The present study was performed to evaluate the effect of EDTA on diseased root surfaces with regard to the removal of the smear layer, exposure of dentinal tubule openings, and demineralization of the peritubular dentin. 20 periodontally involved single rooted teeth were used. After scaling and root planing, root conditioning was carried out with 3%, 17%, and 24% EDTA solution for 20 sec., 3 min., and 5 min. respectively. Then, the specimens were rinsed with tap water for 5 min. and processed for scanning electron microscopic observation. The following results were obtained. 1. In control group which was conditioned with cotton pellets soaked with saline for 3 min., the surface showed an amorphous irregular coating. The tubule orifices seemed to be com-pressed in the direction of the curette strokes. 2. In test group which was conditioned with EDTA solution, the number of opening dentinal tubules and the extent of the dentinal tubule opening increased with time irrespective of the concentration of EDTA solution. 3. In the group which was conditioned with EDTA solution for 20 sec., the smear layer was not completely removed. 4. If the time of root conditioning is above 3 min., collagen-like fibers covering the circum tubular dentin surface were shown even in the group which was conditioned with 3% EDTA solution. In conclusion, EDTA solution was a very effective root conditioning agent like low pH root conditioning agents which had various disadvantages. Therefore, using EDTA solution, more successful periodontal regeneration could be obtained.

Purpose The cold hypersensitivity is a subjective symptom and it is very difficult to evaluate the severity. It is possible to detect cold hypersensitivity by measuring the skin temperature on DITI, but there is limitation only using DITI to find the objective grade of the symptom. To set a new objective standard for the diagnosis of cold hypersensitivity, we examined the relationship between the Visual Analogue Scale (VAS) score for the cold hypersensitivity and the change of skin temperature on hands by cold stress test Method 23 patients with symptom of cold hypersensitivity were participated as subjects who visited the women medical center of Kangnam Kyunghee Korean Hospital, Kyung Hee Univ. from May 1, 2002 to August 31, 2002. There were all carefully examined to rule out other disease such as obesity, skin diseases, spinal nerve lesions and external wounds. Thermographic observations for this study were made using DITI. We performed cold stress test three times to compare with the results from thermographic observations by DITI: first, after 15 minutes-resting, second, right after 1 minutes soak in $20^{\circ}C$ water, the third for last, 10 minutes after the soak. VAS score was chosen to determine the severity of cold hypersensitivity. Result 1 male and 22 female patients were participated ranging in age from 22.17 to 45.21. There was a significant negative correlation between the recovery rate of finger skin temperature after cold stress test and the VAS score. And there was a significant positive correlation between the difference of finger skin temperature and the back and palm of hands after cold stress test and the VAS score. Conclusion In cold hypersensitivity patients, the cold stress test combined with DITI could be a accurate method for the objective evaluation of cold hypersensitivity, especially good at deciding the severity by numeric values. Using a more strict criterion, as diagnosing of cold hypersensitivity, and longer follow-up may improve the validity of the results attained in clinical trials.

한지영,김광수,서민석,황경균,박창주,Han, Ji-Young,Kim, Kwang-Soo,Seo, Min-Seock,Hwang, Kyung-Gyun,Park, Chang-Joo 대한치과마취과학회 2011 Journal of Dental Anesthesia and Pain Medicine Vol.11 No.1

Background: Since introduced by Gow-Gates GA in 1973, Gow-Gates mandibular nerve block (GMNB) has played an important role in the area of dental local anesthesia. However, compared to the conventional inferior alveolar nerve block (IANB), this technique seems to fail to attract the attentions of general practitioners in South Korea. The aim of this study was to prove the clinical real value, mainly the anesthetic efficacy, of GMNB in minor oral surgery. Methods: The study group comprised 40 patients (15 males and 25 females) who were randomly allocated to receive GMNB or IANB for extraction of third molars. Both techniques utilized two 1.8 ml dental cartridges of 2% lidocaine including 1:100,000 epinephrine for each patient. Pulpal and gingival tissue anesthesia of mandibular premolars and molars were recorded at 0, 15 and 40 minutes after administration of local anesthetics using both an electric pulp tester and a sharp dental explorer. Results: The success rates of pulpal and gingival tissue anesthesia in the IANB group were not significantly different from the GMNB group in overall efficacy. Patient's and operator's satisfaction ratings were also not significantly different between two groups. Interestingly, the injection pain of GMNB group was significantly lower than that of IANB group. Conclusion: This study demonstrated that the anesthetic efficacy of pulpal and gingival tissue of GMNB was not inferior to that of IANB. The GMNB could be a good alternative of the IANB in most of minor oral surgical procedures.

폐기물 관리법에 의하면 2001년부터 슬러지의 매립이 금지됨에 따라, 매립이외의 다른 처리방식을 도입해야 할 상황이다. 전과 정평가는 제품 및 서비스의 전과정을 통해서 발생하는 환경부하를 정량화 하는 방법으로 대두되고 있으며 환경성에 대한 정책의 입안 및 제품의 비교평가 등 그 활용분야가 다양하다. 본 논문에서는 전과정평가(Life Cycle Assessment, LCA)를 이용하여 슬러지의 처리방법 중 소각, 퇴비화, 고형화에 대한 환경성을 비교 평가하여 적절한 처리방식을 선정하는데 도움이 되고자 하였다. 각각 처리시설의 Data는 구리시 하수처리장의 소각시설, 난지도 하수처리장의 퇴비화 시설, 수도권매립지의 고형화 처리시설을 방문하여 운영자료를 사용하였으며, 국내 D/B로 구축된 전력 및 수송자료도 이용하였다. 전과정 평가를 수행한 결과 퇴비화가 가장 낮은 환경 부하를 나타냈고. 고형화 처리방식이 가장 큰 환경부하를 나타냈다. As it is not allowed to landfill sludge from 2001 by the act of waste management, new systems of treating sludge are necessary. Life Cycle Assessment, LCA, is a method for evaluating systems in the aspect of environment and also can apply to decision making tools for policy making. The objective of this study is to assess 3 alternatives of landfill: incineration, composting, solidification by applying LCA. This study is done with operation data from incinerator in Kuri, composting facility in Nanjido, solidification facility in Kimpo and electricity and transport data of Korea in 1998 are used. The results of the LCA is that the composting system is most environmental-friendly and the solidification system is least environmental-friendly.

간호대학생이 인지한 COVID-19 낙인 및 의료종사자에 대한 낙인이 COVID-19 스트레스에 미치는 영향

한지영(Han, Ji-young),이내영(Lee, Naeyoung),김명자(Kim, Myungja) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.5

목적 임상실습이 반드시 필요한 간호대학생이 COVID-19로 인해 경험하는 COVID-19 스트레스를 살펴보고 이에 영향을 미치는 COVID-19 낙인, 의료종사자에 대한 낙인을 확인하여, COVID-19 스트레스를 관리하기 위한 기초자료를 제공하고자 한다. 방법 본 연구는 서술적 조사연구로 B시 소재 간호학과 학생 300명을 편의추출하였다. 자료수집은 2021년 4월 1일부터 5월 15일까지 하였으며 COVID-19 대유행과 감염병의 특성상 구조화된 설문지를 사용하여 온라인 서베이하였다. 자료분석은 SPSS 24.0을 사용하여 빈도, 백분율, t-test, F-test, Pearson correlation, 다중회귀분석하였다. 결과 COVID-19 스트레스는 4점 만점에서 평점 1.0이며, 하부 영역에서는 ‘위험과 오염’이 1.3으로 가장 높았고 ‘외상성 스트레스’가 0.4로 가장 낮았다. COVID-19에 대한 낙인을 인지하는 경우가 30.8%이었다. 의료종사자에 대한 낙인은 4점 만점에서 평점 1.7이며, 세부 문항 중에는 ‘의료 종사자는 COVID-19에 걸리기 쉽다’가 2.6으로 가장 높았고 ‘모든 의료 종사자와 함께 있고 싶지 않다’가 0.8로 가장 낮았다. COVID-19 스트레스에 영향을 미치는 요인에서는 COVID-19 낙인은 COVID-19 스트레스에 영향을 미치지 않았으며(β=-0.1, t=-1.944, p=.053) 의료종사자에 대한 낙인이 1증가할 때마다 COVID-19 스트레스가 0.3 증가하였다(t=4.483, p<.001). COVID-19 상황에서 간호대학생은 위험과 오염, 외국인 혐오증에서 COVID-19 스트레스를 높게 인지한 반면 외상성 스트레스와 사회경제적 결과에서는 COVID-19 스트레스를 낮게 인지함을 확인하였다. 또한 COVID-19 스트레스는 COVID-19 낙인 보다는 의료종사자에 대한 낙인이 증가할수록 증가하였다. 결론 간호대학생의 COVID-19 스트레스를 감소시키기 위해서는 간호대학생의 감염관리 역량을 강화하며 일반인의 COVID-19 스트레스를 관리하여 의료종사자에 대한 낙인을 줄여야 한다. Objectives The purpose of this study is to identify the COVID stress(CS), Coronavirus stigma(CVS), and healthcare worker(HCW) stigmatization affected CS among nursing students. Methods Data collection began April 1, 2021 and ended on May 15, 2021. All participants completed the structured questions for creating online surveys due to the COVID-19 pandemic. For data analysis, frequency, percentage, t-test, F-test, Pearson correlation, and multiple regression analysis were performed using SPSS 24.0. Results During times of pandemic, nursing students significantly experienced more “danger and contamination” and “xenophobia” as factors of CS, but less “traumatic stress” and “socioeconomic consequences”. Also the influential factors on their CS were HCW sigma (β=.3, p<.001). Conclusions In order to reduce the CS of nursing students, it is necessary to strengthen their infection control competencies and reduce public’s HCW stigmna through their CS management.

방과후 교실 아동의 몰입에 관한 문화기술적 연구

한지영(Han Ji-Young) 질적연구학회 2006 질적연구 Vol.7 No.1

The purpose of this study is to understand the characters of children’s flow as autotelic experience. “Flow” is an experience that is at once demanding and rewarding, the suspension of time and the freedom of complete absorption in activity. In order to meet the purpose of the study, I analyzed the meanings and characters of children’s flow by qualitative data of ethnographic research. For the qualitative data collection, one of the elementary’s “After School Program” was chosen, I conducted participant observation and interviewed children about their life in general and flow experience in particular from August 1th, 2004 to November 5th, 2005. I carried out a series of in depth interviews with 9 children about their flow experiences. The children who flow by autotelic experience have common characters and features as follows: First, great inner clarity: knowing what needs to be done and how well it is going. Second, freedom: feeling when is doable under control by themselves. Third, creativity: doing one’s own style afterwards imitation of the existing form. Fourth, happiness and pleasure: pleasure is a feeling when focused on present thoroughly, don’t notice time passing and happiness is a feeling afterwards the completion of activity. Fifth, tolerance: cultivating when needs to be challenged and required great effort. The speculative subject takes the form of expressing their thoughts and emotions as they write, draw, sing, read and so on. The children’s flow of speculative subject mature intrinsically by empathy, sublimation of grief and reflection. The active subject is to be seen as an achievement of result as they cook, play soccer, make and so on. The children’s flow of active subject results in interchanging, sharing and acknowledging with others. The children who have been flow find their ego, experience society and realize creativity. As my studying results, the people will be support children’s flow as autotelic experience if they understand the children’s growth for flow.
