Objective: To investigate whether the expression level of valosin-containing protein (VCP) is correlated with the prognosis of primary orbital mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: VCP expression in 58 samples from primary orbital MALT lymphoma patients was determined by immunohistochemisty using monoclonal antibodies. Correlations between VCP expression level and prognosis were clarified by statistical analysis. Results: It was found that the percentage of VCP positive cells in samples of primary orbital MALT lymphoma ranged from 32% to 95%. The samples were divided into two groups (level 1 and level 2) according to the median value (45%) of the percentage of VCP positive cells. It was found that the expression level of VCP was significantly correlated with recurrence (P=0.003) and tumor size (P=0.008). At the same time, the 5-year disease-free and overall survival rate of patients of level 1 was significantly better than that of level 2 (P=0.001; P=0.032). There was no observed correlation between the expression level of VCP and other clinical features. Conclusion: VCP could be a useful marker for predicting the prognosis of primary orbital MALT lymphoma.

This study investigated whether the increased Basic Pension amount in 2014 affect the level of depression of recipients and whether the effect differs according to three groups by household type(living-alone male, living-alone female, and couple households). Data from two waves of the Korean Longitudinal Study of Ageing(KLoSA) in 2012 (before the introduction of the Basic Pension) and 2016 (after the introduction of the Basic Pension), the elderly aged 65 years or older as of 2012 and the recipients of the basic pension in 2016 (N=2,277) were analyzed. Using the statistical package SPSS 25, mean comparison and multiple regression analyses were implemented. The results confirmed that the level of depression in female elderly living alone and married couples significantly decreased after the introduction of the Basic Pension, while there was no significant change in the level of depression in male elderly living alone. As results of regression analysis in the whole sample, the increased Basic Pension amount had an effect on the depression level of recipients in 2016, the higher the Basic Pension increase, the lower the depression level. Also, the regression analyses among the three groups by household type found that the significant effect of raising the basic pension on depression was reported only in elderly women living alone. Based on the main results of this study, implications were presented.

In relation to differentiated mathematics education, Russia has a longer experience in research and practice than Korea. The mathematics curriculum for 10-11 grades currently in use in Russia is a level-specific curriculum and consists of a basic level and an advanced level. And in Russia mathematics textbooks for 10-11 grades are also textbooks for each level. In this study, we analyzed basic level textbook and advanced level textbook written by the same author group among the textbooks 'Algebra and Introduction of Mathematical Analysis' of the 10th grade in Russia. To analyze the main learning contents and textbook descriptions that were added in advanced level the 'real numbers' and 'complex numbers' sections were studied. The main contents of basic and advanced level textbooks for 'functions', 'trigonometric functions', 'trigonometric equations', 'conversions of trigonometric expressions', and 'derivatives', which are included in both basic and advanced textbooks were compared and analyzed, and the descriptive characteristics of the definitions and theorems presented in the two levels of textbooks were also compared and analyzed. From the results of this study, it is expected that various information on the contents of various level textbooks of mathematics, the differences between textbooks for each level, and strategies for the composition of textbooks for various level can be accumulated.

We investigated the impacts of the diabatic heating location, vertical profile and basic state on the Rossby wave propagation. To examine the dynamical process of individual responses on the regional heat source, a dry version of the linear baroclinic model was used with climatological summertime (JJA) mean basic state and vertical structure of the diabatic heating for 1979-2008. Two sets of diabatic heating were constructed of those positioned in the mid-latitudes (Tibetan Plateau, eastern Mediterranean Sea, and the west-central Asia) and the tropics (the southern India, Bay of Bengal, and western Pacific). It was found that using the principal component analysis, atmospheric response to diabatic heating reaches to the steady state in 19th days in time. The prescribed mid-latitude forcing forms equivalent barotropic Rossby wave propagation along the westerly Asia jets, whereas the tropical forcing generates the Rossby wave train extending from the tropics to mid-latitudes. In relation to the maximum vertical profile, the mid-level forcing reveals a stronger response than the lower-level forcing, which may be caused by more effective Rossby wave response by the upper-level divergent flow. Under the different sub-seasonal mean state, both of the tropical and mid-latitude forcing induce the different sub-seasonal response intensity, due to the different basic-state wind.

Because of low amounts of pension benefit, the Basic Pension of Korea has played a very limited role in reducing the high poverty rates of the elderly. Based on an empirical analysis of the poverty alleviation effect of alternative pension amounts, this paper shows that although the higher basic pension amounts help to reduce the absolute poverty rate of the elderly, it cannot significantly reduce the relative poverty rates. Authors contends that the main objective of the basic pension should be targeted to combat the absolute poverty level. This paper also argues that in order to reduce the relative poverty level of the elderly, the benefit level of National Pension should also be increased.

Objectives : This research identified the frequency and satisfaction level of the observation and performance practice during the clinical practice process conducted by dental hygiene students. With the goal of providing base data required for the development and operation of increasingly effective clinical practice program and for the improvement of the existing clinical practice training. Methods : The subjects in this study were 278 students of a university located in Masan. Survey comprised of 49 questions in 10 clinical practice domains was conducted. Results : 1. As for the observation practice by each grade, there was significant difference in oral radiology, pediatric dentistry, periodontology, oral surgery(p<0.05). As for the performance practice executed for each grade, there was significant difference in the oral radiology, preventive dentistry and oral surgery(p<0.05). As for the satisfaction level for each grade, there was significant difference in basic medical service(p<0.05). 2. As for the observation practice by each clinical practice institution, there was significant difference in oral medicine, oral radiology, preventive dentistry, prosthodontics, pediatric dentistry, orthodontics and oral surgery(p<0.05). As for the performance practice executed by each practice institution, there was significant difference in basic medical service, oral medicine, oral radiology, operative dentistry, prosthodontics, orthodontics, oral surgery(p<0.05). As for the satisfaction level by each practice institution, there was significant difference in the oral radiology, preventive dentistry, operative dentistry, prosthodontics, orthodontics, oral surgery(p<0.05). Conclusions : As for the satisfaction level for the clinical practice, basic medical service is the crimary care clinical practice which is most basic and that is executed the most in a dental clinic. Satisfaction level was the highest in the domains where there were extensive observation and practice frequency. By conducting observation and practice frequency in the clinical practice process by each clinical practice domain in a broad and diverse manner, it would be possible to improve the ability of the clinical practice trainees who improve their clinical work execution capability and satisfaction level on the clinical practice.

We examine 554 state basic districts and 1832 householders in Busan metropolitan city to see whether the physical and walkable characteristics of housing influence apartment housing prices. We use two-level models modeling for a more accurate analysis. Walkable characteristics in level 2 state basic districts potentially explain 77% of the variation in housing values, with the highest impact on crime safety characteristics. Overall, our spatial multi-level analysis based on new state basic districts in Korea explained price variation better than previous studies, which considered each householder. The results provide policy opportunities for planners and citizen groups to pursue strategies that encourage the development of walkable and sustainable neighborhoods.

Myelin basic protein (MBP), a major structural protein of the myelin, is thought to be important for the maintenance of myelin in the central nervous system (CNS). We investigated the effect of maternal folic acid nutritional status on the folate level and the synthesis of MBP in the offspring. In order to test this hypothesis, female Sprague-Dawley rats were fed either folic acid sufficient (8 mg/kg diet) or deficient (0 mg/kg diet) diet from 2 wks prior to the mating throughout the entire pregnancy, lactation and weaning period. We examined plasma folate level by the radioimmunoassay and homocysteine level by HPLC, respectively. The MBP expression was measured by the western blot analysis. The maternal folic acid deficiency decreased plasma folate level with a concomitant increase in plasma homocysteine level in their offspring. The maternal folic acid deficiency decreased hepatic levels of SAM and SAM/SAH ratio with a concomitant increase in hepatic levels of SAH and the MBP expression of spinal cord in their offspring at 7 wks of age. These results suggest that maternal folic acid nutritional status affect plasma folate and homocysteine level in their offspring. Moreover, the maternal folic acid deficiency mi호t inhibit the MBP expression of the spinal cord and disrupt many other vital CNS reactions in their offspring.
