The primary intra-osseous carcinoma (PIOC) is a very rare lesion. PIOC is an odontogenic carcinoma defined as a squamous cell carcinoma arisinig within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. The authors diagnosed a 51-year-old female as primary intra-osseous carcinoma after undergoing clinical, radiological and histological examinations. The characteristics were as followed : 1. The patient complained of gingival bleeding on the premolar area in the left maxilla 2. The conventional radiograms showed a relatively well-defined unilocular radiolucent lesion from the mesial aspect of the upper left canine to the mesial aspect of the upper left 1st molar. The 2nd premolar was separated from the 1st molar and the floor of the maxillary sinus was elevated by the lesion. There was a external root resorption of the upper left canine, the 1st premolar, and the 2nd premolar. 3. On the computed tomograms, the osteolytic bony lesion expanded the cortical plate of the left maxilla and displaced the margin of the left maxillary sinus upwards. But the bony lesion was separated from the maxillary sinus by a bony septum. 4. Bone scintigram with /sup 99m/Tc demonstrated the increased uptake in the left maxilla. Sonograms in the neck area and chest P-A radiogram didn't show any abnormalities. 5. Histologically, the tumor islands infiltrating into the surrounding bone increased in alveolar pattern, composed of the malignant cells, and there was a necrosis in the center of the tumor islands.

Purpose : The study was aimed to detect the differences in the cell viability and the apoptosis induction after irradiation on normal and tumorigenic cells. Materials and Methods : The study. that was generated for two human normal cells(RHEK, HGF-l) and two human tumor cells(KB. HT-1080). was tested using MTT assay at 1 day and 3 day after irradiation and TUNEL assay under confocal laser scanning microscope at 1 day after irradiation. Single irradiation of 0.5. 1, 2. 4. and 8Gy were applied to the cells. The two fractions of 1. 2. 4. and 8Gy were separated with a 4-hour time interval. The irradiation was done with 5.38Gy/min dose rate using Cs-137 irradiator at room temperature. Results and Conclusions : 1. In 3-day group. the cell viability of HGF-1 cell was significantly decreased at 2. 4 and 8Gy irradiation, the cell viability of KB cell was significantly decreased at 8Gy irradiation and the cell viability of HT-I080 cell was significantly decreased at 4 and 8Gy irradiation. 2. There was significant difference between RHEK and KB cell line in the cell viability of 3-day group at 8Gy irradiation. There was significant difference between RHEK and HGF-1 cell line in the cell viability of 3-day group at 4 and 8Gy irradiation. 3. There was a significantly decreased cell viability in 3-day group than those in 1-day group at 2. 4 and 8Gy on HGF-1 cell. at 4 and 8Gy on HT-I080 cell. at 8Gy on KB cell. 4. We could detect DNA fragmented cells only on KB cell. Number of apoptotic cells of KB cell was significantly increased at 4 and 8Gy irradiation. However, there was no correlation between cell viability and apoptosis. 5. On all 4 cell lines, there were no differences between single and split irradiation method in cell viability and apoptosis.

공리적 설계를 활용한 고객만족형 설계VE 프로세스 개발

박인우,조규만,현창택,홍태훈,Park, In-Woo,Cho, Kyu-Man,Hyun, Chang-Taek,Hong, Tae-Hoon 한국건설관리학회 2009 건설관리 : 한국건설관리학회 학회지 Vol.4 No.2

국내 건설업체들은 비용절감과 성능향상을 통해 고객의 요구를 반영하고자하는 노력의 일환으로 설계단계의 가치공학(Value Engineering, 이하 VE)을 적극적으로 검토하고 있지만, 실제 VE 활동에서는 고객의 요구가 충분히 반영되지 않고 있으며, 고객의 요구를 측정하는 준비단계에서 기능분석, 아이디어 창출단계에 걸친 순차적인 진행 또한 미비한 실정이다. 본 연구에서는 고객의 요구기능이 VE 수행절차에 체계적으로 반영될 수 있도록, 공리적 설계이론(Axiomatic Design Theory)을 설계VE 프로세스에 도입하여 기존의 설계VE 프로세스를 보완하는 고객만족형 설계VE 프로세스를 제안하고자 한다. 고객만족형 설계VE 프로세스는 설계VE와 공리적 설계의 프로세스 및 특성상의 유사성을 바탕으로 두 이론의 연계방안을 정리하고, 기존의 설계VE 프로세스에 공리적 설계 프로세스를 추가.보완하는 형태로 완성한다. 이때 프로세스의 초기단계인 고객의 요구를 측정하고 정리하는 과정에서, 거주 후 평가(Post-occupancy Evaluation)를 활용하는 방안을 제시한다. 설계VE에 거주 후 평가를 활용하기 위해 평가 기준 및 방법을 설정하고, 이를 바탕으로 고객요구 측정 절차를 수립하여 그 절차에 따라 설문을 작성한다. 본 연구의 결과는 지금까지 국내 설계VE 활동에서 미진하였던 고객요구를 적극 반영하고, 기능과 아이디어의 관계에서 기능-아이디어-기능의 지그재그 창출 방법을 통해 기능-아이디어간의 연계를 명확하게 하여, 체계적이고 효율적인 VE활동을 기대할 수 있다. Value Engineering(VE) at design phase(so-called Design-VE) becomes quite a compulsory solution for better customer satisfaction, cost reduction, higher product performance, and, eventually, insured predominance in the competition. Unlike intended, however, the customer requirement on Design-VE has not been fully reflected in reality. Furthermore, the Design-VE occasionally does not progress in regular sequence; Preparation for measuring customer requirement - Function analysis - Idea creation. Therefore, this study suggests Axiomatic Design Theory to be adopted in Design-VE process expecting that the functions required by the customer could systematically reflected in VE process. Post-occupancy Evaluation(POE) is also represented as a method to measure and arrange the customer requirements. The customer satisfaction Design-VE process creates ideas defining functions in more detailed, to reflect the concrete user requirement. This approach helps function analysis and idea creation linked closely because function and idea are developed zigzag (i.e. function - idea - function...) in being decomposed into level down. The application of the process proposed by this study will be helpful to improve the customer requirement measurement and clarify a link between functions and ideas.

Objectives The purpose of this study is to analyze the clinical data of atopic dermatitis patients and to report the therapeutic effect of Jageum-Jung. Methods We conducted a retrospective study on the effects of treatment on atopic dermatitis patients who took Jageum-Jung from August 1, 2017 to December 20, 2017. The patients visited three times during the treatment period. The SCORAD Index score was measured and analyzed. Results Atopic dermatitis patients were 2 adults and 5 children. Both 2 adults were male (100%). Among the children, 1 child was a male (20%) and 4 children were females (80%). For adults, average age was 29.5 years, average weight was 72.75 kg, average height was 1.76 m and average BMI was $23.49kg/m^2$. For children, average age was 6.2 years, average weight was 23.92 kg, average height was 1.2 m and average BMI was $16.08kg/m^2$. The atopic dermatitis patients' average SCORAD Index score was 18.04 at first visit, 11.46 at second visit, and 7.64 at third visit. The scores lowered significantly after every visit. Conclusions The SCORAD Index in atopic dermatitis patients who took Jageum-Jung significantly decreased and it is expected that Jageum-Jung will be clinically effective in the treatment of atopic dermatitis.

박인우(Park In-Woo),권재기(Kwon Jae-Ki) 고려대학교 교육문제연구소 2007 敎育問題硏究 Vol.0 No.29

  부분별로 움직이던 행정을 효율적인 업무처리방식으로 한 번에 신속하게 처리할 수 있는 ERP는 1990년대 이후 국내 기업에 적극적으로 도입되었고, 대학에서도 혁신적인 통합정보시스템의 필요성이 부각되고 있다. 이에 본 연구는 성공적인 ERP 구축을 위하여 고려해야 할 대학특성이 무엇인지 밝힘으로써 각 대학특성에 따른 전략적인 ERP 도입과 ERP 구축 활성방안 마련, ERP 단일 패키지 개발 및 보급을 위한 정보를 제공하는 데 있다. 연구대상은 전국의 총 225개 대학(54.5%)이며, 12개 대학 특성 유형을 통하여 ERP 구축 유무, ERP 구축 필요성, ERP 구축 계획여부, ERP 만족도를 분류?분석하였고, ERP 구축 후 만족도에 영향을 미치는 대학특성 유형을 탐색하였다.<BR>  연구결과는 2가지 방법으로 분석되었다. 대학의 기반환경 특성 유형을 분류?분석하기 위하여 데이터마이닝 기법 중의 하나인 의사결정나무분석을 하였고, 탐색적인 과정으로 ERP 구축 후 만족도에 영향을 미치는 대학특성 유형을 알아보기 위해 중다회귀분석을 하였다.<BR>  연구결과는 첫째, ERP 구축에 영향을 미치는 결정적인 대학특성은 단일 ERP 패키지의 필요성 유무, 대학 규모, 정부의 패키지 사용의사 여부로 밝혀졌다. 둘째, ERP 미 구축 대학을 대상으로 의사 결정나무분석을 한 결과, ERP 구축 필요성에 영향을 미치는 결정적인 대학특성은 ERP 구축 계획 여부, 대학 규모, 대학 유형으로 밝혀졌다. 셋째, ERP를 구축한 대학을 대상으로 실시한 의사결정나무분석 결과, ERP 구축 후 만족도에 영향을 미치는 대학특성은 예산유형, 초기 소요된 예산, 설립 유형, 대학 규모, 정부 패키지 사용의사 여부로 밝혀졌다. 그리고 ERP 구축 후 만족도에 영향을 미치는 주요 요인은 초기 소요된 예산으로 나타났고, ERP 구축 시 초기 소요된 예산이 작으면 작을수록 ERP 만족도가 높은 것으로 나타났다.   The purpose of this study is to provide information with regard to (i) a strategic ERP introduction, (ii) an action plan for a successful and efficient ERP system construction, and (iii) a development & distribution of the standard ERP system package by analysing the specific character types in universities.<BR>  This study model covers 225 universities in Korea (approximately 54.5%). The university character types are classified and analyzed in light of whether or not the ERP system has been already in place, the system is necessary to construct and the construction plan is prepared. The character types are also analysed in terms of the satisfaction level of the ERP system based on the 12 characters of a university.<BR>  Two methods are employed to obtain the study results; (i) Weka ver 3.4 (a tool for Data Mining"s Decision Tree Analysis) in order to analyse the university character types and (ii) Multiple Regression to identify specific university character types that have an impact on the satisfaction level after ERP system is in place.<BR>  The former yield the following results. First, the critical Character types for ERP system construction are the necessity of standard ERP system package, a university scale and an intention to use the standard system. Second, the critical Character types for universities having no ERP system are the plan for ERP construction, a university scale and a university type. Third, the critical Character types affecting the satisfaction level after ERP system is constructed are the budget type, an initial budget, an establishment type, a university scale and an intention to use the standard ERP system package. Meanwhile, as a result of Multiple Regression, it is revealed that the key factor having influence on the satisfaction level subsequent to ERP system construction is the budget spent at initial stage. Moreover, the satisfaction level is analysed as being negatively correlated to the initial budget spent.
