급변하는 경제 환경 속에서 기업의 지속적인 성장(Scale-up)을 위해 기업가정신의 역할이 중요해지면서 많은 연구가 이루어지고 있다. 그간의 연구는 효율만을 강조하는 사업 중심의 성장을 주로 다루어 왔다. 그러나 최근 들어 기업 효율성 추구보다는 사람이 더 중요시되고 있는데 반해 사람중심의 기업가정신 특성에 대한 연구는 활발히 진행되지 못하였다. 특히, 중소기업을 대상으로 한 연구는 미비한 실정이다. 이에 본 연구에서는 사람중심 기업가정신 특성이 중소기업의 비지니스 생태계와 회사탁월성에 어떠한 영향을 미치는지, 비지니스 생태계와 회사탁월성은 기업성과에 어떤 영향을 주는지를 연구하는데 목적이 있다. 따라서 본 연구는 기업의 사람중심 기업가정신 특성을 공감, 역량개발, 권한위임, 업무몰입도로 구분하고 각각의 독립변수들이 매개변수인 비지니스 생태계와 화사탁월성에 미치는 영향과 비지니스 생태계와 회사탁월성이 경영성과에 미치는 영향을 살펴보는 인과관계 분석이 주된 연구대상이다. 연구의 결과를 자세히 제시하면 다음과 같다. 사람중심 기업가정신 특성과 비지니스 생태계 간의 인과관계에 대한 실증 연구결과를 요약하면 공감, 역량개발, 권한위임, 업무몰입도는 비지니스 생태계에 유의한 영향을 미치는 것으로 나타났다. 사람중심 기업가정신 특성과 회사탁월성 간의 인과관계에 대한 실증 연구결과를 요약하면 업무몰입도는 회사탁월성에 유의한 영향을 미치는 것으로 나타났으며, 공감, 역량개발, 권한위임은 통계적으로 회사탁월성에 유의한 영향을 미치지 않는 것으로 나타났다. 기업역량인 비지니스 생태계와 회사탁월성과 경영성과 간의 인과관계에 대한 실증 연구결과를 요약하면, 비지니스 생태계는 경영성과에 통계적으로 유의한 영향을 미치지 않는 것으로 나타났으며, 회사탁월성은 경영성과에 유의한 영향을 미치는 것으로 나타났다. 또한, 추가분석에서 사람중심 기업가정신이 회사탁월성을 거쳐 경영성과에 미치는 개별매개 효과는 통계적으로 유의한 효과를 가지는 것으로 나타났으며, 사람중심 기업가정신이 비지니스 생태계와 회사탁월성을 경유하여 경영성과에 미치는 개별매개효과가 나타났다. 이상의 연구결과와 함께 본 연구를 통해 다음과 같은 시사점을 제시할 수 있다. 첫째, 기존연구와 더불어 사람중심 기업가정신을 활용하여 중소기업을 대상으로 실증연구 했다는 점이다. 중소기업은 대기업이나 공공기관보다 사람중심 경영에 대한 인식이 낮을 것으로 추측되었으나 분석결과 사람중심 기업가정신이 비지니스 생태계에 큰 영향을 미치고 있음을 확인하였다는데 큰 의미가 있다고 하겠다. 둘째, 직렬 다중매개효과 분석의 연구결과는 기업에서 사람지향성의 분위기가 높을수록 기업가 지향성의 분위기도 높아지는 경향이 있으며, 사람중심 기업가정신이 경영성과에 미치는 영향에 있어 비지니스 생태계와 회사탁월성이라는 매개변수를 투입하여 매개효과를 검증함으로써 사람중심 기업가정신이 경영성과에 영향력을 미치는 경로를 확인하였다는 점이다. 마지막으로 우리나라 중소기업에 대한 사람중심 기업가정신에 대한 연구가 활성화되어 중소기업의 사업모델이 혁신형으로 전환하는데 이론적 기반을 제공할 수 있기를 기대해 본다.

Apoptosis signal-regulating kinase 1 (ASK1), a mitogen- activated protein kinase kinase kinase, plays pivotal roles in stress responses. In addition, ASK1 has emerged as a key regulator of immune responses elicited by pathogen-associated molecular patterns (PAMPs) and endogenous danger signals. Recent studies have demonstrated that reactive oxygen species (ROS)-dependent activation of ASK1 is required for LPS-stimulated cytokine production as well as extracellular ATP-induced apoptosis in immune cells. The mechanism of ROS-dependent regulation of ASK1 activity by thioredoxin and TRAFs has been well characterized. In this review, we focus on the molecular details of the activation of ASK1 and its involvement in innate immunity.

The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized an international session as part of the official program of the 72nd Annual Meeting of the Japanese Cancer Association to discuss the topic "What is cost-effectiveness in cancer treatment?" Healthcare economics are an international concern and a key issue for the UICC. The presenters and participants discussed the question of how limited medical resources can be best used to support life, which is a question that applies to both developing and industrialized countries, given that cancer treatment is putting medical systems under increasing strain. The emergence of advanced yet hugely expensive drugs has prompted discussion on methodologies for Health Technology Assessment (HTA) that seek to quantify cost and effect. The session benefited from the participation of various stakeholders, including representatives of industry, government and academia and three speakers from the Republic of Korea, an Asian country where discussion on HTA methodologies is already advanced. In addition, the session was joined by a representative of National Institute for Health and Care Excellence (NICE) of the United Kingdom, which has pioneered the concept of cost-effectiveness in a medical context. The aim of the session was to advance and deepen understanding of the issue of cost-effectiveness as viewed from medical care systems in different regions.

The disconfirmation paradigm is the earliest researched and the most deeply researched of all the paradigms in marketing. Disconfirmation paradigm deals with the influence of expectation, perceived product performance, and the discord between the two on consumer satisfaction. The GAP-Model is based on the disconfirmation paradigm that tries to understand the effect of the gap between before purchase expectations and after purchase perceptions of the product performance on dependent variables such as customer satisfaction. The purpose of this research is to test whether regression coefficients of a P-Model(performance only model), an E-Model(expectation only model) and GAP(P-E)-Model are equivalent in explaining service value and loyalty. The Chow's F-Test is used to test the excellence of the 3 models. As a result of comparison and analysis, P-Model showed more excellence of service value and loyalty than E-Model or GAP-Model.

The concepts of new classes of mappings are introduced in the spaces which are more general space than the usual metric spaces. The existence and uniqueness of common fixed points and fixed point results are established in the setting of complete complex valued b-metric spaces. An illustration is given by establishing the existence of solution of periodic differential equations in the framework of a complete complex valued b-metric spaces.

The purpose of this research is to compare whether SERVQUAL or SERVPERV AL scale is more excellent when explaining customer satisfaction and repurchase intention. The value of R2 which shows explaining power is used to test the excellence of the scale. As a result of comparison and analysis, SERVPERV AL scale showed better explaining power of customer satisfaction and repurchase intention than SERVQUAL. This result is because SERVPERV AL scale predicates overall estimation on utility of product/service.

The purpose of this study was to explore an intrinsic concept of 'company innovativeness' based on qualitative data obtained from 54 practitioners with at least 5 year-experience in the industry. Data were analyzed based on the grounded theory and Nvivo 2.0 program. Based on results, seven theme were generated. Seven intrinsic theme include 5 intrinsic concepts such as learning orientation, excellence of human resource, treatment for employees, market orientation and work efficiency, and 2 performance concepts such as business performance and innovation performance. These diverse concepts were considered as an important guideline in judging whether a company is innovative or not. In addition, diverse programs were provided by companies for a purpose of enhancing company innovativeness. Based on results, a research model was suggested to be elaborated in future studies. Implications and suggestions were generated based on results.

An experimental method was suggested for obtaining fracture toughness ($K_{Ic}$) and the tensile strength (${\sigma}_t$) of chopped strand glass fiber reinforced polymer concretes (PC). Semi-circular bend (SCB) specimens subjected to three-point bending were used for conducting the experiments on the PC material. While the edge cracked SCB specimen could be used to evaluate fracture toughness, the tensile strength was obtained from the un-cracked SCB specimen. The experiments showed the practical applicability of both cracked and un-cracked SCB specimens for using as suitable techniques for measuring $K_{Ic}$ and ${\sigma}_t$ in polymer concretes. In comparison with the conventional rectangular bend beam specimen, the suggested SCB samples need significantly less material due to its smaller size. Furthermore, the average values of ${\sigma}_t$ and $K_{Ic}$ of tested PC were approximately 3.5 to 4.5 times the corresponding values obtained for conventional concrete showing the improved strength properties of PC relative to the conventional concretes.

The behavior of hydrogen species on the surface of the catalyst during the Lewis acid transformation to form Brønsted acid sites over the spherical silica-supported WO_x catalyst was investigated. To understand the structure-activity relationship of Lewis acid transformation and hydrogen bonding interactions, we explore the potential of using the in situ diffuse reflection infrared Fourier transform spectroscopy (DRIFTS) with adsorbed ammonia and hydrogen exposure. From the results of in situ DRIFTS measurements, Lewis acid sites on surface catalysts were transformed into new Brønsted acid sites upon hydrogen exposure. The adsorbed NH₃ on Lewis acid sites migrated to Brønsted acid sites forming NH⁴⁺. The results show that the dissociated H atoms present on the catalyst surface formed new Si-OH hydroxyl species - the new Brønsted acid site. Besides, the isolated Si-O-W species is the key towards H-bond and Si-OH formation. Additionally, the H atoms adsorbed surrounding the Si-O-W species of mono-oxo O=WO₄ and di-oxo (O=)₂WO₂ species, where the Si-O-W species are the main species presented on the Inc-SSP catalysts than that of the IWI-SSP catalysts.
