The growth in services has focused issues of service quality both for commercial enterprises and across a range of public services and government institutions. The education sector, in particular, has undergone radical change to meet the needs of its varied constituents. This paper examines key issues in internal service, customer satisfaction, service quality, relational commitment as they apply in one particular education sector. The purpose of this study is to analyze effect of internal service on customer satisfaction, educational service quality. First, In the dimension of internal service, many factors affect internal customer's evaluation for overall satisfaction. They are categorized as five factors; tangibles, reliability, responsiveness, assurance, empathy. The results of this study supported the proposed conceptual framework overall. Therefore, we identified that internal service quality is the antecedent of an internal customer satisfaction, and the consequent variables of an internal customer satisfaction are educational service quality, external customer satisfaction. The major findings of this study are summarized as follows. First, some factors(tangibles, reliability, responsiveness, assurance, empathy) affected positively internal customer satisfaction. Second, external service quality affected positively educational service quality, external satisfaction. In other words, the more internal customers have experienced internal service, the higher internal service quality deliver educational service quality.

Many systems rely on reliable timestamps to determine the time of a particular action or event. This is especially true in digital investigations where investigators are attempting to determine when a suspect actually committed an action. The challenge, however, is that objects are not updated at the exact moment that an event occurs, but within some time-span after the actual event. In this work we define a simple model of digital systems with objects that have associated timestamps. The model is used to predict object update patterns for objects with associated timestamps, and make predictions about these update time-spans. Through empirical studies of digital systems, we show that timestamp update patterns are not instantaneous. We then provide a method for calculating the distribution of timestamp updates on a particular system to determine more accurate action instance times.

A number of studies in recent years of have begun to look at the connection between country affinity (an interest in and admiration of a particular country) and a desire to buy the products and services of that country. Country affinity has been shown to be particularly important when consumers lack other sources of information about a good or service. However, except for direct questioning, methods to identify the affinity consumers might have for another country are lacking. This study examines the degree to which attending a movie set in a particular country will be related to an affinity for that country and possibly by extension the goods and services of that country. It is not the goal of this study to suggest that movies create the affinity, but rather that that the affinity will exist for viewers of the films. Two films set in Ireland and featuring Irish actors where shown to audiences composed of Korean students and a small number of Korean adults. As a point of comparison, students in two introductory consumer classes were also asked to complete a similar questionnaire. Four affinity factors were identified from a list of 17 items. Those who attended the historical drama showed a greater affinity for Ireland than those who attended the romantic musical. Affinity for Ireland among Koreans was also meaningful in predicting interest in purchasing Irish products.

The aim of this study on the Munich Olympic Park is to understand the characteristics and design techniques of the environmental design of G$\ddot{u}$nther Behnisch's architecture. This particular work is chosen because it represents a turning point in his architectural life in terms of his approach to environmental design. The goal of this paper is to research Behnisch's design techniques in order to realiz a way to apply nature-friendly design in contemporary-architecture. In Behnisch's architectural works, the organic design philosophies of Hugo H$\ddot{a}$ring and Hans Scharoun are clealy echoed. The site and natural surroundings are always important in his architecture. In terms of his environmentally-friendly approach, Behnisch's architecture can be defined as one which espresses a harmony between architecture and the naturale-surroundings. In terms of the structural aspect, Behnisch's architectural forms are not imposing, but rather waiting to be discovered naturally. In terms of spatial characteristics, Behnisch's spaces are based on organic characteristics and have a strong relationship between the outside and inside. In particular, the artificial architectural landscape in the Munich Olympic Park through cable-construction connects perfectly with nature.

In many applications of inverter system, it is desirable to obtain an AC output voltage with variable frequency and amplitude. For the variable-speed AC motor drive, the system is one major area of application for the variable-frequency inverter. V ariable~voltage variable-frequency sinusoidal output in three-phase inverter is possible by employing the techniques developed. In this paper, the technique of particular harmonics elimination(PHE) in three-phase PWM inverter-output waveforms is introduced. The required switching patterns are determind on personal computer. Results are stored in look-up table in EPROM and used to control the switching of the inverter devices. The experimental results indicate that the loss in an induction motor is minimized to a degree by using this algorithm. The proposed PWM pattern is effective not only to the induction motor but also to the other electromagnetic machine such as Voltage Regulator, UPS.

Various ceremonial flags were of great importance to the rulers who wished to have the absolute authorities for governing the people. Perhaps nothing indicated the ideas, thoughts and symbols of a certain period and people than the ceremonial flags. The ceremonial flags used in the old China and Korea took the shapes of the heaven and the earth, representing the social backgrounds and thoughts. This study was limited only to the discussion of the heaven-shaped patterns of the ceremonial flags. The 28 constellations of the heaven, in the Oriental way of thinking, were considered to express the immortal powers of Providence and the political domination of the earth. Hence the Polaris, the center of the heaven, symbolized the whole family of king, prince, child born of a concubine and royal harem. Among the constellation pictures were those of Han period, wall painting of old tombs in Koguryeo kingdom and old Japanese kingdom. Referring to the Emperor's ceremonial flags in Daemyeongjibyei, symbolic meanings changed historically and the complete systems of the ceremonial flags were established in Song period when the divine person was drawn on the flags. Animals concerned properly with the particular star and the shapes of the star were both drawn on the flags in Won period and only the shapes of the particular star in Myeong period. In the Imperial enthronement of Kojong the ceremonial flags might be made by the examples of those of Myeong period and remains are now found at Changdeok Palace, which need a further study because the references in detail are not available.

The evaluation of pressure fields acting on slender structures under wind loads is currently performed in experimental aerodynamic tests. For wind-sensitive structures, in fact, the knowledge of global and local wind actions is crucial for design purpose. This paper considers a particular slender structure under wind excitation, representative of most common high-rise buildings, whose experimental wind field on in-scale model was measured in the CRIACIV boundary-layer wind tunnel (University of Florence) for several angles of attack of the wind. It is shown that an efficient reduced model to represent structural response can be obtained by coupling the classical structural modal projection with the so called blowing modes projection, obtained by decomposing the covariance or power spectral density (PSD) wind tensors. In particular, the elaboration of experimental data shows that the first few blowing modes can effectively represent the wind-field when eigenvectors of the PSD tensor are used, while a significantly larger number of blowing modes is required when the covariance wind tensor is used to decompose the wind field.

All the loads in the real world are dynamic loads and it is well known that structural optimization under dynamic loads is very difficult. Thus the dynamic loads are often transformed to the static loads using dynamic factors. However, due to the difference of load characters, there can be considerable differences between the results from static and dynamic analyses. When the natural frequency of a structure is high, the dynamic analysis result is similar to that of static analysis due to the small inertia effect on the behavior of the structure. However, if the natural frequency is low, the inertia effect should not be ignored. Then, the behavior of the dynamic system is different from that of the static system. The difference of the two cases can be explained from the relationship between the homogeneous and the particular solutions of the differential equation that governs the behavior of the structure. Through various examples, the difference between the dynamic analysis and the static analysis are shown. Also the optimization results considering dynamic loads are compared with static loads.

Recently, the number of camera companies that produce commercializing interchangeable lens systems such as digital single lens reflex (DSLR) and compact system camera (CSC) lenses has been gradually increasing. These interchangeable lenses have various kinds of lenses with distinct specifications. In particular, the distance window among these specifications is the function most preferred by customers. Mechanical manual zoom and manual focus in these high end camera lenses with a distance window are in particular desirable specifications and are required for product quality. However, the AF lens group is linked to the zoom cam and moves. Because the AF lens group moves along with the object distance, we can not realize the distance window with only zoom locus calculation. In this paper, in order to solve the problem, we suggest an optical calculation method for a corrected AF zoom cam for an interchangeable lens with a distance window to achieve product differentiation and analyze the error in the calculation.

A theoretical analysis of strong double dips in the amplitude patterns of electromagnetic field scattered by an air cavity embedded in a dielectric medium is presented with the experimental and the numerical simulation. The strongest double dips occur at the locations corresponding to the top and the bottom of the cavity by adjusting the excitation wavelength nearly equal to its radius. In particular, it may be shown that these double dips always become two nulls at a particular sending frequency in the near-field region. The locus of the frequency providing the strongest dip as a function of the observation distance is plotted.
