A Brief Discussion on the Method of Cultural Infiltration in College Korean Teaching

DONG YI 한국유통과학회 2014 한국유통과학회 학술대회 논문집 Vol.2014 No.-

At present, many colleges and universities in China offer Korean courses. However, teachers attach more attention to the Korean grammar and language knowledge in the process of teaching. They don't sufficiently realize the importance of Korean culture. In order to further improve the teaching effects and make students learn authentic Korean language, it is necessary for the college educators to highlight the cultural infiltration inthe process of college Korean teaching.

Purpose: The aim of this study was to retrospectively evaluate contrast-enhanced ultrasound (CEUS) findings in patients with peliosis hepatis (PH). Methods: A retrospective analysis was conducted of CEUS features in 24 patients with histopathologically confirmed PH (11 men and 13 women; mean age, 32.4±7.1 years; range, 28 to 41 years). All lesions were histologically proven, either by core needle biopsy (n=10) or by hepatic surgery (n=14). Results: The mean size was 36.8±12.4 mm (range, 10 to 80 mm). On B-mode ultrasonography (BMUS), all PH lesions were heterogeneously hypoechoic, with well-defined margins but irregular shapes. No mass effect was observed. During the arterial phase of CEUS, all lesions displayed mild heterogeneous hyperenhancement (83.3%, 20/24) or isoenhancement (16.7%, 4/24). Furthermore, 87.5% of the PH lesions showed mild washout after 1 minute in the portal venous phase (30-120 seconds) and mild washout in the late phase (>120 seconds). Conclusion: The lack of a mass effect on BMUS, mild heterogeneous arterial hyperenhancement, and washout in the very late portal venous phase (after 1 minute) on CEUS are characteristic of PH. Although it is a histological diagnosis, PH should be considered in the differential diagnosis when the clinical context does not favor a malignancy or infection.

A Comparative Study on Spiritual Culture Education of Women College Campus between China and Korea

Dong Yi 동아시아경상학회 2015 The East Asian Journal of Business Economics Vol.3 No.4

The Spiritual culture education is not only the nucleus of campus culture but also the ultimate aim of the construct ion of campus culture. Currently the construction of campus culture is understood and implemented in the view of pragmatism and utilitarian, but the value- oriented role of college spirit is belittled, which leads to the absence of specific purpose and direction. If universities and colleges want to remain invincible, they must attach the importance to the spirit culture, the systematic culture, the material culture and the behavioral culture, and in all, the college spirit. Based on the current ideological educational situation of women’s vocational colleges, a research has been conducted on how to play the educational functions of campus culture, seeking for the integration of campus culture and spiritual culture and, achieving talents cultivation objectives on the campus. This paper analyses and compares the influencing factors in Spiritual culture education between China and Korea women university from the following parts: The campus environment, campus material, campus system, campus behavior and diversified thinking challenge. Backed with the findings of the research, it offers some suggestions on the developing ideas and models of characteristic campus culture construction for women’s colleges between China and Korea.

Inverse system optimal control of interleaved boost converters

Dongyi Xiao,Yimin Lu 전력전자학회 2022 JOURNAL OF POWER ELECTRONICS Vol.22 No.6

When compared with the conventional boost converter, the interleaved boost converter (IBC) has the advantages of low current stress. Thus, they have been widely used in DC microgrids. However, the IBC is a multiple input single output (MISO) high-order nonlinear system. To simplify the controller design, a reduced order model of an interleaved boost converter is proposed in this paper. By selecting an appropriate output function, the nonlinear reduced order system is transformed into a pseudo-linear system through the inverse system theory. Then an optimal controller is designed based on the linear quadratic regulator (LQR) theory. As a result, the output voltage can track the reference value. In addition, a current balance controller is designed to balance the interphase inductor current. Simulation results of a 3-phase IBC show that when compared with PI control, the proposed control strategy has better regulation performance. Finally, the correctness and eff ectiveness of the proposed control strategy are further verifi ed by experiment on 2-phase IBC.

Li, Dongyi,Lu, Kun,Cheng, Yong,Zhao, Wenlong,Yang, Songzhu,Zhang, Yu,Li, Junwei,Wu, Huapeng Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.7

The motion control of the divertor maintenance system of the China Fusion Engineering Test Reactor (CFETR) was studied in this paper, in which CFETR Multi-Functional Maintenance Platform (MFMP) was simplified as a parallel robot for the convenience of theoretical analysis. In order to design the motion controller of parallel robot, the kinematics analysis of parallel robot was carried out. After that, the dynamic modeling of the hydraulic system was built. As the large variation of heavy payload on MFMP and highly nonlinearity of the system, A Fuzzy-PID controller was built for self-tuning PID controller parameters by using Fuzzy system to achieve better performance. In order to test the feasibility of the Fuzzy-PID controller, the simulation model of the system was built in Simulink. The results have showed that Fuzzy-PID controller can significantly reduce the angular error of the moving platform and provide the stable motion for transferring the divertor.

The structure design of divertor Multi-Functional Maintenance Platform (MFMP) actuated by hydraulic system for China Fusion Engineering Test Reactor (CFETR) was introduced in this paper. The model of MFMP was established according to maintenance requirements. In this paper, Newton-Euler method and the improved virtual work principle were used, the equivalent driving force of each actuator was obtained through the equivalent Jacobian inverse matrix derived from velocity relationship among the components. The accuracy of the model was verified by ADAMS simulation. The stability control of the heavy-duty components driven by hydraulic cylinders based on Newton-Euler method and improved virtual work principle was established.

기능성 위장장애 환자의 소화불량 제증상 치료에 있어서 콤비짐^(�)정의 임상효과

김동의,주재환,추상우,김형륵,조철균,김영진,김현종,김신곤 中央醫學社 1996 中央醫學 Vol.61 No.12

Functional dyspepsia has been considered, until recently, to be a nebulous syndrome, in part because of the lack of a structural explanation for the symptoms and because of the apparent heterogeneity of the patients labeled with this diagnosis. Although many definitions have been offered, there is now reasonable consensus that dyspepsia refers to persistent or recurrent pain or discomfort that is centered on the upper abdomen ; the discomfort may be characterized by postprandial fullness, early satiety, nausea or upper abdominal bloating. The diagnosis of dyspepsia must not be restricted to those with meal-related symptoms because there is no clinical condition, including chronic peptic ulceration, in which the symptoms are exclusively confined to the postprandial period. The majority of the patients with chronic or recurrent dyspepsia do not have a peptic ulcer or any other recognized structural or biochemical abnormality that definitely explains the symptoms ; these patients are classified as having functional dyspepsia. Ideally, therapy for functional dyspepsia should be targeted at correcting an individual's underlying pathophysiologic disturbances. However, the mechanisms that produce symptoms in patients with functional dyspepsia remain poorly understood. A polyvalent digestive product Combizym� has a powerful combination of enzymes with broad activity and broad pH spectrum. It acts from the stomach to the small intestine and has a complete digestive effect on protein, carbohyrate and fat. We treated Combizym� in patients with functional dyspepsia with open, noncomparative study. The results are as follows ; 1. The improvement of the symptoms were 96.4 % in nausea and vomiting, 92.6 % in bloating, other symptoms were also improved over 75 %. 2. There was only mild pruritus in a patient and others were well tolerated during the experiment. 3. Overall improvement rate was 86.7 % of 30 patients. In conclusion, Combizym� is a safe and effective digestive drug in patients with functional dyspepsia.
