Importance of the work-related musculoskeletal disorders (WMSDs) has been increasing in the hospital industry such as health care industry and financial industry. This study investigated in order to identify the factors like general, occupational and ergonomically characteristics of the subjects related to musculoskeletal disorders (MSDs) of physical therapists (PTs). Ergonomic tools of rapid upper limb assessment (RULA) were used for evaluation workload of the tasks. Prevalence of MSDs were 13 PTs (26.0%) for neck, 31 PTs (62.0%) for shoulder, 9 PTs (18.0%) for arm/elbow, 27 PTs (54.0%) for hand/wrist, 28 PTs (56.0%) for back, 14 PTs (28.0%) for leg/foot. The analysis of the rate of the pain intensity showed that 53.5% subjects experience moderate pain and 14.0% subjects experience severe pain. Factors which were general characteristics, for example, height, ergonomically characteristics such as 'Posture Score A' were related musculoskeletal subjective symptoms in logistic analysis (p<.05). Among physical therapists, action level of RULA were action level 2 (6.0%), action level 3 (52.0%), action level 4 (42.0%). Physical therapists were estimated one of the highest risk factor in this study. This study suggested that the need of preventive education and program for PTs (physical therapists). Comprehensive and systematic management plans should be established to include both ergonomic and sociopsychological aspects.

The purpose of this study was to assess the influence of patellar height on quadriceps muscles' electromyography (EMG) activity during a squat exercise in adults with patella baja. For the study, we recruited 15 volunteers who had patella baja on the right side. We measured the EMG activity of the right rectus femoris, vastus medialis oblique, and vastus lateralis muscles during squat exercises under two conditions, specifically with and without an infra-patellar strap. The infra-patellar strap was applied below the tested patella to elevate the patella to a normal height. A paired t-test was used to compare the effects of patella height on EMG activity of the quadriceps muscles. The EMG activity of the rectus femoris (RF), vastus medialis oblique (VMO), and vastus lateralis (VL) muscles were significantly decreased during the squat exercise with the infra-patellar strap compared to the same exercise without the infra-patellar strap (p<.05), while the VMO/VL ratio was not different significantly between two conditions (p>.05). The findings of this study suggest that an infra-patellar strap may benefit people with patellar baja, as changes in patellar height could improve the efficiency of the quadriceps muscles.

The purpose of this study was an determine whether elastic band on treadmill training might effect the chest expansion and pulmonary function of the 20's men. 40 subjects with experimental group(male: 20) and control group(male: 20) was participated in experiment. During four weeks, each group participated thirty minutes for three times per week. Subjects were assessed using pre-value and postvalue measurement chest length(chest length for resting, chest expansion) and pulmonary function(forced vital capacity, forced expiratory volume at one second, FEV1/FVC, peak expiratory flow, vital capacity, tidal volume, expiratory reserve volume, inspiratory reserve volume) by the CardioTouch 3000S(BIONET, USA). These findings suggest that experimental group can be used to improve chest expansion, pulmonary function than control group. In comparison of both groups, post-test was more improved in experimental group. In conclusion, experimental group helped improving function of pulmonary volume and respiratory muscle, and thus it indicates that the functions will be more improved through the continued respiratory exercise program.

The purpose of this study was to investigate the influence of the static pelvic inclination and declination in the static standing position on weight bearing rate and gait elements. Fourteen healthy adults in their twenties were participated. Two groups of healthy adults were allocated in this study: above and below the average of pelvic tilt. The correlation between the pelvic inclination, weight bearing rate and gait elements were measured. There was a statistical correlation between the pelvic tilt and step. Also, there was a statistical difference when we compared anterior declination with swing period and posterior declination with step. There was an asymmetric correlation between pelvic tilt and step. However, there was no statistical difference between the groups above and below the average of pelvic tilt. This result indicates that dipper pelvic inclination doesn't affect the asymmetry of step.

The rice weevil, Sitophilus oryzae, is the most serious storage pests worldwide of grocery shops, flour mills, and warehouses. The phototactic response of the rice weevil, S. oryzae, to light emitting diodes (LEDs) at five different wavelengths and various light intensities was tested within an LED-equipped Y-maze chamber, and compared with its response to a luring lamp, which is used in commercial traps. Various wavelengths in this study were UV (365 nm), blue (450 nm), green (520 nm), red (660 nm), and infrared (IR) (730 nm). Based on attraction rate (%), blue (84.3%) was the most attractive to S. oryzae, followed by green (74.3%), red (64.3%), UV (63.3%), and IR (48.7%). Moreover, blue and green wavelengths were 1.5 and 1.3 times more attractive than luring lamp (56.7%), whereas the UV wavelength was slightly less attractive to the weevils than luring lamp. These results suggested that blue and green wavelengths could be more useful than those currently used for monitoring and mass trapping of S. oryzae.

This study, adult men and women who live in Seoul with 100 people a dietary habit and eating traditional foods, traditional foods and recipes of the characteristics, educational experience and educational demand for traditional foods were investigated. Korean traditional food usually eaten in the usual (37.2%) and holidays(30.2 percent) to eat. Korean traditional food to eat because we did not have time reduction(38.4%), cooking methods is difficult(30.2%), mainly to select the menu when eating out, traditional food in Korea(58.1 percent). Korea traditional food with a traditional culture of Korea has developed dishes (45.3%), the food here is that we use most often(22.2%), Korea's unique attributes of traditional food deserves world-class(74.4%), nutritionally balanced, healthy foods (72.1%) and showed that recognition. Korean traditional food needs of education(62.8%) and the traditional excellence of the food(33.7%) and Korea traditional food culture and to develop succession (27.9%), traditional food for healthy eating awareness training was needed.

The aim of this study was to determine the immediate effects of single treatment of strain-counter strain (SCS) on pressure pain threshold (PPT) and muscle activity during scapular plane abduction with 3% body weight load. Fifteen asymptomatic male adults with upper trapezius latent trigger point (LTrP) (PPT<2.9 ) participated in this study. Pressure algometer was used to measure PPT and surface electromyography was used to record upper, middle arid lower trapezius, serratus anterior, infraspinatus and middle deltoid muscle activity and relative ratio during scapular plane abduction between pre- and post-intervention. There was a significant increase in upper trapezius PPT after a 90-second SCS (p<.05). The activity of the upper trapezius and middle deltoid was significantly decreased (p=.014, p=.001), coupled with a decreased muscle activity ratio between the upper and lower trapezius (p<.05). These results indicate that the SCS may effectively deactivate upper trapezius activity, thereby alleviating muscle balance and reducing pain sensitivity.

Foot posture is important in the development of the musculoskeletal structure in the lower limbs because it can change the mechanical alignment. Although foot orthotics are widely used for the correction of malalignments in the lower extremities, the biomechanical effects of wedges have not yet been cleared. The aim of this study was to investigate whether medial wedges affect the electromyographic (EMG) activity of the knee and hip joints in healthy adults that are performing one leg standing. Seventeen healthy volunteers performed the one leg standing under two foot conditions: A level surface, and a medial wedge. The subjects' EMG data for the gluteus maximus (Gmax), gluteus medius (Gmed), tensor fasciae latae (TFL), biceps femoris (BF), vastus lateralis (VL), and vastus medialis oblique (VMO) were recorded, along with the surface EMG, and all were analyzed. The EMG activity of the Gmed and TFL had significantly decreased under the medial wedge condition during one leg standing. Further study is needed in order to investigate whether medial wedges influence the EMG activity and kinematic data of the knee and hip joints as well as the ankle joints in adults with flexible flatfoot, while they are performing one leg standing.

Trunk injection of nematicides was applied to prevent pine wilt disease (PWD). Although the trunk injection of nematicides was effective to PWD prevention, it was not effective to a vector, Monochamus alternatus. Thus, This study was investigated for the insecticidal activity and the effect of oviposition deterrence by injecting to pine trees with systemic insecticides such as Acetamiprid SC 10%, Imidacloprid DC (20%), and Thiamethoxam DC (15%). As a results, mortality of M. alternatus adults was 100% at 56 days after trunk injection. Percentage of M. alternatus adults moved to a young black pine tree by trunk injection of Imidacloprid DC (20%) and Thiamethoxam DC (15%) in screen cage (4.0×2.0×2.5m) was 76.7% and 70.0%, respectively. But the mortality of M. alternatus adults showed 100%. Percentage of M. alternatus adults moved to the treated and untreated young black pine trees by trunk injection of Acetamiprid SC (10%) in screen cage (4.0×2.0×2.5m) were 25.9% and 49.5% at 1st day and 3rd day after treatment, respectively. Percentage of M. alternatus adults oviposited to treated pine logs at 3month after trunk injection of liquid mixture of Acetamiprid SC (10%) and Emamectin benzoate EC (2.15%) in screen cage (72×72×100㎝) was 25%. But, untreated pine logs was 100%

Movement of adult Monochamus alternatus was investigated on young black pine, Pinus thunbergii, trees for about one month in a screen cage. Number of pine trees to which M. alternatus females and males moved during the experimental period was 6.4±1.4 and 7.2±1.5 out of 15 trees, respectively. Adult females and males moved to 0.2±0.1 and 0.3±0.1 tree per day, respectively. A 74.6 and 80.7% of adult females and males moved at night (17:00-08:00) to other trees. After moving, most beetles (72.6% of females and 76.0% of males) stayed on the tree to which they moved for one to two days. Some beetles stayed for up to seven days.

We examined the relationship between breakfast eating, nutrient intake, and health outcomes using dietary intake, anthropometric, and biochemical measurements in Korean adults. Data from the 2007 National Health and Nutrition Survey were obtained, and 2,514 adults aged 20 to 64 years were analyzed. The prevalence of skipping breakfast, using a 24-hour diet recall, was 54.5% in the 20-29 age group, 31.2% in the 30-49 age group, and 19.2% in the 50-64 age group. In the 20-29 age group, waist circumstance and serum cholesterol were significantly higher in breakfast skippers than in breakfast eaters. In the 30-49 age group, breakfast skippers had higher triglyceride levels than breakfast eaters. Energy intake of breakfast skippers in every age group was significantly lower than that of breakfast eaters. Furthermore, in the 20-29 and 30-49 age groups, the percent of energy from carbohydrates in breakfast skippers was significantly lower than that of breakfast eaters, whereas the percent of energy from lipids in breakfast skippers was significantly higher than that of breakfast eaters. Additionally, in the 20-29 and 30-49 age groups, breakfast eaters showed higher carbohydrate and iron intake per 1,000 kcal than breakfast skippers and lower lipid intake per 1,000 kcal than that of breakfast skippers. Breakfast skippers showed intakes of less nutrients than EAR was higher than breakfast eaters except vitamin B2 and calcium intake in males of the 20-29 age group. In conclusion, nutrition education, and policy should be implemented to teach the importance of breakfast, appropriate dietary intake, and proper food choice for each age group.

This study was to investigate the effects of upper and lower limb composing patterns of PNF(proprioceptive neuromuscular facilitation) on the static balance ability by 20 subjects for 6 weeks. This study was measured left one leg standing and right one leg standing with closed eyes on Good Balance system. These results led us to the conclusion that the mean speed of X, Y direction, COP(center of Pressure) velocity moment showed a statistical decrease when applying post-exercise. The above results from this study indicated that upper and lower limb composing patterns of PNF exercise has improved the static balance ability. As a result, this study showed that upper and lower limb composing patterns exercise improve the ability of balance in young adults. Based on this study, it may be applied to old people.

The purpose of this study is to investigate the effects of closed and open kinetic chain exercise for increasing knee joint function on the knee position sense in the normal adults. Thirty normal adults(male 15, female 15; mean age: 22.13±2.58 years) were participated in this study into two groups, each with 15 people. The group I was trained that closed kinetic chain exercise on the knee joint and the group II was trained that open kinetic chain exercise on the knee joint. Exercise programs performed for 4 weeks, 3 times a week were using Shuttle 2000-1 closed kinetic chain exercise and Knee Extensor open kinetic chain exercise(HUR, Filand). The results of this study were as follows: 1) There were statistically significant decreasing of measuring error degree in 0-20。were found between before and after training in closed kinetic chain exercise(p<.05). 2) There were statistically significant decreasing of measuring error degree in 21-40。were found between before and after training in closed kinetic chain exercise(p<.05). 3) There were statistically significant decreasing of measuring error degree in 41-60。were found between before and after training in closed kinetic chain exercise(p<.05). 4) There were statistically significant decreasing of measuring error degree in 0- 20。were found between before and after training in open kinetic chain exercise(p<.05). 5) There were statistically significant decreasing of measuring error degree in 21-40。were found between before and after training in open kinetic chain exercise(p<.05). 6) There were statistically significant decreasing of measuring error degree in 41- 60。were found between before and after training in open kinetic chain exercise(p<.05). In conclusion, these results suggest that closed and open kinetic chain exercise has increased in the knee joint proprioception between before and after training. Especially, closed kinetic chain exercise could be more useful intervention than open kinetic chain exercise for increasing proprioceptive sense.

In the previous study, the plant essential oils such as clove bud , thyme white and garlic oils gave potent toxicity with the range of 1.5 to 4.5×10-3 ul cm-3 of LC50 values against Bemisia tabaci. Based on the bio-assay results, three plant essential oils(clove bud, thyme white and garlic) were applied to 30% emulsion type. The 100, 200 and 400 fold dilution of these emulsions was showed mild toxicity under port scale treatment against Q biotype. At each fold dilution, clove bud showed 44, 26 and 14%, and thyme white produced 44, 39 and 27%, respectively. Of garlic emulsion, its toxicity was evaluated with 27, 26 and 11%, respectively. But, in case of clove bud and thyme white mixture, their toxicity was more good under the mixture than under the single treatment. Mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed potent activity with 86% mortality. And also 200 adding to 400, and 400 to 400 exhibited 61%, 76%, respectively. These essential oil mixtures showed similar strong toxicity against B biotype under port scale test. In particular, the mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed the highest synergistic effect. Toxicity to plants, except the 100 fold dilution of these emulsions was not observed.

The bean bug, Riptortus pedestris (=clavatus) Fabricius (Hemiptera: Alydidae) is a serious pest of soybean in many countries. It enters a reproductive diapause in the winter by short day length (＜13.5 h.) in Korea and Japan. The combined effects of temperatures (25℃ and 8℃) and day lengths (10L:14D and 14L:10D) upon the termination of the male"s diapause were studied. The combinations are ① HTLD = 25℃, 14L:10D treatment for 1, 2, 3 weeks and 30 days, ② HTSD = 25℃, 10L:14D treatment for 1, 2, and 3 weeks, ③ LTLD→HTLD = 8℃, 14L:10D treatment for 1, 2, and 3 weeks followed by HTLD treatment, ④ LTSD→HTLD = 8℃, 10L:14D treatment for 1, 2, and 3 weeks followed by HTLD. The amount of aggregation pheromone components secreted was adopted as the criteria for diapause termination in males. Males did not secrete aggregation pheromone under HTSD conditions. However, the males treated with HTLD for more than 21 days secreted significantly higher amounts of aggregation components, (E)-2-hexenyl (Z)-3-hexenoate and (E)-2-hexenyl (E)-2-hexenoate, compared to the control or HTSD treatments. The three components of the aggregation pheromone were secreted by the 14%, 29%, and 100% males treated with HTLD for 7 days, respectively. However more than 83% of the HTLD-treated males secreted all three components by the 30<SUP>th</SUP> day under the treatment. In comparison, the pheromone amounts secreted by the males treated with LTLD→HTLD or LTSD→HTLD were equal or less than those secreted by males with continuous HTLD treatment.

Purpose : In order to verify using Convergence Insufficiency Symptom Survey(CISS) is proper method to distinguish convergence insufficiency(CI) group and normal binocular vision(NBV) group in adults. Methods : 97 subjects 19 to 35 with normal VA and no strabismus participated in this study. Phoria, positive fusional vergence(PFV), nearpoint of convergence(NPC) and accommodation convergence/ accommodation(AC/ A) of 97 were measured. Results : According to criteria, 62 subjects were included in this study and analysed with CISS. Nine subjects had CI and 53 had NBV. General symptoms of CI group were significantly greater occurrence of Jose concentration, tiredness, sleepiness, uncomfort, double vision and blurring in that order. A significant difference between CISS seore of CI subjects (mean±SD: 25.67±7.67) and NBV group(l2.74 ±4.80) were found(p=O.OOO). The area under the ROC curve was 0.955 indicating outstanding discrimination using the CISS. Using seores of 21 or higher to denote CI, a sensitivity of 88.9% and specificity of 98.1% were obtained. Conclusions : The results suggest that the CISS is a valid instrument for differentiating adults with symptomatic CI from those with symptomatic NBV. Adopting score 21 as cutoff value, it is proved that distinguishing Cl from normal is most precise. Additionally, Adults in this age group were able to respond to a broad range of symptom questions associated with CI. It. therefore, demonstrates CISS is a valid preliminary examination to scan CI patient.

The bean bug, Riptortus clavatus Thunberg (Hemiptera: Alydidae), is a pest of soybeans and tree fruits. It enters reproductive diapause during winter. We studied the effect of different combinations of temperature, day length, and treatment period on the termination of diapause in R. clavatus using adult females collected in October and November 2006. Ovarian development was used to determine diapause termination. The treatments were: ① HTLD, 25℃, 14L:10D treatment for 1, 2, 3 weeks and 30 days, ② HTSD, 25℃, 10L:14D treatment for 1, 2, and 3 weeks, ③ LTLD, 8℃, 14L:10D treatment for 1, 2, and 3 weeks followed by HTLD for 3 weeks, and ④ LTSD, 8℃, 10L:14D treatment for 1, 2, and 3 weeks followed by HTLD for 3 weeks. The HTSD treatments did not affect ovarian development, and resulted in no significant difference in the number of mature eggs in ovaries or the percentage of diapause-terminated females compared to the control females before treatment. The percentage of females that terminated diapause was significantly higher in the HTLD treatment than in the HTSD treatment. The HTLD treatment for more than 14 days increased the percentage of diapause-terminated females, accelerated the development of the ovaries, and increased the number of mature eggs in ovaries. Compared with the HTLD or HTSD treatments, the LTLD or LTSD treatments followed by the HTLD treatment accelerated ovarian development and increased the number of ovipositing females. The pre-LTSD treatment for 1 week was enough to increase the number of eggs oviposited.
