While the average age of population increases, so as the number elderly workers employed in the private security in Korea. However, not many studies have examined the issues related to elderly security guards so far, especially regarding the experience of workplace violence victimization even though they are quite vulnerable. The current study surveyed elderly private security guards across the nation in an attempt to ask about their workplace violence victimization experience, including both physical and verbal ones. The researchers investigated if victimization experiences affect the elderly security guards' perception of occupational stress. The result indicated that the respondents experienced verbal violence more than physical violence, and perpetrators were usually customers, not their supervisor or coworkers. In addition, those who experienced verbal violence in the workplace, perceived a higher level of occupational stress. The experience of physical violence did not make a significant impact. Policies are discussed in order to decrease workplace violence towards elderly security guards.

The supply chain security programs are designed to prevent terrorist attacks on world transit system, and to help protect the passengers and workers who use these systems on a daily basis. as evidenced by the train bombings in London and Madrid in recent years, the threats to America's transit systems are real. After 9 11 terrors in 2001, security problem is appearing to every nations and international organizations main pending issue than any problem and various countermeasure is prepared. Security is the major issue in international trade, with significant potential costs and economic impact. So, We need to ensure that supply chain security does not become a new non-tariffs barrier. The aim of this study is to examine the international maritime and aviation law on the supply chain security. Also I review the supply chain security in U.S. and other countries.

Background: In modern society, depression is serious issue that causes socioeconomic and family burden. To decrease the incidence of depression, risk factors should be identified and managed. Among many risk factors for depression, this study examined socioeconomic risk factors for depression. Methods: We utilized first (2006), second (2008), and third (2010)-wave data from the Korean Longitudinal Study of Aging (KLoSA). Depressive symptom was measured with the 10-item Center for Epidemiological Studies Depression Scale, Short Form (CES-D-10) in the survey in 2008 and 2010. Three risk factors including job security, employment type and monthly income were measured in the survey in 2006. The association between risk factors and depressive symptom was analyzed by Cox proportional-hazard model. Results: We analyzed data from 1,105 workers and hazard ratios (HRs) for 3 risk factors were significant entirely. In addition, regular worker with high income group is the most vulnerable group of poor job insecurity on depression among male workers (HR: 1.73; 95% confidence interval [CI]: 1.07-2.81). Finally, HRs for 7 groups who had at least 1 risk factor had higher HRs compared to groups who had no risk factors after stratifying 3 risk factors. In the analysis, significantly vulnerable groups were total 5 groups and the group who had highest HR was temporary/daily workers with poor job security (HR: 2.51; 95% CI: 1.36-4.64). The results concerning women, regardless of job type, were non-significant. Conclusions: This study presented one or more risk factors among poor job security, low income, temporary/daily employment type increase hazard for depressive symptom in 2 or 4 years after the exposure. These results inform policy to screen for and protect against the risk of depression in vulnerable groups.

Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

This study was conducted to investigate the effect of strategic human resource management on job stress and occupational commitment of security workers. A sample of 188 persons was extracted using the SPSS 18.0 program as a significant sampling method for the security worker. Frequency analysis, correlation analysis, and multiple regression analysis were conducted according to the purpose of the data, and the following conclusions were drawn. First, strategic human resource management has a significant effect on job stress. Second, strategic human resource management has a significant impact on occupation. Third, job stress had a significant effect on occupation commitment. That is, two factors of strategic human resource management and job stress play a decisive role in occupation commitment, and job stress plays an important role as a parameter. In conclusion, if we select the factors of strategic human resource management needed for each organization and develop new methods and competitiveness, it will be very helpful for qualitative growth of security industry.

The Security Industry has dynamic working conditions. So this study intends to find the advisable direction for the reduction of accidents. To achieve the aim, the investigation of documents and the examinations of actual proofs have been done to figure the theoretical background and to see the basic knowledge of security industry. The questionnaire was composed of two question sheets to search real data and actual proofs, with making targets of pure security organization and personnel. The one consists of 9 questions to find the scale and extent of security organizations and the population and character of security personnel, and the other 25 questions in 3 major areas to analyze the causes, the frequency rates, the factors, and the condition of accidents. The period of survey was July 15th to October 15th in 1997 by mail/telephone/interview. The questionnaires were efficiently returned from 102 different organizations including the public security groups of Seoul Metropolitan Police Bureau and so on, with the information of 8,222 persons having worked for Korean Security Industry in 1996. So being based on the reality, some meaningful facts were found, and were compared with the national statistics of the Government. This study is made up of 5 chapters : in the 1st chapter the motivation, the object, the method, the direction and the limitation of the approach were presented ,in the 2nd chapter the theoretical background were inferred ; in the 3rd chapter the collected data of accidents in Korean Security Industry were analyzed and explained on the base of the questionnaires , in the 4th chapter the advisable facts connected with preventing accidents were mentioned ; in the last the conclusion were stated. With the replies of 102 different organizations including the information of 8,222 persons in 1996, the main facts found or analyzed through this study are as follows. Firstly, accident is an unpredictable and occasional event. It occurs to man and/or thing, but the frequency rate of accidents in Korean Government and other Institutes has been calculated and evaluated only in the point of the accident related with man. Secondly, the factors of accidents are firstly relevant to the way preventing accidents in Security Industry in Korea. However the frequency rate is academically calculated and evaluated by at once man(population) and hour(time). But the Government has done the rate only by man(population). This can be improper and inaccurate rates. Thirdly, the confused concept of security is used in Korean Government, academic society, corporation and so on. Therefore the detailed formation of the concept is needed for the development of Security Industry in Korea. Fourthly, security organizations can be classified into 'public security(public law enforcement)' and 'private security' according to its identification, and furthermore 'private security' can be divided into 'facilities-guard service', 'body-guard service', and 'patrol service' according to its major role. Fifthly, in the viewpoint of the number of both organization and population,'facilities-guard service' is centered in Korean 'private security'. According to the analyzed results of the questionnaires in this study, the frequency rate of accidents of Korean Security Industry is 0.43(%) totally in 1996 : 'facilities-guard service' 0.54(%), 'body-guard service' 0.12(%), and 'patrol service' 0.21(%) in 'private security', and 'public security' 0.20(%). With regard to the accident frequency rate of organization and population, 'facilities-guard service' is the highest. The accident frequency rate of population in 'facilities-guard service' organization ranges dispersively from 0.20(%) to 11.11(%). Sixthly, the accidented rate of workers having serviced for under one year is 57.6(%). This can mean that the main factor of accidents in Korean Security Industry is the lack of role-understanding and training/education. And another factor can be found on the time of accident occurrence. Many accidents have been occurred on the relaxed points like as just after lunch and morning rush-hour. Lastly, the major advisable facts related to preventing accidents are as follows : The workers who are over fifty years old in 'facilities-guard service' organization need to be educated for preventing accidents ; It is desirable that the training and education to prevent accidents should be practiced in the time of pre-service ; As the style of accidents and the age of the accidented are not same according to major service area('public security' and 'private security' : 'facilities-guard service', 'body-guard service', and 'patrol service'), the plans to prevent accidents must be different and various. However fracture and bruise are general accidents in Korean Security Industry ; Workers must care about traffic accident and violent fall ; It seems that the grouped working with other two persons will reduce accident occurrence possibility rather than individually single working.

This article aims to analyze some conditions for the reinforcing social security rights of atypical construction workers, and their socio-economical effects, and furthermore, to explore political measures for compliance with obligation of the four basic social insurances. Although the construction industry is one of the pivotal industry sectors, which contributes to the economic development, it is a typical industry sector, half of whose manpower is atypical and irregular. This kind of reality results especially from its own sectoral features and employment structure. We will argue that our society needs political measures for compliance with obligation of the basic social insurances for the construction workers, and it would help the reinforcing social safety net of the precarious construction workers, and furthermore enhancing competition in the construction industry. For this purpose, we will suggest concrete conditions for compliance with obligation of the basic social insurances and prove its positive socio-economic effects. In the end, we will propose some detailed measures like direct construction, introduction of the prevailing wage, etc. for this politic approach.

Workers' anomalous trajectories allow us to detect emergency situations in the workplace, such as accidents of workers, security threats, and fire. In this work, we develop a scheme to detect abnormal trajectories of workers using the edit distance on real sequence (EDR) and density method. Our anomaly detection scheme consists of two phases: offline phase and online phase. In the offline phase, we design a method to determine the algorithm parameters: distance threshold and density threshold using accumulated trajectories. In the online phase, an input trajectory is detected as normal or abnormal. To achieve this objective, neighbor density of the input trajectory is calculated using the distance threshold. Then, the input trajectory is marked as an anomaly if its density is less than the density threshold. We also evaluate performance of the proposed scheme based on the MIT Badge dataset in this work. The experimental results show that over 80 % of anomalous trajectories are detected with a precision of about 70 %, and F1-score achieves 74.68 %.

Objectives : A survey was conducted to investigate oral health belief and education awareness of oral health of workers in the workplace and to obtain the basic data necessary to promote their oral health and design an oral health education program. Methods : This study conducted a self-administered survey. Results : The following conclusion was made. For oral health beliefs based on the type of work that the workers did, workers in production and technical services had more benefits than those in other fields(security, guard, etc.), and workers on night duty had more oral health hygiene problems than that of regular day-time workers. The longer the period of service was, the more sensitive and serious the workers were and the less beneficial the work was; workers working for eight hours or less had higher levels of importance than those working for ten hours. They were well aware of the need for oral health education but were less aware of the need for an oral health room. Conclusions : It is necessary to emphasize oral health beliefs when developing an oral health education program that promotes oral health for workers in the workplace. If an oral health education program attempts to reflect the concerns of workers in the workplace and provides preferred contents and methods on oral health education, the program is expected to promote the active and positive participation of the workers.
