        모유수유 실태에 관한 조사연구 : 경상북도성주군을 중심으로

        박천만,김규종,이종렬,김혜진 韓國保健敎育.健康增進學會 2000 보건교육건강증진학회지 Vol.17 No.1

        This study to study and analyze the current state of infancy breast-feeding & practice and related factors and to provide basic data for the effective practice of breast-feeding and breast-feeding percentage improvement. For the object, 474 mothers of the infants who were born between Jan. 1, 1998 and Dec. 31, 1998 were selected, and the survey period & method were from Oct. 15, 1999 through Nov. 14, 1999(1 month period) and telephone interview, respectively. To examine by monthly breast-feeding type, the average breast-feeding percentage in 1 month after a child's birth was 42.4%, but after 6 month it decreased to 23.0%. To see breast-feeding percentage by academic background, the breast-feeding of elementary school graduated mothers was 33.3%, which was highest, and it decreased as the academic background of mothers went better(p〈0.01). By employment state the percentage for the mothers who were not employed was higher(24.6%) than that of those who were employed at the time, which was 8.0%(p〈0.001). There was no meaningful difference found in breast-feeding percentage by infant mothers age, delivery place, infant sex, child order in family, weight at the time of birth. To examine breast-feeding percentage by delivery method, natural delivery was 27.0% which was higher that 13.1% of Caesarean section(p〈0.01), and by breast-feeding experience before leaving the hospital, 35.6% of those who have breast-fed were breast-feeding while it was 16.4% for those who never did it while in the hospital(p〈0.001) After conducting logistics multi return analysis having breast-feeding percentage as a variable at the time of 6 months after babys birth, I found that infant mothers employment state, delivery method, and brest-feeding experience before leaving the hospital become meaningful variables. As unemployed mothers(p〈0.05), as chose natural delivery(p〈0.05), as experienced breast-feeding before leaving the hospital(p〈0.001), there was more tendency to do breast-feeding. Summing the above results, I would like to suggest the following to raise breast-feeding percentage. Firstly, systematic education about the importance and advantages of breast-feeding and correct breast-feeding method should be practised for women. Secondly, vacation before and after childbirth for working women should be practised and the support of systems for working womens breast-feeding such as installation of nursery in work place are needed. Thirdly, continuous publicity and education for natural delivery inducement is necessary, and for the ones who chose Caesarean section, recommendation of breast-feeding is also needed. Fourth, for breast-feeding within fastest time after delivery, rooming-in required and legal and systematic support is also needed. Lastly, in the governmental level, publicity for breast-feeding and breast-feeding recommending programs that promotes 10 rules for successful breast-feeding bringing-up, provided by UNISEF and WHO, are to be provided.

        Aerial Object Detection and Tracking based on Fusion of Vision and Lidar Sensors using Kalman Filter for UAV

        박천만,이성봉,김혜지,이동진 한국인터넷방송통신학회 2020 Journal of Advanced Smart Convergence Vol.9 No.3

        In this paper, we study on aerial objects detection and position estimation algorithm for the safety of UAV that flight in BVLOS. We use the vision sensor and LiDAR to detect objects. We use YOLOv2 architecture based on CNN to detect objects on a 2D image. Additionally we use a clustering method to detect objects on point cloud data acquired from LiDAR. When a single sensor used, detection rate can be degraded in a specific situation depending on the characteristics of sensor. If the result of the detection algorithm using a single sensor is absent or false, we need to complement the detection accuracy. In order to complement the accuracy of detection algorithm based on a single sensor, we use the Kalman filter. And we fused the results of a single sensor to improve detection accuracy. We estimate the 3D position of the object using the pixel position of the object and distance measured to LiDAR. We verified the performance of proposed fusion algorithm by performing the simulation using the Gazebo simulator.

        新羅 加耶古墳의 曆年代

        박천수(朴天秀) 한국상고사학회 2010 한국상고사학보 Vol.69 No.-

        본 연구는 고분의 曆연대에 대해 100년 이상의 연대폭을 보이는 등 심각한 견해차를 노정되고 있는 신라 가야고분의 역연대를 구축하는 것을 목적으로 하였다. 먼저 연구사를 검토하고 피장자의 추정이 가능한 고구려 태왕릉 출토 마구, 기년명을 가진 중국제 도자기와 공반된 백제마구, 일본열도의 연륜연대 자료 등을 통하여 한일고분의 교차편년의 기준이 되는 경주시 황남동 109호분3.4곽.부산시 복천동21.22호분.大阪府大庭寺TG232窯, 황남대총 남분, 합천군 옥전M3호분.埼玉縣稻荷山古墳의 역연대를 중심으로 논의하였다. 그리고 역연대에 대한 논의를 기반으로 종래 역사적 사건과 연계하여 역연대를 도출하고 이에 따른 해석에 대한 재검토를 실시하였다. 그 결과 황남동109호분3.4곽, 복천동21.22호분, 大庭寺TG232窯은 4세기 말, 황남대총 남분은 5세기 중엽, 옥전M3호분, 稻荷山古墳은 5세기 후엽으로 그 역연대가 설정되었다. 이는 역연대의 기준이 되는 3者가 모순 없이 整合성을 보여주는 점에서 신뢰성이 높은 것으로 판단된다. 부산시 복천동21.22호분을 5세기 중엽으로 보는 연대관은 400년 전후 광개토왕의 남정을 지나치게 의식한 것이며, 이는 신라의 영향력이 부산지역에 미친 시기를 늦추어 보고 이 지역의 독자성을 강조하려는 의도에 의한 것이다. 한편 황남동109호분3.4곽을 4세기 중엽으로 보고, 황남대총 남분을 5세기 초로 보는 견해는 신라의 성장을 과대평가한 것으로 판단된다. 이와 마찬가지로 기마민족이 김해지역으로 이주하고 또한 다시 일본열도와 영남내륙지역으로 이동하였다는 주장은 그 실제성과 해석의 방법론적 문제뿐만 아니라 그 근거로 제시한 역연대가 전혀 일치하지 않는 점에서 역사적 사실로 볼 수 없음을 분명히 하고자한다. 본고에서는 역사적 맥락에 의해 선험적으로 역연대를 결정하는 것을 止揚하고, 고고자료의 분석에 기초한 객관적인 역연대의 구축을 지향하고자 노력하였다. 이를 통하여 역사 해석의 합리적인 시간축이 제공될 것으로 본다. The purpose of this study is to establish absolute date of Shilla Gaya tombs which show serious differences of opinions about historical absolute date of tombs over more than 100 years. First research history was reviewed and through excavated harness of Goguryeo King Tae’s tomb which can estimate the period of buried person, Chinese porcelains with records of names of years, excavated Baekje harness, growth ring chronicle data of Japanese archipelago for absolute date of the third/fourth gravers of tomb No.109 at Hwangnam–Dong in Gyeongju city, the gravers of tomb No.21/22 at Bokcheon–Dong in Busan city, Obdera TG232 Kiln in Osaka Prefecture, South tomb of Hwangnam Great Tomb, the graver of tomb Okjeon No.M3 in Habcheon–Gun and Inariyama tomb in Saitama Prefecture, which all become the standard of crossing dating of Korean & Japanese tombs were mainly reviewed and discussed. And based on discussion of absolute date were induced in connection to the historical events of the past and re–review of historical interpretation was conducted. As the result, absolute date of the third/fourth gravers of tomb No.109 at Hwangnam–Dong, the gravers of tomb No.21/22 at Bokcheon–Dong and Obdera TG232 Kiln was set as the end of the 4th century, absolute date of Hwangnam Great Tomb was set as the middle of the 5th century and the graver of tomb Okjeon No.M3 and Inariyama tomb was set as late period of the 5th century. It is judged to have higher reliability because all three parties, which become the standard of absolute date, show conformity without contradiction. Opinion of absolute date of the gravers of tomb No.21/22 at Bokcheon–Dong around the middle of the 5th century is from too much consciousness of the expedition to the south of Great King Gwanggaeto around the year of 400 and it was intended to emphasize identity of this region by postponing the period of influence of Shilla on Busan region. On the other hand, opinions of regarding the third/fourth gravers of tomb No.109 at Hwangnam–Dong as the middle of the 4th century and south tomb of Hwangnam Great Tomb as the early part of the 5th century are judged that growth of Shilla was overestimated. Just like this, I would like to make it clear that we cannot recognize insistence that horse–riding people moved into Gimhae region and also again moved to Japanese archipelago and inland region of Yeongnam as historical events since not only issues of its reality and methodology of interpretation but also absolute date suggested as the ground are not conforming at all. In this thesis, establishment of objective absolute date based on analysis of archaeological data was pursued by sublating deciding absolute date in transcendental experience by historical logical connection. It is believed that reasonable axle of time of interpretation of the history will be provided through this

        외국인 유학생의 학업스트레스와 우울과의 관계에서 자아존중감의 매개효과

        박천만 한국학교ㆍ지역보건교육학회 2022 한국학교지역보건교육학회지 Vol.23 No.2

        Objectives: The purpose of this study was to examine the mediating effect of self-esteem on the relationship between academic stress and depression in foreign students in Korea. Methods: The subjects of this study were 343 foreign students enrolled in universities and graduate schools in Daegu and Gyeongbuk area, and data were collected by conducting a questionnaire survey using the internet. The collected data was analyzed using SPSS 23.0 and PROCESS macro Model No 4. Results: The results were as follows. First, academic stress of foreign students increased the level of depression statistically significantly. Second, academic stress significantly reduced the self-esteem of foreign students. Third, the self-esteem of foreign students partially mediated the effect of academic stress on depression (p<0.05). In other words, it suggests that academic stress lowered self-esteem, and that the lowered self-esteem had an effect on the increase in depression. Conclusions: These results suggest that an intervention program to reduce academic stress is needed as a countermeasure for the alleviation and prevention of depression in foreign students, and that strategies for improving self-esteem should be considered as important. .
