With massive and dense production, the livestock industry is rapidly moving into a large-scale, capital-intensive industry especially in swine, poultry, and ducks. However, livestock epidemics can pose a serious threat to the livestock industry and the lives of the people. The government has established and operates the National Animal Protection and Prevention System (KAHIS) since 2013 in order to control the threat, in accordance with the five stages. The digitalized data and information are excellent in ease of management, but it is also pointed out that it is difficult to take countermeasures through linkage with the data in an emergency situation. Recently, the technology of the fourth industrial revolution such as Internet of Things (IoT), Big Data, Artificial intelligence (AI) has been rapidly implemented to the livestock industry, which makes smart livestock disease control system possible. Therefore, this study investigated the domestic and overseas cases which apply 4th Industrial Revolution technology in the industry, and derived 13 possible candidate tasks in the near future. In order to ascertain the priority of policy formulation, we surveyed the expert groups and examined the priority of each of the five stages of the prevention and the priority of each stage. The results of this study are expected to contribute to the establishment of policies for the advancement of smart livestock disease control research and livestock protection.

This study attempted to identify factors work environment that affect job satisfaction in dental hygienists. This study was conducted between August 29 and September 28, 2017, as part of an in-depth study of the 'Survey on the Working Environment of Clinical Dental Hygienists' of the Korean Dental Hygienists Association. To get the responses, the questionnaire was posted on the website of the Korean Dental Hygienists Association, and of the respondents, 4,663 were selected and analyzed. An independent t-test and one way ANOVA analysis were used to make a comparison of job satisfaction according to the general characteristics, salary, and tasks. Logistic regression analysis was conducted to identify factors affecting job satisfaction. The significance level was 0.05. In regard to salary information, the job satisfaction was found to be high (p<0.001) in cases where the salary was considered appropriate, when incentives were provided, when rewards or vacation expenses were supported, and when overtime and nightly work allowances were paid. In regard to job information, the job satisfaction was found to be high (p<0.001) when the volume of work was considered appropriate, when there were sufficient numbers in the workforce, and when the division of labor among the other personnel was clear. As a factor affecting job satisfaction of dental hygienists, the case of thinking that 'workload is appropriate' was found to be 2.052 times, showing the highest score. Job satisfaction in dental hygienists affects the turnover and has a significant effect on the performance of the organization. Therefore, it is believed, that it is urgent to improve the working environment such as salary and clear division of duties affecting job satisfaction of dental hygienists.

In general, milk is a nutritious food and is very helpful in improving and maintaining a person's health. However, over the past 30 years, a number of studies have reported the presence of Aflatoxin M1 in milk and milk products worldwide. The contamination with Aflatoxin M1 in milk and dairy products has become an important issue all over the world. The presence of the mycotoxin in these products was a major concern particularly among children and infants, who are more sensitive than adults. This study reviewed recent data to summarize the current status of Aflatoxin M1 in milk and dairy products produced in various regions around the world, related regulations, reduction strategies, detection methods, and future research tasks. Strict regulation and superior milk-handling techniques are essential to minimize Aflatoxin M1 contamination in milk and dairy products using ever-evolving analytical techniques. Furthermore, education should be imparted to ensure that Aflatoxin M1 that may exist in milk and dairy products and its effects on human health are made aware of.

This study was conducted to find out basic facts on educational resources in Korea and see how educators have managed their tasks without educational resource archives. The research had the following steps: 1) finding out how the current state of primary and secondary education resources is managed and type of educational resources via Web search and literature review, 2) conducting a survey to determine archiving priorities according to the value of resources to the users, and 3) engaging in a discussion with experts on merits of establishing an educational resource archive system. Due to sporadic management and restricted use of educational resources produced in Korea, the primary and secondary education resources are not easily available to the public even though the public and private sectors produce significant amount of resources. The survey result on preferred educational resource types for archiving showed the following top three: 1) actual case studies conducted in the field, 2) curriculum related resources, and 3) various textbooks adopted. Considering the value of educational resources and the necessity of archiving agencies, the experts recommended to set up a national archiving system of educational resources. This study hopes to raise awareness of the need to set up educational resource archives as a start.

The elderly often produce irrelevant speech and get off-topic more easily than the young; the former also has difficulty generating fewer syntactic structures and makes errors of grammatical morphemes. In particular, the elderly might have more difficulty writing since it requires more complex cognitive processes than storytelling. The participants in this study were 32 young people and 32 older people. They were asked to write a short story of Korean fairy tale('Heungbu Nolbu'). The data was analyzed in narrative composition and syntactic structures. The study revealed the following: First, in composition aspects, the elderly group showed significantly lower total number of story grammar and episodes. In addition, the elderly produced more off topic statements. Second, in syntactic aspects, although there was no significant difference in the number of producing complex sentences between two groups, the elderly group generated more inadequate cohesive devices and used fewer relative and adverbial clauses. These findings suggest that the elderly have a tendency to perform tasks by producing more off-topic statements and shows decreasing coherence by using lower number of relative and adverbial clauses. However, this study also uncovers that the elderly were able to write more complex and longer sentences using visual feedback.

Diadochokinesis (DDK) aims to identify the evaluating the oral mitor ability and the moter coordination ability. There are few DDK normative data on elementary school students in Korea, The purpose of this study was to investigate the characteristics of the speed and regularity of DDK in first- and second-grade students in elementary school. The subjects were a total of 194 students in first- (45 males, 50 females) and second-grade (47 males, 52 females) in elementary schools in Gwangju Metropolitan City. As evaluation tasks, AMR task 'p?', 't?', and 'k?' and SMR task 'p?t?k?' were performed. The speed and regularity of DDK was measured using Motor speech profile (Model 5141, KayPENTAX) and Praat (v6.0.3.6). The results of this study, First, there was a statistically significant difference by grade in AMR speed for 'p?', 't?', and 'k?' and the AMR speed was faster in second grade group. And, there was no statistically significant. Second, AMR regularity showed a statistically significant difference in 'p?', 't?', and 'k?' according to sex and was found to be more regular in female student group. There was no significant difference in regularity by grade. Third, the SMR speed showed statistically significant difference in 'p?t?k?' by grade and was faster in second grade group. And there was no statistically significant difference by sex. The results of this study showed that the DDK performance ability in first- and second-grade students in elementary school was slightly different according to grade and sex. In future research, it is necessary to investigate the correlation between the articulation accuracy and linguistic intelligibility, and to find out the usefulness of DDK in articulation evaluation.

The purpose of this study was to investigate whether a songwriting intervention would improve self-expression of adolescents with cochlear implants (CI). In this study, the songwriting intervention was designed to incorporate previous research findings on music perception of individuals with CIs and to provide musical experiences in which adolescents with CIs could be successful in using music resources for their self-expression. Accordingly, stepwise songwriting procedures were constructed and music technology (i.e., GarageBand as an iPad application) was used. Two adolescents with CIs participated in the intervention once a week for 8 weeks. Changes in level of participation in songwriting tasks, verbal expression, self-reports about the songwriting process were examined. The results demonstrated that the participants showed increased attempts to express themselves via music making. It was also shown that their negative perception of their ability to verbally express themselves decreased. They were observed as becoming more competent in creating music by deciding how various musical elements should be played and making rhythm or melodic patterns by themselves. These results indicate that the songwriting intervention can facilitate self-expression of adolescents with CIs. Further implications in terms of the psychosocial needs of individuals with CIs are presented.

Retrieving temporal information of encoded events is one of the core control processes in episodic memory. Despite much prior neuroimaging research on episodic retrieval, little is known about how large-scale connectivity patterns are involved in the retrieval of sequentially organized episodes. Task-related functional connectivity multivariate pattern analysis was used to distinguish the different sequential retrieval. In this study, participants performed temporal episodic memory tasks in which they were required to retrieve the encoded items in either the forward or backward direction. While separately parsed local networks did not yield substantial efficiency in classification performance, the large-scale patterns of interactivity across the cortical and sub-cortical brain regions implicated in both the cognitive control of memory and goal-directed cognitive processes encompassing lateral and medial prefrontal regions, inferior parietal lobules, middle temporal gyrus, and caudate yielded high discriminative power in classification of temporal retrieval processes. These findings demonstrate that mnemonic control processes across cortical and subcortical regions are recruited to re-experience temporally-linked series of memoranda in episodic memory and are mirrored in the qualitatively distinct global network patterns of functional connectivity.

This study contributes to deepening understand of the characteristics of fishing vessel rolling motions to improve the development of capsizing alarm systems. A time domain rolling motion simulation was performed. In order to verify capsizing alarm systems, it is necessary to carry out experiments assuming a capsizing situation and perform actual fishing vessel measurements, but these tasks are impossible due to the danger of such a situation. However, in many capsizing accidents, a close connection with rolling motion was found. Accordingly, the rolling motion of a fishing boat, which is the core of a fishing vessel capsizing alarm system, has been accurately measured and a time domain based on a rolling motion simulation has been performed. This information was used to verify the algorithm for a capsizing alarm system. Firstly, the characteristics of rolling motion were measured through a motion experiment. For small vessels such as fishing vessels, it was difficult to interpret viscosity due to analytical methods including CFD and potential codes. Therefore, an experiment was carried out focusing on rolling motion and a rolling mode RAO was derived.

Objective: The purpose of this study is to identify the strengths and problems of the current in-service education system, and suggest ways to improve it in the future by looking at the current status of in-service education to strengthen the expertise of teachers and directors of childcare centers. In particular, I would like to search the current status of in-service education, including on-line special job competency education, which is responsible for one of the pillars of in-service education, and present the problems and measures to improve them. Methods: To that end, the present study conducted an analysis of issues based on the previous research on in-service education of childcare teachers' education, and conducted a literature examination focusing on laws, policies, and foreign cases related to in-service education. Results: In-service education for childcare teachers was categorized into educational process diversification and professionalism, educational method diversification, qualification management, and educational support, which were again organized into 14 core tasks. In addition, as a recent phenomenon that has not been discussed in detail in the preceding study, the phenomenon of increased participation in on-line special job competency education at the site of in-service education was analyzed and the problems were presented. Conclusion/Implications: Based on the results of this study, I proposed development measures such as changing the term 'in-service education' and recognizing the diversity of job competency education, the credit rating banking system for job competency education, the provision of on-line job competency education curriculum (basic courses/enhancing courses) for collective education courses, the expansion of education support for promotion to a higher grade courses and the conversion of the mandatory evaluation system for in-service educational institutions.
