In this paper, a large-scale, wide-area storage system based on IP is proposed which is under development. OASIS is a storage system enforced with very high-scalability up to hundreds and thousands of clients over IP network, and it is able to extend the service to the wide area network. For this purpose, we adopt an storage interconnection technology based on IP, the object based storage technology and a clustered server architecture which provides high-scalability and availability to our system. This system can be utilized to provide network storage service which gains more reality with the incoming FTTH and WiBro services.

In order to discuss the implications for demographic changes due to an aging society, this study sought to verify the effect of generational age with a focus on the case of the national housing scale transaction in Seoul Seocho-gu. For the result, variance and linear regression analysis, and when the analysis showed a significant correlation between age and transaction price, and corrected the trading region and year, it was also confirmed that the higher the age in most regions, the lower the trading price tendency. Based on the results of this analysis, efforts to improve the adequacy and fairness of pricing in trading cases, and the direction of policy change due to the aging of the population were discussed, and on the basis of this, we even proposed measures for the support of the policy authorities. In addition, the management condition of individual communal houses was an important factor in the sale and the lack of utilization of Internet-based platforms was expected to be the cause of the low price sale. However, due to the use of 2nd order data on real trading cases, the direction of subsequent research was presented together with respect to the limitations of not being able to control a wider variety of individual characteristics.

In many enterprises, the extent and the frequency of damages incurred due to the unethical behavior of the members of the organization have not reduced, but rather the magnitude and frequency of damages have been increasing. Research at an organizational level is necessary at this point in time, to investigate the contributing variables that cause this unethical behavior, the measures to manage them, and the control variables that can reduce unethical pro-organizational behavior. Therefore, this study seeks to explore perceived organizational support and psychological entitlement as leading factors of unethical pro-organizational behavior, based on the theory of social exchange, and to examine the reaction mechanism between these variables. This is particularly because a large number of the current labor force belongs to the millennial generation (born after 1978) or Generation Y, and their sense of psychological entitlement has been problematic in their organization. The effect of perceived organizational support on unethical pro-organizational behavior and the effect of psychological entitlement on unethical pro-organizational behavior were examined through a review of existing literature, and an empirical analysis was conducted to investigate the moderating effects of psychological entitlement on perceived organizational support and unethical pro-organizational behavior. A regression analysis was conducted based on the valid data of 185 members of an organization who belong to the millennial generation, and the analysis results showed that a sense of psychological entitlement had a moderating effect between perceived organizational support and unethical pro-organizational behavior. Based on these findings, this paper proposes theoretical and practical implications for unethical pro-organizational behavior and psychological entitlement, and hopes to contribute to expanding research in this area.

The data of Duroc swine species that were born from 2000 to 2014 excluding missing ones collected by Korea National Institute of Animal Science were used in the present study. After removing missing data we used 9756 of productions data and 1728 of reproductive reference of breeding research to study the level of inbreeding and to investigate the impact on the reproductive traits, production traits. The correlation of reproductive traits and inbreeding coefficient are -0.07, -0.08 for total number pigs born, number of pigs born alive respectively and birth weight per litter is -0.10, number of pigs born alive per litter to 21days is -0.06 and body weight per litter to 21days is -0.09. The correlation coefficients of the inbreeding coefficients of reproductive traits are shown within 10% with negative correlation (P < 0.05). Days of 90kg and Backfat in the correlation coefficient and inbreeding coefficient production traits were not observed significant correlations, Average daily gain was investigated by the positive correlation of 0.05. According to the above results, the inbreeding level gave a negative effect on the improvement of the breed traits, investigating a relatively high compared to a negative effect on other traits. But overall correlation degree is less than 10% was observed. This inbreeding coefficient has not been clearly observed due to degeneration of the average inbreeding coefficients of these generations was maintained within 10% of the population. The scale of the experimental group was about 150 degree pig husbandry is very small compared to the advanced countries. However, the level of inbreeding in the population group with the appropriate mating combinations is maintained below 10% of population is thought to be small and can minimize the effects of inbreeding degeneration. further testing utilizing this selection is constantly considered to be necessary.

This paper estimates the effect of household size and its changes on income inequality. Household formation is an important inequality-reducing mechanism through income pooling and collective consumption. The increase in small households, reflecting lower fertility rate and the increase in both nuclear and old families, has weakened the inequality-reducing effect of household formation. In contrast, additional workers in households and their income have strengthened the inequality-reducing effect of household formation. Given the increasing trend of old families, these results suggest for a balanced policy package that promotes employment and does not discourage co-habitation in order to maintain the inequality-reducing effect of household formation.

In recent years, better quality in power electric services is being required with the development of information industries and the improvement of living standards. Also, the small scaled dispersed storage and generation (DSG) systems are being interconnected with the distribution systems and customers by the influence of the recent issues such as deregulation and global environmental problems in power system. Under these circumstances, it is very important to maintain the customer voltages within allowable limits for the distribution system which is located at the most sensitive part in the power system. To overcome these problems, this paper shows the basic concepts of FRIENDS which is considered as one of the power delivery system in the near future and also presents an evaluation method on the impacts of customer voltages by operation models of FRIENDS. The FRIENDS can change the system configuration in a flexible manner by using the static switches and offer the different power qualities in power services through the power quality control centers which play the most important role in FRIENDS. Numerical examples are shown in order to indicate the efficiency of the proposed method.

The purpose of this research is to investigate the factors which effect the intention to reemploy after the retirement and the mediation effect of the social capitalism for retired and prospective retired baby boomers. Starting from 2010, baby boomers have been retiring at a large scale. However retirement at a large scale without securing provision for fiancial wise in later life can lead to many issues regarding social and fiancial wise such as instability of labour market and increase of spending in society welfare cost and such on. Change of individual's self prospective and institutional support to help prepare find new career for next 3decade after the retirement needs to be concretized. The results of this study suggest that the management orientation affects the social capital positively and the autonomous orientation does not affect the relationship between career orientation and social capital. In terms of the relationship between career orientation and reemployment intention, management orientation does not affect the intention of the entrepreneur but affects the reemployment intention positively, while the autonomous intention affects neither entrepreneurial intention nor reemployment intention (+), Respectively. Social capital has a positive effect on the intention of reemployment, and the mediating effect of social capital on the relationship between career orientation and reemployment. Also, while in the work force, potential retiring baby boomer workers should be systematically supported with education, training and reemployment program based on individual's career orientation and allowing them to stay for a longer period in the labour market can be the implication to the solution for the economic stability and increasing social cost such as public pensions.

본 연구는 한국 기혼여성의 차별출산력 분석으로 인구학적 특성으로 연령, 초혼연령, 혼인상태 및 가족유형(가구구성)을 포함하구 사회경제적 특성으로 거주지역, 교육정도, 경제활동상태, 직업 및 주택 점유형태를 포함하였다. 통계청의 인구주택총조사를 원자료로 하여 인구 및 사회경제적 변인들이 출산력에 미친 영향을 파악하기 위하여 다변량 분석기법을 이용하였다. 초혼연령이 높아지면서 출산수준은 현저히 낮아졌으며, 배우자와 동거하는 기혼부인의 출생아수가 가장 많았으며, 이혼한 경우 가장 적었다. 자녀양육을 위한 부모의 도움을 받을 수 있는 3세대 이상 가족이 동거하는 가구의 경우 출산수준이 상대적으로 높았다. 그러나 최근 이혼이 급증하면서 유배우 상태가 빠르게 감소하구 1세대나 독신가구의 증가와 3세대 이상 가구의 감소는 앞으로의 출산수준을 더욱 빠르게 할 것이다. 사회경제적 특성별 차이에서도 유사한 현상을 발견할 수 있었다. 도시규모가 클수록, 학력수준이 높을수록, 전문사무직종에 근무할 경우, 그리고 전월세로 거주할 경우에 출산수준이 낮았다. 사회경제적 특성별 출생아수의 차이는 1980년에 가장 컸으며, 그 후 지속적으로 감소하고 있다. 더욱이 출산수준이 높은 농촌인구의 급감, 교육수준의 향상으로 교육간 차이의 감소 농어업직에 종사하는 기혼여성의 감소 등은 전체적인 출산수준을 빠르게 감소시키는 요인으로 작용하였다. 기혼부인의 특성별 출생아수의 차이는 여전히 뚜렷하였으나 그 차이는 점차 감소하고 있다. 또한, 출생아수가 많은 집단의 구성비가 빠르게 줄어드는 것을 감안하면 전체적인 출산수준의 감소는 더욱 빨라질 수 있다. 앞으로 2005년 인구주택총조사의 결과가 발표될 때 그 간의 특성별 출생아수의 차이와 인구구성비의 변화를 분석하면 대체출산수준에 근접한 1980년 이후 빠른 출산력의 감소원인을 이해하고 출산력의 장래 변화를 효과적으로 예측하는데 도움이 될 것이다.

올 1월 말 바르셀로나에서 열린 3GPP Next Generation Access Requirement AH는, 10여 년전 4G LTE가 처음 논의될 때와 비교하면 열기가 뜨겁다는 것은 여전하지만, 주역들은 많이 바뀌었음을 느낄 수 있었다. 4G 논의 때에는 유럽, 일본이 주도하고 북미, 한국은 따라가는 상황이었다면, 5G 논의는 중국이 전면에 나서고 한국, 유럽이 따라가는 패턴을 보여주고 있다. 엄청난 규모의 중국 내 TD-LTE 시장을 무기로 차세대 기술과 표준논의를 주도하고 있는 중국 사업자와 제조업체의 위상을 실감할 수 있는 자리로 보인다. 우리 나라는 LTE 기술 개발과 상용화 시점, 보급율 현황 등에서 타국의 추종을 불허하는 스피드를 보여주었고, 덕분에 우리 국민들은 세계에서 가장 앞선 모바일 서비스를 누리고 있고, 그 여세를 몰아서 5G 논의의 물꼬를 튼 것도 사실이다. 그러나 시장에서는 시작은 반이 아니고 시작일 뿐이다. 본 무대를 어떻게 연출해 가느냐에 따라 주도권을 계속 가져갈 수도, 한순간에 밀려날 수도 있는 것이 냉엄한 현실이다. 금년부터는 5G에 대한 기술 표준화가 본격화 되는데, 이와 병행해서 기술 개발, Joint Trial, 시험 주파수 할당, C-P-N-D-M 생태계 확보 등의 작업이 정신없이 진행될 것으로 예상된다. 한정된 국가적 자원을 효율적이고 효과적으로 활용하기 위한 산학연관의 지혜가 더욱 필요한 시기가 오고 있으며, 이번 5G특집이 그 고민의 계기가 되면 좋겠다.
