This study aims to examine both the theoretical framework and practical method for the building a subject-oriented collection of information resources form Internet. Through the study, a few conclusions as well as a suggestion were derived. 1. Conclusions : (1) The continuous learning and studying by the librarians working in the information society is required in order that they could have a broader recognition of the existence of various resources from Internet by subject, and that they could be armed with a greater ability to evaluate for the information filtering. (2) The use of a subject directory to collect needed information resources form Internet revealed the necessity for going through many steps linked by hierarchical indexes till arriving at the desired information, and accordingly the great time was needed to conduct the work. (3) In case of using various search engines, since the output of the relevant information largely depends on the adequate defining of the topic, the right selection of search terms and the accurate methods of inputting the keywords, systematic organization of the resources is not simple and easy. The classifying work of collected resources for the topic into the broader categories differs from that of the resources form other topics, for example, psychology, because of the idiosyncrasy of the contents of the each topic. (4) As one method to provide more revolutionary value-added service using Internet, it is necessary for the librarians to learn the skills to build the Web resource pages of subject-oriented collection of information resources from Internet on the specific subject. 2. A suggestion : Since the study did not complete the collection and organization of the information resources from the Internet on this topic, the remaining research and task should be the thorough collection of resources and the building the Web resource pages consisting of interconnecting links of indexes by spending greater time.

Producer and distributor of electrical and electronic equipment may directly collect waste electrical and electronic equipment that falls under the class to which the equipment they distributed belongs, or may join KERC(Korea Electronic Recycling Cooperative) and have KERC fulfill the duty to collect on behalf. In this study, the system of calculating the financial contributions is reviewed, and then the defined problems and improvement plan are proposed. First, the standard operation and time should be set for collection and transportation costs, taking into account the operation by collection type. Second, since there is a difference in the screening method of the recycling center, the standard cost for the allocation factor should be set by reflecting the difference in these methods and the characteristics of the product line being processed. Third, it is necessary to secure a budget of sufficient size by determining the median or average value rather than the minimum value in the forecast model for visit collection. This study is suggesting in that it examines the problems of the allotted contributions paid by the mutual aid members to KERC and suggests ways to improve them.

Purpose: The Cow's Milk-related Symptom Score (CoMiSS^TM) was developed as an awareness tool for evaluating cow's milk-related symptoms in otherwise healthy children. Using a convenience sample of participants, this cross-sectional study aimed to determine CoMiSS^TM values of symptomatic infants based on retrospectively or prospectively obtained information. Methods: CoMiSS^TM values were determined in infants aged <12 months with symptoms suggestive of cow's milk protein allergy or functional gastrointestinal disorders. The exclusion criteria were previous diagnosis with acute or chronic disease, treatment with a therapeutic formula, and in case of breastfeeding, an elimination diet followed by the mother. Two CoMiSS^TM values were assessed. A retrospective collection was defined as the collection of data after initial contact with the medical center but before the first medical consultation. A prospective collection was defined as the collection of data within 24 hours from the time of medical consultation but before starting any therapeutic intervention. The CoMiSS^TM total and individual component scores obtained retrospectively or prospectively were compared between groups using the Wilcoxon signed-rank test. Results: This study was performed between August and November 2019. Data of 110 children (62 males and 48 females), with a mean±standard deviation age of 18.2±11.7 weeks, were obtained. The total CoMiSS^TM value (p<0.001) and some individual component scores (crying, regurgitation, and stool) were significantly lower when collected prospectively than when collected retrospectively. Conclusion: CoMiSS^TM values were retrospectively and prospectively determined. Lower CoMiSS^TM values were obtained during prospective evaluation. Possible differences should be considered when using CoMiSS^TM in clinical practice.

The existing indoor localization method using Wi-Fi fingerprinting has a high collection cost and relatively low accuracy, thus requiring integrated correction of convergence with other technologies. This paper proposes a new method that significantly reduces collection costs compared to existing methods using Wi-Fi fingerprinting. Furthermore, it does not require labeling of data at collection and can estimate pedestrian travel paths even in large indoor spaces. The proposed pedestrian movement path estimation process is as follows. Data collection is accomplished by setting up a feature area near an indoor space intersection, moving through the set feature areas, and then collecting data without labels. The collected data are processed using Kernel Linear Discriminant Analysis (KLDA) and the valley point of the Euclidean distance value between two data is obtained within the feature space of the data. We build learning data by labeling data corresponding to valley points and some nearby data by feature area numbers, and labeling data between valley points and other valley points as path data between each corresponding feature area. Finally, for testing, data are collected randomly through indoor space, KLDA is applied as previous data to build test data, the K-Nearest Neighbor (K-NN) algorithm is applied, and the path of movement of test data is estimated by applying a correction algorithm to estimate only routes that can be reached from the most recently estimated location. The estimation results verified the accuracy by comparing the true paths in indoor space with those estimated by the proposed method and achieved approximately 90.8% and 81.4% accuracy in two experimental spaces, respectively.

Purpose: This study investigated Korean healthcare providers' attitudes toward sexual and gender minority (SGM) persons and their knowledge and behavior concerning the collection of data on sexual orientation and gender identity (SO/GI). Methods: In this cross-sectional, descriptive study, 137 Korean healthcare providers were recruited through convenience sampling from internet communities for medical professionals. A structured questionnaire was created using Google Surveys. The Mann-Whitney U-test, Kruskal-Wallis test, and Spearman correlation analysis were performed. Results: The sample was mostly women (80.3%) and nurses (83.9%), who had overall negative attitudes toward SGM persons and low levels of knowledge and behavior with regard to the collection of patients' SO/GI data. Participants in their 20s, who were religious, and had clinical experiences in treating or providing nursing care for SGM persons had higher levels of knowledge about the collection of SO/GI data. The level of engagement in collecting SO/GI data was higher among women and in their 20s and 30s, unreligious participants, nurses, and those with less than 10 years of clinical experience. Positive attitudes toward SGM persons were associated with higher levels of knowledge, but lower levels of behavior, regarding the collection of SO/GI data. Conclusion: It is important to recognize the diversity of patients' SO/GI and to collect the corresponding information. To this end, it is necessary to develop and use a standardized SO/GI form. Healthcare providers should also receive education and training related to the health of SGM persons to resolve health problems that disproportionately affect SGM persons and related health disparities.

Recent advances in sensor and mobile technologies have made it possible to collect user location data. This location information is used as a valuable asset in various industries, resulting in increased demand for location data collection and sharing. However, because location data contains sensitive user information, indiscriminate collection can lead to privacy issues. Recently, geo-indistinguishability (Geo-I), a method of differential privacy, has been widely used to protect the privacy of location data. While Geo-I is powerful in effectively protecting users' locations, it poses a problem because the utility of the collected location data decreases due to data perturbation. Therefore, this paper proposes a method using Geo-I technology to effectively collect user location data while maintaining its data utility. The proposed method utilizes the prior distribution of users to improve the overall data utility, while protecting accurate location information. Experimental results using real data show that the proposed method significantly improves the usefulness of the collected data compared to existing methods.

Household work is a productive activity, but it was not included in the System of National Accounts(SNA). Feminists and household economists complained this drawbacks of the SNA frequently. Finally, a Satellite Account for household production was allowed in the 1993 SNA. Korean government aimed to develop a Satellite Account for Korean household production. However, the development process u3s not efficiently peformed because of the lack of interests, relevant research, and appropriate dat3 at the national level in Korea. Therefore, this study aimed at examining to develop the Satellite Account for Korean household production in terms of its concept, method, data collection, and research topics. Several issues were discussed including methodology to value household production economically, appropriate ways for data collection, and future research directions in the topics of a Satellite Account.
