The influence of the external temperature on a cooling box thermoelectric system
Yuri R. Fischer, Italo S. Silva, José C. C. Dutra
Abstract In the present paper, a thermoelectric cooling system modelling of a box was developed and the influence of the external temperature on this system was analyzed. The modelling shows that high external temperatures limit the thermoelectric cooling performance of the system. It was observed also that the external temperature limit the value of heat that can be removed by the thermoelectric system for each internal temperature set point of the cooling box. Substitute the thermoelectric cooling module (TEC) is an option to improve the cooling performance, however is important to observe that the external temperature can affect this improvement.

Testing the air delay variability
Daniel Alberto Pamplona, Claudio Jorge Pinto Alves
Abstract Delay is a key point in the air transportation activity. It is considered a performance metric and a multidimensional issue. Delay is directly responsible for increased costs to airlines and passengers, airline loss of demand and profitability, and indirectly impact the economy of a country. Although the air traffic flow management (ATFM) literature indicates that most congestion problems are fixed on the day of operations tactically there is a lack in the literature that verifies the difference between delay averages. The objective of the present study is to investigate the existence of variability among air delay. We examined the yearly, monthly, daily, hourly and weekly air delay median differences using statistical tests. We conducted three statistical tests in the present study. Initially, we used the Kruskal-Wallis equality of populations rank test. We adopt it to establish if there are statistically significant differences between two or more delay groups. Since it is an omnibus statistic test, to determine which groups are different, we conducted two post hoc test: the Dunn´s Multiple Comparison test and The Conover-Iman Pairwise test. Results showed that the yearly and weekly intragroup median delay presented singularity, indicating that each time is unique. For the monthly, daily, and hourly median delay displayed intragroup similarities, as the demand intensity can be translated into the level of delay faced by the system. The present study contributes to the air delay literature showing that each operational period displays a characteristic behavior. For this reason, all the planned solutions to decrease air delay must be adapted according to the presented situation in the day of operation. Our study emphasizes the importance of local, determined and adjustable measures with a huge emphasis on the concrete problem to decrease the air delay.

Knowledge and Attitude of Nigerian Undergraduates toward Voluntary HIV Counseling and Testing: A Case Study
J. Kio, C. Agbede, K. Kosoko, T. Leslie
Abstract HIV/AIDS is a major health concern in Africa with half of new infections occurring in young people. This study aimed at assessing knowledge and attitude of Nigerian undergraduate towards voluntary HIV counseling and testing (VHCT) with the null hypothesis that knowledge and personal characteristics do not influence attitude. Descriptive study design was used. Information were collected from 174 undergraduates (from selected University) using structured questionnaire (78% reliability). All analyses were at p≤0.05. Result showed that most of the respondents (53%) visited the health counselor for VHCT only once particularly to fulfill admission procedure. Moderate level of knowledge of HIV/AIDS was observed among the respondents and poor attitudes toward VHCT. Factors responsible for the poor attitudes includes: peer influence and assumed public stigmatization. Positive and significant relationship was found between knowledge level and attitudes towards VHCT. The study concludes by emphasizing that HIV awareness drive by Nigerian institutions should be more intentional about increasing the knowledge of the youth especially as regards risky sexual behaviour and need for routine testing. Furthermore, Institutional policy framework combining parental and institutional guardians and counseling in combating HIV/AIDS in Nigeria should be explored.

Influence of Silvicultural Techniques on the Occurrence of Compression Wood and Consequences on Wood Quality
Vinícius Rosa Schweitzer, Jorge Luis Monteiro de Matos, Martha Andreia Brand, José Guilherme Prata
Abstract Wood quality is affected by several factors intrinsic to the tree and its growth and external and genetic factors that contribute to unwanted changes that compromise its use in the industry. Pinus taeda is the most widely planted species in southern Brazil, with a planted area of over 1.5 million hectares, and is of fundamental importance to the construction, furniture manufacturing and pulp and paper industries. The objective of this study was to evaluate the influence that the management techniques and the origin of the seeds used in seedling production have on the occurrence of compression wood and its consequences on wood quality. We analyzed 18 year old Pinus taeda trees from two different origins, which received silvicultural and non - silvicultural treatments. The trees were evaluated for their chemical, physical and mechanical properties. The evaluation of the physical properties of the samples was performed by characterizing the basic specific mass, the chemical properties used in the characterization were, inorganic material content, ethanol / toluene extractives, sodium hydroxide (NaOH) and total extractives, insoluble lignin contente and holocellulose, in turn the mechanical properties were measured through the modulus of rupture and elasticity of the samples to the tests of static flexion and parallel compression to the fibers. The main results of this study were that the presence of compression wood was found only in trees from South Africa and were submitted to management techniques, that the application of management techniques can not be considered as the only causative fator compression wood, which the occurrence of compression wood significantly affected several properties of Pinus taeda wood, among them the basic specific mass, the indices of the sodium hydroxide extractives, the ash content, the insoluble lignin and the holocellulose as well as reduced the modulus of elasticity of the wood in the static bending test. The Brazilian plantations of Pinus taeda are mostly formed by the South Africa origin, and it was only observed in this origin the occurrence of compression wood, which may cause significant losses to the Brazilian Pinus production chain.

Gunariantoa. Mulyonob
Abstract The objectives of this research are: 1) to understand leading sectors that positively contribute to economic growth; and 2) to comprehend One Tambon One Product (OTOP) implementation strategies in Malang Raya. Research object is Micro, Small & Medium Enterprises in Malang Raya. Data analysis is done with various techniques such as long list of leading commodities, Analytical Hierarchy Process (comprising activities such as building hierarchy, conducting survey and analyzing survey result), and Focus Group Discussion. Result of research provides few findings. Leading commodities of Malang City are derived from three kinds of trading system, namely, traditional trade (for vegetables, fishes and its kinds), large-scale trade, and mixed trade. Malang Regency's leading commodities produced mostly by industries, such as food industry, wood industry, metal industry, and plait/pottery/ceramic industry. Batu City’s leading commodities are emanated from wholesale market, star and jasmine hotels, natural and artificial tourism, food and beverage, and wet and mixed markets. The implementation of OTOP Program in Malang Raya, however, is not fully supported by local government in various levels. Local government, therefore, is suggested to play significant roles regarding to this matter, such as by identifying potential products that can be administered in OTOP Program, giving business advices to producers, maintaining packaging quality, and controlling product design to make sure that products are attractive in the market. Local government can also do some supporting activities such as facilitating marketing channel, managing market chain, and providing access to internet. Supporting organizations must be made available, such as supporting agent for business development or that for technical assistance, and also coordinator forum across institutions. Those supporting organizations may later be helpful in implementing many strategies for MSMEs development, and the suggested strategy in this context is product differentiation.

Choo-Peng Tan, Choo-Kim Tan, Siong-Hoe Lau, Shaun Ng Wes
Abstract Student’s performance and achievement is always a concern. Teaching and learning process with not only blended learning but with learning agents too is found benefited. In Malaysia, it was found that incorporating conversation-based agents in teaching and learning is very rarely. Thus, this project aims to propose a framework to develop a conversation-based agent that assists students’ learning in blended learning and to examine the effects of incorporating conversation-based agent on students’ achievement in mathematics. Results from phase I showed that all students had never used the conversation-based learning agents in their learning and they are looking forward to use the conversation-based learning agents which they believe that the agents will make the learning fun and interesting. It is hoped that the framework that will be designed and developed in this study is significant to the instructional designers and educators in helping students to reduce difficulties and anxiety level in mathematics and thus improve performance in mathematics.

Rationalization of Action Process on Fishermen Society
Awaluddin Hamzah, i Muhaimin Hamzah, Hartina Batoa, Abdul Gafaruddin, Muh. Aswar Limi, Syamsul Alam Fiyka, La Ode Kasno Arif
Abstract The high social differentiation in industrial society is strongly influenced by machine, capital, and expertise in the ongoing work process, which in turn classifies industrial workers based on mastery of the elements of production. This study can provide recommendations for a model of empowerment of fishing communities based on patronage institutions that are experiencing dynamics. The location of this research study was chosen purposively based on the consideration of access to enter the area, personal relationships between researcher and prospective informants (respondents) had been well established; the majority of the people in this area worked as fishermen. The very prominent institutions were patron-client relations system. Rational actions (consideration of effectiveness and efficiency) of fishermen were seen in the consideration to create innovation in terms of catch technology. This was performed to increase the production and income of fishermen. However, rationalization did not develop in terms of reinvestment, even though the Punggawa (Indonesian terms - especially Bugis society - of capital owners) was actually able to do it. In addition to the availability of fishing support institutions, fishermen could also concentrate fully on fishing activities until at the time fish brought to land. The growing rationalization of actions has not been able to move the economy of the fishing community as a whole. This is also one of the factors that causes patron-client institutions to continue to exist (survive) in the midst of society.
