A center of economy, during last 50 years, has been transferred from production into consumption and a new consumption culture has been made by changing from reasonable trend into subjective and psychological trend. In the past, an interest of consumers was to possess things, however, in present, an interest of them is mental value and satisfaction to experience various cultures, to focus value and meaning human's life, and to realize desires. According to this trend, society's interest on interior design has continuously increased. Social phenomenon to make a serious consideration of design management and value is rushing with various brands on the basis of marketing strategy. In this kind of era, interior designers also should try to make interior design area brand through long, objective and systematic marketing plan. Therefore, this research shows differentiation strategy to make interior design brand on the basis of marketing strategy with theoretical background through literature study, and presents an example of spa and cosmetic beauty salon - current new consumption culture - on the basis of marketing strategy.

This thesis sets out to study the immanent mechanism of architecture which had classified as external spaces in general. As human controls a space, it controls or manages human's behavior, too. This study is depended on the humanities to analyze a various operation of power in the architectural space. It makes a comparative study of a space-power in a dwelling space through a discourse of Michel Foucault and Jacques Lacan, in particular everyday's microscopic scope. According to analytical results, the space-power of dwelling falls under the influence of a spacial arrangement and subject's desire. It has shown a noticeable characteristics in aspects production & consumption, using behavior, and use value. As it is seen through the aspects of production & consumption, owns of the space-power in a dwelling could not be its subject. We have also understood about a physicalistic furniture at the using behavior, it has a special power unconsciously to control a human's action and lifestyle. And then in the aspects of use value, the centric theme is a television. It lies on the core of space-power in dwelling, because is profoundly related to an innate respect of a dwelling value. In conclusion, so this study has the important meaning in the side to offer some interpretative possibility about the architectural space-power through a microscopic structure.

Having set a trend for luxury fashion brand markets since the $17^{th}$ century, France has established the norms and the forms of the fashion business. In addition, it has maintained its status as a leading fashion power by discovering economic value from the intangible value of design and brand, and developing fashion into a high value-added industry. This paper aims to examine the socio-cultural factors that have exerted a positive influence on the formation of "fashion power" in France from a historical perspective. It will focus on four major external historical factors that made France the top fashion power: insights and innovation of French leaders as well as their constant concerns and efforts for the promotion of fashion, a tradition of experimental cultures and arts, open and the public-centered social environment and an atmosphere of cherishing the values of creation, and the establishment of a legitimate system that protects them.

The Internet has had a significant impact on the operations of record companies and has transformed the role of music consumers. Active music consumers are regarded as not just consumers but also co-creators and innovators who create value; therefore, firms need to create environments in which they can learn from consumers. Prior studies exist on the effects of the Internet on the music business, including its structure and culture. However, these studies did not focus on exploring how the relationship between record labels and consumers changed, how networked music consumers influence value creation and how record labels are responding, and the difficulties from using and the drawbacks of interactive media and new business models in the music market. This study investigates these issues through interviews.

The Managing and measuring performance have long been a popular topic in business. Traditions of financially-oriented managing and measuring performance have provided managers with relatively objective and scientific results of measuring performance until now. But today the value of organization is influenced more by intangible assets than tangible assets. Nobody thus believes that the performance and the value of organization can be measured by financial indicators only. In this background, numerous researches have been conducted to find alternatives to measuring the value of organization's intangible assets. One of the remarkable achievements would be "Balanced Score Card (BSC), "which covers three sectors of indicators, each from customer relations, internal process innovations, and learning and human resource development, in addition to traditional financial indicators. Unfortunately, even BSC, let alone others, fails to accomodate all performance indicators as a holistic system. Namely, performance measuring techniques including BCS, at present, fail to reflect the dynamic features in their model - i.e., the casual relations and the interactions between the indicators, and there is no way of taking into account the impact of delayed feedback which flows from introduction of new policy and legislative changes, etc. Therefore, this paper attempts to devise a means for adding dynamic features to BSC, by introducing the system dynamics concept, with a focus on the effect of casual relations and feedback structure.

Color rendering index (CRI) and luminous efficacy (LE) are two key performance factors of white LEDs (WLED). While most recent works in optics focus on methodology to improve these factors, little attention has been dedicated to chemical composition of materials. This paper studies the effect of $Sr_{2.4}1F_{2.59}B_{20.03}O_{74.8}:Eu_{0.12},Sm_{0.048}$ phosphor (SrSm), in terms of concentration and particle size on CRI and LE of 8500 K - WLEDs. Importantly, the molar mass of the componential ions in SrSm are calculated to shed light on the connection between the chemical composition of the material of interest and the performance of WLEDs. Results show that CRI can be improved to a value of around 86 by boosting red-light components in WLEDs, for all 3 major configurations: conformal, in-cup, and remote phosphor. CRI value tends to decrease with larger size of particles, while LE value goes in the reverse direction. On the other hand, both CRI and LE appear to be reduced at higher concentration of SrSm. This light attenuation is analyzed by using the Lambert-Beer law and Mie-scattering theory.

Even though algorithm of intrusion detection is superior to other algorithm in intrusion detection system, it is supposed that captured packet happened hostly lead to lose packet in system architecture when a buffer is full. If packet lost concerned to be hacked, it might impact to system all over. In this paper, try to focus on performance improvement of detection system. Buffer with threshold value could classify normal packet and hacked packet. The buffer accept normal packet and supposed to be hacked packet until critical value. When buffer reached at threshold value, destroyed packet is only normal packet. Proposed method can complement weakness that bypass hacked packet.

Tour products have been recognized as a perishable asset. For tour operation companies (TOCs), improving profitability is a core decision problem for their business. Since package tour products, typical products of TOCs, are perishable after the tour was departed, TOCs have been tried to increase their sales before the departure date with various marketing strategies including price discounts. The pricing problem for perishable assets have been studied in Revenue Management for a long time. However, it is hard to find a research on pricing decisions for tour products. In this paper, we focus on a pricing problem for tour products. In particular, we will consider the pricing scheme with customer preference values on purchasing conditions. With conjoint analysis, we can use the part-worth value as a preference value for each level of purchasing conditions. To construct various discount prices, we use an enumeration method and suggest a mathematical optimization model. With experimental analysis for a sample tour package, we will show that our pricing process is very helpful for designing customer-oriented pricing decision.

Recently the water management department advised the water treatment industry to focus on deploy the chemical free and the environmentally responsible process to adopt on water treatment plants in every country. In this objective, water treatment process started using ultrasonic based phycocyanin extraction with fluorescence measurement techniques to detect the change in the yield of phycocyanin. This paper propose the design of optical filter model for fluorescence technique based immersive optical phycocyanin measurement sensor design. The proposed design uses the multi-wavelength sensor module for irradiating part, and this plays a role of removing a wavelength band other than 590 ~ 620 nm. The preliminary study on immersed phycocyanin sensor, the fluorescence value of picocyanin according to the ultrasonic intensity, treatment time and number of cells was measured using JM phycocyanin module to emulate the proposed design, and were compared performance of the proposed sensor emulation. In this design, the phycocyanin fluorescence value increased about 2.1 ~ 4.7 times as the ultrasonic treatment time increased as compared with JM phycocyanin module, and the phycocyanin fluorescence value within the analysis range was obtained by ultrasonic treatment within one minute.
