복잡성(complexity)은 신제품개발 과정에서 프로젝트 팀이 빈번하게 당면하는 개발과제의 주요 속성으로 이에 대한 적절한 대처 여부는 신제품개발의 성과에 적지 않은 영향을 미친다. 복잡성이란 속성이 신제품개발의 관리에서 주목 받게 된 배경으로는, 우선 제품개발과정에서 당면하는 복잡성이 증가 추세에 있다는 점을 들 수 있다. 새로운 기술과 공법 그리고 소재의 등장, 복합 제품의 개발(예: 디지털 컨버전스), 또한 기업간 제휴를 통한 개발은 신제품개발의 복잡성 증대와 관련이 된다. 한편 신제품개발의 복잡성에 대한 미흡한 대처는 개발과정의 지연, 개발비용의 예산 초과, 제품개발의 포기 등과 같은 부정적 결과를 초래한다. 이와 같이 복잡성의 증대 추세 및 복잡성으로 인한 적지 않은 영향력을 고려해볼 때, 신제품개발 과정에서 당면하는 복잡성에 대한 연구의 필요성은 증대된다. 그러나 아직까지 복잡성에 대한 연구는 현실적 필요성에 비해 상대적으로 적은 관심만이 기울여져 왔다. 본 고에서는 신제품개발 과정에서 당면하는 복잡성에 대한 주요 연구과제들을 살펴보는데 그 목적이 있다. 이를 위해 우선, 주요 영역별로 나누어 그간의 복잡성에 대한 연구성과를 정리한 다음, 이를 토대로 향후 중요시되는 연구과제들을 도출하고자 한다. 신제품개발 과정의 복잡성에 대한 주요연구과제에 대한 이러한 고찰은, 향후 이 분야에 대한 연구 전개에 있어서 하나의 발판이 될 것으로 기대된다.
공공기관들의 지방이전은 '국가균형발전'을 위해 시행된 정책으로 2019년에 한국과학기술기획평가원의 충북혁신도시 이전을 끝으로 마무리되었다. 전력공기업 또한 전국 8개 지역으로 이전을 완료하였는데, 본 연구에서는 지방이전이라는 조직변화에 따른 심리적, 경제적, 생활환경 등 다양한 측면에서의 변화와 그 영향을 실증적으로 분석하였다. 세부적으로는 이들 기관 구성원들의 조직변화에 따른 심리상태를 바탕으로 공공봉사동기와 직무태도 간의 구조관계를 파악하여, 전력공기업의 지방이전 이후의 안정화 방안을 모색하는 한편, 2차 공공기관 지방 이전에 의한 '국가균형발전'에 기여할 수 있는 시사점을 제시하고자 한다. 이번 연구에서 지방이전에 따른 심리상태와 조직몰입과는 통계적으로 유의한 관계가 있고, 기대심리가 높을수록 조직몰입이 높아지는 관계를 보인 반면, 불안심리는 조직몰입과 관계가 없는 것으로 분석되었다. 기대심리와 이직의도는 유의적이지 않았으나, 불안심리가 강할수록 이직의도가 높아지는 것으로 나타났다. 또한 기대심리가 높을수록 공공봉사동기도 증가하며, 불안심리가 높을수록 공공봉사동기는 낮아지는 것으로 분석되었다. 그리고 공공봉사동기가 클수록 조직몰입 또한 커지지만, 이직의도와는 유의적이지 않는 것으로 나타났다. 조직변화로 인한 기대심리와 이직의도 간 공공봉사동기의 조절효과는 유의적이지 않았으나, 그 이외 불안심리는 공공봉사동기의 조절효과가 유의적인 관계를 형성하는 것으로 분석되었다. 특히 조직변화에 대한 기대심리가 공공봉사동기에 미치는 영향은 전력공기업 구성원들이 지방으로 이전하기 전 보다는 이후에 크며, 지방으로 이전 한 이후에는 기대심리와 이직의도의 관계가 낮아진다는 점을 실증적으로 규명하였다.
The interplay between hedonic and utilitarian attributes has assumed special significance in recent years; it has been proposed that consumption offerings should be viewed as experiences that stimulate both cognitions and feelings rather than as mere products or services. This research builds on previous work on hedonic versus utilitarian benefits, regulatory focus theory, customer satisfaction to address two question: (1) Is the shopping goal at the point of purchase different from the shopping value? and (2) Is the customer loyalty after the use different from the shopping value and shopping goal? We surveyed 345 peoples those who have bought the electronic-goods within 6 months. This research dealt with the shopping value which is consisted of 2 types, hedonic and utilitarian. Those who pursue the hedonic shopping value may prefer the pleasure of purchasing experience to the product itself. They tend to prefer atmosphere, arousal of the shopping experience. Consistent with previous research, we use the term "hedonic" to refer to their aesthetic, experiential and enjoyment-related value. On the contrary, Those who pursue the utilitarian shopping value may prefer the reasonable buying. It may be more functional. Consistent with previous research, we use the term "utilitarian" to refer to the functional, instrumental, and practical value of consumption offerings. Holbrook(1999) notes that consumer value is an experience that results from the consumption of such benefits. In the context of cell phones for example, the phone's battery life and sound volume are utilitarian benefits, whereas aesthetic appeal from its shape and color are hedonic benefits. Likewise, in the case of a car, fuel economics and safety are utilitarian benefits whereas the sunroof and the luxurious interior are hedonic benefits. The shopping goals are consisted of the promotion focus goal and the prevention focus goal, based on the self-regulatory focus theory. The promotion focus is characterized into focusing ideal self because they are oriented to wishes and vision. The promotion focused individuals are tend to be more risk taking. They are more sensitive to hope and achievement. On the contrary, the prevention focused individuals are characterized into focusing the responsibilities because they are oriented to safety. The prevention focused individuals are tend to be more risk avoiding. We wanted to test the relation among the shopping value, shopping goal and customer loyalty. Customers show the positive or negative feelings comparing with the expectation level which customers have at the point of the purchase. If the result were bigger than the expectation, customers may feel positive feeling such as delight or satisfaction and they would want to share their feelings with other people. And they want to buy those products again in the future time. There is converging evidence that the types of goals consumers expect to be fulfilled by the utilitarian dimension of a product are different from those they seek from the hedonic dimension (Chernev 2004). Specifically, whereas consumers expect the fulfillment of product prevention goals on the utilitarian dimension, they expect the fulfillment of promotion goals on the hedonic dimension (Chernev 2004; Chitturi, Raghunathan, and Majahan 2007; Higgins 1997, 2001) According to the regulatory focus theory, prevention goals are those that ought to be met. Fulfillment of prevention goals in the context of product consumption eliminates or significantly reduces the probability of a painful experience, thus making consumers experience emotions that result from fulfillment of prevention goals such as confidence and securities. On the contrary, fulfillment of promotion goals are those that a person aspires to meet, such as "looking cool" or "being sophisticated." Fulfillment of promotion goals in the context of product consumption significantly increases the probability of a pleasurable experience, thus enabling consumers to experience emotions that result from the fulfillment of promotion goals. The proposed conceptual framework captures that the relationships among hedonic versus utilitarian shopping values and promotion versus prevention shopping goals respectively. An analysis of the consequence of the fulfillment and frustration of utilitarian and hedonic value is theoretically worthwhile. It is also substantively relevant because it helps predict post-consumption behavior such as the promotion versus prevention shopping goals orientation. Because our primary goal is to understand how the post consumption feelings influence the variable customer loyalty: word of mouth (Jacoby and Chestnut 1978). This research result is that the utilitarian shopping value gives the positive influence to both of the promotion and prevention goal. However the influence to the prevention goal is stronger. On the contrary, hedonic shopping value gives influence to the promotion focus goal only. Additionally, both of the promotion and prevention goal show the positive relation with customer loyalty. However, the positive relation with promotion goal and customer loyalty is much stronger. The promotion focus goal gives the influence to the customer loyalty. On the contrary, the prevention focus goal relates at the low level of relation with customer loyalty than that of the promotion goal. It could be explained that it is apt to get framed the compliment of people into 'gain-non gain' situation. As the result, for those who have the promotion focus are motivated to deliver their own feeling to other people eagerly. Conversely the prevention focused individual are more sensitive to the 'loss-non loss' situation. The research result is consistent with pre-existent researches. There is a conceptual parallel between necessities-needs-utilitarian benefits and luxuries-wants-hedonic benefits (Chernev 2004; Chitturi, Raghunathan and Majaha 2007; Higginns 1997; Kivetz and Simonson 2002b). In addition, Maslow's hierarchy of needs and the precedence principle contends luxuries-wants-hedonic benefits higher than necessities-needs-utilitarian benefits. Chitturi, Raghunathan and Majaha (2007) show that consumers are focused more on the utilitarian benefits than on the hedonic benefits of a product until their minimum expectation of fulfilling prevention goals are met. Furthermore, a utilitarian benefit is a promise of a certain level of functionality by the manufacturer or the retailer. When the promise is not fulfilled, customers blame the retailer and/or the manufacturer. When negative feelings are attributable to an entity, customers feel angry. However in the case of hedonic benefit, the customer, not the manufacturer, determines at the time of purchase whether the product is stylish and attractive. Under such circumstances, customers are more likely to blame themselves than the manufacturer if their friends do not find the product stylish and attractive. Therefore, not meeting minimum utilitarian expectations of functionality generates a much more intense negative feelings, such as anger than a less intense feeling such as disappointment or dissatisfactions. The additional multi group analysis of this research shows the same result. Those who are unsatisfactory customers who have the prevention focused goal shows higher relation with WOM, comparing with satisfactory customers. The research findings in this article could have significant implication for the personal selling fields to increase the effectiveness and the efficiency of the sales such that they can develop the sales presentation strategy for the customers. For those who are the hedonic customers may be apt to show more interest to the promotion goal. Therefore it may work to strengthen the design, style or new technology of the products to the hedonic customers. On the contrary for the utilitarian customers, it may work to strengthen the price competitiveness. On the basis of the result from our studies, we demonstrated a correspondence among hedonic versus utilitarian and promotion versus prevention goal, WOM. Similarly, we also found evidence of the moderator effects of satisfaction after use, between the prevention goal and WOM. Even though the prevention goal has the low level of relation to WOM, those who are not satisfied show higher relation to WOM. The relation between the prevention goal and WOM is significantly different according to the satisfaction versus unsatisfaction. In addition, improving the promotion emotions of cheerfulness and excitement and the prevention emotion of confidence and security will further improve customer loyalty. A related potential further research could be to examine whether hedonic versus utilitarian, promotion versus prevention goals improve customer loyalty for services as well. Under the budget and time constraints, designers and managers are often compelling to choose among various attributes. If there is no budget or time constraints, perhaps the best solution is to maximize both hedonic and utilitarian dimension of benefits. However, they have to make trad-off process between various attributes. For the designers and managers have to keep in mind that without hedonic benefit satisfaction of the product it may hard to lead the customers to the customer loyalty.
The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times. C-DAK 4000 (Cordis Dow) and CF IS-11 (Baxter Travenol) reused dialyzers obtained from the dialysis clinic were used in the present study.
