Radioactive medicines are used a lot owing to the increase of a PET-CT examination using glucose metabolism useful for the early diagnosis of diseases. Therefore, the spatial dose that is generated from patients and their surroundings causes the patients' guardians and health professional to be exposed to radiation. However, they get unnecessarily exposed to radiation because medical institutions lack in space for isolation and recognition of the examination. This research intended to examine the spatial dose rates by measuring the dose emitted from the patient for 48 hours to whom F-18 FDG was administered. The spatial dose rates that were measured 100cm away from the patient's body after F-18 FDG was injected were $65.88{\mu}$Sv/hr at 60-minute point, $45.13{\mu}$Sv/hr at 90-minute point, $9.88{\mu}$Sv/hr at 6-hour point, and $1.24{\mu}$Sv/hr at 12-hour point. When the dose that the guardian and health professional got was converted into the annual(240-day working) accumulative dose, it was examined that the guardian received 81.56 mSv/yr and health professional received 49.36mSv/yr. In addition, the result has revealed that the dose that the patient received from one time of PET-CT examination was 3.75mSv/yr, which is 1.5 times more when compared with the annual natural radiation exposure dose.
This paper has examined a resident's feeling of satisfaction on residential environment. It has searched a policy direction to improve the quality of residential environment with three models in which what factors have an influence on the resident's feeling of satisfaction is evaluated. First, when the residents were asked why they chose lease APT, Low price was answered the most between two populations. Second, with regard to the feeling of satisfaction by categories, both populations showed similar results. The social prejudice on lease APT such as disadvantage on their children and unfavorable surroundings that has been engraved in people's mind about lease APT for a long time was never an issue any more. Third, when the two populations were examined by regression analysis with three models in terms of what factors had an effect on the feeling of satisfaction, there was no big difference in each effect of variables. Internal environment was a key variable for lease APT while external environment was a core variable for the APT that is converted into installment sale. In order to enhance the feeling of satisfaction on residential environment for lease APT residents, high quality turned out the most important factor between both populations, and then a loan with low interest rate and high average standard of APT followed. As unsatisfactory items, low cultural level, slowness in repairing works, and unsatisfactory finishing work were pointed out with regard to the low quality of internal facilities. In general, it turned out that the APT that was converted into installment sale was more preferable than lease APT. As known in this analysis, housing supply policy needs to be focused on quality and high average standard of APT should be achieved for the working classes.

New trend called ubiquitous leads the recent business by standardization and integration. It should be the main issue how to guarantee the integration and accountability on each business, especially in mission critical system which is mainly supported by M2M (Machine to Machine) control mechanism. This study is from the analysis of digital forensics case study that is from the M2M Sensing Control Mechanism problem of the "Imjin River" case in 2009, where a group of family is swept away to death by water due to M2M control error. The ubiquitous surroundings bring the changes in the field of criminal investigation to real time controls such as M2M systems. The needs of digital forensics on M2M control are increasing on every crime scene but we suffer from the lack of control metrics to get this done efficiently. The court asks for more accurately analyzed results accounting high quality product development design. Investigators in the crime scene need real-time analysis against the crime caused by poor quality of mission critical systems. It seems to be every need of Real-Time-Enterprise, so called ubiquitous society on the case. We try to find the efficiency and productivity in discovering non-functional design defects in M2M convergence products focusing on three metrics in study model with quick implementation. Digital forensics system in present status depends on know-how of each investigator and is hard to expect professional analysis on every field. This study set up a hypothesis "Co-working of professional investigators on each field will qualify Performance and Integrity" especially in mission critical system such as M2M and suggests "Online co-work analysis model" to efficiently detect and prevent mission critical errors in advance. At the conclusion, this study proved the statistical research that was surveyed by digital forensics specialists around M2M crime scene cases with quick implementation of dash board.

The current beauty service of Korea is upgrading its outside appearance from traditional small-shop image and its speed of change and competition are more severe than ever before. The top priority trait of beauty management is based on man-power resource, and personnel-management is the most important thing that more than anything else. Compared with other arenas of business, personnel management plays a key role in beauty industry. As a result, this research begins with the issue of personnel management. In addition, I will show that the management leadership of beauty service affects organization civil actions and changing jobs in the beauty industry employees, and the leadership can lower changing job rate to some extent. The role and duty of business manager is very significant because the dependence of man-power resource is magnificent in beauty service. In spite of rapid changing of economic surroundings, the management of beauty service is still working without any detail plans. It is no exaggeration to say that the most of beauty service managers are lack of leadership conception. Although the demands of customers are changing everyday, the frequent changing of jobs among talented employees drops customers credibility and high-quality service. From a management viewpoint, re-training cost of employees leads to economic loss and the company suffers from financial problems. As a result, it creates vicious circle in the beauty industry. Today, the management atmosphere in the beauty service is hard to get its right track because of the cutthroat competitions of beauty industry and difficulties of hiring promising employees. It has been said that "Nothing ventured, Nothing gained" Above all, the beauty service requires job speciality and it produces economic profits. Therefore, the managers desperately need to change the way they regard those with job changers. In this research shows the principal index of the leadership type of beauty business managers how much affects its employees' long-term working condition. The new concept of leadership, such as alternative suggestions, setting goals, and organization civil action will reorganize the stereo-type frame. I will also investigate the factors of job changing and intention of the beauty service employees for the development option of the beauty industry.
In July 1993 a new prescription of the EC was finished, concerning the voluntary participation of enterprises in a common auditing system. By this in the EC-member countries there must be founded centers of environmental auditing where experienced experts of environmental auditing should be accredited. These accredited experts are controllers for evaluating and certification of carried out environmental-auditings. An environmental-auditing practically represents an environmental assessment for an already existing enterprise with establishing corresponding programmes and strategies for the internal management to improve the environmental relations. Much experiences, which could be collected in the field of EIA during the last years may be transfered to this new task immediately. Only an essential difference there should not be overseen because of national legislation EIA in the defined cases must be carried out. By the EC-prescription carrying out an environmental-auditing for an enterprise is optional, it is recommended only. It was not introduced as a must. In spite of this fact because of the hard competition on the market there will be developed a pressure for the enterprises, to carry out such environmental-auditings. At present already a number of first projects in this direction can be seen, in the first line above all enterprises with the necessary economic power want to use this possibility, to gain better positions on the market. We have already gathered the first experiences in this field. We arranged corresponding contacts to several enterprises within the surroundings of Dresden. Within an opening discussion, where the project is explained and discussed with the management of the enterprise very detailed, the understanding, the readiness and the cooperation for the project are generated necessary prerequesits for the success of the whole work. By means of careful detail-work in collaboration with all departments and on all levels of the enterprise the total mass and energy-balances of the factory established and analysed. There are included also such ranges like material delivery, personal policy, public relations and sale as well as waste management. It is important that all people working in the factory have the feeling to be our partners, and not to have the impression to be checked or controled by an outside organization. This one of the most important factors of environmental auditing, in order to wake up and to develop a common interest on all sides. At the end of the environmental auditing there will be according to the prescription of the EC a catalogue of measures to do immediately, short time, mean time and long time for improvement of the environmental situation of the enterprise. All proposals are made in connection with a corresponding economic evaluation. These measures and programmes are declared as the environmental manual and are the basis for the work of the environmental management of the enterprise for the next three years. According to the EC-prescription, the enterprise with this environmental manual can get a corresponding certificate, which may be used for public relation purposes.
The universe has its order of yang and yin : all creation are continuously generated, grow and die, which is the results of the harmonious operation by yang and yin. Among all creation, the human is one of the samjae(three bases of the world, which are heaved earth, and man) and he is from the combined sukhi(a superior khi) of yang and yin. And human life itself is basically a condensed jonghyul (life blood) and at the same time it is only a transient joining of sadae(the four elements of earth, air, fire and water). Yang and yin, the two axes of the world, therefore. are the most crucial and fundamental concept to explain the generation and extinction of alt creation, to understand people in time and space. to find out the reality of human life as an organism, and, at last, to observe the state of human health. If so, what is the most essential idea in yang and yin\ulcorner It is taegeuk(chungkhi) or tao(of one yang and one yin). If the property of heaven and earth is kongon, taegeuk is a khi and tao a principle. And it can be said that a human body is merely a union of hyung and khi, that human life is an essence of sambo, jeongkhishin, that human health is a harmoninzed coordination of yang and yin because it is from the combined sukhi of yang and yin. Hyung. a vessel for sambo, jeongkhishin, is at the bottom and shin is on the top : the personality and the disposition of individuals differ according to their working. Thus. on the basis of the above discussion. the following can be offered as some suggestions for Korean Nursing Theory. Though human beings are part of Nature, they are the most eminent microcosm among all creation. So, as a subjet for nursing, a person should be understood with khijok kyoryu rather than with logical thinking, then mutual trust between the patient and the nurse can be established. The health of a person depends on the harmony of yang and yin. To be healthy, a person should consider harmonization with Nature(including his surroundings) as well as a balanced human relationships in society. Moreover, it is crucial for each person to obtain hoshim as a method of mind control rather than to only treat the symptoms of disease.
The purpose of this study was to describe how one woman became a science docent's exper and how she developed expertise in her field of work as a docent in science museum. A life history approach, one of the qualitative research methods was employed in this study. A docent Ms. Park, had her career as a docent for eight years and she was selected through the procedures as follows. The $1^{st}$ phase of selection, the researcher contacted 56 docents who were working using a convenience sampling method. In the $2^{nd}$ phase of selection, 11 of them were then selected on purpose for further study. Finally docent Paek was selected as a case for this study on the basis of her responses to survey questions and interviews as well as her willingness to participate. Research data were collected through mainly interviews, participant observations, and docents' artifacts. We analyzed data to reveal Ms-Park's life history of how she became a docent, how her work was as a docent, and what efforts she made to become an expert as a docent of science museum. Findings are as follows. First, docent Park demonstrated strong educational beliefs that influenced her field work, as the beliefs have continuously been formed throughout her life experiences. Second, she acquired and organized her practical knowledge of exhibit interpretation through real activities and experiences interacting whith visitors and demonstrating exhibits in science museums. Third, docent Park showed her ability to make full use of surroundings and resources available for developing her expertise on exhibit interpretation more effectively. With these findings in mind, we suggest that a well established docent system as well as its operation, and physical support be needed for increased docents' expertise and meaningful education in science museum.

This research was completed to provide fundamental data regarding the guidelines to installing and managing utility facilities & structures in wetland protected area to advance the functions and sustainable use of ecology services by preserving the ecology within wetland protected area. There were 5 on-site researching areas that were used as the main subject with these areas chosen and considered from 21 inland wetlands that have been designated and are being managed from the Ministry of Environment and by their designated dates as a wetland protected area. The utility facilities in these wetland areas were categorized by their types and a detailed on-site investigation was proceeded with investigation items chosen whereas these facilities are working by their roles from their location, size, used materials, types, information contents and etc., The results showed that regarding informational structures, several locations of information boards were distanced from the main exploring routes which did not consider the visitor's eye level which had their readability dropped and by sunlight, time lapse and water penetration, many information boards were damaged or corrupted so that it was hard to confirm the information noticed or understanding an image. Insufficient observation and educational structures were installed that considered the ecological characteristics of wild animals and their living conditions. Regarding convenience facilities, there were parking lots that were installed on the fore-land and to decrease non-point solution sources, some parking lots needed to be located in protected lowlands while some facilities' shape and colors did not harmonize with their natural surroundings, creating a sense of awareness, which will need some more consideration. As for safety facilities, they were very insufficient compared to other facilities. This means that additional safety structures are needed so that related personnel can be aware of where a visitor is located when an accident occurs. Protectional facilities strongly needed new structures and a management system to cut off entrances and do surveillance so that visitors do not go into areas outside of the managed areas and bring damages to restricted locations. Research labs needed to expand the use of automatic weather systems and water gauge equipments to build fundamental data regarding floodgates that are intimated to the forming of wetlands. Sensor cameras and other types of monitoring systems are needed to monitor the majority types of animals living in the wetlands as well.
The 1920s and 1930s ushered in "the golden age" of Chinese comics when the comics flourished. Satirical cartoons in modern Chinese comics were popular due to emotional instability and war caused by foreign powers. Among many popular comics, this paper analyzes in the 1920s and in the 1930s which were made into films and dramas. Chapter Two shows that China in the Republican era of China expanded its consumer culture into some sectors like films, novels, magazines and fashion in the 1920s and 1930s. However, more than any other things, this chapter considers from the historical perspective "the golden age" of comics including comic magazine in the 1930s and a history of comic magazines that gained popularity with conventional and common story. Chapter Three explains that social satire cartoons were in vogue since the May Fourth Movement and anti-imperialistic and semi-feudalistic stories in the 1920s were realized in life. It also says that comics that describes the negative sides of its society were popular. Ye QianYu, a cartoonist, portrayed many facets of Shanghai through : the daily life of the middle and lower classes, bureaucratic corruption and sympathy for the working class. drawn by Zhang LePing describes the unfair social system between the bourgeoisie and the proletariat and the gap between the rich and poor through the main character, the powerless and poor orphan. and lampooned the reality of its time in an objective, witty and humorous way in terms of ethics and economy respectively. The researcher chooses to study and which are very familiar to us, because good cartoons, animations and movies stimulate the feelings about our surroundings.

In this study, the natural ventilation pressure resulting from the large altitude difference which is a characteristic of high radioactive waste repository and the caloric value of the heat emitted by wastes was calculated and based on the results, natural ventilation quantities were calculated. A high radioactive waste repository can be considered as being operated through closed cycle thermodynamic processes similar to those of thermal engines. The heat produced by the heating of high radioactive wastes in the underground repository is added to the surrounding air, and the air goes up through the upcast vertical shaft due to the added heat while working on its surroundings. Part of the heat added by the work done by the air can be temporarily changed into mechanical energy to promote the air flow. Therefore, if a sustained and powerful heat source exists in the repository, the heat source will naturally enable continued cyclic flows of air. Based on this assumption, the quantity of natural ventilation made during the disposal of high radioactive wastes in a deep geological layer was mathematically calculated and based on the results, natural ventilation pressure of $74{\sim}183$Pa made by the stack effect was identified along with the resultant natural ventilation quantity of $92.5{\sim}147.7m^3/s$. The result of an analysis by CFD was $82{\sim}143m^3/s$ which was very similar to the results obtained by the mathematical method.
