Companies must capture value for sustainable growth. Capturing value is a critical task for companies, particularly when operating own businesses and organizations or starting new business. The business strategy of many companies focuses on capturing the maximum value from customers and other stakeholders. Even though a wide range of studies on value creation and appropriation has been conducted in the strategic management field, most of studies are still conceptual and theoretical. Thus more empirical studies are required to suggest future-oriented value strategy. This study reveals the value creation and appropriation elements in the aviation industry of Korea. The purpose of this study is to understand the trend of value creation and appropriation in the industry. In addition, the relationship between the elements and firm's performance are tested. The firm's performance is defined by that past and future point of views. The sample were collected from Korean Air and Asiana Air. The empirical test shows that the elements of value creation-appropriation have significant impact on firm's performance. Further, the element of value appropriation to customer has a positive impact both on firm's past and future performance. Our results show that investors acknowledge a value-based strategy as a sign of stock valuation. The results of this test correspond with the earlier one, showing that maximizing customers value rather than shareholder value does deliver impressive returns. The finding suggest that companies need to change their strategy to efficiently manage performance. With the test results, we propose a value-based strategy to maximize firm's future financial and stock performance.

토공 자동화는 건설 산업에서 유망한 기술로 주목받고 있으며, 토공 자동화 기술의 적용은 건설 현장의 포인트 클라우드 데이터(Point Cloud Data, PCD) 취득 및 처리로부터 시작된다. PCD는 광범위한 건설 현장의 특성상 백만 개 이상의 많은 데이터를 가지며, 이에 대한 원데이터의 처리 속도는 디지털 지형 모델(Digital Terrain Model, DTM) 생성 및 공사의 효율성 증가에 매우 중요한 요소이다. 현재 국내 설계기준에 적합한 PCD 처리 및 BIM 설계 통합 프로그램인 벤치마크 프로그램(Benchmark Program, BP)이 존재하지만, 사용자의 편의성과 효율성을 위한 수정과 개선이 필요한 상황이다. 본 연구에서는 BP의 기존 PCD 처리 기능을 유지하며, PCD 파일의 호환성에 대한 확장 및 컴파일(Compile) 기반 개발 환경, OpenGL의 활용 및 UI/UX 디자인을 이용한 개선 프로그램을 개발하였다. 개발된 프로그램에 다양한 크기의 PCD를 로드 했을 때, 기존 프로그램과 비교하여 92~99%의 속도 향상이 있었다. 이 프로그램은 추후 PCD와 토공 BIM 기능을 통합하여 설계와 시공 사이의 간극을 줄이는 프로그램 개발의 기반이 될 수 있고, 나아가 토공 생산성 향상에 기여할 것으로 기대된다.

서비스 실패는 고객 충성도를 파괴시키는 잠재력을 가지고 있으므로 기업에서는 서비스 복구에 지대한 관심을 가지고 서비스의 질을 높이려고 노력하고 있다. 이러한 흐름에 따라 본 연구에서는 호텔이라는 특정 서비스 산업에서의 서비스실패와 복구전략에 대해 결정적 사건 기법을 이용하여 알아보았다. Hoffman et al.(1995)의 분류기법에 근거하여 416개의 자료가 분석을 위해 사용되었으며, 연구결과 업그레이드, 무료식사, 할인은 매우 효과적인 복구수단으로 나타났다. 일반적으로 무형적 복구보다는 유형적인 복구수단이 고객만족에 크게 영향을 주는 것으로 나타났다. 즉, 고객들은 보상에 근거한 복구형태를 더욱 선호하며 그들은 보상으로부터 보다 즉각적인 가치를 인식하는 것으로 보인다 하지만 무형적인 복구수단인 정중한 사과는 다른 세 가지의 유형적인 복구보다도 오히려 효과적인 것으로 나타났다. 또한 고객이 경험한 서비스실패의 심각성에 따라 그 고객의 재이용의도를 살펴본 결과, 심각성은 재이용의도에 부정적인 영향을 마치는 것으로 나타났다.

There has been an impetus in the development of biocontrol agents (BCAs) with the removal of a number of chemical compounds in the market, especially in the European Union. This has been a major driver in the development of Integrated Pest Management systems (IPM) for both pest and disease control. For control of mycotoxigenic fungi, there is interest in both control of colonization and more importantly toxin contamination of staple food commodities. Thus the relative inoculum potential of biocontrol agent vs the toxigenic specie sis important. The major bottlenecks in the production and development of formulations of biocontrol agents are the resilience of the strains, inoculum quality and formulation with effective field efficacy. It was recently been shown for mycotoxigenic fungi such as Aspergillus flavus, under extreme climate change conditions, growth is not affected although there may be a stimulation of aflatoxin production. Thus, the development of resilient biocontrol strains which can may have conserved control efficacy but have the necessary resilience becomes critical form a food security point of view. Indeed, under predicted climate change scenarios the diversity of pests and fungal diseases are expected to have profound impacts on food security. Thus, when examining the identification of potential biocontrol strains, production and formulation it is critical that the resilience to CC environmental factors are included and quantified. The problems in relation to the physiological competence and the relative humidity range over which efficacy can occur, especially pre-harvest may be increase under climate change conditions. We have examined the efficacy of atoxigenic strains of A. flavus and Clanostachys rosea and other candidates for control of A. flavus and aflatoxin contamination of maize, and for Fusarium verticillioides and fumonisin toxin control. We have also examined the potential use of fluidized-bed drying, nanoparticles/nanospheres and encapsulation approaches to enhance the potential for the production of resilient biocontrol formulations. The objective being the delivery of biocontrol efficacy under extreme interacting climatic conditions. The potential impact of climate change factors on the efficacy of biocontrol of fungal diseases and mycotoxins are discussed.

The purpose of this was to evaluate the in vitro effects of different application modes of tetracycline HCI on dentin root surfaces. The study group was comprised of 30 teeth with advanced periodontal disease extracted before the start of periodontal therapy. The diseased root surface was vigorously root planed to expose dentin. The teeth were sectioned and cotton pellets. soaked in a saturated solution of tetracycline HCI, were either "placed" or "burnished" on the prepared root surface for 3, 5 min. respectively. Control surfaces were similarly treated with root planing only. Following the various treatments, teeth were fixed. dehydrated, critical point dried, and coated for scanning electron microscopic(SEM) evaluation. The surfaces of tetracycline HCI treated specimens considerably differed from specimens treated with root planing only. Results demonstrated that root-planed, no-tetracycline HCI specimens had amorphous, irregular surface which corresponded to a smear layer. Tetracycline HCI specimens exhibited collagen fibers and dentinal tubules exposed by the removal of the smear layer. Although some differences were seen in surface structures among some specimens. "burnished" application causes more extensive change than "placed" application, and application time of the tetracycline HCl did not seem to have any major impact on the surface morphology.

Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

The objective of this study is to examine the effects of consumer beliefs regarding three food certifications on their behavioral intention and the behavioral intention biases to purchase (purchasing intention biases) certified agricultural products as predicted by a subjective probability model. The food certifications used for this study are 'Organic food', 'Traceability system of food products,' and 'Hazard Analysis Critical Control Point (HACCP)'. Tofu (bean curd) was selected as being representative of agricultural food products, for the purposes of this study. In 2016, we surveyed 243 consumers regarding the strength of their belief regarding their prior beliefs relative to each certification, as well as the strength of their intention to purchase certified tofu based on their belief strengths for this study. The study resulted in the following findings: Firstly, consumers hold more than two different prior beliefs for each of the three certifications included in this study. Consumers' prior beliefs regarding these certifications have an impact on their consideration as to whether they plan to buy those certified agricultural products. Secondly, consumers try to persuade themselves to ensure that their particular belief about the product's certification could lead to a purchasing decision regarding that agricultural product.
