An in vitro study was performed in order to evaluate the restoring methods in the endodontically treated molar teeth. 68 extracted teeth were divided into 4 groups according to the restoring techniques. The teeth of first group were restored by amalgam. Those of second group were restored by the stainless steel post and amalgam. The teeth of the third group were restored by the amalgam with crown. The teeth of the fourth group were restored by the stainless steel post and amalgam core with crown. All the specimens were tested and measured for the fracture load by means of the Instron (UTM-111-500 Toyo Baldwin Co., LTD. Japan) and the Pressure Instrument (Yonsei University, Department of Metal Engineering.) The results were as follows; 1. There were no statistical differences in the fracture loads between the amalgam restoration and post-amalgam core restorative techniques. 2. The techniques of amalgam core with crown showed lower fracture loads those of post and amalgam core with crown. 3. In the crowned teeth, they presented higher fracture loads than those without crown.

In this study, in order to clarify the effect of the direction of cyclic shear on the post-earthquake settlement the multi-directional shear tests were carried out for Toyoura Japan standard sand, Genkai natural sand and the Granulated Blast Furnace Slag (GBFS). In a series of tests, number of strain cycles was changed as n=5-200 and the shear strain amplitude varied from 0.1% to 1.0%. The relative density was also changed as Dr=50, 60 and 70%. From the test results for Toyoura sand and GBFS, it is clarified that the post cyclic settlement is relatively large at the small relative density and becomes large with the shear strain amplitude. When the influence of the direction of cyclic shear is decreases, the post cyclic settlement strain for Toyoura sand is converged to a constant value, but the GBFS is increased with the number of strain cycles.

Wii^® balance board (WBB, Nintendo, Japan) is a device that can measure and record the center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) in relation to body sway. For evaluating measure of improvement after reconstruction of medial patellar luxation (MPL) in small sized dogs, A total of 6 dogs with limping and lameness gait attributed to Grade II, III or IV MPL were evaluated. Dogs were measured for difference of extension and flexion range of motion in the stifle (dROM), muscle mass, lameness, willingness to bear weight on the affected limb while standing, and willingness to lift the contralateral limb scores, CPPL and Area 95 of WBB on pre-surgery, post-surgery 4, 8 weeks. CPPL was significantly different on pre-surgery compared with post-surgery 8 weeks (p < 0.05). Except for CPPL, measured variables were significantly different on pre-surgery compared with post-surgery 4 and post-surgery 8 weeks (p < 0.01).

This study examines the post-national trends of the $21^{st}$ century fashion that has embraced multiculturalism. This study conducted a literature view to explore the concept of multiculturalism and the background of post-national phenomena appearing in contemporary fashion. In addition, as a case study, the author used local and foreign fashion magazines and collections published between 2000 and 2009, in addition to other related materials available on the Internet. The objective was to analyze photographic materials in which post-national features are reflected. From this study, the post-national trends in $21^{st}$ century fashion that adopted multiculturalism are as follows: The first is that oriental culture is more actively embraced. In the past, the tendency of embracing the oriental culture was mainly developed with a focus on China and Japan, but recently the tendency has spread to Southeast Asian countries and national/ethnic minorities that include Mongolians and Tibetans that is present in more active ways that reflect oriental sentiment and philosophy as well as adopts simple images. Second, $21^{st}$ century fashion based on multiculturalism broadens the interest in the understanding of nations in the regions of Africa, Middle East, and South America and uses regional folk costumes or indigenous characteristics to create new things instead of staying within a fixed paradigm. Third, as horizontal transfer is involved in ways of looking at culture, $21^{st}$ century fashion shows a post-national tendency to use regional cultures and folk costumes of the occidental world that includes North and West Europe in addition to non-mainstream regions (as considered so far). Fourth, dress elements of many heterogeneous national cultures are combined to create multinational images difficult to define in terms of a specific national culture or clothing style.

Ruth Ozeki(Japanese-American female novelist)?s recent novel, A Tale for the Time Being (2013) draws our attention because the fiction shows very interesting fictional experiments, especially in terms of post-humanism. Indeed, the novel is not a science fiction at all which has been, and still is, the typical fictional field employed in the discussion for the transhumanism and posthumanism. It also does not include any cybogs, robots, or aliens which provoke the posthumanism-related issues like mind/body, human/nonhuman, nature/culture relations. Indeed, it seems "merely" represent realistic day-to-day lives of ordinary people living in contemporary Japan and Canada, and in very minute and particular details at that. Indeed, the central action of the main characters of the novel seems very traditional, that is on the one hand writing a diary by a teenage girl who is counting the days and weeks before her suicide and on the other hand reading it by a female novelist who happens to find her diary several years later. Nevertheless, I would like to suggest that underneath this traditional narrative surface are simmering post-humanist and post-anthropocentric worldviews beyond liberal Humanism which takes human beings to be exceptional against human or non-human others. Not only in narrative contents and characterizations but also through narrative structure and strategies, the novel enacts post-humanist and post-anthropocentric worldviews which are interestingly drawn from both age-old Buddhist ideas and modern eco-philosophy and quantum physics. I would like to stress that what triggers the author's fictional experiments helping our rethinking and redefining "what human beings are" and "what the relation between humans and nonhumans" is not merely intellectual interests but her keen and passionate response to the heart-breaking pains and sufferings of human and nonhuman beings caused by the contemporary natural-artificial catastrophes and techno-scientific predicaments.

The World Commission on Dams (WCD) in November 2000 published "Dams and Development" as its only and final report. The report proposed "internationally acceptable criteria and standards" Despite the (act that the WCD itself did not regard the report as a blue print, many NGO's strongly support the report and the guidelines, and demand that they be adopted in their current form by funding organizations. The WCD recommendations and guidelines were found to have several "generic" problems, and the proposed guidelines appear unable to be applied as they stand. The authors assume that only several of these guidelines are operational and many of these are either too experimental or theoretical to be put into use. Furthermore, some seemingly "ready for operation" guidelines still need to be enhanced to be really operational in the real world. About 2,000 large dams were constructed in Japan after the Second World War. Various principles and mechanisms were then developed to better address the issues related to involuntary resettlement. The knowledge accumulated through large dam construction projects in Japan may be applied to other countries. The aim of this paper is to identify the lessons, out of the experiences gained in Japan through large dam construction projects in the past, which could be applicable for future large dam construction projects in other nations. The socio-economic settings as well as legal frameworks in Japan may differ other nation. Nevertheless, the following aspects of the experiences gained in Japan are found to be both applicable and useful for future large dam construction projects abroad: (a) Integrity of community in the negotiation process, (b) Provision of alternative occupations, (c) Funding mechanism in the post-project period, (d) Measures needed during planning process, and (e) Making resettlers "shareholders". These lessons may prove useful to enhance the WCD guidelines.

Objective: To evaluate the safety, feasibility, and efficacy of microwave ablation (MWA) for the treatment of primary hyperparathyroidism (PHPT). Materials and Methods: This study enrolled 67 PHPT patients (22 men, 45 women; mean age, 56.0 ± 16.3 years; range, 18-83 years) from January 2015 to December 2018. The laboratory data, including the serum intact parathyroid hormone (iPTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels, were evaluated before MWA and again 2 hours, 1 day, 7 days, 1 month, 3 months, 6 months, 12 months, 18 months, and 24 months after. Results: Complete ablation was achieved with all 72 hyperplastic parathyroid glands found on the 67 patients enrolled, 64 of whom were treated in one session and 3 were treated over two sessions. The technical success rate was 100%. The median follow-up time was 13.6 months (range, 10.0-31.1 months). The clinical success rate was 89.4%. The volume reduction rate was 79.4% at 6 months. Compared to pre-MWA, the serum iPTH, calcium, phosphorus, and ALP levels had significantly improved 6 months post-MWA (iPTH, 157.3 pg/mL vs. 39.2 pg/mL; calcium, 2.75 ± 0.25 mmol/L vs. 2.34 ± 0.15 mmol/L; phosphorus, 0.86 ± 0.20 mmol/L vs. 1.12 ± 0.22 mmol/L; ALP, 79 U/L vs. 54 U/L, respectively; all, p < 0.01). Hoarseness was a major complication in 4 patients (6.0%), but it improved spontaneously within 2-3 months. Conclusion: MWA is safe, feasible, and effective for the treatment of PHPT.

Drawing on its extensive experience with natural disasters, Japan has been dispatching Japan Disaster Relief (JDR) team to disaster-stricken countries to provide specialist assistance in rescue and medical operations. The JDR team has assisted in the wake of disasters including the 2004 Indian Ocean Earthquake and the 2008 Sichuan Earthquake in China. Information about the affected area is essential for a rapid disaster response. However, it can be difficult to gather information on damages in the immediate post-disaster period. To help overcome this problem, we have built on an Earthquake Damage Estimation System. This system makes it possible to produce distributions of the earthquake's seismic intensity and structural damage based on pre-calculated data such as landform and site amplification factors for Peak Ground Velocity, which are estimated from a Digital Elevation Model, as well as population distribution. The estimation result can be shared with the JDR team and with other international organizations through communications satellite or the Internet, enabling more effective rapid relief operations.

With every Yasukuni Shrine visit by a Japanese Prime Minister, one can expect that the Korean government will jump up and down to condemn Japan. The blatant antagonism between the two powerhouses in Asia, lingering around more than sixty years after the end of the colonial period, is unmistakably more than interplay of their colonial history. It is an illumination of a largely unsettled post-colonial diplomacy that was executed in the name of economic advancement. The purpose of this paper is to shed lights on a largely ignored subject matter that unambiguously shaped the peculiar relationship between Korea and Japan.
