Consumer innovativeness is a force that leads to innovative behavior of consumer and it is crucial for companies to understand the innovativeness in association with the new innovative product adoption. The purpose of this paper is to examines the influence of Consumer's inherent innovativeness, product involvement, and product expertise on consumers's vicarious and adoptive innovativeness. For this purpose, the model has been set and examined the influence of consumer innovativeness, product involvement and product expertise on vicarious and adoptive innovativeness. The results revealed that 1) consumer innovativeness would not influence vicarious and adoptive innovativeness, 2) vicarious innovativeness had affect on adoptive innovativeness 3) product involvement had a affect on both vicarious and adoptive innovativeness 4) product expertise had a affect on vicarious innovativeness and yet had no affect on adoptive innovativeness.

The purpose of study was to investigate internal and external problem behavior according to types of multiple-attachments exhibited to both mothers and teachers. The subjects were 120 preschool children (between 4 to, -5 years old), their mothers and teachers. The attachment classification of these 120 preschoolers was evaluated by an attachment Q-set. Data was statistically analyzed by means of one-way ANOVA, and the Duncan test with the SPSS Win 13.0 program. Our results were as follows, Firstly, significant differences were observed in the internal problem behavior according to types of multiple-attachments. Second, significant differences were also observed in the external problem behavior according to types of multiple-attachments. This study suggests that secure attachment relationships with teachers may compensate for insecure relationships with mothers.

In this paper, the efficient periodic unsteady flow analysis is developed by using a Chebyshev collocation operator applied to the time differential term of the governing equations. The partial implicit time integration method was also applied in the governing equation for a fluid, which means flux terms were implicitly processed for a time integration and the time derivative terms were applied explicitly in the form of the source term by applying the Chebyshev collocation operator. To verify this method, we applied the 1D unsteady Burgers equation and the 2D oscillating airfoil. The results were compared with the existing unsteady flow frequency analysis technique, the Harmonic Balance Method, and the experimental data. The Chebyshev collocation operator can manage time derivatives for periodic and non-periodic problems, so it can be applied to non-periodic problems later.

For construction companies to become competitive innovative, cost management as well as process improvement are required. Activity-based costing (ABC), which uses cost information to support long-term decision-making, is a tool that enhances a company's competitiveness. In this study, we compare and analyze tradition-based costing (TBC) and ABC to confirm the adequacy of performance-based costing. In addition, we will empirically examine the relationship between the impact of the reward system using ABC on employee satisfaction and involvement. In research results, the influence of the reward system on employee involvement appeared in the order of intrinsic reward (𝛽 = 0.338) and extrinsic reward (𝛽 = 0.308). In addition, the reward system showed positive (+) effects on employee satisfaction, with influence appearing in the order of intrinsic reward (𝛽 = 0.360) and extrinsic reward (𝛽 = 0.337). And employee satisfaction (𝛽 = 0.225) had a positive effect on involvement. We were able to confirm that it is necessary to build a reward system consisting of intrinsic and extrinsic rewards to increase employee satisfaction and involvement.

The objective of this study is to investigate factors influencing user's intention to use by expanding TAM(Technology Acceptance Model). Based on this model, this study developed a comprehensive model and user's motivation factors such as extrinsic and intrinsic motivation to describe their intention to accept WCDMA service. For this purpose those who have subscribed to and use the current mobile communication service - all of whom were 13 to 49 years old living in Seoul or other large cities - were surveyed. Structural equation model was conducted to identify and validate the relationship of overall variables relating to mobile service acceptance. The analysis results indicate that intrinsic motivations in mobile service acceptance process have significant impacts on perceived usefulness and perceived ease to use. The results of this study also proposed the way to boost mobile service user's extrinsic and intrinsic motivation for coming up with strategies on how to improve effectiveness of communication and marketing. Future directions and limitations are also discussed.

This study examined the effects of work values and the career decision level on the major commitment of the university students majoring in social welfare. For this purpose, a survey of 351 undergraduate students majoring in social welfare at 4 universities located in Kangwon-do was conducted and the data were analyzed. The work values consisted of intrinsic values and extrinsic values. The career decision level was measured by the career decision scale (CDS) and the major commitment was measured by the flow state scale (FSS). The research findings are as follows. First, the career decision level (3.43) and major commitment (3.58) of the university students majoring in social welfare were slightly higher than the mid-point on the 5 point Likert scale. In addition, the intrinsic work value (4.05) were higher than the extrinsic work value (3.34). Second, the intrinsic work values and career decision level were positively correlated with the major commitment. Third, the extrinsic work value had a negative effect on the major commitment (${\beta}=-.34$, p<.001); however, the intrinsic work value (${\beta}=.31$, p<.001) and career decision level (${\beta}=.18$, p<.001) had a positive effects on the major commitment. This paper also discusses the theoretical and practical implications for university student's work values, career decision level, and major commitment based on the research findings.

본 논문에서는 노동자문화정치의 관점에서 파업을 새롭게 정의하고, 파업을 비롯한 노동자 문화실천의 정치적 효과를 분석하기 위한 방법론적 요소들을 검토하였다. 여기서 파업은 참여주체들의 다양한 사고와 합리성들을 중심으로 형성되고 확장되는 내재적인 정치의 장인 동시에, 다양한 기표적 실천들이 전개되는 문화정치의 장으로 정의되었다. 파업의 발생과 전개의 각 과정과 국면에 대한 문화정치적 분석 요소로서 장소성, 공간, 시간, 정서, 기호자원, 담론이 고려되었고, 이 요소들에 초점을 두고 민주노조 파업에서 드러나는 문화정치적 제약들을 H사 노조 사례를 통해 검토하였다. 문화정치적 제약들은 노동자 문화의 생산과 수용에서의 제약으로 드러난다. 노동자문화 관련 텍스트들의 분석과 조사 자료를 통해서 볼 때, 그것들은 첫째로 노동자 문화 활동가들의 생산 실천 상의 제약과 관련있고, 둘째로, 노동자 대중의 노동자 문화 수용 혹은 소비에서의 도구성과 시 공간 상의 제약과 관련있는 것을 확인했다. 본 논문은 이러한 제약들이 70년대 이후에서 90년대 전반에 이르는 시기와는 달리, 현 시기 노동운동의 문화적 자원들이 신기술과 사회문화적 변화에 걸맞게 변화 확장되지 못하고 오히려 축소된 데 기인한다고 추론하였다. 따라서 지속적인 운동의 조건과 기반을 능동적으로 조성하기 위해서는, 파업을 비롯한 노동자 문화의 생산과 수용 전반에 걸쳐서 작용하는 재현체계 상의 제약, 특히 기호자원의 한계라는 근본적인 제약을 넘어서기 위한 노동자 문화정치의 필요성이 제안되었으며, 문화실천에 몸담고 있는 문화활동가나 노조활동가들이 파업과 일상 활동 속에서 문화정치적 주제들을 찾아 이론화하고 정책에 반영하는 문화활동 방안이 제안되었다.

The relative extrinsic value orientation (REVO) means the relative importance to extrinsic values (e.g. wealth, fame and social approval) compared with intrinsic values (e.g. affiliation, self-acceptance and personal growth). This study aimed to investigate the causal relation between REVO and life-satisfaction using the auto-regressive cross-lagged modeling. For this purpose, 3rd, 5th, and 7th year data from the Korea Children and Youth Panel Survey (KCYPS) middle school 1st grade panel was analyzed (N = 2,259; 1,140 males and 1,119 females). The results are as follows; Firstly, positive auto-regressive effects of REVO and life-satisfaction were significant. Secondly, REVO was found to have negative and cross-lagged effect on life-satisfaction. However, cross-lagged effect from life-satisfaction to REVO was not significant. Finally, no gender difference was found in this relationship. These results suggest that low life satisfaction does not cause the relative extrinsic value orientation, but high relative extrinsic value orientation may cause low life satisfaction.

We test the hypothesis whether foreign direct investments(hereafter "FDI") can affect the changes of the firm value. In this study, we use a newly developed event study technique, referred to as value-based event study approach(hereafter "VESA"), which is based on the seminal papers of M&M(1958, 1961, 1963) and Lee(2006, 2007). The empirical findings about the effects of FDI's on the intrinsic firm values, which can be measured by intrinsic Q(hereafter "IQ") values of the VESA, are as follows; First, the FDI's are carried out by healthy firms in terms of high IQ's. The IQ values become higher during the post-FDI period than prior to performing FDI's. Second, among the four components of IQ values, the value of assets-in-place, the value of intangible assets, and the value of growth opportunities are all increased during the post-FDI period, except the value of current earnings. Third, the same results are observed in all the samples classified by industry. In sum, thanks to the above findings in this study, we can conclude that the announcements of the FDI's are good and reliable indicators for the firm to signal to the market that the FDI firms are healthy in intrinsic firm values, and also that they have good chances to increase their firm values through the new investments abroad.

Creativity is an essential ability for a successful design task, mainly because design is an activity creating something new. As the sphere of design has expanded and become complex, the design task goes beyond an individual designer's capability. Therefore, it is necessary to organize a design team consisting of various team members with diverse expertises. The aim of this study is to find out the impact of fundamental attributes of members on the group creativity in order to establish a guideline for building a creative design team. Heterogeneous teams and homeogenous teams were created according to three main factors of group creativity namely, personality, field and experience. The group creativity of each team were evaluated through protocol analysis of design activities as well as the comparison of problem solving processes and outputs. It was identified that the impact of design teams on the group creativity was distinctively different in four phases of the design process (preparation, divergence, convergence, and execution) regarding creativity properties such as fluency, elaboration, originality, usefulness. Based on these findings, a schematic model for building a design team in order to enhance the group creativity by composing the most appropriate team members for each phases of the design process was developed.
