This study aims to explore a possibility of implementation of “Service-Learning” program into the Korean University curriculum. To do so, the author took some Korean university students to Malaysia and organized a volunteer project in July 2009. In the middle of the project, the participants were asked for producing their “reflection paper” and drew what impressed them the most during the stay. The data collected has been categorized into three different groups such as positive descriptions, negative descriptions and others, and analysed in order to find the experiences which made impacts on them. It allows authors to find the ones led them to some rare overseas “learning experiences”. On top of that, some descriptions, which are able to connect with a reparation program as well as a post-session evaluation program for the next project. It can be said that the result may illuminate the possibility of implementation of Service-Learning program into the Korean university curriculum.

内側を向く日本の若者

山下大輔(Yamashita Daisuke) 동아시아일본학회 2011 일본문화연구 Vol.39 No.-

A lot of mass-medias have discussed the tendency of insuring among the young people in Japan these days. This article explores the level of this phenomenon in the 2nd year engineering students of a state university near Tokyo. The research consists of two different parts. The first part employs a set of questioners, which ask theire xperience of travelling outside Japan and the future possibilities of working for Japanese companies and non-Japanese companies in Japan as well as the ones outside Japan. The second part is the text analys on their writing after my lesson, which introduced the case of a Korean university and my own experience in Africa. This research reveals that the students in the university are extremely insuring and the awareness of the Korean cases and Africa did not make a huge impact on many students. However, few students started breaking their own barriers and tried to be the ones who act globally.

Pulmonary alveolar hemorrhage from a pulmonary artery false aneurysm after Swan-Ganz catheterization in a thoracic aortic aneurysm patient -a case report-

Daisuke Sugiyama,Shigeo Ikeno,Tetsuya Tsuchihashi,Shigeru Yokota,Hiroaki Ina,Tetsuya Kono,Kunihiko Yamashita,Mikito Kawamata 대한마취통증의학회 2014 Korean Journal of Anesthesiology Vol.67 No.5

Pulmonary artery (PA) rupture caused by a PA Swan-Ganz catheter is a rare complication but remains fatal in almost50% of cases. False aneurysm of the PA is a rare presentation of PA rupture and should be considered as a possible diagnosisin a patient with a new lung mass after PA catheterization. We present a case of sudden-onset pulmonary alveolarhemorrhage during cardiovascular surgery due to a traumatic PA false aneurysm. The Swan-Ganz catheter might havebeen displaced by the thoracic aortic aneurysm with displacement of the catheter causing the false aneurysm and bleeding.

A heavy rainfall in July 2018 caused sediment disasters in West Japan. In this disaster, some debris flow were occured on slopes that were not recognized the potential of the occurence of sediment disasters. In this report, based on the results of the sediment disaster emergency survey conducted in several cities in West Japan, we will report the distribution and examples of slopes where these disasters occurred. In addition, regarding the occurrence of debris flow, the features related to topography and weather were examined. In Japan, the hazards of sediment disasters are recognized based on whether the topography of the slope has the same conditions as the topography of sediment disasters that occurred in the past. In this report, we focused on the debris flow occured on the slope that was not recognized as a valley where the debris flow occurs(the valley depth is wider than the valley width). As a result of this survey, we were able to understand the characteristics of the debris flow that occurred at a slope that was not recognized dangerous of sediment disaster. We believe that this report will help improve the warning and evacuation system for future sediment disasters in Japan.

Glycosylation is an important post-translational modification that confers various biological activities, structural stability, and inter-molecular interactions to proteins. Baculovirus expression vector system (BEVS) is widely used to produce recombinant glycoproteins, which may not be suitable for clinical use due to differences in the N-linked glycan structure between insects and mammals. It is necessary to develop an appropriate model protein-base platform for glycoanalysis to engineer the insect-type N-glycosylation pathway into human type efficiently. In this study,we employed human plasma protein alpha 1-acid glycoprotein (α1AGP). Itwas highly secreted from cultured silkworm cells and larvae when using the BEVS and glycosylated with insect type N-linked glycans. Interestingly, when separated on SDS-PAGE, the purified recombinant α1AGP secreted into silkworm haemolymph generated six distinct products from three alternative translates, suggesting that α1AGP has variations for the recognition or choice of glycosylation sites.

In recent years, sediment disasters have been frequent in Japan triggered by heavy rainfall at typhoons and line-shaped rain band. When conducting a disaster survey, it is necessary to determine at first where the disaster is occurring and where the damage is large. In the case of sediment disasters that distribute wide area, it is effective to use aerial photograph to understand the disaster situation. We researched the characteristics of three cases of sediment disasters that occurred in Japan in recent years based on the result of the interpretation of aerial photographs taken just after disasters, and the detailed examination of field survey. The target sediment disasters are Typhoon No10 on August 2016, heavy rainfall in northern Kyusyu in July 2017, and West Japan heavy rainfall 2018. We report the characteristics of each sediment disaster from these results. These sediment disasters occurred in various types because the conditions under which these sediment disasters occurred were different, such as region, topography, geology, and rainfall. Understanding the differences of sediment disasters by region is considered to be important in order to reduce the damage caused by sediment disasters, such as the construction of erosion control facilities and the maintenance of a warning and evacuation system.

Characteristics of Riverbed Configuration Affected by River-crossing Structures

Takeyoshi Chibana,Daisuke Harada,Kimiko Yamashita,Tatsuya Asai 대한토목학회 2012 KSCE Journal of Civil Engineering Vol.16 No.2

In the middle reaches of gravel-bed rivers, the formation of alternate or linguoid bars provides a diverse microhabitat for many kinds of creatures, much as with riffle pools and dry riverbed areas. The riverbed configuration, however, is completely altered by river-crossing structures, such as weirs or drop structures, installed in a river channel. In this study, both a large river and a small stream that have many river-crossing structures were targeted, and the characteristic feature of the topography in a river channel was investigated. Consequently, there was clarification that a similar pattern of topography was created in both rivers. The elevation gap between the bank and the riverbed was largest just downstream of a river-crossing structure but decreased in the flow direction and disappeared upstream of the next structure. Contrastingly, the width of the low-flow channel was narrowest just downstream of a river-crossing structure and gradually increased in the flow direction. The implication was that the longitudinal profile of the bank was determined by significant past floods and the low-flow channel was gradually created by small floods afterwards. Based on these results, we conclude that a change of river-crossing structure height is effective to manage the floodplain for habitat control, and the installation of large boulder is also effective to restore the low-flow channel.

( Kenji Tateda ),( Satoshi Nagoya ),( Daisuke Suzuki ),( Ima Kosukegawa ),( Toshihiko Yamashita ) 대한고관절학회 2021 Hip and Pelvis Vol.33 No.1

Purpose: The current study aimed to investigate the morphology of the true acetabulum in developmental dysplasia of the hip (DDH) with high dislocation. A secondary was to evaluate the acetabular cup placement in patients with high dislocation who were treated with total hip arthroplasty (THA). Materials and Methods: Using a retrospective design, 23 hips with DDH with high dislocation in patients who were treated with THA were included in this study. We measured the depth, width and thickness of the anterior and posterior walls of the original acetabulum using preoperative computed tomography images and investigated the cup size applied in these cases. Results: The mean depth and width of the acetabulum was 18.4 and 16.2 mm proximal end, 18.4 and 24.3 mm in the middle, and 15.8 and 27.6 mm at the distal part. Mean thickness of the anterior and posterior walls was 10.9 and 23.9 mm at the proximal end, 10.3 and 22.2 mm in the middle, and 10.9 and 22.7 mm at the distal part. A 42-mm cup was using in one hip, a 46-mm cup in three hips, a 48-mm cup in 13 hips, and a 50-mm cup in six hips. Conclusion: In patients with Crowe IV DDH, the morphology of the acetabulum comprises a triangle that broadens from proximal to distal points, with a relatively thick posterior wall. Reaming the acetabulum posteriorly and inferiorly may enable the placement of a relatively larger cup to achieve stable fixation.

Target-Composition Effect on Hydroxyapatite Thin Films Coated on Titanium by r.f. Sputtering

Hamagami, Jun-ichi,Kokubu, Daisuke,Umegaki, Takao,Yamashita, Kimihiro The Korean Ceramic Society 1998 The Korean journal of ceramics Vol.4 No.4

Using calcium-phosphate-powder targets with the Ca/P ratios of 1.0-1.67, hydroxyapatite ($Ca_{10}(PO_4)_6(OH)_2$, HAp) thin films with 4-7㎛ thickness were prepared on titanium metal plates by r.f. magnetron sputtering, followed an annealing at $200^{\circ}C$ for 24 hr under a high water vapor pressure using an autoclave. All the specimens were systematically characterized by XRD, FT-IR, SEM and EDS analyses. The post-annealed films were confirmed to be a nonstoichiometric oxyhydroxyapatite by XRD and FT-IR measurements.
