Objectives : The focus of the review was laid on differences in research pertaining to thread embedding acupuncture between domestic and foreign journals. Methods : We collected 53 Korean articles on thread embedding acupuncture study from 4 Korean article searching sites, and 80 foreign articles from Pubmed. We analyzed the number of the theses according to the publication year, study method, journal, and subject. Results : A total number of 134 thread embedding acupuncture articles were categorized as 100 clinical trials, 14 experimental papers, and 19 literature reviews. Of the collected clinical trials, 55 were case studies, 6 were CCTs and 39 were RCTs. The domestic clinical trials were comprised of 36 case studies, 1 CCT, and 2 RCTs, and foreign clinical trials were comprised of 19 case studies, 5 CCTs, and 37 RCTs. Although only 12 of the 39 domestic clinical trials exclusively treated thread embedding acupuncture to the experimental group, 38 out of 61 foreign clinical trials undertook thread embedding acupuncture as the sole treatment. While the 2 domestic RCTs research had no significant evidence that the experimental group was different from the control group, the experimental group demonstrated better responses than the control group in 31 of the 37 foreign RCT studies. Conclusions : Studies on thread embedding acupuncture are more intensively studied in the foreign field in comparison to the domestic field. Referring to the results from the foreign thread embedding acupuncture studies, domestic use of thread embedding acupuncture should be expanded. Also, more refined research needs to be conducted in the domestic field in order for the Koran medicine to lead the thread embedding acupuncture. This study is limited in that the literature search in the foreign journals were restricted.

ObjectivesWe will provide basic information on bee venom clinical tests and aid the practical use of bee venom in such tests, through examination of RCT research related to bee venom that was reported domestically. MethodsWe collected 365 articles on Bee venom study result from the OASIS system using the Keyword ‘bee venom, apitoxin, apitherapy, bee sting’. The initially selected theses were primarily screened for clinical research. Out of these, case studies and non randomized controlled trial (non-RCT) were ruled out. As a result, 39 studies of randomized controlled trial (RCT) research were chosen as the subjects of study. ResultsRCT research related to bee venom was first presented in 2003, and 39 studies have been published until 2012. 18 studies were tests to confirm the effectiveness of bee venom, 7 studies were comparisons between SBV and BV, and 13 studies were comparisons with other types of treatment. Research conducted through appropriate randomization methods were 20 studies, and inappropriate randomization methods were used in 19 studies. In therms of Jadad score, 12 studies received 4~5 points, 15 studies received 1~3 points, and 12 studies received zero point. ConclusionsIn order to assure good quality RCT research, appropriate guidelines should be provided, and proper evaluation standards should be established. In-depth study is needed concerning the difference of responses to treatment according to the types of treatment received. A standardization of treatment should be reached as a result.

일제강점기 총기 규제 정책 연구

이용석 ( Lee Young-seok ) 수선사학회 2021 史林 Vol.- No.78

This thesis is a review of gun control policies before and after the annexation. of Korea by Japan. Securing firearms and ammunition was essential in the armed struggle of Righteous Armies. Therefore, during this period, Righteous Armies used various methods to obtain and supply firearms and ammunition. There were several methods of securing firearms, such as requisition from the people, seizing weapons from the army or police station, smuggling from foreigners, manufacturing or modifying firearms, and so on. The weapons of them came as a great threat to the Japan trying to annex Korea. To prevent this, Japan enacted the Guns and Gunpowder Control Act and introduced strong firearms regulations in Korea. After this, an ordnance committee was established nationwide, and firearms of the korean government and civilians were confiscated. Through this process, private ownership of firearms in Korea became almost impossible. The strict gun control in korea continued even after the annexation. In 1912, the Governor-General enacted a new Guns and Gunpowder Control Act. In addition to the existing strict gun control laws, this law contained stricter regulations than previous laws, such as a strict ban on the manufacture of military firearms and gunpowder in Korea. In addition, in order to restrict the possession of firearms by Koreans, gun regulations were newly introduced only for Koreans. A typical example is the so-called ‘Internal Discipline Article 18’. The regulation contains a number of strong restrictions on gun licenses for Koreans. The first clause stipulated the types of Koreans who could obtain gun licenses, and the third clause limited the number of gun licenses. The fourth clause restricted the types of firearms that Koreans could possess. These regulations made it impossible for Koreans to own firearms except for a small number of professional hunters and verified pro-Japanese groups. In addition, even after obtaining permission for firearms, the Japanese placed them in a surveillance network and monitored them periodically. This consistent and strong gun control is a tangible example that clearly shows Japan's intention to suppress the struggle for independence in Korea by blocking the possession of guns by Koreans.

증례보고 : Osler- Weber- Rendu 증후군 환자의 전신마취 경험

Hereditary haemorrhagic telangiectasia (HHT), or Osler-Weber-Rendu syndrome is an autosomal dominant disorder characterized by recurrent epistaxis, mucocutaneous telangiectasias, and visceral involvement including arteriovenous malformations that may develop in any organ, especially in the lung, brain, liver and GI tract. Early screening and regular follow up of patients with HHT are important to minimize the risk of development of serious sequelae. We report a case of 46-year-old female patient who had "suspected HHT" and review the literature on this rare disease. (Korean J Anesthesiol 2007; 52: 363~6)

본 논문에서는 DIBR 3 차원 영상을 위한 블라인드 워터마크 방법을 제안한다. DIBR 을 이용한 3 차원 영상은 낮은 Bitrate 와 시점조정 가능성으로 인해 주목받고 있지만, DIBR 과정 중 워터마크 손상이 발생해 워터마크에 어려움이 있다. 이를 극복하기 위해 DIBR 의 특성을 이용한 깊이영상 기반으로 워터마크 삽입 영역을 탐색하는 방법을 사용하며, 이를 통해 시점이동에 민감하지 않은 영역에 워터마크를 삽입하는 것이 효과적임을 실험적으로 증명하였다. 또한 시점이동 후 사라질 가능성이 큰 불필요한 워터마크 삽입을 최소화하여 워터마크 삽입 후 영상의 화질저하를 줄였다. 이에 본 논문에서는 깊이영상을 이용해 변화가 적은 영역을 탐색하기 위한 연구를 진행하였다. 이는 후에 가상 시점 영상에 추가적인 공격이 가해지더라도 더 강인성을 가질 수 있는 기초가 되었다. 또한 블라인드 워터마크 방법을 적용하기 위해 기존 워터마크 데이터와 유사도를 측정하는 방식으로 워터마크 삽입 위치를 파악하였다.

This paper proposes a digital watermarking scheme to protect the ownership of the freeview 2D or 3D image such that the viewer watches the image(s) by rendering a arbitrary viewpoint image(s) with the received texture image and its depth image. In this case a viewpoint change attack essentially occurs, even if it is not malicious. In addition some malicious attacks should be considered, which is to remove the embedded watermark information. In this paper, we generate a depth variation map (DVM) to find the locations less sensitive to the viewpoint change. For each LH subband after 3-level 2DDWT for the texture image, the watermarking locations are found by referring the DVM. The method to embed a watermark bit to a pixel uses a linear quantizer whose quantization step is determined according to the energy of the subband. To extract the watermark information, all the possible candidates are first extracted from the attacked image by considering the correlation to the original watermark information. For each bit position, the final extracted bit is determined by a statistical treatment with all the candidates corresponding that position. The proposed method is experimented with various test images for the various attacks and compared to the previous methods to show that the proposed one has excellent performance.
