The purpose of this study was to research what direction the Korean vocabulary education had to be steered by identifying the trends of research on Korean vocabulary education. Initially, I searched the RISS with the keyword “Korean vocabulary education” and organized the relevant data by year, learner characteristics, and vocabulary type etc. Through the data analysis, I was able to identify several trends. The trend by could be divided into three different time periods depending on the trend of study. Although research on learner proficiency was evenly represented, the studies on the nationality of target learners were mostly represented by Chinese while studies on the types of learners were mostly represented by married foreign immigrant women. Overall, Traditional Chinese (Hanja) contributed the largest proportion of research and I incorporated a variety of research methods such as teaching material analysis, experimental research and surveys in my research. As for the measures for teaching, research on teaching methods were the most popular. Through these results, I propose that more research needs to be done based on the geography of language, proficiency levels, special purposes, and various languages while the measures for teaching be objectively evaluated through this research.

오은화(Eun-Hwa OH),조양희(Yang-Hee JO) 한국상담심리교육복지학회 2021 상담심리교육복지 Vol.8 No.5

본 연구는 상담자가 수퍼비전에서 경험하는 자기성찰 경험과 그 경험의 본질을 이해하고자 수행하였다. 이를 위해 상담자 발달단계에서 중급 이상의 상담자 4명을 대상으로 반구조화된 인터뷰를 실시하고 Giorgi 현상학적 연구방법으로 자료를 분석하였다. 분석 결과, 수퍼비전에서의 성찰경험에 관해 의미단위 38개, 하위구성요소 12개, 상위구성요소 6개가 도출되었다. 상담자들은 수퍼비전에서 성찰과 관련되어 ‘수퍼비전 성찰의 촉진과 방해요인’, ‘수퍼비전에서의 정서경험’, ‘나를 돌아보는 과정’, ‘관계에 대한 깊은 이해’, ‘변화와 실천’, ‘전문가로서 성장함’을 경험하였다. 연구 참여자들이 상담자로서 성장하는데 성찰경험이 중요한 요인으로 작용하였고, 성찰은 인식과 실천이 동반되고 그 것이 순환과정을 거친다는 것을 알게 되었다. 본 연구에서는 상담자의 성장 요인인 자기성찰 과정을 상담자들이 어떻게 경험하는지와 그 경험의 본질을 이해하였다는데 의의가 있으며, 이를 바탕으로 연구의 제한점 및 후속 연구에 대해 제언하였다. This study was conducted to understand the introspection experience experienced by counselors in supervision and the essence of that experience. For this purpose, semi-structured interviews were conducted with 4 counselors at the intermediate level or higher in the counselor s development stage, and the data were analyzed using the Giorgi phenomenological research method. As a result of the analysis, 38 semantic units, 12 sub-components, and 6 components were derived for the reflective experience in supervision. Counselors related to reflection in supervision, facilitating and hindering supervision reflection , emotional experience in supervision , reviewing myself , deep understanding of relationships , change and practice , as an expert growth was experienced. It was found that the experience of reflection acted as an important factor in the study participants growth as counselors, and that reflection is accompanied by awareness and practice, and that it goes through a cycle. This study is meaningful in understanding how counselors experience the self-reflection process, which is a growth factor for counselors, and the essence of that experience. Based on this, limitations of the study and follow-up studies were suggested.

본 한국 보건산업은 병원들의 경쟁과 함께 급격히 변화하고 있다. 과거에 병원은 경쟁력있는 전략방법없이 이윤을 창출하였다. 게다가 병원은 고객들의 요구와 원하는 것을 중요하게 여기지 않았다. 그러나, 요즈음 점점 심해 지는 병원들의 경쟁은 경쟁적인 관리 전략과 고객관계관리를 매우 중요시 다루고 있다. 본 연구는 의료기관을 방문하 는 외래환자와 입원환자에 대해서 의료서비스를 받기 전의 기대만족도와 의료서비스를 받은 후의 만족도를 비교하고 VOC에 대한 환자들의 반응을 분석한 후 환자만족도를 높이기 위한 방안을 찾고자 한다. 연구의 방법은 환자의 만족 도를 좀 더 자세하게 파악하기 위해 본 연구의 목적에 맞게 개발된 설문지를 외래, 입원환자 각각 100명을 조사하였 으며 분석은 의료서비스의 전, 후의 만족도 비교이므로 Paired - Test와 기술통계등을 이용하였다. 연구결과 외래환자 는 간호사의 친절도에서만 만족도의차이가 통계적으로 유의한 것으로 나왔으나 입원환자의 경우 의료진과 직원의 친 절도 그리고 회진서비스에서 만족도의 차이가 통계적으로 유의한 것으로 나왔다. 따라서, 조사된 입원, 외래환자 만족 도 항목 중 의료서비스관련 만족도에 차이를 보이고 있으므로 그에 대한 좀 더 상세한 분석과 대책 방안 강구를 위 해 VOC 를 지속적으로 발전 활용하는 것이 환자만족도를 높이고 그에 따른 의료기관의 경영효율화를 높이는데 매우 도움이 클 것으로 사료된다. The Korean healthcare industry is rapidly changing along with the competition among hospitals. In the past, hospitals could make profit without designing competitive management strategies. Thus, they did not find importance in listening to customers' voices and identifying their wants. However, nowadays, the increasingly intense competition is encouraging hospitals to seriously consider competitive management strategies and Customer Relationship Management (CRM) activities to gain a competitive advantage and prosper. It tries to compare the expected satisfaction with the satisfaction of out-patient and in-patient and analysis of VOC(Voice of Customer). This survey was done from 27th, April, 2009 to 8th May and each 100 in-patients and out-patients. The paired t-test and descriptive analysis was used to analysis between before and after satisfaction. The result, the replied out-patients were the highest of I.M department, 43% and in-patients, surgery and other department are the highest each 22.0%. Nurses kindness is statistical significant in out-patients. Doctor, Nurse and staff’s kindness and rounding service was statistical significant in in-patients. Totally, the satisfaction was lower than expected satisfaction, so the medical care institutions should analyst detailed the patient’s satisfaction by VOC.

For the efficient energy use and the protection of environmental pollution, attrition characteristics, depending on the component and the condition of sorbent for the purification of fuel gas, were analyzed by a fluidized-bed tester. Results of these studies can be summarized follows. 1) When Mn-based sorbent(M, MT, MFT) prepared with varying addictives and induration conditions was compared in terms of particle size distribution and AI(Attrition Index), MT and MFT possessing TiO2 and Fe203 had much higher attrition resistance than M. Attrition resistance of M, MT and MFT increased as bentonite contents and induration temperature increased, when bentonite contents induration temperature were changed from 2 to 5% and from 1000 to 1100℃, respectively. Therefore when powdery catalysts are prepared, the attrition rate can be considerably affected by the controls of addictive, binder and induration temperature. 2) Attrition tests using MT1100-5 were performed under the conditions that particle size distribution was uniform and had much more over +270mesh and under -325mesh. AI due to attrition was 8.83, 21.54 and 1.67%, respectively. Thus, initial particle size distribution showed a great influence on both produced fines distribution and attrition loss. Therefore, the size distribution of particles injected initially and the particle size that carried over showed be considered to reduce the loss of particulate materials and the replacement cost due to attrition. 3) An experiment using MT1100-5 sorbent was also carried out to predict AI as a function of time and particle size distribution during 23hr. AI of prepared sorbent was 4.54, 7.73, 9.08, 11.35 and 12.48 after 1.5, 3, 5, 9 and 23hr. respectively. Thus, it was shown that the amount of produced fines during the same time was shorten with the increase of time. The operating condition of dust capturing equipment and the rate of powder exchange needs to be considered because most of the fines due to fluidization of particulate material was generated at initial operation.

본 연구는 상아질 혼성층의 교원섬유를 가수분해하는 효소인 MMPs (Matrix metalloproteinses) 억제제로 알려진 chlorhexidine (CHX)을 적용 후 결합강도를 측정하였으며, 이를 각각 열순환 처리 후 결합강도를 측정하였다. 또한 주사전자현미경으로 접착계면메서의 파괴 양상을 비교 분석하였다. 우식이 없는 발거한 32 개의 제 3 대구치의 교합면 상아질을 노출시키고 GI그룹에서는 dentin conditioner를 처리 후 2% chlorhexidine을 적용시키고, 산부식 접착제 그룹에서는 인산 산부식을 시행하고 2 % chlorhexidine을 적용 후 3단계 산부식형 상아질 접착제 (Scotchbond Multipurpose, SM), 2단계 산부식형 상아질 접착제 (Single Bond, SB)를 도포하고, 자가부식 접착제 그룹에서는 2 % chlorhexidine 적용 후 자가부식 상아질 접착제 (Clearfil Tri-S, TS)를 도포한다. 이후 복합 레진 (Z-250)과 GI (Fuji-II LC)를 충전한 시편을 1 ㎟의 단면을 갖는 beam으로 제작하여 열순환 하지 않거나, 10,000 회 열순환 (5 ~ 55 ℃)하였다. Universal testing machine (EZ-test: Shimadzu, Japan)에서 cross head speed 1 mm/min로 인장력을 가하여 , 미세인장결합강도를 측정하였다. 실험 결과는 유의수준 0.05 1evel에서 two-way ANOVA를 이용하여 통계분석하였다. 그 후 파절된 시편의 파괴 양상을 현미경 (SEM)으로 관찰하여 다음과 같은 갈론을 얻었다; 1. 2 % CHX을 적용한 모든 실험군에서 상아질과의 미세인장결합강도가 증가하였고, 열순환은 상아질과의 미세인장 결합강도를 감소시켰다 (P>0.05). 2. CHX 적용 후 열순환 한 군은 CHX을 적용하지 않고 열순환한 군에 비하여, 상아질과의 미세인장결합강도가 높았으며 , 특히 GI와 TS군에서 유의한 차이를 나타내었다 (P<0.05). 3. 파괴 양상 분석 결과, 혼성층에서의 접착성 파괴를 보이며, CHX을 적용하면 혼성층 기저부에서 상부로 파괴 부위가 옮겨가는 양상을 나타내었다. 이상의 연구 결과를 토대로, MMPs 억제제인 2 % CHX은 글래스 아이오노머 시멘트와 상아질 접착제의 초기 미세인장결합강도에는 영향을 미치지 않으며 ,CHX 적용이 접착 내구성을 유지하는데 도움이 되었다. The purpose of this study was to evaluate the effect of chlorhexidine (CHX) on microtensile bond strength (μTBS) of dentin bonding systems. Dentin collagenolytic and gelatinolytic activities can be suppressed by protease inhibitors. indicating that MMPs (Matrix metalloproteinases) inhibition could be beneficial in the preservation of hybrid layers. Chlorhexidine (CHX) is known as an inhibitor of MMPs activity in vitro. The experiment was proceeded as follows : At first, flat occlusal surfaces were prepared on mid-coronal dentin of extracted third molars. GI(Glass lonomer) group was treated with dentin conditioner, and then, applied with 2 % CHX. Both SM (Scotchbond Multipurpose) and SB (Single Bond) group were applied with CHX after acid-etched with 37% phosphoric acid. TS (Clearfil Tri-S) group was applied with CHX, and then, with adhesives. Hybrid composite Z-250 and resin-modified glass ionomer Fuji-II LC was built up on experimental dentin surfaces. Half of them were subjected to 10,000 thermocycle, while the others were tested immediately. With the resulting data, statistically two-way ANOVA was performed to assess the μTBS before and after thermocycling and the effect of CHX. All statistical tests were carried out at the 95 % level of confidence. The failure mode of the testing samples was observed under a scanning electron microscopy (SEM). Within limited results, the results of this study were as follows; 1. In all experimental groups applied with 2 % chlorhexidine, the microtensile bond strength increased, and thermocycling decreased the microtensile bond strength (P > 0.05). 2. Compared to the thermocycling groups without chlorhexidine, those with both thermocycling and chlorhexidine showed higher microtensile bond strength, and there was significant difference especially in GI and TS groups.
