Purpose : To investigate the causes of gastric wall shortening in ealy gastric cancer, upper gastrointestinalstudy was correlated with pathologic findings. Materials and Methods : We evaluated 41 cases (m:F=1.7:1, averageage=49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I;none,Grade II;intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumorinvasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, andmorphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wallshortening on upper gastrointestinal series. Results : Submucosal fibrosis was present in 4 cases in Grade I(n=21), 4 cases in Grade II (n=6) and 8 cases in Grade III (n=10), Positive conversing mucosal folds were seen in 5cases in Grade I (n=17), 0 case in Grade II (n=2) and 9 cases in Grade III (n=9), Gastric wall shortening wassignificantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (p=.0001and p=.002, respectively) Conclusion : Upper gastrointestinal finding of gastric wall protrusion in patients withearly gastric cancer should not misinterprete as advanced gastric cancer sine the finding could be a result ofsubmucosal fibrosis.

This experiment was conducted to investigate the optimum sowing date of northern type garlic in the central-northern part of korea. The sowing was carried out four times at intervals of 10 days from October 20 to November 20. There was no difference between the emergence rate from 85.6 to 90.3% and in the growth characteristics of the leaf by sowing date. There was no difference in the growth characteristics underground bulb by sowing date. Bulb weight was 25.1 ~ 8.8 g, bulb diameter 40.1 ~ 42.1 mm, bulb height was 33.6 ~ 34.7 mm, and the number of cloves was 6.1 ~ 6.3. Secondary growth rate was as high as 47.8 to 56.7% with no difference in sowing date. Significant difference between the time of sowing was not observed in the weight and length of the spathe. The yield and marketable yield has increased as the sowing period sooner.

This studies were conducted to develop cultivation methods on three Asclepiadaceae families( Cynanchum wilfordii Hemsley, C. auriculatum Royle ex Wight and Metaplexis japonica Makino) of which products are conventionally used as medicinal materials by analyzing plant growth. The variation of leaf weight of Asclepiadaceae families showed culmination point at August 15, and the stem showed highest growth on August 30. The root weight increased linearly during the growth. The days for sprouting was most shortened in the Cynanchum wilfordii as 18 days, and C. auriculatum, Metaplexis japonica followed after. The seed harvesting dates was Oct. 8 in the Cynanchum wilfordii, Oct. 23 in the Metaplexis japonica, and Nov. 1 in the C. auriculatum, respectively.

초피나무 종자의 전처리가 포장에서의 출아에 미치는 영향을 구명 하고자 노천매장과 NaClO 10% 등 7처리를 두어 생육 특성 을 분석하였다. 출아율은 노천매장 17.3%에 비해 GA3100 ppm과 NaClO 10% 처리 후 노천매장에서 각각 30.3%, 22.7%로 출아율이 향상되었으며 , 파종 후 26∼33일 사이에서 가장 높은 출아를 보였고, 이후 미미한 증가를 보였다. T/R율은 GA3 100 ppm전처리 후 노천매장에서 뿌리의 발달이 가장 양호하였다. To improve the percentage of field germination of Zanthoxytum piperitum DC., storage in ground(control) and several chemicals as treatments was investigated. Germination percentage was 30.3 and 22.7% in GA3(100 ppm) and NaCIO(10%), respectively compared with 17.3% in storage in ground without treatments. Germination percentage reached maximum between 26 and 33 days after seeding and then increased slowly. Top/Root ratio was the highest at storage in ground after the treatment of GA3 100ppm.

철도 보선장비는 선로의 건설 및 유지보수를 목적으로 제작되거나 구매하여 운용하고 있는 특수차량이며 차량의 구조나 안전시스템이 일반적인 차량과 다르게 구성되어 있다. 보선장비는 주로 열차가 차단된 시간에 안전이 확보된 구간을 주로 작업을 시행하기 위하여 운행하기 때문에 과속이나 열차조성의 잘못에 의한 탈선사고가 일어난 사례는 적다. 보선장비의 탈선사고는 주로 작업개소를 이동하기 위해 보선장비를 열차로 편성하여 열차다이아의 중간에 운행하는 과정에서 발생하고 있다. 보선장비의 탈선에 영향을 미치는 주요 인자는 과속, 잘못된 열차의 조성, 장비의 구조적인 특성을 고려하지 않은 최고속도, 선로에서의 궤도틀림, 장비의 정비불량 등이 복합적으로 작용하였을 때 발생되고 있으므로 이러한 요인이 탈선에 미치는 영향을 분석하고 재발 방지를 위한 대책을 제시하였다. Railway maintenance equipment is a special vehicle that is manufactured or purchased for the construction and maintenance of railways, and the structure and safety system of the equipment are different from general vehicle. Since the equipment operates when the regular trains are blockaded to secure the safe working area, there are few cases of derailment accidents due to speeding or wrong the train consist. The main derailment accident of the equipment occurs in the process that the equipment moves to the work place in the middle of the time tables of regular trains. The main factors affecting the derailment of the equipment are speeding, wrong train consist, maximum speed without considering the structural characteristics of the equipment, track irregularity, and poor maintenance of the equipment. And the complex interaction between these factors has caused the derailment accident. This paper analyzes the effects of these factors on derailment and suggests measures to prevent the recurrence of the accidents.

The concrete track is being used at the Phase Ⅱ of the Kyeongbu High Speed Railway and New Constructed Honam High Speed Railway. When it makes a decision of bridge type, It has to consider about longitudinal forces of Continuous Welded Rail, Displacement at the end of bridges, Up-lift forces for fastener on the track. If it is installed turnout on the bridge, There is likelihood of the deck twist by applying the each difference longitudinal forces at the 4 each rails and the buckling by concentration of rail stress at the turnout. Moreover, If it is installed turnout on the continuous bridge and REJ(Rail Expansion Joint) on the main track or turnout track. It is hard to keep a safety for rail because of coming to twist or folding at the expansion of deck on the turnout track. Therefore when it is a design of bridge with turnout. It need to take bridge type to minimize an additional axial force and a displacement at the turnout. This paper makes a study of the composite steel arch bridge that is able to resolve criteria requirements of safety for track with turnout and suggest a helpful design method for bridge considering track with turnout by being based on design and construction method of Eonyang Bridge at the north part of Ulsan Station in Phase Ⅱ of the Kyeongbu High Speed Railway.
