본 연구는 한국에서 시행 중인 탄소배출권 거래제도가 탄소중립을 달 성하는데 효과적으로 기여하고 효율적으로 작동할 수 있도록 정책적 시 사점을 제공하고자 한다. 이를 위해서, 탄소배출권 가격과 전산업생산지 수의 관계를 분석하였다. 즉, 탄소배출권 가격과 전산업생산지수의 선형 및 비선형 관계를 고려하여 경제학적 모형을 통해 추정 및 분석을 진행 하였다. 분석 방식은 구조변화를 반영한 방식과 임계값(문턱값)을 반영하 는 방식으로 나누어 모형을 구축하고 추정하였다. 그 결과, 한국의 탄소 배출권 가격과 전산업생산지수는 추정한 모형에서 비선형적 관계가 포착 되었다. 이러한 결과는 한국에서 시행 중인 탄소배출권 거래제도가 효율 적으로 작동할 수 있도록 추가적인 정책이 필요함을 시사한다. 예를 들 어, 산업 분야에서 저탄소 공정으로의 전환(또는 저탄소 경제로의 전환) 이 완전히 이루어지지 않은 현실을 고려할 때, 여전히 경제가 성장하는 상황에서 비선형 관계가 포착된다는 것은 탄소배출권 가격이 적정한 수 준을 유지하지 못하고 지속적으로 하락하는 추세를 나타낸다는 것이기 때문이다. 따라서, 탄소배출권 거래제도의 본래 취지인 탄소배출량의 감 축에 기여할 수 있도록 적정한 탄소배출권 가격이 배출권 거래제도하에 서 유지되도록 하는 정책을 고려해야 한다.

Effects of pH and salt concentration on rheological and thermal properties of Pacific whiting surimi were investigated. As pH increased from 6 to 7.5, failure shear stress and strain values increased from 15.4 to 31.32 kPa, whereas lightness values (L * ) decreased from 86.22 to 78.86. Storage modulus (G') followed a trend similar to failure shear stress. A linear relationship (r 2 =0.89) was found between G' and failure stress values as a function of pH. Increasing salt concentration up to 1% increased failure shear stress to 27.14 kPa without salt to 34.30 kPa, and strain values from 1.73 to 1.91, whereas further increase had a negative effect. The relationship between dynamic rheological data and failure shear stress was not linear, indicating that salt concentration cannot be used as an index for estimating final gel quality. The transition temperatures obtained from temperature sweep measurements of Pacific whiting surimi at different salt concentrations showed similar peak temperatures as DSC thermograms, indicating lower stability due to increased salt concentration.

The principal objective of this study was to categorize service attributes on the basis of the asymmetric and non-linear relationship existing between service attributes and customer satisfaction. Researchers generally assume that service attribute performances and customer satisfaction are both symmetrical and linear. That is to say, improvements in attribute performance will inevitably result in increased customer satisfaction. However, this is not always the case. Certain attributes have been shown not to create satisfaction even when improved, and others do not create dissatisfaction even when their performance ratings become negative. Understanding this relationship is crucial not only to researchers, but also to service managers. Service managers can arrange their priorities with regard to which attributes must be improved or promoted first, in an environment of limited technical, financial, and human resources. Many studies into this asymmetric and non-linear relationship have recently been conducted, beginning with Herzberg's motivation-hygiene theory (1976) and the disconfirmation theory, which was eventually developed into Kano's model (1984). This study attempted to determine the impact level of service attributes on incidents of satisfaction or dissatisfaction. It used 30 service attributes generated by Park (2008) in the CIT research into family restaurants. The data were collected from 600 participants, 300 incidences of satisfaction and 300 incidents of dissatisfaction, via an online survey. The t-test was used to confirm the difference between the satisfaction group's and dissatisfaction group's attributes. 11 attributes were found to be significant at a level of p>0.05. This indicates that the 11 attributes exerted different impacts on satisfaction and dissatisfaction, which confirmed the asymmetric and non-linear relationship. 14 attributes were categorized into the core service, 1 attribute into the quality service, 7 attributes into the basic service, and 8 attributes into the neutral service. Strategic customer service management was recommended for the 'A' family restaurant as an example, on the basis of the asymmetric and non-linear relationship and the characteristics of the four service factors.
