Purpose: This study investigated the rate of attempts to quit smoking and related factors in Korean adolescent smokers. Methods: The findings of this study were based on the data obtained from the '2015 $11^{th}$ Korea Youth Risk Behavior Web-based Survey'. The number of subjects was 5,123. Results: 71.7% of adolescent smokers in our study group had made previous attempts to quit smoking. Logistic regression analysis showed that the following significant factors were related to attempts to quit smoking: smoking amount (OR=1.78, 95% CI=1.42~2.23), experience of secondhand smoking in family (OR=1.16, 95% CI=1.02~1.32), experience of smoking cessation education in school (OR=2.05, 95% CI=1.79~2.35) anti-smoking publicity (OR=1.34, 95% CI=1.17~1.55), and close friend's smoking (OR=1.63, 95% CI=1.24~2.17). Conclusion: Smoking cessation policies and programs, especially those targeting adolescent smokers, should consider the factors mentioned above when designing new interventions or campaigns.

Nuclear magnetic resonance (NMR) spectroscopy, owing to its ability to provide atomic level information on molecular structure, dynamics and interaction, has become one of the most powerful methods in early drug discovery where hit finding and hit-to-lead generation are mainly pursued. In recent years, drug discovery programs originating from the fragment-based drug discovery (FBDD) strategies have been widely incorporated into academia and industry in which a wide variety of NMR methods become an indispensable arsenal to elucidate the binding of small molecules onto bimolecular targets. In this review, I briefly describe FBDD and introduce NMR methods mainly used in FBDD campaigns of my company. In addition, quality control of fragment library and practical NMR methods in industrial aspect are discussed shortly.

KOMPSAT-2, the first Korean high resolution earth observing satellite, continuously acquires high resolution images since July 2006. The quality of satellite images should be geometrically and radiometrically ensured before distribution to users. This study focused on absolute radiometric calibration which is a prerequisite procedure to ensure the radiometric quality of optical satellite images. In this study, we performed reflectance-based vicarious calibration methods on several uniform targets collected through several field campaigns in 2007. The radiative transfer model, MODTRAN, was used to estimate the amount of energy received at the sensor. The energy reached at the sensor are affected by several factors such as reflectance of targets, atmospheric condition, geometry condition between Sun and the sensor, etc. This study proposes the absolute radiometric calibration coefficients of KOMPSAT-2 MSC images combining several types of collected data through field works and tried to compare dynamic range of sensor-detected energy with other commercial high resolution sensors.

This study is to investigate the cognition and usage of traditional wedding food in Seoul & Gyeonggi area. It provides the basic suggestions for developing the best wedding culture, upholding the great wedding tradition. People usually prepared traditional wedding food only because they had to do since they thought it was a formal way to do it at a wedding ceremony. However, there should be more important things to be considered. Firstly, to understand the real meaning of traditional wedding food, we need to inform its meaning by starting campaigns on wedding culture or making booklets of traditional wedding food. Secondly, to prepare the right selections of traditional food, we need to simplify traditional wedding food and consider the modern sense of the products. Thirdly, to improve traditional wedding food, we need to develop diverse menu. By doing it, we can efficiently reduce the cost of wedding food.

The purpose of this paper is to analyze the trends of Policies and law related to web accessibility in developed countries such as U.S, U.K, Australia, Japan and EU and then propose polices to improve web accessibility in Korea. The results of the paper are as follows ; First, the awareness promotion programs, i.e seminars, campaigns, contests, etc., should be provided. Second, Korean standards and guidelines which have specific information should be made to improve web accessibility. Third, Web accessibility specialist should be trained. Finally, Law and regulation related to web accessibility should be amended as the Section 508.

This paper presents millimeter-wave (mmWave) propagation characteristics and channel model parameters including path loss, delay, and angular properties based on 28 GHz and 38 GHz field measurement data. We conducted measurement campaigns in both outdoor and indoor at the best potential hotspots. In particular, the model parameters are compared to sub-6 GHz parameters, and system design issues are considered for mmWave 5G Giga communications. For path loss modeling, we derived parameters for both the close-in free space model and the alpha-beta-gamma model. For multipath models, we extracted delay and angular dispersion characteristics including clustering results.

An online survey was conducted to assess motivations for using, reliance on, and perceived credibility of political blogs and microblogs during both the Taiwanese general election of 2009 (the blog epoch) and the presidential elections of 2012 (the microblog epoch). Results indicated higher reliance on and motivation for using political blogs than microblogs. Blogs were also perceived to be more credible than microblogs. Respondents who primarily engaged in blogging for information purposes were more likely to judge candidate blogs as highly credible, whereas interest in entertainment emerged as the strongest predictor of the perceived credibility of microblogs. This research also provided quantitative evidence showing how users viewed blogs and microblogs differently in the context of political campaigns. The aim is to explore the pros and cons of blogging and microblogging as a tool for political communication.

The government of Korea enacted the National Health Promotion Act in 1995, and set aside funds for national health promotion, endeavoring to reduce the smoking rate of its citizens. Consequently, smoking rates in all age groups of both sexes were lowered during the period of 1999-2003 when legal backing and financial support for no-smoking policies from the national health promotion funds were provided. The decrease in the smoking rate is attributed to the combined effort of the fact that enactment of related acts, their implementation, financial support, and education and publicity 'campaigns on no smoking. However, at the current pace of decreasing the smoking rates, it will be difficult to achieve the Health and Welfare Ministry's smoking rate goal of30％ among adult males by 2013. Thus, related acts should be reshaped, corresponding support should be increased, and financial support should also be provided to implement comprehensive no-smoking policies. Also, budgets should also be alloted to establish a system of providing feedback on the monitoring and evaluation of both short-term and long-term no-smoking business planning and implementation.

In k-means clustering, we standardize variables before clustering and iterate two steps: units allocation by Euclidean sense and centroids updating. In applications to DB marketing where clusters are to be used as customer segments with similar consumption behaviors, we frequently acquire additional variables on the customers or the units through marketing campaigns a posteriori. Hence we need to modify the clusters originally formed after each campaign. The aim of this study is to propose a revision method of k-means clusters, incorporating added information by weighting clustering variables. We illustrate the proposed method in an empirical case.
