The standardization of weapon system parts is one of the elements of parts management and is an important factor for reducing the cost of acquiring and maintaining a weapon system, enhancing its reliability, improving interoperability, alleviating parts obsolescence problems, improving logistics efficiency, and strengthening the military's combat readiness. This study examined how to manage parts of domestic R&D weapon systems, overseas imports weapon system parts, and various commercial parts from a standardization perspective, and to study parts management methods for standardizing parts in the future. This system was used to achieve systematic part standardization in a military weapon system. To this end, this study investigated what elements are used to standardize weapon system parts. The importance and weight of each element were calculated using the AHP (Analytic Hierarchy Process), one of the decision-making techniques, and the design stage standards using the part selection method were studied. Through this, the selection process of standard parts, which has been made according to the experience and subjective judgment of designers and personnel, was improved to propose a systematic and objective method of standardizing weapons parts.

This study was conducted to determine the levels of job stress, as well as its association with psychosocial factors (type A behavior pattern, locus of control, and self-esteem). Self-administered questionnaires were given to 634 clerical public officers in the C Provincial Office between February 18 and Mar. 10, 2013. As a result, the job stress levels of the subjects was significantly different according to age, sex, educational level, marital status, job position, job career, satisfaction in job life, smoking, alcohol drinking, sleeping time, type A behavior pattern, locus of control, and self-esteem. Regarding the correlation of job stress and psychosocial factors, the level of job demand was negatively correlated with the internal locus of control. The decision latitude was negatively correlated with the type A behavior pattern, internal locus of control and self-esteem. Supervisor support was negatively correlated with the external locus of control. In hierarchial multiple regression analysis, the affecting factors to the job stress selected variables, such as age, subjective health status, job position, overtime work, experience of sick absence, satisfaction in work, sleeping time, leisure time, visiting out-patient department, type A behavior pattern, locus of control, and self-esteem, and the explanatory powers of these factors was 32.1%. In particular, the factors related to the psychosocial factors (type A behavior pattern, locus of control, self-esteem) were strongly related to the job stress, increasing the explanation of factors up to 15.0%.

Pain is subjective and greatly influenced by prior experiences, but it is real. Pain associated with an organic(objective) pathology is more easily explained and treated. However, atypical or unexplainable pain is usually a source of greater confusion and frustration. Pain may be divided into four general diagnostic categories. 1) pain with anatomic features and objective findings 2) pain with anatomic features and without objective findings 3) pain with non-anatomic features associated with stress and somatization 4) pain with non-anatomic features associated with perceived physical injury. There is a well-established relationship between emotional, physical and/or sexual abuse history and development of chronic pain. It has been suggested that the link between somatization and abuse involves a paradoxical pattern of hiding feelings and reality, while seeking acknowledgment of suffering. History of abuse may physiologically and developmentally increase a person's susceptability to pain and organic changes can be associated with psychogenic disease. Patients with chronic pain should be treated with multidisciplinary approaches including exercise, meditation, cognitive therapy, medications, and biofeedback. Cognitive therapy alters patient's cognition and management of pain and alleviates pain, especially associated with stress. Antidepressants are the most commonly used medications and pain control effects have no relation with mood changes. Biofeedback with relaxation training, exercise and meditation may also be effective in pain control.

The purpose of this study was to assess the level of awareness regarding the relationship between systemic diseases and oral health and the importance of education related to this association among dental patients, as well as to identify factors that affect the awareness of the relationship and the perceived need for education. This study was conducted from June 2016 to February 2017. Subjects of this study included outpatients (20-60 years old) from a dental clinic, and only patients who agreed to the survey were included. A total of 110 subjects were included, but the final analysis was based on 92 questionnaires, excluding questionnaires that were inaccurate. Survey questionnaires were completed by self-report and face-to-face interviews with a dental hygienist. The questionnaires covered basic information, awareness of the association between general and oral health, and experience with, and need for education related to, this association. Among the subjects, 48.9% were aware of the association between systemic diseases and oral health. A total of 39.1% of subjects had received education regarding the relationship between systemic diseases and oral health. Subjects who visited dental clinics regularly were 3.94 times (95% confidence intervals [CI]: 1.21-12.84) more likely to be aware of the association between oral health and disease compared with subjects who made only irregular visits to dental clinics. In addition, experience or education was significantly associated with awareness of the relationship between oral health and disease (odds ratio [OR]: 4.64, 95% CI: 1.54-13.93) and the need for education (OR: 3.98, 95% CI: 1.20-13.12). Thus, the dental professionals should provide education on the relationship between oral health and systemic disease in dental clinics to improve patients' awareness and oral health behaviors. These results can be used to strengthen education in the dental clinic.

Body ownership illusion (BOI), which means 'the illusion that a non-bodily object feels like my body', has been actively studied since the Rubber-hand Illusion showed that a person can feel a rubber hand like one's own hand. It has been proven that BOI can be elicited for virtual bodies in virtual reality. Although many studies have been examined the effect of visuomotor (VM) and visuotactile (VT) stimuli, which are mainly used for the elicitation of BOI, there were very limited studies that delivered both stimuli to the whole body at the same time. In this paper, we investigated how each stimulus affects BOI when delivering VM and VT stimulisimultaneously to the virtual avatar, and examined user experience that appears as presence, emotion, and virtual motion sickness. The results showed that BOI was high when VM is synchronous, but there was no significant difference according to VT levels. In the case of presence, it was confirmed that VT affects only when VM is synchronous, and in the case of emotion, both VM and VT affect valence, and in the case of virtual motion sickness, a statistical difference is not found.These results suggest that overall synchrony of VM is important factor in BOI with virtual avatars, but that the matching VT affects subjective experience such as presence when VM is synchronous.

The development of information technology(IT) has brought so-called "online experience" to satisfy our daily needs. The market for online experiences grew more during the COVID-19 pandemic. Therefore, this study attempted to analyze how the features of online experience services affect customer satisfaction by crawling structured and unstructured data from the online experience web site newly launched by Airbnb after COVID-19. As a result of the analysis, it was found that the structured data generated by service users on a C2C online sharing platform had a positive effect on the satisfaction of other users. In addition, unstructured text data such as experience introductions and host introductions generated by service providers turned out to have different subjectivity scores depending on the purpose of its text. It was confirmed that the subjective host introduction and the objective experience introduction affect customer satisfaction positively. The results of this study are to provide various implications to stakeholders of the online sharing economy platform and researchers interested in online experience knowledge management.

In this study, we analyzed science teachers' NOS-PCK in Science Inquiry Experiment lessons. Four science teachers in charge of Science Inquiry Experiment in high schools located in the Seoul metropolitan area participated in the study. NOS Lessons were observed, all of the teaching-learning materials were collected, and semi-structured interviews were conducted. All the collected data were analyzed according to five factors of NOS-PCK. As a result of the study, their understanding and consideration of the curriculum related to NOS were insufficient in some cases. They thought that given inquiry activities or textbook composition was not effective for NOS teaching so that they actively reconstructed the curriculum. In terms of teaching strategies, their lessons were close to explicit approaches. However reflective approaches were generally lacking. They were neglected in evaluating NOS for reasons that views of NOS are individually subjective or that NOS is not an area of cognitive learning. They guessed the state of students by relying on their own experiences rather than based on evaluation results. They recognized a specific aspect of values of NOS learning. And intention to teach NOS played an important role throughout their classes. Based on the above results, we discuss some ways to improve the professionalism of science teachers for NOS teaching.

Objective : The purpose of the research is to investigate Korean occupational therapists' awareness of Evidence-Based Practice(EBP), basis of clinical decision making, barrier factors of EBP execution. Methods : Form December 2009 to March 2010, 500 questionnaires were sent out to clinical occupational therapists and 160 questionnaire which are returned by the therapists were analyzed through descriptive statistics. Results : There are more female respondents than male. More than 90% of them had less than 5 years experience. Most of respondents hadn't experienced education concerning EBP(76%), and the education is not periodically conducted(55%). Moreover, treatment was being tailored based on subjective judgement. On the other hand, the degree of recognition showed that the professionalism of occupational therapists can be improved through EBP(96%), and be helpful to make clinical decision(88%). Most of the therapists answered that guaranteeing enough time to search the basis of treatment(90%) and participating in the education course(92%) is needed to make EBP applicable. This result shows that while the application rate of EBP is low, the recognition rate of EBP is high, which means it is necessary to revitalize EBP education program. Conclusions : In order to provide quality service, education course and instructor training program is needed. We should also make a great effort to offer evidence-based education to occupational therapy students. Furthermore, EBP has to be carried out to improve the professionalism of occupational therapists, and the research about education program and its effect has to be executed.
