This research suggests the estimation methodology of Logistics. This paper elucidates the main problems associated with estimation in the regression model. We review the methods for estimating the parameters in the model and introduce a modified procedure in which all models are fitted and combined to construct a combination of estimates. The resulting estimators are found to be as efficient as the maximum likelihood (ML) estimators in various cases. Our method requires more computations but has an advantage for large data sets. Also, it enables to detect particular features in the data structure. Examples of real data are used to illustrate the properties of the estimators. The backgrounds of estimation of logistic regression model is the increasing logistic environment importance today. In the first phase, we conduct an exploratory study to discuss 9 independent variables. In the second phase, we try to find the fittest logistic regression model. In the third phase, we calculate the logistic estimation using logistic regression model. The parameters of logistic regression model were estimated using ordinary least squares regression. The standard assumptions of OLS estimation were tested. The calculated value of the F-statistics for the logistic regression model is significant at the 5% level. The logistic regression model also explains a significant amount of variance in the dependent variable. The parameter estimates of the logistic regression model with t-statistics in parentheses are presented in Table. The object of this paper is to find the best logistic regression model to estimate the comparative accurate logistics.

플라톤의 비극적 영웅주의 비판

노경호(Roh, Kyung-Ho) 한국서양고전학회 2018 西洋古典學硏究 Vol.57 No.1

이 논문의 목적은 『국가』 2-3권과 10권에서 전개되는 플라톤의 시가비판을 『일리아스』에서 특히 잘 드러나는 비극적 영웅주의에 대한 비판으로 이해하려는 것이다. 시가 비판을 위해 먼저 플라톤은 3권과 10권에서 일관되게 시가의 모방을 ‘앎 없는 상태에서 보이는 대로의 재현’로 규정한다. 이런 모방의 의미에 따르면 시인의 모방은 세계와 신들, 인간의 운명을 그에 대한 앎 없이 그들에게 보이는 대로 그려내며 이야기를 만들어내는 활동이다. 모방의 산물인 이러한 시가는 비극적 영웅주의를 그 구체적인 내용으로 가지며, 이는 세계와 신들, 인간의 운명에 대한 비극적 인식과, 그 비극적 운명(죽음)을 극복하기 위해 명예와 명성을 좇는 영웅주의적 행동으로 이루어진다. 플라톤은 2-3권에서 신들과 인간의 운명 등에 대한 비극적 인식을 담은 구절들을 골라 비판하고 있는데, 이는 곧 정의로운 삶을 정당화하기 위해 플라톤이 극복하려 하는 ‘거짓된 판단’의 내용이기도 하다. 이는 곧 시인들이 만들어낸 세계에 대한 앎 없는 모방의 결과물이다. 10권에서 플라톤은 모방하는 시가가 전해주는 비극적 영웅주의를 ‘욕구의 지배’로 인해 생겨난 것으로 본다. ‘욕구의 지배’는 삶(즐거움)을 지속하고 죽음(고통)을 피하려는 본능에 따라 세계를 인지하고 그에 따라 행동하도록 이끈다. ‘욕구의 지배’에 의해 시인들과 그의 추종자들에게 세계는 비극적으로 보이며, 따라서 이성에 따르는 정의로운 삶 대신 영웅주의적 삶이 좋은 것으로 보인다. 하지만 비극적 인식은 모방의 산물에 불과하며, 영웅주의적 삶은 진정으로 고귀하고 훌륭한 삶이 아니라, 비극적 인식에 근거한 ‘탁월성의 영상’에 불과하다. The aim of this article is to interpret the critique of poetry in Plato’s Republic as that of tragic heroism, mainly contained in Homer’s Iliad. For Plato, the word ‘mimēsis’, the main concept on the critique of poetry, means the representation of “what the reality appears (= what appears to be the reality)” without the understanding of the reality. According to this meaning, poetic mimēsis is to make a story regarding gods, the world, and the fate of human beings through poet’s own words and actions without the understanding of them. The mimetic poetry contains as its content the lesson of tragic heroism, which consists of two aspects; one is the tragic view of gods, the world, and the fate of human beings, and the other heroic actions for overcoming of the fate, that is, of the death. In Books 2-3, Plato tries to expunge the lines related to the tragic view. The relation of this tragic view and heroic actions propelled by it in Iliad corresponds to that of ‘the false judgment (doxa)’ and ‘unjust action’ in the whole argument of Republic. In Book 10 Plato attributes tragic heroism, not simply mimēsis, to ‘the rule of appetite’, which means that a person sees his conditions and decides to act solely on instinct, pursuing life and avoiding death. As their instinct propels them, the poet and his followers view the world as tragic, and the heroic life as better than the just life. However, the tragic view is merely a result of mimēsis, and the heroic life is for Plato by no means noble or virtuous at all; it is only ‘the image of virtue’.

This study proposes the meaning and direction of product safety value management for product safety by examining the impact on product safety policies in terms of corporate social value amid the recent spread of responsible investment centered on ESG, and social value management. In this aspect, a product safety value management practice strategy was proposed to build a product safety society. The following are suggestions for product safety management in the era of the 4th industrial revolution. First, it is necessary to establish a systematic safety management network to prevent product damage and consumer damage from accidents and to prevent the spread in the changing product environment in the era of the 4th industrial revolution. Second, as complex and various smart products based on the Internet of Things are rapidly spreading, the need for safety management in new areas increases. Third, as the number of artificial intelligence products increases, the need for safety management in new areas such as software installed in products in addition to products increases. Fourth, in the era of the 4th industrial revolution, companies strengthen their safety responsibility for new convergence products, the government establishes policies for new convergence products and improves market monitoring functions, and consumers expand participation in safety management for new convergence products. , it is necessary to create a product safety ecosystem in which companies and the government participate. In consideration of such product safety management measures in the era of the 4th industrial revolution, product safety management promotion strategies are proposed as follows. First, a paradigm shift in product safety management is required. Second, consumer and corporate awareness of product safety should be raised. Third, product safety culture should be spread. Fourth, it is necessary to establish a product safety ecosystem in which consumers, companies, and the government all participate. Fifth, product safety and value management based on ESG management should be promoted in all economic entities of companies, the private sector, and the government. Based on the definition of product safety value management, the product safety value management practice strategy is as follows. First, product safety value management should be practiced with the objective of product safety value management as ‘creating economic value and social value through product safety value at the same time’. Second, in the process of product safety value management, the organizations strategy, governance, process and system should be established with the goal of product safety value management, and the organization should be operated on this basis. Third, it is necessary to accurately recognize that the subject of product safety value management is entrepreneurs, members, and stakeholders, and practice product safety value management.

According to the housing census of the National Statistics Portal, the number of vacant houses nationwide is 1,511,306 as of 2020, and the number of vacant houses has been increasing since 1960. The number of vacant houses across the country is expected to accelerate due to changes in socio-economic conditions such as population decline, aging, and deepening imbalance in regional growth. Vacant houses can adversely affect the security of the surrounding area and the residential environment, which may reduce the efficient use of housing and land. A vicious cycle may occur that progresses more rapidly. In this study, the vacant house management system, such as the main policies of vacant house management, the subject of vacant house management, management targets, and related institutional foundations, was investigated and analyzed to analyze the current status and problems, and based on the results, a vacant house innovation ecosystem model for Glocal Innovation was developed. was proposed as follows. First, it is desirable to set up the Ministry of Land, Infrastructure and Transport as a control tower to comprehensively manage the vacant house innovation management that is being carried out by various central governments and local governments such as cities, counties, and districts nationwide. Second, it is desirable to establish a vacant house innovation strategy. Third, it is desirable to establish a comprehensive management system for vacant house innovation. Fourth, it is desirable to strengthen the role and obligations of vacant house owners. Fourth, it is desirable to efforts are made to prevent blind spots in vacant housing innovation-based policies. Fifth, it is desirable to introduce vacant house innovation plans for each type of vacant house owner. Sixth, it is desirable to introduce vacant house innovation-based product safety value management. Product safety value management is “creating social value through economic value and product safety value through the utilization of business opportunities and resources based on organizational strategy, governance, process and system. It is a process of creation”. Seventh, it is desirable to actively introduce startup programs based on vacant house innovation.

글로벌 경제위기 상황에서 국가 경쟁력 강화를 위해서는 중소기업의 생산성 향상을 위한 전략적 방안 수립이 필요함. 세계 경제 패러다임의 급격한 변화와 미국과 유럽의 금융위기등으로 인한 글로벌 경기침체의 가속화로 중소기업을 포함한 우리나라 전체 기업의 경영환경이 악화되고 있음. 세계경제가 회복되지 않은 상황에서 대기업보다 더 어려운 성장 기반을 가지고 있는 중소기업의 생산성 향상을 통한 경쟁력 강화가 이루어지지 않으면 경제회복이나 고용창출은 기대하기 어려움. 기후변화 대응, 에너지 및 자원 가격 상승 등 글로벌 환경 변화에 따른 새로운 성장과 복지 모델이 필요하며 이에 맞는 중소기업의 역할 설정이 긴요함. 정부의 2013년 최우선 정책과제인 경제 민주화, 일자리 창출, 중산층 재건을 위해서 중소기업의 생산성 향상을 위한 전략적 방안 수립이 필수적임. 한국경제의 생산성 측면에 있어 양극화 되어 있는 대표적 부문 중의 하나가 대기업과 중소기업이라는 기업규모 간 생산성 격차임. 그동안 대기업과 중소기업의 생산성 측정을 위한 기초통계 부족으로 인해 이영역에 대한 연구가 충분히 이루어지지 못함. 기업체 및 사업체 수준의 기초통계가 지속적으로 보완된 관계로 이에 대한 생산성측정·분석 및 중소기업의 생산성향상 개선 방안을 모색할 필요성이 제기됨. 따라서 대기업과 중소기업 간의 생산성 비교분석 및 중소기업 측면의 생산성 현황과 문제점의 심충분석을 바탕으로 다양한 접근 하에서 중소기업 생산성 향상방향모색을 통하여 실천 가능한 정책중심의 중소기업 생산성향상 방안을 도출하는 것이 본연구의 목적임.

The Internet is flourishing and the World Wide Web is growing at an exponential rate. A fundamental concept of Intranet, the so-called second wave, was introduced only a few years ago. Intranets have been embraced by corporate users of information services and made substantial inroads in strategic vision documents and procurement practices. Business organizations have come to the conclusion that they require an extensive data repository in order to acquire a competitive advantage in a dynamically change market. This rich assortment of data must further be delivered and deliverable enterprise-wide in a secure and cost-efficient manner. Information technology(IT) has created the Intranet as a vitally important mechanism for the storage, dissemination, and even the analysis data. The present study is an attempt to develop a more through understanding of the potential and actual impact of the Intranet on organizational functions and activities. Expecially, it also consists of an effort to assess the impact of the Intranet on Profitability. The research also addresses the issue of how the Intranet affects Profitability and shapes or modifies business activities. The results of literature review and study revealed that middle managers believe that the extent of the Intranet use is significantly related to improvements in overall organizational functions and activities. While communication, decision-making, productivity, work collaboration, and business activities are all enhanced by Intranet use, Profitability appears to be most dramatically improved by Intranet use.
