Since the supply of smart phones, a change in mobile environment brought a turning point called a mobile generation. Smart mobile office is a combined form of smart phones' new mobile environment and its social media. A construction of mobile office environment using smart phones brought revitalization of the smart phone market. CRM construction also became new requirements for a customer management. However, based on the current information system audit standard, check fields or check lists are insufficient to apply to audit for CRM construction in a smart mobile office environment. Therefore, this paper proposes a model for auditing CRM system construction in smart mobile office environment. It proposes audit domain and check lists of CRM construction. It also verified whether the proposed model is suitable or not by doing a survey if deduced audit domain and check lists correspond with the purpose of the CRM construction audit during smart mobile office environment. As the result, this study appear to have more than average satisfaction the suitability results were.

At Present, Korea government run the 38 points manned lighthouse, the change of Manned lighthouse that manager live is inevitable in orger to enhanced features as aids to navigation and provide a fore efficient management system. There are "Enhancing management system for Manned Lighthouses" four standards(Function of AtoN, Functionality of wide area management, National policy, Marine culture) for evaluation of Unmanned Lighthouses. After collecting these datas, analyzing it, applying AHP and Likert Scale, we choose base manned lighthouses for shorten restoration time that can manage AtoN far from regional office of Oceans & Fisheries. This paper will support efficient management system for AtoN that were scattered in sea of korea and improvement living environment for lighthouse keepers.

21st century is called as a knowledge based society. It means that a society has to build an efficient information system to store and retrieve their knowledge and information. I think a school library is a base educational institution to teach information skill and a student has to be trained very well to treat information in 21st century. However school library has not been developed enough in Korea, and so I suggest the strategy of school library development for the new millennium. For the purposes, I divide the environmental elements of school library into two parts -external and internal elements of school library environment- and examine them to suggest some policies. Even though the suggestions are still a little fantastic in the situation of scl~ml library in Korea, they should bc objects to be achieved in someday.

한국은 2050년까지 주요 선진국 중에서 고령화가 가장 심각한 사회로 전환되게 될 것으로 예상된다. 기대여명의 증가와 저 출산은 고령화를 더욱 악화시키며, 이는 심각한 사회문제로 발전하게 될 것이다. 이와 같은 문제를 해결하기 위해 한국정부는 2008년에 도시지역에는 주택연금제도를 도입하였으며, 2011년에는 세계 최초로 농촌지역을 대상으로 농지연금제도를 도입하였다. 그렇지만 이와 같은 제도는 설계 당시부터 복지상품이라기 보다는 장기적으로 손실과 수익의 균형에 초점을 둔 금융상품으로 개발되어 실질적으로 노인들에게 크게 인기를 얻지 못하였다. 따라서 본 연구는 농지연금제도를 활성화시켜, 농촌노인들에게 보다 더 많은 혜택을 주기 위해 지역 토지시장을 감안하여 지역별 농지가격상승률을 예측하고 연금액을 산출하였다. 또, 지금까지 사용한 년 혹은 분기별 감정가 대신에 월별, 지역별 실거래 가격을 모형에 적용하여 지역토지시장, 고령화 수준 등 지역 여건에 부합하는 연금액을 산출하였다. 할인율자료도 가장 안정적인 3년 만기 국고채 수익률을 활용하여 미래농지가격을 예측하고, 이를 유동화하여 월 생활자금으로 지급되도록 하였다. 특히 농지규모가 가장 많고, 고령화 정도가 심각하여 농지연금의 잠재적 수요가 가장 높을 것으로 예상되는 경상북도와 전라남도를 사례지역으로 선정하고, 이를 전국평균과 비교하여 지역적인 차이도 함께 분석하였다. 이를 위해 농지가격 및 이자율 시계열 자료의 안정성을 검정하고, 장기농지가격을 예측하였다. 이를 활용하여 경북, 전남, 전국의 노인들의 월평균 지급액을 추정하였다. 분석결과 정책의 잠재적 수요가 가장 높은 두 지역이 가장 낮은 금액이 지급되는 것으로 추정되어 이는 또 다른 지역불균형을 초래할 수 있는 것으로 평가되었다.

The GDP gap (also called the output gap) is the difference between potential GDP and actual GDP. Potential GDP is the maximum sustainable output that is achieved when the resources (labor and capital) are used to capacity. Central banks pursuing price and employment stability consider the output gap as an informative variable for monetary policy since the output gap could be regarded as a proxy of demand-supply imbalances. In this paper, the GDP gap of Korea is decomposed following the filtering method in the previous research, and major factors that affect the variation of GDP gap are investigated based on the decomposed series. The analysis results by the Super Smoother algorithm used in Fox et al. (2003)and Fox and Zurlinden (2006) are found consistent with theory. Much of the variation of nominal GDP gap is explained by Total Factor Productivity(TFP) gap, which is the change of productivity due to recent technological innovation and environmental change. It is also found that variation of terms of trade significantly affects the GDP gap of Korea due to its high dependency on international trade; however, the effect of the domestic price is not negligible like other countries.

The need for integration of knowledge and technology among SMEs has been acknowledged, and lacks ways of convergence in practical education. Therefore contents of convergence in practical education of high quality are needed. In this study, a case-oriented curriculum and contents were developed to enhance employee's skills of SMEs. The curriculum consists of 3 steps. The first step is analysis of trends and current status of convergence of SMEs in the domestic and foreign areas. Thus drawing up measures of standards to analyze a successful case. The second step is collection of materials, and development of models through successful cases of convergence. The third step is the analysis of a curriculum to enhance employees' of SMEs and the development of an education program. This study may lead to strengthening competition of SMEs through knowledge and technology convergence based on developed curriculum.

This study examines the relationship between sentiment of speculators and price movements in the futures markets of WTI crude oil, copper, and wheat during the period 2003~2014 using Granger causality tests. The results indicate that speculative positions overall has no predictive power for returns in each futures market. Rather, returns seem to have effects on speculators' sentiment especially during periods of both economic expansion and recovery. During a recession, meanwhile, changes of speculators' sentiment index in the WTI crude oil and copper markets provide predictive power for returns in a positive direction, suggesting that speculators' pessimistic sentiment aggravates declines in commodity prices. Since the effects of speculative positions on market prices are ambiguous, tight regulations on speculative trading are not advisable. In a bearish market, however, regulatory bodies should consider raising speculative position limits because large speculative short positions and (or) liquidation of index traders' long positions may lead steep price declines.

The key objective of terrorism is to create favorable conditions for certain political, ideological, or religious interests through deliberate social chaos and the spread of fear. Accordingly, terrorist groups rally the means and methods capable of spreading fear among the public through shocking violence. Consequently, as terrorism manifests the progress in modern civilization and the structure of international community, its concepts, means, and methods evolve organically with the progress. The characteristics of the modern terrorism include that it has evolved as a means of war against countries by non-state militant groups, and suicide terrorism is spreading like epidemic as it fits the strategies of Islamic extremist and terrorist organizations as a part of international politics based on terrorism. The humanity's efforts to eliminate the threat of terrorism led to decades of implementing premature policies of military force, but they were found ineffective and resulted in the spread of extreme threat of suicide terrorism. For prevention of suicide terrorism, the efforts must be made to dismantle the basis of suicide attacks through addressing religious alienation and antipathy against a civilization using the notions similar to treatment of pathology considering psychological motives of suicide terrorists.
