상대적 운동 강도가 혈청 IL-2, IL-6 농도에 미치는 효과
박성태 한국사회체육학회 2005 한국사회체육학회지 Vol.0 No.23
@@@Exercise is of benefit to many aspects of health, but exhaustive exercise above specific intensity is related to the exercise-induced inflammation response. However, it is obscure how the intensity of exercise cause to increase the response. Therefore, the purpose of this study is to examine the effects of different exercise intensities on the level of cytokines, which is factor to induce the inflammation response. Particularly, we intend to apply the same exercise volumes to examine only the pure effects of exercise intensity. 8 healthy young males participated in two trials. At each trial, subjects ran on the treadmill at the respective intensities corresponding to 50% and 85% of VO2max. They exercised for different duration so that energy expenditure was equal to all subjects. The order of the trials was randomized and separated by one week. Blood was obtained at rest, immediately after exercise, and at 90 min after exercise to measure IL-2 and IL-6 level. Serum IL-6 level increased significantly immediately after exercise more than rest to submaximal exercise at 85% O2max(p<.05). In comparison between two exercise intensities, IL-6 level at the 85% intensity was significantly higher than at the 50% intensity immediately after exercise and recovery 90 minutes(p<.05). No significant change was seen in exercise-induced Serum IL-2 level. In conclusion, this study demonstrate that Exercise-induced IL-6 were affected by exercise intensity as well as exercise time and in the higher exercise intensity, there were the increased IL-6 level.

Craniopharyngioma with Intratumoral Hemorrhage and Superficial Siderosis
박성태,Jeong Hee Oh,Hyun Kyung Lim 대한자기공명의과학회 2018 Investigative Magnetic Resonance Imaging Vol.22 No.4
Superficial siderosis of the central nervous system (CNS) is a progressive and debilitating neurological disease manifesting sensorineural hearing loss, cerebellar ataxia, and pyramidal tract signs. Chronic extravasation of blood into the subarachnoid space results in the accumulation of hemoglobin derivate in the subpial layer of the CNS, which is toxic to the neural tissues. Craniopharyngioma is a benign third ventricle tumor, which rarely presents with tumor bleeding. We report a rare case of superficial siderosis associated with craniopharyngioma with intratumoral hemorrhage in a patient with no history of prior trauma or CNS surgery.

Purpose : To evaluate the efficacy and safety of preoperative embolization of intrancranial meningioma.Materials and Methods : We retrospectively reviewed intrancranial meningioma patients (n=37) who underwent preoperative embolization. They were categorized into two groups, skull base lesions (n=22) and non-skull base lesions (n=15), according to tumor location. In addition, embolization results were classified by comparison between pre-and post-embolization angiography as complete (residual tumor staining<10 or 30 %) or incomplete(residual tumor staining$\geq$10 or 30%). In each group, estimated blood loss (EBL) was estimated by amount of intra operative transfusion with pre- and post-operative hemoglobin level. Tumor resectability was evaluated by follow-up computed tomography. New symptoms occurring within 24 hours of embolization were considered to be those associated with embolization ; symptoms improved by conservative treatment were regarded as mild, while those resulting in new deficits were considered severe. Results : In the group with skull base lesions (n=22), complete embolization with the criteria of residual tumor staining of less than 30% was performed in 14 patients(EBL=1770ml ; complete surgical removal in nine patients and incomplete removal four). Incomplete embolization was performed in eight patients (EBL=3210ml; complete and incomplete removal each in four patients). In the group with non-skull base lesions, complete embolization with the criteria of residual tumor staining of less than 10% was performed in five patients (EBL=970ml) and incomplete embolization in ten (EBL=2260ml). Complete tumor removal was possible in this group regardless of the completeness of preoperative tumor embolization. In a case of intraventricular meningioma (3%), intratumoral hemorrage occurred on the day following embolization. Other mild post-embolization complications occurred in three cases (8%). Conclusion : Preoperative embolization can be an effective and safe procedure for meningioma and may reduce intraoperative blood loss. Its effectiveness may depend on tumor location and the degree of embolization, though the procedure seems to be helpful for lseions at the skull base.

日韓の母語場面と接触場面における重なりと相槌 ―話者交替を中心として―
朴成泰 한국일본어문학회 2021 日本語文學 Vol.90 No.-
본 연구는 일본어와 한국어의 자연발화 데이터를 이용하여 담화의 중복현상과 화자 교체 및 맞장구와의 관계를 조사했다. 구체적으로는 한국어와 일본어의 모어화자, 접촉 장면, 대면, 비대면으로 분류하여 중복현상에 의한 화자 교체 및 중복현상과 맞장구 간의 연관성을 분석하기 위하여 교차분석을 실시하였다. 그 결과는 아래와 같다. 1) 모어화자인 일본인과 한국인은 대화방식이 대면 또는 비대면 방식이냐에 따라 전체 중복수 수치의 차이가 있는 것으로 나타났다. 2) 모어화자에 따라 맞장구 수치의 차이가 있는 것으로 밝혀졌다. 3) 모어화자에 따라 화자교체의 수치 차이가 있는 것으로 판명되었다. 4) 모어화자인 일본인과 한국인은 모국어를 사용할 때와 외국어를 사용할 때 전체 중복수치의 차이가 있음을 확인했다. 5) 모어 또는 외국어를 사용할 때 모어화자와 따라 대화방식의 전체 중복의 수치의 차이가 존재하지 않는 것으로 나타났다. 6) 모어를 사용하는 경우는 모어화자와 맞장구 간의 차이가 존재하지 않지만, 외국어를 사용하는 경우 모어화자와 맞장구 간의 수치의 차이가 존재한다는 사실이 확인되었다. 7)모어와 외국어를 사용하는 경우 모어화자와 화자 교체 수치에 차이가 있음을 알 수 있었다. In this study, I investigated the relationship between discourse overlap phenomena and speaker turn taking and back-channel use based on natural utterance data in Japanese and Korean. Specifically, I conducted a cross-analysis to examine the correlation between speaker turn taking and overlap back-channels based on utterances in native Japanese and Korean situations, utterances in contact situations, and face-to-face/non-face-to-face utterances. The results are as follows. 1) There is a difference in the overall overlap value for both Japanese and Korean native speakers depending on whether the conversation method is face-to-face or non-face-to-face. 2) There is a difference in the back-channel value by native speaker. 3) There is a difference in speaker turn-taking value by native speaker. 4) There is a difference in the overall overlap value between Japanese and Korean native speakers when using their native language versus a foreign language. 5) Whether using a native or foreign language, no difference was found in the overall overlap value of the conversation method by native speaker. 6) There is a difference by native speaker in the back-channel value when using a foreign language, but no such difference is present when using the mother tongue. 7) Whether using the mother tongue or a foreign language, there is a difference by mother tongue in the value of the speaker’s turn taking.
