Objectives: This study aims to establish the concept of "dental assistance" within the dental field and to identify the scope of dental assistance, which can be utilized in order to distinguish the scope of work between jobs. Methods: The literature on dental hygienist work and dental assistance was reviewed, and the laws and precedents related to dental assistance were examined. Results: The criteria for judging the legitimacy of dental assistance included the following: whether the performance was conducted under the guidance and supervision of a doctor; whether there was a possibility of an aftereffect or side effects of the procedure; whether education was conducted within the curriculum; and whether it was evaluated in the national licensing examination. In addition, the work of the assistant in dental surgery and treatment is judged comprehensively by considering the type of dental surgery and treatment, invasive degree, necessity of expertise, and work proficiency of the dental hygienist. Therefore, it is suggested that dental hygienists may be of assistance for dental treatment/surgery because they meet the requirements of dental professionals, such as dental hygiene curriculum, national licensing examination, duties in the field of dentistry, and work proficiency. Conclusions: Dental assistance (including assistance in dental surgery) for dental treatment, dental/medical history taking, taking vital signs, and blood glucose monitoring should be permitted within the realm of dental hygienist work. Therefore, the actual expertise of dental hygienists should be reflected legally and the work of dental hygienists should be realized.

Objectives: The purpose of the study is to investigate the related factors to dental care utilization, oral health behaviors, and oral health status in immigrant workers in Korea. Methods: The subjects were 504 foreign immigrant male workers over 20 years old who visited Daegu labor consultation center for oral health survey and oral examination. The questionnaire included 5 questions of socioeconomic characteristics, 8 questions of oral health practice behavior, 6 questions of dental clinic visit, 8 questions of social relations and Korean language proficiency. The question for health behavior was measure by body mass index(BMI). Social relations and Korean language proficiency instrument was modified by Seol from "Family welfare survey in Korean international marriage" and scored by Liker 5 scale. Results: The oral health examination of the immigrant workers was as follows: decayed teeth - 76.6%, filling teeth - 27.4%, missing teeth - 69.8%, dental caries experience above five or more - 60.2%, periodontal pocket tissues - 58.9%. Simplified Oral Hygiene Index was very poor and accounted for 49.0%. Dental care utilization experience was closely associated with social relation indexes including attendance in family events, household stuff help, financial help and counseling for hard work(p<0.01). Dental care utilization experience proportionally increased with proficiency in Korean literacy including speaking, listening, and writing abilities of Korean language(p<0.01). Conclusions: In order to improve the oral health condition of the immigrant workers, it is important to provide social network, Korean language proficiency support, and health insurance coverage through economic burden reduction by the Korean government.

Objectives: The study investigated health professionals working in the metropolitan area and Jeolla-bukdo, South Korea, from April 30 to May 17, 2017 to understand their views on the issue of including dental hygienists in the scope of medical personnel of South Korea. Methods:A total of 270 surveys were analyzed in this study. The survey consists of 5 questions on general issues; 10 on the awareness of present work of dental hygienist; and 1 on opposition or approval about including dental hygienist in medical personnel. The collected data were analyzed using SPSS for Windows 18.0, as well as frequency analysis, cross analysis and logistic regression analysis. Statistical significance level (${\alpha}$) is 0.05. Results: 1. Broken down by gender, male subjects showed more oppositions against including dental hygienists in the category of medical personnel while female subjects showed more favorable opinions (p<0.05). In terms of academic background, those who had graduated from graduate school or higher showed a higher propensity for opposition while those who had graduated from a 3-year college showed a higher tendency for approval on the idea (p<0.05), In terms of occupational type, health professionals showed more opposing views whereas medical technologists showed more approvals than others (p<0.001). 2. With respect to the awareness of work specialty and proficiency of dental hygienist according to general characteristics, the higher the age, the higher the awareness level was. In terms of the occupational type, medical technologists were found to have higher awareness level than health professionals (p<0.001). 3. With respect to the relationship between general characteristics and view on including dental hygienists in medical personnel, the occupational type of health professional was found to have 6.33 times more oppositions than medical technologists. When the awareness level on proficiency of dental hygienist was low, opposition was 6.52 times more frequent (p<0.05). Conclusions: Based on the findings above, the inclusion of dental hygienists in medical personnel seems necessary in properly establishing the specialty and role of dental hygienist in the dentist medical environment of the country in order to enhance national oral health related preventive dental service and expand the demand. To this end, it is necessary to provide nationwide promotion, work to change the awareness of health professionals in other occupational types, and facilitate public promotion for legal ground establishment.

Under the STCW Convention, marine engineers are required to have a satisfactory level of maritime English proficiency so that they can successfully perform their duties on board or maintain and operate the various equipment and facilities installed in the ship. More specifically, the importance of the engineers' written communication skills has been highlighted since their documents (for instance, post-work records, legal, and/or internal reports) have a significant legal impact in the event of a marine casualty or maritime crime. To suggest the necessity of developing standard engineering logbook phrases (SELP), therefore, this paper will closely analyse three-month authentic marine engineers' work records written by Korean officers. From the analysis, the problems and errors in the logbook will be analysed, and considerations to be taken into account in the development of SELP will be illustrated. Finally, the future actions for this standardised written communication for the logbook entry will be sought.

In 1992, the quality control program was introduced in Republic of Korea to improve the reliability of the work environment monitoring, which was introduced in the 1980s. The commission entrusted by the Ministry of Employment and Labor, the Occupational Safety and Health Research Institute has conducted the program for industrial hygiene laboratories including designated monitoring institutions and spontaneously participating agencies. The number of institutions that participated in the program has increased from 30 to 161. The initial conformance ratio in the participants was 43% (organic solvents) and 52% (metals). Thereafter, the conformance ratio increased rapidly and it has remained in a stable state at more than 89% since 1996. As subject materials, 13 kinds of organic solvents and 7 kinds of metals were used. To improve the capability of measurement and analysis of private institutions, educational courses were conducted annually. An assessment at the actual sites of participants was additionally introduced into the program in 2013. Thus, the program turned into a system that administrates the overall process of participants. For the future, the scope of target materials will be extended through additional items. Thus, the reliability of the results of the work environment monitoring is expected to increase accordingly.

Objectives: The objectives of this study were to develop a quality control protocol of inorganic acids using ion chromatograph and to evaluate analytical proficiency of the legally designated agencies. Methods: This study prepared inorganic acid samples by injecting three anion certified solutions (chloride, nitrate, and sulfate) on the quartz filters. To investigate the storage stability and concentration consistency of the samples, 240 samples for each anion were tested at weeks 0, 2, 4, 8, 12, and 16 while storing at 4℃ and 25℃. To evaluate analytical proficiency, two separate testings were administrated for six skilled analysts and 46 analysts affiliated with legally designated agencies. Results: Average recoveries of the three ions after 16 weeks of storage were fairly high (over 95%). In addition, average recoveries (chloride = 97%, nitrate = 96%, and sulfate = 103%) after 16 weeks of storage at low temperate were relatively higher than those (94%, 93%, and 98%) at room temperature. The coefficients of variation (CV) for the three ions were less than 5% except for the sulfate sample at 5.56 ㎍ (CV = 12.4%). The average ratios of the concentration values analyzed by the legally designated agencies to the injected concentrations were close to 1. However, their CVs were relatively greater (chloride ≤ 49%, nitrate ≤ 14%, and sulfate ≤ 28%), which implies a need for quality control. Conclusions: The quality control protocol used in this study for the three inorganic acids can be utilized in the quality control for ion chromatography.

This Paper addresses what amount of whole-body vibration is exposed to Korean pilots of UH60 helicopters during their mission flight. To measure the expose4 whole-body vibration, the 12-axis whole-body vibration measurement system was used. It enables the direct measurement of whole-body vibration exposed from the body contact area consisting of the feet, hip and back. The measured 12-axis vibration signals were used to evaluate the vibration comfort level experienced by the pilots of UH60 helicopters. The evaluated vibration comfort level is found to be closeto 0.74-0.79m/s, which is equivalent to the semantic scale of 'fairly uncomfortable'. To assess the health effects of whole-body vibration exposed to Korean pilots of UH60 helicopters during their mission flight, the rms-based and VDV(vibration dose value)-based evaluation schemes, recommended by ISO 2631-1:1977, were exploited in this work. The evaluated results indicate that Korean pilots cannot avoid the fatigue-decreased proficiency limit after two-hour continuous flight. The whole-body vibration level exposed from the UH60 helicopters during continuous 10-hours mission flight is found to reach to the vibration exposure limit.
