We have reviewed the 503 cases of benign skin tumors which were confirmed by histopathological study from January 1977 to July 1987 in the Dermatologic Department of Kyungpook National University Hospital. The result were summarized as follows . l. Among the total of 26,690 dermatologic out patients, 503 cases(1.9%) were diagnosed as having benign skin tumors. The number of benign skin tumors has shown a noticeable increase in the last several years. 2. The tumors were found mainly in ages ranging from the 2nd to 5th decade, most commonly in the 3rd decade(124 cases, 24.7%). 3. Aceording to Lever's elasaification, the tumors were divided into the following 7 groupa . tumors and cyets of the epidermis(35.2%), melanocytic tumors(16.5%), tumors of vaecular tissues(13.3%), tumora of epidermal appendages(11.1%), tumors of fibrous tissue(8.9%), tumors of neura.l tiasue(7.6%) and tumors of fatty, muscular and osseous tiseue(7.4%) in decreasing orders. 4. The 14 common tumors in order of frequency were as follows epidermal cyst (17.l% ),:rnelanocytic nevus(16.5%), neurofibroma(7.6%), congenital hemangioma(6.4%), nevus sebaceous(6.0%), lipoma(5.2%),seborrheic keratosis(4,8%), linear epidermal nevus(4.6%), steatocystoma mutiplex(2.8%), dermatofibroma(2.6%), hypertrophic scar and keloid.(2.6%), granuloma pyogenicum(2.4% ), keratoacanthoma(2.0%) and syringoma (2,0%). 5. The predilection sites of seborrheic keratosis, keratoacanthoma, syringoma and melanocytic nevus were the face, linear epiderrnal nevus, dermatofibroma and granuloma pyogenicum were located on the extremities. 6. The duration of tumors from the presumed time of onset to the first visit was within 1 year for epidermal cyst, keratoacanthoma and granuloma pyogenicum, over 10 years for nevus sebaceous, congenital emangioma and neurofibroma. 7. Diagnostic accuracy was higher in melanocytic nevus, congential hemangioma, nevus sebaceous and neurofibroma and lower in steatocystoma multiplex, dermatofibroma, keratoacanthoma, lipoma and epidermal cyst.

본 연구는 쌀의 다양한 용도개발을 위하여 당질미 계통들의 작물학적 및 이화학적 특성을 조사한 그 결과는 다음과 같다. 1. 당질미 계통들의 간장은 평균 90 cm로 남평벼에 비하여 6 cm정도 컸으며 현미 천립중은 $10.2{\sim}22.2g$으로 남평벼보다 가벼웠다. 또한 현미 평균 수량은 $159{\sim}473kg/10a$로서 큰 변이를 보였다. 2. 당질미들의 아밀로스를 제외한 일반성분 및 무기성분의 함량은 대부분의 경우 남평벼보다 많았으며 당함량은 남평벼에 비하여 최저 2.4에서 최고 6.1배 가량의 높은 당함량을 보였다. 특히 다른 당에 비하여 sucrose 함량이 높았다. 3. 아밀로펙틴사슬분포에서 당질미 계통들은 $DP{\leq}12$의 비율이 높고 $12<DP{\leq}24$의 비율이 낮은 것으로 나타나 phytoglycogen 합성이 많아진 것으로 사료되며 또한 호화특성은 대부분의 당질미 계통들은 매우 낮은 점도 특성을 보였다. This study was carried out to investigate the agronomical and physicochemical properties of five newly bred sugary lines in YARI (Yeongnam Agricultural Research Institute) that developed from the cross of sugary and Hwayeongbyeo, Hwasambyeo and Seomjinbyeo. Culmlength of newly bred sugary lines were longer than that of Nampyeongbyeo as $84.2{\sim}99.3cm$. However the weight of 1,000 grains and yield were lower than that of Nampyeongbyeo by two to three times. According to physicochemical properties, most of the new bred sugary lines showed low contents of amylose and mineral compare to normal varieties. And all sugary lines showed much higher amount of the sucrose and glucose contents compare to Nampyeongbyeo. Especially the sucrose content of newly bred sugary line, 55413, was 5 times higher than that of Nampyeongbyeo nevertheless, fructooligosaccharide and isomaltooligsac charide were not detected. The amylopectin constitution of sugary lines showed more chairs of DP (Degree of Polymerization)<12 but fewer chains of DP $13{\sim}24$ compare to Nampyeongbyeo. Newly bred sugary lines were lower viscosity in RVA (Rapid Viscosity Analysis).

The purpose of this study is to examine effects of a differentiated-previous notice system of assessment (DPNSA) on the mathematical achievement. For this purpose, the following problems are established. First, how differentiated materials of assessment are made and put to practical use, which are able to applied practically to the teaching of mathematics? Second, is there any difference in mathematical achievement between the experimental group which has carried into a DPNSA, and the control group which has not? This study was designed to use nonequivalent control group pretest- posttest design. Two fourth grade classes were selected from an elementary school in Chinju city for this study, one for an experimental group and the other for a control group. One calss has carried into a DPNSA and the other has not. In order to achieve the first purpose, analysis of a course of study and aim of mathematical subject are searched, and developing principles of materials for assessment and a standard plan of assessment are ready. In order to develop a DPNSA materials and throw them in the class repeatedly, teaching plans are organized and cooperative learning of small group and self-estimate are practiced during the class. The results obtained from the data analysis were as follows. There was a significant difference between the experimental group and the control group in mathematical achievement at the significant level of 0.1. That is, this research shows that there was an effects of a DPNSA on the mathematical achievement. The results are like theses. An experiment which has done a DPNSA showed better mathematical achievement than a control group which has not. The fact tells us that the DPNSA make pupils to enhance the mathematical power. By pro-supplying the affairs of problems to the pupils, this study helped to give the opportunity to solve the given problems easily to them. In the part of teachers, the result of assessment forced them to reconsider their teaching and to improve the method of teaching.

This study was carried out to investigate the histological origin of callus, clone, shoot, and root of Pinellia ternata(Thunb.) Breit, known as a medicinal crop. The results obtained were as follows: 1. Callus was induced from the cutted section of leaf tissue. 2. Shoot formed from the subepidermis of leaf explant. 3. Adventitious root were formed from callus tissue or base of shoots. 4. Contractile root forming root primodium was normal structure. 5. Shoot primodium was formed fast better than root primodium from meristemoid.
