This study focused on the relationship among perceived social support from care teacher(institution staff), internal locus of control, and school adjustment of institutionalized children. This also examined the differences of perceived social support, internal thou of control, and school adjustment by gender and the duration in the institution. Participant were 119 fifth-and sixth-grade elementary school studens(58 boys, 61 girts). Perceived social support from care teacher, internal locus of control, and school adjustment were measured by self-reports of institutionalized children. The data were analyzed, in SPSS Win program, by Cronbach's α, T-test, Pearson Correlations, Simple Regression, Hierarchical Multiple Regression. As expected, results confirm that perceived social support was associated positively with internal locus of control and school adjustment. further, perceived social support also exerts indirect effects on school adjustment, mediated by internal locus of control. However, none of these variables differed by gender and the duration in the institution.

This study examined the mediating effect of internal locus of control in the relationship between family and friend support and acculturative stress of North Korean adolescent refugees. Participants consisted of 101 North Korean adolescent refugees (40 males and 61 females) aged 13 to 24, who live in Seoul, Gyeonggi Province, and Busan. SPSS 25.0 and Mplus 5.12 were used to analyze data. Descriptive statistics and Pearson's correlation coefficients were calculated and structural equation modeling (SEM) examined the mediating effect. The results of this study are as follows. First, a higher level of family support and friend support were associated with a higher level of internal locus of control. A higher level of internal locus of control was associated with a lower level of acculturative stress among North Korean adolescent refugees. Second, the level of internal locus of control mediated the relationship between friend support and acculturative stress. This study is meaningful in that it examines the specific paths affecting acculturative stress of North Korean adolescent by examining family and friend support, which are environmental factors, and internal locus of control, which is internal factor of individuals. The study results suggest that improving friend support as well as increasing the level of internal locus of control for North Korean adolescent refugees can be an effective way to prevent or intervene acculturative stress.

The cryogenic vessel, storing a liquified solutions as LOX and $LN_2$, consists of a external vessel, internal vessel, thermal insulator and internal support. The internal support should be satisfied with mechanical strength not only to support weight of internal tank but also to maintain uniform space between external and internal tank in spite of external mechanical shock. However, excessive structure design of internal supports is able to increase the amount of heat conduction and the rate of vaporization. The thermal insulator, filled with space between a external and internal vessel, reduces the rate of heat transfer and guarantees the standing time of cryogenic vessel. Especially powder type of insulator has low thermal conductivity and reduce the specification of structure design. In order to evaluate the effect of insulator on structure design, the experiment set-up simulated cryogenic vessel was tested in shock environment according to thermal insulator. As a result, the behavior of internal support under external shock was understood and the design criteria was able to be suggested.

The present paper describes an analytic solution procedure for flexural vibration of a rotationally restrained hinged-hinged Timoshenko beam at the supports during an earthquake. Focusing on maximal magnitudes of internal loads such as bending moment and shearing force under wide variations of two parameters, kL/EI and kGAL²/EI, various beams under synchronous and asynchronous support motions are simulated. The simulations under asynchronous support motions show the following facts. The variations of the maximal magnitudes of internal loads of stocky beams due to the variation of kL/EI from zero to infinity show much wider variations than those of slender beams as kGAL²/EI decreases. The maximal magnitudes of internal loads of a beam tend to be governed by their static components as kL/EI increases and kGAL²/EI decreases. When the internal loads are governed by their static components, maximal magnitudes of internal loads of the stocky tend to increase monotonically as the value of kL/EI increases. However, the simulations under synchronous support motions show the static components of the internal loads vanish and the internal loads are governed by dynamic components irrespective of the two parameters.

This paper reviewed the relationship between internal marketing(management support, education, pay system, internal communication, employment security) and food safety climate(prevention, superior attitude, work condition), and the moderating effect of employment type(permanent or temporary employees) in food service company. Based on the responses from 304 responses, the results of hierarchical multiple regression analysis showed that 4 factors(management support, education, internal communication, employment security) effect positively on food safety climate(prevention, superior attitude, work condition). The positive effect of internal communication on superior attitude and work condition appeared to be more positive in permanent employees than in temporary employees. And the results of t-test analysis showed that permanent employees perceived more positively all internal marketing factors(management support, education, pay system, internal communication, employment security) and food safety climate(precaution, superior attitude, work condition) than temporary employees.

Internal stability is an important safety issue for levees, embankments, and other earthen structures. Since a large part of the world's population lives near oceans, lakes and rivers, floods resulting from breaching of dams can lead to devastating disasters with tremendous loss of life and property, especially in densely populated areas. There are some main factors that affect the internal stability of dams, levees and other earthen structures, such as the erodibility of the soil, the water velocity inside the soil mass and the geometry of the earthen structure, etc. Thus, the mechanism of internal erosion and stability of soils is very complicated and it is vital to investigate the assessment methods of internal stability of soils in embankment dams and their foundations. This paper presents an improved support vector machine (SVM) model to predict the internal stability of soils. The grid search algorithm (GSA) is employed to find the optimal parameters of SVM firstly, and then the cross - validation (CV) method is employed to estimate the classification accuracy of the GSA-SVM model. Two examples of internal stability of soils are presented to validate the predictive capability of the proposed GSA-SVM model. In addition to verify the effectiveness of the proposed GSA-SVM model, the predictions from the proposed GSA-SVM model were compared with those from the traditional back propagation neural network (BPNN) model. The results showed that the proposed GSA-SVM model is a feasible and efficient tool for assessing the internal stability of soils with high accuracy.
