What Do We Know about Knowledge Management? Practical Implications for Software Engineering

There have been many claims about knowledge management's benefits in software engineering, such as decreased time and cost for development, increased quality, and better decision-making abilities. Although we can find some success stories illustrating these claims, particularly on aspects related to the systems and engineering schools, more research is necessary to explore the intersection between each school and the software engineering field. Researchers should continue to emphasize the need for a broad focus across multiple KM schools to suceed in improving KM's practical application in software engineering.     

Surgical treatment of the massively dilated ureter in children. Part II. Management by primary reconstruction

Bypass of the left ventricle was accomplished in dogs and the entire circulation was supported temporarily by only the right ventricle. The atrial septum was excised, and the atrium was repartitioned so that the pulmonary veins were in continuity with the right ventricle and the venae cavae were connected through the atrium. Anastomosis of the superior vena cava to the right pulmonary artery brought systemic venous return directly to the lungs. The main pulmonary artery was ligated proximal to the bifurcation, preserving distal confluence of right and left pulmonary arteries. A tubular prosthesis between the proximal pulmonary artery and the aorta connected the right ventricle to the systemic circuit. This procedure, or some modification of the principle, may have clinical feasibility in the treatment of patients with hypoplastic left heart syndrome.     

Acute effect of inorganic iodide after 131I therapy for hyperthyroidism

Patients treated with inorganic iodide weeks to years following 131I therapy for hyperthyroidism do not adapt to its antithyroid effect. To determine whether such adaptation occurs soon after 131I therapy, serum thyroxine (T4) and triiodothyronine (T3) concentrations were measured daily for 9-14 days following 131I therapy in seventeen hyperthyroid patients. Nine patients received 150 mg KI daily starting 48 h after 131I administration; eight received only 131I. Serum T4 and T3 concentrations did not change significantly in the patients who received only 131I. In the patients who received 131I and KI, serum T4 and T3 concentrations fell promptly, reaching nadir values 2-10 days after initiation of iodide, and then increased despite continuation of KI therapy. The mean maximal fall in serum T4 was 34% and in serum T3 42%. These results show that "escape" from the acute anti-thyroid effect of iodide occurs when it is given immediately after 131I therapy, thus limiting the utility of iodide as a therapeutic agent at this time.     

Spinocerebellar ataxia and HLA linkage: risk prediction by HLA typing

To determine the possibility of genetic linkage of spinocerebellar ataxia with the histocompatibility loci, we performed HLA typing and linkage analysis on 19 members of a kindred in which spinocerebellar ataxia was segregating in an autosomal dominant inheritance pattern. The ataxia locus was located on chromosome 6 at 12-cM distance from the HLA complex with lod score of 3.15 (odds is greater than 1400:1 favoring linkage over chance findings). Thus, the presence of the ataxia gene in members of this kindred at risk can be predicted with about 90 per cent accuracy by means of HLA typing in informative matings.
