As the recent economic downturn continues to undermine the profits of construction industry in Korea, it has become ever more pressing to improve productivity of the industry. Since construction site management manpower staffing plan has close bearing on the productivity of construction projects, it is essential to estimate and mobilize adequate number of resources as per conditions and characteristics of each construction site. However, there are no reference approaches in practice to provide baseline for site management manpower staffing plan or estimation of manpower requirement. Therefore, this study aims to examine factors affecting productivity that warrants first and foremost consideration in development of site management manpower staffing plan during the initial phase of building construction project by conducting survey on industry stakehoders with hands-on responsibilities in construction sites and analyzing their responses. Conclusions herein will provide basic inputs for subsequent studies on development of site management manpower staffing plan as per project characteristics.

This article examines the requirements of Article 37 of the ICDR International Arbitration Rules and issues that could arise if a party petitions a U.S. Federal Court to enforce an emergency arbitrator's Article 37 decision to grant pre-arbitration provisional relief. On May 1, 2006, ICDR introduced a new procedure for the granting of emergency arbitral relief under its ICDR Rules. The procedure enables a party to apply for emergency interim relief before the appointment of an arbitrator or tribunal to adjudicate the merits of the dispute. Instead, the application for emergency relief is considered by an emergency arbitrator appointed by the ICDR. In short, the ICDR has quickly appointed emergency arbitrator and resolved a challenge to an appointment within 36 hours. In addition, the emergency decisions have been issued within just a couple of weeks. In particular, we looked at what would happen after Article 37 emergency relief is granted. Based on my examination of U.S. cases on the enforceability of interim awards and orders, We conclude that U.S. courts would enforce Article 37 interim measures, whether they are characterized by the emergency arbitrator as an interim order or award. Where the situation warrants, arbitration executives should embrace and use emergency relief procedure of ICDR Rules.

Cutting procedures where qualities are determined by various demand factors largely influences shipbuilding productivity. Particularly, defects in cutting shapes and cutting surface results in delay for post shipbuilding stages such as in welding and assemblage lines which could become factors for reduced economic viability of the project. Existing cutting procedures utilize fossil fuels such as propane or ethylene as the main fuel component and these methods applied particularly to ship plate cutting gives relatively slow cutting speed and generates large quantities of harmful and sometimes poisonous polluting fumes of which warrants an urgent need to look for alternative cutting methods. Recent introduction of hydrox gas generated by electrically dissociating water into hydrogen and oxygen components to be utilize as an alternative cutting fuel has resulted not just in visible improvement on cutting quality and speed over the existing methods but it has also been welcomed as an environmentally friendly clean fuel source. This paper has been prepared to serve as the basis for accommodating this environmentally friendly hydrox gas cutting method into actual working environment by observing and recording hydrox gas cutting thermal characteristics.

Some microRNAs (miRNAs) have been shown to act as oncogenes or tumor suppressor genes in human melanomas. miR-328 is upregulated in blood cells of melanoma patients compared to in healthy controls. This suggests a role for miR-328 in melanoma that warrants investigation. In this study, we demonstrated miR-328 levels to be dramatically decreased in human melanoma cell lines. Moreover, forced expression of miR-328 inhibited proliferation and induced G1-phase arrest of the SK-MEL-1 melanoma cell line. We identified TGFB2 as a direct target gene for miR-328 using a fluorescent reporter assay and western blotting. Levels of TGFB2 were dramatically increased in human melanoma cell lines and were inversely correlated with the miR-328 expression level. Our findings provide new insights into the mechanisms of human melanoma development, indicating that miR-328 has therapeutic potential for this disease.

Environmental awareness and its relation to the development of economy has garnered increased attention in recent years. Researchers, over the years, have argued that sustainable development warrants for minimizing environmental degradation since one depends on the other. This study analyzes the relationship between environmental degradation (carbon emission taken as proxy for degradation), economic growth, total energy consumption and industrial production index growth in Bangladesh from year 1998 to 2013. This study uses Vector Autoregression (VAR) Model and variance decomposition of VAR to analyze the effect of these variables on carbon emission and vice-versa. The findings of VAR model suggest that industrial production and GDP per capita has significant relationship with carbon emission. Further analysis through variance decomposition shows carbon emission has consistent impact on industrial production over time, whereas, industrial production has high impact on emission in the short run which fades in the long run which is consistent with Environmental Kuznets Curve (EKC) hypothesis. Carbon emission rising along with GDP per capita and at the same time having low impact in the long run on industrial index indicates there may be other sources of pollution introduced with the rise in income of the economy over time.

Religious intolerance has become a common feature of many countries in recent times. Studies have revealed a worldwide increase in government regulations and social hostilities against religious beliefs and practices. The stifling impact of both government and society on the market for religion, warrants closer scrutiny. This study examines the relationship between government regulations and social hostilities towards religious beliefs and practices, for the period of 2001-2011 for a sample of 45 European countries. The Generalized Method of Moments dynamic panel estimation technique is employed to analyze the micro panel dataset of 45 European countries, to establish the possible relationships that may exist between these variables. The theoretical framework for this study is based on the Religious Economies Theory and the Supply Side Theory of Religion. The results of this study show evidence of the positive relationship between government regulations and social hostility. Interestingly, the study also revealed that the impact of social hostility on the level of government restrictions is smaller in magnitude compared to the reverse impact of government restrictions on social hostilities, indicating the dangerous role played by governments in inciting social hostilities, when they regulate or restrict religious beliefs and practices.

Background: Because of the gender disparity in the incidence of thyroid cancer, this study aimed to determine the association between reproductive factors and thyroid cancer. Methods: A total of 10,767 eligible women from the Khon Kaen Cohort, recruited and interviewed between 1990 and 2001, were followed up until 2011. The data were linked to the Khon Kaen Population-Based Cancer Registry to detect thyroid cancer cases. Results: There was 17 thyroid cancer cases detected, an incidence of 11.2 per 100,000 person-years, of which 70.6 % were papillary tumors. The incidence was apparently greater among those with an early age of menarche, nulligravida women, and oral contraceptive users. Conlusions: There was a trend for thyroid cancer to develop in relation to longer estrogen exposure. This evidence is inconclusive but warrants further investigation.

Objectives : This study aimed to investigate both cancer patients' willingness to participate (WTP) in clinical trials and its associated factors. Methods : We searched MEDLINE (PubMed) for studies that had investigated cancer patients' WTP in clinical trials. Search terms included 'willingness to participate', 'cancer' and 'trial'. Studies published within the last five years up to July 26, 2016 were potentially eligible. Results : Of 44 initial hits, 14 studies (12 quantitative and 2 qualitative) were included. Two out of the 14 studies investigated WTP in an acupuncture trial. Study designs, such as WTP measurement methods, investigation settings, and type of cancer, varied. The proportion of participants with a WTP was widely distributed between the studies (median 48.6 %, range 11.1 % to 88.3 %). Factors associated with WTP included various socio-demographic factors, clinical factors, participants' knowledge/attitudes toward clinical trials, travel distance, information from physicians, and trust toward physicians. Conclusion : WTP and its associated factors were variable across the reviewed studies, which might be due to different research methods and contexts. Whether or not common factors associated with cancer patients' WTP in clinical trials exist remains unclear and thus warrants further research.

We investigated the antifungal activities of an endophytic fungus identified as Acaromyces ingoldii, found on a loblolly (Pinus taeda L.) pine bolt in Louisiana during routine laboratory microbial isolations. The specific objectives were to determine the inhibitory properties of A. ingoldii secondary metabolites (crude extract) on the mycelial growth of a brown-rot fungus Gloeophyllum trabeum and a white-rot fungus Trametes versicolor, and to determine the effective concentration of A. ingoldii crude preparation against the two decay fungi in vitro. Results show the crude preparation of A. ingoldii from liquid culture possesses significant mycelial growth inhibitory properties that are concentration dependent against the brownrot and white-rot fungi evaluated. An increase in the concentration of A. ingoldii secondary metabolites significantly decreased the mycelial growth of both wood decay fungi. G. trabeum was more sensitive to the inhibitory effect of the secondary metabolites than T. versicolor. Identification of specific A. ingoldii secondary metabolites, and analysis of their efficacy/specificity warrants further study. Findings from this work may provide the first indication of useful roles for Acaromyces species in a forest environment, and perhaps a future potential in the development of biocontrol-based wood preservation systems.

The conventional osseointegration protocol calls for waiting up to 12 months for ossification of an extraction socket to heal before placing an endosseous implant. In this study, the possibility of placing a pure titanium implant directly into an extraction socket immediately after extraction was investigated. And the marginal bone loss of immediate nonsubmerged and submerged endosseous dental implants placed into extraction sockets was also compared. Pure titanium Nobelpharma Branemark implants and solid screw type ITI implants were placed into premolar extraction sockets of two adult dogs and allowed to heal for a period of 3 months, followed by functional loading of the implant. Radiographic examination was performed before implantation, immediately after implantation and 3, 6, 9, 12 months after implantation. The results obtained were as follows : 1. Immediately placed nonsubmerged ITI implants and submerged Branemark implants showed favorable radiographic osseointegration status and there were minimum marginal bone loss. 2. There were no significant differences in radiographic finding of osseointegration between conventional and immediate implantation. 3. Gingival tissue around implants showed more inflammatory signs than that of adjacent natural teeth. This study suggest that pure titanium Branemark implants and submerged ITI implants have the potential to integrate when placed immediatly after extraction of the teeth and warrants further investigation.
