  • Based on recent dramatic increases in foodborne outbreaks in restaurants, self-managed sanitation systems are now recommended to control contributing risk factors. This study aimed to improve sanitation management practices in restaurants and had two objectives. First, we tried to develop a self-managed sanitation check-list, including risk factors contributing to foodborne illness and Korean food hygiene regulation articles. We also tried to evaluate current sanitation management practices in restaurants according to operation and restaurant type. Thirty restaurants were evaluated by on-the-spot inspectors using an auditing tool consisting of four dimensions, seventeen categories, and forty-one items. Total compliance rate categorized by operation type significantly differed between chain restaurants and self-managed restaurants, with values of 85.5% and 51.6%, respectively. Therefore, self-managed restaurants, which showed the lowest compliance rate of below 30.0%, need more strict control to improve current unsanitary management practices, specifically relating to 'sterilization of knives, chopping boards, and wiping cloths', 'sanitation training', 'not allowing access into the kitchen to outsiders', 'handling of food or utensils on shelves at a 15 cm distance away from floor', 'prevention of cross-contamination of cooked foods or vegetables', and 'records of kitchen access or inspection'. Thus, an effective food sanitation system is essential and should be implemented to improve the existing sanitary conditions in restaurants. However, the most important factor to achieving food sanitation management objectives is food handlers' self-motivation.

  • Purpose: To update the epidemiologic information of hepatobiliary diseases in pediatric inpatients using cross-sectional survey data throughout the Republic of Korea. Methods: Nationwide cross-sectional survey was obtained from the 85 residency training hospitals in Korea to gather the final diagnosis on discharge. The surveyed periods were from 2004 to 2006. All the reports regarding the diagnosis were based on ICD-10 system. In this study, we focused on hepatobiliary diseases. Results: A total of 826,896 cases with discharge data were collected, of which 4,151 (5.0%) hepatobiliary cases were identified; 2,385 cases (57.4%) of hepatobiliary disease were hepatitis, which was the most common hepatobiliary disease. Other diseases included congenital hepatobiliary diseases (524 cases [12.6%]) and biliary diseases (315 cases [7.6%]). The prevalence of hepatobiliary disease according to age differed. Biliary atresia was the most common hepatobiliary disease in the neonatal period, whereas the prevalence of hepatitis increased in adolescents. The total number of hepatobiliary operations was 416 cases. With the comparison of annual data, there was no definite difference in the total number of hepatobiliary cases. The average duration of hospital stay appeared to decrease gradually. Conclusion: In this study, we have summarized the recent epidemiology of hepatobiliary disorders in Korean children based on discharge data. Hepatobiliary disorders in pediatric inpatient units consisted of diverse disorders with a low prevalence, so multi-center approaches should be considered to enhance the clinical and public health outcomes. To improve this nationwide survey, a new data collecting system should be developed.

  • Sometimes the dentists encounter a child who can not be treated with traditional behavior management techniques (for example, reward, restraint, Tell-Show-Do, familialization). In such a case, the dentists use sedation technique. Recently, in Korea, the use of sedation by pediatric dentists is increased. But, the guideline and survey of sedation is very insufficient. Now, we need a survey of sedation practice in Korea. We carried out research on the actual condition about sedation with a questionaire to pediatric dentists in Korea. Followings are the conclusions 1. Sixty six percent of pediatric dentists use sedative agents in their practice. In this study, using sedation shows an increase as compared with the past. 2. Determinative factors of using sedation were orderly behavior management, number of visiting, guidian's opinion, amount of treatment, general condition. 3. Distribution of ages in patients sedated with agents was orderly 3 years, 4-5 years, under 2 years, 6-10 years, more than 10 years. 4. Particular sedative drugs were chloral hydrate 60-70mg/kg, hydroxyzine 10-40mg/kg(25mg/kg), and oral route was the most favorable route. 5. Observation of skin and nail color, pulse oximeter were the most frequently utillized monitoring method during sedation. 6. Only fifty six percent of pediatric dentists complete the cardiopulmonary resuscitation course.

  • This paper examines a social and cultural history of horror films through the keyword "technology", focusing on The Spark of Fear: Technology, Society and the Horror Film (2015) written by Brian N. Duchaney. Science fiction film is closely connected with technology in film genres. On the other hand, horror films have been explained in terms of nature/supernatural. In this regard, The Spark of Fear, which accounts for horror film history as (re)actions to the development of technology, is remarkable. Early horror films which were produced under the influence of gothic novels reflected the fear of technology that had been caused by industrial capitalism. For example, in the film Frankenstein (1931), an angry crowd of people lynch the "monster", the creature of technology. This is the action which is aroused by the fear of technology. Furthermore, this mob behavior is suggestive of an uprising of people who have been alienated by industrial capitalism during the Great Depression. In science fiction horror films, which appeared in the post-war boom, the "other" that manifests as aliens is the entity that destroys the value of prosperity during post-war America. While this prosperity is closely related to the life of the middle class in accordance with the suburbanization, the people live conformist lives under the mantle of technologies such as the TV, refrigerator, etc. In the age of the Vietnam War, horror films demonize children, the counter-culture generation against a backdrop of the house that is the place of isolation and confinement. In this place, horror arises from the absolute absence of technology. While media such as videos, internet, and smartphones have reinforced interconnectedness with the outside world since the 1980s, it became another outside influence that we cannot control. "Found-footage" and "torture porn" which were rife in post-9/11 horror films show that the technologies of voyeurism/surveillance and exposure/exhibitionism are near to saturation. In this way, The Spark of Fear provides an opportune insight into the present day in which the expectation and fear of the progress of technology are increasingly becoming inseparable from our daily lives.

  • Though a valve is a very important part in a system to control properly, it has potential failure caused by gap from valve stem to ball connection, and abrasion, crack, fixation causing operational trouble and accidents. 64% of the valve failure in the real case was the failure of airtightness and most accidents of leakage and explosion were occurred while fixing the failure. While there are no proper safety manual, maintenance procedure and regulation for industrial valves excluding safety valve, safety management for the valves is left to the discretion of the maintenance company. Strict maintenance that removes hazards and emergency response procedure are required to prevent and reduce the loss of accident. This study suggests safety enhancement measures through valve monitoring by investigating the status of use of valve and current maintenance. Enhancement of gas safety management can be acquired by a monitoring system that provides diagnosis for valve status, monitoring real-time gas leakage, management of entire cycle lifetime that can reduce maintenance cost.

  • Electric vehicle performance is very dependent on traction batteries. For developing the electric vehicles with high performance and good reliability, the traction batteries have to be managed to get maximum performance under various operating conditions. The enhancement of the battery performance can be accomplished by implementing battery management system (BMS) that plays important roles of optimizing the control mechanism of charge and discharge of the batteries as well as monitoring battery status. In this study the battery management system has been developed for maximizing the use of Ni/MH batteries in electric vehicle. This system provides several tasks: the control of charging and discharging, overcharge and over-discharge protection, the calculation and display of state of charge, safety and thermal management. The BMS was installed in and tested using the DEV5-5 electric vehicle developed by Daewoo Motor Co. and Institute for Advanced Engineering in Korea. The 18 modules of Panasonic Ni/MH battery, 12 V-95 Ah, were used in the DEV5-5. The high accuracy within the range of $3\%$ and the good reliability were shown in the test results. The BMS can also improve the performance and cycle life of Ni/MH battery pack as well as the reliability and safety of the electric vehicles (EV).

  • It has been widely accepted that the environment is an important determining factor of human health. Appreciating the relationship between the environment and human health, Korean government has begun to deal with issues of environmental health. The government proclaimed the year of 2006 to be the first year of Environmental Health and established "The Environmental Health Plan for the next 10 Year". In order to achieve the goals in the plan, there are necessary considerations such as support systems for environment health related research, investigation, law, institution, administration, and so forth. This study suggests basic principles required to establish a legal regime of environmental health which is to implement the environmental health policies in Korea. Several cases of foreign legislation and policy relevant to environmental health are reviewed. Also, existing related legal system in Korea are analysed considering legal and institutional elements for establishing an effective environmental health policy. The main purpose of amending legal system related environmental health is to protect both public health and the soundness of ecosystem. To reach the goals effectively, the concept of 'environmental health' should be clearly established and presented. In addition, an advanced prevention system, including investigation and prevention of the cause of environmental diseases and risk assessment based on the precautionary principle, are substantial in the environmental health legislation. Also the environmental health law should guarantee public participation in decision making as well as the first consideration of susceptible or vulnerable population. This study concludes that the expected legislation related to environmental health should be a nonnative instrument not only for integrating each environmental protection scheme but also for establishing and implementing the policy.

  • Journal bearings in the rotating machineries are vulnerable to the contamination or the insufficient supply of lubricating oil, which is likely to be the cause of unexpected shutdown or malfunction of these systems. Various destructive and nondestructive testing methods had been used for the reduction of maintenance cost and the operational safety problems due to the accidents related to bearing damages. In this experimental approach, acoustic emission monitoring is employed to the detection of incipient failure caused by intervention of foreign particles most probable in the journal bearing systems. Experimental schedules for the intervention of foreign particles was composed to be more quantitative and systematic than last study in consideration of minimum oil film thickness and particle size. The experiment was conducted under such designed conditions as inserting alumina particles to the lubrication layer in the simulated journal bearing system. Several parameters such as AE rms level, waveform, AE energy distribution and other AE event parameters are used for analysis and characterization of damage source. The results showed that the history of damage was well correlated with the changes of AE rms level and the type of damage source signal can be verified using other informations such as waveform, distributions of AE parameters etc.
