  • A three-dimensional formulation is proposed to analyze the lateral loading distribution of external actions in high-rise buildings. The method is extended to encompass any combination of bracings, including bracings with open thin-walled cross-sections, which are analyzed in the framework of Timoshenko-Vlasov's theory of sectorial areas. More in detail, the proposed unified approach is a tool for the preliminary stages of structural design. It considers infinitely rigid floors in their own planes, and allows to better understand stress and strain distributions in the different bearing elements if compared to a finite element analysis. Numerical examples, describing the structural response of tall buildings characterized by bracings with different cross-section and height, show the effectiveness and flexibility of the proposed method. The accuracy of the results is investigated by a comparison with finite element solutions, in which the bracings are modelled as three-dimensional structures by means of shell elements.

  • The description of preserved resources is one of the requirements in digital preservation. The description is generally created in the format of metadata records, and those records are combined to generate information packages to support the process of digital preservation. However, current strategies or models of digital preservation may not generate information packages in efficient ways. To overcome these problems, this research proposed an internal structure of information packages in digital preservation. In order to construct the internal structure, this research analyzed existing metadata standards and cataloging rules such as Dublin Core, MARC, and FRBR to extract the core elements of resource description. The extracted elements were categorized according to their semantics and functions, which resulted in three categories of core elements. These categories and core elements were manifested by using RDF syntax in order to be substantially applied to combine metadata records in digital preservation. Although the internal structure is not intended to create metadata records, it is expected to provide an alternative approach to enable combining existing metadata records in the context of digital preservation in a more flexible way.

  • The purposes of this study are to identify service quality elements using Kano's theory, and to examine differences in service quality characteristics among apparel store types. Women over 20 years-old from metropolitan areas in South Korea participated in the study and a quota sampling method was used. The questionnaire was composed of three sections; importance of quality, degree of satisfaction, and demographic factors. Data from 525 questionnaires were used for the statistical analysis. The results were as follows: First, four factors of service quality(sales person, variety of goods, policy, and facilities) were identified. According to Kano's quality elements, sales person was categorized into both one-dimensional quality and must-be quality, and variety of goods, policy, and facilities categorized into attractive quality. Second, sales person, in all store types, was included in one-dimension quality elements and sales person and variety of goods, in local store, were included in attractive quality element. Service policy, in chain store and local store, was included in attractive quality element. Findings of this study provide both industry and academic researchers with a guide to increase customer satisfaction in the store service strategies.

  • Drawing on Herzberg's two-factor theory, this article suggests that visitors to rural tourism base their overall evaluation with an experience on their consideration of two types of aspects referred to as either 'motivators' and 'hygienes' by using the critical incident technique. 233 critical incidents described by 121 participants are categorized into three exclusive factors which are named as experiential factor, cognitive factor, and affective factor. The application of Herzberg's two-factor theory to rural tourism suggests 'satisfiers' to come from the experience-activity itself, experiential factor. While more peripheral elements constitute 'dissatisfiers', cognitive factor. The paper provides the advancement and broad application of Herzberg's theory to further understand rural tourists satisfaction.

  • This study was performed to develop the conceptual framework of the nursing productivity. The study efforts were made (1) to define the concept the nursing productivity, (2) to identify the elements of the productivity, and (3) to determine the relationship among the elements. With the aim, the study employed a descriptive analysis by way of reviewing various references related w the subject. The nursing productivity consists of such elements as the nursing efficiency and Lhe nursing effectiveness which are complememary Lo each other. The nursing efficiency is the quantative input/output ratio, while the nursing effectiveness represents the integrated outcome of sch sub-elements as the degree of accomplishing nursing goals, the quality of nursing service, consumer's satisfaction, and the degree of improvement of nurse's attitude toward the quality care. The nursing prodiccivity can be estimated by summing up the nursing efficiency and the effectiveness. By employing the system theory model, the elements of the nursing producTivity consist of three elements; the input, the process, and the output. By the process elements, the system inputs are transformed to the system outputs nursing efficiency and nursing effecitveness which are input 1.0 the system, in turn, through feedback mechanism(Figure 4).

  • There are eight kinds of formulas for invigorating the liver to cure its asthenic syndrome based on the types of preparation formulas Began-tang, Boganhwan, Bogansan, Bogandan, Boganeum, Boganjoo, Boganjeon and Bogango. Another formula called Bocheonghwan is to invigorate the green colour of liver. There are 22 kinds of Bogan-tang, 12 kinds of Boganhwan, 25 kinds of Bogansan, one kind of Bogandan, one kind of Boganeum, one kind of Boganjoo, one kind of Boganjeon, one kind of Bogango, and two kinds of Bocheonghwan. Combination of herbal medicines, carried out in formulas for invigorating the liver, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Bogan-tang for curing the asthenic syndrome of liver through analyzing the component medicines and combination principles of Hyeongok's Bogan-tang, and furthermore, maximizing the clinical use of Began-tang. This study analyzed the component medicines and combination principles of Hyeongok's Bogan-tang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Began-tang is an odd prescription, composed of 7 kinds of ingredients No.1 Radix Angelicas Sinensis (2don;7.5g), No.2 Rhizoma Chuanxiong (1don;3.75g), No.3 Radii Polygoni Multiflori (1don), No.4 Fructus Lycii (1don), No.5 Cortex Cinnamomi (1don), No.6 Rhizoma Gastrodiae (1don), and No.7 Radix Glycyrrhizae (1don). There are three methods for curing the asthenic syndrome of liver according to the five elements doctrine invigorating the liver, invigorating the kidney and purging the lung. First, if you suffer from the asthenic syndrome of the liver, you need to invigorate your liver. There are two available methods, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each imply the pungent taste and the warm property invigorate the liver. In the case of taste invigoration, two herbal medicines with pungent taste, Radix Angelicas Sinensis and Rhizoma Chuanxiong, are combined into the principal and assistant herbal medicine, respectively. For property invigoration, two herDal medicines with the warm property, Cortex Cinnamomi and Rhizoma Gastrodiae, are combined into adjuvant herbal medicines. Secondly, if you suffer from the asthenic syndrome of the liver, you need to invigorate your kidney which is mother in the mother-child relationship in inter-promotion among the five elements. There are two methods to invigorate the kidney, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each mean the bitter taste and the cold property invigorate the kidney. Therefore, it is important to use bitter herbal medicines for taste invigoration and cold ones for property invigoration. Both Differ and cold herbal medicines, Radix Polygoni Multiflori and Fructus Lycii, are combined into adjuvant herbal medicines. Lastly, if you suffer from the asthenic syndrome of the liver, you need to purge your lung which is an element being surpassed in the relationship between the elements surpassed and ones not surpassed in inter-restraint among the five elements. There are two methods to purge the lung, which include taste and property invigoration according to the theory for properties and tastes of herbal medicines. Taste invigoration means to purge the lung with pungent taste and property invigoration to purge the lung with warm property. Therefore, it is important to use pungent herbal medicines for taste invigoration and warm ones for property invigoration. Both pungent and warm herbal medicines, Radix Angelicas Sinensis and Rhizoma Chuanxiong, were combined to invigorate and purge the lung. In addition, Radix Glycyrrhizae are combined as dispatcher herbal medicine, harmonizing all the herbal medicines composing the formula. First, to cure the asthenic syndrome of the liver, the methods of invigorating the liver and the kidney, and purging the lung should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herDal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Bogan-tangon is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.

  • Paper presents an improved solution algorithm based on Finite Element Method to analyse piled raft foundation. Piles are modelled as beam elements with soil springs. Finite element analysis of raft is based on the classical theory of thick plates resting on Winkler foundation that accounts for the transverse shear deformation of the plate. Four node, isoparametric rectangular elements with three degrees of freedom per node are considered in the development of finite element formulation. Independent bilinear shape functions are assumed for displacement and rotational degrees of freedom. Effect of raft thickness, soil modulus and load pattern on the response is considered. Significant improvement in the settlements and moments in the raft is observed.
