Consideration of Glenohumeral joint's image with the Changed Body angle of the Glenohumeral joint's Oblique Position in Erect Position. Glenohumeral joint's of Grashey method is a shoulder oblique method available to view the shoulder joint. Grashey method projects AP view of the Glenohumeral joint's so that the Humerus head's subluxation or joint degeneration can be easily visualized. However in this view, the patients, erect position, have to keep their body obliquely. Oblique position is will be needed to get the good quality Glenohumeral joint's view. Therefore, we thought of examining a method which shows the Glenohumeral joint's well by angling the patient one side upward in erect position. For this study, total 20 subject with no history of neurological or psychiatric illness, were recruited for examinations. They consisted of 13 mails and 7 femails, Statistic group analysis was performed with ANOVA test. Score of the evaluation of the expects were $30^{\circ}$ at $0.40{\pm}0.499$, $35^{\circ}$ at $1.34{\pm}0.657$, $40^{\circ}$ at $1.84{\pm}0.573$, $45^{\circ}$ at $0.76{\pm}0.649$, and they were significant(P<0.05). The degree of $40^{\circ}$ views were shown to yield good quality shoulder oblique images.

This work is to review the granite landforms studies by Korean geographers. It is verified that geomorphlogical characteristics of granite present landscapes characterized by 1) in case of mountains, are difficultly or irregularly weathered, so as to develop rocky forms such as domes, cliffs, and tors ; 2) in case of stream valley that is inter-massif lowland, low relief hills and flood plains with alluvium. All these facts owe to the difference of weathering mode granite properties. The granite hills and alluvial plains of southwestern coastal parts in Korean peninsula is low undulatory and large owing not only to the existence of highly weathered granitic regolith, but also to frequent flooding. Cultivated brownish field, orchard, meadow and forest are located at granite hills. On the other hand paddy rice field at granite alluvial plains. Korean peninsula have endured erodible geomorphlogical processes since Miocene when warping it up. Therefore many intermontane basins are located on the weathered granite areas which are surrounded by mountains composed of much less Precambrian gneiss complex. In fact, intermontane basin is mainly linear fault-line valley. The landforms of the intermontane basins are characterized by gentle piedmont slopes, alluvial fans, fluvial terraces and alluvial plains.
