Myanmar has experienced many types of geologic hazards such as earthquakes and landslides and to a lesser extent, subsidence. In recent years, landslides have been a major form natural disaster in Myanmar, especially in the country’s mountainous regions, such as Chin State. In geomorphological terms, Myanmar has two mountainous regions: namely the Western Ranges and the Eastern Highlands. Steep slopes, unstable geologic conditions, and heavy monsoon rains make these regions the most landslide-prone areas in Myanmar. The study area, Hakha City and its environs, is situated in Chin State, which occupies a part of the Western Ranges. Chin State suffers many landslide incidents each year. Human settlement has recently increased as a result of rapid population growth. Consequently, natural and man-made disasters are on the rise and affecting people more than before. The most devastating landslide on record in Myanmar occurred in July 2015 due to the impact of Cyclone Koman. After this landslide, some places of Hakha City resettled in new location. However, a detailed slope stability analysis and assessment of the new location have not yet been carried out. In addition, management procedures and systems for the relocation and resettlement process still need to be evaluated for the urban safety space. Existing research and papers focus mainly on the areas affected by the landslide rather than on the city’s new location based on geographic information system (GIS) tools. It is essential to study the potential risk of landslides in the new location properly, and identify an appropriate management system. Geological conditions including highly weathered and crushed rocks, heavy rainfall intensity, and poor drainage systems combine slope stability. Systematic management programs and technical control methods can mitigate the number and magnitude of future disasters.

Abstract Localised landslide activity has been observed in the area of the plateau slope analysed, in the vicinity of the planned Warsaw Southern Ring Road. Using calculation models quantitative and qualitative evaluations of the impact of natural and anthropogenic load factors on slope stability (and hence, safety) are made. The present paper defines six stages of slope stability analysis, leading to an indication of optimum slope design in relation to the development planned. The proposed procedure produces a ranking of factors that affect slope stability. In the engineering geological conditions under consideration, the greatest factors impacting degradation and failure of slope stability are changes in soil strength due to local, periodic yielding and the presence of dynamic loads generated by intensification of road traffic. Calculation models were used to assess the impact of destabilisation factors and to obtain mutual equivalence with 3D-visualisation relations. Based on this methodology, various scenarios dedicated to specific engineering geological conditions can be developed and rapid stability evaluations of changing slope loads can be performed.

The Impact

Reliability of equilibrium state evaluation about settlement slopes in the context of natural and human-made hazards is a complex issue. The geological structure of the vicinity of the upland slope in the urban environment of Warsaw is characterised by a significant spatial diversification of the layers. This is especially due to the glacitectonics in the Mio-Pliocene clays, which are located shallowly under the sandy tills’ formations. With substantial variability in the clay roof surface, point recognition by drilling is often insufficient. The use of electrical resistivity imaging (ERI) in the quasi-3D variant provides accurate images of the real ground conditions, which is crucial in optimal geotechnical design. In forecasting the behaviour of the slope, it is necessary to quantify the impact of spatially differentiated systems of disturbed layers on changes in the safety factor (SF), which corresponds to the observed landslide activity of the Warsaw Slope. This study concerns numerous calculation model analyses of the optional clay position in the context of slope stability conditions. A wide range of soil properties variability was taken into account, resulting from both lithogenesis and subsequent processes disintegrating the original soil structure. Regarding the geological conditions of the slip surface, the use of classical computational methods and numerical modelling (FEM) was considered for comparative purposes. The results indicated that local changes in equilibrium conditions were affected by the different morphology of the clay roof surface of the slope and the alternation in strength characteristics on the slip surfaces. The findings of the study contribute to sustainable spatial planning of near-slope regions.

Abstract This paper presents the impact of selected essential aspects of geological structure on the state of slope stability as assessed by changes in the safety factor (SF). The engineering geological slope features that were analysed include: (i) changes in soil cohesion and internal friction angle, (ii) presence of a weak soil layer and its span, (iii) structural discontinuity (i.e. fault), (iv) soil permeability properties and water conditions (i.e. groundwater level, long and heavy rainfall). A certain scheme of slope stability calculations has been proposed for a case involving complex geological conditions. The numerical modelling of a hypothetic slope was performed using the shear strength reduction method based on the finite element method.

AbstractIntroductionThe catastrophic Great East Japan Earthquake in 2011 created a crisis in a university-affiliated hospital by disrupting the water supply for 10 days. In response, this study was conducted to analyze water use and prioritize water consumption in each department of the hospital by applying a business impact analysis (BIA). Identifying the minimum amount of water necessary for continuing operations during a disaster was an additional goal.ProblemWater is essential for many hospital operations and disaster-ready policies must be in place for the safety and continued care of patients.MethodsA team of doctors, nurses, and office workers in the hospital devised a BIA questionnaire to examine all operations using water. The questionnaire included department name, operation name, suggested substitutes for water, and the estimated daily amount of water consumption. Operations were placed in one of three ranks (S, A, or B) depending on the impact on patients and the need for operational continuity. Recovery time objective (RTO), which is equivalent to the maximum tolerable period of disruption, was determined. Furthermore, the actual use of water and the efficiency of substitute methods, practiced during the water-disrupted periods, were verified in each operation.ResultsThere were 24 activities using water in eight departments, and the estimated water consumption in the hospital was 326 (SD = 17) m3per day: 64 (SD = 3) m3for S (20%), 167 (SD = 8) m3for A (51%), and 95 (SD = 5) m3for B operations (29%). During the disruption, the hospital had about 520 m3of available water. When the RTO was set to four days, the amount of water available would have been 130 m3per day. During the crisis, 81% of the substitute methods were used for the S and A operations.ConclusionThis is the first study to identify and prioritize hospital operations necessary for the efficient continuation of medical treatment during suspension of the water supply by applying a BIA. Understanding the priority of operations and the minimum daily water requirement for each operation is important for a hospital in the event of an unexpected adverse situation, such as a major disaster.SuginakaH,OkamotoK,HiranoY,FukumotoY,MorikawaM,OodeY,SumiY,InoueY,MatsudaS,TanakaH.Hospital disaster response using business impact analysis.Prehosp Disaster Med.2014;29(5):1-8.

The Impact

In the current era of urban development, people are already using electric vehicles more and more often for transport purposes, which reduces negative impacts on the environment. However, there are still vehicles in towns and cities that run on ordinary internal combustion engines. Performing optimization measures on the operation of these vehicles improves their performance, which can result in positive sustainable development effects. This article presents measures to reduce the wear and tear of urban vehicles and outlines a decision model to determine which of the vehicle parts described suffer the most frequent wear and tear under urban conditions. The article presents a list of structural elements that are most affected by urban traffic, as well as corrective actions to improve such specialized vehicles. Based on the decision analysis, Rule 1 was eliminated as having the least significant impact on vehicle wear and tear, and the least significant impact on urban safety. On the other hand, the most worn-out elements were found to be gearboxes, clutches, bus levelling electronics, and brake pads and discs. The decision-making model made it possible to identify the factors which have the greatest impact on reducing safety in urban spaces.

Abstract: This research discusses the process of forming and developing of Pondol village in Manado as a location for exile along with the Dutch colonial government policy that placed exiles who came from several sultanates in Java in the Manado Residency during the 19th century. The discussion includes, first, the background of the exile of the Javanese aristocrats in Manado. Second, the process of establishing Pondol as a location for exile and its development during the XIX century, and third, the adaptations made by the exiles to adjust to their exile and the impact of their arrival on the Manado-Minahasa community. The historical method is used in this research, using colonial archives from the XIX century which are stored in the National Archives of the Republic of Indonesia, and local sources, especially manuscripts stored by their descendants in Manado and Java. The findings in this study are; Kampung Pondol was formed due to the isolation of Kanjeng Ratu Sekar Kedaton and Pangeran Suryeng Ingalaga and some of his followers originated from political intrigue that occurred in the Sultanate of Yogyakarta. Second, the reason why Kampung Pondol was chosen as the new location for exile by the Dutch colonial government for Javanese royal officials was different from the exile of other figures in Tondano and Tomohon. Third, the form of adaptation carried out by the exiles in Kampung Pondol Manado was marriage with women from Manado and relationships with Dutch people who lived around them.Keywords : Exile, Javanese Noble, Pondol Village, Adaptation. Abstrak: Penelitian ini membahas tentang proses terbentuk dan perkembangan kampung Pondol di Manado sebagai lokasi pengasingan seiring dengan kebijakan pemerintah kolonial Belanda yang menempatkan para eksil yang berasal dari beberapa kesultanan di Jawa di Karesidenan Manado pada sepanjang abad 19.  Pembahasannya meliputi; Pertama, Latar belakang pengasingan para bangsawan Jawa di Manado. Kedua, proses terbentuknya Pondol sebagai lokasi pengasingan dan perkembangannya selama abad XIX, dan Ketiga, adaptasi yang dilakukan para eksil untuk menyesuaikan diri di pengasingan serta dampak kedatangan mereka pada masyarakat Manado-Minahasa. Metode sejarah dipergunakan dalam penelitian ini, dengan mempergunakan sumber Arsip Kolonial kurun waktu abad ke XIX yang tersimpan di Arsip Nasional Republik Indonesia,  dan sumber lokal terutama manuskrip yang tersimpan oleh keturunannya di Manado dan Jawa. Temuan dalam penelitian ini adalah; Kampung Pondol terbentuk karena Pengasingan Kanjeng Ratu Sekar Kedaton dan Pangeran Suryeng ingalaga dan beberapa pengikutnya berawal dari intrik politik yang terjadi di Kesultanan Yogyakarta. Kedua, alasan Kampung Pondol dipilih sebagai lokasi baru pengasingan Pemerintah Kolonial Belanda bagi pembesar kerajaan Jawa yang berbeda lokasi dengan pengasingan tokoh-tokoh lainnya di Tondano dan Tomohon. Ketiga, bentuk adaptasi yang dilakukan oleh para eksil di Kampung Pondol Manado dilakukan pernikahan dengan wanita dari Manado dan relasi dengan orang-orang Belanda yang tinggal disekeliling mereka.Kata Kunci : Eksil, Bangsawan Jawa, Kampung Pondol, Adaptasi.

Purpose The purpose of this paper is to reveal the importance of the order of establishment of temporary logistics hubs (TLHs) when resources (mobile storage units used as TLHs) are limited and to present the development and implementation of a methodology that determines the order of establishment of TLHs to support post-disaster decision making. Design/methodology/approach It employed a decision support system that considers multiple decision makers and subjective attributes, while also addressing the impreciseness inherent in post-disaster decision making for ordering the establishment of TLHs. To do so, an optimization model was combined with a fuzzy multi-attribute group decision making approach. A numerical illustration was performed using data from the April 2015 Nepal Earthquake. Findings The results showed the location and order of establishment of TLHs, and demonstrated the impact of decision makers’ opinions on the overall ordering. Research limitations/implications The study does not discuss the uncertain nature of the location problem and the potential need for relocation of TLHs. Practical implications This methodology offers managerial insights for post-disaster decision making when resources are limited and their effective utilization is vital. The results highlight the importance of considering the opinions of multiple actors/decision makers to enable coordination and avoid complication between the growing numbers of humanitarian responders during disaster response. Originality/value This study introduces the concept of the order of establishment of TLHs and demonstrates its importance when resources are limited. It develops and implements a methodology determining the order of establishment of TLHs to support post-disaster decision making.
