Gastric small cell carcinoma(SCC) is defined as poorly-differentiated neuroendocrine tumor of the stomach, and their morphologic and biologic features arc similar to those of the lung. It is known that this tumor has poor prognosis even in early pathologic stage, It acounts for only 3% of all gastrointestinal SCC. that has been reported only 33 cases outside and 6 cases inside of the comitiy. Most of these reports are related to advanced gastric SCC. as pathologic stage IIIb or IV. This report describes a case of early gastric SCC. pathologic stage Ib.

유동층내 설치된 수평관의 마모 특성

한근희,박영성,류정인 대전대학교 산업기술연구소 1998 산업기술연구소 論文集 Vol.9 No.2

유동층내에 설치된 수평관에 대한 마모실험을 수행하였다. 유동층 연소로의 크기는 단면적 0.15×0.2m이며 높이는 1m에 해당된다. 유동층내 유동물질로는 모래와 무연탄회재를 사용하였으며 충진층의 높이는 0.45m를 적용하였다. 마모실험용 시편은 아크릴 관이 사용되었으며 위치는 수직방향으로 15, 30, 45cm 위치에 세 개씩 그리고 60cm 위치에 1개를 설치하였다. 유동화속도, 수직높이, 층물질 종류에 따른 마모속도와 관의 원주방향에 대한 마모특성을 고찰하였다. 실험결과 마모속도는 유동화속도와 관의 수직높이가 증가할수록 늘어남을 보였으며, 시계방향으로 4∼8시간, 특히 5∼7시간 방향으로 커다란 마모율을 나타냈다. The erosion characteristics of horizontal tubes immersed in a fluidized bed cold mode combustor were investigated. The combustor has a cross sectional area of 0.15×0.2m and a height of 1m. The anthracite ash and river sand were used as a bed material. The static bed height was 0.45m. The wear specimens were made of acrylic tube. Test tubes were located inside the bed with three tubes in a low at 15, 30, 45cm and with a single tube at 60cm above distributor plate, respectively. The test was performed to investigate the effect of fluidization velocity, distance above distributor plate on the erosion rate, and the erosion trend of tube surface with radial direction. The result shows that the erosion rate increases with fluidization velocity, with distance above the distributor plate. The trend with radial direction shows severe erosion at the 4-8 o'clock clockwise compare to other area, especially 5 and 7 o'clock clockwise.

The incineration characteristics of sludge sample were investigated in a fluidized bed incinerator(φ 0.2m, 3.0m height). The sewage sludge with heating value of 2480kcal/kg, and 22% moisture content was used as sludge sample. The characteristics of sludge incineration in terms of combustion efficiency, axial temperature profile and heavy metal analysis of sludge and ash were studied. The combustion efficiencies were found to be no less than 99%, which indicates that the fluidized bed incinerator can be very effectively applied to sewage sludges. It was also found that the heavy metal components were remained in the sludge ash after incineration due to the relatively low combustion temperature of the fluidized bed incinerator.

The purpose of this study was organized to understand statistical power analysis for physical educators. There were six factors summarized as following: 1. The discrepancy between what is hypothesized and what is true: the larger the discrepancy, the lower β. The magnitude of this discrepancy is simply a fact of life; the experimenter has no control over it. 2. Sample size: the larger sample size, the lower β. This is the most important of all factors in controlling Type II error. The experimenter can choose the size we wants without having an adverse effect on other important considerations, and it is relatively easy to manipulate. 3. The standard deviation of the variable: the smaller δ, he lower β. The standard deviation can be reduced somewhat by improving the reliability of the measure, although usually the return is small for the effort expended. 4. Relation between samples (more than one mean): dependent samples can lower β. Choosing the dependent-samples design may have better potential for reducing β when comparing two (or more) means. In general, the higher the correlation induced by pairing, the stronger the effect on β. However, there are several problems with this design that do not characterize the independent-sample design. 5. The level of significance: the larger the value of α, the lower β. Although it would be possible to alter the choice of a in order to gain a desired value for β, it is a poor idea. α ought to be decided on its own merits and other means used to control β. The inverse relationship between α and β does remind us, however, of the danger of choosing an unnecessarily small value for α. 6. The choice of HA: β is smaller for a one-tailed test that for a two-tailed test. Again, ?? is under control of the experimenter, but its choice ought to flow from the logic of the study, not from the desire to control β.

權泳徹,尹在根 진주산업대학교 1979 論文集 Vol.17 No.-

海松 1-1苗를 生産하는데 보다 더 效果的인 方法을 摸索하고져 本 大學의 苗圃場에서 海松 1年生苗를 植栽密度別로 床替하여 生長狀態를 試驗한 結果를 要約하면 다음과 같다. 1. 植栽密度가 낮은 C區, D區 및 E區는 植栽密度가 높은 A區와 B區보다 生育空間이 比較的 넓어서 苗高生長이 좋았다. 2. 根元徑生長도 植栽密度가 낮은 C區, D區 및 E區가 좋았다. 3. 各區 모두 僅少한 枯死率을 나타내었으나, 植栽密度와는 關係가 없었다. 4. 海松 2年生苗의 養苗는 合格苗의 得苗比率이 높은 C區로 床替하는 것이 1年生苗의 損失이 적고 床替하는 勞動力도 節約된다고 생각된다. These studies were carried out know the effective way in order to produce 1-1 Black pine (Pinus thunber gii Parlatore) seedlings, and therefore they were transplanted as each planting density in this college's forestry seedbed and were investigated the growth by planting density. The results are summarized as follows. 1. In the case of C. plot, D. plot and E. plot of low planting density the top height growth was shown better than A. plot and B. polt of high planting density owing to have large width. 2. The root caliper growth was also showed to be good in C. plot, D. plot and E. plot of low planting density. 3. In the case of each plot, there was a similar ratio of withering and death and it was related to planting density. 4. Based on the above-mentiond results, it was concluded that 1-1 Black pine seedling should be transplanted at C. plot gainning much seedlings by standing test and for that reason the expenses and labors wre substracted by it.

This laboratory study examined the impact of free chlorine residual and pipe material on the formation of biofilm in drinking water distribution pipe surfaces. Result of heterotrophic plate counts(HPC) of the biofilm in the tap water- supplied reactor averaged 2.17×105CFU/cm2 on PVC and 2.43×105CFU/cm2 on STS 316, respectively. HPCs on the surface exposed to the tap water containing 0.2mg/L of free chlorinne residual averaged 4.24×104CFU/cm2 on PVC and 6.54×104CFU/cm2 on STS 316, respectively Average of HPC/Total direct counts in the tap water-supplied reactor ranged from 1.08%(PVC) to 1.26%(STS 316) and from 0.38%(PVC) to 0.65%(STS 316) in the reactor supplemented with disinfectant, resfectively. No correlation was observed between disinfectant addition and biofilm density. With regard to the biofilm formation, little difference existed between PVC and STS 316. Yellow and red pigmented bacteria were the dominant expressions in bulk fluid, whereas non-pigmented bacteria were found dominant in the biofilm. Pink/red pigmented bacteria were found to be facultative anaerobic, while yellow pigmented bacteria and non-pigmented bacteria were found to be obligate aerobic.

Phanerochaete chrysosporium의 액체 배양 및 Lignin Peroxidase 생산

박세근,정명선,김영관 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

This study characterizes the growth of white rot fungi Phanerochaete chrysosporium IFO 31249 and lignin peroxidase(LiP) activity in different submerged culture media. P. chrysosporium was grown in the form of pellet of various sizes from a spore inoculum under shaking liquid culture condition. While the growth of mycelia was higher under the nitrogen-sufficient culture than under the nitrogen-limited culture, ligninase activity was relatively lower. The lignin peroxidase appeared in nitrogen-limited culture and was suppressed by excess nitrogen. High level(40U/l) of lignin peroxidase activity was obtained in the growth medium containing 1.5mM veratryl alcohol, a secondary metabolite of P. chrysosporium. Lignin peroxidase production was not observed under conditions of nitrogen sufficiency or in balanced media, suggesting that control parameters could increase the activity by manipulating the secondary metabolism.

최적배치를 위한 워드모델 및 비트연산자 개발

In this paper, a new nesting method based upon the 'word representation' of parts and raw sheets is proposed to improve the performance of pixel-based nesting. In this new representation, the pixel patterns of parts and sheets are converted to proper word-sets. And all the usual nesting processes such as part allocations, de-allocations, overlap testings and etc. can be performed through the 'bit operations' between words of the parts and sheets. The proposed method shows some possibilities to overcome the shortcomings of the traditional pixel-based nesting. In addition, a new efficient gap searching method based upon the quad-tree is presented to locate proper allocation positions of the parts.
