This research suggests the strategic adoption methodology of Customer Relationship Management. The backgrounds of CRM is the business environment changing that Market power is shifting to the customer who has unprecedented powers of choice today. The strategic adoption of Customer Relationship Management determines the value, needs and preferences of each customer or customer segment. Customer Relationship Strategy is an explicitly defined plan for how a company has decided to connect with, relate to, and focus on its chosen customers to create value. Deliberate decisions must be made, often involving trade-offs, so that investments are aligned with customer needs and value. Plan defined in terms of target customers value proposition, role in value delivery, and risk/reward sharing. All customers are not created equal; specific customers and/or customers segments are more desirable/valuable to pursue. Key premise of CRM is that value can be created by changing company's business model to better connect with customers. Area of service of Customer Relationship Management are as follows. Portfolio strategy, Market Opportunity Assessment, Brand Equity, Market Positioning, Pricing, Channel Strategy, Market Segmentation. Target Market Identification, Customer LifeTime Value Analysis, Customer Profitability, Customer Connections Economics Analysis. The objects of CRM are maximizing customer service effectiveness, improving customer loyalty, increasing customer service efficiency, optimizing intelligence about customer behaviors and preferences.

Objectives: The purpose of this review is to evaluate the efficacy of moxibustion for stress urinary incontinence (SUI) in women. Methods: For relevant randomized controlled trials (RCTs), we searched the following databases from their inception to September 1, 2020: The Cochrane Library, PubMed, EMBASE, Chinese National Knowledge Infrastructure Database (CNKI), Koreanstudies Information Service System (KISS), Research Information Sharing Service (RISS), and National Digital Science Library (NDSL). The key search terms were 'stress urinary incontinence' and 'moxibustion'. Data extraction and assessment of risk of bias were conducted by two authors independently. Results: A total of 11 RCTs were finally included in this systematic review. In all studies, moxibustion treatment was applied as an adjuvant therapy to the conventional treatment, and the most common conventional treatment was pelvic floor muscle training (PFMT). The treatment group (conventional treatment plus moxibustion) showed statistically more significant effect than the control group (conventional treatment only) in various evaluation indicators including urinary incontinence frequency, 1 hour urine pad test, quality of life, the clinical efficacy rate, and pelvic muscle strength. Conclusions: In this study, we investigated the efficacy of moxibustion as an adjuvant therapy for female SUI patients. Further studies are needed to supplement the safety of moxibustion and the evaluation of moxibustion dose.

Increasing productivity of knowledge workers is a significant issue in the 21st century referred as knowledge-based society. The core key word is behavior of knowledge transfer among members of an organization. The objective of this study is to investigate a model based on Triandis theory and Social Capital theory. This explored the antecedent factors of knowledge Transfer in ITO(Information Technology Outsourcing) Organization. Data were derived from 42 respondents working IT Cooperation in Seoul, Korea. In this paper, we introduce the research model for the knowledge transfer. In order to validate the proposed research model, social network analysis tool, UCINET, a structural equation modeling tool, SmartPLS, was utilized. The empirical result showed that, all antecedent factors (intention of knowledge sharing, anticipated reciprocal relationships, subjective norm, closeness network centrality) of knowledge transfer behavior were significant. In conclusion, findings and implications were discussed and limitations of the study and future research directions were suggested.

클라우드 컴퓨팅, 스마트워크 등으로 IT 환경 변화가 진행됨에 따라 기존의 경계 보안 모델이 한계를 보이고 있으며, 소프트웨어 정의 경계(Software Defined Perimeter)가 그 대안으로 논의되고 있다. 하지만, SDP Spec 1.0에서는 장치등록 절차와 정책 배포 과정 및 인증 키의 생성과 공유 과정이 명시되어 있지 않다. 이에 본 논문에서는 단일패킷인증(Single Packet Authentication)의 동작 절차를 개선하여 기존의 SDP 접근통제의 문제점을 보완하는 방법을 제안한다. 개선된 제안 방법을 통하여 기존 접근통제 방법에 비하여 일관되고 자동화된 통합 접근 통제 정책을 구현할 수 있음을 보이고자 한다.

This paper proposes an advanced circuit for the capacitive type fingerprint sensor signal processing and an effective isolation structure for minimizing an electrostatic discharge(ESD) influence and for removing a signal coupling noise of each sensor pixel. The proposed detection circuit increases the voltage difference between a ridge and valley about $80\%$ more than old circuit. The test chip is composed of $160\;\times\;192$ array sensing cells $(9,913\times11,666\;um^2).$ The sensor plate area is $58\;\times\;58\;um^2$ and the pitch is 60um. The image resolution is 423 dpi. The chip was fabricated on a 0.35um standard CMOS process. It successfully captured a high-quality fingerprint image and performed the registration and identification processing. The sensing and authentication time is 1 sec(.) with the average power consumption of 10 mW at 3.0V. The reveal ESD tolerance is obtained at the value of 4.5 kV.

인터넷 트래픽을 ATM 네크워크를 통해 효율적으로 전송하기 위해 ATM 포럼에서 새로운 서비스 클래스인 GFR을 제안하였다. GFR 서비스는 VC의 최소 수율을 보장하고, 잉여대역을 연결된 VC에 공평히 제공하여야 한다. 본 논문에서는 GFR이 요구하는 최소 전송율 보장과 공평성을 향상하기 위해서 퍼지 알고리즘을 이용한 버퍼 관리 알고리즘을 제안한다. 제안된 알고리즘은 퍼지 제어기를 이용해서 새로 도착하는 패킷을 버퍼 상태와 VC의 부하에 따라 동적으로 폐기를 결정하여 버퍼 이용 효율과 GFR의 요구사항을 충족할 수 있도록 하였다. 시뮬레이션을 통해 기존의 버퍼 관리 알고리즘과 성능을 비교한 결과, 공평성과 TCP 수율 면에서 성능이 향상됨을 보였다.

Food safety has been a growing consumer concern over the last few decades, and remains a priority for consumers, the food industry, and regulatory agencies alike. Although consumer concern for food safety has increased, consumer confidence has decreased. The emphasis on food safety is related to that of preliminary risk management. The ability to collect and provide food risk information is a key element in enhancing the way food safety authorities protect consumers from risk. This review aims to investigate the current situations of international organizations, as well as several countries' systems for collecting and providing food risk information. Through the comparison and analysis of each system, this review proposes strategies to establish a systematic collecting of information and provision of infrastructure in Korea. To develop an information collection system suited to Korea's situation, it is necessary for Korea to strengthen interactions and cooperation with other trade partners through the enlargement of international networks. Such efforts on food risk communication should be made by providing high quality and clear information.

The information in physical planning field shows the socio-economic potentials of land resources while cadastral data does the physical and legal realities of the land. The two domains commonly deal with land information but have different views. Cadastre has to evolved to the multi-purpose ones which provide value-added information and support a wide spectrum of decision makers by mixing their own information with other spatial/non-spatial databases. In this context, the demands of data exchange between the two domains is growing up but this cannot be done without resolving the heterogeneity between the two information applications. Both of either discipline sees the reality within its own scope, which means each has a unique way to abstract real world phenomena to the database. The heterogeneity problem emerges when an GIS is autonomously and independently established. It causes considerable communication difficulties since heterogeneity of representations forms unique data semantics for each database. The semantic heterogeneity obviously creates an obstacle to data exchange but, at the same time, it can be a key to solve the problems too. Therefore, the study focuses on facilitating data sharing between the fields of cadastre and physical planning by resolving the semantic heterogeneity. The core job is developing a conversion mechanism of cadastral data into the information for the physical planning by DB coupling techniques.

논문에서는 스트림 데이타를 인증하는데 적합한 개선된 HORS 일회용 서명 기법을 제시한다. 스트림 인증에 일회용 서명 기법을 사용할 경우, 가장 큰 문제점은 큰 서명 크기로 인해 네트워크 오버헤드가 많다는 점이다. 제시한 기법은 기존 일회용 서명 기법 중 서명 크기가 가장 작다. 또한, 제시된 기법의 검증 연산량은 매우 작다. 스트림 인증에 적합한 기존 기법과 온라인 서명 연산량을 비교하면, HORS보다는 다소 많지만, BiBa나 Powerball보다 매우 작다. 제시된 기법에서 서명 연산은 쉽게 병렬 처리가 가능하며, 특히 비밀키를 가지지 않는 서버의 도움을 받을 수 있기 때문에, 서명 서버의 부하를 손쉽게 그리고 안전하게 줄일 수 있다.
