Syringocystadenoma papilliferum (SCAP) is a benign adnexal tumor, thought to have derived from either apocrine or eccrine gland. The term tubulopapillary hidradenoma (TPH) represents a spectrum of lesions that includes tubular apocrine adenoma and papillary eccrine adenoma, and these are also closely related to SCAP. A 68-year-old female with medical history of diabetes mellitus, hypertension came to our clinic complaining of a 2x1cm-sized erythematous dome-shaped nodule on the anterior chest for several months. Microscopic examination showed the proliferation of apocrine ductal and glandular epithelium, lined with a double layer epithelium composed of basilar cuboidal cells and an inner columnar layer of eosinophilic secretory cells and numerous tubules in dermis, with apocrine decapitation secretion and plasma cell infiltration. From such histopathologic findings, a diagnosis of SCAP mixed with TPH was made. The lesion was surgically excised with clear resection margin. We report an unusual case of a SCAP co-existing with a TPH.

Photochemical properties and shape evolution of CdSe QDs in a non-injection reaction

Park, Eunjung,Ryu, Jiyoung,Choi, Youngseon,Hwang, Kwang-Jin,Song, Rita IOP Pub 2013 Nanotechnology Vol.24 No.14

<P>Highly monodispersed CdSe quantum dots (QDs) were prepared without an injection procedure. A series of Cd salts of long chain fatty acids, including Cd-myristate (C14), Cd-palmitate (C16) and Cd-stearate (C18) was prepared, and all metallic precursors and surfactants were mixed together followed by increasing the temperature in a controlled manner. The reaction resulted in highly monodisperse and bright zinc blende QDs. In addition, the effects of specific ligands which have been known to lead anisotropic growth of the nanocrystals in the injection method were investigated. The use of alkyl phosphonic acid and alkyl amine was found to produce extremely monodisperse CdSe QDs with a high quantum yield. This procedure was proven to be able to yield a large quantity of zinc blende CdSe QDs (2 g) in a one-pot reaction. The use of a controlled amount of tetradecylphosphonic acid and octadecylamine resulted in tetrapod- and match-shaped QDs, the first reported by a non-injection method. These results clearly demonstrate that appropriate combination of precursors can provide high quality of CdSe nanocrystals in terms of quantum yield, monodispersity and shape control by a non-injection method.</P>

Toward Multiculturalism through American Ethnic Studies in the Globalizing World

Eunjung Park 한국외국어대학교 영미연구소 2004 영미연구 Vol.10 No.-

This paper aims to develop several ideas of multiculturalism, American ethnic studies, and American globalization to better understand the relationships among them. The U.S. can be a center of globalization process. While the term ‘globalization’ originates from the area of international trade and business, this paper tries to focus on the cultural aspects of globalization. Academia and government in the U.S. have developed policies emphasizing ethnic diversity and multiculturalism that embrace incoming immigrants. Ethnic studies is an area in academia to understand others and intersect the common experience among different cultures in the U.S. While many Americans try to de-emphasize racial differences, ethnicity emerges as rather an important term in the process of globalization in the U.S. Different and diverse cultures in the U.S. are exposed to the mass with their own ways of lives, religions, food, and customs, but they still believe all of them are Americans enough to assume the same American identity. This paper attempts to define globalization, which is quite different from American nationalism, imperialism, or internationalism. Globalization exists somewhere between the First World metropolitan global city and the Third World NGO’s indigenous area, between multiculturalism and ethnicity. It has its own “world system” by intervening in international civil society. With a global spirit people go with transnational idea, and migrate to several metropolitan global cities to earn money. Most of the monetary fund is poured into the global cities, where people enjoy their diverse and unique cultures in their own imagined community. That is the reason ethnic belonging and ethnic studies should be embraced as part of globalization in the U.S. In conclusion, this paper contends that a vision that the equality of multicultural phenomena in the U.S. can accomplish the ideal model of globalization for the world. So everybody who tries to move toward globalism feels at home even in a global city, and they can succeed in their pursuits of reaching beyond nationalism.

Hydrochlorothiazide use and risk of skin cancer: A nationwide retrospective cohort study in Korea

( Eunjung Park ),( Young Lee ),( Mihn-sook Jue ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Hydrochlorothiazide (HCTZ) is the one of the most commonly prescribed antihypertensive drug and recent data has shown an association between HCTZ use and skin cancer (SC). However, there have been no studies about HCTZ use and the risk of SC in Asian population. Objectives: Examine the risk of SC in the cohort of Korean hypertension patients. Methods: We conducted a retrospective, population-based cohort study using database from the Health Insurance Review and Assessment (HIRA) Service from 2009 to 2016. The risk of SC was evaluated by multivariable Cox proportional hazard ratio (HR) modeling. Covariates included age, sex, comorbidities and prior history of photosensitizing drugs and other medications known to potentially affect the SC risk. Results: A total of 1,714,590 patients with HCTZ-users and 1,851,362 of non-HCTZ users were enrolled. The overall risk of SC was 42.67 and 40.23 per 1000,000 person-years in HCTZ-users and non-HCTZ users, respectively. Compared with non-HCTZ users, no statistically significant associations with the risk of all SC in HCTZ-users (HR=0.97, 95% CI, 0.93-1.02, p=0.26). Whereas, the risk of melanoma was decreased in the HCTZ-users (HR=0.89, 95% CI, 0.81-0.99, p=0.03), and no statistically significant association was seen in the risk of nonmelanoma skin cancer (NMSC) (HR=0.99, 95% CI, 0.94-1.04, p=0.77). Conclusion: Use of HCTZ use maybe associated with decreased risk of melanoma, and no association in the risk of NMSC.

Park, Mi-Hyun,Han, Yeong-Deok,Kwon, Choon Bong,Lee, Eun Sun,Kim, Ji Hye,Kang, Youn Seung,Kim, Se-Joo,Yang, Hee-Min,Park, Taeseo,Yoo, Jung-Sun,Kil, Hyun-Jong,Nam, Eunjung,Shin, Mann Kyoon,Min, Gi-Sik The National Institute of Biological Resources 2017 Journal of species research Vol.6 No.no.spc

In this list-format paper, we present unrecorded species of Korean ciliates (phylum Ciliophora). All species were selected from the final reports of the project: "Discovery of Korean Indigenous Species". This project has been carried out to discover and record various Korean indigenous species since 2006 and is funded by the National Institute of Biological Resources (NIBR). Among the various species, ciliates were a major taxon that was highlighted in this project as a speciose group categorized under Protozoa. This paper contains reports of 38 ciliates (8 classes, 16 orders, 23 families, and 34 genera) observed in Korea during the initial five years of the project (2006-2010).

Long-Term Changes of Body Mass Index and Nutritional Biochemical Markers in the Obese Elderly with Gastric Cancer

( Eunjung Kim ),( Ji-hyeon Park ),( Eun-mi Seol ),( Seong-ho Kong ),( Do Joong Park ),( Han-Kwang Yang ),( Hyuk-joon Lee ) 한국정맥경장영양학회 2021 한국정맥경장영양학회지 Vol.13 No.2

Purpose: This study investigated change of body mass index (BMI) and nutritional biochemical markers after gastrectomy according to the preoperative obesity in the elderly gastric cancer patients, and evaluated their short- and long-term clinical outcomes. Materials and Methods: Gastric cancer patients (age≥65 years, BMI≥25 kg/㎡) who underwent curative gastrectomy from 2014 to 2015 were enrolled in this study. BMI, comorbidity, extent of surgical resection, surgical approaches, postoperative complications, cancer stage, adjuvant chemotherapy, and survival data were collected. Nutritional parameters were collected until 4 years after surgery. The patients were classified into two groups according to preoperative BMI: Obesity group (25 kg/㎡≤BMI<30 kg/㎡) and severe-obesity group (BMI≥30 kg/㎡). Results: Of the total 266 patients, 210 patients were categorized as the obesity group and 16 as the severe-obesity group. Postoperative complications were comparable between the two groups. The BMI decreased by more than 10% at 12 months after gastrectomy, and remained at a similar level during the 4 year-follow-up period in both groups. At 4 years after surgery, the nutritional biomarkers were nearly comparable to preoperative levels in each group. The severeobesity group were associated with poor overall survival rate (P=0.011). Conclusion: BMI decreased by more than 10% after gastrectomy in obese elderly, but nutritional biomarker levels were comparable before and after gastrectomy. The overall survival rate was lower in severely obese elderly than in obese elderly. Therefore, it is considered that severely obese elderly gastric cancer patients should be monitored, and vigorous efforts are needed to reduce high-BMI.

[P097] Angioleiomyoma of the finger: an unusual presentation

( Eunjung Park ),( Mingyul Jo ),( Jisook Yoo ),( Mihn-sook Jue ),( Kwang-hyun Choi ),( Min-soo Kim ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Angioleiomyoma is a benign vascular neoplasm derived from the smooth muscle cells of arterial or venous walls. Angioleiomyoma occurs in the lower extremities most frequently, and less common on the trunk, head, and upper extremities. A 80-year-old female with medical history of diabetes mellitus, hypertension, depressive disorder came to our clinic complaining of about a solitary painful, slowly-growing subcutaneous nodule on the right 5th metacarpophalangeal (MCP) joint of finger from several months ago. Histopathological examination of the skin lesion showed diffuse vascularized subcutaneous nodules composed of well-differentiated smooth muscle fibers without cellular atypia. Immunohistochemical stain was positive for smooth-muscle actin (SMA), but negative for HMB-45, confirming the diagnosis of angioleiomyoma. The patient refused the complete excision of the tumor. Angioleiomyoma on the finger is uncommon, and to the best of our knowledge, there was no case of the angioleiomyoma on the finger in the dermatologic literature in Korea. We herein report a rare case of angioleiomyoma on the finger.

[P098] Extradigital glomus tumor on the upper arm

( Eunjung Park ),( Mingyul Jo ),( Jisook Yoo ),( Kwang-hyun Choi ),( Min-soo Kim ),( Mihn-sook Jue ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

A glomus tumor is a rare vascular neoplasm arising from the glomus body and the most common site is hand, especially subungual region of the finger and palm. A 68-year-old male with medical history of colon cancer with liver metastasis came to our clinic complaining of a solitary painful erythematous papule on his right upper arm for about one month. The patient had no history of trauma. Physical examination revealed a 0.7cm-sized, dome-shaped, painful erythematous papule with significant tenderness on posterior aspect of right upper arm. We performed punch biopsy under the impression of cutaneous metastasis of the cancer or hypertrophic scar. Skin biopsy showed varying proportions of glomus cells, blood vessels, and smooth muscle, and monomorphic round cells with eosinophilic cytoplasm. Immunohistochemistry stain was positive for smooth-muscle actin (SMA), whereas S100 and HMB45 were negative, confirming the diagnosis of solid type of glomus tumor. The lesion was removed from the biopsy, and there was no evidence of recurrence after 10 months of follow-up. We herein report a rare case of extradigital glomus tumor on the upper arm which is occasionally difficult to diagnose before histological and immunohistochemical confirmation.
