  • The chemical fractions of phosphorus were investigated in the soils of reclaimed and natural tidelands of southwest coastal area of Korea. The content of total-P varied to ranged from 322 to 614 mg/kg dry weight with a mean value of 467 mg/kg. The order of different fractions of phosphorus in reclaimed tideland soils was as follows: 1) inorganic phosphorus: Ca-P > Fe-P > Al-P > reductant soluble Fe-P. 2) organic phosphorus: Inositol-P > nucleic acid-P > phospholipid-P. The content of Al-P showed negative correlation with organic matter content but showed positive correlation with pH. The content of Fe-P showed negative correlation with clay mineral content but showed positive correlation with organic matter content. Reductant soluble Fe-P and Ca-P were no correlation with soil properties. The content of inositol-P showed highly positive correlation with clay mineral, organic matter content, and CEC.

  • PURPOSE: This study was conducted to investigate the correlation between the activity of suprahyoid muscles, infrahyoid muscles and swallowing ability in stroke patients with dysphagia. METHODS: The subjects of this study were 120 patients who were diagnosed with CT or MRI stroke and had swallowing disorder at Daegu Metropolitan General Hospital from August 2014 to February 2017. The suprahyoid and infrahyoid muscle activity was measured in patients with dysphagia and the new videofluoroscopy swallowing studies scale (new VFSS scale) was used for evaluation of swallowing function. Correlation analysis was conducted using the measured data. RESULTS: The activities of suprahyoid muscles were 325.8 (%RVC) on average, while the average infrahyoid muscle activity was 302.65 (%RVC) and the average value of the new VFSS scale was 31.52. The total for oral organs was 3.62 on average and that for pharynx organs was 28.30 on average. The activity of the suprahyoid muscles showed a significant positive correlation with the activity of the infrahyoid muscles, but a significant negative correlation with the total oral phase, total pharyngeal phase and total new VFSS scale (p<.01). The activity of the infrahyoid muscles showed a significant negative correlation with the total oral phase, total pharyngeal phase, and total new VFSS (p<.01). CONCLUSION: Based on the results of this study, it is necessary for researchers to consider the infrahyoid and suprahyoid muscles when conducting swallowing rehabilitation.

  • This study was designed to identify how the incidence and severity of premenstrual. syndrome (PMS) correlate with the nutrient intakes and exercise habit of women. The subjects of this study were 299 women residing in Busan metropolitan city. Each subject was asked to complete a menstrual discomfort questionnaire (MDQ) for PMS and nutrient intakes. PMS symptom scores of women in their twenties ranked in order of severity were: behavioral change (2.45), followed by pain (2.36) and water retention (2.28), negative effects (2.20), autonomic reaction (1.91), arousal (1.87), decreased concentration (1.76) and decreased control (1.74). For Women in their thirties, the symptom of pain was the most dominant (2.93) followed by autonomic reaction (2.69) and behavioral change (2.54), and for those in their forties, negative effect (3.06) was highest, followed by pain (2.97) and autonomic reaction (2.86). The overall symptoms of PMS significantly increased with age (20': 2.07 points, 30': 2.34 points, 40': 2.47 points). There was no correlation of the BMI of the subjects with the symptoms of PMS, but there was a significant negative correlation between the symptoms of PMS and exercise frequency for women in their thirties and forties. Subjects in their twenties exhibited a significant negative correlation for PMS symptoms with the intake of carbohydrate (p < 0.05), calcium (p < 0.05) and vitamin E (p < 0.05). For subjects in their thirties, PMS symptoms were negatively correlated with the intake of calcium (p < 0.05) and vitamin C (p < 0.05); and in women in their forties, calcium (p < 0.01) and carbohydrate (p < 0.05) intakes were negatively correlated with PMS symptoms. This suggests that PMS represents the clinical manifestation of a nutrient deficiency state, especially calcium. Therefore, we concluded that nutrient supplementation and exercise management are likely to be of benefit in relieving PMS symptoms.

  • The study analyzed the effects of topographic structures and altitude in mountainous parks in Mt. Namsan in Gyeongju on the generation of anions. The temperature was at ridge ($9.82^{\circ}C$) > valley ($8.44^{\circ}C$), the relative humidity valley (59.01 %) > ridge (58.64 %), the solar radiation ridge ($34.40W/m^2$) > valley($14.69W/m^2$), the wind speed ridge (0.63m/s) > valley(0.37m/s), and the negative ion valley($636.81ea/cm^3$) > ridge($580.04ea/cm^3$). In the valley, the correlation with altitude was verified for the temperature, relative humidity, solar radiation, and negative ion generation in the valley. The relative humidity, solar radiation, and negative ion indicated a positive correlation while the temperature had a negative correlation. In the ridge, the correlation with altitude was verified for the temperature, relative humidity, wind speed, solar radiation, and negative ion generation. The relative humidity, solar radiation, and negative ion generation indicated a positive correlation while the temperature and wind speed had a negative correlation. The regression analysis showed the prediction equation of y=-0.006x+9.663 (x=altitude, y=temperature) in the valley and y=-0.009x+11.595 (x=altitude, y=temperature) in the ridge for the temperature, y=0.027x+53.561 (x=altitude, y=relative humidity) in the valley and y=0.008x+56.646 (x=altitude, y=relative humidity) in the ridges for the relative humidity, and y=0.027x+53.561 (x=altitude, y=negative Ion generation) in the valley and y= 0.008x+56.646 (x=altitude, y=negative Ion generation) in the ridge for the negative ion generation.
