Hybrid video call healthcare system that we propose in thesis is a service for powerless people rather than ordinary people. This system is for communication between users and protectors(or volunteers). To reduce the underprivileged through the 'Malbeot Nanumi' is the purpose of the system. Hybrid Health Care System using a video call and temperature/humidity/pulse sensors that we propose in thesis can connect sensors with software, and save p2p connection information for 'Malbeot Nanumi' service by database. And health check data can save locally. Hybrid Health Care System in a Wireless Network Environment is a system that elderly people living alone is to be a conversation. The purpose of this thesis is to develop the software and to design a convenient UI to the user, And increasing consumption of care system by increasing the happiness index and increasing aging population.

Act of journalism is act of social practice. Therefore, judgment on its rightness must be a prerequisite. That is why journalism requires philosophy. Barrenness of journalism philosophy promotes journalism to serve only as an instrument. No power and money should intrude the essential philosophy of journalism. Journalism must secure its own value. Remaining silent when its fundamental value is at risk is to negate one's own value of existence. It is self-denial. Social practice of journalism is assurance and realization of its essential value. Thus, it is historical. It is the juncture of journalism and history. Journalism without history leads to barrenness in philosophy. Without philosophy, journalism thus cannot uphold its historical mission. Journalism philosophy becomes a reality through the history. Concrete journalism philosophy shall come to light through historical reality. That is why conversation between journalism philosophy and journalism history is necessary. Thus, this research investigates how journalism philosophy formulates and reconstructs itself within journalism history. At the same time, this research thoroughly examines how journalism philosophy concretizes in journalism history, how historical subjects have practiced journalism and how all these have projected themselves in journalism history.

Since microgravity survey aims to delineate subsurface density structures in small scale, it requires inversion method, which is able to resolve small scale structures. It can be achieved by adopting a stabilizing functional which separates density boundary distinctly, which is different concept from general inversion routines. We composed Matlab-based interactive two-dimensional microgravity data inversion package containing several kinds of inversion routines with different stabilizing functional, for handling various geologic conditions and survey purposes. Different kinds of inversion routines in the package were verified and examined with representative synthetic data sets generated by numerical modeling. In addition, we applied the developed package to a real microgravity survey data.

Using data from 2011 Elderly Living Condition Survey database, this study analyzed risk factors for suicide ideation of Korean elderly persons. The analysis sample consists of 10,003 cases. The main purpose of this research was to explore the effects of social quality factor on suicide ideation of Korean elderly persons. Analysis results show that gender, age, area of residence, living alone, subjective standard of living, activities of daily living(ADLs), and geriatric depression are significant predictors of suicide ideation. Key findings are that social quality factor such as experiencing feeling hurt from others' words and actions like avoiding conversations, disregarding one's opinions, pretending to be not heard, getting irritated, grumbling, etc. has the largest effects on suicide ideation. Analysis results imply that without improving social quality, it would not be possible to lower elderly suicide rate.

This study investigated mentor teachers' mentoring types and how the types of mentoring changed throughout the collaborative mentoring program for beginning science teachers who had difficulties in teaching practice. One-on-one mentoring meetings were audio-taped and transcribed for analysis. The result of the study showed that mentors took various roles such as Observer, Critical friend, Provider of feedback, Instructor, Role model, Evaluator, Counselor, and Equal partner. However, if mentoring did not bring about a change in the perception of a science instruction of a mentee teacher, there was no positive change in the teaching of the mentee teacher. Therefore, mentor teacher must have enough time to concretely discuss about mentee teachers' perception of a science instruction, mentoring method, etc. with mentee teacher before mentoring.

The purpose of this study is to analyze the life stress factors and the changing eating behaviors of the students. We selected a dental hygiene college in Seoul and Daejeon and surveyed 387 students with email and self-administered questionnaires. The studying(3.16) of the stress factors was the most contributing factor followed by career path 3.04, economic 2.97. Regarding differences in each life stress factors according to general characteristics, they were found statistically significant to Body mass index, economic condition, family conversation time and self recognition of health status. Results showed that 39.7% of students ate snacks 1 to 3 times per week, 44.0% preferred spicy flavors after stress, 47.7% ate more than usual after stress, also among the group with high stress was revealed bad results of eating behaviors. According to this study, we identified the factors that affect the daily stress of dental hygiene students and the consequent changes in eating behavior and the results will be consulted on the training and counseling to adjust to college life.

To join the leading four countries in high speed railway technology, the next generation high speed railway technology development project is undergoing. And, applying the IT for the safety and convenience of a passenger and an attendant is one of the research topics of the project. From the 24 derived candidate IT applications, the seven applications, such as information on an individual LCD monitor, an emergency or reminder notification, an Internet connection, remote communication with an attendant, air quality monitoring, extraordinary noise detection, and detection of an emergency in the lavatory, were selected to be implemented on the next generation train. In this paper, we presented the survey that was performed to make the selection process to be objective. Additional findings, such as what other services a passenger wishes to be provided, what activities passengers prefer to do based on duration of the trip, and things that make a passenger discomfort, were summarized.

XML can effectively express structured or semi-structured data as well as relational databases. XQuery is a query language for retrieving information for such an XML document. In this paper, an XQuery composer is designed and implemented, with an API provided for XQuery processors, and a proper processor is registered. This composer shows query results immediately processed by the processor. As this composer contains a parser for XQuery, it can compose XQuery effectively using a diverse dialog box designed for XQuery grammar. A dialog box is affiliated with a clause region, which is a region that algebra operates from the parsing tree. It can compose path expressions for an XML document easily as it shows an element tree from DTD graphically. Path expressions are composed automatically by marking elements in the structural hierarchy and by specifying the predicate of an element partially.

This paper discusses the optical system design for projection TV using LCOS type micro display, which provides the high resolution, slim depth, and a large screen of more than 60 inches. We analyzed the relationship between the illumination system, projection lens, color separation & recombination system, and micro display. From this quantitative analysis, the starting data for the optimum light engine was defined, and all optical systems were designed by an optimization process. Three RGB panels were proposed for a high luminence system, and the four prisms symmetrically located make equal optical path lengths for the RGB rays. This color separation & recombination system enables the a compact illumination system. Also, in order to the slim light engine with high resolution, the folded projection lens system was designed by inserting a mirror between projection lenses.

This article aims at developing Mind Healing Program for university students, whose anxiety and depression are getting serious. Reality therapy was experimented total 10 times(one time per week), which was the revision and supplement of Woo(1994)'s reality therapy program. It consists of introducing program and self, understanding 5 mind desires, identifying obstacles of conversation, learning efficient communication skills, controling irrational expectation of others, recognizing mind gap, problems of choice and responsibility, nurturing mind, etc. The effectiveness of this program was verified through a model whose research variants were participation motivation, participation satisfaction, and mental health. Direct effects of participation motivation, participation satisfaction, and mental health were less satisfactory than indirect effects of the time when program satisfaction is a variant. It is concluded that mental health of participants is getting better when more satisfactory program should be provided, rather than motivation of simple participation.
