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.

李晶模 한국항공대학교 1991 論文集 Vol.29 No.-

경제발전과 GNP증가에 따라 여러 교통수단중 특유의 장점을 지닌 소형항공기의 수요가 증가 되면서 새로운 소형비행장 건설이 요구되고 있으며 이로 인하여 소형항공기의 소음영향도 새로운 문제로 부각되고 있는 추세이다. 본 연구는 비행기 소음이 Peak치를 나타내는 이륙시 엔진소음을 실측하여 활주로 부근의 소음분포를 분석 평가 하였으며 소형비행장 건설 및 운영에 필요한 소음영향평가 자료로서 도움이 될 것을 기대한다. With the increase of GNP the demand for small aircraft and the needs for small airfield increase considering small aircraft have peculiar merits. Owing to this, noise influences against small aircraft stand out in new problems recently. This paper attempt to take the accurate measurements of the engine noise levels of small airplane on the takeoff leg in which peak noises are produced. And the paper also analyzed and evaluated the distributions of engine noises made out on the basis of these measurements. It is to deal with materials for valuations of noise influences planning small airfield are being built or operated.

Rieger syndrome : 증례보고 A CASE REPORT

이홍모,김정욱,장기택,이상훈,한세현,김종철 大韓小兒齒科學會 2003 대한소아치과학회지 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.

Actinomycetes were isolated from soil at Kangdong area in Seoul to screen bioactive metabolites. One of strains having antibacterial activity was selected and characterized. The isolated strain was identified as Streptomyces sp. on the basis of its cultural, morphological and physiological properties. This strain produced antibacterial substances in culture broth after 7days cultivation, and its productivity continued to increase for 14 days. The metabolites exhibited potent antibacterial activities to various bacterial strains including multidrug-resistant strain of Staphylococcus aureus.

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.

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).
