Objectives: Both oncologists and family physicians have involved in care of cancer patients, and their knowledge and attitudes towards cancer influence cancer patient care. This study aims to compare knowledge, attitudes, and practice of cancer care between oncologists and family physicians. Methods: Total 102 questions related to cancer information needs and experiences of cancer patient cancer were asked to members of Korean Cancer Association and Korean Academy of Family Medicine through an email. Results: There were total 174 oncologists and 326 family physicians participated in the study, and their mean age and experience of practice were 43 and 37.2 respectively. Oncologists and family physician had different attitudes and preference regarding patients` informational needs related to ``adverse effects of chemotherapy`` and ``disease management other than cancer.`` It was statistically significant (P < 0.05). In addition, usage of cancer information was significantly different between the groups. They used ``cancer diagnosis and treatment guideline``, ``updated knowledge and experts opinion``, ``results of outcome studies``, and ``continuing education for cancer management`` information differently. Conclusions: This study was to investigate necessity and the importance of cancer information among oncologists and family physicians. Results of this study would be good reference for developing a database of cancer information for oncologists and family physicians so they could use cancer related information efficiently.

텍스트 형식의 암호는 가용성이 높고 비용이 저렴한 장점으로 인해 가장 널리 사용되는 방식이다. 사용자는 암호를 알고 있어야 하므로 기억하기 쉬워야하므로 대부분의 암호는 편향되어 규칙성을 보인다. 암호 크래킹의 대부분은 이러한 규칙을 기반으로 수행된다. 최근에는 GAN, RNN, LSTM의 딥러닝 모델을 사용하여 암호 크래킹 연구에 적용되고 있으며 또한 다가오는 양자 컴퓨터 시대에서는 Grover의 알고리즘을 사용과 편향된 암호의 특성을 기반으로 사용자 암호에 대한 위협이 될 수 있다.

Objectives: The objectives of this research were to develop and evaluate a mobile application for navigation program for cancer patients who might experience some difficulties in obtaining and understanding further schedules, directions due to flooding information at a time and scattered educational materials. Methods: A mobile application was developed an educational mobile app for cancer patients based on a systematic instructional design model called ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The developed application was evaluated by 76 users through a questionnaire of satisfaction. Results: A mobile app contains educational contents for cancer patients, based on their satisfaction, demand and knowledge about cancer education and information services. It contains management of symptoms, management of my schedule, and information about chemotherapy, FAQ, symptoms dangerous enough to contact the hospital, personal history about how to overcome cancer, hospital convenience facilities and education schedule of cancer center. A result of the evaluation of user's satisfaction showed 59.4% responding 'Satisfied' and 27.4% 'Very satisfied'. Conclusion: The personalized information and education contents for cancer patients by using the mobile application was given to cancer patient and then educational outcomes became more effective. The development of the application which persons can use regardless of time and place enables health care providers to acquire the foundation of the patients-oriented educational system. Education satisfaction and knowledge level was increased, after using mobile application.

본 연구는 국내 주요 식중독 원인균인 Staphylococcus aureus, Salmonella enterica subsp., Vibrio parahaemolyticus를 동시에 검출 및 동정할 수 있는 simultaneous multiplex PCR방법을 개발하고자 하였다. S. aureus의 23s rRNA 유전자(482 bp), V. Parahaemolyticus의 toxR 유전자(368 bp), S. enterica subsp.의 invA 유전자(284 bp)를 특이적으로 검출 및 동정할 수 있는 3개 primer set 즉, STA-5F/STA-5R, ToxR-F/ToxR-R, 139/141을 구축하였으며, 그 결과 정제되어진 각 식중독 원인균의 genomic DNA를 template로 하여 세 균주 모두 10 pg까지 다중동시 검출이 가능하였다. 생균수(CFU)와 상응되는 검출한계 결과로써 10¹~10² CFU/reaction의 검출한계를 보였으며 이는 즉, S. aureus 6.0×10⁴ CFU/mL, S. enterica subsp. 9.5×10⁴ CFU/mL, V. parahaemolyticus 6.1×10? CFU/mL의 검출한계를 나타내었다. 균체회수부터 agarose gel 상에서 검출 및 동정까지 3~4 hr의 시간 소요로 single tube 반응으로 세식중독 원인균의 다중동시검출이 가능하였다. 또한 추가적인 연구를 통하여 세 식중독 원인균주의 검출을 위한 향상된 민감도를 가지는 multiplex PCR법 및 real time PCR을 이용한 다중동시검출법 개발을 위한 기초자료로서 활용 가능할 것이라 사료된다. This study was conducted to detect and identify Staphylococcus aureus, Vibrio parahaemolyticus, and Salmonella enterica subsp. using simultaneous multiplex polymerase chain reaction (multiplex PCR) assay. 23S rRNA partial gene (S. aureus), tox R gene (V. parahaemolyticus), and inv A gene (S. enterica subsp.) as diagnostic marker gene were suggested, and their amplicon sizes were 482 bp, 368 bp, and 284 bp, respectively. Non specific amplicons by STA-5F/STA-5R primer, ToxR-F/ToxR-R primer, and 139/141 primer were not observed in genomic DNA of pathogen bacteria as Bacillus cereus, Listeria monocytogenes, Escherichia coli, Proteus vulgaris, Streptococcus pyogenes, Candida albicans, and Shigella sonnei. The extracted crude DNA of targeted bacteria was detected as PCR template successfully. The detection limits were 10<SUP>5</SUP>~10<SUP>4</SUP> CFU/mL and 10 pg of purified genomic DNA of S. aureus, V. parahaemolyticus, and S. enterica subsp. by using simultaneous multiplex PCR.

텍스트를 기반으로 하는 패스워드는 다방면에서 가장 많이 사용되고 있는 인증 수단이다. 하지만 이러한 패스워드는 사용자의 기억에 의존하기 때문에 사람들은 일반적으로 기억하기 쉽게 ‘!iloveY0u’와 같은 암호를 사용한다. 이로 인해 사용자들의 패스워드 간에 규칙성이 생기게 되어 HashCat과 같은 크래킹 도구에 의해 해킹될 수 있다. 딥러닝을 통한 패스워드 예측의 경우, 일반적인 패스워드 크래킹 도구와 달리 패스워드 구조 및 속성에 대한 사전 지식 및 전문적 지식 없이도 패턴을 추출하고 학습할 수 있어 활발히 연구되고 있다. 본 논문에서는 딥러닝 모델 중에서도 순환 신경망을 사용하여 텍스트 기반의 패스워드를 예측하는 연구의 동향에 대해 알아본다.

연구자들의 연구 결과를 공유하는 논문은 학회에 제출되어 심사를 거친 뒤 정식으로 등록된다. 이러한 과정에서 심사는 연구 윤리를 지키기 위해, 학회의 가치를 높이기 위해 시행되는 필수적인 과정이다. 하지만 이러한 심사 관리 과정에서 다양한 문제가 지속적으로 발생하고 있다. 본 논문에서는 기존의 시스템에서 발생하는 문제들을 해결함과 동시에 비용적인 면에서도 효율성을 제공하는 블록체인 기반의 논문 심사 시스템을 제안한다.

To contribute the basic data for spread of water fluoridation area, this study provide the awareness and attitudes of local residents for adding fluoride to tap water. The convenience sampling was chosen 534 persons of local residents in Dangjin-gun. Survey was performed from May to September in 2010; below 50 years old person surveyed by self-administered questionnaire method assisted with supervisor, above 50 years old person surveyed by interviewing method. The data analyzed SPSS Ver. 17.0. About the awareness of water fluoridation 49.1% of the subject answered "have heard", but 50.9% "not ever heard". People who answered in favor of the water fluoridation were 63.7%, who answered against were 11.2%. In policy decision method of water fluoridation they highly choose the survey of public opinion in 40.6%, followed by ballot 32.8%, by local government 18.9%, by local councils 5.4%, and other 2.2%. The 71.4% of respondents who replied "have heard" approved the water fluoridation, but only 56.3 percent of respondents who replied "haven`t heard" were in favor of that. More than 59.5% of university graduates respondents who answered "have heard" approved the water fluoridation. People with higher education degree more recognized it and the lower shows tend to be low awareness. In conclusion, to expand of water fluoridation area they need more publicity and education about it to local residents.
