This study is a descriptive research to establish a positioning strategy of nursing service image, making a perception map on each hospital's nursing service image and ranking construct factors of nursing service image. The results in this study were as follows; 1. The rank of construct factors of nursing service image which were thought important by subjects was the first 'Kindness', the second 'Reliability', the third 'Professional Knowledge', the fourth 'Responsibility', and the fifth 'Advanced Nursing Skill'. 2. The perception map for nursing service image on each hospital showed a hierarchial structure and positioned the first B hospital, the second C hospital, the third D hospital, the fourth A hospital, and the fifth E hospital. The perception map for construct factors of nursing service image and hospitals showed the first dimension : 'Reliability', the second dimension : Kindness', the third dimension : 'Mission', 'Accuracy', 'Neat Appearance', and 'Ethical Aspect', and the fourth dimension : 'Client Advocate', 'Humanistic Consideration', 'Professional Knowledge', 'Responsibility', and 'Advanced Nursing Skill'. 3. The findings of subject's characteristics which affected degree of likeness on each hospital nursing service image to make a marketing strategy were as follows : In A hospital D hospital, and E hospital, the subject group whose hospital dates were under 1 week, education level was upper graduate university, and age was between 40's and 50's, were appeared to have low nursing service image on following construct factors : 'Kindness', 'Reliability', 'Responsibility', 'Mission', 'Neat Appearance', and 'Humanistic Consideration'. In B hospital and C hospital the subject group whose hospital dates were under 1 week or over 5 weeks, sex was woman, and age was 20' s or 40's, having a admission experience on subject hospitals, were appeared to have low nursing service image on following construct factors : 'Professional Knowledge', 'Advanced Nursing Skill', 'Ethical Aspect', and 'Humanistic Consideration'. As the based on above results, nursing managers can use positioning method to develope a marketing strategy for nursing service image.

This study aims to examine the differences in impression formation according to the accessories and hairstyles worn by men, and to investigate the relation between men's appearance and occupation inferences. The subjects were 320 female university students residing in the Seoul metropolitan area. First, wearing eyeglasses gave an impression of more intelligent image and less mild image. It was evaluated that the men wearing neckties have a high dimension of intelligence, and men wearing no necktie have a high dimension of progressiveness. Men with classic hairstyles had a high dimension of intelligence, while men with sports hairstyles had a high dimension of progressiveness, conspicuousness, and attractiveness. Second, metal rims on glasses had a high dimension of empowerment and attractiveness when a red necktie was worn, while horn-rimmed glasses with no necktie had a high dimension of conspicuousness and progressiveness. The men with sports hairstyles, with no eyeglasses had the highest dimension of progressiveness when a red necktie was worn. Third, it was evaluated that wearing a cloche hat or baseball cap had a low dimension of empowerment, while wearing a necklace had a high dimension of empowerment, conspicuousness, and progressiveness. Fourth, the men who wore a suit, eyeglasses, and a necktie with a classic hairstyle were deduced to be professionals, with high-ranking or white-collar jobs. It was found that when men wore a suit with a sports hairstyle, no eyeglasses, and no ties, they were inferred to be engaged in a service job. The baseball caps were strongly associated with technical or simple labor job.

The Snyder's synthetic unit hydrograph method is selected to apply the concept of the fractal dimension by stream order for the practicable rainfall-runoff generation, and fourth types of the Snyder's relation are derived from topographic and observed unit hydrograph data of twenty-nine basins. As a result of the analysis of twenty-nine basins and the verification of two basins, the Snyder's relation which considers the fractal dimension of the stream length and uses calculated unit hydrograph data shows the best result. The concept of the fractal dimension by stream order is applied to the Snyder's synthetic unit hydrograph method. The topographic factors, used in the Snyder's synthetic unit hydrograph method, which have a property of the stream length like $L_{ma}$ (mainstream length) and $L_{ca}$ (length along the mainstream to a point nearest the watershed centroid) were considered. In order to simplify the fractal property of stream length, it is supposed that $L_{ma}$ has not the fractal dimension and the stream length between $L_{ma}$ and ($L_{ma}\;-\;L_{ca}$) has the fractal dimension of 1.027. From the utilization of this supposition, a new Snyder's relation which consider the fractal dimension of the stream length occurred by the map scale used was finally suggested.

Given a domain X and a collection H of functions h : X → {0, 1}, the Vapnik-Chervonenkis (VC) dimension of H measures its complexity in an appropriate sense. In particular, the fundamental theorem of statistical learning says that a hypothesis class with finite VC-dimension is PAC learnable. Recent work by Fitzpatrick, Wyman, the fourth and seventh named authors studied the VC-dimension of a natural family of functions ℋ'²_t(E) : 𝔽²_q → {0, 1}, corresponding to indicator functions of circles centered at points in a subset E ⊆ 𝔽²_q. They showed that when |E| is large enough, the VC-dimension of ℋ'²_t(E) is the same as in the case that E = 𝔽²_q. We study a related hypothesis class, ℋ^d_t(E), corresponding to intersections of spheres in 𝔽^d_q, and ask how large E ⊆ 𝔽^d_q needs to be to ensure the maximum possible VC-dimension. We resolve this problem in all dimensions, proving that whenever |E| ≥ C_dq^d-1/(d-1) for d ≥ 3, the VC-dimension of ℋ^d_t(E) is as large as possible. We get a slightly stronger result if d = 3: this result holds as long as |E| ≥ C_3q^7/3. Furthermore, when d = 2 the result holds when |E| ≥ C_2q^7/4.

In the field of design and manufacturing, there are many problems with managing dynamic states of three-dimensional (3D) objects. In order to solve these problems, the four-dimensional (4D) mesh model and its modeling system have been proposed. The 4D mesh model is defined as a 4D object model that is bounded by tetrahedral cells, and can represent spatio-temporal changes of a 3D object continuously. The 4D mesh model helps to solve dynamic problems of 3D models as geometric problems. However, the construction of the 4D mesh model is limited on the time-series 3D voxel data based method. This method is memory-hogging and requires much computing time. In this research, we propose a new method of constructing the 4D mesh model that derives from the 3D mesh model with continuous rigid body movement. This method is realized by making a swept shape of a 3D mesh model in the fourth dimension and its tetrahedralization. Here, the rigid body movement is a screwed movement, which is a combination of translational and rotational movement.

This study is the bending analysis of rectangular plates with 4-sides simply supported by Finite Element Method using substructuring technique. In finite element method, as the more number of finite element, the more dimension of matrix, it is difficult to obtain accuracy solution. In this paper substructuring technique is applied to finite element method in order to reduce the dimension of matrix according to the number of finite element mesh. To validate finite element method using substructuring technique, deflections and moments of rectangular plates by that method is compared with those of references. Considering the symmetry of the plate and load, one fourth of plate is analyzed. Operating time and the error of solutions according to the number of finite element mesh and substructure are compared with each other.

Considering the above points, this study has been conducted to find out the effects brought by perceived organizational justice towards organizational citizenship behavior, with focus on multi-dimension and multi-class nature of trust. With this objective, I researched the following. First, which type gives larger effect to organizational citizenship behavior, the type of distributive justice (that is lower dimension of organizational justice) or that of procedural justice. Second, what effects are given to the 5 types of trust, by distributive justice and procedural justice. Also, what effects are given to organizational citizenship behavior by the 5 types of trust. Third, which type of justice gives larger effect to organizational citizenship behavior when trust is served as a medium. Fourth, which items should be dealt in priority to lead members of organization towards a desirable direction. The research for this purpose was conducted on the basis of comprehensive analysis of variable including. socio-population variable.

The main purpose of this study is to analyze the reform of deadministration of universities in China by the Cooper's 4-dimension of education policy theory. Based on the theory, the reform of deadministration was analyzed in four dimensions(normative, structural, constituent, and technical dimension). First, in the normative dimension, the Chinese university deadministration policy is fully guaranteed by law, and mainly aimed at "modernization of education management system and management ability". Second, in the structural dimension, a highly administrative management paradigm of universities has played an important role during the early stages of higher education development, but it now becomes one of the main obstacle to its further development. However, the Chinese university de-administration policy is a policy that has taken almost 60 years. Therefore, this problem must be solved step by step. Third, in the constituent dimension, although there were some differences in the attitudes towards "the administration" and "the de-administration" of Chinese scholars, university presidents and the public(students), most of them agreed on eliminating "the administration of universities." Fourth, in the technical dimension, Chinese central government and many universities have accumulated many achievements of "the deadministration policies" in management and practice, while some criticisms are heard, either. However, I hope that all reform cases, regardless of their success or failure, will become a model for future administrative reforms.

The purpose of this survey study is to analyse the playground dimension of elementary school. To complete this mission, it is necessary to drive out elementary school have a lower dimension standard of playground through literal survey. Then, questionnaire and observation survey have been performed to teachers majored in physical education and these are focused on playground dimensions. The field survey study will provide the basic data for calculating proper playground dimensions and design source for planning space program of the school. The result of this survey study are as follows ; First, The Area of 'Gyo-ghi' is decreasing, and the land area of being used for 'Gyo-sa' is increasing. So the area of playground is decreasing. Second, The respondents require a playground size enough to contain 100m running track for testing the physical ability of students. But it is not possible to do so in current domestic condition, it is necessary to revise of the standard of physical test or enact a new one. Third, to solve the problems deviating from the playground size, the respondent suggests that set up a new gym or variable-size playgrounds rather than a large one Fourth, because playground has so much functions as rest, playing, walking and jogging etc besides physical education, it is necessary to consider the spaces for rest and play, when plan a tower-type school or small school.
