본 연구는 금융시장의 환경변화에 따라 어려움을 겪고 있는 지역농협이, 농협 금융서비스에 대한 고객의 욕구를 파악하고 추후 고객지향의 다양한 전략구사나 서비스를 개선하는데 도움이 될 목적으로 이루어지게 되었다. 연구는 이론고찰과 실증분석을 통해 이루어졌다. 먼저 "서비스"와 "서비스 품질"에 대한 이론적 고찰을 통해 본 연구의 모형을 도출하였다. 연구모형에서 제시한 연구내용을 분석하기 위해 농협 금융서비스를 이용하는 고객을 대상으로 설문조사를 실시하였다. 설문결과를 분석하기 위해 SPSS Win 10을 이용하여 빈도분석, 요인분석, t-test, 회귀분석, 교차분석을 실시하였다. 분석 결과, 지역농협의 금융 서비스 품질결정요인으로 신뢰성, 공감성, 유형성, 편의성이라는 요인이 추출되었고, 이들 요인에 대한 기대서비스와 지각서비스에 차이가 있는 가에 대한 분석 결과 차이가 있는 것으로 나타났다. 특히 모든 요인에 대한 변수의 (지각수준 - 기대수준) 값이 마이너스로 나타나 기대수준 보다 지각수준이 낮음을 알 수 있다. 또한 서비스 품질 결정요인들이 고객만족에 영향을 미치는가에 대한 분석 결과, 편의성을 제외한 신뢰성, 공감성, 유형성 요인들이 고객만족에 영향을 미치는 것으로 분석되었다. 고객만족에 영향을 미치는 요인 중 특히 공감성, 유형성, 신뢰성 순으로 회귀계수의 크기가 나타나 공감성이 고객만족에 가장 큰 영향을 미치는 것으로 나타났다. 서비스 품질 결정요인들이 재구매에 영향을 미치는가를 알아본 결과 신뢰성, 공감성, 유형성, 편의성 요인 모두 재 구매에 영향을 미치는 것으로 분석되었다. 4개 요인 중 공감성의 회귀계수가 가장 크게 나타났고 이어 신뢰성, 편의성, 유형성의 순으로 나타나 재구매에도 공감성 요인이 가장 큰 영향을 미치는 것으로 분석되었다. 마지막으로 지역농협 금융 서비스에 대한 고객의 만족/불만족과 재구매와의 관계를 분석했는데 두 변수사이에 유의한 관계가 있는 것으로 분석되었다.

The inspection policy and inspection error are very critical factors which influence the outgoing quality. In other words, such factors influence the acceptance rate of the incoming matarials. Hence, the outgoing lot size is varied. This paper presents a method to compute the break-even point(pb1, pb2) under these two factors, which canbe used to determine the economic acceptance inspection type.

As recently raw water quality has been polluted as well as its quality has been remarkably varied according to season and region, the precise control of coagulant dosage is being keenly required in water treatment plants. The amount of coagulant is closely related to raw water quality such as turbidity, alkalinity, water temperature, pH, electrical conductivity, etc. Since the optimum quantity of chemicals is not yet finalized, so dosage rate must be decided by using jar test that takes one or two hours. Hereupon, the output signal of stream current and multi-regression on historical data were proposed to be applied to the coagulant dosing control. In consequence of applying the scheme to automatic determination of the dosage rate, it was testified that the determination of dosage rate was very effective in case it is performed as to real-time sensing of water quality and the output signal of stream current.

분말고추가루에 씨앗이나 꼭지를 혼입시켜 저장시킨 결과 capsanthin, capsaicin, total-sugars 등의 성분이 감소되었으며 특히 꼭지가 혼입된 시료보다 씨앗이 혼입된 시료에 있어서 품질의 열화정도가 큼을 알 수 있었다. 이와 관련하여 씨앗이나 꼭지의 함량을 근적외 분광분석법으로 측정할 수 있는지의 가능성을 조사한 결과 씨앗의 혼입량은 1.76%의 측정오차로, 꼭지의 혼입량은 0.43%의 측정오차로 각각 30초 이내에 통시 측정할 수 있음을 확인하였다.

The simultaneous determination of platyphylloside, aceroside and betulin was established for the quality control of Betula platyphylla bark using a high performance liquid chromatography and diode-array UV/Vis detector (HPLC-DAD). Separation and quantification were successfully achieved with a INNO C18 column ($5{\mu}m$, 4.6 mm $I.D.{\times}150mm$) by gradient elution of a mixture of methanol and water at a flow rate of 1.0 ml/min. Validation of the developed method was performed by various factor such as linearity, specificity, precision, accuracy, system suitability and stability. This method was successfully applied to the determination of contents of platyphylloside, aceroside VIII and betulin in three batches of Betula platyphylla bark extract. These results suggest that the developed HPLC method is simple, effective and could be utilized as a quality control method for Betula platyphylla bark products.

A fast and simple high-performance liquid chromatography (HPLC) method for the simultaneous determination of four pesticides having fungicide properties has been proposed for Panax ginseng, C. A. Meyer grown for 4, 5, or 6 years. Analytical separation was performed on C18 columns using ultraviolet detector under gradient conditions. Spiked blank samples were used as standards to counteract the matrix effect observed in the chromatographic determination. The HPLC response for all pesticides was linear, with determination coefficients > 0.9986. The average rate of recovery for pesticides spiked with 2 fortification levels was > 72% with relative standard deviations < 9%. The limits of quantification (LOQ) ranged from 0.03 to 0.16 ppm. These LOQs were lower than the respective maximum residue limits (MRL) established by the Korean Food and Drug Administration (KFDA), except for cyazofamid. The proposed method was used to determine pesticide residue levels in samples of ginseng obtained from Jeonnam Province (Republic of Korea). None of the pesticides were found in ginseng samples grown for 4, 5, or 6 years.

In this study, we present the results of orbit determination (OD) using satellite laser ranging (SLR) data for the Science and Technology Satellite (STSAT)-2C by a short-arc analysis. For SLR data processing, the NASA/GSFC GEODYN II software with one year (2013/04 - 2014/04) of normal point observations is used. As there is only an extremely small quantity of SLR observations of STSAT-2C and they are sparsely distribution, the selection of the arc length and the estimation intervals for the atmospheric drag coefficients and the empirical acceleration parameters was made on an arc-to-arc basis. For orbit quality assessment, the post-fit residuals of each short-arc and orbit overlaps of arcs are investigated. The OD results show that the weighted root mean square post-fit residuals of short-arcs are less than 1 cm, and the average 1-day orbit overlaps are superior to 50/600/900 m for the radial/cross-track/along-track components. These results demonstrate that OD for STSAT-2C was successfully achieved with cm-level range precision. However its orbit quality did not reach the same level due to the availability of few and sparse measurement conditions. From a mission analysis viewpoint, obtaining the results of OD for STSAT-2C is significant for generating enhanced orbit predictions for more frequent tracking.

With the development of information and communication technology, logistics distribution systems and services have been improved, new types of services have been provided, and consumption patterns in consumer markets have also changed. In the domestic distribution market, the development of ICT technology, the spread of smart devices, and the growth of the e-commerce market have led to Omni-channel, a service that integrates offline channels and online channels. Omni-channel service aims to provide consumers with consistent and convenient service by integrating offline and online domain into one. Consumers can get integrated service on and offline. In this study, consumers' intention to use Omni-channel was examined by Self Determination Theory and SERVQUAL. The survey was conducted on Omni-channel user and the research model was composed of 2^nd order factor model considering the characteristics of Omni-channel which provides integrated service based on the prior literature and PLS-SEM (partial least squares structural equation modeling).

In order to determine the level of service which minimizes the total of expected cost of service and the expected cost of waiting for that service, the important considerations are to evaluate the distance traveled to and from a service facility (D) and the expected number of mechanics in queueing system (L). The travel-time models are very useful when the servers must travel to the customer from the service facility. Thus, in this paper we studied on the determination of the optimal service level by the travel-time models. In order to decide the optimal service level, (D) has been introduced as a uniform distribution and (L) has been introduced as M/M/S model of queueing theory.
