Purpose: Bisphosphonates are drugs used to suppress osteoclastic activity and to treat osteoporosis, Paget's disease of bone and bone metastasis. The purpose of this report is to review the literatures on bisphosphonates use that could affect bone healing and cause osteonecrosis of the jaws. Materials and methods: Medline research was carried out to find relevant articles on bisphosphonates and osteonecrosis of the jaw. Results: Oral administration of bisphosphonates is reported to decrease the risk of adverse bone outcomes. On the contrary, IV bisphosphonates is known to significantly increase the risk. Prevention of the osteonecrosis of the jaw is primary concern before usage. If the adverse bone reaction takes place, proper management and treatments are required to alleviate pain of patients and prevent further progression of necrosis. Conclusion: Case reports of bisphosphonates induced osteonecrosis of the jaw are increasing. Dentists and physicians should be aware of the higher frequency of osteonecrosis of the jaw in patients receiving IV bisphosphonates and be prepared to prevent and cope with adverse bone reaction.

Purpose: Cemental tear is an uncommon form of root fracture that can lead to rapid localized attachment loss. When it is exposed in the periodontal pocket, it should be removed to prevent accumulation of dental plaque and calculus. Material and Methods: 2 patients were diagnosed as a cemental tear and they were treated with conventional flap operation and subgingival curettage. Additional treatments such as bone graft or guided tissue regeneration were not performed. Result: Symptoms subsided after the treatment. Periodontal pocket has been reduced but no gain of clinical attachment was observed. Remnant of cemental fragment remained after curettage. However, periodontal pocket was stably maintained and there was no recurrence. Conclusion: Periodontal attachment loss associated with cemental tear can be successfully treated with conventional periodontal surgical and nonsurgical procedures.

초등학교에서 한글교육은 국가수준의 기본적이고 책임 있는 교육으로 논의되며 초등학교 저학년에서는 당연히 해득을 해야 한다는 당위성과 교사의 책무성을 가진다. 이전 개정교육과정과 달리 2015 개정교육과정에서는 한글교육이 강화되어 27시간의 한글교육이 62시간으로 확대 운영되고 있다. 이러한 개정교육과정의 움직임에 발맞추어 다양한 한글교육의 시도가 이루어지고 있지만 그에 따른 인성교육의 필요성 또한 중요시 되는 것이 사실이다. 이에 초등학교 1,2학년 한글교육의 실태를 분석하여 그 방안을 알아보고 인성교육의 필요성 및 활성화 방안과 연계하여 알아보았다. 이러한 연구를 위해 교과서 분석 및 설문조사, 전문가 협의회를 통해 한글교육의 실태 및 인성교육 활성화 방안에 대해 논의하였으며 학교현장에서 한글 책임 교육이 이루어지기 위해 한글 관련 차시 증가 및 관련 자료보완, 학습 보조 자료의 활용 방안 탐색을 활용한 한글책임교육의 당위성과 필요성에 대해 말하였다. 그러나 한글교육의 증대에 따른 인성교육의 활성화 방안에 대한 필요성 및 다양한 해결 방안에 대한 제시는 아직까지 미흡한 것이 사실이다. 책임 있는 한글교육과 그에 따른 올바른 인성교육은 초등학교에서의 전인적인 인격 형성은 물론 미래 역량 강화에 가장 기본적으로 요구된다. 따라서 다양한 한글교육의 운영방안과 연계한 인성교육 프로그램의 적용이 더욱 요구된다. In elementary school, Korean language education is discussed in basic and responsible education at the national level, and in the lower grades of elementary school, it has the right to understand and the responsibility of the teacher. Unlike the previous revision curriculum, Korean language education is strengthened in the 2015 revised curriculum, and 27 hours of Korean language education is expanded to 62 hours. In response to the revised curriculum, various Korean language education attempts have been made, but the necessity of personality education is also important. Therefore, we analyzed the actual situation of Korean language education in the first and second grade of elementary school, and tried to find out the plan and to link it with necessity and activation plan of personality education. For this study, we discussed about the actual condition of Korean language education and how to activate character education through textbook analysis, questionnaire, and expert council. In order to make Korean language accountable in school, We talked about the necessity and necessity of Korean responsibility education using exploration plan. However, the necessity of activating personality education due to the increase of Korean language education and various solutions are still not enough. Responsible Korean language education and correct personality education are basically required to strengthen the future competence as well as the formation of the whole personality in elementary school. Therefore, the application of the character education program in connection with the management plan of various Korean language education is further required.

Cigarette smoking is a significant risk factor for periodontaldiseases and implant treatments. Smoking control is regarded as a key to the success of dental treatments as well as the well-being of the patients. The aim of this study was to reviewthe effects of smoking on periodontal health, and the results of periodontal therapy and implant treatments. Also, in vitro, microbiological, immunological and epidemiological relationships were studied. In vitro studies show that smoking interferes with normal healing process and increased tissue destruction. There is still controversy on the population of microbes of smokers. Smokers showed significantly less gingival inflammation and bleeding on probing compared with non-smokers. After periodontal treatments, a compromised clinical outcome was noted for smokers in terms of pocket depth reduction and gain in attachment levels. In conclusion, data from in vitro, epidemiological, cross-sectional and case?control studiesstrongly suggest that quitting smoking is beneficial to patients before periodontal and implant treatments.

Exogenous lipoid pneumonia (ELP) is a chronic inflammatory reaction of the lungs resulting from the aspiration of vegetable, animal or mineral oils. Squalene, is a derivative of shark liver oil that is taken as a traditional remedy in some Asian countries, and is used widely also in cosmetics. Similar to the symptoms in most cases of oil aspiration, the symptoms of squalene-induced lipoid pneumonia are either absent or nonspecific. Hence, the disease is generally detected incidentally. Although many cases with predisposing factors have been reported, ELP with achalasia is quite rare. We report a 47-year old woman with achalasia who developed ELP after ingesting squalene. The patient was treated successfully by supportive care and surgical treatment of the achalasia. (Tuberc Respir Dis 2008;65:421-425)

박정철(Park, Jung-Chul),강현석(Kang, Hyeon-Suk) 학습자중심교과교육학회 2013 학습자중심교과교육연구 Vol.13 No.5

In schooling the most professional and the basic thing is knowledge about curriculum content. PCK is also true of the music curriculum in fostering teacher s professionality. In teaching key concept in the music, teacher s professionality with the right knowledge is important for relating experience to student. However, in the vein of existing class of music, students interest and attention does not lead to transfer of knowledge to the teacher s unilateral conveyance. Teaching a subject is interpreted by way of understanding of curriculum context which teacher s narrative activates. Pedagogical content knowledge is embedded in narrative knowing. Narrative is conceptualized as storytelling, meaning-making, and communication. In this research, elementary music and narrative in the PCK model, utilizing a variety of teacher s experience and knowledge with a narrative, is powerful tool for enhancing student s right understanding. Narrative and the relationship between music and PCK learning model as a basis for professional development of teachers provide students with musical understanding. 오늘날 학교 현장에서 교사들에게 요구되는 가장 전문적이고도 기본적인 지식은 교과 내용과 그 내용을 제대로 가르치는 데에 관련된 지식(PCK)이라는 점에는 이견이 없다. 음악 교과의 PCK의 경우도 마찬가지이다. 음악 수업에서 특정 개념을 지도할 때 그 개념을 학생들이 실질적으로 내면화하도록 제대로 학생들에게 전달하는 것(내용의 변환)이 중요하다. 2000년대 이후 학생들에게 제대로 내용을 가르치기 위한 수단으로 내러티브에 대한 관심이 증가하고 있다. 하지만 이에 대한 심층적인 연구는 부족한 실정이다. 기존 음악과 수업에서 학생들의 흥미나 관심을 유도하지 못하고 단순히 교사의 일방적 지식 전달에 그치는 경우가 종종 있다. 음악적 지식의 내면화가 제대로 이루어지지 못하고 있는 문제를 안고 있다. 이에 본 연구에서는 초등학교 음악과에서 내러티브를 활용한 PCK 모형을 탐색해봄으로써 교사의 다양한 경험 및 지식을 내러티브적으로 구성하여 올바른 이해를 통하여 학생들을 교육 목표에 도달하는데 도움이 되는 방안을 발견하는 데 목적을 두고 있다. 이를 위하여 내러티브와 음악과 PCK의 관계를 살펴보고 관련 모형을 탐색해본다. 이를 통하여 음악교사의 전문성 신장을 위한 근거 를 설정하고 음악교육에서 학생들이 보다 흥미와 관심을 가지고 수업에 참여하여 다양한 경험을 통한 이해를 증진할 수 있는 방안을 마련해보고자 한다.

Purpose: Infection with HIV-1 virus has become a critical worldwide public health problem. The oral complications of HIV infection with its progression of Impairment of the host response to combat infection present unique challenges to the periodontists. Material and Methods : Medline research was carried out to find relationship of the progression of HIV infection to the occurrence of oral lesions including the HIV-related periodontal diseases. Results; The linear gingival erythema, necrotizing ulcerative periodontitis, necrotizing ulcerative gingivitis and oral candidiasis are common lesions in HIV-infected individuals. The linear gingival erythema and necrotizing ulcerative periodontitis lesions in HIV-infected subjects were found to have a similar microbiological profile. There are several general considerations in the periodontal management of the HIV-infected patient with or without periodontal disease. The altered immunity and host response in patients with HIV infection may also affect the incidence and severity of other common forms of periodontal disease not associated with HIV infection. Conclusion: Periodontal diseases in HIV-infected individuals present unique challenges in diagnosis, monitoring, treatment and maintenance. Therefore exact HIV staging, geographic location, antiviral and antimicrobial therapies and oral habits should be taken into consideration when treating HIV-infected patients.
