  • The aim of the present study was to investigate a relation between occlusal wear area and occlusal contact patterns. For the purpose, occlusal wear area were measured in 58 dental students and in 129 patients with temporomandibular disorders(TMDs) from dental casts. Teeth used in this study were from canine to second molar on both sides in upper arch, totally ten. Occlusal wear area on casts was marked by pencil and photocopies, and then, the area was measured with planimeter. Occlusal relation was clinically examined with regard to Angle's classification, chewing side preference, lateral guidance pattern and bruxing and/or clenching habit. T-Scan, electronic occlusal contact analyzer, was used to record occlusal contact number, contact force, contact time and occlusal balance that is TLR(total left-right statistics) during tooth contact. All measurement were repeated 3 times and the average value was used for data processing. The obtained results were as follows : 1. Mean value of occlusal wear area did not differ significantly between dental students and patients. 2. There ws not significant difference in wear area between chewing side and non-chewing side in both groups. 3. Occlusal wear area was significantly increased with age in both groups. 4. Three subgroups divided by Angle's classification did not show any difference in occlusal wear area among them, but three subgroups divided by lateral guidance pattern showed slightly significant difference between canine guide subgroup and group function subgroup in patients. Occlusal wear ares\a in group function subgroup wear larger than canine guide subgroup. 5. Mean value of wear area in patients with bruxing and/or clenching habit did not differ from those in patients without such habit. 6. Correlationship among items related to occlusal contact pattern were highly consistent and significant in dental students and only one item significantly correlated with occlusal wear area was tooth contact time.

  • This experiment was investigated to effect of divided rhizome size and medium type on survival rate and growth of wasabi for 60 days in controlled growth room. In divided rhizome size of 5mm above, survival rate was 100% and their growth (plant height of 12cm and leaf number of 3${\sim}$4 per plant) was good at 30 days after wrapped-sphagnum treatment. Plant height was 20cm above and number of leaves increased in 1-2 per plant at 60 days after treatment. Survival rate and growth didn't show any effect on plant regulator of root-tone. In inorganic media (saprolite and aerated light stone) treatment, survival rate of wasabi in divided size of 5${\sim}$10mm showed 83% or above at 30 days in deep flow culture. Growth did not show significant difference of inorganic support media treatments. Therefore, it is possible for divided rhizome size of 5mm above to do production of seedlings by acclimatize for 30 days in hydroponics under controlled growth chamber.

  • Purpose: This study is executed to examine the effects of Korean somatotype on energy consumption and hormone changes during treadmill gait. Methods: The objects of study were a total of 70 university students in their 20s and 30s divided into 7 groups according to somatotype with 10 members each, 4 groups of male (M1, M2, M3, M4) and 3 groups of female (F1, F2, F3). Results: In case of male groups, there was a significant difference in VO2 and VCO2 between group M1, M2 and M3 (p<0.05). There was also a meaningful difference between Phase1 and Phase2, Phase3 and Phase4 in a phase (p<0.01). In case of female groups, there was a meaningful difference in VO2 between F1 and F2, F3 (p<0.01). There was also a significant difference between Phase1 and Phase2, Phase3 and Phase4 in a phase (p<0.01). There was no significant difference in VCO2 among them, but there was a significant difference in it between Phase1 and Phase2, Phase3 and Phase4 (p<0.01). There was equally no significant difference in the concentration of adrenaline and nor-adrenaline among both male and female groups, but such concentration showed meaningful difference before and after exercise (p<0.01). Conclusion: Energy consumption differs according to somatotype. There is a difference in hormone change, indicating that somatotype has effects on the physiological change. Therefore, in future exercise should be executed in more diverse conditions to further study somatotype with energy consumption and the correlations of hormone change.

  • Background: This study investigated the effects of face-to-face and non-face-to-face McKenzie exercises and elastic band strengthening exercises on falls and fitness in older adults. Methods: A total of 44 subjects were divided into a face-to-face group (FG; n=22) and a non-face-to-face group (NFG; n=22) who met older adults. Both groups used McKenzie exercises and strength training with elastic bands The fall efficacy scale (K-FES) and glycosylated hemoglobin (HbA1c) Pro were used to compare the senior fitness test (SFT). Results: No significant differences were detected between the two groups before the intervention; however, a significant difference was noted in the K-FES scores after the intervention. The change in HbA1c after the intervention was not statistically significant in the FG or the NFG, and no significant difference was detected between the two groups. The change in lower limb muscle strength in the elderly physical fitness test showed no significant difference between the two groups before or after the intervention. The change in upper limb flexibility after the intervention was not significantly different in the FG or NFG, indicating no significant difference between the two groups. The change in the 3-meter round-trip test after the intervention was significantly different in both the FG and NFG groups, but the difference between the groups was not statistically significant. The change in the grip strength test of the dominant hand showed no significant difference after the intervention in the FG or the NFG, and the difference between the FG and NFG groups was not statistically significant. The dominant foot external standing after the intervention was significantly improved in the FG, but no significant difference was detected in the NFG, and the difference between the two groups was not statistically significant. Conclusion: The study findings revealed that FG and NFG McKenzie exercises and elastic band strengthen exercises were equally effective at preventing falls and improving fitness in older adults.

  • This study aimed to investigate the effects of somatotypes and body-related variables such as body exposure and body satisfaction on underwear evaluative criteria. Usable questionnaires were obtained from a total of 250 male and female students in their 20s. The data were mainly analyzed by t-test, ANOVA and analysis of variance using SPSS ver. 21.0. The results of this study are as follows: First, differences between underwear and outerwear evaluative criteria were found. For example, size, comfort and washing were important for the underwear but design, brand and fashionability were meaningful for outerwear. Price, color, material, and sewing were important for both outerwear and underwear. Second, the groups divided by somatotypes, a thin person group, a moderate person group and a fat person group, showed no difference in underwear evaluative criteria. Members of all the somatotype groups evaluated underwear similarly. Third, the groups divided by body image distortion showed different evaluative criteria for underwear. The negative discordance group emphasized the importance of the practicality factor, but the positive discordance group stressed the significance of the symbolism factor. Finally, the groups divided by body exposure and body satisfaction showed different evaluative criteria for underwear, too. The effects of socio-cultural variables on the underwear evaluative criteria proved to be significant.

  • This study was undertaken to investigate the degree of asymmetry in each part of the head in skeletal craniofacial asymmetric patients, and secondarily to determine the nature of difference existed between asymmetric patients and normal persons. The subjects consisted of 49 asymmetric adult patients and 52 normal adults, and the average ages were 21 years 5 months and 23 years 5 months, respectively. The computerized analyses of 33 linear measurements, 12 angular measurements, and 8 surface areas from posteroanterior cephalometric radiograph were carried out. The conclusions were as follows; 1. Asymmetry was a common finding in both normal and asymmetric group. 2. When the analyses were undertaken after the head was divided into 3 parts anteroposteriorly and superoinferiorly in the asymmetric patients, there were significant asymmetries in all parts excepts in the cranial base region. 3. When the analyses were undertaken after the head was divided into respective 3 parts anteroposteriorly in the asymmetric patients, the more posterior part showed relative stability than the more anterior part. 4. When the analyses were undertaken after the head was divided into 3 parts superoinferiorly in the asymmetric patients, the more superior part showed relative stability than the more inferior part. 5. Twelve variables indicating asymmetry were selected and the highest ranked variable was Me-Mid-sagittal reference line.

  • This present study tried to observe an each feature that the difference of Neijing(內經) and Nanjing(難經) descriptions about the three-portion and nine-position pulse taking(三部九候脈). It was interpreted and contradistinguished that discrimination of position, diagnosis object, and the perceptions of Earth of the center among the Five Phase of each literature were described in Neijing and Nanjing for the three-portion and nine-position(三部九候). In Neijing, the three-portion and nine-position method divided three parts the whole body. Then the each three parts again divided with Heaven, Earth and Man(天地人). About the corresponding parts of pulse diagnosis, there mentioned for the head and the Zang-Fu organs(臟腑), but not mentioned for the hand and foot. In addition, Earth is assigned to the Earth(土), an each Earth accounted for the source of life. In Nanjing, three-portion divided Chon, Gwan, and Cheok(寸關尺) and each spots separated three stage of pulse taking. For the pulse taking spots and diagnosis, there mentioned the hand and foot instead of the unclear mention of Zang-Fu organs. Then Gwan spot and middle stage of pulse taking were assigned to the Earth, respectively. It was emphasized stomach Qi(胃氣) that the region of Earth, Gwan spot and middle stage among the pulse taking spots each literature were described in Neijing, Nanjing.
