In this study, the methodology for measuring the structure of the Korean defense market and the competition status, and the characteristics of the Korean defense industry and the market are examined. To analyze the structure of the Korean defense market and the competition status, the market share, concentration ratio, and the Herfindal-Hirschman index are employed based on the annual sales of major Korean defense companies. On a basis of the result of the analysis, the suggestions for the Korean defense market to escape from the monopolistic market to be a competitive geographical market are presented. To present the suggestions, markets that have a similarity with the dense market are analyzed. The government's support policy, the selection of the companies led by the government, and the cost of the military are suggested for the defense market on a basis of analyzing similar markets. With the suggestions, when the government pursues the policies, the defense market sticking to principles and fairness is created and the efficiency of the companies operation is achieved, by enhancing the structure of the market fundamentally and the development of the policies in the industry's perspective.

주요 방산물자의 경우 최저가 입찰 방식의 채택은 방산업체들 간 물량부족에 따른 과다 수주 경쟁으로 인해 터무니없는 낮은 가격으로 업체가 결정되는 경우가 발생되고 있다. 이러한 제도 운영은 방산 물자의 기술 개발 촉진에 장애요인으로 작용할 뿐만 아니라 방위력 증강은 물론 방위산업 육성에도 많은 지장을 초래할 우려가 있다. 본 논문에서는 실천 가능한 방위산업 입찰제도를 도출하고 입찰제도를 개선하기 위해서, 현재 방산청에서 실시하고 있는 최저 입찰제도의 문제점을 알아보고, 미국, 유럽과 일본의 정부조달제도와 방위산업에서의 입찰방식을 살펴본다. 그리고 협상에 의한 계약 체결시 적용하는 회계예규의 평가산식 불합리성 및 문제점을 고찰하고, 국내 방산업체가 느끼는 입찰제도의 문제점을 설문을 통해 파악/분석함으로 방위사업청 제안서 평가 지침에 대한 적절한 방식을 제안하고자 한다.

The average milk fat content in goat milk was 3.88% on yearly basis. The milk fat content of 3.8% during summer season was lower than 4.2% during winter season. Total solid content increased in proportion to milk fat. When goat milk was stored at 4℃ for 24 hr, short-chain FFA(C4:0~C10:0) and medium- and long-chain FFA(C12:0~C18:1) increased about 106% and 203%, respectively. Induced lipolysis of goat milk by homogenization increased short-chain FFA and medium- and long-chain FFA by 22% and 199%. When goat milk was treated with calf lipase, there was increase of short-chain FFA by 9 times greater than increase of medium- and long-chain FFA by 5.6 times. Treatment with lipases from Candida rugosa and Pseudomonas fluorescens resulted in increase of medium- and long-chain FFA by 34 and 162 times, respectively, which was greater than increase of short-chain FFA by 6 and 14 times, respectively. Lipolysis in goat milk stored at 4℃ for 24 hr was correlated with LPL activity in goat milk(r=0.5635). Off-flavor of goat milk was correlated with LPL activity(r=0.5777). Milk fat content was negatively correlated with LPL activity(r=－0.4627). Palmitic acid content in goat milk was correlated with off-flavor(r=0.7226).

Since the end of the Cold War in the 1990s, European countries have cut defense costs and reduced armaments as an era of peace without large-scale wars continues, and as a result, the West's defense industry base has gradually weakened. On the other hand, South Korea, the world's only divided country, was able to achieve high growth in the defense industry as a result of continuous arms strengthening in the face of North Korea's nuclear and missile threats. With the rapid increase in demand for conventional weapons systems and changes in the structure of the global defense market due to the Russia-Ukraine war, Korea's weapons system drew great attention as a large-scale defense export contract with Poland was signed in 2022. In 2023, K-Defense ranked ninth in the world's arms exports and aims to become the world's fourth-largest defense exporter by 2027. Therefore, this study analyzed the case of Korea-Poland defense exports to derive problems, and presented development strategies related to export revitalization of K-Defense, a national strategic industry. In order for the defense industry to become Korea's next growth engine, it is necessary to establish a defense organization, prepare government-level measures to protect defense industry technology, and expand military and security cooperation with allies linked to defense exports.

Fatty acid methyl esters, also referred to as biodiesel, have been determined to have a great deal of potential as substitutes for petro-diesel. In order to enhance productivity in the biodiesel production process, feedstocks were previously recommended to be anhydrous, with a free fatty acid content of less than 0.5%. In this study, the effects of several catalysts, methanol molar ratio, catalyst amount, and reaction time on the reduction of free fatty acid level were studied with a simulated feedstock consisting of 20% oleic acid in rapeseed oil. Ferric sulfate was selected as the best catalyst. Increasing the catalyst amount and methanol molar ratio is very effective in decreasing the acid value of the simulated mixture. Our results may provide useful information with regard to the development of more economic and efficient free fatty acid removal system.

Free fatty acids of two brands of domestic butter were isolated directly by a modified silicic acid column chromatography, and were analyzed by gas liquid chromatography. $C_{18}$ FFA congeners $(C_{18_0},\;C_{18:1},\;C_{18:2}\;and\;C_{18:3})$ were the predominant components (52.83% in brand A and 47.50% in brand B), followed by $C_{16}$FFA (29.39% in brand A and 30.52% in brand B) and $C_{14}$FFA (11.85% in brand A and 13.76% in brand B). The other FFA were present as minor components (0.29-3.87%). Concentrations of four FFA $(C_4,\;C_6,\;C_{10}\;and\;C_{12})$FFA which would be expected to contribute strongly to hydrolytic rancidity off-flavors were below individual threshold level, except $C_4FFA$ (56 ppm) in butter B.

The present study examined the formaldehyde (HCOH) emission characteristic of various wood-based panel used in interior design, and measured changes in formaldehyde emission when a number of VOC reduction methods were applied. Formaldehyde emission showed a clear tendency of increase with the rise of temperature, and the concentration of formaldehyde emitted changed according to the preprocessing condition before measuring. Formaldehyde emission from wood board after bake out treatment was lower than that of the control group. When specimens were coated with urethane, cashew, water, oil stain, they generally showed the decrease of formaldehyde emission, although varying according to finishing material, and when edge sealing was applied the decrease became significant. $TiO_2$ coating was more effective in decreasing formaldehyde under ultraviolet lamps than under ordinary lamps. When the irradiation of ultraviolet lamps gets longer, formaldehyde emission decreased.
