For modern business firms, the most important factor in determining comprtitiveness of a firm is technology, rather than capital. Technogical innovation is a driving force to develop an economy and is essential in growth and/or survival of a business firm. Following studies concerned with this subject, small business firms seem to be more efficient in technological innovation and developing new technology in several respects. Espercially in the new technology based industries, the small business firms have several advantages in technological innovation. In this study, we tried to show how to plan a technology development strategy in relation to management strategy when small business of theoretical and empirical study, we aimed to show the way to efficient management and procedure of technological innovation. For the research methodology, we firstly reviewed and analyzed current and previous studies about technological innovation strategy, efficient management, and selection of R&D projects. Secondly, the results of this theoretical study was examined empirically. The empirical study contains 153 questionaires and 30 interviews for business firms of this area. In addition, for the evaluation criteria for the selection of R&D projects, we sent questionaires to 60 professors who teaches R&D OR in university or college level. The result of these questionaires was analyzed and compared with that of the business firms of this area. The result of this empirical study shows that top management of small business firms should notice the importance of technological innovation and try to stimulate R&D activity. For the evaluation criteria for R&D projection, the criteria which could reduce the possibility of future uncertainty, maximize profit, and he suited for the situation of the business firm, should be established.

A wafer rolling etching system for the silicon bulk micromachining has been designed and fabricated. The silicon diaphragms were anisotropically etched in a 24.5 weight percent KOH solution. Compared to the conventional KOH etching systems, pyramidal hillocks, and wave-shaped structures on the etched surfaces were greatly reduced by using this system. After etching for time of 438 minutes, the average etched depth and the etch-rate were measured to be 537μm and 1.22μm/min, respectively. The average etching uniformity of etching depth was 0.87% in 5-inch wafer. Our results showed that the wafer rolling method enhanced etch uniformity and etch rate.

Pressure sore is an area of ischemic tissue loss resulting from prolonged or often repeated pressure, usually over a bony prominence of body. Recently, the prevalence of pressure sore is major clinical problem, due to the increased number of patients with spinal cord injuries or longterm comatous patient after traffic, industrial accidents. The surgical principles in the treatment of pressure sores are total excision of the ulcer, scartissue, bursae, complete removal of all infected bone with recontouring of bony prominences to alleviate discrete pressure points and resurfacing and padding of the defects with healthy and well vascularized tissues. The sacral sore is the most common site for the development of pressure sore in Korea. We had experienced 14 cases who had received surgical treatments for sacral sores with transverse lumbosacral back flap. We obtained the following conclusions. Advantages 1)It is quick and easy procedure 2)The flap elevation itself is relatively bloodless 3)The donor defect is in a non-weight-bearing area 4)Muscle is not sacrified(possibly of importance in the ambulatory patient) 5)Surgical options are preserved in cases of recurrence(the flap itself may be reelevated and inset in some cases of recurrence) Disadvantages 1)It is lacking the bulky padding afforded by alternative musculocutaneous flaps 2)The vascularity of the flap tip is empirically less dependable than that of a musculocutaneous flap 3)The donor defect is large, cannot usually be closed primarily, and may prove of cosmetic concern

Seasonal variation of biogeochemical characteristics was determined in Lake Shihwa from October 2002 to August 2003. When the lake was artificially constructed for the freshwater reservoir in 1988, the development of the strong haline density stratification resulted in two-layered system in water column and hypoxic/anoxic environment prevailed in the bottom layer due to oxidation of accumulated organic matters in the lake. Recently, seawater flux to the lake through the sluice has been increased to improve water quality in the lake since 2000, but seasonal stratification and hypoxic bottom layer of the lake still developed in the summer due to the nature of artificially enclosed lake system. As the lake is still receiving tremendous amount of organic matters and other pollutants from neighboring streams during the rainy summer season, limited seawater flux sluicing into the lake may not be enough for the physical and biogeochemical mass balance especially in the summer. The excess of accumulated organic matters in the bottom layer apparently exhausted dissolved oxygen and affected biogeochemical distributions and processes of organic and inorganic compounds in the stratified two-layered environment in the summer. During the summer, ammonia and dissolved organic carbon remarkably increased in the bottom layer due to the hypoxic/anoxic condition in the bottom layer. Phosphate also increased as the result of benthic flux from the bottom sediment. Meanwhile, dissolved organic carbon showed the highest value at the upstream area and decreased along the salinity gradient in the lake. In addition to the sources from the upstream, autochthonous origin of particulate organic carbon from algal bloom in the lake might be more important for sustaining aggravated water quality and development of deteriorated bottom environment in the summer. The removal of trace metals could be attributed to scavenging by strong insoluble metal-sulfide compounds in the hypoxic/anoxic bottom layer in the summer.

A Bicon Frise (7-month-old, intact female, B.W.: 3.5kg) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of the murmur which was picked up during routine vaccination. The grade 3 of continuous murmur was identified on the auscultation. In the thoracic radiography, descending aorta and main pulmonary artery were enlarged and vertebral cardiac scale (VHS) was 10. In the echocardiography, turbulent and continuous positive flow was identified in the pulmonary artery at the right parasternal short axis view. We found the patent ductus arteriosus (PDA) connected the main pulmonary artery with the aorta by CT image. So, the diagnosis of PDA was made. The continuous murmur was not identified on the auscultation after surgical correction was achieved by ligation of PDA.
