PURPOSE: This study aims to examine the effects of trunk flexion on the kinetic characteristics of the lumbar according to the degree of hamstring flexibility. METHODS: This study has as its subjects 29 young adults and divides them into the group (NSRTG, n=15) with the normal length of hamstrings according to SRT and the group (SSRTG, n=14) tending to have shortened hamstrings. Sit and Reach Test was conducted to evaluate the degree of hamstring flexibility. And to examine the kinetic difference of the lumbar at the trunk flexion, it was compared and analyzed by using the picture archiving and communication system (PACS). RESULTS: SSRTG showed more significant difference than NSRTG in the analysis on the trunk flexion of NSRTG and SSRTG. CONCLUSION: According to the analysis, the shortening of hamstrings is the factor that affects the dynamic stability of the lower lumbar through the reduction of the pelvic anterior tilt at the trunk flexion.

Radioiodine (I-131) Therapy has been known one of the methods treated with hyperthyroidism and thyroid tumor, using a separate ward. This technique has been already used for several decades, and its clinical efficacy proven. Today, Radioiodine takes a form of capsule through continuous development, so, 30 odd domestic hospitals run about 63 separate wards. And, its demands would increase continuously; because of tending upwards the patients had thyroid cancer. However, various kinds of wastes originate from a procedure of radioiodine therapy. Especially, when their radioactivity exceed permissible level (4 Bq/$cm^2$) set by Nuclear laws of the Republic of Korea, it regards as radioactive wastes, then, managed separately from origination to the last disposal.

A recently lot of facilities have been constructed from rapidly development of science and economic growth. Among them, bridges are tending to be large because of geometrical problems of the road. And then the method of satellite surveying is being practical use variously out of present surveying methods. Therefore in this study it takes a measurement of bridge displacement using the RTK GPS Mode instead of the using mechanical measurement system. The observation value was verified by using Total Station to inspect observation value of RTK GPS. And then, by using the Delphi of object intending language, developed bridge warning system and applied it. The result of this study was found verification error of 0.2~8.3mm, therefore the measurement of bridge displacement of grand bridge can be applied by using An GPS.

The wall system has been also tending to shift from existing concrete wall to variable lightweight wall according to increasing use of column structure system in apartment construction. Therefore, wall needs certain amount of strength which also means the standard measurement of resistance against loading of wall attachments is needed. Nevertheless, there currently aren't enough researches of related standards for such measurement. For such reason, the research would be used as baseline data to development for test methods of load resistance about attachments on the lightweight wall, that presented improvements in the apparatus and maximum loads for domestic circumstances by researching current tests.

This study was conducted in order to investigate the quality characteristics of MBA wine resulting from treatment with different oak barrel maturation methods. This study focused on the maturation of wine in five different types of barrels, including a stainless-steel maturation barrel, a foreign medium-toasted oak barrel, and domestic light, medium and heavy toasted oak barrels, and looked at the resulting differences in quality characteristics between the wines. All oak barrels used for this study had a capacity of 100 liters. The results of the study revealed that the pH content increased by up to 3.86~3.93% after 9 months, and then decreased after this point. The total anthocyanin content increased up to 152.52~174.95 mg/L during a 6 month maturation period, and thereafter began decreasing in concentration, with overall anthocyanin levels tending to be higher after maturation in foreign oak barrels. Overall, functional elements tended to measure higher after maturation in foreign oak barrels as opposed to maturation in domestic oak barrels. Therefore, these results indicate that it is necessary to improve the production of domestic oak barrels in the future in order to reliably produce wines with higher levels of functional elements.

Background: Tongue cancer is one of the leading sites of cancer in our population. Aim: To evaluate the socio-demographic profiles and stages at diagnosis of oral tongue (OT) and base of tongue (BT) cancers, and identify any possible variations in characteristics. Materials and Methods: A retrospective analysis was conducted on tongue cancer cases, divided into OT and BT, registered at the hospital cancer registry of North-East India during January 2010 to May 2013. Cases were analyzed for age, gender, residential status and different levels of education for patients, the stage at diagnosis and presence of distant metastasis. Results: A total of 1,113 cases of tongue cancers were registered, 846(76.1%) of BT and 267(23.9%) of OT. While 33.9% of BT cancer patients were above 65 years of age, the figure for OT cancers was 18.4%, stages III and IV accounting for 90.8% and 77%, respectively. The relative risk for distant metastasis in OT cancers was 3.3 (95% CI 1.08-10.1, p=0.03). Conclusions: In the subsites of tongue cancers in our population, the majority arose from the base of tongue, these tending to occur in older individuals and presenting at late stage.

Background: Soft tissue sarcomas (STS) represent 1% of all malignant lesions. In this study the authors analyzed the incidence of STS in Vojvodina (the north region of Serbia) in the period from 1985 to 2009. A number of studies conducted worldwide indicate that STS incidence rates are tending to increase. Materials and Methods: On the basis of data from the Cancer Registry of Vojvodina, age standardized STS incidence rates were established as well as their linear trend, with data on histological structure, age, gender and STS distribution at specific locations. Results: The total number of registered patients was 1,308. Average age standardized rate was 1.90/100,000 per year. The investigated period showed a slight increase in the incidence rate (average annual percent increase=0.77%). The most frequent histological type was sarcoma not otherwise specified-NOS (27%), followed by leiomyosarcoma (21%), liposarcoma (14%), rhabdomyosarcoma (11%) and malignant fibrous histiocytoma (9%). The male/female ratio was 0.73:1. Every fifth patient was younger than 39. Conclusions: Comparison among eight international STS epidemiology studies show that the incidence rate range is between 1.4/100,000-5.0/100,000, though our finding is closer to the lower limit. Furthermore, the incidence rate increase was lower than that characteristic for the half of the analyzed studies. A partial explanation for that should be looked for among changes in diagnostic criteria and STS classifications.

The study analyzed the relationship between self-cognition level of information literacy(SCLIL) and library anxiety(LA). SCLIL was 3.72 point, LA was 2.47 point, and these results are similar to previous studies. SCLIL and LA are correlated each other significantly(r=r=-0.493, p<0.05). Higher SCLIL leads to lower LA. Also, the study found the main factors of LA was lack of methods to access information', 'lack of confidence in evaluating the information's relevance.' For those who are going to major in Library and Information Science, it is found that they have less LA and lower SCLIL compared to those who are not willing to major in Library and Information Science, and this shows a tendency to downplay their own abilities, while tending a more positive image of libraries. Based on the results, recommendations were made to use social and psychological standard tests in order to elaborately and diversely reflect individual information user's psychological aspect.

Purpose: This study aimed to evaluate distribution and maximal value of mechanical stresses on the reconstruction plate, bridging mandibular symphysis defect, and to optimize the most appropriate locations of the plate to distribute the stress causing the fracture of the plate. Materials and methods: Four types of reconstruction were constructed by different number and location of the reconstruction plates on the 3 D finite element model (FEM) of a human edentulous mandible; Type I: one plate on the inferior border of the anterior mandible, Type II: one plate on the middle of the anterior mandible, Type III: one plate on the superior border of the anterior mandible, and Type IV: two plates on the inferior and superior border of the anterior mandible. Results: The results showed that the maximal stress of type I (234.29 Mpa) was lower than that of type II (260.91 Mpa) and type III (247.37 Mpa), but higher than that of type IV (186.64 Mpa). We could also observe that the stresses are tending to focus on the inner side and inferior part of the plate which connected proximal segment from the vertical load. Conclusions: On the basis of the findings, it was concluded that using a plate on the inferior border of mandible or two plates on the inferior and superior border of mandible are more favorable to distribute mechanical stresses, which could reduce the fracture of the plate.
