Optimal layout of a forest road network The road network is the backbone of forest management. When creating or redesigning a forest road network, one important question is how to shape the layout, this means to fix the spatial arrangement and the dimensioning standard of the roads. We consider two kinds of layout problems. First, new forest road network in an area without any such development yet, and second, redesign of existing road network for actual requirements. For each problem situation, we will present a method that allows to detect automatically the optimal road and harvesting layout. The method aims to identify a road network that concurrently minimizes the harvesting cost, the road network cost (construction and maintenance) and the hauling cost over the entire life cycle. Ecological issues can be considered as well. The method will be presented and discussed with the help of two case studies. The main benefit of the application of optimization tools consists in an objective-based planning, which allows to check and compare different scenarios and objectives within a short time. The responses coming from the case study regions were highly positive: practitioners suggest to make those methods a standard practice and to further develop the prototype to a user-friendly expert software.

AbstractThe growing demand for quality in the Energy Distribution Service, both by consumers and by regulatory agencies, obliges most distribution utilities to apply technologies that can be easily implemented and produce results in a short term horizon. The telecontrol technology is an essential tool every time it is necessary to fast restore the energy supply. This technology, which is completely supervised and controlled by the system operation center, allows the fast detection of a fault at a distance and switch an equipment without the aid of the operating crew, thus reducing the time that the power supply is unavailable. The present paper describes a Telecontrol Project, incorporated in an electric energy distribution utility in Brazil and compares the results in quality improvement with others usual investment actions, such as operating and maintenance procedures, laterals protection and network reinforcement. This paper shows, analyzing the results, that to improve the reliability indexes in a short time, when the company’s economic recovery is more important, the application of remotely controlled switch is more effective.

AbstractThe Cariri region is the most isolated and poor part of the rural zone of the diocese of Campina Grande in the Paraiba state of Brazil. The Catholic Church has been present here for a relatively short time: 335 years. Moreover the region has an isolated context and this favors conservatism so that only fundamental changes have an impact. These facts make the Cariri an interesting region for a case study about how Catholicism develops. I distinguish five periods, which are described with religious key words and situated in the socio-cultural context. This classification is a schematization: different types of Catholicism often exist together. It is obvious that the dominant features of Catholicism change with time, but in the mainstream of the fifth period we see a small revolution. Now there are not only influences in the socio cultural context and factors in the Church itself that cause changes, but there are also influences of powerful newcomers, the evangelical churches. Their main impact is that many people have left the Catholic Church and are going to live their old faith in a new form. The Catholic Church is searching for adequate ways to respond to this phenomenon.

In pandemic era, almost everyone struggles for their life. College students are such example. They have difficulty in paying tuition fee to continue their study. Based on this problematic situation, Universitas Teknokrat Indonesia grants the students who have good academic performance with tuition fee aid program. Many variables used for determining the grant made it hard to make a decision in a short time or even takes very long time. To make it easier for management to decide who is the right student to get grant, it needs classification model. The purpose of this study is the classification of grant recipients by using decision tree C4.5 algorithm. That can determine whether a potential student can be accepted as an awardee or not. Then, the results of the classification are validated with ten-fold cross validation with an accuracy, precision and recall with the score of 87 % for all part. It means the model perform quite well to be implemented into system.

The Tlingit Aboriginal tourism enterprise named Icy Strait Point in Hoonah, Southeast Alaska is used as a case study to develop the new concept of Sustainable Social-Environmental Enterprise (SSEE). SSEE is defined as an innovative enterprise that has dynamic operational strategies while still maintaining its corporate core values and integrating social, environmental, cultural, economic and political (SECEP) sustainabilities in its operations. The SSEE framework assesses enterprises according to five domains of sustainability: social, environmental, cultural, economic, and political. Applying this framework, we find that while social, economic, and cultural sustainability goals have been achieved in a relatively short time by the Aboriginal tourism enterprise in Hoonah, the political and environmental spheres of sustainability are constrained by the dominant influence of the multinational cruise ship industry over tourism development. Thus, for an emerging tourism enterprise to be sustainable, we suggest each of these livelihood dimensions needs to achieve "a safe operating space" that is adaptable over time and to changing social and environmental circumstances.

In modern times, competitiveness in the market depends on having a good information system. The companies developing and supplying information systems are in competition too, and having an effective system of delivery is critical for obtaining lucrative offers. Therefore, the software development companies continuously try to improve their development process to supply the product in a short time and with high quality. The agile approach potentially shortens this time and is very often used. This approach has almost replaced the traditional process. More and more companies implement agile approach in these times to be competitive in the software development market and hasten product delivering.The traditional and agile approaches differ in certain perspectives. Hence, the question arises as to whether the agile approach is the best for the software development company in every case. This article contains a comparison of these two approaches, as well as a case study relating to the agile approach in a real software development company, which had previously used the traditional approach. The article also describes situation where replacing the traditional approach with agile would improve results.

This article analyzed the use of rapid ethnographic methodologies to assess community concerns for urban design practices. Rapid Ethnographic Assessment Process (REAP) is a compilation of methodologies that produce ethnographic knowledge in a short time frame and is constantly used for public health and sustainability. The article is about a participatory case-study conducted in the historic city center of Santiago de Los Caballeros, in the Dominican Republic. REAP was used to understand its application for urbanism. The case-study revealed a spectrum of cultures from different groups within the study area, and how the project would impact their ways of life. It also depicted a gap between the pre-existing proposals and the aims and challenges of the community groups. If appropriately applied, REAP can produce valuable results, and help inform urban design practices while assuring that they are respectful to the populations they will influence.

Pupils’ school dropout could be defined as an early and final abandonment of school before graduation, which prevents the pupil from registering in the following stage of education, losing in this way the possibility of benefiting from a proper and higher education. The statistics show that, unfortunately, in recent years school dropout rates have been increasing among secondary school pupils. The University of Oradea and The Bihor County School Inspectorate, Romania, have implemented a project called “School. My chance!” The aim of the project was to prevent and reduce the phenomenon of early school leaving by 100 pupils. The pupils attended five schools in Avram Iancu, Bogei, Carasau, Les and Suncuius, all village in Bihor, Romania, and were identified with higher school dropout risks. This paper proposes to present the partial results obtained at the end of the first period of the project implementation – the second semester of the 2010 / 2011 school year. The sample was represented by those 100 pupils from the above mentioned schools, who were included in Cognitive Therapy, implemented with the help of the project. The method consisted of analysing and comparing the pupils' school marks at the beginning and at the end of the relevant period. The results proved that, after one school semester, the pupils' marks remained rather unchanged, but in a few specific cases (schools or school subjects) small progresses were made. These results can, however, be seen as a significant success, because in education it is very difficult to obtain some spectacular improvements in such a short time and the most important aim of our project was to help those pupils to remain in the formal learning system so that that the positive conditions were created for their personal development. Key words: formal learning system, prevention, school dropout, school performance.

ABSTRACT Significant emphasis on data quality is placed on real-time drilling data for the optimization of drilling operations and on logging data for quality lithological and petrophysical description of a field. This is evidenced by huge sums spent on real time MWD/LWD tools, broadband services, wireline logging tools, etc. However, a lot more needs to be done to harness quality data for future workover and or abandonment operations where data being relied on is data that must have been entered decades ago and costs and time spent are critically linked to already known and certified information. In some cases, data relied on has been migrated across different data management platforms, during which relevant data might have been lost, mis-interpreted or mis-placed. Another common cause of wrong data is improperly documented well intervention operations which have been done in such a short time, that there is no pressure to document the operation properly. This leads to confusion over simple issues such as what depth a plug was set, or what junk was left in hole. The relative lack of emphasis on this type of data quality has led to high costs of workover and abandonment operations. In some cases, well control incidents and process safety incidents have arisen. This paper looks at over 20 workover operations carried out in a span of 10 years. An analysis is done on the wells’ original timeline of operation. The data management system is generally analyzed and a categorization of issues experienced during the workover operations is outlined. Bottlenecks in data management are defined and solutions currently being implemented to manage these problems are listed as recommended good practices.
