The noise in factory or constructing field is controled by the Ministry of Environment, But there in no regulation of administrative plan on combat plane's noise. For this reason, the citizens lived around airfield are suffered from noise harm. On the purpose of this study, we investigate actual conditions in airfield and draw up lay-out a scheme for preventing noise harm from airplane, which can conduce pleasant life that is assured by the constitutional law.

As a part of basic investigation and research the present condition and characteristics of livestock wastewater production in Sogwipo City is accessed. Based on the current data a trend of the livestock wastewater production for the furture is predicted. This is our purpose to facilitate this report as a basic guide-line for the furture livestock wastewater treatment. The result of this study are summarized as follows : 1. Breeding households of livestocks (swine. beef cattle, chicken) decrease every year, but the number of heads per household are increased each year. 2. BOD-loading per day of beef cattles wastewaters investigated 59.2kg. and pollution loadings are suspected 38.3 BODkg/day at 2001 year. 3. The quanity of swine wastewaters were counted 12.4ℓ/head·day, BOD-loadings were reached 45.6kg and suspected same values at 2001 year

A 15-year-old patient, who had been diagnosed and treated as Burkitt cell type acute lymphoblastic leukemia (ALLL3) already, visited our department. He complained of gingival enlargement and loosening teeth 1 month ago. The clinical examination revealed anterior open bite, gingival enlargement, and nontender swelling particularly in molar regions of both jaws. Deep periodontal pockets and severe mobility was shown on most of the teeth. The panoramic radiographs showed severe bone destruction and extrusion of the molars. The contrast enhanced CT showed multiple enhanced mass and bone marrow obliteration in both jaws. Chemotherapy was done and the swelling was subsided at 1 month later. In conclusion, radiologic findings of leukemia with soft tissue mass, known as chloroma or granulocytic sarcoma, mimic those of lymphoma, so blood test may be needed for the final diagnosis.

The purpose of this research is to obtain the characteristics of strain and stress in the vacuum pressure vessel. The vacuum pressure vessel is used to many of industrial devices and cooling tower system. The vessel is under the vacuum pressure in this research, and we analyzed the stress on the vessel surface. As the experimental set up, we introduced the Static Strain Measurement(UCAM 70A, Kyowa) system. The environmental condition of vessel is reserved under vacuum pressure 50mmHg, and the vacuum pressure was made by a ejector pump system.

ation of biomedical applications.Semiconductor quantum dots have been demonstrated as excellent uorescent probes. However, they suer from the intrinsic limi-tations of optical imaging systems such as low penetration depth and large background uorescence. Magnetic nanocrystals are nowemerging in biomedical applications with new possibilities. We have demonstrated the production of high quality water-soluble ironoxide (WSIO) nanocrystals by thermal decomposition method.stability to withstand harsh biological conditions, Conjugation of biologically functional molecules to nanocrystals produce nanohybridsthat have multi-functionality such as detection, diagnosis, and therapeutics. However, further development of in vivo imaging applica-tions of these molecules has been very limited with very few successful in vivo demonstrations. In addition to therapeutic antibody, theability to incorporate genes or drugs into detectable site-targeted nanosystems may represent a whole new paradigm in therapeutics.for development and nanocrystals will bring improvement in bio-medical sciences.

Objective Electroconvulsive seizure (ECS) is a potent treatment modality for various neuropsychiatric diseases, including Parkinson disease (PD). Recent animal studies showed that repeated ECS activates autophagy signaling, the impairment of which is known to be involved in PD. However, the effectiveness of ECS on PD and its therapeutic mechanisms have not yet been investigated in detail. Methods Systemic injection of a neurotoxin 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP), which destroys dopaminergic neurons in the substantia nigra compacta (SNc), in mice was utilized to induce an animal model of PD. Mice were treated with ECS 3 times per week for 2 weeks. Behavioral changes were measured with a rotarod test. Molecular changes related to autophagy signaling in midbrain including SNc, striatum, and prefrontal cortex were analyzed with immunohistochemistry and immunoblot analyses. Results Repeated ECS treatments normalized the motor deficits and the loss of dopamiergic neurons in SNc of the MPTP PD mouse model. In the mouse model, LC3-II, an autophagy marker, was increased in midbrain while decreased in prefrontal cortex, both of which were reversed by repeated ECS treatments. In the prefrontal cortex, ECS-induced LC3-II increase was accompanied with AMP-activated protein kinase (AMPK)-Unc-51-like kinase 1-Beclin1 pathway activation and inhibition of mamalian target of rapamycin signaling which promotes autophagy initiation. Conclusion The findings revealed the therapeutic effects of repeated ECS treatments on PD, which could be attributed to the neuroprotective effect of ECS mediated by AMPK-autophagy signaling.

전남동부연안권 및 섬진강유역권의 생태환경을 중심으로, 2차년도 동안 섬진강 본류와 지류가 관류하는 10개 시군을 대상으로 지질관광(Geotourism)의 가능성을 고찰하였다. 1차년도(2008년 7월 ~ 2009년 6월)에는 고흥, 순천, 구례, 여수 등 총 5개 지역에 걸쳐 현장조사를 실시하였고, 2차년도(2009년 7월 ~ 2010년 6월)에는 남원, 곡성, 광양, 하동, 남해에 이르기까지 12개월에 걸쳐 조사 하였다. 조사가 미진한 지역에 대해서는 2개월 동안 보완조사를 실시하였다. 그리고 해남 등 4개 공룡화석지도 지오사이트 가능성을 추가하였다. 지질관광이 이루어지기 위해서는 전남동부연안권 및 섬진강유역권에 대한 풍부한 지질학적 자료와 타 지역과의 연계성, 그리고 타 분야와의 연계성 등 많은 자료와 연구가 뒷받침 되어야 한다. 이러한 조사 결과를 토대로, 각각의 지오사이트의 지질유산 및 문화재를 선정하여 지질관광으로의 가능성을 고찰해보고, 역사문화지도와의 연계성을 확보하여 관광객이하 전 국민들이 보다 쉽고 편리하게 지질관광을 이용할 수 있도록 조성할 것이다. Validities of Geotourism to ten cities and counties which main and branched streams of Seomjin River run were considered for the ecosystematic scope to the areas around eastern Jeonnam coast and the river during twelve months. In first year, field surveys for 5 areas of Goheung, Suncheon, Gurye and Yeosu were carried out, and, next year, the surveys for another 5 areas of Namweon, Gokseong, Gwangyang, Hadong and Namhae were performed. And, 4 dinosaur fossil sites including Haenam area were considered in the the aspect of Geotourism. For areas necessary to added surveys, two month surveys were carried out. For appropriate Geotourism, it should be prepared a lot of data and studies including the geology of above areas and interrelationships to other areas. From above results, It should organizes that most people, easily, come into close and use those geological and cultural sites as useful Geosites, on the basis of the consideration on Geotourism and interrelationship with historical and cultural map.
