The purpose of this study is to examine moderating effect of social relationship on the relationship between academic stress and psychological health among of adolescents. This data used in this study used data was derived from the wave 2-4(2004-2006) of Korean Youth Panel Study (KYPS). The results show that social relationship(parent-child relationship and peer relationship) had a moderating effect on academic stress and psychological health of adolescents. In short, it was verified that in the case of good social relationship, academic stress could actually buffer the effect of psychological health. However, it terms of parent-child relationship, it was not confirmed to have a moderating effect on academic stress and psychological health in the 11th grade. The results from above suggest that schools and related facilities adolescent should consider the program to reinforce social relationship and the timing of the intervention.

Using a two-dimensional numerical model, nuclide transport in the buffer between the canister and adjacent rock in a high-level radioactive waste repository is dealt with. Calculations are made for a typical case with a three-member decay chain, $^{234}$ U longrightarrow $^{230}$ Th longrightarrow $^{226}$ Ra. The solution method used here is based on a physically exact formulation by a control volume method directly integrating the governing equation over each control volume.

This study analyzed the aims, contents, and methods of early education in Sohak(小學) a textbook for childhood education in the choson Dynasty. The analysis was based on the 6th Korean National Kindergarten Curriculum(in process) and the theories of education in Sohak. Sohak consists of Establishing the Education Process(入敎), Clarifying the Cardinal Human Relationships(明倫), Reverencing for the Self(敬身), Examining Antiquity(稽古), Admirable Sayings(嘉言), and Exemplary Deeds(善行). The aim of education in Sohak was to preserve Sheng(性), i.e. human nature inherited from heaven. The contents of education in Sohak was divided into 6 groups: distinction by age and sex, health, basic life habits, private life, family life, and group life. Methods of education in Sohak was the consolidation of knowledge and conduct, education of self control, learning of exploration, learning of constructive models, learning of keep the stages and telling stories of the sayings of the saints.

The purpose of this study was to investigate the effect of perceived parental behavior and children’s coping behaviors with parent-related problems on parent-related stress. The subjects were 234 children composed of 115 3rd-graders and 119 6th-graders elected from three elementary schools in Seoul(121 males and 113 females). Statistical techniques were means, Percentages, Scheffe test, ANOVA and Multiple Regressions. The major findings of this study were as follows : 1) There was a significant difference in parent-related stress with respect to perceived parental behavior and coping behaviors of childrens such as passive, avoidant, and aggressive coping. Perceived parental behavior and aggressive coping behavior showed significant interaction effects. When children perceived parental behavior as being less suppotive and children more aggressively coped with parent-related problems, parent-rotated stress increased in level. 2) Among perceived parental behavior and pasive, avoid, aggressive coping behavior, perceived parental behavior and passive coping behavior were significant predictors of parent-related stress. Perceived parental behavior was much more predictor of parent-related stress than the passive coping behavior.

In order to investigate the effects of api-toxin therapy on depression of immune response, mice were exposed to cold stress $(-20^{\circ}C)$) in 30 minutes twice a day and api-toxin(Bee Venom from Korea and U.S.A) therapy was treated to the Kihae $(CV_6)$ locus of human body every two days with 4 sessions of treatment for 8 days. The mice were sensitized i.v. with $5{\times}10^8$ sheep red blood cells (SRBC) on the 4th day and challenged i.d. with $2{\times}10^9$ SRBC 4 days later. Immune Response for delayed type hypersensitivity (DTH), lympocyte transformation(LTT), hemolysin titer(HL), plaque forming cells (PFC) were measured.

Isotopic analysis using thermal ionization mass spectrometry coupled with scanning electron microscopy (SEM-TIMS) was performed to determine the isotopic ratios of uranium contained in micro-particles in the 6th Nuclear Signatures Interlaboratory Measurement Evaluation Programme (NUSIMEP-6) sample. Elemental analysis by energy dispersive X-ray spectroscopy (EDS) was conducted on uranium-bearing mirco-particles, which were transferred to rhenium filaments for TIMS loading using a micromanipulation system in a SEM. A multi-ion-counter system was utilized to detect the ion signals of the four isotopes of uranium simultaneously. The isotope ratios of uranium corrected by bracketing using a reference material showed excellent agreement with the certified values. The measurement accuracy for $n(^{234}U)/n(^{238}U)$ and (b) $n(^{235}U)/n(^{238}U)$ was 10% and 1%, respectively, which met the requirements for qalification for the NetWork of Analytical Laboratories (NWAL).

In recent years, the studies on the student movement in Republican China have been more accurate. However, some areas still remain uncovered, such as the technology of student movement. In this paper, the author focuses on how students utilize sound tools in their movements, especially in public meetings. During the May 4^th Movement and the 1920s, Chinese students mainly used speaking trumpets without electricity. In the 1930s, electric tools began to appear in student movement for sound propagation. In the student movement of postwar China, students of various political positions could make a use of loudspeaker, wired broadcasting, and megaphone or other equipments. The battle of sound had been part of the Chinese civil war. In general, sound tools had taken an important role in the history of student radicalism.

This paper aims to analyze the recent consolidation of Xi Jinping's power in the context of political reform of the Chinese Communist Party (CCP), and reason out its implications. After Reform and Opening Up, the CCP needed to adapt to the changing society, secure its legitimacy and reinforce its ruling power. Therefore, the CCP has practiced political reform focused on intra-democracy since 16th Party Congress in 2002. Intra-democracy in the CCP's collective leadership consists of two parts: a stable power succession, based on term limits and age limits, and a democratic management system, based on checks and compromises between political factions. Those mechanisms of intra-democracy are still functioning in the Xi Jinping era, which explains that the consolidation of Xi's power is the result of the agreement in the CCP. In other words, it is a short-term change to efficiently deal with challenges the CCP is facing.

Objectives: The objective of this study was to investigate the relationship between smoking history and periodontal disease among the elderly in South Korea. Methods: The study subjects comprised 2,703 elderly people who underwent oral health examination as part of the 7th South Korea National Health and Nutrition Examination Survey (KNHANES; 2016-2018). Data were analyzed using frequency analysis, Rao-Scott chi-square test, t-test, and binary logistic regression analysis. Results: A complex sample logistic regression analysis showed that the odds for periodontal disease development were higher in past smokers (odds ratio [OR]=1.461; 95% CI=1.070-1.994) and current smokers (OR=1.601; 95% CI=1.011-2.536) than in lifetime non-smokers. Conclusions: Smokers must actively participate in smoking cessation programs and interventions starting from middle age.
