In times of current warfare, importance of civil military operations(CMO) is more on the rise because the military winning does not couple the political winning immediately. For this reason, CMO Model Development Program has been commenced by ROK JCS since FY 2014. As CMO is non-kinetic operations which is focused on civilians, it depends on the commander's decision that reflects the results of the evaluation of the CMO performance level. The evaluation of CMO performance level is a very important factor of this model. So, I decided my subject a study of simulation method for evaluation of CMO Performance level. It is affected in CMO performance level by the occurrence of some event, and the achievement results of CMO for the response action on such event is evaluated by the 5 factors(administration level, security level, infrastructure level, humanitarian support level, friendship level) on the evaluation of CMO performance level. Even more it is affected in achievement of new CMO and new event by evaluation results. In this study, I provided a methodology of how apply the evaluation results and how simulate the achievement results of CMO performance with the 5 factors on the evaluation of CMO Performance level. Also this study is expected that it will be highly contributed to training and exercise in CMO branch in ROK JCS, when CMO Model Development Program is done as a new model applied such evaluation factors matching military environment in the Korean Peninsular, and applied this simulation method for evaluation of CMO Performance level.

국내 제약 산업은 상위 30대 기업이 전체 생산 매출의 55.1%를 차지하는 불균형적인 구조를 가지고 있으며, 중소업체들은 공급자 과잉의 힘든 상황 속에 처해 있다. 이러한 가운데 중소제약업체를 중심으로 기존 설비를 활용하여 외국 제약회사의 Original 의약품을 복제한 Generic 의약품을 생산하여 납품하는 OEM/ODM 방식의 위탁생산이 증가하고 있다. 또한 글로벌 바이오의약품을 중심으로 CMO(Contract Manufacturing Organization) 생산에 대한 관심이 높아지고 있다. 본 연구에서는 의약품 위 수탁 사업에 있어서 영업사원의 핵심역량인 정보제공, 전문성, 판매기술, 태도 및 관계형성, 업무유연성이 고객 만족에 미치는 영향을 분석하여 CMO업체의 경쟁력 강화를 위한 방안을 제시하고자 한다.

Efficient snow-removing work is one of important processes of winter road management. Calcium chloride has been used as a typical deicing agent in Korea. It presents superial performance as snow deicing agents, however it has been known to give serious environmental problem and to deteriorate durability of concrete structure in road by corrosion. The environment-friendly road deicing agents made from the waste material which is liquid phase organic matter that is Ca Mg and reactant of organic acid (nitric acid and propionic acid) have been introduced by number of researchers. They indicated the calcium magnesium salt of organic acids have advantage over the calcium choride in terms of lower production unit cost by resources recycling and can solve environmental problem and durability deterioration of structures. In this study, the deicing performance of calcium magnesium salt of organic acids(CMO) is investigated based on the series of experiments including the test for heat of dissolution, freezing point, ice melting test and ice penetration test.

In Intensity Modulated Radiotherapy (IMRT), radiation is delivered in a multiple of Multileaf Collimator (MLC) subfields. A subfield with a small leaf-to-leaf opening is highly sensitive to a leaf-positional error. We introduce a method of identifying and rejecting IMRT plans that are highly sensitive to a systematic MLC gap error (sensitivity to possible random leaf-positional errors is not addressed here). There are two sources of a systematic MLC gap error: Centerline Mechanical Offset (CMO) and, in the case of a rounded end MLC, Radiation Field Offset (RFO). In IMRT planning system, using an incorrect value of RFO introduces a systematic error ΔRFO that results in all leaf-to-leaf gaps that are either too large or too small by (2ㆍΔRFO), whereas assuming that CMO is zero introduces systematic error ΔCMO that results in all gaps that are too large by ΔCMO = CMO. We introduce a concept of the Average Leaf Pair Opening (ALPO) that can be calculated from a dynamic MLC delivery file. We derive an analytic formula for a fractional average fluence error resulting from a systematic gap error of Δ$\chi$ and show that it is inversely proportional to ALPO; explicitly it is equal to, (equation omitted) in which $\varepsilon$ is generally of the order of 1 mm and Δx=2ㆍΔRFO+CMO. This analytic relationship is verified with independent numerical calculations.

본 논문에서 3치가산기와 승산기(multiplier)는 전류모드 CMOS에 의해서 구현된다. 첫째, 3치 T-gate를 집적회로 설계의 유효 가용성을 갖고 있는 전류모드 CMOS를 이용하여 구현한다. 둘째, 3치 T-gates를 이용해 회로가 유한체 GF (3)에 대하여 2변수 3치 가산표 (2-variable ternary addition table) 및 구구표 (multiplication table)가 실현되도록 구현한다. 마지막으로, 이러한 동작 회로들은 1.5 CMOS 표준 기술과 $15{\mu}A$ 단위전류(unit current) 및 3.3V 소스 전압 (VDD voltage)에 의해 활성화 된다. 활성화 결과는 만족할 만한 전류 특성을 나타냈다. 전류 모드 CMOS에 의하여 실행되는 3치가산기 및 승산기는 단순하며 와이어 라우팅(wire routing)에 대하여 정규적이고, 또한 셀 배열 (cell array)과 함께 모듈성 (modularity)의 특성을 갖고 있다.

Characteristics of the sol-gel derived (Ba1-xPbx)TiO3 powders are compared with those of powders prepared by the calcining ofmixed oxides method (CMO) and molten salt synthesis method(MSS). The sol-gel derived powder has a higher surface area (50$m^2$/g) than those of CMO(3.8$m^2$/g) and MSS(11.5$m^2$/g) derived powders. In the sol-gel method, the (Ba1-xPbx)TiO3 was synthesized at $600^{\circ}C$ for 1hr, indicating that this method has a crystalline temperature 20$0^{\circ}C$-30$0^{\circ}C$ lowr than those of the CMO and MSS methods.

The emergence of Security Token has revolutionized the way assets are traded, bringing efficiency, transparency, and accessibility to the market. However, the Real Estate Security Token market faces challenges, particularly in terms of liquidity. The CMTO(Collateralized Mortgage Token Obligation) model addresses this issue by introducing a novel approach that combines the benefits of NFT(Non-Fungible Token), STO(Security Token Offering), and CMO(Collateralized Mortgage Obligation) techniques to enhance liquidity and promote investment in Real Estate Security Token. The CMTO framework functions by allowing DABS token investors to leverage their tokens as collateral for loans. These token-collateralized loans are pooled together and form the basis for issuing Sequential CMO named CMTO. The CMTO represent a diversified portfolio of token-collateralized loans, providing investors with options based on their financial goals and risk preferences. By implementing CMTO, the Real Estate Security Token market can overcome liquidity challenges, attract a broader range of investors, and unlock the full potential of digital assets in the real estate industry.

I examine the relationship between values and security designs of MBS(mortgage-backed securities), using four different types of them. To this end I consider a pass-through and three different kinds of CMOs(collateralized mortgage obligations). It turns out that the pass-through has the lowest value and that, among CMOs, that of a senior-mezzanine-subordinate design has the highest value. This implies that CMOs of a simple and extreme design, like that of a senior-subordinate design, are not likely to be the best CMOs for risk averse buyers. Another critical finding is that the optimal security design of CMOs or MBS does exist in the form of an interior solution. This indicates that MBS issuers could charge higher prices of MBS given their underlying mortgages by tailoring MBS security designs to the needs or utilities of MBS buyers, usually by removing and combining risks of component tranches of MBS. Accordingly a thorough study of realistic utility functions of MBA buyers could enhance the values or prices of MBS to be issued.
