金融機關의 顧客滿足經營戰略(CSMS)開發에 관한 硏究 : H&C銀行의 事例를 중심으로

윤희남 전남대학교 경영대학원 1997 국내석사

The purpose of this study is to present the basic analysis data which help H&C bank to make the marketing policy and execution of Customer Satisfaction Management Strategy. H&C bank management has dealt with only coming customer in the situation of stable money market. But in the future bank management "the user market" must be much more important than "the supplier market" according to the changes in the financial circumstance, and so H&C bank strongly recognizes that H&C bank has to propel the management innovation and customer control based on the strategy for competitive predominance. From the viewpoint that the CSMS(Customer Satisfaction Management a Strategy) of H&C bank has a limitation to the existing market or management pointed to the customer, it is considered logically and actually resonable to establish the competitive strategy for market's predominance and to realize the strategy for customer satisfaction, based on the thought pointed to the market. The result of this study shows that the thought pointed to the customer or the CSMS is the marketing pointed to the market to manage three kinds of customers altogether. In other words, CSMS is the management activity to meet the need of three customer groups, that is, "the customer consuming value", "the customer accelerating value" and "the customer producing value", and to maximize the degree of satisfaction formed in exchange relations of three groups in them in the end. This study uses the literature on the existing academic data, various policy research and reports of practical business, conducts a SWOT analysis including the tendency analysis and considers the investigator's field experiences and related expert's advices. This study investigates the relations between marketing characteristics and Customer Satisfaction Management, general contents of Customer Satisfaction Management, and CSMS in domestic and foreign banks, referring to do currents, and then summarizes the data about the degree of satisfaction through an interview with or questionnaire by mail for a customer, which has an account with H&C bank, and suggests the strategy for fixing the policy of Customer Satisfaction Management. By the way this study doesn't make a practical program available for the customer and store management, with senses for problems in customer satisfaction. In short, when H&C bank gives customers much better services and goods than are expected, in the attitude that customer satisfaction starts here, from me, and just now, it will be estimated positively like "Satisfaction".

Analysis on the Synchronization of Electrocardiogram during Sleep

윤희남 서울대학교 대학원 2018 국내박사

Human physiological systems continuously interact for effective body functioning to contribute to physiological homeostasis. Theoretical insights into nonstationary and nonlinear dynamics have been employed to identify the physiological interaction, and have yielded various interaction characteristics. However, the physiological dynamics revealing high degree of complexity transiently change their characteristics in different states and conditions under their own regulatory mechanisms. Thus, understanding the physiological interaction is still challenging. This thesis proposes methods to identify and quantify the interactions of inter- and intra-personal physiological systems during sleep, focusing on the cardiac system. As for the interaction between intra-personal physiological systems, directional coupling in the cardiorespiratory system was evaluated in different physiological states (sleep stages) and conditions, i.e., severity of obstructive sleep apnea (OSA). Directionality analysis was performed with heartbeats acquired from electrocardiogram and abdominal respiratory effort measured from the polysomnographic data of 107 healthy individuals and patients with OSA. Unidirectional coupling from the respiratory system to the cardiac system increases during wakefulness and rapid eye movement sleep, and significantly decreases during light and deep sleep, which is further decreased in deep sleep, approaching bidirectional coupling. In addition, unidirectional coupling from the respiratory system to the cardiac system also significantly increases according to the severity of OSA. The stratification pattern found in both sleep stages and OSA severity is statistically significant (all pairwise multiple comparisons in sleep stages and OSA severity by Tukey’s test, p < 0.05). The influence from the respiratory system to the cardiac system gradually decreases from wakefulness and REM sleep to light and deep sleep, and the influence from the cardiac system to the respiratory system is the highest in deep sleep and gradually decreases to wakefulness via light and REM sleep (Tukey’s test, p < 0.05). The similar stratification pattern is also observed according to OSA severity (Tukey’s test, p < 0.05). The directionality index maintained higher values within the heart and respiratory rates in particular ratios, implying that the increment of directionality index approaching bidirectional coupling is determined by the changes in and/or influence of both systems. Age-dependent characteristics of the directional coupling of the cardiorespiratory system are also found, i.e., the elderly group (age ≥ 50) reveals significantly higher unidirectional coupling from the respiratory system to the cardiac system compared to that in the young group, maintaining a sleep stage-dependent stratification pattern of the cardiorespiratory coupling (independent samples t-test, p < 0.001). These coupling characteristics in different states and conditions are believed to be linked with autonomic nervous modulation. A possibility of coupling between inter-personal physiological systems was investigated for heart rhythms of co-sleeping individuals under an environment where they were in contact with each other. The interaction characteristics were approached with two different aspects, namely, inter-personal heart rhythmic phase synchronization (IHPS) and inter-personal heart rhythmic causal relation (IHCR). Experimental evidence was found that independent heart rhythms appeared in the same relative phase for prolonged periods (IHPS) and their occurrences had bidirectional causal relation (IHCR) in co-sleeping individuals. The degree of IHPS was at least two times higher in co-sleeping individuals than in separately sleeping individuals (Wilcoxon signed-rank test, p < 0.03). IHCR also showed significant increase in both directions of heart rhythms in co-sleeping condition (Wilcoxon signed-rank test, p < 0.03). In addition, IHPS was characterized by an increase of IHCR in both directions compared with those in non-IHPS (independent samples t-test, p < 0.001), indicating that IHPS was determined by fine tuning of rhythmic phases under bidirectional interaction, not by one-way influence from one to another. The standard deviation of R-R intervals in IHPS was significantly lower than that in non-IHPS for co-sleeping individuals (independent samples t-test, p < 0.001), indicating that the phase coupling of heart rhythms in co-sleeping individuals was associated with decreased sympathetic and increased parasympathetic activities. Therefore, this finding implies that IHPS was associated with the regulation of the autonomic nervous system. Under controlled experimental conditions, the finding could be attributed to weak cardiac vibration delivered by one another through bed connection. The approaches in this thesis are useful in understanding how the systemic interaction contributes to efficient body functioning for maintaining physiological homeostasis under internal and external environmental changes. In addition, it is expected that the proposed analytics can provide objective evidence of how one systemic abnormality causes other systemic dysfunctions and/or disorders based on the physiological interaction aspect. The findings imply that intrinsic physiological rhythms can be modulated by the rhythm of an independent external system. Therefore, the research can be extended to identify whether physiological rhythms can be adjusted by an external device, whose frequency and phase can be controlled. Further it can lead to physiological systems in a positive manner. In addition, the approaches are expected to elucidate how sharing behavior or social relationship of individuals is associated with physiological systemic interaction.
