The "Child Care and Education Policy(CCEP)" is important because it is responsible for providing 'care and education service' to young children in their 'most sensitive period' of human development. In reality, however, children's rights can only be sanctioned by adults and their rights are recognized at the level of abstraction. This study analyzes the 'Child Edu-care Act(CEA)' first enacted in 1991 from the 'perspective of children's rights', especially in terms of the rights of infants and preschoolers. In order to assess the CEA's "children's rights guarantee level", this study developed a number of standards based on the "UN Convention on the Rights of the Child(CRC)" and other documents. The results revealed that "children's rights guarantee level" was assessed against 4 categories ('Right to Survival and Development', 'Right to Welfare', 'Right to Education', and 'Right to Proper Care'), and the CEA(1991) was found to have a high guarantee level although it was enacted before Korea's ratification of the CRC. The results of this study can serve as a useful reference point for detailing children's rights and suggesting regulation standards for the CCEP.

This paper presents a CAD program develpoed on a microcomputer in order to support graphic and computational assessment of ergonomic problems associated with the design of a man-in-cab system. The program is coded to help workspace designers with ergonomic evaluations needed in the design stage. This paper proposed a biomechanical -ergonomic evaluations needed using man and workplace models. The human model is developed to have dimensions obtained from the Korean anthropometric data reported in 1992. Its graphical representation is based on a wire-frame model but, whenever necessary, body segments can be represented by a solid model with hidden line/faces removed and shaded. Workplace models are presented for cabs of the excavator, one of the most popular construction vehicles. A workplace model consists of an operator seat, a steering wheel. two control levers, two pedals, and a control panel. The workplace elements can be modified in their sizes, positions, and orientations by changing the reference point and design parameters. An algorithm for the view test is suggested and loaded to provide a visual evaluaiton of the overall layout of a workplace model.

Many studies regarding construction safety management have been conducted. However, it is insufficient to research on external construction site. As a result, ordinary people around the construction site have injured and have a negative view when they think construction industrial since it has regarded having an overfull industrial accidents on media. To break the stereotype and prevention of accident on construction industry have been emphasized at this point in time, it is necessary to establish a comprehensive safety management system which is considered not only internal safety management but also external safety management. Therefore, the objective of this study is to develop the human accident risk quantification model by utilizing the third party payout data which occurred by incomplete safety management on external construction site. This study is conducted as a basic study for developing safety management manuals on internal·external construct site. In the future, it is expected to be used as a reference.

Objective: The purpose of this study was to develop a goal setting method for increasing the probability of a holed in a side inclined putting stroke. Method: Three-dimensional video data was recorded at a frequency of 120 hz per second after synchronizing 19 infrared motion capture systems (Qualisys, Gothenburg, Sweden). Putting green used a polycarbonate plate ($1.2{\times}2.4{\times}0.01meter$) with coefficient of friction (${\mu}=0.062$) and a real curve of the actual hole. Results: The velocity ratio between the club and the ball was 1:1.6 under various ball speed conditions in this study. The overall position of the break is 1 m to 1.4 m from the point where the ball leaves. If there is a slope, the ball follows the target line by the straightening force, and when it reaches 1 m position, the straightening force decreases by 30~50% and reaches to the deviation (break) point which is severely influenced by the slope. From here, the ball is aimed in a direction other than the target, and the size is affected by the slope. Conclusion: If there is a side slope, the ball moves away from the straight line, and the larger the slope, the closer the break point is to the starting point of the ball. Therefore, it is necessary to calculate the degree of departure according to the slope carefully, and it is preferable that the slower the speed is, the more the influence of the slope becomes. It is preferable to use the center of the hole as a reference when calculating the departure.

Sensory analyses of pork samples from leg muscles of female pigs raised in New Zealand (n = 17) were conducted using trained and untrained Singaporean panelists. The New Zealand pigs included three dietary groups, with one diet including animal products (NZA), and two containing plant products only (NZP & NZP+), with the NZP+ diet containing a supplement (0.614%) containing conjugated linoleic acid (CLA), selenium, and vitamin E. The New Zealand pork was also compared with Indonesian pork as local reference samples (n = 6). Pork samples from the NZA group had the highest score for mutton flavour and aftertaste, and the lowest score for brothy aroma, brothy flavour, meaty flavour, lightness and juiciness by trained sensory panels. Samples from NZP and NZP+ were similar except the NZP+ group had a stronger stale flavour than the NZP group (1.34 vs. 0.57 on a 100-point scale; p<0.05). The first and second functions of a discriminant analysis based on trained-panel scores for 14 attributes accounted for 95.4% of the variance, with function 1 (83.7%) being related mainly to mutton aroma, mutton flavour and aftertaste. Based on a 20-member untrained panel, the NZA pork had the highest mutton aroma and mutton flavour intensities (p<0.01) and aroma and flavour that was less acceptable than that from the NZP group (p<0.05). The acceptability scores of Indonesian pork were not significantly different from those of New Zealand pork, but its scores for mutton aroma and mutton flavour were significantly lower than NZP. Overall acceptability was positively associated with acceptability of aroma (r = 0.906), juiciness (r = 0.888), and tenderness (r = 0.904), but negatively associated with intensities of mutton aroma (r = -0.478) and flavour (r = -0.551).

The purpose of this study is to provide fundamental information for standardization of 3D body measurement. This research analyzes errors occurring in the process of extracting body size from 3D body scan data. First, as a result of analyzing basic state of the 3D body scanner's calibration, the point number of each section was almost the same, while the right and left as well as the front and back coordinates of the center of gravity are not, showing unstable data. Nevertheless, the latter does not influence on the size of cylinder such as width and circumference. Next, we analyzed point coordinates variations of scan data on a mannequin nude by life casting. The result was great deflection in case of complicated or horizontal sections including the reference point beyond proper distance from centers of four cameras. In case of the mannequin's size, accuracy proves comparatively high in that measurement errors in height, width, depth, and length dimension occurred all within allowable errors, only except chest depth, while there were a lot of measurement errors in a circumference dimension. Secondly, analysis of accuracy of automatic extraction identification program algorithm presented that a semi-automatic measurement program is better than an automatic measurement program. While both of them ate very acute in parts related to crotch, they are not in armpit related parts. Therefore, in extracting of human body size from 3D scan data, what really matters seems to parts related to armpits.

Research on children should be perferably made in reference with the past thinking if it is to be affirmed by the present and to predict the future. In this respect, Buddhism, which is one of the major original thinkings in the Orient as well as the most influential religion upon Koreans daily lives and attitudes, deserves to be researched in the light of education of children. In this thesis, I have made a trial to delve into the original Buddhistic scriptures to find out Buddha's outlook on home children and arrived at the following conclusions: 1. Concerning human development stages, Buddha regarded the starting point of human life from fertilization instead of birth, even at that ancient time, and the fetal life was devided into 4, 5, or 8 stages. 2. In spite of the numerous scriptures by Buddha, very little is written about children, and even these teaching did not regard the child as an independent entity. In addition, since Buddha was a person of superior enlightenment, he did not regard the age of human beings as of great importance. 3. On the relationship between parents and children, Buddha warned the extra ordinary attachment of parents toward children, because such attachment would be an obstacle in the search of truth. This idea was originated from his thought that the relationship between parents and children was not a single fixed one but of unlimited variation through numerous life times of reincarnation. This idea gives some illumination upon the problems of today's education where parent's exclusive attachment to their children and over-protection are hindrance for successful education. 4. Buddha put emphasis on parents' social duty, by which he meant that parents should care and accept not only their biological children but all children and all living things as if they were their own children. 5. Regardeding the children's role to their parents, Buddha taught that children should respect and support their parents under any condition. Buddha also emphasized that true filial piety was to help parents to improve their religious status by helping them attain the truth, morality, and wisdom. It is my intention to investigate Buddha's View tin children of entering pristhood.
