Purpose Radial probe endobronchial ultrasound (RP-EBUS) accurately locates peripheral lung lesions (PLLs) during transbronchial biopsy (TBB). We performed an updated meta-analysis of the diagnostic yield of TBB for PLLs using RP-EBUS to generate recommendations for the development of the Korean Association of Lung Cancer guidelines. Materials and Methods We systematically searched MEDLINE and EMBASE (from January 2013 to December 2022), and performed a meta-analysis using R software. The diagnostic yield was evaluated by dividing the number of successful diagnoses by the total lesion number. Subgroup analysis was performed to identify related factors. Results Forty-one studies with a total of 13,133 PLLs were included. The pooled diagnostic yield of RP-EBUS was 0.72 (95% confidence interval [CI], 0.70 to 0.75). Significant heterogeneity was observed among studies (χ2=292.38, p < 0.01, I2=86.4%). In a subgroup analysis, there was a significant difference in diagnostic yield based on RP-EBUS findings (within, adjacent to, invisible), with a risk ratio of 1.45 (95% CI, 1.23 to 1.72) between within and adjacent to, 4.20 (95% CI, 1.89 to 9.32) between within and invisible, and 2.59 (95% CI, 1.32 to 5.01) between adjacent to and invisible. There was a significant difference in diagnostic yield based on lesion size, histologic diagnosis, computed tomography (CT) bronchus sign, lesion character, and location from the hilum. The overall complication rate of TBB with RP-EBUS was 6.8% (bleeding, 4.5%; pneumothorax, 1.4%). Conclusion Our study showed that TBB with RP-EBUS is an accurate diagnostic tool for PLLs with good safety profiles, especially for PLLs with within orientation on RP-EBUS or positive CT bronchus sign.

중국 도시 토지제도 개혁과 지방정부 행위분석: 토지사용권 양도시장을 중심으로

伴隨着改革開放步伐的加快, 中國城市發展的速度擧世劇目。1988年土地有償使用制度的建立, 爲中國城市發展提供了制度基礎與保障。本文槪括改革期中國城市土地産權制度以及土地市場的特征而分析圍繞城市土地使用權出讓交易展開的中央與地方政府之間的博혁。作爲土地使用權交易場所, 城市土地使用權交易市場具有地方政府壟斷的屬性。改革期中國地方政府不僅像其他國家那樣扮演行政服務的提供者角色, 地方政府企業家一樣, 追求自己利益的經濟實體。中國地方政府利用土地市場上優勢地位, 追求"土地預算外收入"導致土地亂開發等問題。中央政府爲閼制地方政府的這些行爲, 土地交易中引進來市場机制。同時, 中央還采取了土地管理體制中强化省級人事管理權和監督權的措施。特別是在以胡錦濤爲中心的新國家領導人就任之后, 中國政府把"科學發展觀"和"和諧社會建設"作爲新的國家政策理念。這是對過去"先富起來"爲方鍼的增長發展觀的一大調整。胡錦濤執政后半期, 可能主要公共政策措施集中在土地治理中, 但是沒有根本改變1994年分稅制改革以來地方政府財事不均衡基本情況, 這些措施會導致中央與地方之間新的博혁關系。爲了深入探討中國城市土地治理現象, 需要包括房地産企業, 市民, 農民等社會領域里行爲者的進一步的調硏。

Comparison of Immediate Effectiveness between Forward and Backward Walking on Treadmill Training by Measuring Muscle Recruitments, Gait Parameters, and Dynamic Balance

김수한,주성광,박세연 국제물리치료연구학회 2022 Journal of International Academy of Physical Ther Vol.13 No.1

Background:Although several studies have reported functional improvements after forward walking training on a treadmill and after backward walking training on a treadmill, there is a lack of immediate effects data, investigating spatiotemporal parameter, neuromuscular recruitment. Objectives: To compare the immediate effects between forward and backward walking on treadmill training, present study measured muscle activities of the lower extremity, gait parameters, and dynamic balance. Design: Cross-sectional study Methods: The twenty-four asymptomatic young male subjects were participated in this study. Subjects have performed 15-min of forward and backward walking on treadmill. Before and after treadmill walking, the gait parameters were measured with the GAITRite. The dynamic balance abilities were assessed with the Y-balance test. Muscular activities were collected from the tibialis anterior, gastrocnemius, biceps femoris, and rectus femoris during forward and backward walking. Results: Muscular activities of the biceps femoris and tibialis anterior were significantly different between forward and backward walking conditions, which were higher with the backward walking (P<.05). Compared to the pre-measurement, the normalized dynamic balance composite score of the post-measurement was significantly higher with the backward walking (P<.05). Regardless of the treadmill training method, there were no significant differences between pre and post measurement, both the stride length and step length (P>.05). Conclusion: The performing backward walking training has positive effects for dynamic balance.

The Effect of NH3 Plasma Treatment on Low Dielectric Organosilicate Thin Film

김수한,한준희,차국헌 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.1

Mechanical properties of low dielectric organosilicate films are very important since it should withstand severe processing conditions imposed by Chemical Mechanical Planarization (CMP) Processing. Surface hardness is critical in terms of CMP compatibility of low-k films. In present study, NH3 plasma treatment was applied to organosilicate films to improve micromechanical properties of the film surface by forming densified surface layer. Improvement of surface hardness was measured using depth-sensing indentation with continuous stiffness mode (CSM). Although this improves surface hardness, but a densified surface layer also increases the effective dielectric constant of film. To balance these two effect, it is very important to control the thickness of densified surface layer precisely. To reach this goal, it is also essential to develop an accurate analytic technique to measure the thickness of densifed surface layer. We used X-ray reflectivity, FE-SEM and Auger electron spectroscopy to measure the depth profile of NH3 plasma treated dielectric film.

We evaluated 104 patients of neurogenic bladder secondary to traumatic spinal cord injury. Those were diagnosed by I.V.P. and V.C.U. at Korea Veterans Hospital during 9 years from Jan., 1978 to May, 1978. The type of neurogenic blader, complications and rethral configuration, according to the level of spinal cord injury were discussed. RESULTS : 1. The incidence of patient according to the level of spinal cord injury was 49 out of 104 in those with vertebral level T7 or above, 15 out of 104 in those with T8-T10 level, and 40 in those with vertebral level T11 or velow. 2. Overall incidence of urinary tract calculus was 32.7%. 3. Overall incidence of vesicoureteral reflux was 23.1%. 4. Overall incidence of pyelonephritis was 26.9%. 5. Overall incidence of hydronephrosis was 20.2%. 6. Almost entire urethra was shown funnel type in 66 out of 73 cases. Saccular dilatation of posterior urethra was 7 cases.

중국 동북 지역발전과 산업 특징에 관한 연구 -성별 산업특화도(LQ) 비교 분석

랴오닝(遼寧), 지린(吉林), 헤이룽장(黑龍江)으로 구성되어 있는 중국 동북지역은 글로벌 금융위기 이후의 경기침체를 극복하고 지역경제 활성화를 위한 다각적 노력을 기울이고 있다. 또한 문재인 정부의 <신북방정책> 및 <한반도신경제구상>과 밀접한 연관성을 갖는 동북3성은 한국의 동북아 번영·평화구상 추진의 핵심 지역으로 그 전략적 가치가 증대되고 있다. 동북아 신성장거점이자 전략적 요충지로 발돋움하고 있는 중국 동북지역 현황 파악과 발전 전망을 위한 기초 조사를 통해, 중국 동북 지역과의 교류·협력 강화를 위한 토대자료를 제공한다. 이 연구에서는 동북 지역이 하나의 일체화된 공간을 구성하고 있는 것이 아니라는 점을 보다 강조한다. 유사한 근대화 경험과 산업구조를 갖추고 있지만 환발해권역에 입지해 있는 랴오닝성과 내륙의 지린성·헤이룽장성은 경제 규모는 물론 산업구조 고도화 수준의 차이가 크다는 점을 연구를 통해 다각적으로 제시한다. 이를 위해 동북지역을 구성하고 있는 각성의 산업 특화 정도를 비교 검토한다. 본 연구는 향후 동북지역 발전의 동력 역할을 할 수 있는 지역을 판별할 수 있는 근거 자료를 제공한다는 점에서 연구 의의가 있다. 在世界金融危机后,为克服中国辽宁、吉林、黑龙江构成的东北地区的经济停滞 ,促进区域经济活力,进行了多方努力。文在寅政府的《新北方政策》和《韩半岛经济构想》密切相关的东北三省是促进东北亚繁荣·和平构想的核心地区,战略价值逐步增大。东北地区作为东北亚经济新增长点和战略要地,本研究希望能够通过基础调查掌握其现状及未来发展趋势,提供强化交流·合作的基础性资料。 本研究进一步强调,东北地区并非构成一个一体化的空间。虽然有着类似的近代化史和产业结构,通过研究提出辽宁、吉林、黑龙江的经济规模以及产业结构高度化程度有很大的差异。为此通过比较东北地区各省的产业特化程度,提供筛选出今后可以作为东北地区发展的的主要增长动力的依据。
