Since the late 1980s, there have been radical changes in the managerial environment of Y University Medical Center(YUMC). Externally, the competition among hospitals has intensified due to the establishment of universal health insurance in 1939 and the entrance of large enterprises into the health care industry in the early 1990s. In addition, government regulation of medical institution is becoming stricter. Also, consumer groups have continued to demand the respect for patient rights and improvement of the quality of medical services. Internally, the financial condition of YUMC has worsened, not only because weak control and poor mediation in its large-scale structure have made its operation inefficient, but also because the rates of increase in the prices of goods and labor have grown faster than any increases in revenues. This study on materials management at YUMC presents a way for YUMC to reduce costs and increase its productivity, thereby overcoming its financial difficulties and dealing with external pressures. This study utilized the case studies of the materials purchasing and medical supply management in the United States and the comparative analysis of management to suggest short-term and long-term alternatives for innovation in YUMC. The goals of the short-term alternatives for innovation are to centralize the purchasing and supply departments and to simplify the decision-making processes. Through these attempts, it is estimated that YUMC's costs could be reduced by $600,000 per year. In the long-term, it is necessary to consider introducing a Supply Processing Distribution(SPD) system and setting up a centralized electronic system for supply and inventory management, although it is difficult to estimate the effect of cost-cutting because of the lack of analysis data. Thus, YUMC should thoroughly analyze initial investment costs and economical efficiency generated from long-term alternatives.

인터넷 뱅킹 서비스는 기존의 오프라인 서비스에 비해 편리성을 제공하지만, 해킹 등에 보안에 대한 많은 문제점을 가지고 있다. 이에 대해 금융기관은 보안을 강화하기 위해서 공인인증서, 보안토큰, 보안카드 OTP와 같은 인증 방법들을 제공하여 취약점을 보완토록 하였지만, 해킹 사건이 끊이지 않고 발생하고 있다. 특히 기존 인증방법들은 메모리해킹이나 중간자 공격과 같은 해킹에 대해서 취약점이 제기되고 있어, 새로운 인증방법이 필요하게 되었다. 본 논문에서는 인터넷 뱅킹에서 전자금융거래를 할 때 사용자의 PC와 Mobile 기기에서 이중으로 인증을 받는 Two Channel 인증 방식을 제안하고, 기존의 방식들과 비교분석을 통하여 안전성 및 신뢰성 측면이 강화되는 것은 확인할 수 있다.

This study develops principles for determining and managing costs applicable to grants and cooperative agreements for basic research. We investigated financial management policies of funding agencies and foundations in the United States, United Kingdom, Canada, Germany, Japan and Korea. Also we surveyed opinions of researchers and research fund administrators in Korean universities. Based on our review of funding agencies and our survey, the recommended management policies for grants and cooperative agreements are as follows: (1) Cost Structure. Cost of a sponsored agreement is comprised of the allowable direct costs and allocable portion of the allowable indirect costs. Direct costs can be further divided into salaries and wages, equipment, and other direct costs. (2) Salaries and Wages. Salaries and wages applied to a grant are paid for services rendered to the project during the period of performance of the particular agreement. In order to give researchers financial incentive, researcher allowance can be paid up to 30% of his/her regular salary. (3) Equipment. Any property purchased with grants which has an acquisition cost of 5,000,000 won or more per item and a normal life expectancy of two years or more is defined as equipment. Expenditures for special purpose equipment are allowable provided the acquisition of items is necessary for the research supported by the grant. (4) Other Direct Costs. Other direct costs are comprised of travel (both domestic and foreign), materials, other costs. Other costs may not exceed 30% of total other direct costs. (5) Indirect Costs. Since there is no clear consensus on indirect costs and additional budget is necessary to support actual indirect costs, the practical policy at the moment is to give a research support expense in lieu of indirect costs. In the future, however, some form of actual indirect costs should be supported. This study develops principles for determining and managing costs applicable to grants and cooperative agreements funded by the Ministry of Science and Technology. This research can be applied to other governmental agencies to give consistency and uniformity in administration of grants and cooperative agreements.

최근 금융권 해킹사례를 통해서 알 수 있듯이 공격자는 금융회사를 직접 해킹하기 보다는 보안관리가 허술한 수탁자를 대상으로 해킹공격을 시도하고 있다. 이로 인해 위탁자는 수탁자에 대한 보안점검 및 통제를 강화하고 있으나 영세 수탁자의 경우 전산설비 부족 및 보안장비 도입 시 과도한 비용 발생으로 인해 정보보호 투자에 미흡하다. 본 논문에서는 신용카드사들로부터 개인정보를 제공 받은 영세수탁업체의 보안강화를 위해 개인정보 라이프 사이클 기준으로 취약점에 대해 알아 보고자한다. 취약점 해결방안으로 클라우드 컴퓨팅 서비스에 소송관리시스템을 구축하여 사용하고 데이터 전송구간은 가상사설망을 설치하여 기밀성 및 무결성을 확보한다. 또한 사용자 보안강화를 위해 사용자PC에 PC방화벽, 출력물 보안등의 설치를 통한 개인신용정보 처리 보호방안을 제시하고자 한다.

Objectives: The purpose of this study was to interpret regional disparities in the number of teeth sealed with pit and fissure sealants, identify the factors that affect these disparities and find solutions for the same. Methods: Data were collected from the National Health Insurance Service and Korean statistical information service using metropolis-city-rural area dental health infrastructure variables, regional health behavior variables, and local finance-related variables. Results: In 2015, the number of teeth sealed with pit and fissure sealants per 100 people was higher in the metropolis or city than in the rural area. There was a positive correlation between the number of teeth sealed with pit and fissure sealants and the number of dentists, dental hygienists, dental institutions, standardization rate of subjective awareness of well-being, standardization rate of brushing after lunch, and the proportion of welfare budget in the general budget. There was a negative correlation with the annual standardization rate of health institution use, the standardization rate of unused medical services, and the local government's financial independence. According to the final model of the multiple regression analysis, while the impact of infrastructure on dentistry was not statistically significant, the statistical significance of standardization rate of brushing after lunch, the local government's financial independence, and the proportion of welfare budget in the general budget were maintained. Conclusions: To reduce regional disparities in the volume of use of pit and fissure sealants, it was concluded that it may be effective to select regions with a consideration of the level of regional economic power, implement separate and appropriate policies and projects, and improve the awareness in residents.

This study investigated the influence of the quality of a business management consulting service and the mediating effect of utilizing a business management consulting service. For this purpose, data was collected from 200 self-employed workers of the Moonchang market in Dasejun, the Yongdap market in Seoul and the Jatgeoeul market in Gapyeong. The result of the study are as follows. First, it was found that the quality of interaction, the quality of the result and the quality of the physical environment have significant influences over peoples' financial aptitude. Second, it was found that the quality of the interaction, the quality of the result and the quality of the physical environment have significant influences over peoples' non-financial aptitudes. Thirds, the evaluation of a mediating effect of utilization of a business management consulting service on the relationship between the quality of a business management consulting service and business performance showed that it has a significant influence in all ways and so this, proved its mediating effect. Therefor, as one of the means to activate traditional markets in Korea, it would be beneficial to actively introduce a business management consulting service and this would achieve a better performance through efforts to change the perception of employees and consultants about post-management of business management consulting services.
