본 연구는 중국에서의 한국어 교육의 발전 과정을 살펴보고 교육 현황을 점검하며 앞으로의 발전 방향을 가늠하는 데에 목적을 두고 있다. 논문의 1장에서는 중국에서의 한국어 교육의 발전 과정을 초창기(1945년~1972년), 침체기(1972년~1992년), 도약기(1992년~2002년), 성장기(2002년~현재)로 나누어 중국에서의 한국어 교육이60년 동안 어떻게 발전되어 왔는지에 대하여 간단하게 살펴보았다. 이런 고찰을 통하여 그동안 중국에서의 한국어 교육은 양적인 면에서나 질적인 면에서 모두 비약적인 발전을 해 왔고 괄목할 만한 성과를 거두었다는 사실을 알 수 있다. 논문의 2장에서는 한국어 교육의 외적 측면과 한국어 교육의 내적 측면으로 나누어 중국에서의 한국어 교육의 현황과 문제점에 대하여 논의하였다. 교육의 외적 측면에서 볼 때 현 단계의 한국어 교육은 정규 교육과 비정규 교육이 병행되는 것이 분명하다는 점, 내부적으로 지역별 편차가 크고 지역별 상황도 다르다는 점, 중국내 한국어 교육 학계와의 협력, 한국과의 협력이 아직까지 체계적이지 못하다는 점 등 세 가지 특징을 띠고 있다는 결론을 추려낼 수 있다. 그리고 한국어 교육의 현황과 문제점을 교육의 내적 측면, 즉 교육과정론, 교사론, 교재론, 교수학습론, 평가론 등의 관점에서도 살펴보았다. 논문의 4장에서는 앞서 서술한 내용을 바탕으로 향후 중국에서의 바람직한 한국어 교육 발전을 위하여 한국어 교육학의 학문적 토대 구축, 한국어 교육의 다양화 지향, 한국어 고급 인재의 양성, 한국어 교사 자질의 향상, 한국어 교육ㆍ연구 역량의 결집 등 다섯 가지 제안을 하였다. 本研究的主要目的是追溯中国韩国语教育的发展过程, 考察韩国语教育现状, 并指出今后的发展方向。 在论文的第二章中, 将中国韩国语教育的发展历程分为初创期 (1945年~1972年), 停滞期(1972年~1992年), 飞跃期(1992年~2002年)、成长期(2002年~现在)四个阶段, 通过考察得知在过去的六十年间中国的韩国语教育在质与量上都得到了长足发展, 取得了许多令人瞩目的成果。在论文的第三章中, 从教育的外部因素及内部因素两个方面对中国韩国语教育的现状与问题做了具体阐述。从教育外部因素来看, 现阶段的韩国语教育有正规教育与非正规教育并行、各地区存在着明显的不平衡、国内的协作及与韩国的协作尚不活跃等特点。本文还从教育的内部因素, 即课程设置与课程标准论、教师论、教材论、教授学习论、评价论等方面对现今韩国语教育的现状与问题做了简要剖析。论文的第四章主要在上述内容的基础上, 提出了加强韩国语教育学学术基础的建设、谋求韩国语教育多元化发展、培养高级韩国语人才、提高韩国语教师素质、促进韩国语教育、研究力量协作等促进今后中国韩国语教学发展的五种方案。

The final samples consisted of 413 Korean and 402 Chinese students in high school. Results were as followed. Firstly, for Korean and Chinese students, maximizing tendency, regret, happiness and school adjustment showed significant correlations among each other. Secondly, there were significant differences on maximizing tendency, regret, happiness and school adjustment between Korean and Chinese students. Korean students` maximizing tendency, regret, happiness, and school adjustment were higher than Chinese students. As results of multi-group analysis, the influence of maximizing tendency on regret, and the influence of regret and happiness on school adjustment were stronger in Korean high school students group than Chinese high school students group. While, the influence of regret on happiness was stronger in Chinese students group than Korean students group. Implications of the study were discussed in depth.

Angelica Sinensis Polysaccharide Induces Erythroid Differentiation of Human Chronic Myelogenous Leukemia K562 Cells

Wang, Lu,Jiang, Rong,Song, Shu-Dan,Hua, Zi-Sen,Wang, Jian-Wei,Wang, Ya-Ping Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9

Leukemia is a clonal disorder with blocked normal differentiation and cell death of hematopoietic progenitor cells. Traditional modalities with most used radiation and chemotherapy are nonspecific and toxic which cause adverse effects on normal cells. Differentiation inducing therapy forcing malignant cells to undergo terminal differentiation has been proven to be a promising strategy. However, there is still scarce of potent differentiation inducing agents. We show here that Angelica sinensis polysaccharide (ASP), a major active component in Dong quai (Chinese Angelica sinensis), has potential differentiation inducing activity in human chronic erythro-megakaryoblastic leukemia K562 cells. MTT assays and flow cytometric analysis demonstrated that ASP inhibited K562 cell proliferation and arrested the cell cycle at the G0/G1 phase. ASP also triggered K562 cells to undergo erythroid differentiaton as revealed by morphological changes, intensive benzidine staining and hemoglobin colorimetric reaction, as well as increased expression of glycophorin A (GPA) protein. ASP induced redistribution of STAT5 protein from the cytoplasm to the nucleus. Western blotting analysis further identified that ASP markedly sensitized K562 cells to exogenous erythropoietin (EPO) by activating EPO-induced JAK2/STAT5 tyrosine phosphorylation, thus augmenting the EPO-mediated JAK2/STAT5 signaling pathway. On the basis of these findings, we propose that ASP might be developed as a potential candidate for chronic myelogenous leukemia inducing differentiation treatment.

Design of Space Search-Optimized Polynomial Neural Networks with the Aid of Ranking Selection and L2-norm Regularization

Dan Wang,Sung-Kwun Oh,Eun-Hu Kim 대한전기학회 2018 Journal of Electrical Engineering & Technology Vol.13 No.4

The conventional polynomial neural network (PNN) is a classical flexible neural structure and self-organizing network, however it is not free from the limitation of overfitting problem. In this study, we propose a space search-optimized polynomial neural network (ssPNN) structure to alleviate this problem. Ranking selection is realized by means of ranking selection-based performance index (RS_PI) which is combined with conventional performance index (PI) and coefficients based performance index (CPI) (viz. the sum of squared coefficient). Unlike the conventional PNN, L2-norm regularization method for estimating the polynomial coefficients is also used when designing the ssPNN. Furthermore, space search optimization (SSO) is exploited here to optimize the parameters of ssPNN (viz. the number of input variables, which variables will be selected as input variables, and the type of polynomial). Experimental results show that the proposed ranking selection-based polynomial neural network gives rise to better performance in comparison with the neuron fuzzy models reported in the literatures.

Dan Yang Wang,Jian Jiang Lin,Xiang Ming Xu,Fan Long Liu 대한외과학회 2013 Annals of Surgical Treatment and Research(ASRT) Vol.85 No.3

Purpose: To compare and assess the efficacy, safety and utility of hand-assisted laparoscopic surgery (HALS) with open surgery (OS) in total colectomy with ileorectal for colonic inertia. Methods: From January 2001 to February 2012, 56 patients diagnosed with colonic inertia who failed to respond to medical treatments underwent hand-assisted laparoscopic total colectomy with ileorectal anastomosis. Another 68 patients underwent laparotomy. Main parameters such as clinical manifestations, conversion to open procedure, operative time, incision length, pain score, intraoperative blood loss, time to first flatus and hospitalization, early postoperative complications and hospitalization cost were retrospectively analyzed. Postoperative defecating frequencies were followed up in both groups. Results: All patients received successful operation, no surgical mortality happened and none of the patients required conversion to an exploratory laparotomy in HALS group. The clinical features, the estimated blood loss, incision length, pain score, first passing flatus time, and postoperative hospitalization time were superior in HALS group (P < 0.05). The early postoperative complications and frequency of defecation were similar. However, the mean operative time was longer and hospitalization cost was higher in HALS group than those in OS group (P < 0.05). Conclusion: HALS total colectomy can be a safe and efficient technique in the treatment of colonic inertia. HALS can result in a better cosmetic result and a quicker postoperative recovery, but requires higher direct cost.

Cutaneous metastasis: a rare phenomenon of colorectal cancer

Dan Yang Wang,Feng Ye,Jian Jiang Lin,Xiao Xu 대한외과학회 2017 Annals of Surgical Treatment and Research(ASRT) Vol.93 No.5

Cutaneous metastases from colorectal cancer are extremely rare and generally appear several years after diagnosis or resection of the primary tumor. Although this phenomenon is uncommon, it is very important and often indicates a poor prognosis. We present a case of a 76-year-old female patient with multiple cutaneous metastatic nodules on the back, just 1 month after resection of rectal cancer. Unfortunately, the patient gave up the follow-up treatment due to her age and poor physical condition; she died 3 months later. In view of its rarity of occurrence and lack of experience in treatment, we reviewed the literature and report as follows.

Adaptive Pinning Synchronization of Complex Networks with Negative Weights and Its Application in Traffic Road Network

Dan Wang,Wei-Wei Che,Hao Yu,Jia-Yang Li 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.2

As local traffic congestion and uncertainty factors existing on roads may lead to cascading failures or even large area traffic network congestion, a pinning control method is proposed to divert the traffic and then restore the smooth flow of traffic. To eliminate the impacts of uncertainties and negative weights for the traffic network performance, the adaptive pinning control and coupling adjustment strategies are designed to estimate controller parameters and adjust coupling strength to compensate for the impacts on the pinned nodes and unpinned nodes. Based on Lyapunov stability theory, adaptive pinning controllers and network adjusters are developed to guarantee the achievement of network synchronization even in the presence of the uncertainties and negative weights. In addition, we investigate the effects of the type of nodes on pinning synchronization performance. Numerical simulations show that if the network’s degree and the single node energy index are considered, better synchronization performance can be obtained by comparing with the pervious pinning schemes.
