"Jocheonillgi", one of the articles left by Jo Heon(1544~1592) whose pen name was Jung-bong, is a travelogue which was written in around 1574~1575 when he was dispatched to Ming as a formal envoy(Giljungkwan). The diary-style manuscript was designated as one of the pieces of the National Treasure 1007. Due to the damage of its binding strings, abrasion, fold, stain, insect and damage on the surface, conservation and restoration was needed. In the process of separation, three more binding strings were found, confirming that the travelogue was rebound at least twice in the past. In addition, the page of 'Yeondoillgi', the original title, was bound inside, confirming that the current cover was revised in the past. As the result of the investigation of base fabric, paper mulberry was found to be the cover, inside paper, lining paper, paper strings. The three kinds of binding string including the current ones was defined to be silk.

Shape optimal design of an excavator boom to minimize weight can be formulated as a nonlinear programming problem with an automesh refinement carried out by using the finite element method. The design variables are the radii and the coordinates of the circle to describe the excavator boundary shape. In addition to the displacement and stress constraints, geometric constraints are imposed such that the nodes cannot cross the certain range. The optimum design is obtained by using the PLBA nonlinear programming code. The sensitivity derivatives are calculated using the semi-analytical scheme. Numerical results of an excavator boom show potential for weight reduction of 4.4%(65.6 kgf) when considering the displacement, stress and geometric constraints.

Purpose: The purpose of this study was to investigate factors that influence maturity fears in elementary school girls. Methods: The participants were 118 3rd and 4th grade students from 3 elementary schools in 3 cities in Korea. Data were collected using questionnaires which included measurement scales for the relative variables and demographic data. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, and hierarchial regression analysis with SPSS/WIN 21.0. Results: The significant predictors of maturity fears were weight, father-child communication, frequency of maturity communication with father, and close relation with mother. Conclusion: For effective management of maturity fears in elementary school girls, programs including weight control, functional communication with father and supportive nurturance of mother should be developed.

Purpose: This study was done to build and test a theoretical model that could be used to explain and predict parenting behavior of mothers with preschool children. Methods: The participants were 298 mothers with preschool children. Data were analyzed using the SAS (Statistical Analysis System) and AMOS (Analysis of Moment Structures) programs. Results: Parenting stress showed a direct effect on parenting satisfaction. Parenting efficacy showed a direct effect on parenting behavior. Parenting stress showed an indirect effect on parenting behavior. Parenting efficacy was found to mediate the relationship between parenting stress and parenting behavior. Income and mother's perfectionism had an impact on parenting behavior. Conclusion: The outcomes of this study indicate the necessity of designing intervention programs that emphasize increasing parenting efficacy in order to increase positive parenting behavior.

A graphics system for optimum design(GOD) was developed for the various optimization programs. It is composed of a preprocessor and a postprocessor using the methods of pull-down and pop-up menus. The preprocessor of GOD system helps the designer to make a input file or a subprogram according to a selected optimization program. The postprocessor of the system display the numerical results generated during the iterative numerical analysis processes graphically in the graphic mode. Numerical examples as a mathematical linear problem and a 3-bar truss structure are presented to explain the use of GOD system. The system was programmed in one of the computer programming languages, Borland C.

As the cargo tank size and configuration of Liquefied Natural Gas carriers(LNGC) grows in response to the global increase in demands for LNG and the necessities of its economical transportation, impact loading from sloshing may become one of the most important factors in the structural safety of LNG Cargo Containment Systems(CCS). The objective of this study is to demonstrate the procedure of the structural safety assessment of MARK III membrane type CCS under sloshing impact loading using local zooming analysis technique of LS-DYNA code.

Purpose: This study was conducted to investigate the structural equation modeling of retention intention in nurses. Methods: A total of 210 nurses from three hospitals in B city, South Korea participated in this study. A structural equation model was constructed to verify the fitness of this model. Data were analyzed using SPSS 20.0 and AMOS 21.0 programs. Results: The hypothetical model appeared to fit the data. Three of the selected six hypotheses for the hypothetical model were statistically significant. The retention intention model showed significant direct effects for job crafting and job demands and indirect effects for relation oriented culture, which explained 28% of the variation in nurses' retention intention. Conclusion: We found that nurses' job crafting behavior and job demands had significant influences on retention intention and relation oriented culture which affected by the factors job crafting.

This study is about Cho Heon-yeong's 『Eastern Medicine Series (東洋醫學叢書)』. It consists of 5 clinical books, 『Therapy for People (民衆醫術理療法)』, 『Tuberculosis Eastern Medical Treatment (肺病漢方治療法)』, 『Neurasthenia Treatment (神經衰弱症治療法)』, 『Gastrointestinal Disease Treatment (胃腸病治療法)』 and 『Gynecological Treatment (婦人病治療法)』, which were published between 1935-1941. This series mainly succeeded 『Donguibogam (東醫寶鑑)』, and was influenced by 『Kyeongakjeonseo (景岳全書)』, and 『Hwangjenegyeong (黃帝內經)』. Cho Heon-yeong's medical philosophy appears in two ways. First, he emphasized invigoration in treatment for the people who lacked nutrition and medical care at the time. Second, eclecticism of Korean Medicine and Western medicine is specifically revealed through this series. He aimed for a comprehensive medicine that consists mainly of Korean medicine and includes only a part of Western medicine.

This study, under the title of Daeungbojeon Hall of Bulyeongsa Temple, Uljin and the architectural technique of the architect, aimed to make a comprehensive speculation on Daeungbojeon Hall of Bulyeongsa Temple whose accurate construction year was confirmed in 1725. While existing studies dealt with it separately between construction and Buddhist art history this study attempted to sort out it in one perspective by means of comparison with compatible objects in the area. The results are as follows. 1st, by means of comparison of wall painting of Daeungbojeon Hall of Bulyeongsa Temple and other wall paintings of Gyeongsang-do Province, it was estimated to be created before and after 1725, the founding year of the building. 2nd, the stylobate of Daeungbojeon Hall is the only and unique case that Guibu was supported by the bottom. Such stylobate was estimated to be built in the early period of Goryeo stylobate of PostLintel Construction which was more simplified than that of the traditional unified Silla period considering specific techniques. Lastly, by means of comparison of the architectural technique of Daeungbojeon Hall of Bulyeongsa Temple with other temples in Gyeongsang-do Province, the characteristics of the building were found. In particular, the same architectural technique was confirmed by direct comparison of style with Yeongsanjeon Hall of Tongdosa Temple in 1714 which was constructed by the same architect.
