        중년여성의 요통에 따른 골밀도 측정

        강점덕,김종봉 대한정형물리치료학회 2001 대한정형도수물리치료학회지 Vol.7 No.1

        Objectives: The objective of this study was to investigate analysis of bone mineral density according to Women with low back pain women. Methods: The data were collected from women who visited Physical Examination Center of a Catholic University hospital located in Daegu. Questionnaires were completed by 50 women during the period from July 20, 2000 to January 12, 2001. The sample was divided into three groups(the normal group of 16 cases and the osteopenia group of 12cases and the osteoporosis group of 22 cases). Bone mineral density(BMD) of lumbar spine was measured using energy absorptiometry. Results: The bone mineral density of the lumbar spine decreased with aging. The bone mineral density of the lumbar spine decreased with the serum Calcium and Phosphorus and Alkaline phosphatase increased. The mean bone mineral density of the lumbar spine of healthy women in age(50∼59) was 0.87g/㎠, the lumbar spine of women with low back pain in age(50∼59) was 0.77g/㎠. In the multiple regression of risk factors to bone mineral density(BMD) oflumbar spine were correlated with age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores(p<0.05). The experience for LBP increased as weight increased(Odds ratio=999.000). The experience for LBP increased as number of Exercise decreased(Odds ratio=999.000). The experience for LBP increased as menopause existence increased(Odds ratio=999.000). The experience for LBP increased as serum Calcium and Phosphorus increased(Odds ratio=999.000). however all four variables had significant no relationship. The correlation in variables in relation to low back pain and bone mineral density, age showed contra-correlation with low back pain existence. Alkaline phosphatase(p<0.01). Weight showed contra-correlation with body mass index(BMI)(p<0.01). Exercise time showed correlation with number of exercise(p<0.01). The loving food of taste showed contra-correlation with Alkaline phosphatase(p<0.05). Bone mineral density showed correlation with menopause existence(p<0.05). Conclusion: Results from this study indicated that a statistically significant association between bone mineral density of the lumbar spin and age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores. In logistic regression test, there were no related variables. The combination of bone mineral density measurement and assessment of the bone turnover rate by measuring biochemical would be helpful for the treatment of patients with risks of osteoporosis. The more precise study for risk factors to osteoporosis is essential.

        16세기 경상도 방언의 모음체계 연구

        박종덕 한말연구학회 2003 한말연구 Vol.- No.12

        In this study, it was intened to infer the vowel system in Gyeongsang-do dialect of the 16th century from /?/,/ㅔ/,/ㅐ/,/-/,/ㅓ/,/ㅟ/,/ㅚ/ whixh are thought to have caused them. In conclusion, it has been found out as follows. First,/?/ functioned as a phoneme both in the first syllable and the non-first syllable. Second,/?/>/l/ was a voluntary alternation of phonems. Third, /ㅔ/,/ㅐ/,ㅟ/,/ㅚ/ were practically realized into /aj/, /αj/,/uj/,/oj/. Fourth, there were indications that /ㅔ/,/ㅐ/ were realized into /e/,/ε/. Fifth, /ㅡ/,/ㅓ/ were clearly distinct both in the first syllable and the non-first syllable. On the basis of the above, the vowel system in Gyeongsang-do dialect of the 16th century could be concluded as follows. <table 1> The Vowel System in the 16th century's Gyeongsang-do Dialect( *means that there is a possiblity of having been realized.)

        This study is to construct the scientific system of reaction time based on the research results until now, and present new research direction. The study of reaction time since then performed by Cattail's experiment on 1880 for estimation of human power has been an important independent variable in analysis of information processing together with appearance of the cognition psychology(Maisto & Baumeister, 1984), and Donders(1969) who tried to test the stages of processing in human behavior firstly. He assumed that the information processing was performed in serially, and planed experimental design that constituted simple RT, choice RT, discrimination RT. These design has been used to understand human movement action to date. Reaction time is influenced by personal factors (gender, age, physiological condition, amount of practice) and environmental factors ( stimulus intensity, stimulus-response compatibility, number of stimulus alternatives, response complexity). One variation of the RT method is EMG trace taken from a muscle involved in the movement. This paper introduce TeleScanⅡ-EMG measurement device(LAXTHA Inc, 2001), which analyze RT into premotor RT and motor RT. RT is continuously studied not only the academic basic of motor control but also clinical data in human movement.

        동일한 시료에 대한 국내 기관간의 STR 분석결과 비교 : STR 유전자좌 분석법의 표준화 설정을 위하여

        박종태,신경진,양윤석,우광만,이숭덕,이승환,이정빈,정연보,조승희,한길로,한면수,홍승범 大韓法醫學會 2001 대한법의학회지 Vol.25 No.1

        This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

      • 국사학습 연표자료의 실태와 개발방안

        김덕진,박태선,정종재 전남사학회 2002 역사학연구 Vol.19 No.-

        A chronological table of Korean history is a study material which is arranged for us to understand the course of a historical development and a table that historical events are arranged and systematized in a chronological order as time passes, As a middle school Korean historical textbook has 10 chronological tables and a highschool Korean historical textbook has 6 chronological tables, they are very useful to take a general view of the unit. But the years which can represent the unit are left out or the facts which are not referred to in the main text are wrote down. On the other hand, the facts which are written down in a chronological table are not seen in the main text or in the general chronological table. In addition, a middle school historical textbook has two main chronological tables while a highschool historical textbook has nothing. Therefore we should write down the historical facts as 3 aspects of the followings. First, There can be a periodical history divided into a short period, a middle period, and a long period. Second, There can be a classified history divided into a political, an economical, a social, and a cultural affairs. A third, There can be a thematic history divided into a military, a foreign, a traffic, a communicative, an industrial, an educational, an academic, and a religious affairs. Otherwise, we had better make a chronological table which is divided the historical facts occurred in an special period into some kinds of categories or into a region, a race, and a nation.
