김종오,노권재,윤여헌,고영도,유재두,정준모,방한천,정재학 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목 적: 노령의 대퇴 전자간 골절에서 압박고 나사못의 안정성에 영향을 주는 인자들간의 상관 관계와 골절 양상에 따른 술후 고관절 기능을 평가 및 분석하였다. 대상 및 방법: 압박고 나사를 이용하여 수술적 치료를 시행한 231명의 환자 중 6개월 이상 추시가 가능하였던 60세 이상 84명의 환자들을 대상으로 했다. 방사선적 계측은 압박고 나사못의 활강 길이 및 내반각, 가압 나사 위치, 정복 상태, 원위 골편의 내측 전위를 측정하였으며 술후 기능은 Clawson의 기능 평가표로 하였고 골절 양상에 따라 방사선 계측과 기능 회복과의 상관 관계를 평가하였다. 결 과: 임상 결과는 불안정 골절에서 양호가 10례, 불량이 23례, 안정 골절에서는 양호 40례, 불량이 11례로 안정 골절에서 임상 결과가 좋았고(p<0.001), 압박고 나사 활강은 10 ㎜ 이상일 때 양호가 4례, 불량이 21례, 10 ㎜ 이하에서 양호가 46례, 불량이 13례로 10 ㎜ 이상 활강시에 술후 결과가 불량했다(p<0.001). 다르 방사선적 계측 요인은 결과에 의미있는 차이를 보이지 않았다. 또한, 불안정 골절 중에서 전위 양상 골절의 경우 10㎜ 이상 활강이 12례, 10㎜ 이하 활강이 8례, 분쇄 양상 골절의 경우는 10㎜ 이상이 11례, 10㎜ 이하가 2례로 분쇄 양상의 불안정 골절에서 10㎜ 이상 활강이 의미있게 많았다 (p<0.001). 결 론: 10㎜ 이상의 지연 나사 활강은 고관절 기능 회복 약화를 유발시킬 수 있으며 불안정 골절 분쇄 양상 골절은 이런 지연 나사의 활강이 과도하게 유발될 수 있으므로 불안정 분쇄 양상 골절에서 압박고 나사의 단독 사용은 재고해 보아야 할 것이다. Purpose: To evaluate the relationship between fracture stability and functional results, and analyze the correlation between stability factors and the outcome in intertrochanteric fracture of the elderly. Materials and Methods: Of the 231 patients, 84 patients with age above 60 were able to follow up for minimum 6 months. We measured the sliding length of the lag screw, varus degree, position of lag screw, reduction status and medialization of distal fragment radiologically. The functional outcome of the treatment was evaluated with the Clawson's result classification and we evaluated the correlation between the radiological results of measurement and the functional recovery depending on the Evans fracture classification. Results: There were good results in 40 cases out of 51 stable fractures, and in 10 cases out of 33 unstable fractures (p<0.001). In case of sliding of lag screw more than 10㎜, good results were obtained in 4 cases, and poor in 21. And in case of sliding less than 10㎜, good results were obtained in 46, and poor in 13. (p<0.001).But there was no relationship between other radiologic factors and clinical results. In unstable type, there were 12 cases with lag screw sliding more than 10㎜ and 10 cases with less than 10㎜. In comminuted type, there were 11 cases with lag screw sliding more than 10㎜ and 2 cases with less than 10㎜(p<0.001). Conclusion: The sliding of lag screw more than 10㎜ may result in poor outcome. As in comminuted unstable pattern, sliding of lag screw might be excessive, the use of compression hip screw alone is not good treatment option.

Corporate Social Responsibility in International Marketing Channels: A Focus on Korean Multinational Enterprise-Overseas Distributor Relationships

Han-Mo Oh 한국무역연구원 2014 貿易 硏究 Vol.10 No.3

The objective of this paper is to understand the effects of multinational enterprises corporate social responsibility engagement on channel performance in foreign markets. Research addressing CSR activities of an MNE in international marketing channels is scarce. Specifically, researchers have neglected to study the effects of Korean MNE s CSR efforts on the outcomes of their foreign partners. Therefore, it is necessary to study on international marketing need to focus on how an MNE s CSR activities influence channel relationships outcomes. The present study provides guidance as to the effectiveness of MNEs CSR activities in international marketing channels. Drawing on the stakeholder theory and relationship marketing theory, the current study develops and empirically tests a framework of the influence of an MNE s CSR engagement on channel relationship. Findings from an examination of 116 MNE subsidiary-channel partner dyads reveal positive effects of two facets of an MNE s CSR efforts on channel performance through distinct mechanisms. Ethical CSR enhances channel partners trust, whereas philanthropic CSR increases relationship commitment. This study distinguishes an MNE s actual CSR engagement and channel partners perception of these CSR activities.

Antecedents and Outcomes of Market Orientation in Export Relationships : An Examination of Korean High-tech Ventures

Han-Mo Oh 한국무역연구원 2018 貿易 硏究 Vol.14 No.1

High-tech ventures with limited export marketing resources can compete in overseas markets by building relationships with export intermediaries. Although export relationships are strategically important, there is little understanding of the value that these relationships can create. The present study first develops a concept of market orientation in export relationship marketing. Next, depending heavily on the resource-advantage theory of competition, the study develops an empirically testable model that identifies key antecedents and outcomes of market orientation in export relationships. The model was tested with primary data collected from a survey of Korean High-tech ventures’ export marketing activities. The data were analyzed using a structural equation modeling technique. The findings of the study show that export-venture market orientation should be considered an idiosyncratic resource that allows the venture to achieve superior new product performance in export marketplaces, that export relationship competence can positively lead to export-venture market orientation, and that relational characteristics can affect export-venture new product performance. The current study provides several theoretical implications by offering a richer definition of new product performance for export marketing, by identifying key antecedents of export-venture market orientation, and extending R-A theory to the field of export marketing.

Factors Affecting Firm Value Changes Following Foreign Brand Acquisitions: Conceptualization and Propositional Development

Han-Mo Oh 한국무역연구원 2017 貿易 硏究 Vol.13 No.3

Acquiring foreign brands enable firms to efficiently and effectively compete internationally and globally by changing their brand portfolios while lowering risk. Therefore, foreign brand acquisitions can be a crucial strategy for a firm that desires to enter a foreign market. Despite this strategic importance, there have been few studies on factors affecting firm value changes following foreign brand acquisitions. Drawing heavily on the belief that the stock return to an international marketing strategy signifies long-term financial performance, the present study aims to identify factors affecting firm value changes after foreign brand acquisitions. A conceptual framework was developed, based on the resource-based theory of firm, to explain factors affecting firm value changes after foreign brand acquisitions. The current study proposed that foreign brand acquisitions provide positive returns and that these returns are larger when the target brand is strong. In addition, two types of three-way interactions were proposed. One is among the presence of a brand management system, fit between the target and acquirer’s brands, and brand strategy. The other is among the presence of a brand management system, fit, and diversification level.

The Effect of Global Logistics Firms’ Engagement in Social Responsibility on Customers’ Perception of Price Fairness

Oh, Han-Mo(오한모) 한국물류학회 2016 물류학회지 Vol.26 No.5

일반적으로 고객들은 기업의 사회적 책임 활동에 대해 긍정적인 반응을 나타내는 것으로 알려져 있다. 기존 문헌들 역시 기업의 사회적 책임활동이 기업 경영의 바람직한 성과에 대한 긍정적인 영향을 미치는 것을 입증해 왔다. 그러나 글로벌 배송기업의 사회적 책임활동이 고객 애호도와 같은 바람직한 성과의 원동력인 될 수 있는 고객들의 지각된 가격 공정성에 미치는 영향에 대한 검증은 미비하다. 특히, 글로벌 배송기업의 서비스 가격에 이러한 기업의 사회적 책임활동 수행비용이 포함되는 경우 이를 고객들이 어떻게 받아들일지에 대한 검증이 필요하다. 본 연구에서는 글로벌 배송기업의 사회적 책임활동과 고객들의 지각된 가격 공정성의 관계와 이 관계가 고객들에게 내재된 기업의 사회적 책임활동에 대한 속성에 의해 조절되는지를 검증하였다. 이러한 검증을 위해 피실험자 간 실험 디자인을 통해 수집된 자료를 바탕으로 실증분석이 이루어졌다. 본 논문에서는 이론적으로 글로벌 배송기업의 사회적 책임활동과 고객들의 지각된 가격 공정성, 그리고 고객들의 사회적 책임활동에 대한 내재적 속성의 관계를 설명하는 개념적 모형이 제시되었다. 또한 실무적으로 글로벌 배송기업들에게 고객들의 지각된 가격 공정성에 대한 기업의 사회적 책임 활동의 효과를 최적화하기 위한 전략이 제시되었다. Although many logistics firms engage in corporate social responsibility (CSR) activities, prior research has little investigated the effects of those firms’ engagement in CSR on customers’ perception of price fairness. Drawing on the social exchange theory and the instrumental stakeholder theory, the author develops a conceptual framework that can explain the effect of global logistics firms’ CSR engagement on perceived price fairness and the moderating role of customers’ intrinsic attribution of CSR. A between-subjects scenario experiment was conducted to manipulate participants’ perceived level of a global logistics firm’s engagement in CSR. The effects of the experimental treatment were analyzed with an analysis of variance. The results of the analysis shows that customers’ perception of price fairness is significantly lower in the experiment group than in the control group and that customers’ perception of price fairness is significantly higher for high intrinsic CSR attribution than for low intrinsic CSR attribution. The findings of the present study propose an underlying psychological mechanism liking global logistics firms’ engagement in CSR to customers’ perception of price fairness, in which the perception depends crucially on customers’ CSR attribution. Finally, the author suggests strategies for global logistics firms to optimize the effect of CSR engagement on customers’ perception of price fairness.

Postentry Branding Strategy Affecting Purchase Intention in a Country-Related Product Association Context : Evidence from Korean Consumers

Han Mo Oh 한국무역연구원 2015 貿易 硏究 Vol.11 No.4

It seems common sense that a product’s country-of-origin affects consumers’ purchase decisions. Nonetheless, prior studies do not satisfactorily address how postentry branding strategy affects consumer purchase intentions in a country-related product association context. Based on the perspective of country-of-origin, the current study aims to explore the effect of postentry branding strategy on consumer purchase intentions in a country-related product association context. An experimental study is conducted in a host country market with country-related product associations in terms of cars. A 3 (postentry branding strategies: foreign brand, and foreign-local co-brand, and local-foreign co-brand) × 2 (country-related product associations: strong favorable vs. unfavorable) between-subjects factorial design is used. The results of the experiment present that in a low country-related product association, consumers prefer the foreign products with local-foreign co-brands to ones with the other brand types. In contrast, in a high country-related product association, there is little difference of consumers’ purchase intention among postentry branding strategies. The present study provides empirical evidence on how country-related product associations can affect consumers’ purchase intention of foreign products with respect to the types of postentry branding strategies. The study proposes that international marketers carefully seek out postentry branding strategies appropriate to the country-related product associations in order to yield positive outcomes in a host country market.
