This study has two purposes. One is to systematize a number of referents and to examine the types of comparisons. The other is to examine categories of comparative standards such as inputs in equity theory. In pay comparison process, referents and inputs are very important elements. The first factor analysis is related to referents, which include 18 variables in 6 categories were subjected to factor analysis. 3 factors emerge with an eigenvalue of 1.0 or greater. Factor I, economic need, includes referents in personal worth and system referent. Factor II, market comparison, includes internal and external referents except one variable(external-peer). Between internal and external referents is not distinguished. This result is corresponded with Hills'(1980) and Hong's(1995) findings. FactorIII is named 'historical/social comparisons'. 14 inputs are subjected to the second factor analysis. 3 factors emerge with an eigenvalue of 1.0 or greater. The 5 variables loading on factor I, equity standard, are responsibility, competency, effort, outcome, and skill. FactorII, equality standard, includes age, gender, and education. FactorIII, seniority standard, includes career and company tenure. All the factors are positively associated with each other. Especially, personal worth is associated with equity standard(r=0.50466). Internal and external referents are associated with any comparative standard.

Net pressures on roofs and walls of buildings are dependent on the internal and external pressure fluctuations. The variation of internal and external pressures are influenced by the size and location of the openings. The correlation of external and internal pressure influences the net pressures acting on cladding on different parts of the roof and walls. The peak internal and peak external pressures do not occur simultaneously, therefore, a reduction can be applied to the peak internal and external pressures to obtain a peak net pressure for cladding design. A 1:200 scale wind tunnel model study was conducted to determine the correlations of external and internal pressures and effective reduction to net pressures (i.e., net pressure factors, F_C) for roof and wall cladding. The results show that external and internal pressures on the windward roof and wall edges are well correlated. The largest ${\mathcal{C}}_{{\check{p},net}$, highest correlation coefficient and the highest F_C are obtained for different wind directions within 90° ≤ θ ≤ 135°, where the large openings are on the windward wall. The study also gives net pressure factors F_C for areas on the roof and wall cladding for nominally sealed buildings and the buildings with a large windward wall opening. These factors indicate that a 5% to 10% reduction to the action combination factor, K_C specified in AS/NZS 1170.2(2011) is possible for some critical design scenarios.

In this paper, a method of increasing in load-carrying capacity is shown in two-span steel-concrete composite bridges strengthened by external tendons. An analytic expression for the increment of tendon force under external loads is derived using virtual work method for straight external tendons and a new rating factor equation is proposed. Considering the initial tendon force and its increment under external loads, an analytic procedure has been developed to calculate the number of tendons and the initial tendon force from the proposed rating factor equation. This method is used to verify a validity and rationality for an existing two-span composite steel-concrete bridge.

This study is to explore the effects of business environment upon corporate image. Customers of foodservice establishments are selected as a population and six famous family restaurants located in Seoul were selected to evaluate the population. Accordingly, the purpose of the study is to survey satisfaction with corporate image of foodservice establishments and six famous family restaurants, to evaluate the satisfaction with corporate image, and to find a plan of raising corporate image. 240 samples were distributed and 194 samples were collected among them. 182 valid samples were selected for the research. As a result of factor analysis for business environment, internal environment factor, external environment factor, addition environment factor were extracted. There was no significant difference by sen, age, schooling, occupation, average income by month, and number of visiting foodservice establishments after examining the difference of establishment business environment by demographic characteristics. Analysing the effects of business environment upon corporate image revealed that the effects of business environment had effects upon corporate image in order of internal environment factor(.531), external environment factor(.360), and addition environment factor(.285).

In this research, the dynamic stability of an orthotropic elastic conical shell, with elasticity moduli and density varying in the thickness direction, subject to a uniform external pressure which is a power function of time, has been studied. After giving the fundamental relations, the dynamic stability and compatibility equations of a nonhomogeneous elastic orthotropic conical shell, subject to a uniform external pressure, have been derived. Applying Galerkin's method, these equations have been transformed to a pair of time dependent differential equations with variable coefficients. These differential equations are solved using the method given by Sachenkov and Baktieva (1978). Thus, general formulas have been obtained for the dynamic and static critical external pressures and the pertinent wave numbers, critical time, critical pressure impulse and dynamic factor. Finally, carrying out some computations, the effects of the nonhomogeneity, the loading speed, the variation of the semi-vertex angle and the power of time in the external pressure expression on the critical parameters have been studied.

The purpose of the research is analyzing how the emotional factors of the external apartment design can be influenced by the consumers' emotional reaction, and analyzing how the emotional reaction of the consumers will affect the expenditure of the apartment in the upcoming future. For this purpose, first, external surrounding factors of the apartment are extracted and then classified into three major design categories (instinctive, behavioral, and reflective design), and each factor is evaluated by the emotional evaluation. The scope of the research is restricted to the apartments in Daegu city which are built by Top 3 construction companies from the analysis of construction-working rank (May, 2010). The residential-expenditure data are extracted from D-univ. students, in accordance with the satisfaction of the external surroundings and emotional-reaction against the emotional-design factors of the apartment. This research is done by the statistic analysis program SPSS17.0. This shows that difference of emotional design by the apartment external space requisites will be significance as fundamental data for development of application and planning and apartment external space of emotional design by the apartment external space in the future.

A method to determine the initial force of external tendon is proposed to improve the load carrying capacity in existing steel-concrete composite bridges. This method is applied to tensioning external tendons prior to and after concrete replacement for strengthening composite girders. A procedure to determine the number of tendon and initial tendon force is described with the proposed rating factor, which considers the increment of tendon force due to live loads. The method is applied to the improvement of rating factor in an existing composite bridge and its validity is confirmed.

The purpose of this study is to measure IPA(Importance Performance Analysis) of the hospital choice factors between internal and external customers at rural general hospital. This study was used 5 types of choice factor such as physical, human, accessibility, connection, and external image. Also, this study was used IPA which can be applied to identify the strengths and weaknesses quality attributes from customers' viewpoint by simultaneously evaluating importance and performance. IPA was assessed using a sample of 98 patients and 96 internal employees who work at C general hospital in Chunkcheongbuk-do. Data were collected with self-administered questionnaires from February 13 to March 30 in 2012 and analyzed SPSS 18 by using frequency, paired t-test and scatter plot graph. The results of IPA show that "Keep up the good work" quadrant was human factor and "Low Priority" quadrant was physical and connection factors between internal and external customers. The finding of this study will be applied to improve human service quality in administrative department of hospital. Also, this study presents primary data for correct decision making to authorities of local hospitals that have concern about hospital strategy. The implications of this study are discussed and areas for future research are presented.
