A meaning of power quality has changed, which affects on an environmental change of existing electricity supply markets. Today, it should take both consumers and suppliers into consideration to develop information and communication technology and to increase the use of power and electronic equipments. As a result, it is necessary to develop a system to monitor power quality and to display data. In this paper, a system, as a power quality monitoring equipment, which can use protective replays with progress of microprocessor technology and provide information in the intranet/internet circumstances using web-based architecture is described.

Transmission pricing is one of important issues related to competitive electricity markets since rational pricing scheme ensures a fair competition between the market participants. Any application of marginal pricing method to transmission pricing may accompany revenue reconciliation to recover Transco's revenue requirements. This paper presents an alternative methodology on revenue reconciliation with customer benefit function and power flow.

HTS (High Temperature Superconducting) Power devices has the several useful characteristics from the technical and economical viewpoint. Possible application to the utility industry have been widely discussed in various research projects. For the successful introduction of HTS power devices into power system, establishing a proper R&D and marketing strategies through estimating the future market size are necessary. However, quantitative estimates of how well HTS power devices will serve their markets have been lacking. In this paper, we propose a estimation methodology of future market size for HTS power divices such as cable, transformer, generator, and motor, and also evaluate the future international and domestic market size by using proposed methodology.

The deregulation and structural reform of power markets have started from the early 90s, which has brought about new studies on the new environment. Regardless the market structure, however, power systems need to be operated and planned in a stable and reliable manner. Therefore, decisions on proper amount of operating reserves and their reliable operations are very important. Up to now, the decision processes of operating reserves depend mainly on experiences of operators in Korea. When Korean power market comes under private management, operating reserves would influence power rate as well as power Quality, Therefore, it is time to prepare reasonable operating reserve standards in a systematic way for the new environment. This study suggests the proper operating reserve standards considering rules of the power market in Korea. To verify the adequacy of the proposed standards, stability and frequency characteristics of the Korean power system are analyzed as well.

Energy markets of the Northeast Asia countries and in particular South Korea are perspective enough from the standpoint of export of energy resources from Russia. South Korea Power System has been rapidly growing. However, recently it has been confronted with difficulties in regard to constructing new Power Stations and especially Hydro Power Plants. Therefore it is mutually beneficial to build electric tie to South Korea in order to use highly effective Power of Northeast Asia. In this paper, we describe the maximum available transmission power through interconnected line without loss of stability in power system. For this simulation, the AC transmission system is assumed appropriate for this preliminary study. The transmission system will pass through territory of North Korea and connect to 765 kV Network near Seoul with long distance.

The primary purpose of Renewable Portfolio Standard (RPS) is to facilitate investment in renewable energy technology. Since emission trading program has similar purpose, it is conceivable to attempt to link RPS and emission trading program through interlinked markets. RPS in Korea with single REC and emission allowance markets has particular advantages for constructing linkages between two markets. This paper provides a real option model to examine investment effects of linkage of RPS to the trading program. Emission permit price and REC price are assumed to follow stochastic processes and renewable investment is irreversible. The result shows that linked market provides further incentive for renewable investment by raising managerial flexibility for power companies.

Purpose: This study aims to identify factors influencing the health-related quality of life among women merchants at traditional markets. Methods: Participants in this cross-sectional descriptive study included 121 women merchants. Data were collected from May 01 to June 30, 2019 using the patient health questionnaire-9 (PHQ-9), psychosocial well-being index-short form (PWI-SF), subjective health status, and HRQoL. Selected data were analyzed using descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression by applying the SPSS/WIN program 22.0. Results: The HRQoL was significantly different by age (F=5.87, p=.001), education (F=2.98, p=.022), working period (F=4.70, p=.004), exercise (t=2.20, p=.030), chronic disease (t=-2.57, p=.011), BMI (F=5.04, p=.008), depression (F=4.70, p=.004), stress (F=7.82, p<.001), and subjective health status (F=7.91, p=.001). Factors influencing the HRQoL for women merchants included BMI (β=-.35, p<.001), subjective health status (β=.33, p<.001), and stress (β=-.18, p=.021). The explanation power of this regression model was 29.8% (F=5.51, p<.021). Conclusion: BMI, subjective health status, and stress affect the HRQoL of the subjects evaluated. Therefore, there is a need for health management programs that may decrease stress, control the BMI, and improve the subjective health status of women merchants at traditional markets.

This Article examines the regulation of outsider trading under the Financial Investment Services and Capital Markets Act (the "Capital Markets Act"). Outsider trading occurs when a market participant who is not a traditional corporate insider trades securities based on either "inside" or "outside" nonpublic information. Unlike "inside" information, "outside" information is referred to as information not derived directly or indirectly from the issuer. "Outside" information includes both "corporate" and "market" information. "Corporate information" is information about events or circumstances which affect the company's assets or earning power. "Outside corporate information" is information about the company's assets or earning power not derived directly or indirectly from the issuer. "Market information" is information about events or circumstances which affect the market for a company's securities but which do not affect the company's assets or earning power. The Capital Markets Act prohibits both "temporary insiders" from using "corporate" information in trading securities and "outsiders" from using "market" information, such as (i) information regarding the initiation or discontinuance of a tender offer; or (ii) information regarding acquisition or disposition of stocks in bulk. However, the Act does not encompass circumstances (i) where an outsider trades securities based on confidential corporate information obtained through certain types of wrongful conduct; (ii) where an outsider trades securities based on corporate information obtained through eavesdropping; and (iii) where an outsider trades securities based on either outside corporate information or market information created by the outsider himself. In order to plug a few of the gaps left open in the law of outsider trading under the Capital Markets Act, this Article suggests that regulators adopt a relatively broad reading of the scope of ${\S}$ 178(1) of the Act, which is similar to SEC Rule 10b-5, to include outsiders with no relationship to the corporation that had issued the securities. Since ${\S}$ 178(1) of the Act does not require "deception" for liability, it would seem to evade the limitations imposed by the U.S. misappropriation theory. Key Words : Outsider Trading, Insider Trading, Material Nonpublic Information, the Capital Markets Act, Misappropriation Theory, Fiduciary Theory.

The research paper examines the influence of elections on the stock market. The study analyses whether the market reaction would be the same when a party wins and comes to power for the second consecutive time. The study employs Market Model Event study methodology. The sample period taken for the study is 2014 to 2019. A sample of 31 companies listed in Bombay Stock Exchange is selected at random for the purpose of the study. For the elections held in 2014, an event window of 82 days was taken with 39 days prior to the event and 42 days post event. The event (t0) being the declaration of the election results. For the elections held in 2019 an event window of 83 days was taken with 41 days prior to the event and 41 days post event. The results indicate that the market reacts positively with significantly positive Average Abnormal Returns. The findings of the study reveal that the impact on the market is not the same between any two elections even when the same party comes to power for the second time. The semi-strong form of efficient market hypothesis holds true in the context of emerging markets like India.
