At present, the polymer-modified mortars are used as high-performance as well as multi-functional materials in the construction industry. The purpose of this study is to synthesize polymer to modify in cement mortars and make test samples to understand the resistance of carbonation. This paper deals with the effect of monomer ratio and polymer-cement ratios on the typical properties of polymer-modified mortars using Methylmethacrylate-Butyl Acrylate(MMA/BA) latexes synthesized through emulsion polymerization. From the results, we knew that the resistance for carbonation of polymer-modified mortars using Methylmethacrylate- Butyl Acrylate latexes is increased with an increase in the monomer ratio of MMA/BA and the polymer-cement ratio. the resistance for carbbaonation of polymer-modified mortars using Methylmethacrylate-Etyl Acrylate latexes is increased with an increase in the polymer-cement ratio. The most resistance for carbonation is MB8 and ME6 polymer-modified mortar.

In order to investigate the change of physicochemical properties of ginseng root starch during storage and heat treatment. the roots were stored for 15 days at 5℃, 15℃, 30℃ and 45℃, and heated for 15 hours at 60℃, 70℃, 80℃, 90℃, respectively. The starch content was decreased from about 40% to 23-26% and sucrose content was increased from 4% to 12-16% during storage for 15 days at 5-45℃. Maltose, which was not detected in fresh samples, was increased upto 8.5% during storage or heat treatment. Granular size of the starch was decreased and some of the granules were broken during storage. Amylose content in the starch was decreased from 33% to 20%, and blue value and alkali number of the starch were increased slightly, and solubility and swelling power of the starch were decreased during storage. The higher storage temperature and the longer storage time, the starch was more susceptible to gelatinize, and the viscosity of the starch was lowered with the susceptibility of gelatinization. The susceptibility of degradation of the starch by the amylase was increased and amylolytic activities in ginseng root were, also, increased during storage.

This study was performed to investigate: The ecological difference of two ecotypes "Seushan (northern) and "Cheju(southern)" The effect of temperature (low. high. alternative) and long day treatments on the growth and bulb formation in two ecotypes Translocation of growth regulators and contents of total sugars in garlic plants Identification of isozyme existing in garlic plants by the electrophoretic method. The results are summarized as follows: 1. The experiment of temperature and long day treatments. Sprouting and early growth of the southern type were accelerated by low iemperature treatment but those of long day treatment were not affected. In plant height and leaf sheath length. the southern type was increased more than the northern type until March 20 and the plants that were treated with low temperature were increased considerably as compared with the control There was no difference in the total leaf numbers between two ecotypes but low temperature treatment romoted those as compared to the control. 2. Ecological experiment of two regions The plant height of the southern type was accelerated until March 25 i n Cheju and March 10 in Suweon. but the plant height of the northern type was promoted after April 20. The growth of leaf length and leaf sheath lentth showed no dlfference durting winter. but after March 10 the southern type was increased in Suweon and Cheju. there was no difference in clove number and bulb weight within the regions and seeding time. but those of the southern type were increased as compared with the northern type 3 Analysis of sugar Low temperature treatment tended to increase concetrations of sugar as compard with control and the difference between cultivats was clear Friictosan was increased as the plants grew. especially at the later period of the whole growth with ever): treatment 4 Bioassay at growth regulators Af Rf 0.5-0.6 and Rf 0.4-0.5 Glbgberellin-like substances were detected from the leaf and leaf sheath of northern type and inhibitors were detected at Rf 0.7-0.9 While 5. The change of Isozyme patterns It was noted that the isozyme patterns were similar between two ecotypes in peroxidase. There was no difference at the bands which means acid phosphatase in two types. There were three or four bands which showed Malate dehydrogenase. but also showed the similar tendency according to the cultivars and every parts.

The purpose of this was to evaluate the ferrule effect of endodontically treated permolars as affected by various amounts of tooth structure. Forty recently extracted, intact premolars were used. The teeth were divided into four groups of ten each. In Group I, the coronal portions of the teeth were removed at the cemento-enamel junction. In Group Ⅱ, the coronal portions of the teeth were removed to 1mm above the cemento-enamel junction. In Group Ⅲ, the coronal portions of the teeth were removed to 2mm above the cemento-enamel junction. In Group Ⅳ, the coronal portions of the teeth were removed to 3mm above the cemento-enamel junction. Every tooth was endodontically treated and a prefabricated paralleled Para-post was inserted in each canal and a composite resin core was built to 7mm above the cemento-enamel Junction. Thereafter, a complete cast crown was made from nickel-chrome alloy and cemented with zinc phophate cement to each tooth. The failure loads of the specimens were measured by an Instron Universal testing machine. The mean values of failure loads for the four groups were statistically compared by studen't t-test. The results were as follows: 1. There was a statistically significant difference between the failure loads of Group I (removed at the cemento-enamel junction) and the others(p<0.05). 2. The mean values of the failure loads of the Group Ⅱ (removed to 1mm above the cementoenamel junction), Group Ⅲ (removed to 2mm above the cemento-enamel junction) and Group Ⅳ(removed to 3㎜ above the cemento-enamel junction) exhibited values the same order as Group Ⅳ (removed to 3mm above the cemento-enamel junction), Group Ⅱ (removed to 1mm above the cemento-enamel junction), Group Ⅲ (removed to 2mm above the cemento-enamel junction) but there was no statistically significant difference among them(p>0.05).

연구배경: 제대혈은 골수에 비해 많은 장점을 가지고 있음에도, 이식 후 성적에 있어 총세포수에 의해 좌우되며, 한 개의 태반으로부터 얻을 수 있는 총세포수의 한계가 있어 주로 소아에 국한되고 있다. 따라서 제대혈 응용의 확대를 위해 생착량을 늘이기 위한 방법으로 다중공여자에 의한 제대혈 혼합이식을 늘일 수 있는지 연구하기 위하여, 본 연구에서는 주조직적합성 형별로 조합된 제대혈을 NOD/ SCID 생쥐에 이식하는 방법으로, 혼합생착의 가능성을 연구하였다. 방법: 조합된 2개 공여자로부터 얻어진 제대혈들을 단일이식 및 혼합이식하여, 혼합이식된 숙주에 생착된 세포를 PCR-SSOP 방법을 사용하여 공여자 별로 추적하였다. 또한 각 공여자세포의 상대적 생착비율을 대조군인 단일제대혈 이식에서 얻어진 생착량과 비교하는 정량적 비교도 함께 하였다. 결과: 총단핵구를 혼합이식한 실험군에서는 주조직적합성의 일치도에 관계없이 한쪽공여자의 세포가 다른쪽에 비해 우세한 편향생착을 보였다. 그러나 임파구를 비롯한 Lineage 양성세포를 제거한 실험군에서는 주조직적합성의 불일치에도 불구하고 뚜렸한 생착의 공존이 관찰되었다. 결론: 본 연구는 제대혈의 생착량을 증가를 목적으로 총단핵구를 혼합이식할 경우 한쪽공여자의 세포에 의해 편중되며, 이것을 이식 후 생착과정에서의 두 종류의 세포의 경쟁에 의해 초래된다는 것을 보이고 있다. 또한 이러한 경쟁은 제대혈에 포함되어 있던 임파구들에 의한 것이며, 생착공존을 위하여는 공여자간 주조직적합성의 일치도 보다, 임파구의 제거가 더 중요하다는 것을 보여주고 있다. Background: Although umbilical cord blood (UCB) has been an attractive alternatives for bone marrow cells, application is limited to pediatric case due to limitation in total number of nucleated cells, that is a single most important factor for outcomes of UCB transplantation. Therefore, increasing overall engraftment by mixed transplantation of UCB derived from multiple donor should comprise one strategy to circumvent the posed limitation of UCB transplantation. In order to investigate the feasibility of establishing co-engraftment by multi-donor UCB cells, we carried out a xenotransaplantation study using NOD/SCID mice for systemic analysis of results on the input-based control of single unit transplantation. Methods: UCB units with various extent of HLA-matchings were co-transplanted into NOD/SCID mice along with single unit transplantation control. The relative contributions of engraftment by cells from each donor-derived were analyzed by HLA polymorphism using PCR-SSOP. Results: In all HLA-based mixed transplantation of total nucleated UCB cells, engraftment of one donor predominated over the other despite that equivalent amount of engraftments were achieved by single donor transplantation. When lineage depleted UCB units were co-transplanted, significant degree of co-engraftments were observed regardless of HLA disparity. Conclusion: Our result show that one donor cells dominate over the other in mixed UCB transplantation and that it is due to competition between donor cells during post-transplantation process. Our results suggest that immune cells contained in UCB unit mediate such competitioin and that 6 locus HLA matching would not be sufficient to prevent the competition.

This experiment was carried out to investigate the effects of overhead irrigation of Ethrel on after-ripening of kiwi fruit, and to improve marketability and decrease operating cost as to ripen kiwi fruit at the stage of consumption. In 1994, the eight-year-old Hayward which were planted in farm field at Haenam Okchen were treated with 100ppm, 150ppm and 200ppm overhead irrigation of ethephon on September 25, September 30 and October 5 respectively. In 1995, the nine-year-old Hayward which were planted in windbreak net house at Moonlae Haenam were treated with 40, 70 and 100ppm overhead irrigation of Ethephon on October 5, October 10 and October 15 respectively. As the result of at 10 and 20 days after treatment, in 1994, the firmness was much low as to show 0.8 to 0.95kg at 10 days after treatment, 0.2 to 0.33kg at 20 days after treatment. And sduble solid content was 10.6 to 11.7˚ Bx and abscission rate was 10.3 to 35.9%. Therefore, the marketability were tended to be showed low. In 1995, as that firmness was 3.2 to 3.7kg, last soluble solid content after harvesting was 13.8 to 14.0˚ Bx and abscission rate was 0%, there was no problems in marketability and marketing. Therefore, this results were demonstrated that the treatment after October 10 in 70 to 100ppm ethephon can be improved marketability and marketing of kiwifruit.
