CNN's technologies that represent emotional detection include primitive CNN algorithms, deployment normalization, and drop-off. We present the methods and data of the three experiments in this paper. The training database and the test database are set up differently. The first experiment is to extract emotions using Batch Normalization, which complemented the shortcomings of distribution. The second experiment is to extract emotions using Dropout, which is used for rapid computation. The third experiment uses CNN using convolution and maxpooling. All three results show a low detection rate, To supplement these problems, We will develop a deep learning algorithm using feature extraction method specialized in image processing field.

Recently, the robustness against daily impact is important according to portablization and downsizing of mobile electronics. Especially, almost parts of cellular phone should undergo drop test when they fall 1.5 m above ground. This test simulates the case when cellular phone slips through user’s finger while he is talking on the phone. This paper studies a drop test of automatic focusing (AF) actuator for camera module in cellular phone. This component is composed of voice coil motor (VCM) as an actuator and leaf spring as a guide and suspension.

N/A Alcoholic liver cirrhosis is common in western society, but it is very rare in Korean. Its clinical features are similar to other types of liver cirrhosis. But it is caused by drinking alcohol. Alcoholic hepatitis usually precedes the alcoholic liver cirrhosis. We have seen 42year-old male patient who had drunk much for 24 years. His chief complaint was right upper abdominal discomfort. Percutaneous liver biopsy was performed, which showed typical picture of alcoholic liver cirrhosis. So we present this case with a review of literature.

Needle biopsy of the liver under direct vision of laparoscope if of proved value in the differential diagnosis of various hepatic lesions. But serious complication include uncontrollable hemorrhage from the biopsy site. On the other hand, newly introduced absorbable gelatin sponge, Gelfoam, have been used successfully for support as hemostasis in neurosurgery or vascular surgery. Therefore. The author tried to insert Gelfoam for support as hemostasis into the site of needle biopsy of the liver showing uncontrollable bleeding. For the purpose to evaluate above innovation, experimental and clinical studies were performed as following. In experimental study, needle biopsies of the liver were done on 24 rabbits, selecting the left posterior lobe as the biopsy site which was packed by Gelfoam, and the right anterior lobe as control site. Biopsy was done every 5 minutes interval on 4 rabbits, every 1 hour interval study on another 4 rabbits, and every 1 week interval on 16 rabbits till 4 weeks. As a clinical study, bleeding time, coagulation time, prothrombin time and bleeding time from the biopsy site after aspiration needle biopsy under the direct vision of laparoscope were measured in 6 cases of normal, 22 cases of hepatoma, 17 cases of liver cirrhosis, 10 cases of metastatic cancer, 9 cases of chronic active hepatitis, 2 cases of chronic persistent hepatitis, 2 cases of fatty liver and 1 case of acute viral hepatitis. In another 9 cases of various liver diseases who showed pulsatile or persistent bleeding over 10 minutes from the biopsy site, Gelfoam impaction at the biopsy site under direct vision of laparoscope was done and then measured bleeding time. The results were as follows. 1) In experimental study, tampon effect of Gelfoam was confirmed by collapse of hepatic cell cord around impacted Gelgoam in the biopsy site. 2) The bleeding time from the biopsy site had no direct relationship with the patient’s hemostatic data such as bleeding time, coagulation time and prothrombin time. And there was no significant difference in bleeding time from the biopsy site between normal group and various liver disease group. 3) Gelfoam packing into the biopsy site in 9 cases showing pulsatile or persistent bleeding more than 10 minutes controlled bleeding within 1 minute.

A clinical study was performed on 151 cases of diseases complicated by ascites who had been admitted to the department of Gastroenterology, Korea University Hospital from March 1975 to February 1978. The results were summarized as follow. 1. The total protein content of the ascites was highest in tuberculous peritonitis, ovary cancer, stomach cancer, hepatoma, liver cirrhosis and nephrotic syndrome in the descending order. The order was same in the specific gravity of the ascites and in the ascites/serum ratio of total protein. 2. The glucose concentration of the ascites was increased in liver cirrhosis and decreased in tuberculous peritonitis. 3. The chloride content of the ascites was elevated than blood level in all diseases except tuberculous peritonitis. 4. The lactic dehydrogenase (L.D.H) activity of the ascites was highest in ovary cancer, tuberculous peritcotis, stomach cancer, hepatoma, liver cirrhosis in the descending order. The ascites/serum ratio of LDH activity was highest in ovary cancer, stomach cancer, tuberculous peritonitis, hepatoma, and liver cirrhosis in the descending order. 5. Erythrocyte count of the ascites was significantly elevated in hepatoma and ovary cancer. In tuberculous peritonitis and stomach cancer, erythrocyte count was moderately elevated. Leukocyte count was significantly elevated in stomach cancer and tuberculous peritonitis. In all the diseases, lymphocyte composition was more than 55% and most prominant in tuberculous peritonitis.

The gastric diverticulums is a state of the localized protrusion of gastric wall. The gastric diverticulum is not common when compared with diverticulum in other sites of the gastrointestinal tract and it almost always occurs as a single lesion. It is hard to ascribe any clinical feature to this lesion, usually found incidentally and there are no physical findings of importance. There are few reports concerned with the gastric diverticulum in Korea. Recently authors experienced two cases of gastric diverticula in males and one case in female during upper gastrointestinal series and endoscopic examination. The musoca of which was pathologically normal. So we report those cases.
