현대사회는 삶의 양식 변화에 따라 복잡하고 다양한 분야로 생활 영역이 확대되고 있다. 사람들의 의식도 변화하면서 각종 사회문제가 수반되고 이에 대한 대책도 다방면에서 이루어지고 있다. 특히 학교폭력 문제가 관심 대상이 되면서 정부 관련 부처가 합동으로 신고센터를 마련하고 전문상담 요원들이 피해 신고를 접수하며 상담하고 있다. 상담 요원들은 업무 처리 과정에서 심신의 소진을 경험한다. 따라서 소진의 원인이 되는 요인이 무엇인지 연구하여 효과적인 상담 업무 수행에 기여할 필요성이 제기된다. 본 연구는 2019년 2월부터 2020년 5월까지 117 신고센터에서 근무하는 상담 요원 10명을 대상으로 업무 처리 과정에서 체험한 사실을 면담하고 수집하여 Colaizzi의 현상학적 연구방법으로 분석하였다. 연구의 결과에서 소진 요인은 첫째 '117 신고센터 경험'에서 기관 통합 시기의 상담요원 갈등, 둘째 '소진'에서 전문상담 요원은 정서적 고갈, 비인간화, 성취감 결여 증상 등의 경험이었다. 상담 요원들의 소진 요인을 예방하고 극복하기 위해 사기 증진방안 마련이 필요하였다. 이는 각종 익명의 상담 방식이 활용되는 산업화·정보화 시대에 특수 직종 상담 요원의 근무환경 개선에도 유용한 자료가 될 것으로 기대한다.

대부분의 재난 상황 관리 시스템의 목표는 재난안전대책본부 지휘자의 정확한 상황 판단을 목표로 하고 있다. 이를 위하여 센서, CCTV, 기상 등으로부터 정보를 실시간으로 수집하고, 현장 담당자로부터 현장 상황 정보를 받아서 판단하는 형태로 구성되어 있다. 그러나 이러한 모델은 현장 담당자의 세부 임무 관리 및 임무 수행 상황에 대한 관리가 부족하여 현장 대응력 부족으로 나타나고 있다. 그러므로 본 연구는 이러한 현장 임무 수행 능력의 관리와 상황 관리를 통합적으로 진행할 수 있는 모델 개발에 초점을 두었다.

As the number of legacy database systems and the size of data to manipulate have been vastly increased, it has become more difficult and complex to analyze characteristics of data. To improve the efficiency of data analysis and help administrators to make decisions in business life, BI(Business Intelligence) system is used. To construct data warehouse and cube from legacy database systems makes it easy and fast to transform raw data into integrated and categorized meaningful information. In this paper, we built a BI system for an University administration. Several source system databases were integrated to data warehouse to build data cubes. The implemented BI system shows much faster data analysis and reporting ability than the manipulation in legacy systems. It is especially efficient in multi dimensional data analysis, nonetheless in single dimensional analysis.

Objectives: The purpose of this paper is to help the development of qualitative research in the field of Korean medicine and policy support for postpartum depression. Methods: Qualitative studies related to postpartum depression retrieved from five databases were evaluated independently by two researchers using the integrated criterion, Consolidated criteria for reporting qualitative research (COREQ). In addition, each subject of study was qualitatively synthesized. Results: A total of 1,374 papers were searched and 13 papers were finally selected. The results of the study using COREQ lacked information about the researchers. The results of the study were integrated into three themes: "Feeling Failure", "Struggling for self-identity and role of mother" and "Seeing Help and Recovery". Conclusions: Postpartum depression can be accessed through various methods such as Korean medicine counseling, acupuncture and herbal medicine, and further research and manual preparation is required.

Purpose - The current study attempts to reveal the causal relationship and identify the interrelationships among individual value, product selection attribute, and re-purchase intention of consumers when purchasing kimchi. Research design, data, and methodology - The surveys were distributed and retrieved to kimchi consumers in Seoul and Gyeonggi Province who were over 20 years old and who had purchased kimchi before. The current study utilized the self-reporting survey as the research method. Result - First, as a result of hypothesis 1 test, both internal value and external value had a significant effect. Second, as a result of hypothesis 2 test, while internal value had a significant effect, external value did not have a significant effect. Third, as a result of hypothesis 3 test, while internal value had a significant effect, external value did not have a significant effect. Fourth, as a result of hypothesis 4 test, all quality, brand, and price had a significant effect. Fifth, as a result of hypothesis 5 test, while internal value had a significant effect, external value did not have a significant effect. Conclusion - The current study aims to establish marketing and service strategies to maximize profits and secure competitive advantage in the kimchi industry through changes in the management strategy of the Korean kimchi industry.

The handover procedure of IEEE 802.11 wireless local area networks (WLANs) introduces significant delay, which can degrade the quality of service (QoS) especially for delay-sensitive applications. Although studies have been conducted to support handover in SDN-based WLAN, there is no research to reduce the channel scanning procedure that takes up the most delay time in the handover process. The channel scanning procedure is essential to determine the appropriate access point (AP). To mitigate this problem, this paper proposes a SWITCH: SDN-WLAN integrated handover scheme for QoS-Guaranteed mobile service. In SWITCH, each AP periodically broadcasts beacon frames through different channels in a predetermined order that includes the operating channel information of the AP. This allows mobile stations (MSs) to receive the beacon frames of nearby APs, and therefore they can determine the appropriate APs for handover without the channel scanning procedure. By reporting the information of the newly moved AP to the SDN controller, a flow rule is installed in advance to provide fast handover, and packet loss is reduced by buffering data destined for MS. In addition, the proposed scheme can adaptively operate SWITCH to consider the user location and QoS requirement of flow to save radio resource overhead. Performance evaluation results demonstrate that SWITCH can reduce the handover delays, flow table utilization ratio and radio resource overhead while improving the network throughput.

This paper presents the design results of a Multi-band Global Positioning System (GPS)/Korean Positioning System (KPS) Real-Time Kinematics (RTK) precise positioning simulator and evaluate its functionalities. The designed simulator consists of a trajectory generation module, a Radio Frequency (RF) signal generation module, a RF signal reception module, a coarse positioning module, a precise positioning module, and an error statistics reporting module. Simulations in realistic scenarios confirm that the proposed baseband simulator works appropriately. The developed simulator can adjust the type, number, band, and Pseudo Random Noise (PRN) code type of the satellite constellation in various ways, and the practical positioning performance can be tested. It can also reflect the channel influence at the actual RF stage and the influence during the initial synchronization and tracking process. Considering such advantages, the proposed simulator would be useful in future researches and developments related to KPS.

The main purpose of this paper is to develop a Delphi Decision Support System based on the web, which can improve the conventional Delphi method. Among major drawbacks of the conventional Delphi methods are cost and efforts to distribute and collect the questionnaire by the regular mail and the tardiness in collecting, categorizing, analyzing, and reporting the result of the questionnaire. With the proposed Delphi Decision Support System, the moderator sends the e-mail to invite the member of panels so that they may visit the homepage of the Delphi Decision Support System. When the panelists input their opinions about the issues, the Delphi Decision Support System analyzes the inputs and reports the result without delay. To implement the Delphi Decision Support System, we integrated Microsoft SQL Server 6.5, jdbcKona/MS SQLServer 4 JDBC driver, and Java Development Kit 1.2

A PC window-based computer code, CONPAS(CONtainment Performance Analysis System), has been developed to integrate the numerical, graphical and results-operation aspects of Level 2 probabilistic safety assessments (PSA) for nuclear power plants automatically. As a main logic for accident progression analysis, it employs a concept of the small containment phenomenological event tree(CPET) helpful to trace out visually individual accident progressions and of the large supporting event tree(LSET) for its detailed quantification. Compared with other existing computer codes for Level 2 PSA, the CONPAS code provides several advanced features: computational aspects including systematic uncertainty analysis, importance analysis, and sensitivity analysis, reporting aspects including tabling and graphic, and user-friend interface.
