Objective : This study was aimed to obtain epidemiological information of cancer patients treated with Oriental medicine. Methods :The medical records of 899 cancer patients treated at the East-West Cancer Center of Dunsan Oriental Hospital from January to December 2008 were analyzed. Careful investigations were done by categorizing these patients by their sex, origin, stage, treatment duration, conventional treatment type, etc. Results : 61.7% of the patients had stage IV tumor. 53.1% of patients visited Oriental hospital for combination treatment with conventional medicine. In the tumor origin, lung cancer showed the largest proportion (21.6%). Of the two genders, lung cancer was the most frequent cause (31%) in male patients, and breast cancer in females (21.2%). In inpatients, thyroid cancer resulted in the highest percentage (24.0%). Lung, colon, stomach cancer patients were mostly in stage III or IV. Thyroid cancer patients were mostly in stage I. Conclusions : This study presented the characteristics of cancer patients treated by Oriental medicine. Based on this study, further advanced study of Oriental medical cancer treatments is needed.

Objectives : The purpose of this study was to examine the changes in metabolic parameters and Positive and Negative Syndrome Scale (PANSS) scores of patients previously treated with atypical antipsychotic drugs other than paliperidone, after 8 weeks of treatment with paliperidone. Methods : Changes in body weight, body mass index, leptin, lipid levels, fasting glucose, and PANSS scores of patients who switched from other atypical antipsychotic drugs to paliperidone were measured after 8 weeks of treatment with paliperidone. We compared these results with those of patients who had not been treated with antipsychotic drugs for at least 2 weeks prior to treatment with paliperidone (antipsychotic drug-free patients). Results : The antipsychotic drug-free group (n = 9) did not show significant changes in metabolic parameters, but showed a significant improvement in total and subscale scores of PANSS. In the group that switched from other atypical antipsychotic drugs to paliperidone (n = 13), body weight, body mass index and fasting glucose level significantly increased, while total and subscale scores of PANSS significantly improved. Conclusions : Paliperidone treatment will benefit patients with schizophrenia who have been antipsychotic drug-free or who have had difficulty with other atypical antipsychotic drugs, with regard to their psychopathological state. However, if patients have been treated with other atypical antipsychotic drugs before switching to paliperidone, they could gain body weight or their fasting glucose level could increase over a short period because of a change in receptor number and sensitivity caused by the previously prescribed antipsychotic drugs, and hence, paliperidone should be prescribed with caution for these patients.

정태영,최홍식,Jeong, Tae-Young,Choi, Hong-Sik 대한한방내과학회 2004 大韓韓方內科學會誌 Vol.25 No.4

Recently a case of liver injury from ingestion of Taeyeumjowi-tang containing Ma-huang(Ephedra sinica stapf) arose. The patient, a 30 year-old woman, was diagnosed with asthenia and anorexia after 6 weeks of ingesting Taeyeumjowi-tang containing Ma-huang(Ephedra sinica stapf) as a treatment for her obesity. Tests showed elevated levels of serum transaminase(ALT 903 IU/L, AST 716 IU/L), alkaline phosphatase (229 IU/L), total bilirubin (1.4 mg/dl). Other possible causes of liver injury were excluded by laboratory test and medical history, so the liver injury was taken to be drug-induced. Saenggangeonbi-tang was administered. After 2 weeks of treatment with this medication, the clinical symptoms and liver function improved. This case is reported with a call for further accumulation of objective data on drug-induced liver injury, and to bring more attention to the relative levels of safety and toxicity of herbal medicines.

정태영(Jeong Tae-Young) 한국외국어교육학회 2005 Foreign languages education Vol.12 No.2

This study investigates the nature and the validity of the PhonePass SET-10 test designed to measure test-takers’ English oral proficiency using the automated computer technology. For this study, the data from 84 Korean college students were collected: students’ TEPS scores, PhonePass SET-10 results as well as the results from the survey developed to measure their attitudes toward the new format of English speaking test. Based on the analysis of the study, it is found out that there exists a positive correlation between the TEPS scores and the PhonePass SET-10 results of the participants, indicating that in fact the computer-based automated evaluating system can significantly contribute to assessing students’ English oral proficiency while the items and the purpose of the test administration are relatively limited. It is also reported that the participants of this study showed positive attitudes toward the PhonePass SET-10 with a hope that the newly developed speaking test will help them further their English study.

키보드컨트롤러의 하드웨어 취약점에 대한 대응 방안

정태영(Tae-Young Jeong),임강빈(Kang-Bin Yim) 한국정보보호학회 2008 정보보호학회논문지 Vol.18 No.4

본 논문은 문자열 기반 패스워드 인증에서 키보드 감시 문제를 유발하는 하드웨어 취약점에 대한 효과적인 대응방안을 제안한다. 악의적인 공격자가 해당 취약점을 이용하면 기존의 보안 소프트웨어가 실행되고 있는 상황에서도 키보드로부터 입력되는 사용자의 모든 문자열을 탈취할 수 있었으나 본 논문에서 제시하는 방안을 활용하면 공격자가 키보드 감시에 성공한다 하더라도 사용자의 입력 문자열을 온전히 탈취할 수 없다. 따라서 제안한 방안을 구현하여 적용하면 보다 안전한 인터넷 기반 금융거래가 가능해질 것으로 사료된다. This paper proposes an effective countermeasure to an intrinsic hardware vulnerability of the keyboard controller that causes sniffing problem on the password authentication system based on the keyboard input string. Through the vulnerability, some possible attacker is able to snoop whole the password string input from the keyboard even when any of the existing keyboard protection software is running. However, it will be impossible for attackers to gather the exact password strings if the proposed policy is applied to the authentication system though they can sniff the keyboard hardware protocol. It is expected that people can use secure Internet commerce after implementing and applying the proposed policy to the real environment.

정태영(Tae-Young Jeong),임강빈(Kang-Bin Yim) 대한전자공학회 2008 電子工學會論文誌-TC (Telecommunications) Vol.45 No.9

본 논문은 네트워크카메라 기반 영상감시시스템에서 발생하는 단위 네트워크 간 영상정보 공유 불가, 사용자 증가에 따른 대역폭 및 처리부하 증가, 네트워크 변경내역 지속적 모니터링 불가 등의 문제를 해결하기 위한 서버의 구조를 제안하고 이를 설계 및 구현하였다. 제안한 서버는 영상분배 기능을 제공함으로써 기존의 문제들을 해결하면서도 대용량 영상감시시스템을 위하여 다수의 네트워크카메라 및 다수의 사용자에 대한 관리와 서비스가 가능하도록 설계되었다. 구현한 영상분배서버를 실제의 영상감시시스템에 적용하여 실험한 결과 100여대의 네트워크카메라에 대한 접속을 유지하는 상황에서 수백여 사용자의 동시 접속을 처리하면서도 납득할 만한 서비스 품질을 유지함을 확인하였다. 본 논문의 영상분배서버를 활용하면 교통상황 정보 및 재난재해 감시 등의 대국민 서비스를 위한 대용량 영상감시시스템의 서비스 품질 향상에 기여할 것으로 기대된다. This paper proposes, designs and implements an architecture of a server involved with the network camera based video surveillance systems to solve common problems including lack of inter-network operability at the video information sharing, drawback of bandwidth and processing-overhead caused by increase of the number of users, and difficulty of continuous monitoring over changes of network configurations. The proposed server was designed to manage and service numerous network cameras and users as well as solving the existing problems by providing video distribution facility. Through the empirical study after applying the implemented server to a real video surveillance system we proved that the server can provide reasonable service quality while it processes several hundreds of simultaneous user connections under persisting more than one hundred connections to network cameras. We expect the developed video distribution server to enhance service quality of the large scale video surveillance systems for citizen-wide services such as traffic reporting informatics or natural calamities supporting.

This study examines the rustling sound characteristics of electrospun nanofiber web laminates according to layer structures. This study assesses mechanical properties and frictional sounds (such as SPL); in addition, Zwicker`s psychoacoustic parameters (such as Loudness (Z), Sharpness (Z), Roughness (Z), and Fluctuation strength (Z)) were calculated using the Sound Quality Program (ver.3.2, B&K, Denmark). The result determined how to control these characteristics and minimize rustling sounds. A total of 3 specimens` frictional sound (generated at 0.63 m/s) was recorded using a Simulator for Frictional Sound of Fabrics (Korea Patent No. 10-2008-0105524) and SPLs were analyzed with a Fast Fourier Transformation (FFT). The mechanical properties of fabrics were measured with a KES-FB system. The SPL value of the sound spectrum showed 6.84~58.47dB at 0~17,500Hz. The SPL value was 61.2dB for the 2-layer PU nanofiber web laminates layered on densely woven PET(C1) and was the highest at 65.1dB for the 3-layer PU nanofiber web laminates (C3). Based on SPSS 18.0, it was shown that there is a correlation between mechanical properties and psychoacoustic characteristics. Tensile properties (LT), weight (T), and bending properties (2HB) showed a high correlation with psychoacoustic characteristics. Tensile linearity (LT) with Loudness (Z) showed a negative correlation coefficient; however, weight (T) with Sharpness (Z) and Roughness (Z), and bending hysteresis (2HB) with Roughness (Z) indicated positive correlation coefficients, respectively.

Recently, several generative models have emerged and are being used in various industries. Among them, Cycle GAN is still used in various fields such as style transfer, medical care and autonomous driving. In this paper, we propose two methods to improve the performance of these Cycle GAN model. The ReLU activation function previously used in the generator was changed to Leaky ReLU. And a new loss function is proposed that considers the semantic level rather than focusing only on the pixel level through the VGG feature extractor. The proposed model showed quality improvement on the test set in the art domain, and it can be expected to be applied to other domains in the future to improve performance.
