| 11 | Calculations of Forming Limit Diagrams for Changing Strain Paths on the Formability of Sheet Metal显示文摘In the press shop of most sheet metals, sheet material undergoes complex strain path and also the formability of the sheet material was limited by the stretchability of the material. Therefore, the precise prediction of path-dependent FLD based on M-K approach using generalization of Hill’s 1979 anisotropic yield criterion and introducing a strain gradient effect in the constitutive equation. Also, the theoretically obtained FLD will be compared with experimental data for steel sheets. | Hyunsung Sou Graduate School of Mechanical Eng., Kyungpook National University, Korea Youngsuk Kim Dept. of Mechanical Eng., Kyungpook National University, Korea | 2001 | Journal of Materials Science & Technology2001，17，1： | 1 |

| 15 | Appendiceal Crohn's disease clinically presenting as acute appendicitis显示文摘AIM: To determine the incidence of appendiceal Crohn's disease(CD) and to summarize the characteristic histologic features of appendiceal CD.METHODS: We reviewed the pathology files of 2179 appendectomy specimens from January 2007 to May2013. The computer-assisted retrieval search facility was utilized to collect specimens. We selected those cases that were diagnosed as CD or chronic granulomatous inflammation and defined the final diagnosis according to the histologic findings of CD, including transmural lymphocytic inflammation, non-caseating epithelioid granulomas, thickening of the appendiceal wall secondary to hypertrophy of muscularis mucosa,mucosal ulceration with crypt abscesses, mucosal fissures, and fistula formation. RESULTS: We found 12 cases(7 male and 5 female patients, with an average age of 29.8 years) of appendiceal CD. The incidence of appendiceal CD was 0.55%.The chief complaints were right lower quadrant pain,abdominal pain, lower abdominal pain, and diarrhea.The duration of symptom varied from 2 d to 5 mo.The histologic review revealed appendiceal wall thickening in 11 cases(92%), transmural inflammation in all cases(100%), lymphoid aggregates in all cases(100%), epithelioid granulomas in all cases(100%), mucosal ulceration in 11 cases(92%), crypt abscesses in 5 cases(42%), perforation in 2 cases(17%), muscular hypertrophy in 1 case(8%), neural hyperplasia in 5 cases(42%), and perpendicular serosal fibrosis in 8 cases(67%).CONCLUSION: A typical and protracted clinical course, unusual gross features of the appendix and the characteristic histologic features are a clue in the diagnosis of appendiceal CD. | Hulin Han Hyunsung Kim Abdul Rehman Se Min Jang Seung Sam Paik | 2014 | World Journal of Clinical Cases2014，2，12： | 1 |
| 16 | Cytomegalovirus enteritis with jejunal perforation in a patient with endometrial adenocarcinoma显示文摘Cytomegalovirus(CMV) infection of the gastrointestinal tract has been reported most frequently in the setting of immunodeficiency. The whole gastrointestinal tract can be affected; however, the small bowel is rarely affected. We report a case of CMV enteritis with jejunal perforation in a 53-year-old woman with a history of chemoradiation therapy for endometrial cancer 8 years previously. At follow-up evaluation, lower abdominal pain, diarrhea and vomiting appeared. Abdominal computed tomography showed intra-abdominal free air in the subphrenic space and porta hepatis. The jejunal segment revealed serosal purulent exudates with a perforation. The resected jejunal segment showed a large geographic ulcerative mucosal lesion. The microscopic findings revealed a diffuse ulcerative mucosal change with a prominent granulation tissue formation and many large atypical vascular endothelial cells and stromal fibroblasts with intranuclear or intracytoplasmic inclusion bodies. These cells were positive for CMV antibody. The final diagnosis was CMV-associated jejunitis with a jejunal perforation. | Young Jin Jun Jongmin Sim Hye In Ahn Hulin Han Hyunsung Kim Kijong Yi Abdul Rehman Se Min Jang Kiseok Jang Seung Sam Paik | 2013 | World Journal of Clinical Cases2013，1，7： | 0 |
| 17 | Feasible Resolution of Angular Displacement Measurement by an Optical Angle Sensor Based on Laser Autocollimation显示文摘The feasible resolution of angular displacement measurement by an optical angle sensor based on laser autocollimation is investigated.Improving the sensor sensitivity while maintaining the noise level of the sensor signal as low as possible is necessary to achieve high-resolution angular displacement measurement.In this paper,the contribution of each component,such as a photodiode,a trans-impedance amplifer,and an analog-to-digital converter in the optical angle sensor,to the noise level of the sensor signal is frst estimated on the basis of theoretical equations.The feasible sensitivity of the optical angle sensor is also estimated in numerical calculations.The sensitivity of a photodiode element at the edge of its photosensitive area is evaluated in experiments to realize the estimation of the angle sensor sensitivity.Experimental results are applied to the numerical calculations.The infuences of the measurement laser beam diameter,the spot diameter of the focused laser beam on the photosensitive area,and the focal length of the collimator objective of the optical angle sensor are also consid-ered in the numerical calculations.Finally,a prototype optical setup is developed.Experiments are performed to demonstrate that a compact optical angle sensor based on laser autocollimation with a collimator objective having a focal length shorter than 100 mm can achieve a resolution beyond 0.001 arc-second with a bandwidth of 1 kHz.This resolution is better than those achieved by commercial autocollimators employing an image sensor or a position-sensitive detector.The industrial contribution of this paper lies in the detailed breakdown of noise components in the readout signal of an angle sensor in a practical condition and the systematic estimation of its feasible resolution as well as its sensitivity. | Hyunsung Lim Yuki Shimizu | 2023 | Nanomanufacturing and Metrology2023，6，4： | 0 |
