노인에서 턱관절 장애와 골밀도의 관련성에 관한 예비 연구
김문종 대한노년치의학회 2022 대한노년치의학회지 Vol.18 No.2
Purpose: The aim of this study is to investigate and compare bone mineral density in patients with temporomandibular disorders (TMD) and healthy controls to confirm the relationship between TMD and osteoporosis. Methods: 107 TMD patients and 50 healthy controls were included in this study. Among the TMD patients, 50 were diagnosed with osteoarthritis in at least one joint. Mandibular cortical width (MCW) and panoramic mandibular index (PMI) were calculated in all participants using panoramic radiographs to evaluate bone mineral density. Results: The mean age was not significantly different between the TMD patients and controls. There were significantly more female subjects in the TMD group than in the controls. The TMD patients with osteoarthritis displayed lower values of MCW and PMI than those without osteoarthritis. However, only the difference in the value of MCW showed statistical significance. Conclusion: The patients with TMD have lower bone mineral density than the healthy controls. Additionally, compared to the TMD patients without osteoarthritis, the TMD patients with osteoarthritis have reduced bone mineral density. These findings suggested that osteoporosis may be related to the pathophysiology of TMD and osteoarthritis.

중학교 기술·가정과의 STEM 통합교육을 위한 녹색 자동차 만들기 수업 자료 개발
김문종,우상호,김진수 한국기술교육학회 2011 한국기술교육학회지 Vol.11 No.2
The Purpose of this research was to develop the instruction material of making moving objects that can be used for STEM education at 'an electronic-machine technology' unit in 2007 revised course of technology·home economics subject. The process of study was developed by using ADDIE(analysis, design, development, implementation, and evaluation) model. The developed material was evaluated by expert group on the basis of evaluation criteria. The study was tried to figure out the effect when the material is applied to learners. The findings of the study can summarize as following. First, the developed material for making green car model for STEM education has been organized to cultivate the technical ability of understanding the fundamentals of moving objects and making it directly. Second, a green car model was made directly while the study guidance plan, study activity sheet and PowerPoint materials related to this was validated and produced by applying to the actual class to be directly used in the teaching-learning process. Third, as a result of applying to student lessons, students understood the fundamentals of machine, electricity and electronics more easily in the teaching-learning process, had a great deal of interest in the process of making a green car model which is a moving objects and was analyzed as having high validity as a result of validity assessment by a group of specialists. 이 연구의 목적은 STEM 교육을 위해 2007년 개정 교육과정에서 기술ㆍ가정과의 ‘전자 기계 기술’ 단원에서 적용될 녹색 자동차 모형 만들기 수업 자료를 개발하는데 있다. 이 연구를 수행하기 위해 ADDIE 모형에 의한 수업자료 개발 과정을 거쳤고, 개발된 수업자료는 전문가 집단에 의한 평가와 실제 수업에 적용하여 수정․보완하였다. 이 연구의 결과는 다음과 같이 요약할 수 있다. 첫째, 기술․가정과의 ‘전자 기계 기술’ 단원에서 ‘운동 물체 만들기’ 교수-학습을 위해 개발된 STEM 통합교육용 녹색 자동차 모형 만들기 수업자료는 학생들의 만들기 능력의 배양을 통해 운동 장치의 원리를 이해할 수 있도록 하였다. 둘째, 개발된 수업 자료는 솔라셀에 의한 친환경 에너지를 이용하는 녹색 자동차 모형과 이를 실제 교수-학습하게 되는 수업 지도안, 학습 활동지, 파워포인트 자료 등을 ADDIE 모형의 개발 단계에 의해 체계적으로 개발 하였다. 셋째, 개발된 자료는 수업에 적용하여 교수-학습 과정에서 기계, 전기, 전자의 원리를 이해하는 만족도를 확인하였다. 학생들은 녹색 자동차 모형을 만드는 과정을 통해 수업에 대한 동기부여와 이해도를 높일 수 있는 것으로 조사되었다. 전문가 집단에 의한 타당성 평가 결과가 5점 만점에 4.413, 학생들의 만족도가 3.442로 높게 나타났다.

후기 발현 남성 성선기능저하증에 대한 2006 대한남성갱년기학회 호르몬치료 권고안
김문종,이유미,서주태,양대열,문두건,박남철,김제종 대한남성과학회 2008 The World Journal of Men's Health Vol.26 No.1
Androgen deficiency in the aging male has become a topic of increasing interest and debate throughout the world. The evidence from results showing that testosterone decrease progressively with age and that a significant percentage of men over the age 60 years have serum testosterone levels that are below the lower limits of young adults(age 20∼30) men suggest that older hypogonadal men will benefit from testosterone replacement therapy. Long term data on the effects of testosterone replacement therapy in the older population, however, are limited and specific risk data on the prostate and cardiovascular systems are needed. Key questions of functional benefits that may retard frailty of the elderly are not yet available. The recommendations described below were based on document suggested by the International Society of Andrology(ISA), the International Society for the Study of the Aging Male(ISSAM) and the European Association of Urology(EAU) in 2005. The academic committee of the Korean Society for the Aging Male Research(KOSAR) suggested these recommendations to provide the appropriate information about investigation, treatment and monitoring for late-onset hypogonadism in aging Korean men following an annual meeting in October 2006.

Treatment Outcomes of Venlafaxine and Duloxetine in Refractory Burning Mouth Syndrome Patients
김문종,고홍섭 대한안면통증∙구강내과학회 2019 Journal of Oral Medicine and Pain Vol.44 No.3
Purpose: Venlafaxine and duloxetine have been shown to be effective in the treatment ofneuropathic pain disorders. However, knowledge about the efficacy of venlafaxine and duloxetineon burning mouth syndrome (BMS) is still insufficient. The purpose of this studywas to investigate the efficacy of venlafaxine and duloxetine on refractory BMS patients. Methods: Twelve refractory BMS patients who were prescribed venlafaxine or duloxetinewere included in this study. These patients did not respond to previous administration ofclonazepam, alpha-lipoic acid, gabapentin, and nortriptyline. All participants were the primarytype of BMS patients who had no local and systemic factors related to the oral burningsensation. The intensities of oral symptoms following venlafaxine or duloxetine administrationwere compared with those before administration and at baseline. Results: Venlafaxine and duloxetine were prescribed to four and nine patients, respectively. One patient was prescribed both medications in turn. Among them, only two patientsshowed improvement of oral symptoms without side effects. In the other ten patients,symptoms failed to improve. Six of them reported that the drug was ineffective, and fourof them stopped taking the medications on their own due to intolerable side effects, such asinsomnia, constipation, drowsiness, dizziness, and xerostomia. Conclusions: Venlafaxine and duloxetine may only relieve oral symptoms in a minority ofrefractory BMS patients. Further large-scale studies are needed to determine the potentialclinical factors that could predict the efficacy of venlafaxine and duloxetine.
