Corrosion loss of the shell plates of the steel vessels are measured and analyzed on the thirty cargo vessels and fifteen lumber carriers of which nationality belong to Korea. Thickness of the shell plates were determined at the every observed points set along the fore and aft line and perpendicular to it, by use of the ultrasonic thickness meter. Difference of the thickness between the original and the determined shell plates are given as the corrosion loss at the present age. The results obtained are summarized as follows: 1. On the cargo vessels, (1) The total mean of the corrosion loss is greatest at the light waterline, in every age class of the vessels. (2) The total mean of the corrosion loss on the fore and aft line shows little difference, even though it is slightly greater at the fore part, in every age class of the vessels. (3) Corrosion loss along the perpendicular line grows greater in the order of freeboard, load waterline, upper bilge line and light waterline, within the 16 of the age of the observed vessels. Its order varies to freeboard, upper bilge line, load waterline and light waterline in the age of 35. Corrosion loss at the light waterline and load waterline, in the age of 35, shows 3 times of it at the freeboard, and it at the upper bildge line shows twice of it at the freeboard. The fact significates the corrosion grows rapidly around the waterline. 2. On the lumber carriers, (1) The total mean of the corrosion loss is greatest at the upper bilge line, in the every age class of the vessels. (2) Total mean of the corrosion loss on the fore and aft line shows little difference, even though it is slightly greater at the fore part, in every age class of the vessels. (3) Corrosion loss along the perpendicular line is least at the freeboard and greatest at the upper bilge line, and its value at the upper bilge line shows twice of it at the freeboard. 3. The total mean of the corrosion loss of the lumber carriers shows almost twice of the cargo vessels.

On-line ADR is to use means of settling disputes online to settle disputes happened on-line or off-line. It gave important opportunity for engaging in a commercial transaction to small group or individual. If it uses judiciary proceeding, it will cost too much, complicate and take considerable time. So, because of these reasons, OECD even encourage on-line ADR as a mean for relieving consumer's damage actively on e-commerce. Korea is also trying to introduce on-line ADR partially or completely in Korea Consumer Agency, The National IT Industry Promotion Agency, The Korean Commercial Arbitration Board. However, Korea's on-line ADR is more insufficient than advanced country's. Nevertheless, because on-line needs to introduce, this study suggests the problem and plan centering the type and the present condition of on-line ADR.

In this study, a position control characteristics of pneumatic cylinder with transmission line is analyzed. Dynamic characteristics of transmission line using compressible fluid is changed by the flowing stiles of the fluid the diameter and the length of the line. But, the effect of the change of dynamic characteristics of transmission line by the flowing states on the position control characteristics can be neglected because of the friction force of the pneumatic cylinder. So, We assume that the position control characteristics is affected by the diameter and length of the transmission line. The experimental results according to the change of parameter of the transmission line show that the relation between the parameter of the transmission line and the position control characteristics of pneumatic cylinder driving system with the transmission line.

In the present study, growth performances of the offspring from selected brood line were compared to those of the offspring from non-selected brood line of red sea bream. Offspring groups were mass produced separately from two brood lines, selected and non-selected Korean strain. Selected brood line have been selected by fish size for four generations (upper 5∼30% per generation) and non-selected brood line is the second generation of wild population at south sea in Korea. There's no significant difference in body length between offspring from selected and non-selected brood line during early growing stage (until 96-days old). However, offspring from selected brood line had superior body weight growth than offspring from non-selected brood line. At sea cages rearing trials with communal stocking, Offspring from selected brood line showed significantly better performance in body weight, body length, weight gain, specific growth rate and feed consumption (but not in feed conversion ratio) than offspring from non-selected brood line. At 24 months old, offspring from selected brood line grew faster 1.10 times in body length and 1.41 times in body weight than offspring from non selected brood line. The response to selection when compared to a non-selected line is on average of 10% in weight per generation at 24 months old.

Improvement of orthognathic surgical techniques make it possible to design esthetic surgical correction for total esthetic face. In order to find the esthetic line which guide esthetic surgical correction in patients of orthognathic surgery, cephalometric soft tissue analysis of esthetic faces were performed. In esthetic Korean young adults, 25 males and 25 females who were within 1 S.D. of E-line, ANB, P/A facial height ratio, were analyzed in natural position keeping their face eye level. 1. Sn position is constant in males and females. The Sn-N'-N' Vertical plane angle is $5.3^{\circ}$ in both sexes. Sn is positioned in front of 5 mm in female 7 mm in male from the N' vertical plane. 2. The Sn-Ls line make constant angle to horizontal plane with $72.5^{\circ}$ in both sexes, which is called "upper esthetic line". The Ls-Pg' line makes constant angle to $72.4^{\circ}$ (range $72.2^{\circ}$ in female to $72.6^{\circ}$ in male), which is called "lower esthetic line". 3. When inter-esthetic line angle (the Sn-Ls line to Ls-Pg' line) has $144.9^{\circ}$, lower third face has esthetic upper and lower lip. 4. In treatment planning, Sn is first corrected in proper position, and then upper and lower esthetic line are established with the angle of 144.9. The maxilla is moved to tangent Ls to the upper esthetic line, and mandible is moved to tangent Li and Pg' to the lower esthetic line, according to the "y"-shaped esthetic lines, then lower third face showes esthetics.

The characteristics of Doppler shifts in a quiet region of the Sun are investigated by comparing between the $H{\alpha}$ line and the Caii infrared line at 854.2 nm. A small area of $16^{\prime\prime}{\times}40^{\prime\prime}$ was observed for about half an hour with the Fast Imaging Solar Spectrograph (FISS) of the 1.6 meter New Solar Telescope (NST) at Big Bear Solar Observatory. The observed area contains a network region and an internetwork region, and identified in the network region are $H{\alpha}$ fibrils, Caii fibrils and bright points. We infer the Doppler velocity from each line profile at a point with the lambdameter method as a function of half wavelength separation ${\Delta}{\lambda}$. It is confirmed that the bisector of the spatially-averaged Caii line profile has an inverse C-shape of with a significant peak redshift of +1.8 km/s. In contrast, the bisector of the spatially-averaged $H{\alpha}$ line profile has a different shape; it is almost vertically straight or, if not, has a C-shape with a small peak blueshift of -0.5 km/s. In both the lines, the bisectors of bright network points are much different from those of other features in that they are significantly redshifted not only at the line centers, but also at the wings. We also find that the spatio-temporal fluctuation of Doppler shift inferred from the Caii line is correlated with those of the $H{\alpha}$ line. The strongest correlation occurs in the internework region, and when the inner wings rather than the line centers are used to determine Doppler shift. In this region, the RMS value of Doppler shift fluctuation is the largest at the line center, and monotonically decreases with ${\Delta}{\lambda}$. We discuss the physical implications of our results on the formation of the $H{\alpha}$ line and Caii 854.2 nm line in the quiet region chromosphere.

Compared to off-line, on-line word-of-mouth has fast dissemination speed and extensive effects based on interactive features. Moreover, in the age of Web 2.0, on-line media has made consumers evolve from simple purchasers to producers, who intervene into product manufacturing through on-line WOM. According to this, this study is conducted to clarify how consumer's prosumer propensity affects WOM in detail when purchasing fashion products on-line through website interactivity and perceived usefulness of WOM. The results are as follows. 1. Consumer's prosumer propensity is classified in four dimensions: the propensity to participate, the propensity to relate, the propensity to amuse and the propensity to create. 2. The sample has shown low prosumer propensity overall, and there were no gender differences. 3. Testing structural equation model, it was clarified that the higher the consumer's prosumer propensity, the higher the consumer's evaluation of website interactivity and thus the greater the WOM effect through its perception of usefulness. 4. There were some differences in the path of structural equation model according to consumer's prosumer propensity. From the results, it can be concluded that consumer's prosumer propensity is a key factor in the on-line WOM. Therefore fashion businesses should actively utilize consumer's prosumer propensity to apply their opinion in the product planning stage or use it as the means of company-friendly viral marketing.

본 연구는 돼지 체세포의 clonal cell lines을 효율적으로 확립할 수 있는 배양방법을 제시하기 위하여 실시하였다. 50일령의 돼지태아로부터 섬유아세포를 회수하여 2회 계대배양 후 단일 세포를 96-well plate와 4-well dish에서 배양하여 배양액내의 FBS농도(10, 30, 50%), 첨가제(catalase, $\beta$-mercaptoethanol; BME), 세포의 크기(<16, 16~20, 20<) 및 형태(smooth, rough)에 따른 cell line 확립 효율을 검토하였다. FBS 농도에 따른 clonal line 확립 효율과 PD를 검토한 결과, 효율에 있어서 30% FBS 처리구(5.1%)가 10%(0.3%) 및 50%처리구(2.1%)보다 비교적 높게 나타났으나 유의적 차이는 없었으며, PD의 경우는 10, 30, 50%처리구에서 각각 36.7, 29.4, 26.3 시간으로 FBS 농도가 증가할수록 PD 시간이 유의적으로 짧아졌다(p<0.05). 배양액 첨가제에 있어서 BME 가시 무처리구나 catalase 첨가시보다 유의적으로 높은 효율을 보였으며(11.4%, 3.2%, 3.2%; p<0.05), PD 시간은 짧게 나타났다(23.6, 25.5, 28.1; p<0.05). 그러나 catalase는 cell line 확립 효율에 영향을 미치지 않는 것으로 나타났다. 세포의 크기에 따른 cell line 확립효율은 5.2~8.2%로 크기에 따른 차이는 보이지 않았으며, PD 또한 23.7~27.9 시간으로 세포 크기에 따른 차이는 없었다. 세포의 형태에 따른 세포의 부착율은 smooth(55.8%)구가 rough(73.0%)구보다 유의적으로 낮게 나타났으나(p<0.05), clonal line 확립 효율(7.7%n vs. 6.6%) 및 PD(23.5h vs. 24.0h)에서는 차이가 없었다. 본 연구의 결과, 세포의 형태에 따른 cell line 확립 효율은 큰 차이가 없었으나, 세포 배양액내에 30% FBS와 BME의 첨가로 clonal cell line 확립 효율을 향상시킬 수 있음을 확인할 수 있었다. 또한 cell line 확립 효율이 높아질수록 PD 시간이 짧아지는 경향을 볼 수 있었다.
