In this transcultural comparison, we examined areas of stress, coping strategies and psychosomatic symptoms resulting form such strategies in Chinese, Korean-Chinese and Korean high school students. A total of 1,042 second-year high school students participated in this study : 213 Chinese from Yanbien, China ; 368 Korean-Chinese from Yanbien, China ; and 466 Koreans from Seoul, Korea. We administered the Stress Questionnaire Form for High school Students(Won & Lee 1995), the Ways of Coping-Revised(Lazarus & Folkman 1984) and the Physical Symptom Scale of Stress(Allen & Hyde 1980) to investigate areas of stress, coping stategies and psychosomatic symptoms, respectively. The findings were understood and interpreted from focus group discussions. Although there were no differences in total stress scores among the three groups, there were significant differences in areas of stress. Chinese students manifested the highest stress scores in peer relation, family problem, heterosexual problem, the future-employment, and religious problem. Koreans scored the highest in academic performance, school life, extracurricular activity, psychological-personality problem, value system, and the future-employment. The Korean-Chinese students scored the highest in extracurricular activity, family-economic problem. In terms of collectivism versus individualism, Chinese students' stress was related more toward the collective situation, whereas the Korean students faced increased stress regarding the individual situation. In coping strategies, the Chinese were characterized by active coping, Koreans by passive coping and Korean-Chinese by a mixture of the two. Koreans had the highest scores in psychosomatic symptoms, suggesting unfavorable coping strategies. The Korean-Chinese students seemed to lie intermediate between Koreans and Chinese in all three study areas, implying their chltural pluralism.

이누리 ( Nu Ri Lee ),홍창용 ( Chang Yong Hong ),김성은 ( Seong Eun Kim ),정용재 ( Yong Jae Chung ) 공주대학교 문화재보존과학연구소 2020 문화재과학기술 Vol.15 No.1

과거 문헌에서 직물 세척제로 기록된 다양한 천연재료 중 무즙과 도라지즙을 대상으로 세척성과 안정성을 확인하였다. 세척제로 무즙, 도라지즙, SDS, 증류수를 선정하였고, 직물 시편으로 면포, 곰팡이 오염포, 습식인공오염포를 선정하였다. 세척성 평가는 실체현미경 관찰, 색도 측정, 오염제거율 측정을 실시하였고, 안정성 평가는 면포와 오염포를 대상으로 실체현미경 관찰, 색도 측정, 직물pH를 측정하였다. 세척성 평가 결과, 무즙과 도라지즙은 일반 오염보다 곰팡이 오염 세척에 효과적임을 알 수 있었으며, 무즙이 도라지즙보다 세척성이 높았다. 안정성 평가 결과, 무즙과 도라지즙은 섬유 손상이 확인되지 않았으며, 무즙은 pH 측정 결과 중성으로 나타났다. 따라서 무즙이 면직물세척제로써 활용될 수 있을 것으로 기대된다. The purpose of this study is to prove the textile detergency and stability of radish juice and balloon flower root juice among the various natural meterials recorded as textile cleaning agents in historical record. Radish juice, balloon flower root juice, sodium dodecyl sulfate, and distilled water were selected as textile cleaning agents, and fungal soiled fabric and artificially soiled fabric were selected as fabric specimens. Detergency evaluation was performed by stereo-microscope observation, chromaticity measurement, and soil removal measurement. And the stability evaluation was conducted stereo-microscope observation, chromaticity measurement, and fabric pH measurement for the unsoiled and soiled fabric. As a result of detergency evaluation, radish juice and balloon flower root juice were more effective in cleaning fungal contamination than general contamination, and radish juice showed higher detergency than balloon flower root juice. As a result of stability evaluation, radish juice and balloon flower root juice did not show any fabric damage, and pH of fabric cleaned with radish juice appeared neutral. Therefore, radish juice can be used as a cotton fabric cleaning agent.

Eccrine porocarcinoma is a rare form of skin cancer that is often confused with other types of skin malignancy. The most common presentation is that of a red, ulcerated, dome-shaped nodule with shiny surface. It could also show as a wart-like plaque. A 81-year-old woman came up with her 2.5cm x 1.5cm sized hyperkeratotic plaque with crust on her right thigh, which lasted for a year. She had a total knee replacement arthroplasty on June, 2013. When she discharged, scar developed at the site of surgery. The lesion started as a erythematous plaque a year before. Moreover, lesion showed ulceration and crust associated with pain for a month. The biopsy section from her right thigh showed nesting structure with cells that are smaller and more basophilic than keratinocyte. Inside of the nested cells, ductal structures were seen. Until now, she had a wide excision and went through close follow-up with hemato-oncology department. There are several reports about skin tumors arising in at the site of scars, but few cases have been reported about eccrine gland origined tumor. There have been no reports of eccrine porocarcinoma arising at the site of scars in Korean dermatologic literature so far.

This study was to investigate the effects of high-fat diet feeding for a very long period of time on gene expression of inflammatory cytokines in mouse adipose tissue and to determine whether caloric restriction (CR) or insulin sensitizer treatment changes the cytokine gene expressions even in obese mice fed a high-fat diet for a very long term-period. Gene expression levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1) were examined by real-time PCR in subcutaneous abdominal adipose tissue (SubQ) from obese and non-obese male C57BL/6 mice at 16, 26, 36, 47, and 77 weeks of age on either normal diet (ND) or high-fat diet (HFD) after starting at 6 weeks of age. In addition, gene expression levels of TNF-α, IL-6 and MCP-1 were determined in SubQ before and after rosiglitazone treatment or CR on 47-week-old obese mice. The results demonstrated that gene expression levels of TNF-α, IL-6 and MCP-1 were significantly increased with aging in SubQ of mice in both groups of diet. MCP-1 gene expression of SubQ in all ages tested was significantly or marginally increased in mice on HFD compared with ND. While TNF-α expression was significantly reduced by rosiglitazone, IL-6 and MCP-1 were significantly decreased by CR. The basic data in this study will be useful for characterizing the C57BL/6 mouse as an animal model of obesity induced by high-fat diet feeding for a very long period of time, and a better understanding of inflammatory cytokine regulation in diet induced obesity which may facilitate the development of new therapeutic strategies to prevent the complications of obesity.

A case of herbal medicine induced arsenic keratosis

( Yong-woo Choi ),( Hyungrok Kim ),( Osung Kwon ),( Nu-ri Na ),( Hyun Chung ),( Joonsoo Park ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1

Medication induced arsenic keratosis has been recognized as the less common types of arsenic keratosis. The major cause of the disease relies on the chronic arsenic poisoning. As the hazardous effects of arsenic were disclosed, the material was classified as blastomogen by the International Agency for Research on Cancer (IARC) and US Environment Protection Agency (EPA) and its usage has been strictly prohibited since then. Arsenic has, however, shown some therapeutic levels that exhibit detoxifying, dehydrating, preserving abilities with the addition of controlling itch. It has been controversially used in treating some of the chronic inflammatory skin disorders. However, the window of therapeutic index for arsenic has not been clarified and the risk of arsenic poisoning exists, possibly causing condition such as arsenic keratosis. Herein, we report a case of arsenic keratosis by a 66-year-old man to provide clinical characteristics, and diagnostic measures along the treatments in order to enhance the precision and understanding of the disease. The number of arsenic keratosis induced by herbal medication in the Korean dermatological literature is scarcely limited to a single case. Thorough medical histories including the use of arsenic, with corroborative diagnostic measures to detect arsenic are the crucial factors in delivering the correct diagnoses.

A case of steroid induced perioral dermatitis

( Yong-woo Choi ),( Hyungrok Kim ),( Osung Kwon ),( Nu-ri Na ),( Hyun Chung ),( Joonsoo Park ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1

Perioral dermatitis is a common and oftenly found type of chronic dermatosis. Majority of the patients are women with age of 15 to 45, but there are also variants including lupus-like and granulomatous perioral dermatitis, while the latter is more common in childhood and affects mostly prepubescent boys. The etiopathogenesis of the disease remains unclear, but there is a frequent finding of prolonged use of topical corticosteroids in the treatment of rosacea and seborrheic dermatitis preceding the clinical manifestation of perioral dermatitis. Papulovesiclular eruption in the perioral region with a typical narrow spared zone around the edge of the lips is its characteristic clinical feature. Therapeutic approach should be individually addressed, depending on the severity of symptoms and the patient’s age, with special attention to education and continuous psychological support of the patient. In the initial treatment period, patients with steroid-induced perioral dermatitis should be closely followed up because the rebound phenomenon usually develops after cessation of previous topical treatment. There is concern about excessive misuse of topical steroids to uncharted dermatosis by non-dermatologist physicians. Moreover, misuse of topical steroids can aggravate dermatosis. There has been no reports of steroid induced granulomatous perioral dermatitis in Korean dermatologic literature so far.

A case of cloacogenic carcinoma mistaken to condyloma accuminatum

( Nu-ri Na ),( Hyungrok Kim ),( Osung Kwon ),( Yong-woo Choi ),( Joonsoo Park ),( Hyun Chung ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1

Cloacogenic carcinoma is a rare tumor of the anorectal region accounting for 20% of anorectal carcinoma. The tumor arises from the mucosa or the glands of a small zone of transitional epithelium at the anorectal junction as the remnant of the embryonic cloaca. Cloacogenic carcinoma must be differentiated from carcinomas of the anus and rectum, and from such inflammatory lesions as hemorrhoids and abscess but it may originate anywhere along the path of the ducts, they are occasionally found in the rectum or anus separate from the cloacogenic mucosa. And the many presentations and histologic appearance of cloacogenic carcinoma make clinical diagnosis difficult The patient was 79 years old man, who had hypertension ,diabetic mellitus, atrial flutter for several years. From 3month ago for visit, about 3cm sized soft erythematous plaque arised at Right perianal area. At first the patient had no symptom and the lesion looked like benign inflammatory disease, so it was mistaken for condyloma accuminatum. On biopsy, it was diagnosed with cloacogenic carcinoma with dual differentiation of pagetoid disease and Squamous cell carcinoma. On further evaluations, CEA level was normal, and there was no metastasis on radiologic evaluation. Because cloacogenic carcinoma can be easily mistaken for other anorectal disease like our case, and there have been only few reports of cloacogenic carcinoma, we report this case with our experience
