Background : This study was conducted to investigate the current situation of medical supply purchasing and stock management at general hospitals having more than 150 beds in Korea and to find methods of effective purchasing and optimal stock management. Methods : Survey was done from staff at the purchasing departments of 229 general hospitals throughout Korea. Data collection was done using a structured questionnaire between January 3 to March 15, 2001. The survey form was returned from 88 hospitals (rate of return: 38.4%). Results : Firstly, 13.6% of the hospitals did not carry the optimal stock of medical supplies, the lead time optimal stock was 3 weeks or longer in 64.4% of the hospitals. Secondly, since 69.8% of the hospitals showed passive attitude toward training on purchasing management and stock management techniques. Thirdly, as for the question on the presence or absence of a deliberation committee for purchasing of new medical supplies, 60% of the hospitals with less than 300 beds did not have one, and 9.4% of the hospitals opened the deliberation committee less than twice a year. Conclusion : At the time of purchasing new medical supplies, purchasing should be done according to the decision by the deliberation committee so that no deduction is made at the time of claiming insurance, and by setting a certain period of time, purchasing of those medical supplies that were not purchased during this period needs to be done according to the decision by the deliberation committee.

In this paper, we obtained some supportive evidence for the long-run PPP relationship concerning the Korean Won currency. Previous tests of PPP in the bilateral exchange rates of the Korean Won rate vis-a-vis the U.S. Dollar have been exposed to the lack of power problem. We argue that their failure to find PPP relation in Korean Won rates was due to the low power of Augmented Dickey-Fuller tests or the Engle-Granger two-step tests applied to the Korean exchange rate data with short sample period. En attempting to alleviate this low power problem, we used the error-correction model test and the Johansen test for bilateral long-run equilibrium relationships between exchange rates and price indices from Korea's major trading partners. It is surprising that our evidence supporting for long-run PPP in Korean Won rate contrasts sharply with Bahmani-Oskooee, Moshen and Rhee, Hyun-Jae(1992)'s.

This study investigates aircraft lessor business models by studying cases and interviewing experts to analyze investors and business strategies of aircraft lessor. The results confirm that there is a wide range of investors including institutional investors, financial institutions, insurance companies, corporations, and wealthy individuals for aircraft lessor. Aircraft lessors can be categorized based on its required rate of return (cost of capital) into bank-investing core, institutional investor-investing value-added, and hedge fund-investing opportunistic. Aircraft lessor decides leasing rate by aircraft purchasing price and lessee's credit rating. Core aircraft lessors invest in new aircrafts for new placement or sale-and-leaseback strategy requiring little technical risk in aircraft, value-added lessors invest in middle-aged aircrafts for re-leasing, opportunistic lessors invest in old aircrafts for freighter conversion or part-out strategy requiring high level of expertise. This study provides insights for future Korean aircraft lessor establishment and investment.

Purpose - The primary objective of this study is to investigate the impact of employee characteristics on employees' preference towards corporate pension products. This study can provide a guidance for maximization of benefits for employees and their affiliated corporation. Employee characteristics include average length of labour, wage system of annual salary, age, types of interest rates and size of corporation. Existing research generally concentrate on vitalizations of corporate pension product raising an imperfection, improvements, tax benefit analysis and legal consideration. Thus, this study intensively analyses the effect of employee attributes on firms' decision for corporate pension products, such as DB(defined benefit) and DC(defined contribution) type. Research design, data, and methodology - The data were collected using self-administrated questionnaire survey on corporate pension products from CEOs or HR directors 250 foreign-invested companies', purchasing pension plans in practice with domestic financial trustees (insurance companies, banks and security companies). Hypotheses testing was conducted using Logistic Regression analysis with SPSS/PC+ 21.0. Results - The findings of the study are as follows. Employees with the long length of labour are more likely to have DB plan; more likely to prefer DC plan with the dividend distribution product regarding the types of interest rate. SMEs(less than 100 employees) are more likely to select DC plan whereas high fluctuation in wage with annual salary has no impacts. In addition, the ages has no significant effect on the preference. Conclusions - This study has examined with the empirical testing that employees' variable attributes and qualities are one of the vital factors for corporation pension plan selection. Currently, majority employees are highly likely to join DB plan and Defined interest types. Corporation with less than 10 employees prefer IRP scheme while most of corporation are intended to join DC plan. In a very near future, corporation more than 300 employees will be required to purchase mandatory plan under national regulation. For maximization of employees' contentment to corporation pension insurance and for complementing the flaws of existing plans, the future studies shall also research in a perspective of employee benefit.

Background: The rise in national health care costs has emerged as a global problem given the ever-aging population and rapid development of medical technology. The utilization of interventional pain management has, similarly, shown a continued rise worldwide. This study evaluates the differences in the medical costs in the field of interventional pain treatment (IPT) between two countries: Korea and Japan. Methods: Korean medical insurance costs for 2019 related to pain management focused on IPT were compared to those of Japan. Purchasing power parity (PPP) was used to adjust the exchange rate differences and to compare prices in consideration of the respective societies' economic power. Results: The cost of trigger point injections in Japan was 1.06 times higher than that of Korea, whereas the perineural and intraarticular injection prices were lower in Japan. The cost of epidural blocks was higher in Japan compared to Korea in both cervical/thoracic and lumbar regions. As for blocks of peripheral branches of spinal nerves, the cost of scapular nerve blocks in Japan was lower than that in Korea, given a PPP ratio 0.09. For nerve blocks in which fluoroscopy guidance is mandatory, the costs of epidurography in Japan were greater than those in Korea, given a PPP ratio 1.04. Conclusions: This is the first comparative study focusing on the medical costs related to IPT between Korea and Japan, which reveals that the costs differed along various categories. Further comparisons reflecting more diverse countries and socio-economic aspects will be required.

목 적: Ir-192 고선량율 근접치료(HDR Brachytherapy)선원에 대한 다양한 측정절차의 효율을 서로 비교할 것이며, 측정 장비의 추가 구입 없이 대안으로 새롭게 만든 PMMA (polymethylmethacrylateplastics: $C_5H_8O_2$) plate phantom에 대한임상에서의 적합성과 유용성을 알아 보았다. 대상 및 방법: 세 가지 형태(Well type chamber, Source calibration jig, PMMA plate phantom)의 측정 시스템을 이용하여 측정값을 비교하였다. Source calibration jig와 PMMA plate phantom을 사용 했을 때에는 Farmer type chamber를 이용하여 측정하였으며, 각각 5회씩 측정하여 제조업체의 측정치와 비교하였다. 또한 새로운 선원을 교환 할 때마다 제조업체로부터 선원과 함께 제공되는 제조업체의 측정치를 본 연구의 측정치와 비교하여 방사능의 정확도를 평가 하였다. 결 과: Well type chamber, Source calibration jig, PMMA plate phantom를 사용한 Ir-192 선원의 측정결과 제조업체 측정치와의 상대오차에 대한 RMS (Root Mean Square)값은 Well type chamber에서 0.6%, Source calibration jig에서 1.57%, PMMA plate phantom에서는 2.1%를 나타내었다. 또한 평균 오차에 대한 편차는 Well type chamber에서 $-0.2{\pm}0.5%$, Source calibration jig에서 $0.97{\pm}1.23%$, PMMA plate phantom에서는 $-0.89{\pm}1.87%$를 나타내었다. 결 론: 본 연구를 통해 실험한 세 가지 형태(Well type chamber, Source calibration jig, PMMA plate phantom)의 측정 시스템의 결과에서 나타난 것처럼, Well type chamber를 이용한 측정결과가 가장 우수하게 나타났다. 또한 측정 장비를 구입하지 않고 대안으로 새롭게 만든 PMMA plate phantom의 결과 권고안 ${\pm}5%$를 초과하지 않으므로 임상에서 유용하게 사용 할 수 있을 것이라 생각되어진다.
