현재 금융거래 서비스에서 보편적으로 사용하는 RSA와 ECC 같은 공개키 암호 알고리즘은 양자 컴퓨터가 실현되면 더 이상 안전성을 보장할 수 없으므로 기존 레거시 알고리즘을 양자내성암호로 전환해야 한다. 하지만 다양한 서비스에 사용 중인 알고리즘을 교체하는 데에는 상당한 시간이 소요될 것으로 예상된다. 다가올 전환기를 대비하기 위하여 두 알고리즘을 결합하는 하이브리드 방식에 관한 연구가 필요하다. 본 논문에서는 레거시 알고리즘인 ECDH 알고리즘과 양자내성암호 알고리즘인 NTRU 알고리즘을 결합하여 세션키를 생성하는 하이브리드 세션키교환 프로토콜을 제안한다. TLS 1.3 기반 하이브리드 키 교환을 위해 IETF에서 제안한 방식들을 적용해본 결과 기존 금융거래 세션 보호 솔루션에 우리가 제안한 프로토콜을 사용하면 안전성을 강화할 수 있을 것으로 기대된다.

Recently, Certificate has been loosed 100 times in a four years as Phising or hacking. The service that use certificate in financial services occurs practical and secure issues. Therefore, the Korea government abolished the mandatory system used in the certificate service. However, they did not provide a replacing method for a certificate. And is not to fill the gaps of the certificate with one time password or secure card. Therefore this paper is propose the alternative method with total authentication service, that is lead the more secure electronic commercial.

1997년의 외환위기를 계기로 국내 금융산업에 본격 적용된 구조조정은 자산부채인수 (P&A, Purchase & Assum ptions), 합병인수 (M&A， Merger & Acquisition), 금융지주회사라는 방법을 통하여 시행되었다. 자산부채인수방식은 구조조정 초기 5개은행, 금융지주회사 방식은 정부주도하의 우리금융지주회사와 순수민간에 의한 신한금융지주회사, 합병인수방식은 최근의 우량은행간 합병으로 대형화 및 겸업화를 도모한 국민 ${\cdot}$ 주택은행이 있다. 이러한 과정에 필수적으로 수반되는 가치평가의 항목에 대하여 살펴보고자 한다.

Railway stations consist of site, structure, skin, services, space and stuff. The depth of modernization will depend on which of these layers is defective, and on the degree to which the layers are embedded. Stations function as circulation spaces, operational premises, commercial premises and beacons. The type of modernization will depend both on the functions, and on the social (and financial) benefits to be gained by improving the performance of each function. Modernization will bring stations up-to-date, and enabling them to deliver optimal performance.

As we enter the technology and knowledge-intensive era, standardization has become a key element to increase the sustainability of companies. However, standardization activities have not been proceeded well due to lack of relevant information, financial and human resources and complexity of the authentication process. Thus, in this paper, we analyze the effect of understanding the internal and external standard trends surrounding companies and recognizing the difficulties of standardization process on the needs of standard/standardization education. We suggest an experiment model and associated variables for analysis based on the previous studies. The analysis results from 1,000 companies that belong to telecommunication industry and electrical and electronics industry showed positive relationships among these three variables. Furthermore, we propose major policy directions for increasing standardization effect.

In this study, we empirically examine cross-sectional determinants of IT personnel size of Korean listed companies from year 2004 to year 2009. Also, cross-sectional determinants of IT personnel size involved in managing internal control over financial reporting (hereafter, "ICFR") were examined. IT personnel or IT workers are recognized as critical intangible resources comprising firm's IT capability. Although IT personnel are regarded as important resources, there are not much information about factors explaining the size of firms' IT personnel. Fortunately, the Korean governmant regulates that every listed companies should dislclose the number of IT workers and ICFR-related IT personnel in their annual reports. This study utilizes the mandatorily disclosed IT personnel data to analyze cross-sectional determinants of korean listed companies' IT personnel size. Empirical results show that profitability, uncertainty, leverage, industry types are statistically significant factors associated with the size of IT personnel.

As many organizations have adopted and implemented ERP systems, concerns about ERP performance also have increased. Former researches studied the ERP implementation of general large or medium size enterprises but there are not enough studies on ERP systems of a specific industry domain. In this paper, we introduce a case study on ERP adoption methodology of global leading company 'D' in shipbuilding and marine engineering industry. We examined ERP implementation background, method and scope and evaluated ERP performance in perspective of both quantitative and qualitative approaches. Quantitative research usually examines ERP performance based on financial statements and qualitative study typically examines organization change or improvement. As a result, ERP implementation in shipbuilding and marine industry can improve quantitative aspects such as cost, human resource and organization performance. As qualitative analysis, business process and tools can be unified and management transparency can be improved by ERP implementation. The result of this paper will be useful guideline for organizations which are considering ERP systems.

Health sub-centers, which have been established at myon areas by government policy, have provided a basic health care services for unfavorable rural conditions. Health sub-centers would be expected to serve for dweller's fundamental needs of primary health care services. But to accomplish it's function and role, the quality of physical facility should be enhanced as well as staff and financial resources. In this research, through the field survey of rural health sub-centers, the problems of facility planning and design were revealed. And then the basic data for architectural planning and design of health sub-centers were provided.

Climate change and energy security are major factors for future national energy policy. To resolve these issues, many countries are focusing on creating new growth industries and energy services such as smartgrid, renewable energy, microgrid, energy management system, and peer to peer energy trading. The financial and economic evaluation of new energy services basically requires energy savings estimation technologies. This paper presents the baseline load estimation method, which is used to calculate energy savings resulted from participating in the new energy program, using moving average model with heating degree days (HDD) and cooling degree days (CDD) adjustment. To demonstrate the improvement of baseline load estimation accuracy, the proposed method is tested. The results of case studies are presented to show the effectiveness of the proposed baseline load estimation method.

The rapid development of information technology has affected many industries, and made consumers receive new services that are completely different from those of the past. In the financial industry, various changes are taking place, such as providing the payment system which is easy to use and offering differentiated services. This study examined the factors affecting the intention to use mobile payment system. In particular, we considered both practical and emotional factors that affect the intentions. The mobile payment system, which is a new form of payment, is rapidly developing in China. In Korea, it is still in the beginning stage due to the legal regulations and the activation of alternative payment methods. This study, therefore, compared the differences in factors that affect the intention to use mobile payment system between Korea and China.
