Four females and a male nematode isolated from 2 patients who visited eye clinics In Seoul were identified as Thelazia callipaeda and their ultrastructures were observed by scanning electron microscopy(SEM). General features of the worms were slender and attenuated at both ends. Vaginal opening was located at 0.27 mm from the anterior end, and in front of the esophagointestinal junction. In the body cuticle transverse striations varied characteristically through the body. The number of cuticular transverse striations was 400∼650/mm at head portion, 250/mm at middle portion and 300∼350/mm at tail portion. The SEM observation of the mouth part of the females showed 6 cord-like cuticular thickenings in hexagonal arrangement and an amphid was observed. A lateral line, a vaginal opening, a pair of phasmids, and an anus were identified in the body portion. A pair of papillae and 6 cord-like cuticular thickenings were on the mouth part of the male. It was difficult to observe structures at the tail of the male except wrinkle-like structures. Most of the larvae isolated from the uterus of a female worm were sheathed and thus cuticular striations were not Eren. Others were unsheathed and revealed cuticular striations. The oval membrane which encysted sheathed larvae was also observed. These are the 18th and 19th record of human thelaziasis in Korea as the literature are concerned.

During a study to document more fully the parasitic ciliates of Korean freshwater fishes, we found numerous small ciliates in the gills and skin of crucian carp, Carassius carassius. Cursory examination indicated that the ciliate were very similar with Chilodonella sp. In this study, we described the morphometrics of this ciliate in detail and compared with other species of Chilodonella in the world. Numerous small ciliates were observed in the body surface, fins and gills of infected fish and excessive mucus production were seen in those fish. Sometimes ulcer was observed in the body of moribund fish. From the scrutinized observation of the parasite, it was identified as Chilodonella hexasticha. The parasite was dorsoventrally flattened body, without a notch in the posterior margin, and it measured 30-$45{\mu}m$ long and 15-$30{\mu}m$ wide. In number of kineties, the right band ciliature was 3-5 and the left band ciliature was 3-5. The right ventral ciliary band shaped arch and was longer than the left, straight band. It had a single oval macronucleus, 8-$15{\mu}m$ in diameter, a single micronucleus, 2-$4{\mu}m$ in diameter. The cytopharynx was reinforced by 10-16 conspicuous nematodesmata, which shaped like a tube and curved at its inner end. Two contractile vacuoles, one anteriorly at right and the second posteriorly at left were observed in wet mounts. This parasite reproduced by a simple division at $22{\pm}1^{\circ}C$.

This thesis aims to reveal the unsatisfactory unfitting factors in the tight collars of adult males' dress shirts for the purpose of improving neck-collar fitness. For this study, nine adult males were chosen as the subjects. When the subjects erected their necks upright, the researcher conducted an experiment, using the direct anthropometrical measuring method and the gypsum method by turns, in order to understand neck shapes by way of right-neck lateral flection, left-neck lateral flection, neck flection, neck extension, right neck rotation, and left neck rotation. And then, the propriety of allowances from body surface alteration was verified by analyses through the measurement of wearing comfortableness and clothing pressure in two sorts of ready-made dress shirts, which had different allowances. The consequences of this study are as follows: 1. In length alteration to movement, a decrease was found in the opposite (and an increase in the identical) directions of right-neck lateral flection, left-neck lateral flection, and neck flection movements. Also, when the subjects shook their heads, an increase was seen by 0.42$\sim$0.63cm in neck girth, 0.31$\sim$1.12cm in 3cm-above-the-neck base girth, and 1.16cm in neck extension of 3cm-above-the-neck base girth. 2. As a result of the drafts of surface measurement, the alteration ratios of dimensions and vertical length dropped in the identical directions of the movement, but grew in the opposite directions. A reverse change was shown in horizontal length. The rough widening gaps for making drafts were 0.7cm in front left and right, and 0.2cm in back left and right of 3cm-above-the-neck base girth. On the whole, the space was about 1.8cm, while there was no significant variation between the upright stationary test and the movement test. 3. There were important differences between the two kinds of ready-made dress shirts (Type A: 1cm allowance in neck girth; Type B: 2cm allowance) in clothing pressure and wearing comfortableness. That is, Type A had higher pressure and more uncomfortable sense of wearing. In other words, as clothing pressure and wearing comfortableness are negatively related to each other, Type A's greater clothing pressure led to worse wearing comfortableness.

The purpose of this study was to assess the intra-rater, inter-rater and test-retest reliability and validity of frontal plane lower extremity alignment estimated from a rasterstereographic method using ABW-Mapper. Eighteen subjects participated in this study. The S angle (stereographic angle-frontal plane lower extremity alignment estimated from a rasterstereographic method) in standing was measured throughout the two sessions with one week interval by two different readers. In the first session, a reader measured S angle twice per subject with a short break in-between. The Q-angle (quadriceps angle) was measured using a standard goniometer from a photography taken through digital camera with the participant standing in the same position as in the S angle measurement. The HKA(hip-knee-ankle) angle was measured from a computer based digital radiograph with the computerized measurement software. Reliability was tested using intraclass correlation coefficients(ICC). Validity was tested using a Pearson's correlation coefficient. Excellent intra-rater(ICC=0.956~0.974), inter-rater(ICC=0.962), test-retest reliability (ICC=0.945) were demonstrated. There were strong negative correlations between S angle and Q-angle (r=-0.739), and between S angle and HKA angle (r=-0.702). Therefore, the S angle measured using a rasterstereographic mapper may be used to as a preliminary or supplementary tool to evaluate and study LE alignment in the frontal plane in relation to HKA angle or Q-angle.

This study was carried out to determine the influencing of electrical stimulation to cervicothoracic sympathetic ganglion(CTSG; stellate ganglion) u the sympathetic tone. For the purpose of this study. the stimulation was given to both the interferential current stimulation(ICS: AMF 100Hz) group consisting of 10 person(males 8, females 2) and the transcutaneous nerve electrical stimulation(TENS: 100 Hz) group of 10(males 7, females 3) in the right side of the trachea with probe electrodes. Then. the temperature changes on the surfaces of the forehead. cheek, neck and internal ear of cephalocervix, which is subject to the influence of the cervicothoracic sympathetic ganglion, and the palm. which is the end of the upper limbs. measured before. immediately alter. 10 minutes after and 20 minutes after experiment. The results are summarized as follows. 1. The emergence of remarkable Horner's symptoms which appear due to the changes of the tone of cervicothoracic sympathetic ganglion was not seen. However, in the interferential current stimulation group there were two felt the sense of warmth in the facial region and one person who felt it in the upper limbs, and in the transcutaneous nerve electrical stimulation group there was each one person who felt the sense of warmth in the facial region and in the upper limbs, respectively. Both groups have each one person who felt the sense of oppression in the eyelids. Three persons of the interferential current stimulation group and two persons of the transcutaneous nerve electrical stimulation group have the sense of hoarse voice or numbness in the neck. These are the symptoms that appeared during stimulation, so it is difficult for them to be considered as the direct effects of the changes of the tone of cervicothoracic sympathetic ganglion. 2. The t-test was performed to determine the significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significant changes were seen in the necks of the interferential current stimulation group and in the cheeks and internal ears of the transcutaneous nerve electrical stimulation immediately after experiment(P<.05). And the interferential current stimulation group showed a very high significance in the cheeks immediately after experiment and in the necks ten minutes after experiment(p<.01). Therefore, it could be seen that the electrical stimulation had an influencing on the changes of body temperature of the cephalocervix. 3. In both the interferential current stimulation group and the transcutaneous nerve electrical stimulation group, the forecheads, checks and necks of the cephalocervix in the experimental side(right) rather than the non-experimental side(left) had mostly a statistically significant rise in temperature immediately after experiment. The one-way ANOVA was carried out to determine the temperature change of on the surface of the body with the lapse of time; before, immediately after, ten minutes after and tewenty minutes after experiment. But no statistical significance was found from both the right and left sides.

The ultrastructure of the integumental epidermis of Korean planaria (Dugesia japonica) is studied by light microscope, scanning electron microscope and transmission electron microscope. The planaria has mono-layered integumental epidermis in which most of cells exhibit irregularly columnar shape. The epidermal cells of the integument are classified into six types on the basis of cytochemical and ultrastructural characteristics. 1) Ciliated epithelial cells: These cells have cilia in their free surfaces. The axonemes of cilia exhibits fundamental 9+2 microtubular pattern. 2) Eosinophilic cells: These cells contain a few large eosinophilic granules. The core of eosinophilic granule is consisted of sparsely dispersed fibrillar structures in relatively electron-lucent ground material. 3) Mucous cells: These cells are filled with irregularly shaped, PAS-positive mucous granules which have an average size of $0.8\\times0.3 \\muM$. 4) Rhabdite-forming cells: These cells possess a few strongly-eosinophilic large rhabdite granules. The rhabdite granules are synthesized either in the rhabdite-forming cells which constitute integumental epidermis or in the corresponding cells which are developed in the parenchyma and later transferred to epidermal cells of integumental epidermis through basement membrane. 5) A-type of basophilic granule cells: These granule cells possess round or irregularly-shaped granules which are strongly stained with Alcian blue. These electron-dense granules have an average size of $1.5\\times1.0 \\muM$. This type of cells is derived from parenchymal tissue. 6) B-type of basophilic granule cells: These basophilic granule cells with PAS-positive granules, are found in the epidermis of lateral body wall. The granules, which are about $0.7\\times0.4 \\muM$ in size, occupying most part of this cell type are originated from the parenchyma.

Exposure measurement of agricultural worker to pesticide is one of important part of health risk assessment of pesticide. Therefore exposure matrices, apparatus, instruments and methods must be validated in advance to field experiment. In this study, method validation with an organophosphorus insecticide fenthion was carried out for exposure monitoring of agricultural worker. LOD and LOQ were 0.01 and 0.05 ng, respectively. Calibration curve linearity ($R^2$ > 0.999) and reproducibility (C.V. < 3%) were also excellent. Recovery at LOQ, 10LOQ and 100LOQ levels from gloves, socks, mask, patch, solid sorbent, glass fiber filter was 76~113% (C.V. < 3%). Trapping efficiency was 95~105% while no breakthrough was observed. Method validation for the exposure monitoring was established successfully through several experiments. Such method validation can be usually performed in laboratory and not much different for each pesticide so that, this techniques will be applied widely in research for pesticide exposure monitoring by combination with body surface area and respiration rates.

Total body irradiation (TBI) requires large radiation field and extended source to axis distance (SAD), therefore in needs large size treatment room and it needs compensators which components. Appropriate thickness beam spoiler should be used to raise skin dose. Treatment machine, photon energy, total dose, dose rate, dose fractionation, patient position, shield of normal tissues and organs were known to important parameters for TBI. TBI disturbes regular daily treatment schedule and significantly overloads Radiation on oncology departments and during the treatment session it requires accurate reproduction of radiation field and patient position. We were enable to TBI in small size treatment room and short SAD with parallel opposing lateral fields technique and achieved homogenious whole body dose distribution using pb compensators and controled lung dose by lung shield blocks. Drawing a patient shadow on the wall, we could shortened set up time and possible to accurate reproduction of radiation field and patient position.

Objectives : The purpose of this study was to compare the skin temperature changes by the rechargeable and programmable electronic moxibustion device(EMD) with the traditional combustible moxibustion device(CMD). Methods : Skin temperature changes in six healthy volunteers induced by CMD and EMD were measured with digital infrared thermal imaging(DITI). Heat stimulation was applied on $LI_4$ and $TE_5$, and skin temperature changes on each point were measured at baseline and per minute for total 7 minutes, 2 minutes of heat stimulation and 5 minutes of observation. Results : There was no significant difference in the skin temperature changes between CMD and EMD. The temperature on $LI_4$ with EMD was $32.3{\pm}1.3^{\circ}C$ at baseline, $34.0{\pm}1.3^{\circ}C$ at 1 minute after heat stimulation start, $34.6{\pm}1.2^{\circ}C$ at 2 minutes after, and from 3 minutes after heat stimulation, it maintained $32.6{\sim}32.8^{\circ}C$. Conclusions : Methods for measuring skin temperature changes induced by heat stimulation of moxibustion were established, and the possibility of effectiveness of the newly developed electronic moxibustion device was raised with this preliminary study. This study can contribute to the development of clinical research methodology for traditional Korean medicine.
