The main objective of this study was to investigate the customer's satisfaction level with the digital relationship model of Banco do Brasil Exclusive Business Offices situated in Rio Grande do Sul. Banco do Brasil is one of the largest Brazilian and global financial institutions and conducted a restructuring customer's relationship model since 2015, creating new specific service structures for certain segments, among them exclusive offices. This research had a qualitative step with an internal documentary analysis about the company and a semi-structured interview with manager's offices, in order to check the strategy and the foundations of business model, as well as identify perceptions and the difficulties in implementing this new structure. The quantitative step held the findings about customer satisfaction level in relation to the quality of services provided by offices, through an electronic survey based on the Servqual Scale developed by Parasuraman et al. (1988), which measures the difference between customer's expectations and perception in five dimensions: tangibility, reliability, understanding, safety and empathy. The results shown that Banco do Brasil customers' are satisfied with services offered through the digital model and the new business structure, in which is offered a humanized service together with the best technology. It was found, also, that digital probably would not replace the physical world, but they complement one another. Digital offices and physical agencies will coexist, improving value proposition delivery and better customers experience, satisfy them and build their loyalty.

To achieve a cooperative work between human and robot, it is thought helpful to estimate the states of human mind, which originates his behavior. In this paper, human mind was considered to modify instinctive desires according to the conditions of external world surrounding the instinct. A simple human mind model was designed so that it finds a balance between instinctive desire and restriction from the external world. The external world is divided into three sub-worlds like subject´s whole body, its partner and concerned periphery. Proposed mind model has three-layers construction. Each of the layer tries to find a balance between desire and restriction from external world. In each layer, the role of finding the balance was expressed by an identical optimal control minimizing a performance index function of quadratic form with a weight factor, which is rearranged and named ...

The accurate forecasting of insurance claims is a critical component for insurers' risk management decisions. Hierarchical Bayesian parametric (BP) models can be used for health insurance claims forecasting, but they are unsatisfactory to describe the claims distribution. Therefore, Bayesian nonparametric (BNP) models can be a more suitable alternative to deal with the complex characteristics of the health insurance claims distribution, including heavy tails, skewness, and multimodality. In this study, we apply both a BP model and a BNP model to predict group health claims using simulated and real-world data for a private life insurer in Indonesia. The findings show that the BNP model outperforms the BP model in terms of claims prediction accuracy. Furthermore, our analysis highlights the flexibility and robustness of BNP models in handling diverse data structures in health insurance claims.

Harmonized World Soil Database (HWSD) including the global soil information has been implemented to the runoff analysis in many watersheds of the world. However, its accuracy can be a critical issue in the modeling because of the limitation the low resolution reflecting the physical properties of soil in a watershed. Accordingly, this study attempted to assess the effect of HWSD in modeling by comparing parameters of the rainfall-runoff model using HWSD with the detailed soil map. For this, Grid based Rainfall-runoff Model (GRM) was employed in the Hyangseok watershed. The results showed that both of two soil maps in the rainfall-runoff model are able to well capture the observed runoff. However, compared with the detailed soil map, HWSD produced more uncertainty in the GRM parameters related to soil depth and hydraulic conductivity during the calibrations than the detailed soil map. Therefore, the uncertainty from the limited information on soil texture in HWSD should be considered for better calibration of a rainfall-runoff model.

본 논문에서는 기존에 사용한 물리적 카메라 모델 대신 퍼지 모델을 사용한 새로운 카메라 보정 방식을 제안한다. 카메라 보정은 카메라의 영상 좌표계와 실제 환경이 가지는 좌표계와의 관계를 규정하는 것으로, 퍼지 모델을 이용하는 방법은 기존의 방법에서 이용했던 물리적 변수들을 설정할 수는 없지만 카메라 보정의 목적인 카메라 좌표계와 실제 환경 좌표계와의 관계를 별다른 제약없이 규정할 수 있으므로 매우 간단하고 효율적인 카메라 보정 방법이다. 실제 실험을 통해 얻은 실공간상의 하나의 보정면 좌표에 대해 퍼지 모델링 방법을 이용하여 3차원 실 공간 좌표 및 2차원 영상좌표 예측을 통해 제안한 방법의 유효성을 보인다.

본 연구에서는 소셜 네트워크를 생성 할 수 있는 인공적인 네트워크 발생 모델을 제안 하였다. 본 연구에서 제안한 발생 모델은 온라인 소셜 네트워크의 특징인 Small-World 성질과 Scale-Free 성질을 단순하게 표현하는 것에서 벗어나 모델의 두 파라메터를 적절히 조절함으로서 사용자가 원하는 다양한 위상 특성치 값들을 나타내 줄 수 있도록 하였다. 이를 위해 Preferential Attachment의 세기를 조정 할 수 있도록 파라메터 K와 군집화 계수를 적절하게 조정 할 수 있도록 파라메터 P를 도입하였다. K가 0에서 10 그리고 P가 0.3에서 0.5 사이의 조합이나 K = 0과 P = 0.9를 이용하면 소셜 네트워크의 위상적 성질을 보유하는 인공적인 네트워크를 생성할 수 있다. 이 조합 하에서는 Small-World 성질과 Scale-Free 성질이 잘 나타난다. 노드차수 분포는 Power-Law를 따른다. 또한 군집화 계수 0.130 ~ 0.238, 평균 최단거리 5.641 ~ 5.985로 나타났다. 또한 네트워크의 크기를 노드 5,000개에서 10,000개로 증가시켜도 소셜 네트워크 성질을 그대로 유지하는 것으로 나타났다.

Background: The International Commission on Radiological Protection is preparing to provide reference dose coefficients for environmental radioiodine intake based on newly developed age-specific biokinetic models. However, the biokinetics of iodine has been reported to be strongly dependent on the dietary intake of stable iodine; for example, the thyroidal uptake of iodine may be substantially lower in iodine-rich regions than in iodine-deficient regions. Therefore, this study attempted to establish a system of age-specific thyroid dose estimation for South Koreans, whose daily iodine intakes are significantly higher than that of the world population. Materials and Methods: Korean age-specific biokinetic parameters and thyroid masses were derived based on the previously developed Korean adult model and the Korean anatomical reference data for adults, respectively. This study complied with the principles used in the development of age-specific biokinetic models for world population and used the ratios of baseline values for each age group relative to the value for adults to derive age-specific values. Results and Discussion: Biokinetic model predictions based on the Korean age-specific parameters showed significant differences in iodine behaviors in the body compared to those predicted using the model for the world population. In particular, the Korean age-specific thyroid dose coefficients for ¹²⁹I and ¹³¹I were considerably lower than those calculated for the world population (25%-76% of the values for the world population). Conclusion: These differences stress the need for Korean-specific internal dose assessments for infants and children, which can be achieved by using the data calculated in this study.
