Purpose: This study aims to find the factors that affect the degree of self-care performance in Parkinson's disease (PD) patients. Method: This study used a descriptive correlational design. The data were collected using a sample of 80 PD patients, from the university affiliated Parkinson Center in Busan. Pearson's correlations and multiple regression analyses were conducted using the SPSS 18.0. Results: The mean score of the self-care performance was 3.61 (${\pm}0.40$). The highest score observed of self-care performance subscale was medication subscale ($4.55{\pm}0.50$) and the lowest score was observed in the exercise subscale ($3.03{\pm}0.64$). The self-care performance had significant correlations with depression (r=-.32, p<.01), self-care knowledge (r=.28, p<.05), function of motion (r=.25, p<.05), ability of daily activity (r=.22, p<.05), self-efficacy (r=.24, p<.05), and support from medical staff (r=.24, p<.05). The significant predictors of self-care performance included depression (${\beta}=-.28$), status of employment (${\beta}=-.27$), self-care knowledge (${\beta}=-.21$), support from medical staff (${\beta}=-.28$), and educational level (${\beta}=-.28$), accounting for 34% of the variance in the self-care performance. Conclusion: Depression, self-care knowledge, medical support are significant predictors which affect the self-care performance with PD patients.

This study was designed to identify the relation between health beliefs and compliance with weight control behavior in obese high school students living in Chonnam province. The data were collected from May 24 to 29, 1999. The instruments used in this study were modified by the authors on the basis of the results of the study's related references. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's Correlation using the SAS PC+ program. The results were as follows : 1. The correlation between health concern and compliance with weight control behavior was revealed as statistically significant (r= .34, p= .005). From the correlation of variables, it is concluded that there were statistically significant relations between health concern and benefit (r= .25, p= .043), between health concern and barrier (r= .33, p= .008), between susceptibility and severity (r= .64, p= .000), between susceptibility and benefit (r= .42, p= .000), between susceptibility and barrier (r= .44, p= .003), between severity and benefit (r= .37, p= .002), between severity and barrier (r= .56, p= .000), and between benefit and barrier (r= .38, p= .002). Thus, perceived susceptibility, perceived severity, perceived benefit, and perceived barrier had an indirect influence on compliance with weight control behavior. 2. In the analysis of the relationship between general characteristics and compliance with weight control behavior and health belief variables: Sex (t=2.56, p= .010) was revealed as the influencing variable of health concern. The number of those subjects living together (F=2.88, p= .044) was revealed as the influencing variable of susceptibility. Sex (t=3.47, p= .047), income (F=1.67, p= .051) was revealed as the influencing variable of barrier. 3. In the analysis of the relationship between obese characteristics and compliance with weight control behavior and health belief variables: Perception of weight (F=9.21, p= .000), family history of obesity (t=4.89, p= 030), environment of obesity (t=14.30, p= .000) were revealed as the influencing variables of susceptibility. Perception of weight (F=4.86, p= .001), symptoms of obesity (t=4.46, p= .006), family history of obesity (t=6.59, p= .012), environment of obesity (11.30, p= .001), and reasons of weight control (F=3.07, p= .010) were revealed as the influencing variables of severity. Symptoms of obesity (F=4.15, p= .009), reasons of weight control (F=2.41, p= .046) were revealed as the influencing variables of benefit. Environments of obesity (t=4.23, p= .044) were revealed as influencing variables of barrier. These results suggest that for improvement in compliance with weight control behavior, school nurses should stimulate the students' concerns about health.

Objective: The purpose of this study was to measure the morphological characteristics of the foot and biomechanical variables of the lower extremity joints during vertical jump and investigate the relationship between foot morphology and biomechanics of vertical jump. Method: 24 men in their 20s (age: 22.42 ± 1.41 yrs, height: 173.37 ± 4.61 cm, weight: 72.02 ± 6.21 kg, foot length: 251.70 ± 8.68 mm) participated in the study. Morphological characteristics of the foot included the length of the first toe, the length of the second toe, and the horizontal length from the center of ankle joint to the achilles tendon (Plantar Flexion Moment Arm [PFMA]). Biomechanical variables were measured for plantar flexor strength of the ankle joint and peak angular velocity, moment, and power of the lower extremity joint during vertical jump. Results: There was a significant correlation between the length of the first toe and plantar flexion strength at 30°/s [r=.440, p=.016], the angular velocity of the metatarsophalangeal [MTP] joint [r=-.369, p=.038] while significant correlations between PFMA and the angular velocities of the knee joint [r=.369, p=.038] and ankle joint [r=.420, p=.021] were found. There were also significant correlations between the length of the first toe and the maximum moment of the hip joint [r=.379, p=.034], and the length of the second toe and the power of the hip joint [r=-.391, p=.029]. Finally, significant correlations between PFMA and the power of the ankle joint [r=.424, p=.019] and MTP joint [r=.367, p=.039] were found. Conclusion: Based on the results of this study, the length of the toe and PFMA would be related to the function of the lower extremity joint. Therefore, this should be considered when designing the functional structure of a shoe. Furthermore, this relationship can be applied to intensive training for the plantar flexors and toe flexors to improve power in athletic performance.

For a map $p:X{\rightarrow}A$, there are concepts of co-$H^p$-spaces, co-$T^p$-spaces, which are generalized ones of co-H-spaces [17,18]. For a principal cofibration $i_r:X{\rightarrow}C_r$ induced by $r:X^{\prime}{\rightarrow}X$ from $\imath:X^{\prime}{\rightarrow}cX^{\prime}$, we obtain some sufficient conditions to having extensions co-$H^{\bar{p}}$-structures and co-$T^{\bar{p}}$-structures on $C_r$ of co-$H^p$-spaces and co-$T^p$-structures on X respectively. We can also obtain some results about co-$H^p$-spaces and co-$T^p$-spaces in homology decompositions for spaces, which are generalizations of Golasinski and Klein's result about co-H-spaces.

A bacteriocin-producing strain was isolated from kimchi at the early stage of kimchi fermentation. It was identified as Lactococcus lactis by morphological, cultural and physiological characteristics and partial sequence of 16S rDNA. The bacteriocin from isolate had antimicrobial activity against gram positive pathogenic bacteria, such as Listeria monocytogenes. Staphylococcus aureus and several strains of lactic acid bacteria but not to gram negative bacteria, Yersinia enterocolitica. The bacteriocin was sensitive to protease, protease ⅩⅣ, a-chymotrypsin and pepsin but not to lipase, trypsin and lysozyme. The bacteriocin activity was stable at pH 2-11 and temperature of 100 for 10 min. Thus, Listeria monocytogenes could be inhibited by Lactococcus lactis at early stage of fermentation.
