The purpose of this study was to test the effects on physiological function of hands and feet caused by the socks and gloves. This was carried out by measuring the skin temperature at 12 points on the body, the moisture under clothes and comfort sensation at 20°C and 60% RH. In these experiments, each part of skin temperature and mean skin temperature and comfort sensation were observed while wearing three kinds of socks and gloves - cotton, wool and acryl. The results obtained were as follows ; 1. The skin temperature of the body was found to be significantly changed by covering the hands and feet with socks and gloves. 2. Covering the feet the cotton socks had the highest effect of changing skin temperature of the body, especially the skin temperature of the left middle finger tip. Covering the hands wool gloves had the highest effect of changing the skin temperature. Here, the skin temperature of left lower back was found to be high. 3. At the rate of change in skin temperature, the covered feet had the highest effects on left upper chest, left abdomen and left outer upper upper arm. Covered hands had the highest effects on hands, left abdomen and left outer upper upper arm. The rate of change in skin temperature was lowest at the left toe and left middle finger tip because of being controlled in room temperature. 4. At the rate of change in mean skin temperature the cotton socks had 1% effect, that is lowest while covering the feet. The wool gloves had less than 1% effect while covering hands. 5. The moisture under the clothes being worn socks and gloves, was measured in the value of comfort. On the relative humidity of the upper chest, acryl was higher than wool or cotton. On the R.H. under the socks wool was higher than acryl and cotton. For the hands there were similar results. Generally, the R.H. at the sole and the palm was higher than the rest feet and hands. 6. The feeling of comfort which is expected to be a function of time lapse was voted in wool, cotton and acryl order. Covering the hands had a higher comfort sensation than covering the feet.

포스트 코로나19 시대 대학의 비대면 수업에 대한 운영사례와 학습자 인식 연구 ― 2020년도 중국어 수업의 동영상 녹화 강의와 실시간 화상 강의 사례를 바탕으로

장지혜 한국중문학회 2021 中國文學硏究 Vol.- No.84

2020년도 1학기는 코로나19(COVID-19)로 전국의 많은 대학들이 전면 온라인 방식으로 수업을 진행하였다. 2학기에도 상황은 크게 나아지지 않아 비대면과 대면 강의가 혼재되어 진행되었다. 코로나19는 현재도 계속되고 있으며, 많은 전문가들은 앞으로 한동안은 이러한 상태가 지속될 것이라고 전망하고 있다. 이런 점에서 앞으로 한동안은 비대면 수업이 연장될 것이라고 볼 수 있다. 게다가 몇 년 전부터 대학들은 블랜디드 러닝, 플립러닝 방식의 교수법을 연구하며 대면과 비대면이 결합 된 수업의 형태에 대해 연구하고 있었으며, 향후 적용하려고 하였다. 또한, 비대면 실시간 방식으로 활용하고 있던 ZOOM은 2학기부터는 유료로 전환할 계획이라고 한다. 이에 본 연구는 2020년도 1학기와 2학기에 실시한 중국어 수업과 관련한 비대면 수업 중 동영상 녹화 강의와 실시간 화상 강의에 대한 수업 사례와 학습자의 반응에 대한 비교를 통해 외국어 교과의 비대면 강의의 효과적인 운영과 관련해 기초자료를 제공하는 것에 의의가 있다고 하겠다. The first semester of 2020 was COVID-19, and many universities across the country conducted classes online. The situation did not improve much in the second semester, so the non-face-to-face lectures were mixed. COVID-19 is still going on, and many experts predict it will continue for some time to come. In this regard, non-face-to-face classes will be extended for some time in the future. Furthermore, several years ago, universities had been studying blend and flip-learning teaching methods to study and apply face-to-face and non-face-to-face forms of classes. Also, ZOOM, which was being used as a non-face-to-face real-time method, plans to switch to paid starting from the second semester. This study is meaningful in providing basic data on the effective operation of non-face-to-face classes in foreign language classes through comparison of video recording classes and real-time video lectures and learners’ responses.

Objective : As today obese children have increased rapidly in Korea, the interest has been much increased. The childhood obesity causes not only physical problems but also psychosocial problems and it is more difficult than that of adult to treat. That's why we started to intervene actively. Methods : In the Oriental Medical Center, several children were treated for obesity with aroma massage, low frequency wave acupuncture therapy. auricular acupuncture therapy and behavior modification and 3 children over the middle level are mentioned in this study with good results. Results : 1) After treatments, they became taller$(1.1667{\pm}0.8505cm)$. 2) After treatments, they lost their weights$(1.6333{\pm}0.7768kg)$. 3) After treatments, their BMI and OI were reduced$(1.4667{\pm}0.5774kg/m^2,\;9.8{\pm}1.7776%)$. Conclusion : We report the good results of oriental medicine on three cases of obese children over the middle level. And the further study is needed with more cases, longer duration and other tools.

하악 대구치에서 치근단 병소가 치근 이개부 감염에 미치는 영향

The purpose of the study was to investigate the influence of an endodontic infection on presence of furcation involvement in periodontally-involved mandibular molars. All first and second mandibualr molars in 45 patients were selected if at least one was root-filled or had a possible periapical radiolucency. The sample consisted of patients from a referral population at a periodotnal clinic which represented an adult population with a mean age of 47.5 years (range 31 to 63) For mandibular molars with periapical destruction at both roots, frequency of horizontal furcation depth ${\geqq}$ 3 mm was significantly more compared to teeth without periapical destruction. Mean periodontal probing depth was significantly greater at mandibular molars with periapical destruction. It is suggested that a root canal infection in periodontitis-involved molars may potentiate periodontitis progression by spreading of endodontic pathgens through patent accessory canals and dentinal tubules. In conclusion, an endodontic infection in mandibular molars was found to be associated with additional attachment loss in the furcation area, and may thus be considered to be one of several risk factors influencing the prognosis of molars in periodontitis-prone patients.

예비 초등 영어교사들의 영작문에 나타난 오류 분석

장지혜,나경희 한국중앙영어영문학회 2012 영어영문학연구 Vol.54 No.3

The purpose of this study is to investigate and analyze the writing errors of pre-service elementary education teachers at a university who are majoring in English education. In order to accomplish this, research questions were examined in particular: what types of errors were most troublesome for the subjects and how frequent they made mistakes. To answer these questions, 56 pieces of writing were collected and assessed for their writing proficiency. The results of the writing assessments indicated that the subjects made mistakes, from most to least prevalent, in the areas of language control (grammar), mechanics, vocabulary, contents and organization. Since grammar, mechanics and vocabulary are the top three categories of errors, this seems to indicate that there needs to be a greater focus on accuracy as well as fluency in the writing class. Analyzing the errors further, it was determined that first language interference was a major cause of mistakes. This was exhibited in both intra-language errors (e.g. articles, prepositions, capitalization, etc.) as well as inter-language errors (e.g. effective sentence structure, punctuation, agreement, tense, number, etc.). All of this points to the need for a more systematic methodology for improving the writing skills of these subjects. It is important for teachers to consider the most common errors that students make and teach with these in mind. Knowledge of these errors can be used to help prepare lesson plans and teaching materials, as well as choose appropriate textbooks. Additionally, given the intra-language errors that were prevalent, relevant grammar and authentic materials are needed in the classroom to give the students appropriate input.

장지혜,김유철,김광수 대한안과학회 2009 대한안과학회지 Vol.50 No.6

Purpose: To evaluate clinical analyses & risk factors for retinal detachment after silicone oil removal in the eyes with completely stable retinal state. Method: The authors retrospectively analyzed the clinical diagnosis, timing of retinal detachment, operative record, and final anatomic success of 10 consecutive eyes with retinal detachment after silicone oil removal. Results: The retinal detachment group after silicone oil removal consisted of 3 eyes with proliferative vitreoretinopathy, 3 eyes with proliferative diabetic retinopathy, 3 eyes with the retinal detachment with macular hole and 1 eye with traumatic rhegmatogenous retinal detachment. Retinal detachment occurred from 1 to 17 weeks after the silicon oil removal surgery. The retinal detachments were associated with reopening of old breaks (5 eyes), new retinal breaks (3 eyes), vitreoretinal tractions (2 eyes). The retina was completely or partially reaatached after additional vitreoretinal surgery in 9 eyes, but total retinal detachment occurred in 1 eye due to reattachment operation rejection. Conclusions: The retinal break with remained vitreous traction and the proliferative membrane appeared to be an important factor in retinal detachments after silicone oil removal. Therefore, potential retinal breaks and complete removal of vitreous and tractional force during intraocular surgery should be considered. 목적: 실리콘기름 제거 후 망막박리가 발생한 10안을 대상으로 실리콘기름 제거 전 후의 임상양상 및 망막박리에 미치는 영향들에 대해 알아보고자 하였다. 대상과 방법: 실리콘기름 제거 전 망막의 완전 유착이 있다가 실리콘기름 제거술을 받고 망막박리가 발생한 10안을 대상으로 실리콘기름 주입 전 진단명, 실리콘기름 제거 후 재박리 시기 및 원인, 경과 상태 등을 후향적으로 분석하였다. 결과: 증식유리체망막병증 3안, 당뇨망막병증 3안, 황반원공을 동반한 망막박리 3안, 외상성 열공망막박리 1안에서 실리콘 제거 후 망막박리가 발생하였다. 망막 재박리는 실리콘기름 제거 후 1주에서 17주 후에 발생하였고, 망막박리 10안 중 5안은 기존의 열공, 3안 은 새로운 열공을 통해, 열공이 관찰되지 않던 2안은 증식유리체망막병증에 의한 견인력에 의해 망막박리가 발생하였다. 9안에서는 해부학적 성공을 거두었으나, 1안에서는 전체망막박리로 실패하였다. 결론: 실리콘기름 제거 후 발생한 망막박리는 기존의 열공 및 새로운 열공, 증식성 섬유세포에 의한 견인막과 관련이 있으므로 실리콘 기름 제거하는 과정에서 열공의 완전폐쇄에 힘쓰고 섬유혈관성 막 제거를 철저히 하여야 한다.

綿織物의 構成特性과 冷溫感과의 相關性에 관한 硏究(Ⅰ) : 相對濕度 65%下에서 at 65% Relative Humidity

장지혜 한국의류학회 1990 한국의류학회지 Vol.14 No.2

The purpose of this study is to experimentally analyze the relationship between structural characteristics of cotton fabrics and their cool-and-warm felling in order to develop more comfortable fabrics. Comfort in textile products has been emphasized as consumers preferred performance to fashion of clothing. Thermal comfort of clothing is a- basic parameter of the comfort sensation which is usually represented by the cool-and-warm feeling felt by human skin. Cloo-and-warm feeling is perceived by the heat flux which transfers heat energy stored in an object to skin. We feel warm (cool) if the temperature of nerve extremity in skin ascends (descends). As cool-and-warm feeling determines the comfort sensation of clothing, it is important to develop new comfort fabrics. Although considerable works have been made on the body, clothing, and environment, there has been no research study on the structural characteristics of fabrics and their cool-and warm feeling. Cool-and-warm feeling is closely related to the transient heat transfer property. This research study used the cotton fabrics manufactured in Korea as sample and measured q_max value with thermal property measuring instrument (Thermo-Labo Ⅱ type). q_max values estimated by polynomial regression equation were compared with those observed in this study. This study also identified the structural parameters of cotton fabrics for a specific range of qmax values. The findings of this study can be summarized as follows: 1) As the thickness, porosity and air permeability of cotton fabrics increase, q_max, value decreases. 2) As the fabric count and over factor of cotton fabrics increase, q_max value also increases. 3) q_max values have been estimated by simple and polynomial regression equations developed in this study. Regression curves which have been plotted by polynomial regresson equations also provided with the range of structural parameters for a specific range of q_max, values of cotton fabrics. This study would be significant in that it has identified the structural parameters for the cool-and-warm feeling of cotton fabric at 65% relative humidity.
