호텔종사원의 직무스트레스가 직무만족과 서비스 태도에 미치는 영향
배성일(Seong Il Bae) 한국관광연구학회 2012 관광연구저널 Vol.26 No.5
This work is intended to investigate how the job stress of hotel employees (role conflict, role ambiguity, and role overload) affect their job satisfaction and service attitudes(service committment and service-oriented voluntary behavior), and thus provide a fundamental material for a plan of effective and efficient personnel management. The results of this work are summarized as follows. First, regarding the relations between the job stress factors of hotel employees and their job satisfaction, ``role conflict``, ``role ambiguity``, and ``role overload`` negatively affected ``job satisfaction``. Secondly, regarding the relations between the job stress factors of hotel employees and their service attitudes, ``role conflict``, ``role overload`` negatively affected ``service commitment``, and also ``role conflict``, ``role ambiguity``, and ``role overload`` negatively affected ``service-oriented voluntary behavior``. The results means that ``role conflict``, ``role ambiguity``, and ``role overload``, perceived by hotel employees, negatively affect their job satisfaction and service attitudes. Therefore, to increase the job satisfaction and service attitudes of hotel employees, it is necessary to seek a plan to lower their job stress factors, such as role conflict, role ambiguity, and role overload.

The study was to compose relation characteristics factors of Korean restaurants with customer directivity, size, reputation, and price, conduct empirical analysis on relations between relation quality and revisiting intention, and provide fundamental materials to establish marketing strategy to domestic Korean restaurant owners and those who prepare to open business. In the result verifying the hypothesis of the research, among relation characteristics factors of Korean restaurants in hypothesis 1, reputation, price, and size appeared to give positive(+) effect on satisfaction, which showed that as reputation, price, and size of relation characteristics are high, the more satisfaction is felt. Customer directivity of relation characteristics appeared not to influence, which showed that higher customer directivity lowered satisfaction and it wasn`t significant statistically. However, customer satisfaction of relation characteristics appeared not to influence satisfaction. Customer directivity, price, and reputation among relation characteristics factors appeared to influence positive(+) effect on trust, which showed that as customer directivity, price, and reputation were higher, the more trust was felt. However, size of relation characteristics appeared not to influence, which showed that higher size lowered trust and it wasn`t significant statistically. Among relation characteristics of Korean restaurants in Hypothesis 2, customer directivity, reputation, and price appeared to influence positive(+) effect on revisiting intention but size appeared not to influence. That is, customers had higher revisiting intention as customer directivity, reputation, and price were high, revisiting intention became higher and as the size was higher, revisiting intention became lower. Among relation quality in hypothesis 3, satisfaction and trust appeared to give positive(+) effect on revisiting intention, which showed that as satisfaction and trust were higher in relation quality which customers felt, revisiting intention became higher. Hence customer desires need to be understood precisely and since even though a Korean restaurant is popular in a certain area, the revisiting intention can differ by time and position concept, reputation, customer directivity, price, and so on should be change with proper adjustment. Therefore precise education program for employee, acquisition of parking space, and proper price are considered to need detail segmentation strategies.
명령제어 서버를 이용한 IRC 악성코드 분석 및 트래픽 제어

IRC(Internet Relay Chatting)는 인터넷 채팅 서비스로서 채팅을 수행하기 위해서 IRC 서버에 접속해야 한다. 봇넷 중에는 IRC 채널을 이용하는 봇넷이 있으며, IRC 봇은 서버에 접속하는 프로그램인 IRC 클라이언트에 스크립트를 처리할 수 있는 기능이 포함되어 있다. 악성 IRC봇은 IRC 채널에서 채널 생성자가 접속자에게 특정 명령을 전송할 수 있고 클라이언트들이 해당 명령을 수행할 수 있는 기능을 악용하여 공격을 수행한다. 악성 IRC봇을 통해 발생 가능한 공격에는 트로이 목마(Trojan Horse), 백도어(Backdoor), 분산서비스거부(DDoS) 등이 있으며, 감염된 시스템이 방대할수록 공격의 강도가 증가해 공격 받는 시스템의 서비스 가용성에 문제가 발생할 수 있다. 본 논문에서는 IRC Bot으로 알려져 있는 Phorpiex와 Shadowbot의 다양한 행위 정보를 추출하기 위해 정적 분석 및 동적 분석을 수행한 결과와 인젝션기법을 언 패킹하는 방법을 제안하며, 자동화된 스크립트를 이용한 버퍼수정을 통해 서버의 명령을 제어하여 실행코드의 특정 분기로 이동할 수 있는 방법을 제안한다. Internet Relay Chatting (IRC) is an Internet chat service that requires one to connect to an IRC server to chat. Botnets that use the IRC channel and the IRC bot have the ability to process scripts to the IRC client, which is a program that connects to the server. Malicious IRC bots can exploit the ability of a channel creator to send a specific command to an IRC channel and of the clients to execute the command. There are Trojan Horse, Backdoor and DDoS attacks that can occur through malicious IRC bots. The more infected systems are, the more intense the attack may occur. In this study, we propose a static analysis and a dynamic analysis to extract various behavior information of Phorpiex and Shadowbot known as IRC Bot, and a method of unpacking the injection technique through buffer modification using an automated script, to move to a specific branch of executable code.

N/A In conventional metallothermic reduction(MR) for obtaining tantalum powder in batch-type operation, it is difficult to control morphology and location of deposits because the reaction occurs by direct physical contact between reductants and feed materials. On the other hand, a electronically mediated reaction(EMR) is capable to overcome these difficulties through the reaction by electron transfer and have a merit of continuous process. In this study an MR and EMR method has been applied to the production of a tantalum powder by sodium reduction of K_2TaF_7. As the reduction temperature increases, the particle size and yield of tantalum powder obtained by MR and EMR method is increased.

Few prior studies investigated the correlation between corporate ownership structure and environmental information disclosure. Using environmental index disclosure in GRI (Global Reporting Initiative) reports of the Korean companies, the study examines the effects of ownership structure on the magnitude of environmental information disclosure. A total of 220 firm-years during 2013-2016 period are analyzed. The empirical results of the study indicate that the institutional and foreign investors’ ownership have positive correlations with environmental information disclosure, while the executives' within board of directors has a negative correlation. The ownership by largest shareholders including those with special interests shows no significant relationship with the environmental information disclosure.

The distribution control of refrigerant flow is one of the basic technique to enhance system efficiency. However, if engineers forget to control the refrigerant flow speed in all operation range, refrigerant flow mal distribution becomes a noise source. The refrigerant flow noise should be checked and controlled at the lowest air flow mode which is the most silent mode and frequently used in night time.
