Software is continuously changing during development and after development. When a change is required, it is difficult to precisely grasp the scope of impact intuitively. A systematic method is needed to accomplish the required change. The purpose of impact analysis on software change is to avoid missing any information by recognizing the ripple effect that the change might cause. This paper proposes a dynamic method that can easily identify the scope of change request by using the association between use-case scenarios and artifacts of UML modeling in object-oriented development environment. By using this approach, the scope of impact that the change might have on other components such as class diagram and sequence diagram in use-case scenarios can be identified by forward tracing. In addition, analysis of influence of possible further changes due to changes in other components can be identified iteratively through backward tracing. The results of this paper are not limited to impact analysis on artifacts and change type. They can also be used as basic guidelines during impact analysis for various change requests.

These days, Emotional Design is on the sustainable development through activity study thogh, until now, the study proceed too far with Sensibility Ergonomics applied to SD. However, on this paper, the study would be make progress through GSD that it applied to Verb. For this reason, applied to Emotional Design consideration of theory through JOAN MEYERS-LEVY's papaer titled "The Influence of Ceiling Height", Laban Movement Analysis and Aspect of Semiotics and then judgement of GSD would be make progress through experiment to collection of Emotional Vocabularies and evaluation of body movement. There is a method of analysis by using statistical program such as SPSS 18.0 and it would have validity of analysis. Here is a result of this study. According to heights of ceiling types(2.4M, 3.0M) there are differences between behavior of Figure Attachment, Emotional Vocabularies of the event and Body Movement. While the Figure Attachment has a tendency to restricted scope, CH has a tendency to make attachment within the scope. You could see the Negative Adjective for Emotional Vocabularies at CL and the Positive Adjective ranges at the CH. Basic body movement for passive, 'moving' and 'stretching' as shown at CL more than the CH. For active movement which has purpose, 'moving the weight' and 'stretching' as shown at CH more than at CL.

The purpose of this study is to identify the legal definition and usage of cultural property term related to the architecture within the cultural property-related legal system and general legal system, and to present proper terminology and specific concepts that can be used for the architecture as cultural properties. In the current cultural property legislative system, terms about the architecture are diverse and obscure, and the definition of each term is different from the concept in the general legal system. In this context, this study presented the terminology of 'the architectural heritage' as 'a cultural property by construction act' to cover whole cultural properties related to Korean architecture. And the conceptual scope of the architectural heritage is divided into the technology and the performer related to the act, the record and the building related to the product. and Each concept needs to be specifically tailored to its object and scope. Systematic definition of terms for cultural properties related the architecture can positively influence systematization of cultural property preservation and management as well as empirical research and education on Korean architecture.

This study was performed to search for the geometrical principles in modern architecture and design based on Frobel's educational idea and Kindergarten system. Especially, it studies on the geometrical principles of Froebel's building gifts and it's types, and then illustrates applied examples in modern architecture and design. As the architectural scope, the architecture and design theory of Frank Lloyd Wright and Bauhaus in early 20th century is analyzed. The conclusions of this study that starts these purpose are as follows. First, Froebel's educational theory is based on principles and rules which are perceived through the observation of nature, and Froebel's Kindergarten system consists of geometrical building gifts and categories of geometrical forms. Second, the characteristics of Froebel's building gifts are mathematical size, proportion, symmetry and the rules of spatial relation. Third, the influence of Froebel's kindergarten system on Bauhaus is that it based on the rational rules of $\bigtriangleup\square\bigcirc$ organized by geometrical basic forms as like Froebel's educational idea. And the influence of Froebel's Kindergarten system on Frank Lloyd Wright is that he used unit system, unity of space and structure and modular system as like the Froebel's building gifts.

Within the scope of the plane-strain state, by utilizing the three-dimensional linearized theory of elastic waves in initially stressed piezoelectric and elastic materials, Lamb wave propagation and the influence of the initial stresses on this propagation in a sandwich plate with pre-stressed piezoelectric face and pre-stressed metal elastic core layers are investigated. Dispersion equations are derived for the extensional and flexural Lamb waves and, as a result of numerical solution to these equations, the corresponding dispersion curves for the first (fundamental) and second modes are constructed. Concrete numerical results are obtained for the cases where the face layers' materials are PZT-2 or PZT-6B, but the material of the middle layer is Steel (St) or Aluminum (Al). Sandwich plates PZT-2/St/PZT-2, PZT-2/Al/PZT-2, PZT-6B/St/PZT-6B and PZT-6B/Al/PZT-6B are examined and the influence of the problem parameters such as piezoelectric and dielectric constants, layer thickness ratios and third order elastic constants of the St and Al on the effects of the initial stresses on the wave propagation velocity is studied.

The paper examines the reaction of the Z-Vietnam generation to online TV advertising (TVC), which elements of online TV advertising has a positive influence, which factors do not affect or negatively affect their consumption decisions for the advertised goods. Data for the study was collected from 300 Vietnam's Generation Z in Ho Chi Minh City through live interviews or questionnaires through Google Docs Forms, with over 30 questions. The six basic factors that influence the reactions of Generation Z consumers are information, entertainment, irritation, credibility, interaction, and advertising value. The research results show that, due to the influence of social media and generational characteristics, most consumers of the Generation Z in Vietnam have a favorable attitude towards online TV advertising, and they appreciate this form of advertising. Information element, irritation, credibility and entertainment have a strong and positive impact on TVC. The other two factors are advertising value and interaction, which does not significantly affect the reaction of this generation. This study needs to be checked and reviewed by subsequent studies on a larger scale and in a wider scope because the study only conducted random sampling on a small scale, did not meet the requirements for representation and generality.

The bi-material elastic system consisting of the circular hollow cylinder and the infinite elastic medium surrounding this cylinder is considered and it is assumed that on the inner free face of the cylinder a point-located axisymmetric time harmonic force, with respect to the cylinder's axis and which is uniformly distributed in the circumferential direction, acts. The shear-spring type imperfect contact conditions on the interface between the constituents are satisfied. The mathematical formulation of the problem is made within the scope of the exact equations of linear elastodynamics. The focus is on the frequency-response of the interface normal and shear stresses and the influence of the problem parameters, such as the ratio of modulus of elasticity, the ratio of the cylinder thickness to the cylinder radius, and the shear-spring type parameter which characterizes the degree of the contact imperfectness, on these responses. Corresponding numerical results are presented and discussed. In particular, it is established that the character of the influence of the contact imperfection on the frequency response of the interface stresses depends on the values of the vibration frequency of the external forces.

Purpose: Previous studies have shown that consumers feel more happiness when they have experiential purchases than material purchases. This experiential advantage has aroused great concern of researchers in the field of social and consumer psychology. Focusing on this issue, the paper aims to tease out the relevant academic work and to further provide with some significant implications. Research design, data and methodology: The paper has divided the review into the following parts. Firstly, the connotation of experiential purchase and material purchase has been simply defined; Secondly, based on the logical framework of pre-factor variables, intermediary variables and regulating boundary conditions, this paper has collated the causal chain of the influence of purchases types on happiness; Finally, this paper has reviewed and summarized the shortcomings of existing studies, and have pointed out specific objectives of future research. Results: From the perspective of time utility and space form, this paper has expounded the substantive differences between the two types of purchase, which lays a foundation for the explanation of the follow-up mechanism. Moreover, the paper has mainly interpreted the intermediary mechanism from two aspects, namely, individual elements of consumers and social elements of consumption situations. Conclusions: This study expands the scope of previous happiness research and strengthens the negative events adaptation research.
