  • Self-medication is a representative phenomenon in the domain of popular care, originated from perspective of medical pluralism and the pharmacy profession is said to be in the most appropriate position of health care professions to activate self-medication. As any healthcare reform impacts in a country, 2000 institutional separation between medicine and pharmacy implemented in Korea brought a lot of changes in behavior of drug use not only to physicians and pharmacists but also to consumers (patients). In this paper, the reality of self-medication since the institutional separation between medicine and pharmacy was analyzed, based on the empirical data which were collected by the Korea Institute for Health and Social Affairs in 2002. The major finding is that the domain of popular care including self-medication was significantly shrunk, while that of professional care was proportionally expanded. As a result, the following four points were strongly recommended for the purpose of promoting self-medication: i) upgrading the pharmacy education system from 4 year to 6 year level, ii) improvement of continuing education and introduction of GPP (Good Pharmacy Practice), iii) activating 'pharmacal encounter' (i.e., pharmacist-consumer relationship) and iv) promotion of socio-economic research activities and proactive participation in the international self-medication movement of pharmacists in Korea.

  • The time domain simulation method of transient stability presents accuracy and reliability, but it demands much computational time. Therefore it is necessary to filter out very stable and very unstable cases from a large set of contingencies. Following a disturbance, the shape and magnitude of representative generator angle which is most increased after fault clearing are the measure of transient stability. This paper propose a method that is not a calculation of the exact CCT of contingency, but a fast assessment of transient stability. Also it can help operators identify transient stability immediately without analyzing the graphical results. The proposed method is applied to the KEPCO system. The PSS/E is used as a time domain simulation engine by IPLAN.

  • The density approach and the homogenization design method are representative methods in topology optimization problems. In the topology optimization in magnetic fields, those methods are applied based on the results of the applications In elastic fields. In this study, the density method is modified considering the concept of the homogenization design method. Also, the results of the topology optimization in magnetic fields by the modified density method as well as the homogenization method are compared especially focusing the change of the penalization parameter in the density approach. The effect of the definition of the design domain such as global/local design domain is also discussed.

  • It is recognized that the magnetization reverses with a sequence of discrete and jerky jumps, known as the Barkhausen effect. Recently, interest in the Barkhausen effect has grown as it is a good example of dynamical critical behavior, evidenced by experimental observation of a power law distribution of the Barkhausen jump size. So far, most experimental studies have been carried out on bulk samples using a classical inductive technique, which is difficult to apply to thin film samples mainly due to the ]ow signal intensity. For this reason, very few experiments have been done on two-dimensional ferromagnetic thin films. In this talk, we report a direct domain observation of Barkhausen avalanche at criticality in Co and MnAs thin films investigated by means of a magnetooptical microscope magnetometer (MOMM), capable of time-resolved domain observation with an image grabbing rate of 30 frames/s in real time. In Fig. 1, we demonstrate a series of six representative domain-evolution patterns of 25-nm Co film observed successively by means of the MOMM, where one can directly witness Barkhausen avalanche.

  • Multiple sequence alignment is a method to compare two or more DNA or protein sequences. Most of multiple sequence alignment tools rely on pairwise alignment and Smith-Waterman algorithm to generate an alignment hierarchy. Therefore, in the existing multiple alignment method as the number of sequences increases, the runtime increases exponentially. In order to remedy this problem, we adopted a parallel processing suffix tree algorithm that is able to search for common subsequences at one time without pairwise alignment. Also, the cross-matching subsequences triggering inexact-matching among the searched common subsequences might be produced. So, the cross-matching masking process was suggested in this paper. To identify the function of the clusters generated by suffix tree clustering, BLAST and CDD (Conserved Domain Database)search were combined with a clustering tool. Our clustering and annotating tool consists of constructing suffix tree, overlapping common subsequences, clustering gene sequences and annotating gene clusters by BLAST and CDD search. The system was successfully evaluated with 36 gene sequences in the pentose phosphate pathway, clustering 10 clusters, finding out representative common subsequences, and finally identifying functional domains by searching CDD database.

  • Cultural Studies is characterized by being opposed to (elite) literary studies not only because it points to popular or non-elite literature which is usually not dealt with by elite literary scholars or comparatists, but also because it severely challenges the established literary canon and even tries to subvert this elite-oriented canon. In addition, Cultural Studies complements literary studies in that it contributes a great deal to the reconstruction of new literary canon by expanding the narrow domain of (elite) literature and its studies. What was not touched upon by traditional literary scholars is now studied by Cultural Studies scholars. In this sense, we should realize that it is not the field of Cultural Studies that occupies the domain of literary studies, but rather, it has expanded its traditional domain and added some new cultural elements. This article will illustrate how the interdisciplinary writings of some of the representative Anglo-American literary scholars have paved the way for effective dialogues between literary studies and Cultural Studies. I argue that the practice of Cultural Studies in China will not only contribute to global Cultural Studies in general, but also carry on equal dialogue with its Western and international counterparts. My purpose is to deal with the challenge of Cultural Studies to comparative literature studies in general before mapping the new orientations of Cultural Studies in $21^{th}$ century China.

  • Directional emission of light exiting a photonic crystal waveguide by a coherent action of radiative surface modes was recently demonstrated, and subsequently the substantial enhancement of the directional emission was achieved by engineering the surface and adjusting relevant parameters. Here we present the analysis of surface modes causing the enhanced emission by the plane wave expansion method and the finite-difference time-domain method. In particular, surface band structures are calculated for nonradiative and radiative surface modes, respectively, and intensity profiles of some representative modes for nonradiative and radiative cases are given.

  • An anatomical head and a multi-layered spherical head with a half-wave handset antenna have been analysed and compared using the Finite-Difference Time-Domain (FDTD) and the Eigenfuntion Expansion Method (EEM), respectively. The analysis shows that results from a simple spherical head with a half-wave antenna can be used to predict the main antenna radiation patters as well as estimates of the peak SAR in a handset user's head. Various representative design data are presented using a six-layered spherical head with a half-wave antenna at 900 MHz

  • Trichloroethylene, which is one of the representative DNAPL, has been found in underground water sources as a result of the manufactural use, and disposal of the chemical. In this research, in situ air sparging method was chosen to reduce the TCE concentration from the source zone. The concentration reduction in the source zone resulting from air sparging is simulated using the modified STOMP Water-Air operational mode in a two dimensional axisymmetric domain and bench scale test is conducted to analyze the performance of air sparging. The results of laboratory tests are compared with numerical simulations.
