In this paper uses Kaname Akamatsu's 'Flying Geese' model to analyse Japan's role in East Asian integration. Japan made the first attempt to lead Asian countries before the Second World War. At that time, the Japanese Government embarked on a brutally expansionist policy the result of which was creation of the first gaggle of 'flying geese' under the name of the 'Greater East Asia Co-Prosperity Sphere.' During the 'flight' Japan was forcefully imposing its own ideals and values on the rest of the 'gaggle.' At the same time, the Japanese Government assumed hostile attitude toward Western countries. Japan's defeat in the Second World War signified the end of flight for the first 'flying geese' gaggle. After the war, Japan made another attempt at regional integration. This time it was done through establishing a production network in East Asia. Thus the second gaggle of 'flying geese' came into existence. During the flight of the 'second gaggle' of geese, Japan was fostering good ties with Western countries as well, especially the United States. However, some leaders of the 'second gaggle's' member-countries emboldened by their countries' economic success proclaimed that future belongs to Asia and put forward the 'Asian values' argument. The Asian economic crisis of 1997 interrupted the flight of the 'second gaggle' and effectively put an end to the 'Asian values' debate. It is interesting to note that some elements of the 'Asian values' argument resembled ultranationalist discourse that had been dominant in Japan before and during the Second World War. This paper compares historical patterns of East Asian regional integration and highlights future challenges for Japan's Asia policy.

China's proposal of the CAFTA (China-ASEAN Free Trade Area) in 2001 prompted a great debate about whether China was a trade competitor of ASEAN, given their similarity in economic development levels and trade/export structures. That Beijing shifted its focus on economic cooperation from the international level to the regional level led to its proposal of the CAFTA. As the Framework Agreement (Framework Agreement on Comprehensive Economic Cooperation between China and ASEAN) showed, Beijing's careful consideration for four newer ASEAN members (Cambodia, Laos, Myanmar and Vietnam) intended not only to help all ASEAN members develop economically, but also to narrow the economic gap existing between them and the six old ASEAN members; in return, China was recognized as a full market economy, which it is not currently recognized within the framework of the WTO. The substantial rise in bilateral trade and the structural changes of the trade in goods between China and ASEAN member nations after 2001 proves that ASEAN benefited more from the CAFTA, particularly when the areas where ASEAN had the comparative advantages were designated as the priority cooperation areas between China and ASEAN. In sum, similarities existing in economic development levels and industrial structures between China and ASEAN made them natural economic competitors. However, closer studies of trade in goods of S1-7, S1-6 and S1-0 reveal that China acted as an increasingly complementary trade partner of ASEAN after 2001.

A ban on political podcasting during the General Elections 2006 in Singapore was justified by the Singaporean government on the grounds that the new medium had a greater power to influence voters than traditional modes of political discourse. A between-subjects controlled experiment was conducted to test whether podcasts of political speeches had a greater power to influence voters' evaluations of political candidates and likelihood of voting for them than online text-based transcripts of the same speeches. The study also examined whether mere exposure to political speeches online, irrespective of the modality, had an effect on voters' more general political preferences, i.e. the likelihood of support and voting for the opposition. The findings suggest that political podcasts were no more persuasive than text-based websites and that the effects on political preferences, if any, were likely due the exposure to political content online, not because of the nature of the medium. The implications of the findings are discussed.

In this study, a part of the social and the economic condition of Nepali women is introduced with a short comparison to the socio-cultural position of the women of Korea. A relative definition of the condition of the past and now: this also briefly introduces the ideas of some of the Nepali women that we have collected through the questionnaire. A comparative literature reviews about the position of women in the past as well as the review of the position of women in present is made. Various articles are used for this as the method of analysis. A quantitative analysis of the status of women (Nepal) taking 24 households through the questionnaire method was done. The answers given by the women are the base for the article. However, the answers to the questionnaire are used to compare the past and the present. Analysis of the received data and their explanation through the tables and graph are done. The charts and tables are followed by a detailed explanation. Conclusively the briefing of the condition of women in both the countries, the changes that are brought or not brought by development; in their life's status and position in society, is mentioned.

Background: Dermoid cysts of the auricular area are extremely rare. We report on six cases of auricular dermoid and epidermoid cyst, and differentiate dermoid cyst from epidermal cyst along with a review of the literature. Methods: Three cases involved a gradually enlarging mass of the superior and anterior aspect of the helix of their ear. Another two cases were located in the posterior aspect of the ear. Results: During the operation, a tumor was found just under the skin, not fixed mastoid or adjacent cartilage. Histologically, all specimens contained desquamated squamous epithelium and keratin in the lumen. However, two cases of posterior masses showed the presence of adnexal structures and three cases did not. Conclusion: A key in diagnosis of the dermoid cyst is the presence of adnexal structures. If the wall does not bear adnexal structures, the term epidermoid or keratin cyst is applied. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Finally, the congenital epidermoid cyst grew at the upper part of the auricle; however, the dermoid cyst grew at the lower and posterior part of the auricle.

Apolipoprotein B-100 (Apo-B100) is a major protein component for low density lipoproteins (LDL). A number of mimetic peptides of Apo-B100 were screened from the phase-displayed random peptide library by utilizing monoclonal antibody (B9). Mimetic peptide for B9 epitope against apo B-100 was CRNVPPIFNDVYWIAF (pB1). From the BLAST search, the mimetic peptide pB1 had 40% homology with apo B-100. As a result of the structural determination of this mimotope using homo/hetero nuclear 2D-NMR techniques and NMR-based distance geometry (DG)/molecular dynamic (MD) computations, DG structure had low penalty value of 0.3-0.6 ${\AA}^2$ and the total RMSD was 0.5-1.5 ${\AA}. Moreover, pB1 structure included a weak $3_{10}$-helix from $Ile^7$,/TEX> to $Trp^{13}$.

C-terminal fragments of APP (APP-CTs), that contain A$\beta$ sequence, are found in neurotic plaques, neurofibrillary tangles and the cytosol of lymphoblastoid cells obtained from AD patients. CT26, Thr639-Asp664 (TVIVITLVMLKKKQYTSIHH GVVEVD) includes not only the transmembrane domain but also the cytoplasmic domain of APP. This sequence is produced from cleavage of APP by caspase and $\gamma$-secretase. In this study, the solution structure of CT26 was investigated using NMR spectroscopy and circular dichroism (CD) spectropolarimeter in various membrane-mimicking environments. According to CD spectra and the tertiary structure of CT26 determined in TFE-containing aqueous solution, CT26 has an α-helical structure from $Val^{2}\;to\;Lys^{11}$ in TFE-containing aqueous solution. However, according to CD data, CT26 adopts a $\beta$-sheet structure in the SDS micelles and DPC micelles. This result implies that CT26 may have a conformational transition between $\alpha$-helix and $\beta$-sheet structure. This study may provide an insight into the conformational basis of the pathological activity of the C-terminal fragments of APP in the model membrane.

The Arabidopsis thaliana S-Adenosylmethionine decarboxylase (AdoMetDC) cDNA ($GenBank^{TM}$ U63633) was cloned. Site-specific mutagenesis was performed to introduce mutations at the conserved cysteine $Cys^{50}$, $Cys^{83}$, and $Cys^{230}$, and $lys^{81}$ residues. In accordance with the human AdoMetDC, the C50A and C230A mutagenesis had minimal effect on catalytic activity, which was further supported by DTNB-mediated inactivation and reactivation. However, unlike the human AdoMetDC, the $Cys^{50}$ and $Cys^{230}$ mutants were much more thermally unstable than the wild type and other mutant AdoMetDC, suggesting the structural significance of cysteines. Furthermore, according to a circular dichroism spectrum analysis, the $Cys^{50}$ and $Cys^{230}$ mutants show a higher a-helix content and lower coiled-coil content when compared to that of wild type and the other mutant AdoMetDC. Also, the three-dimensional structure of Arabidopsis thaliana AdoMetDC could further support all of the data presented here. Summarily, we suggest that the $Cys^{50}$ and $Cys^{230}$ residues are structurally important.

This study describes the geometric characteristics and the 5-axis machining method in order to make end mill cutter coming with insert tips. End mill geometry is consisted of flute part and insert tip part. Flute part modeled by using ruled surfaces with constant helix angle, and insert tip part modeled by rectangular planes containing tapped hole of specified direction in its center. In this study, the modeled insert tip part considered both of a radial rake angle and a axial rake angle, because they were important cutting conditions. In order to machining the virtual end mill defined from geometric characteristics, we programmed a special software to machining the end mill considered in this study. This software can generate NC-codes about following processes, end milling or ball end milling of flute part end milling of rectangular plane, centering of hole, drilling of hole, and tapping of hole. Ant sampled end mills were modeled and machined on 5-axis CNC machining center with two index tables. Since machined end mills were very agreeable to designed end mills, we saw that the method proposed in this study can be very useful for manufacturing of end mill body with insert tip.
