Purpose: The purpose of this study was to investigate factors influencing internet addiction proneness and condition of internet use in higher grade students at an elementary school. Method: The subjects consisted of 234 sixth grade students at an elementary school in Gyeonggido. SPSS/Win18.0 was used for analysis of data. Results: Among the subjects, 51.3% had used the internet for more than three years, 89.3% used the internet in their home, and 38.5% used the internet for games. In internet addition proneness, 3.1% were potential risk users and 1.3% were high risk users. Internet addiction proneness differed significantly according to gender, period of internet use, internet access location, and purpose of internet use. Internet addiction proneness showed negative correlation with protective factors and positive correlation with risk factors. The factors affecting the internet addiction proneness were degree of internet use, peer protective factor(support from peer), personal protective factor(self-control), internet access location, and family risk factor(negative communication). These factors accounted for 32.9% of internet addiction proneness. Conclusion: Strategies are needed for improvement of the relationship with the peer group and family communication and to encourage self-control for prevention of internet addiction in elementary school students in community mental health service.

Nanotechnology is the fastest growing area in scientific research and it has important applications in a wide variety of fields. Nevertheless, consumers encountered this new technology without any identification of risks and benefits. Also until now, there are no specific safety evaluation methods for nanotechnology. For this reason, we studied risk communication strategy for nanotechnology to prepare its application in commercialized products on public. A survey was conducted to identify the differences in perception between public (N=110) and expert (N=37) toward applied nanotechnology in food, drugs and cosmetic products. The survey results were used to draw up a risk cognitive map which was introduced by Paul Slovic, and the perception level of public and expert on nanotechnology was evaluated. As a result of the survey, public recognized nanotechnology as "unknown but low dread" risk factor, but expert recognized it as "unknown and high dread" risk factor. These results indicate that there are perception differences between two groups. Several risk communication strategies are reported including care, consensus and risk communication. In the case of nanotechnology, it contains both risks and benefits. Considering the nature of nanotechnology, the "consensus communication" which informs consumers about risks and benefits of issues is the most appropriate strategy.

This study intended to investigate the concept of Clothing Involvement and Brand and to provide useful basic data for building on affective brand strategy. The purpose of this study is as follows: first, It is to measure the result of Brand Extension attitudes and Brand Extension items by clothing involvement (high involvement/low involvement). Second, It is to classify the factors of Clothing Involvement which suggested in theoretical research and to clarify correlation between clothing involvement factor and brand evaluation, brand extension attitudes. Third, It is to investigate the affect that clothing involvement, demographic variable and brand type on Brand Extension Evaluation. Subjects of this study were the adult women in Seoul, who were extracted by sampling randomly during the fall of 1995. Questionnaire was used as major method of gathering data. They were analyzed by the SAS method such as Frequency, Anova, Duncan, Correlation, multiple regression, Factor analysis. Main result of this study were as follows : 1. In brand extension attitude evaluation by high-involve group and low-involve group, quality, reputation and buying intension of brand extension attitudes showed significant difference. B brand extension attitudes and items of high-involve group was high compare to low-involve stoup. High-involve group evaluated watch, underwear, shoes and stocking of extension items highly, and there is no involvement difference of perfume, parasol, cushion. 2. In order to classify the dimension of Clothing Involvement, it was carried out factor analysis. 1 found that Clothing Involvement was composed of 4 factors, namely, interest - fashion.perceived risk symbolism. Correlation between clothing involvement and brand extension attitude was as followed; Interest factor of clothing involvement was correlated the existing brand attitude. Brand preference of the existing brand attitude was related the image of brand extension attitude, interest of advertising was the quality and the reputation-image was the buying intension. 3. For evaluation of a factor influenced on Brand Extension, it was produced multiple -regression test. Demographic variables and brand types had some influence of Clothing Involvement and Clothing Involvement had on brand extension. 27% of interest, 26% of symbolism was explained by brand types and 15% of fashion, 6% of perceived risk was explained by brand types, demographic variables. And, 10% of brand extension was explained by interest, fashion and symbolism.

The purpose of this study is to investigate the effect of quality of management discussion and analysis (MD&A) disclosure on stock price crash risk. The MD&A can be seen to reflect the management's intention on public announcement and reveals directly what the management says to communicate with outside investors. A firm's high-quality MD&A implies the management's commitment to communicating with the market, not allowing the managers to have incentives to hoard unfavorable news, which if revealed to the public, may lead to downward stock price corrections, damaging corporate values. The high-quality MD&A is, thus, likely to reduce the stock price crash risk. We use a logistic regression to test whether MD&A influences crash risk using listed companies in the Korean Stock Exchange (KSE) stock market between 2010 and 2013. Findings of the empirical test show that the higher the quality of MD&A, the less likely crash risk appears, implying that the MD&A disclosed adequately can be one of the factors mitigating firm's stock price crash risk. This study has implications as it presents the MD&A disclosure as a factor influencing stock price crash risk and suggests voluntary disclosure as well as mandatory disclosure acts as a variable that explains the risk of stock price crash.

The seroprevalence of human toxoplasmosis has been increasing in Korea, and it is controversial whether cats are an important infection source or not. This study was performed to evaluate the seroprevalence of Toxoplasma gondii infection in a high risk group (cat sitters) and to determine the possible importance of cats as an infection source in Korea. Risk factors, including the age, sex, and diet of cat sitters, their contact experience and contact frequency with stray cats, and origin, number, and outdoor activity of their pet cats, were analyzed using structured questionnaires. A total of 673 serum samples from people who have frequent contact with cats (high risk group) and 1,114 samples from general people (low risk group) were examined for specific IgG antibodies against T. gondii by ELISA. The results revealed that the overall seroprevalence of T. gondii infection was 7.4% (n=1,787). The seroprevalence among low risk group was 8.0% (89/1,114), whereas that among high risk group was rather lower 6.4% (43/673), though this difference was statistically not significant (P=0.211). Among the risk factors, only the outdoor activity of pet cats was important; people having cats with outdoor activities revealed 2 times higher seroprevalence than people having cats with only indoor activities (P=0.027). In conclusion, the seroprevalence of T. gondii was not significantly different between the high risk group and low risk group, and the importance of cats as a source of infection in Korea is questionable.

Objective : Studies have suggested that beer is associated with a high risk of mortality and morbidity. The purpose of this study was to investigate how types of alcoholic beverage are related to high risk acute harm. Methods : Data from the 1997 Korea's Behavioral Risk Factor Surveillance System Survey, collected through telephone questionings, were analyzed based on multi-stage stratified random sampling(N=1,045). Among those who had drunk at least one type of alcoholic beverage in the last month, one episode where the drinker had consumed the highest level of ethanol was selected, and the alcohol consumption per drinking day categorized into four risk levels of short-term, 'acute' harm, according to the WHO guidelines. Employing ordered logistic regression analyses, as the explanatory variables, types of alcoholic beverage, with and without socioeconomic characteristics, were considered. Results : Spirits and soju were more than ten and three times, respectively, more likely than beer, while makkolli and wine were almost as likely as beer, to involve high risk drinking, irrespective of controlling for the socioeconomic characteristics. Conclusions : Unlike most Western countries, in Korea, beer, rather than spirits or soju, is generally less likely to be associated with high risk drinking for acute harm, The influence of beverage types on high risk drinking for acute harm appears to vary between countries.

The purpose of this study was to present the empirical data for the prevention of suicide by analyzing the group differences according to the types of risk factors and protective factors of family members living with dementia patients and the effects of each type on suicidal ideation. This study investigated the characteristics of suicidal ideation among family members of people living with dementia by using a community health survey. It then investigated the effect of each latent group on the suicidal ideation of family members of people living with dementia. Twenty-four risk and protective factors on suicide ideation were analyzed by using Mplus. The four latent classes were high risk - low protective, high risk - high protective, low risk - high protective and low risk - low protective. Multivariate logistic regression analysis showed that the high risk-low protective factor group had the highest suicidal ideation. Based on these results, practical implications and challenges were presented.

Recently, not only around Korea but also other countries shows a pattern of arising high-rise building construction project which was delayed or aborted during global economic crises and recession. Although the market starts to stretch, It is getting competitive to win a contract in high-rise construction project between contractors due to lack of competitive advantage especially to Korea contractors. To get that, Korean contractors needs lifting equipment plan. But currently, they depend on the empirical methods and that cause schedule delay, not controlled cost management problem. Therefore, this research is to improve the accuracy of Lifting plan by analyzing the current issues of Lifting plan system and deducing the types of failures with planning factors, as well as analyzing the impact on schedule and cost control and safety management by each failure mode. Also, by analyzing detail risk factors per Lifting Equipment with FMEA, to infer the critical risk factor on high-rise construction project.

Background: There are regional variations in the incidence of coronavirus disease 2019 (COVID-19), which means that some regions are more exposed to the risk of COVID-19 than others. Therefore, this study aims to investigate regional variations in the incidence of COVID-19 in Korea and identify risk factors associated with the incidence of COVID-19 using community-level data. Methods: This study was conducted at the districts (si·gun·gu) level in Korea. Data of COVID-19 incidence by districts were collected from the official website of each province. Data was also obtained from the Korean Statistical Information Service and the Community Health Survey; socio-demographic factor, transmission pathway, healthcare resource, and factor in response to COVID-19. Community risk factors that drive the incidence of COVID-19 were selected using a least absolute shrinkage and selection operator regression. Results: As of June 2021, the incidence of COVID-19 differed by more than 80 times between districts. Among the candidate factors, sex ratio, population aged 20-29, local financial independence, population density, diabetes prevalence, and failure to comply with the quarantine rules were significantly associated with COVID-19 incidence. Conclusion: This study suggests setting COVID-19 quarantine policy and allocating resources, considering the community risk factors. Protecting vulnerable groups should be a high priority for these policies.

Background: This study was conducted to provide preventive measure for the musculoskeletal disorders in automobile parts manufacturing workers. Method: The author surveyed to the musculoskeletal symptoms prevalence and its related factors from 10th to 17th April 2011 with structured self administered questionnaires. 223 out of 225 collected questionnaires were used for final analysis, excluding 2 questionnaires with no valid response. Based on the diagnostic criteria of NIOSH (National Institute for Occupational and Health), an investigation was made into the prevalence of musculoskeletal symptoms as well as into the factors related to individual items. Results: The prevalence of musculoskeletal symptoms according to the criteria of NIOSH was the highest in the shoulder (52.9%), followed by the neck (39.%), the hand/wrist (35%), the waist (29.6%), the arm/elbow (24.7%), and the leg/food (23.8%). One-way analysis showed that among general characteristics, age was the musculoskeletal risk factor with the greatest effect. Whereas among work-related characteristics, significant risk factor didn't find. Yet it was shown that among ergonomic work postures, high degree of musculoskeletal risk was shown by the posture involving frequent and repetitive movement of the arm and the hand/wrist and also by the posture involving standing for a long time. Multiple regression analysis showed that musculoskeletal risk was 1.795 times higher in those age 50 and over than in those under age 50; 1.67 times higher in the high risk stress group than in the low risk stress group; and 1.131 higher in the group involving the repetitive use of the hand/arm than in the other groups (p<.05). Conclusion: The prevalence and stress score of automobile parts manufacturing workers were higher than other occupation workers. Among general characteristics, drinking and smoking were shown to be related to stress score; while age was shown to have significant effect on musculoskeletal risk.
