최근 무선랜 기반 실내 측위시스템을 활용하는 위치정보 서비스가 주목을 받고 있다. 기존 측위 방식에서는 주로 삼각측량 기법에 의존하여 사용자 단말의 위치를 측정하고 있으나, 실내 벽 등의 장애물로 인하여 정확한 측위가 어려울 뿐만 아니라 측위 오차가 크다는 문제점이 있다. 본 논문에서는 무선랜 기반 실내 측위시스템에서 방(room) 등의 블록(block) 단위로 사용자의 위치를 측정하는 방법을 제시한다. 실험 결과, 제안 방식은 기존 방식에 비해 측위 오차를 50% 이상 감소시킬 수 있음을 확인하였다.

Liao River with the largest basin area in the northeastern part of China has constructed huge floodplain along the lower reach. Especially a vast marsh was developed around estuaries and coastline near Liaodong Bay. The marsh was called as Yotaek(or Liaoze) before the modern time, which is meaningful for understanding human life since prehistorian times. By the analysis of historical documents and geomorphic data, it can be assumed that the height of Yotaek of landward boundary reached 20~30m from Heishan to Liaoyang during Han dynasty. The shoreline of 7,000 yr BP is estimated to coincide with the contour line between 20m and 30m at present. And the ancient shoreline during Christ era indicates 10m.a.s.l., which is corresponding to the seaside boundary of the Yotaek. The shoreline of Liaodong Bay was progressed seaward 30km/ka during 1000~1100 AD, while 10~40km/ka during late 19 century ~ early 20 century.

Investors have increasingly become interested in macroeconomic antecedents in order to better understand the investment environment and estimate the scope of profitable investment in equity markets. This study endeavors to examine the interdependency between the macroeconomic antecedents (international oil price (COP), Domestic gold price (GP), Rupee-dollar exchange rates (ER), Real interest rates (RIR), consumer price indices (CPI)), and the BSE Sensex and Nifty 50 index return. The data is converted into a natural logarithm for keeping it normal as well as for reducing the problem of heteroscedasticity. Monthly time series data from January 1992 to July 2019 is extracted from the Reserve Bank of India database with the application of financial Econometrics. Breusch-Godfrey serial correlation LM test for removal of autocorrelation, Breusch-Pagan-Godfrey test for removal of heteroscedasticity, Cointegration test and VECM test for testing cointegration between macroeconomic factors and market returns,] are employed to fit regression model. The Indian market returns are stable and positive but show intense volatility. When the series is stationary after the first difference, heteroskedasticity and serial correlation are not present. Different forecast accuracy measures point out macroeconomics can forecast future market returns of the Indian stock market. The step-by-step econometric tests show the long-run affiliation among macroeconomic antecedents.

This article compares the concepts of divine incarnation as expounded in Daesoon Thought and in Christianity and questions the essence of the divinity in both traditions. In Daesoon Thought, The Supreme God, Sangje, saw major disorganization leading to extreme violence and doom and decided to incarnate on earth under the human form of Kang Jeungsan (1871-1909). Then the living God taught the solution to human suffering through the revelations he sent in 1917 to Jo Cheol-Je, or Jo Jeongsan (1895-1958) and the revelations were passed on to Dojeon Park Wudang who in 1969 founded Daesoon Thought. In Christianity, God incarnated in his son, Jesus Christ, who allowed for the radical transformation of the condition of man through his physical sacrifice. Daesoon differs in that Sangje did not offer himself as sacrifice when he came on earth but reorganized the world and taught how to apply benevolence to establish the Earthly Paradise. The affirmation that Daesoon Jinrihoe is both monotheistic and polytheistic is then analyzed. If the concept of monotheism seems to differ vastly between the two traditions, it appears that biblical monotheism is itself relatively young in the history of world religions so that Christianity has ancient roots germane to those of Daesoon Jinrihoe. The article concludes on the originality of this religion: though it is built on Daoism, Buddhism and Confucianism, it has transformed their vision of the deity and of its message in a most convincing manner.

Crime committed by civilians and criminals using legal and illegal firearms and conversion of legal firearms into illegal ones has become a common practice around the world. As a result, policies to control civilian gun ownership have been debated in several countries. The issue arose because the linkages between firearm-related mortality, weapon accessibility, and violent crime data can imply diverse options for addressing criminality. In this paper, we have projected a mathematical model in terms of the Caputo fractional derivative to address the issues viz. input of legal guns, crime committed by legal and illegal guns, and strict government policies to monitor the license of legal guns, strict action against violent crime. The boundedness, existence and uniqueness of solutions and the stability of points of equilibrium are examined. It is observed that violent crime increases with the increase of crime committed by illegal guns, crime committed by legal guns and, decreases with the increase of legal guns, the deterrent effect of civilian gun ownership, and action of law against crime. Further, legal guns increase with the increase of the limitation of trade of illegal guns and decrease with the increase of conversion of legal guns into illegal guns and increase of the growth rate of illegal guns. Again, as crime is committed by legal guns also, the policy of illegal gun control does not assure a crime-free society. Weak gun control can lead to a society with less crime. Theoretical aspects are numerically verified in the present work.

Competition assures improved products and services to meet customers' needs. The soundness of a firm's financial health is crucial for the country's economic well-being. Distressed companies cause investor panic, which has a knock-on effect on the economy and leads to a deterioration in the image and value of the companies. This paper aims to empirically investigate the influence of competition on financial distress (FD) in the healthcare industry using the Altman Zscore values as the proxy for FD. This study uses secondary data from ten healthcare companies operating in India between 2016 and 2020. The study's findings indicate a significant negative relation with the exogenous variables of the study, implying that a higher level of competition enhances a firm's FD or adversely affects financial health. The main implication of the study is two-pronged. Firstly, the firms' managers and decision-makers need not worry about competition as a deterrent to stability. Secondly, the policymakers need not be concerned that high competition may lead to financial stress for the firms. Therefore, this paper concludes that competition is good for firms operating in India.

This study was about developing a diagnostic assessment tool for the health of Baptist Church. To enable this, the definition of healthy Baptist churches and health factors was examined, diagnostic questions by church health factors was developed. Literature review and research of Delphi were used for research methods. Based on the quarter sampling method, the main survey was conducted on 395 people about factor analysis and needs analysis. Through this study, a healthy Baptist church is defined as a community of believers who glorify God by performing the functions of the church well, having the attributes of the church and the identity of the Baptist church as a body member of Christ. Factors of the healthy Baptist churches are community, loyalty of function, identity of Baptist church, and the essential qualities of the church. It was confirmed that there are 17 factors such as community of faith, worship, priesthood of all believers, and apostolicity. For measuring healthy Baptist Church, it consists of 199 diagnostic assessment questionnaires which can be reduced to 53 or 23 condensed diagnostic assessment questionnaires.

The Rothschild family in the UK and the Rockefeller in the USA installed a number of private organization with which they could exert their influence on the world, recruited world renowned figured and spread out their arguments via global visual media worldwide. Their ultimate goal was to reshuffle the world in a new global order. They attempted to persuade people to accept their messages by reiterating them via their visual media. They deliver their own value of existence, efficiency and future convenience via their visual media regarding politics, economics and religion. If such is seen in a Christian perspective, they replace the place and existence of God with their own power and attempt to reorganize the world in a new global order. Their desire seems to be that of Anti-Christ, i.e. the Satan in the Bible. This study attempts to reveal that reality of visual media is fictitious from the Christian perspective.

The Philippines was colonized by Spain for about centuries, from 1521 to 1898, and ruled by America for around four decades, from 1899 to 1946. After recovering from the Second World War, the government started to harness human labor as export itself. In the present time the overseas Filipinos keep the economy afloat with their steady transfer of money to relatives and dependents. Through the art works, the issue which Filipinos were exploited and exported by its government has been reflected as the various allegories. As Filipinos traditionally follow and keep Catholic belief, themes of Christ's sacrifice has allegorically been represented as salvation, struggle, suppression, and emancipation of people. Through the allegory, we can interpret both the intrinsic and superficial texts. Also we can identity certain modes of the visuality of allegory in selected works from Philippine art history that in their complex mediations materialize the people and dignity of their predicament and their prevailing. Philippine art can be divided as three different features: passion, vagrancy, and mass formation. The passion stage was depicted as deep structure of Christian thought and devotional feeling, harsh capitalist system. In the pictures of vagrancy, under the regime of Ferdinand Marcos, the themes of drift, deprivation, and homelessness are reckoned through the images of pictures. The stories represented with allegory have been played an important role to bring local issues up as national ones. Those stages take us to the processes of mass formation or the depiction of the people as a moment in the totality of force. The allegorical sign refers to another sign that precedes it, but with which it will never able to coincide reach back to a previous stage and in this constant attempt at return incorporates a structural distance from its origin. The true people's art is one that radically generates transformative technologies and techniques so that it irrevocably breaks the plane of "art". In the painting, the truth is represented by functioning as foundation of a rhetoric of the image. And at this axis, the passional, the vagrant, and the mass formation tend to come together because they render the form of contingency that must be suffered and hopefully surpassed, a Filipino subjectivity that must be stitched in time.
