The present study was conducted to accomplish management efficiency by preparing preemptive measures for consumer dissatisfaction and overcome risks caused by Global Warming through studies of model cases in packaging. Through this study, we made it possible to find a way for companies to prepare for Global warming and consumer dissatisfaction. By contributing to eco-friendly packaging, we are trying to preemptively respond to recent major issues through packaging. Through this experiment, we tried to measure the degree of penetration of Plodia interpunctella H. larva into the insect repellent film produced by printing Ink containing a natural repellent. The control experiment was conducted with an untreated LDPE film to which no insect repellent was applied. The numbers decreased from 17 to 7 when the film was processed with repellent to show experimental results verifying effects of repellent by decrease in 10 (58.8% Decrease). Such results show that it is safe when the film is unfolded but in the case where the film is folded, the Plodia interpunctella H. punches through the film to lead to consumer dissatisfaction and it suggests that this can bring on risks to corporate management. Considering that most of the film is folded in the case of PE bag packaging, the direction which the corporations should take in terms of preparing for climate change countermeasures and consumer dissatisfaction has been clarified. Due to it receiving satisfactory results in safety rest results for printing film applied with pest repellent as well as the Quality analysis to test repellent contents of repellent film, it is certain that the importance of repellent method in packaging will increase in preparing for consumer dissatisfaction and actions against climate change henceforth.

Background: Emergencies in dentistry can be classified as medical and dental. Medical emergencies occur mainly during dental treatment in patients with a systemic disease. Dental emergency departments are largely divided into dental emergency rooms located in dental college hospitals and medical emergency rooms located in medical institutions. This study aimed to analyze the characteristics of and provide help to dental emergency patients in a dental hospital. Methods: Overall, 1806 patients admitted to a dental emergency room at Yonsei University Dental Hospital for 1 year were included. The data collection period was from October 1, 2014 to September 30, 2015. An investigator reviewed medical records from the electronic medical record (EMR) system and radiographs. Results: The patients were 1,070 men and 736 women. The sex ratio was 1.45:1. The commonest age group was of 0-9 years, including 451 (25.0%) patients, followed by 20-29 years, including 353 (19.5%) patients, and 30-39 years, including 277 (15.3%) patients. Of the 108 patients transferred to the Severance emergency department, 81 had trauma, 19 were in pain, 4 were bleeding, and 4 had other complaints. Among chief complaints, 1,079 patients (60.3%) had trauma, 564 (31.5%) had pain, and 75 (4.2%) had bleeding. Twenty-three cases (1.3%) were caused by temporomandibular disorder (TMD). Conclusion: Dentists should be able to adequately assess patients in a dental emergency room and treat trauma, pain, and bleeding.

우리나라의 대표적인 주거형태는 공동주택이다. 이로 인해 생활 소음으로 인한 민원 발생이 급증하고 있는 상태이다. 이에 실생활에서 주변 소음으로 인해 고통을 받는 경우에는 소음 측정기로 측정하여 민원을 제기할 수도 있다. 그러나 일반 가정에서는 전문적인 장비를 동원해 소음 측정을 하기가 어렵기 때문에 간편하게 스마트폰 앱을 사용하는 경우가 많다. 기존에 출시된 소음 측정 앱은 스마트폰의 기종별로 센서의 감도가 달라 동일한 조건에서 측정하여도 값이 다르게 나오는 등 정확도가 현저히 떨어지며, 실제 소음 측정을 위한 목적으로 사용하기가 어렵다. 따라서 본 논문은 스마트폰을 이용한 생활 환경의 소음 측정을 위한 모바일 데이터 처리 시스템을 제안한다. 본 연구의 기대 효과는 소음 측정의 정밀도를 높이고 소음이 발생하는 위치를 검색하여 민원처리에 활용할 수 있다.

Objectives: This study was aimed to report changes in clinical symptoms and signs after treatment with Korean medicine in patients who suffered from calf edema due to deep vein thrombosis (DVT). Methods: A 46-year-old male patient, who discharged home after receiving standardized treatment for acute DVT in the right leg, suffered pain and heat sense due to edema of the affected calf. Oral administration of herbal medicine (Gyejibongnyeong-hwan 4 g, twice daily) and acupuncture therapy were given to him for 6 weeks. The change in chief complaints, Villalta score, the right and left side difference of the circumference and the skin surface temperature of both calves, and blood level of D-dimer were observed before and after treatment. Results: The patient's chief complaints began to significantly improve from 2 weeks after treatment, and disappeared completely within 4 weeks. At the end of the treatment, a substantial decrease in the difference between the right and left calves in the circumference and skin surface temperature was observed. This effect was maintained even at the time of follow-up 3 months after the end of treatment, and the patient completely recovered indoor and outdoor life to the level before onset. Conclusions: This case suggests that Korean medicine treatment, including Gyejibongnyeong-hwan administration and acupuncture therapy, can be a viable option to improve edema and related clinical problems in the affected limbs due to DVT.

Objectives: Low back pain (LBP) is a common chronic condition among sedentary workers that causes long-term productivity loss. This study aimed to identify the relationships of individual and occupational factors with LBP among Bangladeshi online professionals. Methods: We conducted a cross-sectional study involving 468 full-time online professionals who usually worked in a sitting position. One-month LBP complaints were assessed using a musculoskeletal subscale of subjective health complaints. The chi-square test was used to measure associations between categorical predictors and LBP, and multivariable logistic regression was conducted to identify the variables significantly associated with LBP. Results: LBP within the last month was reported by 65.6% of participants. Multivariable logistic regression analysis indicated that age >30 years (adjusted odds ratio [aOR], 0.40; 95% confidence interval [CI], 0.23 to 0.70) and being married (aOR, 0.59; 95% CI, 0.36 to 0.97) had significant negative associations with LBP. Significant positive associations were found for spending >50 hours weekly on average working in a sitting position (aOR, 1.61; 95% CI, 1.05 to 2.49), being overweight and obese (aOR, 1.87; 95% CI, 1.16 to 2.99), sleeping on a soft mattress (aOR, 2.01; 95% CI, 1.06 to 3.80), and ex-smoking status (aOR, 3.33; 95% CI, 1.41 to 7.87). Conclusions: A high prevalence of LBP was found among full-time online professionals. Long working hours in a sitting position showed a significant association with developing LBP. Smoking history, body mass index, and sleeping arrangements should also be considered while considering solutions for LBP prevalence among online professionals.

Background: Acupotomy is a type of acupuncture where a scalpel-shaped needle (miniscalpel needle) is used instead of a normal acupuncture needle to exfoliate adhesion sites or to relax entrapped regions. This study aimed to identify the descriptive characteristics of patients who received acupotomy treatment at a single Korean Medicine Clinic. Methods: This retrospective review analyzed the medical charts of patients who had received acupotomy at least once from August 2017 to December 2019 at a single Korean Medicine Clinic. The demographic characteristics, chief complaints, acupotomy treatment sites, and principal diagnosis codes were analyzed. Results: We identified 551 outpatients; the average age was 52 ± 14.26 years and 49.9% were male. The patients underwent an average of 8.47 sessions of acupotomy. Altogether, 35.91% of the acupotomy treatments were administered to the spinal regions, of which 60.01% were in the lumbar region. The codes related to the lumbar spinal condition/disease which were used most frequently. The chief complaints were dizziness, lumbar spinal stenosis, and Dupuytren's contracture in patients over 60 years of age. Conclusion: This is the 1^st analysis of acupotomy treatment patterns in Korea to date. Acupotomy is primarily administered in the treatment of spinal conditions/diseases, especially for those involving the lumbar region. Future studies are necessary to determine the clinical outcomes of patients who receive acupotomy treatment and the safety of this treatment.
