P파와 S파의 도착시간 정보는 지진 발생위치 결정, 1차원 및 3차원 지하구조 등 지진학 연구 수행에 중요한 정보이다. 최근 지진관측소의 수가 비약적으로 증가함에 따라 관측망을 운영하면서 수동으로 지진파의 도착시간을 측정하는 것은 상당한 시간이 소요되는 일이 되었다. 본 연구에서는 진원요소에 대한 사전정보(지진 발생위치와 시간)를 확보할 수 있는 경우 Akaike Information Criterion (AIC)을 적용하여 추가의 관측소에서 국지지진의 P파와 S파의 도착시간을 자동측정하였다. 해당 방법을 경산(DAG2) 지진관측소에 기록된 자료에 적용한 후 수동 측정한 값과 자동 측정한 값을 비교한 결과 P파의 경우 95.1%, S파의 경우 93.7%가 0.1초 이하의 차이를 보이면서 결정되는 것을 확인하였다. 자동측정결과의 높은 정확성은 향후 고밀도 지진관측망 운영에 성공적으로 적용될 수 있음을 시사한다.

Purpose: The purpose of this study was to examine the recognition of achievement and importance of nursing program outcome among nursing students. Methods: The survey was performed with 439 nursing student and recruited from 3-year or 4-year nursing students, scheduled to graduate from university. The data was collected by questionnaires and was analyzed with SPSS statistics 19.0. Results: The achievement of nursing program outcome was 3.28. and the important of that was 4.38. The achievement of nursing program outcome on critical thinking and communication of 4-year nursing students were higher than 3-year nursing students. Achievement of program outcome were significantly different according to satisfaction of curriculum, club activity and voluntary activity. Conclusion: These findings indicate that outcome-based nursing curriculum is need to consider the importance and achievement level of program outcome for nursing students.

본 연구에서는 도시계획결정 이후 예산등의 이유로 장기간 집행되지 않은 도시계획 도로시설의 가시적인 관리 및 활용에 있어 참고자료의 하나로서 Google Earth 영상을 이용하였다. 연구 대상지의 Google Earth 영상을 취득하여 미집행 시설을 추적한 결과, 실제의 토지이용현황을 구체적으로 반영함과 동시에 시간과 경제적 비용을 절약할 수 있는 추적방법으로 평가 되었다. 향후 미집행 시설의 관리나 집행 시 기초적인 참고자료로 활용할 수 있을 것으로 판단된다.

A portable count-ratemeter and a thermoluminescent detector ($CaSO_4:Dy$) have been used to obtain total gamma dose rates at approximately 50 locations during the course of several survey trips in the southeastern Korea. The purposes of these measurement were to provide a future reference data and to establish the approximate range of population exposure to the natural environmental radiation. The natural levels encountered ranged from a low of 14.6 microroentgen per hour to a high of 18.9 microroentgen per hour with a mean of $16.3{\pm}1.0$ microroentgen per hour. Among these results are the relatively high natural dose rate levels in the Masan area and Yangsan-Tongdosa area with the relatively low natural dose rate levels in the Gyeongsan-Cheongdo area and the Samrangjin-Jinyeong-Gimhae area.

We investigated whether nitric oxide (NO) may serve a role in bladder function by immunohistochemical analysis of the distribution of intrinsic NADPH-diaphorase and functional study of isometric tension recordings via a photo-induced adequate nitric oxide (PIANO) generating system using rat bladder. Results suggest that a small number of NADPH-diaphorase-positive perikarya are present within the bladder wall and within adjacent small ganglia. Furthermore, NADPH-diaphorase-positive nerve fibers were observed in the adventitial and muscular layers, subjacent to the urothelium and perivascular fibers. Rat bladder strips precontracted with 3$\mu$M carbachol were reversibly relaxed upon NO generation by UV irradiation. PIANO-mediated relaxation was sensitive to oxygen free radicals. In addition, tissue cGMP levels were increased by the PIANO generating system and elevated cGMP levels were decreased by pretreatment of guanylate cyclase inhibitor, methylene blue. These results indicate that NO may serve a role in modulating bladder tone in the rat.

We report twenty eight ichneumonid species new to Korea. These species belong to seven subfamilies. Among them five subfamilies, Diacritinae Townes, 1965, Microleptinae Townes, 1958, Orthocentrinae F$\ddot{o} $rster, 1869, Orthopelmatinae Schmiedeknecht, 1910, Phrudinae Townes and Townes, 1949, are newly introduced to Korean fauna. All specimens are based on the insect collection of animal systematic laboratory at the Yeungnam University Gyeongsan Campus. Photographs of habitus of newly recorded subfamilies, diagnosis of 28 species and host information are provided.

Based on the cardiac PACS application collected from three university hospitals across the country, this research showed us a composition method of a server and storage devices with conditions in the field. Also, we founded the practical use of software making the best of cardiovascular PACS features. In addition, it also examined the components and requirements of the key functions that are available in the cardiovascular sector. We will be investigated the design experience and applications on stable storage and transmission of large video clip data, cardiovascular analysis, and gear interlocks through the study.

This paper is concerned with the life-cycle cost(LCC) of the urban transit system which was developed by KRRI and is now under test in Gyeongsan, Korea. Its reliability, availability and maintainability(RAM) were analyzed. LCC is the core part of analyzing the total cost of acquisition and ownership of a system. LCC analysis of a system is the most effective when it is applied in the it's early design phase. In this paper, we present IEC 60300-3-3(Life Cycle Costing) in detail and propose how to apply LCC in assessing the urban transit system according to RAM process. This case study demonstrates that reliability management system is very effective in reducing the operating cost of subway corporations in Korea.
