Unlike natural ecosystems, the urban ecosystem proVides an interdependent enVironment in which wild organisms and urban people co-exist. Hornets (genus Vespa) appearing in urban green and parks haVe a positiVe effect on urban ecosystems, but they also cause ecosystem disserVices that cause physical and psychological discomforts to the urban people. Children's parks, for example, are Very popular among children and residents for easy accessibility, and hornets also use them as bases and habitats. HoweVer, there is still a lack of spatial analysis of habitats and appearance characteristics of hornets in children's parks. This study installed hornet traps in 27 children's parks in Cheonan from April to NoVember 2018 in consideration of the life cycle of hornets. We captured a total of fiVe Vespa species (Vespa crabro, V. analis, V. mandarinia, V. ducalis, and V. Velutina) for 32 weeks and analyzed the emergence of hornets in relation to the composition of seasonal characteristics, species characteristics, and enVironmental spatial information. We captured a total of 818 hornets during the study period. They included 290 V. analis (35.4%), 260 V. crabro (31.8%), 100 V. ducalis (12.1%), 87 V. mandaninia (10.6%), and 81 V. Velutina(9.9%). Most of the hornets showed a common feature that queen hornets were largely captured in May through June after they awake from hibernation, and the number of caught hornets decreased sharply beginning in mid-June, which was the cooperatiVe period. HoweVer, V. Velutina showed a seasonal specificity that more than 80% were captured beginning in the third week of October when other hornet species had already entered a decline phase. The analysis of the number of hornets caught in each spot in children's parks showed significant difference among the spots as 363 hornets (44.3%) were captured in top children's parks, and 35 hornets (4%) were captured in bottom children's parks. In particular, the mean NDVI (Normalized difference Vegetation index) of the top six children's parks was 0.79, and that of the bottom six children's parks was 0.38 (t=2.67*, *=p<0.05), indicating a significant difference. The frequency of capturing hornets was high when the ground around the children's parks was grass or bare land. This study is meaningful as a reference study that confirms the ecological characteristics of hornets appearing in green and parks in the city. We expect it to be a foundation for effectiVe urban green area management in the future.

As the urbanization trend in modern society continues, the concentration of the population induces the urban problems in the residential area. One of the well-known issues among various urban problems is the garbage problem, which causes deterioration of the residential environment of citizens and directly affects the satisfaction of municipal administration. Such garbage problem cannot be accurately predicted by analyzing the amount of waste emitted from residential areas, but it is necessary to analyze the lifestyle and characteristics of residents living in residential areas. In this study, we propose an agent-based residential modeling and simulation environment using discrete event system formalism to analyze the garbage problem and satisfaction level according to the distribution of residents in the residential area. To model the behavior of the residents, we utilized the Atomic Model to capture the temporal behavior. Also, we used the Coupled Model to model the multi-family and the building to enhance the reusability of the simulation model. Also, this study carried out simulation modeling and simulation for a multi-family residential area. The simulation results of the multi-family housing area show that considering the characteristics of the residents gives better results compared to the simulation results without considering the characteristics.

Disasters that destroy homes and infrastructure and cause significant financial damage are becoming more common as population centers grow. In addition, several natural disasters have resulted in a major loss of life and created countless refugees due to damage to housing. After major catastrophic disasters, it is very important that the government agencies respond to post-disaster housing issues and provide resources such as temporary housing before the full rehabilitation and reconstruction of destroyed and damaged housing. To provide affordable temporary housing for residents who may lose their homes as the result of a catastrophic disaster including storms, government agencies must develop a post-disaster housing prototype. In general, government agencies should explore several different forms of factory-built single-story, single family housing, such as modular homes, panelized homes, and precut homes. In urban cities including New York and Seoul, it is very important to provide housing which supports the demand for higher-density living spaces than single-family homes or trailers typically available due to the high population density and the desire to resettle as many residents as possible in their former neighborhoods. This study identified the urban post-disaster housing prototypes that may provide higher density housing with high quality living spaces, high air quality, and energy efficiency as well as rapid deployment. A case study of "Urban Post-Disaster Housing Prototype Program in New York" was conducted through a detailed interview process with a designer, engineer, contractor, the Office of Emergency Management (OEM) in New York, the U.S. Army Corps of Engineers (USACE), and temporary occupants. An appropriate disaster housing program that can provide living spaces for victims of disasters that keeps residents in their community and allows them to live and work in their neighborhoods was developed.

도시 계획의 중요성이 부각되면서 다양한 도시 통합 모델의 개발이 이루어져왔으나 기존 모델들은 거시적 측면의 토지이용의 변화만 다루는 한계점이 있다. 본 논문은 토지이용 변화뿐만 아니라 다양한 사회 경제 지표를 반영하여 미시적인 분석이 가능한 UrbanSim 모델을 사용하여 사례연구를 통한 국내 도입 가능성과 시사점을 도출하고자 하였다. 이를 위해 수치지적도, 건축물 대장, 개별 공시지가 등 다양한 시공간 데이터를 이용하여 $150{\times}150m$ 그리드 셀 기반의 입력 데이터베이스를 구축하고 UrbanSim의 Land Price Model에 적용하였다. 향후 보다 현실적인 모델 수행을 위한 다중 스케일 및 Synthetic 데이터 구축 방안과 접근성 측면의 교통 통합 모델로 확장이 요구된다.

The aim of the present study is to explore the following two key questions on woman's attitude toward the clothing : (1) Their willingness to make their own dress at home : (2) purchasing tendencies of ready-made wear. The data were drawn through questionaires collected form 495 women in random sampling-335 housewives and 160 high school woman teachers living in Seoul. The findings are ; 1. As a whole there is no significant difference between the teachers and the housewives in their attitudes on clothing and home dressmaking. 2. Teachers and housewives alike have shown the tendency to avoid to take the trouble to make their own dresses themselves due, in large measure, to the technical difficulties of dressmarking. 3. On account of general shortcomings of ready-made clothing such as poor quality cloth, casual workmanship, inadequate assortment, unfitness of size to figure and outdated fashion, they purchase ready-made only for casual uses and really resort to tailor made for formal dresses. Since this paper is preliminary report, the accounts are to intend to be suggestive rather than conclusive, and more detailed and profound must, of course, await further empirical research.

태양광발전량의 예측에 대해 많은 선행연구가 진행되었으나 연간 또는 월별 총발전량을 비교하기 위한 것이 주류였기 때문에 연간 또는 월별의 평균일사량을 바탕으로 발전량을 예측 비교하고 있다. 그러나 도시차원에서 전력생산 및 공급의 최적화를 위해서는 시간 및 기상에 따란 변화하는 일사량과 그에 따른 발전량을 예측하여 효율적인 전력생산 공급계획을 수립할 필요가 있지만 기상예보에는 일사량 정보가 포함되어 있지 않기 때문에 기상예보에 제공되는 운량을 이용하여 일사량을 예측할 수 있는 기법개발이 절실하다. 본 연구에서는 해양도시인 부산을 대상으로 과거의 기상데이터 중 운량과 일사량을 이용하여 일사량 예측기법을 제안하고자 한다.

The purpose of this study was to investigate the effect of generation on consciousness toward wedding ritual and to compare the difference in their consciousness between the young and the old. Data were obtained from 489 individuals living in Seoul. OLS regression analysis was used to identify the effect of generation on consciousness toward wedding ritual. The effect of generation was significant in the consciousness of wedding procedures, while it was not significant in the consciousness of wedding expenditures, holding other factors constant. [t was also found that procedure-important style was associated with more expenditures on wedding. The findings of this study suggested that the materialism had an important effect on the consciousness of wedding procedures for both generations. Understanding these factors is useful for family resource management professionals and educators who develop educational programs to build desirable wedding culture in Korea.
