Background: The objective of the present study is to identify differences in the prevalence of acute occupational pesticide poisoning across Korean orchard farmers" farming characteristics and the risk factors that have an effect on acute occupational pesticide poisoning. Methods: For 3 years (2014, 2015, and 2017), a questionnaire survey was conducted on 394 orchard farmers in some parts of south Chungcheong Province in relation to pesticide poisoning. 323 orchard farmers who responded to acute occupational pesticide poisoning were included for final analysis. With acute occupational pesticide poisoning as the dependent variable, a χ2 test and a multiple logistic regression analysis were conducted. Results: The results of the prevalence of acute occupational pesticide poisoning across farming characteristics showed that the group wearing 4 or more pesticide personal protective equipment (PPE) had a lower prevalence of acute occupational pesticide poisoning than the group wearing 3 or less pesticide PPE (p < 0.05). Furthermore, an analysis by area of fruit farming revealed that the group with more than 12,000m² in the area of fruit farming had a higher prevalence of acute occupational pesticide poisoning (p < 0.05). Orchard farmers mainly use a speed sprayer to spray pesticides, and the speed sprayer can be categorized by presence of cabin. The analysis of the prevalence of acute occupational pesticide poisoning by speed sprayer"s cabin existence found that existence of speed sprayer"s cabin did not show a statistically significant difference in the prevalence of acute occupational pesticide poisoning. Conclusions: The present study analyzed the prevalence of acute occupational pesticide poisoning depending on the speed sprayer"s cabin existence and found no significant difference. The fact that famers using the cabinless style speed sprayer shows a higher percentage in wearing PPE than those using the cabin style speed sprayer is suggested to elucidate the result. As the first study in Korea which examined the prevalence of acute occupational pesticide poisoning by speed sprayer"s cabin existence, the present study proposes the expected effect that increase of wearing pesticide PPE along with employ of speed sprayer"s cabin can reduce the prevalence of acute occupational pesticide poisoning among orchard farmers.

<P>Delayed wound healing is one of the major diabetic complications. During wound healing process, the early inflammatory stage is important for better prognosis. One of antioxidant nutrient, gamma-tocopherol (GT) is considered to regulate inflammatory conditions. This study investigated the effect of GT supplementation on mechanism associated with inflammation, oxidative stress, and apoptosis during early cutaneous wound healing in diabetic mice. Diabetes was induced by alloxan injection in ICR mice. All mice were divided into three groups: non-diabetic control mice (CON), diabetic control mice (DMC), and diabetic mice supplemented with GT (GT). After two weeks of GT supplementation, excisional wounds were made by biopsy punches (4 mm). Diabetic mice showed increases in fasting blood glucose (FBG) level, hyper-inflammatory response, oxidative stress, and delayed wound closure rate compared to non-diabetic mice. However, GT supplementation reduced FBG level and accelerated wound closure rate by regulation of inflammatory response-related proteins such as nuclear factor kappa B, interleukin-1 beta, tumor necrosis factor-alpha, and c-reactive protein, and oxidative stress-related markers including nuclear factor (erythroid derived 2)-like 2, NAD(P) H dehydrogenase quinone1, heme oxygenase-1, manganese superoxide dismutase, catalase and glutathione peroxidase and apoptosis-related markers such as sirtuin-1, peroxisome proliferator- activated receptor gamma coactivator 1-alpha, and p53 in diabetic mice. Taken together, GT would be a potential therapeutic to prevent diabetes-induced delayed wound healing by regulation of inflammatory response, apoptosis, and oxidative stress.</P>

Background: Glyphosate and glufosinate use widely used as herbicide ingredients. There have been several reported cases of chemical burns caused by dermal exposure to glyphosate-containing herbicide, and patients in these cases were discharged without fatal complications. There were no cases of severe symptoms due to non-oral exposure of glufosinate-containing herbicides. Here, we report a case of fatality accompanied with severe chemical burns in an 81-year-old man who did not wash his skin for more than 48 hours after dermal exposure to herbicide containing glyphosate and glufosinate with surfactant (HGlyGluS). Case presentation: An 81-year-old male with no underlying disease was admitted to the emergency department (ED). He had sprayed HGlyGluS with a manual knapsack sprayer 3 days ago and had not wash away the herbicide. On arrival, he was drowsy and had multiple severe corrosive skin lesions. Skin necrosis (10 × 15 cm) on the right shoulder and skin lesions with subcutaneous fat exposure (15 × 20 cm) on the right thigh were observed. Although he was treated including continuous renal replacement therapy, antibiotic apply, debridement operations, and so on, he was unable to recover and expired. Conclusions: We suggest that prolonged dermal exposure to HGlyGluS induces fatality. Further studies including prolonged dermal exposure and ingredients of surfactants should be carried out. Also, it is necessary to educate farmers that it is very important to wash immediately after dermal exposure to pesticide.
복합외상경험자의 접촉 경계에 대한 분석적 자문화 기술지

본 연구는 복합외상 경험자의 경계없음을 게슈탈트 이론의 접촉 경계 혼란으로 보고, 상담과정을 통해 경계가 세워지는 과정에 대한 이해를 돕고자 하였다. 이를 위해 복합외상 경험자인 연구자의 상담 기록을 분석적 자문화 기술지를 적용하여 분석하였다. 분석 결과는 다음과 같다. 첫째, 복합외상 경험은 죽은 것 같은 경험으로 ‘내’가 사라진 상태와 같기 때문에 접촉경계 혼란 문제를 가지게 한다. 둘째, 경계 회복을 위해 신체의 알아차림을 증진시킬 수 있는 안정화 기법이 필요하다. 셋째, 복합외상 경험자들과의 상담에서 상담자의 경계 유지를 통해 내담자가 경계를 배울 수 있다. 넷째, 게슈탈트 영성 치료는 복합외상 경험자의 접촉 경계에 의미 있는 회복 경험이 될 수 있다. 마지막으로 연구의 의의와 한계, 후속 연구에 대해 제언하였다. 본 연구는 복합외상 경험자의 경계를 접촉 경계 혼란으로 이해하고 경계 회복을 위해 상담에서 적용할 수 있는 전략을 제시하였다는데 의의가 있다. This study viewed the lack of boundaries of a person who have experienced complex trauma as contact boundary confusion of the Gestalt theory and attempted to help understand how boundaries are established through the counseling process. To this end, the counseling records of the researcher who had experienced complex trauma were analyzed by applying analytical auto-ethnography. The analysis results were as follows. First, the complex trauma experience is like a state in which “I” has disappeared due to a death-like experience. This led to the problem of contact boundary confusion. Second, a stabilization technique that can improve the body’s perception is needed to restore boundaries. Third, when it comes to counseling with complex trauma experienced people, clients can learn boundaries through the counselor's maintenance of boundaries. Fourth, Gestalt spirituality treatment can be a meaningful recovery experience for the boundary contact of those who have experienced complex trauma. Finally, the significance and limitations of this study and subsequent studies were suggested. This study is meaningful in that it understood the boundaries of those who experienced complex trauma as contact boundary confusion and suggested strategies that can be applied in counseling to restore boundaries.
