Recently, needs for reduction of raw material usage and use of low-quality raw materials have been growing in each steelworks. When the time has been ripe for prevention of global warming, the introduction of energy-saving equipment is also required investments in the iron- and steelmaking industry. In response to these needs, a coal moisture control system（hereafter referred to as "CMC"） has been introduced to produce coking coal for environmental preservation and energy conservation purposes. CMC is a preliminary coal treatment process in which charge coal for a coke oven is dried and is expected to bring about the advantages of "reduced carbonization heat value of coke ovens," "improved coke quality," and "increased coke production." Since the introduction of the steam tube dryer（STD） type CMC of the 1st generation in 1983, Nippon Steel Corporation（NSC） has pursued the improvement of equipment and processes, and succeeded in developing the fluidized bed（FB） type CMC of the 3rd generation in 1996. Currently, NSC has been constructing the FB type CMC in Maanshan Iron ＆ Steel Co., Ltd. as the New Energy and Industrial Technology Development Organization（NEDO） project between China and Japan. The FB type CMC of Nippon Steel Engineering Co., Ltd.（NSEC） makes use of coke oven exhaust gas for fluidization gas and is a process with the higher effect of energy conservation than that of STD type CMC that uses steam as a drying heat source, etc. Furthermore, in China an FB type CMC that dries coking coal before pulverization has been running, but NSEC FB type CNC is a process that dries coking coal after pulverization. NSC conducted experiment on the drying efficiency of these two types of fluidized bed（FB） dryers and has conformed that the smaller the grain size would be, the higher the drying efficiency would be, which enables a fluidized bed to be formed without partial excess drying and overheat.

Malnutrition Assessed Using the Geriatric Nutritional Risk Index Is Associated with Preoperative Incidence of Deep Vein Thrombosis in Japanese Patients Undergoing Total Knee Arthroplasty

引用

Open Journal of Orthopedics 2024年第8期14卷 355-365页

作者： Taizo kaneko Kentaro Hayakawa Tsuyoshi Miyazaki Department of Orthopaedic Surgery Tokyo Metropolitan Institute for Geriatrics and Gerontology Tokyo Japan

Purpose: Few studies have evaluated the association between malnutrition and the risk of preoperative deep vein thrombosis (DVT) in patients undergoing primary total joint arthroplasty. This study aimed to investigate the prevalence of preoperative DVT in Japanese patients undergoing total knee arthroplasty (TKA) and the importance of malnutrition in the risk of preoperative DVT. Methods: We retrospectively analyzed 394 patients admitted for primary TKA at our institution between January 2019 and December 2023. All patients scheduled for TKA at our institution had serum D-dimer levels measured preoperatively. Lower-limb ultrasonography was examined to confirm the presence of DVT in patients with D-dimer levels ≥ 1.0 µg/mL or who were considered to be at high risk of DVT by the treating physician. Based on the results of lower-limb ultrasonography, all patients were divided into the non-DVT and DVT groups. The incidence of and risk factors for preoperative DVT were investigated, as well as the correlation of DVT with the patient’s nutritional parameters. We used two representative tools for nutritional assessment: the Geriatric Nutritional Risk Index (GNRI) and Controlling Nutritional Status Score. Results: The mean age was 77.8 ± 6.9 years. Preoperative DVT was diagnosed in 57 of the 394 (14.5%) patients. Multivariate logistic regression analysis showed that advanced age and malnutrition status, assessed using the GNRI, were independent risk factors for preoperative DVT. Conclusion: A high incidence of preoperative DVT was observed in patients who underwent TKA. Malnutrition status, as assessed using the GNRI, increased the risk of preoperative DVT. Our findings suggest that clinicians should consider these factors when tailoring preventive strategies to mitigate DVT risk in patients undergoing TKA.

Malnutrition and Its Association with the Mortality of Patients with Femoral Intertrochanteric Fractures: A Retrospective Analysis of Japanese Patients

引用

Open Journal of Orthopedics 2024年第1期14卷 22-31页

作者： Taizo kaneko Kyoko Matsudaira Kentaro Hayakawa Fumiaki Tokimura Tsuyoshi Miyazaki Department of Orthopaedic Surgery Tokyo Metropolitan Institute for Geriatrics and Gerontology Tokyo Japan

Background: The incidence of femoral intertrochanteric fractures in older adults is higher than that of femoral neck fractures;however, both conditions are often analyzed together as proximal femoral fractures. Considering the difference in treatment, postoperative complication, and mortality risk, these two fractures should be analyzed separately. This study aimed to analyze 1-year mortality and its risk factors in patients with surgically treated femoral intertrochanteric fractures. Methods: Consecutive patients with intertrochanteric fractures who underwent surgical interventions at our institution between January 2017 and December 2021 were retrospectively reviewed. A total of 238 patients were eligible for inclusion in this study. Patients’ demographic and clinical information were retrospectively collected. Patients were divided into the 1-year mortality (n = 16) and survival (n = 222) groups. The incidence of 1-year mortality and its independent risk factors were investigated using univariate and multivariate logistic regression analyses. Results: The mean age of patients was 85.6 ± 8.5 years. The 1-year mortality rate was 6.7% (16/238). Preoperative albumin level, the Geriatric Nutritional Risk Index (GNRI), and malnutrition status (GNRI p = 0.02, p = 0.02, and p = 0.0011, respectively). Multivariate analysis showed that malnutrition status (GNRI p = 0.035) was an independent risk factor for 1-year mortality. Conclusion: Malnutrition status assessed using GNRI (GNRI < 92) was an independent risk factor for 1-year mortality. Our findings suggest that GNRI may be an effective screening tool for predicting postoperative 1-year mortality of patients with surgically treated femoral intertrochanteric fractures.

A Case Report of Kissing Molars Class II

引用

Open Journal of Stomatology 2024年第5期14卷 249-254页

作者： Toshiyuki Inou Keiichi Uchida Keiko kaneko Anna Fuji Nina Wakimoto Tatsuo Takaya Hiroyuki Kitamura Hiroshi Mori Yuji Kurihara Department of Oral Diagnostics and Comprehensive Dentistry Matsumoto Dental University Hospital Shiojiri Japan Department of Oral and Maxillofacial Surgery School of Dentistry Matsumoto Dental University Shiojiri Japan

Kissing molars (KMs) is a condition of occlusal molar surfaces in a single follicular space with roots extending in opposite directions. Here, we have reported a case of KMs in a 58-year-old woman. The patient complained of pain in the right mandibular molar region and was diagnosed with KMs consisting of the right mandibular second and third molars. Because of the patient’s pain having subsided at the time of the visit and her unwillingness to undergo tooth extraction, the patient was followed up. KMs is classified into three classes (I-III) and is either true-KMs or pseudo-KMs and presents with or without cystic variants of dental follicles. The presents as true-KMs class II without a cystic variant. With reference to the literature and based on our analysis, the mean age of patients affected by this specific case of KMs is 31.7 years and unilateral KMs is relatively more common (85.7%). Histopathological findings of dentigerous cysts are more often indicated (42.9%). The treatment policy for KMs should therefore be based on the classification of KMs. Importantly, the focus should be on preserving the first and second molars as much as possible. The treatment approach, such as the employment of surgical removal or orthodontics, should be determined by considering the associated factors such as the crowns, tissues, and age of the patient.

沿海声层析(Coastal Acoustic Tomography,简称CAT)是利用高频声信号实现近海大范围流场观测的有效手段,但其直接观测范围仍然有限。海洋数值模式提供了一种存在仿真误差的大范围海洋背景场,将CAT观测结果与海洋背景结果同化,可以提高流场结果的分辨率和准确度。本文提出一种利用流函数拟合海洋模式流场结果并使用集合卡尔曼滤波算法同化CAT数据的方法,获得更大范围的海洋水平二维流场结果。同化研究以非结构化网格有限体积海洋数值模式(Finite-Volume Community Ocean Model,简称FVCOM)作为背景场,以2016年6月1日至3日在印度尼西亚巴厘海峡(Bali Strait)进行的4站CAT实验作为观测数据。经过背景场流函数拟合和CAT数据同化,获得巴厘海峡二维流场。同化结果分别与同期观测结果和潮位数据对比,发现流函数拟合同化后的流场能更准确地描述巴厘海峡涨落潮和流量情况,通过引入CAT数据与流场的函数关系,可以有效地降低海洋模式的误差和原观测数据的稀疏性。

Numerical Investigation of Influence of Tip Leakage Flow on Secondary Flow in Transonic Centrifugal Compressor at Design Condition

引用

Journal of Thermal Science 2015年第2期24卷 117-122页

作者： Masanao kaneko Hoshio Tsujita Graduate School of Engineering Hosei University3-7-2Kajino-choKoganei-shiTokyo184-8584Japan Department of Mechanical Engineering Faculty of Science and EngineeringHosei University

In a centrifugal compressor, the leakage flow through the tip clearance generates the tip leakage vortex by the in- teraction with the main flow, and consequently makes the flow in the impeller passage more complex by the inte- raction with the passage vortex. In addition, the tip leakage vortex interacts with the shock wave on the suction surface near the blade tip in the transonic centrifugal compressor impeller. Therefore, the detailed examination for the influence of the tip leakage vortex becomes seriously important to improve the aerodynamic performance cs- pccia｜ly for the transonic centrifugal compressor. In this study, the flows in the transonic centrifugal compressor with and without the tip clearance at the design condition were analyzed numerically by using the commercial CFD code. The computed results revealed that the tip leakage vortex induced by the high loading at the blade tip around the leading edge affected the loss generation by the reduction or the suppression of the shock wave on the suction surface of the blade.
