Results of a trans-boundary ecological survey of the cross-border Rolava and Weisseritz river catchments in the Erzgebirge/Krušné hory are presented. An optimized method to assess the ecohydrological status of streams in keeping with the European Water Framework Directive has been developed. Guiding parameters for the hydromorphological survey were selected, used for (1) the German “Gewaesserstrukturguetekartierung” by the Field Survey method of the Laenderarbeitsgemeinschaft Wasser, (2) the Czech EcoRivHab method and (3) the Czech HEM method that additionally comply with the requirements of the European Standard EN 14614. Hydrochemical monitoring supported the interpretation of the hydrobiological data. The assessment followed the stream type specific background and orientation values. Hydrobiological monitoring focussed on benthic macroinvertebrates, stream type, and stressor specific assessment. Five ecohydrological quality classes were established from 1 (high) to 5 (bad), characterizing the state of the water course in the WFD context.

Hydromorphological Quality

The main goal of this paper is to verify the hypothesis that application of appropriate restoration measures can lead to an improvement in river habitat quality and to achieve good hydromorphological conditions within the ecological status under the Water Framework Directive 2000/60/ES. The study includes an analysis of river network modifications founded on comparing historical and present-day maps, a determination of regional hydromorphological reference conditions based on a field survey and measurements, an assessment of hydromorphological quality of the studied water body and a proposal of appropriate restoration measures. The effects on improvement in hydromorphological status were predicted on the basis of a simulation of hydromorphological conditions after the application of proposed restoration measures. Overall, at least a good hydromorphological status would be achieved. The study proved that it is essential to carry out a hydromorphological survey including a determination of reference conditions as it provides some outputs necessary for a proposal and application of efficient restoration.

Chamber Study

The study of thermal comfort in buildings is required to maintain a stable and comfortable condition of the indoor environment. The climate chamber study used to determine thermal comfort is mathematically reproducible and robust, but exaggerative and hence is energy inefficient, whereas the adaptive model-based field survey method is exhaustive and bioclimatic specific. Although, several field survey-based thermal comfort studies have been reported from India, these studies were conducted mostly either in hot and humid or composite climatic condition, and very few research has been reported from cold climatic region, which lies mostly along the high altitudinal Himalayan region. In this paper, the results of field survey-based thermal comfort studies in residential houses of highly altitudinal Darjeeling Himalayan region in eastern India are presented. The study found that female subjects showed a lesser clothing cover but portrayed a higher discomfort with lower thermal sensation and higher comfort temperature. The comfort temperature as determined in this study did not comply with the ASHRAE standard 55 graphical method, and hence new comfort zone for regions with similar cold climate is proposed.

AbstractSpatially-explicit approaches are widely recommended for ecosystem management. The quality of the data, such as presence/absence or habitat maps, affects the management actions recommended, and is, therefore, key to management success. However, available data are often biased and incomplete. Previous studies have advanced ways to resolve data bias and missing data, but questions remain about how we design ecological surveys to develop a dataset through field surveys. Ecological surveys may have multiple spatial scales, including the spatial extent of the target ecosystem (observation window), the resolution for mapping individual distributions (mapping unit), and the survey area within each mapping unit (sampling unit). We developed an ecological survey method for mapping individual distributions by applying spatially-explicit stochastic models. We used spatial point processes to describe individual spatial placements using either random or clustering processes. We then designed ecological surveys with different spatial scales and individual detectability. We found that the choice of mapping unit affected the presence mapped fraction, and the fraction of the total individuals covered by the presence mapped patches. Tradeoffs were found between these quantities and the map resolution, associated with equivalent asymptotic behaviors for both metrics at sufficiently small and large mapping unit scales. Our approach enabled consideration of the effect of multiple spatial scales in surveys, and estimation of the survey outcomes such as the presence mapped fraction and the number of individuals situated in the presence detected units. The developed theory may facilitate management decision-making and inform the design of monitoring and data gathering.

Abstract : BPK and Badran intersection located at the center of Yogyakarta City that can not be separated from traffic issues. Both intersections have a closed distance within 380 meters with the high  volume of vehicles that passing through them. Traffic microsimulation using VISSIM software was used to perform queue length, travel time, delay on existing condition and signal coordination design. The research was conducted by field survey method to find the traffic volume, geometry and vehicle speed. Level of service of the intersection was refers to the Minister of Transportation Regulation number 96/2015. As the result, the performance of two intersections at the existing have not been coordinated and has low value of service level.    Therefore, two solutions design were used to coordinate signals between intersections.         Alternative I was coordinated signals of intersections and the second alternative was used the signals coordination with one-way system at the road beetwen intersection. From both alternatives, the second alternative was better than the other.Keywords : Signal Coordination, Microsimulation, One Way System, VISSIM.Abstrak: Simpang BPK dan Simpang Badran yang terletak di pusat Kota Yogyakarta tidak lepas dari permasalahan lalu lintas. Selain karena tata guna lahan di sekitarnya yang sibuk juga dikarenakan kedua simpang tersebut memiliki jarak 380 meter. Dalam penelitian ini, mikrosimulasi lalu lintas dengan software VISSIM digunakan untuk melakukan analisis panjang antrian, perjalanan waktu tempuh, dan tundaan pada kondisi eksisting dan perancangan koordinasi sinyal. Survei pengambilan data primer meliputi volume lalu lintas, geometri simpang dan kecepatan kendaraan. Setelah dimodelkan dengan software VISSIM, tingkat kinerja simpang dianalis dengan mengacu pada Peraturan Menteri Perhubungan nomor PM 96 Tahun 2015. Dari hasil analisis, diketahui bahwa Simpang BPK dan Simpang Badran belum terkoordinasikan. Setelah itu, dilakukan dua solusi perancangan untuk melakukan koordinasi sinyal antar simpang pada kedua simpang tersebut. Alternatif I mengkoordinasikan sinyal kedua simpang tersebut dan alternatif kedua dengan menggunakan sistem satu arah di jalan penghubung dengan tetap terkoordinasi sinyal waktunya. Dari kedua alternatif perancangan tersebut, didapatkan alternatif kedua yang terbaik.Kata kunci : Koordinasi Sinyal, Mikrosimulasi, Sistem Satu Arah, VISSIM.

Border residents have been noted for their involvement in goods smuggling and other illegal cross border exchanges as coping mechanisms for poverty and unemployment. This study assesses the veracity of this claim through a field survey of the eastern border town of Aflao. The result of the study shows that challenges of poverty and unemployment have forced border residents to exploit their location in the border space as coping strategy by engaging in officially proscribed activities. These activities involve crimes such as goods smuggling, smuggling facilitation, armed robbery and petty stealing, drug trafficking, human trafficking and arms trafficking. While border residents are likely to see some of these activities (armed robbery and petty stealing, drug trafficking, human trafficking and arms trafficking) as crimes, they would normally accept that goods smuggling and aiding smuggling are not crimes because they serve as livelihood options, which contribute to reducing unemployment and poverty in border areas. To be effective, border management has to be comprehensive and incorporate the livelihood needs of Borderlanders.

The present research has sought to identify the features and capabilities of the smart city and their status in Tehran, identifying the strengths and weaknesses of this city in comparison with the smart city. For this purpose, first, the models and foundations of the smart city and its features presented by other researchers have been studied. The result of this study was to categorize Smart City features into six categories. The field survey of the topic by descriptive-survey method showed that these characteristics are confirmed by the statistical community as the characteristics of the smart city. With the ranking of 50 effective features, in addition to identifying important features in each category, 10 characteristics were identified as the most effective characteristics. The results show that among 50 characteristics, Tehran has only a relatively good status in eight characteristics. In other words, 84% of the characteristics in Tehran are not well-suited. The existence of such a situation cannot be ruled out by the integrated management factors on the affairs of the city of Tehran; there is no long-term plan for Tehran, and the relationship between people and government and the authorities is not related to partnership and cooperation.
