The purpose of this study is to explore the subjective perception of college students' Internet addiction by applying photovoice method, a participatory research method. The subjects of the study were nine university students at G University. The data were analyzed by orientation, photo collection, photo selection, contextualizing and codifying according to the general photo voice research procedure.As a result, 15 sub-categories were derived based on the meaning of Internet addiction, the effects of Internet addiction on life, and how to get out of Internet addiction. The perception of the meaning of Internet addiction was divided into five categories: 'loss of self-regulation', 'habit without exit', 'disconnection from the world', 'loss of me', and 'voluntary prison'. The effects of Internet addiction on life were 5 categories: 'health deterioration', 'social isolation', 'broken daily life', 'anonymous violence' and 'my discovery and life extension'. In terms of how to get out of internet addiction, 'self-looking', 'new hobbies', 'nearby', 'reality meetings', and 'forced blocking' were derived. It suggested the discussion about Internet addiction viewed by college students and the implications of constructing a counseling program that can help to use the Internet correctly.

This paper proposes a design of W-band mm-wave wideband monopulse comparator using waveguide structure for applications. The main idea of proposed design is to combine a self-compensating phase shifter on $90^{\circ}$ hybrid for wideband $180^{\circ}$ hybrid. Using multiple conventional phase shifters, because of their narrow-band characteristics, tends to restrict working bandwidth of system including antennas. Proposed comparator could relieve the problem since it applies the self-compensating phase shifter. The comparator has waveguide structure so it shows excellent characteristic in loss. It also show wideband characteristic in amplitude and phase response between ports.

In order to visualize point based Location-Based Social Network Services(LBSNS) data on multi-scaled tile map effectively, it is necessary to apply tile-based clustering method. Then determinating reasonable numbers and size of tiles is required. However, there is no such criteria and the numbers and size of tiles are modified based on data type and the purpose of analysis. In other words, researchers' subjectivity is always involved in this type of study. This is when Modifiable Areal Unit Problem(MAUP) occurs, that affects the results of analysis. Among LBSNS, geotagged Twitter data were chosen to find the influence of MAUP in scale effects perspective. For this purpose, the degree of spatial autocorrelation using spatial error model was altered, and change of distributions was analyzed using Morna's I. As a result, positive spatial autocorrelation showed in the original data and the spatial autocorrelation was decreased as the value of spatial autoregressive coefficient was increasing. Therefore, the intensity of the spatial autocorrelation of Twitter data was adjusted to five levels, and for each level, nine different size of grid was created. For each level and different grid sizes, Moran's I was calculated. It was found that the spatial autocorrelation was increased when the aggregation level was being increased and decreased in a certainpoint. Another tendency was found that the scale effect of MAUP was decreased when the spatial autocorrelation was high.

This study examined the moderating effects of age and gender on the relationship between values and communication styles of Korean adults. Five hundred adult men and women across the country responded the questionnaires regarding cultural universal values (openness to change, self-enhancement, conservatism, and self-transcendence), cultural-specific values (collectivism, conformity to norms, emotional self-control, family recognition through achievement, and humility), high-context communication style, and low-context communication style. The results of this study are as follows. First, as a result of exploring the factors influencing the communication style, self-enhancement, emotional self-control, and self-transcendence significantly predicted the high-context communication style. Whereas openness to change, self-enhancement, conformity to norms, emotional self-control, and gender significantly predicted the low-context communication style. Second, age moderated the relationship between self-enhancement and high-context communication style. The high-context communication style significantly increased when the level of self-enhancement was high and the age was younger. Third, age and gender moderated the relationship between conformity to norms and high-context communication style. In the case of males with high conformity to norms and younger age, the high-context communication style significantly increased. Fourth, gender moderated the relationship between collectivism and low-context communication. As collectivism increased, men tended to increase low-context communication styles, while women tended to decrease it. Fifth, gender moderated the relationship between humility and low-context communication. In the case of women with high humility, their low-context communication style was significantly lowered. The implications and limitations of the results of this study were discussed.

Purpose : To investigate the feasibility of in vivo proton magnetic resonance spectroscopy (MRS) for evaluation of lung cancer. Materials and Methods: This prospective study was approved by the institutional review board of our hospital and informed consent was obtained in all patients. Ten patients (7 men, 3 women; mean age, 64.4) with pathologicallyproven lung cancer (mean, 56.8 mm; range, 44-77 mm) were enrolled to 1.5 T MRS using a single-voxel respiration-triggered point-resolved spectroscopic sequence. Technical success rate and the reason of technical failure, if any, were investigated. Results: Out of 10 lung cancers, analyzable MRS spectra were obtained in 8 tumors (technical success rate, 80%). Two MRS datasets were not able to be analyzed due to serious baseline distortion. Choline and lipid signals were detected as major metabolites in analyzable MRS spectra. Conclusion: In vivo proton MRS method using a single-voxel respiration-triggered point-resolved spectroscopic sequence is feasible in obtaining the MR spectra of lung cancer because these spectra were analyzable and high success rate was shown in our study although there was the limitation of small patient group.
