  • Milling qualities and indigestible carbohydrate fractions (ICF) depending on harvesting time of Goami2 (G2), mutant of Ilpum (IP) rice, was examined. Fifty days after heading (DAH) maximized head rice milling quality (57.69%) and ICF content ($5.09{\pm}0.36\;g/100\;g$). ICF contents and physical properties of G2 and IP at 50 DAH were compared. ICF of G2 was three times higher than that of IP ($1.61{\pm}0.09\;g/100\;g$). Parboiling treatment increased ICF of G2 to $7.18{\pm}0.16\;g/100\;g$. G2 showed lower water absorption index, which could lower pasting properties, but higher water solubility index, implying it contains more soluble components. Texture properties of G2 were different from those of IP, showing higher hardness, and lower adhesiveness and cohesiveness. Positive correlation was observed between ICF and hardness, but reverse correlation between ICF and cohesiveness.

  • The purpose of this study is to collect basic data which are prerequisite for quantitative analysis of coal logging data. The study involves laboratory measurements of physical properties such as seismic velocities (P,S-waves), resitivity and density of domestic and imported foreign coals. The relationships between these properties were analyzed by using cross-plots. Correlation between the physical properties of coal and the results of chemical analysis (calorie, fixed carbon, ash, moisture, volatile matter and sulfur contents) was also studied to obtain ideas about coal quality analysis using logging data. Summarized results are as follows: 1. $V_P$ is exponentialy related to $V_S$. And the average value of $V_P$ is about l.8 times as large as $V_S$. 2. Since coal has very low density compared with surrounding sedimentary rocks, density logging is appeared to be the best method for identifying coal seams and evaluating their qualities. 3. For the case of domestic coals, the ash contents and calorie show a perfect inverse relationship. Since the density increases as increase of ash content with a well-defined functional form, the ash content of domestic coals can be estimated by density measurements. 4. Because of low ash content, low density and high resistivity, foreign coals and domestic lignites are easily distinguished from domestic coals.

  • In an effort to evaluate the qualities of the unused woods designed for art materials, Yellow pine, Pitch pine, Suwon poplar, Platanus and Cherry grown in Korea has been investigated in the study. Physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods were examined. Among the five species, Cherry wood showed the highest density in green, air-dried and oven-dried conditions. Hardness of Cherry wood was higher than those of Suwon poplar and Platanus. In softwoods, Pitch pine showed greater hardness than Yellow pine. Yellow pine and Platanus had the highest values of wood surface roughness. Abrasion value of cross, radial and tangential sections was the highest in Yellow pine and Suwon poplar. It has been concluded from the experiment that physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods can be used as an indicator of the suitability for woodcraft material.

  • Microbiological and sensory qualities of Musaengchae prepared with gamma-irradiated red pepper powder were investigated during storage at $4^{\circ}C$. Total aerobic bacteria in non-irradiated raw materials prior to Musangchae preparation were 6.71 log CFU/g in red pepper powder, 3.39 log CFU/g in radish, 2.21 log CFU/g in scallion, and 2.10 log CFU/g in garlic, respectively. Coliforms(2.15 log CFU/g) were detected only in red pepper powder, and not in Musangchae to which gamma-irradiated red pepper powder. None of pH, Hunter's color value, or sensory properties were significantly affected by addition of irradiated red pepper powder. These results suggest that addition of such powder, after irradiation with less then 10 kGy, could improve Musangchae microbiological safety without changing the sensory or physical qualities.

  • "Living in the present moment," a Buddhist concept, was applied in this research. This concept urges the patients to cling neither to the past nor the future as well as being mindful of their body, feelings, mind, and mental qualities. The purpose of the study was to develop a "living in the present moment" model and to evaluate the power of "living in the present moment" in terms of physical and mental results. The study used non-participatory action research with quasi-experimental research design that included 3 camps composed of 6 main activities. The percentages, SD, and paired t-test statistics were used to analyze and compare 17 purposively selected diabetic patients from Pak Thong Chai Hospital before and after they attended the 3 camps. The patients improved significantly in terms of waistline, body weight, body mass index (BMI) and blood pressure (SBP and DBP). The mean of fasting plasma glucose (FPG) level was also changed considerably. The results revealed that the treatment helped the patients to gain self-awareness and self-realization (Yonisomanasikara), as well as knowledge and increased support from friends (Kalyanamitta). They also let go of their attachment to their physical and mental oppressions. This helped the patients to relieve their daily pain, fatigue, insomnia, and diabetes-related complications. About 75% of all patients were able to achieve lifestyle modifications. Therefore, implementation of the model should be expanded and utilized in other diabetic centers. The model might also be expanded to pre-diabetes.

  • Conditions of paper manufacturing process should be changed depending on the end use and paper properties. Most of the case, mixed pulps with long softwood fibers and short hardwood fibers are used to achieve proper qualities of product with reasonable production cost. For specialty paper manufacture the wood pulp and cotton linter pulp are usually mixed together. The objectives of this study is to analyze physical, mechanical and fracture mechanical properties of paper depending on SwBKP, HwBKP and cotton linter pulp(CLP) mixing. When the mixing ratio of SwBKP was increased, strength properties, such as tensile, tear, and folding endurance, were also increased. When the mixing ratio of SwBKP and HwBKP was increased, stress concentration index was decreased and fracture toughness was increased.
