Objective: To evaluate the safety and feasibility of single-port access laparoscopically assisted vaginal hysterectomy (SPA-LAVH) using conventional laparoscopic instruments compared to multi-port access laparoscopically assisted vaginal hysterectomy (MPA-LAVH). Methods: We reviewed the medical records of 220 patients with uterine leiomyoma or adenomyosis who underwent 110 SPA-LAVH and 110 MPA-LAVH in Incheon St. Mary`s Hospital between April 2007 and November 2009. We performed SPA-LAVH with conventional rigid straight laparoscopic instruments in all cases. We also performed a new vaginal cuff closure method, Kim`s Vaginal Vault Suspension Method, named after the operator (Kim, YW) in both SPA-LAVH and MPA-LAVH. Results: There was no significant difference in patients` age, operating time, uterine weight, hemoglobin change, frequency of blood transfusion, and incidence of postoperative fever between the two groups. The patients` mean age was 46.1±7.0 years (SPA-LAVH) and 45.5±6.3 years (MPA-LAVH). The mean operating time was 87.2±21.0 minutes (SPA-LAVH) and 83.3±20.3 minutes (MPA-LAVH). The mean uterine weight was 261.4±139.7 g (SPA-LAVH) and 257.8±132.9 g (MPA-LAVH). The mean hemoglobin change was 1.1±0.7 g/dL (SPA-LAVH) and 1.2±0.6 g/dL (MPA-LAVH). Neither bowel injury nor urinary tract injury occurred during the operation in the two groups. One of the SPA-LAVH and one of the MPA-LAVH cases were converted to abdominal total hysterectomy. The mean hospital stay time was shorter with SPA-LAVH (2.6±0.6 days [SPA-LAVH] and 3.3±0.7 days [MPA-LAVH], P<0.05). Conclusion: SPA-LAVH using conventional rigid straight laparoscopic instruments can be offered as a safe and feasible alternative to MPA-LAVH.

실리콘 기판 위의 나선형 인덕터에 대한 SPICE 모델

김영석,박종욱 충북대학교 컴퓨터 정보통신 연구소 2000 컴퓨터정보통신연구 Vol.8 No.1

회로설계 엔지니어들이 쉽게 RF IC 설계에 사용할 수 있는 나선형 인덕터의 SPICE 모델을 개발하였다. 이 모델은 나선형 인덕터의 등가회로 소자 값들을 SPICE의 user-defined function 및 subcircuit 기능을 이용하여, 레이아웃 변수, 공정 변수, 실리콘 기판 변수로부터 정의하였다. 특히 인덕턴스는 임의의 회전에 대한 인덕턴스 Li 및 임의의 두 회전에 대한 상호 인덕턴스 Mij를 subcircuit으로 정의하여 전체 인덕턴스 값을 계산하였다. 모델의 정확성을 검증하기 위하여 CMOS 0.8㎛ 공정으로 제작된 나선형 인덕터의 측정 s- 파라미터, 총 인덕턴스 및 quality-factor 결과를 시뮬레이션 데이터와 비교한 결과 일치함을 확인하였다. 본 논문에서 제시된 SPICE를 이용한 나선형 인덕턴스 모델은 scalable하며, 실리콘 기판의 영향 등을 포함하기 때문에 레이아웃 최저고하에 쉽게 사용할 수 있는 장점을 가진다. The SPICE model of the spiral inductor on silicon substrate which can be easily used for the RF IC design has been developed. In this proposed model the equivalent circuit elements of the spiral inductor are defined by the layout and process parameters using the user-defined function and subcircuit of the SPICE. The total inductance is calculated using the subcircuit Li for the arbitrary turn I and the Mij for two arbitrary turns. The model was verified by comparing the simulated data with the measured s-parameters, total inductance, and quality factor of the spiral inductor fabricated by the CMOS 0.8㎛ process. The proposed SPICE model of the spiral inductor is scalable and includes the effects of the silicon substrate.

디지털 매체 혹은 가상현실에서 이미지의 문제

김성민,박영욱 한국철학사상연구회 2004 시대와 철학 Vol.15 No.1

디지털 기술 혹은 매체는 단순힌 새로운 기술의 출현만을 의미하는 것이 아니다. 그것은 인간의 지각과 상호 의사소통에서 새로운 변화를 의미한다. 이러한 근본적 변화의 성격 때문에 디지털 매체에 대한 철학적 고찰이 필요한 것이다. 이 논문은 디지털 이미지와 가상현실의 문제에 초점을 맞추어 디지털 매체가 어떤 인식론상의 근본적인 변화를 가지고 왔는지에 대해 철학적으로 논구할 것이다. 이에 대한 철학적 논의는 크게 세 가지 쟁점으로 압축될 수 있다. 먼저, 디지털 매체가 낳은 가상현실의 문제이다. 가상현실은 한편으로는 가상적이기도 하지만 또 한편으로는 현실적이기도 하다는 역설적 표현을 담고 있다. 따라서 가상현실의 이러한 역설이 어떻게 해명되어야 하며 그러한 역설이 실제로 디지털 매체 속에서 어떤 방식으로 진행되며, 인간의 지각방식이나 의사소통 체계에 어떤 영향을 끼치는지에 대한 논의가 진행된다. 둘째, 디지털 이미지의 비물질성이라는 특성에 관한 것이다. 주로이미지를 통해서 주어지는 디지털 매체의 정보형태는 '지금'과 '여기'라는 시공간적 규정을 벗어나있다는 특징을 지닌다. 이를 흔히 디지털이미지의 비물질성이라는 특성으로 요약할 수 있다. 이러한 디지털 이미지의 특성은 코드화되는 순간 이미 변형을 전제하므로 그것에 의해서 전달되는 의사소통의 체계 또한 일방적인 것이 아니다. 셋째, 디지털 이미지에 의한 가상현실이 지금까지 현실에 구속된 지각의 세계를 벗어나 새로운 세계를 창출하는가에 대한 물음이다. 여기서는 레비와 비릴리오의 전망을 대비시킴으로써 그 쟁점을 간단하게 살펴보는 것에 논의를 제약한다. The advent of digital technology or media does not simply mean the emergence of a new technology. Quoting Mcluhan, the appearance of a new medium means the alterations in the way of human perceptions and mutual communications. These kinds of the radical changes give a space for the philosophical penetration into the new technology. In this paper I'm just trying to give a rough but philosophical consideration on some issues about digital images, nonetheless eventually leaving the problems unsolved rather than settle down the issues. Considering the current situation of the new media in its initial stage, we can find a good excuse for the delay of a clear conclusion about these problems. Deleuze's saying "philosophy is not solving a problem but posing a problem" can have no more suitable place than in this case. The philosophical problems which are caused by the digital technology are summarized as following three. The first problem is related with the nature of the 'Virtual Reality'. Considered in its literal meaning, the word 'Virtual Reality' itself is contradictory. For the two terms 'virtual' and 'reality' which are all parts of the word are basically irreconcilable with each other. From this contradiction does the question follow inevitably. "Is a Virtual Real world a fictional world or another real world?" Secondly, It's the problem related with the 'immateriality of the digital image'. The fact that the digital image is beyond 'now' and 'here' can be summarized as it's 'immateriality'. This means that digital images (which are the main forms of information used by the digital media) have an unlimited possibility to be transformed. It can open a new horizon for a new type of human perception. Thirdly, is the new dimension produced by the digital media a so-called new world that leads us to the new world of perception unlike our everyday perception? This article deals with the two rival thinkers about this problem, Pierre Levy and Paul Virilio.

Multiple myeloma is a disease caused by neoplastic plasma cells that synthesize abnormal amouts of immunoglobulin or immunoglobulin fragments. Light chain myeloma are regarded as a separate category characterized by a more malignant clinical course. Light chain myelomas are said to grow fastest of all and are associated with more osteolytic lesions, more hypercalcemia, and a higher incidence of renal failure and amyloidsis than either the IgG, IgA varienties The authors experienced a case of patients with λ-light chain myeloma. A 43-year-old male patient admitted to our hospital with the chief complaint of both rib and lower back pain. The radiologic findings showed multiple pathologic fracture in ribs. osteolytic lesions in 2nd, 3rd cervical spineimmuture plasma cells. Serum electrophoresis showed normal finding. Urine electrophoresis evealed an M-spike. Urine immunoelectrophoress demonstrated λ-monoclonal protein. With the cycle of melphalan, prednisone and α-interferon chemotherapy improved of pain was observed. So we reported the case with brief review of previous literature.

The fungal sinusitis is relatively rare and mainly develops in immunocompromised hosts, but is sporadically appears in the immunocompetent patients, where its incidence tends to be increasing. Because the clinical features of this disease are similar to those of chronic suppurative sinusitis, this entity may be overlooked. We analysed thirteen fungal sinusitis from January 1997 through December 1999 based on clinical features, laboratory characteristics and operative findings. The results are as follows. 1)Fungal sinusitis occurred 3.3 times as frequently in female patients as in male patients and the peak age groups are 4th and 5th decades. 2) The time intervals between the onset of symptoms and the first hospital visit were as follows: 5 cases within 3 months, 1 case between 4 and 6 months, 3 cases between 7 and 12 months, and 4 cases over 1 year. 3) The chief complaints were nasal obstruction, postnasal drip, rhinorrhea, cheek pain, headache, ocular pain, sneezing. 4) The characteristic computerized tomographic findings were hyperattenuated lesions in the maxillary sinus and in the nasal cavity near the natural ostium. 5) The most common pathogen was Aspergillus(92.3%) 6) We performed Caldwell-Luc's operation only in 4 cases, Caldwell-Luc's operation with intranasal ethmoidectomy in 3 cases, Caldwell-Luc's operation with endoscopic sinus surgery in 3 cases and endoscopic sinus sugery only in 3 cases. 7) Most of the gross specimens revealed a fungus ball containing a black-brown necrotic debris or caseous material.

Malignant histiocytosis, originally described in 1939 as histiocytic medullary reticulosis by Scott and Robb-Smith, is a rare histiocytic proliferative disorder that often shows an acute onset and used to progress to death within a few months. This disorder characterized clinically by fever, generalized weakness, lymphadenopathy and hepatosplenomegaly, and shows a variable range of pancytopenia. Extranodal involvement is common, with an incidence ranging from 50% to as high as 90%, skin involves8ment was noted in 10% to 15%. Typical skin lesions were mainly founded in extremity. i.e. erythematous papule and nodule occasionally become to necrosis and ulceration. We experienced one case of malignant histiocytosis in a 46-years-old female. The major clinical findings are fever, malaise, hepatosplenomegaly and erythematous skin lesion. In the laboratory study, pancytopenia is noted on the peripheral blood. And also aggregation of many atypical histiocytes were shown on skin and bone marrow biopsy. So we reported one related case with malignant histiocytosis as well as reviewing literature .
