Purpose: The purpose of this study was to verify the relationship among depression, school adjustment, parent-child bonding, parental control and smartphone addiction, and to identify factors which influence smartphone addiction in adolescents. Methods: A cross-sectional design was used, with a convenience sample of 183 middle school students from 3 middle schools. Data collection was conducted through self-report questionnaires from April to May, 2017. Data were analyzed using ${\chi}^2$ test, Fisher's exact test, t-test, one-way ANOVA, correlation coefficient analysis, and binary logistic regression with SPSS Ver. 21.0. Results: The mean score for smartphone addiction was 29.40. Of the adolescents, 21.3% were in the smartphone addiction risk group. Logistic regression analysis showed that gender (OR=7.09, 95% Cl: 2.57~19.52), school life (OR=0.86, 95% Cl: 0.79~0.93), smartphone usage time (OR=1.32, 95% Cl: 1.04~1.66), and parental control (OR=4.70, 95% Cl: 1.04~21.29) were effect factors for the smartphone addiction risk group. Conclusion: Findings indicate that school satisfaction was an important factor in adolescents' smartphone addiction. Control oriented parent management of adolescents' smartphone use did not reduce the risk of smartphone addiction and may have worsen the addiction. Future research is needed to improve understanding of how teachers and parents will manage their adolescents' use of smartphones.

The purpose of this research is to examine resource characteristics affecting the overall recreation suitability of natural recreation forest. On the basis of resource-based approach, we had constructed a conceptual framework for this research and found one dependent variable of the overall recreation suitability and eight independent variables, representing characteristics of recreation resource. After questionnaire surveying of 690 visitors from 10 among 72 natural recreation forests in Korea. We have analyzed the data using descriptive statistics, correlation analysis, and multiple linear regression method. We have found that 1) physical factor of recreation resources turned out to be statistically insignificant and the direction of relationship between independent variable and dependent variable is the same as that of dependent variable, 2) noise, sound and smell turned out to be the most important variable in terms of magnitude of independent variable and wild life turned out to be the next important variable, and 3) noise, sound and smell turned out to have aboutn 3.3 times greater thant that of landscape, judging from the absolute value of standardized regression coefficient. The research findings can be used for planning and designing of natural recreation forests based on recreation suitability of forest resources, and will provide pertinent guidelines for management of recreation resources of natural recreation forests. The approach and method of evaluating recreation suitability employed in this research provide us valid and reliable results and will be highly useful in other resource-based recreation development. We suggest that the differences in recreation suitability between private and public recreation forests and the relationship between user-satisfaction and recreation suitability of natural recreation forests must be examined in the future research.

The main attributes of yogurt that affect consumer satisfaction are taste, consistency, and a firm texture. This study evaluates the influence of xanthan gum, barley beta-glucan, and guar gum in concentrations of 0.05%, 0.1%, 0.2%, and 0.3% on probiotic yogurt. The set-type yogurt samples were prepared by using raw cow's milk. The statistical analysis showed that none of these gum additions had any marked effect on pH, titratable acidity, total solids content, and probiotic bacteria counts of yogurt samples. Evaluations for syneresis and water-holding capacity (WHC) in the yogurt samples were affected by the type and concentration of the stabilizer. Yogurts treated with 0.1% xanthan gum and 0.3% beta-glucan recorded the highest WHC and the least syneresis. The largest amount of gel firmness was recorded in yogurt samples treated with 0.2% xanthan gum and 0.3% beta-glucan. Yogurt samples treated with 0.1% xanthan gum and 0.3% beta-glucan were considered acceptable by trained panelists and gained the highest scores in sensory evaluations. The correlation coefficient between the amount of syneresis, WHC and stiffness of texture was significant compared to scores for sensory evaluation (p<0.01). Results for effects of guar gum on the tested parameters were contrary to the results expected from a gum. According to this study, the use of xanthan gum and beta-glucan are highly recommended for low-fat yogurt production.

This study was conducted to assess factors associated with the degree of performance of qualify improvement(QI) activities. A mailed questionnaire survey was conducted between September 15 and October 30, 2000, with the staffs being charge of QI at each of the hospitals with 400 beds or greater. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used for the analysis. Using the Malcolm Baldrige National Quality Award Criteria(MBNQAC), perceived performance of QI was measured in terms of the improvement of the quality of clinical practice, clinical supporting department, administrative procedure of receiving care, customer satisfaction, efficiency and standardization of work process. Factors evaluated for the association were the extent of QI implementation, compliance to 5 QI principles, participation of hospital CEOs, budget allocation, history of QI, and bed size. Path analysis was performed to assess the relationship between QI performance and these factors. Major findings of this study are as follows. Hospitals showing higher degree of QI implementation (path coefficient=0.5967, p<0.001)) and better compliance with the basic principes of QI(0.5736, p<0.05) tended to achieve better performance. Path analysis results showed that interest and participation of hospital CEOs(0.1954, p<0.05) and compliance with the basic principes of QI(0.4028, p<0.0001) indirectly affected the outcomes of QI by influencing the intermediate variable of the level of QI implementation. This study results suggest that having employees have a good orientation of the basic concept and principes of QI through relevant training be the most important requirement to achieve better outcomes from QI activities. In addition, to educate leaders of hospitals the need of active implementation of QI is important to encourage their participation and draw strong support for QI programs.

본 연구의 목적은 수용성고분자 PVA의 한외여과 실험을 통해 한계투과량(limiting flux) 현상에 미치는 조업변수들의 효과들을 고찰하고, 또한 겔층모델(gel-layer model)의 한계성을 극복하기 위해 열전달 계수의 개념을 도입한 Amiar 모델식을 바탕으로 새로운 모델식을 제시하여 이의 적용 가능성을 살펴보았다. Polysulfone 재질의 평판막(MWCO=20,000)과 중공사형막(MWCO= 30,000)을 사용하여 막내선속도, 투과압력, 온도, PVA 농도 등의 변화에 따른 한외여과 특성을 살펴보았다. 실험결과를 통해 polysulfone 재질의 막을 통해 PVA의 한외여과 과정은 겔층형성에 따른 투과저항 메커니즘이 작용하는 것으로 나타났다. 반면에 중공사형막의 경우는 한계투과량 조건하에서 겔층모델에 의해 예측할 수 없는 upward 한계투과량 현상이 관측되었다. 점성도 보정인자(viscosity correction factor)가 포함된 새로운 모델식의 적용을 통해서 upward 한계투과량 현상을 예측하였으나 완전히 만족할만한 결과를 얻지 못했다. 그러나 이와 같은 모델식의 적용을 통해서 PVA의 한외여과 과정이 투과용액의 점성도와 매우 밀접한 관계를 가짐을 알 수 있었다.
