In the UMTS (Universal Mobile Telecommunication System), which is one of 3G mobile communication standards, the protocol called UMTS AKA (Authentication and Key Agreement) is used to authenticate mobile stations. However, the UMTS AKA protocol has some weakness, including network bandwidth consumption between a SN (Serving Network) and a HN (Home Network) and SQN (SeQuence Number) synchronization. In this paper, we propose a new improved protocol for UMTS that overcomes UMTS AKA weakness. Our protocol solves the privacy problem caused by IMSI (International Mobile Subscriber Identity)'s disclosure and provides perfect forward secrecy using ECDH (Elliptic Curve Diffie Hellman).

With the development of smart grid technologies, a user can use the secure and reliable power services in smart gird environments. However, the users are not secure against various potential attacks because the smart gird services are provided through the public channel. Therefore, a secure and lightweight authentication and key agreement scheme has become a very important security issue in smart grid in order to guarantee user's privacy. In 2019, Zhang et al. proposed a lightweight authentication scheme for smart gird communications. In this paper, we demonstrate that Zhang et al.'s scheme is vulnerable to impersonation and session key disclosure attacks, and then we propose a secure authentication and key agreement scheme for smart grid environments without tamper-resistant devices. Moreover, we perform the informal security and the BAN logic analysis to prove that our scheme is secure various attacks and provides secure mutual authentication, respectively. We also perform the performance analysis compared with related schemes. Therefore, the proposed scheme is efficiently applicable to practical smart gird environments.

This paper intends to review the qualifications of arbitrator, the disclosure of disqualifications by arbitrator, the challenge grounds of arbitrator, and the challenge procedure of arbitrator under the arbitration laws and rules. There are no provisions for the qualification of arbitrator in the UNCITRAL Model Law on International Commercial Arbitration. Under the UNCITRAL Model Law on person shall be precluded by reason of his nationality from acting as an arbitrators. Under the UNCITRAL Model Law when a person is approached in connection with his possible appointment as an arbitrator, he shall disclose any circumstances likely to give rise to justifiable doubts as to his impartiality or independence. An arbitrator, from the time of his appointment and throughout the arbitral proceedings, shall without delay disclose any such circumstances to the parties. Under the UNCITRAL Model Law an arbitrator may be challenged only if circumstances exist that give rise to justifiable doubts as to his impartiality or independence, or if he does not possess qualifications agreed to by the parties. Under the UNCITRAL Model Law the parties are free to agree on a procedure for challenge an arbitrator. Failing such agreement, a party who intends to challenge an arbitrator shall send a written statement of the reasons for the challenge to the arbitral tribunal within 15 days after becoming aware of the constitution of the arbitral tribunal or any circumstance that give rise to justifiable doubts as to his impartiality or independence. Unless the challenged arbitrator withdraws from his office or the other party agrees to the challenge, the arbitral tribunal shall decide on the challenge. In conclusion, an arbitrator has a responsibility not only to the parties but also to the process of arbitration, and must observe high standards of conduct so that the integrity and must observe high standards of conduct so that the integrity and fairness of the process will be preserved.

The purpose of this research is to analyze the motivations for mergers and the disclosure effects before and after two parties, which have a parent and subsidiary relationship, submit a merger agreement. The results of analysis show that the main aims of a merger between the two parties are to enhance the efficiency and the competitive power of the companies and to diversify their business lines. Efficiency increment plays an important role in a merger. A merged corporation has realized positive abnormal returns before and after a merger. Business diversification has brought the highest cumulative average abnormal returns due to the disclosure effects.

The purpose of this study was to identify the level of HIV/AIDS related knowledge and attitudes of Korean childbering women. The subject were 1152 Korean women who were living in the Seoul area and whose age was between 17-50 years. Data was collected by self reporting with a questionnaire of 57 items developed by the researcher. The reliability of the instrument for the HIV/AIDS related knowledge and attitudes were Cronbach's alpha. .6954 and .7987 respectively. The results were as follows: The mean age of the subjects was 26 years and 46.8% of them were married. The mean score for HIV/AIDS related knowledge was 14.7 out of a possible maximum score of 22. The correct answer rate for HIV/AIDS related knowledge was between 87.0-94.1% for the risk factors. and 36.4-54.8% for the transmission mode. Even though 87% of the subjects knew that homosexuals are risk group for HIV/AIDS. only half(55.8%) of the subjects answered that anal sex is the transmission mode. And only 57% of the subjects knew that HIV/AIDS transmission is possible through heterosexual contact. Their agreement level for attitudes was in order of communal coping (95%). pregnant women protection (94%). Problem appraisal (82%). patients isolation(68%). and disclosure of infection(67%). It was shown that the group who had a pregnancy (t=2.07, p=.039), used contraceptives (t=2.57, p=.OO1). and the group of college level graduates(t=3.61, p=.000) had a higher level of HIV/AIDS related knowledge. The agreement level of pregnant women protection. patient isolation. and problem appraisal were higher in the group of having had a pregnancy, having used contraceptives. and the group over 30 years of age. It was concluded that Korean childbearing women were quite knowledgeable about the risk factors but confused about the transmission mode. especially heterosexual contact. and they showed responsive attitudes to the HIV/AIDS issues considering the 339 infected cases in Korea. They preferred isolation of patients and communal coping as behavioral attitudes. Therefore it can be suggested that a HIV/AIDS prevention program should be focused on transmission mode.

For a variety of reasons, the number of medical disputes is continuously rising. Due to the intrinsic qualities of medical treatments, one would find it more apt to subject medical disputes to general conflict resolution procedures rather than to once-for-all decisions under legal suits. To address the increasing medical disputes with greater professionalism and efficiency, the Medical Disputes Mediation Act was enacted and a medical dispute mediation system put in place, while drawbacks have been blamed to both. The current mediation procedures require the respondent's agreement as a disclosure requirement. A reasonable improvement to this would be to amend the regulation of agreement supposition, or to enforce procedural participation only to public health facilities managed by the national or regional government. Furthermore, small claims cases of 20 million KRW or less in claim may be considered for conciliation-prepositive principle. The concentration on small claim medical disputes is a phenomenon that can be addressed by carrying out maximum authentication commissions or similar measures, one of the solutions by enhancing the public trust in the Korea Medical Dispute Mediation and Arbitration Agency. The proper management of medical authentication teams is one way to address the existing problems in the authentication system. For this, the number of team members shall be increased under more flexible authentication procedures. All indemnity resources for medical accidents of force majeure must be borne by the Government, for it is the body principally responsible for social compensation. Placing this cost on the establisher of the subject medical facility holds the possibility of violating fundamental rights. While the costs for subrogation payment system for damages may be borne by the healthcare facility establisher, a deposit-based system must be created for cases in which the facility shuts down, without holding the responsibility for accident cause. Such change to a deposit-based system will evade the controversies of unconstitutionality, etc.

This study aims to find the causal relationship between the effects of apartment inhabitants' life management and administrative management on housing satisfaction. The study results are as follows. Firstly, life management showed to have a positive effect on life satisfaction. In other words, the better the management of public order and facilities, the higher the satisfaction of housing satisfaction. Thus, the principal agent of management needs to increase inhabitants' housing satisfaction through education and training on developing life management techniques. Secondly, administrative management showed to have a positive effect on life satisfaction. Thus, the more accurate the completion documents and management transfer process necessary for administrative management, the higher the cost-cutting effects of accounting, construction, and service contracts, the more transparent the resident agreement process in accordance with management policies, the more transparent the election process of building representatives and resident representatives, and the higher the effects of energy saving, the higher the housing satisfaction of inhabitants. This revealed that the principal agent of management needs to increase housing satisfaction through education and training on developing administrative management techniques because the level of administrative management had a positive effect on housing satisfaction. As a result, in order to create reliability between inhabitants and the principal agents of management, the transparency of administrative management such as document disclosure must be ensured, thus improving the housing satisfaction of inhabitants.

This paper is to research the powers and interim measures of the arbitral tribunal in the arbitral proceedings of the international commercial arbitration under arbitration legislation and arbitration rules including the UNCITRAL Model Law and Arbitration Rules. The powers of the arbitral tribunal may be found within the arbitration agreement or any arbitration rules chosen by the parties, or the chosen procedural law. The power of the arbitral tribunal to decide its own jurisdiction is one of the fundamental principles of international commercial arbitration. It is a power which is now found in nearly all modern arbitration and rules of arbitration. Where an arbitral tribunal has been appointed then it will usually have the power to proceed with the arbitration in the event that a party fails to appear. It cannot force a party to attend but it may sanction the failure. While the arbitral tribunal can direct the parties to attend and give evidence the arbitral tribunal has no power to compel a party to give evidence. The arbitral tribunal may continue the arbitration in the absence of the party or its failure to submit evidence and make an award on the evidence before it. Under most of arbitration legislation and arbitration rules, the arbitral tribunal has the power to appoint experts and obtain expert evidence. The power to order a party to disclose documents in its possession is a power given to the arbitral tribunal by many national laws and by most arbitration rules. The arbitral tribunal cannot, however, compel disclosure and in the case where a party refuses to disclosure documents then the sanctions that the arbitral tribunal can impose must be ascertained from the applicable rules or the relevant procedural law. A number of arbitration rules and national laws allow for the arbitral tribunal to correct errors within the award. Most of arbitration legislation and arbitration rules permit the arbitral tribunal to grant orders for interim measure of protection. Article 17(1) of the Revised UNCITRAL Model Law of 2006 states: Unless otherwise agreed by the parties, the arbitral tribunal may, at the request of a party, grant interim measures. Interim measures of protection usually take such forms as (1) conservatory measures intended to prevent irreparable damage and maintain the status quo; (2) conservatory measures intended to preserve evidence or assets. Orders for interim measures by the arbitral tribunal are not self-enforcing. However, the arbitral tribunal must have the powers necessary to make interim measures effective. The Article 17 B of the Revised UNCITRAL Model Law of 2006 provides applications for preliminary orders and conditions for granting preliminary orders. And the Article 17 H provides recognition of enforcement of interim measures. In conclusion, the revised articles with regard to interim measures of the UNCITRAL Model Law of 2006 would contribute significantly to the security of the effectiveness of interim measures in international commercial arbitration. Therefore, Korean Arbitration Law and Arbitration Rules would be desirable to admit such revised articles with regard interim measures.

Objective: To measure Irish opinion on a range of assisted human reproduction (AHR) treatments. Methods: A nationally representative sample of Irish adults (n=1,003) were anonymously sampled by telephone survey. Results: Most participants (77%) agreed that any fertility services offered internationally should also be available in Ireland, although only a small minority of the general Irish population had personal familiarity with AHR or infertility. This sample finds substantial agreement (63%) that the Government of Ireland should introduce legislation covering AHR. The range of support for gamete donation in Ireland ranged from 53% to 83%, depending on how donor privacy and disclosure policies are presented. For example, donation where the donor agrees to be contacted by the child born following donation, and anonymous donation where donor privacy is completely protected by law were supported by 68% and 66%, respectively. The least popular (53%) donor gamete treatment type appeared to be donation where the donor consents to be involved in the future life of any child born as a result of donor fertility treatment. Respondents in social class ABC1 (58%), age 18 to 24 (62%), age 25 to 34 (60%), or without children (61%) were more likely to favour this donor treatment policy in our sample. Conclusion: This is the first nationwide assessment of Irish public opinion on the advanced reproductive technologies since 2005. Access to a wide range of AHR treatment was supported by all subgroups studied. Public opinion concerning specific types of AHR treatment varied, yet general support for the need for national AHR legislation was reported by 63% of this national sample. Contemporary views on AHR remain largely consistent with the Commission for Assisted Human Reproduction recommendations from 2005, although further research is needed to clarify exactly how popular opinion on these issues has changed. It appears that legislation allowing for the full range of donation options (and not mandating disclosure of donor identity at a stipulated age) would better align with current Irish public opinion.
