Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

This study placed its objectives in suggesting the basic data for setting up an approach to protect the educational environment, by analyzing the relevance between the misconducts of adolescence and the harmful environment around the school, as an object of study, middle school students and high school students all over the country. Thus, this study carried out the questionnaire survey, by the multi-stage of stratified sampling in 2,114 middle school and high school students from June 29, 2000 through July 29, 2000. And the results of analysis were as follows: 1. In case of the ratio of students using harmful environment, the electronic game room had the highest ratio (78.3％); next, the PC room (75.6％), the singing room (71.6％), and the cartoon room (34.3％). 2. In terms of the experiences of using the harmful environment according to the personal characteristics, high school students used it in a higher ratio, compared with middle school students (p〈0.001); the students, whose father graduated from a high school, comparatively used it much more(p〈0.05). Also, when a school is located near to amusement quarters or shopping centers, students used the harmful environment most highly (p〈0.001). And the differences were found to be statistically significant. 3. In case of the perceived susceptibility factors, the harmful environment was found to be used in lower ratio, by the students who answered “very so” to the question item, The more harmful environment facilities are positioned around school, the more student have the opportunities to use them. (p〈0.001). That is, the findings showed that the higher students' degree of perceived susceptibility factors was the less students used harmful environment facilities. The differences were statistically significant. In terms of the ratio of using harmful environment according to perceived seriousness factors, it was founded out that the students, who answered, “If I use any harmful environment facilities, it will be very harmful to myself.”. had the less opportunities of having used them, compared with the students who did not answer so (p〈0.001). This indicated that the higher the degrees perceived seriousness of students, the less they used harmful environment facilities. And the differences were statistically significant. In the side of the ratio of using harmful environment according to the perceived barriers, it was found out that there were any special large differences. That is, perceived barriers had nothing to do with students' using harmful environment. 4. As the result of having analyzed the factors influencing the behaviors of using harmful environment, the factor to explain the behaviors of using harmful environment was found to be the degree of perceived seriousness, among individual perceiving factors; next, the location of a school - one of personal characteristics, the degree of perceived susceptibility and ages, m sequence. 5. Among students' misconduct experiences, drinking was highest (21.6％), next, smoking (11.9％), drug abuse (4.3％), and sexual relations (1.6％), In sequence. Among other problematic behaviors, excessive waste was highest (14.6％); next, disobedience and lie (10.7％), night wandering (7.8％), and bad dressing and making-up (5.5％), in sequence. 6. In terms of the misconducts according to the behaviors of using harmful environment, compared with the students who did not commit any misconducts, harmful environment facilities were used more highly, by each group of students who experienced drinking (p〈0.00l), smoking (p〈0.001), sexual relations (p〈0.05), excessive waste (p〈0.001), disobedience ＆ lie (p〈0.001), and bad dressing ＆ making-up (p〈0.05).

The study was carried out to understand the inhabiting status and biological features of nutria (Myocastor coypus) in the Jeju Island from May, 2013 to August, 2016. Five individuals were captured by traps and two individuals were collected in dead. Of the 7 individuals, those whose bio-information could not be known were excluded to perform autopsy of the rest of them. The results from morphological, cranial and anatomical analyses, it was found that the females achieved sexual maturation but had no breeding experience. An adult male showed similar sizes to those found in the Korean Peninsula. After collecting the 7 individuals in 2013, 1 nutria individual was filmed by the scouting camera in May, 2014 but not captured. The long-term investigation of the research area found no inhibiting individual. It is deemed the nutria was either died of natural death or migrated. In order to establish a proper nutria control, the environmental characteristics of Jeju Island should be considered where indigenous and introduced species coexist in a limited space. Our findings will provide helpful information for understanding biological features of nutria and planning protection program of natural ecosystems of Jeju Island.

Objectives: The purpose of this research is to find out the relations among children‘s perceived competences, expressive disposition of interpersonal relations, and parents’ social support, which influence their self image. Methods: The samples to achieve the purpose of this research are composed of 294 students in G elementary school, OO city, Kyounggido, the number of male students in the fifth year being 71, female 77, and male students in the sixth year being 73, female 73. After having excluded the data of 9 students among them due to their insincere reply, this research analyzed the data of 285 students by using SPSS WIN Ver. 13.0. Results: First, after having observed the average difference stemming from each method, this research found that there is no sexual difference in parents‘ social support. (p<.05). In children's perceived competences, female students is higher only in active aspect than male students, but there is no meaningful difference in other aspects. In expressive disposition of interpersonal relations, the showing-off and narcissistic expressive tendency of female students is higher than that of male students, but there is no meaningful difference in other aspects. Second, this research found out the meaningful static correlation among parents' social support, children's perceived competences, and expressive disposition of interpersonal relations. Parents' emotional, appreciative, and informative support has the static correlation with all the other aspects of children's perceived competences, and material support has the static correlation with children's academic, active, and general self-esteeming sense (p<.05, p<.01). Third, this research observed, of all the aspects of parents' social support and expressive disposition of interpersonal relations, what variable is affecting children's perceived competences, and found that parents' appreciative support, showing-off and narcissistic expressive tendency, material support, and informative support, each in order, has meaningful influence (p<.05, p<.01). This fact shows that the further the children recognize these supports of their parents', the more affirmatively they recognize their competences, and the further the children of showing-off and narcissistic expressive disposion recognize their competences. Conclusions: First, sampling was conducted of the fifth and sixth male and female students of OO elementary school, and so the result of this research has the applicative limitation in the generalization for all the elementary school students. Therefore this research suggests further researches by broad sampling for the more advanced generalization. Second, this research only observed the differnce of perception deriving from gender and school year, but the parents' social support levels perceived by children reveal many differnces according to children's characters or their families' variables. Therefore this research suggests subsequent researches on various variables.

Objective : This study examined the socioeconomic differentials for the health and health related behaviors among South Korean middle school students. Methods : A nationwide cross-sectional interview survey of 3,449 middle school second-grade students and their parents was conducted using a stratified multi-stage cluster sampling method. The response rate was 93.3%. The socioeconomic position indicators were based on self-reported information from the students and their parents: parental education, father's occupational class, monthly family income, out-of-pocket expenditure for education, housing ownership, educational expectations, educational performance and the perceived economic hardships. The outcome variables that were measured were also based on the self-reported information from the students. The health measures included self-rated health conditions, psychological or mental problems, the feelings of loneliness at school, the overall satisfaction of life and the perceived level of stress. The health related behaviors included were smoking, alcohol drinking, sexual intercourse, violence, bullying and verbal and physical abuse by parents. Results : Socioeconomic differences for the health and health related behaviors were found among the eighth grade boys and girls of South Korea. However, the pattern varied with gender, the socioeconomic position indicators and the outcome measures. The prevalence rates of the overall dissatisfaction with life for both genders differed according to most of the eight socioeconomic position indicators. All the health measures were significantly different according to the perceived economic hardship. However, the socioeconomic differences in the self-rated health conditions and the psychosocial or mental problems were not clear. The students having higher socioeconomic position tended to be a perpetrator of bullying while those students with lower socioeconomic position were more likely to be a victim. Conclusions : The perceived economic hardships predicted the health status among the eighth graders of South Korea. The overall satisfaction of life was associated with the socioeconomic position indicators. Further research efforts are needed to explore the mechanisms on how and why the socioeconomic position affects the health and health related behaviors in this age group.

In order to research into the devel of the concept of movement and speed in our own way and compare with the Piaget's method, and then find out the formative period of such development, we have put the 192 primary school children as the model and obtained the following results. 1. As their grade upyards, all the experimental subjects showed the gradual progress generally regardless of sex or regions, while only the relative speed showed irregular progress. 2. There was no experimental subject which showed any remarkable sexual characteristics. But in the relative movement, the lower grade boys and higher grade girls made progress. In the subjects of circulation movement, intuition of speed, relative speed and speed of simultaneous movement, the boys marked better progress, whilst the girls were advanced a little in the speed of continuous movement with, different distance and time. 3. There was no conspicuous difference between the urban and rural areas, except a slight tendency that the urban children made better progress in the change of progressing direction, native continuous procedure of periodical movement, travelling road, and the speed of continuous movement with different distance and time whereas the rural children were more advanced in the relative movement, relative speed and intuition of speed. But it should be 'taken into consideration that the rural regions in our case were relatively developed in comparison with the traditional rural communities, which may explain about little regional difference. 4. Comparing our research results with the Piaget's theory, we have reached below results. Our research reports that the formative period of the conception of the problems of diverse progressing direction and a native continuous procedure of periodical movement was simultaneous, at the Piagetian level(at the fourth grade) which coincides with Piagetian theory. The travelling road should be made up a little lower at 2A/2B according' to Piagetian Level, whereas it was formed at the 4th grade as shown in our previous research. Intuition of speed should belong to the prior stage to concrete operation, but our research shows it was formed late at the 4th grade. Composition of displacement was made at the 6th grade, and it was almost equal to the first stage of formal operation(3A). But in the subjects of relative movement relative speed, the speed of continuous movement with different distance and time, relation and preservation of invariable speed, and accelerated motion, even 6th grade children marked a poor record. Summed up, the procedure conception as a basic movement conception coincides with the Piagetion level. But as for speed intuition, relative speed and speed fixation, it was Jar behind Piagetian level. Therefore it is required that we have to concentrate on the systematic training in these parts on the spot.

This research was conducted to understand and analyze the health-related behaviors of middle school students and get fundamental research data essential to provide efficient student guidance and public health service at school. The interview using Youth Risk Behavior Surveillance System(YRBSS). Translation and modification for Korean students of the YRBS. The Korean version of YRBS(Youth Risk Behavior Surveillance System) that translation and modification for Korean students of the YRBS developed by the Centers for Disease Control and Prevention(CDC)was used to assessment to health-related behaviors of youth. The interviewees were 1040 enrolled students at middle school in Daegu metropolitan city. YRBSS monitors six categories of priority health behaviors among youth and young adults behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use, sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases(STDs)(including human immunodeficiency virus infection); unhealthy dietary behaviors; and physical activity. The result shows that over 30% of students rarely or never used safety belt and almost students were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 21.9% female students had felt so sad or hopeless almost every day for $\geq$ 2weeks in a row that they stopped doing some usually activities 20.5% of male middle school students have ever tried cigarette smoking. 26.2% of male students and 27.2% do female students had had over one drinks of alcohol during their lifetime(lifetime alcohol use). 47% of male students had had over one drinks of alcohol on $\geq$ 1 of the 30 days preceding the survey(current alcohol use). Over one half of female student were thought they were overweight. These results suggest that some risk behaviors be very prevalent in a korean middle school students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during middle school age, extend into adulthood, are interrelated. Among both children and adults, the leading causes of death are closely linked to these behaviors. Among adults, chronic diseases such as cardiovascular disease, cancer, and diabetes are the national leading killers. Practicing healthy behaviors, such as eating low-fat, high-fruit-and-vegetable diets, getting regular physical activity, and refraining from tobacco use, would prevent many premature deaths. Because health-related behaviors are usually established in childhood, positive choices need to be promoted before damaging behaviors are initiated or become ingrained.
