It is very important to form stable back bead and improve productivity in middle-thick plate butt joint welding of a ship or steel structures. Presently many overlay welding processes associated with plasma arc welding has been developed, but development of processes related to plasma keyhole welding is very run short. Therefore, welding process is especially needed to form stable back bead without backing bar and improve productivity simultaneously in middle-thick plate butt joint welding of a ship or steel structures. The purpose of this study is to develop a plasma-MAG tandem 1pass welding process for middle-thick plate Y-groove butt joint, reducing process, forming back bead and improving productivity.

A new interactive computer program for design and examination of automobile transmission gear is developed. The design data of a shifted helical gear sets are calculated and the contact ratio and the strength condition are examined. The involute curve and a root fillet of the designed tooth profile are graphically presented, and the information for tooth profile such as root point, weakest point, etc. are obtained. The whole engaging gear shape and contact state are certificated in Autocad. To check the lubrication conditions, the minimum film thickness is calculated and compared with the surface roughness data. Therefore the computer program made in this paper gives more improved practical tool in designing an automobile gear set.

이영근,문영재,이준모,Lee, Young-Keun,Moon, Young-Jae,Lee, Jun-Mo 대한미세수술학회 2011 Archives of reconstructive microsurgery Vol.20 No.2

Purpose: The subcutaneous pocket graft of the thumb tip amputation across or proximal to the lunula is chosen in case of impossible microvascular anastomosis and in patient who strongly desired to preserve the thumb tip after failed replantation. Materials and Methods: Two patients who underwent a subcutaneous pocket graft for a thumb tip reconstruction between August 2008 and November 2009 were reviewed retrospectively. They were all males with a mean age at the time of surgery of 48 years and had sustained complete thumb tip amputations across or proximal to the lunula. In one case, the microsurgical replantation was not feasible and the other one revealed arterial insufficiency at the 7th day after microsurgical replantation. Results: Authors had experienced 2 cases of flaps which survived completely. The results of sensibility was good, the range of motion at interphalangeal joint and tip to tip pinch was acceptable and color mismatch and loss of thumb finger nail was unacceptable after more than 1 year follow up with conventional successful thumb tip replantation. Conclusion: The subcutaneous pocket graft could be chosen in thumb tip amputation in case of impossible microvascular anastomosis as well as who strongly desires to preserve thumb tip after failed replantation.

태권도 도장경영에 있어 유아수련생들에 대한 교육현장 실태 보고

강은석(Kang, Eun-Suk),문영재(Moon, Young-Jae),허승은(Hur, Seung-Eun) 한국무예학회 2021 무예연구 Vol.15 No.2

본 연구는 저출산으로 인해 태권도 도장경영의 수요층인 아동 청소년이 감소함에 따라 태권도 교육이 유아로 확대되고 있는 실정에서 과연, 유아수련생들이 태권도 교육을 제대로 받을 수 있을지 의문을 가지고 시작되었다. 이에 본 연구에서는 법적기준 유아라 명하는 만 5세를 제외하고 만 3세부터 만4세 유아수련생들을 대상으로 태권도의 정신적, 기술적 교육이 어떻게 이루어지고 있는지 현장을 통해 실태를 확인하는 작업을 시도하였다. 연구방법은 연구대상자들이 다수 교육받고 있는 두 곳의 도장에 참여관찰과 해석적 및 추론적 면담을 통해 결과를 나타내고자 하였으며 참여관찰이 마무리된 후에는 Spradley의 DRS 기법으로 연구참여자들의 재면담 과정에 참여관찰 결과의 진실성과 신뢰성을 높였다. 연구결과는 크게 세 가지로 나누어 확인되었는데 첫째는, 유아수련생들의 특징으로서 입관동기와 현장에서 일어나는 현상으로 나타났다. 둘째는, 유아수련생들과 지도자로서 불분명한 훈계와 지도사이, 그리고 불분명한 놀이와 수련사이로 확인되었다. 셋째는, 유아수련생들의 교육으로서 교육이라 쓰고 보육이라 읽음과 교육방식 변화 필요성 인지와 현실의 어려움으로 도출되었다. 이에 본 연구를 통해 수련층이 유아수련생으로 확대되는 시점에서 보육과 교육 사이에 고민하는 일선 지도자들에게 유용한 참고자료가 되길 바란다. This study began with the question of whether early childhood trainees will be able to receive taekwondo education properly at a time when taekwondo education is expanding to early childhoods as low birth rates have reduced the number of children and adolescents who are in demand for taekwondo. In this study, we attempted to check the status of Taekwondo"s mental and technical education for children aged 3 to 4 years old, except for those aged 5 who are called early childhood by legal standards. The research method was intended to show results through participatory observations and interpretive and reasoning interviews with leaders, and after the participation observation was completed, the participation observation results were improved with Spradly"s DRS technique. The findings were largely identified in three broad categories. First, it was seen as a characteristic of early childhood trainees, which was the motivation for admission and the phenomenon that took place in the field. Second, it has been identified as unclear discipline and guidance as early childhood trainees and leaders, and unclear play and training. Third, as an education for early childhood trainees, it is written as education and read as child care. Recognize the need for changes in education methods. However, the reality showed difficulties. Therefore, we hope that this study will be a useful reference for front-line leaders who are agonizing between childcare and education at a time when early childhood trainees are expanded.

하위경추 손상 환자의 손상기전에 따른 분석

송경진(Kyung-Jin Song),문영재(Young-Jae Moon),이광복(Kwang-Bok Lee) 대한정형외과학회 2012 대한정형외과학회지 Vol.47 No.4

목적: 하경추부 손상의 수술적 치료 결과에 대한 한국의 많은 수의 환자에 대한 장기간의 수집자료가 없어 이의 빈도 및 치료결과를 분석하고자 한다. 대상 및 방법: 1994년 5월부터 2008년 10월까지 하경추부 손상으로 수술적 치료를 받은 277명을 대상으로 하였다. Allen 분류를 이용하였고, 신경학적 손상 정도를 구분하였으며, 수술 후 합병증, 신경학적 회복, 통증의 회복정도를 분석하였다. 결과: 신연신전 손상이 140명(50.5%)으로 가장 높았고, 완전 척수 손상 46예(16.6%), 불완전 척수 손상 154예(55.6%), 신경근 손상 32예(11.6%)로 신경학적 손상은 모두 232예(83.8%)에서 나타났다. 신경학적 회복은 신연신전 손상(distractive-extension)의 불완전 척수 손상에서 가장 낮은 가용성 회복률을 보였다, 임상적 회복은 술 전 visual analogue scale에 비해 최종추시 시 회복되었다. 합병증으로는 호흡부전, 신경인성 방광, 요로감염, 위염이 발생하였다. 결론: 기존의 보고와 다르게 신연신전 손상이 가장 높게 발생하였고, 이 형태에서 높은 신경학적 손상 발생 빈도를 보였다. 이는 과거 Allen 분류가 단순 방사선 사진에 의해 분류되었기 때문에 자기공명영상에 의한 연부조직손상평가가 필요하리라 생각한다. Purpose: To analyze the incidence and treatment outcomes of lower cervical spine injury since there is no long term, large Korean data available. Materials and Methods: We analyzed 277 patients with lower cervical spine injury who underwent surgical treatments between May 1994 and October 2008. The injury types are based on Allen"s classification, and neurologic injury was classified as complete, incomplete cord injury, root injury and no neurologic status. We analyzed postoperative complications, neurologic recovery and the relief of pain. Results: Distractive-extension injury occurred most commonly in 140 patients (50.5%). Neurologic injury was detected in 232 cases (83.8%); 46 (16.6%) complete cord injury; 154 (55.6%) incomplete cord injury; and 32 (11.6%) root injury. Incomplete cord injury of distractive extension injury was poorly recovered. Clinical outcomes demonstrated improvement compared with the preoperative values in mean visual analogue scale. Complications were respiratory failure, neurogenic bladder, urinary tract infection and gastritis. Conclusion: This study showed the highest incidence of distractive extension injury and neurologic injury contrary to previous studies. This result was caused by the use of plain radiograph to establish Allen"s classification in the past. Therefore, we suggest the use of magnetic resonance imaging for evaluating soft tissue injury with Allen"s classification to achieve accurate assessment.

This paper introduces the IN-FLEX system using aluminum clad flex cable, which is expected to alternate the conventional wiring method, such as, a steel pipe wiring method, and a synthetic resin pipe wiring method. The aluminum clad flex cable has a superior operation characteristics in heat dissipation property, in installation and maintenance facility, flammability, and appearance. Moreover, the IN-FLEX system adopted an easy connection mechanism which enable to reduce the time, hands and expense for the installation and maintenance of the system. Certification tests verifying the superior operation characteristics and reliability of the system using aluminum clad flex cable were carried with standard method in KOLAS certification institute.

The design data of a shifted helical gear sets are calculated and the contact ratio and the strength condition are examined. The involute curve and a root fillet of the designed tooth profile are graphically presented, and the informations for tooth profile such as root point, weakest section point, etc. are obtained.

To check the lubrication conditions, the minimum film thickness is calculated and compared with the surface roughness data. Therefore the computer program made in this paper gives more improved practical tool in designing a automobile gear set.
