The Web based multimedia programmes/courses are becoming widely available in recent years. Most of these courses focus on Behaviorist way of learning, which does not promote deep learning in any way. For Adults this approach further incapacitated, as it does not satisfy Andragogical needs. The search for Constructivist way of learning through the web applied to Indian conditions led to need for developing a curriculum development approach that would promote construction of knowledge through web based collaboration. This paper attempts to reengineer existing curriculum development processes and lays out a framework of‘Problem Based Online Learning (PBOL)’curriculum design. In this context, entire curriculum development life cycle is evolved and explained. This is a part of doctoral work (Ph.D), which is in progress and being undertaken by K.James Mathai, and guided of Dr.D.S.Karaulia.

Various information and communication technologies (ICT) and electronic government (e-Government) projects have been planted in hopes of economic and social growth in developing economies. These types of ventures usually involve working in societies with their own unique cultures in various aspects that often cause "custom ways" of planning, implementing, coordinating, and controlling in IT projects, thus playing a grand role in determining the success of IT projects. Due to a lack of understanding of local cultural factors and a deficiency of cultural risk evaluation models, however, many IT projects especially in the context of developing economies face failure. This study investigates the major cultural factors involved in IT projects and their effects on IT projects in developing economies. The framework is validated using the United Nations Development Programme's (UNDP) information and communication technology (ICT) and e-Government project cases of two countries in Central Asia, Uzbekistan and Kazakhstan. This study will help project managers develop management practices and strategies associated with the cultural factors they face during the various stages of their IT projects in their specific contexts.

1994년부터 발효된 UN 기후변화협약은 지구온난화의 방지를 위해서 각국의 자발적인 이산화탄소 배출 저감을 의무 사항으로 규정하고 있다. 우리 나라도 21세기에 들어서면 본격적으로 이산화탄소 배출 저감을 추진해야 할 것으로 예상되지만 에너지 절약의 측면에서나 대체에너지 개발의 측면에서 다른 나라들보다 상황이 크게 불리한 입장에 있다. 기후변화협약에 대비하는 한 대안으로 태양에너지를 이용할 필요성이 상당히 증대될 것이기 때문에 앞으로 태양에너지 관련 기술에 대한 수요는 현재보다 상당히 높아질 것으로 예상된다. 이런 점을 감안해서 본고에서는 먼저 기후변화협약의 내용들을 살펴보고 이에 대응하는 수단으로서 태양에너지 기술 개발의 전망을 포괄적으로 검토하였다. 특히 우리 나라에서는 고효율 태양전지의 대량 생산 기술과 태양열 이용 온수기 및 난방 시설의 효율 증진 기술 등이 유망하다고 전망되었다.

UN-REDD (United Nations programme on Reducing Emissions from Deforestation and forest Degradation) is currently being emerged as one of important mechanism to reduce carbon dioxide in relation to the deforestation. Although administrative boundary has already gained world-wide recognition as a typical method of monitoring unit in the process of GHG (Greenhouse Gas) reduction project, this approach did not provide a realistic evidence in the carbon sequestering monitoring in terms of UN-REDD; the meaningful comparison of land use patterns among watershed boundaries, interpretation for distribution trends of carbon density, calculation of opportunity cost, leakage management, etc. This research proposes a comparative evaluation framework in a more objective and quantitative way for carbon sequestering monitoring between administrative and watershed boundary approaches. Mt. Geumgang of North Korea was selected as a survey objective and an exhaustive and realistic comparison of carbon sequestration between the two approaches was conducted, based on change detection using TM satellite images. It was possible for drainage boundary approach to identify more detailed area-wide patterns of carbon distribution than traditional administrative one, such as estimations of state and trends, including historical trends, of land use / land cover and carbon density in the Mt. Geumgang. The distinctive changing trends in terms of carbon sequestration were specifically identified over the watershed boundary from 4.0% to 34.8% while less than 1% difference was observed in the administrative boundaries, which were resulting in almost 21-22%. It is anticipated that this research output could be used as a valuable reference to support more scientific and objective decision-making in introducing watershed boundary as carbon sequestering monitoring unit.

The resilience of a city confronted with a terrorist bomb attack is the background of the paper. The resilience strongly depends on vital infrastructure and the physical protection of people. The protection buildings provide in case of an external explosion is one of the important elements in safety assessment. Besides the aspect of protection, buildings facilitate and enable many functions, e.g., offices, data storage, -handling and -transfer, energy supply, banks, shopping malls etc. When a building is damaged, the loss of functions is directly related to the location, amount of damage and the damage level. At TNO Defence, Security and Safety methods are developed to quantify the resilience of city infrastructure systems (Weerheijm et al. 2007b). In this framework, the dynamic response, damage levels and residual bearing capacity of multi-storey RC buildings is studied. The current paper addresses the aspects of dynamic response and progressive collapse, as well as the proposed method to relate the structural damage to a volume-damage parameter, which can be linked to the loss of functionality. After a general introduction to the research programme and progressive collapse, the study of the dynamic response and damage due to blast loading for a single RC element is described. Shock tube experiments on plates are used as a reference to study the possibilities of engineering methods and an explicit finite element code to quantify the response and residual bearing capacity. Next the dynamic response and progressive collapse of a multi storey RC building is studied numerically, using a number of models. Conclusions are drawn on the ability to predict initial blast damage and progressive collapse. Finally the link between the structural damage of a building and its loss of functionality is described, which is essential input for the envisaged method to quantify the resilience of city infrastructure.

The soil behaviour can be represented by numerical modelling of element testing using diverse constitutive models. However, not all constitutive models allow the simulation of the stress-strain response at the critical state in granular soils with both contractive and dilative behaviour. Moreover, the accuracy of these models depends highly on the quality of the experimental data used for their calibration. This study addresses the modelling of the critical state behaviour of an alluvial natural soil from the Lower Tagus Valley (south of Portugal), known as TP-Lisbon sand, using the NorSand constitutive law. For this purpose, a series of numerical simulations of element testing was carried out using two algorithms performed in Visual Basic (VB) and Fast Lagrangian Analysis of Continua (FLAC). Moreover, this study presents the characterisation of of NorSand parameters from an accurate experimental programme based on triaxial and bender element testing. This experimental program allowed defining: (i) the critical state locus, (ii) the stress-dilatancy, and (iii) the soil elasticity of TP-Lisbon sand -all fundamental to calibrate the contractive and dilative behaviour of such alluvial soil. The results revealed a good agreement between experimental data and NorSand simulations using VB and FLAC. Therefore, this study showed that the quality of laboratory testing procedures and its good interpretation enables NorSand constitutive law to capture representatively the non-associated plastic strains, often expressed by the state parameter, allowing a representation of soil behaviour of alluvial soils within the critical state soil mechanics framework for different state parameters.

Purpose: Most emerging-market countries are concerned about the technology boom, which is accompanied by an increase in revenue from online sales and services. This finding has been demonstrated during the COVID-19 pandemic; however, is this tendency continuing in the new normal, and what factors are driving the increase in consumer decisions? The purpose of this research is to investigate how the decision to utilize online services will be affected in the new normal as well as propose a new research approach in this field. Research Design, Methodology and Approach: By following a deductive research method associated with positivist philosophy, a survey in South Vietnam with 426 respondents using a convenience sampling method was conducted. The reliability of the measurement scales was examined by using the SPSS program. The SmartPLS programme was utilised to assess the measurement and structural models as well as test hypotheses by using partial least squares structural equation modelling. Results: According to the research findings, decision-making has been impacted by social influences, perceived usefulness, perceived ease of use, perceived trust, perceived price, and perceived convenience. Conclusions: The research results also bring significant contributions not only in practice in providing management implications but also in theory. The research model has also demonstrated the feasibility of employing the stimuli-organism-response framework and combining the theory of perceived risk with the technology acceptance model via the explanation of decision-making.

There are little program and services that have been developed to address the health and health care needs of vulnerable women. The access for their timely and appropriate health care and health promotion services have been a increasing concern. The purpose of this study was to suggest health promotion program for vulnerable women with collaboration of women's NGOs. At the first part of this study, we reviewed a conceptual framework for identifying vulnerable population, and issues regarding health problems, unmet needs, policies and programs that have been developed to address their need. In second part, we focused on investigating the role, subjects and activities of women's NGOs and their capacity for health promotion program. The last part of this study proposed health promotion programme with integrating above two parts of study. In describing what type of health promotion program available in women's NCOs, eight major programs and services were summarized. 1. Direct health promotion program and collaborating program with other services. 2. Education and training for empowerment of vulnerable women 3. Organizing mutual support system such as self-help group 4. Community supports. Vulnerable women living at home may benefit from linkage to community services as much as women living in facility 5. Organizing collaboration system with program for economic support and job training, social rehabilitation 6. Trainer's training for practitioners in NGOs 7. Technical, informational support from professional groups 8. A national coordinating policies for vulnerable population should be established at the central level. National support for NGOs' health promotion program are needed hi solving unmet needs of vulnerable women.
