Background and objective: This study was conducted to investigate the effects and preferences of horticultural therapy programs for stress relief according to MBTI personality types (Judging and Perceiving types) of female undergraduate students. Methods: The participants were divided into 15 Judging and 15 Perceiving types based on lifestyle preferences of the MBTI personality test, and a total of 30 participants participated in the horticultural therapy programs for 6 sessions. Results: Both Judging and Perceiving types showed a significant decrease in stress after participating in the horticultural therapy programs. Among the 8 life stress subfactors, Judging types showed significant stress relieving effects in 5 subfactors (relationship with the opposite sex, relationship with family, economic problems, future problems, value problems), while Perceiving types showed stress relieving effects in only 3 subfactors (relationship with family, economic problems, future problems). However, the changes in stress relief of 8 subfactors were not significantly different between the two personality types. The most preferred program for the Judging types was 'Making a flower basket', while the most preferred ones for the Perceiving types were 'Planting monstera', and 'Making preserved lemons with marigold', suggesting that the preferences varied depending on personality types. Conclusion: Therefore, it is necessary to develop suitable horticultural therapy programs for different subjects based on their personality types to enhance the effect of the programs on the subjects.

Despite the growing emphasis on the importance of knowledge exchange among supply chain participants, few companies have fully exploited the knowledge resources held by their supply chain partners. Among many reasons for this phenomenon, recent literature on inter-firm knowledge exchange identifies knowledge complementarities between the supply channel partners as an important determinant of knowledge exchange. Firms participating in a supply chain are likely to exchange partners' complementary knowledge. In order to extract value from them, it is important to recognize the difference between the potential value and the implementation of this potential value. However, the literature fails to distinguish between potential knowledge complementarities and implemented knowledge complementarities. In order to realize the value of potential knowledge complementarities, knowledge should be exchanged and effectively integrated in the supply channel. Further, investigating inter-firm knowledge exchange from both partners' perspectives is important especially when there are interdependencies between the channel partners. The purpose of this research is to investigate the impact of potential knowledge complementarities on knowledge exchange in buyer-supplier relationships by looking at both partners' perspectives. This research also includes trust in partner's competence and inter-organizational information systems (IOIS) as they are relevant when the complementary knowledge flows between organizations. The data required for this field study was collected from 70 buyers and their suppliers in three multinational enterprises in two different industries (Automobile manufacturing and Telecommunication services) headquartered in Korea. The results indicate that potential knowledge complementarities between buyer and supplier do not directly influence knowledge exchange, but indirectly through trust in partner's competence. And the results indicate that competence-based trust and IOIS have direct effects on knowledge exchange. Empirical results also show that IOIS moderates the relationship between potential knowledge complementarities and knowledge exchange. This study is a first attempt to empirically verify the theoretical model about potential knowledge complementarities and to investigate the impact of potential knowledge complementarities on interfirm knowledge exchange. From a theoretical perspective, this study not only clarifies the distinction between potential knowledge complementarities and implemented knowledge complementarities, but also develops an instrument to measure the concept of potential knowledge complementarities in the context of operational and planning knowledge in a supply chain. Further, we develop a theoretical framework suggesting that potential knowledge complementarities of partners in a supply chain affect knowledge exchange directly and indirectly through competence-based trust. The findings from this study have some managerial implications for practicing managers as well. First, buyers should search for suppliers that have potential complementary knowledge, which can be integrated to create synergy through interfirm knowledge exchange. Furthermore, firms must develop mechanisms to identify potential complementary knowledge of partners. Second, firms should continue their endeavor to develop their own unique knowledge so that their knowledge can benefit the entire supply channel. Finally, trust among supply chain partners turns out to be an important factor for interfirm knowledge exchange. Therefore, effective management for engendering trustworthy buyer-supplier relationships should receive appropriate attention from managers.

This study started from the need to change the technocentric view of environment into the ecocentric one to overcome ecological crisis today. Thus, the purposes of this study are to reorganize characteristics of ecocentrism, to analyze ecocentrism of Native North Americans as a realistic model, and to finally find suggestions to environmental education. The results of this study can be summarized as follows; Frist, the ecocentric perception on relationship between human beings and nature pursues co-existence through harmony and balance based on holistic understandings. And the ecocentric perception on relationship among human beings attempts to preserve environment by overcoming rule structure among them. The ecocentric perception on relationship between human beings and spirituality is to set life goals to achieve spirituality rather than to pursue material life. Second, Native North Americans have a holistic world view that human beings and nature are an inseparable one through the symbol of 'the Sacred Circle'. They also lived simple lives which satisfies vital needs instead of pursuing material lives in terms of the perception on relationship among human beings. When it comes to the perception on relationship between human beings and spirituality, they feel sacredness from all things in daily life and want to have peaceful relationships with their own inside through spirituality toward 'Mother Earth'. Third, the ecocentrism of Native North Americans make suggestions that environmental education confirm again what roles of human beings are in ecosystem, and that it helps students develop ecological sensitivity by giving them many opportunities to go to field trips. Furthermore, environmental education helps them positively think about and actively choose simple life. In addition, it has to be designed to help students seek sacredness in daily life through ecological imagination. This study has values of newly organizing characteristics of each ecocentric idea by integrating it from complementary aspects, and pursuing direction of ecocentrism and its realistic possibility by analyzing the ecocentrism of Native North Americans as a model of ecological life.

Purpose - This paper aims to investigate whether information asymmetry could explain capital structures in Korean corporations. According to Myers (1984), firms prefer internal funding to external financing due to the costs associated with information asymmetry. When external financing is necessary, firms prefer to issue debt rather than equity by the same reasoning. Since Shyam-Sunder and Myers (1999), numerous studies continue to debate the validity of the theory. In this paper, we show how the theory depends on assumptions and incorporated variables. We hope our investigation can provide helpful implications regarding capital structure, information asymmetry, and other firm characteristics. Specifically, our empirical results are complementary to the analysis of Son and Lee's (2015), a recent study that examines the pecking order theory prediction for Korean retail firms. Research design, data, and methodology - We test empirical models that are some variants of model used in Shyam-Sunder and Myers (1999). The financial and accounting data are provided by WISEfn for the firms listed on the KOSPI during 1990 to 2013. Bond ratings are supplied by the Korea Investor Service (KIS). We take into account the heterogeneity in debt capacity; a firm's debt capacity is measured by using the method of Lemmon and Zender (2010) based on its bond ratings. Finally, we estimate empirical models suggested by Shyam-Sunder and Myers (1999), Frank and Goyal (2003), and Lemmon and Zender (2010). Results - First, we find that Shyam-Sunder and Myers' (1999) prediction fails to explain total debt changes of Korean firms. Second, we find a non-monotonic relationship between total debt changes and financial deficits with respect to debt capacity. This contradicts the prediction of Lemmon and Zender (2010) that argues the pecking order theory survives with a monotonically increasing relationship. Third, we estimate a negative correlation coefficient between financial deficit and current debt changes. The result is the complete opposite of the prediction of Lemmon and Zender (2010). Finally, we also confirm the non-monotonic relationship between non-current debt changes and financial deficits with respect to debt capacity. Yet, the slope of coefficient is smaller than that of total debt change case. Indeed, the results are, to some extent, consistent with the prediction of pecking order theory, if we exclude the mid-debt capacity firms. Conclusions - Our empirical results complementary to the analysis of Son and Lee (2015), a recent study focusing on capital structure in Korean retail firms; their paper suggests interesting topics regarding capital structure, information asymmetry, and other firm characteristics in Korean corporations. Contrary to Son and Lee (2015), our results show that total debt changes and current debt changes are inconsistent with the prediction of Shyam-Sunder and Myers (1999). However, similar to Son and Lee (2015), non-current debt changes are consistent with the pecking order prediction, in the case of excluding the mid-level debt capacity firms. This contrast allows us to infer that industry characteristics significantly affect the validity of the pecking order prediction. Further studies are needed to analyze the economics behind this phenomenon, which is beyond the scope of our paper. In addition, the estimation bias potentially matters regarding the firm-level debt capacity calculation. We also reserve this topic for future research.

Increasingly the information technology (IT) outsourcing phenomenon has been a subject of much academic research. Scholars have argued that knowledge complementarities playa crucial role in forming successful IT outsourcing relationships. However, notwithstanding the fast growth of IT outsourcing, prior studies on IT outsourcing have not included knowledge complementarities in their research design as a determining factor for IT outsourcing effectiveness. Further, the understanding of knowledge complementarities itself remains ambiguous. In this study, the concept of knowledge complementarities is explored in the IT outsourcing context at the firm level. Specifically, it addresses the following questions: what is knowledge complementarities? How does it affect IT outsourcing effectiveness? Is the relationship between knowledge complementarities and IT outsourcing effectiveness influenced by organizational trust between the client and the vendor? Grounded in the relevant theories to knowledge management and IT outsourcing, we develop a research model in which both the main effects of knowledge complementarities and organizational trust and the moderating effect of organizational trust on the relationships between knowledge complementarities and IT outsourcing effectiveness are tested. Within this research model, we develop a second order construct of knowledge complementarities, consisting of complementary business knowledge and complementary IT knowledge as the first order constructs. We have used data from a field study of 103 firms in Korea to test the proposed model. Controlling the effects of conflict resolution efforts, our empirical analysis found significant main effects of knowledge complementarities and organizational trust on IT outsourcing effectiveness. The results suggest that knowledge complementarities between the client and vendor positively contribute to IT outsourcing effectiveness. Specifically, the client needs to have enough IT knowledge to assess the quality of IT outsourcing services provided by the vendor. Meanwhile, the vendor should understand the client's business well enough to provide IT services, Contrary to our expectations, the moderating effect of trust on the relationship between knowledge complementarities and IT outsourcing effectiveness was not supported in this study. The results also show that organizational trust between client and vendor significantly influences IT outsourcing effectiveness. As for contributions of this study, we have not only clarified the concept of knowledge complementarities, but also developed an instrument to measure the concept and empirically validated it. Further, we have tested the idea that knowledge complementarities and trust directly influence IT outsourcing effectiveness and trust moderates the relationship between knowledge complementarities and IT outsourcing effectiveness. Out results prescribe the knowledge complementarities of client and vendor as a useful path to IT outsourcing effectiveness. These findings have important theoretical and practical implications, which are discussed in the paper.

This paper empirically examines the relationship between a firm's external technology acquisition and in-house R&D in Korean manufacturing sectors. Using the technology innovation survey conducted by the Korean government in 2002, and developing a semi-structural empirical model, we find that the firm's in-house R&D and technology acquisition have a complementary relationship: A firm's technology acquisition increases in its in-house R&D. Moreover, government R&D funding and tax incentives have positive effects on the in-house R&D, while the existence of the failed projects encourage a firm to acquire more external technologies.

Purpose - This research focuses on the analysis of logistics barriers in Korea, China and Japan facing the barriers of overseas-expanded manufacturers with other countries. With the tree countries are emerging as the biggest trade partners in Northeast Asia, their logistics barriers are applied with similar verification methods of preceding researches such as Carter(1997). Research design, data and methodology - Collecting the statistics data from the three countries' overseas-expanded manufacturers, t-verification was performed in order to analyze average value and verify any significance. Additionally, multiple regression analysis was used to analyze any influence on the relationship in Korean logistics barrier and Chinese and Japanese expansion to Korean market. Results - Statistics suggested that three countries' logistics barriers are significantly differentiated by each verification categories, and Korean barrier negatively affected Chinese and Japanese manufacturers coming into Korean market. Conclusions - As a result of multiple regression analysis of the influencing relationship between Korea's logistics barrier and Chinese and Japanese companies coming into Korean market, all of the Korean barriers are affecting the companies as an obstructive factor, and it is proved to be statistically meaningful. Therefore, in order to reduce Chinese and Japanese companies' cost burden, it is necessary that not only reasonable charge system and taxation support but also comprehensive measure establishment reduce Korea's logistics barriers. However, since this research has a limitation in samples and shows a period of 5 years in the three nations' trade barriers, continuous and complementary researches are necessary in order to develop certain objectivity.

The slotted plate technique has previously been shown to be a successful method for directly measuring the static yield stress of suspensions. In this study, we further establish the usefulness of the slotted plate device as a rheometer especially at low shear rates, taking advantage of the extremely low speeds of the slotted plate technique. Newtonian fluids, a shear thinning fluid, and yield stress fluids were tested using the slotted plate device and the results were compared with those from a commercial rheometer using different standard flow geometries. The relationship between the stress on the plate and the viscosity for the slotted plate device obtained by dimensional analysis (drag) predicts a linear relationship between the force at the plate and the plate speed, consistent with the experimental data. The slotted plate device can measure viscosities at very low shear rates. The apparent viscosity - shear-rate data obtained from the slotted plate device are complementary to those obtained using a commercial rheometer. That is : the slotted plate can measure viscosity in the shear rate range $10^{-7}<\dot{\gamma}<10^{-3}\;s^{-1}$, while the commercial rheometer measures viscosity at shear rates higher than $10^{-3}\;s^{-1}$.

We investigate the God gate olleh of the largest tomb, pyramid, in the world which is scattered in Jeju Island and construct link which is connecting Jeju people's custom to modern science. The three sacred gates and the two tombs are connected to the olegil space. In this space, the principle of complementarity in which coexistence exist between life and death is hidden in Jeju culture. It is a question and wait. Contrarily, the opposite is complementary. (Contraria Sunt Complementa Latin) This refers to the relationship of each other in relation to one another and in a mutually dependent relationship. Seminal vesicles are used as basic logic in DNA codon of human body as well as communication principle.
