Green Frame is a method for Rahmen structure construction composed of composite PC members. The composite PC members of Green Frame which are based on in-situ production can reduce the construction cost and are more likely to secure quality when compared to production in factories. Previous studies developed forms for in-situ production of Green Frame composite PC members and proposed algorithms to arrange them on site. However, it requires not only their arrangement, but also calculation of an accurate production period to produce the required PC members in a limited space and supply them in a timely manner. In particular, it is necessary to clearly define the properties of detailed processes for in-situ production of PC members and to calculate the time required for respective process. To do so, this study is a basic research on calculating the time for in-situ production using a linear scheduling method.

Objective: This purpose of this study was to analyze articles and research trends in children's free-choice activities in major domestic journals published from 1998 to 2017. Methods: Registered research papers in academic journals from 1998 to 2017 for the National Research Foundation of Korea were analyzed in terms of trends in their annual submission numbers, research subject, research type, research area. and research theme. Results: The quantity of the studies has more than doubled since 2010 but has decreased in recent years. Studies about free-choice activities for young children held the majority of research subjects while physical subjects such as literature, class, and education plans were in the minority. Furthermore, qualitative research, fusion qualitative, and survey were the most common research types while literature review studies were less common. Most research themes were studies about contemplation, actual conditions and perception, factor analysis, and programs of free-choice activities for young children. Conclusion/Implications: Considering the results of this study, further studies on free-choice activities for young children must be conducted.

This study investigates Korean language teachers' perception/beliefs and practices in written feedback. Two types of data were collected: (1) teachers' feedback on three compositions by elementary-level learners, and (2) a survey questionnaire. The result showed that teachers perceived written feedback to be important even though they had not enough opportunities to receive appropriate training. Lack of training brought about limited feedback in terms of both quantity and quality, and inconsistency between their beliefs and practice. This study closes with the needs for teacher training and further studies on teachers' feedback practices.

During the period of 1975-76, a survey was carried out to find out zinc indicators in the natural vegetation in Korea. The symptoms fo chlorosis were observed in flowering plants in the areas of zinc outcrop of Wolgok-A, Seokgok-9, and Sowolgok. Although 28 species were found to be chlorotic, the total quantity of chlorotic foliage observed was small. Reasons for chlorosis in the areas of zinc are deposits is considered as effects of zinc, lead, copper and calcium ions. Sedum sp. and Dianthus sinensis were confined to soil containing more than exchangeable zinc of 30 ppm and to accumulation in the plants contained at least 1,300-14,000 ppm of zinc. Therefore Sedum sp. and Dianthus sinensis might be used as zinc indicators in Korea.
