현대 건설 산업의 경쟁적인 사업 환경으로 인해 건설기업의 도산 가능성은 더욱 높아졌다. 이에 따라 성장위주의 경영에서 가치 중시 또는 수익 중심의 질적인 경영 환경으로의 전환이 요구된다. 현재 건설기업의 자본 조달은 대부분 금융기관을 통해 이루어지고 있다. 기업 규모의 성장에 따라 증권시장을 통한 자금조달의 형식을 갖추고 있지만, 기업 공개를 통한 정당한 수익성 배분이 이루어지지 못하고 있다. 특히 건설기업들은 기업 투명성에 대한 의식의 결여로 투자자들의 신뢰를 잃었고, 그로 인해 다시 주식시장을 통한 자금 조달에 실효성을 갖지 못하는 악순환이 계속되고 있다. 본 연구에서는 건설기업의 경영실태 파악을 위해 주식가격과 기업의 재무적 요인간의 상관성을 분석하였다. 이를 통해 상장건설기업의 주식가격과 기업경영성과 사이의 상관관계를 알아보고자 하였다. 또한 증권시장을 통한 기업 필요자본 조달의 필요성에 대하여 언급하고자 하였다. The bankruptcy possibility of construction firms have been higher by the environment of current construction industry. Thus, converting management environment for growth into that for value or profit is required. Nowadays, funds of construction firms is almost provided by financial institutions. As the firms' size grow, they have a form of fund provision through the securities market; however, fair distribution for returns is not practiced by opening company. Especially, construction firms lost trust of Investor by lack of awareness to firm clearness, and then a vicious cycle of no effectiveness in fund provision through securities market is continued again. On this study correlation between stock quotations and primary financial factors of firms in order to grasp actual management condition in construction firms was analyzed. By this, the correlation between stock quotations and the result of firm management was provided. Also, necessity of firm's capital provision was explained, thus ways to ensure firm clearness was searched.

Purpose : The object of this study was to observe the suppressive effects of Yijintang-gamibang (YJGMB), Yijintang with Atractylodis Rhizoma, Massa Medicata Fermentata, Hordei Fructus Germiniatus, and Coptidis Rhizoma. YJGMB has been traditionally used in Korean medicine for treating various digestive diseases. We tested it on the rat reflux esophagitis (RE) induced by pylorus and forestomach ligation in rats as compared with omeprazole, a well-known proton pump inhibitor. Method : Three different dosages of YJGMB 200, 100 and 50mg/kg, were orally pretreated once a day for 28 days before pylorus and forestomach ligation. Seven groups, each of 8 rats per group were used in the study. Six hours after pylorus and forestomach ligation, changes of the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, invasive lesion percentages, fundic mucosa and total thicknesses were measured as histomorphometry. The results were compared with omeprazole, antioxidant and proton pump inhibitor, and 30 and 10mg/kg treated groups in which the effects on RE were already confirmed. Results : As results of pylorus and forestomach ligation, marked increases of esophageal and gastric mucosa lesion areas, gastric volumes, acid outputs, pepsin outputs were observed with histopathological changes of RE, such as hemorrhages, ulcerative lesions and edematous changes on the fundic mucosa. However, these pylorus and forestomach ligation-induced RE were dose-dependently inhibited by treatment of 200, 100 and 50mg/kg of YJGMB. YJGMB 200mg/kg showed similar protective effects as compared with 30mg/kg of omeprazole in the present study, and more favorable effects were observed in 50mg/kg of YJGMB treated rats as compared with omeprazole 10mg/kg in the present study. Conclusion : The results obtained in this study suggest that YJGMB has favorable protective effects on the RE induced by pylorus and forestomach ligation. Therefore, it is expected that YJGMB will also show favorable effects on RE corresponding well to the suggestion of traditional Korean medicine. However, more detailed mechanism studies should be conducted in future with the screening of the biological active chemical compounds in herbs.

본 논문에서는 스위칭 레귤레이터의 한 형태인 승강압형 DC-DC 콘버어터에 있어서 전달함수의 우반면에 존재하는 영점이 안정성에 대하여 미치는 영향을 고찰하였고, 출력전류의 변화에 대한 안정범위를 궤한이득을 통하여 구하였다. 이 결과로부터, 우반면에 영점이 존재하기 때문에 안정성이 저하됨을 알 수 있었다. 궤한제어회로에 극 보상을 하였고, 이경우 유효한 안정성의 범위를 이득대역폭적과 관련지어 구하였으며 실험을 통하여 이를 입증하였다. This paper investigated the effect of the zero on the right-half-plane on stability in the buck-boost DC-DC converter which is one type of the switching regulator, and the stability region in connection with the output current was shown by evaluating the feed-back gain. From the result it is shown that the stability decreases by the existence of the zero on the right-half-plane. We carried out a compensation by a pole in the feedback circuit and obtained the available stability region in relation to the gain band-width product. These results proved to be the validity by experiment.

Synthetic organic polyelectrolytes can be used to condition sludges to enhance their dewaterability. Intermittent aerobic digestion is an useful digestion technology and has many advantages like neutral pH, low installation cost and easiness to operation. The objectives of this study were to investigate the dewaterability of intemittent aerobic digestion sludge and to find the relationship between dewaterability and particle size distribution change under the conditioning of intermittent aerobic digestion sludge by cationic polyelectrolyte. Digested sludge from intermittent aerobic digestion was used and cationic polyacrylamide polymer was added as a conditioner. CST(capillary suction time), TTF(time-to-filtration) were tested as a dewaterability index and the number of particle distribution was analyzed using particle size analyzer. The results indicate that cationic polyelectrolytes is useful to enhance dewaterability of intermittent aerobic digestion sludge. Mean particle diameter was increased as polymer dosage increased and its value was reached up to 100 mm on the condition of optimal cationic polymer dosage. CST and TTF are well correlated with mean particle diameter when the weighting order is 1.7. By the optimal conditioning with cationic polymer, particles in the filtrate are also reduced significantly and this means that conditioning is helpful to main stream by reducing SS loading from return flow.

This study is aimed at suggesting information about technical choices for designing LED camping lights based on emotional lighting contents of integrated IOT and design areas which take a central role in creation and knowledge based industries and the procedure for materializing them. ‘i-Light,’ a portable LED camping light, is ‘connected lighting’ connecting men, space and emotion and a smart camping light based on IOT and emotional lighting contents. ‘i-Light’ has two functions. One is about lighting for adjusting color and color temperature naturally and the other is about safety for detecting harmful gases. ‘i-Light’ also has various emotional functions for experiencing interaction and taste of light. For the purpose, portable LED camping lights were designed, first of all, and then a highly color rendering/full-color lighting module, a smart sensor module and an IOT device platform were developed. In addition, efforts were made to establish detailed data about emotional lighting contents and to develop a Web application based on them. Finally, prototypes of portable LED camping lights were made to get a test bench and usability evaluation from related organizations. According to the results, all of 12 developed emotional lighting contents and three IOT safety sensors were suitable and prototypes were satisfactory. This paper will suggest a direction about actual technical choices for development of contents and products integrating artificial intelligence and big data and about the procedure for materializing them.

TRS 거래에 관한 법적 연구 - 유형화를 통한 규제방안 마련을 중심으로 -

김희준 ( Kim Hee-jun ) 한국상사판례학회 2018 상사판례연구 Vol.31 No.3

TRS 거래의 구조는 지속적으로 진화하고 있는데, 일부 계약에서 규제를 회피하기 위한 의도가 발견됨에 따라 이에 대한 우려 역시 제기되고 있다. 불법적인 목적으로 악용되는 거래가 있다면 이의 위법성을 파악하여 법적 제재를 가해야 할 것이나 최근 일부 TRS 거래는 위법한 거래의 ‘실질’이 적법한 ‘형식’으로 적절히 포장되어 있어 접근이 쉽지 않다. 특히 TRS 계약 안에 내재되어 있는 거래의 동기는 당사자가 아니면 정확히 알기 어려운 특징을 지니는 점에서 더욱 그러하다. 본 연구에서는 국내에서 활용되고 있는 TRS 거래들을 동기별로 유형화한 후 거래의 법적 성격을 파악하여 구조화 하였다. 이와 같은 시도의 목적은 일부 TRS 거래가 규제를 회피할 목적으로 이루어지고 있음을 밝혀 이에 대해 적절한 법적 제재가 이루어질 수 있도록 하려는 데에 있다. 필자는 기본적으로 TRS 거래에 대하여 적절한 규제가 이루어져야 한다는 입장을 취하고 있으며 보다 구체적으로는 엄격한 법해석과 입법이 병행하여 이루어져 야 할 것으로 본다. 본 연구를 통한 논의들이 규제회피목적의 TRS 거래와 재벌총수일가의 사익편취행위를 근절하는 데에 일조할 수 있기를 기대한다. A total return swap is a contract between two parties. One party can transfer credit risk to the other party, while the other party is assuming that the rates he receives from the investor will be higher than the return on the asset. Total return swaps are primarily used by banks, other financial institutions and corporations. Some conglomerates are making total return swap agreements to get around the law in Korea. The purpose of this study is to regulate companies which uses total return swap contract as a means of contravening the law. Then On what base should the law legitimate the total return swap transactions avoiding regulations? To answer the questions, The author classified current total return swap contracts into five categories. This article also analyses the court cases to show how the Courts have applied the laws to total return swap agreements in Korea.
