In this paper, an algorithm for a real-time automatic fingerprint identification system is proposed. The fingerprint feature volume is extracted by considering distinct and local characteristics(such as intensity and image quality difference etc.) in fingerprint images, which makes the algorithm properly adaptive to various image acquisitionj methods. Also the matching technique is designed to be invariant on rotation, scaling and translation (RST) changes while being capable of real-time processing. And the classification of fingerprints is performed based on the ridge flow and the relations among singular points such as cores and deltas. The developed fingerprint identification algorithm has been applied to various sets of fingerprint images such as one from NIST(National Institute of Standards and Technology, USA), a pressed fingerprint database constructed according to Korean population distributions in sex, ages and jobs, and a set of rolled-than-scanned fingerprint images. The overall performance of the algorithm has been analyzed and evaluated to the false rejection ratio of 0.07% while holding the false acceptance ratio of 0%.

The purpose and need of the study is to quantify the advantage or disadvantage of the environmental friendliness of the partitioning of nuclear fuel cycle. To this end, a preliminary study on the quantitative effect of the partition on the permanent disposal of spent PWR and CANDU fuel (HLW) was carried out. Before any analysis, the so-called reference radionuclide release scenario from a potential repository embedded into a crystalline rock was developed. Firstly, the feature, event and processes (FEPs) which lead to the release of nuclides from waste disposed of in a repository and the transport to and through the biosphere were identified. Based on the selected FEPs, the ‘Well Scenario’which might be the worst case scenario was set up. For the given scenario, annual individual doses to a local resident exposed to radioactive hazard were estimated and compared to that from direct disposal. Even though partitioning and transmutation could be an ideal solution to reduce the inventory which eventually decreases the release time as well as the peaks in the annual dose and also minimize the repository area through the proper handling of nuclides, it should overcome major disadvantages such as echnical issues on the partitioning and transmutation system, cost, and public acceptance, and environment friendly issues. In this regard, some relevant issues are also discussed to show the direction for further studies.

This study was performed through one-to-one interviews or group sessions with single un-married foreigners living and working in Korea. A total of 150 questionnaires were distributed, and 109 were analyzed. This demographic becomes immersed in local cuisine searching for new food dishes and experiences. These foreigners were an excellent test group who came from a non-Korean domestic cuisine background and who were subsequently exposed to Korean cuisine over an extended period during which changes occurred in their diets and food preferences. We found that the longer the foreigners stayed in Korea, the more they ate Korean food and adapted to traditional dishes such as Korean stews and hot-pots. In general, Chinese, Japanese, and South-east Asians regarded Korean food as nutritious, whereas people from a western or European background considered it health conscious food. In contrast, South-east Asians, in particular, found Korean food aroma unpleasant. This study describes how diets and views of Korean food evolved in foreigners with time by providing objective opinions and data on the acceptance of Korean food by foreigners and hints the direction in which Korean cuisine should be developed to further its globalization.

Korea government aims to generate 20 percent of its electricity with clean, renewable energy by 2030, while reducing its reliance on fossil fuel and nuclear power plants. Technically, solar energy has resource potential that far exceeds the entire global energy demand. Solar energy industry has experienced phenomenal growth in recent years due to both technological improvements resulting in cost reductions and government policies for renewable energy development and utilization. Even though solar power generation has several advantages over other forms of electricity generation, the major problem is the requirement of land which is scarcely available in the local site and its cost. This study analyzes the available capacity of landing and floating solar plants for the case of chonnam province in korea. The results of design capacity show about 7.5GW for landing and 1.5GW for floating solar power plant. Also, with a purpose to comprehend intention-behaviour gap about acceptance of solar community, the solutions are suggested.

This study examined the drivers' acceptance level of various active safety features with Korean drivers on Seoul urban and city roads. The test vehicle, 2013 Cadillac ATS, was equipped with FCA(Forward Collision Alert), LDW(Lane Departure Warning), SBZA(Side Blind Zone Alert), FRPA(Front/Rear Park Assist), RCTA(Rear Cross Traffic Alert), ACC(Adaptive Cruise Control), and AEB(Autonomous Emergency Braking). Participants had chances to run the tests on those systems in the parking lot accompanied by the 106km long stretch of predetermined route including local road and interurban highway in Seoul and Gyeonggi-do under normal traffic flowing environment. After the test, participants completed a series of questionnaires about the features they experienced. The results revealed that RCTA and SBZA systems received more favourable ratings compared to the other features in avoiding crashes. The respondents preferred sound alerts to haptic ones even though haptic warning methods were better in providing directional information.

The natural convection model of the consolidated system has been developed to make sure the removal of decay heat generated in the spent fuel for the loss of forced cooling accident. The numerical technique employed was based on the ADI scheme. The calculation of heat generation rate in the spent fuel was peformed by the ANS-79 decay heat model, and the nonuniform surface heat flux is assumed with a chopped sine curve for the conservative decay heat generation input. The sensitivity study was performed to examine the possibility of the pool bulk boiling by varying the various parameters, i.e. inter-fuel spacing ratio, heat generation power, and radius of the fuel rod. The application results of this model show that the natural circulation flow through compacted spent fuel bundles enables the pool temperature to control in a safe and effective manner, after the required cooling time. The corresponding acceptance criteria of the cooling time for rearranging the spent fuel rods were also found.

The objective of the present study was to investigate differences in quality of kimchi products produced in Korea, Japan, and China. Kimchi products from kimchi-producing countries with high consumer consumption such as Japan and China along with local products from Korea, where exporting has not yet started, were collected. Product pH, acidity, salinity, package pressure, gas production were assessed, and microbiological analyses and sensory evaluations were performed on kimchi products that were stored at either $4^{\circ}C$ for 63 d or $15^{\circ}C$ for 20 d. The pH and acidity results showed that as Japanese and Chinese kimchi had higher pH and lower acidity than that of Korean kimchi, which was determined to be indicative of insufficient microbial fermentation following kimchi production. Japanese kimchi had different microbial properties than those of Korean kimchi, which is due to differences in their manufacturing processes. Overall preferences derived from sensory evaluations were: Korean kimchi>Chinese kimchi>Japanese kimchi. The results of this study demonstrate the sensory superiority of Korean kimchi and may be useful when predicting consumers' acceptance level of Korean kimchi exported to other countries.

This study was performed by the literature review on housing of the aged in Korea with social constructionism perspective. This kind of research may be utilized as a theoretical framework for performance of any systems of housing for the aged. In terms of structural context, the value of conventional custom of filial piety thoughts and duty for family are being collapsed, which nay be suitable to the change of society, should be considered for positive acceptance of changes in ideology. In terms of institutional context, a method to grope for housing for the aged should be established through amicable cooperation between organizations of legalization concerned. In terms of organizational context, there is no organization that exclusively concern housing for the aged until now, thus, development of concrete manual is required for jobs of service in current department of policy for the aged. In terms of operational context, the service may include the understanding of characteristics of the aged and design of housing may also change the service of administration, and as cooperation in the local community care systems may change the service to the aged in the field. Connection of these services and operation of these organizations nay be required in the field to manage housing. Finally in terms of intersubjective context, as the form and method of housing management service is important, with understanding of the social meaning and importance on the role of manager.

Objectives: The purpose is to prepare measures to effectively improve college life adaptation by identifying relevance between interpersonal relation disposition and college life adaptation, college life stress and college life adaptation for dental hygiene students. Methods: 375 dental hygiene students attending some local universities in Gyeonggi-do were sampled for convenience. The results of this study are as follows. Results: First, As a result of interpersonal relation disposition according to general characteristics, superiority-dominance tendencies were higher in first and third graders, in groups with grades above 4.0 and groups with lower subjective economic levels. And the stress of college life was high for second graders and students with lower grades than 2.0. Second, According to the correlation between factors, governance-dominance, independence-responsibility, sympathy-acceptance, sociable-friendliness, and ostentation-intoxication of interpersonal tendency factors had proportional relationship with college life adaptation, rebellion-distrust and college life stress had inverse relationship. Third, The results of multiple regression analyses to identify factors that affect college students' adaptation to college life were in the order of stress in college life, first grade, sociable-friendliness, second grade, rebellion-distrust. Conclusion: In order to improve college life adaptation, counseling and practical mediation programs should be developed and applied to effectively manage and control the negativity and positivity implied by interpersonal relationships and college life stress.
