Past studies on economic control charts for controlling process means assumed that the measures of a quality characteristic do not have measurement error. In practice, however, this assumption is frequently violated. In this paper, the economic design models of three control charts(Xbar control chart, Xbar control chart with warning limits, and CUSUM control chart) for controlling process means are developed on the assumption that the measures can have measurement error. The effects of measurement error on the process control cost and design parameters of three economic control charts are examined. According to the experiments done in this study, when measurement error exists, the economic CUSUM control chart has lower process control cost in comparison with two other control charts. When measurement error becomes larger, both the sample size and the sampling interval increase while the control limits decrease.

본 연구는 북한 계획경제의 실패로 나타난 빈곤화가 시장화를 통하여 극복되는 과정을 분석하였다. 계획과 시장의 융합으로 나타난 경제정책을 제도로 인식하고 7.1경제관리조치와 6.28신경제관리조치를 중심으로 시장화를 자생적인 시장화(1990~2001년), 유통중심의 시장화(2002~2011년), 생산중심의 시장화(2012~2017년)로 시대구분을 하고 주요사건, 경제순환구조, 경제행태를 분석하였다. 분석결과 첫째, 시장화의 과정은 농민시장 확대, 유통 중심의 시장화, 생산 중심의 시장화 그리고 금융 중심의 시장화로 계속 시장화가 진화되면서 빈곤화가 어느 정도 극복되어 가고 있다. 둘째, 기업제도, 농업제도, 금융제도가 시장경제 방향으로 진전되어가고 있으며 소규모 사유화부터 시작하여 대규모 사유화가 진전되고 있다. 셋째, 완전한 빈곤화를 탈출하기 위해서는 외자유치를 통하여 공업화 산업화를 건설해야 하는 상황에 놓여있으며, 농업개혁, 기업개혁, 가격개혁, 재정개혁, 금융개혁, 무역 직접투자개혁, 유통개혁 등 거의 전 분야에 걸친 경제체제 개혁이 되어 글로벌 경제에 결합시키고 그 과정 속에서 고용확대, 외화획득, 기술획득을 실현해야 한다. 이러한 일련의 경제구조의 변화 방향들은 공적부문과 중앙집권화(Public sector & centralized)에서 사적부문과 분권화(Private sector & decentralized)로 바뀌고 있다.

보이스 피싱은 해독능력이 약한 노인과 약자를 대상으로 사회공학적인 방법을 이용하여 경제적 피해를 유발시킨다. 최근 인접국과 연계조직에 의한 보이스 피싱이 많은 국민에게 경제적 손실과 정신적 파탄을 야기하였고 대한민국 전체로 보더라도 보이스 피싱으로 인한 국가경제손실 및 정신적 피해는 매우 크다. 최근 정부와 관련기관들이 보이스 피싱을 막기위한 보안시스템과 금융보안장치를 강화하고 있으나 보안효과가 얼마나 큰가는 검증하기 쉽지 않다. 본 논문에서는 보이스 피싱으로 인한 대한민국의 경제적손실과 보안장치강화에 따른 보안효과의 경제성에 관하여 살펴본다. 우리나라의 보이스 피싱 피해의 직접 피해액은 1,100억 원으로 나타나고 있으며 철저한 보안에 따는 잠재적인 경제적 효과는 연간 3,500억 원 규모에 이른다고 볼 수 있다.

At the current stage of globalization and European integration of Ukraine, the aspects related to the effective fight against corruption in the system of economic security of our country are receiving more and more attention, as they become a prerequisite for continuing reforms based on international funding. In order to consider this issue and solve this problem, the necessary step is to develop and implement real mechanisms of the system for detecting and preventing corrupt behavior, which are based on international anti-corruption standards. The leading component of this system is the management of corruption risks in the system of economic security in order to identify them and implement measures to reduce them. This study analyzes the corruption perception index in Ukraine in recent years, which showed a positive, albeit somewhat slow dynamics of its growth, indicating a gradual increase in overcoming corruption through the introduction of a number of anti-corruption measures and changes. It is proved that the current stage of socio-economic development of the country contributes to strengthening the processes of combating corruption and preventing corruption risks, creating an effective and efficient anti-corruption system of the state. The concept of "corruption" was studied, it was found that in the field of public administration it is considered from different positions and is closely related to the concept of "corruption risks". The essence and features of corruption risks are studied, the preconditions of their occurrence are formulated, the relationship between the causes of corruption risks and economic security in the field of public authority has been established. The system of corruption risk management is considered and its components are characterized. It is proposed to increase the effectiveness of anticorruption policy through the implementation of measures aimed at investigating the causes of corruption risks, as well as developed effective and effective means of reducing corruption risks within the system of economic security

Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a Lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem or landscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

The government of Vladimir Putin, which has been ruling Russia for a long period since 2000, has recently strived for the balanced development of underdeveloped regions and sustainable economic growth. Therefore, along with energy development in the Far East and Siberian regions, the government is promoting development projects on logistics and distribution infrastructure. It is also expanding the construction of innovative districts to develop cutting-edge technologies in the outskirts of Moscow. Amid these moves, South Korea is pushing for the New Northern Policy aimed at widening economic cooperation with European and North Asian countries to expand the scope and influence of the country's trade market. The previous year of 2020, marked the 30th anniversary of establishment of diplomatic relations between South Korea and Russia. In this context, this study was initiated to propose various measures for promoting economic cooperation and expanding trade between South Korea and Russia. Therefore, this study examined Russia's political and economic environment and explored its major industrial environment with a focus on the energy industry, innovative districts and infra facility. The study also examined the progress of a FTA between the Eurasian Economic Union, in which Russia currently takes the lead, and South Korea and recommended several measures to upgrade and accelerate economic cooperation between the two countries through research on a range of topics.

When a manufacturing system is designed, various kinds of evaluation methods are used for selecting the best alternative. Net present value, inner rate of return and payback period are popular quantitative measures for the economic assessment, but other qualitative measures should be considered for evaluation. The analytic hierarchy process(AHP) has been used as the popular method for the multi criteria decision making problem that considers both quantitative and qualitative criteria. This paper explains the process of economic assessment, and how to use the AHP for evaluating the designs of the assembly lines for lens module installed in mobile phone.

This paper is a study on the model that measures economic values for the non-market properties of e-Business. For development of this model, first of all, we reviewed the properties of e-Business service, and looked around the relation between customer satisfaction and/or payment value and e-Business properties. In addition, we checked the method to measure economic values of these properties. This measurement method is the contingent valuation method which is a method of measuring the value of the environmental product. We modified it to adapt to the e-Business. Finally, in this paper, we proposed an economic value model which measures the value of willingness to pay(WTP) to our objectives. However, there could be some restrictions at the time when surveying empirically. Therefore, the succeeding study should be done in order to improve these restrictions some day.

This paper is aimed to analyze how to evaluate the choice of optimal management measures and level of control in fisheries management under the costly and imperfect management system by comparing with costless and perfect management system that is commonly assumed in the analysis of fisheries regulations. Fishermen would set the level of fishing efforts at the point where the marginal fishing profit for fishing effort is equal to the marginal level of fine under costly and imperfect management system. Therefore, under the case where the marginal fishing profit is higher than the marginal level of fine, the level of fishing efforts would be made at the point which is higher than the level of fishing efforts made under costless and perfect management system and is not a point where the economic profit is maximized in regulated fisheries. From this conclusion, the fishermens avoidance activities against regulations as well as the level of control in fisheries management substantially have an influence on the choice of fisheries management instruments. According to the analysis of optimal fisheries management policy, the economic profits in regulated fisheries are determined by the level of fisheries enforcement costs and total fishing profits, in which as enforcement costs increase the economic profits decrease. In addition, the economic profits vary in response to the level of control in avoidance activities. That is, as avoidance costs decrease, the economic profits increase. The determination of optimal level of control in fisheries management should be made at the point where the marginal regulation costs are equal to the marginal profits from regulated fisheries, in which marginal regulation costs are different according to the type of management measures. And the level of profits changes in response to different levels of avoidance activities. The management measure that can maximize the difference between the marginal regulation costs and marginal profits from regulated fisheries should be chosen as an optimal fisheries management instrument.
