네트워크 중심전에서 C4I체계의 안정적 운용을 통한 전장에서의 정보우위 달성을 위해 체계의 신뢰성 확보가 필요하여 각 군C4I체계는 외주 용역업체를 통해 유지보수를 수행 중에 있다. 유지보수는 C4I체계의 수명 주기 중 가장 오랜 기간을 차지하고 있으며 결함 데이터 등의 실증적인 자료를 확보할 수 있는 기간이다. 따라서 유지보수 기간 중 수집한 결함 데이터를 결함분석 기법을 통해 분석(치명도, 발생빈도)하고, 주요기능별 활용도를 이용하여 C4I체계 유지보수 관리 우선순위 선정기법을 제안한다. 이 후 제안 기법을 해군 C4I체계의 군적용 사례연구를 통해 유지보수 관리 우선순위를 선정함으로써 유지보수의 제한된 자원(예산, 인력, 시간 등)을 효율적으로 활용하기 위한 판단의 근거로 사용이 가능함을 보인다. 뿐만 아니라 체계화된 결함분석과정을 통해 축적된 자료를 활용하여 유지보수의 연속성 보장과 향후 성능개량사업간 시스템 분석의 참고자료로 활용함에 따라 궁극적으로 C4I체계의 신뢰성을 향상시킬 수 있다.

김기왕 ( Kiwang Kim ) 대한한의진단학회 2010 大韓韓醫診斷學會誌 Vol.14 No.1

Objectives : To qualify or enhance the diagnostic ability of students in Oriental Medicine, so called standardized patients are ideal modality, but because it`s a man-based method, more convenient tools are required. Computer-based diagnostic ability test program gives effective way for the very purpose. So we made a pilot software evaluating Pattern Identification ability in Oriental Medicine. Methods and Materials : The pilot software was coded with Microsoft`s EXCEL VBA. 87 names of Zheng (Symptom Pattern) and 674 names of symptom (including some signs) are adopted from the former standardization works conducted by Korean Institute of Oriental Medicine (KIOM) in 1996. Results : Compared with some manned modalities to test Pattern Identification ability, the test by this software shows superiority in convenience and objectivity. Conclusion : This software is world`s first program to perform computer-based evaluation of Pattern Identification in Oriental Medicine, and it gives effective way to complement both written test and manned clinical performance test (CPX).

촬상소자를 이용한 맥동의 2차원 계측

김기왕 ( Kiwang Kim ) 대한한의진단학회 2008 大韓韓醫診斷學會誌 Vol.12 No.2

Objectives: For the traditional pulse diagnosis in Oriental Medicine, not only the pulse shape in time domain, but the width, length and depth of arterial pulse also should be measured. However, conventional pulse diagnostic systems have failed to measure the spatial parameters of the arterial pulse e.g. effective length of arterial pulse in the wrist. In fact, there are many ways to measure that kind of spatial features in arterial pulsation, but among them, the method using image sensor provides relatively cheap and simple way, therefore I tested feasibility of measuring 2-dimensional pressure distribution by imaging devices. Methods: Using widely used PC cameras and dotted balloons, the subtle oscillation of skin over the radial artery was recorded continuously, and then the displacement of every dot was calculated. Consequently, the time course of that displacements shows arterial pulse wave. Results: By the proposed method I could get pressure distribution map with 30Hz sampling rate, 21steps quantization resolution, and approximately 1mm spatial resolution. With reduced quantization resolution, 3cm×4cm view angle could be achieved. Conclusion: Although this method has some limitations, it would be useful method for detecting 2-dimensional features of arterial pulse, and accordingly, this method provides a novel way to detect `narrow pulse`, `wide pulse`, `long pulse`, `short pulse`, and their derivatives.

황제내경의 저자들은 어떤 질병을 고칠 수 없었는가 : 황제내경의 불치증에 대한 고찰

김기왕(Kim Kiwang) 대한한의학원전학회 2021 대한한의학원전학회지 Vol.34 No.1

Objectives : This paper aims to examine situations that were conceived as incurable at the time of publication of the Huangdineijing. Methods : The texts of the Huangdineijing were searched for contents which included cannot be cured. Next, the verses were examined within their context, after which those that specifically indicated incurability were selected. These were categorized according to content, then organized to better show the situations that were seen as incurable to the authors of the Huangdineijing. Results : The conditions deemed incurable in the Huangdineijing were bloody and purulent stool, ascites, tumors, some purulent inflammation, some infectious diseases with fever, wasting thirst, chronic kidney disorder, some diseases of the connective tissue, epilepsy, cardiac infarction, and cerebrovascular diseases. Internal damage due to acupuncture and poor patient attitude could also contribute to incurability. Conclusions : The authors of the Huangdineijing were unable to cure some conditions that are currently being cured by Korean Medicine.

고대 진단법 `기해술(奇咳術)`의 복원

김기왕 ( Kiwang Kim ) 대한한의진단학회 2009 大韓韓醫診斷學會誌 Vol.13 No.2

Objectives: Huangdineijing, the major classic of Oriental Medicine, preserves several precedent diagnostic classics and it`s methods. Qihaishu (奇咳術), is a name of such classic, and the name of it`s essential method at the same time. Up to now, the whole features of that method has not been unveiled. In the present thesis, I presented some clues to figure out the method - Qihaishu. Methods: By comparison of some articles in Canggongliechuan (in Shiji) (史記倉公列傳) to those of Huangdineijing Suwen (黃帝內經素問), I reconstructed the diagnostic steps of Qihaishu. Results: It was proved that Qihaishu method was carried by comparison of left and right arterial pulse under the Wuxing (五行) context. Conclusion: Qihaishu is not a set of knowledge describing the features of diseases, but a pulse palpation method to get prognosises.

고문헌 벽자(僻字) 입력을 위한 한자 자형 부호화 방법

김기왕 ( Kim Kiwang ) 대한한의학원전학회(구 대한원전의사학회) 2019 대한한의학원전학회지 Vol.32 No.1

Objectives : There are many secluded Chinese characters - so called Byeokja (僻字) in ancient classic literature, and Chinese characters that are not registered in Unicode and Variant characters (heterogeneous characters) that cannot be found in the current font sets often appear. In order to register all possible Chinese characters including such characters as units of information exchange, this study attempts to propose a method to encode the morphological information of Chinese characters according to certain rules. Methods : This study suggests the methods to encode the connection between the nodules constituting the Chinese character and the coordinates of the nodules. In addition to that, rules for expressing information about curves, expressions of aspect ratios of characters, rules for minimizing coordinate lines, and rules for expressing aggregation status of character components are added. Results : Through the proposed method, it is possible to generate codes of a certain length by extracting only information expressing the morphological configuration of characters. Conclusions : The method of character encoding proposed in this study can be used to distinguish variant characters with small variations in Byeokja, new Chinese characters and character strokes and to store and search them.

C4I Maintenance Priority Decision using Maintenance Metric

Kiwang Kim(김기왕),Dongsu Kang(강동수) 한국컴퓨터정보학회 2017 韓國컴퓨터情報學會論文誌 Vol.22 No.12

Systemic management is required at each phase of the C4I system life cycle to achieve information advantage in the battlefield through stable operation of the C4I system under the NCOE. In particular, the maintenance phase is the longest period of the C4I system life cycle, and it is easy to utilize and analyze data such as faults that occur during system operation. However, according to the previous research, the maintenance is evaluated as a phase in which the definition and management of comprehensive indicators are insufficient compared to other phase. In this paper, we propose the method of C4I Maintenance Priority decision using Maintenance metric. As a result of modifying the Naval Tactical C4I System"s preventive maintenance cycle according to the priority, the total number of faults is reduced and the maintenance efficiency is improved.

현대 증(證) 정의의 역사 -20세기 중국의 문헌을 중심으로-

김기왕,Kim, Kiwang 대한한의진단학회 2016 大韓韓醫診斷學會誌 Vol.20 No.1

Objectives Although the word Zheng (證) is widely used basic term in nowaday's East Asian traditional medicine, it's definition can't be found in ancient texts before 20th century, and the history in which that term got general meaning in public, have not been clearly introduced. So the present author show the way Zheng confirm it's modern implication. Methods To search the books that contain any contents on Zheng's definition, the author mainly used the electronic texts of Super Star Reader (超星閱讀器). To search modern study article on Zheng's definition, the author used China National Knowledge Infrastructure (www.cnki.net). Results The present study shows that : although Treatments according to disease Pattern Identification (辨證施治) have been prominent treatment modality in East Asian traditional medicine, the general definition of disease Pattern (證) was given in late 20th century. Especially from 1955 to 1965, some major scholars like Ren Ying Qiu (任應秋), Zhu Yan (朱顔), Qin Bo Wei (秦伯未) and Jiang Jian Fu (蔣見復) did important roles in it's concept creation. Conclusions Modern concept of Zheng (證) was defined in late 20th century.

고인들은 1분에 9회 빈도의 호흡을 하였는가? : "일만삼천오백식(一萬三千五白息)"에 대한 고찰

김기왕,Kim, Kiwang 대한한의진단학회 2017 大韓韓醫診斷學會誌 Vol.21 No.1

Objectives Some major Chinese medical classics like Huangdineijing (黃帝內經) and Nanjing (難經) assert that a normal person breaths 13,500 times every day. It's just half of real breathing cycles of human. So I tried to find a reasonable explanation to solve this conflict between truth and literal description. Materials and methods To find breath count descriptions in Chinese ancient books, I used Kanseki Repository (http://kanripo.org/). To find precedent research on this topic, I used China National Knowledge Infrastructure (http://cnki.net). Results 33 books refers to human breath cycles for a day, and most of them introduce 13,500 as human breathing frequency of one day. Some recent papers on Laoguanshan (老官山) Western Han dynasty manuscripts show new clues on this topic. Conclusion I assume that 13,500 cycles, the incorrect human breathing frequency of a day, might be originated from adjusting the meaning and usage of the word "Xi (息)".

김창희 ( Changhee Kim ),김기왕 ( Kiwang Kim ) 대한한의진단학회 2013 大韓韓醫診斷學會誌 Vol.17 No.3

Objectives Although tongue diagnosis is one of major diagnostic methods in east Asian traditional medicine, the standard of normal tongue color have not established. So we tried to suggest the method to establish the standard of normal tongue color range and the pilot data about the normal range. Materials and methods: 22 precedent study papers that presented the numerical data of normal (light red) tongue color were analyzed. At the same time, 46 adult people tongue color data were also collected and analyzed. Results Precedent studies showed remarkable fluctuations of the range of normal tongue color. Collected tongue color data of the 46 people showed mean Hue value 2 and standard deviation 14 in HSB system. Additionally, 3 ways of standard establishment for normal tongue color were suggested. Conclusion We suggest statistical method as a reasonable method for tongue color standard establishment and 2±14 as a reference Hue value for normal tongue color.
