Objectives: The main purpose of this study was to investigate the possible differences in sleepiness, performance, and body temperature during the night between morning(M) and evening(E) type subjects. Methods: After a survey study, to verify the validity and reliability of the Korean translation of the Home' and $\ddot{O}stberg's$ Morningness-Eveningness Questionnaire(1976), 8 extreme M-type subjects(3males, 5 females) and 8 extreme E-type subjects(3 males, 5 females) were selected from the university student population who had participated in the survey study. All subjects underwent sleep latency test and a battery of performance tests at intervals of 2 hours through the night, from 23:00 to 07:00. Oral temperature of each subject was taken every hour from 21 : 00 to 8 : 00. Between the testing times, the experimenters ensured that subjects remained awake. Results: More profound sleepiness was found in the M-type compared to the E-type throughout the night, with significant differences in sleepiness occuring at 23:00 and 01:00 hours. Overall performance efficiency tended to be lower through, the night in the M-type than in the E-type on all tests. A difference in time of temperature minimum between the two types was not noteworthy. Rather, there appeared to be a substantial difference in temperature level during the declining phase, with the temperature of the M-type being lower than that of the E-type. Conclusions: These results indicate the existance of a temporal relationship between sleepiness, perfonnance and body temperature during night work. Since the M-type exhibited greater sleepiness and lower performance efficiency overnight than the E-type, it may be assumed that the E-type is more suitable for and tolerable to night work. There was some discussion of the limitations in generalizing these results together with some suggestions for future studies.

Nasal valve compromise (NVC) is a distinct cause of symptomatic nasal obstruction, yet there are several ambiguities surrounding the diagnosis and management of this disease. Understanding of nasal valve anatomy with critical assessment of the site of obstruction is essential to effective nasal valve management. Technique selection should be individualized to the type of valve dysfunction. This case report presents a 56 year old man with nasal valve dysfunction due to narrow middle vault, concave lower lateral cartilage and swollen septal body which was diagnosed by various techniques including navigation system and treated by spreader graft, alar batten graft and reduction of septal body.

This study was performed to figure out effects of stroke rehabilitation on education using isokinetic exercise on physical function recovery. It is considered isokinetic exercise will playa primary role in muscle strength, ROM of joint, and body balance recovery for stroke rehabilitation and so far can be used as a basic references to increase the health of all people. The study consisted of 42 stroke patient(21 training group, 21 control group) diagnosed as cerebral hemorrhage from Oriental Rehabilitation Department of Kyung Hee University. Upper extremity and lower extremity exercise was performed in the training group using isokinetic ergometer. The recovery of physical function(muscle strength, ROM of joint, body balance) data between the two groups were compared and ana lysed by paired t-test are as followed. 1. Muscle testing record showed increased in the strength of elbow flexion, knee flexion, knee extension, ankle extension of the training group com paired to control group(p < .05). In the measurement of ROM, however other parts of the body motion showed no significant changes, only shoulder extension of the training group was increased(p < .05). 2. Body balance increase was highly significant in all training group compaired to control group(p<001). Based on these findings, stroke rehabilitation education with isokinetic ergometer showed available effects on recovery of physical function rehabilitation program with isokinetic exercise will play a primary role in the recovery of physical function of stroke or brain injury patients as well as to promote the health of all people.

This study identified the differences in the morphometric characteristics of the truss and classical dimensions between diploid and triploid Far Eastern catfish, Silurus asotus, and provided methods for sorting diploid and triploid Far Eastern catfish based on morphometric observations. The significant variables were the direct distance between the anterior edge of the lower lip and the anterior insertion of the dorsal fin(DALAD), the horizontal distance between the anterior edge of the lower lip and the anterior insertion of the ventral fin (HALAV), the direct distance between the anterior edge of the upper lip and the first nostril(DAUF), the direct distance between the anterior edge of the upper lip and the second nostril(DAUS), the interorbital width(IW), and the mandible barbel length (ManBL). The more significant variables were HALAV, DALAD, DAUF, IW, and DAUS. The most useful combination of variables for separating the two groups was DALAD, IW, and DAUF, which correctly classified 85% of the catfish as triploid or diploid, and that percentage was the maximum degree of value possible (p<0.05). Triploid Far Eastern catfish had a high rate of growth in the head region and body depth during the first year after hatching. Triploid Far Eastern catfish had smaller heads and shorter mandible barbels than diploid Far Eastern catfish.

There is hardly any helpful data from the studies on the clothing pressure of men, because most studies about the clothing pressure have been attempted to analyze the case of women. This study, therefore, was done about the men's waist which was most highly pressured of the body. RESULTS: 1. The pressure from the waist when the man puts on summer wears was as follow ; the case when standing, the pressure from the abdomen was 28.99±14.37g/㎠, and the one from the side 34.14±14.79g/㎠, the case when sitting on the chair, the pressure from the abdomen was 31.27±15.59g/㎠, and the one from the side was 33.39±13.23g/㎠. 2. The pressure from the abdomen was increased in proportion to the Rohrer index. 3. The clothing pressure given the waist was lower in case of the men with digestive disorder than the ordinary ones.

An atlantoaxial subluxation from the unstable Os odontoideum by the failure of proper integrations between the embryological somites might be a commonly reported pathology. However, its suspicious origin or paralleled occurrence with other congenital anomalies of vertebral body might be a relatively rare phenomenon. The authors present two cases, who simply presented with clinical signs of prolonged, intractable cervicalgia without any neurological deficits, revealed this rare feature of C1-2 subluxation from the unstable, orthotropic type of Os odontoideum that coincide with congenitally fused cervical vertebral bodies between C2-3. Surprisingly, in one case, when traced from the lower cervical down to the thoracic-lumbar levels during the preoperative work-up process, was also compromised with multi-level butterfly vertebrae formations. Presented cases highlight the association of various congenital vertebrae anomalies and the rationale to fuse only affected joints.

Natto, one of Japanese traditional food is made from steamed whole soybeans fermented with Bacillus natto. In this study, the effects of Natto mucilage- feeding on griwth, organ weight and serum nitrogen compounds of rats were investigated. Male rats in Sprague-Dawley strain were fed on basal diets supplemented with aqueous Natto mucilage of several percentages for 10 weeks. Natto mucilage had no significant effects on the body and organ weights. The levels of GOT, GPT, LDH. and total bilirubin in serum of rats fed Natto mucilage diets were significantly lower than those in the control group ' The levels of total protein and albumin were higher than those in the control group. The level of calcium in serum indicates a growing tendency. but creatinine, uric acid, and BUN had declining. And the most component of free am1no acids in Natto mucilage were glutamin acid.

A 68-year-old man presented with a bed sore with pus discharge on lower back. Radiographs showed extensive destruction of the L4 vertebral body. Magnetic resonance imaging (MRI) showed fluid collection with an enhanced wall at the defect of the L4 vertebral body extending into both psoas muscles. The primary diagnosis was neuropathic spondylopathy, but infective spondylitis was not ruled out. Initially, he was treated with antibiotics for two weeks. A follow-up MRI showed no improvement of the abscess, so surgical exploration was done. Charcot spinal arthropathy resulted in extensive vertebral body destruction that may be similar to infectious spondylitis, particularly in the case with fluid accumulation due to rupture of dura.

This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.

Liposarcoma is one of the most common malignancies originating from human soft tissue. Because most of liposarcoma occur in the lower extremities or retroperitoneum, there are few reports about liposarcoma of head and neck region, including larynx and pharynx. Histologically, there are four types of liposarcoma, and prognosis and recurrence rate are different according to histologic subtype. Wide excision is the treatment of choice and liposarcoma hardly respond to primary radiotherapy. A 56-year-old man presented with voice change and foreign body sensation in laryngopharynx. Hypopharyngeal liposarcoma was diagnosed by surgical biopsy and performed totallaryngopharyngoesophagectomy and gastric pull-up. Here we report our experience on this case with review of literature.
