Objectives: The purpose of this study was to examine the job awareness of dental hygiene students about a dental hygienist, what duties they wanted to do as dental hygienists, their awareness of college courses related to the job performance of dental hygienists and whether they viewed the courses as what`s most widely utilized for theclinical job performance of dental hygienists. It`s ultimately meant to help provide goodeducation for dental hygiene students to have the right understanding of dental hygienists and bolster their professionalism. Methods: The subjects in this study were 301 dental hygiene students in four different colleges located in the metropolitan area. A survey was conducted to find outtheir satisfaction level with the department of dental hygiene, personal characteristics, awareness of college courses and awareness of the duties of dental hygienists. Results: The group of students who deemed the life span of the dental hygienist occupation to be long put more significance on the college courses that should focus on job performance. As for the relationship between their personal characteristics andawareness of the college courses, their satisfaction or dissatisfaction with the department and their ideas on thelife span of the occupation made significant differences to that. The group of students who considered the life span of the occupation to be longer thought that the college courses would be more linked to theduties of dental hygienists and their job performance and should be given moreweight, and there were significant differences among them in their view of the life span of the occupation and awareness of the college courses that should be givenmore weight(p<.05). Their view of how much the college courses would be linked to the duties of dental hygienists had a statistically significant correlation to that of the college courses that should focus on the clinical job performance of dental hygienists. Conclusions: The above-mentioned findings suggest that as part of the regular curriculum, the kind of education that aims at boosting the professionalism and job performance of dental hygienists as experts should be provided for dental hygiene students to build the right values as professional dental hygienists.

전 세계적으로 화석연료의 많이 사용이 증가되고 있으며 이로 인해 온실가스가 배출되어 지구 온난화와 환경오염이 심각해지고 있는 실정이다. 지구의 환경오염을 줄이기 위해서 무공해 청정에너지인 신재생에너지에 대한 관심이 증가되는 추세인데, 그중에서도 풍력발전은 환경오염 물질을 배출하지 않고, 자원량이 무한대이기 때문에 많은 관심을 받고 있다. 하지만, 풍력발전은 전력 생산량이 불규칙한 단점을 갖고 있어 풍력 터빈의 손상과 전력 생산량이 불규칙적인 문제를 야기하여 이러한 문제점을 보완하기 위해 풍력 발전량을 정확하게 예측하는 것이 중요하다. 풍력 발전량을 정확하게 예측하기 위해서 전력 생산량이 급증 또는 급감하는 것을 의미하는 ramp의 특성을 잘 활용해야 한다. 이 논문에서는 예측의 정확도를 높이기 위하여 다계층 신경망을 이용해 예측모델을 구축하였다. 구축된 예측모델은 흔히 사용되는 풍속, 풍향 속성뿐만 아니라 Power Ramp Rate(PRR) 속성까지 사용하였다. 구축된 풍력 발전량 예측모델은 앞서 말한 세 가지 속성을 모두 사용한 경우, 두 속성을 조합하여 사용한 경우 총 4가지 예측모델을 구축하였다. 구축된 4가지 예측모델을 성능평가 한 결과 PRR, 풍속, 풍향의 속성 모두를 사용한 예측모델의 예측 값이 풍력 터빈에서 관측된 관측 값에 가장 근접하였다. 그로 인해 PRR 속성을 사용하면 풍력 발전량의 예측 정확도를 향상 시킬 수 있었다. Fossil fuel is used all over the world and it produces greenhouse gases due to fossil fuel use. Therefore, it cause global warming and is serious environmental pollution. In order to decrease the environmental pollution, we should use renewable energy which is clean energy. Among several renewable energy, wind energy is the most promising one. Wind power generation is does not produce environmental pollution and could not be exhausted. However, due to wind power generation has irregular power output, it is important to predict generated electrical energy accurately for smoothing wind energy supply. There, we consider use ramp characteristic to forecast accurate wind power output. The ramp increase and decrease rapidly wind power generation during in a short time. Therefore, it can cause problem of unbalanced power supply and demand and get damaged wind turbine. In this paper, we make prediction models using power ramp rate as well as wind speed and wind direction to increase prediction accuracy. Prediction model construction algorithm used multilayer neural network. We built four prediction models with PRR, wind speed, and wind direction and then evaluated performance of prediction models. The predicted values, which is prediction model with all of attribute, is nearly to the observed values. Therefore, if we use PRR attribute, we can increase prediction accuracy of wind power generation.

Objectives: The purpose of this study was to grasp association with dental hygienists` job expectation through correlation between curricular subjects for the department of dental hygiene and job. Methods: It carried out convenience sampling of dental hospitals where are located in Capital Area, and then conducted a self-administered questionnaire survey targeting 274 dental hygienists who are working here. The statistical program was analyzed by using PSAW 18.0. Results: Research subjects` 60.2% experienced turnover. Its reason accounted for 31.7% with the working condition. As a result of examining difference in experience of turnover according to dental hygienists` individual characteristic and working form, the significant difference was shown in age, marriage, annual salary, working institution, and career. In consequence of confirming association between curricular subjects and job, the majority showed high correlation. However, the correlation with oral physiology, clinical dental hygiene, and dental clinics showed low correlation as the insignificant variable. Conclusions: As a result of this study, the high correlation between curricular subjects and job can be considered to reflect dental hygienists` job expectation. On the other hand, the working condition, professional sense, and turnover experience, which are factors related to dental hygienists` job expectation, were indicated to fail to meet job expectation.

Objectives: This study provided students of University with CPR (cardiopulmonary Resuscitation) training and investigated their knowledge on the training, attitude, level difference, and re-training necessity related factors to find the results as follows; Methods: Frequency and t-test was performed using SPSS 21.0, and were conducted according to the need for re-education in order to determine the determinants of the students. Results: The knowledge on CPR was 10.88 on average; training necessity, 3.43; emergency response ability, 3.39; and CPR performance level, 3.10. Factors determining re-training to maintain educational effect were found to increase with increase in school year (p<0.001), training necessity escalation (p<0.001), and decrease in confidence of performing CPR (p<0.01). Conclusions: Based on the findings above, it was found that, although CPR training is generally conducted in dental hygiene education, its training effect decreased with time in terms of implementation performance, compared with students` knowledge. Moreover, students who had completed the training strongly suggested the need for re-training. In this sense, schools will need to reinforce re-training as much as new training programs and the cycle needs to be as short as within 6 months for practical training system.

본 연구는 임상현장에 의뢰된 아동을 발달장애, 행동장애, 정서장애 집단으로 분류하고, 대응분석을 통해 놀이표현형태의 인지 요소의 속성과 내용을 파악하여, 아동기 장애집단별 놀이표현형태의 임상적 프로파일 자료를 제시함으로써 보다 효과적인 치료자의 반응 방법과 치료목표를 설정하는데 그 목적이 있다. 본 연구의 결과 인지 요소의 장애 집단별 임상적 프로파일의 속성 중 인지수준은 발달장애와 정서·행동장애 간에 뚜렷한 차이를 보여주었으며, 인지적 표현방식은 정서장애와 행동장애 아동 간에 차이를 보여주었다. 인지수준에서 발달장애 아동은 매우 부족한 것으로 나타났으며, 반면 정서장애와 행동장애 아동은 인지적 수준이 적절하여 서로 유사한 속성을 보여주었다. 인지적 표현방식에서는 정서장애아동은 놀이에 대한 언어적 표현과 놀이의 논리적 전개 수준이 우수하게 나타났으며, 반면 행동장애 아동은 놀이전개의 창의성 수준이 우수한 속성을 가지는 것으로 나타났다. 아동기 장애 집단에 따라 인지요소에 대한 임상적 프로파일 내용(사용수준, 내용수준, 확장수준, 논리수준, 창의수준, 언어이해, 언어표현)은 차이가 나타났다. 발달장애 아동은 사용수준, 내용수준, 확장수준, 논리수준 및 전반적인 영역에서 모두 매우 적절하지 못하다고 나타났고, 행동장애 아동은 확장 수준, 창의 수준이 매우 적절한 반면 논리적 수준이 적절하지 못한 것으로 나타났다. 그리고 정서장애 아동은 사용수준, 논리 수준, 언어적 이해와 언어적 표현 수준이 매우 적절했고, 확장수준이나 창의 수준은 적절하지 못한 것으로 나타났다. 본 연구는 놀이라는 매체가 장애 집단별 아동의 인지 발달 수준을 평가하는데 필요한 많은 정보를 제공하고 있다는 사실을 실제 임상현장에 의뢰된 사례분석을 통해 제시하였으며, 이러한 놀이정보를 통해 아동의 장애 집단별 특성에 맞는 효과적인 반응법과 치료목표를 설정하는데 필요한 임상적 프로파일 자료를 제시하였다는데 의의가 있다. The purpose of this study is to investigate clinical characteristics and attribution of children treated with play therapy for developmental, behavioral, and emotional disorders. Subjects of this study were 118 three- to nine-year-old children randomly selected from children who were receiving or already completed play therapy at one of the child and family counseling centers in Cheong-Ju City. The results showed that the cognitive level was lower in children with developmental disorder than children with emotional or behavioral disorder. The cognitive level of children with emotional or behavioral disorder was proper. Children with emotional disorder were superior in terms of linguistic expression and logical development, and children with behavioral disorder were superior in the creativity level of play expression. Children with developmental disorder showed very inappropriate levels of clinical profiles: use, extension, logic, and general areas. Children with behavioral disorder showed proper levels of extension, contents, and creativity although their level of logic was inappropriate. In addition, children with emotional disorder showed very appropriate levels of use, logic, and linguistic comprehension and expression, but their levels of extension and creativity were inappropriate.
