  • In this paper, we analyzed the effects of doctoring process on the patterns of Ag ink in gravure off-set printing. The parameters of doctoring process were the angle and the pressure, which was represented by the depth of blade movement to the gravure roll, of doctor blade to the surface of gravure roll, and the angle of patterns engraved on the gravure roll to the doctor blade moving direction. The proper parameters were extracted for the fine patterns and they were 15 mm for the pressure, $60^{\circ}$ for the blade angle. And the angle of patterns with respect to the blade movement should be less than $40^{\circ}$ for the best results. The gravure off-set printing with the above parameters was carried out to print gate electrodes and scan bus lines of OTFT-backplane for e-paper. The line width of $50{\mu}m$ was successfully obtained. The thickness of electrodes was $2.5{\mu}m$ and the surface roughness was $0.65{\mu}m$ and the sheet resistance was $15.8{\Omega}/{\Box}$.

  • This study was designed to evaluate the beekeeper's consciousness for diagnosis and treatment on a disease of honey-bee in Daejeon and Jeollanamdo in Korea. The questionnaire consisted of 14 questions. Of 231 randomly selected respondents between February and May 2010, 47.6% was consult a 'club (colleague)', 89.2% treated a 'doctoring oneself', 84.4% was recognize a bee as 'domestic animal', 77.5% was not recognize a veterinarian as field of treatment, 38.5% was acquire know-how by a beekeeper. Therefore these results suggest that the beekeepers are relying a lot on individuals experience for the diagnosis and treatment on the disease of honey-bee, the apiculture techniques was gained much by oneself. Korean beekeeping association was played a role as well, but related-university, agriculture research & extension services and veterinary service laboratory was not played a role in the country.

  • 2010년 가장 중요한 보안 이슈 중 하나는 무선 네트워크이었다. 스마트폰의 보급이 본격화되면서 무선 인터넷 사용자가 급증하였고 무선 AP가 전국에 우후죽순으로 설치되었다. 그러나 대부분의 무선 AP가 보안적인 관점에서 제대로 관리되지 않고 있고 무선랜 이용자 또한 보안의 중요성을 인식하지 못하고 있다. 이러한 상황은 심각한 보안위협을 초래할 수 있다. 본 논문에서는 QR 코드를 통해 악성코드를 유포, 모바일 AP 기능 활성화를 통해 대량 과금을 유발하는 새로운 방식의 사이버 공격 기법을 설계하고 분석하였다. 제안한 새로운 취약점은 안드로이드폰의 모바일 AP 기능을 강제로 활성화시킨 후 주변에서 발생하는 모든 Probe Request에 대해서 응답하게 하여 과금 유발 및 통신 장애를 유발한다.

  • In this experiment, we have manufactured thermal-curable silver pastes for direct printing. And to enhance conductivity, printability, adhesion and hardness during polymer direct-gravure prints, we have manufactured Ag pastes by adding variety of filter contents. Then we have investigated characteristics of rheology in paste according to the gravure printability and the properties of printed conductive patterns. Depending on a variety of Ag powder, there was a big difference in sharpness of printed pattern. And also by the use of carbon, there was a big difference in amount of solvent used, conductivity and in hardness. We could improve doctoring and the sharpness of a pattern by adding Ag paste in carbon particle, but as we have used nano-sized particle, there was an increase in the amount of solvent used and also we have found out that it gives a bad effect as adhesive and hardness becomes weaker. Even though Ag particle has the same spherical shape, the surface treatments could differ from one another. And by the appropriate choice and with the suitable combination of Ag powder, excellent printability and conductivity could be obtained.

  • Medical humanities education (MHE) is as essential as basic medical sciences and clinical medicine education. Despite the importance of MHE, MHE curriculum development (CD) has proven to be challenging. This critical review examines the MHE CD at one medical school. The critical review methodology was developed based on Kern's six step CD model to systematically examine the CD of "Doctoring and Medical Humanities (DMH)" at the Yonsei University College of Medicine. Five review questions were developed related to (1) necessity, (2) direction and purpose, (3) design, (4) operation, and (5) evaluation of CD based on Kern's model. The review showed that the process of DMH CD mapped to components of Kern's model. The DMH curriculum content selected was closely related to medical practice and aimed to combine the acquisition of understanding and skills by designing a student-participatory curriculum based on clinical cases. Assessment methods that emphasized students' reflections were actively introduced in the evaluation section. Since the regular committee for DMH continued the work of the special ad hoc committees for DMH CD, the CD was effectively completed. However, the planning and evaluation functions and responsibilities of the DMH committee need to be strengthened. Despite the apparent limitations, the fact that students showed a high satisfaction rate and preferred small group discussions based on clinical cases has significant implications in the instructional design of MHE, where changes in self-awareness and attitude are more important than the acquisition of information. It is necessary to systematically review and study students' reflection results produced by the changed assessment methods and to develop assessment indicators for MHE that reflect the achievements of the MHE competencies of students.

  • I examined throughout where Sa Gi Gang Boo Byung Hyung(邪氣藏府病形) was shown. It is shown in many books, such as Young Chu(靈樞), Kab Eul Kyung(甲乙經), Nan Kyung(難經), Yu Kyung(類經), etc. Sa Gi Gang Boo Byung Hyung got its name by how its contents pointed to the mechanism of getting harmed by Sa Gi(邪氣), and the forms of diseases which were led from five organs and six hollow viscera getting harmed by Sa Gi(邪氣). Sa Gi Gang Boo Byung Hyung is divided into three chapters which are divided altogether into nine sections. The first chapter is on the mechanism of Sa Gi(邪氣)' s harming the five organs and the six hollow viscera. Going into details, it discusses that Sa Gi has got two different ways which are divided into Yum Yang(陰陽) to harm the organs and the hollow viscera. Next, it discusses how faces can endure the cold that well. The second chapter is on the essences such as symptoms, face colors, shapes of pulse, and conditions on the interior part of the elbow. In the first section, it discusses how figures, colors and pulses relate together. In the second section, it discusses different diseases have different pulses and conditions on the interior part of the elbow. The third section is on forms of diseases in five organs and six hollow viscera. The third chapter is on acupuncture. The first section is about acupuncturing six channels. The second is about acupuncture points which is compared to the sea by its function. The third is about the forms of diseases with discussing symptoms and acupuncture points. The forth is about the essence of acupuncture. The ten different pulses of each five organs, and the masses of five organs in Nan Kyung(難經), and Jang Bu Mak Jin Beob(臟腑脈診法) in Eu Hak Yib Moon(醫學入門) are based on 'The six different pulses of each five organs' which is shown in the third section, second chapter. Besides, it plays an important role in study and it can play an important role as well in doctoring such as inspecting, taking pulses and so on. Thus, I found Sa Gi Gang Boo Byung Hyung worth while to study. But, Sa Gi Gang Boo Gyung Hyung was written in ancient letters and was omitted in many parts, which led successive doctors to write different explanatory notes. Thus, I researched the exact meaning through successive explanatory notes.

  • 본고는 고소설에 표출된 영웅의 시대별, 남녀별 차이에 드러나는 영웅의 유형화와 소설의 개별적 양상과 그 역사적 의미에 대하여 고찰해 보았다. 이러한 목적을 달성하기 위해 본고에서는 <최고운전>, <전우치전>, <전관산전>, <일념홍>, <여영웅>을 텍스트로 선정하였다. 그리고 이들의 주인공들을 '문화영웅-최치원, 민중영웅-전우치, 내조(가정) 영웅-정소저, 친일 개화 영웅-일념홍 이형경'으로 유형화하였다. 또 이 영웅의 유형이 갖는 역사적 의미를 서술하여 본고의 목적을 이루려고 노력하였다. 중국과 조선은 국경을 맞대고 있기에 서로의 관계가 불편했다. 이러한 문제와 관련된 것이 바로 <최고운전>의 최치원이다. 최치원은 신라의 대문장가였기에 중국 문사와 한 수 우위의 시문수창을 할 수 있었다. 조선이 중국보다 문화가 우수하다는 자부심을 표현하기 위해 문화영웅 최치원이 필요했다. 조선은 반상제도가 뚜렷한 유교사회였다. 그렇다보니 모든 중심은 양반에 치우쳐 있어서 민중들은 양반에 의해 핍박을 받았는데 이 때 민중의 영웅이 필요했다. 그가 바로 <전우치전>의 전우치다. 전우치는 도술을 통해 민중들의 원한과 바람을 해결해 주는 진정한 민중영웅이라 할 수 있다. 조선 후기로 가면서 전란을 체험한 여성들이 남성을 대하는 태도가 달라진다. 그렇다 보니 <강도몽유록>이나 <박씨전>, 그리고 <이학사전>과 같은 여성영웅소설이 등장한다. 무능한 남성들로 인해 울분에 찬 여성들에게 당시 작가는 작품에서나마 희망을 주었다고 생각한다. <전관산전>의 정소저는 고소설에 충실한 여성주인공보다는 진취적이지만 남편을 위한 내조를 담당하는 가정영웅이다. 조선은 청일전쟁과 러일전쟁을 거치며 일본의 마수에 걸려든다. 이후 일본은 을사늑약을 강조로 맺은 뒤 통감부 정치를 실시한다. 이 때 친일을 부각하고자 친일신문을 발간하고 친일 소설을 연재한다. 바로 <일념홍>과 <여영웅>인데 친일개화 영웅이다.
