본 논문에서는 동북아해역의 언어지리학을 연구하기 위해서는 지역성을 나타내야 한다고 지적하고 있다. 그 지역의 지리학적 분석을 고려해 볼 때, "지역주의"는 아시아 언어의 형성과 언어적 행동에 영향을 미쳐야 한다. 따라서 "지역성"을 명확히 파악하기 위한 목적으로 가장 중요한 것은 그것을 어떻게 받아들이고 인식하느냐 하는 방법이다.그것들을 해결하기 위해서 먼저 저자와 교신저자는 일본의 도호쿠 지방의 방언으로 상황을 묘사하는 특징을 명확히 밝혀야 했다. 특히, 필자들은 그 지역의 아스펙트(시간적) 표현을 어떻게 표현하는지 요약해 보았다. 이러한 관점에서 볼 때, 조사 대상 지역의 동쪽과 서쪽 사이에 "지역성"의 차이가 분명하게 나타나 있음을 확인할 수 있다. 그것은 일본 방언의 형성 과정을 분석할 수 있다는 것을 뒷받침한다.더욱이 "지역성"은 일본어뿐만 아니라 한국어로도 확인해 볼 수 있다. 상황을 묘사할 때와 같은 특징이 한국어로도 나타난다. 이와 같은 상황은 언어는 다르지만 상황을 설명하는 데는 비슷한 특징이 있다는 것을 의미한다. 따라서 "지역성"은 동북아 지역의 언어지리학적 측면을 조사하는 데 중요한 의미가 있음을 보여준 결과라고 볼 수 있다. In this paper, to study of geolinguistics in the Northeast Asian sea region, it indicates that it propose the idea of "regionality" (it indicates the features of each region) is necessary. In considering to analyze the geolinguistics in that area, “regionality” should be affecting its formation and verbal behavior of the languages in Asian. Thus, of aiming to clarify “regionality”, the matters is how to capture and recognize it.In order to solve them, firstly, we clarify the features of depiction of the situation in the dialect of Tohoku region of Japan. Especially, we summarize how to represent temporal expressions in the region. In this point of view, the difference of the “regionality” between east side and west side of the area become clarify. It supports that the formation process of Japanese dialects are analyzed.In addition, the “regionality” can be seen not only in Japanese but also in Korean. The same features of depiction of the situation also appear in Korean. They are different language, but they have similar features for describing the situations. Therefore, “regionality” indicates that there is an important meaning in investigating the geolinguistics of the Northeast Asian sea region.

This study examines the influence of parental social support and resiliency of efficacy on stress, depression and stress management behavior. A total of 799 participants (male=386, female=413), consisting of 184 elementary school, 354 middle school, 274 university students completed a questionnaire that included Rhode Island Stress Scale (Horiuchi, Tsuda, Tanaka, Yajima & Tsuda, in press), Stress Management Behavior Scale (Evers, Prochaska, Johnson, Mauriello, Padula & Prochaska, 2006), Becks' Depression Inventory (BDI-Ⅱ, Beck, Steer & Brown, 1996; CES-D, Radloff, 1977), Resiliency of Efficacy (Bandura, 1995), and Parental Social Support (Kim & Park, 1999). The results of path analysis are as follows. First, resiliency of Efficacy had a direct and negative effect on stress and depression and direct positive effect on stress management. Second, stress management behavior did not have any influence on stress. Third, parental social support had a direct and positive effect on resiliency of efficacy. This pattern of results were found for elementary school, middle school and university students. When depression was measured by CES-D Scale (Center for Epidemiological Study of Depression) parental social support and resiliency of efficacy had a different parental of influence on stress, depression and stress management behavior, pointing out the importance of conducting comparative analysis of various measures of depression.

We studied the effects of partial spraying, targeting tea [Camellia sinensis (L.) O. Kuntze] plants' plucking surfaces, on the annual number of major pests and damage to new shoots. The prevention of feeding damage to shoots caused by Empoasca onukii Matsuda (Hemiptera: Cicadellidae) was more stable when spraying at high volumes. However, the annual number of E. onukii with conventional spraying (200 L/1000 m 2 ) was similar to the control (No pesticide). On the other hand, the prevention effect on shoots and the annual number of Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) in partial spraying (40 L/1000 m 2 ) was similar to conventional spraying. Moreover, although high volumes of spraying (1000 L/1000 m 2 ) are usually needed to control Pseudaulacaspis pentagona (Targioni-Tozetti) (Hemiptera: Diaspididae), the male adult population of P. pentagona in the control and partially sprayed field tended to be lower than that in the conventional spraying. When using pesticides harmful to P. pentagona's natural enemies, partial spraying seems beneficial. Enough pesticide spraying to widely cover the leaf layer was thought necessary to protect the tea plants' new shoots. However, the spraying method targeting only the tea plants' plucking surfaces protects the new shoots with similar efficacy. Besides, partial spraying protects pests' natural enemies, allowing additional pest population control.

Purpose: Postoperative pancreatic fistula is a serious and fatal complication of gastrectomy for gastric cancer. Blunt trauma to the parenchyma of the pancreas can result from an assistant's forceps compressing and retracting the pancreas, which in turn may result in pancreatic juice leakage. However, no published studies have focused on blunt trauma to the pancreas during laparoscopic surgery. Our aim was to investigate the relationship between compression of the pancreas and pancreatic juice leakage in a swine model. Materials and Methods: Three female pigs were used in this study. The pancreas was gently compressed dorsally for 15 minutes laparoscopically with gauze grasped with forceps. Pancreatic juice leakage was visualized by fluorescence imaging after topical administration of chymotrypsin-activatable fluorophore in real time. Amylase concentrations in ascites collected at specified times was measured. In addition, pancreatic tissue was fixed with formalin, and the histology of the compressed sites was evaluated. Results: Fluorescence imaging enabled visualization of pancreatic juice leaking into ascites around the pancreas. Median concentrations of pancreatic amylase in ascites increased from 46 U/L preoperatively to 12,509 U/L 4 hours after compression. Histological examination of tissues obtained 4 hours after compression revealed necrotic pancreatic acinar cells extending from the surface to deep within the pancreas and infiltration of inflammatory cells. Conclusions: Pancreatic compression by the assistant's forceps can contribute to pancreatic juice leakage. These findings will help to improve the procedure for lymph node dissection around the pancreas during laparoscopic gastrectomy.

Pu-Erh Tea Hot-Water Extract Activates Akt and Induces Insulin-Independent Glucose Transport in Rat Skeletal Muscle

Xiao Ma,Satoshi Tsuda,Xin Yang,Ning Gu,Hiroko Tanabe,Rieko Oshima,Tetsuya Matsushita,Tatsuro Egawa,Ai-Jun Dong,Bei-Wei Zhu,Tatsuya Hayashi 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.3

Skeletal muscle is a major organ that is important for whole-body glucose metabolism. We found that when isolated rat epitrochlearis muscle was incubated with a Pu-erh tea hot-water extract (PTE) for 30 min, the rate of 3-O-methyl-D-glucose (3MG) transport increased in the absence of insulin. This activation was associated with an increase in Ser473 phosphorylation of Akt, a signaling intermediary leading to insulin-dependent glucose transport, but not Tyr458 phosphorylation of phosphoinositide 3-kinase p85, an upstream molecule of Akt. PTE-stimulated 3MG transport was also not accompanied by Thr172 phosphorylation of the catalytic α-subunit of 5′-AMP-activated protein kinase (AMPK). Gallic acid, a water-soluble ingredient in Pu-erh tea, stimulated Akt phosphorylation, but not AMPK phosphorylation. These results suggest that Pu-erh tea potentially promotes skeletal muscle glucose transport at least in part by activating Akt.

동북아해역 서양 외래어의 유입에 관한 연구

양민호(Yang Minho),津田智史(Tsuda Satoshi) 부경대학교 인문사회과학연구소 2018 인문사회과학연구 Vol.19 No.3

본 논문은 동북아해역의 서양 외래어에 대한 연구로 일본의 나가사키를 통해 유입된 네덜란드 기원의 외래어에 관하여 살펴보도록 하겠다. 주된 내용은 에도 시대 때 네덜란드어를 중심으로 일본에 유입되어 정착된 용어 중 바다관련 어휘와 현재까지 자기 영역을 견고히 지키고 있는 네덜란드어의 흔적을 더듬어 가며 살펴보고자 하였다. 일본의 서양 문화와의 접촉은 무로마치 시대 이후 외국과의 교류와 접촉을 시작하여 현재까지 계속되고 있는데, 당시 많은 외래어를 손쉽게 흡수하고 수용하여 현재까지 꾸준히 사용하게 되었다. 특히 그 중에서 가라스(Glas)와 콥뿌(Kop)처럼 네덜란드어 기원의 말은 영어 기원의 그라스(Glass)와 캅뿌(Cup) 어휘와 경쟁을 하였지만 선사용(先使用) 어휘의 장점 즉 선점 효과를 통해 그 자리를 영어에 내주지 않고 독자적으로 자신의 의미 영역을 담당하게 되었다. 에도 시대에 들어온 네덜란드어는 과학, 기술, 문화 등 다양한 분야에서 빛을 발하고 있지만 특히 바다 관련 용어에서도 두드러지게 나타나고 있다. 예를 들어 데키(Dek), 도크(Dok), 마스토(Mast), 후라이키(Vlag), 마도로스(Matroos) 등과 같이 네덜란드어가 아직까지 그대로 남아 있는 형태도 존재하지만 해역을 중심으로 퍼져나가면서 바닷가 말 형태로 방언 속에 숨겨져 존재하는 경우도 있다. 이와 같은 연구는 단편적 흐름만으로는 파악할 수도, 해결할 수도 없다. 향후 동북아해역과 인문네트워크라는 큰 연구 주제 속에 합리적이고 지속적인 노력으로만 해결이 가능하리라 생각된다. 다만 본 논문에서는 동북아해역의 외래문화 유입에 대하여 일부지역(일본), 일부언어(네덜란드)만을 대상으로 개략적으로 살펴보았다. 앞으로는 동북아해역을 보다 면밀하고 세분화하여 후속 연구를 진행하고자 한다. In this paper, we will study Western languages in Northeast Asia sea region and find out about them from the Netherlands origin that came through Nagasaki, Japan. The main analysis is the word sea related among the terms introduced in Japan in the Edo period, centered on Netherlands. And I tried to trace the traces of the Netherlands language that remains so far. Contact with Western culture has continued since the age of Muromachi and since then, since then, foreign exchange and contact with foreign countries. Thus, many foreign words were easily absorbed and accepted at that time. Among them, Netherlands origin words, such as Glas and Kop, have not been given meaning to the English language. Netherlands, which entered the Edo era, is shining in various fields such as science, technology, and culture, but it is especially evident in terms of sea. Some forms of Netherlands language still remain, for example, Dek, Dok, Mast, Vlag, and Matros. However, in some cases, it is hidden in dialect in the form of seaside words(Hama Gotoba) as it spreads out around sea areas. Such studies cannot be determined by simple analysis. we think that in the future, we will be able to understand accurately and resolve the issue through reasonable and continuous efforts amid the large research topics of Northeast Asia Sea and the humanities network. In this paper, we reviewed only some regions (Japan) and some languages (Netherlands) for the inflow of foreign cultures into Northeast Asia sea region, but we will conduct further research by making the area more detailed and detailed.

Saito, Kimiaki,Mikami, Satoshi,Andoh, Masaki,Matsuda, Norihiro,Kinase, Sakae,Tsuda, Shuichi,Sato, Tetsuro,Seki, Akiyuki,Sanada, Yukihisa,Wainwright-Murakami, Haruko,Yoshimura, Kazuya,Takemiya, Hiroshi The Korean Association for Radiation Protection 2019 방사선방어학회지 Vol.44 No.4

Massive environmental monitoring has been conducted continuously since the Fukushima Daiichi Nuclear Power accident in March of 2011 by different monitoring methods that have different features together with migration studies of radiocesium in diverse environments. These results have clarified the characteristics of radiological environments and their temporal change around the Fukushima site. At three months after the accident, multiple radionuclides including radiostrontium and plutonium were detected in many locations; and it was confirmed that radiocesium was most important from the viewpoint of long-term exposure. Radiation levels around the Fukushima site have decreased greatly over time. The decreasing trend was found to change variously according to local conditions. The air dose rates in environments related to human living have decreased faster than expected from radioactive decay by a factor of 2-3 on average; those in pure forest have decreased more closely to physical decay. The main causes of air dose rate reduction were judged to be radioactive decay, movement of radiocesium in vertical and horizontal directions, and decontamination. Land-use categories and human activities have significantly affected the reduction tendency. Difference in the air dose rate reduction trends can be explained qualitatively according to the knowledge obtained in radiocesium migration studies; whereas, the quantitative explanation for individual sites is an important future challenge. The ecological half-lives of air dose rates have been evaluated by several researchers, and a short-term half-life within 1 year was commonly observed in the studies. An empirical model for predicting air dose rate distribution was developed based on statistical analysis of an extensive car-borne survey dataset, which enabled the prediction with confidence intervals. Different types of contamination maps were integrated to better quantify the spatial data. The obtained data were used for extended studies such as for identifying the main reactor that caused the contamination of arbitrary regions and developing standard procedures for environmental measurement and sampling. Annual external exposure doses for residents who intended to return to their homes were estimated as within a few millisieverts. Different forms of environmental data and knowledge have been provided for wide spectrum of people. Diverse aspects of lessons learned from the Fukushima accident, including practical ones, must be passed on to future generations.

Numerical Study on Loss Mechanism in Rear Rotor of Contra-Rotating Axial Flow Pump

De Zhang,Yusuke Katayama,Satoshi Watanabe,Shin-Ichi Tsuda,Akinori Furukawa 한국유체기계학회 2020 International journal of fluid machinery and syste Vol.13 No.1

It is known that higher efficiency can be achieved with reduced specific speed design of rear rotor in contra-rotating axial flow pump. To investigate the mechanism of increased efficiency with the reduced specific speed of rear rotor, three models with different specific-speed rear rotors are designed with the conventional method, and the flow fields are simulated by unsteady RANS simulation. To analyze the loss generation mechanism, two loss evaluation methods based on the entropy production rate and the material-derivative of rothalpy are employed. It is found that, although the both methods qualitatively estimate the total loss through the rear rotor, the derivative of rothalpy can give much better quantitative prediction of the losses. Two distinct flow features are observed in the rear rotor, the corner separation at the hub corner of blades and the tip leakage vortex, both of which are responsible for the loss generation. With the evaluation of local loss generation based on the material derivative of rothalpy, the loss contribution of corner separation is found to be very small compared with that due to the tip leakage vortex. The tip leakage vortex structure in high specific speed rear rotor shows the strong interaction with the leading edge of adjacent blade, which seems to strengthen the blockage effect in the tip region. This is relieved in the lower specific speed rear rotor, resulting in the achievement of higher efficiency with it.

Background/Aims: Endoscopic submucosal dissection (ESD) for diverticulum-associated colorectal lesions is generally contraindicatedbecause of the high risk of perforation. Several studies on patients with such lesions treated with ESD have been reported recently. However, the feasibility and safety of ESD for lesions in proximity to a colonic diverticulum (D-ESD) have not been fully clarified. Theaim of this study was to evaluate the feasibility and safety of D-ESD. Methods: D-ESD was defined as ESD for lesions within approximately 3 mm of a diverticulum. Twenty-six consecutive patients whounderwent D-ESD were included. Two strategic approaches were used depending on whether submucosal dissection of the diverticulum-related part was required (strategy B) or not (strategy A). Treatment outcomes and adverse events associated with each strategywere analyzed. Results: The en bloc resection rate was 96.2%. The R0 and curative resection rates were 76.4% and 70.6% in strategy A and 88.9% and77.8% in strategy B, respectively. Two cases of intraoperative perforation and one case of delayed perforation occurred. The delayed perforationcase required emergency surgery, but the other cases were managed conservatively. Conclusions: D-ESD may be a feasible treatment option. However, it should be performed in a high-volume center by expert handsbecause it requires highly skilled endoscopic techniques.
