In rock mass, great many discontinuity exists that is caused to various factors of formation. But these are parted to some groups by specific category, so called these as discontinuity set. This discontinuity set has unique special characteristics in original rock mass, but for the moment, differ the special quality if external force such as digging etc.. acts, specially, change of stress condition. Also, geometrical relation change between discontinuity orientation and direction of excavation various characteristic is seen. Therefore, we introduce here the useful chart that can do specification these relation.

The nail has been considered to be the best human model to evaluate the general body state at all ages. The present study was disigned to measure the nail growth rate and to define the correlation of them with other values of nail size. The subjects were 373 males and 812 females whose ages from R months to 79 years. The results were as follows: 1. The linear elongation of the nails were most rapid in the 14 to 15 year-old age group. It decreased steadily as the subjects got older and olr1er. 2. Sex differences in the nail growth rate were not statistically significant. R. Where were no statistically significant differences in the linear growth rate of nails between right and left hands. 4. The middle finger nail grew more quickly than others, while the thumb and little finger nails grew more slowly. 5. Linear growth of nails were not significantly correlated to the thickness and length of nails and the length of lunulae.

The pilomatricoma (Calcifying Epithelioma of Malherbe) is rare benign tumor of adnexal keratinocytes. It is occuring usually as a single, asymptomatic, 0. 5 cm to 3. 0 cm sized, deep seated, firm nodule, covered by normal or pink skin. Multiple pilomatricoma is relatively rare, as 3. 5% of reported cases of pilomatricoma. A 21-year-old male patient had 7 subcutaneous nodules on the neck, both upper extremities and trunk for 9 years. We excised one of them, under the impression of calcinosis cutis, cysticercosis cutis or benign skin tumor. But histopathologic findings of the lesion showed the typical pattern of pilomatricoma with shadow cells, calcification and foreign body giant cells. Five of remainders were excised and they showed same histopathological findings of pilomatricoma. The authors presented herein one case of multiple pilomatricoma with the review of literature.

Usually, cut-slope is the term that call rock slope. Therefore, the cause of instability of cut-slope is influenced generally in lithological and structure geological qualities including weathering disintegration. Through the several case studies, we could confirm that stabilization countermeasure also should be based in geological properties.

Backgroud: Female diffuse hair loss is a common baldness with a multifactorial origin. In recent studies, it has been suggested that reduced or depleted iron stores are a cause of female diffuse hair loss. Objeetive : We performed this study in order to elucidate the pathogenesis of female diffuse hair loss and to evaluate the differences in serurn iron levels between normal females and those with diffuse hair loss in Korea. Methods : Blood levels of hemoglobin, iron, TIBC, ferritin, testosterone, thyroid function, ANA and Zn were examined in 30 patients with female diffuse hair loss and 20 normal females. Results : 1) Serum Zn, testosterone, T4, TSH of the patient group were not statistically significant compared to those of the control group (p>0.05). 2) TIBC values were significantly increased, but serum ferritin levels were signifieantly decreased in the patient group (p<0.05). There were no significant differences in hemoglobin, serum iron in both groups (p>0.05). 3) No significant differences between clinical severity and the values of serum Zn, testosterone, T4, TSH, TIBC, serum femtin, hemoglobin and serum iron were observed (p>0.05). Conclusion : These findings suggested that the variations of TIBC, serum femtin levels may play a role in the pathogenesis of female diffuse hair loss, but further studies will be needed for evaluation of this condition.

Background: Alopecia areata, especially when severe, often profoundly affect the lives of those afflicted. Unfortunately, the clinical features and therapeutic results of alopecia areata are variable and unpredictable. Objective : The authors performed a study on alopecia areata in order to evaluate the clinical manifestations and the effects of treatment with intralesional injections of triamcinolone acetonide suspension, immunotherapy with diphenylcyclopropenone(DPCP) and combination therapy of intralesional injections of triamcinolone acetonide suspension and immunotherapy with DPCP. Methods : A clinical study of 357 patients with alopecia areata was performed fram March l994 to February l996 at the Department of Dermatology, Yongsan Hospital, College of Medicine, Chung- Ang University. Results : 1) The age distribution showed a peak incidence in the third decade(36.1%) and the average age was 27.6 years. 2) The most common site of predilection was the occipiital region in both male and female, which were 127 cases(73.0/o), 89 cases(64.5%) respectively. 3) The relapse rate was 26.1%. 4) The farnily histories were significant in 37 cases(10.4%). 5) Associated diseases with alopecia areata were seborrheic dermatitis, atopic dermatitis, hepatitis, diabetes mellitus, urticaria, allergic dermatitis, etc in 117 cases(32.8%). 6) The therapeutic effect in cases of bald areas treated with intralesional injections of triamcinolone acetonide, immunotherapy with DPCP and combination therapy revealed no difference based on increases in the size and number of bald areas. Conclusion '. These findings suggest that alopecia areata prominently develops in the third decade, when the severity of alopecia areata increases and the therapeutic effect decrenses. There was no difference in the therapeutic effect on the size & number of balded areas. (Korean J Dermatol 1998;36(5): 877-886)

N/A The εN-(?-L-glutamyl)-L-lysine cross-links in cornified envelope of the stratum corneum are formed by specific enzymes termed transglutaminase(TG). TG are calcium dependent enzymes that catalyse an acyl transfer reaction. Among them transglutaminase E(TGE) type is distributed in the granular layer and is also known as termiral differentiation marker of keratinocyte. This study was done to observe the distrubution pattern of TGE in the epidermis of various skin diseases by immunohistochemical PAP method using antihuman TGE antibody. Results were as follows : 1. Staining reaction for the TGE is strongest in the granular layer of the normal epidermis-TGE positive keratinocytes numbers are increased in the thickened granular and upper stratum spinosum in the dermatoses accompanying acanthosis with orthohyperkeratosis wherease decreased of absent in the dermatoses accompanying ?canthosis with parakeratosis. Atrophic epidermis shows decreased TGE staining reaction. 2. Staining reaction for the TGE is negative or weakly positive in dysplastic or atypical keratinocytes. Nonkeratinizing squamous cell carcinoma cells are negatively stained whereas keratinizing cells are positively stained according to the degree of keratinizing. Basal cells, whether in benign or malignant conditions were very weakly or negatively stained. Therefore, immunohistochemical staining for the TGE reveals the most abundant distribution in the granular layer and upper spinous layer in normal conditions and shows variation in its distribution with processes related to acanthosis, cornification and its terminal differentiation of keratinocytes.
