Reverse knowledge transfer has been an important research theme in the literature on multinational corporations (MNCs). This paper proposes major determinants of MNC headquarters' willingness to adopt and use marketing knowledge from their subsidiaries. We argue that the willingness will be jointly determined by both the headquarter's absorptive capacity and the focal subsidiary's transfer capacity and willingness to transfer. In addition, we argue that these capability and motivation effects are moderated by (1) institutional distance between home and the focal host country, (2) the need to unlearn existing routines, and (3) types of entry modes. This paper contributes to the reverse knowledge transfer literature by proposing the argument that both motivational and capability factors are likely to determine the MNC parents' willingness to adopt and use marketing knowledge from their subsidiaries.

The purpose of this study is to classify the types of local market knowledge and knowledge sources in reverse knowledge transfer and analyze their relevance. To do so, first, we searched for papers related to the types of local knowledge published in 9 international business academic journals between 1988 and 2020, and derived four types of local market knowledge. Second, in order to classify the source of knowledge, we searched for papers related to network types published in 9 international business academic journals between 1988 and 2020, and divided them into 4 types to derive characteristics. Third, by examining the types of local market knowledge that can be obtained according to network types, a conceptual model was developed between them, and the suitability between local market knowledge and sources of knowledge was revealed through empirical analysis. Through empirical research on what kind of knowledge can be obtained depending on the knowledge sources, various business and academic implications can be provided to many companies.

최근 해외자회사로부터 본사로 행해지는 역지식이전에 대한 실증적 관심이 크게 증가하였다. 하지만 동 현상에 영향을 미치는 주요 요소들에 대한 논쟁은 아직 일반적인 합의를 이루지 못했다. 이에 따라 본 연구는 현지 시장 정보를 본사에 역지식이전 하는데 있어 자회사가 보유하고 있는 지식이전능력이 갖는 효과에 대해 알아보고자 하였다. 그렇게 하는 과정 속에서, 또한 외재적 지식이전능력과 역지식이전 간 관계에 시현하는 내재적(즉, 본질적인) 지식이전능력의 조절효과를 살펴보고자 시도하였다. 한국에서 수집된 데이터를 통해, 본 연구는 지식개발능력과 자회사의(지식이전) 의지가 본사로의 성공적인 역지식이전에 결정적인 역할을 수행함을 발견하였다. 더욱이 자회사의 의지는 지식개발능력과 역지식이전의 관계에 중요한 조절효과를 가짐을 실증하였다. 이러한 결과들을 바탕으로, 본 연구는 이론적 기여 및 실용적 시사점을 제공하고자 노력하였다.

In-depth knowledge of fabric microstructure is essential for understanding clothing comfort since it plays a significant role in heat and mass transfer between the human body and clothing. In this study, a novel method was employed for investigating 3D surfaces and solid construction characteristics of specific fabrics by using a reverse engineering technique. The surface construction data were obtained by a confocal laser scanning microscope and then manipulated by a 3D analysis program. Triangle mesh was used for connecting each 3D point, with clouds and fabric surface characteristics created by rendering techniques. For generating a 3D solid model, determinants of radius of curvature was used. According to the proposed method, actual surface expression of the real fabric was achieved successfully. The results from this methodology can be applied to the detailed analysis of clothing comfort that is highly influenced by the microstructure of the fabric.

Purpose Targeting Korean companies listed on Korean securities markets (i.e., KOSPI and KOSDAQ markets), this study aims to shed lights the effects of personal information security breaches on stock prices of information security companies. Interestingly, this study is, to the best of our knowledge, the first to examine the information transfer effect on personal information security breaches of companies. Design / Methodology /Approach To examine the information transfer effect of personal information security breaches, our study employs the event study commonly used in financial studies. To this end, we investigate a variety of events of personal information security breaches of companies listed on the KOPSI stock market and the KOSDAQ market. We collect the total samples of one hundred and twelve with forty seven of events of personal information security breaches by thirty companies and sixty five of information security companies. Findings The principal findings from the empirical study are as follows. First, for companies of personal information security breaches, our event study presents the significantly negative AAR (averaged abnormal return) value on the event day at the 5 % level and the highly significant negative CAAR(cumulative averaged abnormal return) value on the event day and the day after the event day at the 1 % level. The results suggest that personal information breaches significantly contribute to an decrease in value of the information breached companies. The cross sectional regressions in this study estimate the significantly negative coefficient for the ME/BE variable, the proxy for a growth opportunity at the 5 % level. This suggests a reverse relation between the growth opportunity of companies and their value. As for the various samples of the information security companies categorized by physical security, network and system security, security application software, code authentication, system integration, we find the significantly positive AAR on the day after the event day at the 5% level, only for the network and system security-companies. This addresses that the information transfer effect followed by personal information breaches is uniquely observable for companies categorized into network and system companies. The regressions for the network and system companies estimate the significantly positive coefficient for the NS dummy variable (i.e., the dummy of the network and system security companies) at the standard level. This allows us to identify appropriate times needed to make the information transfer effect realized from personal information breached companies to information security companies.

표준 전해액에 2중량%의 VC(vinylene carbonate)와 FEC(fluoroethylene carbonate)를 각각 첨가한 전해액으로부터 흑연 음극 표면에 SEI(solid electrolyte interphase) 층을 형성시키고, SEI 특성에 따른 흑연 음극의 저온($-30^{\circ}C$) 충방전 특성을 조사하였다. 흑연의 충 방전 용량은 FEC를 첨가한 전해액, 표준 전해액, 그리고 VC를 첨가한 전해액의 순서로 감소하였고, 충 방시 발생하는 과전압은 반대경향을 보이며 증가하였다. 이는 첨가제의 종류에 따라 생성된 SEI 층의 저항과 전하전달저항에 차이가 있음을 설명하는데, 이를 SEI 층의 화학 조성과 두께를 비교하여 확인하였다. 표준 전해액으로부터 생성된 SEI 층은 C-O 성분을 포함하는 고분자 형태의 화합물과 리튬 염의 환원분해로 생성된 $Li_xPF_yO_z$ 등으로 구성되었다. VC를 포함한 전해액으로부터 생성된 SEI 층은 C-O 화합물 비율이 높고 조밀하여 리튬 염의 분해가 억제되어 얇은 피막이 생성됨에도 불구하고 가장 큰 저항 값을 보였다. 반면에 FEC로부터 생성된 SEI 층은 C-O 성분의 비율이 VC를 첨가한 전해액의 경우보다는 작으면서도 리튬 염의 분해가 크지 않아서, 리튬 이온의 이동이 가장 용이한 피막을 형성하고 있어 가장 낮은 피막저항 및 전하전달 저항을 나타내었다. 결론적으로 FEC를 첨가제로 사용한 경우 생성된 SEI 층의 저항이 가장 작아서 흑연 음극의 저온특성이 가장 우수하였다.
