This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

We have used molecular biology technique to label the side chains and backbone of HBV preS1(1-56) with stable isotope (??) during E. coli over-expression and purified the protein to near homogeneity. The expression level of ?? labelled preS1(1-56) seems to be ∼15% of the total protein. to characterize the secondary structure of the labelled protein, circular dichroism was used. In different buffer conditions including pH 3.3 and pH 7.4 the protein seems to be devoid of any stable secondary structure probably suggesting that the N-terminal portion (preS1(1-56)) of HBV preS1 might be unstructured before binding to its target cells.

Onlay graft of the calvarial bone has been popularized in craniofacial surgery because absorption of the calvarial bone is less than that of the endochondral bone. But the problems with using the calvarial bone are its rigidity and difficulty in setting a precise apposition. When the outer tables of the calvarial bone are used for augmentation and reconstruction of the convex zygoma, forehead, or chin, it is better to place the cancellous surface over the convex recipient bone to get a precise apposition. Whereas, it is better to place the cortical surface over the concave nose or orbital cavity to achieve a good apposition. Therfore, our study was designed to determine the differences of bone absorption and regeneration between cancellous and cortial bone contact to facial bone, and between preserved periosteum and detached periosteum in autograft of calvarial bone in dog models. Outer tables of the calvarial bone were placed in subperiosteal pockets of the upper and lower maxilla in four different ways : Group I ; The cancellous surface was placed in contact with the bare recipient bone, and the cortical surface attached with periosteum was accordingly contacted with the elevated periosteum of the recipient bone. Group Ⅱ ; The corical surface attached with periosteum was placed in contact with the bare recipient bone and the cancellous surface was contacted with the elevated periosteum of the recipient bone, Group Ⅲ ; The arrangenent was similar to Group Ⅰ except that the periosteum of the graft was deprived. Group Ⅳ ; The arrangement was similar to Group Ⅱ except that the periosteum of the graft was deprived. Volume measurements using a caliper technique and histological study were made 20 weeks postoperatively. The volume of maintenance is as follows ; Group Ⅰ, 84.2% ; Group Ⅱ, 77.6% ; Group Ⅲ, 77.0%, and Group Ⅳ, 69.5%. The histolgical contribution of living bone was assessed by a modified point counting technique : Group Ⅰ, 86.6%, Group Ⅱ, 83.8% ; Group Ⅲ, 79.6% and Group Ⅳ, 77.6%. Greater volume maintenance and histological contribution of living bone were found when cancelllous surface rather that the cortical were placed in contact with the recipient bone and the grafts from their periosteum were preserved. We concluded that in order to expect better survival of a grafted bone, the cancellous surface of the graft should contact with the recipient bone and that the periosteum of the graft should be preserved.

This research aims to study origin by trace elements (Cu, Cr Pb, Ni, Mn, Li,Zn) of 225 samples of the gneisses that receive high metamorphism in sannae-myeon area, Namwon-gun. I have studied average abundance, abundance range and frequency distribution of each elements, and considered geochemical feature of the trace elements in the shale and granite. Abundance of Cu, Cr, Ni, in the shale of sedimentary origin is higher than that in the granite of igneous origin. Abundance of the trace elements in the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is very similar to the that in the shale with the biotite gneiss, but that in the leucocratic gneiss is less than in the shale and it is similar to the granite. Frequency distribution of the rocks of sedimentary origin is irregularly widely dispersion, but that of igneous origin is distributed narrowly around maximum frequency. Therefore the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is paragneiss with the biotite gneiss, and the Leucocratic gneiss is orthogneiss. This result is in accord with geological field survey and study on the metamorphism(Kim O.J. etal.,1964;Kim H.S., 1970,1973; Lee S.M., 1980,1981)

Bony depression in the face may occur doe to congenital failure of development trauma or excessive surgical resection. Various materials, autogenous bone, autogenous cartilage and silicone rubber have been employed for bony contour restoration. Since autogenous bone grafts become consolidated with the underlying recipient bones, the incidence of extrusion or deviation of the graft is much fewer. But they may be easily fractured at the time of carving because of their rigidity. Autogenous cartilage grafts do not require contact with the nasal bony framework, but they tend to curl and bend. Using silicone rubber is a simple and fast procedure, but the prosthesis itself is a foreign body which causes occasional foreign body reaction or exposure of the prosthesis. Therefore, the materials, which have such nature as consolidation, complete contact and convenience without complication are considered to be ideal for augmentation of the bony depression. It may be an ideal material for prevention of the complication of the implants, if a new bone formation at the gratted periosteum wrapping the silicone rubber implants develops. To confirm the possibility, biological test with dogs was initiated. Six samples of periosteum and fascia wrapping the silicone rubber implants, respectively were collected from 9dogs at 8, 16 and 24 weeks. Grossly, difference between translucent periosteum and whitish fascia was noticeable at 8 weeks after implantation. However, it is difficult to distinguish between fascia and periosteum at 24 weeks. Histologically, fibrous capsule developed at 8 weeks and there was a marked thickening at 24 weeks on both periosteum and fascia. At one of 6 samples of 24 weeks periosteum, wrapping the silicone rubber implant, formed a new bone. In conclusion it is possible for the grafted periosteum wrapping the silicone rubber implants to make a new bone. Therefore the periosteum and fascia wrapping the silicone rubber are well taken at the recipient site. Also, they play a good role of barrier against exposure of implant. Especially the periosteum is better than the fascia, because of its bony formation and easier obtaining

Necrotizing fasciitis is defined as infectious disease showing extensive necrosis of the superficial fascia with widespread involvement of the surrounding tissues and concurrent systemic toxicity. It is found commonly in the extremities, the trunk and the perineum, but shows extremely rare occurrence in the well vascularized area such as head and neck area. Occurred in the head and neck area, it is called "cervicofacial necrotizing fasciitis" (CFNF). It is a fatal disease which carries a mortality rate up to 60%. Early diagnosis, aggressive surgical debridement of necrotic tissues and massive antibiotics therapy are essential for achieving a favorable outcome. We present a case of cervicofacial necrotizing fasciitis in 35-year-old male patient with literature review.

1. The purpose of this study is to reflect reality of sports to legal structure. This author classified types of sports related accidents as match accidents, school accidents, leisure and living sports accidents. Out of such accidents common factors such as 'the provider of virtue' and 'user' could be deduced and this author reviewed what kinds of obligations must be shouldered by these people respectively. In particular this author stressed the fact that disproportionate emphasis is placed on malfeasance in disposition of dispute over the sports accidents. Malfeasance is a method for seeking relief through money after the accident. However default in an obligation enables supplementary completion when it is not performed or imperfectly performed. Thus if object which must be performed is providing safety then it is possible to secure safety prior to accident. Furthermore at such time mistake of the debtor can not become a factor. For this reason this line of thinking has the following merits: (1) In comparison with constitution of malfeasance default of an obligation has long prescription. It seems that such fact was a motivation for saving obligation for safety consideration by making it fall under the principle of faith. (2) Default of an obligation is not an obligation for ordinary attention which is cause of malfeasance but it takes up issue with obligation for attention required for performance. Game organization, sponsor and spectators etc. shares certain sense of identity and are demanded to have manners. As method for evaluation of such relationship of faith it may be possible to impose a special kind of obligation for attention and it will be close to constitution of default of an obligation. (3) Imposing obligation for provision clarifies that such responsibility belongs to game organizations promoting sports to which anyone can participates or to national or public organizations, sponsor, schools which induced such sports as a part of its educational programs, installer who made people use it as leisure facility or person in charge for its management. (4) It is also applicable to umpires, players or spectators who use field of sports. It is possible to reflect reality whereby these people specifically relate themselves to sports. In consequence it will be possible to make people feel the necessity of expanding the principals of sports from 'doers' to 'watchers.' (5) The obligation of provision is an obligation under the principle of faith therefore mutual negotiation may be expected to clarify such fact. It may be also evaluated by effectuation of users' self-determining right. 2. If the above mentioned structure is provided then, although it is limited to sports, students who are subjects of instruction, seminar attendants, and furthermore players who finished games may be obligated to bear responsibility for safety consideration under the principle of faith. Accordingly level of relief for considerable number of victims may be increased as cases of treating even borrowed materials as default of obligation being expanded. 3. As scope of responsibility becomes more clearer it will be possible to prevent disputes while securing more safety as rules and regulations become more clearly enacted or new contract is signed or existing contract is revised.
