Purpose; Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.

The drag reduction by polymer additive is a well-known phenomenon and has been widely studied due to its high usefulness. In this study, in order to obtain the fundamental data on the drag reduction by polymer additive. we measured the friction factors in the polymer added turbulent flow through a circular pipe for Reynolds number ranging 10000-50000. As polymer additive, PEO (polyethylene oxide: molecular weight 4 x l0^(6)) was used. We also performed the experiments varying the concentration of PEO from 3 to 24 wppm to investigate the effect of the PEO concentration on the drag reduction. We observed more than 25% drag reduction under the above experimental conditions and the most effective drag reduction was found at 6 wppm (31% drag reduction).

전자우편 기반의 인터넷 EDI를 위한 수신 부인방지 및 메시지 반환 기능 설계 연구

Although S/MIME and OpenPGP are representative protocols used in transferring messages securely on internet environment, they have defects in the internet electronic data interchange (IEDI). In case of S/MIME, the implementation is most difficult due to the restricted usage of public key encryption library. And OpenPGP does not provide receiver non-repudiation and has weak extensibility under public key ring architecture for the authentication. In this paper, we propose a secure message transfer protocol by combining the protocols above in order that it may guarantee us receiver non-repudiation and return-of-content, which are necessary in E-mail based Internet EDI. By using this protocol, we can prevent the message-incurred resource waste in IEDI.

On the second year of king Hyo Jong, Lee Dynasty(A.D. 1651), the Yak Ryung Si(originated from Chinese Medicine) beganin Taegu. The market continued until the end of Japanese Occupation, when the controlled economy forced the market to be closed. The year 1957. the market began once again its function as the regular dealer of medicine. In this treatise, we try to report what material we examined and collected about the generally dealt-with crude drugs and its history in a statistic way. Our second aim is to standardize the crude drugs.

정순둘,장명선,이은진,송보가,김재민 이화여자대학교 젠더법학연구소 2021 이화젠더법학 Vol.13 No.2

본 연구는 노동시장에서 일할 수밖에 없는 여성노인의 다중차별 경험을 파악하여 이들의 노동권을 보호하고 차별을 해소하기 위한 방안을 마련하는데 목적이 있다. 이를 위해 노인집중 고용 업종에 종사하는 60세 이상 여성노인 14명을 대상으로 심층면접조사를 진행하였다. 본 연구 결과, 일할 수밖에 없는 여성노인들은 노동시장의 입직 단계에서부터 성별, 연령, 건강의 다중차별에 의한 상시적인 고용불안과 사회안전망에서의 배제를 경험하였다. 또한 일하는 조직의 불평등 지배체제 특성으로 일상화된 고용불안, 열악한 노동조건과 복지제도의 미비, 노인친화적이지 않은 노동 강도와 근무 제공, 노인 노동 평가 절하에 따른 조직 위계 문화와 관행, 과도한 노동 제공의 요구와 성희롱의 일상화, 조직 내에서 이해를 대변하는 데 어려움을 경험하는 것으로 나타났다. 본 연구 결과를 바탕으로 일할 수밖에 없는 여성노인의 다중차별을 해소하기 위한 법과 제도의 개선, 사회안전망 강화, 여성노인 노동자 이해대변단체 조직화 지원을 제언하였다. This study aims to (i) identify the experience of multiple discrimination among older women, who have no choice but to work in the labor market; (ii) protect their labor rights; and (iii) resolve discrimination. To conduct this study, we performed an in-depth interview survey with 14 older women aged 60 or older who are engaged in the elderly intensive employment sector. Under the result of this study, older women, who have no choice but to work, have experienced constant employment insecurity and exclusion from the social safety net due to multiple discrimination in gender, age, and health from the employment stage in the labor market. In addition, because of inequality organizations, they have experienced as follows: employment insecurity that became common, poor labor conditions and inadequate welfare systems, unfriendly labor intensity and provision of work, organizational hierarchical culture and practices due to devaluation of elderly labor, demand for excessive labor provision and sexual harassment routinely, and difficulties in representing understanding within the organization. Based on the results of this study, therefore, this study provides suggestions to resolve the multiple discrimination of older women, who have no choice but to work, including but no limited to, improve laws and systems, strengthen the social safety net, and organize support for the organization of interest groups for older women workers.

악성 갑상선 우연종의 임상상 및 초음파 소견의 진단적 가치

강한욱,김광원,이병완,강보현,김형훈,김범진,정재훈,민용기,이명식,이문규 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: 최근 갑상선 초음파 검사의 빈번한 시행으로 갑상선 우연종의 발견이 증가하고 있다. 이러한 갑상선 우연종은 임상적으로 어떻게 접근하고 치료를 해야 하는지 적지 않은 문제가 되고 있다. 본 연구에서는 직경 1.5㎝ 이하의 갑상선 우연종의 유병률, 입상적 특징 및 초음파 특성, 그리고 가장 효율적인 진단적 접근에 대해 알아 봤다. 방법: 1999년 1월부터 2000년 12월까지 삼성서울병원 내과 및 일반외과로 갑상선 결절을 주소로 내원한 1457명을 대상으로 후향적 연구를 시행하였다. 우연히 발견된 직경 1.5㎝ 이하의 갑상선 결절을 가지는 환자들에서 갑상선 결절의 촉지 유무, 갑상선 기능검사, 항갑상선 항체, 갑상선 초음파 및 미세침 흡인세포검사, 99m^Tc 갑상선 스켄, 수술 조직검사 및 병기를 검토하였다. 결과: 분석한 갑상선 결절 1475예 중 갑상선 우연종의 유병률은 13.4%(198예)였다. 갑상선 우연종에서 악성률은 28.8%(57예)으로 나왔다. 양성 및 악성 갑상선 우연종에서 나이, 성별, 갑상선 기능검사, 결절 크기에는 의미 있는 차이는 없었다. 갑상선 스켄은 갑상선 우연종의 감별에 적합하지 않았다. 갑상선 결절의 초음파 지표 점수만이 양성 및 악석 갑상선 우연종의 감별에서 초음파 지표 점수의 민감도는 88.9%, 특이도는 74.4%, 양성 예측률은 92.4%로 나왔고 진단적 정환도는 85.5%였다. 갑상선암으로 수술을 받은 50명중 stage 1은 34명, stage 2는 6명, stage 3은 10명으로 대부분의 악성 갑상선 우연종은 낮은 TNM 병기로 나타났으나, 상당수에서는 국소 침범의 소견을 보였다. TNM 병기의 3기 환자 전부는 45세 이상이였고, 주로 갑상선암의 피막 침범에 의한 것이었다. 임파절 전이는 6명의 환자에서 나왔다. 결론: 악성 갑상선 우연종은 비교적 흔히 접할 수 있는 질환이며 양성 우연종과는 임상적으로 구별이 안 된다. 악성 갑상선 우연종은 발견 당시 대부분 낮은 병기이나, 갑상선의 피막 침범 및 임파절 전이가 상당수에서 발견되었다. 갑상선 우연종의 초음파 소견은 향후의 진단 방향을 제시하는 중요한 길잡이가 될 수 있다. 초음파 지표 점수 2점 이상의 갑상선 우연종에서만 초음파 유도 미세침 흡입검사를 권장한다. Background: High-resolution ultrasonography has made the detection of asymptomatic small thyroid possible. Recent increases in the detection of incidentalomas have created a clinical dilemma on how to properly manage such incidental nodules. We investigated the prevalence, clinical and ultrasonographic characteristics, and optimal diagnostic approach toward incidentally detected benign and malignant thyroid nodules of less than 1.5㎝ in size. Methods: A retrospective review was undertaken on the 1,475 patients who had visited Samsung Medical Center, Seoul Korea between January 1999 and December 2000. The review consisted of a physical examination of the thyroid gland, thyroid function test, antithyroid antibodies, thyroid ultrasonography, fine-needle aspiration biopsy, pathology and TNA staging of the incidentally detected thyroid nodules of less than 1.5㎝ in size. Results: The prevalence of thyroid incidentalomas was 13.4% and the malignancy rate within them was 28.8%. There were no significant differences in age, sex, thyroid function test and size between the benign and malignant incidentalomas. Ultrasonographic characteristics showed meaningful diagnostic value for the detection of malignancy in incidentalomas. Most malignant incidentalomas were of a low stage. Conclusion: Occult thyroid cancers are fairly common finding. There are no clinical difference between benign and malignant thyroid nodules less than 1.5㎝; however, ultrasonographic findings can be used to decision of optimal management strategies (J Kor Soc Endocrinol 17:649∼656, 2002).
