Purpose: To report a case of bilateral acute myopia and angle-closure with ciliochoroidal detachment in Vogt-Koyanagi-Harada (VKH) syndrome. Case summary: A 43-year-old Korean woman diagnosed with VKH syndrome underwent intravenous methylprednisolone steroid pulse treatment. After oral medication was given for 2 days, the anterior chambers became shallow in both eyes. Intraocular pressure (IOP) increased to 25 mm Hg in the right eye and 23 mm Hg in the left eye. Subretinal fluid increased and visual acuity decreased with myopic shift in both eyes. IOP did not decrease despite maximum tolerated medical therapy. Ultrasound biomicroscopy (UBM) revealed that ciliochoroidal effusion caused forward displacement of the lens-iris diaphragm, which resulted in anterior chamber shallowing and angle closure in both eyes. The patient was treated with cycloplegic eyedrops and intravenous steroid pulse therapy. After intravenous steroid pulse treatment was given for 2 days, the anterior chambers became deep in both eyes. IOP reduced to 13 mm Hg and 14 mm Hg in the right and left eye respectively. Visual acuity increased with normalization of myopic shift. UBM revealed that the ciliochoroidal effusion had resolved in both eyes. J Korean Ophthalmol Soc 2012;53(8):1194-1199

Introduction: There are few reports on tooth eruption through Bio-Oss grafts. To our knowledge, there are no reports on whether teeth can erupt normally through the grafts. The aim of this study was to examine the effect of Bio-Oss grafts on tooth eruption in a canine model. Materials and Methods: In five 10-week-old dogs, the deciduous third mandibular molars in one jaw quadrant of each animal were extracted and the fresh extraction sockets were then filled with Bio-Oss particles (experimental side). No such treatments were performed on the contralateral side (control side). A clinical and radiological evaluation was carried out every other week to evaluate the eruption level of the permanent third mandibular premolars and compare the eruption levels between the two sides. Results: At week 4 after the experiment, the permanent third premolars began to erupt on both sides. At week 12, the crown of the permanent third premolar emerged from the gingiva on both sides. At week 20, the permanent third premolars on both sides erupted enough to occlude the opposing teeth. No significant differences were found between the control and experimental sides in terms of the eruption speed of the permanent third molars. Conclusion: These findings demonstrate that the grafting of Bio-Oss particles into the alveolar bone defects does not affect tooth eruption.

정보검색과정에서 용어의 일관성을 유지하기 위해, 시소러스에서 용어의 의미를 명확하게 제시하는 것이 필요하다. 이에 대부분 시소러스는 기본관계나 범위주기를 이용하여 용어의 의미를 제시하여 왔으나, 최근 내용과 형식에 있어서 표준화된 정의를 포함하는 시소러스가 제안되어 왔다. 이 연구는 표준화된 정의를 작성함과 동시에 그러한 과정에서 사용한 정의모델의 내용에서 관계를 추출하고, 이들 표준정의와 추출된 관계를 기존의 시소러스에 통합하거나 대체하여 확장된 시소러스를 구축해 봄으로써, 시소러스가 더욱 발전할 수 있는 가능성을 고찰하였다. To maintain consistency of terms in information retrieval process, it is necessary to present the meaning of terms definitely in thesaurus. Therefore, most of thesauri has presented meaning of terms through basic relationships or scope notes. But. thesaurus including standardized definitions in contents and form has been proposed lately. This study was performed to make standardized definitions and extract relationships in contents of defining models. Also, expanded thesaurus was constructed being integrated and replaced standardized definitions and extracted relationships into the existing thesaurus. As the result. this study has shown a possibility for further development of thesaurus.

Due to the advent of knowledge-based society and digital environment, libraries especially national libraries are undergoing a transformation and the new concepts, processes and tools for collection development as the heart of libraries are evolving. The purpose of this paper is to propose the direction of hybrid resources development for ensuring sustainable collection and preservation of resources in national libraries. Accordingly, this paper looks about a transformation of national libraries and collection development, and investigates the coverage of national collections based positioning of national libraries through performance indicators in standard, definitions, purposes and missions. It also proposes legal deposit methods of digital resources through the law related library and investigates archiving method of online digital resources including hybrid collection development system in national libraries.

지금까지 대부분의 시소러스에서 용어의 의미는 주로 관계나 범위주기를 통해 간접적으로 제시되어 왔다. 그러나 시소러스가 양적으로 팽창해짐에 따라, 이들을 통해 용어의 의미를 명확히 파악하는 것이 점차 어렵게 되었다. 이에 일부 시소러스는 사전의 정의를 함께 수록하기도 하였지만, 그 내용이나 형식이 만족스럽지 않은 것으로 인식되어 왔다. 이 연구는 용어의 의미를 제공하는 정의의 필요성을 토대로 표준화된 정의를 시소러스에 통합해 봄으로써, 시소러스가 더욱 발전할 수 있는 가능성을 제시하였다. Until now, the meaning of terms in most of thesauri has been indirectly presented through relationships and scope notes. However, as thesaurus has been expanded quantitatively, it has become difficult to understand meaning of terms clearly using those relationships and scope notes. Though some thesauri take the form of 'thesaurus dictionary' in order to present the meaning of descriptors, the contents and forms of provided definitions are not satisfying. As standardized definitions of terms integrate into thesaurus on the basis of necessity of definitions providing meaning of terms, this study has shown a possibility for further development of thesaurus.
