As software is varied and grew in size, the importance of clear understanding and representing customer's need, has been emphasized. It is not easy to drive and define critical system needs, since requirements in early stage of the development, is and conceptual. Technical perspective view, Several theoretical analysis methods and validation techniques are introduced, but in practice, it is hard to drive clear customer's requirement. In this paper, to drive clear customer's requirements, Macrostruktur concept of textlinguistics is used. First, Macrostruktur of textlinguistics is used to analysis descriptive requirements. Second, Macrostruktur-rule is applied to analyzed Macrostruktur data in order to derive Macrostruktur-propositions. Finally, it is proposed to generating Use-case model using derived Macrostruktur-propositions.

This study discusses the conceptual definition of a balcony and the emergence of basic-type and expansion-type floor plans according to the balcony utilization. In addition, the change in building density is analyzed with regard to real cases, and base data are offered for future urban policies in Incheon Metropolitan City. The context of the Building Acts could be understood through the analysis of various balcony definitions and characteristics, and the analysis was divided into basic and extension types according to the legalization that occurred in 2005. The issue of density according to balcony expansion is discussed through theories, and a planned attempt at density management in the target area is investigated. The building area, floor area, and floor area ratio are discussed with regard to the target area, and the density management is empirically proven, which is different from the Unit Plan.

Atmospheric visibility is one of the indicators used to evaluate the status of air quality. Based on a conceptual definition of visibility as the maximum distance at which the outline of the selected target can be recognized, an image analysis technique is introduced here and an algorithm is developed for visibility monitoring. Although there are various measurement techniques, ranging from bulk and precise instruments to naked eye observation techniques, each has their own limitations. In this study, a series of image analysis techniques were introduced and examined for in-situ application. An imaging system was built up using a digital camera and was installed on the study sites in Incheon and Seoul separately. Visual range was also monitored by using a dual technology visibility sensor in Incheon and transmissometer in Seoul simultaneously. The Sobel mask filter was applied to detect the edge lines of objects by extracting the high frequency from the digital image. The root mean square (RMS) index of variation among the pixels in the image was substantially correlated with the visual ranges in Incheon and Seoul with correlations of $R^2$=0.88 and $R^2$=0.71, respectively. The regression line equations between the visual range and the RMS index in Incheon and Seoul were VR=$2.36e^{0.46{\times}(RMS)}$ and VR=$3.18e^{0.15{\times}(RMS)}$, respectively. It was also confirmed that the fine particles ($PM_{2.5}$) have more impacts to the impairment of visibility than coarse particles.

Since the 21st century a free-form building has been noticeably constructed. Now the definition "the monumental architecture is a free-form one." has come to be established. As a free-form building became a landmark of the city and a factor rising a value of the building all around the world, it is currently required to consider a more efficient design process. Therefore this research aims to learn approaches of the lasting free-form design process by considering the design process of Dongdaemun Design Plaza(DDP) designed by 'Zaha Hadid' that is a typical free-form building of Korea and the correlation between the design in the conceptual stage and the BIM(Building Information Modeling) design in practical stage.

In this research, we analysed definitions and examples of conductor and electrolysis concept in middle school science textbooks. We also surveyed 9 senior pre-service teachers' understanding of the concept definitions and appropriate examples. From the analysis of the textbooks, we found that the possibility of misunderstanding of learners is high because of the broad definition concept and narrow list of examples. After confirming the differences among pre-service teachers' understanding of the subject through questionnaires and interviews, they also debated for a need to an agreement on scientific concepts. The pre-service teachers recognized the meaning of social constructivism and the need for an agreement process in teaching science concepts.

The software Process can be defined as the set of activities, rules, procedures, techniques and tools used within the production of software. A software process model is a conceptual representation of a real world software Process and can be described by process programming languages. In this paper, we present the language constructs of SimFlex designed for object-based software process programming. The design of SimFlex is based on the object concept, so that it can model complex software processes concisely both in syntax and semantics. Since the language constructs of SimFlex are derived from the analysis of major PSEEs and their associated process programming languages, SimFlex includes the core characteristics required for a desirable object-based process programming language. In addition, SimFlex is designed to act as a template software process definition language which could be included in specific PSEEs through customization appropriate to those PSEEs.

Purpose: Tuberculosis is an infectious condition with a high disease burden, and the stigma in patients with tuberculosis causes negative health outcomes. The purpose of this study was to define and clarify the concept of self-stigma among patients with tuberculosis. Methods: The analysis was conducted using Walker and Avant's conceptual approach. Twenty-seven studies met the selection criteria. Results: Self-stigma in patients with tuberculosis can be defined by the following attributes: 1) self-esteem decrement; 2) fear; 3) negative emotions to oneself; 4) social withdrawal; and 5) discrimination. The antecedents identified were 1) inappropriate knowledge of tuberculosis, 2) spread of improper health information through media and social communications, 3) stereotypes and prejudices, 4) visibility due to symptoms appearing, 5) recognizing the risk of infection, and 6) low financial status. The consequences were 1) concealing the disease, 2) treatment delay, 3) poor treatment adherence, 4) poor quality of life, and 5) deterioration in or lack of social activities. Conclusion: The definition and attributes of self-stigma identified by this study can be applied to enhance the understanding of stigma in tuberculosis patients and to improve communications between healthcare providers and researchers. It can also be used to develop theories and measurements related to stigma in patients with tuberculosis.

This paper aims at understanding the conceptual definition and the characteristics of happiness of korean university students. We analyzed the data using Hybrid model introduced by Schwartz-Barcott and Kim. The data was conducted from June, 2018 to July 2018. The participants in this study were 13 and an another part of the data was obtained from literatures regarding happiness of university students. We categorized Happiness of korean university students into eight attributes in four dimensions. In other words, The concept of happiness on korean university students is as follows: (i) Satisfaction of Individual's subjective, (ii) Satisfaction of Individual's objective, (iii) Achievement of goal, (iv) A positive cognition for the future, and (v) Relationship satisfaction from meaningful person, (vi) Physical and mental well-being of oneself and meaningful person, (vii) Satisfaction of everyday life, (viii) Satisfaction of college life. The major contribution from this paper is that we provide a guideline for establishing a strategy to reduce negative emotions and increase happiness of university students in korea by identifying the concept of Happiness on Korean university students. Based on this study, we recommend to develop an educational program to increase happiness of university students in korea.

In order to help students to understand the essence of prime concepts, this study looked at the history of prime concept development and analyzed how to introduce the concept of textbooks. In ancient Greece, primes were multiplicative atoms. At that time, the unit was not a number, but the development of decimal representations led to the integration of the unit into the number, which raised the issue of primality of 1. Based on the uniqueness of factorization into prime factor, 1 was excluded from the prime, and after that, the concept of prime of the atomic context and the irreducible concept of the divisor context are established. The history of the development of prime concepts clearly reveals that the fact that prime is the multiplicative atom is the essence of the concept. As a result of analyzing the textbooks, the textbook has problems of not introducing the concept essence by introducing the concept of prime into a shaped perspectives or using game, and the problem that the transition to analytic concept definition is radical after the introduction of the concept. Based on the results of the analysis, we have provided several pedagogical implications for helping to focus on a conceptual aspect of prime number.

Under the new media environment this study is designed to investigate how the concept, 'self-efficacy' would be applied in an advertising context. The current study reviews consumer-controlled media environment, consumers' various attitude toward advertising and strategies for coping for advertising. In addition, how self-efficacy has been defined and applied in politics, education, and the Internet was discussed. From the advertising perspective it is interesting to examine how self-efficacy would be defined and applied in the consumers' attitude toward advertising. Lastly, this study will examine effects of self-efficacy on advertising research and advertising industry. For further study on self-efficacy much research needs to be conducted, focusing on conceptual and operational definition. Specifically, scale development and validation tests of 'self-efficacy' should be preceded.
