Workable Solutions to Improve the Profitability of Chinese Banks : Some Experience from Korea

Shu, Yuan Chen 고려대학교 국제대학원 2008 국내석사

This thesis discusses about several of the possible solutions to improve the profitability of Chinese banks based on some experience from the Korean banking industry. The legacy of the Chinese banking system left from the old centrally planned economic system has been a major reason that caused Chinese banks to be unprofitable. This has become a tough barrier for China to sustain a rapid economic growth while it embraces a new era of financial globalization. Due to the similarities in economic development based on cultural characteristic, the Korea banking industry before the Asian financial crisis shared some same problems with the Chinese banking industry at present. Combining the current status of Chinese banking industries and experience from Korea, some solutions are put forward to restructure banking and improve such business sectors as corporate finance and consumer credit.

본 논문은 중국으로 유입되는 외국인 여행객수가 중국 수출에 미치는 영향을 실증분석을 통해 살펴보았다. 이를 위해, 2000년부터 2015년까지 104개국으로 부터 중국을 방문한 외국인 관광객을 대상으로 관광객 입국자수, GDP, 환율, 인구 등의 데이터를 활용하여 중력 모형을 기반으로 세가지 방법으로 실증분석을 하였다. 우선, 최소자승추정법(OLS)을 사용하여 분석을 하였는데, 이 방법론에서는 중국의 수출이 방중 여행객수에 영향을 줄 수 있기 때문에 내생성 문제가 발생할 수 있고 또한 데이터로는 관찰되지 않은 시간 및 국가의 이질성 때문에 누락 변수 (omitted variable) 편의(bias)가 야기 될 수 있다. 이러한 문제를 다루기 위해 본 논문에서 도구 변수(IV)방법론 및 고정 효과를 사용하여 결과를 추가로 검증하였다. 본 논문의 분석결과에 따르면 세 가지 방법론에서 모두 방중 외국인 여행객수는 중국의 수출에 긍정적인 효과를 가져오며 그 결과는 모두 통계적으로 유의한 것으로 나타났다. 특히 고장 효과 방법론에 따르면 방중 여행객수가 1% 증가하면 중국의 상대국에 대한 수출은 0.25% 증가하는 것으로 나타났다. 이러한 본 논문의 결과는 지속적으로 증가하고 있는 방중 관광객이 중국 수출에 주요 원인임을 시사하고 있다.

Flows of fluids and suspensions in porous walled tubes

Chen, Shu-Chen Yu Northwestern University 2000 해외박사(DDOD)

The flow of pure fluids or suspensions in porous walled tubes is complicated by the interplay between the axial fluid mechanics and the radial flow driven by the transwall pressure difference. The present work is a theoretical investigation of these flows for pure fluids, concentrated suspensions of single sized particles, and suspensions of large, concentrated particles plus small, sparsely concentrated particles. A mathematical model, which takes into account shear-induced migrations for the suspensions, is developed and finite difference methods are used to solve the equations. For flows of pure fluids, the major aspect for the crossflow filtration is the amount of filtration. The effects of various parameters on filtration and the resulting velocity profiles are investigated. Both the velocity profiles and filtration rates agree reasonably with those by Yuan & Finkelstein (1956), Weissberg (1959), and Apfel (1990). For flows of concentrated suspensions with single sized particles, the filtration and shear enhanced diffusion, SED, affect the particle and velocity distributions. The effects of various parameters on filtration, SED, and the resulting particle distributions are studied. The results show that the ratio of tube to feed concentrations, the classical Fahraeus effect in blood flow, depends on tube length. A minimum tube length of 50 cm is suggested for obtaining a length-independent ratio. The present profiles are qualitatively similar to those by Koh, Hookham & Leal (1994) and Nott & Brady (1994) with the characteristics of velocity blunting and high concentrations near the tube center. For flows of suspensions with two particle sizes, the present study shows that the small particles are mostly concentrated near the wall where the large particles are sparse, agreeing with the observations of Waters & Eckstein (1990). The deposition of the small dilute particles inside the tube increases with increased SED and filtration. The study also demonstrates that the particles retained inside the porous tube may have very different distributions depending on their relative sizes and concentrations. By utilizing these differences in particle distributions, crossflow filtration potentially can be used to separate particles of different sizes.

현대적인 네이게이션 장치에도 불구하고 지리적 구조, 물속의 장애물, 바다 교통상황의 동적특성, 그리고 교통환경의 영향과 같은 문제가 존재한다. 비록 모든 선박들이 현대적인 네비게이션 장치가 설치 되어져 있지만, 조사에 따르면 인적요소로 인해 발생되는 다양한 원인으로 사고가 보고된다. 해양사고를 감소시키고 해양교통의 안정을 증가시키기 위해 연구에서는 작업의 효율성을 증가시키고 인간의 단점을 극복하기 위해 자동화 작동 시스템을 제안 하였다. 자동화 선박 네비이게이션을 위한 시뮬레이선시스템은 운영계획 및 수로의 설계 연구를 위한 강력한 도구가 될 수 있다. 이러한 시뮬레이션 시스템의 자율적인 충돌위험 계산과 충돌회피의 주요 작업은 인간의 개입을 최소화하여 프로그램 스스로 수행 한다. 유사한 자동 네비게이션 시스템은 인간의 개입없이 안적정이고 효율적인 자동화 네비게이션을 수행 할 수 있도록 설계되어지며, 일정상황에서 사람한테 최적의 코스를 제공한다. 이 논문은 충돌가능한 상황에서 선박의 충돌 가능성을 찾고 충돌을 회피하기 위한 효율적이고 실용적인 혼합 위험도 계산 방법을 제시하고 있다. 이 알고리즘은 구현이 간단하고 복잡한 향해 상황에서 선박을 효율적이고 자동으로 다뤄준다. 자동화선박 네비게이션의 세 가지 주요 제안은 현재 시간의 혼합 충돌 위험도 계산, 다음 시간의 혼합 위험도 예측과 충돌을 피하기 위한 선박 제어가 있다. 첫 번째 우리는 선박 위치 기반의 혼합 위험도 계산 방법을 제시한다. 이 방법은 퍼지와 퍼지 종합 평가 방법을 결합하여 기존의 충돌 위험도 계산 방법보다 정확도 가 더 높다. 두 번째 이 혼합 위험도 계산을 확장하고 칼만필터를 사용해서 다음시간 스템프에 선박의 위치를 예측하고 다음 시간 스템프에 혼합 충돌 위험도를 계산한다. 마지막으로 현재 시간의 혼합 위험도와 다음 시간의 혼합 위험도를 비교해서 충돌을 미리 피할 수 있도록 한다. 다음 시간의 위험도가 높으면 시스템은 항해자에게 적시에 선박을 제어하기 위한 속도와 각도등의 메시지를 보내준다. 항해자는 이 메시지를 확인해야 하고 만약에 향해자의 반응이 없으면 시스템은 중요한 순간에 자동으로 충돌 방지 조치나 기타 합리적인 운영을 채택하게 될 것이다. 또한, 제안된 시스템은 얼마나 많은 각도로 선박의 방향을 효율적으로 제어할지 결정할 수 있는 능력이 있다. Despite of modern navigation devices, there are still problems in navigation of vessels in waterways due to the geographical structures, disturbances in water, dynamic nature of the sea traffic, and heavily influenced environmental traffic. Even though all vessels are equipped with modern navigation devices, the accidents are reported caused by various reasons mainly by human factor according to investigation. To decrease the accident and increase the safety of sea traffic, researchers proposed an automatic maneuvering system to overcome the human’s shortcoming and increase work efficiency. Simulation system for automatic ship navigation can be a powerful tool for operational planning and design studies of waterways. In such a simulation system the key tasks of autonomous collision risk calculating and collision avoidance are performed by the simulation program itself with no or minimum intervention of a human navigator. This is in many ways similar to automatic navigation systems in that they are designed to carry out autonomous navigation safely and efficiently without the need for human intervention or to offer advice to the navigator regarding the best course of action to take in certain situations. This thesis presents an effective and practical hybrid collision risk calculation method for finding the collision probability and avoiding the collision for ships in possible collision situations. The algorithm is straightforward to implement and is shown to be effective in automatic ship handling for ships involved in complex navigation situations. We proposed three key task in this thesis; hybrid collision risk calculation at current time, hybrid collision risk prediction at next time and intelligent controller to avoid collisions. Firstly, we proposed a hybrid collision risk calculation method at ship’s position using combination of fuzzy and fuzzy comprehensive which is more accurate than existing method by simulation results. Secondly, we extend this hybrid collision risk calculation method to predict the location of ship at next time stamp using Kalman Filter and calculate the hybrid collision risk at next time stamp. Finally, we compared the hybrid collision risk and prediction hybrid collision risk so that the ships collision could be avoided more efficiently and effectively. When the collision risk is higher in next time stamp the system will send message to the navigator to timely control the ship navigation i.e. angle and speed etc. The navigator must affirm the messages, if there is no affirmation, the system will adopt collision avoidance measures or other rational operations automatically at the critical moment. Additionally, our proposed system also has the decision making capability that how much angle a ship should be deflect to effectively control the ship.

1920, 1930년대는 한국과 중국에도 특별한 시기였고, 양국 문학사에도 특별한 의미가 있었다. 일본 파시스트 제국의 야심은 점차 확장되었다. 이 특별한 시기에 양국의 문인들은 나라의 운명을 위해 붓을 무기로 택했고 많이 문학 작품을 썼다, 나라의 광대한 인민 대중으로부터 인민의 영혼을 일깨움으로써 나라를 깨웠다.흙 상록수 광인일기가 대표적이다. 작가들은 민족의 활로를 찾기 위해 매일 끊임없이 고민한다. 이 작품들은 당시 양국 문인들의 민족 부흥에 대한 생각을 잘 보여준다. 당시 사회 배경에서 두 나라의 문인들이 민족을 위해 기울인 노력과 땀도 잘 드러난다. 이 세 작품을 분석해 두 나라가 당시 사회환경에서 어떤 계몽주의를 탄생시켰는지, 또 계몽주의가 당시 사회환경과 문단에 어떤 영향을 미쳤는지, 그리고 후대의 문화에 어떤 영향을 미쳤는지를 짚어본다. 당시 사회환경 속에서 양국의 문인들이 어떤 사고를 갖게 됐는지 살펴보고, 그런 사고방식에서 민족의 구망을 위한 방법을 어떻게 모색해 나갈 것인가 하는 과정과 결과를 살펴본다. 두 나라 문인들의 서로 다른 환경에서의 서로 다른 사고방식과 계몽사상을 살펴본다. 주제어: 계몽소설. 한국. 중국. 반붕건. 근대

A Study on Visitors' Motivations and Satisfactions : Focused on Jeju National Museum

Chen, Shu-Yun 제주대학교 대학원 2009 국내석사

Museums are a type of cultural attractions with unique features and are increasingly being used as instruments for promoting tourism and boosting the regional economy. In order to better understand the museum market and achieve better service, the main objective of this study, based on earlier studies, is to examine whether the demographic characteristics of museum visitors made any significant differences to the motivations and satisfactions toward their museum experience. Jeju National Museum was chose to be the research site for being the only national cultural museum with large scale in Jeju. The choice of a single center for the collection of data was an attempt to place the research in a similar context for all visitors, so that any possible influence of contextual factors on variables studied could be avoid. A total of 274 samples were collected for a period of 3 weeks, from November 3 to November 19 2008, during the opening hours of the museum, by using survey method with self-administered survey questionnaire. Frequency, factor analysis, t-tests and ANOVA were utilized to analyze the collected data. The results of factor analyses identified five push factors domains and three pull factor domains underlying respondents' ratings. Satisfaction factors were developed by asking visitors to evaluate the degree of accomplishment of their expectation. It was found out that there were significant differences between/among gender, age, education background and place of residence in terms of motivations and satisfactions toward museum experience. The research also revealed that knowledge seeking, among other oush motivational dimensions, is the most important factor attracting tourists to Jeju National Museum. The study results hold useful implications for museum managers and researchers interested in studying how demographic characteristics impact visitors' motivations and satisfactions.

The influence of self-efficacy on recovery of spontaneous arm use in hemiparetic stroke

Chen, Shu-Ya University of Southern California 2011 해외박사(DDOD)

The overall purpose of this dissertation is to determine the influence of self-efficacy on the recovery process of spontaneous arm use in people with hemiparetic stroke. Given that post-stroke arm use is a meaningful outcome within the context of the International Classification of Functioning, Disability, and Health (ICF) model, we first identified the critical predictors of arm recovery through a systematic review in order to have a better appreciation of upper limb stroke rehabilitation techniques (Chapter 2). According to this systematic review, there was a 317% increase in the frequency of articles on predictors of arm recovery over a nearly 30-year period. Early neurophysiologic and motor-behavior measures were the best predictors at follow-up of arm-specific outcomes. However, we found far fewer studies of social-cognitive factors than of neurophysiological or motor-behavior factors in predicting arm recovery after a stroke. Further, there was no outcome measure classified at the ICF participation level. Before developing a new measure, we examined two commonly used performance-based measures of spontaneous arm use (the Actual Amount of Use Test (AAUT) and the Motor Activity Log (MAL)) with respect to an important psychometric property---the minimal detectable change (MDC) (Chapter 3). The MDC is used to determine the threshold for whether a pre-post change is due to actual change and not measurement noise from a measurement perspective. Another important finding was that significant training-induced spontaneous arm use was observed in the MAL but not in the AAUT when comparing their MDC values. This discrepancy was the case both immediately after the intervention and at 1-year follow-up. This may be influenced by the nature of the instruments. Specifically, the AAUT has scoring systems with low sensitivity. In Chapter 4, fifteen participants with hemiparetic stroke and ten non-disabled adults were recruited. All participants were asked to complete the self-efficacy measure. Reaching is a task used to evaluate the participants' self-efficacy, they needed to consider which target to reach for and which hand to reach with, forming a hand-target combination. Then, participants were asked to compare two hand-target combinations and identify which combination they had higher confidence in reaching, but without actually moving their arm. In the stroke group, we found significant correlations between self-efficacy and target distance (r=-0.603, p<0.001) and self-efficacy and target location effects (r=-0.378, p<0.001). In addition, participants with stroke rated their self-efficacy to be lower when they had to reach with the paretic hand when compared to the non-paretic hand (p<0.001). The results support the validation of the self-efficacy measure for those with hemiparetic stroke. The same population was recruited to test the relationship of self-efficacy and arm selection after hemiparetic stroke (Chapter 5). All participants completed the self-efficacy measure (Chapter 4) and the arm reaching test. We found that hand-specific self-efficacy was significantly correlated with the probability of paretic hand selection for the stroke group (r=0.767; p<0.001), but not the non-dominant hand for the control group (r=0.055; p=0.88). More importantly, self-efficacy alone explained 84.2% of the variance in hand selection. The strong relationship between hand-specific self-efficacy and paretic hand selection supports the contention that perceived confidence in task-specific motor capability likely plays an important role in determining hand use after hemiparetic stroke. Given the identification of a strong relationship between self-efficacy and arm selection in the stroke group, we further examined how changes in self-efficacy would influence paretic limb choice in people with hemiparetic stroke (Chapter 6). An additional sample (n=8) was recruited and randomly assigned to two groups: self-efficacy manipulation (SE) group (n=4) and stroke-related information (SI) group (n=4). We found that the pre-morbid hand dominance may act as confounders to this result. In addition, the effective dosage and proper timing of the self-efficacy manipulation will need further investigations with a larger sample. (Abstract shortened by UMI.).

A causal model: Factors influencing pelvic muscle exercise adherence among Taiwanese women with urinary incontinence

Chen, Shu-Yueh University of Washington 2001 해외박사(DDOD)

The purposes of this study were twofold. This study was primarily designed to test the theoretical model proposing that pelvic muscle exercise (PME) adherence could be predicted by five key concepts: knowledge of PME, attitudes towards PME, partner cohesion, perceived PME benefits, and PME self-efficacy. The PME adherence studied was adherence behavior and perceived adherence. Secondarily, this study was designed to explore Taiwanese women's experiences of performing PME for urinary incontinence (UI). Using a cross-sectional, correlational design, this study incorporated both quantitative causal modeling and qualitative data. A convenience sample of fifty-five Taiwanese women with UI completed the research questionnaires measuring the key concepts in the theoretical model. Multiple regression analysis and path analysis were used for quantitative data analysis. The qualitative data were collected during in-depth interviews with 8 women who were recruited from the total sample of 55 women. Content analysis was used to analyze the interview data. As predicted in the path analysis, PME self-efficacy showed a positive direct effect on both PME adherence behavior and perceived adherence to PME. Attitudes towards PME, partner cohesion, and perceived PME benefits, respectively, had an indirect effect on both adherence behavior and perceived adherence, mediated by the PME self-efficacy. Menopausal status, and knowledge of PME had a direct positive erect on PME adherence behavior along with PME self-efficacy, respectively. Age was not a significant predictor. Qualitative data revealed that some cases confirmed some paths while the other cases confirmed other paths. Content analysis showed that women's experiences in performing PME for UI involved (a) shifts in personal priorities, (b) PME procedure uncertainty, and (c) partial PME benefit attainment. The three themes were all related to perceived PME barriers. Overall, PME self-efficacy affected both PME adherence behavior and perceived adherence to PME directly and mediated the effects of attitudes towards PME, partner cohesion, and perceived PME benefits on both outcome variables. These findings suggest that clinical interventions which facilitate PME self-efficacy may improve women's adherence to PME. Finally, perceived PME barriers may also be an influential factor of PME adherence.
