The purpose of this paper is to visualize the housing market dynamics with ESDA (Exploratory Spatial Data Analysis) using MATLAB toolbox, in terms of the modeling housing market dynamics in the Busan Metropolitan City. The data are used the real housing price transaction records in Busan from the first quarter of 2006 to the second quarter of 2009. Hedonic house price model, which is not reflecting spatial autocorrelation, has been a powerful tool in understanding housing market dynamics in urban housing economics. This study considers spatial autocorrelation in order to improve the traditional hedonic model which is based on OLS(Ordinary Least Squares) method. The study is, also, investigated the comparison in terms of $R^2$, Sigma Square(${\sigma}^2$), Likelihood(LR) among spatial econometrics models such as SAR(Spatial Autoregressive Models), SEM(Spatial Errors Models), and SAC(General Spatial Models). The major finding of the study is that the SAR, SEM, SAC are far better than the traditional OLS model, considering the various indicators. In addition, the SEM and the SAC are superior to the SAR.

In this study, the relationship between the organizational characteristics of police officers and the level of post-traumatic stress disorder in the comparative analysis was to check for post-traumatic stress disorder, according to the organizational characteristics affect. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. The department in post-traumatic stress disorder level, a significant difference was found. It was more likely to be exposed to a traumatic experience if who is working in the front-line department. Post-traumatic stress disorder according to the work unit, a significant difference was found. The level of Post-traumatic stress disorder in outside job unit officers was higher than that of desk job unit offcers. Post-traumatic stress disorder according to the rank and duration of employment and the administrative district level, a significant difference was not found.

It is necessary to develop a new location model to support the application of smart technology and confluence in the 4th industrial revolution era. In this study, we propose 'network-type industrial complex' as a method to link several industrial integrated spaces which are dispersed in an area. As a result of conducting a survey of companies in order to develop a new location model, about 89% of companies recognized the necessity of network-type industrial complex. As a condition for activation of the industrial complex, 'complementary function formation', and 'convenience of nodular transportation' were selected. It is expected that it will be possible to supply low-cost, high-efficiency industrial complexes through opening and linking with urban space and infrastructure sharing.

Establishments of wholesale of recycling materials are located in the region where an amount of recyclable wastes generated as artery industry developed and the region of rather many population. And they are located not in underpopulated area as noxious facilities, but located in the non-residential area of many population regions in the whole country. Also, establishments of recycling of metal wastes and scrap, and non-metal wastes and scrap are mainly located in the peripheral region of metropolitan cities, regional centered cities, and adjacent regions of industrial area, because of high coefficient of localization, and agglomerated effects of production. The factor influencing the location of recycling industries is deeply connected with the location of wholesale of recycling materials, and thus, the transportation costs to carry recycling materials from supplied regions to plants are important but population is not so important.

Impact of Korea train express (KTX) on the regional economy in Korea has been studied by many researchers. Current research is limited in the lack of quantitative research using a statistical model to study the effect of KTX on regional economy. This paper analyses the influence of KTX to the household final consumption expenditure, which is one of important regional economic index, using spatial panel regression model. The spatial structure is introduced through spatial autocorrelation matrix using adjacency of KTX connection. The result shows a significant effect of Korea train express on the regional economy.

우리나라의 소득분배문제에 대해서 종래에는 적어도 1980년대 이후 개선되고 있으며, 국제비교에서도 다른 나라에 비해 결코 나쁘지 않다는 평가가 주류를 이루고 있었으나, 최근에는 그에 대한 반론이 만만치 않게 전개되고 있다. 본고에서는 "도시가계연보"의 원자료를 이용한 새로운 추계를 시도하여 1980년대의 소득분배가 지금까지의 통설처럼 그렇게 많이 개선된 것은 아니라는 결과를 제시하였다. 마찬가지로 일부의 반론처럼 1980년대의 소득분배가 실제로 악화되었다는 주장도 과장일 가능성이 크다는 점도 지적하였다. 단, 근로소득의 분배가 개선되고 있음은 분명하나 토지나 주식 등에 의한 불로소득까지 포함하면 결과는 크게 달라질 수 있다. 이 문제의 검증은 아직 끝난 것이 아니며, 올바른 결론에 도달하기 위해서는 앞으로 보다 많은 자료들이 발굴, 분석되어야 할 것이다. 한국의 자산분배에 대해서는 지금까지 자료가 별로 없어서 논의 자체가 어려운 상태였다. 최근 대우경제연구소의 패널 자료를 분석해본 결과, 한국의 부의 분배는 지금까지 알려진 것보다 훨씬 더 불평등하며, 특히 토지 등 실물자산의 불평등이 심각한 것으로 나타났다. 한편 한국의 빈곤은 많이 줄어든 것이 사실이며, 다른 후진국과 비교해서 빈곤 축소에 큰 성과를 거둔 것으로 평가된다. 본고에서 좀더 현실적인 최저생계비를 가정하여 분석해본 결과 한국의 빈곤은 물론 많이 줄어들었지만 아직 상당히 남아 있으며, 빈곤의 크기 자체(빈곤 갭)는 그다지 크지 않은 것으로 나타났다. 본고에서는 이러한 연구결과에 기초해서 우리나라의 분배문제에 대한 평가를 내리고 효율성과 형평성의 조화라는 관점에서 정책의 기본방향을 설정하였으며, 조세정책가 재벌정책에 초점을 맞추어서 정책방향을 논의하였다. 분배정의 관점에서, 우리나라의 세제는 직접세 비중을 높이고, 종합토지세, 상속 증여세 등 재산관련 세제의 기능을 강화하며, 근로자와 비근로자간 세부담의 형평성을 제고하는 방향으로 개편되어야 한다. 그리고 재별의 소유분산 자체보다는 재벌이 자행할 수 있는 경제적 부조리를 막기 위한 장치를 강화하는 것이 중요하다. 상속 증여세제 등의 강화나 기업경영의 투명성을 제고하기 위한 감시장치가 강화되어야 할 것이다. 특히 자유주의자가 강조하는 '정당한 권리의 원칙'으로서 '부정의의 시정'의 원칙이 보다 적극적으로 반영될 수 있어야 하며, 이러한 주장 자체가 시장 메커니즘을 옹호하는 진정한 자유주의 원칙에 입각하고 있다는 점이 강조되어야 할 것이다.

A test on the significance of style factors which were revealed to be significant in U.S. and U.K. literature is conducted in this study using appraisal-based returns of offices in Korea. Region, size (appraisal value), value-growth propensity (yield gain gap) and leasing conditions (the number of tenants, the length of average leased period and the proportion of key tenant) are included in the analysis model as style factors. The empirical result suggests that firstly core region and large size are significant but they increase risk as well as return contrary to general belief, secondly value propensity significantly decreases risk as well as return as it does in U.S. and U.K., finally the number of tenants among leasing conditions decreases risk as well as return but the length of average leased period and the proportion of key tenant are not significant.

Crowdedness management at subway platforms is essential to improve services, including the prevention of train delays and ensuring passenger safety. Establishing effective crowdedness mitigation measures for platforms requires accurate estimation of the congestion level. There are temporal and spatial constraints since crowdedness on subway platforms is assessed at certain locations every 1-2 years by hand counting. However, smart cards generate real-time big data 24 hours a day and could be used in estimating congestion. This study proposes a model based on data from transit cards to estimate crowdedness dynamically. Crowdedness was defined as demand, which can be translated into passengers dynamically moving along a subway network. The trajectory of an individual passenger can be identified through this model. Passenger flow that concentrates or disperses at a platform is also calculated every minute. Lastly, the platform congestion level is estimated based on effective waiting areas for each platform structure.

The purpose of this research is to analyze the characteristics and problems of 'Reading Cheongju' which launched as 'One Book, One City' reading promotion campaign in 2006 and conducted 23 times for the past 15 years. The analysis of the selection criteria of 'one book', 31 selected books, and the activity of reading and discussion shows the strength of continuity and stability of 'Reading Cheongju'. However, the following weaknesses need to be improved on: the inadequate change in book selection criteria, selection of several books according to age groups instead of 'One Book', lack of consistency in themes of selected books, preference for best-sellers and popular works, difficulty in identifying the continuance of individual participation in reading and discussion, librarians' role limited to organizing programs, and lacking in direct participation in discussion and communication, and events and programs only led by Cheongju City Library without any cooperation from community members.
