This paper examine how acceptance of AI robots can be achieved according to occupational groups when the discourse on human labor and occupation changes due to the new industrial revolution is spreading steadily. Previous research on the acceptance of new technologies and products has predicted use behavior through subjective beliefs and values that do not change well over the short term. Therefore, this study compares the beliefs, values, and use intention of AI robots according to occupation. As a result, the subjective belief factor for AI robots was classified into belief in rationality(reason) and belief in benevolence(emotion). The value factors were divided into acceptance value(role performance, communication, social comparison) and avoidance value(risk, complexity). There was a significant difference in the effect of these on the use intention of AI robot by occupation and employment types. This result suggests that there are gaps in the occupation group at the rate of technology acceptance, as opposed to the existing prediction that AI robots will be rapidly expanded by professionals.

Registered security guards carry out police duties as civilian police who are in charge of security service, and so they have a two-fold status: a civilian in terms of a social standing and a policeman in the way that they execute the authority of security. The problem caused by this legal position is that their legal rights and obligation can be unclear in the task-action and working relationship. This paper attempts to study their functions, rights, and legal duties through the interpretation of the related positive law so as to reveal the problems that may spring from this ambiguous status of registered security guards. This endeavor illuminates their legal status specified in the positive law in and around the Act on the police assigned for special guard, observing their functions and the legal duties in the pursuit of their tasks, and ending up pointing out the problems of the positive law. As a result of research work, the most significant problems, even if multifarious, are the avoidance of the state reparation in the responsibility for the illegal behavior in connection with their operation; the unconstitutionality of the disciplinary punishment regulation originated from the entrust with full powers; the imperfection of the rules about the cooperative ties with the police; the possibility of human rights abuse caused by the ban on the labor dispute; the equality problems from the dual pay system; and the inadequacy of the codes about the recruitment qualification and method. This research is intended to help achieve the purpose of the security of national critical facilities through the smooth execute of duties as well as the protection of the guards' rights. Besides, the key focuses posed in this paper are worthy of being developed more accurately through the following researches.

Opisthorchiasis is a major problem in Thailand particularly in northeast region which also has a high incidence of cholangiocarcinomas. Since health modification is needed, this quasi-experimental study aimed to assess the effectiveness of a health education program based on self-efficacy and social support in Tha Tum district, Surin province, Thailand. A total of 70 participants were purposive selected with a history of opisthorchiasis. Participants were divided into experimental and control groups, each with 35 subjects. The experimental group received a health education program composed of: (1) knowledge improvement, lectured with multimedia, demonstration, brochure, and handbook; (2) group discussion about their health beliefs, sharing their ideas and experience; and (3) social support from village health volunteers (VHV), heads of villages (HV), friends, and members of families, and public health officer (PHO). Follow-up was by PHO/VHV/HV, with provision of certificates and flasg for household that did not eat raw fish. Data were collected by predesigned questionnaires after implementation of the program for 3 months. Comparative data was analyzed by paired simple t-test and independent t-test. The results revealed that the experimental group had mean score of knowledge higher more than before the experiment (mean difference=3.1, t=3.915, 95%CI-3.3, -1.8 p-value=0.001), and the control group (mean difference=2.5, t=4.196, 95%CI=1.4, 3.6, p-value=0.001) with statistical significance. The mean scores of practice were higher than before the experiment (mean difference=4.6, t=4.331, 95%CI-5.3, -3.1, p-value=0.001), and control group (mean difference=4.4, t=6.142, 95%CI=4.2, 7.9, p-value=0.001). The mean scores of perceived susceptibility and perceived severity of opisthorchiasis, al well as perceived benefits and perceived barriers to prevention of opisthorchiasis, were also higher than before the experiment and in the control group (p-value <0.001). In conclusion, this was a successful health education program for liver fluke avoidance. Therefore, it may useful for further behavior modification in the other epidemic areas.

Objectives : The object of this study was to make a comparison regarding perceived stressor, perceived stress responses, and coping strategies between patients with gastric ulcer and patients with chronic gastritis. Subject and Methods : Subjects consisted of 40 patients with gastric ulcer and 100 patients with chronic superficial gastritis. Global assessment of recent stress(GARS) scale and perceived stress response inventory(PSRI) were used to measure perception for stressors and stress responses. Coping scale was used to measure coping strategies. Results : Scores of perceived stress related to work or job, changes in relationship on GARS scale were significantly higher in patients with gastric ulcer than those with chronic gastritis. Scores of perceived stress responses related to general somatic symptom, specific somatic symptom, passive-responsive and careless behavior on PSRI were significantly higher in patients with chronic gastritis than those with gastric ulcer. Scores of seeking social support, escape-avoidance on coping scale were significantly higher in patients with gastric ulcer than those with chronic gastritis. Conclusion : The above results suggest that perception for stressors were likely to be higher in patients with gastric ulcer than those with gastritis, whereas perception for stress responses were likely to be higher in the latter than the former. It is also suggested that patients with gastric ulcer were likely to use more dependent and passive coping strategies than patients with gastritis.

Objectives: Operational definition and its validated measure of traditional Korean medicine (TKM) are pivotal for research studies and reliable clinics. There have been ten years of clinical studies on Eum-Yang (Yin-Yang) and Sasang typology using Sasang Personality Questionnaire (SPQ) of integrative biopsychology. The objective of this study was to perform a systematic review on the use of SPQ to provide insights and foundation for its further studies and clinical application. Methods: Clinical studies on SPQ were searched using five domestic and foreign research databases. Attained research articles were then subjected to predefined systematic reviews. Demographic characteristics of participants and research topics of articles were described. Psychological and physical features of SPQ and its subscales were reviewed and compiled to reveal biopsychological characteristics. Results: There were 33 articles with 15,085 participants on Eum-Yang (n=19) and Sasang typology (n=14). The SPQ-total score was in an increasing order of So-Eum, Tae-Eum, and So-Yang. Eum-Yang groups were categorized at a 3:4:3 ratio using %ile score of SPQ-total. The SPQ-total showed a significant positive correlation with Novelty-Seeking and a negative correlation with Harm-Avoidance in psychological perspective, while it was not significantly correlated with Body Mass Index or Ponderal Index in physical perspective. The SPQ-total and subscales explained psychopathological characteristics of stress recognition, negative emotion, problem behavior, and depression. Conclusions: The SPQ was found to be an objective biopsychological measure of TKM for Sasang typology and psychopathology. It would provide foundation for 'Korean Psychology' and multidisciplinary studies.

The purpose of this study was to examine the oral health care and self-rated health status of adults visiting dental clinics in the region of Busan and influential factors for their dental fear from January to May, 2017, in an effort to obtain some information on how to relieve fear. As for dental fear, adults who were in their 30s, who were homemakers and whose monthly income ranged from 4 to 4.99 million won. In regard to fear according to oral health care, dental fear caused by the treatment avoidance factor was stronger among the adults who didn't receive dental checkups and who brushed their teeth in the wrong way. Dental fear that was attributed to the physiological reaction factor and the stimuli-inducing factor was severer among the adults who didn't receive dental checkups and who had no scaling experience. Overall fear was severer among the adults who didn't receive dental checkups and who changed their toothbrushes every four or more months. The factors that affected dental fear were self-rated health status, self-rated oral health status, gender, age, whether to receive dental checkups on a regular basis or not, and oral health education experience. Therefore in order to alleviate dental fear, self-rated health status should be improved, and the kind of system that encourages regular dental checkups and provides oral health education should be prepared.

Least-mean-square(LMS) adaptive filters have proven to be extremely useful in a number of signal processing tasks. However LMS adaptive filter suffer from a slow rate of convergence for a given steady-state mean square error as compared to the behavior of recursive least squares adaptive filter. In this paper an efficient signal interference control technique is introduced to improve the convergence speed of LMS algorithm with tap weighted vectors updating which were controled by reusing data which was abandoned data in the Adaptive transversal filter in the scheme with data recycling buffers. The computer simulation show that the character of convergence and the value of MSE of proposed algorithm are faster and lower than the existing LMS according to increasing the step-size parameter $\mu$ in the experimentally computed. learning curve. Also we find that convergence speed of proposed algorithm is increased by (B+1) time proportional to B which B is the number of recycled data buffer without complexity of computation. Adaptive transversal filter with proposed data recycling buffer algorithm could efficiently reject ISI of channel and increase speed of convergence in avoidance burden of computational complexity in reality when it was experimented having the same condition of LMS algorithm.

A road system with CV(Connected Vehicle)s, which is often referred to as a cooperative intelligent transportation system (C-ITS), provides various road information to drivers using an in-vehicle warning system. Road environments with CVs induce drivers to reduce their speed or change lanes to avoid potential risks downstream. Such avoidance maneuvers can be considered to improve driving behaviors from a traffic safety point of view. Thus, empirically evaluating how a given in-vehicle warning information affects driving behaviors, and monitoring of the correlation between them are essential tasks for traffic operators. To quantitatively evaluate the effect of in-vehicle warning information, this study develops a method to calculate compliance rate of drivers where two groups of speed profile before and after road information is provided are compared. In addition, conventional indexes (e.g., jerk and acceleration noise) to measure comfort of passengers are examined. Empirical tests are conducted by using PVD (Probe Vehicle Data) and DTG (Digital Tacho Graph) data to verify the individual effects of warning information based on C-ITS constructed in Seoul metropolitan area in South Korea. The results in this study shows that drivers tend to decelerate their speed as a response to the in-vehicle warning information. Meanwhile, the in-vehicle warning information helps drivers to improve the safety and comport of passengers.

We tried to develop the school violence prevention program which focuses on the bystanders. In the context of school violence, most students are bystanders. They can either reinforce the violence or stop the violence. We hypothesized that the students who know their own temperament dimensions such as novelty seeking, harm avoidance, and reward dependence (Cloninger, 1994) will show more tendencies to defend victims from school violence when they learned the methods to prevent school violence in accordance to their temperament dimensions. 351 Korean middle school students participated the 4 sessions of school violence prevention program. The students completed the questionnaires to identify their own behavior in school violence situations. In the experimental group(temperament group), students learned the methods to help the victims that suits with their own temperaments. Whereas, the comparison group just attend the class regardless of their temperaments. Both groups showed significant increase in the trend of defending the victims. However, the temperament group showed more tendency to protect/defend the victims than the comparison group when they faced with school violence. These results show that students can learn the methods of defending victims from school violence more easily by knowing their own temperament dimensions, and can be the prepared and the effective defenders.

The purpose of this study was to find out various problem behaviors of children who were not diagnosed with any disability, but instead, engaged in problem behaviors. This study also intended to review the difficulties of children with problem behaviors, their teachers' difficulties and needs, to suggest support for child care and education teachers. This study conducted semi-structured qualitative interviews with eight child care and education teachers. The interviews were transcribed into text and analyzed by contents. The results of this study are as follows. Problem behaviors of children described by teachers were classified into external and internal types. In addition, children with problem behaviors had experienced difficulties in maintaining relationships with their teachers, peers and parents. Many teachers were not successful to provide appropriate support for preschoolers who demonstrated problem behaviors in classrooms or some teachers provided individualized support. Teachers adapted the behavioral and the psychological approaches to problem behaviors of preschoolers. However, teachers reported difficulties with children with problem behavior and brought up the following issues on teaching children with problem behaviors; managing troubled matters happening in the class, difficulty in controlling teacher's emotions on problem behaviors, the lack of time, the integrated child care time without teacher in charge of child, the interruption in activity progress, the lack of a special way to deal with problem behaviors, and difficulty in cooperation with families through parents-teacher counseling sessions. Teachers counseled with parents who had a child with problem behaviors and revealed that parents reacted to problem behaviors in various ways such as embarrassment, acceptance, ignorance, or avoidance. Most teachers received assistance and support for teaching children with problem behaviors, from families, local communities and in-service training. Lastly, teachers with preschoolers with problem behaviors needed the support of experts on managing behavior problems, assistant teaching personnel, education for parents and teachers, respects for teachers, psychological counseling or play therapy from professional service agencies, diagnosis service at child care and education centers which children attended, and support networking with agencies. Teachers also required the family support of medical diagnosis and psychological counseling and financial support from the government.
