Όλ¬Έ (μμ¬)-- μμΈλνκ΅ λνμ : μλ¬Όμμ°κ³ΌνλΆ(μμκ³Όνμ 곡), 2012. 2. μ΄μΉκ΅¬.This study was conducted to elucidate effects of forced heated air vent on sprouting and chlorine dioxide (CD) gas on qualities of field cured onion Turbo bulbs. Forced heated air vent was conducted at 30oC for 8 days or 40oC for 4 days under the 60% relative humidity (RH), and then onion bulbs were stored at 5oC for 6 months. Skin moisture contents, weight loss, malondialdehyde (MDA), respiration rate, and sprouting were measured. CD gas was applicated on unpeeled and peeled onion bulbs, and onion skins inoculated with microorganism at the concentration of 1000, 500, or 250 ppmv for 1, 0.5, or 0.25 hour, then samples were stored at 0oC for 7 weeks. Visual appearance, weight loss, total soluble solids (TSS), pungency, firmness, total phenolic content, and reduction of the number of microorganisms were measured. Forced heated air vent treatment reduced the moisture contents of onion skins without any influence on the sprouting of onion bulbs. And application of CD gas on onion bulbs with intact skins reduced the number of microorganisms on onion surfaces without any deterioration in qualities of onion bulbs. Therefore, forced heated air vent is a postharvest process useful in the storage of onion bulbs and CD gas is a disinfectant applicable on onion bulbs for the storability.λ

[μλ¬Έ]This study was designed to develop the Korean Activities of Daily Living (ADL) evaluation tools for persons with stroke applying the Rasch model based on item response theory. The total subjects for this study were 477 stroke patients, 308 inpatients and 169 outpatients, at 18 different rehabilitation facilities in Korea. Questionnaires containing ADL evaluation items selected in advance with the Q-sorting method from the preexisting ADL related literatures were distributed to the subjects by mail or visit. Rasch analysis was then done by means of the Winsteps program to determine the validity and reliability of the Korean ADL evaluation tools for persons with stroke. The results were as follows :1. In case of inpatients, three items were found to be misfits and the order of item difficulty of the remaining 20 items was arranged. Stroke inpatients'' ADL ability is indicated by -6.77~6.73 logit, and the transformation formula is βscore=(logit score+6.77)/(6.77+6.73)Γ100.β2. In case of outpatients, seven items were found to be misfits and the order of item difficulty of the remaining 16 items was arranged. Stroke outpatients'' ADL ability is indicated by -6.32~6.23 logit, and the transformation formula is βscore=(logit score+6.32)/(6.32+6.23)Γ100.β3. In the order of difficulty of evaluation items, inpatients and outpatients responded equally. The most difficult item was βgoing up and down stairs,β which was one from the functional mobility domain. And the easiest item was βdrinking,β which was one from the feeding domain.In conclusion, the Korean ADL evaluation tools for persons with stroke have been proven reliable and valid. Therefore they are expected to be used as effective tools for treatment planning and intervention for persons with stroke.ope

The purpose of this study is to examine the differences between the degree of depression experienced by stroke patients and that of his/her caregivers. During the period from March 13 through April 13, 1995, 116 patients and caregivers were each presented with a questionnaire to determine the differences between the
patient's severity of depression and the degree of depression experienced by the caregivers as a result of their respective depression characteristics. Furthermore, in order to determine the states of depression and nondepression, characteristics
of depression were quantified by using a point system to classify the patients and their caregivers into two groups.
The results are as followed:
1. Amongst the 116 stroke patients surveyed, 43 patients (37%) fell under the category defined as depression, 38 patients (33%) were defined as mild to moderate depression and 5 patients (4%) as having moderate to severe depression. However, no patient fell under the category of severe depression.
2. Factors linking the psychological state of mind and the severity of depression were the patient's level of education, type of treatment, degree of home program training, adaptability to treatment, drug intake, and functional status.
3. The levels of depression recorded by the caregivers were much lower than those recorded by the patients. This was a result of the caregiver underestimating the patient's severity of depression.
4. The level of depression experienced by the patient's son(S),daughter(S), daughter-in-law(S) were higher than that recorded by the patient's spouse.
5. The variables affecting the caregiver's recorded degree of depression were the following: care period, living with the patient, knowledge about stroke care, and the caregiver's health status.
6. Based on the characteristics categorizing the nondepressed and depressed group, the patients were most affected by the area of paralysis, pocket money and the taking of diabetic drugs. On the other hand, the caregivers were most affected by marriage status and the period of care.
7. The highest points were given to the psychological disturbances of depression for the patients and physiological disturbances of depression for the caregivers.
As a result of this study, it may be concluded and recommended that stroke patients should, in addition to physical rehabilitation, be exposed to neuro-psychological treatment not only for minimizing the after-affects of stroke but also to maximize support from the caregiver and family. Thus, it is recommended that, for full and successful recovery of a stroke patient, a psychologist must be present to act as a mediator for the patient and their respective family members.restrictio
