The purpose of the present study was to examine the effects of somatoform and, psychoform dissociation and hyperarousal on posttraumatic stress symptoms. We also investigated the differences between the two groups in heart rate variability (HRV) under different conditions. The experimental group included 14 individuals who had experienced traumatic events within 3 months. The control group included 14 healthy individuals who were matched for gender and age to the experimental group. All participants were asked to complete a series of self-report questionnaires pre- and post-treatment. Their heart rate variability (HRV) was recorded at baseline, recall, and during the recovery periods (for 5 minutes in each period). The results showed that experimental group reported lower heart rate variability at baseline than the control group. Furthermore, the hierarchical regression analysis indicated that only somatic dissociation contributed significantly to the prediction of posttraumatic stress symptoms among the prediction factors of the present study. Finally, the clinical implications and several limitations of the present study were discussed. 본 연구에서는 신체형 및 심리형 해리와 과각성이 외상 후 스트레스 증상에 미치는 영향력에 대해 살펴보았다. 또한, 실험군과 통제군이 심박변이도(heart rate variability; HRV)의 개별적인 조건 하에서 어떠한 차이를 나타내는지를 검토하였다. 참여자들은 외상사건을 경험한지 3개월 이내인 급성단계의 실험군 14명과 성별과 연령대에 따라 짝진 건강한 통제군 14명이었다. 각 참여자들은 처치 전후에 일련의 자기보고식 질문지를 완성하였다. HRV는 기저선, 회상기 및 회복기에걸쳐 각 5분씩 측정하였다. 실험결과, 기저선에서 실험군은 통제군보다 HRV가 더욱 낮게 활성화되는 양상을 보였다. 게다가, 위계적 회귀분석에서는 본 연구의 예측변인 중 신체형 해리가 외상후 스트레스 증상을 예측하는데 있어 유의하게 기여하는 것으로 나타났다. 마지막으로 본 연구의의의와 제한점, 후속 연구를 위한 제언을 논의하였다.

The Relation between Retention and Turnover Intentionamong Social Workers

홍미진 연세대학교 사회복지연구소 2013 한국사회복지조사연구 Vol.35 No.-

Although prior research has suggested the necessity of investigating retention and turnover separately, retention and turnover are usually treated as one construct, and numerous studies have only focused on turnover. This study examines the relation between retention and turnover intention among social workers based on Herzberg’s motivation theory. A sample of 207 Maryland-chapter NASW social workers are included in the final analysis. A principal components analysis and a correlation test were conducted; the findings indicate that intention to stay and intention to leave are highly correlated each other and are likely to be two ends of one construct. Given the findings of the study, implications for research, theory and practice are discussed.

홍미진,이선영,김정환,성인경,박형석,심찬섭,진춘조 대한의학회 2014 Journal of Korean medical science Vol.29 No.10

Endoscopic hemostasis is the first-line treatment for upper gastrointestinal bleeding (UGIB). Although several factors are known to be risk factors for rebleeding, little is known aboutthe use of antithrombotics. We tried to verify whether the use of antithrombotics affectsrebleeding rate after a successful endoscopic hemostasis for peptic ulcer disease (PUD). UGIB patients who underwent successful endoscopic hemostasis were included. Rebleedingwas diagnosed when the previously treated lesion bled again within 30 days of the initialepisode. Of 522 UGIB patients with PUD, rebleeding occurred in 93 patients (17.8%). Therate of rebleeding was higher with aspirin medication (P = 0.006) and after a longendoscopic hemostasis (P < 0.001). Of all significant variables, procedure time longer than13.5 min was related to the rate of rebleeding (OR, 2.899; 95% CI, 1.768-4.754;P < 0.001) on the logistic regression analysis. The rate of rebleeding after endoscopichemostasis for PUD is higher in the patients after a long endoscopic hemostasis. Endoscopic hemostasis longer than 13.5 min is related to rebleeding after a successfulendoscopic hemostasis for PUD.

Bird strike accidents, a collision between aircraft and birds, have been increasing annually due to an increasing number of aircraft operating each year to meet heavier demand for air traffic. As such, many airports have conducted studies to assess and manage bird strike risks effectively by identifying and ranking bird species that can damage aircraft based on the bird strike records. This study was intended to investigate the bird species that were likely to threaten aircraft and compare and discuss the risk of each species estimated by the single-matrix and multi-matrix risk assessment models based on the Integrated Flight Information Service (IFIS) data collected in Gimpo, Gimhae and Jeju Airports in South Korea from 2005 to 2013. We found that there was a difference in the assessment results between the two models. The single-matrix model estimated 2 species and 6 taxa in Gimpo and Gimhae Airports and 2 species and 5 taxa in Jeju Airport to have the risk score above "high," whereas the multi-matrix model estimated 3 species and 5 taxa in Gimpo Airport, 4 species and 5 taxa in Gimhae Airport, and 2 species and 3 taxa in Jeju Airport to have the risk score above "very high." Although both models estimated the similar high-risk species in Gimpo and Gimhae Airports, there was a significant difference in Jeju Airport. Gimpo and Gimhae Airports are near the estuary of a river, which is an excellent habitat for large and heavy waterbirds. On the other hand, Jeju Airport is near the coast and the city center, and small and light bird species are mostly observed. Since collisions with such species have little effect on aircraft fuselage, the impact of common variables between the two models was small, and the additional variables caused a significant difference between the estimation by the two models. 항공교통 수요 증가로 항공기의 운항이 증가하면서 항공기 동체와 조류가 충돌하는 조류 충돌 사고가 매년 증가하고있다. 이에 각 공항에서는 조류 충돌 사고기록을 바탕으로 항공기에 피해를 줄 것으로 예상되는 조류 종을 파악하고 순위를매겨 충돌 위험을 효과적으로 평가 및 관리할 수 있는 연구를 수행하고 있다. 본 연구는 김포, 김해 및 제주국제공항에서2005년부터 2013년까지 수집된 통합운항정보시스템 (Integrated Flight Information Service, IFIS) 자료를 바탕으로 항공기에 피해를 줄 것으로 예측되는 조류 종을 파악하고, 단일 및 다중 매트릭스 모델 간 위험성 평가 결과를 비교 분석 및고찰하기 위해 수행되었다. 단일 매트릭스 모델을 통한 평가 결과 김포국제공항 및 김해국제공항에서는 왜가리, 독수리 2종과백로류, 기러기류, 오리류, 갈매기류, 비둘기류 및 까마귀류가, 제주국제공항에서는 독수리, 까치 2종과 기러기류, 오리류, 갈매기류, 비둘기류 및 까마귀류가 ‘매우 높음’ 또는 ‘높음’으로 평가되었다. 다중 매트릭스 모델을 통한 평가 결과 김포국제공항에서는 왜가리, 독수리, 까치 3종과 백로류, 기러기류, 오리류, 도요류 및 비둘기류가, 김해국제공항에서는 왜가리, 독수리, 찌르레기, 까치 4종과 백로류, 기러기류, 오리류, 도요류 및 비둘기류가, 제주국제공항에서는 왜가리, 까치 2종과 오리류, 도요류, 비둘기류가 ‘매우 심각’ 또는 ‘매우 높음’으로 평가되었다. 모델 간 예측 결과에 있어 김포국제공항과 김해국제공항은차이가 없었으나, 제주국제공항은 유의한 차이가 있었다. 이는 김포와 김해국제공항은 모두 하천의 하류에 위치하고 있어대형 수조류들이 주로 관찰된 것에 반해 제주국제공항은 바다와 도심에 가까이 위치하고 있어 몸무게가 작은 소형 조류들이많이 관찰되었기 때문이다. 이러한 종들과의 충돌이 항공기 동체에 미치는 영향이 적어 모델 간의 공통된 변수의 영향은적었고, 추가적인 변수에 의해 두 모델의 평가 결과 간 큰 차이가 발생한 것으로 판단된다.

Black-tailed gulls, Larus crassirostris, have been known as resident birds in Korea, but their wintering and breeding habitat ranges were little known about. We investigated the habitat ranges of Blacktailed gulls breeding on Dokdo Island - which is the eastern end of their breeding colonies in Korea. Three adult Black-tailed gulls were fitted with Global Positioning System data loggers in May 2018 and their positions were tracked for 9 days, 245 days and 365 days each respectively. Black-tailed gulls stayed on Dokdo Island until June for breeding purposes and moved down to the southern part of Japan for wintering. The following year, a Black-tailed gull started to move northward in February and returned to Dokdo Island in April. They traveled a total of 207,334−229,507 km2 (MCP) throughout a whole year. Based on location density categories accounting for 50% of locations, they used 3,618 to 3,803 km2 in area. Black-tailed gulls breeding on Dokdo Island used smaller habitat ranges during the wintering period than the other periods. This is the first report on the habitat ranges of Black-tailed gulls breeding on Dokdo Island.

Because South Korea is located on the East Asian-Australian Flyway, it is important phenologically as a stopover site for a variety of migratory birds that travel long distances between breeding and wintering grounds. In addition, uninhabited islands along the coast are used for breeding by various waterbirds, which frequently go on foraging trips to feed offspring. For these reasons, as birds may collide with offshore wind farms while flying, or be disturbed during the construction or operation of wind farms, we discussed in this study the necessity of bird monitoring that should occur before the construction of offshore wind farms to minimize potential impacts on birds and help to locate proper construction sites. Monitoring methods were classified into bird diversity survey, spatial distribution survey and migration survey, and each can be divided into aerial, ship-based and land-based surveys according to survey location and means. In the migration survey, trackers and radar can be used for accurate and detailed data collection. Basically, the point census method and line transect method can both be used for monitoring and bird species, number of individuals, observation location and time should be recorded. The data collected from bird monitoring can be used as the basis for the site selection of wind farms.

Cerebral palsy is a group of permanent disorders of the development of movement and posture, causing activity limitations. This study aimed to investigate how Pilates exercises immediately affect standing balance and walking in children and adolescents with spastic cerebral palsy. We included 8 participants aged 7∼18 years with spastic cerebral palsy. We administered the Pilates exercise for 60 minutes. We used the Timed Up and Go (TUG) test, balance plate, and gait analysis to evaluate balance function and gait pattern before and after the intervention. Comparison of the average values of all measured variables before and after therapy showed a statistically significant difference (p<.05) after therapy. There were significant differences in TUG test, balance function, gait speed, and cadence before and after pilates exercise. Pilates exercise is immediately effective in improving standing balance and gait function in children and adolescents with spastic cerebral palsy.

Objective To determine the possibility of a new measurement tool using electromyography and ultrasonography for quantitative spasticity assessment in post-stroke patients. Methods Eight hemiplegic stroke patients with ankle plantarflexor spasticity confirmed by a Modified Ashworth Scale (MAS) were enrolled. Spasticity was evaluated using the MAS and Modified Tardieu Scale (MTS). Each subject underwent surface electromyography (sEMG) using the Brain Motor Control Assessment (BMCA) protocol and was compared with a healthy control group. Using ultrasonography, muscle architecture and elasticity index were measured from the medial gastrocnemius muscle (GCM) on the affected and unaffected sides. Results MAS and MTS revealed significant correlation with sEMG activity. The fascicle length and pennation angle were significantly decreased in the medial GCM on the hemiplegic side compared with the unaffected side. The elasticity index of the spastic medial GCM was significantly increased compared with the unaffected side. The MTS X and R2–R1 values were significantly correlated with the elasticity index in the hemiplegic GCM. The relationship between clinical evaluation tools and both BMCA and sonoelastography was linear, but not statistically significant in the multiple regression analysis. Conclusion The BMCA protocol and ultrasonographic evaluation provide objective assessment of post-stroke spasticity. Further studies are necessary to conduct accurate assessment and treatment of spasticity.

홍미진,황다현 대한의생명과학회 2022 Biomedical Science Letters Vol.28 No.1

The imbalance of oxidative stress due to the excessive production of reactive oxygen species (ROS) leads to the pathogenesis of liver disease. To prevent this, the role of antioxidant mechanisms is important. Antioxidant studies have been reported on the Filipendula glaberrima Nakai. However, studies applied to HepG2 cells, which are human liver cells, have not yet been conducted. In this study, 70% ethanol extract of Filipendula glaberrima Nakai (FGE) was prepared and antioxidant activity was investigated. It was confirmed whether FGE pretreatment could reduce hydrogen peroxideinduced oxidative stress in HepG2 cells. The increase in gene expression of antioxidant biomarkers and the scavenging ability of ROS were measured, and Hoechst 33342 staining was used to know the inhibitory effect of the apoptosis. As a result, FGE significantly increased SOD (2.6-fold), CAT (4.4-fold), MT-1A (3.1-fold), GPx (4-fold), and G6PD (2.4)- fold compared to the H2O2-treated group. FGE directly inhibited ROS production from 13.4 to 3.6 (the fluorescence mean of DCF-DA) and also reduced apoptotic cells from 45% to 10% (Hoechst 33342 staining) at 2.5 μg/mL. These results demonstrate the excellent antioxidant activity of FGE and show that it can be used as a functional food to prevent liver disease.
