A series of experiments demonstrated that an addition of Ag into $(Cu_{0.5}Zr_{0.5})_{100-x}Ag_{x}$ amorphous alloys alters the plasticity of the alloys in a systematic manner. Energy dispersive x-ray spectroscopy (EDS) conducted on the $(Cu_{0.5}Zr_{0.5})_{100-x}Ag_{x}$ alloys exhibited the presence of compositional modulation, indicating that compositional separation had occurred. The presence of compositional modulation was also validated using a combined technique of molecular dynamics and Monte Carlo simulation. In this study, the effect of Ag on the compositional separation in $(Cu_{0.5}Zr_{0.5})_{100-x}Ag_{x}$ bulk amorphous alloys was investigated to understand the role played by the phase-separating element on the plasticity of the amorphous alloys.

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 cons

近年来, 享乐和功利属性之间的相互作用被认为具有特殊的意义。诮费产品应被视为一种促进双方感受和认识的经验, 而不是单纯的产品或服务。 本文以先前对享乐与功利的利益的研究, 调节点理论, 客户满意度为基础来讨论两个问题 : (1) 在购买时, 购物目标不同于购物价值吗? (2) 使用后的顾客忠诚度与购物价值和购物目标不冋吗? 我们对在最近六个月内购买过电子产品的345人进行淍查。本研究涉及两类购物价值 : 享乐型和功利型。那些追求享乐型购物价值的顾客比起产品本身, 他们更注重愉快的购物经验。 他们更注重购物的氛围, 购物体验中获得的快感。与先前的研究相一致, 我们用 "享乐" 来指他们的审美, 体验和享受有关的价值。相反, 那些更倾向于功利型消费的顾客更有可能进行理性购买。这可能更具有功能性。与以前的硏究相一致, 我们用 "功利" 来指具有功能性, 工具成和实用价值的消费产品。 霍尔布鲁克(1999) 指出, 消费者价值是一个来自各种利益的消费经验。以手机为例, 手机的电池寿命和音量是功利效益, 而美观的形状和颜色是享乐利益。同样, 如果是汽车, 燃料经济性和安全是功利利益, 而天窗和豪华內饰则享乐利益。 根据自我调节点理论, 购物目标包括堤升调节点目标和防御调节点目标。提升调节点的特征是关注理想的自身, 因为他们关注于理想和愿望。他们对希望和成就更敏感。相反, 防御调节的个体的目标取向是责任, 安全。防御调节点的个体往往更倾向避免风险。 我们想测试购物价值, 购物目标和客户忠诚度之间的关系。顾客相对于购买时的期望水平所表现出积极或消极的情感。如果结果大于预期, 顾客可能会有积极的感觉, 例如高兴或满意, 他们希望与其他人分享他们的感觉。他们希望在未来継续购买这些产品。 具有不同种类目标的消费者期望获得产品享乐层面的满足和期望获得产品功利层面的满足不同(Chernev 2004)。具体来说, 消费者在功利层面期望实现产品防御目标, 而在享乐层面期望实现提升目标 (Chernev 2004 ; Chitturi, Raghunathan, and Majahan 2007 ; Higgins 1997, 2001)。 根据调节点理论, 防御目标是应该被满足的。防御目标的实现可以显著减少甚至消除产品消费中痛苦的经历的概率。从而使消费者拥有自信和安全的消费情绪。 相反, 提升目标的实现是人们渴望自己看来很酷或很成熟的要求被满足。在产品消费的背景下, 堤升目标的实现可以显著增加愉快的经历的概率。提出的概念框架分別讨论享乐和功利的购物价值之间的关系以及提升和防御的购物目标之间的关系。 对功利和享乐价值是否实现而产生的结果的分析是具有理论价值的。同时也具有实践意义。因为它 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.

인적자원관리는 노동조합을 대체하는가? 2005-2011 사업체패널조사를 이용한 실증분석

박경원 ( Kyoung Won Park ),김동배 ( Dong Bae Kim ) 한국산업노동학회 2014 산업노동연구 Vol.20 No.3

본 연구는 노동연구원의 2005-2011 사업체패널조사를 이용하여 인적자원관리의 노동조합 대체효과를 검증하였다. 패널분석의 고정효과모델을 기반으로 한 실증결과는 다음과 같다. 첫째, 사업체내 연봉제와 자율작업팀의 도입은 노동조합 조직률과 통계적으로 유의한 부(-)의 영향을 미친 반면 소집단활동과 직무순환제의 도입은 유의한 정(+)의 영향을 미쳤다. 둘째, 개별 인적자원관리 관행들의 합으로 측정한 HRM 시스템 지수는 정(+)의 영향을 미쳤지만 통계적으로 유의하지 않았다. 셋째, 사용자의 노동조합 전략은 노동조합 가입률에 유의한 영향을 미친 반면 육성형 HRM 정책은 유의하지 않았다. 마지막으로, 위 결과들은 개별 인적자원관리 관행들의 2년 시차변수들을 이용한 분석에서도 그 영향의 방향이 일관되게 나타났다. 본 연구의 결과는 인적자원관리와 노동조합 간에 대체성과 보완성이 서로 공존하며, 그 총효과는 서로 상반되는 효과 중 어느 효과가 더 지배적인가에 의해 결정됨을 시사한다. This study empirically tests whether Human Resource Management (hereafter HRM) substitutes for unions using the Korea Labor Institute’s 2005-2011 Workplace Panel Survey. The results from the fixed effect model are as followings. Firstly, the adoption of merit pay system and autonomous team significantly reduced the union membership rate, whereas the adoption of quality circle and job rotation significantly increased the union membership rate. Secondly, an HRM system index, measured with the sum of individual HRM practices, appeared to be positive to the union membership rate, but not statistically significant. Thirdly, union suppression by employers significantly reduced the union membership and the employer-union partnership significantly increased the union membership rate. However, employers’ HRM policy did not. Finally, these results were consistent with those with the use of two-year lagged variables. This study concluded that HRM and unions were both substitutable and complementary, and the total effect would depend on which one dominates the other.

학술연구 : IT 기업 시장지향성에 따른 프랜차이즈 유통의 갈등에 관한 연구: 전자 제품 판매 프랜차이즈를 중심으로

박경원 ( Kyoung Won Park ),최인혁 ( In Hyok Choi ),박주영 ( Ju Young Park ) 한국중소기업학회 2010 기업가정신과 벤처연구 Vol.13 No.4

최근에 마케팅 분야에서 주목받고 있는 연구영역인 시장지향성이 기업의 사업성과에 긍정적인 영향을 미치는 이유에 대한 설명을 하기 위하여 국내 대효적인 IT 기업의 제품 유통 프랜차이즈를 대상으로 연구하였다. 프랜차이즈 관계를 영위하는 가맹본부에게 있어서 자사 제품을 판매하는 가맹점들은 1차 고객이자, 최종 소비 고객을 상대해야 하는 유통으로서 판매원의 역할을 수행한다. 따라서, 판매력이 우수한 가맹점과 안정적이고도 장기적인 협력 관계를 유지하는 것이 가맹본부에게 있어서는 사업성과에 필수적인 요소라고 할 수 있다. 본부와 가맹점의 관계에서 가맹점이 본부의 시장지향성에 대한 태도가 가맹점의 만족, 관계지속의지 및 프랜차이즈 시스템 내에서 가맹점이 인식하는 갈등에 각각 어떤 영향을 미치는지 살펴보았다. 본부의 시장지향성을 고객지향성, 경쟁자지향성 내부협력 3개 요인으로 구분하여 검증한 결과, 본부의 시장지향성을 높게 인식한 가맹점은 프랜차이즈 관계에서 가맹점의 만족 역시 높게 나타났으며, 가맹점의 만족은 관계지속의지와 정(+)의 관계가 있는 것으로 나타났다. 반연 프랜차이즈 관계에서 가맹점의 본부에 대한 만족은 본부와 가맹점간 갈등을 줄여 주는 부(-)의 관계가 있는 것으로 나타났다. 본부와 프랜차이즈 가맹점 관계에서 본부의 고객지향성, 경쟁자지향성, 내부협력 요소로 구성되는 시장지향성의 확보를 통한 가맹점의 만족이 바람직한 프랜차이즈 관계 발전에 필수 요소라고 해석될 수 있을 것이다. This study attempted to investigate comprehensively the impact of market orientation on satisfaction, long-term orientation and conflict in the domestic representative IT company franchise channel system. To attain the objectives, it reviews literatures concerning the relationship between suppliers and retailers, particularly with regard to such as market orientation and long-term orientation. The market orientation consists of 3 constructs: customer orientation, competitor orientation, and inter-functional coordination. Data collected from 147 sales franchise store owners supported major hypothesis that were imposed in accordance with the results. The following conclusions were made; the market orientation of headquarters perceived on the franchisees is very important to establish satisfaction. And the satisfaction influence the franchisees to have long-term orientation. In addition, the satisfaction of franchisees reduces the conflict between the headquarters and franchisees. The significance of this study is that market orientation may help to establish the sound relationship between the headquarters and the franchisees as a component for satisfaction and mutual development.

Studies of a number of Cu-Zr amorphous alloys have demonstrated that those exhibiting greater plastic strain during homogeneous deformation at room temperature show lower global plasticity associated with inhomogeneous deformation in a typical compression test. Using a combination of experiments and molecular dynamics simulations, we clarify this seeming paradox between the homogeneous and inhomogeneous deformation by exploring the microstructural aspects in view of the structural disordering, disorder-induced softening, and shear localization and relate these findings to the global plasticity of bulk amorphous alloys. Additional analyses were conducted to derive a simple structural parameter that allows the prediction of the global plasticity of bulk amorphous alloys.

노사관계 분위기의 시간과 노사 관점 차이에 따른 변화 분석

박경원(Kyoung Won Park) 한국고용노사관계학회 2017 産業關係硏究 Vol.27 No.3

본 논문은 한국노동연구원의 사업체패널 조사를 이용하여 2005년부터 2013년까지 9년 동안 사업체의 노사관계 분위기가 얼마나 안정적인가(또는 일관되었는가)를 분석하였다. 이를 위해 일반화가능도이론을 응용하여 측정시점 5회와 노사 양측 대표 1인으로 구성된 측정상황 하에서 노사관계 분위기의 평가에서 발생하는 체계적 오차 요인인 측정시점과 노사 관점 차이의 상대적 비중과 일반화가능도 계수를 추정하였다. 분석결과 노사관계 분위기의 총분산에서 사업체 차이에 의한 분산이 가장 크게 나타났으며, 이는 같은 기간 사업체의 노사관계 분위기가 상당히 안정적이었음을 보여준다. 사업체와 측정시점 간 상호작용 효과에 의한 분산이 두 번째로 크게 나타났으며, 이는 특정 시기 사업체 수준의 전략적·정책적 변화가 노사관계 분위기 변화에 영향을 미쳤음을 보여준다. 반면 측정시점과 노사 관점 차이의 주 효과와 사업체와 노사 관점 차이 간 상호작용 효과에 의한 분산은 크지 않은 것으로 나타났다. 마지막으로 본 연구결과가 제시하는 사업체 노사관계 분위기의 변화 가능성에 대한 함의를 논의한다. This paper analyzes how industiral relations climate was stable (or consistent), using the 2005-2013 workplace panel survey. Applying the analytical procedures of the generalizability theory to the measurement condition in which industrial relations climate was repetitively evaluated by two raters (one from a labor union and the other from management) in five occasions, this paper estimates the ratio of variances due to time and difference in the perspective of labor and management and due to their interaction with establishments to the total variance in industrial relations climate and the generalizability coefficients. The main results are two-fold. First, the variance due to establishments explained the largest portion of the total variance in industrial relations climate. Second, the variances due to the occasions and the raters and due to their interactions with establishments explained the relatively small portion of the total variance. These results suggest that industrial relations climate during the past 9 years was of considerable stability. And this paper discusses the implications of these results to the changeability of industrial relations climate of establishments in Korea.
