It is well known that compensation satisfaction of employees is closely related to work attitude, job commitment, and employees'intentions to stay on the job. These known facts can also be applied to the professionals engaged in science & technology as well. Many studies have concluded that the Korea's losing competitiveness in the area of science & technology was mainly attributed to the distorted compensation system. In this vein, this paper identifies the potential determinants that affect the compensation satisfaction of S&T professionals, and to empirically examines the determinants influences on job commitment and intention to stay. This was done by acquiring data from S&T professionals currently being employed in firms, universities, and institutions. Consequently, for professionals engaged in science & technology, the compensation satisfaction was demonstrated to be largely influenced by job accomplishment, monetary compensation, and social compensation in order. In conclusion, to improve compensation system for S&T professionals, firstly, it is recommended to enhance job accomplishment by endowing more discretionary authority to conduct research. Secondly, the relatively lower-valued labor forces in S&T area will necessitate more economic support and compensation. Finally, the social compensation should be strengthened by not only ameliorating social status, but also improving labor liquidity and job security.

This paper provides a case for the comprehensive performance management system in Public Procurement Service. Public Procurement Service set up the BSC system at the beginning of 2006 by improving and complementing the earliest performance management system and made it possible to automatically connet the performance measurement and evaluation of the departmental and person by using CSF and KPI, which result from their mission and strategic assignments. Therefore, the public service of the adminstration is able to offer better customer service, as the private corporations do, apply the incentive and disincentive policies to the personnel and reward administration and contribute to changing the administration into an organization of competition and performance compensation. The application of the BSC system enables the strengthening of the individual evaluation system in the departmental, integration of various evaluations into one, and the establishment of a monitering system of achievement rate in the objective management in the periodic results. Such a case study of Public Procurement Service will determine the course of establishment of the BSC in other public institutions and suggest many successful methods and ideas for the performance management system.

강화학습은 에이전트(agent)가 주어진 환경(environment)과의 상호작용을 통해서 상태(state)를 변화시켜가며 최대의 보상(reward)을 얻을 수 있도록 최적의 행동(action)을 학습하는 기계학습법을 의미한다. 최근 알파고와 같은 게임뿐만 아니라 자율주행 자동차, 로봇 제어 등 다양한 분야에서 널리 사용되고 있다. 상수도관망 분야의 경우에도 펌프 운영, 밸브 운영, 센서 최적 위치 선정 등 여러 문제에 적용되었으나, 설계에 강화학습을 적용한 연구는 없었다. 설계의 경우, 관망의 크기가 커짐에 따라 알고리즘의 탐색 공간의 크기가 증가하여 기존의 최적화 알고리즘을 이용하는 것에는 한계가 존재한다. 따라서 본 연구는 강화학습을 이용하여 상수도관망의 구성요소와 환경요인 간의 복잡한 상호작용을 고려하는 설계 방법론을 제안한다. 모델의 에이전트를 딥 강화학습(Deep Reinforcement Learning)으로 구성하여, 상태 및 행동 공간이 커 발생하는 고차원성 문제를 해결하였다. 또한, 해당 모델의 상태 및 보상으로 절점에서의 압력 및 수요량과 설계비용을 고려하여 적절한 수량과 수압의 용수 공급이 가능한 경제적인 관망을 설계하도록 하였다. 모델의 행동은 실제로 공학자가 설계하듯이 절점마다 하나씩 차례대로 다른 절점과의 연결 여부를 결정하는 것으로, 이를 통해 관망의 레이아웃(layout)과 관경을 결정한다. 본 연구에서 제안한 방법론을 규모가 큰 그리드 네트워크에 적용하여 모델을 검증하였으며, 고려해야 할 변수의 개수가 많음에도 불구하고 목적에 부합하는 관망을 설계할 수 있었다. 모델 학습과정 동안 에피소드의 평균 길이와 보상의 크기 등의 변화를 비교하여, 제안한 모델의 학습 능력을 평가 및 보완하였다. 향후 강화학습 모델을 통해 신뢰성(reliability) 또는 탄력성(resilience)과 같은 시스템의 성능까지 고려한 설계가 가능할 것으로 기대한다.

고객이 서비스상의 실패에 대해 때로는 강한 부정적 반응을 보이기에 서비스를 제공하는 조직의 서비스회복능력은 고객만족을 달성하기 위해 강력하고 효율적으로 운영되어야 한다. 따라서 본 연구는 온라인상의 서비스인 ISP업체(10개의 회사)를 대상으로 온라인 서비스 상에서 고객이 서비스상의 불만을 경험할 때 기업이 고객의 불만을 회복시켜 만족으로 전환시키려는 회복속성들이 실제로 고객이 가지는 분배상의 공정성, 절차상의 공정성 및 상호작용 공정성에 어떤 영향을 미치는가를 실증적으로 검증하기 위한 것이다. 이를 위해 10개의 ISP업체를 선정하고 해당 업체에 대해 불만을 가진 고객들이 기업의 불만제거 노력에 대해 평가하도록 하였다. 가설 검증을 위해 LISREL을 이용하여 서비스의 회복속성인 보상, 신속한 반응, 무반응, 사과, 사전보상제공 등이 분배상공정성, 절차상 공정성, 상호작용 공정성에 직접적으로 미치는 효과를 파악하고 이 공정성의 요인들이 만족에 미치는 영향도 실증적으로 검증하였다. 온라인 상이라는 새로운 환경을 고려하여 기존의 모델에서 간과된 부분을 확인하기 위해 확장 모델을 제시하여 새로운 의미를 가진 경로가 존재하는지 확인하고 이 부분에서 유의적인지 않은 경로를 배제한 수정모델을 제시하였다. 기존의 연구를 바탕으로 제시된 가설은 연구모델에서 경로 계수를 추정하고 이에 대한 t값을 통해 검증하였다. 본 연구에서 제시하는 시사점으로는 고객의 서비스 실패 및 회복상황에 대한 평가의 이론적 원칙을 설명하고 관리자에게 각각의 서비스 실패와 일치하는 서비스 회복전략을 제시하여 운영상의 가이드 라인을 제시한다고 할 수 있다

This study aims to provide solutions concerned with to residential moving companies about their operational problems. In order to shed light on these problem, factor analysis and fuzzy AHP method are adopted. Selected factors are low quality of workers and equipments, weak condition of business, policy and form of a contract, and excessive competition. The results of survey show that excessive competition is the most urgent problem compared with other problems. In the twelve-measured variables, The problem of non-certificated firms, low service quality caused by excessive competition, and claims caused by lack of service instruction are chosen as the urgent matters. As a result of the analyses, the study would propose policy directions how to solve these problems. Firstly, the government should make the legal basis of operating the industry because there is too competitive in the field. Secondly, the government should regulate firms which have not a certificate because they are the cause of low service quality in the field. Thirdly, in order to improve the service quality, the study would suggest that the managers should instruct the workers of residential moving companies. Lastly, the paper would suggest that customers check the certificate of the firm allowed by the government authorities.

This paper proposes an illuminant compensation method using a camera noise analysis without segmentation in the dichromatic reflectance model. In general, pixels within highlight regions include large amounts of information on the image illuminant. Thus, the analysis of highlight regions provides a relatively easy means of determining the characteristics of an image illuminant. Currently, conventional methods require regional segmentation and the accuracy of this segmentation then affects the illuminant estimation. Therefore, the proposed method estimates the illuminant without segmentation based on a conformity assessment of highlight regions. Furthermore, error factors, such as noise and sensor non-uniformity, can be reduced by the conformity assessment.

Purpose: This study determined the relationships between maternal comprehensive feeding practices (CFP) and dietary practices of preschool children. Methods: Participants of the study were 227 mothers of children aged 3 to 5 years attending daycare centers and kindergartens in Seoul and Gyeonggi Province of Korea. The Comprehensive Feeding Practices Questionnaire was used to assess the maternal feeding practices. The Nutrition Quotient for Preschoolers (NQ-P) was measured to evaluate dietary practice and diet quality of children. Results: The balance of NQ-P for children was positively correlated with the modeling, restrictions for weight control, encouragement of balance and variety, pressure, and involvement among maternal CFP. Moderation of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement among maternal CFP. However, it was negatively correlated with emotion regulation, food as a reward, and child control in maternal CFP. Among maternal CFP, the environment of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement, and it was negatively correlated with emotion regulation. As a multiple regression analysis, maternal CFP that positively predicted balance of NQ-P indices were restricted for weight control, pressure, and involvement. Among maternal CFP, encouragement of balance and variety, and environment were positive predictors, while food as a reward, and child control were negative predictors for the moderation of NQ-P. Items of maternal CFP positively predicting environmental factors of NQ-P were monitoring and environment. Conclusion: Mothers are recommended to practice dietary guidance to their children, such as monitoring, modeling, teaching about nutritional information, recommendation of balance and diversity, healthy eating environment, and participation in meal plan and preparation, while they are advised not to conduct any adverse dietary guidance such as emotional control, compensation with food, child control, and food coercion.
