Purpose : On outpatient facilities, our sedation protocol focuses on the intermittent bolus injections of midazolam intravenously, according to patient's and operator's needs during the dental treatment. This multicenter retrospective study was aimed to prove the efficiency and safety of our sedation protocol. Patients and Methods : In three centers using the same outpatient sedation protocol for dental treatment (Division of Oral and Maxillofacial Surgery/Department of Dentistry in Hanyang University Medical Center, S-plant Dental Hospital. and Grand Oral and Maxillofacial Surgery), total 937 patients had various dental treatments under intravenous conscious sedations with independent patient monitoring from March 2006 to March 2009. By reviewing charts, we analyzed the results of sedation and dental treatment, retrospectively. Results : Our sedation protocol had no severe postoperative complications requiring admission. while showing good compatibility with almost all dental treatments, with acceptable satisfaction of both patients and operators. Conclusion : We assure that our sedation protocol can be used efficiently and safely on routine outpatient basis. We also hope that this study will provide the concrete concepts to common dental practitioners, who desire to perform sedation for dental treatment.

The purpose of this study was to examine the relationship between bone density and dietary intake for college women in their twenties. This study was performed on 160 female college students residing in Gangwon-do. It was conducted using ultrasound measurement of calcaneus bone density, anthropometric checkup and food-frequency questionnaires (FFQ) comprising 94 kinds of commonly consumed foods. Subjects were divided into two groups according to the T-score of bone density: a normal group (n = 113 persons, T-score ${\geq}1$) and a risk group (n = 47, T-score < 1.0). The average age of the subjects was 20.17 years and there was no significant difference between the two groups. Body weight and body fat percentage of the normal group were significantly higher than those of the risk group. The mean daily energy intake of the normal group was significantly higher than that of the risk group. Also, protein, fat, vitamin A, niacin, vitamin B6, folate, calcium, phosphorus, sodium, potassium, iron and zinc intake for the normal group were significantly higher than for the risk group. For the intake of the commonly consumed foods (or dishes) listed in FFQ, the mean daily intake amount of loaf bread, rice cake, potatoes, spicy beef soup, cucumber, seasoned spinach perilla leaves, crown daisy, stir-fried mushroom, sea mustard, beef rib, ham, chicken, mackerel, common squid, drink type curd yogurt, oriental melon and chocolate in the normal group was significantly higher than in the risk group. While, the mean daily intake of ramyun (instant noodle) and carbonated beverage by the normal group was significantly lower than that of the risk group. In conclusion, 20 something female college students showed a higher rate (26.9%) of the bone mineral density risk group (osteopenia or osteoporosis). For the risk group, the levels of nutrient and food intake were lower than in the normal group. Therefore, the bone density risk group needs to increase their nutrient intake and diet quality by increasing the intake of various foods. In addition, they should decrease the intake of foods, which are negative for skeletal health such as instant noodles and carbonated beverages.

During last five years several workshops and seminars among social work educators, in and out country, has taken place. In those gatherings there has been, criticism on American model on which curriculum of social work in Korea has mainly based, and many proposals which most developing countries should consider and adopt for developing their own curriculums. The proposals could be summarized as follows; 1. Specification of developmental functions of social work should be made so that the curriculum could involve. It also must come from own societal needs and own national development task. 2. Social work should participate and make contribution to plan and solve the main social problems in own countries. 3. Clarification of educational objective in undergraduate level should be made and one of them must be related to the first professional degree. 4. There should be the courses which provide the content of macro level participation. How much of the proposals are reflected in the current curriculum of Korea? What are the problems Korean social work education has been faced in connection with reflecting the proposals? What kinds of task we should or could perform in order to adopt the proposals? These are the questions which deserved to be studied. The followings are the answers to the questions; 1. The new courses such as social welfare policy and planning, Social Development, Population Dynamics and Family Planning, Social problems, Special Issues in Social Welfare, etc, are placed in the curriculum. 2. Though the new courses are added the courses of case work, group work, and community organization are strongly remained it means that integrative method is not quite adopted and that conflicts are taking place between new and old fashion. 3. Fieldwork placement policy has been changes from concurrent to block and from social work method oriented to social problem oriented. 4. There are lack of integration among the all courses, of consistency between pre and post courses and connection among the related courses. 5. Establishment of image of social worker with B, A. degree should be urgently taken place. It can't be done by social work field alone but by cooperation with all the forces related to the social work practice. 6. B. A. graduate should have a common base of knowledge and competence. It could be come from the clear and specified objectives of undergraduate level education. And agreement among the member schools on the objectives can call on the fundamental similarities in each curriculums. Different programs from one school to another can be tolerated as long as there are fundamental similarities among the schools. Basic concepts and framework of social work should be kept clearly. It is a slow and long process to make social work recognized as a profession in the developing countries. Korea can't be and exception. Failure of having social work be indegenous can't be the reason to refuse an change the basic concepts of social work. One of he most important task which social work education in Korea must achieve in the near future is to establish the minimum requirement courses in the curriculum. Social work field, on the other hand, must find the positions for the social works in the various settings and institute. Clear role and image of social worker can be obtained by doing that.

Background: Melanoma antigen genes (MAGE) are expressed in many human malignant cells and are silent in normal tissues other than in testis and in placenta. But MAGE expression in benign lung diseases, such as pulmonary tuberculosis or cases with severe inflammation, needs further evaluation to overcome false-positive findings. We evaluated detection rates of the melanoma antigen genes (MAGE) RT-nested PCR in bronchoscopic washing samples from patients with benign lung disease, as well as in patients with malignancies. Methods: Bronchial washing fluid from 122 patients was used for cytological examination and MAGE gene detection using RT-nested-PCR of common A1-6 mRNA. We compared the results from the RT-nested PCR and the pathologic or bacteriologic diagnosis. We also analyzed the expression rate and false positive rate of MAGE gene. Results: Among 122 subjects, lung cancer was diagnosed in 23 patients and benign lung disease was diagnosed in 99 patients. In patients with lung cancer, the positive rate of MAGE expression was 47.8% (11/23) and in benign lung disease group, the expression rate was 14.1% (14/99). Among benign lung disease group, the expression rate of MAGE gene (25.0%) in patients with pulmonary tuberculosis (11/44) was especially high. Conclusion: MAGE A1-6 RT-nested PCR of bronchial washing fluid can be used as a complementary method in lung cancer, but that test results in a high false positive rate in tuberculosis patients.

Purpose: The purpose of this study was to investigate on primary bone tumors of fibula. Materials and Methods: Patients who received operative treatment from January 1993 to December 2005 for primary bone tumors of fibula were analyzed for clinical outcomes. Results: There were 17 patients(10 males, 7 females) who were diagnosed for primary bone tumors of fibula. Osteochondroma was the most common diagnosis and others were osteosarcoma, fibrous dysplasia. The malignant bone tumors were 10.5% of all fibula tumors. There were 12 cases on proximal, 4 cases on mid shaft, and 1 cases on distal part of fibula. At the final follow up, 14 patients reported patient satisfaction of either excellent or good. Conclusion: Bone tumor of fibula doesn't need reconstruction after the resection unless it invades tibia or its site distal, which enables easy surgical resection. However, generally it is rare and accompany with vague symptoms, so careful approach to diagnosis is necessary because late diagnosis can mean the needs for amputation.

The purpose of this study is to analyze the major issues discussed among Parties and provide a framework for predicting the agreements on those issues, prior to the final negotiation on a new legally-binding agreement on climate change adaptation in the United Nations Framework Convention on Climate Change (UNFCCC). The analyses of documents, adaptation actions, and work of the Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP) under the UNFCCC informed that the adaptation issue has primarily been focused on the support of developed country Parties for the adaptation of developing country Parties following the principle of the Convention, Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC). Three-year work of the ADP acknowledged the major issues on adaptation in the new climate agreement, which would be categorized as long-term and global aspects, commitments/contributions/actions, monitoring and evaluation, institutional arrangements, and loss and damage. A final agreement on each issue could be predicted by setting a zone of possible agreement in-between the two extremes of developing and developed country Parties and considering three major elements affecting the Parties' positions, national priority, adaptation action, and social expectation, which are proposed in this study. The three major elements should be considered in a balanced manner by Parties to draw a durable agreement that will enhance global adaptation actions from a long-term perspective. That is, the agreement needs to reflect adaptation actions occurring outside the Convention as well as social expectations for adaptation. It is expected that the new agreement on climate change adaptation, from a long-term and global perspective, would be an opportunity to reduce vulnerability and build resilience to climate change by incorporating global expectations.

Interlibrary loan has been a very common library service in the developed countries but it is yet to be actualized formerly in Korea. As Korea is moving toward an information society where all the individual user's request in the library should be met, we need to understand, in detail, the theory and practice of interlibrary loan service. As various information technology has been applied to the libraries, the libraries became the open system. Thus, the libraries become more cooperative, form networks, and make interlibrary loan service available. This study is based on the following three hypothesis formulated from the systems theory. 1. If libraries cooperate each other and form some kind of networks by mail, computers or telecommunications, they become the open system. 2. If a library develops as the open system, interlibrary loan becomes available in the library. 3. If the interlibrary loan system works, the role of the librarians will be changed. The research was carried out by analyzing the various studies about interlibrary loan service and by examining the interlibrary loan systerns presently working in the U.S.. The conclusions are reached deductively from the data. Some of the terminology used are defined as follows: System: a network of interrelated procedures that are joined together to perform an activity or to accomplish a specific objective. It is, in effect, all the ingredient which make up the whole. Cooperation: Working together to benefit participant libraries. Network: a much more structured type of cooperation in which definite regions or areas are connected by electronic or other means to promote interlibrary loaning of materials, in-service traing & other sharing of resources. Interlibrary loan: the lending of books between libraries. The model of cooperation or networks was used to be (1) a star type, (2) a hieranchical type, (3) a distributed type or (4) the combination of aforementioned three. However, the development of the telecommunications and computers enables all kinds of libraires cooperate together. Interlibrary loan service starts with the needs of user's information. The information have to be logically accessed through bibliographies, computers, electronic mails and satellite communications. And the logical access requires the information technology and the libraries become cooperative. The physical access to the information follows next but only traditional method of mail and some commercial service are currently available for this purpose. Therefore, researches are needed to develop this physical access. If the libraries form networks, the microaspect of library changes accordingly as the macroaspect changes. If the libraries . cooperate to become one large world library, the librarians plan, organize, control library operations and report the results. And the librarians work inside and outside of the library to cooperate with other libraries. Only the cooperation of the libraries will enhance interlibrary loan and the Korean librarians have to be prepared to accept the new role of librarianship for the interlibrary loan service.

The interest of people is rising on water leisure and the population of water sports is increasing with expanded nationwide roads and 5-day work system for income elevation. However, there are many discussions about the way to prevent the accident related to water leisure activities. Water Leisure Safety Regulation was enacted in 1999 as a part of the way and revised in 2005. Therefore it needs to grasp the present state of water leisure activities and analyze the actual condition of consciousness. For the analysis. the question survey was conducted on water leisurers in the focus with regulation of the revised so that the degree of relevance and correlation between mutual variables were analyzed by Frequency and Crosstabs. From this study we found that more than $60\%$ of water leisurers thought registration, safety instruction, insurance, and safety inspection necessary and there was a characteristic common inclination to all for necessity to impose legal controls on water leisure activities as the level of dissatisfaction for water leisure apparatus and cognition for necessity of insurance was high.

Diabetes mellitus, the most common metabolic disorder, is divided into two types: type 1 and type 2. The essential treatment of type 1 diabetes, caused by immune-mediated destruction of ${\beta}-cells$, is transplantation of the pancreas; however, this treatment is limited by issues such as the lack of donors for islet transplantation and immune rejection. As an alternative approach, stem cell therapy has been used as a new tool. The present study revealed that bone marrowderived mesenchymal stromal cells (BM-MSCs) could be transdifferentiated into pancreatic cells by the insertion of a key gene for embryonic development of the pancreas, the pancreatic and duodenal homeobox factor 1 (PDX1). To avoid immune rejection associated with xenotransplantation and to develop a new cell-based treatment, BM-MSCs from ${\alpha}$-1,3-galactosyltransferase knockout (GalT KO) pigs were used as the source of the cells. Transfection of the EGFP-hPDX1 gene into GalT KO pig-derived BM-MSCs was performed by electroporation. Cells were evaluated for hPDX1 expression by immunofluorescence and RT-PCR. Transdifferentiation into pancreatic cells was confirmed by morphological transformation, immunofluorescence, and endogenous pPDX1 gene expression. At 3~4 weeks after transduction, cell morphology changed from spindle-like shape to round shape, similar to that observed in cuboidal epithelium expressing EGFP. Results of RT-PCR confirmed the expression of both exogenous hPDX1 and endogenous pPDX1. Therefore, GalT KO pig-derived BM-MSCs transdifferentiated into pancreatic cells by transfection of hPDX1. The present results are indicative of the therapeutic potential of PDX1-expressing GalT KO pig-derived BM-MSCs in ${\beta}-cell$ replacement. This potential needs to be explored further by using in vivo studies to confirm these findings.

One interesting parasitic forming fungus, being grown on the eggs of Phallus impudicus was collected from Mulchajoreum and on woods of Saryeoni in Jeju island. This taxon identified as a Podostroma solmsii (E. Fisch.) S. Imai f. octospora Yoshim. Doi (Hyporeaceae) based on morphological characteristics. According to the interpretation of Doi(1978), this taxon hsving the stipitate, genus Podostroma, family Hypocreaceae, Hypocreales, Ascomycota was identified as Podostroma solmsi f. octospora and its korean common name designated by authors. This species is characterized in having the fusiforme to ellipsoidal, unicellular and warted ascospores without septate and with blunt apiculus at each end and mycoparasitic habitat. Although there is some mycologists suggest that this taxon having above characters needs to be derived from Hypomyces. But authors are primarily going to record this species as a named "Podostroma solmsii (E. Fisch.) S. Imai f. octospora Yoshim. Doi" for the fungus flora of Korea. In a future, it is need in detail to compare their DNA sequencing data on the type species and some related species.
