This study investigates the relative effect of symmetric and asymmetric relationship between franchiser and franchisee on the relational outcome of franchise alliance in education industry. To verify the research model, 240 samples, which is related with eduction service, were collected, among which 200 were used for the analysis. The outcome suggests that the asymmetric relationship in an alliance negatively influenced the relational quality, among which asymmetric alliance-specific investments had the most significant effect. On the other hand, the relational quality was positively influenced when the alliance relationship was symmetric, especially when the interactional fairness was high. Furthermore, compared to foreign franchise, local franchise presented higher level of role and responsibility imbalance, along with higher likihood of franchisees' opportunistic behaviors.

It is very important to understand the domain structures of ferroelectric BaTiO3 in the poling process. Especially because {111} twinning is frequently observed in most BaTiO3 ceramics it is required to know the relations between the ferroelectric domains and the structural twin. In this study the domain structures of a {111} twinned crystal sample were observed under a polarizing microscope. and the relation between the {111} twin and the domain configurations could be classified into two types of 'V'-shape and linear shape penetrating perpendicular to the twin boundary. Domain formation obeys the symmetry of the {111} twining when a new domain structure is developed by heat treatment and surface deformation due to domain formation is also occured symmetrically between the both sides of the{111} twin boundary. This symmetrical behavior of the domains could be interpreted with the "head-to-tall" orientation of the domains across the {111} twin boundary.

주식과 부동산은 각각 금융자산(financial asset)과 실물자산(real asset)의 대표 격으로 투자자들에게 매력적인 투자대상이다. 투자자들은 경제 여건의 변화에 따라 나타나는 두 자산의 수익률 차이를 최대한 이용하려고 노력해 왔다. 흔히들 주가와 지가는 서로 대칭적인 것으로 주가가 오르면 지가가 떨어지고, 지가가 오르면 부동산 시장으로 자금이 몰려서 주가가 떨어지는 것으로 얘기하는 경우가 많으나, 실제로는 동행관계로서 완급차이가 있을 뿐이다. 경기변동 곡선을 따라 경기변동에 민감한 주가가 우선적으로 반응하고 뒤이어 지가가 1년여의 시차를 두고 비슷한 패턴을 보이고 있다. 지금까지 대부분의 논문은 지가결정 모형을 세우기 위한 것으로 주가 이외에도 다른 여러 독립 변수들이 지가에 어떤 영향을 주는지를 연구하였다. 지가가 종속변수로서 여러 가지 실물 경기의 상황에 영향을 받는 것처럼 주가도 역시 다른 경기지표의 영향을 받는다. 그러므로 본 연구의 목적은 과거 30여년간의 우리나라 주가와 지가의 움직임을 통하여 주가와 지가 사이의 인과관계를 규명하는데 있다. 즉 주가와 지가 사이에 일방적인 인과관계가 있어서 주가가 지가에 선행하는지, 혹은 주가와 지가 사이에 상호적인 인과관계가 있는지 실증적인 연구를 통하여 알아보고자 한다.

본 연구는 친족관계의 전반적 현황과 양계화 정도를 살펴봄으로써 친족관계 영역에서 변화하는 한국가족의 현주소에 대한 정보를 제공하고자 하였다. 이를 위해 본 연구는 전국의 성인남녀 1755명을 대상으로, 본인 및 배우자 부모와의 동거여부, 거주근접성, 접촉빈도를 비교함으로써 세대관계의 구조적 차원에서 양계화가 어느 정도 이루어졌는지 살펴보았다. 또한, 양계화 정도의 구체적 내용 파악을 위하여 가족의 협력 네트워크의 양상을 조사하였다. 즉 경제적, 도구적, 정서적 지원 영역에서 도움을 주고받는 대상에 대한 조사를 통하여 가족의 지원망 구성 및 활용에 있어 친족이 차지하는 비중 및 양계성의 정도를 살펴보았다. 연구 결과, 첫째, 한국가족의 세대관계의 구조적 특성은 양계화된 모습과 부계적인 모습이 혼재되어있는 것으로 나타났다. 둘째, 가족의 협력네트워크 활용의 측면에서, 한국가족은 부계친족 및 모계친족과의 상호작용이 균형적으로 이루어지는 대칭적 양계화라기보다는 비대칭적 성격의 양계화 경향을 보였다. 이것은 부계중심적으로 규범화된 친족유대의 경향이 그대로 유지되면서 동시에 실제적 필요에 의한 아내의 친족망 활용정도가 높아진데서 기인한 결과라 할 수 있다. 이러한 결과는 한국사회의 빠른 변화에도 불구하고 가족영역에서의 변화가 상당히 느리게 진행되고 있음을 반영한다.

Based on Lagrange's general theory of algebraic equations, by applying the solution of the equation using the relationship between roots and coefficients to the high school 1st grade class, the purpose of this study is to recognize the significance of symmetry associated with the solution of the equation. Symmetry is the core idea of Lagrange's general theory of algebraic equations, and the relationship between roots and coefficients is an important means in the solution. Through the lesson, students recognized the significance of learning about the relationship between roots and coefficients, and understanded the idea of symmetry and were interested in new solutions. These studies gives not only the local experience of solutions of the equations dealing in school mathematics, but the systematics experience of general theory of algebraic equations by the didactical organization, and should be understood the connections between knowledges related to the solutions of the equation in a viewpoint of the mathematical history.

Purpose Metabolic abnormalities in hepatic encephalopathy (HE) cause brain edema or demyelinating disease, resulting in symmetric regional cerebral edema (SRCE) on MRI. This study aimed to investigate the usefulness of the clustering analysis of SRCE in predicting the development of brain failure. Materials and Methods MR findings and clinical data of 98 consecutive patients with HE were retrospectively analyzed. The correlation between the 12 regions of SRCE was calculated using the phi (φ) coefficient, and the pattern was classified using hierarchical clustering using the φ² distance measure and Ward's method. The classified patterns of SRCE were correlated with clinical parameters such as the model for end-stage liver disease (MELD) score and HE grade. Results Significant associations were found between 22 pairs of regions of interest, including the red nucleus and corpus callosum (φ = 0.81, p < 0.001), crus cerebri and red nucleus (φ = 0.72, p < 0.001), and red nucleus and dentate nucleus (φ = 0.66, p < 0.001). After hierarchical clustering, 24 cases were classified into Group I, 35 into Group II, and 39 into Group III. Group III had a higher MELD score (p = 0.04) and HE grade (p = 0.002) than Group I. Conclusion Our study demonstrates that the SRCE patterns can be useful in predicting hepatic preservation and the occurrence of cerebral failure in HE.

Mamoru Hosoda's (2015) depicts the adventure with which a physically and psychologically isolated boy is growing through a 'Relationship' with surrounding beings. This paper intends to reveal the essence of 'Relationships' and 'True Growth' that the director presents to us. In the film, a boy's adventure is centered on two worlds (the human world and the beast world). Here, the human world refers to a civilized society, and the beast world 'Naturalness' as the inner nature of a human being. The human world and the beast world in the mirror-relationship with the human world were originally a world, and the inside and the outside of the place for all existing things were connected in one. Human beings were never superior to the surrounding beings, but all beings were equal in relationship. The way of thinking in that age is called 'Symmetrical Thinking.' But as human beings opened the road to self-centered civilization, they eliminated 'Nature' inside themselves. As a result, the two worlds (human beings and nature, or the human world and the beast world) were eventually separated. This destroyed not only the human-nature relationship but also the human-to-human relationship, which is one of the characteristics of the civilized society where we currently live. Through the boy's question, "Who am I?", the director suggests to us that the inner nature of a human being as a natural being should be reinstated. This means that a human being restores the "relationship" with all beings (other beings) surrounding himself or herself, which is the only alternative to overcome various violences of the civilized society that we have created. The full growth of a human being is achieved at this point. In this way, offers a reflection on the human civilization and society, and questions the possibility of coexistence with other beings, through cosmic thinking (symmetrical thinking) that we have lost. In this respect, it is a text presented as a 'Model of Maturity' for an immature human society.

The universality of the quasi-linear relation between the order parameter S and the normalized birefringence ${\Delta}n_{rel}$, $S=(1+a){\Delta}n_{rel}-a{\Delta}n^2_{rel}$ is confirmed. It is verified that the refractive index of liquid crystals distributed with regular polyhedral symmetry is isotropic and it is given as $\frac{1}{n^2_{av}}=\frac{1}{3}\(\frac{1}{n^2_e}+\frac{2}{n^2_o}\){\cdot}S$ and ${\Delta}n_{rel}$ of angular weighted liquid crystals that are initially distributed with regular polyhedral symmetry, are numerically calculated. Also ${\Delta}n_{rel}$ and S of liquid crystals that are conically distributed, keeping the rotational symmetry about z-axis are calculated as the apex angle of the cone is varied. Based on these calculated results, it is confirmed that the quasi-linear relation between S and ${\Delta}n_{rel}$ is universal, independent of the details of the distribution function.
