<b>Purpose:</b> To evaluate changes in intraocular pressure (IOP) according to position using a portable rebound tonometer. <b>Methods:</b> We measured the IOP values of 20 healthy volunteers (40 eyes) in the sitting, supine, right lateral decubitus and left decubitus positions with a portable rebound tonometer, and then analyzed using the Wilcoxon signed rank test. IOP in sitting position was also measured with a non-contact tonometer and a Goldmann applanation tonometer, and analyzed with Kruskal-Wallis test and Spearman correlation analysis. Agreement among the 3 tonometers was calculated using the Bland-Altman method. <b>Results:</b> The IOP measured with rebound tonometer in the supine position was significantly higher than in the sitting position (<em>p</em> = 0.002). However, there was no significant difference in IOP between the supine and decubitus positions. In the decubitus position, there was no significant difference in IOP between the dependent and non-dependent eyes. IOP measurement using the rebound tonometer showed positive correlation with that of the noncontact and Goldmann applanation tonometers. <b>Conclusions:</b> In normal subjects, IOP measurement obtained with a rebound tonometer in the supine position was significantly higher than in the sitting position, but there was no significant difference in IOP between the supine and decubitus positions. A rebound tonometer may be useful for patients whose intraocular pressure measurement with Goldmann applanation tonometer or non-contact tonometer is impossible. When using a portable rebound tonometer in bed-ridden or pediatric patients, we should pay attention to the interpretation of IOP in the supine position. J Korean Ophthalmol Soc 2014;55(7):1049-1055

본 연구에서는 C2C12 근육 세포의 분화 과정에 있어 IGF-I이 지방산의 수송을 담당하는 지방산 수송체인 FAT/CD36의 mRNA 및 단백질 발현에 미치는 영향에 대해 알아보았다. 그 결과 근육세포의 분화 과정에 있어 FAT/CD36의 단백질과 mRNA 발현이 분화 시간 의존적으로 유의하게 증가하였으며, IGF-I의 처리에 의해서도 유의하게 조절되었음을 알 수 있었다. 이는 IGF-I이 골격근 세포의 성장 및 분화를 촉진하여 근육 관련 유전자들의 발현을 조절하는 기능뿐만 아니라, 골격근의 주요 에너지원으로 사용되는 지방산의 수송을 담당하는 FAT/CD36의 발현에도 영향을 미친다는 것으로 해석할 수 있겠다. 향후 IGF-I이 골격근 세포에서 FAT/CD36의 발현에 영향을 미침으로써 골격근의 지방산 흡수와 산화율을 조절하는지, 그에 따라 지방대사에 어떠한 영향을 미치는지에 대한 연구가 필요할 것이며, 이와 관련된 신호전달 체계 및 기전에 대한 연구도 진행 되어야 할 것이다. Fatty acid transporters are key mediators of skeletal muscle lipid metabolism. Several protein groups have been implicated in cellular long-chain fatty acid uptake or oxidation, including fatty acid transporter proteins (FATPs), the plasma membrane fatty acid-binding protein (FABPpm), and the fatty acid translocase (FAT/CD36). FAT/CD36 is highly expressed in skeletal muscle and known to be regulated by various factors such as exercise and hormones. Insulin-like growth factor-I (IGF-I) is a well-known regulator of skeletal muscle cells. However, it has not been studied whether there is any interaction between IGF-I and FAT/CD36 in skeletal muscle cells. In this study, the effects of IGF-I treatment on FAT/CD36 induction were examined. Differentiated C2C12 cells were treated with 20 ng/ml of IGF-I at different time points. Treatment of C2C12 cells with IGF-I resulted in increased FAT/CD36 mRNA and protein expression. After 24 and 48 hr of IGF-I treatment, FAT/CD36 mRNA increased 89% and 24% respectively. The increase of both proteins returned to the control level after 72 hr of IGF-I treatment, suggesting that the FAT/CD36 gene is regulated pretranslationally by IGF-I in skeletal muscle cells. These results suggest that IGF-I can regulate the expression of FAT/CD36 in skeletal muscle cells. In conclusion, IGF-I induces a rapid transcriptional modification of the FAT/CD36 gene in C2C12 skeletal muscle cells and has modulating effects on fatty acid uptake proteins as well as oxidative proteins.

The objectives of this study were to explore hospital foodservice management and to investigate conditions related to health insurance coverage of inpatient meals. A questionnaire was distributed to the nutrition departments of 44 hospitals in Seoul on July 2009. The average kitchen area was 0.5 m2, and centralized distribution systems were in place. Partition walls from contamination zones, separate work tables to prevent cross-contamination, exclusive areas for preparing tube feeding, and split carts with refrigerated and convection heat settings were largely used in tertiary hospitals. Most dietitians did meal rounds (93.2%) and surveyed for patient satisfaction (86.4%). The major theme of QI (Quality Improvement) was menu management (31.8%). The health insurance fees for meals were ￦4,938.9 for a general diet, ￦5,199.8 for a therapeutic diet, ￦4,067.0 for tube feeding, ￦9,950.0 for sterilized diet, and ￦18,383.4 for diets not covered by health insurance. The prices for general and therapeutic diets were significantly lower in hospitals compared to tertiary or general hospitals (P<0.001). The cost composed of 48.3% food, 44.0% labor and 7.7% overhead for general diets and 47.9%, 44.5% and 7.6% for therapeutic diets. In the case of health insurance coverage for patient meals, the number of items applied to general diets averaged 2.8 out of 4 and for therapeutic diets it averaged 1.9 out of 3. To reform the health insurance coverage system for patient meals, it is urgent that the qualified level of patient meals is presented from a national viewpoint, and monitoring should be performed consistently by developing the evaluation tools.

공공부문 비정규직 노동조합의 임금체계 개편활동과 직무급제에 대한 인식: 무기계약직을 둘러싸고

김혜진 ( Kim Hae-jin ) 한국산업노동학회 2016 산업노동연구 Vol.22 No.3

한국 노동시장의 이중화 해소가 주요한 과제로 대두되고 있고 공공부문에서의 임금개편이 시도되고 있는 시점에서, 본 논문은 공공부문 무기계약직의 임금체계를 이들을 대표하는 노동조합의 관점에서 고찰하였다. 이들 노동조합들의 자료와 노동조합 간부들과의 심층인터뷰를 통해 공공부문에서 진행된 비정규직의 무기계약직 전환과정을 둘러싸고 이들 노동조합들이 임금체계를 어떻게 변화시켜 왔는지, 어떤 임금체계를 지향하고 있는지, 이론적으로 정규직과 비정규직 간의 임금격차를 줄일 수 있다고 제시되는 직무급제에 대해서는 어떤 입장을 견지하는지를 조사하였다. 조사된 대부분의 비정규직 노동조합들은 무기계약직으로의 전환과 함께 조합원들 내에서의 임금격차를 줄이는 방향으로 임금체계를 변화시켜왔는데, 그 지향점은 비교집단인 정규직과 동일하거나 유사한 연공적 임금체계였다. 직무급제에 대해서는 대부분의 공공부문 비정규직 노동조합들이 정확히 이해하지 못하고 있거나 고민하고 있지 않았다. 현재까지 공공부문에서 진행된 비정규직의 정규직화는, 임금수준이나 체계의 측면에서 볼 때 정규직-무기계약직-기타 비정규직이라는 새로운 계층구조를 만들어내고 있다고 보인다. 연구 결과에 비추어 볼 때, 공공부문에서의 임금체계 개편은 비정규직만이 아니고 그 비교대상이 되고 있는 정규직과 함께 이루어져야 형평성과 수용성을 높일 수 있을 것이고, 공공성을 중심으로 노ㆍ정과 시민들의 의견을 모아 합의하는 과정이 중요할 것으로 보인다. Recently the polarization of the labor market has emerged as one of the hottest issues and, accordingly, the government is trying to restructure unlimited-term contract workers` wage structure in the public sector in Korea. This paper investigates wage structures of non-regular workers, unlimited-term contract workers in particular, in the public sector through in-depth interviews with trade union leaders representing non-regular workers. The results are as follows: With temp-to-perm transition, the unions took initiatives to reduce the number of pay grades among their members, so that they could easily adopt the regular workers` wage structure(seniority-based pay system) later. Second, the union leaders don`t fully understand a potential of the job-based pay system in reducing pay gap between regular and non-regular workers. The results also indicate that the temp-to-perm transition in the public sector created multiple strata among public sector workers in terms of pay systems; regular-unlimited term-other non-regular workers. This paper, based on the results, provides a few suggestions about pay system restructuring in the public sector. Restructuring should be applied to regular workers as well as non-regular workers for equity and acceptability. The process of pay system restructuring in the public sector should be focused on public interests and based on consensus among governments, workers and their unions, and citizens.

Hae-Jin Kim(김혜진) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.10

서민들의 삶을 대변하는 전통시장이 오랫동안 소매유통의 중추적 역할을 담당하였으나 생활패턴의 변화와 대형 유통 상권에 능동적으로 대처하지 못해 경쟁력 저하로 침체를 겪고 있다. 최근 전통시장 활성화를 위한 노력이 활발히 전개되고 있는데 사회문화적 기능을 갖고 있는 시장의 경쟁력과 문화를 이용한 활성화 필요성에 대하여 연구하였다. 부산의 남항시장의 사례를 분석하여 하드웨어, 소프트웨어, 휴먼웨어, 공동사업으로 나누어 구체적인 활성화 방안을 제안하였다. The traditional markets representing the lives of ordinary people have been pivotal in retail markets for a long time, but they suffer from deterioration due to the downturns of competitiveness caused by the inactive confrontation with changes of life styles and the large retailers’ marketing territories. Recently the efforts to vitalize the traditional markets are widely developed, and this research will cover the necessity of such activation through the use of market competitiveness and cultural properties which have the social and cultural functionalities. By analyzing the case of Namhang market in Busan, this study suggests the specific activation measures in the aspects of hardware, software, human ware, and a joint venture.

Demand for new computing systems equipped with ultra-high-density memory storage and new computer architecture is rapidly increasing with the tremendous increment of the amount of data produced and/or reproduced. In particular, the requirement for technology development is growing as conventional storage devices face the physical limitations for scaling down and the data bottleneck that the Von Neumann architecture increases. Among the recent emerging memory devices, the conductive bridge random access memory (CBRAM) has superior switching properties and excellent scalability to be adopted as the nextgeneration storage device and as the hardware implementation of the neuromorphic computing system. In this review, the previous papers on the resistive switching mechanism of CBRAM and the precedent CBRAM devices exploiting various materials proposed by many research groups are introduced. The principle of CBRAM is discussed including the operation mechanism, switching materials, and the challenges that need to be solved. A wide selection of materials including metal oxides, Chalcogenides, and other non-oxides have been examined as the electrolyte layer of the CBRAM. Various switching materials, device engineering, and material innovation approaches were introduced, and the research results for solving the problems of CBRAM were reviewed in depth.
