This study presents "The Subject List for Developmental Bibliotherapy", for the purpose of offering selfdevelopment information to university students to assist them in identifying problems, and solving them while strengthening their egos. Theories relating to developmental psychology of young adult, results of analysing of student survey and successful examples of bibliotherapy subject lists from other universities have been applied for classifying of subject of this study. The four classes, are physical/mental development, social/emotional development, cognitive development and career development, have been classified into sub-classes and divisions in this study. With fixed career goals based on documents of developmental bibliotherapy, students can manage a more effective university education as early as their freshman year.

This study was conducted to attain an in-depth understanding of students' mathematical representations and to present the educational implications for teaching them. Twelve mathematical tasks were developed according to the six types of problems. A task performance was executed to 151 third graders from four classes in DaeJeon and GyeongGi. We analyzed the types and forms of representations generated by them. Then, qualitative case studies were conducted on two small-groups of five from two classes in GyeongGi. We analyzed how individuals' representations became elaborated into group representation and what patterns emerged during the collaborative small-group learning. From the results, most students used more than one representation in solving a problem, but they were not fluent enough to link them to successful problem solving or to transfer correctly among them. Students refined their representations into more meaningful group representation through peer interaction, self-reflection, etc.. Teachers need to give students opportunities to think through, and choose from, various representations in problem solving. We also need the in-depth understanding and great insights into students' representations for teaching.

In order to investigate the differences of nutrient intakes by the economic status and different age groups and to identify the nutritional risk group and its specific nutrition problem, 2001 Korean National Health and Nutrition Survey were analyzed. The subject's numbers of 9,391 were classified into four classes such as low (14.2%), medium (37.2%), high (26.0%), and high above (22.6%) on the basis of the family monthly income and the 2001 Korean minimum cost of living according to the family size. Mean intakes of energy and all nutrients assessed by the RDAs, lipid-energy %, and MAR were increased as the economic status were going up. Na intake expressed per 1,000kcal was in reverse. Nearly a half(45.5%) of the low-income people seemed to take nutritionally inadequate diet in consideration with MAR values. Deficiencies of iron and even energy in the toddlers (1 to 2 years) of low-income class were of great concern. Adolescent age group has been observed that their calcium and iron intakes, and possibly energy, were appeared to be the most deficient among all the age groups regardless of the economic status. For the elderly in all the economic status except high-above class, calcium, vitamin A, and riboflavin were commonly deficient nutrients. Calcium deficiency was appeared throughout nearly all the ages except toddlers and all the economic classes. Even in the high-above class 57.3% took insufficient amount of calcium.

Asteroid taxonomy dates back to the mid-1970's and is based mostly on broadband photometric and spectroscopic observations in the visible wavelength. Different taxonomic classes have long been characterized by spectral slope shortward of 0.75 microns and the absorption band in 1 micron, the principal components. In this way, taxonomic classes are grouped and divided into four broad complexes; silicates (S), carbonaceous (C), featureless (X), Vestoids (V), and the end-members that do not fit well within the S, C, X and V complexes. The past decade witnessed an explosion of data due to the advent of large-scale asteroid surveys such as SDSS. The classification scheme has recently been expanded with the analysis of the SDSS 4th Moving Object Catalog (MOC 4) data. However, the boundaries of each complex and subclass are rather ambiguously defined by hand. Furthermore, there are only few studies on asteroid taxonomy using Johnson-Cousins filters, and those were conducted on a small number of objects, with significant uncertainties. In this paper, we present our preliminary results for a new taxonomic classification of asteroids using SMASS, Bus and DeMeo (2014) and the SDSS MOC 4 datasets. This classification scheme is simply represented by a triplet of photometric colors, either in SDSS or in Johnson-Cousins photometric systems.

Purpose: The aim of this study was to explain the burnout among health teachers in elementary schools with large class sizes, and to explore the nature and meaning of those experiences. Methods: This study used the four steps of Giorgi's descriptive phenomenology. Data were collected through in-depth interviews regarding the experiences of burnout of 9 participants, which were recorded, transcribed, and analyzed. Results: The participants' experiences of teaching large classes were categorized into 4 themes and 9 domains. The themes were "difficult and lethargic," "gradual deterioration conditions," "losing work-life balance," and "enduring for a short time and leaving." Conclusion: Burnout not only affected the teachers at work but also had a negative impact on the teachers' personal and family lives outside of school. This study found that the current teacher assignment criteria were the strongest factors influencing burnout, which contribute to physical exhaustion. Health teachers are assigned based on different criteria that do not consider the number of students. Another factor contributing to burnout among health teachers is a work environment conducive to with emotional exhaustion. Health teachers and content teachers are not sufficiently knowledgeable regarding the specifics of each other's work.

The present study examined vocabulary usage in elementary English classrooms in Japan using elementary school corpus. The authors used three wordlists to benchmark the lexical items for four classes in the corpus: the CEFR-J, the General Service List (GSL), and Academic Word List (AWL). The percentage of vocabulary usage belonging to the Level A1 in the CEFR-J was below 15% (Class A: 12.1%, Class B: 12.6%, Class C: 8.9%, and Class D: 13.6%) with no statistical difference between levels. The mean ratio of Level A2 vocabulary items was below 10%, and all classes showed less than 1% of vocabulary usage for the Levels B1 and B2. Over 70% of all vocabulary items in the corpus belonged to the most frequent 1,000-word band (level 1) of the GSL, while the next most frequent word band (level 2 of the GSL and AWL) accounted for less than 10%. The results suggest that elementary school English teachers should use more vocabulary items in the CEFR-J Level A1. The findings demonstrate that elementary school teachers are less likely to expose their pupils to grammatically well-structured sentences with an abundance of lexical items since the teachers repeatedly use the same lexemes in each class.

This research aimed to investigate whether Korean education programs for secondary science teachers reflect constructivist perspectives. To identify how to introduce the idea of constructivism and STS into the courses of the current Korean education programs for secondary science teachers, two programs were selected: the Qualifying In-service Program held in Seoul and the pre-service programs established in the four departments of science education of the Korean National University of Education in Chungbuk. The course guidebooks, syllabi, and text materials prepared for implementation of the courses were collected and analyzed. E-mail correspondence with the program instructors who had conveyed both ideas to the trainees provided us more precise information about the characteristics of the classes, such as the total time provided the ideas and the teaching strategies used to implement the classes. The results indicated that the pre-service programs included the ideas of constructivism and STS more than did the Qualifying In-service Program. It is necessary that the courses included in the Korean in-service program, in particular the Qualifying In-service Program for secondary science teachers, have to be more focused on the constructivist perspectives.

The purpose of this study was to investigate beginning elementary teachers' characteristics and improvement of their teaching skills in science class. The methodology of this study was a qualitative approach that included interviews, classroom observations, and teaching materials. In urban area, low beginning elementary teacher were selected. Four beginning elementary teachers were observed and recorded with VCR in their classroom at seven-times. The results showed that the beginning elementary teachers did not improve in their teaching skills in science teaching, and their characteristics of teaching skills in science were summarized as following; 1) their teaching methods were not inquiry-based science teaching, but explaining-based science teaching, 2) their main aims of the science teaching were focused on the science knowledges, 3) there were little students' science processes involved in their classes, 4) they focused on using textbook as teaching materials, 5) there were little waiting times after their questioning, and they usually used closed-questions rather than open-ended questions.
