Following the idea of "what you measure is what you get," this paper discusses the necessity to improve the plan and management of Application Service Provider (ASP) service based on performance evaluation. The Balanced Scorecard (BSC) has been used as a tool for suggesting the measures that can evaluate performance of a company by considering both financial and non-financial perspectives. The current BSC does not provide techniques to formally define, verify, implement and analyze the performance measures of ASP. Therefore, we developed a methodology for strategy development of ASP service by analyzing the BSC performance measures. This methodology provides a strategy for improving ASP service. The methodology proposed in this paper provide executives with core parts for achieving vision as well as the corresponding interpretation model for developing strategy. The methodology consists of the following two phases: BSC and Importance-Performance Analysis (IPA) phase. The methodology is illustrated through a case study in each phase. The case study shows practical deployment of our methodology.

The objective of a traffic management system is to promote safe driving, low pollution, short travel time, and optimized traffic flow by naturally distributing the flow of traffic through the use of suitable telecommunications media. Such traffic management systems will be improved by integrating dynamic traffic data and two-way communication media because cars can work as sensors. The purpose of this paper is to help organizations trying to select the correct telecommunications media for minimal-cost investment options without loss of functionality. The wireless communications for an intelligent transportation system (ITS) are introduced in this paper. We describe which kind of telecommunication media are suitable. FM broadcast type media or cellular phone can be recommended to provide real time traffic and roadway conditions in the first stage of ITS, because existing broadcast base station or cellular network facilities can be used. It is expected that cellular radio network or satellites are used for communication. Finally, the strategy and deployment plan of an ITS are described based on selections of telecommunication media in Korea.

Femtocell networks can be a potential method for increasing the capacity of LTE networks, especially in indoor areas. However, unplanned deployment of femtocells results in co-tier interference and cross-tier interference problems. The interference reduces the advantages of implementing femtocell networks to a certain extent. The notion of Fractional Frequency Reuse (FFR) is proposed in order to reduce the impact of interference on the system's performance. In this paper, a dynamic approach for efficiently partitioning the spectrum is suggested. The goal is to enhance the capacity of femtocells, which will improve the performance of the system. The suggested strategy allocates less resources to the macrocell portion of the network, which has a greater number of femtocells deployed to maximize the utilization of available resources for femtocell users. The spectrum division would be dynamic. The proposed strategy is evaluated through a simulation using MATLAB tool. In conclusion, the results showed that the proposed scheme has the potential to boost the system's capacity.

It is truism to say that today's customers demand high quality products and services; nevertheless, nowhere is this more prevalent than in the medical industry. Korea's globalization has increased it's citizen's awareness of greater life expectancies and medical improvements in other regions of the globe. Therefore, it is universally essential that in order to be successful in the medical industry, vendors must meet the ever increasing demands of better educated customers. The purpose of this study was twofold: 1) The first objective was discover what health care services are in demand and the quality factors related to these services. 2) The second objective was to determine a strategy for improving health care service through quality function deployment(QFD). One hundred and ninety-five respondents were randomly selected and asked to fill out a questionnaire after having undergone treatment at a medical clinic, located in Daejon, South Korea. The questionnaire was designed to obtain information about both he clients' satisfaction with, and their sense of the value of the medical treatment they received. Penalty-reward analysis and QFD were used to interpret the survey results and to deploy the collective voices of the customers. The results of the penalty-reward analysis illustrated that the 'communication' service quality factor was classified into an excitement factor that incurs no penalty if not achieved but adds value if the requirement is exceeded. As a result of the QFD analysis on the 'communication' service quality factor, eleven strategic alternatives were prioritized, and isolated a vital service quality characteristic. This characteristic can be implemented to bring value-added changes for the improvement of health care services.

본 논문은 북한 핵전략의 유형적 특징과 전망을 분석하기 위한 것이다. 이를 위해 핵전략의 개념과 유형, 북한의 핵능력과 선언적 핵전략, 북한 핵전략의 운용상의 특징과 전망을 살펴본 후 결론에서 우리의 대응을 도출해본 것이다. 최근 북한의 핵무기 배치와 핵능력 증강은 우리의 안보와 군사적 대비태세에 매우 심각한 문제를 제기하고 있다. 핵전략이란 핵무기의 구성 배치 운용을 둘러싼 군사전략을 의미한다. 북한의 핵전략에 대한 연구는 북한의 핵무장이 실체화되었다는 매우 현실적인 가정에서 출발한다. 우리 국방당국이 북핵에 대한 대응책으로 선제공격, 미사일방어, 대량응징보복 개념을 제시하고 그 도입과 전개를 서두르는 것은 북한의 핵무장을 전제로 한 조치이다. 표출된 북한의 선언적 핵전략은 (1)'핵보유국법'상의 핵억제 보복전략, (2)핵선제공격론, (3)제7차 당대회에 나타난 '핵선제 불사용원칙으로, 그리고 북한 핵전략의 저의 및 운용상의 특징은 (1)기존핵국가 관행모방을 통한 비난회피, (2)선언적 핵전략을 통한 자신의 핵전략의 호도, (3)핵전력과 핵태세간 격차로 인한 핵전략의 미정착 등으로 각각 요약해 볼 수 있다. 북한은 개정헌법(2012.7), '핵무력과 경제건설의 병진노선(2013.3),' 그리고 핵보유국법(2013.4) 등을 통해 스스로 핵보유국임을 규정 선언하고 있다. 하지만 '핵보유국(핵국가)' 지위는 오로지 NPT만 부여할 수 있는데, 이것은 이미 닫힌 시스템이다. 현실적으로 우리가 당면한 북핵위협을 억제 극복해 나가기 위해서는 튼튼한 한미동맹과 긴밀한 한미 공조하에 북한핵의 억제는 물론 비핵화 무력화를 위한 우리의 단 중 장기적인 정치 군사적 대응책의 수립 이행노력이 긴요하다.

TDOA (time difference of arrival)와 FDOA (frequency difference of arrival) 정보를 동시에 이용하는 신호원 위치추정 기법은 단일 정보를 이용하는 경우에 비해 높은 정확도를 가지는 장점을 가지고 있다. 이러한 위치추정 기법의 추정성능은 수신단 쌍의 조합, 수신단의 기하학적 배치 특성 및 속도 등의 다양한 운용변수에 따라 크게 달라진다. 그러므로 전자전 시스템의 효율적인 운용을 위해서는 다양한 운용 조건에 따른 사전 성능 분석이 요구된다. 하지만 기존의 비 반복적인 위치추정 방법은 기준 수신단의 설정 및 수신단 배치 형태에 제약을 가진다. 따라서 본 논문에서는 임의의 다양한 수신단 조합과 배치 형태에서 적용이 가능한 Gauss-Newton 기법을 유도하고 이를 통해 위치추정을 수행한다. 또한 모의실험을 통해 TDOA/FDOA 융합 기반 위치추정 방법과 단일 TDOA 또는 FDOA를 독립적으로 사용했을 때의 성능을 비교 분석하고 CEP (circular error probability) 평면을 이용하여 융합 기반 위치추정 방법이 독립적 방법에 비해 상대적으로 높은 추정 성능을 가짐을 보인다.
