The purpose of this study was to investigate the effects of glucuyonic acid (isolated from xylan) on the antioxidative defense systems of red gastrocnemius in rats after aerobic exercise. The glucuronic acid was isolated from xylan. Male Sprague-Dawley vats weighing 150$\pm$10 g were randomly assigned to one normal group and three exercise training groups. The exercise training groups were classified as T (glucuronic acid-free diet), TU (250mg glucuronic acid/kg bw) and 2TU (500mg glucuronic acid /kg bw) according to the level of glucuvonic acid supplementation. The rats in the normal group were confined to a cage for 4 weeks. The rats in the exercise training groups ran on a treadmill for 30 min/day, 5 days/week at a speed of 28 m/min (7% incline) for 4 weeks. Glutamate oxaloacetate transaminase (GOT) activity in the exercise training groups increased significantly compared with that of the normal group. That of the TU and 2TU groups decreased significantly compared with that of the T group. Xanthine oxidase (XOD) activity in the T group increased significantly to 74% compared with that of the normal group. That of the 2TU group decreased to 42% compared with that of the T group, thus recovering to a normal level. Superoxide dismutase (SOD) activity in the T group decreased to 32% compared with that of the normal group. That of the TU and 2TU groups increased to 28% and 34%, respectively, compared with that of the T group. Glutathione peroxidase (GSHpx) activity in the T group decreased to 16% compared with that of the normal group, but that of the TU group increased to 17% compared with that of the T group. Glutathiones transferase (GST) activity in the T group decreased to 11% compared with that of the normal group, but that of the TU and 2TU groups Increased to 28% and 31%, respectively, compared with that of the T group. The contents of thiobarbituric acid reactive substances (TBARS) in the T group increased to 81% compared with that of the normal group, but the glucuronic supplementation group recovered to the normal level. In conclusio, the effects of glucuronic acid on red gastrocnemius in rats engaged in exercise training would appear to be to reduced lipid peroxidation of tissue as an antioxidative defense mechanism.

In the Upo wetland, physico-chemical factors were observed during the period from March 2005 to December 2007 on a monthly basis. In the Upo wetland, water temperatures ranged $3.4{\sim}34.5^{\circ}C$. Conductivities were in the range of 133~806 ${\mu}S\;cm^{-1}$, which showed about 140 ${\mu}S\;cm^{-1}$ below in comparison with the precedent studies. The pH levels were between 6.7~9.1 with lower level in summertime. The dissolved oxygens were between 0.06~18.23 mg $L^{-1}$. COD ranged 4.9~20.8 mg $L^{-1}$, and showed a tendency to decrease every year. Nitrogen nutrients such as nitrate nitrogen ($NO_3-N$), ammonia nitrogen ($NH_3-N$) and total nitrogen (T-P) showed that they were generally decreased in comparison with those in the precedent studies. However the total nitrogen (T-N) is still considerably higher than the standard concentration level of eutrophication and algal blooming. Phosphate phosphorus ($PO_4-P$) and total phosphorus (T-P) were also shown as to be reduced considerably comparing with the values in the precedent studies. However, It was found out that total phosphorus (T-P) was dissolved over the criteria concentration of eutrophication. The average of TN/TP ratio was 18 in the Upo wetland, which proved that phosphorus was the limiting factor to the growth of phytoplankton in the Upo wetland. The chl-$\alpha$ was the highest in wintertime and the lowest in summertime, and especially in 2006 summer when the cyanobacterial bloom developed, it showed extremely high concentration.

This study was investigated the effort of growth and gonadal development in olive flounder, Paralichthys olivaceus exposed to PCBs Effluent Allowance Concentration, 3.0 ppb in Korea. Total length, body weight and weight gam of fish were no significant differences between two treatments (control: T.L.-110.0 mm, T.W.-9.61 g: treatment: T.L.-112.8 mm, T.W.-9.68 g), however, weight gain of fish unexposed to PCBs wat observed to increase gradually from 100 days after hatching (30 days after treatment). In the indifferentiated gonad to the juvenile stage, the differentiation of the ovary occured at 60 days after hatching (20 days after treatment) and that of the testis occured at 70 days after hatching (30 days after treatment) in two groups. In the ovary, the oogonia and ovarian lamellar appeared 130 days after hatching (50 days after treatment). The spermatogonia and resticular lobule of the testis were observed at 130 days after hatching (50 days after treatment). Testicular cyst appeared 140 days after hatching (60 days After treatment). There was no difference on the development of ovary and testis. There was no obvious difference of sex ratios. Therefore, These results considerate that PCBs have any effect for growth and gonadal development, but a little act for early growth in olive flounder.

Fashion magazine advertising is the most excellent source of information in predicting the fashion trend. It plays a pivotal role in setting a direction for the fashion trend in the upcoming season. The purpose of this study was to review by photos of the $pr{\hat{e}}t-{\acute{a}}-porter$ collection shown in LONDON, NEW YORK, MILAN, and PARIS during 2002-2006 A/W and 2003-2005 S/S seasons, being focused on such fashion items published as coat, dress, one-piece, two-pieces(jacket+skirt/pants, blouse+skirt/pants). In the results of this study, designers presented coat(n=144) chiefly, blouse+pants(n=29) were presented few during 2002-2003 A/W seasons. During 2003-2004 A/W seasons one-piece(n=156) was looking bullish, blouse+pants(n=34) were declining. Dress(n=149) was presented mostly, blouse+pants(n=17) was presented few during 2004-2005 A/W seasons. During 2005-2006 A/W seasons coat(n=180) was revived, blouse+pants(n=26) were presented lowly. Therefore designers presented coat(n=605, 28.4%) extremely much during 2002-2006 A/W seasons. Designers presented one-piece(n=109) much, jacket+pants(n=22) were presented few in 2003 S/S. In 2004 S/S seasons one-piece(n=167) was presented vastly different than jacket+pants(n=42). Also one-piece(n=152) was presented mostly, blouse+pants(n=48) was presented few in 2005 S/S seasons. During 2003-2005 S/S seasons one-piece(n=428, 28.2%) was presented most. And designers in these four world fashion centers didn't prefer blouse+pants in A/W seasons and jacket+pants in S/S seasons. Based on the above findings, it could be confirmed that the fashion items trend was almost similar among the four collections of $pr{\hat{e}}t-{\acute{a}}-porter$. The results of this study suggest that the fashion collections are the most reliable information sources for fashion product planning. Lastly, it is hoped that this study will provide for some useful basic data for domestic fashion businesses in producing fashion items.

Radioisotope renography was carried out in 564 cases consisting of 150 normal controls, 140 hypertensives, 102 hypertensive nephropathys, 62 chronic renal diseases, non-functioning kidneys. It was aimed to study which parameter of the renogram is most applicable to any definite disease of the kidney. The analytical methods adopted were; Tobe, Spencer, Krueger, Matchida and Takeuchi. In the non-functioning kidney groups, the hemograms and serum nitrogen series were also studied to evaluate the relationships between the renograms and renal anemia. The parameters were; time of maximum amplitude (Tmax), half-time of maximum amplitude ($T\frac{1}{2}$), Kac value calculated from these two parameters in Tobe's method, slopes of Band C phase, B/A and B/C values in Spencer's method, total concentration (T.C.), minute concentration (M.C.) and minute excretion (M.E.) in Krueger's method, Matchida's K value and Takeuchi's renal function Index (R.F.I.). Following were the results: 1. In general, marked differences in the patterns of the renogram were observed between the normal controls and nephropathys. In Tobe's method, each parameter showed statistically significant delay or decrease in patients with hypertensive nephropathys and chronic renal diseases. In Spencer's method, slopes of B and C phase and B/C, also showed the statistically significant decrease in patients with hypertension, hypertensive nephropathys and chronic renal diseases. In Krueger's method, M.C. and ME showed the statistically significant differences between the control and patients with hypertension, hypertensive nephropathys and chronic renal diseases, In Matchida's method, K value showed the statistically significant differences between the control and patients with hypertensive nephropathys and chronic renal diseases. 2. It appeared, therefore, that Tobe's $T\frac{1}{2}$, Kac value, Spencer's slopes of Band C phase, B/A, B/C values, Krueger's T.C., M.C., and M.E. values, Matchida's K value are useful for the differentiation of various renal diseases, however, qualitative analysis of the renogram with one or two parameters is not accurate. 3. In bilateral non-functioning kidney groups, a positive correlation between anemia and nitrogen retention was observed, although the quantitative assessment of the degree of non-functioning was impossible.

This study investigated the thoughts of undergraduate students in Seoul about the birth rites and wedding ceremony and their foods. Among 524 students who were surveyed, 299 students answered that the meaning of the first birthday rites was for special memory, followed by the child's future and family's harmonies. 248 desired birth rites to remain unchanged and 150 desired extravagance and waste to be reduced. Regarding wedding ceremony, 328 answered that changes are necessary in wedding ceremony gifts. Next, process in wedding ceremony and bridegroom's gift box should be changed, Most of the students didn't know clearly the foods of the one hundredth birthday and the first birthday; nevertheless they considered the birth rites to be necessary. Regarding wedding ceremony, half of the students knew the process and half didn't. Two hundred students answered they knew ordinarily about the foods of wedding ceremony. There were no significant differences in hometown about foods of wedding ceremony. In parent's religions, there were no differences about gifts & foods offered by the bride. The Buddhist students knew well about the birth rites' foods and considered birth rites to be necessary. The correlation of parents' work and student's major and passage rites showed that professional parents knew well about birth rites' foods but religious believers didn't know well. Students majoring in natural science were not concerned with birth rites and thought that they were unnecessary and they didn't know about wedding ceremony process and foods. Knowledge about birth rites increased with increasing number of siblings. Large families were interested in birth rites and knew well about the wedding process, wedding ceremony foods and gift & foods offered by the bride.

Bi-doped lanthanum magnetics $(La_{0.67-x}Bi_xCa_{0.33}MnO_3(x\;=\;0,\; 0.04,\; 0.1,\; 0.2))$ samples have been prepared by standard ceramic process. The crystallinity and microstructures of the samples have been investigated by x-ray diffractometry and optical microscopy, respectively. The magnetic and magnetoresistive properties of the samples have been measured by vibrating sample magnetometery and van der Pauw method, respectively, at the temperatures ranging of 100 K~300 K with applied magnetic field of 0.4~0.5 T. Good crystallinity and high Curie temperature (275 K) have been obtained for the Bi-doped samples with small dosage (x = 0.04, 0.1) even they were sintered at 120$0^{\circ}C$, which is about 20$0^{\circ}C$ lower than normal sintering temperature of 140$0^{\circ}C$. The Bi-doped samples with the small dosage showed lower relative electrical resistivity and higher magneto-resistive ratio compared to the undoped sample in the most temperatures measured. The Bi-doped samples also exhibited large magnetoresisitve ratio (maximum of 15% for x = 0.1) at room temperature even under a weak magnetic field of 0.4 T.

This technology employs a method of forming a single-ply PLUS waterproofing sheet layer comprised of applying a single-ply synthetic polymer layer on a vibrating structure (steel frame, RC) or an inclined surface by using a T joint lap-filling coil and an embedded metal coated sheet. The T - joint reinforcing lap-filling coil was used to block the ingress channel of the rainwater by applying the material in the vulnerable area where the three sides of the waterproof sheet overlapped. Conventional waterproofing techniques have a problem in that the waterproof sheet is pierced because the end portion of the waterproof sheet applied to the vertical portion is fixed by a nail, and the sealant applied to the end portion of the sheet cannot easily secure long-term waterproof durability due to the influence of the external environment. Therefore, the developed technology secured the waterproof durability against the vertical part by using the embedded metal sheet. In addition, automatic hot-air fusing is used to improve the quality of waterproof construction and point fixation method using fixed hardware. This is a technology that is not significantly restricted in the high degradation level regions of domestic waterproof construction environments in Korea such as low-temperature environment, wet floor.
