  • 저독성 폴리올레핀 절연재료, Sheath재료의 저독성, 연기밀도특성, 연소가스부식성 분석을 하기 위하여 저독성 내화케이블의 성능평가 시험을 수행하였다. 화재 발생시 화염확산 및 유독성가스발생의 주원인으로 피난안전계획에 매우 중요하다. 90년대 후반기부터 연이어 발생한 씨랜드 화재사고와 인천 인현동 라이브클럽등의 동일한 유형을 가진 화재사건을 계기로 국내 내화케이블에 사용되는 재료가 화재시 인명참사에 미치는 영향이 크다는 점이 발견되었다. 본 연구에서는 고체물질에서 발생하는 연기의 특성광학밀도를 ASTM E662를 근거로 하여 실험을 하였다. 전기로의 시스템은 20분동안 밀폐된 챔버내에서 2.5$\pm$0.04w/$\textrm{cm}^2$을 지닌 조사열량을 일정한 상태 하에서 방사를 유지할 수 있도록 하였다. NFR-8과 FR-PVC 연기밀도의 분해 결과에 따라 완전연소에 의한 연기밀도 최대값 NFR-8은 25.2에서 39.6 FR-PVC에서 51.1의 값을 얻을 수 있었다. 비연소 열분해에 의한 연기밀도 최대값 NFR-8은 100.4에서 112.2 FR-PVC는 126.5에서 398.8의 값을 얻을 수 있었다. 또한 시료의 연기밀도 분석결과 PVC가 폴리올핀 시료보다 상당히 많은 양의 CO가 발생되는 반면 $CO_24의 양은 적게 발생하였다.

  • 현재 시판중인 대부분의 음료가 산성을 띤다는 사실은 이미 잘 알려져 있으며 이러한 산성의 음료 음용의 증가는 우려할 만한 수준으로 치아 침식증을 촉진할 것으로 생각된다. 따라서 본 연구는 어린이들이 비교적 일상적으로 쉽게 접하는 탄산음료 중 가장 보편화된 한 종을 택하여 치아와의 노출과 노출빈도에 따른 법랑질의 침식정도를 조사 분석할 목적으로 시행되었다. 탈락 시기의 건전한 유치를 발거하여 두 개의 군, 즉 magnetic stirrer에 의해 진동(agitation)을 받은 군과 그렇지 않은 군으로 나뉘었고 나뉜 군들은 또 각각 콜라에의 노출빈도에 따라 3개의 군으로 나뉘었다. 각각의 군들은 신선한 콜라에 5분씩 노출되었으며 노출 전과 후에 증류수에 의해 세척되었고 시편의 노출이 이루어지지 않는 시간에는 생리 식염수에 보관한 후, 인공적으로 침식을 유발시켰을 때 나타나는 양상을 표면미세경도측정법으로 분석하여 다음과 같은 결론을 얻었다. 1. 본 실험에 사용된 콜라의 산도는 평균 pH 2.5로서 치아 침식증을 유발하기에 충분한 수준이었다. 2. 콜라에 의한 침식유발 후의 법랑질 표면경도는 대조군에 비해 모든 시료에서 감소되었다(p<0.05). 침식유발 시간이 경과함에 따라 법랑질 표면경도는 모든 실험군에서 초기에는 급격히 낮아지다가 이후에는 그 정도가 덜해지는 양상을 보였다. 3. 법랑질을 콜라에 노출시킨 빈도가 증가함에 따라 법랑질 표면경도는 감소되었다. 4. 콜라에 진동(agitation)을 가하여 탄산가스를 증가시킨 결과 법랑질의 표면경도는 진동을 가하지 않은 군에 비해 감소되었다(p<0.05).

  • Purpose: The purpose of this qualitative study was to understand the application of clinical reasoning throughout clinical and therapeutic knowledge of clinical pediatric physical therapists under physician prescriptions. Methods: Purposive sampling techniques were used in selection of nine clinical pediatric physical therapists in South Korea. Open and semi structured interviews were conducted, and were thoroughly examined and reviewed, followed by analysis of the clinical reasoning portion. Results: Pediatric physical therapists have been influenced by information gathering, physical function and evaluation of their patients, hypothesis-orientation, and re-evaluation and self-monitoring. Novice physical therapists were more dependent on physician prescriptions and parent's hope than the result of their own evaluation and critical pathway. Middle experienced pediatric physical therapists were more dependent on rapport with children and their parents. Highly experienced pediatric physical therapists were more reliant on hypothesis-orientation and self-monitoring. As reports on clinical experience of pediatric physical therapists have accumulated, clinical reasoning of pediatric physical therapists has been influenced by their experience, such as education, clinical pathology conference, their own clinical experience and rapport with patients and their parents than physicians' prescriptions. Conclusion: The findings of the current study are generally consistent with existing research on clinical reasoning. The results of the current study may be used by educators for enhancement of clinical reasoning abilities and knowledge of students or novices as well as development of a guide for use by suitable novices or students, and could provide important information for use in physical therapy practice and research.

  • Purpose: Prior to closure of the epiphysis of the distal phalanx, fracture usually occurs through the growth plate, Salter-Harris type I or II, or through the juxtaepiphyseal region 1 to 2 mm distal to the growth plate. The terminal tendon of extensor inserts into the epiphysis only, while insertion site of the flexor digitorum profundus spans both the epiphysis and metaphysis. Because of the difference between these tendon insertions, this injury mimics a mallet deformity. But, this type of injury does not involve a tear or avulsion of the extensor, unlike mallet finger of adults. Seymour was the first to describe this type of injury in children and called after his name, Seymour's fracture. This fracture is prone to infection or remain the residual deformity unless adequate treatment. Methods: We report a case of Seymour's fracture. A 9-year-old boy presented a laceration of the nail matrix, with the nail lies degloved from the nail fold on the right middle finger gotten from an impact against a door. An X-ray examination showed the fracture line lying 1 mm distal to the growth plate. The injury was treated with debridement and the fracture was reduced by applying hyperextension force. Under the C-arm, a single 0.7 mm K-wire was used to immobilize the distal interphalangeal joint. Intravenous antibiotics were applied for 5 days after surgery. Results: The K-wire was removed in the 3rd week. No infection or significant deformity was found until follow-up of 12 months. Conclusions: Seymour's fracture may be at first classically mallet deformity by its appearance. But it is anatomically different and more problematic injury. If it isn't corrected at the time of injury, derangement of the extensor mechanism, and growth deformity of the distal phalanx may occur. The fracture site should be debrided, removed of any interposed soft tissue, and the patient should be given appropriate antibiotics. Reduction should be maintained by K-wire fixation. We experienced no infection or premature epiphyseal closure.

  • Comedy costumes worn on the comedians/gag men express the information of the performances such as character's era, place, social rank, present environment, age, sex, occupation, emotion, relationships between the characters, importance and mood in visual language. The comic is found when these informations are reversed, revealed, exaggerated or distorted. To analyse the TV comedy costumes, 5 subordinate concepts of the comic which are Body, Gender, Age, T.P.O.(Time, Place, Occasion) and Role could be identified, and the results from the analysis focused on (10 shows were selected from each of the first and second half of the years from 2003 to 2007) are as follows: Distorted and ugly body implies the resistance against the ideal body. Reversed or confused sex are usually expressed as men dressed in women, and these mean breaking the dichotomy between male and female, and coexistence of the masculinity and feminity, and satirizing the social custom restricting women by moral rules. It could be recognized that the way of men's dressing in women have been changing keeping pace with the times. The discord between age and costume was often expressed with children's wear and childish props. This implies the liberation from the age role. The comic expressed from the inadequate costume for T.P.O. usually appeared with the costumes 20-30years behind the times. When there were discordance with the acts and acts expected from the outfit(appearance) also made an ironical laugh. The comics acquired by vulgarization and exaggeration of the characteristics of role(figures/occupation) were from the imitation and deformation of the objects in stereotypes, and through this dissolving the custom was under way.
