        승객용 엘리베이터 와이어로프의 유효수명 및 교체시기 평가

        손두익,박재석,오환섭 한국안전학회 2003 한국안전학회지 Vol.18 No.4

        The wire rope, one of the component of the elevator, is extremely important for the safe operation of the elevator. That is why the wire rope is replaced at a specific interval regardless of the operating conditions or the degree of damage to prevent the breakage of the wire rope. This is the waste of resources, causing economic and environmental loss. This paper has surveyed and analyzed the status of replacing wire-rope by buildings that use elevators, in order tc compare the replacement cycles of the wire rope under each operating conditions.

        하악과두 골절에 대한 임상적 연구

        손보형,이효빈,황호길,윤창륙,여환호 大韓顎顔面成形再建外科學會 1992 Maxillofacial Plastic Reconstructive Surgery Vol.14 No.4

        The author investigated the 162 patients with the condylar fractres of the mandilble who were admitted in Dept. of Oral and Maxillofacial Surgery, Hospital of Chosun Dental School from January 1985 to September 1992 clinically, including fracture incidennce, age and sex of the patients, causes of injures, associated injures, treatments and complications and obtained the following results. 1. Of the 449 patients with mandibular fractures, 162patients suffered condylar fractures(36.1%). 2. Of the 162 patients, males with condylar fractures were 128 patients, by a ratio of 3.8 : 1. 3. The most frequently affected age group was the third decade(32.7%). 4. Falls were ranked as the predominant cause(50.6%), followed by traffic accident(27.8%) and violence (16.0%). 5. The incidence of single condylar fractures was 28% and symphysis fractures were the most commomest of the concomittant injuries(60%). 6. The subcondylar fractures occurred most frequently(41.6%) and anteromedial displacement of the condylar fragments occurred most frequently(45.4%) 7. Of the all condylar fracture patients, children under 15 of age comprized 31 patients(19.1%) and condylar head fractures occurred most frequently at those children. 8. Of the managetments in condylar fractures, open reduction was 52.5% and remainder were closed reduction(47.5%). 9. Complications ensured such as TMJ ankylosis, limitation of mouth opening and mandibular movements, TMJ dysfunction, and anterior open bite.

      • 수영선수의 체격 및 체력이 경기력에 미치는 영향

        손환수,전도선,오성기 釜山外國語大學校 比較文化硏究所 1999 比較文化硏究 Vol.10 No.-

        Abstract This study was attempted to evaluate and quantify the differences of physical fitness among 4 swimming events(free style, back stroke, breast stroke, butterfly). To determine whether the differences among them existed or not the following question was addressed, were winning athletes among the 4 swimming events physically different? When significant differences were found, efforts focused on describing and quantifying the differences. On the basis of results, it is planned to select some physical fitness batteries which could best discriminate the successful swimmers. The 5 physique factors and 6physical fitness tests as discriminators, such as hight, weight, chest girth, upper limb length, lower jump, reaction time, one-legged standing time, vital capacity. The subjects included 60 elite swimmers sample from Pusan swimmers Team. The speed computer programs were used for data analysis. The results as follows: 1. physique In height, the average of male butterfly athletes was 170.0±3.0cm and 161.0±3.8cm for female butterfly athletes. The result of ANOVA test showed a significance difference for both man and woman(P<.05). In body weight, there was a significance difference both in male butterfly athletes(67.0±3.4kg) and back strokes(70.0±8.1kg). In case of woman, there also was a significance difference(P<.001) in case of woman, there also was a significance difference(P<.001) in butterfly athletes(54.7±5.5kg). In chest girth, it showed a 95.6±3.1cm for male back strokers and 83.0±3.3cm for female. Both showed a significance difference(P<.05) in 74.6±1.5cm for male butterfly athletes and 72.0±1.4cm for female back strokers. In lower limb length, the significance difference was found in male, female butterfly athletes and female breasts strokers, female free style. In standing broad jump, both male and female free style section shoed a significance difference(P<.001). In whole body reaction time, there was a significance difference for both female back strokers in light (0.33±0.1sec) and man free style sprinters (0.27±0.02sec) in sound. Here, there also was a significance difference in back strokers. In one-legged standing time, male free style section showed an annual significance difference(42.3±22.6sec. on average). In vital capacity, difference on the level of P<.06 (5,307±411ml on average). This study was attempted to evaluate and quantify the differences of physical fitness among 4 swimming events(free style, back stroke, breast stroke, butterfly). To determine whether the diffemces among them existed or not the following question was adressed, werw winning atheletes among the 4 swimming events physically different± When significant differences were found, efforts focused on describing and quantifying the differences. On the basis of results, it is planned to select some physical fitness batteries wrich could best discriminate the successful swimmers. The 5 physique factors and Gphysical fitness tests as discrimnators, such as height, weight, chest girth, upper limb length, lower jump, reaction time, one-legged standing time, vital capacity.

In lower limb length, the significance difference was found in male, female butterfly athelets and female breasts strokers, female free style. 2. physical fitness In back strengh, there was a annual significance difference (P<.05) for both male butterfly athelets and breasts strokers. In case of woman, there also was a significance difference for both breasts strokers and free style sprinters. In standing broad jump, both male and female free style section shoed a significance difference(P<.001). In whole body reaction time, there was a significance difference for both female back strokers in light (0.33±0.1 sec) and man free style sprinters (0.27±0.02sec) in sound.

      • 自治警察制 導入에 關한 硏究

        신환철,손봉선 全北行政學會 1997 全北行政學報 Vol.11 No.1

        The purpose of this study is to examine localization of the police system in Korea today with emphasis on previous attempts during the last fifty-two years, since the foundation and neutralization several times without any success in the past because they still followed the central government police policy. I believe that the localization of the police system is needed today and must be realized on a basis of necessity. First, We need the local government to be stabilized, police investigation to be independent, and political neutralization. The localization of the police must be achieved in order to realize the democratization of our society. Many people desire the localization of the police force since such localization is already practiced in various other general fields of policy including economy and culture.

      • 학교체제 다양화 정책의 현황과 과제

        이현림,최손환 영남대학교 지역발전연구소 2003 영남지역발전연구 Vol.32 No.-

        본 연구는 획일화된 학교교육에서 벗어나 학교체제를 다양화하고자 하는 교육개혁정책에 초점을 맞춘 것이다. 이에 따라 학교체제 다양화 정책의 추진배경과 목표를 살펴보고, 그 실천으로 나타나는 대안학교, 특성화학교, 자율학교, 그리고 자립형 사립고등학교를 중심으로 각 학교의 특성을 살펴 보았다. 이를 토대로 도출해 본 학교체제 다양화의 성과와 문제점을 앞으로의 학교운영에 있어서 개선점으로 제공하고자 한다. 본 연구의 결론은 학교체제 다양화 정책 시행의 성과와 문제점을 도출하려는 데 있었다. 학교체제 다양화 정책의 시행에 따른 성과는 다음의 세 가지가 있다. 첫째, 교육이 질적 향상이다. 둘째, 학교 운영의 자율권 확대이다. 셋째, 학교 선택의 기회 제공이다. 그리고 문제점으로는 다음의 여섯 가지가 있다. 부족한 규모, 과도한 대학입시 경쟁, 관료주의 행정체제, 계층화의 문제, 개념의 중복과 불분명성 그리고 신자유주의 정책의 문제를 들 수 있다. 교육과 관련된 많은 정책들이 있지만, 어떤 정책이 시행될 때 그것이 아무리 잘 정비되고 현장에 적합한 것이라 할지라도 성과와 문제점이 드러나게 마련이다. 따라서 이러한 성과가 나타났으니 문제되는 부분을 덮어두어야 한다거나, 이러한 문제가 발생되었으니 이 정책은 폐기되어야 한다는 등의 이견만을 강조할 것이 아니라, 보다 나은 정책의 실현을 위해서 어떤 정책의 성과와 문제점을 실험단계, 혹은 시행초기 단계에 고쳐나가고 상호 보완해야 할 것이다. 이것이 바로 우리가 보다 나은 교육현장을 만들어 나가기 위해서 가장 기본적으로 가져야 할 자세일 것이다.
