The purpose of this study was to investigate the actual conditions related to the working environment of radiological technologist who is working in small or medium-sized hospitals or clinics. The results of this study were intended to improve the working environment of radiological technologist and care for patients. For data collection, a structured questionnaire was used as a research tool, and 838 women (52.4%) were used as a general characteristic of 1,598 people subject to this questionnaire. The annual salary of radiological technologists with less than one year experience was 33.76 million won, and the average annual salary of radiological technologists with more than 10 years of experience was 41.33 million won. It showed an increased of 1.84% per year. Among 1,540 radiological technologists, 879 workers were paid holiday work allowances, 340 workers did not, and 321 holiday workers work during the week. In addition, a total of 817 workers received overtime payment, of which 112 received overtime wage on a monthly basis regardless of the overtime hours. In addition, a total of 348 radiological technologists were not paid overtime wage, and 138 workers were included in the basis salary. There were no union in 85% of the them. According to the results of this study, the wages and working environment of radiological technologists in small or medium-sized hospitals or clinics were not appropriate. Therefore, the efforts of the radiological association and its members are necessary to provide a better working environment for radiological technologists. In addition, it is expected that this study will be used as basic data for the association's policy to improve the working environment of members who work in poor conditions.
The impact of global trade on developing countries is a critical subject. Especially in this country, under difficult conditions like political issues with North Korea, achieved a trade surplus of 90.2 billion dollars last year. While the service trade recorded a deficit of 15.7 billion dollars in the same period. According to WTO, services are either the result of a production activity that changes the conditions of the consuming units (transformation services), or facilitates the exchange of products or financial assets (margin services). To unify and compare with the trade and service statistics of countries, they assorted 12 classifications of services like Manufacturing service on physical inputs owned by others, Maintenance and repair service n.i.e., Transport, Travel, Construction, Insurance and pension service, Financial service, Charges for the use of intellectual property n.i.e., Telecommunications, Computer and information services, Other business services, Personal, cultural and recreational services, and Government goods and services n.i.e. Thus, this study is to estimate the international competitiveness of service trade between 2006 and 2015 in Republic of Korea, according to EBOPS 6th. As a result, total service volume of export and import has increased in the last 10 years. Its volume, recently, accounts for 22% of total goods trade. Also the Korean Government can make a supporting policy and decide a supporting business in terms of service trade. Finally, we can find a mutual connectivity within 12 service businesses and between Service and Goods.
It is quite true that the more Korean contractors receive overseas contracts, the more they need guarantees. The top market for them is the Middle East countries, consisting of more than the half of the total amount awarded last year and the trend is increasing as well. The problem, however, is that employers in these countries are reluctant to use international rules for guarantee such as URDG or ISP98 and easily make unfair callings. However, Korean contractors(applicants), especially small and medium sized enterprises(SMEs) tend to hurriedly enter a contract without looking into its contents as well as guarantees. They do not realize the importance of the guarantees until they receive callings from the employers(beneficiaries). Being independent from the underlying contracts, guarantee is the equivalent to cash in that it usually does not require any proof of demand when calling and the guarantor should make a payment within usually 5 business days after the request. It is often observed these days that several Korean SMEs go bankrupt due to liquidity risks after receiving unfair callings from employers in the Middle East countries. In retrospect, some cases could be obviated if contractors were a little more careful in checking the contents of a guarantee at the time of concluding a contract. For example, there is one case where the underlying contract includes a reduction clause in the Advance Payment bond and the guarantee does not have that clause. In the end, the Korean contractor had to take the whole burden of the bond amount though it had finished 81% of the project. Nobody could argue that contractors should take a full responsibility if they fail in their obligations. However, the employer's wrongful callings need to be prevented in the first place, if possible. As there shouldn't be a case where one party is at a disadvantage against the other like the case mentioned above, useful insight is being sought to minimize unfair calling risks for the benefit of the applicant. First, the applicant should carefully look into every detail of the potential guarantee before signing a contract, heeding especially that there is a reduction clause in the AP bond. Second, the governing principles for guarantee should be the ones that are internally used such as URDG758 that is objective in terms of callings given that, for example, it specifies that the requirement for a supporting statement when making a demand is a default rule. It is also recommended that the form of guarantees be the standard demand guarantee. Third, parties involved in issuing guarantees are advised to understand international rules for guarantee like URDG758 and ISP98 and to play a key role in guiding SME contractors in Korea so that they can protect themselves from possible wrongful callings, particularly from employers in the Middle East countries. I hope this study would give a wake-up call for Korean SMEs wishing to do business in the Middle East countries and remind them of the importance of guarantee itself and its governing principles.
This Study reviews theoretical argument about the effect of retirement earnings test on the labor supply of the aged which is controversial issue in OECD countries and analyze the effect on the incidence of re-employment, re-employment period of suspended officials and the possibility of re-retirement through Government Employment Pension Corporation data. It consists of 178,363 public officials who received pension benefit or disability pension in January 2005. The main result of this research shows that public officials re-employed were 8,086 which is 4.5% of total retired, and median survival time of suspended pension payments is 3.3 years. Also the median re-employment period of 100% suspended officials is about 20 month shorter than that of 1/2 suspended officials and it is shown in regression analysis that the possibility of re-retirement by 100% suspended officials is statistically significant higher than those of 50%. It specially expects greater influence if includes in case taking lump-sum or no making effect of re-employment because current system withhold pension payments even by earned income itself. Therefore, this analysis suggests suspension of pension payment properly applied according to the age and income together with "Delayed Retirement Credit" or "Partial Pension" for developmental alternatives of civil servant's suspension of pension payments. Furthermore, It is urgently needed that distinctive quality data about re-employment including earnings to perform deep-empirical research for effective policy. Lastly, it is extremely necessary to reinforce management system of Government Employment Pension Corporation.
Objective : To estimate the socioeconomic costs of obesity in Korea,1998. Methods : The 1998 National Health and Nutrition Examination Survey(1998 NHNES) data was used and 10,880 persons who had taken health examinations were selected for study. Essential hypertension, NIDDM(non insulin-dependent diabetes mellitus), dyslipidemia, osteoarthritis, coronary heart disease, stroke were included as obesity related disease. The data of direct costs of obesity was obtained from the National Federation of Medical Insurance. The category of indirect costs was the loss of productivity caused by premature death and admission, time costs, traffic costs, nursing fees due to obesity. Multiple logistic regression model was developed to estimate prevalence odds ratio by obesity class adjusted demographic and socio-ecnomic factors and calculate PAF(Population Attributable Fraction) of obesity on obesity related disease. And we finally calculated the socioeconomic costs of obesity in relation to BMI with PAF. Results : The direct costs of obesity were 2,126 billion${\sim}965$ billion Won in considering out of pocket payment to uninsured services, and the indirect costs of obesity were 2,099 billion${\sim}1,086$ billion Won. Consequently, in considering out of pocket payment to uninsured services, the socioeconomic costs of obesity were 4.225 billion${\sim}2,050$ billion Won, which corresponded to about $0.094%{\sim}0.046%$ of GDP and $1.88%{\sim}0.91$ of total health care costs in Korea. Conclusions : Obesity represents a major health problem with significant economic implications for the society. This results are conservative estimates as far as all obesity related disease and all health care and indirect costs were not included due to missing information. further studies are needed to caculate socioeconomic costs of obesity more exactly.
The purpose of this study was to investigate the differences of the general characteristics of subjects, the utilizing realities and the degree of satisfaction in the shopping mall and purchasing intention between group I that specializes in fashion design and group II that doesn't specialize in it. The results are summarized as the following six aspects. First, as a result of the general characteristics of subjects and the utilizing realities, the most different variables were the visiting frequency and the goods purchasing frequency. The result indicated that group II took more interests than group I. Second, as a result of the degree of satisfaction according to the factors of the general characteristics of subjects and the utilizing realities in the shopping mall, both group I and group II showed high degree of satisfaction in factor 1 (variety of event) whereas both groups showed relatively low degree of satisfaction in factor 3 (variety of goods). Third, as a result of the degree of satisfaction according to the general characteristics of subjects and the utilizing realities, group I showed significant differences in the degree of satisfaction according to a monthly allowance of pocket money and goods purchasing frequency and group II showed significant differences in the degree of satisfaction according to grade, the utilizing reason, goods purchasing frequency. Fourth, as a result of purchasing intention of fashion goods according to the general characteristics of subjects and the utilizing realities, group I showed the higher purchasing intention of fashion goods in group that the terms of payment was on-line payment than group that they was credit card. On the other hand, group II showed a significant difference in grade, which showed that group that was above third grade had the higher purchasing intention of fashion goods than group that was under third grade. Fifth, as a result of purchasing intention of fashion goods according to the degree of satisfaction, group I showed significant differences in factor 1 and factor 3 among the degree of satisfaction. In other words, group that had high degree of satisfaction in factor 1 showed the higher purchasing intention of fashion goods than other groups and group that had medium degree of satisfaction in factor 3 showed the higher purchasing intention of fashion goods than other groups. In group II, on the other hands, group that had high total degree of satisfaction showed the higher purchasing intention of fashion goods than other groups. Sixth, as a result of relative influencing power of independent variable with respect to purchasing intention of fashion goods in group I, the higher degree of satisfaction in factor 1 and the lower degree of satisfaction in factor 3 showed, the higher purchasing intention of fashion goods showed. As a result of relative influencing power of independent variable in group II, however, the higher grade and the higher degree of satisfaction in factor 1 showed, the higher purchasing intention of fashion goods showed.
Background: From January 2018, a policy was applied to differentially apply the co-payment for medical expenses of 15,000 won or more from 30% to 10%-30% for each medical fee. This policy lowers the burden on the medical use of the elderly, and it is necessary to analyze the effect of the policy by confirming changes in medical use and supply behavior after 2 years. Methods: The National Health Insurance Service's national medical use database was used. As for the analysis method, first, the medical use and medical supply behavior change over the age of 65 years were confirmed, and second, in order to check the net effect of the policy, the 66-year-old as the experimental group and the 63-year-old as the control group were selected as the control group. The propensity score matching was performed using the variables of age, living alone, income quartile, residence, disability, chronic disease, and co-morbid disease scores, and then it was analyzed using the difference in difference analysis method. Results: The share of the number of treatments under 15,000 won decreased from 37.0% in 2017 to 20.2% in 2018, while the share of the number of treatments under 15,001-20,000 won increased from 8.0% to 22.7%. It was confirmed that the reason for the increase in the cost of treatment per treatment was the result of the increase in the amount of physical therapy and examination. As a result of the policy effect, the burden of co-payment per person was reduced, and as a result, the number of hospital visits per person and the total medical cost per person increased. Conclusion: The self-pay rate differential policy reduced the burden of medical expenses for the elderly and confirmed the increase in medical use. However, the interpretation of the increase in medical use was not able to distinguish whether the unsatisfactory medical care was satisfied or the inducement demand. Efficient allocation of resources is a more important point in the future when the super-aged society is in front. It is necessary to prepare a plan to induce rational medical use within a range that does not impair the medical accessibility of the elderly.

The development of public-key-based technique that enables a variety of services(E-government, e-banking, e-payment, etc.) evaluated as having complete safety. On the other hand, vulnerabilities(e.g, heartbleed bug, etc.) are constantly being discovered. In this paper, a public key infrastructure to verify the safety and reliability, the collision rate using OpenSSL key pair was analyzed. the experiment was performed using the following procedure. Openssl was used to create five private certification agencies, and each of the private certificate authority certificates to create 2 million, generating a total of 10 million by the certificate of the key pair conflicts analysis. The results revealed 35,000 in 1 million, 0.35% chance of a public key, a private key conflict occurred. This is sufficient in various fields(E-payment, Security Server, etc.). A future public-key-based technique to remove the threat of a random number generator, large minority issues, in-depth study of selection will be needed.
The purpose of this study was to provide the valid data about residential-linked pension insurance development. The development was a part of national housing projects, which was an incentive for rural living of retired people, in order to relieve residential issues of elderly and revitalize rural communities by residents moving from cities. The insuring intent, decisive insuring factors and the residential service demand degree of people preparing retirement were analyzed. Data was collected in October, 2007. 364 Sample Subjects lived in Seoul Metropolitan area. Firstly, more than 90% of respondents had intention to purchase a residential-linked pension insurance and about 50% of them necessarily desired receiving premium for moving in. This indicated that it could be developed as an insurance which helped to meet housing expenses by housing-linked system, and in the mean time, it met the original purpose of pension insurance as the pension benefit could be guaranteed for all the insurance subscribers. Secondly, the respondents, whose income and private assets were higher, were able to pay more for insurance compared to average. Therefore, It was necessary to regulate monthly insurance bill and the payment period according to asset states of insurance subscribers after establishing certain amount of total insurance payment. Thirdly, by and large, it indicated the tendency that the less they prepare for older age the later they wanted to move into the pension insurance residence. It was inferred that in the case of insufficient preparation for older age, people preferred preparing behind time by postponing move in to moving in early to enjoy retired life, due to uncertainties. lastly, the respondents understood the significance of health, medical treatment and emergency management service and these two services were preferred as essential provided services. Because of the necessity of developing residential-linked pension insurance was found to be positive, further research to find the real cost, directives for operation and institutional support for this type of pension insurance might be needed.

Background: Due to the diversification and advancement of research, researchers have become to deal with a variety of chemical and biological harmful materials in the laboratories of universities and research institutes and the risk has increased as well. Therefore, it is necessary to strengthen the social safety net for laboratory accidents by strengthening the compensation to the level comparable to that of Korean Workers' Compensation & Welfare Service, when the researchers become physically disabled by laboratory accidents. The purpose of this study is to secure researchers' health rights and to create a research environment where researchers can work with confidence by strengthening the compensation to the level comparable to that of Korean Workers' Compensation & Welfare Service. Method: We analyzed the laboratory accidents by year, injury type, severity of accident and disability grade with the 6 year data from 2011 to 2016, provided by Laboratory Safety Insurance. Based on the analysis result, we predicted the financial impact on Laboratory Safety Insurance if we introduce a compensation annuity by disability grade which is similar to Injury-Disease Compensation Annuity of Korean Workers' Compensation & Welfare Service. Result :As of 2011, the insured number of Laboratory Safety Insurance was approximately 700,000. The Average premium per insured was KRW 3,339 and there were 158 claims. Total claim amount was KRW 130 million, whereas the premium was about KRW 2.3 billion. The loss ratio was very low at 5.75%. If we introduce a compensation annuity by disability grade similar to Injury-Disease Compensation Annuity of Korean Workers' Compensation & Welfare Service, the expected benefit amount for 1 case of disability grade 1 would be KRW 1.6 billion, assuming 2% of interest rate. Given current premium, the loss ratio, the ratio of premium income to claim payment, is expected 41.4% in 2017 and 151.6% in 2026. The increased loss ratio due to the introduce of the compensation annuity by disability grade is estimated to be 11.0% in 2017 and 40.4% in 2026. Conclusion: Currently, laboratories can purchase insurance companies' laboratory safety insurance that meets the standards prescribed by Act on the Establishment of Safe Laboratory Environment. However, if a compensation annuity is introduced, it would be difficult for insurance companies to operate the laboratory safety insurance due to financial losses from a large-scale accident. Therefore, it is desirable that one or designated entities operate laboratory safety insurance. We think that it is more desirable for laboratory safety insurance to be operated by a public entity rather than private entities.
