정상 교합자의 비인두와 Adenoid 성장에 관한 누년적 연구
지명주,박경덕,성재현 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.4
본 연구는 비인두와 adenoid의 성장발육 양상을 조사하여 부정교합자의 진단에 있어 비호흡 기능 평가시 유용한 기준을 얻기 위하여 시행되었다. 남자 19명, 여자 14명, 총 33명의 정상 교합자를 대상으로 8.5세부터 18.5세까지 촬영된 10년간의 누년적 측모 두부 X선 규격사진을 연구 자료로 비인두와 adenoid 부위의 거리와 면적 및 상대적 기도 비율을 계측 분석하여 다음과 같은 결론을 얻었다. 1. 각 연령(8.5세-18.5세)에서 남녀별 각 계측항목의 평균과 표준 편차를 얻었다. 2. 비인두의 height와 depth는 남자에서 14.5세까지, 여자에서 12.5세까지 성장하였다(p<0.05). 3. 비기도의 상대적 면적은 8.5세에 최소치를 나타내었고 남자는 10.5세부터 12.5세 사이에, 여자는 12.5세부터 14.5세 사이에 유의한 증가를 나타내었다(p<0.05). 4. 비기도의 상대적 면적과 비기도 관련 계측항목 간의 상관분석에서 Ad2-PNS, Ad2-PNS/Ho'-PNS 및 Upper pharynx가 남녀 모두 전 연령구간에서 비기도의 상대적 면적과 상관성이 있었다(p<0.01). The purpose of this study was to evaluate the growth pattern of nasopharyx and adenoid and to obtain useful measurements for evaluating the fuction of the nasal breathing. The biennial serial cephalometric radiographs of 33 samples(19 male, 14 female) with normal occlusion from 8.5 years to 18.5 years of age were used in this study. The distances, areas and ratios on nasopharynx and adenoid were measured and analyzed in each age and sex. The results of this study might be summarized as follows; 1. The mean value and standard deviation of each measurement was obtained in each age and sex. 2. The nasopharyngeal height and the nasopharyngeal depth increased significantly by 14.5 years of age in male and 12.5 years of age in female(p<0.05). 3. The relative nasal airway area showed the minimal value at 8.5 years of age and showed significant increase from 10.5 years to 12.5 years of age in male and from 12.5 years to 14.5 years of age in female(p<0.05). 4. In the correlation analysis between the measurements on the nasal airway and the measurement of relative nasal airway area, the measurements of Ad2-PNS, Ad2-PNS/Ho'-PNS and Upper pharynx appeared significant correlation with the measurement of relative nasal airway area(p<0.01).

AN IMPROVED ALTERNATIVE WENO SCHEMES WITH PERTURBATIONAL TERMS FOR THE HYPERBOLIC CONSERVATION LAWS
성근민,하영수,강명주 한국산업응용수학회 2023 Journal of the Korean Society for Industrial and A Vol.27 No.4
This paper aims to improve the alternative formulation of the fifth- and sixth-order accurate weighted essentially non-oscillatory (AWENO) finite difference schemes. The first is to derive the AWENO scheme with sixth-order accuracy in the smooth region of the solution. Second, a new weighted polynomial functions combining the perturbed forms with conserved variable to the AWENO is constructed; the new form of tunable functions are invented to main- tain non-oscillatory property. Detailed numerical experiments are presented to illustrate the behavior of the new perturbational AWENO schemes. The performance of the present scheme is evaluated in terms of accuracy and resolution of discontinuities using a variety of one and two-dimensional test cases. We show that the resulted perturbational AWENO schemes can achieve fifth- and sixth-order accuracy in smooth regions while reducing numerical dissipation significantly near singularities.

It is considered as the important roles of pharmacists to review prescriptions before starting dispensing. We have analyzed the details of telephone or written inquiries on the prescriptions collected from January, 1986 to December, 1986 for one year. Frequency of inquiries was about 1.1% or 410 prescriptions per month, (4925 out of 453,358 prescriptions from inpatients and outpatients). The details of the inquiries were dosage (28.6%), drug name(27.1%), strength(13.2%), insufficient writting of presciption to the rules(8.3%), administration schedule, dosage form, period of medication and so on. As to the writing errors of drug names which are most frequently occur, the causes were also analyzed. As a result of the review we can be concluded that it is desirable to educate doctors about prescription writing to decrease prescription errors.

Since 2015, the Health Insurance Review and Assessment Service (HIRA) has performed annual qualitative assessments of asthma management provided by all medical institutions that care for asthma patients in Korea. According to the third report of qualitative assessment of asthma management in 2017, the assessment appears to have contributed to improving the quality of asthma care provided by medical institutions, especially primary clinics. However, there is still a gap between the ideal goals of asthma management and actual health care policies/regulations in real clinical settings, which leads to the state of standstill with respect to the quality of asthma management despite considerable efforts such as the qualitative assessment of asthma management by national agencies such as the HIRA. At this point, a harmonized approach is needed to raise the level of asthma management among several components including medical policies, efforts of academic associations such as education and distribution of the guideline for management, and reliable financial support by the government.
