  • Background: Brain metastasis from cholangiocarcinoma (CCA) is a rare but fatal event. To the best of our knowledge, only few cases have been reported. Herein, we report the incident rate and a first case series of brain metastases from CCA. Methods: Between January 2006 and December 2010 5,164 patients were treated at Srinagarind hospital, Khon Kaen University; of those, 8 patients developed brain metastasis. Here we reviewed clinical data and survival times. Results: The incident rate of brain metastases from CCA was 0.15%. The median age of the patients was 60 years. Tumor subtypes were intrahepatic in 6 and hilar in 2 patients. All suffered from symptoms related to brain metastasis. Three patients were treated with whole-brain radiation therapy (WBRT), one of whom also underwent surgery. The median survival after the diagnosis of brain metastasis was 9.5 weeks (1-28 weeks). The longest survival observed in a patient in RPA class I with two brain lesions and received WBRT. Conclusion: This is a first case series of brain metastases from CCA with the incident rate of 0.15%. It is rare and associated with short survival time.

  • Canine lymphoma (cL) is the most common hematopoietic cancer in dogs. Various determinants have been evaluated to find the predisposing factors in both human and canine lymphoma. Due to common risk factors and similar pathways, cL is considered a potential model for non-Hodgkin lymphoma (NHL) in humans. In this case-series study, major hospitals in Tehran consented to take part in this study and between the years of 2020-2022, provided us with 52 cL cases which were approved by the attended pathologist. We designed a questionnaire and collected information about the dogs and their owners. Most of the owners were women, young (younger than 50 years old), had at least diplomas and interestingly were housewives or househusbands. Male dogs with middle to old age (more than 6 years) were mostly referred. The most common characteristics were neutered, normal BCS, purebred, urban but not industrial residence, previous tobacco smoke exposure but no history of previous fungicide or pesticide exposure. Also, most of them did not have any previous autoimmune or immunosuppressive diseases. Presented characteristics should be considered risk determinants but to approve their validity, they should be further evaluated in epidemiological studies.

  • 최근 들어 해외 메이저급 애니메이션 회사들이 TV애니메이션을 플래쉬 프로그램으로 제작하기 시작하면서 국내 애니메이션 업계의 OEM 하청업체들은 뒤늦게 플래쉬 애니메이션의 제작 기술을 도입하기 시작했다. 하지만 아직까지 애니메이션 기술과 플래쉬 활용 기술을 모두 완벽하게 소화할 수 있는 인력은 얼마 되지 않는다. 또한 교육기관이나 학원에서도 모바일과 웹에 치중한 플래쉬 교육으로 인하여 전문 TV애니메이션을 제작할 수 있는 시스템이 갖추어지지 않고 있다. 분석 결과, 플래쉬 프로그램은 사용자의 편의성, 타 프로그램과의 호환성, 제작비의 절감효과 등의 장점으로 인하여 TV방영용 애니메이션을 제작하기에 매우 적합한 프로그램으로 결론 내린다. 현재 해외에서 제작하는 플래쉬 애니메이션의 제작 파이프라인을 도입, 체계화하여 매뉴얼을 구축하고 실무 제작에 적용시켜 국내 TV용 플래쉬 애니메이션의 질적 수준의 향상과 더불어 높은 경쟁력을 가진 애니메이션 제작에 도움이 되었으면 하는 바램이다.

  • Purpose: Weapon systems have the long life cycle unlike the consumer product. Thus, the reliability of weapon system is improved during the life cycle through the steady technical change. In this paper, we deal with the method of evaluating the reliability of weapon system with the field failure data. Methods: Especially, we present how to gather the field failure data and evaluate the reliability through the case of K-series weapon system. To evaluate reliability, the reliability growth model is used and the result is discussed. Results: It is steadily improved the reliability of K-series weapon system deployed from 2000 to 2004. The frequency of the failures that affect the mission is largely reduced and MTBMF(mean time between mission failure) is also improved. Conclusion: We can guess the trend of the reliability of weapon system with the field data through this study. Furthermore, it can be used to improve the reliability and make maintenance policy.

  • Objectives : It is the aim of this study to derive lurker studies evaluating the effectiveness of bee-venom phamacopuncture on malignant melanoma patients. We present a patient of malignant melanoma at right maxilla who survives over one year with stable disease (SD) by the treatment of Bee Venom Phamacopuncture (BVP). Methods : We followed the treatment and examination. We prescribed to the patient what to be taken 1.5cc BVP once a day. Picture series, Head series were followed-up and Neck computed tomography (CT) and positron emission tomography computed tomography (PET CT) were performed to evaluate the therapeutic efficacy. Results : The patient survives over one year and continued stable disease over 6 months. Picture series, Head series X-ray, neck CT and PET CT were shown no interval change. Conclusion : This case may give us the possibility that BVP offers potential benefits for patients with malignant melanoma.

  • This study was analysed influence of urban higher temperature in Busan about time series analysis of AWS data. The results are as follows. (1) The temperature of Busan show min $13.2^{\circ}C$ ~max $15.8^{\circ}C$ by 50 years, it is on the rise. (2) The seasonal adjustment series, summer appeared min $17.5^{\circ}C$ ~max $28.9^{\circ}C$ with primitive series similarly. The winter was min $-11.4^{\circ}C$ ~max $17.9^{\circ}C$, the minimum temperature was more lowly than primitive series and maximum temperature was more higher than primitive series. The results, seasonal adjustment series is guessed with influence difference urban structural element beside seasonal factor. (3) Regional analytical result, January appeared with range of min 28% ~max 196% of the seasonal factor and August appeared min 90% ~ max 106%. One of the case which is of 100% or more of the seasonal factor January 12nd~17th, August appears at the 15~17th.

  • Time series analysis results show the SVD is a candidate of on-line monitoring of welding penetration when the covariance matrix of a full penetration is used as a mapping function. As the reconstructed embedding vectors from the chaotic scalar time series are manipulated by the covariance matrix, the mapped tim series lie on a hyper-ellipsoid which the lengths of semi-axes are the squared eigenvalues of the covariance matrix in the case of full penetration. These visualize by two dimensional stroboscope views. The other cases like partial penetration, are different in the sense of sizes and shapes. Here we test two types of time series; the ion current and the X-ray. The ion current is better than the X-ray as an on-line monitoring signal, because the difference of the eigenvalue spectrum of the ion(between the pull penetration and partial penetration) is bigger than those of the X-ray.

  • This paper proposes a Taylor-series design method which reduces the height error of the tag when readers are arranged at the same height in 3-dimensional space. The proposed method consists of two steps. Firstly, the planar position is estimated by the Taylor-series method using the TDOA measurement. Next, the height is estimated from the estimated planar position. In order to show the validity of the proposed method, computer simulations were performed for the static case and linear trajectory of the tag. Results show that the proposed method gives convergent estimated position and better height estimate than the Taylor series method.

  • The aim of this study is to propose a systematic way of evaluating competing ELT textbook series. Three stages of evaluation procedures were employed: A sample of two sets of English textbook series for young learners were first analysed by five trained textbook evaluators using a checklist. Second, based on the results of analysis, evaluative discussion was carried out. Third, two independent evaluators conducted impressionistic evaluation on the series. The procedure employed in this materials evaluation process can be adapted in choosing series of textbooks. Since not many studies have dealt the evaluation of textbook series by multiple evaluators, the method presented in this study can be referred to and applied by materials evaluators in other contexts.

  • This study aims to monitor the displacement of the bridges using Stanford Method for Persistent Scatterers (StaMPS) time-series Persistent Scatterer Interferometric Synthetic Aperture Radar analysis. For case study bridges: Kimdaejung bridge and Deokyang bridge, we acquired 60 and 33 Cosmo-Skymed Synthetic Aperture Radar (SAR) data over the Mokpo region and Yeosu region, respectively from 2013 to 2019. With single-look interferograms, we estimated the long-term time-series displacements over the bridges. The time-series displacements were estimated as -8.8 mm/year and -1.34 mm/year at the mid-span over the selected bridges: Kimdaejung and Deokyang bridge, respectively. This time-series displacement provides reliable and high spatial resolution information to monitor the structural behavior of the bridge for preventing structural behaviors.
