This paper evaluates the efficiency of mobile content firms through a hybrid approach combining data envelopment analysis (DEA) to analyze the relative efficiency and performance of firms and principal component analysis (PCA) to analyze data structures. We performed a DEA using the total amount of assets, operating costs, employees, and years in business as inputs, and revenue as output. We calculated fifteen combinations of DEA efficiency in the mobile content firms. We performed a PCA on the results of the fifteen DEA models, dividing the mobile content firms into those having either 'asset-oriented' or 'manpower and experience-oriented' efficiency. Discriminant analysis was used to validate the relationship between the efficiency models and mobile content types. This paper contributes toward the construction of a framework that combines the DEA and PCA approaches in mobile content firms for use in comprehensive measurements. Such a framework has the potential to present major factors of efficiency for sustainable management in mobile content firms and to aid in planning mobile content industry policies.

For a commercial building, property managers play an important role in maximizing the benefit by reducing cost and increasing revenue in the operation and maintenance phase of the building. However, most of property managers are spending their time in monitoring facility managers who have little impact on cost reduction and maximization of operating profit. The industry practitioners have difficutlty in increasing the efficiency of thier work due to this work environment. In addition, both property managers(PMr) and facility managers(FMr) are dependent on the paper drawings and manuals, which can worsen the inefficiency and human errors are inevitable. This study aims to contribute to improvement of the current practice by developing a novel algorithm that autmatically links the facility information with 3D model, which can provide an efficient property management for commercial buildings.

This study is conducted to estimate economic ripple effects of subsidiary services of hospitals. Using the Input/Output Analysis, this study analyzes production inducement effect, added value inducement effect, and labor inducement effect. Also, it assesses potential economic effects of the subsidiary services of which the scope is expanded as the government's proposed in 2014. Data regarding hospital subsidiary services and economic effects are obtained from the hospitals' financial statements on the National Tax Services and the Bank of Korea. The major results of this study are summarized as follows; subsidiary service profits of hospitals are 466 billion won and rent profits of hospitals are 152 billion won. Of these, the rate of subsidiary service profits in tertiary hospitals is about 66% of total subsidiary service profits. Producement inducement effect of subsidiary services of hospitals is higher than that of total industry, service industry and medical service industry. Added value inducement effect of subsidiary services of hospitals is higher than that of total industry, manufacturing industry, service industry and medical service industry. Job position inducement effect of subsidiary service in hospitals is higher than that of total industry, service industry and medical service industry. Also, employment inducement effect of subsidiary service in hospitals is higher than that of total industry and medical service industry. The results may suggest that subsidiary services revenue in medical institutions contribute to improving operating profits. Facing with intense market competition and pressures to control health care costs, hospitals may need to determine whether subsidiary services help boost their profitability and improve customer satisfaction.

민자도로의 차량 통행료 할인은 비일몰형(경차 등)과 일몰형 2가지로 구분된다. 일몰형이란 입법자가 정한 특정기한이 도래하면 법령의 전부나 일부의 효력이 상실되도록 규정하는 조항을 말한다. '일몰' 대상 할인차량의 종류는 심야시간대 운행되는 화물차량, 비상제동장치를 부착 버스, 전기 및 수소를 사용하는 친환경차가 있다. 민자도로에서 비일몰형으로 규정된 할인차량의 감면된 통행료는 지금까지 정부가 모두 운영사에게 보조금으 로 지급하였지만, 이들 일몰 차량들에 대한 통행료 감면에 따른 비용은 민자도로 운영자에게 전혀 지원되지 않았다. 최근 전기수소차는 2016년 1.1만대에서 2022년 41.9만대로 매년 150 % 이상씩 빠르게 증가하였다. 비록 이들에 대한 통행료 50 % 감면혜택이 2024년까지 한시적으로 적용되더라도 이러한 전기수소차의 빠른 증가는 민자도로 운영기관에게는 통행료 수입 감소 부담을 더 높이게 된다. 본 연구는 일몰형 통행료의 감면 보조금 지원 필요성과 방법을 제시하기 위하여, 2023년 말 기준 전국 22개의 민자도로 운영사 중 8곳의 통행량과 통행료 감면금액 자료를 분석하였다. 우선, 비일몰형에 대해 지급된 보조금은 2022년 875억원으로 총 통행수입 대비 18.6 %이었다. 그러나 일몰형은 보조금 지급 사례가 아직까지 없었다. 실시협약 상 통행료 면제 및 감면 비율은 운영사별로 전체 통행량의 4.0~5.65 %로 설정됐다. 일몰 대상에 대한 감면 통행차량의 비율은 2017년 0.85 %에서 2022년 2.79 %로 크게 늘어났다. 여전히 실시협약에서 정한 통행량 감면 비율 이내에 있지만 감면금액 비율로 보면 2022년 총 통행수입 대비 4.2 %(255억원)로 높아진다. 전기수소차 등록대수가 빠르게 증가되는 상황에서 민간도로의 영업이익 손실도 점진적으로 증가되고 있다. 정부의 친환경차량 등록 확대정책에 맞춰, 이제는 일몰 대상에 포함된 통행료 감면 대상차량도 보조금 지급대상의 범위로 포함시키는 방안을 적극 검토할 때가 되었다. 본 연구는 통행료 감면보조를 위한 최소 비율로 도로 관리관청과 민자운영사간 맺은 4.0 %를 최소 기준으로 정하였다. 이를 초과한 금액에 대해서는 전액 보존되도록 하는 3가지 정책 대안을 제시하였다. 각 대안은 친환경차에 대한 정부의 확대 정책을 손상시키지 않으면서 기존 내연기관차를 대체할 수 있는 혜택 유지와 민자 도로 운영기관의 적정한 통행료 수입 유지라는 두 가지 조건을 모두 충족할 것으로 예상된다.

With large corporations entering into the foodservice market, competitions among those foodservice providers became intense, leading to differentiated quality services in terms of portioning out the meal, its portion and waiting time, not to mention food quality. The purpose of providing foodservice is to satisfy its customers, to secure optimum level of profits, and attain continuous quality improvement. To have such purpose attained, all other factors affecting the foodservice should be allowed to play a role. The intensity of the work performed by the employees should be maintained at a steady level and systematically controlled. 'Service First’ principles upholding that customer satisfaction comes from good service should be applied at all times; customer satisfaction comes from the satisfaction of the employees. Customer satisfaction through good service will contribute to an increase in revenue which we get by subtracting operating expenses from the total sales, as it will lead to concluding a long-term supply contract or renewing the existing contract. To keep the operating expenses to the minimum level, it is important to effectively perform the cost control. Since personnel expenses occupy a large portion of the operating expenses, it is imperative to effectively control the labor costs. For this reason, this study will present an effective program for disposition of men with a large organization being centered around, where the number of people served at the mess hall varies greatly depending on a day of the week and a mealtime of the day.
