As a new tool for finding out databases through which we can get some knowledges on our fields, no matter what fields they are, internet search engine is introduced on the internet. As far as this search engine is concerned, it is needless to say that internet is always being used with the help of these search engines. How far we can make use of these search engines is the only decision-making factor of who the scholars are and what the scholars are. In other words, there's no way for the scholars to reach the academic goals without efficient using of the Internet in which we can find over 1,500 search engines. Besides these scholars, as a matter of fact, those group of people who are businessmen,students,politicians and etc., also need this internet search engines, because there are lots of appropriate informations on it. As for Malaysian search engines, we just can get to know that there aren't many search engines like western search engines yet. But it is rather desirable for us to say that number of the Malaysian search engines are increasing year by year, In my writings here you could imagine how wide the scope of the Malaysian internet world covers with the help of increasing number of Malaysian search engines for the New Millennium. And of course, you could notice that there are unexpectable Malaysian websites with which not a few students of ours can learn how to speak, read, and write In Malay language. In this short essay I am also trying t() let you have a look at real samples of the result of being retrieved by these Malay search engines on which we are just focusing as much as possible. Nevertheless, there are still much space enough to be filled with different style of databases and informations in it. As a result, 1 can't help saying that this small essay is just regarded as a starting point in this Malay search engine field. 1 hope there must be a succession of this essay in the near future, even though we don't know who it could be yet.

Estrogen이 가토의 이개변형에 미치는 영향

오경,김정희,김정태,김석권 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.1

Congenital auricular deformities such as lop ear, cup ear, prominent ear, and Stahl's ear can be corrected nonsurgically in the early neonatal period(first week after birth) obtaining satisfactory results. Auricular cartilage consists of chondrocytes and intercellular materials that are mainly assembled from collagen, elastin, and a proteoglycan aggergate. Cartilageelasticity is dependent upon the concentration of the proteoglycan aggregate. Hyaluronic acid, which is a constituent of proteoglycan aggregate and is increased by estrogens, has an important play on disconnecting the proteoglycan aggregate. So the increased estrogen results in the lack of elasticity. The circulating levels of free estradiol are higher during the first 72 hours after birth and decreases thereafter, so the ear is soft and easily malleable in this early neonatal period. In this study, we have applied aluminium splint(90 degree-angulated, 180 degree-angulated, and rolled) on rabbit ear. All of the rabbit was divided into 3 groups containing 3 types of deformities. In group 1, estrogen was applied to the deformed ear with regional injection to the perichondrium of auricular cartilage. In group 2. estrogen was applied topically with ointment. In group 3, as control group, saline was injected to the perichondrium. Four weeks later, in group 2, the shape of the deformed rabbit ear was maintained, and did not return to its original shape even after splint removal. From these results, we concluded that estrogen ointment could be tried as adjunctive therapeutic modalities to the nonsurgical treatment of the congenital auricular deformities.

초등영어교육에 있어서의 효율적인 발음지도

고경석 仁川敎育大學校 初等敎育硏究所 1998 교육논총 Vol.15 No.-

The purpose of this paper is to introduce both theoretical and practical aspects of English pronunciation teaching to learners and teachers of elementary school English. The acquisition of a good pronunciation in the target language is commonly held to be the most difficult tasks in language teaching. The major part of this study is devoted to techniques of teaching pronunciation - articulation, stress and intonation - at the level of elementary school English. We have had the experience when listening to a foreigner speaking our language of having great difficulty in understanding what he/she is trying to express. Pronunciation is probably the most neglected aspect of English teaching. Work on pronunciation is important for two main reasons: to help the students understand the spoken English to hear, and to help them make their own speech more comprehensible and meaningful to others. The various elements are considered in this paper: individual sounds, word stress, sounds in connected speech, rhythm and stress in utterances, and intonation. Pronunciation should be an integral part of an English teaching program from the early stages, just as the teaching of structures and vocabularies.

이중에너지 방사선 흡수계측법을 이용한 성인 남녀의 장골 및 경골의 골밀도에 관한 연구

조용석,김경원,이경호,박현진,서상수,오상엽 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.3

Purpose : The aim of this study was to evaluate the bone mineral density of iliac and tibial bone which are frequently selected as autogenic bone graft donor sites, and to evaluate the efficiency of this method as a guideline for the selection of bone graft donor site. Materials and Methods : In this study 61 male and 70 female volunteers at Chungbuk National University Hospital were involved between Jan. 1998 to Sept. 1999. We measured bone mineral density of the iliac and the tibial bone using dual energy X-ray absorptiometry. We evaluated the data using the SAS system for Windows and bone mineral density of the lumbar was used for control. Results : Age showed the highest correlation in correlation matrix between physical and bone variables. Height and weight showed lower correlation of linear increment. In man, the change of bone density according to age demonstrated linear decrease irrespective of the lumbar, ilium, and tibia. In woman, the change of bone density according to age showed cubic form, which increased in the third and forth decade. So it had a peak bone mass on about 35 year-old, thereafter, the change of bone density slowly decreased until 50 year-old, but it rapidly decreased after 50 year-old and it slowly decreased again after 65 year-old. Both in all subjects and subject with osteoporosis, the change of bone mineral density according to age showed statistically significant decrease in lumbar and tibia, but ilium was irrespective. Conclusion : In patients of aged or with osteoporosis, ilium demonstrated less tendency of decrease in bone mineral density than tibla. So this preliminary study suggested that ilium seemed better donor site for autogenic bone graft than tibia.

고차원 색인 구조를 위한 벌크 삽입

복경수,송석일,유재수 충북대학교 컴퓨터정보통신 연구소 2001 컴퓨터정보통신연구 Vol.9 No.1

최근 고차원 데이터를 위한 다양한 색인 구조에 대한 연구가 진행되어 왔다. 지리정보 시스템, 내용기반 이미지 검색 등과 같은 응용분야에서는 일반적으로 색인 구성 후 추가적으로 발생하는 데이터 역시 대량으로 삽입되는 경우가 빈번하다. 대량의 데이터를 하나씩 삽입하게 되면 삽입하기 위해 소요되는 시간과 검색 성능의 저하를 발생시킨다. 이러한 문제점을 해결하고자 다양한 벌크 삽입 기법들이 제시되었다. 벌크 삽입의 목적은 삽입 시간을 단축시키고 검색 성능을 향상시키는 것이다. 그러나 기존의 벌크 삽입 기법들은 한쪽에 군집된 데이터만을 고려하거나 또는 기존의 색인 구조에 존재하는 MBR을 고려하지 않고 있다. 본 논문에서는 일반적인 경우에도 좋은 검색 성능을 보장하고 데이터의 삽입으로 MBR들간의 겹침을 최소화하기 위한 새로운 벌크 삽입 알고리즘을 제안한다. Recently, various high-dimensional index structures have been proposed. Generally, in the applications such as geographic information System, content-based image retrieval and so on, large amount of data are presented to be inserted into existing index structures. Inserting each data item one bye one is very inefficient in terms of insertion time and query performance. In that reason various bulk insertion techniques are proposed to solve the problem. The purpose of bulk insertion speeds up insertion time and improves query performance. However the existing methods perform only for highly skewed data and do not consider existing MBRs of index structures when data objects are inserted. In this paper, we design a bulk insertion algorithm that performs well for general case and minimizes overlap between newly inserted objects and existing MBRs.

Carry Lookahead Adder의 면적 감소 방안에 관한 연구

고행석,장경선 충남대학교 산업기술연구소 2003 산업기술연구논문집 Vol.18 No.1

Though, Carry Lookahead Adder is widely used since it is fast, it takes large area. This paper presents a method to enhance the area-time product by replacing a part of lookahead carry propagations with ripple carry propagations. The proposed scheme reduces the area by 20% while it increases one or two levels of gate delays regardless of the number of bits. With experiments, we noticed that the proposed method is effective especially when it is implemented on a fine-grained FPGA with mux-based structure.

이 논문에서는 서비스의 흐름의 표현을 보다 쉽게 하기 위해 ARS 서비스 내용을 사용자와 ARS 서비스간의 동작 단위인 트랜잭션으로 나누고, 모든 트랜잭션을 표현하기 위해 트랜잭션을 분석하여 일반화한 처리노드를 제시하였다. 이 처리노드를 통한 서비스의 기술 및 실행을 할 수 있는 개발 환경인 ARS 자동생성기 모델을 제시하고 구현하였다. ARS 자동 생성기는 서비스의 기술을 GUI(Graphic User Interface)를 통해 할 수 있는 그래픽 에디터와 서비스 기술 정보를 이용하여 실제 동작을 수행하며 정보처리 및 데이터관리를 위한 응용프로그램의 인터페이스를 지원하는 ARS 엔진으로 구분된다. 이 논문에서 제시한 처리노드를 이용함으로 서비스의 흐름을 보다 쉽게 기술할 수 있다. ARS services could be presented by a series of transactions which are the units representing the interaction between ARS and user. In this paper, we propose a model for a processing node which represents the operation of a generalized transaction. We also implement an ARS generation tool that performs an ARS service with the information of processing nodes. The ARS generation tool consists of three components: the Operation Database, the Engine, and the Application Interface. The information for the processing nodes is stored in the Operation Database. ARS Engine is responsible for the middleware operations. It proceeds the processing nodes. The concept of processing node makes it convenient to describe the operation of an application ARS.
