Background: Extrusion of debris is a major factor that results in postoperative pain during root canal treatment with various instruments and instrumentation techniques. Therefore, instrumentation techniques that extrude minimal debris into the periapical area while reducing pain are desirable. This study aimed to compare the incidence of postoperative pain and intake of analgesic medication (frequency and quantity) after endodontic treatment of mandibular posterior teeth using two single files and full-sequence continuous rotary systems with different kinematic motions. Methods: Thirty-five of 105 patients were assigned equally to three groups according to the instrumentation system used: ProTaper Next (PN) X2, 25/06 (Dentsply, Maillefer, Ballaigues, Switzerland), One Shape (OS), #0.25/06 (Micro Mega, Besancon, France), and Wave One Gold (WG), Red - #0.25, 0.07 (Dentsply, Maillefer, Ballaigues, Switzerland). Five specialists were included in this study design; each professional prepared 21 teeth, and randomly selected 7 per instrument system. The VAS sheet ranging from 0 to 10 was used to record the initial and postoperative pains at 24, 48, and 72 h, and 7^th day after single visit endodontic treatment in mandibular premolars and molars with a diagnosis of asymptomatic irreversible pulpitis with or without apical periodontitis. Postoperatively, an analgesic, ibuprofen 400 mg was administered for intolerable pain at a dose of 1 tablet for 6 h. The patients were asked over the telephone regarding postoperative pain at intervals of 24, 48, and 72 h, and 7^th day using a visual analogue scale. Result: There were no statistically significant differences among the PN, OS, and WG systems (P > 0.05) with regard to the incidence of postoperative pain at any of the four time points assessed. Conclusion: The intensity of postoperative pain, frequency, and analgesic intake were similar across all three types of instrument systems; however, the reciprocating single file (WG) was associated with less postoperative pain than the full sequence continuous rotary file.

본 연구에서는 기존에 임상에서 염색제를 사용한 치면세균막검사와 periodental probe를 사용한 치은지수 평가방법대신 새로운 디지털 형광 장비인 QLF-D를 이용한 검사법의 활용 가능성을 확인하고자 하였다. 염색제를 이용하여 치면세균막지수를 산출하여 연구 대상자를 위험군별로 구분하여 일반적 특성을 확인하였고, 분석 소프트웨어를 이용하여 산출되는 QLF-D score와 전체 및 전치부 치면세균막지수, 치은지수의 상관성을 확인하였다. 정상치은과 치은염에 따른 QLF-D score를 비교하였고, 각 QLF-D score에 따른 치면세균막지수와 치은지수의 평균값을 비교하여 다음과 같은 결론을 내렸다. 연구대상자의 염색제를 이용한 평균 치면세균막지수는 $42.28{\pm}17.90$이었고, 6개의 선택치아의 치은지수는 $1.05{\pm}20.38$로 나타났으며, QLF-D score는 $1.26{\pm}1.50$이었다. 상하악전치부 QLF-D score와 치면세균막염색을 이용하여 평가한 전치부 치면세균막지수의 상관 분석 결과, 유의한 양의 상관관계를 확인하였다(r=0.638, p<0.001). 또한 상하악 전치부 QLF-D score와 periodontal probe를 이용한 치은지수와의 관계를 분석한 결과에서도 두 가지 평가 지표 간에 유의한 양의 상관관계를 보였다(r=0.562, p<0.001). 치면세균막지수와 치은지수에 따른 QLF-D score의 차이를 저위험군과 고위험군으로 분류하여 비교한 결과, 치면세균막지수(p<0.0001)와 치은지수(p=0.007) 모두 저위험군에 비해 고위험군 집단에서 QLF-D score가 통계적으로 유의하게 높았다. QLF-D score에 따른 치면세균막지수 및 치은지수 평균값을 비교한 결과, QLF-D score가 증가할수록 두 가지 지수 모두 통계적으로 유의하게 증가하는 양상을 보였다(p<0.0001). 이와 같은 결과를 통해, QLF-D로 치면세균막을 평가함으로써 치은상태를 모니터링 하는 것이 가능함을 확인하였다. 이를 통해 임상 현장에서 QLF-D를 활용한다면, 비교적 간편하게 구강 이미지를 획득하고 구강 상태를 점수화하여 제시함으로써 술자의 진단 절차가 간편해지고 환자와의 의사소통이 원활해질 수 있을 것으로 사료된다.

Purpose: The purpose of this study was to identify international students' use of university health centers by individual characteristics and seasons. Methods: This was a retrospective descriptive study using data obtained from the electronic record system of one university health center. The study participants were international undergraduate students who registered for any of two semesters between March 1, 2014 and February 28, 2015 and visited the university health center during their registration period. Results: The most common reasons for visits were problems of head, eye, nose and throat systems, followed by respiratory system. Their visits mostly occurred in the fall and spring. The most frequently used services were distribution of oral medication followed by wound treatment. The number of visits per individual was statistically different by gender (u=-3.307, p=.001), but not by their major (${\chi}^2$=.543, p=0.762) or nationality (${\chi}^2$=5.518, p=.271). Conclusion: Further study is necessary to better define health needs and related factors for this unique population. The electronic record system provides great opportunities in development and application of need based health services for international students and for research in this area.

Purpose: This study was to identify the types and characteristics of health problems of middle school students in Gangwondo. Methods: The subjects of the study were 11 middle schools from 47 schools with nurse teachers in Gangwondo. The anecdotal records of the school health clinics were collected from March to December in 1998 with the agreement of nurse teachers of the schools. Results: 71.0% of the middle students visited the school health care clinics once or more than once. The mean frequency of health problems was 2.03 times per one year. The rate of health problems did not show any statistical differences by sex, school location, age, the day of the week and weather. However, there were statistical differences of the rate by month. The highest rate was showed in September, followed by June and April (F=2.52, p=0.01). Health problems were classified into 11 types. Gastrointestinal illness showed the largest proportion (60.6%). The oral illness showed statistical differences among the location of school, between municipal and rural area (t=-2.97, p=0.016). There were 411 types of signs and symptoms recorded. Among them, headache was showed the highest proportion with 2,122 cases (11.2%). Conclusion : The incidence rate of health problems was higher than that of earlier studies. It showed that the incidence rates and the types of diseasps in middle school students were different by school locations, characteristics of students, and months. To improve the qualities of primary cares in school health services, the reformed and unified anecdotal record system and the standardized guidelines for primary care are necessary.

성공회대 노동사연구소는 2001년 당시 전태일노동자료실의 소장 기록물이 성공회대에 기탁되는 것을 계기로 출범하게 되었다. 이후 문헌자료를 바탕으로 대규모 구술조사 연구사업을 진행하면서 노동아카이브와 노동연구의 바람직한 관계를 형성해 왔다. 하지만 노동기록이 축적되어감에 따라 새롭게 해결되어야 하는 문제들이 발생했다. 가장 중요한 것은 노동기록의 생산자(구술증언자)들의 불만족이었다. 기록의 이용자(연구자)들 측면에서도 연구자들이 기록을 고정된 해석의 프레임에 맞추거나, 자신의 해석에 따라 선별적으로 이용한다는 비판이 제기되어 왔다. 인천지역의 동일방직, 반도상사, 대한마이크로 등 노동조합 사례와 구로동맹파업의 사례 등을 통해 살펴보았을 때 기록의 생산과 활용 사이에서 발생하는 문제점은 분명하게 드러났다. 70년대 민주노조운동의 당사자들 사이에서도 역사적 기록에 '승리자'로 남는 그룹이 있는 반면에, 부당하게 '실패자'로 낙인찍히는 '중층적 주변화' 현상이 발생해 왔다. 연구자들의 적극적인 개입은 매우 제한적일 뿐이고, 시민과 노동자들 사이에서 이런 '기억투쟁'이 원활하게 해결되어 나갈 방법은 보이지 않는다. 이는 노동아카이브가 지역 속에 뿌리내리지 못하는 하나의 원인이 되고 있다. 본 논문은 참여형 노동아카이브의 구축을 통해서 기록 생산과 활용에 대한 대안적인 방법론을 제시하였다. 더 나아가 참여의 이론적인 부분을 보완하여 '로컬리티 기록화' 전략의 구체적 방향성을 모색하였다. 로컬과 로컬리티 연구는 비단 물리적 공간의 문제만이 아니다. 그것은 기억과 정체성, 그리고 사회적 관계를 구성해가는 과정에서 발생하는 '다중적 스케일'(multi-scalar) 접근 방법을 요청한다. 대안적인 '로컬리티 기록화' 전략은 기존의 노동아카이브가 해결해야 하는 기록 생산과 활용 사이의 문제점을 해소하는 데 기여할 것이다.

Purpose: The aim of the study was to evaluate the effect of self-monitoring of blood glucose (SMBG)-based Diabetes Self-Management Education (DSME) on glycemic control in type 2 diabetes. Methods: This study was designed to compare changes in glycemic control over 12months in SMBG-based DSME group (n=65) versus control group (n=65). Data were obtained from medical records type 2 diabetic patients treated with oral antidiabetic agents and above HbA1c 7.0% from June 2006 to August 2008. All participants completed DSME defined as informational intervention of lifestyle habits and reinforcement of educational Monthly News letter delivered by the diabetes nurse educator. SMBG-based DSME group requested to measure blood glucose 7 times a day for a week and to record their diary and received counseling with a focus on diet and lifestyle during the education. Assessments were conducted baseline, 3, 6 and 12 months. HbA1c was used as an index of glycemic control. Results: 12 months later, the level of HbA1c was reduced by $1.28{\pm}1.68%$ in experimental group and $0.49{\pm}1.05%$ in the control group. We found a significant effect of $Time^*$ Group interaction (p=.013). Conclusion: SMBG-based DSME for patients with type 2 diabetes with oral antidiabetic agents was effective in improving glycemic control and maintaining long-term glycemic control.

The purpose of this study was to standardized and classify the coordination pattern among the chewing side and non-chewing side masseter and anterior muscles, in terms of EMG values on lateral excursion, clenching, and mastication in presence of the non-chewing side. In this study, 25 subjects were selected for experiment of lateral excursion, clenching and mastication and EMG value of the masseter and anterior temporal muscle on both sides were recored 2 times respectively. The bioelectric processor model EM2(Myo-tonic research, INC. U.S.A.) with the surface electrodes were used to record the EMG activity during all experimental procedures. The results were as follows : 1. During lateral excursion on intereference of non-chewing side, the EMG values of the temporal muscle were significantly more prominent than those of the temporal muscle on the non-chewing side. The EMG values of non-chewing side were significantly more prominent than those of chewing side on the both side masseter muscle and those of chewing side were significantly more prominent than those of non-chewing side on the both side temporal muscle. 2. During clenching on the occlusal interferance, the EMG values of non-chewing side masseter muscle were most prominent. 3. During mastication on the occlusal interferance, the EMG values of the chewing side temporal muscle were most prominent and those of non-chewing side temporal muscle were the lowest. 4. The EMG values of temporal muscle of non-chewing side on interferance were significantly more prominent than those of canine guidance during lateral excursion. 5. During clenching on the occlusal interferance, the EMG values of the masseter and the temporal muscles of the non-chewing side were significantly more prominent than canine guidance, but those of chewing side temporal muscle on canine guidance were significantly more prominent than those of interferance. 6. During mastication on canine guidance, the EMG Values of the temporal muscle on the chewing side, the masseter muscle on the chewing side and the temporal muscle on the non-chewing side were more prominent than those of interferance, but temporal muscle of non-chewing side was not different between canine guidance and occlusal interferance on non-chewing side.

This study was performed to investigate the clinical features of internal derangement of temporomandibular joint. For this study, 117 patients with temporomandibular disorders and 81 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the control group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, maximal mouth opening range, and affected side were recorded clinically. Head and shouldeer posture was measured in a groundplate on which square diagram of five centimeters each had been drawn, and cephalograph was also taken for measurement of head and neck posture. Sonopak of Biopak system (Bioresearch inc., USA) was used to record joint vibration for evaluation of internal healthy status of temporomandibular joint. The data collected were analyzed by SAS statistical program. The results of this study were as follows : 1. Frequency of left side chewing subjects was higher in patients than in control group, but there was no difference in distribution of subjects by Angle's classification. Other types was prvalent in patients whereas group function was more in control group for lateral guidance pattern. 2. As to lateral guidance pattern by clinical diagnosis, patients with internal derangement and/or degenerative joint disease showed higher frequency was consistent with the result by Sonopak impression. 3. There was no difference for shoulder height between the two groups, however, tilting of head and backward extension of cervical spine was more frequent in control group. 4. Acromion was positioned more anteriorly in patients with internal derangement and/or degenerative joint disease than in control group and angle between eye and tragus was larger in patients. Patients with degenerative joint disease showed more flexed head posture than control group did in cephalometric profile. 5. Maximal mouth opening range in patients with internal derangement was the least in all subgroups in patients classified by Sonopak impression.

Purpose: The aim of this study was to compare retrospectively the efficacy of anti-osteoporotic agents (RAL-Raloxifene 60 mg, ALD-weekly alendronate 70 mg, RSD-weekly risedronate 35 mg, AVD3-weekly alendronate 70 mg/vitamin $D_3$ 2800IU, IBD-quarterly IV ibandronate 3 mg/3 ml, ZLD-yearly IV zoledronate 5 mg/100 ml) in postmenopausal patients with osteoporosis or osteopenia. Method: This study retrospectively reviewed medical record and compared the lumbar spine BMD percentage changes of each medicine group one year later from the baseline. 209 patients (27, 50, 60, 30, 35, and 7 patients in RAL, ALD, RSD, AVD3, IBD, and ZLD groups, respectively) are within the inclusion criteria for the study. Results: From baseline to month 12, lumbar spine BMD increased significantly larger with bisphosphonate groups, compared to SERM (p < 0.05). In all bisphosphonate groups, the lumbar spine BMD were increased significantly from baseline. Of the bisphosphonates, the changes from baseline in BMD of IV bisphosphonates were more larger than those of oral bisphosphonates, and yearly, quarterly bisphosphonates yielded significantly greater BMD gains, compared with weekly bisphosphonate groups (p<0.05). In addition, patients receiving 70 mg weekly alendronate+vitamin D3 had greater gains in BMD than alendronate Single preparation (p<0.05). Conclusion: Bisphosphonates yielded significantly greater BMD gains than SERM. Of the bisphosphonates, the changes from baseline in BMD of yearly, quarterly IV bisphosphonates yielded significantly greater BMD gains, compared with weekly oral bisphosphonate groups. In addition, vitamin D3 plays an significant role in BMD gains.
