가능최대홍수량(PMF)이란 가능최대강수량(PMP)을 입력으로 한 강우-유출해석의 결과를 말한다. 즉, 대상유역의 가능최대강수량을 산정하여 시 공간분포를 고려한 가능최대호우를 결정한 후, 강우-유출관계를 이용하여 최대홍수량을 산정하는 것이다. 이러한 과정을 거쳐 산정된 가능최대홍수량은 실무에서 댐 설계를 위해 사용된다. 본 연구에서는 가능최대홍수량을 설계홍수량으로 채택하고 있는 국외의 강우-유출 해석 방법에 대해 조사하고, 국내의 경우와 비교하였다. 그 결과, 평균 개념의 Clark 단위도를 사용할 경우 홍수를 과소평가할 우려가 있으며, 큰 홍수사상을 모의하기 위해서는 최대 개념을 적용한 단위도의 도입이 필요하다고 판단하였다. 최대 개념을 적용한 기존의 연구들 또한 관측 기록년 이후에 기록된 수문량에 비해 월등히 큰 수문량이 발생할 때, 과거의 자료를 토대로 추정한 PMF의 신뢰성이 급격히 저감된다는 한계가 존재하므로, 국내 모든 유역에 적용할 수 있는 일관성 있는 단위도가 필요하다. 따라서, 본 연구에서는 특성 속도를 고려하여 빈도해석을 실시하였고, 이를 이용하여 최대 개념을 고려한 유역의 특성속도에 따른 Clark 단위도를 제시하였다. 아울러 단위도의 변화에 따른 가능최대홍수량의 변화를 검토하여, 단위도의 적용성을 평가하였다.

The purpose of this study is to present types of design concept based on the specificity of landscape design, and to derive a theoretical framework for the landscape design concepts by analyzing the design concepts appearing in urban park design competitions. Through literature review, five types of landscape design concepts were categorized into value and vision, analysis and interpretation, form and structure, program and element, and process and operation. Using this framework, the design concepts shown in 96 works submitted to 18 domestic and overseas urban park design competitions were analyzed. The results of the analysis are summarized as follows. First, due to the complexity of contemporary urban parks, design concepts are presented as mixtures of main concepts and secondary concepts in multiple layers. Second, it was identified that design concepts of 'form and structure' were used the most in urban park designs, followed by the 'program and element' concepts. The 'value and vision' and 'analysis and interpretive' concepts are introduced as third and fourth. Third, the reason that the 'form and structure' concept is widely used as main and secondary concepts is judged to be because the form of a space, which is the key result of the design, has an important influence on the identity of the design. Fourth, the reason that the 'program and element' concept type is widely introduced is that urban park design has a stronger planning aspect to produce programs during the design process, compared with other design fields where programs are usually given in advance. Lastly, it is difficult to see that the properties of the site solely affect the type of design concept, because a design concept is the result of a complex and creative process in which a designer subjectively interprets the objective characteristics of the site and project, and given design guidelines can affect the type of design concept.

Formal Concept Analysis (FCA) is a widely used methodology for data analysis, which extracts concepts and builds a concept hierarchy from given data. A concept consists of objects and attributes shared by those objects, and a concept hierarchy includes information on super-sub relations among the concepts. In this paper, we propose a method for extracting Implication and Association rules from a concept hierarchy given a query by a user. The method also describes a way for displaying the extracted rules. Based on this method, we implemented an automatic tool, QAG-Wizard. Because the QAG-Wizard not only elicits relation information for the given query, but also displays it in structured form intuitively, we expect that it can be used in the fields of data analysis, data mining and information retrieval for various purposes.

The purpose of this study was to analyze the cliche for English-Korean interpretation and translation with special reference to the cliche based on the Holy Bible texts. Cliches are figurative or literal expressions and are overused expressions in various different cultures. In addition, cliches are languages, a tool of communication in an appealing way. Therefore, cliches are must be clearly distinguished from the term of idioms that are figurative phrases with an implied meaning; the phrase is not to be taken literally. Also, cliches are the single most important factor that characterizes socioculturally. Through this empirical analysis on cliches we see that this study has conceptualized the meaning of cliche. Based on this result, I expect that anyone who researches English-Korean interpretation and translation field should be concerned about cliches. I hope this study will be a guide to the right uses of cliches in English language fields.

The purpose of this study is to consider the impact on the degree of turnover of the professional self-concept and the emotional labor. This study were subjected to empirical analysis on female children's hospital nurses. The results of the analysis, only emotional labor and task satisfaction among the components of the professional self-concept became statistically significant results. The relationship between professional pride and task satisfaction have a significant effect on turnover. The relationship only of surface acting and turnover between those of emotional labor and turnover became significant. Based on the research results, it should be preferred to nurse specialists in the women's hospital, in order to lower the turnover of nurses. Management strategies of the organization should be sought to improve operational feeling of satisfaction, and Also the approach should be applied to ease the negativity of surface acting.

The purpose of this study is to identify the relationships among Social maturity(SM), Self-directed learning(SDL) and Self-concept of professional nursing(SCPN), and influencing factors of SCPN of nursing students. The survey was performed on 221 nursing students in two universities. Data were collected using a structured questionnaires and analysed with PASW 22.0. Study findings revealed that SCPN has a significant correlation with SM and SDL. Major satisfaction(${\beta}=.179$), Meaning on nursing(${\beta}=.274$), SM(${\beta}=.118$) and SDL(${\beta}=.211$) about SCPN were significant predictive variables. This variables accounted for 34.4% of the variance in SCPN. The findings indicate the necessity of developing educational programs to enhance nursing students's SM and SDL for increasing positive SCPN.

This article examines not the term "the public" or "publics"-which has various meanings-but its particular meaning, which is a group of citizens who engage in political discussion and debate with fellow citizens in order to form shared understandings and common judgments with regard to contemporary affairs and public issues. The goal of this article is to show the importance of this concept in critical studies of media and society and to analyze how this concept has been accepted in South Korean critical communication studies. In this article, critical communication studies refer to communication studies that aim to explore social meanings of communication phenomena. This article argues that little attention has been paid to the concept of the public as agreement-oriented discursive political participants in South Korean critical communication studies.

Community music therapy (CoMT) has been recently developed and expands the opportunities for music therapy. The concept of CoMT is introduced in this article, and its three attributes of community, music, and health are reviewed. This study specified each attribute of CoMT: a community (a group of people, a field where members of a group interact with each other), music (a substance of interaction, collective music-making), and health (motivation and goal of interaction, relational and social well-being). The application and interactions of the three attributes of CoMT are introduced as in the concept of community music, music and health, and community health. How CoMT can be applied to the field of music therapy is also detailed and based on the concept of CoMT and its relationship with the attributes, the CoMT was reconstructed as CoMuHeal in this study. Future studies are needed to propose how music therapy approaches can be developed to provide music for well-being and better health in the community and how CoMT can be applied in collaboration with other professional fields.

For extracting and processing information explicitly from given data, Formal Concept Analysis(FCA) is provided a method which is widely used for data analysis and clustering. The data can be structured into concepts, which are formal abstractions human thought allowing meaningful comprehensible interpretation. However, most FCA tools mainly focus on analyzing one-valued contexts that represent objects, attributes and binary relations between them. There we few FCA tools available that provide scaling and analyzing many-valued contexts representing objects, attributes and relations with attributes' values. In this paper, we propose not only a scaling algorithm for interpreting and simplifying the multivalued input data, but also an algorithm to generate concepts and build concept hierarchy from given raw data as well. Based on these algorithms, we develop an automate tool, FCA Wizard, for concept analysis and concept hierarchy. We also present FCA Wizard based applications in medical domain.

This study analyzed issues in the mathematics curriculum concerning the cognitive development of the vector and inner product concepts in the light of Tall's and Watson's research(Tall, 2004a; Tall, 2004b; Watson et al., 2003; Watson, 2002). Some suggestions in teaching the vector and inner product concepts were elaborated in the terms of these analyses. First, the position vector needs to be represented by an arrow on the coordinate system in order to introduce the component form of a vector represented by a directed line segment. Second, proofs of the vector operation law should be carried out by symbolic manipulations based on the algebraic concept of a vector in the symbolic world. Third, it is appropriate that the inner product is defined as $\vec{a}{\cdot}\vec{b}=a_1b_1+a_2b_2$ (when, $\vec{a}=(a_1,a_2)$, $\vec{b}=(b_1,b_2)$) when it comes to considering the meaning of the inner product relevant to vector space in the formal world. Cognitive growth of concepts of the vector and inner product can be properly induced through revising explanation methods about the concepts in the curriculum in the basis of the above suggestions.
