The purpose of this study was to examine the effect of perceived justice associated with service recovery on perceived service quality, and the relationships among perceived service quality, customer satisfaction and behavioral intentions in online apparel shopping contexts. Justice theory provided the theoretical framework for this study. The research strategy employed an online survey methodology. Online shoppers (N=669) who had experiences in service failure and dissatisfactions completed a questionnaire. The model of the study was tested by structural equation modeling (SEM) and the results of SEM revealed positive effect of perceived justice regarding service recovery on perceived service quality, positive effect of perceived service quality on customer satisfaction, and positive effect of customer satisfaction on behavioral intention. The results of this study have implications for online retailers. Online retailers need to understand the importance of service recovery by which service failures are managed.

Service Level Agreement (SLA) is a service providing scheme by a service class agreement between a user and a service provider SLA allows that a user can select an expected service class in various service classes provided from a service provider. Recently, SLA management is adapted to support the end-to-end Qos for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satisfaction for users. In this paper, we propose a dynamic Qos management scheme by IP traffic class controlling based on SLA in B3G networks. Also, to manage dynamic traffic service, we consider Differentiated services (Diffserv) mechanism for the resource management by SLA. An If service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dynamic end-to-end Qos. Hence, in this paper, we consider the buffer threshold scheme for controlling traffic loads and the traffic level control scheme for implementing the dynamic traffic management by the SLA.

In recent years, public area CCTV has also begun to become more popular in the Korea. 2011, Korea's Ministry of Public Administration and Security has recommended that other local governments set up an integrated CCTV control center in each of their districts. The ministry was planning to make it compulsory for local governments to install an integrated CCTV control center by 2015. More than 570,000 public cameras are managed by public agencies and local government offices. Currently, the integrated CCTV control center is playing a very positive role in fighting crimes in the district particularly through its liaison with the district police. The CCTVs were operated by a several different agencies and departments in the district, resulting in considerable redundancy in public service, inefficiency and delays in response to crimes, and other emergency situations. Therefore, Control Center should be operated lawfully and efficiently. CCTV Control Center will be managed by three ways: (1) IT Governance through cooperation with civil areas (2) by regulated with proper laws and (3) managed by proper guideline and personal training.

Vendor-managed inventory(VMI) is a supply chain strategy to improve the inventory turnover and customer service in supply chain management. Unfortunately, many VMI programs fail because they simply transfer the transactional aspects of placing replenishment orders from customer to vendor. In fact, such VMI programs often degrade supply chain performance because vendors lack capability to plan the VMI operations effectively in an integrated way under the dynamic, complex, and stochastic VMI supply chain environment. This paper presents a decision support system, termed DSSV, for VMI in the retail supply chain. DSSV supports the market forecasting, vendor's production planning, retailer's inventory replenishment planning, vehicle routing, determination of the system operating parameter values, retailer's purchase price decision, and what-if analysis. The potential benefits of DSSV include the provision of guidance, solution, and simulation environment for enterprises to reduce risks for their VMI supply chain operations.

본 논문에서는 내장형 소프트웨어 시스템, 특히 로봇 소프트웨어를 위한 self-managed 소프트웨어 개발 프레임워크로서 SHAGE 프레임워크를 제안하였다. SHAGE 프레임워크는 소프트웨어를 실행시간에 동적으로 변경시킬 수 있도록 지원하는 여러 모듈로 구성되어 있다. Observer가 외부 상황을 관찰하고 관찰된 상황이 Architecture Broker로 전달되면 후보 아키텍처 재구성 전략을 검색하고 Component Broker가 구체화 컴포넌트들을 검색한 후 상황에 적절한 아키텍처 재구성 전략과 컴포넌트 구성을 Decision Maker가 선택한다. Reconfigurator가 선택된 전략과 컴포넌트 구성을 기초로 로봇의 아키텍처를 재구성한다. 적응행위를 Evaluator가 평가하고 그 결과를 Learner가 축적하여 나중에 Decision Maker가 사용할 수 있게 한다. 프레임워크의 효용성을 확인하기 위해서 실제 로봇을 이용한 사례연구를 수행하였고, 이 실험을 통해 적응 과정을 확인하였다. 로봇은 상황과 사용자의 피드백에 적응하였다.

Although e-commerce is growing fast, e-commerce consumers are still under higher risk and uncertainty in the comparison of the traditional commerce's. Consumer review boards of online shopping malls are good measures to help buyer's decision making, and should be managed effectively by sellers. We formulate the research model on consumer trust formation on seller managed web review boards on the background of previous literatures on e-WOM and trust. Our data analysis with 368 samples shows seller's reputation, e-service quality, perceived reviewer's benevolence and ability have significant positive effect on the trustworthiness of the board. Product involvement shows weak negative moderation effect on the relationship between perceived reviewer's benevolence and trustworthiness of review boards.

Recently, Vendor Managed Inventory(VMI) has been commonly recognized as one of the supply chain application that delivers clear value to the sectors of electic & electronic components. VMI is a process in which a supplier generates orders for its distributor based on demand information sent by the distributor. VMI is providing the benefits of smoother demand, lower inventories(work in process, safety stock) and reduced costs. This study focused on improvement of safety level inventory efficiency by VMI. The results indicated that VMI allowed the company to serve its customers more surely and efficiently.

This study aimed at evaluating current sanitation management performances in Korean-Food restaurants by their operation types and to develop sanitary training posters based on the risk factors, in an attempt to improve the level of sanitation management in Korean food service facilities. Eighteen Korean-food restaurants that are managed by franchisor, franchisees as well as self-managed with large-scale and small-scale restaurants in Seoul and Gyeonggi-Do, were evaluated by on-the-spot inspectors with an auditing tool consisting of three dimensions, nine categories and thirty four items. Data were analyzed using SPSS. The total score of each group showed that restaurants managed by franchisees ranked the highest (59 out of 100 points), while self-managed, small-scale restaurants ranked the lowest (44 out of 100 points). In the categorization of sanitation management compliance, the dimensions of food hygiene during production recorded the lowest compliance rate of 47.7% (22.89/48.0 points) followed by the dimension of environmental hygiene 59.3% (20.17/34.0 points) and personal hygiene 60.5% (10.89/18.0 points). This indicated the need for urgent improvement. The items which showed the lowest compliance rates were 'proper thawing of frozen foods' (0%), 'notifying and observing heating/reheating temperature' (6%), 'using of hand-washing facility and proper hand-washing' (33%), 'monitoring temperature of frozen-foods and cold-foods' (35%), and 'prevention of cross-contamination' (36%) among thirty four items. Self-managed, small-scale restaurants, in particular, needed to improve sanitary practices such as 'sanitation education for employee', 'verifying the employee health inspection reports', 'storing food on the shelves 15 cm distance away from the wall', 'suitability of ventilation capacity of hoods' and 'cleanliness of drainage'. On the basis of the findings of this study, we developed sanitary training posters, especially for small-scale restaurant operators. This could be an effective tool to educate food service employees on sanitary knowledge and principles and could be used to improve the existing sanitary conditions in Korean food service facilities.

사이버공격이 지능화되고 고도화되면서 이를 체계적으로 대응하기 위한 보안관제센터(SOC : Security Operations Center)의 중요성이 높아지고 있고, SOC의 규모와 그 수도 늘어나고 있다. 각 기관 및 조직에서 다양한 사이버보안 표준을 활용하여 업무 절차를 만들어 사용하고 있으나 SOC는 자체 인력보다는 보안관제전문기업과 협업하는 경우가 많아 SOC환경에 맞게 개선이 필요하다. NIST 사이버보안 프레임워크(CSF : Cybersecurity Framework)와 정보보호관리체계 그리고 보안관제전문기업의 업무절차를 비교 분석한 결과 NIST CSF가 보안관제에 적용하기 용이한 프레임워크이나 국내 SOC에 적용하기 위해서는 SOC의 운영 및 관리 부분이 추가적으로 보완될 필요가 있다. 따라서 본 연구에서는 NIST CSF를 참조 모형으로 하여 SOC환경에 필요한 관리적 항목을 도출하였으며 각 항목에 대한 필요성, 중요성, 용이성을 델파이 조사방식으로 검증하고 개선된 사이버보안 프레임워크를 제안하였다.
