A fourteen-month-old intact female Poodle was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Chungnam National University. The patient was presented with history of vomiting, inappetence, ataxia, insomnia, tachypnea and convulsion for 5 days. Biochemical examination revealed BUN (254.2 mg/dl), creatinine (9.22 mg/dl) and phosphate (14 mg/dl). Epithelial cells of urinary tract, neutrophils, macrophages, a large number of gram negative and smaller number of gram positive bacteria were presented on urine test. Ultrasonographic findings show hyperechogenic kidney and indistinguishableness of renal cortex and medulla. Based on the results of examination described above, this case was diagnosed as acute renal failure with interstitial nephritis by urinary tract infection (UTI). Treatments with fluids therapy, diuretics, and peritoneal dialysis during hospitalization showed good results with no clinical signs.

워크스테이션 클러스터 환경에서 신뢰성을 제공하는 효율적인 파일 시스템

워크스테이션 클러스터상의 소프트웨어 RAID 파일 시스템이란 네트워크로 연결된 다수의 시스템들이 보유한 각 디스크를 통해 하드웨어 RAID의 기능을 소프트웨어적으로 제공하는 시스템을 의미한다. 이러한 시스템은 기존의 분산 파일 시스템에 비해 높은 성능과 신뢰성을 제공해준다. 본 논문에서는 우선 소프트웨어 RAID 파일 시스템에 대해 상세히 살펴본다. 그리고 소프트웨어 RAID 파일 시스템에 효율적인 캐슁 기법을 제안하고 기존의 캐슁 기법들과의 성능을 다양한 환경에서 비교한다. 다음으로 소프트웨어 RAID 파일 시스템에서 스트라이핑이 시스템 성능에 미치는 영향에 대해 실험을 통해 살펴본다. Software RAID file system provides the same capability which hardware RAID facilitates with multiple disk arrays maintained among the networked systems. These systems provide high performance and better reliability than the traditional distributed file systems. In this paper, the software RAID file system is discussed in detail. An efficient caching scheme is introduced and compared to other caching strategies on different settings. Simulations are conducted to evaluate the system performance effected by the stripping on the software RAID file system.

선반입에 관한 고찰

선반입(prefetching)의 기본 원리는 미래에 사용될 블록을 미리 캐쉬로 읽어 들여 디스크 접근 지연시간을 사용자로부터 가림으로서 전체 성능을 향상시키는데 있다. 이때 선반입 할 시기와 내용은 파일에 대한 접근형태에 의존하며 이에 관한 다양한 연구들이 이루어지고 있다. 이에 본 논문에서는 기존의 선반입 정책들과 파일 시스템의 참조 형태에 관해 살펴보며 선반입 정책을 평가할 수 있는 시뮬레이터를 통해 간단한 실험을 한다. 이를 통해 얻은 결과는 다음과 같다. 선반입은 주로 큰 파일들을 순차적으로 접근하게 되는 멀티미디어 시스템에 적용하는 것이 매우 효율적일 것으로 판단되며, 또한 기존의 연구에서는 미래의 접근 형태를 사용자가 알고 있다는 비현실적인 전제하에 이루어진 연구가 많았는데 사용자가 접근 형태를 모른다는 현실적인 환경에서의 연구가 시급함을 알 수 있었다.

The effects of Laminaria japonica fucoidan extract (LJFE) on the biochemical parameters of lipid-related function were investigated in liver and serum of CCl_(4)-treated rats. LJFE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 14 days. On the day 15, 3.3 ml/kg of CCl_(4) dissolved in olive oil (1:1) was injected 12 hours before anesthetization. We examined the lipid-related functions and enzyme activitys by measuring the levels of total cholesterol (TC), triglyceride (TG), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in serum. The results showed that CCl_(4) treatment increased the high values of TG, LDH and ALP decreased the low values of TC but LJFE pretreatment decreased the high values of TG, LDH and ALP to the low values, increased the TC. It was suggested that LJFE can be used as the potential candidate for the lipid-metabolism natural supplement.

This study was conducted to examine the correlation among growth development, bone mineral density, and nutrient intakes in preschool children. A total of 62 preschool children measured the anthropometric characteristics and the bone mineral density of carpus using DEXA. The questionnaires categorized to determine health status, life style, dietary behaviors, and dietary intakes were filled out by children's mothers. The average ages of the study subjects were 62.4 months in boys and 62.1 months in girls. The birth height and weight of the subjects were 50.9 ㎝ and 3.4 ㎏ in boys and 50.3 ㎝ and 3.3 ㎏ in girls, respectively. The average height, weight, % body fat, and obesity index were 111.7 ㎝, 19.6 kg, 15.0%, -2.1% in boys and 109.4 ㎝, 18.7 ㎏, 17.5%, 0.2% in girls, respectively. The bone mineral density in carpus was 0.25 g/㎠ in boys and 0.24 g/㎠ in girls. Proportions of children having regular meals were 69.0%, 94.7% and 69.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were poor appetite and lack of time for breakfast and snacks for dinner. Most of the children(52.6%) had breakfast with the whole family together, and all the children had lunch and dinner with a part of the family. Most of the children answered they had snack more than once a day, and 64.3% had an unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B₁, niacin, and vitamin C did not meet the Korean RDAs. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B₁, niacin, and vitamin C did not meet the Korean RDAs. Average bone mineral density in carpus was positively correlated to the body weight, the total body water, the lean body mass, and obesity index, respectively(p<0.01, p<0.01, p<0.01 and p<0.01). The body weight, the total body water, and the lean body mass showed the significant negative correlation with the animal iron intake(p<0.05, p<0.01 and p<0.01). The bone mineral density the distal carpus was negatively correlated to the animal protein intake and the animal iron intake(p<0.05 and p<0.05). And the bone mineral density in the ultradis carpus and the average bone mineral density in the carpus were positively correlated to the plant calcium intake(p<0.05 and p<0.05). Therefore, more systematic studies to investigate the roles of protein, iron, and calcium in growth development of preschool children were required.

In order to know the residual pattern of pesticides and predict to the degradation period until below MRL, we experimented procymidone and chlorothalodi for grape which were the most detected pesticide in grape by NAQS(National Agricultural product Quality management Service) survey. In this experiment, we sprayed those pesticides 10 days before harvest and analyzed 0, 1, 2, 3, 5, 7, 10 day sample to establish logical equation and to calculate DT_(50) Also the same day samples stored at 4℃ and 20℃, which were compared their degradation patterns. During the cultivating period, the residue amount of procymidone was changed from 1.85㎎/㎏(0day) to 0.33㎎/㎏(10days), DT_(50) was 3.5 days, and chlorothalonil was changed from 5.5 ㎎/㎏ (0 day) to 3.49 ㎎/㎏ (10 day), DT_(50) was 4.4 days. During the storage period, DT_(50) of procymidone and chlorothalonil at 49c were 10.5 and 7.6 days, and 6.3 and 6.1 days at 20℃, respectively.

원형 Cavity를 이용한 펄스형 Nb:YAG 레이저의 출력특성 및 병렬메쉬 회로의 최적화

본 연구에서는 기존의 타원형 cavity가 아닌 원형 cavity를 설계 및 제작하여 그 동작특성에 관하여 연구하였다. 그 결과 타원형 cavity 보다 다소 적은 레이저 출력 효율 2.1%를 얻었다. 원형 cavity는 타원형 cavity 보다 컴팩트하며 제작하기가 용이하고, 제작 단가가 저렴하다는 장점이 있다. 입력에너지, 입력전압 및 펄스 폭을 동일하게 했을 경우 주회로 병렬 메쉬회로수를 최적화하고자 한다. PFN 회로를 1단에서 8단까지 PSPICE로 모의시험한 전류파형과 실제 실험한 전류파형이 거의 일치하였다. 그 결과 500㎲이상의 펄스 폭에서 6단 메쉬가 최적의 병렬 메쉬라는 결론을 얻었다. In this study, we have deigned and manufactured not only a present elliptic cavity but also a circular cavity, and experimented the operational characteristics. As a result, we obtained the maximum efficiency of 2.1% that was not less than that of an elliptic cavity. A circular cavity is much more compact and is easier to be manufactured than an elliptic cavity. And it can be made at a low cost. When the input energy, input voltage, and pulse width were in the same condition, we tried to decide the optimization of the mesh number of a parallel-mesh circuit which was connected with main power supply. The PSPICE simulation waveform of PFP(Pulse Forming network) circuit ranging from 1-mesh to 8-mesh nearly corresponded with the real current waveform obtained through a practical experiment. From these experimental results, we obtained the result that 6-mesh was the optimal parallel-mesh circuit in case that the pulse width was more than 500㎲.

Overall quality in 1.5% Jeung-Pyun showed the worst of 0, 0.5, 1.0% Jeung-Pyuns(p<0.05), especially 1.0% Jeung-Pyun had relatively the best overall quality. But the sweetness, sourness, flavor, hardness, moistness were not significantly different among all Jeung- Pyuns. 0, 0.5, 1.0% Jeung-Pyuns showed the best quality of Jeung-Pyun through sensory, mechanical property. Total color difference was increased as amount of Mal-Cha(p<0.001).
