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%.

학습조직전략의 재음미

1990년대에 들어오면서 학습조직에 관한 연구가 국내외적으로 활발히 전개되어 왔다. 그것은 기존의 경영혁신 노력들이 가졌던 한계를 극복하기 위한 노력의 일환이었다. 학습조직에 관한 연구는 조직개발에 관한 연구의 흐름속에서 그 발전을 보게 되었다. 조직개발연구는 두 가지 큰 연구흐름을 갖고 있었는데, 하나는 변화과정이론(change process theory)이고, 다른 하나는 실행이론(implementation theory)이다. 실행이론은 다시 네 가지 개입전략론으로 발전하였는데, 그 가운데 학습조직에 관한 연구는 조직변혁개입전략의 일환으로 연구된 것이다. 조직변혁(organization transformation. OT)연구는 바람직한 조직의 문화, 사명, 전략 등을 재규정함으로써 조직의 새로운 비전을 창출함에 그 초점을 두었다. 이러한 일련의 조직변혁개입전략 연구중의 하나가 학습조직(learning organization)전략이었다. 학습조직은 조직구성원들로 하여금 문제를 명백히 하도록 하고, 문제의 해결을 위한 지식을 창출케하고 공유케함으로써, 조직유효성을 증대케 하는 조직개입전략이다. 이러한 개입전략은 기존의 많은 경영혁신기법들이 가졌던 한계점을 극복하기 위해 연구된 전략이다. 즉, 기존의 경영혁신기법들은 특정 프로세스나 과업에 초점을 맞추었기 때문에, 경쟁에 필요한 유연한 사고와 적응력을 갖게 하지 못하였으며, 학습된 결과가 조직내의 다른 구성원들과 공유되지 못하고 다른 영역으로 응용되지 못하였다. 결국 조직전체의 유효성으로 연결되지 못한 결점을 갖고 있었다. 따라서, 본 연구에서는 학습조직전략이 조직의 경쟁력을 가져오는 새로운 전략으로서 인적자원의 개발에 바탕을 둔 전략이어야 함을 강조하고 있다. 그런 이유에서 인적자원개발을 위한 학습조직화를 강조하고 그러기 위한 학습조직구축전략에 초점을 맞추었다. 그리고 이러한 학습조직의 구축화에는 리-더의 역할이 결정적이라는 인식에서 리-더의 비전의 개발과 조직문화의 창조를 위한 리-더쉽의 중요성을 강조하였고, 두 번째는 정보나 지식의 공유와 활용, 그리고 그 정보나 지식을 공유하고 활용할 수 있는 조직구조의 변혁도 아울러 강조하였으며 끝으로 학습조직구축의 성공조건으로 학습조직에 기여한 구성원에 대한 평가와 그에 상응하는 보상 역시 구성원들의 동기부여에 필수적인 조건임을 강조하였다. 결론적으로 본 연구에서는 이러한 학습조직전략이야말로 21C의 새로운 변화적응전략으로서 재음미되어야 함을 강조하고 있다.

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.

Vascular endothelial cells release proteinase that degrade the extracellular matrix, thus enabling cell migration during angiogenesis and vasculogenesis. Endothelial cells secrete mainly the proform of matrix rnetalloproteinase-2. Matrix metalloproteinase-2 is Zn^2+ dependent protease produced by a variety of cell types. They have a fundamental role in tissue remodelling, tumour invasion and metastasis. The purpose of this study was to test if growth factors, such as angiopoietin-1, bFGF and VEGF can regulate the secretion of MMPs by endothelial cells. Of these growth factors, we found that VEGF is the strongest inducer of MMP-2 secretion. Both angiopoietin-1 and bFGF also induced the secretion of the MMP-2. VEGF induced MMP-2 secretion in a time- and dose-dependent manner. Pretreatment with phosphatidylinositol 3'-kinase inhibitors had no effect. NF-kB inhibitor, PDTC changed significantly the level of MMP-2 secretion from the cell. These results indicate that MMP-2 stimulates normal cell proliferation, wound healing and tissue remodelling in endothelial cells.

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.

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
