Objective : Private health insurance coverage in Korean medicine has been reduced since October 2009 for preventing unnecessary utilization. The aim of this study is to identify how private health insurance coverage reduction affects on the Korean medicine utilization. Method : We analyzed the Korea Health Panel data from 2008 to 2012. Panel negative binominal regression model was used to analyze the relationship between private health insurance coverage reduction and utilization of outpatient service. Panel tobit regression analysis was used to identify the relationship between private health insurance coverage reduction and health expenditure of outpatient service. Results : Private health insurance coverage reduction significantly dropped both utilization and health expenditure of outpatient service by 9%, 9.22% respectively. In addition, therapeutic utilization significantly decreased up to 10%. Conclusion : Private health insurance coverage reduction seems to have an effect to reduce both utilization and the health expenditure of Korean medicine outpatient service. This effect was more noticeable in the therapeutic utilization. Thus, more elaborate policy will be needed to prevent unnecessary utilization of Korean medicine.

Using the most recent dataset of Korea and U.S. household finance, this study analyzed demand and adequacy of private pensions for pre-retirees. For this purpose, 2013 Korean Retirement and Income Study (KReIS) of national pension research institute in Korea and 2013 SCF (Survey of Consumer Finances) of FRB in U.S. were used. For comprehensive comparisons of the two countries, this study classified the private pension into sub-categories such as personal pension, corporate pension, and retirement benefits, and used three different criteria including ownership, accumulated present value of each pension, and income replacement ratio of each pension. After controlling for other factors, educational level of householder and household income were critical determinants of size and adequacy of private pension in both countries. Different from Korean households, householders' gender, marital status, and health status had an important effect on the private pension size and adequacy in the U.S. In addition, home ownership significantly increased only private pension adequacy in Korea, and also increased ownership rate, size, and adequacy of private pension in the U.S. Results of this study provide useful implications for future pension system and policy in Korea.

This study was conducted to evaluate needs and intention of hospitals and clinics to join network with private health insurance, and to discover obstacles of participation of the networks. We carried out the questionnaire survey of the network managers of 236 medical institutions between December 27th, 2005 and January 25th, 2006. The result showed that the participation intention of network were different to the type of hospitals. Primary care clinics answered that participation intention and possibility were low. Secondary care hospitals was relatively affirmative regarding a network participation. Tertiary hospitals responded that they need the network with private health insurance, but participation possibility was lower than needs. The reason is that they worried about the side effect of the network with private health insurance. Depending on the type of hospitals, expected benefits from networking with private health insurance were different. We found that hospitals which already had affiliation with other hospitals answered in the affirmative regarding the network with private health insurance. In conclusion, to increase the effectiveness of network systems between hospital and private health insurance, the network is expected to consider different needs of the each hospital.

본 연구는 노인의 공적 이전소득과 사적이전 소득이 노인의 삶의 만족도, 자존감에 어떠한 영향을 미치는가를 이해하는 데 목적을 두고 있다. 분석방법으로는 빈도분석, T-test, 아노바, 회귀분석을 실시하였다. 연구결과 다음과 같은 점을 논의 하였다. 첫째, 노인의 공적이전소득과 사적이전소득에 따른 삶의 만족도, 자존감이 유의하게 나타났다. 둘째, 사적이전소득중 자녀로 부터의 보조금과 공적이전소득은 많을수록 삶의 만족도와 자존감이 높게 나타났다. 셋째, 사적이전 소득 중 민간.개인보조금은 적을수록 자존감이 높게 나타났다. 이와 같은 결과에 근거하여 다음과 같은 제언을 하였다. 노인의 경제적 자립이 자존감을 높이는 계기가 됨을 알 수 있었다. 따라서 좀 더 실질적이고 구체적인 공적이전체계가 뒷받침되어야 한다. 또한 사적이전소득 중 자녀로 부터의 보조금이 삶의 만족도에 영향을 주므로 가족 간의 지속적인 관심과 유대가 필요하다.

In order to investigate the prevalence and the factors related to the depression and burnout among private practice physicians, a SDS(self-rating depression scale) and MBI(Maslach burnout inventory) -based questionnaire study was performed on 344 private practice physicians in Kwangju and Chonnam area. The results were summarized as follows. 1. Mean SDS score was 38.3 in total subjects and the prevalence rate of depression was 48.8%. As for the frequency order of the items of the SDS, decreased libido, diurnal variation and hopelessness were relatively high, and suicidal rumination, constipation and agitation were noted low. 2. Noticeable factors related with depression were smoking, coffee use, sleeping time and satisfaction with income. 3. As a result a factor analysis with the MBI data, five factors named as emotional exhaustion, depersonalization, personal accomplishment, involvement and self-interest were extracted. Statistical analysis of the data demonstrated that 48.8% of the physician sample reported high scores on emotional exhaustion, and 45.3% scored high on depersonalization. Personal accomplishment scores remained high with 45.3% reporting high personal accomplishment. 4. Variables related to the burnout were age, sleeping time, family size religion, medical speciality, duration of practice setting, visiting patient number, closing day per month and job satisfaction. 5. In the relationship with depression, burnout was closely related to depression. Above results showed that the high percentage of private practice physicians experiencing depression and burnout suggests the need for further research to establish trends, to identify causal factors, and to develop avenues to reduce stress.

Ultra-wideband(UWB) is a killer technology for short-range wireless communications. In the past, most of the UWB research focused on physical layer but the unique characteristics of UWB make it different to design the upper layer protocols than conventional narrow band systems. Cross-layer protocols have received high attention for UWB networks. In this paper, we investigate the performance of two physical layer schemes: Time Hopping Binary Pulse Position Modulation(TH-BPPM) and Time Hopping Binary Pulse Amplitude Modulation (TH-BPAM) with proposed private MAC protocol for UWB ad-hoc networks. From pulse level to packet level simulation is done in network simulator ns-2 with realistic network environments for varying traffic load, mobility and network density. Our simulation result shows TH-BPAM outperforms TH-BPPM in high traffic load, mobility and dense network cases but in a low traffic load case identical performance is achieved.

The purpose of this study was to analyze the differences in the expenses of private education and the economic preparations for old age according to household income and consumption wants for education in mothers with school-aged children. The data used in this study were collected from 416 mothers with school-aged children aged 8 to 19 years old living in Daegu. The data analysis methods adopted for the study were two-way ANOVA and Scheff$\acute{e}$ test. The results of this study were as follows: First, there were differences in the private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of low household income, the mothers with high consumption wants for education spent more money on academic education and music, fine arts or physical education than the mother's with low consumption wants for education. On the other hand, in the group of mothers of high household income, the mothers with low consumption wants for education spent more money on academic education and spent less money on music, fine arts or physical education than the mothers with high consumption wants for education. There were no meaningful differences in the group of mothers of middle household income. Second, there were differences in the perceived burden of private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of middle household income, the mothers with low consumption wants for education perceived there was a higher burden for private education expenditure than the mothers with high consumption wants for education. Third, there were differences in the expenditure preparation for old age and the economic preparation behavior for old age according to the level of household income. The mothers with high household income spent more money on preparation for old age and did well in economic preparation behavior for old age than the mothers with middle and low household income.

Security supports are a significant factor in the design of mobile ad hoc networks. In the dynamic topology where the node changes frequently, private key generation and revocation for newly joining and leaving nodes must be considered. In addition, the identities of individual nodes must be protected as well in mobile networks to avoid personal privacy concerns. This paper proposes ID-based private key revocation scheme and non-interactive key agreement scheme in anonymous MANETs. The proposed scheme provides the user privacy using pseudonyms and private key generation and revocation schemes with consideration of dynamic user changes. Therefore, our schemes can be applied in dynamic and privacy-preserving MANETs which are helpful to share multimedia data.

In this study we overviewed the early private learning for children in Korea. For last 20 years the number of children who were involved in it increased and the starting age had been lowered. Now more than 90% of the children are exposed to it before going to school. Mean number of private lesson per child is between three to four (33.6%). 32.7% of preschoolers take more than 5 kinds of private lesson per week. Because of the frantic enthusiasm of the parents, most preschools and kindergartens are providing extra curricula in their programs. The main problem of the learning in Korea is that it does not run by government or universities with educational purposes but by commercial companies for profit.
