Education is essential for specialists in charge terminal care of cancer patients. In the second 10-year plan to conquer cancer under the Cancer Control Act, the Korean government announced a plan to train more hospice and palliative care (HPC) specialists based on quantitative HPC expansion. Specifically, the government aims to develop e-learning programs to foster social workers in HPC, following those offered to doctors and nurses. In HPC, social workers have served a vital role in helping patients overcome psychological and social issues. As professionals, they have carried out their responsibilities and played their part in the field to help HPC to take root and be institutionalized in Korea. To date, it has been difficult to obtain practical knowledge and skills for social workers due to the lack of systematic training program. Development of an e-learning program for social workers, as proposed in this study, should strengthen social workers in charge of terminally-ill cancer patients in terms of their identity, expertise, and practical skills in clinical setting and improve their access to education. We also hope the program to be further developed by the government by introducing an education system that offers refresher courses to guarantee social workers' continued expertise through.

Rapid growth in computer and digital-based technology has brought about changes in various human services including psychotherapy. This paper will look into one of these changes, focusing on a rising area of mental health therapy : Art therapy. Although development of art therapy is not so fast compared to other branches of psychotherapy, some art therapists are studying how to adopt and use it properly. Both art therapists and mental health experts have concluded that technology is a powerful tool despite its limitations and reservations. While some of them think that patients have benefited from the implementation of technology, others have felt concerns about the replacement of basic professional practices. The use of digital technology in the area of art therapy, however, continues to increase, encouraging patients to benefit from it in various therapeutic processes. This thesis therefore focuses on the analysis of literature related to digital art therapy published up to now. The following field study on Korean art therapists aims to examine the current practice of digital art therapy and discuss its feasibility and future. These two methods will contribute to enhancing the understanding of art therapy not only in theory but in practice and also suggest how digital art therapy may overcome limitations of conventional art therapy by exploiting its advantages. Furthermore, this study will present some clues on a possible new position of digital art therapy in the future. I hope that this analytical examination on digital art therapy will stimulate further discussion on this issue and particularly encourage more interdisciplinary work between art therapy and digital technology.

Most of the problems in dealing with the tunnel construction are the uncertainties and complexities of the stress conditions and rock strengths in ahead of the tunnel excavation. The limitations on the investigation technology, inaccessibility of borehole test in mountain area and public hatred also restrict our knowledge on the geologic conditions on the mountainous tunneling area. Nevertheless an extensive and superior geophysical exploration data is possibly acquired deep within the mountain area, with up to the tunnel locations in the case of alternative design or turn-key base projects. An appealing claim in the use of artificial neural networks (ANN) is that they give a more trustworthy results on our data based on identifying relevant input variables such as a little geotechnical information and biological learning principles. In this study, error back-propagation algorithm that is one of the teaching techniques of ANN is applied to presupposition on Rock Mass Ratings (RMR) for unknown tunnel area. In order to verify the applicability of this model, a 4km railway tunnel's field data are verified and used as input parameters for the prediction of RMR, with the learned pattern by error back propagation logics. ANN is one of basic methods in solving the geotechnical uncertainties and helpful in solving the problems with data consistency, but needs some modification on the technical problems and we hope our study to be developed in the future design work.

Large scale secular registry or surveillance systems have been accumulating vast data that allow mathematical modeling of cancer incidence and mortality rates. Most contemporary models in this regard use time series and APC (age-period-cohort) methods and focus primarily on predicting or analyzing cancer epidemiology with little attention being paid to implications for designing cancer registry, surveillance or evaluation initiatives. This research models age-specific cancer incidence rates using logistic growth equations and explores their performance under different scenarios of data completeness in the hope of deriving clues for reshaping relevant data collection. The study used China Cancer Registry Report 2012 as the data source. It employed 3-parameter logistic growth equations and modeled the age-specific incidence rates of all and the top 10 cancers presented in the registry report. The study performed 3 types of modeling, namely full age-span by fitting, multiple 5-year-segment fitting and single-segment fitting. Measurement of model performance adopted adjusted goodness of fit that combines sum of squred residuals and relative errors. Both model simulation and performance evalation utilized self-developed algorithms programed using C# languade and MS Visual Studio 2008. For models built upon full age-span data, predicted age-specific cancer incidence rates fitted very well with observed values for most (except cervical and breast) cancers with estimated goodness of fit (Rs) being over 0.96. When a given cancer is concerned, the R valuae of the logistic growth model derived using observed data from urban residents was greater than or at least equal to that of the same model built on data from rural people. For models based on multiple-5-year-segment data, the Rs remained fairly high (over 0.89) until 3-fourths of the data segments were excluded. For models using a fixed length single-segment of observed data, the older the age covered by the corresponding data segment, the higher the resulting Rs. Logistic growth models describe age-specific incidence rates perfectly for most cancers and may be used to inform data collection for purposes of monitoring and analyzing cancer epidemic. Helped by appropriate logistic growth equations, the work vomume of contemporary data collection, e.g., cancer registry and surveilance systems, may be reduced substantially.

'Spectacles' and 'factuality' provided by computer technology are strengths of CG animation to still lure the audience and after commercial success of a number of theatrical CG animations whose typical producing companies are PIXAR and DreamWorks, were produced to be commercially successful and they win massive popularity even now. In Korea as well, several works tried to achieve a box office success including , , etc. but the result was truly miserable. In the past, this failure was often attributed to a lack of 'technical expertise', but it became clear that in the process of continuous trial and error, 'narrative' and 'images of imagination' which are bases and characteristics of animation are key elements of commercial success. Actually, statistics indicate that narrative is what is considered to be the most important by the audience when they select animation and its importance is so absolute that they say the most significant thing in animation is 'story.' In particular, it can be said that 'characters', 'situations', and 'ideas' play a key role in them which become elements of the story. This paper studied with what characteristics each animation aroused pleasure and fun focused on characters, situations and images in relation to , , and which are American theatrical CG animation films which succeeded in gaining popularity home and abroad. We hope that analysis in this paper will be helpful even just a little bit as a reference material, which allows domestic writers and producers to develop familiar and characteristic works based on imagination and creativity expressing each work's unique personality and characteristics.

This study examined the effects of a non-smoking program according to the stress and emotional condition of male office workers. As research subjects, 106 smokers at C company who participated in the campaign of "No Second-Hand Smoking and No Cigarette Smoke at Work" from April 25, 2011 to December, 2011 for 8 months were enrolled in this study. Apreliminary survey of the general characteristics, motivation to quit smoking, emotional condition, behavior to cope with stress, stress in life, hope, and the emotional variables of job satisfaction in the research subjects was carried out. The study undertook a pre-and-post effect analysis of the non-smoking program only with those who succeeded in quitting smoking. In terms of the general characteristics of the subjects, the success rate of quitting smoking was higher in those in their thirties and above and those who were married. No significant difference in the emotional variables was observed between those who were not successful and those who were. These results suggest that the motives for stopping smoking and effective dealing with stress or anxiety is important for male office workers to succeed in stopping smoking, based on which smoking cessation programs should be developed. In addition, the message of a smoking cessation campaign should be designed specifically for each target audience, effectively emphasizing the emotional aspects of each target group.

We propose a no-reference perceptual fog density and visibility prediction model in a single foggy scene based on natural scene statistics (NSS) and perceptual "fog aware" statistical features. Unlike previous studies, the proposed model predicts fog density without multiple foggy images, without salient objects in a scene including lane markings or traffic signs, without supplementary geographical information using an onboard camera, and without training on human-rated judgments. The proposed fog density and visibility predictor makes use of only measurable deviations from statistical regularities observed in natural foggy and fog-free images. Perceptual "fog aware" statistical features are derived from a corpus of natural foggy and fog-free images by using a spatial NSS model and observed fog characteristics including low contrast, faint color, and shifted luminance. The proposed model not only predicts perceptual fog density for the entire image but also provides local fog density for each patch size. To evaluate the performance of the proposed model against human judgments regarding fog visibility, we executed a human subjective study using a variety of 100 foggy images. Results show that the predicted fog density of the model correlates well with human judgments. The proposed model is a new fog density assessment work based on human visual perceptions. We hope that the proposed model will provide fertile ground for future research not only to enhance the visibility of foggy scenes but also to accurately evaluate the performance of defog algorithms.

This work is for the preliminary study for the calibration of an $^{192}Ir$ brachytherapy source based on an absorbed dose to water standards. In order to calibrate brachytherapy sources based on absorbed dose to water standards using a clyndirical ionization chamber, the beam quality correction factor $k_{Q,Q_0}$ is needed. In this study $k_{Q,Q_0}s$ were determined by both Monte carlo simulation and semiexperimental methods because of the realistic difficulties to use primary standards to measure an absolute dose at a specified distance. The 5 different serial numbers of the PTW30013 chamber type were selected for this study. While chamber to chamber variations ran up to maximum 4.0% with the generic $k^{gen}_{Q,Q_0}$, the chamber to chamber variations were within a maximum deviation of 0.5% with the individual $k^{ind}_{Q,Q_0}$. The results show why and how important ionization chambers must be calibrated individually for the calibration of $^{192}Ir$ brachytherapy sources based on absorbed dose to water standards. We hope that in the near future users will be able to calibrate the brachytherapy sources in terms of an absorbed dose to water, the quantity of interest in the treatment, instead of an air kerma strength just as the calibration in the high energy photon and electron beam.

The purpose of this study was to investigate the systematic and convergent education needs according to the use of digital intraoral scanners in dental hygienists. Data of 127 respondents who participated in an online survey for dental hygienists working at dental hospitals and clinics were analyzed by the frequency analysis, t-test, one way ANOVA, and correlation using SPSS 24.0 program. The utilization period of digital intraoral scanners in the hospital was 'less than 1 year' in 78.7%. As for relevant education experience, 58.3% answered 'no', showing a higher proportion of no education experience. As for clinical application of digital intraoral scanners, 77.4% responded that they use the scanner for clinical purposes. With regard to digital intraoral scanner education, 61.4% responded that education is necessary. This result reflects the fact that digital intraoral scanners have been rapidly introduced to dental hospitals and clinics, but systematic education has not been given. Therefore, we hope that this paper will be used as basic data to recognize the need for education on digital intraoral scanners.

This study recognized the mutual collaborative characteristics among consultants as important factors in the performance of the government-supported consulting business, and wanted to look at the impact of the cooperative characteristics among consultants on the consulting performance. First, a research model was presented based on theoretical background, hypotheses were set up and surveyed, and hypotheses were verified by multi-circulation analysis. Among the collaboration characteristics among consultants, the most influential was mutual reliable followed by smooth communication, professional competence and role sharing. information sharing was rejected and was found to be relatively less affected than other variables. This can be seen as more important than the quantitative aspect of information sharing because of the collaborative nature of consultants who must work toward common goals. Collaboration among consultants has been positive when carrying out government-funded consulting projects, suggesting that quantitative characteristics should be considered based on the qualitative characteristics based on mutual reliable. In the future, we hope that this data will be useful for identifying collaborative characteristics among consultants when carrying out consulting projects.
