Many studies have recently reported reactivation in hepatitis B surface antigen (HBsAg)-negative subjects with the use of biologic agents such as rituximab. However, occult hepatitis B virus infection itself has little clinical impact. We experienced a case of acute exacerbation caused by occult hepatitis B infection without HBsAg seroconversion. No mutation was found on the major hydrophilic loop of the S protein. The patient recovered from acute exacerbation after antiviral therapy. In conclusion, acute exacerbation can be induced by occult hepatitis B virus infection itself without reactivation. In such a case, antiviral therapy should be considered.

지능형 서비스 로봇 산업은 기계공학 및 전자공학 기술이 유기적으로 연관성을 가지는 시스템 산업이다. 지능형 서비스 로봇 산업은 고부가가치 산업으로 자원이 부족한 국가에서도 육성이 가능한 지식 집약적인 미래형 산업이다. 지능형 서비스 로봇산업은 대기업보다 창의성 있는 중소기업 및 벤처기업의 참여가 많이 이루어지고 있으며, 적용 분야가 다양하고 수요자의 요구도 다양해지고 있다. 지능형 서비스 로봇의 사업화 요인을 수요요인, 환경요인, 기술요인으로 분석하였다. 기술요인은 기술수준, 기술로드맵 등을 분석한 후 성장촉진 요인과 성장저해 요인을 분석하였다. 국내 지능형 서비스 로봇은 주로 청소용 로봇과 애완용 로봇위주로 사업화되고 있으나 향후에는 교육용 로봇, 노인/재활지원 로봇, 가사지원 로봇 등으로 사업화가 진행될 전망이다. An intelligent service robot industry is a system industry that is strongly relevant to both mechanical engineering and electronics technologies. It is also a very knowledge-intensive industry that countries with limited resources would put their efforts for the promotion as a highly value-added industry. Many small and medium sized and venture enterprises participate in this area these days, and application fields and customers' needs expand to a large degree. In this study authors analyzed the commercialization factor of intelligent service robots in terms of demand, environmental and technological factors. Technology levels were characterized and technology roadmap was drawn, for the analysis of the technological factors, followed by the analysis of growth promotion and blocking factor analyses. Current domestic trend in the commercialization of intelligent service robots is limited mainly to cleaning robots and pet robots.

Introduction : The Object of this study is to investigate the reference ranges of total antioxidant status(TAS) according to age and sex in korea. The human body is constantly under attack from free radicals. Free radica1s are highly reactive molecules and once formed, attack cell structures with the body. As a resu1t, free radicals have been implicated in numerous disease. In hea1thy individua1s, the antioxidant system defends tissues against free radica1 attack. Methods and materials : We measured the tota1 antioxidant status of 90 norma1 group, 30 diabetes group and 30 hypercholesterolemia group. (The each group sex ratio : ha1f to ha1ij For each test, age and sex related variations were assessed and reference values were estimated for three different age groups.(below 20, 21-40, above 41) TAS measured by Randox Tota1 Antioxidant reagent and Hitachi 7150. Results : ’fhe reference va1ues according to age were 0.930- 1.332mmolfL in below 20 years of age, 1.007 -1.391mmolfL in 21-40 years of age and 0.995- 1.295mmolfL inabove 41 year of age and showed statistica11y significant difference.(P<0.05) The Reference ranges of tota1 age group, ma1e and fema1e group were 0.991- 1.343mmolfL, 1.038- 1.370mmolfL, and 0.977 -1.285mmolfL respectively. Between the ma1e and fema1e group were statistically signficant difference.(P<0.05) The TAS means of diabetes and hypercholesterolemia were 1.26mmoljL and 1.23mmoljL respectively. TAS values of hypercholerterolemia an normal group were no significant difference whereas diabetes and normal group were significant difference.(P<O.OOl) Conclusions : We established that reference ranges were analyzed age and sex related variations for total antioxidant status. Between experimental groups showed generally significant differences. In the future, correct diagnosis of disease induced free radicals need to measure total antioxidant level and each antioxidants.

In general, the performance of a component degrades as time goes by and failure of a component occurs when the performance degradation reaches a pre-specified level. It is difficult to obtain the failure time distribution data or the necessary number of failure data especially for the metal or machine part. Thus, a design of reliability qualification test based on performance distribution is more effective than failure time distribution. In this study, a performance-based reliability qualification test is developed and a numerical example is provided to illustrate the use of the developed reliability qualification test. This approach could be applied to many kinds of metal or machine part whose magnitude of strength could not be evaluated during at any random points but judgement can be made by only failure of the part. Besides, it is also possible that any parts which have a similar failure characteristics could be applicable to the developed reliability qualification test.

Die vorliegende Korpusstudie untersucht Verbalkomposita in der deutschen Schriftsprache. Neben den morphosyntaktischen Funktionen werden auch semantische Aspekte berucksichtigt. Einen wichtigen Bezugspunkt fur die Analyse bildet “Duden”, das Standardwerk fur die deutsche Rechtschreibung und Orthographie. Alle untersuchten Verbalkomposita, die mit heim-, statt-, teil-, frei- und hochgebildet werden, sind trennbar. Das gilt auch fur 30 von insgesamt 35 Verben, die in Kombination mit voll- erscheinen. Bei der Komposition mit frei- (z. B. “freigeben”) empfiehlt “Duden” zwar die Zusammenschreibung, doch sei das nicht obligatorisch. Bei einigen frei-Komposita treten abhängig von der Schreibweise Bedeutungsveränderungen auf. So erlaubt “freimachen” im Sinne von ‘nicht zur Arbeit gehen’ oder ‘die Kleidung ausziehen’ die Getrenntschreibung, wohingegen die Zusammenschreibung zwingend erforderlich ist, um die Bedeutung ‘einen Brief frankieren’ kommunizieren zu können. Aus der Gegenuberstellung der genannten kompositabildenden Morpheme gehen zahlreiche Bedeutungsuberschneidungen, aber auch -unterschiede hervor, die auf komplexe Weise mit syntaktischen Kategorien wie Transitivität interagieren. Ziel der Studie ist es, eine systematische Beschreibung dieser Zusammenhänge zu leisten.

This study was a qualitative study conducted using a focus interview method to explore the meaning of the experiences of participants who practiced oil pulling for oral health. The data collection period was from October 16, 2023 to November 10, 2023, and the study participants were 12 women interested in oral health. To collect data, three interviews were conducted, each interview lasting 1 hour and additional interviews between 20 and 30 minutes. Using the thematic analysis stage to analyze the interview data, the participants’ subjective experiences regarding the oil pulling experience were ‘oil pulling divided into hobbling experiences for the first time’, ‘changes felt gradually in the mouth’, ‘improved oral immunity’, ‘Oil pulling as an alternative’ was derived into four themes. Oil pulling has been shown to be effective in maintaining oral hygiene and health and if used as an aid to toothbrushing, it can contribute to improving oral immunity. Based on this study, we propose the development of oil products that can support oral health. 본 연구는 구강 건강을 위해 오일풀링을 실천한 참여자들의 경험의 의미를 탐색하기 위해 포커스 인터뷰 방법을 사용하여 진행된 질적 연구이다. 자료수집 기간은 2023년 10월 16일부터 2023년 11월 10일까지이었고, 연구 참여자는 구강 건강에 관심이 있는 12명의 여성이다. 자료수집을 위해 3회의 면담, 1회 면담 시간은 1시간, 추가 면담은 20~30분 사이로 진행되었다. 면담 자료 내용을 분석하기 위해 주제분석 단계를 활용하여 오일풀링 경험에 대한 참여자들의 주관적 경험은 ‘처음 경험하는 호불호로 나뉘는 오일풀링’, ‘서서히 느껴지는 입안의 변화’, ‘향상되는 구강 면역’, ‘양자택일의 오일풀링’으로 4개의 주제로 도출되었다. 오일풀링은 구강 위생과 건강 유지에 효과가 있는 것으로 나타났고 칫솔질의 보조 수단으로 활용한다면 구강 면역의 향상에 기여할 수 있을 것이다. 본 연구를 기반으로 구강 건강을 보조할 수 있는 오일 제품 개발을 제언한다.
