본 연구는 ‘내향성 발톱 교정에 관한 사례 고찰 연구’로서 보다 효과적인 내향성 발톱 교정 방안을 제안하고자 함에 있다. 고찰하여 분석한 결과 배민규, 윤천성(2022)은 내향성 발톱 예방 및 개선⋅교정을 목적으로 활용한 레진 젤(크랄레젤)을 활용한 내향성 발톱 교정 방법이 제품 활용 편리성, 문제점 등에서 다른 연구자들의 연구방법에 따른 문제점 등과 비교했을 때 활용 가치가 있을 것으로 판단했다. 다만 기존 다른 연구자들의 아크릴 스캅춰, Brace System, 실크, 와이어 등 제품들에 비해 교정 효과가 비교적 낮아 김경환(2022) 연구자가 내향성 발톱 교정 효과성 검증을 위해 활용했던 견인기를 함께 활용하기를 제안한다. 내향성 발톱 예방 및 재발 방지를 목적으로 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버 1회 적용을 제안하고, 내향성 발톱 개선 및 교정을 목적으로 김경환(2022) 연구자가 활용한 견인기를 활용하여 발톱을 펴준 후, 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버를 목적에 맞게 2~5회 적용하여 활용하기를 제안한다. 본 연구 자료가 내향성 발톱 질환으로부터 건강한 삶을 영위하기 위한 자료로 활용될 수 있기를 기대해 본다. As “a case study on the correction of ingrowing nail”, this study aims to suggest more effective measures for the correction of ingrowing nail. In the results of considering and analyzing it, the correction of ingrowing nail using the Resin Gel(Kralle Gel) which was used by researchers Min-Gyu Bae & Chun-Sung Youn(2022) for the purpose of preventing, improving, and correcting the ingrowing nail, seemed to be more useful than other methods used by other researchers in the aspect of convenience of product use and problem. However, compared to the products like Acrylic Sculpture, Brace System, Silk, and Wire used by other researchers, the effect on correction was relatively lower, so it is proposed to be used together with the Retractor that was used by Kyeong-Hwan Kim(2022) for verifying the effectiveness on the correction of ingrowing nail. This study suggests applying Kralle Gel Recover one time suggested by Min-Gyu Bae & Chun-Sung Youn(2002) for the purpose of prevention & recurrence prevention of ingrowing nail, unbending the nail by using the Retractor used by a researcher Kyeong-Hwan Kim(2022) for the purpose of improving/correcting the ingrowing nail, and then applying Kralle Gel Recover 2-5 times suitable for the purpose, suggested by researchers Min-Gyu Bae & Chun-Sung Youn(2022). The results of this study are expected to be utilized as the data for enjoying a healthy life from ingrowing nail disease.

The caudal subnucleus of the spinal trigeminal nucleus (medullary dorsal horn ; MDH) receives direct inputs from unmyelinated and thinly myelinated, small diameter primary afferent fibers. Thus, the MDH is implicated in the processing of nociceptive information in the orofacial region. In this study, the types and characteristics of voltage-dependent ion currents were investigated in acutely isolated MDH neurons of postnatal rats by means of the whole cell patch clamp techniques. Coronal slice (400㎛) of the trigeminal caudal subnucleus region was sequentially treated with pronase 0.2㎎/㎖. then single neurons were mechanically dissociated. Voltage-dependent sodium currents showed that the half-maximum activation potential was -41.8±1.8mV and half-maximum inactivation potential was -62.4±3.0mV. And the currents were blocked totally by application of 100nM tetrodotoxin. In a Ca^2+ free solution, low-threshold transient (I_A) and high-threshold sustained (I_K) currents were recorded. The half-maximum activation and inactivation potential of I_K were 2.5±1.9mV and -37.1±2.3mV, respectively. I_A was activated and inactivated more rapidly than I_K. The half-maximum activation and inactivation potential were -21.6±6.3mV and -84.5±5.0mV, respectively. When a 4-aminopyridine of 5mM was applied, I_A was almost totally blocked. These results reveal that MDH neurons express a variety of voltage-dependent ionic currents with distinct physiological and pharmacological properties, and they play an essential role in the transmission and modulation of sensation, especially pain, from trigeminal region.

The caudal subnuleus of the spinal trigeminal nucleus(medullary dorsal horn;MDH)is implicated in the processing of nociceptive information in the orofacial region. In the present study, whole cell patch clamp recordings were carried out on MDH neurons in brainstem slic of neonatal rats to investigate the characteristics of spontaneous excitatory postsynaptic currents(sEPSCs) and the roles of nocieptin/orphanin FQ on excitatory synaptic transmission. In the presence of atrychnine(1uM) and bicuculline(20uM), spontaneous inward currents at -70㎷ were observed. the baseline frequency, amplitude and decay time constant of sEPSCs were 2.0±0.5㎐,23.0±1.8㎀, 3.8±0.2㎳, repectively. sEPSCs were mediated by non-NMDA and NMDA receptors. The specific AMPA receptor antagonist GYKI-52466(50uM)completely blocked the non-NMDA mediated sEPSCs, indicating that they are mediated by an AMPA-preferring receptor. Perfusion of the opioid orphan receptor(ORL₁)agonist nociceptin(3uM)reduced the frequency of sEPSCs and miniature EPSCs(mEPSCs). The effects of nociceptin were blocked by the selective ORL₁receptor antagonist〔Nphe'〕nociceptin(1-13)NH_2(3uM)and were not affected by the non-specific opioid receptor antagonist naloxone(10uM). To investigate the specificity of this synaptic inhibition, we selectively astivated the nociceptive C fibers with capsaicin, which induced a strong increase in the frequency of sEPSCs. In the presence of nociceptin, the response to capsaicin was diminished. In concilsion, these results suggest that nociceptin inhibits excitatory synaptic transmission in the MDH by acting on presynaptic ORL₁receptors.

전성희,김미리혜 덕성여자대학교 학생생활연구소 1999 學生生活硏究 Vol.15 No.-

1999학년도 덕성여자대학교 신입생 및 그 가정의 제반특성을 파악하기 위하여 인적 사항, 가정환경, 입학 만족도, 대학생활, 가치관, 자신에 대한 지각 등에 관한 설문조사를 실시하였다. 총 신입생 1290명 중 응답자 1196명의 자료를 분석하여 각 문항 별로 신입생 전체는 물론 각 학부의 응답 빈도수 및 비율을 제시하였다. 되풀이 확인된 결과로는 우선, 대다수의 학생들과 수도권지역의 고등학교를 졸업하였으며 중산층 이상의 가정 출신이라는 점이다. 대부분 부모가 모두 생존해 계시고 고졸이상의 학력을 가지고 있다. 두번째, 학생들은 취업에 큰 관심을 가지고 있으며 장래 취업을 준비하기 위해 대학에 진학하였다고 답한 경우가 많았다. 이외에도 학부별 특징 등 중요한 결과들을 논의에서 요약하였다. 그리고 그 결과들이 시사하는 바를 제안하였다. Examined the characteristics of the students who entered Duksung Women's University in 1999. The total number of 1196(out of 1290) undergraduates completed an autobiographical questionnaire which inquires about demographic variables, family environment, satisfaction with the university, expectancies of a campus life, value system, and self-concept. Results show that a majority of the students were graduated from high schools located in Seoul or its vicinity. Both of their parents are alive, in the middle or higher socioeconomic groups and of high educational accomplishment (at the lowest, high school graduates). One of the replicated findings is that students are highly interested in career development. A great proportion of the students reported that they entered the college for the purpose of career preparation. Other results such as the characteristics unique to each college are also summarized and several suggestions are presented in the discussion section.

Effects of Hydrogen Peroxide on Neuronal Excitability and Synaptic Transmission in Rat Substantia Gelatinosa Neurons

Son Yong 대한구강생물학회 2007 International Journal of Oral Biology Vol.32 No.4

The superficial dorsal horn, particularly substantiagelatinosa (SG) in the spinal cord, receives inputs fromsmall-diameter primary afferents that predominantly conveynoxious sensation. Reactive oxygen species (ROS) are toxicagents that may be involved in various neurodegenerativediseases. Recent studies indicate that ROS are also involvedin persistent pain through a spinal mechanism. In thepresent study, whole cell patch clamp recordings werecarried out on SG neurons in spinal cord slice of young ratsto investigate the effects of hydrogen peroxide on neuronalexcitability and excitatory synaptic transmission. In currentclamp condition, tert-buthyl hydroperoxide (t-BuOOH), anROS donor, depolarized membrane potential of SG neuronsand increased the neuronal firing frequencies evoked bydepolarizing current pulses. When slices were pretreatedwith phenyl-N-tert-buthylnitrone (PBN) or ascorbate, ROSscavengers, t-BuOOH did not induce hyperexcitability. Involtage clamp condition, t-BuOOH increased the frequencyand amplitude of spontaneous excitatory postsynaptic currents(sEPSCs), and monosynaptically evoked excitatory postsynapticcurrents (eEPSCs) by electrical stimulation of the ipsilateraldorsal root. These data suggest that ROS generated byperipheral nerve injury can modulate the excitability of theSG neurons via pre- and postsynaptic actions.

중등학교 GIS교육과정에 관한 연구

성춘자 남서울대학교 2005 남서울대학교 논문집 Vol.11 No.1

This research analyzed the current GIS education problems and suggest to alternative solutions. The goal of GIS education at the high school focused on understanding the GIS itself and the function as the instrument in order to study. And curriculum of GIS education should be constructed step by step. Analysis of GIS goal and contents, which are perfomed based on the current four geography of high school curriculum, results in the following problems. First, GIS goal is not make a distinction among basic course, selective course, advanced course. Second, there are not boundaries in terms of degree levels among the common basic course, selective course, and advanced course. Third, it has limit that using the GIS as a practical tool because it is treated as a separate sections. With consideration of the above issues, it is desirable that GIS concept education should be started at the middle school by lowering the degree of difficulty and then increase it step by step, so that it could be completed at about 11th grade high school. Besides, "Application education" which can solve region analysis and problem should start at the lower level of high school and ends at the higher level high school. Howver, material contents should be reconstructed in order to handle the above issues.

근사적 방법에 의한 회전체의 진동해석

전상복 경인여자대학 1996 경인논집 Vol.- No.5

본 논문에서는 근사적 해석방법을 이용하여 탄성 원판이 회전체의 진동모드에 끼치는 영향을 연구하였다. 탄성 회전체의 기본적인 동 특성을 규명하기 위해 해석 대상모델은 두 개의 원판과 한 개의 축 및 두 개의 베어링으로 구성된 간단한 모델을 선택하였다. 계를 모형화함에 있어서 원심력에 의한 강성의 증가 효과, 코리오리의 힘 및 관성력을 모두 고려하였다. 수치해석의 예로서 현재 개인 컴퓨터에 사용되는 하드디스크 구동장치의 진동을 해석하였다. 특히 회전수 변화에 대한 축의 진동모드와 디스크의 진동모드의 동역학적 연성진동을 심도있게 검토하였다. 가정모드법에 근거한 근사적 방법에 의하면 복잡한 탄성 진동계의 몇 개의 저차 모드에 대해서는 그의 동특성이 정확히 해석되었다. 뿐만 아니라 유한요소해석법과 비교해 볼 때 짧은 계산시간에 각 매개변수에 대한 계의 방대한 동특성 해석이 가능하다. 따라서 본 방법은 해석의 정확도 및 경제성을 고려해 볼 때, 복잡한 구조물의 동특성에 대한 매개변수의 영향의 해석에 있어서 잘 적용될 수 있다.
