This study is to examine the several basic wooden movable types molded in after the Japanese Invasion of Korea in 1592. The description begins with summarizing each basic history of movable types. The parts that have not been clearly defined are relatively dealt with in detail. Subsequently the existing movable types are examined as many as possible and arranged one by one. And through analyzing the elements used in these movable type names, it is examined which elements were preferred by the existing movable type names. This preference could be helpful for naming the newly found types or renaming the existing types. Next each standard name of movable types has been selected in total 10 movable types with applying writer's own selection standard. Those are as follows: 'Moongyepak mokwhalja(文繼朴木活字)', 'Naju mokwhalja(羅州木活字)', 'Chunki kyosoekwan pilseocheja(前期校書館筆書體字)', Injosillokja(仁祖實錄字)', 'Hyojongsilokja(孝宗實錄字)', 'Huki kyosoekwan pilseocheja(後期校書館業書體字)', 'Koansanggam seomyeong daeja(觀象監 書名大字)', 'Kyeongsejeongeumja(經書正音字)', 'Panghongmujeongwon daeja(倣洪武正韻大字)', 'Seomgaemuninlok daeja(剡溪門人錄大宇)'.

When investigating old, printed documents, determining whether a work is printed on a woodblock or using a movable metal type is crucial. It is because the history of printing in Korea and across the world relies on determining the relevant printing invention used and the time of use of the movable metal type. Deciphering details from woodblock and metal prints requires various kinds of information regarding the imprint and the work's printing background, such as information on the characters in the printed document, the outline of the pages, the type of ink used, the production period of the ink, and the production period of the Korean paper. Analyzing such information can generally reveal the production period and the methods used on the old document. However, as such information is not documented systematically, relying on the researcher's judgment based on their experience and perception becomes inevitable. This study conducted an experimental investigation of the printing characteristics of woodblock prints using a replicated woodblock of the Wanpanbon edition of the Shimcheongjeon. Subsequently, the various phenomena and characteristics appearing on the woodblock prints were documented for future reference to determine the printing method of old documents. Finally, woodblock novels without an imprint may be used as a reference to estimate the printing dates by determining the degree of wear on the woodblock.

Materials and Methods: Total number of peroneal perforator flap is 14 cases, which 10 cases were man, 4 cases were woman. The range of age was 12 years old minimally and until 63 years old. The trauma was most common etiology, which was like traffic accidents, 9 cases. We confirmed tibialis anterior artery patency by doppler flow meter, angiography as preoperative evaluation. Results: 1. The success rate was 91%, that in 14 cases, 13 cases were succeded. 2. To obtain successful result of peroneal flap, one must have the anatomic concept for vascular pattern, 8 cases were between peroneus muscle and soleus muscle branch type but, 3 cases were through soleus muscle branch type, so we treated these cases by using soleus muscle including peroneal perforating branch not to injury perforating artery directly. 3. The pedicle size was between minimally $2{\times}2.5cm$ and maximally $6.5{\times}8.5cm$ so we could treat large recipient site. 4. The pedicle length was between minimally 3.2 cm and maximally 11.5cm, average 7.5 cm. 5. The diameter of perforating artery was estimated by inspection, that was about 0.2-0.5 cm Conclusion: The peroneal perforating artery flap has merits that we can approach in avascular zone and has wide movable range from foot to distal femur and little donor site mobidity and can harvest osteocutaneous flap. The weak point was the irregular anatomy of nutrient artery and not to contain sensory nerve.

The ancient paper document we chose as a case study for our research is "One Hundred Poets of the Tang Dynasty", which is housed in the Ryukoku University Library. The purpose of this research is to introduce a method to analyze the surface roughness and microstructure at a high resolution. In addition, we attempt to quantitatively measure the surface unevenness of the types and curve structure. We used a tridimensional digital microscopy as a non-contact and a non-destructive method to study ancient cultural paper. The information contained in the paper may be lost in the process of applying strong pressure to clean and lining or press. However, this microscopic measurement method can non-destructively analyze a large amount of data in old printed books. Moreover, it enables observing them directly with reflected light. Therefore, this method may be useful for collecting printed information remaining on the surface of the paper.

Purpose: Basal cell adenoma of the salivary gland is an uncommon type of monomorphic adenoma. The most frequent location is parotid gland. It usually appears as a firm, mobile and slow-growing mass. Originally the term "basal cell adenoma" is described as a benign salivary gland tumor comprised of uniform appearing basaloid cells which are arranged in solid, trabecular, tubular, and membranous patterns. But the myxoid and chondroid mesenchymal like component as seen in pleomorphic adenoma is lacking in basal cell adenoma. We report a case of basal cell adenoma of parotid gland with review of the literatures. Methods: The 59-year-old female patient was referred to our department with a painless palpable mass in the left preauricular region for about 1 year. Movable and nontender subcutaneous mass was palpable. There was no evidence of cervical metastasis in computed tomography and ultrasonography. On fine needle aspiration cytology, pleomorphic adenoma was suspected. Under general anesthesia, superficial parotidectomy including tumor was performed. The biopsy result was basal cell adenoma. Results: Long-term follow-up for 54 months showed favorable result without evidence of recurrence except for temporary facial nerve weakness right after the surgery. Conclusion: Basal cell adenoma is the third most frequent benign tumor of the salivary gland, following pleomorphic adenoma and Warthin's tumor, although the incidence is low. The typical clinical feature of the basal cell adenoma is slowly growing, asymptomatic, and freely movable parotid mass. Basal cell adenoma should be also considered as a differential diagnosis of the parotid gland benign tumor.

The papilloma of the nose and the sinuses is uncommon benign neoplasm that was pro bably first described by Billroth in 1855 as a "villiform cancer": It may polypoid or papillomatous in the nose or sinuses and is frequently multiple. Clinically, there are 3types of the papilloma found in the nasal cavity and sinuses, vestibule, fungiform, inverting. The vestibular type is the keratotic lesion arise from the squamous epithelium lining the vestibule of the nose. The inverting type, which is covered by the columnar or metaplastic squamous epithelium is pliable, pink and tends to bleed quite easily. The fungiform type is covered by the stratified squamous epithelium which shows varying degree of cornification. It is more caulflow like than the inverting type and does not bleed easily. Recently, the authors experienced a case of the fungiform type papilloma which occupied right nasal cavity and nasopharynx. So, we reports the case, with review of the current brief literatures. A 55 year old man was admitted with the chief complaints of right nasal obstruction by the protruded movable mass on right nasal cavity, which was noticed about 7 months ago. The biopsy report revealed fungiform type papilloma.(length 18cm. width 2.5 cm. weight 41 gr.) The tumor mass was removed surgically through intranasal approach under the general anesthesia. Postoperative course was uneventful and the patient was discharged after 7 days hospitalization. No evidence of recurrence has been observed up to date.

Purpose: Myoepithelioma is a rare tumor that originates exclusively from myoepithelial cells of the salivary glands, breast and the prostate. Myoepithelioma accounts for less than 1% of all salivary gland tumors. The objective of our study is to present our experience of the infra-auricular mass which was finally diagnosed as a myoepithelioma. Methods: A 54-year-old woman was presented with a firm, movable, slow-growing infra-auricular mass with 3 cm in diameter. MRI scans and fine needle biopsy was performed for preoperative diagnostic study. A superficial parotidectomy was preceded and removed tumor successfully. Results: Histopathological study revealed a myoepithelioma of plasmacytoid type. Patient's postoperative course was uneventful without any complication and had no evidence of recurrence of tumor for 9 months follow-up period. Conclusion: Myoepithelioma in the parotid gland shows similar clinical courses and intraoperative finding to the pleomorphic adenoma and superficial parotidectomy was selective choice for treatment.

As the number of children's libraries has increased in Korea, it has been discussed to improve the quality of design in the libraries. In a reading room of children's library, spatial consideration should be focused on the children under 10 years old since they are in important points to learn Hangul and to develop reading habits. This study is aimed to examine the characteristics of a floor-sitting reading room, where children can feel like a home, stay in clean and safe and play while reading. The seven case studies of floor-sitting reading rooms are analyzed from the viewpoint of each factor of physical environment, including structure, furniture, and decoration. The following is the summary of findings of this study. First, floor-sitting reading rooms tend to compose main reading areas around bookshelves. Reading areas create the characters by changing floor levels and arranging furniture associated with windows, columns, and wall-type bookshelves. In the reading areas, movable low-level tables are frequently placed for flexible space uses, and seats for reading tend to put together with fixed bookshelves. Second, the central areas of the reading rooms are often shaped in the forms of pods, storytelling areas, sculptures, and unique furniture. Especially storytelling areas and pods play the cores of the reading rooms with the varying steps of floors and pictorial graphics on walls. Third, decoration elements in the reading rooms are designed with graphics, visual displays, and sculptural decorations. In my case studies, spatial elements such as reading nooks, attics, tunnels, and shelters are not often found in the floor-sitting reading rooms even though children like to have them. Since it is the advantage of floor-sitting reading rooms where children can take off shoes and act freely, we should look for the design of such spatial elements in the floor-sitting reading rooms.

The pilomatricoma (calcifying epithelioma of Malherbe) is rare benign hard, spherical and freely movable cutaneous tumor, which was differentiated from hair cells, particulary hair cortex cells. It is usually occured as a single, asymptomatic, 0.5 cm to 3.0 cm sized, deep seated, firm nodule, covered by normal or pink skin. It arises chiefly in young people, including children, and most often in the head, neck and upper extrimites. The authers experienced a case of pilomatricoma which occured in preauricular region. This case was summarized as follows. 1. 10 years old female has suffered from hard subepidermal mass on preauricular area and she visited our out patient clinic. So we performed surgical extirpation and the excised specimen was pathologically examined. 2. Grossly the tumor measures 2.0 cm in diameter and firm, bosselated, spherical shaped which covered by a thin layer of fibrous tissue. On cut section, it shows spicular gritty surfaces, well encapsulation, interwoven and keratotic lamellae. 3. Histopathologically, the epithelial masses of the tumor are composed of two type of cells, basophilic cells and shodow cells. The basophilic cells resemble hair matrix cells which posses round or elogated, deeply basophilic nuclei and scanty cytoplasm. The shadow cells show a central, unstained shadow at the site of the lost nucleus. Gradual development of basophilic cells into shadow cells can be observed. Foci of calcification are present within the lobule of shadow cells. The stroma of the tumor shows a considerable foreign body giant cell reaction adjacent to the shadow cells. 4. No recurrence was observed until post-operative 40 months.

The history of printing technology in Korea is studied by investigating existing ancient documents and records and comparing accumulated data and knowledge. Cultural property research requires non-destructive testing and observation with the naked eye or aided by a microscope. Researchers' experience and knowledge are required even though they cannot guarantee the outcome. For ancient documents and records that are presumed to consist of woodblock printing, wood type printing, metal type printing, or their combinations, each researcher draws various opinions and conclusions. This often causes confusion and divides the opinions of ordinary citizens and field specialists. Among them, the criteria for judging ancient documents or books printed using woodblock and metal movable material are ambiguous. Academic research on the development history of printing technology in ancient Korea has been stagnant, and conflicts among researchers have also erupted. Involvement of national investigative agencies not specialized in cultural properties has exacerbated the situation. In this study, we investigated printing characteristics that are likely to serve as more objective judgment criteria by quantitatively analyzing the experiments of retrieving several sheets of Korean paper (Hanji) using a replicated Hunminjeongeum (訓民正音) woodblock and quantitatively analyzing the images of the printed papers. In addition, the validity and questions for the typical phenomena presented as a method for distinguishing between woodblock and metal print are reviewed. We investigated the possibility of developing new objective judgement criteria through quantitative analysis using image analysis and investigating the printing characteristics of Korean paper through a reproduction experiment of woodblock printing.
