The concept of stress wave was introduced through the quantized kinetic energy which is related to the potentional energy change of atom, molecular bond energy. Differentiated molecular bond energy $\varphi$() by the lst order displacement u becomes force F(F = d$\varphi$($u_i$)/du), if resversely stated, causing physically atomic displacement $u_i$. Such physical phenomena lead stress(force/area of applied force) can be expressed by wave equation of linearly quantized physical property. Through the stress wave concept, formation of dislocation, which could not explained easily from a theory of continuum mechanics, can be explained. Moreover, this linearly quantized stress wave equation with a stress concept for grains in a crystalline solid was applied to three typical metallic microstructures and a simple shape. The result appears to be a product from well treated equations of a quantized stress wave. From this result, it can be expected to answer the reason why the defect free and very fine diameters of long crystalline shapes exhibit ideal tensile strength of materials.

Precise concept analysis has been neglected be-cause of a lack of understanding of its necessity and a lack of conceptual analytic knowledge. Concept analysis is the mental work of examining parts, phenomenon and the interrelated whole of a thing. Focus in this article is to extract the critical attributes of hardiness and make an operational delinition. The process of concept analysis is illustrated and documented using the analytic approach described by Walker and Avant (1983). To explore the explicit or implicit meanings of hardiness, existing literature was reviewed. The evolution of hardiness and the dictionary definitions were also added. Hardiness can be defined as follows : A condition of being inured to fatigue or hardship which has three subcomponents-challenge, control and commitment. Critical attributes of hardiness were extracted that may be used in naming the occurrence of the phenomenon. Model case, contrary case, borderline case and related case were described. Antecedents and consequences were explored. The defining critical attributes of hardiness are : 1. Resistance-hardiness involves resistance of stress or hardship. 2. Hardiness involves appraisal of change as a chance. 3. Hardiness implies interpretation of events and self as influential,. 4. Hardiness requires active involving reaction Implications for nursing and for further study are added.

Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention- the prevention of disease and health protection or maintenace, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this studys task was the analysis and definition of the concept of health promotion using Walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well - being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connecteness. Antecedent of health promotion are 1) attaining of a healthy state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.

가상 야외 답사(VFT)는 전통적인 야외 답사의 매력적인 대안으로 간주되지만, 지구과학 교육과정에서 어떻게 가장 효과적으로 활용될 수 있는지는 아직 명확하지 않다. 이 연구에서는 플래시 파노라마 기반 VFT를 활용한 지구과학 수업이 고등학교 학생들의 공간 시각화 능력과 화산 개념 이해에 미치는 영향을 알아보았다. 플래시 파노라마 기반 VFT 활용의 효과를 알아보기 위해 수업 처치 사전 및 사후에 공간 시각화 능력 및 화산 개념 검사를 실시하였으며, 수업 처치 결과를 분석하기 위해 공변량 분석과 선형 회귀 분석을 수행하였다. 연구 결과는 다음과 같다. 첫째, 실험집단의 공간 시각화 능력 향상 정도가 통제 집단에 비해 통계적으로 유의미하게 더 높게 나타났다. 특히, 공간 시각화 능력의 세 가지 하부 범주 중 공간 조작 능력 향상이 가장 큰 것으로 나타났다. 둘째, 대부분의 범주에서 실험 집단의 화산 개념 이해 향상 정도가 통제 집단에 비해 더 높게 나타났으나, 1개 범주를 제외하고 통계적으로 유의미한 차이는 아니었다. 셋째, VFT 활용 후 실험 집단이 통제 집단에 비해 공간 시각화 능력과 화산 개념 이해 간의 상관관계가 현저하게 증가하였다.

End-user Computing(EUC) is one of the significant developments of the 1980s with the explosive supply of personal computers and application software related to it. EUC can be defined as the direct assumption of system development and data processing tasks by the user of the service for his own direct benefit. This is in contrast to the traditional approach to computing in which user requirement are identified and defined and then turned over to professional system designers and programmers for implementation, with the end-user a relatively passive participant in the process. The traditional approach to system development has two obvious drawbacks. First, there is the problem that something may be lost in translation of the problem as originally formulated by the requestor and as it is implemented by the computer specialists. Second, there is the problem that it can take a longtime as growth of significant workloads within system department staff. EUC is an attempt to compensate for this drawbacks associated with the traditional system department process. It permits the end-user to interact directly with an information system, utilizing user friendly software support tools. End-user Searching(EUS) can be defined as accessing online databases and performing search operations for the purpose of finding information to be used by that same person rather than another, in contract with intermediary searcher. The concept of EUS is related to the concept of EUS. That is, two concept are similarly to development background, effects and functions. Therefore, as EUC bring on a change the traditional data processing environment, EUS also bring on a change the traditional intermediary search environment.

A look back at the history of war reveals that leaders/nations which were able to recognize beforehand the change in weaponary or the concept of implementing war achieved victory in war(battle) while those that were not able to do so lost. Along with the development of civilization, so too did the characteristics of war : from the first wave of war (ancient, Napoleon's war)$\rightarrow$ the second wave of war (The first and second World War) $\rightarrow$ to the third wave of war (The Gulf War, and the War in Iraq). Especially notable was the American led victory earned in the Afghanistan and Iraq wars which applied the Rapid Decisive Operations(RDO) concept according to the Effects Based Operations(EBO) following the Gulf War and 9.11. This is the time when methods of warfare is changing through development in military science technology and military innovation and when the change of the defense paradigm including those of the Korea - U.S. alliance is required. We should therefore prepare for the future by delving into the analysis of American Modern warfare and learn from it.
