    This paper proposes a new formulation for the multi-objective optimal power flow (MOOPF) problem for meshed power networks considering distributed generation. An efficacious multi-objective fuzzy linear programming optimization (MFLP) algorithm is proposed to solve the aforementioned problem with and without considering the distributed generation (DG) effect. A variant combination of objectives is considered for simultaneous optimization, including power loss, voltage stability, and shunt capacitors MVAR reserve. Fuzzy membership functions for these objectives are designed with extreme targets, whereas the inequality constraints are treated as hard constraints. The multi-objective fuzzy optimal power flow (OPF) formulation was converted into a crisp OPF in a successive linear programming (SLP) framework and solved using an efficient interior point method (IPM). To test the efficacy of the proposed approach, simulations are performed on the IEEE 30-busand IEEE 118-bus test systems. The MFLP optimization is solved for several optimization cases. The obtained results are compared with those presented in the literature. A unique solution with a high satisfaction for the assigned targets is gained. Results demonstrate the effectiveness of the proposed MFLP technique in terms of solution optimality and rapid convergence. Moreover, the results indicate that using the optimal DG location with the MFLP algorithm provides the solution with the highest quality.

    OBJECTIVE: The learning styles of millennial students, also known as Generation 'Y', have been examined in the past to match the teaching style of an educator with the aim of improving behaviors, attitudes, and academic achievements. However, focus on Generation 'Y' healthcare undergraduates from a multi-cultural Asian society, is scarce and fragmented. Therefore, this research aims to identify the learning style preferences of Generation 'Y' undergraduates enrolled in varied healthcare programs at a Malaysian University.

    METHOD: A quantitative cross-sectional study design was adopted. Honey and Mumford's Learning Style Questionnaire was used to explore the learning styles.

    RESULTS: The reflector learning style was most preferred by the Malaysian healthcare undergraduates, and no significant difference was found between the learning styles of the clinical group and the semi-clinical group.

    CONCLUSIONS: Educators should engage Malaysian healthcare undergraduates in a non-threatening environment - Association between learning style and sociodemographic warrants further investigation.

  3. Respect redefined: focus group insights from Singapore

    This article re-examines the meaning of the concept of respect within the context of a fast modernizing Asian multicultural society-Singapore. Two key findings emerge. First, the meaning of respect both from the perspective of the aged and the middle-aged generation has shifted from obedience to courteous behavior. Second, in the majority of focus groups members concurred that the degree of respect accorded to elders has in general decreased. The focus group methodology was used in this research. Bearing in mind the limited sample size (88 participants) these findings alert us to the need for social scientists to monitor perceptual shifts in meaning of concepts critical in the sphere of interpersonal relationships. The findings throw light on the subjective views of intergenerational relations within the family as well as the community. As such, they would be valuable to counselors, social workers, and family therapists.
