Between 1979 and 1991 thymectomy was performed on 31 patients with myasthenia gravis at the department of thoracic and cardiovascular surgery, Keimyung University medical school. All patients were treated by transsternal thymectomy. During follow-up period that ranged from a month to 10.7 years[mean 2 years], the remission rate for the entire group was 16.1 percent and an additional 71.0 percent had improvement [87.1 percent benefited]. In those 8 patients with thymoma, the remission rate was 12.5 percent with 75.0 percent of the patients benefiting from operations The remainimg 23 patients fared better the operations: 17.4 percent had remission and a total of 91.4 percent benefited. There was no mortality, I concluded that most patients with myasthenia gravis will benefit from thymectomy, and that the improvement persists over an extended period of time in a high percentage of patients.

The study was conducted to determine the nutiritional value of Masoor (Lens esculenta) in raw and cooked forms. Supplement value of various types of meat i.e. poultry, mutton and beef at 10, 15, and 20 percent levels for dite containing cooked Masoor was also assessed. Nutritional value of Masoor was determined by chemical analysis as well as through rat assay. Masoor contained an average of 23.18 percent protein and less than two percent fibre. Conventional method of cooking resulted in about 2 per cent increase in Masoor protein. Masoor had 0.83 percent of lysine and cooking destroyed 18 percent of it. Other amino acids in Masoor also showed losses on cooking. Protein efficiency ratio (PER) of diets containing raw Masoor was 1.49 and was reduced to 1.44 by cooking. Cooking of Masoor did not alter true digestibility (TD) percentage. However, net protein utilization (NPU) was improved from 44.60 in raw to 47.77 in cooked. Diets containing cooked Masoor and supplemented with different types of meat significantly improved PER (1.45 to 1.65), TD 76.03 to 87.84 percent and NPU 42.84 to 50.72 percent over non supplemented diets. 20 percent level of supplemented meat showed comparatively better results than other levels in case of improvement in PER, TD and NPU.

Background : This study was carried out to assess the quality improvement(QI)activities in Korean hospitals. Methods : A mailed questionnaire survey was conducted between September 15 and October 30, 2000. The staffs being charge of QI each of the hospitals with 400 beds or more responded to the questionnaire. Of the 108 hospitals eligible for inclusion in our study, 69 participated, yielding a response rate of 63.9%. Results : Based on these survey, 87.3 percent of the responding hospitals were performing QI projects and 54 percent of the hospitals had a separate department for QI activity. About 62 percent of hospitals performing QI activity (QI hospitals) had a QI manager and 58 percent had a separate budget for QI activities. Among the QI hospitals, 85 percent had cross-functional or cross-departmental teams as the major mechanisms for doing QI projects, 94 percent had one or more educational programs on QI. The level of physician's participation level for QI projects was lower than other staff(CEO, nurses and other administrators). Conclusion : The majority of the hospitals have undertaken activities in QI. For the successful implemented QI, the involvement of and education for employees(including physicians and other health professionals)are needed as well as management strategy and leadership. Understanding of other hospitals experience would be helpful for health care managers to plan and initiate QI activities.

A study was conducted on 2102 records of 808 crossbred cows of various genetic groups maintained under 'All India Coordinated Research Project on Cattle' at C C S Haryana Agricultural University, Hisar, over 25 years period (1968-1993) with an objective to assess and compare the amount of percent improvement and heterotic effect for different performance traits in various genetic groups produced under this programme. Survivability sharply and significantly declined from 1/2 to $3/4^th$ bred and further from $3/4^th$ to inter-se bred. This may be due to periodic and management differences in addition to the higher level of exotic inheritance and decreased heterotic effect over the filial generations. Jersey and Holstein Friesian crosses among 1/2 breds and their 50% inheritance among $3/4^th$ and inter-se breds had highest improvement and heterosis in reproduction and production traits respectively. Among inter se bred genetic groups, BFH (I) had no recombination loss in SP and CI, while FJH (I), JFH (I) and FBH (I) had on recombination loss in AFC, LY, LL and PE. The crossbreeding of zebu cows with exotic breeds brings about spectacular improvement in comparison to the performance of zebu breed, while conventional selection over several generation would lead to only modest improvement. In addition to additive effect, there was sufficient heterosis in Jersey crosses for reproduction and Holstein Friesian crosses for production performance. Three breed crosses with exotic inheritance between 50 and 75 percent incorporating genes (25 to 50%) from both of these breeds is the best combination for stabilization.

Also, SSF means that farmer brings about management innovation through improvements of continuous competence and individual efforts. Ultimate goals of SSF are to improve competence of farm household by 20 percent and to increase farm household income by 10 percent. The purpose of this paper is to examine the factors affecting the improvement of competence of the Strong Small Farm. The major findings of this study are summarized as follows. First, the results indicated that competence of farm household was improved by 8.5 percent. Second, the findings showed that management plan report, implement report, precision management consulting and whether or not he or she was urban to rural returner had a significant impact on improvement of competence.

Myasthenia gravis is an autoimmune disease in which the thymus gland is thought to play a central role in the pathogenesis. Thymectomy is now standard therapy, and improvements in surgical techniques, anesthesia, and respiratory care and the use of plasmapheresis have markedly reduced the operative morbidity. We experienced 7 myasthenia gravis with maximal thymectomy from November 1989. As compared with the results of previous classic transsternal thymectomy group the 25 patients who were operated from June 1979 to December 1991[Group B], excellent surgical result was obtained in maximal thymectomy group[Group A]. During follow-up period that ranged from a month to 10.7 years[mean 2 years], the remission rate for the entire group was 15.6 percent and an additional 71.9 percent had improvement[87.5 percent benefited]. In Group A, the remission rate was 42.9 percent with 100 percent of the patients benefiting from operations. But in Group B, 8 percent had remission and a total of 80 percent benefited. In both Groups, there was no operative mortality but there was one case`s mortality in Group B during follow-up period.

One of the most pressing problems of the day in our household economy is the scientific improvement of meal management, which has direct bearings on the efficiency of housewives, domestic economy, and health care for the whole family. The concern of this paper is to investigate the current meal management situation in which more than three hundred housewives in Seoul find themselves, and to propose a tentative plan for its improvement. The result of the investigation is summarized as follows : 1) The number of families with old-fashioned kitchens forms a percentage of 30.3 ; only 4.3 percent of them have waterworks and drainage system. 2) The number of families equipped with cooking machines and utensils constitutes 51.2 percent ; that of those without cooking machines reaches the high percentage of 92.8. 3) The expense for daily meals amounts to 37.9 percent of the whole domestic expenses. the number of those who prepare daily meals without any planning comprises 78 percent. It is from habit that 60.5 percent of them make no workable plan for their meals. 4) The frequency of housewives doing daily marketing is comparatively high. 5) The time spent in preparing and clearing the table is 280.4 minutes a day on the average. 6) In preparing daily meals the low income bracket tends to keep expense as low as possible, while the high income bracket is chiefly concerned with taste. 7) The frequency of home cooking is on the increase as the housewives grow older, especially in the large families with housemaids. 8) In most cases housewives do the cooking for themselves; the high income brackets have housemaids do the cooking. The number of husbands who help their wives do kitchen work a small percentage of 10-14. 9) The simplification of kitchen work presupposes the simplification of the daily cooking, the improvement of the structure and equipment of the kitchen, and a good help of the whole family.

1. In order to make the improvement of plywood quality, this study has been made. The pretreatments applied to the veneers are as follows. a) The soaking treatment of the veneer in 30 percent methanol solution for 24 hours was applied to remove some resinous materials which may cause many stain discolouring on the face of finished plywood. b) The preservative treatment of the veneer in 2 percent malenit solution for 2 to 3 minutes was adopted to make resistance against decay and insect damages. c) The fire retardant treatment of the veneer in 40 percent ammonium phosphate solution for 2 hours was applied to give retardation effect against fire burning. 2. The results summarized in this study are as follows. a) One percent resinous materials was extracted, after the soaking of the veneers in 30 percent diluted methanol. b) No marks of the dirty stains of resinous materials on the face of the treated plywood was shown, although many quite dirty stains on the face of untreated plywood have contrary seen. c) However, the strip shear test strength of the treated plywood was not decreased. It means that there is no difference in the strength between the treated plywood and the untreated plywood. The strength values were 25.08 kg/$cm^2$ and 24.98 kg/$cm^2$, respectively. d) The strip shear test strength of plywood made of the treated veneers in 2 percent malenit solution was not decreased. e) The slight decrease of the strip shear test strength of the treated plywood made of the treated veneer in 40 percent ammonuim phosphate solution was shown. However, the remarkable difference of the fire retardation activities between the treated specimens and the untreated specimens has seen as in Table 10, that is, the fire proofed specimens had taken about 28 seconds to start to burn, while the untreated specimens had taken 15 seconds to reach to burning. This means that the fire retardation effect of the fire proofed plywood was greater than that of the unproofed plywood.

The integrated soil improvement practice reduced neck blast incidence by ranging from 6.3 to 59.5 percent compared to control plot. However, effect of integrated soil improvement practice in reducing neck blast incidence was greater in Tongil type cultivars. On the contrary, mean value of plant height of eleven rice cultivars was taller by 6.4cm in the integrated soil improvement plot with 2.3 more tillers than that of control plot. As a result, yield increase of milled rice by metric tons per hectare was 24.1 percent in the integrated soil improvement plot.
