The purpose of this study was to identity the probability of cross-contamination from the environment. For this, we examined foodservices at 20 universities/colleges for microbiological analysis of their working facilities and environment as well as their preventive equipment against cross-contamination. Seventy percent of the 20 foodservices were found to maintain one unified working area, which suggests high probability of contamination of food/utensils/equipment in the cooking area by pre-preparation or dish washing. According to the microbiological analysis, the hygiene acceptance ratio of working facilities in the clean zone was 70%, which was higher than the average 45% hygiene acceptance ratio of working facilities in the contamination operating zone. There was a significant difference in the total plate count (P<0.001) and coliform count (P <0.01), which demonstrates that work tables in the clean zone were in a good state compared to those in the contamination operating zone. In the contamination operating zone, refrigerator shelves had a high probability of cross-contamination. Regarding the floor surface and airborne microbes, cooking areas which should be maintained as clean zones had higher cross-contamination probability than those in the contamination operating zone. So corrective actions such as cleaning and sanitizing, keeping dry floors, lowered temperature and humidity, shoe disinfecting facilities, and checking concentrations, are necessary to manage floor surfaces and airborne microbes in the cooking area.

Macrodactyly is one of the most difficult congenital anomalies to treat. Treatment of macrodactyly requires surgical intervention because it gives rise to esthetic, social, and functional disability including difficulty in wearing shoes. A myriad of surgical techniques has been introduced to reduce the size of macrodactyly. However, treatment of toe macrodactyly has not been spotlighted due to less significant functional and social issues compared with finger macrodactyly. We treated two patients with toe macrodactyly by single stage reduction operation.

Flatfoot is a common foot disorder. Some modifications by orthotic shoes for the flatfoot have been prescribed, however their effectivenesses are not fully proven yet. We have tried to validate the effectivenesses of conventional orthotic shoes for the flatfoot patients. We assessed the static and dynamic pressure, dynamic pressure-time integral, and relative impulse with and without wearing orthotic shoes. Thirteen subjects with the flatfoot were included in this study. The results showed the positive effects of orthotic shoes for the subjects. Especially the dynamic pressure-time integral values revealed the significantly reduced values at the medial side of midfoot, which meant the functional improvement of flatfoot status. We have concluded that the use of conventional orthotic shoes for the flat foot patients would be effective for properly selected patients, if there is no other associated abnormality.

OBJECTIVE: To investigate the change in plantar skin temperature in normal subjects wearing five different kinds of insoles. METHOD: Twenty normal subjects were chosen and were made to walk on a treadmill for five 30-minute sessions wearing the same shoes, and wearing five different kinds of insoles (four types were endothermic insoles, but one type was a normal insole) respectively. Subjects sat on a chair for 10 minutes before and after walking. The plantar skin temperature was recorded on 4 sites (from channel 1 to 4) on each left insole. The plantar skin temperature was recorded every 10 seconds for a total of 50 minutes, with T-type Thermocouple(R). RESULTS: There were no statistical differences in the change of plantar skin temperature for each insole before, during and after walking. No statistical differences in subjective thermal sense and Borg Rating on perceived exertion scale for each insole before, during and after walking. Time in peak plantar temperature was 25.9~28.3 minutes (after subjects starts walking), wearing normal insole. CONCLUSION: There was no statistical difference in the change of plantar skin temperature for the five different kinds of insoles However, we found this method to be effective in examining plantar skin temperature during walking.

6.Management situation and using industrial chemicals at some productive manufacturer in Vietnam
Journal of Practical Medicine 2004;471(1):4-6
The investigation was performed on employees and workers who contact with chemicals at 9 institutions using various substances in the process of production of paint, rubber, shoe and wood articles in Ha Noi, Hai Phong and Da Nang. Results showed that the current regulations were not complied preserve and use of chemical substance, without emergency equipments available for working staff and environment. A high rate of workers had not been educate on chemical safety and a high rate of work place and facilities had not guideline for using chemical substances.

Hemiplegic patients with an ankle foot orthosis (AFO) has a tendency to show external rotation of affected side foot. External rotation inhibiting shoes (ERIS) were designed to inhibit excessive rotation of hemiplegic foot. ERIS were applied to two hemiplegic patients who were able to walk independently with a plastic AFO. Both of them showed an excessive external rotation of hemiplegic foot after AFO apply. Each patient tried to walk with a pair of common shoes first and ERIS later. The external rotation angle, step length, stride length, cadence, speed were measured by footprint method. The external rotation angle of hemiplegic foot was significantly decreased with ERIS than with common shoes. However they did not show consistent improvement in the step length, stride length, cadence and speed. We reported that hemiplegic patients who walked with ERIS showed remarkable reduction in excessive external rotation of hemiplegic foot.

OBJECTIVE: To find the most effective lever-point to manufacture the rocker-outsole. METHOD: Ten healthy men were participated. Metatarsal-bar, 12x1x0.5 cm, was clung to the outsole of shoes. In the first experimental-group, we set the center of the metatarsal- bar to an imaginary line which across the center of the 1st metatarsal head with that of the 5th metatarsal head. In turns, we experimented the other groups as moved the center of the metatarsal-bar 0.5 cm backwards, each naming 2nd, 3rd, 4th group. Plantar peak pressures were measured at T0 (whole foot), M1 (heel), M2 (midfoot), M3 (1st, 2nd metatarsal area), M4 (3rd, 4th, 5th metatarsal area), M5 (great toe), M6 (2nd, 3rd toe) and M7 (4th, 5th toe). RESULTS: There was significant decrease in the peak pressure of M3 in the first experimental-group, which the center of metatarsal-bar was set to an imaginary line. CONCLUSION: In the first experimental-group, there was significant decrease in the peak pressure of M3. Therefore, the lever-point of rocker-outsole should be set to an imaginary line which connects the center of the 1st metatarsal head with that of the 5th metatarsal head.

10.Investigation of Floor Surface Finishes for Optimal Slip Resistance Performance.
Safety and Health at Work 2018;9(1):17-24
BACKGROUND: Increasing the slip resistance of floor surfaces would be desirable, but there is a lack of evidence on whether traction properties are linearly correlated with the topographic features of the floor surfaces or what scales of surface roughness are required to effectively control the slipperiness of floors. OBJECTIVE: This study expands on earlier findings on the effects of floor surface finishes against slip resistance performance and determines the operative ranges of floor surface roughness for optimal slip resistance controls under different risk levels of walking environments. METHODS: Dynamic friction tests were conducted among three shoes and nine floor specimens under wet and oily environments and compared with a soapy environment. RESULTS: The test results showed the significant effects of floor surface roughness on slip resistance performance against all the lubricated environments. Compared with the floor-type effect, the shoe-type effect on slip resistance performance was insignificant against the highly polluted environments. The study outcomes also indicated that the oily environment required rougher surface finishes than the wet and soapy ones in their lower boundary ranges of floor surface roughness. CONCLUSION: The results of this study with previous findings confirm that floor surface finishes require different levels of surface coarseness for different types of environmental conditions to effectively manage slippery walking environments. Collected data on operative ranges of floor surface roughness seem to be a valuable tool to develop practical design information and standards for floor surface finishes to efficiently prevent pedestrian fall incidents.
