Purpose : This study was designed to evaluate the efficacy and utility of panoramic radiograph for the improvement of the periodic oral examinations. Materials and Methods : Clinical examinations and panoramic examinations were done for the 242 subjects of oral examinations. The results of panoramic radiograph interpretation were compared with the clinical findings. Two questionnaires were created. One was carried out before the panoramic examination and the other done afterwards, to find out the subjects' cognition and satisfaction for the clinical and panoramic examinations. Results : 1. Panoramic findings showed a higher detection rate of 31.9% for periodontal diseases, and 23.1% for dental caries than clinical findings. 2. The additional abnormalities detected through panoramic examinations were impacted tooth in 81 subjects (33.6%), maxillary sinus abnormalities in 28 subjects (11.6%), condylar abnormalities in 5 subjects (2.1%), congenital and acquired dental anormalies in 59 subjects (24.5%), and other miscellaneous abnormalities in 34 subjects (14.1%). 3. 164 subjects (67.8%) were satisfied with the current periodic oral examination, and 75 subjects (31.1%) hoped for better accuracy. 4. In the first and second questionnaire, 154 subjects (67.0%) and 163 subjects (70.6%) responded respectively that panoramic examination was necessary, and 193 subjects (83.2%) responded that it actually helped. Conclusion : The panoramic examination was revealed to improve the effectiveness of the periodic oral examination and to increase the satisfaction of the subjects of examination.

그리프스(Charles Tomlinson Griffes)의 피아노 음악: Sonata(1919) 연구를 중심으로

신민정 ( Min Jeong Shin ) 한국피아노학회 2015 피아노음악연구 Vol.9 No.-

The progression and development of Classical music from the late 19th to the 20th century was a turning point and landmark period in music history. Formally and harmonically, many disparate works were composed, and composers broke traditional molds, experimenting and constructing their own revolutionary paths. Charles Tomlinson Griffes’(1884-1920) entire output reflects this trend, as his productive years coincided exactly with this time frame. In spite of his relatively short lifetime, Griffes’ compositional legacy showed his gradual compositional evolution. Also, the genres Griffes covered are quite broad, but among these diverse genres, his attachment to the piano was very special, as it was the first instrument of his musical studies. As a skillful and polished pianist, Griffes expressed his musical imagination primarily through the genre of piano solo, and the list of his entirepiano solo repertoire shows how Griffes’ compositional concept changed and developed during the first two decades of the 20th century. The purpose of this study is to catalogue Griffes’ solo piano works by three main periodic categories and to examine their notable characteristics along with Griffes’ gradual evolutionary compositional progression from a performer’s view. Among his piano works, Sonata composed in Griffes’ late years is the most famous one, being evaluated as firmly woven architectural piece with various new accidental, abstract, and metallic sounds by opening new prospect in 20th Century atonal music. In Sonata, Griffes devised his own so called ‘artificial scale’ which was a new logic to weave countless nonharmonic notes. Compared to such well known American composers as Aaron Copland, Charles Ives, Samuel Barber, or Elliot Carter, it is very true that Griffes’ piano works are rarely programmed or performed nowadays. However, it seems necessary to provide more opportunities for audiences to appreciate not only Griffes’ own unique impressionistic colors which differ greatly from Claude Debussy and Maurice Ravel, but also revolutionary sound especially reflected in his late Sonata. Overall, this paper shed new light on the value and importance of his music, hidden treasures and gems in the vast realm of the piano repertoire.

사회성은 인간 삶의 고유 영역이자 종합적인 능력으로서 중요한 가치를 지닌다. 일반 통념상 사회성 부족이 게임 이용의 대표적인 문제점으로 지적되는 가운데, 본 문헌 고찰에서는 비디오 게임 중 온라인 비디오 게임을 대상으로 사회적 역량과의 관계를 살펴본 연구들을 분석했다. 해당 분야에는 현재 온라인 게임안의 관계가 실제 관계를 대체하거나 보완하여 사회성 발달을 저해할 것이라는 견해와 온라인 비디오 게임이 직접적으로 사회성에 악영향을 미치지 않으며 오히려 사회적 학습의 공간을 제공함으로써 유익한 결과를 낼 수 있다는 주장이 팽팽하게 맞서고 있다. 또한 온라인 게임 이용과 심리특성 및 사회적 역량을 측정한 대규모 설문 조사에서도 게임 이용과 사회성 저하 간의 뚜렷한 관계성이 관찰되지 않았다. 이에 본 문헌 고찰 연구를 통해 온라인 게임 플레이가 사회성 저하를 초래한다는 고정관념에서 벗어날 것과 관련 연구의 타당성을 높이기 위한 노력이 필요함을 제안한다. Sociability is an inherent part of human life and also possesses an important value as a comprehensive ability. While the lack of sociability has been pointed out as a representative problem of game use in general, this paper analyzed studies on the relationship between online video games and social competence. In this field, the view that the relationship in the online game may replace or complement the actual relationship and will potentially hinder the development of sociability currently faces a conflict with the opinion that online video games may not directly have a negative effect on sociability but rather result in a positive outcome by providing a social learning space. In a large scale survey that measured the use of online games, psychological characteristics, and social competence, no distinct relationship between game use and degradation of sociability was observed. Based on this analysis, we suggest that efforts are necessary to break away from the stereotype that online game play may cause a decline in sociability and to improve the validity of related research.

Purpose This study seeks to understand the changes in the structure of the Korean export industry and the composition of export items since the 2000’s and analyze the effects of these changes on the international freight transportation mode choice pattern. Design/Methodology/Approach All yearly exports of Korea during the period of 2000~2019 were aggregated into 6 units of HS codes (published by WCO). The freight transportation mode choice pattern was analyzed by dividing these into four (4) manufacturing groups according to the industrial technology level of ISTANS (operated by the Korean government). Findings Due to the difference in the export industrial technology level and the change in the composition ratio of the export structure of Korea, the international freight transportation mode competition between air and maritime has been intensifying since the 2000’s. In particular, this phenomenon is found to be led by the mid-high and mid-low levels of industrial technology-related export industries. Research Implications The international freight transport mode choice methods vary greatly depending on the national export structure and the industrial technology level of export products. Freight transport mode competition between air and maritime is expected to accelerate in the future due to intensifying competition in the global supply chain.
