What Impact does Physical Education have on Classroom Management?: Focus on a case of a novice teacher in a primary school
This article aims to address the relationship between physical education and classroom managemen of a novice teacher in a primary school. In conclusion, the things of this case study were as follows: (1) As a feature of the novice teacher A, the scores in "Attitude" dimension of physical education class evaluation was high, then learning discipline was retained. However, the scores in "Human Relationship" dimension of class consciousness showed low value, and it turned out that the novice teacher A was suffering from constructing good human relations within the class. (2) From the result of correlation between physical education class evaluation and classroom manegement, there was no strong relationship between physical education and classroom management of the novice teacher A. As a factor, from the interview of the novice teacher A, it was suggested that the image of classroom manegement the novice teacher A intended was not clear
A Multicenter Phase II Study of Gemcitabine plus S-1 Chemotherapy for Advanced Biliary Tract Cancer
The utility of apoptosis inhibitor of macrophages as a possible diagnostic marker in patients with Crohn’s disease
Chemical constituents of Evolvulus nummularius
492-498Three new compounds, 1-3 together with known compounds, β-sitosterol and its glucoside, stigmasterol, d-mannitol, ursolic acid and oleanolic acid have been isolated from the aerial parts of Evolvulus nummularius. On the basis of their spectroscopic data and chemical study, the structures of the new compounds 1-3 have been established as 3-O-(4-stearoyl-Z-coumaroyl)-stigmast-5, E–22–dien-3β-ol; 16-(E-coumaroyloxy)-palmitic acid and 3β-hydroxy-urs-12-en-29β-oic acid, respectively. Possibly compound 3 is identical with plectranthoic acid, whose structure was wrongly assigned as 3α-hydroxy-urs-12-en-29β-oic acid
Phytochemical investigation of <i>Gomphrena globosa </i>aerial parts
2223-2227One new triterpenoid saponin (gomphrenoside,1)
and one new hopane derivative (hopan-7β-ol,2) along with known compounds,
β-sitosterol-β-D-glucoside
and 1-triacontanol have been isolated from the aerial parts of Gompizrena globosa.
On the basis of chemical and spectroscopic(including 20 NMR) methods, the structure
of 1 has been elucidated as 3β-O-α-L- arabinopyranosyl-6β-hydroxyolean-12-ene-23,29-dioic
acid-29-O-β-D-glucopyranoside and structure
of 2 is determined

Expeditious reaction of ninhydrin with active methylene compounds on montmorillonite K10 clay
International audienceNinhydrin reacted expeditiously with thirteen active methylene compounds on montmorillonite K10 clay at room temperature to furnish, in 5 min, a Knoevenagel condensate in one case, aldols in six cases, aldol-derived cyclic hemiketals in three cases, and interesting products in the remaining three cases. Almost identical results were obtained, but faster, when the reactions were carried out in water on steam-bath. The structures of two novel products were also confirmed by single-crystal X-ray diffraction analysis
Triterpenoids from <i>Bignonia unguis- cati</i> roots
1735-1739One new triterpenoid named
acetylbignonic acid 1 along with 2a-hydroxyursolic acid 2
have been isolated from the roots of Bignonia unguiscati. On the basis
of chemical and spectral evidence, the structure of 1 has been
established as 3b-acetoxy-19-hydroxyurs-12-en-29-oic acid
Chemical constituents of <i style="">Mussaenda incana</i>
2362-2366One new iridolactone, shanzhilactone 1 along with known iridoidglucosides,
mussaenoside, barlerin (8-O-acetylshanzhiside methyl ester), lupeol and β-D-glucose have
been isolated from the stem of Mussaenda
incana (Rubiaceae) and their structures elucidated by spectroscopic and
chemical studies
Steroid and nitro phenol esters from <i>Bignonia unguis-cati roots</i>
1514-1518Two new esters, β-sitosterol cerotate 1
and 2-(4-hydroxy-3-nitrophenyl)ethyl stearate 2 have
been isolated from the roots of Bignonia unguis-cati (Bignoniaceae) and
their structures are elucidated by spectroscopic and chemical studies
