Recent advances in imaging techniques, surgery and combination anti-cancer chemotherapy have brought high survial rates in osteosarcoma. To investigate the survival rate, local recurrence and complications in treatment, we analysed 25 osteosarcoma cases who had been treated with preoperative neo-adjuvant chemotherapy, surgery and post operative chemotherapy at Department of Orthopedic Surgery, Catholic University. From May 1988 to April 1995, 42 cases of stage IIB osteosarcoma were admitted in Department of Orthopedic surgery. Among them, 17 cases who didn't follow our treatment guidance were excluded in this study. The average age were 19 years. There were 21 males and 4 females. The involved sites were 4 humerus, 10 femur, 10 tibia and 1 talus. Eleven cases had received intra-arterial cisplatin and intravenous adriamycin chemotherapy, and 7 T-10 protocol and 7 intravenous ifosfamide, ADR, methotrexate, cisplatin. Among twenty-three cases were treated with limb salvage surgery, and 2 amputation. The average follow-up was 35 months(3-82). There were 14 cases of continuous disease free, 9 cases of died of desease, 1 case of alive with disease, and 1 case of no evidence of disease at final follow-up. There were three cases of local recurrence at 6,8 and 12 months after operation. The Estimated kaplan-Meier's 5 year survival rates for all, ADR-cisloatin group, T-10 protocol group, and ifosfamide regimen group were 66%, 73%, 44% and 72%, respectively.

As a result of the enlarging pool of unvaccinated children and young adults, there has been an increase in measles in our countries. In these situation, it has been reported that measles associated pneumoinia is easily complicated with fatal respiratory failure, espycially in immunocompromised patients. Herein we report the case of lethal measles pneumonia after allogenic hematopoietic stem cell transplantation in adults proven by autopsy. Recently, one case of measles was encountered in 39-year-old female patients after allogenic bone marrow transplanted case (chronic myelogenous leukemia), who progressed into interstitial pneumonia pattern, despite treatment including antibiotics, immunoglobulin. The patient died of giant cell pneumonia compatible with that of measles which was comfirmed in the section of necropsy lung specimen. (Korean J Infect Dis 33:301∼309, 2001)

목적: The aim of the study was to review the experience of fertility preservation (FP) program in a single center and to evaluate efficacy of FP referral program. 방법: From January 2013 to January 2016, the patients who have concern for their fertility that were referred to FP program were included. The age of patients at the time of discussing fertility preservation was under 40 years old. Total 103 patients who have undergone fertility preservation program in Severance hospital, Yonsei University College of Medicine were included. Statistical analyses were performed using chi-square test, Mann Whitney U test, and Kruscal-Wallis test according to the variables. 결과: Total 63 patients have undergone either embryo or oocyte cryopreservation, performing 82 controlled ovarian hyperstimulation cycles. Breast cancer patients composed the most: 15 patients (53.6%), 16 cycles of embryo; 22 patients (62.86%), 22 cycles of oocyte cryopreservation. Otherwise, patients diagnosed sarcoma, gastrointestinal, gynecological, and hematologic malignancy have been done the cryopreservation. Total 92 patients have received gonadotropin releasing hormone agonist for FP purpose. As similar as embryo/oocyte cryopreservation, patients with breast cancer composed the most: 46 patients (50%). The first 6 months follow up with serum anti-Mullerian hormone showed 0.23ng/dL (<0.08-13.41) in patients with breast cancer, 0.61ng/dL (<0.08-2.98) in patients with hematologic malignancy. The FP referral program between breast cancer clinic and infertility clinic was set since January 2015, and comparing the referral rate and FP rate between and after the FP program, significant increase was shown. However, referral and FP rate were similar in other cancers during the same time. 결론: The effective FP program between oncology department and infertility clinic seems to increase the rate of referral and participating FP program. Those who are expected to receive treatment that might affect fertility, should discuss about the FP options.

High-Resolution Millimeter-Wave Ground-Based SAR Imaging via Compressed Sensing

Jung, Sang-Hoon,Cho, Yong-Sun,Park, Rae-Seoung,Kim, Jong-Mann,Jung, Hyun-Kyo,Chung, Young-Seek IEEE 2018 IEEE transactions on magnetics Vol.54 No.3

<P>Compressed sensing (CS) is a technique which reconstructs an approximated full image using reduced samples. With the CS technique, the measurement time is reduced and high-resolution reconstructed data are obtained. On the other hand, the computational time is increased because the CS algorithm requires slightly more time than conventional reconstruction algorithms. Therefore, reducing the computational time is a critical issue. In this paper, an improved CS algorithm is proposed. The proposed algorithm is based on a greedy algorithm which solves CS problems using an iteration method. By reducing the number of iterations, the computational time of the proposed algorithm is reduced. The proposed CS algorithm is applied to a simple discrete Fourier transform problem and to millimeter-wave ground-based synthetic aperture radar imaging for verification.</P>

Optimal Design of Thinned Array Using a Hybrid Genetic Algorithm

Sang-Hoon Jung,Kang-In Lee,Hyun-Su Oh,Hyun-Kyo Jung,Hoongee Yang,Young-Seek Chung 한국전자파학회JEES 2021 Journal of Electromagnetic Engineering and Science Vol.21 No.4

In this paper, a hybrid genetic algorithm (GA) is proposed for thinning a two-dimensional planar array by combining the conventional GA with moving least squares (MLS). This enhances the convergence rate and the global search performance. The MLS method is used to estimate local interpolation functions from non-uniform sample data (the population and the value of the objective function in the GA), and to find new and better populations from the interpolated functions. By incorporating these improved populations into the next generation, the MLS-GA achieves improved search performance of the global optimum and a faster convergence rate compared to conventional GA alone. Moreover, a nonlinear chirp function is used for an efficient thinning design. To verify the proposed MLS-GA, it is applied to a test function and the results are compared to that of the GA. The algorithm is then applied to thin an array with a rectangular grid and circular boundary. The design objectives are to minimize the peak side-lobe level and gain loss while satisfying a given thinning coefficient and to compare the results with the GA.

Family meeting program(FMP) is to share information and discuss treatment between the patient, family members and health care professionals. In family centered society of Korea, when a patient is diagnosed as cancer, it is difficult to disclose the diagnosis directly to the patient. In this social setting, the primary purpose of our FMP focused on delivering the medical information to the patient himself or herself. The aim of this study is to improve the quality of FMP by analyzing the records of FMP. Patients who first admitted to oncology department for stage IV lung cancer before treatment and their family members were invited to FMPs. The house staff resident physician provided the current medical status of the patients, including diagnosis and stage of the cancer. The attending oncologist provided further treatment plan and prognosis. Data characterizing the meetings were collected by oncology specialized nurse using a data collection sheet. A total of 136 FMPs were conducted during an 18-month period. Prior to FMPs, family member and patients were aware of their diagnosis in 89.7% and 76.5% respectively. To further acquire information of their current medical status, patients actively participated in 102 of 136 meetings (75%). 13 patients refused the attention to the meeting. The family members of 18 patients concerned about the distress of the patients, therefore, they refused to invite the patients to the meetings. 3 patients were so poor to attend FMPs. Diagnosis, stage and primary goal of the treatment were informed in detail. However, the prognosis and life expectancy was discussed only in 93 meetings (68.4%). All patients and family members satisfied about the FMPs. 98 patients (95.1%) showed good comprehension during the meeting, and in 123 cases (90.4%), family members comprehended well. Although most of the patients participated the FMPs, a few patients did not join the meeting because their family members concerned about the distress of the patients. However, the patients participated the meeting actively wanted to know about their disease status, treatment plan, prognosis and life expectancy. The FMPs advanced the comprehension of the disease for the patients and their family members.

송과체부위종양의 가장 바람직한 치료방법은 수술적 요법이며, 과거의 shunting, 방사선 치료와 같은 보존적 요법은 이제 적당히 않다고 생각한다. 저자들은 1989년 6월부터 1994년 6월까지 본 병원에 입원하여 치료를 받았던 17예의 송과체부위종양 환자들을 대상으로 임상증상, 진단, 치료방법 및 그 결과를 보고하고자 한다. 남성에게 약간 많이 발생하였고, 평균연령은 다른 저자들의 보고마다 높은 약 32세 정도이었으며, 13세에서 51세까지의 연령분포도를 보였다. 14예에서 조직학적 확진이 가능하였으며(6예 ; occipital transtentorial approach, 5예 : infratentoria supracerebellar approach, 2예 : stereotaxic biopsy, 1예 : frontotemporal craniotomy for ectopic germinoma), 배세포종이 가장 많았다. 종양의 진행으로 인하여 3예에서 사망하였다. 송과체부위에서 발견되는 종양이 조직학적으로 다양하여 이에 따른 각기 다른 치료방법을 요하고, 또한 미세현미경적수술 및 뇌정위적수술 수기가 향상되어 사망률 및 이환율이 낮아졌으므로 생검진단은 반드시 시행되어야한다. TThe authors think that the more desirable treatment for pineal region tumors is definitive surgery with a histological diagnosis and that a conservative approach consisting of shunting and radiation therapy no longer seems to be appropriate. We report the result of a retrospective review of the presentation. treatment, and outcome of the seventeen patients treated between June. 1989 and June, 1994. Nine patients were males and eight patients were females. and the age ranged from 13 to 51 years (mean age about 32 years old). Histological verification was available in fourteen tumors ; six by an occipital transtentorial and five by an infratentonal supracerebellar approach and two by a stereotaxic biopsy and one by a frontotemporal crniotomy for ectopic germinoma. Germinomas were the most common type. Three of the seventeen patients died of tumor progression. Because the treat variety of tumor found in the pineal region must be treated in different way and because improved microsurgical and stereotaxic surgical techniques have made mortality and morbidity rates acceptably low, a biopsy diagnosis should be obtained.
