Objectives: In this study, by a professional who provides medical services by gauging the level of personality recognition among dental hygienists, the basic data is provided to suggest the need for personality education in dental hygienists' education. Methods: A questionnaire survey was conducted with the members attending conservative education in 2018, and the results of the analysis of the total of 348 members were as follows. Results: The average age of the participants was 31.6 years, and their average career duration was 9.4 years. The total personality score was 3.74 points. The highest score was 4.10 points for conscience, and the lowest score was 2.98 points for habit. In terms of differences between general characteristics and personality domains, the personality perception score was statistically significantly higher for hygienists who were married than for those with a higher education level and working at a higher hospital level. There was a statistically significant positive correlation between the personality domains and the highest competence domain (r=0.790) in relation to total personality. The higher the competency, the higher the total score. Conclusions: Personality is not a part of being formed in the short term. It should be recognized that it is important to recognize the importance of personality in the dental hygiene education curriculum and to provide opportunities to develop personality through systematic programs.

현대인의 필수품 중에 하나인 스마트폰을 이용한 악보 인식 어플리케이션은 이미 시중에도 출시가 되어 있다. 이러한 어플리케이션들은 몇 가지 아쉬운 점이 존재하며, 특히 인쇄된 악보의 인식률이 낮아서 이를 연주하는 부분에서 많은 오류가 발생하게 된다. 인쇄된 악보의 인식률을 저하시키는 중요한 원인 중의 하나는 찍은 사진에서 인식한 오선이 수평이 되지 못하고 기울어져 있기 때문에 발생한다. 본 논문에서는 프리뷰 이미지를 분석하여 기울기를 보정하여 인쇄된 악보를 촬영하는 방식을 제안한다. 제안된 기법은 수동으로 조작하여 촬영한 악보를 인식할 때보다 인쇄된 악보의 인식률을 높이는 데 기여한다.

This paper presents the development of language tutoring systems for nonnative speakers by leveraging advanced end-to-end automatic speech recognition (ASR) and proficiency evaluation. Given the frequent errors in non-native speech, high-performance spontaneous speech recognition must be applied. Our systems accurately evaluate pronunciation and speaking fluency and provide feedback on errors by relying on precise transcriptions. End-to-end ASR is implemented and enhanced by using diverse non-native speaker speech data for model training. For performance enhancement, we combine semisupervised and transfer learning techniques using labeled and unlabeled speech data. Automatic proficiency evaluation is performed by a model trained to maximize the statistical correlation between the fluency score manually determined by a human expert and a calculated fluency score. We developed an English tutoring system for Korean elementary students called EBS AI Peng-Talk and a Korean tutoring system for foreigners called KSI Korean AI Tutor. Both systems were deployed by South Korean government agencies.

Mastering a musical instrument for an unskilled beginning learner is not an easy task. It requires playing every note correctly and maintaining the tempo accurately. Any music comes in two forms, a music score and it rendition into an audio music. The proposed method of assisting beginning music players in both aspects employs two popular pattern recognition methods for audio-visual analysis; they are support vector machine (SVM) for music score recognition and hidden Markov model (HMM) for audio music performance tracking. With proper synchronization of the two results, the proposed music learning assistant system can give useful feedback to self-training beginners.

This study was conducted to investigate the subjective degree of fatigue, the degree of fatigue depending on analysis of MMPI and SDNN in middle-aged women. Data were collected from 51 patients, registered at Oriental Medicine Hospital in J-city and K-city respectively. The instrument used in this study were the Multidimensional Assessment of Fatigue developed by Belza(1995) and revised by Jung & Kim(1999) and the Minnesota Multiphasic Personality Inventory(MMPI) and Standard Deviation of Normal to Normal(SDNN). The collected data were analyzed by SPSS/WIN 9.0 program using frequencies, percentage, mean, standard deviation, t-test. The degree of fatigue in middle-aged women: the average score 30.61 out of the total score 40. Subdivision of fatigue scores: common fatigue degree 7.71, distress due to fatigue 7.67, degree of daily activity fatigue 7.43, and fatigue frequency in the previous week 7.84. The degree of fatigue according to subjective recognition was shown significant difference(t=6.707, p=.000).: group of recognition (33.58), group of ignorance (23.47). The degree of fatigue according to MMPI was shown significant difference. : In the group of recognition, scales of Hs, D, Hy, Pt were higher. The degree of fatigue according to SDNN was shown significant difference (T=-4.062, P=.000). : group of recognition (33.47ms), group of ignorance (45.70ms). The total fatigue score and scales of Hs, D, Hy in MMPI was correlated positively (r=.576; r=.466; r=.518), and total fatigue score and SDNN was correlated negatively (r=-.576). Conclusively fatigue is one of difficult problems in middle-aged women. Therefore it is necessary to develope some nursing intervention for reducing fatigue in its early stages.

This study used questionnaires to investigate the safety awareness for imported foods by 365 male and female adults in Taejon. The results of the study were as follow : By factor analysis, the subjects' behaviors and awareness of the imported food was grouped into 3 factors such as 'health and quality factor', 'purchasing factor' and 'contamination factor'. 'Health and quality factor' and 'purchasing factor' were not recognized negatively by the subjects, moreover' contamination factor' was recognized very highly. The subjects' concern and worry about the imported food was also very high. The marital status, education level, nutriton knowledge adn recognition level of contamination by pesticides and heavy metals of foods partially affected the recognitio level of imported foods. The major selection criteria of imported food were distribution period(36.3%), price(28.8%) and purchasing experience(17.3%). The imported food mean discrimination score was 8.4±3.1 out of 13. The worst discriminatio score was red pepper. The subjects' experiences with imported foods selection affected the most instead of education level or nutrition knowledge. The higher discrimination score group more negatively recognized imported food and contamination recognition level was higher whereas the lowerdiscrimination score group more positively recognized the purchasing frequency and with to buy more easily. But both groups desired to reinforce contamination control. The better discrimination score of imported food pooring recognized sanitation concerns(p<0.05), quality(p<0.05), cooking convenience(p<0.01), desire for more variety(p<0.05), and the higher contamination recognition level(p<0.05) and desire to reinforce contamination control(p<0.01).

울릉도의 피부 진균증 환자들은 타 지역에 비해 중복 감염율이 높은데, 이는 피부 진균증에 대한 환자들의 인식도가 낮기 때문으로 생각된다. 또한 가족 내 감염율도 타지역 보다 높아서 피부 진균증에 대한 예방 교육이 절실하다. 그러나, 피부 진균증 환자들의 나이가 고령화, 여성화 되고 있어 피부 진균증에 대한 인식을 높이기 위한 보건 교육을 고령 환자들과 여성 환자들에 맞추어 시행할 필요가 있다. 주위 동료들의 감염율도 높으므로 적절한 예방 교육이 이루어 진다면 피부 진균증의 예방 효과는 클 것으로 예상된다. 부족하나마 설문 조사로 피부 진균증 환자들의 피부 진균증에 대한 인식도가 미흡다는 사실은 울릉군 지역의 피부 진균증 예방교육의 필요성을 제시 할 것으로 생각된다. 추후에도 울릉군 지역의 피부 진균증에 대한 여러 가지 방면에서의 연구가 필요할 것으로 생각되며, 인식도 조사도 많은 환자와 주민을 대상으로 시행하여 통계적인 유의성을 찾아야 할 것으로 생각된다.
