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.

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.

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.

COVID-19 전후 대학도서관 홈페이지 이용행태에 관한 연구: C대학교 도서관을 중심으로

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.

외국 전공의 수련교육의 제도 및 시사점

이선우,Lee, Sun Woo 연세대학교 의과대학 2018 의학교육논단 Vol.20 No.3

Medical education, competency, and outcome-based medical education started as part of the basic medical education curriculum in advanced countries 20 years ago, and such an approach was adopted in residency training. General competency training is at the core of residency training in advanced countries, and it goes beyond competency and outcome-based training to the extent that in a milestone training system, competency development is expected and measured with set competency achievements at each level. Recently, for the purpose of ensuring that doctors uphold patient safety and fulfill their obligations, entrustable professional activities (EPA) were applied at the beginning of residency when doctors move away from clinical trials and start actual care. The adoption of EPA in all residency training curriculum has spread very rapidly in the United States, United Kingdom, and Canada. Presently, Korea lags behind other countries significantly as the adoption of competency and outcome-based medical education in residency training has just begun. It is time to identify the current state of the Korean residency training system, and then design and practice a well-established system with a long-term view based on cooperation across the whole medical industry.

전공의 공통역량의 개념과 개발

이선우,Lee, Sun Woo 연세대학교 의과대학 2017 의학교육논단 Vol.19 No.2

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.

의과대학생의 졸업 후 전공선택을 위한 진로지도

이선우,Sun Woo Lee 연세대학교 의과대학 2024 의학교육논단 Vol.26 No.1

The author recommends the creation of a nationwide career guidance program at the national level through the establishment of a long-term cohort, involving collaboration among medical schools nationwide. This cohort would be constructed for the purpose of analyzing correlations from admission to medical school to post-graduate education, facilitating the development of a career guidance program. This will aid in career development through students' self-analysis and competency building. Each medical school should operate a systematic career guidance program. Career guidance for post-graduate major selection should be included in the regular curriculum. Schools are advised to operate student counseling rooms for various career guidance services. For example, medical schools can operate 1:1 career counseling, academic counseling, career guidance surveys, psychological tests, and counseling. It is advisable to establish a mentor-professor system, connect mentor professors, and build a network of experts related to majors to provide immediate support according to students' needs. Professional mentor training should be provided to mentor professors. To provide opportunities for students to experience their career paths in advance, early clinical exposure, long-term integrated clinical practice, community-based clinical practice, participation in student research programs, career fairs, and student internship programs are recommended. In South Korea, it is necessary to systematically operate the internship system and make improvements to facilitate optical career choices. Additionally, considering the significant influence of social factors on students' career choices in South Korea, efforts should be made to identify and address the issues related to these social factors.

하절기 단열 성능 향상을 위한 통기성 지붕의 통기 구조에 관한 실험적 연구

박상훈(Park, Sang-Hoon),조구상(Jo, Goo-Sang),이선우(Lee, Sun-Woo),여명석(Yeo, Myoung-Souk),김광우(Kim, Kwang-Woo) 대한건축학회 2014 대한건축학회논문집 Vol.30 No.9

The thermal performance of the building envelope is mainly required for guaranteeing a comfortable and hygienic interior climate. A roof is a part of the building envelope which provides protection from the thermal damage of the sun. To improve this protection ability, we can consider using a ventilated roof, which has a ventilation layer known as a cavity, beneath the roof cover panel. The objective of this study is to evaluate the influence of such factors as the slope of the roof, size or shape of the openings (i.e. inlet or outlet), effective cross section and cavity depth on the improvement of the air flow in the cavity for better thermal performance of the ventilated roof. In this study, the influence on air flow which is caused by the characteristics of these elements is researched. The evaluations are carried out by way of experiments.

민주주의 공고화에 있어 ‘법의 지배’의 우선성

이선우(Lee, Sun-Woo) 한국정치학회 2017 한국정치학회보 Vol.51 No.1

본 논문은, 탈공산 러시아 사례를 통해, 신생민주주의 국가에서의 민주주의 공고화의 실패와 권위주의로의 퇴행을 ‘법의 지배’ 원리의 취약성과 연계시켜 설명하고자 한다. 특히 이를 위해 옐친 대통령 시기의 민주화 양상 및 그 공고화의 잠재성을 먼저 평가하고, 뒤이어 푸틴 집권 이후 정치체제가 다시금 준권위주의의 형태로 퇴행하게 된 주요 원인을 ‘법의 지배’ 원칙의 부재로부터 도출하려 한다. 탈공산 러시아의 경우, 선거민주주의가 정착된 이후로 정치적 권리와 시민적 자유가 공히 발전경로에 진입했던 사례로 평가된다. 하지만 푸틴 집권 2기 출범 이후 러시아의 민주주의가 계속 발전도상에 위치해있다고 평가하는 것은 더 이상 가능하지 않은 일일 것이다. 즉 절차적 민주주의의 구축 이후 ‘법의 지배’의 원칙이 빠른 시간 안에 확립되지 못하자 정당체계 및 시민사회의 내적 불균형이 재생산되었으며, 이는 곧 정치적 경쟁을 약화시킴으로써 정례적 선거조차 무의미하게 만들어버렸다. 결국 신생민주주의 국가가 민주주의의 공고화를 달성할 수 있는가 여부는 우선적으로 ‘법의 지배’ 원칙이 얼마나 빨리 확립될 수 있는가에 달려 있는 것이다. This article explains the failure of democratic consolidation of a country in democratic transition and its step back to authoritarianism, focusing on the weakness of the “rule of law” principles, through a case study of post-Soviet Russia. For this purpose, this paper initially assesses the appearance of democratization and potential of democratic consolidation in the Yeltsin period, and furthermore deducts the main cause of Russia’s step back to semi-authoritarian political system in the Putin presidency from the absence of “rule of law”. In post-Soviet Russia, both political rights and civil liberty were assessed as being in progress. However, it seems no longer possible to say that Russian democracy has been developing after the beginning of Putin’s second term. That is, as the principles of “rule of law” could not be initially settled, imbalances within the political system and civil society were reproduced, which shortly made even regular elections themselves meaningless, by undermining the extent of political competitiveness. Therefore, whether an emerging democracy could achieve democratic consolidation or not can be said to depend upon how soon the “rule of law” principles would be initially settled.

공무원 복지부동형태의 원인과 치유방안 모색 - 인사관리를 중심으로 -

이선우 ( Sun Woo Lee ) 한국행정학회 1997 韓國行政學報 Vol.31 No.3

이 논문은 행정개혁에 부정적인 감정을 가진 공무원들이 복지부동의 행태를 나타낼 수 밖에 없는 원인을 분석하고 그들의 행태를 치유하고 행정개혁에 열정을 가지고 참여할 수 있도록 하는 방법을 찾기 위해 인력관리면에서 접근하고 있다. Maslow의 다섯가지 욕구인 생리적 욕구, 안전에 대한 욕구, 사회적 욕구, 존경의 욕구 그리고 자아실현의 욕구가 충족되어지면 공무원들의 복지부동 행태는 상당히 사라질 것이라는 결론에 도달한다. 다음으로 각각의 욕구들을 충족시켜 공무원들이 행정개혁에 긍정적 감정을 갖도록 하기 위해서는 인사관리 방법상에 공정성과 전환성 및 챔피언십 등의 세가지 중요한 변화가 있어야 함을 강조한다. 공정성이란 업무성과 측정과 공무원 개개인들에 대한 대우와 기회부여 및 보수와 혜택 등의 인사제도의 운용에 있어서 공정성이 확보되어야 함을 의미한다. 전환성은 업무수행과정, 공무원들의 사고와 행위 그리고 직원관리 방법상에 있어서의 대전환을 포함한다. 마지막으로 공무원들이 업무수행과정에서 자신의 일에 도전의식과 성취감을 가지고 챔피언십을 느낄 수 있도록 인사제도가 변한다면 공무원들이 보다 긍정적 감정을 가지고 개혁에 동참할 수 있을 것이라는 것이 이 연구의 요지이다.
