박동진,이상화,박상호,김창진,Park, Dong-Jin,Lee, Sang-Hwa,Park, Sang Ho,Kim, Chang-Jin 한국미생물학회 1998 미생물학회지 Vol.34 No.3

산림, 밭, 초지, 논 토양의 두 깊이(0~2cm, $50{\pm}1cm$)에서 계절별로 채취한 토양 시료로부터 서로 다른 방선균주를 분리, 동정하여 계절별 토양 방선균의 속 다양성을 조사하였다. 토양 표층에 분포하는 Streptomyces속 방선균주의 계절별 변동율은 논(18%)과 산림(18%) 토양에 비해 초지(41%)와 밭(39%) 토양에서 더 높게 나타났으며 $50{\pm}1cm$깊이에서는 논(36%), 밭(28%), 초지(26%), 산림(16%) 토양 순으로 높게 나타났다. 한편 희소 방선균의 계절별 분포 변동율을 토양 표층의 경우 논 토양(26%)을 제외하고는 모두 45%이상이었으나 $50{\pm}1cm$깊이에서는 산림(79%), 논(36%), 밭(24%), 초지(10%) 토양 순으로 높게 나타났다. 따라서, 토양 중에 분포하는 방선균의 속 다양성은 계절 변화에 의지하며 또한 이는 방선균군의 종류, 토양의 유형, 그리고 토양 깊이에 의해서 영향을 받을 것으로 고려된다. From soils seasonally collected at two depths (0~2 cm, $50{\pm}1cm$) of forest, field, grass land, or paddy field, distinct strains of actinomycetes were isolated and identified to the genus level. The genus-diversity of soil actinomycetes was revealed to be considerably different by seasonal change. It was also affected by soil depths, soil types, or actinomycete groups. At the soil depth of 0~2 cm, the seasonal distribution fluctuation (%) of streptomycete strains was higher in grass land (41%), field (39%) soil than paddy field (18%), or forest (18%), whereas that of streptomycete strains at the soil depth of $50{\pm}1cm$ was high in order of paddy field (36%), field (28%), grass land (26%), and forest (16%). On the other hand, the seasonal distribution fluctuation ratio of rare actinomycete strains at the soil depth of 0~2 cm was above 45% except for paddy field (26%). At the soil depth of $50{\pm}1cm$, the seasonal distribution of rare actinomycete strains exhibited high fluctuation (%) in order of forest (79%), paddy field (36%), field (24%), and grass land (10%).

박동진,김송미,Park, Dong-Jin,Kim, Song-Mi 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.8

본 연구는 다문화 청소년의 이중문화 수용태도와 교우관계의 관계에서 자아존중감의 매개효과를 살펴보고, 다문화 수용성의 조절된 매개효과를 살펴보고자 하였다. 이를 위해 한국청소년정책연구원에서 실시한 '다문화청소년패널조사' 8차년도 조사(2018)에 참여한 청소년 1,197명의 데이터를 활용하여 분석하였다. 분석결과, 첫째, 다문화 청소년의 이중문화 수용태도는 자아존중감에 유의한 정적인 영향을 미치는 것으로 나타났다. 둘째, 다문화 청소년의 이중문화 수용태도가 교우관계에 유의한 영향을 미치는 가운데, 이들 관계를 자아존중감이 부분매개하는 것으로 나타났다. 셋째, 다문화 청소년의 이중문화 수용태도가 자아존중감을 매개로 교우관계에 영향을 미치는 간접효과를 다문화 수용성이 조절하는 것으로 나타나 조절된 매개효과가 있는 것으로 확인되었다. 본 연구결과를 토대로 다문화 청소년의 교우관계를 긍정적으로 형성하고 유지하기 위한 지원방안을 모색하였으며, 본 연구의 함의, 한계점과 후속연구에 대한 제언을 제시하였다. The purpose of this study was to examine the mediating effect of self-esteem in the relationship between bicultural acceptance attitude and peer relationship of multicultural adolescents, and to examine the moderated mediating effect of multicultural acceptability. To this end, the data of 1,197 adolescents who participated in the 8th year survey(2018) of the 'Multicultural Adolescent Panel Study' surveyed by the National Youth Policy Institute were analyzed. As a result of the analysis, first, it was found that the bicultural acceptance attitude of multicultural adolescents had a significant positive effect on self-esteem. Second, it was found that while bicultural acceptance attitude of multicultural adolescents had a significant effect on peer relationship, self-esteem partially mediated these relationships. Third, it was found that multicultural acceptability moderating the indirect effect that affects peer relationship through self-esteem as a mediating bicultural acceptance attitude of multicultural adolescents. Based on the results of this study, a support plan was sought to positively form and maintain the peer relationship of multicultural adolescents, and the implications, limitations, and suggestions for subsequent studies of this study were presented.

박동진,김송미,Park, Dong-Jin,Kim, Song-Mi 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.7

본 연구는 대학생의 성취동기와 우울의 관계, 그리고 이들 관계에서 자아존중감의 매개효과를 살펴보고자 하였다. 이를 위해 Y시 소재 대학교에 재학 중인 대학생 267명의 자료를 수집하였으며, SPSS 22.0과 SPSS PROCESS macro 3.3을 활용하여 분석을 실시하였다. 연구결과, 첫째, 대학생의 성취동기는 매개변수인 자아존중감에 유의한 정적인 영향을 미치는 것으로 나타났다. 둘째, 대학생의 성취동기는 우울에 유의한 부적인 영향을 미치는 것으로 나타났다. 셋째, 대학생의 성취동기와 우울의 관계에서 매개변수인 자아존중감은 우울에 유의한 부적인 영향을 미치는 것으로 나타난 반면, 성취동기는 유의한 영향을 미치지 않는 것으로 나타났다. 이를 볼 때 대학생의 성취동기가 우울에 미치는 영향에서 이를 자아존중감이 완전매개하는 것을 확인할 수 있었다. 본 연구결과를 기초로 하여 본 연구의 함의 및 제한점을 논의하였고, 대학생에 대한 지원방안과 후속연구에 대해 제언하였다. The purpose of this study was to examine the effect of achievement motivations of university students on depression and the mediating effect of self-esteem in these relationships. For this, data were collected from 267 university students enrolled in universities in Y city, and analyzed using SPSS 22.0 and SPSS PROCESS macro 3.3. As a result of the study, first, it was found that the achievement motivation of university students had a significant positive effect on self-esteem, a parameter. Second, it was found that the achievement motivation of university students had a significant negative effect on depression. Third, in the relationship between achievement motivation and depression in university students, self-esteem, a parameter, was found to have a significant negative effect on depression, whereas achievement motivation did not have a significant effect on depression. In view of this, it was confirmed that self-esteem was completely mediated in the effect of achievement motivation of university students on depression. Based on the results of this study, the implications and limitations of this study were discussed, and support plans and follow-up studies for university students were suggested.

비출혈을 동반한 외상성 내경동맥 가성동맥류 1례 : Detachable Coil에 의한 색전술

박동진,이준호,김순곤,Park, Dong-Jin,Lee, Jun-Ho,Kim, Sun-Gon 대한기관식도과학회 2006 大韓氣管食道科學會誌 Vol.12 No.2

Traumatic pseudoaneurysm of the intracavernous internal carotid artery(ICA) is extremely rare, but it is life threatening condition because of massive recurrent epistaxis. Unfortunately, the prompt diagnosis and treatment of this disease are frequently delayed due to its rarity and variable latent period, so this disease is regarded as a challenge to clinicians. Optimal therapy for this diseases demands rapid suspicion for it and is essential in order to give the best functional outcome with minimizing its morbidity and mortality. The authors present a case of male patient with traumatic pseudoaneurysm of intracavernous ICA accompanying severe epistaxis. This patient was a 37-year-old male with unilateral blindness and recurrent massive epistaxis after suffering trauma to head. Computed tomography, MRI and carotid artery angiogram showed pseudoaneurysm of intracavernous ICA with sphenoid bone fracture. The patient was effectively managed with occlusion of the pseudoaneurysmal circulation by endovascular interventional embolization technique utilizing mechanically detachable tungsten coils.

박동진,이상래,Park Dong Jin,Lee Sang Rae 대한영상치의학회 1985 Imaging Science in Dentistry Vol.15 No.1

The incidence and associated dental abnormalities of taurodontism were studied radiographically (panoramic view) in 1895 patients of deciduous dentition and 2167 patients of permanent dentition who had visited to the Department of Oral Radiology, Kyung Hee University in Korea. The obtained results were as follows: 1. The prevalence of taurodontism was 3.59% in the deciduous dentition group, and 1.8% in the permanent dentition group. 2. There was no definite sex difference in the deciduous dentition, and the permanent dentition group. The type of mesotaurodontism was predominent in the deciduous dentition group, and hypotaurodontism in the permanent dentition group. 4. The vast majority of this abnormalities had occurred in the mandibular 1st deciduous molar in the deciduous dentition group, and mandibular 2nd permanent molar in the permanent dentition group. 5. Of the cases with taurodontism, the deciduous dentition group revealed 95.6% bilaterally, and 82% bilaterally in the permanent dentition group. 6. Multiple teeth occurance, not single tooth only, were involved in 98.5% of the cases in the deciduous dentition group, and 82% in the permanent dentition group.

Determinants of IT Usage : Test of the Revised TAM

박동진,Park, Tong-Jin 한국데이터정보과학회 2002 한국데이터정보과학회지 Vol.13 No.1

This study is design ed to assess Information Technology (IT) acceptance models among Theory of Planned Behavior (TPB), Technology Acceptance Model (TAM) and the revised TAM using structural equation modeling. Research results show that the revised TAM with perceived ease of use, perceived usefulness and IT usage variables is slightly outperformed TPB and TAM. From a managerial standpoint, the findings of this study reveal that in order to foster IT usage, it is important to encourage a positive perceived ease of use and usefulness.
