The purpose of this study was to investigate the influences of 5 intrinsic and 5 extrinsic factors on technology teachers' job satisfaction and commitment. The collected data from 108 technology teachers in Gwangju city and Jeolla Nam-do, were analyzed and tested at p<.05 or more by using Multiple Regression through SPSS program. The levels of the teachers' job satisfaction and commitment were respectively M=3.91 and M=3.69 at Likert scale. Among 5 intrinsic and 5 extrinsic factors, other factors except for two factors-work environment and salary were, even if a little, satisfied to the teachers. They were more satisfied with the intrinsic factors than the extrinsic. $R^2$=.515 was found between teachers' job satisfaction and the combination of 10 factors-achievement, work itself, responsibility, opportunity for growth, recognition, job safety, work environment, salary, supervision skill, human relation. $R^2$=.616 was between teachers' commitment with the combination of the factors. The combinations were respectively accountable for 51.5% of the job satisfaction change and for 61.6% of the commitment change. The relative importances of the factors were salary first, achievement second and others not for the job satisfaction, and achievement first, opportunity for growth second and others not for the commitment. The generalization of the above results is limited to improving technology teachers' job satisfaction and commitment at the secondary level in Gwangju city and Jeolla Nam-do.

The purpose of this study is to examine the effects of work value of vocational counselors on organizational commitment and the mediating effect of job satisfaction. For this aim, this study conducted a survey concerning vocational counseling, work value, organizational commitment and job satisfaction targeting 207 vocational counselors in the Jeonbuk region. Analysis results found higher work value of vocational counselors resulted in higher organizational commitment. Second, concerning the relationship between work value and organizational commitment of vocational counselors, job satisfaction showed a significant mediating effect. Furthermore, in accordance with the type of work value, the relationship between organization commitment and both inherent and extrinsic work value had significant mediating effects on job satisfaction. Through this, the study confirmed that when vocational counselors recognize not only the inherent value of work is high, but also the extrinsic value such as benefits that could be obtained socially and economically through job, it is more likely to lead to increased organizational commitment. In particular, it was confirmed that extrinsic value is relatively more influential on job satisfaction and organizational commitment compared with inherent value. This indicates the importance of improving extrinsic value, such as material compensation and job stability, as well as inherent value, such as confidence and pride about the job, for increasing job satisfaction and organizational commitment.

Apoptosis is an important mechanism that regulates cellular populations to maintain homeostasis, and the caspases, a family of cysteine proteases, are key mediators of the apoptosis pathway. Caspase-8 is an initiator caspase of the extrinsic apoptotic pathway, which is initiated by extracellular stimuli. Caspase-8 have two conserved domains, N-terminal tandem death effector domains (DED) and C-terminal two catalytic domain, which are important for this extrinsic apoptosis pathway. In extrinsic apoptosis pathway, death receptors which members of TNF superfamily are activated by binding of death receptor specific ligands from cell outside. After the activated death receptors recruit adaptor protein Fas-associated death domain protein (FADD), death domains (DD) of death receptor and FADD bind to each other and FADD combined with death receptor recruits procaspase-8, a precursor form of caspase-8. The DED of FADD and procaspase-8 bind to one another and FADD-bound procaspase-8 is activated by cleavage of the prodomain. This death receptor-FADD-caspase-8 complex called death inducing signaling complex (DISC). Cellular FLICE-inhibitory proteins (c-FLIPs) regulate caspase-8 activation by acting both anti- and pro-apoptotically, and caspase-8 activation initiates the activation of executioner caspases such as caspase-3. Finally activated executioner caspases complete the apoptosis by acting critically DNA degradation, nuclear condensation, plasma membrane blebbing, and the proteolysis of certain caspase substrates.

Falls are fatal accidents that occur more than 420,000 times a year worldwide. Therefore, to study patients with falls, we found the association between extrinsic injury codes and principal diagnosis S-codes of patients with falls, and developed a prediction model to predict extrinsic injury codes based on the data of principal diagnosis S-codes of patients with falls. In this study, we received two years of data from 2020 and 2021 from Institution A, located in Gangneung City, Gangwon Special Self-Governing Province, and extracted only the data from W00 to W19 of the extrinsic injury codes related to falls, and developed a prediction model using W01, W10, W13, and W18 of the extrinsic injury codes of falls, which had enough principal diagnosis S-codes to develop a prediction model. 80% of the data were categorized as training data and 20% as testing data. The model was developed using MLP (Multi-Layer Perceptron) with 6 variables (gender, age, principal diagnosis S-code, surgery, hospitalization, and alcohol consumption) in the input layer, 2 hidden layers with 64 nodes, and an output layer with 4 nodes for W01, W10, W13, and W18 exogenous damage codes using the softmax activation function. As a result of the training, the first training had an accuracy of 31.2%, but the 30th training had an accuracy of 87.5%, which confirmed the association between the fall extrinsic code and the main diagnosis S code of the fall patient.

This study verified the effect of occupational value, as felt by new employees working in the food service industry, on turnover intent and also the moderating effect of perceived organizational support between occupational value and turnover intent. The analysis drew out the following results. First, the study verified that, among inherent values, only social commitment had a positive(+) direction of influence on turnover intent, and second, among extrinsic values, only face-saving and stability seeking had a positive(+) direction of influence on turnover intent. Third, as a result of verifying the effect of inherent values on turnover intent according to emotional support, the study revealed that turnover intent increased, as the perception of emotional support increased, on condition that the item, value of knowledge seeking, among inherent values, was perceived highly, On the other hand, if the item, relationship-centered, scored highly among inherent values, then the higher the perception of emotional support, the lower the turnover intent. Fourth, as a result of verifying the effect of extrinsic values on turnover intent according to emotional support, the study revealed that turnover intent decreased, as the perception of emotional support increased, on condition that the value of economic priority, among extrinsic values, was perceived highly. On the other hand, if the item, face-saving, scored highly among extrinsic values, then the higher the perception of emotional support, the higher the turnover intent. Fifth, as a result of verifying the differing effect of inherent values according to methodical support, the study revealed that turnover intent increased as the perception of methodical support increased, if the item, knowledge-seeking among inherent values was perceived highly. Sixth, as a result of verifying the differing effect of extrinsic values according to methodical support, the study revealed that turnover intent decreased as the perception of methodical support increased, if the item, economic priority among extrinsic values was perceived highly. On the other hand, if the item, face-saving, among extrinsic values, was perceived highly, the higher the perception of methodical support, the higher the turnover intent.

C- V method is a means to determine the effective channel length for miniaturized MOSFET's. This method achieves L$_{eff}$ by extracting a unique channel length independent extrinsic overlap length($\Delta$L) at a critical gate bias point. In this paper, we conducted an experiment on two different C-V methods. L$_{eff}$ extracted from experiment is compared with L$_{eff}$ simulated from a two-dimensional (2-D) device simulator, and the accuracy of C-V method for L$_{eff}$ extraction is analyzed.

Accidents and incidents caused by poor performance in the maritime industry suggest the need to find ways to improve performance in order to operate effectively and improve safety. The data for this study was collected from maritime students and involves the performance and levels of intrinsic and extrinsic motivation. Various motivational factors were identified and the ways in which these factors relate to performance was analyzed. The importance of considering motivation when recruiting new trainees and workers, and continually looking for ways to increase intrinsic motivation, is stressed throughout this paper. The results suggest that high levels of good quality motivation correlate positively with better performance.

The effects of intrinsic and extrinsic gettering on the formation of microdefects in the wafer and on the electrical performance at near-surfaces of three different oxygen-bearing Czochralski silicon single crystal wafers were investigated by varying the combinations of the pre-heat treatments and the phosphorus diffusion through the back-surface of the wafers. The wafers which had less than 10.9 ppma of oxygen formed no gettering zones irrespective of any pre-heat treatments, while the wafers which had more than 14.1 ppma of oxygen and were treated by Low+High pre-heat treatments generated the gettering zone comprising oxygen precipitates, staking faults, and dislocation loops. The effects of extrinsic gettering by phosphorus diffusion were evident in all samples such that the minority carrier lifetimes were increased and junction leakage currents were decreased. However, the total gettering effects among the different pre-heat treatments did not necessarily correspond to the gettering structure revealed by synchrotron radiation section topograph.

We give criterions for a submanifold to be an extrinsic sphere and to be a totally geodesic submanifold by observing some Frenet curves of order 2 on the submanifold. We also characterize constant isotropic immersions into arbitrary Riemannian manifolds in terms of Frenet curves of proper order 2 on submanifolds. As an application we obtain a characterization of Veronese embeddings of complex projective spaces into complex projective spaces.
