To assess the comfortableness of climbing wear, this study investigated physiological responses and subjective senses by dividing the enveronmental condition into 2 types, climbing wear into 2 types and subjects into 2 groups. The indicators of physiological responses included clothing temperature by region of the body, average skin temperature, eardrum temperature, temperature and moisture whitin the clothing, the amount of sweating, heart rate, energy metabolism. The indicators of subjective senses included the sence of warmth, the sense of humidity and the sense of comfortableness. This study has the following limitations : First, only representative specimens were selected from diverse functional materials and general materials and tested. Care was taken not make an expansive interpretation of the study results. Second, climbing exercise has no special rules. Therefore, a little more diverse and extensive studies are needed in the future. Third, the state of the artificial climate room might considerably differ from the climate of the general mountainous terrain. Therefore, the laboratory researchmight be more or less different from the research under the actual environment. With these limitations in mind, the climbing wear of general materials and the climbing wear of functional materials were investigated by environmental condition and by group of subjects. As a consequence, the following findings were obtained : (1) Physiological Responses As for the skin temperature by region of the body, the skin temperature of the trunk was higher than that of the limbs. The average clothing temperature showed the temperature distribution of 31.08℃∼33.38℃ and higher than that of skin temperature. The higher temperature/moisture were, the higher this distribution of skin temperature was shown to be. The eardrum temperature was shown to be within the distribution of 36±1℃. It was found that there was not a great difference in int under the different environment because of the ability of the body to regulate its temperature. In the 'A' environment(18℃, 40%), it was found that there was a significant difference in temperature/moisture wihtin clothing between the types of climbing wear at the significance level of p <0.001. In the 'B' environment, it was found that there was not a statistically significant difference. This indicates that there was not a great difference between the climbing wear of general materials and the climbing wear of functional materials in the hot and humid environment. As for the amount of sweating by reginon of the body, the sweating amount of the trunk was higher than that of the limbs. The sweating amount of the chest and the back was shown to be highest. And the difference between the types of climbing wear showed the same tendency as the climate within climbing wear in both the 'A' environment and the 'B' environment. Therefore, they had the close relationship with each other. The higher the temperature/moisture of the environmental condition became, the higher blood pressure became. Depending on time, blood pressure tended to rise at a time of exercise and fall at a time of resting. The lowest blood pressure belonged to the normal domain, but the highest blood pressure was shown to be high at the range of 1㎜Hg∼10㎜Hg. (2) Subjective Senses It was found that there was not a difference in the sense of warmth between the climbing wear of general materials and the climbing wear of functional in both the 'A' environment(18℃, 40%) and the 'B' environment(25℃, 60%). There was a more or less difference in the sense of humidity and the sense of comfortableness in the 'A' environment condition. But it was found that there was not a difference between climbing wear of general materials and the climbing wear of functional materials in the 'B' environment(25℃, 60%). (3) The Study Results Depending on the Classification of Subjects It was found that there was a difference in the result of physiological reactions by item between the group of climbing specialists(P1) and the group of general people(P2), which indicates that physiological reactions are related to exercise ability at ordinary times. But, in case of the group of climbing specialists(P1), there was not a great difference in the figures of subjective senses between and the 'B' environmental condition. But in case of the group of general people, it was found that there was a more or less difference between the types of wear materials in each environmental condition. It was found that the group of general people was sensitive to changes in wear materials.

The ectomycorrhizal fungus Tricholoma matsutake grows symbiotically with Pinus densiflora. Phenylalanine ammonia-lyase (E.C. 4.3.1.24) catalyzes the conversion of L-phenylalanine to trans-cinnamic acid. The role of fungal phenylalanine ammonia-lyase, however, has not been clear until now. In this study, the gene encoding phenylalanine ammonia-lyase (PAL), which was isolated from T. matsutake, was cloned and characterized. The PAL gene (tmpal) consists of 2,160 nucleotides, coding for a polypeptide containing 719 amino acid residues. The deduced amino acid sequence of tmpal from T. matsutake shows high identity (70%) with that from Laccaria bicolor. Comparative analysis of the PAL genes among T. matsutake and other species of the class Agaricomycetes showed that both active sites and binding sites were significantly conserved among these genes. The transcriptional analysis of the PAL gene revealed a differential gene expression pattern depending on the developmental stages (mycelium, primordium, stipe, pileus, and gills) of T. matsutake. These results suggest that the PAL gene in T. matsutake plays an important role in multiple physiological functions.

This is a series of continuing research on facial bone fractures of Koreans worked by Dept. of Oral and Maxillofacial surgery, Dental College of Yonsei University, Seoul, Korea, since 1972. The study was based on a series of 630 patients with facial bone fractures treated as in patient at Yonsei Medical Center, Yonsei University, during the period of Jan. 1982 through Dec, 1987. The results obtained are as follows: 1. The ratio of Men to Women was 4.3 : 1, and admissions for facial bone fractures have been increased year after 1984. 2. The age frequency was highest in the third decade(38.3%). and fourth, second, fifth decade in orders. 3. The traffic accident was the most frequent cause of facial bone fractures(51.3%). 4. The most common location of facial bone fractures was the Mandible(35.3%), and Zygoma complex(29.8%), Nasal bone(15.0%), Maxilla(11.0%) were next in order of frequency. 5. In 291 patients of Mandible fractures, 226(77.7%) had fractures only in Mandible and 65(22.3%) had another facial bone fractures. The most frequent fracture site of mandible was the Symphysis(43.0%) and Angle(22.4%), and Simple fracture was the most frequent in type of fracture(66.9%). Intermaxillarty fixatin & Open reduction was major method of treatment(36.9%). 6. In 394 patients of Midface fractures 323(82.0%) had fractures only in Midface and 71(18.0%) had another facial bone fractures. The most frequent site of Midface fractures was zygoma complex & zygomatic arch(42.7%), and Simple fracture was the most common type of fractures. Observation(Maxilla :44.2%, Zygoma :51.0%) and Open Reduction(Maxilla :20.0%. Zygoma :23.5%) were the major method of treatment. 7. The frequency of Nasal bone fracture was about 1/5 of Midface fractures, and Closed Reduction(42.2%) was the major method of treatment. 8. The complication was reported in only 16 patients, and Malunion was the major complication. 9. Head(44.4%), Lower extrimities(14.5%) and Eye(12.3%) were injured commonly with facial bone fractures. 10. The elapsed time from injury to hospital was within 24 hours in 73.8% of patients, however 15.5% of patients arrived the hospital 72 hours after injury.
