송명규 한국지역개발학회 1990 韓國地域開發學會誌 Vol.2 No.1
The main purpose of this paper is to establish a new theoretical model for explaining residential income segregation phenomenon taking place in most large cities. This model is based on Tiebout model, which was suggested for efficient local public goods allocation by Charls Tiebout in 1956, and hedonic price theory of housing. Till now, various theories have been proposed under the purpose of explaining residential income segregation. But the model established in this paper is expected to be more analytical and general at least in case of Korea, which has nation-wide uniform local public finance structure from the point of local tax rate, than any other theory that is believed to be more compatible with Western societies.

"풀어놓는 삶 , 살리는 풍성함" : 산안마을 의생활부를 사례로
송명규 한국지역사회개발학회 1999 地域社會開發硏究 Vol.24 No.2
In the face of the present global ecological crisis, what should we do to overcome it? Should we abandon material abundance entirely and live in an extremely frugal society? Is there no way to have both material abundance and ecological soundness? This paper examines one possibility. That is to live in no possessiveness. If we take out individual possessions and use them collectively, we could live in material abundance, minimizing resource use, waste matters disposal, and harmful ecological impact. Taking out possessions means not collective ownership but disownership. This paper introduces the way of clothes management of 'San-An Village' as a go examplary model.

한국어 숫자음의 음운변화 및 화자 발성특성을 고려한 연결숫자 인식의 성능향상
송명규,김형순 한국음향학회 2002 韓國音響學會誌 Vol.21 No.4
Each Korean digit is composed of only a syllable, so recognizers as well as Korean often have difficulty in recognizing it. When digit strings are pronounced, the original pronunciation of each digit is largely changed due to the co-articulation effect. In addition to these problems, the distortion caused by various channels and noises degrades the recognition performance of Korean connected digit string. This paper dealt with some techniques to improve recognition performance of it, which include defining a set of PLUs by considering phonemic variations in Korean digit and constructing a recognizer to handle speakers various speaking styles. In the speaker-independent connected digit recognition experiments using telephone speech, the proposed techniques with 1-Gaussian/state gave string accuracy of 83.2%, i. e., 7.2% error rate reduction relative to baseline system. With 11-Gaussians/state, we achieved the highest string accuracy of 91.8%, i. e., 4.7% error rate reduction. 한국어 숫자는 모두 단음절로 이루어져 있으며, 연속적으로 발음될 때 인접 숫자들의 상호조음현상에 의해 각 숫자의 고유 발음이 변화하고, 또한 그 숫자들의 경계도 모호해지는 문제점이 있다. 이러한 문제점들과 더불어 배경잡음이나 채널에 의한 왜곡에 따른 문제점들로 인해 한국어 연결숫자의 인식 성능은 만족스럽지 못한 것이 현실이다. 본 논문에서는 연결숫자의 인식성능 향상을 위해서 한국어 숫자들의 음운변화를 고려하여 유사음소 (phonelike units: PLUs)군을 정의하고, 사용자의 여러 가지 발성형태에 따른 다양한 음운 현상의 변화를 흡수할 수 있도록 인식 시스템을 구성하는 방식을 검토하였다. 전화망 4연숫자를 이용한 화자독립 인식 실험을 수행한 결과 제안된 방법의 숫자열 인식률은 상태당 믹스쳐 (mixture) 개수가 1인 경우 83.2%로, 기준 시스템 (baseline)에 대한 오류감소률이 7.2%였고 가장 높은 성능을 나타낸 믹스쳐 개수가 11인 경우 숫자열 인식률은 91.8% 오류감소율은 4.7%였다.

포도원에서 식초 종류에 따른 초파리과(Drosophilidae) 유인효과 및 벗초파리(Drosophila suzukii)의 발생시기
송명규,이재웅,이석호,김승덕,박재성,김길하 한국응용곤충학회 2017 한국응용곤충학회 학술대회논문집 Vol.2017 No.04
벗초파리(Drosophila suzukii)는 아시아가 원산인 파리목 초파리과의 해충이다. 국내에서의 피해사례는 보고되지 않았지만 북미와 유럽에서는 블루베리, 체리, 포도 등의 작물에 많은 피해를 입히는 중요한 해충으로, 알자스의 포도 수확량이 15% 정도 감소되었다는 피해사례가 보고되었다. 미국, 뉴질랜드 등에 수출을 할 때 검역 해충으로 수출포도단지 및 선과장 등에서의 발생이 민감한 해충이다. 본 연구는 효율적인 초파리 모니터링을 위해 식초의 종류, 식초량에 따른 유인량을 알아보고, 수출포도단지에서의 벗초파리 발생시기를 알아보고자 수행하였다. 사과 식초 30, 70, 100ml를 넣고 초파리 유인량을 비교한 결과 유인량에는 차이가 없었다. 양조식초, 현미식초, 사과식초, 백포도식초, 사과식초+와인(5:5) 처리 결과 사과식초+와인(5:5)에서 유인량이 가장 많았다. 수출포도단지 내 재배포장에서 조사한 결과 노랑초파리는 8월에도 발견되었으나, 벗초파리는 9월 중순부터 발견되었다.

Objectives : The aim of this meta-analysis was to draw overall conclusions on the correlation between the organizational effectiveness (OE) of healthcare employees and related factors by summarizing recent studies and to provide a baseline for future research. Methods : A literature search for original articles published from 2005 to 2014 including doctoral theses and KCI journal articles was done in KERIS’ RISS, etc. in a systematic manner. From 77 studies which met the inclusion criteria 190 effect sizes (ESs) were calculated for the analysis. A meta-analysis was done with CMA 3 (Biostat company, USA). Results : The overall ES was moderate for all, positively and negatively related factors. For all related factors, job characteristics, group-leader relations, personal and organizational characteristics had a moderate ES. The ES for work experiences was small. Conclusions : Although the results of this study were meaningful it is necessary to perform follow-up analyses (1) based on a longer data period and more articles, (2) including moderating variables with higher explanatory power and (3) adopting a study model with more specific and simplified variables.

In this paper, We study Network threats and security methods. There are four types threats, Interruption, Interception, Modification, Masquerade. We explain these types simply. To overcome, We use Encryption Algorithms. Also there are the simple studies of these algorithms. There are too many types Networks. Therefore the optimal method for a Network must be found. This paper is for that goal. Key Words : Network threat, Security, Encryption Algorithm , Cipher

Recently the technology of communication has been changed very fastly. This change has serval characteristics. The first is high speed (bandwidth) The second is globalization. And the third is to be network. In this paper, we know the relationship of the communication and network Basicaly the communication technology is adapted only two point.( Source and Destination ). But the network technology is related to all points that want to transmit some information each others. Therefore the routing and switching are very important in Network. All of this technology can be presented by the protocol
