Illegal and harmful contents on the Internet has been an issue and been increased in Korea. They are often posted on the billboard and website of small enterprise and government office. Those illegal and harmful contents can relate to crime and suspicious activity, so, we need a detection system. However, to date the detection itself has been conducted manually by a person. In this paper, we develop an automated URL detection scheme for detecting a drug trafficking by using Google. This system works by analyzing the frequently used keywords in a drug trafficking and generate a keyword dictionary to store words for future search. The suspected drug trafficking URL are automatically collected based on the keyword dictionary by using Google search engine. The suspicious URL can be detected by classifying and numbering each domain from the collection of the suspected URL. This proposed automated URL detection can be an effective solution for detecting a drug trafficking, also reducing time and effort consumed by human-based URL detection.

Purpose: Oral naloxone is combined with oxycodone to alleviate or prevent opioid-induced constipation in cancer pain patients. However, there is still concern that oral naloxone may precipitate opioid withdrawal symptoms in patients on opioids. We retrospectively investigated clinical characteristics of cancer patients who experienced opioid withdrawal symptoms. Methods: We reviewed medical records of all patients who were prescribed with oral oxycodone/naloxone at a tertiary cancer center from January 1, 2012 through December 31, 2016. Eligible patients were screened based on demographics, opioid and naloxone dosages, clinical manifestation and pain intensity. Results: Among a total of 1,641 patients, 10 patients were selected. Seven patients were male, and the average age was 68.1 years. The median dose of naloxone that induced withdrawal symptoms was 20 mg. Most common withdrawal symptom was shivering (seven patients) followed by cold sweating (five), and muscle twitching (five). Other symptoms included restlessness, fever, dizziness, and yawning. Pain was exacerbated from the median intensity of numeric rating scale (NRS) 3 to NRS 6. Conclusion: Opioid withdrawal symptoms may occur when switching to oral oxycodone/naloxone for cancer patients who have been treated with other strong opioids. A prospective, multicenter study on this issue should be conducted in future.

This study investigated population characteristics that influencing treatment service use of people who are voluntarily using drug dependency treatment services by using logistic and hierarchical regression analysis. The research model of the current study was driven by the framework of the 'the Behavioral Model of Health Services Use(the Andersen model)' that has been broadly applied to study on health behavior. This study used data from a sample group of 80 adults by using purposive sampling. This study found that some predisposing factors, enabling factors and need factors have direct effects on service use. In detail, individuals who graduated from high school use drug dependency treatment utilities more than those who did not. Further, individuals who were given more support from family, peers, or others, use the treatment utilities more frequently and were more willing to use the utilities continuously. Furthermore, the greater the perceived need felt by the dependent, the greater the tendency to enter hospitals or shelters. The important implications of this study for social work practice and social policy can be summarized as follows: first, this study supports the idea that intervention for drug dependents in Korea should be focused on environment resources rather than population characteristics; and government must support drug dependent treatment systems; the present study was the first to investigate Korean drug dependents through taking a more positive view, as well as the first to apply 'the Behavioral Model of Health Services Use', and as such represents an example of how studies could be productively conducted in the future. Despite these implications, there remain some limitations in this study. These include the following: limitation in generalizability of the results; the cross-sectional nature of the study design; survey research through the questionnaire method; using foreign scales; and the difficulty of classifying treatment settings.

Although liquid-liquid extraction (LLE) method has been used routinely for the analysis of amphetamine-like drugs (amphetamine; AP, methamphetamine; MA, 3,4-methylenedioxyamphetamine; MDA, 3,4-methylenedioxymethamphetamine; MDMA, 3,4-methylenedioxyethylamphetamine; MDEA), a solid-phase extraction (SPE) method, which can be automated, was applied for the simultaneous determination by GC/MS in human urine. Urine samples (3 mL) and 0.1 M phosphate buffer (1 mL, pH 7.0) were extracted by an automated SPE system. The eluent was evaporated, derivatized with trifluoroacetic anhydride (TFAA), and analyzed by GC/MS. The calibration curves was linear with correlation coefficient ($r^2$) above 0.994 in the ranges of 34.0 (AP), 28.0 (MDA)~1000.0 ng/mL for AP, MDA, and 50.0~2000.0 ng/mL for MA, MDMA, and MDEA. The limits of detection ranged from 4.0 to 10.0 ng/mL, and the limits of quantitation ranged from 12.0 to 34.0 ng/mL. The relative recoveries were 93.5~107.7 %. The precisions and accuracies were 1.9~14.8 % and -8.7~14.8 %, respectively. The present method was successfully applied to identify the MA or Ecstasy (MDMA) abusers in exact as well as rapid.

近讀2004年发表的一篇综述"乳腺癌外科手術发展史"的文章, 其中虽然广徵中外文獻, 追溯认识与手術治疗该病的源头直至古希腊着名医生希波克拉底, 但對近世日本医家在这方面所做工作却未见言及. 由此可知我们對邻邦的了解还十分不够. 而作爲这段歷史及其主人公华冈靑洲的有味之處, 幷非仅仅在于较早地使用麻藥, 完成世界首例乳癌切除手術. 靑洲以'內外合一, 活物穷理'爲核心理念；在尊崇中國传统医學的基点上吸收荷兰外科技艺, 成爲汉兰折衷的'华冈流'医學流派. 在全面了解华冈靑洲及集其大成的弟子本间枣轩之生平, 业绩后, 借助与汉代同类医家华佗的比较, 期待能够与讀者一同步入有關中日兩國科技发展歷程中异同点的深入思考.

오늘날 독자들을 매료시키고 있는 디지털 문학이란 과연 19세기 소설처럼 온화하고 책임감 있는 것일까, 아니면 환각 작용을 일으키는 마약처럼 위험스럽고 치명적인 것일까, 현재 우리는 뉴미디어 혁명의 한가운데에서 있다. 14세기의 인쇄 활자나 19세기의 사진 기술이 당대의 사회와 문화에 혁명적인 충격을 주었던것처럼, 이제는 모든 문화가 컴퓨터를 매체로 생산 ㆍ배포ㆍ의사소통하고 있다. 본고에서는 헐리우드 공식을 기반으로 한ㆍ미ㆍ일 애니메이션 시나리오 구성 방식으 비교했다.

밀가루 음식을 유난히 좋아하는 사람들이 있다. 과연 이들이 밀가루 음식을 좋아하는 이유는 무엇일까? 만약 당신이 밀가룰 음식을 남들보다 유난히 좋아한다면 '밀가루 중독'을 한번 의심해 바야 한다. 밀가루는 무슨 마약도 아니고, 담배도 아닌데 무슨 중독이냐고 묻겠지만 밀가루는 분명 중독성이 강하면서 우리 몸에 유해하며 살을 찌우는 식품이기도 하다.
