Effect of Impact Velocity on Interface Characteristics of HT‑9 Steel Joints Fabricated by Magnetic Pulse Welding

Jun‑Woo Song,Jin‑Ju Park,Gyoung‑Ja Lee,Min‑Ku Lee,Kyu‑Hyun Park,Soon‑Jik Hong,Jung Gu Lee 대한금속·재료학회 2020 METALS AND MATERIALS International Vol.26 No.3

The weldability window in magnetic pulse welding (MPW) is proposed for the end-closure joining of HT-9 steel tubularworkpieces. Based on both theoretical and experimental investigations, the impact velocity of the flyer tube at the momentof collision had a dominant effect on the bonding characteristics of the resultant joints and the optimal impact velocity wasestimated to be in the range of 265–290 m/s in this alloy system. Under the optimal process conditions, no leak was detectedduring helium leak testing. Moreover, the integrity of the joint interface was preserved until the tube section ruptured duringinternal pressure burst testing. For HT-9 steel, the ductile δ-ferrite phase produced by the localized interfacial melting duringMPW acted as an effective obstacle to crack propagation, thereby enhancing the fracture resistance of the joint interface. Allof the results demonstrated the high integrity and durability of the HT-9 steel tube assembly fabricated by the MPW process.

EDSA를 이용한 비상발전기 운영에 관한 연구

While everyone who uses electric power desires perfect frequency, voltage, stability, and reliability at all times, this cannot be realized in practice. The supplying utility cannot be expected to provide a perfect power supply because many of the causes of power supply disturbances are beyond the control of the utility. The outage happens but due to many reason. The electricity equipment requires consequently the emergency power supply. We classify the subordinate for quick supply of the emergency power supply and must grope the supply plan. We will find out in this paper through the case study about the emergency power efficient operation plan.

英語 形容詞類 受動分詞에 대한 硏究

홍순서,전창식 순천향대학교 1994 논문집 Vol.17 No.1

Within the framework of the Universal Grammar, differences in the syntactic function of verbs in a language may be attributed to their lexical representation. English passives have been analyzed in two ways; certain passives are lexically derived, where passive verbs exhibit the properties of adjectives; other passives are derived transformationally, where passive verbs undergo syntactic movement. What follows will serve as theoretical backgrounds for subsequent discussion of adjectival passive in English.

古代의 韓ㆍ中ㆍ日 醫藥交流 : 「일본서기」를 중심으로 indicated in 「Ilbonseogi」

신순식,최환수,양영준,홍원식 한국한의학연구원 1996 한국한의학연구원논문집 Vol.2 No.1

『Ilbonseogi』(edited A.D.720) was studied to investigate the medical and pharmaceutical exchange among ancient Korea, China and Japan. It seemed that Korean and Chinese traditional medicine was introduced to Japan through Korea. It was also shown in 『Ilbonseogi』 that Koreans who lived in China and Japan during that time seemed to have active medical idea exchange. From various facts indicated in 『Ilbonseogi』, it was believed that Korean and Chinese traditional medicine was the basis for the foundation of Japanese traditional medicine.

大邱地方의 頭部白癬

徐舜鳳,全在福,金基洪,金仁珠 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

1976年부터 1979年까지 慶北 漆谷카톨릭皮膚科病院에 來院한 外來患者中에서 臨床的 및 眞菌學的으로 頭部白癬으로 確診된 154例에 對하여 觀察한 成積을 다음과 같이 要約한다. 頭部白癬은 總外來患者의 0.19%에 該當하며 1976年부터 1978年까지는 큰 變動이 없었으나 1979年에 갑자기 2~3倍로 增加되었다. 男女의 罹患比는 7歲未滿에서는 큰 差異가 없으나 8~14歲群에서는 男子가, 高年齡群에서는 女子가 높았다. 그러므로 1961年以前에 比하여 男女間에 큰 差異가 없어지고 있다. 總分離菌 136株中 M. canis가 97株(71.3%), T. ferrugineum이 26株(19.1%), T. mentagrophytes가 10株(7.4%), T. rubrum이 3株(2.2%)이었다. 이 成績이 1961年前에 比하여 T. ferrugineum은 1977年부터 顯著히 減少되는 反面에 M. canis가 急增되어 主要菌의 交替現象이 일어나고 있다. T. ferrugineum은 14歲未滿의 男子에 많고 M. canis는 男女 모두 14歲未滿에서 많았으나 特히 女子에서는 7歲未滿과 高年齡群에 많았다. 特히 M. canis感梁이 7歲未滿 兒童에 많았으므로 앞으로 感染源인 고양이의 索出과 이에 對한 適切한 加療가 必要하다. Reports have been made of the detailed clinical and mycological observation on tinea capitis in the Taegu area during the period of 1954 through 1961. There had been, however, no follow-up studies on the disease until 1975. With the reports on the increasing incidence of Microsporum canis infections throughout the country, we suppose that the clinical features and the causative agents of tinea capitis may differ from those observed between 1954 and 1961. The authors observed 154 cases of tinea capitis at Chilgok Skin Clinic during the period from 1976 to 1979, clinically and mycologically. Tinea capitis occupied 0.19% of total outpatients in the clinic, and the incidence increased markedly during 1979. There was no general difference in incidence rates between both sexes of children, but a tendency was noted male children were predominant among the age group of 8 to 14, while female children were predominant among the age groups of under 7 and over 40 years. Among 136 fungi isolated from patients M. canis was most frequently found with 97 (71.3%) strains, and followed by 26(19.1%) of Trichophyton ferrugineum, 10(7.4%) of T. metagrophytes and 3(2.2%) of T. rubrum. These results indicate that T. ferrugineum which was the most predominant agent of tinea capitis before 1962, is decreasing markedly, while M. canis is increasing rapidly as the causative agent. The number of strains isolated in 1979 was more than the total number of strains in 1976 through 1978, showing that the predominance of causative agents in tinea capitis is changing toward M. canis, as compared with the distribution of agents before 1962. T. ferrugineum was frequently isolated from male children under the age of fourteen. M. canis was predominant in both sexes under the age of fourteen, but was predominant among patients under the age of seven and a higher age group in female.

Juvenile polyp, also known as a retention polyp because they contain mucin cysts, is a relatively common hamartomatous lesion in chlidhood. It occurs in 1-2% of children and young adults; however it is uncommon in adulthood. Juvenile polyp is rare in the first year of life and is thus presumed to be acquired and not congenital. It is pedunculated, 2-3 cm in size, red-tan in colour, smooth and always shows fluid filled cystic spaces on cut surface. Histologically, Juvenile polyps are hamartomatous with distended, mucus-filled glands, often with cystic dilatation and edematous lamina propria containing abundant vasculature. The most common manifestation is rectal bleeding produced by auto-amputation of the polyp. Juvenile polyp has been considered not to be at increased risk of developing carcinoma. However, atypical epithelium is observed in some lesions, especially in larger polyps, which may give rise to adenoma and subsequent malignant transformation. Therefore the diagnosis of solitary juvenile polyp should not be made only with colonoscopy and biopsy, but should be totally resected endoscopically for pathologic evaluation. About 90% of the lesions are solitary and localized within 20cm from anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon. We report one case of juvenile polyp in adolescent that presented as a hematochezia & abdominal pain, which is located at right colon.

Purpose : To describe ultrasound(US) and CT findings of primary epiploic appendicitis Materials and Methods : From March, 1999 though Novemer 1999, clinical, US, and CT findings were reviewed in nine patients with primary epiploic appendicitis (eight women and one men, aged 27-54 year[mean, 36 years]). All patients performed US and four patients performed abdominal CT. The main symptoms were rapid onset, localized abdominal pain and tenderness(left lower quagrant pain[n=8], right abdominal pain[n= 1]) Results: US revealed small, ovoid, and mass are echogenic(n=7) or isoechoic(n=2) mass, located anterolateral to the colon. The echopattern of the mass are echogenic(n=7), or isoechoic(n=2). CT performed in four patients shown small oval fatty mass with a thin peripheral rim and central high attenuation area at anterolaeral side of the colon. Some streaky infiltration are associated around the fatty mass. Conclusion: Primary epiploic appendicitis has fairy. characteristic US and CT findings that enable a rapid diagnosis and valuable far differential diagnosit of other condition of acute abdomen.
