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.

스프레이 코팅법으로 제조된 CNT/PVDF 압전 복합막의 자기분극 메커니즘

Carbon nanotubes (CNT) / polyvinylidene fluoride (PVDF) piezoelectric composite films for nanogenerator devices were fabricated by spray coating method. When the CNT/PVDF mixture solution passes through the spray nozzle with small diameter by the compressed nitrogen gas, electric charges are generated in the liquid by a triboelectric effect. Then randomly distributed ${\beta}$ phase PVDF film could be re-oriented by the electric field resulting from the accumulated electrical charges, and might be resulted in extremely one-directionally aligned ${\beta}$ phase PVDF film without additional electric field for poling. X-ray diffraction patterns were used to investigate crystal structure of the CNT/PVDF composite films. It was confirmed that they revealed extremely large portion of the ${\beta}$ phase PVDF crystalline in the film. Therefore we could obtain the poled CNT/PVDF piezoelectric composite films by the spray coating method without additional poling process.

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.

Diameter controlled carbon nanotubes (CNTs) were grown using surface modified iron nano-particle catalysts with aminpropyltriethoxysilane (APS). Iron nano-particles were synthesized by thermal decomposition of iron pentacarbonyl-oleic acid complex. Subsequently, APS modification was done using the iron nano-particles synthesized. Agglomeration of the iron nano-particles during the CNT growth process was effectively prevented by the surface modification of nano-particles with the APS. APS plays as a linker material between Fe nano-particles and $SiO_2$ substrate resulting in blocking the migration of nano-particles. APS also formed siliceous material covering the iron nano-particles that prevented the agglomeration of iron nano-particles at the early stages of the CNT growth. Therefore we could obtain the diameter controlled CNTs by blocking agglomeration of the iron nano-particles.

Resident training programs in South Korea lag far behind that of advanced countries. Given the problems the current system in South Korea has, it is time to consider a new resident training system, resident training for general competencies. Training for the general competencies was practiced in medical fields in advanced countries such as the USA, Canada, and the UK as early as 20 years ago. This system has rendered itself a key component of resident training. Although a few theoretical procedures on general competencies have been practiced in South Korea, the awareness of this concept is still very weak, and the application of the theory to actual training is a long way off from becoming effective. It is urgent for South Korea to adopt competency- and outcome-based training for general competencies. To this end, the knowledge of the concept of this type of training should be improved. Also, the system should be carefully designed to cover a doctor's whole career, and be applied immediately. The competency- and outcome-based training for general competencies is a system that assures high level qualifications. It reflects the needs of our society under the recognition that a professional organization should be committed and accountable in order to respond to social demands. As the benefits of the new training system reach the public and medical care consumers, training-related expenses should be borne by social costs.

공초점 방식을 이용한 기판 사이의 공기갭 측정

이선우,안광신,권남익,Lee, Sun-Woo,Ahn, Kwang-Sin,Kwon, Nam-Ic 한국광학회 2009 한국광학회지 Vol.20 No.4

공초점 방식을 이용하여 두 기판사이의 얇은 공기갭의 두께를 측정하는 방법을 제안하였다. 공기갭이 약 200 nm 이내 일때는 두 기판면이 초점의 레일리 영역 안에 있으므로 완전한 간섭신호를 측정할 수 있었다. 또 초점영역 근처에서의 간섭무늬만 측정되므로 다층 박막중에 존재하는 공기갭이라도 측정할 수 있는 장점이 있다. 간섭무늬 변화가 작은 영역을 제외하면 1 nm 이내의 안정도를 가진다. A confocal technique was demonstrated for measuring the absolute value of an air gap between substrates. Since the two surfaces were in Rayleigh range of the laser focus for air gaps less than 200 nm, complete interference patterns were observed. And since interference patterns were obtained only from the area of focus, it was an advantage of this method that air gaps between multiple thin films could be measured. Stability is less than 1 nm except in the range where the interference pattern changes slowly.

Since the outbreak of COVID-19, there has been a surge in sports conducted through online platforms due to the increase in remote and non-contact activities. Billiards, being suitable for online platforms, has received much attention, leading to research on detecting the position and trajectory of balls. In this paper, we propose a new method utilizing machine vision to detect the position of the balls accurately. The proposed method detects the outline of the ball using the Canny edge detection and then employs simple correlation to determine its position. This correlation-based approach offers satisfactory system performance and is easily applicable in practical systems due to its low implementation complexity and robustness to noise.
