정종현,김성식,손우성,박수병 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.2

본 연구는 중안면 함몰이 있는 골격성 III급 부정교합자의 중안면의 형태를 정상 표본과 비교하고, 악교정수술에 의하여 연조직이 어떤 변화를 보이는지를 알아보기 위하여 시행하였다. 골격성 III급 부정교합으로 진단받고 상악 전진술과 하악 후퇴술을 시행받은 환자 34명 (남자:15명, 여자:19명)을 대상으로 수술 전후 측모 두부방사선 계측사진을 분석하였다. 골격성 III급 부정교합자의 중안면의 경조직 계측치 S'-Or, Or⊥NA, S'Or/SN, ∠SNOr에서 남녀 모두에서 정상 교합자와 큰 차이가 있었다. 상악골이 평균 5.03 mm 전방이동 될 때 연조직 Orbitale는 2.26 mm 전방으로 이동하였으며 상관계수는 0.599였다(p < 0.05). 상악 평면각의 변화(시계방향으로 회전)와 상악골의 수직 이동은 연조직 Orbitale의 전방이동과 유의성있는 상관관계가 없었다. 상악골 전방이동에 대한 연조직 Orbitale와 Subnasale의 전방이동 비율은 각각 43.57%, 81.54%였다. 이상의 결과에서 중안면 함몰이 있는 환자는 상악골 전방이동시 상순과 비부 외에도 연조직 Orbitale를 포함한 중안면 연조직이 전방으로 이동하지만, 상악골의 회전이동 및 수직이동에 대해서는 연조직의 변화량이 적었다는 것을 알 수 있었다. 이는 상악골의 수술에 따른 중안면 함몰의 해소를 예측하는 데 도움이 될 것이다. Purpose: The first objective of this study was to compare the upper midface morpholgy, focusing on the soft tissues, between skeletal Class III maloccusion patients with midfacial depression and the norm. The second objective was to estimate and analyze the change in the upper midface soft tissues following surgical correction with maxillary advancement by Lefort I osteotomy and mandibular setback by bilateral sagittal split osteotomy (BSSRO). Methods: The samples consisted of 34 adult patients (15 males and 12 females) with an average age of 21 years, who had severe anteroposterior discrepancy with midfacial depression. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of simultaneous Lefort I osteotomy and BSSRO. Results: The correlation coefficient between changes in maxillary advancement and changes in Or' (soft tissue orbitale) was 0.599 (P < 0.05). Change in maxillary plane angle and vertical change of the maxilla were not correlated with the change in Or' (P < 0.05). The ratio of soft tissue change in Or' to maxillary advancement was 43.57 %, and 81.54 % in Sn. Regression equations between maxillary movement and Or' were devised. The r² value was 0.476. Conclusions: The majority of measurements in the upper midface in skeletal Class III maloccusions when compared to the norm, showed significant differences. In Class III malocclusion with midfacial depression, maxillary advancement produces soft tissue change in the upper midface.

The purpose of this study is the approach to I.I.C.P. centered on the meaning of consciousness disorder and the pathological aspect of Kwul(lose consciousness ; faint, fall, into a coma). The meaning of consciouseness disorder and apoplexy is evidently involved the definition of Kwul. 1. It is found that the etymological interpreation on Kwul which the energy rises back to go through blocked space and the meaning interpretation of regarding Kwul as apoplexy with medical viewpoint, are related with consciousness disorder and motor distrubance in IICP in the aspect of the rise fo Kwul and the abnormal rising of vital energy and blood, In addition, the overall of meaning of Kwul is showed in table <1-1> by reference to doctors of many generations. 2. The pathology of Kwul includes abnormal rising, sthenia-syndrome in the upper part and asthenia in the lower, the origin of Kwul, the lower, looking like Yin by too sthenic Yang and looking like Yang by too sthenic Yin. The headache, vomiting, papilledema, paralsis of nervi craniales, coma, blood pressure rising, tachycardia by I.I.C.P can be regarded as a conception of trouble of vitalenergy, sthenia-syndrome of Kwul. The pulse pressure, brachycardia, bradypnea can be regarded as the conception of looking like Yin by too sthenic Yang. 3. In the emergency of Kwul, the abnormal ternimal reversion of the Kwulyin channel, Kuyang channel, and three Yins are realted with the phenomenon in I.I.C.P. It is considered that the reverse movement of materials, I,I.C.P. can be closely observed by giving meaning on the meridian of Kwul in Somunkwulron. And the content of phrases of Naelyung which includes consciousness disorder refered in the chapter of Kwul, is compared with I.I.C.P. 4, The followings should be considered ; examination of optic symptom and abnormal posture in cerebral herniation ; understanding and working out counterplans of factors and symptoms of consciousness disorder by the observation of vital sign, check of general stages, neurologic inverstigation, clinical diagnosis, and subsidiary diagnosis ; application of morphological change of opinion ; addtion of the conception of demonstration centered on Yunkyoungm, Samyinkwulruk, asthenia and thenia of healthy energy in oriental medicine. 5. The similarity of Kwul and I.I.C.P. can be found from etilolgy and pathotenic factor. The similarity is clearly found by investigation of etiology, pathotenic factor, symptoms and thrapy of Kwul, disease symptom and other symptoms.

This paper presents an LQR design method for nonlinear multi-variable systems using fuzzy model-based gain scheduling. For the design of LQR, the nonlinear system is first represented by Takagi- Sugeno’s(T-S) fuzzy model. In T-S fuzzy model, nonlinear system is represented by a set of linear models, and the stability of control system is analyzed. The proposed gain scheduling LQR is applied to the nonlinear inverted pendulum system, and it is illustrated by simulations that the control performance of the proposed method is better than the existing fuzzy optimal method.

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

규범행위에 있어서 죄책감과 수치심의 역할 : 이타 및 일탈행동의 예를 중심으로 The Case of Altruistic and Deviant Behavior

전신현,이성식 高麗大學校 社會學硏究會 1995 사회와문화 Vol.9 No.1

본 연구는 감정이 인간의 행동을 설명하는 데 있어 중요한 요인이 되는지에 관심을 갖는다. 특히 죄책감과 수치심에 초점을 두어 이들 감정이 도덕적 규범행동의 중요한 동기요인이 되는지를 이타행위와 일탈행위에 적용하여 살펴본다. 특히 본 연구는 죄책감과 수치심은 그 특성의 차이로 인하여 그 형성과정은 다른지 그리고 한국 사회의 특성과 관련하여 죄책감과 수치심간에는 이타 및 일탈행위를 설명하는 데 있어서 그 설명력의 차이가 존재하는지에 관심을 갖는다. 서울시 남녀 고등학생 789명을 대상으로 한 경험적 연구의 결과에서는 이타행위와 일탈행위에 있어 죄책감은 타자의 기대보다는 개인규범에 의해 보다 영향을 받으며, 수치심은 개인규범보다는 타자의 기대에 의해 보다 영향을 받는다는 것으로 나타났다. 또한 죄책감이 이타 및 일탈행위에는 영향을 주지 못하는 반면 수치심은 이러한 행위에 유의미한 영향력을 갖는다는 것을 보여주었다. 이는 개인규범보다는 타자와의 관계를 중시하는 한국사회의 문화적 특성에서 비롯된 것이라 볼 수 있다.

免疫細胞 및 腫瘍細胞에 미치는 丹蔘의 效果

鄭鉉雨,姜聲度,陳千植 대한동의병리학회 1998 동의생리병리학회지 Vol.12 No.2

免疫은 人體內에서 어떤 요인으로 인해서든지 異物이 침입하거나 變異細胞가 발생하면 Immune system이 관여하여 異物은 물론 새로이 발생된 變異細胞를 非自己로 인식하여 처리하는 能力을 발휘함으로써 個體의 恒常性을 維持하려는 현상을 말하고, 이러한 免疫作用에 관여하는 細胞는 特異性 免疫에 관여하는 免疫細胞外에도 Macrophage, NK cell, 수지상세포 및 랑게르한스 세포등을 들 수 있으며, 腫瘍은 組織이 自律的으로 過剩 成長한 것으로 이것은 개체에 대해서 意義가 없거나 이롭지 않을뿐더러 正常組織에 대해서 破壞的인 작용을 하는 것으로 東醫學에서는 正氣補養 및 補血을 爲主로하면서 破積·活血·解鬱·行氣등의 治法들을 兼用하고 있고, 西醫學에서는 手術療法, 放射線療法, 化學療法 및 免疫療法과 遺傳子療法등을 使用하나 癌腫에 따른 感受性과 治療 後의 經過 그리고 副作用이 각기 다르고, 또 이에 따른 많은 문제점들을 안고 있는 것이다. 癌細胞의 增殖을 抑制하는 方法에는 necrosis와 apoptosis가 있는데, apoptosis란 necrosis(세포괴사)와는 대조되는 용어로 초기에 핵의 응축, 세포질의 응축, 수포상의 세포돌기 형성등이 관찰되고, 生體內의 apoptosis는 腫瘍發生時 macrophage에서 분비되는 각종 cytokine에 의해 일어나거나 cytotoxic T-lymphocyte에 의해 일어나는 것으로 抗癌劑들의 부작용 및 tumor regression과 관계가 있는 것으로 알려져 있다. Nitric oxide(NO)는 cNOS와 iNOS 2 종류가 있으며 cNOS는 vascular endothelium 및 brain에서, iNOS는 활성화된 macrophage 및 여러 세포에서 발견되었다. Macrophage가 생산하는 NO는 生體內에서 癌細胞를 공격하여 傷害시키는 癌 免疫의 effector로서 그 역할을 하고 있고, 癌細胞의 增殖을 抑制한다. 丹蔘은 活血祛瘀시키면서 凉血安神시기 때문에 産後瘀滯腹痛·경폐징하·心腹刺痛과 熱毒으로 인한 癰腫·瘡瘍등에 利用되고, 最近에는 肝臟腫大와 動脈硬化症, 그리고 食道癌·胸腺癌 및 腹腔腫瘍에도 사용하고 있는 藥物로 本 硏究에서는 丹蔘에 대한 癌細胞 增殖 抑制作用과 免疫細胞 增强作用을 관찰한 결과 丹蔘은 In vitro上에서 A431 cell line과 KHOS-NP cell line의 增殖을 抑制하지는 않았지만 마우스 胸腺 및 脾臟細胞의 增殖을 活性化시켰다. 그러나 腹腔 macrophage에서 생성되는 NO는 丹蔘에 의해 in vitro상에서 억제되었고 in vivo상에서도 對照群과 큰 차이를 보이지 않았는데, 이는 丹蔘이 腹腔 macrophage의 活性化보다는 T-lymphocytes나 splenocytes의 增殖에 작용하는 것으로 思料된다. To investigate effect of water extract of Salviae Radix on human cancer cell-lines and immunocytes, this research estimated the proliferation of A431 cell lines, KHOS-NP cell lines, mouse thymocytes and mouse splenocytes, nitric oxide(NO) production from peritoneal macrophages, apoptosis and sub-population of mouse thymocytes. The result were obtained as follows ; 1. Salviae Radix wasn't effect the proliferation of A431 cell lines and KHOS-NP cell lines. 2. Salviae Radix was accelerate the proliferation of mouse thymocytes and splenocytes. 3. Salviae Radix was not accelerate the NO production from peritoneal macrophages in vitro. 4. Salviae Radix was inhibited the NO production from peritoneal macrophages in vivo. 5. Salviae Radix was accelerate the induction of apoptosis and sub-population of the mouse thymocytes.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.
