The purpose of this paper is to investigate if the instruction using GSP to 4th graders for them to explore 'rectangles and making them' have an influence of understanding and retention of the knowledge, generation of the knowledge which is not dealt with during experimental treatment, and if they can reason based on what they have learned about it and about what has not been learned. According to the result from the data gained, learners in the experiment group show that they can retain, generate, reason better than ones in the comparison group.

This study was carried out to investigate relationship between plasma $\delta$ - aminolevulinic acid (ALAP) and lead exposure indices in exposure to lead. The subjects were 218 male workers in 2 storage battery companies and 2 secondary smelting companies. Blood lead(PbB), blood zinc-protoporphyrin( ZPP), urinary $\delta$ - aminolevulinic acid (ALAU), hemoglobin(Hb), and hematocrit(Hct) were measured as lead exposure indices. The results were as follows, 1. The means of blood lead and blood ZPP concentration of subjects were $27.2{\pm}14.0{\mu}g/d{\ell}$ and $55.1{\pm}47.6{\mu}g/d{\ell}$, respectively. The means of plasma $\delta$ - ALA and urinary $\delta$ - ALA concentration were $18.9{\pm}25.1{\mu}g/d{\ell}$ and $2.1{\pm}4.6mg/{\ell}$, respectively. 2. The concentration of ALAP was $11.2{\mu}g/{\ell}$ for below $20{\mu}g/d{\ell}$ PbB, $12.8{\mu}g/{\ell}$ for from $21-40{\mu}g/d{\ell}$ PbB, and $51.2{\mu}g/{\ell}$ for over $40{\mu}g/d{\ell}$ PbB, respectively. 3. ALAP was significantly correlated with ALAU(r=0.829, p<0.01), ZPP(r=0.724, p<0.01) and PbB(r=0.552, p<0.01).

Geopolymers have many advantages over Portland cement, including energy efficiency, reduced greenhouse gas emissions, high strength at early age and improved thermal resistance. Alkali activated geopolymers made from waste materials such as fly ash or blast furnace slag are particularly advantageous because of their environmental sustainability and low cost. However, their durability and functionality remain subjects for further study. Geopolymer materials can be used in various applications such as fire and heat resistant fiber composites, sealants, concretes, ceramics, etc., depending on the chemical composition of the source materials and the activators. In this study, we investigated the thermal properties and microstructure of fly ash and blast furnace slag based geopolymers in order to develop eco-friendly construction materials with excellent energy efficiency, sound insulation properties and good heat resistance. With different curing times, specimens of various compositions were investigated in terms of compressive strength, X-ray diffraction, thermal property and microstructure. In addition, we investigated changes in X-ray diffraction and microstructure for geopolymers exposed to $1,000^{\circ}C$ heat.

The purpose of this study is to investigate the effects of mindfulness training with psychological techniques in a professional archery team in South Korea. First of all, it is conducted to find the changes in mindfulness through the KIMS during the mindfulness training, and to analyze the changes in both mindfulness and psychological technique factors. After ten times of meditation (1h-1h30m/1d), ACT and MAC based on the mindfulness training program, there were significant positive influences of psychological factors such as techniques, acceptance, concentration behavior and attention behavior on an intervention group compared to a control group, resulting in KIMS. Although there were no significant differences in confidence and teamwork in the intervention group after the psychological techniques, there were positive effects on willpower, goal setting , concentration, anxiety control and imagery statistically in the intervention group. In conclusion, mindfulness training has positive effects on the mindfulness in Korean archers. This training also has a positive influence on psychological technique factors such as attention, imagery, concentration and anxiety control. According to previous literatures, it is proved that there were positive effects on the psychological technique factors with the changes in mindfulness. Therefore, it is required to develop tools which can measure the mindfulness and to apply the correlation of mindfulness and psychological techniques to the field.
