Purpose: This study aims to map the spatial distribution of poverty using nighttime light satellite images as a proxy indicator of economic activities and infrastructure distribution in D.I Yogyakarta, Indonesia. Research design, data, and methodology: This study uses official poverty statistics (National Socio-economic Survey (SUSENAS) and Poverty Database 2015) to compare satellite imagery's ability to identify poor urban areas in D.I Yogyakarta. National Socioeconomic Survey (SUSENAS), as poverty statistics at the macro level, uses expenditure to determine the poor in a region. Poverty Database 2015 (BDT 2015), as poverty statistics at the micro-level, uses asset ownership to determine the poor population in an area. Pearson correlation is used to identify the correlation among variables and construct a Support Vector Regression (SVR) model to estimate the poverty level at a granular level of 1 km x 1 km. Results: It is found that macro poverty level and moderate annual nighttime light intensity have a Pearson correlation of 74 percent. It is more significant than micro poverty, with the Pearson correlation being 49 percent in 2015. The SVR prediction model can achieve the root mean squared error (RMSE) of up to 8.48 percent on SUSENAS 2020 poverty data.Conclusion: Nighttime light satellite imagery data has potential benefits as alternative data to support regional poverty mapping, especially in urban areas. Using satellite imagery data is better at predicting regional poverty based on expenditure than asset ownership at the micro-level. Light intensity at night can better describe the use of electricity consumption for economic activities at night, which is captured in spending on electricity financing compared to asset ownership.

1910년 토지조사법 제정이후 110여년 만에 「지적재조사에 관한 특별법」이 제정되어 2030년까지 지적재조사사업이 추진될 예정이다. 본 사업에서 경계설정은 중요한 비중을 차지하고 있으며, 지적재조사측량규정에서는 지상경계 설정 기준에 대한 구체적인 예시를 두고 있다. 이러한 경계설정에는 지상경계뿐만 아니라 지적도상 경계, 지방관습에 의한 경계에 따라서 설정할 수 있으며, 토지소유자간에 합의한 경계로도 설정할 수 있다. 다만 토지소유자간 합의한 경계에 대해서는 지적소관청이 수용여부를 판단하여야 한다. 그러나 합의경계의 수용 여부를 판단하는 기준이 없으며, 합의경계를 악용할 수 있는 문제점 등이 나타나고 있다. 아울러 국가가 관리하는 공적 존재인 토지경계를 사인간 합의할 수 있는 대상인가라는 문제제기도 있다. 따라서 합의경계와 관련된 사항을 심층적으로 검토하여 개선안을 제시하고자 한다. 합의경계관련 사항의 개선을 통해 지적소관청의 판단기준을 정립하고, 토지의 효율적 이용이 증가되어 사업이 원활히 추진될 것으로 생각한다.

We examine gas kinematics and star formation activities of NGC 6822, a gas-rich dwarf irregular galaxy in the Local Group at a distance of ~490 kpc. We perform profile decomposition of all the line-of-sight (LOS) HI velocity profiles of the high-resolution (42.4" × 12" spatial; 1.6 km/s spectral) HI data cube of the galaxy, taken with the Australian Telescope Compact Array (ATCA). To this end, we use a novel tool based on Bayesian Markov Chain Monte Carlo (MCMC) techniques, the so-called BAYGAUD, which allows us to decompose a velocity profile into an optimal number of Gaussian components in a quantitative manner. We group all the decomposed components into bulk-narrow, bulk-broad, and non-bulk gas components classified with respect to their velocity dispersions and the amounts of velocity offset from the global kinematics, respectively. Using the surface densities and velocity dispersions of the kinematically decomposed HI gas maps together with the rotation curve of NGC 6822, we derive Toomre-Q parameters for individual regions of the galaxy which quantify the level of local gravitational instability of the gaseous disk. We also measure the local star formation rate (SFR) of the corresponding regions in the galaxy by combining GALEX Far-ultraviolet (FUV) and WISE 22㎛ images. We then relate the gas and SFR surface densities in order to investigate the local Kennicutt-Schmidt (K-S) law of gravitationally unstable regions which are selected from the Toomre Q analysis. Of the three groups, the bulk-narrow, bulk-broad and non-bulk gas components, we find that the lower Toomre-Q values the bulk-narrow gas components have, the more consistent with the linear extension of the K-S law derived from molecular hydrogen (H2) observations.

건축설계 초기 단계에서 대상 대지에 대한 지리 공간 정보의 사용은 필수적이다. 하지만 현재까지 이러한 정보의 취득은 상당한 시간 및 노력이 요구되는 일이다. 본 연구는 이러한 GIS 정보의 효과적 취득을 위해 현재 국토교통부 주관으로 서비스 되고 있는 국가공간정보유통시스템인 Vworld의 정보를 건축설계에 이용하는 방법을 제시한다. 제시하는 방법은 Vworld 에서 제공하는 Open API를 이용하여 건축설계 초기단계에 필요한 지형 형상, 지적도 및 토지의 용도, 개발제한 사항 등을 BIM 설계용 소프트웨어에서 검색 및 즉시 활용 할 수 있는 BIM/GIS통합 방법이다. 이를 통해 BIM 분야에서는 GIS분야에서 구축한 도시설계관련 정보를 활용 할 수 있고, GIS는 건축분야에서 구축한 건물관련 정보를 이용함으로서 지리 및 공간정보를 풍성하게 구축 및 지속적인 유지관리가 가능하게 할 수 있다. 또한 본 연구를 통해 구축된 시스템은 BIM소프트웨어를 이용하여 설계하는 건축설계자들이 프로젝트관련 지리공간정보를 취득하는데 많은 시간과 노력을 절약할 수 있다는 사실을 확인할 수 있다.

In recent years, soil erosion has come to be regarded as an essential environmental problem in human life. Soil erosion causes various on- and off-site problems such as ecosystem destruction, decreased agricultural productivity, increased riverbed deposition, and deterioration of water quality in streams. To solve these problems caused by soil erosion, it is necessary to quantify where, when, how much soil erosion occurs. Empirical erosion models such as the Universal Soil Loss Equation (USLE) family models have been widely used to make spatially distributed soil erosion vulnerability maps. Even if the models detect vulnerable sites relatively well by utilizing big data related to climate, geography, geology, land use, etc. within study domains, they do not adequately describe the physical process of soil erosion on the ground surface caused by rainfall or overland flow. In other words, such models remain powerful tools to distinguish erosion-prone areas at the macro scale but physics-based models are necessary to better analyze soil erosion and deposition and eroded particle transport. In this study, the physics-based Surface Soil Erosion Model (SSEM) was upgraded based on field survey information to produce sediment yield at the watershed scale. The modified model (hereafter MoSE) adopted new algorithms on rainfall kinematic energy and surface flow transport capacity to simulate soil erosion more reliably. For model validation, we applied the model to the Doam dam watershed in Gangwon-do and compared the simulation results with the USLE outputs. The results showed that the revised physics-based soil erosion model provided more improved and reliable simulation results than the USLE in terms of the spatial distribution of soil erosion and deposition.

This study was conducted to investigate and analyze food related and space related elements of popular Vietnamese restaurants in Hong Kong to identify restaurant images related to food, to examine how Vietnamese traditions are applied to such restaurants, and ultimately, to get their implications for us. Luxury Vietnamese restaurants in Hong Kong tended to be located in major office buildings and famous shopping malls in the downtown area; therefore, they were highly accessible to foreigners. In addition, most Vietnamese restaurants were quite formal in size or atmosphere. The food-related elements of the luxury restaurants reproduced traditional menus, but the table setting and service generally adopted a formal Western style setting. The presentation of foods was also creative and contemporary, to suit international customers' tastes. Regarding the spatial elements, restaurants serving traditional menus had interiors influenced by the French colonial period, while those serving contemporarily adapted menus had interiors with simple contemporary images emphasized by Vietnamese traditional decorations. These characteristics allowed foreigners from diverse countries to access the restaurants without a sense of rejection. Casual restaurants were primarily exposed to many people on busy roadsides, but they tended to be inferior in terms of size and quality. Apart from size and price level, food-related elements failed to reflect Vietnamese unique traditional characteristics. The outward appearance consisted of basic construction materials (glass, chassis, and bamboo) instead of those representing Vietnamese architecture. Additionally, the interior of the casual restaurants contained traditional elements or objects more frequently than luxury restaurants, but they looked rather disorderly and lacked harmony. Overall, the image of casual restaurants was degraded by the use of cheap and low quality finishing materials and furniture. The results of this study may be useful for organizations promoting the Branding of Korea or businesspeople and designers promoting the globalization of Korean foods.

We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Volume at a distance of ~490 kpc. We perform profile decomposition of the line-of-sight velocity profiles of the high-resolution (~42.4" × 12") spatial; ~1.6 km/s spectral) H I data cube taken with the Australia Telescope Compact Array (ATCA). For this, we use a new tool, the so-called BAYGAUD (BAYesian GAUssian Decompositor) which is based on Bayesian Markov Chain Monte Carlo (MCMC) techniques, allowing us to decompose a line-of-sight velocity profile into an optimal number of Gaussian components in a quantitative manner. We classify the decomposed H I gas components of NGC 6822 into kinematically cold, warm or hot ones with respect to their velocity dispersion: 1) cold: < 4 km/s, 2) warm: 4 ~ 8 km/s, 3) hot: > 8 km/s. We then derive the Toomre-Q parameters of NGC 6822 using the kinematically decomposed H I gas maps. We also correlate their gas surface densities with the surface star formation rates derived using both GALEX far-ultraviolet and WISE 22 micron data to examine the impact of gas turbulence caused by stellar feedback on the Kennicutt-Schmidt (K-S) law. The kinematically cold component is likely to better follow the linear extension of the Kennicutt-Schmidt (K-S) law for molecular hydrogen (H2) at the low gas surface density regime where H I is not saturated.

The purpose is to derive its aesthetic characteristics by objectifying the visual image of the YouTube campaign into adjectives. As a result, we intend to identify advertising strategies that use them as basic data for setting fashion design concepts. A group of experts in fashion majors watched each of them, wrote adjectives, and collected 75 adjectives. By analyzing the frequency of adjectives, aesthetic characteristics were derived with adjectives recording the upper number of times, and the results were obtained that they had the characteristics of deconstruction. The conclusions of this study are as follows. First, Tamburin's Jenny appeared to be strange, scary, rambling and charming. Among the internal meanings of deconstruction due to spatial, social, and psychological distance from consumers, it can be said that T.P.O's mutual textuality and play of interaction. Second, Gucci Cruise be chosen rural, strange, wild, unharmonious, and difficult, which is a mixture of intertextuality and play of T.P.O. Third, The Excise Gucci Campaign parodies that juxtaposes six films directed by Stanley Kubrick, making them strange, retro, difficult, interesting, and wrong. Deconstructionist de-genre and de-boundary Fourth, Kenzo World is weird, dynamic, wrong, difficult, difficult, and confused, which correspond to T.P.O's interactive textuality, play of the second half, and destruction and decomposition among the external expressions of deconstruction. Fifth, Burberry Hero emphasized the aesthetic value of traditional men, so it was ostensibly wild, free, powerful, sensual, and fantastic. Compared to the lifestyle of men who usually work at work, this corresponds to play of second best.
