The functional deformity following removal of the maxilla is considerable, especially following maxilla cancer excision. Rehabilitation of oral and maxillofacial region used to be very difficult with prosthesis or traditional flaps. Temporal muscle and fascia flaps have been described for immediate reconstruction following hemi-maxillectomy, but not total maxillectomy. The muscle and superficial fascia of the temporal area differ in their physical characteristics, vascular supply and clinical applications. Both can be employed independently or simultaneously as regional flaps in the reconstruction of a variety of complex craniofacial defects. Four case is presented in which 3 case maxilla cancer, one case non-union after maxilla fracture, and all case showed successful use of this flap. Only one patient developed partial necrosis of the flap ; significant necrosis did not occur in any other patient. This present paper reviews the anatomy, surgical technique and utilisation of temporal muscle and fascia flaps.

안양시의 지방재정은 경기도 내 타 도시에 비해 양호한 상태이며 상위권에 속하고 있다. 재정자립도는 2002년에 83.0%로서 경기도 내 5번째로 도내의 타 도시에 비해 비교적 높은 편이나 중요한 사실은 재정자립도가 매년 하락하고 있고, 투자비의 경우 안양시는 타 도시에 비해 높은 편인데다 점진적인 증가를 보이고 있어 지역사회에 대한 복지 기반 조성과 주민의 복지생활을 위해 바람직한 상황이지만, 경상비의 비중이 31.9%로 경기도 내 타 도시에 비해 가장 높아 탄력적인 예산운영에 한계가 있음을 보여주고 있다. 주민 1인당 지방세 부담액을 보면 안양시의 경우 2002년에 207,000원으로 경기도내 타 자치단체에 비해 비교적 지방세 부담액이 적은 것으로 나타났다. 세입부문에서의 문제는 전체세입 중 자주재원에 속하는 지압세와 세외수입 비중이 매년 감소하는 경향을 보인다는 점이고, 교부금과 보조금 등 의존재원이 늘고 있다는 점이 자율적인 지방자치 실현에 우려되는 바이다. 다행히도 정부혁신지방분권위원회는 7월 29일 재정 ? 세제 개혁 로드맵을 발표하였는 바 그 요지를 보면 중앙정부가 갖고 있는 기능을 과감하게 지방정부로 이양하면서 중앙정부가 움켜쥐고 있던 재정 및 예산도 함께 지방으로 이양하겠다는 것이다. 이제 이에 대한 구체적이고 실천적인 법적 ? 제도적 개선을 기대해 본다.

The purpose of this study was to obtain information on the working environment, rate of environmental measurement over TLVs, the number of workers who were exposed to hazardous agents and, the examined rate of special health examination(SHE) in different types of industries. Authors investigate the reports on the working environmental status of the 101 industries in Cheonan area and result of SHE of those industries. The results were as follows : 1. Out of 101 industries under study, only 54 industries took special health examination. 2. While 85.3%(6,590) of 7,726 workers working in 101 industries were exposed to one or more hazardous agents, 88.4% of 5,867 workers working in 54 industries with special health examination were exposed to those agents & 75..4% of 1,859 workers working in 47 industries without any special health examination were exposed to those agents. But according to the criteria of selecting eligible workers for special health examination, only 32%(1,935/5,867) of total workers in the later industries were classified as eligible for the special health examination. 3. While rate of environment measurement of 101 industries TLVs who 25.5%, that of 54 industries with SHE was 29.8 & that of 47 industries without SHE was 16.1%, while the rate of noise and dust measurement over TLVs of 54 industries with SHE was 31.7%, and 25.3%, those of 47 industries without SHE was 13.6% & 35.6%, among 54 industries with SHE the rate of environmental measurement over TLVs was highest in clothes & leathers(47.0%) and that of foods(32.3%) and primary metal(31.3%). One the other hand, among 47 industries without SHE the rate of environmental measurement over TLVs was highest in paper & printing(44.9%) and that primary metal(15.8%), metaloid mineral(15.5%). 4. The examined rate of SHE of 54 industries was 92.7% as a whole. By type of industries the rate of primary metal(221.4%), foods(181.7%), chemicals(120.4%) were exceeded expected percent(100%) but the rate of metalloid mineral(53.0%), paper & printing(63.8%), machinery(72.2%) were far below the expected percent. 5. Only 4.7% of total workers working in 47 industries without SHE were classified as eligible workers for SHE. Among those eligible workers 48.9% were belonged to potential workers for SHE of noise. 6. The response rate of questionnaire was 70.4%(38/54) in 54 industries wirh SHE & 48.9%(23/47) in 47 industries. The necessity of environment measure was positively answer in 81.6% of 38 with SHE & 87% of 23 without SHE. On the other hand, the necessity of SHE was positively answered in 68.4% with SHE & 21.7% without SHE.

음성인식을 위한 변환 공간 모델에 근거한 순차 적응기법

김동국,장준혁,김남수 한국음성과학회 2004 음성과학 Vol.11 No.4

In this paper, we propose a new approach to sequential linear regression adaptation of continuous density hidden Markov models (CDHMMs) based on transformation space model (TSM). The proposed TSM which characterizes the a priori knowledge of the training speakers associated with maximum likelihood linear regression (MLLR) matrix parameters is effectively described in terms of the latent variable models. The TSM provides various sources of information such as the correlation information, the prior distribution, and the prior knowledge of the regression parameters that are very useful for rapid adaptation. The quasi-Bayes (QB) estimation algorithm is formulated to incrementally update the hyperparameters of the TSM and regression matrices simultaneously. Experimental results showed that the proposed TSM approach is better than that of the conventional quasi-Bayes linear regression (QBLR) algorithm for a small amount of adaptation data.

Background: The number of glomerulus has been considered one of the etiologic factors especially for focal segmental glomerulosclerosis. However, glomeruli are too many to calculate them correctly. Although the fractionator method has became convinced, in which they used selected sections, not whole kidney sections, with same intervals, it is also very hard to get good results. Because it is still very time-consuming and laborous work which leads to make big observers' biases. Methods and Materials: We designed the index for glomerular number to estimate the tendency of increase or decrease of the number of it in different kidneys and which was evaluated by other conventional methods including fractionator method. Index was based upon the theory by Nyengaard; "the number of glomerulus correlates with the weight of kidney, which is positively correlated with body weight". Calculating formula is the number of glomeruli/surface areas of cortices, which contain calculacted glomeruli multiplies by kidney weight/body weight. Results: We applied this index to kidneys of FGSKist mouse and those of RFM/Nga mouse. The former is spontaneous glomerulosclerosis model with heavy protein uria and renal faille and the latter is the mother side of FGS/Kist mouse but has no glomerular disease or protein aria. The number of glomerulus of FGS/Kist mouse was decreased by 30% to those of RFM/Nga mouse. Conclusion: This index was useful and reliable for estimating the relative glomerular number between two groups.

Multiple lines of evidence link elevated blood pressure with diabetes mellitus. Specifically, it has been proposed that resistance to insulin-stimulated glucose uptake and hyperinsulinemia may play a central role in the cause and clinical course of hypertension. In diabetes mellitus, insulin resistance and/or hyperinsulinemia is an common finding and it is interesting whether the hyperinsulinemia may play a signigicant role in hypertension with DM in the same way as in essential hypertension without diabetes mellitus. The object of this study was to compare insulin and c-peptide levels between age, sex, and obesity matched two groups(DM with DM without hypertension). Method The study group consisted of 55 male diabetes mellitus patients, aged between 45-55 (years). Patients with obesity (body mass index · 30 ㎏/m2), renal disease (proteinuria · 300 ㎎/24hr urine), and secondary hypertension were excluded. Insulin and c-peptide were measured in overnight fasting state and after oral administration of glucose(75 gm). In the fasting, venous plasma glucose levels were similar in the hypertensive and control group(132 ±7 ㎎/dl vs 135 ±8 ㎎/dl). In the fasting, venous plasma insulin levels were higher in the hypertensive than in the control group (10.9 ±5.3 μIU/ml vs 5.5 ±3.9 μIU/ml, p = 0.0001). After loading with 75 gm glucose, venous plasma insulin level seems to be higher in the hypertensive patients than in the control patients, but the difference was not signigicant statistically (27.2 ±17.5 μIU/ml vs 19.9 ±18.9 μIU/ml, p = 0.1297). The mean insulin concentration of the essential hypertensive patients with diabetes mellitus was twice that of the normotensive patients with diabetes mellitus. In control group, there was a direct relations between insulin level and c-peptide, in both fasting state (R = 0.617, p = 0.0001) and glucose-loaded state (R = 0.531, p = 0.001). But in hypertensive group, there was no relations between insulin level and c-peptide, in both fasting state (R = 0.257, p = 0.2738) and glucose-loaded state (R = 0.307, p = 0.1885).

Feasibility Study on the Utilization of Mixed Oxide Fuel in Korean 900MWe PWR Core Through Conceptual Core Nuclear Design and Analysis

Joo, Hyung-Kook,Kim, Young-Jin,Jung, Hyung-Guk,Sohn, Dong-Seong Korean Nuclear Society 1997 Nuclear Engineering and Technology Vol.29 No.4

The neutronic feasibility of typical Korean three-loop 900MWe class PWR core loaded with mixed oxide fuels for both annual and 18-month cycle strategies has been investigated as a means for spent fuel management. For this study, a method of determining equivalent plutonium content was developed under the equivalence concept which gives the same cycle length as uranium fuel. Optimal plutonium zoning within the MOX assembly was also designed with the aim of minimizing the peak md power. Conceptual core designs hate hen developed for equilibrium cycle with the following variations: annual and 18-month cycle, 1/3 and full MOX loading schemes, and typical and high moderation lattice. The analysis of key core physics parameters shows that in all cases considered satisfactory core designs seem to be feasible, though addition of control rod system and change in Technical Specification for soluble boron concentration are required for full MOX loading in order to meet the current design requirements.
