This account reports an overview of our findings in homogeneous Pd-catalyzed reactions. Herein we describe the new design in reactions of Group 14 element compounds and in homogeneous nanosize Pd catalysts. In the early stages of our study, we developed Pd-catalyzed transformations of allylic esters with disilanes, silylcyanides and acylsilanes to the corresponding silylation, cyanation and acylation products, respectively. We also developed a Pd-catalyzed three component coupling reaction of Group 14 element compounds involving 1,3-diene and acid chlorides to form β,γ-unsaturated ketone as a single product. Recently, we focus our attention on modifying the catalytic environment by nanosize Pd in order to improve the performance of Pd catalysts. These nanosystems realize efficient catalytic environment with remarkable enhancement in catalytic activity and unprecedented selectivity.

TSR (Trans-Siberian Railway) route is losing price competitiveness versus Deep Sea route in the transportation from East Asia to Europe, including Moscow. To further attracting the containers to the TSR route, it will be necessary (1) to keep competitive through rate, linked to fluctuating Deep Sea rate; (2) to strengthen speed advantage; (3) to enforce seamless transportation system, including simplified customs clearance procedures. In transportation to Central Asia from East Asia (Korea and Japan), TSR is competitive versus TCR (Trans-China Railway), depending on destinations. Korea has been the leader in revitalizing the TSR route since 2000. Key contributors were affluent export containers to Russia and Central Asia, port of Busan, efficient maritime transport network to Far East Russia, and Korean forwarders' persistent efforts for activating the market. Korea and Japan have a possibility of cooperation in using the TSR route efficiently, such as organizing a joint block train to a same destination.
Mechanical Thrombectomy for Large Vessel Occlusion via the Transbrachial Approach: Case Series

Mechanical thrombectomy has become a standard treatment for acute ischemic stroke with large vessel occlusion. In aged patients, it is difficult to guide the catheter via the transfemoral approach due to vessel tortuosity and aortic elongation. We report our preliminary clinical experience using the transbrachial approach. Among the 119 patients who underwent thrombectomy from April 2018 to December 2019, a total of 5 patients were treated via the transbrachial approach. Clinical outcomes were retrospectively analyzed. Successful reperfusion was achieved in 4 out of 5 cases. There was 1 death due to symptomatic intracranial hemorrhage. One patient had a good outcome at discharge. There were no access-site complications associated with any of these cases. Transbrachial access for mechanical thrombectomy is feasible and can provide an alternative to the transfemoral approach.
Commodity Characteristics Preferred by Young People in Japan

This paper turns its attention to the commodities that enjoy a large sale among the university students in Japan. The aim of the study is to clarify by what criteria the university students purchase them. In order to investigate by what criteria they select goods and what constitutes the factors of selection, the method of factor analysis was applied. The method produced three factors as the criteria for selection: The 1. factor as "daily-non-daily", the 2. factor as "popular-regular" and 3. factor as "searching-dependent". This leads to the conclustion that the commodities have a good sale because of their characteristics of being suitable to daily life, being popular and being objects of searching activities among the young people in Japan.

Cerebral embolic stroke caused by a thrombus in the pulmonary vein stump after left pulmonary lobectomy is a serious complication. We retrospectively analyzed four patients who underwent mechanical thrombectomy for large-vessel occlusion after left pulmonary lobectomy between January 2014 and March 2022. Two cases occurred after left upper lobectomy and the others occurred after left lower lobectomy. All patients presented with cerebral embolic stroke from the day after surgery to the 9th postoperative day, and successful reperfusion was achieved in all cases. Two patients had good outcomes at 90 days. Thrombus in the pulmonary vein stump is the probable cause of cerebral embolism, and mechanical thrombectomy is effective. Further studies are required to establish preventive measures and perioperative management strategies.

Non-absorbable substances in foods, for instance dietary fiber had been previously known as a non-nutritive part of foods. Recently, such a category has been gradually changed to as one of nutrients. As a main reason, dietary fibers includes many poly- or oligo-saccharides, which are resistant to alimentary hydrolyzing enzyme. However, parts of them are fermented by intestinal microorganism to produce short chain fatty acids and so on. They are absorbed and utilized by human being. Now, it may be naturally accepted that dietary fiber is a kind of nutrients. letary fiber exerts many useful functions on body. They are classified into three large functions, physicochemical function, physiological function and biological function. The last function of dietary fiber will be presented in the symphosium. Ietary fiber has several kinds of nutritional properties. One is energy source. Short chain fatty adds (SCFA) are wddized and produced energy in body. Dietary fiber has not high energy, but not zero kilocalories. Another one is to be a constitutional component of higher animals' tissue. Last but most important one is physiological functions of dietary fiber.

This paper presents a mechanical sensorless vector-controlled system with parameter identification by the aid of image processor. Based on the flux observer and the model reference adaptive system method, the proposed sensorless system includes rotor speed estimation and stator resistance identification using flux errors. Since the mathematical model of this system is constructed in a synchronously rotating reference frame, a linear model is easily derived for analyzing the system stability, including motor operating state and parameter variations. Because it is difficult to identify rotor resistance simultaneously while estimating rotor speed, a low-accuracy image processor is used to measure the mechanical axis position for calculating the rotor speed at a steady-state operation. The rotor resistance is identified by the error between the estimated speed using the estimated flux and the calculated speed using the image processor. Finally, the validity of this proposed system has been proven through experimentation.
