웹 서비스의 등록, 검색, 조합, 실행을 자동적으로 수행할 수 있도록 웹 서비스에 시맨틱 웹 기술을 적용시킨 것이 시맨틱 웹 서비스 (Semantic Web Services)이다. 시맨틱 웹 서비스는 원하는 서비스를 찾으려는 사용자의 노력을 줄이기 위에 기계가 이해할 수 있는 정보를 서비스에 추가시킴으로써 정확하게 원하는 서비스를 찾을 수 있게 해준다. 수많은 서비스들 중 같은 역할을 하는 서비스들이 있을 수가 있다. 그 중 하나의 서비스만을 선택해야 할 때 서비스 의 기능이 아닌 질적인 측면에서 QoS(Quality of Service)를 고려하면 최선의 서비스를 선택을 하는데 도움을 줄 수 있다. 따라서 시맨틱 웹 서비스의 검색과 조합의 측면에서 매치메이킹(matchmaking)에 대한 연구의 하나로써 QoS의 매칭에 대한 연구를 수행하게 되었다. 기존의 QoS 매칭과 관련된 연구에서 Qos의 유사도를 계산하는 방법은 Qos요소의 값의 특성을 반영하지 않는다는 것과 Qos 유사도의 순위가 높더라도 좋은 서비스라는 것을 의미하지 않는다는 두 가지 문제점을 발견하였다. 따라서 본 논문에서는 기존 연구의 문제점을 해결할 수 있는 방법을 제시하고자 한다. 먼저 기존의 웹 서비스 관련 연구에서 논의된 여러 Qos 모델의 요소들을 결정하였다. 그리고 기존 연구의 두 가지 문제점을 해경하기 위해 각 Qos 요소의 표준편차를 이용한 표준값을 구하여 QoS 요서의 값의 특성을 반영하였다. 또한 매칭 결과 순위가 높은 것이 사용자에게 더 선호되는 좋은 서비스라는 것을 보장하는 매커니즘을 제안하였다.

Objectives: This study was to examine the social value of dental hygienists, their values about the health system and the relationship of all the related variables. Methods: The subjects in this study were 205 dental hygienists who worked in dental clinics and hospitals on Seoul. A survey was conducted from August 12 to October 15, 2010. The questionnaire consisted of nine items about general characteristics, two items about social values and 11 about values of the health system. The items related to social values and values of the health system were prepared by translating the items used in David et al`s study, and the Cronbach alpha coefficient of those items respectively 0.80 and 0.76. Results: The dental hygienists got 3.94 in social values, which was above the average. In terms of values about the health care system, their values of the treatment delivery system(3.92) rated highest, followed by values of patient rights(3.79) and values of institutional restrictions(3.25). Their socal values had a closest positive correlation to their values of the treatment delivery system, and their values of patient rights had a strong positive correlation to those of the treatment delivery system and was positively correlated to those of institutional regulations as well. And there was a positive correlation between their values of the treatment delivery system and institutional regulations(r=.276). Conclusions: The above-mentioned findings illustrated that the social values of the dental hygienists had a positive correlation to their values of the health system. Therefore the kinds of educational programs that help dental hygienists to build their social values and values of the health system should be developed to improve their job efficiency as oral health experts.

현재 시맨틱 웹 서비스 발견에 대한 연구는 OWL-S를 중심으로 LARKS 프로젝트와 METEOR-S 프로젝트에서 활발히 이루어지고 있다. 그러나 이들 프로젝트들은 OWL-S의 발견 요소를 모두 포함하고 있지 않고 발견 알고리즘을 개선할 필요가 있다. 따라서 본 논문에서는 OWL-S의 발견 요소 중 기존 연구에서 고려하지 않은 프로세스 구조 매칭 알고리즘과 METEOR-S 프로젝트의 QoS 매칭에 대한 알고리즘을 개선한 QoS 매칭 알고리즘을 제안한다. 또한 서비스 분류 매칭과 비즈니스 패턴 매칭을 새롭게 정의한다. 마지막으로 사용자의 선호도를 고려한 매칭 통합 알고리즘을 제안한다. OWL-S has a major leadership in the field of Web Service discovery and is being actively studied in LARKS and METEOR-S projects. These researches do not consider all components of OWL-S standards, and it is needed to enhance their discovery algorithms. In this paper, we propose matching algorithms based on process information such as process structure matching, service classification matching and business pattern matching algorithms. We also improve the QoS matching algorithm of METEOR-S project. Finally, we integrate these two kinds of matching algorithms as accommodate users preferences.

Objectives : The aim of the study is to investigate the antimicrobial activity of jaborandi and sorbitol to various oral microbes. Methods : Jaborandi leaves contain pilocarpine. The conditions for extraction were optimized on the basis of substances, temperatures and pHs. Total pilocarpine content after extraction was analyzed by HPLC. The herbal antimicrobial activity of jaborandi and sorbitol were evaluated for oral microbes containing ATCC 25175 S. mutans, ATCC 13419 S. salivarius, ATCC 6249 S. mitis, ATCC 33398 S. equi, ATCC 29213 S. aureus, ATCC 14053 C. albicans. Results : The optimum conditions for highest yielding extraction were pilocarpine content after boiling at 100oC for 1 hour at pH 3. The level of total pilocarpine content was analyzed at 833 mg/kg by HPLC. The most effective antimicrobial activity was obtained by combination of pilocarpine and sorbitol rather than pilocarpine, menthol and sorbitol, respectively. Conclusions : This results supported the preventive oral health care using safe and convenient jaborandi herb.

Graves` disease following subacute thyroiditis is uncommon. Some patients in these cases showed positive for thyroid antibody only transiently in the resolving phase. However, Graves` disease can rarely be caused by the presence of antibodies after subacute thyroiditis, although the pathophysiology of this is unclear. A 40-year-old woman presented with anterior neck pain and swallowing difficulty. Thyroid function testing showed reduced thyroid-stimulating hormone (TSH) and elevated free thyroxine levels. A thyroid scan revealed decreased uptake in the bilateral thyroid gland. The patient was initially diagnosed with subacute thyroiditis and treated with steroids. Five months later, thyroid function testing showed recurrent hyperthyroidism with positive conversion of TSH receptor antibody, indicating Graves` disease. Since then, she needed the long-term methimazole treatment. In summary, we herein report a case of Graves` disease occurring after subacute thyroiditis. (Korean J Med 2015,89:225-228)

This descriptive study was conducted between October 1, and December 31, 1998 in order to provide basic data for understanding the emotional states of patients with systemic lupus erythematosus and their compliance with a medical regimen. Data was collected by using questionnaires administered to 100 lupus inpatients and outpatients at the Kangnam St, Mary's Hospital. Frequencies, percentage, average, standard deviation, t-test, ANOVA. Duncan's multiple range test, Pearson correlation coefficients, and stepwise multiple regression were applied to the data using the SAS program. The results of study are summarized below. The mean compliance score was 91.21. The highest compliance score was found in "risk factor management", followed by "taking medicine", "follow-up care", "daily life management", "stress management", "diet", "activity and rest" in that sequence. The mean depression score was 43.58. 24% for subjects who showed more than mild depression. The compliance score of depressed subjects was significantly lower than that of the subjects without depression. The mean score of anxiety was 44.01. 36% for subjects who had scores lower than 40 points, 37% for those between 41-50 points, and 27% for those with more than 51 points. As for compliance scores according to anxiety levels, the compliance scores for those with anxiety scores of below 40 significantly higher than that of those of the above 51 group. There was a negative correlation between compliance and depression and between compliance and anxiety. In addition, a strong positive relationship was found between depression and anxiety. The major variable affecting compliance was anxiety, accounting for 13.6%. We concluded that when we care for the patients with lupus, we have to consider the outcomes of this study because emotional status affects the lupus patients' compliance. In addition, it is necessary to develop nursing interventions in order to alleviate the lupus patient's depression and anxiety.
