Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is an ulcerative lesion on oral mucosa featuring as a benign mass of self-limiting growth. It can be easily misdiagnosed as squamous cell carcinoma (SCC) due to its long healing period and elevated or rolled-up margin. A 57-year old male patient who visited our department was diagnosed as SCC according to the clinical features, results of positron emission tomography (PET) and magnetic resonance imaging (MRI) of the oral lesion. However, after performing incisional biopsy, histopathologically, there were no atypical cells, but eosinophil and CD 30+ T-cells were clustered in subcutaneous and muscle tissue. It is very significant to consider this reactive lesion in the field of oral and maxillofacial surgery because of its possibility of mistaken as malignant disease. Here, we will report a couple of cases of TUGSE with references and limit of radiographic tools used for diagnosis of head and neck cancer.

가우시안의 차를 이용하여 검색속도를 향상한 최소 오디오 핑거프린팅

권진만(Jin-Man Kwon),고일주(Il-Ju Ko),장대식(Dae-Sik Jang) 한국컴퓨터정보학회 2009 韓國컴퓨터情報學會論文誌 Vol.14 No.12

본 논문은 오디오 핑거프린트 데이터 생성 방법과 이를 이용한 오디오 데이터 비교 방법에 관한 것으로서, 오디오 데이터의 특징을 이용하여 음악을 식별하는 방법을 제시한다. 일반적으로 영상인식을 위해 많이 사용되는 가우시안의 차(Difference of Gaussian, DoG)를 오디오 데이터에 적용하여 음악이 급진적으로 변하는 부분을 추출하고, 해당 위치를 핑거프린트로 정의하는 방식이다. 이렇게 만들어진 핑거프린트는 음질의 변화에 민감하지 않으며, 음악 데이터의 일정 부분만으로도 원본과 동일 위치의 핑거프린트 추출이 가능하다. 이 시스템은 기존의 주파수 영역을 이용한 시스템 보다 오디오 핑거프린트의 데이터량과 계산량을 줄여줌으로써 검색을 할 때 보다 효율적인 성능을 나타낸다. 이를 응용하여 인터넷에 유통되는 복사된 음악의 저작권 보호, 또는 음악의 메타정보 등을 사용자에게 나타낼 수 있다. This paper, which is about the method of creating the audio fingerprint and comparing with the audio data, presents how to distinguish music using the characteristics of audio data. It is a process of applying the Difference of Gaussian (DoG: generally used for recognizing images) to the audio data, and to extract the music that changes radically, and to define the location of fingerprint. This fingerprint is made insensitive to the changes of sound, and is possible to extract the same location of original fingerprint with just a portion of music data. By reducing the data and calculation of fingerprint, this system indicates more efficiency than the pre-system which uses pre-frequency domain. Adopting this, it is possible to indicate the copyrighted music distributed in internet, or meta information of music to users.

본 연구는 자료포락분석(DEA : Data Envelopment Analysis)을 이용하여 선진기업복지제도 실행에 따른 경제적 효과성을 분석하여, 중소기업들이 선진기업복지제도를 적극 도입 시행하도록 기여하는데 그 목적이 있다. 이를 위해, 설문회수 자료 중 투입-산출 지표와 관련된 3가지 유형의 - A유형(기본+심화, 도입)기업 36개, B유형(기본+심화, 미도입)기업 5개, C유형(기본, 미도입)기업 7개 - 총 48개 기업을 표본대상으로 하여 선진기업복지제도 도입과 관련된 경제적 효과성을 측정해 보았다. 분석 결과, 컨설팅을 받은 후 선진기업복지제도 중 어떤 하나의 제도라도 도입한 기업의 경제적 효과성이 컨설팅을 받은 후 관련 제도를 도입하지 않은 기업의 경제적 효과성보다 대체로 높게 나타나, 근로복지공단에서 실시하는 컨설팅을 통해 제도를 도입할 경우 긍정적인 경제적인 효과가 있음을 확인할 수 있었다. 이러한 연구결과를 통해 근로복지공단에서는 컨설팅을 보다 적극적으로 실시할 필요가 있으며 컨설팅만 받고 관련 제도 도입을 망설이는 기업을 찾아내고 그 이유에 대하여 구체적으로 파악해 볼 필요가 있음을 시사하고 있다. The purpose of this study is to analyze the economic effectiveness of advanced enterprise welfare system utilizing DEA(Data Envelopment Analysis) and contribute to the adoption and implementation of the system conducted by Korea Workers’ Compensation & Welfare Service(COMWEL). We classified 48 sample data into 3 categories : A category(basic consulting & intensive consulting, adoption) is 36, B category(basic consulting & intensive consulting, non-adoption) is 5, and C category(only basic consulting, adoption) is 7. A consulting fee is used as input variable, earning per employee and average employee tenure are used as output variables. As a result from DEA, we find out the fact that the economic effectiveness of A category is better than the economic effectiveness of B and C category and it comes to the conclusion that the consulting service provided by COMWEL has a positive effect on the adoption and implementation of advanced enterprise welfare system. Therefore, COMWEL is required to perform consulting service to small & medium business more actively and is needed to look at the reason why some businesses hesitate to accept the relevant system.

Glandular odontogenic cyst (GOC) is an intraoral cyst originated from serre remnants which has incidence of rare frequency. Only 111 cases have been reported since Gardener first introduced it in 1987. The clinical features are the following components: cortical bone thinning, locally aggressive root resorption, non-painful swelling. The following recurrences rate are 64.3% in conservative treatment, and 0% in wide excision for instance, segmental or marginal mandibulectomy. So, its prognosis is similar to that of odontogenic keratocyst and ameloblastoma. Therefore, periodic recall follow ups are essential to detect disease recurrence. Here, we will report the first case of GOC diagnosed in our department considering with references. And we share this treatment experience because these aggessive lesions may be misjudged for simple dental cyst.

Traumatic lacerations are common in the orofacial region as a result of accidents. Due to the frequent movement of the skin around the mandible, scars in that area are more likely to widen or become hypertrophic. Treatment of facial laceration was performed on three patients and followed by regular check-up. It was discovered that the scars have become hypertrophic, so steroid injections were used. The results were satisfactory with the decrease in sizes and hardnes of the scar. Facial scarring is a particularly distressing phenomenon and has always been a challenge to treat as the scars are more likely to widen or become hyphertrophied due to the frequent movement of the muscle in the facial area. We confirmed that the positive effect of steroid on hypertrophic scars. So, we suggest that proper treatment and periodic follow-up, adjuvant treatments especially steroid injection is necessary in patients with lacerations.

박경일(Kyung Il Park),권진아(Jin A Kwon),김정근(Jeong Keun Kim) 한국노인복지학회 2014 노인복지연구 Vol.0 No.63

본 연구는 부산지역 노인요양시설에 종사하는 요양보호사 295명을 대상으로 갈등과 돌봄 태도가 이직의도에 어떠한 영향을 미치며 갈등과 돌봄 태도는 직무스트레스를 매개로 하여 노인요양시설 요양보호사의 이직의도에 어떠한 영향력을 미치는지를 검증하는데 그 목적이 있다. 나아가 본 연구는 요양보호사의 이직의도를 완화시킬 수 있는 사회복지적 실천방안을 모색하는데 기여하고자 한다. 본 연구의 주요 연구 결과는 다음과 같다. 첫째, 노인요양시설 요양보호사가 인식하는 요양보호사의 갈등수준은 3.53, 노인돌봄태도는 5.72점, 직무스트레스 수준은 3.58점, 이직의도는 3.46점 수준으로 노인돌봄태도가 다소 높은 수준으로 나타났다. 둘째, 노인요양시설 요양보호사의 개인적 갈등과 개인 간 갈등이 심할수록, 노인돌봄태도가 부정적일수록 이직의도는 높아지는 것으로 나타났다. 셋째, 갈등은 직무스트레스를 완전매개로하여, 노인돌봄태도는 직무스트레스를 부분매개로 하여 이직의도에 영향력을 미치는 것으로 분석되었다. 이러한 연구결과를 바탕으로 직원의 업무참여를 통한 직원 간 갈등 해소, 정기적인 교육프로그램 실시로 요양보호사들의 노인돌봄의식 향상, 적절한 업무분장으로 직무스트레스를 감소시키는 방안을 제언함으로써 노인요양시설 요양보호사의 이직의도를 감소시켜 노인요양시설의 서비스 질과 직무만족을 향상시키는데 기여하고자 한다. This study aims to prove how the elderly caregivers’ conflicts against the elderly and their care attitudes influence on the caregivers’ turnover intention and how the job stress is mediated their conflicts against the elderly and how the both variables (conflicts and care attitudes) influence on their turnover by mediating the job stress, targeting 295 elderly caregivers working in some elderly nursing homes located in Busan. Main results of this study are as follows: First, it was found that the conflict level perceived by caregivers working elderly nursing homes was scored to 3.53 point, and their care attitude level was 5.72 point, and their job stress level was 3.58 point, and their turnover intention level was 3.46 point, therefore the elderly caregivers’ care attitude for elderly people was somewhat higher than the other variables. Second, it was identified that as an elderly caregivers’ intra conflict and internal conflict were more serious and his/her care attitude was more negative, then his/her turnover intention became higher. Third, it was analyzed the conflict influenced on the elderly caregivers’ turnover intention by fully mediating the job stress, and their care attitude did so by partly mediating the job stress. Based on the results, this study tries suggests a way to reduce the elderly care helpers’ job stress by resolving the employees’ conflicts through their work participation, improving the elderly care sense for elderly people through regular educational programs, and appropriately distributing works.

이승준(Seung-June Lee),권진일(Jin-il Kwon),임경민(Kyung-Min Lim),김형준(Hyung Jun Kim),차인호(In-Ho Cha),남웅(Woong Nam) 대한구강악안면외과학회 2010 대한구강악안면외과학회지 Vol.36 No.5

Fleischmann et al. first described the concept of using sub-atmospheric pressure to treat open or infected wounds in 1993. Since then, Argenta and Morykwas developed subatmospheric, or negative pressure dressings in 1997 as a means of managing complicated wounds. Since its introduction in 1997, the vacuum-assisted closure (VAC) system has been used widely in general plastic surgery, general surgery, and orthopedic surgery to manage complicated wounds of the torso and extremities. However, there is a paucity of literature describing its use in the head and neck region, particularly in oral and maxillofacial surgery. We report a successful case of postoperative orocutaneous fistula closure using a VAC system in a 59-year male with a review of the relevant literature.
