This research investigates economic characteristics of 2 of 2 runs rules under the Shewhart $\bar{X}$ control chart scheme. A Markov chain approach is employed in order to calculate the in-control average run length (ARL) and the average length of analysis cycle. States of the process are defined according to the process conditions at sampling time and transition probabilities are derived from the state definitions. A steady state cost function is constructed based on the Lorezen and Vance(1986) model. Numerical examples show that 2 of 2 runs rules are economically superior to the Shewhart $\bar{X}$ chart in many cases.

New technologies and techniques to extract natural gas and gas liquids, as well as petroleum, from shale rock have greatly altered expectations for North America's capacity to produce energy products. As a result of innovations such as hydraulic fracturing, some government, industry, and academic observers have predicted that the United States will soon become energy self-sufficient and possibly become a net exporter of natural gas and petroleum. This paper will cover literature review and measure the potential impacts on economic growth and development. Fracking, renewable energy are just a few of the things that have reshaped the energy picture over the past 20 years, how much it will change in the next 20 years and the impacts on the economy will be discussed.

The United Kingdom and the United States are designating and implementing enterprise zones for the purpose of promoting the revitalization of the local economy. However, there are still mixed views on the effectiveness of the Enterprise Zone's policies. At this point, the purpose of this study is to look at policies in the form of enterprise zones in the country and see how these policies affect the revitalization of the local economy. As a result of the analysis, the areas designated as enterprise zones were becoming more economically vitalize than those that were not. In addition, it was analyzed that redundant designation of enterprise zones has a greater effect on regional economic revitalization than single designation.

Since 2006, the number of completed high-rise buildings over 200 meters have increased rapidly. Although there were some short-term cyclical troughs, the overall trend has still been growing. No longer constrained by technological limits, the development of high-rise buildings now depends on cooperation and compromise between social, economic, and political factors. This article extracts statistical data from the Council on Tall Buildings and Urban Habitat (CTBUH) to focus on the completion of high-rise buildings of 200 meters and above over the past 20 years from 2000 to 2019. Similarities and differences in the number, distribution, and function of high-rise buildings are analyzed, The paper also compares the impact of different political and economic environments on the development trends of high-rise buildings in China, the United States and the UAE.

This paper examines how APEC has transformed itself into an international forum for the vision of regional integration. It aims to quantify the documentation produced by the international organization and provide quantifiable evidence that aligns with prior knowledge rather than relying solely on intuition. For this purpose, I use various text mining techniques to extract multi-dimensional features from the text of APEC Leaders' Declarations from 1993 to 2023. In terms of interest and expectations for APEC as a forum, it is found that members have experienced two major peaks and troughs over the last three decades. It is found that the change point coincides with the Asian financial crisis of 1997 and the tensions between the United States and China since 2017. To explore more various aspects of economic integration in the Asia-Pacific region, this study also considers how consistently APEC has been an international forum for addressing issues, which members are active, and how members have clustered based on their views of APEC.

본 연구는 최근 세계 주요국(미국, 중국, 독일, 일본, 대만)의 산업혁신정책의 목표를 3대 분야 6개 세부목표로 분류하여 평가한다. 3대 분야의 첫째는 '기존산업과 미래성장'이라는 전통적 산업정책 목표인데 이는 다시 '기존산업 경쟁력 강화'와 '미래 성장산업의 육성'이라는 두 세부 목표로 나뉜다. 둘째는 '환경과 삶의 질' 분야인데 이는 '국민의 삶의 질 개선'과 '환경과 지속가능성'으로 구분된다. 셋째는 '공급망과 경제안보'인데, 이는 '공급망 안정성 확보'와 '경제안보'로 세분된다. 미국은 미·중 패권경쟁 상황 속에서 상대적으로 공급망과 경제안보를 중시하는 반면, 중국은 전통적 산업정책을 추구하여 왔으나 최근 공급망과 경제안보도 고려하기 시작했다. 독일과 일본은 전통적 산업정책과 함께 환경과 삶의 질뿐만 아니라 기술주권 및 공급망 안정도 중시함에 따라 산업정책의 3대 분야를 골고루 중시한다고 볼 수 있다. 대만도 비슷하다고 볼 수 있으나, 최근 중국의 위협에 따라 경제안보를 중시하기 시작했다. 한국의 경우, 경제패권국인 미·중과 달리 '경제안보'가 최우선 순위가 아닐 수 있다. 오히려 독일과 같이 국가 간 연대와 협력에 기반한 '공급망 안정성', '기술주권' 확보가 더 적절하여 보인다. 즉, 미국이나 독일 및 일본과의 기술격차를 줄이고 넘어서기 위한 '미래 성장산업과 기술의 육성'이 여전히 중요하다. 결론적으로 한국은 3대 분야에 대해서 비슷한 수준으로 가중치를 두어 기존산업과 미래산업을 중시하는 '전통적 산업정책'을 지속하면서, 일단 리스크 관리 차원에서 '공급망 안정성 확보'에 단기적으로 가중치를 둘 필요가 있다. 한국적 상황에서 안보란 방위산업 육성이나 식량안보가 더 적절하다.

The subject of this study is a cohort of elderly women who are older than 60 years of age and reside S city in and Jeonnam. The sample size of this study is 386. The statistics used for data analysis were frequency, percentage, mean, standard deviation, reliability, ANOVA, correlation, and multiple regression analysis through the SAS package program. The major study result were as follows. First, the physical satisfaction of elderly women is low, and the life satisfaction of the married group is higher than for the widowed group. Second, according to the results. For the women from the married group, the effect were from economic state, age, and physical satisfaction. There were also significant interaction effects according to economic state$\times$physical satisfaction, age$\times$economic state$\times$physical satisfaction, and age$\times$physical satisfaction. As for women from the widowed group, the effect were from physical satisfaction, economic state, and age. There were also significant interaction effects according to economic state$\times$physical satisfaction, age$\times$physical satisfaction, age$\times$economic state$\times$physical satisfaction, and age$\times$economic state. Fourth, the married group gave significance to life satisfaction, economic state, physical satisfaction, and age. The group of widows gave significance to life satisfaction, physical satisfaction, economic state, and age. The results of this study suggest that we should be concerned about the physical satisfaction of older women and should foster a social atmosphere to establish a positive image of elderly women.

Sanctions by the international community can increase their effectiveness with the participation of major countries with global economic influence, and can lead to efficient sanctions against the target countries when different sanctions procedures and methods can be operated in an integrated manner. To this end, it is being carried out with the aim of maximizing the performance of sanctions through collective economic solidarity by inducing international participation centered on the joint agenda, such as drawing up a resolution for sanctions. In this study, the definition and purpose of sanctions imposed by the international community and by major specific countries were explained and an empirical analysis was conducted on the economic impact of each sanctions, focusing on the United Nations Security Council and the United States, which directly implement them. Based on the selected research model, the effects of economic sanctions on the international community and countries subject to sanctions by certain countries were mutually compared and analyzed in the data. Finally, the conclusion obtained from this study was stated and the implications were derived and the possibility of further research expansion was described.

생산함수이론을 이용하는 대부분의 연구는 IT활용의 결과로 경제 성장을 보고 있다. 그러나 몇몇 연구들은 경제 성장을 IT 투자의 결정요인으로 보고 있다. 이러한 결과가 산업 수준에서도 유효한지를 조사하기 위하여, 이 연구는 미국의 1997년부터 2007년까지의 산업 자료를 이용하여 양방향 인과성 분석이 가능한 그레인저 인과성 분석을 수행하였다. 많은 산업에서 IT 투자는 경제 성장에 영향을 주었으며, 몇몇 산업에서 경제 성장이 IT 투자에 영향을 주었으며, 몇몇 산업에서는 IT 투자와 경제 성장은 아무런 영향 관계가 없었다. 산업 수준의 IT자본과 산업총생산을 국가 수준으로 합산한 시계열 자료를 이용한 분석에서는 IT 투자와 경제 성장은 어떠한 영향 관계가 없었으나, 산업 특성과 시간 특성을 고려하는 산업 수준의 패널 자료를 이용한 분석에서는 양방향 인과 관계가 발견되었다. 이러한 결과는 IT 생산성 역설의 이유였을 수도 있다.

This paper examines issues concerning conflicts between arbitral awards and public interests, particularly with respect to economic sanctions. Sanctions have been widely used by political entities, such as States and organizations, as means to promote public interests and to resolve cross-border disputes. In particular, economic sanctions have been increasingly more visible in recent years due to the accelerating fragmentation of the international communities, and their magnitude and range of the impacts have grown accordingly. For example, the U.S. and the EU have imposed economic sanctions on Russia and related persons in response to Russia's invasion of Ukraine. The U.S. recently re-introduced a comprehensive economic sanction on Iran. One of the notable impacts of the sanctions, particularly economic sanctions, is that on international arbitration. Sanctions are essentially built on the notion of the protection of public interests, and public interests are some of the few grounds upon which recognition and enforceability or arbitral awards may be rejected. However, jurisprudence on such conflict between sanctions and arbitral awards have not been sufficiently addressed in Korea because court case and administrative decision records on this conflict have not been sufficiently accumulated. In this regard, this paper begins with offering a survey of the concept of public interests, economic and trade sanctions, arbitral awards and their enforceability, and the relationships between them. It then examines the mechanism upon which public interests, trade and economic sanctions may lead certain arbitral awards unenforceable. Next, the paper suggests judiciaries' balanced approach toward the public interests protected by trade and economic sanctions and the predictability and fairness in the enforcement of arbitral awards. Finally, this paper concludes with the methods of the implementation of such balanced approach.
