        소프트웨어산업진흥법이 국내 IT 서비스 산업에 미치는 영향에 관한 실증적 사례연구

        홍성구,전삼현 한국IT정책경영학회 2018 한국IT정책경영학회 논문지 Vol.10 No.1

        In order to promote the rapidly evolving IT industry, Korean government has adopted a legal system through the Software Industry Promotion Law, but some questions are being raised on the actual IT industry. Some provisions, however, aim to promote SMEs by forcing them to restrict competition, but in reality, they provide dissatisfaction with both large and small businesses and public procurement organizations. Based on the results of the study, we propose that the improvement of the Software Industry Promotion Law will be improved by suggesting improvements in the Software Industry Promotion Law and the improvement measures for the actual IT industry development. 급변하는 IT 산업 발전의 진흥을 위해 국가에서는 소프트웨어산업진흥법을 통해 법적 장치를 마련해 두었으나, 실제 산업현장에서는 유효성에 대한 의문이 제기되고 있다. 또한 일부 법조항은 경쟁제한성을 강제함으로써 중소기업 육성을 도모하기도 하지만, 실제로는 대기업, 중소기업, 발주기관 모두에 불만족을 제공하고 있다. 이에 IT 서비스 기업의 실적과 사업 분야를 근거로 연구한 사례를 제시함으로써 소프트웨어산업진흥법의 개선 여부를 도출하고, 실제 IT 산업 발전을 위한 개선방안을 제시해 보고자 한다.

        논문(論文) : 『조선왕조실록(朝鮮王朝實錄)』에 비친 17세기 내륙아시아 정세와 "영고탑회귀설(寧古塔回歸說)"

        홍성구 중국사학회 2010 中國史硏究 Vol.69 No.-

        『朝鮮王朝實錄』包含了흔豊富的有關亞洲內陸史料. 然而, 對於這反映了즘樣的史實, 硏究不多. 雖然有的學者嘗試過這方面的硏究, 結論有所不同甚至完全相反. 本文旨在以17世紀亞洲內陸的情況爲硏究對象, 探究『朝鮮王朝實錄』反映的史實及朝鮮王朝支配階層的對外認識. 在後金出現以後的朝鮮, 對於蒙古的關心越來越多, 通過1636年設置的瀋陽館, 收集了更多的有關蒙古信息, 接近了淸朝和蒙古關係的實質. 但入關後, 有關淸朝和蒙古的衝突和對抗的新聞連續傳到朝鮮, 這引起了對於强盛的古蒙和對淸朝滅亡的期望和不安. 這是所謂``寧古塔回歸說``. 朝鮮收集的有關亞洲內陸的信息充分反映了足有這些期望和不安的史實, 隨著滿洲-漢-蒙古關係變化, ``寧古塔回歸說``所包含的這些期望和不安也變化從期望到不安, 從在實際的不安到觀念的姑息的不安. 所以可以說``寧古塔回歸說``反映了亞洲內陸政治力學的變化.

        풍건 목편을 이용한 합성가스 생산에 대한 실험적 고찰

        홍성구,왕용,Hong, Seong-Gu,Wang, Long 한국농공학회 2011 한국농공학회논문집 Vol.53 No.6

        Biomass gasification provides synthesis gas or syngas that can be used for internal combustion engines as fuel or chemical synthesis as feedstock. Among different types of gasifiers, downdraft gasifier can produce relatively clean syngas with lower tar contents. In this study, a downdraft gasifier was fabricated with 150 mm of hearth diameter to gasify woodchip that is commercially available in this country. After drying woodchip to about 20 %, gasification experiments were conducted measuring temperature, pressure, air and gas flow rates. The volumetric concentrations of CO, $H_2$, $CO_2$, $CH_4$ were 10.7~14.5, 16.5~21.4, 12.5~16.6, and 2.3~2.9, respectively. They were overall within the ranges of the results that the previous studies showed. However, CO concentration was relatively lower and H2 was slightly higher than those from other studies. It seemed that water gas shift reaction was occurred due to the moisture in the fuel woodchip. Additional drying process coupled with syngas cooling would be required to improve the overall efficiency and syngas quality.

        수리모형 실험에 의한 선박 부착형 오탁방지막의 거동특성 구명

        홍성구,강구,Hong, Seong Gu,Kang, Ku 한국농공학회 2012 한국농공학회논문집 Vol.54 No.6

        Silt curtains are constructed for minimizing pollution of sediment dispersion in water bodies. In spite of wide uses of the silt curtains, there are few studies for analyzing the effectiveness of them with respect to their dimension and hydraulic characteristics. Currently, the market of silt curtains does not provide the various dimension of them due to the limit of information regarding its effectiveness on reducing sediment pollution. In this study, a series of experiments were conducted to investigate hydraulic characteristics around the silt curtains under the different flow conditions. For this study, a silt curtain was fabricated and an open channel with 30cm of width and 40cm of depth was used. The results indicated that the silt curtain was not effective in preventing dispersion at flow velocities over 0.5m/s in real conditions. Based on the experimental results, it is required that approaching velocity should be minimized and the weight of bottom be increased in order to reduce deformation. The results of this study will provide information required to design appropriate dimension of silt curtains in various water environment such as velocity and water depths.

        한우의 방목개시월령과 비육기 조사료의 종류가 발육 및 육질에 미치는 영향

        홍성구,조원모,이종문,백봉현 한국축산학회 1997 한국축산학회지 Vol.39 No.4

        This study was conducted to investigate the effect of grazing starting age (6 and 9 months of age) at growing stage and roughages types at finishing stage on growth performance and beef quality in Hanwoo steers. Thirty nine steers were allocated to a control (T₁) and four treatment groups which were fed rice straw (T₂ and T₄) or grass hay (T₃ and T_5) ad libitum and water was provided continuously. Concentrates were fed at 1.8% level of live body weight during 15∼18 months and ad libitum from the 19th month. The results obtained were as follows: The daily gain of T₁ was lower (0.8㎏) than those of treatment steers (0.9㎏) and the amount of concentrate intake per ㎏ gain during 15∼24 months in T₁ was higher than those of treatments, also as dry matter basis obtained the same results, especially the treatments of T₃ and T_5 were lower (9.4 and 9.1㎏) than those of T₂ and T₄ (10.5㎏). The body weight gain of the 6 months groups was higher than that of the 9 month groups (p$lt;0.05). Looked at carcass characteristics, especially marbling score of T₂ and T₃ were higher(4.1 and 4.5) than those(3.5 to 3.8) of other treatments and beef yield also were higher. These results suggested that 6 month of grazing starting age would be recommended to increase growth performance, beef quality and quantity.

        경기 남부지역 풍력자원의 평가와 농업분야 활용방안

        Wind energy is one of the promising renewable energies that could provide electricity and other mechanical power. Wind energy market is dramatically growing in many European countries, but wind power is only 0.2% of the total renewable energy uses that is only about 2% of the primary energy consumption in Korea. It is widely accepted that wind resources fur power generation are only limited in some areas including coastal regions and mountainous areas in Gangwon province in Korea, particularly in terms of large scale wind power developments. In this study, wind velocity data were analyzed with respect to the potential utilization. The data provided from National Weather Service were used for the analysis. In addition, field wind data were also collected and analyzed for the comparison between the national data. The comparison showed that there were significant differences between the experimental station and the national station that are about 5km away. Annual average wind speed at the experimental station was less than 2 m/s, which is not enough fur wind power generation. It seemed that the topographic condition resulted in a significant difference in wind speed. When 600 W and 2.5 kW wind turbines were used, annual power productions were only 186 kWh and 598 kWh, respectively. When the average wind speed is lower, wind pumping is an alternative use of wind. At the experimental station, the average pumping rate of $3m^3/h$ at the head of 3 m was expected at a 2.5 m rotor under the conditions that efficiencies of the rotor and the pump were 40% and 80%, respectively. It did not seem that the wind pumping was not applicable at the station either. A higher wind speed was required to install the wind machines. Meanwhile, wind pumping would be applicable in conditions with lower pumping heads. Other applications were introduced far further wind energy utilization, including wind powered ventilation and friction heat generation in greenhouses.
