Background: There is an opinion that improper postures of the head and cervical spine are associated with temporomandibular joint (TMJ) disorders (TMDs). Objects: The aim of this study was to investigate the proportions among the cervical kyphotic angle, physical symptoms including the pain intensity level of the TMJ, and severity of TMD disability in patients diagnosed with TMD. Methods: Sixty-two subjects participated in the study. The evaluation tools included measurements of the cervical kyphotic angle based on the Ishihara index, pressure pain threshold (PPT) on the TMJ, maximal mouth opening (MMO) without pain, current pain intensity level of the TMJ measured using the Quadruple Visual Analogue Scale (QVAS), Korean TMD (KTMD) disability index, KTMD Symptom Frequency/Intensity Scales (SFS/SIS), and Korean Headache Impact Test-6. Correlation analysis was conducted to investigate the correlations between the cervical kyphotic angle and parameters related to TMJ symptoms. Results: Variables that were significantly correlated with the cervical kyphotic angle were the PPT around the TMJ (r = 0.259, p < 0.05), current pain intensity level of the TMJ based on the QVAS (r = -0.601, p< 0.01), and usual pain intensity level based on the SIS (r = -0.379, p < 0.01). The level of TMD functional disability was significantly correlated with the degree of headache (r = 0.551, p < 0.01), level of PPT of the TMJ (r = -0.383, p < 0.01), pain-free MMO (r = -0.515, p < 0.01), pain intensity level of the TMJ based on the QVAS (r = 0.393, p < 0.01), TMD symptom frequency (r = 0.739, p < 0.01), usual pain intensity of the TMJ (r = 0.624, p < 0.01), and most severe pain intensity of the TMJ (r = 0.757, p < 0.01). Conclusion: There is a positive correlation between the cervical kyphotic angle and PPT and a negative correlation between the current and usual pain intensity levels of the TMJ. The cervical kyphotic angle was a predictor of the pain level, tenderness threshold, and intensity of pain in the TMJ.

In May 1987, 11 clay icons and other stone products were excavated in an abandoned ancient tomb which was located in 541-1 Hwangsung-dong, Kyungju. 6 clay figures of them were depicted realistically man's features and postures, costume at that time that they gave a lot of significance to the fields of Korean Costume's Academic Society. The main purpose of this thesis is to study the background of costume history when it was made and its formal characteristics with the study of those 6 clay figures. Shilla accepted the customs and attires of Sui and T'ang by means of frequent in coming and out going Chinese envoy as well as Shilla's envoy, monks, hostages, and students in China. From that period, the diversity of Shilla's costume began to develop by introducing Tang's style into Shilla's costume. Crested hat of men's clothing of the clay figures in Hwangsung- Dong is Bokdu Men's figure II wore Bokdu which Hugak is attached to Byunhyung. The garment is a Po and it is a tight sleeve and silhouette's Banryungpo. The horizontal line of hemline of men's figure 1 can be presumed by expression of Ran though it is not as accurate as the clay figues in Yongg-ang-Dong. As for torso part 1, it can not be known the style of the crested hat because the head part was damaged, but it were shoes, belt and common sleeve, Banryungpo on tight sleeve shirt and tight trouser. The hair style of the women's clothing in Hwangsung-dong clay figure is Bukkye peculiar to Korea. The costume was slim silhouette that people wore tight sleeve and short blouse and long skirt and belted on their bosom which dresses style was in vogue from late Sui dynasty to the early years of the Tang period. The silh ouette of slim silhouette's high waist which can be seen in the women's dresses is mainly worn by Chinese and affected Shilla's costume. Therefore the dresses style of the clay figures in Hwagsung-Dong, it is considered it is a dresses style of tight sleeves and slim silhouette together with the adaptation and abolition of foreign elements on the basis of Shilla's own elements like Bukkye hair style and tight sleeve and silhouette. The style of Yonggang-Dong's clay figures expresses spherical gei and common sleeve, loose silhouette of flourishing Tang's costumes planly whereas the style of Hwangsung-Dong's clay costumes expresses refined spirit of the Shilla(Shillaism) though it is extremly simple.

In this study, an assistive device for BVM (Bag Valve Mask) was developed. When emergencies occur, rescuers must perform artificial respiration within four minutes utilizing suitable BVM. If not, the patient can suffer serious damage within their brain and body systems. The rescuer must execute artificial respiration until the patient arrives at the hospital. In the process of artificial respiration, the rescuer can feel fatigued in their forearm muscles, particularly those who may have smaller hands or weaker muscle strength. Many products have been developed to solve these problems, but these products are difficult to market and commercialize because of their volume, size, and difficulty of use. In this paper, the BVM assistive device that has been previously manufactured was improved, and an attempt was made to devise a new method that reduces the burden on the user. The BVM assistive device can be divided into three-parts: a head part for compressing the air bag, which can control the amount of air; the body part for coupling with BVM; and finally, the handle that can rotate for better use on various postures of patients. Throughout the experiment, the assistive device could inject an equal amount of air into the patients. As a result, the rescuer could feel less fatigue and inject a suitable amount of air to emergency patients during artificial respiration.

This study was designed to determine the effect of gestation housing and parity on the farrowing performance and behaviour of sows during pregnancy, farrowing and lactation periods. Total 18 Duroc sows were randomly assigned after 4 weeks of gestation to either an individual gestation stall or a groups of three with pen gestation system for three parities(1st, 2nd${\sim}$3rd, and 4th${\sim}$5th). Approximately 7 days before predicted farrowing date, sows were transferred to farrowing crates where they remained until 21 days post-partum. Behaviour was recorded on day 60 and 90 of pregnancy for 24 hours, on day of farrowing for farrowing duration and on day 10 of lactation for 2.5 hours in the farrowing crate. The results obtained from this study were summarized as follows: On 60 and 90 day of pregnancy, all sows in both groups made attempts for ventral lying more than for other postures. Sows in the group gestation pen spent more time on walking than those in individual gestation stall(p<0.01); however, the group housed sows were spent less time on drinking than the individually housed sows(p<0.01). There was no significant difference between gestation housings in the occurrence of stereotypy of pregnant sows. On day 60 of pregnancy, sows in the individual gestation stall showed the highest frequency of vacuum chewing and head weaving. However, floor licking and bar licking behaviours were highest in day 90 pregnant sows individually housed. The sows individually housed during the gestation period spent more time on sitting and eating on the day of farrowing in the farrowing crate than the sows group housed. On day 10 of lactation in the farrowing crate, the group housed sows during the gestation period made significantly more attempts for ventral lying than sows individually housed. In conclusion, the occurrence of stereotypy of sows during the gestation and lactation did not differ between gestation housings and farrowing performance of sows during the gestation period was not affected by gestation housing. Thus, the group housing for pregnant sows is a feasible means to improve welfare of sows and to increase the normal behaviour of sows.
