Hyun Sang-Yoon, a teacher in Bosung School, was one of the key persons in the March First Movement. However the historical studies on his independence movement have not done much. The historical studies of the March First declaration of Korean independence were focused on the thirty three representatives, who signed the manifesto. Hyun Sang-Yoon was not the one of the thirty three representatives. His mission was one of the second leader group, who planned and led the March First Movement from behind. This study deals with his real role in the Mrch First declaration of Korean independence. He gave aid to the Korean students in Tokyo, who declared the Korean independence at 8th, February in 1919. Their declaration of Korean independence ha influence on the March First Movement in their homeland. He was the first man, who met Son Gye-Baek, a messenger of Korean students in Tokyo, and communicated the fact to the Chundogyo leaders such as Choi Rin, Kwon Dong-Jin, Oh Se-Chang and Son Byung-Hee. The March First Movement was planned and led by the religious leaders. Chundogyo, Christianity and Buddism were the big and influential organization in Japanese colonial period. These three powerful religious group joined one another for the Korean independence declaration against Japanese colonial rule. Hyun Sang-Yoon and Choi Nam-Sun communicated the Chundogyo leaders` plan of Korean independence movement to the Lee Seung Hoon, who was the influential leader of the Korean Christianity. By Hyun and Choi`s truly patriotic mediation, the cooperation between the Chundogyo leaders and the Christianity leaders was possible. Hyun Sang-Yoon wrote his memories of the March First Movement in 1946. His momories are vivid and real, so they have important historical value. The official records by Japanese colonialism do not say the facts which Korean independence leaders did not want to open to public for the fulfillment of independence movement and their friends` safe. This means that his memories have the importance as the historical evidence on the March First movement.

Sensors are applied to small aviation platforms for various purposes. Radio frequency (RF) antennas, which are representative sensors, are available in many forms but require the application of slot array RF antennas to ensure high performance and designation. Slot RF array antennas are applied to dip brazing techniques, but the yield and production time are determined by the proficiency of production personnel in a labor-intensive form. Unmanned aerial vehicles or drones, which are representative small aviation platforms, are continuously exposed to various random vibrations because propellers and multiple power sources are used in them. In this study, the fatigue life of slot array RF antennas applied with additive manufacturing was evaluated through the cumulative damage method (Miner’s rule) in a vibration environment with a small aviation platform. For the evaluation, an S–N curve obtained from a fatigue strength test was used.

김기승(Ki Seung Kim),함혜수(Hae-Soo Ham) 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.3

연구의 목적은 중학생의 방과 후 스포츠 활동 참여가 심리적 안녕감에 미치는 영향을 실증적으로 분석해 보는데 있다. 이를 위해서 충남 공주시에 있는 2개 중학교 1, 2,3 학년 학생 280명을 대상으로 설문조사를 실시하였다. 설문기간은 2019년 9월8일부터 10월 17일 까지 약 1개월 동안 실시하였다. 심리적 안정감의 측정도구는 Ryff(1995)가 개발한 척도를 사용하였다. 하위요인은 자아수용(6문항), 긍정적 대인관계(5문항), 자율성(6문항), 환경에 대한 통제력(5문항), 삶의 목적(5문항), 개인적 성장 (5문항) 등 총 32개 문항으로 Likert 5점 척도로 구성하였으며 본 연구의 내적합치도(Cronbach’s α는 .76-.83으로 나타났다. 조사대상 학생 중 52.1%인 146명이 방과 후 스포츠 활동에 참가하고 있는 것으로 나타났다. 방과 후 스포츠 활동 유무에 따른 심리적 안녕감에 미치는 영향은 참여집단이 높은 것으로 나타났으며 심리적 안녕감의 6개 하위변위 자아수용, 긍정적 대인관계, 자율성, 환경에 대한 통제력, 삶의 목적, 개인적 성장 등 모든 변인이 통계적으로 유의성이 검증되었다. 이러한 연구결과로 볼 때 중학생의 스포츠 활동은 정서의 발달에 직접적인 영향을 미친다는 강명화(2011), 김판수(2012), 등의 연구와 일치하는 것으로 나타났다. 본 연구를 통해서 확인할 수 있었던 것은 방과 후 스포츠 활동의 강화 방안을 모색하고 문제아동을 적극 참여시키는 방안을 마련할 필요가 있다. 방과후 스포츠 활동의 참여는 날로 심각해지고 있는 사회의 정화 차원에서 검토되어야 한다. The purpose of this study is to empirically analyze the effects of middle school students" participation in after-school sports on psychological well-being. A survey was conducted on 280 students in 7th, 8th, and 9th grades attending two middle schools in Gongju-si, Chungnam, for one month from September 8 to October 17, 2019. The scale developed by Ryff (1995) was used to measure psychological stability. Subfactors including self-acceptance (6 questions), positive interpersonal relationships (5 questions), autonomy (6 questions), environmental control (5 questions), purpose of life (5 questions), and personal growth (5 questions) comprised a total of 32 questions measured on the Likert 5-point scale. The internal fit score (Cronbach"s alpha) was .76-.83, with 146 students (52.1%) participating in after-school sports activities. The effect was high in the participant group. All variables, including the six subfactors, were verified statistically. These findings are consistent with the studies of Kang Myung-hwa (2011) and Kim Pan-su (2012), which reported that the sports activities of middle school students directly affect the development of emotions. This study verified the need to strengthen after-school sports activities and to engage problem children. After-school sports activities should be reviewed in the context of social issues that are becoming increasingly serious.

관성센서를 이용한 스트랩다운 탐색기 훼손영상 복원기법

김기승(Ki-Seung Kim),나성웅(Sung-Woong Ra) 한국항공우주학회 2012 韓國航空宇宙學會誌 Vol.40 No.1

본 논문에서는 스트랩다운 영상탐색기 개발을 위해 각속도계 정보를 이용한 실용적인 움직임 훼손영상 복원 필터링 기법을 제안한다. 각속도계 편향오차가 움직임 훼손을 기술하기 위한 점확산 함수 파라미터의 불확실성으로 작용한다는 점에 착안하여, 이를 놈 제한 조건을 만족하는 파라미터 불확실성으로 가정한 후 움직임 훼손 영상을 불확정 선형 상태 공간 방정식으로 모델링한다. 각속도계 편향오차에 의한 파라미터 불확실성 행렬이 놈 제한 조건을 만족한다는 가정 하에, 순환 선형 강인 칼만필터에 기반한 움직임 훼손영상 복원필터가 설계된다. 실제 IR 영상을 이용하여 제안된 영상훼손 복원 필터가 각속도계 편향 오차가 존재하는 상황에서도 신뢰할만한 영상복원 성능을 제공함을 확인한다. This paper proposes a practical linear recursive robust motion deblurring filter using the inertial sensor measurements for strapdown image seekers. The angular rate information obtained from the gyro mounted on the missile is used to define the PSF(point spread function). Since the gyro output contains a unknown but bounded bias error. the motion blur image model can be expressed as the linear uncertain system. In consequence, the motion deblurring problem can be cast into the robust Kalman filtering which provides reliable state estimates even in the presence of the parametric uncertainty due to the gyro bias. Through the computer simulations using the actual IR scenes, it is verified that the proposed algorithm guarantees the robust motion deblurring performance.

PSD를 이용한 플라스틱 박막 필름의 경사 각도 측정 시스템 개발

김기승(Gi-Seung Kim),박윤창(Yoon-Chang Park) 한국산학기술학회 2021 한국산학기술학회논문지 Vol.22 No.2

스마트폰 등에서 사용되는 고성능 디스플레이에는 다양한 종류의 정밀한 플라스틱 박막 필름(Plastic Thin Film)이 사용되고 있다. 롤투롤(Roll-To-Roll) 공정으로 제조되는 플라스틱 박막 필름은 생산 공정 중에 실시간으로 필름의 두께가 계측되고, 정확하게 관리되어야 한다. 필름 제조 과정에서 필름에 장력이 작용하면서 주름이 발생되고, 이러한 주름 발생은 필름의 두께 방향과 두께 측정기의 광축이 서로 경사지게 한다. 결국 두께 측정기는 필름의 수직두께가 아닌 경사진 두께를 측정하게 됨으로써 실제 두께보다 더 큰 값으로 측정하게 된다. 본 연구에서는, 플라스틱 필름의 경사로 인하여 발생하게 되는 두께 측정기에서의 계측값 오차를 보정하기 위하여, 필름의 경사 각도를 계측하는 연구가 진행되었다. 플라스틱 필름에 슬릿 빔 레이저를 조사하고, 필름에서 반사되는 슬릿 빔 레이저가 PSD(Position Sensitive Device)에 맺히는 광학 시스템을 구성하였으며, 실험을 통하여 필름의 경사 각도와 PSD 출력값의 관계를 1차 방정식 형태로 구하였다. 이를 이용하여 필름의 경사 각도를 측정하는 장치가 구축되었으며, 250KHz의 속도로 경사 각도의 측정이 가능하였다. Various types of precision plastic thin films are used widely in high-performance displays, such as smartphones. For plastic thin-films manufactured by the Roll-to-Roll process, the film thickness must be measured and managed while moving. In the Roll-to-Roll process, wrinkles are generated when tension is applied to the film, which causes an inclination on the optical axis of the thickness gauge, resulting in a loss of accuracy. Therefore, this study attempted to develop an optical interference tomography measurement system. In this study, the tilt angle of the film was measured to correct the measurement value error in the thickness gauge caused by the tilt of the film. The system was constructed so that the laser was irradiated on the tilted film, and the laser reflected from the film was formed on the PSD. The relationship between the tilt angle of the film and the output value of the PSD was obtained experimentally. Using this, a device to measure the tilt angle of the film was constructed, and angle measurements were taken at a speed of 250,000Hz.

The purpose of this study is to find the structural relationship and influence between Myongri occupational apriority, career resilience and career decision level, and to verify the mediation effect of career resilience and moderation effect of satisfaction on career choice. A structuralized survey was conducted on 360 undergraduate students on their 4th year, and the results were analyzed using AMOS 18.0 statistical program to verify the study problem through structural equation model. As a result, C.R. value was above 2.58 for all paths except ‘Myongri occupational apriority → career decision level’, showing significance at 1% significance level. Looking into standardization coefficient of significant paths in paths among latent variables, path coefficient was 0.449 for ‘Myongri occupational apriority → career resilience’ and 0.971 for ‘career resilience → career decision level’, showing significance at 1% significance level. Accordingly in this study, the significance of indirect effects and total effects, and the effects of path coefficient among latent variables were disintegrated. As a result, Myongri occupational apriority has direct effect of 0.449 on career resilience. Myongri occupational apriority does not have significant direct effect on career decision level and only has indirect effect of 0.436. In other words, Myongri occupational apriority can have direct effect on career decision level via career resilience, and it is mediated by career resilience to affect career behavior and performance. Also, all of such indirect paths are significant. Career resilience has direct effect of 0.917 on career decision level, and this can be interpreted as to mean that increase of career resilience can directly facilitate improvement of career decision level. In addition, as a result of verifying moderation effect of satisfaction on career choice, the difference in path coefficient between group with high satisfaction on career choice and group with low satisfaction on career choice was found to be statistically significant. Since the group with higher level of satisfaction on career choice has higher path coefficient, Myongri occupational apriority was found to reinforce career decision level through satisfaction on career choice. Additionally, when the influence of 3 dimensions of Myongri occupational apriority including goal orientation, utilization value, and interest and passion was determined using multiple regression analysis, their influence on career decision level was shown in the order of interest and passion, goal orientation, and utilization value. In the end, career resilience was confirmed to show complete mediation of the relationship between Myongri occupational apriority and career decision level. Therefore, it would be reasonable to decide career based on ability, but interest and passion was found to play an important role in realizing resilient career attitude and enthusiastic career decision for occupational success.

『자평진전』, 『적천수』의 부·귀 해석체계 특징 고찰

김승종 ( Seung-Jong Kim ),김기승 ( Ki-seung Kim ) 산업진흥원 2021 산업진흥연구 Vol.6 No.3

본 논문의 목적은 『자평진전』과 『적천수』의 부·귀 해석체계 특징에 대하여 고찰해보는 것이다. 명리학은 인간의 부귀(富貴)에 대한 탐구에서 시작된 학문이다. 명리학의 2대 고전으로 『자평진전』과 『적천수』가 있다. 그런데 이러한 대표 저서가 부귀해석에 대한 해석체계에서 서로 비슷한 점도 있지만 다른 면모도 있다. 이를 살펴보면 다음과 같다. 『자평진전』에서는 먼저 그 사주의 성패(成敗)를 판단한다. 성격(成格)이면 길(吉)한 사주가 되고, 패격(敗格)이면 흉(凶)한 사주가 된다. 성격이 되더라도 그 중에 귀격(貴格)이 있고 대귀격(大貴格)도 있다. 대표 대귀격에는 재인병투(財印並透), 식신생재(食神生財), 식신합살(食神合煞), 살용식재(煞用食制), 상관용관(傷官用官)이 있다. 『적천수』에서 부(富)가 있는 사주로는 재기통문(財氣通門)이 있고 귀(貴)가 있는 사주로는 관성이회(官星理會)가 있다. 한국의 대표 재벌인 현대그룹 정주영회장은 『자평진전』의 논법으론 성격이 되고 식신생재격이며 『적천수』 논법으론 재기통문의 첫 번째, 세 번째, 일곱 번째 조건과 부합된다. 삼성그룹 이병철 회장은 『자평진전』의 논법으론 성격이 되고 살용식제격이며, 『적천수』 논법으론 선명한 일곱 번째 조건에 부합된다. 본 연구에서는 그러한 두 고전의 부귀에 대해 어떤 해석방법이 있는지, 어떻게 다른지 고전 원문을 통해 알아보고, 아울러, 이론적 구성의 적합성을 현대 대표 인물의 실증적 사례를 통해 부·귀 해석체계 특징을 비교 고찰을 통하여 향후 관련 연구에 조금이나마 도움이 되었으면 한다. The purpose of this paper is to examine the characteristics of the rich and noble interpretation system of 『Japyeongjinjeon』 and 『Jeokcheonsu』. Myungrihak is a study that began with the study of human wealth and nobility There are 『Japyeongjinjeon』 and 『Jeokcheonsu』 as two major classics of Myeongrihak. However, while these representative books are similar to each other in the interpretation system for the interpretation of wealth and nobility, they also have different aspects. Looking at this. In 『Jepyeong Jinjeon』, the success or failure of the Su-Ju is judged first. If it is Seong-Gyeog (成格), it becomes a good Su-ju (吉), and if it is a Pae-Gyeog (敗格), it becomes a bad Sa-Ju (凶). Even when it comes to Seong-Gyeog, among them there are Gui-Gyeong (貴格) and great Gui-Gyeong (大貴格). Representative great Gui-Gyeong include Jaein-Byeongtu (財印並透), Sigsin -Saengjae (食神生財), Sigsin-Hapsal (食神合煞), Sal-yongsigje (煞用食制) and Sanggwan-Yonggwan (傷官用官). In 『Jeokcheonsu』, there is Jaegi-tongmun (財氣通門) as a Su-Ju with wealth and Gwanseong-Ihoe as a Su-Ju with nobility (貴). Hyundai Group Chairman Chung Ju-young, the representative chaebol of Korea, becomes a Seong-Gyeog in the argument of Japyeong Jinjeon』 and is a Sigsin -Saengjae, and Jaegi-tongmun according to the argument of 『Jeokcheonsu』are met The first, third, and seventh conditions. Samsung Group Chairman Lee Byung-cheol meets the seventh condition clearly in the argument of 『Jeepyeong Jinjeon』, which is Seong-Gyeog and Sal-yongsigje. In this study, we find out what kind of interpretation method there are and how they differ from the two classics through the original text. In addition, the suitability of the theoretical composition is examined by comparing and examining the characteristics of the rich and noble interpretation system through empirical examples of modern representatives. It is hoped that it will be of some help to related research in the future.
