Glomus tumors are benign neoplasms that are derived from modified smooth muscle cells known as glomus cells. Histologically, it can be subdivided as glomus tumor proper, glomangioma, and glomangiomyoma according to relative proportions of components. Glomangiomyomas are the least frequent type and their overall architectural pattern may resemble glomus tumor proper or glomangioma, but there is a gradual transition from glomus cells to elongated mature smooth muscle cells. This transition is most obvious in the region surrounding large vessels. We present a case of glomangiomyoma of the left upper arm and the left fourth finger, in which ten-year history of two painful, bluish-colored subcutaneous nodules. On histologic examination, this case showed marked smooth muscle cell proliferation around large vessles and mucinous stromal change. (Korean J Dermatol 2001;39(10) 1147-1151)

연구목적 본 연구는 故 최숙현 선수의 희생이 헛되지 않기를 바라는 마음으로 시작되었다. 연구대상은 2020년 스포츠폭력에 의해 고인이 된 최숙현 선수의 사망사건을 직·간접적으로 경험한 철인3종경기 선수 30명이다. 연구방법 연구방법은 내러티브의 3차원적 공간 중 개인적·사회적 차원과 내적·외적 지향에 중점을 두고, 연구 참여자의 스포츠폭력에 대한 인식과 경험을 개방형 질문으로 조사하였다. 이 후 추가적 심층면담을 실시하였다. 특히 참여자들이 현역선수들이기 때문에 연구참여중단의 가능성과 익명성을 보장하였다. 연구자는 25년간 트라이애슬론 선수로 활동을 하였으며, 직접 피해자이기도 하다. 결과 자료의 귀납적 범주화 결과, 스포츠폭력 사건에 대한 인식에는 기본신념 붕괴, 제도적 문제, 우려, 감정 등이 나타났다. 인지된 내적 변화에는 부정적 영향 없음, 제도적 문제, 간접 트라우마 등이 나타났다. 인지된 외적 변화로는 부정적 영향 없음, 간접 트라우마 등이 나타났다. 지각된 변화로는 변화와 기타로 나타났다. 변화의 시발점은 처벌에 대한 생각, 감정, 제도적 문제 등이 도출 되었으며 변화의 방향성으로는 2차 피해 우려, 확실한 변화 요구, 제도적 해결책 필요 등으로 나타났다. 결론 결과를 토대로 트라이애슬론의 스포츠폭력 사건에 대한 답변을 시간의 흐름 순으로 정리하여 새로운 패러다임 모형을 제시하였다. Purpose This study was started with the hope that the sacrifice of the deceased player, Sook-Hyun Choi, would not be in vain. The subjects of this study were 30 Korean triathletes who directly or indirectly experienced the case of Choi Sook-hyeon, who died of sports violence in 2020. Methods The research method focused on personal and social dimensions and internal and external orientation among the three-dimensional space of the narrative, and conducted an open-ended questionnaire about the research participants' perceptions and experiences of sports violence. After that, additional in-depth interviews were conducted during the analysis process to collect data. In particular, since the participants are active players, the possibility of discontinuation of research participation and anonymity were guaranteed in consideration of ethical issues that may arise from this. In addition, the research was conducted in consideration of the fact that the researcher had been active as a triathlete for 25 years and was also a victim. Result As a result of inductive categorization of the collected data, the perception of sports violence incidents revealed a breakdown of basic beliefs, institutional problems, concerns, and emotions. There were no negative effects on perceived internal changes, institutional problems, and indirect trauma. As for the perceived external changes, there were no negative effects and indirect trauma. Changes and others were perceived as changes. As the starting point of change, thoughts, feelings, and institutional problems about punishment were derived. As for the direction of change, concerns about secondary damage, a clear demand for change, and the need for an institutional solution were shown. Conclusion A new paradigm model was presented by arranging the responses to the three types of sports violence cases in the order of time flow.

Fexofenadine • HCl is non-sedating histamine H1 receptor antagonist that can be used for the treatment of seasonal allergic rhinitis. The objective of this study was to investigate whether the carriers of deformable liposomes can enhance the transepithelial permeability of fexofenadine • HCl across the in vitro ALI human nasal monolayer model. Characterization of this model was achieved by bioelectric measurements and morphological studies. The passage 2 and 3 of cell monolayers exhibited the TEER value of 2852482 ohm´cm2 on 11 days of seeding and maintained high TEER value for 5 days. The deformable liposome of fexofenadine • HCl was prepared with phosphatidylcholine (PC) and cholic acid using extruder method. The mean particle size was about 200 nm and the maximum entrapment efficiency of 33.0% was obtained in the formulation of 1% PC and 100 mg/ml fexofenadine • HCl. The toxicity of the deformable liposome to human nasal monolayers was evaluated by MTT assay and TEER value change. MTT assay showed that it has no toxic effect on the nasal epithelial cells in 2-hour incubation when the PC concentration was below 1%. However, deformable liposome could not enhance the transepithelial permeability (Papp) and cellular uptake of fexofenadine • HCl. In conclusion, the in vitro model could be used in nasal drug transport studies and evaluation of transepithelial permeability of formulations.

For the purpose of the therapeutic application of EMG biofeedback in the alcoholism, the authors investigated the tension-reduction hypothesis and the capability of reducing tension in alcoholics by EMG biofeedback. 21 alcoholics who were admitted to seoul National Mental Hospital from Jan. 1986 to Jun. 1986 and 21 control subjects entered for the experiment. A comparison between alcoholics and control subjects regarding frontalis muscle tension during 5 minutes of baseline recording on the first session was performed to examine the tension-reduction hypothesis indirectly. The data of muscle tension during 5 sessions of biofeedback training in both groups were analyzed to investigate the relative abilities of alcoholic subjects for neuromuscular learning, hypothesizing that alcoholics are less capable of reducing tension by nonalcoholic means than most people. The results were as follows; 1) Alcoholics(2.64±1.41μ) displayed a higher mean baseline level of frontalis muscle tension than did nonalcoholics (1.40±0.44μ) demonstrated by statistically significant difference. 2) Comparing the results of ANOVA by training condition at each session, a significant difference was found from the 3rd session in alcoholics and from the 4th session in nonalcoholics. 3) Comparing the results of t-test of mean muscle tension between types of three training conditions during each of the 5 sessions, BF(Biofeedback) group had a statistically significant difference in comparison with NF(No feedback) group or FF(False feedback) group in alcoholics and nonalcoholics. 4) The above-mentioned 2nd and 3rd results made in apparent that alcoholics can learn to reduce frontalis muscle tension by EMG biofeedback. 5) Comparison between below 2.0 μV and above 3.0 μV of baseline subgroup in alcoholics was performed, and there was a significant difference in age and duration of enforced abstinence.
