Aviation/tourism industry has a unique characteristic of high inter-dependance between customer and service-provider. It is the mental condition of service-provider that could influence on the attitude of the service-provider. Thus, it is important to manage the mental condition of the service employees to enhance a company's financial performance. This paper tries to analyze the combined model of both policy acceptance and service profit chain(SPC) models. First, service policy acceptance model tells how the service policy acceptance, which consists of policy compliance, trust, participation and policy failure, would influence on SPC model. According to empirical research, it was found that both the employees' policy compliance and the policy trust have a positive significant impact on their participation on service policy. In the policy acceptance model, the employee's voluntary participation based on their trust and compliance of the policy was proven to have a positive effect on increasing job satisfaction and customer orientation. Regarding SPC model, their participation in the policy had the strongest impact among variables on customer orientation. Such results implies the employees' participation on the policy could become the starting point to enhance the customer value.

Uroflowmetry is a non-invasive clinical test useful for screening benign prostatic hyperplasia(BPH) common in the aged men. The current standard way to obtain the urinary flow rate is to continuously acquire the urine weight signal proportional to volume over time. The present study proposed an alternative technique measuring pressure to overcome noise problems present in the standard weight measuring technique. Experiments were performed to simultaneously acquire both weight and pressure changes during urination of 9 normal men. Noise components were separated from volume signals converted from both weight and pressure signals based on the polynomial signal model. Signal-to-noise ratio was defined as the ratio of the energies between signal and noise components of the measured volume changes, which was 8.5 times larger in the pressure measuring technique, implying that cleaner signal could be obtained, more immune to noisy environments. When four important diagnostic parameters were estimated, excellent correlation coefficients higher than 0.99 were resulted with mean relative errors less than 5%. Therefore, the present pressure measurement seemed valid as an alternative technique for uroflowmetry.

본 논문에서는 다중객체 인식 시스템과 같은 저용량 데이터전송의 저전력 무선센서네트워크 분야에 적용 가능한 새로운 펄스 방식의 저 속도 무선 비동기식 UWB(Wireless Asynchronous Ultra-Wide band) 시스템을 제안하고 이를 설계 및 구현한다. 특히, 펄스방식의 저전력 UWB시스템을 구현하기 위해서 전형적인 통신시스템의 수신기 구조인 RF단의 믹서, 상관기와 A/D 변환기를 없애고 최대한 단순화된 구조의 무선 비동기 방식의 UWB 송수신기를 설계하였다. 또한, 설계된 무선 비동기식 UWB 시스템의 테스트베드를 구현하였고, 구현된 무선 비동기식 UWB 시스템의 응용 시스템 예로 홈 내 또는 강의실과 같은 곳에서 하나의 송신 무선 비동기식 UWB 송신기 측에서 10 m 거리 범위 내에 있는 다수의 수신 무선 비동기식 UWB 측으로 동시에 그림이나 글을 전송할 수 있는 1:N HD(Half Duplex) 방식의 저전력 무선 캔버스(CANVAS) 시스템을 실제 구현하였다. 이를 통해, 제안된 무선 비동기식 UWB 시스템은 LOS(Line of Sight) 채널상태의 전송거리 10m에서 안정적으로 최대 115kbps 급의 전송속도가 지원 가능함을 확인하였다. In the parer, we design a non-coherent UWB system by adopting the architecture of a simplified asynchronous transmission and the edge-triggered pulse transmission, which makes e system performance independent of the share of the transmitted waveform, robust to multipath channels. The designed non-coherent UWB transceiver architecture has an advantage of the simple realization since any mixer, high-speed correlator, and high-sampling A/D converter are not necessary at the cost of performance degradation of about 3dB. Further, the designed non-coherent UWB transceiver is actually implemented with the wireless CANVAS prototype testbed in short range indoor application environments such as a lecture room. The implemented prototype testbed is proven to offer the data rate of 115kbps on the conditions of Peer-to-Peer(P-to-P) in the indoor channel within the range of about 10m.

War has been existing with human history. There seems to be two approaches of war study. One is to deter war among politicians, the other is to get victory in a war among soldiers. Many scholars and soldiers tried to find out the way of victory at war, that is, the major factors of victory at war. They found out some factors that dominate the victory of war through numerous experiences of war, and we call it 'principles of war'. The principles of war which we are using has been shaped during past three centuries. But, nowadays rapid change in the environment of war has brought the change of features of warfare and method of waging war. NCW may be the most typical example of new environment of war. The Iraque War may be the most recent modem war performed under the NCW environment. And the Iraque War brought up the need of new principles of war adaptable to the NCW environment. This article is focusing on new principles of war that comprehends future wars. I suggest that some principles of war which we are using should be supplemented to be understood its own conception, and new principles are needed such as principle of paralysis, principle of synchronization & Integration.

개방 스터브를 이용한 이중 모드 마이크로스트립 링 공진기의 소형화 및 대역 통과 필터 설계

최성수,박동철,Choi, Sung-Soo,Park, Dong-Chul 한국전자파학회 2007 한국전자파학회논문지 Vol.18 No.6

본 논문에서는 이중 모드 마이크로스트립 링 공진기의 크기를 줄이기 위해 4개의 개방 스터브를 삽입하였고, 이를 이용해 중심 주파수 2 GHz에서 100 MHz의 대역폭을 갖는 대역 통과 필터를 설계하였다. 삽입된 개방 스터브의 캐패시턴스 값에 따라 링 공진기의 크기를 조절할 수 있고, 스터브들의 두 가지 조합 형태 각각의 경우에 대역 통과 필터를 설계할 수 있음을 보였다. 제안된 구조를 2단 대역 통과 필터 회로로 모델링하여 위의 두 가지 경우에 각각 필터를 설계 및 제작하였으며, 설계 결과와 측정 결과가 잘 일치함을 확인하였다. In this paper, the size of the dual-mode microstrip ring resonator is reduced by adding four open stubs, and bandpass filters having 100 MHz bandwidth are designed at the center frequency of 2 GHz. The size of the ring resonator can be controlled by varying the capacitance of the stubs, and the bandpass filter can be designed in two cases, which are two combinations of the stubs. Two bandpass filters are designed and fabricated by using the two-stage bandpass filter circuit model of the proposed structure, and the measured results show good agreement with the simulated results.

대한민국에서 반려동물을 보유하는 국민은 점차 증가하고 있다. 그 중에서도 개는 오랜 기간 인간과 밀접한 관계를 맺는 종 중 하나이다. 이에 따라 개와 관련된 범죄가 증가하고 있는 추세이다. 본 연구에서는 국내 개(Canis lupus familiaris)의 개체식별에 보다 더 높은 과학적 신뢰도 향상을 위해 감정기법 체계화 및 데이터베이스 구축의 필요성에 부합하여, Canine genotypes panel 2.1 kit(Thermo Fisher Scientific, USA)의 18개 STR(Short tandem repeat) 마커의 다형성 분석을 수행하였다. 다섯 품종(푸들, 시츄, 말티즈, 요크셔 테리어 및 코커 스파니엘)을 비롯한 잡종견 총 300마리를 분석하였다. 분석 결과, 각각의 STR 마커에 대한 관측 이형 접합도 (Hobs)는 0.670 (0.353-0.883), 기대 이형접합도(Hexp)는 0.774 (0.453-0.959), 그리고 다형성 정보 지수는 0.743 (0.391-0.956)으로 각각 나타났다. 부권부정율 (NE-PP)은 1.88E-15, 동일 개체 출현율 (NE-I)은 9.42E-24로 나타났다. 주성분분석을 하였을 때 18개 STR 마커는 5 품종의 개들 중 4 개의 그룹으로 분류하였다. 이 연구로 18개 마커는 개체식별을 위한 감정기법 및 데이터베이스 구축에 충분히 사용이 적합하다고 판단된다. In Korea, the number of pet-bearing people is increasing. Among them, dogs are one of the species that have been closely related to humans. Accordingly, the number of dogs related to crime is also increasing. In this study, polymorphism analysis of 18 STR markers in Canine genotypes panel 2.1 kit(Thermo Fisher Scientific, USA) was performed according to the necessity of systemizing Canis lupus familiaris analytical techniques and constructing a database to improve scientific reliability. A total of 300 were analyzed, including five breeds (Poodle, Sichu, Maltese, Yorkshire Terrier and Cocker Spaniel) and hybrid dogs. Overall, 0.670 (0.353-0.883) Observed heterozygosity (Hobs), 0.774 (0.453-0.959) expected heterozygosity (Hexp) and 0.743 (0.391-0.956) Polymorphism Information Content (PIC) were appeared in each STR. Additionally, 1.88E-15 non-exclusion probability for a candidate parent pair (NE-PP) and 9.42E-24 non-exclusion probability for identity of two unrelated individuals (NE-I) were shown. In accordance with Principal Coordinates Analysis (PCoA), the 18 STR markers were classified into 4 groups of 5 dogs. Therefore, we can foresee this study proves the Canine genotypes panel 2.1 kit is analytical techniques for identifying individuals.
