Historical background of computer files is briefly outlined. Descriptive examples of phisical area of computer files revealed in existing cataloging rules and manuals are examined and analyzed in terms of consistency identification and term standardization. An analysis of examples may provide the basis for enhancing organizing computer file.

This study of 855 clinical nurses was conducted using a questionnaire that include tour different scales; the motives of determining their profession, the attitudes toward their profession, the general items, and desire and expectation to their profession and society. The data were analyzed by Chi-Square Test and Percentage. The results of this study included Hypothesis are as follows; The respondents were 855 (78.6%) among 1088 clinical nurses who were employed by General of Educational hospitals through the city of Seoul, Pusan, Taegu, Daejun, Kwangju, and Wonju. 1) a. In the Age Distribution, the majority of respondents were under the age of 30yrs(88.2%) and the minority were above 31yrs(11.2%), and the preponderance of the majority to minority(9:1) was noted. In compared with area, a group above 31yrs old in Seoul (6.9%) was lower than other area (16.3%). b. The types of Educational background were 16.3% in Voc.Tr. School, 66.5% in Diploma and 17.1% in Degree.146 clinical nurses were from the Degree course, and 142 (97.3%) CN among those of them were occupied around Seoul and 4(2.7%) around other area. c. In the Marital Status,71,5% were the unmarried and 28.5% were the married. And compared with the area was 20.4% in Seoul and 41.4% in other area. d. Most common Length of Clinical Experience after graduation was under tile 2yrs (55.4%), 3yrs(14.2%, and 4yrs (6.2%). In compared with area, Seoul (15.3%) was lower than other area (38.1%) above 5yrs of clinical experience, and the preponderance of tile other area to Seoul as 2.5: I was noted. 2) a. Hypothesis 1 was significant relation between the types of Educational Background of the CN and their motives for selection of Nursing, P-value was below 0.01. b. There was a significance on hypothesis 2 (P＜0.01): that was relation between their motives for selection of clinical nursing field after their graduation and the area which they were employed. c. Hypothesis 4 was accepted as significant relation between the level of satisfaction of their clinical experience after their graduation and the types of educational back ground, P-value was below 0.01. d. There was a significance on hypothesis 5(P＜0.01) that was relation between the CN's response about the orientation program and the area which they were employed. e. Hypothesis 6 was retained as significant relation between the area and inservice educational programme of their employed hospital was practising or not. P-value was 0.01. f. Hypothesis 7 was retained as significant relation between the area and the CN's response about the inservice educational programme of their employed. P-value was below 0.01. g. There was a significance on hypothesis 8 (P<0.0l) that was relation between the CN's experience on attending the professional meeting and the area. h. Hypothesis 10 was accepted as significant relation between the response about the present licence system and their educational background. p-value was below 0.01. i. There was a significance on hypothesis 11 (P fO.01) that was relation between the carrying out the regular and delivery vacation and the area. J. Hypothesis 12 was accepted as significant relation between the CN's consideration of the lack of leisure and their marital status. p-value was below 0.01' k. There was a significance on hypothesis 13 (P <0.01) that was relation between the CN's response about their salary and their marital status. l. Hypothesis 14 was significant relation between the most difficulties of CN during their working and the hospital which they were employed. p-value was below 0.01.

In this paper, we proposed a deep learning-based detection method using Saliency Attention to detect salient objects in images. The salient object detection separates the object where the human eye is focused from the background, and determines the highly relevant part of the image. It is usefully used in various fields such as object tracking, detection, and recognition. Existing deep learning-based methods are mostly Autoencoder structures, and many feature losses occur in encoders that compress and extract features and decoders that decompress and extend the extracted features. These losses cause the salient object area to be lost or detect the background as an object. In the proposed method, Saliency Attention is proposed to reduce the feature loss and suppress the background region in the Autoencoder structure. The influence of the feature values was determined using the ELU activation function, and Attention was performed on the feature values in the normalized negative and positive regions, respectively. Through this Attention method, the background area was suppressed and the projected object area was emphasized. Experimental results showed improved detection results compared to existing deep learning methods.

The groundwater quality in Boseong area was characterized and their background concentrations were estimated based on the chemical data obtained from 200 groundwater samples collected during July 2019. Groundwater data were classified into two groups: Group 1 with NO₃^- < 44.3 mg/L and Group 2 with NO₃^- ≥ 44.3 mg/L. Results of t-tests indicate that groundwaters in Group 2 are significantly higher in water temperature and Ca concentration and significantly lower in F, As, Pb and Zn concentrations. It was also revealed that groundwaters Group 2 are closely linked to low pH, alkalinity, NH₄, NO₂, F, As, Fe, Mn, Pb and Zn levels, and high EC and water temperature. Background concentrations were estimated using the the BRIDGE method. The results depicted the higher levels in NO₃, NH₄, PO₄, As, Fe, Mn than the ones estimated by MOE and KECO (2018; 2019), which were prepared for the three catchment units in Boseong. The results of this study are believed to have more reliability because more data were used.

This paper describes a new face detection method that is a pre-processing algorithm for on-line face recognition. To complement the weakness of using only edge or rotor features from previous face detection method, we propose the two types of face detection method. The one is a combined method with edge and color features and the other is a center area color sampling method. To prevent connecting the people's face area and the background area, which have same colors, we propose a new adaptive edge detection algorithm firstly. The adaptive edge detection algorithm is robust to illumination variance so that it extracts lots of edges and breakouts edges steadily in border between background and face areas. Because of strong edge detection, face area appears one or multi regions. We can merge these isolated regions using color information and get the final face area as a MBR (Minimum Bounding Rectangle) form. If the size of final face area is under or upper threshold, color sampling method in center area from input image is used to detect new face area. To evaluate the proposed method, we have experimented with 2,100 face images. A high face detection rate of 96.3% has been obtained.

Most of precedent studies related to hip hop culture and fashion, which have been conducted till now were progressed under only theoretical background of hiphop, not the changed status of hiphop currently. Practical studies explaining the status of hip hop in popular culture, especially, the area of popular fashion are insufficient. Therefore, this study was conducted by focusing on cultural characteristics and musical characteristics by the stream of period, for which concept hip hop is accepted to people currently and which effect it makes on the area of fashion. Especially, the study was progressed by dividing periodical background into before and after the 2000s because there was the most noticeable change for the genre of hip hop in that period. Because of the appearance of 'Alternative hip hop' which is a sub-genre of hip hop music, hip hop music was changed to be more popular. Also, hip hop fashion also showed big changes. Hip hop fashion before 2000s had showed poor conditions, resistance, complex and alienation of them by their fashion. On the other hand, hip hop fashion after 2000s also showed popular characteristics because of high-level environment and social status. This study intended to understand and grasp hip hop as a kind of cultural situation coexisted by many-sided characteristics as well as redefine the changed concept and contents of new hip hop currently.
