This study was conducted to develop a forest education program through middle school curriculum linkage. We used the ADDIE model, comprising the five phases of Analysis, Design, Development, Implementation and Evaluation, to secure the objectivity of the program. In the Analysis phase, middle school textbooks were analyzed while considering middle school students' needs for curriculum linkage and the developmental stages of adolescents. The Design phase focused on promoting an understanding of curriculum subjects based on what was reviewed in the Analysis phase and concretized and organized a program that can be implemented in the forest, with a focus on science and physical education, based on the results of middle school students' needs. We also established the objectives and goals of curriculum linkage forest education, established the concept of the program, and selected the educational contents, teaching-learning methods, and evaluation methods. In the Development phase, we developed a 2-night, 3-day program linkage with the middle school curriculum and created a manual for instructors and a workbook for students. In the Implementation phase, we revised and supplemented the program through the first test operation with 24 students in their second year of middle school, after which, we carried out a six-session program for the 2-night, 3-day as the second test operation with 17 students in their second year of middle school. In the Evaluation phase, the program was evaluated by the students who participated in the second test operation using questionnaires on satisfaction and curriculum linkage understanding as well as rating scales for attitudes toward forests and environmental sensitivity. The results showed that middle school students showed positive significance in satisfaction and understanding of the middle school curriculum as well as attitudes toward forests and environmental sensitivity through the forest education program.

The purpose of this study is to develop a program which aims at providing a better understanding of parenthood, establishing a desirable value of being a parent and preparing for being a good father positively affecting children, and determine effects of the program on unmarried men who are in the so-called stage of 'not belonged youth'. The program consisted of 5 sessions titled 'My father, 'I will be a father, too', 'Being a good father I', 'Being a good father II' and 'I will be a respectable father'. 7 unmarried men surveyed here were asked to participate in the program held at B church located in Busan from Oct. 3 to Nov. 7, 2004, with 1 session a week and 120 minutes per session based. Before and after the program, tests were carried out with the father acceptance-rejection scale and the scale of confidence in father's role'. For each of the sessions, a process evaluation was performed. Results of the study can be summarized as follows. First, the pre- and post-tests with the father acceptance-rejection scale showed some changed recognition that father's attitude of child raising would be more acceptable and unrejectable. This indicates that the program made some achievements in relation to understanding and reestablishing relations with father. Second, significant differences were found in confidence in father's role between before and after the program. Especially, anxiety about father's role as a sub-area of such confidence was most considerably reduced. In conclusion, such objectives of the program as removing vague anxiety about father's role, establishing a desirable view of fatherhood and improving confidence about being a father proved to be achievable through getting skills of child understanding with the concept of developmental perspective and narrative therapy based.

분산 이동 실시간 시스템을 개발하기 위해 pi-Calculus, Mobile Ambients Calculus, Bigraph 등의 수많은 프로세스 대수가 존재한다. 하지만 시스템이 방대해지고 복잡해질수록 시스템을 구성하는 프로세스들의 통신과 이동 역시 방대해지고 복잡해지므로 프로세스 대수로 이를 이해하는데 어려움이 존재한다. 그러므로 방대하고 복잡한 시스템을 체계적으로 이해할 수 있는 방법이 필요하다. 본 논문에서는 방대하고 복잡한 시스템을 프로세스들의 통신과 이동의 순서화된 추상화 방법 즉, 계층적으로 구조화된 격자(Lattice)들의 형태인 프리즘(Prism)으로 다룬다. 이는 액티브 온톨로지(Active Ontology)에서 확장된 새로운 개념인 행위 온톨로지(Behavior Ontology)를 기반으로 한다. 프리즘은 시스템을 체계적으로 이해하기 위해 시스템을 계층적으로 구성된 행위적 속성을 지닌 격자들 관점에서 분석하는 것을 허용한다. 이러한 방법은 통신과 이동의 복잡함을 의미적이고 계층적으로 구성된 행위의 구조로 체계적으로 이해할 수 있게 한다.

Cleft lip is a common congenital facial deformity which might cause speech, hearing, appearance, and psychological disorder. For the purpose of appropriate management for the cleft lip patients according to their individual situations, reviews of the historical evolution for the cleft lip treatment were summarized. More than 15 English written articles with 4 related historical books were reviewed, and the chronology of the cleft lip management from ancient to recent twenty first century, via middle ages and Renaissance, were summarized. Multifactorial causes of cleft lip, before the modern understanding of embryological background of it, most management of cleft lip has been explained under the basis of religions and/or superstitions. As the anatomic and embryologic knowledges were known and revealed, various misconceptions were corrected continously, and the simple closure of the lip defect was also evoluted to the applications of plastic concept. Recently, cosmetic outcomes with functional results, such as speech, hearing, psychological status, have been considered importantly, under the multidiciplinary care system. For the better understanding of cleft lip management as a routine esthtetic and funtional reconstructive procedure, the various historical treatment trends were reviewed and summarized as time goes on. This review presentation will discuss the appropriate management for cleft lip patients.

The purpose of this study is find out the correlation of level of knowledge of pre-service elementary teacher with space perception ability on 'Earth and Space' of elementary science. During the second semester of 2013, for 15 weeks, the classes were conducted for 3 hours per week and we find out knowledge Understanding degree and select terms offered by 5th grade science courses 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section and measured space perception ability degree of pre-service elementary school teacher with a questionnaire. We analyzed the correlation of understanding level of knowledge in the field of astronomy of pre-service elementary school teacher with space perception ability. The results of the study are presented as follows. First, pre-service elementary school teacher showed a low level of knowledge understanding as it goes the upper grades about upper concept in 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section' of astronomy area of elementary science 'Earth and space sector'. The pre-service elementary school teachers needs to acquire knowledge of astronomy area in elementary school curriculum. Second, pre-service elementary school teacher showed that there are differences individually in 'finding solid body' of sub-element of space perception ability. This shows that 'finding solid body' factor is associated with space perception ability. Third, in the section of 'The earth and the Universe' for elementary education, 'Reflection' and 'Finding solid body' which are low-level components of space perception ability were verified that have a corelationship with general grades in the astronomy conception test.

The units about electricity in 5th and 6th science curriculum for elementary school was analyzed and the elementary students' understanding of related concepts was investigated. This study was to make connection between the research about alternative concepts and writing textbooks. It was found that students' response had following characteristics. They had strong belief that the + and - ends of battery should be connected. However this belief was not complete because students did not understand that the other circuit elements had to be connected properly. When the circuit involve more than one bulbs or batteries, they counted the number of batteries or bulbs only and paid little attention to the connection of them. In explaining circuits and the brightness of the bulbs in the circuits. students tried to explains the circuit using scientific terms but failed to used them properly. Although the concept of resistance was not dealt explicitly. student had reasonable qualitative understanding about resistance. According to response of students, several suggestions might be made for the curriculum. The structure and the circuit elements and the proper connection needs to be taught. Also more emphasis is necessary to pay attention to the connection in addition to the numbers of bulbs or batteries. Finally, it needs to be investigated carefully if it is better to introduce some qualitative model to explain the amount of current through bulb depending on the connection and the number of bulbs. It might also be better to introduce some terms, such as current and resistance with the model.
