  • This study was done in order to analyze the relationship between Health condition, Health concept and Health promoting behavior in College Women. The subjects were 275 students from a college in Kyungbuk. The instruments used for this study were made of General characteristics (8 items), Health condition (3 item), Health concept (20 items) and Health promoting behaviors (40 items). The data were analyzed by SPSS/PC+ program using descriptive statistics, ANOVA, Pearson's Correlation Coefficient and Multiple Stepwise Regression. The results of this study were as follows. 1. The mean score of the Health promoting behavior was 2.3604. Among the subcategories, the highest degree of performance was interpersonal support (2.9133). 2. Health condition, Heath concept and Health promoting behavior according to general characteristics were as follows. 1)Perceived health condition had statistically significant differences according to board & lodging and living together (p=.040, p=.027). 2)Health concept had a statistically significant differences according to religion (p=.006). 3)Health promoting behavior had statistically significant differences according to age(p=.005). 4)Among the subcategory of Health promoting behavior, statistically significant differences were founded between nutrition and age / board & lodging (p=.004, p=.040), between self actualization and age(p=.006), between health responsibility and age/social economic status(p=.013, p=.000). 5. Correlations of Health condition, Health concept and Health promoting behavior were as follows. 1) BMI was positively correlated with perceived health status(r=.145, p=.015). 2)Health concept was positively correlated with BMI(r=.136, p=.032), perceived health condition(r=.148, p=.015), health promoting behavior (r=.316, p=.000). 6. Correlations of Health condition, Health concept and subcategories of Health promoting behavior were as follows. 1) Perceived health status was positively correlated nutrition (r=.168, p=.006). 2) Health concept was positively correlated with nutrition, stress management, self actualization and interpersonal relationship (r=.153 p=.011, r=.217 p=.000, r=.354 p=.000, r=.193 p=.001). 7. Health concept explained 10.1% of the variance for Health promoting behaviors.

  • 본 연구에서는 P300 문자입력기의 물리적 특성에 해당하는 문자판의 시각도와 사용자의 개인적 특성에 해당하는 시선응시 방법이 P300 문자입력기의 정확도에 미치는 영향을 검증하였다. 문자판의 시각도는 사용자와 문자판 간의 거리로 조작하였으며, 60 cm 집단과 100 cm 집단, 150 cm 집단으로 구성하였다. 시선응시방법은 세 조건으로 반복측정하였다. 머리 조건은 머리를 움직여서 시선을 두는 조건이었으며, 눈동자 조건은 머리는 고정한 채 눈동자를 움직여서 시선을 두는 조건이었고, 시선고정 조건은 시선을 문자입력기의 중앙에 고정시킨 조건이었다. 이요인설계에 의한 실험결과, 문자입력의 정확도가 시선응시방법에 따라 유의한 차이가 있었다. 머리 조건의 정확도가 눈동자 조건의 정확도 보다 높았으며, 눈동자 조건의 정확도가 시선고정 조건의 정확도 보다 높았다. 그러나 문자판의 시각도와 상호작용효과는 모두 유의하지 않았다. 시선응시방법에 따라 목표문자의 P300 진폭을 측정한 결과, 머리조건의 P300이 눈동자 조건의 P300보다 더 컸다. 머리조건과 눈동자 조건 간에는 오류분포에서 큰 차이가 없었지만, 시선고정 조건은 나머지 두 조건과 큰 차이를 보였다. 머리조건과 눈동자 조건에서는 오류가 주로 목표문자와 인접한 문자에서 나타난 반면, 시선고정 조건은 오류가 상대적으로 넓게 분포하였으며, 문자판의 중심에서 멀리 떨어져 있는 문자들에서 오류가 많이 발생하였다.

  • Batch cultivations were performed to evaluate the influences of the initial pH condition on mesophilic and thermophilic acidogenic fermentation with food waste recycling wastewater. In both conditions of mesophilic and thermophilic fermentation, TVFAs production rates were maximized at the initial pH 7 condition as 0.15 and 0.23 g TVFAs/L hr, respectively. And pH was also maintained stably between 6 and 7 during 72hr acidogenic cultivation at both conditions. However, predominant VFA components were different according to reaction temperature conditions. In mesophilic condition, propionic acid which has low conversion efficiency to methane was accumulated up to 1,348 mg/L while acetic and butyric acid were predominant in thermophilic condition. Therefore, thermophilic acidogenic fermentation was superior for the effective VFAs production than mesophilic condition. From the DGGE analysis, the band patterns were different according to the initial pH conditions but the correlations of the each band were increased in similar pH conditions. These results mean that microbial communities were certainly affected by the initial pH condition. Consequently, the adjustment of the initial pH to neutral region and thermophilic operation are needed to enhance acidogenic fermentation of food waste recycling wastewater.

  • In this paper we investigate the existence of weak solutions of a nonlinear beam equation under Dirichlet boundary condition on the interval $-\frac{\pi}{2}<x<\frac{\pi}{2}$ and periodic condition on the variable $t$, $u_{tt}+u_{xxxx}=p(x,t,u)$. We show that if $p$ satisfies condition $(p_1)-(p_3)$, then the nonlinear beam equation possesses at least one weak solution.

  • The pH as a control parameter for oxidation-reduction potential (ORP) was investigated through the denitrification by Ochrobactrum anthropi SY509 under non-growing condition. The optimal pH of nitrate reductase was 7.0, and the minimal ORP level was -250 mV for the denitrification under aerobic condition. In the case of anaerobic condition, the optimal pHs of nitrate and nitrite reductase were shifted to 10.0 and 9.0, respectively, and the minimal ORP levels of nitrate and nitrite reductase were decreased to -370 mV and -340mV, respectively. In the case of alkaline pH and anaerobic condition, the denitrification efficiency of nitrate was increased up to about 2-fold over that of neutral pH and anaerobic condition. Therefore, the combined control of pH and ORP in the anaerobic condition is shown to be an important parameter in the biological denitrification process.

  • In this paper, we initiate the study of some annihilator conditions on polynomials which were used by Kaplansky [4] to abstract algebras of bounded linear operators on a Hilbert spaces with Baer condition. On the other hand, p.p. rings were introduced by A. Hattori [3] to study the torsion theory. The purpose of this paper is to introduce near-rings with Baer condition and near-rings with p.p. condition which are somewhat different from the ring case, and to extend a results of Armendarz [1] to polynomial near-rings with Baer condition in somewhat different way of Birkenmeier and Huang [2].

  • 본 연구는 요부안정화에 도움이 되는 불안정 기저면의 운동인 공운동, 전신진동운동, 매트운동을 선택하여 각 운동조건의 체간과 하지의 근 활성도(%RVC)를 비교한 결과, 배속빗근은 전신진동기조건에서 매트조건보다 유의하게 증가하였고(p<.05), 넙다리곧은근과 장딴지안쪽갈래근은 공과 전신진동기조건에서 매트조건 보다 유의하게 증가하였으며(p<.05), 오금안쪽갈래근은 공조건에서 매트조건 보다 유의하게 증가하였다(p<.05). 세 가지 운동방법으로 4주간 안정화운동프로그램을 진행시킨 결과, 세 운동군 모두 운동전보다 운동 후에 각 방향에서 안정성한계의 유의한 증가가 있었다(p<.05). 각 운동군의 운동 전 후의 안정성한계의 차이 값을 비교한 결과, 각 운동군에서 네 방향(전 후 좌 우)의 안정성한계에 유의한 차이가 없었다(p>.05). 따라서 교각자세에서의 요부안정화 운동방법 중에서 체간근과 하지근육의 근활성도는 공과 전신진동기 운동에서 더 증가되었지만, 안정화운동 4주후에는 세 운동 모두 자세안정성을 증진시키는 것으로 나타났다.

  • Effect of temperature, pH and soil depth on germination of Dianthus chinensis, Dianthus barbatus, and Perennial pennant were investigated in growth chamber and soil condition at the ratio of 7:3 (natural soil and organic soil) in laboratory condition. the optimum temperature for seed germination was recorded for $20^{\circ}C-\;25^{\circ}C$. Maximum germination was observed for Dianthus barbatus (76%) where as in soil condition Perennial pennant (51%) showed maximum germination at 1 cm soil depth. Similarly, optimum pH for seed germination was at pH 6 in all the species. So in lower pH (at pH4) seed germination was inhibited. Germination of these selected species at different environmental condition help to construct the ecological sound proof wall to mitigate the noise especially in urban areas.
