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.

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.

This study was designed to evaluate the effect of intermittent electrical stimulation on atrophied masseter muscle in the rat(230-250g). Growing Sprague-Dawley rats(80g) were assigned to either a control(CONT), a soft dieted(SOFT), or a soft dieted plus intermittent electrical stimulation(SOFT-ES) group. CONT group was continued to receive an ordinary hard rat diet and SOFT group received an ordinary diet in a ground form, mixed with water in a proportion of 2:5, for 6 weeks. After 6 weeks of soft diet feeding in SOFT group, mechanical properties of contraction in the masseter muscle were measured by means of isometric force transducer and then electrodes were implanted to the masseter muscle for intermittent electrical stimulation(SOFT-ES group). In SOFT-ES group, electrical stimulation was applied directly to the masseter muscle for 2 weeks at supramaximal intensity, 0.3ms, 20Hz for 15 minutes every 6 hours. After electrical stimulation for 2 weeks, mechanical properties and fatigue tendency of the masseter muscle were observed. The results were as follows. 1. Twitch tension was no significant difference according to the mandibular position, however, tetanic tension at 11㎜ interincisal distance was larger than at 7㎜. 2. In SOFT group, tetanic tension and contraction time were decreased, and fatigue tendency was increased compared with the control group. 3. In SOFT-ES group, tetanic tension was increased and fatigue tendency was decresed compared with the soft dieted group, however, all mechanical properties of muscle contraction were similiar to those of the control group. 4. Effects of electrical stimulation in atrophied muscle were more prominant in tension-related properties than speed-related properties. These data suggest that intermittent electrical stimulation may be useful in prevention and treatment of muscle atrophy.

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.

The aim of this thesis is comparative study between <Yeowachon> and <FengShenYanYi>. It is expected that the comparative study is to clear the homogeneity and heterogeneity of theme and materials in these works. <Yeowachon> is very important work to understand the history of novels specially before the early 18th century. And <FengShenYanYi> is a representative historical novel with the character of mythical heroes. These works have lots of same sides the title, characters, plots and the method of descriptions. And more, these works have the similar theme which establishes order in the world of chaos. These facts mean that these works are published at the similar generation of novel history. Even though there are lots of similar sides between them, we can't conclude that <Yeswachon> are created in similitude of <FengShenYanYi>. We can't sure the influences of <FengShenYanYi>. And more important, there are many different sides between them. For examples, <Yeswachon> not only has characteristics of historical novels but the characteristic of dream novels. And the ground of ideology, the aesthetic sense and characters are different from those of <FengShenYanYi>. Like these, similar and different sides between them are originated from the developments of novel history of each countries. The novel histories of each country developed very similar, and also they have different literary hereditaments. So obviously, they have no relations but have lots of similar sides.

Background: Although dental implantation has become widespread and acceptable treatment for dental prosthodontics, maxillary posterior jaw region is often complicated by the pneumatization of the maxillary sinus and physiological resorption of the alveolar bone. When this occurs, the residual bone between the floor of the sinus and the crestal ridge is inadequate for the placement of implants. The sinus elevation procedure provides a way to increase the amount of available bone and to allow the placement of longer implants. Materials & methods: We studied 11 patients requiring the implant placements and the maxillary sinus elevation simultaneously from 1996 to 2003 in our clinic. Nine patients were males and two patients were females, aged from 39 to 72(mean=51.6). Four patients had medical compromised states; angina pectoris, diabetes, hypertension, hepatitis. Patients didn't show any pathologic findings clinically or radiographically. We studied the success and survival rate of implants, factors increasing the osseointegrating capacity of implants. Results: The success rate of osseointegration of implants was 93%. At least 6 months after loading on implants, the survival rate of implants was 78.5%. Autogenous bone graft and adequate residual bone height(>6mm) increased survival rate of implants. Conclusion: Successful implant placement with maxillary sinus elevation mainly depends on sufficient residual bone height, healthy maxillary sinus, autogenous bone graft.

흰쥐 삼차신경 척수감각핵의 미측소핵 세포의 전압의존성 소디움통로와 포타슘통로에 대한 전기생리학적 연구

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.
