This study presents the strategic directions for Korean multi-brand fashion stores by running in-depth industry research and market analysis. Over 20 professionals were selected from Korean multi-brand fashion stores for this study and in-depth interviews were conducted to evaluate related subjects. The results of the study were as follows. First, Korean multi-brand fashion stores could be classified into three criteria: operating ownership, merchandise mix, and store identity. Second, operating ownership criterion was chosen for further investigations of strategies and directions of the multi-brand fashion stores. The operating ownership criterion consists of three types; department store types, specialty store types, and boutique types. Each type deploys different buying practice, organizational strategies, and distribution channels. Lastly, the suggested strategic directions for each type are summarized as follows. The 'department store type' should utilize its strong direct buying capabilities and acquisition of merchandising can be more effectively managed. The store should utilize its strong buying power as a tool to develop new private brands (PBs). For 'specialty store type', two key factors have been derived: market share expansion and positioning themselves to become a new distribution channel. To respond to these factors, the store needs to be perceived as a brand then diversify its business. Strengthening its brand will allow it to expand into a new distribution channel and also enable a strategic partnership with its competitor brands. The factors influencing 'boutique type' is personalization and uniqueness. With an emphasis on the uniqueness of products and merchandising it will be able to implement the role as a personal shopper and stylist to provide a very personalized service to its customers.

Purpose - Since Iran's economy is only now developing, and its stock market is only now emerging, we should deal with the relationship between ownership structure and conservative accounting of companies to see whether such a relationship exists in Iran's market. This study aims to investigate the relationship between ownership structure and accounting conservatism of listed companies on the Tehran Stock Exchange. Research design, data, and methodology - All listed companies on the Tehran Stock Exchange, for which the required information financial statements (balance sheet, profit and loss account) could be acquired for the period 2007-2012, were studied. A total of 123 companies from various industries was selected. Results - In order to test the hypotheses, multi variate regression (inter procedure), with their meaningful t- and f-statistics, and a Durbin-Watson autocorrelation model were used. Conclusions - The research results show that the ownership of major shareholders and ownership concentration have a negative significant relationship with accounting conservatism. Therefore, as a significant negative relationship between concentration of ownership and accounting conservatism at the 95% confidence level was found, the second hypothesis was confirmed.

The purpose of this study is to verify the relationships among innovative behavior, turnover intention, and job security. An additional purpose was to examine partial mediating effects on psychological ownership. The baseline of analyzing those relationships in this study is that the role of psychological ownership will be a mediator between job security and turnover intention as well as innovative behavior in the organization. To accomplish these purposes, a model was built among job security as predictor variable, the psychological ownership as mediating variable and turnover intention, and innovative behavior as criteria variables based on the studies conducted in the various areas. The 248 questionnaires surveyed from the area of DaeGu and Kyungbuk were used in the statistical analyses. The detail statistical techniques are such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, and multi regression analysis. The results of the study show that job security had positively significant effect on turnover intention and innovative behavior. In addition, only the psychological ownership of organization-level thinking have partial mediating effects between job security and innovative behavior also job security and turnover intention. The results may indicate that the psychological ownership of organization-level thinking be a key factor to alleviate the turnover intention of employees and to encourage the innovative behavior during their works for the small-medium size companies showing the unstable job security.

The characteristics of agricultural water rights in multi-purpose dams in Korea was examined. The river system with multi-purpose dams can be divided into national river system and WRC(Water Resources Corporation) river system according to ownership of dam use rights. While the national river system have permitted water rights, the WRC river system have vest water rights and contract water rights. The two river systems have different characteristics of agricultural water rights, and therefore the water right of two system need to be unified. It is also known that water release from multi-purpose dams against water demand does not satisfy agricultural water rights.

Replacement demand plays an important role to forecast the total demand of durable goods, while most of the diffusion models deal with only adoption data, namely initial purchase demand. This paper presents replacement demand forecasting models incorporating repurchase rate, multi-ownership, and dynamic product life to complement the existing diffusion models. The performance of replacement demand forecasting models are analyzed and practical guidelines for the application of the models are suggested when life distribution data or adoption data are not available.

이 논문은 1987년 정간법 제정을 계기로 구축된 신문의 소유규제 제도가 2005년 신문법으로 전부 개정되면서 강화되었고, 2009년에 다시 개정되면서 위기에 직면하게 되는 과정을 언론법제사적 측면에서 검토한다. 1987년, 헌법 제21조 제3항의 신문기능 법정주의에 근거해서 정립된 신문의 소유규제 제도는 2005년 신문법으로 강화되었다가 2006년 신문법 헌법소원 결정에 따라 위축되기 시작한다. 2009년 신문법과 방송법이 개정되면서 신문 방송 겸영 규제, 복수신문 소유 규제 등은 존재하지 않게 되었다. 그 과정에서 야당도 신문방송의 제한적인 교차소유를 허용하였기 때문에 1987년에 형성된 신문소유 규제 제도는 해체 위기에 직면했다. 신문방송의 교차소유 허용 등의 규제완화가 미디어환경의 변화와 여론지배력의 추이 등을 장기적으로 검토하고 결정해야 할 정책적인 사안임에도 불구하고 이렇게 단기간에 도입하는 것은 위험한 일이다. 신문은 정치여론 형성에 있어서 지상파방송과 함께 강력한 미디어이다. 신문여론시장을 과점하고 있는 신문들의 여론지배력이 보도방송 영역까지 전이될 수 있다는 우려를 무시하기 어렵기 때문이다. 미디어소유 집중으로 정치적 다원주의가 위축되어 궁극적으로 민주주의가 위협받을 개연성이 있다는 점에서 신문 소유규제의 완화는 장기적인 사회적 논의가 전제되어야 할 것이다.

A zero-watermarking algorithm in transform domain based on RGB channel and voting strategy is proposed. The registration and identification of ownership have achieved copyright protection for color images. In the ownership registration, discrete wavelet transform (DWT), discrete cosine transform (DCT), and singular value decomposition (SVD) are used comprehensively because they have the characteristics of multi-resolution, energy concentration and stability, which is conducive to improving the robustness of the proposed algorithm. In order to take full advantage of the characteristics of the image, we use three channels of R, G, and B of a color image to construct three master shares, instead of using data from only one channel. Then, in order to improve security, the master share is superimposed with the copyright watermark encrypted by the owner's key to generate an ownership share. When the ownership is authenticated, copyright watermarks are extracted from the three channels of the disputed image. Then using voting decisions, the final copyright information is determined by comparing the extracted three watermarks bit by bit. Experimental results show that the proposed zero watermarking scheme is robust to conventional attacks such as JPEG compression, noise addition, filtering and tampering, and has higher stability in various common color images.

Purpose: This paper investigated the effects of issue leadership on employees' work performance. It also explored the mediating role of job challenge in the above relationship. We also tested the moderating effect of psychological ownership in the relationship between issue leadership and job challenge. Finally, this paper examined the moderated mediation effect of psychological ownership in the course of affecting issue leadership on work performance via job challenge. Methods: This paper used a cross-sectional design with questionnaires administered to 390 employees working in Korean firms. It applied an hierarchical and multi-regression analysis by using SPSS 22.0 and Hayes' Macro Process to test the proposed hypotheses including a moderated mediation model. Results: As a result of the analysis, first, it was found that the issue leadership had a positive effect on the work performance. Second, it was also found that issue leadership had a positive effect on the job challenge. In addition, job challenge was found to positive mediating effect in the relationship between issue leadership and work performance. Third, we found that the psychological ownership positively moderated the relationship between issue leadership and job challenge. Finally, the moderated mediating effect was found by confirming that the higher the degree of psychological ownership, the stronger the effect of issue leadership on the work performance via job challenge. Conclusion: This paper contributes to the leadership and work performance studies by identifying the role of issue leadership enhancing employee work performance while confirming connection mechanism and boundary conditions strengthening the positive effect of issue leadership on employee work performance.

본 논문에서는 소유권 보호와 변질검증이라는 두 가지 목적을 동시에 만족시키기 위한 다중 워터마킹 알고리즘을 제안한다. 먼저 강인한 워터마킹을 위해 기존의 QSWT 알고리즘을 이용하여 웨이블릿 계수에 워터마크가 삽입될 위치를 정한 후, 워터마크 영상을 DCT변환하여 삽입하는 알고리즘을 제안하였다. 다음으로, 워터마킹된 영상은 다시 변질검증을 위해 또 다시 워터마킹된다. 변질검증을 위한 알고리즘도 본 논문에서 새롭게 제안한다. 실험결과에 의해 제안한 다중 워터마킹 알고리즘은 blurring, sharpening 및 JPEG 압축 등의 공격에 강인함을 보인다. 또한 변질검증 워터마킹 기법에 의해 변질된 영역을 쉽게 판별하였다.

광도 요소의 워터마크 내장은 컬러 영상을 그레이 스케일 영상과 같은 변형에서 삽입한 소유권 정보의 추출을 보장하기 때문에 YCbCr와 같은 광도-색차 컬러 공간에서 색상의 광도 요소에 소유권 정보를 내장한다. 따라서 본 논문은 워터마크의 견고성과 비시각성에 중점을 두고, 멀티미디어 컨텐츠서비스의 장치와 성능을 고려한 컬러 영상의 워터 마크 내장, 추출 및 인증 알고리즘을 제안한다. 컬러 영상은 RGB 컬러 공간에서 YCbCr 컬러 공간으로 변형 한 다음 Y(Luminance), Cb(Color Differences) 및 Cr(Color Differences) 각 요소의 특성을 고려하여 웨이브릿 기반의 주파수 영역에서 다중 레벨(Multi-Level)의 워터마크를 내장하고 추출 및 인증한다. 실험 결과, JPEG 압축에 따른 견고성과 다중 레벨에 대한 워터마크의 비 시각성을 보장할 수 있었다
