Seung Uk Lee(李承郁) 한국경영사학회 2002 經營史學 Vol.28 No.-
Started from a small size Seung-Jik Park Shop, one of the oldest in Korean modern history of commerce, and grown with traditional Korean spirit of politeness and perseverance, Doosan Group today has become one of the largest groups of companies including such a gigantic company as Doosan Heavy Industries Co., Ltd. This study aims to explore the courses of growth and development of Doosan Group from historical and functional point of view and extract the characteristics of growth and the modes of behavior in order to define the growth factors. The method adopted for the study is based on the management history with particular focus on entrepreneurs involved. In 1896, the year classified in this study as embryo period of Doosan Group, ‘Maeheon’ Seung-Jik Park opened Seung-Jik Park Shop selling drapery. Then he established Kwang Jang Co, and Kong Ik Sa, a trading house, developed cosmetic product Parkabun and ventured into beer industry through the acquisition of Sohwa Kirin Beer. In this embryo period, the factor that enabled his companies to grow and develop was the management philosophy based on harmony, thrifty, honesty and trust that formed the company motto and enhanced the image of the companIes. The focus was rather on specialization of organizations for growth than diversification of activities for expansion. In the beginning his business was mainly on drapery with major focus on quality and reliability. By the time he ventured into such commodity business as cosmetics and beer, the quality of products be came the prime target to pursue and achieve. This period could be seen as initial stage of the group to accumulate the capital required for further growth. From the year 1951 when ‘Yonkang’ Doo-Byung Park began to lead the group, the formation period set in place. In such time of Rehabilitation followed by social chaos, Sohwa Kirin Beer was transformed into Oriental Brewery Co., Ltd. and Doosan Group began to be formed. This formation period marked the dawn of Doosan Group pioneering the beer market, launching construction and machinery industries and exploring the overseas markets. This period was the time when the need for the management to be separated from the capital was strongly felt in order to maximize the management philosophy carried forward from the initial stage of the Doosan Group. The growth factor from the management point of view was the corporate philosophy based on harmony, honesty and public service spirit. In 1974, a new era began with the appointment of management expert Soo-Chang Jung as Chairman and Chief Executive Officer. It was a major turning point for Doosan Group. The efforts of the top management in this period could be characterized by its focus on creation of growth paths for electronic industries, accumulation of technologies through strategic alliance or merging with the companies of advanced countries, and expansion or realignment of existing businesses. The first growth factor in this period was the emphasis of creativity that provided the basis and momentum for healthy management and the second was organizational restructuring to be prepared for acquisition and merging and maintain the specialty of each business unit. Take-off period started with the arrival of Chairman Yong-Kon Park in 1981 and continued until 1995. In this period, development of overseas markets was reinforced in the areas of beer. construction, electronics, glass, machinery and trading while new businesses were actively explored. The Group was pressing forward with continuous expansion, horizontally as well as vertically. The growth factors from the management point of view were customer-satisfaction, priority on Quality, innovation, recruitment of talented people as well as organizational change aimed for diversification and specialization through the new system and mixed use of business divisions and teams. The year 1996 saw the beginning of innovation period of Doosan Group, As the external e

Purpose: To compare corneal topographic changes using Orbscn II between keratoconus and keratoconus- suspected eyes. Methods: Thirty-seven keratoconus eyes, 17 keratoconus-suspected eyes and 37 normal eyes were evaluated by using Orbscan II corneal topography. We compared central phachymetry, anterior elevation from best-fit sphere (BFS), posterior elevation from BFS, most protruded corneal thickness, central corneal thickness, anterior chamber depth, corneal diameter, and pupil size. Results: Central pachymetry, anterior and posterior elevation from BFS, central corneal thickness, and anterior chamber depth were statistically significantly different between keratoconus and control eyes. Anterior elevation from BFS showed a significant difference between keratoconus-suspected and control eyes. There were statistically significant differences in central pachymetry, posterior elevation from BFS, central corneal thickness and most protruded corneal thickness between keratoconus and keratoconus-suspected eyes. Corneal diameter and pupil size showed no differences among the 3 groups. Conclusions: Suspected keratoconus eyes have a higher value of anterior elevation from BFS on Orbscan II topography as compared with control eyes. Central pachymetry, posterior elevation from BFS, central corneal thickness and most protruded corneal thickness may be helpful in distinguishing between keratoconus and keratoconus-suspected eyes.

Purpose: To evaluate clinical outcome of silicone tube intubation in lacrimal passage obstruction according to the lacrimal passage obstruction patterns by dacryoscintigraphy. Methods: Fifty-nine eyes of 52 patients complaining of epiphora were divided into three groups pre-sac (group 1), intra-sac (group 2), and intra-ductal (group 3) types by dacryoscintigraphy. We confirmed the obstructive sites of lacrimal passage by probing with Bowman probe, and excluded all the cases of not passing lacrimal pathway or without the obstruction of lacrimal pathway. In the silicone intubation, a tie between both silicone tube was made at silicone silastic sheet instead of Mersilk. Results: The success was defined as maintaining the patent lacrimal passage with irrigation and disappearing of epiphora for at least 3 months. The success rate of the silicone intubation was 16 eyes of 17 eyes (94.1%) in group 1, 19 eyes of 23 eyes (82.6%) in group 2, and 14 eyes in 19 eyes (73.7%) in the group 3. The highest success rate of silicone intubation was pre-sac type and the lowest success rate was intra-ductal type by dacryoscintigraphy. There is no significant difference of success rate among three groups. Conclusions: Although it`s required the longer follow-up period and larger subjects to evaluate the efficacy of silicone tube intubation, it should be useful management of silicone tube intubation, especially at the cases of pre-sac obstruction by dacryoscintigraphy.
