  • Background: Learning from incidents for accident prevention is a two-stage process, involving the investigation of past accidents to identify the causal factors, followed by the identification and implementation of remedial measures to address the identified causal factors. The focus of past research has been on the identification of causal factors, with limited focus on the identification and implementation of remedial measures. This research begins to contribute to this gap. The motivation for the research is twofold. First, previous analyses show the recurring nature of accidents within the Ghanaian mining industry, and the causal factors also remain the same. This raises questions on the nature and effectiveness of remedial measures identified to address the causes of past accidents. Secondly, without identifying and implementing remedial measures, the full benefits of accident investigations will not be achieved. Hence, this study aims to assess the nature of remedial measures proposed to address investigation causal factors. Method: The study adopted SMARTER from business studies with the addition of HMW (H - Hierarchical, M - Mapping, and W - Weighting of causal factors) to analyse the recommendations from 500 individual investigation reports across seven different mines in Ghana. Results: The individual and the work environment (79%) were mostly the focused during the search for causes, with limited focus on organisational factors (21%). Forty eight percentage of the recommendations were administrative, focussing on fixing the problem in the immediate affected area or department of the victim(s). Most recommendations (70.4%) were support activities that only enhance the effectiveness of control but do not prevent/mitigate the failure directly. Across all the mines, there was no focus on evaluating the performance of remedial measures after their implementation. Conclusion: Identifying sharp-end causes leads to proposing weak recommendations which fail to address latent organisational conditions. The study proposed a guide for effective planning and implementation of remedial actions.

  • The aim of this study was to examine the effects of remedial instruction on self-efficacy improvement in elementary school students with low self-efficacy, which may have been formed through negative experience with learning such as poor performance and poor grades. Nine 6th grade students with low self-efficacy were selected for the present study. A remedial class was set up and instruction was given once a week for 14 weeks. The purpose of the remedial class was to give the students a positive experience with English learning and have students reflect on their achievement. The contents and class activities were adjusted to the subjects' English abilities and also closely related to those of the regular classes so that students could have more confidence during regular English classes. The data were collected from a test of self-efficacy in English learning, achievement tests given before and after the experiment, achievement tests after each lesson, a general self-efficacy test, a basic questionnaire, interviews, journals, and students' self-evaluation. The results showed that the remedial instruction was very successful in providing students with a sense of achievement and improving students' self-efficacy in English learning. However, this study failed to find significant improvement in general self-efficacy tests and achievement tests given before and after the experiments. A longer period of remedial instruction may have been necessary to obtain more concrete results from the variety of data collected.

  • Distressed structures require necessary remedial measures in order to restore their original structural properties like strength and stiffness. Validating the effectiveness of the proposed qualitative remedial measure experimentally is of utmost importance as there is no well-established analytical method to verify the effectiveness of the same quantitatively. Prototype testing which would have been the best option for this purpose would not only prove costly but also be associated with numerous practical difficulties; hence model testing is resorted as the only option for the purpose. This paper presents one such typical experimental study on the structural behavior of a distressed bridge, mainly observed in the form of prominent tilt in the bearing plate in transverse and longitudinal direction on downstream side. The main focus of the proposed experimental investigation is to assess the structural behavior particularly the load carrying capacity. The extent of deformation of some models with specific structural arrangements and some models with specific need based remedial measures were also studied. This study also assessed the contribution of each remedial measure towards restoration individually and collectively.

  • It is undeniably important to bring up a solution capability of arithmetic word problems in the elementary mathematical education. The goal of this study is to acquire the implication for remedial instruction on arithmetic word problems solving through surveying elementary school students' difficulties in the solving of arithmetic word problems. In order to do it, this study was intended to analyze the following two aspects. First, it was analyzed that they generally felt more difficulties in which field among addition, subtraction, multiplication and division word problems. Second, with the result of the first analysis, it was examined that they solved it by imagining as which sphere of the other word problems. Also, the cause of their error on the word problem solving was analyzed by the interview. From the foregoing analyses, the following implications for remedial instruction on arithmetic word problems solving are acquired. First, the accumulation of learning deficiency must be diminished through the remedial instruction. Second, it must help students to understand the given problem and to make of what the goal of problem is. Third, it must help students to form a good habit for reading the problem and to understand the context of problem. forth, the teacher must help students to review and reflect their problem-solving processes.

  • ISO(Independent System Operator) or TSO(Transmission System Operator) use power system analysis program to simulate contingency analysis and remedial actions to operate power system stably. Generally, power system analysis program provides automated analysis functions(or modules) to deal with wide area power system. However, because of missed contingency cases, automated contingency analysis has no practical use or has limitation. And in case of remedial action, it doesn't support automated function or takes a lot of times to study, because of simulation in manual for each cases. This paper suggests that new relation with buses and transmission line properties of power system DB used for power system analysis program to simulate automated contingency including all contingency cases needed in the field without missed cases. And it proposes automated remedial action scheme based on practical approach analysis to alleviate overloading or voltage problems. Finally it deals with automated contingency/remedial action analysis(automated scheduled outage) program which is developed by KEPCO and its performance and proposed schemes are proven by case study for real Korean power system data.

  • The mathematical ability is an essential element for achieving professional competencies and for enhancing application ability in a vocational world and exploring its experiences. In this aspect, for vocational high school students, it is an important and urgent issue to develop remedial learning programs for developing mathematical basic and application ability. In particular, the program is developed based on the individual achievement level, focused on a mathematical basic ability to be applied efficiently in a vocational world. Because of this reason, in this study, the program is comprised of two phases; one is diagnosis test and the other is remedial teaching and learning materials. Then, diagnosis test includes three test; I) level testing evaluation for selecting the subject of remedial learning, ii) pre-test for deciding on which area and level of the materials when students begin to study, and iii) post-test for confirming the learning status is satisfied and the possibility of next step(level) or the other area of the materials. To accomplish this, this study tried to devise an efficient remedial learning system. Based on the system, this study developed remedial learning programs on the four areas of number and quantity, change and relation, uncertain thing, and figure and shape in the middle school level. In particular, this program is comprised of two types of knowledge. One is K-knowledge which is an essential knowledge to achieve a basic mathematical ability. The other is C-knowledge which is the advanced knowledge required to apply efficiently in a vocational world. This paper deals with the content mentioned above, but examples of the materials is shown focused on the area of change and relation.

  • The aim of this research is to survey the census of street trees and to provide remedial measures for street trees management to Miryang City. To do this, survey was carried out 16 region units in Miryang City. Through the survey, the current status of street trees’ map was made using automated map. From the results, it is turned out that 17,079 trees have been planted in Miryang City. The major species of street trees are Prunus serrulata var. spontanea(41.6%), Ginkgo biloba(26.1%), Pinus thunbergiana(13.3%) and the others are 12 species(19.0%). By the region units, Samrangjin-Eub is the most that 2,308 street trees are planted, and the next is Chodong-Myon(2,206 trees). The littlest street trees planted region is Cheongdo-Myon. In the results of comparison the component of street trees with other municipal cities, e.g. Seoul, Incheon, Kwangyang etc., only a few street trees have been planted so many in Miryang City. So, Miryang City indicated high proportionate street trees planting ratio. The suggested remedial measures are consisted with identifying the each street, increasing the green area by accepting the suitable street tree planting model, improving the physiological growth condition and systematic management with GIS.

  • This study was conducted to investigated the feasibility of using a fused borate rod for the remedial treatment, using pine specimens decayed by Tyromyces palustris and Gloeophyllum trabeum. The borate rod appears to be a useful remedial product for eliminating as well as preventing decay. However, the easiness of retention gradient of boron according to the distance from a rod treatment site, is required for more effective treatment. The effect of the extension of diffusion period and rod size on retention gradient of boron should be fully investigated for successful remedial treatments using borate rod.
