Live weight, body length, hip and shoulder heights, heart girth, and metatarsal length were measured on 100 one to two years old Bali (Bos javanicus) bulls. Multiple regression of these measurements on live weight gave a prediction equation involving heart girth and body length (prediction $R^2$ = 0.845). These measurements were also used to derive several frame scores (FS). Live weight (Lwt) divided by FS was used as an index of body condition. Lwt/(length+hip height) was normally distributed and highly correlated with other normally-distributed condition indexes. This index was used to define five body condition scores. These were used to develop a five-point body condition scoring system in which the amount of fleshing over the vertebral processes, ribs, hindquarters, tail head, hooks, at the top of the neck, and the shoulders, the development of wrinkles in the skin above the hock and the neck, and the size of the dewlap, were used to describe the different body condition scores. Animals of score 1 had prominent hooks, shoulders, vertebrae and ribs, and hollow hindquarters and flat tailhead. Score 5 animals had rounded hindquarters, well-filled upper hind legs, small mounds of soft tissue were apparent on the tailhead, their hooks, necks, shoulders, vertebrae and ribs were well covered, and the dewlap was prominent.

In this paper, we investigate the degrees of freedom (DoF) of a multi-cell multi-user multiple-input multiple-output (MIMO) interference broadcast channel (IBC) with non-cooperation distributed base stations (BS), where each BS serves users of its corresponding cell. When all BSs simultaneously transmit their own signals over the same frequency band in the MIMO IBC, the edge users in each cell will suffer the inter-cell interference (ICI) and inter-user interference (IUI) signals. In order to eliminate the ICI and IUI signals, a distributed space time interference alignment (DSTIA) approach is proposed where each BS has only limited access to distributed moderately-delay channel state information at the transmitter (CSIT). It is shown that the DSTIA scheme can obtain the appreciate DoF gains. In addition, the DoF upper bound is asymptotically achievable as the number of antenna at each BS increases. It is shown that the DSTIA method can get DoF gains over other interference alignment schemes with delayed CSIT in literature. Moreover, the DSTIA method can attain higher DoFs than the IA schemes with global CSIT for certain antenna configurations.

Purpose: To analyze the relative position of the mandibular foramina (MnFs) in patients diagnosed with skeletal class III malocclusion. Materials and Methods: Computed tomography (CT) images were collected from 85 patients. The vertical lengths of each anatomic point from the five horizontal planes passing through the MnF were measured at the coronoid process, sigmoid notch, condyle, and the gonion. The distance from the anterior ramus point to the posterior ramus point on the five horizontal planes was designated the anteroposterior horizontal distance of the ramus for each plane. The perpendicular distance from each anterior ramus point to each vertical plane through the MnF was designated the horizontal distance from the anterior ramus to the MnF. The horizontal and vertical positions were examined by regression analysis. Results: Regression analysis showed the heights of the coronoid process, sigmoid notch, and condyle for the five horizontal planes were significantly related to the height of the MnF, with the highest significance associated with the MnF-mandibular plane (coefficients of determination ($R^2$): 0.424, 0.597, and 0.604, respectively). The horizontal anteroposterior length of the ramus and the distance from the anterior ramus point to the MnF were significant by regression analysis. Conclusion: The relative position of the MnF was significantly related to the vertical heights of the sigmoid notch, coronoid process, and condyle as well as to the horizontal anteroposterior length of the ascending ramus. These findings should be clinically useful for patients with skeletal class III mandibular prognathism.

본 연구에서는 모래다짐말뚝 (SCP)로 개량된 연약점토지반상의 성토시공에 있어서 최적설계조건에 대해 현행 설계법과 손실평가함수 및 1차 근사 2계 모멘트법 (AFOSM)에 기초한 신뢰성 설계법으로 비교 검토하였다. 결과를 요약하면 다음과 같다. 1) 안전율(Fs)와 파괴확률($P_F$)는 심한 비선형 관계를 나타냈고, Fs가 1.2로 증가함에 따라 $P_F$는 약 1%까지 급격한 감소를 나타낸 후, 안전율의 증가와 더불어 $P_F$는 점진적으로 감소하였다. 현행 설계법상의 기준 안전율 1.2는 둘의 관계에 있어서 일종의 임계값이며, 이들의 관계가 적절히 고려되어 정립되었다고 판단된다. 2) 최소기대총비용을 나타내는 안전율은 1.15부근으로 현행설계기준 1.2에 다소 못미치는 값으로 나타났고, 파괴확률은 1% 정도로 다소 컸다. 3) 응력분담비 n과 모래의 내부마찰각 ${\phi}$의 민감도가 연약층의 초기비배수강도 관련 변수들의 민감도보다 더 크게 나타났다. 이것은 n과 ${\phi}$의 변동 특성이 보다 해석결과에 큰 영향을 준다는 것과 이들 변동 특성은 SCP 개량지반상의 성토안정해석에 반드시 고려되어야 함을 의미한다. 4) 설계기준안전율 1.2 이상(파괴확률 0.1-0.3% 이하)에서 New Failure Point는 평균치에서 표준편차의 1~2배 가량 떨어져 있는 값을 나타냈다.

The purpose of this investigation was to evaluate of the specificity of Fusobacterium nucleatum subspecies-specific DNA probes using dot blot hybridization. To confirm whether the clinical isolates were F. nucleatum or not, 16S rDNA of them were cloned and sequenced. The sequencing data were used in homology search with database of GenBank. When the homology was above 98% compared with the nucleotide sequence of a certain bacteria, it was judged as the same species with the bacteria. 23 strains of F. nucleatum were isolates from subgingival plaque of periodontitis patient. The clinical isolates of F. nucleatum were classified into 10 groups using phylogenetic analysis of 16S rDNA sequence. F. nucleatum subspecies nucleatum-specific DNA probe Fu4(1.3 kb) reacted with genomic DNAs from 8 type strains of F. nucleatum and it reacted strongly with those from 8 clinical isolates. The Fp4(0.8 kb) reacted with F. nucleatum subsp. polymorphum ATCC 10953 and one clinical isolates. Fv35(1.9 kb) and Fs17(8.2 kb) probes reacted with genomic DNAs from F. nucleatum subsp. vincentii ATCC 49256 and F. nucleatum subsp. fusiform ATCC 51190, respectively. Our results showed that it is not enough to evaluate the specificity of F. nucleatum subspecies-specific DNA probes with only dot blot hybridization. Therefore, Southern blot analysis will be necessary to confirm the specificity of F. nucleatum subspecies-specific DNA probes.

This study was conducted to investigate the effects of mulberry fruit, mulberry leaves and silkworm powder with different mixing ratios on hepatic antioxidative system and lipid metabolism in streptozotocin-induced diabetic rats. Sprague-Dawley male rats weighing $100{\pm}10g$ were induced diabetic by 50 mg/kg bw streptozotocin and randomly assigned to following experimental groups; normal diet group (DM), 0.3% and 0.6% mulberry fruit diet groups (F and 2F), 0.3% mulberry leaves diet group (M), 0.3% silkworm powder diet group (S), 0.15% mulberry fruit+0.15% mulberry leaves diet group (FM), 0.15% mulberry fruit+0.15% silkworm powder diet group (FS), 0.1 % mulberry fruit+0.1 % mulberry leaves+0.1% silkworm powder diet group (FMS). The experimental diets were fed for 4 weeks. Hepatic SOD activity was not changed significantly by any of single or combined supplementations of mulberry fruit, leaves and silkworm powder but GSH-px and catalase activities were increased by the groups supplemented with two or three of the test ingredients (FM, FS, FMS) as compared with the DM group. Hepatic TBARS value was not reduced significantly by any of the supplementations but lipofuscin contents were significantly reduced in the FM, FS and FMS groups as compared with the DM group. Hepatic mitochondria and microsomal carbonyl values were reduced by the single and combined supplementations of the test ingredients. Hepatic HMG-CoA reductase activities were increased in the all supplementation groups as compared with the DM group. Hepatic total lipid and triglyceride contents were increased but cholesterol contents reduced in the supplemented groups. The effects on the enzyme activities, peroxide or its products and lipid contents were most remarkable in the FMS group. In conclusion, mulberry fruit, mulberry leaves and silkworm powder have the favorable effects on antioxidative system and lipid metabolism in the diabetic liver and the mulberry fruit, leaves and silkworm powder with equal ratio exert the synergistic effect expectedly to prevent diabetic complications.

A study on the conception rate of 885 cows and heifers bred under artificial insemination (AI) and natural service was carried out at AI sub-centers. A high conception rate was observed at first service in all breeding methods. It was revealed that the conception rates in AI with liquid semen (LS) were found to be 25.08, 18.58, 12.69, and 2.48% after 1, 2, 3 and 4 services, respectively. Inseminations of cattle with frozen semen (FS) were found to achieve 42.15, 14.46, 5.85, and 2.46% conception rates after 1, 2, 3, and 4 services, respectively. In natural service, conception rates were found to be 62.45, 6.75, 5.91, and 4.64%, respectively, after 1, 2, 3, and 4 services. Insemination of cows and heifers at mid-cycle had significantly (p < 0.05) higher conception rate as compared to early and late cycles. The existing AI machineries and breeding management need to be improved to achieve higher conception rate of dairy cattle under AI.

에디 공분산 방법(eddy covariance method)을 이용한 이산화탄소($CO_2$), 수증기($H_2O$), 현열(sensible heat)의 순생태계과환량[net ecosystem exchange (NEE)]은 에디 플럭스(eddy flux, $F_c$)와 저장 플럭스(storage flux, $F_s$)의 합으로 어림한다. 스칼라의 흡원과 발원의 세기와 분포, 연직 난류 혼합의 정도에 따라 스칼라의 변화율은 높이에 따라 다르게 나타난다. 따라서 정확한 $F_s$를 얻기 위해서는 프로파일 시스템을 운용하여 높이에 따라 달라지는 스칼라의 변화율을 고려하여야 한다. 하지만 아시아의 대부분의 농경지 관측지에서는 프로파일 시스템을 운용하지 않고, $F_c$ 관측 지점과 지면 사이에서 높이와 관계없이 스칼라 변화율이 동일하다는 가정하에 에디 공분산 시스템에서 관측되는 스칼라 변화율 만으로 $F_s$를 산정한다. 본 연구에서는 논에서 에디 공분산 관측 높이에서 측정된 $F_s$(프로파일 시스템에서 관측된 단일 높이의 스칼라만을 이용한 $F_s$, $F_s_{-single}$)와 프로파일 관측(에디 공분산 관측지점과 지면 사이의 여러 높이에서 스칼라 관측)을 이용한 FS와의 차이를 정량화하고, $F_s_{-single}$로 NEE를 산정할 때 발생하는 오차를 확인하기 위해, 경기도 여주에 위치한 청미천 농경지 플럭스 관측지(Chengmicheon Farmland Korea, CFK)에서 에디공분산 방법과 프로파일 시스템을 이용해 $CO_2$, $H_2O$, 기온($T_a$)의 $F_c$와 $F_s$를 측정하였다. $CO_2$, $H_2O$, $T_a$는 흡원과 발원의 강도와 분포, 대기 경계층의 안정도에 따라 높이별로 변화율이 달랐고, 그 결과 $F_s_{-single}$은 $F_s$를 과소 또는 과대 평가하였다[특히, 해질 녘과 해 뜰 녘(0430-0800h와 1630-2000h)에 $CO_2$의 $F_s$를 평균 21% 과소평가]. $F_s_{-single}$로 인해 발생하는 NEE 계산의 오차는 $F_{CO_2}$의 경우, 하루 중 시간에 따라 밤(2030-0400h), 해 질 녘과 해 뜰 녘에 각각 평균적으로 3%, 2%씩 $F_{CO_2}$를 과소평가했다. 이러한 차이는 $F_{CO_2}$의 야간 자료 보정과 분배의 과정에서 논의 탄소수지를 과소평가하게 할 수 있다. 이와는 다르게 LE, H의 경우 시간에 관계없이 거의 차이를 보이지 않았다.
