Mass and uncontrolled immigration as a threat to the civil, legal and civilizational stability in Western European countries and Russia
Authors: Yengibaryan R. V. 
Published: December 2019

Introduction. Following the collapse, or rather self-liquidation, of the Soviet Union-USSR world events began to develop at a kaleidoscopic speed. Europe, Russia and the United States ceased to be central actors in global politics. Huge civilization countries such as China, India and the African continent broke into global politics with ever-increasing power. The united bloc of Islamic countries began to make aggressive claims to the entire world community, and especially to the countries of Christian civilization. And the most important and unexpected thing is that the peoples, nations, communities everywhere began to return to their civilizational, religious and spiritual roots.Materials and methods. Various methods such as comparative law, systemic, logical analysis and other methods were used in writing this article.The results of the study. The attempt to globalize the world by the socio-political criterion “capitalism socialism” failed. The world community, or rather its political, economic and intellectual elite, was given a clear message: ideologies of all kinds communism, fascism, nationalism, socialism eventually undergo transformation, split into sub streams and practically disappear, but the world religions and civilizations remain.Discussion and conclusion. The world globalized spontaneously and naturally, with financial, economic, political and technological dimensions playing the major role. At the same time globalization laid the foundation of new contradictions among countries that enjoy different social, economic levels of development and belong to various civilizations. Moreover, the interests of civilizations living in different time dimensions began to clash, like Islam that lives in 1441 and other countries that have been living in the 21st century for the second decade. The ideology of multiculturalism both in Western Europe and in the USA turned out to be unrealizable in practice, just like the communist ideology that has sunk into oblivion.
Politics and State: Two Sides of the Same Phenomenon
Authors: Vorobiev Valery P. , Iliev Roman L. 
Published: December 2019

Introduction. The centuries-old history of the state and political protest movements as their driving force highlights an interesting pattern. Participants, initiators, and leaders are not interested in the underlying causes of protests. The forms and content of management, socio-political systems are changing but in all situations a narrow circle of people continues to make all important decisions.Materials and methods. The study used comparative legal and systemic methods, various materials.The results of the study. Political decisions overtly or covertly threaten performers of these decisions with punishment for non-compliance. However, as a rule only they always bear suffering and losses for erroneous decisions.Discussion and conclusion. According to Hegel a political decision is based “on subjective goals and opinions, on subjective feeling and private conviction that lead to the destruction of internal morality, integrity and conscience, love and law in relations between individuals, on the one hand, and public order and state laws not limited by legal norms and not restrained by public institutions, on the other”. The well-known scientists Weber, Duverger, Bentham and many others also held the same opinion that politics expresses “the desire of those in power to possess it, which provides them with control over society and personal benefits”. The term “politics” in its modern sense has arisen due to a misunderstanding. The prestige of Aristotle was used to give the befitting justification to the right of the sovereign to make decisions according to his preference and whim. In the 3rd century A.D. Aristotle used in his work the word “politics”, which at that time meant “state” (“polity” is the rule of the majority; Aristotle used it as the name of a specific form of state republic). Now, in many contexts, the word “politics” is used along with the terms “political system” or “state”, and the lack of knowledge about patterns is replaced by describing past or fictional events in the lives of the mighty people and fortunetelling about future events.

Published: December 2019

Ketersediaan dan kualitas hijauan yang baik menjadi salah satu pendukung keberhasilan kegiatan penangkaran. Penelitian ini bertujuan untuk mengetahui produktivitas serta kualitas rumput pakan anoa terutama di musim kemarau yang mampu mendukung populasi anoa di penangkaran Anoa Breeding Centre pada kondisi pra budidaya. Penelitian dilaksanakan dienam lokasi yang menjadi tempat pengambilan rumput pakan anoa di sekitar penangkaran yaitu Mapanget, Matungkas dan Kairagi. Metode yang digunakan dalam pengukuran produktivitas adalah dengan membuat plot ukuran 1 x 1 meter dibiarkan selama 20 hari selama tiga kali ulangan untuk dilakukan pemotongan dan penimbangan. Kualitas rumput pakan diketahui dengan melakukan analisis proksimat. Hasil pengukuran di enam lokasi menunjukkan bahwa produktivitas rumput pakan sebesar 34,15 kg/hari, jika konsumsi perhari untuk anoa diperkirakan 5-10 kg/hari maka hanya dapat memenuhi 3-4 ekor anoa. Beberapa alternatif untuk memenuhi kebutuhan pakan anoa dapat dilakukan dengan memberikan tambahan hijauan maupun sayuran serta melalui penanaman rumput unggul di sekitar penangkaran disertai dengan pemupukan dan pemeliharaan yang baik. Berdasarkan kualitasnya diperoleh bahwa rumput pakan yang diberikan pada anoa dapat memenuhi kebutuhan protein anoa sebesar 11-16/100 g setiap harinya. Sedangkan kebutuhan harian kalsium maupun phosphor belum cukup terpenuhi. Sehingga diperlukan pakan tambahan dan mineral yang dapat mencukupi kebutuhan mineral bagi anoa di penangkaran.

This study was aimed to evaluate the in vitro Centrosema pubescens response treated with sulfur water and sheep manure. The experiment was conducted at Agrostology Laboratory, Department of Animal Nutrition Science, Faculty of Animal Husbandry, Sam Ratulangi University Manado. Randomized group design of 2 x 5 factorial patterns with three repetitions based on the rumen liquid collecting time was used in this research. There were two factors in this experiment; sheep manure and sulfur water. The first factors consisted of 0 ton/ha manure (A1) and 25 ton/ha manure (A2). The second factor was sulfur water that divided into 5 levels; 0% (B1), 25% (B2), 50% (B3), 75% (B4) and 100% (B5). Variables measured in this research were dry matter digestibility (DMD), organic matter digestibility (OMD), ammonia (NH3) and Volatile Fatty Acid (VFA). In vitro nutritional evaluation performed with all variables showed both factors (sulfur water and sheep manure) had significant differences (p < 0.001) and had no significant effect (p < 0.05) on each variable. Interaction of both factors was very significant (p < 0.01) ontotal VFA and DMD. From this study it can be concluded that production of NH3, VFA, total DMD and OMD showed an optimal result if treated with 25 ton/ha of sheep manure and 50% sulfur water (39.25 ppm).

The research material used was neem leaves, shelled corn, storage containers and analytical equipment. Neem leaves are given in the form of flour with a size of 60 mesh while corn used in shell corn with water content and aflatoxin content before storage are 20% and 110 ppb respectively. Shelled corn was used as much as 1 kg for each treatment and stored in modified woven bags for 4 weeks. The research method is an experimental method using a completely randomized design (CRD), with 4 treatments and 4 replications. The treatments were the percentage of neem leaf flour addition in shelled corn, the four treatments were treatment A (0% neem leaf flour), B (2.5% neem leaf flour), C (5% neem leaf flour), and D ( 7.5% neem leaf flour). Parameters measured were percentage of damaged seeds, percentage of moldy seeds, moisture content and aflatoxin content. The results of the study showed that the treatment had a highly significant effect (P<0.01) on% of damaged seeds, % of moldy seeds, and aflatoxin content on shelled corn during storage. The administration of neem leaf flour at 2.5% level was able to maintain the quality of shelled corn during storage, where the aflatoxin content could decrease from 110 ppb before storage to 34,25 ppb after being stored for 4 weeks.

Social Determinants of Health: If You Aren't Measuring Them, You Aren't Seeing the Big Picture
Authors: Rethorn Zachary D. , Cook Chad , Reneker Jennifer C. 
Published: December 2019

Clinicians often assume that interventions directly influence the recovery of patients with musculoskeletal impairments. In reality, other factors may influence recovery more than the direct treatment provided. The most powerful factor may be upstream effects such as economic stability, education, health and health care, neighborhood and built environment, and social and community context—commonly termed the social determinant of health (SDH). Although a single empirical pathway linking the collective impacts of the SDH to musculoskeletal health outcomes has not been established, our view is that they exert tremendous effects on physical therapy outcomes in practice and research. In this Viewpoint, the authors discuss the SDH and argue that recognizing the impact of SDHs on health behavior is vital to seeing the whole picture related to musculoskeletal recovery.

Erythema Multiforme Major caused by topical Imiquimod
Authors: Edelman Alexandra , Jackson Mark , Knable Alfred 
Published: December 2019

Erythema multiforme (EM) is an acute, self-limited inflammatory skin disease that is associated with an immune reaction to various triggers, such as herpes simplex virus, Mycoplasma pneumoniae, and medications. Topically applied medications are a rare cause of EM or EM-like eruptions. We report one patient with EM major from imiquimod 5% topical cream. After reviewing the relevant literature, we found eight cases of erythema multiforme induced by topical imiquimod. Of the eight cases of Imiquimod-induced EM, seven patients had a significant local reaction that subsequently led to the more distant cutaneous manifestations of erythema multiforme. Because Imiquimod is a commonly used topical treatment for a variety of dermatologic conditions, clinicians must be aware of this rare but serious complication. Furthermore, patients with an exuberant local reaction to imiquimod may be at higher risk of developing EM.
The Need for Objective and Remote Tracking of Chronic Skin Diseases
Authors: Afanasiev Olga K , Tabata Mika , Ko Justin M 
Published: December 2019

Importance: Managing chronic skin disease is often frustrating for both providers and patients, sometimes resulting in delayed diagnosis, inadequate therapy, and inconsistent care.Objective: This study performs stakeholder analyses to identify unmet clinical needs in chronic skin disease management. Methods: Survey of 33 providers and 25 patients at a Stanford Health Care Dermatology department.Results: When evaluating a chronic skin condition such as psoriasis, 79% of dermatologists rely solely on subjective documentation (gestalt, body surface area, descriptive exam). Objective documentation (photographs or scoring assessment tools) is used by 21% of providers upon initial assessment and by 7% of providers to assess change in disease between office visits. While 83% of providers were comfortable assessing change in disease severity based on prior document by oneself, only 31% were comfortable assessing change based on prior documentation by another provider (p <0.001). Dermatologists expressed the need for better documentation modality in clinic (94%), and in between office visits by patients (91%). While 90% of patients reported it is moderately to extremely important to track their disease, only 16% of patients consistently do. Most patients preferred to monitor their disease at home (92%) using cameras (80%) or by smartphone (59%). Patients were willing to spend 5-30 minutes weekly to monthly to document their disease.Conclusions and Relevance: This study identifies that dermatologists and patients need a solution that objectively and remotely monitors chronic skin diseases to optimize treatments, empower patients, and provide more cohesive care in a complex healthcare system.
Adolescent Sun Protection Behaviors and Beliefs
Authors: Nazarian Roya S. , Pan Michael , Utz Sarah , Geller Lauren 
Published: December 2019

The incidence of melanoma and non-melanoma skin cancer has increased among children and adolescents. Studies in the pediatric population have shown low rates of sun protection with modest improvement over the past several decades. This descriptive study characterizes photo protection behaviors and knowledge, specifically among pediatric dermatology patients in order to identify gaps in knowledge and guide discussion for health providers. Adolescents ages 12 to 20 completed surveys, which evaluated use of sun protection, beliefs about tanning and skin cancer, and sources of information. Results demonstrated that only nine percent of participants reported daily, year-round use of sunscreen. The majority (71%) reported use only during the summer months or when spending prolonged periods of time outdoors. Rates of indoor tanning were lower than reported in the literature, with only one percent reporting indoor tanning use. The majority of patients reported family members were the primary source of sun protection education. The authors conclude that while adolescents receiving care in the pediatric dermatology setting demonstrate sufficient knowledge about skin cancer prevention, adherence remains low. This study identified family members as the primary source of sun protection knowledge. Dermatologists should consider increased parental education to improve adolescent patient behavior.
