This study was conducted to assess the level of satisfaction of undergraduates with the Library and Information Science (LIS) course and some of the factors that influence their choice of the programme. The population of the study was all the 400 level undergraduates in the Department of Library and Information Science, Faculty of Education, University of Port Harcourt. A structured questionnaire, made up of three parts, was utilized for data collection. The first part involved the level of satisfaction of the respondents with the LIS programme while the second and third parts involved the influence of parents and peers on the respondents' choice of LIS programme, respectively. Out of the 21 copies of the questionnaire distributed, 20 were retrieved indicating a 95.2% response rate with 75% (15) male and 25% (5) female. Data were analyzed using percentages and simple regression analysis. Results indicated that the respondents were highly satisfied with the choice of LIS programme and would recommend the programme to others. Parental influence on the respondents' choice of LIS programme was minimal accounting for 7.8% of the changes in the choice of the programme while peer influence on the respondents' choice of the programme was substantial accounting for 78.0% of the changes in the choice of the programme. The fact that the respondents were satisfied with their choice of career in LIS is a strong indication that they would be committed to providing excellent service in librarianship needed to cater for the mutated information requirements of the society.

We consider some dependability management systems(IEC300, NASA AHB5300.1 and DIN VDE 0801) with reference on IEC300. Part I of IEC300(IEC300-1) covers the essential features of a comprehensive dependability programme for the planning, organization, direction, and control of resources to produce products which will be reliable and maintainable. We consider the contents of IEC300-1； scope, normative references, definitions, management responsibilities, product or project independent programme elements and project specific programme elements.

This study was designed to develope an in-service training programme using Interactive $Physics^{TM}$ simulation for science teachers and to evaluate the effect of programme. The purposes of training programme are the improvement of scientific inquiry teaching ability as well as enhancement of the understanding of scientific concepts, inquiry skills, and the computer manipulation skills. The developed programme was implemented four times with 15 hours for each courses. The questionnaire for evaluating the programme after the last course showed that many teachers (1) voluntarily participated in this programme with internal motivation, (2) were satisfied with the level of programme difficulty, professionality of lecturer, and classroom environment, (3) gave positive responses about the achievement of the purposes of this programme, (4) showed strong intention for applying simulation to their school teaching. And future studies were proposed.

Rare-earth (RE) industries generate a massive amount of radioactive residue containing high thorium concentrations. Due to the fact that thorium is considered a non-economic element, large volume of these RE processed residues are commonly disposed of without treatment. It is essential to study an appropriate treatment that could reduce the volume of waste for final disposition. To this end, this research investigates the applicability of carbon-based adsorbent in separating thorium from aqueous phase sulphate is obtained from the cracking and leaching process of solid rare-earth by-product residue. Adsorption of thorium from the aqueous phase sulphate by carbon-based electrodes was investigated through electrosorption experiments conducted at a duration of 180 minutes with a positive potential variable range of +0.2V to +0.6V (vs. Ag/AgCl). Through this research, the specific capacity obtained was equivalent to 1.0 to 5.14 mg-Th/g-Carbon. Furthermore, electrosorption of thorium ions from aqueous phase sulphate is found to be most favorable at a higher positive potential of +0.6V (vs. Ag/AgCl). This study's findings elucidate the removal of thorium from the rare-earth residue by carbon-based electrodes and simultaneously its potential to reduce disposal waste of untreated residue.

Effective management of slightly used nuclear fuel (SUNF) is crucial for both technical and public acceptance reasons. SUNF management, radiotoxicity risk, and associated financial investment and technological capabilities are major concerns in nuclear power production. Reducing the volume of SUNF can simplify its management, and one possible solution is utilizing small modular reactors (SMR) and advanced fuel designs like those with thorium. This research focuses on studying the neutronic performance and radionuclide inventory of three different thorium fuel configurations. The mass of fissile material in thorium-based fuel significantly impacts Kinf, burn-up, and neutron energy spectrum. Compared to uranium, thorium as a fuel produces far fewer transuranic elements and less long-lived fission products (LLFPs) at the end of the core cycle (EOC). However, certain fission product elements produced from thorium-based fuel exhibit higher radioactivity at the beginning of the core cycle (BOC). Physical separation of thorium and uranium in the fuel block, like seed-and-blanket units (SBU) and duplex fuel designs, generate less radioactive waste with lower radioactivity and longer cycle lengths than homogeneous or mixed thorium-uranium fuel. Furthermore, the SBU and duplex feel designs exhibit comparable neutron spectra, leading to negligible differences in SUNF production between the two.

Initial science teacher education in Hong Kong is provided by the Post-graduate Diploma in Education Programme (PGDE) for both pre-service and in-service secondary school teachers. This programme includes a balanced treatment of subject curriculum and teaching in science, general pedagogical knowledge and skills, educational psychology and school administration. The science courses in this programme also have some units that equip science teachers with the knowledge and skills that are essential for teaching a science curriculum that emphasises conceptual change and understanding of the nature and methods of science. This emphasis is illustrated by two studies: (1) Developing a conceptual change model of instruction in Biology teachers, and (2) Constructing understanding of the nature and methods of science.

The purpose of this study is to analyze students' learning characteristics regarding spatial ability, orienteering ability and earth science content learning ability and their relationship through development and application of earth science activities using orienteering. The programme aims to improve students' spatial ability using orienteering activity which requires spatial ability. Topics in the programme included map, compass, contour, movement of celestial, and constellation application. Students were to orienteer in the field using the method they learned in class. This programme was applied to five 7th graders. The results are, first, students who have positive attitude toward science and do well at school tended to perceive their orienteering ability high. Second, all parts of spatial ability, spatial visualization, spatial orientation, spatial relation were used during orienteering, especially spatial visualization and spatial orientation. The relationship between spatial ability, orienteering ability, and earth science content learning abilities was not clear. However, orienteering ability and earth science content learning ability were in similar tendency.
