Understanding limitation of simulation for Planetary Boundary Layer (PBL) height in mesoscale meteorological model is important for accurate meteorological variable and diffusion of air pollution. This study examined the accuracy for simulated PBL heights using two different PBL schemes (MYJ, YSU) in Weather Research and Forecasting (WRF) model during the radiosonde observation period. The simulated PBL height were verified using atmospheric sounding data obtained from radiosonde observations that were conducted during 5 months from August to December 2014 over the Gumi weir in Nakdong river. Four Dimensional Data Assimilation (FDDA) using radiosonde observation data were conducted to reduce error of PBL height in WRF model. The assessment result of PBL height showed that RMSE with YSU scheme were lower than that with MYJ scheme in the day and night time, respectively. Especially, the WRF model with YSU scheme produced lower PBL height than with the MYJ scheme during night time. The YSU scheme showed lower RMSE than the MYJ scheme on sunny, cloudy and rainy day, too. The experiment result of FDDA showed that PBL height error were reduced by FDDA and PBL height at the nudging coefficient of $3.0{\times}10^{-1}$ (YSU_FDDA_2) were similar to observation compared to the nudging coefficient of $3.0{\times}10^{-4}$ (YSU_FDDA_1).

This study explored the structural relationship between achievement goal orientation, learning motivation, and level of interest on the level of flow in distance PBL classes. A structural model was constructed through analysis of previous studies. Data for the verification of the structural model were collected from 59 students in the teaching courses. The study took PBL lessons remotely. After the PBL class was ended, flow, achievement goal orientation, learning motivation, and level of interest were measured. The collected data were analyzed using the structural equation model analysis method. As a result, the structural model proposed in this study was verified to be valid. It was verified that the level of interest mediated the influence of achievement goal orientation and learning motivation to influence commitment. Next, it was verified that the path through which the level of interest mediates the effect of achievement goal orientation has the greatest influence. Therefore, it is possible to suggest that the level of flow can be adjusted if the level of interest is adjusted in consideration of the achievement goal orientation of learners when operating distance PBL classes.

Backround : The paradigm of recent education has been shifting from existing style of professor-oriented, passive and rote teaching to learner-centered education. Rather than mere delivery of knowledge, today's idea of education uses various audiovisual media to let learners gain more problem-solving skills, judgment, cognitive thinking ability, and creativity to apply to real practice. Also, while current trends and change in policy ask for related industry to require practice-centered teaching learning model, Problem-Based Learning (PBL) is quite effective that it activates problem-solving skills as well as application of National Competency Standards (NCS). Purpose : The purpose of this study was to suggest a teaching learning model article as an approach to apply web-based PBL for patient & medical charge management practices. Discussion & Conclusion : This paper the cases on PBL and presents the teaching learning model on web-based PBL as an approach to applying web-based PBL, which fits Medical Information System Department that combines health-medical treatment and computer applications, to practical health administrative affairs.

In the 21st century, university education is changing from an objective knowledge and information to critical thinking and problem-solving ability. Moreover, university education should change rapidly towards a learner-centered educational environment because it has an educational goal to have college students experience authentic tasks they will be in charge of after graduation, and improves self-directed learning ability and cooperative learning ability. PBL is a pedagogical strategy for posing significant, contextualized, real world situations, and providing resources, guidance, and instruction to learners as they develop content knowledge and problem-solving skills. In problem based learning, the students collaborate to study the issues of a problem as they strive to create viable solution. For these advantages of PBL, the application of PBL in school has been enlarged. On the other hand, the application of PBL in engineering education has not been enlarged. To improve these instruction methods, the development or applications of new instructional methods will be needed. This study examined the PBL instructional design of a creative engineering design subject, which aims to foster talent. The PBL model developed in this study consists of Analysis, Design, Development, Implementation, and Evaluation. A plan of creative engineering design subject was developed based on PBL, and focused on the process of PBL. To determine the effects of this model, studies applying this instructional design to many lecturers should be implemented.

This study focuses on the comparison of PBL and GBS. PBL is a famous model that emphasizes diversity of students and self directed learning within the theory of constructivism. GBS has not been studied that extensively. GBS is most similar to PBL but this model has not been actively applied to school education. This study focuses on how to enhance students' interest in an educational environment that is encompassing a new and changing teach-learn paradigm and the development of new technology. Furthermore, PBL and GBS methods were compare actively applied to "Environmental Education" to make the students learn self-directed education through the transformation of one's environmental awareness. Specifically, the models were applied to the "Ecology and Environment" subject taught in general high schools and the degree of 'environmental literacy' were measured, From March to May of 2007, the PBL and GBS models were applied to 3rd grade students at D high school and the subject was 'Ecology and Environment'. The students were divided according to age into groups of $5{\sim}7$. The PBL group attempted to solve the given problems and the GBS group carried out their missions. In conclusion, after analyzing the 'environmental literacy' survey results by SPSS 12.0, just 'Knowledge of Ecology (KEOC)' and 'Locus of Control (LOC)' were slightly significant in PBL. This shows that PBL enhances the students' problem solving ability and thinking power. This is a result of the enhancement of students' problem-solving and thinking abilities through PBL. Students can learn many things because they completed their projects based on their experience and knowledge, both individually and interpersonally. We have to study how to apply PBL and GBS to the education field in spite of the many limited conditions. Therefore, this study looks at the application of PBL and GBS in environmental education and suggests specific strategies for educators who want to apply GBS and PBL and adapt them into their education curricula.
