  • Nowerdays, the increase of traffic accidents and old age population make the Femoral Neck Fracture(FNF) patients increase. By the improvement of education and standard of living the patients demand better medical service than before. This study is designed to give practical help for the FNF patients by observing their hospital life and establish practical nursing strategies for the FNF patients. For these purposes the Ethnographic Participant Observation was adopted. By this study is focused on the hospital life patient's view. For this end, the field study adopted orthopedic ward in the C University Hospital with 400 beds in Seoul. The object patients of the study were twelve patients. The patients experienced five stages : Embarrassment, Conflict, Stability, Independent, and Extension Stage. The findings and prepared nursing strategies are stated as follows. First, in the Embarrassment Stage they suffered embarrassment, anxiety, pain, they could not do ordinary things. The patients who accidental fractures had anxiety from unfamiliar tests and from hospitalization itself. They lamented that they could not ordinary things, and do nothing but obeying the hospital, and endure the pain. They recognized the changed environment and resigned themselves to life in the ward. In this stage, full openness by the nurses is needed. Second, the attribute of the Conflict Stage were conflict, fear, curiosity, belief, reflection. When they sign the consentment form, they experience conflicts about the possibility of complication, fear of recovery from anesthesia, curiosity about the operation procedure, post - operation state, reflection on their past life, and promise to care for their family members after discharge and keep their religious life faithfully. And they accepted the operation depending on God, believing in modern medicine, and the surgeon. Asking for their changed informations, they expected positive results from the operation. In this stage, an empathic attitude by the nurses is needed. Third, the attribute of the Stability Stage were relief, gratitude, difficulty with excretion, and pain. When they awoke from anesthesia, they felt relief because of a the end of the operation, but they experienced extreme pain, difficulty of excretion in bed. They accepted the changed environment and expected recovery. In this stage, support by the nurses is needed. Fourth, the attributes of the Independence Stage were freedom, exercise, nurturing, anxiety, and discomfort. When they ambulated and exercised, they experienced freedom. They showed exhibited weakness of the digestive organs and discomfort hospital's space, structure, and facilities, the delay of medical certificate issue the lack of prompt response by the medical agents. They ate nurturious food and felt anxiety on the end of hospital life and returning to their ordinary life. They showed the independence of overcoming their environment by increasing exercise and expected their discharges. In this stage, respect by the nurses is needed for the patients to, overcome their environment and prepare for their independence. Fifth, the attributes of the Extension Stage were pessimism, isolation, dissatisfaction, and pain. Accompanied injury and old age made their ward life extend to over seven weeks. They exhibited weariness, melancholy, skeptisis, general pessimistic feeling, and desperation caused by their isolated life. They experienced the digestive discomfort caused by the prolonged medication and psycological pain caused by long-time hospitalization. As a, result, their dissatisfaction on the human, physical, and systematic environments had been increased. They acquired critical power and sought for something to do spending their time. They expected vaguely about the returning of their ordinary life. In this stage, counseling is needed by the nurse to overcome positively their psychological, social, and physical problems. The process of the FNF patient's ward life starts from the dependent state, when they are hospitalized, and gradually progresses to self-fulfillment in order to keep independent life. As a result, the FNF patients showed "Response in Challenge" or "Adaptation in Conflict" through their experiences of social, physical, and psychological difficulties.

  • Objective : We analysed various surgical approaches and surgical results of 28 middle cranial base tumors for the purpose of selecting optimal surgical approach to the middle cranial base tumor. Methods : In this retrospective review, 28 patients, including 16 meningioma, 6 trigeminal neurinoma, 2 pituitary adenoma, 2 craniopharyngioma, 1 facial neurinoma, and 1 metastatic tumor, underwent surgical treatment using skull base technique. Of theses, 16 tumors were mainly confined to middle cranial fossae, 5 tumors with extension into both anterior and middle fossa, and 7 tumors with extension into both middle and posterior fossa. Tumors that confined to the middle cranial fossa or extended into the anterior cranial fossa were operated with modified pterional, orbitozygomatic or Dolen'c approach, and tumors that extended into the posterior cranial fossa were operated with anterior, posterior or combined transpetrosal approach. Completeness of tumor resection, surgical outcome, postoperative complication, and follow up result were studied. Results : Total tumor removal was achieved in 9 tumors of 10 tumors that did not extended to the cavernous sinus, and was achieved in 7 tumors of 8 tumors that extended to the lateral wall of the cavernous sinus. Of 10 tumors that extended to the venous channel of the cavernous sinus, only 2 were removed totally. Surgical outcome was excellent in 14 patients, good in 10, fair in 2 and poor in 2. There were no death in this series. Dumbell type tumor which extended into both middle and posterior fossae showed tendency of poor prognosis as compared with tumors that confined middle cranial fossa and extended into both anterior and middle cranial fossa. Postoperative dysfunctions were trieminal hypesthesia in 3, oculomotor nerve palsy in 2, abducens nerve palsy in 2, hemiparesis in 2, cerebellar sign in 1, facial palsy in 1 and hearing impairment in 1. Conclusion : Based on our findings and a review of the literature, we conclude that, when selecting the surgical approach to the middle cranial fossa tumors, the most important factors to be considered were exact location of the tumor mass and existence of the cavernous sinus invasion by tumor mass. We recommend modified pterional or orbitozygomatic approach in cases with tumors located anterior and middle cranial base, without cavernous sinus invasion. In cases with tumors invading into cavernous sinus, we recommend Dolen'c or orbitozygomatic approach. And in lateral wall mass and the cavernous sinus, it is preferred to approach the tumor extradurally. For the tumor involing with middle fossa and posterior fossa(dumbell type) a combined petrosal approach is necessary. In cases with cavernous sinus invasion and internal carotid artery encasement, we recommend subtotal resection of the tumor and radiation therapy to prevent permanent postoperative sequele.

  • 우리나라는 교통안전법에 의해 지역교통안전기본계획을 수립 시행하고 있다. 지자체별 맞춤형 교통안전시책 수립을 통해 교통안전 향상을 위한 대책 수립 및 역할분담이 강조되고 있으며, 이는 곧 지자체가 지역실정에 맞는 내실 있는 지역교통안전 정책을 실질적으로 주도하여 추진하는 것을 의미한다. 지자체들이 가지고 있는 다면적인 특성에 부합되는 효율적인 교통안전정책이 시행되기 위해서는 지역특성을 고려한 지역단위 교통사고를 예측하고 사고에 미치는 영향요인 분석이 선행되어야 하지만 이에 대한 연구는 미흡한 실정이다. 지역을 기반으로 하는 교통사고 예측에 관한 기존 연구들은 자료 수집의 한계로 대부분 국가 또는 도시를 분석단위로 사고노출환경과 관련되는 사회경제변수들을 활용한 연구가 대부분이었다. 교통사고 예측모형을 개발하는 이유는 교통사고 발생특성을 파악하여 교통사고를 줄일 수 있는 효율적인 대책을 발굴하는 것이 주요 목적이다. 이에 본 연구에서는 기존연구에서 다루지 못한 보다 작은 지역단위인 행정동을 단위로 지역교통사고 예측모형을 개발하였으며, 사고 노출환경 측면의 사회경제적 변수 외 교통안전정책가가 제어할 수 있는 교통안전시설 및 정책변수를 모형에 반영하여 지역교통안전 정책 수립시 활용할 수 있는 방안을 제시하였다. 모형개발 결과 사고노출환경 측면에서는 도로연장, 건축물 총 연면적, 버스전용차로 설치율, 교차로 및 횡단보도 개소수는 사고와 양(+)의 관계를 보이고 있으며, 횡단보도예고 설치율, 과속방지턱 개소수 및 경찰인력에 의한 단속실적은 사고와 음(-)의 관계에 있는 것으로 나타났다.

  • 개의 치수에 MTA, calcium hydroxide 및 calcium sulfate로 치수복조 후 치수 반응을 서로 비교하여 MTA와 calcium sulfate가 임상적으로 치수복조제로서 사용 가능할 것인가를 구명하고자 본 연구를 시행하였다. 8개월 된 2마리 개의 24개의 치아가 본 연구에 사용되었다 전신 마취하에 고속 핸드피스를 사용하여 멸균된 #2 round bur로 치경부에 와동을 형성한 후 치수를 노출시켰다. MTA, calcium hydroxide 및 calcium sulfate를 치수노출부에 도포하였다. 와동 부위는 IRM으로 가봉하고 광중합레진으로 수복하였다. 처리 2개월 후, 전신 마취하에 희생시킨 후 조직학적으로 관찰하였다. MTA처리군에서는 치수 노출부위에 경조직의 상아질교가 형성되었으며 새로 형성된 상아질교 하방에 조상아세포가 새로 형성되었다. 치수충혈과 함께 국소적 인 혈관 증식 이 나타났으며 치수에 염증반응은 나타나지 않았다. Calcium hydroxide로 처리한 군은 상아질교 하방에 조상아세포가 관찰되지 않았으며 만성 염증반응이 다양하게 나타났다. Calcium sulfate로 처리한 군은 경조직의 상아질교가 관찰되었으며, 상아질교 하방에 조상아세포 층이 새로 관찰되었다. 몇몇의 중성구 침윤과 함께 미약한 정도의 만성염증반응이 관찰되었다. 이상의 결과에서 MTA가 calcium hydroxide및 calcium sulfate에 비해 치수에 생체친화적임을 시사하며 기계적 치수노출시 치수복조제로 사용할 수 있음을 시사한다.
