A jetfighter shape modeling method based on design features is researched, to improve the efficiency of shape modeling in the stage of conceptual aircraft design. The aircraft's general design features and shape parameters, including geometric and position parameters, are described. The coordinate systems of the entire aircraft and its components are defined. As a sample of local shape, a method of inlet intake modeling is introduced. The whole process of the modeling method is proposed. Three examples of different jetfighters are listed, to describe the achievement of basic layout, which includes four main elements. The Fusion of Components can be achieved by regulating the details of the sections of the fuselage. Sample Cases of typical layouts are shown to verify the effectiveness of the proposed method, which provides the basis for further analysis and optimization.

Purpose - As the role of salespersons in retail stores has expanded from selling products to sharing brand experiences with customers, the importance of research on the effects of salesperson-brand relationships has grown. The purpose of this research is to investigate the influences of salespersons' brand identification on conceptual fluency and customers' service and brand evaluations. It was supposed that salespersons' brand identification is affected by brand knowledge, which is a core dimension of internal branding. Research design, data, and methodology - The author developed a structural model in which salespersons' brand knowledge influences brand identification, hence customers' perception of salesperson-brand image congruence. And it is hypothesized that salesperson-brand image congruence influences conceptual fluency which affects customers' satisfaction and brand evaluation. Data were collected from five department stores in Seoul. Results - First, salespersons' brand knowledge was found to have a significant effect on brand identification. The more a salesperson knows about the affiliated brand, the higher her level of brand identification. Second, salespersons' brand identification influenced salesperson-brand image congruence. Third, salesperson-brand image congruence had a significant effect on brand conceptual fluency. Customers who perceive salesperson-brand image congruent are more likely to process information easily. Finally, conceptual fluency was found to be a significant determinant of store loyalty and brand value evaluation. Conclusions - The results of this study verify importance of salesperson's brand identification on customers' service and brand evaluations. To enhance salespersons' brand identification, retailers should emphasize the importance of internal branding and communication, especially by sharing brand vision, values, and identity with employees at customer contact points. Also, as brand conceptual fluency is a significant determinant of customer responses, retailers need to deliver consistent messages through various components of store environments, including salespersons' attitudes, appearances, and manners, as well as physical store design. With a deeper understanding of the effects of salesperson-brand relationship and brand conceptual fluency, retailers will be able to create more effective brand strategies to enhance their performances. Future studies should consider data from various retail types, such as discount stores, to generalize the findings.

Purpose:The objective of this study was to identify the conceptual constructs of patient centeredness from the perspective of patients and family members in Korea, and to compare them with those included in the Picker Institute framework. Methods: Two focus group discussions were conducted. Each focus group consisted of six participants who had experienced being either a patient or a caregiver. We carried out a thematic analysis, and then compared the contents of our focus group discussions with the components of patient-centered care outlined by the Picker Institute. Results: Six conceptual constructs of patient centeredness emerged from the focus group discussions. Five of these overlapped with those outlined by the Picker Institute: 1)respect for patients' values, preferences, and needs, 2) coordination and integration of care, 3) information, communication, and education, 4) physical comfort, and 5) emotional support and alleviation for fear and anxiety. A new component that was not mentioned in the Picker Institute framework emerged from this study: "ease of making a complaint." Currently, "involvement of family and friends" and "continuity and transition" were not prominent components of patient centeredness according to our focus group discussions. Conclusions: This study presents the conceptual constructs of patient centeredness, five of which overlap with those outlined by the Picker Institute, and provides a qualitative basis of the patient experience survey currently being implemented by the Health Insurance Review & Assessment Service in Korea.

본 연구는 개념적 혼동(conceptual muddle) 상태에 있는 방송과 통신의 핵심적 이념이자 정책 목표인 공익성과 보편적 서비스를 개념적으로 구명(究明)하고자 하였다. 본 연구에서는 (1) 공익성과 보편적 서비스 개념의 기원, (2) 공익성과 보편적 서비스 개념의 구성 요소, (3) 공익성과 보편적 서비스 개념의 현실적 구현이라는 세 가지 측면에서 살펴보았다. 주요한 연구 결과는 다음과 같다. 첫째, 공익성과 보편적 서비스 개념의 기원은 지역적 차이가 있었다. 방송의 공익성 개념은 서구에서 시작되어 미국을 비롯한 세계 모든 나라 방송 이념으로 뿌리를 내린 반면, 보편적 서비스 개념은 미국에서 시작되어 유럽을 비롯한 국가들의 정보 통신 정책의 주요 이념으로 자리 잡아가고 있었다. 둘째, 양 개념의 구성 요소를 살펴본 결과, 공통점보다는 차이점이 더욱 크게 나타났다. 가장 현저한 양 개념의 공통점은 '보편주의'인 것으로 밝혀졌다. 공익성 개념은 보편적 서비스 개념을 포함하면서, 그 외 독립성, 다양성, 질, 지역성과 같은 내용과 관련된 차별적 구성 요소를 내포하고 있다. 셋째, 양 개념의 정책 구현이라는 측면에서 비교 분석한 결과, 양 개념간에 많은 차이가 있었다. 공익성 이념은 방송 사업자에 대한 규제 정책 위주로 전개된 반면, 보편적 서비스 이념은 이용자에 대한 지원 정책으로 나타나, '규제'와 '육성'이라는 정책적 대조를 보였다. 결론적으로, 양 개념은 차별적 개념이기 때문에 학문적 차원에서 사용할 때 엄밀성을 유지할 것이 요구되고, 실제적인 차원에서는 관련 법 제 개정 시 방송에 있어서도 보편적 서비스 의무를 부과하도록 건의하였다.

Ecosystem health assessment is an emerging concept regarded as a useful diagnostic tool for evaluating ecosystems. The stability of ecosystem is the main theme in the assessment. Generally, two components - resilience and resistance - are involved in the mechanism of ecosystem stability. In this study, relative degrees of the resistance and the resilience were quantified for most aquatic Insects Inhabiting running waters in Korea. A total of 34 groups were newly categorized based on previous studies, and a conceptual model has been produced. The model was applied for the aquatic insect communities inhabiting different streams and demonstrated that each stream ecosystem possessed different degrees of stability. This study also indicated that it was possible to compare stabilities of different ecosystems using relative degrees of resilience and resistance. Using the conceptual model, suitable conservation and management strategies could be recommended in ecological assessments. The model can be used as a stepping-stone for developing more comprehensive methodology that objectively diagnoses and evaluates the ecosystem stability.

This paper describes a step-by-step method to minimize design iterations in a process of product design change. In the design process, two components are coupled if a change of a component can require the other components change, and design iterations are generated by the coupling. The design iteration is one of main factors that increase design effort. In this study, three matrices are used to solve the design iteration of automatic transmission lever, Requirement-Engineering matrix, Engineering-Components matrix, and DSM(Design Structure Matrix). Firstly, with the DSM, the product architecture and conceptual design process are proposed from product function analysis. Secondly, with the QFD, the Requirement-Engineering matrix and Engineering-Components matrix present the relationship among customer requirements, engineering issues, and product components. Lastly, the results of the QFD analysis are used in the DSM to solve the component interactions and to provide design

Object orientation has become the predominant paradigm for conceptual modeling (e.g., UML), where the notions of class and object form the primitive building blocks of thought. Classes act as templates for objects that have attributes and methods (actions). The modeled systems are not even necessarily software systems: They can be human and artificial systems of many different kinds (e.g., teaching and learning systems). The UML class diagram is described as a central component of model-driven software development. It is the most common diagram in object-oriented models and used to model the static design view of a system. Objects both carry data and execute actions. According to some authorities in modeling, a certain degree of difficulty exists in understanding the semantics of these notions in UML class diagrams. Some researchers claim class diagrams have limited use for conceptual analysis and that they are best used for logical design. Performing conceptual analysis should not concern the ways facts are grouped into structures. Whether a fact will end up in the design as an attribute is not a conceptual issue. UML leads to drilling down into physical design details (e.g., private/public attributes, encapsulated operations, and navigating direction of an association). This paper is a venture to further the understanding of object-orientated concepts as exemplified in UML with the aim of developing a broad comprehension of conceptual modeling fundamentals. Thinging machine (TM) modeling is a new modeling language employed in such an undertaking. TM modeling interlaces structure (components) and actionality where actions infiltrate the attributes as much as the classes. Although space limitations affect some aspects of the class diagram, the concluding assessment of this study reveals the class description is a kind of shorthand for a richer sematic TM construct.
