The medical records of 210 pat,ients with pathologically proved adenocarcinoma of resected stomach at St. Benedict Hospital in Busan, over 6 years from January 1986 to Decernber 1991, were reviewed. The cumulat.ive 5 year survival rates for various categories were ob- t.ained by statistical life survival analysis program of personal cornputer(SPSS). The overall cumulative 5 year survival rate was 38.4%, and the cumurative survival rate for various categories were 39.0% in male, 37.0% in female for 5 year, 50.0% in below 30 years, 55.9% in 4th decade, 35.7% in 6th decade, 36.5% in 7th decade, 28.6% in above 70 years for 5 year and 35.7% in 5th decade for 3 year, 96.2% in TNM stage I, 50.0% in st,age II, 31.4% in stage III for 5 year, and 11.4% in stage 1V for 2 year, 37.9% in antrum, 64.1% in body for 5 year, 16.7% in cardia 8: fundus for 2 year, 96.4% in Tl, 51.0% in '12, 15.1% in T3 for 5 year and 7.9% in T4 for 4 year, 60.0% in Borrmann type I for 2 year, 1.7.2% in type II, 22.8% in type III for 5 year and 33.3% in type 1V for 2 year, 76.:3 % in .'UO, 31.2% in N2 for 5 year, 13.6% in N2 for 3 year and 11.5% in N3 for 4 year, 47.5% in moderately differentiated type, 11.2% in poorly differentiated type and 45.5% in signet ring ccll t.ype for 5 year. Multivariate analysis of variables were done by means of multiple linear regression(C.'ox-r< gression) analysis. By this multivariate analysis, TNM stage(p=0.0000), dept,h of invasion(p =0,0032), nodal status(p=0.0089) were stat.istically valuable as prognostic factors. Ot.hcr variables were somewhat valuable as prognostic fact.ors in univariate analysis but not in multivariate analysis(Cox-regression). (Korean J Gastroenterol 1994; 26: 424 431)

Purpose: To compare 3D ultrasound (3D-US) with 2D ultrasound (2D-US) in terms of their usefulness and limitations in the diagnosis of breast masses. Materials and Methods: We obtained 2D and 3D US images of 37 breast lesions present in 20 cases of fibroadenoma, nine of cancer, and eight of fibrocystic disease proven in a total of 26 cases [fibroadenoma (n= 13), breast cancer (n= 9), fibrocystic disease (n=4)] by histologic examination, and by clinical evaluation and clinical evaluation with sonographic imaging in eleven. When comparing 3D and 2D-US images we had no prior information regarding detection rate according to the size of lesions, whether or not internal and boundary echo patterns could be interpreted, accurate differentiation between tumorous and non-tumorous lesions, or the accuracy with which benign and malignant tumors could be differentiated. Results: For lesions of 1 cm or less in diameter the detection rate of 3D-US was lower than that of 2D-US, but for lesions over 1 cm there was no difference between the two modalities. In fibroadenoma and breast cancer, 3D-US was more useful than 2D-US for the evaluation of both internal and boundary echo, but with fibrocystic disease and in the diagnosis of tumor/non-tumor, there was no significant difference. In breast cancer, however, 3D-US more accurately determined malignancy, and in fibroadenoma, because of the pseudospicule revealed by 3D-US, this modality was less exact in determining benignancy. Conclusion: In the evaluation of internal and boundary echo in breast mass diagnosis, 3D-US was more useful than its 2D counterpart. For lesions of 1 cm or less in diameter, however, the detection rate of 3D-US was low, and since in some benign cases a pseudospicule was apparent, the possibiliy of confusion with malignancy arose. For these reasons, the usefulness of 3D-US was limited.

본 연구의 목적은 소성영역에서의 철골 부재내에 존재하는 존재응력을 추정하는 법을 개발하기 위함이다. 여기에선 선행 실험 연구를 근거로 하여 응력집중 현상에 기인한 국부 소성화를 고려하여 보정계수법이 제안되었다. 구멍주위의 응력 분포를 파악하기 위하여 유한요소 해석을 수행하였고, 그 결과를 탄 소성역에서의 구멍내기법에 의한 결과와 비교하였다. 보정계수법을 적용한 결과, 본 연구에서 제안된 방법은 실재 초기 존재응력값과 약 2% 정도의 오차를 가진 매우 좋은 결과치를 나타냈다. The purpose of this study is to develop a method to deduce existing stress of steel member in inelastic range. Based on the previous experimental study, modified factor method considering the local plastification due to stress concentration was proposed. Finite element analysis was performed to investigate the stress distribution around hole and the results of the finite element analysis were compared with those from the Hole Drilling Method in elastic-plastic range. As a result of applying a modified factor method, proposed method shows very good approximation of 2% error for exact value of stress in the plastic range.

Objectives: Various problems are encountered during audiometric testing. Deviation from reference threshold levels for supra-aural earphones is often a serious problem when hearing levels are measured. This paper reports the acoustic calibration of clinical audiometers used for special periodic health examination. Methods: ANSI S3.6-1996 Specification for Audiometers represents our most current and best resource for information regarding audiometers. The acoustic calibration was measured in 211 clinical audiometers and compared with the ANSI S3.6-1996 reference threshold levels for supra-aural earphones. Results: Among 211 clinical audiometers, 56 (26.5%) exceeded the permitted deviation from reference threshold levels at any test frequency in ANSI S3.6-1996 for left supra-aural earphones, and 54 (25.6%) for right. An exhaustive calibration was required for 16 audiometers (7.6%) in both supra-aural earphones. The absolute difference in dB deviation from reference threshold levels by performed acoustic calibration at least annually were statistically significant at any test frequency (p<.05). Conclusions: The results of this study strongly indicate that clinical audiometry is being conducted with pure-tone audiometers having unallowable sound pressure levels deviations for supra-aural earphones. The validity of audiometric hearing thresholds are significantly affected by these deviations from the acoustic calibration levels of audiometers. Therefore audiometer calibration need to be checked functionally daily and acoustically at least annually.

This investigation provides experimental data regarding the flexural behavior and ductilities of reinforced high-strength lightweight concrete beams. The objectives of this study are (1)to study the flexural behavior of reinforced high-strength lightweight concrete beams and (2)to examine current ACI recommendations for flexural design in terms of strength and ductility. Test results show that the ratio of flexural strength between experimental results and those by ACI 318-95 is 1.01 in case of lightweight concrete. Also, When concrete compressive strength is 400kgf/cm<sup>2</sup> in reinforced high-strength lightweight concrete beams, the ratio of longitudinal reinforcement to balanced reinforcement needs to be limited to 0.5 in order to obtain 3 in ductility factor.

In current design, the strength formula for a Gusset-Tube connections stiffened with rib-plate is proposed only in the limited case because of its complexity of the behavior. So in this study, experimental study and finite element analysis were performed to investigate the behavior and strength of a Gusset-Tube connections stiffened with rib-plate. Because of limitations in loading capacity, the specimens were fabricated with 1/3 scale of full size. Tensile coupon tests and stub column tests were also carried out. Of primary interest here are the stiffened effect of Gusset-Tube connections considering lateral force ratio, gusset plate length, eccentricity, stiffened length. Consequently, we intend to obtain accumulated database to propose practical strength equation and suggest rational reinforcing method of Gusset-tube connection.

In seismic-resistant design of buildings of ductile frame, the possibility of formation of plastic hinge at column end demands sufficient member ductility. The paper summarizes results of an experimental study of reinforced concrete columns with high-strength materials and subjected to simulated seismic loadings. The experimental program consisted of 6, approximately one-third-scale, rectilinearly confined, high-strength reinforced concrete columns with concrete compressive strengths of approximately 700kgf/cm2. The primary variables of the testing program were the volumetric ratio, spacing, and configuration of transverse reinforcement. Experimental results indicate as follows : 1.There is no expectation of improved effectiveness of deformability by the types of transverse reinforcement when using high yielding strength transverse reinforcement. 2.When using high yielding strength transverse reinforcement, it is possible to widen the spacing that are designed based on seismic provision of ACI 318-89 and get an appropriate deformability as well. 3.The significant parameter to determine the deformability is the spacing of transverse reinforcement in the HSC columns.
