Purpose: The underdog effect refers to a positive attitude towards the underdog who lacks resources and opportunities but has passion and determination. Extensive research has been investigated how the underdog effect affects distributing consumer preference and purchase intention. The purpose of this study is to identify the theoretical basis on which the underdog effect is grounded by analysing the prior research in the underdog literature. Research design, data and methodology: This study organizes the literature on the underdog effect by analyzing a total of 33 journals published in the past 16 years. Constructs and variables were extracted from the selected articles through the content analysis on a systematic literature review. Results: This literature review reveals that identity theories served as an overarching theoretical lens when examining the underdog effect. Additionally, the underdog effect was rooted in theories of justice and equity to explain the relationship between underdog brand positioning and consumer preference. Conclusions: This paper paves the way for future research based on prior research and trend analysis of underdog brand positioning. This article also provides an insightful interpretation and synthesis of the theoretical underpinnings of the impact of underdog effects on consumers' overall brand evaluations.

사회적으로 큰 관심의 대상이 되고 있는 무선 인터넷은 유선 인터넷과 달리 기술 환경과 그 특성상 여러 가지 제약점들을 가지고 있다. 대역폭이 낮고, 접속이 빈번하게 끊기며, 단말기내의 컴퓨팅 파워가 낮고 화면이 작다. 또한 사용자의 이동성 문제와 네트워크 프로토콜, 보안등에서 아직 기술적으로 부족한 부분을 보이고 있다 그리고 급속도로 증가하는 수요에 따라 무선 인터넷 서버는 대용량 트래픽을 처리할 수 있는 확장성이 요구되어지고 있다. 이에 본 논문에서는 무선 인터넷 프록시 서버 클러스터를 사용하여 앞에서 언급된 무선 인터넷의 문제와 요구들을 캐싱(Caching), 압축(Distillation) 및 클러스터 (Clustering)를 통하여 해결하려고 한다. TranSend는 클러스터링 기반의 무선 인터넷 프록시 서버로 제안된 것이나 시스템적인(Systematic) 방법으로 확장성을 보장하지 못하고 불필요한 모듈간의 통신구조로 인해 복잡하다는 단점을 가진다. 기존 연구에서 시스템적인 방법으로 확장성을 보장하는 All-in-one 이라는 구조를 제안하였으나 이 역시 모듈간의 통신 구조가 복잡하고 캐시간 협동성이 없는 단점을 가진다. 이에 본 논문에서는 모듈간의 단순한 통신 구조와 캐시간 헙동성을 가지는 클러스터링 기반의 무선 인터넷 프록시 서버를 제안한다. 16대의 컴퓨터를 사용하여 실험을 수행하였고 실험 결과 TranSend 시스템과 All-in-one 시스템에 비해 각각 54.86$\%$, 4.70$\%$의 성능 향상을 보였다. 캐시서버간 데이타를 공유할 수 있기 때문에 제안된 구조에서는 캐시서버 수에 무관하게 캐시 메모리 전체 크기를 일정하게 할 수 장점을 가진다. 반면에 All-in-one에서는 각 캐시서버가 모든 캐시 데이타를 가져야 하므로 캐시 메모리 전체 크기가 캐시 서버 수에 비례하여 증가한다.

This paper demonstrates a systematic approach for the design of broadband, high efficiency, high power, Class-AB RF amplifiers with high gain flatness. It is usually difficult to simultaneously achieve a high gain flatness and high efficiency in a broadband RF power amplifier, especially in a high power design. As a result, the use of a computer-aided simulation is most often the best way to achieve these goals; however, an appropriate initial value and a systematic approach are necessary for the simulation results to rapidly converge. These objectives can be accomplished with a minimum of trial and error through the following techniques. First, signal gain variations are reduced over a wide bandwidth using a proper pre-matching network. Then, the source and load impedances are satisfactorily obtained from small-signal and load-pull simulations, respectively. Finally, two high-order Chebyshev low-pass filters are employed to provide optimum input and output impedance matching networks over a bandwidth of 100 MHz-500 MHz. By using an EM simulation for the substrate, the simulation results were observed to be in close agreement with the measured results.

Purpose - The purpose of this study is to classify and analyze existing studies from various angles through systematic literature review of how human resources development has been researched in the domestic franchise business. These studies are intended to suggest the direction in which human resource development research should be conducted in the future in the franchise business. Research design, data, and methodology - This study is based on systematic literature review methodology. It has gone through the process of subject language setting, literature search routing, search term selection, literature selection, literature classification and literature analysis. The systematic literature review identified 59 peer-reviewed dissertations and scientific journal publications on the subject of HRD in Korea franchise business. Result - This study analyzed by research methods, research industries, research population and dependent variable using the systematic review process. The literature studied in the 2000s mainly led to research on education and training of franchise employees in beauty franchise business. In the literature studied since 2010, human resources development was mainly studied in the supervisor in the restaurant franchise business, and in the study of competence rather than education and training. According to the research methods, statistical methods were mostly relatively simple, such as t-test or one-way distribution analysis until the 2000s, and after 2010, in-depth and structural studies using multiple return analysis, structural method analysis, path analysis, multi-dimensional scale analysis, AHP, etc were conducted. When classified by study dependant, early research until the 2000s focused on the study of education and training, which is an independent variable, on the satisfaction of education programs, job satisfaction, and immersion. On the other hand, studies conducted since 2010 have produced more complex results using various medium variants, and those related to management performance and relationship performance have been mainly studied, rather than the satisfaction of the education itself. Conclusions - While the domestic franchise business is expanding in terms of quantity, such as the number of franchises and franchises, the development in terms of quality for the joint growth of franchises and franchisees is still lacking. In order for the franchisee to continue to grow with each other, the franchisee must identify and develop their current performance or expected capabilities through capacity modeling at various targets and levels.

We have inquired on what the statistical classes of the secondary schools had been aiming to, say the epistermlogical objects. And we now appreciate that the main obstacle to the systematic articulation is the lack of anticipation on what the statistical concepts are. This study focuses on the ingredients of the statistical concepts. Those are to be the ground of the systematic articulation of statistic courses, especially of the one for the school kids. Thus we required that those ingredients must satisfy the followings. i) directly related to the contents of statistics ii) psychologically developing iii) mutually exclusive each other as much as possible iv) exhaustive enough to cover all statistical concepts We examined what and how statisticians had been doing and the various previous views on these. After all we suggest the following three concepts are the core of conceptual developments of statistic, say the concept of distributions, the summarizing ability and the concept of samples. By the concepts of distributions we mean the frequency views on each random categories and that is developing from the count through the probability along ages. Summarizing ability is another important resources to embed his probe with the data set. It is not only viewed as a number but also to be anticipated as one reflecting a random phenomena. Inductive generalization is one of the most hazardous thing. Statistical induction is a scientific way of challenging this and this starts from distinguishing the chance with the inevitable consequences. One's inductive logic grows up along with one's deductive arguments, nevertheless they are different. The concept of samples reflects' one's view on the sample data and the way of compounding one's logic with the data within one's hypothesis. With these three in mind we observed Korean Statistic Curriculum from K to 12. Distributional concepts are dealt with throughout but not sequenced well. The way of summarization has been introduced in the 1 st, 5th, 7th and the 10th grade as a numerical value only. One activity on the concept of sample is given at the 6th grade. And it jumps into the statistical reasoning at the selective courses of ' Mathematics I ' or of ' Probability and Statistics ' in the grades of 11-12. We want to suggest further studies on the developing stages of these three conceptual features so as to obtain a firm basis of successive statistical articulation.

Purpose The healthcare services have drawn so much public attention, and many organizations such as schools and companies require the individuals to undergo the periodic health examination. In general, however, the mass health examination services are not managed in systematic way, and both examinees and medical staffs often experience much inconvenience while preparing, undergoing and managing the services. To address such problems, this paper aims to design the Health Examination Management System (HEMS), an integrated management system for mass health examination operations management, and implement its prototype. Design/methodology/approach First of all, HEMS enables the medical staffs to efficiently collect and manage the examination result data by supporting examination service management. Second, the users can efficiently analyze the cause-and-effect relationships among the examination items by using the visualization tool of HEMS based on the cluster heat map. Finally, the HEMS provides the operational supports for evaluating and managing the service performances. Findings The HEMS indicates that the conventional operations management approaches can be incorporated into the mass health examination services, and it is expected that the proposed system enables the examinees and the medical staffs to participate in such services in more efficient way.
