Background: The purpose of this study was to enumerate the annual morbidity and mortality incidence and estimate the direct and indirect costs associated with occupational injuries and illnesses in Bangkok in 2008. In this study, data on workmen compensation claims and costs from the Thai Workmen Compensation Fund, Social Security Office of Ministry of Labor, were aggregated and analyzed. Methods: To assess costs, this study focuses on direct costs associated with the payment of workmen compensation claims for medical care and health services. Results: A total of 52,074 nonfatal cases of occupational injury were reported, with an overall incidence rate of 16.9 per 1,000. The incidence rate for male workers was four times higher than that for female workers. Out of a total direct cost of $13.87 million, $9.88 million were for medical services and related expenses and $3.98 million for compensable reimbursement. The estimated amount of noncompensated lost earnings was an additional $2.66 million. Conclusion: Occupational injuries and illnesses contributed to the total cost; it has been estimated that workers' compensation covers less than one-half to one-tenth of this cost.

We study how to determine backorder cost at the warehouse in a one-warehouse/N-retailer distribution system such that channel efficiency (minimizing total system costs) is improved. We define backorder costs as compensation that the warehouse pays to the retailer for the number or orders delayed due to stockout at the warehouse. We answer two questions : (1) "Should the warehouse compensate for his backorder\ulcorner" and (2) "Is there any equilibrium for both the warehouse and retailer while they are seeking for their own profits\ulcorner" We show that : (1) "The warehouse should pay backorder costs for the sake of channel efficiency." and (2) "There exists an equilibrium that is infiuenced by the amount of compensation." First, we prove the existence of a mutually acceptable equilibrium for both the warehouse and the retailer, which is different from Nash equilibrium because they independently maximize their respective profits with incomplete information about each other. Second, we prove that the equilibrium moves to a point such that channel efficiency is improved if the warehouse compensates the retailers for his backorders. We show the existence of an optimal compensation that minimizes total system costs. Third, we show that the amount of optimal compensation increases as the ratio of mean lead time for the warehouse to that for the retailer increases.ouse to that for the retailer increases.

As a result of accepting the '71 FUND Convention and enforcing the Oil Pollution Compensation Act 1992, we observed some benefits and costa. This paper analyses those benefits and costs and suggests se-veral key policy recommendations for the estasblishment of an effective oil pollution compensation regime in Korea. This paper identifies the said benefits and costs as follows : First, by establishing the oil pollu-tion compensation system as same as the international level, most of small and medium size of oil pollution damage which are caused by coastal tankers will be compensated by FUND. Second, most of oil pollution damage which are not covered by '69 CLC will be compensated by FUND. Third, some parts of FUND Contribution Fee and CRISTAL Contribution Fee to be charged by major oil companies will be doubled. However the limit of international oil pollution compensation system and the loophole outside the Oil Pol-lution Compensation Act 1992 suggest followings : 1) Radical risk management and insurance manage-ment of ocean going tanker owners, 2) Establishment of oil pollution claim settlement system, 3) Enforce-ment of crew and ship management for coastal tanker and 4) Establishment of Korean P & I Club.

This paper compares the accounting standards for stock option of Japan and Korea. Especially, tire setting process of accounting standards for stock option, accounting methods and disclosures for stock option in two countries are analyzed. The results provide that two countries shaw different characteristics in accounting standards for stock option. First, in Japan, acquired services are reported as compensation costs and capital adjustments. On the other hand, in Korea, in case of cash-settled share- based payment transactions, acquired services are reported as compensation costs and capital adjustments, but in case of equity-settled share- based payment transactions, acquired services are reported as compensation costs and debt. Second, when tire stock option rights are abandoned, they are reported as extraordinary items in Japan and are reported as other surplus in Korea. Third, though both countries do not choose specific stock option pricing model, Japan prefers Black-Sholes Model and Korea regards binomial model as proper model.

In the field of ergonomics, it is evident that participatory action research methodology could contribute to reduce risk factors of work related musculoskeletal disorders(WMSDs). The objective of this study was to evaluate the effectiveness of a participatory ergonomics in reducing the incidence rate and severity of WMSDs in the tire manufacturing company. In this study, an action committee comprising 13 members was organized in the tire manufacturing company. The action group participated at every research process, education and training, assessment and intervention of risk factors, and early detection and management of WMSDs during the 3 years(2004-2006). The prevention programs contributed to an overall reduction in incidence rate by approximately 37.2%, and lost workdays and workers' compensation costs by approximately 55.1%. But, the incidence rate increased 29.0%, and compensation costs increased 59.0% in the first-year setting programs, and both the incidence rate and compensation costs decreased after the second-year managing programs. And, the reduction rates(63.2%) of insurance cases is higher than that(9.7%) of non-insurance cases. The results showed that participatory ergonomics programs may be effective in reducing the incidence and severity rate of WMSDs.

In the uniform price electricity market or bilateral electricity market, the energy transactions in which the network is not considered and ISO's system operation costs which ISO try to minimize are settled separately. In this paper, transmission loss, one of the ISO's system operation costs, was dealt. The conventional marginal loss allocation method gives economic signals but three aspects have to be considered; excessiveness, arbitrariness and cross-subsidy. In this paper, marginal loss compensation efficiency method was suggested which consider those aspects of the conventional marginal loss allocation method. Also the characteristics of the marginal loss compensation efficiency were analyzed in the appendixes. And simple 2-bus system and IEEE 14 bus system were used to explain these characteristics.

The purpose of this study was to estimate the socioeconomic costs resulting from alcohol drinking among adolescents as of 2006 from a societal perspective. Methods: The costs were classified into direct costs, indirect costs, and other costs. The direct costs consisted of direct medical costs and direct non-medical costs. The indirect costs were computed by future income losses from premature death, productivity losses from using medical services and reduction of productivity from drinking and hangover. The other costs consisted of property damage, public administrative expenses, and traffic accident compensation. Results: The socioeconomic costs of alcohol drinking among adolescents as of 2006 were estimated to be 387.5 billion won (0.05% of GDP). In the case of the former, the amount included 48.25% for reduction of productivity from drinking and hangover, 39.38% for future income losses from premature death, and 6.71% for hangover costs. Conclusions: The results showed that the socioeconomic costs of alcohol drinking among adolescents in Korea were a serious as compared with that of the United States. Therefore, the active interventions such as a surveillance system and a prevention program to control adolescents drinking by government and preventive medicine specialist are needed.

Licensing contracts between partners in International Joint Ventures(IJV) have not only aspects of relation contract, which is interdependent and long-term cooperative relationships in interpartner but also aspects of discrete contract which is exposed to opportunistic risk caused by IJV partners who maximize individual profit instead of joint payoff maximization. In this circumstance, appropriate compensation structures such as lump-sum and royalty can reduce conflicts and spur interpartner cooperation. In addition, compensation structures that stipulate each party's rights, duties, and responsibilities under various sets of environmental conditions have strong implications for transaction cost minimization and joint payoff maximization. On the other hands, compensation structures such as lump-sum and royalty in IJV licensing contract have benefits and costs depending on IJV partners uncertainty, partner dependency, and environment uncertainty. Therefore, the purpose of this paper is to empirically show how partner uncertainty, partner dependence and environment uncertainty influence compensation structure chosen by licensor in IJV.

Boulder detection methods and its compensation is discussed with consideration of boulder conditions in soft ground tunneling by shielded TBM. For analysis of proper compensation methods for boulder obstruction, its removal costs and cases on eight projects are presented. Compensation for boulder obstruction removal by volume or weight is not practical for most tunneling situation, but compensation by crew time is probably the most equitable method. If boulders are anticipated on project, boulder removal plan must be considered with proper equipment selection.

The purpose of this study was to investigate the association of obesity with medical care use and costs according to overall diseases, cerebrovascular diseases (CVD), ischemic heart disease (IHD), hypertension (HTN) and diabetes mellitus (DM). The final sample was a group of persons who were free of diseases mentioned above and were not underweight. Their baseline screening program data and health insurance contribution data were connected with a 7-year medical claim database. The participants were classified according to their baseline BMI into normal, overweight, obese, and severely obese groups. Given the disease type, the total costs of DM showed the largest difference in each obesity group in both males and females. Also, the pharmacy costs for DM were more relevant than any other type of service to the obesity level. Considering the high prevalence of obesity and the relevantly increased medical care use and costs, there is a need for reduction in medical costs through obesity prevention efforts.
