An experimental study of the tensile bonding strength of acrylic bone cement was carried out by using the tubular bones of 12 mongolian dogs. Following observations were made: 1. The later the cementing stage, the weaker was the tensile bonding strength of bone cement. 2. When saline or synovial fluid was interposed between the contact surfaces of the recipient bone and the cement, the tensile bonding strength of bone cement decreased by more than 50% of that when the bonding surface was dry. 3. When the bonded bone was stored in Hartmans solution, the tensile bonding strength of bone cement was reduced to 15–25% of the strength when stored in air.

BACKGROUND: The present study was performed in order to identify the possible future location of the Department of Emergency Medicine and future demand for and supply of manpower through a survey of the heads of Kwangju City and Chollanam-do hospitals. The survey covered the degrees of recognition and understanding, the necessity, the future prospects, and the direction of development of the Department of Emergency Medicine. METHODS: A total of 33 large-scale general hospitals were selected in county districts having more than 200 sickbeds as of November 1999. Among them, the heads of 29 hospitals responded to the survey. The survey had a total of 31 questions, including 6 questions on the status of the emergency room. Six(6) questions concerned the degree of recognition of the Department of Emergency Medicine. Six(6) questions concerned the degree of understanding of the Department of Emergency Medicine. Six(6) questions concerned the necessity for the Department of Emergency Medicine, and 7 questions concerned the future prospects and direction of development. The results of the survey were analyzed. RESULTS: 1) As to the question of the degree of recognition, the Department of Emergency Medicine was known to all. That is, 50% of the respondents were well aware of the department, and 50% a little. Nineteen(19) respondents(65%) answered that it was convenient to have the Department of Emergency Medicine in a university hospital, among which 16 respondents(55%) answered that it was because of the rapid treatment of emergency patients. 2) As to the question of the degree of understanding, particularly, the areas of medical examination and treatment by the Department of Emergency Medicine, 15 respondents answered that it was for the treatment of patients who needed to receive emergency treatment, while 12 respondents answered that it was for the diagnosis and treatment of all patients who visited the emergency room. Only 7 respondents(24%) answered positively as to the possibility of the Department of Emergency Medicine using thrombolysis medicine. 3) All except for one respondent had a positive view on the necessity for the Department of Emergency Medicine, and all except for 3 respondents wanted to have specialized doctors in emergency medicine work at the corresponding hospital. As to the type of schedule, 10 hospitals(34%) wanted to have only night shifts, and 11 hospitals(38%) wanted to have both day and night shifts. Most hospitals, needed two or more workers in the field. 4) As to the question of the direction of development, many respondents were of the opinion that the hiring of specialized doctors in emergency medicine would not be of greatly help to the finances of the hospital due to increased labor costs. It seems that improvement of the medical system to improve hospital financing is a required prerequisite for the development of the Department of Emergency Medicine. Also, 21 respondents(83%) were of the opinion that it would take a considerable amount of time to activate the Department of Emergency Medicine with respect to the future prospects of the department. CONCLUSION: It was shown in the present survey that the heads of hospitals in Kwangju City and Chollanam-do recognized the Department of Emergency Medicine in a positive way, but it was necessary to establish both a delivery system for emergency medicine and collaboration with and support by other medical areas for its future development. It was estimated that in the future, more than 55 doctors specializing in emergency medicine would be needed as medical manpower for the general hospitals in the districts.

Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent cessation of breathing due to complete or partial upper airway occlusion during sleep. The incompetent tone of palatal, pharngeal, and glossal muscles which fail to maintain airway patency during sleep causes narrowing of the airway dimension and increased resistance of breathing. The identification of the sites of upper airway obstruction in patients with OSA is important in understanding the pathogenesis and deciding the treatment modality of snoring and/or OSA. Various upper airway imaging modalities have been used to assess upper airway size and precise localization of the sites of upper airway obstruction during sleep. Dynamic imaging modalities enabled assessment of dimensional changes in the upper airway during respiration and sleep. This article focused on reviews of various upper airway imaging modalities, especially dynamic upper airway imaging studies providing important information on the pathogenesis of OSA.
