PURPOSE: This study examined the effect of muscle thickness of the deep cervical flexor muscle, muscle tonicity, and muscle fatigue of the superficial cervical flexor muscle by applying a functional latex pillow to patients with chronic cervical pain. METHODS: An experimental group using a functional latex pillow and a control group using a general pillow were assigned randomly to 30 people. Each pillow was applied in a comfortable lying position in the experimental group and control group. The deep cervical flexor muscle thickness was measured in the longus colli and longus capitus using ultrasonography. The muscle tonicity and muscle fatigue of the superficial cervical flexor muscle were measured separately in the sternocleidomastoid muscle using a myotonometer and electromyography. RESULTS: In the experimental group(functional latex pillow), the muscle tonicity of the superficial cervical flexor muscle like the sternocleidomastoid muscle was significantly lower than that of the control group (general pillow)(p < .01). CONCLUSION: This study suggests that the functional latex pillow may effectively reduce the muscle tonicity of the sternocleidomastoid muscle, which is the superficial cervical muscle, in patients with chronic cervical pain. On the other hand, it was not effective on the muscle thickness of the deep cervical flexor muscle and muscle fatigue of the superficial cervical flexor muscles.

For the purpose of decreasing the chair time in implant cases, the time needed to loosening and fastening the screw must be shortened. Nowadays, the two typical designs of screw head are slot and hexa form. This study aimed at the shortening of loosening and fastening time by modifying the slot and hexa form. Total of twelve dentists participate in these experiments, four of them were experienced and eight of them were novice dentists. 1. There were many differences in the speeds of screw loosening and fastening between personal experiences. Experienced dentists are faster than novice dentists. 2. There were many differences in the speeds by angulation of the implant, by the conditions of the muscle tonicity. 3. Revised slot and hexa Heads show the slightly shortened time for acrew looseing and fastening.

The toxicity of muscle in pufferfish, Tikifugu vermicularis radiatus is known to be weak. However, no food poisoning has reported in this species although market consumption has been relatively high in Korea, especially on western coastal area. It presumes that there could be different toxicity in fish muscle of fresh and frozen specimens. In this regard, the frequency of toxic fish, the toxicity level in fresh and frozen fish as well as highest toxicity ann average toxicity were investigated. From the results, weak toxicity was detected in frozen fish muscle whereas no toxicity was measured in fresh fish. According to this, it is suggested that the toxicity of frozen and fresh fish must be tested simultaneously when tonicity of pufferfish is investigated. The above results implicate that toxicity of pufferfish may be due to the phsyical treatment such as freezing or thawing process.

This paper relates the occidental constitutional theory to the oriental one, concluding their origins to be similar, and demonstrates a new method of constitutional diagnosis by O-Ring Measurement System Of Muscular Meridians and Laser Constitutional Diagnosis. It establishes Laser Constitutional Diagnosis(L.C.D) using laser beams according to the principles of acupuncture and Sa-Sang constitutional physiology under the effect of spatial morphological energy of geometric isomers. Finally, hypothetical theory of L.C.D. was experimented by the O-Ring Measurement Systems of Muscular Meridians(O-R MSMM). O-R MSMM has been specially devised to improve the manual O-Ring Test prevailing to distinguish energetic response by muscle tonicity. Statistically, it has been proved that the constitutional diagnosis with O-R MSMM was highly effective and objective in the clinical experiences.
