This paper explores the influence of pursuing goals on customer channel preference in Chinese rural market. With the rapid change in distribution channels and increase in multi-channels, it is necessary to understand the preference for channel choice as well as product choice. This study empirically validated the conceptual framework of the relationship between the pursuing goals and customer channel choice proposed by Balasubramanian, Raghunathan, and Mahajan (2005). Based on the survey data of 232 fertilizer customers in Chinese rural market, this study explores how economic, social, and psychological pursuing goals can impact customer channel preference by mediating variables of product utility and process utility. The results indicate that pursuing goals positively related with product utility and process utility, and product / process utility can mediate the relationship between pursuing goals and customer channel preference positively. Consequently, we can conclude that customers' economic-social-psychological pursuing goals can directly influence customer channel preference via their purchase process utility and product utility. This result also implies that product utility is effective on process utility during consumer's buying decision making, and process utility and product utility are not mutually independent. Therefore, purchase process utility is a "latent driving force" on customer's channel choice decision.

The ever-growing demand for enhanced competitiveness of engineered systems require designing in quality strategies that can efficiently incorporate multiple design attributes into a system. In a robust design, there must be consideration for any uncontrollable factors that should not be disregarded in the design process. Studies on multi-attribute design challenges usually assume mutual utility independence amongst the design attributes. However, mutual utility independence does not exist in every design situation. In this study, a new robust design methodology that has two utility-dependent attributes are presented. The proposed method was then compared with a traditional robust design that utilizes a wave soldering process design. The results of this case study indicate that the proposed method yields a better solution than the traditional method.

Purpose: In terms of the flexibility in hospital architecture, there are fixed elements of hospital architecture: mechanical, electrical, aeration rooms and shafts, which are the main utility spaces. Thus, it is necessary to recognize the utility space as a system that helps internal functions and flexible internal changes. This study analyzes the notion of the main utility space in hospital architecture and the architectural planning features of the main utility spaces as the system in the design process of the recently built hospitals. Methods: The design factors are extracted comparing two hospitals' plans in each stage and the systematic characteristics of utility spaces are analyzed accordingly. The opinions gathered from interviews of practitioners, architects and facility planning experts directly involved in the architecture design process are analyzed and reflected in the results. Results: Planning for utility spaces should be accompanied by the architectural plan from the basic design process, and proceeded with recognizing utility spaces as a system, which is a fixed element. Utility spaces are highly organically connected. Horizontal and vertical distribution of air chambers can reduce the length and number of ducts, and thus save story height, and reduce the number of shafts, the vertical connection passage. This is advantageous in securing the variable area, which is the ultimate objective of the system-centered hospital architecture plan. Implications: Thereby aims to provide fundamental data on systematic utility space planning in the hospital architecture planning.

This study was performed to make suggestions for improving consumer welfare in public utility pricing. The consumer related issues in the process of public utility pricing and the consumers' burden on expenditures for public utility were reviewed. Due to the large proportions of the expenditures for public utility to total consumption expenditures, the poor and the younger consumers had more disadvantages in rising consumer price on public utility than the rich and the older. Finally, four kinds of alternatives were suggested to solve the consumer problems in public utility pricing.

Wrinkle and fracture are two major defects frequently found in the sheet metal forming process. In this process there are more than one design attributes to optimize and several uncontrollable factors which cannot be ignored in determining the optimal values of design variables. Therefore, attempts to reduce defects through a traditional optimization technique are often led to failures. In this research, a new design method for reducing the wrinkle and fracture under uncontrollable factors is presented by using decision-making theory. To avoid the psychological difficulties in determining the scaling constants of the multi-attribute utility function by using the ordinary lottery questions, a pair-wise comparison procedure is adapted to avoid this problem. The effectiveness of the proposed method is illustrated through a robust design of sheet metal forming process of a side member of an automotive body.

Purpose - Drawing on the content-process approach, this study examines the effect of employees' perceived utility of education and training in small and medium enterprises (SMEs) on their satisfaction. In addition, this study investigates how the human resource management department' activities moderate the relationship between employees' perceived utility of education and training and satisfaction. Design/methodology/approach - This study predicts the positive relationship between employees' perceived utility of education and training and satisfaction, and HR activities strengthens this positive relationship. To test these hypotheses, this study utilized Human Capital Corporate Panel (HCCP) datasets, especially 2017 data at the individual level. The number of the final sample is 425 for the test. Moreover, this study used the hierarchical regression model with SPSS. Finding - As predicted, the analytical results with the hierarchical regression model showed that employees' percieved utility of education and training and satisfaction were positively related. In addition, HR activities strengthened this relationship between employees' percieved utility of education and training and satisfaction. Research implications or Originality - This study will provide academic and practical implications for future research on human resource development, especially SMEs by deepening an understanding of the important factors in order to increase employees' satisfaction of education and training. the number of viewers is found in most American films released in Korea.

ABS 중합공정 중 잔류 모노머 회수 공정의 유틸리티 사용량 절감을 위한 공정의 개선을 수행하였다. ABS 폴리머 생산 과정 중 잔류 모노머 회수 공정은 제품의 품질 향상을 위해 반드시 필요하다. 잔류 모노머의 회수를 위한 다양한 방식이 있으나, 본 연구에서 대상으로 한 것은 스팀 스트리핑 공정이다. 기존의 스팀 스트리핑은 많은 양의 스팀과 냉각수가 사용되고 있으나, 본 연구를 통해 유틸리티 사용을 절감하는 새로운 방안을 찾고자 하였다. 스트리핑 후 모노머와 함께 배출되는 스팀의 잠열을 진공상태의 수증기로 회수하고, 압축으로 온도를 상승시켜 스트리핑 스팀으로 재사용하도록 함으로써 스팀의 사용을 획기적으로 절감하였다. 또한 모노머 최종 회수 과정에서 발생되는 물을 모노머 응축에 냉각수로 활용함으로써 용수에 대한 사용량도 감소 시킬 수 있었다.

대부분의 화학공장에서는 유틸리티의 운용에 따라 경제성이 크게 좌우된다. 공장에서 이용되는 유틸리티는 중앙 집중화된 유틸리티 시스템에 의해 제공되는데 유틸리티 가운데 가장 큰 비중을 차지하는 것은 수증기로서 이의 효율적인 관리는 공장의 전력 및 용수의 수급에도 직접적인 영향을 미치게 된다. 이에 따라 대학교 4학년 학생 및 회사의 신입사원들이 유틸리티의 효율적 분배에 대한 개념을 바르고 신속하게 정립하고 실제 운전에 활용할 수 있도록 하는 것이 중요하다. OOUS(optimal operation of utility system)는 빠른 시간 내에 유틸리티, 특히 수증기의 효율적 생산과 최적 배분방법들을 학생들이나 신입사원들에게 교육시킬 수 있도록 구성된 시스템이다. OOUS에서는 다양한 유틸리티 관련장치 및 공정들을 다루고 있으며 유틸리티 관련 장치 모델과 운전지식 베이스를 기반으로 최적 운전조건이 제시되도록 함으로써 전체 유틸리티 플랜트의 조업 경비가 절감될 수 있도록 하였다.
