이장천,Lee Jang-Cheon 대한한의학방제학회 2002 大韓韓醫學方劑學會誌 Vol.10 No.1

A therapeutic following confirming symptom(辨證施治) has a proper characteristic in oriental medicine, which can be grasped but by pathological body reflection not by histological or molecular level etiology. It is also able to be selected a prescription by means of clinical trials which promote human body's natural resurgent. Whereas, a therapeutic regimen prescription(定病傳方) has a merit in prescribing a disease to the point. which has been developed and established a therapy method naturally for thousands years. Then, which of the two is the better method in clinic? The answer is a co-exist of the two therapy methods in a matter of developing deciding therapeutic cooperation. To tie a knot, two methods need the opposite one.

Objectives : Angelicae gigas, A. sinensis and A. acutiloba are three types of plants used as Angelicae Radix (Dang-Gui). Many doctors of Korean medicine want to know the difference in clinical use of these three species. This study aimed to compare the hemoglobin-related activity of the extracts of Angelicae gigas, A. sinensis and A. acutiloba roots by measuring the intensity of binding oxygen to hemoglobin using Raman spectroscopy. Methods : Hemoglobin activity was measured by chemical analysis and Raman spectroscopy to compare the pharmaceutical efficacy of three Angelica root extracts. The oxygenated hemoglobin intensity, blood decursinol and acetylcholinestrase(AChE) concentration in mice were measured. In addition, the effects of three Angelica root extracts on oxygenated hemoglobin intensity, decursinol and AChE concentration in red blood cells (RBC) from human were also investigated. Results : The contents of decursin, decursinol and decursinol angelate, which affected physiological activity and RBC properties, were higher in the extract of A. gigas root than in those of A. sinensis and A. acutiloba roots. Moreover, oxygenated hemoglobin intensity in the A. gigas extract was higher than that of other two species in the blood of mice and human RBCs. Also, the blood decursinol and AChE concentrations of A. gigas root extract were higher than that of A. sinensis and A. acutiloba roots. Conclusions : These results suggest that A. gigas is more effective in treating disease related oxygen deficiency in RBC deformation under oxidative stress

Objectives : Astragali Radix is known as a perennial plant, and it is estimated that there may be differences in the contents and their components depending on the ages. The components of astragali radix may activate differently. Methods : The astragali radix components cultivated in Jecheon( one year ), Korea, Shanxi province( 7 years ), China, Inner Mongolia( 5 years) and Inner Mongolia ( 8 years ) were extracted with pure ethyl alcohol and identified the component molecules. The extracted components of astragali radix were measured the activity of Telomerase for confirmation of their Telomere lengths. Results : The cell activity has been shown the greatest contribution in astragali radix of Inner Mongolia(8 years). Although there is the difference in cell activity between the two products of the 5 and 7 years, the difference between the values was small and the 7 years product was slightly higher than 5 years product. Conclusions : Total Astragaloside contents were highest in the product of Inner Mongolia(8 years), followed by the 7 year product of Shanxi province. Especially, astragaloside and cycloastragenol (TA-65) among the astragali radix components have shown to be increased Telomerase activity in the DNA metabolism of the cells, and the efficacy depends on the ages of growth.

장천,은성종 차세대컨버전스정보서비스학회 2014 디지털예술공학멀티미디어논문지 Vol.1 No.2

Alopecia is a very popular research focus in the medical field. In order to help medical doctors with their study on human hair, we proposed and designed an automatic hair counting system. The approach in our system is based on DIHAM (Digital Image for Hair Analysis and Measurement). We utilize the classical binary transformation Otsu threshold for hair segmentation, and put emphasis on separating the single hair region for counting. In order to separate the single hair in an overlapping region, we use the Hough transformation. Experiments will be performed to demonstrate the effectiveness of our system. 탈모증은 항상 의학 분야의 핵심 연구이다. 본 연구에서는 의사의 요구사항에 의하여 인간의 모발을 연구를 돕기 위해 자동 모발 계산 시스템을 설계 및 구현 하였다. 제안하는 시스템의 접근법은 DIHAM (모발 분석 및 측정을 위한 디지털 이미지)을 기반으로 구현하였다. 우리는 모발 수의 계산을 위해 모발 이미지 세분화를 위하여 고전적인 이진 변환 방법인 Otsu threshold를 사용하고 계수를 위해 단일 모발 영역을 분리하는 것에 중점을 두었다. 또한 겹치는 모발 영역에서 단일 모발 분할을 위해 Hough 변환을 활용하였다. 제안 방법의 실험결과 성공적인 결과가 도출되었다.

광고의 모호성 이미지의 시각화 속성에 관한 연구

장천인,양재범 한국디자인리서치학회 2022 한국디자인리서치 Vol.7 No.2

The content of advertising design often gives people a sense of confusion. What is the reason for this characteristic of blurred image? From the point of view of notation, there are many reasons for Ambiguity, and the specific core elements of Ambiguity are based on 'inconsistency'. In advertising, visual information becomes the central element, so ambiguity of meaning is portrayed. In his opinion, when advertising is centered on linguistic information, the meaning is conveyed more clearly, but visual information becomes an important component of advertising, thus increasing the room for polysemy interpretation. Therefore, based on the method of case study, this study tries to find out what the visual characteristics of fuzzy images are and what formative factors affect these characteristics. From the perspectives of visual condensability, information deficiency, semantic complexity and concept divergence, 15 specific methods and various forming factors of image fuzziness are found. This study provides a practical classification item for the visualization method of Ambiguity image in advertisement. 광고 디자인의 내용은 종종 혼란스러운 느낌을 준다. 그런 이미지의 모호한 특성 원인은 무엇일까? 기호학적 관점에서 모호성을 일으키는 원인은 여러 가지이며, 모호성을 형성하는 구체적인 핵심 요소는 ‘불일치성’에 근거한다. 광고에 있어서는 시각 메시지가 중심요소를 이룸으로써 의미의 애매성이 부각된다고 보고 있다. 그에 의하면 광고가 언어적 메시지 중심일 때는 의미전달이 비교적 명확했으나 시각적 메시지가 광고의 중요한 구성요소가 됨으로써 다의적 해석의 여지를 더욱 증대시킨다는 것이다. 따라서 본 연구는 사례 연구의 방법을 바탕으로 모호한 이미지의 시각화 특성은 무엇이며, 이러한 특성들은 어떤 형성적 요인에 영향을 받았는지 알아내려고 노력한다. 시각 응축성, 정보 결핍성, 의미 혼잡성, 개념 일탈성, 네 가지 관점에서 15가지 이미지 모호성을 구현하는 구체적인 방법과 다양한 형성 요소를 발견했다. 본 연구는 광고에서 모호한 이미지의 시각화 방법에 대한 실질적인 분류항목를 제공한다.현대 사회에서 광고의 변화는 직관적인 광고에서 은유 표현으로 생긴 광고 스타일 변화에서 비롯된다. 이러한 경우에 모호성에 대한 연구는 미래 광고 시장에 대한 연구 가치가 있다고 할 수가 있다. 특히, 광고에서 모호 이미지를 시각화하는 방법은 실질적인 분류 항목을 제공할 수가 있다.
