조준희,최병재,심현섭,손흥규 대한소아치과학회 2000 大韓小兒齒科學會誌 Vol.27 No.4

비인강폐쇄는 연구개, 인두측벽 그리고 인두후벽간의 움직임이 서로 조화되어 구강과 비강을 나누어주는 괄약근 기전으로서 연하, 호흡 및 발음 등의 생리적 기능에 중요한 역할을 한다. 이 기능에 문제가 생긴 경우를 비인강폐쇄부전이라하며 그 원인으로는 (1) 연구개의 길이 및 움직임이상, (2) 비인두강의 해부학적 공간문제, (3) 인두 후벽과 측벽의 기능이상 등이 있다. 본 연구는 구개월 환자의 측면두부방사선 사진을 통해 비인두강을 해부학적으로 분석하고 동시에 산출된 각 모음의 과비음 정도를 평가하여 비인강폐쇄부전과의 연관성을 비교해 본 것이며, 얻어진 결과는 다음과 같다. 1.연구개 길이는 정상인에 비해 현저히 짧았다. 2.adequate ratio는 정상인에 비해 작게 나타났다. 3.adequate ratio가 감소함에 따라 모음 조음시 anatomic mVPI가 점차 증가하였다. 4.각 모음 조음시 anatomic VPI는 과비음정도와 비례관계를 보였다. 5.고모음(/u/,/i/)의 과비음정도가 저모음(/a/)에 비하여 크게 나타났다. 결론적으로, 구개열환자에서 측면두부방사선 사진은 비인강폐쇄부전의 진단 및 평가에 유용하게 사용될 수 있으며, 비인두강의 해부학적 구조는 산출되는 과비음정도와 밀접한 연관성이 있었다. Nasopharyngeal closure is a sphincter mechanism between the activities of the soft palate, lateral pharyngeal wall and the posterior pharyngeal wall, which divides the oral cavity and the nasal cavity. It participates in physiological activities such as swallowing, breathing and pronunciation. In case of an error in this mechanism, it is called a nasopharyngeal incompetence. The causes of this error are defects in (1) length, function, posture of the soft palate, (2) depth and width of the nasopharynx, (3) activity of the posterior and lateral pharyngeal wall. The purpose of this study is to analyze the nasopharynz of cleft palate patients using lateral cephalograms and at the same time, evaluate the degree of hypernasality of each vowels to find its relationship with nasopharyngeal incompetence. The following results were obtained : 1.The length of the soft palate was markedly short than normal. 2.The adequate ratio was smaller than the normal value. 3.As the adequate ratio decreased, when articulating vowels, anatomic mVPI increased. 4.When articulating each vowels, anatomic VPI was in proportion with the degree of hypernasality. 5.The degree of hypernasality was greater in high vowels(/i/, /u/) than low vowel(/a/). From the above results, it can be concluded that in cleft palate patients, lateral cephalograms can be used effectively in diagnosing and evaluating nasopharyngeal incompetence. The anatomic structure of the nasopharynx has close relation to the degree of hypernasality.

Comparison of New-Onset Diabetes Mellitus among Patients with Atrial Fibrillation or Atrial Flutter

Wei-Syun Hu,Cheng-Li Lin 대한심장학회 2020 Korean Circulation Journal Vol.50 No.6

Background and Objectives: The objective was to compare the rate of onset of diabetes mellitus (DM) in patients with atrial fibrillation (AF) as compared with atrial flutter (AFL). Methods: The incidence of DM through the national cohort registry in 14,014 newly diagnosed AF and 14,014 newly diagnosed AFL was investigated. Propensity score matching was used to optimize comparability between these 2 groups. Further analysis with Cox model, Kaplan-Meier methods and competing risk analysis were used to compare the incidence of DM in patients with AF and AFL. Results: The overall incidence of diabetes was higher among cases in AF cohort (1,653 diabetes cases, 11.7%) than in AFL cohort (1,448 diabetes cases, 10.3%). The risk of diabetes was 1.17-fold greater in the AF cohort compared with that in the AFL cohort (95% confidence interval [CI], 1.09–1.25; p<0.001). After adjustment for all relevant confounding factors in the competing risk regression model, the risk of diabetes remained significantly increased 1.16-fold in the AF cohort (95% CI, 1.09–1.25; p<0.001). Conclusions: The message of higher incidence rate of DM in patients with AF compared to those with AFL was delivered in this study.

Ming-Syun Chuang,Yin-Chien Ou,Yu-Sheng Cheng,Kuan-Yu Wu,Chang-Te Wang,Yuan-Chi Huang,Yao-Lin Kao 대한배뇨장애요실금학회 2024 International Neurourology Journal Vol.28 No.1

Purpose: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes.Methods: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery.Results: The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor.Conclusions: In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

이규보의 『동국이상국집』 영색시(詠色詩)에 나타난 색채관과 특징

이선이 ( Syun-yi Lee ) 온지학회 2019 溫知論叢 Vol.0 No.61

고려시대의 시격과 체는 당시 문인들의 시론 가운데 하나였으며, 이규보의 시는 화려하게 운을 활용하는 구조적인 특징을 가지고 있다. 제목에 있는 색명으로는 시문(詩文)에서 색명으로 사용하지 않는다. 색명인청(靑)자로 운을 사용하여, 제목과 함께 백 - 청, 흑 - 청, 황 - 청, 홍 - 청, 청 - 청의 대비효과와 방향성을 가지게 하였다. 평면에서 공간구조로 전한시킨 것이 영색시의 구조적 특징이다. 황홍청을 노래한 시의 공통점은 동식물이 자라고 뛰노는 자연에서 색을 찾으려고 하고 있다. 영홍시에는 적은 청과 대응하는 것은 뜻에 맞지 않는다고 하여 홍을 쓴 이유를 밝혔다. 기존의 사유와는 다른 면이며, 빛의 중요성을 강조한다. 이규보의 영색시는 전통 오방색 청·황·적·백·흑이 아닌 청·황·적·백·흑의 오색을 쓴다. 홍은 빛을 상징하며, 적은 청과 무늬를 이룰때 쓰인다. 때문에 홍과 적은 서로 의미가 다르고 색의 운용방식도 달라진다. 고려청자의 색은 청색 또는 비색이 아니라, 녹색으로 인식되었다. 옥석과 같은 돌의 색을 현재는 청색계열로 분류하지만, 고려는 백색계열로 인식하는 경향이 있었다. 청과 녹을 구분할 수 있었던 것은 청자가 생활 깊숙이 스며들어 있던 결과이다. 이것이 영색시를 통해서 나타난 이규보의 색채관 특징이라 할 수 있다. Forme poetique and adonien in the Goryeo Dynasty were among the Poetics, and Lee Kyu-bo's poems have structural features that utilize their luck with splendor. The color name in the title is not used as the color name in the verse. Using rhyme as the color name "靑(blue)", the contrast effect and direction of 白 (white)-靑(blue), 黑(black)-靑(blue), 黃(yellow)-靑(blue), 紅(magenta)-靑(blue), and 靑(blue)-靑(blue) were given along with the title. Translated from a plain into a spatial structure is a structural feature of Colored poetry. The common thing about poems that sing about 黃(yellow)-紅(magenta)-靑 (blue), and 靑(blue) is that animals and plants are trying to find color in nature, where they grow and run. Magenta(紅) poetry revealed why he used magenta because he said it was not right to react to red. It is different from conventional reasons and emphasizes the importance of light. Lee Kyu-bo's poetry sang the five color(blue(靑), yellow(黃), magenta(紅, or orange), white(白) and black(黑)) in five colors(blue, yellow, red, white and black). Hong(紅) symbolizes light, and is used to make blue patterns. Because of this, the magenta(紅) and the blue(靑) have different meanings and different ways of operating colors. The color of Goryeo celadon not recognized as blue or celadon green(翡色), but It was recognized as green(綠). Although the colors of stones such as jade are now classified as blue, Goryeo tended to recognize them as white. It was in the daily life of the celadon that the distinction between blue and green was made. This can be said to be the colorimetric characteristics of Lee Gyu-bo through a poem sung in colors.

Effects of Pot Size on Plant Growth of Cymbidium ‘Lovely Smile’

Myung Syun Shim,Ah Ram Cho,You Kyung Chung,Yoon Jin Kim 한국원예학회 2021 한국원예학회 학술발표요지 Vol.2021 No.10

Cymbidium is one of the most popular and economically important species cultivated as a commercial ornamental crop. The objectives of this study were to determine the appropriate pot size which gives the best plant growth characteristics. Two and three-year-old plants of Cymbidium ‘Lovely Smile’ plants were transported to an environmentally controlled Information and Communication Technology (ICT) smart greenhouse at Seoul Women’s University from a commercial greenhouse in Gongju (24 February 2021). Two and three-year old plants were repotting in plastic pots with 18 cm (2L, P2), 22 cm (3L, P3), and 25.5 cm (5L, P5) diameter filled with bark (9 April 2021). The EC of nutrient solution was maintained to 1 dS·m¹ and the pH was adjusted to 6.0 ‒ 6.5. The leaf length and width, number of pseudobulb per plant, pseudobulb diameter, number of new shoots and leaves were measured every 5 weeks after nutrient solution supply. All pseudobulbs were numbered in the order of formation in the two-year old plants (PB1, PB2, PB3, PB4) and three-year old plants (PB1, PB2, PB3, PB4, PB5, PB6, PB7, PB8, PB9). Pseudobulb diameter and leaf number of all pseudobulbs were measured. Pseudobulb diameter was in the range of 20 ‒ 35 mm and leaf number of 6 ‒ 12 in two-year old plants. Shoot number increased in P2, P5 treatments but there was no significant difference in the other plant characteristics. Pseudobulb diameter and leaf number increased in PB2, PB3, PB4 after 10 weeks of nutrient supply compared to pseudobulb diameter and leaf number in plants of 5 weeks. Pseudobulb diameter of three-year old plants was in the range of 15 ‒ 50 mm and leaf number of 4 ‒ 12. PB8, PB9 were newly formed and leaf number increased in PB4, PB5 compared to leaf number in plants of 5 weeks. There was no significant difference in plant characteristics according to pot size. Plant growth and pseudobulb changes according to pot size will be continuously investigated during the experiment to suggest standards of Cymbidium to improve plant growth and flower spike production.

Growth of Ardisia pusilla as Affected by Starch or Polyacrylate Polymer Mixed in the Media

Myung Syun Shim,Seong Youl Choi 한국원예학회 2010 Horticulture, Environment, and Biotechnology Vol.51 No.4

The objective of this study was to investigate the properties of starch and polyacrylate polymers, alone or when mixed in the media. Their effects on growth of potted Ardisia pusilla plants were also determined. The starch polymer absorbed more water than polyacrylate polymer. However, the water absorbance of starch polymer was restricted in the media which resulted in lower CC (container capacity) and higher AS (air space) than polyacrylate polymer. The CC, AP, and TP (total porosity) increased than control in the media when those were mixed with two polymers of 0.6 and 0.9%. Numbers of small pore spaces were observed in the polyacrylate polymers and the volume of the media increased more than starch, thanks to the small pore spaces which put pressure on one another during hydration. The starch had larger pore spaces which were spread out aside in the media after water absorbance. The mineral nutrient contents in the media with polyacrylate polymer were similar or higher compared to control. However, the starch polymer showed stronger retention to Ca and Fe resulted to lower mineral nutrient contents in the media. The plant growth was improved in polyacrylate treatments than control. The plant life was maintained for about 4-6 days longer in the polyacrylate treatments. The Ca contents in the leaves decreased in the starch treatments of 0.6 and 0.9% and polyacrylate treatments of 0.9% than control.The lower content of Ca restricted the plant growth, especially in the polymer content of 0.9%. In consequence, the polyacrylate polymers were more favorable in the media. They absorbed more water when mixed in the media and showed weaker retention to Ca and Fe. In addition, the polyacrylate polymers were recommended because of improved plant growth and prolonged plant life, but they should not be used in the content of more than 0.6%.
