뇨붕증 환자의 뇌하수체후엽의 고신호강도의 회복 : 배아종 환자의 추적검사 보도

Diabetes insipidus(DI) of central origin is a clinical syndrome resulting from low blood levels of antidiuretic hormone secreted from the posterior lobe of the pituitary gland, which is usually caused by lesions involving the hypothalamus-neurohypophyseal axis. MR imaging can reveal absence of the posterior pituitary bright signal(PPBS) in DI. The authors reviewed four patients with intracranial germinomas who had DI due to hypothalamus involvement. All patients before radiotherapy revealed absence of PPBS on MRI. Three cases recovered from DI after radiotherapy and showed reappearance of PPBS. Another one patient who continued DI didn't show signal change of the posterior pituitary gland. We speculated that the reappearance of PPBS is related to clinical improvement of DI.

With the development of low osmolar and nonionic contrast media in clinical practice, radiologists have enjoyed increased clinical application along with other advantages such as improvement of patient comfort and safety. Recently, radiologists have introduced many intravascular pharmacologic agents to improve diagnostic quality and patient safety. Shortly after the introduction of these agents, however, it was observed that a precipitate results when a certain pharmacologic agent is mixed with a low osmolar contrast media. These observations have prompted testing of several other drugs used for incompatability with contrast media. To verify these reports and to investigate other medications not previously tested, the authors analyzed mixtures of contrast agents and medications in vitro and observed them for visible precipitates after operating the highspeed centrifuge. The results were as follows: 1.The contrast media that produced incompatibilities with some pharmacologic agents were ioxaglate, diatrizote, and iothalamate in the order of frequency. 2.The contrast media that produced no precipitate were iopromide and ioxithalamate. 3. The pharmacologic agents that produced precipitate with some contrast media were papaverine, Benadry 1, Protamine, Cimetidine, Regitin, and Gentamicin. Therefore, we recommend that caution should be taken to recognize incompatibilities and avoid them when intravascular pharmacologic agents of any kind may be incompatible.
존 스튜어트 밀의 자유 개념에 관한 논의 : 개별성 개념을 중심으로
이호규 한국언론학회 2022 커뮤니케이션 이론 Vol.18 No.2
Most research regarding the concept of John Stuart Mill’s liberty have been carried out by the negative and positive liberty of Isaiah Berlin. However, Mill opposed the atomistic individual which was the underlying assumption of Berlin’s discussion on liberty. Mill argues that the theory of social contract is not valid to explain the characteristics of individual, rather individuals live together within the web of relationships. In this context, the research centering on the positive and negative liberty might be implausible from the assumptions. Most of discussions on liberty have dealt with the visible and physical oppression as well as those kinds of oppression‘s validity. However, Mill emphasizes that physical oppression greatly interfere with the liberty of individuals, but the most important thing to not be overlooked is the interference to affect the psychology as well as epistemology. From this standpoint, Mill suggests that individuals have to be an epistemological subject from the cultivation of individuality. For that being, Mill proposes the rational freedom to keep balance among the relationships which affect individuals’ psychology. Furthermore, he proposes reciprocal superiority for the mode of relationship. 존 스튜어트 밀의 자유 개념이 무엇인지를 파악하기 위해 많은 연구가 이사야 벌린의 소극적/적극적 자유 구분에 근거하여 분석하고 있다. 그러나 밀의 자유에 대한 논의를 개별성과 공리주의의 관계 틀에서 살펴본 결과 밀은 벌린이 제시한 소극적/적극적인 자유의 전제인 원자론적 개인을 부정하고 있다. 밀은 사회계약론이 주장하는 원자론적인 개인이 아니라 관계망에서 사는 개인을 상정하고 있다. 따라서 벌린의 구분에 근거한 밀의 자유에 대한 개념 논의는 전제부터 문제가 있다. 대부분의 자유에 대한 논의는 개인의 자유를 침해할 수 있는 실체가 있고 명백한 압력과 같은 물리적 권력의 정당성 여부에 대해 이루어지고 있다. 그러나 밀은 눈에 보이는 실체가 있는 압력도 문제가 되지만 나아가 개인의 심리/인식에 영향을 주는 사회 압력과 개인 자유의 관계에 초점을 두면서 인식의 주체로서의 개인을 위한 사회 분위기를 강조하고 있다.
大江 健三郞와 李淸俊 초기 소설 비교 연구 - 한・일 새로운 전후 세대의 세대감각과 현실인식 -
이호규 한국일본근대학회 2013 일본근대학연구 Vol.0 No.42
본 논문은 오에와 이청준의 초기 소설의 주제의식을 크게 두 가지로 나누어 살펴보고자 한다, 첫 번째는 각각 일본과 한국 의 새로운 전후세대로서 보이는 세대감각의 측면과 또 하나는 그러한 성찰을 바탕으로 한 현실비판의식이다. 일본의 경우 전후 문학의 주제가 새로이 변모하고 전후 소설가의 자기 변화와 새로운 작가들의 등장이 어우러지면서 새로 운 전후 소설이 나타나기 시작한 것은 1950년대 중반 이후였으며 한국 역시 한국 전쟁이 끝나고 십 년이 지난 후인 1960년 대 초였다. 오에와 이청준은 전후 문학에서 새로운 경향의 소설로 나아가는 세대의 대표 주자였다. 그들의 문학의 출발은 앞선 전후 세대와의 세대론적 차별성에 대한 인식, 그를 통한 자기 세대의 정체성 모색이었다. 자기 세대의 정체성 모색과 함께 그들 초기 소설의 주제는 망명자 혹은 비판적 아웃사이더로서의 현실비판인식이라 할 수 있다. 그것은 중심과 주변, 다수와 소수의 위계적 질서가 어떠한 장치를 통해 생산되고 수용되는지 그 양상에 대한 천착으 로 나타난다. 그것은 감금 혹은 배제로 나타나는 폐쇄성에 대한 고찰로 형상화된다. 오에와 이청준은 닫힌 사회의 권력체 제가 어떻게 종속적이며 순응적인 주체를 생산해내고 있는가를 주체 생산 매커니즘을 통해 비판한다. 다수적인(majeur) 통념을 통해 주체화를 사회적 질서 내지 지배 권력과 상응하는 방향으로 고정하려는, 기존 권력에 의해 내면화되고 습속화된 정체성에 대한 비판 속에 오에와 이청준은 새로운 주체화에 대한 가능성과 지향을 드러낸다. 오에와 이청준은 소외된 소수의 개인들이 공감대를 형성하고 새로운 인간관계를 지향하고 나아가 그를 통해 새로운 주체화를 모 색해나가는 과정을 통해 억압적이고 폐쇄적이며 획일적인 닫힌 사회의 극복의 당위성과 그 가능성을 보여주고 있다. This study intends to examine Oe and Lee Cheong-jun’s thematic consciousness of their initial novels dividing it largely into two parts. The first is the aspects of their sense of generation as a new post-war generation separately in Japan and Korea, and the second is their criticism on reality based on that introspection. In Japan, the time that the subjects of post-war literature changed newly and new post-war novels appeared as the novelists’ self-alteration and new authors’ emergence were harmonized is after the mid-1950’s. And in Korea, too, it was about the early 1960’s, that is, 10 years after the Korean War ended. Both Oe and Lee Cheong-jun were the leading authors in the generation proceeding from post-war literature to the novels with new trends. The start of their literature was recognizing the difference of generation from the previous post-war generation and also finding their own generation’s identity with it. Regarding the themes of their initial novels, not only they tried to find their own generation’s identity, but they did show criticism on reality as an exile or critical outsider. It is shown as inquiries on the aspects of what devices produced and accepted the hierarchical order of the center and circumference or majority and minority. And this is embodied as consideration on the closeness manifested as either confinement or exclusion. Oe and Lee Cheong-jun criticize how closed society’s power system produces subordinate and pliable subjects with the mechanism of production of subjects. Within the criticism on the identity internalized and conventionalized by the previous power that intended to fix subjectivation through majeur common notion towards the direction corresponding to the social order or ruling power, Oe and Lee Cheong-jun express the possibility and pursuit to new subjectivation. By forming the bond of sympathy among the individuals of alienated minority, pursuing new interpersonal relations, and furthermore, groping for new subjectivation through that, Oe and Lee Cheong-jun show the necessity and possibility of overcoming the oppressive and uniform, closed society.

It is often difficult to differentiate each pathologic entity among vrious spinal epidural masses on the radiologic bases. We retrospectively analyse radiologic findings of 67 cases of pathologically probven spinal epidural mass to find out any specific findingsof each epidural mass. RESULT : 1. Of 67 cases, metastasis, epicural abscess, neurogenic tuor and meningioma are most common. The others consist of epidural angioma, vertebral hemangioma, chondrosarcoma, fibrosarcoma, eosinopilic granuloma, lymphoma, lipoma and lymphoid hyperplasia. 2. Destruction of the adjacent bone was commonly associated with the epidural mass inmetastasis and epidural abscess. It was also noted in 2 cases of chondrosarcoma, 1 fibrosarcoma and 1 eosinophilic epidural abscess. It was also noted in 2 cases of chondrosarcoma, 1 fibrosarcoma and 1 eosinophilic granuloma. 3. Pressure erosion of adjacent bone was demonstrated in neurogenic tumor and meningioma. 4. Narrowing of intervertebral space was see in only 27% of epidural abscess. 5. The paraspinal tumor was associated in 67%of metastasis, 80% of epidural abscess, 75% of neurogenic tumor, 33% of meningioma. 6. The intradural tumor was associated in 50% of neurogenic tumor and 67% of meningioma. 7. On axial CT imagem, most of the epidural mass shows eccentric location with displacing dural sac to the opposite side. 8. The disease extent more than height of one verteral body was seen in 80% of epidural abscess, 58% of neurogenic tumor, 100% of epidural angioma.
