The Use of Monolithic Refractories and Microwave Drying for RH Steelmaking Vessels
Kayama, Tsuneo,Hanagiri, Seiji,Sukenari, Shiro The Korean Ceramic Society 2000 The Korean journal of ceramics Vol.6 No.2
Monolithic refractory technology has been developed for RH vessels, with the purpose of reducing the total refractory cost. The technology includes the use of an improved monolithic refractory and microwave drying. The improved monolithic refractory was an alumina-spinel composition, of the type used in steel ladles, to which fine alumina was added to increase the density and corrosion resistance. The microwave drying method, previously developed and used to dry the monolithic lining in steel ladles, was modified for use in drying the dense, 500mm thick lining in RH vessels. This work has resulted in significant cost savings.

Malignant Melanoma of the Nipple: A Case Report
Yoshika Nagata,Manabu Yoshioka,Hidetaka Uramoto,Yosuke Tsurudome,Sohsuke Yamada,Takeshi Hanagiri,Fumihiro Tanaka 한국유방암학회 2018 Journal of breast cancer Vol.21 No.1
Malignant melanoma rarely originates from the female nipple. Tumors that develop on the skin of the breast are often subject to a delayed diagnosis. Cytologic examination provides excellent diagnostic capabilities and is a safe procedure with a lower risk of local implantation, compared to needle or incisional biopsy. We herein report a patient who underwent surgical resection of a primary malignant melanoma of the nipple. An elastic soft nodule was observed on the left nipple, and no abnormal lesions were identified in the breast. Eventually, a malignant melanoma was diagnosed from the clinical and cytological evaluation findings. This bulky tumor was classified as a stage IIIC nodular melanoma, with a thickness of 12 mm. The patient received adjuvant chemotherapy and exhibits no evidence of recurrence 7 years after surgery.

Objectives: Chronic obstructive pulmonary disease (COPD) is a risk factor for osteoporosis. Nevertheless, much remains unclear regarding the bone metabolism dynamics associated with COPD. The present study focuses on the associations between the COPD severity and serum bone metabolism biomarkers. Methods: We enrolled 40 patients who visited the orthopedics departments at our institutions and underwent dual-energy X-ray absorptiometry between September 2015 and December 2017. Only male osteoporosis patients over 45 years of age were included, and 5 patients were excluded due to disease or use of internal medicines affecting bone metabolism. All subjects underwent lung function testing, spine radiography, and blood tests. We measured percent forced expiratory volume in 1 second (%FEV1), which reflects COPD severity, and we examined the relationships between %FEV1 and serum levels of bone metabolism biomarkers. Results: All subjects were diagnosed with osteoporosis based on T-scores. %FEV1 correlated with body weight, body mass index (BMI), and Z-score/T-scores. %FEV1 moderately correlated with serum levels of alkaline phosphatase (ALP), procollagen type 1 N-terminal propeptide (P1NP), and tartrate-resistant acid phosphatase 5b in the partial correlation analysis adjusted for BMI or T-score in the lumbar vertebrae. We performed a hierarchical multiple regression analysis to identify that serum ALP and P1NP were the independent explanatory variables to %FEV1 independent of other factors. Conclusions: The data suggest that the COPD severity in middle-aged and older men with osteoporosis associates with decreased bone formation. COPD patients may exhibit bone metabolism dynamics characterized by low bone turnover with osteogenesis dysfunction as COPD becomes severe.
