This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

The solid solutions of the ?? systems with χ=1.00, 0.75 and 0.50 are prepared from stoichiometric mixtures of carbonate (SrCO₃), nitrate (Fe (NO₃)₃·9H₂O) and oxide (La₂O₃) by heating at 1300℃ for three days. Crystallographic structures of the solutions are all simple cubic systems and the lattice parameters of the cubic unit cells are enlarged with the introduction of lantanium according to their X-ray diffraction analysis. The mixed valence state of two kinds of Fe ion in the ferrite systems is analyzed by the Mohr salt titration method. It is possible to produce the nonstoichiometric compounds such as ?? by the appropriate heating treatment of the solutions under atmospheric air or oxygen pressure for a long time. The crystallographic structure and the nonstoichiometric compositions of the ?? systems are discussed with relation to their physical properties.

A Mechanical valve is one of the most widely used implantable artificial organs and its reliability is so important that is failure means the death of the patient. Thrombosis si the most common cause of mechanical valve failure, therefore, early noninvasive detection of mechanical valve thrombosis is essential. The objective of this research was to detect thrombosis formation by using spectiral analysis an a neural network. Using a microphone and an amplifier, we measured the soud form a mechanial valve which was attached to a pneumatic ventricular assist device. The should was sampled by an A/D converter(DaqBook 100), and the periodogram was the amin algorithm for obtaining the spectrum. We made the thrombosis models by uisng pellethance and silicon on thte valvular disk around the sewing ring and and on fibrous tissue growth across the orifice of the valve. The performance of the measurement system was tested by sung 1-㎾ sinusoidal wave. The measurement system properly detected 1-㎑ spectrum, as expected. The spectra of a nomal valve and 5 kinds of thrombotic valves were obtained, and primary and secondary peaks appeared in each spectral waveform. We found tat the secondary peak changed according to the thrombosis model. Thus, to distinguish the secondary peak of normal valve and form that of thrombotic valve quantatively, we employed a 3-layers, and 1 output. This trained neural network could distinguish betwen a normal and a thrombotic valve with more than 90% probability. In conclusion, noninvasive monitoring of an implanted mechanical valve is possible by analyzing the acoustical spectrum through the use a neural network algorithm. This method will be applied to the performance evaluation of other implantalbe artificial organs.

During the 36-year-long Japanese rule of Korea, many reformations have been made in physical Education politics, economy, culture and other social realms. But these reforms have only served the imperalist Japan's interests, resulting in misleading Korea modernization and sacrificing the Korean people's identity. In this respect, the recent boom of research on modern Korean history is rather forcused on re-orienting the distorted historical viewpoints and re-establishing on people's subjectivity. Unlike other scientific areas, however, the research of modern Korean history of physical education is troubled a lot with as well as insufficient concrete data and materials concerning that age. Therefore, this researcher intends to view social physical education in Korea during the severest Japanese military rule from 1910 to 1919 from the nationalistic viewpoint some major items deal with in this study are 1) The nationalistic character of Athletic meet 2) The nationalistic character of YMCA'S Activity of physical education 3) The nationalistic character of Athletics

This study was designed to examine the tissue levels of interleukin-1α(IL-1α), interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) in inflamed human dental pulps and periapical lesions, and to determine the relationship between each cytokine and pulpal and periapical pathosis. The pulps used in this experiment, were obtained in routine endodontic treatment and the periapical lesions in periapical surgery after clinical diagnoses were performed. These specimens were divided into four groups as normal pulp group(control group, n=9), acute pulpitis group(n=9), chronic pulpitis group(n=10) and periapical lesion group(n=18) and stored in liquid N_2. For extract preparation, tissues were finely minced with a scalpel, and the fragments were incubated in 0.5㎖ homogenizing buffer (0.1 mol/L potassium chloride, 0.02 mol/L TRIS; pH=7.6) for two hours and grinded with glass homogenizer. Debris was removed by centrifugation and supernatants were immediately tested with enzymelinked immunosorbent assay(ELISA, R&D Co., Minneapolis, USA). Following results were obtained ; 1. The concentrations of IL-1α in all experimental groups were significantly higher than in control group(p<0.05). And the concentrations of IL-1α in periapical lesion group were somewhat higher than in two pulpitis groups, but the differences among those groups were not stastically significant(p>0.05). 2. The concentrations of IL-1β in all experimental groups were significantly higher than in control group(p<0.05), and all the experimental groups expressed similar concentrations. 3. The concentrations of TNT-α in all experimental groups were higher than in control group but only the differences between chronic pulpitis group and control group were statistically significant(p<0.05). And the concentrations of TNT-α in acute and chronic pulpitis groups were higher than in periapical lesion group but only the differences between chronic pulpitis group and periapical lesion group were statistically significant(p<0.05). 4. There was significant correlation only between IL-1α and IL-1β in periapical lesion group(p<0.05).

Three kinds of toxic heavy metals, such as lead, copper, and cadmium, existing abundantly in contaminated soils were selected to investigate pH change, electroosmotic flow, and the removal rate in the application of electrokinetic process. In the change of pHs, they reached to about 12 and 2 at each cathodic and anodic region, respectively, and maintained for reaction being proceeded. Electroosmotic flow rates were not influenced by the kind of metal species but by electropotential gradient. On the soils contaminated by each metal, the removal rate of Cd was the fastest among three as in the order of Cd>Pb>Cu. While on the soils contaminated by mixed metal species, Cu was the fastest. Metal species transported by electrokinetic processes were distributed in between 0.9 and 1.0 of normalized region. In the case of soils contaminated by one kind of metal. the relative concentrations of Pb and Cd estimated in between normalized region 0.9 and 1.0 were 5.2 and 5.7, respectively.
