The Moment

Due to pathologies or age-related problems, in some disabled people, motor impairment is associated with cognitive and/or visual impairments. This combination of limitations unfortunately leads to an inability to move around independently. Indeed, their situation does not allow them to use a conventional electric wheelchair, for safety reasons, and for the moment there is no other technological solution providing safe movement capacity. This lack of access to an autonomous travel solution has the consequence of weakening the intellectual, personal, social, cultural and moral development, as well as the life expectancy, of the people concerned. In this context, our team is working on the development of an optoelectronic system that secures the displacement of electric wheelchairs. This is a large project that requires the development of several functionalities such as: the anti-collision of the wheelchair with its environment, the prevention of falls from the wheelchair on uneven levels, and the adaptation of the system mechanically and electronically to the majority of commercially available electric wheelchair models, among others. In this article, we introduce our solution for detecting dangerous height differences, also called “negative obstacles”, through the creation of a dedicated sensor. This sensor works by optical triangulation and can embed several laser beams in order to extend its detection zone. It has the particularity of being robust in direct sunlight and rain and has a sufficiently high measurement rate to be suitable for the displacement of electric wheelchairs. We develop an adapted algorithm, and point out compromises, in particular between the orientation of the laser beams and the maximal speed of the wheelchair.

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.

The Stranger

Study abroad begins long before students leave their own shores. The moment that children enter daycare, nursery school, or kindergarten for the first time, they are in foreign territory, and all their antennae are out, testing, absorbing, learning. They begin to develop the first of their many multiple identities. They are no longer "Johnny" or "Sarah" whom everyone knows and loves at home, but Johnny or Sarah whom no one knows nor initially cares about, and they have to figure out what kind of a new identity they will develop so the danger zone becomes as safe as home.  Leaving familiar surroundings- the sounds, smells, safety, and food of home- and realizing, quite abruptly, that they must learn to adapt to the demands and needs of strangers, is the first and the most challenging "trip abroad" they will ever take. They will use the same set of skills, more mature, more polished (we hope) when they arrive on a foreign campus and move in with a host family or into an international dormitory.  Learning to make the journey with ease, whether it is on the first day of school or the day a plane drops one in a foreign field, is a necessary accomplishment. We have to make friends out of our peers; we have to gain the respect of our teachers; we have to develop curiosity and concern about the people around us. The stranger they seem, the more there is to learn. To fear diversity is to fear life itself. As the world becomes smaller and more integrated, the more crucial this accomplishment grows.

The land of PT. Hide Way Resort area 1.5 ha located in Ngawas village, Pasuruan district, the Province of East Java as at the moment is empty land and was planted apple, Eugenia, red pepper, carrot and pumpkin. It is located almost at the same position with Mount Bromo. This land will be used for accommodation/ 10 villas and 1 meeting room. We have to drive and reach this location and can see the apple and vegetable garden on mountain also very nice scenery we can see during passing this location. Also, we can see the natural village condition and warmest welcome from the people around the village. We can see very nice view after reaching the place by mountain view and hill view in cold temperature. Land and hill view on the area make more convenience to stay here. This kind of location can attract the tourist especially specific tourist who always searching the specific destination since it is not many kind of destination like this. The main concept is staying in natural village with traditional villa style and look like the traditional house in the past including the furniture inside and how to cook the food by burning wood. This kind of situation also completed with daily people around the village activities, traditional art show, transportation to Mount Bromo, golf and other activities. The marketing activities will be used the relationship of the owner with his channels abroad, community of specific tourism, you tube, social media and online travel agent. This opportunity is good to be developed in the future since many inquiry for this kind of specific tourism, increase the economy level of the people around and create more working opportunity.

The fourth chapter reviews the meanings and interpretations that the spectators associated with the keywords and motifs at the moment of their reception in performance. One of the questions examined in the course of investigation is how the process of dissemination of ideas and attempts to awake a national community were juxtaposed with alternatives, often by negatives too, produced in the same space. Swadeshi performance, in its space, attached a new meaning to the notion of nationhood. A modification was introduced in this dissemination, causing the idea of violence to be added to the notion of nationhood. This seeped into the mental habits of the people and became their custom in the long term, thereby engendering a nationhood that had a close nexus with violence.

This chapter begins with an account of necessity's story. It illustrates the moment of receding crisis in American life that produced Franklin Roosevelt's warning that “necessitous men are not free.” The chapter explains how necessity can produce dictatorship, because the people are willing to allow whatever it takes to solve their immediate needs. It looks into the theory that a president might suspend the constitutional order like a Roman dictator in order to post hoc political accountability. It also analyzes the misguided belief that constitutional systems can function in the so–called “states of exception,” which misconstrues the relation between rules and exceptions. The chapter explains “rule skepticism” that results from believing that if rules do not determine responses to new applications then rules cannot function as constraints.

Dairy products are of great socio-economic importance in Romania today. These products have both nutritional and economic importance. The market is the economic category of commodity production in which it expresses the totality of the sale-purchase acts viewed in an organic unit with the relations it generates and in connection with the space in which it takes place. The market originated a long time ago, being related to the moment when, in order to satisfy their existential needs, "discovered" and increasingly "conscious", the people exchanged between them, respectively collectivities, the surpluses held by each individual - individually or collectively. The exchange, set up as a means of realizing its own interests, has seen various forms and has evolved continuously, being still the foundation of all the economies of the world. The market has grown based on the amplification and diversification of human needs. The satisfaction of these needs is given by the close link between producers and consumers.

Since the appearance of the term visual literacy in the second half of the 20th century, many authors have spoken of visual competencies. These competencies are acquired through the use of visual language and an understanding that the use of human and cultural capabilities makes people free to create and interpret messages. Furthermore, since the incorporation of new technologies, any prosumer (producer and consumer) can generate visual communication. This research develops and validates a questionnaire proposal to observe visual literacy in users of new technologies to analyze the state of literacy of image prosumers. This questionnaire is composed of 61 items that are related to habits in the reception, consumption, and production of images; the capacities of perception and visual interpretation; and the cultural aspects of the people who use images as a communicative vehicle. The purpose of this proposal is to facilitate the analysis of common characteristics that explain the moment in which people live from the point of view of visual communication and the cultural differences that are related to this field.

Intense Debate

The emigration of Jews from Morocco to Israel, in particular, is the subject of intense debate among historians, signaling the difficulty of telling a unified story of this moment. I want to contribute to this debate by showing that the combining and often opposing forces of Colonialism and Zionism were the main factors that triggered these migrations, in a period of rising Moroccan nationalism. But those forces were also seen as opportunities by some migrants to seize the moment to better their fate and realize their dreams. If we cannot assess every migrant story, I want here to suggest through my family’s experience and memory and other collected oral histories, how we could intertwine those memories to a larger narrative to shed more light on this history. The push and pull forces that led to Moroccan Jewry’s migrations and post-colonial circulations between the 1940s and 1960s were the result of a reordering of the complex relationships between the different ethnic and religious communities well before the migration took place. The departures of the people interviewed for this study are inscribed in both the collective and family dynamics, but were organized in secret, away from the gaze of the others, particularly that of non-Jewish neighbors. Their belonging to a sector of the colonial world, while still prevalent in their narratives, is blurred by another aspect of post-colonial life in Morocco, that is the cultural/education nexus. Depending on where one has been educated and socialized, the combined effects of Colonialism and Zionism strongly impacted the time of their departures and the places they went to.

Many hypotheses have been developed to explain aging and age-related neurodegenerative disorders; one of the most compelling is the role of oxidative stress to induce changes in protease activity in brains of patients of Alzheimer’s disease and prion disease. At the moment however, there is no clear answer how protein degradation may be achieved in the brain. We have observed that several metal compounds can degrade proteins in the presence of hydrogen peroxide, and elucidated the reaction scheme based on the new theoretical point for the reactivity of a metal-peroxide adduct with η1-coordination mode. In this article we would like to point out the importance of a copper(II)-peroxide adduct to promote neurodegenerative diseases such as prion disease and amyotrophic lateral sclerosis through its oxidative protease function.

Abstract Background. A leukaemic evolution is evident in less than 50% of myelodysplastic patients. They can often die of age-related problems which are independent of myelodysplastic syndrome (MDS) itself, and the best therapy is difficult to define for this group of old patients, in which aggressive strategies are at high risk and supportive care can constitute the most useful option. A systematic analysis of causes of death is so far lacking. Aim of the work. To analyse the prognosis of a large group of myelodysplastic syndromes with particular reference to the causes of death. Patients and methods. From January 1999 to June 2005, data from 783 new cases of MDS were prospectively recorded into the Piedmont MDS register through our web site. Thirty two and 68 cases were excluded because RAEB-t and CMMoL respectively. The remaining 680 patients, who are the object of the present analysis, can be subdivided according to the WHO classification as follows: 99 RAEB-II; 160 RAEB-I; 104 RCMD; 317 MDS other than RAEB and RCMD. Data regarding co-morbidity and IPSS score are available for 457 and 404 patients respectively. At the moment of the analysis, 157 deaths were recorded and causes of death were registered for 153 patients. Results. Median age was 73 (range 27–95), with 151 patients (22%) older than 80. One or more co-morbidities were present at diagnosis in 399/457 (87%). The prognostic role of both IPSS scoring system and WHO classification were confirmed. The causes of death were subdivided as follows: complications due to cytopenia and/or leukaemic transformation in 57 patients (37%); infections in 20 patients (13%); other age or co-morbidity related causes in the remaining 76 patients (50%). No significant differences of causes of death were seen according to sex, while deaths from unrelated causes increased with increasing age from 29% under 60 years up to of 61% over 80 years (test for linear trend: p=0.02). Deaths due to cytopenia, and/or leukaemic transformations, and/or infections were more frequent in patients with no co-morbidities (75%), while no differences were seen according to the number of co-morbidities: 44%, 39% and 55% for patients with respectively one, two and three associated diseases. A significant relationship was evident between diagnostic subgroups and deaths from unrelated causes: 21% for RAEB-II; 51% for RAEB-I; 53% for RCMD; 76% for MDS other than RAEB and RCMD (p<0.01). A similar relationship was evident between IPSS score and causes from unrelated causes: 27% for score int-2/high and 60% for score low/int-1 (p=0.01). Conclusions. The prognostic analysis of this group of MDS patients with attention to the causes of dearth suggest that the majority of patients die of unrelated causes. Age and co-morbidities should play a major role in defining the treatment strategy of this group of patients. Anti-leukaemic treatments should therefore be limited to a small group of patients with diagnosis of RAEB and high IPSS score. An improvement in supportive treatment should be useful for the majority of patients.
