Gastric carcinoma rarely presents as a perforation, but when it does, is perceived as advanced disease. The majority of such perforations are Stage III/IV disease. A T1 gastric carcinoma has never been reported to perforate spontaneously in English literature. We present a 56 year-old Chinese male who presented with a perforated gastric ulcer. Intra-operatively, there was no suspicion of malignancy. At operation, an open omental patch repair was performed. Post-operative endoscopy revealed a macroscopic Type 0~III tumour and from the ulcer edge biopsy was reported as adenocarcinoma. Subsequently, the patient underwent open subtotal gastrectomy and formal D2 lymphadenectomy. The final histopathology report confirms T1b N0 disease. The occurrence of a perforated early gastric cancer reemphasises the need for vigilance, including intra-operative frozen section and/or biopsy, as well as routine post-operative endoscopy for all patients.

The methodology for modeling building energy consumption is well established for energy saving calculation in the temperate zone both for performance-based energy retrofitting contracts and measurement and verification (M&V) projects. Mostly, statistical regression models based on utility bills and outdoor dry-bulb temperature have been applied to baseline monthly and annual whole building energy use. This paper presents the application of neural networks (NN) to model landlord energy consumption of commercial buildings in Singapore. Firstly, a brief background information on NN and its application on the building energy research is provided. Secondly, five commercial buildings with various characteristics were selected for case studies. Monthly mean outdoor dry-bulb temperature ($T_0$), Relative Humidity (RH) and Global Solar Radiation (GSR) are used as network inputs and the landlord monthly energy consumption of the same period is the output. Up to three years monthly data are taken as training data. A forecast has been made for another year for all the five buildings. The performance of the NN analysis was evaluated using coefficient of variance (CV). The results show that NNs is powerful at predicting annual landlord energy consumption with high accuracy.

The research aims to help merchant acquiring institutions gain a better insight on what merchant establishments in the Singapore market perceive of the costs they incur due to credit card acceptance. The research attempts to study the Singapore market and establish if increased credit card usage does increase costs for the merchant establishments that accept credit cards, this will help to acquire institutions in Singapore have a better understanding of merchant perceptions and what drives or deters credit card acceptance in the Singapore market. The survey was based on an interview of merchant establishments and the views of the merchants and was not based on their financial data. As a first step, the variables used in the survey were tested for interdependence using Chi-square tests; subsequently data reduction using factor analysis was performed and finally linear regression to establish a relation between dependent and independent variables. Merchant establishment believe accepting credit cards and increasing volume is costlier compared to another form of payment, but have mixed awareness about interchange fee. It also indicated that interchange fee and cardholder benefits are independent of the merchant establishments. The study only broadly attempts to gauge merchants view if increased credit card usage has increased costs for them.

There has been a pronounced increase in research and development (R&D) expenditure in Singapore over the last two decades, with government spending accounting for a sizeable share. This increase has been spurred by public policy emphasis on research and innovation as engines of economic growth. This paper analyses the impact of R&D on economic performance in Singapore from 1978 to 2012 through the use of time series analysis. The Cobb-Douglas based analysis shows a long-run equilibrium relationship between Total Factor Productivity (TFP) and R&D investments. We found that the short-run productivity of R&D in Singapore is comparable to smaller advanced economies in the Organisation for Economic Co-operation and Development (OECD). However, in terms of long-run R&D productivity, Singapore lags slightly behind the smaller OECD nations and far behind the G7 countries. This suggests leakage of value capture and low absorptive capacity in local firms. Possibility of productivity improvements induced by policy changes in the 1990s was considered, but no evidence of significant structural breaks was found. Lastly, Granger causality analysis reveals that public sector R&D augments private sector R&D capital, thus playing an important role in generating externalities and spillover effects. Policy implications and lessons for other middle-income countries are discussed.

According to this study, overall economic impacts of the FTA between Korea and Singapore upon fish and fishery products of our country were likely to be very small and insignificant. When the tariff on fish and fishery products between the two borders were completely eliminated, if no roundabout exports from other ASEAN countries were practicing, then this study calculated that the increase of imports from Singapore in the 12 chief items was estimated to be only about 250,000kg, which comes to the amount of 1.1 billion won. The 12 items used here account for over 90% imports of fish and fishery products from Singapore. This study also revealed that imports of fish and fishery products from Singapore would be substituted for domestic products more than 100,000kg in the 7 items produced domestically. The substitution effect represents fishermen's demage by replacing domestic products by imports in terms of income which comes to the amount of 438 million won. As the results of the study shows, establishing an FTA between the two countries will not exert so much adverse effects on our fisheries because relative importance of fish and fishery products in both countries are very small. But the contents of the agreement on fish and fishery products between the two countries are very important, as concluding the negotiation and signing the agreement between Korea and Singapore would be a precedent in future negotiations with other asian countries, especially with China and ASEAN countries.

Public private partnership (PPP) procurement was introduced into Singapore in 2003, and 10 PPP projects was successfully completed and have been in operation. The objective of this study is to identify the critical risk factors and risk allocation preferences for PPP projects in Singapore. To achieve this objective, a comprehensive literature review was carried out and 42 risks were identified and grouped into three meta levels, i.e. macro, meso and micro levels. The questionnaire survey produced 48 completed questionnaires from 48 different contractors. The survey results indicated that 23 risk factors had significantly high criticalities and that four macro-level risks, four meso-level risks and two micro-level risks were among the top 10 risk ranking. "Lack of support from government", "availability of finance" and "construction time delay" were perceived as the top three critical risks. Also, the result implied that micro-level risks had a higher criticality mean score than macro-level and meso-level risks. The findings of this study help both public and private sectors to better understand the risks and their allocation in PPP projects, providing valuable information for organizations that intend to participate in PPP projects in Singapore.

Investigation of the genetic functions in complex biological systems is a challenging step in recent year. Hence, several valuable and interesting research projects have been developed with novel ideas to find out the unknown functions of genes or proteins. To validate the applicability of their novel ideas, various approaches are built up. To date, the most promising and commonly used approach for discovering the target proteins from biological system using small molecule is well known a forward chemical genetics which is considered to be more convenient than the classical genetics. Although, the forward chemical genetics consists of the three basic components, the target identification is the most challenging step to chemical biology researchers. Hence, the diverse target identification methods have been developed and adopted to disclose the small molecule bound protein. Herein, in this review, we briefly described the first two parts chemical toolbox and screening, and then the target identifications in forward chemical genetics are thoroughly described along with the illustrative real example case study. In the tabular form, the different biological active small molecules which are the successful examples of target identifications are accounted in this research review.
