土地公槪念의 實想과 虛想

이병길 청주대학교 대학원 1991 우암논총 Vol.7 No.-

As the economy has been developed in out country which is too small in territory compared to over population, the demand for the real estate is rapidly increased and this leads to the sudden rise of the real estate price. On accocent of the above consefuences, as the property in come which is generated from the real estate is enbaned highly to the labor income in the weight of gross income, this bringo about the disparity on wealth and poverty. Also this leads to the rise in price and loss of labor will. This study suggests items should be arranged in order to eliminate bad effects generated from the real estate as conclusions.

아파트 住居 環境改善에 관한 硏究 : 黃金 住公아파트와 그린맨션 아파트를 中心으로

李丙吉 대구산업정보대학 1989 논문집 Vol.3 No.-

The importance of the housing role in managing human life was indicated and explanated the process how the Korean housing architecture style had been transformed and improved, develoved. Also the physical, social, political traits of the housing were described. In addition to the above explanation, the traits of apartment residence were summarized in contrast with the those of individual housing. There's described the survey results which has conducted in order to grasp the actual condition and residence environment on the two instance apartment lots selected by option. The disposition of conciousness which had been selected as survey target inhabitants for the apartment environment and public utilities was described. First of all, as the influnce which the residence state has become bigger and bigger, to grasp the inhabitant's disposition of condsciousness for the environment seemed to become important. Also to improve the Quality of residence life enviroment will be contributed to increase national welfare planned by government policy. The characteristic of this thesis is in proposing the new method of satisfying the group who needs the dwelling house. This thesis also demands the govenment to classify house holdo who wants to have dwelling house as various tyrer for example family number, sex, profession, ages, income, taste etc by administrative organization. This classification will be able to make the construction budget cut down and increase the investment efficiency for the public facilities.

점사상 밀도 분석을 위한 L-지표의 적용

이병길,Lee, Byoung-Kil 한국공간정보학회 2008 한국공간정보학회지 Vol.16 No.2

지도좌표를 가진 정보의 통계적 분석은 GIS 중요기능 중 하나로 인정되고 있다. 그 중 가장 기본적인 분석의 하나로 점사상에 대한 밀도분석이 이루어지고 있다. 밀도분석은 일반적으로 라스터 분석의 일부로 간주되고 있으며, 적합한 밀도분석을 위해서는 kernel 반경으로 알려진 검색반경의 결정이 중요한 것으로 알려져 있다. 본 연구에서는 기존 연구 결과에서 검색반경 설정에 유용한 것으로 알려진 L-지표를 이용하여, 비즈니스 GIS 분야에 축적된 점사상의 밀도 분석에 적합한 반경을 추정하고, 추정된 결과를 기반으로 점사상의 특성에 따른 L-지표의 거동을 고찰하였다. 연구결과 점사상이 대상지역의 일부 지역에서 크게 밀집되는 경우에는 L-지표가 대상지역의 크기와 무관하게 일정한 반경에서 극대값을 보이기 때문에 L-지표를 이용하여 검색반경을 설정하는 것이 유용함을 알 수 있었다. 반면, 점사상이 대상지역에 고루 분포하는 경우에는 L-지표의 극대값이 나타나는 반경이 대상지역의 크기에 따라 영향을 받기 때문에 L-지표를 이용하여 검색반경을 설정하는 것이 적합하지 않음을 알 수 있었다. 따라서 L-지표를 이용한 점사상 밀도의 검색반경 설정에는 점사상의 분포특성이 고려되어야 함을 알 수 있었다. Statistical analysis of the coordinate information is regarded as one of the major GIS functions. Among them, one of the most fundamental analysis is density analysis of point features. For analyzing the density appropriately, determining the search radius, kernel radius, has critical importance. In this study, using L-index, known as its usefulness for choosing the kernel radius in previous researches, radius for density analysis of various point features are estimated, and the behavior of L-index is studied based on the estimated results. As results, L-index is not suitable to determine the search radius for the point features that are evenly distributed with small clusters, because the pattern of the L-index is depends on the size of the study area. But for the point features with small number of highly clustered areas, L-index is suitable, because the pattern of the L-index is not affected by the size of study area.

韓國企業 勞使和合에 佛敎 無我 思想의 寄與 可能性 硏究

李丙吉 대구산업정보대학 1999 논문집 Vol.13 No.1

Since the 1987 year, the conflict between labor and management in the korean enterprise has been intensified. On account of the conflict between labor and management, the international competition power of korean enterprise has been lowered. The harmony between labor and management is indispensable needed in order to achieve steady growth of the korean enterprise. The ultimate goal of this study is aimed at utilizing the principle of buddhism philosophy in order to achieve the harmony between labor and management.

Verifing Formation of Area of Influence of Subway Station through Land Value Distribution Analysis – Case Study on Seoul

이병길,이상경 한국측량학회 2016 한국측량학회지 Vol.34 No.4

This research has the purpose to develop a method to evaluate whether station’s area of influence has been formed, and verify formation of the area of influence through empirical analysis of all subway stations in Seoul. First, we created buffers of 100m intervals from 100m to 1000m, based on subway station exits, calculated the average land price of each buffer, and divided station areas of influence into 10 clusters using K-means clustering with the average land prices as values of observation. Subsequently, we have assumed a decreasing price curve from increasing distance from a nearby subway station, estimated a price curve and evaluated whether the area of influence actually exists using regression analysis of each cluster. The 10 area of influence clusters were largely divided into strong, weak, and no area of influence of subway station. The stations where the strong areas of influence are formed are mainly located in center, sub-centers, and local centers; stations where weak and no areas of influence are formed are mostly located in the adjacent areas of center or sub-centers or suburbs.

우리나라 企業의 賃金制度에 관한 硏究

李丙吉 대구산업정보대학 1990 논문집 Vol.4 No.-

The purpose of this consideration is in finding the method of determining wage level is conceded by both employee and employer, whenever spring comes, industry disputes occur which are due to the view of difference on the raise in wages. These disputes result in less which is fatal to our economy on national dimension. This study suggests the productivity wages system which is seemed to eliminate this loss. Nowadays, raise in wages influences a rise in price. The rise in price causes the raise in wages. This is called as the vicious circle. The productivity wages system means that wages should be determined by productivity improvement.

이동통신 시스템을 위한 소스코더와 결합된 채널코딩방법에 의한 영상전송

본 논문에서는 광대역 코드분할 다중접속방식(W-CDMA : Wideband-Code Division Multiple Access)을 이용하는 전력제어된 이동통신 시스템에서 영상전송을 위한 채널모형을 설계하고, 영상 소스 데이터와 결합된 채널 부호화에 대한 설계를 하고 전송성능을 검증하고자 한다. 웨이브릿 변환 알고리즘을 이용하여 각 대역별 중요도에 따라 차등적인 크기의 블록 단위로 세분화하여 독립적으로 부호화 하였고, 영상정보의 전송에러에 대한 감응도를 고려하여 RS(Reed-Solomon)부호화시에 각각의 신호대역에 따라 분리된 RS 부호화율을 적용하여 W-CDMA 페이딩 채널 에러에 대하여 동일한 데이터율로서 더 나은 PSNR 이득을 얻도록 하였다. 또한 Truncated Hybrid Type I ARQ 방식에 의한 재전송과정에서 재전송 프레임간 Combine하여 성능을 향상시킬 수 있는 장점이 있다. 시뮬레이션을 통해 차세대 영상전송 시스템으로서 기존의 독립적인 영상-채널 부호화방식에 비해 무선채녈의 열화에서도 성능의 감소가 크지 않아 효과적인 영상전송 방법임을 알 수 있었다. In this paper, we present the efficient image transmission system using designed source-channel combined coder in W-CDMA mobile communication system. In proposed schemes, we decompose the wavelet transformed hierarchical band-images into some types of different size blocks which have different properties in error sensitivity. The RS(Reed-Solomon) coder with different coding rate is used for each decomposed source blocks which has different importance. In addition, we combine retransmitted error frames in Truncated Hybrid Type I ARQ. The proposed algorithm shows efficient image transmission methods because it is not much degraded in PSNR compared with the existing not combined source-channel coder in erroneous wireless channel.
