Based on the consistent couple stress theory (CCST), we develop a unified formulation for analyzing the static bending and free vibration behaviors of functionally graded (FG) microscale beams (MBs). The strong forms of the CCST-based Euler-Bernoulli, Timoshenko, and Reddy beam theories, as well as the CCST-based sinusoidal, exponential, and hyperbolic shear deformation beam theories, can be obtained by assigning some specific shape functions of the shear deformations varying through the thickness direction of the FGMBs in the unified formulation. The above theories are thus included as special cases of the unified CCST. A comparative study between the results obtained using a variety of CCST-based beam theories and those obtained using their modified couple stress theory-based counterparts is carried out. The impacts of some essential factors on the deformation, stress, and natural frequency parameters of the FGMBs are examined, including the material length-scale parameter, the aspect ratio, and the material-property gradient index.

In this study, the factors affecting opportunism that causes conflict in the franchise system between franchisor and franchisee were analyzed based on the transaction cost theory and power-dependency theory. Hypothesis 1 states that franchisor support will negatively affect opportunism. Hypothesis 2 expresses that franchisee transaction-specific investment on the relationship with the franchisor will positively affect opportunism. Hypothesis 3 asserts that franchisee dependency on the franchisor will positively affect opportunism. All of these were supported. However, Hypothesis 4, maintaining that franchisee competitive intensity will positively affect opportunism, was not supported. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of franchisor opportunism that causes conflict in the franchise system by comprehensively applying the transaction cost theory and power-dependency theory. This study can also identify what a company should manage specifically to lower opportunism by identifying the antecedents of franchisor opportunism in the franchise system. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of franchisor opportunism in the franchise system have been extensively investigated from the transaction cost theory's and power-dependency theory's viewpoint. In the future, it is necessary to identify additional factors. Second, the study was conducted only from the franchisee's perspective. In future studies, more accurate research results can be obtained by simultaneously examining the franchisee's point of view and the franchisor's point of view.

In this study, the effect of reducing and increasing factors in relationship conflict on the relationship exit between auto parts suppliers and buyers was analyzed based on transaction cost theory and relational exchange theory. As a result of the hypothesis test, Hypothesis 1, which states that relationship commitment will hurt relationship exit, and Hypothesis 3 that replacement will harm relationship exit were supported. In addition, Hypothesis 2 which states that transaction-specific investment will positively affect relationship exit was not supported. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of relationship exit by comprehensively applying the transaction cost theory and relational exchange theory. In addition, this study can identify what a company should manage specifically to lower conflict and relationship exit by identifying the antecedents of relationship exit. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of relationship exits between auto parts suppliers and buyers have been extensively investigated in the viewpoint of the transaction cost theory and relational exchange theory. In the future, it is necessary to identify additional factors. Second, the study was conducted only from the supplier's viewpoint. In future studies, it is expected that more accurate research results can be obtained by simultaneously examining the supplier's point of view and the buyer's point of view.

In this work, free vibration analysis of size-dependent functionally graded (FG) nanoplates resting on two-parameter elastic foundation is investigated based on a novel nonlocal refined trigonometric shear deformation theory for the first time. This theory includes undetermined integral variables and contains only four unknowns, with is even less than the conventional first shear deformation theory (FSDT). Mori-Tanaka model is employed to describe gradually distribution of material properties along the plate thickness. Size-dependency of nanosize FG plate is captured via the nonlocal elasticity theory of Eringen. By implementing Hamilton's principle the equations of motion are obtained for a refined four-variable shear deformation plate theory and then solved analytically. To show the accuracy of the present theory, our research results in specific cases are compared with available results in the literature and a good agreement will be demonstrated. Finally, the influence of various parameters such as nonlocal parameter, power law indexes, elastic foundation parameters, aspect ratio, and the thickness ratio on the non-dimensional frequency of rectangular FG nanoscale plates are presented and discussed in detail.

The aim of this study is to review Norberg-Schulz's architectural phenomenology to find out its meaning and limitations in contemporary architecture. His phenomenological trilogy, 'Existence, Space and Architecture', 'Genius Loci' and 'The Concept of Dwelling' are main texts to examine background, characteristics, meaning and limitations of his theory in relation to Structuralism and Heidegger's thoughts. Heidegger's phenomenology, especially his dwelling concept, had great impacts on forming Norberg-Schulz's architectural phenomenology. However, since his architectural phenomenology was strongly influenced by Structuralism, his theories present unstable combination of phenomenology and semiotics. And this results in instrumentalization, and overlooking body movement and socio-economical elements in his theory. In spite of these limitations, his theory also shows possibility to go beyond the theory of Modern architecture and plays important role in suggesting direction for better environment through applicability from single building to city in Postmodern architecture. Another meaning of his theory lies in presenting theoretical background for new way to interpret regionalism and specific policy tool to make town planning in Finland.

This paper reviews Grammatical Mapping theory, a recently proposed theoretical paradigm for understanding children's acquisition of syntax, and ventures to apply the theory to the acquisition of semantics. Particularly, we focused on the domain of space, and proposed how children might acquire a unique system of spatial words in their mother tongue. Based on our review of evidence, we propose that there may be universal semantic primitives that serve as foundations of word meanings. We also propose that children must learn their mother tongue's semantic category system of spatial relations, from real time data. Finally, we argue that children's learning of word meanings may involve creation of a theory that makes sense to the child, and that this process of theory creation is possibly guided by universal principles and parameters.

The purpose of this research is to analyze the differences between literature (Belles-letters) class in DDC 19 and literature class in KDC 3. The results of the study can be summarized as follows : 1. The section of philosophy and theory of literature in DDC was subdivided according to the properties as including subsection of theory of criticism but KDC didn't subdivide this section. 2. In DDC, the subsections of 'rhetoric in specific languages' and 'rhetoric of specific kinds of composition' in rhetoric section was established and can subdivide according to each languages and subjects. These considerations can be useful as compared with KDC. 3. In DDC, collections or criticism of several literatures in specific forms can be more subdivide according to specific aspects or features dealing with in the collections or criticism by a n.0, pplying Table 3-A when specified more than the literary form. 4. Reviewing a notational rank to be assigned in literatures of specific languages, Latin literature and Classical Greek literature to be ranked in division in DDC was established as subsection in KDC to treat them as literatures of minor languages. 5. The DDC can sometimes a n.0, pply, in literatures of all languages, the notations of Table 3 to be subdivided again as specific kinds of literary forms, but KDC subdivided literary forms as specific kinds of each forms in only Korean, Chinese, Japanese literature. 6. In DDC, even literatures of minor languages are provided with 'the period table for the specific literature' under each literature of specific languages in schedules and these period tables can be a n.0, pplied a n.0, ppropriately, but period numbers in KDC was established in only Korean, Chinese, Japanese literature. 7. The optional use of letter prefixes or special numbers such as 828.99 to distinguish literatures of countries other than the "mother country" which makes the use of period tables feasible, but the KDC can only use to distinguish without the function of dividing a period such as DDC. 8. According to a n.0, pplying Table 3 and 3-A also in literatures of specific languages(810-890), a literature of specific languages, a specific literary form in literature of specific languages and a literature or literary form of specific period, in case of a n.0, pplying 'form divisions 08-09', can subdivide again by a specific aspect or feature dealing with in the works when specified. 9. For grasping the rate of subdividing, after selecting several sample-titles in literary field, they classified by DDC and KDC and gave a definite score in accordance with analytic small subjects. According to the results, the rate of subdividing in literature class of KDC is proved as less 22.8% than DDC. than DDC.

Family researchers had devoted little attention to Choice, Exchange theory by the time 1960. Being anchored by Thibaut & kelley(1959), this theory becomes one of the most widely used theoretical frameworks for family research. Waller's(1938) famous rating-dating hypothesis was intrinsically an exchange formulation. Blood and Wolfe(1960) employed the concept of rewards in their theory of family power. Farber(1964) also used the reward concept in his theory of permanent availability. Heer's(1964) specific application of its concepts to spousal power was among its earliest uses in the family. The general principle or most general proposition of the theory is that humans avoid costly behavior and seek rewarding statuses, to the end maxmize profits. This review will attempt to show that Choice, Exchange theory is applicable to the several arenas of family interaction and that it can provide an explanation for family behavior. Subjects such as mate selection, marital unstability, family cohesion, spousal power, the problems of aged, family co-unseling, and so on are included. By discussing research findings from a perspective of rewrds and costs this review will show that the application of the theory is not limited to one or two substative specialities with in the family domain. After all Choice, Exchange theory is truly general and can be productively applied to any domain of human behavior.

This study was to understand the components that influence preservice elementary teachers' mental models about 'astronomical phenomena' such as the Seasons of the year, and the Lunar Phases of the month. We selected university of education students among whom 23 were in the second you. The data collected from the paper-pencil test and individual interview with students. The results of this study show that the students had apparent synthetic Mental models, and that the distance theory, and occultation theory had most important effects on their Mental Models. It can be said that preservice elementary teachers' initial mental models of the' astronomical phenomenon' have their origin in their belief sets (specific theory) related to 'astronomical phenomenon', on the basis of which they can interpret their observations and cultural information with the constraints of a naive framework of physics. The structures and possible sources of their mental models for overcoming these synthetic mental models were also discussed.
