  • Finding causes of workers' unsafe behaviors is important to prevent construction accidents because 80 percent of accidents occur by workers' unsafe behaviors. In this regard, this research aims to investigate possible reasons of workers' unsafe behaviors based on workers' cognitive process model using System dynamics. This study is based on two ways of workers' cognitive process which are in relation to hazard perception and failure of hazard perception. Based on existing literature, causal loops for workers' cognitive process are developed to explain workers' habituation by staying out of accidents, safety learning by experience, failure of hazard perception, and attitude change by accidents. The interactions between the developed loops provide managerial insights to reduce workers' unsafe behaviors from a safety manager's perspective including increasing the probability of workers' hazard perception through knowledge management, maintaining workers' positive attitude toward safety, and controlling first-line supervisors to eliminate workers' unsafe behavior. The research allows us to better understand the causes and solutions of workers' unsafe behaviors in workers' cognitive perspectives.

  • It is necessary that current oral health education should be not only focused on grade schoolers, but provided for even junior and senior high schools on regular basis in favor of higher level of knowledge about dental health and the habituation of oral health promotion behaviors. So this study took total 288 respondents as sample from Grade 3 of 'C' high school(Suncheon city, Jeonnam) to examine their experiences in oral health education, their awareness of needs for oral health education and their demands for oral health education in the interest of providing basic materials for effective oral health education. 1. As the result of researching health awareness, 13.9% respondents answered that they didn't have good total body health, while 33.3% respondents felt that they didn't have good oral health. That is, more respondents felt that their oral health is not good, rather than total body health is. 2. For daily toothbrushing frequency, it was found that most respondents(62.6%) brushed their teeth 3 times a day, And for toothbrushing methods, it was found that 35.5% used manual toothbrushing(up-and-down toothbrushing movement) and 30.0% used semi-automatic toothbrushing(rotational movement). On the other hand, majority(89.4%) of respondents conducted tongue brushing, but only 10.8% benefited from dental examination on regular basis. 3. 28.1% respondents had experiences in oral health education. Out of them, 69.3% felt moderate satisfaction at the education. Majority(91.2%) of respondents were instructed once in oral health education, and 82.7% respondents were instructed in the oral health via practices(toothbrushing guidance). 77.8% respondents were instructed in the oral health at dental clinics. 4. As the result of surveying demands related to oral health education, 92.3% respondents answered that they need regular oral health education, and 82.9% respondents answered that they need oral health technicians in school. And 87.8% respondents needed individual oral health education for the benefit of better oral health.

  • This study was conducted to investigate bird community and to suggest a proper way how to manage and protect wildbirds in Chuwangsan National Park. The survey was carried out over two survey sections by the line transect method in spring, summer and autumn in 1994. Total number of observed birds were 42 species(33 species in spring, 32 species in summer, and 26 species in autumn), and the result was the same with the typical pattern of temperate bird communities. Total number of natural monument and rare birds were 7 species, which included Golden Eagle(Aquila chrysaetos), Chinese Sparrow Hawk(Accipter soloensis), Eagle Owl(Bubo bubo), etc. In breeding season, species richness was high in canopy nesting guild, and density(ea/ha) was high in hole nesting guild. Canopy foraging guild was dominated in spring and summer, ratio of bush(or ground) foraging guild was increased in autumn. Since the habitats of observed natural monuments and rare species were roughly overlapped with the nature preservation area, it is necessary to preserve the area completely and to investigate and protect these species continuously. For the protection of the bush(or ground) foraging guild, it needs to plant bushes around trails and to control users. Food plants, artificial food planting of bushs, and artificial nest are needed for the habituation of wildbirds, and as the damage of wild cats is increasing lately, it needs to control these cats.

  • The purpose of this study is to explore the fundamental nature and meanings of the experiences of university students with regard to their smartphone usage in order to prevent smartphone addiction and provide guidelines to develop effective interventions. Nine university students who were currently enrolled in an university located in a Korean province participated in this study. In-depth interviews were conducted from June of 2012 to July of 2012, and data were analyzed using Colaizzi's phenomenological qualitative method. As a results, five theme and 40 subthemes of experiences of problematic smartphone usage were identified. Those themes include 1) a desperate try to connect with others(exposing oneself without appropriate self-protection, seeking emotional comfort, hurt and mistrust); 2) excessive use of smartphone and loss of self-control(more smartphone usage over computer/over-immersion/excessive usage/habituation, loss of self-control); 3) psychological difficulties(excessive attachment and dependence, separation anxiety, clingingness, reduced patience) ; 4) threats to daily functioning (changes in priorities, regressed independent daily functioning, irregular daily patterns, health problems, interruptions from free messenger, academic difficulties); 5) potential for recovery(conflictual feelings and doubts over smartphone usage, importance of interpersonal(face-to-face) communications, willingness to cut down the use, hope for recovery). This study provided suggestions for the prevention effort against smartphone addiction.

  • Objectives:This study evaluated the association between behavioral characteristics and polymorphisms in DAT1, DRD2, DRD3, and DRD4 genes. Methods:The subjects were 114 neonates, who were born by normal spontaneous vaginal delivery and had no physical problems. The behavioral characteristics were evaluated using Neonatal Behavioral Assessment Scale(NBAS) at $17.8{\pm}7.0$ hours after their birth to minimize environmental influences, and cord blood was used to analyze the gene polymorphisms. Results:In comparison to DAT1 gene 10/10 genotype group(N=93), other genotype group(N=19) showed significantly high NBAS scores on social-interaction, state organization, and state regulation. DRD2 gene Ser311/Cys311, TaqI A, and TaqI B polymorphisms showed no significant differences on NBAS scores when they were grouped by genotypes. DRD3 gene polymorphism and DRD4 gene promotor polymorphism showed no significant difference on NBAS scores when they were grouped by genotypes. In comparison to the short repeats(N=102), long repeats(N=10) in DRD4 gene showed significantly high habituation score of NBAS. Conclusion:These results suggest that the genetic effects of the neonatal behavioral characteristics may be mediated via DAT1 and DRD4 genes.

  • Maintaining active users who repeatedly share high-quality knowledge is critical for the success of online Q&A sites. This study suggests two paths that lead to active users' continuous knowledge sharing: 1) elaborated decision process, represented by continuance intention, and 2) automated cognitive process, represented by past behavior. The direct and moderating effects of continuance intention and past behavior were verified by analyzing subjective intention data and objective behavior data of 333 active users of Naver Knowledge-iN. Using Cox proportional hazards regression and negative binomial regression, the influences of continuance intention and past behavior on two types of continuous knowledge sharing were examined. The results showed that only past behavior was significantly influential on knowledge sharing continuance and as to the frequency of knowledge sharing, both continuance intention and past behavior's influences were significant. It was also confirmed that past behavior negatively moderates continuance intention's effect on the frequency of knowledge sharing. In order to maintain active users' continuous knowledge sharing, it is important to habituate knowledge sharing through repetitive knowledge sharing behavior. And in order to increase the frequency of knowledge sharing, in addition to the habituation, appropriate benefits that can increase the continuance intention should be provided.

  • This study was conducted for behavioral characteristic analysis of the Asiatic Black Bear in a limited space. Behaviors of eight Asiatic Black Bears were classified into 13 normal stances and locomotor activities, 15 normal maintenance behaviors, 9 locomotory compulsive behaviors, 2 non-locomotory compulsive behaviors through the 3 years of monitoring. The bears had originally been released into the Jiri National Park for Asiatic Black Bear Restoration Project and were withdrawn again because of several reasons such as habituation to humans, and apiary damage. Through the monitoring of 6 hours per day during 3 months, classified behaviors were analyzed based on sex, age, observing month, observing timing, captivity period, and captive form. The total rate of stereotypic behaviors was $26.51{\pm}13.38%$. Among these, RA(Rest_A) was rated high as $47.32{\pm}18.32%$. In addition, SP(Standard pace), HR(Head rear), EP(Extended pace) were most frequently observed behaviors. The time budget of TFS(Two feet stand), SA(Sniff_A) and SB(Sniff_B) on females and younger individuals were relatively higher than male and older individuals. So we confirmed that females and younger individuals had more wariness and curiosity. As the period of captivity took longer, the rate of stereotypic behaviors was higher and more stereotypic behaviors were observed in the afternoon. At night, behaviors related with resting like Rest-A, Rest-B, Lying down, Lying on abdomen, Sitting were more frequently observed. We concluded that the captive state could affect the behaviors of Asiatic Black Bear and long term research should be necessary.

  • The purpose of this study was to survey basic data for management of elderly day care centers. In this study, occupation, leisure life, and food, clothing and habituation, as well as social relationship, health state and behavior, and general characteristics of subjects were examined to identify the factors affecting their cognition, need and preference of the day care centers. The subjects of this study were 392 elderly, aged 60 years or over, living in Gangnung and neighboring districts. Data were collected by educated interviewers from November 4 through November 22, 2002. The subjects were interviewed face to face, one for one after the interviewee's agreements on the survey. The collected data were analysed with logistic regression analysis by SAS (statistical analysis system). Logistic regression analysis was done to identify affecting factors for cognition, need and preference of the elderly day care centers. The major findings are as follows: 1. The factors affecting cognition for the day care centers were analysed. The subjects with an occupation and a lower satisfaction level of living environment and friendship, who were economically secure enough to manage a sudden accident, showed a higher level of cognition of the day care centers. The subjects with a higher level of mental health state and a lower level of IADL also showed a higher level of cognition. On the general characteristics younger female subjects showed a higher level of cognition. 2. The subjects with a lower level of perceived economic condition who did not own their housing and were not economically safe enough to manage a sudden accident, had showed a higher level of need for the day care centers. It showed that the subjects with a high level of mental health state, a bad eye sight and dental condition, a good perceived health condition, and a lower level of IADL, needed the centers. 3. The subjects who had an occupation, however, not capable of making their own daily expenses, and a low occupation satisfaction level, and who did not own their housing, and were economically poor not enough to manage a sudden accident, showed a higher preference for the day care centers. The subjects with higher levels of friendship satisfaction and perceived health condition, not living with their spouse, and a higher education level, showed a higher preference for the centers. In conclusion, the common factors affecting their cognition, need and preference of the day care centers were occupation, economic security enough to manage accidents, and friendship satisfaction level. Especially, the subjects who had an occupation, however, not economically secure enough to manage accidents, and who did not live in their own housing with a good perceived health condition, showed high levels of need and preference for the day care centers. These results can be used as basic data to develop the efficient elderly day care centers, thus contribute to the elderly welfare in a local community.

  • In order to protect Rescue 119 workers exposed on the spot from potential infection, this study identified their awareness and practices of infection control so that it could help preventing them from infection and also provide basic materials necessary for pre-hospital infection control. This study applied questionnaire survey to total 215 Rescue 119 workers at fire stations in Jeonbuk province, Jeonnam province and Gwangju city from July 14 to Sept. 14, 2006 for the benefit of data collection. The questionnaire about possible associations between awareness and practices of infection control consisted of total 46 times across 6 categories such as washing hands during emergency activities ; fluid therapy and injection ; respirator maintenance; individual hygienics ; disinfectant supplies and equipments maintenance ; and control of infectious wastes. And collected data were processed using SPSS statistic program to analyze frequency and percentage, mean and standard deviation, Pearson's correlation coefficient, t-test and one-way ANOVA. As a result, this study came to the following conclusions : In terms of awareness about infection control, our respondents showed highest awareness about infectious waste control, and also showed highest level of practices in washing hands during emergency activities. Throughout all domains, awareness means were higher than practice means. In particular, infectious waste control was the domain of significant differences between awareness and practices. In terms of associations between awareness and individual characteristics, it was found that female rescue worker group and hospital/general hospital career group (before joining the Rescue 119) showed significantly higher awareness on statistic level. In regard to associations between individual characteristics and practices, it was found that female rescue worker group showed higher level of practices than male group on statistic level. This study also analyzed correlations between rescue workers' awareness and practice of infection control. As a result, it was found that the higher awareness was in correlations with the higher practices across all 6 domains including washing hands. In addition, the higher awareness of a questionnaire item was in significantly positive correlations with the higher practice of other items. However, our respondents showed high awareness about anti-infection, but low practices in reality. This indicates necessity of devising possible solutions to improve the practices as much as awareness. Especially, it was noted that major reasons for insufficient practices of infection control guideline come from unhabituated practices and lack of supports for infection-preventing supplies and protective device (mask, etc). Hence, it is necessary to provide more infection-preventing supplies for local rescue workers sufficiently, in parallel with steady habituation of infection control. Furthermore, it is required to manage and study infection control policies even at pre-hospital step in efforts for effective infection control, education and activities.
