정신연습이 고등학교 사격선수의 기록과 불안수준에 미치는 영향
전용태 한국학교체육학회 2000 한국학교 체육학회지 Vol.10 No.1
본 연구의 목적은 정신연습이 고등학교 사격선수들의 사격기록과 불안감소에 미치는 영향을 파악하고, 최상의 기록을 내는데 필요한 적정 불안수준을 밝히는데 있다. 이러한 연구목적을 달성하기 위해서, 32명의 고교사격선수들이 임의로 선정되었고 각각 16명씩 통제집단과 실험집단에 무선 할당되었다. 실험집단은 신체연습관 정신연습을 병행하였고, 반면에 통제집단은 단지 신체연습만을 실시하였다. 실험집단은 8주 동안 하루에 40분씩 근육이완훈련, 심상훈련, 시청각 교육 등을 받았다. 본 연구를 통해 얻어진 결과는 다음과 같다. 1. 정신연습은 사격기록을 향상시키는데 효과가 있는 것으로 나타났다. 2. 정신연습은 불안수준을 감소시키는데 약간의 효과가 있는 것으로 나타났다. 3. 사격의 불안수준 일정한 범위 내에 집중되어 있으나, 그 범위가 넓은 것으로 나타났다. The purpose of this study was to find cut the effect of mental practice on shooting record and anxiety, to optimal anxiety level on shooting. In order to pursuited this purpose, 32 Highschool shooting elite players were selected as subjects who were randomly devided into 2 groups. Each of group consisted of 16 boys. The first group was physical and mental practice, the second group for physical practice only. Experimental group practiced 40 minute a day for 8 weeks which was muscle relaxation training, imagery training, video-instruction and audio-instruction. To measure shooting record and anxiety level, that were used the point allotted to subjects when a ball struck a target and this were used heart checker. In optimal level, were used which subjects struck to 9, 10score only. After finishing practice, shooting record and anxiety level was retested. The results of this study were; 1. Mental practice was e91c1ive on the development of shooting record. 2. Mental practice was a few effective on the decrease of anxiety level. 3. Anxiety level of shooting concentrated to regular range.

Polygon–based 3D Surgical Planning System for Hip Operation
전용태,박세형 한국정밀공학회 2011 International Journal of Precision Engineering and Vol. No.
This paper presents a light-weight software system that enables virtual three–dimensional (3D) surgical planning of hip replacement surgery for extracting 3D surgical parameters such as the position and the orientation of femoral resection plane, the interference–free trajectory of prosthesis implantation, and the final assembled position. According to the specification of an individual patient, the system allows the surgeon to design a hip prosthesis that most closely recovers the original function of the joint. Since it is based upon the 3D anatomy, the system overcomes a geometrical mismatch between prosthesis–bone interfaces which is the main limitation of 2D–based approach. The closely customized prosthesis–bone fit appears to increase the durability of hip prosthesis, and enhances the load distribution and the stability. Detailed steps of the system are described, and typical example is presented to validate the methodology. The result shows that the proposed pilot surgical planning system is applicable.

전용태,김문귀 한국재난정보학회 2015 한국재난정보학회 논문집 Vol.11 No.4
With about 75% of the population of Korea criticizing the government's disaster policy and a failure to respond to large-scale emergency like the Sewol ferry sinking means that there is a deep distrust in the government. In order to prevent dreadful disasters such as the Sewol ferry sinking, it is important to secure a prime time with respect to disaster safety. Improving crisis management skills and managerial role of police officers who are in close proximity to the people is necessary for the success of disaster management. With disaster management as one of the most essential missions of the police, as a part of a national crisis management, a step by step strengthening of the disaster safety management system of the police is necessary, as below. First, at the prevention phase, law enforcement officers were not injected into for profit large-scale assemblies or events, but in the future the involvement, injection should be based on the level of potential risk, rather than profitability. In the past and now, the priortiy was the priority was on traffic flow, traffic communication, however, the paradigm of traffic policy should be changed to a safety-centered policy. To prevent large-scale accidents, police investigators should root out improper routines and illegal construction subcontracting. The police (intelligence) should strengthen efforts to collect intelligence under the subject of "safety". Second, with respect to the preparatory phase, on a survey of police officers, the result showed that 72% of police officers responded that safety management was not related to the job descriptions of the police. This, along with other results, shows that the awareness of disaster safety must be adopted by, or rather changed in the police urgently. The training in disaster safety education should be strengthened. A network of experts (private, administrative, and police) in safety management should be established to take advantage of private resources with regard to crisis situtions. Third, with respect to the response phase, for rapid first responses to occur, a unified communication network should be established, and a real-time video information network should be adopted by the police and installed in the police situation room. Fourth, during the recovery phase, recovery teams should be injected, added and operated to minimize secondary damage. 국민의 75%가 정부의 재난관리 정책을 비판하는 등 세월호 참사와 같은 대형 재난 관리 실패는 정부 불신을 초래하고 있다. 세월호 참사와 같은 재난이 다시 발생하지 않도록 재난 안전에 있어 골든타임 확보가 중요하며, 주민의 가장 가까운 곳에 위치한 경찰의 재난 위기관리 능력 개선이 필요하다. 재난 안전 역시 경찰 임무의 본질로서 다음과 같이 국가위기관리 단계별로 경찰의 재난안전 관리 시스템의 강화가 필요하다. 첫째, 예방단계에서는 과거 다중운집행사의 경우 수익성 행사의 경우 경찰력을 투입하지 않았으나, 앞으로는 기준을 수익성이 아닌 위험성 여부로 판단해야 한다. 그동안 교통 소통이 우선이었으나 안전 중심으로 교통 정책의 패러다임을 전화하고, 대형 사고를 예방하기 위해 수사 경찰은 비정상적 관행과 건축불법 하도급을 근절하며, 정보 경찰은 ‘안전’이라는 주제에 대한 정보 수집을 강화해야 한다. 둘째, 대비단계와 관련 최근 경찰관 대상 설문 조사 결과 경찰관의 72%는 안전관리와 경찰이 업무연관성이 없다고 응답하는 등 재난안전에 대한 인식도 개선이 시급하므로 재난 안전 교육 훈련을 강화해야 한다. 위기상황에 대한 민간 자원을 활용할 수 있도록 민ㆍ관ㆍ경 재난 안전 네트워크를 구축해야 한다. 셋째, 대응단계에서 신속한 초동 대응을 위해 재난 통신망을 일원화하고, 경찰기관 상황실에 실시간 영상정보망을 도입해야 하며, 넷째, 복구단계에서는 2차 피해를 최소화하기 위한 복구지원팀을 운영해야 한다.

전용태,임은하 (사)한국CDE학회 2016 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2016 No.동계
This paper presents a method to evaluate the biomechanical stability of the patient-specific total hip implant using a three-dimensional finite element analysis within the proximal femur. 2000 N of load was assigned to the femoral head. With a FEM tool, the stress distribution on the designed prosthesis was well simulated. Detailed steps of the whole process are described, and typical example is given and discussed. This study can be applied to evaluate patient-specific hip implant in biomechanical stability point of view.
