Distribution of Overwintering Pondloaches (Misgurnus Anguillicaudatus) in Rice fields in Japan
( Hiroshi Jinguji ),( Katsuya Miyai ),신문호 ( Moono Shin ) 한국농공학회 2020 한국농공학회 학술대회초록집 Vol.2020 No.-
The Pond loach, Misgurnus anguillicaudatus (Cantor, 1842), is widespread in rivers, ponds, swamps and rice fields in Korea and Japan. Although M. anguillicaudatus is a common fresh water fish, it is classified as near threatened in the Red Data list published by the Ministry of Environment, Japan. Korea and Japan have a culture of consuming loaches and the decrease in loach populations may cause the loss of traditional food culture. This study examined the optimal environmental conditions for overwintering loaches in rice fields. The study site was located in Osaki-machi in Miyagi Prefecture, Japan. We randomly collected paddy surface soil (30 cm depth) from 20 rice fields, and M. anguillicaudatus specimen s f rom a p it i n a dry d rain age canal. Misgurnus anguillicaudatus specimens were kept individually in beakers, and body mass and standard length were measured. A total of 19 M. anguillicaudatus specimens were collected from seven rice fields and 31 specimens were collected from the drainage canal. The M. anguillicaudatus that were overwintering in the soil were concentrated in shallow water near the water inlets or outlets of the rice fields. The mean standard length of all M. anguillicaudatus collected in the rice fields and in the pit in the drainage canal was 56.5±11.7mm and 49.9±10.5mm, respectively. There was no significant difference in the body length of the two groups. Our findings suggest that M. anguillicaudatus overwinters in wet and poorly drained rice fields.

Parent Artery Complex Coil Protection for Side-Branched Wide-Neck Aneurysms
Sato Keisuke,Aoki Hiroshi,Jinguji Shinya,Seto Hiroki,Kobayashi Tsutomu 대한신경중재치료의학회 2022 Neurointervention Vol.17 No.2
This study aimed to validate the usefulness of parent artery complex coil protection for the treatment of wide-neck, side-branched, and ruptured aneurysms. A microcatheter was first introduced into the aneurysmal sac, and another microcatheter was introduced into the parent artery or near the orifice of the branch artery. A framing coil was deployed partially from the first microcatheter, and a protection coil was deployed from the second microcatheter to prevent protrusion of the first framing coil to the parent artery and side branches. After the first framing coil insertion, the protection coil was withdrawn to confirm the stability of the framing coil and blood flow. The procedures with this technique were successful for 3 patients. Parent artery complex coil protection can be an effective and safe coil embolization technique for the preservation of parent and side branch arteries and an alternative method for emergent ruptured cases.

The impact of the nuclear power plant accident in Japan on agricultural and rural engineering
신문호 ( Moono Shin ),( Hiroshi Jinguji ) 한국농공학회 2020 한국농공학회 학술대회초록집 Vol.2020 No.-
The Great East Japan Earthquake that occurred in March 2011, along with the accident at the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant, caused about $2.2 billion in damage to approximately 4,300 agricultural land and agricultural facilities, including farmland, levees, drainage pumping stations and waterways in Fukushima Prefecture, Japan. In addition, recovery and decontamination work have been progressing since the accident at the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant, and farming has been resumed with the lifting of the evacuation order except for the difficult-to-return zone. In this study, we report on the measures and results taken after the earthquake, such as decontamination of farmland, measures to inhibit absorption through potassium fertilization, and elucidation of the dynamics of radioactive cesium in agricultural land. It was revealed that the areas to the evacuation instructions were lifted, the impact on brown rice from radioactive cesium in the irrigation water was limited, if soil improvement was conducted to increase the content of exchangeable potassium to 200 (mgㆍK)/kg soil before the conventional application. It is also necessary to deepen farmers' and consumers' understanding of the safety of agricultural products from Fukushima Prefecture, Japan, and an important issue is how to provide public support for farmers to put this into practice themselves.
