Authors: Pai Vijaya H. , Rao Krishna A. , Bhandary Sulatha V.
Published: October 2019

Dacryocystectomy is the surgery of choice for elderly patients with chronic dacryocystitis with a fibrotic sac. Although a simple procedure, it can cause serious complications (however rare) such as visual impairment. A 65-year-old woman who underwent bilateral dacryocystectomy is described. On the first postoperative day, she complained of pain in her left eye. Her visual acuity was light perception in the left eye. Computed tomography scan of the orbit revealed a retrobulbar hematoma on the left eye. The hematoma was drained, but the patient did not regain vision. A rare complication of visual loss following dacryocystectomy is described. [Ophthalmic Surg Lasers Imaging 2006;37:494-496.]

Optical Coherence Tomography in Progressive Outer Retinal Necrosis
Authors: Narayanan R. , Kuppermann Baruch D.
Published: October 2019

A 38-year-old man with human immunodeficiency virus was referred for evaluation of retinal lesions in both eyes. Optical coherence tomography was performed after dilating the pupils. Biomicroscopy of the retina showed an atypical, solitary, yellowish-white lesion in the macula of both eyes with no inflammation of the vitreous. Optical coherence tomography of the lesions showed an area of extremely low reflectivity with well-defined but irregular borders in the outer retina. The surrounding retina showed normal reflectivity and was of normal thickness. Optical coherence tomography showed selective necrosis of the outer layers due to progressive outer retinal necrosis. Optical coherence tomography may serve as a useful tool for the early diagnosis of progressive outer retinal necrosis.

A Surgical Technique to Protect the Macular Hole in Indocyanine Green-Assisted Vitrectomy
Authors: Saito Masaaki , Iida Tomohiro
Published: October 2019

To prevent indocyanine green (ICG) toxicity during macular hole repair, a surgical technique was designed in which the hole is protected by a viscoelastic material before injecting ICG to stain the internal limiting membrane. The area covered by the viscoelastic material was not stained by ICG. The internal limiting membrane was peeled without difficulty by taking advantage of the ICG stain outlining it. After surgery, all holes closed and the postoperative outcomes were favorable. Only a small amount of residual ICG remained in the macular area. This surgical technique does not interfere with internal limiting membrane peeling and reduces the residual ICG postoperatively.

Authors: Rodriguez Andrés A. , Olson Michael D. , Miller Kevin M.
Published: October 2019

BACKGROUND AND OBJECTIVES  To determine differences in the amount of work involved in caring for functionally monocular patients who undergo cataract surgery compared with binocularly sighted patients.  PATIENTS AND METHODS  This was a retrospective study that included 100 consecutive functionally monocular patients and 100 binocularly sighted control patients matched by age (± 5 years) and date of surgery (± 1 year). Office records were reviewed to determine several measures of office and operating room work effort.  RESULTS  There was no difference between groups in preoperative telephone calls (P = .136), postoperative telephone calls (P = .580), preoperative office visits (P = .875), postoperative office visits (P = .601), or the number of times surgery was scheduled (P = 1.00). Monocular patients required more time for surgery (37.4 minutes) than binocular patients (32.4 minutes) (P = .010).  CONCLUSIONS  It takes longer to perform cataract surgery on functionally monocular patients than on binocularly sighted patients.

Authors: Dardabounis Doukas , Ioannakis Konstantinos , Detorakis Efstathios , Afendoulidis Evangelos , Kozobolis Vasilios P.
Published: October 2019

Acute angle-closure glaucoma due to vitreous prolapse immediately following neodymium:YAG (Nd:YAG) laser posterior capsulotomy in eyes with posterior chamber intraocular lens implants is rare. Previously described cases were associated with advanced age, excessive amounts of laser energy, and a large-diameter capsular opening. The authors describe a case of acute angle-closure glaucoma occurring 21 days after Nd:YAG laser posterior capsulotomy in a young patient with a small-diameter capsule opening and a small amount of laser energy to stress the importance of close extended follow-up even in eyes with a theoretical low risk for this complication.

Successful Removal of a Large Conjunctival Cyst Using Colored 2.3% Sodium Hyaluronate
Authors: Kobayashi Akira , Sugiyama Kazuhisa
Published: October 2019

A 39-year-old woman was referred for the management of a large conjunctival cyst in her right eye. A mixture of trypan blue and 2.3% sodium hyaluronate was injected into the cyst using a 27-gauge needle to achieve a complete removal of the cyst. This new technique provided excellent visualization to achieve an easy and complete resection of the large conjunctival cyst. Colored 2.3% sodium hyaluronate is effective in delineating the capsule and preserving its integrity during the removal of a large conjunctival cyst. Such a technique may also have a role in facilitating visualization and excision of other cystic lesions from the ocular surface.

The Impact and Outcomes of Integrating Health Literacy Education Into Adult Basic Education Programs in Boston
Authors: Hohn Marcia Drew , Rivera Lorna
Published: October 2019

Background:

Adult basic education (ABE) is the national system that offers educational services in English language development, reading, writing, math, technology, and communications to adults with low literacy, limited English, or both. These services range from basic levels to high school equivalency, with specialty programs in transition to community colleges and family literacy.

Objective:

This study sought to analyze the role of ABE in increasing health literacy among low literate and limited English populations and to identify effective models for teaching and learning about health in this setting.

Methods:

During a 2-year period, 90 students from three ABE programs in Boston participated in health literacy classes focused on healthy eating and received prevention screening services through local public health organizations. The majority of students classified themselves as Black, African American, or Latino. Participants ranged in age from 18 to 35 years; 64% of the participants were women. The three research sites were located in the Roxbury neighborhood of Boston, where health disparities and poverty rates are disproportionately high. During the study period, researchers conducted semi-structured interviews with teachers (
N
= 12) from each of the participating classrooms to gather information about the students in their health classes. Researchers also conducted semi-structured interviews and focus groups (
N
= 9) with students at each site during the study period to examine how they described changes in their knowledge, attitudes, and actions regarding health. Researchers also conducted ethnographic field research by observing health classes at each site, which was supplemented by collecting teachers' lesson plans as well as materials produced by learners.

Key Results:

ABE programs are a good setting for adults with limited literacy or limited English to increase their health literacy. The programs, which provide steady learning environments over time with staff skilled in adult learning, allow students to engage with health information in the context of their everyday lives, thereby increasing the likelihood of healthier practices.

Conclusions:

ABE programs play a vital role in developing health literacy among low literacy populations and are part of the solution for addressing health disparities.

Plain Language Summary:

This article describes the role that adult basic education plays in improving health literacy among low-literate and limited English populations. The impact and outcomes of learning about health were investigated for 90 adults in three programs in Boston where health disparity is high. The impact of different teaching/learning models also was compared.
Gamification and Student Engagement with a Curriculum-based Measurement System
Authors: Yan Yu , Hooper Simon , Pu Shi
Published: October 2019

In this study, we employed a random control experiment to evaluate the effectiveness of gamification (e.g. scores, goal, progressive bar, etc.) and initial task difficulty on college student engagement in computer-based assessments. A group of Chinese college students (N=97) were randomly assigned to four groups obtained by crossing the two independent variables: gamification (with or without) and initial difficulty level (low or normal). The experiment lasted for 35 minutes, and each student was asked to complete several mini-tests (named maze tests). Student engagement was measured by the average off-task time between two maze tests. The results showed that both gamification and low-difficulty entry level reduced students’ off-task time.  However, the gamification effect was only significant for male students but not for female students. The study also demonstrated that the maze test can be a potential method to predict the general English proficiency with Chinese English language learners.
Enhancing Professional Learning Through Mobile Devices for Pre-Service Teachers in Remote Communities
Authors: Townsend Philip Bruce
Published: October 2019

This article details the construction of a Grounded Theory to explain the concept of enhancing professional learning through mobile devices. The research data was delimited to the behaviours and beliefs of Aboriginal and Torres Strait Islander pre-service teachers enrolled in two community-based initial teacher education programs in very remote communities in Australia. Four educational uses of mobile devices were identified: accessing content, handling administration, collaborating for academic support and sharing personal encouragement. The use of mobile devices enabled adults to choose times of study, choose places of study, complete assessment relevant to their course and achieve a career goal. Three elements that impact the educational use of mobile devices were identified (i.e. context, precursors and catalyst). Seven categories underlie the concept of enhancing professional learning through mobile devices: fostering access, facilitating customisation, promoting collaboration, supporting relevance, completing the course, empowering agency and enabling networking.
Higher Education Abroad
Authors: Arae Khalid , Haj-Yehia Kussai
Published: October 2019

Through an investigation tracing the historical origins and trends associated with the Palestinian Minority in Israel (PAMI), this chapter investigates why a large proportion of those students—33% in fact—now choose to study abroad. Data are drawn from official statistics, documents and representative studies of PAMI students' to thus enable the authors to identify key factors that hinder PAMI access to Higher Education (HE) in Israel. Limited access to HE in the State of Israel is a strong motivator for PAMI students studying abroad, as it provides greater opportunity to pursue HE. This chapter discusses the features of globalization that have led to the development of a highly competitive international academic market and the effect that this has had on PAMI students' choice of location for HE and also choice of chosen field of study.
The Role of Indigenous Knowledge System in African Development
Authors: Akinwale Akeem Ayofe
Published: October 2019

This paper examines the relevance of Indigenous Knowledge System (IKS) for African development, using qualitative data. The findings revealed that wholesale adoption of foreign ideas has rendered Africans subservient in the world, despite their rich cultural heritage. This situation promotes substitution of IKS, the foundation of African progress, thereby creating more problems for Africans. Yet, IKS still provides succour for the majority of Africans. The emerging culture of individuality and nuclear family is not realistic in Africa where social structures largely reflect kinship solidarity and communalism sustained by social capital, which has become widely recognised. It is therefore suggested that Africans should revise their local circumstances to prevent further plunder of Africa. Also, there is urgent need for adaptation of African IKS to modern reality because the conditions that sustained it have been modified. Rather than focus on wholesale adoption of western remedies, Africans need to explore their IKS to promote common understanding in the context of contemporary globalisation. Africans at home and those in the Diaspora should utilise their abundant natural resources and human capital to repair the dented image of Africa. An upgraded version of African IKS can drive and sustain this mission.
Indigenous Knowledge Discourses in Africa
Authors: Masuku Mehluli
Published: October 2019

Since around the 1980s, the aspect of indigenous knowledge (IK) has attracted the attention of a number of experts, including culturists, politicians and information scientists. This has seen the mushrooming of literature on the subject matter from the afore-mentioned practitioners and specialists, with each discipline witnessing a certain “discourse”. This has also witnessed almost everyone in these disciplines glorifying African IK. Against this background, this chapter discusses the IK discourses in Africa, highlighting some of the significant trends and relationships among practitioners and scholars in the fields of culture, politics and information science that are driven by shared philosophies of IK. This paper is theoretical in nature and draws from the literature on IK to explain and demonstrate what the author calls the “IK discourses and “IK frenzy”, and explains the point of intersection by culturists, politicians and information science practitioners.
Challenges and Perspectives of Language Education Technology in Brazil
Authors: Bodah Eliane Thaines , Alldredge Josh Meuth , Bodah Brian William , Neckel Alcindo , Goellner Emanuelle
Published: October 2019

Our chapter aims to explore the challenges, advances, and perspectives of language-education technology in Brazil. Language-education is an extremely important topic for Brazil because many indigenous languages are nearing extinction due to the legacies of colonization and the fact that Portuguese, the national language of Brazil, is the only official language and thus the single most utilitarian method of communication. This issue is further complicated by Brazil's increasingly globalized economy, which, for many individuals, demands the acquisition of a foreign language in order to compete. The English language has been introduced into the curriculum of the vast majority Brazilian public schools over the course of the past few decades. Additionally, several private, for-profit English learning enterprises now have widespread services throughout the country. But rates of English (and even Portuguese) fluency still vary greatly among the population. This raises a number of critical questions that will be discussed in this work. Why is learning a new language such a challenge? Which methodologies can be utilized to increase language acquisition and build fluency? What are the new technologies that are used in teaching a second language in Brazilian schools, and how is their impact being measured? Are Brazilian teachers prepared to integrate new technologies and innovative methods of teaching and learning? Our methodology involves bibliographical research including a literature review, a case-study, and participatory research through semi-structured interviews. Our results have shown that several technologies are being implemented in Brazil, and that as a theoretical framework, educational communication has been recognized as a powerful tool to incorporate such technologies in language education. Overall, the use of learning technologies is common and growing among students, while it is increasing at a more institutional pace among teachers.
Language, Participation, and Indigenous Knowledge Systems Research in Mqatsheni, South Africa
Authors: Khupe Constance
Published: October 2019

This chapter is informed by findings from a science education interpretive study carried out in collaboration with an isiZulu-speaking community. Indigenous languages constitute intellectual and cultural resources that are important for local communities and for the society. The author argues for the recognition of indigenous languages as part of the call to decolonize research methodologies. The chapter positions research among indigenous peoples in the context of social justice and human rights, and shows how language fits in the transformation agenda. Drawing from findings from a research study carried out with a community in rural KwaZulu-Natal, the author asserts that the inclusion of indigenous languages in research frameworks contributes to meaningful participation, strengthens collaboration and facilitates the generation of authentic data.
Gender and Ethnic Discrimination
Authors: Jahan Ferdous , Wahab Sharif Abdul , Hafiz Fairooz Binte
Published: October 2019

Socioeconomic inequality among men and women is a major hindrance in ensuring equal advancement for all human being to live a dignified life. Minority status of women further exacerbates inequalities faced by women belonging to small ethnic groups. The chapter explores gender inequality across three small ethnic minorities' groups in Bangladesh. Applying Nussbaum's capability approach to analyze the situation of women with different social and ethnic identities, this chapter unpacks the three-fold barriers experienced by women belonging to minorities groups – first, as minority group, second as women and third as minority women. Lack of awareness, perceiving their “present state” as destiny, social and local norms and patriarchal way of thinking force these women to live with identity of secondary citizens.

Published: October 2019

Coir retting yards are concentrated along the southern coastal line and specially women folk, find this work as the source of their principle income for the fisher's family in off season of fishing. However, traditional conventional method of retting has adverse impacts on the ecosystem and human beings. The study was conducted to determine the impact of coir retting on the Socio- Economic Status (SES) and health status of women involved in coir retting in Rathgama are of Galle district. A total of 35 coir retting families were randomly selected and interviewed using a pre-tested structured questionnaire. Data obtained was statistically analyzed by using SPSS Soft-ware. Water quality parameters, such as pH, Temperature, BOD, COD, NO3-N and conductivity were analyzed in coir retting yards. All the water quality parameters were not in permissible ranges. Literacy level in the study population was relatively low; 77 % showed primary education; < 18% and 5 % showed secondary and tertiary education respectively. The average household size and daily net income of the coir retting family involved in the industry were 4.8 and Rs. 275.00 respectively. They earn low income due to lack of proper marketing facilities. Field survey results indicated that 90 % suffer from job oriented diseases like skin disease, blindness, headache, backbone pains and respiratory disease. Retted husk release more organic pollutants and they highly affect the water quality parameters. Therefore, it is a difficult task to protect these women from these occupational hazards. Finally the majority of the families fall within the low SES with deepening poverty background depicted by low educational achievement and occupational status. The results of this study will help to design new techniques as well as providing a good market for these products to improve the income level of the target group.
Notes on the morphology, ecology and distribution of Quisqualis parviflora (Combretaceae)
Authors: Boon Richard G.C.
Published: October 2019

Background: Quisqualis parviflora Gerrard ex. Sond. is endemic to the KwaZulu-Natal and Eastern Cape provinces, South Africa. The species’ distribution has previously been thought to extend to Mpumalanga and the KwaZulu-Natal midlands. Most published distributions include Maputaland in north-eastern KwaZulu-Natal, and it has been suggested that the species may occur in Mozambique. Sterile material of several Combretum Loefl. lianas may be confused with Q. parviflora.Although the species may be locally common, it has never been collected in fruit. Published fruit descriptions are based on erroneously identified material.Objectives: The aim of this study was to supply a revised distribution range, to describe the fruit of Q. parviflora and to present notes on the phenology and ecology of the species.Method: Herbarium specimens of Q. parviflora, and similar taxa, were examined in various herbaria. Fieldwork was undertaken, and other active field botanists were consulted.Results: Quisqualis parviflora is almost entirely restricted to scarp forest between Port St. Johns in the Eastern Cape and Eshowe in KwaZulu-Natal. Although the species may be locally common, it has only been collected from a few localities. The current dispersal ability of the species may be extremely limited, which could have long-term conservation implications.Samaras are described, and notes are provided on the phenology and ecology of the species.Conclusion: Although not currently threatened, the long-term prospects of Q. parviflora may be less secure. Proposed forest management interventions like liana thinning should not be undertaken without more information.

Authors: Wessels Janke , Walsh Corinna M. , Nel Mariette
Published: October 2019

Background: A high prevalence of smoking and alcohol use has been reported in patients with tuberculosis (TB) by several researchers, even though these lifestyle habits have a negative impact on prognosis and treatment.Aim: To determine the smoking habits and alcohol use of patients with TB and TB/human immunodeficiency virus (HIV) co-infection, and how it is associated with gender, level of education and body mass index (BMI).Setting: The study was conducted at Standerton TB Specialised Hospital, Mpumalanga.Methods: A cross-sectional approach was applied. A structured interview was conducted by the researcher with each of the 100 hospitalised patients to obtain information about smoking habits, alcohol use and level of education. Weight and height were measured using standard techniques.Results: Almost six out of 10 participants (58%) indicated that they were former (44%) or current (14%) smokers. Nearly half (49%) reported that they used alcohol, with 25% drinking alcohol more than three times per week. Significantly more women than men were non-smokers (60.0% vs. 30.0%) and more men drank alcohol three times or more per week than women (36.7% vs. 7.5%). Participants who indicated that they were either former or current smokers had significantly lower levels of education than participants who were non-smokers (95% confidence interval [CI] [−26.7%; −2.6%] and [−39.9%; −1.0%] respectively).Conclusion: A high percentage of patients with TB and TB/HIV co-infection previously or currently smoked and used alcohol. Smoking and alcohol use are likely to have a negative impact on nutritional status and may further affect the prognosis of patients with TB.
The Impact of the Great Depression in Ecuador

Published: October 2019

Abstract

This investigation started with an inquiry: did the Great Depression impact Latin America similarly? Does the case of Ecuador represent a point of dissimilarity? Ecuador does represent an atypical case in the region. The data presented in this study shows that the impact of the Great Depression in Latin America was uneven: while the region declined sharply from 1929 to 1932, and since 1933 it registers signs of accelerated growth, Ecuador remained stagnant throughout the decade studied.

However, the development of some macroeconomic data are similar in the entire region because of the close commercial links with the United States of America. The evolution of foreign trade and public finances were similar: a profound reduction until 1932-1933, and then a quick recovery.

Finally, the Great Depression represents a break point in Latin American: the growth of the region passes from depending on the external trade to a development that focused on the ingrowth.

Abstract. Affordable housing was developed in order to give equal opportunity for middle and low-incomers in owning a house, especially in Malaysia. To make sure that these people can have a quality house, the National Housing Policy (DRN) with Pelan Tindakan DRN has been introduced by the Malaysian Government to not only provide adequate housing, but also a comfortable, fun and affordable for the wellbeing of the people in Malaysia (KPKT, 2011). Therefore, sustainability for housing is important to achieve balance between economic development, social interactions and environmental impact by reducing the problems related to population growth, urbanisation, slums, poverty, climate change, lack of access to sustainable energy, and economic uncertainty. One of the goals in DRN and Pelan Tindakan Dasar Perumahan Negara (PTDRN) is to provide an affordable housing and ensure the people from low-income can own a house. However, there is an issue towards assessing the sustainability level of affordable housing, especially in social aspects. This study will discuss on sustainability of affordable housing in Malaysia focused on social aspects. Assessment of spatial indicators was conducted to assess the indicator's implementation of social aspect of the sustainability model. The indicators used in this study include public community facilities, health, safety, religion, and public transportation. These indicators will determine the level of sustainability of the affordable housing. From the results, most of the affordable housing in Malaysia is in intermediate level of sustainability in term of social aspects. These results can help/guide the Government in planning and development in the future, especially with collaboration from private agencies and non-government organization (NGO).

Abstract. Bauchi for the first time in history experienced a horrific windstorm that lasted for not more than 2 hours, but destroyed more than 20 lives and thousands urban infrastructure. This study examines the monumental damage on buildings and structures as a result of the June, 2018 windstorm disaster event in Bauchi. Handheld GPS was used in taking the location information 1662 structures affected by the windstorm. GIS was used in assessing the spatial pattern and as well mapping the extent of the damage. The results of the Average Nearest Neighbor indicate a clustered pattern with the index (ANN ratio) at 0.30 less than 1%. Similarly, the study reveals that most of the affected structures are residential land use with of 91.2% identified as damaged while the least is the recreational land use with only 0.3% structures identified as damaged by the disaster. On a district level, Jahun is the worst affected district with a total of 46.6% damaged buildings and structures. Finally, variability in annual peak wind gust trend in the last decade suggests the evidence of climate change footprints in Bauchi.

Abstract. Map representation of vulnerability is a crucial step in evaluating flood impact and all vulnerability indicators that are the final product of risk assessment. So far, in flood risk assessment, this is probably the weakest link. Flood risk mapping suffers from inequality in the level of development in presenting the different components: where exposure and hazard modelling and mapping is well developed and advanced, while vulnerability analysis and mapping are underdeveloped. Therefore, the objective of this paper is to discuss a newly developed GIS-based approach on micro-scale flood vulnerability mapping of physical elements at risk using an indicator-based method. Micro-scale flood vulnerability is used to eliminate flood vulnerability in an area with a high probability of occurrences. The approach is suitable for cost-benefit analysis of structures protection measures. At micro-scale flood vulnerability mapping, it is more suitable to adopt indicator-based vulnerability assessment methods. Because it provides an opportunity for incorporating all the factors and characteristics of elements at risk that contribute to generating their flood vulnerability. Likewise, a considerable amount of studies argue that vulnerability assessment and its representation on maps should focus on the identification of variables that influence the vulnerability of an element at risk. Flood vulnerability mapping at micro-scale provides critical information for the decision-makers on why specific infrastructures are susceptible more than the others. Moreover, assessing and managing flood risk is crucial in order to reduce the loss and adapt to the combined effects of rapid urbanization and climate changes.

Abstract. Every year, World Bank Group (WBG) is conducting assessment for 190 countries and produces a ranking report based on Doing Business performance – an initiative to measure benchmark efficiency on business regulation and their enforcement by a sample study (e.g. for Malaysia is Kuala Lumpur City Hall - DBKL). One of the ranking categories is based on Dealing with Construction Permits (DCP) which made us proud as announce Malaysia ranks for 2019 is #3 (based on 2018 assessment). This achievement was based on continues efforts and studies from the last bottom of #137 (since, 2007), #113 (2012) and continues with positive results (straight improvement) respectively till this year. Maintaining the top three ranks is not an easy task; however, is not impossible either. Lots of study in innovations, suggestions and implementation should be carried out to maintain and improve Malaysian DCP ranks. As per DCP of this year assessment, Work Bank has suggested all countries with 5 new suggestions (new additional marking schema). One of them is to engage Geographic Information System (GIS) for land use, cadastre, water, electricity and sewage related datasets. This paper propose an initial study (concept paper) towards engaging GIS in DCP activity as a response (first action) suggested by World Bank Group; crucial in maintaining DCP rank for 2020 as well as to provide better business regulations and enforcements for DBKL or other local authority. Later, an impact study will be conducted, utilizing new integrated GIS system publishing service (GeoMap) and the output of the study will indicate whether Malaysia Productive Corporation (MPC) should engage or ignore the 5th suggestion by World Bank Group, or to enhance with other initiatives.

Abstract. When it comes to business and marketing, huge outdoor advertising is considered as one of the best ways by contributing largely in disseminating information about a product, service or even raise awareness. With commuters or the people riding in a moving car as its target audience, the placement of advertising materials is very crucial since it should be visible and must deliver its message in a short span of time. This study tests the methodology of gathering data using action camera and DSLR mounted and situated on a moving vehicle, utilizing structure from motion techniques, to extract the geometry of the billboards from the point cloud generated from structure-from-motion as acquired from camera videos that would be used to represent these billboards in the three-dimensional space. These extracted geometries would be used for visibility analysis from a passenger’s point of view by assessing the percentage of visible content and logos of each billboard from each point of observation along the path of a moving vehicle. The results of this study are nine sets of mean percent visibilities and raster representations that show the mean percent visibility of the billboards as viewed from the road of interest. To assess product placement effectiveness of the billboards, visibility percentage of the product logos contained in the nine billboards was also obtained.

Abstract. This extended abstract presents initial results from a study that focus on the accuracy of satellite-based maps of Accra’s urban expansion as well as their comparability and ability to provide a basis for assessing urban spatial growth dynamics. Within the study we have analysed five different satellite-derived maps of urban development in Accra and compared the results and underlying methods. It is discussed how these maps can be operationalized and, combined with census data and digital road maps, used for calculating how flood events that disable parts of the transport infrastructure impact the overall mobility of the Accra population.

Abstract. In recent years, 3D model for indoor spaces have become highly demanded in the development of technology. Many approaches to 3D visualisation and modelling especially for indoor environment was developed such as laser scanner, photogrammetry, computer vision, image and many more. However, most of the technique relies on the experience of the operator to get the best result. Besides that, the equipment is quite expensive and time-consuming in terms of processing. This paper focuses on the data acquisition and visualisation of a 3D model for an indoor space by using a depth sensor. In this study, EyesMap3D Pro by Ecapture is used to collect 3D data of the indoor spaces. The EyesMap3D Pro depth sensor is able to generate 3D point clouds in high speed and high mobility due to the portability and light weight of the device. However, more attention must be paid on data acquisition, data processing, visualizing, and evaluation of the depth sensor data. Hence, this paper will discuss the data processing from extracting features from 3D point clouds to 3D indoor models. Afterwards, the evaluation on the 3D models is made to ensure the suitability in indoor model and indoor mapping application. In this study, the 3D model was exported to 3D GIS-ready format for displaying and storing more information of the indoor spaces.

Abstract. The smart city concept may aid in improving the city management, enhance the efficiency and thus increase the effectiveness of the city, where it is mainly focused on both information and technologies. This concept appears to be applicable for a smaller area such as university campus. Based on this idea, this research tries to implement the 3D smart campus for Universiti Teknologi Malaysia (UTM). This is an initial research towards a real implementation of 3D smart campus and conceivably 3D smart cities. This research focuses on the development of UTM smart campus by using 3D city modelling. The QGIS software was used to develop the 3D models. Then, the 3D model is viewed in a web browser for better 3D visualization and navigation. Furthermore, the results show that the 3D developed models for UTM smart campus can be a reliable platform to manage the spatial query and viewing the attributes of UTM campus buildings and facilities. This can be seen beneficial to the physical future development of the UTM campus area.
