Purpose: The purpose of this study was to conduct a systematic review to investigate the socio-economic benefits of the poison control center (PCC) and to assess whether telephone counseling at the poison control center affects the frequency of emergency room visits, hospitalization, and length of stay of patients with acute poisoning. Methods: The authors conducted a medical literature search of the PubMed, EMBASE, and Cochrane Library databases. Two reviewers evaluated the abstracts for eligibility, extracted the data, and assessed the study quality using a standardized tool. Key results such as the cost-benefit ratio, hospital stay days, unnecessary emergency room visits or hospitalizations, and reduced hospital charges were extracted from the studies. When meta-analysis was possible, it was performed using RevMan software (RevMan version 5.4). Results: Among 299 non-duplicated studies, 19 were relevant to the study questions. The cost-benefit ratios of PCC showed a wide range from 0.76 to 36 (average 6.8) according to the level of the medical expense of each country and whether the study included intentional poisoning. PCC reduced unnecessary visits to healthcare facilities. PCC consultation shortened the length of hospital stay by 1.82 (95% CI, 1.07-2.57) days. Conclusion: The systematic review and meta-analysis support the hypothesis that the PCC operation is cost-beneficial. However, when implementing the PCC concept in Korea in the future, it is necessary to prepare an institutional framework to ensure a costeffective model.

본 연구에서는 LANDSAT 8호, KOMPSAT 2호 위성영상과 1/25,000 수치지형도를 기반으로 작성된 음영기복도를 이용하여 2007년 1월 20일 오대산 지역에서 발생한 약 4.8의 중규모 지진과 선구조선의 관계를 분석하였다. 대부분의 선행연구는 지체구조와 관련된 선구조선 분석 연구를 하였으며, 주로 2차원의 위성영상과 음영기복도를 활용하였기에 지형의 기복 등에 대한 판독이 어려워 선구조선 추출이 제한적이었다. 본 연구에서는 이를 보완하기 위해 수치표고모델(Digital Elevation Model; DEM)을 기반으로 작성한 3차원 입체 영상과 수계망 분석을 통해 지형의 기복, 수계의 연결성 등을 판독해 선구조선을 추출하여, 2차원 영상에서 나타나는 시각적인 판독에 의한 오류를 최소화한 선구조선 판독도를 작성하였다. 또한 진앙에 대한 선구조선의 통계 요소별 밀도를 추정하기 위해 spline 내삽법을 이용하여 선구조선의 빈도, 교차점, 길이에 대한 밀도를 계산하였다. 그리고 진앙에서의 선구조선 밀도가 얼마나 밀집되어 있는지 정량적으로 표현하기 위하여 각 격자 내의 선구조선 밀도에 대해 최대 선구조선 밀도로 나누는 상대밀도 값(Value of the Relative Density; VRD)을 계산하는 알고리즘을 개발하여 밀도도(density map)를 작성하였다. 각 영상의 진앙에서의 VRD는 최소 약 0.60에서 최대 약 0.90으로 나타났지만, 각 영상별 광원의 고도각과 방위각이 차이가 있어 영상별 VRD보다 통계 요소별 VRD의 평균치를 사용하였다. 그 결과, 빈도의 평균 VRD는 약 0.85로 교차점과 길이의 평균 VRD보다 약 21% 높게 나타나, 선구조선의 빈도 요소가 진앙의 위치와의 관계가 가장 밀접함을 확인하였다. 이와 같이 3차원 영상의 선구조선 추출을 통한 밀도 분석 기술은 향후 지진 발생 가능 지역 분석에 기초자료로써의 의미가 있을 것으로 기대된다.

The acoustical response of fish depends on size and physical structure na, most important, on the presence or absence of a swimbladder. Acoustic scattering models for swimbladdered fish represent a fish by an ideal pressure-release surface having the size and shape as the swimbladder. Target strength experiments of red seabream (Chrysophrys major) have been conducted using 38 (split-beam), 120 (split-beam) and 200kHz (dual-beam) frequencies. At each start of each experiment, the live fish are placed in the cage at the surface, then the cage is lowed to about $4{\cal}m$ depth where it remains during the measurements. To test the acoustic models, predictions of target strength based on swimbladder morphometries of 10 red seabream offish total length from $103{\cal}mm{\;}to{\;}349{\cal}mm$ ($3 <$TL/\lambda$ < 45)are compared with conventional target strength measurements on the same, shock-frozen immediately after caged experiments. X-ray was projected along dorsal aspect to know the morphological construction of swimbladder. and fish body. At high frequencies, Helmholtz-kirchhoff(HK) approximation would greatly enhance swimbladdered fish modeling. Sound scattering model [HK-ray approximation model] for comparison to experimental target strength data was used to model backscatter measurements from individual fish. The scattering data can be used in the inverse method along with multiple frequency sonar systems to investigate the adequacy of classification and identification of fish

Purpose: The purpose of this descriptive study was to assess levels of stress, coping style, and nursing needs for hospitalized pregnant women diagnosed with preterm labor. Methods: Data were collected from 125 pregnant women aged between 20 and 40 years and diagnosed with preterm labor by OBGY units at 3 hospitals. Data were analyzed by frequency, percentage, t-test, and ANOVA with $Scheff{\acute{e}}$ test. Results: The level of stress among women was an average of 2.13 out of 4 points, the level of coping style was an average of 2.66, and nursing needs was an average of 2.83 out of 4 points. The level of stress was significantly different by job, length of hospital stay, type of hospital, and history of admission at obstetric unit. The level of coping style was significantly different by age and monthly income. The level of nursing needs was significantly different by type of hospital. Higher level of stress and coping style were related to higher level of nursing needs. There was no significant correlation between stress and coping style. Conclusion: The result showed the importance of nursing intervention dealing with stress, coping style and nursing needs for women with preterm labor. Nurses need to provide nursing interventions to reduce the stress, to strengthen the coping style, and to satisfy the nursing needs for pregnant women hospitalized due to preterm labor.

Purpose. With a sample of cognitively impaired nursing home residents and nursing staff, the following were examined 1) the proportion and nature of aggressive behavior, 2) the frequency and types of aggressive behavior, 3) the difference between the residents who demonstrate aggressive behavior and those who do not demonstrate aggressive behavior (age, mental status, functional status, and pain, length of nursing home stay), and 4) nursing staff responses to aggressive behavior by residents. Methods. A cross-sectional descriptive study design was used. Data were collected from cognitively impaired nursing home residents (N=205) and nursing staff (N=60) at two nursing homes using Ryden Aggression Scale I and II, Mini-Mental State Exam, Modified Barthel Index, Verbal Descriptor Scale, and aggressive behavior management questionnaire. Data were analyzed using descriptive statistics including t-test. Results. About $62.9\%$ residents were found to be aggressive and $38.5\%$ were both physically and verbally aggressive. Pushing, making threatening gestures, hitting, slapping, cursing/obscene/vulgar languages, making verbal threats were occurred frequently. Aggressive residents were significantly older, had more cognitive impairment, had more pain, and stayed longer in the nursing home when compared with non-aggressive residents. Considerable proportion of nursing staff responded to aggressive behaviors inadequately. Conclusion. Aggressive behavior among cognitively impaired nursing home residents is prevalent thus needs to be prevented and reduced. Along with environmental modification, educational programs for nursing staff and family caregivers need to be developed and implemented so that they can have extensive knowledge and skills to manage aggressive behaviors.

This study was conducted for silver generation women, age 60 and more. Questionnaire was answered by the total 291 of women. Frequency analysis, t-test, ANOVA and Duncon-Test have been completed by using SPSS 12.0 tool. The conclusion of the study is below. First, silver generation women live in Seoul and South Gyeongsang Province. The data shows huge academic background gab among regions. Second, the following is the preferences found by 15 stimulants which expert groups identified based on demography. People in South Gyeongsang Province like default, tailored, three-button jacket more. People in South Gyeongsang Province prefer to Chanel jackets and people in their 70s prefer to it than in 60s, stand collar casual jacket for color and material, and the less they are educated, the more they like the jackets. And those who have less personal expenses tend to prefer to it. South Gyeongsang Province shows preference for semi polo-neck sweater. Highly educated did not show any preference for it. Women in their 70s tend to like blouses with round neckline. The data shows there is significant difference of preference for design, color and material for coloration vest between education levels. The less educated tends to like it. People in South Gyeongsang Province and those who live with their children are in favor with half sleeve jackets for colors and materials. All in Seoul and South Gyeongsang Province do not like three-quarter-length sleeve jackets because those jacket have wide and deep plunging neckline. The study showed people living in Seoul, in their 60s, highly-educated tend to favor polo shirts significantly. Seoul favor basic straight pants and people with any level of education excluding elementary prefer to it. The highly-educated and those who have a bigger allowance tend not to prefer to baggy trousers. In conclusion, Fifteen incentives (clothing design) for semi polo-neck sweaters, polo t-shirts, basic straight pants are more proper to silver generation women in their 60s, living in Seoul. Other designs are desirably applicable to customers on a national scale at middle prices.
