박영은 ( Park Youngeun ),이우성 ( Lee Woosung ) 한국공간디자인학회 2021 한국공간디자인학회논문집 Vol.16 No.4

(연구배경 및 목적) 근린공원은 노인이 경제적 부담 없이 손쉽게 접근하여 다양한 신체활동을 실행할 수 있는 장소이며, 체력 증진 및 건강 유지가 이루어지는 도시시설이다. 그러나 우리나라의 많은 공원은 설계자의 주관적이고 일률적인 공원설계 기준에 의해 조성되어 있어 노인들이 이용하기에는 많은 불편함이 있다. 이에 본 연구는 노인들의 건강 유지 장소로서의 근린공원 이용 활성화를 위해 공원환경 평가지표를 선정하고, 대구광역시의 근린공원을 대상으로 평가지표를 적용하여 노인의 공원환경에 대한 인식을 분석하였으며, 노인의 개인적 특성에 따른 공원환경 인식의 차이를 탐색하였다. (연구방법) 연구대상지는 노인인구비율이 14% 이상인 대구광역시 중구, 동구, 남구, 서구를 대상으로 하였으며, 연구 대상공원은 행정구별 1개의 근린공원을 선정하였다. 공원환경 평가지표의 선정은 총 10편의 선행연구 고찰 및 브레인스토밍 과정을 통해 이루어졌으며, 설문조사는 노인들을 대상으로 2차에 걸쳐 진행되었다. 설문데이터의 분석에는 기술통계 및 빈도분석, T-검정 및 F-검정(Scheffe 검증)이 활용되었다. (결과) 노인의 관점에서 공원환경 관련 선행연구 고찰 및 브레인스토밍 과정을 통해 ‘다양한 운동시설’, ‘운동시설의 안전성’, ‘충분한 휴게시설’, ‘휴게시설의 안락함’ 등 총 20개 지표가 선정되었다. 설문에 의해 수집된 290개 데이터를 통해 노인의 공원환경 인식을 분석한 결과, ‘공원까지의 거리’, ‘충분한 녹지면적’, ‘충분한 그늘’, ‘이동의 무장애성’ 등의 지표가 4.0점 이상으로 높은 환경 수준을 가지는 것으로 분석되었다. 반면, ‘원예활동지원 공간’, ‘다양한 볼거리’, ‘복지시설과의 연계’ 등의 지표는 3.2점 이하의 낮은 환경 수준으로 평가되었다. 또한, 노인의 개인적 특성에 따른 공원환경 인식의 차이를 분석한 결과, 성별, 연령대, 교육수준, 소득수준에 따른 공원환경 인식의 차이가 통계적으로 유의하게 분석되었다. 남성보다 여성이 전반적인 공원환경을 긍정적으로 평가하였으며, 60대는 동적 시설에 대한 인식이, 80대는 정적 시설에 대한 인식이 높게 나타났다. (결론) 본 연구에서 도출된 결과들은 노인인구 밀집지역의 근린공원 리모델링 사업, 주변 환경 개선 사업 등을 진행코자 할 경우 의미 있는 기초자료가 될 것으로 판단된다. (Background and Purpose) Neighborhood parks are places where the elderly can easily access and perform various physical activities without without financial burden and are urban facilities where they can improve physical strength and maintain health. However, many parks in Korea are built according to the subjective and uniform design standards of the landscape designers, so there are many inconveniences for the elderly to use them. Therefore, the purpose of this study is to select the assessment indicators in order promote park use the elderly as a place for maintaining health, to analyze the perception of park environment by applying the indicators targeting the neighborhood parks of Daegu Metropolitan City, and to explore the differences in perception of park environment according to the individual characteristics. (Method) The study areas were Jung-gu, Dong-gu, Nam-gu, and Seo-gu of Daegu, where the ratio of the elderly population was 14% or more and one neighborhood park was selected for each administrative district. The assessment indicators of park environment were selected based on 10 previous studies and brainstorming and the questionnaire survey was conducted in two rounds for the elderly. Descriptive statistics, frequency analysis, T-test, and F-test (Scheffe’s method) were used to analyze the questionnaire data. (Results) Through the review and brainstorming related to the park environment from the perspective of the elderly, a total of 20 indicators were selected such as 'various exercise facilities', 'safety of exercise facilities', 'enough resting facilities', and 'convenience of resting facilities'. As a result of analyzing the perception of the elderly's park environment based on the 290 survey data, the indicators such as 'distance to the park', 'area of green space', 'shade by trees', and 'convenience of walk' had a high environmental level of 4.0 or more. On the other hand, the indicators such as 'horticultural support space', 'various attractions', and 'linkage with welfare facilities' were evaluated at a low environmental level of 3.2 points or less. In addition, as a result of analyzing the difference in perception of park environment according to the individual characteristics of the elderly, the differences according to gender, age group, education level, and income level were analyzed statistically significant. Women rather than men perceived the overall park environment more positively. Those in their 60s had positive perceptions of dynamic facilities and those in their 80s had positive perceptions of static facilities. (Conclusions) The findings from this study will be meaningful basic data to carry out a remodeling for a neighborhood park or a project for improving the neighborhood environment in the elderly concentration area.

박창용(Changyong Park),김남조(Namjo Kim),김상태(Sangtae Kim),최영은(Youngeun Choi) 대한지리학회 2014 대한지리학회지 Vol.49 No.5

본 연구에서는 치악산 국립공원을 사례로 TCI를 이용하여 관광기후환경의 변화와 미래 전망을 파악하였다. 과거와 미래를 포함하여 분석된 모든 기간에서 TCI 일평균값의 분포는 봄철과 가을철에 두 개의 봉우리가 나타나는 이봉형태가 나타났다. 따라서 치악산 국립공원은 봄철과 가을철에 관광하기 가장 적합한 기후로 파악되었다. 이러한 분포에는 주간 쾌적지수(Cid)와 일쾌적지수(Cia)의 요소인 기온과 습도가 주요한 영향을 미치는 것으로 분석되었다. 최근 들어 치악산 국립공원의 여름철 관광기후환경이 저하된 것으로 분석되었다. 이는 일조시간의 감소가 이에 가장 큰 영향을 미친 것으로 나타났다. 미래로 갈수록 여름철 관광기후환경의 저하는 더욱 심화될 것으로 전망되었다. 또한 연중 가장 낮은 TCI는 현재 겨울철에 나타났지만 미래에는 여름철로 변화할 것으로 분석되었는데 이는 세부지수 중 주간 쾌적지수(Cid)의 감소가 가장 큰 기여를 하였다. This study was aimed at examining the recent and the future changes of tourism climatic conditions for Chiaksan national park using TCI(Tourism Climate Index). The distribution type of daily mean of TCI showed the bimodal-shoulder peaks for all periods of the past and the future. Therefore, Chiaksan national park showed affordable climate of touring in spring and autumn due to temperature and relative humidity constituting Cid and Cia. Summer tourism climatic conditions of Chiaksan national park has become worse recently. In the future, these trends are projected more stronger. Also, the lowest TCI in the year is projected to shift from winter to summer due to a decrease of Cid.

Youngeun Han,Sangwook Park,Jongok Lim,Bongkyu Byun,Seunghwan Lee,Dongpyeo Lyu 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.05

Up to days, 15 species of the genus Xylotrechus, which have most diverse species among the tribe Clytini, have been recorded from Korean peninsula. The genus Xylotrechus can be distinguished from the other genera by combination of following characteristics: length of antennal socket longer than 1st segment of antenna; antennae reaches about 2/3 of elytra or less; carinae on frons well developed; 1st segment of hind tarsus 2 times longer than total length of 2nd+3rd segment; carinae on frons exceeding vertex; compound eye joined prothorax. In 2007, we collected a specimen which is belong to the genus Xylotrechus from Goyang-si, Gyeonggi province and we identified this specimen with Xylotrechus pavlovskii Plavilstshikov. Xylotrechus pavlovskii Plavilstshikov is easily distinguished from the congeneric species by following characteristics: femora black except basal half pale brown; antennal socket with yellow pubescence patch; pronotum black with distinct six yellow pubescence patches; elytra black with four pairs of yellowish linear pubescence patches except anterior 1/5 part reddish, apice blunt with inner and outer small sharpen projection. As a result of this study, we report this species for the first time from Korea with description and illustrations of diagnostic characters.

Purpose: Two years have passed since a level I trauma center was officially opened in the Gacheon Gil Hospital, South Korea. We analyzed 2014 and 2015 registered patient data from the Korean Trauma Data Base (KTDB) to identify trends in trauma patient care and factors that influence the quality of trauma care at the Gacheon Gil trauma center. Methods: Data was extracted from the KTDB included patient age, sex, systolic blood pressure at emergency room arrival, revised trauma score, injury severity score, trauma injury severity score, transfusion amount, and the cause of death was analyzed. Results: A total of 3269 trauma patients were admitted to our trauma center in 2014 and 3225 in 2015. Demographics and mechanism of injury were not significantly different between years. The severity of trauma injury was decreased in 2015 although the mortality rate was slightly increased. This requires further analysis. Conclusion: The aim of this study was to determine the general status and trends in trauma incidence and management outcomes for the Incheon area. We noted no significant changes in trauma status from 2014 to 2015. We need to collect and review trauma patient data over a long period in order to elucidate trauma incidence and management trends in the trauma field. Finally, studies using trauma patient data will indicate appropriate quality control factors for trauma care and help to improve the quality of trauma management. [ J Trauma Inj 2016; 29: 155-160 ]

Recognition of Transmembrane Protein 39A as a Tumor-Specific Marker in Brain Tumor

Park, Jisoo,Lee, Hyunji,Tran, Quangdon,Mun, Kisun,Kim, Dohoon,Hong, Youngeun,Kwon, So Hee,Brazil, Derek,Park, Jongsun,Kim, Seon-Hwan Korean Society of ToxicologyKorea Environmental Mu 2017 Toxicological Research Vol.33 No.1

Transmembrane protein 39A (TMEM39A) belongs to the TMEM39 family. TMEM39A gene is a susceptibility locus for multiple sclerosis. In addition, TMEM39A seems to be implicated in systemic lupus erythematosus. However, any possible involvement of TMEM39A in cancer remains largely unknown. In the present report, we provide evidence that TMEM39A may play a role in brain tumors. Western blotting using an anti-TMEM39A antibody indicated that TMEM39A was overexpressed in glioblastoma cell lines, including U87-MG and U251-MG. Deep-sequencing transcriptomic profiling of U87-MG and U251-MG cells revealed that TMEM39A transcripts were upregulated in such cells compared with those of the cerebral cortex. Confocal microscopic analysis of U251-MG cells stained with anti-TMEM39A antibody showed that TMEM39A was located in dot-like structures lying close to the nucleus. TMEM39A probably located to mitochondria or to endosomes. Immunohistochemical analysis of glioma tissue specimens indicated that TMEM39A was markedly upregulated in such samples. Bioinformatic analysis of the Rembrandt knowledge base also supported upregulation of TMEM39A mRNA levels in glioma patients. Together, the results afford strong evidence that TMEM39A is upregulated in glioma cell lines and glioma tissue specimens. Therefore, TMEM39A may serve as a novel diagnostic marker of, and a therapeutic target for, gliomas and other cancers.

GOLGA2 loss causes fibrosis with autophagy in the mouse lung and liver

Park, Sungjin,Kim, Sanghwa,Kim, Min Jung,Hong, Youngeun,Lee, Ah Young,Lee, Hyunji,Tran, Quangdon,Kim, Minhee,Cho, Hyeonjeong,Park, Jisoo,Kim, Kwang Pyo,Park, Jongsun,Cho, Myung-Haing Elsevier 2018 Biochemical and biophysical research communication Vol.495 No.1

<P><B>Abstract</B></P> <P>Autophagy is a biological recycling process via the self-digestion of organelles, proteins, and lipids for energy-consuming differentiation and homeostasis. The Golgi serves as a donor of the double-membraned phagophore for autophagosome assembly. In addition, recent studies have demonstrated that pulmonary and hepatic fibrosis is accompanied by autophagy. However, the relationships among Golgi function, autophagy, and fibrosis are unclear. Here, we show that the deletion of <I>GOLGA2</I>, encoding a cis-Golgi protein, induces autophagy with Golgi disruption. The induction of autophagy leads to fibrosis along with the reduction of subcellular lipid storage (lipid droplets and lamellar bodies) by autophagy in the lung and liver. <I>GOLGA2</I> knockout mice clearly demonstrated fibrosis features such as autophagy-activated cells, densely packed hepatocytes, increase of alveolar macrophages, and decrease of alveolar surfactant lipids (dipalmitoylphosphatidylcholine). Therefore, we confirmed the associations among Golgi function, fibrosis, and autophagy. Moreover, <I>GOLGA2</I> knockout mice may be a potentially valuable animal model for studying autophagy-induced fibrosis.</P> <P><B>Highlights</B></P> <P> <UL> <LI> GOLGA2/GM130 loss induces autophagy with Golgi disruption in liver cells and transgenic mice. </LI> <LI> GOLGA2/GM130 loss leads to degradation of lipid structures (LBs and LDs) by autophagy. </LI> <LI> GOLGA2/GM130 loss causes liver and lung fibrosis. </LI> </UL> </P>

Youngeun HAN,Jongok LIM,Sangwook PARK,Bongkyu BYUN,Seunghwan LEE,Dongpyeo LYU 한국응용곤충학회 2010 한국응용곤충학회 학술대회논문집 Vol.2010 No.05

Up to days, 5 species belonging to the genus Clytus, one of the large genera among the tribe Clytini have been recorded from Korean peninsula. The genus Clytus can be distinguished from the other genera by combination of following characteristics: width of head between each antennal socket longer than length of scape; carinae on frons absent; 1st segment of hind-tarsus 2 times shorter than combined length of 2nd+3rd segments; hind-femora weekly swelled in middle part; posterior part of metasternum without process in ventral view. Clytus sp. nov. is most similar to C. clavicornis Reiche, an endemic species to Sicily island in Southern Italy, having thickened 5th or 6th to apical antennal segment. However, this species can be distinguished from the latter species by specific morphological characteristics. As a result of this study, we report Clytus sp. nov. as new to science with brief description and illustrations diagnostic characteristics with key to the Korean Clytus species.

Traumatic lumbar hernia: clinical features and management

Youngeun Park,Min Chung,Min A Lee 대한외과학회 2018 Annals of Surgical Treatment and Research(ASRT) Vol.95 No.6

Purpose: Traumatic lumbar hernia is rare, thus making diagnosis and proper treatment challenging. Accordingly, we aimed to investigate the clinical manifestations and proper management strategies of traumatic lumbar hernias. Methods: The medical records of patients with traumatic lumbar hernia treated at Gachon University Gil Hospital from March 2006 to February 2015, were retrospectively reviewed. Results: We included 5 men and 4 women (mean age, 55 years; range, 23–71 years). In 8 patients, most injuries were caused by motor vehicle collisions, including those wherein a pedestrian was struck (5 cases of car accidents, 2 falls, and 1 involving penetrating materials); in 1 patient, the probable cause was severe cough. Eight patients underwent hernia repair surgery (5 open and 3 laparoscopic), and a prosthetic mesh was used in 7 patients. Hernia repairs were elective in 7 patients; emergency hernia repair was performed with right hemicolectomy in 1 patient. No severe complication or recurrence was observed. Only 2 patients had mild complications, such as postoperative seroma. Conclusion: Traumatic lumbar hernia is a relatively rare injury of the posteriolateral abdominal wall. Lumbar hernia should be suspected in patients with high-energy injuries of the torso, and all such patients should undergo abdominopelvic computed tomography. After diagnosis, hernia repair can be electively performed without complications in most cases.

Major Causes of Preventable Death in Trauma Patients

( Youngeun Park ),( Gil Jae Lee ),( Min A Lee ),( Kang Kook Choi ),( Jihun Gwak ),( Sung Youl Hyun ),( Yang Bin Jeon ),( Yong-cheol Yoon ),( Jungnam Lee ),( Byungchul Yu ) 대한외상학회 2021 大韓外傷學會誌 Vol.34 No.4

Purpose: Trauma is the top cause of death in people under 45 years of age. Deaths from severe trauma can have a negative economic impact due to the loss of people belonging to socio-economically active age groups. Therefore, efforts to reduce the mortality rate of trauma patients are essential. The purpose of this study was to investigate preventable mortality in trauma patients and to identify factors and healthcare-related challenges affecting mortality. Ultimately, these findings will help to improve the quality of trauma care. Methods: We analyzed the deaths of 411 severe trauma patients who presented to Gachon University Gil Hospital regional trauma center in South Korea from January 2015 to December 2017, using an expert panel review. Results: The preventable death rate of trauma patients treated at the Gachon University Gil Hospital regional trauma center was 8.0%. Of these, definitely preventable deaths comprised 0.5% and potentially preventable deaths 7.5%. The leading cause of death in trauma patients was traumatic brain injury. Treatment errors most commonly occurred in the intensive care unit (ICU). The most frequent management error was delayed treatment of bleeding. Conclusions: Most errors in the treatment of trauma patients occurred in early stages of the treatment process and in the ICU. By identifying the main causes of preventable death and errors during the course of treatment, our research will help to reduce the preventable death rate. Appropriate trauma care systems and ongoing education are also needed to reduce preventable deaths from trauma.
