  • General-purpose classification scheme encompasses all subject areas, While the whole classification scheme is constructed by library studies experts, structure and preparation of each specific subject area's classification should be referenced to that specific subject. In order for the whole system to be practical and useful classification scheme, not just a simple collection of each subject area's scheme, it is necessary to set the rule for properly distributing the amount of classification items, and the collections assigned to these items. The rule to set the distribution of items based on the amount of document collections is called 'literary warrant'. This study examines actual status of assignment of each classification items to information resources, as a result of application of Korean Decimal Classification, and then suggests a way to improve these practices.

  • In this study, we analyzed elementary school teachers' perception and method of establishing a new subject according to their computing competency. First, we developed a survey on the need to establish a new elementary school informatics. We also collected data from 166 elementary school teachers. As a result of the analysis, opinions differed on the establishment of information subjects depending on teachers' computing competencies. Teachers also showed differences in the characteristics of their subjects, number of class hours, and methods of organizing classes. As the results, we found that in order to establish a new information subject, a plan must be prepared to raise awareness and the need for informatics subjects among teachers who have low computing compency or no major in computer-related fields. We hope that many elementary school teachers will recognize the necessity and importance of establishing a new information subject.

  • This thesis analyzes the behavior of Korean senior officers corroboratively. The subject of research is a group of senior officers who were graduated from the Korea Military Academies of three armed forces, promoted to colonel at their first screen, and served for the duration of active duty on 18-22 years. The study reviews a correlation between the academic record and military promotion, and also between it and the duration of active service. Tri-dimensional leader effectiveness model, which P. Horsey and K.H. Blanchard developed to analyze LEAD (lead effectiveness and adaptability description), is used to evaluate the basic leader behavior styles.

  • Cardiovascular and respiratory responses of fish exposed to environmental hypoxia have on the subject of a number of investigations. Although relatively few species have been examined, generalized responses to ambient hypoxia include an elevation of blood pressure, increased systemic vascular resistance and bradycardia (Fritsche and Nilsson, 1990; Bushnell and Brill, 1991). The degree of bradycardia experienced by fish during hypoxia is highly variable and may depend upon the severity of the hypoxia and the rapidity with which it is imposed. (omitted)

  • Since the 1960s of industrialization families in Korea have experienced radical changes. One salient aspect of this is the increasing rate of divorces and subsequent remarriages. But few researches were done on the subject of remarriage and stepfamily research 3) The research sphere related to remarriage. This paper closes with suggestions regarding the future study on remarriage and stepfamily in Korea.

  • Toughening of epoxy resins for improvement of crack resistance has been the subject of intense research interest during the last two decades. Epoxy resins are successfully toughened by blending with a suitable liquid rubber, which initially remains miscible with epoxy and undergoes a phase separation in the course of curing that leads to the formation of a two-phase microstructure, or by directly blending preformed rubbery particle. Unlike the situation for thermoplastics, physical blending is not successful for toughening epoxy resins. Recent advances in the development of various functionalized liquid rubber-based toughening agents and core-shell particles are discussed critically in this review.

  • This research examined intuitive knowledge of 6th grade students in Israel prior to the formal learning of percentages in school. In other words. the research investigated knowledge of basic concepts and familiarity with the usage of percentages in daily life. Results have shown that students are familiar with the concept of percentages and thai some students are able to handle simple problems composed of common percentages (50% and 25%). However, it was also found that many students had misconceptions that should be taken into account while the subject has been taught.

  • Objective : The purpose of this study is to explore the effectiveness of a perceptual motor program in promoting visual motor and motor control outcomes in a child with Attention-Deficit/Hyperactivity Disorder (ADHD) who is enrolled in an elementary school. Methods : The subject is 8-year-old boy who was diagnosed with ADHD but did not receive medication. Research design is a single-subject A-B-A(follow-up). Baseline and follow-up phase were 3 sessions and intervention phase were 8 sessions. After performing 40 minutes of free play on the baseline A and follow-up A, we used the copying subtest of the Korean Development Test of Visual Perception 2 (K-DTVP-2) for evaluating visual motor integration skill and the rope jumping subtest for motor skill. After providing the perceptual motor activity in intervention phase B, copying and ropejumping were performed. Results : The standard scores of the Copying for measuring visual motor integration skill were poor at an average of 4.7 points at baseline phase A, but maintained an average of 9.6 points at intervention phase B and an below average of 7.7 points at the follow-up phase A. In the Rope jumping for the motor skill, it was increased by 4.3 times in the baseline phase A and 5.9 times in the intervention phase B, but slightly decreased by 5 times in the follow-up phase A. Conclusion : This study suggests that perceptual motor program has a positive effect on visual motor and motor function of ADHD children.

  • Objective : The purpose of the present study is to investigate the effects of Ayres Sensory Integration (ASI®) with play-centered oral defensiveness reduction activities on the oral sensitivity of a child with oral defensiveness. Methods : The subject was a three-and-a-half year-old boy with a developmental delay. The study was performed from August to September, 2018. The research design used in this study is the design for single-subject research. The experimental period was divided into three phases: three sessions for the initial baseline phase (A), 15 sessions for the treatment phase (B), and three sessions for the final baseline phase (A'). Ayres Sensory Integration (ASI®) with active oral play was conducted in the treatment phase. The Measuring Oral Sensitivity in Practice was used to test changes in the oral sensitivity level. The Korean Children's Eating Behavior Inventory and Food Checklist were used to assess the difference in functions related to oral sensitivity before and after the intervention. Results : In comparison with the baseline phase, the Measuring Oral Sensitivity in Practice and Korean Children's Eating Behavior Inventory were improved during the treatment phase, but the Food Intake checklist score was not changed after the treatment phase. Conclusion : The use of Ayres Sensory Integration (ASI®) with active oral play produced positive results and reduced the child's oral sensitivity and eating problems.
