The purpose of this study is to establish some concepts, objects, and methodologies which are essential components in the theoretical inquiry of Landscape Architectural Criticism(LAC), and to explore the structure of LAC. Theough comparing the artistic characteristics of landscape architecture with the latent criticism in it, and introducing some important concepts of criticism and aesthetics, the concept of LAC is defined operationally. And through grasping changes of the definitions and concepts about landscpae architecture, and classifying the fields of it which are related to critical structure, the objects of LAC are established. According to Virgil C. Aldrich and many other aestheticians, general aspects of criticism are divided into $\circled1$analysis, $\circled2$ evaluation, $\circled3$interpretation, and $\circled4$description. Through these aspects and Wayne Attoe's opinion(which seemed to be generalized in architectural), the pertinent methodologies of LAC are explored.

Just in time backup of the essential materials at industry and military is very important. Especially in case of military essential materials at wartime is so important as it controls victory and/or defeat. This paper presents the new approach for just in time suppling the essential materials at the beginning wartime - security step of materials, reservation priority and quantity requirement degree. In order to build the new approach, we introduced the concepts of cost and effect analysis for each essential item. First of all, the developed model will be useful to maximize combat sustaning power under constraint of budget.

Rather than an abstract discourse, the purpose of this study is to outline the core concepts in the 2015 revised curriculum as a concrete teaching and learning method in the school context. We interviewed eight secondary science teachers and reported their perceptions and perspectives on core concepts using a backward design model based on the cyclical process of the platform, deliberation, and design for developing teaching and learning materials to understand core concepts. The participants perceived these core concepts differently, such as big ideas corresponding to the ultimate principle, minimum science concepts required for daily life, and primary and significant key concepts. In addition, this affects the association of teaching and learning. When core concepts are understood as transferable and expandable big ideas, there is a tendency to focus on the relationship between concepts and design project learning in a specific direction. However, if core concepts are identified as minimum science concepts at the level of science literacy, that can be recalled within the context of life, there is a tendency to emphasize on activities that make a meaningful difference to the lives of students with focus on case studies that are relevant to everyday life. Once core concepts are identified as key scientific content elements, such as basic or significant concepts, teachers recognize that it is essential to emphasize concept changes by correcting misconceptions, acquiring accurate scientific knowledge, and developing problem-solving items through paper-and-pencil evaluation. As the 2015 revised curriculum is finalized and the 2022 revised curriculum is scheduled for release, effective policy support is required to ensure that the curriculum is revised, which emphasizes the purpose of big ideas by naming core concepts as core ideas, to be stably implemented in schools.

This study is focused on the main concepts of gravity and geomagnetics which are introduced in the earth science textbooks of high school in 7th curriculum. This study examines the validity and accuracy of the Earth Science textbooks and shows some effective teaching plans by using the latest materials. This study also illustrates the main concepts of gravity and geomagnetics through presenting some effective and practical teaching-learning methods. The results of the study were as follows: First of all, a number of main concepts of six textbooks of high school were selected; the field of gravity, the direction and dimension of gravity, the measurement of gravity, the main reason of gravity anomaly and geoid, earth terrestrial magnetic field, secular variation of goemagnetics. Secondly, most Earth Science textbooks of high school explains the main concepts of the gravity and geomagnetics in similar ways. Those textbooks, however, don't put an emphasis on the essential contents which has been regarded as important thing in terms of the current educational course of study. The high school textbooks also use the material which is too old-fashioned and has some problems of accuracy and validity. Especially, many main concepts of the textbooks and scientific data(such as the direction of gravity, the measurement of gravity, the main reason of gravity anomaly, the use of geoid, secular variation) are different with those of South Korea, In addition, some materials(graphs and diagrams) are very old ones and they don't have authentic information.Finally, Among the various main concepts, some important ideas (the direction of the gravity and the method of measuring gravity, the measurement and use of gravity anomaly, the definition of geoid and secular variation of geomagnetics) should be corrected by showing the latest and authentic materials.

Ontology schema reasoning is used to maintain consistency of concepts and build concept hierarchy automatically. For the purpose, the search of concepts must be inevitably performed. Ontology schema reasoning performs the test of subsumption relationships of all the concepts delivered in the test set. The result of subsumption tests is determined based on the creation of complete graphs, which seriously weighs with the performance of reasoning. In general, the process of creating complete graph has been known as expressive procedure. This process is essential in improving the leading performance. In this paper, we propose a method enhancing the classification performance by identifying unnecessary subsumption test supported by optimized searching method on subsumption relationship test among concepts. It is achieved by propagating subsumption tests results into other concept.

In developing total hospital information system, large amount of time and expense are to be spent while its results are likely to lead itself to end-users' dissatisfaction. Some of the main complaints on the part of end-users come from insufficient consideration of end-users environment as well as inappropriate representation of their requirement in the system alalysis and design. This papre addresses some advantages of Essential Logical Modeling Process for better analysis and design, explaining by example the developmental process of the Patent Management and Accounting System for a tertiary care hospital. In the case, the Essential Model, suggested by McMenamin and Palmer, proved to be an effective tool for clear separation of analysis and design phase and for better communication among system developers and with end-users. The modeling process itself contributed to better program modularity as well, shown in a Structured Chart. Difficulties in learning how to identify' essential activities' for the modeling practice were experienced in the beginnins stage, which were, however, overcome by elaborating some heuristic guideling and by rdferring to necessary tools including State Transition Diagram, Control Flow Diagram, and so many. While full evaluation of the Essential Model usag remains to wait till the completion of the case project, its strengt in making clear distinction between analysis and design phase was enough to be attractive to system analysts. The model concepts are open to many further application fields, particularly such areas as business re engineering, process remodeling, office automation, and organizational restructuring.

Purpose: Supply chain management is a significant component of marketing strategy to achieve the overall goal of maintaining a competitive edge in the industry. To better understand and compare marketing strategies between two major distribution channels (Wholesalers and Retailers), the present study examines the various critical aspects in developing marketing strategies based on numerous prior studies. Research design, data and methodology: Qualitative research involves collecting and analyzing various non-numeric data to establish different concepts or opinions in the data. In content analysis, determining the presence of different themes, concepts, or other valuable texts and their relationships is carried out. Usually, the researchers employ three distinct methods to carry out complete content analysis. Results: Developing the appropriate marketing strategy to manage the supply chain of a business is essential. Marketing strategies should be formulated in a manner that ensures the supply chain is well organized. Applying the marketing strategy in the supply chain management, the current author utilizes the four Ps to integrate strategies for two distribution channels which are essential in ensuring proper management. Conclusions: This study concluded that utilizing the existing marketing strategies and integrating them can help in better management of the supply chain, using communication, decision making, product differentiation, and pricing.

Background: There is growing international recognition of the need for improvements to national chemical management systems for hazardous chemicals. The European Union has recently introduced the concept of 'essential uses' as a new approach to the management hazardous chemicals by limiting their uses. Objectives: This paper examines the concept of essential uses in chemical management and how to apply it through a case study of essential use. This approach is distinct from the current chemical management system, but seeks to improve its potential benefits by effectively restricting or gradually decreasing the use of hazardous substances. Methods: The concept of essential uses was introduced by reviewing the Montreal Protocol on Substances that Deplete the Ozone Layer, Cousins's three essentiality categories applied to PFAS, restriction options assessed in the PFAS restriction proposal under REACH, and the California Safer Consumer Products regulations prioritizing 6PPD in motor vehicle tires. Based on these essential uses concepts for PFAS and 6PPD, uses of benzene were classified in accordance with the essential uses approach for products using benzene in South Korea. Results: The essential use concept is able to manage the restriction and authorization of substances of concern through essential uses and non-essential uses and the feasible substitution of uses and substances. Conclusions: If the concept and methodology of essential uses are clearly established, they can be expected to shift the national chemical management paradigm from regulating substances to limiting uses under the existing substance management system.

In order to grasp the clear concepts and variables to treat Shanghan diseases which has complex meaning by each medical literature, several concepts and analytic method of structuralism from early to late stage encompassing Saussure and Derrida were used. Main concepts are langue and parole, signifiant and signifie, syntagme and paradigme, denotation and connotation, synchronie and diachronie, identity of structure and differance etc. and methods are substituting these concepts to historical Shanghan theories from Zhongjing to Ming-Qing dynasty and comparisons of synchronie about their era. Essential qualities of Shanghan diseases are pathologic phenomena under the order of unification of nature and man formed through concrescence between individual human body and geo-climatico-socio-cultural environmental conditions, neither injuries by cold pathogen nor five types of exopathogenic febrile diseases. The former environmental elements can be inferred from general traits of desires and public pathological aspects of social members, and the latter personal factors from corresponding features to those pathogenic variables. In addition, the concepts of Shanghan disease are added successively up to now via Jin-Yuan's four great masters and Wenbing masters, and thus the new concepts of denotation became another connotation obtaining new signifiant. In this way, for the treatment of Shanghan diseases, new theories should be made for ranging prescription over the wenbing field; reflecting not only climatical variables but also each patient's physio-pathological features and sociocultural variables. Thereby an appropriate and reasonable therapeutical systems can be designed and can guide research direction hereafter.

Objectives: The aim of this study was to establish a clear diagnostic definition of Sanhupung using the Delphi method. Methods: This study used the Delphi technique. A panel consisting of 21 experts of Korean medicine, particularly in of gynecologic medicine, participated in the Delphi examination that included answering the 4th round survey. The Delphi examination was carried out through evaluating and correcting the questionnaire by e-mail. Results: Through the Delphi survey, we have reached on an agreement regarding the basic concepts, time, cause, essential symptoms, and accessory symptoms of Sanhupung. They are as follows: 1) Sanhupung is a culture bound syndrome reflecting Korea's cultural specificity. 2) Sanhupung can be diagnosed even after the miscarriage. 3) For the diagnosis of Sanhupung, the main cause of symptoms should not be classified as other disease. 4) Sanhupung can be diagnosed based on essential symptoms and accessory symptoms. 5) Essential symptoms include local symptoms such as joint pain at specific areas, partial sensory impairment and general symptoms including pain of all the joints, whole body sensory impairment, increased sweating, feeling of wind coming into the body, worsened symptoms with the cold, intolerance to cold, and pain of all the muscles. Conclusions: The basic concepts and diagnostic definition of Sanhupung were suggested based on the Delphi survey among experts in the field. Further research is necessary to improve reliability and validity of diagnostic definition of Sanhupung in clinical trials.
