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 locus of a camshaft supported on camshaft bearings has been investigated using transient method. Forces applied to camshaft are composed of two components, one is transfer force between cam and tappet, the other is frictional force. These forces have been calculated using lumped mass model and EHL theory. ADI method has been used for numerical analysis of Reynolds equation, and 4th order Runge-Kutta method has been used for transient journal locus analysis. The effects of various load conditions are presented in the form of journal locus. As the result of analysis, it is found that camshaft bearings exist in the hydrodynamic lubrication condition.

The camshaft locus at camshaft beating in a direct acting OHC valve train system has been investigated using the transient method. Forces applied to the camsfiaft are composed of two components, one is the transfer force between the cam and the tappet, the other is the frictional force. These forces have been calculated using the lumped mass model and the elastohydrodynamic lubrication theory. The alternating direction implicit method has been used for the numerical analysis of Reynolds equation, and 4th order Runge-Kutta method has been used for the transient journal locus analysis. The effects of various load conditions are presented in the form of journal locus. As a result of the analysis, it has been found that camshaft bearings were mainly in the hydrodynamic lubrication condition.

This paper gives a review on three illumination issues of face tracking on smart phones: dark scenes, sudden lighting change and backlit effect. First, we propose a fast and robust face tracking method utilizing continuous adaptive mean shift algorithm (CAMSHIFT) and CbCr skin locus. Initially, the skin locus obtained from training video data. After that, a modified CAMSHIFT version based on the skin locus is accordingly provided. Second, we suggest an enhancement method to increase the chance of detecting faces, an important initialization step for face tracking, under dark illumination. The proposed method works comparably with traditional CAMSHIFT or particle filter, and outperforms these methods when dealing with our public video data with the three illumination issues mentioned above.

Locus ordering is the necessary step in constructing genetic map, and the construction of reliable and fine genetic map is one of the most important issue in genetic research area. Locus ordering searches for the best locus order among the possible orders and it amounts to evaluating the maximum likelihood for each order. With only 10 loci, for example, there are 1,814,000 possible orders, and therefore, locus ordering entails a big computational problem. In this paper we suggest a useful algorithm for loci ordering via the Fiedler vector. The suggested algorithm is easy to compute and can handle many loci simultaneously. Furthermore, the required computation time is very short compared to others and the result of locus ordering is very accurate.

Locus control region (LCR) is a cia-acting element which regulates the transcription of genes in developmental stage and/or tissue-specific pattern. Typically, LCR consists of several DNase I hypersensitive sites (HSs), where the binding motifs for transcriptional activators are present. The binding of activators to the HSs recruits chromatin modifying complexes to the LCR, opening chromatin structure and modifying histones covalently through the locus. LCR forms close physical contact with target gene located at a distance by looping away intervening region. In addition, non-coding RNA is transcribed from LCR toward target genes in continuously acetylated active domain. These structural and functional features of LCR suggest that the LCR plays many roles in chromatin activation and transcriptional regulation.

To investigate the interplay between individual and collective self-regulations, the authors propose a dialectic process that describes the changes in the locus of self-regulations between individual self and collective self. The results from three studies display a strong support for the two sets of hypotheses drawn from the proposed process. Our findings demonstrate that consumers can move the locus of self-regulation from individual-self to collective-self when a social identity is activated (preliminary study and study1). Further examination of regulatory swing between individual and collective regulatory orientations revealed group identification as a key variable in determining the locus of self-regulation (study2). While a consumer with a high level of group identification changes her locus of self-regulation from an individual to a collective (a regulatory shift) and evaluated messages and products framed consistent with their group orientation, a consumer with low level of group identification maintains her locus of self-regulation in her personal level of self (a regulatory preservation) and evaluated messages and products framed consistent with their personal regulatory focus.

Purpose: The purpose of this study was to analyzing the relationship between perceived health status, health locus of control, self-esteem, self-efficacy and HPB in patients with multiple myeloma to identify factors influencing health promoting behavior (HPB). Methods: One hundred patients were recruited into the study. The data were collected by personal interviews using questionnaires. Descriptive statistics, Pearson's correlation coefficients and stepwise multiple regression analysis were used with SPSS program to were analyze the data. Results: There were significant relationships between self-esteem (r=.787, p<.001), self-efficacy (r=.681, p<.001), internal health locus of control (r=.557, p<.001), powerful others health locus of control (r=.517, p<.001), chance health locus of control (r=-.251, p=.012), perceived health status (r=.532, p<.001) and HPB. Significant factors in explaining HPB were self-esteem, powerful others health locus of control, self-efficacy and perceived health status and together they accounted for 71% of variance. Conclusion: The study findings indicate that self-esteem, powerful others health locus of control, self-efficacy, and perceived health status were important factors in explaining HPB in patients with multiple myeloma. As self-esteem was an important variable in HPB, health promotion program designed for this population should focus on self-esteem and these other factors to enhance effective health promotion behavior.
