Many earthquakes in the past had shown that major damage to structures took place in the absence of proper design, construction, and quality control. Based on the extent of damages caused by earlier earthquakes and the building vulnerability parameters that has caused the damages, a statistical analysis was carried out to develop a vulnerability score sheet. In this score sheet, a vulnerability score is computed considering building attributes such as soft storey, substantial overhang, re-entrant corners, the age of buildings, apparent material and construction quality, eccentric staircase location with respect to building plan, maintenance, soil type and a number of storeys. This score sheet will be a very helpful technique for assessing huge building stocks.

Vulnerability Score

Abstract Rapid Visual Screening (RVS) method for buildings was originally developed by the Applied Technology Council (ATC) in the late 1980’s for potential seismic hazards. This is a simple and almost a quick way of assessing the building seismic vulnerability score based on visual screening. The logarithmic relationship between final score and the probability of collapse at the maximum considered earthquake (MCE) makes results somewhat difficult to interpret, especially for less technical users. This study is developed to improve the simplicity and usefulness of RVS methodology to determine the numeric scores for seismic vulnerability of buildings using vulnerability functional form. The proposed approach applies the existing method in FEMA 154 (2002) for calculating the building rank based on RVS method. In this study RVS scores are used to evaluate populations of buildings to prioritize detailed evaluations and seismic retrofits. The alternate non-logarithmic format of scoring scheme is much better meeting the needs of the project managers and decision makers, as they require results that are easier to understand. It shows the linear equivalent of RVS final scores which is consistent with the existing ranking systems used in the buildings management program such as budget allocation decision making. The results demonstrate that the weight determined for the factor of “Region Seismicity”, which is 0.4033, has the highest contribution to seismic vulnerability scores of buildings. The applicability of the proposed method is demonstrated through a hypothetical example to rank ten seismically vulnerable buildings.

Rapid visual screening is a quick and simple approach often used by researchers to estimate the seismic vulnerability of buildings in an area. In this study, preliminary seismic vulnerability assessment of 500 buildings situated at Northern and Eastern George Town, Malaysia, was carried out by utilizing a modified FEMA-154 (2002) method that suits Malaysian conditions. Data were collected from online sources via Google Maps and Google Earth instead of traditional surveying data collection through street screening. The seismic assessment analysis of this study was based on the RVS performance score and the damage state classification for each building typology. This approach generates, for each building, a final performance score based on governing parameters such as structural resisting system, height, structural irregularities, building age, and soil type. The findings revealed the immediate need for effective seismic mitigation strategies, as 90% of the studied buildings required a further detailed analyses to pinpoint their exact seismic vulnerability performance. Most of the surveyed buildings were predicted to experience moderate-to-substantial damage, with 220 out of 500 being classed as damage state 2 (D2) and damage state 3 (D3). A GIS map, “RVS Malaysian Form-George Town Area”, was generated via ArcGIS and shared with the public to provide vital information for further research.

Indonesia is one of the countries prone to earthquakes. One of the earthquake disasters that occurred several years ago hit Palu and Donggala on September 28, 2018. It caused severe damage to infrastructure. Therefore, it is necessary to evaluate buildings vulnerable to earthquakes as a form of prevention. One of the buildings in Jember, the dr. Soebandi hospital, experienced cracks in the walls during an earthquake measuring 6.0 on the Richter scale in Nusa Dua Bali on July 16, 2019. This study carried out the risk assessment of the vulnerability of buildings to earthquakes using the Rapid Visual Screening (RVS) method from FEMA P-154. RVS is a method to identify a building that is potentially vulnerable to earthquake hazards based on visual observations from the exterior and interior of the building. The results of the evaluation using the RVS method showed that the dr. Soebandi hospital is categorized as safe and not prone to earthquakes, with a potential vulnerability percentage of 0.0126%. Based on these results, the building does not require special treatment to anticipate earthquakes; however, maintaining the occupants' safety and extending the building's life requires routine maintenance.

AbstractTeaching an established surgeon in a novel technique by a colleague who has acquired a level of expertise is often referred to as “proctoring” or “precepting.” Surgical preceptorships can be defined as supervised teaching programs, whereby individual or groups of surgeons (proctors) experienced in a certain technique support a colleague who wants to adopt this technique (sometimes referred to as “delegates” or “preceptees”). Preceptorship programs really focus on a specific technique, technology, or skill which is required to broaden, complement, or transform an established surgeon's practice.Within colorectal surgery, in the past 30 years, there is been an evolution of interventional options including open, laparoscopic, robotic, and endoscopic procedures. With each new emerging technology and technique, safe and effective uptake by established surgeons is best been attained by a period of proctorship by an experienced colleague. Formalizing this has been facilitated largely through industry support. There, however, remains a considerable chasm when it comes to standardization, quality control, and jurisprudence.This article aims to describe the requirements for a contemporary proctorship program, to examine instruments of quality control, and how to improve effectiveness.

Since the 18th century, Classification Societies have served the public interest by promoting the security of life, property, and the natural environment. This has been accomplished primarily through the development and verification of standards for the design, construction, and maintenance of marine facilities, however, new insights gained over the past decade have motivated maritime safety organizations to better address the contribution of the human element to maritime casualties and accidents.
