Impact of solar shading geometry on building energy use in hot humid climates with special reference to Malaysia
External solar shading devices can substantially reduce the cooling load of buildings and large energy savings can be achieved. Hence, intercepting the radiant heat wave before penetrating to the internal environment through envelope openings is the main criterion in designing solar shading. In hot and humid climate, one draw back of using shading devices is the risk to reduce daylight level thus increases in use of artificial lighting. Therefore it is important to understand the magnitude of energy consumption for cooling and lighting when shading devices are adapted in order to analyze optimum shading as energy conservation option in high-rise office buildings. In other words, little is known about the relationship between energy use and external horizontal shading device geometry. In an attempt to elucidate these complex relationships, a simple experiment of an office room is carried out using dynamic computer simulation program eQUEST- 3 (DOE 2.2). The study indicated depth of the external horizontal overhang can be manipulated to obtain an optimum energy use in high-rise buildings. The results showed that correlation between overhang depth and energy is an important aspect compared to correlation between overhang depth with building cooling loads and daylight level, especially in tropical climate conditions

Rumah merupakan bangunan yang dibangun dengan tujuan untuk dijadikan tempat tinggal oleh manusia. Proses pembuatan rumah tak lepas dari penyesuaian antara kebiasaan dan kegiatan dari manusia yang akan menghuninya dari waktu ke waktu. Di Indonesia, rumah - rumah adat yang diturunkan oleh nenek moyang dapat dikatakan sebagai arsitektur nusantara. Rumah-rumah tersebut memiliki ciri khas tersendiri sesuai dengan tata letak geografisnya, sumber daya, adat, kepercayaan, kebiasaan dan budaya masyarakatnya. Masyarakat Dayak memiliki sistem tersendiri dalam mengorganisir kelompok suku mereka dalam hunian mereka. Suku Dayak pada umumnya menganut prinsip kekerabatan ambilineal. Prinsip kekerabatan ini mengharuskan seseorang untuk tinggal bersama dengan kerabat - kerabatnya dalam sebuah rumah. Studi ini difokuskan untuk mengidentifikasi pembagian ruang pada rumah Lamin, yang mana pembagian ruang ini sangat dipengaruhi oleh sistem adat yang berlaku. Tujuan artikel ini adalah untuk mengetahui Tipologi ruang dalam rumah tradisional Lamin. Hasil studi tentang tipologi ruang dalam rumah Lamin dapat dijadikan sebagai esensi pedoman bentuk Arsitektur rumah Lamin, yang akan memberikan kontribusi terhadap keilmuan arsitektur nusantara

The dynamics of personal ethics and ethical climate in public relations practitioners’ decision making
This study examines the contemporary pragmatic public relations ethics that focuses on decision making to relate public relations practitioners’ ethics with their organizational ethics using Grunig and Hunt (1984) excellence theory. The aim of this study is to identify the association and the strength of the association between public relations practitioners’ ethical evaluation and ethical climate of the organization in decision-making process. This study used a structured questionnaire to measure the three different parameters in ethical evaluation (reasoning, consideration, and judgment) and the ethical climate of the organization simultaneously. The association between them is later identified from the Pearson correlation test. Respondents selected were 100 people who actively practicing public relations around Kota Kinabalu. The study revealed a positive, weak correlation as the indication that the score of ethical evaluation can but not always be used to predict the score of ethical climate. In ethically challenging decision making, one’s personal ethics is barely associated with organization’s ethical climate. Furthermore, the association shows that public relations practitioners are predominantly evaluate the situation and make ethical decision in ethical organization, though dilemmas are tempting and dragging towards unethical decision. In such inconsistency between practitioners and their organization, it is problematic because the interpersonal and organizational aspects in ethical decision making can help the organization to pursue an excellent, ethical public relations practice when addressed strategically
CPB1 of Aedes aegypti Interacts with DENV2 E Protein and Regulates Intracellular Viral Accumulation and Release from Midgut Cells
Aedes aegypti is a principal vector responsible for the transmission of dengue viruses (DENV). To date, vector control remains the key option for dengue disease management. To develop new vector control strategies, a more comprehensive understanding of the biological interactions between DENV and Ae. aegypti is required. In this study, a cDNA library derived from the midgut of female adult Ae. aegypti was used in yeast two-hybrid (Y2H) screenings against DENV2 envelope (E) protein. Among the many interacting proteins identified, carboxypeptidase B1 (CPB1) was selected, and its biological interaction with E protein in Ae. aegypti primary midgut cells was further validated. Our double immunofluorescent assay showed that CPB1-E interaction occurred in the endoplasmic reticulum (ER) of the Ae. aegypti primary midgut cells. Overexpression of CPB1 in mosquito cells resulted in intracellular DENV2 genomic RNA or virus particle accumulation, with a lower amount of virus release. Therefore, we postulated that in Ae. aegypti midgut cells, CPB1 binds to the E protein deposited on the ER intraluminal membranes and inhibits DENV2 RNA encapsulation, thus inhibiting budding from the ER, and may interfere with immature virus transportation to the trans-Golgi network
Total quality management in the health-care context: integrating the literature and directing future research
Background: Synergistic integration of predictors and elements that determine the success of total quality management (TQM) implementations in hospitals has been the bane of theoretical development in the TQM research area. Thus, this paper aims to offer a systematic literature review to provide a foundation on which research on TQM can be built and to identify the predictors of successful TQM in the health-care context. Materials and methods: A systematic literature survey was adopted in this paper, involving the review of 25 relevant researched articles found in the databases Science Direct, EBSCO, MEDLINE, CINAHL and PubMed. Result: The systematic literature survey reveals five variables to be core predictors of TQM, signifying how important these variables are in the successful implementation of TQM in the health-care context. Also, it is revealed that the identified core predictors have positive effects on an improved health-care system. However, the systematic survey of the literature reveals a dearth of studies on TQM in the health-care context. Conclusion: As TQM has become an important management approach for advancing effectiveness in the health-care sector, this kind of research is of value to researchers and managers. Stakeholders in the health sectors should introduce and implement TQM in hospitals and clinics. Nevertheless, this study has limitations, including that the databases and search engines adopted for the literature search are not exhaustive
