This article aims to examine the status of multicultural families in Korea from 2010 to 2020, while analyzing their problems and reasons from a multi-layered perspective, to provide an academic foundation for reference in supporting a social safety system for the stable settlement of those families. Although foreign immigrants experience a certain acceptance due to economic necessity, this attitude is often only a conditional and partial acceptance that does not consider migrants as full members of the community and, moreover, sometimes even suspects them of promoting social division through their presence. This study comprehensively analyzes the current status, problems, and causes of problems in multicultural families in Korea through related data between 2010 and 2020. The problems of multicultural families are manifested mainly in economic, cultural and social terms, and each of these problems is organically interconnected. International marriages between Korean men and female immigrants from developing countries are facing a special set of issues such as unequal status of the spouses or specific problems in child’s education. These problems are serious in the sense that they are not only a temporary burden for the multicultural families, but can also affect future generations, the chances of their development and their inclusion in society. Analysis of these problems, which lie in factors of the social environment and cultural differences, can serve as a basis for countermeasures that will benefit multicultural families in Korea. The problems of multinational families must be understood and addressed in their intertwined complexity in order to find solutions that benefit not only these families, but ultimately society as a whole.

Surgical Outcomes for Hepatocellular Carcinoma (HCC) with Portal Vein Tumor Thrombosis (PVTT-Vp3,4)

( Xuguang Hu ),( Heejung Wang ),( Bong-wan Kim ),( Ingyu Kim ),( Sung-yeon Hong ),( Xue-yin Shen ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

Aims: HCC patients with portal vein tumor thrombosis (PVTT) are classified into Barcelona clinic liver cancer (BCLC) stage C and have an extremely poor prognosis. The aim of the present study: To analyzed the long-term results of our series of patients with Vp3, 4 and try to find out the risk factors which can prognostic overall survival. Methods: From January 2003 to December 2014, a total of 810 cases of HCC were operated in our department. Among them, 52 cases were Vp3, 4 (6.4%). Six cases were excluded: Two cases of salvage liver transplantation, three cases of re-resection and one case of PVTT combined with IVC thrombosis. Finally, 46 cases with PVTT (Vp3, 4) were enrolled in the present study. The cutoff values of continues variables were decided by receiver operating characteristic (ROC) curve analysis. Univariate and multivariate regression analysis were performed to identify prognostic factors of overall survival. Results: The median survival time was 8 months in the present study. Most of the patients preserve the good liver function (child-Pugh stage A, 44/46) The 1-, 3-, and 5-year overall survival rated of all the Vp3, 4 patients in the present study were 52.4%, 32.7% and 26.2%, respectively. There were 16 cases (34.8%) suffered from PVTT recurrence after operation. The tumor size more than 6.5cm and postoperative PVTT recurrence were found to be independent risk factors for overall survival in multivariate regression analysis. Conclusions: In selected patients, surgical treatment can achieve a relatively good outcome with 1-year survival rate of 52.4%. Tumor size was an independent prognostic factor for overall survival for HCC patient with Vp3, 4. Postoperative PVTT is another risk factor for overall survival and the HCC patients with PVTT should be strictly monitored for PVTT recurrence after operation.

CC - NUMA 시스템에서의 프로세싱 노드간 네트워크 부하 분석

김태균(Taegyoun Kim),왕희정(Heejung Wang),이강우(Kangwoo Lee) 한국정보과학회 2000 한국정보과학회 학술발표논문집 Vol.27 No.2Ⅲ

CC-NUMA 시스템은 SMP 시스템의 장점인 프로그래밍의 편리함, 작업 환경의 유연함 및 관리의 용이함 등을 유지하는 한편, SMP의 단접이었던 확장성까지 제공한다. 더욱이 메모리 장벽 즉 급격히 빨라지는 프로세서의 처리 속도에 비해 메모리의 속도는 거의 변화가 없음으로 인하여 야기되는 문제를 극복할 수 있는 구조적인 대안으로 각광 받고 있다. 이러한 CC-NUMA 시스템은 노드간의 논리적인 거리가 길기 때문에 프로세싱 노드간의 통신이 시스템의 성능에 영향을 미치는 가장 핵심 요소가 된다. 따라서 노드간의 통신을 최소화 해주기 위한 노력으로 각 노드에 장착되어지는 원격 캐쉬의 중요성이 강조된다. 본 논문에서는 CC-NUMA 시스템에서의 노드간 데이터 통신의 유형을 파악하고, 원격 캐쉬의 블록 사이즈에 따른 이들이 발생횟수의 변화를 분석하였다. 인스트럭션 시뮬레이터인 CacheMire와 SPLASH II 벤치마크 중 하나인 FFT를 이용하여 실행-구동 시뮬레이션을 통해 원격캐쉬 블록의 크기가 증가할수록 노드간 통신의 횟수는 물론 전송되는 데이터의 절대적인 양이 감소한다는 사실을 알 수 있었다.

( Xu-guang Hu ),( Heejung Wang ),( Bowon Kim ),( Sung-yeon Hong ),( Mina Kim ) 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: Multiple primary malignancies are defined as two or more different malignancies detected synchronously or metachronously in different organs of an individual patient. The aim of the present study was to investigate the clinicopathologic features for the HCC patients with multiple primary malignancies. Methods: Between May 1997 and July 2016, 1043 HCC patients had been received radical surgical treatment in our institute. Among them 58 (5.6%) cases were diagnosed with extra-hepatic primary malignancies. The clinicopathologic features including Age, Sex, HBs Ag (positive), HCV Antibody (positive), AFP(more than 400ng/ml), tumor size (more than 5cm), multiple tumor number, microvascular invasion, Edmondson grade (grade 3 and 4), cirrhosis (fibrosis stage 4), AJCC staging for HCC (Stage 1). All the data were retrospectively analyzed form the database of our institute which were prospectively collected. Results: The median follow up time is 53 months in the present study. Of the 58 (5.6%) multiple malignancies patients, 8 were diagnoses synchronously and 50 metachronously; 14 patients’ extra hepatic primary malignancies occurred prior to their HCC diagnoses, and 36 after their HCC diagnoses.The 5 years OS rate for multiple and single primary tumor were 77.8% and 66.9%, respectively (P=0.036). The multiple primary tumor patients have the following clinicopathologic features: older mean age, more patients with non-viral background liver, fewer patients with liver cirrhosis and more patients with AJCC stage I for HCC. Conclusions: The patients with multiple primary tumors have a relatively good prognosis in our institute mostly due to the factors of non-viral background liver and early tumor stage.

Sangwon Kim,Mison Chun,Heejung Wang,Sungwon Cho,Young-Taek Oh,Seung-Hee Kang,Juno Yang 대한암학회 2007 Cancer Research and Treatment Vol.39 No.3

Purpose: To assess the characteristics of bone metastasis from hepatocellular carcinoma and the radiation field arrangement based on imaging studies.Materials and Methods: Fifty-three patients (84 lesions) with bone metastasis from a primary hepatocellular carcinoma completed palliative radiation therapy. All patients underwent one of following imaging studies prior to the initiation of radiation therapy: a bone scan, computed tomography or magnetic resonance imaging. The median radiation dose was 30 Gy (7∼40 Gy). We evaluated retrospectively the presence of soft tissue formation and the adjustment of the radiation field based on the imaging studies.Results: Soft tissue formation at the site of bony disease was identified from either a CT/MRI scan (41 lesions) or from a symptomatic palpable mass (5 lesions). The adjustment of the radiation field size based on a bone scan was necessary for 31 of 41 soft tissue forming lesions (75.6%), after a review of the CT/MRI scan. The median survival from the initial indication of a hepatoma diagnosis was 8 months (2 to 71 months), with a 2-year survival rate of 38.6%. The median survival from the detection of a bone metastasis was 5 months (1 to 38 months) and the 1-year overall survival rate was 8.7%.Conclusion: It was again identified that bone metastasis from a primary hepatocellular carcinoma is accompanied by soft tissue formation. From this finding, an adjustment of the radiation field size based on imaging studies is required. It is advisable to obtain a CT or MRI scan of suspected bone metastasis for better tumor volume coverage prior to the initiation of radiation therapy. (Cancer Res Treat. 2007; 39:104-108)

Joohyun Sim,Jaeheon Lee,John Cook-Jong Lee,Yunjung Heo,Heejung Wang,Kyoungwon Jung 대한외과학회 2015 Annals of Surgical Treatment and Research(ASRT) Vol.89 No.4

Purpose: This study aimed to determine the mortality rate in patients with severe trauma and the risk factors for trauma mortality based on 3 years’ data in a regional trauma center in Korea. Methods: We reviewed the medical records of severe trauma patients admitted to Ajou University Hospital with an Injury Severity Score (ISS) > 15 between January 2010 and December 2012. Pearson chi-square tests and Student t-tests were conducted to examine the differences between the survived and deceased groups. To identify factors associated with mortality after severe trauma, multivariate logistic regression was performed. Results: There were 915 (743 survived and 172 deceased) enrolled patients with overall mortality of 18.8%. Age, blunt trauma, systolic blood pressure (SBP) at admission, Glasgow Coma Scale (GCS) at admission, head or neck Abbreviated Injury Scale (AIS) score, and ISS were significantly different between the groups. Age by point increase (odds ratio [OR], 1.016; P = 0.001), SBP ≤ 90 mmHg (OR, 2.570; P < 0.001), GCS score ≤ 8 (OR, 6.229; P < 0.001), head or neck AIS score ≥ 4 (OR, 1.912; P = 0.003), and ISS by point increase (OR, 1.042; P < 0.001) were significant risk factors. Conclusion: In severe trauma patients, age, initial SBP, GCS score, head or neck AIS score, and ISS were associated with mortality.
