We investigated environmental conditions in plastic houses and collected basic physiological data which might help to prevent what is called “plastic house syndrome.” The results of the study is summarized as follows
1. The internal environment is closely related to the changes in external temperarure as well as the size, type, direction of house, and growing crops. Also, physiological responses were defferent according to the conditions of the internal environment and hardness of work. The current investigation confirmed that working conditions in single-type small plastic houses were worse than in multiple-type houses with same crops.
2. A major facter of physiological stress for the greenhouse workers was the sudden change in temperature (16-23°C) between the inside and outside of the plastic house during the winter season.
3. Since the temperature within the single-type small plastic house rises up to 50° during spring months, workers experienced more severe thermal load and mental stress from prolonged work.
4. It was suggested that an improved type with a resting room might help to reduce the physiological stress and buffer the sudden change of working enviroment. Thus, it is recommended to provide a resting room whose temperarure is intermediate between external and internal temperatures, so that workers might be able to adjust themselves to the environment when they follow the safety procedures.
5. It is safe to conclude that the temperature in the resting area should be kept half way between outdoor and room temperatures, even though there must be some variation with the type of house and crops. According to the current investigation, therefore, a resting area should keep the temperature between 13-16°C 28-31°C during winter and spring, respectively.

We investigated the cold reaction of fingers in cold water as a criterion of peripheral resistance to frostbite in order to obtain elementary data to improve farmers' health. Experiments were carried out on 81 farmers and 64 urbanites at 20±2°C, 55±5% RH with sitting position on the floor. The finger skin temperatures of the subjects were measured while the left middle finger of each subject was immersed in cold water or 0°C for 30 minutes and recorded once every one minute with the thermistor. We also compiled statistics on the following items: mean finger skin temperature (MST), finger skin temperature at initial rising after immersion (TFR), time for the appearance of initial rising after immersion (TTR), cold resistance index (RI), etc. The results were as follows RI was higher in farmers than in urbanites, but there was no significant difference between the two groups. In men, RI was lower in farmers than in urbanites, but there was no significant difference between the two groups. By contrast, in women, TFR and RI were significantly higher in farmers than in urbanites. MST was significantly higer in women than in men, but RI was no statistically significant difference. By age, the men in their 30's showed significantly the highest MST and the shortest TFR. RI was significantly higher in the men in their 30's than others. In women, however, the difference in RI was of no statistical significance. By region, MST was the highest in Seoul dwellers. RI was the highest in Okku dwellers, but there was no statistically significant difference among regions.
These results indicated that farmers tended to be higher than urbanites in cold resistance index.

To collect the basic data for the health management of Korean farmers, we investigated physique factors, physical fitness, and cold resistance (by digital vascular hunting reaction during finger immersion in cold water), and examined their correlations in 74 subjects. In men, the stronger the digital vascular hunting reaction was the higher the physical fitness levels. For women, however, the motility of those who showed stronger digital vascular hunting reactions appeared worse. The correlation between physique and hunting reaction appeared weak in men but in women the hunting reaction of obese subjects was stronger than that of slender subjects. Agewise, men in their 30s, 40s and 50s who were short and slim appeared to have better cold-resistance. The men in their 60s who were broad-hipped had better cold-resistance, and the relation between physical fitness and hunting reaction appeared to be negative. In contrast, the women in their 30s whose subcutaneous fat was thinner showed positive hunting reaction, but in their 40s and 50s the correlation among physique, physical fitness, and hunting reaction appeared rather weak. The body fat content in the women aged 60 to 69 was high compared to that in other age groups. Among them, those who had less fat and better physical fitness showed more favorable hunting reactions.

It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

PURPOSE: The purpose of this study was to identify the effect of Meridian pressure on the functions of upper extremities and discomfort of ADLs of hemiplegic patients. METHODS: The research design was a nonequivalent control group, non-synchronized design. Subjects were 35 hemiplegic patients who were hospitalized at L Oriental Medical Hospital; 18 for the experimental group and 17 for the control group. The experimental group was given meridian pressure for 10 minutes daily for 2 weeks. The data were analyzed by SPSS 12.0 program. The chi-square-test and t-test were used for the two groups' homogeneity, and t-test was used for the hypothesis test. RESULTS: Manual muscle test, ROMs of wrist extension, elbow flexion, and shoulder extension of the experimental group increased compared to the control group. Shoulder pain and index finger circumference of the experimental group decreased compared to the control group. The experimental group showed to have less discomfort of ADLs than the control group. CONCLUSION: The study results verified that meridian pressure is effective for improving the functions of hemiplegic patients' upper extremities as well as reducing discomfort of ADLs.

Kimura's disease is a benign, uncommon, chronic inflammatory condition that usually presents with painless subcutaneous nodules or plaques. Head and neck are the most frequently involved sites in Kimura's disease. Mandible is the most commonly involved, followed by neck, cheek, scalp and forehead. Other possible sites are oral cavity, inguinal area and extremities, but there have been no reports involving the nose, especially the one that looks like a rhinophyma. We describe a case of Kimura's disease presenting like a rhinophyma.

We investigated a unilocular mammary cyst occurring in a two and a half year old male baby. The cyst was lined by simple columnar epithelium and filled with a milky secretory material. These histologic features were consistent with galactocele. The child had enlarged left breast since birth, but it seemed to be noncontributory as the child had neither endocrine abnormalities nor perinatal disorders. Galactocele is an uncommon breast lesion usually occuring in females following lactation. It is rarely a cause of breast enlargement.

We have recently managed three cases of cerebellar hemangioblastomas in adult male in which the vertebral angiograms and C-T scan led us to diagnose the vascular mass lesions involving the right, left lobe and superior vermis respectively. Polycythemia, angiomatosis retinae and familial incidence were not detected but signs of increased intracranial pressure and of cerebellar dysfunction in varying degrees were common to all three cases. The duration of symptoms and signs ranged from weeks to years. The lesion in the right lobe was a fairly large mass harboring multiple small cysts in it and able to removed completely. The mass in the left lobe was paramedian in location and obstructing the 4 th ventricle. It was also large and entirely cystic accompanying a mural nodule in it and easily removed completely. The lesion occupying the cerebellar vermis was a large solid one and extending diffusely up to posterior third ventricle region and could only be removed partially.
