We examined the temperature-dependent structural and magnetic properties of HgI2 in the temperature range of 300~400 K. HgI2 is a diamagnetic material and can be used for X-ray or γ-ray detectors. DCmagnetization measurements on HgI2 showed that there is a small but distinguishable change in its diamagnetic properties near 375 K. The magnetic property change is not expected because Hg and I are known as nonmagnetic elements. X-ray diffraction (XRD) measurements revealed a structural transition in the temperature of 350~400 K. Temperature-dependent x-ray absorption fine structure (XAFS) demonstrated that the chemical valence states of both Hg and I did not changed in the temperature range of 300~400 K. However, XAFS revealed that the bond-length disorder was slightly increased in the temperature range, particularly, near Hg atoms. The structural changes of HgI2 are likely related to its diamagnetic property change. We will discuss the relation between the diamagnetic properties and local structural properties of HgI2 in detail.

Purpose: The aim of our study was to evaluate the therapeutic effects of walking and turning plus treadmill training on the functional balance and walking ability of individuals with Parkinson's disease (PD). Methods: Twenty-four participants with Stage 1 to 3 ($2.13{\pm}0.64$) PD based on the Hoehn and Yahr scale were randomly allocated to the experimental group (EG) and control group (CG), with 12 participants in each group. The measured outcomes included the motor subscale of the unified Parkinson's disease rating scale (UPDRS-M), the Berg balance scale (BBS), the Timed Up and Go (TUG) test, the 10-meter walk test (10MWT), and the 6-minute walk test (6MWT). Results: Pre-to-post intervention improvements were noted for all the outcome measures for both groups (p < 0.05). Post intervention, there was a significant improvement in the EG compared to the CG for the following measured outcomes (p < 0.05): UPDRS-M (p = 0.021; 95% CI, 0.081-6.519), BBS (p = 0.042; 95% CI, 1.375-4.541), TUG (p = 0.034; 95% CI, -3.315--0.143), 10MWT (p = 0.011; 95% CI, -2.032--0.289), and 6MWT (p = 0.002; 95% CI, 24.39-91.273). Conclusion: Our study suggests that walking and turning plus treadmill training improves balance and walking compared to treadmill training only in patients with PD.

This study aimed to visually compare the implementation of digital virtual fabrics for stretch fabrics mainly used in clothing that closely touch the body, using CLO. A digital fabric was used in CLO after measuring the weight, thickness, bending, and tensile force of five adhering clothing fabrics using a CLO fabric kit. The visual similarity of draftability was compared by measuring the area of the bending angle and the shape of the wrinkles of the real and digital fabric. A comparison of the bending angles showed that Fabric A was -0.75° and Fabric D was -2.5°, showing slightly lower drape properties than the real fabric. Meanwhile, Fabric B was 2.75°, Fabric C was 2.13°, and Fabric E was 1.375°, showing slightly higher drape properties in the vertical direction than the real fabric. Comparing the widths of the drape shapes, Fabric A was 0.77%, Fabric B was 1.27%, Fabric C was 0.06%, and Fabric E was 1.48%, which showed a slight difference. Fabric D showed a difference of 3.17% and was implemented where the digital fabric spread a little wider. As a result, the stretch fabric was visually expressed similarly to the real fabric as a whole in CLO. For 3D virtual clothing technology to be used widely in the close clothing industry in the future, more research on real clothing is needed.

The results of this study are briefly summarized as follows: First, the answer wanting professional hand care was more than half (53.3%). It turned out that customers prefer basic manicure such as hand massage(43.4%) and cuticle removal(31.1%) than nail art(15.2%) and nail improvement care(10.3%) in professional nail care. The basic manicure are in remarkably high demand which are often received with nail art and nail improvement care. There were more interests in nail services and better hand health condition in the 30's group than 40's. Also significantly higher in a unmarried group than married. this results show that professional hand care is highly related to a good condition of hands and additionally life satisfaction of customers. We were convinced of the direction of inner beauty and satisfaction beyond the visible. At the same time, exploring specific methods to internally satisfy customers remains to be a challenge.

We have developed a highly efficient boiler system using the 2,600cc Diesel engine. In this system, the co-generation concept is utilized in that the electric power is produced by the generator connected to the engine, and waste heat is recovered from both the exhaust gases and the engine itself by the shell-and-tube heat exchangers. The heat exchanger connected to the engine outlet is specially designed such that it not only recovers waste heat effectively from the exhaust gases, but significantly reduces an engine noise. It is found that the total efficiency(thermal efficiency plus electric power generation efficiency) of this system reaches maximum 96.3％ which is about 15％ higher than the typical Diesel engine boiler system currently being used worldwide.

Pulsed Er:YAG and $CO_2$ lasers induced temperature rise of tissue are studied using axisymmetric, two-dimensional, and transient Pennes' bio-heat equation or the implications of skin resurfacing. Model results indicate that Er:YAG laser induced temperature has much higher but more shallow distribution in tissue than that of the $CO_2$ laser because of its higher absorption coefficient. The increase of repetition rate does not affect the temperature rise too much because these laser modalities have much shorter heat diffusion time than the temporal length of each off-pulse. This model works as a tool to understand the photothermal effect in the laser-tissue interaction.
