The purpose of this experiment is to clarify the additional effect of antibiotics for the chicken breeding feed. This experiment was carried out with 6,560 individuals which were collected from four farms, Dugil, Hyubhoi, Sanggog and Kumsan. The duration of this experiment was 6 months from July to December in 1981. 1. Body weight and body gain. (1) The range of the body gain was 1.91-7.60% The most effective sections was T$_3$, and the effect was T$_2$, T$_4$, T$_1$, T$\sub$5/ in order. (2) The environmental sanitation of the Sanggog farm was not so good. In this farm the body gain was severely occurred in T$_3$ and T$_2$ sections. Mere gain obtained from T$\sub$5/ section. (3) The environmental sanitation was good in Dugil, Hyubhoi and Kumsan. A little body gain was occurred in these farms, but differences were shown according to the place or breeds. 2. Amount of feed intake feed conversion ratio. (1) Amount of feed intake was increased 0.13-3.19%, and feed conversion ratio was improved 1.68-4.62% compared with control. T$_3$ section showed high percent and T$_4$ T$_1$, T$\sub$5/, Is, C in order. (2) The keeping method of the chicken breed in Hyubhoi was floor brooding. From Hyubhoi and Sanggog farms, the efficiency was increased 9.4-9.8%. (3) From Dugil and Kumsan, the rate of improvement was low. 3. Mortality : Mortality was merely decreased in Sanggog and Kumsan farms which the sanitary and fowl caring conditions had been had, by additional antibiotics. But there was no worthy effect. 4. The ratio of carcass and the degree of skin coloration. The additional antibiotics in feed had no effect on the ratio of carcass but had the influence on the yellowish skin coloration. Skin coloring was good in T$\sub$7/ section and T$_1$, T$\sub$6/, T$_4$, C, T$_3$, T$\sub$5/, T$_2$ in order. 5. Economical efficiency (1) The addition of the antibiotics in feed increased 3.76-10.95% of gross earning. The highest earning was occurred in T$_4$ section and T$_3$, T$_1$, T$_2$, T$\sub$5/, C sections in order. (2) The earning rate was influenced by the antibiotic products. (3) In Dugil and Kumsan farms, there was no difference in earning, however, in Hyubhoi and Sanggog farms there was wide difference in earning. Conclusionally, the addition of antibiotics in chicken breeding feed is necessary. Especially in bad condition of environmental sanitation and floor brooding, the effect of additional antibiotics is clear. Selection of antibiotics from various kinds, maker's confidence and quality problems are important.

To improve environmental problem as globally climate changes, domestic and foreign government have been trying to reduce green gas emitted by all industries. With making the green building certification system that assess the substantiality and energy performance of building, a governments have been using by a way for reducing green gas emitted in building industry. G-SEED(Green Standard for Energy & Environmental Design) developed in Korea have been reinforcing, and a number of projects certifying the G-SEED have been increasing continuously. As a demand of G-SEED certification is rising, a question on the additional cost data as certifying G-SEED is rising. It is because additional cost as getting the certification is important fact for G-SEED level decision and whether getting the certification or not. Therefore, this study analyzed additional construction cost as certifying G-SEED through performance improvement and design change of general office building not to get G-SEED. In conclusion, an additional construction cost ratio of G-SEED projects to the reference building is drawn as certified level; +0.26%, silver level; +2.29%, gold level; +3.89%, and platinum level; +5.48%.

Purpose: The purpose of this study was to evaluate the applicability of braden scale to assess pressure ulcer risk patients and to identify additional risk factors of pressure sores in an neurologic intensive care unit. Method: The subjects of this study were 66 patients in neurologic intensive care units. Data was prospectively collected from Sep. to Dec., 2002. Data were analyzed by mean, percentage, t-test, chi-square, discriminant analysis using Spss pc+. Result: The results of this study were as follows: 1) There was a significant difference between scoring of braden scale and pressure ulcer development. The subscales that predicted pressure ulcer development using braden scale only were sensory perception, moisture, mobility, friction & shear. By using these subscales, sensitivity was 86.7%, and specificity was 61.1%, and total hit ratio was 72.7%. 2) Additional pressure ulcer risk factors which showed significance for discriminating two group were protein, albumin, gender, level of consciousness, pattern of bowel elimination. By using the combination of these additional risk factors in addition to the braden scale, total hit ratio increased to 84.8%. Conclusion: This data suggest that albumin, protein, gender, level of consciousness, pattern of bowel elimination in addition to the braden scale should be included in the pressure sore assessment tool.

Conventional viewing angle switching electrode requires pixel division and additional liquid crystal panel. Hence the conventional viewing angle switching has low aperture ratio and high thickness. In this paper we proposed new viewing angle switching using hybrid aligned nematic mode by fringe-field electrode field (named HAN-FFS) with single liquid crystal panel. The fringe-field switching electrode is located at the bottom, and the additional common electrode is located at the top of the cell to control viewing angle. The proposed device is free from additional liquid crystal panel and pixel division. Consequently, the suggested structure has not only high aperture ratio but also show an excellent potential for viewing angle switching.

본 논문은 음성인식 시스템에서 정확도를 높이기 위해 후처리 단계에서 후보 단어들의 엔트로피 정보를 이용하였다. 기존의 우도비 검출방법은 음성 데이터에 따라 음성인식 시스템의 성능이 변하고 N개의 후보단어들의 우도값이 비슷하여 오인식 발생확률이 높았다. 그러나 본 눈문에서는 각 후보 단어들의 엔트로피 값보다 인식대상 단어 외의 단어들의 엔트로피 값이 상대적으로 낮은 후보를 거절하는 후처리 방법을 사용하여 음성 데이터에 독립적이면서도 변별력을 높인 정확한 음성인식 시스템을 얻을 수 있었다. 실험 결과 본 논문에서 제안하는 엔트로피에 의한 후처리 방법은 우도비에 의한 방법보다 인식 시스템의 성능을 false alarm이 20%일 때 최대 3.6% 향상시킬 수 있었다.

Using a device composed of two lateral pressure plates (LPPs) and a steel reinforcement bar to apply horizontal pressure on slope surfaces, a newly developed prestress-reinforced embankment (PRE) is proposed, to which can be adopted in strengthening railway subgrades. In this study, an analytical model, which is available of calculating additional confining stress (σ_H) at any point in a PRE, was established based on the theory of elasticity. In addition, to verify the proposed analytical model, three dimensional (3D) finite element analyses were conducted and the feasibility in application was also identified and discussed. In order to study the performance of the PRE, the propagation of σ_H in a PRE was analyzed and discussed based on the analytical model. For the aim of convenience in application, calculation charts were developed in terms of three dimensionless parameters, and they can be used to accurately and efficiently predict the σ_H in a PRE regardless of the embankment slope ratio and LPP side length ratio. Finally, the potential applications of the proposed analytical model were discussed.

Gastrointestinal cancer 환자의 약 20%가 진단 당시에 이미 간에 전이가 된 상태에서 발견된다. Gastrointestinal cancer 환자에서 PET/CT 검사 시 Liver 추가 촬영을 함으로써 영상의 질적 변화에 대한 유용성을 평가하고자 하였다. 검사대상은 2015년 9월부터 2016년 2월까지 본원에 내원하여 Gastrointestinal cancer 진단을 받은 152명을 대상으로 PET/CT 검사 후 Liver 부위를 추가를 촬영하였다. Standard 영상과 추가 영상에서 같은 Level의 관심영역을 설정하여 Signal to Noise Ratio(SNR), Standardized Uptake Value(SUV), Tumor/Normal(T/N) ratio의 변화를 통한 영상의 질적변화를 평균값을 산출하여 비교 평가한 결과 SNR은 standard $17.7{\pm}10.3$, 추가영상 $22.3{\pm}9.7$, $SUV_{max}$는 각각 $6.7{\pm}2.8$와 $7.6{\pm}3.2$, T/N ratio는 standard는 $2.1{\pm}0.6$, 추가촬영에서는 $2.5{\pm}0.8$로 분석되었다. 이는 통계적으로 유의한 차이가 있는 것으로 나타났다. SNR의 변화량이 가장 큰 것으로 나타났고 Liver 추가 촬영에 따른 SNR과 $SUV_{max}$, T/N ratio는 상대적으로 Standard 보다 높게 나왔고 Liver 추가 촬영을 통한 영상의 질적 향상은 간 전이가 있는 암 환자를 판독 하는데 있어서 유용한 검사 방법이라고 사료된다.
