The purpose of this study was to obtain the basic information for the improvement of dental environment by investigating the presence of methicillin- or vancomycin-resistant Staphylococcus aureus (MRSA or VRSA) isolated from dental health care workers (DHCWs) and environment of the Chosun University Dental Hospital (CUDH) and a private dental clinic (control group). Staphylococcus aureus (S. aureus) was isolated from anterior nares of 42 DHCWS and 38 sites, unit chairss, x-ray devices, computers, etc., at 10 departments of the CUDH and 20 DHCWs and 11 sites at the private dental clinic. S. aureus was isolated on mannitol salt agar plate and confirmed by PCR with S. aureus species-specific primer. Antimicrobial susceptibility test of clinical isolates of S. aureus against several antibiotics including methicillin (oxacillin) was performed by investigating minimum inhibitory concentration (MIC) using broth microdilution assay. In addition, PCR was performed to detect the methicillin- or vancomycin-resistant gene. The data showed that one strain of S. aureus was isolated from DHCWs of the CUDH and three strains of S. aureus was isolated from 3 samples of the private dental clinic, respectively. All of the isolates from the CUDH and the private dental clinic had resistance to penicillin G, amoxicillin and vancomycin and susceptibility to oxacillin and ciprofloxacin. The S. aureus strains were already obtained the resistance to penicillin G and amoxicillin. These results suggest that two dental clinics were under relatively safe environment.

In this study, the calculation of the effective spatial dose distribution of the diagnostic imaging laboratory of K university was performed by the Monte Carlo simulation. The radiation generator has a maximum tube voltage of 150 kVp and a maximum current of 700 mA. Using the results, we compared the spatial effective dose distributions of diagnostic imaging laboratory when the shielding door was closed and opened. In conclusion, it was found that the effective dose in the operating room of the diagnostic imaging laboratory does not exceed the annual dose limit (6 mSv/y) of the student (occasional visitor) even when the door is opened. However, since the effective dose when the door is open is about 16 times higher in front of the lead glass window and about 3,000 times higher in front of the doorway than the case when the door is closed, closing the shielding door at the time of the practical exercising reduces unnecessary radiation exposure by great extent.

Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from "A Study for Standard Triage Design and Construction Document" but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.

Electrocardiogram and phonocardiogram acquired from ECG and stethoscope by a non-invasive method are bio-signals which laue been a great role in patients diagnosis and used extensively by doctors. And these are mainly used at the examination room or first-and room of hospital. When the patients are located at some places far away from hospital like a car, an airplane and a vessel under way, there are some difficulties in confirming their cardiac sound Especially the patient of ocean going vessel might not have a medical treatment from the professional doctor at times. In this paper, we developed the digital ECG and stethoscope system based on personal computer which can easily measure the patient's cardiac sound and ECG signal, and this might shorten the appearance of the remote maritime telemedicine.

The word 'aesthetic', one of three functions of the teeth - mastication, pronunciation, and aesthetic - does not simply mean beauty. Aesthetic missing harmony cannot be called aesthetic. It is true aesthetic when the harmony with surrounding teeth and environment such as lips, midline, and facial form is achieved. In order to produce a harmonious prosthesis, sufficient information must be passed on to a technician, and also the technician should request necessary information to the dental office. Good food cannot be made without fresh ingredients. Although fresh ingredients are supplied, delicious food is also not possible without a chef's cooking skills. The first-class dish is made only under the circumstances that a skilled chef can do his best with fresh ingredients. In this study, the teamwork to be shared between dental practitioners and technicians for harmonious aesthetic prosthesis is discussed.

Recently, digital technology and computer-aided design/computer-aided manufacturing (CAD/CAM) environment have changed the clinician treatment method in the fabrication of dentures. The denture manufacturing method with CAD/CAM technology simplifies the treatment and laboratory process to reduce the occurrence of errors and provides clinical efficiency and convenience. In this case, complete dentures were fabricated using stereolithography (SLA)-based 3D printing in patient with mandibular deviation. Recording base were produced in a digital model obtained with an intraoral scanner, and after recording a jaw relation in the occlusal rim, a definitive impression was obtained with polyvinyl siloxane impression material. In addition, facial scan data with occlusal rim was obtained so that it can be used as a reference in determination of the occlusal plane and in arrangement of artificial teeth during laboratory work. Artificial teeth were arranged through a CAD program, and a gingival festooning was performed. The definitive dentures were printed by SLA-based 3D printer using a Food and Drug Administration (FDA)-approved liquid photocurable resin. The denture showed adequate retention, support and stability, and results were satisfied functionally and aesthetically.

우리 주위에는 '어떤 음식이나 약을 먹으면 ○○에 좋다'는 것이 너무나 많습니다. 한 때는 토마토가 암을 예방한다고 해서 가격이 올라가기도 했었고, 스쿠알렌, 죽염, 알로에, 오가피, 동충하초 등 여러 가지 건강식품이 등장했다 이내 시들해지곤 합니다. 하지만 이런 건강기능식품을 제대로 알고 먹지 않으면 각 체질에 따라 좋은 반응과 나쁜 반응으로 작용할 수 있습니다. 대부분의 건강한 사람들은 골고루 음식을 먹으면 좋습니다. 그러나 정말 골고루 먹는 사람이 얼마나 될까요? 거의 없다고 해도 지나친 말은 아닙니다. 오히려 대부분의 사람들은 자신이 평소에 먹어왔고, 가족들이 자주 먹는 친숙한 음식만 먹고 있습니다. 60대 중반의 목소리가 우렁찬 할아버지가 진료실에 왔습니다. 그 분은 20대 때 베트남에 파병되었고, 약 3년간 미군들과 함께 생활하면서 매운 음식을 먹지 않게 되었는데 그 이후 위장병이 사라 졌으며, 지금까지도 김치를 물에 씻어서 먹고 있다고 했습니다. 이분의 체질은 소양인이었고, 매운 음식을 조심한 것이 만성 위장병을 치료하는데 결정적인 역할을 했다고 판단됩니다.

구강질병의 합리적인 관리는 질병의 원인규명을 바탕으로 예방과 치료가 이루어 져야 한다. 구강의 발생학적, 생리학적인 복합성 때문에, 구강질병에 대한 정확한 이해가 어려우므로 치과진료실에서의 진료행위는 상당한 제한된 것이었고 불완전한 것이었다. 치아의 지지경조직, 연조직, 기타 구강에 영향을 주는 제반질병의 합리적인 관리가 구강내과학적으로 우선되야 할 것이다. 치과의사는 백혈구나 적혈구에 이상이 있는 환자는 치료하는 경우에 주의하여야 할 점이 많으므로 환자의 병력, 임상검사 및 예비검사등에 의하여 이러한 질병을 발견할 수 있어야 한다. 이러한 환자에서는 비정상 출혈, 치유지연, 감염 혹은 점막 궤양이 나타나기 쉽다. 더구나 이들 중 어떤 질환은 치명적으로 이런 환자를 찾아내어 치과처치를 하기전에 내과의사에 보내어 진단, 치료를 받게 해야 한다. 환자자신이 질환에 대해 알고 있고 내과적 처치를 받고 있는 경우라도 의사와 협의가 없이는 어떠한 치과적 처치라도 피하도록 하는 것이 좋겠다. 이에 이러한 혈액질환들의 원인과 증상, 치료법등을 간단히 소개하여 수차에 걸쳐 연재하도록 하겠다. 여기에 연재된 내용들은 어떤부분에서는 너무 자세하게 기술된 내용도 없지 않으나 조금이나마 환자 치료에 도움이 되었으면 하는 바램이다.

We dentists perform many of routine dental procedures and must deal with much of the population's dental anxiety and fear. Dentists have used many non-pharmacological modalities initially to overcome anxiety and fear, including distraction, empathy, desensitization, and so on. However, certain patients need pharmacological backup of anxiety and fear to conquer dental treatment. This article presents four cases to introduce the methods from nitrous oxide and oxygen inhalation to general anesthesia for difficult adult dental phobic patients to deal with.
