This study aimed to explore online learning profiles of in-service teachers in South Korea, focusing on video lecture and discussion activities. A total of 269 teachers took an online professional development course for 14 days, using an online learning platform from which web log data were collected. The data showed the frequency of participation and the initial participation time, which was closely related to procrastinating behaviors. A cluster analysis revealed three online learning profiles of in-service teachers: procrastinating (n=42), passive interaction (n=136), and active learning (n=91) clusters. The active learning cluster showed high-level participation in both video lecture and discussion activities from the beginning of the online course, whereas the procrastinating cluster was seldom engaged in learning activities for the first half of the learning period. The passive interaction cluster was actively engaged in watching video lectures from the beginning of the online course but passively participated in discussion activities. As a result, the active learning cluster outperformed the passive interaction cluster in learning achievements. The findings were discussed in regard to how to improve online learning environments through considering online learning profiles of in-service teachers.

The active treatment phase in preparation for bone marrow transplantation(BMT) of che- motherapy regimen and total body irradiation (TBI) containing regimen requires considerable teaching. There have been researches that are related to treatment onto BMT patients and to psychological change during BMT process. However, it was hard to find researches focused on learning needs of patients undergoing BMT. The purpose of this study was to provide the basic data for effective educational program about BMT by investigating the learning needs in patients undergoing BMT. The subjects consisted of 90 BMT patients have been admitted to the department of BMT at three university hospitals. Data were obtained from October 1998 to March 1999 and analyzed by SAS program for unpaired t-test, ANOVA, Duncan test. The results were as follows : 1. Learning needs related to demographic characteristics was identified as below. That of male was higher than that of female. That of under age 29, unmarried, religious and university graduated group was higher than that of opposite group but it didn't show significant difference. Learning needs of group of patients who were employed was significantly higher then that of unemployed patients. 2. According to types of diagnosis, learning needs of myelodysplastic syndrome(MDS) patients was the higher than that of others, but admission frequency was the least. Learning needs of unrelated matched BMT(UBMT) patients was higher than that of autologous BMT patients. However, it didn't show significant difference. With regard to learning needs according to process of BMT, learning needs of Pre- BMT period or Post-BMT period was significantly higher than that of BMT day. 3. Learning needs related to BMT was relatively high (total mean: 3.11 of 4.0). The order of the mean score of leaning needs was shown as follows : Restricted activities after discharge, Relapse symptom, Complications of BMT, Kinds of available drugs at home. Therefore the learning needs that is related to life after discharge and to relapse and complications after BMT was high. 4. Learning needs related to radiation therapy was high (total mean: 3.35 of 4.0). The learning needs in radiation therapy items was the Skin care of radiation therapy and Purpose of radiation therapy. 5. Learning needs related to graft versus host disease(GVHD) therapy was high (total mean: 3.55 of 4.0). The highest learning needs in GVHD therapy items was the Preventive method GVHD. less admission frequency and UBMT patients. It is necessary that education for BMT patients should be focused on life after discharge and on relapse and complications after BMT. Especially education for allogeneic BMT patients should be emphasized on GVHD. For all of these, it is necessary to develop systematic and concrete educational program.

Learning rate is generally applied to estimate an appropriate production labor cost. Learning effect is obtained from repetitive work during the production period under 3 assumptions ; homogeneous production, same producer, quantity measure in continuous unit. However, production breaks occur frequently in Korean defense industry environment because of budget constraint and annual requirements. In this case previous learning effect can not be applied due to learning loss. This paper proposed the application of learning rate when a production break occurs in Korea defense industry. To obtain a learning loss, we surveyed various learning loss factors for different production breaks(6, 12, 18 months) from 4 defense industry companies. Then, we estimate the first unit labor hours in re-production phase after production break using Anderlohr method and Retrograde method with the result of the survey. This work is the first attempt to show a method which defines and evaluates the learning loss factors in Korean defense industry environment.

The purpose of this study is to explore various factors during the career development period affecting the formation of the perspective on work of young workers after they graduated from high school, and to analyze the influence of each factor. The panel data of the Korean Education Longitudinal Study 2005 was used for the study. Specifically, the data on the 303 employees in the 7th year(2011) of their employment was used. First, perspective of young workers on work was affected by social self (self-awareness-related variables), educational background of their father(family background-related variables), and intrinsic and extrinsic learning motivation(learning motivation-related variables) formed during the career development period. However, extrinsic learning motivation had a passive and negative effect on motivation and giving value to work. Second, the variables related to self-awareness in the career development period and the variables related to the family background were found to have a causal relationship with the formation of young workers' perspective on work. This study is significant in that the learning motives formed during the career development period are found to be very meaningful and important variables for the formation of young workers' perspective on work.

The purpose of this study is to analyze the educational effect of learning mentoring conducted by EBS for elementary and middle school students, the changes in self-directed learning skills, emotional stability and learning effect were analyzed for 425 students who participated in the EBS learning mentoring. As a result, There was no statistically significant difference in the educational effect according to the mentoring service period, method, and frequency, and there was a statistically significant difference in self-directed learning ability according to the mentoring time. As a result of analyzing the effect of the perception of the mentor on the educational effect, the more positive the mentor and the more positive the mentor role, the higher the self-directed learning ability and emotional stability. As for the learning effect, mentoring satisfaction had the greatest influence on the learning effect of Korean, English, and mathematics. The mentor role was affecting the Korean language and mathematics. Therefore, in order to reduce the learning gap of underprivileged students in the distance learning situation, the EBS learning mentoring project should be continuously promoted, and the mentoring period and the number of students and teachers participating in mentoring should be significantly increased.

In information retrieval process through search engine, some users want to retrieve several documents that are corresponding with specific time period situation. For example, if user wants to search a document that contains the situation before 'Japanese invasions of Korea era', he may use the keyword 'Japanese invasions of Korea' by using searching query. Then, search engine gives all of documents about 'Japanese invasions of Korea' disregarding time period in order. It makes user to do an additional work. In addition, a large percentage of cases which is related to historical documents have different time period between generation date of a document and record time of contents. If time period in document contents can be extracted, it may facilitate effective information for retrieval and various applications. Consequently, we pursue a research extracting time period of Joseon era's historical documents by using historic literature for Joseon era in order to deduct the time period corresponding with document content in this paper. We define historical objects based on historic literature that was collected from web and confirm a possibility of extracting time period of web document by machine learning techniques. In addition to the machine learning techniques, we propose and apply the similarity filtering based on the comparison between the historical objects. Finally, we'll evaluate the result of temporal indexing accuracy and improvement.

This study investigates the change in two theoretical constructs, attitudes toward mathematics and mathematics self-efficacy, among college students involved in a learning community model. The case of this study was a developmental mathematics class offered at a historically black college located in the southeastern United States. Subjects included 31 students enrolled in an introductory mathematics course, some of whom participated in a learning community (treatment group). The participants completed mathematics attitudes and mathematics efficacy instruments twice: at the beginning of the semester and again at the end. Data was analyzed using descriptive statistics and a non-parametric statistic. The results showed that students' attitudes toward mathematics and mathematics self-efficacy are strongly correlated; the mathematical problem-solving efficacy changed significantly over time and it is significantly higher in the treatment group than in the control group; and the treatment group produced better outcomes. These findings indicate that a learning community model can increase students' mathematics self-efficacy beliefs. It is recommended that mathematics self-efficacy and attitudes toward mathematics be measured over an extended period of time when a learning community is implemented.

The influence of the social changes on the food and nutritional status of Korean during the late period of Joseon Kingdom (1800-1910) was analysed by using old literatures and the records of the Westerners visited Korea during the period. The late period of Joseon can be designated the most poor and miserable period in the history of Korea. The people suffered from the corrupted and incompetent government and social disturbances. The main driving forces to reforming the society at that time were 'Silhak' (Practical Learning), introduction of Catholic church and Donghak movement. The food related literatures written in this period in Korea described the life of upper classes (Yangban) and paid little attention to the life of the poor majority. This paper introduces the food availability and habits of Korean observed by the Westerners visited Korea at that time.
