This experiment was conducted to evaluate the feed value of rice straw fermented with yeasts and waste sawdust after shiitake culture(WSSC). Nutrients disappearance and degadability rates of the rice straw were analyzed. Three different types of feeds were formulated. 1) Rice straw was mixed with WSSC, cam and molasses at the ratio of 1 :0.067 :0.18:0.02. This formula was used for control. 2) The mixture of rice straw, cam and molasses was anaerobically fermented at 30℃ for 6 days, and then WSSC was added (anaerobic treatment). 3) After WSSC addition into the pre-fermented mixtyre, two weeks of aerobic treatment period were provided (aerobic treatment). Korean rattles (Hanwoo) were used for in situ experiment. The results obtained from this research are as follows : 1. The contents of neutral detergent fiber(NDF), acid detergent fiber(ADF), cellulose, and crude protein(CP) in the aerobic treatment increased, while hemicellulose content clearly decreased, when compared to the control. However, chemical compositions of anaerobically treated diet were similar to those of control. 2. Lower dry matter(DM) disappearance in the rumen was occurred in the anaerobic treatment. The DM disappearance rates at 6 and 12 hours after feeding in the aerobic treatment were lower than those in control, but significantly increased from 24 hours after feeding. 3. The NDF disappearance rate was the lowest in the anaerobic treatment, and NDF disappearance rate in the aerobic treatment significantly increased from 24 hours after feeding. 4. When compared to the control, the ADF disappearance rate ip the anaerobic treatment was similar, but ADF disappearance rate in the aerobic treatment was greater. 5. Degradation rate of DM, NDF, and ADF in the rumen increased in the aerobic treatment, compared to the anaerobic treatment and control. Effective degradability of ADF was found to be higher in the aerobic treatment than that in the control by obtaining 9.4, 6.3, and 4.8% at K (passage rate) of 0.02, 0.05, and 0.08, respectively.

The following conclusion has been acquired by means of analizing the index number after conducting H.S.T on some 96 physical education experts( students ) and some 146 ordinary students in order to obtain the degree of cardiovascular endurance and the data on physical education aod training for the comparative study on Motor Fitness betwee the physical educational skilled students and the ordinary studets. 1. The average of index number of H.S.T. of physical educationally skilled students showed 88 which is very excellent, the ordinary students 79 which means good. So, the difference of average index number indicated 9. 2. 92.7 of Index number, the highest value was appeared to the physical educationally skilled students when they are at the age of 24, and 82.5 to the ordinary students when they are at the age of 21. The former has a tendency of increasing up to the age of 24, and the latter decreasing from the age of 22. 3. According to the survey by school year, the highest Index number of 89.1 was appeared to the physical educationally skilled students when they are in their Senior Year, and 85.9 to the ordinary students when they are at their Sophomore Year, So, the difference according to school year is very much in case of higher school year ( Junior year : 110.7%, 116.8% : Senior year) but not much in case of lower school year ( Freshman year : 105.7%, Sophomore year : 102.6% ) 4. As for the index number of those who smoke cigarett, that of physical educationally skilled students is 4 lower than the average index number, indicating 84 which is lower than the average of 99 of those who don't smoke. Ordinary students indicate 6 lower ( who smoke ) than the average index number, indicating 73 which is 13 lower than the average of 92 of those who don't smoke. Judging by this fact, it is abvious that smoking cigarett affects cardiovascular endurance.

임광철,설정자,Rim, Kwang-Cheol,Seol, Jung-Ja 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.3

스마트 정보통신시대에 데이터의 수는 기하급수적으로 증가하고 있다. 이에 데이터 발생지역과 발생상황을 실시간으로 파악하고 분석하는 것이 신속한 조치를 취하는 중요한 요소로 떠오르고 있다. 본논문에서는 분석자가 원하는 특성 데이터 발생지역의 국소적 판단을 하기 위하여 데이터 발생에 대한 값을 최하위 모듈에서부터 최상위 모듈까지 이어지는 루트를 역순으로 진행하면 데이터 발생과 동시에 분석이 가능하다. 먼저 군집분석에 대해 알아보고 군집원들의 합에 의한 분석법을 트리 구조에 병합하여 최하위 모듈부터 최상위 모듈까지 발생 특성값에 대해 수치로 치환하고 그 합을 도출하도록 설계하였다. 또한 특성값에 대한 가중치를 부여하여 원하는 값의 발생상황을 실시간으로 도출되도록 설계하였다. With the advent of the Smart information-communication era, the number of data has increased exponentially. Accordingly, figuring out and analyzing in which area and circumstance the data has been created becomes one of the factors for prompt actions. In this paper identifies how to analyze the data by implementing a route from the lowest module to highest one in an inverse order for the part judgement for the particular data. The script first identifies cluster analisys, paralizes the analysis using the sum of each factors of the cluster with the tree structure, and finally transpose the answer into number. Also, it is designed to place priority on particular answer, thereafter, draws the wanted answer real-time.

임광철,정영철,Rim, Kwang-Cheol,Choung, Young-Chul 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.1

ICT 생태계의 동인으로 전자정부는 그 형태의 변화를 가져온다. 이에 따라 스마트 전자정부 구현을 위해서 정부는 m-Gov 서비스를 활성화 하고, 이를 위해 기술정책을 수립할 필요가 있다. 따라서 본 논문에서 스마트 전자정부 구현 모형을 제시하고, 안전한 m-Gov의 인프라 구성을 위해 양자암호 시스템을 서버보안에 응용할 수 있는 정보보안 기술정책으로서 보안 알고리즘을 제안한다. 이것은 결국 보안성, 안전성, 경제성이 확보된 대국민 및 기업에 대한 스마트 전자정부 서비스를 제공하는 행정이념을 추구하는 것이다. As ICT Ecosystem does, electronic government changes in its form. Accordingly, in order to realize Smarter m-Gov, the governments need to vitalize m-Gov services and enact technology policy. Therefor, this manuscript suggests possible model of m-Gov realization and security algorithm as a technology policy which applies quantum cryptography system to server security for the construction of secured m-Gov's infrastructure. What the manuscript suggests seeks administrative ideas of Smarter m-Gov's services which contain security, stability, and economic feasibility for the benefits of nation and enterprises.

임광철,임동호,Rim, Kwang-Cheol,Lim, Dong-Ho 한국정보통신학회 2016 한국정보통신학회논문지 Vol.20 No.3

사물인터넷과 사회구조의 다변화로 사용자들은 접속과 인증의 필요성이 날로 증가하고 있다. 인증 필요성의 증가는 새로운 패스워드의 생성을 요한다. 사용자들은 암기의 편리성을 위하여 동일한 패스워드를 사용하고자 한다. 하지만 시스템 관리자들은 공격에 대한 안전성을 이유로 사용자로 하여금 서로 다른 패스워드와 특수기호를 사용한 패스워드의 사용을 요구한다. 서로 다른 패스워드와 특수기호를 포함한 패스워드는 사용자의 암기능력 범위내에서 허용치를 초과하는 것을 보인다. 이는 패스워드 관리 측면에서 매우 부정적인 결과를 가져 온다. 본 논문에서는 사용자의 암기를 요구하지 않는 선호기호 패스워드 시스템을 제안한다. 먼저 통계적 안전도를 증명하기 위한 설문조사를 하였고 이를 바탕으로 선호기호를 이용한 진화형 패스워드 시스템을 설계하였다. 선호기호 패스워드는 기존 비암기형 패스워드 시스템인 생체정보나 키스트로크, 마우스 패턴에 비해 설치비용과 사용편리성면에서 우수함을 보인다. User requirements for access and authentication increase daily because of the diversification of the Internet of Things (IoT) and social structures. The increase in authentication needs requires the generation of new passwords. Users want to utilize the same passwords for memorization convenience. However, system administrators request each user to use different passwords, as well as passwords that include special symbols. Differnet passwords and including special symbols passwords seem to exceed the tolerance range within your memorization skills. It fetches a very negative consequences in terms of password management. This paper proposes a preference symbol password system that does not require memorization by users. First, a survey is conducted to prove statistical safety, and based on this, an evolution-type password system that uses preference symbols is designed. Preference symbol passwords show superiority with respect to installation cost and convenience, compared with conventional non-memorizing password systems such as biometrics, keystrokes, and mouse patterns.

본 실험은 알코올 발효사료(alcohol 함량; 3.0∼3.2%, lactate 함량; 3.0∼3.5%) 처리가 한우 반추위내 혈액성분 및 비육능력에 미치는 영향을 검토하기 위하여 한우에 비지박 알코올 발효사료(Alcohol-fermented soybean curd dreg : AFS) 및 맥주박 알코올 발효사료(alcohol fermented brewery grain's : AFB)를 급여하여 평균체중이 329㎏인 한우 거세우 13두와 평균체중이 337㎏인 한우 비거세우 20두를 공시하여 증체량, 사료섭취량, 혈액성분, 혈중 알코올 함량을 측정하여 다음과 같은 결과를 얻었다. 거세우에서 비육전기의 일당증체량 및 사료효율은 알코올 발효사료 급여구들이 대조구에 비해 개선되는 경향을 보였으며, 비육후기의 일당증체량은 처리에 따른 유의적인 차이를 나타내지 않았으며, 비육후기의 사료효율은 알코올 발효사료 급여구가 개선되는 경향을 보였다. 비거세우에서 일당증체량 및 사료효율은 알코올 발효사료 급여로 개선되는 경향을 보였으나 유의성은 나타나지 않았으며, 비육 후기에는 개선효과가 없는 것으로 나타났다. 혈중 알코올 농도는 알코올 발효사료 급여구가 시험사료 급여 2시간 후에 유의적으로 높게 나타났으나(p<0.05), 사료급여 4시간째에는 급여전의 수준으로 낮아졌다. BUN 농도는 거세우가 비거세우에 비해 높았으며(14.3 vs 10.97 ㎎/㎗, p<0.05), 혈중 creatinine 농도는 거세우가 비거세우보다 낮았다(1.39 vs 1.49㎎/㎗, p<0.05). 혈중 cholesterol 농도는 전체적으로 체중이 증가함에 따라 증가하는 것으로 나타났고, 혈중 glucose 농도는 알코올 발효사료 급여로 비거세우에서는 감소하는 경향을 보인 반면 거세우에서는 증가하는 것으로 나타났다. 혈중 IP 농도는 알코올 발효사료 급여로 거세우 및 비거세우 모두 증가되었다.(p<0.05). This study was conducted to know the feeding effects of alcohol-fermented feedstuffs (alcohol concentration: 3.0∼3.2 %, lactate: 3.0∼3.5%) on the blood metabolites and fattening ability. Alcohol-fermented soybean curd dreg (AFS) and alcohol fermented brewery grain (AFB) were fed to 13 Korean steers (average body weight, 329㎏) and 20 Korean bulls (average 337㎏ B.W), and body weight gain, feed conversion rate, blood metabolites and blood alcohol concentration were analyzed. The feed conversion rates of steers at both fattening and finishing period were improved by feeding alcohol-fermented feedstuffs. However, improvement of daily body weight gain was observed only at fattening period. In bulls, body weight gains and feed conversion rate were also improved at fattening period (but not at finishing period) by feeding of alcohol-fermented feedstuffs, although a statistical significance was not detected. Blood alcohol concentrations of AFS and AFB group were significantly increased (p<0.05) at 2 hours after feeding, but dropped to the initial level at 4 hours after feeding. Blood urea nitrogen(BUN) concentrations of steers were higher than those of bulls (14.3 vs 10.97 ㎎/㎗), but creatinine was lower in steers than in bulls (1.39 vs 1.49㎎/㎗). Blood cholesterol concentration was generally proportional to the increment of body weight. While the blood glucose content was decreased in bulls by feeding alcohol-feedstuffs, it was increased in steers. Blood inorganic phosphorus(IP) level was increased in both steers and bulls.

The IoT era in situations where network connectivity is constantly in progress . IoT is a convenience but a gift of life made impossible to security vulnerabilities also excluded. Endpoint security according to this situation it goes to a further aspect as before. In this paper, we first look for the big two parts of SBC, NAC and endpoint were analyzed comparing them. After using the strengths and weaknesses of the NAC and SBC looked at inverse order tree structure for designing algorithms for hybrid endpoint. Intermixing the NAC and SBC mathematical model in inverse order tree structure of the weight inverse order tree structures assigned a weight to each node in the inverse order tree structure is designed for hybrid endpoint security algorithm. IoT시대가 도래하여 네트워크 연결이 상시적으로 진행 되는 상황이다. IoT는 생활의 편리함을 선물하였지만 보안 취약성 또한 배제할 수 없게 만들었다. 이러한 상황에 맞춰 엔트포인트 보안은 예전과 다른 양상으로 진행된다. 논문에서 먼저 엔드포인트의 거대 두 파트인 NAC와 SBC에 대하여 살펴 보고 이들을 비교 분석 하였다. 이후 이둘의 장단점을 이용하여 혼합형 엔드포인트 알고리즘을 설계하기 위한 역순트리형 구조를 살펴보았다. 역순트리구조에서 각각의 노드에 가중치를 부여한 가중역순트리 구조의 수학적 모델을 살펴보고 역순트리구조에 NAC와 SBC를 상호 혼합하여 혼합형 엔트 포인트 보안 알고리즘을 설계하였다.
