The major reason that the fully automated generalization of residential areas has not been achieved to date is that it is difficult to acquire the knowledge that is required for automated generalization and for the calculation of spatial similarity degrees between map objects at different scales. Furthermore, little attention has been given to generalization methods with a scale reduction that is larger than two-fold. To fill this gap, this article develops a hybrid approach that combines two existing methods to generalize residential areas that range from 1:10,000 to 1:50,000. The two existing methods are Boffet’s method for free space acquisition and kernel density analysis for city hotspot detection. Using both methods, the proposed approach follows a knowledge-based framework by implementing map analysis and spatial similarity measurements in a multiscale map space. First, the knowledge required for residential area generalization is obtained by analyzing multiscale residential areas and their corresponding contributions. Second, residential area generalization is divided into two subprocesses: free space acquisition and urban area outer boundary determination. Then, important parameters for the two subprocesses are obtained through map analysis and similarity measurements, reflecting the knowledge that is hidden in the cartographer’s mind. Using this acquired knowledge, complete generalization steps are formed. The proposed approach is tested using multiscale datasets from Lanzhou City. The experimental results demonstrate that our method is better than the traditional methods in terms of location precision and actuality. The approach is robust, comparatively insensitive to the noise of the small buildings beyond urban areas, and easy to implement in GIS software.

Urban areas are generally in the form of housing with narrow land. The purpose of this activities was to use narrow land for farming with verticulture techniques. The activity was held in Puri Zahara 1 Residence, Medan Tuntungan District. which is a residential area with narrow land. The method used was to provide training to housewife to be able to utilize the land with verticulture techniques. Housewives was briefed in order to be able to use the land using existing materials, especially verticulture techniques. The material used in verticulture techniques was paralon. The result of this dedication is that the community can utilize small land, especially in residential areas with verticulture techniques to plant flowers or vegetable crops, so that the house becomes greener and livelier. With this verticulture technique, more vegetable or fruit crops can be planted.  some plants planted include lettuce, water spinach, flowers

In certain cases, the conversion of paddy fields is unavoidable. Nevertheless, the change in land use must consider various aspects of the feasibility of development, both legal aspects, physical aspects of the area, the environment and others.The objectives are to, analyze the implementation of the policy on the transfer of agricultural land into residential areas, and analyze the factors that support and hinder the implementation of the policy. The type of research used is descriptive qualitative, using primary and secondary data. Data collection methods are interviews, in-depth (Indep interview) and direct discussion or Focus Group Discussion (FGD), observation and literature review. The results of the study indicate that the activity of land conversion into a residential area in West Lombok Regency has been guided by the Regional Regulation and Regional Spatial Planning (RSP) No. 11 / 2011. The use of agricultural land for residential areas has been regulated in the determination of the spatial pattern of residential areas in urban areas. and rural areas, the inhibiting factor in implementing the land use change policy is the absence of a detailed regional spatial planning plan and the limited number of field officers. The supporting factors are the Regional Spatial Planning Coordination Team, which is coordinated by the Regional Secretary. The recommendation given is to immediately issue a Detailed Spatial Plan so that there is an even distribution of housing areas. It is necessary to make a regional regulation that specifically examines and regulates the conversion of land functions.

Ozone (O3) have many adverse impacts toward the living human, environment and O3 formed through the photochemical reaction with the aid of sunlight. Therefore, this study focused on the determination of O3, nitric oxide (NO), nitrogen dioxide (NO2) concentrations and meteorological parameters (temperature, humidity, wind speed and wind direction) three residential area namely Taman Tun Dr Ismail Jaya, Selangor as the urban area, Taman Delima, Sungai Petani, Kedah as the sub urban area and Taman Kifayah, Jeli, Kelantan as the rural area. The monitoring were continuously done for three days in 24 hours from 12 a.m. until 12 a.m. per day at each site. Aeroqual S500 series and weather station model RK900-01 were used to measure O3, NO, NO2 concentrations and meteorological parameters. The concentration of O3, NO, NO2 and the meteorological parameters were determined and O3 concentration was compared by one-way analysis of variance (ANOVA). Among the studied areas, the highest mean O3 concentration was recorded in Taman Delima, Sungai Petani with 35.2 ppb followed by Tun Dr Ismail Jaya with 33.3 ppb. Result suggested that sub urban areas showed higher mean O3 concentration compared to urban area which might linked to the availability of the O3 precursors in the area. As expected, the lowest mean O3 concentration recorded at Taman Kifayah, Jeli with 12.1 ppb as the area have limited O3 precursor’s sources. However, the ozone concentration at three residential areas were still under permissible level according to Recommended Malaysia Ambient Air Quality Guidelines (RMAAQ).

Вертикальное озеленение с участием различных видов лиан в современных условиях имеет важное эстетическое и санитарно-гигиеническое значение. Особо актуально решение вопросов обогащения флоры городских территорий лианами в степных районах в связи с бедным видовым составом и резким ухудшением экологической ситуации. Объектами исследований являлись 7 видов лиан, различных жизненных форм (однолетние, многолетние), произрастающие в населенных пунктах Саратовской области (Аткарск, Саратов). Цель исследований – изучение эколого-биологических особенностей и мелиоративных свойств лиан и выявление перспектив их использования в вертикальном озеленении селитебных территорий Саратовской области. В ходе исследования видового состава, были выявлены наиболее популярные виды однолетних лиан: ипомея красно-голубая (Ipomea tricolor (L.) Roth) и ипомея пурпурная (Ipomea purpurea (L.) Roth), горошек душистый (Lathyrus edoratus L.), настурция (Tropacolum peregrinum L.) и фасоль огненно-красная (Phaseolus coccineus). Большинство (70%) из них произрастают в местах ограниченного пользования. Изученные виды лиан в исследуемых регионах достигают средних природных показателей (при наличии надлежащего ухода), обладают хорошими показателями жизненного состояния, обильно цветут и плодоносят. При воздействии токсикантами различной концентрации на листовые пластинки лиан установлено их степень устойчивости. Выявлено, что однолетние лианы лучше использовать в декоративных целях, а не в санитарно-гигиенических. Сравнительная оценка однолетних видов с многолетними лианами (девичий виноград пятилисточковый и клематис тангутский) показывает устойчивость многолетних видов (в среднем на 3 балла - 40%). Разработаны варианты декоративных композиций с участием травянистых лиан. По степени декоративности выделены однолетние лианы – Ipomea tricolor, I. purpurea (37 – 41 балл), средней степенью отличаются – Lathyrus edoratus (33 балла), Tropacolum peregrinum (30 баллов) и Phaseolus coccineus (20 – 27 баллов). Преимущество многолетних лиан заключается в их устойчивости к резким изменениям климатических условий (на 40 %) по сравнению с однолетними формами. Поэтому они более предпочтительны для озеленения городской среды. Для усиления декоративного эффекта в сезонном аспекте рекомендуются сочетать расширение видового и формового разнообразия растений (многолетние и однолетние лианы, древесно-кустарниковая, цветочная растительность). Установлено, что природно-климатические условия зоны степи и лесостепи в пределах Саратовской области являются достаточно благоприятными для нормального роста и развития древесно-кустарниковой растительности, в том числе травянистых лиан. Таким образом, обоснованное применение древесных лиан в комплексе с традиционными видами насаждений позволит создать комфортные условия проживания населения, регулировать оптимальный температурный баланс и создавать благоприятные микроклиматические условия. Vertical gardening with different types of vines in modern conditions is important aesthetic and sanitary-hygienic value. It is especially important to address the issues of enrichment of the flora of urban areas with vines in the steppe regions due to poor species composition and a sharp deterioration of the ecological situation. The objects of research were 7 species of lianas, various life forms (annual, perennial), growing in the settlements of the Saratov region (Atkarsk, Saratov). The aim of the research is to study the ecological and biological features and reclamation properties of vines and identify the prospects for their use in vertical gardening residential areas of the Saratov region. In the study, species composition was the most popular species of annual vines: morning glory red-blue (Ipomea tricolor (L.) Roth) and purple morning glory (Ipomea purpurea (L.) Roth), the fragrant pea (Lathyrus edoratus L.), nasturtium (Tropacolum peregrinum L.) and runner beans (Phaseolus coccineus). Most (70%) of them grow in restricted areas. Studied species of vines in the study regions reach average natural performance (with proper care), have good indicators of vital condition, bloom abundantly and bear fruit. When exposed to toxicants of different concentrations on the leaf blades of vines established their degree of stability. It was revealed that the annual vines are better used for decorative purposes, and not in the sanitary-hygienic. A comparative assessment of annual species with perennial vines (maiden grapes and clematis Tangut) shows the stability of perennial species (an average of 3 points-40%). The options and decorative compositions with the participation of herbaceous vines. According to the degree of decoration of the allocated annual vine – Ipomea tricolor, I. purpurea (37 – 41 points), the average degree of differ – Lathyrus edoratus (33 points), Tropacolum peregrinum (30 points) and Phaseolus coccineus (20 to 27 points). The advantage of perennial vines is their resistance to sudden changes in climatic conditions (40 %) compared to annual forms. Therefore, they are more preferable for greening the urban environment. To enhance the decorative effect in the seasonal aspect, it is recommended to combine the expansion of species and form diversity of plants (perennial and annual lianas, tree and shrub, floral vegetation). It is established that the climatic conditions of the steppe and forest-steppe zone within the Saratov region are quite favorable for the normal growth and development of tree and shrub vegetation, including herbaceous lianas. Thus, the reasonable use of wood vines in combination with traditional types of plantings will create comfortable living conditions for the population, regulate the optimal temperature balance and create favorable microclimatic conditions.

AbstractThe site of Sirkeli Höyük in the province of Adana in modern Turkey is one of the largest settlement mounds in Plain Cilicia. In 2012, a geophysical survey revealed that the ancient settlement was not confined to the höyük, but also encompassed an extensive lower town to the southeast of the main mound. To gain information on the dating and development of this part of the settlement, an excavation area (“Sector F”) was opened at a spot where the magnetometry survey suggested the presence of a city gate. Since then, archaeological work in this area has continuously produced new discoveries that help us understand how this residential area and its inhabitants developed throughout the periods of its occupation. Especially the Iron Age (Neo Cilician period) levels, which cover approximately the 11th–7th centuries B.C., provide important information on how this urban center of the Neo Hittite kingdom Hiyawa/Que changed over time and to which extent historical events impacted the people living in one of its residential areas. This contribution discusses the stratigraphic sequence, the pottery, and the archaeobotanical remains discovered in Sector F during the 2013–2019 campaigns, and concludes with a synthesis of the development in this area from a historical perspective.

Wines with geographical indication can be classified and represented by such features as designations of origin, producers, vintage years, alcoholic strength, and grape varieties; these features allow us to define wines in terms of a set of necessary and/or sufficient conditions. However, wines can also be identified by other characteristics, involving their look, smell, and taste; in this case, it is hard to define wines in terms of necessary and/or sufficient conditions, as wine concepts exhibit typicality effects. This is a setback for the design of computer science ontologies aiming to represent wine concepts, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits. To solve this problem, we propose to adopt a hybrid approach in which ontology-oriented formalisms are combined with a geometric representation of knowledge based on conceptual spaces. As in conceptual spaces, concepts are identified in terms of a number of quality dimensions. In order to determine those relevant for wine representation, we use the terminology developed by the Italian Association of Sommeliers to describe wines. This will allow us to understand typicality effects about wines, determine prototypes and better exemplars, and measure the degree of similarity between different wines.

This study evaluates people’s preferences regarding the proximity of their residence to agricultural urban green infrastructure (UGI), such as agricultural land and satoyama, and discusses the availability of these types of land as UGI. UGI is vital for reducing the negative environmental impacts of urban areas, as these impacts are too large to ignore. In this study, we conducted an online survey and a choice experiment to investigate people’s perceptions regarding the proximity of their residence to agricultural UGI (AUGI). The respondents of the choice experiment were 802 inhabitants of Ishikawa Prefecture, Japan, which has rich agricultural resources. To examine explicitly the spatial autocorrelation of people’s preferences, in this study, we used the spatial econometrics method. The main empirical findings are that people prefer agricultural land far away from their residence—more than 1000 m, not within 1000 m—which reflects the not-in-my-backyard phenomenon. Meanwhile, people’s preferences regarding proximity to satoyama are complicated and their preferences are positively spatially autocorrelated. The results indicate that policymakers and urban planners should manage and provide AUGI far away from residential areas; otherwise, they must address people’s avoidance of neighboring AUGI.
