The ability of smartphones to facilitate various services like mobile banking, e-commerce and mobile payments has made them part of consumers' lives. Conjoint analysis (CA) is a marketing research approach used to assess how consumers' preferences for products or services develop. The potential applications of CA are numerous in consumer electronics, banking and insurance services, job selection and workplace loyalty, consumer packaged goods, and travel and tourism. Choice-Based Conjoint (CBC) analysis is the most commonly used CA approach in marketing research. The purpose of this study is to utilise CBC analysis to investigate the relative importance of smartphone attributes that influence consumer smartphone preference. An experiment was designed using Sawtooth CBC Software. 326 students attempted the online survey. Utility values were derived by Hierarchical Bayes (HB) estimation and used to explain consumers' smartphone preferences. All the six attributes used for the study were found to significantly influence smartphone preference. Smartphone brand was the most important, followed by the price, camera, RAM, battery life, and storage. This study is one of the first to use Sawtooth CBC analysis to assess consumer smartphone preference based on the six attributes. We provide implications for the development of new smartphones based on attributes.

The purpose of this study is to make special study of the efficient operation of university foodservice. The concrete results through the conjoint analysis can be elicited as follows. First, through the interview in depth we draw out the efficient attribute comparing and analyzing elements of selecting menu and main reasons for selecting either student cafeterias or general cafeterias. Second, we elicit the best attribute based on the results of analysis on preference. Third, we present an improvement program for operating student cafeterias through simulation. As a result of conjoint analysis of the main reason for selecting a cafeteria and the utility of each attribute, the most important factor comes price (34.95%), the time required (33.20%), food taste (30.45%), and various menu (1.42%) in that order. What draws attention in the research is that price (34.93%) is not the only factor which influences students' choice of a cafeteria. Location (33.20%) and food taste (30.45%) are all equally important. These results show that students' expectation for cafeterias is getting various. Basically, all customers look for a nearer restaurant where its food taste is good and menu is various at a low price.

This study was carried out to suggest method which can be used to improve competitive power of theme parks. The characteristics of Hybrid Conjoint Analysis were described and its usefulness for identification of specific types of service theme parks have to provide was tested "Lotte World, " "Seoul land," and "farmland" were selected as study areas, and .7 attributes with 3 levels were utilized for analyses. Master design with 81 profiles was constructed to meet the requirement of ′Compromise Plan 1,′and data was collected by in-personal interviews on the study areas. Respondents were grouped by cluster analysis, and their characteristics were analyzed by discriminant analysis. Then, part-worth of each attribute . was estimated by stagewise estimation model Calibrated model of each group did not show part-worths of attributes clearly because both main effects and 2-way interaction effects were included in the models. Therefore, calibrated models′ coefficients were used to calculate utilities of all possible combinations of attributes levels. The results showed that managers of theme parks have several options for providing a new service: the combination of attribute levels with the highest utility is they however, they can choose the other combinations with next highest utlities is they can not afford it. Several suggestions were described to cope with the problems when Hybrid Conjoint Analysis is applied to landscape architectural study.

The sales volume of men's cosmetics has drastically increased in Korea. In recent years, men's needs for cosmetics have been diversified and the consumer demand for functional cosmetics has greatly risen. In particular, male consumers have become more interested in essence product that is a light and concentrated treatment to correct skin problems. This research analyzes consumer preferences for essence-for-men through the use of choice-based conjoint analysis. This approach is adopted since the task of respondents to choose the most preferred option from several alternatives closely mimics actual marketplace purchasing behavior by consumers. New technique for the construction of choice sets is suggested based on the balanced incomplete block design, to accommodate a larger number of product profiles. The proposed design for choice sets is balanced and provides a tool to filter the contradictory choices. Conjoint analyses are performed to assess the relative importance of attributes and identify the most preferred profile of essence-for-men with respect to attributes such as emphasized function, price, type of content, and design of container. Some differences are indicated in the analysis results between age brackets as well as between groups classified by the amount of fashion item expenditures.

In this study, a conjoint analysis was conducted to derive a combination of fishing quota management system by fish species preferred by fishermen. In the analysis, detailed levels were set according to each attribute of the system. For analysis, this study conducted a design question survey for conjoint analysis on 303 fishermen engaged in fishing activities in the offshore and coastal sea. The Conjoint analysis was conducted on all fishermen, offshore fishermen and coastal fishermen. In addition, an analysis was conducted on TAC system participants and non-TAC system participants, and the targets were classified for comparison according to the characteristics of fishermen. Fishermen's preference for the system confirmed for six attribute ("catching fish even if there is no fishing quota", "how to allocate fishing quota", "fishing quota management agency", "upper limit of fishing quota," "Possibility of Trading in the Fishing Quota", and "Application of Other Regulations.") and the detailed level of each attribute. As a result of the analysis of the importance of attributes, fishermen thought that "fishing quota management agency (24.1%)" was very important, and "catching fish even if there is no fishing quota (23.9%)" and "how to allocate fishing quotas (22.9%)" were also given some importance.

The focuses and methods in Library science have been changed abreast with the development af library facilities and with the expansion and diversification of its functions. One of current trends in Library science is focussed on the social functions of library: its relations to the public, effective service for the users. and efficieniencies of the management policies, and so. on. To. deal with these issues, we need to borrow methodology from other disciplines such as management, marketing, statistics, etc. This paper is mainly concerned with how we approach to the measurement af services and thus provide tentative standard for evaluating library services. To do. this work properly, we'd better consider the users' needs and expectations. But it is not an easy work since too many factors are involved in the study of the users' needs. Users' needs and expectations are so. varying that it is difficult to find out some general and objective data. That is the reason why although many scholars have urged time after time the necessity of library's effectiveness measurement, few studies demonstrated substantial method for measuring the effectiveness of service. In this paper I propose a device for measuring service: i. e, Conjoint Analysis. Conjoint Analysis, which has originally been developed and applied in marketing research, is used to measure the priorities and preferences of purchasers on the new item. So far as Conjoint Analysis, concerning users' physical and psychological necessities, can numeralize people's needs, it may also be applied to measure service provided by nonprofit organization like library. If this approach prove to be sucessful, I hope this study to make any contribution to the appropriate direction on improving library facilities based on the result from a concret reference evaluation.

제품이나 서비스에 대한 소비자의 선호도에 영향을 미치는 주요 속성들의 중요도를 평가하고 각 속성의 수준에 대한 선호도를 측정하며 제품프로파일에 대한 선호도를 예측하기 위하여 컨조인트분석이 사용되는데, 제품 포지셔닝이나 신제품 개발 분야에 이분석이 많이 활용되고 있다. 본 논문에서는 체비쉐프추정에 바탕을 둔 컨조인트분석에 관하여 연구하였는데, 소비자로 하여금 제품프로파일별 선호도를 순위로 응답하게 하는 경우 최소자승추정에 의 한 컨조인트 분석의 효율성이 상대적으로 낮다고 판단되기 때문이다. 따라서 새로운 개념의 휴대전화기에 대한 소비자들의 선호도를 조사하고 체비쉐프추정에 의한 컨조인트분석을 실행하여 신제품 개발에 활용하도록 하였다. 추정 방법 별로 예측타당성을 측정하여 비교하였는데, 체비쉐프추정에 의한 컨조인트분석이 최소자승추정에 의한 컨조인트분석보다 타당성이 높다는 사실을 확인하였다.

순위기반 컨조인트분석은 마케팅조사를 비롯한 다양한 분야에서 널리 활용되고 있다. 이 분석기법은 다른 기법들에 비하여 몇 가지 장점을 가지고 있는 반면에, 응답자들이 다수의 제품프로파일들에 대한 선호도 순위를 정확하게 평가하기 어렵다는 한계를 가지고 있다. 본 논문에서는 응답효율성을 향상시키기 위하여 순위집합 개념을 도입한 새로운 선호도 측정방법을 제안한다. 응답자에게 순위집합들에 포함된 소수의 프로파일들에 대한 선호도를 순위로 평가하게 한 후 평가결과를 종합하여 프로파일 전체에 대한 순위를 얻는 방법이다. 이 방법에 의하면 응답자가 프로파일들에 대한 선호도 순위를 매기는 작업을 용이하게 할 수 있고 선호도 순위를 효율적으로 평가할 수 있다. 한편, 다수의 프로파일을 수용할 수 있는 순위집합을 체계적으로 구성하기 위하여 균형불완비블록설계를 확장하여 쌍체설계로 전환시키는 방법을 개발하였다. 제안된 측정방법을 채택한 순위기반 컨조인트분석을 여성용 향수제품에 대한 소비자 선호도분석에 실제로 적용하였다.
