This is a serious situation of livestock farmers in recent avian influenza occurrence. Influenza can lead to complications such as bacterial pneumonia, otitis media, acute respiratory diseases, and chronic diseases such as heart failure worsened, asthma, diabetes, etc. increases the threat of serious complications occur. So find out the status of influenza in 2009 NYSDOH for predicting influenza infection data up to 2014, using data mining techniques to analyze and study it. To determine the density distribution of the data based on the verification of the results were required for comparing the Visualize the algorithm for each situation. Applying a principal component analysis (PCA) algorithm to improve performance, and the performance is evaluated by verifying the accuracy of the classification model.In this paper, we apply the Influenza Laboratory Confirmed Cases Reported to NYSDOH experimental data, especially in the cluster classification algorithm using MakeDensityBasedCluster predicted influenza infection.

본 연구의 목적은 초등학교 6학년 학생들의 그래프 해석이 어떠한지를 살펴보고, 이를 토대로 그래프 해석 능력을 향상시킬 수 있는 지도 방안을 모색하는 데 있다. 연구문제 해결을 위하여 그래프 해석 검사 결과를 분석하고 그래프 해석 지도 방안을 마련하여 적용하였다. 이를 통해 학생들은 그래프를 해석할 때 양적인면과 질적인 면을 종합적으로 볼 수 있게 되었으며, 그래프와 실생활을 관련지어 생각하면서 그래프의 실용성을 체득하게 되었다. 이를 토대로 학생들의 그래프 해석능력을 향상 시킬 수 있도록 지도 방안을 개선하는데 도움이 될 수 있을 것이다. The purpose of the study is to examine how the 6th graders interpret graphs, and on basis of the research, to seek for guidance on ways to improve their analysis capabilities. All the students from two classes of D elementary school in Busan became the target to examine how to interpret graphs. On the basis of the result, 6 students who characterized by graph interpretation got an in-depth interview and the outcome was analyzed in detail. The students are able to understand both quantitative and qualitative meaning of graphs and they learned practicality while they think of graphs connecting with real life, most of all they have been interested in interpreting the meaning of graphs.

Purpose : This study aimed to investigate the effects of academic stress, ego-resilience, and grit on the perceptions of the nursing profession among nursing students who have undergone clinical training following the COVID-19 pandemic outbreak. Method : Employing a descriptive research design, data were collected from 177 nursing students across three universities in City C, Gyengsangnam-do between October 11 and October 17, 2022. The gathered data were analyzed using IBM SPSS/WIN 21.0. Results : The factors significantly influencing participants’ perceptions of the nursing profession included ego-resilience (β=.404), being a junior student (β=.206), and the intention to work as a nursing practitioner in a hospital setting upon graduation (β =.192), The combined explanatory power of these variables was 37.2% (F=9.01, p<.001, R2=.418, Adj. R2 =.372). Conclusion : The findings underscore the importance of fostering ego-resilience and enhancing understanding of the nursing profession through a systematic curriculum in the post-COVID-19 era. Establishing an accurate perception of the nursing profession will aid nursing students in improving their professional competency and commitment.

Purpose: periodontal health index is a dentist-centered index in which dentists perform examination and evaluation. Therefore, it is not appropriate for evaluation subjective symptoms and satisfaction levels of patients. To compensate for this shortcoming, we made use of a subjective index of periodontal health status with which patients can evaluate their oral health status. This research evaluated the usefulness of Periodontal age index in examining subjective consciousness of periodontal health status, estimated the number of existing permanent teeth, which is the objective index for oral health, and compared the relationships between them. Materials and Methods: The number of subjects was 2,198, consisting of 1,115 (50.7%) men and 1.083 (49.7%) women. The periodontal age increased in the 18-24 and 40-44 age groups. There were no significant differences between the 40-44 and 55-59 age groups. Further, periodontal age decreased in those aged over 60-64. Results: In this study, periodontal age index increased to age 40 when teeth are lost to periodontal disease and decreased with a decline in the number of permanent teeth. Conclusion: Therefore, the periodontal age index reflects the periodontal state rather than hypofunction by tooth loss.

철근콘크리트의 압축강도를 추정하기 위해 국부파괴법이 이용되나 구조물에 미치는 영향과 비용 소모를 최소화하기 위해 반발경도법, 초음파전달속도법과 같은 비파괴시험법을 활용하여 구조물을 평가한다. 압축강도 추정 제안식은 국내·외에서 많이 발표되었지만 실험 환경이나 양생 조건에 따라 다른 값을 나타내기 때문에 정확한 압축강도 추정이 어려운 실정이다. 본 연구에서는 국내·외에서 제안된 여러 압축강도 추정식을 사전에 제작된 표준시편에 적용해 비교 분석하였으며, 그 결과 해당 표준시편(보통강도 콘크리트)에서는 일본건축학회의 압축강도 추정식이 가장 신뢰도가 높은 것으로 나타났다.

Three patients (2 maxillary anterior teeth and 1 maxillary second premolar) underwent clinical crown lengthening procedures with forced eruption. All teeth had undergone complete root canal treatment prior to the procedure. Using an elastic band, extrusion of teeth was planned; during a 2-month period of extrusion, activation and fiberotomy were performed within a 2-week period. Following an 8-week period of maintenance, gingivectomy without bone surgery was performed. The patients were then referred to the department of prosthodontics for the fi nal prosthodontic restoration. After completion of the fi nal prosthodontic restoration, esthetically satisfactory results were reported in all three cases. These cases demonstrate the safety and simplicity of the clinical crown lengthening procedure through orthodontic extrusion for treatment of subgingivally fractured teeth; hence, it is more acceptable to the patient.
