Objectives The objective of this study was to investigate the differences in sociodemographic and clinical characteristics, temperaments, and quality of life between panic disorder (PD) patients with and without major depressive disorder (PD+MDD and PD-MDD patients, respectively). Methods We compared 411 PD-MDD and 219 PD+MDD patients. All patients who were drug-free for at least 1 month were assessed at initial outpatient visits before the administration of medication. The following instruments were used for assessment: the NEO Personality Inventory-Neuroticism (NEO-N) ; the Temperament and Character Inventory-Harm Avoidance (TCI-HA) ; the State-Trait Anxiety Inventory (STAI) ; the Intolerance of Uncertainty Scale-Short (IUS); the Anxiety Sensitivity Index-Revised (ASI-R); the Beck Depression Inventory (BDI) ; the Beck Anxiety Inventory (BAI); the Penn State Worry Questionnaire (PSWQ) ; the Generalized Anxiety Disorder for 7 item (GAD-7) ; the Albany Panic and Phobia Questionnaire (APPQ) ; the Panic Disorder Severity Scale (PDSS) ; the Early Trauma Inventory Self Report-Short Form (ETISR-SF) ; the Scale for Suicidal Ideation (SSI) ; the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) ; the Sheehan Disability Scale (SDS) ; and the Short Form health survey (SF-36). Results Compared to the PD-MDD patients, the PD+MDD patients were younger and more likely to be unmarried. They showed higher rates of unemployment, lower levels of education and income, younger age of onset, more previous suicide attempts, a greater incidence of agoraphobia, and more previous treatments. The PD+MDD patients showed significantly higher scores on the NEO-N, the TCI-HA, the STAI, the IUS, the ASI-R, the BDI, the BAI, the PSWQ, the GAD-7, the APPQ, the PDSS, the ETISR-SF, and the SSI. In addition, the PD+MDD patients showed significantly lower quality of life than did the PD-MDD patients. In contrast with previous studies, we observed no significant differences between the two groups in terms of gender, duration until treatment, and psychiatric comorbidities. Conclusions This study showed that the PD+MDD patients have more early trauma experiences, higher levels of anxiety-related temperaments, more severe panic and depressive symptoms, and lower quality of life than the PD-MDD patients.

In 1995, the costumes were restored in an unknown woman's tomb at the Jeonju Lee's family cemetery in Gapyeong, Gyeonggi-Do, and there are currently nine items remaining. In this study, we first introduced these 9 relics to academia and analyzed the morphological characteristics of the costumes. We also estimated the time and person of burial compared with costumes unearthed from other burials. Jeogories (short jacket) are all four items. One of these items was unusual in shape, and the upper part of the seop (gusset) was wrinkled and shaped. This type of Jeogori appears only till the 1520s in other tombs. There are also two skirts, one of which is characterized by a superimposed pattern. The top and bottom / middle part of the skirt were rolled up, and the skirt, which was double-rolled up in this way, was first discovered. An analysis of the shape of Jeogori and skirt indicated that the person buried in the Jeonju Lee's family tomb was believed to have survived until the early 16th century. Based on these estimated periods, as a result of looking at the genealogy of Jeonju Lee's family, it was concluded that the tomb was probably a woman named Lee Geum Myeong (李金命) born in the mid-15C and died between the late 15C and the early 16C.

In this paper, we discuss the fabrication of metal alloy resistors. We connected them in parallel to estimate their resistance and temperature coefficient of resistance (TCR). The fabricated resistors have different resistances, 5 and $10{\Omega}$ and different TCRs, 50 and $200ppm/^{\circ}C$. Each resistor was confirmed to have the correct atomic composition through the use of energy dispersive X-ray (EDX). The resistors' electrical properties were confirmed by measuring resistance and TCR. The resistance and TCR of the resistors connected in parallel were estimated through the increase in resistance due to the increase in temperature, and were compared with the measured values. We are confident that this TCR estimation technique, which uses the increase in resistance due to temperature, will be very useful in designing and fabricating resistors with low and stable TCR.

이선우,장우권,Lee, Sun Woo,Chang, Woo Kwon 한국정보관리학회 2021 정보관리학회지 Vol.38 No.3

이 연구에서는 COVID-19 발병 전후 대학도서관 홈페이지 실제 이용 데이터를 조사하여 이용자들의 이용행태를 분석하고, 바이러스 발병 이전과 이후의 데이터를 대조하여, 팬데믹 상황에서 대학도서관이 보다 효율적인 정보서비스를 할 수 있도록 개선방안을 제안하고자 한다. 이 연구는 C대학교 홈페이지에서 이루어진 이용자 트래픽을 '구글애널리틱스를 활용하여', COVID-19 바이러스가 발병하기 이전인 2018년 1월부터 2018년 12월까지와 바이러스 발병 이후인 2020년 1월부터 2020년 12월까지를 비교분석하였다. 웹 트래픽 변수는 세션, 사용자, 페이지뷰 수, 세션당 페이지 수, 평균 세션 시간, 이탈률을 측정지표를 기준으로 '이용자 정보', '경로', '사이트 행동' 3가지 특성으로 구분하여 분석하였다. 연구결과를 요약하면, 첫째, COVID-19 발병 이전 1월 1일부터 1월 20일까지의 데이터와 대조했을 때, 2018년 이후 사용자, 신규방문자, 세션 모두 3년 동안 감소하였지만, 2020년은 2019년 대비 사용자, 신규 방문자, 세션 모두 증가하였으며, 2020년 바이러스 발병 이전 상승세를 보였던 사용자당 세션 수, 페이지뷰 수, 세션당 페이지 수가 크게 증가하였다. 둘째, 사회적 거리 두기 2단계로 격상함에 따라 대학도서관 홈페이지 이용 추이에도 변화가 나타났다. 재학생이 가장 적었던 2020년, 2018년 대비 2020년에 페이지뷰가 10만 뷰 더 증가했으며, 세션당 페이지 수 역시 2018년 대비 약 2페이지를 더 조회한 10.46을 기록했다. 이탈률 역시 2018년, 2019년 14.38을 기록한데 반해, 2020년 1% 포인트 가량 감소한 13.05를 기록하여 사회적 거리 두기 단계가 격상한 시점에, 더욱 활발한 홈페이지 이용이 이루어졌다. In this study, by examining the actual usage data of the university library website before and after COVID-19 outbreak, the usage behavior of users was analyzed, and the data before and after the virus outbreak was compared, so that university libraries can provide more efficient information services in a pandemic situation. We would like to suggest ways to improve it. In this study, the user traffic made on the website of University C was 'using Google Analytics', from January 2018 to December 2018 before the oneself of the COVID-19 virus and from January 2020 to 2020 after the outbreak of the virus. A comparative analysis was conducted until December. Web traffic variables were analyzed by classifying them into three characteristics: 'User information', 'Path', and 'Site behavior' based on metrics such as session, user, number of pageviews, number of pages per session time, and bounce rate. To summarize the study results, first, when compared with data from January 1 to January 20 before the oneself of COVID-19, users, new visitors, and sessions all increased compared to the previous year, and the number of sessions per user, number of pageviews, and number of pages per session, which showed an upward trend before the virus outbreak in 2020, increased significantly. Second, as social distancing was upgraded to the second stage, there was also a change in the use of university library websites. In 2020 and 2018, when the number os students was the lowest, the number of page views increased by 100,000 more in 2020 compared to 2018, and the number of pages per session also recorded10.46, which was about 2 more pages compared to 2018. The bounce rate also recorded 14.38 in 2018 and 2019, but decreased by 1 percentage point to 13.05 in 2020, which led to more active use of the website at a time when social distancing was raised.

In this paper, we investigated the relations between dispersion of CNTs (carbon nanotubes) and electrical conductivity in the CNT/PVDF (polyvinylidene fluoride) composite film. By adding hydrophobic CNTs as filler into the PVDF matrix, we fabricated hydrophobic and electrically conducting polymer coating film. Dispersion of CNTs in the CNT/PVDF composite film plays a significant role in terms of electrical conductivity and wetting property. Spray coating method was used to form the CNT/PVDF composite films by injecting the dispersed CNTs in the PVDF solution with different weight ratios from 0.7 wt% to 7 wt%. We investigated the electrical properties and contact angles of the CNT/PVDF composite films with the CNT concentration. Finally we discussed the conducting mechanism and feasibility of the CNT/PVDF composite film for the conducting polymer films.

Objectives : This study was executed in order to evaluate the effects of electroacupuncture on upper-extremity spasticity control in stroke patients. Methods : Eighteen patients with stroke were enrolled and classified into two groups, the study and control group. The control group did not receive any oriental medical treatment. In the study group, the electroacupuncture points were applied to Kokt'aek (PC3) and $Ch'{\u{o}}ch'{\u{o}}n$ (PC2), Naegwan (PC6) and $Ch'{\u{o}}kt'aek$(LU5) of the affected limb. H-reflexl M-response ratio (HIM ratio), modified Ashworth scale (MAS) and Fugl-Meyer motor function assessment (FMA) were used for evaluation of spasticity control before electroacupuncture, within two hours after electroacupuncture, and at two weeks. Results : In MAS, the study group declined more than the control group. but there was no statisticallysignificant consideration. In H/M ratio. the study group was more efficient than the control group. and spasticity decreased successively during the series in the study group. In FMA, motor function in the study group improved more than in the control group and motor function in the study group increased successively during the series. Conclusions : These results showed that electro acupuncture was a useful method to decrease upper-extremity spasticity in patients with stroke. Further studies are needed to explore more cases and the long-lasting carryover effects on upper-extremity spasticity in electroacupuncture.
