The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice 표 instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min. correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=0...) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).

密度高度의 適用에 關한 考察

李晶模,朴溶寒 한국항공대학교 1985 論文集 Vol.23 No.-

Although most of the aircraft pilot understand that the accurate and practical flight performance can finally be determined by the air density they have tendency to neglect the recognition and the application of the density altitude as a measuring scale of the air density affecting directly to the actual flight performance. Probably this tendency is caused by the complexity of applying process of the D A factor for the actual flight and their general idea of thee resultant errors which would be small amount being negligible for the safety flying. This paper is to deal with examination dy reference to the applying method of the density altitude for the flight and to the anticipated errors of flight performance in relation to the computing process of the density altitude and is emphasizing the importance of density altitude for the pilot.

9세 소아에서 나타난 비구개낭의 치험례 : CASE REPORT

이상호,모경희,박종휘,이난영,이창섭,윤정훈 大韓小兒齒科學會 2003 大韓小兒齒科學會誌 Vol.30 No.3

비구개낭은 절치관낭이라고도 불리우며 가장 흔한 비치성낭이다. 발육성으로 비구개관내에서 태생 상피잔사가 증식하여 낭변성을 일으킴으로써 발생한다. 비구개낭은 악골낭의 약 1.7-11.9%를 차지하며 남자에게서 약 3배 정도 호발한다. 연령분포는 매우 광범위하나 대개 40대에서 60대 사이에서 발견되며 10세 이전에 발견되는 경우는 매우 드물다. 비구개낭을 위한 적절한 치료는 적출이며 비구개신경에 손상을 가하지 않도록 해야 한다. 낭이 커서 치아의 생활력에 영향을 주거나 비구강누공이나 구강 상악동 누공을 형성할 우려가 있을 경우에는 조대술로 치료할 수 있다. 본 증례의 환아는 구개부의 무통성 종창을 주소로 내원하여 임상 및 방사선 검사를 실시한 결과 소아에서 매우 드물게 나타나는 비구개낭으로 방사선사진에 32×25.5mm크기를 나타내었으며, 매우 팽창되어 순측 피질골판을 관통하고 상순소대 하방과 전정부위까지 종창되어 있었다. 병소와 인접한 상악 4전치 치근은 심하게 이개되어 있었다. 낭의 크기가 매우 커서 조대술을 시행하였으며 obturator를 장착하고 있으며 향후 계속 관찰이 요한다. Nasopalatine duct cyst(NPDC) is the most common non-odontogenic cyst in the oral area and is thought to be originated from the epithelial remnants of the nasopalatine duct. Many etiologic factors have been proposed for the NPDC; trauma to the region during mastication of from ill fitting dentures, bacterial infection, and spontanious proliferation of tissue. The majority of cases are seen between the ages of 40th and 60th and it is rare in children. Surgical enucleation is the recommended treatment for NPDC, usually under general anaesthesia. A 9-year-old boy was refered to the chosun university pedodontics clinic that this child who has anterior palatal swelling is in routine check. In this case, swelling was presented at the bottom of the anterior nasal cavity as well as in the labial aspect of the upper alveolar ridge. It was so large that we treated it by marsupialization and obturator was put. This patient is on the continuous observation. We treated the child who had NPDC by marsupialization, and got the successful results such as rapid bone regeneration and the consistency of incisor vitality.

이홍모,김정욱,장기택,이상훈,한세현,김종철 大韓小兒齒科學會 2003 大韓小兒齒科學會誌 Vol.30 No.4

Rieger syndrome은 눈의 전안방 기형과 치아결손을 특징으로 하는 희귀한 유전질환으로 두 개안면 이상과 체성기형을 동반하기도 한다. Rieger syndrome은 상염색체 우선유전(autosomal dominant inheritance)되며, 발생빈도는 약 200,000분의 1이고, Paired-like homeodomain transcription factor2(PITX2)의 변이가 이 질환과 연관이 있는 것으로 보고되고 있다. 본 증례는 Rieger syndrome으로 진단 받은 4세 7개월 된 여아에 대한 것으로, 양안에 다동공증과 후태생환을 보이고, 측모두부계측에서 상악골 열성장이 나타났으며, 상악유측절치와 더불어 다수의 영구치 결손이 방사선 상에서 관찰되었다. 이 증례를 통하여 Rieger syndrome 환아의 구강 및 두 개안면의 소견을 관찰하고, 관련 문헌을 고찰하여 다소의 지견을 얻었기에 보고하는 바이다. Rieger syndrome is a rare, autosomal dominant gentic disorder characterized by malformation of the anterior chamber of the eye(goniodysgenesis) coincident with hypodontia. It may also be accompanied by a spectrum of dental, craniofacial and somatic anomalies. Mutations in paired-like homeodomain transcription factor2(PITX2) are associated with the syndrome, and its frequency in the general population has been estimated to be 1 : 200.000. In the present case, the patient, 4 year 7 month-old female, had posterior embryotoxon and polycoria. The maxilla was retrusive in cephalometric radiography. She had congenital missing on #52, #62 and some tooth germs of permanent tooth were not detected in panoramic radiography. The purpose of this paper is to report the dental and craniofacial findings and review the pertinent literature through this case.

For a complex scheduling system like time table construction, its optimal solution, if exists, is hard to obtain. In this paper, the scheduling environment is reasonably confined as where objects have their own events competing for better slots on boards, and objects have their own board slot preferences and belong to one or more classes of the society which globally constrains them. Here, two phase method is suggested, where the first phase is human-like preference dirven and the second phase is for fine tuning by considering all the factors given. Designed and implemented in our system HI-SCHED are dynamic object switching, temporal-constraint-driven intelligent backtracking, case-based revisions, object-based approach, and so on. Some satisfaction degrees are also defined to measure the usefulness of our method. In addition, look-ahead dynamic object switching is considered, and additional global constraints are introduced and processed. A simple scheme is also used to verify the usefulness of the post processing scheme.
