This paper proposes a customized AI exercise recommendation service for balancing the relative amount of exercise according to the working environment by each occupation. WISDM database is collected by using acceleration and gyro sensors, and is a dataset that classifies physical activities into 18 categories. Our system recommends a adaptive exercise using the analyzed activity type after classifying 18 physical activities into 3 physical activities types such as whole body, upper body and lower body. 1 Dimensional convolutional neural network is used for classifying a physical activity in this paper. Proposed model is composed of a convolution blocks in which 1D convolution layers with a various sized kernel are connected in parallel. Convolution blocks can extract a detailed local features of input pattern effectively that can be extracted from deep neural network models, as applying multi 1D convolution layers to input pattern. To evaluate performance of the proposed neural network model, as a result of comparing the previous recurrent neural network, our method showed a remarkable 98.4% accuracy.

The purpose of this study was to examine the impact of internal marketing on the job satisfaction and turnover intention of dental hygienists. A self-administered survey was conducted on the selected dental hygienists, and the statistical package SPSS 12.0 was employed to analyze the collected data. The findings of the study were as follows: 1. The performance of internal marketing took place more often among the dental hygienists who belonged to the other workplaces. Those who had three to less than five years of experience at their current workplaces were more aware of the importance of education and training. 2. The dental hygienists who were aged between 26 and 35 and who belonged to the other workplaces and who had five to less than 10 years of experience in total expressed the best job satisfaction. And the strongest turnover intention was found among those who had one to less than three years of experience in total or at the current workplaces. 3. As a result of analyzing the correlation of those variables, better performance of internal marketing led to better job satisfaction, and better performance of internal marketing and higher job satisfaction led to less turnover intention. 4. The factors of internal marketing performance that exerted an influence on job satisfaction were communication and welfare benefits, and the variables that affected turnover intention were education/training and the reward system that belonged to the performance of internal marketing.

In this study, we tried to find ways to minimize the negative effects of workplace bullying by analysing how workplace bullying affects private security guard's job attitude. The results of survey are as follows. First, as the result of analysis how the guard's workplace bullying affects job satisfaction, one of the job attitude, it showed that relational aggression and workplace bullying have a negative effect on their job satisfaction. In other words, job satisfaction decreases as relational aggression and workplace bullying increase. Second, as the result of analysis how the guard's workplace bullying affects their turnover intention, we found that relational aggression and workplace bullying have an effect on turnover intention, especially, relationally workplace bullying has a more effect on their turnover intention than relational aggression, which Is somewhat different from other studies. Study shows that workplace bullying can cause the guard's negative respond and behavior on their job satisfaction, they have to consider transferring another job. Therefore, increasing their job satisfaction and decreasing turnover intention are very important as we are exposed to crimes these days. In this study, we have come with following solutions. First, to increase job satisfaction against workplace bullying, we have to raise the efficiency of their human resources and reduce work ambiguity of actual work burden caused by positive organizational atmosphere and clear responsibility. Second, it is needed to promote personnel exchange between departments and form partnership through regular meetings by targeting common goals to concentrate same interests. At the same time, we have to improve the guard's welfare and working environment by introducing psychological counselling to the victims of bullying.

This study analyzes human error of workers performing simple repetitive tasks, and in order to prepare preventative measures, 486 people were used as subjects. The results of the study are like the following. First, the biggest cause of human error showed to be the worker himself in $77.8\%$ of the cases, machinery showed to be the cause in $16.3\%$ of the cases and management showed to be the cause in $6.0\%$ of the cases. The results show that most of the human error occurred due to the worker performing simple repetitive tasks and the human errors showed to be caused more by bad ergonomics and long hours rather than by problems with machinery. In addition, the area with the highest rate of human error showed to be the Human Information Processing System with Task Input Error being the highest with $46.9\%$, followed by Judgement and Memory Error with $36.4\%$ and Recognition Verification Error with $16.7\%$. Although fully automated tasks may reduce the rate of human error we must focus on lowering the rate of problems arising from spontaneous errors caused by workers performing simple repetitive tasks by continuously renewing plans and budgets in order to standardize tasks by incorporating cyclic positioning according to experience and positional exchange and by inspecting the workplace to increase efficiency of the workers.

The purpose of this study was to present the direction of the safety manual in the food service industry kitchen. The accident rate in food industry kitchens is around 87.2%, it meaning nearly 9 workers have accident among 10, considered to be very high. The most common accident is a knife cut wound (84.7%). And burns caused by hot water and oil (74.4%), then shown slip and falls (28.1%). The degree of fulfillment of kitchen safety awareness and safe environment varied based on gender, in which male are considered more likely to suffer from accidents than women. The level of safety perception varies between workers at different career points. Workers with 1~3 years of experience suffer the highest rate of accident, while workers with 7~10 years and more of experience are believed to be at lower risk of accident. Restaurant type did not exhibit a significant influence on accidents cases, although differences in the adoption of personal safety, even partially, were discovered, at significance of 0.01 < 0.027 < $0.05^*$. Based on these results, this paper has suggested preventive safety management validation model the food service industry based on kitchen management and incident management, and presented steps necessary.

Circadian rhythm is controlled by hormonal oscillations governing the physiology of all living organisms. In mammals, the main function of the pineal gland is to transform the circadian rhythm generated in the hypothalamic suprachiasmatic nucleus into rhythmic signals of circulating melatonin characterized by a largely nocturnal increase that closely reflects the duration of night time. The pineal gland has lost direct photosensitivity, but responds to light via multi-synaptic pathways that include a subset of retinal ganglion cells. Rhythmic control is achieved through a tight coupling between environmental lighting and arylalkylamine-N-acetyltransferase (AANAT) expression, which is the rhythm-controlling enzyme in melatonin synthesis. Previous studies on the nocturnal expression of AANAT protein have described transcriptional, post-transcriptional, and post-translational regulatory mechanisms. Molecular mechanisms for dependent AANAT expression provide novel aspects for melatonin's circadian rhythmicity. Extensive animal research has linked pineal melatonin for the expression of seasonal rhythmicity in many mammalian species to the modulation of circadian rhythms and to sleep regulation. It has value in treating various circadian rhythm disorders, such as jet lag or shift-work sleep disorders. Melatonin, also, in a broad range of effects with a significant regulation influences many of the body's physiological functions. In addition, this hormone is known to influence reproductive, cardiovascular, and immunological regulation as well as psychiatric disorders.

The $^{18}F$-FDG is one of the widely used isotopes for PET/CT scans. Dose amount injected to the patient depends on the characteristics of PET/CT systems. Obviously, the technologists who contact with patients would be exposed as well. In this study, we evaluated the exposed dose of the technologist who works on the PET/CT scanner. The exposed dose were measured every month with the TLDs from 6 technologists. Each technologist is shift-worker who manages 3 different PET/CT systems(Scanner 1(S1): 0.15 mCi/kg, Scanner 2(S2): 0.17 mCi/kg, Scanner 3(S3): 0.12 mCi/kg). The average exposed doses of technologists for each PET/CT system were measured as 0.76 mSv for S1, 0.93 mSv for S2 and 0.47 mSv for S3. The maximum dose was 1.12 mSv and minimum was 0.42 mSv. The results showed that there was a correlation between exposed dose and PET/CT system(p<0.005). Less injected dose for patient occurs less exposed dose for technologist. Various studies for the low dose PET/CT system are required for not only the patient but also the technologist.

The purpose of this study was to seek practical intelligences for certain persons who wish to be a guard by studying for what practical public guards' recognition of organization and vocation is. The results of this study were as follows. First, Six study participants presented 'Respect within members', 'Atmosphere like family', 'Premium members', and 'Economic compensation & wealth of budget' as essential requirements for the best guard organization. Second, they also presented 'Systematic daily task & training', 'Exact selection system', and 'Strong cohesion & teamwork' as strong points of their organization. Third, they mentioned 'Internal evaluation system', 'Lack of education contents', and 'Limited position circulation' as weak points of their organization. Fourth, they mentioned that they feel encouraged itself as they work in the best guard organization, while they were skeptical when the citizens did not cooperate with them and they were not fully rewarded for their injury. Fifth, they expressed 'Difficulty of business cooperation', 'Unstable living patterns', 'Inconsistent assessment', and 'Continuing tension' as difficulties for performing the duties and stress causes. Lastly, they recognized of job security and self-esteem as they work in the best guard organization as advantages of a job, while they recognized of controlled life, low salaries and welfare level compared to duty importance and risks as disadvantages of a job. Consequently, students who wish to be a guard should consider job and organization attributes and set their career goals refer to these results.

This study aims to examine that Jeollabuk-do 14 cities and counties's job creation policy would lead to a virtuous circle of the local economy through measuring the ratio of spatial mismatch. We suppose that the higher proportion of spatial mismatch in a city or county is, the lower multiplier effect contributes the local economy, especially in the income of residents and the influx of population. For the analysis, this study uses Korean Regional Employment Survey Micro-data and calculates the labor demand self-sufficiency(LDSS) rate of every local labor market for measuring the degree of spatial mismatch. Also we calculate the LDSS rate of employment status, industry, job classification and wage for testing the independency of local labor market. After analyzing, just Jeonju, Gunsan, Iksan, and Namwon could be regarded as independent local labor market where LDSS rates are above 75% in most criteria. But other local labor markets depend on outer labor supplies. For the development of regional economy, it is necessary to consider the creation of 'good jobs' that can induce the labor in parallel with the quantitative increase of employment.
