The turning circle of a ship is the path followed by her center of gravity in making a turn of 360° degree or more with helm at constant angle. But generally it means her path traced at full angle of the rudder. For the ordinary ship the bow will be inside and the stern outside this circle. It has been usually understood that the turning circle is not essentially affected by ship's speed at Froude numbers less than about 0.3. However, it is recently reported that the speed provide considerable effects upon the turning circle on piloting many ships actually at sea. In this paper, the author analyzed what effects the speed could provide on the turning circle theoretically from the viewpoint of ship motions and examined how the alteration of the speed at Froude no. under 0.30 affect the turning circle actually, through experiments of actual ships of a small and large size.

Oh, Myueng Guen,Kim, Jin Hwa,Han, Mi Ah,Park, Jong,Ryu, So Yeon,Choi, Seong Woo Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.8

Background: Previous studies have generated conflicting evidence regarding associations between family history and survival after gastric cancer surgery. In this study, we investigated this question using a meta-analysis. Materials and Methods: To identify relevant studies, PubMed and Embase databases were searched up to June 2013. Two reviewers independently assessed search results and data extraction of included studies. Hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival (OS) were calculated based on fixed- or random-effects models. Homogeneity of effects across studies was assessed using $x^2$ test statistics and quantified by $I^2$. Results: A total of five studies were selected according to the inclusion criteria. The total number of patients included was 2,030, which ranged from 145 to 598 per study. There was no significant difference in OS by family history of cancer (HR=0.83, 95%CIs=0.50-1.38), but subgroup analysis of patients with a first-degree family history of cancer (HR=0.74, 95%CIs=0.60-0.93) and gastric cancer family history (HR=0.56, 95%CIs=0.41-0.76) tended to show better OS in these patients. Conclusions: This meta-analysis suggests that a first-degree family history of cancer or gastric cancer family history is associated with better survival of gastric cancer patients after surgery, after a systematic review of five previous studies. These results can be applied by clinicians when counselling patients regarding their risk of death from gastric cancer. Further study is needed to investigate the underlying mechanism between family history and survival in gastric cancer patients.

Guen Hyung Oh,TaeWan Kim 한국진공학회 2021 한국진공학회 학술발표회초록집 Vol.2021 No.2

Herein, we demonstrate the n-type conductivity suppressing property of the tellurium (Te)-doped multilayer MoS₂, grown by metal-organic chemical vapor deposition. The back-gated as-grown Te-doped multilayer MoS₂ field-effect transistor (FET) is observed to exhibit p-type behavior. Enhanced device performance has been achieved by doping the p-type MoS₂ transistors in high-K dielectric gate insulators with Te. pFET devices containing Al₂O₃ dielectric insulators exhibit extremely high performance, including a maximum mobility of ~182 cm²/V·s, a low subthreshold swing of ~215 m V/dec.

Assessing Activity Limitation Among Cancer Survivors in Korea Using Data from a Nationwide Survey

Oh, Myueng Guen,Han, Mi Ah,Byeon, Yu Mi,Bae, Kyung Min,Choi, Seong-Hyung Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.7

Background: More than 1 million cancer survivors reside in Korea. We here investigated activity limitations of cancer survivors compared to controls without a history of cancer. Materials and Methods: Using the 4th and 5th Korea National Health and Nutrition Examination Survey (2007-2012) data, we identified 1,155 adult cancer survivors. Activity limitations were defined as limitation in activities of daily living, experience of lying in a sickbed, and number of days lying in a sickbed during the last month. Descriptive analysis and multiple logistic regression compared these measures for survivors and controls by sex and age groups. Results: Approximately 29.4% of cancer survivors reported limitation in activities of daily living, 14.6% experienced lying in a sickbed, and 4.3% experienced more than 15 days lying in a sickbed during the last month. After controlling for demographic and health-related factors, cancer survivors were more likely to report activity limitation than controls. The associations were similar across sex and age groups. Conclusions: Cancer survivors have increased activity limitation compared to controls and these limitations persist across sex and age. Targeted interventions and improved management are essential for improving cancer survivor daily life.

Comparison of Ionic Liquid and Ion-Gel Top-Gate MoS₂ Field-Effect Transistors

Guen Hyung Oh,TaeWan Kim 한국진공학회(ASCT) 2021 Applied Science and Convergence Technology Vol.30 No.5

Polymer electrolytes and ionic liquids (ILs) have attracted significant interest in applications as gate dielectrics. In this study, we fabricated top-gated molybdenum disulfide (MoS₂) thin-film transistors using IL and ion-gel (IG) gate dielectrics. Room-temperature Raman spectra measurements indicated a dominant peak spectral emission at 358 cm<SUP>−1</SUP> (<SUP>1</SUP> 2) and 406.44 cm<SUP>−1</SUP> (1g) associated with bilayer MoS₂ films. The fabricated thin-film field-effect transistors (FET) with IG gate dielectric exhibited band transport with a highest mobility of 0.5 cm²/V⋅s, and a poor ON/OFF ratio of ~10. By contrast, the FET with IL gate dielectric exhibited a 3400 % improvement in terms of the mobility (17.9 cm²/V⋅s), and a 1000 % improvement of the ON/OFF ratio (~100).

공유메모리 다중프로세서 시스템에서 자원을 공유하기 위한 시분할, 공간분할 그리고 gang 스케줄링과 같은 기존의 기법들은 시스템의 활용도를 개선하기 위하여 각 프로세서들의 병렬성에 대한 성능은 희생되었다. 본 논문에서는 LLPC라는 프로세서 할당 기법을 제안하였다. 이 기법은 시스템과 과부하 없이 각 application의 병렬성을 극대화함으로서 기존의 시분할과 gang 스케줄링을 개선할 수 있었다.

정신장애인 복지의 패러다임 전환으로서 ‘당사자주의’ : 새로운 패러다임으로서 함의와 사상적 체계화의 방향 설정을 중심으로

오세근(Oh, Se-guen),이명호(Lee, Myoung Ho) 동양사회사상학회 2022 사회사상과 문화 Vol.25 No.1

우리나라 정신장애인이 경험하는 사회생활의 어려움에 대한 국제기구의 문제 제기, 국내 학계와 정신장애인 운동단체의 정책 제안에 대한 종합적인 법제도적 응답이 2017년 ‘정신건강복지법’이다. 그렇지만 현실은‘정신건강복지법’ 시행 이후에도 정신장애인 복지의 틀은 격리와 입원 치료라는 이전 방식에서 크게 벗어나 있지 않다. 정신장애인을 격리해서치료하는 방식의 실효성에 대한 의문과 인권 침해에 대한 사회적 반성은 정신장애인 복지의 새로운 체계 구상과 실천을 요구한다. 이 글은 정신장애인 복지 패러다임 전환의 가능성과 그 근거를 베델의 집의 ‘당사자주의’라는 현실적 모델을 통해 살피는 것이다. 먼저 패러다임으로서 ‘당사자주의’가 제기하는 새로운 메시지와 그 의미를 명확히가늠하기 위해 기왕의 주류적 정신장애인 복지 패러다임인 ‘생의학 모델’ 과 ‘사회 모델’의 주요 내용과 패러다임의 변화 과정을 개관한다. 이어서, 새로운 패러다임으로서 당사자주의의 이론적, 실천적 함의와 내용을 검토한다. 다음으로 당사자주의가 정신장애인복지 실천의 새로운 패러다임으로서 자리매김하는 데 긴요한 사상적 체계화의 방향을 생각해 본다. 당사자주의 패러다임은 정신장애인에 대한 생의학 모델의 격리 입원치료 방식이나 사회 모델의 정책, 제도, 서비스 체제로서 탈시설화와 지역사회 보호를 넘어선 지점에 있다. 정신장애인이 사회복지 서비스의 대상으로부터 일상생활을 향유하는 시민으로서 지역사회 경제활동에 참여하면서 사람과 연결되고, 사회적 역할을 통해 자신의 말을 세상에 능동적으로 발신하면서 자신의 고통을 들여다보고, 자신이 들여다보지 못한내밀한 정신의 심연을 친밀한 사람과 함께 어루만져 가면서 정상화와사회통합을 체현한 것이다. 이런 점에서 정신장애인 복지의 새로운 패러다임으로서 당사자주의는 정신장애인 당사자의 생활 가운데서 생성된실천 모델이며, 당사자 활동 경험의 지속과 축적에서 생겨난 자조(정신장애인 스스로 돕고 격려함)와 자치(정신장애인 스스로가 결정하고 돌보며 치료함) 활동에서 산출된 지식과 생활양식 그 자체를 가리킨다. The Mental Health Welfare Act 2017 was a comprehensive institutional response to the international organization’s problem-posing regarding the difficulties in social life experienced by the mentally disabled and policy proposals by domestic academia and activists. However, the reality is that even after the enforcement of the Mental Health Welfare Act, the framework of welfare for the mentally disabled is not far from the previous method of isolation and hospitalization treatment. It requires that the new concept and practice of welfare for the mentally disabled be based on doubts about the effectiveness of isolation and treatment for the mentally disabled and social reflection on human rights violations. This article examines the basis and possibility of a shift in the paradigm of mental health services for mental disorders through Bethel House’s self-directed research model. First, to clearly present the new message and its meaning raised by ‘self-directed research model’ as a paradigm, it will be introduced to the paradigm change process of the mainstream welfare paradigms for the mentally disabled, ‘biomedical model’ and ‘social model’. Then, the self-directed research model’s theoretical and practical implications and contents are reviewed as a new paradigm. Finally, we consider the direction of ideological systematization, which is essential for the self-directed research model to establish itself as a new paradigm in the practice of mental health services for mental disorders. The paradigm is beyond deinstitutionalization and community care. As citizens who enjoy daily life, mentally disabled people are connected to people while participating in economic activities in the community, actively communicating with others through their social roles and looking into their pain. It embodies normalization and social integration by touching the inner spirit’s pains that have not been explored with close people. In this regard, as a new paradigm for mental health services for mental disorders, the self-directed research model is a practical model created in the lives of the mentally disabled. Also, it refers to the knowledge and lifestyle itself, which are produced from self-help (helping and encouraging themselves) and autonomy (making their own decisions and treating themselves) activities.
