"Chamgreen" was a domestically developed rye (Secale cereal L.) cultivar in South Korea, known for its quick heading, cold resistance, and abundant yield of forage. The heading date of cv. 'Chamgreen' averaged April 17th, which was 4 days earlier than the standard cv. 'Gogu'. In the early harvesting stage, the plant height reached an average of 119 cm, 7 cm taller than the standard cv. 'Gogu', and the number of spikes per m² was 865, slightly less than cv. 'Gogu's 897. Resistance to cold and powdery mildow remained consistent across four regions nationwide over three years, with an average rating of 0, matching cv. 'Gogu'. Lodging resistance was also rated at 2, equivalent to cv. 'Gogu'. The dry matter yield of cv. 'Chamgreen' was 9.1 tons per hectare, 15% higher than cv. 'Gogu's 7.9 tons. Although the protein content in cv. 'Chamgreen' was 13.5%, 1.6% lower than cv. 'Gogu', the total digestible nutrients (TDN) content was 5.81 tons per hectare, 20% higher than cv. 'Gogu'. Due to its strong cold resistance, cv. 'Chamgreen' allows for winter cultivation through double cropping and rotation systems in various regions across the country.

Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test, additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12 / CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, Chiljehyangbuhwan was correlated to ${\Delta}T$ (CV12 and CV3 / CV12 and CV4). In case of VRS, Chiljehyangbuhwan was not correlated to ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with ${\Delta}T$ (CV12 and CV3 / CV12 and CV4) after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan effects the abdominal temperature according primary dysmenorrhea severity.

The effect of Chlorella vulgaris (CV) on the urinary excretion of di-ortho PCB congeners (PCB-138, -153) was investigated. Sprague-Dawley rats (6-weeks-old, n=10 rats/group) were randomly divided into one control (0CV) or 2% CV (2CV) or 5% CV (5CV) or 10% CV (10CV) groups, respectively. Composition of normal and chlorella meal-based diet were made up of 30% casein, 15% cornstarch, 50% sucrose, 5% cellulose, 5% coconut oil, 3.5% mineral mixture, 1 % vitamin mixture. All rats had free access to water and diet for 4 weeks. A significant increase in both PCB 138 and 153 in urinary level was detected in CV fed groups, 540% and 167% for 2CV, 155% and 89% for 5CV, 114% and 144% for 10CV group, respectively, when compared with their controls. These findings suggest that CV may have potential to eliminate body burden levels of dioxin-like PCB compounds.

Many researchers have studied the eutectic solidification of CV Graphite Cast Iron qualitatively. However quantative studies have not been done. The type of eutectic solidification of CV Graphite Cast Iron treated with CG Alloy (Fe-Si-Mg-5Ti-Ca-Ce) was studied quantitatively through M.D.E. value (Mushy Degree of Eutectic Solidification) = $t_2/t_1)$, where $t_1$ is the difference of the eutectic solidification starting time between surface and center part of the casting sample, and $t_2$ is the time of eutectic solidification of the center part. Following results were obtained. (1) The M.D.E. value of CV graphite cast iron lies between that of spheroidal graphite and that of flake graphite cast iron but is closer to that of Flake graphite cast iron. (2) The M.D.E. value of CV graphite cast iron depends upon CV ratio. (3) The time required for eutectic solidification increases as graphite form is changed from Flake, CV. to spheroidal graphite. (4) The M.D.E. value increases as cooling rate increases.
