Objectives: A field survey was conducted in a hog-raising industry in order to help develop personal protective equipment for workers which would secure the safety and the health of these workers. The attempt by this study will help enhance safety in the livestock industry and contribute to the advancement of the industry. Method: The study first selected a total of 111 workers from the hog-raising industry as research participants and designed a survey with questions on general characteristics, indoor and outdoor working environments, how the workers would in practice wear or purchase the working clothes, what needs to be improved in these new working clothes, how much the workers would be likely to accept the working clothes and protective equipment, and lastly, conditions of the communicable disease control overgarment. The collected data underwent frequency analysis and cross analysis with SPSS 21.0. Result: The research targets' average age was 50 years. Work efficiency by environmental factor was normal, but all age groups had experience of accidents (79.3%). Major wounded parts were under elbow and under knee. Protective equipment most commonly worn was helmet (83.4%), gloves (98.2%) and boots (99.1%), and satisfaction with them was normal at 3.41. Working clothing most commonly worn was old clothing (31.8%) and everyday wear (17.6%) and satisfaction with it was low. Considering the improvement of working clothing, they required attached pouches, elasticity and deodorization. The acceptability of improved working clothing was high at 69.2%. Conclusion: After problems have been addressed in relevant future research, what has been learned from the concerned study will be referred to as a useful basic reference when the relevant field works to develop high-quality working clothing and protective equipment for workers in the hog-raising industry.

This study was performed to evaluate tannin exposure by wooddusts for workers in furniture factories and to investigate the relationship between tannin exposure and sino-nasal cancer risk. In order to explore possible cytological changes leading to nasal cancer, we have examined 50 male furniture workers and 50 matched controls using brush cytology. The results we have obtained in this study were as follows: 1. The tannin contents of woods used in woodworking factories have been measured and varied from 0.43 to 8.72 mg tannic acid equivalent per gram wood, for reconstituted softwood and turpentine (Syncarpia glomuliferia) respectively. 2. Airborne tannins in wooddusts were also determined by area and personal exposure. The values of mean exposures for both methods are ranged from 3.1 to $5.0{\mu}g/m^3$ and from 4.6 to $14.5{\mu}g/m^3$ in furniture manufactures. 3. Over nasal cytology scores 2, the scores of study group were slightly more than control group and this kind of metaplasias seemed to be occurred over $2mg/m^3$ wooddust and $6{\mu}g/m^3$ tannin exposure. Keratinising squamous metaplasia was investigated at nasal cytology score 3 and $10{\mu}g/m^3$ tannin exposure. The nasal cytology score 4 was seemed to be atypical squamous metaplasia. 4. To find out contributing factors to nasal cytology change, odds ratio that is one of fundmental biostatistics was applied. Actually the relationship between wooddust, tannin concentration and metaplasia were not meaningful, but the relationship between working experence more than 15 years and metaplasia was calculated as 1.83. This reveals that significant clinical abnormalities could be influenced from the years of woodworking experiences. However further research is required to evaluate the significance of the data, for the purposes of sino-nasal risk assessment, standard setting to prevent nasal cancer occurrences and possibility of changing workplace.

The purpose of this study is to investigate the structural relationships among frontline hotel employees' core-self evaluations (self-esteem, generalized self-evaluations, locus of control, and emotional stability) as personal resources, customer verbal aggression as a job stressor, and turnover intention as a job outcome. Data were gathered from a sample of frontline employees of 10 five-star hotels in Busan via self-administered questionnaires. A total number of 405 questionnaires were utilized. This study used structural equation modeling to verify the research model and hypotheses. As hypothesized, the results demonstrated that core-self evaluations reduced customer verbal aggression and turnover intention, and customer verbal aggression amplified turnover intention. Finally, practical implications were discussed in detail and limitations of the study and future research directions were also suggested.

As many people use internet through the various programs of PC and mobile devices, the possibility of private data leak is increasing. A program should be used after checking security of information flow. Security analysis of information flow is a method that analyzes security of information flow in program. If the information flow is secure, there is no leakage of personal information. If the information flow not secure, there may be a leakage of personal information. This paper proposes a method of analyzing information flow that facilitates SAT solver. The method translates a program that includes variables where security level is set into propositional formula representing control and information flow. The satisfiability of the formula translated is determined by using SAT solver. The security of program is represented through the result. Counter-example is generated if the program is not secure.

Given social problems of service addiction such as mobile messenger services(MMSs), many studies on service management and information systems have examined the negative outcomes of service addiction. MMS addiction significantly influences user's health and academic performance. In this regard, this study investigated the effects of MMS addiction on user's health and academic performance problems. We posit personal traits and service features as key antecedents of MMS addiction. The research framework was tested by using survey data collected from 162 university students who have frequently used Kakaotalk. The analysis results found that MMS addiction significantly influences users' health and academic performance problems. The findings of this study indicate that self-esteem and self-control play an important role in generating MMS addiction. While attention significantly affects MMS addiction, social relationship formation and perceived enjoyment are not significantly associated with MMS addiction. The analysis results help MMS providers and government establish policies or guidelines to induce healthy MMS use.

The purpose of this study was to develop a "Family Play Therapy Program" using puppets to decrease attachment problems for families with children having attachment problems and to examine its effectiveness. The participants were an experimental group of 16 individuals(8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers) and a control group of 16 individuals (8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers). The experimental group was treated through the Family Play Therapy Program, which involved the use of puppets and was held for twelve sessions twice a week. The changes in the participants were measured in order to examine the effects of the program. The researcher measured children's emotional and behavioral expression(TBP), the mothers' sense of self(Self-Differentiation Scale), personal relationships(ECR-R), and the perception of family functions(ICPS-FFS) both before and after the FPT program and compared their differences. The MIM Rating Scale and Marschak Behavior Rating Scale were administered to examine the interactions between mothers and children, and 1:1 interviews were also conducted. The data thus gathered were used for non-parametric analysis(Mann-Whitney U test and Wilcoxon rank sum test)using SPSS WIN 17.0. The results of this study were as follows: First, the program had a positive effect on children's emotional expression. After the problem were over, negative emotional and behavioral expression in the experimental group decreased. Second, the program had a positive effect on mothers' self-differentiation and personal relationships. Third, the program had a positive effect on changes in the interaction behaviors between the mother and child. Fourth, the program had a partially positive effect on the responses from their group developmental stages, especially on the subscale of both a program for the reinforcement of mothers' emotions and family play program utilizing puppets.

BACKGROUND/OBJECTIVES: Many adolescents in developing countries skip breakfast. Innovative nutrition education (NE) strategies are needed to enhance knowledge and skills related to the breakfasts of adolescents in a low socioeconomic setting. The objective was to evaluate short- and long-term effects of a multi-strategy, school-based NE intervention on adolescents' breakfast-related personal influences and behaviors. SUBJECTS/METHODS: An intervention study with a cluster randomized controlled trial design was conducted in 4 senior high schools in Makassar, Indonesia. The multi-strategy NE intervention was delivered for 3 months. Data were collected using a self-administered questionnaire and a 3-day breakfast recall (face-to-face interview). Wilcoxon, McNemar, and Mann-Whitney tests were used to determine intra- and intergroup differences. RESULTS: Unlike knowledge, improvement was observed in attitude and self-efficacy scores in the intervention groups (IGs) (P < 0.01); however, no significant changes were observed in the control group (CG). More students showed improved motivation in the IG than in the CG (P > 0.05). Changes in breakfast frequency and macronutrient intake from breakfast were greater in the IG than in the CG (P < 0.05). CONCLUSIONS: A multi-strategy NE intervention is effective in producing positive changes in breakfast-related attitude, self-efficacy, and motivation of adolescents from a low-middle socioeconomic setting. The intervention improved breakfast frequency and nutrient intake. This intervention has promise for sustaining the observed changes over the long-term.

The incredible progress of information and communication technology has allowed various information and communication services to emerge in the Web environment. Such a service is initiated when the user provides his/her personal information to the service provider and is then given an identifier and authentication data. A series of the processes is inconvenient as it requires authentication by the service provider each time that the user requests the service. Furthermore, as the user subscribes to more services, the volume of ID and authentication information increases. This compels the users to use an ID that is easy to remember or to register the same ID over and over, increasing the risk of ID hacking. It is clear that such threats will become more serious as our lives become more dependent upon the Internet and as the Internet service environment advances. With the introduction of different services, the need to efficiently manage ID has been raised. In this paper, a Internet Identity Management Service that enables the control of the flow of the user’s personal information, which is used and stored for the Internet service, is proposed from the user's perspective.

There has been significant research in security technology such as e-passport standards, as e-passports have been introduced internationally. E-passports combine the latest security technologies such as smart card, public key infrastructure, and biometric recognition, so that these technologies can prevent unauthorized copies and counterfeits. Biometric information stored in e-passports is the most sensitive personal information, and it is expected to bring the highest risk of damages in case of its forgery or duplication. The present e-passport standards cannot handle security features that verify whether its biometric information is copied or not. In this paper, we propose an e-passport security technology in which biometric watermarking is used to prevent the copy of biometric information in the e-passport. The proposed method, biometric watermarking, embeds the invisible date of acquisition into the original data during the e-passport issuing process so that the human visual system cannot perceive its invisibly watermarked information. Then the biometric sample, having its unauthorized copy, is retrieved at the moment of reading the e-passport from the issuing database. The previous e-passport security technology placed an emphasis on both access control readers and anti-cloning chip features, and it is expected that the proposed feature, copy protection of biometric information, will be demanded as the cases of biometric recognition to verify personal identity information has increased.

Purpose: This study aimed to describe clinical nurses' lived experiences of workplace verbal violence through qualitative research using descriptive phenomenology. Methods: Six female Korean nurses who had less than 5 years of clinical experience and had experienced verbal violence in the workplace within the past year participated in the study. Data were collected through one-on-one in-depth interviews with the participants and analyzed using Colaizzi's phenomenological method. Results: A total of 27 codes, eight themes, and four theme clusters were derived from the participants' statements. The four theme clusters of the clinical nurses' experiences of verbal violence in the workplace were as follows: "tip of the iceberg," "beyond me and my control," "fear and resignation," and "personal burden." The participants recognized that nurses experienced verbal violence daily, and that the causes of and responses to verbal violence were determined by external situational factors rather than nurses' individual problems. This suggests that nurses felt that they had no choice but to personally cope with verbal violence and bear the consequences due to systematic indifference and silence about verbal violence experienced by clinical nurses. Conclusion: The findings show that verbal violence was pervasive and unmerited, yet often endured at the cost of a personal burden to nurses. A clear definition of verbal violence and education for employees are needed, and a reporting system should be established to report all forms of violence regardless of the severity of the incident.
