This study was to evaluate the change in characteristics of concentration of ozone after exposure to high energy radiation in linac room. Background ozone concentration of linac room was measured and compared to ozone concentration around linac room. Background ozone concentration of linac room was mean $17.4{\pm}7.9ppb$. It was 50% of the ozone concentration($36.8{\pm}22.3ppb$) around linac room(p<0.05). The concentration of ozone after exposure to high energy radiation in linac room was elevated to double of background ozone level, intensity after exposure. with exposure time concentration of ozone increased proportionally. It showed maximum level at 130~180seconds and slowed a tendency to saturate. It required more than 10 minutes for ozone concentration in linac room to drop to ozone concentration around linac room. The concentration of ozone after exposure to high energy radiation is high enough to cause specific physical symptoms, such as acute dyspnea or chest pain due to dry cough. Exposure to high concentration of ozone in sealed linac room can aggravate pulmonary disease, so special attention is needed.

The ZZimzilbang is a room where many women eagerly go due to the special meaning women give to it related to their health. It is a different type of sauna room which maintains low degree of temperature, consisting of an Ondol room(Korean under-floor heating system, hypocaust) built with mineral stone radiating ultrared rays. Even though many women mention that they utilize it for health, there is no precise evidence of the effects on their health. This ethnographic study sought to define the phenomenon from the perspective of the women who experienced the ZZimzilbang. A convenience sample of 27 women was interviewed during a 15 month period from December 1995 to July 1997 in 12 ZZimzilbangs located in Seoul, Korea. The mean ages of the women 57.3 years ; seventeen women were housekeeper and only eight women had job : twenty women were married and three women among them were widows. The main reasons women patronize the place are : for mitigation and healing of physical signs and symptoms : composure ; safe lodging and boarding : control of outward appearance : control of health ; meeting and fellowship with friends : and custom. The outcomes of the utilization of the place were : mitigation of physical signs and symptoms : psychological tranquility : cosmetic and diet ; good use of spare time : and utilization of services provided there. Most women who visited ZZimzilbang for relief of physical signs and symptoms strongly mentioned a correlation to inadequate Sanhujori, the traditional postpartal and postabortal care for woman. Some of specific kinds of services provided in that place were alternative therapy such as acupuncture, negative cupping, finger-pressure, mugwort steam and various kinds of massage including massage of blood vessels that are influenced by Oriental medicine ; health education of breathing such as abdominal breathing or Danjeon(단전호흡) : and selling of many things including health foods, drugs for osteoporosis, and eutrophics. This study suggests that professional caregivers should further study this phenomenon for the development of adequate care of women with a resulting important in their quality of life.

We developed and evaluated an algorithm to calculate the target radiation dose in cancer patients by measuring the transmitted dose during 3D conformal radiation treatment (3D-CRT) treatment. The patient target doses were calculated from the transit dose, which was measured using a glass dosimeter positioned 150 cm from the source. The accuracy of the transit dose algorithm was evaluated using a solid water phantom for five patient treatment plans. We performed transit dose-based patient dose verification during the actual treatment of 34 patients who underwent 3D-CRT. These included 17 patients with breast cancer, 11 with pelvic cancer, and 6 with other cancers. In the solid water phantom study, the difference between the transit dosimetry algorithm with the treatment planning system (TPS) and the measurement was $-0.10{\pm}1.93%$. In the clinical study, this difference was $0.94{\pm}4.13%$ for the patients with 17 breast cancers, $-0.11{\pm}3.50%$ for the eight with rectal cancer, $0.51{\pm}5.10%$ for the four with bone cancer, and $0.91{\pm}3.69%$ for the other five. These results suggest that transit-dosimetry-based in-room patient dose verification is a useful application for 3D-CRT. We expect that this technique will be widely applicable for patient safety in the treatment room through improvements in the transit dosimetry algorithm for complicated treatment techniques (including intensity modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT).

Purpose: This case report examines the influence of proprioceptive neuromuscular facilitation (PNF) combined with a dynamic neuromuscular stabilization approach on balance in patients with cerebellar atrophy. Methods: The target subject of this case report was a 34-year-old woman who was informed of the purpose of this research and voluntarily agreed to participate in it. The case report conformed to research ethics based on the Helsinki Declaration. The target subject was confirmed to have cerebellar atrophy from an unknown cause in 2009 and was diagnosed with slight ataxia. At that time, she could carry out daily activities without physical therapy. On May 19, 2015, she suffered both a subdural hemorrhage (SDH) and subarachnoid hemorrhage (SAH) in a traffic accident. She was urgently moved to the emergency room and managed by nonsurgical treatment, and then, the cerebellar atrophy and ataxia gradually deteriorated. To evaluate the patient's balance capacity before and after intervention, the trunk impairment scale (TIS), trunk impairment scale (OLST) during eye-closing/opening, timed up and go test (TUG), and visual analogue scale (VAS) were conducted. The PNF intervention program was executed for 30 min, four times a week, for three weeks. Results: The TIS and OLST during eye-closing/opening were improved by as much as a point, by 8.15 s and 6.21 s, respectively, after applying the PNF program. TUG and VAS decreased by 1.33 s and 3 points, respectively, after intervention. According to the result, the OLST during eye-closing/opening and VAS improved remarkably in comparison with those before intervention. Conclusion: As the final result of the case report, PNF intervention combined with DNSA more effectively improved the static balance capacity, such as the OLST during eye-closing/opening and VAS, compared to the dynamic balance capacity. In addition, the intervention duration and period of the exercise program are recommended to be more than 1 h a day for four weeks considering the learning ability of a patient with cerebellar atrophy.

Purpose: This study was designed to help preparing the evidence-based data for the manual of heat applications by finding the differences of superficial and core temperatures after applying dry and moist heats on shoulder and thigh. Methods: Moist and dry heats were alternately applied on the 33 subjects a day apart from May 15, 2010 through June 9, 2010. The experiment was conducted with $23^{\circ}C$ to $25^{\circ}C$ room temperature and 50% to 66% of moisture from 2 to 6 p.m. After heat was applied on the shoulder of the subjects wearing shorts and gowns for 30 minutes, their superficial and core temperatures were measured. The same method was used on the thigh after two hours. Results: Both superficial and core temperatures on the shoulder and thigh increased significantly after heat therapy. There was no significant difference between the temperatures before and after intervention according to applying methods and regions. Conclusion: This study provides a theoretical basis that a dry heat is a convenient nursing intervention for hypothermic patients.

Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus (T2DM). The our study evaluated the beneficial effect of diet supplementation with Lentinus edodes on hyperglycemia and lipid metabolism in normal and type 2 diabetic rats. The animals were divided into 4 groups: group I(control) rats were fed standard diet (12% of calories as fat); group II (T2DM) rats were fed HFD (40% of calories as fat) for 2 weeks and then injected with STZ (50 mg/kg); group III and group IV rats were continually fed a diet containing 1% and 10% Lentinus edodes for 4 weeks after T2DM induction, respectively. After 4 weeks we determined biochemical parameters such as glucose, insulin concentration, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and glycosylated hemoglobin (HbA1c) concentration were also measured. There was a significant reduction in serum TC and TG in the Lentinus edodes supplement groups. The Lentinus edodes diet supplementation were found to have a potent lipid metabolism improvement as well as LDL concentration decreased and HDL concentration was increased. Concentrations of blood glucose and HbA1c in the experimental groups II were significantly decreased after 4 weeks compared with the control group. The Lentinus edodes diet supplementation is useful in regulating the glucose level, improves the insulin, HbA1c, serum lipid metabolism in experimental diabetic rats. We suggest that Lentinus edodes supplementation may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.
