본 연구에서는 직접비교 광고와 간접비교 광고 그리고 일반광고와 비교하여 브랜드 태도 형성에 영향을 미치는 감정적(광고 태도), 인지적(브랜드 인지) 변수의 상대적 영향력을 측정하였다. 분석결과 직접비교 광고에서는 브랜드 인지가 브랜드 태도에 미치는 영향력이 광고 태도가 브랜드 태도에 미치는 영향력에 비해 훨씬 큰 것으로 나타났다. 간접비교 광고에서도 마찬가지로 브랜드 인지가 광고 태도에 비해 브랜드 태도에 더욱 큰 영향을 미치는 것으로 나타났으나, 직접비교 광고에 비해 그 차이가 상대적으로 작게 나타났다. 반면 일반광고에서는 광고 태도의 영향력이 브랜드 인지에 비해 더욱 큰 것으로 나타났다. 이번 연구를 통해 직접비교 광고뿐만 아니리 간접비교 광고에서도 소비자들이 인지적 노력을 통해 태도가 형성됨을 알 수 있었다. 따라서 그동안 국내 기업들이 상대적으로 꺼려왔던 직접비교 광고가 간접비교 광고에 비해 오히려 더욱 효과적일 수 있을 것으로 기대된다.

In an experiment to determine the relative effectiveness of poetry activities through constructivist cooking experiences 95 children in three kindergarten classes were assigned to experimental, comparative, and control groups. The experimental group participated in 12-week units of writing poetry after cooking experiences, while the comparative group participated in writing poetry after listening to poetry. Analysis of covariance revealed differences between the mean scores of the three groups on posttests of receptive and expressive language, indicating that the children in the experimental group performed better on the tests than the children in the comparative and control groups. These results suggest that incorporating constructivist cooking into poetry instruction is an effective means of fostering the language development of young children.

This study was undertaken to measure the diffusibility and antimicrobial effectiveness of the medication used in clinical practice. To study the diffusibility of the root canal medicament, loss of formocresol and camphorated phenol from a cotton pellet after insertion into the pulp chamber of 260 molars prepared as routine endodontic treatment was measured. Measurement was done for the one time insertions and for the reinsertions using ultraviolet spectrophotometer. Antibacterial effectiveness against three microoganisms, Staphylococcus aureus, Staphylococcus epidermidis and a-hemolytic streptococcus, on the blood agar plate was observed by measurement of the inhibition zone with. various amount of medicaments. The following results were observed. 1. Nearly all of the medication were lost in the first day after insertion and the residual amount of camphorated phenol was greater than that of formocresol. 2. Residual amounts of medication in the reinsertion group were greater than that of the one time insertion group. 3. Within the pulp chamber diffusibility of formocresol was greater than that of camphorated phenol. 4. The amount of formocresol diffusing out from the tooth was greater than that of camphorated phenol. 5. Antibacterial effectiveness was observed from the residual amount of formocresol in the reinsertion group and in other groups no antibacterial effectiveness was observed.

Underfloor air distribution system is generally known to be more energy-saving and provide more comfort as compared with overhead air distribution system. In practice, however, some buildings to which underfloor air distribution system is applied have less effectiveness in saving energy and are getting dissatisfaction with cold draft caused by wind velocity of air distribution in terms of comfort. It is judged that such problems are due to failure to consider properties of underfloor air distribution system in applying it and identical design with the design standards for the existing overhead air distribution system. This study aims at introducing an air conditioning type of the occupied zone for underfloor all distribution system to see its effectiveness in saving energy for air conditioning of the occupied zone through a comparative simulation with the existing air conditioning type.

Face-based video retrieval has become an active and important branch of intelligent video analysis. Face profiling and matching is a fundamental step and is crucial to the effectiveness of video retrieval. Although many algorithms have been developed for processing static face images, their effectiveness in face-based video retrieval is still unknown, simply because videos have different resolutions, faces vary in scale, and different lighting conditions and angles are used. In this paper, we combined content-based and semantic-based image analysis techniques, and systematically evaluated four mainstream local features to represent face images in the video retrieval task: Harris operators, SIFT and SURF descriptors, and eigenfaces. Results of ten independent runs of 10-fold cross-validation on datasets consisting of TED (Technology Entertainment Design) talk videos showed the effectiveness of our approach, where the SIFT descriptors achieved an average F-score of 0.725 in video retrieval and thus were the most effective, while the SURF descriptors were computed in 0.3 seconds per image on average and were the most efficient in most cases.

Objectives: By comparing and analyzing the legal system for risk assessment in South Korea with other advanced countries, the study is designed to identify the key elements of risk assessment and seek improvement measures while focusing on solutions to the execution of risk assessment violations. Methods: The study started with an awareness of the need to improve the legislation on the risk assessment of businesses in Korea. In order to reflect this problem consciousness in Korea's industrial safety and health legislation, risk assessment legislation in Japan, Britain, Germany, and Korea was analyzed in comparative terms through the literature. Results: Unlike the other advanced countries, the concept of risk assessment is defined in Korea in a broad sense that includes measures to reduce risk, and risk assessment in the manufacturing and design stages is not institutionalized. In the case of worker participation, there is a problem regarding effectiveness. It is problematic that compared to the other foreign countries there is a possibility that general risk assessment will be neutralized because it is recognized as a uniform general risk assessment for a particular risk assessment, as well as inadequate risk assessment. Conclusions: The areas diagnosed with problems compared to the legislation in other advanced countries should be improved by revising laws and administrative rules and supplementing the explanatory guidelines, etc. by referring to the legislation of these countries. In particular, the issue of enforcement for violations of risk assessment must be improved in order to ensure the effectiveness of risk assessment.

With the rapid growth in the use of digital advertising media among consumers, there is an increasing interest in the utilization of virtual advertising and PPL as an alternative to traditional television advertising. Nonetheless, few studies have compared the effects of these new advertising platforms, still lacking knowledge on their relative effects for maximizing advertising effectiveness. This study, thus, intends to compare virtual advertising and PPL with respect to advertising effectiveness (i.e., consumer evaluations of advertising attributes, brand attitudes, and purchase intentions), controlling for the level of product involvement. An experiment was conducted with a sample of 360 participants and actual ads were used as test stimuli. According to the results, consumers exhibit more favorable evaluations on all the three advertising attributes (i.e., entertainment, informativeness, and irritation) for high-involvement products, whereas, for low-involvement products, virtual advertising is perceived to be more irritating than PPL. In particular, the effect of informational value of virtual advertising on brand attitudes was found to be most significant. In addition, for high-involvement products, virtual advertised products. Advertising practitioners may have to consider these results and fully utilize the advantages of virtual advertising and PPL in order to achieve maximum advertising effectiveness.
