  • A gas chromatography-mass spectrometric (GC-MS) assay method was developed for the rapid and sensitive determination of volatile- and semivolatile organic compounds in water. Two hundreds mL of water sample was extracted in a 250 mL separatory funnel with 1 ml of pentane at pH 6.5. Fluorobenzene and 1,2-dichlorobenzene-d4 as internal standards were added to water sample and the solution was mechanically shaken for 5 min and analyzed by GC-MS (selected ion monitoring) without more any concentration or purification steps. The peaks had good chromatographic properties and the extraction of these compounds from water also gave relatively high recoveries with small variations. The range of detection limits of the assay was 0.5-10 ng/L. Turnaround time for up to about 40 samples was one day. This method is simple, convenient, and can be learned easily by relatively inexperienced personnel. This method was used to analyze 15 volatile- and semivolatile organic compounds in water of a Lake, and raw and treated water from three Water Treatment Plants in Korea. As the analytical results, benzene, toluene, xylene, isopropylbenzene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, naphthalene and 2,4,6-trichlorophenol were detected at concentrations of up to 0.4, 1.9, 1.3, 0.2, 1.8, 13.0, 1.7 and $1.1{\mu}g/L$, respectively. But chlorobenzene, trichloroethylene, tetrachloroethylene, ethylbenzene, n-butylbenzene and dibromochloropropane levels during that period were not significant. The removal effect of the compounds in three Water Treatment Plants was calculated. The compounds studied were generally removed during conventional water treatment, especially during the active carbon filtration.

  • The purpose of the study is to develop the indicator and scale for evaluating the service environments of archives and to assess the physical service environments of National Archives of Korea (NAK), and then to suggest the alternatives to improve the current service environments on the basis of the results of evaluation. To achieve the purpose, the study designed three research phases: first, to develop the indicator and scale to measure the current service environments by merging universal design indicators and various standards of NAK for establishing facilities and environments on the basis of the barrier-free authentication indicators; second, to evaluate the current service environments of NAK with the newly developed scale; finally to suggest alternatives to improve the current environments on the basis of the evaluation findings. The study found that current service environments of NAK have critical limits on the areas and facilities to provide direct archival information services to users such as reference service desks, showrooms, education rooms, seminar rooms, etc. On the basis of the results, the study suggested the alternatives and further studies for making barrier-free service environments of archives.

  • This study analyzed the operation status of the military library and e-book service in order to improve the soldiers' access to the reading environment and to suggest a plan to revitalize the military library. As a result of the survey, it was found that it is necessary to improve the environment such as the IT environment, devices, and time allowed for access to activate the use of e-books. According to the interview results, problems such as low usage rate and awareness of the digital library, the use of different e-book viewers and management systems for each distributor when distributing e-books, and the dissemination of e-books for the management and accessibility of the Armed Services Editions in library were raised. In order to activate the e-book service of the library in the military, diversify e-book service promotion and education programs, activations such as establish standards for the e-book operating system for each county, use platforms and devices to promote e-book operation and use, and construction of e-book service using Armed Services Editions were derived.

  • Learning progressions (LP), which describe how students may develop more sophisticated understanding over a defined period of time, can inform the design of instructional materials and assessment by providing a coherent, systematic measure of what can be regarded as "level appropriate." We developed LPs for the nature of matter for grades K-16. In order to empirically test Korean students, we revised one of the constructs and associated assessment items based on Korean National Science Standards. The assessment was administered to 124 Korean secondary students to measure their knowledge and submicroscopic representations, and to assign them to a level of learning progression for the particle nature of matter. We characterized the level of students' understanding and models of the particle nature of matter, and described how students interpret various representations of atoms and molecules to explain scientific phenomena. The results revealed that students have difficulties in understanding the relationship between the macroscopic and molecular levels of phenomena, even in high school science. Their difficulties may be attributed to a limited understanding of scientific modeling, a lack of understanding of the models used to represent the particle nature of matter, or limited understanding of the structure of matter. This work will inform assessment and curriculum materials development related to the fundamental relationship between macroscopic, observed phenomena and the behavior of atoms and molecules, and can be used to create individualized learning environments. In addition, the results contribute to scientific research literature on learning progressions on the nature of matter.

  • The National Defense Reformation bill of "National Defense Reformation 2020" which have been constantly disputed and reformed by the government went through various levels of complementary measures after the North Korean sinking on the Republic of Korea (ROK) Naval Vessel "Cheonan". The final outcome of this reform is also known as the 307 Plan and this was announced on the 8th March. The reformed National Defense Reformation is to reduce the number of units and military personnel under the military structure reformation. However, in order for us to undertake successful National Defense Reformation, the use of privatized civilian resources are essential. Therefore according to this theory, the ROK Ministry of National Defense (MND) have selected the usage of privatized resources as one of the main core agenda for the National Defense Reformation management procedures, and under this agenda the MND plans to further expand the usage of private Especially the MND plans to minimize the personnel resources applied in non-combat areas and in turn use these supplemented personnel with optimization. In order to do this, the MND have initiated necessary appropriate analysis over the whole national defense section by understanding various projects and acquisition requests required by each militaries and civilian research institutions. However for efficient management of privatized civilian resources, first of all, those possible efficient private resources which can achieve optimization will need to be identified, and secondly continuous systematic reinforcements will need to be made in private resource usage legislations. Furthermore, we would need to consider the possibility of labor disputes because of privatization expansion. Therefore, full legal and systematic complementary measures are required in all possible issue arising areas which can affect the combat readiness posture. There is another problem of huge increase in operational expenses as reduction of standby forces are only reducing the number of soldiers and filling these numbers with more cost expensive commissioned officers. However, to overcome this problem, we would need to reduce the number of positions available for active officers and fill these positions with military reserve personnel who previously had working experiences with the related positions (thereby guaranteeing active officers re-employment after completing active service). This would in tum maintain the standards of combat readiness posture and reduce necessary financial budgets which may newly arise. The area of maintenance, supply, transportation, training & education duties which are highly efficient when using privatized resources, will need to be transformed from military management based to civilian management based system. For maintenance, this can be processed by integrating National Maintenance Support System. In order for us to undertake this procedure, we would need to develop maintenance units which are possible to be privatized and this will in turn reduce the military personnel executing job duties, improve service quality and prevent duplicate investments etc. For supply area, we will need to establish Integrated Military Logistics Center in-connection with national and civilian logistics system. This will in turn reduce the logistics time frame as well as required personnel and equipments. In terms of transportation, we will need to further expand the renting and leasing system. This will need to be executed by integrating the National Defense Transportation Information System which will in turn reduce the required personnel and financial budgets. Finally for training and education, retired military personnel can be employed as training instructors and at the military academy, further expansion in the number of civilian professors can be employed in-connection with National Defense Reformation. In other words, more active privatized civilian resources will need to be managed and used for National Defense Reformation.

  • The study was aimed at developing an independent hospice center model that would be best suited for Korea based on a literature review and the current status of local and international hospices. For the study, five local and six international hospice organizations were surveyed. Components of the hospice center model include philosophy, purpose, resources (workers, facilities, and equipment), allocation of resources, management, financial support and hospice team service. The following is a summary of the developed model: Philosophies for the hospice center were set as follows: based on the dignity of human life and humanism, help patients spend the rest of their days in a meaningful way and accept life positively. On the staff side, to pursue a team-oriented holistic approach to improve comfort and quality of life for terminally ill persons and their families. The hospice center should have 20 beds with single, two, and four bed rooms. The center should employ, either on a part-time or full-time basis, a center director, nurses, doctors, chaplains, social workers, pharmacists, dieticians, therapists, and volunteers. In addition, it will need an administrative staff, facility managers and nurses aides. The hospice should also be equipped with facilities for patients, their families, and team members, furnished with equipment and goods at the same level of a hospital. represented by a center director who reports to a board and an advisory committee. Also, the center director administers a steering committee and five departments, namely, Administration, Nursing Service, Social Welfare, Religious Services, and Medical Service. Furthermore, the center should be able to utilize a direct and support delivery systems. The direct delivery system allows the hospice center to receive requests from, or transfer patients to, hospitals, clinics, other hospice organizations (by type), public health centers, religious organizations, social welfare organizations, patients, and their guardians. On the other hand, the support delivery system provides a link to outside facilities of various medical suppliers. In terms of management, details were made with regards to personnel management, records, infection control, safety, supplies and quality management. For financial support, some form of medical insurance coverage for hospice services, ways to promote a donation system and fund raising were examined. Hospice team service to be provided by the hospice center was categorized into assessment, physical care, emotional care, spiritual care, bereavement service, medication, education and demonstrations, medical supplies rental, request service, volunteer service, and respite service. Based on the results, the study has drawn up the following suggestions: 1. The proposed model for a hospice center as presented in the study needs to be tested with a pilot project. 2. Studies on criteria for legal approval and license for a hospice center need to be conducted to develop policies. 3. Studies on developing a hospice charge system and hospice standards that meet local conditions in Korea need to be conducted.

  • 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'.

  • The purpose of this study was to examine the level of human rights sensitivity and the types of perception in regards to the human rights of college students to enhance their human rights sensitivity. The study methodology included a t-test and variance analysis for the level of human rights sensitivity, and a Q-factor analysis for the perception types of human rights. As a result of examining whether there is a difference in human right sensitivity, it was found that female students were higher than male students, and juniors and seniors were higher than freshmen and sophomores. The human rights sensitivity of the students in the social and science department were the highest, and those who had volunteer experiences were more susceptible to human rights than those who did not. Students who registered for organ donation were higher than those who did not, and those who received human rights education showed higher human rights susceptibility than those who did not. Four perception types of human rights were analyzed 'universal social moralists', those who have an idealistic mindset and make decisions based on moral standards, 'practical realists', those who have no intention of breaking out of the social norm and who do not want to take any risks for human rights, 'social system advocates', those who have a clear understanding of the basic human rights concept, but don't think that they should break the rules of society for the sake of individual rights, and 'social contracts advocates', those who are willing to bend the rules of society for human rights, but not to the extent of ruining relationships. These study results are expected to contribute to the possibility of the social viewpoint that human rights sensitivity can be developed in the context of social experience as well as perception.

  • In modern society, private securities have developed their capabilities continuously. However, despite the fact that not only security industries have been considerably expanded in quantity, but also plenty of scholars published diverse papers relating to security problems, qualitative growths of private securities have not accomplished fully. Especially, securing the President would not be guaranteed only by PSS(Presidential Security Service). In order to secure the President successfully, it is necessary for all the social parts to strive to protect the President. In this respect, improving private securities, including academic fields, might be critical so as to succeed in securing the President. Without the supports from private securities, there might be lots of security problems in national context. Therefore, this study proposes several policy suggestions for the cooperation among PSS, private security industries and academic fields: (1) Providing a lot of practical knowledge from PSS to college students, (2) Personnel exchange between academic parts and PSS to promote the efficiency of securing the President, (3) Furnishing diverse information and knowledge about security to private securities, (4) Formulating security-searching standards, (5) Expanding educational institutions under PSS.

  • Purpose: The purpose of this study was to identify a model based on f the learning objectives in adult health nursing curriculums. The model can be eventually reflected in Korean National Nurse's Licensing Examination (KNNLE). Methods: The model was developed through a series of practical analysis by the task force team from June to October, 2011. The research team conducted the data synthesis and analysis from the learning objectives of adult health nursing drawn from selected national and international universities, from the adult health nursing areas in KNNLE, and from the current disease prevalence from clinical data in the representative university hospitals in Korea. Results: The current disease prevalence and mortality rates are on the increase especially for malignant neoplasm, heart diseases, suicide and diabetes. The items on the KNNLE of adult nursing are categorized by body systems into digestive system (15%), introduction (13.8%), respiratory system (11.3%), and cardiac system (11.3%). While the current system-based learning objectives covers extensive areas of adult health nursing, the core items are required to be selected based on core competences and core learning objectives to restructure the items of KNNLE. The first revised model is to consolidate and restructure the items microscopically in the subjects of adult health nursing by system. The second proposed model from macroscopic perspective is to build a comprehensive scheme of nursing curriculum by encompassing 8 subjects under current KNNLE and adjust the number of items accordingly. Conclusion: The items of KNNLE need to be gradually redesigned by considering the intervention need at clinical practice and the modified learning objectives of adult health nursing. Based on the job analysis on core competences for newly employed nurses performed by the Korean Accreditation Board of Nursing, it is necessary to establish the core learning objectives of adult health nursing and set up standards for core items in KNNLE.
