조종만,Jo, Jong-Man 대한심미치과학회 2004 Journal of the Korean Academy of Esthetic Dentistr Vol.13 No.1

For the prosthodontic results which are compatible with esthetics to be fulfilled, the first prerequisite would be periodontal intervention and stability, the second one may be functional competency and the ultimate goal should be ascribed to esthetic considerations. Other words, esthetic dentistry is a whole entity which encompasses the biological stability of the periodontium, physical accuracy of the prosthodontic structure and finally, the beauty which can be found in natural dentition. It also implies the harmonized lip line which reveals the well-balanced tooth morphology and health gum profiles (Red-White Esthetics). Largely, there lie some differences in the input system of the 3-dimentional data from the prepared abutments between respective computer-assisted systems available now. But the manufacturing systems (CAM) are very similar between them, to say, comprise numeric control systems with whole 3-dimensional milling units according to the restorations to be made. Now the author is going to present CAD/CAM Zirconia All Ceramic Restoration on the topics for the Red-White Esthetics, periodontal control and maintenance, treatment for the discolored teeth, post & core build-up works for the devitalized teeth, characteristics of the Zirconium oxide All Ceramics, fabrication procedures, clinical considerations and its application to diverse clinical situations.

Insulin-like Growth Factor가 치주인대세포의 증식에 미치는 효과에 관한 연구

조종만,김형찬,이종흔 대한구강생물학회 1992 International Journal of Oral Biology Vol.16 No.2

Insulin-like Growth Factor(IGF-I) has the potent chemotactic and proliferative effect on preosteoblasts and hematocytes. There were many researches on bone cells, but now there are insufficient data of the effect of IGF-I on the periodontal ligament(PDL) cells. The purpose of this study is to evaluate the effects of IGF-I on the PDL cells. Human PDL cells were prepared from the first premolar tooth extracted for the orthodontic treatment and were cultured in DMEM/10% FBS at a CO_2 incubator(37℃). The concentrations of IGF-I were as follows: 3ng/㎖, 6ng/㎖, 12ng/㎖, 25ng/㎖, 50ng/㎖, 100ng/㎖ and 150ng/㎖. In the IGF-I group, cell numbers were estimated by counting cells under the microscope at 2 days after. Protein determination was made by the method of Lowry et al. The observed results were as follows: 1. The IGF-I group showed the concentration-dependent increase of cell numbers at 2 days after. IGF-I stimulated significantly PDL mitosis at all concentrations. 2. The maximum effect of PDL proliferation was observed at the concentration of 25ng/㎖ IGF-I. Its effect was about twofold than that of the control group. At that concentration, cell numbers were(12.28±1.10)×10^4cell/㎖ 3. Protein contents of PDL cells was increased in all experimental groups and the degree of increase in protein contents was highest at concentration of 25ng/㎖ IGF-I

재난관리기관간 협력체계구축을 위한 영역별 상대적 중요도 분석

우리나라의 경우 1990년대 중반이후 재난관리에 국가적 차원에서 법과 제도를 제ㆍ개정하면서 지속적인 노력을 기울임에도 불구하고, 유사한 사건사고가 발생하면 재난관리에 실패를 하고 또 다시 문제점과 한계를 드러내고 있다. 이에 본 연구는 재난관리의 효과성 향상을 위해 다양한 재난관리 참여기관들이 협력체계를 구축하기 위해서는 무엇이 우선시 되어야 하는가를 전문가를 대상으로 하여 실증연구를 실시하고자 하였다. 결과적으로, 재난관리 전문가(중앙ㆍ지방정부, 학계/연구소, 군, 경찰, 소방)를 대상으로 실시한 참여기관의 협력요인간 상대적 중요도 및 우선순위를 분석한 결과, 조직화→의사소통 및 의사결정→조정 메커니즘→계획→협력 조직문화의 순으로 중요도가 나타났으며, 또한 재난관리 참여기관 협력체계 구축을 위한 요인간 중요도 및 우선순위에 대한 복합가중치를 보면, 지식 및 정보 공유→ 협력 기구 마련→통합 지휘체계 마련→정기회의 및 결정→협력 운영절차 마련순으로 중요도가 측정되었다. 이는 재난관리 참여기관간 협력체계를 구축하기 위하여 협력 기구 및 운영 절차 등 관련규정과 제도 등을 정비하고 참여기관 간 재난정보 등을 공유하는 활동이 중요하다. 또한 초기 재난발생시 효과적인 대응을 위하여 통합지휘체계를 마련함으로서 일사불란한 재난관리 활동이 요구된다. This study examines the relative importance and priority of the policy area and policy variables in the field of the Cooperative factors of Agencies in Disaster Management by using analytic hierarchy process(AHP). According to the results of surveying disaster management specialists (central-local governments, universities/research institutes, army, police, fire service) on the relative importance and priority of factors related to cooperation among participating institutions, importance was high in order of organization → communication and decision making→ coordination mechanism → planning → cooperative organizational culture. In addition, the combined weight of the importance and priority of factors for building a cooperation system among institutions participating in disaster management was high in order of knowledge and information sharing→ establishment of a cooperation organization → establishment of an integrated command system → regular meetings and decision making → establishment of cooperative operation procedures. That is, in order to build a cooperation system among institutions participating in disaster management, it is important to improve relevant laws and systems including the cooperation organization and operation procedures and to share information on disasters among the participating institutions. Furthermore, it is required to execute well-organized disaster management activities by establishing an integrated command system for early and effective coping with disasters.

This research focused on the development of wireless telemetry system that can monitor heart rates of multiple rehabilitation patients in real time without constraint. The whole system consists of the multiple patient's side devices (PSDs) and one central monitoring system (CMS). The PSD consists of a microphone, amplifier, filter, microcontroller, and RF (Radio Frequency) modem. In addition, the PSD was designed to be wearable and low power consumption. The CMS consists of an RF modem and general PC and it was designed to monitor heart rates from multiple patients simultaneously. The system warns an alarm signal when a patient's heart rate exceeds the pre-set range for each patient. This system can be useful to monitor the heart rate of exercising rehabilitation patients and control the patients condition and the exercising level.

흑질(Substantia nigra)이 하악운동과 저작근 활성도에 미치는 영향

조종만,박경표,김중수 대한구강생물학회 1986 International Journal of Oral Biology Vol.10 No.2

Various patterns of the mandibular movement were induced by repetitive electrical stimulation of the cerebral cortex and subcortical structures in the rabbit. Substantia nigra(SN) was important on motor function related to the execution of jaw movements, but the role of SN has been controversial. This experiment was performed to clarify the modulatory effect of SN on mastication. The experimental animals were anesthetized with urethane and tracheal cannula was inserted. Wire electrodes were inserted into both masseter muscles and anterior belly of digastric muscles for recording of EMGs. The head was placed to stereotaxic apparatus and bipolar electrode was fixed to the right cortical jaw motor area and SN, and threshold intensity was determined. In some experiments, SN was destructed by lesion generator or the brain was decerbrated. The jaw movement was evoked by electrical stimulation of cortex, SN or both simultaneously and recorded by using photo - sensitive detector. All patterns of jaw movements and EMGs activity were recorded with maignetic tape recorder and compared before and after destruction of the SN or decerebration. The cortical stimulation produced prominent vertical and lateral movement. But the cortically-induced mastication was decreased by destruction of SN. The SN stimulation in normal rabbit mainly produced vertical movement. In decerebrated animal, however, vertical and lateral movements evoked by SN stimulation were markedly changed and masseter and digastric EMGs were reduced, especially, masseter EMGS showed tonic activity. Simultaneous stimulation of cerebral cortex and SN with subthreshold intensity could induce masticatory movements. At simultaneous stimulation of cerebral cortex and SN with subthreshold and theshold intensity, the pattern of jaw movenment depended upon higher intensity.
