The study is written for the purpose of examining Na Cheon Ik(羅天益)'s medical ideology mentioned in Euian(醫案) of "Wi-saeng-bo-gam 衛生寶鑑". The publication of this book is reflected in the 13th century perplexed conditions. In this thesis, after the writer analyzed Na Cheon Ik(羅天益)'s medical theory in "Wi-saeng-bo-gam 衛生寶鑑", knew that he emphasized practical use on all occasions. So far, Na Cheon Ik(羅天益)'s medical ideology in "Wi-saeng-bo-gam 衛生 寶鑑" is hardly studied. "Wi-saeng-bo-gam 衛生寶鑑" is a medical book which was written in the process of systemic recognized of medical theories of various and special academic parties in the period J inYuan(金元). The medical theory that appears in "Wi-saeng-bo-gam 衛生寶鑑" is rooted in Li Dong Yuan(李東垣)'s theory, but also Na Cheon Ik(羅天益)'s medical ideology is distinguished from Li Dong Won(李東垣)'s ideology. First of all, Na Cheon Ik(羅天 益) recognized the importance of discerning not only On-Bo(溫補) but also Han-Ha-To(汗下吐) and various ways in medical treatment. Secondly, the fact that Na Cheon Ik(羅天益) made good use of moxibustion tells the difference between the two. In conclusion, "Wi-saeng-bo-gam 衛生寶鑑" holds systemic medical information which was originated with Na Cheon Ik(羅天益)'s various and special experience. He had contributed in the clinical experience and medical information by having an effect on the ages to come.

Wi-Fi Direct는 Wi-Fi Alliance에서 인증한 Wi-Fi 기반기술로 AP (Access Point)나 라우터 같은 인프라장비 없이 단말 간에 직접 통신을 하는 프로토콜 방식을 의미한다. Wi-Fi Direct는 현재 스마트폰 뿐만 아니라 TV, 노트북, 프린터, 카메라와 같은 다양한 기기 등에 탑재되어 단말 간 직접 통신을 통하여 콘텐츠 및 서비스를 사용할 수 있는 기술이다. 본고에서 Wi-Fi Direct 기술을 동작 단계별로 구체적으로 살펴보고 새롭게 정의된 전력 절감 기술에 대해서도 살펴본다. 또한 Wi-Fi Direct 기반 응용 서비스를 알아본다.

Anorexia is a common symptom in the elderly patients. Causes of anorexia in the elderly are very diverse and multifactorial. Causes include physiological changes associated with aging, mental disorders such as depression, anorexia tardive, dementia, medical diseases such as cancer(lung and gastrointestinal cancer), benign gastrointestinal disorders, cardiac disorders, pulmonary disease, thyroid disorders, infection. Medications such as digoxin, theophylline have also been implicated in the problem. No cause is found in about one quarter of patients. Management is directing at treating causes and providing nutritional support. In Oriental medicine, the appetite has close relation to Biwi. The main cause of anorexia is the insufficiency of Biwi. The physiology of Biwi is that Bi sends clarity(food essence) upward and Wi sends digested food downward. Specially if the physiologic function of Wi is disordered by various factors, Wi cannot send digested food downward. As a result, the anorexia can present by the disorder of Wi function. We experienced a case of an 74 years old female patient with ill-defined severe anorexia differentiated as Wijoongheohan. The patient was managed with fluid therapy and Jeonghyangsiche-tang. The anorexia and other symptoms improved continuously during hospitalization.

Through this research author discovered the fact that Na Cheon-ik inherited the 'Bi Wi Nai Sang Seol' of Lee Ko, which bases spleen and stomach as the fundamentals of our body, and stated the importance of rise of the spleen ki. He also stated the ways in which spleen and stomach could be damaged and in doing so, he made sub-divisions into 'Sik Sang Bi Wi Ron' and 'Eum Sang Bi Wi Ron' to explain how the diseases and treatment could be different. As well, he presented the importance of the relationship between the five visceras and the dialectics of triple energizer.

Field surveys were conducted from May 2016 to October and from April to October 2017 in Tributary Region of Middle Stream of the Nakdong River. The survey was carried out at 66 sites including Young-gang 11, Naeseong-cheon 21, Wi-cheon 16, and Gam-cheon 9, Byeongseong-cheon 9. As a result of investigation, 474 taxa in total ; 99 familly, 288 genera, 421 species, 4 subspecies, 39 varieties and 10 forma. Among them, 5 Korean endemic plants, 7 rare plants, 31 taxa were listed as Floristic Target Species in Korea. Naturalized plants was confirmed 73 taxa, their Urbanization Ratio 22.7%, and naturalization ratio 15.4% in the investigated area. The Life form(Dormancy form) review results as follows ; Therophytes 159 taxa, Hemicryptophytes 91 taxa, Hydrophanerophytes 68 taxa, Geophyte 52 taxa, Nanophanerophytes 35 taxa, Megaphanerophytes 32 taxa, Microphanerophytes 25 taxa, Chamaephytes 12 taxa, and Epiphyten 1 taxa.

In this paper wideband dipole antenna that is usable as PCS/WCDMA/WiBro/WiMax public relay station antenna is proposed. The proposed antenna that designed by using double ring structure improves bandwidth performance of existing dipole antenna to wideband performance. To verify wideband performance and isotropic radiation pattern of the proposed antenna, simulation and fabrication have progressed its radiation characteristic has measured and then compared with calculated result. Measured result is similar to calculated result and has gain of 2dB VSWR of 2:1 over 1.75~3GHz. It is considered that the dipole antenna that designed in this paper can be usable as PCS/WCDMA/WiBro/WiMax public relay station antenna.

이동중인 단말에게 인터넷 서비스를 제공하고자 하는 WiBro 시스템은, 무선자원의 효율적인 사용을 위해서 전송할 데이터가 있는 단말들에게만 대역폭을 할당하는 demand-based 대역폭 할당 방식을 사용한다. 이때 여러 단말들이 동시에 데이터를 전송하고자할 경우 충돌이 발생하므로 이들의 전송순서를 정해주는 것이 필요하다. 기존의 WiBro 시스템에서는 binary exponential backoff algorithm 에 기초한 random access 기법을 사용하는데, 본 연구에서는 conflict resolution 기법에 기초한 새로운 random access 기법을 제안하고, 새로운 기법의 성능이 보다 우수함을 시뮬레이션을 통해 보였다.

흑백 1채널 이미지를 3 채널 이미지로 색상화하고 Super-Resolution하여 의미 있는 정보 얻도록 한다. CCTV, 군사용 카메라, 차량용 블랙박스 등 많은 분야에서 주간에 촬영된 영상은 컬러 이미지로 많은 정보를 얻을 수 있다. 하지만 야간에 촬영된 영상은 빛이 없어서 영상에서 정보를 얻기가 원활하지 않다. 따라서 DCGAN을 통해 단일 채널의 흑백 이미지를 3채널의 색상화 이미지로 만들고, Super-Resolution 기술을 적용해서 해상도를 높여 가시광선이 없는 야간이나 어두운 공간에서도 의미있는 영상을 얻을 수 있도록 한다.
