Alliance formation has been recognized as an important strategy for firms who seek to survive through acquisition of sustainable competitive advantages. Specifically in high-tech industries, firms may consider formation of strategic alliances in order to access valuable external knowledge. These firms tend to be situated in a dilemma that they should choose between exploration and exploitation, which are two types of strategic choices suggested by March (1991). Working out the dilemma has been extensively discussed in the area of strategy or organization learning. Recently, however, an increasing number of studies have stressed on a balance between exploration and exploitation. Regarded as 'ambidextrous organizations' (Lavie and Rosenkopf, 2006), these firms that simultaneously pursue exploration and exploitation have emerged in high-tech industries, and many studies have provided evidence of positive association between organizational ambidexterity and firm performance. In the strategic alliance research, accordingly, scholars began to pay attention to the balanced choice between exploration-and exploitation-oriented alliances. Given these backgrounds, this study examines the relationship between alliance ambidexterity and firm performance. While previous research approached alliance ambidexterity mainly from the number of alliances, our study suggests ambidexterity in terms of alliance portfolio and alliance partner. Our dataset consists of biotechnology or pharmaceutical firms in the United States, which spans time period between 1990 and 2005. We conduct panel data analysis. The results show the strong link between alliance ambidexterity and firm performance, highlighting the balance between exploration and exploitation when firms make strategic decisions.

During the Japanese colonial period, Japan exploited the entire Korean Peninsula and targeted not only cities but also rural areas. The exploitation of rural area was accelerated with the support of Oriental colonization Company and The countryside was a living scene of direct exploitation. However, most of the research was concentrated in representative port cities such as Kunsan, which transports logistics such as rice and grains. There was insufficient research on how Japanese entered the country, how Korean were plundered, and the rural villages that were the target of exploitation. The contents of hi-exploitation were also historical and historical humanities such as colonial land ownership and farm management, and the spatial structure of the existing traditional villages were insufficiently investigated. Hwaho-ri, Shin Taein-eup, Jeollabuk-do, centered on Yongseo Village, there are many traces of farm houses, hospitals, employee residences, schools, churches, and Oriental colonization Company This study aims to study what changes traditional rural villages have brought by the Japanese colonial rule, centering on Hwaho-ri Village.

This paper examines the effect of innovation strategy and R&D organization on the innovation performances in the Korean small and medium sized enterprises(SMEs). For the SMEs with limited resources and capabilities, the one of key strategic issues is to allocate innovation resources to the exploitation of existing technological capabilities and/or the exploration of new technological capabilities. Based upon survey data from 769 SMEs, this study investigated relationships among exploitation and exploration strategies, the existence of R&D organization, and innovation performance. Exploration is positively related to product and process innovation performances across the industrial sectors. However, exploitation is positively related only to the process innovation performance in the traditional manufacturing sectors. The existence of R&D organizations has positive effects on the product innovation performance and not on the process innovation performance. Finally, it discusses the managerial implications, the limitations of this study and the future research directions.

Online technology markets are expected to provide technology suppliers with opportunities of external technology exploitation by reducing the transaction costs caused from technology transactions. This study empirically analyzes the characteristics of patents provided to the online technology market in order to identify the influences of the existence of online technology market on the patent exploitation strategy of technology suppliers. A sample of patent database is drawn from the National Technology Bank which was established as a public online market for technology. Main findings are that the propensity of patents offered to the online marketplace is higher in the cases where the patents are obsolescent, are non-core, and that consist of more claims and inventors. Through the findings of this study the existence of online technology market is identified to enable the external exploitation of firms" non-used technologies.

The purpose of this study is to examine the structural relationship between the digital platform capabilities of financial institutions and the impact of customer orientation on service innovation behavior through exploitation/exploration. A survey was conducted on employees of financial institutions to verify the research model, and the final 280 copies of the questionnaire were analyzed using SPSS 25 and SmartPLS 2.0. As a major research result, First, digital platform competency has a positive effect on exploitation and exploration. Second, customer orientation has a positive effect on exploitation, but not on exploration. Third, both exploitation and exploration have a positive impact on service innovation behavior. Through this research, this study shed new light on the relationship between digital platform capability and customer orientation that affects service innovation behavior of financial institutions, and expanded the scope of research through empirical research. Future research will require research attempts on various variables and research samples.

Shale gas formations exhibit strong mechanical and strength anisotropies. Thus, it is necessary to study the effect of anisotropy on the hydraulic fracture initiation pressure. The calculation model for the in-situ stress of the bedding formation is improved according to the effective stress theory. An analytical model of the stresses around wellbore in shale gas reservoirs, in consideration of stratum dip direction, dip angle, and in-situ stress azimuth, has been built. Besides, this work established a calculation model for the stress around the perforation holes. In combination with the tensile failure criterion, a prediction model for the hydraulic fracture initiation pressure in the shale gas reservoirs is put forward. The error between the prediction result and the measured value for the shale gas reservoir in the southern Sichuan Province is only 3.5%. Specifically, effects of factors including elasticity modulus, Poisson's ratio, in-situ stress ratio, tensile strength, perforation angle (the angle between perforation direction and the maximum principal stress) of anisotropic formations on hydraulic fracture initiation pressure have been investigated. The perforation angle has the largest effect on the fracture initiation pressure, followed by the in-situ stress ratio, ratio of tensile strength to pore pressure, and the anisotropy ratio of elasticity moduli as the last. The effect of the anisotropy ratio of the Poisson's ratio on the fracture initiation pressure can be ignored. This study provides a reference for the hydraulic fracturing design in shale gas wells.

A new evolution method for strong exploration and strong exploitation termed queen-bee and mutant-bee evolution is proposed based on the previous queen-bee evolution [1]. Even though the queen-bee evolution has shown very good performances, two parameters for strong mutation are added to the genetic algorithms. This makes the application of genetic algorithms with queen-bee evolution difficult because the values of the two parameters are empirically decided by a trial-and-error method without a systematic method. The queen-bee and mutant-bee evolution has no this problem because it does not need additional parameters for strong mutation. Experimental results with typical problems showed that the queen-bee and mutant-bee evolution produced nearly similar results to the best ones of queen-bee evolution even though it didn't need to select proper values of additional parameters.

Climate changes have impacted to many sectors including water resources in Vietnam. Vietnam is agricultural development country having a lot of reservoirs. These reservoirs play a very important role in flow regulation for water supply to economic sectors. In the context of undesirable impacts of climate change such as increasing temparature, evaporation, changing rainfall and rainfall pattern, water demands and inflow to reservoirs also are being influenced. This leads to changes of resevoir exploitation effects that needs to be assessed for adaptation solutions. This arcticle summaries the development of a tool for quick assessement of climate change impacts on exploitation effect of reservoir in central provinces of Vietnam.
