By gelation with sodium silicate and phosphorous oxide in binary system, we investigated the possibility to fix the volatile alkali metal chlorides in a highly stable matrix at high temperature if the product gel is further solidified to form glass or ceramic waste form. The binary system with different metal chloride(MCl) loadings underwent gelation reaction at 70℃ for 1 day and dried at 110℃ for 1 day. XRD analysis showed that all the dried gel contained NaCl and some unknown crystalline phase. From the experimental results, the reaction mechanism can be proposed as follows. Also, the possibility of Cs vaporization could be lowered by the application of the new gel-route stabilization/solidification to treat waste salt. (G,Na)+MCl→(G,M)+NaCl, (G.H)+MCI→(G,M)+HCl.

Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

The primary culture of human nasal epithelial cell monolayer was performed on a Transwell. The effect of various factors on the tight junction formation was observed in order to develop an in vitro experimental system for nasal transport studies. Human nasal epithelial cells, collected from human normal inferior turbinates, were plated onto diverse inserts. After 4 days, media of the apical surface was removed for air-liquid interface (ALI) culture. Morphological characteristics was observed by transmission electron microscopy (TEM). A polyester membrane of 0.4 μm pore size was determined as the most effective insert based on the change in the transepithelial electric resistance (TEER) value as well as the ^14C-mannitol transport study. The ALI method was effective in developing the tight junction as observed in the further increase in the TEER value and reduction in the permeability coefficient (P_app) of ^14C-mannitol transport. Results of the transport study of a model drug, budesonide, showed that the primary culture system developed in this study could be further developed and applied for in vitro nasal transport studies.

This study represents the present situation and the future prospect of waste management, the regulations for environmental protection, and the criteria and procedure for selecting the waste landfill sites using GIS. The criteria for selecting the waste landfill sites composes of 8 items ; topography, hydrology, geology, ecology, location, landuse, society, and others. In order to secure the accuracy and objectivity for selection of suitable waste landfill sites, individual weights of 8 items were introduced using the concept of fuzzy set. Also, unacceptable conditions were described for deciding which sites should not be selected because of environmental concerns. As showed in the result obtained by the case study in Chinju, GIS technology was demonstrated as a useful tool for the management and analysis of environmental data in the suitability analysis for the waste landfill sites.

敎科書制度에 대한 憲法裁判所와 法院의 判例分析 : 敎科書制度의 발전을 위한 示唆點과 批判

Despite the apparent pro status quo arguments presented in the decisions of Korean judicial courts and the Korean Constitutional Court, their reasoning reveals different aspects of their real opinions. Even though the prevailing opinions of the courts confirm the legality of current regulatory system, I believe, most judges of the courts hoped to reform the current textbook regulations. I have found a number of useful reformative arguments from the reasoning of their decisions. From these arguments, I probed the possible reformative model of the textbook regulation system. First, the textbook adoption system must be regulated not by a Presidential decree but by a Statute enacted by the National Congress. Second, the National publication system of school textbooks must be abolished. Third, participatory rights of the parents should be enhanced, so much so that they can take part in selecting the textbooks. Fourth, procedural regulations should be introduced to the current textbook adoption process to restrict the discretionary power of the Textbook Adoption Committee and the other relevant administrative agencies. Fifth, In order to facilitate the judicial review for cultural diversity, the statutory clauses that provide guarantee against political and philosophical monopoly of the prevailing group should be created by National Congress.

More lawyers than ever in the Republic of Korea have a growing interest in Alternative Dispute Resolution (ADR). Even in the area of administrative law, lawyers are asking for more efficient alternative methods of dispute resolution. Despite the interest being generated in the Korean legal community by ADR the Korean ADR movement in the sphere of administrative law has net yet been adequately activated. In my opinion, some prerequisites must be met to energize this movement. At first, more sophisticated methods of ADR that are particularly suitable to Korean legal culture should be created. Moreover, ADR proponents have to cope with the theoretical difficulties involved in introducing ADR into administrative law, because it is not traditionally allowed in Korean legal theory to settle an administrative law dispute through negotiation. In addition, legislative reform of ADR is essential in the attempt to improve the above-mentioned problems. Under these circumstances, this article examines 1) the cultural and political background of ADR in Korean administrative law; 2) how the current ADR system of Korea is developing in the public law area; 3) whether the vexing theoretical question surrounding negotiation in Korean administrative law will be cleared up. This article aims to answer these questions in order to offer clear solutions that will help create a more effective ADR system in Korean administrative law. In other words, this article attempts to overview the current ADR system of the Republic of Korea, and to show how this system can be reshaped in a new direction. In the process of analyzing and evaluating the Korean ADR system and its legal theories in this article, information from the American ADR system and perspectives from American theories about ADR in administrative law are widely referred to.
