유일,신정신,소순후 한국중소기업학회 2004 中小企業硏究 Vol.26 No.1

최근 인터넷의 급속한 발전과 전자상거래의 활성화로 웹을 통한 조직간 정보시스템의 구축이 활발히 진행되고 있다. 조직간 정보시스템 구축 가속화 분위기는 조직간에 정보를 공유하고 비용절감을 통해 경쟁우위를 확보하고자 하는 목적으로 이루어지고 있으며, 정보기술의 전략적 활용의 초점이 개별 기업 위주에서 기업간 협력체제 구축과 이를 바탕으로 하는 기업간 전자적 결합으로 옮겨하고 있음을 의미하고 있다. 본 연구는 정보기술의 도입 및 확산에 주고 응용되는 혁신이론을 기초로 조직간 정보시스템이 가지는 다양한 요인을 고려한 확장된 모형을 개발하여, 국내 중소기업의 최고경영층을 대상으로 기업간 정보시스템의 이용에 영향을 미치는 요인들이 무엇인지를 파악하는데 초점을 두었다. 이와 같은 연구 결과를 통해 국내 중소기업이 조직간 정보시스템을 보다 적극적으로 활용하도록 유도하는 지원방향을 제시할 수 있을 것으로 기대된다. Given the importance of adoption of the IOS (Interorganizational System) and the "much-slower-than-anticipated" growth of IOS adoption, especially in small- and medium firms, this study aimed to identify the key determinants of small- and medium-sized firms' IOS usage. Based on prior research on IT/EDI adoption in various organizations, the model that incorporates 9 factors that are hypothesized to have influence on the IOS usage decision was developed and empirically tested on data collected from 114 small- and medium-sized firms' top management. The results show that perceived financial costs are found to be major impediments to usage intention, and perceptions of relative advantage, compatibility, risk are also important determinants of IOS usage intention in small- and medium-sized firms. Implications of these findings are discussed for researchers and practitioners.

Purpose : The aim of this study was to evaluate the effects of oral health care programs in a school-based oral health care center among primary schoolchildren. Methods : School-based oral health care programs included fluoride mouth rinsing, pit and fissure sealing for permanent premolars and molars, fluoride gel application and chewing of xylitol candy. All of the programs were carried out by one dental hygienist among 'D' primary schoolchildren in Daegu city under the supervision of a dentist. Baseline dental examinations were completed and preventive care was implemented for 544 children during one year. All of the children visited a school-based oral health care center every three months for a regular check-up. The final oral examination was conducted from March 15 to April 1, 2004. The data analysis data was made on the basis of SAS 8.01. Mean differences between 2003 and 2004 data were compared by paired t-test. Corresponding p-values were considered significant at values less than 0.05. Results : The DMF rate and DFT index were reduced to 8.0% and 8.4% during one year respectively, but there were no statistically significant differences. The DMF rate was significantly reduced (16.3%) after a one year program of school-based oral health care practice. The DMFT(Decay Missing Filling Tooth) index was also reduced compared to 2003 throughout the entire grade. Conclusion : School-based oral health care programs can reduce the prevalence of dental caries prevalence among schoolchildren during one year. This program also improved the oral health capacity of schoolchildren. It is recommend that the school-based oral health care program should be extended to every primary school in Korea

Purpose: IS prelminary study was designed to assess the clinical variables influencing on the ward atmosphere in psychiatric closed ward and to promote the quality of psychiatric inpatient treatment. Method: 41 psychiatric inpatients were selected in Chung-ju hospital, Konkuk university. Ward Atmosphere Scale(W AS) was used to evaluate patients' perception of ward milieu. WAS score were compared among subgroups with respect to the clinical variables such as duration of admission, frequency of admission, and diagnosis. Results: Significantly, patients who have hospitalized for 1 month to 2 months reported lower score of WAS and patients who have hospitalized for longer than 2 months reported higher score of WAS. The relationship between educated levels and WAS score was not significant. First admitted patients reported significantly lower score of WAS. Bipolar patients reported significantly higher score of WAS and alcohol related patients reported significantly lower score of WAS. Conclusion: The 1st admitted patients, patients with alcohol problem and educated patients were had less satisfied with psychiatric closed ward. Thus, by considering these factors, more specified therapeutic approach and plan should be conducted.

배경: 주물공장 근로자에서 발생한 석면폐증의 작업 관련성을 평가하고 그 증례를 보고하고자 한다. 증례: 30년간 주물공장에서 근무한 환자로 인후통, 기침, 노란 가래가 있어 검사한 결과 결핵이 의심되어 치료 하였으며, 치료 중 석면폐증으로 진단되었다. 작업 관련성 평가를 위해 실시한 폐 조직의 조직학적 검사에서 1 cm^(2)당 3개의 석면소체가 발견되었고, 투과전자현미경으로 분석한 석면 함유량은 23.26x10^(6) fibers/g이었다. 결론: 작업환경조사, 폐 조직의 석면 분석 등을 통해 작업 관련성이 높다고 판단하였다. Background: Foundry workers are known to be exposed to silica and have an increased risk of Silicosis. There are also reports that state these foundry workers were associated with asbestos-related change in the X-ray results of the lungs. This report discusses a case of localized asbestosis developed in a foundry worker who worked in 12 Korean foundries. Case report: A 49-year-o1d man who worked at molding and melting for 30 years, Presented with sore throat, cough and yellow sputum for 1 month. From physical and clinical examination, Pulmonary tuberculosis was highly suspicious; therefore, he was medicated for 6 months. After tuberculosis medication, the radiological finding was reactivation of tuberculosis, and an asbestos body was detected at a trans-bronchial lung biopsy. During an operation, operators found multiple palpable masses and bullae 10calized in the right upper lobe (RUL) and performed right upper lobectomy and right middle lobe wedge resection. Using hematoxylin-eosin stain and iron stain, we could detect asbestos bodies by light microscopy. We analyzed the asbestos fiber burden in dry lung tissue by transmission electron microscopy with energy dispersive X-ray spectrometer (TEM-EDX). The fiber type was chrysotile and the fiber burden was 23.26 x 10^(6) fiber/g dry lung. Discussion: This case study of a foundry worker with localized asbestosis is uncommon in Korea. We found an occupational relationship between the foundry worker and localized asbestosis through various investigative techniques such as measurements taken at his working environment, clinical, radiological and pathological examination of the foundry worker and mineralogical examination of the asbestos fiber.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

<i>Crif1</i> Deficiency Reduces Adipose OXPHOS Capacity and Triggers Inflammation and Insulin Resistance in Mice

Ryu, Min Jeong,Kim, Soung Jung,Kim, Yong Kyung,Choi, Min Jeong,Tadi, Surendar,Lee, Min Hee,Lee, Seong Eun,Chung, Hyo Kyun,Jung, Saet Byel,Kim, Hyun-Jin,Jo, Young Suk,Kim, Koon Soon,Lee, Sang-Hee,Kim, Public Library of Science 2013 PLoS genetics Vol.9 No.3

<▼1><P>Impaired mitochondrial oxidative phosphorylation (OXPHOS) has been proposed as an etiological mechanism underlying insulin resistance. However, the initiating organ of OXPHOS dysfunction during the development of systemic insulin resistance has yet to be identified. To determine whether adipose OXPHOS deficiency plays an etiological role in systemic insulin resistance, the metabolic phenotype of mice with OXPHOS–deficient adipose tissue was examined. Crif1 is a protein required for the intramitochondrial production of mtDNA–encoded OXPHOS subunits; therefore, <I>Crif1</I> haploinsufficient deficiency in mice results in a mild, but specific, failure of OXPHOS capacity <I>in vivo</I>. Although adipose-specific <I>Crif1</I>-haploinsufficient mice showed normal growth and development, they became insulin-resistant. <I>Crif1</I>-silenced adipocytes showed higher expression of chemokines, the expression of which is dependent upon stress kinases and antioxidant. Accordingly, examination of adipose tissue from <I>Crif1</I>-haploinsufficient mice revealed increased secretion of MCP1 and TNFα, as well as marked infiltration by macrophages. These findings indicate that the OXPHOS status of adipose tissue determines its metabolic and inflammatory responses, and may cause systemic inflammation and insulin resistance.</P></▼1><▼2><P><B>Author Summary</B></P><P>Type 2 diabetes is one of the most challenging health problems in the 21<SUP>st</SUP> century. Although insulin resistance is regarded as a fundamental defect that precedes the development of type 2 diabetes, the nature and cause of insulin resistance remain unknown. Adipose tissue is an important organ that determines whole-body energy metabolism, and its dysfunction is a critical element in the development of systemic insulin resistance. Adipose mitochondrial function is suppressed in the insulin-resistant state, and increased adipose mitochondrial biogenesis is associated with the reversal of insulin resistance by a PPARγ agonist. However, despite these important observations, little is known about how mitochondrial respiratory dysfunction in white adipose tissue (WAT) causes insulin resistance. To determine whether adipose deficiency of mitochondrial respiratory capacity plays an etiological role in systemic insulin resistance, the metabolic phenotype of mice with mitochondrial OXPHOS (oxidative phosphorylation)–deficient adipose tissue was examined. Crif1 is a protein required for the translation of mtDNA–encoded OXPHOS subunits. Interestingly, mice haploinsufficient for <I>Crif1</I> in adipose tissue showed reduced OXPHOS capacity and developed marked insulin resistance.</P></▼2>

Ryu, Bog-Mi,Ryu, Seung-Hee,Kim, Mi-Jeong,Lee, Young-Soon,Moon, Gap-Soon The Korean Society of Food Science and Nutrition 2009 Preventive Nutrition and Food Science Vol.14 No.1

To compare antioxidative and antiaging effects between yellow soybean (YS) and Chungkukjang (CK) in vivo system, male Sprague-Dawley rats (n=24) were fed the diets containing YS and CK for 8 weeks, respectively. The YS and CK groups showed the preventive effects on lipid and protein oxidations in liver and plasma. Hepatic SOD and GSH-peroxidase activities were significantly inhibited in CK group. Superoxide anion radicals in cytosol significantly lowered in YS and CK groups compared with control group. In addition, dietary YS and CK effectively inhibited formation of the lipofuscin, the indicator of aging in heart and eye, especially the CK group had a stronger preventive activity in eye. The results of this study showed that YS and CK diet effectively suppressed the superoxide anion radical formation and tissue oxidation.
