A METHOD FOR DETERMINING MAGNETIC HELICITY OF SOLAR ACTIVE REGIONS FROM SOHO/MDI MAGNETO GRAMS

CHAE JONGCHUL,JEONG HYEWON The Korean Astronomical Society 2005 Journal of The Korean Astronomical Society Vol.38 No.2

Recently a big progress has been made on the measurements of magnetic helicity of solar active regions based on photospheric magnetograms . In this paper, we present the details of Chae's method of determining the rate of helicity transfer using line-of-sight magnetograms such as taken by SORO /MDI. The method is specifically applied to full-disk magnetograms that are routinely taken at 96-minute cadence.

쌍정 경계가 고온 초전도체 Y₁Ba₂Cu₃O단결정의 자기적특성에 미치는 영향

이보화,박정수,김채옥,김의훈,정규채 漢陽大學校 自然科學硏究所 1997 自然科學論文集 Vol.16 No.-

일반적으로 쌍정 경계(twin boundary)는 고온초전도체Y₁Ba₂Cu₃O??? 단결정 내에서 핀 고정점(pinning center)로 작용하여 단결정 시료의 자화에 영향을 미칠 것으로 알려져 왔다. 그러나 이에 대한 체계적인 실험적 연구가 수행되지 않고 있다. 본 실험에서는 Y₁Ba₂Cu₃O??? 단결정 시료를 성장시킨 후, 재 후열처리 과정 중에 단축 가압 방법(uniaxial stress method)을 이용하여 단결정 시료를 detwinning 하였다. 편광효과가 관측된 micro-Raman spectra와 X-ray 회절 패턴으로부터 관측된 (001)면의 주 피크의 2Θ 값을 통해서 단결정이 잘 성장되었음을 확인하였다. 그리고, 반자성 차폐 효과, 마이스너 효과 및 자기이력 측정 결과로부터 detwinning시간이 길어져서 쌍정 경계의 비율이 감소할수록 자화폭이 감소함을 관측하였다. 이로부터 자속 고정(flux pinning)이 줄어듦을 알 수 있었다. 그러므로 쌍정 경계가 고온초전도체 Y₁Ba₂Cu₃O??? 단결정의 핀 고정점으로 작용한다는 것을 알 수 있었다. Generally it is suggested that twin boundaries play the major role of the pinning center in high-Tc superconductor Y₁Ba₂Cu₃???? single crystal and influences the magnetization. However, any systematic experiment related with this expectation has not been performed yet. In this experiment, after growing Y₁Ba₂Cu₃??? single crystals, we detwinned them in oxygen atmosphere using uniaxial stress method while annealing them again. It was verified that single crystals had been grown well from micro-Raman spectra that showed the polarization effect and 2Θ values of (001) plain peaks in X-ray diffraction pattern. We observed that values of magnetization of samples decreased from antimagnetic shield effects, Meissner effect and magnetic hysteresis as detwinning time was increased and this result means that flux pinning decreases. As a result we confirmed that twin boundaries act as a pinning center in high-Tc superconductor Y₁Ba₂Cu₃??? single crystal.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

채정호,전태연,윤수정,최성빈,김대진,김광수 대한생물치료정신의학회 2000 생물치료정신의학 Vol.6 No.1

We report a 70 year-old man with Binswanger's disease associated with mood symptoms. He was apparently well until 15 years ago when the treatment-resistant atypical mood symptoms had been appeared. He showed a fluctuating course in mental disturbance, such as irritable and labile affect, emotional incontinence, and irritable behavior. Two years ago, he was diagnose as hypertension, renal failure, and heart failure. He was admitted to psychiatric ward due to irritable mood, dysarthria, lack of bladder control, gait disturbance, and impulsive behaviors, which had been aggravated during the last 2 months. In physical examination, he had hypertension and both pretibial pitting edema was revealed, and also in neurological examination, exaggeration of deep tendon reflexes and weakness of extremities were found. On mental status examination, he showed irritable and labile mood with mild cognitive disturbances. Brain MRI demonstrated multifocal high signal intensity in periventricular white matter, both basal ganglia, and thalami on the T2 imaging. These findings were compatible with Binswanger's disease with mood symptoms.

In order to study the postures of Korean students, 4,448 students who lives in urban and rural community were participated as subjects and examined by using New York State Posture Rating Test Method with taking photographs. The results were subdivied into postures of body parts, total posture score, leg types, and lateral deviation and analysed as follows. 1. Postures of body parts 1) Head Tilt For elementary and middle school students, the cases of tilted head were shown more frequently in urban than rural and the ratio of the case of the tilted head was increased as grade was higher. On the other hand, high school studends had the opposite tendency. 2) Uneven Shoulder Height For elementary school childs, higher grades had better condition than lower grades, however, for high school students, those in urban had more cases of uneven shoulder than those in rural and girls showed more deviations than boys. 3) Scoliosis Rural childs had more cases of scoliosis than urban childs, but there were no differences of middle and high school students. 4) Uneven Hip Height Urban and rural childs showed some cases of uneven hip which belonged to normal ranges. Middle and high school studedns werw nearly perfect in the hip height, therefore the condition seems to change as they grow older. 5) Pronated Ankles For this part, those in rural showed better conditions than those in ruban in all age groups and, especially high school third grade students were more satisfactory in rural than urban(84% vs 50%) 6) Forward Head Elementary and middle school students appeared to be satisfactory regardless of age, sex and district, however 32% of high school girl students had forward head. 7) Round Shoulders Many students had round shoulders and some of them revealed severe conditions, There were large differences between urban and rural students. 8) Trunk Hyperextension Generally, girls showed better conditions than boys in trunk posture and, for high school boy students, conditions were differed according to their grades. 9) Sagging Abdomen More cases of sagging abdomen were revealed in ruban that rural for elementary girl students(30% vs 14%). For middle and high school students, there were differences between sex, boys showing more cases than girls in middle school and girls in high school. 10) Lordosis There were differences between urban and rural for elementary childs and high school boy students, however no differences were detected in other groups. Mean degrees of lordosis had a tendency of increasing as the age grew. 2. Total Posture Score For elementary childs, both boys and girls showed differences between urban and rural(75.95 vs 70.73, 75.16 vs 82.42), and, in rural girls seems to be more satisfactory than boys in comparison between boys and girls(p<. 001). In middle school group, rural students appeared to be significantly(p<.05) better than urban students for both sex(83.88 vs 81.93, 75.93 vs 75.02) and the result was same for the high school group(86.52 vs 84.03, 80.07 vs 78.10) 3. Leg types For elementary childs, girls revealed more cases of bowlegs and knock-knee than boys(6% vs 8.2%, 20.5% vs 30.3%). In high school group, the girls in rural showed more cases of bowlegs than those in urban(29.7% vs 13.0%) and, the knokc-knee, the result was opposite(19.3% vs 28.4%). 4. Lateral deviation 1) Head Tilt In elementary group, 11% of boys and 6.3% of girls had lateral deviation and, for high school students, 3.6% of boys and 5.4% of girls showed the deviations revealing girls had more cases of deviation than boys. 2) Uneven Shoulder Height 1.8% of elementary boys and 0.5% of girls had uneven shoulder and totally 1.5% of high school students showed uneven shoulder height. 3) Scoliosis 15.5% and 17.4% of elementary boys and 21.6% and 20.7% of girls deviated to right and left respectively. Urban students showed general trends to leftward deviation while rural students showed rightward deviation. 4) Uneven Hip Height In this part of posture, they showed good conditions in all age, sex, and district.
