우유생산 농가에서는 그들 젖소의 우유를 저장하는 탱크 (bulk tank milk: BTM)로부터 채취된 샘플로부터 분석된 우유에 대한 품질관련 항목들, 즉 체세포 수 (somatic cell count: SCC), 표준 plate count (standard plate count: SPC), 사전 incubation count (preliminary incubation count: PIC) 등에 관한 정보를 정기적으로 제공 받는다. 이러한 정보는 일정기간 쌓이게 되면 우유의 품질을 유지하고 목장을 관리할 수 있는 중요한 지식 베이스가 될 수 있다. 그러나 우유 품질이나 목장의 관리상태를 평가하는 기준은 모호하고 퍼지한 용어로 많이 표현되고 있다. 즉 우유 품질을 최상급, 상급, 중간, 불량으로 표시하거나 목장의 관리상태를 아주 양호, 양호, 미흡 등으로 표시한다. 이러한 서술방식은 퍼지이론에서의 모호한 상태를 표현하는 기준과 많이 부합되고 있다. 본 연구의 목적은 BTM으로부터 추출한 샘플로부터 미생물학적 분석을 통해서 나온 결과를 이용해서 BTM의 품질과 목장의 관리상태에 대하여 추론하는 것을 목표로 하고 있다. 따라서 퍼지추론엔진에 기초하여 퍼지로직 기반의 추론방법을 개발하고 실제 데이터를 이용해서 평가하였다. 입력 데이터로는 Bulk Tank SCC, SPC, PIC, laboratory pasteurization count (LPC), non agalactiae Streptococci, Streptococci like organisms, Staphylococcus aureus등이다. 이러한 입력자료에 근거하여 BTM의 품질상태를 아주 양호, 양호, cooling문제, 청결문제, 환경적 mastitis, 환경적/청결 복합문제로 분류하고, 낙농가로부터 채취한 실제 데이터를 이용하여 추론하였다. 본 퍼지 추론 결과는 낙농생산자, 컨설턴트, 수의사 등 관련 종사자들에게 의사결정을 위한 참고자료로서 활용이 가능하다.

Objectives: The objective of this study was to investigate the presence of oral lesions in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in a descriptive cross-sectional study, and to establish their presence according to levels of CD4+ cells (including the CD4+/CD8+ cell ratio). Materials and Methods: A total of 75 patients infected with HIV were included. Oral lesions were observed and classified using World Health Organization classification guidelines. Potential correlations between the presence and severity of oral lesions and CD4+ cells, including the CD4+/CD8+ cell ratio, were studied. Results: The most frequent oral lesion detected was oral pseudomembranous candidiasis (80.0%), followed by periodontal disease (40.0%), herpetic lesions (16.0%), hairy leukoplakia (16.0%), gingivitis (20.0%), oral ulceration (12.0%), Kaposi's sarcoma (8.0%), and non-Hodgkin's lymphoma (4.0%). The CD4+ count was <$200cells/mm^3$ in 45 cases (60.0%), between $200-500cells/mm^3$ in 18 cases (24.0%), and >$500cells/mm^3$ in 12 cases (16.0%). The mean CD4+ count was $182.18cells/mm^3$. The mean ratio of CD4+/CD8+ cells was 0.26. All patients showed at least one oral manifestation. Conclusion: There was no correlation between the CD4+/CD8+ cell ratio and the presence of oral lesions. The severity of the lesions was more pronounced when the CD4+ cell count was less than $200cells/mm^3$.

An altitude chamber, also known as a hypobaric chamber, is a device used during aerospace or high terrestrial altitude research or training to simulate the effects of high altitude on the human body. Although data from altitude chamber researches using experimental animals have been accumulated, studies in the humans exposed to hypobaric conditions are seldomly reported. Despite the importance of altitude chamber flight training in the field of aviation physiology, the hematological analysis of post-flight physiological changes has rarely been performed. The aims of the present study were to investigate the alterations in blood components during altitude chamber flight and to determine whether the differences between pre- and post-flight values are significant. Sixty experienced pilots in the Republic of Korea Air Force were enrolled in the altitude chamber flight training. Venous blood samples were obtained before and immediately after the flight. Compared with the pre-flight values($6.32{\times}10^3/mm^3$, $5.02{\times}10^6/mm^3$, 15.61 g/dL, respectively), white blood cell count, red blood cell count and hemoglobin level were significantly increased after the flight($6.77{\times}10^3/mm^3$, $5.44{\times}10^6/mm^3$, 16.26 g/dL; p=0.006, p=0.012, p<0.001, respectively). These alterations may be attributable to the exposure to hypobaric hypoxia, 100% oxygen supply for denitrogenation, considerable rise and fall in altitude and psychophysical stress due to these factors. In further studies, experimental groups and methods should be individualized to ensure objectivity and diversification. In addition, multiple time-frame analyses regarding the changing pattern of each blood component are also required to elucidate the physiological process for adapting to the high terrestrial altitude exposure.

본 논문에서 제 2세대 및 2.5세대 유럽 이동통신 표준인 GSM/GPRS에서 사용하는 MLSE 등화기의 하드웨어/소프트웨어 통합 설계를 제시한다. 이를 위해 Viterbi 알고리즘을 기본으로 하는 상관 방식(correlation)의 MLSE 기법 적응 등화기에 대한 알고리즘을 분석하고, TI사의 TMS320C5x 시뮬레이터를 사용하여 등화기의 연산량을 추정하였으며, 삼성의 0.5㎛ standard cell library (STD80)를 이용한 로직합성을 통해 하드웨어 크기를 추정하였다. 이를 기반으로 연산 요구량이 많은 블록에 대해 전용의 하드웨어로 구현함으로써 DSP의 연산 부담을 줄일 수 있다. 또한 연산 요구량이 적은 나머지 블록은 DSP로 설계하여 비교적 간단한 시스템 설계 방법을 결정할 수 있다. 이러한 설계방법을 이용하여 등화기의 효율적인 하드웨어/소프트웨어 통합 설계를 제안한다.

Bronchoalveolar lavage had been done as the treatment of some diseases such as alveolar proteinsois, bronchiectasis, and severe asthma to remove excessive secretion or mucus. But in the recent decade it has been done as a diagnostic method and a tool to understand and evaluate the pathophysiology of diffuse interstitial lung diseases such as sarcoidosis, pneumoconiosis and hypersensitivity pneumonitis. To analyse the bronchoalveolar fluid, it might be useful to have a standard reference (especially cell counts and differetial count of the cells from bronchoalveolar lavage fluid) of normal person. But it is difficult to study the normal volunteers. We investgated the bronchoalveolar lavage fluid of 48 patients (28 nonsmokers, 20 smokers) who visited Severance Hospital because of minor pulmonary symptoms such as cough and sputum. They did neither complain of dyspnea nor cyanosis, and had normal or unilateral minor lesion on physical examination and chest X-ray. We analysed the recovery rate, viability, total cell count and differential count of the cells in fluid obtained by bronchoalveolar lavage. The following results were obtained: 1) Age ranged from 17 to 72 years-old with the mean age of 36.7; there was no difference of age between the nonsmoker and the smoker gorup. Male to female ratio was 2.43:1 for total group, 1.15:1 for nonsmokers, and 19:1 for smokers. 2) The diagnoses of the patients were undetermined in 41.9%, healed pulmonary tuberculosis in 37.5%, laryngitis or pharyngitis in 10.4% and others in 10.4%. 3) Total cell number of the recovered fluid by bronchoalveolar lavage was significantly higher in male[$9.6{\pm}6.2({\times}10^6)$] than in female[$5.1{\pm}3.0({\times}10^6)$](p<0.05), and there was no significant difference in the total cell number between the smokers and nonsmokers [$9.3{\pm}5.8({\times}10^6)$ vs $7.5{\pm}5.8({\times}10^6)$]. 4) The differential count of the cells from bronchoalveolar lavage fluid had no difference between the nonsmokers and the smokers. 5) There was no correlation between the total cell count and smoking or age. 6) In the smoker group, there was no correlation between the amount of smoking and the total cell count of the bronchoalveolar fluid. In conclusion, it should be careful to regard the patients with symptoms or minor radiologic abnormalities as a control group in bronchoalveolar lavage study and further study of cell analysis in bronchoalveolar lavage will be needed between smoker and nonsmoker in the male and female healthy people.
