  • It has been known that XZ CMi is a near-contact binary composed of a hotter and more massive main-sequence primary star close to its Roche-lobe and a Roche-lobe filling giant/subgiant secondary star. There still exist, however, many discordant matters among the previous investigators: diverse mass ratios and temperatures ranging from 0.38 to 0.83 and from 7,000 K to 8,876 K, respectively. In order to make a contribution to the two confusions we conducted spectroscopic and photometric observations. A total of 34 high-resolution spectra were obtained during 4 nights from 2010 and 2018 with the Bohyunsan Optical Echelle Spectrograph (BOES) at the Bohyunsan Optical Astronomy Observatory (BOAO). In parallel, BVRI multi-band photometric observations were carried out 5 nights in 2010 at Sobaeksan Optical Astronomy Observatory (SOAO). In this presentation, we present physical parameters of XZ CMi through the simultaneous analyses of new double-lined radial velocity curves and new light curves. We will also briefly discuss the evolutionary status of the system.

  • 근접촉쌍성 XZ CMi의 BV 측광관측을 수행하여 새로운 광도곡선과 총 7개의 극심시각을 획득하였다. 관측한 극심시각과 지금까지 발표된 극심시각을 수집하여 XZ CMi의 궤도 공전주기를 분석한 결과, 이 쌍성계의 공전주기가 지난 70년간 영년 주기감소와 더불어 규칙적으로 변화함을 확인하였다. 규칙적인 변화를 제3천체에 의한 광시간 효과로 가정하여 0.0056일의 진폭, 약 29년의 주기, 그리고 0.71의 궤도이심율의 광시간 궤도를 결정하였다. 관측된 영년 주기감소($-5.26{\times}10^{-11}d/P$)를 자기제동 항성풍의 각운동량 손실에 의한 주기감소($-8.20{\times}10^{-11}d/P$)와 질량이 작은 반성에서 주성으로 질량 이동에 의한 주기 증가($2.94{\times}10^{-11}d/P$)가 동시에 일어나는 것으로 해석하였다. 이런 관점에서 AML에 의한 주기감소율은 질량 이동에 의한 공전주기 증가율보다 그 크기가 약 3배 정도 크며, 반성에서 년간 $3.21{\times}10^{-8}M_{\odot}$의 질량이 주성으로 이동된다. 관측된 BV 광도곡선을 최근의 Wilson & Devinney 쌍성코드로 주성의 온도를 달리하는 두가지 모형(8200K와 7000K)을 상정하여 분석하였다. 두가지 모형 해 모두 XZ CMi가 반성이 로쉬 로브를 채웠으나, 주성은 아직 로쉬 로브를 채우지 않은 근접촉 쌍성임과 약 15-17%의 제3광도가 이 계에 있음을 보여준다. 그러나, 제3광도를 내는 천체가 주기연구에서 제안한 제3천체와 동일 천체가 아닌 것은 확실하다. 두 모형의 $\sum(O-C)^2$의 차이는 너무 미미하여, 현 시점에서 어느 해가 더 관측치를 잘 맞추는 지를 가릴 수는 없었다. 그간 연구자간에 불일치하였던 질량비의 다양성 문제는 아직도 풀리지 않는 숙제로 남아있다. 이를 해결하기 위해서 분광시선속도곡선과 스펙트럼의 관측과 더불어 정밀 측광관측이 필요하다.

  • This study is about major symptoms of elderly and medical services for elderly in long-tenn care facilities. The subject of this study was 298 patients over 00 years old staying in two geriatric hospitals and two nursing homes. The symptoms and medical services were level of patient classification from RUG(Resource Utilization Group)-III which is applied for both Medicare and Medicaid for skilled nursing facilities reimbursement system in US and designed for measuring patient characteristics and medical staff time. This classification is explained by each patient resource(staff time) utilization level which is called CMI(Case-Mix Index). In this study, the symptoms and services were compared by facility type and they were categorized by level and compared by CMI. Major findings are as follows; 1. There were more elderly who have cognitive function problems in nursing homes than patients in geriatric hospitals. There were more patients with behavioral problems in geriatric hospitals than residents in nursing homes. These results were both statistically significant. 2. The patients in geriatric hospitals received significantly more nursing rehabilitation services, rehabilitation services and extensive services than residents in nursing homes. Other hands, special care services were provided significantly more to residents in nursing homes than elderly in geriatric hospitals. 3. ADL and depression variables had higher CMI when the symptoms were heavier condition. The CMI were not matched with levels of cognitive function problems and behavioral problems. 4. The CMI matched well significantly with levels of nursing rehabilitation services, special care services, and clinically complex services provided for the patient in geriatric hospitals and only nursing rehabilitation services in nursing homes. The CMI for rehabilitation services level and extensive services had regular trends. From the result of this study, the resource utilization level and services provided for elderly in each long-term care facilities were figured out. For the further study, it needs to have more concern about RUG-ill which classification variables were just analyzed.

  • Jules Henri Poincare was great not only as a mathematician brit also as a philosopher of science. He received many honors for his outstanding research. He was elected to the Academie des Sciences in 1887 and was elected President of tile Academy in 1906. In 1908 he was elected to the Academie Francaise and was elected director in the year of his death. The Poincare Conjecture was selected Millennium Prize Problems fly The Clay Mathematics Institute of Cambridge, Massachusetts(CMI). The Board of Directors of CMI have designated a $1 million prize fund for the solution to his problem. In this paper, Poincare's major works, his life, his philosophy and the Poincare Conjecture are given.

  • This study was carried out to evaluate high-school students' nutrient intakes according to the status of depressive trends, and to analyse the in physical and mental health status. The volunteers were 560 high school students selected from 8 provinces, but 511 students were analyzed. A was used for evaluation, The questions were composed in consideration of socio-demographic characteristics, physical health condition by CMI, mental condition assessed by a modified Zung's self-rating depression scale (SDS), and the evaluation of food consumption by a 24 hours recall method. The family situations of the subjects were mostly nuclear family(73%), agricultural work(53%), and having religion(53%). Only 3% of the students suffered depression where as 19% showed depression trendencies. The individual factors that affected their mental condition were family farming and consciousness of academic accomplishment. The health status counted with CMI was 6.2/20 scores. The non-depressed trend group of students had a lower score of CMI than others. The overall nutrient intakes of students were low compared with the Korean RDA for adolescents. The Mean Adequacy Ratio(MAR) of nutrient intakes was only $0.45{\pm}0.23$. Iron, vitamin A, and riboflavin intakes were significantly low and correlated with depressive trend score. The result from the regression analysis showed that CMI, study accomplishment, and vitamin A were the most significant factors influencing mental condition. We concluded that Korean rural high-school students were healthy in mental condition and showed lower rates of depression academic. For there more we could say that the intakes of iron and vitamin A also influenced mental health. Findings confirmed the need of becoming hopeful job of farming and better nutritional status. These situations would be necessary for students to ameliorate the quality of rural living.

  • Korean versions of British Medical Research Council (MRC), Cornell Medical Index(CMI), and American Thoracic Society 78 (ATS-DLD-78) respiratory questionaires were compared with each other, and were tested the stability, in terms of test-retest reliability, of each questions by self-administration of those to 156 medical students. The results obtained and conclusions drawn are as follow: 1. The degree of agreements between responses to the comparable questions of CMI vs MRC, and of CMI vs ATS-DLD-78 were not satisfactory. There were, however, $71{\sim}100$ per cent of agreement between responses to the questions on Cough, Wheezing, Phlegm, Breathlessness, and Chest illness of ATS-DLD-78 vs MRC questionaire. And the ATS-DLD-78 tended to yield greater number of positive responses than MRC (See Table 4). 2. All of the coefficient of stability of each questions in 3 questionaires were statistically significant, ranged $77{\sim}100$ per cent, except that of the question on episode of cough and phlegm in ATS-DLD-78 questionaire (See Table 5-1). The question is composed of two collateral conditions, 'lasting for 3 weeks or more' and 'each year'. 3. It can be insisted that the Section-B questions of CMI is not proper for use in epidemiologic survey on respiratory illness. And rather than MRC, the ATS-DLD-78 questionaire deserves to prefer to be used in epidemiologic studies on respiratory illness. 4. In question-wording, especially, of inquiring past experience, it is possible to lessen the reliability of the question that including collateral conditions such as 'the duration lasted of symptoms', and moreover, of which words are not common usage. For example, for Korean '10days' or 'half a month' is more familiar time unit rather than 'week'.

  • To compare differences of LOS between the group of inpatients via referral centers(the referral group) and the group of inpatients via different routes (the general group) and analyze factors which determine the difference. The 9,484 cases of newly inpatients of Mar., Jun., Sep., Dec. of year 2003 were used for the data. We calculate the Case-mix index of length of stay($CMI_{LOS}$) to compare LOS adjusted with the disease as the ratio of a patient' LOS to all patients' average LOS by 21 classification diagnosis group. We conducted t-test to compare differences of $CMI_{LOS}$ between two groups and multiple regression to analyze factors determining the difference. $CMI_{LOS}$ was 0.94 in the referral group, which was smaller than 1.01 in the general group. LOS was 7.5days in the referral group, which was 0.6day shorter than that in the general group. Multiple regression also showed that $CMI_{LOS}$ was smaller in the referral group than in the general group after controlling patients' general characteristics, diagnostic information variables. The referral centers can be said to playa role in decreasing LOS. We suggest that variety of depth studies on referral centers should be continued at the strategic level of hospital management using additional medical informations.
