A system of systems integrates systems that function independently but are networked together for a period of time to achieve a higher goal. These systems evolve over time and have emergent properties. Therefore, even with security controls in place, it is difficult to maintain a required level of security for the system of systems as a whole because uncertainties may arise at runtime. Uncertainties can occur from internal factors, such as malfunctions of a system, or from external factors, such as malicious attacks. Self-adaptation is an approach that allows a system to adapt in the face of such uncertainties without human intervention. This work outlines the progress made towards security mitigation in system of systems using a generic autonomic management system to assist engineers in developing self-adaptive systems. The manuscript describes the proposed system design, its implementation as part of the Eclipse Arrowhead framework, and its functionality in a smart agriculture use case. The system is designed and implemented in such a way that it can be reused and extended for a variety of use cases without requiring major changes.

This paper explains political democratization in Post-Milosevic Serbia, utilizing two different accounts of the democratization process: one rooted in the rational choice framework and the other in structuralism. While rational choice explains the decisive role of political leadership in overcoming path dependence, the structuralist explanations show the transnational linkages that encourage democratization in the face of domestic setbacks. This particular debate between the two types of explanations represents the larger debate concerning the role of internal factors and external linkages in propelling democratization in transitional societies. The paper concludes by integrating the two sets of explanations offered by each theoretical perspective, in order to develop a coherent understanding of Serbia's democratization.   Full text available at: https://doi.org/10.22215/rera.v9i1.240

Abstrak. Remaja dengan penampilan fisik berjerawat yang tidak sesuai dengan gambaran idealnya, dikatakan memiliki kepercayaan diri tinggi apabila ia mampu menerima dengan realistis dan mensyukuri serta bertindak positif sedangkan kepercayaan diri rendah apabila remaja tersebut merasa tidak puas, malu, kecewa dan menolak keadaan dirinya. Jerawat atau acne vulgaris adalah peradangan folikel sebasea yang ditandai oleh komedo, papula, pustula, kista dan nodulus di wajah, leher, badan atas dan lengan atas. Jerawat cukup merisaukan karena berhubungan dengan menurunnya kepercayaan diri akibat berkurangnya keindahan wajah penderita. Penelitian ini bertujuan untuk menganalisis hubungan tingkat kepercayaan diri dengan jerawat. Jenis penelitian ini adalah korelasional dengan pendekatan waktu cross sectional (potong lintang). Subyek penelitian adalah siswa/i kelas X-XII SMA Negeri 7 Manado yang berjerawat dengan jumlah 90 responden yang dipilih dengan cara purposive sampling. Untuk menganalisis hubungan antara tingkat kepercayaan diri dengan jerawat digunakan teknik analisis Rank Spearman. Hasil penelitian menunjukkan bahwa nilai koefisien korelasi antara jerawat dengan kepercayaan diri sebesar -0,068, artinya jerawat dengan kepercayaan diri memiliki hubungan negatif dimana keeratan korelasinya sangat lemah (<0,20) sehingga dapat dikatakan tidak terdapat hubungan signifikan antara kepercayaan diri dengan jerawat (Sig=0,523). Artinya, kondisi fisik dalam hal ini jerawat bukan satu-satunya faktor yang mempengaruhi kepercayaan diri. Konsep diri, pengalaman, pendidikan merupakan faktor internal dan orang tua, teman sebaya dan masyarakat merupakan faktor eksternal yang bisa mempengaruhi kepercayaan diri. Responden yang memiliki kepercayaan diri tinggi walaupun berjerawat tidak berorientasi pada penampilan fisik semata, karena mereka merasa yakin akan kemampuan dan potensi dirinya pada hal-hal yang lain.Kata kunci: Remaja, Kepercayaan Diri, Jerawat.Abstract. Adolescents with acne in physical appearance that doesn’t like the ideal appearance, is said that have confidence when he can accept realistically, still feel grateful and act positively while low confidence if these adolescents are not satisfied, embarrassed, disappointed, and rejected themselves. Acne vulgaris is the inflammation of the sebaceous follicles characterized by comedones, papules, pustules, cysts and nodules on the face, neck, upper trunk and upper arms. Acne is troubling because it is related to the degradation of self confidence due to the beauty of the face.This study aimed to analyze the relationship between the level of confidence with acne. This type of study is correlational with cross sectional approach. The subjects are SMAN 7 Manado students who have acnes with 90 respondents chosen by purposive sampling. Spearman Rank analysis techniques is used to.The results showed that the correlation coefficient between acne with confidence at -0.068, meaning the relationship between acne and confidence is negative which the closeness of the correlation is very weak (<0.20) so that it canbe said there is no significant relationship between confidence with acne (Sig = 0.523). It means, the physical appearance in this case the acne is not the only factor affecting confidence. Self-concept, experience, education is the internal factors and their parents, peers and the community are the external factors that can affect confidence. Respondents with high self confidence eventhough have acnes are not oriented on their physical appearance alone, , because they feel confident in the ability and potential for him in other things.Keywords: Adolescents, Confidence, Acne.

Hemifacial Microsomia (HFM) is a term used to identify facial deformities associated with the development ofthe first and second pairs of branchial arches, characterized by underdevelopment of one half of the face. One typeof hemifacial microsomia is oculo-auriculo-vertebral dysplasia or Goldenhar syndrome.The incidence of HFM is 1:3500-1:7000 of live births and occurs in 1 case per 1000 children with congenitaldeafness. The ratio of boys to girls is 3:2. The etiology and type of inheritance is studied insufficiently. There are threepossible pathogenetic models: vascular abnormalities and hemorrhages in the craniofacial region, damage of Meckel'scartilage, and abnormal cell development of the cranial nerve crest. Environmental factors, maternal internal factors,and genetic factors (OTX2, PLCD3, and MYT1 mutations) may also cause the development of hemifacial microsomia.The article demonstrates a clinical case of hemifacial microsomia in a newborn boy from a mother with Z-21 inthe form of deformation of the left auricle with atresia of the auditory canal and "false" ears on the right, combinedwith congenital anomaly of heart (atrial septal defect) and brain (hypoplasia of the corpus callosum).Emphasis is placed on the need of involving a multidisciplinary team of specialists in the management of thispatient both in the neonatal period and in the system of subsequent follow-up.

Development of self-adaptive systems situated in open and uncertain environments is a great challenge in the community of software engineering due to the unpredictability of environment changes and the variety of self-adaptation manners. Explicit specification of expected changes and various self-adaptations at design-time, an approach often adopted by developers, seems ineffective. This paper presents an agent-based approach that combines two-layer self-adaptation mechanisms and reinforcement learning together to support the development and running of self-adaptive systems. The approach takes self-adaptive systems as multi-agent organizations and enables the agent itself to make decisions on self-adaptation by learning at run-time and at different levels. The proposed self-adaptation mechanisms that are based on organization metaphors enable self-adaptation at two layers: fine-grain behavior level and coarse-grain organization level. Corresponding reinforcement learning algorithms on self-adaptation are designed and integrated with the two-layer self-adaptation mechanisms. This paper further details developmental technologies, based on the above approach, in establishing self-adaptive systems, including extended software architecture for self-adaptation, an implementation framework, and a development process. A case study and experiment evaluations are conducted to illustrate the effectiveness of the proposed approach.

Objective: In this paper, the author explores a need for a greater understanding of the true nature of human–system interactions from the perspective of the theory of complex adaptive systems, including the essence of complexity, emergent properties of system behavior, nonlinear systems dynamics, and deterministic chaos. Background: Human performance, more often than not, constitutes complex adaptive phenomena with emergent properties that exhibit nonlinear dynamical (chaotic) behaviors. Methods: The complexity challenges in the design and management of contemporary work systems, including service systems, are explored. Examples of selected applications of the concepts of nonlinear dynamics to the study of human physical performance are provided. Results: Understanding and applications of the concepts of theory of complex adaptive and dynamical systems should significantly improve the effectiveness of human-centered design efforts of a large system of systems. Conclusion: Performance of many contemporary work systems and environments may be sensitive to the initial conditions and may exhibit dynamic nonlinear properties and chaotic system behaviors. Human-centered design of emergent human–system interactions requires application of the theories of nonlinear dynamics and complex adaptive system. Application: The success of future human–systems integration efforts requires the fusion of paradigms, knowledge, design principles, and methodologies of human factors and ergonomics with those of the science of complex adaptive systems as well as modern systems engineering.

AbstractIn a bid to reinforce the efforts of agricultural professionals within the domain of climate change studies and with particular emphasis on rural farmers in Nigeria, this chapter explores the mechanics for adoption of climate smart agricultural practices among rural farmers for an increased agricultural productivity. Climate-Smart Agriculture (CSA) is paramount to the success of farming activities today in the face of the menace of the impact of climate change. Climate Smart Agricultural Practice (CSAP) is one of the major keys that agricultural development approaches aimed at; to sustainably increase productivity and resilience, while also reducing the effects; as well as removing emissions of greenhouse gases. It is pertinent to note that most of the CSAPs adopted by the rural farmers in this study are conservation agriculture, use of organic manure, crop diversification, use of wetland (Fadama), planting of drought tolerant crops, relocation from climate risk zones, prayers for God’s intervention, and improvement on farmers’ management skills. This study divulged and showcased the import of CSAP in boosting agricultural yield and also highlights the bottlenecks inhibiting agricultural farming practices such as lack of practical understanding of the approach, inadequate data and information, lack of suitable tools at local and national levels, supportive and enabling policy frameworks, and socioeconomic constraints at the farm level. The study concluded by recommending an aggressive awareness and mobilization campaign to boost the adoption of CSAPs in Nigeria.
