Purpose: This study examined the application of electric stimulation to the auricle acupoint (frequency 2 Hz, stimulation level: noxious) with 30 elderly people over 65 years that received treatment in a rural hospital to determine the influence of pain, gait and balance in the aged with knee joint disease. Methods: The subjects were divided into three groups; the degenerative joint diseases (DJD) group (1 male, 9 females), the total knee replacement (TKR) group (1 male, 9 females) and the control group (1 male, 9 females). Auricualr electrical stimulation (AES) was applied with low frequency, high intensity transcutaneous electrical nerve stimulation for 10 seconds per each point. Results: 1. For the change of pain according to AES, there was interaction in the resting period (p<0.001) and gait (p<0.001) and pain of the DJD group and TKR group was decreased. 2. The range of motion (ROM) of the knee joint showed a significant difference in interaction for each group of elderly people (p<0.001) and the ROM for the DJD group and TKR group of elderly people was increased. 3. In the analysis of gait speed changes, there was a significant difference in interaction for each group of elderly people (p<0.001) and for gait speed in the DJD group and TKR group of elderly people. 4. It was found in the change of static balance that there was a significant difference in interaction for each group of elderly people (p<0.01) and balance capacity in the DJD group and TKR group of elderly people was increased. Conclusion: The aged with knee joint disease have pain, and a decreased function of gait and balance. AES was an excellent treatment for control of pain, and an excellent treatment to enhanced joint functions. AES was useful for improving gait and balance due to decreased pain.

Sertoli cells in the normal adult testis are nondividing cells, which are relatively inconspicuous on cross section of the seminiferous tubule and comprise about 10% to 15% of the tubular cellular elements. Ultrastructurally, Sertoli cells have characteristic nucleoli, plasma membrane, and cytoplasmic components. The plasma membrane has two types of intercellular junctions which are developed at puberty: junctions between adjacent Sertoli cells and Sertoli cell-germ ceil junction. However, the ultrastructural findings of Sertoli cells in human fetus is not fully elucidate yet. In the present study, human fetal testes ($14\sim27$ weeks) obtained from artificially induced abortions legally without gross malformation were studied using transmission electron microscopy to make clear the differentiation process of Sertoli cells in human. In human fetal testes from 14 weeks to 27 weeks, the cell junctions of Sertoli-germ cells and Sertoli-Sertoli cells are desmosome like structure and not tight junction or desmosome. The Overall intracytoplasmic organelles of Sertoli cells are relatively sparse. The mitochondrias are relatively abundant but no developed cristae. And the rough endoplasmic reticuli are abundant and smooth endoplasmic reticuli are sparse. The amount of lipid droplets are regularly observed in human fetal Sertoli cells. No microfilaments or Charcot-Bottcher's crystalloids are present. From the results, Sertoli cells in human fetal testes are somewhat different ultrastructural findings with puberty or adult. However, to make clear the differentiation process of Sertoli cells in human, further study for 28 weeks to puberty is required.

The purpose of this study is to suggest a method to reduce the dose by Analyzing the dose area product (DAP) and image quality according to the change of tube current using NEMA Phantom. The spatial resolution and low contrast resolution were used as evaluation criteria in addition to signal to noise ratio (SNR) and contrast to noise ratio (CNR), which are important image quality parameters of intervention. Tube voltage was fixed at 80 kVp and the amount of tube current was changed to 20, 30, 40, and 50 mAs, and the dose area product and image quality were compared and analyzed. As a result, the dose area product increased from $1066mGycm^2$ to $6160mGycm^2$ to 6 times as the condition increased, while the spatial resolution and low contrast resolution were higher than 20 mAs and 30 mAs, Spatial resolution and low contrast resolution were observed below the evaluation criteria. In addition, the SNR and CNR increased up to 30 mAs, slightly increased at 40 mAs, but not significantly different from the previous one, and decreased at 50 mAs. As a result, the exposure dose significantly increased due to overexposure of the test conditions and the image quality deteriorated in all areas of spatial resolution, low contrast resolution, SNR and CNR.

The gait instability in the elderly has been associated with age-related deterioration in physical strength and reducing the potential for elderly falls requires regular exercise. In 2005, National Center for Injury Prevention and Control(NCIPC) reported that most elderly falls occur during activities in daily living(ADL). To better reveal biomechanic mechanisms underlying age-related degeneration in gait stability, and to enhance the assessment of falls risk, an accurate quantification of a person's balance maintenance during locomotion is needed. Instantaneous orientation of the line connecting COP and COM can characterize whole body position with respect to the supporting foot during gait and the angle between this line and the vertical line passing through the COP known as a good assessment to detect the elderly gait instability. Therefore the purpose of this study was to investigate a 6-month walking exercise effects in reducing elderly fall risk factors by using COP-COM inclination angles. Twenty-two community-dwelling elderly participated this study. The participants performed a walking exercise(3 times/week, 1 hour/visit) for 6 months. Laboratory kinematics during walking was assessed at months 0, 3 and 6. Significant increased in gait velocity was found among periods(p=.011, $1.25{\pm}.03$, $1.32{\pm}.03$, and $1.39{\pm}.04\;m/s$ in 0-, 3-, and 6-month, respectively). Also, significant differences in anterior and posteriror inclination angles were found among the periods(p<.05; posterior inclination angles: $12.8{\pm}2.2$, $11.0{\pm}2.9$, & $10.9{\pm}1.9$; anterior inclination angles: $13.7{\pm}1.7$, $14.6{\pm}3.2$, & $1.46{\pm}.21$ in 0month, 3month, & 6month, respectively). These findings provide evidence of significant reduced fall risk factors of community-living older adults associated with a systematic walking program.

Objectives: The objective of this study was to evaluate the generating characteristics of VOCs and the exposure effect to chemicals among laundry workers and to identify the current status of occupational safety and health through health check-ups. Methods: During the six-month period from April to September 2015, this study quantitatively measured seven VOCs in ten laundries and carried out health examinations on 35 workers. Results: Comparing the monitoring results for the ten laundries, they were classified into three groups by ventilation system, dry-cleaning and size of shop. The average concentration of toluene, chlorobenzene, xylene, ethylbenzene, benzene, styrene and TCE were 23.9, 15.6, 5.5, 2.8, 0.9, 0.3 and $1.3{\mu}g/m^3$, respectively. During dry-cleaning, VOC concentrations were 1.3-8.9 times higher than usual. On the other hand, at night the concentrations of toluene, chlorobenzene, xylene, ethylbenzene, benzene, styrene and TCE were 64.3, 41.5, 12.2, 6.3, 1.1, 1.2 and $6.6{\mu}g/m^3$, respectively. The health checkup results for the 35 workers showed that 13 workers were diagnosed as normal, while 22 workers were diagnosed as requiring continuous monitoring or re-checkup of liver and hematogenous functions. Conclusions: Although the results of exposure evaluation to VOCs did not exceed reference value and items had a low correlation with health checkup items, it is necessary to improve indoor air quality due to VOC volatilization from clothes.

Theosteoporosis, which is occurred after menopause, is a kind of metabolic bone disorder. It develops when the bone mass begins to decrease radically and its main symptoms are the bone fracture and the height-shortening. This thesis aims at what effects the Phlomis umbrosa will have for the prevention of the osteoporosis in the SD-rat that is caused by the ovariectomy. The 24 female white rats, after their ovaries are removed, were divided into the Normals, the Control group, Phlomis umbrosa Administrated group. After then, for 8 weeks, D.W to the normals and the control, and the Phlomis umbrosa(46 mg/100 g) to the Phlomis umbrosa group were given in the mouths of them. After 8 weeks the rats were sacrificed. And the weight, albumin, AST, ALT, total-cholesterol, triglyceride, P, Ca, T4, estradiol, the weight of the femur, the amount of tibia ash, the area of trabecular bone, the thickness of trabecular bone were measured. The serum analysis shows that the total cholesterol of the Phlomis umbrosa Administrated group reduced remarkably, compared to that of the control group. AST, ALT, ALP, T4 of Phlomis umbrosa group were decreased, but not in distinct measure. Estradiol of Phlomis umbrosa group increased substantially compared to that of the control group, but albumin, triglyceride, Phosphorous, calcium of the group showed the tendency to increase, but not so remarkably. The histological observation shows that the area and the thickness of (trabecular bone), the number of osteoclast of the Phlomis umbrosa groups increased significantly compared to those of the control group. Conclusions: The above experiment shows that Phlomis umbrosa has the prevention effect by supplying estradiol.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.
