Transition of water demand and treatment plant overcapacity: a case study of the Seoul Metropolitan City, Korea

Lee S, Park H

Water Sci Technol, 2010;61(12):3129-40.
PMID: 20555209 DOI: 10.2166/wst.2010.454

This study deals with the overcapacity problem of water treatment plants in Korea, and mainly discusses status, causes, and engineering options. To this end, we first statistically analyze the recent trend of demand, revealing that the demands of small- and mid-size systems are still increasing while that of large-size systems is now decreasing. Since the existing approach to plan capacity implicitly assumes that demand will increase at a regular rate, we estimate excess capacities and system utilizations of large-size systems. From these results it is found that the large-size systems are suffering from serious overcapacity, thus necessitating that engineers make very difficult decisions given that systems are still expanding the capacities of plants due to a lack of awareness of the current demand trend. For other systems where there is a better understanding of the transition of demand, planners have ceased to expand plants or have closed down relatively old plants in efforts to reduce O&M costs. To address this problem, quick recognition of the transition of demand is being highlighted by the concepts of integrated resources management and cybernetics. Therefore, we examined how quickly the new trend of the Seoul case could be precisely recognized and appropriately addressed. Using the Bayesian parameter estimation method, we found that a new trend can be recognized six years after the transition of demand.

Jones JJ, Watkins PJ, Owyong LY, Loh PP, Kutty MK, Jogie B

Trop Geogr Med, 1978 Dec;30(4):439-49.
PMID: 749278

One hundred and thirty-two newly diagnosed Asian diabetic patients (39 Malay, 30 Chinese and 63 Indians) have been studied in Kuala Lumpur. The highest proportion of diabetic patients were Indian and the lowest were Chinese. Vascular complications were equally common in Asian diabetic patients as in Europeans; coronary heart disease was relatively more common in Indians and cerebral vascular disease in Chinese. Twenty percent of all Asian diabetic patients requiring admission to hospital also had coronary heart disease, 9% had cerebral vascular disease and 8% had gangrene or ulceration of the feet. In Kuala Lumpur, diabetes is a very important risk factor for coronary heart disease: 17% of all patients admitted to the General Hospital with coronary heart disease were already diabetic.

Fulltext Impact of London's low emission zone on air quality and children's respiratory health: a sequential annual cross-sectional study

Mudway IS, Dundas I, Wood HE, Marlin N, Jamaludin JB, Bremner SA, et al.

Lancet Public Health, 2019 Jan;4(1):e28-e40.
PMID: 30448150 DOI: 10.1016/S2468-2667(18)30202-0

BACKGROUND: Low emission zones (LEZ) are an increasingly common, but unevaluated, intervention aimed at improving urban air quality and public health. We investigated the impact of London's LEZ on air quality and children's respiratory health.
METHODS: We did a sequential annual cross-sectional study of 2164 children aged 8-9 years attending primary schools between 2009-10 and 2013-14 in central London, UK, following the introduction of London's LEZ in February, 2008. We examined the association between modelled pollutant exposures of nitrogen oxides (including nitrogen dioxide [NO2]) and particulate matter with a diameter of less than 2·5 μm (PM2·5) and less than 10 μm (PM10) and lung function: postbronchodilator forced expiratory volume in 1 s (FEV1, primary outcome), forced vital capacity (FVC), and respiratory or allergic symptoms. We assigned annual exposures by each child's home and school address, as well as spatially resolved estimates for the 3 h (0600-0900 h), 24 h, and 7 days before each child's assessment, to isolate long-term from short-term effects.
FINDINGS: The percentage of children living at addresses exceeding the EU limit value for annual NO2 (40 μg/m3) fell from 99% (444/450) in 2009 to 34% (150/441) in 2013. Over this period, we identified a reduction in NO2 at both roadside (median -1·35 μg/m3 per year; 95% CI -2·09 to -0·61; p=0·0004) and background locations (-0·97; -1·56 to -0·38; p=0·0013), but not for PM10. The effect on PM2·5 was equivocal. We found no association between postbronchodilator FEV1 and annual residential pollutant attributions. By contrast, FVC was inversely correlated with annual NO2 (-0·0023 L/μg per m3; -0·0044 to -0·0002; p=0·033) and PM10 (-0·0090 L/μg per m3; -0·0175 to -0·0005; p=0·038).
INTERPRETATION: Within London's LEZ, a smaller lung volume in children was associated with higher annual air pollutant exposures. We found no evidence of a reduction in the proportion of children with small lungs over this period, despite small improvements in air quality in highly polluted urban areas during the implementation of London's LEZ. Interventions that deliver larger reductions in emissions might yield improvements in children's health.

Variation in UK Deanery publication rates in the British Journal of Oral and Maxillofacial Surgery: where are the current 'hot spots'?

Turner J, Hammond D, Goodson M

Br J Oral Maxillofac Surg, 2021 02;59(2):e48-e64.
PMID: 33109382 DOI: 10.1016/j.bjoms.2020.08.090

Publication in peer-reviewed journals is often seen as a cornerstone of the academic and clinical career within medicine and surgery. As one of the largest circulations in oral and maxillofacial surgery, the British Journal of Oral and Maxillofacial Surgery (BJOMS) offers trainees and consultants the opportunity to disseminate valuable information worldwide. The aim of this paper is to investigate the variation in publication rates of U.K. authors based upon their Deanery in order to identify potential hotspots. All volumes of BJOMS between 2011 and 2019 were hand searched to identify full articles authored by authors in U.K., these were categorised by Deanery and allocated a theme within OMFS. The results demonstrate that, of the 378 full length articles, over 30% of these were from two Deaneries: London and North West (West). Oncology, OMFS training and education, and craniofacial trauma were the three most common themes of publication amounting to 51.5% of total publications. There has been an unfortunate decrease in publications from U.K. Deaneries of almost 30% from 2011 to 2019 which begs the question of whether fewer publications are being accepted or if rates of submission have reduced.

Planning Accessibility Strategies and Connectivity for Malaysian Urban Built Environment

Abd Samad NA, Said I, Abdul Rahim A

Stud Health Technol Inform, 2018;256:367-377.
PMID: 30371497

Access to our buildings relies to the accessibility of its external environment and the route taken. Developments and planning in urban areas has many several requirements and restrictions. Planning accessibility for Malaysian built environment is achievable by designing in compliance to the requirements enforced by authorities. Accessible design is commonly associated with providing facilities for Persons with Disabilities (PwDs), the issue that is often brought up is the inaccessibility of the external environment and lacking of seamless connectivity between buildings and the outdoor. The intention is to formulate accessibility strategies and work out planning process on how accessibility can be achieved. Universal Design will be the basis for the design and planning concept to accommodate all users to enjoy our urban built environment. It is notable that developed countries advances more in terms of implementing and enforcing accessibility measures via legislative and regulatory documents, government strategies and initiatives within its planning approach than the developing nations. The methodology will be looking into the establishment of strategies and measures of international and local planning policy, local and action plans of City of London as selected Local Authority to be analyzed its inclusive policy has been successfully implemented in their jurisdiction. The findings, discussions and result will be an outcome of generating a framework of accessibility strategies that is derived from interviews and government documents accordingly to targeted Malaysian urban areas focusing the City of Petaling Jaya and Putrajaya and how it can be improvised. Therefore, an interpretation of adopting accessibility planning strategies of developed country, to be adapted locally according to Malaysian legislation, culture and lifestyles.

Correlating Streptococcus mutans counts in saliva with plaque amount, gingival inflammation and caries experience in school children

Jalil RA

Singapore Dent J, 1995 Jul;20(1):16-20.
PMID: 9582684

Samples of stimulated whole saliva were obtained from ninety-four 12-14-year-old school children living in inner London to evaluate if there was a correlation between Streptococcus mutans counts in saliva with plaque amount, gingival inflammation and caries experience. S. mutans counts were obtained by a dip-slide method (Dentocult 'Strip Mutans') in which the count was expressed as 0, 1, 2, 3, or 4 based on visual estimation of the colony density. There was no association between counts' of S. mutans in saliva with plaque amount and gingival inflammation. However, there was a significant trend of increased decayed, missing, filled surfaces (DMFS) with increasing S. mutans counts.

Fulltext Surface Thermo-Dynamic Characterization of Poly (Vinylidene Chloride-Co-Acrylonitrile) (P(VDC-co-AN)) Using Inverse-Gas Chromatography and Investigation of Visual Traits Using Computer Vision Image Processing Algorithms

Kakani V, Kim H, Basivi PK, Pasupuleti VR

Polymers (Basel), 2020 Jul 23;12(8).
PMID: 32717780 DOI: 10.3390/polym12081631

The Inverse Gas Chromatography (IGC) technique has been employed for the surface thermo-dynamic characterization of the polymer Poly(vinylidene chloride-co-acrylonitrile) (P(VDC-co-AN)) in its pure form. IGC attributes, such as London dispersive surface energy, Gibbs free energy, and Guttman Lewis acid-base parameters were analyzed for the polymer (P(VDC-co-AN)). The London dispersive surface free energy ( γ S L ) was calculated using the Schultz and Dorris-Gray method. The maximum surface energy value of (P(VDC-co-AN )) is found to be 29.93 mJ·m - 2 and 24.15 mJ·m - 2 in both methods respectively. In our analysis, it is observed that the γ S L values decline linearly with an increase in temperature. The Guttman-Lewis acid-base parameter K a , K b values were estimated to be 0.13 and 0.49. Additionally, the surface character S value and the correlation coefficient were estimated to be 3.77 and 0.98 respectively. After the thermo-dynamic surface characterization, the (P(VDC-co-AN)) polymer overall surface character is found to be basic. The substantial results revealed that the (P(VDC-co-AN)) polymer surface contains more basic sites than acidic sites and, hence, can closely associate in acidic media. Additionally, visual traits of the polymer (P(VDC-co-AN)) were investigated by employing Computer Vision and Image Processing (CVIP) techniques on Scanning Electron Microscopy (SEM) images captured at resolutions ×50, ×200 and ×500. Several visual traits, such as intricate patterns, surface morphology, texture/roughness, particle area distribution ( D A ), directionality ( D P ), mean average particle area ( μ a v g ) and mean average particle standard deviation ( σ a v g ), were investigated on the polymer's purest form. This collective study facilitates the researches to explore the pure form of the polymer Poly(vinylidene chloride-co-acrylonitrile) (P(VDC-co-AN )) in both chemical and visual perspective.

Fulltext Effects of Air Pollution and the Introduction of the London Low Emission Zone on the Prevalence of Respiratory and Allergic Symptoms in Schoolchildren in East London: A Sequential Cross-Sectional Study

Wood HE, Marlin N, Mudway IS, Bremner SA, Cross L, Dundas I, et al.

PLoS One, 2015;10(8):e0109121.
PMID: 26295579 DOI: 10.1371/journal.pone.0109121

The adverse effects of traffic-related air pollution on children's respiratory health have been widely reported, but few studies have evaluated the impact of traffic-control policies designed to reduce urban air pollution. We assessed associations between traffic-related air pollutants and respiratory/allergic symptoms amongst 8-9 year-old schoolchildren living within the London Low Emission Zone (LEZ). Information on respiratory/allergic symptoms was obtained using a parent-completed questionnaire and linked to modelled annual air pollutant concentrations based on the residential address of each child, using a multivariable mixed effects logistic regression analysis. Exposure to traffic-related air pollutants was associated with current rhinitis: NOx (OR 1.01, 95% CI 1.00-1.02), NO2 (1.03, 1.00-1.06), PM10 (1.16, 1.04-1.28) and PM2.5 (1.38, 1.08-1.78), all per μg/m3 of pollutant, but not with other respiratory/allergic symptoms. The LEZ did not reduce ambient air pollution levels, or affect the prevalence of respiratory/allergic symptoms over the period studied. These data confirm the previous association between traffic-related air pollutant exposures and symptoms of current rhinitis. Importantly, the London LEZ has not significantly improved air quality within the city, or the respiratory health of the resident population in its first three years of operation. This highlights the need for more robust measures to reduce traffic emissions.

Fulltext Humans as animal sentinels for forecasting asthma events: helping health services become more responsive

Soyiri IN, Reidpath DD

PLoS One, 2012;7(10):e47823.
PMID: 23118897 DOI: 10.1371/journal.pone.0047823

The concept of forecasting asthma using humans as animal sentinels is uncommon. This study explores the plausibility of predicting future asthma daily admissions using retrospective data in London (2005-2006). Negative binomial regressions were used in modeling; allowing the non-contiguous autoregressive components. Selected lags were based on partial autocorrelation function (PACF) plot with a maximum lag of 7 days. The model was contrasted with naïve historical and seasonal models. All models were cross validated. Mean daily asthma admission in 2005 was 27.9 and in 2006 it was 28.9. The lags 1, 2, 3, 6 and 7 were independently associated with daily asthma admissions based on their PACF plots. The lag model prediction of peak admissions were often slightly out of synchronization with the actual data, but the days of greater admissions were better matched than the days of lower admissions. A further investigation across various populations is necessary.

The development and comprehensibility of a pictorial asthma action plan

Roberts NJ, Mohamed Z, Wong PS, Johnson M, Loh LC, Partridge MR

Patient Educ Couns, 2009 Jan;74(1):12-8.
PMID: 18789626 DOI: 10.1016/j.pec.2008.07.049

OBJECTIVE: Written action plans are regarded as an important part of asthma self-management education and yet they may not be understood by those with limited literacy skills. This study was designed to produce an understandable pictorial asthma action plan.
METHODS: With advice from a group of doctors and nurses a "standard" written action plan was translated by a medical artist into a series of pictorial images. These were assessed using the techniques of guessability and translucency by a series of adults attending a specialist asthma clinic in London and the same process was subsequently used to assess comprehensibility of the images and plans amongst a group of Somalis living in Manchester, UK and Malaysians in Seremban, Malaysia.
RESULTS: Guessability testing showed that the majority of pictograms were well understood by each of the study groups. Translucency testing revealed close agreement with intended meaning for the majority of the images. One image, depicting extra use of reliever medication scored less well in all populations; two other images scored less well in the Somali and Malaysian groups and reflect less use of certain inhaler devices in other countries. The overall plan was well understood by all patients who were able to adequately recount the appropriate actions to take in different clinical scenarios.
CONCLUSION: We have developed a pictorial asthma action plan understandable by 3 different populations of patients with asthma.
PRACTICE IMPLICATIONS: Pictorial representations have been shown by other studies in other situations to be an effective method of reinforcing the spoken word. The pictorial asthma action plan developed for this study has been shown to be comprehensible, personalised to the individual in the usual fashion. It is now suitable for further evaluation in clinical practice.

MyJurnal

Fabian Society is a type of political think tank which was founded by a group of students and
intellectuals at London School of Economics (LSE), United Kingdom in the late of 19 centuries. The
Fabian political thought is a new manifestation of socialist ideology in United Kingdom emerged through the role of Labour Party Partiat that time. After the World War II, the influence of this political
thought began to widespread throughout Malaya via British-educated Malayan students. This
development brought about a new form of political idealism based on social-democrat orientation
which emphasized on class struggles and civil issues in Malaya. Thus, the aim of this article is to
scrutinize objectively and descriptively the influence of the Fabian political thought in the Malaysian
political development from 1952 to 1970. Using the approach of history reconstructionist, the analysis
discussion was developed based on the use of primary sources as the argument base. The research
findings indicate that the influence of the Fabian political thought developed in Malaya by the role of
the socialist intellectual-progressive group throughout the research. The development did not only
involve labour movements and left-wing political parties such as Malayan Democratic Union (MDU)
and the Malayan Labour Party, but it also influenced students movements at universities through
University of Malaya Socialist Club in Singapore around 1950s and students societies in Universiti
Malaya, Kuala Lumpur around 1960s. In fact, at the same time the progressive Fabian group slipped in
right-conservative group through their direct involvement in UMNO and the Perikatan regime at the
time. This indirectly proves that there is a different side of the socialist role through the role of the
Fabian group in the development of democracy and politics in Malaysia.

Fulltext The impact of plurality in Malaysia-Singapore relations post Malaya

Ayu Nor Azilah Mohamad, Mohamed Ali Haniffa, Wayu Nor Asikin Mohamad

Malaysian Journal of Social Sciences and Humanities, 2018;3(3):53-63.
MyJurnal

This article discusses the impact of plurality on Malaysia-Singapore relations after the formation of
Malaysia on September 16, 1963. The establishment of the Federation of Malaysia agreement was
signed in London on July 8, 1963 by the representatives of the British government, the Federation of
Malaya, Singapore, Sabah and Sarawak. All parties agreed to the change in name from Federation of
Malaya to Malaysia. The declaration of Malaysia was made on September 16, 1963 simultaneously
throughout the country. This study uses secondary sources and library research methods. The findings
show that Singapore's existence in Malaysia was seen to have raised racial issues leading to the
separation of Singapore from Malaysia on August 9, 1965. Ethnic-related problems need to be
addressed wisely in order to not be a threat to racial relations among the plural society in Malaysia.

PMID: 1452782 DOI: 10.1136/jcp.45.11.1036

A throat swab from a 9 year old girl with pharyngitis yielded a non-toxigenic strain of Corynebacterium diphtheriae var mitis and Streptococcus group G. C pseudodiphtheriticum was isolated from the throats of two of her four brothers. In each case the isolate was sent to the reference laboratory before full identification. The growth was found to be mixed for one brother; the other isolate being a toxin producing C diphtheriae var gravis. The child was asymptomatic and the case proves that all colonial types on the Hoyles plate should be identified.
