Background: This study aims to improve dental hygiene education by investigating the relationship between metacognition, learning flow, and problem-solving abilities in dental hygiene majors. Methods: A survey was conducted on 2nd to 4th-year students from dental hygiene programs, with 132 responses analyzed. Data analysis involved t-tests and ANOVA to examine the differences in metacognition, learning flow, and problem-solving abilities based on the general characteristics. Multiple regression analysis was employed to investigate the factors influencing the dependent variable, which is problem-solving abilities. The collected data were analyzed using SPSS. Results: First, when comparing metacognition, learning flow, and problem-solving abilities based on the general characteristics of the study participants, statistically significant differences were observed in common factors such as major satisfaction, subjective academic performance, GPA (grade point average), and reason for major choice (p<0.05). Second, it was found that there is a significant positive correlation between metacognition, learning flow, and problem-solving abilities in dental hygiene students (r≥0.79, p<0.05). In other words, higher levels of metacognition and learning flow were associated with better problem-solving abilities. Third, factors influencing problem-solving abilities were identified, with both metacognition and learning flow having a statistically significant positive impact. It was also noted that metacognition had a greater influence on problem-solving abilities compared to learning flow (adjusted R2=0.815, p<0.05). Conclusion: To enhance the core competency of problem-solving abilities, it is essential to improve metacognition and learning flow. To enhance metacognition and promote learning flow, strategies such as goal setting, utilizing effective learning methods, boosting self-efficacy, managing the learning environment, choosing activities that foster immersion, stress management, self-assessment and feedback integration, improving focus, and utilization a variety of learning experiences will be necessary.

( Soo-auk Park ),( Young-sik Cho ) 한국치위생과학회 2021 치위생과학회지 Vol.21 No.1

Background: Career success is the psychological achievement associated with an individual’s work. Protean career management behavior is the behavior of managing individual careers in order to achieve individual career goals. The purpose of this study was to clarify the career success of dental hygienists as perceived by clinical dental hygienists and to compare the relationship between career success and protean career management behavior. Methods: Nationwide convenience samples of clinical dental hygienists were obtained; 354 people were surveyed online, and the data of 350 people were finally analyzed. The perception of career success of dental hygienists was assessed using a multiple response method. T-test, ANOVA, and χ² tests were performed to investigate the differences and relationships between protean career management behavior and career success according to the general characteristics. Results: Career success was recognized by clinical dental hygienists as “income”, “work proficiency”, “patient consultation”, “self-satisfaction”, and “recognition by superiors” in order. There were significant differences in protean career management behavior according to general characteristics (p<0.05). Higher career management behavior was common in those higher in age, in married participants, in those with higher educational background, and in those with a higher career, better position, and more job change experience (p<0.05). Among the variables of career success perceived by clinical dental hygienists, “work proficiency” had a significant effect on “career management behavior” (p<0.05). “Work proficiency” and “recognition by superiors” were significant in “protean technological development behavior,” and they also influenced actual behavior (p<0.05). Conclusion: The relationship between dental hygienists’ career success and protean career management behavior was clarified. Dental hygienists performed career management behaviors to develop work ability and skills. In addition, the relationship between career management behavior and long-term employment was confirmed.

Objectives: Subjective well-being is a representative indicator of quality of life. Work and life are not separated, and work itself is a part of life. The purpose of this study was to confirm the effect of psychological resources such as self-esteem, self-efficacy, GRIT, and resilience on the subjective career success and subjective well-being in dental hygienists. Methods: From November 12, 2020 to December 30, 2020, an online survey was conducted on 650 dental hygienists, and data from 630 were analyzed. For the analysis, independent two-sample t-test and one-way ANOVA were performed, and the confirmatory factor analysis and measurement model, construct validity, construct reliability, convergent validity, and discriminant validity were confirmed. This was verified using a structural equation model. SPSS 18.0 and AMOS 18.0 were used for the statistical analyses; p<0.05 were considered statistically significant. Results: The final model fit was found to be suitable. There was no significant difference in subjective career success with respect to the personal characteristics and career characteristics, except for total career and number of turnovers. There was no significant difference in subjective well-being according to personal characteristics and career characteristics. Psychological resources such as self-esteem, self-efficacy, GRIT, and resilience were significant for subjective career success (p<0.05, R²=0.637). Subjective career success was significant for subjective well-being (p<0.05, R²=0.378). Among the psychological resources, self-esteem had both direct and indirect effects on subjective well-being (p<0.05). Conclusions: Positive psychological resources, rather than external conditions, are an important prerequisite for subjective career success and subjective well-being. Thus, it is proven that work is a part of life.

Objective: The purpose of this study was to analyze the clinical characteristics and prognosis of small cell uterine cervical carcinoma with neuroendocrine differentiation. Methods: Patient's medical records were reviewed retrospectively who were diagnosed as small cell carcinoma of uterine cervix and were treated at Hanyang University Hospital between 1972 and 1997. Results: Between 1972 and 1997, of 1164 patients who were diagnosed as invasive cervical cancer, there were 10 cases of small cell carcinoma of uterine cervix in the department of obstetrics and gynecology, Hanyang University Hospital. The incidence of small cell carcinoma in invasive cervical cancer was 0.9% (10/1164). Of 10 small cell carcinoma, seven(70%) were neuroendocrine types which were identified with several kinds of immunohistochemical stains (Chromogranin, Grimelius, and/or NSE). The age of these 7 patients ranged from 34 to 63 years (mean 49). Two were in stage Ib, 3 in stage IIa, I in stage IIIb, and 1 in stage IVb. Patients with stage Ib-IIb (n=5) received 3-5 courses of neoadjuvant VBP chemotherapy (vinblastine, bleomycin and cis-platinum) followed by radical hysterectomy with pelvic and paraaortic node dissection. One IIIb patient was managed with concurrent chemo-radiation(3 cycles of cis-platinum & 5-FU) followed by 6 courses of chemotherapy. One IVb patient was treated by palliative chemotherapy with 8 cycles of VBP chemotherapy. Of 5 patients who underwent surgery, none showed pelvic lymph node metastases. These 7 patients were folk$gt;wed for 8 - 62 months (average: 20 months). During this period, 5 patients died of disease between 8 and 62 months later and 2 patients are still alive for 12 (stage Ib) and 26 months (stage Ib), respectively. In the contrary, of 3 patients without neuroendocrine differentiation, who underwent neoadjuvant VBP chemotherapy followed by radical hysterctomy with pelvic and paraaortic node dissetion or concurrent chemo-radiation, two stage IIb patients are still alive for 58 and 74 months, and one IIIb patient died of disease 12 months later. Conclusion: In summary, neuroendocrine differentiation seemed to adversely affect the prognosis and longterm survival of small cell carcinoma of uterine cervix. So, for this high risk group, more aggressive therapy would be need to improve outcome. However, as the number of patients were small in our study, further study with large number of patients are warranted.

Objectives: Recently, subjective career success has been used as a criterion for evaluating career success. The purpose of this study was to develop and evaluate a simplified subjective career success inventory for dental hygienists. Methods: Subfactors of the subjective career success inventory consisted of career satisfaction, employability, and job satisfaction. The validity and reliability of the existing tools were evaluated through the basic items composition, content validity index (CVI), preliminary survey, and main survey process according to dental hygienists. The preliminary survey was composed of 35 questions by verifying the content validity twice from the existing 63 questions, and the main survey was conducted with a total of 12 questions. Samples were conveniently extracted from dental hygienists with a clinical career of ≥3 years and surveyed online from March 12, 2020 to June 30, 2020. Data of 320 people were collected, of which 284 were finally analyzed. The validity and reliability were analyzed using SPSS 18.0 and AMOS 18.0 (p<0.05). Results: The subjective career success was a shortened inventory composed of nine questions, and the overall reliability was Cronbach's α=0.841. Using exploratory factor analysis, three factors were extracted. As a result of the confirmatory factor analysis, each measurement variable significantly explained the latent factor, and the fit of the model was appropriate. The fit of the model was appropriate for the structural equation model. Among the sub-factors of subjective career success, career satisfaction and job satisfaction had a significant effect on intention to stay (p<0.05). Conclusions: The simplified subjective career success inventory developed for dental hygienists was found was found to be a useful tool in terms of reliability and validity.

현재 스마트 스피커는 사용자의 명령어에 반응하는 수동적인 서비스 제공에서 더 나아가, 먼저 말을 걸어 서비스를 제공하는 능동적인 선제적 서비스로 그 범위가 확장되고 있다. 선제적 서비스 제공 시에 스마트 스피커가 적절하지 않은 순간에 말을 걸면 사용자의 과업을 방해하고 부정적인 감정(짜증 등)을 초래하는 문제가 발생한다. 따라서, 말을 거는 타이밍이 선제적 서비스 제공에 있어서 매우 중요한 요소이다. 본 연구에서는 말을 걸기 적절한 순간을 탐험적으로 찾기 위해 스마트 스피커를 제작하여 일주일간 대학생 기숙사 방에 설치하여 데이터를 수집하였다. 스피커가 “지금 대화하기 좋은가요?” 라는 질문을 하면 실험자는 “네/아니요”로 중단가능성(interruptibility)에 대해 응답하고, 그 때 하고 있던 행동을 서술하는 방식으로 데이터를 수집하였다. 40 명의 실험자의 자연스러운 생활 중에 총 3572 개의 데이터를 수집하였다. 집에서 가능한 행동을 분류하고, 행동과 관련하여 중단가능성에 영향을 주는 주요 요인들로 집중도/몰입도, 급함/바쁨, 신체/정신적 요인, 음성 채널 유효성이라는 네 가지 요인을 찾았다. 본 연구에서 찾은 요인들을 기반으로, 스마트 스피커가 대화하기 좋은 순간에 선제적 서비스를 제공할 수 있는 기능을 스마트 스피커에 추가할 수 있을 것이다.
