신민,안도희 한국교원교육학회 2016 한국교원교육연구 Vol.33 No.1

본 연구는 영재교사의 역량 강화를 위해 영재교사역량 척도(The GATE Scale)를 개발하여 이에 대한 신뢰도와 타당도를 검증하고자 하였다. 본 연구에서는 영재교사 연수를 이수한 전국의 영재담당 교사 210명을 대상으로 설문조사를 실시하였다. 이 중 불성실하게 응답한 22명을 제외한 나머지 총 188명(회수율 89.5%)을 최종 분석대상으로 선정하였다. 영재교사역량 척도는 ‘영재성에 대한 이해(Understanding Giftedness)’ 요인, ‘영재의 정의적 특성에 대한 이해(Affective Characteristics)’ 요인, ‘영재 수업 기술(Teaching skills)’ 요인, ‘영재교사의 전문성(Expertise in gifted education)’ 요인 총 4개 하위요인으로 구성되었다. 본 척도의 신뢰도와 타당도를 검증하기 위해 탐색적 요인분석과 확인적 요인분석을 실시하였으며, 이를 토대로 구성된 영재교사역량 척도의 수렴 타당도를 검증하였다. 그 결과, 첫째, 탐색적 요인분석을 통해 4개의 하위요인, 총 23개 문항으로 최종 선정되었으며, 요인별 신뢰도는 .748 ~ .892로 나타났다. 둘째, 확인적 요인분석을 통해 영재교사역량 척도는 ‘영재성에 대한 이해’ 요인(6개 문항), ‘영재의 정의적 특성에 대한 이해’ 요인(4개 문항), ‘영재 수업 기술’ 요인(6개 문항), ‘영재교사의 전문성’ 요인(7개 문항), 총 4개 하위요인(총 23개 문항)으로 최종 확인되었으며, 영재교사역량 척도의 전체 신뢰도는 .932로 나타났다. 셋째, 수렴 타당도 검증 결과, 영재교사역량 척도의 4개 하위요인(‘영재성에 대한 이해’ 요인, ‘영재의 정의적 특성’ 요인, ‘영재수업 기술’ 요인, ‘영재교사의 전문성’ 요인)은 모두 교사역량, 교사 효능감, 교수신념, 교사 직무환경과 유의미한 정적 상관을 보였으며, ‘영재수업 기술’ 요인과 ‘영재의 정의적 특성’ 요인은 교사 역할과도 유의한 정적 상관이 있는 것으로 나타났다. 이러한 본 연구 결과를 통해 타당도가 검증된 영재교사역량 척도는 향후 영재학생을 담당하는 교사 선발과 평가를 위한 진단 및 영재교사 연수를 위한 기초자료로 활용될 수 있을 것으로 기대된다. This study aimed to define the construct of the teacher competencies for the gifted and describe the development of the The GATE Scale. The GATE Scale delineates four factors that are ‘understanding giftedness’(6 items), ‘understanding affective characteristics of the gifted’(4 items), ‘teaching skills for the gifted’(6 items), and ‘expertise in gifted education’(7 items). The GATE scale was verified and refined through exploratory and confirmatory factor analyses. It was also found that the GATE scale was significantly correlated with teacher competency, teacher efficacy, teaching beliefs, and teaching job environment and teacher role. The results supported good reliability, and construct and convergent validities of the GATE scale.

This study was designed to investigate the effects of several soft drinks including sports drink on the erosion of the permanent teeth. 40 sound teet were obtained from extracted human premolars for orthodontic treatment. Specimens were divided into 4 groups and treated with soft drinks as follows; Group 1 : sports drink(pH 3.45) , Group 2: cola(pH 2.58), Group 3: cider(pH 2.93), Group 4: natural water(pH 7.1) All teeth were covered in acid-resistent wax except for 5 X 7㎜ window and exposed to the test solution for 2 hours. Microhardness, color differences and calcium ion concentration were measured before and after exposure. The obtained result were analyzed with Window SPSS 10.0 and as follows: 1. Microhardness were very significant decreased as exposure of cola and cider (P<0.001), and also decreased in group of sports drink significantly(P<0.05). 2. Colors were differed after exposure of soft drinks in only group of cider(P<0.01) 3. After exposure of cola and cider, there were significant increase of loss of calcium ion concentrations(P<0.001) and had a tendency of increase of loss of calcium ion in group of sports drink(P<0.05).

표면마취가 저작근 및 경부군의 압력통각역치에 끼치는 영향에 관한 연구

신민,Shin, Min 대한안면통증구강내과학회 1997 Journal of Oral Medicine and Pain Vol.22 No.1

Pressure pain thresholds are routinely used in orofacial pain research to evaluate the response of deep orofacial tissues to mechanical stimulation. Like other psychophysical measurements, however, this technique must stimulate cutaneous tissues before stimulating deeper tissues. This study aimed at evaluating the influence of the cutaneous hypoesthesia on the pressure pain threshold in 30 healthy volunteers. PPTs were determined with electric pressure algometry over masseter, temporalis anterior, sternocleidomastoid, and trapezius muscle before and after skin hypoesthesia. A local anesthetic cream and a control cream were applied following a placebo-controlled double-blind design and PPTs were reassessed. Two examiners measured PPTs two times on each muscles, randomly. And the EMG activity of all muscles were measured to evaluate the relationship with PPTs. The collected data were processed by SAS/STAT program. The obtained results were as follows : 1. There were a tendency to increase PPTs after than before cutaneous hypoesthesia, but, there were no significant difference statistically. 2. PPTs were consistently higher in anterior temporalis than in masseter muscle. 3. In all occasions, PPTs were higher in males than in females(p<0.001). 4. A statistically significant correlation was obtained from values of intra-examiners and inter-examiners in all measured muscles. 5. A significantly positive correlation was not found between PPT and functional EMG activity.

신민,김재창,Shin, Min,Kim, Jae-Chang 대한안면통증구강내과학회 1997 Journal of Oral Medicine and Pain Vol.22 No.2

This study aimed at evaluating tile relationship between pressure pain threshold(PPT) and electromyographic(EMG) activity in 30 healthy volunteers and 30 patients with temporomandibular disorders. PPTs were determined with electric pressure algometry over masseter, temporalis anterior, sternocleidomastoid, and trapezius muscle during resting and clenching. To obtain more reliable result, two examiners measured PPTs two times on each muscles, randomly. Resting and clenching EMG activity and tenderness of all muscles were measured to evaluate the relationship with PPTs. The collected data were processed by SAS/STAT program. The obtained results were as follows : 1. Pressure pain thresholds in tendered muscles were lower than those in non-tendered muscles. This tendency was more prominant in masticatory muscles than in cervical muscles and in clenching than in resting. 2. There ware a tendency of higher PPTs in unaffected side than in affected side, but there were no significant difference statistically. 3. There wert no difference of PPTs between in preferred side and in ipsilateral side, significantly. 4. There was a significantly positive correlation between resting and clenching PPTs, but there were no correlation between PPTs and EMG activities. 5. Comparison of EMG activity between in higher group and in lower group by resting PPTs didn't show any significant difference. But resting EMG activity in the higher group of clenching PPTs were lower, on the contrary, clenching activity were higher than those in lower groups of clenching PPTs. From this results, the author concluded that the clenching PPTs was more important than resting PPTs in diagnosis of muscle dysfunction. And the author recommanded that all of three following test were performed for the proper diagnosis and treatment of orofacial Pain : muscle tenderness, EMG activity, and PPT.

구강내 백색병소와 편평상피세포암종에서 bcl-2와 NOS₂ 비교발현에 관한 연구

신민,김은철,Shin, Min,Kim, Eun-Cheol 대한안면통증구강내과학회 1999 Journal of Oral Medicine and Pain Vol.24 No.2

The proto-oncogene bcl-2 confers a survival advantage to cells by blocking programmed cell death (apoptosis). Overexpression of bcl-2 probably plays a role in tumorigenesis, and the expression of the bcl-2 protein has been investigated in many kinds of tumors. An increased expression of nitric oxide synthetase(NOS) has been observed in human colon cancer cell lines as well as in human gynecological, breast, and CNS tumors. However there have been only a few reports on the expression of bcl-2 and $NOS_2$ in oral white lesions and cancer. The aim of this study was to investigate the relationship between the expression of Bcl-2 and $NOS_2$ and several pathological parameters such as histological types and layers. We reported desregulation of bcl-2 and $NOS_2$ expression during progression from oral white lesion, lichen planus and leukoplakia to squamous cell carcinoma. The obtained results were as follows: 1. Immunohistochemical analysis with monoclonal antibodies to bcl-2 oncoprotein and $NOS_2$ in formalin-fixed paraffin-embedded tissue sections revealed that bcl-2 expression is restricted to the basal cell layer and $NOS_2$ was mild expressed only in subepithelial inflammatory cells in normal human mucosa. There wasn't specific finding of those in lichen planus and leukoplakia. 2. Bcl-2 immunoreactivity in severe epithelial dysplasia or CIS occurs throughout the epithelium, $NOS_2$ reactivity in most superficial layer were noted. 3. In well-differentiated squamous cell carcinomas, mostly bcl-2 was overexpressed. In moderated and poor squamous cell carcinomas, the expression of $NOS_2$ was increased and that of bcl-2 was decreased. 4. The immunoreactivity of bcl-2 was 12.5% of normal mucosa, 30% of leukoplakia, 44% of lichen planus and 67% of carcinoma in situ. In carcinoma, those were 43%, 50% and 67% according to differentiation, respectively. 5. The immunoreactivity of $NOS_2$ was 25% of normal mucosa, 70% of leukoplakia, 78% of lichen planus and 100% of carcinoma in situ and epithelial dysplasia. In carcinoma, those were higher in moderated(100%) and poor(83%) squamous cell carcinomas than in well differentiated type(71%). 6. The expression of bcl-2 and $NOS_2$ by Western blot was increased highly in lichen planus and leukoplakia. Therefore, the expression of bcl-2 was increased in the white and precancerous lesions and that was decreased by differentiation of carcinoma. However, $NOS_2$ immunoreactivity in carcinoma in situ was lower than those in moderated and poor squamous cell. These findings suggest that the interaction of bcl-2 and $NOS_2$ may be roled importantly in growth and development of carcinoma.

신민,안도희 韓國英才學會 2015 영재교육연구 Vol.25 No.2

This study was to examine perceptions of information technology(IT) competencies among gifted and non-gifted students(i.e., information science high school students and technical high school students). Of the 370 high school students surveyed from 3 high schools(i.e., gifted academy, information science high school, and technical high school) in three metropolitan cities, Korea, 351 students completed and returned the questionnaires yielding a total response rate of 94.86%. High school students recognized the IT professional competence as being most important when recruiting IT employees. And they considered that practice-oriented education was the most importantly needed to improve their IT skills. In addition, the most important sub-factors of IT core competencies among gifted academy students and information science high school students were basic software skills. Also Technical high school students responded that the main network and security capabilities were the most importantly needed to do so. Finally, the most appropriate training courses for enhancing IT competencies were recognized differently among gifted and non-gifted students. Gifted academy students responded that the ‘algorithm’ was the mostly needed for enhancing IT competencies, whereas information science high school students responded that ‘data structures’ and ‘computer architecture’ were mostly needed to do. For technical high school students, they responded that a ‘programming language’ course was the most needed to do so. Results are discussed in relations to IT corporate and school settings. 본 연구에서는 영재와 평재 고등학생들이 IT 역량을 어떻게 인식하고 있는지에 대해 비교해 보고자 하였다. 이를 위해 영재학교 2개교와 IT 특성화 고등학교 1개교 그리고 공업고등학교 1개교, 총 370명을 대상으로 표집 하였으며, 이들을 대상으로 IT 기업 인재 채용 시에 중요하게 고려되는 요인, IT 역량 향상을 위해 필요한 교과목과 이를 위한 효과적인 교육방법, IT 핵심 역량에 대한 생각에 대해 응답하도록 하였다. 이 중 351명을 최종 분석 대상으로 선정하여 분석한 결과, 고등학생들은 IT 기업의 신규채용 시 중요한 요인이 IT 전문역량이라고 인식하고 있었으며, IT 역량을 향상시키기 위해서는 실무중심 교육과 실습위주의 교육 등 ‘실습 위주 교육’이 가장 필요하다고 응답하였다. 또한, IT 핵심역량 중에서 가장 중요하다고 생각하는 하위 요인으로 영재학교와 정보과학고등학교는 ‘소프트웨어 기본역량’이 가장 중요하다고 인식하고 있었고, 공업고등학교는 ‘네트워크 및 보안 기본역량’이 가장 중요하다고 지각한 것으로 나타났다. 마지막으로, IT 역량 함양을 위해 가장 필요한 교육과정으로는 학교 유형별로 다르게 인식하고 있었는데, 영재학교 학생들은 ‘알고리즘’이 가장 필요하다고 인식하였고, 정보과학고등학교 학생들은 ‘자료구조’ 및 ‘컴퓨터 구조’의 필요성을 가장 크게 인식하고 있었다. 공업고등학교 학생들의 경우에는 ‘프로그래밍 언어’가 가장 필요한 교과목이라고 응답하였다. 또한, IT 기업 채용 시 중요한 요인(IT 전문역량, 학력, 기초직업능력, IT공통역량), IT 핵심역량 함양 교육방법(학교교육), IT 핵심역량 중요도(소프트웨어 기본역량, 데이터베이스 기본역량, 네트워크 및 보안 기본 역량, 통합적인 역량), IT 역량 향상을 위한 교육방법(운영체제, 하드웨어)에서 영재학생이 평재학생보다 더 중요성이나 필요성을 높게 인식하는 경향이 있는 것으로 나타났다. IT 교육을 받고 있는 영재학생, 정보과학고등학생 및 공업고등학교 학생들이 인식하는 IT 핵심역량을 비교분석한 본 연구결과가 향후 IT 인력 양성을 위한 교육과정 및 교육방법을 개선하고 보완하는데 기초자료로 활용될 수 있기를 기대한다.

This study was purposed to investigate the effects of occlusal splints on the muscle strength and muscle endurance. The subjects were 42 general undergraduate students(14), weight lifting(14) and rowing players (14) were participated as experimental and control group. Measured items were back muscle strength, grasping power, sit-up, chinning etc. It was measured before application of occlusal splints, 6 weeks and 12 weeks after. The obtained results was analyzed by SPSS PC 11.0 statistical program. The results were as follows; 1. In general undergraduate group, there is significantly differed only on grasping power item between experimental and control groups. There were significant differences on back muscle strength, grasping power and chinning between before occlusal splint and 12 weeks after occlusal splint. 2. There were no differences between experimental and control groups in weight lifting players, but all scores of measured items were higher in 12 weeks after occlusal splint than before occlusal splint. 3. In rowing players, there were no significant difference between two groups, however, there were differed on back muscle strength, grasping power and chinning scores between 12 weeks after and before occlusal splint. Therefore, long term use of occlusal splint, at least for 12 weeks, were helpful for enhancement of muscle strength and endurance.

Er:YAG 레이저를 활용한 와동형성시 컴포짓 결합강도

신민,지영덕,류성호,조진형,Shin, Min,Ji, Young-Duk,Rhu, Sung-Ho,Cho, Jin-Hyoung 대한안면통증구강내과학회 2005 Journal of Oral Medicine and Pain Vol.30 No.2

This in vitro study evaluated the influence of a flowable composite resin on the tensile bond strength of resin to enamel and dentin treated with Er:YAG laser and diamond bur. 96 Buccal enamel and mid-coronal dentin were laser-irradiated using an Er:YAG laser and treated with diamond bur. Each groups(48) were divided two small groups depends on acid-etching procedure. Light-cure flowable resin(Metafil Flo) and self-cure resin(Clearfil FII New Bond) were used in this study. After surface etching with 37% phosphoric acid and the application of an adhesive system, specimens were prepared with a hybrid composite resin. After 24hours storage in distilled water at 37$^{\circ}C$, all samples were submitted to the tensile bond strength evaluation, using a universal testing machine(Z020, Zwick, Germany). The obtained results were as follows: 1. TBS of acid-etching group were higher than those of non-etching group in both enamel and dentin treated with Er:YAG laser and diamond bur. Laser 'conditioning' was clearly less effective than acid-etching. Moreover, acid etching lased enamel and dentin significantly improved the microTBS of M-Flo. 2. In enamel, TBS of laser-irradiated group were lower than those of bur-prepared group. However, in flowable resin subgroup, there were not differed those between two groups in dentin. 3. In laser-treated group, TBS of flowable composite resin were higher than those of self-curing resin in dentin, however, there was no difference in enamel. From this study, we can conclude that the self- and light-cure composite resin bonded significantly less effective to lased than to bur-cut enamel and dentin, and that acid-etch procedure remains mandatory even after laser ablation. We suggest that Er:YAG laser was useful for preparing dentin cavity with flowable resin filling.

도시홍수 방재시스템의 가치 추정 연구-광주광역시를 중심으로

신민 한국재난정보학회 2023 한국재난정보학회 학술대회 Vol.2023 No.11

본 논문에서는 다차원법과 CVM을 이용하여, 도시홍수 방재시스템의 가치를 추정하였다. 방재사업은 예산의 편성과 집행 과정 중에 연기 또는 집행 순서가 변경되기도 한다. 이는 즉각적인 효과가 드러나기 어려운 특징 등 때문에 시민 공감을 얻기에 어려우며, 정치적이고 경제적인 요인 등에 의한 것으로 추정된다. 따라서 시민들이 체감하고 있는 방재사업의 가치 규모를 추 정하고자 하였다. 정책 공급자들이 홍수 방재 사업의 추진 결정에 참고하는 가치와 시민들이 생각하는 가치를 다차원법과 CVM으로 각각 추정한 결과, 다차원법으로 산정된 가치보다 시민들의 필요 가치가 낮게 추정되었다. 따라서 정책 수요자들의 공감을 이끌어 내기 위한 노력을 지속해야 할 것이다.
