신건권,조철연 경주대학교 2002 論文集 Vol.15 No.-

As we move further into the Knowledge economy, the value of business will depend more and more on intangible rather than tangible assets. But the traditional accounting systems have been interested in measuring the value of tangible assets only, and have given up on the issue of valuing intellectual assets(or intangible assets, intellectual capital). The accounting systems have not been able to explain the difference between the market value and the book values of firms. The major purpose of this study was to review and evaluate some performance measurement models(Balanced Scorecard, Economic Value- Added, Skandia Navigator, Intangible Assets Monitor, KM's Balance Sheet) in the era of knowledge management. Without an appropriate system for evaluation of intellectual assets, firms could not efficiently manage intellectual assets and strategically utilize them. Because intellectual assets(or intangible assets) are critical resources to management, this study would provide theoretical bases to the systematic evaluation and utilization of them and help firms overcome the limitations of traditional accounting system in handling intangible assets.

Background: People with insulin resistance has a higher risk of developing cardiovascular disease. This leads to the importance in diagnosing metabolic syndrome. The incidence of metabolic syndrome has increased significantly in korea because of an increased population of obese people and also the incidence of DM. There have been many studies done on the incidence of metabolic syndrome in the general population. Therefore, the authors have designed this study to identify the incidence of metabolic syndrome in patients with type 2 DM and also the associated characteristics in that population. Methods: The study included 169 adults over the age of 20 (84 males and 85 females) admitted to the endocrinology department of Chosun University between Jan, 1st 2005 and May, 31st 2006. Out of the people diagnosed with type 2 DM people were excluded when any of the physical measurements (height, weight, blood pressure, abdominal circumference) and blood measurements (TG, HDL-cholesterol, fasting blood sugar) were insufficient and when the patient was taking any drugs other than anti-hy-pertensive agents and oral anti-diabetic agents. Obesity and the other risk factors were defined by the Asian-Pacific guideline and 2001 ATP III of NCEP, respectively. Result: The each prevalence according to the metabolic syndrome criteria of the type 2 DM patients showed low HDL cholesterolemia with the highest incidence of 57.4% followed by hypertng1yceridemia(52.0%), obesity(40.9%) and hypertension(33.0%). The each incidence of diagnostic criteria in metabolic syndrome according to sex was different, In males, hypertriglyceridemia was the highest with the incidence of 57.7% followed by low HDL-cho1estero1emia(49.5%), obesity(40.9%) and hypertension (30.0%). In women, the incidence were low HDL-cho1estero1emia(64.8%), hyperthg1yceridemia(47.6%), obesity(45.0%) and hypertension(36.0%), in a descending order. The analysis between the diagnosis of metabolic syndrome in type 2 DM patients and the criteria showed that hyperthglyceridemia (correlative value 0.575) had the highest correlation followed by low HDL-cholesterolemia (correlative value 0.446), obesity (correlative value 0.350) and hypertension (correlative value 0.410). All the correlations were statistically significant with a p-value less than 0.01. Conclusions: Type 2 DM is a important factor of metabolic syndrome based on insulin resistance. The control of blood glucose with prevention and early diagnosis of the other factors related to metabolic syndrome in type 2 DM is important for preventing cardiovascular complications.

인슐린 자가면역 증후군은 항체에 결합되어 있던 인슐린이 혈당정도와 관계없이 유리됨으로써 저혈당이 야기되는 질환으로, 인슐린종 등과 감별을 필요로 하는 질환이다. 저자들은 고인슐린혈증과 인슐린 자가항체가 양성이면서 공복검사상에서 저혈당이 유발되며 경구 포도당 부하 검사에서 저혈당이 유발된 자가면역성 저혈당증을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hypoglycemia is one of the rare causes of hypoglycemia, and characterized by hyperinsulinemia. Insulin autoimmune syndrome is characterized by insulin autoantibody, hyperinsulinemia, and fasting hypoglycemia without previous insulin immunization. Insulin autoimmune syndrome is usually related to autoimmune disease such as Graves' disease and to previous exposure to drugs. This syndrome is a self-limited disorder. The hypoglycemia was treated with prednisolone and the patient recovered from this. Recently we experinenced two cases of insulin autoimmune syndrome that developed symptomatic hypoglycemia during both the fasting and oral glucose tolerance test. Here in, We present those cases with a review of the literature.

Leukocyte Telomere Length is Associated With Serum Vitamin B12 and Homocysteine Levels in Older Adults With the Presence of Systemic Inflammation

( Chol Shin ),( Inkyung Baik ) 한국임상영양학회 2016 Clinical Nutrition Research Vol.5 No.1

Folate, vitamin B12, and homocysteine (HCY) are involved in the metabolism of nucleic acid precursors and it has been hypothesized that they also influence telomere length, a biomarker of aging. However, previous studies have reported inconsistent findings, and data for older adults are limited. Our study aimed to evaluate associations between leukocyte telomere length (LTL) and serum folate, vitamin B12, and HCY levels among adults aged 55 years and over. In a cross-sectional study in 798 men and women aged 55-79 years, serum folate, vitamin B12, and HCY levels were measured using chemiluminescent immunometric assays, and relative LTL was assessed using quantitative real-time polymerase chain reaction. To evaluate associations between LTL and serum folate, vitamin B12, and HCY levels, multiple linear regression models were used. In multiple models adjusted for age, sex, serum high sensitive C-reactive protein (hs-CRP) levels, and other potential confounding factors, we found no association between LTL and serum folate, vitamin B12, and HCY levels. However, we did find a significant inverse association between HCY levels and LTL in participants with serum hs-CRP levels of ≥ 2 mg/L (p < 0.05). Moreover, there was a trend toward an association between HCY and vitamin B12 levels in these individuals (p = 0.08). In those with serum hs-CRP levels of < 2 mg/L, HCY was inversely associated with vitamin B12 levels (p < 0.001) and had no association with LTL. Our findings suggest that increased serum HCY levels, when combined with the presence of systemic inflammation, may play a role in accelerating biological aging.

Synthesis and electroluminescent properties of new conjugated bithiazole-containing polymers.

Shin, Chol-Min,Kim, Myeong-Jong,Park, Jong-Wook,Kim, Sung-Ryong,Min, Byung-Gak,Chung, Min-Chul,Lee, Ji-Hoon American Scientific Publishers 2008 Journal of Nanoscience and Nanotechnology Vol.8 No.10

<P>Three new bithiazole-based conjugated copolymers were synthesized and characterized. The EL device using PNBTV as the emitting layer showed red electroluminescence at 641 nm with a peak luminance of ca. 160 cd/m2 (0.008 cd/A). The red electroluminescence was attributed to the formation of excimers between the polymer chains. An EL device using PNBTV6 as the emitting material, which had two n-hexyl groups introduced to the phenylene in the main chain of PNBTV, showed a reddish orange emission that was blue shifted by approximately 52 nm compared with that observed with PNBTV. This observation was attributed to the significant decrease in interactions between the chains of the polymers due to the two bulky n-hexyl groups. On the other hand, PNBTV6 was found to have superior hole transporting ability compared with its electron transporting ability.</P>

Application of a General Gas Electrode Model to Ni-YSZ Symmetric Cells: Humidity and Current Collector Effects

Shin, Eui-Chol,Ahn, Pyung-An,Seo, Hyun-Ho,Lee, Jong-Sook The Korean Ceramic Society 2016 한국세라믹학회지 Vol.53 No.5

Electrolyte-supported symmetric Ni-YSZ cermet electrodes of ca. $23{\mu}m$ were prepared by screenprinting and the impedance was measured as a function of humidity from 2% to 90% balanced in $H_2$ at a total flow rate of 50 sccm. The Ni felt current collector of 1 mm thickness exhibited a Gerischer-like gas concentration impedance in the low frequency range, which was similarly observed in the cermet-supported solid oxide cells, while the Pt paste collector exhibited only electrochemical polarization. The electrochemical polarization of both samples was modeled by a non-ideal diffusion-reaction transmission line model including CPEs with ${\alpha}$= 0.5. In the case of the Pt paste collector, all the Bisquert parameters exhibited humidity dependence to the -1/2 power, supporting a non-faradaic chemical reaction mechanism at three phase boundaries. Consequently, the surface diffusivity and reaction rate increased linearly with humidity. Less pronounced humidity dependence and somewhat lower utilization length with an Ni felt collector can be attributed to the diffusion-limited gas flow through the collector.
