To evaluate the sonographic features of invasive apocrine carcinoma (IAC) of the breast. This study included five pathologically proven cases of IAC, and their sonographic features were retrospectively analyzed according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon. All five lesions involved the left breast and were seen as irregularly shaped masses. All lesions, except one, had a parallel orientation to the chest wall. All five lesions showed noncircumscribed margins and heterogeneous echotexture; however, they showed various posterior features. One lesion had edema as an associated feature. Sonographic assessments were classified as BI-RADS category 4 in all five cases. Invasive apocrine carcinoma sonographic findings are difficult to differentiate from those of invasive ductal carcinoma of no special type.

Trichoblastic carcinoma is a rare malignant neoplasm of follicular germ cell origin; to the best of our knowledge, only six trichoblastic carcinomas arising in trichoblastomas have appeared on the literature. We recently experienced a trichoblastic carcinoma arising in a long standing trichoblastoma. A 68-year old woman came to the hospital with a chief complaint of an ulcerated nodule on her face. The nodule, 1.1×0.9 cm with an asymmetrical configuration, had been present and unchanged for more than 20 years, however, it grew suddenly with painful burning sensation. An excisional biopsy was performed and disclosed a deeply invasive, highgrade carcinoma, which consisted of cohesive epithelial cells arranged in irregular plump or germinative cell nests of various sizes. However, at the periphery of the tumor was a benign trichoblastoma surrounded by perifollicular sheath. We believe that the present case is a trichoblastic carcinoma developed via malignant transformation of pre-existing trichoblastoma.

대형오피스 빌딩 혼합공조(시스템에어컨+중앙공조)적용사례

서경진,정기호 대한설비공학회 2004 설비저널 Vol.33 No.8

국내 시스템에어컨 시장은 신도시 형성과 주상복합건물 및 중대형 아파트의 전실공조 필요성이 증대하고 빌딩 리노베이션 등 지속적인 건설시장 성장에 따라 수요가 급격히 증가해 왔으며, 중대형 공조설비를 대체할 차세대 공조시스템으로 시장에서 평가받고 있으며, 상업용 공조시장에서 차지하는 비율도 점차 증가하고 있다. 이런 결과 지난해 3,000∼3,500억 원대의 시장 규모는 올해 4,500∼5,000억 원대로 성장이 예상되면, 매년 30% 이상의 지속적인 시장확대가 예측되며, 도입초기에 주상복합, 아파트, 교단, 병원, 중소형 빌딩 등에 한정되었던 시장은 최근에는 중대형 빌딩용 멀티 에어컨의 수요가 꾸준히 늘어나고 있으며 선진시장인 일본에서 중앙공조 및 멀티에어컨의 장점만을 이용한 혼합 공조시스템이 90년대부터 적용되어져 왔으며, 현재에는 대형오피스 빌딩의 경우에도 공조방식이 시스템에어컨 및 혼합공조가 증가하는 추세이다.

다골성섬유형성이상에서 발생한 골육종: 증례보고

서경진 대한자기공명의과학회 2007 Investigative Magnetic Resonance Imaging Vol.11 No.1

섬유형성이상은 골모세포의 비정상적인 분화로 정상 골수와 해면골이 미숙골과 섬유성간질로 대치되는 유전이 되지 않는 골질환이다. 섬유형성이상은 다양한 영상소견을 보이며, 일반적으로 우연히 발견되며 정밀검사가 필요하지 않다. 그러나 섬유형성이상에서 병적골절의 합병증을 보일 수 있고 드물게 악성변이의 합병증을 가진다. 다골성섬유형성이상을 가진 44세 남자환자의 대퇴골에서 방사선소견상 골피질의 파괴와 자기공명영상에서 연부조직종괴를 가진 악성변이의 소견을 보였고, 수술로 절제된 조직학적 검사에서 연골아세포골육종으로 진단 받았다.

The radiological findings of various cervical spine fractures were analized on the basis of J. Harris classification. It appears to be important for the radiologist to be familiar with radiographic findings of cervical spine fractures, particularly those of unstable fractures which can result in serious medical problems if improperly handled in the department of radilogy. 68 cases of cervical spine fractures were analized. The results are as follows : 1. Stable and unstable fractures were about eual in incidence. 2. Anterior subluxation accounts for 43.4% of stable fractures, 19% of all fractures. 3. Bilateral interfacetal dislocation accounts for 51.1% of unstable fractures, 25% of all fractures. 5. About 80% of the patients is in third through fifth decade.

Costs and clinical outcomes of patients with diffuse large B-cell lymphoma in first remission: role of PET/CT surveillance

서경진,김기환,김률,변자민,김미소,박진현,김범석,김태민,김진수,최인실,허대석 대한내과학회 2019 The Korean Journal of Internal Medicine Vol.34 No.4

Background/Aims: The role of [18F]-f luorodeoxyglucose positron emission tomography- computed tomography (PET/CT) in patients with diffuse large B-cell lymphoma (DLBCL) in first remission is unclear. Methods: Medical costs within the first 3 years of treatment completion and clinical outcomes of 118 patients with DLBCL in first remission with and without surveillance PET/CT (PET/CT [+] group [n = 76] and PET/CT [–] group [n = 42], respectively) were retrospectively analyzed. Results: In a propensity matched cohort with adjustment for International Prognostic Index risk and relapse, the PET/CT (+) group was shown to have similar medical costs as the PET/CT (–) group. Relapse-free survival (RFS) and overall survival (OS) were comparable between the two groups (median RFS not reached [NR] for both groups, p = 0.133; median OS NR, p = 0.542). Among 76 patients with surveillance PET/CT, 31 (40.8%) had findings suggestive of recurrence and 16 of these (51.6%) were later confirmed to have recurrent disease. Fifteen patients (48.4%) were confirmed to not have recurrence after follow-up CT or PET/CT evaluation (n = 10) and biopsy (n = 4). None of the patients with negative PET/CT findings had disease recurrence. Sensitivity, specificity, positive predictive value, and negative predictive value of PET/CT for detection of recurrence were 1, 0.75, 0.52, and 1, respectively. Conclusions: Surveillance PET/CT resulted in similar clinical outcomes and medical costs compared to no surveillance PET/CT. Approximately half of patients with PET/CT findings of recurrence had no recurrence after follow-up imaging and biopsy, which would not have been carried out if PET/CT had not been performed in the first place.

With the growing usage of the networks, the world-wide Internet has become the main means to exchange data and carry out transactions. It has also become the main means to attack hosts. To solve the security problems which occur in the network such as Internet, we import software products of network security elements like an IDS (Intrusion Detection System) and a firewall. In this paper, we have designed and constructed the general simulation environment of network security model composed of multiple IDSes and a firewall which coordinate by CNP (Contract Net Protocol) for the effective detection of the intrusion. The CNP, the methodology for efficient integration of computer systems on heterogeneous environment such as distributed systems, is essentially a collection of agents, which cooperate to resolve a problem. Command console in the CNP is a manager who controls the execution of agents or a contractee, who performs intrusion detection. In the network security model, each model of simulation environment is hierarchically designed by DEVS(Discrete Event system Specification) formalism. The purpose of this simulation is that the application of rete pattern-matching algorithm speeds up the inference cycle phases of the intrusion detection expert system and we evaluate the characteristics and performance of CNP architecture with rete pattern-matching algorithm.

연조직종양의 새로운 WHO 분류를 중심으로: 지방세포종, 섬유모세포성/근육섬유모세포성종, 소위섬유조직구종, 평활근종, 혈관주위종과 근골격종에 대하여

연조직종양의 이해는 과거 10년 동안에 걸쳐 주요 변화와 더불어 실질적인 진보가 있었고, 이를 바탕으로 연조직종양의 새로운 분류가 WHO에 의해 2002년에 이루어졌다. 이 개정은 이전에 발표와 상당히 다른 내용의 접근을 하였고, 이 작업에 유전학과 분자생물학 그리고 임상분야의 전문가들이 참여하였다. 여기에서는 과거에 알고 있었거나 특성이 알려진 많은 종양을 포함하여 새로운 큰 변화나 작은 변화가 일어난 부분에 대해서 정리를 하였다. 이러한 내용을 연조직종양의 새로운 WHO 분류를 중심으로 지방세포종, 섬유모세포성/근육섬유모세포 성종과 소위섬유조직구종, 평활근종, 혈관주위종과 근골격종을 중심으로, 큰 변화와 작은 변화로 나누어서 설명하고 새롭게 소개되는 병명을 소개하고 정리하였다. 이 새로운 WHO의 연조직종양의 분류를 이해하여, 종양의 진단과 예후의 재현을 용이하게 하는 필수적인 지침으로 사용할 수 있을 것으로 생각된다. Soft tissue tumor classifications should be an important part of radiology, oncology and, for clinicians and pathologists, they provide diagnostic instruction and prognostic guidelines. In soft tissue tumor classification systems, the World Health Organization (WHO) classifications have become dominant, enabled by the timely publication of new 'blue books' which included detailed text and numerous good illustrations. The new WHO classification of soft tissue tumors was introduced in 2002. Because the classification represents a broad consensus concept, it has gained widespread acceptance around the globe. This article reviews the changes which were introduced the adipose tumors, fibroblastic/myofibroblastic tumors, so-called fibrohistiocytic tumors, smooth muscle tumors, pericytic tumors and skeletal muscle tumors which have been first recognized or properly classified during the past decade.
