  • Increase in energy consumption in building is a big concern world over. In Nepal, energy crisis is a big issue but energy demand in buildings is barely even thought about. In the southern part of Nepal, where the weather is mostly hot during the year, cooling in buildings is very important. This is an initial study regarding building design strategies which focuses on cooling energy consumption in the building. It can be seen from the study that simple passive strategies can be applied in building design which can support in decreasing cooling load. Different passive cooling strategies like orientation, building size, thermal mass, window design and two direct cooling strategies have been investigated in this study. Direct cooling strategies like shading and natural cooling helps in passive cooling. Different desing strategies have different impact on the cooling energy requirement and the study shows that thermo physical property of building materials has the maximum effect on the energy consumption of the building. Each design strategy creates and average of 20% decrease in energy consumption, whereas the thermal conductivity can have as much as 10 times more effect on the energy consumption than other design strategies.

  • The purpose of this paper is to examine some of the theories concerning socioaffective strategies, to analyze the dialogues of the students negotiating for meaning of a reading material and to suggest some implications of socioaffective strategies for teaching reading. The examination of the theories - the interaction hypothesis and the sociocultural theory - suggest that the use of socioaffective strategies facilitates more effective understanding of information that is to be found. distributed, and taken in among the participants. The discourse analyses of the students' interaction in a Korean college English reading class show ample evidence of the use of socioaffective strategies that helped them understand the meaning of a text. However, the analyses show that the strategies are mostly used to ask questions concerning the meaning of clauses. Only few analytical questions are raised for some structural and pragmatical features in the text which are crucial to the understanding of its meaning. Imbalance also exists in the types of the questions used by the participants. The analyses indicate that, instead of negotiating more interactively, the students tend to rely upon a more advanced student when they face difficult English sentences. Therefore as a conclusion this paper emphasizes the importance of teaching socioaffective strategies to help students to help themselves to become more cooperative, independent and analytical in reading English texts.

  • Purpose - The purpose of this paper is to analyze and illustrate Amazon's business strategies and its success in terms of its distribution strategy and business practices. Research design, data, and methodology - This is an analytical case study that examines Amazon's business strategies to demonstrate the importance of technologies to the success and sustainability of its organization. Results - The analysis indicates that the business strategies, including technology, distribution infrastructure, and customer service, are the most vital factor for the success and rise of Amazon, and these strategies have separated Amazon from its competitors in both e-tail and brick and mortar retail industries. Conclusions - Given Amazon's continued growth that came with its constant strive for delivery and cost efficiency, technology innovation, and customer satisfaction, it was inevitable that Amazon would eventually venture into different types of businesses. The previous and current Amazon's business strategies demonstrate that Amazon will continue to focus on developing and implementing new and creative strategies to separate itself from the rest of the retail and e-businesses. Furthermore, retail businesses in the most high-tech countries in the world, including Japan, Korea, and Russia, may have to adopt business strategies that are similar to those of Amazon to maintain their competitiveness.

  • The purposes of this study were to test the differences in communicative competence and conflict-resolving strategies between both popular and rejected children, and to thereby verify the discriminance of communicative competence and conflict-resolving strategies for both types of children. 52 popular children and 41 rejected children from among a pool of 202 6th grade elementary students were selected, and the data were analyzed by means of independent sample t-test and discriminant analysis. The research findings are as follows : First, listen up (sub-factors of perceiving), self-presentation, planning, and coding revealed statistically significant differences between the popular and the rejected children. Second, only negotiation and cooperation strategies revealed any statistically significant differences between the popular and the rejected children, while other sub-factors of conflict-resolving strategies indicated broad indifference between them. Third, it was only the factor of planning among 5 factors of communicative competence and 4 factors within conflict-resolving strategies which indicated that it was the most discriminant predictor between the popular and the rejected children. These results suggest that a comprehensive program is needed to improve the communicative competence and conflict-resolving strategies of rejected children.

  • Objectives: This review is to suggest strategies to reduce risk factors of non-communicable diseases (NCD) in South Korea. Methods: Prior research findings on the burden of NCD and associated risk factors and the effectiveness of intervention programs were reviewed. Strategies regarding the control of NCD risk factors were conceived. Results: The author presented research findings from the Global Burden of Disease study on the burden of non-communicable disease (NCD) and associated risk factors in South Korea. Strengths and limitations of population and high-risk strategies for preventing NCDs were introduced. The author also reviewed the evidence on the effectiveness of multiple cardiovascular risk factor interventions and community-based intervention programs on cardiovascular diseases conducted in industrialized countries. Finally, strategies to reduce NCD risk factors in South Korea were suggested. Conclusions: The evidence-based interventions and the importance of population strategies in NCD prevention were highlighted. The author indicated that strategies employed by unhealthy commodity industries to undermine effective public health policies and programs should be actively monitored. It has been suggested that effective high-risk strategies with ecological models to address social risks rather than medical risks among disadvantaged population should be further developed in South Korea.

  • This paper presents an estimation method of container handling capacity and selection of resource allocation strategies of container terminals using the computer simulation models. Simulation models are developed to model container terminal consisting of 4 berths considering the berth allocation strategies, crane allocation strategies and the total number of container cranes using Arena simulation package. The proposed models do not consider the yard operations and gate operations. All the input parameters for the models are estimated on the basis of the existing container terminal operation data and the planning data for the automated container terminal planned by Korean government. Four berth allocation strategies and three crane allocation strategies are considered. The total number of container cranes considered ranges from 12 to 15. Non-terminating simulation techniques are utilized for the performance comparison among alternatives. The performance measures such as average ship turnaround time, average ship waiting time, average ship service time, the number of containers handled per year, and the number of ships processed per year are used. The result shows that the berth allocation strategy minimizing the sum of the number of ships waiting, the number of busy container cranes and number of ships handled performs better than any other berth allocation strategies. In addition, the crane allocation strategy allocating up to 5 container cranes per berth performs better than any other crane allocation strategies. Finally there are no significant performance differences among the alternatives consisting of different total number of container cranes allocated.

  • This study investigated vocabulary learning strategies used by EFL middle school learners in Korea and examined the relationship between the middle school learners' vocabulary learning strategy (VLS) use and their vocabulary proficiency level. One hundred and forty-one students in a public middle school participated in the study and the data for this study were collected from a vocabulary learning strategy questionnaire and a vocabulary proficiency test. Based on the result of the vocabulary proficiency test, the participants were divided into three proficiency groups: high-, mid- and low- level proficiency groups. The overall findings of the study revealed that the participants used cognitive strategies most frequently and social strategies least frequently. The most frequently used individual strategies were 'using a bilingual dictionary,' 'studying the sound of a word' and 'practicing words through verbal repetition.' The least frequently used ones were 'interacting with native speakers' and 'studying or practicing the meaning of a word in a group.' The research results also showed that the vocabulary proficiency level has a significant influence on the vocabulary strategy use. The more proficient learners used vocabulary learning strategies more actively. More specifically, the high proficiency level group used metacognitive strategies the most. The middle and low proficiency groups used cognitive strategies the most. It is suggested that language teachers should facilitate the vocabulary learning process by helping learners develop appropriate strategies.

  • The purpose of this study was to gain an understanding about urban housewives' stress in family financial management, their coping strategies, and their sense of economic well-being, which will eventually provide some baseline data for policy development. The findings of this study are summarized in the following. First, the mean score of the level of financial management-related stress among urban housewives was 2.61 when the maximum level was set at 5. In order to overcome the stress from financial management, housewives utilized various strategies, such as purchasing management, financial planning, financial information gathering, getting a loan, and delaying payments. The average level of economic well-being among urban housewives was 2.82 when the maximum level was 5. Second, among socio-demographic factors, the family's monthly income and the husband's job satisfaction were the two most significant factors that affected the level of financial management stress among housewives. Third, there was a difference in employing coping strategies according to the level of stress. The group with a higher level of financial stress employed more coping strategies than the group with, a lower level of stress. Fourth, there were differences in the level of economic well-being, depending on the types of coping strategies employed. Fifth, the results from regression analyses, which were conducted to determine the relative explanatory power of different independent variable groups including subjective factors, financial management stress, and coping strategies, showed that socio-demographic and objective economic factors significantly affected economic well-being.
