A first-principle approach is used to analyze combined conductive/radiative heat transfer in a high porosity silica insulation materials (LI900) currently used by the Space Shuttle. Using the measured value of the refractive index (n, κ), solutions to the radiative transfer equation for fibrous insulation with a random packing geometry is used to generate macroscopic average radiative properties such as extinction coefficient, scattering albedo and phase function. Based on a non-gray application of the zonal method, transient thermal response of the insulation tile subjected to an external radiant flux is generated and compared with experimental data. The agreement is excellent. The computation is both efficient and accurate.Numerical results show that even with the presence of conduction and large extinction coefficient in some wavelength region, a large temperature drop ("temperature slip") occurs over a short distance near the heating surface. The inclusion of this effect is important for a correct interpretation of the heat transfer data.Copyright © 2003 JSME NOMENCLATURE a = absorption coefficient a = modified absorption coefficient A = constant in the Delta-Eddington scattering phase function C = specific heat f = forward scattering parameter g = anisotropic scattering factor g i g i (i,j = 1,2,…,N) = exchange factor between volume element i and j (g i g i ) t (i,j = 1,2,…,N) = total exchange factor between volume element i and j k = thermal conductivity k eff = effective thermal conductivity k inf = inferred thermal conductivity

With higher education, university graduates are important elements of the labor force in knowledge-based economies. With reference to the mental health and developmental problems in university students, there is a need to review university's role in nurturing holistic development of students. Based on the positive youth development approach, it is argued that promoting intrapersonal competencies is an important strategy to facilitate holistic development of young people in Hong Kong. In The Hong Kong Polytechnic University, a course entitled Tomorrow's Leader focusing on positive youth development constructs to promote student well-being will be offered on a compulsory basis starting from 2012/13 academic year under the new undergraduate curriculum structure. The proposed course was piloted in 2010/11 school year. Different evaluation strategies, including objective outcome evaluation, subjective outcome evaluation, process evaluation, and qualitative evaluation, are being carried out to evaluate the developed course. Preliminary evaluation findings based on the piloting experience in 2010/11 academic year are presented in this paper.
