Background: Ameloblastoma are benign but locally invasive neoplasms that represent 10% of all odontogenic tumors. Despite its benign characteristics, ameloblastoma has a high recurrence rate after treatment with a recurrence rate of 55-90%. It is important to identify the risk factors of recurrence to improve patient’s quality of life in oral and maxillofacial surgery. Methods: Patients who underwent surgery at the Department of Oral and Maxillofacial Surgery at Pusan National University Dental Hospital for 5 years from 2017-2021 and were diagnosed with ameloblastoma as a result of postoperative histological examination were included. The patients were divided into two groups, recurrent and non-recurrent, and comparative analysis was performed according to various factors. Results: First, when the lesion was involved with the inferior alveolar nerve (IAN), recurrence was more likely than when it was not. Next, recurrence occurs more often when cortical bone perforation is observed than when it is not. In particular, when resorption is shown on the lingual cortical bone, a remarkable tendency of recurrence is shown. Moreover, in radiographic characteristics, the multicystic type showed a higher recurrence tendency than the unicystic type. Conclusion: When the lesion is multicystic, perforating the cortical bone, infiltrating the adjacent soft tissue, or involving the IAN, a high recurrence rate is shown. The results of this retrospective analysis of the recurrence trend of ameloblastoma over a 5 years period are to contribute significantly to insight and reduction of recurrence rates in treatment for polymorphic lesion in oral and maxillofacial area.

This study aimed to identify prognostic factors and describe the treatment outcomes of multidrug therapy in dogs with meningoencephalomyelitis of unknown etiology (MUE). A total of 23 dogs diagnosed with MUE were treated with prednisolone in combination with cyclosporine, cytosine arabinoside (CA), leflunomide, and mycophenolate mofetil. Based on the survival time, these dogs were divided into two groups: group A (n = 10), surviving for < 100 days, and group B (n = 13), surviving for > 100 days. Signalment, seizure activity, cerebrospinal fluid (CSF) analysis results, and magnetic resonance (MR) imaging findings were reviewed. Survival studies were conducted to investigate the association of each prognostic factor and treatment with the clinical outcome. There were no significant differences in age, sex, body weight, occurrence of seizures, cell number and protein concentration in the CSF, or location of lesions between groups A and B. Abnormal MR features were more frequently observed in group A than in group B. It was identified that the longest median survival time was administration of multi-drug therapy including CA. In conclusion, abnormal MR features were associated with poor prognosis in dogs with MUE and CA-based multi-drug therapy could be considered the most effective treatment of MUE.

This paper investigates Korean EFL students’ learning (de)motivation factors according to the level of students’ English learning motivation. A total of 41 undergraduate students reflected on their past ten years of English learning experiences and submitted autobiographic essays with ‘motigraph,’ marking their annual changes of English learning motivation from 0 to 10. The data were analyzed with Grounded Theory. The findings revealed that the factors that increased or decreased English learning motivation were different according to students’ level of motivation. Students with low-level motivation were influenced by their teacher or parents, while those with high-level motivation were influenced by their past L2 learning experiences perceived positively by themselves. In both groups, the factors of emotional experiences caused by negative L2 learning experiences were the main reasons for demotivation. This paper emphasizes the importance of subjective appraisal in maintaining students’ L2 learning motivation and recovering from the state of demotivation.

목적 : 본 연구는 산재 수부손상환자들을 대상으로 수부재활치료를 시작하는 시기가 손 기능에 미치는 영향을 알아보고자 하였다. 연구방법 : 본 연구는 후향적 코호트 연구(retrospective cohort study)로 전자의무기록(electronic medical record)을 활용하였다. 2018년 1월부터 2019년 12월까지 경남 창원의 C 병원과 전남 순천의 S 병원에서 수부재활치료를 받은 환자 127명을 대상으로 치료시기에 따른 손 기능 차이를 알아보기 위해 손상 후 4개월 이전(61명)과 4개월 이상(66명) 두 그룹으로 나누어 장악력, 집기, 휴식 시 통증, 활동 시 통증, Jebsen- Taylor Hand Function Test(JTHFT), Quick DASH를 비교하였다. 결과 : 산재 수부손상환자에게 수부재활치료를 제공하였을 때 두 그룹 모두 손 기능이 유의하게 향상이 되었다(p < .05). 그룹 간 손 기능 변화량 비교에서는 장악력 검사, 측면집기, 휴식 시 통증, 활동 시 통 증, Quick DASH에서 4개월 이전 그룹이 4개월 이상 그룹보다 통계적으로 유의한 향상이 있었다(p < .05). 결론 : 본 연구 결과를 통해 치료시기가 빠를수록 손 기능 향상에 긍정적인 영향을 미치는 것을 알 수 있 었다. 따라서 수술 이후 산재수부손상 환자에게 초기재활에 대한 정보제공과 진단명, 손상부위, 손상정도에 따른 적절한 치료가 필요함을 제시하였다.

Background: Health-related quality of life (HRQOL) is a construct of quality of life relevant to health. HRQOL can be measured multiple ways including self-perceived interpretation of one’s health status. Research has shown value in understanding self-perceived or person-centered HRQOL. Thus, these types of assessments have been integrated into health care systems, used to help patients set personal goals and to determine treatment success. The purpose of this study was to describe the group, examine the relationship between HRQOL and functional independence, and then determine the impact of standard care on the HRQOL (index and visual analog scale [VAS]). Methods: Retrospective clinical observation study. Descriptive statistics used to describe the stroke sample. Comparison was performed to explore the correlation between the EuroQol 5-Dimensions Questionnaire (EQ-5D) and the Functional Independence Measure (FIM) at admission and discharge. Paired-samples t-test was conducted to evaluate the impact of standard therapy on HRQOL on EQ-5D. Results: n=1325; mean age of 72 years (SD=13.28) and 65% females. A weak, positive correlation found at admission (r=.15, n=1325, p<.000) and discharge (r=.04, n=1325, p<.000). A paired-samples t-test revealed a statistically significant increase in HRQOL index and VAS scores (p’s<.000) overtime, with a large effect size (η2=.74 and .70), respectively. Conclusion: A weak relationship was present between HRQOL and functional independence, thus suggesting these assessments should be used independent of each other. Statistically significant change in scores suggest improvement in HRQOL overtime, supported by large effect sizes and mean scores higher than the minimal important difference range.

The vascular origin diseases occurring in the oral and maxillofacial region can be divided into hemangiomas and vascular malformation. They are rare and early lesions are not easy to diagnosis, so they may be misdiagnosed as clinicians, or the method and timing of treatment may be inappropriate. For 10 years, from August 2005 to August 2015, we analyzed the clinical records, diagnosis, treatment, and prognosis of 23 patients with hemangioma or vascular malformation confirmed by clinical, histopathological or radiological examination of maxillofacial lesions at department of oral and maxillofacial surgery, Pusan National University Hospital and Pusan National University Dental Hospital. Chief complants of patients were mainly swelling, mass, and spot-like lesion on various intraoral sites. Treatments were performed with excision, embolization, sclerotherapy, depending on each lesions condition. Arteriovenous malformation cases were more frequently recurred than other lesions. Prognosis of lesions were relatively good but close observation should be needed.

Echocardiography is one of the most useful diagnostic techniques for differentiating heart disease as well as mitral valve lesion. Forty client-owned small breed dogs (weight, 2.3−13.2 kg) aged between 8−17 years with myxomatous mitral valve degeneration (MMVD) were included in the present study. The diagnosis of MMVD in dogs was made based on the clinical signs, chest radiography data, and echocardiographic findings. Echocardiographic examinations were conducted in accordance with recommended standards for dogs. M-mode, Doppler, and 2D echocardiography were performed in left and right lateral recumbency. 2D echocardiography was used to measure LA and Ao diameter from 2D short axis at the level of the aortic valve. In the comparison of conventional echocardiography indices in dogs with different stages of heart failure with MMVD, significant differences were observed in E/A ratio (p=0.005), EDV (p<0.001), EDVI (p<0.001), E-peak velocity (p= 0.001), ESV (p=0.028), ESVI (p=0.004), LA (p<0.001), LA/Ao Ratio (p<0.001), LVIDd (p<0.001), LVIDd/Ao Ratio (p<0.001), LVIDs (p=0.036), LVIDs/Ao Ratio (p=0.002), and MR Velocity (p=0.026). In addition, distinct correlations were found in EDV (r=0.712), LA/Ao ration (r=0.830), LVIDd (r=0.724), and LVIDd/Ao ratio (r=0.759). This study found that known conventional echocardiographic indices, including EDV, LA/Ao ratio, LVIDd dimension, and LVIDd/Ao ratio correlated with the severity of MMVD in point of significant differences and distinct correlations.

본 연구는 췌장암 환자가 수술 후 보조 요법으로서 항암화학요법 또는 항암-방사선병용요법을 시행받는 경우에 있어서 치료 성적의 차이가 있는지 조사하기 위해 시행하였다. 2008년에서 2012년까지 부산대학교병원에서 수술을 시행한 40명의 췌장 선암 환자들의 의무기록을 조사하였다. 근치적 목적으로 수술을 받은 환자 중 29명이 항암화학 요법 또는 항암-방사 선병용요법의 보조요법을 시행받았다. 보조요법의 시행 (p =0.025)과 완전 절제(p =0.043)가 더 긴 전체 생존기간과 연관이 있었다. 보조요법으로서 항암화학요법을 시행한 군과 항암-방사선병용요법을 시행한 군에서 전체 생존 기간은 유의하게 다르지 않았으나 보조요법을 하지 않은 군과 비교하였을 때에는 보조요법으로 항암화학요법을 시행한 군에서 유의하게 높은 전체 생존율을 보였다. 수술 후 보조요법은 췌장 선암 환자의 예후를 향상시키며, 항암화학요법이 항암-방사선 병용요법보다 양호한 결과를 보인다.

목적 : 뇌졸중 이후 우세손이 마비된 경우 기능회복 정도가 비우세손의 손상보다 더 높을 것이라는 관측이 존재하지만 이에 대한 국내 연구 자료는 부족하기 때문에 후향적 코호트 조사를 통해 우세손의 마비 유무에 따른 기능회복의 변화를 조사함으로써 작업치료 중재전략에 응용할 수 있는 자료를 제공하고자 한다. 연구방법 : 5개 의료기관에서 1차 대상자(n=205)를 모집한 후 일반적 특성 및 뇌졸중 관련 특성, 적용된 평가도구 등을 조사하고 발병일에서 초기평가일까지의 기간이 6개월 이내인 2차 대상자(n=122)를 선별하여 평가기록 자료를 수집하였다. 적용된 평가도구에 대한 빈도분석을 통하여 6개의 평가도구를 선정하였다(Modified Barthel Index; MBI, Maunual Function Test; MFT, Hand Strength Test; HST, Nine-Hole Pegboard test; NHP, Functional Independence Measure; FIM, Box and Block Test; BBT). 평가기록은 평가기간(초기, 3개월 후, 6개월 후)에 따라 자료를 수집한 후 통계학적 분석을 실시하였다. 결과 : HST, NHP, BBT에서 우세손 마비 유무에 따른 차이가 있었고(p<.001), MBI는 평가기간에 따른 차이만(p<.05) 보였으며 우세손 마비유무와 평가기간의 상호작용효과는 존재하지 않았다(p>.05). 우세손 마비 환자의 HST(lateral pinch, palmar pinch)와 BBT의 변화량은 비우세손 마비 환자보다 유의한 차이(p<.05)로 더 높았지만 그 외 평가결과에서는 통계학적 유의한 차이를 보이지 않았다(p>.05). 결론 : 본 연구를 통해 추후 뇌졸중으로 인한 편마비 환자의 다양한 작업치료 중재전략에 응용할 수 있을 것이라고 희망한다.

본 연구는 복고를 주제로 한 드라마인 <응답하라 1988>을 대상으로 주인공들과 동 시대를 경험한 연령층인 40대 시청자들이 드라마 시청을 통해 경험한 노스탤지어 가 드라마 만족과 시즌제 드라마의 후속 시청의도에 미치는 영향을 알아본 것이다. 연구결 과 시청자들의 노스탤지어 인식은 자아존중에 영향을 미치는 것으로 나타났다. 하지만 자 아존중이 후속 개념에 미치는 영향은 발견하지 못하였다. 노스탤지어는 시청자 감성에도 긍정적인 영향을 미치고 있었다. 시청자 감성은 드라마 만족도에 영향을 미치고 있었다. 시 청자 감성은 또한 후속시즌 시청의도에도 긍정적인 영향을 미치는 것을 알 수 있었다. 마지 막으로 드라마 만족도는 후속시즌 시청의도를 높이는 것으로 나타났다. 이러한 결과는 복 고 드라마의 노스탤지어의 효과에 대한 학문적인 시사점을 제공하고 시청자의 드라마 소비 에 있어 감성의 중요성을 보여주고 있다. 본 연구에서 확인한 영향 관계를 통해 노스탤지어 의 역할에 대하여 학문적으로는 물론 드라마 제작에 있어서도 일정 부분 의미를 찾을 수 있 을 것이다.

The maxillofacial region is susceptible to damage because facial bone is prominent. The aim of this study is to evaluate the incidence, etiology, seasonal distribution, and patterns of maxillofacial injuries and investigate the percentage of bone fractures on CT scans by patient’s gender and age. Electronic medical records of 1,483 patients who had maxillofacial injuries and visited the Emergency Medical Center of Chonnam National Hospital were evaluated. Age, gender, etiology, seasonal occurrence, frequency of fracture, and the pattern of bone fracture were analyzed by using IBM SPSS Statistics 21 (SPSS Inc., Chicago, IL, USA). Male to female ratio was 2.82:1. The most common causes of injury were falls or collisions (male 40.09%, female 48.2%), followed by traffic accidents and violence. The number of injuries related to sporting accidents, assult, and industrial accidents was higher in male patients than that of female patients. With regard to the seasonal occurrence, 434 cases (29.26%) occurred in the summer, while 306 cases (20.63%) occurred in the winter. In this study, 946 patients (63.79%) were identified to have facture and 537 patients (36.21%) were found to be without fracture on CT scans. The orbital bone (41.38%) was the most commonly fractured in the mid facial structures. The most common fracture site in the mandible was the body of the mandible (23.13%). The patterns of maxillofacial injuries were various based on gender, age, cause of injury, and season.

Halitosis is a bad odor in mouth. The etiology of halitosis is multifactorial including intra-oral and extra-oral causes. It affects social interactions in many people. The aim of this study is to investigate an association between recognition group and non-recognition group by evaluating halitosis level and systemic factors. Nineteen participants who visited Department of Periodontology of Seoul National University Bundang Hospital were enrolled. Volatile sulfur a compounds (VSCs) were measured by Oral ChromaⓇ, a questionnaire was requested and oral exam was carried out in all subjects. Female is more sensitive than male for oral malodor. VSCs level of hydrogen sulfide(H2S) and methyl mercaptan(CH3SH) in male is higher than that in female. Participants who gave appeal dry mouth seem to recognize halitosis.

배경/목적: 2012년 급성췌장염의 애틀랜타 분류 개정안이 발표되었고 이후 널리 이용하고 있다. 본 연구는 1992년 애틀랜타 분류와 2012년 개정안을 이용하여 급성췌장염 환자를 분류한 후 임상경과를 비교하였다. 방법: 2012년 1월부터 2013년 7월 사이 대구경북지역 6개 대형 병원에 입원한 총 574명의 급성췌장염 환자를 대상으 로 후향적 연구를 시행하였다. 1992년 애틀랜타 분류와 2012 년 개정안을 이용하여 중등도 평가를 시행하고 인구 통계 자료, 장기부전, 국소합병증, 입원기간, 임상경과 등을 분석하였다.결과: 대상 중 377명(65.7%)이 남성이었다. 연령의 중간값 은 55.4세였다. 급성췌장염의 2대 원인은 음주(238명, 41.5%)와 담석(193명, 33.6%)이었다. 2012년 개정안에 따르 면 경증췌장염은 356명(62%), 중등췌장염은 197명(34.3%), 중증췌장염은 21명(3.7%)이었다. 입원기간은 중증도 증가에 따라 통계학적으로 유의하여 증가하였다(경증 5.9일, 중 등 8.3일, 중증 13일, p <0.001). 모든 경증 및 중등췌장염 환자는 임상적으로 호전되었다. 하지만, 호전을 보이지 않은 11명은 모두 중증췌장염에 속했다. 결론: 애틀랜타 분류 개정안이 급성췌장염의 임상경과를 예측하는 데 있어 좋은 방법이다.

Allergic disorders are exaggerated immune responses to foreign antigens, regardless of the mechanism, while atopic disorders are exaggerated IgE-mediated immune responses (type I hypersensitivity). Allergic dermatitis is a common pathological condition of skin in humans and dogs. Canine allergic dermatitis presents with clinical signs similar to those reported in humans, and its causes are complex; therefore, diagnostic tests and treatments may need to be adjusted for each patient. Dogs with allergic dermatitis can suffer from secondary infections, which must be considered and confirmed or excluded for successful treatment. In this report, 35 cases of canine allergic dermatitis diagnosed using variable methods, including histological and cytological examination, are described. Patients were treated with oral or topical medications (antimicrobials, anti-inflammatories, immune modulators, topical ointments, and medicated shampoos), and their diets and environmental surroundings were also modified. This report provides an analysis of the breed, gender, age of onset, clinical signs, diagnostic methods, and treatments for canine allergic dermatitis. The information on canine allergic dermatitis presented here could be helpful in the study of human cases because these two species often share living spaces, environments, and lifestyles more closely than other animals. However, previous reports have suggested that human and canine allergies differ in some features, such as involvement of histamine in induction of pruritus, and in histopathological characteristics such as cutaneous structures.

Patients referred to the Veterinary Medical Center at Chungbuk National University were analyzed. This study aimed to provide information to clinicians in Korea on the factors affecting fracture incidence in patients adapted to Korean companion animal culture. Eighty cases showing- bone fractures were investigated from January, 2005 to De- cember, 2011. Fractures were mainly observed in miniature dogs such as Yorkshire terrier (12%), Poodle (12%), and Maltese (9%). Almost 50% of all cases were less than 1 year old. Total bone fractures in summer and fall constituted 62%. Fracture incidence was higher in male dogs (54%) than female dogs (46%). Hindlimb fracture (37%) was the most common. Distribution of limb fractures was higher in the femur (19), followed by the tibia/fibula (15), radius/ulna (13), humerus (11), and mandible (8). Pelvic fracture was observed in 19 cases. Simple fracture (84%) was the most common fracture type, followed by comminuted fracture (16%). Distal portion was the most common fracture site in long bones (67%), followed by middle (26%) and proxi- mal bones (7%). Fractures were mainly caused by traffic accidents (43%), whereas 28.5% of fractures were due to falling down. Plate & screw (26%) was the most common method of fracture repair, followed by intramedullary pin (24%), wire (11%), external skeletal fixation (10%), screw (9%), amputation (7%), cross pin (6%), IM pin and wire (5%), and rush pin (1%). Among 80 patients, 79%of pa- tients showed a good prognosis after surgery, whereas 13% patients did not experience a good result. This study shows that miniature dogs are prone to falling and fractures, espe- cially in the distal part of long bones.
