Lung cancer is one of the most disastrous of all the current cancers in Korea. In 1990 it was projected that there would be 5, 500 new lung cancer patients in Korea and that 5, 000 would die of their disease. This is a mortality rate of 91 percent. We reviewed the surgically treated 153 bronchogenic cancer patients from January 1987 to December 1991 in St. Mary`s Hospital of Catholic University Medical College. There were 121 men and 32 women ranging in age from 18 to 83 years, with a mean of 56 years. Of the 153 patients, resection was possible in 138 patients and the resectability was 90.1 percent. Squamous cell carcinoma was present in 48 percent of patients, adenocarcinoma in 29 percent, adenosquamous carcinoma in 7 percent, large cell carcinoma in 6 percent, salivary gland tumor in 5 percent, and small cell carcinoma and carcinoid in 3 percent respectively. Postoperative cancer staging was grouped stage I 33 percent, stage II 21 percent, stage IIIa 35 percent, and stage IIIb 10 percent. Lobectomy was performed in 70 percent, pneumonectomy in 17 percent, and segmentectomy in 14 percent. Three and 5-year postoperative survival in resectable 138 patients were 47 and 29 percent respectively.

To improve the nutritive value of wheat straw it as treated with 0, 3, 4 and 5 percent levels of urea, 0 and 4 percent level of alkali at 40, 50 and 60 percent moisture levels and stored at room temperature. Total nitrogen contents of the straw increased significantly, from 0.77 percent with no urea treatment to 0.87, 1.16 and 1.19 percent with 3, 4 and 5 percent urea levels, respectively. Percent retention of nitrogen was 63.73 percent. Alkali treatment at 4 percent level, lowered significantly the crude fibre contents of the straw from 41.86 percent in control to 40.21 percent in the treated straw. Moisture level of 40 percent significantly lowered (p < 0.05) the crude fibre contents. Total ash content of straw increased significantly by urea and alkali treatment. Alkali treatment improved significantly the sodium contents also. The results of the study indicated that most beneficial results were obtained with 4 percent urea, 4 percent alkali at 50 percent moisture level.

As an attempt to reduce the consumption of petroleum resources and to improve the performance of a kerosene engine, a series of experiments was conducted using several kinds of ethanol-kerosene blends under the various compression ratios. The engine used in this study was a single-cylinder, four-cycle kerosene engine having a compression ratio of 4.5. To investigate the feasibility of ethanol-kerosene blends in the original engine, kerosene and blends of 5-percent, 10-percent, and 20-percent-ethanol, by volume, with kerosene were used. And to investigate the feasibility of improving the performance of the kerosene engine, a portion of the cylinder head was cut off to increase the compression ratio up to 5.0 by reducing the combustion chamber volume. Kerosene and blends of 30-percent and 40-percent-ethanol, by volume, with kerosene were used for the modified engine with an increased compression ratio. Variable speed tests at wide-open throttle were also conducted at five speed levels in the range of 1000 to 2200 rpm for each compression ratio and fuel type. Volumetric efficiency, engine torque, and brake specific fuel consumption were determined, and brake thermal efficiency based on the lower heating values of kerosene and ethanol was calculated. The results obtained in the study are summarized as follows: A. Test with the original engine: (1) No abnormal conditions were found when burning ethanol-kerosene blends in the original engine. (2) Volumetric efficiency increased with ethanol concentration in blends. When burning blends of 5-percent, 10-percent, and 20-percent ethanol, by volume, with kerosene, average volumetric efficiency increased 1.6 percent, 2.6 percent, and 4.1 percent respectively, than when burning kerosene. (3) Mean engine torque increased 5.2 percent for 5-percent-ethanol blend, 9.3 percent for 10-percent-ethanol blend, and 11.5 percent for 20-percent-ethanol blend than for kerosene. Increase in engine torque when using ethanol-kerosene blends was due to the improved combustion characteristics of ethanol as well as an increase in volumetric efficiency. (4) Up to ethanol concentration of 20 percent, mean brake specific fuel consumption was nearly constant inspite of the difference in heating value between ethanol and kerosene. (5) Brake thermal efficiency increased 0.3 percent for 5-percent-ethanol blend, 3.8 percent for 10-percent-ethanol blend, and 6.8 percent for 20-percent-ethanol blend than for kerosene. B. Test with the modified engine with an increased compression ratio: (1) When burning kerosene, mean volumetric efficiency, engine torque, and brake thermal efficiency were somewhat lower than for the original engine. (2) Engine torque increased 15.1 percent for 30-percent-ethanol blend and 18.4 percent for 40-percent-ethanol blend than for kerosene. (3) There was no significant difference in brake specific fuel consumption regardless of ethanol concentration in blends. (4) Brake thermal efficiency increased 15.0 percent for 30-percent-ethanol blend and 19. 5 percent for 40-percent-ethanol blend than for kerosene.

In order to evaluate the effect of lipids on the utilization of the energy and protein of the diet, the isocaloric and isoprotein diets added with mutton fat, tallow, and lecithin at the levels of two percent and five percent were prepared. The growth of chicken and the feed efficiency were observed on hatched chicken which were fed a commercial diet for the first week, with starters for the next four weeks, and with finisher diets for the last three weeks respectively during the eight weeks of the experiment. Growth rate, feed efficiency, and average body weight gain per day were similar among the chicken fed diets containing various lipids or at the levels of two percent and five percent. The metabolize energy of the diets was found to be from 2.713 kcal to 3.059 kcal per gram, and the metabolizability of the gross energy was from 62 percent to 70 percent. Also the metabolizability of basal diet was higher as compared with the diets containing lipids. And the lower energy utiliztion was found in the broilers fed diets containing five percent lipids than those of two percent, showing not significant difference between them. Daily matabolizable energy of three week old brids ranged from 0.631 gr to 0.738 gr, which showed an increasing tendency on the birds fed five percent mutton fat and tallow in comparison with those of two percent. But the lecithin brought about a reverse tendency. The digestibility of crude fats was found to be from 48 percent to 76 percent, but bot significant difference among diets plus lipids or at the levels of two percent and five percent. The birds fed five percent mutton fat and tallow showed a tendency of lower digestibility as compared with those fed two percent, but the similar results were found between two percent and five percent lecithin fed to the birds. Then, it was tentatively concluded that the effect of the mutton fat on the energy and protein utilization was similar to tallow but resulted different tendency with lecithin.

Among 60 children with teratoma, forty-three (71.7 percent) were girls and 17 (28.3 percent) boys, Primary sites were sacrococcygeal in 30 patients (50 percent), retroperitoneal in 12 (20 percent), ovarian in 11 (18.3 percent), testicular in 3 (5 percent), and one in each of nasopharyngeal, gastric, hepatic and pancreatic (1.6 percent, respectively). Fifty-five (91.7 percent) teratomas were benign and 5 (8.3 percent) malignant. Malignant teratomas W8,re detected only in the sacrococcygeal region (16.7 percent). Age greater than 2 mouths at diagnosis, presence of urinary or colonic obstructive symptoms, multiple masses and elevated serum alpha-fetoprotein were indicators of malignancy in the sacrococcygeal region. Tumor size, presence of calcification, and gross apperance (cystic or solid) did not correlate with malignancy. Thirteen (21.7 percent) cases were associated with other anomalies. For the immature teratoma, operative resection without adjuvant chemotherapy was adequate treatment. Three patients with malignant tumors survived, one who received chemotherapy survived 3 years and the others without chemotherapy survived for 5 and 10 years.

As the result of a survey conducted by the author on the status of tile 12 educational institutions for mentally retarded children in Korea and their quartering facilities as well as on 934 children accommodated in such institutions, the following conclusion has been reached: 1) More than a half (approximately 58 percent) of the facilities for mentally retarded children are concentrated in Seoul. About eighty-three percent of these facilities are private establishments, of which 70 percent have their proprietors concurrently as their superintendents. Although these facilities were first established as many as 22 years ago, it has been only five or six years since education was actually started for mentally restarted children. 2) Out of a total of 179 employes, teachers number 99, there by constituting approximately 57.6 percent. Out of them, however, only 32 teachers or 2.8 percent have special teachers licenses. Thus, each teachers has to take care of an average of 29 children. This is excessive a number of children per teachers in view of the special nature of this education, there by indication how urgent it would be to secure more teachers lot this field. 3) Out of the mantally retarded children investigated 57.6 percent suffer from physical disorder in addition to mental retardation, 53.0 percent from mental alienation illnesses besides retardation, and 25 pent from physical, mental disorders in addition to retardation. It is therefore necessary to maintain medical and nursing facilities together with educational facilities. however, two places have no medical facilities at all, and four other places, without medical personnel, have to receive medical support from nearby hospitals or clinics. 4) The total number of children in the surveyed facilities is 934, who can be broken down into 58.7 percent boys and 41.3 percent for girls. They are classified into 12.5 percent for idiot, 37.7 percent for imbeciles, 32.7 percent for morons, and 17.3 percent for thoes children on borderline. Their average age is 13.9 years. 5) As the result of education, the illiteracy rate of mentally retarded children has decreased from 78.1 percent to 32.1 percent while the percentage of those taking the primary school course has increased for 12.2 per cent to 33.5 percent. As a result, it has been learned that education is definitely necessary for Retarded children though it may be a difficult task. 6) The children who have mentally retarded children among their brothers or sisters constitute 6.3 percent of the total number. The corresponding rate for boys is 3.5 percent while that for girls is a remarkably higher rate 10.6 percent. Through studies on the causes of their mental retardation, it has been learned that 39.6 percent of them is of the inherent type and 35.3 percent is of the environmental type. Control and improvement of health of mothers and children, early diagnosis and early treatment are believed to be very important because they could prevent or alleviant much of these conditions. 7) The storage age of teachers and employes is 35.3 years, an indication that a great proportion of them is experienced in a way or another as their major difficulty or problems in serving with these special school, 22.5 percent cited inadequate payment 24.5 gave the inadequate public understanding, and 22.5 percent pointed out the lack of understanding on the part of give parents.
