The proliferation of IoT devices has presented an unprecedented challenge in managing device identities securely and efficiently. In this paper, we introduce an innovative Hybrid Blockchain-Based Approach for IoT Identity Management that prioritizes both security and efficiency. Our hybrid solution, strategically combines the advantages of direct and indirect connections, yielding exceptional performance. This approach delivers reduced latency, optimized network utilization, and energy efficiency by leveraging local cluster interactions for routine tasks while resorting to indirect blockchain connections for critical processes. This paper presents a comprehensive solution to the complex challenges associated with IoT identity management. Our Hybrid Blockchain-Based Approach sets a new benchmark for secure and efficient identity management within IoT ecosystems, arising from the synergy between direct and indirect connections. This serves as a foundational framework for future endeavors, including optimization strategies, scalability enhancements, and the integration of advanced encryption methodologies. In conclusion, this paper underscores the importance of tailored strategies in shaping the future of IoT identity management through innovative blockchain integration.

Context: Genuine community participation does not denote taking part in an action planned by health care professionals in a medical or top-down approach. Further, community participation and health education on breast cancer prevention are not similar to other activities incorporated in primary health care services in Iran. Objective: To propose a model that provides a methodological tool to increase women's participation in the decision making process towards breast cancer prevention. To address this, an evaluation framework was developed that includes a typology of community participation approaches (models) in health, as well as five levels of participation in health programs proposed by Rifkin (1985&1991). Method: This model explains the community participation approaches in breast cancer prevention in Iran. In a 'medical approach', participation occurs in the form of women's adherence to mammography recommendations. As a 'health services approach', women get the benefits of a health project or participate in the available program activities related to breast cancer prevention. The model provides the five levels of participation in health programs along with the 'health services approach' and explains how to implement those levels for women's participation in available breast cancer prevention programs at the local level. Conclusion: It is hoped that a focus on the 'medical approach' (top-down) and the 'health services approach' (top-down) will bring sustainable changes in breast cancer prevention and will consequently produce the 'community development approach' (bottom-up). This could be achieved using a comprehensive approach to breast cancer prevention by combining the individual and community strategies in designing an intervention program for breast cancer prevention.

In order to recommend future national policy directions on energy supply and consumption and to suggest energy technological priorities to be developed, comprehensive energy models have been developed through this study in a sense of strategic and systematic approach. The “energy input-output model” has been formulated to analyze the mutual impacts between energy consumption patterns and industrial structures and to calculate energy intensities of industrial sectors. The long-term energy demands to the year 2000 were forecasted by using multi-regressional method and the optimal energy flow balances for five-year interval have been studied by using the “energy linear programming model” being took full account of interfuel substitutability and technology.

Computer aided engineering (CAE) is a systematic approach to develop a better product/application with maximum possible options and minimum transition time. This paper presents a comprehensive feasibility analysis of various CAE techniques for evaluation and optimization of power electronic converters and systems. Different CAE methods for analysis, design, and performance improvement are classified. In addition, their advantages compared to the conventional workbench experimental methods are explained in detail and through examples.

Quite high prevalence of acute and chronic complications of calcaneal fractures has been reported. Acute complications include blisters, wound necrosis or infection. Late complications include subtalar arthritis, calcaneal malunion, lateral subfibular impingement, tendon problems, sural nerve complications. There are many surgical or nonsurgical treatment modalities to manage those complications. However strategic initial surgical approach with gentle soft tissue handling accompanied by comprehensive understanding about numerous complications might be the best tool to achieve pain free and functional heel after treating calcaneal fractures.

The purpose of this study was two-fold : (1) to investigate the difference between the lifting capacities based on three different ergonomic approaches; a) the biomechanical, b) the physiological, and c) the phsychophysicalo approach, and the 1991 revised NIOSH Equation, and (2) to develop a comprehensive model for deter- mining maximum weight of lift.

Service engineering is a new discipline which aims at basically understanding of service and a concrete methodology using engineering approach for service design. In this paper is introduced the serviset graph [7] which is a comprehensive concept to represent service products, processes, and operation activities. The proposed concept is a degree of commonality index in a service product in order to deal with service mass customization using the input-output analysis in economic model.

In this work, we present a comprehensive and systematic approach for the derivation of the dc voltage generated by a magnetic multilayer undergoing ferromagnetic resonance, originally derived by Berger. Our alternative derivation applies especially in the limit of the spin diffusion length much longer than the carrier mean free path.

This paper provides a new theoretical rationale for public procurement for innovation (PPI), a unique policy encouraging public procurers to purchase innovative products. In contrast to existing studies that primarily emphasize the advantages of PPI, this paper takes a comprehensive approach, examining both the costs and risks associated with PPI, alongside its benefits. It finds a general condition under which PPI outperforms traditional public procurement. Under this condition, this paper demonstrates that PPI enhances social welfare by facilitating optimal risk-sharing between public procurers and the general economy. Additionally, it draws policy implications from a comparative analysis between the current PPI policy in Korea and an optimal PPI policy.

심리학계와 비슷하게 음악치료 분야 내의 세부적 치료이론 및 접근법들의 수는 날이 갈수록 빠르게 증가하고 있다. 이와 같은 다양한 접근법들의 개발은 특정 치료기법의 발전과 같은 긍정적 영향을 미치기도 하는 반면 지나친 세분화로 인해 임상적 또는 실용적인 측면에서 혼란을 야기시킬 수도 있다. 이와 같은 우려 하에 치료사들은 내담자를 위한 가장 효과적인 임상접근법은 무엇일지, 치료효과가 기대에 미치지 못할 때 전문성과 윤리성을 고려한 대처 방법은 어떻게 되는지, 보다 적합한 치료적 접근을 위해 다양한 치료이론과 접근법들을 융합 또는 통합 한 치료가 가능한지 등의 임상적 딜레마를 경험하기도 한다. 저자는 케네스 브루샤가 제안하는 "음악치료에서의 통합적 사고"(Integral Thinking in Music Therapy: ITMT)의 소개를 통해 위와 같은 임상적 딜레마들에 대한 하나의 방안을 제시하고자 한다. ITMT는 치료사들에게 내담자의 필요를 파악하고 접근함에 있어 다른 관점의 사고를 제안한다. ITMT는 다양한 치료 모델과 이론들을 수용하는 치료사의 사고 방법으로 각 모델들이 제 각기 다른 이유로 가치가 있음을 부각 시키며 어느 때에 어떠한 접근이 보다 적절한지 제시함으로써 내담자를 위한 최선의 선택을 위해 하나의 고정된 사고방식에서 벗어나 통합적인 사고를 하도록 유도한다. 이를 위해 본 논문은 ITMT의 기본 전제와 임상적 적용 및 실제 사례연구를 기반으로 ITMT의 적용 예시를 제시한다.
