This study was carried out to investigate the pollution of heavy metals in soil of seven stations from the upper spot (Yeungchun Dam) of Kumho River to the downstream(Gangchang Bridge). The results obtained were as follows: 1. The content of heavy metals in soil of Kumho River basin was highest at Gangchang Bridge [expresed in $\mu$g/g : Mn(246.0), Cd(1.90), Fe(551.2), Cu(108.2), Zn(86.4), Cr(80.2), respectively]. Whereas, the content of heavy metals expect for Mn, Cu was lowest at Yeungchun Dam [Cd(0.40), Fe(548.0), Zn(30.7), Cr(6.2), respectively] Also, the content of Cr, Zn was increased when the sampling areas are changed from upstream to downstream except for Hayang Bridge, and Hayang Bridge was the diverging point of the heavy metals content. 2. There were relatively correlated between Mn : FE, Cu, Zn, Cr, Fe : Cu, Zn, Cr(0.40 < $\left$\mid${r}\right$\mid$$ < 0.70), and were high correlated between Cd : Mn, Fe, Cu, Zn, Cu : Zn, Zn : Cr(0.70 < $\left$\mid${r}\right$\mid$$ < 0.90). Particularly, there was higest correlated between Cd : Cr, Cu : Cr(0.90< $\left$\mid${r}\right$\mid$$ < 1.0)

Objectives: The purpose of this study was to measure estheticians' grip and pinch strength in the hand parts and identify related factors according to general characteristics. Methods: A Jamar dynamometer was used to measure grip strength and a Jamar pinch gauge was used to measure tip, palmar and lateral pinch strength. General data were collected through a questionnaire survey among 116 estheticians from 31 skin care centers and spas. Results: The subjects' mean grip strength was 23.95 kgf for the right hand and 23.42 kgf for the left hand with the dominant right hand recording slightly higher mean grip strength. Their mean pinch strength was the highest with lateral pinch(right 4.89 kgf, left 4.69 kgf), which was followed by palmar pinch(right 3.77 kgf, left 3.88 kgf) and tip pinch(right 2.29 kgf, left 2.25 kgf), in that order. Conclusions: The grip and pinch strength of the hand parts was high when estheticians' commonly used both hands for massage instead of just one. The use of both hands is recommended to protect the hand parts during massage.

Objectives: By comparing and examining how important issues concerning industrial health information for workers are viewed in other advanced countries, it is intended to ascertain problems in the approach found in Korean legislation and obtain legal and policy implications. Methods: The results of a survey were introduced and analyzed through a comparative method for each case after investigating in detail what and how important issues surrounding workers' right to know industrial health information are reflected in the legislation of Germany, the U.S., the U.K., and Japan. Based on the results of this comparative analysis, theoretical and policy implications and legal policy improvement tasks were drawn to strengthen workers' right to industrial health information for each case in Korea. Results: For access to industrial health information, most of the other advanced countries clearly stipulate a right to access for current and past workers and/or their representatives. As a result, workers or their representatives do not need to use the Information Disclosure Act to access exposure records, and there is no debate over the Information Disclosure Act. In other words, industrial health information is focused on ensuring free access to workers or their representatives and is not interested in reporting it to the government. Conclusions: In order to strengthen workers' right to know about industrial health, it is most important to address the legal issues related to this right, which is considered insufficient by comparative law. This should start with a concrete and effective definition of what and how to guarantee workers' rights to industrial health, such as the right to freely access industrial health information, including for retired workers and bereaved families of deceased workers.

Being different from 20th Century, the right of disabled have attracted much social attention. In reality, the disabled still suffered or not properly respected, thereby a little far less in achieving the quality of life. The purpose of this research was to examine the fitness between the persons with limited mobility and their living environment. Small group workshop with three persons with limited mobility were used for utilized. Living behavior and physical environmental characteristic of dormitory house and interaction between them were identified. Major problem appeared to be accessibility which include the path, room size and furnishing. Even though the dormitory satisfied the government requirement legally. Substantial problems were found because of resident real life. This implied deep consideration beyond Act needed to create a right to robust environment toward persons with limited mobility.

The computation of gravity anomalies by multi pole expansion is derived and compared with exact calculation for right rectangular prisms and right circular cylinders. For sources near field points, the multipole expansion results in a better approximation in volume integrals than in surface integrals. Nonetheless two approximate methods are coincident in the far-field of the general geophyical prospecting.

Analysis for landslides was studied in framework of Chungju dam right abutment, 6.5km northeast of Chungju city. $5.5{\times}10^6m^3$ landslide materials were excavated during dam construction for safety of the Chungju dam. Geology of study area is composed mainly of meta sediments such as dolomitic limestone, quartzite and schist which are dipping toward the Nam Han river. Scanline survey of discontinuities was performed for slope stability, resistivity exploration was performed for the evaluation of potential failure plane, and direct shear strength test of rocks and soils was performed for the effect on landslide. Monitoring systems of tiltmeter, tensiometer, ground water observation hole and level monument were installed during dam construction and interpreted for the evaluation of slope instability. Kinematic solution of the geological structure and evaluation using safety factor for slope may prove the failure of the slope.

ODA projects such as multi-purpose dam, industrial complex, road construction etc. have resulted in environmental damage and resident relocation including destruction of site of living. Even the grandiose developments as ODA projects have made clear the value clashes between development and environmental conservation, and have brought about conflicts between public interests and public environmental right, and the discordance between public interests and private property rights in the recipient country. This study summarizes and analyses the Korea's ODA projects and will suggest the public participation and governance system based on Saemaul Movement, Strategic Environmental Assessment and Environmental Impact Assessment based on the guideline of OECD DAC, and emphasize Strategic Environmental Assessment and Social Impact Assessment in the procedure of ODA projects. In the future the ODA project should be implemented for the overcome of poverty and response to climate change based on the experience and trial and errors of Korea's compact growth and past ODA projects.

In this study, the observational environment for sunshine duration at Seoul and Daegu Automated Synoptic Observing Systems (ASOSs) was analyzed using a numerical model. In order to analyze the effects of topography and buildings on observational environment for sunshine duration, the model domains including the elevated building and mountainous areas around Seoul and Daegu ASOSs were considered. Three dimensional topography and buildings used as input data for the numerical model were constructed using a geographic information system (GIS) data. Solar azimuth and altitude angles calculated for the analysis period (one-week for each season in 2008) in this study were validated against those by Korea Astronomy and Space Science Institute (KASI). The starting and ending times of sunshine duration observed at ASOSs largely differed from the respective sunrise and sunset times simply calculated using solar angles and information of ASOSs' latitude and longitude, because uneven topography and elevated buildings around ASOSs cut off sunshine duration right after the sunrise and right before the sunset. The model produced the sunshine indices for Seoul and Daegu ASOSs with the time interval of one minute and the period of one week for each season and we compared the hourly averaged indices with those observed at the ASOSs. One week of which the cloudiness is lowest for each season is selected for analysis. Not only the adjacent buildings but also distant buildings and mountain cut off sunshine duration right after the sunrise and right before the sunset. The buildings and topography cutting off sunshine duration were found for each analyzing date. It was suggested that, in order to evaluate the observational environment for sunshine duration, we need to consider even the information of topography and/or building far away from ASOSs. This study also showed that the analyzing method considering the GIS data is very useful for evaluation of observational environment for sunshine duration.

Reliable hazard and risk communication is needed to prevent the safety accident & occupational disease through right use of chemicals and MSDS(Material Safety Data Sheet) is mainly used as such a tool of communication. MSDS policy has been put into effect in order to prevent the safety accident & occupational disease through right use of chemicals and fulfill workers' right to know. If information on MSDS lacks reliability due to its inaccuracy, prevention of the various effects related with environmental safety & health in advance is not possible to achieve. The most essential thing regarding authoring MSDS is to exactly evaluate the composition and ingredients of the chemical and include reliability-guaranteed information. Therefore, in this study reliability was evaluated on MSDSs in 15 aromatic hydrocarbons(benzene, toluene, xylene, etc.) manufacturers and ways to secure reliability of MSDS were suggested. The results showed 93.5% of composition agreement rate and 89% of reliability on each section in MSDSs. In order to curb MSDSs with low reliability, examination on CBI(confidential business information) in MSDS, certification of MSDS, collection and verification of MSDS are suggested.
