This study analyzed the effect of wearing a vest with an attached electric fan. Korean men in their 20s were given test "fan vests" equipped with fans on the chest, stomach, upper back, or lower back to wear. Participants wore them in a climate chamber set to replicate a summer environment (30±3℃, 75±1%RH, 0.2 m/sec). Subjective sensations and surface temperatures were measured. The attached fan on the front of the vest lowered the temperature of the vest and the skin surface where the fan was positioned, regardless of whether the wearer engaged in exercise. However, a fan attached to the lower back of the vest was effective in lowering the lower back of the vest as well as the upper back, back of the arm, and back of the neck. In addition, subjective evaluations indicated that a vest with fans attached to the stomach and lower back provided a cool sensation. However, it was confirmed that the design of an auxiliary tool capable of dispersing the weight is necessary since the weight of the fans can interfere with the comfort of wearing the vest.

Objective : To identify the risk factors for postmenopausal osteoporosis in Korea Materials and methods : Bone mineral density (BMD) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry in 808 apparently normal postmenopausal Korean women. Questions about life style, demographic parameters, medical history and social habits etc. were asked on these women; 2ll women with normal bone mineral density, and 597 women with osteopenia or osteoporosis. Results 'Age of >50 years, low body mass index (BMI; <18.5 kg/m2), long duration of menopause(>10 years), and previous history of fracture were associated with increased prevalence of osteopenia or osteoporosis. Women without the outside activity also showed a higher frequency of low bone mass, Risk for osteopenia or osteoporosis was low in women with high BMI (>23 kg/m2) and women with job. The prevalence of low bone mass appeared to be independent of the following parameters: socioeconomic status, familial history, smoking, drinking, exercise, previous use of oral contraceptive, coffee or milk consumption, and degree of sunlight exposure. Conclusion 'Age, BMI, duration of menopause, previous history of fracture and degree of outside activity are the risk factors for postmenopausal osteoporosis in Korea.

Rehabilitation treatments after orthopedic surgery promote postoperative healing in humans. In veterinary medicine, there is increased interest in rehabilitation treatments because they are potentially beneficial to animals in the post-operation period. This study examined the effectiveness of rehabilitation treatment in dogs that underwent orthopedic surgeries, including femoral head & neck ostectomy (FHNO) and medial patellar luxation treatment (MPLT). The group that received the rehabilitation treatment after FHNO (1.88 weeks) showed a significantly shorter recovery length of 6.62 weeks compared to those that did not receive the treatment (8.50 weeks). The other group that received the rehabilitation treatment after MPLT (4.38 weeks) showed a significantly shorter recovery length of 5.01 weeks compared to those that did not receive the treatment (9.39 weeks). For the qualitative evaluation, the types and frequencies of rehabilitation treatments were monitored. The rehabilitation programs used frequently were heat therapy, laser therapy, passive range of motion, exercise therapy, and aquatic therapy. A standard rehabilitation program after hindlimb surgery was suggested based on the quantitative and qualitative investigation. The results add additional evidence that showed the beneficial effects of rehabilitation treatments in dogs.

We report two rare cases of extensive bilateral subcutaneous emphysema that occurred during ordinary dental procedures. An air-driven high-speed handpiece, routinely used in dental procedures may cause subcutaneous emphysema when high pressure air is introduced into the loose connective tissues below the dermal layer. The first case occurred with surgical extraction of the lower third molar. The air introduced into the fascial spaces near the surgical field spread to the contralateral spaces, as well as the neck and chest areas. The second case also showed extensive bilateral subcutaneous emphysema caused by the introduction of compressed air from the handpiece during crown preparation without any invasive procedure. Cases where the emphysema extends beyond the treatment site to involve the contralateral cervicofacial areas have been rarely reported. Predicting the occurrence of subcutaneous emphysema is difficult, so it is important to exercise caution during routine dental treatment. If significant bilateral cervicofacial swelling is suspected to be due to subcutaneous emphysema, prompt diagnosis with securing the patient's airway will be necessary.

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 ${\leq}$ T-score ${\leq}$ 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin $B_2$ (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

Objective: Computers and smartphones have become a necessity for modern people, and the use of these things in an inappropriate position has increased the number of people who complain about neck problems. The purpose of this study was to compare the changes of cervical angle, range of motion (ROM) and pain threshold according to the McKenzie stretching and dry cupping therapy. Design: Cross-over design. Methods: We included 12 male and 6 female college students in their twenties, and conducted a pre- and post-test to evaluate the changes of each variable after the application of the McKenzie stretching and dry cupping therapy. Results: Neither the cervical spine angle nor the turtle neck angle showed any change in both the McKenzie stretching and the dry cupping treatment. In the McKenzie stretching, the pain threshold decreased, and the ROM of the cervical spine increased in all directions but there was no significant difference. The pain threshold was increased in the dry cupping treatment, and the ROM of the cervical spine was significantly increased in all directions (p<0.05). Comparisons of the McKenzie stretching and cupping treatment showed that the cupping treatment produced significantly greater pain thresholds and improvements in ROM of the cervical spine than the McKenzie stretching technique (p<0.05). Conclusions: Cupping treatment is more effective in improving ROM of the cervical spine and pain thresholds than the McKenzie stretching technique. In the future, cupping treatment will be one of the treatment options for pain and ROM impairments of the cervical spine.

The purpose of this study was to investigate Bone Mineral Density(BMD) and affecting factors on BMD of college women in Seoul. The subjects were 47 healthy college women aged 18-25 years. Antrophometric and body fat measurements were performed by Bioelectrical Impedance Fatness Analyzer(Tanita TVF 202). Blood pressure and pulse frequency were measured. Dietary intakes and general living habits were examined through questionnaires and nutrient intakes were analyzed by Computer Aided Nutritional Analysis(CAN) program for professional. Serum total cholesterol, TG(triglyceride), HDL-cholesterol, total protein, albumin, GOT, calcium were measured by Spotchem(SP-4410). Serum osteocalcin and alkaline phosphatase(ALP) were measured to monitor bone formation. BMD of lumbar spine(L2-L4), right hip(neck, ward's triangle, trochanter) and right forearm were measured by Dual Energy X-ray Absorptiometry(DEXA). Muscle strength was measured by examining leg flexion strength(right and left), leg extension power(right and left), handgrip power(right and left) and back strength. All data were statistically analyzed by the SAS PC package program. BMD of college women was normal(by WHO, 1994). Their muscle strength was bad(by national fitness guidebook, 1995). Only a mall number of them exercised (32.6% of subjects). There was no significant difference among BMD, muscle strength and % body fat(p<0.05). There were significant differences between BMD and total cholesterol as well as TG and VLDL-cholesterol(p<0.05). Total cholesterol was associated with decreasing BMD of the right forearm(p<0.05). TG and VLDL-cholesterol are associated with increasing BMD of right hip ward's triangle(p<0.05). There were significant differences among BMD, ALP and serum total protein. ALP was associated with decreasing BMD of the right forearm(p<0.05). There were significant differences between BMD and Ca as well as between Na and K intakes (p<0.05). Intakes of Na and K were associated with decreasing BMD of the right forearm (UD)(p<0.05). There were significant differences between in BMD and pulse frequently and serum albumin (p<0.05). Serum albumin is associated with increasing BMD of L3-L4(p<0.05), right hip neck(p<0.05). %Body fat, TG, VLDL-C, Ca intake, pulse frequency and serum albumin were associated with increasing BMD(p<0.05). Intakes of Na and K, ALP, total cholesterol, total cholesterol, total protein and height are associated with decreasing BMD(p<0.05). Overall results indicate that Ca intake but to be moderate in protein and Na intakes in order to increase BMD. Body exercise was recommended to increase BMD as well.
