  • It is a common practice in Hong Kong for the main contractors of local building projects to sublet most of the work to subcontractors. Consequently their roles have gradually transformed from a constructor to a manager of subcontractors. The outcomes of a project therefore depend heavily on the subcontractors' performance. However, most of the subcontractors complain that they are unable to efficiently and effectively operate due to site coordination problems, such as inaccurate site reference lines, caused by main contractors. The site problems may consume significant amounts of resources if practical solutions cannot be agreed by the project participants early enough. Rahim Organizational Conflict Inventory-II (ROCI-II) model was developed by M.A. Rahim that measure five types of conflict management style including Integrating, Obliging, Dominating, Avoiding and Compromising. This paper presents the questionnaire survey based on the ROCI-II model to rank the preference on the conflict management style adopted by the project representatives of the subcontractors in handling the site coordination problems and its impact to the time used to agree the solutions to the different types of site coordination problems with main contractor. The survey results show that most of the subcontractors' project representatives preferred to adopt the Compromising style to tackle the site coordination problems and the time used to agree the solutions with main contractor was influenced by the conflict management style adopted.

  • An experiment was conducted to study the performance of broilers chicks (2 to 42 d of age) fed diets containing pearl millet (PM, Pennisetum typhoides), foxtail millet (FOM, Setaria italica) or finger millet (FIM, Elusine coracana) totally replacing (w/w) yellow maize (YM) with and with out supplementing non-starch polysaccharide (NSP) hydrolysing enzymes at the rate of 0.5 g/kg diet. Enzyme preparation contained amylase 2,400 units, hemi-cellulase 5,400 units, cellulase 12,000 units, protease 2,400 units and beta-glucanase 106 units/g. Each diet was fed to eight replicates (five female Vencob broilers/replicate) housed in stainless steel battery brooders. The estimated metabolizable energy (ME) contents of YM, PM, FOM and FIM were FM (PM) were about 3,389, 2,736, 3,303 and 2,846 kcal/kg, respectively. Total replacement of YM with FOM did not influence the body weight gain, ready to cook yield, relative weights of giblet, liver, intestine, lymphoid organs (bursa and spleen) and length of intestine, antibody titers and livability at 42 d of age. But the food efficiency decreased significantly in FOM fed broilers compared those fed YM. Further, the fat content in thigh muscle reduced with FOM fed groups compared to those fed YM. The performance of broilers decreased significantly in PM and FIM fed broilers compared to those fed YM. The relative weights of giblet, gizzard and liver increased in FIM fed groups compared to those fed YM as the principal source of energy in broilers. Incorporation of NSP hydrolysing enzymes in commercial broiler diets improved the efficiency of feed utilization during starter phase but not at 42 d of age. The results thus indicate that yellow maize can be replaced in toto on weight basis in commercial broiler diets without affecting the performance. Supplementation of NSP hydrolysing enzymes was beneficial in enhancing feed utilization during the starter phase.

  • An experiment was conducted to study the effect of replacing soyabean meal (SBM) at 50 and 100% with conventional (CMC) and low glucosinalate mustard cakes (LGMC) in iso-caloric and iso-nitrogenous diets in broiler chickens. All these diets contained 0.1% choline chloride with a purity of 50% (w/w). Another diet was prepared by replacing SBM in toto with CMC with no supplemental choline to find out the possible role of supplemental choline in mustard cake (MC) based diets. Two hundred and seventy day-old broiler chicks were distributed randomly in 54 stainless steel battery brooder pens of five chicks in each pen. Each experimental diet was allotted at random to nine battery brooders and offered ad-libitum from day 2 through 42 days of age. Body weight gain was significantly depressed by total replacement of SBM with either LGMC or CMC at 21 days of age. Non-supplementation of choline significantly depressed the growth compared to those fed CMC 100% with supplemental choline. However, at 42 days of age, such an effect was seen only with CMC. Replacement of SBM with CMC 100% with or without choline supplementation depressed the body weight gain. The concentrations of cholestorol and tryglicerides in serum and the relative weights of ready to cook yield, giblet and gizzard decreased by incorporation of mustard cakes in broiler diets. The trend in fat and protein contents in breast and thigh muscles and liver was not clearly attributable to the treatment effect. Based on the results, it is concluded that SBM can be replaced in toto with LGMC (535.0 and 466.5 g/kg starter and finisher diets, respectively) or up to 50% (215.0 and 186.7 g/kg starter and finisher diets, respectively) with CMC in commercial broiler chicken diets. Choline supplementation at 0.1% level in broiler diets containing CMC was found to be beneficial during starter phase.

  • Key Performance Indicators (KPIs) are the criteria of measuring project performance in order to attain construction excellence. Previous researchers have examined the abstract concept of success for general new construction and identified its relationship with the factors of success. In fact, most buildings exist to satisfy the needs of people. With the passing of time and change in technology, buildings have to be maintained and renovated in order to continue functioning properly for the benefits of users. Therefore, criteria and factors of success have increasingly attracted the attention of both researchers and practitioners, especially in cities where buildings become ageing. However, the topic of project success for maintenance projects is less discussed in previous research, and project participants, including maintenance surveyors should be able to identify the success measurement and its associated factors for performance improvement. This study fills the research gap by investigating the criteria and factors of success for maintenance projects. It first provides a summary of the literature review on the criteria and factors of success for construction projects. An empirical study has also been carried out with ten practitioners in Hong Kong to further identify the criteria and factors critical for the success of maintenance projects in practice. While most criteria and factors of success for new construction projects are also applicable to maintenance projects, participants in maintenance projects believe that effective communication is in particular important to provide quality service to the end-users.

  • The code division multiple access (CDMA) system capacity is limited by the amount of interference of the system. To reduce the unnecessary interference, this paper proposes optimized cell identification (ID) codes for site selection diversity transmission (SSDT) power control in wideband code division multiple access system of third generation partnership project (3GPP). The proposed SSDT cell ID codes are designed to minimize the problem and to be easily decoded using simple fast Hadamard transformation (FHT) decoder.

  • This paper explores the work of mourning of 9/11 in the United States, focusing on the project of building the National September 11 Memorial managed by the Lower Manhattan Development Corporation(LMDC) and the War on Terror declared by the George W. Bush administration in the wake of 9/11. This paper first looks at the project of building the Natioanl September 11 Memorial and considers what was at stake in achieving this project. It also examines the limitations of the project. This paper argues that, in spite of the efforts to mourn the victims in significant and meaningful ways, the work of mourning in the memorial project fails at least in two respects. First, the memorial project "began so soon" right after 9/11 that the victims' families were not given enough time to mourn their loved ones. Second, the project were permeated with American nationalism and patriotism, which made the 316 non-American victims of 9/11 invisible and forgotten. Then, it goes on to examine the War on Terror because the War on Terror epitomized the failure of mourning due to these causes. In his address to the nation delivered on the very day of 9/11, President George W. Bush stated that "America was targeted for the attack because we're the brightest beacon for freedom and opportunity in the world" and that the terrorists failed to threaten America into chaos. He also stated that America is in "the war against terrorism." These statements were a futile reassertion of the illusion of American invulnerability and a prohibition of mourning in favor of violent military responses to 9/11. American nationalism also underlies Bush's official naming of September 11 as "Patriot Day." The victims were sacrificed because they were at the site when terrorists attacked, which implies that their death had nothing to do with American patriotism. Naming September 11 as Patriot Day was an act of imbuing the absurdity of the victims' death with a false meaning and an act of forgetting the non-American victims. The failure of the work of mourning of 9/11 consisted in the inability to recognize human vulnerability and interdependence and the inability to mourn not only American victims but also non-American victims killed in 9/11 and the War on Terror. A meaningful and significant mourning could be possible when we realizes that all human beings are exposed to one another and their lives are interdependent on one another. September Eleventh Families for Peaceful Tomorrows well demonstrated this kind of mourning. When most Americans supported violent retaliations, Peaceful Tomorrows made pleas for nonviolent responses to 9/11. Turning their grief into action for peace, its members work "to create a safer and more peaceful world for everyone," not only for Americans. Their effort to mourn in meaningful and nonviolent ways delivers the message that a disaster like 9/11 should not happen anywhere.

  • We report on the growth, structural and transport properties of zinc-blende CrAs/GaAs/MnAs/GaAs multilayers on GaAs(001) substrates. Structural analyses using in-situ reflection high-energy electron diffraction and exsitu cross-sectional transmission electron microscopy confirmed the realization of a zinc-blende crystal structure. Room temperature Hall measurements reveal that the as-grown multilayer exhibits p-type conductivity with a very low resistivity of $0.052\;\omega{cm}$, a high carrier concentration of $6.2X10^{19}\;cm^{-3}$ and a Hall mobility of $1.8\;cm^2/Vs$. We also observed a clear decrease of the resistivity in samples after low temperature annealing.

  • The effects of $\beta$-(1,6)-galactosyl trehalose trisaccharide ($\beta$-GT) that was preferentially produced by Escherichia coli $\beta$-galactosidase on cryo- and thermo-protections of protein were investigated with those of other sugars at the level of 8% (w/v). As compared to a control without sugar additive, $\beta$-GT effectively enhanced 32-54% of the cryoprotection of fish actomyosin against repeated freeze-thawing and frozen storage, and also 49% of the protection against thermal inactivation of pyrophosphatase, respectively. As a result, it was significantly more effective than sorbitol and trehalose in both cryoprotection and thermoprotection. Thus, $\beta$-GT would be possibly applied as a sugar substitute for cryo- and thermo-protective applications of food protein.

  • This paper deals with the design of conductor stringing of KEPCO 765kV transmission line. The main subject in the design of conductor stringing is the determination on what the stringing tension is. According to the stringing tension, the weight and height of towers and the strength necessary for conductor, hardware, insulator vary, and the construction cost and the reliability of tower are affected largely. Therefore, in order to determine the optimum condition for stringing conductors, We appraised various items : estimation of economic comparision, strength appraisal of conductor, hardware, insulator, etc. After studying these entirely, we present the condition of condutor stringing for KEPCO 765kV transmission line.
