The number of PET/CT tests for diagnosing and treating tumors are increasing every year, and thus it is considered necessary to compare PET/CT images among medical institutions or among different PET/CT systems within the same medical institution. We present to get the variation of standardized uptake values (SUV) among PET/CT systems, to derive an SUV calibration table that enables quantitative comparison of PET/CT systems, and to test the usefulness of the calibration table through comparing patient's SUV with the SUV calibration table. The correlation coefficients that inter-compared the calibration constants of normal patients and the calibration constants of the mean standardized uptake value with the calibration constants of the standardized uptake value of phantom are 0.88938 (P<0.0001). © 2010 Elsevier Ltd.

Pediculus humanus capitis is an ectoparasite, which causes scalp pruritus particularly among children. A total of 15,373 children including 8,018 boys and 7,355 girls from 26 primary schools and 15 kindergartens attached to the primary schools and a total of 33 children from an orphanage were examined for head lice infestation (HLI). The overall prevalence of HLI in this study was 4.1% including 3.7% of the urban areas and 4.7% of the rural areas. Head lice were found more frequently in girls than in boys with prevalence of 6.5% and 1.9%, respectively. The infestation rate by school grade was 3.2%, 4.7%, 4.2%, 5.0%, 4.9%, 3.8%, and 2.1% for kindergarten, first, second, third, fourth, fifth, and sixth grades, respectively. The infestation rate of the children in an orphanage was 66.7%. The prevalence of HLI has decreased especially in the rural areas. However, HLI is a still health problem of kindergarteners and primary schoolchildren in Korea. © 2010 Springer-Verlag.

This study examines the impact of franchisor social responsibility (FSR) and franchisor image on franchisees. Based on prior research, the study hypothesizes that FSR and franchisor image influence qualities of the relationship with the franchisees (e.g., franchisee trust, franchisee satisfaction). The model was tested on the data collected from food service franchisees in South Korea. The study finds that FSR and franchisor image are critical for building franchisees' trust in the franchisor, which affects franchisees' satisfaction and their long-term orientation. We offer several implications related to the findings. © 2015 Published by Elsevier Ltd.

Akt is a well-established protein that regulates cell growth, survival and anti-apoptotic mechanisms. In this study, we demonstrated that hydrogen peroxide (H 2O 2)-induced oxidative stress regulates the activity of the anti-apoptotic protein Akt via the ubiquitin-proteasome degradation system. H 2O 2 induced cytotoxicity in PC12 cells and decreased the cellular protein and phosphorylation levels of Akt in concentration- and exposure time-dependent manner. This downregulation was blocked by the proteasome inhibitor MG132 and the Akt-specific inhibitor LY294002. In addition, an in vivo ubiquitination assay revealed that the degradation of Akt was mediated by the ubiquitin-mediated proteasome pathway and further demonstrated that this ubiquitination was dependent on the phosphorylation status of Akt. Furthermore, the exogenously overexpressed active form of Akt, but not its inactive form, induced resistance to H 2O 2-mediated cell death. These results suggested that H 2O 2-induced cytotoxicity was mediated by active Akt degradation.

South Korea's health care non-governmental organizations (NGOs) have played a crucial role in South-North relations, for a formal intergovernmental relationship is difficult to establish and also easily breaks down. Humanitarian assistance by NGOs in the health care sector is an area that receives wide support from South Korean society for its urgency and for its appeal to humanity. This humanitarian assistance started in the late 1990's and continued to grow until the late 2000's. This assistance continued throughout the tension between the two administrations that resulted in a radical decrease in overall assistance from South Korea to North Korea. However, concerns remain about the transparency and efficiency of NGO activities. In this article, the NGOs and their major activities are delineated, and South Korean legislation is examined. A current act, the Law on the Development of South and North Korean Relations serves as a basis for governmental regulation and support of NGO's. Humanitarian assistance in the healthcare area is directly related to the health of the North Korean people, and it should not be influenced by political changes. Long-term planning and close discussions between NGOs, their North Korean counterparts, and the South Korean government are needed. NGOs need to overcome their shortcomings such as a lack of expertise and shortage of financial support. For this, NGOs must improve their administration transparency and professionalism. © Korean Medical Association.

The suitability of requirements that are developed and changed is a key factor to make a success of project. The key elements of requirement suitability are the objectives and constraints which are decided by scope. To ensure that requirements have suitability, our study proposes the techniques for measuring requirement suitability considering objectives, constraints and requirements. To calculate requirement suitability points, which are quantities calculated by these techniques, we develop indicators and metrics based on relationship among objectives, constraints and requirements, and propose expressions to quantify our indicators using MCDM (Multi Criteria Decision Making) techniques. An interpretation and usage of our techniques are described by statistical analysis. © 2012 Springer-Verlag.

This study examined the adaptation accuracy of acrylic denture base processed using fluid-resin (PERform), injection-moldings (SRIvocap, Success, Mak Press), and two compression-molding techniques. The adaptation accuracy was measured primarily by the posterior border gaps at the mid-palatal area using a microscope and subsequently by weighing of the weight of the impression material between the denture base and master cast using hand-mixed and automixed silicone. The correlation between the data measured using these two test methods was examined. The PERform and Mak Press produced significantly smaller maximum palatal gap dimensions than the other groups (p<0.05). Mak Press also showed a significantly smaller weight of automixed silicone material than the other groups (p<0.05), while SR-Ivocap and Success showed similar adaptation accuracy to the compressionmolding denture. The correlationship between the magnitude of the posterior border gap and the weight of the silicone impression materials was affected by either the material or mixing variables.

We recently observed that lipoteichoic acid (LTA) isolated from Lactobacillus plantarum inhibited endotoxin-me-diated inflammation of the immune cells and septic shock in a mouse model. Here, we examined the inhibitory role of L. plantarum LTA (pLTA) on the inflammatory responses of intestinal epithelial cells (IEC). The human colon cell line, HT-29, increased interleukin (IL)-8 expression in response to recombinant human tumor necrosis factor (TNF)-alpha, but not in response to bacterial ligands and interferon (IFN)-gamma. TNF-α also increased the production of in-ducible nitric oxide synthase (iNOS), nitric oxide (NO), and intercellular adhesion molecule 1 (ICAM-1) through activation of p38 mitogen-activated protein kinase (MAPK) from HT-29 cells. However, the inflammatory response of HT-29 on TNF-α stimulation was significantly inhibited by pLTA treatment. This pLTA-mediated inhibition accompanied the inhibition of nuclear factor (NF)-kappa B and MAPKs. Our data suggest that pLTA regulates cytokine-mediated immune responses and may be a good candidate for maintaining intestinal homeostasis against excessive inflammation. © 2012 KSMCB.

The aim of the present study was to measure various mechanical properties of acrylic denture base resins, including fexural modulus, fexural strength, fracture toughness, Barcol and Vickers hardness and their related properties, and to investigate correlations between different mechanical properties. Resin specimens were prepared according to manufacturers' recommended instructions. The mechanical properties were measured under specified standards. Data from the mechanical tests were examined using correlation tests. In general, the mean results for mechanical properties of each specimen group were differently ranked depending on the tested mechanical property. The fexural modulus value showed strong or reasonable positive correlation with those of proportional limit, fexural strength, and surface hardness. In contrast, fracture toughness revealed strong negative correlations with the fexural parameters and hardness values. Results of correlation tests for the different parameters can be used for estimation of mechanical performance of acrylic denture bases in clinical situation and for quality control purposes.

High fruit and vegetable consumption is associated with a lower risk of breast cancer. The incidence of breast cancer is continuously increasing in Korea, but only a few studies on nutrition intervention in breast cancer patients has been reported. The aim of this study was to investigate whether an 8-week nutrition intervention based on dietary counseling can promote fruit and vegetable consumption, increase serum antioxidant nutrient levels, and improve quality of life in Korean breast cancer patients. Sixty-one breast cancer patients received either standard care (n = 31) or nutrition counseling (n = 30). The standard care group was given brochures recommending phytochemical rich diet. The intervention group was provided with two nutrition counseling sessions and one cooking class session, thereby encouraged subjects to eat at least 10 or more servings of fruits and vegetables per day. After 8-week intervention, waist circumference in the intervention group was significantly decreased (p < 0.001) even though no difference was reported for body mass index. Energy intake (p = 0.007), fiber (p < 0.001), and antioxidant nutrient (vitamin A, C, E, and -carotene, p < 0.001, respectively) intakes were significantly increased. Serum antioxidant level was also increased significantly, i.e., vitamin A (p = 0.048); vitamin E (p = 0.004). Total vegetable intake (excluding kimchi intake) in the intervention group was increased from 425 g to 761 g (p < 0.001), fruit consumption was also increased from 232 g to 334 g (p < 0.001), while standard care group did not show any significant change. Our study showed that nutrition counseling and providing cooking tips helped to encourage the patient to consume and maintain more fruit and vegetable intakes.
