There are so many study on Heumheum Sinseo as a lawbook. But the study on Heumheum Sinseo as investigation and forensic manual is uncommon. So this study was performed to find the value of Heumheum Sinseo as investigation and forensic manual. In Heumheum Sinseo, we could find the basic ideology of a sense of justice on humanitarianism and rationalism, and democratic thoughts on criminal law such as the presumption of innocence, speedy investigation clause and Limiting the admissibility of the confession. And so many scientific method on crime investigation are described in Heumheum Sinseo. We expect that this study serve as moment for us to be able to find it have 'practical' value to us.

Inheritance and concurrency are the primary feature of object oriented languages, and are especially important for code re-use. They provide maximum computational power and modeling power through concurrency of objects. But, concurrent objects and inheritance have conflicting characteristics, thereby simultaneously use of them causes the problem, so failed inheritance anomaly, which requires code redefinition of inherited methods to maintain integrity of objects. In this paper, to solve the inheritance anomaly problems we introduce concept of state abstraction, in which infernal states of encapsulated objects are made available from a part of object's external interface. And we design inheritance interface mechanisms which methods are inherited efficiently. In our scheme, we can solve the typical inheritance anomaly problems.

Computer programming has educational effect on improving high-level thinking abilities. However, students initially have to spend too much effort in learning the basic grammar and the usage model of programming languages, which negatively affects their eagerness in learning. To remedy this problem, we propose to apply the Scratch to a Game Developing Programming Class; Scratch is an easy-to-learn and intuitive Educational Programming Language (EPL) that helps improving the Meta-cognition and Self-efficacy of middle school students. Also we used the Demonstration-Practice instruction model with self-questioning method for activating the Meta-cognition. In summary, a game developing programming class using Scratch was shown to significantly improve the Meta-cognition of middle school students. However it was shown to insignificantly improve the Self-efficacy of girl students group.

In this study, we performed experimental studies on the educational programming languages of Dolittle and Robot to compare and analyze their effect on improving creativity. We formed three sixth grade classes, totaling 99 students, into a Robot class, a Dolittle class, and a general class that served as a neutral. The Dolittle class and the Robot class took ten programming lessons with specific hand-in operations, as well as feedback and discussion, during ten weeks. The experiment results showed that student creativity in the two programming classes improved more than that of students in the general class. Especially creativity of the students in the Robot class improved the most. Moreover, the mean creativity of the lower academic achievement group was slightly better than that of the higher group. This implies that there is no positive correlation between academic achievement and creativity.

The programming learning by using a robot may be one of the most appropriate learning methods for enabling students to experience the creative learning of future society by avoiding the existing stereotyped style educational environment, and understand and improve algorithm which is the basic fundamental of mathematics and science. This study proposed four types of items of errors which may occur during robot programming by elementary school students, and made elementary school students in the fifth and sixth grades learn robot programming after developing the curriculum for the robot programming. Then, the study collected and classified errors that had occurred during the process of learning, and conducted a comparative analysis of computer-based programming language which had been previously studied. This study identified that robot programming in elementary school was shown superior to existing computer-based programming language as a creative learning method and tool through the field experience.

Algorithm education that become at the base of thinking is emphasized from primary school. However, It is difficult to understand algorithm in elementary school students level. In this research, it considered curriculum that can teach universally to elementary school students by solution plan of problem. So we chose Scratch program with education data, because it is verified the effect in education of algorithm, and easy to control among EPL (Education Programming Language). It was composed curriculum so that interaction is accomplished through group activities to coincide in various level of students, and approached to the problem-solving center to emphasize important thinking process in algorithm education, and got educational value in relevant level of each student. According to validation of expert groups and surveys, we concluded the curriculum that is appropriate. The curriculum proposed in this paper can help to enhance the problem solving ability and the creativity.

This study was to investigate the speech sound production characteristics and evaluation aspects of preschool children through word test and connected speech test. For this, the authors conducted Assessment of Phonology and Articulation for Children(APAC) to 72 normal children(24 three-, four-, and five-year-olds each) and analyzed difference in percent of correct consonant(PCC) and intelligibility according to age and sex, correlation between PCC and intelligibility, and speech sound error patterns. PCC and intelligibility increased with age but there was no difference according to sex. The correlation was statistically significant in 5-year-old group. Speech sound error patterns were different in the two tests. This study showed that children's speech sound production varied according to language unit. Therefore, both types of tests should be done to grasp their speech sound production ability properly. This suggests that current standard to identify language impairment only by PCC of word level requires review and further studies.

As a 21C core skill, computational thinking has been focused recently, and computer programming education is popular in primary and secondary schools. This paper aims to analyze the computer programming learning results based on gender difference and verify the reasons causing the difference. In this research, we focused on students' abstract thinking level as a variable and used C programming language and the RUR-PLE. Also, in this research, we focused on the concept of abstraction, one of the main component of computational thinking. And then, we analyze 587 high school students' abstract thinking level and survey them in order to find a new method for enhancing programming skill. In addition, we analyzed the causes for the difference in how the abstract thinking level applies when the students understand various structures of computer programs. From the results, we can propose a computer programming education method that enhances students' merits and compensates their drawbacks in the near future.

The purpose of using CBD in the object-oriented modeling is to improve the software capability by reducing iterative time and space complexity. Despites many achievements of CBD, it is needed to study about design patterns and it's standardization for the increment of CBD design reusability. However, it is rather possible that impetuous constructing meta-pattern languages and pattern repositories make adapting patterns to software development more complicate and difficult. By applying GoF design patterns to the design of the TMDL(Total Maximum Daily Load) environmental software discipline, this study suggests a method which specifies Pattern names at class names for retrieving, exploring the adapted patterns on the stage of software design without meta-pattern language which is a redundant abstraction, nor additional pattern repositories. Thus, this study can contribute on the reducing iterations and repetitions that are frequently occurred in the process of the environmental software developments.
