Purpose - This paper explores the perceptions held by native grocery shop-owners of their foreign counterparts to ascertain if there are lessons to be shared especially regarding operational/survival strategies. Research design, data and methodology - A questionnaire was used to collect data from 121 subjects who were purposively selected. The data was processed and analysed with the aid of Statistical Package for the Social Sciences(SPSS) software. Results - The study found that native South Africans hold the perception that immigrants have operational advantage over them. The study also found that with bulk buying, immigrants' stores stock a larger variety of groceries while their items are sold cheaper. It is also arguable from the standpoint of the findings that immigrant grocery store owners avoid expensive lifestyles which often is common among natives who own informal grocery shops. Conclusions - It is the position of this paper that adopting the strategies utilized by immigrant entrepreneurs, informal grocery shops owned by native South Africans are likely to see an improvement in their township-based grocery stores. A major merit of this study beyond its novelty is its potential to advance learnership and collaboration between immigrant entrepreneurs and their native counterparts.

In this study, the vertical characteristics of wind were analyzed using the horizontal wind, vertical wind, and vertical wind shear, which are generated from a wind profiler during concentrated heavy rain, and the quantitative characteristics of concentrated heavy rain were analyzed using CAPE, SWEAT, and SRH, among the stability indexes. The analysis of the horizontal wind showed that 9 cases out of 10 had a low level jet of 25 kts at altitudes lower than 1.5 km, and that the precipitation varied according to the altitude and distribution of the low-level jet. The analysis of the vertical wind showed that it ascended up to about 3 km before precipitation. The analysis of the vertical wind shear showed that it increased up to a 1 km altitude before precipitation and had a strong value near 3 km during heavy rains. In the stability index analysis, CAPE, which represents thermal buoyancy, and SRH, which represents dynamic vorticity, were used for the interpretation of the period of heavy rain. As SWEAT contains dynamic upper level wind and thermal energy, it had a high correlation coefficient with concentrated-heavy-rain analysis. Through the case studies conducted on August 12-13, 2012, it was confirmed that the interpretation of the prediction of the period of heavy rain was possible when using the intensive observation data from a wind profiler and the stability index.

The construction environment has been declared as a hazard prone area due to high number of accident and death. The study aims to identify influential factors that contribute to poor safety practices and its consequences on construction workers in Cape Coast Metropolis. Seventy respondents were taken as the sample size for the study. Descriptive analysis was used to analyze the data obtained from the field. Findings show that poor site management, working without safety gadgets, failure to use their Personal Protective Equipment (PPE) and negligence of workers were the main causes of accidents on sites. Poor site management had the highest ranking among the seven variables. Effects of poor safety practices on building construction site and delays in work execution were due to injury of workers, extra cost due to payment of compensation to injured victims, not motivated due to injury of worker and declined reputation of firm. Management team should motivate workers for safe work done, provide adequate PPE for their workers on site and have documented health and safety policy on site. Site authorities and management team should be on site regularly to ensure proper safety practices on construction site.

In this paper, we investigate a signal typing on the basis of visual impression of distinctive spectrogram. Pathological voices are classified into signal type 1, 2, 3, or 4 to estimate perturbation parameters and to mark perceptual rating based on Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). The results suggest that perturbation analysis can be applied to only type 1 and 2 signals and the perceptual ratings of overall grade increase with each signal type, overall. A good inter-rater reliability is showed among three raters. We recommend that pathological voices should be marked the signal typing and CAPE-V, together, to definitely describe the characteristics of pathological voices.

The main objective of the study is to find out the level of information-seeking behaviour of auto mechanics working at Siwdu and its impact on the work they do. Two methods of data collection instruments were used; these included a questionnaire and interview schedule. The researchers personally administered fifty-three questionnaires of which forty-eight completed ones were received. Twelve (12) people were interviewed at their respective workshops. The respondents were registered members of Siwdu Auto Mechanic Association and the total number of sixty respondents used represented 20% of total number of members. Quantitative data obtained mainly from the questionnaire were analysed using Statistical Package for Social Sciences (SPSS) software version 20. Responses for the interview were analysed thematically. Some of the major findings are as follows: The majority of the respondents did not know how to get information from the library; some of the respondents preferred consulting their "Masters" for help; majority of the respondents had Android phones but did not know how to access relevant information; respondents were aware of the benefits of authentic information; and respondents recommended that Management of libraries should organise seminars and workshops for auto mechanics to enable them know how and where to access information. Information is needed by everybody to enhance efficiency therefore creating the awareness of the sources of information is a way of increasing productivity. Knowing the level of information-seeking behaviour of people in every manner of job is essential in the nation's human resource development.

Homogot Lighthouse is located in Pohang of the easternmost of Korean Peninsula. Homogot has become first known as Cape Clonard in the West through the navigation log by La Perouse, a Frenchman who embarked on a global exploration in 1785. Homogot Lighthouse represents an outstanding accomplishment of modernization that numerous civilized countries scrambled to attain in the early 20^th century. Located where the geographical risk of earthquakes is high, the structure was nonetheless built to be 26.4m high with brick masonry. Structurally safe and aesthetically graceful, it demonstrates neoclassical ideas superbly in terms of style as well. Although the history of Asian lighthouses is shorter than that of European ones. Homogot Lighthouse, which demonstrates the history of a modern lighthouse along with those in Japan and China, is differentiated by the following characteristics. ① The 'living lighthouse heritage' is linked to one of the largest lighthouse museum in the world. ② Where you can see the earliest sunrise at the easternmost of the Eurasian Continent. ③ The completion of a modern-style lighthouse constructed at the easternmost of the Far East after being initiated in Europe. ④ Differentiated historical, architectural, and aesthetic value. ⑤ The heart of the national marine park.

The computer simulation model was used to forecast the concentrations of COD$_{cr}$, NH$_{4}$$^{+}$-N and NO$_{3}$$^{-}$-N in each reactors. In the biological wastewater treatment system, the computer simulation model was used to observe the behavior of pollutants especially. In this research, effect of SRT, feeding pattern and recirculation rate on UCT(University of Cape Town) process was evaluated by computer simulation model. T-N removal was affected to the SRT. SRT for effective T-N removal was 15 days or longer. Feeding pattern in UCT process was affected to the T-N removal. Feeding pattern which 100% loading to the first reactor was most effective for T-N removal. The effect of recirculation rate was clear for T-N removal. The recirculation from anoxic reactor to anaerobic reactor was not need but the recirculation from oxic reactor to anoxic reactor was need. In aspect of nitrogen removal efficiency, A/O process was higher than UCT process.

The work presented here focuses on the development of suitable discretised formulations, for large-displacement shape and non-shape design sensitivity analysis (DSA), which enable the straightforward incorporation of structural optimisation into established finite element analysis (FEA) codes. For the generalised displacement-based functional the design sensitivity vector has been expressed in terms of displacement sensitivity. The Total Lagrangian formulation is utilised for modelling of large deformation of truss structures. The variational formulation of the sensitivity analysis procedure is discretised by using "pseudo" - finite elements, Results are presented for the sensitivity analysis and optimisation of standard truss structures. For the purposes of this work, the analysis and optimisation procedures outlined below are incorporated into the FEA code ABAQUS.
