difference due to the infection with cagA-positive and cagA-negative strains. Moreover, they were not correlated with the production of Vac. Conclusions: These results suggest that the non-correlation between virulence factors of isolated H. pylori strains and gastroduodenal disease entities in Korea is due to similar capacity in proinflammatory cytokine gene expression and apoptosis by each H. pylori strain infection.

항공 교통 상황 방송 서비스를 위한 중앙 집중형 TIS-B 서버 설계 및 구현

항공 수요가 지속적으로 증가함에 따라 레이더를 이용한 항공 감시가 한계에 다다르면서, 새로운 항공 감시 기술인 ADS-B가 등장하였다. ADS-B는 레이더에 비해 높은 위치 정확도와 빠른 갱신 주기를 제공하며, ADS-B 송수신기를 장착한 항공기간에는 서로의 위치 정보를 확인할 수 있다는 장점을 갖는다. 하지만 모든 항공기가 ADS-B 송수신기를 탑재하지는 않으며, 서로 다른 ADS-B 데이터 링크를 사용하는 항공기 간에는 위치 정보의 송수신이 불가능하다는 단점이 있다. 이러한 ADS-B의 단점을 해결하기 위해 레이더가 감시 중인 항공기의 정보를 방송하는 TIS-B 서비스와 ADS-B 데이터 링크를 교차하여 ADS-B 신호를 방송하는 ADS-R 서비스가 개발되었다. 본 논문에서는 ADS-B 감시 자료와 레이더 감시 자료를 통합하여 TIS-B 서비스와 ADS-R 서비스를 함께 제공할 수 있는 항공 교통 상황 방송 서비스용 중앙 집중형 TIS-B 서버를 설계하고 구현하였다. 구현한 시스템은 직접 구성한 ADS-B 지상 시스템과 연결하여, 비행 중인 항공기의 ADS-B 감시 자료와 레이더 감시 자료를 수신하고, 수신한 감시 자료를 이용하여 TIS-B 서비스와 ADS-R 서비스를 제공하기 위한 감시 자료를 생성하여 모의 방송을 하는 방법으로 검증하였다. As a radar based air surveillance hits the limit along with the growing air traffic needs, a new air surveillance technology called ADS-B has emerged. ADS-B provides more accurate position information with a shorter interval, and aircraft equipped with ADS-B transponders can check each other’s location. However not all aircraft are equipped with ADS-B transponders, and aircraft with different ADS-B data links cannot check each other’s location. To address these problems a TIS-B service, which broadcasts information that a radar is tracking, and an ADS-R service, which cross-broadcasts information of different ADS-B data links, have been emerged. In this paper, we design and implement a centralized TIS-B server for broadcasting air traffic situation which is capable of providing a TIS-B service and an ADS-R service at the same time. The implemented TIS-B server has been verified with a configured ADS-B ground system, by receiving ADS-B surveillance data and radar surveillance data followed by generating surveillance data for providing a TIS-B service and an ADS-R service and simulating broadcast of those generated surveillance data.

20세기 음성 자료에서 나타나는 체언 말 자음의 교체 현상

송인성 ( Inseong Song ) 민족어문학회 2016 어문논집 Vol.- No.76

이 연구는 20세기 음성 자료에 나타나는 체언 말 자음 /ㅈ, ㅊ, ㅌ, ㅋ, ㅍ/의 교 체 양상을 분석하여, 20세기 현대국어에서 체언 말 자음이 실현되는 양상을 살펴 본 것이다. 체언 말 자음이 실현되는 양상을 보다 명확하게 분석하기 위하여 세부 적으로 시기를 나누어 각 시기에 체언 말 자음이 교체되는 양상을 파악하였다. 그 결과, 체언 말 자음은 20세기 음성 자료에서 다양한 형태로 교체되는데, /ㅈ/ 말음 은 [ㅅ, ㅊ]로, /ㅊ/ 말음은 [ㄷ, ㅅ, ㅈ, ㅌ]로, /ㅌ/ 말음은 [ㄷ, ㅅ, ㅊ]로, /ㅍ/ 말음은 [ㅂ]로, /ㅋ/ 말음은 [ㄱ]로 교체되는 양상을 보였다. 이와 같은 현상이 시기별로 실 현되는 양상을 보았을 때, 20세기 전기에 해당하는 1920-30년대 자료에서 체언 말 자음이 다양한 교체형으로 실현되는 것이 특징적이다. 체언 말 자음이 주로 교체 되는 단어는 20-30년대 자료에서 ``빛``, ``꽃``, ``끝``이고, 20세기 전체 자료에서는 ``빚``, ``녘``, ``부엌``으로 나타났다. 체언 말 자음이 주로 표준형으로 실현되는 단어는 ``낮``, ``밑``, ``곁``, ``밭``, ``바깥``, ``앞``, ``옆``으로, 이 단어들은 시간과 장소의 의미를 지 닌 명사이고 생략이 잘 안 되는 처격 조사와 고빈도로 결합되는 사실을 확인할 수 있었다. The aim of this study is to investigate alternation of noun-final consonants /ㅈ, ㅊ, ㅌ, ㅋ, ㅍ/ in Korean of the 20th century using spoken language corpus(speech corpus). In order to analyze alternation aspects of noun-final consonants accurately, it was subdivided into six periods from 1920-30s to 1990s. As a result, noun-final consonants /ㅈ, ㅊ, ㅌ, ㅋ, ㅍ/ were changed into various alternations in 20th century data. /ㅈ, ㅊ, ㅌ/ were changed into [ㅅ] in entire 20th century. /ㅋ/, /ㅍ/ were changed into [ㄱ], [ㅍ] respectively in entire 20th century as well. /ㅊ/, /ㅊ, ㅌ/ were changed into [ㅈ], [ㄷ] in 1920-30s. /ㅌ/ was changed into [ㅊ] in 1960∼1990s. Words that noun-final consonants were mainly changed into alternations were ``빛``, ``꽃``, ``끝`` in 1920-30s and ``빚``, ``녘``, ``부엌`` in entire 20th century. However ``낮``, ``밑``, ``곁``, ``밭``, ``바깥``, ``앞``, ``옆`` were not mainly changed their coda in entire 20th century. Consequently, noun-final consonants have a large number of alternations in early 20th century Korean.
