The purpose of this study is to compare employee's job satisfaction in the Korean and Foreign brand restaurants, and to suggest some guideline for efficient human resource management. Korean and Foreign brand restaurants are highly showed high vision, pride oneself, and job satisfaction in the restaurant business but payroll is recognized low. Overall job satisfaction is recorded highly in the Korean brand restaurants, but turnover intent is for high foreign brand restaurants. Payroll is the strongest correlates of employee turnover. The guidelines are to continuous evaluation, monitoring about job satisfaction as well as incentive for the high achievement, to establish distinct employee program for reaching high goal & achievement, to provide opportunity self -development and motivation for raising worker's skill, and to utilize regularly video program which discuss complaints between employee and seniors.

The application of the theoretical model to real assembly lines has been one of the biggest challenges for researchers and industrial engineers. There should be some realistic approach to achieve the conflicting objectives on real systems. Therefore, in this paper, a model is developed to synchronize a real system (A discrete event simulation model) with a theoretical model (An optimization model). This synchronization will enable the realistic optimization of systems. A job assignment model of the assembly line is formulated for the evaluation of proposed realistic optimization to achieve multiple conflicting objectives. The objectives, fluctuation in cycle time, throughput, labor cost, energy cost, teamwork and deviation in the skill level of operators have been modeled mathematically. To solve the formulated mathematical model, a multi-objective simulation integrated hybrid genetic algorithm (MO-SHGA) is proposed. In MO-SHGA each individual in each population acts as an input scenario of simulation. Also, it is very difficult to assign weights to the objective function in the traditional multi-objective GA because of pareto fronts. Therefore, we have proposed a probabilistic based linearization and multi-objective to single objective conversion method at population evolution phase. The performance of MO-SHGA is evaluated with the standard multi-objective genetic algorithm (MO-GA) with both deterministic and stochastic data settings. A case study of the goalkeeping gloves assembly line is also presented as a numerical example which is solved using MO-SHGA and MO-GA. The proposed research is useful for the development of synchronized human based assembly lines for real time monitoring, optimization, and control.

Objective: This study was performed to examine differences in the association between straight and curved walking abilities of inpatients in the subacute phase and walking independence level. Design: Cross-sectional study. Methods: Subjects were divided into an independent group and a supervised group (n=10 each) by walking independence level within the ward decided by physical therapists. Inclusion criteria comprised the ability to ambulate independently within the ward, regardless of the use of walking aids. Straight walking abilities (walking velocity, stride length, and cadence) were evaluated using the 5-meter walk test. Curved walking abilities were evaluated using the Figure-of-8 Walk Test (F8W) and the 3-meter zigzag walk test (3ZW). Differences in associations between straight and curved walking abilities of inpatients were examined by calculating correlation coefficients between straight and curved walking abilities. Results: Age, walking velocity, stride length, F8W and 3ZW varied markedly between independent and supervised groups. In the independent group, F8W and 3ZW correlated significantly with walking velocity and cadence (p<0.05). In the supervised group, F8W correlated significantly with walking velocity and stride length (p<0.05), but 3ZW did not correlate significantly with straight walking abilities. Conclusions: The association between straight and curved walking abilities varied between inpatients who could ambulate independently and inpatients requiring supervision for ambulating. These differences may depend on skill on straight and curved walking abilities. There is a possibility that curved walking exercise is necessary for supervised group.

Purpose: Ultrasound imaging is commonly used to measure the pennation angle of human skeletal muscles in vivo. However, manual assessment of the pennation angle using ultrasound images is subjective and time-consuming and requires a high level of examiner skill. The architectural analysis of human skeletal muscles is thus challenging. Automated approaches using image processing techniques are therefore required to estimate the pennation angle in ultrasound images. The purpose of this study was thus to assess the intra-tester and inter-tester reliability and validity of the pennation angle using an automatic measurement program. Methods: Twenty-two healthy young adults (mean age = 22.55 years) with no medical history of neurological or musculoskeletal disorders voluntarily participated in this study. Ultrasound imaging was used to measure the pennation angle of the gastrocnemius muscle at rest. One examiner acquired images from all the participants. The intra-tester and inter-tester reliability were evaluated using the intraclass correlation coefficient (ICC) to estimate reliability. Validity was measured using Pearson's correlation coefficient. Results: The intra-rater reliability was excellent for the automatic pennation angle measuring program and the manual pennation angle assessment method (ICC>0.95). The inter-rater reliability was also excellent for both methods (ICC>0.93). All the correlation coefficients for the automatic pennation angle measuring program and the manual pennation angle assessment method were 0.79, which indicated a significantly positive correlation (p<0.05). Conclusion: Pennation angle measurement using the automatic pennation angle measuring program showed acceptable reliability and validity. This study therefore demonstrated that the automatic measuring program was able to automatically measure the pennation angle of skeletal muscles using ultrasound images, and thus made it easy to investigate skeletal muscle architecture.

With the recent development of hardware performance and artificial intelligence technology, sophisticated fake videos that are difficult to distinguish with the human's eye are increasing. Face synthesis technology using artificial intelligence is called Deepfake, and anyone with a little programming skill and deep learning knowledge can produce sophisticated fake videos using Deepfake. A number of indiscriminate fake videos has been increased significantly, which may lead to problems such as privacy violations, fake news and fraud. Therefore, it is necessary to detect fake video clips that cannot be discriminated by a human eyes. Thus, in this paper, we propose a deep-fake detection model applied with Bidirectional Convolution LSTM and Attention Module. Unlike LSTM, which considers only the forward sequential procedure, the model proposed in this paper uses the reverse order procedure. The Attention Module is used with a Convolutional neural network model to use the characteristics of each frame for extraction. Experiments have shown that the model proposed has 93.5% accuracy and AUC is up to 50% higher than the results of pre-existing studies.

The purpose of this study was to explore the implications of Freire's education theory for secondary school Home Economics Education (HEedu). We conducted a review of books written by Freire and classified the characteristics of his education theory into 9 categories. Based on these categories, we concretely explored the forms in which Freire's education theory could be applied in this area of education through interviews with Home Economics (HE) teachers. We also searched for activities that can be carried out by HEedu agents and the support that can be given by social institutions. The implications of Freire's education theory for HEedu are that education should exhibit love and respect for human beings, be ethically and democratically responsible, enable people to dream as well as hope, support consciousness and praxis by reflection, stimulate epistemological curiosity in learners' lives and experiences, promote subjectivity, autonomy and self-reliance, engage in dialogue to bring about a change in relationships rather than viewing dialogue as a skill, and stimulate political engagement. Freire's education theory therefore has multiple implications for the purpose, mission, and content of education, teaching methods and perspectives, and directions regarding the role of HE teachers. The results are expected to provide practical assistance in developing a persuasive curriculum for HEedu that can help learners restore subjectivity and love for human beings and their society by expanding the horizons of HEedu philosophy from the critical science of Habermas to Freire's education theory.

Civil aircraft must have captain and first officer. In general, the captain fulfills his role and responsibility for preventing danger during aircraft operation, and the first officer is in charge of assisting the captain. Historicclay, as 70% to 80% of aircraft accidents have been caused by pilot human factors, crew resource management (CRM)has been introduced and operated worldwide. On the other hand, safety behavior is a human behavior to protect from danger using knowledge and skills, and the captain and the first officer who perform operations in the aircraft's cockpit are expected to have different levels of safety behavior according to differences in competence, responsibility, and experience. Preceding studies have shown that pilots' safety behavior is influenced by non-technical factors such as CRM Skills rather than technical ability, and this study was conducted to identify differences in CRM competencies between captain and first officer and to verify whether the differences are correlated with safety behavior.

This research examined the design characteristics of Madeleine Vionnet, a female fashion designer who left an enormous legacy and made a great contribution to the high added-value fashion industry. Her techniques can be dividing in to three types: the bias cutting, the design by geometrical methods, and the classical style of ancient Greek clothing. This research also intended to study the design cases in which Vionnet's drapery images are applied to modern fashion, mainly the haute couture works that have appeared at Dior collections since 2000. In terms of the characteristics of Madeleine Vionnet's design, First, she produced the best achievement in dress and ornament history by developing a new technique called bias cutting. Second, her work was groundbreaking because it changed the previously planar approach to the female body into a solid conception by cutting and connecting geometrical pieces in the form of quadrangle, triangle, and a quarter-circle. As a result, her works depicted feminine beauty to the fullest extent through the combination of the human body, excellent materials, and the most sophisticated technology and personal skill. Third, her approach was a classical style tinged with the Greek costume image. With this style, which was born by reinterpreting the key tone of the Greek epoch in a modern way, and transcending and even changing tradition, she created a form of beauty that only she could.
