Objectives: The purpose of this study was to suggest a scientific method for measurement of children's growth development. Ultrasonic image of calcaneus bone has some advantages that it is harmless to human body and apply a new imaging analysis algorithm. it can be used for the diagnosis of growth analyzed the opening degree of growth plate and bone density. Methods: This clinical study have been carried out with the 57 case(male 24, female 33) of the children aged 5 to 14 years old who visited in Department of Pediatrics, Dongguk university Bundang Oriental Hospital. Bone maturity is measured by the opening degree of growth plate and bone density in ultrasonic image of calcaneus bone This study were designed to investigate the relationship of the development of children and the calcaneus bone maturity. Result: The opening degree of growth plate was no change in aged 5-10 years for male and 5-9 years for female but decreased significantly from aged 11 years for male and 10 years for female. the bone density was no change in aged 5-12 years for male and 5-11 years for female but increased significantly from aged 13 years for male and 12 years for female. it was confirmed that bone maturity in female is more rapid than in male. The opening degree of growth plate of claclneus bone was correlated with age, height, weight. The bone density was correlated with age, height, weight, BMI in this suudy(P<0.001) Conclusion: The opening degree of growth plate and bone density of calcaneus bone are sufficient diagnostic worth as an index to predict adolescent growth.

This study aims both to analyze view resources of on agricultural village and its original view image in order to establish indexation and the direction of development and to present assessment model of agricultural view for expectations in plan change for and improvement of agricultural view and alternative valuation. To do this, I selected four agricultural villages as the case areas for this study and examined view resources and their residents' consciousness through a questionnaire and investigated the image preference degree of agricultural village view and view preference. The results of this study are as follows: 1. The newly-introduced artificial view elements, according to development, are a hindrance element of agricultural view; as such Commercial buildings and transmission towers show the highest frequency and are increasing. The problem is that development is being made without any systematic plan. 2. In the examination of images of agricultural villages, the traditional ones are 2.82 on average, which means the view is modern; the natural ones are 3.3 on average, which indicates natural images; the agricultural ones are 3.67 on average, which emerge as agricultural images. View preference degree is 3.34 on average, which is usually good. 3. It is proved that all of the variables of type of location form and view image increase the degree of view preference; size in causal relation can be identified by parameter estimate; that Type I. image variables of agricultural-ness contribute to the dependent variables, view preference degree. 4. It is identified that view preference degree according to location from emerges mountain type, champaign type, and suburbs type in order of preference.

The strength development of concrete is influenced by temperature and cement type which greatly affect hydration degree of cement. There is not pertinent concrete strength management method in korea. There are several methods for estimating the in-place strength of concrete. One such method is the maturity concept. The maturity concept is based on the fact that concrete gains strength gradually as a result of chemical reactions between cement and water; and for a specific concrete mixture, strength at any age and at normal conditions is related to the degree of hydration. The rate of hydration and, therefore, strength development of a given concrete will be a function of its temperature. Thus, strength of concrete depends on its time-temperature history. The goals of the present study are to investigate a relationship between strength of high-strength concrete and maturity that is expressed as a function of an integral of the curing period and temperature and predict strength of concrete.

The purposes of this study were to examine the alliance success factors (ASF) and the business environments (BE) from the textile companies' viewpoint, to examine the differences in ASF and BE by firm characteristics, and to examine the relationships between BE and ASF. BE included the degree of market competition and the firm's competitive advantage, and firm characteristics included type of business, the number of employees, and length of business operation. Data were obtained from 155 textile companies in Daegu and Gyeongbuk regions in Korea via a questionnaire survey. Four factors including relationship capital, organizational support, alliance management, and alliance performance were extracted from ASF, and resources, product development, and marketing were extracted from the firm's competitive advantage. There were differences in product development by the number of employees and in the degree of market competition by type of business. The degree of market competition had significant relationships with all of ASF while the firm's competitive advantage differed in the relationships.

Recently. the properties of early-age concrete are increasingly important because these properties directly influence the behavior of early-age concrete structures including stress and cracking behavior. Nevertheless, the studies on early-age concrete are limited to strength and temperature development. The purpose of present study is to propose a simple and rational method which can predict the stress and strain behavior of young age concrete. A series of test have been done to measure the temperature development, strains and stresses in concrete members. The concept of equivalent age was used to define the degree of hydration and this degree of hydration was used to calculate the strength and elastic modulus. The present study indicates that the calculated stresses correlate fairly well with measured stresses. The consideration of critical degree of hydration in calculating stresses gives more accurate results. The present study provides useful method and data in evaluating early-age behavior of concrete structure.

Recently, the digital circuit technique has had great success and gained importance in all industries. For the measurement of degree of freshness of plant and animal's tissue, many devices has been developed. But it's data was inaccurate and it had difficulty in making database because it was depend on analog circuit technique. The purpose of this paper is the development of a device based on digital circuit for measurement of freshness degree of wet fish such that its accuracy is very trustworthy and it can be measured in a short time. The device is developed by using micro-computer with some interface modules of A-D/D-A converter and digital circuit with IC modules and its effectiveness has been evaluated through two experimental results of electrical Q-value test and chemical K-value test.

Experimental approaches on the effectiveness of thimerosal to control growth of Nosema apis (Zander, 1909) were carried out in the rearing honey bees. The rearing honey bees were artificially infected with various levels of spore isolated from local honey bees. The results obtained were summarized as follows: 1. In the experiments of therapeutic chemicals for Nosema disease, 0.01% and 0.02% thimerosal of sucrose-honey mixture was the most effective agent but the each concentration of amprolium, furazolidone, hygiene, sulfadimethoxine and terramycin did not show the any effects 2. It showed very high therapeutic effectiveness (over than 90%) that the treatment of three times every other day after the treatment of three times consecutive every day with 0.01% thimerosal, or the treatment of three times consecutive every day with 0.02% thimerosal. 3. When 0.02% thimerosal was administered three times consecutive every day to honey bees at the 4th day before artificial inoculation of N. apis, it showed very high degree (100%) of prevalence control effectiveness, and it also showed high degree (over than 90%) in administration at the 7th day before, and over than 80% at the 10th day before. Then authors found that thimerosal has the prevalence control effectiveness as well as the treatment effectiveness. 4. In the rearing honey bee colony, 0.02% thimerosal showed the high degree (over than 80%) of therapeutic effectiveness with the various levels which contained from the light decree of infection to the severe degree of it.

The purpose of this study is to provide basic information necessary for improving the satisfaction and quality of leisure life and thereon propose better leisure life programs in accordance with gender. For the purpose, this researcher made a questionnaire survey of 560 persons between July and December 2003 to know the trend and satisfaction of their leisure life in accordance with their gender. Results of the study can be summarized as below; First. the extent to which the surveyed persons participated in leisure life was highest in terms of other leisure activities, followed by self-development. viewing activities, sports activities and journey in order. The satisfaction of leisure life participation by those surveyed persons was scored 3 or over in average, meaning 'generally satisfied'. The time of leisure life participation was most spent in other leisure activities and self-development. Expenses of the participation were highest in terms of other leisure activities. followed by self-development and viewing activities in order. Second, differences in sub-areas of leisure life were analyzed in accordance with gender to show that the degree and time of participation in viewing activities and self-development, expenses of sports activity participation and the degree of participation in journey and others were significantly different between the opposite sexes which were surveyed here. Men were higher in the degree, time and expenses of the participation than women. Third. effects of gender on the satisfaction of leisure life as a whole were determined here to show that men were higher in such satisfaction when they were more satisfactorily participating in sport activities while in case of women, when they were spending more time in sport activities. Women showed a higher satisfaction of leisure life as a whole when they were more frequently and satisfactorily participating in other leisure activities. Based on these results, the researcher proposed effective leisure life programs in accordance with gender.

The purpose of this study was to explore the relationship between agricultural insurance, agricultural loans, and the agricultural industry and find ways to consolidate and improve the interactive development between these three systems. We collected relevant data from 2009 to 2019 in 15 provinces of China and constructed a coupled coordination model to analyze the data. The results are as follows: First, the eastern part of China was ahead of the central and western parts in terms of agricultural loans and the agricultural industry, while the western part was ahead of the central and eastern parts in terms of agricultural insurance. Second, the coupling degree of the three systems in all 15 provinces reached an extremely high level. Third, all 15 provinces showed an overall continuous rise in coupling coordination degree. In 2019, eight provinces reached the medium-level coupling coordination development, and seven provinces were in a state of barely coupling coordination development. The three systems formed a mutually reinforcing relationship and basically entered a state of coordinated development. Finally, there was a great development gap between different regions of China concerning the coordinated development of the three systems, therefore, innovative development is urgently needed to further promote the coordinated development level.
