  • The purpose of this study was to suggest the justification for social recognition of childcare staff through a review of Axel Honneth's recognition theory of childcare staff's caring work, the Constitution, the Infant Care Act, and the National Human Rights Commission Act. As a result of the study, first, the poor working environment of childcare staff was confirmed. Despite the continuous intervention of childcare policies to improve the working environment of childcare teachers, poor working conditions such as annual/monthly vacation and rest time guarantee were confirmed. Second, the human rights violations of childcare staff were confirmed. The installation of CCTV installed to prevent child abuse in childcare institutions confirmed not only the human rights violations of childcare staff but also the psychological pressure of childcare staff who are monitored 24 hours a day. Third, this study has significance in that it suggests the justification for social recognition of childcare staff through revision and supplementation of the current law for appropriate performance evaluation of childcare.

  • This study was conducted to identify the food components and nutrition value of major fish roes on the market in Korea. The proximate compositions of the roes were 60.02-82.85% moisture, 14.61-29.21% protein, 1.24-14.59% lipid and 0.88-1.78% ash. The major total amino acids in the roes were glutamic acid, leucine, aspartic acid, lysine, and alanine. The major fatty acids were 22:6n-3 (docosahexenoic acid, 9.37-32.68%), 16:0 (5.96-21.39%), 18:1n-9 (12.64-25.30%), and 20:5n-3 (eicosapentaenoic acid, 3.79-16.99%). The mean major-mineral levels were phosphorus (291.63 mg/100 g edible portion), potassium (271.00 mg), sodium (175.86 mg), calcium (24.02 mg), and magnesium (22.15 mg). The mean trace-mineral levels were zinc (7.75 mg), iron (3.68 mg), and copper (0.81 mg). The results suggest that these fish roes are good sources of proteins, amino acids, n-3 fatty acids and minerals.

  • The proximate composition and mineral contents of 18 subtropical fish species caught off the coast of Jeju Island, Korea were determined. The mean moisture content was highest (78.0%) in the eight species of lean fish, lowest (72.6%) in the four species of medium-fat fish, and intermediate (75.4%) in the six species of low-fat fish. The lipid content was in the order of medium-fat fish > low-fat fish > lean fish. The protein content ranged from 17.7% to 18.9%. The mean macro-mineral contents in the 18 species were 290.2 mg/100 g edible portion K, 146.6 mg P, 113.5 mg Na, 67.2 mg Ca and 38.3 mg Mg. The mean value of micro-mineral contents were 2.1 mg Fe, 1.7 mg Cu and 1.5 mg Zn. These results suggest that subtropical fish from Jeju Island are good sources of protein, lipid and minerals.

  • In genaral appraisal is process of the determining the length of the time records should be retained, and is defined as selecting records with second value. However, appraisal in boroad term includes analysis which value records have as well as selecting archival records. It means that analysis of Records value is carried and reflected in every processes of maintenance, use and disposition of records. One of characteristic in records and archives management is that records process doesn't finish as one process, but it creates and manages records repeatedly. When another records are created again after the previous process in these system, it should creates records with better value than before. It pursues positive circle system which satisfy users whenever it starts. The study reviewed how analysis of records value is reflected in Records and archival system in Korea, and analysed Public Records and Archives Act to approve it. In results the study suggests having positive circle system finally.

  • In this paper, we tried to present the basic framework so that we can conduct more systematic research on natural healing through fusion research, which combines the service marketing of natural healing field with the service marketing. This study investigated the user's satisfaction and intention to reuse natural and aesthetic experiences. People aged 20 to 50 across the country were given a range commonly known as "naturopathy," and the survey was conducted on those who experienced it. Analysis of data was performed using the SPSS 21.0 and AMOS 21.0 programs. Studies have shown that naturopathy experiences have a positive effect on customer satisfaction. After verifying the effect of the quality of naturopathy experience on customer satisfaction and reuse, it was found that customer satisfaction greatly affected customer satisfaction and customer satisfaction had a very high impact on the intention of reuse.

  • The document-term frequency matrix is a general data of objects in text mining. In this study, we introduce a traditional term weighting scheme TF-IDF (term frequency-inverse document frequency) which is applied in the document-term frequency matrix and used for text classifications. In addition, we introduce and compare TF-IDF-ICSDF and TF-IGM schemes which are well known recently. This study also provides a method to extract keyword enhancing the quality of text classifications. Based on the keywords extracted, we applied support vector machine for the text classification. In this study, to compare the performance term weighting schemes, we used some performance metrics such as precision, recall, and F1-score. Therefore, we know that TF-IGM scheme provided high performance metrics and was optimal for text classification.

  • Many researches proposed federated query engines to perform query on several homogeneous or heterogeneous datasets simultaneously that significantly improve the quality of query results. The existing techniques allow querying only over a few heterogeneous datasets considering the static binding using the non-standard query. However, we observe that a simultaneous system considering the integration of heterogeneous metadata standards can offer better opportunity to generalize the query over any homogeneous and heterogeneous datasets. In this paper, we propose a transparent federated engine (DRAZ) to query over multiple data sources using SPARQL. In our system, we first develop the ontology for a non-RDF metadata standard based on the metadata kernel dictionary elements, which are standardized by the metadata provider. For a given SPARQL query, we translate any triple pattern into an API call to access the dataset of corresponding non-RDF metadata standard. We convert the results of every API call to N-triples and summarize the final results considering all triple patterns. We evaluated our proposed DRAZ using modified Fedbench benchmark queries over heterogeneous metadata standards, such as DCAT and DOI. We observed that DRAZ can achieve 70 to 100 percent correctness of the results despite the unavailability of the JOIN operations.
