The purpose of this study was to assess the soft tissue changes using twenty skeletal class III malocclusion patients who treated with bimaxillary surgery for the correction of dentofacial deformities. Patients were divided into two groups. One was impaction and advancement of maxilla with mandibular set-back (Group 1), the other was downward and advancement of maxilla with mandibular set-back (Group 2). Preoperative and postoperative one year cephalometric data were analyzed and compared. Results obtained were as follows: 1. The ratio of horizontal changes of soft tissue to hard tissue at Nt to ANS, Ls to UI, Li to LI, sPog to Pog were 1:0.60, 1:0.79, 1:0.47, 1:0.63 in group 1 respectively, and 1:0.59, 1:0.48, 1:0.83, 1:1.09 in group 2 respectively. Soft tissue changes were highly predictable at the upper lip, lower lip, and chin area. 2. The ratio of vertical changes of soft tissue to hard tissue at Nt to ANS, Li to LI were 1:0.72, 1:0.06 in group 1, and others showed no statistically significant difference. 3. The ratio of horizontal changes of Ls to hard tissue movements at LI(h) was 1:-0.82 in group 1 and at UI(h), LI(h) were 1:0.48, 1:0.01 in group 2. These ratios of group 1 were greater than those of group 2. 4. The direction of horizontal change of Li was the same as that of hard tissue change. The ratio of horizontal changes of Li to LI was 1:0.47 in group 1 and others showed no statistically significant difference. 5. The changes of upper lip thickness and length were -1.6mm, -1.4mm in group 1, and -1mm, -2.7mm in group 2. 6. The ratios of thickness of upper lip to ANS, UI, LI were 1:-0.83, 1:-0.37, 1:0.11 in group 1. There was similar trend in group 2, and there were no statistically significant difference. These results suggest that prediction of changes in soft tissue of upper lip, lower lip, and chin were 79%, 47%, and 63% in group 1, and 48%, 83%, and 109% in group 2. There was a tendency to decrease in thickness and increase in length of the upper lip.

표피 전기 자극에 의한 전정 신경의 반응:내이 전기 자극에 의한 반응과의 비교

박홍주 대한이비인후과학회 2005 대한이비인후과학회지 두경부외과학 Vol.48 No.7

Background and Objectives:Electrical stimulation has been used for several vestibular tests, such as galvanic body sway tests and galvanic evoked myogenic responses. In these tests, small amplitude galvanic currents are delivered transcuta-neously to the vestibular afferents. It is noted, however, there has not been any reports concerning the difference between the afferent-responses to transcutaneous and perilymphatic galvanic stimulations. Subjects and Method:We used anesthetized chinchillas and made extracellular recordings from vestibular afferents. Galvanic currents were applied transcutaneously and perilymphatically, and we compared the responses of vestibular afferents at each condition. Results:Irregular afferents had characteristically large galvanic responses and regular afferents had characteristically small responses. For regularly discharging afferents, the mean galvanic sensitivities to anodal/cathodal currents were 0.22±0.23/0.23±0.17 spikes·s-1/μA (n=17), and 1.64±2.18/1.88±2.07 spikes·s-1/ μA for irregularly discharging afferents (n=11). The estimated amplitude of perilymphatic galvanic stimulus, which showed the same changes of the resting rates by transcutaneous galvanic stimulation using 1 mA, were 65.0/66.0 μA for regularly and irregularly discharging afferents, respectively. Conclusion:These findings suggest that transcutaneous galvanic stimulation affectsirregular afferents more than regular afferents perilymphatic galvanic stimulation. And more than 1.54 mA amplitude of transcutaneous galvanic stimulation is needed to ablate irregularly discharging afferents functionally.

Purpose: This study is to investigate the relationship between clinical practice stress, resilience and depression in nursing students. Methods: The subjects of this study were 3rd and 4th year students in two nursing school. The data collected from June 23rd to July 15th, 2019. Data were analyzed by frequency and percentage, mean and standard deviation, t-test, ANOVA and Pearson correlation coefficients. Results: The mean of clinical practice stress, resilience, and depression were 3.01±0.52, 3.56±0.42, and 2.20±0.61 respectively. Clinical practice stress showed a significantly correlated both with resilience (r=-.18, p=.002) and depression (r=.31, p<.001). Resilience of nursing students was significantly negatively correlated with depression (r=-.36, p<.001). Conclusion: According to the results of this study, it is considered that it is necessary to develop a variety of intervention programs that promote resilience to reduce clinical practice stress and depression in nursing college students.

중이내 젠타마이신 일회성 투여 후 전정 신경의 반응 변화

Background and Objectives:Aminoglycoside antibiotics are toxic to hair cells of the inner ear. Recently, intratympanic gentamicininjection is widely accepted as a treatment modality for Meniere’s disease. Subjects and Method:We treated anesthetizedchinchillas with one injection of gentamicin into the middle ear and made extracellular recordings from afferents afterthree to four weeks. Results:The spontaneous firing rate of regular and irregular afferents was lower (p<0.05) on the treatedside than on the untreated side. The relative proportions of regular, intermediate, and irregular afferents did not change aftertreatment. The majority of the treated afferents did not significantly respond to rotation, and those that did respond had abnormallylow levels of sensitivity. Sensitivity to externally applied galvanic currents was unaffected. Conclusion:These findingssuggest that a single intratympanic gentamicin injection preserves enough hair cell synaptic activity to drive the spontaneousactivity of vestibular afferents, and does not damage the afferent spike initiation zones.

성조숙 아동의 성성숙 정도에 따른 신체상, 성숙불안

박홍주,김남희 사단법인 인문사회과학기술융합학회 2016 예술인문사회융합멀티미디어논문지 Vol.6 No.5

The purpose of this study was to investigate the sexual maturity rating, body image, and anxiety levels among female elementary school students who receive sex hormone therapy for precocious puberty. The present study is a descriptive study. Data were collected from August 4th to August 30th, 2014. A sample of 186 children receiving sex hormone therapy for precocious puberty was recruited from a pediatric endocrine clinic at a general hospital in B city. In the body image, statistically significant differences occurred depending on the grade(year) in school, father's body shape, and concerns. As for the levels of anxiety, types of family structures, father's body shape, the period of hormone therapy done, concerns, and the time to go to bed showed statistically significant differences. In S. Korea, there have been no great deal of studies on children receiving hormone therapy for precocious puberty. Thus, this study is exceptionally meaningful by approaching to evaluate different aspects of the issues with early puberty. 본 연구는 성조숙증 진단을 받고 호르몬 요법을 시행 중인 초등학생의 성성숙과 신체상 및 성숙불안 정도와 이들 간의 관계를 알아보기 위한 서술적 조사이다. 소아내분비 세부전문의에 의해 성조숙증으로 진단받고 호르몬 억제요법을 시행 중이며 호르몬주사 사용기간이 3개월부터 2년 이상인 아동으로 4주에 한번 씩 성조숙 억제호르몬 주사를 맞기 위해 방문하고 있는 아동 186명을 대상으로 하였다. 자료수집기간은 2014년 8월 4일에서 8월 30일까지였다. 일반적 특성에 따른 가슴 발달 단계는 학년, 호르몬 주사기간, 병원 동행에서, 성장속도는 학년, 호르몬 주사기간에서 통계적으로 유의하게 나타났으며, 신체상은 학년, 아빠 체형 및 걱정거리에서, 불안은 가족구조, 아빠체형, 호르몬주사 기간, 걱정거리, 잠자는 시간대에서 통계적으로 유의하게 나타났다. 성성숙에 따른 신체상은 가슴발달과 성성숙에 따른 불안은 가슴발달과 통계적으로 유의한 차이가 있었다. 부모와 담임교사 및 아동들에게 조기 사춘기 아동들의 심리사회적 측면과 신체상의 발달에 관한 긍정적인 변화와 효과적인 성장발달을 알리는 교육 및 간호중재를 위한 활발한 연구가 이루어질 필요가 절실하다고 하겠다.
