This article examines two important issues of the demand for payment by the beneficiary and the payment by the guarantor to the beneficiary under the revised Uniform Rules for Demand Guarantee (URDG) published by ICC, which are called URDG 758 and effected on July 1, 2010. Here, after first briefly defining the concept and nature of the demand for payment, this article discusses various issues surrounding the demand: By whom, where and how the demand has to be made; which documents are required in demanding the payment; how much amount can be demanded and paid; when and where the payment has to be made and which currency has to be used for the payment. The demand for payment has to be made by the beneficiary to the guarantor on or before expiry of the guarantee at the place of issuance of the guarantee unless any other place is specified in the guarantee. The demand has to be made in paper form unless the guarantee requires an electronic form. Unless otherwise expressly stipulated in the guarantee, the demand must be supported by a statement by the beneficiary indicating the applicant is in breach of the underlying contract. Also the demand must identify the guarantee under which it is made, and the time for examination by the guarantor starts on the date of identification. The demand cannot be for more than the amount available under the guarantee. When the demand is complying the guarantor must pay the amount demanded. The payment has to be made at the branch or office of the guarantor that issued the guarantee unless any other place is indicated in the guarantee. The payment has to be made in the currency specified in the guarantee, unless the guarantor is unable to make payment in that currency due to an impediment beyond its control or any illegality under the law of the place for payment. In case of "extend or pay" or "pay or extend" demands, the demand is deemed to be withdrawn if the extension is granted. But if not, the demand has to be paid without any further demand by the beneficiary.

The priority job training program is one of key training programs in Korea. This training program has some fundamental problems. The process of selecting the detailed training jobs does not reveal the true training demand of industry sectors. The contracting-out process and control mechanism of the priority job training program show several weaknesses from the points of success conditions of contracting-out public services. In this paper, I proposed development strategies of the priority job training program. The contract period should be longer than one year so that the training institutions may invest for improving quality of training in the longer perspective and reduce transaction costs. The training fee pay mechanism should be more performance-based.

Uterotonics have the ability to contract uterus. Such plants might be useful in augmenting or inducing labour, expelling retained afterbirth and for abortifacient purposes. Limitations associated with conventional treatments have made herbal medicines a feasible alternative for the management of these conditions. The aim of this study was to evaluate the contractile effects of Uvariodendron kirkii extracts on isolated uterine strips of female Wistar rats. Isolated strips of Wistar rats' uteri were treated with 20, 40, 80 and 160 mg/ml concentrations of Uvariodendron kirkii aqueous extract. The plant extract was also tested against prostaglandin and oxytocin induced uterine contractions. Uvariodendron kirkii extract concentrations (20, 40, 80 and 160 mg/ml) increased the frequency of uterine contraction (16.53, 25.12, 33.48 and 56.39 percentages respectively) compared to the control. The graded extract concentrations caused a significant increase in amplitude (force) of uterine contractions by 2.87, 9.22, 16.37 and 24.32 percentages respectively. The concentrations significantly increased the frequency of oxytocin induced uterine contractions by 6.92; 28.31; 47.06, 58.78 percentages respectively. The graded extract concentrations also significantly increased the amplitude of oxytocin induced uterine contractions by 6.07; 9.40; 15.19 and 23.56 percentages respectively. Uvariodendron kirkii extract concentrations significantly increased the frequency and amplitude of prostaglandin induced contractions. The percentage increase in frequency was 11.44, 8.92, 20.65 and 35.71 at 20, 40, 80 and 160 mg/ml respectively. The mean amplitude of prostaglandin induced uterine contractions also increased (4.75, 3.89, 8.29 and 15.91% at 20. 40, 80 and 160 mg/ml respectively). The extract caused a dose dependent increase in uterine frequency and amplitude of contraction. The findings of thisstudy are useful in generating a novel uterotonic agent that will be useful in augmenting labour or in expelling retained after birth in cattle. More studies at molecular level will further elucidate the plant mechanism of action.

The purpose of this study was to investigate the current status of metal pollution in the sediment from rivers, lakes, and streams in active gold mining districts in Ghana. Two hundred and fifty surface sediment samples from 99 locations were collected and analyzed for concentrations of As, Hg, Cr, Co, Cu, Fe, Zn, Pb, Cd, Ni, and Mn using inductively coupled plasma-mass spectroscopy (ICP-MS). Metal concentrations were then used to assess the human health risks to resident children and adults in central tendency exposure (CTE) and reasonable maximum exposure (RME) scenarios. The concentrations of Pb, Cd, and As were almost twice the threshold values established by the Hong Kong Interim Sediment Quality Guidelines (ISQG). Hg, Cu, and Cr concentrations in sediment were 14, 20, and 26 times higher than the Canadian Freshwater Sediment Guidelines for these elements. Also, the concentrations of Pb, Cu, Cr, and Hg were 3, 11, 12, and 16 times more than the Australian and New Zealand Environment and Conservation Council (ANZECC) sediment guideline values. The results of the human health risk assessment indicate that for ingestion of sediment under the central tendency exposure (CTE) scenario, the cancer risks for child and adult residents from exposure to As were $4.18{\times}10^{-6}$ and $1.84{\times}10^{-7}$, respectively. This suggests that up to 4 children out of one million equally exposed children would contract cancer if exposed continuously to As over 70 years (the assumed lifetime). The hazard index for child residents following exposure to Cr(VI) in the RME scenario was 4.2. This is greater than the United States Environmental Protection Agency (USEPA) threshold of 1, indicating that adverse health effects to children from exposure to Cr(VI) are possible. This study demonstrates the urgent need to control industrial emissions and the severe heavy metal pollution in gold mining environments.

Recently, not only around Korea but also other countries shows a pattern of arising high-rise building construction project which was delayed or aborted during global economic crises and recession. Although the market starts to stretch, It is getting competitive to win a contract in high-rise construction project between contractors due to lack of competitive advantage especially to Korea contractors. To get that, Korean contractors needs lifting equipment plan. But currently, they depend on the empirical methods and that cause schedule delay, not controlled cost management problem. Therefore, this research is to improve the accuracy of Lifting plan by analyzing the current issues of Lifting plan system and deducing the types of failures with planning factors, as well as analyzing the impact on schedule and cost control and safety management by each failure mode. Also, by analyzing detail risk factors per Lifting Equipment with FMEA, to infer the critical risk factor on high-rise construction project.

Judging from the past cases, the contractor has frequently suffered losses caused by disapproved requests or reduced payments since it has not known the conditions of the contract or it has filed a claim to the owner without any proper claim system. Therefore, the existing claim process needs to be reformed. In order to reform the claim process, the contractor should consolidate the organizational structure, grant accurate duty assignments to the claims manager, implement regular staff training on how to deal with claims. In addition to this reformation, the contractor needs to improve the management of construction period and process control, and manage related documents thoroughly. Regular meetings are also necessary in claims. This study attempts to prove the effectiveness of the reformed process applied to Project "A", where the owner was responsible for the delayed supply of materials, inaccurate oral instructions, insufficient information on the work, and frequent changes of design. The project was completed in 96 months, which was extended by 34 months from the initial construction period of 62 months. The reformed claim process is expected to be of great help not only to largescale construction works but also to smallscale ones.
