The purpose of this study was to introduce the writers, such as Kita Mura, To-Koku(北村透谷)and Kawa Kami, Bi-Zan(川上眉山), who committed suicide in the modern age of Japan, and to investigate their suicide. The result of this study suggested that the suicide motives of Kita Mura were the frustration and the loss of life activity come from the gap between his ideal and reality. The factors which Kawa Kami committed suicide were considered as the maladjustment to rapidly changing socicety, the pain of creative writing, and that of living affairs. By the way, as the motive of suicide is very complex and its behavior is individual, a more scientific and objective investigation should be conducted in further reseatrch.

尹起英,李夏白,朴鍾茂 한양대학교 의과대학 1985 한양의대 학술지 Vol.5 No.2

Erythropoietin (Ep) is a glycoprotein hormone of mostly renal origin that stimulates red cell production in response to tissue hypoxia. Serum Ep activities provide important clinical clues in making the differential diagnosis of some types of anemia and polycythemia. The study was performed in order to evaluate the diagnostic value of serum Ep activities in 29 normal subjects, 43 anemic patients and 15 secondary polycythemia patients and to find out the relationship between hemoglobin concentration and serum Ep activities in these patients using the Enzyme Immunoassay with Second International Preparation for Ep. The results obtained were as follows: 1. Ep activities in sera from 29 normal subjects among children ranged from 11 to 72 mU/ml, with a mean of 37.10±16.54 mU/ml. There was no significant difference between the serum Ep activities in male and female subjects (p>0.05). 2. Ep activities in sera from 22 patients with iron deficiency anemia ranged from 48 to 400 mU/ml, with a mean of 153.5 mU/ml which was about 4 times higher than normal value. Ep activities in sera from 18 anemic patients with acute infection ranged from 35 to 290 mU/ml, with a mean of 134.05 mU/ml which was about 3.5 times higher than normal value. Ep activities in sera from 3 patients with aplastic anemic ranged from 620 to 840 mU/ml, with a mean of 720 mU/ml which was about 20 times higher than normal value. 3. Ep activities in sera from 15 patients with secondary polycythemia ranged from 12 to 140 mU/ml. In 10 of 15 patients, the mean Ep activities was 87.50 ± 25.60 mU/ml, which was about 2 times higher than normal value. In 5 of 15 patients, Ep activities were within normal range as a mean of 35.80 ± 17.23 mU/ml. In summary, a significant negative correlation was found between the hemoglobin concentration and the logarithm of the serum Ep activities in 43 patients with anemia (r=0.73, Y=3.6766-0.1802x) and Ep activities in patients with aplastic anemia was higher than those in patients with iron deficiency anemia at comparable hemoglobin concentration. From the above results, it was concluded that serum Ep activities in anemic patients are not only inversely related to the hemoglobin concentration but also to the activity of the erythroid bone marrow. While no significant correlation was found between hemoglobin concentration, hematocrit percentages and Ep activities in 15 patients with secondary polycythemia (r=0.18, 0.39 respectively).

이기안,이종수 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.12

A series of tensile tests were carried out on a B2-type b-CuZn alloy in the temperature range, room temperature to 400oC at three different strain rates (10^(-5) sec^(-1), 10^(-4) sec^(-1), 5.2x10^(-2) sec^(-1)). The stress-strain curves could be divided into three types. Type I indicates a remarkably linear sustained work hardening to fracture, type II work hardening and subsequent necking, type III yield drop behavior and stress saturation, respectively; corresponding to the insensitive yield stress region, anomalous yield stress region, and yield stress decreasing region, in the yield strength vs. temperature graph. The ultimate tensile strength basically decreased as temperature increased, only showing characterized strength hump-up region just below T_(p). The fracture mode was changed mainly from transgranular at room temperature to intergranular at high temperatures. The elongation increases with increasing temperature in region I, and then slightly decreases in region II (anomalous yield stress region). When the specimens were tensile-fractured at high temperatures (region III, above Tp), the elongation drastically increased with decreasing strain rate, for instance from 12% at 5.2x10^(-2) sec^(-1) to 87% at 10^(-5) sec^(-1). The dependence of ductility on strain rate was mainly attributed to the thermally activated <100> dislocation climb, inducing stress relief at the grain boundaries, as evidenced by microvoids at grain facets.

β-CuZn 합금의 항복강도 이상거동에 미치는 변형률 속도와 온도의 영향

A series of tensile and load relaxation behaviors in B2 type β-CuZn alloy have been examined to clarify the strain rate & the temperature dependence of yield stress anomaly. It has been found in tensile tests that the region showing anomalous peak of yield stress moves to a higher stress and higher temperature region with increasing strain rate. The anomalous yielding region below peak temperature(T_p) revealed slightly positive strain rate dependence, while the region above T_p showed considerably positive strain rate dependence. The slip lines formed below peak temperatures (T_P) were clearly visible with naked eye(coarse slip lines), and became finer near T_p(fine slip lines), while they disappeared completely above T_p. Based on the different tendency of temperature and strain rate dependence of anomalous yielding as the above-mentioned results, two types of deformation modes were suggested and incorporated into the flow curve analysis, which was in accord well with the experimental results. The slightly positive strain rate dependence of yield stress anomaly indicated that the yield stress anomaly in β-CuZn alloy mainly seemed to be attributed to the vacancy hardening.

金鍾悟,林榮彦,金澤基 충남대학교 공업교육연구소 1983 論文集 Vol.6 No.1

In order to clarify the magnetization mechanism in amorphous materials, the dependence of magnetic and electrical properties on composition and temperature in amorphous Fe_80(Si_(1-x)B_x)_20, (Fe_(1-x)Ni_x)_80B_20 and (Fe_(1-x)Ni_x)_77Si_10B_13 alloys have been studied systematically. The results are as follows; 1) The density in amorphous alloys is directly proportional to the concentration of alloying elements. The density in amorphous Fe_80(Si_(1-x)B_x)_20 alloys decreases linearly with increasing B concentration, and those in amorphous (Fe_(1-x)Ni_x)_80B_20 and (Fe_(1-x)Ni_x)_77Si_10B_13 alloys increase linearly with increasing Ni concentration. 2) The ratios of B_r/B_s from the B-H loop in amorphous Fe_80(Si_(1-x)B_x)_20, (Fe_(1-x)Ni_x)_80B_20 and (Fe_(1-x)Ni_x)_77Si_10B_13 alloys show more than 95% and the coercive forces are hardly related to the concentration of alloying elements. 3) The average magnetic moment per atom of transition element in amorphous Fe_80(Si_(1-x)B_x)_20 alloys increases with increasing B concentration, and those in amorphous (Fe_(1-x)Ni_x)_80B_20 and (Fe(1-x)Ni_x)77Si_10B_13 alloys decrease with increasing Ni concentration. This means that the magnetization mechanism in amorphous alloys can be explained by Donor model. 4) Curie point in amorphous (Fe_(1-x)Ni_x)_77Si_10B_13 alloys decreases with increasing Ni concentration. 5) The resistivity of amorphous state in Fe_80(Si_(1-x)B_x)_20, (Fe_(1-x)Ni_x)_80B_20 and (Fe_(1-x)Ni_x)_77Si_10B_20 alloys is about 2 times larger than that of crystallized state. 6) The crystallization temperature in amorphous Fe_80(Si_(1-x)B_x)_20 alloys decreases with increasing B concentration, and those in amorphous (Fe_(1-x)Ni_x)_80B_20 and (Fe_(1-x)Ni_x)_77Si_10B_13 alloys decreases with increasing Ni concentration.

On the basis of a theoretical tenet that voluntary sports commitment is a result of participation motivation both inherent in and extrinsic to the participant, a survey research was conducted with 664 university students sampled from six major universities located in the metropolitan Seoul area. It was theorized that the intrinic motivation for sports commitment is intimately associated with the relative degree of sport socialization which is postulated to be highly dependent upon personal attributes (e.g., sex, sport aptitude, interest, attitude, etc.) as well as upon influences from parents, peers, and teachers during the maturing ages, i.e., elementary and secondary school ages. A self-report sports commitment questionnaire along with a sport socialization scale assessed 1) the present levels of sports commitment of respondents and 2) the degrees of sport socialization as well as socializing factors including personal attributes and influences from significant others. Data analysis(using ANOVA, multiple regression analysis, etc.) revealed that: 1) a very low percentage of respondents practices sports and exercises; 2) even the sport-committed group is engaged mostly in a limited kind of sports learned at the schools, instead of such life-time oriented individual and dual sports as bowling, badminton and jogging, with the frequency and duration being low and short; 3) the main reasons for participating in sports are such extrinsic factors as improvement of health and weight control, rather than pursuit of fun, enjoyment, achievement and win; 4) in contrast, the main reasons for not participating in sports are lack of interest, concern, and skill as well as lack of time and facilities; 5) the sports commitment is significantly influenced by the degree of sport socialization which, in turn, is determined, to a great degree, by such socializing factors as personal interest, attitude, sex, birth place, and influences from significant others. In order to promote mass sports, thus, these results, taken together, suggested a need for more emphasis on school physical education directed toward enhancing the awareness, interest, and attitude toward sports along with the provision of space and facilities for mass sports from the governmental standpoint.

Tryptic Digestion and Cytochalasin B Binding Assay of the Human HepG2-Type Glucose Transporter Expressed in Spodoptera frugiperda Clone 21-AE Cells

이종기 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.1

The number of sites at which a protein can be readily cleaved by a proteolytic enzyme is greatly influenced by its three-dimensional structure. For native, properly-folded proteins both the rate of cleavage and number of sites at which cleavage takes place are usually much less than for the denatured protein. In order to compare the tertiary structure of recombinant HepG2 type glucose transporter with that of its native counterpart in the erythrocyte, the pattern of tryptic cleavage of the protein expressed in insect cell membranes was therefore examined. After 30 minutes digestion, a fragment of approximate Mr 19,000~21,000 was generated. In addition to this, there were two less intensely stained fragments of apparent Mr 28,000 and 17,000. The pattern of labelling was similar up to 2 hours of digestion. However, the fragments of Mr 19,000~21,000 and Mr 17,000 were no longer detectable after 4 hours digestion. The observation of a very similar pattern of fragments yielded by tryptic digestion of the HepG2 type transporter expressed in insect cells suggests that the recombinant protein exhibits a tertiary structure similar if not identical to that of its human counterpart. Also, the endogenous sugar transporter(s) present in Sf21 cells did not bind cytochalasin B, the potent transporter inhibitor. Therefore, the baculovirus/Spodoptera frugiperda (Sf) cell expression system could be very useful for production of large amounts of human glucose transporters, heterologously.

Purpose : To evaluate clinical usefulness of facial soft tissue thickness measurement using 3D computed tomographic images. Materials and Methods : One cadaver that had sound facial soft tissues was chosen for the study. The cadaver was scanned with a Helical CT under following scanning protocols about slice thickness and table speed; 3 mm and 3 mm/sec, 5 mm and 5 mm/sec, 7 mm and 7 mm/sec. The acquired data were reconstructed 1.5, 2.5, 3.5 mm reconstruction interval respectively and the images were transferred to a personal computer. Using a program developed to measure facial soft tissue thickness in 3D image, the facial soft tissue thickness was measured. After the ten-time repeation of the measurement for ten times, repeated measure analysis of variance (ANOVA) was adopted to compare and analyze the measurements using the three scanning protocols. Comparison according to the areas was analyzed by Mann-Whitney test. Results : There were no statistically significant intraobserver differences in the measurements of the facial soft tissue thickness using the three scanning protocols (p>0.05). There were no statistically significant differences between measurements in the 3 mm slice thickness and those in the 5 mm, 7 mm slice thickness (p>0.05). There were statistical differences in the 14 of the total 30 measured points in the 5 mm slice thickness and 22 in the 7mm slice thickness. Conclusion : The facial soft tissue thickness measurement using 3D images of 7 mm slice thickness is acceptable clinically, but those of 5 mm slice thickness is recommended for the more accurate measurement.
