The ownership structure of a franchise system is determined by the franchisor's strategic choice. A close look at the extant theories and perspectives in economics and management such as resource scarcity theory, agency theory, transaction cost analysis, and mixed ownership theory reveals that firms choose their ownership structure for the sake of economic efficiency, profit potentials, the chance of survival, and other strategic concerns. The present study, on the basis of strategic choice perspective, reviews the divergent theories of a franchise system's ownership structure and its determinants, thus providing a theoretical framework for comparing the contradictory arguments along the several critical dimensions. We also developed and tested the conflicting hypotheses regarding key determinants of ownership structure including firm's age, size, transaction-specific investments, uncertainty, and risk-sharing propensity. Using a FDD (Franchise Disclosure Document) data set of 543 Korean franchisors, we found that the years in business, the total number of employees, days of training, the inverse of the years of franchising, and the requirement of royalty payment have positive relationships with the proportion of company-owned outlets to total number of outlets. On the other hand, the proportion of company-owned outlets was found to have negative relationships with the total number of outlets and the extent of geographic dispersion of outlets, but to have no significant relationships with the initial investment required and the inverse of contract length. Based on the findings, we provide several theoretical and managerial implications for studying ownership structure of franchise systems.

When vertical shafts are constructed in soft clay with low strength, there is a risk of basal heave, which causes the excavation surface to heave due to the low bearing capacity of the ground against the imbalance of earth pressure at the excavation surface. Methods of deriving a safety factor have been proposed to evaluate the stability against the basal heave. However, there are limitations in that it is difficult to accurately evaluate the heave stability because many assumptions are included in the theoretical derivation. In this study, assuming that a circular vertical shaft is constructed in soft clay, the existing safety factor equation proposed through a theoretical approach was supplemented. Bearing capacity according to the shaft geometry, inhomogeneity of the soil, and the effect of soil plug were considered theoretically and applied in a previous safety factor equation. A three-dimensional numerical analysis was conducted to simulate the occurrence of basal heave and review the supplemented equation through various case studies. Several series of case studies were conducted targeting various factors affecting heave stability. It was verified that the additionally considered characteristics were properly reflected in the supplemented equation. Furthermore, the effects of each factor constituting the safety factor equation were examined using the results of the numerical analysis performed by simulating various cases. It was confirmed that considering the undrained shear strength increment according to depth had the most significant effect on the calculation of the safety factor.

Soil vapor extraction (SVE) is an effective and cost efficient method of removing volatile organic compounds (VOCs) and petroleum hydrocarbons from unsaturated soils. Incorporating PVDs in an SVE system can extend the effectiveness of SVE to lower permeability soils by shortening the air flow-paths and ultimately expediting contaminant removal. With this approach, the real bounded system is replaced for the purposes of analysis by an imaginary system of infinite areal extent. The boundary conditions for the contaminant remediation model test include constant head and no flow condition. Due to these parallel boundaries conditions, image wells should be developed in order to maintain the condition of no flow across the impermeable boundary. It is also assumed that the flow is drawdown along the constant head boundary condition. The factors contributing to the difference between the theoretical and measured pressure heads were also analyzed. The flow factor increases as the flow rate is increased. The flow rate is the most important factor that affects the difference between the measured and theoretical pressure heads.

이 논문의 목적은 수없이 많은 독일어 동사들 가운데 사람의 심리-감정을 표현하는 동사, 소위 감정동사(Emotionsverben: Verben der Gefuhlsbewegung)를 하나의 어휘-의미장(lexikalisch-semantisches Feld)으로 보고 이들의 통사구조 및 의미구조를 파악하여 결합가 모형화 하는 것이다. 우리는 감정동사의 통사 구조 및 의미구조를 기술하기 위해 동사 중심의 결합가 이론과 격이론을 이론적$\cdot$방법론적 토대로 삼았다. 또한 우리는 감정동사를 보충어의 수와 형태에 따라 크게 세 가지 그룹, 즉 2개의 보충어를 갖는 그룹 I(이 그룹에 속하는 동사들은 무생물(사물)을 주어로 갖는다)과 그룹 II(이 그룹에 속하는 동사들은 유생물(사람)을 주어로 갖는다) 그리고 3개의 보충어를 갖는 그룹 III(사람과 사람간의 관계를 나타낸다)으로 구분하였다. 예증을 위해 개별 동사에 대해 용례를 제시했다. 2개의 보충어를 갖는 그룹 II를 보충어의 수의성 여부에 따라 하위 분류했다. 보충어의 형태는 명사구(Sn, Sd, Sa, Sa)와 전치사구(pS)에 한정했으며 - 지면관계상 개별 동사의 예문으로 제시하진 않았지만 - 문장형태의 보충어, 예를 들어 dass-문장(Nsdass)과 부정사문(Inf)도 고려하여 통사적 문형(syntaktisches Satzmodell)과 의미적문형(semantisches Satzmodell)에서 제시하였다. 결국 이 논문은 독일어를 배우는 이들에게 독일어 동사의 통사구조 및 의미구조를 보다 쉽게 설명할 수 있는 하나의 방법론을 제시함은 물론, 나아가서는 결합가 사전에서 동사 내항 기술을 위한 기본적인 토대를 제공할 것이다

This research is an empirical study on an attributions style of individual economic success based on the attributions theory. I established the title of an empirical study on an attributions style of an individual economic success based on a theoretical analysis and an advanced research of an attributions theory. This paper conducted a survey of 238 adults inhabited in Seoul Metropolitan Area by age and gender sample extraction method for an empirical study. A results on attributions factors of individual economic success, Persons under 1billions won indicated that an individual economic success charged off ingrained environment(72.1%) and efforts(18.0%). Persons over 3 billions won suggested that an individual economic success charged off efforts(48.0%) and ingrained environment(12.0%). A man of few wealth showed that an individual economic success chalked up to an ingrained environment. But wealthy persons demonstrated that an individual economic success charged off an individual efforts by attributions style of cause perception, Weiner(1979).

The purpose of this study was to analysis the characteristics on participation process and meaning of Dancesports participants. The participants could dance both Latin and Modern with more than three years of participation experience. The data analysis was based on open coding, axial coding and selective coding from the grounded theory of Strauss & Corbin(1998). The results of the analysis were as follows; It was found that causal situation have a longing for Dancesports and a means of living, contextual situation indicated perception of potential ability, media, and leisure chance, intervene condition given improvement of interpersonal relationships, bilateral strategies betterment of lesson place and health promotion and others. As results, the participants were able to find out their positive and negative aspects of participating Dancesports classes, and showed that Dancesports provided the participants for vitality of life.

In this paper, vertical earth pressure by CANDE program is compared with that by some equations such as the equation by Janssen, Marston, Spangler, and Handy to calculate vertical earth pressure with respect to several factors acting on a rigid buried-pipe filled cohesionless soil. As a result of comparative analysis of vertical earth pressure with each equation, primary factors are affected by backfill width, backfill depth and wall friction. Moreover, vertical earth pressure is linearly increased with backfill depth and width from results of the finite element method. Handy's Equation is reasonable for finite element method while Marston equation is overestimated in case of the design of buried-pipe and box.

The purpose of this study is to review the advanced researches of the library tour, to extract the educational properties of library tour, and to propose the pedagogical meanings of library tour by reinterpreting the library tour based on pedagogical theories and foundations. As the result of this study, the extracted educational properties of library tour are like these: experience, media, explanation, interpretation, interaction. The educational properties are extracted through the related theories and researches. The pedagogical foundations based on the educational properties of library tour are like these: 1) John Dewey's experience theory. 2) Dale & Dwyer's teaching & learning media theories. 3) Bruner's educational theory. It's expected that this study will help the education librarians to plan, develop, and implement the face to face or virtual library tour program based on the pedagogical foundations for the effective library education.
