The aim of this paper is to analyze the trend of the research product of Korea and Japan about each other in 20th century. The author analyzed the published year, main period, and author of the research product of history. So she explored the resent state, size, history, and gap of the research product between Korea and Japan. The study about Japan history in Korea began after 1945. However, the study about Korean history in Japan began after 1875. So the study about Japan history in Korea is falling behind Japan for 70 years. As a result, research including the amount of research the number of researchers, the diversity of the minor subject is 1/3 of that conducted by Japanese Scholars.

This study analyzed and compared the number of students activities, contents scope, and organizing system of the three textbooks(A, B, and C) which had been developed and published for the 'Environment'subject in the 7th National Curriculum. The results of this study can be summarized as follows; There were differences in the size, the total number of pages and the quality of print between two groups of 'Environment'textbooks of the 6th and the 7th national curriculum. New textbooks were found bigger than the previous ones by 125%. The total number of pages increased by the average of 16.4%. A and C textbooks were composed of three parts, seven chapters, and 17 sections, whereas B textbook consisted of ten chapters and 23 sections. All of the three textbooks appeared to put an emphasis on the chapters of 'environment protection'and 'environmental problems of the Earth ' A comparative analysis on the number of data included in the three textbooks showed that almost half of data took a form of picture, averaging 48% of the total. A had 297 pictures, and 234 pictures for B, 194 pictures for C, respectively. In terms of the number of students'activities, C was found to include the largest number of activities that is 91, comparing to text A of 85, text B of 78. The number of students'activities in every content is found'environment awaiting protection', tile 'environmental problems of the earth'and'things to be done for the protection of environment'much more than any other parts. It should be noted that this study focused ell only a set of quantitative measures so that teachers are recommended to consider detailed contents that each textbook contains as well as environmental conditions of the school region.

The functional responses of the female Cyrtorhinus lividipennis on brown planthopper (BPH), Nilaparvata lugens, eggs and their predation behavior were investigated at six temperature conditions; 20, 23, 26, 29, 32, and $35^{\circ}C$. C. lividipennis was found to prefer young BPH eggs, especially 3-day-old eggs the most. The functional responses for female C. lividipennis on BPH eggs fitted the Holling's Type-I true predator-prey Rogers' (1972) model at all temperatures tested except $35^{\circ}C$ at which the negative Th value was produced. With the temperature increased up to 32$^{\circ}C$, the instantaneous attacking rate(a) increased from 0.1923 at $20^{\circ}C$ to 0.5085 at $32^{\circ}C$, while the handling time (Th) was gradually decreased as low as 0.0151 at $32^{\circ}C$. C. lividipenis preferred the BPH eggs laid on the upper part of rice stem when the BPH egg density was high, but there was no significant difference in the preference when the egg density was low. The preference was more obvious in high temperature conditions such as above 29$^{\circ}C$.

In the study, CE-QUAL-W2 was used and its examination and correction were conducted targeting 2001 and 2003 when the condition of rainfall was contradicted. Using the proved model in 2003, a scenario was implemented with management of locations for dewatering outlets and actual data for dam management in 1987 when inflow and outflow level were almost same. In case of the scenario which the location of dewatering outlets was 5m higher than usual location, exclusion efficiency for turbid water inflow at the beginning of precipitation was good. In case of the scenario which the location of dewatering outlets was 10m lower than usual location, exclusion efficiency for excluding turbid water remained in a reservoir after the end of precipitation. However, the scenario applying dam management data in 1987, exclusion efficiency was relatively low. In the scenario, power-generating water release spot at EL.57m for first four days after the beginning of precipitation, EL.52m for 5th to 8th and EL.42m from 9th days. An analysis of the scenario reveals that both excessive days exceeded 30 NTU and average turbidity levels were decreased comparing before and after the alteration on outlets. The average turbidity levels were decreased by minimum of 55% to maximum of 70% and 30NTU exceeding days were decreased by 45 days at maximum. Also, since it could exclude most of turbid water in a reservoir before the destatifcation, the risk for turbid water evenly distributed in a reservoir along with turn-over could be decreased as well.

The ${\gamma}$-ray concentration and gross-${\beta}$ activity by age group were measured in the teeth of males and females of the domestic residents. They were divided into 7 age groups from 10s to the age of 70s. The gross-${\beta}$ activity concentration was measured by using the Tennelec XLB measuring instrument filled with P10 gas (argon 90%, methane 10%). The ${\gamma}$-ray was measured through the ${\gamma}$-ray spectroscopic analytical method by using the high purity germanium (HPGe) radiation detector. The range of gross-${\beta}$ activity concentration was measured 0.089 to 0.32 Bq/kg in females and 0.13 to 0.26 Bq/kg in males. From the ${\gamma}$-ray spectroscopic analysis of the teeth, the natural radioactive isotopes of $^{40}K$, $^{208}Tl$, $^{228}Ac$ and $^{234}Th$ were detected and their measured ${\gamma}$-ray activity concentrations were found to be 20.7, 21.9, 3.88 and 5.24 Bq/kg, respectively.

The purpose of this study is to analyze the influence which affects security performance of registered security guards hired by government buildings via job engagement so that basic data can be provided to improve their security performance. To accommodate this study, a survey was conducted from November 26th to December 27th, 2019 through the cooperation of registered security guards working in government buildings in Seoul, Gwacheon, Daejeon, and Sejong. A total of 234 survey sheets were collected and 28 sheets out of them had missing data or incomplete data so a subsequent total of 206 survey sheets were used in this analysis. SPSS 23.0 was applied making use of the collected data for frequency and descriptive statistics analysis, trustworthiness analysis, exploratory factor analysis, and correlation analysis. By applying AMOS 23.0, a means to examine the structural relation between organization, job engagement, and security performance were able to be analyzed. The result of this study is as follows. First, it was found that organizational justice gives a meaningful positive (+) influence on job engagement for registered security guards. Second, it was found that job engagement for registered security guards gives them a meaningful positive(+) influence in their security performance. Third, it was found that organizational justice does not give any meaningful influence on security performance directly. Fourth, organizational justice does not give any meaningful influence on security performance directly but it gives meaningful positive(+) influence on security performance via job engagement as it takes the role of full mediation variable. Based on the results, in order to maximize security performance of registered security guards, this study recommends that government building administrators to try their best to propose to the National Assembly a proposition for Police Assigned for registered security guards Act to be legalized in order to improve the leveling system of registered security guards so that registered security guards can have more job engagement.

This study examined the developmental trajectories of parenting efficacy of mothers of multicultural families and how these trajectories differentiate perceived mothers' career-related behaviors as well as the socio-psychological and academic characteristic of their children in the first grade of high school. The latent class analysis (LCA) and BCH method were applied by using data drawn from the 4th to 10th graders in 2011-2017 from the Multicultural Adolescents Panel Study (MAPS). Results showed that the latent profiles were classified into four groups based on the developmental trajectories of parenting efficacy of mothers of multicultural family: 'high level increasing-decreasing', 'above average increasing-decreasing', 'average unchanged', and 'below average unchanged'. As for demonstrated outcomes, the high parenting efficacy group increased when children were in elementary school but decreased when children were in middle school. At the same time, the low parenting efficacy group did not show much change during these periods. Next, parenting efficacy was a significant determinant of perceived mothers' career-related behaviors and socio-psychological and academic characteristic of their children who attend high school. Based on these results, this study implies a theoretical foundation for developing policies to encourage parenting efficacy of mothers of multicultural families and may result in positive socio-psychological and academic characteristics of their children in high school.
