도심지의 확장은 도시주변의 가공 송전선로 일부분을 지중화하게 만들어 가공과 지중 혼합선로가 증가하게 되었으며, 혼합선로 자동재폐로 미시행은 전력계통의 안정도를 약화시키는 결과를 초래하였다. 혼합선로는 그 구성 형태에 따라 편단지중, 양단지중 및 중앙지중 혼합선로로 구분할 수 있으며, 그 형태별로 기설 디지털 거리계전기를 적용하여 자동 재폐로 하는 방식과 별도의 지중구간 고장검출장치를 설치하는 방식을 적용할 수 있다. 기설 디지털 거리계전기를 적용하는 방식은 별도의 비용 없이 기술적인 엔지니어링과 회로개선을 통하여 적용할 수 있으나, 설치되어 있는 계전기의 Type 별로 제약이 따르며, 지중구간고장검출장치는 기술적인 제약 없이 적용이 가능하나 설치비용과 설치장소가 필요한 단점이 있어, 대상선로의 중요성에 따라 구분하여 설치하는 유연성이 필요할 것으로 판단된다. 지중구간고장검출방식을 이용하여 혼합선로에 자동재 폐로를 적용하면, 일부분 지중화에 따른 전력계통 안정도의 저하를 막을 수 있다. 최근 급속하게 발달하고 있는 디지털 보호계전 기술과 광통신ㆍ네트웍 기술을 접목하면 지금보다 새로운 시스템의 개발이 가능할 것으로 판단된다.

The purpose of this study is to investigate how the perception of organizational fairness among travel agency employees affects organizational trust and organizational effectiveness. For samples, 231 valid samples were taken from September 1, 2020 to September 30, 2020. The analysis results of this study were analyzed using the statistical package of SPSS for Window version 22.0. Multiple regression analyses were performed for hypothesis testing, and the results of this study were as follows: First, the distribution fairness, procedural fairness and interaction fairness of organizational fairness have been shown to affect organizational trust. Second, organizational trust has been shown to affect organizational immersion, job satisfaction and turnover intention of organizational effectiveness. Third, it was analyzed that organizational fairness affects organizational effectiveness. Finally, organizational trust was confirmed to have a mediating effect in the relationship between organizational fairness and organizational effectiveness. It is important to gain the trust of employees based on the hypothesis test results and to ensure fairness is recognized for positive effects.

The purpose of this work was to present a model of how aerial self-service characteristics affect user behavior and to clarify the relationship between these factors. The time range of the study was set for the base year in 2021. The target range was ordinary adults aged 20 or older who had experience using self-service devices while touring abroad within the past three years. The survey method was conducted using a mobile, self-inputting questionnaire method through a survey company. A total of 214 copies were distributed and recovered, and a total of 189 copies were used for empirical analysis, except for 25 questionnaires with low response rates or biased responses. Empirical analysis was analyzed using the SPSSWIN Ver 22.0 statistical package program after questioners were collected. A total of six hypotheses have been established to achieve the objective of this study. The hypothesis test confirmed that six out of six hypotheses were adopted or partially adopted, and the relevance of aviation self-service characteristics to the effect on users' behavioral intentions was verified. In this study, the time range was set to three years in consideration of Covid-19, but there may be time gaps that can cause distortion of memory, so future studies need to re-scope the time range to derive the results.

This study examines how the service environment of specialized rural tourism villages influences on service value and tourist's revisit intention, and also investigates the influences and correlations of each factor with considering tourists' behaviors and other previous similar studies. The aim of this study is to help central and local governments to establish effective tourism policies in the future. For the empirical analysis, after conducting a questionnaire designed with self-filling within type in 2 specialized rural tourism villages near the metropolitan area, 204 effective questionnaires were used as an analytical data. With considering the correlations between the service environment of tourism destination and the variables of service value, we can state that the factors of physical service environment such as accessibility, cleanliness, attractiveness and convenience have notable positive(+) correlation with the service value functional value and emotional value as examples. With considering the correlations between service value and the variables of revisit intention, we can possibly maintain both perceptive value and emotional value have notable positive(+) correlation with revisit intention. Therefore, the study revealed there is notable positive(+) correlation among all the study variables, showing consistent direction with the study hypothesis. Physical service environments have an effect on service value, especially since the attractiveness factor has the biggest effect on the service value and revisit intention, with improving physical service environment and external image of service workers and strengthening the service education.
