In this paper, I raise objections to Sungsu Kim's argument that Sartorio's hard-line reply to the manipulation argument fails. In attacking Sartorio's argument, Sungsu Kim claims that there are two problems with Sartorio's. I argue that Sungsu Kim's argument fails by responding to these two problems. With respect to the first problem, I provide a new example of dilution of responsibility. With respect to the second problem, I argue that, contrary to what Sungsu Kim assumes, for Sartorio's argument to succeed, our intuition that Ernie is responsible in the Lightning Strike Scenario does not have to be as strong as our intuition that Ernie is not responsible in the Diana scenario.

At the most recent, IPTV service is increasing, which isa communicative broadcasting fusion service that provides various multimedia contents interactively followed by user's request through super high-speed internet. For IPTV user service with high mobility, IPTV user's enrollment is essential. However, IPTV service provided to mobile users can't provide the certification of mobile user securely. This paper proposes light user certification protocol which can certificate mobile users by attaching RFID to IPTV STB for secure awareness of mobile users who get IPTV service. The proposed protocol prevent reply attack and man-in-the-middle attack from happening oftenin a wireless section by transmitting the result value hashed by hash function with both its' ID and random number received from tag after tag transmits random number which generated randomly in the process of certification of mobile user to IPTV STB.

The force majeure in the international sale of goods has been widely used regarding liability and settlement of disputes in the event of breach of contract due to circumstances beyond the control of the parties. The purpose of this study is to examine the judgment criteria and cases concerning on force majeure in the application of FTA preferential tariffs. In order to achieve this purpose, this paper uses a literature review and case analysis on exceptional circumstances under the Korea·ASEAN FTA and the Korea·EU FTA. This study, this paper provides several implications for companies seeking preferential tariffs regarding the Korea·ASEAN FTA and the Korea·EU FTA. Korean companies are subject to the following: confirm the denial article of FTA preferential tariffs stipulated in the Korea·ASEAN FTA and the Korea·EU FTA, consider the judgment criteria on exceptional circumstances of customs authorities, confirm the extension criteria on the validity period of certificate of origin, confirm the reply criteria of verification result of the customs authorities of the exporting country, and confirm the violation of the principle of good faith for unrequested action on reply of verification result of customs authorities.

Most people today search for information on the Internet about the goods or services they want to purchase and then assess the replies posted by other people who have experience with those goods or services. These replies serve as an important reference point that can affect purchase decisions. Replies are divided broadly into two types: first, market normative replies about whether a person experiences satisfaction with (or more than) the price paid for goods or services (positive) or not (negative); and the second is non-market normative replies about whether the goods or service provider morally deserves the profits gained from providing them (positive) or not (negative). Previous studies on replies have focused on market normative replies (whether the food is delicious), and there have only been some studies on the effect of non-market normative replies (the owner is morally good). This research was undertaken to re-examine the effect of market normative replies identified by previous studies in a restaurant visit intention evaluation (Experiment 1), to examine the effect of non-market normative replies not investigated in previous studies (Experiment 2), and to compare the effect of market normative replies and non-market normative replies (the meta-analysis) In conclusion, restaurant visit intention was stronger when market normative replies were positive (delicious) than when they were negative (not delicious) (Experiment 1). Furthermore, restaurant visit intention was stronger when non-market normative replies were positive (the owner is moral) than when they were negative (the owner is immoral) (Experiment 2). On the other hand, it was found that restaurant visit intention was stronger when non-market normative replies were positive than when market normative replies were positive, and restaurant visit intention was weaker when non-market normative replies were negative than when market normative replies were negative. This implies that people are more likely to be affected by non-market normative replies than market normative replies. In addition, this study suggested that the mood changed more before and after checking non-market normative replies than before and after checking market normative replies, and due to this difference, people could be affected more by non-market normative replies than market normative replies.

최근들어 Radio Frequency Identification(RFID) 태그가 다수의 상품에 부착되고 여러 분야에 적용되기 시작했지만, 편리성이나 비용문제로 인해 인증과 암호화 같은 보안기능은 적용되지 않고있다. 보안 기능이 없는 RFID 시스템은 개인정보 노출, 불법 리더의 접근, 위조 태그의 남용과 같은 심각한 부작용을 초래하지만, 태그 자원의 제약으로 인해 보안기능을 적용하기가 쉽지않다. 현재 여러 기술을 따르는 RFID 시스템 중 EPCglobal 의 EPC Class 1 Generation 2(C1G2) 는 산업계의 여러 분야에서 특히, supply-chain 모델에서 사실상 국제표준으로 여겨진다. 본 논문에서는, RFID 보안 프로토콜 중 EPC C1G2 메커니즘의 Inventory 과정에서 태그가 리더를 인증하는 기법을 제안한다. C1G2 시스템에서는 인증되지 않은 리더의 태그 액세스가 가능한데, 이는 태그의 리더 인증으로서 차단될 수 있다. 또한, EPC C1G2 태그-리더 간의 상호인증 기법을 제안한다. 이 과정에서 태그 ID 는 노출되지 않고 전송되며, 태그 인증을 통해 태그 위변조를 방지할 수도 있다. 제안 메커니즘은 태그를 식별하는 절차에서 인증을 위해 프로토콜 패스 수의 증가가 없다. 다만 리더와 태그에서 Inventory 과정의 ACK command 와 태그의 reply 구현에 약간의 수정을 필요로 한다.

This paper describes an study electric injection system for diesel engines. It is needed effective fuel injection which controls the solenoid valve of fuel pump. To solve this, this paper proposes DCC-PWM method which can realize fast reply and low holding current for solenoid valve on/off. For the proposed design method, simulation tools of ACSL are used to analyze the system. And the single-chip microcomputer is used to reduce the size of controller and to improve flexibility. And the system's validity can be verified through the experimental results.

The chatter to raise grinding operating is reduce the precision and the quality. In this study, In reply to AE signal and the normal force generated in the grinding operating were measured (1) the amplitude in the mathematical model of the normal force is the form as to transform an exponential (2) the chatter growth is minus point of an exponent. (3) From the observed wheel aspect after the chatter growth, it was to investigated the concern of the chatter growth and the wheel life.

In a previous paper I argued that the denial of the uncontested principle results in the denial of modus ponens. In his reply Byeong Deok Lee explicitly says that he does not deny the validity of modus ponens though he still does not accept the uncontested principle. In this paper I show that his view is untenable.

This study aims to develop Semangum tourism package that can be most suitable for the tourist. The data were obtained by a survey carried out between August, 17 and August, 24, 2009 with a sample of latent tourist of Semangum. Conjoint analysis has been used to estimate the relative importance of attributes. Four main attributes and two or three attributes levels for each determinant were chosen for conjoint analysis. Eleven model package were made using fractional factorial design, and presented to the latent tourist, who were asked to reply in order of their like. Results show that the most important attributes for tourist were in order of cost, connected tourism, accommodation and report activity.

This paper aims to explore the institutional difference between Tsinghua University Science Park (TusPark) in Beijing, and business incubator of Research Institute of Tsinghua University in Shenzhen (RITS), and to examine how the difference leads to different new product performance for tenants. In doing so, we use survey methodology to investigate the innovation sources, university linkages, and innovation outputs of tenants in TusPark and RITS. We found that tenants in RITS reply more on "market-driven" knowledge sources for innovation: including knowledge from customers, suppliers, and competitors. The empirical findings suggest that the technology support provided by RITS and the high dependency on "market-driven" knowledge sources jointly contribute to the better new product performance for tenants in RITS.
