지구온난화 및 병충해 발생 증가 등의 환경적인 요인은 안정적인 과실생산에 큰 위협이 되고 있다. 많은 과수 작물 중에서도 복숭아는 숙기 예측이 어렵고 쉽게 물러지는 특징이 있다. 특히 자연재해에 약하며 최근에는 이상기후로 인해 개화기와 수확기의 예측이 어려워지면서 많은 농가들이 피해를 받고 있다. 최근 농업 현장에서는 비파괴 센싱 기술 중에서도 초분광 영상 기술을 과실 생육 과정에 활용하여 수확 적기와 품질 예측을 통해 고품질의 과실을 생산하고자 많은 노력을 기울이고 있다. 본 연구는 복숭아 ‘마도카’ 과실의 수확기를 예측하고 수확 후 생육특징과 초분광 영상과의 상관관계와 그에 따른 신뢰도를 알아보고자 수행하였다. 초분광영상 취득은 SPECIM-IQ(SPECIM, SPECTRAL IMAGING LTD., Oulu, Finland) 카메라를 사용하였다. 수확 시기별 과실 30개씩을 7월 13일부터 3 ~ 5일 간격으로 6번 수확 후 180개 복숭아 과실에 대한 스펙트럼 데이터를 이용하여 모델링을 실시하였다. 복숭아 ‘마도카’를 필드, 마도카 전체 과실, 마도카 정중앙 과실의 과피와 과육 부분의 초분광 영상 스펙트럼(400 ‒ 1000nm)을 수집하고 영상을 분석한 결과, Core 과피 가용성 고형물 함량 예측 모델의 정밀도는 전처리하지 않은 경우 R² = 0.74, 평활화처리, 1차 미분, 2차 미분시 정밀도는 R² = 0.56 ~ 0.88로 나타났다. 복숭아 Core 과피의 고형물 함량 모델의 validation 결과, 전처리 전의 정밀도는 R² = 0.96을 보였고, 평활화처리, 1차 미분, 2차 미분시 예측 정밀도는 R² = 0.93 ~ 0.97의 예측성능을 보였다. 복숭아 과실 전체의 고형물 함량에 대한 모델은 전처리 전의 정밀도는 R² = 0.65를 보였고, 평활화, 1차 미분, 2차 미분시 예측 정밀도는 R2 = 0.73 ~ 0.88의 예측성능을 보였다. 복숭아 과실 전체의 고형물 함량 모델의 validation 결과, 전처리 전의 정밀도는 R² = 0.96을 보였고, 평활화, 1차미분, 2차 미분시 예측 정밀도는 R² = 0.97 ~ 0.98의 예측성능을 보였다. 따라서, VNIR 초분광 영상을 활용한 복숭아 과실의 가용성 고형물 함량 예측이 가능할 것으로 판단되었으며, 복숭아 숙도 선정에 필요한 다양한 수확 지표들에 대한 초분광 영상 적용성을 검토해야 할 것으로 판단되었다.

Bullae and sweat gland necrosis is an entity previously reported to occur in comatose patients. Since its first description in comatose patients after carbon monoxide intoxication, similar lesions have also been reported in comatose patients after overdose with several drugs and in immobilized non-comatose patients. To our knowledge, there have been only three occurrences of bullae and sweat gland necrosis after alcohol intake in the Korean dermatologic literature. These cases were never described, but only summarized in a table of an original article. Herein, we more fully describe a case of bullae and sweat gland necrosis in a non-comatose patient after alcohol intake. The case demonstrates conclusively that bullae and sweat gland necrosis can occur not only in a comatose patient but also in a non-comatose patient. (Korean J Dermatol 2011;49(11):1028∼1031)

Since its first description in 1887 as the appearance of psoriatic lesions in the uninvolved skin of psoriatic patients as a consequence of trauma, the Koebner phenomenon has been described in numerous diseases. Several types of injury can trigger the Koebner phenomenon, such as physical injury, surgical wound, irritation, sunburn, or radiation therapy. In this report, we describe a 43-year-old woman who developed erythema multiforme which was accompanied by the Koebner phenomenon after getting acupuncture and cupping glass therapy. The purpose of the report is to broaden our awareness of the spectrum of injury that can trigger the Koebner phenomenon. (Korean J Dermatol 2011;49(9):809~811)

Objectives : The aim of this study is to introduce the Korean medicine respiratory management program in public health center and to analyze the effects of that program. Methods : The respiratory management program was targeted on 22 soldiers during March 2016. The interventions of this program were herbal medicines (Gilgyung-tang and so on), aromatherapy, peppermint tea, fine dust mask, and health education. Data were collected by retrospective reviewing medical chart and analyzed using SPSS 18.0. Results : Total symptoms scores were measured by 4-point likert scale. Total score was $5.50{\pm}4.848$ at 1st week and $3.27{\pm}3.058$ at 4th week (p=0.008). The severity of respiratory discomfort reduced by $-1.14{\pm}2.46$ compared with last year. The satisfaction score was $7.82{\pm}4.16$. The most hoping program was muscular skeletal disease management program. Conclusions : This study suggests that Korean medical world should prepare countermeasures to cope with diseases caused by air pollution.
베체트병의 결절홍반모양 병변에 대한 임상 및 병리조직학적 고찰

Background: The clinical and histopathological aspects of erythema nodosum-like lesions (ELLs) in patients with Behcet`s disease (BD) may resemble those of classic erythema nodosum (EN). Although a few articles that compared ELL and EN in Korean patients have been published in the English literature, there is no comparative study between ELL and EN in the Korean dermatologic literature. Objective: The purpose of this study was to evaluate the clinical and histopathological differences between ELL and EN. Methods: We reviewed all the medical records, photographs and histopathological slides of 33 patients with ELL and 47 patients with EN at our clinic between 2000 and 2009. For all the patients, their diagnosis was confirmed based upon the clinicopathologic correlation and long term follow-up of at least more than 1 year. Results: Compared with EN, ELLs were associated with the following characteristics: a past history of inflammatory plaques and nodules (p=0.037), a relapsing course (p<0.001), dermal infiltration of neutrophils (p=0.001), mixed panniculitis (p<0.001) and subcutaneous vasculitis (p<0.001). In 6 patients (18.2%) the ELLs were the initial major symptom of BD and they didn`t have other main symptoms of BD. Compared with the patients with EN, all these patients had inflammatory plaques or nodules on other areas as well as on the lower extremities (p=0.006) and they had a relapsing course (p<0.001). In this group the mean duration of an initial major symptom to the diagnosis of BD was 16.7 months. Conclusion: Our results show that ELLs in BD can be distinguished from EN by some clinical and histopathological differences. Especially, in the patient with ELLs without other main symptoms of BD, the occurrence of lesions above the lower extremities and the relapsing course may be important clues to suspect a diagnosis of BD and to exclude a diagnosis of EN.

기준 설정 전인 2006년 식품의약품안전청에서 실시한 연구과 제의 결과보고서에 의하면 200건 벌꿀 중 네오마이신은 검출되지 않았고, 스트렙토마이신의 경우 23건이 검출되었으며, 아미트라즈(그 대사산물 포함), 코마포스의 경우 각각 10건, 9건의 검출되었다(8). 그러나 기준 설정 후인 본 연구의 모니터링 결과 해당 동물용의약품의 검출율이 현저하게 떨어진 것으로 미루어 볼때 07년 기준 설정 후 설정된 잔류허용기준에 맞춰 관리되고 있음을 알 수 있었다. This research was carried out to investigate residues of neomycin, streptomycin, dihydrostreptomycin, amitraz, 2,4-dimethylaniline (one of amitraz’s metabolites), and coumaphos in honey in order to intensively control their use following the establishment of Korean maximum residue limits (MRLs) for veterinary drugs in honey in 2007. To monitor for residues, 110 honeys and food products with honey were collected and analyzed. The collected honeys included acasia, mixed flower, chestnut, rape flower, jujube, and native types. Neomycin, streptomycin, dihydrostreptomycin, oxytetracycline, and amitraz were not detected among samples. Coumaphos was found in the Korean acasia honey at 0.02 mg/kg, but its concentration was under the MRL (0.1 mg/kg) for coumaphos. According to the results, there were no violations of the Korean MRLs of veterinary drugs in honey.
