The X-linked adrenoleukodystrophy (X-ALD) is a peroxisomal disease by defects of ABCD1 gene on chromosome Xq28 leading to accumulation of saturated very long chain fatty acids (VLCFA), progressive demyelination and adrenal insufficiency. A 4-year-old boy was visited hospital with the chief compliant of hyperpigmentation beginning at 2-years old. Serum adrenocorticotropic hormone (ACTH) and cortisol concentration were compatible with adrenal insufficiency. The elevated plasmatic concentration of VLCFA and genotype analysis with sequencing of ABCD1 gene established the diagnosis of X-ALD. Brain MRI showed no abnormal high signal intensity on the white matter. Steroid replacement was started with good response. He initiated Lorenzo's oil with restriction of VLCFA by reducing the intake of fatty foods. The author highlight the importance of suspecting of X-ALD in the etiology of primary adrenal insufficiency as the first sign of the disease.

In this study we reviewed how acid rain as the global environmental problems was dealt with geography textbooks from Korea and England. The results are as follows. First, unlike geography textbooks from England, the concept and criteria of acid rain are not explained exactly in Korea geography textbooks. Second, whereas the cause of acid rain was explained with natural and artificial factors in geography textbooks from England, in Korea the artificial factors only were explained. But if the artificial factors only will be introduced to students, they may misunderstand about the acid rain. Third, the results and policies of acid rain were provided in geography textbooks from Korea and England. But whereas they were deal with separately in Korea, in textbooks from England they were provided with their patterns and concrete cases. So it is necessary to provide the exact concept, results and processes of the global environmental problems structurally in geography textbooks. And it is necessary to provide the results and their policies of the global environmental problems with concrete cases for students' understanding and sympathy about them. If the concepts and causes of global environmental problems are not understood previously, it is possible to stimulate only the moral and ethical aspects too much when the results and policies of them is introduced in geography textbooks.

The purpose of this study is to examine the publication, composition, method of composition, and acceptance patterns of JujaDaejeon anthologies edited by Joseon scholars in the Joseon dynasty. When a large amount of JujaDaejeon was published in the 16^th century, anthologies of JujajaDaejeon was compiled, published and learned as a way to understand it. A total of 13 kinds of JujajaDaejeon anthologies were published, including six kinds in the early Joseon period and seven kinds in the late Joseon period. And the composition of main anthologies showed a trend that was supplemented by Jeong Gyeong-se's Jumunjakhae from Lee Hwang's Jujaseojeolyo, and aggregated into Song Si-yeol's Jeoljaktongpyeon(boyu). JujaDaejeon consists of total 3,645 works except for poems. Among them, 1,734 works were selected by 13 anthologies. The theme of a work with a high cumulative number of selections is the virtue and attitude of the king, policy proposals, the appointment of talent, the duty of subjects, criteria for evaluating historical figures, opposition to harmony with Jin and territorial restoration, and academic discussions. This study is expected to be meaningful in the field of the research on the acceptance of the foreign books and acceptance of the Zhu Xi's works in the Joseon dynasty.

The tribe Neillieae, a small group of about 18 species in the Rosaceae, comprises three taxonomically difficult genera, Neillia, Physocarpus, and Stephanandra. The tribe, characterized by lobed leaves with persistent or deciduous stipules and ovoid, shiny seeds with copious endosperm, is strongly supported as a monophyletic group by a variety of lines of molecular evidence. Due to the high amount of morphological variation across the three genera and the species in tribe Neillieae, conflicting classification schemes and numerous species have been proposed over the past three centuries. However, no comprehensive systematic study of the group, including all species across their geographic ranges, has ever been undertaken. As part of a taxonomic revision of tribe Neillieae, a revision of Physocarpus based on the morphological examination of herbarium specimens, including types, and field observation is presented. Artificial keys, comprehensive nomenclatural treatments, descriptions, distribution maps, and lists of specimens examined are provided. Six species in Physocarpus are recognized. A lectotype is here designated for the following species: Opulaster pubescens, Opulaster ramaleyi, Spiraea opulifolia var. parvifolia, Spiraea opulifolia var. tomentella, Physocarpus michiganensis, and Physocarpus missouriensis.

The purpose of this study was to analyze the research ethics elementary and secondary gifted students enrolled in science-gifted education center of university and to get the implications of research ethics education. 180 elementary and secondary gifted students and 180 general students were participated. The results obtained from this study were as follows: First, the item, such as 'The researchers must have self-esteem and responsibility in their study', both the gifted students and the general students showed the highest perception. On the contrary, the item 'I think that it is right to exclude the person who didn't participate in research' both the gifted students and the general students showed the lowest perception. And gifted students' perception on research ethics was higher than the general students' on the whole. There was a statistically significant difference between two groups(p<.05). Second, the scientifically gifted students' research ethics in 'basic attitude of the researchers' was significantly higher than mathematically gifted students' and IT gifted students' (p<.05). Third, there was a statistically significant difference between the elementary gifted students and secondary gifted students in 'ethics of thought and expression' (p<.05). Fourth, experience in research ethics education and the number of research experience was significantly effect on perception of research ethics. There was a statistically significant interaction effect between gifted students and general students in 'science, technology, biomedical research ethics' items(p<.05).

In the process of site selection for a radioactive waste disposal, site characterization must be carried out to obtain input parameters to assess the safety and feasibility of deep geological repository. In this paper, methodologies of site characterization for radioactive waste disposal in Korea were suggested based on foreign cases of site characterization. The IAEA recommends that site characterization for radioactive waste disposal should be performed through stepwise processes, in which the site characterization period is divided into preliminary and detailed stages, in sequence. This methodology was followed by several foreign countries for their geological disposal programs. General properties related to geological environments were obtained at the preliminary site characterization stage; more detailed site characteristics were investigated during the detailed site characterization stage. The results of investigation of geology, hydro-geology, geochemistry, rock mechanics, solute transport and thermal properties at a site have to be combined and constructed in the form of a site descriptive model. Based on this site descriptive model, the site characteristics can be evaluated to assess suitability of site for radioactive waste disposal. According to foreign site characterization cases, 7 or 8 years are expected to be needed for site characterization; however, the time required may increase if the no proper national strategy is provided.

Chlorinated ethylenes such as perchloroethylene (PCE) and trichloroethylene (TCE) are widely used as industrial solvents and degreasing agents. Because of improper handling, these highly toxic chlorinated ethylenes have been often detected from contaminated soils and groundwater. Biological PCE dechlorination activities were tested in bacterial cultures inoculated with 10 different environmental samples from sediments, sludges, soils, and groundwater. Of these, the sediment using culture (SE 2) was selected and used for establishing an efficient PCE dechlorinating enrichment culture since it showed the highest activity of dechlorination. The cathode chamber of bioelectrochemical system (BES) was inoculated with the enrichment culture and the system with a cathode polarized at -500 mV (Vs Ag/AgCl) was operated under fed-batch mode. PCE was dechlorinated to ethylene via TCE, cis-dichloroethylene, and vinyl chloride. Microbial community analysis with polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) showed that the microbial community in the enrichment culture was significantly changed during the bio-electrochemical PCE dechlorination in the BES. The communities of suspended-growth bacteria and attached-growth bacteria on the cathode surface are also quite different from each other, indicating that there were some differences in their mechanisms receiving electrons from electrode for PCE dechlorination. Further detailed research to investigate electron transfer mechanism would make the bioelctrochemical dechlorination technique greatly useful for bioremediation of soil and groundwater contaminated with chlorinated ethylenes.

It is very difficult to forecast accurately a damage from the natural disaster which occurs frequently due to the climate change. When the significant weather event is forecast, it will be able to minimize a damage with the suitable prevention action. But 2000's our country meterological disaster damage is a several trillion won. Therefore, this paper analyzes Korea Meterological Administration, Japan Meterological Agency, television and newspaper have reported, information substance, transmission system, an ex post facto valuation about typhoon Nabi between september $5{\sim}7$ in 2005 and heavy rainfall in 1998 at Japan. Through the investigation, we want to present basic data order to rises the application effect of disaster prevention meterological information. We think KMA must present many information report to promote a people's understanding about the meterological information and the serious disaster situation. Also the disaster damage estimation model development is necessary, which forecasts the accurate damage scale due to the weather event, such as typhoon, heavy rainfall, strong wind. And also we think the KMA, National Emergency Management Agency, related agency, television and newspaper must positive reports the contents which is suitable to disaster response phases and an ex post facto examination. Then it grasps the problem of disaster prevention meterological information and must improve effectively.
