There are a number of industrial complexes which could be a source of heavy metal (loid)s contamination of arable soil in Gyeongnam province of South Korea. Heavy metal (loid)s accumulation of plant is more related to the concentration of plant available heavy metal (loid)s in arable soil than that of total heavy metal (loid)s. The objectives of this study were 1) to examine heavy metal concentrations in soils located near industrial complexes in Gyeongnam province and 2) to determine the relationship between concentration of plant available heavy metal (loid)s and chemical properties of soil. Soil samples were collected from 85 sites of arable lands nearby 7 industrial complexes in Gyeongnam province. Total heavy metal (loid)s concentration, available heavy metal (loid)s concentration, and chemical properties of collected soils were measured. The mean concentrations of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) in the soils were $5.8mg\;kg^{-1}$, $1.3mg\;kg^{-1}$, $0.03mg\;kg^{-1}$, $51.5mg\;kg^{-1}$, and $68.7mg\;kg^{-1}$, respectively. Total concentration of Cd and Zn in arable soil located near ${\nabla}{\nabla}$ industrial complex exceeded the warning criteria ($4mg\;kg^{-1}$ and $300mg\;kg^{-1}$ for Cd and Zn, respectively) as described by in the soil environmental conservation Act of Korea. The concentration of plant available heavy metal (loid)s was negatively related to the soil pH and available Pb and Zn concentrations had relatively high correlation coefficient when compared with other heavy metal (loid)s. The concentration of plant available Pb and Zn was negatively related to that of organic matter (OM). Based on the above results, it might be a good soil management to control pH and OM concentration with soil amendments such as lime and compost to reduce phytoavailability of heavy metal (loid)s in arable soil located near industrial complex.

1. 방동저수지 상류 5개 토지이용별 유출수량과 수질조사를 실시하고 비점오염원 원단위를 산정 하였다. 산지에서 SS 84kg/ha/년, BOD 4.2kg/ha/년, COD 15kg/ha/년, T-P 0.1kg/ha/년, T-N 1.1kg/ha/년으로 배출부하원단위가 가장 작았다. 거주지역에서 SS 319kg/ha/년, BOD 34kg/ha/년, COD 98kg/ha/년, T-P 5.6kg/ha/년, T-N 8.7kg/ha/년으로 배출부하 원단위가 가장 많았다. 2. 비점오염원은 강우-유출과 관련이 있어 전체 비점오염원의 약 46%가 7~8월에 유출되며, 건기인 10월에서 4월까지는 연간 총량의 약20%, 5월에서 9월까지는 약80%가 유출된다. 3. 유기물질인 SS, BOD, COD는 거주지역에서, 영양물질인 T-N은 논 밭지역에서 T-P는 논 밭 거주지역 및 방목지에서 많이 유출되고 있다. 4. T-N, T-P 등 영양물질이 농지에서 많이 유출되어 저수지와 같은 폐쇄수역에 부영양화로 인한 수질악화의 원인이 된다. 비점오염원이 우기에 집중배출되어 공공수역에 큰 오염원으로 작용하므로 도시하천을 이용한 비점오염원 관리방안과 비점오염원 발생원 저감방안을 적극 추진하여야 한다.

Objectives: Although electro-acupuncture is being utilized to reduce weight in Korea, its usefulness in obesity management has not been fully evaluated yet. The objective of this study is to evaluate the effect of Electro-acupuncture on thigh circumference. Methods: 12 healthy volunteers participated in this study. We measured the circumference of both thighs, and treated the thicker one with transcutaneous electro-acupuncture at 8 acupoints, 10 times in total. The electrical parameters were : 1st step frequency set was at 15Hz and the treatment proceeded for 50 minutes, 2nd step at 50Hz for 10 minutes and at 3rd step the acupunctures were removed and electrodes were attached on the lower limb at 166Hz for 15 minutes. In order to evaluate the effect of the treatment, total body weight, percentage of body fat and thigh circumference were measured 4 times. Before the treatment, after 5th and 10th treatment and 1 month after completion of the whole treating procedure. Statistical significance(P<0.05) was determined using the Wilcoxon signed rank test. We did not control diet, exercise and lifestyle of the volunteers. Results: No significant change was shown in body weight after 10 times of treatment. Yet the thigh circumference of effect group significantly decreased after 5th treatment and 10th treatment. The circumference of control group that was not treated by electro-acupuncture significantly decreased too. At first, difference between the two thighs in circumference was obvious, but no difference was left after 10 times of treatments on the thicker thigh. Percentage of body fat was significantly decreased. 1 month after having completed the treatment, there was no significant difference of body weight, thigh circumferences and percentage of body fat. Conclusion: These results suggest that electro-acupuncture effectively regulates regional fat, body fat percentage and body shape.

The purpose of this study is to provide the basic data in order to improve the quality of charged recuperation facilities which are specialized in the old. after finding out the satisfaction degree for the services which are provided in the current charged recuperation facilities specialized in the old and surveying the services which are demanded by users. As for the research method. the subjects were 88 family members of the users in the five charged recuperation facilities, which are specialized in the old and located in Seoul and Incheon. The survey research was executed from 27th July to 15th September, 2002. Then the collected data were analyzed by using the SPSS 10.0 for windows program. The research results are as follows. Firstly, in the satisfaction degree of the user's family about the daily service showed the highest satisfaction degree for the kind service of the staff to the users. In the satisfaction degree about the specialized service of the user's family, the satisfaction degree was high in bedsore prevention, periodical health care, proper medical treatment, family counsel, and adequate disease management. In the satisfaction degree about the facility and environmental service, the satisfaction degree about the surrounding environment of the facility or safety facility, and the comfort condition was high. In the satisfaction degree about the services related to the local society, it was high in the hospital and medical-related field. Secondly, in the demanded services, the demanding degree for worship, mental and spiritual nursing, hospice, funeral service, family meeting, and support for the special vehicle were not so high, but it was shown that they were generally demanded. Thirdly, it was shown that the provided services had an overall high satisfaction degree. In the service satisfaction degree according to the general characteristics of the user's family, it was recognized that there was a significant difference between the distinction of sex and local society related services. Also, there was a significant difference in the satisfaction degree between age and specialized service. Through the above research results, detailed rehabilitation programs such as linguistic treatment and working treatment should be more and more compensated in order to supplement the insufficient points of the services provided by the charged recuperation facility specialized in the old. Additionally, the correlation with the local society such as education and training for specialized human labor, close cooperation among the facilities, and positive participation in local society events are thought to be reinforced.

Objectives : Based on the system and control activity for the monitoring system made of components for infection control at dental hospitals and infection rate reporting, and the role of trained infection control staff, this study tried to understand approaches to the effective infection control program by surveying infection control at dental hospitals in Korea. Methods : The survey was conducted from December 14,2010 to January 31,2011 for 121 dental hospitals in Korea. For statistical analysis, PASW Statistic 18 was used. Results : And following conclusions were reached. 1. As for the infection control system at dental hospitals, 54.7% has an infection control committee, 58.7% infection control staff, 78.5% infection control rules, and 39.7% annual infection control plan and record. 2. As for surveillance indexes to report infection rates, 50.4% has the reporting system for staff's exposure to infectious disease and needle pricking. The average number of exposures to infectious disease was $0.28{\pm}2.23$ and that of needle pricking was $1.83{\pm}5.39$. 3. As for infection control indexes, it was reviewed whether infection control rules were implemented according to operation agents, general hospitals were more active in staff infection control, and hospitals annexed to a dental university or special legal entity were more active in microorganism control. As for use of personal protection gear, there was no significant difference among operation agents. More than 71% of operators and their assistants said they did not replace their masks between patients. 4. As for personnel indexes for effective infection control staff, most hospitals designated dental hygienists, which was followed by dental doctors (or doctors). Where their workload was reviewed, the ratio of other work such as treatment was relatively higher than that of infection control (n=71). Conclusions : These results show dental hospitals in Korea have a certain level of infection control system. As infection indexes are managed mainly for staff members, patient monitoring is needed, and trained and effective infection control staff should be designated. This study reviewed surveillance, infection control and personnel indexes. And further studies are needed in the future.

One of most important problems in the Monsoon Asia today is the production of rice paddy to meet the needs of the ever increasing population. Diversemeans are being employed to meet this demand, both by increasing productivity of existing farm land and by bringing further areas into cultivation. The primary step in either field is to ensure that there is sufficient moisture in the soil to suit the paddy, and at the same this means that excess moisture has to be drained off the land, while in others irrigat ion has to be employed to bring sufficient water to an area. In view of the fact that the project comprises a huge amount of earthwork, it can be carried out by extensive use of construction machinery in order to shorten the period. As farm ditch has a comparatively small section with shallow cutting depth, inaddition, there is lack of access road in the field, the excavation equipment with bulldozer or tracter-shovel (backhoe) type are not applicable because there are mostly adapted for the excavation of deep and wide section. Mini-backhoe with its bucket width not larger than 0. 3m, and width of blade not larger than 1. 00m seems to be more adaptable. About 80% of excavation of ditch section will be done by the machinery while the other 20% of excavation together with the finishing of the section are supposed to be done by man-power. The embankment of ditch section can be compacted by the crawler of backhoe when it is moving along the ditch for excavation. However, Lowland paddy field in the Monsoon Asia are made particulary in rain season, therefore, heavy machinery is not easy excavation for ditch. It is very important to know exact ground support power of the working site and select machines with corresponding ground pressure. Ground support power is variable subject to quality and water content of soil and therefore selection of machines should be made duly considering ground condition of the site at the time of construction works. Farm ditches dug and compacted by mannual labar are of poor quality and subject to destruction after one or two years of operation. On the other hand, excavation and compaction by bulldozer is not practical for ditches. Backboe is suitable for slope land, but this is required cycle time of bucket excavation and dumped out. If a small-scale farm ditch trencher adaptable to lowland paddy field is invented, such a machine could greatly accelerate the massive construction work envisaged in many countries and thus significantly speed up the most difficult part of irrigation development and management in Monsoon Asia.
