목적 : 본 연구는 재활·요양병원 환자의 사회적 입원이 증가하고 있는 현상에 대해 작업치료사의 관점에서 분석하고자 하였다. 연구방법 : 작업치료사들의 관점을 확인하기 위하여 재활 서비스 평가 도구 RSAT를 기반으로 주관식 설문지를 구성하였고, 2019년 8월 전국 3년차 이상의 작업치료들에게 설문지를 배포 및 수거하였다. 설문지의 응답자료를 van Kaam의 현상학적 연구 방법을 통해 분석하였고, 유효 세부서술에 대해 Word cloud로 다빈도 단어를 분석하였다. 결과 : 배포한 설문지는 수도권, 충청권, 경상권에서 46명의 작업치료사들로부터 응답을 받았다. 설문지의 응답자료는 2개의 범주(categories)와 4개의 주제(theme), 13개의 하위주제(subtheme)로 분석되었다. 2개 범주는 '병원의 체계'와 '작업치료 임상의 내·외부적 요인'으로 나타났으며 '병원의 체계'에 따른 주제는 '다학제 팀 접근의 어려움'과 '퇴원계획 체계의 미흡'으로 나타났다. '작업치료 임상의 내·외부적 요인'에 따른 주제로는 '작업치료사의 어려움'과 '작업치료 실시의 어려움'으로 분석되었다. 결론 : 작업치료사들은 재활·요양병원 환자들의 지역사회 복귀가 어려운 가장 큰 원인이 합리적이지 못한 작업치료 관련 요양급여체계에 있다고 지적하였다. 퇴원 및 지역사회 적응을 위한 작업치료 서비스 체계의 미흡함 역시 환자들로 하여금 퇴원하지 못하고 결국 다시 병원으로의 입원을 하게 만드는 주요 원인의 하나로 인식하고 있었다. 향후 작업치료 처방 및 의료 급여 체계를 환자의 재활 목적에 맞도록 다면화할 필요가 있음을 제언한다.

Background and Objectives : After thyroidectomy, many patients experience problems report such things as reduced voice range and vocal fatigue, swallowing problems without superior and recurrent laryngeal nerve injury. The purpose of this study was to evaluate voice and swallowing problems before and after thyroid surgery without laryngeal nerve injury. Materials and Methods : Ninety-three patients who underwent thyroidectomy without laryngeal nerve injury and completed the follow-up evaluations were studied between June 2013 and December 2015. Each evaluation was performed preoperatively, as well as 1 week, 1 month postoperatively. Analysis was performed including voice handicap index (VHI), dysphagia handicap index (DHI), and acoustic voice analysis. Results : Patients show significant variation of parameters in the fundamental frequency (F), maximal phonation time (MPT), shimmer, jitter and soft phonation index (SPI) early after operation, and most of them showed recovery of parameters after 1month of operation. Perceptive complaint of voice and swallowing also showed significant decreased after operation (p<0.005). After 1month of operation, MPT, highest frequency and frequency ranges still showed significant decreased parameters. Comparing acoustic and perceptive parameters of total thyroidectomy and lobectomy, there was no significant changes between them except highest frequency (p=0.042). Conclusion : The results from both subjective and objective evaluations show voice and swallowing disturbance after thyroidectomy even in the absence of laryngeal nerve and provide patients information about the recovery process after surgery. Highest frequency parameter showed most significant changes after operation.

Background: The objective of the study was to determine the knowledge, attitude and behaviors of the practicing dentists regarding tobacco cessation counseling (TCC) in Chhattisgarh state and also the barriers that prevent them from doing so. Materials and Methods: The study was conducted among dental practitioners of Raipur district, Chhattisgarh state (India). The sampling frame was registration with the State Dental Council and practicing in Raipur district. A questionnaire was personally administered and the practitioners were given explanations regarding how to complete it. Only descriptive statistics were calculated (SPSS version 16 for Windows). Results: Based on the responding dentists' self reports, 76% were not confident in TCC, 48% did not assume TCC to be their responsibility, 17% considered that it might have a negative impact on their clinical practice, whereas 24% considered it might take away precious time from their practice, 25% considered TCC by dentists to be effective to a considerable extent and 80% considered TCC activities are not effective due to lack of formal training, 69% considered dental clinics as an appropriate place for TCC but 82% thought there must be separate TCC centre and 100% of the dentists wanted TCC training to be a part of practice and that it should be included in dental curriculum. Some 95% of them were of the view that tobacco products should be banned in India and 86% responded that health professionals must refrain from tobacco habits so to act as role models for society. Conclusions: Dental professionals must expand their armamentarium to include TCC strategies in their clinical practice. The dental institutions should include TCC in the curriculum and the dental professionals at the primary and the community health care level should also be trained in TCC to treat tobacco dependence.

Objective: This study aimed to examine the characteristics of joint kinematics and synchronicity of rowing motion between elite and non-elite rowers. Methods: Two elite and two non-elite rowers performed rowing strokes (3 trials, 20 strokes in each trial) at three different stroke rates (20, 30, 40 stroke/min) on two stationary rowing ergometers. The rowing motions of the rowers were captured using a 3-dimensional motion analysis system (8-infrared camera VICON system, Oxford, UK). The range of motion (RoM) of the knee, hip, and elbow joints on the sagittal plane, the lead time ($T_{Lead}$) and the drive time $T_{Drive}$) for each joint, and the elapsed time for the knee joint to maintain a fully extended position ($T_{Knee}$) during the stroke were analyzed and compared between elite and non-elite rowers. Synchronicity of the rowing motion within and between groups was examined using coefficients of variation (CV) of the $T_{Drive}$ for each joint. Results: Regardless of the stroke rate, the RoM of all joints were greater for the elite than for non-elite rowers, except for the RoMs of the knee joint at 30 stroke/min and the elbow joint at 40 stroke/min (p < .05). Although the $T_{Lead}$ at all stroke rates were the same between the groups, the $T_{Drive}$ for each joint was shorter for the elite than for the non-elite rowers. During the drive phase, elite rowers kept the fully extended knee joint angle longer than the non-elite rowers (p < .05). The CV values of the TDrive within each group were smaller for the elite compared with non-elite rowers, except for the CV values of the hip at all stroke/min and elbow at 40 stroke/min. Conclusion: The elite, compared with non-elite, rowers seem to be able to perform more powerful and efficient rowing strokes with large RoM and a short $T_{Drive}$ with the same $T_{Lead}$.

Objective: This study was conducted to compare morphological defects, viability, motility (MOT), fertility (F), and hatchability (H) in four Korean native chicken breeds (KNCBs), and to evaluate whether defective segments of spermatozoa are associated with MOT, F, and H. Methods: Four KNCBs, including Korean Ogye (KO), Hwangbong (HB), Hyunin Black (HH), and Hoengseong Yakdak (HY) were used. White Leghorn (WL) was used as a control. Nine cocks from each breed were randomly assigned into three groups. Semen was collected by abdominal massage method. Eosin-nigrosin staining method was used to identify live-dead spermatozoa. Different segments and specific morphological defects of spermatozoa were identified using 4', 6-diamidino-2-phenylidole and MitoTracker Red CMXRos. F and H rates were evaluated following artificial insemination (AI). Results: KO had the highest MOT rate compared to HY. Viable normal sperm rates of KO and HH were high and comparable with WL. HY spermatozoa had the highest viable abnormal sperm (VAS) or morphological defect rate followed by HB. Likewise, HB spermatozoa had the highest dead sperm (dead) rate compared to KO, HY, and WL. Bent, coiled, detached, broken, and knotted were common identified specific morphological defects for all breeds. Most morphological defects were at the head and tail in all breeds. VAS showed strong negative correlation with MOT (r = -0.697) and F (r = -0.609). Similarly, defective tail was negatively correlated with MOT (r = -0.587), F (r = -0.797), and H (r = -0.448). The F and H rates of KO and WL were comparable. Conclusion: These data indicate that most identified specific morphological defects are at the head and tail. VAS and defective tail were associated with poor motility, F, and H. KNCBs showed more morphological defects than WL. Finally, these results will facilitate successful AI and semen cryopreservation.

CFC-113과 1,1,1-trichloroethane 등과 같은 CFC 화합물은 화학적 안정성 및 열역학적 특성 등이 우수하고, 불연성이며, 부식성이 없는 화합물로 오랜 시간 동안 전 산업에 걸쳐 널리 사용 되어 왔다. 하지만, 1989년 지구 환경의 보호를 위해 이들의 생산과 사용을 규제하는 국제협약인 '오존층 파괴물질에 관한 몬트리올 의정서'가 체결되어 대체 세정제가 요구되고 있다. 본 연구에서는 세정 시스템을 변화시키지 않고 세정력이 우수하면서 환경 친화적이며 인체 유해도가 낮으며 부식성 물질을 발생 시키지 않는 비수계 세정제를 개발하고자 하였다. 이를 위하여 글리콜 에테르계의 용매와 파라핀계 탄화수소 물질을 일정 비율로 혼합, 배합하면서 실록산을 첨가하여 비수계 세정제를 배합 제조하였다. 그리고 이들 세정제의 물성과 세정성을 평가하여 대체 세정제로서의 가능성을 평가하였다. 배합세정제의 물성측정 결과 밀도와 표면장력이 낮아 오염물에 대한 침투력이 우수할 것으로 예상되었고 인화점과 증기압 측정값으로 세정제의 안전성을 평가할 수 있었다. 플럭스, 솔더 및 그리스에 대한 세정성능 측정결과 높은 세정성능을 보여주었고 피세정물의 표면에 잔류물이 생성되지 않았다. 결과적으로, 규제물질과 동등한 세정능력을 지니며 침투력이 우수하고 인체 유해도가 낮은 세정제를 개발할 수 있었다.

Objective : This study is designed to present the direction and the necessity of education on the biomedical ethics the establish desirable ethical view of paramedic students by understanding on the consciousness of students of department of emergency medical technology on biomedical ethics on euthanasia. Method : Data were collected from on 335 students of department of emergency medical technology in 4-year-college located in districts of Chungcheong-do, from March 4 to April 22, 2010. The questionnaire consisted of total 29 items, i.e., 11 items of general characteristics, 11 items of characteristics related to biomedical ethics and 7 items of consciousness on euthanasia. Result : In general characteristics, the first grade showed the most dense distribution of 37.3%, the second grade was 20.0%, the third grade was 20.9% and the fourth grade was 21.8%. In the consciousness of biomedical ethics on euthanasia, the third and the fourth grades showed a higher ratio(${\chi}^2$ = 136.327, p= .000), in comparison with the first and the second grades, the higher year they were, the higher degree of consciousness they had. The consciousness on each item of euthanasia showed significant differences in grade (F = 8.203, p= .000), experience of clinical practice or none (t = 3.731, p= .000), experience of biomedical ethics education or none (t = 1.997, p = .047) and degree of consciousness on DNR (F = 8.240, p = .000) regarding 'CPR shall not be required in any cases if a patient wants DNR', in experience of biomedical ethics education or none (t = 2.452, p= .015) and degree of consciousness on DNR (F = 2.725, p = .044) regarding if a patient refuses all treatments, the patient's opinion shall be respected', and in degree of consciousness on DNR (F = 2.858, p = . 037) regarding 'after determination of DNR, if the family wants a positive treatment, it shall follow the family's request'. Conclusion : It seemed that the differences in consciousness according to grade and experience of clinical practice were influenced by experiences to treat patients in personally. Moreover, it showed that the higher grade they are, the more experience of education they have, the experiences of education had influences on the consciousness. Development of educational programs is required in order to supply accurate knowledge on biomedical ethics for euthanasia to lower-grade students the to let them establish ethical views properly, and in order to correct wrong knowledge and to establish ethical views while supplying knowledge on biomedical ethics for euthanasia to higher-grade students.

Purpose: The purpose of this study was to investigate the level of clinical image quality of panoramic radiographs and to analyze the parameters that influence the overall image quality. Materials and Methods: Korean dental clinics were asked to provide three randomly selected panoramic radiographs. An oral and maxillofacial radiology specialist evaluated those images using our self-developed Clinical Image Quality Evaluation Chart. Three evaluators classified the overall image quality of the panoramic radiographs and evaluated the causes of imaging errors. Results: A total of 297 panoramic radiographs were collected from 99 dental hospitals and clinics. The mean of the scores according to the Clinical Image Quality Evaluation Chart was 79.9. In the classification of the overall image quality, 17 images were deemed 'optimal for obtaining diagnostic information,' 153 were 'adequate for diagnosis,' 109 were 'poor but diagnosable,' and nine were 'unrecognizable and too poor for diagnosis'. The results of the analysis of the causes of the errors in all the images are as follows: 139 errors in the positioning, 135 in the processing, 50 from the radiographic unit, and 13 due to anatomic abnormality. Conclusion: Panoramic radiographs taken at local dental clinics generally have a normal or higher-level image quality. Principal factors affecting image quality were positioning of the patient and image density, sharpness, and contrast. Therefore, when images are taken, the patient position should be adjusted with great care. Also, standardizing objective criteria of image density, sharpness, and contrast is required to evaluate image quality effectively.
