The role of Pseudomonas aeruginosa in human diseases has received increasing attention in recent years. There is considerable evidence that intestinal Gram negative bacillary infections are occuring with greater frequency. Among these bacilli, Ps. "aeruginosa is so notoriously resistant to many antibiotics that it occupies an almost unique position. 903 strains of Ps. aeruginosa were isolated from various clinical materials at Seoul National University Hospital during the period of January 1st, 1970 and December 31. 1974 and clinico-bacteriological studies were made. The results were summarized as follow. 1. Clinical materials, from which Ps. aeruginosa were isolated, were Pus 448, Urine 151, Sputum 142, Throat swab 34, Blood 33, Bile 20, Bronchial aspiration 10, Pleural fluid 8, Stool 8, Spinal fluid 4, Vaginal discharge 2, Bone irrigation 2 and Ascitic fluid 1, respectively. 2. The clinical departments and the percentage of strain numbers from various materials submitted from the departments: General surgery 30. 0%, Internal medicine 26. 1%, Urology 13.6%, Orthopedic surgery &4%, Chest surgery 6.5%, Pediatrics 4.2%, Neuro surgery 3.4%, Obstetrics and Gynecology 3.0%, E.N.T. 2.6% and other departments 2.2%, respectively. 3. The cases of mixed infection with Ps. aeruginosa in a clinical materials were 23.6%. 4. The bacterial species and number of strains isolated with Ps. aeruginosa were klebsiella aerogenes 61, Coagulase positive staphylococcus 51, Escherichia coli 35, a-hemolytic streptococcus 18, Alcaligenes faecalis 16, Coagulase negative staphylooccus 11, Proteus mirabilis 10, Paracolon bacilli 9, respectively. 5. The percentage of resistant straims of Ps. aeruginosa to various antibiotics were as follow: Gentamycin 6.6%, Colimycin 33. 1%, Streptomycin 7& 1%, Kanamycin 94.2%, Chloramphenicol 94.4 %, Oxytetracyclin 94.9%, Lincomycin 9&4%, Penicillin 99.9%, Ampicillin 99.9%, and Cloxacillin 100%.

In order to investigate the variation in the pattern of origin of the celiac and the cranial mesenteric arteries, forty-four specimens (guinea pig) anesthetized by ethyl ether were heparinized and exsanguinated. Neoprene latex solution was injected into common carotid artery of thirty-two specimens for gross dissection. Twelve specimens angiography were prepared by injecting fifty per cent of barium sulfate solution into exsanguinated animals and then radiographed on a soft X-ray apparatus (Shimadzu Waltes 60). 1. The celiac artery and the cranial mesenteric artery were observed to be arosed mostly from a common trunk of the abdominal aorta, the celiac-cranial mesenteric trunk(68.2%), but in three animals from thirty specimens an anastomotic branch was examined between the abdominal aorta and the celiac artery(6.8%). 2. The celiac artery and the cranial mesenteric artery were branched from separated origin of the abdominal aorta(31.8%), and an anastomotic branch was examined between the celiac artery and the celiac-cranial mesenteric trunk(6.8%) in three animals from thirty specimens. 3. the hepatic artery was arosed from three different origin such as celiac artery branched from celiac-cranial mesenteric trunk(45.4%), celiac-cranial mesenteric trunk(22.2%) and the celiac artery branched from the abdominal aorta(31.8%).

Stoichiometric mullite powder was prepared with Al(OH)₃, which was synthesized from Al₂(SO₄)₃·18H₂O and SiO₂, which was hydrolysised from TEOS(Al₂O₃:SiO₂=3 : 2 mole%), the sintered body of only mullite and the Y₂O₃ added mullite body were prepared and it's properties were detected. The results are follows. Crystalized mullite begins to founded from 1200 calaination and Well-Crystalzed mullite forms from the calcination temperature, 1300℃ . Crystal grains of mullite is accicular, and its relative density and bending strength of mullite ceramics which is sintered at 1650℃ are 92% and 180Mpa, respectively. As Y₂O₃ addtion the bending strength can be increased to 220MPa, because Y₂O₃ distribute and fill the vacancies of accicular mullite grain boundaries.

A study has been conducted for the coagulation characteristics of suspended solids made up of kaolin using Al-based inorganic polymeric coagulants; PACS(Poly Aluminium Chloride silicate) and PASS (Poly Aluminium Silicate Sulfate). PACS was found to be superior to PASS in its coagulating ability almost two times as much. The variation of ζ-potential of suspended particles in the sign and magnitude was closely related to the turbidity removed behavior. For the application of two coagulant mixtures, the overall coagulating power was a function of the mixing ratio and, in case of sequential dosage of two coagulants, the entire coagulation feature was governed by the firstly dosed coagulant. When a same amount of coagulant was dosed in partition to the supernatant water of one time treated wastewater, the final turbidity of two time treated supernatant water showed a lower value compared with the case that all amount of coagulant was dosed at one time. The size of coagulum formed using PACS was larger than that using PASS and it was thought that the coagulum size was determined by the coagulating power of coagulant. Slow mixing time and rate were considered to be influential on the degree of turbidity removal, but not on the ζ-potential of particles. An appropriate temperature range was established for a better turbidity removal and beyond this range the turbidity increased as the temperature rised.

Although fruit production and consumption have been increased by the improvement of national income and the changing of food request, those of processed fruits have been more increased. Nowadays, the importing amount of processed fruits is three of four times as much as exporting amount of processed fruits in the amount of quantity and money, and it is expected that the import of cheaper foreign-processed goods will be sharply increased by the set out of WTO(world trade organization) through UR conversation. Therefore, for domestic market, the competitive power should be developed by the curtailing the productive cost through the usage of unmarketable fruits and cheaper materials, prolongation and automation of packing factory, by the fruit quality improvement for consumer's taste, and by the governmental support such as facility fund. For foreign market, the exporting condition must be improved by the enlightenment of processed goods suitable for foreigner's taste and enlargement of importing countries.

PCB投與動物의 成長과 脂質代謝에 미치는 花紛粒의 影響

For the purpose of investigating the influence of pollen loads on growth and lipid metabolism in serum and tissues of PCB-administered rats, I treated some rats with different levels of PCB and others with additional pollen loads for 4 wks. Growth depression in PCB-administered rats was proportional to the PCB concentration, but was markedly improved by administrating pollen loads. Liver and kidney enlargement, hepatic fatty infiltration and hyperlipidemia in PCB-administered rats increased in proportion to the PCB concentration. However, pollen loads added to the PCB diet improved the toxicity symptoms by PCB. Furthermore, the symptoms by low PCB diet were completely disappeared by additional pollen load diets.

能率的인 人事管理를 爲한 行動科學的 考察

吳鍾錫 부산대학교 1970 論文集 Vol.11 No.1

Since an organization must be operated by and through people, the degree to which it is able to achieve its objectives is contingent upon how efficiently its personnel perform individually and collectively. Every manager, therefore, must be able to work effectively with people and to resolve satisfactorily the many and varied problems that the management of these people may entail. The activities of most enterprises today are becoming more and more complex in nature, so the managers in these enterprises are required to have greater technical competency than was formerly the case. In addition, they must have a better understanding of human behavior and of the processes by which personnel can be managed effectively. The present generation of employees tends to be more enlightened and better educated than were their predecessors. They demand more considerate treatment and a more sophisticated form of leadership, so we are not able to force people to work harder by threatening or by subjecting them to physical or verbal abuse. It means that we have to understand the reason why people behavior as they doand give proper motivations so that they can contribute to achieve the goals of organization. In this paper, I would like to study the "why" of human behavior first and then apply these disciplines to the effective management of people as followings ; 1. Changing circumstances of enterprise and personnel management. 2. Behavioral sciences to develop the ability. A. Many approaches to understand the "why" of human behavior B. Internal efficiency methods to provide the efficient people 1. Human needs-motivations 2. X Y theory 3. Conclusion
