Objective: This study was prepared to figure out a certain dimension and morphology of the condyle at the central, medial and lateral aspects on MR images of asymptomatic volunteers, which could be comparable with those of the TMD patients' condyle. Materials: Sixty TMJs from 30 asymptomatic volunteers(15 male, 15 female) who had no clinical symptoms and no disc displacement on sagital and coronal view of MRI were served as normal. Method: MR images were taken from the asymptomatic volunteers and the dimension of the anteroposterior length, mediolateral width, height, convexities were measured through the images on the sagittal and coronal sections of mandibular condyle. Then, these data were collected and analyzed. Result: The mean value of anteroposterior length was $8.00{\pm}1.21mm$ at central section and mediolateral length was $21.40{\pm}2.32mm$ on coronal view. The anterior condylar length at medial side was the shortest and the convexity of anterior slop at the lateral side was proved to be the flattest among 3 sections. There were little dimensional and morphological differences at sagittal sections, but the mediolateral width of condyle at coronal section was significantly different between male and female. Conclusion: In sagittal sections, the anterior condyle length was shortest at medial side and the convexity of anterior slop was flattest at lateral side, and there were little dimensional and morphologic differences between male and female. In coronal section, male's condyle was more wider and flatter than female's.

A sample of soil humic acid (HA) was divided by ultrafiltration (UF) into five fractions of different molecular size (UF₁: > 300, UF₂: 100~300, UF₃: 30~100, UF₄: 10~30, UF₅: 1~10 kilodaltons). Apparent average molecular weight (M_w) of the HA fractions were measured using high performance size exclusion chromatography (HPSEC), and the chemical and structural properties of the five HA fractions were characterized by elemental compositions (H/C, O/C and w ((2O + 3NH)/ C)) and ultraviolet-visible absorption ratios (SUVA, A_4/6). The organic carbon normalized-sorption coefficients (Koc) for the binding of phenanthrene to the HA fractions were determined by fluorescence quenching and relationship between the sorption coefficients and structural characteristics of the HA fractions were investigated. The elemental analysis and UV-vis spectral data indicated that the HA fractions with higher molecular weights have grater aliphatic character and lower contents of oxygen, while the HA fractions with lower molecular size have greater aromatic character and molecular polarity that correspond to greater SUVA and internal oxidation values (w). The log Koc values (L/kg C) were gradual increased from 4.45 for UF₅ to 4.87 for UF1. The correlation study between the structural descriptors of the HA fractions and log Koc values of phenanthrene show that the magnitude of Koc values positively correlated with $M_w$ and H/C, while negatively correlated with the independent descriptors of the O/C, w, SUVA and A_4/6.

Objective: In many TMD cases, deformed and reduced condyle heads were frequently observed. This study was prepared to compare the dimensions between normal and symptomatic condyles, using MR images. Materials: One hundred and twenty one patients with clinical signs and MRI-confirmed diagnosis of disc displacement were selected for this study. Thirty eight TMJs from nineteen asymptomatic volunteers who had no clinical symptoms and no disc displacement on sagittal and coronal view of MRI, were served as normal. Methods: Symptomatic condyles were classified according to the severity of the anterior disc displacement. The amount of anterior disc displacement was evaluated at sagittal section, and they were classified into 4 groups as normal(N), little(G0), mild(G1), moderate(G2) and severe displacement(G3). The dimentions of condyle were measured at the 200% magnified view, by digitizing program. All dimensions were compared among each groups on the central section of sagittal and coronal views, and the statistical analysis was performed. Results: The mean value of anteroposterior length of normal condyle was $0.79{\pm}0.13cm$ at sagittal section and mediolateral length was $2.12{\pm}0.22cm$ on coronal section. The mean value of anteroposterior length of symptomatic condyle was $0.67{\pm}0.16cm$ at sagittal section and mediolateral length was $1.97{\pm}0.28cm$ on coronal section. Conclusions: The size of symptomatic condyle was smaller than normal TMJ. The size of condyle was decreased as the amount of the disc displacement was increased. The dimensional change was found on the anterior articular surface of condyle at the mild or moderate disc displacement. And at the case of severe disc displacement, dimensional change was found on the superior articular surface.

건설 산업은 다양한 프로젝트를 수행하는 수주중심의 산업적 특성상 정형화된 프로세스로 구축하여 운영하는 것이 매우 어렵다. 이에 건설기업의 동적인 업무 변화 특성 수용과 업무개선을 동시에 만족시킬 수 있는 BPM(Business Process Management)의 도입이 대형 건설업체를 중심으로 이루어지고 있는 상황이다. BPM의 특성과 기업의 고유 전략이 상이하기 때문에 일괄적인 적용은 어렵다. 이에 건설 산업의 특성과 프로세스를 이해하고 기업이 추구하는 비전과 목표에 부합하는 업무 프로세스를 우선 선정하여 적용하는 것이 필요하다. 본 연구에서는 기존 연구 고찰을 통하여 BPM 우선 적용 대상 프로세스 선정방안의 필요성을 제시하고, 건설기업 업무 프로세스 분석을 통해서 건설기업의 BPA를 구축하였다. 국내 건설기업의 전략목표 우선순위 파악을 통하여 높은 우선순위를 가지는 것으로 도출된 수익성과 성장성의 관점에서 핵심 업무 프로세스를 도출하였다. 또한 BPM 적용대상 프로세스 평가 기준을 6가지로 제시하여 이를 바탕으로 핵심 업무 프로세스를 평가하여 BPM 우선 적용 대상 프로세스를 도출하였다. Construction companies are fulfilled in according to project, and it is difficult to execute the standardized process in various construction projects. Thus many construction companies is adopting BPM(Business Process Management) that meet business process change and business improvement. However, it is difficult to apply BPM in a lump because of difference of BPM characteristics and company's strategies. For this reason, it is desirable to select business process based on company's priority. This study indicated need of method for selecting business process through studying current researches, and made BPA for construction company by analyzing business process in construction company. Moreover, this study indicated core business process from a point of profitability and growth view through grasping strategic goal priority. And also, it proposed criteria for process evaluation for BPM adoption, evaluated core business process, and indicated prior business process for BPM adoption.

바울의 예루살렘 여행기에 나타난 ‘비극적 역사’ 문체

이두희(Doo-Hee Lee) 한국신학정보연구원 2011 Canon&Culture Vol.5 No.1

그레꼬-로마 역사 기술 전통을 살펴보면, 헤로토토스와 투키디데스를 비롯한 거의 대부분의 역사가들이 비극에 속하는 문학적 장치들을 활용하여 독자들의 읽는 재미를 더하고, 의미의 효과적인 전달을 꾀하곤 하였는데, 이처럼 역사 기록에 있어서 비극에 속하는 문학적 장치를 활용하여 역사를 기록하는 역사 기술 문체를 가리켜 폴뤼비오스는 ‘비극적 역사’라고 명명하였다. ‘비극적 역사’ 문체의 특징으로는 1) 전형적인 비극적 이야기 패턴의 하나인 ‘koros(포만)-hybris(오만)-ate(미망/파멸)’ 도식, 2) 두 가지 어려운 선택지 중에서 어느 하나의 선택을 강요당하는 경우, 3) ‘피할 수 없는 운명’에 대한 인식과 ‘비극적 아이러니’를 통한 ‘연민과 공포’의 유발, 4) 생생한 세부 묘사(enargeia), 5) 때 늦은 깨달음(ophsimathia) 패턴의 활용 등을 들 수 있다. 본 논문에서는 그 중에서 특히 ‘두 가지 어려운 선택지 중에서 어느 하나의 선택’을 해야만 하는 상황과 ‘생생한 묘사’를 통한 ‘감정에의 호소’라는 특징이 사도행전 20:1-21:16에 해당하는 바울의 예루살렘 여행기 부분에서 발견됨을 살펴봄으로써, 누가-행전의 저자가 ‘비극적 역사’ 문체를 활용하여, 독자들과의 소통을 극대화하고 있음을 보여주고자 한다. 이러한 필자의 주장은 그동안 많은 학자들이 바울의 예루살렘 여행기에 나타나고 있는 특징으로 관찰은 했으면서도, 그 유래와 기능에 대해 효과적으로 설명하지 못했던 두 가지 문제를 설명하는 새로운 제안이 될 것이다. 그 중 하나는 사도행전 20:36-38에 나오는 바울과 에베소 장로들의 이별 장면 묘사로서, 많은 학자들이 그 묘사에 있어서 예외적인 감정적 묘사에 주목하였으나, 그 효과와 유래에 대해 적절한 설명을 하지 못해왔다는 것이고, 또 다른 문제는 왜 사도행전에 묘사된 바울의 예루살렘 여행기에서는 바울의 여행 목적이 분명하게 ‘구제금의 전달’과 연결된 것으로 밝혀지고 있지 않은가 하는 것이다. 이 두 가지 문제는 효과적인 의사소통을 위해 누가가 도입한 ‘비극적 역사’ 문체와의 관련 하에서보다 잘 설명될 수 있다는 것이 필자의 주장이다. In the tradition of Greco-Roman historiography, most historians, including Herodotus and Thucydides, have employed literary techniques used in Attic Tragedy so that they may maximize the effects of communication, thereby entertaining readers. In his Histories, Polybius called it ‘tragic history.’ Some of characteristics of ‘tragic history’ are as follows: 1) koros(satiety/surfeit)-hybris-ate(infatuation/ruin) pattern, 2) a dilemma between two difficult options, 3) evocation of ‘fear and pity’ by ‘tragic irony’ and recognition of inevitable fate, 4) vivid portrayal(enargeia), and 5) late-learning(ophsimathia). In this paper, I attempt to demonstrate that we can find out two of those characteristics of ‘tragic history’ style in the description of Paul’s Journey to Jerusalem(Acts 20:1-21:16): vivid portrayal and a dilemma between two legitimate choices. Regarding the pericope of Paul’s journey to Jerusalem, there have been two enigmatic issues which were not easy to explain out: 1) an extra-ordinary emphasis on emotions in the portrayal of Paul’s parting from Ephesian elders and 2) why Luke did not mention explicitly ‘delivery of collections for the poor,’ which is specified in Paul’s letters(Rom. 15:25-26; 1 Cor. 16:1-4), as the purpose of visit to Jerusalem. Many scholars have recognized those peculiar characteristics, and have tried to answer them. But no explanation was definitively satisfactory. This study suggests a plausible way to answer those two questions that have long been recognized but unsatisfactorily explained. In my view, those characteristics are related to Luke’s intentional employment of ‘tragic history’ style to enhance the effects of communication with readers. By employing ‘tragic history’ style, in other words, making readers emotionally engage in the message Luke tried to communicate, Luke enhanced the effects of communication. At the same time, in doing so, Luke made sure that the readers listen to his message that they should follow Paul’s way in making decisions.

Amyopathic dermatomyositis is defined by characteristic cutaneous manifestation of dermatomyositis without evidence of muscle involvement. There is no clinical difference between dermatomyositis and amyopathic dermatomyositis. Pulmonary involvement of dermatomyositis is so frequent than aggressive dianostic and therapeutic approach is needed. Early steroid or immunosuppresive treatment in pulmonary involvement of dermatomyositis gets better prognosis. Intravenous immunoglobulin treatment is an effective and safe alternative when the steroid or immunosuppresive treatment is ineffective or intolerable. We are reporting a case of amyopathic dermatomyositis with interstitial lung disease. This patient was improved with intravenous immunoglobulin treatment.
