두경부암 치료에 따라 발생한 흡인 환자에 대한 다각적 재활운동 치료

Patients who have the head and neck cancer are usually treated by surgery, radiation therapy, chemotherapy, or combinations of them. These treatments can induce variable degree of aspiration with dysphagia. The type and severity of aspiration depends on the size and location of the original tumor, the structures involved, and the treatment modality used for treatment. The management of aspiration after the head and neck cancer's treatment begins with an accurate evaluation for the cause and mechanism of aspiration through modified barium swallow (MBS) and fiberoptic endoscopic examination of swallowing (FEES). Then, the clinician can use postures, maneuvers, and exercises to treat the swallow disorder and to help the patient achieve optimal function. To achieve optimal swallowing without aspiration, multidimensional rehabilitation by various medical personnel is definitely necessary.

Background and Objectives : Provox, a recently developed tracheoesophageal prosthesis, had been widely used for voice rehabilitation after total laryngectomy for its low resistance and easiness of speech ability. But, long-term use of Provox resulted in many complications and resulted in cessation of Provox as a primary method of vocal rehabilitation. The aim of this study is to report Provox-related problems and the long-term results of Provox voice prosthesis. Materials and Methods : Medical records from patients who had undergone total laryngectomy with Provox insertion at seoul National University Hospital between January 1993 and December 1998 were reviewed retrospectively. Results : 36 patients had used 79 Provox voice prostheses during the observed period. The most common complication causing prosthesis change or removal was leakage and/or aspiration, followed by granulation formation, crusting and/or obstruction, and non-function. Median in situ lifetime of Provox was 274 days and 1-year-in situ rate was 31.0% Among 36 patients, 17 patients had undergone tracheoesophageal shunt closure at the last follow-up visit. 10 patients had complications but got along without further treatments, and 1 patient changed to Blom-Singer voice prosthesis. Only 8 patients experienced no complication, and 5 out of whom had several times of Provox change. Conclusion : long-term use of Provox resulted in discontinuation of its use due to complications in many cases. A better voice prosthesis with lower complication rate and longer in situ lifetime is needed.

This study was conducted to examine the vitality of Bletilla striata Rchb.f. seed treated with different concentrations sodium hypochlorite (NaOCl) for different lengths of time. This study also examined the effect of NaOCl treatment times and concentrations on swelling formation and seed germination of B. striata seed. The non-treated B. striata seed had the highest survival rate (82.7%) Treatment with more than 1.5% NaOCl negatively affected the seed survival rate, as compared to concentrations of less than 1%. The swelling formation and seed germination percentages were highest (90.1% and 94.1%, respectively) when seeds were treated with 0.5% NaOCl for 20 min. These results can be used as important basic data for the growth and restoration of B. striata and further suggest the possibility of individual restoration in habitats.

Purpose: Allergic diseases have been increased in Korea. The aim of this study was to investigate the changes of sensitization rate to inhalant allergens over 10 years in children with allergic diseases from a tertiary referral hospital. Methods: Skin prick tests were done in total 2,225 children in 2000, 2005, and 2010. Changes of skin reactivity to 12 major inhalant allergens, including Tree pollen mixture I (Alder, Elm, Hazel, Poplar, Willow), Tree pollen mixture II (Beech, Birch, Oak, Plane tree), Dermatophagoides pteronyssinus, Dermatophagoides farina, Alternaria, cat dander, and dog dander were investigated. Results: The sensitization rates to Tree pollen mixture I and II were increased as 5.0%, 6.8% in 2000, 8.5%, 9.8% in 2005, and 14.8%, 17.3% in 2010, respectively (trend P<0.001, P<0.001, respectively). And the sensitization rates to D. pteronyssinus cat dander and dog dander were changed as 55%, 4.8%, 4.8% in 2000, 62.2%, 11.9%, 28% in 2005, and 63.1%, 12.7%, 16.7% in 2010, respectively. The distribution of sensitized pollens was oak (12.8%), beech (12.4%), pine (10.3%), birch (10%), hazel (9.6%), alder (8%), elder (6.9%), elm (5.4%) in the study of 2010. When allergen/histamine ratio was compared, rates of strong sensitization over 4+ to tree pollen were increased. Conclusion: The sensitization rates to inhalant allergens were increased in children with asthma or allergic rhinitis from a tertiary referral hospital in Seoul over last 10 years. Especially, an increase in the degree of skin reactivity was observed in cat dander, dog dander, and tree pollens. The studies to investigate the etiology of this increase and prevention will be needed. (Allergy Asthma Respir Dis 2014;2:97-102)
증례보고 : Klippel-Feil 증후군 환자의 마취경험
정영호 ( Young Ho Jung ),유병훈 ( Byung Hoon Yoo ),이상석 ( Sang Seok Lee ),우승훈 ( Seoung Hoon Woo ) 대한마취과학회 2006 Korean Journal of Anesthesiology Vol.51 No.4
We present a 12-year-old female Klippel-Feil syndrome patient who underwent a surgical correction of thoracolumbar scoliosis. The patient had congenital fusion of the cervical vertebrae (C2,3,4,5,6) and showed the classic triad consisting of a low posterior hairline, short neck, and neck motion limitation. Because these patients may have a risk of neurological damage during airway management and subsequent positioning, anesthesiologists need to take care regarding the cervical spine pathology and degree of instability. In this case, fiberoptic bronchoscope guided intubation was performed. We discuss the anesthetic management of Klippel-Feil syndrome patients with a review of the relevant literature.

잠재성장모형을 이용한 청소년의 인터넷 이용유형이 학업성취도에 미치는 효과 분석
정영호(Jung, Young Ho) 사이버커뮤니케이션학회 2013 사이버 커뮤니케이션 학보 Vol.30 No.2
인터넷 이용과 학업성취도에 관한 연구는 아직까지도 일치된 결과를 보여 주지 못하고 있다. 이러한 결과는 기존 연구들이 이용시간이라는 중독증세에 집중하고 있고, 인터넷 이용의 시간 누적적 효과를 고려하지 않고 있기 때문이다. 따라서 이 연구에서는 장기간의 청소년 패널로 구성된 종단자료를 사용해 인터넷 이용시간과 함께 인터넷 이용유형을 정보추구형, 관계추구형, 오락추구형으로 구분한 후 학업성취도와의 관계를 잠재성장모형을 통해 살펴 보았다. 먼저 인터넷 이용시간은 학업성취도에 부정적인 영향을 미치는 것으로 나타났다. 다음으로 청소년의 인터넷 이용유형을 살펴보면, 정보추구형의 경우 초기치가 높을수록 학업성취도가 높았으며, 변화율이 증가할수록 학업 성취도의 하락율도 둔화되었다. 관계추구형의 초기치는 학업성취도의 초기치와 관계가 없었지만, 관계추구형 이용이 빠르게 감소할수록 학업성취도는 더디게 하락하였다. 한편, 오락추구형의 경우에는 초기치와 변화율 모두 서로 관계가 없는 것으로 나타났다. 결론적으로 인터넷 이용유형에 따라 학업성취도는 달라지고, 특히 관계추구형 이용이 학업성취도에 가장 나쁜 영향을 미친다는 사실을 확인하였다. A general consensus on Internet usage effects of academic achievement has been elusive, with great debate occurring among scholars in this field. That"s why existing researches have focused on the addiction like use hours and have not considered time cumulative effects. The current study analyzes the effects of both Internet use hours and Internet use type on academic achievement with latent growth model using longitudinal data to have time effect. At first, Internet use hours have the negative effects on academic achievement. In the case of Internet use type, students who had the higher initial state of information-seeking use have the higher initial academic achievement and their slopes have significant positive relation each other. While the intercept of the relationship-seeking use has no effects on the intercept of academic achievement, the slope of the relationship-seeking use affects academic achievement negatively. On the other hand, entertainment-seeking use has no relation to academic achievement from the intercepts and the slopes. In conclusion, the study shows the fact that academic achievement depends on using Internet type and, in particular, relationship-seeking use has the worst effect on academic achievement.
다양한 환경기울기에서 기온과 CO<sub>2</sub>농도 상승이 떡갈나무(Quercus dentata Thunb. ex Murray) 유식물의 생육에 미치는 영향
정영호 ( Young-ho Jung ),이재근 ( Jae-keun Lee ),김의주 ( Eui-joo Kim ),유영한 ( Young-han You ),채주리 ( Ju-ri Chae ),조규태 ( Kyu-tae Cho ) 한국환경생태학회 2018 한국환경생태학회 학술대회지 Vol.2018 No.1
이 연구는 떡갈나무(Quercus dentata Thunb. ex Murray)유식물을 대상으로 대기 중의 CO<sub>2</sub>농도와 기온이 상승하였을 때 광(L), 수분(M), 유기물(N) 그리고 토성(S)의 변화에 따라 생육이 어떻게 변하는지 알아본 것이다. 떡갈나무는 낙엽활엽교목으로 전국 표고 800m이하의 산기슭, 산중턱뿐 아니라 해변가의 야산이나 섬에도 잘 생육하며, 건조한 석회암 지역에서 우점종으로 분포하고 있다. CO<sub>2</sub>농도와 기온을 상승시킨 온난화처리구와 대기 중의 상태를 그대로 둔 대조구에서 광, 수분, 유기물 그리고 토성을 각각 4구배(1, 2, 3, 4)로 처리하였다. 각 구배 당 24개체씩 파종하여 2017년 3월부터 10월까지 8개월간 생육시킨 후 잎 수, 지하부/지상부 길이 및 무게, 잎자루/잎몸/잎폭 길이 및 무게 그리고 비엽면적 등 20가지 형질을 측정하였다. 측정한 20가지 형질은 온난화, 광, 수분, 유기물 그리고 토성 환경에 의한 생육반응에서 통계적인 차이가 있었다. 특히 지하부의 반응은 수분이나 토성 보다 광 조건에서 차이가 컸고, 이에 따라 식물체 무게와 지하부/지상부 비에도 영향을 주었다. 또한 잎면적은 모든 구배에서 대조구보다 처리구에서 높아지는 경향을 보였으며 특히 유기물을 처리하였을 때 대조구와 처리구 간의 통계적인 차이가 있었다. 이는 유식물이 지구온난화가 진행됨에 따라 광합성을 증가시키기 위한 적응으로 해석된다. 이 연구는 2017년 중견연구지원사업(NRF-2016R1A2B1010709)에 의하여 지원되었다.
