It is revealed that there are more registered disabled people in our country who have their disability because of acquired factors such as accidents than because of innate deformity. This phenomenon will continue and the incidence of acquired disability will increase more and more. Even though there is noticeable change, the social recognition toward the disabled is still negative. Particularly, university students are in the early adulthood according to the development of life-cycle, and this is the period that people have diverse social relationships, depart from unified frame and work in various fields, and set up their own thoughts and ideology with knowledge and skills acquired from university education. Therefore, in this study, we are going to search the recognition of the university students, who are in the previous period of entering into the society, toward the disabled, and if they have negative prejudice or attitude against the disabled, we are going to find the ways to improve on their awareness positively. The subjects of the survey were randomly selected among 230 out of total 250 students by visiting thirteen universities in Chungcheong Province, and were analyzed by using SPSS (ver. 18.0) program. T-test and One-way ANOVA were used as analytical methods to look into the difference of analysis of frequency, descriptive statistic, reliability analysis and attitudes for comprehending sociodemographic characteristics of the subjects of the survey. In conclusion, it has to be not a temporary or event-like training, but a training that makes people have positive recognition and attitude towards accurate information, knowledge, human rights, disability, and diversity. This thesis has a limitation to be generalized to the university students all over the country since the region is limited to a certain area.

Display quality assessment has been a long standing issue due to the diversity of display devices and the rapid growth of display technology. The conventional display quality assessment methods are mostly those methods which evaluate qualities of a display by measuring physical quantities, but the results from the methods are not equal to the perceived results which are acquired with subjective experiments. Thus, we need to solve the above contrariety as well as establish the quantitative correlation between physical and perceived results. This paper proposes the systematic method of evaluating relative perceived qualities among various display devices and quantifies these relative perceived qualities. The proposed method is based on Analytic Network Process(ANP), which is one of the most popular decision making methods in the business administration field. We also adopted three evaluation criteria, which consist of color, shape and depth, in order to reflect the human visual system and chose eight sub-criteria related to display characteristics via question investigation. We carried out a subjective experiment and the proposed method which evaluated perceived qualities of two display devices(TFT-LCD, OLED) in order to prove the similarity between their results. As a result, it is proved that the order relationship between perceived qualities was the same as the order of results got through the subjective experiment.

This study is to develop digital leadership in a field of national defense. Today, korean society is facing the crisis of national security. But national defense leadership is not show in the circumstance of national security crisis. As you know, national defense leadership is a process that make use of influence. Which means it converges people's interest and demands well and also show people the right vision of national defense and make them to comply the policy about national security. Because of the environmental change, our national defense leadership is having a new turning point. First, international order, which is under post-cold war, raises possibility of guarantee of peace and security in international society but also, cause the increase of multiple uncertainty and small size troubles in security circumstance. In addition, Korean society is rushing into democratization and localization period by success in peaceful change of political power went through about three times. The issue of political neutralization of military is stepping into settlement but still, negative inheritance of old military regime is worrying about it. In this situation, we can't expect rise in estimation about the importance of security and military's reason for being. So, military have to give their concern to not only internal maintenance of order and control and growth of soldiers but also developing external leadership to strength influence to society and military's the reason for being. So for these alternative I'm suggesting a digital leadership of national defense which fits digital era. This digital leadership is the leadership which can accept and understand digital technology and lead the digital organization. To construct digital national defense we need a practical leadership. The leadership has to be digital leadership with digital competence that can direct vision of digital national defense and carry out the policy. A leader who ha s digital leadership can lead the digital society. The ultimate key to construct digital government, digital corporate and digital citizen depends on digital leader with digital mind. To be more specific, digital leadership has network leadership, next generation leadership, knowledge driven management leadership, innovation oriented leadership. A leader with this kind of leadership is the real person with digital leadership. From now on, to rise this, we have to build up human resource development strategy and develop educational training program.

The aim of the this study is to observer paradoxal phenomenon in media election. The media, especially Television, was traditionally a journalistic operation representing political events on the outside of political camp. But recently, it intervenes to 'the political camp' as the most important method for election campaign. A centripetal of electronic medias making the dominant political space offer an alternative plan which get over the modern crisis of representative democracy. Even though, to the production of the political symbol and the operation of symbol which constitute substantial system of political action, the human being subject is excluded and the technical system of communication make up a govern structure. So it makes the contradictory situation. TV broadcast for election campaigning show well this paradoxal situation. The institutionalization of electoral broadcasting oriented by the State strengthens an immensification, an economical and political efficiency and a transparency of electoral campaign. But the means which controls the mind of public is also strengthened. It relates the production and circulation of the political symbol and the symbolic image restricted by dominator. In conclusion, this study argues that the media election is institutionalized by the instrumental reason(procedural rationality of politics and technological rationality of broadcasting), therefore the candidate take a fragment roles for the production of transcendental political symbol and the voters accommodate to the symbolic images which are foreseen and they judge.

Purpose: In this study the present status of the practicum in Fundamentals of Nursing and test for student competency in nursing skills were surveyed. Method: Participants included 72 nursing schools. A structured questionnaire was used for data collection and SPSS 17.0 for data analysis. Results: Credits for Fundamentals of Nursing, credits for practicum and hours per credit were 2.93, 7.34, and 2.14 respectively. Number of students per practice unit, full time assistants and students per assistant were 28.6, 0.6, and 20.2 respectively. Utilization of CPX room and OSCE room for practice was 5.6%, and 9.7% respectively. Of the school, 32.0% included clinical practice in the practicum. 90.3% provided an open lab but only 48.4% had full-time assistants for these clinical practice areas. Testing for nursing skill competency was performed twice a semester in most schools. Utilization of standard patients and high fidelity models for testing was 8.3%, and 23.6% respectively. The test was thought to be inappropriate in 33.4% of the schools. Conclusions: The results suggest that to improve the outcomes, the practicum for Fundamentals of Nursing needs to be changed to include expansion of facilities and human resources, utilization of standard patients and high fidelity models and development of appropriate test methods.

This study analyzes the differences to examine which education is more effective for practical cooking skills. A survey was conducted on the 4 year university students majoring in culinary arts to examine the recognition levels of culinary practice education for the purpose of searching for an improvement plan for culinary education. The results are as follows. Seniors recognize the importance of learning theory, while the classes offered now are focusing on getting cooking certificates. The students approach cooking not only for eating food but also for the arts, showing increased interests in 'creative food' and 'fusion food.' In class, they feel the necessity of establishing a standard for a fair assessment and English skills for the globalization of food service. Hereupon this study recognizes the current state of culinary education service, draws factors which decide the quality of culinary arts education, and examines student satisfaction with theoretical education, practical education, assessment, and external education by using a factor analysis of twenty quality attributes. Through the development and application of various programs, operation of open practice classes and culinary organization reflecting social changes in learning courses, the culinary arts education is considered to be more vitalized. In this respect, this study introduces four measures which were designed to facilitate the education of highly-skilled human resources in the culinary field.

Purpose: The purpose of this work is to describe the spectrometric analysis of gaseous cloud formation over reactor mixed uranium-and-plutonium (UP) fuel $(U_{0.8}Pu_{0.2})O_2$ samples heated to a temperature $>2,000^{\circ}C$, and thus forecast and evaluate radiation hazards threatening humans who cope with the consequences of any accident at a fission reactor loaded by UP mixed oxide $(U_{0.8}Pu_{0.2})O_2$, such as a mixture of 80% U and 20% Pu in weight. Materials and methods: The UP nuclear fuel samples were heated up to a temperature of over $2,000^{\circ}C$ in a suitable assembly (apparatus) at out-of-pile experiments' implementation, the experimental in-depth study of metabolism of active materials in living organisms by means of artificial irradiation of pigs by plutonium. Spectrometric measurements were carried out on the different exposed organs and tissues of pigs for the further estimation of human internal exposure by nuclear materials released from the core of a fission reactor fueled with UP mixed oxide. Results: The main results of the research described are the following: (1) following the research on the influence of mixed fuel fission products (radioactive isotopes being formed during reactor operation as a result of nuclear decay of elements included into the fuel composition) on living organisms, the authors determined the quantities of plutonium dioxide ($PuO_2$) that penetrated into blood and lay in the pulmonary region, liver, skeleton and other tissues; and (2) experiments confirmed that the output speed of plutonium out of the basic precipitation locations is very small. On the strength of the experimental evidence, the authors suggest that the biological output of plutonium can be disregarded in the process of evaluation of the internal irradiation doses.

This study examined the effects of estrogen, progesterone and tamoxifen at different concentrations and treatment periods on proliferation of a human cervical carcinoma cell line, HeLa, in culture, based on MTT assay. Estrogen did not have an effect on the cellular proliferation in concentrations up to $1{\mu}g$/ml for treatment periods of between 2.5 and 6 days, but significantly inhibited proliferation at a higher concentration of $10{\mu}g$/ml in a progressive manner with increasing treatment periods. Also, treatment of HeLa with more than $10{\mu}g$/ml of progesterone for 2.5 days significantly inhibited proliferation and caused a concentration-dependent inhibition with 4 days of treatment. However, longer treatment with progesterone for 6 days abolished the concentration-dependent inhibitory effect on cellular proliferation observed with the 4-day treatment period. Furthermore, tamoxifen required a higher concentration ($100{\mu}g$/ml) than estrogen to bring about the inhibitory effect on the HeLa proliferation. These results suggest that high concentrations of estrogen, progesterone and tamoxifen may suppress proliferation of HeLa, and both the concentration and the treatment period may also influence their inhibitory effects on cellular proliferation.

Human skin is constantly exposed to ultraviolet (UV) radiation, polluted air, and chemical products. UV rays, in particular, will affect the skin in a variety of ways, including causing wrinkles, fine lines, rough skin, and xeroderma, thereby resulting in skin aging. This study aimed to investigate the whitening effects of Juniperus rigida Sieb., which is a cedar tree that is found throughout the world. The whitening efficacy that was measured by tyrosinase inhibition revealed 49.4% efficacy in water extract and 80.0% efficacy in ethanol extract. Among the B16F10 black cells, the effect of the ethanol extract was higher than the effect of the water extract in the restrain creation of melanin pigment, tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase related protein-1 (TRP-1), and tyrosinase related protein-2 (TRP-2). Thus, the results of these studies demonstrated that the ethanol extract had greater efficacy than the water extract and Juniperus rigida Sieb. Ethanol extracts could be utilized as materials for functional cosmetics, such as whitening products.

This study was aimed for bettering productivity and technical level of the dental 1 aboratory, and helping the dental technician's benefits and rights, and then endowing them some belonged atmospher and stability on their post by Improving job- satisfaction and maintaining the transferability of one's post at a proper limitation. Therefore, 320 dental technicians extracted randomly from all the technicians working at 494 dental laboratories were subjected for this study. The approach to the study was a way through some postal questionaires executed from March 29, 1988 until May 4, the same year, in which total 254 technicians answered, showing 79% resp"nserate. responserate. The data-analysis was done by a model of the dental technician's transferability from their post, as considering Mobley's(1978)-model of post-transferability, and results through the study are as follows : 1. Satisfaction at a given post showed that the married is better than the unmarried(<0.05), and the experienced is better than the inexperienced(P<0.01). 2. Age, sex, educational experience, and one's service-duration did not affect significantly to the respondent's satisfaction on their post, statistically. 3. Satisfaction at a given post differed in adccordance with given conditions of one's post, i. e.,it stowed high when the monthly payment was good(P<0.05), and when too much duty on their job was given, it was the worst as shown in an example of the next order, too much
