신명섭,손영종,이영종 대한본초학회 2001 大韓本草學會誌 Vol.16 No.1

The effects of orally dosed Rehmanniae Radix on the propulsive peristalsis of rat was examined by measuring the transfer rates of barium-gum inside the rat's gastrointestine. The results were such as the followings : 1. Significant decrease of transfer rate was observed in the dried Rehmanniae Radix dosed group. 2. The decreasing rates of both the 3rd Rehmanniae Radix prep. and 9th Rehmanniae Radix prep. dosed group were higher than that of the dried Rehmanniae Radix dosed group. 3. The decreasing rat of the group of dried Rehmanniae Radix dosed together with Glycyrrhizae Radix and Amomi Semen was higher than that of the dried Rehmanniae Radix individually dosed group. 4. The decreasing rate of the group of atropine dosed together with dried Rehmanniae Radix was higher that of the dried Rehmanniae Radix individually dosed group. But, the decreasing rate of the group of adrenaline dosed together with dried Rehmanniae Radix didn't show much difference from that of the dried Rehmanniae Radix individually dosed group. These results suggests that Rehmanniae Radix has an inhibitory effect on the propulsive peristalsis of the rat's gastrointestine.

3-isoamyl-ethyl-amino-6-methyl-7-anilino fluoran(S-205)의 열 변색 현상에 관한 열역학적 연구

김명건,허영덕,김종규 단국대학교 1999 論文集 Vol.34 No.-

Absorption spetra of thermochromic of 3-isoamylethyl-amino-6-methyl-7-anilino fluoran(S-205) was investigated. The S-205 exists as a colorless lactone in aprotic solvents. However, the S-205 exists in the form of an equilibrium mixture of a colored zwitter-ion and a colorless lactone in protic solvents. In order to understand the interaction between the S-205 and the solvent, absorption spectra of the S-205 in various solvents were measured. The systematic increase of the λ_max of the S-205 correlate with the solvent polarity of the solvent in protic solvent and aprotic solvent. The enthalpy changes of the S-205 has also been investigated. From the variation of absorbance with temperature, the standard enthalpy changes △H_0 the equilibrium between the lactone and the zwitter-ion in various solvents have been determined. The standard enthalpy change △H_0 is approximately -7 kJ/㏖ in protic solvents. In acidic solution, the standard enthalpy change is measured to be to zero in protic solvents within the experimental error. When the carboxylic group is protonated in acidic solution, a poor interaction between the dye and the solvent is expected.

이명숙,이종갑 大韓小兒齒科學會 1985 大韓小兒齒科學會誌 Vol.12 No.1

This study was designed to find out the prevalence of dental anomalies. The clinical and roentgenographic examination was undertaken of 1,477 children at age from 2 to 13 years and statistic analysis was made. The results were as follows: 1. Among the examined patients, 308 patients showed dental anomalies. The prevalences of individual dental anomalies were as follows; congenitally missing teeth; 7.92%, supernumerary teeth; 7.58%, fused and geminated teeth; 3.39%, anomalies of crown shape; 2.57%, taurodontism; 1.76%, dens invaginatus: 0.34%, dilacerated teeth; 0.41%, malposed teeth; 0.41%, amelogenesis imperfecta and dentinogenesis imperfecta; 0.20%. 2. Between the groups with individual dental anomalies, what showed significant correlation were as follows; Between age and dens invaginatus was positive weak correlation, congenitally missing teeth and supernumerary teeth was negative weak correlation. And the correlation coefficiencies between male and female showed differences. 3. The sexual differences of the individual dental anomalies appeared in congenitally missing teeth, supernumerary teethh and taurodontism. While the congenitally missing teeth and taurodontism showed greater rate of prevalence in female, supernumerary teeth in male. 4. In congenitally missing teeth, the mandibular deciduous lateral incisor showed the highest rate of the prevalence in deciduous dentition, while mandibular lateral incisor in permanent dentition. 5. Most supernumerary teeth were mesiodens of median area in maxilla and showed no statistical difference between right and left side. Generally, the eruption pattern of that teeth was normal posiiton and unerupted state. 6. In the case with deciduous fused teeth, the prevalence of succeeding permanent congenitally missing teeth was 47.06%, while that of succeeding permanent fused teeth was 5.80%. And the highest rate of the prevalence appeared in fusion of mandibular right deciduous lateral incisor and canine. Also, in mandible and right side, appeared greater rate of prevalence.

Duty, Task, Step 분석울 통한 전기·컴퓨터 분야의 DACUM Chart 활용 방안

박성종,지명석,류지호 한국직업능력개발원 2003 직업능력개발연구 Vol.6 No.2

Recently the DACUM methodology is widely used in vocational education fields because Curricula in vocational education, especially in engineering technology education, do not adequately mirror the needs of the work fields. DACUM Chart which contains a graphic portrayal of the duties and tasks identified, plus the descriptive lists of general knowledge and skills, future trends and concerns, worker behaviors, tools, equipments, supplies and materials is also useful. Certainly the DACUM methodology is effective, quick and low cost, but do not reflect the educational situation of internal vocational education institute effectively. The purpose of this study is to modify DACUM Chart for various work based learning strategies aimed at providing hands-on experience for students and consequently apply to curricula development. We performed the duty, task and step analyses through the verifications by expert workers, technicians and engineers of the workplace on the electricity and computer fields. Through this study, the practical tasks which must be instructed on the vocational education institute are suggested and modules are developed through the step analyses. So, we can reflect both the educational situation of vocational education institute internally and workplace effectively. And also we can manage curricula emphasizing the smooth transition of students from school to work to accept the needs of strategies for work based learning.

박종익,조영래,홍진표,이민규,한오수,이명종 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

저자들은 환청과 망상을 주소로 정신과를 방문한 진행성 핵상 마비 환자를 진단하고 치료하였다. 진행성 핵상 마비는 보행 장해, 치매, 수직성 안구 운동의 장해가 특징적인 증상이며, 아직까지 특별한 치료법은 알려져 있지 않다. 정신과적 증상으로는 인지기능의 장해, 정동 및 행동의 변화, 수면 장해, 정신병적 증상 등이 있으며 정신분열병과 비슷한 증상을 보이는 경우는 극히 드물다고 한다. 본 증례에서는 파킨슨 증상과 정신병적 증상이 비슷한 시기에 발현된 진행성 핵상 마비의 예를 보고하면서 진단적 중요성을 강조하고자 한다. We have experienced a rare case of progressive supranuclear palsy with hallucination and delusion. The common manifestations of progressive supranuclear palsy are gait disturbance, mental change and sign of vertical ophthamoplegia but no efficacious therapy has been known. Neuropsychiatric symptom clusters include cognitive impairment, affective and behavioral changes, sleep disturbance, and psychotic symptoms. Though schizophrenia-like psychosis has been reported but this is certainly rare. Addressing a case of progressive supranuclear palsy, in whom parkisonian symptoms appeared with concurrent psychotic symptoms, we emphasize accurate diagnosis.

체육실제학습시간(ALT-PE)의 이론적 고찰

김영명,이종목,옥영철 東亞大學校 附設 스포츠科學硏究所 1997 스포츠科學硏究論文集 Vol.15 No.-

I've researched on the method of learning time; considering the concept of learning time. AT has the property of learning opportunity. TOT and ALT can't clarify cognitive processes although they contain it. We can get an efficiency in learning time by concentrating on cognitive efforts. So the extension of learning time should not only represent the extension of learning opportunity but also the efficiency of learning time. The extension of learning time can be accomplished by increasing the proportion of the learning time, that students participate voluntarily within allowed time, and reducing the managing time that is needed for learning. In conclusion ALT is the most condensed concept in respect of quality. However, the students can's accomplish the efficiency of learning unless they don't have ALT. So we have to extend ALT in direction of AT in physical education.

DANSYL, BANSYL 및 DABSYL Chlorides의 가용매분해 반응에서의 용매화거동

李鍾八,成大東,金明淑 東亞大學校 1994 東亞論叢 Vol.31 No.1

The bimolecular nucleophilic substitution reactions of DABSYL and BANSYL chlorides have investigated by kinetic method and discussed with solvent dynamics that has been proved by means of laser flash photolysis. The results are as follows, 1. The rate constants of nucleophilic substitution reaction of BANSYL chloride show higher than those of DABSYL chloride in MeOH-MeNO2 binary solvent mixtures. The reactions proceed through an orbital-controlled reaction mechanism. 2. The phenomena of rate maxima show at 70% (v/v) content of MeOH in the solvolyses of DABSYL chloride and BANSYL chloride. The rate maximum is caused by the sum of the hydrogen bond donor acidity(α) and the polarity-polarizability parameter of solvent(π') as shown in the specific solvent effect as a general isodielectric solvent systems. 3. The laser flash photolyses of DABSYL chloride and BANSYL chloride are observed the fluorescent emission spectra which are generated by exciting of the two molecules. 4. The recovery life times of BANSYL chloride and DABSYL chloride are detected similar and the values of τ1 and τ2 are shown as shortest. 5. Rearrangement of the substrates in the content of 60% (v/v) of MeOH is depending on the rotation of the substrates on the surface of solvents by analysis of the rearrangement time.
