유희정 한국농공학회 1983 한국농공학회논문집 Vol.25 No.4
In order to study the disaster of typhoons which hit the Korean peninsula a period of 22 years from 1959 through 1980 was covered to collect necessary data with respect to attack of typhoons and their damage. Centering around the Korean peninsula, typhoons which attacked between 1959 and 1980 were grouped according to their treking routes and damage for detailed analyses. The results are summarized as follows: 1. The average annual damage of typhoons in the Korean peninsula was found to be 1.27 from June to September. The monthly distributions were found to be 53.6% in August, 28.6% in September and 14.2% in July. 2. About an half (56.4%) of the typhoons which hit the Korean peninsula passed through the western coast and 27.3% through the southern and 14.6% through the eastern. Typhoons of the we8tern coast were divided by their treking routes as 25.5% in CWE type (Jul., Aug., Sep.), 14.6% in WE type (Jul., Aug.), 16.3% in W type (Jul.). 3. The minimum SLP averaged 976.6mb and ordere:l by the treking routes as E<S <WE<W$_1$<CWE. In the group average SLP, W$_1$ and CWE types are higher 20mb than S, E or WE types. 4. The Korean peninsula was damaged by all number of the typhoons in WE or S type, by a third at number of its in E or WE and WI type. 5. The annual probabilities of typhoon-disasters were 0.773 for once or more, 0. 409 for twice or more, and 0.091 for three times or more. Hearvy damage experienced in the Korean peninsula are found to have an annual. 6. Amount of the damage by the treking routes in ordered S>WE>CWE>E>W$_1$, and heavy storms experienced in the Xorean peninsula are found to have accompanied the WE and S types during the months of August and September. 7. The average annual damages were found to be 110 at the death-tall, 45, 000 at the sufferers and 10.5 billion at the property damage. 8. Seventy-sex percent of the all damage in the Korean peninsula distributed on the district from the 36th Parallel south and included Chie Ju island.
Regularized Zero-Forcing Beam Design under Time-Varying Channels
유희정,김태준 한국전자통신연구원 2016 ETRI Journal Vol.38 No.3
In this paper, an efficient beam tracking algorithm for a regularized zero-forcing (RZF) approach in slowly fading multiple-input and single-output (MISO) broadcast channels is considered. By modifying an RZF equation, an RZF beam tracking algorithm is proposed using matrix perturbation theory. The proposed algorithm utilizes both beams from the previous time step and channel difference (between the previous and current time steps) to calculate the RZF beams. The tracking performance of the proposed algorithm is analyzed in terms of the mean square error (MSE) between a tracking approach and an exact recomputing approach, and in terms of the additional MSE caused by the beam tracking error at the receiver. Numerical results show that the proposed algorithm has almost the same performance as the exact recomputing approach in terms of the sum rate.
일선공무원의 시민신뢰가 시민참여 수용성에 미치는 영향: 정책과정 및 유형별 시민참여 필요성의 조절효과를 중심으로
유희정,이숙종 한국행정학회 2015 韓國行政學報 Vol.49 No.1
본 연구는 인식조사를 통해 일선공무원의 시민신뢰와 시민참여 수용성을 측정하고, 두 변수들 간의 영향관계에 있어서 정책과정 및 유형별 시민참여 필요성의 조절효과를 분석하였다. 그 결과를 요약하면 다음과 같다. 첫째, 공무원의 시민신뢰를 시민참여에 따른 위험감수, 시민의견에 대한 순응, 시민협조에 대한 믿음의 개념구성 요소 별로 측정하였는데, 그 결과 대부분 ``보통``에 근접하는 것으로 나타났다. 둘째, 독립변수들 중에서는 시민참여에 따른 위험감수와 시민협조에 대한 믿음이 시민참여 수용성과 통계적으로 유의미한 정(+)의 영향관계를 형성하는 것으로 발견되었다. 셋째, 시민참여 수용성에 대한 조절변수의 주효과를 분석한 결과, 정책결정 및 평가단계에의 시민참여 필요성을 높게 인식할수록 그리고 분배정책과 재분배정책에의 시민참여 필요성을 높게 인식할수록, 시민을 행정에 관여시키려는 의지가 강한 것으로 확인되었다. 다음으로 공무원이 정책과정 및 유형별로 인식하는 시민참여의 필요성은 위험감수와 순응이 시민참여 수용성에 미치는 정(+)의 영향을 조절하는 것으로 나타났다. 이와 같은 결과는 정책과정별로 시민과의 상호작용을 통해 형성되는 공무원의 인식이 참여행정 구현에 있어서 중요하고, 시민참여를 꾀하도록 명시하는 제도적 내용이 정책유형별로 개선 및 보완되어야 할 필요가 있음을 시사한다.
