Hematoma-Filled Pneumatocele after CT-Guided Percutaneous Transthoracic Needle Lung Biopsy: Two Case Reports

Se Ri Kang 대한영상의학회 2023 대한영상의학회지 Vol.84 No.1

CT-guided percutaneous transthoracic needle biopsy (PTNB) plays a key role in the diagnosis of pulmonary abnormalities. Although the procedure is considered safe and effective, there exists a potential for complications, such as pneumothorax, hemorrhage, hemoptysis, air embolism, and tumor seeding. However, pneumatoceles after CT-guided PTNB have been rarely reported. Herein, we report two cases of pneumatoceles that developed immediately after PTNB for primary lung cancer. A pneumatocele filled with hematoma should be considered in cases with a newly developed nodule along the needle tract during short-term follow-up CT after PTNB.

Cerebral Air Embolism: a Case Report with an Emphasis of its Pathophysiology and MRI Findings

Kang, Se Ri,Choi, See Sung,Jeon, Se Jeong Korean Society of Magnetic Resonance in Medicine 2019 Investigative Magnetic Resonance Imaging Vol.23 No.1

Cerebral air embolism (CAE) is a rare complication of various medical procedures. It manifests with symptoms similar to those of typical acute cerebral infarction, however the treatment is quite different. We present a case of arterial CAE that was associated with a disconnected central venous catheter and appeared as punctate dark signal intensities with aliasing artifacts on the susceptibility-weighted filtered phase magnetic resonance image. The susceptibility-weighted filtered phase image can be helpful for diagnosing CAE and the magnetic resonance imaging reflects the pathophysiology of CAE.

Progressive Massive Fibrosis Mimicking Lung Cancer: Two Case Reports with Potentially Useful CT Features for Differential Diagnosis

Se Ri Kang,Ji Young Rho 대한영상의학회 2022 대한영상의학회지 Vol.83 No.5

Progressive massive fibrosis (PMF) with atypical findings is often misdiagnosed as lung cancer. Atypical features of PMF have been described in some reports; however, these reports only introduced their cases with a short literature review. We report two cases of solitary PMFs with no underlying simple pneumoconiosis or rapid growth at atypical location that were mistaken for lung cancer. We also suggest the useful CT findings to aid in the differential diagnosis.

Aims: To investigate correlation between hepatic venous pressure gradient (HVPG) and transient elastography (TE) in patients with cirrhosis and to identify a cut-off value of TE to HVPG in clinically significant portal hypertension (CSPH, HVPG ≥10mmHg) and severe portal hypertension (SPH, HVPG >12mmHg) according to the cause of cirrhosis. Methods: Between January 2008 and March 2017, 553 patients who underwent HVPG and TE were consecutively enrolled at the three Korean tertiary medical centers. HVPG and TE were performed within 1 month interval. Patients were classified with the cause of liver cirrhosis, and the cut-off value of TE was analyzed for patients with alcoholic and viral origin of cirrhosis. Results: The mean age was 53.3±9.8 years, and the majority (81.6%) were male. A significant positive correlation was noted between liver stiffness and HVPG levels (r=0.544, P<0.001). The area under receiver operating characteristic curves for TE to diagnose CSPH and SPH were 0.829 (95%CI: 0.790-0.868) and 0.80.2 (95%CI: 0.765-0.840). Among all cause of liver cirrhosis, the most common etiology was 1)alcohol 335(60.6%) followed by 2)chronic hepatitis B(CHB) 128(23.1%), 3)CHB with alcohol 45(8.1%), 4)cryptogenic 22(4%), 5)chronic hepa-titis C(CHC) 18(3.3%), and 6)CHC with alcohol 5(0.9%). HVPG and TE values were evaluated for total patients, patients with alcoholic(1), and viral [(2)+(5)] cirrhosis. In total patients, a cut-off values of TE of 27.6 and 32.5kPa were obtained by using Youden index to best predict CSPH and SPH, respectively. In alcoholic cirrhosis, a cut-off values of TE were 32.2 kPa and 36.6 kPa, for CSPH and SPH, respectively. In viral cirrhosis, a cut-off values of TE was 18.0 kPa for both CSPH and SPH(Table 1). Conclusions: In the alcoholic cirrhosis, cut off value of TE was higher than that of viral cirrhosis. Therefore, it is necessary to interpret the TE value depending on the cause of liver cirrhosis.

( Se Ri Ryu ),( Jeong-ju Yoo ),( Seong Hee Kang ),( Soung Won Jeong ),( Moon Young Kim ),( Young Kyu Cho ),( Young Chang ),( Sang Gyune Kim ),( Jae Young Jang ),( Young Seok Kim ),( Soon Koo Baik ),( 대한간학회 2021 Clinical and Molecular Hepatology(대한간학회지) Vol.27 No.1

Background/Aims: The hepatic venous pressure gradient (HVPG) reflects portal hypertension, but its measurement is invasive. Transient elastography (TE) is a noninvasive method for evaluating liver stiffness (LS). We investigated the correlation between the value of LS, LS to platelet ratio (LPR), LS-spleen diameter-to-platelet ratio score (LSPS) and HVPG according to the etiology of cirrhosis, especially focused on alcoholic cirrhosis. Methods: Between January 2008 and March 2017, 556 patients who underwent HVPG and TE were consecutively enrolled. We evaluated LS, LPR, and LSPS according to the etiology of cirrhosis and analyzed their correlations with HVPG. Results: The LS value was higher in patients with alcoholic cirrhosis than viral cirrhosis based on the HVPG (43.5 vs. 32.0 kPa, P<0.001). There were no significant differences in the LPR or LSPS between alcoholic and viral cirrhosis groups, and the areas under the curves for the LPR and LSPS in subgroups according to HVPG levels were not superior to that for LS. In alcoholic cirrhosis, the LS cutoff value for predicting an HVPG ≥10 mmHg was 32.2 kPa with positive predictive value (PPV) of 94.5% and 36.6 kPa for HVPG ≥12 mmHg with PPV of 91.0%. Conclusions: The LS cutoff value should be determined separately for patients with alcoholic and viral cirrhosis. In alcoholic cirrhosis, the LS cutoff values were 32.2 and 36.6 kPa for predicting an HVPG ≥10 and ≥12 mmHg, respectively. However, there were no significant differences in the LPR or LSPS between alcoholic and viral cirrhosis groups. (Clin Mol Hepatol 2021;27:197-206)

정세리(Se-ri Jung),강현주(Hyun-Joo Kang) 글로벌지식융합학회 2019 지식융합연구 Vol.2 No.2

본 연구는 문헌연구를 이론적 토대로 삼아 사회통합프로그램 5단계 ‘한국사회 이해(기본)’과정을 이수하거나 학습 중인 학습자를 대상으로 서술형 설문방법을 병행하여 법무부 사회통합프로그램 5단계 ‘한국사회이해(기본)’과정을 이수하였거나 학습 중인 학습자를 대상으로 서술형 설문문답을 실시한 결과 현재 사회통합프로그램 5단계 ‘한국사회 이해(기본)’과정은 다음과 같은 문제점으로 개선 방향을 제시하고자 한다. 주민들이 사회통합프로그램 5단계 ‘한국사회 이해(기본)’수업을 학습하고 이수 후 제공하는 혜택을 받고 있지만 사회통합프로그램이 한국 정착생활에 도움을 주는 부분은 미비하며 실질적으로 한국생활에 가장 도움이 되는 것은 한국어이며 사회통합프로그램 5단계 ‘한국사회 이해(기본)’수업에서 내용의 문법과 어휘가 학습하기 어려워 이해가 힘들며, 이주민들의 의사소통의 말하기 유창성의 부족과 한국인교사와 공무원들의 인종차별적 인식으로 인해 불편함을 겪고 있다. 또한 사회통합프로그램 5단계 ‘한국사회 이해(기본)’수업을 학습할 수 있는 시간과 장소가 한정되어있으며 교육시간이 부족하여 사회통합프로그램 5단계 ‘한국사회 이해(기본)’수업의 배정된 시간은 50시간이며, 이 시간 동안 50단원을 학습하여야 하는데 시간에 비해 방대한 ‘한국사회 이해(기본)’과정의 학습내용을 학습자들이 이해하고 활용하기에는 어렵다는 문제점이 나타났다. Recently, immigrants who are staying in Korea have been dominant Because the number of immigrants settling in Korea grows, discussion respecting the diversity of immigrants has gradually been increased. Currently, the score for the issuance of new visas is determined on qualifications of residence, permanent residence, and naturalization. Therefore, the number of immigrants who wanted to participate in the Korean Immigration and Integration Program (KIIP) that could get the additional points has been increasing, when issuing visas. The purpose of this study was to advance Understanding Korean society (basic) , operated by Ministry of Justice, consisted of KIIP 5th Step, which is providing necessary information for residence and settlement in Korea (This study will apply Understanding Korean society (basic) , operated by Ministry of Justice, consisted of KIIP 5th Step as Understanding Korean society (basic) . A result of analyzing the research participants shown that step of fluent Korean actually helps Korean life. However, grammar and vocabulary learning were difficult, so it was difficult to understand the contents of the text. And the ability to use what i have learned in everyday life was insufficient Moreover, life of Korea was hard because of their racist attitude of Koreans.

디자인 공유 플랫폼 유형 및 사례 분석

이세리(Lee, Se Ri),강태임(Kang, Tae Yim) 한국디자인문화학회 2018 한국디자인문화학회지 Vol.24 No.3

최근 디지털 기술의 발달로 소비자와 전문가들이 정보를 공유하고 협업하는 플랫폼이 활성화되면서 정보의 공유뿐 아니라 협업을 통한 경제활동까지 이루어지고 있다. 이와 같은 시대적 변화와 방식은 4차 산업혁명 시대를 맞이하면서 디자인 산업의 역할도 커지고 있고, 새로운 패러다임에 대응하기 위해 여러 측면에서 공유 플랫폼 구축의 필요성이 대두되고 있다. 그러므로 디자인 산업에서도 새로운 변화의 흐름에 맞는 안정된 디자인 공유 플랫폼이 필요하다. 본 논문은 포털사이트의 검색을 통해 사용자 수와 매출액 등 활성화를 기준으로 국내외 사례 7곳을 선정하였다. 선정된 사례분석을 위해 관련 문헌 자료 조사를 기반으로 공유 플랫폼의 개념과 현재 구현된 디자인 공유 플랫폼의 유형과 현황을 파악하였다. 선행연구 자료를 토대로 사례분석의 기준을 인터페이스, 인지도, 전문성, 편리성, 수익성, 신뢰성으로 제시하였다. 그리고 공유 디자인 플랫폼 사례의 특성이 어떻게 나타나는지 고찰하고 그 함의를 도출하였다. 국내외 사례 분석을 한 결과 수익성과 신뢰성이 높게 평가되었으며 전문성, 인터페이스, 인지도, 편리성순으로 평가되었다. 따라서 수익성과 신뢰성이 중요한 평가 기준이라고 볼 수 있다. 해외 사례에서 신뢰성과 수익성이 높게 평가되었고 이에 비해 국내 사례는 수익성과 전문성이 높게 평가되었다. 그리고 인지도가 높은 사례들이 더불어 신뢰성도 높게 평가되었다. 분석된 플랫폼 사례에서 수익성의 평가는 비교적 높았으나 해외 성공사례인 킥스타터(KickStarter)의 사례와 비교하여 국내 사례들은 신뢰성이 비교적 낮게 평가되어 국내 디자인 공유 플랫폼의 활성화를 위해서는 신뢰성을 보완해야 한다. By virtue of recent development of digital technologies, platforms that consumers and experts cooperate for some purposes have been widely spreaded. In addition to the information sharing and cooperation, commercial activities has been performed in those platforms. As a result, this trend has been adopted to design industry. Moreover, the role of design industry is by degrees expanded in the era of 4th industrial revolution. As a response of this situation, sharing platform has been become influential. So, a design sharing platform that is stable and in tune with the flow of an era is needed. This paper selected 7 domestic and foreign cases by searching portal sites in terms of upsweep. To analyze the selected cases, literature survey was done on the concept and the current status of sharing platforms. Based on it, the interface, awareness, convenience, professionalism, profitability, and reliability were presented as criteria. Moreover, the feature of sharing platform and its implication was investigated. As a result of analysis, profitability and reliability were highly rated. The order of criteria is professionalism, interface, awareness, and convenience. So, profitability and reliability are an important criterion. As to foreign cases, profitability and reliability were rated highly. On the other hand, professionalism and profitability were rated highly as to domestic cases. Moreover, the higher the awareness, the higher the reliability. The domestic cases were rated relatively high in terms of profitability, but rated low in terms of reliability, compared to Kickstarter as a foreign case. So, the reliability should be enhanced in order to boost the domestic design sharing platforms.
