朴正一(Park Jung-Il) 동북아시아문화학회 2009 동북아 문화연구 Vol.1 No.21

As a result of having considered the magazine name of the women's magazine of Taisho period, I was able to discover various characteristics. For example. There is overwhelmingly much use of the kanji word with 98 examples (68%) by the magazine name. Meanwhile, there is the use of the katakana word of foreign origin for letter notation such as "woman thyme", and I diversify lexically, and there being it is thought about with influence by the character of the Taisho democracy. In addition, as for the factor that accelerated the birth of the girl magazine, that interest for the home training rose that woman education was begun is raised on a national scale. The example only for an example has sum total 109 examples (75%), and there is variety of the magazine name. I understand that the magazine name which is the symbol of the women's magazine has been regarded as important by state of things. Many magazines were launched for Taisho period, and it was ceased to publish again. A new magazine name appeared in the degree, but thinks the magazine name to be have been reflection of the times of the Taisho democracy. The figure which finished a new Japanese image for women reflected it conspicuously in the world of the women's magazine.

박정일(Park Jung Il),박민호(Park Min Ho),임이택(Lim Ri Teak) 한국지적정보학회 2010 한국지적정보학회 학술발표대회 논문집 Vol.2010 No.11

신ㆍ재생에너지는 오염원이 없는 천연에너지다. 오늘날 에너지 가격의 급등과 지구 온난화에 대비하기 위해 각국은 에너지 효율화와 절약, 원자력발전소의 증설, 신재생에너지의 개발과 보급 확대 정책 등을 추진하고 있다. 신재생에너지의 개발과 투자 못지않게 중요한 것이 발전 효율성이다. 신재생에너지는 초기 설비 투자비용이 많이 소요되는 것이 단점인데, 장기적으로 투자비용 이상의 에너지를 생산해 낼 수 있어야 한다. 신재생에너지의 대부분이 청정연료인 자연을 이용하고 있는 것이 많기 때문에 자연 환경적인 요인이 많이 작용하게 된다. 본 연구는 다양한 신재생에너지 중 지형요인 및 기후요인과 관련이 높은 태양광, 풍력의 입지 선정에 초점을 맞추어 입지 요인 선정, 기준 수립, 적지분석에 이르기까지 GIS를 활용하는 과정에 대하여 연구하고, 적용하고자 하였다. New renewable energy is the natural source energy without pollution. Recently, the necessity new renewable energy is emerging since of less green hose gas emissions. However, a survey or research on the new renewable energy system has been hardly performed. It’s not easy to find a appropriate location in consideration of environment. In this study, we intended to analyze the spatial equity and distribution characteristics of new renewable energy and to select several potential facility sites required in the study area using GIS’s spatial analysis functions. Finally this study analyzes the possible location of the new renewable energy in terms of objective criteria and Spatial Correlation Analysis techniques.

Speed Controller Design of a Two-Inertia Motor System Using Weighted ITAE Index

박정일(Jung-Il Park) 제어로봇시스템학회 2009 제어·로봇·시스템학회 논문지 Vol.15 No.6

In a two-inertia motor system with flexible shaft, a torsional vibration is often generated as a quick speed response is required. This vibration makes it difficult to achieve a quick response of speed and disturbance rejection. The objective of this paper is to provide a systematic analysis and design of the three kinds of speed controllers such as I-P, I-PD, and state feedback control by using the weighted ITAE performance index. Some simulation and experiment results verify the effectiveness of the proposed design.

KOSPI 개별기업들의 환노출과 금리노출

박정일 ( Jung Il Park ),장병기 ( Byoung Ky Chang ) 한국경제통상학회(구 한국경상학회,한국국민경제학회) 2013 경제연구 Vol.31 No.2

본 연구는 환노출퍼즐에 대한 재고찰과 함께 금리노출을 분석하기 위하여 OLS, EGARCH-M-GED, 지연효과를 고려한 EGARCH-M-GED 등 3가지 모형을 이용하여 환노출과 금리노출을 추정하였다. 또한 환노출과 금리노출의 영향요인을 확인하기 위하여 기존 연구에서 흔히 사용한 2단계 추정법 외에도 System SUR를 적용하여 비교분석하였다. 분석결과에 따르면 외환위기 이후에 환노출 기업 및 금리노출 기업의 수가 상당히 증가하였으며 외환위기 전에는 양의 환노출 기업이 많았으나 외환위기 이후에는 음의 환노출 기업이 압도적으로 많아졌다. 외환위기 이전에는 수출비중이 환노출 계수와 무관하였으나 외환위기 이후에는 수출비중이 환노출 계수에 유의한 정(+)의 영향을 주었다. 한편, 외환위기 이전에는 부채비율이 금리노출계수와 무관하였으나 외환위기 이후에는 부채비율이 금리노출계수에 유의한 부(-)의 영향을 주는 것으로 나타났다. 이는 외환위기 이후 주식시장이 보다 정보 효율적으로 바뀌었기 때문일 것이다 The main purpose of this study is to identify the exchange rate exposure and interest rate exposure of KOSPI firms and analyze the effect factors of the exposures. To investigate the exposures OLS, EGARCH-M-GED, and EGARCH-M-GED with delay effect were employed. In the meantime, for an analysis of effect factors, System SUR method as well as 2-step method was performed. We find that the number of the firms with exchange rate exposure and interest rate exposure greatly increased after the Korean financial crisis. Futhermore, in the case of exchange rate exposure, its influence changed from a positive to a negative after the Korean financial crisis. In the case of the influence of export share on exchange rate exposure and of debt ratio on interest rate exposure, there were no significant results in the period before the Korea financial crisis, but most models showed significant results in the period after the Korean financial crisis. This means that the market reflects microscopic information more efficiently after the crisis

박정일(Park, Jung il) 한국지적정보학회 2021 한국지적정보학회지 Vol.23 No.1

석면은 발암물질로서 악성중피종 등 인체에 치명적인 질병을 일으키는 물질이며, 주로 슬레이트에 다량 함유되어 있다. 지금까지는 석면이 포함된 슬레이트 지붕에 대한 조사를 주로 인간의 현장 조사에 의존해 왔으나 본 연구는 UAV(무인항공기)를 이용하여 즉각적인 조사를 지원하기 위해 시도되었다. 실험은 UAV를 이용하여 영상을 취득하고 기초자료를 생성한 후, Feature Extraction 기법으로 슬레이트 지붕 객체를 추출하고, 분류된 객체의 정확도를 평가하는 방식으로 진행하였다. 객체 분류 정확도를 평가한 결과, 전체 457개 건물 중 438개 건물이 정확하게 분류되었으며, 이는 95.8%의 정확도로 Feature Extraction 기법을 이용한 슬레이트 객체 추출방법이 유용함을 알 수 있었다. Asbestos is a carcinogen that causes fatal diseases such as malignant mesothelioma, and is mainly contained in slate in large quantities. Until now, investigations on slate roofs containing asbestos have been mainly conducted by reliance on human field investigations. This study was attempted to support immediate investigation using UAV (unmanned aerial vehicle). In the experiment, images were acquired using UAV, and basic data were generated, and then the slate roof object was extracted using the feature extraction technique. As a result of evaluating the accuracy of object classification, 438 of the total 457 buildings were accurately classified with an accuracy of 95.8%. This study indicates that the slate object extraction method using the feature extraction technique is useful.

박정일(Park, Jung il),이문석(Lee, Mun seok),최승영(Choi, Seung Young) 한국지적정보학회 2021 한국지적정보학회지 Vol.23 No.2

본 연구는 적시성 있는 소나무재선충병 피해의심목 판독을 위해 무인항공영상을 이용하였다. 연구방법은 소나무재선충병 피해목의 광학적·형태적 패턴을 이용하여 피해의심목을 추출하고, 판독의 정확도를 분석하는 방법으로 진행되었다. 연구 결과 피해고사목에 대한 적중률은 82%로 나타났다. 재선충 피해의심목의 효과적인 조사를 위해서는 작업자의 판별 능력이 매우 중요하다. 그러나 피해의심목 판독 업무가 분석자의 개별적 판단에 의하는 것은 한계가 있다. 따라서 빅데이터와 인공지능기술을 적용한 영상분석 방식을 통해 객체를 식별하는 연구가 필요하다. In this study, unmanned aerial images were used to timely analyze suspected trees damaged by pine wilt disease. Suspected trees were extracted using optical and morphological patterns of trees damaged by pine wilt disease, and the accuracy of reading was studied. As a result of the study, the accuracy ratio of the damaged tree was 82%. For effective investigation of suspected wilt worm damage, the ability of workers to identify is very important. However, it is a limit to relying on the analyst"s judgment for the task of analyzing the suspected damage tree. Therefore, there is a need for research to identify objects through image analysis methods that apply big data and artificial intelligence technology.

20世紀開港期釜山の市街地の研究

朴正一(Park Jung-Il) 동북아시아문화학회 2011 동북아 문화연구 Vol.1 No.29

As a result of having considered the city area of the Japanese leased territory of Pusan I obtained the result such as the result next which I analyzed mainly on an ancient map of Pusan about open Korea period of Pusan. was enforced by a top‐down method by the then Japanese Government. I think that the form of the town is based on city structure and a grid in succession to the descent from Japanese castle town and was formed. Of course there is neither the castle nor the castle tower, but, on the other hand, I establish stem mountain god Corporation in the top of the mountain behind of the central exclusive management of the city in Japan and do it with a psychological centripetal tendency place, and the street in the city does the form of the straight line basic tone for strategic defensive purposes there not a way seen in the neighborhood of the existing Torai prefecture which there was in the neighboring. In addition, what the dark factory of the objective hue of the military demand posts you in the safe place of the city, and locate a Japanese mounting a horse corps in the border with an outside Settlement territory thinks that there is a clearly strategic intention. In addition, I am big, and the existing city area en larges even a mask of the mass on the scale with a merger on later Korea day, and combination of sea power and the land power is completed as a point binding a sea route and a land route together than the defensive purpose, but it is aimed for the military strategy that is going to enlarge penetration in the continent via a peninsula. The city area gradually understands what deepened the density ad s a place of the life of people to live in there as a point transporting such military and supplies while spreading.
