In the present investigation, by making use of the familiar concept of neighborhoods of analytic and multivalent functions, we prove several inclusion relations associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of analytic functions of complex order, which are introduced here by means of the Al-Oboudi derivative. Several special cases of the main results are mentioned.

In this paper we use uniform cubic spline polynomials to derive some new consistency relations. These relations are then used to develop a numerical method for computing smooth approxi-mations to the solution and its first second as well as third derivatives for a second order boundary value problem. The proesent method out-performs other collocations finite-difference and splines methods of the same order. numerical illustratiosn are provided to demonstrate the practical use of our method.

The US-led and European partners supporting liberal international order has dwindled. A number of research has been conducted to explore reasons, starting point, the possibility of resurrection, and even the future scenarios of the international order. This is particularly important for the EU, in that the EU was built for a world that is peaceful, multilateral and driven by compromise inseparable from the liberal international order. The current situation of the crisis in the international order is also important to emerging powers notably China and Russia which seek for a new order best suitable for their own interests. In this sense, this paper explains the significance of the liberal international order to the EU, the necessity of salvaging an order or creating a new order, and important variables - elections held in 2024 across the EU, in the European Parliament, and the US, Russia's invasion of Ukraine, trans-atlantic partnership and EU-China relations - which possibly affect the EU to establish a new European order. In fact, the EU is unlikely to take the lead in forming a new international order. Nonetheless, the first task the EU should do is to acknowledge the crisis situation at present and to make a decision of the EU's position and role regarding saved, reformed or newly shaped order.

This article will analyze and forecast important variables and dynamics in global power politics after the war in Ukraine. It tries to use several perspectives to analyze international relations, particularly liberal internationalism and structural realism. In short, core variables are as follows; First, how is the US-led liberal international order and globalization being adjusted? Second, how will the U.S.-China strategic competition, which is the biggest and structural variable, cause changes in the international order in the future? The third variable, how stable are Sino-Russia relations in the context of a structuring U.S.-China-Russia strategic new triangle? Fourth, to what extent will third middle hedging states outside the U.S. and China be able to exercise strategic autonomy in the face of multipolarization? To summarize, the first of these four variables is the largest basic variable at the global political and economic level in terms of its impact on the international community, and it has been led by the United States. The second variable, in terms of actors, seems to be the most influential structural variable in global competition, and the US-China strategic competition is likely to be a long game. Thus the world will not be able to escape the influence of the competition between the two global powers. For South Korea, this second variable is probably the biggest external variable and dilemma. The third variable, the stability of Sino-Russia relations, determines balance of global power in the 21st century. The U.S.-China-Russia strategic new triangle, as seen in the current war in Ukraine, will operate as the greatest power variable in not only global power competition but also changes in the international order. Just as the U.S. is eager for a Sino-Russia fragmentation strategy, such as a Tito-style wedge policy to manage balance of power in the early years of the Cold War, it needs a reverse Kissinger strategy to reset the U.S.-Russia relationship, in order to push for a Sino-Russia splitting in the 21st century. But with the war in Ukraine, it seems that this fragmentation strategy has already been broken. In the context of Northeast Asia, whether or not the stability of Sino-Russia relations depends not only on the United States, but also on the Korean Peninsula. Finally, the fourth variable is a dependent variable that emerged as a result of the interaction of the above three variables, but simultaneously it remains to be seen that this variable is likely to act as the most dynamic and independent variable that can promote multilateralism, multipolarization, and pan-regionalism of the global international community in the future. Taking into account these four variables together, we can make an outlook on the change in the international order.

Purpose: This study was conducted to explore experiences of the development of parent-child relations among Korean college students. Methods: The participants were 18 Korean college students. Data were collected through in-depth interviews, and the main question was, "Could you tell me about how your relationship with your parents has developed?". Data were analyzed using Strauss and Corbin's grounded theory methodology. Results: The central phenomena of the experiences of parent-child relations among Korean college students were 'new realizations about parent-child relations' and 'competing against parents'. The major action/interaction strategies were 'having an equal status to one's parents' and 'keeping parents at a distance'. Consequences included 'going beyond the bounds of parental guidance'. Conclusion: These findings indicate that students tried to give back to their parents, and also endeavored to stand apart from their parents in order to obtain independence. Their efforts were influenced by their parents' efforts to be tolerant towards their children. The findings emphasize that Korean college students experienced the process of building new, interdependent relations with their parents.

Guanxi could be regarded as communities based on blood, regionalism, school ties centering on individual person. It has been used as a means of personal interests security and acquisition. What is more, it has formed a mode of socio-economic order, which is an inter-obligation relations based on mutual benefits. In practice, it is necessary to understand and accept guanxi in China, as it is a key factor to understand consumer patterns, inter-firm relations and extra-firm relations between firm and government. In this context, the main aim of the reserach is to identify the impact of guanxi on the business activities of Korean foreign direct investment firms in China by investigating their networks based on guanxi.

This study is to be used for research material for pastoral counseling, by analyzing grounded-theoretically how substance abusers' awareness of self and experience of relations affects problems in abusing drugs. The subject of this study was chosen as 9 prisoners who were able to participate in group counseling, among those who were in prison for substance abuse and had more than 6 months of penal servitude left. In addition, in order to indicate counseling research methods through this study, 12 group counselings were carried out during October 24th. 2002 and February 14th. 2003 and verbatim were written out to be used as original material. After the research material was analyzed, they could be categorized into 60 concepts on the whole from 'conflict' and 'constraining thinking' to 'rationalization' and 'avoidance'. When these concepts were organized into groups of similarity, there were all together 20 categories. From this study, it can be found that substance abusers had "problems about self" and "problems about relations". The factor which affected their use of drugs was the area of relations, where as henceforth their use of drugs, the situation in which they could not escape from the use of substances was affected by problems within the area of self. When facing such problems as substance abuse, the pastoral counselor must create a holding environment through counseling, and perform good enough mothering by being insightful and providing active support on the problem. They must also help one's growth into "an empathizing self", "an accepting self", "a trusting self", "a hopeful self", who can empathize, accept, trust and hope, through experience in separation from the problem, conversion, meta-communication, self-rumination, relations and inspiration of hope. Likewise, the church must be able to act as a "place of growth and skill" which aids in the forming of relations and helps to be aware of self through experience in, and understanding of, relations.

In order to perform the spatial buckling analysis of the curved beam element with nonsymmetric thin-walled cross section, exact static stiffness matrices are evaluated using equilibrium equations and force-deformation relations. Contrary to evaluation procedures of dynamic stiffness matrices, 14 displacement parameters are introduced when transforming the four order simultaneous differential equations to the first order differential equations and 2 displacement parameters among these displacements are integrated in advance. Thus non-homogeneous simultaneous differential equations are obtained with respect to the remaining 8 displacement parameters. For general solution of these equations, the method of undetermined parameters is applied and a generalized linear eigenvalue problem and a system of linear algebraic equations with complex matrices are solved with respect to 12 displacement parameters. Resultantly displacement functions are exactly derived and exact static stiffness matrices are determined using member force-displacement relations. The buckling loads are evaluated and compared with analytic solutions or results by ABAQUS's shell element.
