This research prepared safety standard for out-door fitness and this research's purpose is to evaluate and investigate safety condition for out-door fitness which was distributed in domestic residence by applying TUV standard which evaluate product's safety inspection. We choose twelve companies which have many sales' amount and investigated for ten out-door fitness which have high consumer preferences. As a result of that, the ratio of successful applicants for safety evaluation was 55.1%. The terms desired was evaluated highly in safety for out-door fitness's fixing condition. However, the terms desired was evaluated lowly in safety for movable condition. Fitness equipment which has high consumer preferences was compared lowly than other equipment in safety part. It was analyzed that there was no difference in safety evaluation according to manufacturing company. So, it is necessary to prepare safety standard by establishing law in order to prevent accident while they are using because we cannot think that fitness equipments which was distributed in domestic area have high safety. We think that preparing safety standard can influence on preventing accident and reinforcing out-door fitness manufacturing companies' competitive.

This paper aims to provide strategies to attract container cargoes for the Incheon port by analysing O/D of the container cargoes with the year-2004 export and import data from. The Korean customs service. O/D analysis was carried out with establishing optimal zones, which are defined as City, Gun, Gu(Korean administrative districts) to which the export-import service can be provided from a certain port with minimized freight(or transport) cost and stevedoring fee. For the Incheon port, 35 administrative districts including Seoul and Incheon in Kyunggi-Do and Kangwon-Do are recognized as the optimal zones, and approximately 25.50% of around 2.02-million-TEU per year of the cargoes from the zones are exported and imported through the port. The strategies to attract container cargoes was suggested by comparing the Incheon port to supposed-competitive ports. The Busan port(64.89%), Guangyang port(4.46%) and Pyeongtaeck port(3.35%) are supposed as the competitive ports which have a large proportion of handling the cargoes from the optimal zones. When comparing the Incheon port to these ports. The Incheon port requires a distinctive cost strategy, providing incentives to attract shipping companies and cargoes, improving efficiency related to loading-unloading at the port, and reinforcing Feeder-Network and advertisements about cost-saving to the shippers(the owners of goods) in the national capital region Consequently, the mentioned requirements are suggested as the strategies to attract cargoes for the Incheon port.

"Sanghanjeonsaengjip(傷寒全生集)" is a classic medical work, written by the outstanding physician Dohwa(陶華) in the Ming Dynasty. The characteristic of "SangHanJeonSaengJip" is that this book succeeded to the spirit of pattern identification and treatment of Treatise on Cold Damage Diseases, newly changed a table of contents by symptoms, and together with this indicated the prescriptions in accordance with diswase-pattern at "YujeunghwalInseo(類證活人書)", "Hwajegookbang(和劑局方)" etc. Also because this kept the existing ephedra decoction, cinnamom twig decoction, minor decoction of bupleurum, decoction for reinforcing middle-energizer and replenishing qi etc.'s name on and unlikely indicated the medicine composition, it caused confusion, but at the later ages "Euhakipmun(醫學入門)" the so-called 'Doci(陶氏)' was added to the prescription name, so we are able to distinguish. Together with this, this book dose not indicate the dosage of medicine and indicates the first, the second, and the third classes[上中下] below medicine. As this dose not mean the three grades of quality"good, fair, and poor[上中下] of "Shennong's Classic of Materia Medica" but expresses the sovereign medicinal as the first class[上], minister medicinal as the second class[中] and assistant and courier medicinal as the third class[下], doctors can voluntarily decide the dosage of medicine in accordance with the degree of disease. At this thesis, I single out ten chapters in contents of 2nd volume named Hyeong(亨) corresponding to the details, among "Sanghanjeonsaengjip(傷寒全生集)". I discussed superficial fever types of exogenous febrile disease in chapter 1, aversion to cold types of exogenous febrile disease in chapter 2, syndrome caused un-sufficient sweating in chapter 3, organic fever types of exogenous febrile disease in chapter 4, aversion to wind types of exogenous febrile disease in chapter 5, Tidal fever types of exogenous febrile disease in chapter 6, Alternative attacts of chills and fever in chapter 7, Dysphoria with smothery sensation in chapter 8, Fidgetiness of exogenous febrile disease in chapter 9, and Headache of exogenous febrile disease in chapter 10, and together with this I discussed, in detail, which influence the prescriptions which are listed on each chapter have caused on future generations In accordance with this, I think that the above-mentioned symptoms and prescriptions are important when I research cold damage and warm disease study. So I orderly research revision, annotation, rendering and an investigation.

The improvements of berth productivity is closely related to berth/port systems and its relationship extends to the overall pattern of port development/logistics, transport and trade. Since ports in general and berths in specific function as a bridge transferring seaborne cargoes from seaside to landside and vice versa, berth productivity improvements should be considered in terms of the total system in which the cargoes are transported from origin to destination via berths/ports. In that respect, the objective of this study is to improve berth productivity which is a vital factor in the strategic planning in port development and operation and logistics. According to a literature survey on the subject, the contents of the studies have been limited to either a macro-perspective or a micro-perspective which is only a partial solution to the problem. Hence, this limitation requires an integrated approach to find and ultimate solution, which should be considered not separately, but as a whole. The contents and scope of this study cover the improvements of berth productivity in conjunction with strategic planning in port development. efficient operation and logistics from two different viewpoints, macro- and micro-perspective. After that, a combination of these two perspectives is applied to the integrated approach due to lacking a comprehensive perspective from either macro-approach or micro-approach. In reality, a port itself is a complex and dynamic organization. Therefore, a comprehensive insight needs an integrated approach for the long-term national economic development. In this approach, the utmost importance is how to find the bottlenecks and to solve the problems effectively from the beginning stage in port development. In conclusion, derived from the macro- and micro-perspective. the attempt to establish an integrated approach is the merit of this study, which is required as a comprehensive measure since none of the two can be a solution independently. In terms of reinforcing this study, it needs further empirical research due to the restriction of the theoretical method of this paper. Consequently, the reinforced research will be able to enhance the integrated approach on the basis of the conceptual perspective.

This study analyzed the direct and indirect effects of job competency education on job goal setting, job preparation behavior and first job satisfaction from the perspective that successful employment requires improving the job ability needed for college students. Data on 5,044 students were analyzed based on the 2013GOMS of Graduates Occupational Mobility Survey(GOMS). The study findings are summarized as follows. First, job competency education not only acted positively on job goal setting but also contributed to promoting job preparation behavior. Second, job preparation behavior contributed to improving satisfaction with the first job. Third, indirect effects of job competency education and job goal setting in first job satisfaction. In conclusion, job competencies enhances the possibility that college students may obtain their wanted job by setting a clear goal for their job and having a positive effect on the required behavior. Accordingly, college student should try to reinforce their special capability to accomplish the given job as career professionals in consideration of their aptitude rather than devoting themselves to reinforcing their basic capability such as linguistic ability. For this purpose, both universities and the government should develop educational programs for college students to grasp their aptitude and cultivate their special ability to become career professionals and provide a foundation for them to become talented professionals armed with special capability by proving support for job ability improvement.

This study was designed to identify the knowledge, perception, self-efficacy, and performance on radiation protection among perioperative workers in terms of radiation protection. The factors affecting the performance of radiation protection were identified, and provide basic data for the development of an effective radiation protection education program. The sample was comprised of 166 perioperative workers who agreed to participate in this descriptive study. Data analysis was performed using the t-test, analysis of variance, Pearson's correlation, and multiple regression analyses on the SPSS 23.0 Program. The average time of radiation exposure was 3-4hoursThe radiation protection education experience was 11.4%. The average score of radiation protection knowledge was $8.61{\pm}2.51$; the perception was $4.59{\pm}0.64$; and the performance was $2.99{\pm}0.90$ There was a significant difference in the degree of radiation defense knowledge and performance among the general characteristics (p <001). Knowledge of radiation protection was correlated with the perception. The performance of radiation protection was correlated with the knowledge. The knowledge and perception of radiation protection behaviors should be increased to improve radiation protection performance. Therefore, it is important to promote the performance of radiation protection behaviors by improving the perioperative workers' knowledge of radiation protection through reinforcing radiation-related education.

The objective of this study is to catch hold of the problem occurring in the process in which librarians have obtained government publications and to show the method that can construct the rational distribution system of government publications. For this study, total 56 librarians who work for 44 institutes sponsored by central government and 12 institutes sponsored by local government were chosen as the objects of research and questionnaire survey to know how to obtain government publications. How to construct the rational distribution system of government publications is as follows. (1) The exclusive organization to manage overall service for government publications should be established newly or previous similar organization should be reorganized. (2) As reinforcing the law concerning deposit copy, government publications should be distributed obligatorily to all of the depository agency, and the depository library system of government publications should be introduced and managed newly. Especially the management of deposit copy and the depository library system of government publications should be undertaken by the exclusive agency of government publications. (3) Free-government publications should be converted to pay-government publications as much as possible so that everyone can purchase government publications easily. And free-government publications which are difficult to convert to pay-government publications should be distributed according to rational standard by the exclusive agency of government publications. (4) Pay-government publications should be sold by private distribution organization under exclusive agency of government publications. Also printing, editing and pricing of pay-government publications should be done by private distribution organization to compete with general books. (5) In order to promote the sales of pay-government publications, the sales centers of government publications must be established even in city and county. Also special government publications which have much demand should be sold even in general book stores. Especially the management of the sales centers should be undertaken by private distribution organization. (6) It is necessary to abolish or improve unreasonable regulations or system related to government publications and to make legislative, institutional devices for government publications. (7) The public relations for government publications should be enforced much through TV or radio etc. , and the various bibliographic tools of government publications should be developed and disseminated for the sake of much utilization of government publications. (8) By using new technology like CD-ROMs or communication networks, electronic production and distribution of government publications should be push ahead positively. And electronic information distribution center to su n.0, pport it should be established by government agency.

The thermomechanical properties and morphologies of nanocomposite fibers of poly(ethylene terephthalate)(PET) incorporating thermally stable organoclays are compared. Dodecyltriphenyl-phosphonium-mica($C_{12}PPh-Mica$) and 1-hexadecane benzimidazole-mica ($C_{16}BIMD-Mica$) were used as reinforcing fillers in the fabrication of PET hybrid fibers. Dispersions of organoclays with PET were studied by using the in-situ polymerization method at various organoclay contents to produce nano-scale composites. The thermo-mechanical properties and morphologies of the PET hybrid fibers were determined using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), wide angle X-ray diffraction (XRD), electron microscopy (SEM and TEM), and a universal tensile machine (UTM). Transmission electron microscopy (TEM) micrographs show that some of the clay layers are dispersed homogeneously within the polymer matrix on the nano-scale, although some clay particles are agglomerated. We also found that the addition of only a small amount of organoclay is enough to improve the thermal stabilities and mechanical properties of the PET nanocomposite fibers. Even polymers with low organoclay content (<5 wt%) were found to exhibit much higher thermo-mechanical values than pure PET fibers.

The lignin-based carbon nanofiber reinforced epoxy composite has been prepared by immersing carbon nanofiber mat in epoxy resin solution in order to evaluate the physical and mechanical properties. The thermal and mechanical properties of the carbon nanofiber reinforced epoxy composite were analyzed using thermogravimetric analysis (TGA), differential scanning calorimeter (DSC) and tensile tester. It was found that the thermal properties of the carbon nanofiber reinforced epoxy composite improved, with its glass-transition temperature ($T_g$) increased from $90.7^{\circ}C$ ($T_g$ of epoxy resin itself) to $106.9^{\circ}C$. The tensile strengths of carbon nanofiber mats made from both lignin-g-PAN copolymer and PAN were 7.2 MPa and 9.4 MPa, respectively. The resulting tensile strength of lignin-based carbon nanofiber reinforced epoxy composite became 43.0 MPa, the six times higher than that of lignin-based carbon nanofiber mats. The carbon nanofibers were pulled out after the tensile test of the carbon nanofiber reinforced epoxy composite due to high tensile strength (478.8 MPa) of an individual carbon nanofiber itself as well as low interfacial adhesion between fibers and matrices, confirmed by the SEM analysis.

As large-scale housing sites are being developed rapidly in Sejong City, which was launched in 2012 for resolving the adverse effects of overconcentration in the capital area, promoting balanced development of the country, and reinforcing national competitiveness, changes in spatial structure are expected in the surrounding areas. For setting the directions of urban planning, it is essential to understand changes in spatial structure. This study purposed to measure changes in the spatial structure of neighboring areas resulting from the construction of Sejong City by approaching from the aspect of spatial interaction. In the analysis, we calculated population potential for future spatial interaction using the accessibility model, and interpreted quantitatively and qualitatively the outcomes of spatial interaction among neighboring areas before and after the construction of Sejong City using population potential as an indicator. According to the results of the analysis, the impact range of the population potential of the subject areas had been shrinking continuously since 1995, and in 2013 population potential dispersed as the population concentrated on and around Cheonan City. Although Sejong City, as a new area of population potential, was not found to play the role of a pivotal point for the surrounding areas, it is probably because the analysis was made just after people began to move to Sejong City. Accordingly, along with the effort of Sejong City to reach the planned population, it is necessary to keep monitoring changes in related factors and changes in the spatial structure of the surrounding cities resulting from the growth of population.
