      • An empirical analysis of the repeated web site usage based on expectation-disconfirmation theory

        구철모 Graduate School of Sogang University 2002 국내박사

        RANK : 1839

        Customers' evaluation of Web Site in terms of satisfaction is critical in electronic commerce. Previous researches have studied in a distinct approach; especially IT oriented constructs- perceived usefulness, perceived easy of use and marketing oriented constructs-product, shopping experience, service quality. Even though the previous studies have studied regarding the usage and the purchase of goods and services, there was few exactly explanation how consumers formed satisfaction, why they leave Web site without purchasing. This study explores those determinants of consumer satisfaction and consequences with Web Site using expectation-disconfirmation theory (EDT). The present paper extends the range of EDT from the antecedents of expectation to the consequences of satisfaction. The disconfirmation paradigm hypotheses are generally supported by the analysis. These hypotheses are central to the purpose of this study, and they are demonstrated the consistency of the disconfirmation paradigm with the perceptions and feelings reported by respondents. Thus, this paradigm provides a useful framework for Web Site repeated usage based on expectation-disconfirmation theory. The framework also involves experience and familiarity into EDT framework. The experience and familiarity variables suggest that they can help to form expectation as well as influence satisfaction. Second, higher expectation makes a negative impact on disconfirmation of expectation. Third, a positive disconfirmation of expectation makes a positive impact on satisfaction. Forth, a perceived performance influenced by experience and expectation has an impact on satisfaction, and satisfaction produces repurchasing intention. Finally, a loyal customer has stronger intention to repurchase than a satisfied customer. This study takes a step toward resolving that the evaluation is consumers are using the result of a comparison process by the initial expectation and post experience. Experience based norms and knowledge based familiarity concept appears to offer an alternative for examining how consumers form disconfirmation beliefs and satisfaction feelings.

        ABSTRACT A thesis submitted to the committee of Graduate School, KongJu National University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Conferred in February 2020. A Proposal for Improving Effectiveness of Disaster Impact Assessment system Cheol-Mo SEO Department of Construction and Environment Engineering Graduate School of Kongju National University Gong Ju, Korea (Supervised by Professor Sung-Gil KIM) The Disaster Impact Assessment System(DIAS) is a system that, prior to the decision of various development plans or businesses, predicts the change of natural conditions caused by various developments and prevents possible various disasters. This paper viewed DIAS as a social regulatory policy through literature investigation, case analysis and survey. Also this paper analyzed problems and presented improvement plans. First, the DIAS means a social regulatory policy, protects citizens’s safety and has a characteristic of outcome regulation. Its basis is on Article 34 and 122 of the Constitution. Second, through a comparative analysis of Environmental Impact Assessment and Traffic Impact Assessment, this study induced the reason of excluding national administrative plans, the introduction of PQ system, securing the professionalism of manpower in charge, separate service purchase, separation of conference organ from approval agency, making of integrated management system and the necessity of follow-up coordination processes. In case of the United States, Japan and Canada, the DIAS is included in the Environmental Impact Assessment System(EIAS). On the other hand, however, our country is operating the DIAS as a separate system due to frequent disasters and their massive impact on the society. This paper through the comparison and analysis with those countries, studied measures of improving the DIAS such as the assessment of broad government behaviors, wide application of scoping system, aggressive control of environment impact assessment reports and continuous updating of guideline. Third, this study, by reviewing actual cases applied by the DIAS, drew problems definitely; in short, it figured out many problems such as lack of professionalism of public servants in charge and deliberation committee, low level of evaluation sheet and lack of consistency in planning and implementation. Fourth, through a survey of public servants in charge and the persons concerned, it was possible to find out their awareness of the DIAS and identify the effectiveness of their improvement plans. Improvement plans include the presentation of definite guideline to upgrade their professionalism, expansion of staff dedicated to the DIAS, expansion of education and consulting, the readjustment of service charge and the settlement of PQ system. Fifth, this study presented problems and improvement plans of the DIAS: preview stage; consultation stage; and implementation stage. In the preview stage, the study explained the introduction of Scoping system (revision of law, Separate Purchase method of the services(revision of enforcement ordinance), PQ system, Total management by basin unit(revision of enforcement regulation), Readjusting administrative plans and a guideline classification (revision of guideline), Countermeasures to secure the professionalism of local government servants(besides). In the consultation stage, this paper suggested an Integrated Management System to check implementation and the necessity of separation of local government’s approval and discussion(revision of enforcement ordinance), the necessity of committee meeting to be held by convene and an adjustment application of committee decision(revision of enforcement regulation), an offer case study opportunity and measures to enhance their ability(besides). In the checking stage on the implementation, this study presented the following measures: the database on the effectiveness of settling basin and retention basin, strengthen the penalty(revision of law), the standardization of management log and compulsory report to committee of conditional agreement(revision of enforcement regulation), drawing up manuals for self-checking(revision of guideline), utilization plans of those who complete educational programs and management controller and professionals(besides).

        The future combat system requires a various of weather conditions and full range operational capability. In order to achieve this aim, it has to hold an intergrated function by precision launch capability, mobility security made by light-platform, direct fire gun and artillery. In particular, an increase of fire power is one of very important purposes . a recoil force rise due to increase of fire power is inevitable. It has been studying the recoil force reduction method in order to elevate fire power in western countries. In conventional recoil, it is very restrictive that recoil force reduction method for increase of fire power. there is an increase of recoil distance and an optimized orifice design, etc but limited. so recoil concept is introduced that a recoil force is offset momentum occurred by accelerating recoil parts forward. a conventional recoil is the third step such as firing, recoil, recuperation but a recoil concept by exchanging momentum is the fourth step such as forward acceleration, firing, recoil, recuperation. At the beginning in the recoil system by exchanging momentum, Recoil parts are recoiling from regular intervals and when momentum occurred by accelerating recoil parts forward reaches appropriate level, it is the command to fire. After the propellant ignition, Recoil force and forward momentum is offset, and it is recoiled by remaining recoil force and recuperated to initial position. In this study, it is induced motion equation by exchanging momentum in recoil system and using AMESim model and the variables that affect forward momentum were studied. The AMESim modeling were verified by comparing test results and analysis. When fire tests, recoil force and recoil distance with and without forward momentum were compared with each other.

      • 한국 ‘복지정치’에서의 정당의 역할에 관한 연구 : ‘주체세력 형성’ 을 중심으로

        철모 경남대학교 행정대학원 2014 국내석사

        RANK : 1311

        본 연구는 오늘날 사회복지가 정치현장에서 이슈가 된 원인은 무엇일까? 하는 의문에서 출발하여, 주체세력의 형성을 중심으로 한국 사회복지정책의 전개과정을 비판적으로 고찰하고, 한국 내 주요 정당들의 강령과 18대 대선공약 분석을 통하여 한국 ‘복지정치’에서의 정당의 역할을 살펴보았다. 주요 연구결과는 다음과 같다. 한국 사회복지정책의 전개과정을 주체세력의 형성을 중심으로 살펴보면 시기별 특성에 따라 세 가지 시기로 나눌 수 있다. 첫 번째 시기는 사회복지 ‘주체세력 형성의 맹아기’로서 해방부터 1987년 6월항쟁 이전까지로 사회복지를 주창할 어떠한 세력도 형성되지 못하였지만, 경제성장과 더불어 노동자계급이 형성되기 시작한 시기이다. 두 번째 시기는 사회복지 ‘주체세력의 형성기’로서 1987년 6월항쟁 이후부터 1997년 문민정부까지로 87년 6월항쟁 이후 권위주의체제에서 민주주의체제에로 정치체제가 변화하고 1995년 전국적 연대조직인 민주노총이 결성되어 사회복지 주체세력으로서의 역할을 하기 시작한 시기이다. 세 번째 시기는 사회복지 ‘주체세력 형성의 발전기’로서 외환위기 이후부터 2012년 이명박 정부까지의 시기로 한국사회가 노동자세력과 정당과의 연대를 통해 복지국가로서 갖추어야 할 기본적인 기틀을 갖추게 되었으며, 진보정당의 출현으로 정당에 의한 복지정치가 활성화되면서 한국사회에 복지담론의 보편화를 가져온 시기이다. 이러한 사회복지정책의 전개과정에서 주목할 점은 주체세력으로서 노동세력의 전국적 연대조직인 민주노총이 결성된 이후에 사회복지정책이 비약적으로 발전하였고, 복지정치의 장에 정당이 등장함으로써 한국사회 복지담론의 보편화가 이루어졌다는 것이다. 또한, 사회복지정책 발전의 주체세력으로서 정당의 등장은 한국사회의 복지국가 건설의 속도를 빠르게 가속화시키고 있다는 것이다. 즉, 한국 내 주요 정당들은 복지정책의 확대를 주장하고 있으며, 특히 그 정책들은 보편주의가 확대되는 방향으로 수렴되고 있었다. 그러나 보편적 복지국가 건설을 위한 전제조건과 각 정당의 정치?경제적 지향이 담긴 복지국가 구상이 일치하지 않고, 또 각 정당들 간의 복지국가 구상에 편차가 존재한다는 점을 감안하면, 한국사회의 복지국가 건설 과정이 그렇게 순탄치만은 않다는 것을 엿볼 수 있을 것이다. 따라서 한국사회가 처한 조건과 실정에 맞는 한국형 복지모형을 만들기 위한 논의와 토론은 금후 더욱 활발히 이루어져야 하며, 각 정당들의 복지구상 차이를 극복하고 보편적 복지국가를 건설하기 위해서는 주체세력의 역할, 특히 노동세력과 정당과의 연대가 무엇보다 시급히 요구된다고 하겠다. This study started from the question 'What cause made today social welfare become an issue in political field?' and investigated the development process of Korean social welfare policies around the main group formation and analyzed the major parties' doctrines and 18th presidential election pledges in order to find out the what roles a political party as a main group in the welfare politics take in the process developing social welfare policies. Looking around the main groups' formation in the development process of Korean social welfare policies, there can be divided into 3 periods according to each period's characteristics. First period was the 'Sprout Period of Main Group Formation' for social welfare ranging from Korean Liberation to before June Struggle in 1987. It was this period that although there was not any group to advocate the social welfare, but the working class started to be formed along with Korean economy's growth. Second period was the 'Main Group Forming Period' for social welfare, ranging from after June Struggle in 1987 to 1997 Civilian Government. Since the June Struggle in 1987, it was the period that Korean politics system changed from the authoritarianism system to the democracy system, and in 1995, the Korean Confederation of Trade Union, a nationwide solidarity organization, was organized, and this labor representative organization started take the role as a main group for social welfare. Third period was the 'Development Period of Main Group Formation' for social welfare, ranging from since the Foreign Exchange Crisis to Lee Myung-Bak's Government in 2012. In this period, Korean society set the basic framework for a welfare nation through the solidarity between labor force and political parties, and as the political parties' welfare politics became vitalized along with the progressive political parties' appearance, the generation of welfare discourse was brought to Korean society. By looking around the development process of Korean social welfare policies from the perspective of main groups' formation, it was identified that the main groups for social welfare's formation and their roles brought rapid advancement in Korean social welfare policies. Additionally, the appearance of political parties as main groups for advancement of social welfare policies formed the foundation for Korean society to go toward a universal welfare nation. That is, Korean major political parties insist on expanding welfare policies, and especially, such policies are collected toward the direction expanding the universalism Implications in Korean social welfare policies' development process are that main groups' formation and their roles are the driving force of Korean social welfare's rapid advancement, and the appearance of political parties as main groups for social welfare has accelerated the speed of Korean society's welfare nation construction, and its direction goes toward a universal welfare nation. In other words, it can' not help emphasizing the main groups' roles pursuing for the universal welfare in order to construct Korean society as a universal welfare nation, and especially, the solidarity between laborer force and political parties will be a crucial factor in constructing a universal welfare nation.
