반대교합은 교두간섭이나 유구치의 조기상설 등에 의해 하악이 기능적인 전방위로 위치된 기능성 반대교합과 하악골의 과성장,상악골의 열성장 또는 양자가 복합된 골격성 반대교합,구치부의 관계는 1급이나 전치부의 치축경사가 조화를 이루지 못해 발생되는 치성 반대교합으로 분류된다. 1970년 Rölf Fränkel에 의해 소개된 Functional regulator(FR)의 한 종류인 FR-III는 상악의 열성장을 동반한 반대교협을 개선하기 위해 유치열기,혼합치열기,및 초기 영구치열기에 사용되고 있다. 이 장치는 비정상적인 근육력을 차단하여 구강내 치열 및 악궁에 대한 힘의 불균형 상태를 개선하고,구강주위의 근육을 훈련시켜 새로 형성된 힘의 균형에 의해 이차적으로 악안면골의 크기와 형태를 변화시킨다. 본 증례는 상악 중절치가 맹출하기 전에 미약한 상악 열성장과 전치부의 깊은 교합을 동반한 전치부 반대교합을 FR-III로 치료하여 양호한 결과를 얻었기에 이에 보고하는 바이다. In children with Class III malocclusion, it is important to identify whether the etiology is functional, dental, skeletal. FR-III developed by Rölf Fränkel in 1970, has been used during deciduous, mixed, and early permanent dentition to correct class III malocclusion characterized by maxillary skeletal retrusion. According Frankel, the vestibular shields and upper labial pads act to counteract the forces of the sur rounding musculature that restrict forward maxillary development and cause a retrusion in maxillary tooth position. This can achieve favorable developments with the basal bone. teeth and alveolar bone. We report FR-III that can be applicated in cases of early mixed dentition with mild maxillary deficiency and deepbite before the eruption of permanent maxillary incisor.

골격성 부조화가 없는 I급 부정교합은 치아-악궁 간의 크기 차이에 의한 총생(crowding)이나 공극(spacing)이 주된 문제점이다. 이와 같은 경미한 공간 부조화를 개선시키고자 할 때,치열의 종류,치아-악궁크기 부조화의 양,환자의 협조도,또는 환자의 요구 등에 따라 치료 방법은 다양할 수 있다. 본 증례보고에서는 I급 구치부 관계를 지니면서 전치부의 치아-악궁크기 부조화의 양이 크지 않은 영구치열에서 상하 악 전치부의 경미한 총생이나 공극이 관찰되는 경우에 사용할 수 있는 clear aligner와 spring aligner 장치의 이용에 관하여 보고하고자 한다. 이와 같은 장치들의 임상 적용에는 몇 가지 제한적인 조건이 있기는 하지만,잘 선택된 증례에서는 매우 유용하며 편리하게 이용될 수 있다. 특히 총생이 존재하는 경우에는 이를 해소시킬 공간이 치열 내에서 확보되어야 하므로,확실한 분석과 진단으로 치아 인접면 삭제의 양을 정확히 결정하여 각 치아들의 근심면과 원심면에서의 삭제의 양이 균등히 이루어질 수 있도록 하는 것이 바람직하다. 또한 치간에 공극이 존재하는 경우에는 배열 후 치열궁 둘레의 감소와 함께 상하악 전치부 간의 over-jet 문제가 생길 수 있어 대합치열과의 교합관계에 신중을 기하여야 한다. Class I malocclusion without skeletal problem results from tooth size/arch-size discrepancies, either evidenced by crowding, or spacing problems. Treatment method can be chosen according to dentition, the amount of arch discrepancy, patient compliance, or patient demands. We report of clear aligner and spring aligner that can be applicated in cases of permanent dentition with minimal arch discrepancy in anterior segment. There are some limits of application, but these are very useful appliances in the selective case. When crowding exists, definitive analysis and diagnosis should be made before starting treatment because certain amount of space must be obtained somewhere in the dentition to resolve the crowding. Therefore, appliance should be applied when lacking space is small. Also, in cases with spacing arch circumference is reduced after alignment so no problem in intermaxilla occlusal relationship must be confirmed. In case with crowding, judicious removal of interproximal enamel is indicated.

탁주의 소비증대와 저장성 및 품질 증진을 도모하고 기능성 탁주 개발을 위하여 감초(Glycyrrhiza uralensis) 추출물을 탁주에 첨가(0.005%, 0.05%, 0.5%)하여 저장성 및 품질 증진에 미치는 효과를 알아보았다. 탁주에 포함된 효모 등의 미생물은 첨가된 감초 추출물에 의해 저장 기간 중에 크게 변화를 받지 않으나 첨가하는 농도가 높아짐에 따라 약간의 감소현상을 보였다. 산화도는 추출물 첨가 농도가 증가함에 따라 감소되는 경향을 보여 산화방지에도 효과가 있는 것으로 나타났다. 당도는 저장 기간에 따른 유의적 변화를 보이지 않았으나 감초 추출물의 첨가 농도가 높을수록 당도가 높아져 기호성이 높아지는 원인이 되었다. 감초 추출물의 첨가량이 증가할수록 현탁 안정성이 높아져 0.5% 첨가 시 저장 전 기간 중 거의 완전하게 유지되었다. 감초 추출물 첨가구의 pH는 무첨가구에 비해 높고 안정하게 유지되었으나, 산도는 초기에 약간 감소하였다가 완만하게 증가하는 경향을 나타내었다. 명도와 황색도는 감초 추출물 0.5% 첨가구에서 높게 나타났으나 그 외의 첨가구에서는 거의 차이가 없었고, 적색도는 무처리구와 감초 추출물 첨가구간의 유의적인 차이가 없었다. 저장 9일차의 관능평가 결과, 감초 추출물 첨가구의 전체적인 기호도가 무처리구에 비해 높게 나타났다. 이상의 결과를 종합해 볼 때, 0.5%의 감초 추출물을 탁주에 첨가할 경우 무첨가구에 비해 최소 3일 이상 저장기간을 연장할 수 있을 것으로 생각되며, 기호성 증진에도 효과가 있으리라 사료된다. This study was performed to examine the properties of takju containing added Glycyrrhiza uralensis ethanol extract (GUEE) at 10℃ for 12 days. Change in TBARS values was lower in the takju with GUEE as compared to control. The total viable cell count and yeasts cell count of all samples remained constant over the storage period. The brix of the takju treated with 0.5% GUEE (3.8-4.3) was higher than that of the control (3.8-4.0). Suspension stability and yellowness increased as the added concentration of GUEE increased. After 12 days of the storage, the pH level of the 0.5% GUEE takju was 3.9, which was 0.2 higher than that of control. In terms of acidity, the 0.5% GUEE takju ranged from 0.269 to 0.282, whereas the acidity of the control ranged from 0.294 to 0.302. In treated Takju with GUEE represented at treated takju with GUEE had the positive effects toward improving its preservation and quality.

본 연구에서는 꽈배기모자반 물 추출물에 식품산업에서 사용이 확대되고 있는 감마선 조사기술을 이용하여 항산화능의 변화를 알아보고, 꽈배기모자반 물 추출물의 높은 점성과 짙은 색상으로 인한 문제점을 개선하고자 하였다. 꽈배기모자반 물 추출물의 감마선 조사에 따른 항산화능의 변화를 알아보기 위해 총 페놀화합물 함량을 측정하고 DPPH radical 소거능을 측정하였다. 그 결과, 3~20 kGy의 감마선을 조사한 꽈배기모자반 물 추출물은 조사선량이 증가할수록 총 페놀화합물 함량이 증가하였고, DPPH radical 소거능도 증가하여 감마선 조사에 의해 항산화능이 증진되었다. 그리고 꽈배기모자반 물 추출물에 감마선 조사 시 물리적 특성 변화를 알아보기 위해 색상과 점도를 측정한 결과, 감마선 조사선량이 증가할수록 색이 옅어지고 점성이 감소하는 것으로 나타났다. 이를 통해 꽈배기모자반 물 추출물에 감마선을 조사한 후 식품에 적용 시 가공특성을 개선시킬 수 있을 것으로 사료된다. 따라서 감마선 조사는 꽈배기모자반 물 추출물의 물리적 특성을 개선시키고 항산화능 또한 증진시키므로 식품산업에 적용 시 기존의 천연 항산화제의 단점을 개선시킬 수 있는 기술로서 사용이 확대될 수 있을 것으로 사료된다. In this study, the antioxidant properties and physical characteristics of irradiated Sargassum siliquastrum water extract were evaluated. Samples were irradiated with Co<SUP>60</SUP> γ-ray at doses ranging from 3 to 20 kGy. They were then analyzed to investigate antioxidant properties, including total phenolic compound content and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity. In addition, physical properties such as viscosity and color were evaluated. The results demonstrated that total phenolic compound content and DPPH radical scavenging activity were significantly improved (p<0.05) by irradiation. In terms of physical properties, viscosity and color were reduced in the irradiated extracts as compared to non-irradiated samples. In conclusion, gamma irradiation improved the antioxidant properties of Sargassum siliquastrum water extract, improving its original weak point as a natural antioxidant when applied in the food industry.

Park, Younghee,Kim, Kyung Su,Kim, Kyubo,Chie, Eui Kyu,Kim, Jin Ho,Kim, Jae-Sung,Kim, Tae Hyun,Kim, Dae Yong,Jang, Won Il,Kim, Mi-Sook,Koo, Tae Ryool,Chang, Ah Ram M. Nijhoff ; Kluwer Academic Publishers 2015 Journal of neuro-oncology Vol.125 No.2

<P>The incidence of brain metastasis from hepatocellular carcinoma (HCC) is increasing because of the improved survival outcome of HCC patients, but the prognosis of these patients is extremely poor. HCC patients with brain metastasis were investigated to identify their prognostic factors for overall survival. Patients with brain metastasis from HCC who had been treated with whole-brain radiotherapy (WBRT) in five hospitals were enrolled in the study. The medical records of the patients were reviewed, and the clinical factors were analyzed to identify the prognostic factors for overall survival. Of the total of 97 patients who were enrolled in the study, 83 were male and the median age at the brain metastases was 56.6??years. Motor weakness (43.3??%) and headache (41.2??%) were common presenting symptoms. The median AFP level was 4180??ng/ml, and 81 patients were assessed as belonging to Child-Pugh classification A upon the diagnosis of brain metastasis. WBRT alone in 71 patients, surgery or radiosurgery combined with WBRT as the adjuvant setting in 18 patients, and WBRT as salvage treatment in 8 patients were performed. The median overall survival of the patients was 3.5??months. In the multivariate analysis, the ECOG performance status (PS), Child-Pugh classification, AFP, and treatment aim showed significant association with the overall survival of the patients. Based on these factors, a nomogram predicting the prognosis was developed. The concordance index of the nomogram was 0.74, and the prediction was well calibrated. In conclusion, the survival outcome of patients with brain metastasis from HCC can be predicted with the nomogram constructed from the ECOG PS, Child-Pugh classification, AFP, and treatment aim.</P>

Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.

Estimation of model parameters and properties for numerical simulation on geomechanical stability of gas hydrate production in the Ulleung Basin, East Sea, Korea

Kim, Ah-Ram,Kim, Hak-Sung,Cho, Gye-Chun,Lee, Joo Yong Elsevier 2017 QUATERNARY INTERNATIONAL Vol.459 No.-

<P><B>Abstract</B></P> <P>The process of hydrate dissociation and production induced by depressurization incorporates intricate hydraulic, thermal, and mechanical phenomena. Thus, coupled thermal-hydraulic-mechanical (T-H-M) simulation is critically necessary to evaluate the geomechanical stability of hydrate production in hydrate-bearing sediments (HBS). However, methods of estimating the input model parameters and properties of the target reservoir, in particular in unconsolidated marine sediments, have received limited attention compared to studies on production simulators. The T-H-M properties of the marine sediments change considerably with depth, geological strata, and soil type of each layer. Therefore, it is important that representative layers and their corresponding T-H-M properties should be properly estimated to analyze the stability and productivity of methane gas recovery in the field. This study provides a comprehensive estimation for the model parameters and properties of unconsolidated marine sediments, based on vast data from field seismic surveys and laboratory experimental results with core samples, investigates empirical correlations between model parameters and methane hydrate saturation, and finally summarizes the estimated model parameters and properties, which can possibly be applied to on-going numerical research into stability assessment of the pilot gas hydrate (GH) production test, which is soon to be performed in the Ulleung basin.</P>

( Ah Ram Kim ),( Won Seob Shin ) 대한물리의학회 2014 대한물리의학회지 Vol.9 No.3

PURPOSE: The purpose of this study was to investigate the effects of high intensity intermittent training on cardiopulmonary capacity in canoe and kayak paddlers. METHODS: A total of 16 canoe and kayak paddlers were participated in this study. Experimental grou (n=8) was performed high-intensity intermittent training and control group(n=8) was moderate intensity training. All subjects performed a treadmill test in order to compare the difference before and after the intervention. Finishing the test, all subjects were measured to their heart rate(HR), forced vital capacit (FVC), forced expiratory volume in one second(FEV1) and forced expiratory ratio(FEV1/FVC). Recovery of heart rate(RHR) was calculated using the HR. HR and pulmonary flow values was measured before and during the intervention period per 2, 4, 6 and 8 weeks. To compare the differences over time between experimental group and the control group, used(time×group) two-way repeated measures ANOVA. One way repeated ANOVA was performed to determine where differences over time within-group. RESULTS: One-way repeated ANOVA revealed a significant difference in the experimental and control group. In experimental group, %RHR3min and FEV1 were significantly increased after 4 weeks(p<.05). Also, %RHR1min, FVC and FEV1/FVC were significantly increased after 6 weeks(p<.05). In control group, RHR1min, %RHR3min, FVC, FEV1 and FEV1/FVC were significantly increased after 6 week (p<.05). CONCLUSION: Not only moderate training but also high-intensity intermittent training contributes to cardiopulmonary capacity in canoe and kayak paddlers. Although high-intensity intermittent training is very short time, the training has high degree of efficiency. Therefore, developed this training in the future, it will be better to improve the cardiopulmonary capacity for athletes and healthy people.

Growth Responses and Flowering of Kalanchoe Cultivars under Elevated CO2Concentration and Varying Daylength

Ah Ram Cho,Hee Ji Yang,Euna Kim,Yoon Jin Kim 한국화훼학회 2020 화훼연구 Vol.28 No.1

본 실험은 CAM 식물인 칼랑코에(Kalanchoe blossfeldiana) 에 이산화탄소 시비 및 다양한 일장처리를 통한 생육반응을 조사하여 탄소자원화 기술 도입 방안을 모색하고 고품질 분화 묘 생산을 하고자 수행되었다. 실험은 서울여자대학교 ICT스마트형 유리온실에서 실시하였으며, 공시 재료는 칼랑코에 Kalanchoe blossfeldiana ‘Lion’, ‘Fikalrudak’ 두 품종이다. 일장은 8시간, 12시간, 16시간으로 처리하였으며 이산화탄소는 22:00~04:00에 평균 400㎛ol・mol-1(대조구)와 800㎛ol・mol-1로 처리했다. 엽수는 칼랑코에 ‘Lion’ 품종의 경우, 8시간과 12시간 일장에서, 칼랑코에 ‘Fikalrudak’ 품종의 경우, 8시간 일장에서 이산화탄소 농도 상승에 따라 증가하였다. 초장은 품종에 관계없이 일장 8시간에서 이산화탄소 농도를 400㎛ol・mol-1에서 800㎛ol・mol-1로 증가시킬 때 감소하였다. 칼랑코에 ‘Lion’ 품종에서, 미성숙엽의 엽장과 엽폭은 이산화탄소 농도 상승에 따라 일장 8시간과 12시간에서 증가하였다. 하지만, 칼랑코에 ‘Fikalrudak’ 품종의 미성숙엽 엽장과 엽폭은 이산화탄소 농도에 영향을 받지 않아 품종에 따른 반응 차이가 있는 것으로 판단된다. 마디수는 품종과 일장에 관계없이 이산화탄소 농도를 800㎛ol・mol-1로 증가시켰더니 증가하였으며, 개화소요일 수는 이산화탄소 농도에 영향을 받지 않았다. 개화는 품종에 따라 차이가 있었으며 칼랑코에 ‘Lion’ 품종에서는 8시간과 12시간 일장에서, 칼랑코에 ‘Fikalrudak’ 품종에서는 8시간 일장에서 나타났다. 이상의 결과로 칼랑코에는 이산화탄소 농도에 관계없이 단일 조건에서만 효과적으로 개화하며, 이산화탄소 시비는 칼랑코에 잎의 생산과 마디 생산을 촉진시킬 수 있었 다. 그러나 이산화탄소 고농도 시비는 칼랑코에 개화 품질에 부정적인 영향을 줄 수 있으므로 시비 단계, 품종 등에 따른 적합한 시비 방법이 다르게 적용되어야 한다. This experiment was conducted to identify the morphological characteristics of elevated atmospheric CO2 concentration of Kalanchoe blossfeldiana cultivars under different daylength treatments, in order to apply the carbon reduction method. CO2 treatment took place between 22:00 and 04:00 with an average of 400 μmol·mol-1 (control) and 800 μmol·mol-1 on Kalanchoe blossfeldiana ‘Lion’ and ‘Fikalrudak’. The photoperiod was controlled using an 8 h (08:00 to 16:00), 12 h (06:00 - 18:00), and 16 h (04:00 - 20:00) light-dark cycle. The number of leaves increased more in plants under the 800 μmol·mol-1 treatment than those in the control, with a photoperiod of 8 h and 12 h in both K. ‘Lion’ and 8 h in K. ‘Fikalrudak’. Plant height was lower in plants treated with 800 μmol·mol-1 CO2 than under the control treatment with an 8-h photoperiod of 8 h, regardless of K. blossfeldiana cultivars. In K. ‘Lion’, immature leaf length and width increased more in plants treated with 800 μmol·mol-1 CO2 than in the control, with a photoperiod of 8 h and 12 h. However, the leaf length and width of K. ‘Fikalrudak’ was not affected by CO2 concentration. The nodes were produced primarily by increasing CO2 concentration to 800 μmol·mol-1, regardless of daylength and K. blossfeldiana cultivars. Flowering time was not affected by daylength, however, K. ‘Lion’ bloomed within the photoperiod of 8 h and 12 h and K. ‘Fikalrudak’ bloomed only under a photoperiod of 8 h. K. blossfeldiana cultivars bloomed effectively under less light availability, regardless of CO2 concentration. These results showed that a CO2-rich enrichment promotes leaf and node production of Kalanchoe blossfeldiana cultivars under short-day conditions. Since high concentration of CO2 enrichment can have an adverse effect on flowering quality, appropriate CO2 enrichment methods for the developmental stage and cultivars should be applied on a case-by-case basis.
