  • Purpose: This study was conducted with a focus group interview that drew out experiences, limitations, and difficulties in the workplace according to the employment conditions of visiting nurses in the public health centers. Methods: A total of 12 visiting nurses are those working in the public sector in Seoul and Gyeonggi province who were willing to participate in the interview. Analysis categories and coding were divided into three categories: compensation system, occupational status, and opinions to improve their treatment. Using the content analysis method, the current working status and compensation system of visiting nurses were described. Results: The main themes derived from the significant statements of visiting nurses were 'Ten years of frozen salary system', 'Full-time workers of their own league', 'Excluded from performance benefits', 'Every visiting nurses are virtually precarious', 'Experience of exclusion and discrimination', and 'Reasons and barriers to be a full-time worker'. All of the visiting nurses working in the community insisted on having equal treatment for work of equal value. Visiting nurses in the public health sector wanted to be set to the same payment system and the fair allowance system as well. It is necessary to continuously seek solutions to the problems left in insisting on the civil service of visiting nurses. Conclusion: Visiting nurses who were working in a precarious job position felt job insecurity, and experienced discrimination, alienation, and exclusion. Legal and institutional reform is needed to improve the treatment of visiting nurses.

  • The purpose of using coolant in machining is both to increase a tool life and also to prevent product deformation and thus, stabilize the surface quality by lubricating and cooling the tool and the machining surface. However, a very small amount of cutting mist should be used because chlorine-based extreme pressure additives are used to generate environmental pollutants in the production process and cause occupational diseases of workers. In this study, medical titanium alloy (Ti-6Al-7Nb) was subjected to a processing experiment by selecting factors and levels affecting cutting power in the processing of the Aerosol Dry Lubrication (ADL) method using vegetable oil. The machining shape was a slot to sufficiently reflect the effect of the cutting depth. As for the measurement of cutting force, the trend of cutting characteristics was identified through complete factor analysis. The factors affecting the cutting force of ADL slot processing were identified using the reaction surface analysis method, and the characteristics of the cutting force according to the change in factor level were analyzed. As the cutting speed increased, the cutting force decreased and then increased again. The cutting force continued to increase as the feed speed increased. The increase in the cutting depth increased the cutting force more significantly than the increase in the cutting speed and the feed speed. Through the reaction surface analysis method, the regression equation for predicting cutting force was identified, and the optimal processing conditions were proposed. The cutting force was predicted from the secondary regression equation and compared with the experimental value.

  • In the recent era of the fourth industrial revolution, many industries aim to maximize the efficiency of products and services by introducing cutting-edge technologies such as artificial intelligence and big data. In this situation, organizational culture is changing a lot due to the influx of the MZ generation with strong individualistic tendencies and the decreased face-to-face communication between members. However, active communication with colleagues is still essential to maximize performance, and the margins created by simplifying work processes and automating processes must be used for creating work performance. This requires cooperation and commitment through the job immersion of members who have an active attitude. This study analyzed how the organization's autonomous work environment and trust among members, which are creative work performance conditions, affect job immersion using raw data from the Occupational Safety and Health Research Institute. As a result, it was found that both the organization's autonomous working environment and trust among members significantly effected the members' job immersion. in order to achieve productivity and value improvement in companies, efforts are needed to increase workers' job immersion by building an autonomous working environment and trust among members. The results of this study are expected to contribute significantly to the search for ways to increase workers' job commitment to improve organizational productivity.

  • Objectives: This study investigated the prevalence and characteristics of comorbid conditions in patients exposed to ionizing radiation and those who were involved in the Soviet-Afghan war. Methods: This study analyzed the frequency and spectrum of morbidity and comorbidity in patients over a long-term period (30-35 years) following exposure to ionizing radiation at the Semipalatinsk nuclear test site or the Chornobyl nuclear power plant, and among participants of the Soviet-Afghan war. A cohort study, both prospective and retrospective, was conducted on 675 patients who underwent comprehensive examinations. Results: Numerical data were analyzed using the Statistica 6 program. The results are presented as the mean±standard deviation, median, and interquartile range (25-75th percentiles). The statistical significance of between-group differences was assessed using the Student t-test and Pearson chi-square test. A p-value of less than 0.05 was considered statistically significant. We found a high prevalence of cardiovascular diseases, including hypertension (55.0%) and cardiac ischemia (32.9%); these rates exceeded the average for this age group in the general population. Conclusions: The cumulative impact of causal occupational, environmental, and ultra-high stress factors in the combat zone in participants of the Soviet-Afghan war, along with common conventional factors, contributed to the formation of a specific comorbidity structure. This necessitates a rational approach to identifying early predictors of cardiovascular events and central nervous system disorders, as well as pathognomonic clinical symptoms in this patient cohort. It also underscores the importance of selecting suitable methods and strategies for implementing treatment and prevention measures.

  • 한약은 오랫동안 사용하면서 경험적으로 안전성에 대한 검증이 이루어졌다고 생각하여 독성 문제에 관한 문제가 없는 것으로 판단되고 있다. 하지만, 최근 천연물의 성분들 중 변이원성, 염색체이상에 관한 문제점이 지적되어오고 있다. 특히 최근 임신중의 환경인자나, 약물복용에 따른 기형아 출산원인에 대한 연구가 행하여지고 있는데 임신 초기에 한약을 복용한 경우 기형아 발생률이 높았다는 보고가 있어 한약재의 임신중 사용의 안전성에 대한 과학적 조명이 필요한 실정이다. 임신과 분만에 관련된 한약재는 많이 보고되어 있고 실제로 환자에게 처방되고 있지만 이를 과학적으로 입증하고자 하는 연구는 많지 않았다. 따라서 본 실험은 임신유지, 성장 및 분만과 태아발생 및 그 영향과 관련된 한약재의 효능을 임신 랫드를 이용하여 간접적으로 확인하였다. 우선 임신 랫드를 임신 1일부터 20일까지 보생탕을 경구 투여하여 모체의 체중변화를 살펴보았다. 그리고 임신 20일에 부검하여 채혈을 하여 혈액분석을 하고 모체의 각 장기를 관찰하였다. 또 모체의 자궁을 적출하여 태자를 관찰하였다. 태자는 체중과 외형적 기형 그리고 alcian blue용액과 alizarin red S용액으로 염색하여 골격기형을 관찰하였다. 위와 같은 실험으로 다음과 같은 결과를 얻었다. 보생탕을 투여한 모체의 체중변화에서는 대조군보다 보생탕 투여군이 높은 증가율을 보였지만 전체적으로 두 군 모두 증가현상을 보였으므로 한약에 의한 체중 감소는 없는 것으로 사료되었다. 모체의 장기무게에서 절대중량은 대조군과 보생탕 투여군이 비슷한 결과가 나타났으며 상대중량은 간과 신장에서는 보생탕 투여군이 비장에서는 대조군이 높은 결과가 나타났으나 큰 차이가 나지 않았고 유의성도 나타나지 않았다. 혈액분석결과 백혈구, 적혈구 및 적혈구 관련지표 (MCV, MCH, MCHC), 헤모글로빈, 혈소판, 림프구, 중성구, 호산구, 호염기구, 단핵구등에서는 유의적인 차이가 나지 않았고, 모두 정상범위 이내에 속하였다. AST, ALT, BUN, Creatinine에서도 역시 큰 차이는 없었다. 이것도 역시 모두 정상범위였다. 모체의 황체수, 착상수, 착상율, 임신율, 초기소실율, 후기소실율, 출산자 수, 출산자의 성비를 보면 대조군보다 보생탕 투여군에서 약간 높은 결과를 보였으나 큰 차이는 없었다. 그리고 특히 초기소실율에서는 대조군보다 보생탕 투여군이 높은 결과를 보였다는 점에서 보생탕이 착상이나 임신유지에 유용한 영향이 있었다는 것을 볼 수 있었다. 태자에 대한 영향을 살펴본 결과 태자의 체중과 태자 수는 약간 증가한 것을 볼 수 있었으나 큰 차이는 나지 않았다. 그리고 태자 기형발생에서는 외형적인 기형은 관찰되지 않았고 골격검사에서도 관찰되지 않았다. 그러나 흉추와 흉골에서 변이가 다수 관찰되었다. 흉추에서는 대조군이 흉골에서는 보생탕 투여군이 약간씩 높았으나 대조군과 보생탕 투여군간의 변이는 큰 차이는 없었다. 그리고 천골과 미추에서는 수의 차이가 관찰되었으나 큰 차이는 없었고 미추에서는 유의성이 나타났다.(P<0.01) 그리고 늑골과 경추, 흉추, 요추는 그 수가 일정했다. 이상에서 보생탕 투여는 임신 모체와 태자의 체중 및 증체량의 증가를 촉진시키는 것으로 관찰되었으나, 기타 다른 모체 기능에 관한 지표, 즉 황체수, 착상수, 착상율, 임신율, 초기소실율, 후기소실율등에 영향을 주지 않는 점과 차세대 동물에 대한 검사에서 이상 소견이 관찰되지 않은 점으로 미루어 보생탕 투여는 랫드의 모체와 태자에 독성을 나타내지 않는 것으로 생각된다. 본 연구는 이러한 임신 중 한약의 안전성을 입증하는 연구 결과이며, 향후에도 이상의 결과와 국제 적 연구 경향을 참고하여 임신 중 한약의 안정성과 효과의 입증을 위한 지속적인 실험연구와 임상 보고들이 이루어져야 할 것으로 여겨진다.

  • Certain heavy metals which may lead peoples to poisonous status are widely used in industry and their uses have been increasing along with rapid industrialization of this country. Such an increasement of metal uses aggravates the status of environmental pollution affecting foodstuffs which are the most important life supporting factor of animal and humanbeing. Concerning the safety measures to minimize food-borne transmission of such hazardous metals, surveillance is the backbone of them and probably more so with a potential problem such as intoxication. Theoretically, this surveillance should include the determination of levels of heavy metal toxicants in foods, the determination of food consumption patterns and typical total diet, and the estimation of total load of the metal contaminant from all sources of exposure including air, water, and occupational sources. In recent year, actually, such estimates on the total daily intake of some heavy metals from foods have been made in several developed countries and a wide variation of date by season, locality, and research method was recognized. Also in this country, this kind of research data is vitally needed to make up for the serious shortage or lack of references to estimate the total amount of heavy metal intake of the people. In this study, a modification model for estimation of the total daily intake of cadmium copper, nickel, zinc, and lead through foods was applied and concentrations of the above metals in crops cultivated in this country were measured with atomic absorption spectro photometer to get the following results. 1. Level of heavy metal concentration in crops Generally, the levels of such metals in essential crops such as rice, cucumber, radish. chinese cabbage, apple, pear, grape, and orange are similar or lower than those in Japan and other developed countries. By the way, a striking result on cadmium concentration was increasement of its concentration in rice from $0{\sim}0.035ppm$ in 1970 to 0.11ppm in this study. However, the value is still far below the. Japanese Permissible Lebel of 1.0ppm. 2. Estimation of total daily intake per capita from foods A new model for estimation was devised utilizing levels of metal concentration in foods, amount of food consumed, and other food factors. Based on the above method, the daily intake of cadmium was estimated to be $70.53{\mu}g/man/day$ in average which was as high as the Limit Value of ILO/WHO(up to $71.4{\mu}g/man/day$). Also, 3.89mg of Zinc, 1.65mg of cuppor, 0.32mg of lead were given as the total daily intake per capita by this research. 3. Efficacy of washing or skinning to decrease the amount of metals in crops After washing the crops sufficiently with commercial linear alkylate sulfonate, the concentration of heavy metals could be reduced to $50{\sim}80%$ showing decreasement rate of $20{\sim}50%$. Also, after skinning the fruits, decreasement rate of the heavy metal concentration shelved $0{\sim}50%$.

  • Objectives: This investigation is purposed to evaluate the airborne asbestos concentrations in the public buildings having asbestos containing materials(ACMs) in Seoul. Methods: The Seoul Metropolitan Government carried out an asbestos survey to the city-owned public buildings to identify the level of risk exposure, classified into low, moderate and high risk. To evaluate the airborne concentration of asbestos, 11 sampling sites in ten buildings based on the survey were selected. The air samples from the eleven sites were analyzed by Phase Contrast Microscopy(PCM) and Transmission Electron Microscopy (TEM), and compared the analytical results from the both. Results: 1. The airborne fiber concentrations by PCM were less than the detection limit($7f/mm^2$) in 9(82%) out of 11 sampling sites. The highest concentration was 0.0043 f/cc, but it was below the guideline value for indoor air quality(0.01 f/cc), proposed by the Ministry of Environment, Korea. 2. In two sampling sites, having moderate risk level, the chrysotile was identified and showed it's concentrations of 0.0102 s/cc and 0.0058 s/cc, less than $5{\mu}m$ lengths. 3. The ACMs identified in the two sampling sites were a packing material(65% of chrysotile) in mechanical area and a thermal system insulation(5% of chrysotile) in a boiler room. Having more possibility of asbestos emission in the mechanical area, it would be required to set up and carry out the asbestos management plan. Conclusions: Based on the result of this study, the airborne asbestos concentrations in the public buildings with ACMs were generally lower than the guideline value for indoor air quality. There are widespread concerns about the possible health risk resulting from the presence of airborne asbestos fibers in the public buildings. Most of the previous studies about airborne asbestos analysis in Korea were performed based on PCM method that asbestos and non-asbestos fibers are counted together. In the public and commercial buildings, having ACMs, it is suggested that the asbestos be analyzed by TEM method to identify asbestos due to concerns about asbestos exposure to workers and unspecified people.

  • Objectives: Aluminum is well known as a potent neurotoxicant. There are many reports that aluminum can be toxic to humans and to animals. However, there are only few studies on the assessment of aluminum exposure among humans in Korea. Therefore, the aim of this study was to evaluate current aluminum concentrations among the adult population in regions of Korea. Methods: We selected 439 adults aged 20-89 years from the Busan-Ulsan-Gyeongnam region and certain other sites. Blood aluminum concentrations were analyzed using inductively-coupled plasma mass spectrometry (ICP/MS). The geometric means (GM) and 95% confidence intervals (CI) of aluminum concentrations were calculated, and we also confirmed the proportion of excess of the aluminum reference value. Results: Total GM (95% CI) of aluminum levels was 14.26 (13.43-15.14) ppb. Levels among males (15.58 [14.09-17.22] ppb) were higher compared to among females (13.51 [12.54-14.55] ppb), and levels increased with subject age from 40 years and over. Three point one nine percent of the subjects exceed the reference value of 50 ppb. Lastly, aluminum concentration has a log-normal distribution with lnN (x; 2.89, 0.642), x>0. Conclusion: In the present study, we evaluated the distribution of blood aluminum concentrations among the normal population in Korea, and we found some adults exceeding the reference levels. However, in order to compare the results with other studies, an extended study including measurement of serum aluminum level is required. In addition, further research on various population groups, including occupational exposure of workers, is required.
