  • The magnetic anisotropy of amorphous wires plays a decisive role in the giant magnetoimpedance(GMI) behavior. The magnetoelastic anisotropy caused by internal stress, that are frozen in during the fabrication process, results in an axial easy axis in the core region and in a circular easy axis in the shell region [1]. It leads to a simple domain structure consisting of circular domains in the shell and axial domains in the core. For a more realistic domain structure, it has been suggested that the helical anisotropy exists due to an internal helical stress [2]. (omitted)

  • Objective: To improve customer satisfaction through accurate information using computerized automation of the test reservation system and by performing all fasting tests on the same day with one fasting. Methods: Quality improvement activities of the test reservation system of Seoul National University Bundang Hospital improves internal and external customer satisfaction at the time of test scheduling by having the reservation system reflect test order and test time automatically and making the system to increase the same day test reservation rate. Results: Test process was smooth due to accurate test reservation and information based on test priority due to the introduction of the computerized test reservation system. Internal and external customer satisfaction improved due to the marked reduction in time required for making a reservation thanks to the improvement of work process. Conclusion: Building a computerized test reservation system was an effective measure to improve external and internal customer satisfaction.

  • This study has been implemented under the two purposes. One is to critically explore how married immigrant women had experienced or experience conflicts, differentiation and so on occurred in their relations to family, neighbor, friend, organization and nation. The other is to understand married immigrant women and family through a new perspective based on a relational space of interacting trans-nation, local and nation. The results of the study are summarized as the followings. Firstly, transnational space is produced by international marriage between Korean man and foreign woman and kept (or activated ) by (non) everyday activities of married immigrant women and family. There are remittance, children's rearing and education, visits to mother's house, emotional interactions by phone and computer and so on. Secondly, multi-layered and relational local spaces have been (re)produced by married immigrant women's various activities related to family, neighbor, friend, nation and so on. Thirdly, married immigrant women's relations to nation state or government has been specifically presented (or expressed) through the acquiring of Korean nationality and government's activities of supporting multicultural family. Married immigrant women feel that their national identity between mother's nation and Korea is ambiguous and undecided.

  • Platinum (Pt) nanoparticles were prepared by the liquid-phase reduction of tetraammineplatinum (II) chloride $([Pt(NH_3)_4]Cl_2)$ using Nafion as a stabilizer under various conditions of the Nation phase. This method is novel in its use of electrostatic interactions between the Pt complex ions and sulfonic groups in the hydrated Nation molecules. The synthesized Pt nanoparticles of the recast film system had a cubic shape. In the case of the Nation solution system, the Pt nanoparticles mainly had a spherical shape. The shapes and sizes of the Pt nanoparticles were strongly influenced by the Nation phase.

  • This paper investigates a high performance converter topology for hydrogen gas generation electrolysis system. The proposed converter topology consists of full-bridge inverter, medium frequency transformer, and diode rectifier. Hydrogen gas generation electrolysis process considered in the paper is analyzed and characterized by its equivalent circuit. The electrolysis cell is modeled as effective resistance, capacitance, inductance, and internal emf voltage source. The proposed converter topology provides enhanced efficiency of hydrogen gas generation process under the operating condition of dc output voltage with high frequency ripple on it. The high performance operation of proposed converter is confirmed through the simulation with the electrolysis cell considered in the equivalent circuit model.

  • In this study, a model was developed to analyze the capacity and the total price of the agricultural products marketing between nations through the estimation of the production and consumption amount of the agricultural products in each nation and the analysis of the price and transport cost to each nation. The method which can contribute to the agricultural policy decision support was devised. The main concept of the method is to compute the potential import-export amount and total cost among the nations. In the application, wheat was selected to evaluate the model. The application results showed that the model could analyzed the unit consumption and storage amount per capital of each nation and the price and transport cost per unit weight from each export nation, provided the policy decision maker with the basic data analyzed by GIS.

  • It seems that there has been a tendency of faction film which reveals imagination of state/nation. As typical examples, & would show the relationship between some factional imagination and the project of blockbuster. In this regard, I've researched the tradition of cinematic representation of state/nation and some historical aspects which reveal the being of official films ruled by oppressive political intention. As a kind of discourse dealing with state/nation, & have specific strategy of representation. The analysis about that process might enable us to understand what is nationalism and what is the nature of ideological discourse consumed by faction-related products.
