The negative pressure distribution curves of the exit of printing nip were obtained by the transducer type tackometer. As the results, found that the elasticity of rubber rollers and pastic viscosity affect to the maximum negative and positive pressure but, the gap of the printing nip didn`t affects to the tack values of ink and ink film thickness. Ink spritting is accured by negative pressure and inks viscoelasticity. And the tack value is affect by properties of the vehicle component in the inks.

정전 탐침을 이용하여 유도 결합형 반응기에서 발생하는 산소 플라즈마의 음이온 발생 특성을 관찰하였다. 입력전력과 운전압력 조건에 따른 산소 플라즈마에서 electronegative 음이온 플라즈마의 입력전력과 운전압력에 따른 정전 탐침에 흐르는 포화 양 전류 대 포화 음 전류(전자 전류와 음 이온 전류의 합)의 전류 비율과 플라즈마 부유 전위와 플라즈마 전위 차의 변화로부터 음이온 발생 특성관찰을 하였다. 전류비의 증가와 전위차 값의 감소는 입력전력이 증가함에 따라 약 30∼60 mTorr 운전압력 영역에서 나타났으며 이 조건에서 음이온의 발생량이 증가함을 의미하고, 플라즈마내의 이온들은 음이온과 재결합에 의한 손실이 증가하여 플라즈마 밀도가 감소함을 알 수 있었다.

Background/Objective: The aim of this study was to perform a comparative evaluation of the yields of conventional brush cytology and brush cytology with negative pressure in the diagnosis of malignant biliary strictures. Methods: A total of 132 consecutive patients undergoing endoscopic were identified. Of these, 88.0 had brush cytology after ERCP and 44 were Brush cytology with negative pressure. Retrograde cholangiopancreatography (ERCP) including brush cytology and brush cytology with negative pressure in patients with biliary strictures between 2012-2015. Endoscopic retrograde cholangiography was performed with a standard videoduodenoscope Olympus TFJ 160-R (Olympus, Hamburg, Germany) and brush cytology with a Cook medical Double Lumen Biliary BrushTM (Cytology). Means and standard frequencies were used to calculate variables. Results: Positive results for malignancy were obtained in 22 of 88 patients (25%) by brush cytology and 31 of 44 patients (70.4 %) by brush cytology with negative pressure. Conclusions: Sensitivity of cytology sampling could be maximized by negative pressure during ERCP.

Background: To determine the correlation Between forward head posture and plantar pressor in a McKenzie Exercise. Methods: This study had a cross-sectional design. There are included 20 participants with forward head posture. We measured the craniovertebral angle (CVA), cranial rotation angle (CRA) by image obtained digital camera and the plantar pressure, static balance using Gait Analyzer each before and after McKenzie Exercise. Results: There was negative correlation between CVA and CRA (p<.05). There was negative correlation between CVA and fore foot(p<.05). There was positive correlation between CRA and both fore foot (p<.05). There was negative correlation between CVA and static balance(p<.05). There was positive correlation between CRA and static balance (p<.05). Conclusions: There is a correlation between the change a mount of forward head position and plantar pressure in the McKenzie Exercise.

The purpose of this study was to examine the health status of the daughter and daughter- in-law caregivers who care for a cognitively and/or functionally impaired elderly, individual to identify factors that were related to reported health outcomes, and to investigate the negative and positive impacts of family caregiving. Data was collected from 120 daughter and daughter-in-law caregivers and care-recipients using face to face interviews. Most caregivers were daughters- in-law (77.5%) and most care-recipients were female (88.3%). Sixty-eight percent (n=81) of caregivers reported depressive symptomatology. General health also deteriorated by caregiving. Caregivers reported several negative impacts (difficulties): care-recipients' problematic behaviors, deterioration of their own health, pressure from social norms related to family caregiving in Korea, intrafamily conflict, and economic problems. Contrary to the popular belief, caregivers reported diverse positive impacts of family caregiving (68.3%): a sense of filial responsibilities, recognition from elderly, family members, relatives, and society, education for the children, and familial harmony. Higher depression score was predicted by lower family income, the presence of cognitive impairment of care-recipients, and higher level of social conflict of caregivers. Poor general health of caregivers was predicted by older caregivers' age, lower competing roles of caregivers, and poor emotional health. While not seeking to deny the negative aspects of family caregiving, it is also necessary to understand positive aspects of family caregiving to see complete picture of caring for an elderly family member.

Objectives: The aim of this study was to evaluate the apical pressure generated by 2 endodontic irrigation needles and the GentleWave system in mandibular molars. Materials and Methods: The mesial and distal root canals of 12 mandibular molars were irrigated with a 30-gauge close-end needle or with a 30-gauge open-end needle. Procedures were performed in the mesial and distal canals. The GentleWave procedure and irrigation at 1 mm from the apex in the distal roots using an open-end needle were used, respectively, as negative and positive controls. The apical pressure was measured using a data acquisition pressure setup. Apical pressure exerted by the different needles in the 2 different canal types was statistically compared using 2-way analysis of variance. Results: Significant differences were found in the apical pressure for both needles and the canal type. The lowest values were obtained with close-end needles and in mesial canals. Negative apical pressure values were obtained using GentleWave. Conclusions: The needle and the canal type influenced the apical pressure. The GentleWave procedure produced negative apical pressure.

Purpose : This study aimed to identify the factors affecting coronavirus disease 2019 (COVID-19) infection control practices of nurses in negative pressure isolation rooms. Methods : The participants were 150 nurses working in three hospitals with negative pressure isolation rooms. Data were collected using structured questionnaires and analyzed using an independent t-test, one-way ANOVA, Scheffé test, Pearson correlation coefficients, and multiple regression analysis using the SPSS/WIN 26.0 program. Results : Factors significantly influencing the subject's COVID-19 infection control practice include Being married (𝛽=.18, p =.016), working in a ward with negative pressure isolation rooms (𝛽=.44, p <.001), working in an ICU with negative pressure isolation rooms (𝛽=.27, p =.010), COVID-19 infection control attitude (𝛽=.28, p =.001), anxiety for COVID-19 (𝛽=.30, p <.001). The explanatory power of these variables for COVID-19 infection control practice was 24.6% (F=8.67, p <.001). Conclusion : It is expected that strategies that utilize positive attitudes which believe that COVID-19 disease may be overcome by COVID-19 infection control practice will help improve emerging infectious diseases infection control practice.

This study was done to investigate the blood pressure, BMI and serum lipids of cerebrovascular accident patients in Seoul. The subjects were 195 Korean urban cerebrovascular accident patients who were hospitalized at Dong Seo Oriental Hospital in Seoul from June, 1997 to December, 1997. There were more cerebral infarction patients(164) than cerebral hemorrhage patients(31). Cerebral infraction patients were prevalent for subjects in their sixties, but cerebral hemorrhage patients were most commonly in their fifties. The BMI of cerebral infarction accidents was significantly higher than that of cerebral hemorrhage patients(p<0.05). Mean diastolic blood pressure of cerebral hemorrhage patients was significantly higher than that of the cerebral infarction patients(p<0.05). The mean systolic blood pressure of the cerebral hemorrhage patients was higher than that of the cerebral infarction patients, not statistically significant. The serum total cholesterol and glucose levels of the cerebral infarction patients was significantly higher than those of the cerebral hemorrhage patients(p<0.05). Serum total cholesterol(p<0.01), triglyceride(p<0.05) and LDH(p<0.01) levels of female subjects were significantly higher than those of male subjects. Serum total cholesterol has a negative correlation with serum GOT and GPT, but has a positive correlation with triglyceride. Serum triglyceride has a negative correlation with diastolic blood pressure but has a positive compellation with serum glucose.
