The Korean peninsular is a typical mountainous terrain country which has 75% of mountains with having featuring of east-high west-low and north-high south-low type. Though the physiographic feature is not changed, the future operational environment has been frequently changed through artificial transformation by people living in the city. While Korea has been changed continuously since 2000, 90% of Korean territory has been urbanized and the majority of people live in the city. In particular, in the case of combat in urban area, there might be lots of limitations because of confusing with millions of people and complex buildings. The combat commanders should make an effort to overcome such difficulties through detailed IPB(Intelligence preparation in the battlefield) considering various situation before planning for major operations. They should change warfighting concept and paradigm. This paper finds the normal characteristics of urban operation and physical traits of the Korean peninsular. As the urbanization has been accelerating in Korea, practical implications about how to prepare the urban operation are discussed.

Entrepreneurship is vital in the foodservice industry more than any other industry as a force to overcome the obstacles in the management environment due to the relatively small scale of the business. The existing literature shows that entrepreneurship not only leads toward innovative management, but also enhances corporate performance. This paper undertakes an analysis of the relations between entrepreneurs' needs for achievement and entrepreneurship, and the way in which entrepreneurship influences corporate performance. For this study, 250 restaurant owners in Busan were surveyed from December 10 to 20, 2008, and 232 copies of the questionnaire were analyzed. SPSS 12.0 package program and Amos 5.0 were used for statistical analysis. The result of the analysis suggests that entrepreneurs' desire to achieve goals could influence the entrepreneurship variable. Moreover, entrepreneurship enhances corporate performance. In sum, the three-dimensional scale of entrepreneurship which includes innovativeness, constructive risk taking, and proactiveness strengthens corporate performance. Future research should investigate the processes by which entrepreneurship enhances performance and other potential moderator variables.

Conventional treatments of war diffusion focus extensively on dyadic relationships, whose impact is thought to be immutable over the course of the conf lict. This study indicates that such conceptions are at best incomplete, and more likely misleading to explain the spatial diffusion of wars. Using social network analysis, we examine war joining behavior during World War I. By employing social network analysis, we attempted to overcome the dichotomous understanding of geography as space and network in the discipline of conflict studies. Empirically, networked structural elements of state relationships (e.g., rivalry, alliances) have explanatory and predictive value that must be included alongside dyadic considerations in analyzing war joining behavior. In addition, our analysis demonstrates that the diffusion of conflict involves different driving forces over time.

The final purpose of driveability analysis is to confirm whether a selected hammer drives a pile to a desired penetration depth and/or capacity without damage. The capacities from static analysis methods are meaningless if the pile cannot be driven to the required design depth and the ultimate capacity without damage. It often occurs that there are big differences between the capacities from measurements and calculations. It may be because the driveability is not evaluated due to the lack of engineers' understanding of the driveability of pile driving. The engineers in the field sometimes assume simply the penetration depth with standard penetration value only. In this study some test pilings with dynamic pile loading tests were performed to give an understanding about the driveability. The influence factors(driving resistance, impedance, material strength, hammer) on the driveability of steel piles were analysed with the monitoring data obtained from the dynamic load tests. It was shown that more cost-effective design can be made in case the driveability analysis and high strength steel pile are appropriately adopted in the design.

For operation of IEEE 802.22 WRAN system, spectrum sensing is a essential function. However, due to strict sensing requirement of WRAN system, spectrum sensing process of CR nodes require long quiet period. In addition, CR nodes sometimes fail to detect licensed users due to shadowing effect of wireless communication environment. To overcome this problem, CR nodes collaborate with each other for increasing the sensing reliability or mitigating the sensitivity requirement. A general approach for decision fusion, the "k out of N" rule is often taken as the decision fusion rule for its simplicity. However, since k out of N rules can not achieve better performance than the highest SNR node when SNR is largely different among CR nodes, the local SNR of each node should be considered to achieve better performance. In this paper, we propose two novel data fusion methods by utilizing confidence vector which represents the confidence level of individual sensing result. The simulation results show that the proposed schemes improve the signal detection performance than the conventional data fusion algorithms.

Recently, due to construction of the recession quantity of unsold houses is increasing and construction company is experiencing financial difficulties. As a result, construction is being ousted, or workout. Accordingly, construction may be devising a method for oneself like salary cuts, layoffs as part of the rationalization of management. But in this way may be increasing employees's perception about job insecurity and payment unsatisfaction. This has the potential to do employees turnover. Turnover has be known that it brings both positive and negative results to the organization. But if new employees leaves early, the positive aspect of the organization will be less likely. In order to solve these problems, new employees turnover intention will be necessary for the thorough management. The purpose of this study is to identity how the perception of job insecurity, payment satisfaction, organizational commitment, excessive workload, competitiveness for employment and job suitability affect new employees turnover intention. As the degrees of impacts of variables affecting turnover intention of new employees might be different between small to medium and large construction companies, this research also compares the differences between these two groups and suggest measures for reducing turnover intention.

In order to overcome the limitations of the previous study, this study reviews the concepts related to spirituality, spiritual wellbeing, workplace spirituality, spirituality and religion in detail. Furthermore, this study was to examine the effects of spiritual education. It is important to examine the effects of spiritual education on individual performance. To do this, proposed model in this study reflects individual, group, and organizational perspectives to reflect all dimensions of spirituality. The proposal model rooted in the theory of vocational personality types and work environments was analyzed empirically. We found that non-work commitment has a negative effect on perceived importance of spiritual education. On the other hand, the appropriateness of work and managers' concerns have a positive effect on the awareness of spiritual education. In addition, awareness of spiritual education has a positive influence on satisfaction of spiritual education. Finally, perceived importance of spiritual education has a positive effect on the satisfaction of spiritual education. Conclusions and implications are discussed.

1970년대 이후 도시 중심의 급속한 공업화 정책을 추진한 결과, 농촌의 저발전 문제에 직면하고 있다. 1980년대 중반부터 이에 대한 대응전략으로서 농공단지 개발을 통한 산업유치, 농산물 가공산업 개발 및 유통체계 개선, 관광농업 개발 등이 논의되어 왔다. 오늘날에 와서는 WTO 체제 하에서 농산물 무역자유화가 보편적인 규범으로 자리잡아 가면서 이러한 변화를 더욱 재촉하고 있다. 이 글의 목적은 농공단지와 관광농원을 중심으로 우리 나라 농산업 발전과정을 고찰하고, 향후 발전 방향을 제시하는 데 있다. 농공단지와 관광농원 육성사업의 특성과 성패요인을 분석하는 데 있어서 이용된 자료는 주로 2차자료이다. 농공단지조성사업의 성과에 대한 많은 논란에도 불구하고, 개량적인 지표는 그것이 농촌지역경제 활성화에 직간접적으로 공헌하였음을 보여준다. 농촌노동력의 66.1%를 고용하고, 이들에게 1인당 월 평균 70만원 이상의 소득을 제공해 주었으며, 서비스업 등 관련산업의 성장에도 영향을 미쳤기 때문이다. 그러나 농공단지조성사업은 많은 문제점도 안고 있다. 농촌지역에 숙련 노동자가 부족하며 직업훈련 기회 및 창업지원 프로그램이 도시지역에 집중되어 있다. 또한 입주 기업이 농산물이나 골재 등 현지 자원을 활용하는 경우가 매우 적은 것으로 나타나고 있다. 이에 대한 대응책으로서 농촌 주민들이 손쉽게 참여할 수 있는 직업훈련 프로그램을 개발하여 제공해야 하며, 경영과 시장정보 분석 등을 기술적으로 지원할 수 있는 효과적인 지도체계를 구축해야 한다. 관광농업은 새롭게 떠오르는 산업이다. 아직 기반이 취약하지만 국가 경제성장과 도시화 진행 추이에 비추어 볼 때 관광농원은 점차 증가할 것으로 전망된다. 하지만 이 산업의 지속적인 발전을 위해서는 정책의 유연성을 확보해야 하고, 농원운영자의 경영능력이 향상되어야 하며, 수요의 계절성을 극복해야 하는 등의 과제를 안고 있다. 또한 공동운영 형태의 농원에 있어서는 참여자들을 효과적으로 조직하고, 토지소유권 분쟁을 해소해야 하는 문제가 있다. 무엇보다도 아직 이 산업의 기반이 취약하다는 전제 위에 점진적이고 지속적인 재정과 기술지원이 요청되고 있다. 다양한 운영 프로그램의 개발과 지역내 네트웍 형태의 연계개발 방식의 채택이 필요하며, 관광농원이나 농어촌휴양지 개발지역에서는 산업개발 및 주거지 개발계획이 관광여건 조성과 총체적으로 연계되어야 할 것이다.

Entrepreneurship and innovation are highlighted as a way to overcome limitations and risk factors caused by today's uncertain business environment. As the uncertainty in the business environment increases, organizations are required to adapt to ever changing business dynamics. For this adaptation, entrepreneurship and innovation are crucial factors. This study proposes a model to explain a structural relationship between entrepreneurship, technological innovation, and innovation performance. The unit of analysis focus is small and medium-sized businesses. Empirical results show that there are positive causal relationships from entrepreneurship to technological innovation, and from technological innovation to innovation performance. Additionally, no direct relationship from entrepreneurship to innovation performance can be achieved through innovation activities such as technological innovation. This study points out the importance of entrepreneurship and technological innovation, and suggests that entrepreneurship along with technological innovation should be internalized as business practices leading to increased performance.

This article is a study on modern wall painting of Korea. The system of wall paintings in Korea is studied in the first chapter. It contains the function, the painters'peculiar character, the psychological basis and the subjects of wall painting. The most popular subjects are the Lee dynasty's folk custom and visual symbols of this period. The second chapter sees the study of these subjects in Lacan's psychoanalytic view. The representation of Lee dynasts custom in this post modern society reveal that the Korean lives in the realm of the imaginary in visual level. That is the projection of their desire to be in the perfect community which is believed to be existed in Lee's dynasty. However the visual circumstance in Korea is the symbolic which is constructed of the Western symbols. This visual confliction reveals Korean Habitus and the lack of independent visual expression method. For conclusion, it is proposed that the relation of Korean Habitus and design must be studied to create proper visual circumstance.
