Objectives : The purpose of this study was to explore comparison of clinical characteristics among Anxiety disorder, Depressive disorder, and Co-morbid of Anxiety disorder and Depressive disorder. Methods : Since January, 2017 to May, 2019, patients were recruited from the department of psychiatry of Hanyang University Guri Hospital. Participants were diagnosed Anxiety disorder, Depressive disorder, and Co-morbid of Anxiety disorder and Depressive disorder using DSM-5 criteria by board certified psychiatrists or clinical psychologists. And each of participants tested with MMPI-2 and clinical psychologists were converted MMPI-2 to MMPI-2-RF. The data were analyzed using SPSS 18.0. Results : The results indicated EID, RC2, HLP, SAV, and INTR-r were the highest in Co-morbid of Anxiety disorder and Depressive disorder group. And BXD, RC4, JCP, and AGGR-r were the highest in Depressive disorder group. Conclusions : The results indicated that Co-morbid of Anxiety disorder and Depressive disorder group were more severe internalizing dysfunction like lower positive emotion, helplessness, social avoidance and discomfort than single-diagnosed group. Single Depressive disorder group were more serious externalizing dysfunction like anger and aggression than single Anxiety disorder and Co-morbid of Anxiety disorder and Depressive disorder. The implications and limitations were discussed.

This study investigates the socio-economic and clinical characteristics associated with emergency medical transport use by the elderly based on 2008~2011 Korea Health Panel data. A model of emergency medical transport use was analyzed, and the results indicate that use of 119 ambulances and private ambulances by the elderly accounted for 46.8% of all users, and 35.1% of their emergency room visits. Statistically significant factors associated with emergency medical transport use were gender (OR = 2.19, 95% CI = 1.51-3.17), relationship to household (OR = 2.19, 95% CI = 1.45-3.32), insurance type (OR = 1.41, 95% CI = 1.10-1.82), handicap (OR = 1.44, 95% CI = 1.14-1.83), reason for emergency department visits (OR = 1.53, 95% CI = 1.20-1.97), and treatment after emergency medical service completed (OR = 3.45, 95% CI = 2.80-4.25). The increased elderly population in an aging society will lead to a surge in demand for emergency patient transport services, and emergency medical services that are tailored to the elderly need to be developed accordingly.

최근, 새로운 전자재료로서 GaN 분말의 합성과 응용에 관한 연구가 많이 이루어지고 있다. CaN 분말은 열처리 과정 중 분해를 방지하기 위한 표면 보호용 소재, CaN 박막 또는 벌크 결정을 성장하기 위한 precursor 및 대면적 평판표시소자 제작을 위한 전기발광소자용 소재 등에 적용되고 있다. 일반적으로 100$0^{\circ}C$ 이상의 온도에서Ga과 NH$_3$를 반응시키거나, Ga이 포함된 화합물반도체 또는 산화물 및 질산염 등을 NH$_3$ 분위기에서 가열시켜 GaN 분말을 합성시키고 있다. 본 논문에서는 출발물질로서 GaOOH를 채택하고, 이를 NH$_3$ 가스를 흘리면서 가열 반응시켜 GaN 분말을 합성하고 X선 회절분석 방법을 사용하여 GaN의 합성에 대한 반응기구를 조사하였다. GaN 분말을 합성하기 위하여 GaOOH 분말 1g을 석영 용기에 담아 석영 반응관 내에 위치시키고, 반응관 내부를 $10^{-3}$ torr의 진공으로 배기한 후 $N_2$를 주입하면서 전기로의 온도를 1$0^{\circ}C$/min으로 승온시켰다. 반응온도는 300~l17$0^{\circ}C$의 범위에서 변화시켰고, 반응시간은 10분부터 24시간까지 변화시켰으며, NH$_3$의 유량은 300~700 sccm의 범위에서 변화시켰다. GaN의 반응역학을 조사하기 위하여 X선 회절도에서 특정 성분의 회절강도는 시료 내에 포함된 특정 성분의 량에 직접 비례한다고 가정하고, 2$\theta$=37$^{\circ}$부근에서 관찰되는 GaN의 (101)면에 의한 회절강도를 측정하고, 이를 GaN의 생성량으로 고려하였다.}C$로 소결 하였다. coating 결과 박리현상은 없었으나, 표면과 단면의 SEM분석결과 다소 porous한 박막층이 형성되었으며, Ca이온이 지지체로 permeation되는 현상이 발생하였다. 이와 같은 결과로부터 보다 치밀한 박막생성을 위해, slurry 제조조건을 변화시켰으며, Ca이온의 migration을 막기 위해 barrier layer를 이용하였다 완전 소결된 지지체는 가스투과도와 전기전도도측정을 통하여 특성을 평가하였다.였다.다.m이하의 NH$_3$ 가스를 검출할 수 있었다.기 화강암 관입 이전에 좌수향 전단 운동에 의해 부분적으로 재활성 되었으며, 후기 화강암의 관입 이후에 재차 우수향 전단운동으로 활성화 되었음을 알 수 있다. 이상의 결과를 종합하면 호남전단대는 쥬라기 중기에 발생한 광역적인 우수향의 연성전단운동이나, 운동 특성은 연속적이기 보다는 단속적으로 일어난 것으로 생각된다.리 폐 관류는 정맥주입 방법에 비해 고농도의 cisplatin 투여로 인한 다른 장기에서의 농도 증가 없이 폐 조직에 약 50배 정도의 고농도 cisplatin을 투여할 수 있었으며, 또한 분리 폐 관류 시 cisplatin에 의한 직접적 폐 독성은 발견되지 않았다이 낮았으나 통계학적 의의는 없었다[10.0%(4/40) : 8.2%(20/244), p>0.05]. 결론: 비디오흉강경술에서 재발을 낮추기 위해 수술시 폐야 전체를 관찰하여 존재하는 폐기포를 놓치지 않는 것이 중요하며, 폐기포를 확인하지 못한 경우와 이차성 자연기흉에 대해서는 흉막유착술에 더 세심한 주의가 필요하다는 것을 확인하였다. 비디오흉강경수술은 통증이 적고, 입원기간이 짧고, 사회로의 복귀가 빠르며, 고위험군에 적용할 수 있고, 무엇보다도 미용상의 이점이 크다는 면에서 자연기흉에 대해 유용한 치료방법임에는 틀림이 없으나 개흉술에 비

RF 마그네트론 스퍼터링법을 이용하여 Ar과 $O_2$의 유량을 25sccm씩 흘리면서 $SiO_2$/Si기판 위에 Sn $O_2$ 박막을 증착하였다. 증착된 박막은 columnar 구조로 성장하였으며 많은 입자들이 뭉쳐서 형성된 양배추꽃(cauliflower) 형태의 뭉친 입자(agglomerates)를 가지는 표면형상이 관찰되었다. 분위기에 따른 어닐링 효과를 확인하기 위하여 50$0^{\circ}C$에서 공기와 질소 분위기하에서 열처리하였다. 열처리한 후 표면거칠기가 개선되었으며, 표면형상의 변화가 발생하였다. 특히 50$0^{\circ}C$, 질소분위기에서 어닐링한 경우는 양배추꽃 형태의 표면형상이 소수의 작은 입자가 뭉친 형태로 분리되면서 입도분포가 개선되었다. 이러한 결과는 어닐링 과정에서 발생되는 응력을 완화시키기 위하여 표면형상의 변화가 발생하는 것으로 판단된다. XPS 측정 결과, 질소 분위기에서 어닐링한 후에 OIs와 Sn5/3d 피크가 낮은 결합에너지에 위치하고 있어 산소공공의 농도가 어닐링 전에 비하여 증가하였음을 확인할 수 있다. 어닐링 전후에 Sn $O_2$ 박막의 면저항 측정 값은 XPS 결과와는 달리 질소 분위기 어닐링한 후에 오히려 면저항값이 크게 증가하였다. 이러한 결과는 질소 분위기 어닐링한 후 표면형상의 변화에 기인하여 입자간의 연결성이 저하되어 면저항값이 증가한 것으로 추정된다. 산소분위기에서 어닐링한 후에 전체적으로 전기적 특성의 재현성이 개선되었으며 Sensitivity( $R_{air}$/ $R_{gas}$)가 향상되었음을 확인하였다.하였다.석을 통하여 La의 분포를 확인하였으며, HRTEM 분석을 통하여 미세구조분석을 실시하였다.2463eV였다. 10K에서 광발광 봉우리의 919.8nm (1.3479eV)는 free exciton(Ex), 954.5nm (1.2989eV)는 donor-bound exciton 인 I2(DO,X)와 959.5nm (1.2921eV)는 acceptor-bound exciton 인 I1(AO,X) 이고, 964.6nm(1.2853eV)는 donor-acceptor pair(DAP) 발광, 1341.9nm (0.9239eV)는 self activated(SA)에 기인하는 광발광 봉우리로 고찰되었다.가 높을수록 방출전류가 시간에 따라 급격히 감소하였다. 각 duty비에서 방출전류의 양이 1/2로 감소하는 시점을 에미터의 수명으로 볼 때 duty비 대 에미터 수명관계를 구해 높은 duty비에서 전계방출을 시킴으로써 실제의 구동조건인 낮은 duty비에서의 수명을 단시간에 예측할 수 있었다. 단속적으로 일어난 것으로 생각된다.리 폐 관류는 정맥주입 방법에 비해 고농도의 cisplatin 투여로 인한 다른 장기에서의 농도 증가 없이 폐 조직에 약 50배 정도의 고농도 cisplatin을 투여할 수 있었으며, 또한 분리 폐 관류 시 cisplatin에 의한 직접적 폐 독성은 발견되지 않았다이 낮았으나 통계학적 의의는 없었다[10.0%(4/40) : 8.2%(20/244), p>0.05]. 결론: 비디오흉강경술에서 재발을 낮추기 위해 수술시 폐야 전체를 관찰하여 존재하는 폐기포를 놓치지 않는 것이 중요하며, 폐기포를 확인하지 못한 경우와 이차성 자연기흉에 대해서는 흉막유착술에 더 세심한 주의가 필요하다는 것을 확인하였다. 비디오흉강경수술은 통증이 적고, 입원기간이 짧고,

The oral hygiene of patients admitted to the ICU (Intensive Care Unit) is very important. Critically ill patients are basically immunocompromised ones because of the high risk of infection by various pathogenic bacteria. The mouth is not only the primary site of infection, but also the site of systemic infections. The purpose of this study was to design a mouthpiece type vacuum oral cleaner for the oral care of seriously ill patients. A 3D CAD modeling and flow analysis model were established for a double structure type cleaner and standard tooth model, and their pressure and flow characteristics were analyzed. The pressure inside the oral cleaner was almost constant, but the velocity distribution showed a large difference between the inside and outside of the teeth. The velocity at the center region inside of the teeth was the highest, and the speed decreased as the distance from the center increased. In the analysis of the case where the suction tube was replaced by the drainage tube, the velocity at the center of the outer portion of the teeth was the highest. In order to increase the effectiveness of the oral cleaner, alternating between suction and drainage is proposed, and a design complement to increase the speed of the molar region is required.

Purpose: This study investigated the relationship between the needs for hospice care and quality of life in cancer patients. Methods: Data were collected from 127 cancer patients hospitalized at a university hospital in Chonbuk between October, 2006 to March, 2007. Two instruments were used: cancer patients' need for hospice care, developed by Kang and Kim and quality of life developed by Tae et al. Results: The mean scores were 3.11 out of 4 for hospice care needs, and 5.25 out of 10 for quality of life. The correlation between needs for hospice care and quality of life was moderate and negative (r=-0.395, P<0.01). Among the four groups of needs, physical need was the most strongly correlated with quality of lifer (r=-0.388, P<0.01). The need for hospice care was significantly different according to participants' religion (t=6.02, P<0.05), and duration of disease (F=3.45, P< 0.05). Quality of life was significantly different according to participants' monthly income (F=3.38, P<0.05). cancer stage (F=8.10, P<0.01) and chemotherapy (t=6.09, P=0.015). Conclusion: The results suggested that the cancer patients' hospice care needs should be answered in order to improve their quality of life. While doing so, participants' characteristic need should also be considered.

This study was carried out to determine the factors affecting the trend and usage of Magnetic Resonance Imaging before and after the implementation of National Health Insurance. The research materials were the MRI Execution Data, Health Insurance Review Data, and Medical Expenses in the Health Insurance Data from a General Hospital located in Dae-jeon Metropolitan City from 2004 to 2013. The subjects of analysis were 3,754 people in 2004 (prior to the implementation of Health Insurance), and 4,107-8,603 people from 2005-2013(after the implementation of Health Insurance). In terms of analysis, a comparison of the use of MRI before and after implementation of the Health Insurance of User Characteristics and Provider Characteristics were taken as $X^2$, while factor analysis for the elements that affect MRI usage was carried out by Hierarchical Multiple Regression Analysis. According to the results of this study, the level of use decreased temporarily in the initial application stages of the national health insurance, but it soon increased. In particular, the inspection rates for women, the head and neck, those not subject to the application of the national health insurance, internal medicine, and the inpatients increased. The application of the national health insurance for MRI influenced the increasing inspection rates (P<.0001). As the inspection rate for the MRI increased, it is important to expand the application of the national health insurance to reduce the national health expenditure.
