We have investigated the mixed-state Hall effect in HgBa$_2CaCu_2O_6$, HgBa$_2Ca_2Cu_3O_8$, and Tl$_2Ba_2Cau_2O_8$ thin films as functions of the magnetic field up to 18 T. At high fields and low temperatures, the scaling exponent in ${\rho}_{xy}$ = A${\rho}_{xx}\;^{\beta}$ shows a universal behavior, ${\beta}$ = 1 ${\pm}$ 0.1, regardless of the field, the number of CuO$_2$ layers, the types of defects, and even the types of compounds. At low fields and high temperatures, p = 1 ${\pm}$ 0.1 also appears as a universal number although the observed field range is rather limited. These observations show the universal scaling of Hall resistivity in the regions of the clean and the moderately clean limit, consistent with a theory based on the midgap states in the vortex core.

It is needed that nursing scholars in Korea should understand the philosophy and perspectives of oriental medicine, and then explore the possiblities of theory building which can be a Korean’s unique nursing theory. With the assumption of this kind of work can be achieved by cooperation of oriental medicine and nursing areas, this study measures the subjectivity -opinions, attitudes, and values-of professional from these two areas. Identifing the schemata(structure of subjectivity) would be a basic step for the strategies and construction of oriental nursing theory. The Q-sorts of 57 professionals were combined into five distinctive factors, namely, Q-types. The five factors were named as follows : Type I, Fundamentalist, consistently insists that the understanding of oriental medicine should be a basic step for the development of oriental nursing model, because ororiental medicine's theories and practices in curing are very unique and different from the western. Type Ⅱ, Pessimist, denies the uniqueness of oriental nursing field and its independency, because of lack of scientific evidences and professionalism. Type Ⅲ, Harmonist, believes the basic concepts in two different medic관 spheres are identical, but, at the same time, accept the uniqueness of the two. They try to propose Korean Nursing Model which accomodates local culture and conventions, and the way of Nurturing Life(Yang-sang), based on the traditional western nursing. Type W. Needy Follower, merely expects the Korean Nursing Model which considers the characteristics of Koreas culture and physical constitution and, thus, is more suitable to them. Some-times, they experience the discontent and conflict when they need more qualitative and culture-oriented nursing interventions. Type V, Alternative Giver, actully clarifies the concept of Oriental Nursing, and provides specific program as a alternative of universal western nursing. Various ways of Nurturing Life (mental, life, and diet Yang-sang) were introduced as a guideline for the specification of the nursing area and its con-tent. Throughout the study, the five different Q-factors were identified, and the concept of Oriental Nursing and aspects of its theory construetion were discussed.

The purpose of this study is to propose the clue of planning guideline for the elderly welfare center supporting the healthy life of the elderly through deriving the planning element of the elderly welfare center based on the Salutogenic Model(SM). The research method was proceeded with literature review. The meaning of Sense of Coherence(SOC) and Generalised Resistance Resources(GRR) which constitute Salutogenic Model is established. The correlation between SOC and GRR is analyzed. The conclusions of this study are as follows. First, EBD, BD, HD, UD, and BFD were studied as planning theories that could enhance the SOC of space. Second, based on the five planning theories, 43 planning elements needed for the elderly welfare center plan were derived. Third, as a result of classifying the plan elements based on the SOC, 'Manageability' is divided into 22 elements, 'Meaningfulness' is 11 and 'Comprehensibility' is 10 elements. Fourth, the details of the SOC items for each theory are as follows: BFD focuses on 'Manageability' with 'Manageability'(74%) and 'Comprehensibility'(26%), but 'Meaningfulness' does not exist. And UD regards 'Comprehensibility'(66%) as important, and 'Manageability' and 'Meaningfulness' as 17%. BD, on the other hand, has a high percentage of 'Meaningfulness'(70%), 'Comprehensibility'(21%) and 'Manageability'(9%). Next, the 'Manageability' of HD and EBD is 46%. And HD was 'Meaningfulness'(34%), 'Comprehensibility'(20%), and EBD was 'Meaningfulness'(30%) and 'Comprehensibility'(24%). The three items of SOC showed different distribution according to the spatial planning theory. As a result of the analysis, the spatial planning theory with the 'Comprehensibility' was related to Universal Design(UD), and the spatial planning theory with the 'Manageability' was related to Barrier-Free Design(BFD). In addition, the spatial planning theory of 'Meaningfulness' was related to Bio-philic Design(BD). Therefore, the plan of the elderly welfare center needs to approach the multidimensional design methodology to enhance the SOC(Sense of Coherence).

나흠순의 이기일물론과 인심도심성정설은 장현광의 성리설 형성에 많은 영향을 끼친 것으로 평가되어 왔다. 장현광의 경위설은 리기불상리의 원칙에 충실하다는 점이 두드러지는데, 이는 나흠순의 이기일물설과 일맥상통하는 점이 없지 않다. 그러나 장현광의 이기경위설은 나흠순의 이기일물설과 근본적인 차이가 있다. 첫째, 장현광이 리와 기가 두 가지 존재가 아님을 강조한 것은 사실이지만 그의 이론체계에서 리와 기는 내용적 일치의 관계에 있지 않다. 둘째, 장현광의 철학체계에서 최고 범주는 어디까지나 리라는 점이다. 그의 이기론이 지닌 이러한 특징은 나흠순의 이기설에서 찾아보기 어려운 면모이다. 장현광이 도심을 성, 인심을 정으로 본 것은 나흠순의 인심도심성정설의 영향이 분명하다. 다만 그는 체는 용을 겸할 수 있다는 논리로 도심이 미발뿐만 아니라 이발도 겸한다는 논리를 펼쳤기 때문에 그의 인심도심설이 나흠순의 설의 단순한 답습이라고 하기 어렵다. 더욱이 공과 사를 기준으로 도심과 인심을 구분한 인심도심공사설은 인심과 도심을 모두 이발의 정 층위에서 이해했다는 점에서 나흠순의 인심도심성정설과는 차원을 달리한다. 그렇다면 장현광 성리설의 형성을 어떻게 보아야 할까? 한 마디로 장현광의 철학이론은 호발설을 비판하는 맥락에서 형성되었다고 할 수 있다. 그의 주된 철학적 관심사는 리(사단 도심)와 기(칠정 인심)를 두 근본으로 여기는 학설을 비판하고 리와 기를 하나로 통합하는 철학 체계를 수립하는 것이었다. 결국 리기경위설로 대표되는 그의 성리설은 당시 조선유학계의 학문적 상황에 대한 고민의 산물이었다는 결론이 가능하다.

The purpose of this study was to prepare improved education guideline by grasping parts and items felt difficult to apply instruments by the students of the dental hygiene department in the practice of oral prophylaxis using manikin and analyzing factors influencing the satisfaction at the oral prophylaxis subject. To achieve this purpose, 285 senior students of the dental hygiene department located in the Kwangju. Jeonnam area who took theory and practice courses of oral prophylaxis but only practiced the manikin from the second semester of 1st year were selected as the subjects. The following results were obtained. 1. In the manikin, the most difficult part was maxillary anterior lingual in the use of explorer, sickle scaler, and universal curet, and maxillary right posterior lingual was in the use of gracey curet. In the dentiform, the most difficult item was instrument stroke in the use of explorer, sickle scaler, universal curet and gracey curet. 2. The highest stressor was the lack of knowledge and skill in practice of oral prophylaxis, followed by the lack of confidence, and difference between theory and practice in oral prophylaxis. The overall practice satisfaction was 3.23 at oral prophylaxis. The highest satisfaction was found in patient and operator position(3.51), followed by basic skill(3.34), the way to use hand instrumentation(3.16), and the way to use oral examination instrumentation(3.01). 3. According to school records, satisfaction at oral prophylaxis practice satisfaction was 3.36 of good, 3.24 of fair, and 3.06 of poor, suggesting significant difference(p<0.05). Students who participated just in practice during a school term showed 3.47 of satisfaction. The highest satisfaction was found in a full-time professor as a professor in charge(3.24) and there was significant difference(p<0.05). 4. The highest correlated factor between oral prophylaxis theory and practice satisfaction was curriculum satisfaction. The use of hand instrumentation was found to have the greatest effect on the practice satisfaction at oral prophylaxis, followed by basic skill, the way of basic instrumentation, and position. There was statistically significant difference(p<0.01).

The author previously defined the spectral invariants, denoted by $\rho(H;\;a)$, of a Hamiltonian function H as the mini-max value of the action functional ${\cal{A}}_H$ over the Novikov Floer cycles in the Floer homology class dual to the quantum cohomology class a. The spectrality axiom of the invariant $\rho(H;\;a)$ states that the mini-max value is a critical value of the action functional ${\cal{A}}_H$. The main purpose of the present paper is to prove this axiom for nondegenerate Hamiltonian functions in irrational symplectic manifolds (M, $\omega$). We also prove that the spectral invariant function ${\rho}_a$ : $H\;{\mapsto}\;\rho(H;\;a)$ can be pushed down to a continuous function defined on the universal (${\acute{e}}tale$) covering space $\widetilde{HAM}$(M, $\omega$) of the group Ham((M, $\omega$) of Hamiltonian diffeomorphisms on general (M, $\omega$). For a certain generic homotopy, which we call a Cerf homotopy ${\cal{H}}\;=\;\{H^s\}_{0{\leq}s{\leq}1}$ of Hamiltonians, the function ${\rho}_a\;{\circ}\;{\cal{H}}$ : $s\;{\mapsto}\;{\rho}(H^s;\;a)$ is piecewise smooth away from a countable subset of [0, 1] for each non-zero quantum cohomology class a. The proof of this nondegenerate spectrality relies on several new ingredients in the chain level Floer theory, which have their own independent interest: a structure theorem on the Cerf bifurcation diagram of the critical values of the action functionals associated to a generic one-parameter family of Hamiltonian functions, a general structure theorem and the handle sliding lemma of Novikov Floer cycles over such a family and a family version of new transversality statements involving the Floer chain map, and many others. We call this chain level Floer theory as a whole the Floer mini-max theory.

Today the company's brand sites are in tendency locating as a handy method to administrate company vision, value and image. So this study tried to examine the aspects of storytelling around Amore Pacific's brand site. To secure the discussion's centrality and concreteness, two issues are considered to be aimed in methodology. First, the menus of relevant site were examined to see if they are securing minimal narrative. This was an attempt to discuss the minimum narrativity that target text is supposed to possess, to objectify little more the term 'storytelling.' After considering the menus of relevant site through narratological ideas of Gerald Prince, the menus that satisfy the level of minimum narrative were hardly seen. Even 'OUR STORY', showing the intention of unraveling the vision and values within the company brand by stories, is not seemed to be reaching universal, objective storytelling. Second, pragmatic, reception theory were applied as another standard to judge storytelling possibilities of Amore Pacific's brand site. Roger C. Schank's script theory, being considered in the field of cognitive linguistics and cognitive psychology, became a handy tool for examining the interactions and its meaning between brand sites and its visitors. As a result, the relevant site could be seen as attempting storytelling following time sequence, through narrator kindly explaining 'visual image-event.' And it was conjecturable that, because of such function of narrator, visitors finishes storytelling in a personal shape by operating internal story based script. This study examined the level and methods of storytelling limited in online environment called as company brand site. But more studies are needed to be in progress, such as about the ways for company websites or brand sites to have an effective, continuous influence on potential consumers, narrator set-up ways suitable for character of subordinate menus, organizations of minimum narrative and so on.

Geometric abstract art has been a persistent form since ancient times and is defined in modernity as a genre of abstract painting. According to previous studies, the geo- metric structure of traditional Korean costume possesses uniqueness based on Korean thought and philosophy. Therefore, the purpose of this study is to first derive the characteristics of Wilhelm Worringer's theory, a theorist of geometric abstraction, and then compare the spiritual similarities between the traditional Korean costume and geometric abstract art, with the aim of examining the artistic competitiveness of Hanbok. Photographic materials from domestic and international museums, as well as books published by museums and government agencies, were analyzed. Further, the characteristics of Worringer's theory of the abstract impulse were derived. The results are as follows. First, the external factors are characterized by a single geometric shape on a flat surface with restrained spatial expression. The internal factors include anxiety, comfort from religion or ideology, and the need for a visual refuge for rest. Second, traditional Korean costume and geometric abstraction share common spiritual contexts of artistry, transcendence, and stability according to Worringer's theory. Third, the study of the spiritual similarities between the traditional Korean costume and geometric abstract art through Worringer's theory reveals that the artistry of traditional Korean costume is expressed in universal forms, transcendence as intrinsic origins, and stability as a unique aesthetic consciousness. These findings provide a framework for reinterpreting the originality and universality of traditional Korean costume as Korean cultural content, infused with the characteristics of modern art.

Utilizing artificial noise (AN) is a good means to guarantee security against eavesdropping in a multi-inputmulti-output system, where the AN is designed to lie in the null space of the legitimate receiver's channel direction information (CDI). However, imperfect CDI will lead to noise leakage at the legitimate receiver and cause significant loss in the achievable secrecy rate. In this paper, we consider a delayed feedback system, and investigate the impact of delayed CDI on security by using a transmit beamforming and AN scheme. By exploiting the Gauss-Markov fading spectrum to model the feedback delay, we derive a closed-form expression of the upper bound on the secrecy rate loss, where $N_t$ = 2. For a moderate number of antennas where $N_t$ > 2, two special cases, based on the first-order statistics of the noise leakage and large number theory, are explored to approximate the respective upper bounds. In addition, to maintain a constant signal-to-interferenceplus-noise ratio degradation, we analyze the corresponding delay constraint. Furthermore, based on the obtained closed-form expression of the lower bound on the achievable secrecy rate, we investigate an optimal power allocation strategy between the information signal and the AN. The analytical and numerical results obtained based on first-order statistics can be regarded as a good approximation of the capacity that can be achieved at the legitimate receiver with a certain number of antennas, $N_t$. In addition, for a given delay, we show that optimal power allocation is not sensitive to the number of antennas in a high signal-to-noise ratio regime. The simulation results further indicate that the achievable secrecy rate with optimal power allocation can be improved significantly as compared to that with fixed power allocation. In addition, as the delay increases, the ratio of power allocated to the AN should be decreased to reduce the secrecy rate degradation.
