Purpose: Companies in haste for higher consumers' preference tend to appear as 'green' and mislead about environmental concerns, which are termed as "Greenwashing." The purpose of the study is to investigate the consumer perception on greenwashing activities and analyze its impact on green brand image, green brand loyalty and green brand trust among Indian consumers. Design/methodology: The study makes use of a written questionnaire method to collect survey data from approximately 500 consumers all over India. The study uses Structural Equation Modeling (SEM) to study the hypothesized relationship between constructs affected by greenwashing based on consumer perspective in the Indian context. Findings: The study shows that Indian consumers are becoming aware of greenwashing activities, which have a negative impact on green brand trust and undermines green brand image and green brand loyalty. Implications: The study results are beneficial to policy-makers, researchers, practitioners, and managers to create awareness among Indian consumers on greenwashing activities.

Nondestructive testing, which can monitor a product's interior without disassembly, is becoming increasingly essential for industrial inspection. Computed laminography (CL) is widely used in this application, as it can reconstruct a product, such as a printed circuit board, into a three-dimensional (3D) high-magnification image using X-rays. However, such high-magnification scanning environments can be affected by minute vibrations of the CL device, which can generate motion artifacts in the 3D reconstructed image. Since such vibrations are irregular, geometric corrections must be performed at every scan. In this paper, we propose a geometry calibration method that can correct the geometric information of CL scans based on the image without using geometry calibration phantoms. The proposed method compares the projection and digitally reconstructed radiography images to measure the geometric error. To validate the proposed method, we used both numerical phantom images at various magnifications and images obtained from real industrial CL equipment. The experiment results confirmed that sharpness and contrast-to-noise ratio (CNR) were improved.

고해상도 위성영상융합은 다중분광영상의 공간해상도를 향상시키기 위한 영상처리과정으로서 원격탐사 영상분석에서 그 중요성이 날로 커지고 있다. 고해상도 위성영상의 융합과정은 크게 다중분광영상의 크기 조절을 위한 업샘플링 과정과 흑백영상을 이용한 고주파 정보 주입과정으로 나눌 수 있다. 하지만 다중분광영상의 공간해상도를 강제적으로 키우는 업샘플링 과정에서 영상열화 현상이 수반되고 이는 이후 융합과정에서 분광정보를 왜곡시키는 하나의 원인이 된다. 이러한 문제를 해결하기 위해 본 연구에서는 최적화 기법에 근간을 둔 영상복원기법들을 위성영상 융합과정에 도입하여 이들의 효용성과 활용가능성을 평가하고자 하였다. 영상복원 기법들이 미치는 영향을 평가하기 위해 기존에 위성영상융합에 많이 사용된 공삼차 보간법을 이용한 방법과의 시각적/정량적 비교평가를 수행하였다. 정량적 비교평가 방법으로는 동일한 조건하에서 생성된 융합영상에 대한 분광왜곡 측정치를 이용하였다.

The purpose of this study was to investigate the make-up preference images influenced by the clothing preference images group, and importance orders among the make-up preference images. The questionnaires were given to female residents in the ages between $20{\sim}45$ in Seoul and Kyung-gi province during October 2004. 322 questionnaires were used for data analysis. The collected data were analyzed by using SPSS 10.0 software with various techniques such as ANOVA test, Duncan test and paired t-test. The results of this study as follows; 1. It was found out that the graceful, chic, and modern make-up image had significant differences. The graceful make-up preference image was preferred by the graceful clothing preference image group. The chic and modern make-up preference image were preferred by modern clothing preference image group. It was confirmed that the categories with significant differences were those with the same clothing and make-up preference image groups, which indicate people prefer unified image coordination. 2. As the results of the analysis of the difference in importance of make-up preference images, it was found out that the natural make-up preference image was the most preferred by people, and followed by the youthful make-up preference image. On the other hand, the romantic make-up preference was preferred the least. This study on relationships between clothing images and make-up images found that the costume culture is becoming more of 'total fashion' and that it would be beneficial for clothing brands to incorporate cosmetics in their business strategies and expand their businesses.

Due to the belief that housing for university students is uniform materialistic and non-human, a variety of needs and preferences of the residents is becoming more important. In order to more positively identify the user's emotional needs, a design that meets the needs of the resident's living space is absolutely necessary. The purpose of this study is to group the sensibility types of university students, to analyze the preferred interior image and interior design elements, and then to understand the preferred characteristics according to sensibility type. To collect the data, a survey method was used for 224 university students in Seoul and the metropolitan area. The data analysis used SPSS PC 14.0 to find the frequency, t-test, chi-square, factor analysis, and cluster analysis. The results of the analysis are as follows: First, sensibility types were segmented into four groups including 'Unique & Elegant', 'Static & Tidy', 'Warm & Comfortable', and 'Characteristic & Free'. Second, the preferred interior image was the Minimal-Dandy-Natural Image, the preferred floor_material was wood, and the preferred wall_material was marble. Third, there were different interior preferences according to each type of gender & sensibility.
