Modern financial services go beyond the stage of internet banking, and new concepts of financial transactions such as Internet of Things, mobile banking, electronic payments, and fintech have emerged. As a result, banks are less influential in financial transactions, and changes are being demanded. In the present era, the basic business of banks has decreased, and it is transforming into a space where both consumer finance work and reside. The bank office stands for the brand image of the bank, and it is represented by trust with customers in the basic business of financial transactions, and the rise in real estate value is a natural social phenomenon due to the nature of the location and location of real estate owned by the bank. The business method and space of the bank office that meets the new paradigm of the modern society is an inefficient space only for the convenience and rest of consumers, but it must be used as a variety of spaces suitable for the region to increase the functional value of the bank office. Through this study, as a convenience space for consumers, various service facilities should be introduced to understand the characteristics of the region as a convenience space for consumers, and various service facilities should be introduced to meet the needs of consumers, and the bank office should be improved as a complex service space for local residents.

It rains heavily, such as long rain and typhoons, during a typical rainy season in Korea. In this season, several fuel contamination accidents by water and vehicular problems caused by water contaminated fuel occur. Many research groups have studied the effects of water contaminated fuel on vehicles and environment. However the characteristics of water contaminated fuel have not been studied. In this study, we prepared diesel samples with a constant ratio of water (0~30 volume %) using an emulsifier. Then, we analyzed these diesel samples for their representative fuel properties. In the analytical results, diesel with 30% water showed an increase in fuel properties such as density (823→883 kg/㎥), kinematic viscosity (2.601→6.345 ㎟/s), flash point (47→56℃), pour point (-22→2℃), CFPP (cold filter plugging point) (-17→20℃) and copper corrosion number (1a→2a). The low temperature characteristics, such as low pour point and CFPP, blocks the fuel filter in the cold season. In addition, water contaminated diesel decreases lubricity (190→410 ㎛) under high frequency reciprocating rig (HFRR) and derived cetane number (54.81→34.25). The low lubricity of fuel causes vehicle problem such as pump and injector damage owing to severe friction. In addition, the low cetane diesel fuel increases exhaust gases such as NOx and particulate matters (PM) owing to incomplete combustion. This study can be used to identify the problems caused by water contamination to vehicle and fuel facilities.

이 연구의 목적은 원격근무 환경에서 조직구성원의 업무수행에 있어 긍정적인 영향과 부정적인 영향을 미친 상사의 리더십 행동 및 원격근무 시 기대되는 상사의 역량을 구명하는데 있다. 이를 위해 경력 1년 이상의 19명 사무직 종사자를 대상으로 중요사건기술법(CIT)을 활용하여 인터뷰를 실시, 분석하였다. 이 연구의 결과는 다음과 같다. 첫째, 원격근무 시 조직구성원의 업무수행에 긍정적인 영향을 미치는 상사의 리더십 행동은 10개의 행동특성으로 분석되었고 관계중심적 행동, 과업중심적 행동, 변화중심적 행동 순으로 언급빈도수가 높았다. 둘째, 원격근무 시 조직구성원의 업무수행에 부정적인 영향을 미치는 상사의 리더십 행동은 9개의 행동특성으로 분석되었고 관계중심적 행동, 과업중심적 행동, 변화중심적 행동 순으로 언급빈도수가 높았다. 셋째, 원격근무 시 상사에게 기대되는 역량은 13가지로 분류하였다. 이를 바탕으로 결론을 도출하고 후속 연구를 위한 제언을 하였다.

The purpose of this study is to propose indoor noise level in residential buildings affected by transportation noise (road traffic, railway and air-craft noise) based on subjective evaluations. 30 subjects participated in the experiment to evaluate the noise. Experimental environment reproduced real living and office environment, and in asking subjects' annoyance to the noise. (omitted)

To understand runoff Phenomena in Jeju island, some streams are monitored automatically about stream stage, and water quality in Jeju Provincial Water Resources Management Office. Rating curves for stream discharge are reviewed. Stream stages respond very quick to some rainfall events, and parameters influencing runoff phenomena such as landuse, soil condition, preconditoned rainfall, and vegetables will be studied. A few thousand to ten thousand ml/day are estimated from 6 permanent streams in Jeju island.

Even if there are lots of researches on localization using 2D range finder in static environment, very few researches have been reported for robust real-time localization of mobile robot in uncertain and dynamic environment. In this paper, we present a new localization method based on ICP(Iterative Closest Point) algorithm for navigation of mobile robot under dynamic or uncertain environment. The ICP method is widely used for geometric alignment of three-dimensional models when an initial estimate of the relative pose is known. We use the method to align global map with 2D scanned data from range finder. The proposed algorithm accelerates the processing time by uniformly sampling the line fitted data from world map of mobile robot. A data filtering method is also used for threshold of occluded data from the range finder sensor. The effectiveness of the proposed method has been demonstrated through computer simulation and experiment in an office environment.
