Life log started with the simple purpose of recording or sharing mainly data regarding one's personal life, but with the introduction of advanced specialized analytic methods by many corporations, a new type of business based on the life log recently emerged, with an aim of improving the quality of people's personal lives. In spite of the indispensable advantages, however, personal health lifelog service brings critical challenges that cannot be avoided from user side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the revitalization of personal health lifelog services. In this paper, we propose an information security reference model for the personal health lifelog services. Our proposal can contribute to increase the related industry to cultivate new market by suggesting the clear announcement of the guidelines using privacy protection reference model for user-specific healthcare services which uses personal lifelog.

Many countries, especially ICT powers, are supporting IoT-based technology at a national level and this technology is actively being researched in the businesses and research institutes in an aim to develop technology and create an ecosystem. Roads in the Seoul city are building public facilities based on IoT to provide various services and conveniences for the users. However, for the full-fledged introduction and development of IoT, there are many cases where infringement on security and privacy and threat for life and safety happen. Also, as the IoT environment includes various environment technologies such as the existing sensor network, heterogeneous communication network, and devices optimized for the IoT environment, it inherits the existing security threat and various attack techniques. This paper researches the attribute based encryption technology for safe communication in the IoT environment. The data collected from the device is transmitted utilizing the attribute based encryption and by designing the key generation protocol, grades and authorities for the device and users are identified to transmit safe messages.

This paper is to evaluate the informational direction, current situations and ERP establishment concerning constructing industry, to present the right directions, implemented cases for implementing constructional ERP, also to suggest the effect, influence, problems and shootings in constructional ERP arena. The constructing industries in korea are facing great turning point because of the huge corruptions currently happened and forcing to open the market in 1997. Attempting to establish Computer Integrated construction system (ERP) by breaking down constructing cost, improving quality, operating rapid and effective construction to enhance productivity, it is hard to achieve the goal with only inter-contractor's establishment. Constructing industries are integrated ones, consisted of many organizations for instance ordering agencies, contractors, subcontractors, material vendors, etc. and use various information formats such as texts, graphics, drawings. I dare suggest that implementation of constructional CALS including EDI/EC, GIS is tile only solution to control the information systematically generated in whole stages from planing, designing, constructing through maintenance, and to supply or switch the information.

Various applications are widely developed for smartphones to meet customer's needs. In many companies, messenger's typed interactive systems have been studied for business marketing, advertising and promotion to provide useful services for the customers. Such interactive systems are usually called as "Chatbot". In Chatbot, duplicated responses from Chatbot could occur frequently, and these make one lose interest. In this paper, we define a case that the response of Chatbot is duplicated according to the user's input, and propose a method to reduce duplicated responses of Chatbot. In the proposed method, we try to reduce duplication responses through a new duplication avoidance algorithm by building multiple tables in a database and by making combinations of user's input and its response in each table. In our experiments, the proposed method shows that duplicated responses are reduced by an average of 70%, compared with the existing method.

Better utilization of the knowledge of employees in any organization has long been accepted as a vital component of a corporation's competitiveness. This has been considered even more important in the construction industry due to the dynamic and intermittent nature of construction projects. With the rapid advance of network technologies during the last decade, construction companies quickly shifted their focus of knowledge management to interactive online repositories. However, the efforts of leveraging organizational knowledge has remained fragmented in the construction industry until recent years. In addition, companies have begun to realize that actual returns on this investment in network technologies would be far less than initial expectations if online efforts do not incorporate companies' general offline knowledge management efforts, which are done without the use of computer network. Thus, this paper focused on assessment of implementing current Lessons-Learned Systems at the large construction companies in Korea to provide the foundation for developing a renovated conceptual Lessons-Learned System model.

Lately, intrusive incidents (including system hacking, viruses, worms, homepage alterations, and data leaks) have not involved the distribution of an virus or worm, but have been designed to acquire private information or trade secrets. Because an attacker uses advanced intelligence and attack techniques that conceal and alter data in a computer, the collector cannot trace the digital evidence of the attack. In an initial incident response first responser deals with the suspect or crime scene data that needs investigative leads quickly, in accordance with forensic process methodology that provides the identification of digital evidence in a systematic approach. In order to an effective initial response to first responders, this paper analyzes the collection data such as user usage profiles, chronology timeline, and internet data according to CFFPM(computer forensics field triage process model), proceeds to design, and implements a collection application to deploy the client/server architecture on the Windows based computer.

This study examines the implications of special items (SI) for future earnings using quarterly Korean data over the period from 2011 to 2014. Due to the lack of identification of SI in Korea, I choose several items as special items if they are material and non-recurring items following prior studies. Then I regressed seasonally-differenced future earnings on positive and negative SI and found that their effects on future earnings were different. While negative SI are explained by inter-period expense transfer, positive SI are not well-described by traditional prototypes. Next, I regressed seasonally-differenced future earnings on negative SI sub-types as they are heterogeneous in nature and have differing implications for future earnings. While PPE impairments and intangibles impairments are partly explained by the inter-period expense transfer, unspecified loss of other loss items are not. Interestingly, these effects are attenuated or disappear in the Kosdaq market when the markets are divided into the Kospi and Kosdaq markets.

Emotional labor may lead to service failure in service industries. Managers of an organization or a company can contribute to service recovery by reducing stress related to emotional labor. The aim of this study is to identify the antecedents and consequences of service recovery in respect of emotional labor. Data was surveyed from frontline employees to achieve the research purpose. The hypotheses were examined empirically using statistical tools. Results are as follows. First, surface acting had a negative impact on service recovery performance and deep acting had a positive impact. Second, empowerment and motivation had an influential relationship positively on service recovery performance. Third, service recovery performance was negatively related to intention to quit. In conclusion, managing employees' emotional labor strategies and work environment will bring high service recovery performance and low intention to quit.
