  • Purpose: This review aimed to integrate the results of studies related to presenteeism in clinical nurses and to suggest directions for future research. Methods: The search for relevant studies was conducted using six data bases according to predetermined index terms, "$nurs^*$" and "presenteeism." Thirteen studies that met the inclusion criteria were selected and analyzed. Results: This review found that the conceptual use and scope of presenteeism were not consistent among the studies. Most studies investigated the nurses' health-related variables as the most important factors and reported their positive association with presenteeism. Presenteeism was also found to be associated with job stress, job satisfaction, social support, and organizational culture and had a negative impact on nursing outcomes such as patient safety. Conclusion: The research on presenteeism can be used as a way to explain outcomes in the field of nursing where direct measurement of productivity is difficult. Presenteeism is a multidimensional problem, and a theoretical foundation is needed to explain the presenteeism of clinical nurses.

  • The purpose of present study was to examine the efficacy of PAB (para-amino benzamidine) affinity column chromatography, pasteurization ($60^{\circ}C$ heat treatment for 10 h), and lyophilization steps, employed in the manufacture of urokinase from human urine, in the removal and/or inactivation of urine-born viruses. Bovine herpes virus (BHV) and Murine encephalomyocarditis virus (EMCV) were selected for this study. Samples from the relevant stages of the production process were spiked with the viruses and the amount of virus in each fraction was quantified by 50% tissue culture infectious dose ($TCID_{50}$). BHV and EMCV were effectively partitioned from urokinase during PAB chromatography with the log reduction factors of 6.71 and 5.27, respectively. Pasteurization was a robust and effective step in inactivating BHV and EMCV, of which titers were reduced from initial titers of $8.65\;log_{10}\;TCID_{50}$ and $7.81\;log_{10}\;TCID_{50}$, respectively, to undetectable levels within 1 hour of treatment. The log reduction factors achieved during lyophilization were 2.06 for BHV and 4.54 for EMCV. These results indicate that the production process for urokinase has sufficient virus reducing capacity to achieve a high margin of virus safety.

  • The lacks of local workforce supply become a problematic in Malaysian construction industry. Meanwhile, HRP is important during workforce supply to help organizations in order to appoint the right people in the right job. This paper reports on the use of factors influencing HRP towards local workforce supply in the construction industry in general, and Malaysian construction in particular. Semi structured interviews were conducted to 10 interviewees from the government and non-government organizations to investigate current issues of local workforce and the practices of HRP in the construction organization. The analysis methods were based on descriptions of previous tested research. The findings reveal that the lack of local workforce is due to low wages system, safety issues, educational changes, low status and unsecured work, environment in construction industry, developments and technologies changes in Malaysia. The internal factors of HRP were practiced among construction organization are organization strategy, organizational culture, organization changes, leadership and experience, nature of work and empowerment of labor. Meanwhile, the external factors are technology changes, economic changes, legislation and demographic changes. The paper provides valuable information on the practices of factors influencing HRP for local workforce supply in Malaysian construction industry.

  • Dioxins, especially 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin (TCDD or dioxin), are ubiquitous environmental contaminants. TCDD is known that it has toxic effects in animals and humans, including chloracne, immune, reproductive and developmental toxicities, carcinogenicity, wasting syndrome and death. TCDD induces a broad spectrum of biological responses, including disruption of normal hormone signaling pathways, reproductive and developmental defects, immunotoxicity, liver damage, wasting syndrome and cancer. Many researches showed that TCDD induces gene expression of transcriptional factors related cell proliferation, signal transduction, immune system and cell cycle arrest at molecular and cellular levels. These toxic actions of TCDD are usually mediated with AhR (receptor, resulted from cell culture, animal and clinical studies). cDNA microarray can be used as a highly sensitive and informative marker for toxicity. Additionally, microarray analysis of dioxin-toxicity is able to provide an opportunity for the development of candidate bridging biomarkers of dioxin-toxicity. Through microarray technology, it is possible to understand the therapeutic effects of agonists within the context of toxic effects, classify new chemicals as to their complete effects on biological systems, and identify environmental factors that may influence safety.

  • Land price can be affected by convenience or psychological repulsion like PIMFY (Please In My Front Yard) or NIMBY (Not In My Back Yard) for various facilities. Services related to public establishment, welfare, medical attention, and amenities in rural areas are comparatively poorer than those in urban areas. The purpose of this study is to estimate the implications of the accessibility to community facilities in rural areas for land prices using a hedonic price model. The accessibility to facilities is estimated by real road distances and the land prices are applied for four types of land usages: field, rice paddy, building lots, and village halls. Community facilities are classified from public and community services view: education, safety, culture, transport, environment, health care, and finance. The results show that the accessibility to health care and transport can positively affect land prices and the accessibility to environment (waste facilities and junkyard) and unpleasant services (funeral hall and charnel house) can negatively affect land prices. Especially, the accessibility to hospital is the most positive influential factor for all types of land usages.

  • The primary purpose of this study was to investigate the job characteristics and competencies of a head-cook in contracted foodservice management company, identify the knowledge, abilities, skills and other characteristics (KASO) required to perform the duties of a head-cook, and provide training content and develop training program for job of head-cook in contract foodservice management company (CFMC). A survey instrument including identified KASO was used in the study. The questionnaire was delivered by using e-mail to 165 head-cooks employed by CFMC. The factor analysis resulted in a three-factor structure of the instrument such as 'basic foodservice operation duties' 'personal characteristics' 'managing of expanded duties-menu, customer and business'. This result suggested the education and training program for head-cook in CFMC should be composed of 'basic foodservice operation duties' on 'bulk preparation', 'procurement, inventory management', 'facility and equipment management', and 'sanitation and safety management', 'personal characteristics' on 'personality management' and 'moral duties', and 'managing of expanded duties-menu, customer and business' on 'menu management', 'customer service management', 'cost management', and 'administrative ability'. Therefore, it will be expected that the management of human resources in the contract foodservice industry would be developed by the application of recommended education and training program.
