The increase in size and numbers of general hospitals in the process of conspicuous development of modem medicine has been accompanied by a serious increase in hospital acquired infections. Hospital aquired infections cause pain and discomfort, may threaten life, adds an economic burden, and delays recovery and return to society. Even though respiratory hospital infection rates resulting for tracheostomy and respiratory inhalation therapy, may be low, they are serious because of their bad prognosis and high mortality rates. This study was designed to assess certain aspects of respiratory infections of patients with a tracheostomy and thus provide baseline data for further research related to preventive or therapeutic nursing interventions. The specific objectives were to determine the incidence of colonization in the trachea, clinical signs, type of colonized bacteria and sensitivity to antibiotics. Data were collected from July 1 to December 10, 1989 at two university Hospital in Seoul. Subjects were 20 patients with a tracheostomy admitted to the Intensive Care Unit or Cerebral Vascular Accident Center. Clinical signs related to respiratory infection were observed using a checklist based on previous study outcomes. Bacterial culture, sensitivity test to antibiotics, WBC counts and chest X-ray were also performed. Cultures were done on the day of tracheostomy, and on the third, fifth and seventh day. Cultures were then done on seventh days after the first colonization. The results were as follows : 1. The incidence of bacteria colonization in a week was 90%(18 patients) 50% (10/20 patients) on the day of tracheostomy, 70%(7/10 patients) on the third day, and 0% on the fifth day, and 33%(1/3 patient) on the seventh day. 3 of 18 patients (16.7%) were colonies of mixed growth isolated. 2. The observed clinical signs related to respiratory infection were high fever 38.9%(7 patients), prulent secretion 16.7%(12 patients) and infiltration seen on chest X-ray 33.3%(6 patients). 3. The total number of types of bacteria isolated among the 18 subjects was 21 ; gram negative 71.4%, gram postive 28.6%. The dominant bacteria type was Staphylococcus aureus(5 cases) for gram(equation omitted) and Pseudomonas aeruginosa(3 cases), Klebsiella (4 cases), Enterobacter(3 cases) for gram (equation omitted). The results of culture on 7th day after the first colonization, 6 cases showed same type of bacteria, 3cases showed different type of bacteria and 1 cases showed no growth. 4. The sensitivity tests to antibiotics showed that Pseudomonas aeruginosa and Staphylococcus were strongly resistant to most kinds of antibiotics, but Klebsiella and the rest of gram negative bacteria were moderately sensitive to antibiotics.

This research was performed to identify the characteristics of the Korean rituals and to establish the desirable ritual culture. The recognition of the ritual culture was investigated by the general environmental factors such as gender, age, religion and education background. The rituals were generally recognized as positive. Some significant differences were shown according to religion, gender and residential area. To succeed the tradition of the preparation and the table-setting of ritual foods and to conduct the rituals by the descendants were recognized relatively high by the Buddhists and males living In Gyeongsangbuk-do. The degree of recognition of the method of table-setting of ritual foods was higher if one was married and older, with Buddhism and the oldest daughter-in-law in a family. As above, the culture of Korean rituals showed some differences according to the general environment and regions of the individual. The reason why regional differences were shown high was mainly because tradition and conservatism were maintained according to the unique regional thought and natural environment rather than impacts of the changes of times. That some differences were shown according to general environmental factors suggested that the traditional ritual culture was gradually changing according to the environmental changes in the modem times. Also, the recognition on the ritual culture were identified through investigations by general environmental factors such as gender, age, religion and education background.

Recently the CPU performance of modem chipsets or multimedia processors of mobile phone is as high as notebook PC. That is why mobile phone has been emerged as a leading ICON on the convergence of consumer electronics. The various applications of mobile phone such as DMB, digital camera, video telephony and internet full browsing are servicing to consumers. To meet all the demands the image quality has been increasingly important. Mobile phone is a portable device which is widely using in both the indoor and outside environments, so it is needed to be overcome to deteriorate image quality depending on environmental light source. Furthermore touch window is popular on the mobile display panel and it makes contrast loss because of low transmittance of ITO film. This paper presents the image enhancement algorithm to be embedded on image enhancement SoC. In contrast enhancement, we propose Clipped histogram stretching method to make it adaptive with the input images, while S-shape curve and gain/offset method for the static application And CIELCh color space is used to sunlight readability enhancement by controlling the lightness and chroma components which is depended on the sensing value of light sensor. Finally the performance of proposed algorithm is evaluated by using histogram, RGB pixel distribution, entropy and dynamic range of resultant images. We expect that the proposed algorithm is suitable for image enhancement of embedded SoC system which is applicable for the small-sized mobile display.

As the 21st century began, cement and concrete that are representatives of modem building materials became a major factor in global warming, air pollution and environmental pollution. Also, the problems that are generated while pursuing high performance and high strength became social issues. Therefore, it has become urgent to prepare counter plans. This study has aimed at the recycling of sewage sludge ash and developing it as a new concept in building material which serves the environmental considerations for long-lasting developmental purpose. Also, the study aimed to find a substitute for scarce natural resources and to secure high techniques for waste recycling. The purpose of this study was also to solve fundamentally secondary environmental pollution. The results revealed that the chemical components of sewage sludge ash are mainly $SiO_2\;and\;Al_2O_3$ which are similar to the components of pozzolan. Also, it was identified that sewage sludge ash can be utilized as a hardened specimen with an alkali activated pozzolan reaction. Considering the possibility of appropriate strength development and the advantage of drying shrinkage, compared with that of cement, it was believed that sewage sludge ash can demonstrate a function as a substitute for cement given.

The purpose of this paper is to examine the common characteristics of late 20th century interior design style and the post-modern thinking system. A period has its own predominant spirit which determine the tendency of art, and the ubiquitous power in the spirit decides the period's pattern of art. Therefore the interior design style belongs to general art sphere that has its own individual character derived from the dominant power of the controlling system. Paying special attention to this understanding, the auther has processed this paper by combining the post-modem thinking with special characteristics of each of the 20th century interior design style. Until now, researches have been focused on the individual style of post-modern design; however, a general research comprising the whole characteristics of expression has not been made. Accordingly, the rationale of emphasizing the general point of view is establshed. Also, this study suggests a model applicable to studies concerning other art area. This type of methodology is receving more attention as an approach investigating new art ideology for researching post-modern thinking and late 20th century art styles. The conclusions are as follows: First, the distinctive expressions of postmodernism appear to be characteristic of illusion, metaphor, pluralism, decoration, and symmetry, Those of late modernism appear to be the characteristic of complicated simplicity and symplified complexity, passiveness of symbolism and harmony, indeterminacy of form and space, and unintentional decorativeness. And the characteristics of deconstructionism are spatial difference and temporal defferal, and un-reductive and non formal abstractiveness of the space, unfinishness, chance, and secretiveness of individual style. Second, the disinctive expression seems to share common characteristics with postmodern thinking. The best examples are pluralism, non-formalism, populism, and historicism, originating from the deconstruction of 'meta-narrative'. Third, based on the second conclusion, general distinctive expression could be simplified as chacteristics of plurality, hybridity, and indeterminacy. These expressive chacteristics appear to be automatically connected with general postmodern thinking. Last, in consideration of the above conclusion, the extreme generality could be distinctively clarified as 'textural co-exsistence'. Accordingly, the author might confirm that 'textural co-existence' originated from the text that comes from postmodern thinking. In conclusion, design expression of late 20th century interior design accepts the ?universal theme of ubiquitous postmodern thinking. And universal expressions and supreme generality can be common analysis tools for understanding and studying complicated late 20th century interior design.

Dongrae-bu, the administrative central area in Busan in Chosun-dynasty(1392-1910), performed the large parts of diplomatic and trading functions with Japan because of its geographical conditions. Because of his location, landscape of Dongrae city-wall is the mirror of political and military meaning in Chosun-dynasty period. Elements of landscape, such as site of city-wall, location and morphology of gates, government official buildings and the road systems can be interpreted by the functional and socio-cultural terms. The changes of landscape during Japanese colonial period(1910-1945) show that destruction of city-walt went on for the purpose of imperialism. Especially, the landscape which had political meaning in Chosun-dynasty had erased in terms of modem urban planning. Cates of city-wall, official guest house, fortress which symbolize the governing and political power of Chosun-dynasty were destructed almost perfectively. New road system was imported Urban planning was effective instrument through which city-wall could be destroyed for the Japanese colonialism. Under those processes, traditional structure was changed towards the dependency on Japan. Those relict landscape are remained in present urban landscape such as road system, cul-de sac, house and cornerstones. Those results of this study show that city-wall in Korea should be studied in terms of socio-cultural aspects in each periods.

Purpose : The purpose of this study was to identify hospice volunteers' perception of the death. Methods : This study was conducted with 327 adults who registered for the hospice volunteer education program in Severance Hospice Center from 1996 through 1999. The 4-years data was collected through a self-reporting questionnaire constructed and revised by the authors. The questionnaire was classified into 5 categories. The data collected were analyzed using SPSS/W. Results : 1) Hospice volunteers were mostly female(93.9%) with an average age of 48 years. The majority(82.6%) of the participants were Protestant. 2) From the 4-years data over 90 percent of participants thought of death as a process of life and responded positively to these three items : 'Death is a temporary separation from family', 'I will die in peace', 'Faith in God results in a freedom from fear of death'. 3) Age were statistically relevant to the following items: 'I often read the obituaries in the newspaper', 'Dying is a tragedy', and 6 items were significantly related to religion: 'I rarely think of dying unexpectedly', 'Death is a temporary separation from family'. 'Dying is a tragedy', 'We have to do our best to prolong life by use of modem medical technology', 'I feel comfortable thinking of death and dying, 'Faith in God results in a freedom from fear of death'. The finding that religiosity was related to perception of death is consistent with other reports. And $40{\sim}50$ year old Protestant women had more positive perception of death than $20{\sim}30$ year old women. Conclusion : The findings indicated an importance of considering the age and religiosity when we educate the hospice volunteers. And that will be a important basic-data to develope program for hospice volunteers.

Normally, aero photography using UAV uses about 430 MHz bandwidth radio frequency (RF) modem and navigates and remotely controls through the connection between UAV and ground control system. When using the exhausting method, it has communication range of 1-2 km with frequent cross line and since wireless communication sends information using radio wave as a carrier, it has 10 mW of signal strength limitation which gave restraints on life my distance communication. The purpose of research is to use communication technologies such as long-term evolution (LTE) of smart camera, Bluetooth, Wi-Fi and other communication modules and cameras that can transfer data to design and develop automatic shooting system that acquires images to UAV at the necessary locations. We conclude that the android based UAV filming and communication module system can not only film images with just one smart camera but also connects UAV system and ground control system together and also able to obtain real-time 3D location information and 3D position information using UAV system, GPS, a gyroscope, an accelerometer, and magnetic measuring sensor which will allow us to use real-time position of the UAV and correction work through aerial triangulation.

The study is to examine the concept, origin, developmental process, and characteristics of 'Kioonsangdong,' or 'lively energy' to look into whether 'Kioon' maybe interpreted by modern sense and sensitivity and be applied to contemporary creative activities, and to explore whether the ideality of 'Kioon' may be transferred into visualization in pictures. The article defines the scope of 'Ki' as 'Ki(energy)' of artistry and sees the Wei, Chin and the South & North dynasties as its derived point. In Chapter I, before the examination of 'Kioon,' 'the relationship of Ki and Oon,' and 'interrelationship of Kioon (energy) and Sangdong (liveliness) are investigated. It is impossible to define Kioon in a word due to its being abstract. Thus, although it does not seem to be unlimited, focusing on putting a variety of concepts of Kioonsangdong in order, it classifies the subject, from which such Kioon reveals itself, into 'its former self,' things of the object,' 'character,' and 'brush and Chinese ink.' Then, with selected representative works for each category, it examines how Kioonsangdong is reflected in the works. In addition, it comprehensively argues on Kioon through presenting the points of Kioon theories by many an art critic and artist from the Wei, Chin and the South & North dynasties to modem China. In Chapter II, the study analyzes the Kioon-reflected works that have been examined in Chapter 1 in the light of the Kioon theories of 'blanks,' 'styles of brushmanship,' and 'techniques of Chinese ink,' and by selecting and analyzing representative artists and works in each era, it investigates how Kioon had been transformed as times had changed. In Chapter III, which is the core of the study, is on contemporary interpretations of Kioon. I intend to interpret Kioon as scent. In other words, through replacing abstract Kioon with the olfactory sense, actually realizing and forming it, and then visualizing it onto my own work, I attempt to grope for contemporary interpretations of Kioon. That is to say, I explain how Kioon is transformed into scent on the grounds that the origins of Kioon may be detected in literature and aesthetics. Besides, the study looks into the process that 'the scent of the olfactory sense' turns into 'the scent of art,' which I assert by contemporary interpretations, and shows in details that it may be visualized in pictures presenting quotes. In Chapter IV, it analyzes Kioonsangdong expressed visually as the scent of art in my own work in terms of the three techniques of blanks, brushmanship, and Chinese ink.

In the early 20th century, the efforts for design standards for industry and the new aesthetic of Functionalism began from the Deutcher Werkbund, an English German Association of Craftsmen. In the similar vein, the Bauhaus, founded in 1919 at Weimar, provided the definition of Good Design, as a contemporary concept, that combines art with technology. From 1950 to 1955, the modern usage of the term 'Good Design' was derived from a series of exhibitions and consumer education programs conducted by the MOMA(Museum of Modern Art, New York). The mission was to bring modern design to the attention of the general public. From the second half of the 20th century, many specialists in different areas, such as designers, manufacturers, enterprises, and scholars, began to give various definitions of 'Good Design'. That's why it could be interpreted and applied to unique and various methods by them. Meanwhile, Rams and Norman argued that the Good Design has to be not only considered within function, aesthetic, technology, etc, but also interpreted from both the physical and psychological point of views. Accordingly, this study tried to find out the historical investigation and the definition of Good Design in detail, and to figure out that the user-centered design from both physical and psychological approaches is eventually synonymous to 'Good Design'.
