이 연구에서는 해양경찰조직 내에서 발생하는 다양한 갈등을 진단하고 더불어 갈등을 유발시킬 수 있는 해양경찰조직의 지배적인 주류문화와 다르게 형성되어 있는 하위문화에 대해 살펴보고자 한다. 아울러 해양경찰조직 자체가 가지고 있는 관료제적 가치와 민주적 가치와의 균형이나 대립 그리고 모순으로 인한 보편화된 갈등과 마찰에 대해 논의하고자 한다. 해양경찰의 하위문화가 조직 갈등에 미치는 영향에 대한 분석결과를 살펴보면 다음과 같다. 첫째, 냉소주의가 기능적 갈등에 미치는 영향 중에는 피조사자의 거짓말과 경찰에 대한 비신뢰성이 강할수록 기능적 갈등을 겪는 것으로 나타났고, 계층적 갈등에서는 경찰업무에 대한 비협조와 비신뢰성이 강할수록 계층적 갈등을 겪는 것으로 나타났다. 둘째, 남성주의가 기능적 갈등에 미치는 영향에서는 여자경찰관들은 남자경찰관들에 비해 직무수행 능력이 저조하기 때문에 갈등을 겪는 것으로 나타났고, 계층적 갈등에서는 여성경찰관의 직무범위를 축소하고 직무수행능력이 저조하여 갈등을 겪는 것으로 나타났다. 셋째, 변화거부주의가 기능적 갈등에 미치는 영향은 통계적으로 유의미하지 않으며, 상대적인 범죄통제 지향주의에서는 범죄의 통제를 위한 공격적인 태도와 범죄와 무관한 업무를 지양할 경우에 기능적 갈등에 영향을 미치는 것으로 나타났고, 계층적 갈등에서는 공격적인 태도와 범죄와 무관한 업무를 수행할 때에 계층적인 갈등을 겪는 것으로 나타났다.

We present optical follow-up observation results of three binary black hole merger (BBH) events, GW190408 181802, GW190412, and GW190503 185404, which were detected by the Advanced Ligo and Virgo gravitational wave (GW) detectors. Electromagnetic (EM) counterparts are generally not expected for BBH merger events, however, some theoretical models suggest that EM counterparts of BBH can possibly arise in special environments. To identify EM counterparts of the three BBH merger events, we observed high-credibility regions of the sky with telescopes of the Gravitational-wave EM Counterpart Korean Observatory (GECKO), including the Korea Microlensing Telescope Network (KMTNet). Our observation started as soon as 100 minutes after the GW event alert and covered roughly 29 - 63 deg2 for each event with a depth of 22.5 mag in R-band within hours of observation. No plausible EM counterparts were found for these events. Our result gives a great promise for the GECKO facilities to find EM counterparts within few hours from GW detection in future GW observation runs.

Recently, many patients in a hospital are threatened life by fire disaster. Because many patients like vulnerable people have more evacuation problem than ordinary person. So a patient who can escape by oneself with walking assistance device like crutches or wheelchair and another patient who can't escape by oneself are should be supported safety technologies and service. Earlier research of 'hospital evacuation' led by actual experiments or computer evacuation simulation. Actual experiment is effective to gain credibility of result but it is difficult for patients to experiment repeatedly and it requires consideration for spatial problem and economic problems. Although computer evacuation simulation have been used to solve these problems, almost have concluded only results based on velocity without evacuation device. In this study, evacuation results with support device application or not are analysed used by computer evacuation simulation based on MAS(Multi Agent System). As a result, it is drawn through proof of efficiency of evacuation device in the vertical space like stairs that can improve the evacuation plan for vulnerable people in the hospital.

This study investigated the consumer review information considered important by consumers when making a purchase decision to buy apparel products online. Data were collected through focus group interviews. Eleven females in their 20s and 30s, who have extensive experience in reading consumer reviews posted on online apparel stores, participated in the study. The consumer review information considered important by participants is the information related to seven product attributes (size, fabric, design, color, sewing, price, and country of origin), seven benefits (functional, financial, esthetic, emotional, social, utilitarian benefits, and product value compared to price) of the apparel product and four store attributes (return/refund, delivery, reputation/credibility, and customer service). The findings from the study can serve as an important tool in developing survey questions in order to evaluate the quality of consumer review information and help online retailers plan methods to improve the quality of reviews.

The purposes of this study were to examine the effect of perceived service quality and symbolic store image on store loyalty in apparel product purchasing and the moderating effect of hedonic shopping orientation. The questionnaire was administered to 450 women shopped in a department store in Gwang-ju during September, 12-26, 2002. Data collected from 384 women were analyzed by using frequency, factor analysis, regression analysis, ANOVA and t-test by SPSS for WIN Program. The results were as follows. First, consumers' perceived service quality was composed of three factors; product & environment service, sales person's customer oriented service, store policy service factor. Consumers' symbolic store image was composed of three factors; status symbol, favorability. credibility (actor. Second, the perceived service quality significantly influenced store loyalty. Third, the symbolic store image significantly influenced store loyalty. Fourth, interaction effect between perceived service quality and hedonic shopping orientation was found out to be meaningful at store loyalty. Fifth, interaction effect between perceived store image and hedonic shopping orientation was found out to be meaningful at store loyalty.

Grounding line of a glacier or ice shelf where ice bottom meets the ocean is sensitive to changes in the polar environment. Recent rapid changes of grounding lines have been observed especially in southwestern Antarctica due to global warming. In this study, ERS-1/2 and Sentinel-1A Synthetic Aperture Radar (SAR) image were interferometrically acquired in 1996 and 2015, respectively, to monitor the movement of the grounding line in the western part of Ronne Ice Shelf near the Antarctic peninsula. Double-Differential Interferometric SAR (DDInSAR) technique was applied to remove gravitational flow signal to detect grounding line from the interferometric phase due to the vertical displacement of the tide. The result showed that ERS-1/2 grounding lines are almost consistent with those from Rignot et al. (2011) which used the similar dataset, confirming the credibility of the data processing. The comparison of ERS-1/2 and Sentinle-1A DDInSAR images showed a grounding line retreat of $1.0{\pm}0.1km$ from 1996 to 2015. It is also proved that the grounding lines based on the 2004 MODIS Mosaic of Antarctica (MOA) images and digital elevation model searching for ice plain near coastal area (Scambos et al., 2017), is not accurate enough especially where there is a ice plain with no tidal motion.

Numerical prediction of dynamic behavior of fully coupled saturated porous media is of great importance in many engineering problems. Specifically, static and dynamic response of soils - porous media with pores filled with fluid, such as air, water, etc. - can only be modeled properly using fully coupled approaches. Modeling and simulation of static and dynamic behavior of soils require significant Verification and Validation (V&V) procedures in order to build credibility and increase confidence in numerical results. By definition, Verification is essentially a mathematics issue and it provides evidence that the model is solved correctly, while Validation, being a physics issue, provides evidence that the right model is solved. This paper focuses on Verification procedure for fully coupled modeling and simulation of porous media. Therefore, a complete Solution Verification suite has been developed consisting of analytical solutions for both static and dynamic problems of porous media, in time domain. Verification for fully coupled modeling and simulation of porous media has been performed through comparison of the numerical solutions with the analytical ones. Modeling and simulation is based on the so called, u-p-U formulation. Of particular interest are numerical dispersion effects which determine the level of numerical accuracy. These effects are investigated in detail, in an effort to suggest a compromise between numerical error and computational cost.

Objectives: The purpose of this study was to examine health information seeking behavior of people with cancer in terms of information seeking or avoiding behavior and the differences of the two groups in demographic and disease variables. Methods: Data were collected from October 21 to December 5 in 2013 from out-patient clinics of a university affiliated hospital in Suwon, Korea. One hundred (100) patients with cancer were participated in this study. Health Information National Trends Survey Questionnaires (National Cancer Institute, 2007) was used. Results: Three quarters (n=77) of the participants were in health information seeking group while 23% were in health information avoiding group. Participants who were female, higher education were more likely to seek health information than their counter parts. Among participants, a considerable number of cancer patients intentionally avoided information due to either the lack of accessibility of information source or the lack of credibility of information from the sources. Conclusion: Significant differences in gender and educational level were found in the two groups. Different approaches for both groups were necessary to increase information seeking behavior. And barriers of the information avoiding group should be considered in designing interventions to fill the gap between seekers and avoiders.
