Purpose: This study is to assess the involvement of vessels in lower extremity in diabetics, using color doppler ultrasonogram. Materials and Methods: Arteries of both lower extremities were divided into 3 groups-large vessel (above-knee arteries), popliteal vessel, and small vessel(below-knee arteries) -, and evaluated using color doppler ultrasonogram in 60 diabetics. In color doppler ultrasonogram, the wave forms of all vessels were divided into 5 grades; grade I was triphasic wave form, grade II was spectral broadening form, grade III was monophasic wave form, grade IV was pulsus tardus et parvus form, grade V was absence of wave. Grade III, IV, V were grouped into vessel obstruction. We reviewed the correlationships among the degree of the peripheral vascular involvement, duration of dibetes, existence of bilaterality, types of dibetes. Results: Bilateral involvement was high in both lower extremity. Luminal stenosis, vascular calcification and vessel obstruction were high incidence in the patients over ten years of diabetic duration. Prevalence of vascular calcification and vessel obstruction were high in the small vessel of ankle level. But, insulin injection was not related to the incidence of vascular abnormality. Conclusion: Color doppler ultrasonogram seems to be useful for evaluation of peripheral vascular status, decision making for necessity of additional test, periodic follow -up tool in diabetes patients.

By evaluating the health status by Cornell Medical Index in conjunction with their academic grade, we attempted to find out whether any health condition may affect on their academic carrier. CMI health questionnaire was filled out by student and matched with one's own academic score if the previous year. Academic score was classified into 5 grades: excellent, very good, good, fair and poor. Difference in number of questions between sections was corrected by standard score method with means of 50 and standard deviation of 10. Differences in number of 'yes' answers between sections and between groups of students in each grade were statistically tested by two-way variance analysis method. On the other hand, influence of neuropsychiatric factors (section M-R) on the academic carrier was analyzed by $X^2-test$ with Fukamachi's classification. The following were the results obtained in this study: 1) Number of 'yes' answers in sections related to mood and feeling patterns (sections M-R) were appeared to be influential to academic carrier in male students, but not in female students. 2) Generally speaking, in groups of higher academic grade, number of 'yes' answers in each section was on an averege 50 or less, and in groups of lower academic grade, the number was 50 or more depending on sections. 3) Number of 'yes' answers between sections and between groups in each academic grade were significantly different both in male and female college students. 4) It was noteworthy that data obtained from CMI questionnaire might be variable subjectively by examinees with some factors at the time of administration.

Arabica coffee is classified for trading according to the New York Board of Trade(NYBOT) green coffee classification. NYBOT's grading system is based on classification derived from a defect count on a 300 g sample. In the present study, green and roasted coffees were investigated for possible correlations between the content of defective beans and sensory characteristics. Sensory evaluation was performed by expert tasters used by the Specialty Coffee Association of America(SCAA) cupping method. For green coffee, the percentage of defective beans increased. as the coffee grade decreased. Black and sour beans were not found in the NY2 grade coffee out of all natural, pulped natural, and washed coffee samples. Sour and insect damage were found in more natural coffee samples as the green coffee grade decreased. Green and broken beans were found in more washed coffee samples as the green coffee grade decreased. Flavor, clean, uniformity, aftertaste, and overall sensory characteristics were significantly different among the NY2, NY3/4 and NY4/5 grade coffee in all natural, pulped natural and washed coffee samples. The natural coffee in the NY2 sample presented the highest body characteristic. The pulped natural coffee in the NY2 sample presented the highest sweetness and balance characteristics. The washed coffee in the NY2 sample presented the highest acidity and flavor characteristics. In conclusion, the percentage of defective beans increased as sensory characteristics decreased.

The survey was conducted to investigate the relation between slaughter inspection results and the quality of cattle carcasses by inquiring animal products grading service results of Korea Institute for Animal Products Quality Evaluation (KAPE) about partial-disposed cattle carcasses after dismantling inspection. Of the 13,586 slaughtered cattle, 1,343 (9.9%) cattle heads were partially disposed from January to August, 2012 at slaughterhouses in Gwangju area, Korea. Of the 1,343 partial disposed cattle, 613 (45.6%) cattle carcasses were graded into above "Grade 1". Among partially disposed 1,171 Hanwoo heads, 613 (52.3%) cattle carcasses were graded into above "Grade 1". However, none of dairy and beef cattle carcasses were graded into above "Grade 1" out of 163 and 9 partial disposals, respectively. Of the 221 partial disposals by enteric fat necrosis, 139 carcasses were graded into above "Grade 1", and the ratio; 62.9% (P=0.001), was higher than that (50.3%) of total cattle carcass grade which is above "Grade 1". From these results, it is suggested that quality of cattle carcasses which is mainly determined by marbling might be related to the fatty lesions such as fatty liver and enteric fat necrosis.

In order to invest in overseas mineral projects, it is necessary to have a ability of technical and financial evaluation. Reserve estimation is the most important for mineral appraisal. Geostatistical evaluation of tonnage and grade promises more accurate reserve estimation than traditional methods such as polygon, inverse distance method and so on even if it has some uncertainty. Selection of a mining method and a mineral processing is also important because capex and opcosts of a mineral project is due to the selection. Mineral project is usually evaluated financially using NPV and IRR which are calculated through DCF(Discount Cash Flow). Uncertainty of a mineral project is analyzed statistically using sensitivity analysis and montecarlo simulation.

In the paper, we designed an automatic security diagnostic evaluation System(SeDES) based on a security diagnostic evaluation model(SeDEM) for an organization's security assurance. The SeDEM evaluates a security level of an organization quantitatively by a security evaluation formula which is composed of security variables and security index as applying the statistical CAEL model for evaluate risk level of banks. The SeDES has a good expandability as changing security variables according to an organization scale, characteristics and so on. And it also has a excellent usage because it inputs only numeric data got from statistical technique to security index. We can understand more a security level correctly than the existent risk assessment system because it is possible to assess quantitatively with an security grade as well as score. analysis.

본 논문은 KS의 침입도 등급 체계에 대한 통계적 타당성을 검토하였다. 각 등급의 범위는 신뢰구간에 근거하여 설정되어야 하며, 최대한 인접 등급과의 중복을 피하도록 해야 한다. 그러나 통계적 이론에 근거해 검토한 결과 KS 침입도 등급 체계에는 각 등급 사이에 간격(Gap)이 없어서 범위를 벗어나는 것은 바로 다른 바인더의 등급을 침범한다는 점을 알 수 있었다. 따라서 많은 바인더 제품들의 침입도 평균값이 규정한계 내에 있을지라도 인접한 등급과 유사한 특성을 가질 수 있다. 또한 침입도 40-60, 60-80, 80-100과 같이 등급의 범위를 모두 20으로 규정한 것은 통계적 타당성이 없다. KS 침입도 등급은 각 등급 간에 간격이 없기 때문에 생산자는 제품의 품질관리 규정을 만족하기 위하여 ASTM 체계의 제품보다 변동계수를 더 낮게 유지해야 한다. 게다가 침입도평균이 상 하한선 쪽으로 치우친다면 재료의 품질 불확실성 때문에 바인더의 1/2 또는 그 이상이 인접 바인더와 중복된 것이다. 그러므로 KS침입도 등급은 통계적으로 타당토록 바로 수정되어야 한다.
