This study was performed to examine the effects of various macromolecules in in vitro growth (IVG) media on the growth, maturation, and parthenogenesis (PA) of pig oocytes derived from small antral follicles (SAF). Immature oocytes were cultured for two days in IVG medium supplemented with 10% (v/v) fetal bovine serum (FBS), 10% (v/v) pig follicular fluid (PFF), 0.4% (w/v) bovine serum albumin (BSA), or 0.1% (w/v) polyvinyl alcohol (PVA) and then maintained for 44 h for maturation. After IVG, the mean diameters of the SAF treated with FBS, PVA, and no IVG-MAF ($113.0-114.8{\mu}m$) were significantly larger than that of no IVG-SAF ($111.8{\mu}m$). The proportion of metaphase II oocytes was higher in PFF (73.6%) than in BSA (43.5%) and PVA (53.7%) but similar to that in the FBS treatment (61.5%). FBS and PFF increased cumulus expansion significantly compared to PVA and BSA while the intraoocyte glutathione content was not influenced by the macromolecules. Blastocyst formation of PA oocytes treated with FBS (51.8%), PFF (50.4%), and PVA (45.2%) was significantly higher than that of the BSA-treated oocytes (20.6%). These results show that the PFF and FBS treatments during IVG improved the growth, maturation, and embryonic development of SAF.

이한나 ( Hanna Lee ) 한국통합교육과정학회 2015 통합교육과정연구 Vol.9 No.2

이 논문에서 연구자는 교육과정 지식을 생성하는 교사의 내러티브적 사고 과정 탐구를 위한 연구 방법과 그것을 기반으로 한 연구 절차를 구축하고자 하였다. 교사가 내러티브적 지식을 생성하는 것은 자신의 경험에 대해 내러티브적으로 사고할때 가능한 것이기에 교사가 자신의 경험에서 지식을 생성해내는 일은 내러티브 탐구에서 내러티브 탐구자가 하는 일과 비슷한 일이라는 점에서 내러티브 탐구를 연구 방법으로 선정하였다. 이에 Clandinin과 Connelly의 내러티브 탐구를 기반으로 교사가 하는 일이 내러티브 탐구자가 하는 일과 같은 일임을 전제하는 연구자의 관점에 맞게 연구자와 참여자의 역할을 설정하고, 연구 과정을 설계하였다. 마지막으로는 사례 연구를 수행하여 연구자가 탐구하고자 하는 바를 드러낼 수 있는지 확인해보고, 연구자가 구상한 연구 과정을 구체화하였다. 연구의 결과는 다음과 같다. 첫째, 연구 참여자에게 수집할 교육과정 이야기, 즉 연구 참여자가 구성할 현장 텍스트는 시간성, 사회성, 장소성이 드러나는 내러티브여야 한다. 둘째, 연구자는 참여자의 이야기를 다시 말하는(retelling) 역할을 해야 한다. 셋째, 사례 연 구를 통해 읽어낸 이교사의 내러티브적 사고 과정(의식화 → 시각화 → 형식화/생성)은 본 연구에서 연구 참여자들의 사고 과정 탐구를 안내할 수 있을 것이다. This study aims to develope a procedure for research to explore the narrative thinking process of teachers creating a curriculum knowledge. Teachers can create narrative knowledge thought narrative thinking about their experiences. So I selected narrative inquiry as a research method in terms of teachers and narrative inquirer perform similar role. And I reset the role of researchers and participants, and developed a research procedure in terms of my standpoint based on Clandinin and Connelly’s narrative inquiry. Finally, I conducted a pilot study to see if this process can reveal what I want to explore, and to refine the research procedure. As a result of the pilot study, I ensured that the research procedure can work and found the following implications for the study. First, the curriculum story which I gather, that is, the field text which participants make, is narratives that are reveal temporality, sociality, and place. Second, the researcher perform retelling serves the story of the participants. Third, Lee’s narrative thinking processes (Mental planning→Visualization→ Formalization/Generation) that I found through a pilot study will be able to take advantage of the framework of the next inquiry.

This case report introduces a 74-year-old male patient who visited retention deficiency of the mandibular implant overdenture, which was fabricated 20 years ago. When the existing dentures were used, the vertical dimension was reduced, the maxillary complete denture lacked lip support and retention, and the mandibular overdenture lacked clip retention due to damage to the bar attachment. After removing the damaged bar attachment, it was replaced with a ball attachment, and impressions were taken using the DENTCA^TM Tray and then the vertical dimension was measured. The gothic arch tracing was performed to record the centric relation. Obtained impressions were scanned and the shape of final dentures was designed using software and try-in dentures were fabricated using 3D printer. After evaluating the occlusal plane, occlusal relationship, facial shape, and pronunciation using the try-in dentures, the bite registration was recorded, and the final denture was manufactured based on this. The inner surface of the denture was adjusted and bilateral balanced occlusion was formed, and the housing was connected to the mandibular denture by a direct method. This case reports have shown satisfactory resultin recovering improved retention and esthetic outcome by increasing the vertical dimension and the lip support using CAD-CAM technique and the ball attachment.

이한나,Lee, Han Na 대한심미치과학회 2014 Journal of the Korean Academy of Esthetic Dentistr Vol.23 No.2

가지런한 치열을 얻기 위해 교정 치료는 치아 보존적인 의미에서 단연 First choice가 일 수 밖에 없다. 그러나 왜소치나 치아 크기의 불균형인 경우, 변색 치아나 파절, 심한 마모 치아인 경우 교정만으로는 심미적으로 완성도 높은 결과를 가져올 수 없다. 모든 치료에서 그러하지만, 특히 심미 치료에서는 치아 교정과 보철 치료, 혹은 치주 치료 및 임플란트등 항상 통합적인 진단과 치료계획이 필요한 경우가 많다. 그리고 다양한 치과 분야의 협진 진료가 필요한 환자에서는 안모와 치아의 심미적 만족뿐 아니라 기능적인 교합관계를 이룸으로써 장기간 안정적이며 조화로운 상태가 유지될 수 있는 치료가 전제되어야 한다. 본 증례는 전치부와 소구치에 cross bite가 있고, 상악 우중절치 절단에 마모가 있는 37세 여성 환자에서 교정과 라미네이트 수복치료를 동반한 경우이다. 치아교정을 통하여 전체적인 치아 위치를 재구성하여 기능교합을 이루었고, 최소한의 치질삭제로 라미네이트 수복치료를 함으로써 전치부 심미를 회복하였다. 최종 보철물을 장착하고 2년간 주기적인 follow up통해 예후를 관찰중이며, 부정교합의 재발이나 보철물 파절은 현재까지 관찰되지 않았다. Orthodontic treatment is obviously the first choice to get aligned teeth cause of conservative treatment. But it is impossible to get highly esthetic result only orthodontic treatment in case of peg lateralis, discrepancy tooth size, discolored teeth or fractured teeth. As all treatment does, especially in esthetic treatment it is always required interdisciplinary diagnosis and treatment plan; orthodontics, periodontology, prothetics, implant therapy. As also, the treatment should be maintained long-term treatment with stable and harmonious state by esthetic satisfaction and functional occlusion those who needs various dental care as interdisciplinary treatment. This case is the laminate treatment with the orthodontic treatment on 37 ages/ Female patient who has cross bite at anteriors and premolar area and abrasion on centralis at right maxilla. By orthodontic treatment aligned teeth positions, it makes functional occlusion. As laminate treatment with minimum teeth preparation is able to release anterior esthetics. Follow up check for 2 years has been performed since the final prosthetics delivery to the patient. No sign of relapse, fracture of laminate were detected.

MBTI 성격유형에 따른 직무만족과 조직몰입에 관한 연구

이한나,신동주,Lee, Han-Na,Shin, Dong-Ju 한국산학경영학회 2010 산학경영연구 Vol.23 No.2

While machines can replace general industries, it is impossible to do so in service industries in which require various contacts with clients. As automated system would not work in service industries, it requires more of reliance to human resources than other industries. The services done here for customers are consequently reflected to the level of customers' satisfaction and business performance. Thus, highly qualified services are important factors for the success in the industry, but the problem here is that there is not enough care for employees providing those services. Therefore, this study analyzes employees' personalities and shows how those affect to job satisfaction and organizational commitment. It also aims at showing present problems in companies. MBTI, a test showing one's character, has been applied for the analysis, and surveys have been provided to employees to see how their personalities affect to job satisfaction and organizational commitment. Through this process, job satisfaction in accordance with one's character and organizational commitment is partially similar, and the hypothesis assuming that there is interrelationship between job satisfaction and organizational commitment was proved. 일반 산업은 기계로 대체할 수 있는 부분이 있지만, 서비스 산업은 다양한 고객을 응대함에 있어서 자동화되기는 곤란한 부분이 많다. 이로 인해 서비스 산업이 다른 산업에 비해 높은 인적의존도를 필요로 하게 되고, 여기에서 이뤄지는 대고객서비스는 바로 고객 만족과 경영성과에 반영되기 때문에 질 높은 서비스를 제공하는 것이 중요시 되고 있으나 그 이면에 그 서비스를 제공하는 직원에 대한 관심은 부족한 것이 현실이다. 따라서 본 연구는 직원들의 성격과 그 성격이 조직 내의 직무만족과 몰입에 어떻게 영향을 미치는지 파악하고, 기업의 현재 문제를 되돌아보고자 하였다. 이를 위해 MBTI 성격유형 검사를 통해 직원들의 성격유형을 알아보고, 이 성격유형이 직무만족과 조직몰입에 어떠한 영향을 미치는가에 대해 연구하였다. 이를 통해 성격유형에 따른 직무만족과 조직몰입은 부분적으로 유의함이 나타났고, 직무만족과 조직몰입 상관성의 가설이 검정 되었다.

Using market-selling rice flour, four rice wet noodles were prepared with three hydrocolloids: wheat flour, hydroxypropyl methyl cellulose (HPMC), and potato starch at different levels based on pre-test, and the physical and sensory properties of the noodles were measured and compared. The rice noodle with hydrocolloids showed much higher peak and final viscosity than wheat flour noodle (control). Rice noodle also showed higher hardness, cohesiveness and springiness than control in textural properties, however, the noodle with the highest hydrocolloids (wheat flour 15%, HPMC 12.5%, potato starch 17,5%) showed lowest cohesiveness and springiness values among samples. By sensory evaluation, the rice noodle with 15% wheat flour, 8.5% HPMC, 17.5% potato starch showed the highest scores in appearance, taste, texture and acceptability. HPMC in noodles seemed to influence on the noodle quality than potato starch or wheat flour. For making rice noodle, adequate level of hydrocolloids could improve noodle quality such as viscoelasticity, however, excess addition made the noodle coarse.

The purpose of this study was to evaluate nurses` perception of clinical nutrition services. A cross-sectional survey design was performed. The research was accomplished by using questionnaires developed for this study and administered from September 12 to December 31, 2013 to 343 nurses at 43 tertiary hospitals and 20general hospitals. The percentage of nurses who recognized clinical nutrition certificate as issued from nation was 27.8%. The mean scores of perceived usefulness on clinical nutrition services was 4.23/5.00, whereas that of perceived implementation was 3.76/5.00. The mean scores of necessity of disease-specialized clinical dietitian at capital hospitals were significantly higher for obesity (P<0.01), cancer (P<0.05), and infant & childhood disease (P<0.01) than at local hospitals. The rates of nurses` experience in group education on cancerat capital hospitals (21.7%) was significantly higher than that at local hospitals (10.3%) (P<0.05). The means cores of perceived importance of clinical nutrition services were 4.46/5.00 for ‘group nutrition education’, 4.46/5.00 for ‘individual consultation’, and 4.40/5.00 for ‘nutrition management for enteral nutrition (EN) patients’. The most common reason why clinical nutrition services are important was ‘improving mal nutritional status’. To activate clinical nutrition services especially at local hospitals, clinical dietitians should give systematic assistance to patients and also institutional supports are needed.

NCS 기반 사인디자인 교과목 운영-2년제 전문대학의 환경디자인 전공교육을 중심으로-

이한나 ( Hanna Lee ) 한국공간디자인학회 2016 한국공간디자인학회논문집 Vol.11 No.5

(배경 및 목적)정부는 산업체에서 요구하는 인재와 교육현장에서 배출되는 인재의 직무능력 간에 괴리를 없애고, 일과 교육, 훈련, 자격을 연계하기 위해 NCS(National Competency Standards)제도를 도입하여 추진하고 있다. 이에 부응하여 전문대학들은 정부가 제시하고 있는 표준체계를 토대로 산업체와 공동으로 교육과정을 개발하여 운영하고 있다. NCS 수업 운영 후에는 운영하는 주체의 실정에 맞도록 최초 개발된 교육과정을 보완하고, 그 내용을 반영하여야 내실있는 인재가 양성될 것이다. 본 연구의 목적은 최초 개발된 교육과정을 운영 후 발생된 문제점을 파악하고자 하였고, 무리하거나 미흡한 교육이 이루어지지 않도록 교육내용을 수정·보완하고자 한다. 연구의 범위는 서울소재 2년제 I대학교의 환경디자인전공 학과에서 운영한 NCS 기반 사인디자인 관련 교과목에 대한 분석이다. (연구범위 및 방법)운영시기는 2016학년도 2학년 1학기에 운영되었으며, 1회의 진단평가, 2회의 직무능력평가, 1회의 향상교육이 실시되었다. 수강인원은 2개 반 52명이었으며 평가는 2개 반 통합으로 진행되었다. 연구의 방법은 각 평가별 결과를 통계를 내어 분석하였다. 성취수준에 있어서 우수등급을 중심으로 진단평가와 수행평가의 발전정도와 각 수행평가별 성취도를 비교하였다. (결과)NCS를 기반 도시환경사인1 교과목의 수업을 운영한 결과는 다음과 같다. 진단평가에서 우수등급에 답한 학습자들의 비율에 비해 직무능력평가시 우수등급에 도달한 학습자들의 비율이 증가하였다. 디자인리서치, 아이디어 스케치 수행평가와 비교하여 컴퓨터그래픽 과제, 공간과 사인에 대한 관계를 이해하고 수행하는 과제물의 경우 성취도가 하락하였다. (결론)위의 결과에 따른 결론은 다음과 같다. 첫째, 기초적인 컴퓨터그래픽 활용실력을 갖출 수 있도록 도시환경사인1 수업을 수강하는 직전 학기에 선수과목을 개설해야 한다. 둘째, 공간과 사인의 관계에 대한 이해를 도울 수 있도록 학습모듈을 수정해야 한다. 셋째, 수업운영에 무리가 가지 않도록 능력단위와 능력단위요소의 개수를 축소해야 한다. 넷째, 진단평가 문항의 질문내용과 능력단위요소가 일치될 수 있도록 수정되어야 한다. 또한 상호연관성에 있어서 진단평가와 수행평가, 수행평가와 수행평가간의 관계가 균형있게 계획되어야 할 것이다. 본 연구는 환경디자인 분야라는 특정분야, 특정학과를 대상으로 진행된 것으로 디자인 교육 전반에 걸쳐 광범위하게 적용되기 보다는 특정학과에 한해서 적용될 것이다. 그럼에도 불구하고 본 연구가 가지는 가치는, 실제 운영된 자료를 기초로, 직업교육을 목적으로 하는 사인디자인 교육시 참고자료로 활용될 수 있을 것이다. (Background and Purpose)The Korean government has been promoting the imported National Competency Standards (NCS) system to not only narrow the gap between the students`` job skills and industry needs, but also link jobs, education, training, and qualifications. In response, colleges are developing and operating curricula in collaboration with the industry based on these standards. After implementing the NCS curriculum, the department should supplement the initial curriculum to match the circumstances to the operating department, and then nurture developmentally proficient students. This study identifies the problems that emerge from the initial implementation of these developing curricula, and suggests modifications to the curricula to rectify these problems and supplement the educational content to avoid insufficient instruction. (Scope and Method)This study focused on a particular case study regarding the implementation of NCS instruction in sign design in an undergraduate environmental design major at a two-year college in Seoul. The study was conducted during the spring 2016 semester on second-year students. The data collection and analysis consisted of one pre-diagnostic and two job ability evaluations. The class included 52 students who were divided into two classes (A and B); they were analyzed together to measure the degree of improvement from the pre-diagnostic evaluation across each performance evaluation component in the overall job evaluation. (Results)The results were assessed after instruction was given in Urban Environmental Sign Design I, which incorporated NCS standards. The percentage of students who reached a superior job ability level increased by the end of the study, compared to those in the pre-diagnostic evaluations. However, compared to the design research and idea sketch evaluations, the degree of achievements decreased in the case of assignments using computer graphics and involving an understanding of the relationship between space and signs. (Conclusions)First, the department should offer a basic computer graphics skills class as a prerequisite for Urban Environmental Sign Design I. Therefore, any student who takes this basic class during the previous semester can join Urban Environmental Sign I in the current semester. Second, learning modules should be modified to help students understand the relationship between space and signs. Third, the number of competency units and element units should be decreased to optimize learning. Fourth, pre-diagnostic questions should be modified to make them consistent with the contents of competency unit elements; additionally, instructors planning their lectures should balance the relationships between pre-diagnostic questions and each performance evaluation. This study targeted a specific field, which may not be applicable throughout design education, or to other fields; nevertheless, the study can be utilized as a reference for the development of learning materials and lesson plans for occupational education in environmental design.
