Heating with wooden chips would provide a significantly cheaper energy production alternative for the local governments in heating their facilities and in district heating as well. The raw material should be available in the appropriate quality, quantity and at the right time. This type of heating requires the well-organized and joint work of the forestry, transporting, processing and receiving plants. This activity might be realized in the form of non-profit clusters. In order not to suffer any losses, the participants of the product path should carry out a very careful planning regarding the factors appearing in heating with wood but missing from gas heating. One such critical element is the transportation distance which might make the basically cost-efficient wooden chip-based heating process significantly more expensive. One of the main findings of my paper is that the transportation distance should be at most 23 kilometers for the wooden chips to be worth (economical) using against gas. From the viewpoint of practical use, this can be interpreted as the distance between the forestry and heatproducing units. By determining the constant and varying costs of transporting and chopping and from calculating the initial contribution, I concluded that the profit-making capacity of the product path would be sufficient for an energy-related investment. According to my calculations, by remaining within the economical transporting distance of 23 kilometers, such long-term savings might be achieved compared to gas heating which would partly cover the establishment of a biomass-based power plant or heating plant.

Entering into the new field of business is not an easy go. One has to do market research, to identify the gap, to identify the product/service to be offered, and to target the right customer segment. After doing the required research, the next step is to make decisions on plant location, layout and then set up.  Assessment of funds required for capital as well as revenue expenditure, procurement of machinery and other materials also take substantial amount of efforts. Searching for vendors and finalizing the right one are few other issues. After having worked successfully for more than 30 years in Bali in the field of sesame seeds and oil business Harsh was standing on a crossroad in 2011. Rising prices of sesame oil resulted in shift in customers’ taste and preferences towards refined oil. Moreover entry of big players at a large scale of operations and rise in price of raw material (sesame seeds) made survival tough. He had a number of options, one to continue with existing business at different scale of operations. Two, enter another business? Three, what business, Four, which place? The case talks about Harsh’s journey to new business, his choice and then the result.

Energy-from-Waste plants using grate-based systems have gained world-wide acceptance as the preferred method for the sustainable treatment of waste. Key factors are not only the reduction of waste volume and mass and the destruction or separation of pollutants but also the efficient production and use of energy (electricity, district heating/cooling, process steam), compliant disposal and the recovery of resources from combustion residues (e.g. metals, rare earths). International requirements relating to energy efficiency and materials recovery by means of thermo-recycling in Energy-from-Waste plants call for the continuing development and optimization of existing technologies and concepts. The technologies and processes for the recovery of reusable materials from dry-discharged bottom ash and from filter ash point to the key role that Energy-from-Waste plants are able to play in the efficient conservation of resources. It is primarily thermal treatment with dry discharge and subsequent processing of the bottom ash fractions that enables Energy-from-Waste plants to justify their status as universal recyclers. In addition to recovery of the energy inherent in the waste, the treatment of dry-discharged bottom ash is an important contribution to compliance with raw material and climate policies and to the promotion of closing the material cycle in general. Furthermore, dry bottom ash discharge represents a further step towards waste-free operation and “after-care-free” landfills. This paper documents the potential of Energy-from-Waste plants for the recovery of resources and provides examples of recent developments and large-scale implementations of innovative recovery technologies in Europe.

Act 50 of 2013 has served as a new and large scale impetus for both public bodies and local governments regarding information security in Hungary. This naturally means an increased need for professionals on the field. The National University of Public Services has become an institution that may very well be capable of training the required number of professionals. The aforementioned act has been amended by an implementing regulation (no. 41/2015) and as a result the system as a whole has changed regarding information security.3 This paper aims to highlight any problems that shall be addressed and solved as quickly and swiftly as possible. Basic skills and areas that shall be improved will also be in focus as well as processes that are vital in order to realize the actual situation of information security. Without the possibility to continuously determine the actual situation and without the means to assess such situation, the probability of deterring from the right path increases. Further challenges that this area has to face actually originate from situation assessment and the determination of the “correct” path. The theoretical model (to be presented), developed during the previous years, provides quick and swift possibilities to intervene in such areas if need be. The model guarantees a way to give feedback and is able to set up a communication channel that may be used to support the whole structure on the long run in a cost efficient manner. It is capable to provide feedback from numerous areas of the system while maintaining its structure and applying clarity or additional precision where necessary. Its real advantage is that the whole system (of institutions and/or public bodies) may use it as a single institution or body would not be able to realize or develop the model in its entirety.

Abstract—The coronavirus has fully motivated a number of regions in Indonesia to implement Large-Scale General Restrictions (PSBB). This policy may be the right solution. However, it also brings with it a recent dilemma embracing women. PSBB has influenced individuals to limit their physical mobility and move them to use high dependence on technology platforms including the web or social media. The intensity and repetition of social media use leads to online aggression compared to the case of women. The Jakarta Women's Legal Aid Institute noted that there were 30 cases of online violence against women in Indonesia in March and April 2020. Unfortunately, this number continues to increase from year to year. Many forms of online sex-based violence exist and most of them aim to intimidate, humiliate, and dominate women. Some of them are online sexual harassment, fear of sharing personal content with exploitation themes, dating violence, and online extortion. Surprisingly, not all women in Indonesia understand and report these forms of violence to the National Commission for the Protection of Women or related agencies due to the lack of information and socialization from local governments during the pandemic. As a result, this issue marks a long list of solutions involving governments and the private sector to make online violence worse. This paper will explicitly show the importance of eradicating online violence against women during the Coronavirus in Indonesia. Courage to speak is needed. Community support to exercise their right to vote is very important to voice positive things and stop violence against women. Keywords: covid-19,gender, Indonesia, online violence, woman Abstrak—Virus corona telah mendorong sejumlah daerah di Indonesia untuk menerapkan Pembatasan Sosial Berskala Besar (PSBB). Kebijakan ini mungkin bisa menjadi solusi yang tepat. Namun, hal tersebut dapat menjadi dilemma bagi perempuan. PSBB telah mempengaruhi setiap individu untuk membatasi mobilitas fisik dan menggerakkan masyarakat untuk memiliki ketergantungan tinggi terhadap teknologi, seperti internet atau media sosial. Jumlah intensitas dan penggunaan media social yang semakin meningkatkian harinya, mengarah kepada agresi online terhadap perempuan. Lembaga Bantuan Hukum Perempuan Jakarta mencatat ada 30 kasus kekerasan online terhadap perempuan di Indonesia pada Maret dan April 2020. Sayangnya, jumlah ini terus meningkat dari tahun ketahun. Ada banyak bentuk kekerasan berbasis seks online dan mayoritas diantaranya bertujuan untuk mengintimidasi, mempermalukan, untuk membagikan konten pribadi yang mengarah kepada eksploitasi, kekerasan dalam berpacaran, dan pemerasan online. Anehnya, tidak semua perempuan di Indonesia memahami dan melaporkan bentuk-bentuk kekerasan tersebut ke Komnas Perempuan atau instansi terkait karena minimnya informasi dan sosialisasi dari pemerintah daerah selama pandemi. Akibatnya, masalah ini menandai daftar panjang dan solusi terhadap buruknya kekerasan online yang melibatkan pemerintah dan sektor swasta. Tulisan ini secara eksplisit akan menunjukkan pentingnya pemberantasan kekerasan online terhadap perempuan selama virus Corona di Indonesia. Dibutuhkan keberanian untuk berbicara. Dukungan masyarakat untuk menggunakan hak pilihnya sangat penting untuk menyuarakan hal-hal positif dan menghentikan kekerasan terhadap perempuan. Kata kunci: covid-19, gender, Indonesia, kekerasan online, perempuan

One scenario put forward by researchers, political commentators and journalists for the collapse of North Korea has been a People’s Power (or popular) rebellion. This paper analyses why no popular rebellion has occurred in the DPRK under Kim Jong Un. It challenges the assumption that popular rebellion would happen because of widespread anger caused by a greater awareness of superior economic conditions outside the DPRK. Using Jack Goldstone’s theoretical expla-nations for the outbreak of popular rebellion, and comparisons with the 1989 Romanian and 2010–11 Tunisian transitions, this paper argues that marketi-zation has led to a loosening of state ideological control and to an influx of infor-mation about conditions in the outside world. However, unlike the Tunisian transitions—in which a new information context shaped by social media, the Al-Jazeera network and an experience of protest helped create a sense of pan-Arab solidarity amongst Tunisians resisting their government—there has been no similar ideology unifying North Koreans against their regime. There is evidence of discontent in market unrest in the DPRK, although protests between 2011 and the present have mostly been in defense of the right of people to support themselves through private trade. North Koreans believe this right has been guaranteed, or at least tacitly condoned, by the Kim Jong Un government. There has not been any large-scale explosion of popular anger because the state has not attempted to crush market activities outright under Kim Jong Un. There are other reasons why no popular rebellion has occurred in the North. Unlike Tunisia, the DPRK lacks a dissident political elite capable of leading an opposition movement, and unlike Romania, the DPRK authorities have shown some flexibility in their anti-dissent strategies, taking a more tolerant approach to protests against economic issues. Reduced levels of violence during periods of unrest and an effective system of information control may have helped restrict the expansion of unrest beyond rural areas.

This book provides an authoritative assessment of how immigration is reshaping American politics. Using an array of data and analysis, it shows that fears about immigration fundamentally influence white Americans' core political identities, policy preferences, and electoral choices, and that these concerns are at the heart of a large-scale defection of whites from the Democratic to the Republican Party. The book demonstrates that this political backlash has disquieting implications for the future of race relations in America. White Americans' concerns about Latinos and immigration have led to support for policies that are less generous and more punitive and that conflict with the preferences of much of the immigrant population. America's growing racial and ethnic diversity is leading to a greater racial divide in politics. As whites move to the right of the political spectrum, racial and ethnic minorities generally support the left. Racial divisions in partisanship and voting, as the book indicates, now outweigh divisions by class, age, gender, and other demographic measures. The book raises critical questions and concerns about how political beliefs and future elections will change the fate of America's immigrants and minorities, and their relationship with the rest of the nation.

Justice that has not existed and is apparent among the disabilities in Indonesia is very large and spread in the archipelago is very large, making the issue of equality is a very important thing especially with the publication of the Disability Act No. 8 of 2016 at the beginning of that year. Only a few provinces that understand properly and well on open and potential issues and issues will affect other areas including the increasingly growing number of elderly people in Indonesia due to the increasing welfare of the people. The government of DKI Jakarta, including the most concerned with disability, from the beginning has set a bold step to defend things related to disability, including local governments in Solo, Bali, Makassar and several other areas. Leprosy belonging to the disability community has a very tough marginalization, the disability that arises from leprosy quite a lot, reaches ten percent more and covers the poor areas of Indonesia, such as Nusa Tenggara Timur, Papua, South Sulawesi Provinces and even East Java and West Java and Central Java Provinces. If we compare again with the ASEAN countries we also do not miss the moment in ratifying the CRPD (Convention of Rights for People with Disability) into the Law of Disability No. 8 of 2016 which, although already published but still get rejections in some sections because do not provide proper empowerment and rights equality. The struggle is long and must be continued to build equal rights in all areas, not only health and welfare but also in the right of the right to receive continuous inclusive education.

Background: Shear wave electrography (SWE) is a novel non-invasive imaging technique which demonstrate tissue elasticity. Recent research evaluating the elasticity properties of normal and pathological tissues emphasize the diagnostic importance of this technique. Aims: Polycystic ovarian syndrome (PCOS), which is characterized by menstrual irregularity, hyperandrogenism, and polycystic overgrowth, may cause infertility. The aim of this study was to evaluate the elasticity of ovaries in patients with PCOS using SWE. Methods: 66 patients diagnosed with PCOS according to the Rotterdam criteria (PCOS = group I) and 72 patients with non-PCOS (Control = group II), were included in the study. Demographic and clinical characteristics of the participants were recorded. Ovarian elasticity was assessed in all patients with SWE, and speed values were obtained from the ovaries. The elasticity of the ovaries was compared between the two groups. Results: While there were statistically significant differences between the groups in body mass index (BMI), right and left ovarian volumes, luteinizing hormone and testosterone levels (p<0.05), no significant differences were found between groups I and II in the velocity (for the right ovary 3.89±1.81 vs. 2.93±0.72, p=0.301; for the left ovary 2.88±0.65 vs. 2.95±0.80, p=0.577) and elastography (for the right ovary 36.62±17.78 vs. 36.79±14.32, p=0.3952; for the left ovary 36.56±14.15 vs. 36.26±15.10, p=0.903) values, respectively. Conclusion: We could not obtain different velocity and elastography values from the ovaries of the patients with PCOS using SWE. Therefore, further large-scale studies are needed to elucidate this issue.

In June 2008, the U.S. Supreme Court ruled that the Second Amendment to the U.S. Constitution guarantees an individual the right to keep and bear arms. Two years later, this decision was also made applicable to state and local governments. Today, seven U.S. states have provisions allowing the carrying of concealed weapons on their public senior high school campuses. This article, introduced by a brief comment on the Second Amendment’s legal and academic history, traces several recent developments of legal change. It discusses relevant arguments and attitudes towards guns on campus, and explores issues of future concern for public colleges and universities within the realm of firearms and campus safety.

Since invasive alien species are one of the main causes of biodiversity loss in the region and thus of changes in ecosystem services, it is important to find the best possible solution for their removal from nature and the best practice for their usability. The aim of the study was to investigate their properties as components of wood-plastic composites and to investigate the properties of the wood-plastic composites produced. The overall objective was to test the potential of available alien plant species as raw material for the manufacture of products. This would contribute to sustainability and give them a better chance of ending their life cycle. One of the possible solutions on a large scale is to use alien wood species for the production of wood plastic composites (WPC). Five invasive alien hardwood species have been used in combination with polyethylene powder (PE) and maleic anhydride grafted polyethylene (MAPE) to produce various flat pressed WPC boards. Microstructural analyses (confocal laser scanning microscopy and scanning electron microscopy) and mechanical tests (flexural strength, tensile strength) were performed. Furthermore, measurements of density, thickness swelling, water absorption and dimensional stability during heating and cooling were carried out. Comparisons were made between the properties of six WPC boards (five alien wood species and mixed boards). The results showed that the differences between different invasive alien wood species were less obvious in mechanical properties, while the differences in sorption properties and dimensional stability were more significant. The analyses of the WPC structure showed a good penetration of the polymer into the lumens of the wood cells and a fine internal structure without voids. These are crucial conditions to obtain a good, mechanically strong and water-resistant material.
