Simulated moving bed (SMB) process is a continuous chromatographic technology used to separate a large amount of petrochemicals, fine chemicals, pharmaceuticals, and so on, drawing a great attraction of related industries. With the recent development of biotechnology, the SMB process has been adopted for the separation of various useful bio-products. Attempts to understand the separation mechanism of the SMB process in many aspects are reported in many publications. These researches have dealt with the improvement of SMB for easier operation and solving problem in process. The feed mixture fed into the SMB process may be of different concentration batch by batch rather than in uniform concentration. Retention behaviors of feed (psicose (A) and fructose (B) mixture) existing in the SMB unit in dynamic steady-state and feed (psicose (C) and fructose (D) mixture) newly injected into the SMB were analyzed. It was observed that the existing components, (A) and (B), were eluted relatively faster as the injection time of new feed was earlier during the port-switching period. In addition, the components (C) and (D) were eluted earlier as fresh feed was injected earlier in a port-switching time.

The goal of this study was to analyze the demands of parents of an after-school program. In order to do this, we looked at cultural centers and their curriculums. Cultural centers are one of the most popular private education centers for preschoolers, and are used for the operation of special activities. The research was conducted on preschool curriculums of 300 cultural centers, including cultural centers of department stores and supermarkets. The curriculum analysis was conducted for 400 preschool curriculums of three cultural centers, which had the most programs of all. The scope of the curriculum analysis was based on the 3rd Childcare Standard Curriculum for infants and Nuri Curriculum for preschoolers. As a result of the analysis, there were 12,286 programs for infants. The most popular topics for programs were comprehensive activity, physical activity, and music activity. There were 15,310 programs for preschoolers. Physical activity was the most popular topic among them. It was followed by drawing activity and number and operating activity. Analyzing the contents of these programs, we found that 'participating in physical activity' of physical exercise, and 'expressing artistically' of artistic experience were the most popular contents of infants. 'Expressing artistically' of artistic experience and 'control of body and basic exercise' of physical exercise were most popular contents for preschoolers. The results show that parents demand physical activity programs for infants and artistic activity programs for preschoolers. The results of the research should be considered when childcare centers try to make a special after-school program.

This paper provides an in-depth examination of the relationship between cinema and Giorgio Agamben's aesthetics and philosophy. Intersecting Agamben's key concepts including gesture, mediality, biopolitics, historicity, and profanation with historical and aesthetic dimensions of cinema, I argue for his ambivalent view on cinema and visual media. On the one hand, Agamben linked cinema and visual media to his discussion on biopolitics and spectacle as he considered them as apparatus for capturing and controlling gestures. On the other hand, he also argued that cinema could restore the image with capacity to preserve and recuperate gestures based on his consideration of montage as cinema's key aesthetic and technical component (an operation of profanation) and his Benjaminian thought on the ways in which montage suspended linear flow of images and activated an alternative memory of them. Drawing on history of cinema and optical devices in the 19th and early 20th centuries as well as examples of found footages of filmmaking predicated upon stoppage and repetition of images, I argue that Agamben's concept of potentialities can be extended into his thought on cinema and visual media apparatuses in general.

As the development of ICT has made it easier to collect various traffic information, research on creating new traffic attributes is drawing attention. Estimation and forecasts of demand and traffic volume are one of the main indicators that are essential to traffic operation, assuming that the traffic pattern at a particular node or link is repeated. Traditionally, a survey method was used to demonstrate this similarity on trip behavior. However, the method was limited to achieving high accuracy with high costs and responses that relied on the respondents' memory. Recently, as traffic data has become easier to gather through ETC system, smart card, studies are performed to identify the regularity of trip in various ways. In, this study, route-level trip data collected in Daegu metropolitan city were analyzed to confirm that individual traveler forms a spatially similar trip chain over several days. For this purpose, we newly define the concept of spatial trip regularity and assess the spatial difference between daily trip chains using the sequence alignment algorithm, Dynamic Time Warping. In addition, we will discuss the applications as the indicators of fixed traffic demand and transportation services.

Currently, there are cases in Korea where economic damage has occurred due to the ambiguity instrument installation and operation standards in the construction of temporary earth retaining wall, failing to prevent collapse of temporary earth retaining wall at the construction site in advance. Therefore, in this study, a numerical analysis was conducted to find the appropriate installation location of the inclinometer and strain gauge among the installed instruments shown in the design drawing of the temporary earth retaining wall. As a results, It was found that the installation position of the underground inclinometer is the corner of the retaining wall in the case of plane-deformation analysis, and the most displacement occurs in the center of the excavation surface in the case of 3D analysis. When the stress and moment are comprehensively analyzed, the corner is judged to be a vulnerable point. In the case of the strain gauge, In plane-deformation analysis and 3D analysis, the maximum bending stress occurred at the wale connection where the end of the strut and the counter strut are in contact. At this point, it is analyzed that it is necessary to focus on installing and managing the connection to prevent accidents from being vulnerable.

Drawing on the deep experience and understanding of the principles of nuclear safety, as well as many years of nuclear power plant design and operation, the EDF led NUWARD SMR Project is developing a design for a Small Modular Reactor (SMR) of 340 MWe composed of two 170 MWe independent units, that will supplement the offering of high-output nuclear reactors, especially in response to specific needs such as replacement of fossil-fuelled power plants. NUWARD SMR is a mix of proven and innovative design features that will make it more commercially competitive, while integrating safety features that comply with the highest international standards. Following the principles of redundancy and diversity and rigorous application of Defence in Depth (DID), with an international view on nuclear safety licensing, the Project also incorporates new safety approaches into its design development. The NUWARD SMR Project has been in development for a number of years, it entered conceptual design formally in mid-2019 and entered Basic Design in 2023. The objective of the concept design phase was to confirm the project technological choices and to define the first design configuration of the NUWARD SMR product, to document it, in order to launch pre-licensing with the French Safety Authority (ASN) and to define its estimated cost and its subsequent development and construction schedules. As a delivery milestone the Safety Options file (called the Dossier d'Options de Sûreté (DOS)) has been submitted to ASN in July 2023 for their opinion. An integral part of the NUWARD SMR Project, is not only to deliver a design suitable for France and to satisfy French regulation, but to develop a product suitable and indeed desirable, for the international market, with a first focus in Europe. In order to achieve its objectives and realise its market potential, the NUWARD SMR Project needs to define and realise its safety approach within an international environment and that is the key subject of this paper. The following paper: • Summarises the foundation principles and technological background which underpin the design; • Contextualises the key design features with regard to the international safety regulatory framework with particular emphasis on innovative passive safety aspects; • Illustrates the Project activities in preparation for first licensing in France, and also a wider international view via the ASN led Joint Early Review of the NUWARD SMR design, including Finnish and Czech Republic regulators, recently joined by the Swedish, Polish and Dutch regulators; • Articulates the collaborative approach to design development from involvement with the Project partners (the Commissariat à l'énergie atomique et aux énergies alternatives (CEA), Naval Group, TechnicAtome, Framatome and Tractebel) to the establishment of the International NUWARD Advisory Board (INAB), to gain greater international insight and advice; • Concludes with the focus on next steps into detailed design development, standardisation of the design and its simplification to enhance its commercial competitiveness in a context of further harmonisation of the nuclear safety and licensing requirements and aspirations.

This is a survey of the reserved book system in the pilot universities in Korea. We have surveyed only 22 university libraries among 29 pilot schools as of 1977, because of the differences in the library users, library organization, library facilities, and library materials between universities and colleges. In 1972, the Korean Ministry of Education developed a reformation plan for their higher education based on the teaching method of curriculum-oriented faculty instead of that of the faculty-oriented curriculum. The former puts emphasis on the cultivation of a student's thinking, creativity, and judgement through self-teaching to do a given assignment. The reserved book system in a college or university library is one of the most important methods necessary to accomplish the above educational aim. The survey used a questionnaire with 50 question on 28 items concerning the various aspects of the reserved book system in 22 pilot universities. the survey result discovered many problems needing correction. The following list describes the measures needed to correct the problems found in the pilot universities. 1. The management of a centralized reserved book system is much more effective and economical than the decentralized reserved book system when a university is located on the same campus. 2. In the university library, an independent reserved book department requires to gain the desired educational aims as compared with the reserved book room controlled by any other department in the library. 3. The reserved book system should not be adopted by all the departments at once but enlarged gradually, for it needs the understanding and support of faculty members and the university itself. 4. As competence is essential to the effective operation of the reserved book room, the university library should not place an unqualified person in charge of the reserved book department. 5. The librarian in charge of the reserved book department is required to do more professional works such as analysis of users, collection and analysis of syllabuses, maintenance of faculty member cooperation, establishment of measures to acquire unavailable materials, and drawing up an effective management plan. However, he is spending most of his time in clerical works, that is, non-professional works. 6. Three to five titles of each reserved book are considered reasonable and required materials should be shelved in proportion to the number of students, that is, one copy per eight or ten students if the materials are allowed to lend for two hours at a time. For the supplementary materials, the library needs to place two or three copies per subject. 7. Professors must select reserved books with care so that they can be used year after year. 8. Few universities are asking professors the number of class students and the date when the reserved material will no longer be needed on reserve. 9. The library should gather all the lists of reserved books from every professor at least three to five months before the courses open, because it takes a long time to obtain foreign materials. 10. It is desirable that the reserved book department should collect the lists and prepare the materials with promptness and consistency. 11. Instead of block buying, it is desirable to purchase reserved books at the time the library gets the reserved book list from the professors. The library should also inform faculty members whether it obtained each reserved book or not before the course open. 12. The library should make a copy of materials if a professor requires to reserve an out-of-print book or partial contents of a book, journal, and thesis. 13. An independent budger for reserved books from the budget for general materials is desired. 14. The shelf arrangement of reserved books by courses or professors under the same department is much more preferable than a classified arrangement. 15. While most of the universities adopted the open shelves system for all the reserved books, it is more effective and economical to take a compromise system, that is, closed shelves for requires materials and open shelves for supplementary materials. 18. Circulation of reserved books needs a different system between required materials and supplementary materials: two or three hours and/or overnight loan for the former and two and/or three days loan for the latter. 17. A reserved book room should be open a long time after class so that students can have sufficient time to use the room. 18. The library must take daily and monthly statistic as well as statistics on every aspect of the reserved book system in order that the library ma decide on policy and management of the reserved book room in collaboration with the university. Furthermore, regular reports on the use of the reserved book room should be made to the president and the executive council by the library to acquire their understanding and cooperation for the reserved book system. 19. Cooperation of faculty members is indispensable to the effective management of the reserved book department and it is desirable to make a committee which will fix various decisions about the system. Whenever the director of the library make his decision, he must consult with his staff in order to involve them earnestly in the operation of the system.

This study suggested the methods of record management for the heads of local government, which would be the most valuable among local records. In order to conduct a systematic record management for the heads of local government, this study suggested the methods of establishing a record management system regarding regulation arrangement, production registration, preservation, utilization and services. First of all, in order to estimate the record category of the heads of local government, the study examined the duties of the offices of the deputy heads of local government, secretary's offices and information offices, which have been subsidiary & assistance branches in charge of producing the record. In addition, it investigated the present conditions of record management for the heads of local government through the interviews with secretary offices and information offices belonging to 16 cities and provinces and the claims for information disclosure and found out the following problems. They included incomplete record production, non-registration of produced records, abolition of records and taking them out of designated places with due notice, record preservation period regardless of the term of the heads of local government, varied preservation period for the records of the heads of local government by local self-government, short preservation period of primary records and non-management of home pages after the term of the heads of local government. To solve such problems, the study suggested the regulation arrangement for record management and a record management system. The regulation arrangement could be obtained through the establishment of the administrative organization setup condolence etiquette enforcement regulation and the recorders in local government and the revision of operation rules and through the revision of the reference plan for operation rules enactment of recorders from National Archives of Korea. As for the record management system, the study suggested the establishment of production, registration and preservation system of records for the heads of local government and the utilization and services of their records. In order to produce and register the records, the unit assignments should be founded by department in charge of the duties related to the records of the heads of local government on record management criteria, thus letting the staff surely produce and register the records. In terms of utilization and services of the records, the study suggested the use of websites and drawing up the record list, through which each record viewer would be able to figure out which records have been managed through the list services and which services could be given to the residents, thus letting the residents and the heads of local government who finished their term of duties use the records.
