Radiation causes various pathophysiological alterations in living animals, and it causes death at high doses by multiple mechanisms, including direct DNA damage and indirect oxidative stress. The search for useful radioprotectors has been an important issue in the field of radiation biology. Ideal radioprotectors should have low toxicity and an extended window of protection. As many synthetic compounds have toxic side effects, the natural products have attracted scientific attention as radioprotectors. Natural products that have been recently shown to be effective with various biological activities were found to have radioprotective effect. The aim of this review is to summary the recent research of the radioprotective effects of natural foods, especially focused on the glycobiological properties of mushrooms.

Objective : Biologic responses to color stimulation was observed and analyzed in relation with Korean medicine diagnostics. Methods : Twelve volunteers participated and completed the questionnaire on Hanyeol or Joseup patterns of Korean medicine diagnostics. Standard deviation of RR intervals (SDNN), an overall indicator of heart rate variability, was measured while wearing partially transparent acetate film glasses of various colors: (1) transparency or black, (2) red, green, or blue, or (3) cyan, or yellow. Results : Different responses to the color environmental stimulation were observed. Yeol pattern score was inversely related with the SDNN value under red color stimulation. Conclusion : This line of observations may serve as a basis of clinical application of color therapy, in particular, in relation with pattern diagnosis of Korean medicine, and may be applied in combination with existing electrodermal meridian measurement systems for better evaluation of Gi (life energy) phenomenon.

This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

The present study was performed to compare the morpho-physiological characteristics of the tetraploid and diploid varieties of Platycodon grandiflorum and to obtain basic data for cultivating a tetraploid variety with high yield and content of functional substances. The plant height of the tetraploid variety (54.0 cm) was slightly higher than that of the diploid variety. The leaf length and width of the tetraploid variety were 10.2 cm and 7.3 cm, respectively. The results obtained from the present study revealed that the form of the leaf changed from lanceolate to ovate, and the chlorophyll content in the tetraploid variety (16.7) was slightly higher than that in the diploid variety. The photosynthetic rate significantly increased (24%) to $13.4{\mu}mol\;CO_2{\cdot}m^{-2}{\cdot}s^{-1}$ in the tetraploid variety from that of the diploid variety. The pollen viability of the tetraploid variety was decreased by approximately 33% with respect to that of the diploid variety, but this did not have a significant adverse effect on seed production. The fresh weight of tetraploid P. grandiflorum was 49.4 g, which was approximately 44% higher than that of the diploid variety.

Haizi, who ended his life with suicide on the railroad at the age of 25, is a poet who implemented his unique poetic world alone without belonging to any of the existing Chinese poetry schools in the 1980s. The process that Haizi reveals self-inside through a poetic work is rather to hide self-inside paradoxically, too. Accordingly, even a work of figuring out the real intention, which is hidden in poetic dictions that he selected, will be meaningful. In this sense, this study tried to inquire into the poetic imagination and self-image that were revealed in poetry focusing on "Spring, Haizi of 10 People", which is a work of having his name as topic, with having been written at the time of suicide, among Haizi's many poetic works. In addition, it figured out Haizi's private conscious world through analyzing the poem titled "Facing the sea with spring blossoms", which was created ahead of death same as "Spring, Haizi of 10 People". Thus, the aim was to look back on significance of his death and to broaden the width of understanding about Haizi's poetry. As for Haizi, the death can be regarded as the completion of 'performance,' which is a kind of Haizi's own final art form. Hence, Haizi's suicide needs to be seen from the perspective dubbed the continuity of creation through this performance, not the discontinuance of creation caused by 'intended death' that the poet himself selected. In the wake of pursuing the poetic world of a gifted poet Haizi, who died early, that this study examined, there will be any poet of Korea who is recalled naturally. One poet will be first recalled Yi Sang, who is a poet and a novelist of having been broadly known. Another poet is overlapped Gi Hyeong-do, who had been active as a poet and a journalist of having been dead after living in the similar period to Haizi. A comparative analysis among works by these Korean and Chinese poets has similarity beyond the temporal space. A research on this is thought to have value of being considered a little more deeply and generally hereafter. Still, this study mentioned only possibility of a comparative research on this.

Despite the development of information and communication technology, which has a great impact on society and culture, there is no platform that provides a systematic classification and state-of-the-art information retrieval system on the traditional culture. Therefore, this paper developed a traditional culture retrieval system capable of convergence services with systematic classification and retrieval based on automatically generate and visualize the 3D timeline. This system provides the function of collecting traditional culture contents, classifying and storing collected traditional culture contents, and automatically generating 3D digital timeline based on stored traditional culture contents. In addition, a system satisfaction questionnaire was developed to evaluate the usability of the system, and 19 students participated in verifying the system. As a result of the experiment, the satisfaction of the system showed that all items were 'satisfied' on average.

Nowadays, a lot of educational TV programs have focused on the program providers' perspective, namely through goods-dominant (G-D) logic. However, the growing development of current technologies such as IPTV with AR and VR has opened opportunities to go beyond a provider-centered perspective and to add the co-creation of value, since value can be created through the interaction between learners and the TV programs themselves. With this in mind, learner-centered TV programs, which are based on service-dominant (S-D) logic, should be offered through educational TV channels. This conceptual paper summarizes, analyzes, and synthesizes the present status of IPTV in education and suggests a new instructional approach for utilizing TV in future education based on value co-creation through learner participation. Three principles (service-dominant logic as an educational service design principle, goal-based scenario for instructional design, IPTV as state-of-the-art technology innovation) are suggested for designing educational IPTV programs.

The objective of this study was to evaluate the flood control capacity of the agricultural reservoir based on state-of-the-art climate change scenario - SSP (Shared Socioeconomic Pathways). 18 agricultural reservoirs were selected as the study sites, and future rainfall data based on SSP scenario provided by CMIP6 (Coupled Model Intercomparison Project 6) was applied to analyze the impact of climate change. The frequency analysis module, the rainfall-runoff module, the reservoir operation module, and their linkage system were built and applied to simulate probable rainfall, maximum inflow, maximum outflow, and maximum water level of the reservoirs. And the maximum values were compared with the design values, such as design flood of reservoirs, design flood of direct downstream, and top of dam elevation, respectively. According to whether or not the maximum values exceed each design value, cases were divided into eight categories; I-O-H, I-O, I-H, I, O-H, O, H, X. Probable rainfall (200-yr frequency, 12-h duration) for observed data (1973~2020) was a maximum of 445.2 mm and increased to 619.1~1,359.7 mm in the future (2011~2100). For the present, 61.1% of the reservoirs corresponded to I-O, which means the reservoirs have sufficient capacity to discharge large inflow; however, there is a risk of overflowing downstream due to excessive outflow. For the future, six reservoirs (Idong, Baekgok, Yedang, Tapjung, Naju, Jangsung) were changed from I-O to I-O-H, which means inflow increases beyond the discharge capacity due to climate change, and there is a risk of collapse due to dam overflow.

This paper describes the processes conducted in the analysis and conservation of suit worn by Yu Rim (1898-1961). The suit consists of a jacket and pants and is a typical Mao-style suit for independence activists; it is notable in that it was made of domestic wool. Inside the jacket, there is a machine embroidery of the name "Danju," a label of synthetic resin which reads "Daegu citizen's tailor's shop," and buttons engraved with "PUSAN SIN-HUNG." According to our textile analysis, the outer layer is composed of worsted wool while the lining is made from acetate. Damage to the garment from malodor and insects has been repaired, and the suit has been restored to its original shape by a conservation treatment that has reinforced the textiles. This conservation case can provide valuable research data on the preservation of modern and contemporary clothing. In addition, this study also attempts to estimate the date of suit worn by Yu Rim's production by comparing it with woolen suits produced around the same time and examining the clues associated with the relics. This is significant since it enhances the value of the cultural assets and provides detailed information on the historical transformation of domestic suits.
