Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

본 연구는 기존연구와 달리 프랜차이즈 산업 중 외식프랜차이즈 산업만을 대상으로 하여 거래관계를 분석하고 있다. 본 논문은 외식프랜차이즈 산업에 있어 가맹본부와 가맹점간의 거래관계-관리특성과 불공정거래-가 가맹점의 신뢰와 성과에 어떠한 영향을 미치는 가를 실증분석하고 있다. 연구목적을 달성하기 위해 기존 연구결과의 문헌연구를 통해 외식프랜차이즈 가맹본부와 가맹점간의 관계 규명을 위한 연구가설을 설정하고, 이를 실증분석하기 위하여 외식프랜차이즈 가맹점을 대상으로 설문조사를 실시하였다. 설문조사결과 총 153부를 회수하였고, 설문응답이 불성실한 설문지 33부를 제외한 후 총 125부를 사용하였다. 분석결과, 외식프랜차이즈 가맹본부의 관리특성 요인 중 가맹점교육과 종업원교육이 가맹점의 신뢰를 향상시키는 것으로 분석되었다. 또한 관리특성 차원인 가맹점 관리 매뉴얼과 종업원 교육이 가맹점의 영업성과에 영향을 미치는 것으로 분석되었다. 반면, 가맹본부의 불공정거래는 가맹점의 신뢰와 성과에 영향을 미치지 않는 것으로 분석되었다. 본 연구결과의 시사점은 가맹본부와 가맹점의 성과를 동시에 증진시키기 위해서는 무엇보다도 교육과 신뢰를 바탕으로 한 관계유지가 중요하다는 것이다. 이를 위해서 가맹본부는 가맹점과의 신뢰구축을 위해 지원방식의 다양화와 교육지원의 체계화 방안을 모색하고, 정부는 외식산업의 불공정거래 행위를 근절시킬 수 있는 방안이 모색되어야 한다. This paper is an exploratory survey that examines franchising in Korea. Based on a literature synthesis, we extract the four constructs: managerial characteristics, support, unfair trade and trust. We hypothesize that these four factors influence the trust and performance of franchisee. In order to examine these hypotheses empirically, we conducted a survey on the database of the Franchising Council of Korea in Korea. In total, l35 completed questionnaires were received in total, of which 128 were usable. By analyzing the data, we can confirm most hypothesis supposed. The paper contributes to understanding franchising in Korea. It offers some insights and assistance to franchisers hoping to open up franchises. the main contribution of this paper to the measurement issues related to franchisee`s performance is onefold: it estimates some determinant factors (managerial characteristics, support, unfair trade and trust) of franchisee`s performance. This study thus provide franchisers and practitions, who plan to extend their franchising business, with some practical knowledge.

The steganography is one of methods that users can hide data. Some steganography softwares use audio data among multimedia data. However, these commercialized audio steganography softwares have disadvantages that the existence of hidden messages can be easily recognized visually and only certain-sized data can be hidden. To solve these problems, this study suggested, designed and implemented Dynamic Message Embedding (DME) algorithm.Also, to improve the security level of the secret message, the file encryption algorithm has been applied. Through these, StegoWaveK system that performs audio steganography was designed and implemented. Then, the suggested system and the commercialized audio steganography system were compared and analyzed on criteria of the Human Visible System (HVS), Human Auditory System (HAS), Statistical Analysis (SA), and Audio Measurement (AM). 멀티미디어 데이타중에서 오디오데이타를 이용한 상용화된 오디오 스테가노그라피(audio steganography) 소프트웨어들은시각적인 측면에서 비밀 메시지가 은닉되어 있다는 것을 쉽게 인지할 수 있다는 것과 숨길 정보의 크기에 제한이 있다는 문제점을 가지고 있다. 이러한 문제점을 해결하기 위해 동적으로 메시지를 은닉하는 방법을 제안하였다. 또한 비밀 메시지의 보안수준을 향상시키기 위해 파일 암호화 알고리즘도 적용하였다. 본 논문에서는 제안한 오디오 스테가노그라피를 수행해주는 StegoWaveK 시스템을 상용화된 오디오 스테가노그라피 시스템의 5가지 측면으로 비교 분석하였으며, 성능면에서 우수함을 보였다. StegoWaveK 는 상용화된 시스템에 비해 시각적 공격 측면이나 은닉할 메시지 크기 측면에서는 좋으나 인터페이스 측면에서는 사용자 위주의 편리성을 제공할 수 있도록 보완되어야 한다. 그리고 StegoWaveK와 상용화된 시스템이 견고성이 약하다는 단점을 보완해야 하며, 다양한 멀티미디어 데이타를 이용한 스테가노그라피로의 추후연구가 필요하다.

Hea-Young, Park,Hee-Kyung, Rhee,Ji Hye, Yoo,Eun Young, Lee,Young Joo, Kwon,Hang-Rhan, Seo,Yun-Sil, Lee 梨花女子大學校 藥學硏究所 2012 藥學硏究論文集 Vol.- No.22

Thirty 2-phenylquinazolin-4(3H)-one derivatives were prepared and their cytotoxic activities were tested in five human tumor cell lines. Some compounds (Se, Sk, St. 6c and 6f) showed relatively high cytotoxic activity. Especially, compound 6c showed the most cytotoxicity against all cell lines tested among the synthesized derivatives, and the inhibitory activity of 6c against Hela cell was higher than that of adriamycin. The putative mechanism of antitumor action in apoptotic cell death was cell cycle arrest in the GO/Gl phase by compounds Sk, Sv, Sm. 6c, and 6f in Hela cells. These compounds showed relatively high cytotoxicity in this cell type.

Purpose: This study was conducted to investigate the performance level of breastfeeding health behaviors and general characteristics of breastfeeding mothers related to breastfeeding health behaviors. Method: 123 breastfeeding mothers whose infants are between 5-7 months of age participated in this study. Data was collected during a Breastfeeding Infant Contest held in September 2007 in Changwon-si, Gyeongsangnam-do. Health behaviors related to breastfeeding were measured in Likert scale 5 including 20 questions developed by Park et al., and the collected data was analyzed with descriptive statistics, T-test and ANOVA using SPSS program. Result: The performance level on breastfeeding health behaviors scored 3.73±.35 on average (5.0 in full score). The score showed that there were significant statistical differences only in the knowledge of breastfeeding between groups. The score of `enough` knowledge group was higher than that of `a little short` knowledge group (t=2.071, p=0.045). Conclusion: The performance level on breastfeeding health behaviors was related to the knowledge of breastfeeding in breastfeeding mothers. Therefore, it is necessary to enhance education on breastfeeding health behaviors for mothers of newborns in the hospital and to have a reevaluation process on their performance at the time of revisiting.

Endothelial progenitor cell homing: prominent role of the IGF2-IGF2R-PLCβ2 axis

Maeng, Yong-Sun,Choi, Hyun-Jung,Kwon, Ja-Young,Park, Yong-Won,Choi, Kyu-Sil,Min, Jeong-Ki,Kim, Yun-Hee,Suh, Pann-Ghill,Kang, Kyung-Sun,Won, Moo-Ho,Kim, Young-Myeong,Kwon, Young-Guen American Society of Hematology 2009 Blood Vol.113 No.1

<B>Abstract</B><P>Homing of endothelial progenitor cells (EPCs) to the neovascular zone is now considered to be an essential step in the formation of vascular networks during embryonic development and also for neovascularization in postnatal life. We report here the prominent role of the insulin-like growth factor 2 (IGF2)/IGF2 receptor (IGF2R) system in promoting EPC homing. With high-level expression of IGF2R in EPCs, IGF2-induced hypoxic conditions stimulated multiple steps of EPC homing in vitro and promoted both EPC recruitment and incorporation into the neovascular area, resulting in enhanced angiogenesis in vivo. Remarkably, all IGF2 actions were exerted predominantly through IGF2R-linked G(i) protein signaling and required intracellular Ca2+ mobilization induced by the β2 isoform of phospholipase C. Together, these findings indicate that locally generated IGF2 at either ischemic or tumor sites may contribute to postnatal vasculogenesis by augmenting the recruitment of EPCs. The utilization of the IGF2/IGF2R system may therefore be useful for the development of novel means to treat angiogenesis-dependent diseases.</P>
