A variety of methods for measuring the velocity from an image sequence use the relationship between the spatial and temporal gradients of image brightness function. In most situations, an additional constraint is required because the velocity is not determined uniquely by a above relationship. Horn and Schunch proposed a constraint that the velocity field should vary smoothly over the image. This requirement, however, forces the velocity field to vary smoothly even across motion boundaries. To complement this probe, Nagel introduced and 'oriented smoothness' constraint which restricts variations of velocity field only in directions with small or no variation of image brightness function. On the other hand, Paquin and Dubois proposed a different type of constraint that the velocity is constant in a small area of image. But, this constraint also creates difficulties at motion boundaries which large variations in velocity field often occur. We propose the method to overcome these difficulties by utilizing the information of discontinuities in image brightness function, and present the experimental results.

This report studies what connections was between Ethnic education movement in Bukkando and natural and human knowledge environment as a way to complement total absence of studying Anti-Japanese Movement at the Geographic levels. The summary is as following: At first, the Korean villages, where almost all spread the national schools, so there was a very close relationship. Both from a Longjing as the central plain area to the proliferation of surrounding areas. Second, schools that was adjacent to trunk road were given a great deal of weight on the connection with traffic. After that, however, it decreased gradually. Third, the national schools suffered the dual intervention from China and Japan, experienced a difficult development process. the schools which built by Japan were spreaded areas where concentrate the schools which built by Japan were spreaded areas where concentrated many national schools, both have a close relationship. before 3.13 movement, the distribution of schools that established by the Chinese mainly spreaded the areas concentrated national schools. But, after the 3.13 movement, it appeared a tendency to spread to the Korean people area where relatively dwelled a few people.
Narrative runs through the entire human life. 'Narrative' is a means of understanding and experiencing human life. The past, the present and the future are not disconnected. The past is open to the future. The future defines the meaning of the past, and the past rreturn as the horizon of life. Past, present and future temporality functions as a Narrative. Records reproduce the past time as Narrative, and recount the past according to reading behavior. Reality and records complement each other with a cyclic and dialectic structure. This paper examines the relationship between reality and records. This paper applies Paul Ricoeur's Hermeneutics to records as a tool to examine the relationship between reality and record. We want to look at how records interpret and relates to reality, and how social justice of collective memory should be should be achieved against them.
Growth in the outsourcing market signals that firms of all sizes believe outsourcing will ultimately deliver many benefits and conveniences. But there are not many firms satisfied with the results of outsourcing. What is more, previous researches were fragmentary analyses focused on specific variables of outsourcing such as sourcing decisions, partnership rather than comprehensive analysis. Thus, they could not propose general systematic methodologies applicable to the real situation. To solve these problems, we developed an integrated theoretical framework that considered both contract with the hard side and trust with the soft side from a contingency viewpoint and tested this model using 143 data of Korean companies executing outsourcing. In addition, we examined how situational factors(outsourcing task complexity and outsourcing management competence) affects each path in the research model. The results of this study are as follows. First, it was proved the theory that trust is not a substitute for contract but its complement. Previous empirical studies on outsourcing success factors were focused on the establishment of successful partnership on the assumption that trust can replace contract in many situations. According to the results of our empirical analysis, however, contract and trust were in a mutually complementary relation with each other and their emphasis was different. Furthermore, different from previous researches, it was found effective to use trust as a supplementary tool and contract as a main means in outsourcing management strategy. Second, this study provided an integrated view that sees both contract and trust from a contingency viewpoint in theoretically reestablishing the relationship between contract and trust. Previous researches leaned to specific variables or theory-centered fragmentary analysis, but this study proposed a more practical and integrated research model and tested its effectiveness. Based on the results, with the model, decision makers are expected to scrutinize outsourcing situation more closely and to have a practical insight to the situation. Third, it was found that contract mechanism and trust building do not have a direct effect on outsourcing performance but relationship management intensity mediates the effect of contract mechanism and trust building. This is considered significantly meaningful to outsourcing partners who have believed that outsourcing would be successful if a contract is made properly or trust is built. Lastly, the path from trust building to relationship management intensity was moderated by informed buying, as the path coefficients from trust building to relationship management intensity varied by the degree of informed buying competence.

Patients of chronic hepatic diseases(n=107) including chronic hepatitis caused by hepatitis B virus infections(n=31), liver cirrhosis(n=53), and hepatocellular carcinoma(n=23) were examined to ascertain genetic relationship between chronic hepatic diseases and histocompatibility antigen. Peripheral blood lymphocytes were separated from whole blood by the method of Ficoll/Hypaque gradient. Total 54 histocompatibility antigens(class I antigens: 41, class II antigens: 13) were analysed by performing of complement dependent microlymphocytotoxicity method using Terasaki's and Catholic Medical College tissue typing plates. HLA antigen frequencies were compared with those of 661 normal controls. The following results were obtained: 1. HLA antigen frequencies of HLA-Bw46, -Bw76, -Cw1, -Cw6, and HLA-DR8 in chronic hepatitis patients were shown to be higher than those in controls(P<0.01). 2. HLA antigen frequencies of HLA-Bw46, -Cw7(P<0.01), and HLA-B37, -Bw58, -Cw1, -MT1(P < 0.05) in liver cirrhosis patients were shown relatively higher frequencies than those in controls. 3. In patients with hepatocellular carcinoma, antigens of HLA-A1, -A26, -Cw3, -Cw7 and HLA-DR6 were dominantly detected. 4. There were negative associations with HLA-Cw4, and -DR4 in patients of chronic hepatic diseases(P < 0.05).

Membranoproliferative glomerulonephritis type II(MPGN II), also called dense deposit disease, was first described by Berger and Galle in 1963. The diagnosis of MPGN II is based on electron-microscopic finding of an intensely electron-dense substance which replaces the lamina densa of the glomerular basement membrane. Although the etiology and pathogenesis of MPGN II are unknown, it frequently progresses to end-stage renal failure. Typically in MPGN II, hypocomplementemia due to activation of the alternative complement pathway is present. In addition, the association of MPGN II with partial lipodystrophy and complement abnormalities is well documented. The relationship between these associated features and the patient's renal functional outcome is not clear. With respect to the therapy for MPGN II, an alternate-day prednisolone regimen was shown to be effective. Various treatment modalities, including immunosuppression with corticosteroids, cytotoxic drugs and cyclosporin A, anticoagulants and antiplatelet therapies are used, either alone or in combination, with varying degrees of success. The purpose of this paper is to present a case of MPGN II from a 7 years old girl with paroxysmal supraventricular tachycardia(PSVT).
The purpose of this study was to determine biochemical parameters related to protein and immunity. Subjects were 125 preschool children(M:69, F:56) residing in low income area of Seoul. Mean serum total protein of the children aged 6 was 7.3g/dl which was significantly higher than 6.6g/dl of the group aged 3. The mean serum albumin was 4.7g/dl for 3, 4, 5 age group, and 4.9g/dl for 6 age group and there was no significant difference. Serum retinol binding protein(RBP) is used as a sensitive indicatior of protein, because it tends to fall rapidly in response to protein status and respond to quickly dietary treatment. Mean RBP for each group(3, 4, 5 and 6 age group) were $2.5\mu{g}$/dl, $2.9\mu{g}$/dl, $2.7\mu{g}$/dl, $3.0\mu{g}$/dl. The Proportion of children whose RBP was than $2.6\mu{g}$/dl was 15.9%, 19.2%, 24.3% and 16.7%, respectively. The 24-hour urinary excretion of hydroxyproline was 7.9mg, 14.6mg, 11.7mg and 11.8mg for each group and the mean excretion of all children was 12.2mg/day. Children aged 3 were excreting significantly lower amount of hydroxprolinc per day than the children aged 4. The mean hydroxyproline index were 2.18, 2.39, 2.52, 2.80 for each age group and the mean of a group aged 6 was significantly higher than that of the group aged 3. The proportion of children assessed as malnourished and impaired growth(hydroxyproline index <2.0) was 18.8%, 4.9%, 2.5% and 4.3%, respectively. The nutrients which showed significant relationship with protein and immunity parameters were niacin, vitamin C and calcium. Vitamin C showed significant positive relationship(p<0.05-p<0.01) with serum RBP, total protein and globulin. The triceps skinfold thickness was significantly and positively correlated with serum globulin. Serum IgG showed significant positive relationship with height, weight, girth of chest and midarm circumference(p<0.05-p<0.01).
This study was conducted to analyze the relationship between the practice of aerobic exercise and the prevalence and risk of arthritis with comorbid chronic diseases. For this study, the National Health and Nutrition Examination Survey 2017-2019 data were used and 17,356 people were selected as subjects. The relationship between the practice of aerobic exercise and the prevalence and risk of arthritis according to demographic characteristics and chronic diseases was analyzed by the chi-square independence test and Breslow-Day test. While the rate of aerobic exercise was low among women, the elderly, the low-income group, the low-education group, and people living in rural areas, the prevalence and risk of arthritis were relatively high. And in the chronic disease-positive group, those who practiced aerobic exercise had a relatively lower prevalence and risk of arthritis than those who did not. In particular, the practice of aerobic exercise was an effective complement in reducing the prevalence and risk of arthritis in people with high blood pressure, diabetes, and dyslipidemia. Therefore, the practice of aerobic exercise such as walking, slow running, and aerobic dance should be recommended in terms of the preventive medicine and health care to people who are in the group with a high prevalence of arthritis in demographic characteristics and people who have comorbid chronic diseases.

In this study, to identify single nucleotide polymorphisms (SNPs) associated with meat quality in Berkshire pigs, we performed RNA sequencing. A non-synonymous SNP (nsSNP) in the Complement component 9 (C9) gene was identified, and the association between meat quality traits and the C9 genotype was analyzed. The nsSNP in the C9 gene was located at c.942 G>T. In the dominant model, significant associations were observed between the SNP and meat quality traits such as CIE L, collagen content, moisture level, and $pH_{24h}$, whereas in the co-dominant model, significant associations were observed between the SNP and CIE L, collagen content, and protein content. In the recessive model, a significant association between the C9 genotype and the collagen content was observed. In addition, we identified the significant relationship between the C9 genotype and meat quality according to sex. These results indicate that the C9 SNP can be used as a genetic marker for improving pork quality.
The need for ready-to-wear clothing increases as the problem comes to arise from the fit of custommade clothing due to the characteristics of middle-aged women's somatotype. At this point of time, a study on the realities of production of custom-made clothing in middle-aged women's clothing business firms is of very greatly significance. Therefore, this study was intended to identify the problem and improvements through the survey research of production of custom-made clothing in middle-aged women's clothing business firms and further present the plan for development of custom-made clothing business. The questionnaire was framed based on the contents extracted from the preliminary questionnaire research for the pattern section chief of each business firm. Collected data were statistically processed using the SPSS 10.0 Windows program. As a result, the following findings were obtained: 1. The target age of the middle-aged women's clothing business firms ranged from more than 45 years to less than 50 years of age. Clothing business firms much made inroads into the ready-to-wear clothing market largely in the 1980s and the 1990s. Their active entry into the custom-made clothing market occurred in the 1970s and the 1980s. 2. In terms of the clothing production method of middle-aged women's clothing firms, some private boutique and designer brand clothing firms entered the clothing market with a focus on custom-made clothing in the beginning of its organization and introduced the production method of ready-to-wear clothing in accordance with changes in production methods and consumers' needs and wants. National brand clothing firms manufactured clothing with a focus on ready-to-wear clothing from the beginning of its organization, but at last they manufactured both partial custom-made and whole custom-made as the problem arose from ready-to-wear clothing. Seeing that their clothing production showed the ratio readyto-wear to custom-made clothing of 2.58:1. And it was found that the manufacture of ready-to-wear and custom-made clothing took into consideration the great difference in the pattern, size and design plan. The research of the clothing production process showed that whole custom-made and partial custommade were distinguished according to whether or not the sample was presented. 3. The ready-to-wear pattern of middle-aged women's clothing firms were used with a focus on the 'patternmaker-developed pattern' and company-developed pattern'. Most clothing businesses produced clothing in 4 to 5 basic sizes, which is found to be insufficient to complement the physical characteristics of middle-aged women with many specific somatotypes. In the pattern of custom-made clothing, the 'pattern of ready-to-wear were applied' or the 'customized pattern was developed'. Actual measurements were most used as the size of custom-made, and accordingly it is predicted that the level of satisfaction is higher with the fit of custom-made clothing than that of ready-to-wear. The selling place and the head office showed the similar percent as the place for measuring the size of custom-made clothing. Size measurers were mostly the shop master. And it was found that most clothing business firms had a problem when the measured size was applied to the pattern. Accordingly, it is necessary to provide education on size measurement for shop masters. 4. It was found that in the middle-aged women's clothing firms, the pattern correction of the length of sleeve, jacket and slacks occupied the highest percent. Accordingly, it is necessary to provide for the size system to complement the accurate somatotype characteristics of middle-aged women. 5. In custom-made clothing customer management, most firms engaged in customer somatotype management through size management. They provided customers with commodity information by informing them of the sales and event period and practiced human management for customers by maintaining the get-together and friendly relationship. 6. Middle-aged women's clothing businesses responded that it would be necessary to improve the fit of custom-made clothing and complement their pursuit for individuality as the plan to improve its quality. In consequence, it suggests that middle-aged women's clothing businesses should provide middle-aged women with the clothing of better-suited size and refined design. Middle-aged women's clothing businesses responded that it was the most urgent task to form the custom-made clothing manufacturing team as the plan to expand the custom-made clothing market, which is identified as their emphasis on the systematized production of custom-made clothing.
