The purpose of this study was to make and ascertain a decision making process on the base of patient-oriented utilitarianism in the treatment of patients of chronic adult periodontitis. Fifty subjects were chosen in Yonsei Dental hospital and the other fifty were chosen in Severance dental hospital according to the selection criteria. Fifty four patients agreed in this study. NS group(N=32) was treated with scaling and root planing without any surgical intervention, the other S group(N=22) done with flap operation. During the active treatment and healing time, all patients of both groups were educated about the importance of oral hygiene and controlled every visit to the hospital. When periodontal treatment needed according to the diagnostic results, some patients were subjected to professional tooth cleaning and scaling once every 3 months according to an individually designed oral hygienic protocol. Probing depth was recorded on baseline and 18 months after treatments. A questionnaire composed of 6 kinds(hygienic easiness, hypersensitivity, post treatment comfort, complication, functional comfort, compliance) of questions was delivered to each patient to obtain the subjective evaluation regarding the results of therapy. The decision tree for the treatment of adult periodontal disease was made on the result of 2 kinds of periodontal treatment and patient's ubjective evaluation. The optimal path was calculated by using the success rate of the results as the probability and utility according to relative value and the economic value in the insurance system. The success rate to achieve the diagnostic goal of periodontal treatment as the remaining pocket depth less than 3mm and without BOP was
As Korea has reached a free trade agreement with the United States of America, it is required to provide an appropriate procedure to ".kr" domain name disputes based on the principles established in the Uniform Domain Name Dispute Resolution Policy(UDRP). Currently, Internet address Dispute Resolution Committee(IDRC) established under Article 16 of the Act on Internet Address Resources provides the dispute resolution proceedings to resolve ".kr" domain name disputes. While the IDRC's proceeding is similar to the UDRP administrative proceeding in procedural aspects, the Domain Name Dispute Mediation Policy that is established by the IDRC and that applies to disputes involving ".kr" domain names is very different from the UDRP for generic Top Level Domain (gTLD) in substantial aspects. Under the Korea-U.S. Free Trade Agreement(KORUS FTA), it is expected that either the Domain Name Dispute Mediation Policy to be amended to adopt the UDRP or the IDRC to examine the Domain Name Dispute Mediation Policy in order to harmonize it with the principles established in the UDRP. It is a common practice of cybersquatters to warehouse a number of domain names without any active use of these domain names after their registration. The Domain Name Dispute Mediation Policy provides that the complainant may request to transfer or delete the registration of the disputed domain name if the registrant registered, holds or uses the disputed domain name in bad faith. This provision lifts the complainant's burden of proof to show the respondent's bad faith because the complainant is only required to prove one of the three bad faiths which are registration in bad faith, holding in bad faith, or use in bad faith. The aforementioned resolution procedure is different from the UDRP regime which requires the complainant, in compliance with paragraph 4(b) of the UDRP, to prove that the disputed domain name has been registered in bad faith and is being used in bad faith. Therefore, the complainant carries heavy burden of proof under the UDRP. The IDRC should deny the complaint if the respondent has legitimate rights or interests in the domain names. Under the UDRP, the complainant must show that the respondent has no rights or legitimate interests in the disputed domain name. The UDRP sets out three illustrative circumstances, any one of which if proved by the respondent, shall be evidence of the respondent's rights to or legitimate interests in the domain name. As the Domain Name Dispute Mediation Policy provides only a general provision regarding the respondent's legitimate rights or interests, the respondent can be placed in a very week foundation to be protected under the Policy. It is therefore recommended for the IDRC to adopt the three UDRP circumstances to guide how the respondent can demonstrate his/her legitimate rights or interests in the disputed domain name. In accordance with the KORUS FTA, the Korean Government is required to provide online publication to a reliable and accurate database of contact information concerning domain name registrants. Cybersquatters often provide inaccurate contact information or willfully conceal their identity to avoid objection by trademark owners. It may cause unnecessary and unwarranted delay of the administrative proceedings. The respondent may loss the opportunity to assert his/her rights or legitimate interests in the domain name due to inability to submit the response effectively and timely. The respondent could breach a registration agreement with a registrar which requires the registrant to submit and update accurate contact information. The respondent who is reluctant to disclose his/her contact information on the Internet citing for privacy rights and protection. This is however debatable as the respondent may use the proxy registration service provided by the registrar to protect the respondent's privacy.
It is required to expand area of inter-Korean economic cooperation, being limited to non-military field, to military field and then, to positively promote arms control in order to establish foundation for peaceful reunification in Korean peninsula. Reasons why arms control has not been promoted between South and North Korea in the meantime were such original factors as follows; (1) limit of confidence building between the South and the North, (2) functional limit of arms control itself, (3) institutional structural limit between the South and the North, (4) environmental limit at home and abroad. It is necessary to get out from existing frame and to seek a new paradigm in order to overcome above factors and to realize arms control between the South and the North. First, it is required to have prior political dialog at the South-North high-level talks in order to promote arms control and to exercise 'strategic flexibility' during negotiation and promotion process. For this, 'flexible reciprocity' has to be adopted in compliance with situation and conditions. Second, it is necessary to get out from existing principle of 'confidence building in advance and arms reduction later' but to seek the 'simultaneous driving principle of confidence building and arms reduction' as an eclectic approach. Namely, based on reasonable sufficiency, it is required to promote military confidence building and limited arms reduction in parallel, which is a lower level of arms control. Third, as an advisory body of Prime Minister's Office, it is necessary to install an organization exclusively responsible for arms control and to positively handle arms control issue from the standpoint of national policy strategy. If the South-North high-level talks take place, it is necessary to organize and operate 'South-North Joint Arms Control Promotion Board (tentative name)'. Fourth, it is required to exercise more active diplomatic competence in order to create national consensus on necessity of arms control for peaceful reunification and to form more favorable international environment. Especially, it is necessary to think about how to solve nuclear issue of North Korea together in collaboration with international society and how to maintain balance between ROK-US alliance and Sino-Korean cooperation relations.
To promote the aviation safety reporting system that is operated to enhance aviation safety and to utilize related information, it should first be preceded by standards for non-punishment and data protection. It is because the purpose of collection and analysis of aviation safety related data through the aviation safety reporting system is to prevent recurrence of accidents by investigating their causes through collection and analysis of diverse types of information related to aviation safety. Both mandatory and voluntary reporting systems are in operation for aviation safety under the current Aviation Safety Act. It is said that they were introduced to survey causes for accidents and to prevent recurrences. In fact, however, it is hard to expect active implementation of the reporting system for aviation safety unless the reporters are firstly exempted from punishment. Therefore, the system should be improved so that it can satisfy its purpose and the purposes of data collection concerning aviation safety through examination of the purposes of the reporting system. One of the matters that needs to be considered to promote the reporting system should be the scope of aviation safety hindrances presupposed under the current institution. The voluntary aviation safety reporting system differs from the systems of ICAO or the key advanced countries, including the USA and the UK as it limits the target accidents subject to reporting to minor aviation safety hindrances only. That being said, improvements should be made by requiring mandatory reporting of aviation safety hindrances based on their severity while recognizing a greater variety of aviation safety concerns like international standards. Safety actions and sharing of information based on collection and analysis of diverse data related to aviation safety will greatly contribute to enhance aviation safety as the purposes of the reporting system are to explore causes for accidents and to prevent their recurrences. What is most important in this regard is strict data protection and non-punishment principles; compliance with them should be secured. We can hardly expect the successful operation of the system unless the reporter is exempted from punishment and the relevant data is protected as promotion of voluntary reporting is an essential factor for enhancing the safety culture. Otherwise, the current system may induce hiding of relevant facts or data to evade punishment. It is true that the regulation for enhancing safety tends to have limitations or blind spots; nevertheless, it should still be enforced strictly and completely. Technological progresses and mistakes of operators appear in different forms based on individual cases. The consequential damages may amount to a truly severe level. Therefore, we have studied and suggested to the methods of activiation and amendments on the aviation safety reporting system, which is referred for one of the proactive safety management systems. The proposed improvement of the reporting system and introduction of non-punishment for collection of aviation safety data for deploying a preemptive prevention system would serve as the backbone for enhancing aviation safety in Korea.
Background : Patients with lung cancer and their relatives often ask the advice of relative or friends who are doctors on the treatment and prognosis of the disease. Therefore a doctor's opinion may play a role in determining the treatment modality and affect therapeutic compliance of patients. The purpose of this study was to find the opinion of general practitioners on lung cancer treatment. Method : A mail survey for general practitioners in Taegu City and Northern Kyungsang Province was performed. Each individual was sent a written questionnaire in which he or she was asked for ten questions about management and prognosis of lung cancer. Results : Two hundred and twenty eight doctors filled in the questionnaire. Of the respondents, 68% had the experience of being asked about lung cancer by their friends or relatives. About 52% replied that it was better to tell the patient of his or her disease. And about 22% considered it better to follow the relatives' opinion. On the question about choosing the treatment modality, following the doctors' plan was most appropriate in 86.9%, showing that most respondents favored actively recommending doctors. Nonsurgical treatment was preferable in patients over 80 years old with resectable lung cancer and with an increase in age, significant increase was observed in respondents recommending nonsurgical treatment. Most respondents said that they would actively recommend or advise following the doctors' plan about radiotherapy and chemotherapy. But a large percent of the respondents had a negative view on the effect of radiotherapy and chemotherapy. Conclusion : The opinions of general practitioners on the treatment and prognosis of lung cancer was variable. And they did not prefer active treatment for patients with old age or advanced lung cancer.
Purpose: This study was conducted to verify the effects of increases in consuming Korean food in patients who underwent cardiovascular disease (CVD) surgery based on a Korean diet control education program and to investigate the effects of Korean diet control nutrition education on risk factors of CVD, changes in amounts of medication, and nutritional intakes. Methods: The subjects consisted of 15 patients who have undergone CVD surgery within three years and continuously taken cardiovascular drugs. The Korean traditional diet (KTD) emphasizes intake of vegetables and fermented foods to lower saturated fat and cholesterol intake. We applied a KTD education program that included a modified DASH (The dietary approaches to stop hypertension) diet for cardiovascular disease patients. Korean diet control education was then applied to the patients for 12 weeks to evaluate the risk factors of CVD and the state of nutritional intakes. Results: The Korean diet control compliance score increased significantly (p < 0.001) as Korean diet control education was implemented. Additionally, the obesity indexes, waist circumference (WC) (p = 0.002) and waist-to-hip ratio (WHR) decreased significantly (p < 0.001) after subjects received the education. Moreover, the glycemic control index, HbA1c, was significantly decreased (p < 0.05) from
The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times.
