The objectives of this study were to investigate soil chemical characteristics for forest rehabilitation and suggest management in abandoned coal mine areas in Hwasun-gun, South Jeolla Province. Total study sites were 8 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, Avail. $P_2O_5$, and CEC. Average soil pH was 5.8 (4.7~6.4). Average contents of TOC, total-N and C/N ratio were 1.1% (0.2~2.0%), 0.08% (0.02~0.13%) and 15.0 (7.9~31.4), respectively. Average Avail. $P_2O_5$ was $8.3mg\;kg^{-1}$ (2.7~15.0) and Average CEC was $13.7cmol_c\;kg^{-1}$ ($9.9{\sim}18.5cmol_c\;kg^{-1}$). Soil pH was decreased according to elapsed time from forest rehabilitation, while TOC, total N and CEC were increased. Av. $P_2O_5$ did not show any relationship with elapsed time. Soil pH was stable comparing with general forest soil in South Jeolla Province (5.1), while contents of TOC and total N were lower than general forest soil in South Jeolla Province (4.9% and 0.18%, respectively). Therefore, sustainable managements such as fertilization for TOC and total N are necessary for good rooting and growth of vegetation.

We inestigated the reproductive cycle with ovarian development of Chlamys farreri by histological observations, and seasonal changes in biochemical components of the adductor muscle, digestive diverticula and ovary were studied by biochemical analysis. The reproductive cycle of this species can be classified into five successive stages: early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (June to August) and spent/inactive stage (August to January). According to ANOVA test, there were significant differences (p<0.05) in total protein, total lipid and glycogen contents among months for all of the adductor muscle, digestive diverticula and ovary. Total protein contents in ovary and digestive diverticula showed significant changes(ANOVA, p<0.05) during the study period, while that in the adductor muscle did not. Total protein content was highest in the adductor muscle, followed by ovary, and lowest in digestive diverticula. There was no correlation in total protein content between the adductor muscle and digestive diverticula (p=0.220). But strong positive correlation was found between adductor muscle and ovary (r=0.450, p=0.013). ANOVA showed that there were significant differences in total lipid and glycogen contents among months for all of the adductor muscle, ovary, and digestive diverticula (p<0.05). The monthly changes in total lipid content were highly variable in ovary and digestive gland. High contents of total lipid were foung during April and May-June in ovary, while March and June-July in digestive diverticula. There was a strong negative correlation in total lipid content between ovary and digestive diverticula (r=- 0.397, p=0.030). Unlike total protein of total lipid, glycogen content in the adductor muscle was most dynamic. It showed more than 36-fold changes in the adductor muscle (at most 3-fold change in ovary) during the study period. Glycogen content was higher during May-July in the adductor muscle, While it was higher in March and august in digestive diverticula. There was a strong negative correlation in glycogen content between the adductor muscle and digestive diverticula (r=-0.584, p=0.001).

This study was performed to compare nutrient intake, bone density, total cholesterol and blood glucose in women who lived in Taegu city. The number of subjects participated in the study was 89 and they were classified into 3 groups by age. 30.3% of the subject were in their 20-34 years of age, 37.1% were in their 35～49 years of age and 32.6% were above fifty. A dietary record method was used to assess the nutritional intake of subjects. Anthropometric measurement such as body weight, height and WHR, and blood pressure, blood glucose, cholesterol and BMD were measured. The results were as follows, mean weight, WHR, SBP, and blood glucose and total cholesterol of the subjects above 50 years old were significantly higher than those of 20-49 years of age(p<0.05). Mean bone density in calcaneus of subjects aged above fifty was lower than those of under 49 years of age(p<0.05). Weight, BMI, waist circumference, WHR and SBP were positively correlated with age(p<0.01). WHR and body fat were positively correlated with BMI(p<0.01). Waist circumference was positively correlated with SBP(p<0.01). Bone mineral density was negatively correlated with age and SBP(p<0.01). Also BMD was positively correlated with weight(p<0.05). Energy intakes was positively correlated with bone mineral density(p<0.05). Fat intakes was negatively correlated with SBP and blood glucose(p<0.05). Calcium intakes was negatively correlated with SBP(p<0.05). Ca/P ratio was negatively correlated with age(p<0.05) and WHR(p<0.01). Zinc intakes was negatively correlated with SBP and blood glucose(p<0.05). From the findings, it is suggested that the women after menopause keep the optimum body weight and good eating habits. Especially intake of good quality protein, calcium and carbohydrate seemed to be important.

The effects of the nonionic surfactant Tween 80 and a mixture of fibrolytic enzymes on total tract digestion, in situ disappearance (ISD) and ruminal fermentation characteristics of orchardgrass hay and barley grain were investigated in a 4${\times}$4 Latin square experiment with 4 non-lactating Holstein cows and 4 diets in 4 periods. Cows were offered a total mixed ration of 50% rolled barley grain and 50% orchardgrass hay treated with either 1) water (control), 2) 0.2% (vol/wt) Tween 80, 3) 0.2% (vol/wt) hydrolytic enzyme, or 4) 0.2% hydrolytic enzyme plus 0.2% Tween 80. Total tract digestibility coefficients of DM, nitrogen, NDF and ADF were not affected (p>0.05) by dietary treatment. Compared to the control, the rate of ISD of DM from orchardgrass hay was faster (p<0.05) in cows receiving diets treated with the enzyme alone or with enzyme plus Tween 80 (0.06/h vs. 0.076 and 0.069/h). The rate of digestion was lower (p<0.05) as compared to control when barley grain was treated with these additives. Ruminal fluid pH and concentrations of total VFA, acetate, isobutyrate and butyrate were not affected (p>0.05) by treatments. Cows that consumed diets treated with enzyme plus Tween 80 had higher (p<0.05) ruminal concentrations of propionate and isovalerate, and lower (p<0.05) acetate:propionate ratios. Compared to the control, microbial protein synthesis tended (p = 0.13) to increase with the addition of enzyme to the diet while nonammonia nitrogen flow to the duodenum increased (p<0.05) with both enzyme and Tween 80 treatments. The study indicated that fibrolytic enzymes alone or in combination with Tween 80 could enhance ISD of orchardgrass hay and ruminal concentrations of propionate, valerate and iso-valerate, but do not affect total tract digestibility.

A total of 374 Pythium isolates were isolated and identified from the rhizosphere soils of maize plants grown in 100 different agricultural fields in nine provinces at El-Minia Governorate, Egypt. Five Pythium spp. of P. deliense, P. graminicola, P. irregulare, P. oligandrum and P. splendens were obtained P. deliense and P. oligandrum were predominant in all of the locations with 48.1% and 41.4% of total counts, respectively. P. graminicola, P. irregulare and P. splendens were not isolated in 4, 2 and 4 provinces out of 9 provinces with 5.3%, 3.5%, and 1.6% of isolation percentage from total counts, respectively. Number of Pythium isolates in each were 34, 31, 34, 33, 34, 96, 37, 37 and 38 out of 374, for locations of El-Edwa, Maghagha, Beni-Mazar, Matai, Samalout, El-Minia city, Abou-Querquas, Mallawi and Der Mawas, respectively. Pre- and post-emergence pathogenicity tests indicated that only P. deliense was highly pathogenic to germinating grains and seedlings of maize whereas P. oligandrum was non-pathogenic.

This study evaluated the feasibility of recovering and recycling nitrogen (N) and phosphorus (P) from livestock excreta as struvite ($MgNH_4PO_4{\cdot}6H_2O$) in South Korea. Our experimental results showed that struvite precipitation was a very effective way to recover N and P from livestock excreta. Moreover, our study demonstrated that struvite precipitates from livestock excreta (SPL) contain higher concentrations of N, P, and magnesium (Mg) as compared to compost and liquid manure from livestock excreta. In addition, although SPL contain high concentrations of copper (Cu) and zinc (Zn), they meet the fertilizer criteria for concentrations of heavy metals. In South Korea, SPL cannot currently be used as a fertilizer due to legal constraints. Legal permission for SPL use would offer greater choice in livestock excreta management. In conclusion, recovery and recycling of N and P from livestock excreta as struvite can be an effective tool for managing nutrients in livestock excreta.

The purpose of this study was to estimate the intake of individual fatty acid and eventually to contribute to the establishment of dietary guidelines and recommendations of fatty acids for the Koreans. The subjects consisted of female college students aged 20 to 29 years old. Their dietary intake was assessed twice. in summer and in winter, by means of a 24-hour dietary recall method. Food models and other measuring tools were also used. Concentrations of serm total triglyceride, total cholesterol and HDL-& LDL-cholesterol were measured. The subjects consumed 12.3g of polyunsaturated fatty acids, 14.3g of monounsaturated fatty acids and 14.99g of saturated fatty acids per day The ratios of polyunsaturated/saturated fatty acids( P/S) and polyunsaturatedimonounsaturatedi saturated fatty acids (P/M/S) taken by the subjects were 0.8/1.0 and 0.8/l.0/l.0, respectively. The ratio of w61w3 fatty acids was found to be 8.3/l.0. All of these values seem to fall in the desirable range. The percentages of total calorie from carbohydrate. fat and protein were 59.4%, 23.4% and 17.2%, respectively. The concentrations of serum total triglyceride, total cholesterol. HDL-cholesterol and LDL-cholesterol were 59.3ms/dl, 192.7mg/dl, and 59.0mg/dl, and 121.9mg/dl., respectively.
