Sales Force Automation (SFA) is a strategic information system and one of the components of operational CRM system. SFA supports salespeople's activities such as selection of potential customers, creative value proposition, after-sales services, etc. SFA is increasingly used in many companies because it has the advantages to raise the salespeople's productivity by developing forecasting ability, value proposition ability, after sales service ability etc. Many researches have shown that implementation of SFA leads to the increase of salepeople performance, organizational performance, and quality of customer relationship. However, Some prior studies have discussed on the SFA implementation failure and pointed out that one of important causes of this failure is salespeople's resistance to SFA. Although many researches explain SFA acceptance phenomenon using Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB), these researches didn't deeply investigate the salespeople's resistance to SFA. Therefore, this study focuses on the factors influencing salespeople's resistance to SFA and the relationships among these factors. This study identified three factors (salespeople's perceived loss of power, perceived loss of autonomy, and perceived time and effort waste) influencing salespeople's resistance to SFA. The hypotheses testing results showed that salespeople's perceived loss of power and perceived time and effort waste significantly increased salespeople's resistance to SFA. And salespeople's perceived loss of power plays a mediating role between perceived loss of autonomy/perceived time and effort waste and salespeople's resistance to SFA. At the end of the paper, theoretical and managerial implications of this study and the limitations and future research directions are discussed.

This study is to review the Joseon government's attempt to recover the tariff autonomy lost in the course of entering into the unequal treaty with then-Japan government, as well as the practical effort to realize such an attempt. Among other attempts, the Joseon government ① began imposing tariffs starting September 1878 by establishing Dumopo Customs Office in Busan, ② dispatched on April 1881 a group of investigators to the competent authorities to review and look back the Joseon's tariff system against Japan and ③ entered into a tariff negotiation with then-Japan government on September 1881 with the emissary (Susinsa) Byeong-ho Jo representing the Joseon government. A series of these attempts, in line with each other, represents the Joseon government's ceaseless, constant effort to recover the tariff autonomy, which is what this study intends to review from the modern-day perspectives. Authored by Byeong-ho Jo to capture an advantageous position in the 1881's tariff negotiation against then-Japan government, 「Joilseui」 successfully represented the Joseon government's position on matters of ① the Japanese tax-autonomous district in Korea, ② defining tariff rates, ③ use of Japanese Yen for payment of tariffs, ④ effective period of the treaty and ⑤ export restrictions on grains. Failure of the Joseon government's attempt to recover the Tariff autonomy was attributable not only to, as 「Joilseui」 defined, ① governments' non-cooperative attitudes on the negotiation table, ② lack of authorities that the entrusted bodies had, ③ import tariffs defined high and ④ export restrictions on grains and red ginseng, but also to loss of the tariff autonomy in 1876 and the 1881's negotiation broken down that were plotted by then-Japan government's invasive policy.

For the vast majority of geostationary satellites currently in orbit, station keeping activities including orbit determination and maneuver planning and execution are ground-directed and dependent on the availability of ground-based satellite control personnel and facilities. However, a requirement linked to satellite autonomy and survivability in cases of interrupted ground support is often one of the stipulated provisions on the satellite platform design. It is especially important for a geostationary military-purposed satellite to remain within its designated orbital window, in order to provide reliable uninterrupted telecommunications services, in the absence of ground-based resources due to warfare or other disasters. In this paper we investigate factors affecting the robustness of a geostationary satellite's orbit in terms of the maximum duration the satellite's station keeping window can be maintained without ground intervention. By comparing simulations of orbit evolution, given different initial conditions and operations strategies, a variation of parameters study has been performed and we have analyzed which factors the duration is most sensitive to. This also provides valuable insights into which factors may be worth controlling by a military or civilian geostationary satellite operator. Our simulations show that the most beneficial factor for maximizing the time a satellite will remain in the station keeping window is the operational practice of pre-emptively loading East-West station keeping maneuvers for automatic execution on board the satellite should ground control capability be lost. The second most beneficial factor is using short station keeping maneuver cycle durations.

Objectives: Depressive disorder (DD) is a complex disease, and the assessment of work ability in patients with DD is also complicated. The checklist depression (CDp) has recently been developed to support such work ability assessments and has been recommended for implementation in insurance medicine, starting with an analysis of the organisational and social contexts. The aim of this study was to identify the potential facilitators and barriers in the use of the CDp by insurance physicians (IPs) during work ability assessments of employees on sick leave due to DD. Methods: A qualitative research was conducted based on semi-structured interviews. The participants were IPs with at least one year of work experience in performing work ability assessments. The interviews were audiotaped, transcribed and analysed qualitatively. Results: Ten IPs (7 males, 3 females; mean 53 years) were interviewed. Important facilitators, which emerged for use of the CDp, were an oral introduction for colleagues and staff, support from management, valuing the increased transparency in work ability assessments with using the CDp, having adequate time for assessments as well as modification of the appearance (colour, plasticised form) and content (clarifying aspects of the examples) of the assessment tool. The fear of the loss of autonomy, lack of added value of the CDp, high workload, inadequate instructions and lack of time were mentioned as barriers. Conclusion: Adequate introduction to the use of CDp and the fear of the loss of autonomy of IPs need special attention in planning its implementation.

The purpose of this study was to investigate the job stress factors of aircraft composite material part manufacturing workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Two hundred and fifty workers participated in this study, and among them 204 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The results showed that the stress level of the six job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation was relatively higher than that of other industry workers. Generally, all eight job stress factors showed higher stress with temporary workers than with permanent workers, and especially job autonomy, job insecurity, organizational system, and unfair compensation factors showed statistically significant differences (p<0.05). Since the temporary workers are insecure with their job, weak position in organization, having little self-control for the job and lower pay level than that of permanent workers though the job is as same as permanent workers', the stress level of above job stress factors would be much higher than that of the other factors. The group of unsatisfactory with workplace showed higher job stress than group of satisfactory with workplace in all job stress factors, as expected, at the statistically significance level (p<0.05). From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Also the job stress management program can be implemented to improve the work efficiency and the workers' quality of life.

현재 이동 컴퓨팅 환경에서 이동 호스트가 사용하는 캐쉬는 전력의 한계와 제한된 대역폭이라는 단점을 보완할 수 있는 중요한 장치로서 사용된다. 하지만 서버 데이터와의 일관성을 유지해야 하는 부담을 가지고 있다. 본 논문에서는 선택적 캐쉬 일관성 유지 기법을 제안한다. 서버는 캐쉬 상태 테이블, 데이터 접근 테이블을 유지하여 이동 호스트에서 미래 사용성이 높은 데이터에 대한 선별을 통해 효율적인 방송을 가능하게 한다. 또한 오랜 접속 단절 이후에 연결된 이동 호스트의 요청에 따라 서버가 보관하고 있던 지난 방송 정보를 전달하고 비동기적인 방송을 수행함으로써 다수의 캐쉬 데이터가 버려지는 것을 방지하고, 최신의 데이터를 보유할 수 있도록 한다. 따라서 이동 호스트는 서버에 대한 의존도를 줄일 수 있게 되어 자치성 증대라는 효과를 얻을 수 있음이 실험을 통해서 보여진다.

In this paper, we have designed the integrated wire and wireless P2P framework using mobile agents to share efficiently resources as media file. Most of the P2P applications are used on the wire network. We propose the integrated wire and wireless P2P framework. Proposed P2P platform is based on JXTA of Sun Microsystems. But JXTA is pure peer-to-peer network model, so it sends message other peers as broadcast style to request resources. In this way, there are some problems as massage overload, bandwidth loss, etc. In order to solve this problem, we propose a hybrid peer-to-peer network model using mobile agent. Proposed scheme also solve existing hybrid pEp model's flaws which have the delay and low rate due to concentrated server. In proposed scheme, mobile agents that have autonomy and mobility are used to search the location of resources. Besides, mobile agents could solve the loss problem of the search result. To improve P2P QoS(Quality of Service), we could monitor peer's state information using PIP(Peer Information Protocol) of JXTA.
