The Molten Salt Fast Reactor (MSFR) with its liquid circulating fuel and its fast neutron spectrum calls for a new safety approach including technological neutral methodologies and analysis tools adapted to early design phases. In the frame of the Horizon2020 program SAMOFAR (Safety Assessment of the Molten Salt Fast Reactor) a safety approach suitable for Molten Salt Reactors is being developed and applied to the MSFR. After a description of the MSFR reference design, this paper focuses on the identification of the Postulated Initiating Events (PIEs), which is a core part of the global assessment methodology. To fulfil this task, the Functional Failure Mode and Effect Analysis (FFMEA) and the Master Logic Diagram (MLD) are selected and employed separately in order to be as exhaustive as possible in the identification of the initiating events of the system. Finally, an extract of the list of PIEs, selected as the most representative events resulting from the implementation of both methods, is presented to illustrate the methodology and some of the outcomes of the methods are compared in order to highlight symbioses and differences between the MLD and the FFMEA.

Phenotypic variation among clones (individuals with identical genes, i.e. isogenic individuals) has been recognized both theoretically and experimentally. We investigate the effects of phenotypic variation on evolutionary dynamics of a population. In a population, the individuals are assumed to be haploid with two genotypes : one genotype shows phenotypic variation and the other does not. We use an individual-based Moran model in which the individuals reproduce according to their fitness values and die at random. The evolutionary dynamics of an individual-based model is formulated in terms of a master equation and is approximated as the Fokker-Planck equation (FPE) and the coupled non-linear stochastic differential equations (SDEs) with multiplicative noise. We first analyze the deterministic part of the SDEs to obtain the fixed points and determine the stability of each fixed point. We find that there is a discrete phase transition in the population distribution when the probability of reproducing the fitter individual is equal to the critical value determined by the stability of the fixed points. Next, we take demographic stochasticity into account and analyze the FPE by eliminating the fast variable to reduce the coupled two-variable FPE to the single-variable FPE. We derive a quasi-stationary distribution of the reduced FPE and predict the fixation probabilities and the mean fixation times to absorbing states. We also carry out numerical simulations in the form of the Gillespie algorithm and find that the results of simulations are consistent with the analytic predictions.

This research examines Japanese non-native speakers' (JNNS) modal auxiliary verb use from two different perspectives: frequency of use and preferences for modalities. Additionally, error analysis is carried out to identify errors in modal use common among JNNSs. Their modal use is compared to that of English native speakers within a spoken dialogue corpus which is part of the International Corpus Network of Asian Learners' English. Research findings show at a statistically significant level that when compared to native speakers, JNNSs underuse past forms of modals and infrequently convey epistemic modality, indicating the possibility that JNNSs fail to express their opinions or thoughts indirectly when needed or to convey politeness appropriately. Error analysis identifies the following three types of common errors: (1) the use of incorrect tenses of modal verb phrases, (2) the use of inflected verb forms after modals, and (3) the non-use of main verbs after modals. The first type of error is largely because JNNSs do not master how to express past meanings of modals. The second and third types of errors seem to be due to first language transfer into second language acquisition and JNNSs' overgeneralization of the subject-verb agreement rules to modals respectively.

In tunneling projects, a significant part of the costs is spent on segment production. By more economically producing, the cost of tunnel construction can be greatly reduced, especially in long and large-diameter tunnels. In the present study, the effect of using the Carousel method in the improvement of the production system performance compared to the conventional Static system has been studied. To carry out the research, a quantitative comparison of cost and production time was carried out for two production methods using the available documentation. The opinions of experts have been obtained using questionnaires and qualitative comparison of cost, time and production quality was done by implementation of statistical analysis. The SPSS software and the univariate t-test were used to analyze the questionnaires. According to the results of statistical analysis with SPSS, the use of the Carousel method will reduce production time and costs along with increasing manufacturing quality. According to the documentation analysis, the Carousel method reduces the cost of production by almost 30% and leads to a reduction of the production time to approximately 40% of the Static moulds system. The Carousel method has a higher production rate, efficiency, and better performance. Research into quantifying the benefits of Carousel method in the production system performance is very limited. This comparison is based on real information from the under construction Tabriz Metro project. This article can be very helpful in choosing the best production method.

Recently changes in the technological environment of marine transportation and the increase of traffic volume have fostered a revolution in the design and operation of port and also playing a major role in the development of new types of port in Asian. These changes are dynamic and will continue to influence port physical distribution system. The port of Pusan has been hardly able to handle the traffic increases in recent years by expansion increased mechanization and other operational and institutional improvements but, further traffic increases bring about critical congestion and such congestion is an economic cost to the country in terms of cost of physical distribution. This paper treats the development of entirely new port of Pusan and related transportation system by considering the existing or expected need for improved port capacity and services. The western part of GADUK island is selected as the optimum port site through the detailed analysis of the physical requirement and careful consideration of regional development and since the lead time of the national development plan including the port project from initial planning to implementation is considered as long as 7 to 10 years the aggregated master plan for port development is made and implemented in the year of 2012.

This study aims to understand the experiences of highly educated married immigrant women from China, who hold a master's degree or higher, when selecting an elementary school for their children and to explore the significance of that experience. This study included eight participants, all of whom were married immigrant women who had resided in Korea for a minimum of five years. Data was collected through in-depth interviews, which were conducted over approximately one year, from June 2022 to August 2023. The study was approached as a case study. As a result of this study, the similarities between the cases were "choices based on charactercentered education and cultural convergence", "choices for the child's future and career", and "choices influenced by the primary caregiver's use of bilingualism". The differences observed in the cases appeared in "choices based on the balance between global education ideals and economic realities", "choices based on specialized curriculum content", and "choices based on connections to higher-level schools". This study is important, as it underscores the need to conduct various research initiatives on multinational immigrant women and their children. These findings suggest that the study can contribute to the development of multicultural policies that are grounded in the actual experiences and critical awareness of married Chinese immigrant women, who constitute a substantial part of Korean society.

One-hundred eighty four medical doctors and 349 nurses out of 6 university hospitals and 1 general hospital were surveyed from Mar. 3, to Mar. 31, 1995, in order to appreciate the extent of their understandings on the clinical nurse specialist system. The difference was analyzed by the subjects' age, their position and department, the expected benefits of the system. the assigned department, the position and qualification, the required special educational organization and program, and the extent of autonomy of the function of clinical nurse specialists and the special nursing field. The results were as follows ; 1. The perception about the expected benefits of the introduction of clinical nurse specialist system was significantly different among the age groups of medical doctors, and the age group of 40s among them showed the most positive perception. 2. The extent of acquaintance with clinical nurse specialist was the higher in the older age groups of respondent nurses. Meanwhile, the experience of participation with clinical nurse specialists was the more in the older age group of medical doctors. 3. The opinion about the required position of clinical nurse specialists was significantly different by the age and position of the respondent nurses. The rank of head nurse was suggested by the respondent nurses of older age and higher positon, while the level of in-charge nurse was suggested by the staff nurses. Also, the duration of clinical experience required of clinical nurse specialists was the most frequently responded as 6 to 10 years by nurses, as 2 to 5 years by medical doctors. 4. The degree of educational background required of clinical nurse specialists was differently responded by the various position of medical doctors and nurses. Of the medical doctors, professors frequently responded bachelor degree and medical residents frequently responded master degree as the required educational background. Of the nurses, nursing administrators more frequently responded that master degree was required of clinical nurse specialists than staff nurses and clinical nurse specialists did. 5. The extent of acquaintance with clinical nurse specialist system was different among the various department of medical doctors, which was the highest in the doctors of psychiatry, internal medicine and pediatrics, respectively. The doctors of surgery were the least acquainted of clinical nurse specialist. 6. The nurses of special parts, of surgery and of obstetrics & pediatrics responded more frequently that clinical nurse specialists should belong to the nursing department than the nurses of internal medicine and of others did. 7. The Special parts that necessitate clinical nurse specialists were responded to be the more important by nurses than by medical doctors. Clinical nurse specialists were responded to be the more necessary in the parts of diabetics, oncology, pyschiatry, dialysis, organ transplantation, intensive care, and in cardiovascular part. They were responded to be the less important in the parts of intravenous therapy, computer informatics, nursing administration, the improvement of nursing quality.
