본 연구는 공공도서관 사서들이 어려움을 느끼고 있는 평생교육 단위직무를 파악하고 동시에 재교육이 필요한 교육 내용에 대한 우선 순위를 맨휘트니(Mann Whitney U-test), 다중회귀분석(Multiple regression analysis)과 AHP(Analytic Hierarchy Process) 분석을 통해 제시하였다. 첫번째, 조사 대상 사서의 87%가 평생교육 직무는 보통이거나 어렵다고 인식하고 있었으며, 단위 업무별로는 운영계획수립을 가장 어려운 직무로 생각하고 있었다. 두번째, 평생교육사 자격이 있는 사서가 없는 경우에 비해 업무를 수월하게 인식하고 있었으며(P=0.04), 단위업무별로는 강사섭외(P=0.04), 운영계획수립(P=0.05)에 있어 유의한 차이가 검증되었다. 또한 평생교육관련 경력이 길수록 업무를 수월하게 (R=-0.217) 느끼는 것으로 나타났으며, 특히, 일정편성(R=-0.33), 진행업무(R=-0.22)에 있어, 통계적으로 유의한 상관성을 보였다. 세번째, 다중회귀분석 결과, 공공도서관 사서들이 평생교육업무 전반에 대하여 느끼는 체감 난이도에 유의한 영향을 주는 단위 직무는 운영계획수립(P=0.04)과 홍보(P=0.05) 업무인 것으로 나타났으며, 그중 운영계획수립(${\beta}=0.233$)이 체감 난이도 형성에 가장 많은 영향을 주는 요인인 것으로 판명되었다. 한편, 91%의 사서가 평생교육 직무 관련 재교육이 필요하다고 느끼고 있으며, 스피어만(Spearman rank-order correlation coefficient) 분석 결과(R=-0.210), 평생교육 업무에 대한 체감 난이도가 높은 사서일수록 재교육 필요성을 더욱 많이 느끼고 있는 것으로 나타났다. AHP 분석 결과 평생교육 직무 관련 재교육 내용은 이용자와의 소통(CU P=0.310), 기획(PL P=0.246), 마케팅(LM P=0.173) 순의 가중치를 보였으며, 도출된 CR(Consistency Ratio) 비율은 0.146으로 계산돼, 응답에 대한 일관성은 허용할 수 있는 수준인 것으로 나타났다.

Purpose: The purpose of this study was to determine the concurrent validity between Figure-of-8 Walking Test (F8W), Berg Balance Scale (BBS), Four Squared Step Test (FSST), and Timed UP and GO Test (TUG) in patients with stroke. Methods: Forty two participants (26 men, 16 women, $55.0{\pm}11.72$) with at least three months post stroke who were able to walk at least 10 m without walking aid participated in this study. Assessment of concurrent validity between the F8W (time and steps) and BBS was performed using Spearman rank order correlation and between the F8W (time and steps), FSST and TUG assessed using Pearson correlation. Results: The time of the F8W showed correlation with BBS (r=-0.46, p<0.01), FSST (r=0.64, p<0.01), and TUG (r=0.81, p<0.01), and steps of the F8W showed correlation with BBS (r=-0.43, p<0.01), FSST (r=0.47, p<0.01), and TUG (r=0.51, p<0.01). Conclusion: The F8W is a valid measure of balance and walking skill among patients with stroke and may provide complementary information with regard to dynamic balance and functional walking for the real life of stroke patients.

다시마 포자체에서 일어나는 광합성의 계절변화를 이해하기 위해, 1996년 2월부터 7월까지 동남해안에 양성한 엽체들의 광합성과 호흡률을 현장과 일정한 수온 및 영양염 조건으로 실험실에서 매월 측정하였다. 현장에서 측정한 P-I 매개변수는 계절적으로 변화하였다. 광합성력($P_{max}$)은 3월에 6.64 mg $O_2{\cdot}gdw^{-1}{\cdot}h^{-1}$로 최대였고, 이후 지속적으로 감소하였다. 광합성 효율(${\alpha}$)은 0.026~0.106의 범위였고, 광합성력과 유사한 시간변화를 보였다. 호흡률의 시간변화는 광합성력의 변화와 유의한 상관을 가지지 않았다. 호흡률은 0.25~0.83 mg $O_2{\cdot}gdw^{-1}{\cdot}h^{-1}$의 범위였다. 현장에서 측정한 광합성력은 중량의 상대성장률과 높은 상관을 지니고 있어, 광합성력이 증가함에 따라 체내에서 축적되는 물질의 양 또한 증가함을 알수 있었다. 현장과 실험실에서 측정한 광합성력을 비교한 결과, 2월내 현장에서의 광합성력이 낮았던 것은 이 기간 중 낮은 수온에 의한 영향 때문이었고, 3월 이후에 광합성력이 점진적으로 감소하는 것은 엽체의 연령증가에 따라 엽체의 두께가 증가하였기 때문이었다.4월에 측정한 엽체의 크기별 광합성력은 엽체의 두께와 광합성률간에는 음의 상관이 있다는 것을 나타내었다.

Parameters associated with solar minimum have been studied to relate them to solar activity at solar maximum so that one could possibly predict behaviors of an upcoming solar cycle. The number of active days has been known as a reliable indicator of solar activity around solar minimum. Active days are days with sunspots reported on the solar disk. In this work, we have explored the relationship between the sunspot numbers at solar maximum and the characteristics of the monthly number of active days. Specifically, we have statistically examined how the maximum monthly sunspot number of a given solar cycle is correlated with the slope of the linear relationship between monthly sunspot numbers and the monthly number of active days for the corresponding solar cycle. We have calculated the linear correlation coefficient r and the Spearman rank-order correlation coefficient $r_s$ for data sets prepared under various conditions. Even though marginal correlations are found, they turn out to be insufficiently significant (r ~ 0.3). Nonetheless, we have confirmed that the slope of the linear relationship between monthly sunspot numbers and the monthly number of active days is less steep when solar cycles belonging to the "Modern Maximum" are considered compared with rests of solar cycles. We conclude, therefore, that the slope of the linear relationship between monthly sunspot numbers and the monthly number of active days is indeed dependent on the solar activity at its maxima, but that this simple relationship should be insufficient as a valid method to predict the following solar activity amplitude.

Objectives: The objectives of this study were to determine the psychological fatigue and analyze muscle activity of production workers who are performing processes jobs while standing for prolonged time periods. Methods: The psychological fatigue experienced by the workers was obtained through questionnaire surveys. Meanwhile, muscle activity has been analyzed using surface electromyography (sEMG) measurement. Lower extremities muscles include: erector spinae, tibialis anterior, and gastrocnemius were concurrently measured for more than five hours of standing. Twenty male production workers in a metal stamping company participated as subjects in this study. The subjects were required to undergo questionnaire surveys and sEMG measurement. Results: Results of the questionnaire surveys found that all subjects experienced psychological fatigue due to prolonged standing jobs. Similarly, muscle fatigue has been identified through sEMG measurement. Based on the non-parametric statistical test using the Spearman's rank order correlation, the left erector spinae obtained a moderate positive correlation and statistically significant ($r_s$ = 0.552, p < 0.05) between the results of questionnaire surveys and sEMG measurement. Conclusion: Based on this study, the authors concluded that prolonged standing was contributed to psychological fatigue and to muscle fatigue among the production workers.

Balance is a complex motor skill that depends on interactions between multiple sensorimotor processes and environmental and functional contexts. Many rehabilitation specialists believe that balance assessment under multitask conditions may be a more sensitive indicator of balance problems and falls than balance assessment in a single-task context. Functional Gait Assessment has many tasks that allow for testing under multitask conditions. The purpose of this study was to determine the concurrent validity between the Functional Gait Assessment (FGA), Berg Balance Scale (BBS), and Timed "Up & Go" Test (TUG) in patients with stroke. One hundred and five participants with at least 3 months post stroke and able to walk at least 6 m with or without a mono cane, participated in this study. Concurrent validity between the FGA, BBS, and TUG was assessed using Spearman rank order correlation. The FGA correlated with the BBS (r=.80, p<.01) and TUG (r=-.77, p<.01). The good and moderate correlation between the FGA, BBS, and TUG establishes the concurrent validity of the FGA in patients with stroke. These measures provide clinicians with valuable information about patients' functional balance capabilities.

Purpose: This study aimed to compare the health service delivery level and educational needs by work experiences and types of public health center among the nurses who work as visiting health services workers at public health centers. Methods: Data collected from 484 nursing staff for 2 weeks, was analyzed using the SPSS program t-test, ANOVA, and Spearman Rank-Order Correlation. Nurses with more than 2 years experience were 79.1%; and 43.6% of the subjects worked within Gun type public health centers. Results: The health service performance frequency of metropolitan city type public health centers was significantly high in the areas of education, behavior pattern, chronic disease, pregnant women & infants, and multi-cultural family. The health service performance frequency of Gun type public health centers was significantly high in the areas of type of test, fundamental nursing, and basic rehabilitation. In addition, the correlation between the performance frequency and educational needs was positively correlated, and the subjects with greater educational needs performed more. Conclusion: Educational programs should be designed according to the types of public health centers rather than work experiences, especially in systematic training for frequently performed items after reviewing the practice precisely.

This study investigates the influence of Likert scale formats such as the number of response categories and the inclusion of a mid-point from a methodological point of view using instruments that measure a fashionmarketing-related subject. Using a self-administered questionnaire, 201 respondents rated their economic clothing shopping orientation on three formats of scales that differed only in the number of response categories (ranging from 5 to 7) from February 8 to February 12, 2010. Descriptive statistics, Spearman's rank order correlation, t-test, exploratory factor analysis, confirmatory factor analysis, Pearson's correlation, and Cronbach's alpha were used in the analysis. The results are as follows. First, three scale formats were generally suitable for use due to validity and reliability. Second, the response results varied with the number of categories and the inclusion of a mid-point, although the differences were statistically insignificant (with only a few cases that differed). Third, construct validity was more secure in scales with fewer categories, whereas convergent and discriminant validity was generally good in all scale formats. Fourth, reliability coefficients were higher in scales with more categories. Fifth, the number of categories was of greater importance to instrument design than the inclusion of a mid-point. Implications for appropriate scale designs are suggested in this study.
